Association Between Neonatal Hyperbilirubinemia and Serum Zinc Levels in Dhaka City of Bangladesh

Neonatal hyperbilirubinemia is a common clinical condition in the first week of neonatal life. The common causes are haemolytic disease of the newborn (rhesus), ABO incompatibility, glucose-6-phosphate dehydrogenase deficiency, spherocytosis and infection. Any study was not conducted in Bangladesh to find out the correlation between neonatal hyperbilirubinemia and zinc level. So, the objective of this was to evaluate the correlation between the level of serum zinc and neonatal hyperbilirubinemia in Dhaka city of Bangladesh. This cross sectional study was done at Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, Bangladesh. Total 594 numbers of sample were collected from neonatology department of BSMMU from January 2016 to April 2019 and samples were divided in two groups. Case group and control group consists 319 and 275 numbers of sample respectively. All the laboratory parameters were done at clinical pathology department of BSMMU by automated analyzer machine and strictly followed quality control. Data obtained were analyzed using the Statistical Package for the Social Science (SPSS) version 20. Results were considered statistically significant if p<0.05. The result showed that the level of serum bilirubin was 171.14 mg/L and 35.42 mg/L and the level of serum zinc was (0.50 mg/L) and (0.68mg/L) in case and control group respectively. The bilirubin level was significantly (p<0.001) high in case group and zinc level was significantly (p<0.001) decreased in case group when compared with control group. Is also showed there was a significant (p value<0.001) correlation between hyperbilirubinemia and serum zinc level in this study. Therefore, it can be concluded, the deficiency of zinc may have a relationship followed by in neonatal hyperbilirubinemia.
Trust in open data applications through transparency

Open data provide great potential for society, for example, in the field of smart cities, from which all citizens might profit. The trust of these citizens is important for the integration of various data, like sensitive user data, into an open data ecosystem. In the following study, we analyzed whether transparency about the application of open data promotes trust. Furthermore, we formulated guidelines on how to create transparency regarding open data in an ethical way. Using an open-data-based fictitious smart city app, we conducted an experiment analyzing to what extent communication of the technical open data application process and the ethical self-commitment for the transparent communication of data application affect trust in the app’s provider. The results indicate that the more information users obtain regarding the use of open data, the more trustworthy they perceive the app provider to be, and the more likely they are to use the app.
Size effects and lattice disorder in GeS2/CdSe nanostructures

This article summarizes results on GeS 2 /CdSe superlattices (SLs) and composite films (CFs) which are prepared by consecutive thermal evaporation of CdSe and GeS 2 in vacuum. An overall blue shift of the absorption spectra of SLs is observed with decreasing CdSe layer thickness related to a size-induced increase of the optical band gap of CdSe due to one-dimensional carrier confinement in the continuous nanocrystalline CdSe layers. This assumption is proven by the results of photoreflectance measurements. A number of features are observed in the absorption spectra of CFs. They are discussed in terms of three-dimensional carrier confinement and considered as a manifestation of excited electron states in CdSe nanocrystals. Resonant Raman effects are observed in the CFs and related to resonant absorption in the excited electron states. Electronic defects in CdSe nanocrystals of SLs and CFs are investigated by transient and spectral photocurrent investigations. Two wide bands of localized states centred at 0.55 eV and 0.50 eV below the conduction band edge are seen and identified with defects in the nanocrystal bulk and defects at the GeS 2 /CdSe interface, respectively. The effect of CdSe nanocrystal incorporation on the level of disorder in the GeS 2 matrix of CFs is also investigated. It is observed that the presence of CdSe nanocrystals with average diameter >2.5 nm in the GeS 2 matrix impedes the photoinduced structural changes in GeS 2 .

The relationship between physical education and sport values with self-reported personal and social responsibility behaviours

The aim of this research was to determine the level of values related to the subject of physical education and sport with self-reported personal and social responsibility behaviours in students studying in secondary school and to examine the relationship between them. For this purpose, this study, which was carried out with the participation of 1138 secondary school students from 13 different secondary schools in Balıkesir/Turkey, was conducted with a multi-factor predictive correlational design. “Physical Education and Sports Lesson Value Scale” and “Personal and Social Responsibility Behaviours Scale” were used in collecting the data. Pearson correlation analysis and multiple linear regression analysis were used in the analysis of the data. It was determined that students’ values related to the subject of physical education and sport with their self-reported personal and social responsibility behaviours were at a high level. When the mean scores in the sub-dimensions of the scale of values related to the subject of physical education and sport are examined, it is seen that the most important values were considered to be awareness and respect, in that order, and that the values with the lowest mean scores were sports culture and national culture and unity. According to the results of multiple linear regression analysis, the values of respect, awareness, healthy life and nutrition, national culture and unity, solidarity, and sports culture explained 42 and 47% of the variance personal and social responsibility, respectively. As a result, it can be said that physical education and sport values are important variables in predicting the self-reported personal and social responsibility behaviours of secondary school students.
Physical Guidance of Cultured Retinal Neurons Using Zig-zag Surface Patterns

The use of physical cues to control and guide various types of cells in vitro, especially neurons and their processes, has been the focus of a large amount of research. The response of neuronal processes to artificial surfaces depends on a number of factors including the cell type, the surface chemistry of the material, and the surface’s topological features [1,2]. In this Opinion piece, we investigate the extent to which retinal neuronal processes can be made to follow straight lines patterned into a surface. We show they can follow lines with relatively shallow heights of 2 μm and be made to undergo directional changes as great as 50°. However, some processes leave the lines and assume a weaving trajectory as they grow into the surface’s unpatterned regions. Based on these findings, we propose that neuronal processes will follow lines more closely if their shapes mimic the fractal weave patterns of unrestricted neurons. In addition to exploring the fundamental behavior of neurons interacting with artificial surfaces, the results inform the design of bio-inspired electrodes for human implants. Materials and Methods
Electron transport in molecular junctions

This thesis addresses the electron transport in molecular junctions, focusing on the energy level alignment and correlation effects. Various levels of theory have been applied to study the structural and electronic effects in different molecular junctions, starting from the single particle density functional theory (DFT) description over the semi-empirical DFT+Σ, to the sophisticated fully self-consistent GW approach. We find that in order to obtain a quantitative description of the conductance and the thermopower, it is necessary to go beyond the single particle description. The effect of side groups on the benzene-diamine (BDA) molecule has furthermore been studied and it is found that the correct energy level alignment for the BDA molecule in Au contacts is only captured by the GW approach. Consequently, the GW approach provides an accurate description for the conductance change resulting from the side groups. The failure of the DFT based description is due to the strong energy level pinning when the BDA molecule is in contact with Au contacts. The effect of contact geometries on the conductance and the thermopower has also been addressed. It is found that both GW and the DFT+Σ with a certain image charge position are in quantitative agreement with the experiments, while pure DFT is not. This is the consequence of the accurate energy level alignment, where the DFT+Σ method corrects the self-interaction error in the standard DFT functional and uses a static image charge model to include the image charge effect on the energy level renormalization. Additionally, the gating of the 4,4’-bipyridine (44BP) molecule contacted to either Ni or Au electrodes has been investigated. Here it is found that the
Dualism or solidarity? Conditions for union success in regulating precarious work

This article summarizes and reviews research on union responses to precarious work in Europe, based on a systematic coding of 56 case study-based articles published between 2008 and 2019. Analyses of these cases suggest two paths to labour market dualism, with the first involving institutional fragmentation and union division, and the second a combination of weak structural power and partnership-oriented union identities. The authors also identify two paths to solidarity, with the result of reduced precarity for peripheral workers: a conflict-based path and a social partnership-based path. Campaigns to organize migrant workers present distinctive institutional and structural challenges to unions, with studies involving migrants most often finding ‘failed solidarity’, in which inclusive organizing fails to reduce precarity. The article integrates these findings with past frameworks on union responses to precarious work and concludes with recommendations for future research.
Monitoreo de residuos de plaguicidas en ajíes dulces en mercados selectos de San José de Ocoa y Santo Domingo, República Dominicana

Dominican agricultural products for export purposes are constantly tested for pesticide residues. These agro-foods present high concentrations of pesticides that exceed the established maximum residue levels (MRLs), becoming a food safety concern. The objective of this study was to identify the presence, types and concentrations of 70 pesticide residues commonly used in the horticultural sector in two cultivars of peppers using the gas chromatography technique coupled to mass spectrometry (GC-MS), in selected food markets from the San Jose de Ocoa province and Gran Santo Domingo. Between January 2018 and June 2019, 117 sweet pepper samples were collected and were analyzed using the QuEChERS multiple residue extraction, followed by GC-MS. It was found that only 62% complied with the MRLs, with chlorphenapir and cyhalothrin being the most frequently detected (27 and 19 samples, respectively). Also, the presence of 19 varieties of pesticides were identified, including two illegal organochlorines: dicofol and dichlorodiphenyltrichloroethane (DDT). The high levels and wide variety of pesticide residues detected in this project suggest the need to enact regulations on the proper use of pesticides.

Zero‐inflated modeling part II: Zero‐inflated models for complex data structures

The prequel to this review provided an extensive treatment of classic zero‐inflated count regression models where a univariate discrete distribution is used for the count regression component of the model. The treatment of zero inflation beyond the classic univariate count regression setting has seen a substantial increase in recent years. This second review paper surveys some of this recent literature and focuses on important developments in handling zero inflation for correlated count settings, discrete time series models, spatial models, and multivariate models. We discuss some of the available computational tools for performing estimation in these settings, while again highlighting the diverse data problems that have been addressed using these methods.
Real-Time Monitoring of the Thermal Effect for the Redox Flow Battery by an Infrared Thermal Imaging Technology

In this study, a new monitoring method was developed, titled infrared thermal imaging technology, which can effectively evaluate the thermal effect of the charge-discharge test in the vanadium/iodine redox flow battery (V/I RFB). The results show that the all-vanadium redox flow battery (all-V RFB) has a greater molar reaction Gibbs free energy change than that of the V/I RFB, representing a large thermal effect of the all-V RFB than the V/I RFB. The charge-discharge parameters, flow rate and current density, are important factors for inducing the thermal effect, because of the concentration polarization and the ohmic resistor. The new membrane (HS-SO3H) shows a high ion exchange capacity and a good ions crossover inhibitory for the V/I RFB system, and has a high coulomb efficiency that reaches 96%. The voltage efficiency was enhanced from 61% to 86% using the C-TiO2-Pd composite electrode as a cathode with the serpentine-type flow field for the V/I RFB. By adopting the high-resolution images of an infrared thermal imaging technology with the function of the temperature profile data, it is useful to evaluate the key components’ performance of the V/I RFB, and is a favorable candidate in the developing of the redox flow battery system.
Selection of location of radiators in a non-equivident antenna array

Antennas are one of the main elements of radio engineering systems. Phased antenna arrays (PAR), which make it possible to regulate the direction of radiation due to the ability to control the phases or phase differences of the emitted signal, are the most effective types of antennas. The size, design and shape of the PAR depend on the tasks to be solved, the type of emitters and the nature of their location. The article discusses the transformation of an equidistant PAR into a non-equidistant antenna array in order to reduce the level of side lobes and suppress diffraction maxima with a given minimum distance between the emitters. A model of a non-equidistant antenna array and calculation formulas for its analysis are presented. The method presented in the work based on iterative calculation methods makes it possible to select the main parameters of a non-equidistant PAR taking into account the bonds formed between neighboring radiating elements. The coordinates of the emitter elements of the non-equidistant PAR were calculated in a program using the MATLAB language. At the same time, a method was implemented to search for the optimal arrangement of emitters relative to each other, in which the directional pattern of the antenna array will have a minimum level of diffraction maxima and the required level of side lobe. According to the results of the program execution, the coordinates of the new non-equidistant PAR were obtained. The non-equidistant phased array antenna simulated according to the calculation results showed a complete absence of diffraction maxima, in contrast to the equidistant array, but it was not possible to sufficiently obtain the required level of side lobes. The calculated antenna radiation patterns presented for comparison showed the advantages of a non-equidistant antenn array.
MILK AND DAIRY PRODUCTS MARKET IN AKMOLA REGION OF KAZAKHSTAN

Recommendations for solving the problems of sustainable development of milk and dairy products market in the region are based on the study of its current state and promising directions. The dynamics of production of milk and its processing products, export and import, livestock and productivity of cows is analyzed. The contribution of various categories of farms to the receipt of raw milk has been studied, while the lag in milk yield in farms and households from agricultural enterprises has been revealed. The analysis of expenses in agricultural enterprises is presented, as well as the structure of material costs. The main problems of effective development of the industry of dairy cattle breeding include tendency to reduce the area under fodder crops; a weak feed base and increase in feed prices, which leads to the increase in the cost of milk; reduction in the number of dairy cows; small commodity farms, that is, the concentration of main volumes of milk production in households where the introduction of intensive innovative technologies is difficult; seasonality of the process; non-observance of veterinary and sanitary standards. The regional features of location of dairy processing enterprises have been investigated, confirming the close relationship between the development of the dairy industry and the raw material base. Those of them have been identified, which account for the largest share in production of the range of dairy products. The organizational structure of the milk processing enterprise "Gormolzavod" LLP was studied, the calculation of butter was made using its own raw materials. The competitive advantages of the processing enterprises of the region are revealed.
Reduction effect of electromagnetic radiation emitted from mobile phones on human head using electromagnetic shielding materials

Since the development of wireless technology we have been benefitted in many ways while becoming more susceptible to the electromagnetic radiations as electromagnetic radiations are the basic means of transmission in this technology. There has been many advancements in the technology which leads to the increased possibilities of exposure to the radiations . The constant exposure to the radiations is found be hazardous to the health of the person. There has been many efforts made by the scientist and research community so as to mitigate the bad effects of radiations by using the shielding materials which absorb the radiations. In this paper we have tried reducing the effect of electromagnetic radiations coming from mobile phones on human head. We used 6 materials as shielding materials. They are germanium, silver, nickel, ferrite, polyurethane and ABS. We conducted thermal analysis in ANSYS workbench. The results are showing that the heat flux developed and the temperature rise is minimum in case of polyurethane while it is maximum with silver.
Exploring Generalization Capacity of Artificial Neural Network for Myelin Water Imaging

Purpose: To understand the effects of datasets with various parameters on pre-trained network performance, the generalization capacity of the artificial neural network for myelin water imaging (ANN-MWI) is explored by testing datasets with various scan protocols (i.e., resolution and refocusing RF pulse shape) and types of disorders (i.e., neuromyelitis optica and edema). Materials and Methods: ANN-MWI was trained to generate a T 2 distribution, from which the myelin water fraction value was measured. The training and test datasets were acquired from healthy controls and multiple sclerosis patients using a multiecho gradient and spin-echo sequence with the same scan protocols. To test the generalization capacity of ANN-MWI, datasets with different settings were utilized. The datasets were acquired or generated with different resolutions, refocusing pulse shape, and types of disorders. For all datasets, the evaluation was performed in a white matter mask by calculating the normalized root-mean-squared error (NRMSE) between the results from the conventional method and ANN-MWI. Additionally, for the patient datasets, the NRMSE was calculated in each lesion mask. Results: The results of ANN-MWI showed high reliability in generating myelin water fraction maps from the datasets with different resolutions. However, the increased errors were reported for the datasets with different refocusing pulse shapes and disorder types. Specifically, the region of lesions in edema patients reported high NRMSEs. These increased errors indicate the dependency of ANN-MWI on refocusing pulse flip angles and T 2 characteristics. Conclusion: This study proposes information about the generalization accuracy of a trained network when applying deep learning to processing myelin water imaging.
Laboratory sources of gravitational waves

We consider the possibility of generating and subsequently detecting artificial gravitational waves in a laboratory based on different approaches. As one of the methods for creating gravitational waves, we investigate oscillations of the ions of the crystal lattice of a dielectric under the influence of high-power laser radiation. The characteristics of gravitational waves obtained by this method are compared with the results of using the other approaches as well.
