2. Solving the Boundary Layer Flow of an Eyring-Powell Non-Newtonian Fluid

Author

Abstract

In this paper, the Rational Jacobi (RJ) collocation method is proposed to approximate the solution of the boundary layer flow of an Eyring-Powell fluid over a stretching sheet. This equation is nonlinear and by applying Quasilinearization method (QLM), the equation is converted into a sequence of linear ordinary differential equations (ODE) converging to the solution of the nonlinear equation. Unlike other methods, instead of truncation in domain, the infinity condition is satisfied implicitly. As a result, using the proposed method, the model is converted to a system of linear algebraic equations. The effect of different parameters on the velocity profile is also presented., Comment: 20 pages, 14 figure

Abstract

Treatments that stimulate neuronal excitability enhance motor performance after stroke. cAMP-response-element binding protein (CREB) is a transcription factor that plays a key role in neuronal excitability. Increasing the levels of CREB with a viral vector in a small pool of motor neurons enhances motor recovery after stroke, while blocking CREB signaling prevents stroke recovery. Silencing CREB-transfected neurons in the peri-infarct region with the hM4Di-DREADD blocks motor recovery. Reversing this inhibition allows recovery to continue, demonstrating that by manipulating the activity of CREB-transfected neurons it is possible to turn off and on stroke recovery. CREB transfection enhances remapping of injured somatosensory and motor circuits, and induces the formation of new connections within these circuits. CREB is a central molecular node in the circuit responses after stroke that lead to recovery from motor deficits.

Abstract

BACKGROUND: Recent evidence has shown a positive correlation between obesity and viral infections with a particular emphasis on the human adenovirus-36 (Ad-36). Ad-36 is the first human virus that may increase adiposity in animals, and it is considered as a possible risk factor for obesity in humans; however, the results werenot consistentacross allthe studies. The present study was conducted to examine the influence of Ad-36 infection on obesity in a rat model. METHODS: Eight-week-old male Wistar rats weighing 170-240 gram (g), were randomly divided into two groups, infection group (48 rats) and a control group (12 rats). The rats in the infection group were infected with human Ad-36. All rats were given free access to a normal chow diet and water. They were weighed weekly. RESULTS: The mean ± standard deviation (SD) body weights were 229.0 ± 25.9 g and 232.3 ± 16.6 g in the infection and control groups, respectively at the time of infection. The mean ± SD body weight of the infection group (304.0 ± 39.0 g) was higher than the control group (301.0 ± 36.5 g) at 12 weeks post-infection (P = 0.82). Although two groups had approximately same food intakes, the mean change in body weight was greater in the infection group than the control group (75.8 ± 27.9 g vs. 70.8 ± 24.5 g) but it was not significant (P = 0.57). CONCLUSION:We did not find a statistically significant association between weight gain and Ad-36 infection in the rat model. It seems that longer follow-up duration is needed to develop a significant weight gain in the infected rats. Rats can be used as a good animal model for further investigations about Ad-36-induced obesity, provided not to rely merely on weight measurements. Evaluating body composition or histopathological assessments are suggested.&nbsp

Abstract

Copyright © 2016 by the Society of Critical Care Medicine and the World Federation of Pediatric Intensive and Critical Care Societies.Objectives: To describe the epidemiology, morbidity, and mortality of new or progressive multiple organ dysfunction syndrome in children with severe sepsis. Design: Secondary analysis of a prospective, cross-sectional, point prevalence study. Setting: International, multicenter PICUs. Patients: Pediatric patients with severe sepsis identified on five separate days over a 1-year period. Interventions: None. Measurements and Main Results: Of 567 patients from 128 PICUs in 26 countries enrolled, 384 (68%) developed multiple organ dysfunction syndrome within 7 days of severe sepsis recognition. Three hundred twenty-seven had multiple organ dysfunction syndrome on the day of sepsis recognition. Ninety-one of these patients developed progressive multiple organ dysfunction syndrome, whereas an additional 57 patients subsequently developed new multiple organ dysfunction syndrome, yielding a total proportion with severe sepsis-associated new or progressive multiple organ dysfunction syndrome of 26%. Hospital mortality in patients with progressive multiple organ dysfunction syndrome was 51% compared with patients with new multiple organ dysfunction syndrome (28%) and those with single-organ dysfunction without multiple organ dysfunction syndrome (10%) (p < 0.001). Survivors of new or progressive multiple organ dysfunction syndrome also had a higher frequency of moderate to severe disability defined as a Pediatric Overall Performance Category score of greater than or equal to 3 and an increase of greater than or equal to 1 from baseline: 22% versus 29% versus 11% for progressive, new, and no multiple organ dysfunction syndrome, respectively (p < 0.001). Conclusions: Development of new or progressive multiple organ dysfunction syndrome is common (26%) in severe sepsis and is associated with a higher risk of morbidity and mortality than severe sepsis without new or progressive multiple organ dysfunction syndrome. Our data support the use of new or progressive multiple organ dysfunction syndrome as an important outcome in trials of pediatric severe sepsis although efforts are needed to validate whether reducing new or progressive multiple organ dysfunction syndrome leads to improvements in more definitive morbidity and mortality endpoints.

Abstract

Methods are presented to embed Hamiltonian paths (H-paths) and Hamiltonian cycles (H-cycles) in a star graph [S.sub.n] in a faulty environment. The models considered include single-processor failure, double-process failure, and multiple-processor failures. All three models are applied to an H-path/cycle, which is formed by visiting all the (n!/4!) [S.sub.4]s in an [S.sub.n] in a particular order. An optimal embedding is obtained in the case of single-processor failure, wherein the length of the H-path/cycle is shown to be (n! - 2). The multiple-processor failure model is developed based on single and double processor failure models. In this case the length of the H-cycle that can be embedded is shown to be (n! - 2f), where f [less than or equal to] n - 2 is the number of faults. Another case of multiple-failure scenario is investigated by assuming that all faults are contained in a single [S.sub.m], m [less than] n. The network in this case, is shown to reduce to a cluster-star graph. It is proven that it is always possible to formulate an H-cycle of length (n! - m!) in such a network. Key words: Embedding, fault-tolerance, Hamiltonian, permutation, star graph.

Abstract

The problem of embedding link-disjoint Hamiltonian cycles into torus networks is addressed. The maximum number of link-disjoint cycles is limited to half the degree of the node in a regular network. Simple methods are presented to embed the maximum number of link-disjoint Hamiltonian cycles in an r-dimensional torus network. An algorithm for finding a Hamiltonian cycle in an r-dimensional torus in the presence of a set of faulty links is also given. Key words: Fault-tolerant computing, network embedding, parallel and distributed computing, ring.

Abstract

Ca ion release from bioactive biomaterials could play an important role in their bioactivity and osteoconductivity properties. In order to improve hydroxyapatite (HA) dissolution rate, in situ apatite-silica nanocomposite powders with various silica contents were synthesized via sol-gel method and mechanisms controlling the Ca ion release from them were investigated. Obtained powders were characterized by X-ray diffraction (XRD) and transmission electron spectroscopy (TEM) techniques, acid dissolution test, and spectroscopy by atomic absorption spectrometer (AAS). Results indicated the possible incorporation of (SiO4)4- into the HA structure and tendency of amorphous silica to cover the surface of HA particles. However, 20 wt. % silica was the lowest amount that fully covered HA particles. All of the nanocomposite powders showed more Ca ion release compared with pure HA, and HA - 10 wt. % silica had the highest Ca ion release. The crystallinity, the crystallite size, and the content of HA, along with the integrity, thickness, and ion diffusion possibility through the amorphous silica layer on the surface of HA, were factors that varied due to changes in the silica content and were affected the Ca ion release from nanocomposite powders.

Abstract

BACKGROUND AND OBJECTIVE: Premature ovarian failure, with a prevalence of 1% in women under the age of 40, leads to serious health problems for women of childbearing age. Since the causes are not fully understood and the available treatments are associated with side effects, complementary medicine, including Persian medicine, can be helpful. The aim of this study was to report a case of pregnancy following successful treatment of premature ovarian failure. CASE REPORT: The patient was a 38-year-old woman with a history of 16 months of amenorrhea who had atrophic ovaries on ultrasound. Due to increased gonadotropins, decreased estradiol and anti-mullerian hormone, the gynecologist diagnosed premature ovarian failure. After referring to the Persian Medicine Clinic and after getting a history and examination, her treatment started which included lifestyle modification and medication (2 Raha capsules every 12 hours, 2 tablespoons of Sekanjabin-e-Bazoori [oxymel] a day, decoction of Chamomile and Pennyroyal 200 cc per day and Abzan [a human-sized container filled with hot water] with four plants of Hollyhocks, Chamomile, Rose, and Mallow twice a week). The patient was followed for 18 months. Menstruation occurred after 3 months and the ovaries were normal size after 8 months on the second ultrasound and 10 months after starting treatment, the patient became pregnant and the result was a healthy male baby. CONCLUSION: According to the results of the present study, Persian medicine can be effective in treating infertility caused by premature ovarian failure. [ABSTRACT FROM AUTHOR]

Abstract

Copyright © 2016 by the Society of Critical Care Medicine and the World Federation of Pediatric Intensive and Critical Care Societies.Objectives: Pediatric severe sepsis remains a significant global health problem without new therapies despite many multicenter clinical trials. We compared children managed with severe sepsis in European and U.S. PICUs to identify geographic variation, which may improve the design of future international studies. Design: We conducted a secondary analysis of the Sepsis PRevalence, OUtcomes, and Therapies study. Data about PICU characteristics, patient demographics, therapies, and outcomes were compared. Multivariable regression models were used to determine adjusted differences in morbidity and mortality. Setting: European and U.S. PICUs. Patients: Children with severe sepsis managed in European and U.S. PICUs enrolled in the Sepsis PRevalence, OUtcomes, and Therapies study. Interventions: None. Measurements and Main Results: European PICUs had fewer beds (median, 11 vs 24; p < 0.001). European patients were younger (median, 1 vs 6 yr; p < 0.001), had higher severity of illness (median Pediatric Index of Mortality-3, 5.0 vs 3.8; p = 0.02), and were more often admitted from the ward (37% vs 24%). Invasive mechanical ventilation, central venous access, and vasoactive infusions were used more frequently in European patients (85% vs 68%, p = 0.002; 91% vs 82%, p = 0.05; and 71% vs 50%; p < 0.001, respectively). Raw morbidity and mortality outcomes were worse for European compared with U.S. patients, but after adjusting for patient characteristics, there were no significant differences in mortality, multiple organ dysfunction, disability at discharge, length of stay, or ventilator/vasoactive-free days. Conclusions: Children with severe sepsis admitted to European PICUs have higher severity of illness, are more likely to be admitted from hospital wards, and receive more intensive care therapies than in the United States. The lack of significant differences in morbidity and mortality after adjusting for patient characteristics suggests that the approach to care between regions, perhaps related to PICU bed availability, needs to be considered in the design of future international clinical trials in pediatric severe sepsis.

Abstract

Over time Business Process has become an asset for organization since it allows managing what happens within their environments. It is possible to automate some activities of the business process using information systems and accordingly decrease the execution time and increase the production. How- ever, information systems often suffer maintenance over time and become obsolete and a re-engineering process is necessary. In this case, the business knowledge, located more accurately the reality in source code, should be maintained. Thereof, this paper propose an approach to support the business process recovery from source code. For this purpose, the approach uses KDM standard with a set of heuristic rules to identify relevant code elements to the business layer. As result, the models are generated according to the BPMN specification that, together with other artifacts, provide more subsidies to the professionals involved. To evaluate the effectiveness of the approach, a case study was performed in an Academic Management System.

Abstract

Scorpion envenomation is an important health problem in south-west of Iran. The present research study was conducted to find new information due to scorpionism in Dezful region in the south of Khuzestan province from point of entomo-climatology and correlations of climatology variables with the scorpion sting incidence in the area to predict the scorpion sting incidence. This research was a descriptive and analytic retrospective study. The correlation rates between the climatology data and incidence of scorpion stings were observed significant in all of monitored environmental factors. From the data of the present study it is concluded that the scorpion activity is an environmental climatology dependent specially temperature with dominant effects in the environment.

Abstract

Objectives: The prevalence of septic acute kidney injury and impact on functional status of PICU survivors are unknown. We used data from an international prospective severe sepsis study to elucidate functional outcomes of children suffering septic acute kidney injury. Design: Secondary analysis of patients in the Sepsis PRevalence, OUtcomes, and Therapies point prevalence study: acute kidney injury was defined on the study day using Kidney Disease Improving Global Outcomes definitions. Patients with no acute kidney injury or stage 1 acute kidney injury ("no/mild acute kidney injury") were compared with those with stage 2 or 3 acute kidney injury ("severe acute kidney injury"). The primary outcome was a composite of death or new moderate disability at discharge defined as a Pediatric Overall Performance Category score of 3 or higher and increased by 1 from baseline. Setting: One hundred twenty-eight PICUs in 26 countries. Patients: Children with severe sepsis in the Sepsis PRevalence, OUtcomes, and Therapies study. Interventions: None. Measurements and Main Results: One hundred two (21%) of 493 patients had severe acute kidney injury. More than twice as many patients with severe acute kidney injury died or developed new moderate disability compared with those with no/mild acute kidney injury (64% vs 30%; p < 0.001). Severe acute kidney injury was independently associated with death or new moderate disability (adjusted odds ratio, 2.5; 95% CI, 1.5-4.2; p = 0.001) after adjustment for age, region, baseline disability, malignancy, invasive mechanical ventilation, albumin administration, and the pediatric logistic organ dysfunction score. Conclusions: In a multinational cohort of critically ill children with severe sepsis and high mortality rates, septic acute kidney injury is independently associated with further increased death or new disability.

Abstract

Objectives: Pediatric severe sepsis remains a significant global health problem without new therapies despite many multicenter clinical trials. We compared children managed with severe sepsis in European and U.S. PICUs to identify geographic variation, which may improve the design of future international studies. Design: We conducted a secondary analysis of the Sepsis PRevalence, OUtcomes, and Therapies study. Data about PICU characteristics, patient demographics, therapies, and outcomes were compared. Multivariable regression models were used to determine adjusted differences in morbidity and mortality. Setting: European and U.S. PICUs. Patients: Children with severe sepsis managed in European and U.S. PICUs enrolled in the Sepsis PRevalence, OUtcomes, and Therapies study. Interventions: None. Measurements and Main Results: European PICUs had fewer beds (median, 11 vs 24; p < 0.001). European patients were younger (median, 1 vs 6 yr; p < 0.001), had higher severity of illness (median Pediatric Index of Mortality-3, 5.0 vs 3.8; p = 0.02), and were more often admitted from the ward (37% vs 24%). Invasive mechanical ventilation, central venous access, and vasoactive infusions were used more frequently in European patients (85% vs 68%, p = 0.002; 91% vs 82%, p = 0.05; and 71% vs 50%; p < 0.001, respectively). Raw morbidity and mortality outcomes were worse for European compared with U.S. patients, but after adjusting for patient characteristics, there were no significant differences in mortality, multiple organ dysfunction, disability at discharge, length of stay, or ventilator/vasoactive-free days. Conclusions: Children with severe sepsis admitted to European PICUs have higher severity of illness, are more likely to be admitted from hospital wards, and receive more intensive care therapies than in the United States. The lack of significant differences in morbidity and mortality after

Abstract

Introduction: Consensus criteria for pediatric severe sepsis have standardized enrollment for research studies. However, the extent to which critically ill children identified by consensus criteria reflect physician diagnosis of severe sepsis, which underlies external validity for pediatric sepsis research, is not known. We sought to determine the agreement between physician diagnosis and consensus criteria to identify pediatric patients with severe sepsis across a network of international pediatric intensive care units (PICUs). Methods: We conducted a point prevalence study involving 128 PICUs in 26 countries across 6 continents. Over the course of 5 study days, 6925 PICU patients <18 years of age were screened, and 706 with severe sepsis defined either by physician diagnosis or on the basis of 2005 International Pediatric Sepsis Consensus Conference consensus criteria were enrolled. The primary endpoint was agreement of pediatric severe sepsis between physician diagnosis and consensus criteria as measured using Cohen's ?. Secondary endpoints included characteristics and clinical outcomes for patients identified using physician diagnosis versus consensus criteria. Results: Of the 706 patients, 301 (42.6 %) met both definitions. The inter-rater agreement (? ± SE) between physician diagnosis and consensus criteria was 0.57 ± 0.02. Of the 438 patients with a physician's diagnosis of severe sepsis, only 69 % (301 of 438) would have been eligible to participate in a clinical trial of pediatric severe sepsis that enrolled patients based on consensus criteria. Patients with physician-diagnosed severe sepsis who did not meet consensus criteria were younger and had lower severity of illness and lower PICU mortality than those meeting consensus criteria or both definitions. After controlling for age, severity of illness, number of comorbid conditions, and treatment in developed versus resource-limited regions, patients identified with severe sepsis by physician diagnosis

Abstract

Changes in the business environment accelerated dramatically over the last decades, due to technological innovation, regulation, market changes and competitor behavior, and has led to changes in the way firms do business. So business model innovation (BMI) plays a critical role in the success of today's firms. Companies realize that it is not an easy task to innovate a BM and many attempts fail to deliver expected outcomes. In this study, we conduct a systematic literature review to find the barriers to capture value from BMI. Based on in-depth analysis of 21 articles, we found 75 barriers to BMI that can be categorized as Strategy-related, BM design issues, BM Implementation and BM management issues. This paper offers the grounding for empirical research as well contribute to the development of tools to overcome BMI management problems, as well provide guidelines and best practices of how to implement BM Innovations.

Abstract

A twenty-year-old girl was referred with tracheal stenosis (TS) which was a consequence of prolonged intubation after head injury because of previous car accident. The patient was aphasic and had normal respiration. Fiberoptic bronchoscopy showed complete tracheal obstruction at second tracheal ring level. Distal trachea was normal through tracheostomy tube. Removal of the tracheostomy tube and blind reinsertion with a new one was complicated with hypoxia and respiratory distress. Fibrotic bronchoscopy revealed large tracheoesophageal fistula (TEF) below tracheal obstruction. Reinsertion of the tracheostomy tube by fiber optic bronchoscope was successful. Multidetector CT scan was performed on the same day with confirmation of TS combined with TEF. Surgery was performed on the next day. No clinical evidence of TEF was found in back history. Inadequate evaluation of the whole length of the trachea during the first bronchoscopy was the reasons for missing TEF. TEF should be considered in patients with TS in spite of no typical symptom such as food aspiration or pulmonary infections.

Abstract

In a user-centric service creation process, users should drive the service creation, in which services can be composed out of existing services. However, the creation is expected to take place also at runtime and possibly be performed by non-technical users. These users require support in the composition process, since they cannot deal with all the technical details of service composition. Furthermore, users have different characteristics and properties. In this paper we propose a classification of users in terms of their application domain and technical knowledge in order to identify different types of users and their requirements in the service composition process. These requirements can be used to design and build suitable supporting composition environments. Although our classification of users may seem trivial at first sight, it is quite essential for identifying users requirements and derive the appropriate supporting environment. Nowadays most of the approaches are technology-driven rather than user-oriented. We argue that only by taking the user into account a truly user-centric service creation and delivery can be achieved.

Abstract

Introduction Consensus criteria for pediatric severe sepsis have standardized enrollment for research studies. However, the extent to which critically ill children identified by consensus criteria reflect physician diagnosis of severe sepsis, which underlies external validity for pediatric sepsis research, is not known. We sought to determine the agreement between physician diagnosis and consensus criteria to identify pediatric patients with severe sepsis across a network of international pediatric intensive care units (PICUs). Methods We conducted a point prevalence study involving 128 PICUs in 26 countries across 6 continents. Over the course of 5 study days, 6925 PICU patients Results Of the 706 patients, 301 (42.6 %) met both definitions. The inter-rater agreement (κ ± SE) between physician diagnosis and consensus criteria was 0.57 ± 0.02. Of the 438 patients with a physician’s diagnosis of severe sepsis, only 69 % (301 of 438) would have been eligible to participate in a clinical trial of pediatric severe sepsis that enrolled patients based on consensus criteria. Patients with physician-diagnosed severe sepsis who did not meet consensus criteria were younger and had lower severity of illness and lower PICU mortality than those meeting consensus criteria or both definitions. After controlling for age, severity of illness, number of comorbid conditions, and treatment in developed versus resource-limited regions, patients identified with severe sepsis by physician diagnosis alone or by consensus criteria alone did not have PICU mortality significantly different from that of patients identified by both physician diagnosis and consensus criteria. Conclusions Physician diagnosis of pediatric severe sepsis achieved only moderate agreement with consensus criteria, with physicians diagnosing severe sepsis more broadly. Consequently, the results of a research study based on consensus criteria may have limited generalizability to nearly one-third of PICU patients diagnosed with severe sepsis.

The aim of this study was to compare nursing students’ clinical competence using the portfolio method with conventional education and evaluation methods in clinical education.Methods: In this pretest–posttest quasiexperimental crossover study, all six-semester undergraduate nursing students of Ahvaz Jundishapur University of Medical Sciences were classified into four groups. They were selected based on the use of portfolio and conventional methods during their apprenticeship. Then, they were educated using conventional and portfolio methods. Their clinical competence was measured by a self-appraisal questionnaire. Data were statistically analyzed with independent and paired t-tests.Results: There were significant differences between average scores of clinical competence in all three domains before and after study in portfolio-based education method (P=0.0001). Furthermore, the average difference in scores before and after internship between the two educational groups in all three domains — cognitive (P=0.002), affective (P=0.0001), and psychomotor — (P=0001) was significant. Similarly, there was a significant difference in total average scores of clinical competence between the two methods (P=0.0001).Conclusion: The results showed the effect of educational method on increasing the clinical competence of nursing students in a clinical unit. This new method can be used as a combination of education, evaluation and student-centered methods.Keywords: clinical competence, education, nursing student, portfolio

Abstract

This paper reports the results of focus groups obtained as part of a full study that uses a mixed method approach to answer the following question: what are the cultural values that impact on e-service use in Saudi Arabia? In order to answer this question we reviewed culture theories, dimensions, and models that have been identified in the literature. Four focus groups interviewing experts and general users (customers) of online services in Saudi Arabia have been completed aiming at the end to identify the uncovered elements of Saudi culture in the literature, which hopefully will result in developing a framework of cultural values that affect e-service use in Saudi context. This paper will firstly, introduce the importance of culture and define the aspects of Saudi culture. It will then describe the method used, and finally discussing the findings of the focus groups. Findings revealed four factors that have not been covered in the literature and need to be investigated namely: nepotism, the lack of human interaction, services oriented culture, and the career path.

Abstract

Having a good automatic anomalous human behaviour detection is one of the goals of smart surveillance systems’ domain of research. The automatic detection addresses several human factor issues underlying the existing surveillance systems. To create such a detection system, contextual information needs to be considered. This is because context is required in order to correctly understand human behaviour. Unfortunately, the use of contextual information is still limited in the automatic anomalous human behaviour detection approaches. This paper proposes a context space model which has two benefits: (a) It provides guidelines for the system designers to select information which can be used to describe context; (b)It enables a system to distinguish between different contexts. A comparative analysis is conducted between a context-based system which employs the proposed context space model and a system which is implemented based on one of the existing approaches. The comparison is applied on a scenario constructed using video clips from CAVIAR dataset. The results show that the context-based system outperforms the other system. This is because the context space model allows the system to considering knowledge learned from the relevant context only.

Abstract

Multi-modal biometrics has numerous advantages over unimodal biometric systems. Decision level fusion is the most popular fusion strategy in multimodal biometric systems. Recent research has shown promising performance of hand based biometrics, i.e. palmprint and hand geometry over other biometric modalities. However, the improvement in performance is constrained by the lack of optimal sensor points and fusion strategy. In this paper, we have implemented a particle swarm based optimization technique for selecting optimal parameters through decision level fusion of two modalities: palmprint and hand geometry. The experimental evaluation on a database of 100 users confirms the utility of the decision level fusion using particle swarm optimization.

Abstract

Mammography is considered as the most effective means for breast cancer diagnosis. This paper introduces two separate techniques for mass and micro-calcification segmentation in digital mammograms. Segmentation of masses consists of three steps- background subtraction, fuzzy texture representation and entropic theresholding. Similarly micro-calcifications are also segmented in three stages – background subtraction, Laplacian of Gaussian filtering and contrast estimation followed by thresholding. Both the techniques are verified with the markings given by the radiologist and are found to be quite effective tools in diagnosing breast cancer.
