The simulations are aimed at getting a better understanding of the pathophysiological flow patterns in an OSA patient. The simulation is compared to medical data of a sleep endoscopic examination under sedation. A digital model consisting of surface triangles of the upper airway is extracted from the MR images by a region growing segmentation process and is followed by a careful manual refinement. The computational domain includes the nasal cavity with the nostrils as the inlet areas and the pharyngeal volume with an outlet underneath the larynx. At the nostrils a flat inflow velocity profile is prescribed by choosing the velocity such that a volume flow rate of 150 ml/s is reached. Behind the larynx at the outlet a pressure of -10 Pa is prescribed. The stationary incompressible Navier-Stokes equations are numerically solved using finite elements. A grid convergence study has been performed. The results show an amplification of the maximal velocity of about 2.5 times the inlet velocity at a constriction of the pharyngeal volume in the area of the tongue. It is the same region that also shows the highest pressure drop from about 5 Pa. This is in agreement with the sleep endoscopic examinations of the same patient under sedation showing complete contractions in the area of the tongue. CFD simulations can become a useful tool in the diagnosis and therapy of obstructive sleep apnea by giving insight into the patient’s individual fluid dynamical situation in the upper airways giving a better understanding of the disease where experimental measurements are not feasible. Within this study, it could been shown on one hand that constriction areas within the upper airway lead to a significant pressure drop and on the other hand a good agreement of the area of pressure drop and the area of contraction could be shown. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biomedical%20engineering" title="biomedical engineering">biomedical engineering</a>, <a href="https://publications.waset.org/abstracts/search?q=obstructive%20sleep%20apnea" title=" obstructive sleep apnea"> obstructive sleep apnea</a>, <a href="https://publications.waset.org/abstracts/search?q=pharynx" title=" pharynx"> pharynx</a>, <a href="https://publications.waset.org/abstracts/search?q=upper%20airways" title=" upper airways"> upper airways</a> </p> <a href="https://publications.waset.org/abstracts/67739/cfd-simulation-of-the-pressure-distribution-in-the-upper-airway-of-an-obstructive-sleep-apnea-patient" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/67739.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">306</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">1221</span> Study for a Non-Invasive Method of Respiratory Resistance Measurement among Patients with Airways Obstructions</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Aicha%20Laouani">Aicha Laouani</a>, <a href="https://publications.waset.org/abstracts/search?q=Pascale%20Calabrese"> Pascale Calabrese</a>, <a href="https://publications.waset.org/abstracts/search?q=Sonia%20Rouatbi"> Sonia Rouatbi</a>, <a href="https://publications.waset.org/abstracts/search?q=Saad%20Saguem"> Saad Saguem</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Distances between signals (S d) and between asters (A d) calculated from respiratory inductive plethysmography signals has been used in order to evaluation airways resistances (Raw) during reversibility test among 28 subject with airways obstructions.

The population of this study was Thai passengers flying domestic flights with Thai Airways, making a total of 300 samples. These 300 samples participated in this research by answering a collection of questions by means of a questionnaire. An analysis of means score and multiple regression revealed that perceived service quality for tangible elements, reliability, responsiveness, assurance and empathy had determined repeated purchase of flight service of the passengers at a high level. Moreover, reliability and responsiveness factors could predict the passengers’ repeated purchase of flight service at the percentage of 30.6. The findings gave a signal that Thai Airways may consider a development of route network and fleet strategy as well as an establishment of aircraft and seat qualification to meet passengers’ needs and requirements. Passengers’ level of satisfaction could also be maximized by offering service value through various kinds of special deals and programs, whereas value- added pricing strategy should be considered in order to differentiate from and beat other leading airline competitors. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=repeated%20purchase" title="repeated purchase">repeated purchase</a>, <a href="https://publications.waset.org/abstracts/search?q=service%20quality" title=" service quality"> service quality</a>, <a href="https://publications.waset.org/abstracts/search?q=domestic%20flight" title=" domestic flight"> domestic flight</a>, <a href="https://publications.waset.org/abstracts/search?q=Thai%20Airways" title=" Thai Airways"> Thai Airways</a> </p> <a href="https://publications.waset.org/abstracts/8124/determinants-of-service-quality-on-thai-passengers-repeated-purchase-of-domestic-flight-service-with-thai-airways-international" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/8124.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">1219</span> Study of a Complete Free Route Implementation in the European Airspace</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Cesar%20A.%20Nava-Gaxiola">Cesar A.

Barrado</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Harmonized with SESAR (Single European Sky Research) initiatives, a new concept related with airspace structures have been introduced in Europe, the Free Route Airspace. The key of free route is based in an airspace where users may freely plan a route between a defined entry and exit waypoint, with the possibility of routing via intermediate points, the free route flights remain subject to air traffic control (ATC) for the established separations. Free route airspace does not present anymore fixed airways to airspace users, as a consequence it brings a new paradigm for managing safe separations of aircrafts inside these airspace blocks . Nowadays, several European nations have been introduced the concept, some of them in a complete or partial stage, but finally offering limited benefits to airspace users for this condition. This research evaluates the future scenario of free route implementation across Europe, considering a unique airspace block configuration with a complete upper airspace with free route. The paper is centered in investigating the benefits for airspace users, and the study of possible increments of Air Traffic Controllers task loads with a full application. In this research, fast time simulations are carrying out for discovering how much flight time and distance aircrafts can save with an overall free route establishment. In the other side, the paper explains the evolution of conflicts derivate from possible separation losses between aircrafts in this new environment. Free route conflicts can emerges in any points of the airspace, requiring a great effort for solving it, in comparison with fixed airways, where conflicts normally were found by controllers in known waypoints, and they solved using the fixed network as reference. The airspace configuration modelled in this study take into account the actual navigation waypoints structure, moving into a future scenario, where new ones waypoints are added and new traffic flow patterns appears. In this sense, this research explores the advantages and unknown difficulties that a large scale application of free route concept can carry out in the European airspace. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ATC%20conflicts" title="ATC conflicts">ATC conflicts</a>, <a href="https://publications.waset.org/abstracts/search?q=efficiency" title=" efficiency"> efficiency</a>, <a href="https://publications.waset.org/abstracts/search?q=free%20route%20airspace" title=" free route airspace"> free route airspace</a>, <a href="https://publications.waset.org/abstracts/search?q=SESAR" title=" SESAR"> SESAR</a> </p> <a href="https://publications.waset.org/abstracts/81131/study-of-a-complete-free-route-implementation-in-the-european-airspace" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/81131.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">188</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">1218</span> Effective Virtual Tunnel Shape for Motion Modification in Upper-Limb Perception-Assist with a Power-Assist Robot</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kazuo%20Kiguchi">Kazuo Kiguchi</a>, <a href="https://publications.waset.org/abstracts/search?q=Kouta%20Ikegami"> Kouta Ikegami</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In the case of physically weak persons, not only motor abilities, but also sensory abilities are sometimes deteriorated. The concept of perception-assist has been proposed to assist the sensory ability of the physically weak persons with a power-assist robot. Since upper-limb motion is very important in daily living, perception-assist for upper-limb motion has been proposed to assist upper-limb motion in daily living. A virtual tunnel was applied to modify the user’s upper-limb motion if it was necessary. In this paper, effective shape of the virtual tunnel which is applied in the perception-assist for upper-limb motion is proposed. Not only the position of the grasped tool but also the angle of the grasped tool are modified if it is necessary. Therefore, the upper-limb motion in daily living can be effectively modified to realize certain proper daily motion. The effectiveness of the proposed virtual tunnel was evaluated by performing the experiments. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=motion%20modification" title="motion modification">motion modification</a>, <a href="https://publications.waset.org/abstracts/search?q=power-assist%20robots" title=" power-assist robots"> power-assist robots</a>, <a href="https://publications.waset.org/abstracts/search?q=perception-assist" title=" perception-assist"> perception-assist</a>, <a href="https://publications.waset.org/abstracts/search?q=upper-limb%20motion" title=" upper-limb motion"> upper-limb motion</a> </p> <a href="https://publications.waset.org/abstracts/53101/effective-virtual-tunnel-shape-for-motion-modification-in-upper-limb-perception-assist-with-a-power-assist-robot" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/53101.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">241</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">1217</span> Estimation of the Upper Tail Dependence Coefficient for Insurance Loss Data Using an Empirical Copula-Based Approach</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Adrian%20O%27Hagan">Adrian O'Hagan</a>, <a href="https://publications.waset.org/abstracts/search?q=Robert%20McLoughlin"> Robert McLoughlin</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Considerable focus in the world of insurance risk quantification is placed on modeling loss values from lines of business (LOBs) that possess upper tail dependence. Copulas such as the Joe, Gumbel and Student-t copula may be used for this purpose. The copula structure imparts a desired level of tail dependence on the joint distribution of claims from the different LOBs. Alternatively, practitioners may possess historical or simulated data that already exhibit upper tail dependence, through the impact of catastrophe events such as hurricanes or earthquakes. In these circumstances, it is not desirable to induce additional upper tail dependence when modeling the joint distribution of the loss values from the individual LOBs. Instead, it is of interest to accurately assess the degree of tail dependence already present in the data. The empirical copula and its associated upper tail dependence coefficient are presented in this paper as robust, efficient means of achieving this goal. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=empirical%20copula" title="empirical copula">empirical copula</a>, <a href="https://publications.waset.org/abstracts/search?q=extreme%20events" title=" extreme events"> extreme events</a>, <a href="https://publications.waset.org/abstracts/search?q=insurance%20loss%20reserving" title=" insurance loss reserving"> insurance loss reserving</a>, <a href="https://publications.waset.org/abstracts/search?q=upper%20tail%20dependence%20coefficient" title=" upper tail dependence coefficient"> upper tail dependence coefficient</a> </p> <a href="https://publications.waset.org/abstracts/2645/estimation-of-the-upper-tail-dependence-coefficient-for-insurance-loss-data-using-an-empirical-copula-based-approach" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/2645.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">284</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">1216</span> Nutrient Foramina in the Shaft of Long Bones of Upper Limb</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Madala%20Venkateswara%20Rao">Madala Venkateswara Rao</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The major blood supply to the long bones occurs through the nutrient arteries, which enters through the nutrient foramina. This is the study of nutrient Foramina in the shaft of upper limb long bones taken from the department of Anatomy at Narayana medical college nellore. Nutrient foramina play an important role in nutrition and growth of the bones. Most of the nutrient arteries follow the rule, 'to the elbow I go, from the knee I flee' but they are very variable in position. Their number, location, direction & its importance in the growing end of long bones were studied in the long bones of upper limb. The present study has variations in the position & direction of long bones especially in the radius & ulna, as most of the nutrient foramina are found in anterior surface of upper 1/3rd and middle 1/3rd of these bones. The study of nutrient foramina is not only of academic interest but also in medico-legal practice in relation to their position. Careful observation has also been made on the position of nutrient foramina in relation to upper end of long bones. This study also gives importance of length long bones to know the height of an individual. With the knowledge of variations in the nutrient foramen, placement of internal fixation devices can be appropriately done. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=nutrient%20artery" title="nutrient artery">nutrient artery</a>, <a href="https://publications.waset.org/abstracts/search?q=nutrient%20foramina" title=" nutrient foramina"> nutrient foramina</a>, <a href="https://publications.waset.org/abstracts/search?q=shaft%20of%20long%20bones" title=" shaft of long bones"> shaft of long bones</a>, <a href="https://publications.waset.org/abstracts/search?q=upper%20limb%20bones" title=" upper limb bones"> upper limb bones</a> </p> <a href="https://publications.waset.org/abstracts/42312/nutrient-foramina-in-the-shaft-of-long-bones-of-upper-limb" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/42312.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">502</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">1215</span> Formulating Rough Approximations in Information Tables with Possibilistic Information</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Michinori%20Nakata">Michinori Nakata</a>, <a href="https://publications.waset.org/abstracts/search?q=Hiroshi%20Sakai"> Hiroshi Sakai</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A rough set, which consists of lower and upper approximations, is formulated in information tables containing possibilistic information. First, lower and upper approximations on the basis of possible world semantics in the same way as Lipski did in the field of incomplete databases are shown in order to clarify fundamentals of rough sets under possibilistic information. Possibility and necessity measures are used, as is done in possibilistic databases. As a result, each object has certain and possible membership degrees to lower and upper approximations, which degrees are the lower and upper bounds. Therefore, the degree that the object belongs to lower and upper approximations is expressed by an interval value. And the complementary property linked with the lower and upper approximations holds, as is valid under complete information. Second, the approach based on indiscernibility relations, which is proposed by Dubois and Prade, are extended in three cases. The first case is that objects used to approximate a set of objects are characterized by possibilistic information. The second case is that objects used to approximate a set of objects with possibilistic information are characterized by complete information.

The extended approach create the same results as the approach based on possible world semantics.

It is identified as a biological multifunctional messenger molecule which is synthesized by the action of nitric oxide synthase (NOS) enzyme from L-arginine. The protective and the toxic effect in conjunction form the complete picture of the biological function of nitric oxide in humans. The dual nature is because of various factors such as concentration of NO, the isoform of NOS involved, type of cells in which it is synthesized, reaction partners like proteins, reactive oxygen intermediates, prosthetic groups, thiols etc., availability of the substrate L-arginine, intracellular environment in which NO is produced and generation of guanosine 3, 5’- cyclic monophosphate (cGMP). Activation of NOS through infection or trauma leads to one or more systemic effects including enhanced immune activity against invading pathogens, vaso/bronchodilatation in the cardiovascular and respiratory systems and altered neurotransmission which can be protective or toxic. Hence, NO affects the balance between healthy signaling and neurodegeneration in the brain. In lungs, it has beneficial effects on the function of airways as a bronchodilator and acts as the neurotransmitter of bronchodilator nerves. Whereas, on the other hand, NO may have deleterious effects by amplifying the asthmatic inflammatory response and also act as a vasodilator in the airways by increasing plasma exudation. But NOS Inhibitors and NO donors hamper the signalling pathway and hence a therapeutic application of NO is compromised. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=nitric%20oxide" title="nitric oxide">nitric oxide</a>, <a href="https://publications.waset.org/abstracts/search?q=multifunctional" title=" multifunctional"> multifunctional</a>, <a href="https://publications.waset.org/abstracts/search?q=dual%20nature" title=" dual nature"> dual nature</a>, <a href="https://publications.waset.org/abstracts/search?q=therapeutic%20applications" title=" therapeutic applications"> therapeutic applications</a> </p> <a href="https://publications.waset.org/abstracts/21561/nitric-oxide-role-in-immunity-and-therapeutics" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/21561.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">498</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">1212</span> Statistical Shape Analysis of the Human Upper Airway</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ramkumar%20Gunasekaran">Ramkumar Gunasekaran</a>, <a href="https://publications.waset.org/abstracts/search?q=John%20Cater"> John Cater</a>, <a href="https://publications.waset.org/abstracts/search?q=Vinod%20Suresh"> Vinod Suresh</a>, <a href="https://publications.waset.org/abstracts/search?q=Haribalan%20Kumar"> Haribalan Kumar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The main objective of this project is to develop a statistical shape model using principal component analysis that could be used for analyzing the shape of the human airway. The ultimate goal of this project is to identify geometric risk factors for diagnosis and management of Obstructive Sleep Apnoea (OSA). Anonymous CBCT scans of 25 individuals were obtained from the Otago Radiology Group. The airways were segmented between the hard-palate and the aryepiglottic fold using snake active contour segmentation. The point data cloud of the segmented images was then fitted with a bi-cubic mesh, and pseudo landmarks were placed to perform PCA on the segmented airway to analyze the shape of the airway and to find the relationship between the shape and OSA risk factors. From the PCA results, the first four modes of variation were found to be significant. Mode 1 was interpreted to be the overall length of the airway, Mode 2 was related to the anterior-posterior width of the retroglossal region, Mode 3 was related to the lateral dimension of the oropharyngeal region and Mode 4 was related to the anterior-posterior width of the oropharyngeal region. All these regions are subjected to the risk factors of OSA. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=medical%20imaging" title="medical imaging">medical imaging</a>, <a href="https://publications.waset.org/abstracts/search?q=image%20processing" title=" image processing"> image processing</a>, <a href="https://publications.waset.org/abstracts/search?q=FEM%2FBEM" title=" FEM/BEM"> FEM/BEM</a>, <a href="https://publications.waset.org/abstracts/search?q=statistical%20modelling" title=" statistical modelling"> statistical modelling</a> </p> <a href="https://publications.waset.org/abstracts/83934/statistical-shape-analysis-of-the-human-upper-airway" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/83934.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">514</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">1211</span> Model Free Terminal Sliding Mode with Gravity Compensation: Application to an Exoskeleton-Upper Limb System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sana%20Bembli">Sana Bembli</a>, <a href="https://publications.waset.org/abstracts/search?q=Nahla%20Khraief%20Haddad"> Nahla Khraief Haddad</a>, <a href="https://publications.waset.org/abstracts/search?q=Safya%20Belghith"> Safya Belghith</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper deals with a robust model free terminal sliding mode with gravity compensation approach used to control an exoskeleton-upper limb system.

Nineteen people, comprising fifteen young, healthy individuals, two middle-aged individuals, and two individuals with dysfunctions, were analyzed using the movement analysis system. Proposed parameters such as ASᵢₐ (reflecting the arm swing amplitude) and Pearson’s correlation coefficient between the right and left upper limbs can be used to classify the type of movement task each participant performs.

Laffont</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: After a cerebrovascular accident (or stroke), many patients use excessive trunk movements to move their paretic hand towards a target (while the elbow is maintained flexed) even though they can use the upper-limb when the trunk is restrained. This phenomenon is labelled learned non-use and is known to be detrimental to neuroplasticity and recovery. Objective: The aim of this study is to quantify learned non-use of the paretic upper limb during a hand reaching task using 3D movement analysis. Methods: Thirty-four participants post supratentorial stroke were asked to reach a cone placed in front of them at 80% of their arm length. The reaching movement was repeated 5 times with the paretic hand, and then 5 times with the less-impaired hand. This sequence was first performed with the trunk free, then with the trunk restrained. Learned non-use of the upper-limb (LNUUL) was obtained from the difference of the amount of trunk compensation between the free trunk condition and the restrained trunk condition. Results: LNUUL was significantly higher for the paretic hand, with individual values ranging from 1% to 43%, and one-half of the patients with an LNUUL higher than 15%. Conclusions: Quantification of LNUUL can be used to objectively diagnose patients who need trunk rehabilitation. It can be also used for monitoring the rehabilitation progress. Quantification of LNUUL may guide upper-limb rehabilitation towards more optimal motor recovery avoiding maladaptive trunk compensation and its consequences on neuroplasticity. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=learned%20non-use" title="learned non-use">learned non-use</a>, <a href="https://publications.waset.org/abstracts/search?q=rehabilitation" title=" rehabilitation"> rehabilitation</a>, <a href="https://publications.waset.org/abstracts/search?q=stroke" title=" stroke"> stroke</a>, <a href="https://publications.waset.org/abstracts/search?q=upper%20limb" title=" upper limb"> upper limb</a> </p> <a href="https://publications.waset.org/abstracts/32555/quantification-of-learned-non-use-of-the-upper-limb-after-a-stroke" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/32555.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">238</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">1208</span> Identification of Workplace Hazards of Underground Coal Mines</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Madiha%20Ijaz">Madiha Ijaz</a>, <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Akram"> Muhammad Akram</a>, <a href="https://publications.waset.org/abstracts/search?q=Sima%20Mir"> Sima Mir</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Underground mining of coal is carried out manually in Pakistan. Exposure to ergonomic hazards (musculoskeletal disorders) are very common among the coal cutters of these mines. Cutting coal in narrow spaces poses a great threat to both upper and lower limbs of these workers. To observe the prevalence of such hazards, a thorough study was conducted on 600 workers from 30 mines (20 workers from 1 mine), located in two districts of province Punjab, Pakistan. Rapid Upper Limb Assessment sheet and Rapid Entire Body Assessment sheet were used for the study along with a standard Nordic Musculoskeleton disorder questionnaire. SPSS, 25, software was used for data analysis on upper and lower limb disorders, and regression analysis models were run for upper and lower back pain. According to the results obtained, it was found that work stages (drilling & blasting, coal cutting, timbering & supporting, etc.), wok experience and number of repetitions performed/minute were significant (with p-value 0.00,0.004 and 0.009, respectively) for discomfort in upper and lower limb. Age got p vale 0.00 for upper limb and 0.012 for lower limb disorder. The task of coal cutting was strongly associated with the pain in upper back (with odd ratios13.21, 95% confidence interval (CI)14.0-21.64)) and lower back pain (3.7, 95% confidence interval 1.3-4.2). scored on RULA and REBA sheets, every work-stage was ranked at 7-highest level of risk involved.

The model can be utilized to investigate the flow behavior as the vessel combined with upper pool and continuity cooling system. At normal operating condition, different parameters are obtained for the full fluid area, including velocity, mass flow, and mixing phenomenon in the reactor pressure vessel (RPV) and upper pool.

The MACS defines bimanual hand abilities for children ages 4-18 years in everyday tasks and is a gradient scale, with I being nearly normal and V requiring total assistance. Children with more severe upper extremity impairment (MACS III-V) are often underrepresented, and relatively few effective therapies have been identified for these patients. Current orthoses are static and are only meant to prevent the progression of contractures in these patients. Other limitations include cost, comfort, accessibility, and longevity of the orthoses. Taking advantage of advances in 3D printing technology, we have created a highly customizable upper extremity orthotic that can be produced at a low cost. Iterations in our design have resulted in an orthotic that is custom fit to the patient based on scans of their arm, made of rigid polymer when needed to provide support, flexible material where appropriate to allow for comfort, and designed with a mechanical pulley system to allow for some functional use of the arm while in the orthotic. Preliminary data has shown that our orthotic can be built at a fraction of the cost of current orthoses and provide clinically significant improvement in assisting hand assessment (AHA) and pediatric quality of life scores (PedsQL). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=upper%20extremity%20orthosis" title="upper extremity orthosis">upper extremity orthosis</a>, <a href="https://publications.waset.org/abstracts/search?q=upper%20extremity" title=" upper extremity"> upper extremity</a>, <a href="https://publications.waset.org/abstracts/search?q=orthosis" title=" orthosis"> orthosis</a>, <a href="https://publications.waset.org/abstracts/search?q=3-D%20printing" title=" 3-D printing"> 3-D printing</a>, <a href="https://publications.waset.org/abstracts/search?q=cerebral%20palsy" title=" cerebral palsy"> cerebral palsy</a>, <a href="https://publications.waset.org/abstracts/search?q=occupational%20therapy" title=" occupational therapy"> occupational therapy</a>, <a href="https://publications.waset.org/abstracts/search?q=spasticity" title=" spasticity"> spasticity</a>, <a href="https://publications.waset.org/abstracts/search?q=customizable" title=" customizable"> customizable</a> </p> <a href="https://publications.waset.org/abstracts/144291/designing-and-using-a-3-d-printed-dynamic-upper-extremity-orthosis-dueo-with-children-with-cerebral-palsy-and-severe-upper-extremity-involvement" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/144291.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">307</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">1205</span> Late Pleistocene Raised Coral Reefs in Rabigh Area, Red Sea: Microfacies and Environmental Interpretation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ammar%20Manaa">Ammar Manaa</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The late Pleistocene raised coral reef terraces, 1 to 5 m above present sea level, are distinguished in Rabigh area into two marine terraces at elevations 0.5 m and 3.20 m, in addition to back-reef facies. The lower and upper terraces consist mainly of corals that increased in abundance and distribution in the upper terrace, with a minor occurrence of detrital quartz and feldspar. The back-reef facies consist mainly of coralline algae with a minor occurrence of corals. The upper terrace was interpreted as a reef crest or algal ridge due to the dominance of bindstone facies. The lower terrace indicates an outer reef flat with the occurrence of grainstone and rudstone facies. The coral framework in the upper terrace indicates a low energy environment. Within the back-reef terrace, calcareous mud was dominant, which indicates low energy, lagoon environment. The XRD results for the studied terraces revealed a variable abundance of aragonite, high-Mg calcite, and low-Mg calcite, with a slight increase in calcite and high-Mg calcite in the upper terrace. The dominant diagenetic processes in the terraces are cementation by fibrous and blocky calcite and dissolution that varied slightly between the lower and upper terraces. This study provides a coral reef model relevant to a low energy system in a dry and hot environment. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=late%20Pleistocene" title="late Pleistocene">late Pleistocene</a>, <a href="https://publications.waset.org/abstracts/search?q=Rabigh" title=" Rabigh"> Rabigh</a>, <a href="https://publications.waset.org/abstracts/search?q=reef%20terraces" title=" reef terraces"> reef terraces</a>, <a href="https://publications.waset.org/abstracts/search?q=Red%20Sea" title=" Red Sea"> Red Sea</a>, <a href="https://publications.waset.org/abstracts/search?q=Saudi%20Arabia." title=" Saudi Arabia."> Saudi Arabia.</a> </p> <a href="https://publications.waset.org/abstracts/120245/late-pleistocene-raised-coral-reefs-in-rabigh-area-red-sea-microfacies-and-environmental-interpretation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/120245.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">1204</span> Increasing Access to Upper Limb Reconstruction in Cervical Spinal Cord Injury</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Michelle%20Jennett">Michelle Jennett</a>, <a href="https://publications.waset.org/abstracts/search?q=Jana%20Dengler"> Jana Dengler</a>, <a href="https://publications.waset.org/abstracts/search?q=Maytal%20Perlman"> Maytal Perlman</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Cervical spinal cord injury (SCI) is a devastating event that results in upper limb paralysis, loss of independence, and disability. People living with cervical SCI have identified improvement of upper limb function as a top priority. Nerve and tendon transfer surgery has successfully restored upper limb function in cervical SCI but is not universally used or available to all eligible individuals. This exploratory mixed-methods study used an implementation science approach to better understand these factors that influence access to upper limb reconstruction in the Canadian context and design an intervention to increase access to care. Methods: Data from the Canadian Institute for Health Information’s Discharge Abstracts Database (CIHI-DAD) and the National Ambulatory Care Reporting System (NACRS) were used to determine the annual rate of nerve transfer and tendon transfer surgeries performed in cervical SCI in Canada over the last 15 years. Semi-structured interviews informed by the consolidated framework for implementation research (CFIR) were used to explore Ontario healthcare provider knowledge and practices around upper limb reconstruction. An inductive, iterative constant comparative process involving descriptive and interpretive analyses was used to identify themes that emerged from the data. Results: Healthcare providers (n = 10 upper extremity surgeons, n = 10 SCI physiatrists, n = 12 physical and occupational therapists working with individuals with SCI) were interviewed about their knowledge and perceptions of upper limb reconstruction and their current practices and discussions around upper limb reconstruction. Data analysis is currently underway and will be presented. Regional variation in rates of upper limb reconstruction and trends over time are also currently being analyzed. Conclusions: Utilization of nerve and tendon transfer surgery to improve upper limb reconstruction in Canada remains low. There are a complex array of interrelated individual-, provider- and system-level barriers that prevent individuals with cervical SCI from accessing upper limb reconstruction. In order to offer equitable access to care, a multi-modal approach addressing current barriers is required. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cervical%20spinal%20cord%20injury" title="cervical spinal cord injury">cervical spinal cord injury</a>, <a href="https://publications.waset.org/abstracts/search?q=nerve%20and%20tendon%20transfer%20surgery" title=" nerve and tendon transfer surgery"> nerve and tendon transfer surgery</a>, <a href="https://publications.waset.org/abstracts/search?q=spinal%20cord%20injury" title=" spinal cord injury"> spinal cord injury</a>, <a href="https://publications.waset.org/abstracts/search?q=upper%20extremity%20reconstruction" title=" upper extremity reconstruction"> upper extremity reconstruction</a> </p> <a href="https://publications.waset.org/abstracts/137972/increasing-access-to-upper-limb-reconstruction-in-cervical-spinal-cord-injury" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/137972.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">97</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">1203</span> Effects of Local Decongestive Agents at Trachea and Lungs</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sertac%20Arslan">Sertac Arslan</a>, <a href="https://publications.waset.org/abstracts/search?q=Guven%20Guney"> Guven Guney</a>, <a href="https://publications.waset.org/abstracts/search?q=Ayse%20Ipek%20Akyuz%20Unsal"> Ayse Ipek Akyuz Unsal</a>, <a href="https://publications.waset.org/abstracts/search?q=Emre%20Demir"> Emre Demir</a>, <a href="https://publications.waset.org/abstracts/search?q=Buket%20Demirci"> Buket Demirci</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Purpose: There is little histologic data concerning effects of nasal decongestants on the respiratory tract. We aimed to put forth the effects of nasal decongestants on the trachea and lower airways of rats. Materials and Methods: Four to six months old 60 male rats were randomly categorized into 6 groups. Experimental drugs were applied to the same nostril of rats twice daily for 8 weeks (Xylometazolin, Benzalkolyum, EDTA, Sorbitol and combined drug solutions). We applied normal saline solution (NaCl %0.9) for the control group. In the end, trachea and both lungs were dissected and kept in formaldehyde for histopathologic evaluation. Results: Inflammation and bronchial edema were most common findings. While all rats in sorbitol group had increased numbers of type 2 pneumocytes; 80% of BAC group had increased numbers of type 2 pneumocytes. Spillover of tracheal epithelium was seen mostly in sorbitol, EDTA and combined drug groups (60%, 87.5%, 50% respectively). Bronchial smooth muscle hypertrophy was seen mostly in BAC and EDTA group (70%, 62.5% respectively). The number of goblet cells showed the significant difference between control-combined drug (p=0.025) and control-BAC (p=0.001) groups. Conclusions: Nasal decongestants can cause permanent changes at lower respiratory tract in addition to changes in upper respiratory tract. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=decongestive%20agents" title="decongestive agents">decongestive agents</a>, <a href="https://publications.waset.org/abstracts/search?q=xylometazoline" title=" xylometazoline"> xylometazoline</a>, <a href="https://publications.waset.org/abstracts/search?q=lung" title=" lung"> lung</a>, <a href="https://publications.waset.org/abstracts/search?q=trachea" title=" trachea"> trachea</a> </p> <a href="https://publications.waset.org/abstracts/88759/effects-of-local-decongestive-agents-at-trachea-and-lungs" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/88759.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">176</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">1202</span> The Development of Community Leadership Strategies for Career Development of the Benjarong Pottery Products in Eight Upper Central Provinces </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Thanaporn%20Chaimongkol">Thanaporn Chaimongkol</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The objective of this research was aimed to examine the factors that influence the development of community leadership strategies to further develop the career regarding the Benjarong pottery products in eight upper central provinces, Thailand.

In such a case, an alternative to pile foundations may be shallow strip footings placed on a soil system in which the upper layer is untreated or cement-treated compacted sand to limit the settlement within a permissible level. This research work deals with a rigid plane-strain strip footing of 2.5m width placed on a soil consisting of untreated or cement treated sand layer underlain by homogeneous soft clay. Both the thin and thick compared the footing width was considered. The soft inorganic cohesive NC clay layer is considered undrained for plastic loading stages and drained in consolidation stages, and the sand layer is drained in all loading stages. FEM analysis was done using PLAXIS 2D Version 8.0 with a model consisting of clay deposits of 15m thickness and 18m width. The soft clay layer was modeled using the Hardening Soil Model, Soft Soil Model, Soft Soil Creep model, and the upper improvement layer was modeled using only the Hardening Soil Model. The system is considered fully saturated. The value of natural void ratio 1.2 is used. Total displacement fields of strip footing and subsoil layers in the case of Untreated and Cement treated Sand as Upper layer are presented. For Hi/B =0.6 or above, the distribution of major deformation within an upper layer and the influence zone of footing is limited in an upper layer which indicates the complete effectiveness of the upper layer in bearing the foundation effectively in case of the untreated upper layer. For Hi/B =0.3 or above, the distribution of major deformation occurred within an upper layer, and the function of footing is limited in the upper layer. This indicates the complete effectiveness of the cement-treated upper layer. Brittle behavior of cemented sand and fracture or cracks is not considered in this analysis. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=displacement" title="displacement">displacement</a>, <a href="https://publications.waset.org/abstracts/search?q=ground%20improvement" title=" ground improvement"> ground improvement</a>, <a href="https://publications.waset.org/abstracts/search?q=influence%20depth" title=" influence depth"> influence depth</a>, <a href="https://publications.waset.org/abstracts/search?q=PLAXIS%202D" title=" PLAXIS 2D"> PLAXIS 2D</a>, <a href="https://publications.waset.org/abstracts/search?q=primary%20and%20secondary%20settlement" title=" primary and secondary settlement"> primary and secondary settlement</a>, <a href="https://publications.waset.org/abstracts/search?q=sand%20mat" title=" sand mat"> sand mat</a>, <a href="https://publications.waset.org/abstracts/search?q=soft%20clay" title=" soft clay"> soft clay</a> </p> <a href="https://publications.waset.org/abstracts/149870/influence-zone-of-strip-footing-on-untreated-and-cement-treated-sand-mat-underlain-by-soft-clay-2nd-reviewed" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/149870.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">93</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">1199</span> Effects of ECCS on the Cold-Leg Fluid Temperature during SGTR Accidents</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tadashi%20Watanabe">Tadashi Watanabe</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The LSTF experiment simulating the SGTR accident at the Mihama Unit-2 reactor is analyzed using the RELAP5/MOD3.3 code.

These evaluations depended on the raters’ experiences. This initiated us to develop an upper limb disorder part-task trainer that is able to simulate consistent upper limb disorders, such as spasticity and rigidity signs, based on the Modified Ashworth Scale to improve the variability occurring between raters and intra-raters themselves. By providing consistent signs, novice therapists would be able to increase training frequency and exposure towards various levels of signs. A total of 22 physiotherapists and occupational therapists participated in the study. The majority of the therapists agreed that with current therapy education, they still face problems with inter-raters and intra-raters variability (strongly agree 54%; n = 12/22, agree 27%; n = 6/22) in evaluating patients’ conditions. The therapists strongly agreed (72%; n = 16/22) that therapy trainees needed to increase their frequency of training; therefore believe that our initiative to develop an upper limb disorder training tool will help in improving the clinical education field (strongly agree and agree 63%; n = 14/22). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=upper%20limb%20disorder" title="upper limb disorder">upper limb disorder</a>, <a href="https://publications.waset.org/abstracts/search?q=clinical%20education%20tool" title=" clinical education tool"> clinical education tool</a>, <a href="https://publications.waset.org/abstracts/search?q=inter%2Fintra-raters%20variability" title=" inter/intra-raters variability"> inter/intra-raters variability</a>, <a href="https://publications.waset.org/abstracts/search?q=spasticity" title=" spasticity"> spasticity</a>, <a href="https://publications.waset.org/abstracts/search?q=modified%20Ashworth%20scale" title=" modified Ashworth scale "> modified Ashworth scale </a> </p> <a href="https://publications.waset.org/abstracts/10949/a-questionnaire-based-survey-therapists-response-towards-upper-limb-disorder-learning-tool" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/10949.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">310</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">1196</span> Assessment of Hamstring, Lower Back and Upper Body Flexibility in War Disabled Individuals in Sri Lanka North and East Region</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Esther%20Liyanage">Esther Liyanage</a>, <a href="https://publications.waset.org/abstracts/search?q=Indrajith%20Liyanage"> Indrajith Liyanage</a>, <a href="https://publications.waset.org/abstracts/search?q=A.%20A.%20J.%20Rajaratne"> A.

These disabilities have reduced their daily physical activities which may cause reduction in flexibility of upper limb, shoulder girdle, lower back and lower limb. Muscle flexibility is important for a healthy lifestyle. The main objective of the study was to assess the upper limb, shoulder girdle and lower back, hamstring flexibility of the intact lower limb in disabled individuals in the North and Eastern parts of Sri Lanka. Back saver sits and reach test and shoulder scratch test described in FITNESS GRAM was used in the study. A total of 125 disabled soldiers with lower limb disabilities were recruited for the study. Flexibility of the lower back and hamstring muscles of uninjured lower limb was measured using back saver sit and reach test described by Wells and Dillon (1952). Upper limb and shoulder girdle flexibility was assessed using shoulder stretch test. Score 0-3 was given according to the ability to reach Superior medial angle of the opposite scapula, top of the head or the mouth. The results indicate that 31 (24.8%) disabled soldiers have lower limb flexibility less than 8, 2 (1.6 % ) have flexibility of 8, 2 (1.6 %) have flexibility of 8.5, 11 ( 8.8% ) have flexibility of 9, 14 (11.2 %) have flexibility of 9.5, 23 (18.4 %) have flexibility of 10, 17 (13.6 %) have 10.5 flexibility, 13 (10.4%) have 11 flexibility, 2 (1.6%) have 11.5 flexibility, 10 (8 %) have flexibility of 12 and 3 (2.34 %) have flexibility of 12.5. Six disabled soldiers (4.8%) have upper limb flexibility of 2 and remaining 95.2% have normal upper limb flexibility (score 3). A reduction in the flexibility of muscles in lower body and lower limbs was seen in 25% disabled soldiers which could be due to reduction in their daily physical activities. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=disability" title="disability">disability</a>, <a href="https://publications.waset.org/abstracts/search?q=flexibility" title=" flexibility"> flexibility</a>, <a href="https://publications.waset.org/abstracts/search?q=rehabilitation" title=" rehabilitation"> rehabilitation</a>, <a href="https://publications.waset.org/abstracts/search?q=quality%20of%20life" title=" quality of life"> quality of life</a> </p> <a href="https://publications.waset.org/abstracts/14964/assessment-of-hamstring-lower-back-and-upper-body-flexibility-in-war-disabled-individuals-in-sri-lanka-north-and-east-region" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/14964.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">473</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">1195</span> First Order Moment Bounds on DMRL and IMRL Classes of Life Distributions</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Debasis%20Sengupta">Debasis Sengupta</a>, <a href="https://publications.waset.org/abstracts/search?q=Sudipta%20Das"> Sudipta Das</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The class of life distributions with decreasing mean residual life (DMRL) is well known in the field of reliability modeling. It contains the IFR class of distributions and is contained in the NBUE class of distributions. While upper and lower bounds of the reliability distribution function of aging classes such as IFR, IFRA, NBU, NBUE, and HNBUE have discussed in the literature for a long time, there is no analogous result available for the DMRL class. We obtain the upper and lower bounds for the reliability function of the DMRL class in terms of first order finite moment. The lower bound is obtained by showing that for any fixed time, the minimization of the reliability function over the class of all DMRL distributions with a fixed mean is equivalent to its minimization over a smaller class of distribution with a special form. Optimization over this restricted set can be made algebraically. Likewise, the maximization of the reliability function over the class of all DMRL distributions with a fixed mean turns out to be a parametric optimization problem over the class of DMRL distributions of a special form. The constructive proofs also establish that both the upper and lower bounds are sharp. Further, the DMRL upper bound coincides with the HNBUE upper bound and the lower bound coincides with the IFR lower bound. We also prove that a pair of sharp upper and lower bounds for the reliability function when the distribution is increasing mean residual life (IMRL) with a fixed mean. This result is proved in a similar way. These inequalities fill a long-standing void in the literature of the life distribution modeling. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=DMRL" title="DMRL">DMRL</a>, <a href="https://publications.waset.org/abstracts/search?q=IMRL" title=" IMRL"> IMRL</a>, <a href="https://publications.waset.org/abstracts/search?q=reliability%20bounds" title=" reliability bounds"> reliability bounds</a>, <a href="https://publications.waset.org/abstracts/search?q=hazard%20functions" title=" hazard functions"> hazard functions</a> </p> <a href="https://publications.waset.org/abstracts/47988/first-order-moment-bounds-on-dmrl-and-imrl-classes-of-life-distributions" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/47988.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">397</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">1194</span> Mineral Chemistry of Barium and Titanium-Bearing Biotite in Alkaline Trachyte from Upper Benue Valley (Northern Cameroon)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fadimatou%20Ngounouno%20Yamgouota">Fadimatou Ngounouno Yamgouota</a>, <a href="https://publications.waset.org/abstracts/search?q=Isaac%20Bertrand%20Gbambi%C3%A9%20Mbowoub"> Isaac Bertrand Gbambié Mbowoub</a>, <a href="https://publications.waset.org/abstracts/search?q=Ismaila%20Ngounounob"> Ismaila Ngounounob</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Barium and titanium bearing biotite from alkaline trachyte of Upper Benue valley, Northern Cameroon is studied. The iron enrichment index of mica (average I.E.=0.40) is intermediate between annite and phlogopite. The biotite phenocrysts contain up to 6.2 wt. % BaO and 9.8 wt. % TiO2. The BaO content of electron-microprobe mica is positively correlated with the Al2O3, TiO2, and FeO contents, and negatively correlated with the SiO2, K2O, and MgO contents. Ba and Ti rich micas are generally found in in SiO2 deficient rocks, whereas Ba and Ti bearing mica in this study occur in silica-saturated rocks. Most of the phenocrysts analysed have deficiencies in their octahedral and interlayer sites. Deficiencies in the octahedral sites may arise from the Ti vacancy and partly the Ti tschermakite substitution. On the other hand, deficiencies in the interlayer-site are due to the replacement of K by Ba. The substitution mechanism in the Upper Benue valley mica is characterized by Ba + 2Ti + 3Al =(K + Na + Ca) + 3(Mg + Fe + Mn) + 3Si, with an excellent correlation coefficient. Biotite compositions from the Upper Benue valley area fall between the quartz-fayalite-magnetite (QFM) and nickel-nickel-oxide (NNO) oxygen fugacity buffers. All these show that Upper Benue valley mica with high Ba and Ti contents may be formed from magmas rich in these elements. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Benue%20valley" title="Benue valley">Benue valley</a>, <a href="https://publications.waset.org/abstracts/search?q=trachyte" title=" trachyte"> trachyte</a>, <a href="https://publications.waset.org/abstracts/search?q=biotite" title=" biotite"> biotite</a>, <a href="https://publications.waset.org/abstracts/search?q=mineral%20chemistry" title=" mineral chemistry"> mineral chemistry</a>, <a href="https://publications.waset.org/abstracts/search?q=enrichment" title=" enrichment"> enrichment</a> </p> <a href="https://publications.waset.org/abstracts/6752/mineral-chemistry-of-barium-and-titanium-bearing-biotite-in-alkaline-trachyte-from-upper-benue-valley-northern-cameroon" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/6752.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">297</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1193</span> Body Perception and Self-Esteem in Individuals Performing Bodybuilding Exercise Program</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yildiz%20Erdoganoglu">Yildiz Erdoganoglu</a>, <a href="https://publications.waset.org/abstracts/search?q=Unzile%20Tunc"> Unzile Tunc</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The aim of this study was to determine the relationship of body, upper extremity, lower extremity endurance, and core functionality with body perception and self-esteem in individuals who applied for a bodybuilding exercise program. Forty volunteer male subjects who underwent bodybuilding exercises for one year or more were included in the study. After obtaining demographic information of the individuals, trunk endurance was evaluated by curl-up and modified Sorensen test, upper extremity endurance by push-up test, lower extremity endurance by repeated squat test, core functionalities by single-leg wall sitting and repeated single-leg squatting tests. body perception, body image perception scale, and self-esteem were evaluated with Rosenberg self-esteem scale. The mean age of the individuals was 25.60 ± 4.70 years, mean exercise time was 22.47 ± 34.60 months. At the end of the study, body perception was low, and self-esteem was moderate. There was no significant relationship between abdominal endurance, back extensor endurance, upper extremity, and lower extremity endurance, core functionality, and body perception (p > 0.05). Also, there was no significant relationship between abdominal extensor, back extensor, upper extremity and lower extremity endurance, core functionality, and self-esteem (p > 0.05). The body, upper and lower extremity endurance, and core functionality of bodybuilders did not have any effect on body perception and self-esteem, suggesting that these individuals did not contribute positively to their efforts to improve their body perception and self- esteem. <p class="card-text"><strong>Keywords:</strong> <a
