Effect of HMDS-modified silica aerogel nanoparticles on ATRP of styrene and methyl methacrylate: Kinetics and thermal studies

Surface of pristine silica aerogel nanoparticles was hydrophobically modified with hexamethyldisilazane (HMDS). Then, the resultant modified nanoparticles were used for in situ atom transfer radical copolymerization of styrene and methyl methacrylate. Surface area and structural characteristics of the HMDS-modified silica aerogel nanoparticles (H-SANs) were examined by nitrogen adsorption/desorption isotherm. Evaluation of size distribution and morphological studies were also performed by scanning electron microscopy and transmission electron microscopy. Conversion and molecular weight determinations were carried out using gas chromatography and size exclusion chromatography, respectively. Adding of H-SAN by 3 wt% results in decrement of conversion from 98% to 79%. In addition, molecular weight of copolymer chains decreases from 20,372 g·mol−1 to 16,487 g·mol−1. However, polydispersity index values increases from 1.38 to 1.76. Linear increase of ln(M0/M) with time for all the samples shows that polymerization proceeds in a living manner. Increasing thermal stability of the nanocomposites is demonstrated by thermal gravimetric analysis. Differential scanning calorimetry shows a decrease in glass transition temperature from 67.4°C to 59.8°C by the addition of 3 wt% of the H-SAN.
The European Union, Sport Policy and Health-Enhancing Physical Activity (HEPA): The Case of Exercise by Prescription

In the classical European cultural tradition sport and physical activity (PA) are essential to human development and wellbeing. The entry into force of the Lisbon Treaty in 2009 allowed the EU, for the first time, to establish a new sport policy framework which can be used to support a Health-Enhancing Physical Activity (HEPA) agenda. The need of this framework is founded in the huge disparities in PA and sport within the EU: when citizens of the Nordic countries and the Netherlands are the most physically active, the citizens of Mediterranean countries and the 12 new Member States tend to exercise less than average, the range is from 72 % to 18 % of the EU state populations performing sports at least with some regularity (Germany 49 %). When it comes how many citizens report general or almost physical inactivity the range is between Denmark (15 %) and Italy (63 %) with (Germany 22 %). The Commission’s proposal for an EU Council monitoring mechanism would allow to compare and coordinate Member States’ sport policies to service HEPA needs better as part of the EU PA guidelines from 2008. PA on prescription is part of these guidelines. As an educational and political project, the HEPA concept is to exchange knowledge and good practice allowing this to happen across the EU. summary ZusammeNfassuNg
The Resolution of Social Conflict between Friends.

NELSON, JANICE, and ABOUD, FRANCES E. The Resolution of Social Conflict between Friends. CHILD DEVELOPMENT, 1985, 56, 1009-1017. The major question addressed was whether children respond differently to conflict with a friend than with a nonfriend. Third and fourth graders were pretested on their answers to social problems. They were then randomly assigned to a friend or nonfriend acquaintance who initially agreed or disagreed with their answer to a problem, and asked to discuss this problem with their peer. 2 variables were measured and analyzed: the content of the discussion, and the change in answer to the problem from before to after the discussion. Results indicated that friends gave more explanations of their position and more criticism of their partner than nonfriends. Disagreement provoked more change than agreement. Among the disagreeing pairs, although friends did not differ from nonfriends in the amount of change made to their answers, they changed to a more mature solution than nonfriends. These results support the view that conflict between friends promotes more social development than conflict between nonfriends.
Effects of pore water pressure on cohesive-frictional slope stability by limit analysis

In the region there was generally influenced by seasonal weather such as highly rainfall intensity, the slope failure will be influenced by the existence of water and these conditions may trigger the changing of failure surface on the slope. The increasing pore water pressure causes shear strength reduction and shear stength enhancement. Consequently, the water level changes need to be evaluated conscientiously. In this paper, the various water levels are applied to perform the different pore water pressure conditions below the ground surface. Many methods are commonly used to predict the slope stability failure mechanism, including limit analysis. Limit analysis has been more widely employed for stability assessment in recent years because of its accuracy. In limit analyses, gravity multiplier will be adopted in this paper by using two-dimensional (2D) numerical approach to identify the failure mechanism. The results will be verified by comparing this study to previous studies.
SLEEP AND NEURODEGENERATIVE DISORDERS

The coexistence of neurodegenerative diseases and sleep disorders is increasingly being recognized. While there is considerable evidence suggesting that such conditions are inherent to the neurodegenerative process, most occur as a result of numerous intrinsic and extrinsic factors. Primary sleep disorders such as obstructive sleep apnea increase in prevalence with age and can result in unique clinical scenarios when combined with neurodegenerative diseases. REM sleep behavior disorder seems to exhibit a predilection for specific neurodegenerative entities and may therefore have diagnostic utility and ultimately prove to be a useful marker to identify those disorders best suited for studies investigating preventive therapies. Identification of all factors affecting sleep disturbances is important because sleep complaints significantly influence the rate of institutionalization in elderly individuals. This review highlights various pathophysiologic and clinical investigations concerning sleep findings in neurodegenerative diseases.
Data Management Knowledge, Practice and Associated Factors of Ethiopian Health Extension Workers in Gamo Gofa Zone, Southern Ethiopia: A Cross-Sectional study

Background: Producing quality data for decision at all levels of the health system is a global imperative. According to the assessment of the Ethiopian National Health Information System done by the Federal Ministry of Health and World Health Organization, health information system resources, data management, dissemination and use were rated as “not adequate” among the six major components. The aim of this study was to determine the level of data management knowledge, practice and associated factors among Health Extension Workers. Method: An institution based cross-sectional study was conducted from March 1-22, 2012, among Health Extension Workers deployed in Gamo Gofa Zone, Southern Ethiopia. A cluster sampling technique was used to select a sample of 457 participants. A structured self- administered questionnaire was used to collect the data. Data were entered using EPI info version 3.5. 3 and analyzed using SPSS version 20 statistical packages. Descriptive statistics were used to describe the study population in relation to relevant variables. Bivariate and multivariate logistic regression was also carried out to see the effect of each independent variable on the dependent variable. Results: The study revealed that 58.2% of study participants had good data management knowledge and nearly three-quarters (74.3%) had a good data management practice. Workers who were supervised every 3 months [AOR= 4.204, 95% CI: (1.372-12.885)] and workers who have reporting formats in their office [AOR=2.631, 95% CI: (1.331- 5.203)] were more likely to have good data management knowledge. Moreover, workers who have of data registration books and reference materials in their office were more likely to have good data management practice with [AOR= 5.661, 95%CI: (2.019-15.874)] and [AOR=1.870, 95% CI: (1.178-2.968)] respectively. Conclusions: Data management knowledge was found to be low whereas, data management practice was found to be high in the study area. Availability of reporting formats and frequency of supervision for data management knowledge, and availability of reporting formats and data registration book for data management practice of respondents were identified as significant determinants. Therefore, supplying adequate data management resources, modifying formats and improving frequency of supervision are necessary tasks to improve the data management knowledge and practice of Health Extension Workers in Ethiopia.
Born this way? A review of neurobiological and environmental evidence for the etiology of psychopathy

Abstract Across a significant body of research, psychopathy has often been conceptualized as a biologically based malady. In this research, genetic and neurobiological differences have been conceptualized to underlie psychopathy, while affected individuals’ life experiences only influence expressed psychopathic features and their severity. Psychopathy research has largely ignored developmental evidence demonstrating significant influences of environment on both biological and behavioral processes, resulting in several prominent criticisms (Edens & Vincent, 2008; Loeber, Byrd, & Farrington, 2015). The current review was conducted with two main aims: (a) to collect and consider etiological evidence from the extant body of research on genetic and neurobiological factors in psychopathy; and (b) to evaluate findings from genetic, neurotransmitter, brain structure, and brain function studies in the context of relevant evidence from developmental research. Examples from research on adversity and traumatic stress, a common correlate of psychopathy, were used to highlight current research gaps and future directions to aid in the integration of developmental and neurobiological research agendas. While some promising evidence exists regarding possible underlying neurobiological processes of psychopathic traits, this evidence is insufficient to suggest a largely biological etiology for the disorder. Further, information from developmental and epigenetic research may suggest complex, multidimensional trajectories for individuals experiencing psychopathy. Based on these observations, the authors make several recommendations for future research, as well as for current clinical application and practice.
CNT EUV pellicle: balancing options (Conference Presentation)

As EUV lithography wafer volumes increase, throughput and yield require more focus. Yield can be enhanced by introducing a pellicle to hold particles out of the focal plane and minimize their impact to imaging. Using a pellicle also minimizes the extra wafer inspections required to ensure that printable mask defects do not increase over time. However, if the associated transmission loss is high, the yield advantage is offset by reduced throughput. The CNT-based pellicle offers the advantage of very high EUV transmission. CNT pellicles have also demonstrated lifetime at 300W EUV scanner power. The challenge is balancing the CNT membrane design in three areas: physical presence/the ability to stop particles, EUV transmission/imaging impact, and lifetime in the scanner/thermal tolerance. Each of these areas will be described along with simulated and experimental data illustrating the value of a CNT-based EUV pellicle solution for the future.
CO 52 (IET 25487): A highly remunerative medium duration fine grain rice variety

In Department of Rice, Tamil Nadu Agricultural University, Coimbatore, a medium duration fine grain rice variety CO52 was released for cultivation in transplanted situation for late samba / thaladi season . CO52 rice variety recorded a mean grain yield of 6191 kg/ha and possessess quality grain traits comparable to the predominantly cultivated fine grain types. It is a derivative of the cross between BPT 5204 and CO(R) 50 which matures in 130-135 days. The variety was tested in the station trial for three (2009-2011)years, Multi Location Trial for two (2011-12 and 2012-13) years, Adaptive Research Trial for two (2013-14 and 2014-15) years, OFT for three (2013-14, 2014-15 and 2015-16) years and in AICRIP trial for two (2011 and 2015) years. CO52 variety is moderately resistant to insect pests viz., plant hoppers and leaf hoppers and diseases viz., blast, sheath rot, brown spot and sheath blight. It produces medium slender white rice with high milling percentage, high head rice recovery, high linear elongation ratio, intermediate amylose content, soft gel consistency and moderate gelatinization temperature indicating its suitability for cooking with a remunerative market price and consumer preference similar to Improved White Ponni and BPT 5204.
Drug Transporters and Multiple Drug Resistance in the Most Common Pediatric Solid Tumors

Solid tumors account for approximately 30% of all pediatric cancers. Although chemotherapy has largely contributed to strongly improve patient outcome, multidrug resistance (MDR) remains one of the major mechanisms limiting the overall survival. The enhanced efflux rate of chemotherapeutic drugs from tumor cells through drug transporters is one of the most important mechanisms of MDR. Drug transporters play a pivotal role in preserving the balance between sensitivity and resistance of tumor cells to anti-neoplastic drugs. Their functional activities have been barely investigated in pediatric solid malignancies. Here, we provide evidence from the current literatures on drug transporters and MDR in the most common types of pediatric solid tumors, including neuroblastoma, Wilms’ tumor, rhabdomyosarcoma, retinoblastoma, medulloblastoma and hepatoblastoma.
Frequency-dependent anisotropy in partially saturated rocks

Seismic wave propagation through fractured rocks is greatly influenced by the fracture system and fluid content. This has become increasingly apparent from recent laboratory measurements and field observations which have shown evidence that seismic anisotropy varies systematically with frequency and fluid saturation. Exploiting this behaviour for reservoir characterization relies on the availability of adequate theoretical rock physics models. Many previous theories on frequency-dependent anisotropy have been limited to the single fluid assumption, despite the fact that almost all reservoirs are partially saturated. This thesis focuses on improving the understanding of multiphase saturation effects on anisotropic seismic wave response in reservoirs containing aligned fractures. I do this by theoretically deriving expressions for the anisotropic frequency-dependent elastic constants. These depend on the relative mobilities of the saturating fluids and the coupled impact of ‘squirt flow’ and ‘patch saturation’ effects, which have previously been considered independently, on anisotropic seismic wave propagation. The effect of relative permeability is pronounced; fluid mobility can be lower in partially saturated rocks compared to the fully saturated case, and this can lead to a stiffening which dominates compressibility effects. This can result in unexpected non-monotonic relationships between moduli and water saturation, complicating attempts to invert saturation from seismic data. I test the theory against laboratory measurements carried out at the National Oceanography Centre, Southampton (NOCS) of S-wave splitting and P-wave anisotropy in synthetic fractured sandstones saturated by mixtures of both water/air and brine/CO2. I demonstrate that both squirt and patch mechanisms are significant for the interpretation
Lopinavir/ritonavir + tenofovir Dual Therapy versus Lopinavir/ritonavir-Based Triple Therapy in HIV-Infected Antiretroviral Naïve Subjects: The Kalead Study

Purpose: With reference to the clinical need for simple, potent and safe antiretroviral regimens, Lopinavir/ ritonavir + tenofovir (LPV/r+TDF) two-drug initial regimen was studied for efficacy and safety in HIV-infected patients. Methods: Kalead was a prospective, randomized, open-label, 72-week trial comparing LPV/r+TDF versus LPV/r+ two (non-TDF) NRTIs in HIV-infected adults with HIV-RNA >400 copies/mL and any CD4 count. Primary endpoint was the proportion of subjects with HIV-RNA <50 copies/mL at week 72. Results: 152 subjects were randomized. Eleven (15.3%) subjects in the dual therapy arm and seven (8.8%) in the triple therapy arm who did not achieve HIV-RNA <50 copies/mL at least twice prior to and including week 24 were discontinued per protocol (p=0.21). Overall discontinuations were 41.7% and 43.8% in the dual therapy and triple therapyarms. At week 72, 51.4% and 52.5% of subjects in the dual therapy and triple therapy arms had HIV-RNA <50 copies/mL (p=0.89, ITT, NC=F). In an on-treatment analysis, 87.2% and 93.0% of subjects in the dual therapy and triple therapy arms had a HIV-RNA <50 copies/mL (p=0.47). Over 72 weeks of therapy, mean CD4 count increases were greater in the dual therapy arm (+332 cells/mm3 vs +234 cells/mm3, p=0.01). Adherence, overall incidence of adverse events, drugrelated adverse events, and Grade I-IV laboratory abnormalities were comparable between the two arms. Conclusions: A two-drug regimen of LPV/r+TDF suggests sufficient safety and efficacy warranting further investigation. However, high discontinuation rate and study design limitations restrict overall interpretation.

Analysis of Spring-in for Composite Plates Using ANSYS Composite Cure Simulation

Process induced dimensional changes in composite parts has been the topic of interest for many researchers. The residual stresses that develop in fiber-reinforced laminates during curing process while the laminate is confined to the process tool often leads to dimensional changes such as spring-in of angles and warpage of flat sections. Many experimental studies have put emphasis on this issue and various researches show different methods to predict these dimensional changes. The traditional trial-and-error approach can work for simple geometries, but composite parts with complex shapes require more sophisticated models. When composite laminates are subjected to thermal stresses, such as the heating and cooling processes during curing, they can become distorted as the difference between the in-plane and the through-thickness thermal expansion coefficient, as well as chemical shrinkage of the epoxy, causes the enclosed angle of curved sections and angle components to be reduced. Distorted components can cause problems during assembly, significantly increasing production costs and affecting performance. This paper focuses on predicting these shape deformations using software simulation of composite manufacturing and curing. Various factors such as resin shrinkage, degrees of cure, difference between coefficient of thermal expansion of mold and composite are taken into consideration. A cure kinetic model is presented which illustrates the matrix behavior during cure.
Dimensional Stability of Cement Bonded Boards Produced from Thaumatococus danielli Stalk

Cement bonded boards 6 mm thick were produced using Thaumatococcus daniellii stalk. Thaumatococcus daniellii and cement were mixed together at two different mixing ratios and three board densities of 2.5:1 and 3:1 and 500, 600 and 700 g/cm, respectively. After 24 h of cold-water immersion, the mean water absorption of the cement bonded board ranged from 22.9 to 48.5% for (cement/stalk) mixing ratio of 3:1 and 2.5:1 with board density 700 and 500 g/m 3 respectively. Cement bonded board produced from the highest levels of cement: stalk ratio (3:1) and board density (700 g/cm 3 ) were dimensional more stable as they had the lowest value for water absorption. The least dimensionally stable boards were produced from the mixing ratio cement: stalk ratio (2.5:1) and board density (500 g/m). The mean values obtained for thickness swelling (TS) after 24 hours of cold-water immersion ranged from 0.19 to 0.74%. Result shows that the Original Research Article Adelusi et al.; JMSRR, 4(2): 1-7, 2019; Article no.JMSRR. 51497 2 higher the increase in mixing ratio of cements to fibre (3:1) and board density (700 g/cm) caused decrease in thickness swelling and water absorption. From this study, Thaumatococcus daniellii stalk proved to be suitable for the production of cement–bonded board.
Building-Related Illness

Building-related illnesses represent a spectrum of disease. Important to their genesis are the unique features of the indoor air environment involving exposures to air pollution, mold spores, and various allergens. Specific building-related illnesses are primarily infectious, but also include the phenomenon of hypersensitivity pneumonitis and exacerbations of bronchial asthma, chronic obstructive pulmonary disease, and other chronic respiratory diseases. Nonspecific building-related illness includes an array of common symptoms but has no objective findings. It is found among a varied and susceptible working population.

Effects of cutting parameters on surface quality in hard milling

ABSTRACT Surface and subsurface microstructure evolution are particularly highlighted in dry machining of hard-to-cut materials. In this research, a user-defined subroutine integrated into an established finite element (FE) cutting model for AISI H13 steel was developed to simulate dynamic recrystallization (DRX) and surface microhardness variation in the hard milling process. At first, the hierarchical structure of tempered martensite transformed from prior-austenite was analyzed and the initial effective grain size was identified. Secondly, the material sub-model used for DRX and microhardness prediction on the basis of empirical formulas of Zener-Hollomon (Z-H) and Hall-Petch (H-P) was presented. Then, the user-defined subroutine programmed in software FORTRAN adapted from the proposed sub-model was incorporated into a verified 2D cutting simulation model to explore the effects of cutting parameters. Finally, hard milling experiments and corresponding microstructure characterization were performed to verify the grain size changes and microhardness variation. Comparison results confirmed the validity of the presented sub-model for microstructure characteristics prediction aiming at grain size and microhardness.
