A Model for Integrating ICT into Teacher Training Programs in Bangladesh Based on TPCK.

Modern technology increasingly creates new challenges in various professional development and practice. However, in teaching, the mere adoption of new or innovative technology is not enough to meet the students’ learning needs and opportunities. Technology alone could not sufficiently bring about the desired changes in students’ competencies and behavior. It is the teachers’ competencies to integrate ICT in their instructional tasks that can facilitate these desired changes to the maximum level. Therefore, there is an increasing demand for the inclusion of pedagogy and substantial content knowledge based use of ICT in teachers’ professional development. In this paper, the author presents a model for integrating ICT in the professional development of teachers in Bangladesh based on the Technology Pedagogy Content Knowledge (TPCK) framework, to address the issue on effective use of ICT in teaching based on two perspectives. Firstly, how the teachers can undertake three different phases of improving their use of technology to facilitate effective instruction. This will be focused on understanding the challenges in the use of ICT in three phases of teachers’ professional development in Bangladesh, particularly the pedagogical and contextual (specific subject content) issues concerning prerequisite conditions that ensure the effective use of ICT. Secondly, the paper highlights on conclusive suggestions to implement the proposed model demonstrating the potential benefits to the teachers, trainers, policymakers and other educators who are directly or indirectly accountable for teachers’ professional development. Finally it concludes with emerging research issues and pertinent guidelines in the context of Bangladesh.
Growth and life history traits of a highly exploited population of non-native gibel carp, Carassius gibelio from a large eutrophic lake (Lake Uluabat, NW Turkey): is reproduction the key factor for establishment success?

To assess establishment success of a heavily exploited population of non-native gibel carp Carassius gibelio, biological traits and population structure of the species from a large eutrophic lake (Lake Uluabat, Turkey) were investigated from June 2009 to May 2010 and attributes were compared with the published information from the introduced and native range. Commercial harvesting of gibel carp did not seem to affect population size and viability of gibel carp in Lake Uluabat but it had one of the slowest growth rate represented by twelve age groups, and its life span was one of the longest recorded for the populations both in its natural and introduced areas. The reproductive season lasted from March to early May. Size at maturity was earlier and relative fecundity was higher than those in the introduced range. Higher investment in reproduction displayed by earlier maturation, higher relative fecundity and gonadosomatic index with gynogenetic spawning in Lake Uluabat is likely to be the key factor for establishment success of gibel carp.

The paper presents the influence of shaker cultivation conditions on the growth and torularhodin formation of the yeast Rhodotorula rubra ICCF 209 and the procedure for the extraction, separation, and quantitative determination of the carotenoids, mainly beta-carotene and torularhodin, with antioxidant potential characteristics.
Comparative study between semi-intensive and scavenging production system on the performances of Black Bengal goat

The experiment was aimed to investigate and compare the growth, milk production and reproductive performances of Black Bengal goat under semi-intensive production (IP) and scavenging production (SP) system. Six Black Bengal does were assigned into 2 treatment (IP and SP) having 3 in each group. The IP group was allowed to graze six hours daily and supplemented with concentrate (soybean meal and wheat bran) and roughage (sorghum and common grass) and the SP group was maintained by the rural landless farmer traditionally as scavenging system. The average birth weight of kids were 1.30 and 0.96 kg for IP and SP systems, respectively and varied significantly (P<0.01). The birth weight of male kids were significantly (P<0.01) higher than that of the female kids. Pre-weaning gain was also significantly (P<0.01) higher in IP than sp system. In both the systems, male kids always showed higher gain than that of females. The kids were weaned at an average age of 92 and 81 days for IP and SP systems, respectively. The kids of the IP and SP systems attained at an average weaning weight of 5.43 and 4.17 kg, respectively which differs significantly (P<0.01). Weaning weight was found to be significantly higher in IP than SP systems. Average initial live weight, live weight at kidding and final live weight at post partum heat of does of IP and SP systems were 22.10, 22.61 and 21.03 and 21.90, 22.35 and 19.73 kg, respectively, where there was no significant difference except the final live weight (P<0.05). The average daily milk yield, total lactation yield and lactation length for IP and SP systems were 214 ml, 20.47 l and 95.33 days and 162 ml, 13.75 l and 84.66 days, respectively and varied significantly (P<0.01). Average litter size of the IP and SP systems was 2.00 and 2.33, respectively. Average post partum heat period and kid mortality were significantly (P<0.01) lower in IP than SP system. Gross return was found higher in IP than that of SP systems. Thus, it can be recommended from the present study that the growth rate, weaning age, weaning weight, milk production, post partum heat period and kid mortality of Black Bengal goat could be improved through proper feeding and better husbandry system which was reflected from gross return.
The Gaia-ESO Survey: Dynamical Analysis of the L1688 region in Ophiuchus

The Gaia ESO Public Spectroscopic Survey (GES) is providing the astronomical community with high-precision measurements of many stellar parameters including radial velocities (RVs) of stars belonging to several young clusters and star-forming regions. One of the main goals of the young cluster observations is to study of their dynamical evolution and provide insight into their future, revealing if they will eventually disperse to populate the field, rather than evolve into bound open clusters. In this paper we report the analysis of the dynamical state of L1688 in the $\rho$~Ophiuchi molecular cloud using the dataset provided by the GES consortium. We performed the membership selection of the more than 300 objects observed. Using the presence of the lithium absorption and the location in the Hertzspung-Russell diagram, we identify 45 already known members and two new association members. We provide accurate RVs for all 47 confirmed members.A dynamical analysis, after accounting for unresolved binaries and errors, shows that the stellar surface population of L1688 has a velocity dispersion $\sigma \sim$1.14$\pm$0.35 km s$^{-1}$ that is consistent with being in virial equilibrium and is bound with a $\sim$80% probability. We also find a velocity gradient in the stellar surface population of $\sim$1.0 km s$^{-1}$pc$^{-1}$ in the northwest/southeast direction, which is consistent with that found for the pre-stellar dense cores, and we discuss the possibility of sequential and triggered star formation in L1688.
Estimation of a Labour Supply Model with Censoring Due to Unemployment and Underemployment

This study proposes and implements a method of labour supply estimation which is appropriate when the sample contains unemployed and underemployed workers. The estimation method consists of excluding unemployed and underemployed workers from the sample and then using (to avoid selection bias) an extension of Heckman's approach to the case where two correlated selection rules generate the sample. Hausman's specification test is then used to determine whether ignoring constrained workers has led to biases in traditional labour supply estimates, and the empirical results suggest that previous estimates of several important parameters are biased. Since the biases go in the direction that would be predicted by the hypothesis that the unemployed and underemployed are constrained, the results support this hypothesis.
A Study on Smartphone Addiction, Mental health and Impulsiveness For High School Students at Korea

The purpose of this study is to verify the causal relationship between the smartphone addiction proneness, mental health, and impulsiveness of high school students in Korea. 804 first and second year high school students participated in the survey that included the Smartphone addiction scale, Korean Brief Mental Diagnosis Exam the highest 25% of total score (Addictive SmartPhone Use Group : ASPUG 213 persons), the lowest 25% of total score(Non-Addictive SmartPhone Use Group : NASPUG 204 persons), BIS-II Impulsiveness Scale and additional questions asking for demographical characteristics.

First, sex, grade of high school, academic accomplishment, student's satisfaction with school life, monthly allowance, the level of parental respect, having a opposite sex friend were related to smartphone addiction and impulsiveness. Second, ASPUG had worse mental health and impulsiveness than NASPUG, and the difference was statistically significant. Third, Students showed higher levels of mental health 9 subareas anxiety, depression, phobic anxiety, Somatization, obsessive compulsive, interpersonal sensitivity, hostility, Paranoid ideation, Psychosis as their smartphone use increased.
Optimal linear estimation for systems with transmission delays and packet dropouts

This study considers a networked system in which the measurement suffers from one-step delay and packet dropouts because of the unreliability of the network. A new model applied to describe the arrival conditions of the measurements is proposed. Based on the new model and using a state augmentation method, optimal linear filter, predictor and smoother are obtained. A sufficient condition for the convergence of the system is given. Finally, the simulation results show the effectiveness of the proposed algorithms.
Holographic field theory models of dark energy in interaction with dark matter

We discuss two lagrangian interacting dark energy models in the context of the holographic principle. The potentials of the interacting fields are constructed. The models are compared with CMB distance information, baryonic acoustic oscilations, lookback time and the Constitution supernovae sample. For both models the results are consistent with a non vanishing interaction between dark sectors - with more than three standard deviations of confidence for one of them. Moreover, in both cases, the sign of coupling is consistent with dark energy decaying into dark matter, alleviating the coincidence problem.
Levodopa‐induced dyskinesia in Parkinson disease: Sleep matters

The spectrum of clinical symptom changes during the course of Parkinson disease (PD). Levodopa therapy, while offering remarkable control of classical motor symptoms, causes abnormal involuntary movements as the disease progresses. This levodopa‐induced dyskinesia (LID) has been associated with abnormal cortical plasticity. Because slow wave activity (SWA) of nonrapid eye movement (NREM) sleep underlies adjustment of cortical excitability, we sought to elucidate the relationship between this physiological process and LID.
Empagliflozin directly improves diastolic function in human heart failure

Empagliflozin, a clinically used oral antidiabetic drug that inhibits the sodium‐dependent glucose co‐transporter 2, has recently been evaluated for its cardiovascular safety. Surprisingly, empagliflozin reduced mortality and hospitalization for heart failure (HF) compared to placebo. However, the underlying mechanisms remain unclear. Therefore, our study aims to investigate whether empagliflozin may cause direct pleiotropic effects on the myocardium.
COMPARATIVE STUDY OF GENITAL TUBERCULOSIS DIAGNOSIS IN WOMEN WITH INFERTILITY

BackgroundGenital tuberculosis (GTB) is one of the important factors that cause infertility in women. GTB is mostly asymptomatic in nature and infertility generates high suspicion for GTB in reproductive age. The object of this study was to compare the different methods to diagnose GTB in Infertile patients. Material and methodWomen patients seeking diagnosis of infertility in the OPD of Obstetrics & Gynecology department during April 2016 to March2017 were included in this study. A total of 62 endometrial samples were processed by AFB smear microscopy, L-J culture, BACTEC culture and Genexpert to diagnose the tuberculosis. ResultsOut of 62 patients with infertility suspected of GTB, 26 were found to be positive either by AFB smear, L-J culture, BACTEC culture and Genexpert. Only one sample was found to be positive by all methods. Fourteen samples to be found positive with both L-J culture and BACTEC culture methods. ConclusionThe study indicated that the old method of AFB smear is less sensitive when compared with the L-J culture and BACTEC culture. Although Genexpert have a high specicity and sensitivity but still there are limitations in the diagnosis of endometrial biopsy samples. This study suggest both liquid and solid culture have an important role in the diagnosis of genital tuberculosis.
Wind Loading on Solar Panels at Different Inclination Angles

In the c urrent study, CFD simulations were carried out to estimate the wind loads for various wind directions on stand-alone and arrayed solar panels . Simulations were carried o ut for Reynolds number (Re) equal to 6 10 2￻×atdifferentazimuthal ( ﷿q)and inclination(﷿j)angles.For the stand-alone cases,the bottompanels in an array were criticalin terms of wind loading . Another investigation was performed to determine themaximum sheltering effect of one set of panels on another set. It was observed that at a specific distance between two sets of panels the drag coefficient for thedownstream sets of panels reaches a minimum.
Pivotal role of sea ice sediments in the seasonal development of near-shore Arctic fast ice biota

The impact of sea ice sediments on the seasonal development of sea ice biota was assessed in Alaskan nearshore fast ice. Ice, water, and seafloor sediment were sampled in spring 2002 and 2003 at 2 locations. Light in the sediment-loaded sea ice location (total particle load = 106 g dry mass, DM, m -2 ) was reduced by more than 99% compared to the clean ice location (total particle load = 6 g DM m -2 ). Strong bottom ice algal blooms developed in sediment-free fast ice, reaching their maximum of 330 µg chl a l -1 (36 mg chl a m -2 ) in late May. Pigment levels in sediment-laden ice never exceeded 9 µg chl a l -1 (1 mg chl a m -2 ). In the water column, pigment levels remained below 1 µg chl a l -1 (<5 mg chl a m -2 ) under both clean and sediment-laden ice. With increasing ice algal biomass, the δ 13 C ratio of sea ice particulate organic matter (POM) in clean ice increased from -25‰ in February to -16‰ in May, while no and little enrichment was observed in sediment-laden ice and pelagic POM, respectively. The abundance of ice metazoans in clean ice increased with progressing season from 17 700 (Feb) to 276 200 ind. m -2 (May), dominated by nematodes and ice-associated poly- chaete juveniles. In sediment-laden ice, maximum abundance was 16 600 ind. m -2 (May). Abun- dances of meroplanktic polychaete juveniles were at least one order of magnitude below abundances in the ice, suggesting sea ice is an important feeding habitat for these young life stages. Sediment within the ice had a profound impact on sea ice biota, and delayed or inhibited the spring bloom development.
THE RELATIONSHIP OF SECTOR CHARACTERISTICS TO OPERATIONAL ERRORS.

Abstract : An exploratory study was conducted on the relationship of air traffic control (ATC) complexity factors to operational errors (OEs). This consisted of a detailed examination of OE data from 1992 through 1995 from the Atlanta en route center. The Systematic Air Traffic Operations Research Initiative (SATORI) system was used to collect data for the analysis. Sectors were categorized into zero-, low-, and high-error groups. Fifteen sector and traffic flow variables had statistically significant correlations with OE frequency. Four variables were higher for the high-error group as compared to the zero-error group. Sector size was smaller for the high-error group as compared to the combined zero- and low-error categories. A significant multiple correlation was found between overall OE rate and a subset of the ATC complexity measures. The data were also analyzed to define relationships between the complexity measures and controller situational awareness (SA) at the time of the OE. The only statistically significant difference between OEs with and without SA was for horizontal separation. In addition, high-error sectors were characterized by low SA for errors. Certain sector and traffic flow characteristics were associated with these high-error sectors, suggesting that these factors may negatively affect SA. It was concluded that the results demonstrated a relationship between sector complexity and OE rate. Such findings, if extended, could assist with traffic management, sector design activities, and the development of decision-support systems.
Dynamical and Microphysical Retrieval from Doppler Radar Observations Using a Cloud Model and Its Adjoint. Part I: Model Development and Simulated Data Experiments.

Abstract The purpose of the research reported in this paper is to develop a variational data analysis system that can be used to assimilate data from one or more Doppler radars. In the first part of this two-part study, the technique used in this analysis system is described and tested using data from a simulated warm rain convective storm. The analysis system applies the 4D variational data assimilation technique to a cloud-scale model with a warm rain parameterization scheme. The 3D wind, thermodynamical, and microphysical fields are determined by minimizing a cost function, defined by the difference between both radar observed radial velocities and reflectivities (or rainwater mixing ratio) and their model predictions. The adjoint of the numerical model is used to provide the sensitivity of the cost function with respect to the control variables. Experiments using data from a simulated convective storm demonstrated that the variational analysis system is able to retrieve the detailed structure of wind,.
Association of KIR Genotypes and Haplotypes in HBeAg-positive Chronic Hepatitis B Patients Treated with Entecavir

ABSTRACT Background:A large proportion of patients with chronic hepatitis B (CHB) in China do not respond to entecavir (ETV) treatment. It remains unclear whether the Killer immunoglobulin-like receptor (KIR) genotypes and haplotypes were associated with the advantage of seroconversion in phepatitis B e-Antigen (HBeAg) positive CHB patients treated with ETV. Methods: Polymerase chain reaction with sequence-speciﬁc primers (PCR-SSP) was used to analyze KIR genes in a Chinese Han population of 198 ETV-treated HBeAg-positive CHB patients and 200 healthy controls. Of the 198 patients, 59 were complete response group (CRG) and 139 were null or partial response group (NPRG) to the treatment with ETV. Results: The frequencies of KIR genotype M, and haplotype 8 were significantly higher(P = 0.017, OR = 2.497，95%CI = 5.39–1.16 and P = 0.034, OR = 1.905，95%CI = 3.48–1.04, respectively), while the frequencies of genotype AH and haplotype 5 were significantly lower (P = 0.039, OR = 0.504, 95%CI = 0.97–0.26 and P = 0.031, OR = 0.601, 95%CI = 0.96–0.38, respectively) in HBeAg-positive CHB patient group than those in healthy group. Of note, the frequencies of KIR genotype AF and haplotype 1 were significantly higher (P = 0.022, OR = 2.860, 95%CI = 7.24–1.13 and P = 0.001, OR = 3.261, 95%CI = 6.47–1.64, respectively), while the frequencies of genotype AH and haplotype 5 were significantly lower (P = 0.038, OR = 0.338, 95%CI = 0.98–0.12 and P = 0.004, OR = 0.354, 95%CI = 0.73–0.17, respectively) in NPRG than those in CRG. Conclusions: The patients with KIR genotype AF and haplotype 1 might be negative, while genotype AH and haplotype 5 might be of advantage to the therapy with ETV, which are useful for improving novel personalized precise therapy strategy in HBeAg-positive CHB patients.
High School Curriculum and Financial Outcomes: The Impact of Mandated Personal Finance and Mathematics Courses

Financial literacy and cognitive capabilities are convincingly linked to the quality of financial decision-making. Yet, there is little evidence that education intended to improve financial decision-making is successful. Using plausibly exogenous variation in exposure to state-mandated personal finance and mathematics high school courses, affecting millions of students, this paper answers the question “Can high school graduation requirements impact financial outcomes? ” The answer is yes, although not via traditional personal finance courses, which we find have no effect on financial outcomes. Instead, we find additional mathematics training leads to greater financial market participation, investment income, and better credit management, including fewer foreclosures.
Impact of Diabetes Mellitus Type 2 on Oral Health among Out Patient Department of Saveetha Dental College and Hospital

Aim:To assess the impact of diabetes mellitus type 2 on oral health. Objective: Diabetes can also affect affect overall bodily health which also includes your oral health. Therefore this study is conducted thereby to assess the oral health problems associated with diabetes mellitus type 2. Background: Diabetes affects body’s ability to utilize the glucose or blood sugar for energy. Diabetes can cause many complication. These include nerve damage, stroke, heart disease, kidney disease and even blindness. Another common health complication is gum disease and other oral disease. Methods: Thirty patients were selected from the clinic of Saveetha Dental College for this study. All patients underwent a comprehensive oral examination performed by a single dentist which included evaluation of bleeding gums, periodontitis and decayed and missing teeth. With the help of these indices, we were able to determine the oral health status of the selected 30 patients. Periodontal health status of the patients were determined with the help of GI, PDI,and PI. And the dental carries status was determined by DMFT. Collected data were analyzed with the help of SPSS software. Data were presented as numbers (n) and percentage (%). The sample were analyzed by frequency test. Result: From the statistical analysis we can interpret that the patients with T2DM (type 2 diabetes mellitus) are very much prone to oral diseases which are marked by increased periodontal disease and gingivitis and poor plaque status. Due to chronic periodontal disease, there is a progress in destruction of supporting tissue of teeth as well as pocket formation, recession or both which may lead to tooth loss because of destruction of alveolar bone. Conclusion: As a conclusion of this study, we can conclude that diabetic patients are much prone to oral disease. Periodontal disease is most commonly occurring among T2DM.This study clearly depicts that Diabetes increases the risk of periodontal disease.
