Abstract
Due to the constantly growing demand for flour confectionery and culinary products, it became necessary to develop specialized requirements for the quality of wheat flour as a raw material. To date, there are no such requirements in our country, and for the production of these products, bakery flour obtained according to the traditional wheat grind scheme was used, the quality of which had to be leveled depending on the range of confectionery products. One way to solve this problem is to differentiate the properties of wheat flour according to its intended purpose and their rationing. The purpose of the study is to develop quality requirements for Russian wheat flour for the production of wafer sheets according to objectively and reliably determined indicators of the dough rheological properties using an alveograph device to create, in the future, a system for classifying wheat flour by its intended purpose. Flour quality assessment was carried out using domestic devices and laboratory equipment (MOK system, Falling-number value, etc.); the dough rheological properties were evaluated by an alveograph device (company Chopin, France), wafer sheets were baked and evaluated using methods previously developed by the authors. The analysis of the interdependence of standardized quality indicators, as well as newly developed ones, was conducted to identify indicators that differentiate the quality of wheat flour by its intended purpose, i.e. by finished products. For this, methods of mathematical statistics were applied.

Published: November 2021

Abstract
To increase the efficiency of crop production in the arsenal of the agronomic service there is a number of techniques, methods and technologies that reveal the potential of agricultural plants for all stages of production, starting with soil preparation, selection and preparation of seeds for sowing, agrotechnological measures during the growing season, harvesting technologies, storage and processing of products. The article presents the results of experimental studies on the use of the energy of ultra-high frequency electromagnetic fields for pre-sowing treatment of lupine seeds in order to increase their germination. Revealed the relationship between the parameters of microwave exposure and seed germination. The areas of modes where microwave treatment allows to increase germination, as well as areas of modes in which the impact does not reach the planned effect, or has a negative (depressing) effect, have been determined. Recommendations are given for ensuring the optimal modes of microwave processing and ensuring control of the parameters of the technological process. Based on the results obtained, it can be reliably asserted that the region of microwave treatment of lupine seeds, with a result exceeding the control values, is observed at exposure in the range from 50 to 60 s and at a specific microwave power of exposure from 1.0 to 1.17 kW/kg. The best result of an increase in germination by 1.5% was obtained at 60 s and 1.17 kW/kg. When treating seeds, it is recommended to maintain an average microwave heating rate of 0.50 °C/s until an average microwave heating temperature of 51.5 °C is reached.

Published: November 2021

Abstract
The analysis of the content of pigments in the stems of clonal apple rootstocks bred by Michurinsky State Agrarian University showed a high content of anthocyanins (more than 200 mg/100 g for rootstock 54-118). When determining the qualitative composition, it was revealed that anthocyanins in the stems of the rootstocks are represented by three groups, while there are differences in the shape of the rootstocks. As a source of pigment production, it is necessary to select rootstocks with a high endogenous synthesis of anthocyanins (i.e. red-leaved forms 54-118, 57-491, 98-7-77, etc.), during the cultivation of which, in addition to the main product—detachable rooted cuttings-one can additionally receive from 3 to 10 kg of anthocyanin dyes from 1 hectare of mother plant.

Abstract
The level of land use in agricultural regions has a major impact on the degree of ensuring their food security. The result of thirty years of land reforms is the creation of a system of multi-layered economy in rural areas. The studies were conducted on the basis of data from the Tambov Region, a region with a soil cover mainly represented by leached chernozems. The most effective use of land resources was carried out in 2015-2019 in the households of the population, which have a major role in ensuring food security in the region. In general, in the Tambov region, the level of full self-provision for milk, eggs, fruits, and vegetables has not been reached. The solution of this problem lies in the restoration and improvement of soil fertility in farms of all categories of management. The article outlines its main methods that allow the greatest use of the biological potential of agricultural production.

Published: November 2021

Abstract
The economic instability of recent decades has various social consequences. One of which is the emergence of abandoned agricultural areas. Analytical studies have shown that geolocation, aimed at creating a digital image of agricultural areas, reveals exclusion zones. The government has set the task of developing programs to involve the agricultural turnover of unused land. It is proposed to carry out a system-architectural design of the target zoning of territories. The selection of the basic model within the architecture of the Database of agricultural lands in circulation is supplemented by a block of a digital image for recognizing resource opportunities. The problem of developing a formalized set of typed commands that structure knowledge about the state of territories and their functionality for expert programming systems is solved. The database is formed from declarative (factual), procedural, and control knowledge. To form the database, the state of unused agricultural land in the country was shown. A forecast was given by the Ministry of Agriculture of Russia for the involvement of fallow lands in the turnover by the end of 2030. The concept of the efficiency of involving unused agricultural land into circulation was presented. A mathematical description of the risks and a graphical presentation of ways to achieve the efficiency of returning unused land by a set of indicators of risk restrictions were given. The key advantage of the developed concept is the creation of a modular-type production infrastructure, which is modernized and filled according to the current needs of economic activity, which is flexible to changes in internal factors and does not require external resources.

Abstract
Reclamation complexes, the key element of which are bypass canals, are actively used for effective agricultural work. For the development of reclamation canals. as a rule, excavator equipment is used, which subsequently ensures their effective functioning. The analysis of the impact of the efficiency of the functioning of amelioration systems on the agro-industrial complex (AIC) sectors revealed a significant dependence on obtaining high-quality crops or pastures. Factors were identified that reduce the quality of reclamation work. Among them, the indicator of positioning accuracy of the profile of the soil during clearing or arrangement of channels is highlighted as the main one. It was proved that the installation of automated leveling systems will provide technological improvement to the excavator. Modernization of excavators by introducing automatic leveling systems (ALS), allows you to increase the speed and accuracy of work, and therefore productivity. There are three main ALS solutions for excavator operation: ALS 2 D control system; ALS satellite monitoring system; ALS AUTO satellite leveling system. It was determined that for using ALS AUTO, the quality of the work performed does not depend on the human factor. Field tests were carried out at the test site with quality control of the construction embankments with JCB JS 205 excavator modernized with ALS. The data obtained were compared with the results of grading with a JCB JS 205 excavator without ALS. Based on the results of the data analysis, it was found that with the introduction of automatic leveling systems, the productivity of the equipment increases by 200%, and the accuracy of the work performed has increased 2 times.

Published: November 2021

Abstract
The paper presents data on the effect of electric current on the quantitative index of Mucor and Bacillus fungal colonies in bedding litter. It was found that with an increase in direct current to 3A, the quantitative index (%) of Mucor fungal colonies sharply decreases from 45 to 3 (by 42%), and the quantitative index (%) of Bacillus fungal colonies decreases from 70 to 50 (by 20%). Fresh litter has high acidity, and it cannot be used without preliminary processing and electrical decontamination in ground trenches and bioreactors.

Published: November 2021

Abstract
Segmentation of bone regions allows for enhanced diagnostics, disease characterisation and treatment monitoring in CT imaging. In contrast enhanced whole-body scans accurate automatic segmentation is particularly difficult as low dose whole body protocols reduce image quality and make contrast enhanced regions more difficult to separate when relying on differences in pixel intensities. This paper outlines a U-net architecture with novel preprocessing techniques, based on the windowing of training data and the modification of sigmoid activation threshold selection to successfully segment bone-bone marrow regions from low dose contrast enhanced whole-body CT scans. The proposed method achieved mean Dice coefficients of 0.979 ± 0.02, 0.965 ± 0.03, and 0.934 ± 0.06 on two internal datasets and one external test dataset respectively. We have demonstrated that appropriate preprocessing is important for differentiating between bone and contrast dye, and that excellent results can be achieved with limited data.

Published: November 2021

Abstract
Comprehensive water quality assessment plays a vital role in decision making for the sustainable management of urban rivers, and thus the exploration of integrated ecological assessment methods for water quality has become a major requirement. This study assessed the water quality of the North Canal River on the basis of its ecological status using the phytoplankton functional groups (PFGs) approach. The river runs through the megacities of the Beijing-Tianjin-Hebei region in China, and is mainly replenished with reclaimed water. The results showed that the PFGs approach is much better for evaluating the water quality of urban rivers than the conventional physicochemical index method and phytoplankton diversity metrics, because the PFGs approach is more sensitive to the spatiotemporal variations in the water quality of urban rivers. The average Q

r
index, for ecological status estimation in rivers, based on the PFGs of the North Canal River was 3.30, indicating ‘good’ water quality. In the dry season, the dominant PFG upstream was group D (Cyclotella spp.), whereas the major downstream PFGs had changed to group Y (Glenodinium spp., Cryptomonas ovata, and Cryptomonas erosa) and W1 (Euglena spp. and Gonium pectoral). While the dominant PFG throughout the river changed to TB: Melosira spp. in the wet season. The Q

r
at each site was one to two grades lower during the wet season than the dry season, indicating that water quality was worse in the wet than the dry season.
Study of thermoplasmonic properties of gold nanodimer in visible -infrared region of electromagnetic spectrum
Authors: Pathak Nilesh Kumar , Sarathi Partha 
Published: November 2021

Abstract
In the present study, the heat generation in gold nanodimer when irradiated at their localized surface plasmon resonances is investigated numerically. The theoretical calculations are performed employing the first principal approach to obtain the absorption cross-section of gold nanodimer for different parameter ranges. The heating mechanism is enumerated in terms of its temperature by solving the steady-state heat transfer equation which depends on the absorption cross-section and surface plasmon resonance wavelength. These surface plasmon resonances are quite sensitive to the distance between the dimer and have been tuned from visible to IR range by managing the distance between spheres from 0 to 6 nm. The computation of normalized electric field distribution of gold nanodimer under the plasmon resonance has been mapped using boundary element method(BEM) which enables visualization of the local hot spot that plays a significant role in optical heating applications. The work furnishes the basic understanding of the heating mechanism of gold nanodimer which can find application as plasmonic nanoheaters in several branches of science in visible and near-infrared regions of the electromagnetic spectrum.
Cardiac magnetic resonance in the assessment of pericardial abnormalities: a case series
Authors: Mano T Branco , Santos H , Rosa S Aguiar , Thomas B , Baquero L 
Published: November 2021

Abstract

Background
Cardiac magnetic resonance (CMR) has a unique role in evaluating pericardial disease, permitting non-invasive tissue analysis, and haemodynamic assessment.

Case summary
In Case 1 of recurrent pericarditis, CMR confirmed reactivation of inflammation with late gadolinium enhancement and native T1/T2 mapping techniques, prompting therapeutic changes. In constrictive pericarditis, CMR is the only modality capable of differentiating a subacute potentially reversible form (Case 2), from a chronic, burnt out irreversible phase characterized by constrictive physiology (Case 3).

Discussion
Cardiac magnetic resonance is an effective tool to tailor individual therapy, particularly in cases of recurrent and constrictive pericarditis. Late gadolinium enhancement provides diagnostic and prognostic information, and multiparametric mapping has emerged as a promising tool with incremental diagnostic value.
Multiple coronary artery perforation following global pericardial tamponade in a patient with prior coronary artery bypass graft surgery: a case report
Authors: Yamada Takehiro , Aoyama Takuma 
Published: November 2021

Abstract

Background
Patients who undergo coronary artery bypass graft (CABG) surgery rarely develop global pericardial tamponade due to pericardial adhesions. There are no reports of multiple coronary artery perforations following global pericardial tamponade during percutaneous coronary intervention (PCI) in these patients.

Case summary
A 52-year-old male who underwent CABG surgery developed effort angina pectoris. Coronary angiography demonstrated chronic total occlusion (CTO) of the first diagonal branch with severe stenosis of the second diagonal branch. Because his chest pain did not improve with medical therapy and ischaemia of the left ventricular anterolateral wall was confirmed by myocardial scintigraphy, PCI was performed. The second diagonal branch stenosis was passed anterogradely by a 0.014-inch coronary angioplasty guidewire, while the first diagonal branch CTO was recanalized by side-branch intravascular ultrasonography-guided parallel wiring. After stent deployment, coronary artery perforation at the distal end of the second diagonal branch was detected via contrast injection. We immediately performed intravascular haemostasis, leading to the disappearance of contrast. However, multiple bleeding sites were visualized by angiography at different sites of coronary arteries, including the circumflex artery. Although intravascular haemostasis is a standard procedure, we could not control rebleeding. Despite intensive care, the patient died.

Discussion
Increased tissue pressure due to bleeding possibly led to global pericardial tamponade with multiple coronary artery perforations. We report a rare case of a patient with multiple coronary artery perforations during coronary intervention.
Age- and Sex-Dependent Changes of Free Circulating Blood Metabolite and Lipid Abundances, Correlations, and Ratios
Authors: Di Cesare Francesca , Luchinat Claudio , Tenori Leonardo , Saccenti Edoardo 
Published: November 2021

Abstract
In this study, we investigated how the concentrations, pairwise correlations and ratios of 202 free circulating blood metabolites and lipids vary with age in a panel of n = 1 882 participants with an age range from 48 to 94 years. We report a statistically significant sex-dependent association with age of a panel of metabolites and lipids involving, in women, linoleic acid, α-linoleic acid, and carnitine, and, in men, monoacylglycerols and lysophosphatidylcholines. Evaluating the association of correlations among metabolites and/or lipids with age, we found that phosphatidylcholines correlations tend to have a positive trend associated with age in women, and monoacylglycerols and lysophosphatidylcholines correlations tend to have a negative trend associated with age in men. The association of ratio between molecular features with age reveals that decanoyl-l-carnitine/lysophosphatidylcholine ratio in women “decrease” with age, while l-carnitine/phosphatidylcholine and l-acetylcarnitine/phosphatidylcholine ratios in men “increase” with age. These results suggest an age-dependent remodeling of lipid metabolism that induces changes in cell membrane bilayer composition and cell cycle mechanisms. Furthermore, we conclude that lipidome is directly involved in this age-dependent differentiation. Our results demonstrate that, using a comprehensive approach focused on the changes of concentrations and relationships of blood metabolites and lipids, as expressed by their correlations and ratios, it is possible to obtain relevant information about metabolic dynamics associated with age.
TopoFun: a machine learning method to improve the functional similarity of gene co-expression modules

Published: November 2021

AbstractA comprehensive, accurate functional annotation of genes is key to systems-level approaches. As functionally related genes tend to be co-expressed, one possible approach to identify functional modules or supplement existing gene annotations is to analyse gene co-expression. We describe TopoFun, a machine learning method that combines topological and functional information to improve the functional similarity of gene co-expression modules. Using LASSO, we selected topological descriptors that discriminated modules made of functionally related genes and random modules. Using the selected topological descriptors, we performed linear discriminant analysis to construct a topological score that predicted the type of a module, random-like or functional-like. We combined the topological score with a functional similarity score in a fitness function that we used in a genetic algorithm to explore the co-expression network. To illustrate the use of TopoFun, we started from a subset of the Gene Ontology Biological Processes (GO-BPs) and showed that TopoFun efficiently retrieved genes that we omitted, and aggregated a number of novel genes to the initial GO-BP while improving module topology and functional similarity. Using an independent protein-protein interaction database, we confirmed that the novel genes gathered by TopoFun were functionally related to the original gene set.

Abstract

Background
The tuberculosis (TB) epidemic is not homogeneous in the general population but presents high-risk groups. People who inject drugs (PWID) are such a group. However, TB among PWID remains largely undocumented. Our goal was to assess the prevalence of TB and the risk factors associated with TB among PWID in Vietnam.

Methods
We implemented a cross-sectional survey among 2 community-based cohorts of human immunodeficiency virus (HIV)-positive and HIV-negative PWID in Hai Phong. Participants were screened for TB using questions on TB symptoms. Those who reported any symptom were accompanied by peers to the TB clinic for chest x-ray. If the latter was abnormal, a sputum was collected to perform an Xpert MTB/RIF test.

Results
A total of 885 PWID were screened for TB. For both cohorts, most PWID were male (&gt;90.0%), with a median age of 42 years. Beside heroin injection, 52.5% of participants reported smoking methamphetamine, and 63.2% were on methadone. Among HIV-positive PWID (N = 451), 90.4% were on antiretroviral therapy and 81.6% had a viral load &lt;1000 copies/mL. Using a complete-case analysis, the estimated TB prevalence was 2.3% (95% confidence interval [CI], 1.0–4.5) and 2.1% (95% CI, 0.8–4.2) among HIV-positive and HIV-negative people, respectively. Living as a couple, arrest over the past 6 months, homelessness, and smoking methamphetamine were independently associated with TB but not HIV infection.

Conclusions
In the context of very large antiretroviral therapy coverage, this extremely high rate of TB among PWID requires urgent actions.
