Published: October 2021

Background and purpose: There is concern that students may have an unhealthy lifestyle as a result of changes that occurred during corona conditions, so this study aimed to determine the status of the lifestyle and its relationship with the demographic characteristics of postgraduate students during the corona span.
Material and Methods: This cross-sectional study was conducted at Tehran University of Medical Sciences in 2020. The link to the online Health-Promoting Lifestyle Questionnaire Profile2 was sent to conduct the research. To examine the relationships between the mean scores of health-promoting lifestyle and different variables, an independent samples t-test was applied in the case of dichotomous demographic variables (gender, education level, and income-generating activity), while one-way analysis of variance test was used to evaluate the multilevel demographic variables (marital status, place of residence, and faculty). The Pearson correlation coefficient was also used for testing age.
Results: The sample 240, (75.4%) were female and 145 of them, (60.4%) were single. The mean age of them was 32.21±7.45.45 years old. The lifestyle total score was 138.28± 21.18 at the average level. The highest score was related to spiritual growth (26.93±5.01), whereas the lowest score was reported on physical activity (16.92±5.17). The difference between the mean of health-promoting lifestyle was not significant in terms of demographic variables.According to the results, a statistically significant difference was observed between male and female students in the field of nutrition. Also, students were significantly different in the nutrition domain regarding students’ residence (p-value <0.05). Spiritual growth was significantly different among students in terms of marital status (p-value <0.05).
Conclusion: Although the mean score of health-promoting lifestyle was not different from other studies, further studies are proposed to plan health interventions in accordance with epidemic conditions for students.

This paper reports the evaluation of digestibility, immunological parameters, and resistance to thermal shock at low temperature in Litopenaeus vannamei fed diets with diferent Aurantiochytrium sp. meal additions (0; 0.5; 1 and 2%). First, the apparent digestibility coefficient of the ingredient was determined. The digestibility of the microalgae meal was high for protein (74.90%); around 60% for lipids, and for docosahexaenoic fatty acid (DHA) it was 55.61%. After, shrimp rearing with the feed additive was carried out in a clear water system, containing 25 shrimp (initial weight: 4.89 Â± 0.27 g) per 400 L tank. Feeding occurred four times a day. After a three-week period, immunological parameters were evaluated and thermal shock was performed. Animals fed 0.5% and 2% of the microalgae Aurantiochytrium sp. showed higher survival to thermal shock. In immunological analyses, the serum agglutiniting titer was higher (p <0.05) in the 0.5 and 2% additions of the microalgae meal, and the phenoloxidase activity (PO) was higher in the 1% addition (p <0.05). It is concluded that there is good utilization of the nutrients of Aurantiochytrium sp. meal by L. vannamei and its addition to the diet (0.5 and 1%) increased shrimp resistance to thermal shock.

Published: October 2021

The present study evaluated the use of the indigenous probiotic Lactobacillus plantarum and commercial probiotic containing Bacillus spp. in the culture of L. vannamei in a biofloc system. Shrimp were fed with four diets: L. plantarum, Bacillus spp., L. plantarum + Bacillus spp. and feed with no additives. Growth performance, water quality variables and microbiological counting of water and digestive tract of shrimp were determined. The control group and L. plantarum treatment showed better growth performance. The highest feed conversion ratio (FCR) and the lowest survival were obtained in the L. plantarum + Bacillus spp. treatment, which had significantly higher nitrite values. Vibrio spp. counts in the water were lower in the L. plantarum and L. plantarum + Bacillus spp. treatments and were lower in the intestinal tract in the L. plantarum treatment. Lactic acid bacteria (LAB) was higher in the L. plantarum treatment in the water and digestive tract. The count of total heterotrophic bacteria (THB) deferred only among Bacillus spp. and L. plantarum + Bacillus spp. treatment, being higher in the latter group. In Bacillus spp. treatment, no presence of LAB was detected in the water or intestinal tract. We conclude that the use of L. plantarum combined with Bacillus spp. negatively affected survival, FCR and water quality, but that the use of L. plantarum alone reduced the presence of Vibrio spp., even though it did not change the growth performance of L. vannamei.

AbstractTight sandstone reservoirs are widely distributed worldwide. The Upper Triassic Chang 6 member of the Yanchang Formation is characterized by low permeability and porosity. The facies model offers a unique approach for understanding the characteristics of various environments also heterogeneity, scale, and control of physical processes. The role of subsurface facies features and petrophysical properties was unclear. Notable insufficient research has been conducted based on facies and petrophysical modeling and that demands to refine the role of reservoir properties. To tackle this problem, a reservoir model is to be estimated using various combinations of property modeling algorithms for discrete (facies) and continuous (petrophysical) properties. Chang 6 member consists of three main facies, i.e., channel, lobe main body, and lobe margin facies. The current research is aimed at comparing the applicability and competitiveness of various facies and petrophysical modeling methods. Further, well-log data was utilized to interpret unique facies and petrophysical models to better understand the reservoir architecture. Methods for facies modeling include indicator kriging, multiple-point geostatistics, surface-based method, and sequential indicator simulation. Overall, the indicator kriging method preserved the local variability and accuracy, but some facies are smoothed out. The surface-based method showed far better results by showing the ability to reproduce the geometry, extent, connectivity, and facies association. The multiple-point geostatistics (MPG) model accurately presented the facies profiles, contacts, geometry, and geomorphological features. Sequential indicator simulation (SIS) honored the facies spatial distribution and input statistical parameters. The porosity model built using sequential Gaussian simulation (SGS) showed low porosity (74% values &lt;2%). Gaussian random function simulation (GRFS) models showed very low average porosity (8%-10%) and low permeability (less than 0.1 mD). These methods indicate that Chang 6 member is a typical unconventional tight sandstone reservoir with ultralow values of petrophysical properties.

Abstract
In October 2019, electrical submersible pump (ESP) XY-107 experienced an overload shutdown. Troubleshooting actions have been conducted such as reverse rotation, used rocking method, voltage boost, inject gas through the annulus, and even fluid circulation, yet still failed to reactivate the well. Pump stuck condition was suspected and urgently need a solution.
A study was performed to determine the cause of pump stuck. XY-107 is produced from limestone formation, therefore suggesting possibility of scale deposit formation in this well. Upon physical inspection inside the well's flowline, lump of deposit was recovered and suspect similar material could have occurred inside the pump. Rig intervention is a common solution for the ESP pump stuck condition. However, it required high cost (around 80,000 USD) and a longer well service job period up to 5 days. With scale deposit as the suspect, an unconventional solution was proposed to soak the well with acid to dissolve stuck-material by rigless operation. It was much cheaper than rig intervention (only about 4,000 USD) and with a shorter time of 1 day. Yet, acid selection is critical to avoid material damage during operation. Since conventional acid system is known to be corrosive to the metal components, hazardous, and difficult to handle; chelating acid was chosen as an alternative since it is known as a metal-friendly and able to dissolve carbonate and iron deposit. Treatment to address pump stuck situation was executed in March 2020. The chemical treatment was injected by pumping and circulating chelating solution from tubing to the annulus. ESP then soaked for 48-hours long.
The treatment has successfully revived the well. It produced with no significant issue for 8 months and even double the oil production. This successful treatment proves chelating technique is safer for ESP and able to regain well production. Significant cost saving up to 76,000 USD was realized by avoiding rig intervention and shortening time of well services. Detailed study, laboratory testing, treatment procedure, and further analysis are discussed in this paper.
Chelating acidizing is an uncommon acid system to stimulate carbonates and sandstone in our operating area. Since its successful performance during the trial, more acid campaign using chelating was conducted to enhance oil production. However, this acid system was never been tried as a solution treatment for pump stuck condition and the case of well XY-107 was the first time in the company's history.

Abstract
With advancing technology, PCB (Printed circuit board), one of the most important components of e-waste, has become a source of pollution due to an ineffective waste management system. This problem can be solved by converting PCB waste into a valuable product which will emerge to maximize the renewable energy supplies. In this aspect, co-pyrolysis is advantageous in both simple and successful in producing high-quality pyrolysis oil. In this paper, cotton stalk (CS) as biomass was used for co-pyrolysis with PCB. Slow pyrolysis of PCB, CS, and co-pyrolysis of PCB:CS (1:1) have been carried out for temperatures up to 500 \(℃\) in a fixed-bed reactor. The products of pyrolysis: oil was analysed by GC-MS and FTIR and gas had been analysed by GC. The results indicate that there is an increase in oil yield from 19.6% to 27.5 % by weight and phenol and phenolic compounds in oil of co-pyrolysis from 60.94–76.82% than literature available. As per authors knowledge co-pyrolysis of PCB:CS has been attempted first time and the products characterisation were found completely different than any other biomass co-pyrolysis with PCB.

Abstract
Background

Despite multiple attempts, there is still no effective HIV-1 vaccine available. The HIV-1 polymerase (pol) gene is highly conserved and encodes cytotoxic T-lymphocyte (CTL) epitopes. The aim of the study was to characterise HIV-1 Pol CTL epitopes in mostly sample pairs obtained during early and chronic stages of infection.
Methods

Illumina deep sequencing was conducted for all samples while Sanger sequencing was only performed on baseline samples. Codons under immune selection pressure were assessed by computing nonsynonymous to synonymous mutation ratios using MEGA. Minority CTL epitope variants occurring at \(\ge\)5% were detected using low-frequency variant tool in CLC Genomics. Los Alamos HIV database was used for mapping mutations to known HIV-1 CTL epitopes.
Results

Fifty-two participants were enrolled in the study. Their median age was 28 years (interquartile range: 24–32 years) and majority of participants (92.3%) were female. Illumina minority variant analysis identified a significantly higher number of CTL epitopes (n = 65) compared to epitopes (n = 8) identified through Sanger sequencing. Most of the identified epitopes mapped to reverse transcriptase (RT) and integrase (IN) regardless of sequencing method. There was a significantly higher proportion of minority variant epitopes in RT (n = 39, 60.0%) compared to IN (n = 17, 26.2%) and PR (n = 9, 13.8%), p = 0.002 and < 0.0001, respectively. However, no significant difference was observed between the proportion of minority variant epitopes in IN versus PR, p = 0.06. Some epitopes were detected in either early or chronic HIV-1 infection whereas others were detected in both stages. Different distribution patterns of minority variant epitopes were observed in sample pairs; with some increasing or decreasing over time, while others remained constant. Some of the identified epitopes have not been previously reported for HIV-1 subtype C. There were also variants that could not be mapped to reported CTL epitopes in the Los Alamos HIV database.
Conclusion

Deep sequencing revealed many Pol CTL epitopes, including some not previously reported for HIV-1 subtype C. The findings of this study support the inclusion of RT and IN epitopes in HIV-1 vaccine candidates as these proteins harbour many CTL epitopes.

Published: October 2021

Abstract

A biosensor based on the modified Kretschmann configuration is proposed here. The sensitivity of the conventional prism-based sensor using angular interrogation is low. To enhance the sensor's performance, layers of zinc sulfide (ZnS) and graphene have been deposited over the metal layer. The angular interrogation technique is used to analyze the performance of the sensor. The thickness of the Ag metal has been optimized. The thickness of the Ag metal is taken as 50 nm because minimum reflectance has been achieved. With the combinations of the four layers of ZnS and one graphene layer, the maximum sensitivity attained is 305o/RU. Performance parameters such as detection accuracy, FWHM, and quality factor of the sensor have been evaluated as obtained as 0.33 deg-1, 3.05 deg, 100.7 RIU-1, respectively. The proposed sensor has potential application in the field of biochemical and biological analyte detection.

Abstract
BackgroundAlcohol drinking during pregnancy is towering in spite of the well-established prove on its unfavorable pregnancy results and destitute child improvement. Despite such enormous consequences, there are limited data that explore about the extent of alcohol drinking and its associated factors among mothers during pregnancy in sub-Saharan Africa. ObjectiveThis study aimed to assess the prevalence and associated factors of alcohol consumption during pregnancy among pregnant mothers in sub-Saharan Africa. MethodA community based crossectional demographic and health survey was conducted from 2013 to 2017 among four Sub-Sahara African countries: Burundi, Ethiopia, Liberia and Zimbabwe. A two-stage stratified sampling technique was employed to select the participants. Multivariable Logistic regression analysis was used to identify factors associated with alcohol consumption during pregnancy. A p-value less than 0.05 and 95% confidence interval were used to declare statistical significance.ResultA total of 3,953 weighed sample of pregnant mothers were included in the study. The mean age of the participants was 27.3 (± 6.8) years with an age range of 15-49 years. The overall prevalence of alcohol use during pregnancy was 22.8% with (95% CI (21.5, 24)) and it was significantly associated with increased age (AOR=1.02, 95% CI (1.01, 1.04)), Muslim religion follower ( AOR=0.07, 95% (0.05,0.11), husband/partner’s educational status of primary (AOR=0.7 ,95% CI (0.55,0.84), secondary (AOR=0.53, 95% CI ( 0.41,0.7)) and higher (AOR=0.49 , 95% CI(0.31,0.8), being currently working (AOR=1.5,95% CI ( 1.09,1.55) , having ANC visit ( AOR=0.82, 95% C I(0.68,0.98) and increased gravidity ( AOR=0.93,95% CI( 0.86,0.99).Conclusion Alcohol drinking during pregnancy was high among pregnants in sub-Saharan African countries. Maternal age, religion, husband educational status, current working status of the mother, presence of ANC visit and gravidity of the mother were factors which have significant association with alcohol drinking during pregnancy. This calls a tailored behavior change intervention to reduce alcohol use during pregnancy. More emphasis should also be given for pregnant women with no ANC visit, lower gravidity, and an illiterate husband, currently working and Christianity followers.
