processes in sports medicine and physiotherapy. Often it is used to sensorimotor skills of lower limbs by athletes. The aim of the study was to determine the effect of the application of muscle Kinesiology Taping to feel the position setting in motion the joint active. Material and methods: The study involved 50 healthy people between 18 and 30 years of age, 30 men and 20 women (mean age 23.24 years). The participants were divided into two groups. The study group was qualified for Kinesiology Taping application (muscle application, type Y, for quadriceps femoris muscle), while the remaining people used the application made of plaster (placebo group). Testing was performed prior to applying taping, with the applied application (after 30 minutes), then 24 hours after wearing, and after removing the tape. Each evaluated joint position sense - Error of Active Reproduction of Joint Position. Results: The survey revealed no significant differences in measurement between the study group and the placebo group (p> 0.05). No significant differences in time taking into account all four measurements in the group with the applied CT application, which was supported by pairs (p> 0.05). Also in the placebo group showed no significant differences over time (p> 0.05). There was no significant difference between the errors committed in the direction of flexion and extension. Conclusions: 1. Application muscle Kinesiology Taping had no significant effect on the knee joint proprioception. Its use in order to improve sensorimotor seems therefore unjustified. 2. There are no differences between applications Kinesiology Taping and placebo indicates that the clinical effect of stretch tape is minimal or absent. 3. The results are the basis for the continuation of prospective, randomized trials of numerous and study group. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=joint%20position%20sense" title="joint position sense">joint position sense</a>, <a href="https://publications.waset.org/abstracts/search?q=kinesiology%20taping" title=" kinesiology taping"> kinesiology taping</a>, <a href="https://publications.waset.org/abstracts/search?q=knee%20joint" title=" knee joint"> knee joint</a>, <a href="https://publications.waset.org/abstracts/search?q=proprioception" title=" proprioception"> proprioception</a> </p> <a href="https://publications.waset.org/abstracts/48228/assessment-of-the-impact-of-the-application-of-kinesiology-taping-on-joint-position-sense-in-knee-joint" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/48228.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">403</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> Assessment of Influence of Short-Lasting Whole-Body Vibration on the Proprioception of Lower Limbs</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sebastian%20W%C3%B3jtowicz">Sebastian Wójtowicz</a>, <a href="https://publications.waset.org/abstracts/search?q=Anna%20Mosio%C5%82ek"> Anna Mosiołek</a>, <a href="https://publications.waset.org/abstracts/search?q=Anna%20S%C5%82upik"> Anna Słupik</a>, <a href="https://publications.waset.org/abstracts/search?q=Zbigniew%20Wro%C5%84ski"> Zbigniew Wroński</a>, <a href="https://publications.waset.org/abstracts/search?q=Dariusz%20Bia%C5%82oszewski"> Dariusz Białoszewski</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: In whole-body vibration (WBV) high-frequency mechanical stimuli is generated by a vibration plate and is transferred through bone, muscle and connective tissues to the whole body. The research has shown that the implementation of a vibration plate training over a long period of time leads to improvement of neuromuscular facilitation, especially in afferent neural pathways, which are responsible for the conduction of vibration and proprioceptive stimuli, muscle function, balance, and proprioception. The vibration stimulus is suggested to briefly inhibit the conduction of afferent signals from proprioceptors and may hinder the maintenance of body balance. The purpose of this study was to evaluate the result of a single set of exercises connected with whole-body vibration on the proprioception. Material and Methods: The study enrolled 60 people aged 19-24 years. These individuals were divided into a test group (group A) and a control group (group B). Both groups consisted of 30 persons and performed the same set of exercises on a vibration plate. The following vibration parameters: frequency of 20Hz and amplitude of 3mm, were used in the group A. The vibration plate was turned off while the control group did their exercises. All participants performed six dynamic 30-seconds-long exercises with a 60-second resting period between them. Large muscle groups of the trunk, pelvis, and lower limbs were involved while taking the exercises. The results were measured before and immediately after the exercises. The proprioception of lower limbs was measured in a closed kinematic chain using a Humac 360®. Participants were instructed to perform three squats with biofeedback in a defined range of motion. Then they did three squats without biofeedback which were measured. The final result was the average of three measurements. Statistical analysis was performed using Statistica 10.0 PL software. Results: There were no significant differences between the groups, both before and after the exercise (p > 0.05). The proprioception did not change in both the group A and the group B. Conclusions: 1. Deterioration in proprioception was not observed immediately after the vibration stimulus. This suggests that vibration-induced blockage of proprioceptive stimuli conduction can only have a short-lasting effect occurring only in the presence of the vibration stimulus. 2. Short-term use of vibration seems to be safe for patients with proprioceptive impairment due to the fact that the treatment does not decrease proprioception. 3. There is a need for supplementing the results with evaluation of proprioception while vibration stimuli are being applied. Moreover, the effects of vibration parameters used in the exercises should be evaluated. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=joint%20position%20sense" title="joint position sense">joint position sense</a>, <a href="https://publications.waset.org/abstracts/search?q=proprioception" title=" proprioception"> proprioception</a>, <a href="https://publications.waset.org/abstracts/search?q=squat" title=" squat"> squat</a>, <a href="https://publications.waset.org/abstracts/search?q=whole%20body%20vibration" title=" whole body vibration"> whole body vibration</a> </p> <a href="https://publications.waset.org/abstracts/65329/assessment-of-influence-of-short-lasting-whole-body-vibration-on-the-proprioception-of-lower-limbs" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/65329.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">466</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> Assessment of the Impact of Regular Pilates Exercises on Static Balance in Healthy Adult Women: Preliminary Report</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Anna%20S%C5%82upik">Anna Słupik</a>, <a href="https://publications.waset.org/abstracts/search?q=Krzysztof%20Jaworski"> Krzysztof Jaworski</a>, <a href="https://publications.waset.org/abstracts/search?q=Anna%20Mosio%C5%82ek"> Anna Mosiołek</a>, <a href="https://publications.waset.org/abstracts/search?q=Dariusz%20Bia%C5%82oszewski"> Dariusz Białoszewski</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Maintaining the correct body balance is essential in the prevention of falls in the elderly, which is especially important for women because of postmenopausal osteoporosis and the serious consequences of falls. One of the exercise methods which is very popular among adults, and which may affect body balance in a positive way is the pilates method. The aim of the study was to evaluate the effect of regular pilates exercises on the ability to maintain body balance in static conditions in adult healthy women. Material and methods: The study group consisted of 20 healthy women attending pilates twice a week for at least 1 year. The control group consisted of 20 healthy women physically inactive. Women in the age range from 35 to 50 years old without pain in musculoskeletal system or other pain were only qualified to the groups. Body balance was assessed using MatScan VersaTek platform with Sway Analysis Module based on Matscan Clinical 6.7 software. The balance was evaluated under the following conditions: standing on both feet with eyes open, standing on both feet with eyes closed, one-leg standing (separately on the right and left foot) with eyes open. Each test lasted 30 seconds. The following parameters were calculated: estimated size of the ellipse of 95% confidence, the distance covered by the Center of Gravity (COG), the size of the maximum shift in the sagittal and frontal planes and load distribution between the left and right foot, as well as between rear- and forefoot. Results: It was found that there is significant difference between the groups in favor of the study group in the size of the confidence ellipse and maximum shifts of COG in the sagittal plane during standing on both feet, both with the eyes open and closed (p < 0.05). While standing on one leg both on the right and left leg, with eyes opened there was a significant difference in favor of the study group, in terms of the size of confidence ellipse, the size of the maximum shifts in the sagittal and in the frontal plane (p < 0.05). There were no differences between the distribution of load between the right and left foot (standing with both feet), nor between fore- and rear foot (in standing with both feet or one-leg). Conclusions: 1. Static balance in women exercising regularly by pilates method is better than in inactive women, which may in the future prevent falls and their consequences. 2. The observed differences in maintaining balance in frontal plane in one-leg standing may indicate a positive impact of pilates exercises on the ability to maintain global balance in terms of the reduced support surface. 3. Pilates method can be used as a form preventive therapy for all people who are expected to have problems with body balance in the future, for example in chronic neurological disorders or vestibular problems. 4. The results have shown that further prospective randomized research on a larger and more representative group is needed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=balance%20exercises" title="balance exercises">balance exercises</a>, <a href="https://publications.waset.org/abstracts/search?q=body%20balance" title=" body balance"> body balance</a>, <a href="https://publications.waset.org/abstracts/search?q=pilates" title=" pilates"> pilates</a>, <a href="https://publications.waset.org/abstracts/search?q=pressure%20distribution" title=" pressure distribution"> pressure distribution</a>, <a href="https://publications.waset.org/abstracts/search?q=women" title=" women"> women</a> </p> <a href="https://publications.waset.org/abstracts/32536/assessment-of-the-impact-of-regular-pilates-exercises-on-static-balance-in-healthy-adult-women-preliminary-report" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/32536.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">318</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> Applications of Probabilistic Interpolation via Orthogonal Matrices</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Dariusz%20Jacek%20Jak%C3%B3bczak">Dariusz Jacek Jakóbczak</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Mathematics and computer science are interested in methods of 2D curve interpolation and extrapolation using the set of key points (knots).

Conventional CFRPs also have their disadvantages, namely, relatively low electrical conductivity and brittle cracking. To counteract this, a thermoplastic acrylic resin was proposed, which was further modified by the addition of organosilicon compounds and multi-walled carbon nanotubes (MWCNTs). The addition of the organosilicon compounds was aimed at improving the dispersion of the MWCNTs and obtaining good adhesion between the resin and the carbon fibre, where the MWCNTs were used as a conductive filler. In addition, during the fabrication of laminates using the infusion method, thermoplastic nonwovens doped with MWCNTs were placed between the carbon reinforcement layers to achieve a synergistic effect with an increase in electrical and mechanical properties. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=CFRP" title="CFRP">CFRP</a>, <a href="https://publications.waset.org/abstracts/search?q=acrylic%20resin" title=" acrylic resin"> acrylic resin</a>, <a href="https://publications.waset.org/abstracts/search?q=organosilicon%20compounds" title=" organosilicon compounds"> organosilicon compounds</a>, <a href="https://publications.waset.org/abstracts/search?q=mechanical%20properties" title=" mechanical properties"> mechanical properties</a>, <a href="https://publications.waset.org/abstracts/search?q=electrical%20properties" title=" electrical properties"> electrical properties</a> </p> <a href="https://publications.waset.org/abstracts/153127/chemical-and-physical-modification-of-carbon-fiber-reinforced-polymers-based-on-thermoplastic-acrylic-resin" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/153127.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">128</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> Electronic Nose for Monitoring Fungal Deterioration of Stored Rapeseed</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Robert%20Rusinek">Robert Rusinek</a>, <a href="https://publications.waset.org/abstracts/search?q=Marek%20Gancarz"> Marek Gancarz</a>, <a href="https://publications.waset.org/abstracts/search?q=Jolanta%20Wawrzyniak"> Jolanta Wawrzyniak</a>, <a href="https://publications.waset.org/abstracts/search?q=Marzena%20Gawrysiak-Witulska"> Marzena Gawrysiak-Witulska</a>, <a href="https://publications.waset.org/abstracts/search?q=Dariusz%20Wi%C4%85cek"> Dariusz Wiącek</a>, <a href="https://publications.waset.org/abstracts/search?q=Agnieszka%20Nawrocka"> Agnieszka Nawrocka</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Investigations were performed to examine the possibility of using an electronic nose to monitor the development of fungal microflora during the first eighteen days of rapeseed storage. The Cyranose 320 device with polymer-composite sensors was used. Each sample of infected material was divided into three parts, and the degree of spoilage was measured in three ways: analysis of colony forming units (CFU), determination of ergosterol content (ERG), and measurement with the eNose. Principal component analysis (PCA) was performed on the generated patterns of signals, and six groups of different spoilage levels were isolated. The electronic nose with polymer-composite sensors under laboratory conditions distinguished between species of spoiled and unspoiled seeds with 100% accuracy. Despite some minor differences in the CFU and ergosterol content, the electronic nose provided responses correctly corresponding to the level of spoilage with 85% accuracy. Therefore, the main conclusion from the study is that the electronic nose is a promising tool for quick and non-destructive detection of the level of oil seed spoilage.

This phenomenon is used, among others, for the production of liquid floor self-levelling compounds. Alumina cement is several times more expensive than Portland cement and is a component having a significant impact on prices of products manufactured with its use. For the production of liquid floor self-levelling compounds, low-alumina cement containing approximately 40% Al<sub>2</sub>O<sub>3 </sub>is normally used. The aim of the study was to determine the impact of Portland cement with the addition of alumina cement on the basic physical and mechanical properties of cement slurries and mortars. CEM I 42.5R and three types of alumina cement containing 40%, 50% and 70% of Al<sub>2</sub>O<sub>3</sub> were used for the tests. Mixes containing 4%, 6%, 8%, 10% and 12% of different varieties of alumina cement were prepared; for which, the time of initial and final setting, compressive and flexural strength and adhesion to concrete substrate were determined. The analysis of the obtained test results showed that a similar immediate setting effect and clearly better adhesion strength can be obtained using the addition of 6% of high-alumina cement than 12% of low-alumina cement. As the prices of these cements are similar, this can give significant financial savings in the production of liquid floor self-levelling compounds. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=alumina%20cement" title="alumina cement">alumina cement</a>, <a href="https://publications.waset.org/abstracts/search?q=immediate%20setting" title=" immediate setting"> immediate setting</a>, <a href="https://publications.waset.org/abstracts/search?q=compression%20strength" title=" compression strength"> compression strength</a>, <a href="https://publications.waset.org/abstracts/search?q=adhesion%20to%20substrate" title=" adhesion to substrate"> adhesion to substrate</a> </p> <a href="https://publications.waset.org/abstracts/118238/the-impact-of-alumina-cement-on-properties-of-portland-cement-slurries-and-mortars" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/118238.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">152</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> Carbon Fibre Reinforced Polymers Modified with PET-G/MWCNTs Nonwovens</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kamil%20Dydek">Kamil Dydek</a>, <a href="https://publications.waset.org/abstracts/search?q=Szymon%20Demski"> Szymon Demski</a>, <a href="https://publications.waset.org/abstracts/search?q=Kamil%20Majchrowicz"> Kamil Majchrowicz</a>, <a href="https://publications.waset.org/abstracts/search?q=Paulina%20Kozera"> Paulina Kozera</a>, <a href="https://publications.waset.org/abstracts/search?q=Bogna%20Sztorch"> Bogna Sztorch</a>, <a href="https://publications.waset.org/abstracts/search?q=Dariusz%20Brz%C4%85kalski"> Dariusz Brząkalski</a>, <a href="https://publications.waset.org/abstracts/search?q=Zuzanna%20Krawczyk"> Zuzanna Krawczyk</a>, <a href="https://publications.waset.org/abstracts/search?q=Robert%20Przekop"> Robert Przekop</a>, <a href="https://publications.waset.org/abstracts/search?q=Anna%20Boczkowska"> Anna Boczkowska</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Carbon fibre reinforced polymers (CFRPs) are characterized by very high strength and stiffness in relation to their weight. In addition, properties such as corrosion resistance and low thermal expansion allow them to replace traditional materials, i.e., wood or metals, in many industries such as aerospace, automotive, marine, and sports goods. However, CFRPs, have some disadvantages -they have relatively low electrical conductivity and break brittle, which significantly limits their application possibilities. Moreover, conventional CFRPs are usually manufactured based on thermosets, which makes them difficult to recycle. The solution to these drawbacks is the use of the innovative thermoplastic resin (ELIUM from ARKEMA) as a matrix of composites and the modification by introducing into their structure thermoplastic nonwovens based on PET-G with the addition of multi-wall carbon nanotubes (MWCNTs). The acrylic-carbon composites, which were produced by the infusion technique, were tested for mechanical, thermo-mechanical, and electrical properties, and the effect of modifications on their microstructure was studied.

Alan Diehl</a> </p> <p class="card-text"><strong>Abstract:</strong></p> PKR-like ER kinase (PERK) is serine/threonie endoplasmic reticulum (ER) transmembrane kinase activated during ER-stress. PERK can activate signaling pathways known as unfolded protein response (UPR). Attenuation of translation is mediated by PERK via phosphorylation of eukaryotic initiation factor 2α (eIF2α), which is necessary for translation initiation. PERK activation also directly contributes to activation of Nrf2 which regulates expression of anti-oxidant enzymes. An increased phosphorylation of eIF2α has been reported in Alzheimer disease (AD) patient hippocampus, indicating that PERK is activated in this disease. Recent data have revealed activation of PERK signaling in non-Hodgkins lymphomas. Results also revealed that loss of PERK limits mammary tumor cell growth in vitro and in vivo. Consistent with these observations, activation of UPR in vitro increases levels of the amyloid precursor protein (APP), the peptide from which beta-amyloid plaques (AB) fragments are derived. Finally, proteolytic processing of APP, including the cleavages that produce AB, largely occurs in the ER, and localization coincident with PERK activity. Thus, we expect that PERK-dependent signaling is critical for progression of many types of diseases (human cancer, neurodegenerative disease and other). Therefore, modulation of PERK activity may be a useful therapeutic target in the treatment of different diseases that fail to respond to traditional chemotherapeutic strategies, including Alzheimer’s disease. Our goal will be to developed therapeutic modalities targeting PERK activity. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=PERK%20kinase" title="PERK kinase">PERK kinase</a>, <a href="https://publications.waset.org/abstracts/search?q=small%20molecule%20inhibitor" title=" small molecule inhibitor"> small molecule inhibitor</a>, <a href="https://publications.waset.org/abstracts/search?q=neurodegenerative%20disease" title=" neurodegenerative disease"> neurodegenerative disease</a>, <a href="https://publications.waset.org/abstracts/search?q=Alzheimer%E2%80%99s%20disease" title=" Alzheimer’s disease"> Alzheimer’s disease</a> </p> <a href="https://publications.waset.org/abstracts/18276/identification-of-potential-small-molecule-regulators-of-perk-kinase" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/18276.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">482</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> Wear Resistance and Thermal Stability of Tungsten Boride Layers Deposited by Magnetron Sputtering</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Justyna%20Chrzanowska">Justyna Chrzanowska</a>, <a href="https://publications.waset.org/abstracts/search?q=Jacek%20Hoffman"> Jacek Hoffman</a>, <a href="https://publications.waset.org/abstracts/search?q=Dariusz%20Garbiec"> Dariusz Garbiec</a>, <a href="https://publications.waset.org/abstracts/search?q=%C5%81ukasz%20Kurpaska"> Łukasz Kurpaska</a>, <a href="https://publications.waset.org/abstracts/search?q=Piotr%20Denis"> Piotr Denis</a>, <a href="https://publications.waset.org/abstracts/search?q=Tomasz%20Moscicki"> Tomasz Moscicki</a>, <a href="https://publications.waset.org/abstracts/search?q=Zygmunt%20Szymanski"> Zygmunt Szymanski</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Tungsten and boron compounds belong to the group of superhard materials and its hardness could exceed 40 GPa. In this study, the properties of the tungsten boride (WB) layers deposited in magnetron sputtering process are investigated. The sputtering process occurred from specially prepared targets that were composed of boron and tungsten mixed in molar ratio of 2.5 or 4.5 and sintered in spark plasma sintering process. WB layers were deposited on silicon (100) and stainless steel 304 substrates at room temperature (RT) or in 570 °C. Layers deposited in RT and in elevated temperature varied considerably. Layers deposited in RT are amorphous and have low adhesion. In contrast, the layers deposited in 570 °C are crystalline and have good adhesion. All deposited layers have a hardness about 40 GPa. Moreover, the friction coefficient of crystalline layers is 0.22 and wear rate is about 0.67•10-6 mm3N-1m-1. After material characterization the WB layers were annealed in argon atmosphere in 1000 °C for 1 hour. On the basis of X-Ray Diffraction analysis, it has been noted that the crystalline layers are thermally stable and do not change their phase composition, whereas the amorphous layers change their phase composition. Moreover, after annealing, on the surface of WB layers some cracks were observed. It is probably connected with the differences of the thermal expansion between the layer and the substrate. Despite of the presence of cracks, the wear resistance of annealed layers is still higher than the wear resistance of uncoated substrate. The analysis of the structure and properties of tungsten boride layers lead to the discussion about the application area of this material. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hard%20coatings" title="hard coatings">hard coatings</a>, <a href="https://publications.waset.org/abstracts/search?q=hard%20materials" title=" hard materials"> hard materials</a>, <a href="https://publications.waset.org/abstracts/search?q=magnetron%20sputtering" title=" magnetron sputtering"> magnetron sputtering</a>, <a href="https://publications.waset.org/abstracts/search?q=mechanical%20properties" title=" mechanical properties"> mechanical properties</a>, <a href="https://publications.waset.org/abstracts/search?q=tungsten%20boride" title=" tungsten boride"> tungsten boride</a> </p> <a href="https://publications.waset.org/abstracts/63347/wear-resistance-and-thermal-stability-of-tungsten-boride-layers-deposited-by-magnetron-sputtering" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/63347.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">288</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> Harvard Lawyers Perception of Intellectual Property and Digital Rights</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Dariusz%20Jemielniak">Dariusz Jemielniak</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The near future will bring significant changes to contemporary organizations and management, because of the rapidly increasing role of immaterial goods and knowledge workers. The area of copyright, IP, as well as digital (non-material) goods and media redistribution seems to be one of the major challenges for the economy and society in general, and management and organization studies in particular. The proposed paper shows the views and perceptions of fairness of digital media sharing among Harvard Law School LL.M. students, basing on 50 qualitative interviews and 100 questionnaires. The researcher took an ethnographic approach to the study and joined the 2016 Harvard LL.M. Facebook group, which allowed natural socializing and joining for in-person events and private parties more easily. After making acquaintance with many of the students, the researcher conducted a quantitative questionnaire with 100 respondents, allowing to better understand the respondents perception of fairness in digital files sharing in different contexts (depending on the price of the media, its availability, regional licensing, status of the copyright holder, etc.). Basing on the results of the questionnaire, the researcher followed up with long-term, open ended, loosely structured ethnographic interviews (50 interviews were conducted) to further deepen the understanding of the results. The major finding of the study is that Harvard lawyers, in spite of the highest possible understanding of law, as well as professional standards, generally approve of digital piracy in certain contexts. Interestingly, they are also more likely to approve of it if they work for the government rather than the private sector. The conclusions from this study allow a better understanding of how ‘fairness’ is perceived by the younger generation of law professionals, and also open grounds for a more rational licensing policing. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=piracy" title="piracy">piracy</a>, <a href="https://publications.waset.org/abstracts/search?q=digital%20sharing" title=" digital sharing"> digital sharing</a>, <a href="https://publications.waset.org/abstracts/search?q=perception%20of%20fairness" title=" perception of fairness"> perception of fairness</a>, <a href="https://publications.waset.org/abstracts/search?q=legal%20profession" title=" legal profession"> legal profession</a> </p> <a href="https://publications.waset.org/abstracts/72702/harvard-lawyers-perception-of-intellectual-property-and-digital-rights" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/72702.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">219</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> Anatomy of the Human Mitral Valve Leaflets: Implications for Transcatheter and Surgical Mitral Valve Repair Techniques</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Agata%20Krawczyk-Ozog">Agata Krawczyk-Ozog</a>, <a href="https://publications.waset.org/abstracts/search?q=Mateusz%20K.%20Holda"> Mateusz K.

The aim of this study was to characterize morphological variability of the mitral valve leaflets and to provide the size of their particular parts. Materials and Methods: In the study, we included 200 autopsied human hearts from Caucasian individuals (25% females) with mean age 47.5 (±17.9) without any valvular diseases. The morphology of the mitral valve was evaluated. The intercommissural and aorto-mural diameters of the mitral annulus were measured. All leaflets and their scallops were identified. The base and the height of the posteromedial commissure (PM-C), anterolateral commissure (AL-C), anterior leaflet (AL) and posterior leaflet (PL) with their scallops were measured. Results: The intercommissural diameter was 28.0±4.8 mm, the aorto-mural diameter 19.7±4.8 mm, circumference of the mitral annulus 89.9±12.6 mm and the area of the mitral valve 485.4±171.4 mm2. Classical mitral valves (AL+AL-C+PL(P1,P2,P3)+PM-C) were found in 141 (70.5%) specimens. In classical type, the mean AL base and height were 30.8±4.9 mm and 20.6±4.2 mm, while mean PL base and height 45.1±8.2 mm 12.9±2.8 mm respectively. The mean ratio of the AL base to PL base was 0.7±0.2. Variations in PL were found in 55 (27.5%) and in AL in 5 (2.5%) hearts. The most common variations were: valve with one accessory scallop (AcS) between P3 and PM-C (7%); AcS between P1 and AL-C (4%); connections of P2 and P3 scallops (4%); connections of P1 and P2 scallops (3%); AcS in AL (2.5%). All AcS were smaller than the main PL scallops. The mean intertrigonal distance was 21.9±3.8 mm. Conclusions: In all cases, the mitral valve is built by two main leaflets with possible variants in secondary to leaflets scallops (29.5%). The variations are largely associated with PL and are mostly related to the presence of AcS. Anatomically the AL is not divided into scallops, and it occupies 34.5% of the mitral annulus circumference. Understanding the anatomy of the mitral valve leaflets helps to planning and performing mitral valve repair procedures. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=accessory%20scallop" title="accessory scallop">accessory scallop</a>, <a href="https://publications.waset.org/abstracts/search?q=commissure" title=" commissure"> commissure</a>, <a href="https://publications.waset.org/abstracts/search?q=connected%20%20scallops" title=" connected scallops"> connected scallops</a>, <a href="https://publications.waset.org/abstracts/search?q=human%20heart" title=" human heart"> human heart</a>, <a href="https://publications.waset.org/abstracts/search?q=mitral%20leaflets" title=" mitral leaflets"> mitral leaflets</a>, <a href="https://publications.waset.org/abstracts/search?q=mitral%20valve" title=" mitral valve"> mitral valve</a> </p> <a href="https://publications.waset.org/abstracts/65755/anatomy-of-the-human-mitral-valve-leaflets-implications-for-transcatheter-and-surgical-mitral-valve-repair-techniques" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/65755.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">389</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">10</span> Biomechanical Assessment of Esophageal Elongation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Marta%20Kozu%C5%84">Marta Kozuń</a>, <a href="https://publications.waset.org/abstracts/search?q=Krystian%20Toczewski"> Krystian Toczewski</a>, <a href="https://publications.waset.org/abstracts/search?q=Sylwester%20Gerus"> Sylwester Gerus</a>, <a href="https://publications.waset.org/abstracts/search?q=Justyna%20Wolicka"> Justyna Wolicka</a>, <a href="https://publications.waset.org/abstracts/search?q=Kamila%20Boberek"> Kamila Boberek</a>, <a href="https://publications.waset.org/abstracts/search?q=Jaros%C5%82aw%20Filipiak"> Jarosław Filipiak</a>, <a href="https://publications.waset.org/abstracts/search?q=Dariusz%20Patkowski"> Dariusz Patkowski</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Long gap esophageal atresia is a congenital defect and is a challenge for pediatric surgeons all over the world. There are different surgical techniques in use to treat atresia. One of them is esophageal elongation but the optimal suture placement technique to achieve maximum elongation with low-risk complications is still unknown. The aim of the study was to characterize the process of esophageal elongation from the biomechanical point of view. Esophagi of white Pekin Duck was used as a model based on the size of this animal which is similar to a newborn (2.5-4kg). The specimens were divided into two groups: the control group (CG) and the group with sutures (SG). The esophagi of the control group were mounted in the grips of the MTS Tytron 250 testing machine and tensile test until rupture was performed. The loading speed during the test was 10mm/min. Then the SG group was tested. Each esophagus was cut into two equal parts and that were fused together using surgical sutures. The distance between both esophagus parts was 20mm. Ten both ends were mounted on the same testing machine and the tensile test with the same parameters was conducted. For all specimens, force and elongation were recorded. The biomechanical properties, i.e., the maximal force and maximal elongation, were determined on the basis of force-elongation curves. The maximal elongation was determined at the point of maximal force. The force achieved with the suture group was 10.1N±1.9N and 50.3N±11.6N for the control group. The highest elongation was also obtained for the control group: 18mm±3mm vs. 13.5mm ±2.4mm for the suture group. The presented study expands the knowledge of elongation of esophagi. It is worth emphasizing that the duck esophagus differs from the esophagus of a newborn, i.e., its wall lacks striated muscle cells. This is why the parts of animal esophagi used in the research are may characterized by different biomechanical properties in comparison with newborn tissue. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=long%20gap%20atresia%20treatment" title="long gap atresia treatment">long gap atresia treatment</a>, <a href="https://publications.waset.org/abstracts/search?q=esophageal%20elongation" title=" esophageal elongation"> esophageal elongation</a>, <a href="https://publications.waset.org/abstracts/search?q=biomechanical%20properties" title=" biomechanical properties"> biomechanical properties</a>, <a href="https://publications.waset.org/abstracts/search?q=soft%20tissue" title=" soft tissue"> soft tissue</a> </p> <a href="https://publications.waset.org/abstracts/148119/biomechanical-assessment-of-esophageal-elongation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/148119.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">100</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> Effect of cold water immersion on bone mineral metabolism in aging rats</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Irena%20Baranowska-Bosiacka">Irena Baranowska-Bosiacka</a>, <a href="https://publications.waset.org/abstracts/search?q=Mateusz%20Bosiacki"> Mateusz Bosiacki</a>, <a href="https://publications.waset.org/abstracts/search?q=Patrycja%20Kupnicka"> Patrycja Kupnicka</a>, <a href="https://publications.waset.org/abstracts/search?q=Anna%20Lubkowska"> Anna Lubkowska</a>, <a href="https://publications.waset.org/abstracts/search?q=Dariusz%20Chlubek"> Dariusz Chlubek</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Physical activity and a balanced diet are among the key factors of "healthy ageing". Physical effort, including swimming in cold water (including bathing in natural water reservoirs), is widely recognized as a hardening factor, with a positive effect on the mental and physical health. At the same time, there is little scientific evidence to verify this hypothesis. In the literature to date, it is possible to obtain data on the impact of these factors on selected physiological and biochemical parameters of the blood, at the same time there are no results of research on the effect of immersing in cold water on mineral metabolism, especially bones, hence it seems important to perform such an analysis in relation to the key elements such as calcium (Ca), magnesium (Mg) and phosphorus (P). Taking the above into account, a hypothesis was put forward about the possibility of a positive effect of exercise in cold water on mineral metabolism and bone density in aging rats. The aim of the study was to evaluate the effect of an 8-week swimming training on mineral metabolism and bone density in aging rats in response to exercise in cold water (5oC) in comparison to swimming in thermal comfort (36oC) and sedentary (control) rats of both sexes. The examination of the concentration of the examined elements in the bones was carried out using inductively coupled plasma atomic emission spectrometry (ICP-OES). The mineral density of the femurs of the rats was measured using the Hologic Horizon DEXA System® densitometer. The results of our study showed that swimming in cold water affects bone mineral metabolism in aging rats by changing the Ca, Mg, P concentration and at the same time increasing their bone density. In males, a decrease in Mg concentration and no changes in bone density were observed. In the light of the research results, it seems that swimming in cold water may be a factor that positively modifies the bone aging process by improving the mechanisms affecting their density. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=swimming%20in%20cold%20water" title="swimming in cold water">swimming in cold water</a>, <a href="https://publications.waset.org/abstracts/search?q=adaptation%20to%20cold%20water" title=" adaptation to cold water"> adaptation to cold water</a>, <a href="https://publications.waset.org/abstracts/search?q=bone%20mineral%20metabolism" title=" bone mineral metabolism"> bone mineral metabolism</a>, <a href="https://publications.waset.org/abstracts/search?q=aging" title=" aging"> aging</a> </p> <a href="https://publications.waset.org/abstracts/163011/effect-of-cold-water-immersion-on-bone-mineral-metabolism-in-aging-rats" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/163011.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">60</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> Artificial Intelligence Protecting Birds against Collisions with Wind Turbines</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Aleksandra%20Szurlej-Kielanska">Aleksandra Szurlej-Kielanska</a>, <a href="https://publications.waset.org/abstracts/search?q=Lucyna%20Pilacka"> Lucyna Pilacka</a>, <a href="https://publications.waset.org/abstracts/search?q=Dariusz%20G%C3%B3recki"> Dariusz Górecki</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The dynamic development of wind energy requires the simultaneous implementation of effective systems minimizing the risk of collisions between birds and wind turbines.

Since 2020, we have continued the survey on the validation of the subsequent version of the BPS detection and reaction system. Bird protection system (BPS) is a fully automatic camera system which allows one to estimate the distance of the bird to the turbine, classify its size and autonomously undertake various actions depending on the bird's distance and flight path. The BPS was installed and tested in a real environment at a wind turbine in northern Poland and Central Spain. The performed validation showed that at a distance of up to 300 m, the BPS performs at least as well as a skilled ornithologist, and large bird species are successfully detected from over 600 m. In addition, data collected by BPS systems installed in Spain showed that 60% of the detections of all birds of prey were from individuals approaching the turbine, and these detections meet the turbine shutdown criteria. Less than 40% of the detections of birds of prey took place at wind speeds below 2 m/s while the turbines were not working. As shown by the analysis of the data collected by the system over 12 months, the system classified the improved size of birds with a wingspan of more than 1.1 m in 90% and the size of birds with a wingspan of 0.7 - 1 m in 80% of cases. The collected data also allow the conclusion that some species keep a certain distance from the turbines at a wind speed of over 8 m/s (Aquila sp., Buteo sp., Gyps sp.), but Gyps sp. and Milvus sp. remained active at this wind speed on the tested area. The data collected so far indicate that BPS is effective in detecting and stopping wind turbines in response to the presence of birds of prey with a wingspan of more than 1 m. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=protecting%20birds" title="protecting birds">protecting birds</a>, <a href="https://publications.waset.org/abstracts/search?q=birds%20monitoring" title=" birds monitoring"> birds monitoring</a>, <a href="https://publications.waset.org/abstracts/search?q=wind%20farms" title=" wind farms"> wind farms</a>, <a href="https://publications.waset.org/abstracts/search?q=green%20energy" title=" green energy"> green energy</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainable%20development" title=" sustainable development"> sustainable development</a> </p> <a href="https://publications.waset.org/abstracts/162657/artificial-intelligence-protecting-birds-against-collisions-with-wind-turbines" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/162657.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">76</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> Preliminary Report on the Assessment of the Impact of the Kinesiology Taping Application versus Placebo Taping on the Knee Joint Position Sense</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Anna%20Hadamus">Anna Hadamus</a>, <a href="https://publications.waset.org/abstracts/search?q=Patryk%20Wasowski"> Patryk Wasowski</a>, <a href="https://publications.waset.org/abstracts/search?q=Anna%20Mosiolek"> Anna Mosiolek</a>, <a href="https://publications.waset.org/abstracts/search?q=Zbigniew%20Wronski"> Zbigniew Wronski</a>, <a href="https://publications.waset.org/abstracts/search?q=Sebastian%20Wojtowicz"> Sebastian Wojtowicz</a>, <a href="https://publications.waset.org/abstracts/search?q=Dariusz%20Bialoszewski"> Dariusz Bialoszewski</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: Kinesiology Taping is a very popular physiotherapy method, often used for healthy people, especially athletes, in order to stimulate the muscles and improve their performance. The aim of this study was to determine the effect of the muscle application of Kinesiology Taping on the joint position sense in active motion. Material and Methods: The study involved 50 healthy people - 30 men and 20 women, mean age was 23.2 years (range 18-30 years). The exclusion criteria were injuries and operations of the knee, which could affect the test results. The participants were divided randomly into two equal groups. The first group consisted of individuals with the applied Kinesiology Taping muscle application (KT group), whereas in the rest of the individuals placebo application from red adhesive tape was used (placebo group). Both applications were to enhance the effects of quadriceps muscle activity. Joint position sense (JPS) was evaluated in this study. Error of Active Reproduction of the Joint Position (EARJP) of the knee was measured in 45° flexion. The test was performed prior to applying the patch, with the applied application, then 24 hours after wearing, and after removing the tape. The interval between trials was not less than 30 minutes. Statistical analysis was performed using Statistica 12.0. We calculated distribution characteristics, Wilcoxon test, Friedman‘s ANOVA and Mann-Whitney U test. Results. In the KT group and the placebo group average test score of JPS before applying application KT were 3.48° and 5.16° respectively, after its application it was 4.84° and 4.88°, then after 24 hours of experiment JPS was 5.12° and 4.96°, and after application removal we measured 3.84° and 5.12° respectively. Differences over time in any of the groups were not statistically significant. There were also no significant differences between the groups. Conclusions: 1. Applying Kinesiology Taping to quadriceps muscle had no significant effect on the knee joint proprioception. Its use in order to improve sensorimitor skills seems therefore to be unreasonable. 2. No differences between applications of KT and placebo indicates that the clinical effect of stretch tape is minimal or absent. 3. The results are the basis for the continuation of prospective, randomized trials of numerous study groups. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=joint%20position%20sense" title="joint position sense">joint position sense</a>, <a href="https://publications.waset.org/abstracts/search?q=kinesiology%20taping" title=" kinesiology taping"> kinesiology taping</a>, <a href="https://publications.waset.org/abstracts/search?q=kinesiotaping" title=" kinesiotaping"> kinesiotaping</a>, <a href="https://publications.waset.org/abstracts/search?q=knee" title=" knee"> knee</a> </p> <a href="https://publications.waset.org/abstracts/65432/preliminary-report-on-the-assessment-of-the-impact-of-the-kinesiology-taping-application-versus-placebo-taping-on-the-knee-joint-position-sense" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/65432.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">339</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> Innovation Management in E-Health Care: The Implementation of New Technologies for Health Care in Europe and the USA</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Dariusz%20M.%20Trzmielak">Dariusz M.

The article focuses on demonstrating that technologies or products typically enable new functionality, a higher standard of service, or a higher level of knowledge and competence for clinicians. It also highlights the key benefits that can be achieved through the use of artificial intelligence, such as relieving clinicians of many tasks and enabling the expansion and greater specialisation of healthcare services. The comparative analysis allowed the authors to create a classification of new technologies in e-health according to health needs and benefits for patients, doctors, and healthcare systems, i.e., the main stakeholders in the implementation of new technologies and products in healthcare. The added value of the development of new technologies in healthcare is diagnosed. The work is both theoretical and practical in nature. The primary research methods are bibliographic analysis and analysis of research data and market potential of new solutions for healthcare organisations. The bibliographic analysis is complemented by the author's case studies of implemented technologies, mostly based on artificial intelligence or telemedicine. In the past, patients were often passive recipients, the end point of the service delivery system, rather than stakeholders in the system. One of the dangers of powerful new technologies is that patients may become even more marginalised. Healthcare will be provided and delivered in an increasingly administrative, programmed way. The doctor may also become a robot, carrying out programmed activities - using 'non-human services'. An alternative approach is to put the patient at the centre, using technologies, products, and services that allow them to design and control technologies based on their own needs. An important contribution to the discussion is to open up the different dimensions of the user (carer and patient) and to make them aware of healthcare units implementing new technologies. The authors of this article outline the importance of three types of patients in the successful implementation of new medical solutions. The impact of implemented technologies is analysed based on: 1) "Informed users", who are able to use the technology based on a better understanding of it; 2) "Engaged users" who play an active role in the broader healthcare system as a result of the technology; 3) "Innovative users" who bring their own ideas to the table based on a deeper understanding of healthcare issues. The authors' research hypothesis is that the distinction between informed, engaged, and innovative users has an impact on the perceived and actual quality of healthcare services. The analysis is based on case studies of new solutions implemented in different medical centres. In addition, based on the observations of the Polish author, who is a manager at the largest medical research institute in Poland, with analytical input from American and Norwegian partners, the added value of the implementations for patients, clinicians, and the healthcare system will be demonstrated. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=innovation" title="innovation">innovation</a>, <a href="https://publications.waset.org/abstracts/search?q=management" title=" management"> management</a>, <a href="https://publications.waset.org/abstracts/search?q=medicine" title=" medicine"> medicine</a>, <a href="https://publications.waset.org/abstracts/search?q=e-health" title=" e-health"> e-health</a>, <a href="https://publications.waset.org/abstracts/search?q=artificial%20intelligence" title=" artificial intelligence"> artificial intelligence</a> </p> <a href="https://publications.waset.org/abstracts/185984/innovation-management-in-e-health-care-the-implementation-of-new-technologies-for-health-care-in-europe-and-the-usa" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/185984.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">20</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> Destruction of Colon Cells by Nanocontainers of Ferromagnetic</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lukasz%20Szymanski">Lukasz Szymanski</a>, <a href="https://publications.waset.org/abstracts/search?q=Zbigniew%20Kolacinski"> Zbigniew Kolacinski</a>, <a href="https://publications.waset.org/abstracts/search?q=Grzegorz%20Raniszewski"> Grzegorz Raniszewski</a>, <a href="https://publications.waset.org/abstracts/search?q=Slawomir%20Wiak"> Slawomir Wiak</a>, <a href="https://publications.waset.org/abstracts/search?q=Lukasz%20Pietrzak"> Lukasz Pietrzak</a>, <a href="https://publications.waset.org/abstracts/search?q=Dariusz%20Koza"> Dariusz Koza</a>, <a href="https://publications.waset.org/abstracts/search?q=Karolina%20Przybylowska-Sygut"> Karolina Przybylowska-Sygut</a>, <a href="https://publications.waset.org/abstracts/search?q=Ireneusz%20Majsterek"> Ireneusz Majsterek</a>, <a href="https://publications.waset.org/abstracts/search?q=Zbigniew%20Kaminski"> Zbigniew Kaminski</a>, <a href="https://publications.waset.org/abstracts/search?q=Justyna%20Fraczyk"> Justyna Fraczyk</a>, <a href="https://publications.waset.org/abstracts/search?q=Malgorzata%20Walczak"> Malgorzata Walczak</a>, <a href="https://publications.waset.org/abstracts/search?q=Beata%20Kolasinska"> Beata Kolasinska</a>, <a href="https://publications.waset.org/abstracts/search?q=Adam%20Bednarek"> Adam Bednarek</a>, <a href="https://publications.waset.org/abstracts/search?q=Joanna%20Konka"> Joanna Konka</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The aim of this work is to investigate the influence of electromagnetic field from the range of radio frequencies on the desired nanoparticles for cancer therapy. In the article, the development and demonstration of the method and the model device for hyperthermic selective destruction of cancer cells are presented. This method was based on the synthesis and functionalization of carbon nanotubes serving as ferromagnetic material nanocontainers. The methodology of the production carbon - ferromagnetic nanocontainers (FNCs) includes: The synthesis of carbon nanotubes, chemical, and physical characterization, increasing the content of a ferromagnetic material and biochemical functionalization involving the attachment of the key addresses. The ferromagnetic nanocontainers were synthesised in CVD and microwave plasma system. Biochemical functionalization of ferromagnetic nanocontainers is necessary in order to increase the binding selectively with receptors presented on the surface of tumour cells. Multi-step modification procedure was finally used to attach folic acid on the surface of ferromagnetic nanocontainers. Pristine ferromagnetic carbon nanotubes are not suitable for application in medicine and biotechnology. Appropriate functionalization of ferromagnetic carbon nanotubes allows to receiving materials useful in medicine. Finally, a product contains folic acids on the surface of FNCs. The folic acid is a ligand of folate receptors – α which is overexpressed on the surface of epithelial tumours cells. It is expected that folic acids will be recognized and selectively bound by receptors presented on the surface of tumour cells. In our research, FNCs were covalently functionalized in a multi-step procedure. Ferromagnetic carbon nanotubes were oxidated using different oxidative agents. For this purpose, strong acids such as HNO3, or mixture HNO3 and H2SO4 were used. Reactive carbonyl and carboxyl groups were formed on the open sides and at the defects on the sidewalls of FNCs. These groups allow further modification of FNCs as a reaction of amidation, reaction of introduction appropriate linkers which separate solid surface of FNCs and ligand (folic acid). In our studies, amino acid and peptide have been applied as ligands. The last step of chemical modification was reaction-condensation with folic acid. In all reaction as coupling reagents were used derivatives of 1,3,5-triazine. The first trials in the device for hyperthermal RF generator have been done. The frequency of RF generator was in the ranges from 10 to 14Mhz and from 265 to 621kHz. Obtained functionalized nanoparticles enabled to reach the temperature of denaturation tumor cells in given frequencies. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cancer%20colon%20cells" title="cancer colon cells">cancer colon cells</a>, <a href="https://publications.waset.org/abstracts/search?q=carbon%20nanotubes" title=" carbon nanotubes"> carbon nanotubes</a>, <a href="https://publications.waset.org/abstracts/search?q=hyperthermia" title=" hyperthermia"> hyperthermia</a>, <a href="https://publications.waset.org/abstracts/search?q=ligands" title=" ligands"> ligands</a> </p> <a href="https://publications.waset.org/abstracts/52984/destruction-of-colon-cells-by-nanocontainers-of-ferromagnetic" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/52984.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">313</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">4</span> Assessment of Influence of Short-Lasting Whole-Body Vibration on Joint Position Sense and Body Balance–A Randomised Masked Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Anna%20Slupik">Anna Slupik</a>, <a href="https://publications.waset.org/abstracts/search?q=Anna%20Mosiolek"> Anna Mosiolek</a>, <a href="https://publications.waset.org/abstracts/search?q=Sebastian%20Wojtowicz"> Sebastian Wojtowicz</a>, <a href="https://publications.waset.org/abstracts/search?q=Dariusz%20Bialoszewski"> Dariusz Bialoszewski</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: Whole-body vibration (WBV) uses high frequency mechanical stimuli generated by a vibration plate and transmitted through bone, muscle and connective tissues to the whole body. Research has shown that long-term vibration-plate training improves neuromuscular facilitation, especially in afferent neural pathways, responsible for the conduction of vibration and proprioceptive stimuli, muscle function, balance and proprioception. Some researchers suggest that the vibration stimulus briefly inhibits the conduction of afferent signals from proprioceptors and can interfere with the maintenance of body balance. The aim of this study was to evaluate the influence of a single set of exercises associated with whole-body vibration on the joint position sense and body balance. Material and methods: The study enrolled 55 people aged 19-24 years. These individuals were randomly divided into a test group (30 persons) and a control group (25 persons). Both groups performed the same set of exercises on a vibration plate. The following vibration parameters: frequency of 20Hz and amplitude of 3mm, were used in the test group. The control group performed exercises on the vibration plate while it was off. All participants were instructed to perform six dynamic exercises lasting 30 seconds each with a 60-second period of rest between them. The exercises involved large muscle groups of the trunk, pelvis and lower limbs. Measurements were carried out before and immediately after exercise. Joint position sense (JPS) was measured in the knee joint for the starting position at 45° in an open kinematic chain. JPS error was measured using a digital inclinometer. Balance was assessed in a standing position with both feet on the ground with the eyes open and closed (each test lasting 30 sec). Balance was assessed using Matscan with FootMat 7.0 SAM software. The surface of the ellipse of confidence and front-back as well as right-left swing were measured to assess balance. Statistical analysis was performed using Statistica 10.0 PL software. Results: There were no significant differences between the groups, both before and after the exercise (p> 0.05). JPS did not change in both the test (10.7° vs. 8.4°) and control groups (9.0° vs. 8.4°). No significant differences were shown in any of the test parameters during balance tests with the eyes open or closed in both the test and control groups (p> 0.05). Conclusions. 1. Deterioration in proprioception or balance was not observed immediately after the vibration stimulus. This suggests that vibration-induced blockage of proprioceptive stimuli conduction can have only a short-lasting effect that occurs only as long as a vibration stimulus is present. 2. Short-term use of vibration in treatment does not impair proprioception and seems to be safe for patients with proprioceptive impairment. 3. These results need to be supplemented with an assessment of proprioception during the application of vibration stimuli. Additionally, the impact of vibration parameters used in the exercises should be evaluated. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=balance" title="balance">balance</a>, <a href="https://publications.waset.org/abstracts/search?q=joint%20position%20sense" title=" joint position sense"> joint position sense</a>, <a href="https://publications.waset.org/abstracts/search?q=proprioception" title=" proprioception"> proprioception</a>, <a href="https://publications.waset.org/abstracts/search?q=whole%20body%20vibration" title=" whole body vibration"> whole body vibration</a> </p> <a href="https://publications.waset.org/abstracts/32534/assessment-of-influence-of-short-lasting-whole-body-vibration-on-joint-position-sense-and-body-balance-a-randomised-masked-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/32534.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">328</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">3</span> Energy Metabolism and Mitochondrial Biogenesis in Muscles of Rats Subjected to Cold Water Immersion</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bosiacki%20Mateusz">Bosiacki Mateusz</a>, <a href="https://publications.waset.org/abstracts/search?q=Anna%20Lubkowska"> Anna Lubkowska</a>, <a href="https://publications.waset.org/abstracts/search?q=Dariusz%20Chlubek"> Dariusz Chlubek</a>, <a href="https://publications.waset.org/abstracts/search?q=Irena%20Baranowska-Bosiacka"> Irena Baranowska-Bosiacka</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Exposure to cold temperatures can be considered a stressor that can lead to adaptive responses. The present study hypothesized the possibility of a positive effect of cold water exercise on mitochondrial biogenesis and muscle energy metabolism in aging rats. The purpose of this study was to evaluate the effects of cold water exercise on energy status, purine compounds, and mitochondrial biogenesis in the muscles of aging rats as indicators of the effects of cold water exercise and their usefulness in monitoring adaptive changes. The study was conducted on 64 aging rats of both sexes, 15 months old at the time of the experiment. The rats (male and female separately) were randomly assigned to the following study groups: control, sedentary animals; 5°C groups animals - training swimming in cold water at 5°C; 36°C groups - animals training swimming in water at thermal comfort temperature. The study was conducted with the approval of the Local Ethical Committee for Animal Experiments. The animals in the experiment were subjected to swimming training for 9 weeks. During the first week of the study, the duration of the first swimming training was 2 minutes (on the first day), increasing daily by 0.5 minutes up to 4 minutes on the fifth day of the first week. From the second to the eighth week, the swimming training was 4 minutes per day, five days a week. At the end of the study, forty-eight hours after the last swim training, the animals were dissected. In the skeletal muscle tissue of the thighs of the rats, we determined the concentrations of ATP, ADP, AMP, Ado (HPLC), PGC-1a protein expression (Western blot), PGC1A, Mfn1, Mfn2, Opa1, and Drp1 gene expression (qRT PCR). The study showed that swimming in water at a thermally comfortable temperature improved the energy metabolism of the aging rat muscles by increasing the metabolic rate (increase in ATP, ADP, TAN, AEC) and enhancing mitochondrial fusion (increase in mRNA expression of regulatory proteins Mfn1 and Mfn2). Cold water swimming improved muscle energy metabolism in aging rats by increasing the rate of muscle energy metabolism (increase in ATP, ADP, TAN, AEC concentrations) and enhancing mitochondrial biogenesis and dynamics (increase in the mRNA expression of proteins of fusion-regulating factors – Mfn1, Mfn2, and Opa1, and the factor regulating mitochondrial fission – Drp1). The concentration of high-energy compounds and the expression of proteins regulating mitochondrial dynamics in the muscle may be a useful indicator in monitoring adaptive changes occurring in aging muscles under the influence of exercise in cold water. It represents a short-term adaptation to changing environmental conditions and has a beneficial effect on maintaining the bioenergetic capacity of muscles in the long term. Conclusion: exercise in cold water can exert positive effects on energy metabolism, biogenesis and dynamics of mitochondria in aging rat muscles. Enhancement of mitochondrial dynamics under cold water exercise conditions can improve mitochondrial function and optimize the bioenergetic capacity of mitochondria in aging rat muscles. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cold%20water%20immersion" title="cold water immersion">cold water immersion</a>, <a href="https://publications.waset.org/abstracts/search?q=adaptive%20responses" title=" adaptive responses"> adaptive responses</a>, <a href="https://publications.waset.org/abstracts/search?q=muscle%20energy%20metabolism" title=" muscle energy metabolism"> muscle energy metabolism</a>, <a href="https://publications.waset.org/abstracts/search?q=aging" title=" aging"> aging</a> </p> <a href="https://publications.waset.org/abstracts/163000/energy-metabolism-and-mitochondrial-biogenesis-in-muscles-of-rats-subjected-to-cold-water-immersion" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/163000.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">81</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> Response of Subfossile Diatoms, Cladocera, and Chironomidae in Sediments of Small Ponds to Changes in Wastewater Discharges from a Zn–Pb Mine</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ewa%20Szarek-Gwiazda">Ewa Szarek-Gwiazda</a>, <a href="https://publications.waset.org/abstracts/search?q=Agata%20Z.%20Wojtal"> Agata Z.

The response of organisms to environmental changes can be well recorded in sediments of the affected water bodies and may be reconstructed based on analyses of organisms' remains. The present study aimed at the response of diatoms (Bacillariophyta), Cladocera, and Chironomidae communities to the impact of Zn-Pb mine water discharge recorded in sediment cores of small subsidence ponds on the Chechło River floodplain (Silesia–Krakow Region, southern Poland). We hypothesize various responses of the above groups to high metal concentrations (Cd, Pb, Zn, and Cu). The investigated ponds were formed either during the peak of the ore exploitation (DOWN) or after mining cessation (UP). Currently, the concentrations of dissolved metals (in µg g⁻¹) in water reached up to 0.53 for Cd, 7.3 for Pb, and up to 47.1 for Zn. All the sediment cores from subsidence ponds were heavily polluted with Cd 6.7–612 μg g⁻¹, Pb 0.1–10.2 mg g⁻¹, and Zn 0.5–23.1 mg g⁻¹. Core sediments varied also in respect to pH 5.8-7.1 and concentrations of organic matter (5.7-39.8%). The impact of high metal concentrations was expressed by the occurrence of metal-tolerant taxa like diatoms – Nitzschia amphibia, Sellaphora nigri, and Surirella brebisonii var. kuetzingii; Cladocera – Chydorus sphaericus (dominated in cores from all ponds), and Chironomidae – Chironomus and Cricotopus especially in the DOWN ponds. Statistical analysis exhibited a negative impact of metals on some taxa of diatoms and Cladocera but only on Polypedilum sp. from Chironomidae. The abundance of such diatoms like Gomphonema utae, Staurosirella pinnata, Eunotia bilunaris, and Cladocera like Alona, Chydorus, Graptoleberis, and Pleuroxus decreased with increasing Pb concentration. However, the occurrence or dominance of more sensitive species of diatoms and Cladocera indicates their adaptation to higher metal loads, which was facilitated by neutral pH and slightly alkaline waters. Diatom assemblages were generally resistant to Zn, Pb, Cu, and Cd pollution, as indicated by their large similarity to populations from non-contaminated waters. Comparison with reference objects clearly indicates the dominance of Achnanthidium minutissimum, Staurosira venter, and Fragilaria gracilis in very diverse assemblages of unpolluted waters. The distribution of the Cladocera and Chironomidae taxa depended on the habitat type. The DOWN ponds with stagnant water and overgrown with macrophytes were more suitable for cladocerans (14 taxa, higher diversity) than the UP ponds with river water flowing through their centre and with a small share of macrophytes (8 taxa). The Chironominae, mainly Chironomus and Microspectra, were abundant in cores from the UP ponds with muddy bottoms. Inversely, the density of Orthocladiinae, especially genus Cricotopus, was related to the organic matter content and dominated in cores from the DOWN ponds. The presence of diatoms like Nitzschia amphibia, Sellaphora nigri, and Surirella brebisonii var. kuetzingii, cladocerans: Bosmina longirostris, Chydorus sphaericus, Alona affinis, and A. rectangularis as well as Chironomidae Chironomus sp. (UP ponds) and Psecrotanypus varius (DOWN ponds) indicate the influence of the water trophy on their distribution. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chironomidae" title="Chironomidae">Chironomidae</a>, <a href="https://publications.waset.org/abstracts/search?q=Cladocera" title=" Cladocera"> Cladocera</a>, <a href="https://publications.waset.org/abstracts/search?q=diatoms" title=" diatoms"> diatoms</a>, <a href="https://publications.waset.org/abstracts/search?q=metals" title=" metals"> metals</a>, <a href="https://publications.waset.org/abstracts/search?q=Zn-Pb%20mine" title=" Zn-Pb mine"> Zn-Pb mine</a>, <a href="https://publications.waset.org/abstracts/search?q=sediment%20cores" title=" sediment cores"> sediment cores</a>, <a href="https://publications.waset.org/abstracts/search?q=subsidence%20ponds" title=" subsidence ponds"> subsidence ponds</a> </p> <a href="https://publications.waset.org/abstracts/176661/response-of-subfossile-diatoms-cladocera-and-chironomidae-in-sediments-of-small-ponds-to-changes-in-wastewater-discharges-from-a-zn-pb-mine" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/176661.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">77</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> Low- and High-Temperature Methods of CNTs Synthesis for Medicine</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Grzegorz%20Raniszewski">Grzegorz Raniszewski</a>, <a href="https://publications.waset.org/abstracts/search?q=Zbigniew%20Kolacinski"> Zbigniew Kolacinski</a>, <a href="https://publications.waset.org/abstracts/search?q=Lukasz%20Szymanski"> Lukasz Szymanski</a>, <a href="https://publications.waset.org/abstracts/search?q=Slawomir%20Wiak"> Slawomir Wiak</a>, <a href="https://publications.waset.org/abstracts/search?q=Lukasz%20Pietrzak"> Lukasz Pietrzak</a>, <a href="https://publications.waset.org/abstracts/search?q=Dariusz%20Koza"> Dariusz Koza</a> </p> <p class="card-text"><strong>Abstract:</strong></p> One of the most promising area for carbon nanotubes (CNTs) application is medicine. One of the most devastating diseases is cancer. Carbon nanotubes may be used as carriers of a slowly released drug. It is possible to use of electromagnetic waves to destroy cancer cells by the carbon nanotubes (CNTs). In our research we focused on thermal ablation by ferromagnetic carbon nanotubes (Fe-CNTs). In the cancer cell hyperthermia functionalized carbon nanotubes are exposed to radio frequency electromagnetic field. Properly functionalized Fe-CNTs join the cancer cells. Heat generated in nanoparticles connected to nanotubes warm up nanotubes and then the target tissue. When the temperature in tumor tissue exceeds 316 K the necrosis of cancer cells may be observed. Several techniques can be used for Fe-CNTs synthesis. In our work, we use high-temperature methods where arc-discharge is applied. Low-temperature systems are microwave plasma with assisted chemical vapor deposition (MPCVD) and hybrid physical-chemical vapor deposition (HPCVD). In the arc discharge system, the plasma reactor works with a pressure of He up to 0,5 atm. The electric arc burns between two graphite rods. Vapors of carbon move from the anode, through a short arc column and forms CNTs which can be collected either from the reactor walls or cathode deposit. This method is suitable for the production of multi-wall and single-wall CNTs. A disadvantage of high-temperature methods is a low purification, short length, random size and multi-directional distribution. In MPCVD system plasma is generated in waveguide connected to the microwave generator. Then containing carbon and ferromagnetic elements plasma flux go to the quartz tube. The additional resistance heating can be applied to increase the reaction effectiveness and efficiency. CNTs nucleation occurs on the quartz tube walls. It is also possible to use substrates to improve carbon nanotubes growth. HPCVD system involves both chemical decomposition of carbon containing gases and vaporization of a solid or liquid source of catalyst. In this system, a tube furnace is applied. A mixture of working and carbon-containing gases go through the quartz tube placed inside the furnace. As a catalyst ferrocene vapors can be used. Fe-CNTs may be collected then either from the quartz tube walls or on the substrates. Low-temperature methods are characterized by higher purity product. Moreover, carbon nanotubes from tested CVD systems were partially filled with the iron. Regardless of the method of Fe-CNTs synthesis the final product always needs to be purified for applications in medicine. The simplest method of purification is an oxidation of the amorphous carbon. Carbon nanotubes dedicated for cancer cell thermal ablation need to be additionally treated by acids for defects amplification on the CNTs surface what facilitates biofunctionalization. Application of ferromagnetic nanotubes for cancer treatment is a promising method of fighting with cancer for the next decade.
