Predictors of tuberculosis recurrence in the district of Bantul PurposeThe purpose of this research was to identify associated factors of TB recurrence. MethodsThe study design was a retrospective cohort. We  used TB cases registered in Bantul regency data in 2003-2014 that consisted of 3418 patients. Sampling was conducted by non-random methods with purposive sampling based on inclusion criteria of 904 samples. The variables measured were: age, sex, drug swallowing supervisor, health service facility, socioeconomic and sputum conversion. We used the Cox proportional hazard model for data analysis to determine the rate of occurrence and timing of the occurrence of an event. ResultsMale sex (HR = 0.91; p-value = 0.17) age> 40 years (HR = 1.03; p-value = 0.59), low income (HR = 0.89; p-value = 0.11) were not predictors of TB recurrence, while hospital treatment (HR = 0.81; p-value = 0.00), no sputum conversion (HR = 0.58; p-value = 0.00), treatment failure (HR = 0.49; 95% CI: 0.37-0.64), and treatment of less than 6 months (HR = 0.008; 95% CI: 0.00-0.07) were predictors of TB recurrence. There were 56 (6.18%) of 904 patients who experienced relapse after cured or failed treatment. The average patient relapsed after 17 months of completion of the first treatment. ConclusionHealth facilities, sputum conversion, end-of-treatment status and duration of treatment are pulmonary TB recurrence factors, and as a result can be used to predict TB recurrence in the district of Bantul.

Additivity of entropic uncertainty relations
Authors: Schwonnek René
Published: March 2018

We consider the uncertainty between two pairs of local projective measurements performed on a multipartite system. We show that the optimal bound in any linear uncertainty relation, formulated in terms of the Shannon entropy, is additive. This directly implies, against naive intuition, that the minimal entropic uncertainty can always be realized by fully separable states. Hence, in contradiction to proposals by other authors, no entanglement witness can be constructed solely by comparing the attainable uncertainties of entangled and separable states. However, our result gives rise to a huge simplification for computing global uncertainty bounds as they now can be deduced from local ones. Furthermore, we provide the natural generalization of the Maassen and Uffink inequality for linear uncertainty relations with arbitrary positive coefficients.

An analytical solution to the problem of the deflection of a flat arched statically determinate truss un-der the action of a uniformly distributed and concentrated load is obtained and analyzed. To obtain the depend-ence of the deflection on the number of panels, an induction method was used in two parameters — the number of panels in the crossbar and the number of panels in the supporting side trusses. All transformations and analysis are performed in the system of computer mathematics Maple. Expressions for the forces in individual rods are found. The asymptotic approximation of solutions is obtained.

he filtration problem in a porous medium is an important part of underground hydromechanics. Filtration of suspensions and colloids determines the processes of strengthening the soil and creating waterproof walls in the ground while building the foundations of buildings and underground structures. It is assumed that the formation of a deposit is dominated by the size-exclusion mechanism of pore blocking: solid particles pass freely through large pores and get stuck at the inlet of pores smaller than the diameter of the particles. A one-dimensional mathematical model for the filtration of a monodisperse suspension includes the equation for the mass balance of suspended and retained particles and the kinetic equation for the growth of the deposit. For the blocking filtration coefficient with a double root, the exact solution is given implicitly. The asymptotics of the filtration problem is constructed for large time. The numerical calculation of the problem is carried out by the finite differences method. It is shown that asymptotic approximations rapidly converge to a solution with the increase of the expansion order.

Authors: Bhatti Tariq
Published: March 2018

The Takaful (Islamic Insurance) industry is still in infancy in the UAE. Almost eighty percent of the insurance industry is conventional, and the remaining is Takaful. A firm’s reputation is one of its most important intangibles resources, and it is a major source of competitive advantage and to improve financial performance. Many of the customers choosing their service provider consider reputation criteria among other factors. It is worth determining the antecedents and consequences of corporate reputation in the Takaful industry so that marketers can improve the reputation of their service providers and their industry by using various strategies to increase the loyalty and word of mouth among Takaful customers. The sample size is 325, and data was gathered from Takaful customers who have car Takaful policies. Scale and items for each construct were initially gathered from existing literature and then refined with the help of academic and industry experts. The measurement instrument used was analysed for reliability, convergent, and discriminant validity by means of confirmatory factor analysis. The research hypotheses were tested by using structural equation modelling. Corporate social responsibility (CSR), customer satisfaction, trust, and social media engagement proved to be most important antecedents of Takaful service providers. The findings suggest that Takaful marketers should consider in investing in effective reputation strategies to gain loyalty and perceived customer value. The study provides valuable insights into the antecedents and consequences of corporate reputation in the Takaful industry. Since this study focuses only on Takaful industry and was cross-sectional, further studies need to be done. This study found that corporate reputation is influenced by national culture, and it suggests effective strategies to improve the reputation of Takaful service providers compare to their counterparts in conventional insurance.
Development of Pure Sine Wave Inversion System with Inbuilt Charging and Display Mechanisms

Published: March 2018

In recent years, Nigeria’s power generation output from all the available energy sources such as coal, natural gas, and water, is far from the expected number required to meet the energy demand of her teeming populace. This culminates in long hours of power outages frequently experienced in many parts of the country. However, there appears to be no end in sight to the problem. Alternatively, few citizens who can afford generator have wittingly resulted to the use of this device to supply power. Generator set has unavoidable disadvantages of high maintenance or running cost, noise pollution, and release of dangerous gases that pose danger to human lives. Evidently, that solution is risky and inadequate. Power inverter is an alternative and better means of generating electricity with little or no maintenance cost, environment or eco- friendly and poses no risk to human health. It is in that connection that we develop in this work 2KVA sine wave inversion system which produces sinusoidal A.C. signal required in homes for lightning and powering electronic gadgets like television, radio, refrigerator, Air conditioner etc. It is an improvement over square wave and modified sine wave inversion systems that generate digital approximations of A.C. signal. An interesting but new addition is the use of LCD display, interfaced with PIC16F688 microcontroller for showing the design specifications of the inverter.
Electromagnetic Characteristics of Yagi-Uda Antenna at HF/VHF/UHF
Authors: Abimbola Raji A.
Published: March 2018

In this paper, the radiation characteristics of Yagi-Uda antenna operating at High Frequency (HF), Very High Frequency (VHF) and Ultra High Frequency (UHF) are examined. Upon employing method of moments, the current distribution on the antenna emerges from the solution of matrix equation. It is found that the angular distribution of electric field intensity generated in free space by the antenna, obtained by evaluating the integral of associated current distribution, is characterized by patterns with significant portion of radiation beam in the main lobe in the direction of Yagi axis. This is accompanied by relatively small undesirable radiation in the minor lobe, and which persist over those communication frequencies. It is observed also that the current distribution that generates the radiated electric field patterns is relatively consistent over the same range of frequency.

OBJECTIVE

Epidemiological studies suggest that smoking increases the risk of type 2 diabetes. We hypothesized that smoking-derived nicotine and ensuing activation of nicotinic cholinergic receptors in the gastrointestinal tract and the autonomic nervous system would have a detrimental effect on postprandial glucose metabolism and, thus, potentially constitute a link between smoking and the development of type 2 diabetes.

RESEARCH DESIGN AND METHODS

We subjected 11 male heavy smokers to two identical 4-h liquid mixed-meal tests: one with concomitant cigarette smoking (immediately before and after meal intake) and one without smoking. Twelve age-, sex-, and BMI-matched nonsmokers underwent an identical meal test without smoking.

RESULTS

The smokers were characterized by higher fasting plasma concentrations of glucagon compared with the nonsmokers. Among smokers, cigarette smoking before and after the meal significantly reduced postprandial plasma glucose excursions. There were no differences in gut or pancreatic hormone concentrations between the test days in the smoking group, and the responses were similar to those in the control group.

CONCLUSIONS

Our results suggest that smoking in association with meal intake decreases the postprandial plasma glucose concentrations, possibly through decreased gastric emptying, and that elevated fasting glucagon concentrations rather than smoking-induced alterations in postprandial glucose and hormone responses may be associated with the elevated risk of type 2 diabetes in chronic smokers.

Published: March 2018

The common goal of
the Water Framework Directive (WFD) published by The European Parliament and
European Council and the Regulation on the Management of Surface Water Quality
Directive (RMSWQ) published by the Republic of Turkey, Ministry of Forestry and
Water Affairs, is to provide all water bodies to achieve a fine ecological
status. These directives require the use of relevant biological quality
elements and diatoms constitute an important group within these elements. The
use of diatom based indices for assessing ecological conditions in inland water
systems is increasing day by day. The current study was performed with the aim
of determination of the ecological status of the Taşmanlı Pond based on
epilithic diatoms, physico-chemical parameters and to estimate pond water
quality using diatom indices. For this purpose, epilithic diatom and water
samples were collected from 3 stations in the pond in monthly intervals from
March 2008 to March 2009. The identifications of the sampled revealed presence
of a total of 46 taxa in the sampled stations. Achnanthidium minutissimum (Kützing) Czarnecki, Nitzschia acicularis (Kützing) W. Smith,
Navicula cincta (Ehrenberg) Ralfs in
Pritchard and Navicula cryptocephala
Kützing were the dominant taxa in all stations. According to Regulation on the
Management of Surface Water Quality directive, the pond water was classified as
III-IV quality class and trophic status changed from mesotrophic to eutrophic.
Significant correlation was determined between LTDI (Lake Trophic Diatom Index)
and EQR (Ecological Quality Ratio). The values of LTDI and EQR indicate that,
pond water has class III (poor, moderately polluted site) water quality.
