Published: May 2022

Evaluating the service quality of higher educational institutions in Bangladesh has become crucial to ensure continuous improvement and strategy development for tertiary education sector. The present study has aimed to investigate the influence of higher education service quality dimensions on student satisfaction and student loyalty. Moreover, the study also tests the mediating impact of university reputation and external prestige between university service quality and satisfaction and loyalty. The research work has shown the performance of selected public universities in higher education service quality dimensions. Data has been collected through a structured questionnaire from a sample of 390 graduate and undergraduate students of two public universities of Bangladesh. The study reflects that the performance on service quality dimensions of selected public universities is not satisfactory. The results of the study have shown that Teaching, Support services, Library and lab facilities and internationalization have significant influence on student satisfaction except Administrative service and Hostel facilities. Teaching, Administrative services, Library and lab facilities and Internationalization have significant influence on student Loyalty. The mediating analysis has shown that student satisfaction partially mediates between service quality and student loyalty. The results of the study have also indicated that university reputation and external prestige partially mediate between service quality and student satisfaction and loyalty. The previous studies which measure service quality of Bangladeshi higher educational institutions have applied SERVQUAL model which is not absolutely suitable for an educational institution. However, this study has applied higher education service quality model which has been uniquely developed to measure service quality of higher educational institutions.

Abstract
The Large Magellanic Cloud (LMC) is the nearest laboratory for detailed studies on the formation and survival of complex organic molecules (COMs), including biologically important ones, in low-metallicity environments—typical of earlier cosmological epochs. We report the results of 1.2 mm continuum and molecular line observations of three fields in the star-forming region N 105 with the Atacama Large Millimeter/submillimeter Array. N 105 lies at the western edge of the LMC bar with ongoing star formation traced by H2O, OH, and CH3OH masers, ultracompact H ii regions, and young stellar objects. Based on the spectral line modeling, we estimated rotational temperatures, column densities, and fractional molecular abundances for 12 1.2 mm continuum sources. We identified sources with a range of chemical makeups, including two bona fide hot cores and four hot core candidates. The CH3OH emission is widespread and associated with all the continuum sources. COMs CH3CN and CH3OCH3 are detected toward two hot cores in N 105 together with smaller molecules typically found in Galactic hot cores (e.g., SO2, SO, and HNCO) with the molecular abundances roughly scaling with metallicity. We report a tentative detection of the astrobiologically relevant formamide molecule (NH2CHO) toward one of the hot cores; if confirmed, this would be the first detection of NH2CHO in an extragalactic subsolar metallicity environment. We suggest that metallicity inhomogeneities resulting from the tidal interactions between the LMC and the Small Magellanic Cloud might have led to the observed large variations in COM abundances in LMC hot cores.

Abstract
We conduct intensity mapping to probe for extended diffuse Lyα emission around Lyα emitters (LAEs) at z ∼2−7, exploiting very deep (∼26 mag at 5σ) and large-area (∼4.5 deg2) Subaru/Hyper Suprime-Cam narrowband (NB) images and large LAE catalogs consisting of a total of 1540 LAEs at z = 2.2, 3.3, 5.7, and 6.6 obtained by the HSC-SSP and CHORUS projects. We calculate the spatial correlations of these LAEs with ∼1–2 billion pixel flux values of the NB images, deriving the average Lyα surface brightness (SBLyα
) radial profiles around the LAEs. By carefully estimating systematics such as fluctuations of sky background and point-spread functions, we detect Lyα emission at 100–1000 comoving kpc around z = 3.3 and 5.7 LAEs at the 3.2σ and 3.7σ levels, respectively, and tentatively (=2.0σ) at z = 6.6. The emission is as diffuse as ∼10−20–10−19 erg s−1 cm−2 arcsec−2 and extended beyond the virial radius of a dark matter halo with a mass of 1011
M
⊙. While the observed SBLyα
profiles have similar amplitudes at z = 2.2–6.6 within the uncertainties, the intrinsic SBLyα
profiles (corrected for the cosmological dimming effect) increase toward high redshifts. This trend may be explained by increasing hydrogen gas density due to the evolution of the cosmic volume. Comparisons with theoretical models suggest that extended Lyα emission around an LAE is powered by resonantly scattered Lyα photons in the CGM and IGM that originate from the inner part of the LAE and/or neighboring galaxies around the LAE.

Published: May 2022

Background:
Nausea and vomiting is a common complication after gynecological surgeries, especially laparoscopy, which can lead to discomfort and restlessness in the patients. The aim of the study was to compare the effect of ondansetron–dexamethasone and metoclopramide–dexamethasone on postoperative nausea and vomiting following gynecological laparoscopy.

Materials and Methods:
In this double-blind clinical trial, 68 females scheduled for gynecological laparoscopy and age range of 18–40 years were randomly divided into two groups. Group OD received ondansetron 4 mg plus dexamethasone 8 mg and group MD received metoclopramide 10 mg plus dexamethasone 8 mg, 15 min before the end of surgery. The incidence of nausea and vomiting and need for rescue medication was assessed during the recovery period, as well as at 2, 4, 6, 12, and 24 h after surgery. The data were analyzed using STATA software version 12 and a significance level of <0.05 was considered in this research.

Results:
The incidence of nausea in ondansetron and metoclopramide groups was 23.3% and 33.3%, respectively, and the frequency of vomiting was 10% and 16.6%, respectively, which showed no significant difference (P > 0.05). The highest incidence of nausea and vomiting in patients belonged to the metoclopramide group inside 4–6 h after surgery.

Conclusion:
Our study showed that no significant difference was observed in the incidence of nausea and vomiting between ondansetron–dexamethasone and metoclopramide–dexamethasone groups following laparoscopic gynecological surgery; however, the number of patients with nausea and vomiting was lower in the ondansetron–dexamethasone group.

Published: May 2022

Background:
Clinical, pathologic, and genetic heterogeneity is a challenge in identifying and classifying congenital dyserythropoietic anemia (CDA). CDA type IV, the rarest CDA with only 11 reported cases, results from KLF1 gene mutation.

Clinical Description:
A male preterm neonate presented with jaundice, anemia, pulmonary hypertension and hepatosplenomegaly in the immediate postnatal period, requiring multiple red blood cell transfusions.

Management and Outcome:
The workup for non-immune haemolytic anemia including red blood cell structural and enzymatic studies and were normal, with peripheral blood smear showing multiple polychromatic cells and numerous nucleated red blood cells including binucleate ones and fetal haemoglobin of 91.2%. Genetic testing revealed KLF1 E325K mutation suggestive of CDA type IV, though parental testing was normal, suggesting de novo mutation. The infant has been receiving packed RBC transfusion every three to four weeks initially and then every two months. The baby is now of twelve months of age, and receives oral vitamin B12 and folic acid supplementation for ineffective erythropoiesis. Though his weight is in the 3rd centile for age and height, he has been developmentally normal.

Conclusions:
Our report, the first description of a CDA type IV diagnosis in the neonatal period, adds to the limited knowledge of this disorder, which we also comprehensively review. The report highlights the phenotype of the disorder and the importance of neonatal genetic testing in a case of transfusion dependent anemia, having ruled out other causes.

Utilization of solar power can use a thermoelectric generator. Thermoelectric Generators work by taking advantage of temperature differences and the application of the Seebeck effect. This experimental study uses two prototypes of a perfect house with a roof made of zinc plate. One of the roofs of the house is covered with glass. Thermoelectrics are installed at the bottom of the roof of each house as many as 12 pieces and arranged in a series circuit. Data collection was carried out one day from 08.00 -15.59. The largest electrical voltage obtained occurred at 11.00 – 13.59 reaching 0.215 – 0.183 Volts in houses with glass-covered roofs and 0.654 – 0.527 Volts. The use of a layer of glass makes the roof temperature stable because the heat absorbed can be retained by the glass. As a result, the voltage generated in a house with a glazed roof is more stable than a house with a non-glazed roof. This research also proves that the difference in temperature affects the voltage generated by the thermoelectric.

Population growth is caused by three components, namely birth (fertility), death (mortality), and migration. These three components greatly affect the process of population growth that occurs. The development of population growth in one sub-district is very important to be detailed so that the development of the subdistrict can be improved. Forecasting is an important tool in effective and efficient planning. An important step after forecasting is done is verification of forecasting in such a way that it reflects past data and the underlying causal systems of such growth. As long as the forecasting representation is reliable, forecasting results can continue to be used. The purpose of this study is to apply the Trend Moment method to predict the population growth in Joman Water District in the next few years based on three components, namely birth (fertility), death (mortality), and migration. The results of this study can predict the number of population growth using the Trend Moment Method in 2022 with birth rates of 1573, 641 arrivals, 601 arrivals, and 235 displacements with errors below 10%

INCREASED EFFICIENCY OF LEACHING OF RADIONUCLIDES, HEAVY AND RARE METALS FROM SOILS AND WASTES OF MOUNTAIN AND TECHNOLOGICAL MANUFACTURES
Authors: Brovka G. P. , Dorozhok I. N. 
Published: May 2022

The article considers the methods of multiple and multi-stage leaching, as well as leaching in countercurrents with solutions that allow to transfer to a water-soluble state of the required amount of highly sorbable compounds, such as radionuclides, heavy and rare metals from soils, rocks and wastes of mining industries. The developed methods of calculation are presented, allowing due the choosing of optimal methods and parameters to reduce the consumption of solutions and increase the concentration of extracted elements in them. It has been established that the most promising methods of extraction are multistage leaching and exchange in countercurrents of the leaching solution and the material to be processed.
The removal of radionuclides from soils and the extraction of rare metals from mining waste can be carried out by leaching, which requires a large consumption of chemical reagents. Therefore, it becomes necessary to identify the optimal leaching parameters by mathematical modeling. With this aim, the article proposed methods to reduce the consumption of leaching solutions, and determined the optimal parameters of leaching under specified conditions. For all the methods considered, analytical solutions are given that allow calculating the degree of purification from the extracted compounds, the consumption of the leaching solution and its concentration. А system of equations for multi-stage leaching has been solved. It was found that with a distribution coefficient of 5, in order to achieve a purification degree of 10 %, 3 times less solution will be consumed with four-fold leaching than with one-time leaching, and with multistage
leaching, 9 times less.
