Mechanics of Advanced Composite Structures

Dynamic response Curved sandwich beam Moving mass Modal analysis method In this paper, the dynamic response of a simply supported relatively thick composite sandwich curved beam under a moving mass is investigated. In contrast to previous works, the geometry of beam is considered to be in a curved form. Moreover, the rotary inertia and the transverse shear deformation are also considered in the present analysis. The governing equations of the problem are derived using Hamilton's principle. Then, the obtained partial differential equations are transformed to the ordinary differential equations with time varying coefficients, using the modal analysis method. Fourth-order Runge-Kutta method is applied to solve the ordinary differential equations in an analytical – numerical form. The obtained results are validated by the results existed in the literature. Performing a thorough parametric study, the effects of some important parameters such as the mass and the velocity of moving mass, the radius of curvature of the beam, the core thickness to the total thickness ratio and the stacking sequences of the face sheets on the dynamic response are investigated. It is observed that increasing the mass and the velocity of moving mass and the radius of curvature of beam, result in an increase, decrease and increase of the dynamic deflection of curved beam, respectively.
CORRELATION BETWEEN IPAQ AND VO2MAX AMONG OBESE WOMEN

Physical activity is widely recommended for obese and overweight individuals, due to their higher cardiovascular risk. Thus, the short form of the International Physical Activity Questionnaire (IPAQ) has been used as a good tools for evaluating and monitoring physical activity in adults. Moreover, the determination of maximum oxygen uptake (VO 2max ) has been described as one of the best methods for evaluation of physical capacity. Objective: To investigate the correlation between level of physical activity measured by IPAQ short form and VO 2max in women with overweight or obesity, and the association between body mass index (BMI) and waist circumference (WC) with the two methods. Methods: In this cross-sectional study, 48 women, aged 45.27 ± 11.56 years, 35 (72.9%) obese, answered to the IPAQ short version and underwent exercise testing to determine the maximal oxygen uptake. Results: The IPAQ continuous score was not correlated with VO 2max , nor with BMI or WC. On the other hand, it was demonstrated a significant inverse correlation between VO 2max and BMI (r = -0.50, p <0.01) and WC (r = -0.65, p <0.01). Conclusions: The IPAQ proved to be an inadequate instrument for assessing the physical performance of overweight or obese women. In contrast, the VO 2max showed a significant inverse correlation with BMI and waist circumference, reinforcing the central role of obesity as a limiting factor for aerobic performance.
Improving Performance of Laying Hens in Hot Regions by Desert Coolers

The efficacy of desert coolers to improve thermal responses and performance of laying hens under heat stress conditions was investigated. Two identical layers houses of deep litter system providing 1600 cm /hen were used. The first house was equipped with a desert cooler while the other was left without 2 control on air temperature (the control treatment). At 32 week of age, 100 hens from 2 commercial lines (Shaver and Hyline) were housed in each house. The average air temperature in the cooled house was 5.4°C lower (p<0.05) than in the control house. Drinking water temperature in the cooled house was 3.4°C lower (p<0.05) than that in the control house. Rectal temperatures of hens in the cooled house were significantly lower than that of the control. Hens housed in the cooled house showed a significan t improvement in feed conversion, significant increase in egg production, egg weight, egg mass, eggshell thickness and eggshell density and significant decrease in unmarketable eggs compared to the control hens. Hyline showed higher (p<0.05) egg production than Shaver when ambient temperature was controlled by the desert cooler. Line had no significant effects on egg weight and egg mass. The net income per hen in the cooled house was US $ 6.80/hen compared to US $ 4.20/hen for the controls, which represented a net gain of US $ 2.60/hen more for the desert cooled hens. Based on these results, the use of desert cooler under hot conditions is efficient and economically feasible.
COMOVEMENT AND MOMENTUM

Recent evidence of excessive comovement among stocks following index additions (Barberis, Shleifer, and Wurgler, 2005) and stock splits (Green and Hwang, 2009) challenges traditional finance theory. Based on a simple model, we show that the bivariate regressions relied upon in the literature often provide little or no information about the economic magnitude of the phenomenon of interest. Instead, univariate regressions of the stock return on the returns of the group it is leaving (e.g., non-S&P stocks) and the group it is joining (e.g., S&P stocks) reveal relevant information. Moreover, results in the literature are consistent with changes in the fundamental factor loadings of the stocks. When we reexamine the empirical evidence using control samples matched on past returns and compute Dimson betas, almost all evidence of excess comovement disappears. One key element to understanding these striking results is that, in both the examples we study, the stocks exhibit strong returns prior to the event in question. Relatedly, we document the heretofore unknown empirical regularity that winner stocks exhibit increases in betas. Thus, the apparent excess comovement is just a manifestation of momentum.
Maintaining Transactional Integrity in Long Running Workflow Services: A Policy-Driven Framework

This chapter presents a framework to provide autonomous handling of long running transactions based on dependencies which are derived from the workflow. Business Processes naturally involve long running activities and require transactional behaviour across them. This framework presents a solution for forward recovery from errors by automatic application of compensation to executing instances of workflows. The mechanism is based on propagation of failures through a recursive hierarchical structure of transaction components (nodes and execution paths). The authors discuss a transaction management system that is implemented as a reactive system controller, where system components change their states based on rules in response to triggering of events, such as activation, failure, force-fail, completion, or compensation events. One notable feature of the model is the distinction of vital and non-vital components, allowing the process designer to express the cruciality of activities in the workflow with respect to the business logic. Another novel feature is that in addition to dependencies arising from the structure of the workflow, the approach also permits the workflow designer to specify additional dependencies which will also be enforced. Thus, the authors introduce new techniques and architectures supporting enterprise integration solutions that cater to the dynamics of business needs. The approach is implemented through workflow actions executed by services and allows management of faults through a policy-driven framework.

IMMUNOHISTOCHEMICAL ANALYSIS OF UROTHELIAL BLADDER CANCERS

Malignant cancers of urinary bladder are the second most common malignancy of the urinary tract and the fourth most common malignancy in general, especially in men. The aim of this study was a retrospective analysis of selected markers (p53, Ki-67 and E-cadherin) of urinary bladder cancers from the Department of Urology in Bratislava, Slovak Republic between years 2007 and 2009. We analysed 244 patients (202 males, 42 females) with diagnosed bladder cancer via cystoscopy and subsequent transurethral resection. Patients age varied from 36 to 98 years. Obtained samples were fixed by 10% buffered formalin for 24 to 48 h. Subsequently, they were dehydrated in ascending ethanol series and embedded in paraffin. The parafin sections of 5 µm were prepared by microtome and they were stained by haematoxylin and eosin. The antibodies against to p53, Ki-67 and E-cadherin were used in immunohistochemical analysis. Statistical evaluation was performed via SPSS using non-parametric Kruskal-Wallis test and p values
Rossi X-Ray Timing Explorer Observations of the Anomalous Pulsar 4U 0142+61

We observed the anomalous X-ray pulsar 4U 0142+61 using the Proportional Counter Array on board the Rossi X-Ray Timing Explorer in 1996 March. The pulse frequency was measured as ν=0.11510039(3) Hz, with an upper limit of |ν̇|≤4×10−13 Hz s−1 on the short-term change in frequency over the 4.6 day span of the observations. A compilation of all historical measurements showed an overall spin-down trend with slope ν̇=-3.0±0.1×10−14 Hz s−1. Searches for orbital modulations in pulse arrival times yielded an upper limit of axsini≲ 0.26 lt-s (99% confidence) for the period range 70 s to 2.5 days. These limits combined with previous optical limits and evolutionary arguments suggest that 4U 0142+61 is probably not a member of a binary system.
A Systematic Review of Rural Veteran Homelessness

This study is a systematic review to examine homeless veterans identified to be most at risk of unsuccessfully completing the VA’s housing program (HUD-VASH), which promotes the use of Housing First (HF) as it’s model for treating homelessness. The literature review identified those who were rural and experiencing comorbid substance use disorders (SUD) and mental health issues to likely be those who were most at risk. There were multiple reasons why this subgroup was most vulnerable including limited access to resources, higher levels of substance use and more serious mental health diagnoses, and chronic health needs. Both the literature review and systematic review in this study indicate a lack of evidence supporting Housing First especially its long-term effectiveness in the HUD-VASH program. The lack of evidence is due in part to the question of whether or not the programs examined in the literature are true HF models, which utilize all the core principles of HF. Further, the literature regarding HF predominantly measures the length of time to acquire permanent housing with little to no regard to harm reduction or rehabilitation of SUD and mental health needs. Further research is also needed to examine HUD-VASH effectiveness in treating rural veterans with comorbid SUD and mental health illnesses.

THE MANY FACES OF FOOD SUSTAINABILITY: THE OBESITY ISSUE

The paper focuses on the issue of obesi- ty, which has become one of the most insidious world epidemics and a serious threat to global health. The aim is to highlight the relationships between obesity and the sustainability of the food system and to discuss the effectiveness of different policies that could be implemented to address the problem. An empirical analysis has been carried out, aimed at assessing the relationship between price and energy density of foods and price premium for low-calorie foods. The main conclusion of the paper is that the aim of reducing obesity, which is a priority for food sustainability policies, cannot be achieved without regulatory intervention designed to reverse relative prices between obesogenic and healthy foods.
Helping babies breathe: Providing an evidence-based education intervention at a tertiary referral hospital in Liberia

Background: Helping Babies Breathe (HBB) is a neonatal resuscitation program that utilizes an active learning pedagogy to increase knowledge and skills for nurses and midwives in resource-limited areas. Two faculty members from the Tubman National Institute of Medical Arts in Liberia became certified as HBB trainers while completing a graduate nurse educator degree in the US. The aim of the current study was to use an academic program requirement for a graduate practicum and research experience to determine the effect of implementing the HBB program on the level of neonatal resuscitation knowledge and skills of students and staff at the John F. Kennedy Medical Center (JFKMC) in Liberia. Methods: The HBB program was provided to 154 participants from the JFKMC and the co-located Tubman National Institute of Medical Arts for a period of six weeks. Assessment of the participants’ neonatal resuscitation skills and knowledge included pre/post scores on multiple choice questions and evaluation of the bag and mask ventilation skills using an objective structured clinical examination (OSCE) approach. Results: Participants expressed satisfaction with the program and the skills acquired. A paired t test for the multiple choice items indicated significant knowledge difference between the pretest (2.36 ± 2.21) and posttest (15.27 ± 1.24) scores, p = . 000. On the skills checklist for OSCE A, all participants achieved final competency rates of 100% on six items, 90%- 99% on two, 70%-79% on one, and <69% on four items; on OSCE B, they achieved final competency rates of 100% on 12 checklist items, 90%-99% on one, 80%-89% on three, 70%-79% on one, and <69% on one item. Conclusions: Implementing the HBB training is an important initial step in providing delivery room staff with the skills and knowledge to reduce neonatal mortality from asphyxia. The training needs to be supplemented with additional, ongoing practice and institutional support. The model of allowing internationally educated nurses completing graduate nurse educator degrees in the US to complete practicum and research requirements at their home institution was successful. Nurse and midwifery faculty who are certified in providing the HBB can effectively provide this training. We recommend that HBB training be provided in all health care facilities in developing countries with high neonatal mortality rates.
An Efficient Hierarchical Multi-Authority Attribute Based Encryption Scheme for Profile Matching using a Fast Ate Pairing in Cloud Environment

In cloud environment, profile matching is a key technique in applications such as health care and social networks. Ciphertext-Policy Attribute-Based Encryption (CP-ABE) is suitable technique for data sharing in such environments. In this paper, we propose an asymmetric pairing based Hierarchical Multi-Authority CP-ABE (HM-CP-ABE) construction for profile matching. We utilize the fast Ate pairing to make the proposed HM-CP-ABE scheme efficient. The performance analysis of the proposed scheme shows improved efficiency in terms of computational costs for initialization, key generation and encryption using ELiPS library when compared with existing works.
Recently introduced IASP definition of ‘nociplastic pain’ needs better formulation

We welcome the recent addition of a third mechanistic descriptor, ‘nociplastic pain,’ to the IASP Taxonomy, meant to cover cases not properly covered by ‘nociceptive pain’ or ‘neuropathic pain. ’ This note doesn’t therefore question the basic rationale for introducing this new term. Thus, we accept the implication that there are at least three distinct mechanisms/processes (let’s call them nociceptive, neuropathic, and nociplastic) through which pain can arise, and that it’s important to be clear about the differences among these mechanisms for proper diagnosis even though “common mechanism(s) may be relevant”[2] in certain cases. Rather, we would like to point out the inadequacy of the formulation of the definition, which runs as follows (numbers in parentheses added by us for ease of reference):
THE EFFECT OF COMPUTER ASSISTED INSTRUCTION ON FOURTH GRADE PRIMARY STUDENTS' ACHIEVEMENTS AND ATTITUDES TOWARDS SCIENCE AND TECHNOLOGY LESSON

The aim of this study is to determine the effect of computer assisted instruction on fourth grade primary students’ achievements and their attitudes towards science and technology lesson. In this study, quasi-experimental design was utilized. There were two groups consisting of totally 55 fourth grade primary students who were selected with convenient sampling method from Korfez district of Kocaeli in Turkey. One of the groups was experimental group and the other was control group. The experimental group was taught using the computer asisted instruction based on constructivist approach and the control group was taught using constructivist approach currently used in primary education curriculum of Turkish Education System. The data were collected by means of attitude scale towards science and technology lesson (ASTSTL) and achievement test (AT). The data were analyzed using SPSS statistical packet program. The findings indicated that in terms of both achievment test and attitude scale there was a statistically significiant difference between the post test scores of the groups in favor of experimental group.
Primitive Neuroectodermal Tumour of the kidney in a young female: a case report

We present a case of a PNET of the kidney in a 20-year-old female. This is an extremely rare presentation. Primitive Neuroectodermal Tumours (PNET) occurs preferentially in the soft-tissues of the paravertebral region and chest wall, less frequently in extremities, with a male predominance. Few cases have been reported in literature with a variable, non-specific presentation and an aggressive behaviour. In our case, a radical nephrectomy with lymphadenectomy was performed. Haematoxylin and eosin staining showed the tumour composed of cohesive sheets of small, uniform, primitive cells separated by fibrous bands. Homer-Wright pseudorosettes were present and perivascular rosetting was noted. The cytoplasm showed PAS positivity. The immunohistochemical evaluation revealed a diffuse CD99 positivity in the cytoplasm of the neoplastic cells. Neuron-Specific Enolase (NSE), synaptophysin and vimentin were positive. The clinical presentation and the macroscopic aspect, together with the histological pattern, the cytological characteristics and cellular immunophenotype addressed the diagnosis towards primary PNET of the kidney. Since the differentiation of small round cell tumours may be challenging, we reviewed the difficulties in differential diagnosis. As illustrated in this case, it is important to consider the possibility of renal PNET in young female patients presenting with a renal mass.
The role of the mineral component in surface stabilization processes of a disturbed desert sandy surface

The stabilization of sandy and loamy surfaces in semiarid and arid areas by topsoil crusts protecting the soil against wind or runoff erosion is well known. Destruction of such crusts, often by overgrazing, can enhance erosion and desertification. Crust recovery does not depend purely on biotic components of the crust and vegetation. Mineral components in the initial surface stabilization process are often overlooked. The present study focuses on the relative importance of the biotic and mineral components in the process of topsoil crust recovery in a sandy desert area located in the northwestern Negev Desert of Israel. Observations of the initial crust and of the disturbed surface, in the field and under the scanning electron microscope, showed that the mineral components of the crust recovered more quickly than its biotic elements. The implications for the rehabilitation of the disturbed ecosystem are discussed. Copyright © 2002 John Wiley & Sons, Ltd.
On the limit Sobolev regularity for Dirichlet and Neumann problems on Lipschitz domains

We construct a bounded C1 domain Ω in Rn for which the H3/2 regularity for the Dirichlet and Neumann problems for the Laplacian cannot be improved, that is, there exists f in C∞(Ω¯) such that the solution of Δu=f in Ω and either u=0 on ∂Ω or ∂nu=0 on ∂Ω is contained in H3/2(Ω) but not in H3/2+ε(Ω) for any ε>0 . An analogous result holds for Lp Sobolev spaces with p∈(1,∞) .
Effect of starter cultures on the anti-nutrient contents, minerals and viscosity of ogwo, a fermented sorghum-Irish potato gruel.

This work investigated the effect of single starter cultures on the anti-nutrient, mineral contents and viscosity of fermenting ‘ogwo’, a fermented gruel from sorghum-Irish potato mixture. The organisms used were Lactobacillus acidophilus, L. fermentum, L. plantarum, Geotrichum candidum and Saccharomyces cerevisiae. There were significant reductions (P < 0.05) in the anti-nutrient contents of the samples fermented with starter cultures than the sample fermented naturally. The highest reductions were observed in phytic acid, saponin and flavonoid contents of L. plantarum fermented sample and in oxalate and tannin contents of sample fermented with S. cerevisiae and L. acidophilus respectively. Sodium, Calcium, Phosphorus, Copper and Manganese contents of ‘ogwo’ produced with starter cultures increased while fluctuations were observed in their Potassium, Magnesium and Zinc contents. The viscosities of the starter culture fermented samples reduced more than the naturally fermented sample with the highest and lowest reductions in L. fermentum and L. plantarum respectively. The results of this work showed that Lactobacillus and yeasts were good candidates for reducing the anti-nutrient contents and the viscosities as well as improving the mineral contents of the gruel.
Designing for inclusiveness - immersive workshops as gathering data tool

This paper presents a brief description of four workshops designed as part of the research “Inclusive Informatics School for Blind Students”. The workshops were designed with double objectives, as an introduction for the process of inclusion of blind students in Informatics Schools and as tool for gathering data for the research. In this paper we will discuss them from the point of view of the second objective. The workshops were conducted in Universidad Nacional (UNA) in Costa Rica with the participation of teachers from Informatics School, with blind students from UNA and teachers from other careers with previous experiences with blind students. The workshops provided valuable information to construct data for the global research.
