Comparison of GO, GO/MWCNTs composite and MWCNTs as potential electrode materials for supercapacitors

We report the synthesis of graphene oxide/multi-walled carbon nanotube (MWCNT) composites employing an alternative and novel approach for possible application as supercapacitor materials in energy storage devices. Integrating these nanostructures resulted in a strong synergistic effect between the two materials consequently leading to a robust and superior hybrid material with higher capacitance compared to either graphene oxide or MWCNTs. Specific capacitances of 251, 85 and 60 F g−1 were obtained for graphene oxide-multi-walled carbon nanotubes, MWCNTs and graphene oxide, respectively, in a potential range from −0.1 to 0.5 V. Most importantly, a 120% increase in capacitance was observed with increasing cycle number at 20 mV s−1. The ease of synthesis and the exceptional electrochemical properties make the use of this nanostructure an attractive, alternative way of designing future supercapacitors in both conventional fields and new emerging areas.
In silico protein prediction of the 16S ribosomal RNA gene from novel rhizobacterium Bacillus cereus UPMLH24

In this study, computational methods were used to predict information hidden in the small subunit 16S rRNA gene from newly isolated plant growth-promoting rhizobacteria B. cereus strain UPMLH24. In the present study, the computational methods employed revealed that the small subunit 16S rRNA gene sequence from B. cereus strain UPMLH24 contained a number of small open reading frames that encoded several functional proteins. Computational predictions classified seven phyla of organisms associated with small open reading frames of novel B. cereus strain UPMLH24. The data generated from computational predictions in the present study could form the basis for further research to advance new hypotheses in the microbiology of rhizobacteria.
Phonotaxis to Amphibian Vocalizations in Culex territans (Diptera: Culicidae)

Abstract Culex territans Walker (Diptera: Culicidae) acquires bloodmeals from amphibian hosts. Females overwinter as inseminated adults and exit diapause in New Jersey when spring peepers (Pseudacris crucifer) are calling. We tested the hypothesis that Cx. territans uses amphibian vocalizations as a long-distance attractant. Two thirds of females oriented toward sound across all experiments. Females allowed to orient toward or away from a frog call, bird song, live frog, or control (a plugged in compact disc player) exhibited positive phonotaxis only to the frog call. Females exhibited positive phonotaxis to calls of P. crucifer, Hyla versicolor (northern gray tree frog), Bufo americanus (American toad), and Rana clamitans (green frog), but they were not attracted to calls of R. catesbeiana (bullfrog), R. sylvatica (wood frog), or control. Multiple regression analysis showed that call frequency is the best predictor for phonotaxis, with pulse duration and call amplitude increasing the attractiveness of the source. When exposed to P. crucifer calls at increasing sound intensity levels, females oriented to calls in the range of 50–75 dB, with particle velocities of 0.02–0.3 mm/s, indicating that phonotaxis occurs at distances >5 m from the source.
Some observations on the development of the pre-laying pullet and young hen.

Abstract While trying to estimate the nutritional requirements of pullets at the pre-laying period, it was soon realized that some basic data on their development were not available. The purpose of the present study was to evaluate changes in body weight and feed consumption starting from 30 days before the onset of egg production until one month after that time. The pattern of egg production was also followed. A group of 25 White Leghorn pullets, hatched May 19, 1970, were fed a practical pullet developer (294 Cal./100 g. of M.E., and 13.6% protein) ad libitum on an individual daily basis starting at the age of 142 days. The diet was changed to a layer ration (281 Cal./l00 g. M.E., 17.2% protein) on the day the first egg was layed. Body weight, feed intake and egg production were individually recorded. Incomplete data were obtained from the earliest and the latest layers; hence…
Structural Studies of Phosphoenolpyruvate Carboxykinase in Campylobacter jejuni

Campylobacter jejuni is an enteric pathogen which is known to be unable to metabolize glucose as carbon source unlike most of the bacteria and human due to the absence of the very important glycolytic enzyme 6-phosphofructokinase. The genome sequence of C. jejuni NCTC 11168 indicates that homologues of all the appropriate enzymes for gluconeogenesis from phosphoenolpyruvate (PEP) are present. The aim of the work described in this research article is to examine the structure of a gluconeogenic enzyme phosphoenolpyruvate carboxykinase. This was investigated by bioinformatics analysis. The sequence of PEPCK of the C. jejuni was aligned with those of E. coli and human revealing putative phosphoenolpyruvate and ATP binding site is well conserved among PEPCKs of E. coli and C. jejuni while they are quite different in human suggesting the behaviour of the human enzyme might be different as compared to E. coli and C. jejuni.
Centralized Adaptive Under Frequency Load Shedding Schemes for Smart Grid Using Synchronous Phase Measurement Unit

Under frequency load shedding (UFLS) is an effective way to prevent system blackout after a serious disturbance occurs in a power system. A novel centralized adaptive under frequency load shedding (AUFLS) scheme using the synchronous phase measurement unit (PMU) is proposed in this paper. Two main stages are consisted of in the developed technique. In the first stage, the active power deficit is estimated by using the simplest expression of the generator swing equation and static load model since the frequency, voltages and their rate of change can be obtained by means of measurements in real-time from various devices such as phase measurement units. In the second stage, the UFLS schemes are adapted to the estimated magnitude based on the presented model. The effectiveness of the proposed AUFLS scheme is investigated simulating different disturbance in IEEE 10-generator 39-bus New England test system.
Potential Predictors Of Perceived Stress In Helping Profession

The aim of this study is to explore perceived stress of an individual working in the helping profession, potential predictors and mediators of this stress. The study examines the effect of past traumatic experience, perceived mental pain, adult attachment behavior and their contribution toward present perceived stress in psychologists and social workers. A potentially preventive role of secure adult attachment and self-regulation of self-care in resulting stress perception are being explored. The methods included the use of the adult attachment behavior Experience in Close Relationships revised ECR-R (Fraley, 2000) instrument, Global Measure of Perceived stress (Cohen, Kamarck, Mermelstein, 1983), and Self-regulation of self-care (Hricová, Lovaš, in press). Other instruments used included Mental pain – Single item measure and Past traumatic experience – Single item used to measure frequency of strong negative incidents experienced before the individual started working in the helping profession. Hypotheses were tested on psychologists and social workers (n=160) using mediation models. Results suggest that a past traumatic experience predicts current mental pain perception. Professional helpers’ anxious dimension of adult attachment style partially mediates relationship between perceived mental pain and perceived stress. Avoidance dimension of adult attachment style is related to perceived stress indirectly, through self-regulation of self-care. Results of the study suggest indirect relationship between past traumatic experience and currently perceived stress. © 2017 Published by Future Academy www.FutureAcademy. org.UK
Parental Monitoring and Adolescent Adjustment: An Ecological Perspective

This study uses an ecological framework to examine the associations between parental monitoring and a variety of indicators of adolescent adjustment. Specifically, investigators examined whether higher levels of parental monitoring were associated with higher adolescent grade point average, lower levels of adolescent depression, and lower levels of adolescent sexual activity and minor delinquency, and whether these relations were moderated by gender, grade level, or mothers' work status. Participants were 424 7th to 12th graders from a single rural school district in central Pennsylvania. Bivariate correlations indicated that parental monitoring had strong associations with all indicators of adjustment for both boys and girls, with the exception of boys' depression. Gender and grade level simultaneously moderated the relation between parental monitoring and adolescent delinquency, with the effect of parental monitoring increasing across grade level for boys, and decreasing with grade level for girls.

Preparing students to respond: A pilot study to explore whether Mask-Ed simulation can assist students in developing clinical judgment

Clinical judgment is a key component of 'thinking like a nurse'(Tanner, 2006). This pilot project uses Mask-Ed™ simulation in conjunction with Tanners (2006) Clinical Judgment Model to explore clinical judgment in a pre-clinical workshop. Method: a cross sectional survey was conducted with third year nursing students enrolled in one unit of study. Results: The confidence of students to respond to a patient, one of the four domains of clinical judgment (Tanner, 2006) was increased. Conclusion : Mask-Ed™ when used in a pre-clinical workshop shows the potential to positively affect the student nurses ability to respond to a patient cues, a key part of patient care and the development of clinical judgment.
Dielectric elastomer based active layer for macro-scaled industrial application in roto-flexographic printing

The use of dielectric elastomer (DE) for the realisation of new generation actuators has attracted the interest of many researchers in the last ten years due to their high efficiency, a very good electromechanical coupling and large achievable strains [1-3]. Although these properties constitute a very important advantage, the industrial exploitation of such systems is hindered by the high voltages required for the actuation [4] that could potentially constitute also a risk for the operators. In this work we present a DE based active layer that can be used in different macro-scaled parts of industrial equipment for roto-flexographic printing substituting traditional mechanical devices, reducing manufacturing costs and enhancing its reliability. Moreover, the specific configuration of the system requires the driving voltage to be applied only in the mounting/dismounting step thus lowering further the operative costs without posing any threat for the workers. Starting from the industrial requirements, a complete thermo-mechanical characterisation using DSC and DMA was undertaken on acrylic elastomer films in order to investigate their behaviour under the operative frequencies and solicitations. Validation of the active layer was experimentally evaluated by manufacturing a DE actuator controlling both prestrain and nature of the complaint electrodes, and measuring the electrically induced Maxwell’s strain using a laser vibrometer to evaluate the relative displacement along the z-axis.
A Noval Wakeup Schedule Algorithm for Relay Nodes to enhance the lifetime of Sensor Network

: The appeal of acquiring ambient knowledge to build smart environment results in a discovery of new intelligent devices which have overall abilities of sensing, computation and communication. Through precocious networking protocols, these devices are interconnected to each other and form Wireless Sensor Network (WSN). Routing is gargantuan task in terms of wireless sensor network. A routing protocol for wireless sensor network is different from conspiring it for the traditional networks. Traditional wireless routing protocols do not adapt well to the dynamic wireless environment variations. Hence, these protocols trigger excessive link-level retransmissions, unthriftiness of network resources, and may even lead to system cataclysm. Opportunistic Routing, however, considers the shared wireless medium as an opportunity rather than a limitation. In fact, the key idea behind opportunistic routing is to overcome the drawback of unreliable wireless transmission by taking advantage of the broadcast nature of the wireless medium. The problem arising is of energy optimization in network and if energy is managed, lifetime for the network is enhanced. Thus, we bring the enhanced ENS_OR algorithm, the advanced version of ENS_OR which include wakeup schedule in it. The Enhanced ENS_OR satisfies both metrics manages energy as well as prolong the network lifetime also.
Toward a Comprehensive Theory of Variable Performance Differences and Differential Spaced Practice Effects Between Anticipation and Study-Test Methods

Summary Given the list design, two elusive puzzles persisted for decades: (a) negative spaced practice effects in verbal learning, and (b) inconsistent results in comparing anticipation and study-test methods. Both mysteries may be approached by investigating effects of the retention interval, consisting of two components: Types I (intercycle, rest) and II (work, intervening events) intervals. To this end, three paired-associate learning experiments using 178 male and female college students were conducted, each comparing the two methods with both massed and spaced practice. Both significant and nonsignificant superiority of the study-test method was observed with massed, as well as with spaced, practice. Relative performance differences between the methods are explainable by the retention interval hypothesis, but absolute differences cannot be so explained. By the coalescing of the retention interval hypothesis and the test trial potentiating model, a more comprehensive hybrid theory might evolve to reso.
Asymmetric price transmission modeling: the importance of model complexity and the performance of the selection criteria

Information Criteria provides an attractive basis for selecting the best model from a set of competing asymmetric price transmission models or theories. However, little is understood about the sensitivity of the model selection methods to model complexity. This study therefore fits competing asymmetric price transmission models that differ in complexity to simulated data and evaluates the ability of the model selection methods to recover the true model. The results of Monte Carlo experimentation suggest that in general BIC, CAIC and DIC were superior to AIC when the true data generating process was the standard error correction model, whereas AIC was more successful when the true model was the complex error correction model. It is also shown that the model selection methods performed better in large samples for a complex asymmetric data generating process than with a standard asymmetric data generating process. Except for complex models, AIC's performance did not make substantial gains in recovery rates as sample size increased. The research findings demonstrate the influence of model complexity in asymmetric price transmission model comparison and selection.
Wireless mobile communications at the start of the 21st century

At the start of the 21st century, the wireless mobile markets are witnessing unprecedented growth fueled by an information explosion and a technology revolution. In the radio frequency arena, the trend is to move from narrowband to wideband with a family of standards tailored to a variety of application needs. Many enabling technologies including wideband code-division multiple access, software-defined radio, intelligent antennas, and digital processing devices are greatly improving the spectral efficiency of third-generation systems. In the mobile network area, the trend is to move from traditional circuit-switched systems to packet-switched programmable networks that integrate both voice and packet services, and eventually evolve toward an all-IP network. Furthermore, accompanied by wireless mobile location technology, wireless mobile Internet is expected to revolutionize the services that can be provided to consumers in the right place and at the right time. Wireless mobile communications may not only complement the well established wireline network; it may also become a serious competitor in years to come. We review the history of the wireless mobile communications, examine the current progress in standards and technologies, and discuss possible trends for wireless mobile solutions.
Psychosocial stress among patients with type 2 diabetes: habitual physical activity as a promising moderator

Psychosocial stress is a disabling condition and is common among people with diabetes mellitus in view of the complexity of the disorder. It is however not clear if the psychosocial stress has any link with habitual physical activity, which is an important component in the care of people with diabetes. This study was conducted to investigate the likely connection between habitual physical activity and psychosocial stress among people with type 2 diabetes. A total of 193 adults with type 2 diabetes took part in this study. Psychosocial stress was assessed using the Revised Questionnaire on Stress in patients with Diabetes (QSD-R) while physical activity was assessed using the Baecke Habitual Physical Activity Questionnaire. Data were analysed using descriptive and inferential statistics at p < . 05. The mean age of the participants was 58.76 ± 14.27 years with mean duration of diagnosis being 6.41 ± 4. 51 years. With a mean score of 2.8, work activity was the main source of physical activity for the patients with the least activity index of 1.2 coming from sports participation. Hypoglycaemia and self-medication/diet were the most important sources of stress to the patients and the overall psychosocial stress was related to habitual physical activity (r = - .73, p = .002). Significantly, patients with higher physical activity index presented with lower psychosocial stress. Apart from the well-known improvement in glycaemic control, type 2 diabetes patients that participate more in physical activity may be able to reduce their psychosocial stress. Keywords: Type 2 diabetes, psychosocial stress, habitual physical activity
Children's Nutrition, School Quality, and Primary School Enrollment in the Philippines

We examine the importance of child health and nutrition, family background and the characteristics of public primary schools and teachers for enrollment in the first grade using longitudinal data on 1,251 school-age children and families, as well as the ECD (early childhood development)-related providers that serve their communities collected from three regions in the Philippines. The first research question relates to the associations between children’s health and nutrition at pre-school age (height for age z scores and hemoglobin levels) and enrollment in the first grade, and whether these associations are robust to standard corrections for the possibility that child health and nutrition represent, in part, omitted variables. Second, we examine the effect of multiple dimensions of school and teacher quality on enrollment with particular attention to whether there are important interactions between family background (mother’s schooling, father’s schooling) and the accessibility and quality of primary schools and teachers in their associations with enrollment. In a similar vein, we consider whether the importance of children’s health and nutrition for enrollment in school is greater in communities where families have access to better schools. Our major findings indicate that 1) children’s hemoglobin levels have significant and positive effects on school enrollment that are understated in models that take child health and nutrition as pre-determined and 2) there are important interactions between family background on the one hand and the quality and accessibility of schools on the other that suggest important complementarities in their effect on grade 1 enrollment. We do not find important interactions between children’s nutrition and the quality of schools and teachers in their relationship with enrollment. The findings suggest the importance of accounting for omitted variables when making inferences about the role of child health and nutrition or schools and teachers for schooling.

How do the Foreign-Born Rate Host Country Health Systems? Evidence from Ireland

This article evaluates how foreign-born residents perceive the Irish health system compared to the Irish-born. Using data from the European Social Survey (2002-2012), the article finds that the foreign-born are more positive than the native-born regarding the Irish health system. This positive attitude is most pronounced in the first years after their arrival and decreases with time spent in Ireland. However, perceptions vary according to the country of origin: Polish migrants are much more positive about the Irish health system than the Irish, while British-born residents rate the system just slightly more positively than Irish natives.
Commercial Evaluation of a Continuous Micronutrient Fortification Process for Nixtamal Tortillas

ABSTRACT The corn tortilla plays an integral role in the Mexican diet and is an ideal vehicle for micronutrient fortification. Approximately 60% of corn tortillas in Mexico are produced from nixtamal, with the remainder prepared from masa flour. A process for continuous fortification of nixtamal tortillas was evaluated in two commercial mills in Mexico. A commercial powder dosifier was used to add micronutrient premix containing iron, zinc, folic acid, niacin, riboflavin, and thiamin to nixtamal (1 g/kg) as it was milled. After training and preliminary sampling, mills produced fortified tortillas unassisted for four weeks. Masa flow rates over a four-day period were 10–12 kg/min in both plants. Premix flow from the dosifier showed good stability, with an average coefficient of variation of 1.6%. Initial results indicated consistency in the fortification process, with significantly increased variation during the four-week production period. Fortified tortillas had significantly higher levels of all nutrien.
