Published: July 2023

Abstract
Urbanization has led to one of the most important climatic issues i.e., the Urban Heat Island (UHI) phenomenon. In Chennai Metropolitan Area (CMA), the overall distribution of the green cover has gradually succumbed to urbanization whereas the temperatures have soared by 1.3 deg C in the past six decades. Urban vegetation provides shade and protects the buildings from direct solar exposure, thus reduces the UHI. Further, it also sequester large quantities of carbon, reduce storm water runoff and function as noise filters and pollutant traps. In comparison with the international UHI studies, the studies concerning Indian UHI are limited. Hence, the aim of the current research work is to understand the seasonal relationship between Land Surface Temperature (LST) and the Normalised Difference Vegetation Index (NDVI) of CMA using LANDSAT 4, 5, 7 and 8 images captured during the years 1988, 1991, 1996, 2000, 2008, 2013 and 2016. The results are discussed under three parts namely, Part-A, Part-B, and Part-C. Part-A results infer that the CMA is covered predominantly by minimum LST values (9 deg C to 25 deg C) and maximum LST values (25 deg C to 50 deg C) during Monsoon and Summer/Post-Monsoon seasons, respectively. The mean LST of the CMA is between 18 deg C to 31 deg C throughout the year. In Part B analysis results, the study establishes a moderate seasonal correlation between LST and the NDVI values (r-values between -0.2648 and 0.3604). According to Part C results, ‘High Vegetation’ (NDVI values 0.5 to 1) has a significant role in maintaining the average LST during all four seasons. Further, it also has the potential to reduce the LST values during the summer season in CMA. However, due to a moderate correlation, the urban vegetation may reduce the LST value only as an outcome of reducing the rest of the UHI contributors.

Published: July 2023

Abstract
A tropical Chennai city, is already enduring heat stresses in its urban areas and is extremely vulnerable to temperature rise. Furthermore, Chennai continues to expand, thus the need to conduct research and make informed decisions on sensible strategies and regulations on how to construct and with what to construct attains much significance in recent times. One of the major contributors to the urban heat is the materials used on the surfaces of the urban form. The current paper assesses and demonstrates the performance of two wall materials – Clay Brick and AAC, usually utilized in urban developments within the context of an optimal urban morphological region. This is accomplished by making a compact mid-rise urban form of residential typology and utilizing ENVI-met 4.0 and re-creating the outdoor microclimatic conditions with AAC and Clay Brick walls. The urban form created with the Clay brick walls are found to be cooler by 0.010°C. Compared to daytime, at night time, the outside air temperature with clay brick walls and AAC dividers are cooler respectively. This investigation additionally discovered that a huge distinction to outside air temperature for studied urban form structure can be made by expanding the Sky View Factor (SVF), contrasted with an adjustment of material. The understandings from this study can be expanded and be applied productively to impact changes in Urban development guidelines.

Abstract
In the process of looking for ways to diversify the implementation into the production of secondary raw materials, a laboratory experiment was performed, the purpose of which was to determine whether the product of deep processing of corn, liquid corn extract, is suitable as a source of nutrients for seed germination. For this experiment, a winter cereal fodder crop was chosen - triticale (variety Tikhon). In a solution of corn extract with a concentration of 3 ml/l, triticale showed the best indicators of germination energy and germination compared to the control, which provides a perspective to study the application of this raw material as a natural biostimulator or a component of organic biofertilizer. According to biometric indicators, the seeds of winter triticale showed themselves better in the variant with a concentration of corn extract of 3 ml/l. In the variant with a concentration of corn extract of 5 ml/l, inhibition along the length of the roots is noticeable. The length of the sprout in two experimental variants is higher than in the control.

Abstract
Sowing is the most important agrotechnical operation, on which the yield directly depends. With the nested method of sowing soybeans, better illumination is achieved, thanks to which plants develop the root system and aboveground parts better, which contributes to a high attachment of the lower beans on plants and reduces losses during harvesting. A seeding apparatus for nest sowing has been designed and manufactured, taking into account the physical and mechanical properties and dimensional characteristics of soybean seeds. Field studies of the nested method of sowing soybeans were carried out in the farm “Niva” of the Tambov region, according to the results of which, taking into account the humidity and weight of 1000 seeds, the biological yield was calculated. With the nested method of sowing. on the experimental plot, a yield of more than 4 t/ha was obtained, which is 0.4% more than with continuous sowing on the control plot, despite the 2-fold increased seeding rate on it. The height of attachment of the lower beans on the plants of the experimental plot averaged 15 cm, on the control plot the height of attachment of the lower beans was 10 cm.

Changes of soil organic matter stock in meadow ecosystems in the south of Western Siberia
Authors: Yakutin M V , Yu Anopchenko L 
Published: July 2023

Abstract
The study was conducted on the Baraba plain in the southern part of Western Siberia. Soil samples in meadow ecosystems that are at different stages of succession after drying of the lake bottom were analyzed. The conducted research allowed us to establish that the content of soil organic matter and microbial biomass (the active part of soil organic matter) in successional ecosystems formed in the floodplain of the drying salt lake gradually increases and in the last stages of development reaches the values of zonal chernozem soils. The process of accumulation of carbon stocks of humus and microbial biomass slows down against the background of a high concentration of salts in individual horizons of young soil profiles. This may be the reason for the revealed pattern, according to which the main carbon stock of humus and microbial biomass are concentrated in the upper (0-10 cm) layer of the emerging soils. This is especially noticeable at the very first initial stage of soil development and the next stage of the salicornia community (Salicornia perennans). In the last stages of succession, solonetz and chernozem-meadow soils are formed under meadow ecosystems. The carbon stock of humus and microbial biomass at these stages of soil development significantly increase against the background of active processes of reducing the amount of salts in the profiles of meadow soils. And only at these last stages there is a significant increase in carbon stocks of humus and microbial biomass in a layer of 10-20 cm.
The last Pleistocene glaciation, gaps in the bird areas of Eastern Siberia and their role in increasing the species diversity of its territory during periods of sharp climate warming
Authors: Mel’nikov Yu I 
Published: July 2023

Abstract
Based on many years of work (1968-2022) and the analysis of special literature, the main features of the modern avifauna of Eastern Siberia and its relationship with Pleistocene glaciations and the climate of the previous epoch are shown. The eastern regions of Russia and the adjacent more southern large mountain systems were characterized by mountain-valley glaciations in the Pleistocene. As a result, up to the Himalayas, the continuous ranges of birds of this period were torn into two parts, and, taking into account the very complex terrain of the territory, into a larger number of isolates. Gaps in bird ranges caused intensive speciation and, in comparison with the previous period, to the formation of increased diversity. Modern climate warming, especially pronounced in Eastern Siberia, has led to the intensive movement of birds to the north, as well as the formation of western and eastern bird settlement flows. As a result, the total diversity of the species composition of birds in Eastern Siberia increased by 116 species (23.6% of the original diversity). The basis of the new species are birds whose habitats were torn apart during the last Pleistocene glaciation. After the discontinuities of the ranges, the tendency to the formation of new species is clearly visible in forest and mountain bird species. In waterfowl and waterfowl, they often did not lead to the formation of new species. This is due to the fact that coastal birds often had a common range far in the south of Asia, where the overall climate cooling was the least. Currently, some species have already formed extensive zones of intergradation of the habitats of closely related species, and many have a clear general trend towards the development of this process. Consequently, mountain-valley glaciers dramatically increased the diversity and isolation of habitats and increased the intensity of speciation of birds based on new geographical isolates. Undoubtedly, prolonged cooling and warming of the climate in a complex and diverse geographical environment are environmental factors of the evolutionary process.

Features of the dynamics of species ranges of some insect species in Transbaikalia in modern climatic conditions
Authors: Korsun O V 
Published: July 2023

Abstract
Over the past decades, a significant number of cases of invasions and expansions of the ranges of insects belonging to various taxa have been noted in Transbaikalia. Among them, one can single out both temporary, known for their habitation (including mass ones) only in certain years, and those that persist for a number of years and are examples of the successful expansion of species ranges. Cases of rapid expansion of the ranges of several species into new territories have also been noted. This can be explained by the tendency of the species to long-distance migrations or the ability to spread passively with the help of humans. For other species, the most acceptable hypothesis is the influence of climate change, which makes new territories more accessible.

Published: July 2023

Abstract
The article presents the results of studying the degree of destruction of phycocyanin in the composition of the protein module under various pasteurization modes. The objects of the study were: dry sodium caseinate with a mass fraction of protein 85%, dry whey protein concentrate with a mass fraction of protein 80% in dry matter, phycocyanin extract containing 42.7 wt.% phycocyanins. 1% aqueous solutions were prepared from each object. Sorption of phycocyanin by the protein matrix was carried out by combining an aqueous solution of 1% phycocyanin with a 1% aqueous solution of protein in a ratio of 1:1, and thermostated at a temperature of (28.0 ± 0.5)°C for 60 min. The prepared modules were pasteurized under the following conditions: 30 minutes at 60°C, 2 minutes at 75°C and 0.5 minutes at 95°C. The concentration of phycocyanin in the samples was determined by the spectrophotometric method. Under the experimental conditions, spectrophotometry revealed a tendency to destruction of phycocyanin during pasteurization under the studied temperature conditions. It has been established that milk proteins to some extent can have a thermoprotective effect on phycocyanin. The greatest effect of preserving phycocyanin was achieved in the protein module with sodium caseinate after sample pasteurization at 60°C.

Abstract
One of the ways to increase productivity of plowing unit is to meet the conditions of stability of the implement’s stroke at the least frictional forces of plough from pressure on the bottom and walls of the furrow. The direction of the traction line in the horizontal plane has a great influence on the resistance of the plough and the stability of its movement. The purpose of the research is to substantiate the optimal modes of operation of a tillage unit in the performance of technological operations. The laws of physical-mechanical and technological properties of soil were used in the analysis of working processes of agricultural machinery operation. Calculations were made to determine the tractor gauge for aggregating ploughs with different numbers of bodies and their working widths: the less hulls plough - the greater the pressure force, with 4 hulls the efficiency increases smoothly to 60% - 80%; with multibody ploughs (12 hull) efficiency can to 100%. The plow manufacturers should place the pull point at a distance from the center line towards the furrow by an amount equal to 1/3 of the length from the center of resistance to the pull point. Provided that plowing in the furrow: the track width of tractors when working with 1-4 body plows should be 0.65 … 0.95 m, when aggregating with plows from 5 to 14 bodies - 1.10 … 2, 69 m.

Published: July 2023

Abstract

Objectives
To validate a large next-generation sequencing (NGS) panel for comprehensive genomic profiling and improve patient access to more effective precision oncology treatment strategies.

Methods
OncoPanScan was designed by targeting 825 cancer-related genes to detect a broad range of genomic alterations. A practical validation strategy was used to evaluate the assay’s analytical performance, involving 97 tumor specimens with 25 paired blood specimens, 10 engineered cell lines, and 121 artificial reference DNA samples.

Results
Overall, 1107 libraries were prepared and the sequencing failure rate was 0.18%. Across alteration classes, sensitivity ranged from 0.938 to more than 0.999, specificity ranged from 0.889 to more than 0.999, positive predictive value ranged from 0.867 to more than 0.999, repeatability ranged from 0.908 to more than 0.999, and reproducibility ranged from 0.832 to more than 0.999. The limit of detection for variants was established based on variant frequency, while for tumor mutation burden and microsatellite instability, it was based on tumor content, resulting in a minimum requirement of 20% tumor content. Benchmarking variant calls against validated NGS assays revealed that variations in the dry-bench processes were the primary cause of discordances.

Conclusions
This study presents a detailed validation framework and empirical recommendations for large panel validation and elucidates the sources of discordant alteration calls by comparing with “gold standard measures.”

Published: July 2023

Abstract

Objectives
Mucosal appendicitis is defined by neutrophilic infiltration limited to the mucosa, with no transmural invasion; it is currently a controversial entity. The aim of our study was to determine whether mucosal appendicitis represents an early stage of acute appendicitis (AA) or should be considered a negative appendectomy.

Methods
A retrospective study was performed of children with suspected AA who underwent surgical treatment between 2017 and 2020. The participants were divided into 2 groups according to histologic appendiceal findings: mucosal appendicitis (MA) and negative appendicitis (NA). Demographic, clinical, ultrasound, and laboratory features were compared between the groups.

Results
A total of 1269 patients with suspected appendicitis in whom appendectomy was performed were included, with a median age of 10.5 years. Mucosal appendiceal inflammation was histologically confirmed in 30 cases (MA group), while no inflammation or other pathologic findings were observed in 25 cases (NA group), with no differences in demographic, clinical, or ultrasound features between the groups. Those in the MA group presented with significantly higher leukocyte and neutrophil counts and higher neutrophil to lymphocyte ratios (NLRs) than those in the NA group (P &lt; .001). The NLR was the parameter with the highest area under the curve (0.736) for the diagnosis of MA. A cutoff of 3.20 was established, with a maximum sensitivity and specificity of 62.5% and 78.9%, respectively.

Conclusions
Mucosal appendicitis presents with laboratory and histologic inflammatory features that can be distinguished from nonappendicitis and should therefore be considered a pathologic entity within the spectrum of AA. Preoperative leukocyte and neutrophil counts and NLRs may help reduce the number of negative appendectomies.
Trends in Cannabis Use, Blood Pressure, and Hypertension in Middle-Aged Adults: Findings From NHANES, 2009–2018
Authors: Corroon Jamie , Grant Igor , Bradley Ryan , Allison Matthew A 
Published: July 2023

Abstract

BACKGROUND
Observational studies investigating associations between cannabis use and blood pressure (BP)/hypertension are inconsistent.

METHODS
Cross-sectional data from the National Health and Nutrition Examination Survey (NHANES) were analyzed for five 2-year cycles between 2009 and 2018 representing 9,783 middle-aged adults (35–59 years). Hypertension was defined as systolic BP (SBP) ≥130, diastolic BP (DBP) ≥80, or a BP medication. Sample-weighted multivariable logistic regression models were used to assess associations between cannabis use and BP and hypertension.

RESULTS
One quarter of respondents (n = 2,228) reported a history of monthly cannabis use for more than 1 year, which was consistent over the study period (P for trend = 0.75). Approximately 48% (n = 4,831) met the definition of hypertension. While a significant positive trend was seen over time for mean SBP and DBP (P = &lt;0.01 for both), no significant trend was seen in prevalent hypertension (P for trend = 0.23). In adjusted models, compared with never use, a history of monthly cannabis use for more than 1 year was not associated with increased BP (mean SBP: 124.5 mm Hg (95% confidence interval [CI], 122.4–126.6) vs. 122.6 (95% CI, 120.9–124.2); DBP: 74.7 mm Hg (95% CI, 73.1–76.2) vs. 74.1 (95% CI, 72.8–75.4)), or prevalent hypertension (odds ratio = 0.88 (95% CI, 0.62–1.24)). Results from analyses of duration of monthly use, and recency and frequency of recent use were similar.

CONCLUSIONS
A history of monthly cannabis use for more than 1 year was not independently associated with either increased BP or prevalent hypertension in a nationally representative sample of middle-aged US adults.
