A biomechanical invesitgation of the surface stress of a synthetic femur using infrated thermography validated by strain gauge measurements

As the North American population ages, there will be a massive increase in musculoskeletal impairments because these problems are most common in the elderly. A very common condition is osteoporosis, which can result in fractures. Therefore, the need for improved orthopaedic fracture repair implants is vital. Currently, the two main approaches in studying orthopaedic implants are strain gauge measurements and finite element modelling. This study introduces and validates a relatively new, non-destructive approach in analysing stress patterns in a biomechanics application. Lock-in infrared (IR) thermography calibrated with strain gauges was used to investigate the stress and strain patterns of a synthetic femur under dynamic loading. The femur was instrumented with strain gauges and tested using axial average forces of 1500N, 1800N, and 2100N at an adduction angle of 7 degrees to simulate the single-legged stance phase of walking. Three dimensional surface stress maps were obtained using an IR thermography versus strain gauge data with a Pearson correlation of R² = 0.99 and a slope ranging from 0.99 to 1.08, based on thermoelastic coefficient (Km) ranging from 1.067 x 10⁻⁵/MPa to 1.16 x 10⁻⁵/MPa, for the line of best fit. IR thermography detected bone peak stresses on the superior-posterior side of the femoral neck of 91.2MPa (at 1500 N), 96.0Mpa (at 1800 N), and 103.5MPa (at 2100 N). There was strong correlation between IR measured stresses and force along the anterior (R² = 0.87 to 0.99), posterior (R² = 0.81 to 0.99) and lateral (R² = 0.89 to 0.99) surface. This is the first study to provide an experimentally validated three dimensional stress map of a synthetic femur using IR thermography.

IgG antibodies for Toxoplasma, Rubella, CMV & HSV were found in 25 (58.14%), 29 (67.44%), 31 (72.09%) and 29(67.44%) respectively. Conclusion: Routine antenatal screening for TORCH antibodies for women with bad obstetric for early diagnosis and proper management is suggested.
Selecting Observational Studies for Comparing Medical Interventions

Comparative Effectiveness Reviews are systematic reviews of existing research on the effectiveness, comparative effectiveness, and harms of different health care interventions. They provide syntheses of relevant evidence to inform real-world health care decisions for patients, providers, and policymakers. Strong methodologic approaches to systematic review improve the transparency, consistency, and scientific rigor of these reports. Through a collaborative effort of the Effective Health Care (EHC) Program, the Agency for Healthcare Research and Quality (AHRQ), the EHC Program Scientific Resource Center, and the AHRQ Evidence-based Practice Centers have developed a Methods Guide for Comparative Effectiveness Reviews. This Guide presents issues key to the development of Comparative Effectiveness Reviews and describes recommended approaches for addressing difficult, frequently encountered methodological issues. The Methods Guide for Comparative Effectiveness Reviews is a living document, and will be updated as further empiric evidence develops and our understanding of better methods improves. Comments and suggestions on the Methods Guide for Comparative Effectiveness Reviews and the Effective Health Care Program can be made at www.effectivehealthcare. ahrq.gov. None of the authors has a financial interest in any of the products discussed in this document. The views expressed in this paper are those of the authors and do not represent the official • Systematic reviewers disagree about the ability of observational studies to answer questions about the benefits or intended effects of pharmacotherapeutic, device, or procedural interventions. • This paper provides a framework for decisionmaking on the inclusion of observational studies to assess benefits and intended effects in comparative effectiveness reviews • Comparative effectiveness reviewers should routinely assess the appropriateness of inclusion of observational studies for questions of benefit, and the rationale for inclusion or exclusion of such studies should be explicitly stated in reviews. • In considering whether to use observational studies in CERs for addressing beneficial effects, reviewers should answer two questions: o Are there gaps in the evidence from randomized controlled trials? o Will observational studies provide valid and useful information?
Comparison of the Level of Awareness of Family Planning Measures in the Urban and Urban-slum Women

Abstract The present study was done for the comparison of the level of awareness of family planning measures in the urban and urban-slum of Jammu (Jammu and Kashmir State). The sample of the study was divided into two groups’ i.e. urban women and urban-slum women. The sample size consisted of 30 women; 15 women from urban community and 15 women from urban-slum community in the age group of 25-35 years were selected for the purpose. Purposive sampling technique was used for selecting the sample. The data was collected with the help of Interview schedule. Findings of the study indicate that women from the urban as well as urban-slum community were aware about the family planning measures but in urban areas majority of the women used pills, IUD, where as in urban-slum community majority of the men used family planning measures like condom. The failure rate of family planning measures was high in the urban-slum community. Women from the urban community had good attitude regarding the use of contraceptives and they were satisfied as per their view the use of these measures was considered not only best for spacing the children but also had helpful in maintaining a healthy and tension free life. The result also reveals that each and every family planning methods had some side effects.
Evaluation of the Effects of Mozart Music on Cerebral Hemodynamics in Preterm Infants

Preterm infants, as a special population, exposed to the stimulus of medical procedures, need efficient integrated care. Music, a non-invasive positive stimulus, has the ability to improve infants well-being. In this study, a randomized controlled trial was conducted to evaluate the effect of Mozart music on cerebral hemodynamics detected by functional near-infrared spectroscopy (fNIRS). The statistical analysis results showed that the sample entropy of the experimental group was significantly lower than that of the control group in resting state after music intervention. It suggested that Mozart music could achieve the effect of calmness and relaxed state correlated with lower brain activities. This study will provide evidence to support the wide application of music intervention in clinical practice.
Influence of Critical Parameters in Lumped-Parameter Thermal Models for Electrical Machines

This paper investigates the influence of some critical parameters in lumped parameter thermal network (LPTN) models for electrical machines. Even though the conduction thermal resistances in LPTN models are well defined by analogy to electric circuit, some critical convection thermal resistances are still difficult to compute and usually determined by empirical rules based on the previous publications. Thus, these parameters, including the equivalent thermal resistance between the frame and the ambient, and the convection coefficients within the machine, e.g. between the frame and the inner air, the end-winding and the inner air, the rotor and the inner air, as well as the equivalent airgap thermal resistance, etc., are discussed and evaluated. Moreover, the winding models and the estimation of the equivalent thermal conductivity are also discussed. Based on a totally enclosed natural cooled interior permanent magnet synchronous machine, a thermal analysis software package Motor-CAD is employed in this paper to provide a reference for comparison.
A Framework For An Artificial Neural Network Enabled Single Pixel Hyperspectral Imager

Compressive Sensing enables improvement of acquisition of a variety of signals in various applications with little to no discernible loss in terms of recovered image quality. The current work proposes a signal processing framework for the acquisition and fast reconstruction of compressively sampled hyperspectral images using an artificial neural network architecture. This ANN-based approach is capable of performing a fast reconstruction by avoiding the requirement of solving a computationally intensive image-specific optimization problem. The proposed framework contributes to advance singlepixel hyperspectral imaging device methodologies, which enable a significant reduction in device mechanical complexity, imaging rate, and cost. Our experiments demonstrate that a hyperspectral image can be reconstructed using only 10% of the samples without compromising classification performance. Specifically, the results show that classification performance of the compressively sampled hyperspectral image recovered using artificial neural networks is equal or higher to that of those obtained using current scanning hyperspectral imaging platforms.
Too late to get healthy? A behavioural analysis of the diet-health relationship in the older Italian population

The continuous aging of the EU population challenges the sustainability of welfare states. Part of the solution is to ensure that people not only live longer but also better (i.e., that they can function independently while remaining free of disease/disability), which may be achieved through better nutrition and adoption of healthier lifestyles. We test that proposition with a behavioural model of diet quality choice and health determination. The simultaneous equations model, which accounts for the endogeneity of lifestyle choices and is applied to a sample of older Italians, allows for bi-directional causality between diet and health. The health production function confirms that good quality diets and other healthy lifestyles (e.g., physical activity, smoking and drinking) improve self-assessed health. In turn, the elderly respond to illness by improving their diets and exercising more. Supporting healthy aging may be achieved through targeted policies aimed at promoting healthy eating and other healthy lifestyles.
Thermal Analysis on IGBT Module Based Rotor Side Coverter of Doubly-fed Wind Turbine by Considering Inter-harmonic Current

When the connected grid is under sub-synchronous or low frequency oscillation, doubly-fed wind turbines are susceptible to grid background harmonics because the stator is directly connected to the power grid. Due to the coupling between stator and rotor magnetic fields, inter-harmonic currents (IHC) could be induced in rotor windings. However, the traditional analysis on loss and junction temperature of insulated gate bipolar transistor (IGBT) modules is considered only the fundamental current. In this paper, the effect of IHC on loss and junction temperature of IGBT modules in rotor side converter is studied. Firstly, the analytical model of rotor IHC is derived. Then, the calculation method of power loss and junction temperature is presented by considering IHC. Further, the power loss and junction temperature with and without rotor IHC are obtained. The comparison results show the IHC could result in the increase of the power loss and the junction temperature of IGBT module, especially for the low frequency IHC.
Experimental Outcomes of the Mediterranean Diet: Lessons Learned from the Predimed Randomized Controlled Trial

The Mediterranean Diet (MD) is, culturally and historically, the nutritional pattern shared by people living in the olive-tree growing areas of the Mediterranean basin. It is of great importance for its potential preventive effect against cardiovascular diseases (CVDs). The PREvención con DIeta MEDiterránea (PREDIMED) study, a Spanish multicentre randomised controlled trial (RCT), was designed to assess the long-term effects of the MD, without any energy restriction, on the incidence of CVD in individuals at high cardiovascular (CV) risk. Since its inception, it gave a great contribution to the available literature on the issue. It is well known that, in the field of the health sciences, RCTs provide the best scientific evidence. Thus, the aim of the present review is to analyse the results of the RCTs performed within the frame of the PREDIMED study. Our findings showed that MD has beneficial effects in the primary prevention of CVDs, diabetes and in the management of metabolic syndrome.
Investigation on A New Double-sided Permanent Magnet Linear Switched Reluctance Motor

A new double-sided permanent magnet linear switched reluctance motor (PMLSRM) for the major propulsion of an elevator is proposed and investigated in this paper, in which the armature coils and the permanent magnets (PMs) are all located on its primary. The long double-sided secondary is made of iron only, which makes the structure robust and low-cost. The working principle of the PMLSRM is introduced first and two kinds of the motor with series and parallel magnetic circuits are proposed, investigated and compared. Then, we compare the proposed PMLSRM with the LSRM without PMs assisted on the primary in terms of the electromagnetic characteristics. The result shows that the proposed motor is less likely to be saturated under the same excitation which means it could exhibit higher thrust force among large current density range.
Low Serum Paraoxonase-1 Lactonase and Arylesterase Activities in Obese Children and Adolescents

Abstract Serum paraoxonase-1 (PON1) binds mainly to high density lipoproteins (HDLs) and protects low density lipoproteins (LDLs) against oxidation. While paraoxonase and arylesterase activities are traditionally assayed, lactonase activity, accounting for protection against LDL oxidation, was less investigated in obese children and adolescents. Therefore, we aimed to measure lactonase, paraoxonase and arylesterase activities, oxidized LDL (ox-LDL) and malondialdehyde (MDA) levels in obese children and adolescents. Study population included 68 children (35 obese and 33 normal-weight). Arylesterase and paraoxonase activities were assayed spectrophotometrically. Lactonase activity, ox-LDL and MDA levels were measured using a pH-sensitive colorimetric assay, an ELISA technique and a fluorimetric method, respectively. The lipid profile was assessed by common methods. Lactonase and arylesterase activities were decreased in the presence of obesity. MDA, but not ox-LDL levels, showed significant differences between groups. Multiple regression analysis identified a reciprocal relationship and a possible association between lactonase and arylesterase activities and obesity.
SEARS: A Statistical Error and Redundancy Analysis Simulator

Manufacturing a DRAM chip involves multiple steps. External impurities, faulty deposition, or manufacturing errors in any of these steps could generate chips with faulty memory cells, rendering the chip unusable. To overcome these faulty memory cells, redundancies are included in the memory, allowing mapping of faulty memory cells to these redundant cells. The process of mapping faulty cells to redundant cells is called Redundancy Analysis (RA). Different RA algorithms have been developed and are often tested on randomly generated defect to test their efficiency and execution time. But in real life, the defect pattern of a chip is not completely random, it follows a distribution pattern and the algorithms should be tested on chips with similar error distribution patterns. So, in this paper, we propose a Statistical Error and Redundancy Analysis Simulator to generate defects on the chips similar to defects on the manufacturing line. These chips are tested with existing RA algorithms to analyze their performance. The simulated errors on the chips are based on statistical models derived from real data. After generating defects on the chip, execution, comparison and benchmarking of algorithms based on yield and execution time is done. The simulator gives insights on algorithm behavior with different kinds of memory architectures and defect patterns. This allows designers of memory architecture and RA algorithm to simulate and predict wafer yield for different RA algorithm designs and memory architectures before manufacturing a new memory device.
Playful Security: A Computer Game for Pairing Devices

The secure “pairing” of wireless devices based on out-of-band communication is an established research direction. Unfortunately, this approach is prone to human errors that lead to man-in-themiddle attacks. To address this and to better motivate the users, this paper proposes the use of computer games for pairing. Games make the pairing process enjoyable and engaging, thus improving its usability and security. The technical contribution of this work is a new pairing system called “Alice Says. ” This is a game that achieves pairing based on the memory game Simon. The paper discusses the design and implementation of Alice Says. On a broader note, the paper also points to other problems in wireless and mobile security that are currently lacking optimal solutions, and suggests how games and entertainment can be applied to improve them.
Research on primary health care: a multidisciplinary project in Ghana.

A multidisciplinary study was undertaken in Ghana in 1976-77 by the Health Group of the Institute of Development Studies of the University of Sussex to study the possibilities of developing a primary health care strategy in Ghana. Studies of the technical activities and economic and organizational efficiency of the existing rural health service the allocation of health care resources and sociological factors impinging on potential community participation were undertaken mainly in the Jasikan and Birim districts. In recent years the Ghana government has allocated 7-9% of the national budget for the health sector but inflation and population growth reduced the real allocation per capita by 11% between 1970 and 1977. Health service resources are distributed unevenly with hospitals and urban areas benefiting disproportionately. 1/3 to 1/2 of the population of the 2 study districts lived over 10 km from the nearest primary care activities. Most of the health units studied failed to provide a full range of services. Deficiencies in provision of services and quality of care appear to be due to many factors including lack of personnel transport drugs and vaccines and other resources; lack of correspondence between staff training and actual work; inadequate supervision and support and inadequate integration in the health care system; and poor morale of workers. Cost effective prescribing of drugs could reduce the units pharmaceutical expenditure to about 1/3 of present costs. The village research highlighted the need for a primary health care system relevant to the reality of peoples lives and socioeconomic situation. Recommendations of a workshop organized by the Ministry of Health to discuss the study findings are presented.
Comparison of creeping discharges propagating over pressboard immersed in olive oil, mineral oil and other natural and synthetic ester liquids under DC voltage

This paper presents an experimental study on the characteristics of creeping discharges propagating over pressboard immersed in olive oil, rapeseed oil, tetra-ester, methyl oleate, and mineral oil, under both negative and positive DC voltages. The investigated characteristics are mainly the shape of discharges and their stopping lengths. Two experimental test cells are used: in the first one, the pressboard is inserted between pointe and plane electrodes so that the tip is perpendicular and at the center of the pressboard sample; and in the second one, the pressboard is placed between a point and bar electrodes in a way that allow a propagation in one direction (tangentially to pressboard). It is observed that the creeping discharges under DC voltage are not radial. Their shapes are different from those observed in previous work under AC and lightning impulse voltages. On the other hand, for given voltage and pressboard thickness, the stopping length Lf is shorter when the point is negative than when it is positive indicating that the flashover voltage will be greater with a negative point This also evidences a difference in the processes involved in each polarity especially the space charge resulting of the injected charges and the charge accumulated at the interface (including the charges resulting of double layer) as well as the evolution of the electric field in the vicinity of the point electrode and along the pressboard surface. For a given pressboard thickness, Lf increases with the voltage; it decreases when the thickness of pressboard is reduced.
Hot Event Detection for Social Media Based on Keyword Semantic Information

Statistical features are commonly used to detect hot events in social media. However, these features cannot represent the semantic similarity of synonym expression. Aiming at this problem, a semantic keyword-based hot event detection method for social media is proposed in this paper, which includes a semantic keywords model to distinguish real-world events from hot topics. The clusters are found using Affinity Propagation with statistic features. Also, related discussions from different perspectives of the event are merged using word embedding. After that, news titles and posts of hot topics are employed to train the semantic keywords model. This model is used to distinguish real-world events from clusters. Experiments show the proposed method can find hot events from social media data and related posts for further research.
