Authors: Nandi Nupur , Agarwal Ritika , Bajpai Garima 
Published: December 2021

Abstract
Background: The ongoing pandemic situation by a highly infective Covid-19 virus is a global health threat. Pregnancy related physiological changes of cardio- respiratory system and relative immunosuppression might cause more infectivity and worsening complications of this novel respiratory virus infection. Limited data availability on feto -maternal outcome of Covid 19 positive pregnant women necessitates the current study.Methodology: A prospective cohort study was conducted in a government designated level III Covid care hospital at Teerthankar Mahaveer Medical College & Research Centre to assess the feto-maternal outcome in Covid 19 RT- PCR test positive pregnant women delivered between April 2020 to September 2020. Mothers were evaluated in terms of asymptomatic status or predominant symptoms (fever, cough, sore throat, and breathlessness), complication if any including need for ventilatory support for extensive pneumonia, or mortality. Neonates were tested for presence of infection by RT-PCR test on day 2 & 5 of delivery, and also looked for any symptoms of the disease or it’s complication.Results: Total 33 women with Covid19 positivity delivered at term pregnancy in the said period of 6 months. The most frequent (45.45%) age group was 26 to 30 years. Asymptomatic Covid 19 positive cases were more (57.58%) prevailing over symptomatic patients. Fever was most frequent (33.33%) physical symptom. Emotional quotient was significantly affected by presence of anxiety amongst 36.36%. Caesarean delivery conducted maintaining all protocol in 60.6% women, but all were indicated for other obstetric reason. None of the mother had developed significant pneumonia or other complication. One case of maternal mortality noted, but was not related to Covid 19 infection. Vertical transmission was nil in our study and no neonate was affected by any complication.Conclusion: Course of disease was not different in pregnant women infected by Covid 19 virus in late pregnancy in comparison to non-pregnant adults. No case of vertical transmission noted, neither any neonatal morbidity nor mortality in present study, shows the importance of following optimum protocol. All pregnant women should be screened for Covid 19 infection in current scenario.

Published: December 2021

Abstract
We proposed a model for all-optical switching in a medium consisting of four-level vee-cascade atomic systems excited by coupling, probe, and signal fields. It is shown that, by changing the intensity or the frequency of the signal field, the medium can be actively switched between either electromagnetically induced transparency (EIT) or electromagnetically induced absorption (EIA), which has behavior of all-optical switching. As a result, a cw probe field is switched into square pulses by modulating the intensity or the frequency of the signal light. Furthermore, width of the square probe pulses can be controlled by tuning the switching period of the signal field. Such a tuneable all-optical switching is useful for finding related applications in optic communications and optical storage devices.

Published: December 2021

Abstract
Based on the simultaneous observation of fine particulate matter (PM2.5) and its chemical components in four heavy haze pollution episodes at 14 sampling sites in northeast China from 2017 to 2019, the formation and existence of sulfate (SO42-) and nitrate (NO3-) secondary contaminants under different stages of the pollution episodes, and different meteorological and emission conditions were compared. The results yielded three main findings. (1) Organic carbon (OC) was the most important component of PM2.5, followed by NO3-,SO42-,and ammonium (NH4+). Nitrate surpassed sulfate as the most important secondary inorganic component over the study period. (2) The significant increase in atmospheric OC, SO42-, and NO3-concentrations was an important reason for haze formation. Meteorological factors such as wind direction, wind speed, temperature (T), relative humidity (RH), and atmospheric oxidability played an important role in secondary pollutant formation. (3) There were two potential SO42- formation mechanisms. The first was the gas-phase reaction of the hydroxyl radical(OH·) leading to the oxidation of nitrogen dioxide (NO2) and sulfur dioxide (SO2),and high ozone (O3) concentrations. A high atmospheric oxidability and high winter Ts were very important for SO42- formation. The second mechanism occurred under neutral or weakly alkaline conditions when large amounts of SO2 could enter aerosol droplets, and NO2 was more likely to react in the aqueous phase with SO2 to increase the output of SO42-. Nitrate formation was may be mainly due to the homogeneous gas-phase reaction of OH· with NO2, SO2, and ammonia(NH3). The highest NO3 concentration was observed under mild winter Ts, high RH, high atmospheric oxidability (O3 and nitrous acid (HONO)), high NH3 concentrations, and suitable light conditions. The differences in SO42- formation between northeast China and other regions were mainly a result of the suppression of the aqueous reaction of SO42- due to the low T in winter and low-sulfur coal emissions, which resulted in the gas-phase oxidation process with the highest SO42- production capacity becoming an important process. However, the aqueous reaction process was the most common mechanism of SO42- production in northeast China.

Published: December 2021

Abstract
This work investigated As(V) removal from aqueous solutions using calcium alginate microspheres with encapsulated iron nanoparticles (FeNPs) in batch systems. The kinetic, equilibrium, and thermodynamic parameters of the adsorption process were evaluated. Adsorbents were characterized using Fourier Transform Infrared Spectroscopy, Scanning Electron Microscopy, and Zeta Potential techniques. The FeNPs were obtained by a simple and low-cost method and they were successfully encapsulated and uniformly dispersed over the microspheres' surface. Significantly fast adsorption kinetic rates were observed due to microspheres' particle size and FeNPs encapsulation. The chemisorption mechanism was recognized in both adsorbate-adsorbent systems. The As(V) isotherms data suggested that the process is associated with heterogeneous adsorption. Available sorption sites with different adsorption energies were related to the functional groups involved in removing As(V), such as hydroxyl and carboxyl groups. Significantly high adsorption capacities were obtained for both materials, suggesting they can be competitive compared to conventional adsorbents, even at low FeNPs concentrations. Besides FeNPs encapsulation enhancing arsenate removal, higher adsorption was obtained at slightly acidic pH values and, together with their small particle size, suggests that the microspheres have a great potential to be used as arsenate adsorbents in the water treatment for human consumption.
Impact of planning horizon on water distribution network design
Authors: Zeng F. , Li K. , Li X. , Tollner E. W. 
Published: December 2021

Abstract
The continuous expansion of the Water Distribution Network (WDN) makes its design a dynamic process performed within many planning horizons. An appropriate planning horizon is important to save costs and avoid over-design. Typically, a master plan is practiced around every 20 years. The complexity of WDN and computational demands have prevented a full network study of the impact of planning horizons on system cost and efficiency. In this paper, a dynamic network model was employed to simulate the growth of WDN under different growth patterns (exponential and linear) and planning horizons to explore the optimum planning horizon under different interest rates. It is found that the choice of the optimum (i.e. least costly) planning horizon is sensitive to the interest rate. For both growth patterns, a shorter planning horizon is favored with higher annual interest rates while a longer planning horizon is favored with lower rates. With the same interest rate, exponential growth pattern generally favors a shorter planning horizon than a linear growth pattern due to more excess capacity provided at the beginning of the study period. The optimum planning horizon is longer than 20 years when the interest rate is lower than 3.0% for linear growth or 2.0% for exponential growth.

Published: December 2021

Background:
The novel severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), which belongs to the family Coronaviridae, is the cause of COVID-19
infection. Its outbreak was declared a pandemic on March 11, 2020. COVID-19 does not involve the respiratory system solely, but other systems
were also noted to be affected, including the endocrine, cardiovascular, and gastrointestinal systems. Several case reports and series have been
published regarding SAT related to COVID-19 infection, yet management and clinical outcomes of the disease have not been discussed in detail.

Methods:
This is a systematic review of cases that have been reported to have subacute thyroiditis induced by COVID-19 infection. A systematic search was
conducted throughout multiple databases, including PubMed, Google Scholar, and MeSH network.

Results:
The total number of reported subacute thyroiditis cases attributed to COVID-19 is 24. There was a female predominance (18 females and 6 males)
with a female to male ratio of 3:1. Ages ranged from 18 to 69 years (mean = 38.67). Twenty-four symptoms related to thyroiditis were reported,
the most common of which being neck pain (95.83%, n=23), palpitations (79.17%, n=19), and fever (66.67%, n=16). The outcome was complete
resolution in 70% of cases.

Conclusion:
The endocrine complications of COVID-19 and their management have been disregarded by most as they are rare. Our knowledge of COVID-19
and its complications is growing rapidly. More favourable outcomes were linked with the use of corticosteroid therapy. Until larger studies can be
conducted, the management of SAT caused by COVID-19 remains to be based on each individual case. However, the treatment regimen should
include corticosteroid therapy.

Published: December 2021

Background:
The transplant patients should be considered a main high-risk population
during the COVID-19 outbreak due to the use of immunosuppressive regimens and comorbidities.

Objective:
This study aimed to evaluate the possibility of COVID-19 transmission by liver transplantation
from a donor with a late complication of COVID-19 to the recipients.

Method:
This descriptive study was conducted on all the recipients of liver transplantation who
had an acute liver failure or were the models for the End-Stage Liver Disease (MELD) higher than
20.

Results:
In general, 36 liver transplantation was performed during the study period. Out of these patients,
only 14 cases (deceased donors) had hemorrhagic cerebrovascular accidents, and other
donors died of trauma (n=7) and anoxia (n=15). All patients showed negative results for polymerase
chain reaction (PCR) (two negative 24 h PCR), whereas their high-resolution computed tomography
(HRCT) test revealed that they had previously lung involvement with COVID-19 as the
late complication of the disease.

Conclusion:
This study supports the safety of continuing donation and transplant process during
the outbreak even the transplant donor be infected previously with the COVID-19, which is reinforced
by other similar pieces of evidence.

Published: December 2021

:By-products from the food sector now have a wide range of applications. Low-cost raw materials, followed by low-cost goods, are regarded as one of the sectors’ top goals. Because of its economic relevance, reduced price, and nutrients such as protein, fiber, carbs, and antioxidants, oilseed cakes (OCs) have found a desirable place in livestock and poultry feed. Furthermore, because the cake has the same desirable nutrients, its usage in the food business is unavoidable. However, its use in this sector is not simply for nutritious purposes and has it has different impacts on flavor, texture, color, and antioxidant qualities. Therefore, as a result of its desirable qualities, the cake can be more useful in extensive applications in the food business, as well as in the manufacture of supplements and novel foods. The current review looks at the reapplications of byproducts obtained from oilseeds (soybean, sunflower, sesame, canola, palm kernel, peanut, mustard, and almond) in the food sector in the future. Furthermore, allergenicity, toxicity, antinutritional compounds, and techniques of extracting cakes from oilseeds have been discussed.
Multi-objective Optimization of High-speed Solenoid Valve for Biodiesel
Electronic Unit Pump
Authors: Gu Yuanqi , Fan Liyun , Zhang Jianyu , Bai Yun 
Published: December 2021

Background:
A larger response delay of a high-speed solenoid valve will cause inaccurate
fuel injection timing and imprecise cycle injection quantity, resulting in diesel engine emission
and increased fuel consumption.

Objective:
Biodiesel as an ideal alternative fuel has exceptional advantages in energy conservation,
emission reduction, and low-carbon environmental protection; however, matching with Electronic
Unit Pump (EUP) and its impacts on solenoid valve operation need to be further studied.

Methods:
In the present work, a numerical model of EUP fueled with biodiesel was established in
an AMESim environment, which was validated by the experiment. Then, combined with the Design
of Experiments (DOE) method, key parameters influencing the solenoid valve response delay
were predicted: armature residual air gap, spring preload, poppet valve half-angle, valve needle
diameter, and poppet valve diameter.

Results:
taking the response delay time of solenoid valve as targets, multi-objective optimization
model for high-speed solenoid valve was established using NSGA-II (non-dominated sorting genetic
algorithm-II) genetic algorithm in modeFRONTIER platform.

Conclusion:
The optimized results showed that the delay time of the solenoid valve closing is
reduced by 6%, the opening delay time is reduced by 20.8%, the injection pressure peak is increased
by 1.8MPa, which is beneficial to accurate injection quantity and the application of biodiesel
in diesel engines.
Evaluation of Childbirth Self-Efficacy in Pregnant Women with
Variables: A Systematic Review and Meta-Analysis
Authors: Demirci Ayse Deliktas , Kochan Merve , Kabukcuoglu Kamile 
Published: December 2021

Objective:
The present study aims to examine childbirth self-efficacy
levels with potential moderating variables.

Methods:
The systematic searches were conducted in nine databases in July
2019. The PRISMA checklist was used. The quality of studies was evaluated by
two researchers. The random-effect model was used in the present meta-analysis.
The heterogeneity tests and moderator analyses were performed. There were 18
eligible articles.

Results:
Results indicated that childbirth self-efficacy levels do not change based
on parity (Q = 0.784, p = 0.376 for efficacy expectancy, Q = 0.190, p = 0.663 for
outcome expectancy). The between-study variance was not significant for subdimensions
of CBSEI (Qb = 1.531, p = .216), which means no significant difference
between OE and EE levels was found. The between-study variance was not
significant for OE levels (Qb = 0.333, p = .847), which means no significant difference
was found between Outcome-AL, Outcome-SS, and OE-16. The moderator
analysis, including Efficacy-AL, Efficacy-SS, and EE-16 presented a higher
pooled mean score for EE-16 (111.56; 95% CI = 98.66 to 124.46). However, the
between-study variance was not significant for EE levels (Qb = 4.240, p = .120).
Despite the moderator analysis, the finding of high heterogeneity suggests the
need for further studies which examine the concept of childbirth self-efficacy
with additional variables.

Conclusion:
The study presents that childbirth self-efficacy levels do not change
based on parity, stages of labor and subdimensions of CBSEI. Researchers need
to examine the concept of childbirth self-efficacy with new variables for further
clarify of concept.
Analisis Shariah Compliance Praktik Murabahah Lil Aamir Bisy-Syiraa' pada Bank Syariah di Indonesia
Authors: Iskandar Azwar , Wijaya Hendra , Aqbar Khaerul 
Published: December 2021

Abstract: This research aims to analyze the extent of the practice of murabahah in sharia banking Indonesia according to the concepts and rules of sharia, jurisprudence, and fatwa (shariah compliance). The study uses a qualitative-descriptive approach with a critical study method and library research. The results showed that the practice of murabahah in sharia banking has not fully fulfilled the rules in shariah compliance. Among the irregularities that have occurred to shariah compliance: (i) the murabahah agreement is directly agreed between the sharia bank and the customer, while the goods have not belonged to the bank and have not been accepted (al-qabd) with the result that the contract becomes void; (ii) the designation of the deputy by sharia bank in the murabahah lil aamir bisy-syiraa' is feared falling on the riba, namely as ‘hilah’ for debt with interest; (iii) the practice of the murabahah agreement may fall on the type of double contract (al-'uquud al-murakkabah) which is prohibited if the agreement between the customer and the bank is binding and there is no right to vote between the parties (khiyar); (iv) in its practice, sharia banks do not take profit based on the ra’sulmāl, but from the money incurred by the bank; and (v) in the event of a guarantee position, the sharia bank lays it as a necessity. Abstrak: Penelitian ini bertujuan untuk menganalisis sejauh mana praktik murabahah di perbankan syariah Indonesia telah berjalan sesuai konsep dan aturan syariat Islam, baik berdasarkan nas-nas syariat, batasan-batasan fikih, maupun fatwa-fatwa DSN-MUI (shariah compliance). Penelitian ini menggunakan metode pendekatan kualitatif-deskriptif dengan metode studi kritis dan riset kepustakaan (library research). Hasil penelitian menunjukkan bahwa praktik murabahah pada perbankan syariah belum sepenuhnya memenuhi aturan dalam syariat (shariah compliance). Di antara penyimpangan yang terjadi terhadap kepatuhan syariah (shariah compliance): (i) akad jual-beli murabahah langsung disepakati antara pihak bank syariah dan nasabah, sementara barang belum menjadi milik bank dan belum diterima (al-qabd) sehingga akad tersebut menjadi fasid (batal); (ii) penunjukan wakil oleh bank syariah dalam akad murabahah lil aamir bisy-syiraa’ dikhawatirkan terjatuh pada syubhat riba, yaitu sebagai hilah (rekayasa) atas hutang dengan bunga; (iii) praktik jual-beli dengan akad murabahah dapat terjatuh pada jenis akad berganda (al-‘uquud al-murakkabah) yang terlarang jika perjanjian antara nasabah dan bank bersifat mengikat dan tidak ada hak khiyaar (memilih) antara kedua belah pihak; (iv) dalam praktiknya, bank syariah tidak mengambil keuntungan berdasarkan besaran dari ra’sulmāl, namun dari besaran uang yang dikeluarkan oleh bank; dan (v) dalam hal kedudukan jaminan, bank syariah menetapkannya sebagai suatu keharusan.
