Authors: Ryabtseva S A , Tabakova Yu A , Khramtsov A G , Anisimov G S , Kravtsov V A 
Published: September 2020

Abstract
The modelling of biofilm development on MK-40 and MA-41Π ion-exchange membrane coupons was conducted in skim milk, sweet whey and acid whey ultrafiltration permeates. The membranes were suspended in permeates for up to five days at the room temperature. The incubation was followed with cleaning procedure including water rinsing, acidic, enzymatic and alkaline steps. The efficiency of each step was estimated by the optical densities of waste cleaning solutions relative to original values prior to cleaning. Cleaning efficiency was influenced by the growth medium, type of membrane and incubation time. The biofilms formed in acid whey permeate showed the highest resistance to the introduced cleaning procedure. Moreover, no increase in the optical density of cleaning solutions was observed for 24-h-old biofilms formed in acid whey permeate. Generally, biofilms demonstrated better attachment to MA-41Π membranes. The acidic cleaning step appeared to remove the highest amount of biofilm material from the membrane. However, in some cases, the full cleaning procedure was insufficient to remove a biofilm.
Towards the development of wheat extruded snacks with reduced gluten toxicity
Authors: Sharikov A Yu , Serba E M , Sokolova E N , Borsheva Yu A , Rimareva L V 
Published: September 2020

Abstract
The negative effects of gluten on human health are becoming a serious problem for the development of new foods. Gluten-free or very low-gluten labeling is an important factor in FMCG food marketing. An alternative to a gluten-free diet is the use of enzymatic hydrolysis to break down the immunogenic polypeptides of the gliadin and glutenin fractions. Gluten polypeptides that are resistant to gastrointestinal digestion can be hydrolyzed by prolyl endoproteases from Flavobacterium meningosepticum, Sphingomonas capsulate and Myxococcus Xanthus, or enzyme preparations from Aspergillus niger or Aspergillus oryzae. In many studies, the ability of high-temperature short-term extrusion to modify molecular structure of gluten and its fractions and improve enzymatic access to the biopolymers is noted. A method for integrating biocatalysis and extrusion processes to reduce or neutralize the immunogenic effect of gluten epitopes and to obtain extruded ready-to-eat snacks is proposed. The process flow chart includes the use of extrusion as a pretreatment stage for enzymatic hydrolysis of wheat and as a stage of thermal and shaping processing of extruded hydrolyzed wheat into ready-to-eat snacks.

Published: September 2020

Abstract
Assessing, monitoring, and managing the financial risks of small agribusiness enterprises under conditions of economic crisis and sanctions is a complex problem. Despite a state support for agriculture, sustainable development of small and medium-sized entrepreneurship in these periods is complicated by agro-economic risks in addition to growing risks of owner’s equity to mitigate the threats to solvency and financial stability, resulting in bankruptcy of small enterprises (SME). The state support mitigates these risks, but the risks do not decrease. Therefore, an important condition for stable and efficient functioning of small agricultural enterprises that considerably contribute to food security and self-sufficiency in Russia is monitoring risks of their financial security, which necessitates methodological approaches to their assessment at the micro level. Despite practical interest of agricultural producers in assessment tools and financial risk management strategies that have a key impact on their overall performance, there is a lack of scientific publications that represent new methods and algorithms for assessing financial risks in agriculture, suitable for practical use by small enterprises. The presented in the article procedure for integrated assessing the total financial risk of sustainable development of small agribusiness enterprises is based on identification and analysis of the risk components and is distinguished by a multifunctional nature and acceptable requirements.
Development of technology of choux pastry semi-finished product enriched with oyster mushroom powder
Authors: Sapozhnikov A N , Kopylova A V , Krainov S A , Kveglis I V 
Published: September 2020

Abstract
Bakery products are popular food product among Russian population. Despite of their high sensory characteristics, they are high-calorie products. For their enrichment with useful substances, the powder obtained from cultivated oyster mushrooms (Pleurotus ostreatus) can be used as a non-conventional plant raw material. The paper presents the results of development of choux pastry semi-finished product decorated with craquelin dough, which are both enriched with oyster mushroom powder. The technological process of semi-finished products obtaining is developed, where the mushroom powder is introduced into semi-finished product formulations in the amount of 2.5%, 5.0% and 7.5% by weight of high-grade wheat flour. The optimal quantity of the powder introduced into craquelin dough is 2.5% from flour weight. The control and experimental samples were evaluated by sensory and physico-chemical characteristics, and their nutritional value was calculated. The research results showed that with the increase of oyster mushroom powder in choux pastry semi-finished products their sensory characteristics improve. Dry matter content increases by 0.8…4.8%, and ash content increases by 0.24…0.55%/. The calculation of samples’ nutritional value shows the increase of proteins, vitamins, and mineral substances content. Herewith, the contents of fats and carbohydrates decrease, which also decreases energy value of semi-finished products. Therefore, the optimal amount of oyster mushroom powder for introducing into semi-finished product formulation is 7.5% from flour weight. The developed semi-finished products are recommended for further practical implementation and technology improvement.
Soil-sedimentary sequences of lake depressions in the steppe zone of West Siberia (Russia)
Authors: Smolentseva Elena N , Gavrilov Denis A 
Published: September 2020

Abstract
Lakes are widely distributed in the steppe zone of West Siberia (Russia). These lakes experienced climate-related fluctuations of water levels and corresponding rhythmic changes in the lake basin landscapes throughout the Holocene. Location, structure and properties of soil-sedimentary sequences (SSS) were studied near the Lake Bolyshoi Bagan, where four SSS profiles were examined. The profiles were located on the lake beach ridges and were of different age. Two types of sediments were found in the SSS structure, namely lacustrine sand of the shore facia (top and middle layers) and subaerial-deluvial loam with gleyic properties (lower layers). The studied SSS showed abrupt textural shifts between sandy deposits and loamy layers. The top part of the younger SSS also contains aeolian layers. The loamy layer, as compared with the sandy one, had increased contents of carbonates and dissolved salts. The lowest soil in all SSS was identified as Protosalic Relictigleyic Solonetz (Loamic, Columnic, Ochric). The surface and buried soils in all SSS were ascribed to the Reference Soil Group of Arenosols. Heterochronicity of surface soils is recorded in the different soil organic carbon content. The studied SSS reflect the interaction of environmental factors in the steppe zone of West Siberia during the Holocene: water level fluctuation in lakes, alternating aeolian and lacustrine sedimentation, and succession of pedogenesis and sediment accumulation periods.

Abstract
This research paper is about the coating processwith biopolymer (polyvynil alcohol) as a coat of different fertilizer granules (Azafoska16:16:16, potassium nitrate and magnesium nitrate as a core material) in presence of nitric acid. The biodegradable polymer layer provides uniform diffusion of minerals into the soil as the polyvinyl alcohol shell decays in the soil. Besides, Scanning Electron Microscope (SEM) and Energy – Dispersive X-ray spectroscopy (EDX - 3600) were carried out for the bio-modified fertilizers. The agrochemical changes of the soil in terms of macro – and microelements were also researched.

Authors: Plotnikova V E , Karetkin B A , Panfilov V I 
Published: September 2020

Abstract
The lactobacilli (L. plantarum, L. bulgaricus, L. salivarius, and L. rhamnosus) growth in water extracts of Jerusalem artichoke tubers (solvent ratio of 1:10) with solid particles was studied. The cultures were found to have great specific growth rates and high abundance (up to 10.3 log (CFU/ml)) for 6 hours. The adhesion of the cells to the tuber particles was revealed by a modified counting technique and confirmed by scanning electron microscopy. Lactobacilli were shown to be able to maintain the abundance required (not less than 7.5 log (CFU/ml)) at 2–6 °C for 28 days, which was presumably influenced by the adhesion of the cells to the tuber particles. The data obtained allowed claiming that water extracts of Jerusalem artichoke tubers are promising for production of probiotic functional beverages with lactic acid bacteria.

Physiological and biochemical status of newborn piglets
Authors: Tkacheva E S , Medvedev I N 
Published: September 2020

Abstract
The flow rate in newborn piglets of all types of metabolism strongly determines the intensity of their growth and development. At the same time, many of their normative indicators in newborn piglets in the conditions of central Russia remain not fully understood. In piglets kept in Central Russia, during the neonatal period, the level of total protein rapidly increased due to an increase in the albumin and globulin fractions. This was accompanied by an increase in their blood urea, reflecting the intensification of protein metabolism. In piglets, an increase in glucose and triglyceride levels with a decrease in cholesterol concentration was noted in the blood during the first 5 days. During the neonatal period, the observed piglets showed an increase in the activity of alkaline phosphatase and gamma-glutamyl transferase. This was accompanied by a decrease in the activity of transaminases in their blood and the stability of the functional activity of lactate dehydrogenase and creatine kinase. The detected concentrations of the metabolites taken into account and the found activity of the registered enzymes can be considered as normative for newborn piglets kept in central Russia.

Authors: Kryuchkova V V , Gorlov I F , Belik S N , Kamlatsky A S 
Published: September 2020

Abstract
The analysis of literature found prebiotic properties of inulin and white currant’s health-promoting properties and rich chemical compositions that allow these products to be considered functional food ingredients with bifidogenic, immunomodulating, antioxidant, prebiotic, and hepatoprotective properties, which became a reason for inulin and white currant to be used for enrichment of a dairy product. The experimental studies have established the type of starter microflora—lactic acid and bifidobacteria. The optimal method of heat treatment and technological stage and doses of inulin (3.0%) and unclarified white currant juice (3.0%) were determined, i.e., holding juice and inulin dissolved in milk at t=65±2°C for 25-30 minutes, cooling to t=14±2 °C, and adding to fermented milk product cooled to t=14±2 °C. Qualitative indicators of the fermented milk product enriched with inulin and white currant were higher than those of a traditional product. The new product met the requirements of technical regulations and can be recommended as a functional product for systematic consumption by different age groups of population without restrictions.

Authors: Oni Taiwo Oluwasesan , Ayodeji Simon Olusegun 
Published: September 2020

Abstract
In an attempt to produce fuel from plastic waste, a cylindrical fixed-bed pyrolysis reactor with a capacity of 0.01053 m3 was designed and fabricated. The pyrolytic fuel produced serves as a substitute to fossil fuel. A thermal degradation process, known as fixed-bed pyrolysis, was employed to obtain the pyrolytic fuel from the plastic waste. The operating pressure and the design pressure of the pyrolysis reactor are 25.16 MPa and 28.93 MPa, respectively. The performance testing of the reactor shows that the pyrolytic fuel has higher calorific value, flash point, cetane rating, and density of 39.5 MJ kg−1, 72.5 °C, 40.5, and 804.0 kg m−3, respectively. The corresponding values for the fossil fuel (diesel) are 44.8 MJ kg−1, 68.0 °C, 48.0, and 820.0 kg m−3, respectively. It was confirmed through the performance testing that the reactor was properly designed and can, therefore, be reliably used to produce pyrolytic fuel, which can be made use of as a good alternative to fossil fuel.
Comment on Sarah Maza’s “The Kids Aren’t All Right”
Authors: Milanich Nara 
Published: September 2020

Abstract
In a complement to the 2020 AHR Roundtable “Chronological Age: A Useful Category of Historical Analysis” (125, no. 2), this AHR Exchange focuses on the history of children and childhood. Sarah Maza presents a critical review essay, highlighting the limiting factors in the expanding field of childhood studies. Children, she observes, produce few sources of their own voices, have limited agency, and as individuals and as a group soon outgrow their subaltern status—they grow up. Robin P. Chapdelaine, Nara Milanich, Steven Mintz, Ishita Pande, and Bengt Sandin—historians representing diverse geographical, theoretical, and methodological perspectives on the history of children and childhood—react to Maza’s observations by bringing up important methodological questions about subjecthood, agency, and modernity. Maza’s rejoinder reflects on these questions and on the possibility of age-based historical agency.
Shark: fishing relevant reads in an RNA-Seq sample
Authors: Denti Luca , Pirola Yuri , Previtali Marco , Ceccato Tamara , Della Vedova Gianluca , Rizzi Raffaella , Bonizzoni Paola 
Published: September 2020

Abstract

Motivation
Recent advances in high-throughput RNA-Seq technologies allow to produce massive datasets. When a study focuses only on a handful of genes, most reads are not relevant and degrade the performance of the tools used to analyze the data. Removing irrelevant reads from the input dataset leads to improved efficiency without compromising the results of the study.

Results
We introduce a novel computational problem, called gene assignment and we propose an efficient alignment-free approach to solve it. Given an RNA-Seq sample and a panel of genes, a gene assignment consists in extracting from the sample, the reads that most probably were sequenced from those genes. The problem becomes more complicated when the sample exhibits evidence of novel alternative splicing events. We implemented our approach in a tool called Shark and assessed its effectiveness in speeding up differential splicing analysis pipelines. This evaluation shows that Shark is able to significantly improve the performance of RNA-Seq analysis tools without having any impact on the final results.

Availability and implementation
The tool is distributed as a stand-alone module and the software is freely available at https://github.com/AlgoLab/shark.
