Enhancement of lifetime in Er-doped silica optical fiber by doping Yb ions via atomic layer deposition

In this study, the influence of ytterbium ions (Yb3+) on the fluorescence lifetime of erbium (Er)-doped silica optical fiber (EDF) is investigated. An Er/Yb co-doped fiber is fabricated by modified chemical vapor deposition (MCVD), along with the atomic layer deposition (ALD) method. Moreover, the spectral properties of this fiber, such as absorption, luminescence, excitation and emission spectra, and the fluorescence lifetime, are studied experimentally; the results of the experiments are then compared with those of the EDF. The results revealed the existence of a broadband luminescence spectrum at 800-1300 nm. The fluorescence lifetime of the Er/Yb co-doped fiber at 1531 nm is 11.77 ms, whereas that of the EDF is 10.16 ms. The lifetime of Yb3+ is 415 µs, which is 565 µs less than that of the Yb-doped fiber (980 µs), at 1033 nm. Simultaneously, various models of the Er-doped, Yb-doped, and Er/Yb co-doped fibers in three membered ring (3MR) structures were built, and their excited states were analyzed. The results indicated that an energy transfer is associated with the change in lifetime, and that the doping of Yb3+ significantly improves the fluorescence lifetime of Er3+ at 1533 nm.
Are Depot Anti-psychotics Associated with Longer Persistence in Treatment Compared with Oral Antipsychotics among Patients with Schizophrenia?

Aim: Non-adherence with antipsychotics is associated with poor outcomes in patients with schizophrenia. It was anticipated that drop-out from treatment due to non-compliance with oral antipsychotics could be abated with the use of depot antipsychotics. However previous studies are divergent regarding the association between persistence in treatment and the use of depot antipsychotics. This study aimed to compare treatment persistence among out-patients with schizophrenia receiving depot versus oral antipsychotics in Lagos, Nigeria. Methodology: Relevant clinical data of out-patients with schizophrenia (n=160) were retrieved one year post-hospitalisation at a public psychiatric facility in Nigeria. Treatment persistence (time to all cause treatment discontinuation) among the cohort of patients was determined using the KaplanMeier Survival analyses. Persistence in treatment between patients receiving depot versus oral antipsychotic medications alone was compared using the log rank test. Results: Nearly half (49.1%) of the cohort dropped out of treatment within one month of discharge, while 18.2% persisted for one year. There was no significant difference (p=0.727) in the mean duration of treatment persistence between patients receiving depot antipsychotics (17.4(±2.4) weeks), and those receiving oral medications alone (19.4 (±2.2) weeks). Original Research Article Adeosun; JPRI, 18(3): 1-8, 2017; Article no.JPRI. 35581 2 Conclusion: There is a high rate of drop-out from treatment among patients with schizophrenia, after discharge from in-patient care. Prescription of depot medications was not associated with longer persistence treatment in the studied cohort. This finding highlights the need to develop interventions to facilitate treatment persistence among patients with schizophrenia.
Real-time pollen monitoring using digital holography

Abstract. We present the first validation of the Swisens Poleno, currently the only operational automatic pollen monitoring system based on digital holography. The device provides in-flight images of all coarse aerosols, and here we develop a two-step classification algorithm that uses these images to identify a range of pollen taxa. Deterministic criteria based on the shape of the particle are applied to initially distinguish between intact pollen grains and other coarse particulate matter. This first level of discrimination identifies pollen with an accuracy of 96 %. Thereafter, individual pollen taxa are recognized using supervised learning techniques. The algorithm is trained using data obtained by inserting known pollen types into the device, and out of eight pollen taxa six can be identified with an accuracy of above 90 %. In addition to the ability to correctly identify aerosols, an automatic pollen monitoring system needs to be able to correctly determine particle concentrations. To further verify the device, controlled chamber experiments using polystyrene latex beads were performed. This provided reference aerosols with traceable particle size and number concentrations in order to ensure particle size and sampling volume were correctly characterized.
Experience of a Single Center in Treating Multiple Manifestations of Tuberous Sclerosis Complex with Everolimus

mammalian target of rapamycin (mTOR) inhibitor, for the treatment of tuberous sclerosis complex (TSC) manifestations. Methods: A retrospective analysis was conducted using an in-house research database with the keywords “tuberous sclerosis AND everolimus. ” Twenty patients were treated with everolimus for TSC from 2013 to February 2019. Results: The mean age of the 20 patients was 25.6 years (range, 0 to 57), and the average duration of everolimus treatment was 87.6 weeks (range, 0 to 290). Everolimus was given with a usual daily dosage of 5 to 10 mg (mean, 7.1) or 0.0625 to 0.5 mg for neonates. Twelve patients were prescribed everolimus for more than 1 year for kidney angiomyolipoma (AML). Two of those patients (16.7%) experienced reductions of >50% in tumor size, and four patients (33.3%) experienced reductions of 25% to 50%. The four patients who were prescribed everolimus for subependymal giant cell astrocytoma (SEGA) had 25% to 50% reductions. Neonates with cardiac rhabdomyoma showed significant tumor reduction with everolimus, but their tumors exhibited rebound size increases after treatment was halted. Of the three patients with intractable seizures, one patient became seizure-free, and two patients had >50% reductions. Overall, everolimus therapy was well tolerated. Conclusion: Everolimus, an mTOR inhibitor, was effective for seizure control and size reduction of kidney AML, SEGA, and cardiac rhabdomyoma tumors in patients with TSC. However, clinicians should also be aware of the adverse event profile of everolimus.
A two-dimensional analytical model of PEMFC with dead-ended anode

ABSTRACT When the proton exchange membrane fuel cell (PEMFC) works in the mode of dead-ended anode (DA), the water and the nitrogen in the cathode flow channel will diffuse, and accumulate, to the anode flow channel resulting in fuel starvation on the anode side as well as the performance degradation of PEMFC, which has an important impact on the durability and working state of PEMFC. Because the PEMFC performance is closely related to the cathode working parameters, in order to study the influence of the cathode working parameters on the performance of the PEMFC with DA, a two-dimensional analytical model of PEMFC with DA is established in this article, and the parameters in the model are corrected by experiments. The effects of humidity, stoichiometric ratio and working pressure of cathode gas on the performance of PEMFC with DA are studied by model and experiment, as well as the effects of these working parameters on the accumulation process and distribution of water vapor and nitrogen on the anode side, and the relative performance of PEMFC with DA under different cathode working parameters is obtained. This model is of great significance to guide the practical work of the PEMFC with DA.
Are employees well evaluated in their CSR actions? The perception of managers in an emerging country

Purpose – This paper tests the influence of employees’ involvement in CSR activities on manager s’ perception s regarding business confidence. Design/methodology/approach – A quantitative methodology was used to contrast the hypotheses presented in this paper. The empirical research began in March 2016. In April 2016, a questionnaire was sent by email to the 1,745 managers of the multiple banks with a message explaining the relevance of the research. The data gathering process finished in July 2016. Findings – The causal model proved the influence of the perception of employees’ involvement in the CSR actions of Peruvian banks in terms of improving the perception of business confidence by managers. The relationship found was not statistically significant at a level of p<0.05. Therefore, the assessment of the involvement of workers in CSR in Peruvian banks does not significantly influence business confidence. Originality/value – The main contribution of this paper is that it empirically analyzes how business confidence is perceived by managers and how it is influenced by perception s of employees’ involvement in CSR actions in a context barely investigated : an emerging country.

Purpose : The purpose of this study was to investigate the causal relationship between parenting styles and academic self-handicapping by mediating role of meta-cognitive and perfectionism skills. Methodology : The statistical population of the study consisted of all the second grade secondary school students in studying the academic year of 2017-18, in Bojnourd. A sample of 350 students was selected using multi-stage cluster sampling. To collect the data,(a) Alabama Parenting Questionnaire (APQ),(b) Metacognitive Skills Questionnaire(MCSQ)(Dowson,Mcinerney, 2004), (c) Perfectionism Scale (Hewitt, Flett (1991) and (d) Academic self-handicapping Scale (ASHS) (Schwinger, 2014) were used. Pearson correlation coefficient and Structure Equation Modeling were used to analyze the data. Findings : Findings showed that parenting styles directly to academic self-handicapping was not significant, But through the mediating role of meta-cognitive skills and perfectionism was significant. and the hypothetical model had good fit. Conclusion : teaching of the metacognitive skills to students will reduce the academic self-handicapping, and the increaseing of perfectionism will increase the likelihood of academic self-handicapping in the students.
Factors Affecting Birth Weight in Sirohi Goat Kids

The goat “Movable Wealth” for nomads, small and marginal farmers and land less labours has tremendous potential to be projected as the „Animal of Future‟ for rural prosperity. The agro-geo-climatic conditions are changing and resources depleting continuously for crop-based livelihood. In India, we have 23 well defined goat breeds. India possesses the second-largest goat population in the world having 135.17 million goats, but their population has declined by 3.82% over the previous census (Anonymous, 2012). Goat farming plays an important role in the up liftment of rural economy and livelihood which is creates employment of rural youth. This is because goats can thrive in hardy weather conditions and can be conveniently reared on uncultivable land where dairy farming is not economical. Sirohi is a dual purpose breed of goat native of central and southern regions of Rajasthan. These goats breed have a high resistance to disease and adapt well to hot, dry deserts areas. Birth weight is an economic indicator for any livestock production purpose. There is a positive correlation in birth weight and further increasing of the live weight of animals (Roy et al., 1989). Studies of various authors show that birth weight is influenced by sex, type of birth, season of birth, maternal age and more (Supakorn and Pralomkarn, 2009; Bharathidhasan et al., 2009).

Assessment of genetic diversity in sorghum bicolor using RAPD markers

Sorghum is one of the most important cereal crop and ranks fifth among cereals after wheat, rice, maize and barley for economic importance. Because the demand of food is increasing, sorghum will increase in importance as a source of food, feed, fibre, and fuel; specially in the European continent where sorghum is little cultivated, mainly due to the lack of sorghum varieties well adapted to the soil and climate conditions such as photoperiod, cold and drought; for this reason, the genetic diversity analysis, through molecular characterization, is an important requirement to begin a plant breeding program. The analysis was performed in 46 sorghum genotypes obtained from the Czech Plant Gene Bank, Crop Research Institute, Prague. Genetic variability values were estimated, through the genetic distance using Dice’s coefficient, and dendrogram constructed using DARwing software. Four out of fifteen of the primers evaluated were completely polymorphic (100%), A hundred and twenty-six scorable bands were identified and 89% of them were polymorphic, the bands ranged from 200 to 2000 bp. The dendrogram grouped the accession into six clusters. The results indicate the existence of high genetic distance values up to 0.8776 among the evaluated accessions, even if the accessions were collected in the same country, or by the contrary, lower genetic diversity among accessions collected in different countries. It may be due to the existence of five ancient races of sorghum, from which were originated most of the wild and cultivated species known nowadays. Mainly, the migration of people from the origin centre of sorghum, located in Ethiopia and Sudan, explain the spread of the genetic material out of Africa. The information generated by this study should be useful for a better understanding of the genetic diversity from the sorghum germplasm stored in the Czech Plant Gene Bank for future plant breeding program.
A Comparative Study of Glucose Levels in Blood and Saliva of Type 2 Diabetic Patients of Balkot

Background and objective: The increasing trend in prevalence of diabetes mellitus around the world is alarming. Glucose levels in diabetic patients should be regularly monitored to minimize the diabetic complications. The purpose of the present study was to study the correlation between salivary and blood glucose levels. Awareness and knowledge about diabetes and perception on blood glucose maintenance among study population was also assessed. If a close correlation were to exist, diabetic control could be monitoed by the noninvasive method of measuring salivary glucose. Methods: Age matched 50 diabetic and 50 healthy non-diabetic individuals were included in the study. Structured questionnaire was used to know the educational status and knowledge about diabetes mellitus. Estimation of serum and salivary glucose levels in fasting state were carried out by Glucose Oxidase Peroxidase (GOD-POD) method, using semi-automated machine. Results: Higher percentage of diabetic patients had good knowledge and perception about diabetes and blood glucose maintenance than healthy subjects. Among diabetics mean salivary glucose level was 9.98±3.01 mg/dl. This was much higher as compared to non-diabetic individuals (7.56±1.37 mg/dl). Mean salivary glucose levels were found to be significantly correlated with mean blood glucose levels of diabetics (r= 0.811) and non diabetics (r= 0.506). Conclusion: This study suggested that saliva may become an alternative to blood for lab diagnostic procedures if further extensive studies are done in future.
Determinants of utilization of antenatal and postnatal care services in Telangana

Background: Variation exists in utilization of antenatal and postnatal care services in public health facilities of developing countries. Provision of antenatal and postnatal care services is the major function of public health delivery system of India to improve maternal health outcomes. The objective of this study is to estimate the determinants of utilization of antenatal and postnatal care services stratified by geographical region in Telangana. Methods: It is a cross-sectional study of District Level Health and Facility Survey-4 of the state of Telangana. Multistage, stratified, probability proportional to size sample with replacement was used. 3065 women, who delivered after the year 2008, were considered for analysis. Descriptive analysis of components of antenatal and postnatal care services stratified by geographical region was carried out. Binomial logistic regression was carried out to determine association of demographic, system level variables with adequate antenatal care. Results: Study reveals variation exists across four regions of Telangana in utilization of maternal health services. Reception of adequate antenatal care is low in South region (20.6%) and high in East region (31.5%). Pregnant women with secondary education were 66% more likely to receive adequate antenatal care services compared to illiterate. Conclusions: Short term and long-term goals to be adopted and implemented by government to address the demandsupply imbalance such as public health infrastructure and quality of services in underperforming districts of Telangana to increase utilization of maternal health services by training health staff and engaging local communities to seek health care services.
Assessment of prevalence, knowledge, attitude and practices of obesity among college students in Sohag Governorate

Introduction: The WHO classifies about 400 million people around the world as obese. Obesity is the fifth leading cause for deaths all over the world. The prevalence of obesity has nearly doubled between 1980 and 2008. The aims of this study were to: estimate the prevalence of obesity, study the KAP (knowledge, attitude and practice) among students studying at Sohag University and compare KAP between obese and non obese participants. Subjects and Methods: A cross sectional study. This study was based on interviewing university students in the period from January 2015 to December 2015. A total of 961 students were included. A specially designed questionnaire was applied for all of the participants by KAP Model designed by Librahim in 1995. Results: Our study included 961 university students, mean age 19.5±1.5 years; equally divided into males and females. The prevalence of obesity among our study group was 17.2%. No significant difference between obese and non obese students regarding age or sex. Diagnosis:36.4% of them were by medical consultation, 29.1% by self notice, 18.8% by family and lastly 15.8% by other methods. The knowledge about obesity was assessed by two types of questions; the nature of obesity and its cause the vast majority of our participants thought that obesity is a hormonal disease, then psychological and an infectious disease. As the attitude, surprisingly, more of the obese persons thought that they should not marry or have children than the non obese ones, only about half of our obese persons thought that they can think like any normal person, compared to over 76% of the non obese persons had this belief; the difference is significant. As regards the practice towards obesity, less than half of the obese persons agreed to marry another obese one, while only 28% of the non obese persons agreed to do. We found that more of the non obese persons agreed to have friendship and/or to work with an obese person (53%) compared to only (37%) of the obese persons. The differences in the above three comparisons were statistically significant. Conclusion: Obesity is a common and problematic health condition among Sohag University students. More effort should be done to improve the knowledge and attitude towards obesity.
Short Communication - Antimicrobial susceptibility of some urinary tract clinical isolates to commonly used antibiotics

The antimicrobial susceptibility of urinary tract isolates from pregnant women attending antenatal clinics in various hospitals within Kaduna, Nigeria, was carried out using the disc diffusion method. The patterns of inhibition varied with the concentration of the antibiotic used. Escherichia coli was the most sensitive to ciprofloxacillin (33 mm/5 μg ml -1 ) and pefloxacin (15 mm/10 μg ml -1 ). It was resistant to minocycline, nalidixic acid, cefuroxine and cotrimoxazole. Klebsiella spp. , Proteus spp. and S taphylococcus spp. were moderately sensitive to ciprofloxacillin (14, 15 and 18 mm/5 μg ml -1 ) respectively. All the organisms were resistant to minocycline and cefuroxine. Ciprofloxacillin appeared to be the drug of choice for the treatment of urinary tract infection. Keywords: Urinary tract infection, clinical isolates, antibiotics
Temporality and social movements: a political ethnography of activism in contemporary Turkey (2016-2018)

While social movement studies have developed extensive frameworks for studying the emergence, maintenance, and decline of social movements, temporal orientations and futurity have not been systematically mobilized as necessary explanatory dimensions of activism. This dissertation argues that activists' temporal orientations and future imaginings are crucial to understanding action, including organizational form, movement trajectories, and long-term projects. Futurity is particularly relevant and amenable to theorization in uncertain, politically volatile, and urgent times, when activist debates revolve around predictions, expectations, possibilities, and scenarios. I take grassroots activism in Istanbul, Turkey between 2016 and 2018 as a case in point to examine the changing dynamics of activism during regime change. Based on participant-observation at a local assembly that was established to campaign for the “no” vote in the constitutional referendum of 2017 supported by semi-structured, in-depth interviews with activists, this study follows the changes in activists' temporal orientations and their relationship to different aspects of activism. The dissertation begins with an examination of the organizational structure of the local “no” assembly as a product of activists' critical engagement with the past and the future, by looking at their re-reading of the Gezi protests of 2013. The analysis then moves on to the period around the 2017 referendum, when future imaginings, in the form of anticipatory scenarios about the near future, played a constitutive role in the decision-making processes of the assembly, and contending futures resulted in its disintegration. Lastly, as the referendum was left behind and as activists were faced with defeat at the 2018 presidential and general elections, their engagement with the distant future came to the fore, in the form of hope, which enabled and was enabled by a future-oriented narrative of historical embeddedness. To conclude, I argue that scholars of social movements should pay more attention to the role of possibilities and future imaginings in political action, as well as the open-endedness inherent in activism, especially at times marked by uncertainty and urgency.
Could the North Pacific Oscillation Be Modified by the Initiation of the East Asian Winter Monsoon?

This study investigates the modulation of North Pacific Oscillation (NPO) variability upon initiation of the East Asian winter monsoon (EAWM). The data show that the initiation of EAWM in the Philippine Sea strongly connects to the southern lobe variability of the NPO in January followed by a basin-scale oceanic Victoria mode pattern. No apparent connection was found for the northern lobe of the NPO when the ENSO signals are removed. The strengthening of the EAWM in November interacts with the Kuroshio front and generates a low-level heating source in the Philippine Sea. Significant Rossby wave sources are then formed in the lower to midtroposphere. Wave ray tracing analyses confirm the atmospheric teleconnection established by the Rossby wave propagation in the mid- to upper troposphere. Analyses of the origin of wave trajectories from the Philippine Sea show a clear eastward propagating pathway that affects the southern lobe of the NPO from the southern lobe of the western Pacific pattern at 500 hPa and above on the time scale of 20 days. No ray trajectories from the lower troposphere can propagate eastward to influence the central-eastern subtropical Pacific. The wave propagation process is further supported by the coupled model experiments.
