adverse events after sevoflurane anesthesia in pediatric patients. The efficacy of prophylactic remifentanil, one of mu opioid agonist, in preventing EA is controversial. This meta-analysis assessed the effectiveness of remifentanil to decrease the incidence of EA from sevoflurane anesthesia in children. We searched for randomized controlled trials comparing sevoflurane alone anesthesia with sevoflurane and remifentanil anesthesia to prevent EA in the Cochrane Library, Embase, Pubmed, and KoreaMed, and included 6 studies with 361 patients. The number of patients of reporting EA was summarized using risk ratio (RR) with 95% confidence interval (CI), with point estimates and 95CIs derived from a random effects Mantel-Haenszel method. Overall incidence of EA was about 41%. Compared with sevoflurane alone anesthesia, intravenous infusion of remifentanil with sevoflurane significantly reduced the incidence of EA (RR 0.53, 95% CI 0.39-0.73, P < 0.0001), (heterogeneity, I2 = 0, P = 0.42). This meta-analysis suggested that continuous infusion of remifentanil could be effective in decreasing the EA of about 47% after sevoflurane anesthesia. However, considering limitations of the included studies, more randomized controlled studies are required to verify our results. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=emergence%20agitation" title="emergence agitation">emergence agitation</a>, <a href="https://publications.waset.org/abstracts/search?q=meta-analysis" title=" meta-analysis"> meta-analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=remifentanil" title=" remifentanil"> remifentanil</a>, <a href="https://publications.waset.org/abstracts/search?q=pediatrics" title=" pediatrics"> pediatrics</a> </p> <a href="https://publications.waset.org/abstracts/76607/the-effect-of-remifentanil-on-emergence-agitation-after-sevoflurane-anesthesia-in-children-a-meta-analysis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/76607.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">381</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">1012</span> Preoperative Parental Anxiety is not Associated with Postoperative Emergence Agitation in Children Undergoing Adenoidectomy and/or Tonsillectomy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=S.%20%C3%96cal">S.

Çertuğ</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Emergence agitation (EA) is defined as a dissociated state of consciousness during the early post-anesthesia period in which the child is inconsolable, irritable, uncompromising or uncooperative, typically thrashing, crying, moaning, or incoherent, and not recognizing or identifying familiar and known objects or people. Some studies found preoperative parental anxiety to be a predictor of EA. Methods: Seventy-four children, between the ages of 3-12 undergoing adenoidectomy/tonsillectomy at Ege University Hospital, were studied. Anesthesia was induced and maintained using 2% sevoflurane in 50% oxygen and 50% air following a premedicative dose of 0.5mg/kg oral midazolam. After the children were taken into the operating theater, the mothers were given the State-Trait Anxiety Inventory (STAI) questionnaire. To evaluate EA, Post Anesthetic Emergence Delirium (PAED) score of the children were noted every 10min during the first 30min of the postoperative period. EA was defined with a highest PAED score of ≥ 10, and non-EA with a highest PAED score of ≤ 9. Results: In this study, the incidence of postoperative EA was 31% (34% under the age of 6 and 19% over). Mothers of children with EA were found not to be significantly more anxious on STAI compared to mothers of non-EA children. Conclusions: Contrary to some earlier studies, we were unable to find an association between preoperative parental anxiety and postoperative EA. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=parental%20anxiety" title="parental anxiety">parental anxiety</a>, <a href="https://publications.waset.org/abstracts/search?q=emergence%20agittion" title=" emergence agittion"> emergence agittion</a>, <a href="https://publications.waset.org/abstracts/search?q=Post%20Anesthetic%20Emergence%20Delirium" title=" Post Anesthetic Emergence Delirium"> Post Anesthetic Emergence Delirium</a>, <a href="https://publications.waset.org/abstracts/search?q=anesthesia" title=" anesthesia"> anesthesia</a> </p> <a href="https://publications.waset.org/abstracts/29527/preoperative-parental-anxiety-is-not-associated-with-postoperative-emergence-agitation-in-children-undergoing-adenoidectomy-andor-tonsillectomy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/29527.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">349</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">1011</span> The Effect of Temperature, Contact Time and Agitation Speed During Pre-Treatment on Elution of Gold</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=T.%20P.%20Oladele">T.

It was shown that there are interactions between parameters during pre-treatment. At 80oC, recovery is independent of the contact time while the maximum recovery is obtained in the absence of agitation (0rpm). Increase in agitation speed from 0 rev/min to 1200 rev/min showed a decrease in recovery of approximately 20 percent at 80°C. Recovery with increased time from 15 minutes to 45 minutes is only pronounced at 25°C with approximately 4 percent increase at all agitation speeds. The results from elution recovery are aimed to give insight into the mechanisms of pre-treatment under the combinations of the chosen parameters. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=gold" title="gold">gold</a>, <a href="https://publications.waset.org/abstracts/search?q=temperature" title=" temperature"> temperature</a>, <a href="https://publications.waset.org/abstracts/search?q=contact%20time" title=" contact time"> contact time</a>, <a href="https://publications.waset.org/abstracts/search?q=agitation%20speed" title=" agitation speed"> agitation speed</a>, <a href="https://publications.waset.org/abstracts/search?q=recovery" title=" recovery"> recovery</a> </p> <a href="https://publications.waset.org/abstracts/20502/the-effect-of-temperature-contact-time-and-agitation-speed-during-pre-treatment-on-elution-of-gold" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/20502.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">501</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">1010</span> Experimental Investigation of Heat Transfer and Scale Growth Characteristics of Crystallisation Scale in Agitation Tank</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Prasanjit%20%20Das">Prasanjit Das</a>, <a href="https://publications.waset.org/abstracts/search?q=M%20.M.%20K.%20Khan"> M .M.

To investigate the crystallisation scale growth of normal solubility salt, a lab-scale agitation tank with and without baffles were used as a benchmark using potassium nitrate as the test fluid. Potassium nitrate (KNO3) solution in this test leads to crystallisation scale on heat transfer surfaces. This experimental investigation has focused on the effect of surface crystallisation of potassium nitrate on the low-temperature heat exchange surfaces on the wall of the agitation tank. The impeller agitation rate affects the scaling rate at the low-temperature agitation wall and it shows a decreasing scaling rate with an increasing agitation rate. It was observed that there was a significant variation of heat transfer coefficients and scaling resistance coefficients with different agitation rate as well as with varying impeller size, tank with and without baffles and solution concentration. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=crystallisation" title="crystallisation">crystallisation</a>, <a href="https://publications.waset.org/abstracts/search?q=heat%20transfer%20coefficient" title=" heat transfer coefficient"> heat transfer coefficient</a>, <a href="https://publications.waset.org/abstracts/search?q=scale" title=" scale"> scale</a>, <a href="https://publications.waset.org/abstracts/search?q=resistance" title=" resistance"> resistance</a> </p> <a href="https://publications.waset.org/abstracts/80971/experimental-investigation-of-heat-transfer-and-scale-growth-characteristics-of-crystallisation-scale-in-agitation-tank" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/80971.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">193</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">1009</span> Experimental Investigation of Fluid Dynamic Effects on Crystallisation Scale Growth and Suppression in Agitation Tank</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Prasanjit%20Das">Prasanjit Das</a>, <a href="https://publications.waset.org/abstracts/search?q=M.%20M.%20K.%20Khan"> M.

To better understand scale growth and suppression, an experimental model is proposed in this study for supersaturated crystallised solutions commonly found in mineral process plants. In this experiment, surface crystallisation of potassium nitrate (KNO3) on the wall of the agitation tank and agitation effects on the scale growth and suppression are studied. The new quantitative scale suppression model predicts that at lower agitation speed, the scale growth rate is enhanced and at higher agitation speed, the scale suppression rate increases due to the increased flow erosion effect. A lab-scale agitation tank with and without baffles were used as a benchmark in this study. The fluid dynamic effects on scale growth and suppression in the agitation tank with three different size impellers (diameter 86, 114, 160 mm and model A310 with flow number 0.56) at various ranges of rotational speed (up to 700 rpm) and solution with different concentration (4.5, 4.75 and 5.25 mol/dm3) were investigated. For more elucidation, the effects of the different size of the impeller on wall surface scale growth and suppression rate as well as bottom settled scale accumulation rate are also discussed. Emphasis was placed on applications in the mineral industry, although results are also relevant to other industrial applications. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=agitation%20tank" title="agitation tank">agitation tank</a>, <a href="https://publications.waset.org/abstracts/search?q=crystallisation" title=" crystallisation"> crystallisation</a>, <a href="https://publications.waset.org/abstracts/search?q=impeller%20speed" title=" impeller speed"> impeller speed</a>, <a href="https://publications.waset.org/abstracts/search?q=scale" title=" scale"> scale</a> </p> <a href="https://publications.waset.org/abstracts/80970/experimental-investigation-of-fluid-dynamic-effects-on-crystallisation-scale-growth-and-suppression-in-agitation-tank" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/80970.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">228</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">1008</span> Nickel Electroplating in Post Supercritical CO2 Mixed Watts Bath under Different Agitations </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chun-Ying%20Lee">Chun-Ying Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Kun-Hsien%20Lee"> Kun-Hsien Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Bor-Wei%20Wang"> Bor-Wei Wang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The process of post-supercritical CO<sub>2</sub> electroplating uses the electrolyte solution after being mixed with supercritical CO<sub>2</sub> and released to atmospheric pressure. It utilizes the microbubbles that form when oversaturated CO<sub>2</sub> in the electrolyte returns to gaseous state, which gives the similar effect of pulsed electroplating. Under atmospheric pressure, the CO<sub>2</sub> bubbles gradually diffuse. Therefore, the introduction of ultrasound and/or other agitation can potentially excite the CO<sub>2</sub> microbubbles to achieve an electroplated surface of even higher quality. In this study, during the electroplating process, three different modes of agitation: magnetic stirrer agitation, ultrasonic agitation and a combined mode (magnetic + ultrasonic) were applied, respectively, in order to obtain an optimal surface morphology and mechanical properties for the electroplated Ni coating. It is found that the combined agitation mode at a current density of 40 A/dm<sup>2</sup> achieved the smallest grain size, lower surface roughness, and produced an electroplated Ni layer that achieved hardness of 320 HV, much higher when compared with conventional method, which were usually in the range of 160 to 300 HV. However, at the same time, the electroplating with combined agitation developed a higher internal stress of 320 MPa due to the lower current efficiency of the process and finer grain in the coating. Moreover, a new control methodology for tailoring the coating’s mechanical property through its thickness was demonstrated by the timely introduction of ultrasonic agitation during the electroplating process with post supercritical CO<sub>2</sub> mixed electrolyte. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=nickel%20electroplating" title="nickel electroplating">nickel electroplating</a>, <a href="https://publications.waset.org/abstracts/search?q=micro-bubbles" title=" micro-bubbles"> micro-bubbles</a>, <a href="https://publications.waset.org/abstracts/search?q=supercritical%20carbon%20dioxide" title=" supercritical carbon dioxide"> supercritical carbon dioxide</a>, <a href="https://publications.waset.org/abstracts/search?q=ultrasonic%20agitation" title=" ultrasonic agitation"> ultrasonic agitation</a> </p> <a href="https://publications.waset.org/abstracts/66742/nickel-electroplating-in-post-supercritical-co2-mixed-watts-bath-under-different-agitations" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/66742.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">283</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">1007</span> Numerical Modeling of Storm Swells in Harbor by Boussinesq Equations Model</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mustapha%20Kamel%20Mihoubi">Mustapha Kamel Mihoubi</a>, <a href="https://publications.waset.org/abstracts/search?q=Hocine%20Dahmani"> Hocine Dahmani </a> </p> <p class="card-text"><strong>Abstract:</strong></p> The purpose of work is to study the phenomenon of agitation of storm waves at basin caused by different directions of waves relative to the current provision thrown numerical model based on the equation in shallow water using Boussinesq model MIKE 21 BW.

ED is a transient state (minutes to hours) of marked agitation after the discontinuation of general anesthesia, which does not respond to consoling measures. On the other hand, POD without identifiable etiology is not temporally related to emergence from anesthesia. These patients often emerge smoothly and may be lucid in the post-anesthesia care unit (PACU), but may develop fluctuating mental status, most commonly between postoperative days one and three. General anesthesia (GA) has been identified as a risk factor for POCD. Cranial surgeries involve brain handling in addition to exposure to GA. We hypothesize that the incidence of postoperative delirium after cranial surgery is twice that of spinal surgery. The primary objective of this study was to evaluate the incidence of emergence delirium and postoperative delirium in patients undergoing cranial and spinal neurosurgeries. The secondary objective was to identify the perioperative risk factors of ED and POD. Methods: This was a prospective cohort observation study conducted from March 2020 to September 2023 conducted at a tertiary neurocentre. After obtaining institutional ethics committee approval, adult patients undergoing cranial or spinal surgery with a Glasgow coma scale of 15 were included in the study. Patients undergoing cranial surgery are considered exposed to risk factors, while patients undergoing spinal surgery are considered unexposed. All study subjects received standard general anesthesia. About twenty perioperative parameters were identified as risk factors for POCD. ED was assessed using the Riker sedation agitation scale, and POD was assessed using the confusion assessment method. A sample size of 2000 patients was planned with 1000 each cranial and spinal cases. However, around 700 spinal patients could be recruited for this study. Results: In this study, about two thousand patients were screened for inclusion. However, 1185 cranial cases and 742 spinal cases were considered for final analysis. Both the groups were similar in terms of demographics. Incidence of ED was 25.8% after cranial surgery vs 10.24% after spinal surgery (relative risk 2.5). The incidence of POD after cranial surgery is 20.25% vs 2.15% after cranial surgery (relative risk 9.3). All the proposed risk factors were assessed using binomial logistic regression. Conclusion: Cranial cases expose patients to a nine times higher risk for the development of postoperative delirium. The presence of ED predisposes to POD representing a spectrum. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=post%20operative%20cognitive%20dysfunction" title="post operative cognitive dysfunction">post operative cognitive dysfunction</a>, <a href="https://publications.waset.org/abstracts/search?q=Neurosurgical%20patients%20cohort%20study" title=" Neurosurgical patients cohort study"> Neurosurgical patients cohort study</a>, <a href="https://publications.waset.org/abstracts/search?q=cohort%20study" title=" cohort study"> cohort study</a>, <a href="https://publications.waset.org/abstracts/search?q=emergence%20delirium" title=" emergence delirium"> emergence delirium</a> </p> <a href="https://publications.waset.org/abstracts/195788/incidence-of-and-risk-factors-for-post-operative-cognitive-dysfunction-pocd-in-neurosurgical-patients-a-prospective-cohort-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/195788.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">19</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">1003</span> Production and Characterization of Sol-Enhanced Zn-Ni-Al2O3 Nano Composite Coating</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Soroor%20Ghaziof">Soroor Ghaziof</a>, <a href="https://publications.waset.org/abstracts/search?q=Wei%20Gao"> Wei Gao</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Sol-enhanced Zn-Ni-Al2O3 nano-composite coatings were electroplated on mild steel by our newly developed sol-enhanced electroplating method.

The chemical composition, microstructure and mechanical properties of the composite and alloy coatings deposited at two different agitation speed were investigated. The structure of all coatings was single γ-Ni5Zn21 phase. The composite coatings possess refined crystals with higher microhardness compared to Zn-Ni alloy coatings. The wear resistance of Zn-Ni coatings was improved significantly by incorporation of alumina nano particles into the coatings. Higher agitation speed provided more uniform coatings with smaller grain sized and slightly higher microhardness. Considering composite coatings, high agitation speeds may facilitate co-deposition of alumina in the coatings. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=microhardness" title="microhardness">microhardness</a>, <a href="https://publications.waset.org/abstracts/search?q=sol-enhanced%20electroplating" title=" sol-enhanced electroplating"> sol-enhanced electroplating</a>, <a href="https://publications.waset.org/abstracts/search?q=wear%20resistance" title=" wear resistance"> wear resistance</a>, <a href="https://publications.waset.org/abstracts/search?q=Zn-Ni-Al2O3%20composite%20coatings" title=" Zn-Ni-Al2O3 composite coatings "> Zn-Ni-Al2O3 composite coatings </a> </p> <a href="https://publications.waset.org/abstracts/26084/production-and-characterization-of-sol-enhanced-zn-ni-al2o3-nano-composite-coating" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/26084.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">507</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">1002</span> Conditions Required for New Sector Emergence: Results from a Systematic Literature Review</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Laurie%20Prange-Martin">Laurie Prange-Martin</a>, <a href="https://publications.waset.org/abstracts/search?q=Romeo%20Turcan"> Romeo Turcan</a>, <a href="https://publications.waset.org/abstracts/search?q=Norman%20Fraser"> Norman Fraser</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The aim of this study is to identify the conditions required and describe the process of emergence for a new economic sector created from new or established businesses. A systematic literature review of English-language studies published from 1983 to 2016 was conducted using the following databases: ABI/INFORM Complete; Business Source Premiere; Google Scholar; Scopus; and Web of Science. The two main terms of business sector and emergence were used in the systematic literature search, along with another seventeen synonyms for each these main terms. From the search results, 65 publications met the requirements of an empirical study discussing and reporting the conditions of new sector emergence. A meta-analysis of the literature examined suggest that there are six favourable conditions and five key individuals or groups required for new sector emergence. In addition, the results from the meta-analysis showed that there are eighteen theories used in the literature to explain the phenomenon of new sector emergence, which can be grouped in three study disciplines. With such diversity in theoretical frameworks used in the 65 empirical studies, the authors of this paper propose the development of a new theory of sector emergence. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=economic%20geography" title="economic geography">economic geography</a>, <a href="https://publications.waset.org/abstracts/search?q=new%20sector%20emergence" title=" new sector emergence"> new sector emergence</a>, <a href="https://publications.waset.org/abstracts/search?q=economic%20diversification" title=" economic diversification"> economic diversification</a>, <a href="https://publications.waset.org/abstracts/search?q=regional%20economies" title=" regional economies"> regional economies</a> </p> <a href="https://publications.waset.org/abstracts/63203/conditions-required-for-new-sector-emergence-results-from-a-systematic-literature-review" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/63203.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">274</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">1001</span> Studies on the Emergence Pattern of Cercariae from Fresh Water Snails (Mollusca: Gastropoda)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=V.%20R.%20Kakulte">V.

Children with emergence delirium are often confused; they cry, are involuntarily physically active and are almost impossible to console. The prevalence varies considerably between about 13% and 53%. Research has mainly focused on how different medication accents affect the incidence of emergence delirium, but less is known about parents’ experiences of emergence delirium during the recovery process. Aim: The aim of this study was to describe parents’ experiences and reflections during their child's emergence delirium behaviour when recovering from anaesthesia. Method: The study has a qualitative design, and the data has been analyzed using thematic analysis. A total of 16 parents were interviewed at two county hospitals in Sweden. Results: When the parents reunited with their child at the recovering unit, they felt as if they were encountering an incomprehensible scenario. When watching their child demonstrating emergence delirium, they experienced fear and insecurity and had feelings of powerlessness and guilt. Information and previous experience turned out to offer relief and being seen by the healthcare staff when they, in their vulnerability, failed to reach or console their child gave hope and energy. Conclusion: Emergence delirium must be extensively considered in children undergoing general anaesthesia. Healthcare staff needs to be aware of the parental difficulties it may cause. There is also important to know what parents experience as relieving, such as receiving information and when staff members are being available, responsive and supportive during the wake-up period. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=emergence%20delirium" title="emergence delirium">emergence delirium</a>, <a href="https://publications.waset.org/abstracts/search?q=experiences" title=" experiences"> experiences</a>, <a href="https://publications.waset.org/abstracts/search?q=pediatrics" title=" pediatrics"> pediatrics</a>, <a href="https://publications.waset.org/abstracts/search?q=parents" title=" parents"> parents</a>, <a href="https://publications.waset.org/abstracts/search?q=postoperative%20care" title=" postoperative care"> postoperative care</a> </p> <a href="https://publications.waset.org/abstracts/149959/postoperative-emergence-delirium-in-children-an-incomprehensible-scenario-for-parents" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/149959.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">134</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">999</span> Biosorption of Lead (II) from Aqueous Solution Using Marine Algae Chlorella pyrenoidosa</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Pramod%20Kumar">Pramod Kumar</a>, <a href="https://publications.waset.org/abstracts/search?q=A.%20V.%20N.%20Swamy"> A.

Results are presented showing the sorption of Pb(II) from solutions by biomass of commonly available marine algae Chlorella sp. The ability of marine algae Chlorella pyrenoidosa to remove heavy metal ion (Pb(II)) from aqueous solutions has been studied in this work. The biosorption properties of the biosorbent like equilibrium agitation time, optimum pH, temperature and initial solute concentration were investigated on metal uptake by showing respective profiles. The maximum metal uptake was found to be 10.27 mg/g. To achieve this metal uptake, the optimum conditions were found to be 30 min as equilibrium agitation time, 4.6 as optimum pH, 60 ppm of initial solute concentration. Lead concentration is determined by atomic absorption spectrometer. The process was found to be well fitted for pseudo-second order kinetics. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biosorption" title="biosorption">biosorption</a>, <a href="https://publications.waset.org/abstracts/search?q=heavy%20metal%20ions" title=" heavy metal ions"> heavy metal ions</a>, <a href="https://publications.waset.org/abstracts/search?q=agitation%20time" title=" agitation time"> agitation time</a>, <a href="https://publications.waset.org/abstracts/search?q=metal%20uptake" title=" metal uptake"> metal uptake</a>, <a href="https://publications.waset.org/abstracts/search?q=aqueous%20solution" title=" aqueous solution"> aqueous solution</a> </p> <a href="https://publications.waset.org/abstracts/12684/biosorption-of-lead-ii-from-aqueous-solution-using-marine-algae-chlorella-pyrenoidosa" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/12684.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">376</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">998</span> Effect of Aeration on Bacterial Cellulose (BC) Production by Gluconacetobacter xylinus DSM46604 in Batch Fermentation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Azila%20Adnan">Azila Adnan</a>, <a href="https://publications.waset.org/abstracts/search?q=Giridhar%20R.%20Nair"> Giridhar R.

However, the quantitative growth of this algal type is still low as it tends to precipitates on the bottom. Beside, the lipid concentration is still low when grown in autotrophic condition. In contrast, heterotrophic condition can enhance the lipid concentration. The combination of autotrophic condition and agitation treatment was conducted to increase the density of the culture. On the other hand, a heterotrophic condition was set up to raise the lipid production. A two-stage experiment was applied to increase the density at the first step and to increase the lipid concentration in the next step. The autotrophic condition resulted higher density but lower lipid concentration compared to heterotrophic one. The agitation treatment produced higher density in both autotrophic and heterotrophic conditions. The two-stage experiment managed to enhance the density during the autotrophic stage and the lipid concentration during the heterotrophic stage. The highest yield was performed by using 0.4% v/v glycerol as a carbon source (2.9±0.016 x 106 cells w/w) attained 7 days after the heterotrophic stage began. The lipid concentration was stable starting from day 7. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=agitation" title="agitation">agitation</a>, <a href="https://publications.waset.org/abstracts/search?q=glycerol" title=" glycerol"> glycerol</a>, <a href="https://publications.waset.org/abstracts/search?q=heterotrophic" title=" heterotrophic"> heterotrophic</a>, <a href="https://publications.waset.org/abstracts/search?q=lipid%20productivity" title=" lipid productivity"> lipid productivity</a>, <a href="https://publications.waset.org/abstracts/search?q=Meyerella%20planktonica" title=" Meyerella planktonica"> Meyerella planktonica</a> </p> <a href="https://publications.waset.org/abstracts/29280/cell-biomass-and-lipid-productivities-of-meyerella-planktonica-under-autotrophic-and-heterotrophic-growth-conditions" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/29280.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">346</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">996</span> Assessment of Cassava Varieties in Ecuador for the Production of Lactic Acid From Starch by-Products</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Pedro%20Maldonado-Alvarado">Pedro Maldonado-Alvarado</a> </p> <p class="card-text"><strong>Abstract:</strong></p> An important cassava quality production was detected in Ecuador. However, in this country, few products with low adding-value are produced from the tuber and none from cassava by-products. To our best knowledge, lactic acid was produced from Ecuadorian cassava bagasse starch in a biotechnological way. The objective of this contribution was to study the influence of the fermentation variables (pH and agitation) on the lactic acid production of Ecuadorian cassava varieties from bagasse starch. Enzymatic hydrolysis of cassava bagasse starch for INIAP 650 and INIAP 651 varieties spread in Ecuador was performed using α-amylase and amyloglucosidase. Then, glucose was fermented by Lactobacillus leichmannii strains in different conditions of agitation (0 and 150 rpm) and pH (4.5, 5.0, and 5.5). Significant differences in ash, fibre, protein, lipids, and amylose were found in cassava bagasse starch of INIAP 650 and INIAP 651 with 1.4 and 1.3%, 4.3 and 6%, 1.2 and 2.1%, 1.9 and 1.5%, and 24.3 and 26.5%, respectively. The determination of lactic acid was performed by potentiometric and FTIR analysis. Conversions of cassava bagasse to reduced sugars were 71.7 and 85.1% for INIAP 650 and INIAP 651, respectively. The best lactic acid concentrations were 27.6 and 33.5 g/L, obtained at agitation 150 rpm and pH 5.5 for INIAP 650 and INIAP 651. Qualitative analysis conducted by FTIR spectrophotometry confirmed the presence of lactic acid in the reacted products. This investigation could contribute to the valorisation of residues from promising cassava varieties in Ecuador and hence to increase the development of this country. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bagasse%20starch" title="bagasse starch">bagasse starch</a>, <a href="https://publications.waset.org/abstracts/search?q=cassava" title=" cassava"> cassava</a>, <a href="https://publications.waset.org/abstracts/search?q=Ecuador" title=" Ecuador"> Ecuador</a>, <a href="https://publications.waset.org/abstracts/search?q=fermentation" title=" fermentation"> fermentation</a>, <a href="https://publications.waset.org/abstracts/search?q=lactic%20acid" title=" lactic acid"> lactic acid</a> </p> <a href="https://publications.waset.org/abstracts/136271/assessment-of-cassava-varieties-in-ecuador-for-the-production-of-lactic-acid-from-starch-by-products" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/136271.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">198</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">995</span> Mulberry Leave: An Efficient and Economical Adsorbent for Remediation of Arsenic (V) and Arsenic (III) Contaminated Water</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Saima%20Q.%20Memon">Saima Q.

Its role would be more apparent when the physician encounters a mass casualty in a war zone or even a military prehospital. Having sedative and analgesic properties, rapid onset and offset effects, and maintaining the cardiovascular and respiratory contain are the main reason for selecting Ketamine as a good choice in the war zone. Methods: In a prospective interventional study in a war zone, we have selected and followed two groups of casualties for pain management. All were men with an average age of 26.6±8 y/o and 27.5 ±7 y/o in A and B groups, respectively. Group A received only Ketamine and Group B received Ketamine and diazepam. Results: This study showed that all of the injured patients who received Ketamine had experienced some agitation, and they may finally need benzodiazepines for sedation, but in group B that received benzodiazepine before or simultaneous with Ketamine, the agitation was significantly reduced. (P Value ≤0.05) Conclusion: Various factors may affect pain score and perception; patients' culture, mental health, previous drug usage, and addiction could alter the pain score in similar situations. It seems that the significant agitation is due to catecholamine release in stressful Moments of the battlefield. Accordingly, this situation could be exacerbated due to ketamine properties. Nonetheless, as a good choice in the war zone, Ketamine is now recommended to combine with benzodiazepines for procedural sedation and analgesia (PSA). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=battlefield" title="battlefield">battlefield</a>, <a href="https://publications.waset.org/abstracts/search?q=ketamine" title=" ketamine"> ketamine</a>, <a href="https://publications.waset.org/abstracts/search?q=benzodiazepine" title=" benzodiazepine"> benzodiazepine</a>, <a href="https://publications.waset.org/abstracts/search?q=pain%20control" title=" pain control"> pain control</a> </p> <a href="https://publications.waset.org/abstracts/163166/pain-control-by-ketamine-in-combat-situation-consideration-and-outcomes" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/163166.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">109</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">993</span> The Leaching Kinetics of Zinc from Industrial Zinc Slag Waste</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hilary%20Rutto">Hilary Rutto</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The investigation was aimed at determining the extent at which the zinc will be extracted from secondary sources generated from galvanising process using dilute sulphuric acid under controlled laboratory conditions of temperature, solid-liquid ratio, and agitation rate.

It is within the field of emergence the models of text, that can be potentially prognosticated in a certain communicative situation, are designated. Every text can be assumed as conceptual system structured on the base of certain communicative situation. However in the process of ‘structuring’ of a certain model of ‘conceptual system’ consciousness of a recipient is able act only within the border of the field of emergence for going out of this border indicates misunderstanding of the communicative situation. On the base of communicative situation we can witness the increment of meaning where the synergizing of the informative model of communication, formed by using of the invariant units of a language system, is a result of verbalization of the communicative situation. The potential of the models of a text, prognosticated within the field of emergence, also depends on the communicative situation. The conception ‘the field of emergence’ is interpreted as a unit of the language system, having poly-directed universal structure, implying the presence of the core, the center and the periphery, including different levels of means of a functioning system of language, both in terms of linguistic resources, and in terms of extra linguistic factors interaction of which results increment of a text. The conception ‘field of emergence’ is considered as the most promising in the analysis of texts: oral, written, printed and electronic. As a unit of the language system field of emergence has several properties that predict its use during the study of a text in different levels. This work is an attempt analysis of entropy in a text in the aspect of lingua-cultural code, prognosticated within the model of the field of emergence. The article describes the problem of entropy in the field of emergence, caused by influence of the extra-linguistic factors. The increasing of entropy is caused not only by the fact of intrusion of the language resources but by influence of the alien culture in a whole, and by appearance of non-typical for this very culture symbols in the field of emergence. The borrowing of alien lingua-cultural symbols into the lingua-culture of the author is a reason of increasing the entropy when constructing a text both in meaning and in structuring level. It is nothing but artificial formatting of lexical units that violate stylistic unity of a phrase. It is marked that one of the important characteristics descending the entropy in the field of emergence is a typical similarity of lexical and semantic resources of the different lingua-cultures in aspects of extra linguistic factors. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=communicative%20situation" title="communicative situation">communicative situation</a>, <a href="https://publications.waset.org/abstracts/search?q=field%20of%20emergence" title=" field of emergence"> field of emergence</a>, <a href="https://publications.waset.org/abstracts/search?q=lingua-culture" title=" lingua-culture"> lingua-culture</a>, <a href="https://publications.waset.org/abstracts/search?q=entropy" title=" entropy"> entropy</a> </p> <a href="https://publications.waset.org/abstracts/36560/entropy-in-a-field-of-emergence-in-an-aspect-of-linguo-culture" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/36560.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">368</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">989</span> Music Listening in Dementia: Current Developments and the Potential for Automated Systems in the Home: Scoping Review and Discussion</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Alexander%20Street">Alexander Street</a>, <a href="https://publications.waset.org/abstracts/search?q=Nina%20Wollersberger"> Nina Wollersberger</a>, <a href="https://publications.waset.org/abstracts/search?q=Paul%20Fernie"> Paul Fernie</a>, <a href="https://publications.waset.org/abstracts/search?q=Leonardo%20Muller"> Leonardo Muller</a>, <a href="https://publications.waset.org/abstracts/search?q=Ming%20Hung%20HSU"> Ming Hung HSU</a>, <a href="https://publications.waset.org/abstracts/search?q=Helen%20Odell-Miller"> Helen Odell-Miller</a>, <a href="https://publications.waset.org/abstracts/search?q=Jorg%20Fachner"> Jorg Fachner</a>, <a href="https://publications.waset.org/abstracts/search?q=Patrizia%20Di%20Campli%20San%20Vito"> Patrizia Di Campli San Vito</a>, <a href="https://publications.waset.org/abstracts/search?q=Stephen%20Brewster"> Stephen Brewster</a>, <a href="https://publications.waset.org/abstracts/search?q=Hari%20Shaji"> Hari Shaji</a>, <a href="https://publications.waset.org/abstracts/search?q=Satvik%20Venkatesh"> Satvik Venkatesh</a>, <a href="https://publications.waset.org/abstracts/search?q=Paolo%20Itaborai"> Paolo Itaborai</a>, <a href="https://publications.waset.org/abstracts/search?q=Nicolas%20Farina"> Nicolas Farina</a>, <a href="https://publications.waset.org/abstracts/search?q=Alexis%20Kirke"> Alexis Kirke</a>, <a href="https://publications.waset.org/abstracts/search?q=Sube%20Banerjee"> Sube Banerjee</a>, <a href="https://publications.waset.org/abstracts/search?q=Eduardo%20Reck%20Miranda"> Eduardo Reck Miranda</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Escalating neuropsychiatric symptoms (NPS) in people with dementia may lead to earlier care home admission. Music listening has been reported to stimulate cognitive function, potentially reducing agitation in this population. We present a scoping review, reporting on current developments and discussing the potential for music listening with related technology in managing agitation in dementia care. Of two searches for music listening studies, one focused on older people or people living with dementia where music listening interventions, including technology, were delivered in participants’ homes or in institutions to address neuropsychiatric symptoms, quality of life and independence. The second included any population focusing on the use of music technology for health and wellbeing. In search one 70/251 full texts were included. The majority reported either statistical significance (6, 8.5%), significance (17, 24.2%) or improvements (26, 37.1%). Agitation was specifically reported in 36 (51.4%). The second search included 51/99 full texts, reporting improvement (28, 54.9%), significance (11, 21.5%), statistical significance (1, 1.9%) and no difference compared to the control (6, 11.7%). The majority in the first focused on mood and agitation, and the second on mood and psychophysiological responses. Five studies used AI or machine learning systems to select music, all involving healthy controls and reporting benefits. Most studies in both reviews were not conducted in a home environment (review 1 = 12; 17.1%; review 2 = 11; 21.5%). Preferred music listening may help manage NPS in the care home settings. Based on these and other data extracted in the review, a reasonable progression would be to co-design and test music listening systems and protocols for NPS in all settings, including people’s homes. Machine learning and automated technology for music selection and arousal adjustment, driven by live biodata, have not been explored in dementia care. Such approaches may help deliver the right music at the appropriate time in the required dosage, reducing the use of medication and improving quality of life. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=music%20listening" title="music listening">music listening</a>, <a href="https://publications.waset.org/abstracts/search?q=dementia" title=" dementia"> dementia</a>, <a href="https://publications.waset.org/abstracts/search?q=agitation" title=" agitation"> agitation</a>, <a href="https://publications.waset.org/abstracts/search?q=scoping%20review" title=" scoping review"> scoping review</a>, <a href="https://publications.waset.org/abstracts/search?q=technology" title=" technology"> technology</a> </p> <a href="https://publications.waset.org/abstracts/164158/music-listening-in-dementia-current-developments-and-the-potential-for-automated-systems-in-the-home-scoping-review-and-discussion" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/164158.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">118</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">988</span> The Fidget Widget Toolkit: A Positive Intervention Designed and Evaluated to Enhance Wellbeing for People in the Later Stage of Dementia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jane%20E.%20Souyave">Jane E.

It is hoped that the tools will fulfill the possible needs of engagement and interaction as dementia progresses, therefore enhancing wellbeing and improving quality of life for the person with dementia and their carers. The project was informed by Kitwood’s five psychological needs for producing wellbeing and explored evidence that fidgeting is often seen as a form of agitation and a negative symptom of dementia. Although therapy for agitation may be well established, there is a lack of appropriate items aimed at people in the later stage of dementia, that are not childlike or medical in their aesthetic. Individuals may fidget in a particular way and the tools in the Fidget Widget Toolkit have been designed to encourage repetitive movements of the hand, specifically to address the abilities of people with relatively advanced dementia. As an intervention, these tools provided a new approach that had not been tested in dementia care. Prototypes were created through an iterative design process and tested with a number of people with dementia and their carers, using quantitative and qualitative methods. Dementia Care Mapping was used to evaluate the impact of the intervention in group settings. Cohen Mansfield’s Agitation Inventory was used to record the daily use and interest of the intervention for people in their usual place of residence. The results informed the design of a new set of devices to promote safe, stigma free fidgeting as a positive experience, meaningful activity and enhance wellbeing for people in the later stage of dementia. The outcomes addressed the needs of individuals by reducing agitation and restlessness through helping them to connect, engage and act independently, providing the means of doing something for themselves that they were able to do. The next stage will be to explore the commercial feasibility of the Fidget Widget Toolkit so that it can be introduced as good practice and innovation in dementia care. It could be used by care homes, with carers and their families to support wellbeing and lead the way in providing some positive experiences and person-centred approaches that are lacking in the later stage of dementia. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=dementia" title="dementia">dementia</a>, <a href="https://publications.waset.org/abstracts/search?q=design" title=" design"> design</a>, <a href="https://publications.waset.org/abstracts/search?q=fidgeting" title=" fidgeting"> fidgeting</a>, <a href="https://publications.waset.org/abstracts/search?q=healthcare" title=" healthcare"> healthcare</a>, <a href="https://publications.waset.org/abstracts/search?q=positive%20moments" title=" positive moments"> positive moments</a>, <a href="https://publications.waset.org/abstracts/search?q=quality%20of%20life" title=" quality of life"> quality of life</a>, <a href="https://publications.waset.org/abstracts/search?q=wellbeing" title=" wellbeing"> wellbeing</a> </p> <a href="https://publications.waset.org/abstracts/70505/the-fidget-widget-toolkit-a-positive-intervention-designed-and-evaluated-to-enhance-wellbeing-for-people-in-the-later-stage-of-dementia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/70505.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">277</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">987</span> Patient Agitation and Violence in Medical-Surgical Settings at BronxCare Hospital, Before and During COVID-19 Pandemic; A Retrospective Chart Review</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Soroush%20Pakniyat-Jahromi">Soroush Pakniyat-Jahromi</a>, <a href="https://publications.waset.org/abstracts/search?q=Jessica%20Bucciarelli"> Jessica Bucciarelli</a>, <a href="https://publications.waset.org/abstracts/search?q=Souparno%20Mitra"> Souparno Mitra</a>, <a href="https://publications.waset.org/abstracts/search?q=Neda%20Motamedi"> Neda Motamedi</a>, <a href="https://publications.waset.org/abstracts/search?q=Ralph%20Amazan"> Ralph Amazan</a>, <a href="https://publications.waset.org/abstracts/search?q=Samuel%20Rothman"> Samuel Rothman</a>, <a href="https://publications.waset.org/abstracts/search?q=Jose%20Tiburcio"> Jose Tiburcio</a>, <a href="https://publications.waset.org/abstracts/search?q=Douglas%20Reich"> Douglas Reich</a>, <a href="https://publications.waset.org/abstracts/search?q=Vicente%20Liz"> Vicente Liz</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Violence is defined as an act of physical force that is intended to cause harm and may lead to physical and/or psychological damage. Violence toward healthcare workers (HCWs) is more common in psychiatric settings, emergency departments, and nursing homes; however, healthcare workers in medical setting are not spared from such events. Workplace violence has a huge burden in the healthcare industry and has a major impact on the physical and mental wellbeing of staff. The purpose of this study is to compare the prevalence of patient agitation and violence in medical-surgical settings in BronxCare Hospital (BCH) Bronx, New York, one year before and during the COVID-19 pandemic. Data collection occurred between June 2021 and August 2021, while the sampling time was from 2019 to 2021. The data were separated into two separate time categories: pre-COVID-19 (03/2019-03/2020) and COVID-19 (03/2020-03/2021). We created frequency tables for 19 variables. We used a chi-square test to determine a variable's statistical significance. We tested all variables against “restraint type”, determining if a patient was violent or became violent enough to restrain. The restraint types were “chemical”, “physical”, or both. This analysis was also used to determine if there was a statistical difference between the pre-COVID-19 and COVID-19 timeframes. Our data shows that there was an increase in incidents of violence in COVID-19 era (03/2020-03/2021), with total of 194 (62.8%) reported events, compared to pre COVID-19 era (03/2019-03/2020) with 115 (37.2%) events (p: 0.01). Our final analysis, completed using a chi-square test, determined the difference in violence in patients between pre-COVID-19 and COVID-19 era. We then tested the violence marker against restraint type. The result was statistically significant (p: 0.01). This is the first paper to systematically review the prevalence of violence in medical-surgical units in a hospital in New York, pre COVID-19 and during the COVID-19 era. Our data is in line with the global trend of increased prevalence of patient agitation and violence in medical settings during the COVID-19 pandemic. Violence and its management is a challenge in healthcare settings, and the COVID-19 pandemic has brought to bear a complexity of circumstances, which may have increased its incidence. It is important to identify and teach healthcare workers the best preventive approaches in dealing with patient agitation, to decrease the number of restraints in medical settings, and to create a less restrictive environment to deliver care. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=COVID-19%20pandemic" title="COVID-19 pandemic">COVID-19 pandemic</a>, <a href="https://publications.waset.org/abstracts/search?q=patient%20agitation" title=" patient agitation"> patient agitation</a>, <a href="https://publications.waset.org/abstracts/search?q=restraints" title=" restraints"> restraints</a>, <a href="https://publications.waset.org/abstracts/search?q=violence" title=" violence"> violence</a> </p> <a href="https://publications.waset.org/abstracts/160499/patient-agitation-and-violence-in-medical-surgical-settings-at-bronxcare-hospital-before-and-during-covid-19-pandemic-a-retrospective-chart-review" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/160499.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">149</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">986</span> Arsenite Remediation by Green Nano Zero Valent Iron</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ratthiwa%20Deewan">Ratthiwa Deewan</a>, <a href="https://publications.waset.org/abstracts/search?q=Visanu%20Tanboonchuy"> Visanu Tanboonchuy</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The optimal conditions for green synthesis of zero-valent (G-NZVI) synthesis are investigated in this study using a Box Behnken design.

Three replicates of 20 seeds were germinated between double layered rolled germination papers in the Petri plates. Seeds were allowed to germinate at 20±1°C in the dark for 8 days. The seeds were counted on the 8th day as per ISTA rules and calculated in percent to determine germination capacity. Seedling emergency values were determined by testing 20 seeds placed into the sands with three replications of pots. Plants were counted on the 7th day and 12th day to determined seedling emergency rate and capacity, respectively. According to results, there are significant differences among the varieties in terms of germination capacity, seedling emergency rate and capacity of long-term stored and non-stored seeds. Germination capacity values declined from 100% to 93,3% of non-stored seeds whereas they were from 96,7% to 71,7% of long-term stored seeds. Percentage of seedling emergency capacity varied from 65,0% to 93,3% for non-stored seeds, however, the percentage of it was between 11,7 and 86,7% for long-term stored seeds. Results indicate that germination and emergence values responses to long-term stored condition varied significantly among durum wheat cultivars. Research results showed that the long-term-storage resulted in significant decrease with 13.5 % for germination, 36.4 % for emergence on the seventh day and 32.4 % for emergence on the twelfth day. Germination values ranged from 93.3 to 100.0 % for control and 71.7 to 96.7 % for storage. Emergence values in seventh day varied between 51.7 % and 90.0 % for control and 75.0 % and 10.0 % for storage, however values in twelfth day were between 93.3 % and 65.0 % for control and 86.7 % and 11.7 % for storage. According to research results, germination and emergence responses to long-term storage condition varied significantly among durum wheat cultivars. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=germination" title="germination">germination</a>, <a href="https://publications.waset.org/abstracts/search?q=emergence" title=" emergence"> emergence</a>, <a href="https://publications.waset.org/abstracts/search?q=long-term-storage" title=" long-term-storage"> long-term-storage</a>, <a href="https://publications.waset.org/abstracts/search?q=durum%20wheat" title=" durum wheat"> durum wheat</a> </p> <a href="https://publications.waset.org/abstracts/43319/responses-to-germination-and-seedling-emergence-capacity-of-durum-wheat-cultivars-in-long-term-storage" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/43319.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">363</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">984</span> Laboratory Scale Purification of Water from Copper Waste</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mumtaz%20Khan">Mumtaz Khan</a>, <a href="https://publications.waset.org/abstracts/search?q=Adeel%20Shahid"> Adeel Shahid</a>, <a href="https://publications.waset.org/abstracts/search?q=Waqas%20Khan"> Waqas Khan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Heavy metals presence in water streams is a big danger for aquatic life and ultimately effects human health. Removal of copper (Cu) by ispaghula husk, maize fibre, and maize oil cake from synthetic solution in batch conditions was studied. Different experimental parameters such as contact time, initial solution pH, agitation rate, initial Cu concentration, biosorbent concentration, and biosorbent particle size has been studied to quantify the Cu biosorption. The rate of adsorption of metal ions was very fast at the beginning and became slow after reaching the saturation point, followed by a slower active metabolic uptake of metal ions into the cells. Up to a certain point, (pH=4, concentration of Cu = ~ 640 mg/l, agitation rate = ~ 400 rpm, biosorbent concentration = ~ 0.5g, 3g, 3g for ispaghula husk, maize fiber and maize oil cake, respectively) increasing the pH, concentration of Cu, agitation rate, and biosorbent concentration, increased the biosorption rate; however the sorption capacity increased by decreasing the particle size. At optimized experimental parameters, the maximum Cu biosorption by ispaghula husk, maize fibre and maize oil cake were 86.7%, 59.6% and 71.3%, respectively. Moreover, the results of the kinetics studies demonstrated that the biosorption of copper on ispaghula husk, maize fibre, and maize oil cake followed pseudo-second order kinetics. The results of adsorption were fitted to both the Langmuir and Freundlich models. The Langmuir model represented the sorption process better than Freundlich, and R² value ~ 0.978. Optimizations of physical and environmental parameters revealed, ispaghula husk as more potent copper biosorbent than maize fibre, and maize oil cake. The sorbent is cheap and available easily, so this study can be applied to remove Cu impurities on pilot and industrial scale after certain modifications. <p
