Authors: Bansal Bharat Naresh , Singh Navjot 
Published: November 2021

Abstract
Explosive increase in internet services put peer pressure on conventional band grid (1530–1570 nm) and therefore L-band wide wavelength grid is required to cater the ever-increasing demands. In this work, accentuation is given to enhance the gain flattening of ultradense (25 GHz) L-band WDM system using single stage EDFA amplifier when ultralow power is launched from 16 and 32 channels. High gain and gain flattening is achieved by incorporating three fiber Bragg gratings (FBGs) for amplified spontaneous noise reinjection. Maximum Amplified spontaneous emission (ASE) is emerged at 1565 nm for the 1575.69–1579 nm input wavelengths (16 channels) and 1572.58–1579 nm (32 channels) at −55 dBm ultra low carrier powers. To optimize different parameters of L-band EDFA, different physical parameters such as core radius, EDF link lengths, and launched powers are varied, and results are analyzed in terms of lateness. Maximum gain is found out to be 34.12 dB at optimal physical parameters of the EDF with gain flatness of ±0.45 dB in case of 16 channels and ±1.41 in case of 32 channels.
Manual metal arc welding of dissimilar 30MnB5 and S 235 low alloyed steels for agricultural applications
Authors: Çevik Bekir 
Published: November 2021

AbstractIn agricultural mechanization industry, different types of materials are assembled with each other to establish agricultural machine systems. However, the necessity of joining dissimilar materials used in the same machine system may cause some problems. Joining two different materials by welding and selecting the most appropriate weld metal (electrode) for this is a very difficult problem. The increasing importance of the economic factors in today’s industry requires both the use of dissimilar materials in agricultural mechanization and the production of longer-lasting agricultural machines, thus making it necessary to use dissimilar steels in agricultural mechanization systems. Therefore, it is important to apply a welding process to dissimilar steels used in agricultural mechanization. In this study, 30MnB5/S235 steel pairs were joined by the manual metal arc welding (MMAW) method using different covered electrodes. In order to determine the mechanical properties of the welded samples, hardness, bending, and impact tests were carried out. In addition, visual inspection to the weld seams, liquid penetrant testing, and metal-lographic examinations to determine the microstructural properties were conducted. As a result of the microstructure studies, structures such as grain boundary ferrite, Widmanstätten ferrite, acicular ferrite, bainite, and martensite were determined in the weld metal and HAZs. As a result of the hardness test, the highest hardness values were determined in HAZs on the side of 30MnB5 steel. As a result of the bending test, the highest mechanical properties were obtained in the weld seams made with basic flux-cored wire. As a result of the notch impact test, the highest mechanical properties were obtained in the weld seams made with basic flux-cored wire, after the base metals.

Published: November 2021

Abstract
An asymmetric alumina ceramic membrane was prepared by secondary dip coating. The influence of different dispersants and dip coating parameters on the microstructure of the membrane separation layer was explored. Meanwhile, the pure water fluxes of the membranes with various microstructures were also studied. The results show that a separation layer with a defect-free thickness of 16.5 μm and high surface flatness can be obtained when using polycarboxylate as a dispersant and twice dip coating within 2 s + 1 s and the pure water flux of an asymmetric membrane up to 1153 L × m-2 × h-1 × bar-1. The present work provides a simple and effective method for controlling the morphology and permeation performance of an asymmetric alumina membrane.

AbstractSpatial division multiplexed optical transmission over a multi-ring-core orbital angular momentum (OAM) fibre is reported for the first time. The seven cores in the fibre each supports OAM modes belonging to mode groups (MGs) of topological charge |l| = 0–4. The MGs of |l| = 1–4 each contains four near-degenerate OAM modes that carry the combinations of opposite orbital and spin angular momenta. The weak coupling between these higher-order MGs as well as between the cores enables the simultaneous transmission of 56 OAM mode channels (two MGs per core of the topological charges |l| = 2 and 3) over the 60-km span, while only requiring modular 4 × 4 multi-input multi-output (MIMO) signal processing to equalize the mixing among the four mode channels in each MG that are strongly coupled – a feature that also minimizes the number of filter taps. The mode channels are launched using seven-core single-mode fibre fan-in devices, with the light in all seven cores converted into OAM modes via specially designed plates that carry seven off-axis-compensated phase masks matching the hexagonal configuration of the multi-core fibres. Each mode channel carries 10 WDM wavelengths, equivalently aggregating to a capacity of 31.4 Tbit/s (net 25.1 Tb/s) and a spectral efficiency (SE) of 62.7 bit/s/Hz (net 50.2 bit/s/Hz) with 28-GBaud QPSK modulation per data channel.

Optimization of Kiel geometry for better recovery factor in high temperature measurement in aero gas turbine engine
Authors: George Benny , Muthuveerappan Nagalingam 
Published: November 2021

Abstract
During gas turbine engine testing, steady-state gas-path stagnation temperatures and pressures are measured in order to calculate the adiabatic efficiencies of the major turbomachinery components. These measurements are carried out using fixed intrusive probes, which are installed at the inlet and outlet of each component. The overall uncertainty in calculated component efficiency depends on the accuracy of discrete point pressure and temperature measurement. High accuracy in measurement and prediction of measurement errors has become increasingly important if small gains in component performance needs to be achieved. The recent trend is to predict component efficiencies within ±1–2%. The present work covers different Kiel designs that have been developed in a response to this demand based on a MATLAB code and experimental evaluation. A parametric study has been carried out by varying the two most critical parameters viz. Ae/Ab ratio and L/D ratio to optimize the Kiel design. These design changes will allow measurements to be made with minimum possible errors and efficiencies to be calculated more accurately over a wider range of conditions inside a low bypass turbofan gas turbine engine.
A New Apparatus for Installing Distributed Optical Sensors onto Uniaxial Compression Test Specimens to Measure Full-Field Strain Responses
Authors: Hegger Shawn , Vlachopoulos Nicholas , Diederichs Mark S. 
Published: November 2021

Abstract
The uniaxial compressive strength (UCS) test is a key tool used by the geotechnical industry to determine the strength and stiffness behavior of intact rock. A fundamental procedure in the process of these experiments is strain response measurement. The standard method of measuring UCS test strain response is to use discrete strain measuring devices such as extensometers or electric strain gages, or both, at the mid-height of a specimen. However, by using a novel technique of integrating distributed optical strain sensing with UCS testing, a high-density full-field strain response of UCS specimens can be measured. This article presents a novel device that can be used as a turnkey solution for installing optical strain sensors to the exterior of UCS specimens for the benefit of measuring full-field specimen strain during UCS testing.

Published: November 2021

Objective
Recessive WFS1 mutations are known to cause Wolfram syndrome, a very rare systemic disorder. However, they were also found in non-syndromic diabetes in Han Chinese misdiagnosed with type 1 diabetes (T1D), a molecular cause that appears to be considerably more common than the fully expressed syndrome. We aimed to better define the incidence and clinical features of non-syndromic diabetes due to recessive WFS1 mutation.

Design
We analyzed the genotype and phenotype of 320 consecutive incident Chinese pediatric diabetic patients diagnosed from 2016 to 2019 to search for non-syndromic diabetic cases due to recessive WFS1 mutation.

Methods
A cohort of 105 pancreatic autoantibody-negative patients were recruited for exome sequencing. All patients tested positive for pathogenic diallelic WFS1 mutations were examined for phenotypic features (fundoscopy, audiogram, and urine density).

Results
We found three cases of non-syndromic diabetes due to recessive WFS1 mutations (incidence = 0.94% (95% CI: 0.25–2.7%)). All three cases only had mild diabetes when diagnosed. All patients had well-conserved fasting C-peptide when diagnosed but one of them progressed to T1D-like insulin deficiency. In addition, we found a fourth case with previously undetected features of Wolfram syndrome.

Conclusions
Non-syndromic diabetes due to WFS1 mutation may be common among Chinese pediatric patients with diabetes. It is important to differentiate it from other maturity-onset diabetes in the young subtypes with similar phenotype by molecular diagnosis because of different prognosis and, potentially, therapy.

Published: November 2021

Present study was undertaken for assessment of spatial characteristics of road traffic noise at varying intervals viz early morning (8-9 am), late morning (11-12 pm), afternoon (2-3 pm) and evening (6-7 pm) time at ten important locations (near school building) of G. T. Road which is passing through the Burdwan town. Digital noise meter was used for recording the traffic noise and noise contour map was constructed by using Geographical Information System (GIS). The recorded data revealed that the highest and lowest average noise 67.1 dB (A) and 86.9 dB (A), respectively. The results revealed that the performance of the CRTN model in both afternoon and evening time for predicting noise level near school building with a coefficient of determination (R2) are 0.536 and 0.544 and a mean difference of - 1.19 dB (A) and - 0.48 dB (A) between the measured and predicted values respectively. Similarly, Pearson statistics also revealed the strong correlation between measured and predicted noise level at afternoon (r = 0.732, p < 0.016) and evening time (r = 0.744, p < 0.014). However, the predicted traffic noise during early morning and late morning hour are less than 0.5. These low values are due to irregular traffic speed, traffic density and irregular building height are the appropriate reasons for low accuracy in predicting model. Finally, it may be suggested that CRTN model can be a decision tool for predicting equivalent noise level in the city like Burdwan.
Formation of extracellular traps by circulating neutrophils and monocytes in rheumatoid arthritis patients: a study of new citrullinated autoantigen

Published: November 2021

Detection of subcellular structures containing typical citrullinated rheumatoid autoantigens in a single compartment presents a special interest, due to importance of anticitrulline autoantibodies for the autoimmune response in RA. Neutrophil and monocyte extracellular traps (NETs and ETs, respectively) may be considered such candidate structures. Our objective was to assess ability of blood neutrophils and monocytes from RA patients to generate NETs and ETs spontaneously and after in vitro induction.32 patients with verified RA and 30 healthy volunteers as controls were included into the study. Circulating neutrophils and monocytes were isolated with one-step density gradient centrifugation using three layers of ficoll-amidotrizoate gradient. Composition of isolated cellular fractions, their viability, and non-specific activation were evaluated microscopically using Trypan Blue exclusion test, as well as Nitro-Blue Tetrazolium test. The NETs were induced by phorbol-12-myristate-13-acetate, and ETs by bacterial LPS. Spontaneous and induced formation of extracellular traps was assessed using fluorescence microscopy. Neutrophil and monocyte fractions contained minute percentages of impurities and low extents of activated and dead cells. Spontaneous NET and ET formation in RA patients was significantly increased comparing to healthy controls. Neutrophils from ACPA-positive RA patients were found to have higher frequency of NET formation, compared to ACPA-negative RA patients. The monocytes did not demonstrate such differences between these subgroups. There were no substantial morphological differences in NETs and ETs patterns between the individuals from both groups. Induced extracellular trap production in RA was significantly higher compared to healthy controls. The level of myeloperoxidase-specific fluorescence in ETs was considerably lower than in NETs. NETs could probably be considered as a source of citrulline autoantigen participating in autoantibody production and stimulation of inflammatory autoimmune responses in RA, whereas ETs may play less important role in this process.
Role of antimicrobial peptide DEFB126 mutation in pathogenesis of male idiopathic infertility

Published: November 2021

Male infertility is a multifactorial disease, and elucidation of etiopathogenetic mechanisms of its progression is a topical issue. High percentage of the “idiopathic infertility” diagnosis is largely cased by inability to establish etiology of decrease in reproductive spermatic function. Mutation of в-defensin DEFB126 gene is supposed to affect the fertilizing ability of spermatozoa at different levels: it may decrease their ability to migrate through the cervical mucus and reduce binding capacity to epithelial layer of upper female reproductive tract, and it may also increase susceptibility for infections of reproductive tract, due to impairment of local protective function of defensins. Thus, the aim of the present study was to examine possible role of rs11468374 gene polymorphism of the DEFB126 gene in pathogenesis of male idiopathic infertility. Patients and methods: The group of patient with decreased fertility included 54 male subjects, ages 34 to 42, with a control group of 19 ejaculate donors without acute or chronic disease aged 28 to 36. The indicators of sperm motility in the Moscow population were compared with individual levels of DEFB126 gene expression, as well as with estimated distribution frequency of rs11468374 alleles and genotypes among the subjects.As compared with the control group, the infertile patients exhibited a more than seven-fold reduction of DEFB126 gene expression. Analysis of distribution frequency for alleles and genotypes rs11468374 polymorphic marker of the DEFB126 gene revealed that the mutant allele is detected almost twice as often in males with infertility, as compared with control group. No cases with the DEFB126 del/del genotype were found among the control group, in contrary to 16.1% in the group of patients. The patients with DEFB126 del/del genotype exhibited 5.2-fold reduction of sperm motility. Thus, the data obtained may be used to extend our knowledge on the pathogenetic mechanisms of male idiopathic infertility and to improve techniques for its diagnostics, as well as to provide personalized approach to the treatment of male reproductive disorders. The association between carriage of del mutant allele and decreased level of sperm motility suggests a role of this polymorphism in pathogenesis of male infertility. A general decrease in the level of DEFB126 gene expression in the patients affected by infertility also presumes a contribution of defensin 126 to pathogenesis of the disorder.

Staphylococcus aureus is a common health problem occuring as an important nosocomial pathogen, causing urinary tract infection, surgical site, blood stream and soft tissue infection. The aim of this research was conducted to determine MRSA and VRSA from the pus samples of admitted patients.The aim and objective of study was to isolate the resistance pattern of Staphylococcus aureus in pus samples and their AST. A total of 158 positive culture Staph aureus were taken from pus samples for the study during December 2019 - October 2020. Samples were cultured on Blood and MacConkey agar then incubated at 37C for 24 hours. The modified Kirby Bauer's disc diffusion method was used to test antibiotic sensitivity of staphylococcus isolates. In total of 158 positive culture of Staphylococcus aureus, 66 (41.7%) were found to be MRSA and 4 (2.5%) were found to be VRSA. Out of 158 Staph aureus, 146 (92.4%) were resistant to Penicillin, followed by Amoxycillin 140 (88.6%), Ampicillin 139 (87.9%), Erythromycin 91 (57.5%), Cefoxitin 66 (41.7%), Gentamycin 56 (35.4%), Amikacin 52 (32.9%) and Teicoplanin 37 (23.4%).: An antibiotic policy and screening of susceptibility patterns of MRSA may help in reducing the prevalence rate of MRSA and antibiotic resistance. To stop its spread to the population, it is very important to eliminate MRSA colonization in patients and health care workers. Accurate treatment helps to reduce the rate of morbidity and improvement of patient’s outcome.
