Flexibility and curvature effects on vortex dynamics and fluid-structure interactions

Experiments were conducted to illustrate the ways in which flexibility, shape, and boundary conditions affect the vortex dynamics of the flow past a cylinder, particularly in the Reynolds number regime that characterizes biological and environmental flows. First, the flow past a freely-vibrating, flexible cantilevered cylinder is found to exhibit discontinuous regions of vortex-induced vibrations, called “states,” as a function of the reduced velocity U∗. These states are demarcated by discrete changes in the dominant eigenmodes of the structural response as the cylinder vibrates in progressively higher structural modes with increasing U∗. The wake response between different states is also found to have distinct characteristics; of particular note is the occurrence of a P+S wake over one of these regions, which is associated with the constructive interference of contributing eigenmodes. Second, a rigid, curved cylinder aligned with the flow direction with a concave orientation is found to exhibit regions of non-shedding separated flow as a consequence of the axial flow induced by curvature and also by the free end. The wake characteristics depend on the curvature, aspect ratio, and Reynolds number. Increasing curvature or decreasing aspect ratio mitigates vortex shedding. The vortex shedding in the laminar regime depends only on the local inclination of the cylinder along the span, though this result does not apply in the transitional regime. The wake transition is linked to a concurrent change in the Strouhal number and the shedding angle. Lastly, the no-slip boundary condition on a straight, normal cylinder is replaced with a liquid-infused or liquid-coated surface intended to produce a partial slip condition. The drag and Strouhal number are unaffected by the surface treatment, contrary to previous findings on superhydrophobic surfaces. A small increase in shear upstream of the separation point is noted in the time-averaged vorticity fields.
Factors associated with childhood underweight among orphaned preschool children: A community-based analytical cross-sectional study in Southern Ethiopia

Background: Childhood underweight is one of the major public health problems in Ethiopia. In Ethiopia, most of the available evidence is related to the general community children, which had different risk and severity levels than orphan children. Even though under-five orphan children have a higher risk of being underweight, they are the most neglected population. Objective: The study aims to determine the prevalence and factors associated with childhood underweight among orphaned preschool children in Southern Ethiopia. Methods: A community-based analytical cross-sectional study was conducted among 367 orphans. The burden of childhood underweight was assessed using World Health Organization standard cutoff points below −2 SD using z-scores. All variables with a p-value of < 0.25 during binary logistic regression analysis were entered into a multivariate logistic regression analysis to identify predictor variables independently associated with underweight at a p-value of 0.05 with 95% CI. Results: In this study, the prevalence of underweight among orphan children was 27.4%. The main factors associated with underweight were female child (adjusted odds ratio (aOR) = 5.29, 95% confidence interval (CI) (2.83–9.92)), adult food as type of first complementary food (aOR = 2.47; 95% CI (1.24–4.94)), food insecurity (aOR = 1.98; 95% CI (1.23–3.21)), and child age from 24–59 months (aOR = 7.19; 95% CI (3.81–13.60)). Conclusion: Childhood underweight is a public health problem in the study area. The sex of a child, type of first complementary food, household food security status, and child age were the major predictors of underweight. Therefore, appropriate dietary interventions, nutrition education, and increased food security status of orphan children are highly recommended.
CHALLENGES FACING SCHOOL BOARD OF MANAGEMENT INTHE IMPLEMENTATION OF THE PROCUREMENT POLICY IN KENYA

The main purpose of this study was to identify challenges facing the implementation of the procurement process of instructional materials in Kenyan Public Primary Schools in Wareng District, Uasin Gishu County. The study was to asses SIMSC's knowledge and skills in the procurement process and challenges that hinder compliance to the procurement policy in place. The study was based on the Systems theory as expressed by William and E. Thorndike (1903) which focuses on the need for a school (system) to function as a whole. A descriptive survey design was adopted; research was both quantitative and qualitative; the aspect of qualitative data was analyzed for their qualitative value; questionnaires, interviews, and document analysis were used to collect data. Research instruments were tested for validity and reliability. A sample size of 152 respondents comprising 38 head teachers, 76 panel heads, and 1 DQASO were drawn from 38 public primary schools to participate in the study through quarter, purposive and stratified simple random sampling techniques. Data was analyzed using qualitative descriptive statistical technique, specifically frequencies and percentages. A bar graph, pie charts, and tables were used to present data. The study revealed that, inadequate, late disbursement of funds, SIMSC's lack of knowledge and skills in the procurement process, and un- procedural procurement practices adopted by schools compromised the implementation of the procurement process. Finally, the study established that, the level of compliance to the procurement process is still low and majority of schools still flawed procurement rules. The study recommends that the process and policies be simplified and proper monitoring and evaluation strategies on procurement be put in place.
Study of extrapulmonary tuberculosis in tertiary care hospital children with reference to cartridge based nucleic acid amplification test

Background: Tuberculosis is an infectious disease cause by the mycobacterium tuberculosis which typically involve lung but can affect other site called extrapulmonary tuberculosis (EPTB). In EPTB lymph node tuberculosis is most common and most severe is tuberculous meningitis. Cartridge based nucleic acid amplification test (CBNAAT) have high sensitivity and perform both respiratory and non-respiratory specimen. The aim of this retrospective study is to find out the proportion of extra pulmonary tuberculosis in hospitalized patient and determine the association of CBNAAT in diagnosis EPTB and Rifampicin resistance.Methods: This is the retrospective observational study done at Civil Hospital Ahmedabad in between October 2017 to October 2019 among the admitted patient age 1 month to 12 year diagnosed cases of EPTB according to RNTCP guidelines. Data collection done by medical records as indoor case sheets and investigation data from laboratory department.Results: Incidence of EPTB among the hospitalized children is 1.95% and among total tuberculosis patient is 42.48%. Among 191 suspected EPTB cases 59 confirmed indicate sensitivity of 37.3% and no false positive cases indicate 100% positive predictive value. Sensitivity of CBNAAT was highest in gastric aspirate followed by CSF in present study.Conclusions: Tuberculosis is more common in male child less than 5-year-old with frequent risk factor is rural residential area, lower socioeconomic class and contact with active cases. In my study is CNS tuberculosis is most common. In my study mortality is higher among 1-to-5-year age group with co morbid condition are SAM and septicemia.
EFFECT OF EDUCATIONAL LEVEL ON ATTITUDE TOWARDS THE PHYSICALLY CHALLENGED PERSONS IN KOGI STATE, NIGERIA

People living with physical challenges constitutes part of the larger society and should be given the inclusive opportunity to engage fully in societal activities. The plight of persons with disabilities in Kogi State, Nigeria, has attracted increasing concern over the years. Thus, the present study aimed to examine the variations in attitude towards the person with physical challenges in Kogi State based on educational level. The study adopted a cross-sectional research design. One hundred and seventeen (n=117) participants randomly pooled from different locations in the Kogi State, Nigeria, participated in the study. The participants completed a self-report measure of the modified version of the Attitudes towards Disabled Persons (SADP) Scale. The result revealed that the participants primarily showed positive attitudes towards persons with physical challenges despite their educational level. Also, the result of the simple linear regression conducted to test the hypothesis revealed that educational level does not predict attitude towards the physically challenged.
Revising the Civil Engineering Curriculum at The University of Sydney

A major revision of the civil engineering curriculum took place in 2004/2005. The reasons for the revision included: rationalisation of course offerings, changes in expectations from industry and the institutions, simpler integration with combined degrees offered by the faculty, moves toward a common engineering first year, reductions in staff numbers, changing student expectations and abilities, and greater integration of teamwork and generic skills development within the course. The review process involved a SWOT analysis of the undergraduate programme/department , surveys of alumni who have graduated since the last major course change in 1995, surveys of employers of engineering graduates, focus groups with current students, and input from the Department's industry advisory group. The paper will discuss some of the results of these surveys. It was found that the combination of a desire to take a gradual approach to change and the constraints provided by faculty and various combined degrees meant that there was little flexibility for innovation in curricula. However, the broad thrust of the changes were consistent with the objectives set out by the ASCE in their body of knowledge for the 21st century, and with statements by EUCEET in Europe. The paper will discuss the constraints and compare the adopted course outline with curricula in other parts of the world. Although one of the primary intentions of the course changes was to better integrate the various branches of civil engineering (structures, geotechnical, fluids, and project management) this was found to be difficult to achieve while allowing students the flexibility to take courses outside the core. There was considerable debate on the core curriculum and the value of professional engineering subjects within this core. The paper will discuss these issues and the compromises that were agreed. A further important consideration was the role of The University of Sydney as a research intensive organisation, and the desire to produce students with the skills and motivation to follow more academically focused careers.
At War’s End: Building Peace After Civil Conflict

of distinguished and rather senior economists – makes at the end of the book. Their priorities tend to be quick-fixes of problems that might, at least partly, be caused by some other challenge. More importantly, the panellists tend to disregard some of the evidence assembled by the authors. The reactions to the excellent chapter on armed conflict by Collier & Hoeffler illustrate that Nobel awards are no protection against bias. One member of the panel dismisses the economic sources of war that the Oxford economists analyse and points out that free trade is the main pacifying force, while another famous panellist mentions ethnic or religious hatred as a source of conflict.

Disposal of donor livers in Brazil: how to optimize their utilization rate in transplants?

ABSTRACT Objective: To understand the professionals´ perception of the use of deceased donor liver for transplantation, the reasons to decline them, and propose strategies to increase their use safely. Methods: This is a cross-sectional, descriptive qualitative-quantitative study. Professionals working with liver transplantation answered a self-administered, structured, and electronic questionnaire comprising 17 questions distributed into four sessions (demographic factors, perception of use of organs, reasons for disposal, and measures to favor their usage). Results: A total of 42 professionals participated in the study. The rate of use of organs was considered low by 71.43% (n=30) of respondents or very low by 19.05% (n=8). Everyone agreed that it was possible to increase it. Thirty-one (73.81%) participants believed the expansion of the population of extended criteria donors affected this index negatively. Donor-related conditions were the most frequent category of reasons for refusing a liver for transplantation, being the findings during organ retrieval the most frequent reason in clinical practice. Enhanced training of intensive care teams in the treatment of donors was the primary measure selected to favor the use of the organs, followed by investment in new technologies to optimize its preservation/evaluate its function before transplantation. Conclusion: Implementation of strategies to increase the rate of acceptance of livers is expected. Improvements in donor intensive care and implementation of new preservation technologies should favor the use of the organs.
Barriers on ESL CALL Programs in South Texas

This paper proposes a methodology to discover the barriers that influence English as second language (ESL) teachers in the use of computers in their classrooms. The participants in the study were sixty­seven ESL teachers who applied computer assisted language learning (CALL) in the classroom or computer lab in schools in Corpus Christi Independent School District (CCISD) and Kingsville Independent School District (KISD) in South Texas. The survey study included the participants’ demographic data, twenty variables influencing the use of CALL, and five open­ended questions. The researcher designed and verified the reliability and validity of the questionnaire. The resulting survey data were then analyzed using Exploratory Factor Analysis (EFA) to capture the information in the survey and to identify a set of factors that hinder the use of CALL in ESL. The findings demonstrate that there are three key barriers that impact teachers who use CALL programs to teach ESL, and ESL teachers may change their roles as they implement CALL programs. These barriers are technology skills, funding for teaching through technology, and acceptance of technology. The results can help educators to understand better the impact of CALL and to anticipate the barriers of CALL program they may face.
Clinico-toxicological effects of ceftriaxone after intramuscular administration of graded doses in Basenji dogs

Purpose: The recent ceftriaxone-induced anaemia and mortalities at the dose of 50 mg/kg in Veterinary Teaching Hospital, University of Nigeria prompted this study which sought to assess the clinicotoxicological effects of ceftriaxone (CFZ) after intramuscular administration of graded doses in Basenji dogs.Methods: The effects of CFZ on the haematological indices, physiological parameters, liver and kidney functions were assessed in 4 group of dogs (n = 4) designated A – D. They were given CFZ intramuscularly for 21 days at doses of 12, 25 and 50 mg/kg for groups A, B, C, respectively, while thecontrol (group D) received the diluent (lignocaine 0.2 mL)Results: The mean pulse and heart rate of dogs in group C were significantly (p < 0.05) higher than those of group A, B and D. Significant (p < 0.05) decrease in red blood cell count (RBC), haemoglobin concentration (Hb) and packed cell volume (PCV) was observed in group C on days 7 and 14, while on day 21, these parameters were significantly (p < 0.05) higher in group D than in the treated groups. On day 14 of CFZ administration, the alanine transaminase (ALT), aspartate aminotransferase (AST) and alkaline phosphatase (ALP) activities of dogs in group C was significantly (p < 0.05) elevated than the control group.Conclusion: These findings suggest that CFZ, at the doses of 12.5 - 25 mg/kg, appears safe in dogs as most of the adverse effects observed are reversed following the withdrawal of the drug on day 28. However, CFZ at 50 mg/kg causes anaemia, tachycardia and bilateral paralysis of the hind limbs which did not revert to normal after one week; hence, it is not recommended for use in dogs at this dose.
Using Statistical Regression Analysis to Establish Construction Cost Models for Seismic Retrofit of Confined Masonry Buildings

AbstractThe presented research deals with the development of statistical models for predicting seismic retrofit net construction cost (RNCC) of confined masonry (CM) buildings. Real data from 183 CM school buildings in Iran were collected to establish the RNCC and its determinant variables, among which two were unprecedented in the literature: (1) mortar quality, and (2) the concrete quality of confinement elements. Parametric models were developed using the stepwise regression technique, and the leave-one-out cross-validation technique was utilized to examine the predictive performance of these models. Four variables were selected that collectively best predicted the RNCC variation: (1) total floor area, (2) seismic weight indicator, (3) floor and roof diaphragm type, and (4) mortar quality. On the basis of this selection, similarities and discrepancies between the RNCC prediction of framed and CM structures were described, with dissimilarities being postulated to arise from different seismic evaluation .
A Structural Framework to Assess the Influence of CSFS on Risk Management Case Study: Oil and Gas Sector in Iran

With regard to changing business environment over the last two decades, risk management has become a main area of business practice to define, analyse and control uncertainties. It necessitates identifying critical areas of planning and actions which must be considered to achieve effectiveness named Critical Success Factors (CSFs). The aim of this study is to classify and prioritize the CSFs necessary for risk management in oil and gas sector in Iran. In order to do the research a comprehensive set of CSFs were selected in the existing streams of research. Accordingly ten CSFs were identified named commitment and support, communication, culture, structure, IT, process management, resources, training, strategy and measurement. The quantitative method was employed in data collection by using questionnaire. Then to evaluate the influence of each CSF on risk management, an empirical study was conducted by Principal Components Analysis (PCA) by using SPSS package to classify CSFs and extract main factors. The CSFs are categorized into three components; management, operation and context. Then, the extent to which each CSF impacts on risk was measured through a structural model by using Confirmatory Factor Analysis (CFA) by applying Smart PLS package. Consequently, the obtained results indicated that two components; management and context had eigen value greater than one, acceptable reliability (Cronbach's alpha and Dillion- Goldstein's ρ (D.G.'s ρ) >0.7) and validity (AVE>0.5). Furthermore, this framework showed a satisfactory fitness (GoF = 0.76). This study provides with top managers key insight into the CSFs influencing risk management to proper resource allocation.
Mantle Cell Lymphoma: Updates in the Management of Relapsed/Refractory Disease

Mantle cell lymphoma remains incurable despite recent treatment advances, and most patients experience relapsed/refractory disease. BTK inhibitors are the preferred choice in the relapsed setting, especially in patients with early relapse. For patients with high-risk features such as TP53 mutation, early referral for CAR T-cell therapy should be considered, even in those with stable disease on a BTK inhibitor. Patients without high-risk features may be monitored and initiate CAR T-cell therapy after clinical disease progression. CAR T-cell therapy is an effective treatment with high rate of complete remissions. For patients who do not achieve a complete remission 3 months after CAR-T therapy, bridging therapy with chemotherapy or targeted therapy agents and referral for allogeneic transplant are recommended.
Chemical Composition of White Wines Produced from Different Grape Varieties and Wine Regions in Slovakia

In this work, chemical parameters such as sugar (glucose and fructose) content, organic acid (total acids, malic and tartaric acids), total phenolic content and the antioxidant activity of 12 white wines (chardonnay, pinot blanc and pinot gris) from various wine regions in Slovakia were studied in order to identify differences among the varieties and wine-growing regions. The wine samples were examined by Fourier-transform infrared spectroscopy (FTIR) and UV-VIS spectrophotometry (for determination of total polyphenolic content (TPC) and total antioxidant activity (TAA)) methods. Content of alcohol ranged between 11.50% and 13.80% with the mean value 12.52%. Mean content of total acids varied between 4.63 ± 0.09 and 6.63 ± 0.05 g.L−1, tartaric acid varied between 1.62 ± 0.09 and 2.93 ± 0.03 g L−1, malic acid was found in the concentrations ranged from 0.07 ± 0.05 and 2.50 ± 0.08 g L−1 and lactic acid was present between 1.53 and 0.01 g L−1. The content of fructose was, in general, higher in the samples from the Južnoslovenská and Nitrianska wine regions and glucose was higher in the Malokarpatská wine region. Chardonnay wines showed the highest content of total polyphenols and the antioxidant activity in the samples ranged from 51.06 ± 027 to 72.53 ± 0.35% inhibition of DPPH. The PCA analysis based on chemical descriptors distinguished the Nitrianska and Stredoslovenská wine regions. According to similarities among the wine samples, four main classes were formed by cluster analysis.
Modelling abrupt changes: enhanced learning of behaviour models for manufacturing systems

Modern manufacturing systems are complex technical systems that exhibit state-based, continuous, timed, and probabilistic behaviour. Modelling such systems is becoming increasingly hard, and yet their behaviour models are today mostly created manually. This paper gives an asset to learning these models automatically from data The HyBUTLA algorithm for learning the hybrid automata models, which can represent manufacturing system’s characteristics, has been recently proposed. However, it could not model the abrupt changes in the continuous part of the system. The contribution of this paper is as follows: the split function that detects and models abrupt changes is presented; both sufficient and necessary conditions for its success are formally proven; the complete HyBUTLA algorithm enhanced with the split function is given; experimental results conducted in a real manufacturing system are presented.
