Micronutrient malnutrition and wasting in adults with pulmonary tuberculosis with and without HIV co-infection in Malawi.
Get PDFBACKGROUND: Wasting and micronutrient malnutrition have not been well characterized in adults with pulmonary tuberculosis. We hypothesized that micronutrient malnutrition is associated with wasting and higher plasma human immunodeficiency virus (HIV) load in adults with pulmonary tuberculosis. METHODS: In a cross-sectional study involving 579 HIV-positive and 222 HIV-negative adults with pulmonary tuberculosis in Zomba, Malawi, anthropometry, plasma HIV load and plasma micronutrient concentrations (retinol, alpha-tocopherol, carotenoids, zinc, and selenium) were measured. The risk of micronutrient deficiencies was examined at different severity levels of wasting. RESULTS: Body mass index (BMI), plasma retinol, carotenoid and selenium concentrations significantly decreased by increasing tertile of plasma HIV load. There were no significant differences in plasma micronutrient concentrations between HIV-negative individuals and HIV-positive individuals who were in the lowest tertile of plasma HIV load. Plasma vitamin A concentrations <0.70 micromol/L occurred in 61%, and zinc and selenium deficiency occurred in 85% and 87% respectively. Wasting, defined as BMI<18.5 was present in 59% of study participants and was independently associated with a higher risk of low carotenoids, and vitamin A and selenium deficiency. Severe wasting, defined as BMI<16.0 showed the strongest associations with deficiencies in vitamin A, selenium and plasma carotenoids. CONCLUSIONS: These data demonstrate that wasting and higher HIV load in pulmonary tuberculosis are associated with micronutrient malnutrition
Аналітична оцінка струму рекомбінації різкого асиметричного p-n переходу
No full textПри моделюванні асиметричного p-n переходу високолегована область в наближенні малих струмів не впливає на розподіл носіїв в низьколегованої області, в якій зосереджений весь об'ємний заряд. У даній роботі проведена аналітична оцінка струму рекомбінації через пастки в області просторового заряду і в квазинейтральной області. Для отримання аналітичного уявлення застосовується наближення лінійності розподілу потенціалу в околиці перетину максимальної рекомбінації. Запропоновано методику аналітичної оцінки інтеграла питомої об'ємної швидкості рекомбінації по області просторового заряду, що не береться через елементарні функції. Підтверджено можливість підвищення точності аналітичної оцінки рекомбінаційного струму через пастки в області просторового заряду. Визначено диференційний коефіцієнт ідеальності і проаналізована його динаміка в залежності від напруги на переході. Виконано порівняльний аналіз наступних оцінок струму рекомбінації: струм рекомбінації в області просторового заряду за елементарної оцінки, дифузний струм з низьколегованої квазинейтральной області, струм рекомбінації через пастки в квазинейтральной області, струм у разі лінійної апроксимації потенціалу в області максимальної рекомбінації через аналітичний інтеграл, реальний струм рекомбінації. Наведено аналіз похибки розрахунку струму рекомбінації від рівня легування слаболегірованних області і прикладеної напруги. З наведених даних видно, що оцінка похибки розрахунку струму через аналітичний інтеграл не перевищує 10 % що цілком достатньо для її застосування при моделюванні струму рекомбінації більшості силових напівпровідникових приладів.When simulating an asymmetric p-n junction, the high-alloyed region in the approximation of small currents does not affect the distribution of carriers in the low-alloyed region, in which the entire volume charge is concentrated. In this paper, an analytical estimate of the recombination current through traps in the space charge region and in the quasi-neutral region was made. To obtain an analytical representation, an approximation of the linearity of the potential distribution in the vicinity of the maximum recombination
cross section is used. A method is proposed to analytically estimate the integral of the specific volume recombination rate over a region of the space charge that cannot be taken through elementary functions. The
possibility of increasing the accuracy of the analytical estimate of the recombination current through traps
in the space charge region was confirmed. The differential ideality coefficient is determined and its dynamics is analyzed depending on the voltage at the junction. Comparative analysis of the following recombination current estimates was made: the recombination current in the space charge region by elementary estimate, the diffusion current from the low-alloyed quasi-neutral region, the recombination current through traps in the quasi-neutral region, the current in the case of a linear approximation of the potential in the region of maximum recombination through the analytical integral, the real recombination current. An analysis of the error in the calculation of the recombination current from the doping level of the low-doped region and the applied voltage is presented. From the above data it can be seen that the error estimate for calculating the current through the analytical integral does not exceed 10 %, which is quite enough for its use in simulating the recombination current of most power semiconductor devices
Business consulting in Russia : business development plan for company X
Get PDFIn 2014, the first sanctions against Russia were imposed because of the conflict between Russia and Western countries during the Ukraine crisis. These sanctions initiated an economic crisis in Russia, led to countersanctions from Russia against Western countries and the USA and caused changes in the import and export policies between Russia and Western countries. As a result, the Russian market became less attractive to foreign investors what has influenced the business performance of Company X.

Analysis of methods for accounting cargo vehicles in traffic flow of a regulated crossroad
Get PDFIntroduction. The formation of a ‘cargo frame’ around large cities leads to a change in the composition of the traffic flow on bypass roads, and an increase in the total traffic flow of trucks of various categories. In addition, the active development of suburban areas with residential complexes contributes to an increase in traffic. The totality of the reflected phenomena leads to the emergence of a certain kind of transport problems, primarily associated with a decrease in throughput. Quite often, such problems are observed at regulated intersections, which requires a prompt change in the control mode; for this, the necessary measure is the mandatory consideration of the technical and dynamic parameters of trucks, which are not fully taken into account in the existing reduction factors. In order to establish the degree of influence of these parameters on the change in the main characteristics of the traffic flow, such as the average travel time and average speed, this study was carried out.Methods and materials. When performing the study, the methods of natural observation, statistical analysis and modelling were applied. The necessary materials for the study were devices for automatic collection of traffic flow characteristics, such as video cameras and traffic detectors, Any Logic version 8.0 for modelling, and a package of descriptive statistics in MS Excel.Results. In the course of the study and the experiment, a difference in the main characteristics of the traffic flow when using standard reduction factors and without using them, taking into account the dynamic and technical parameters of trucks was established. At the object of the study, the difference in the value of the average travel time () for various methods of accounting for trucks, observed in the range [-51.5%; 16.8%] and average speed () in the range [20%; 34%] was determined. As a result of mathematical research, functional relationships between the average speed and traffic intensity are determined, taking into account the presence of trucks of various categories, their technical and dynamic parameters. The ways of further research are determined
Estimation of truck reduction factors applicable to calculation of parameters of a regulated intersection
Get PDFIntroduction. The rapid growth of the country’s car park and the increasing rate of traffic volume lead to various types of transport problems. This is especially acute in regulated areas located near logistics parks, as well as in industrial zones of cities. Here, in the general traffic flow, trucks prevail, which differ from passenger cars primarily in their overall dimensions and dynamic characteristics. For the uniformity of the traffic flow, a certain difference is compensated by specialized coefficients of converting to a conventional passenger car. The performed research is aimed at establishing the main methods used in bringing freight vehicles to a conventional passenger car and assessing the current coefficients of converting freight vehicles to a conventional passenger car by determining the value of the reduced traffic intensity.Methods and materials. Within the framework of the study performed, natural methods of data collection were used for the subsequent calculation. When analyzing certain parameters, mathematical models have been established that underlie certain values of the coefficients of converting trucks to a conventional passenger car.Results. In the course of the study, the authors classified the methods for determining the coefficients of bringing a truck to a conventional passenger car. The values of the reduction factors for some of them have been established, which can be used when calculating the parameters of the regulated section. The present value of road traffic on the set object of the study - the regulated intersection - has been calculated using different actuation coefficients established earlier. The results obtained are assessed.Conclusion. The analysis of the values obtained as a result of calculations showed their significant difference from each other with a difference of 12%, 53% and 300% of the value of the total (not reduced) intensity. Based on the results obtained, the main tasks of further research are determined

Valeriy O. Zhamardiy, Olena M. Shkola, Oleg Yu. Zakharov, Volodymyr G. Saienko , Hanna V. Tolchieva // Journal of the polish balneology and physical medicine association, 2021. – № 3 (164). – Р. 160–164Aim: The article experimentally examines the effect of rehabilitation measures on increasing the volume of movements of the cervical spine, taking into account the severity of muscle pain in children with cerebral palsy.
Materials and Methods: The study involved 168 children with spastic forms of cerebral palsy, they were divided into two observation groups: the main group, which conducted the proposed rehabilitation course (n = 98) and control, who underwent a course of conventional rehabilitation content (n = 70).
Results: During application of the proposed method, the therapeutic effect on pathologically significant areas of bilateral muscle kinematic chains was carried out taking into account their mutual antagonism, bilateral symmetry, taking into account the course of homolateral and heterolateral muscle spirals. Positive dynamics in the clinical status in the vast majority of patients during re-observation was achieved, but the effectiveness of rehabilitation and the stability of the achieved therapeutic effect in the study groups were different. Thus, in patients of the main and control groups, changes in the mobility of the cervical spine were detected, which were recorded using the proposed integrated assessment. Namely, in patients who were engaged in the proposed method, the amount of movement in the cervical spine (passive lateral tilt with an element of rotation) probably increased when compared with the indicators before rehabilitation. Also noteworthy is statistically significant reduction in pain intensity, which allows for more manipulative rehabilitation.
Conclusions: The proposed method of rehabilitation of children with spastic forms of cerebral palsy has a pronounced sanogenetic effect, meaning it stimulates their own health reserves and triggers a cascade of reactions of the body aimed at forming a healthy motor stereotype.
It involves influence on organism of the patient by rehabilitation procedures with inclusion in work of all biokinematic muscular chain at the same time, taking into account spiral construction of muscles of a body, which allows to achieve a more pronounced therapeutic effect
