This study investigated the effect of swimming exercise training on thoracotomy and rib retraction-induced allodynia. Methods: Male Sprague Dawley rats that received animal model of persistent postthoracotomy pain. All rats were divided into three groups: sham operations group (Sham), thoracotomy and rib retraction group (TRR), and TRR with swimming exercise training for 90min/day, 7 days a week for 4 weeks (TRR-SEW). The sham group did not receive retraction of the ribs. Thus, they received a pleural incision. The levels of mechanical and cold allodynia were measured by von Frey and acetone test. Results: In von Frey test, the level of mechanical allodynia in the TRR group was significantly higher than the sham group. The level of mechanical allodynia in the TRR-SEW group was significantly lower than the TRR group. In acetone test, the level of cold allodynia in the TRR group was significantly higher than the sham group. The level of cold allodynia in the TRR-SEW group was significantly lower than the TRR group. Conclusions: These results suggest that swimming exercise training decreases persistent postthoracotomy pain caused by TRR surgery. It may provide one of the new therapeutic effects of swimming exercise training could alleviate persistent postthoracotomy pain. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=chronic%20pain" title="chronic pain">chronic pain</a>, <a href="https://publications.waset.org/abstracts/search?q=thoracotomy%20pain" title=" thoracotomy pain"> thoracotomy pain</a>, <a href="https://publications.waset.org/abstracts/search?q=swimming" title=" swimming"> swimming</a>, <a href="https://publications.waset.org/abstracts/search?q=von%20Frey%20test" title=" von Frey test"> von Frey test</a>, <a href="https://publications.waset.org/abstracts/search?q=acetone%20test" title=" acetone test"> acetone test</a> </p> <a href="https://publications.waset.org/abstracts/77826/effects-of-swimming-exercise-training-on-persistent-pain-in-rats-after-thoracotomy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/77826.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">218</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">26</span> Cucurbita pepo L. Attenuates Diabetic Neuropathy by Targeting Oxidative Stress in STZ-Nicotinamide Induced Diabetic Rats</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Navpreet%20Kaur">Navpreet Kaur</a>, <a href="https://publications.waset.org/abstracts/search?q=Randhir%20Singh"> Randhir Singh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Diabetic neuropathy is one of the most common microvascular complications of diabetes mellitus which affects more than 50% of diabetic patients. The present study targeted oxidative stress mediated nerve damage in diabetic rats using a hydro-alcohol extract of Cucurbita pepo L. (Family: Cucurbitaceae) and its potential in treatment of diabetic neuropathy. Diabetes neuropathy was induced in Wistar rats by injection of streptozotocin (65 mg/kg, i.p.) 15 min after Nicotinamide (230 mg/kg, i.p.) administration. Hydro-alcohol extract of C. pepo seeds was assessed by oral administration at 100, 200 and 400 mg/kg in STZ-nicotinamide induced diabetic rats. Thermal hyperalgesia (Eddy's hot plate and tail immersion), mechanical hyperalgesia (Randall-Selitto) and tactile allodynia (Von Frey hair tests) were evaluated in all groups of streptozotocin diabetic rats to assess the extent of neuropathy. Tissue (sciatic nerve) antioxidant enzymes (SOD, CAT, GSH and LPO) levels were measured along with the formation of AGEs in serum to assess the effect of hydro-alcohol extract of C. pepo in ameliorating oxidative stress. Diabetic rats exhibited significantly decreased tail-flick latency in the tail-immersion test and decreased paw withdrawal threshold in both Randall-Selitto and von-Frey hair test. A decrease in the nociceptive threshold was accompanied by significantly increased oxidative stress in sciatic nerve of diabetic rats. Treatment with the C. pepo hydro-alcohol extract significantly attenuated all the behavioral and biochemical alterations in a dose-dependent manner. C. pepo attenuated the diabetic condition and also reversed neuropathic pain through modulation of oxidative stress and thus it may find application as a possible therapeutic agent against diabetic neuropathy. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=advanced%20glycation%20end%20products" title="advanced glycation end products">advanced glycation end products</a>, <a href="https://publications.waset.org/abstracts/search?q=antioxidant%20enzymes" title=" antioxidant enzymes"> antioxidant enzymes</a>, <a href="https://publications.waset.org/abstracts/search?q=cucurbita%20pepo" title=" cucurbita pepo"> cucurbita pepo</a>, <a href="https://publications.waset.org/abstracts/search?q=hyperglycemia" title=" hyperglycemia"> hyperglycemia</a> </p> <a href="https://publications.waset.org/abstracts/42884/cucurbita-pepo-l-attenuates-diabetic-neuropathy-by-targeting-oxidative-stress-in-stz-nicotinamide-induced-diabetic-rats" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/42884.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">297</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">25</span> Amniotic Fluid Mesenchymal Stem Cells Selected for Neural Specificity Ameliorates Chemotherapy Induced Hearing Loss and Pain Perception</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jan%20F.%20Talts">Jan F.

Clinically, CIPN is a mostly sensory neuropathy leading to pain and to motor and autonomic changes. Due to its high prevalence among cancer patients, CIPN constitutes a major problem for both cancer patients and survivors, especially because currently, there is no single effective method of preventing CIPN. Hearing loss is the most common form of sensory impairment in humans and can be caused by ototoxic chemical compounds such as chemotherapy (platinum-based antineoplastic agents).In rodents, single or repeated cisplatin injections induce peripheral neuropathy and hearing impairment mimicking human disorder, allowing studying the efficacy of new pharmacological candidates in chemotherapy-induced hearing loss and peripheral neuropathy. RNA sequencing data from full term amniotic fluid (TAF) mesenchymal stemcell (MSC) clones was used to identify neural-specific markers present on TAF-MSC. Several prospective neural markers were tested by flow cytometry on cultured TAF-MSC. One of these markers was used for cell-sorting using Tyto MACSQuant cell sorter, and the neural marker positive cell population was expanded for several passages to the final therapeutic product stage. Peripheral neuropathy and hearing loss was induced in mice by administration of cisplatin in three week-long cycles. The efficacy of neural-specific TAF-MSC in treating hearing loss and pain perception was evaluated by administration of three injections of 3 million cells/kg by intravenous route or three injections of 3 million cells/kg by intra-arterial route after each cisplatin cycle treatment. Auditory brainstem responses (ABR) are electric potentials recorded from scalp electrodes, and the first ABR wave represents the summed activity of the auditory nerve fibers contacting the inner hair cells. For ABR studies, mice were anesthetized, then earphones were placed in the left ear of each mouse, an active electrode was placed in the vertex of the skull, a reference electrode under the skin of the mastoid bone, and a ground electrode in the neck skin. The stimuli consisted of tone pips of five frequencies (2, 4, 6, 12, 16, and 24 kHz) at various sound levels (from 0 to 90 dB) ranging to cover the mouse auditory frequency range. The von Frey test was used to assess the onset and maintenance of mechanical allodynia over time. Mice were placed in clear plexiglass cages on an elevated mesh floor and tested after 30 min of habituation. Mechanical paw withdrawal threshold was examined using an electronic von Frey anesthesiometer. Cisplatin groups treated with three injections of 3 million cells/kg by intravenous route and three injections of 3 million cells/kg by intra-arterial route after each cisplatin cycle treatment presented, a significant increase of hearing acuity characterized by a decrease of ABR threshold and a decrease of neuropathic pain characterized by an increase of von Frey paw withdrawal threshold compared to controls only receiving cisplatin. This study shows that treatment with MSCselected for neural specificity presents significant positive efficacy on the chemotherapy-induced neuropathic pain and the chemotherapy-induced hearing loss. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=mesenchymal%20stem%20cell" title="mesenchymal stem cell">mesenchymal stem cell</a>, <a href="https://publications.waset.org/abstracts/search?q=peripheral%20neuropathy" title=" peripheral neuropathy"> peripheral neuropathy</a>, <a href="https://publications.waset.org/abstracts/search?q=amniotic%20fluid" title=" amniotic fluid"> amniotic fluid</a>, <a href="https://publications.waset.org/abstracts/search?q=regenerative%20medicine" title=" regenerative medicine"> regenerative medicine</a> </p> <a href="https://publications.waset.org/abstracts/152319/amniotic-fluid-mesenchymal-stem-cells-selected-for-neural-specificity-ameliorates-chemotherapy-induced-hearing-loss-and-pain-perception" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/152319.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">166</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">24</span> Innovative Biomonitoring in Port Ecosystem: Lessons and Perspectives from the QUAMPO Project</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Benedicte%20Madon">Benedicte Madon</a>, <a href="https://publications.waset.org/abstracts/search?q=Marion%20Pillet"> Marion Pillet</a>, <a href="https://publications.waset.org/abstracts/search?q=Justine%20Castrec"> Justine Castrec</a>, <a href="https://publications.waset.org/abstracts/search?q=Quentin%20Fonatine"> Quentin Fonatine</a>, <a href="https://publications.waset.org/abstracts/search?q=Pierre%20Lejeune"> Pierre Lejeune</a>, <a href="https://publications.waset.org/abstracts/search?q=Michel%20Marengo"> Michel Marengo</a>, <a href="https://publications.waset.org/abstracts/search?q=Helene%20Thomas"> Helene Thomas</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Biodiversity in port ecosystems faces many anthropic pressures from port activities.

Persistent widespread pain and generalized tenderness are the characteristic symptoms affecting a large majority of the global population, particularly females. This disease has indicated a refractory tendency to conventional treatment ventures, largely resultant from a lack of etiological and pathogenic understanding of the disease development. Emerging evidence indicates that the central nervous system (CNS) plays a critical role in the amplification of pain signals and the neurotransmitters associated therewith. Various stimuli have been found to activate the channels existent on nociceptor terminals, thereby actuating nociceptive impulses along the pain pathways. The transient receptor potential vanalloid 1 (TRPV1) channel functions as a molecular integrator for numerous sensory inputs, such as nociception, and was explored in the current study. Current intervention approaches face a multitude challenges, ranging from effective therapeutic interventions to the limitation of pathognomonic criteria resultant from incomplete understanding and partial evidence on the mechanisms of action of FM. It remains unclear whether electroacupuncture (EA) plays an integral role in the functioning of the TRPV1 pathway, and whether or not it can reduce the chronic pain induced by FM. Aims: The aim of this study was to explore the mechanisms underlying the activation and modulation of the TRPV1 channel pathway in a cold stress model of FM applied to a murine model. Furthermore, the effect of EA in the treatment of mechanical and thermal pain, as expressed in FM was also to be investigated. Methods: 18 C57BL/6 wild type and 6 TRPV1 knockout (KO) mice, aged 8-12 weeks, were exposed to an intermittent cold stress-induced ﬁbromyalgia-like pain model, with or without EA treatment at ZusanLi ST36 (2Hz/20min) on day 3 to 5. Von Frey and Hargreaves behaviour tests were implemented in order to analyze the mechanical and thermal pain thresholds on day 0, 3 and 5 in control group (C), FM group (FM), FM mice with EA treated group (FM + EA) and FM in KO group. Results: An increase in mechanical and thermal hyperalgesia was observed in the FM, EA and KO groups when compared to the control group. This initial increase was reduced in the EA group, which directs focus at the treatment efficacy of EA in nociceptive sensitization, and the analgesic effect EA has attenuating FM associated pain. Discussion: An increase in the nociceptive sensitization was observed through higher withdrawal thresholds in the von Frey mechanical test and the Hargreaves thermal test. TRPV1 function in mice has been scientifically associated with these nociceptive conduits, and the increased behaviour test results suggest that TRPV1 upregulation is central to the FM induced hyperalgesia. This data was supported by the decrease in sensitivity observed in results of the TRPV1 KO group. Moreover, the treatment of EA showed a decrease in this FM induced nociceptive sensitization, suggesting TRPV1 upregulation and overexpression can be attenuated by EA at bilateral ST36. This evidence compellingly implies that the analgesic effect of EA is associated with TRPV1 downregulation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fibromyalgia" title="fibromyalgia">fibromyalgia</a>, <a href="https://publications.waset.org/abstracts/search?q=electroacupuncture" title=" electroacupuncture"> electroacupuncture</a>, <a href="https://publications.waset.org/abstracts/search?q=TRPV1" title=" TRPV1"> TRPV1</a>, <a href="https://publications.waset.org/abstracts/search?q=nociception" title=" nociception"> nociception</a> </p> <a href="https://publications.waset.org/abstracts/84634/the-analgesic-effect-of-electroacupuncture-in-a-murine-fibromyalgia-model" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/84634.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">139</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">21</span> Processes of Identities Formation and Transformation among Professional Skilled Mexican Migrants in the United States</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20Laura%20Vazquez%20Maggio">M.

Following the idea that identities are never singular, multifaceted and have a necessarily processual character, the authors specifically analyze three dimensions of the identity of qualified Mexican migrants in the US and the interplay between them. Drawing on semi-structured interviews with skilled Mexican middle-class migrants in the US, the paper explores how skilled Mexican migrants preserve their ethno-national identity (their ‘Mexicanness’) in reaction to a hostile socio-political reception context in the US. It further shows how these migrants recreate their class identity and show tendencies to distance themselves from what they perceive as lower-class Mexican migrants and the dominant popular Mexican and Latin-American cultural expressions. In a final step, it examines how the lived experience of migration itself impacts the migrants’ identities, their concept of self and feelings/modes of being and belonging. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ethno-national%20identity" title="ethno-national identity">ethno-national identity</a>, <a href="https://publications.waset.org/abstracts/search?q=middle%20class%20identity" title=" middle class identity"> middle class identity</a>, <a href="https://publications.waset.org/abstracts/search?q=middle-class%20migration" title=" middle-class migration"> middle-class migration</a>, <a href="https://publications.waset.org/abstracts/search?q=migrants%E2%80%99%20identity" title=" migrants’ identity"> migrants’ identity</a>, <a href="https://publications.waset.org/abstracts/search?q=skilled%20migration" title=" skilled migration"> skilled migration</a> </p> <a href="https://publications.waset.org/abstracts/123405/processes-of-identities-formation-and-transformation-among-professional-skilled-mexican-migrants-in-the-united-states" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/123405.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">143</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">20</span> Physical Interaction Mappings: Utilizing Cognitive Load Theory in Order to Enhance Physical Product Interaction</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bryan%20Young">Bryan Young</a>, <a href="https://publications.waset.org/abstracts/search?q=Andrew%20Wodehouse"> Andrew Wodehouse</a>, <a href="https://publications.waset.org/abstracts/search?q=Marion%20Sheridan"> Marion Sheridan </a> </p> <p class="card-text"><strong>Abstract:</strong></p> The availability of working memory has long been identified as a critical aspect of an instructional design. Many conventional instructional procedures impose irrelevant or unrelated cognitive loads on the learner due to the fact that they were created without contemplation, or understanding, of cognitive work load. Learning to physically operate traditional products can be viewed as a learning process akin to any other. As such, many of today's products, such as cars, boats, and planes, which have traditional controls that predate modern user-centered design techniques may be imposing irrelevant or unrelated cognitive loads on their operators. The goal of the research was to investigate the fundamental relationships between physical inputs, resulting actions, and learnability. The results showed that individuals can quickly adapt to input/output reversals across dimensions, however, individuals struggle to cope with the input/output when the dimensions are rotated due to the resulting increase in cognitive load. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cognitive%20load%20theory" title="cognitive load theory">cognitive load theory</a>, <a href="https://publications.waset.org/abstracts/search?q=instructional%20design" title=" instructional design"> instructional design</a>, <a href="https://publications.waset.org/abstracts/search?q=physical%20product%20interactions" title=" physical product interactions"> physical product interactions</a>, <a href="https://publications.waset.org/abstracts/search?q=usability%20design" title=" usability design"> usability design</a> </p> <a href="https://publications.waset.org/abstracts/19122/physical-interaction-mappings-utilizing-cognitive-load-theory-in-order-to-enhance-physical-product-interaction" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/19122.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">537</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">19</span> Orthophthalic Polyester Composite Reinforced with Sodium Alginate-Treated Anahaw (Saribus rotundifolius) Fibers</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Terence%20Tumolva">Terence Tumolva</a>, <a href="https://publications.waset.org/abstracts/search?q=Johannes%20Kristoff%20Vito"> Johannes Kristoff Vito</a>, <a href="https://publications.waset.org/abstracts/search?q=Joanna%20Crystelle%20Ragasa"> Joanna Crystelle Ragasa</a>, <a href="https://publications.waset.org/abstracts/search?q=Renz%20Marion%20Dela%20Cruz"> Renz Marion Dela Cruz</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Natural fiber reinforced polymer (NFRP) composites have been the focus of various research projects due to their advantages over synthetic fiber-reinforced composites. For this study, ana haw is used as the fiber source due to its abundance throughout the Philippines. A problem addressed in this study is the need for an environment-friendly method of fiber treatment. The use of sodium alginate to treat fibers was thus investigated. The fibers were immersed in a sodium alginate solution and then in a calcium chloride solution afterwards. The treated fibers were used to reinforce orthophthalic unsaturated polyester (ortho-UP) resin. The mechanical properties were tested using a universal testing machine (UTM), and the fracture surfaces were characterized using scanning electron microscope (SEM). Results showed that the sodium alginate treatment had increased the tensile and flexural strength of the composite. The increase in fiber load had also been found to increase the stiffness of the composite. However, sodium alginate treatment did not provide any significant improvement in the wet mechanical properties of the NFRP. The composite is comparable to some commercially available polymeric materials. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=NFRP" title="NFRP">NFRP</a>, <a href="https://publications.waset.org/abstracts/search?q=composite" title=" composite"> composite</a>, <a href="https://publications.waset.org/abstracts/search?q=alginate" title=" alginate"> alginate</a>, <a href="https://publications.waset.org/abstracts/search?q=anahaw" title=" anahaw"> anahaw</a>, <a href="https://publications.waset.org/abstracts/search?q=polymer" title=" polymer"> polymer</a> </p> <a href="https://publications.waset.org/abstracts/52227/orthophthalic-polyester-composite-reinforced-with-sodium-alginate-treated-anahaw-saribus-rotundifolius-fibers" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/52227.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">337</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">18</span> Psychological Capital and Work Engagement as Predictors of Employee Performance in a Technology Industry During COVID-19 Pandemic: Basis for Performance Management</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Marion%20Francisco">Marion Francisco</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The study sought to investigate the psychological capital and work engagement of employees as predictors of employee performance in the technology industry in Makati City.

A convenience sampling technique was used to gather data samples from 100 populations with the help of Roscoe concept approach. The study revealed that both psychological capital and work engagement have a significant relationship with employee performance. Psychological capital and work engagement can predict employee performance of the respondents. With the results given, the study suggests: (1) to focus on maintaining a high level of psychological capital and work engagement, on achieving a very high level of psychological capital and work engagement, and on improving the low level of psychological capital or work engagement mostly during this COVID-19 pandemic using the proposed employee performance management plan and (2) to create a proposed employee performance management plan as necessary to tailor fit on employees needs to enhance their performance that will help meet company and client’s needs. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=employee%20performance" title="employee performance">employee performance</a>, <a href="https://publications.waset.org/abstracts/search?q=performance%20management" title=" performance management"> performance management</a>, <a href="https://publications.waset.org/abstracts/search?q=psychological%20capital" title=" psychological capital"> psychological capital</a>, <a href="https://publications.waset.org/abstracts/search?q=technology%20industry" title=" technology industry"> technology industry</a>, <a href="https://publications.waset.org/abstracts/search?q=work%20engagement" title=" work engagement"> work engagement</a> </p> <a href="https://publications.waset.org/abstracts/164310/psychological-capital-and-work-engagement-as-predictors-of-employee-performance-in-a-technology-industry-during-covid-19-pandemic-basis-for-performance-management" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/164310.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">112</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">17</span> Diving Behaviour of White-Chinned Petrels and Its Relevance for Mitigating Longline Bycatch</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=D.%20P.%20Rollinson">D.

Despite the importance of diving ability for mitigating longline bycatch, little is known of this species’ diving behaviour. We obtained data from temperature–depth recorders from nine white-chinned petrels breeding on Marion Island, southwestern Indian Ocean, during the late incubation and chickrearing period. Maximum dive depth (16 m) was slightly deeper than the previous estimate (13 m), but varied considerably among individuals (range 2–16 m). Males dived deeper than females, and birds feeding chicks dived deeper than incubating birds, but dive rate did not differ between the sexes. Time of day had no significant effect on dive depth or rate. Our findings will help to improve the design and performance of mitigation measures aimed at reducing seabird bycatch in longline fisheries, such as the calculation of minimum line sink rates and optimum aerial coverage of bird-scaring lines. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=dive%20depth" title="dive depth">dive depth</a>, <a href="https://publications.waset.org/abstracts/search?q=dive%20duration" title=" dive duration"> dive duration</a>, <a href="https://publications.waset.org/abstracts/search?q=temperature%E2%80%93depth%20recorders" title=" temperature–depth recorders"> temperature–depth recorders</a>, <a href="https://publications.waset.org/abstracts/search?q=seabirds" title=" seabirds"> seabirds</a>, <a href="https://publications.waset.org/abstracts/search?q=bird-scaring%20lines" title=" bird-scaring lines"> bird-scaring lines</a> </p> <a href="https://publications.waset.org/abstracts/15502/diving-behaviour-of-white-chinned-petrels-and-its-relevance-for-mitigating-longline-bycatch" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/15502.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">573</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">16</span> Relationships between Financial, Cultural, Emotional, and General Wellbeing: A Structural Equation Modeling Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Michael%20Alsop">Michael Alsop</a>, <a href="https://publications.waset.org/abstracts/search?q=Hannah%20Heitz"> Hannah Heitz</a>, <a href="https://publications.waset.org/abstracts/search?q=Prathiba%20Natesan%20Batley"> Prathiba Natesan Batley</a>, <a href="https://publications.waset.org/abstracts/search?q=Marion%20Hambrick"> Marion Hambrick</a>, <a href="https://publications.waset.org/abstracts/search?q=Jason%20Immekus"> Jason Immekus</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The impacts of cultural engagement on individuals’ health and well-being have been well documented. The purposes of this study were to create an instrument to measure wellbeing constructs, including cultural wellbeing, and explore the relationships between cultural wellbeing and other wellbeing constructs (e.g., emotional, social, physical, spiritual). A sample of 358 participants attending concerts performed by a civic orchestra in the southeastern United States completed a questionnaire designed to measure eight wellbeing constructs. Split-half exploratory, confirmatory factor analyses resulted in the retention of four wellbeing constructs: general, emotional, financial, and cultural. Structural equation modeling showed statistically significant relationships between cultural wellbeing and other wellbeing constructs. In addition to the indirect effect of financial wellbeing on emotional and general wellbeing through cultural wellbeing, there were also direct statistically significant relationships (i.e., moderator). This highlights the importance of removing financial barriers to cultural engagement and the relationship between cultural wellbeing on emotional and general wellbeing. Additionally, the retained cultural wellbeing items focused primarily on community features, indicating the value of community-based cultural engagement opportunities. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cultural%20wellbeing" title="cultural wellbeing">cultural wellbeing</a>, <a href="https://publications.waset.org/abstracts/search?q=cultural%20engagement" title=" cultural engagement"> cultural engagement</a>, <a href="https://publications.waset.org/abstracts/search?q=factor%20analysis" title=" factor analysis"> factor analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=structural%20equation%20modeling" title=" structural equation modeling"> structural equation modeling</a> </p> <a href="https://publications.waset.org/abstracts/167360/relationships-between-financial-cultural-emotional-and-general-wellbeing-a-structural-equation-modeling-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/167360.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">82</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">15</span> Electroencephalogram Study of Change Blindness in Mindful Subjects</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lea%20Lachaud">Lea Lachaud</a>, <a href="https://publications.waset.org/abstracts/search?q=Aida%20Raoult"> Aida Raoult</a>, <a href="https://publications.waset.org/abstracts/search?q=Marion%20Trousselard"> Marion Trousselard</a>, <a href="https://publications.waset.org/abstracts/search?q=Francois%20B.%20Vialatte"> Francois B. Vialatte</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper addresses mindfulness from a psychological and neuroscientific perspective, by studying how it modulates attention. Being mindful defines a state characterized by 1-an attention directed to the subjective experience of present moment, 2-an unconditional acceptance of this experience, and 3-the rejection of systematic rationalization in favor of plain awareness. The aim of this study is to investigate whether perceptual salience filters are lowered in a ‘mindful’ condition by exploring the role of being mindful in focused visual attention. Over the past decade, mindfulness therapies have seen a surge in popularity. While the outcomes of these therapies have been widely discussed, the mechanisms whereby meditation affects the brain remain mostly unknown. To explore the role of mindfulness in focused visual attention, we conducted a change blindness experiment on 24 subjects, 12 of them being mindful according to the Freiburg Mindfulness Inventory (FMI) scale. Our results suggest that mindful subjects are less affected by change blindness than non-mindful subjects. Furthermore, EEG measurements performed during the experiments may expose neural correlates specific to the mindful state on P300 evoked potentials. Finally, the analysis of both amplitude and latency caused by the perception of a change over 864 recordings may reveal biomarkers that are typical of this state. The paper concludes by discussing the implications of these results for further research. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=EEG" title="EEG">EEG</a>, <a href="https://publications.waset.org/abstracts/search?q=change%20blindness" title=" change blindness"> change blindness</a>, <a href="https://publications.waset.org/abstracts/search?q=mindfulness" title=" mindfulness"> mindfulness</a>, <a href="https://publications.waset.org/abstracts/search?q=p300" title=" p300"> p300</a>, <a href="https://publications.waset.org/abstracts/search?q=perception" title=" perception"> perception</a>, <a href="https://publications.waset.org/abstracts/search?q=visual%20attention" title=" visual attention"> visual attention</a> </p> <a href="https://publications.waset.org/abstracts/55682/electroencephalogram-study-of-change-blindness-in-mindful-subjects" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/55682.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">257</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">14</span> Maximizing Profit Using Optimal Control by Exploiting the Flexibility in Thermal Power Plants</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Daud%20Mustafa%20Minhas">Daud Mustafa Minhas</a>, <a href="https://publications.waset.org/abstracts/search?q=Raja%20Rehan%20Khalid"> Raja Rehan Khalid</a>, <a href="https://publications.waset.org/abstracts/search?q=Georg%20Frey"> Georg Frey</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The next generation power systems are equipped with abundantly available free renewable energy resources (RES). During their low-cost operations, the price of electricity significantly reduces to a lower value, and sometimes it becomes negative. Therefore, it is recommended not to operate the traditional power plants (e.g. coal power plants) and to reduce the losses. In fact, it is not a cost-effective solution, because these power plants exhibit some shutdown and startup costs. Moreover, they require certain time for shutdown and also need enough pause before starting up again, increasing inefficiency in the whole power network. Hence, there is always a trade-off between avoiding negative electricity prices, and the startup costs of power plants. To exploit this trade-off and to increase the profit of a power plant, two main contributions are made: 1) introducing retrofit technology for state of art coal power plant; 2) proposing optimal control strategy for a power plant by exploiting different flexibility features. These flexibility features include: improving ramp rate of power plant, reducing startup time and lowering minimum load. While, the control strategy is solved as mixed integer linear programming (MILP), ensuring optimal solution for the profit maximization problem. Extensive comparisons are made considering pre and post-retrofit coal power plant having the same efficiencies under different electricity price scenarios. It concludes that if the power plant must remain in the market (providing services), more flexibility reflects direct economic advantage to the plant operator. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=discrete%20optimization" title="discrete optimization">discrete optimization</a>, <a href="https://publications.waset.org/abstracts/search?q=power%20plant%20flexibility" title=" power plant flexibility"> power plant flexibility</a>, <a href="https://publications.waset.org/abstracts/search?q=profit%20maximization" title=" profit maximization"> profit maximization</a>, <a href="https://publications.waset.org/abstracts/search?q=unit%20commitment%20model" title=" unit commitment model"> unit commitment model</a> </p> <a href="https://publications.waset.org/abstracts/99691/maximizing-profit-using-optimal-control-by-exploiting-the-flexibility-in-thermal-power-plants" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/99691.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">143</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">13</span> Evaluation of Knowledge and Acceptance of Food Irradiated by Individual from Food Bank of Brazil</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Juliana%20Altavista%20Sagretti%20Gallo">Juliana Altavista Sagretti Gallo</a>, <a href="https://publications.waset.org/abstracts/search?q=Susy%20Frey%20Sabato"> Susy Frey Sabato</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Despite the poverty in the world, a third of all food produced in the world is wasted. FAO, the United Nations Organization of Agriculture and Food, points out the need to combine actions and new technologies to combat hunger and waste in contrast to the high production of food in the world. The energy of ionizing radiation in food brought many positive results, such as increased validity and insect infestation control. The food banks are organizations that act at various points of the food chain to collect and distribute food to the needy. So, the aim of this study was to initiate a partnership between irradiation and the food bank through the development of a questionnaire to evaluate and disseminate the knowledge and acceptance of individuals in the food bank in Brazil. Also, this study aimed to standardize a basis questionnaire for future research assessment of irradiated foods. For the construction of the questionnaire as a measuring instrument, a comprehensive and rigorous literature review was made. It's covered qualitative research, questionnaires, sensory evaluation, and food irradiated. Three stages of pre - tests were necessary, and related fields of experts were consulted. As a result, the questionnaire has three parts, personal issues, assertive issues and questions of multiple choices and finally an informative question. The questionnaire was applied in Ceagesp food bank in the biggest center of food in Brazil. Conclusions. 30 % of participants of Ceagesp bank had already heard of the Food irradiation but did not know about the mechanism, so they rejected the idea to associate with radioactivity and danger. The video showed in the last question and application of the questionnaire disseminated the idea of security. All individuals declare understand the goal of treatment and accept buy and consume irradiated food after them. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bank%20of%20food" title="bank of food">bank of food</a>, <a href="https://publications.waset.org/abstracts/search?q=questionary" title=" questionary"> questionary</a>, <a href="https://publications.waset.org/abstracts/search?q=irradiated%20food" title=" irradiated food"> irradiated food</a>, <a href="https://publications.waset.org/abstracts/search?q=acceptance%20of%20irradiated%20food" title=" acceptance of irradiated food"> acceptance of irradiated food</a> </p> <a href="https://publications.waset.org/abstracts/67968/evaluation-of-knowledge-and-acceptance-of-food-irradiated-by-individual-from-food-bank-of-brazil" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/67968.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">323</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">12</span> Questioning the Relationship Between Young People and Fake News Through Their Use of Social Media</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Marion%20Billard">Marion Billard</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper will focus on the question of the real relationship between young people and fake news. Fake news is one of today’s main issues in the world of information and communication. Social media and its democratization helped to spread false information. According to traditional beliefs, young people are more inclined to believe what they read through social media. But, the individuals concerned, think that they are more inclined to make a distinction between real and fake news. This phenomenon is due to their use of the internet and social media from an early age. During the 2016 and 2017 French and American presidential campaigns, the term fake news was in the mouth of the entire world and became a real issue in the field of information. While young people were informing themselves with newspapers or television until the beginning of the ’90s, Gen Z (meaning people born between 1997 and 2010), has always been immersed in this world of fast communication. They know how to use social media from a young age and the internet has no secret for them. Today, despite the sporadic use of traditional media, young people tend to turn to their smartphones and social networks such as Instagram or Twitter to stay abreast of the latest news. The growth of social media information led to an “ambient journalism”, giving access to an endless quantity of information. Waking up in the morning, young people will see little posts with short texts supplying the essential of the news, without, for the most, many details. As a result, impressionable people are not able to do a distinction between real media, and “junk news” or Fake News. This massive use of social media is probably explained by the inability of the youngsters to find connections between the communication of the traditional media and what they are living. The question arises if this over-confidence of the young people in their ability to distinguish between accurate and fake news would not make it more difficult for them to examine critically the information. Their relationship with media and fake news is more complex than popular opinion. Today’s young people are not the master in the quest for information, nor inherently the most impressionable public on social media. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fake%20news" title="fake news">fake news</a>, <a href="https://publications.waset.org/abstracts/search?q=youngsters" title=" youngsters"> youngsters</a>, <a href="https://publications.waset.org/abstracts/search?q=social%20media" title=" social media"> social media</a>, <a href="https://publications.waset.org/abstracts/search?q=information" title=" information"> information</a>, <a href="https://publications.waset.org/abstracts/search?q=generation" title=" generation"> generation</a> </p> <a href="https://publications.waset.org/abstracts/144465/questioning-the-relationship-between-young-people-and-fake-news-through-their-use-of-social-media" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/144465.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">161</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">11</span> Development of Highly Repellent Silica Nanoparticles Treatment for Protection of Bio-Based Insulation Composite Material </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nadia%20Sid">Nadia Sid</a>, <a href="https://publications.waset.org/abstracts/search?q=Alan%20Taylor"> Alan Taylor</a>, <a href="https://publications.waset.org/abstracts/search?q=Marion%20Bourebrab"> Marion Bourebrab</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The construction sector is on the critical path to decarbonise the European economy by 2050. In order to achieve this objective it must enable reducing its CO2 emission by 90% and its energy consumption by as much as 50%. For this reason, a new class of low environmental impact construction materials named “eco-material” are becoming increasingly important in the struggle against climate change. A European funded collaborative project ISOBIO coordinated by TWI is aimed at taking a radical approach to the use of bio-based aggregates to create novel construction materials that are usable in high volume in using traditional methods, as well as developing markets such as exterior insulation of existing house stocks. The approach taken for this project is to use finely chopped material protected from bio-degradation through the use of functionalized silica nanoparticles. TWI is exploring the development of novel inorganic-organic hybrid nano-materials, to be applied as a surface treatment onto bio-based aggregates. These nanoparticles are synthesized by sol-gel processing and then functionalised with silanes to impart multifunctionality e.g. hydrophobicity, fire resistance and chemical bonding between the silica nanoparticles and the bio-based aggregates. This talk will illustrate the approach taken by TWI to design the functionalized silica nanoparticles by using a material-by-design approach. The formulation and synthesize process will be presented together with the challenges addressed by those hybrid nano-materials. The results obtained with regards to the water repellence and fire resistance will be displayed together with preliminary public results of the ISOBIO project.

Mincle receptor activation promotes the production of these substances by increasing the transcription of inflammatory cytokines and chemokines. Cytokines, which play an important role in the initiation and maintenance of such inflammatory pain diseases, have a significant effect on sensory neurons in addition to their enhancement and inhibitory effects on immune and inflammatory cells as mediators of cell interaction. Glial cells in the central nervous system play a critical role in development and maintenance of chronic pain states. Microglia are tissue-resident macrophages in the central nervous system, and belong to a group of mononuclear phagocytes. In the central nervous system, mincle receptor is present in neurons and glial cells of the brain.This study was performed to identify the Mincle receptor in the spinal cord and to investigate the effect of Mincle receptor activation on nociception and the changes of microglia. Materials and Methods: C-type lectins(Mincle) was identified in spinal cord of Male Sprague–Dawley rats. Then, mincle receptor ligand (TDB), via an intrathecal catheter. Mechanical allodynia was measured using von Frey test to evaluate the effect of intrathecal injection of TDB. Result: The present investigation shows that the intrathecal administration of TDB in the rat produces a reliable and quantifiable mechanical hyperalgesia. In addition, The mechanical hyperalgesia after TDB injection gradually developed over time and remained until 10 days. Mincle receptor is identified in the spinal cord, mainly expressed in neuronal cells, but not in microglia or astrocyte. These results suggest that activation of mincle receptor pathway in neurons plays an important role in inducing activation of microglia and inducing mechanical allodynia. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=mincle" title="mincle">mincle</a>, <a href="https://publications.waset.org/abstracts/search?q=spinal%20cord" title=" spinal cord"> spinal cord</a>, <a href="https://publications.waset.org/abstracts/search?q=pain" title=" pain"> pain</a>, <a href="https://publications.waset.org/abstracts/search?q=microglia" title=" microglia"> microglia</a> </p> <a href="https://publications.waset.org/abstracts/79571/microglia-activity-and-induction-of-mechanical-allodynia-after-mincle-receptor-ligand-injection-in-rat-spinal-cord" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/79571.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">159</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">9</span> Object Detection in Digital Images under Non-Standardized Conditions Using Illumination and Shadow Filtering</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Waqqas-ur-Rehman%20Butt">Waqqas-ur-Rehman Butt</a>, <a href="https://publications.waset.org/abstracts/search?q=Martin%20Servin"> Martin Servin</a>, <a href="https://publications.waset.org/abstracts/search?q=Marion%20Pause"> Marion Pause</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In recent years, object detection has gained much attention and very encouraging research area in the field of computer vision. The robust object boundaries detection in an image is demanded in numerous applications of human computer interaction and automated surveillance systems. Many methods and approaches have been developed for automatic object detection in various fields, such as automotive, quality control management and environmental services. Inappropriately, to the best of our knowledge, object detection under illumination with shadow consideration has not been well solved yet. Furthermore, this problem is also one of the major hurdles to keeping an object detection method from the practical applications. This paper presents an approach to automatic object detection in images under non-standardized environmental conditions. A key challenge is how to detect the object, particularly under uneven illumination conditions. Image capturing conditions the algorithms need to consider a variety of possible environmental factors as the colour information, lightening and shadows varies from image to image. Existing methods mostly failed to produce the appropriate result due to variation in colour information, lightening effects, threshold specifications, histogram dependencies and colour ranges. To overcome these limitations we propose an object detection algorithm, with pre-processing methods, to reduce the interference caused by shadow and illumination effects without fixed parameters. We use the Y CrCb colour model without any specific colour ranges and predefined threshold values. The segmented object regions are further classified using morphological operations (Erosion and Dilation) and contours. Proposed approach applied on a large image data set acquired under various environmental conditions for wood stack detection. Experiments show the promising result of the proposed approach in comparison with existing methods. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=image%20processing" title="image processing">image processing</a>, <a href="https://publications.waset.org/abstracts/search?q=illumination%20equalization" title=" illumination equalization"> illumination equalization</a>, <a href="https://publications.waset.org/abstracts/search?q=shadow%20filtering" title=" shadow filtering"> shadow filtering</a>, <a href="https://publications.waset.org/abstracts/search?q=object%20detection" title=" object detection"> object detection</a> </p> <a href="https://publications.waset.org/abstracts/77157/object-detection-in-digital-images-under-non-standardized-conditions-using-illumination-and-shadow-filtering" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/77157.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">216</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">8</span> An Interpretative Phenomenological Analysis of the Death Practices and Rituals of the Isneg People in Apayao</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ivy%20Angelique%20Malit">Ivy Angelique Malit</a>, <a href="https://publications.waset.org/abstracts/search?q=Marion%20Nicole%20Dela%20Vega"> Marion Nicole Dela Vega</a>, <a href="https://publications.waset.org/abstracts/search?q=Marjorie%20Mae%20Mendoza"> Marjorie Mae Mendoza</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Death practices and rituals of the Philippines is rich with facts about our history mostly on our beliefs of the afterlife before the arrival of the western culture which is still being practiced by the indigenous people of the Philippines. The death practices and rituals are acts of showing the inner thoughts, and feelings towards the person who died. The meanings behind those practices and rituals become the reason why the indigenous people still treasure these death practices and rituals as a part of their culture. This study seeks to know the experiences of the death practices and rituals of one of the Indigenous groups in Apayao, the Isnegs and the meaning of those experiences. The researchers aimed to look at it on a psychological lens. In which the researchers aim (1) to know their experiences of their death practices from the perspective of their thoughts, feelings and actions, and (2) to seek the meaning behind their death rituals. The design used in the research is a qualitative design and Interpretative Phenomenological Analysis. The participants were gathered by using purposive sampling. The researchers gathered the data from a form of a semi-structured interview with guide questions. The researchers used Thematic Analysis to analyze the verbatim transcriptions from the interview. The experiences of death practices and rituals of the Isneg people have been presented in the aspects of their thoughts, feelings and behavior. The experiences were presented with 7 superordinate themes namely, (1) Refusal of Reality (2) Feelings of mixed emotions (3) Oblivious Acts of the participants (4) Conflict with self and culture (5) Negative thinking of the participants (6) Process of Acceptance (8) Act of Love. The make meaning behind the death practices and rituals of the Isneg people have been presented with 2 superordinate themes, (1) Act of Respect and (2) Act of Loyalty. The results of the research show that the experiences and meaning behind their death practices and burials were being based more by their own beliefs. In their culture, which has been passed through by their ancestors and becomes the foundation of their beliefs and their newly found religion which was introduced by the travelling missionaries. Doing those death practices and rituals is their way to show their affections, like respect and loyalty towards the person who died. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=death%20practices" title="death practices">death practices</a>, <a href="https://publications.waset.org/abstracts/search?q=interpretative%20phenomenological%20analysis" title=" interpretative phenomenological analysis"> interpretative phenomenological analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=isneg%20people" title=" isneg people"> isneg people</a>, <a href="https://publications.waset.org/abstracts/search?q=rituals" title=" rituals"> rituals</a>, <a href="https://publications.waset.org/abstracts/search?q=theory%20of%20grieving" title=" theory of grieving"> theory of grieving</a> </p> <a href="https://publications.waset.org/abstracts/63083/an-interpretative-phenomenological-analysis-of-the-death-practices-and-rituals-of-the-isneg-people-in-apayao" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/63083.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">254</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">7</span> NMR-Based Metabolomic Study of Antimalarial Plant Species Used Traditionally by Vha-Venda People in Limpopo Province, South Africa</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Johanna%20Bapela">Johanna Bapela</a>, <a href="https://publications.waset.org/abstracts/search?q=Heino%20Heyman"> Heino Heyman</a>, <a href="https://publications.waset.org/abstracts/search?q=Marion%20Meyer"> Marion Meyer</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Regardless of the significant advances accomplished in reducing the burden of malaria and other tropical diseases in recent years, malaria remains a major cause of mortality in endemic countries. This is especially the case in sub-Saharan Africa where 99% of the estimated global malaria deaths occurs on an annual basis. The emergence of resistant Plasmodium species and the lack of diversified chemotherapeutic agents provide the rationale for bioprospecting for antiplasmodial scaffolds. Crude extracts from twenty indigenous antimalarial plant species were screened for antimalarial activity and then subjected to 1H NMR-based metabolomic analysis. Ten plant extracts exhibited significant in vitro antiplasmodial activity (IC50 ≤ 5 µg/ml). The Principal Component Analysis (PCA) of the acquired 1H NMR spectra could not separate the analyzed plant extracts according to the detected antiplasmodial bioactivity. Application of supervised Orthogonal Projections to Latent Structures–Discriminant Analysis (OPLS-DA) to the 1H NMR profiles resulted in a discrimination pattern that could be correlated to bioactivity. A contribution plot generated from the OPLS-DA scoring plot illustrated the classes of compounds responsible for the observed grouping. Given the preliminary in vitro results, Tabernaemontana elegans Stapf. (Apocynaceae) and Vangueria infausta Burch. subsp. infausta (Rubiaceae) were subjected to further phytochemical investigations. Two indole alkaloids, dregamine and tabernaemontanine possessing antiplasmodial activity were isolated from T. elegans. Two compounds were isolated from V. infausta subsp. infausta and identified as friedelin (IC50 = 3.01 µg/ml) and morindolide (IC50 = 18.5 µg/ml). While these compounds have been previously identified, this is the first account of their occurrence in the genus Vangueria and their antiplasmodial activity. Based on the results of the study, metabolomics can be used to globally identify classes of plant secondary metabolites that are responsible for antiplasmodial activity. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ethnopharmacology" title="ethnopharmacology">ethnopharmacology</a>, <a href="https://publications.waset.org/abstracts/search?q=Malaria" title=" Malaria"> Malaria</a>, <a href="https://publications.waset.org/abstracts/search?q=medicinal%20plants" title=" medicinal plants"> medicinal plants</a>, <a href="https://publications.waset.org/abstracts/search?q=metabolomics" title=" metabolomics"> metabolomics</a> </p> <a href="https://publications.waset.org/abstracts/55170/nmr-based-metabolomic-study-of-antimalarial-plant-species-used-traditionally-by-vha-venda-people-in-limpopo-province-south-africa" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/55170.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">341</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">6</span> Everolimus Loaded Polyvinyl Alcohol Microspheres for Sustained Drug Delivery in the Treatment of Subependymal Giant Cell Astrocytoma</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lynn%20Louis">Lynn Louis</a>, <a href="https://publications.waset.org/abstracts/search?q=Bor%20Shin%20Chee"> Bor Shin Chee</a>, <a href="https://publications.waset.org/abstracts/search?q=Marion%20McAfee"> Marion McAfee</a>, <a href="https://publications.waset.org/abstracts/search?q=Michael%20Nugent"> Michael Nugent</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This article aims to develop a sustained release formulation of microspheres containing the mTOR inhibitor Everolimus (EVR) using Polyvinyl alcohol (PVA) to enhance the bioavailability of the drug and to overcome poor solubility characteristics of Everolimus. This paper builds on recent work in the manufacture of microspheres using the sessile droplet technique by freezing the polymer-drug solution by suspending the droplets into pre-cooled ethanol vials immersed in liquid nitrogen. The spheres were subjected to 6 freezing cycles and 3 freezing cycles with thawing to obtain proper geometry, prevent aggregation, and achieve physical cross-linking. The prepared microspheres were characterised for surface morphology by SEM, where a 3-D porous structure was observed. The in vitro release studies showed a 62.17% release over 12.5 days, indicating a sustained release due to good encapsulation. This result is comparatively much more than the 49.06% release achieved within 4 hours from the solvent cast Everolimus film as a control with no freeze-thaw cycles performed. The solvent cast films were made in this work for comparison. A prolonged release of Everolimus using a polymer-based drug delivery system is essential to reach optimal therapeutic concentrations in treating SEGA tumours without systemic exposure. These results suggest that the combination of PVA and Everolimus via a rheological synergism enhanced the bioavailability of the hydrophobic drug Everolimus. Physical-chemical characterisation using DSC and FTIR analysis showed compatibility of the drug with the polymer, and the stability of the drug was maintained owing to the high molecular weight of the PVA. The obtained results indicate that the developed PVA/EVR microsphere is highly suitable as a potential drug delivery system with improved bioavailability in treating Subependymal Giant cell astrocytoma (SEGA). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=drug%20delivery%20system" title="drug delivery system">drug delivery system</a>, <a href="https://publications.waset.org/abstracts/search?q=everolimus" title=" everolimus"> everolimus</a>, <a href="https://publications.waset.org/abstracts/search?q=freeze-thaw%20cycles" title=" freeze-thaw cycles"> freeze-thaw cycles</a>, <a href="https://publications.waset.org/abstracts/search?q=polyvinyl%20alcohol" title=" polyvinyl alcohol"> polyvinyl alcohol</a> </p> <a href="https://publications.waset.org/abstracts/151445/everolimus-loaded-polyvinyl-alcohol-microspheres-for-sustained-drug-delivery-in-the-treatment-of-subependymal-giant-cell-astrocytoma" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/151445.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">127</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5</span> Intrathecal: Not Intravenous Administration of Evans Blue Reduces Pain Behavior in Neuropathic Rats</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kun%20Hua%20O.">Kun Hua O.</a>, <a href="https://publications.waset.org/abstracts/search?q=Dong%20Woon%20Kim"> Dong Woon Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Won%20Hyung%20Lee"> Won Hyung Lee</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: Neuropathic pain induced by spinal or peripheral nerve injury is highly resistant to common painkillers, nerve blocks, and other pain management approaches. Recently, several new therapeutic drug candidates have been developed to control neuropathic pain. In this study, we used the spinal nerve L5 ligation (SNL) model to investigate the ability of intrathecal or intravenous Evans blue to decrease pain behavior and to study the relationship between Evans blue and the neural structure of pain transmission. Method: Neuropathic pain (allodynia) of the left hind paw was induced by unilateral SNL in Sprague-Dawley rats(n=10) in each group. Evans blue (5, 15, 50μg/10μl) or phosphate buffer saline(PBS,10μl) was injected intrathecally at 3days post-ligation or intravenously(1mg/200 μl) 3days and 5days post-ligation . Mechanical sensitivity was assessed using Von Frey filaments at 3 days post-ligation and at 2 hours, days 1, 2, 3, 5,7 after intrathecal Evans blue injection, and on days 2, 4, 7, and 11 at 14 days after intravenous injection. In the intrathecal group, microglia and glutaminergic neurons in the dorsal horn and VNUT(vesicular nucleotide transporter) in the dorsal root ganglia were tested to evaluate co-staining with Evans blue. The experimental procedures were performed in accordance with the animal care guideline of the Korean Academy of Medical Science(Animal ethic committee of Chungnam National University Hospital: CNUH-014-A0005-1). Results: Tight ligation of the L5 spinal nerve induced allodynia in the left hind paw 3 days post-ligation. Intrathecal Evans blue most significantly(P＜0.001) alleviated allodynia at 2 days after intrathecal, but not an intravenous injection. Glutaminergic neurons in the dorsal horn and VNUT in the dorsal root ganglia were co-stained with Evans blue. On the other hand, microglia in the dorsal horn were partially co-stained with Evans blue. Conclusion: We confirmed that Evans blue might have an analgesic effect through the central nervous system, not another system in neuropathic pain of the SNL animal model. These results suggest Evans blue may be a potential new drug for the treatment of chronic pain.

Most of them take College Algebra, and to continue their studies, they need to succeed in this course. Different pedagogical strategies are employed to promote the success of our students. There is, of course, the Traditional Method of teaching- lecture, examples, problems for students to solve. The Emporium Model, another pedagogical approach, replaces traditional lectures with a learning resource center model featuring interactive software and on-demand personalized assistance. This presentation will compare these two methods of pedagogy and the study done with its results on this comparison. Math is the foundation for science, technology, and engineering. Its work is generally used in STEM to find patterns in data. These patterns can be used to test relationships, draw general conclusions about data, and model the real world. In STEM, solutions to problems are analyzed, reasoned, and interpreted using math abilities in a assortment of real-world scenarios. This presentation will examine specific examples of how math is used in the different STEM disciplines. Math becomes practical in science when it is used to model natural and artificial experiments to identify a problem and develop a solution for it. As we analyze data, we are using math to find the statistical correlation between the cause of an effect. Scientists who use math include the following: data scientists, scientists, biologists and geologists. Without math, most technology would not be possible. Math is the basis of binary, and without programming, you just have the hardware. Addition, subtraction, multiplication, and division is also used in almost every program written. Mathematical algorithms are inherent in software as well. Mechanical engineers analyze scientific data to design robots by applying math and using the software. Electrical engineers use math to help design and test electrical equipment. They also use math when creating computer simulations and designing new products. Chemical engineers often use mathematics in the lab.

Therefore, the feeling of pain is not only a personal experience and is affected by social background; therefore, it involves extensive systems of signals. The challenges in emotional and sentimental dimensions of pain originate from scientific medicine (i.e., the dominant theory is also referred to as the specificity theory); however, this theory has accepted some alterations by emerging physiology. Then, Von Frey suggested the theory of cutaneous senses (i.e., Muller’s concept: the common sensation of combined four major skin receptors leading to a proper sensation) 50 years after the specificity theory. The pain pathway was composed of spinothalamic tracts and thalamus with an inhibitory effect on the cortex. Pain is referred to as a series of unique experiences with various reasons and qualities. Despite the gate control theory, the biological aspect overcomes the social aspect. Vrancken provided a more extensive definition of pain and found five approaches: Somatico-technical, dualistic body-oriented, behaviorist, phenomenological, and consciousness approaches. The Western model combined physical, emotional, and existential aspects of the human body. On the other hand, Kotarba felt confused about the basic origins of chronic pain. Freund demonstrated and argued with Durkhemian about the sociological approach to emotions. Lynch provided a piece of evidence about the correlation between cardiovascular disease and emotionally life-threatening occurrences. Helman supposed a distinction between private and public pain. Conclusion: The consideration of the emotional aspect of pain could lead to effective, emotional, and social responses to pain. On the contrary, the theory of embodiment is based on the sociological view of health and illness. Social epidemiology shows an imbalanced distribution of health, illness, and disability among various social groups. The social support and socio-cultural level can result in several types of pain. It means the status of athletes might define their pain experiences. Gender is one of the important contributing factors affecting the type of pain (i.e., females are more likely to seek health services for pain relief.) Chronic non-cancer pain (CNCP) has become a serious public health issue affecting more than 70 million people globally. CNCP is a serious public health issue which is caused by the lack of awareness about chronic pain management among the general population. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=pain" title="pain">pain</a>, <a href="https://publications.waset.org/abstracts/search?q=sociology" title=" sociology"> sociology</a>, <a href="https://publications.waset.org/abstracts/search?q=sociological" title=" sociological"> sociological</a>, <a href="https://publications.waset.org/abstracts/search?q=body" title=" body"> body</a> </p> <a href="https://publications.waset.org/abstracts/168773/a-brief-review-on-the-relationship-between-pain-and-sociology" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/168773.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">70</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2</span> Benefits of The ALIAmide Palmitoyl-Glucosamine Co-Micronized with Curcumin for Osteoarthritis Pain: A Preclinical Study </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Enrico%20Gugliandolo">Enrico Gugliandolo</a>, <a href="https://publications.waset.org/abstracts/search?q=Salvatore%20Cuzzocrea"> Salvatore Cuzzocrea</a>, <a href="https://publications.waset.org/abstracts/search?q=Rosalia%20Crupi"> Rosalia Crupi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Osteoarthritis (OA) is one of the most common chronic pain conditions in dogs and cats. OA pain is currently viewed as a mixed phenomenon involving both inflammatory and neuropathic mechanisms at the peripheral (joint) and central (spinal and supraspinal) levels. Oxidative stress has been implicated in OA pain. Although nonsteroidal anti-inflammatory drugs are commonly prescribed for OA pain, they should be used with caution in pets because of adverse effects in the long term and controversial efficacy on neuropathic pain. An unmet need remains for safe and effective long-term treatments for OA pain. Palmitoyl-glucosamine (PGA) is an analogue of the ALIAamide palmitoylethanolamide, i.e., a body’s own endocannabinoid-like compound playing a sentinel role in nociception. PGA, especially in the micronized formulation, was shown safe and effective in OA pain. The aim of this study was to investigate the effect of a co-micronized formulation of PGA with the natural antioxidant curcumin (PGA-cur) on OA pain. Ten Sprague-Dawley male rats were used for each treatment group. The University of Messina Review Board for the care and use of animals authorized the study. On day 0, rats were anesthetized (5.0% isoflurane in 100% O2) and received intra-articular injection of MIA (3 mg in 25 μl saline) in the right knee joint, with the left being injected an equal volume of saline. Starting the third day after MIA injection, treatments were administered orally three times per week for 21 days, at the following doses: PGA 20 mg/kg, curcumin 10 mg/kg, PGA-cur (2:1 ratio) 30 mg/kg. On day 0 and 3, 7, 14 and 21 days post-injection, mechanical allodynia was measured using a dynamic plantar Von Frey hair aesthesiometer and expressed as paw withdrawal threshold (PWT) and latency (PWL). Motor functional recovery of the rear limb was evaluated on the same time points by walking track analysis using the sciatic functional index. On day 21 post-MIA injection, the concentration of the following inflammatory and nociceptive mediators was measured in serum using commercial ELISA kits: tumor necrosis factor alpha (TNF-α), interleukin-1 beta (IL-1β), nerve growth factor (NGF) and matrix metalloproteinase-1-3-9 (MMP-1, MMP-3, MMP-9). The results were analyzed by ANOVA followed by Bonferroni post-hoc test for multiple comparisons. Micronized PGA reduced neuropathic pain, as shown by the significant higher PWT and PWL values compared to vehicle group (p < 0.0001 for all the evaluated time points). The effect of PGA-cur was superior at all time points (p < 0.005). PGA-cur restored motor function already on day 14 (p < 0.005), while micronized PGA was effective a week later (D21). MIA-induced increase in the serum levels of all the investigated mediators was inhibited by PGA-cur (p < 0.01). PGA was also effective, except on IL-1 and MMP-3. Curcumin alone was inactive in all the experiments at any time point. The encouraging results suggest that PGA-cur may represent a valuable option in OA pain management and warrant further confirmation in well-powered clinical trials. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ALIAmides" title="ALIAmides">ALIAmides</a>, <a href="https://publications.waset.org/abstracts/search?q=curcumin" title=" curcumin"> curcumin</a>, <a href="https://publications.waset.org/abstracts/search?q=osteoarthritis" title=" osteoarthritis"> osteoarthritis</a>, <a href="https://publications.waset.org/abstracts/search?q=palmitoyl-glucosamine" title=" palmitoyl-glucosamine"> palmitoyl-glucosamine</a> </p> <a href="https://publications.waset.org/abstracts/128320/benefits-of-the-aliamide-palmitoyl-glucosamine-co-micronized-with-curcumin-for-osteoarthritis-pain-a-preclinical-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/128320.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">115</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1</span> Characterization of Thin Woven Composites Used in Printed Circuit Boards by Combining Numerical and Experimental Approaches</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gautier%20Girard">Gautier Girard</a>, <a href="https://publications.waset.org/abstracts/search?q=Marion%20Martiny"> Marion Martiny</a>, <a href="https://publications.waset.org/abstracts/search?q=Sebastien%20Mercier"> Sebastien Mercier</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamad%20Jrad"> Mohamad Jrad</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamed-Slim%20Bahi"> Mohamed-Slim Bahi</a>, <a href="https://publications.waset.org/abstracts/search?q=Laurent%20Bodin"> Laurent Bodin</a>, <a href="https://publications.waset.org/abstracts/search?q=Francois%20Lechleiter"> Francois Lechleiter</a>, <a href="https://publications.waset.org/abstracts/search?q=David%20Nevo"> David Nevo</a>, <a href="https://publications.waset.org/abstracts/search?q=Sophie%20Dareys"> Sophie Dareys</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Reliability of electronic devices has always been of highest interest for Aero-MIL and space applications. In any electronic device, Printed Circuit Board (PCB), providing interconnection between components, is a key for reliability. During the last decades, PCB technologies evolved to sustain and/or fulfill increased original equipment manufacturers requirements and specifications, higher densities and better performances, faster time to market and longer lifetime, newer material and mixed buildups. From the very beginning of the PCB industry up to recently, qualification, experiments and trials, and errors were the most popular methods to assess system (PCB) reliability. Nowadays OEM, PCB manufacturers and scientists are working together in a close relationship in order to develop predictive models for PCB reliability and lifetime. To achieve that goal, it is fundamental to characterize precisely base materials (laminates, electrolytic copper, …), in order to understand failure mechanisms and simulate PCB aging under environmental constraints by means of finite element method for example. The laminates are woven composites and have thus an orthotropic behaviour. The in-plane properties can be measured by combining classical uniaxial testing and digital image correlation. Nevertheless, the out-of-plane properties cannot be evaluated due to the thickness of the laminate (a few hundred of microns). It has to be noted that the knowledge of the out-of-plane properties is fundamental to investigate the lifetime of high density printed circuit boards. A homogenization method combining analytical and numerical approaches has been developed in order to obtain the complete elastic orthotropic behaviour of a woven composite from its precise 3D internal structure and its experimentally measured in-plane elastic properties. Since the mechanical properties of the resin surrounding the fibres are unknown, an inverse method is proposed to estimate it. The methodology has been applied to one laminate used in hyperfrequency spatial applications in order to get its elastic orthotropic behaviour at different temperatures in the range [-55°C; +125°C]. Next; numerical simulations of a plated through hole in a double sided PCB are performed. Results show the major importance of the out-of-plane properties and the temperature dependency of these properties on the lifetime of a printed circuit board.
