Biology on track: single-molecule visualisation of protein dynamics on linear DNA substrates
Authors: Kaur Gurleen , Spenkelink Lisanne M.
Published: November 2020

Single-molecule fluorescence imaging techniques have become important tools in biological research to gain mechanistic insights into cellular processes. These tools provide unique access to the dynamic and stochastic behaviour of biomolecules. Single-molecule tools are ideally suited to study protein–DNA interactions in reactions reconstituted from purified proteins. The use of linear DNA substrates allows for the study of protein–DNA interactions with observation of the movement and behaviour of DNA-translocating proteins over long distances. Single-molecule studies using long linear DNA substrates have revealed unanticipated insights on the dynamics of multi-protein systems. In this review, we provide an overview of recent methodological advances, including the construction of linear DNA substrates. We highlight the versatility of these substrates by describing their application in different single-molecule fluorescence techniques, with a focus on in vitro reconstituted systems. We discuss insights from key experiments on DNA curtains, DNA-based molecular motor proteins, and multi-protein systems acting on DNA that relied on the use of long linear substrates and single-molecule visualisation. The quality and customisability of linear DNA substrates now allows the insertion of modifications, such as nucleosomes, to create conditions mimicking physiologically relevant crowding and complexity. Furthermore, the current technologies will allow future studies on the real-time visualisation of the interfaces between DNA maintenance processes such as replication and transcription.
Comparing Vocabulary Knowledge Conceptualizations Among Spanish–English Dual Language Learners in a New Destination State
Authors: Oh Min Hyun , Mancilla-Martinez Jeannette
Published: November 2020

Purpose

Despite the unprecedented growth of Spanish–English dual language learners (DLLs) in new destination states—where DLLs have not been historically served—empirical understanding of their language and literacy skills is scant. Drawing on scientific understandings of bilingual language acquisition, we compare monolingually scored and bilingually scored vocabulary knowledge of Spanish–English DLLs in a new destination state.

Method

Participants included second- and fourth-grade Spanish–English DLLs (
N
= 60) in a large urban school district in a new destination state. Students were considered DLLs if their parents indicated that Spanish was spoken at home to some extent. We utilized monolingually scored (Spanish-only and English-only) and bilingually scored (conceptual and total) conceptualizations of vocabulary knowledge. Descriptive analysis and Bonferroni-adjusted multiple comparisons were used to compare vocabulary knowledge by assessment approach (i.e., monolingual or bilingual), grade (i.e., second and fourth), and English proficiency status (i.e., limited English proficient and English proficient).

Results

Findings revealed that (a) DLLs, across grade levels and English proficiency status, demonstrated higher bilingual vocabulary scores compared to monolingual scores and stronger receptive vocabulary performance than expressive vocabulary performance and (b) DLLs' response patterns varied depending on the bilingual assessment approach used, with DLLs in limited English–proficient and English-proficient groups evidencing similar response patterns.

Conclusions

Bilingual scoring of vocabulary knowledge provides a more holistic understanding of elementary-aged DLLs' language skills. Results represent an important step toward shifting school-based assessment practices to incorporate comprehensive and equitable ways to conceptualize and measure elementary-aged Spanish–English DLLs' vocabulary knowledge.

Optimal setting of PV and battery energy storage in radial distribution systems using multi‐objective criteria with fuzzy logic decision‐making
Authors: Selim Ali , Kamel Salah , Jurado Francisco , Lopes Joao A. Peças , Matos Manuel
Published: November 2020

Minimising the total power losses and enhancing the voltage profile is achieved using a proposed multi‐objective chaotic salp swarm algorithm with fuzzy logic decision‐making. The proposed multi‐objective chaotic salp swarm algorithm is utilised to determine the optimal size and location of photovoltaic in radial distribution system to minimise the total power losses, total voltage deviation, and maximise the voltage stability index. In addition, the proposed multi‐objective chaotic salp swarm algorithm is used to find suitable scheduling for battery energy storage charge/discharge during 24 h considering the intermittent nature of photovoltaic power generation. The proposed algorithm is tested on standard and practical radial distribution systems (IEEE 33‐bus and 94‐bus Portuguese systems). The performance of the proposed algorithm is validated by comparing its results with those obtained by other competitive optimisation techniques. The obtained results prove the ability of the proposed algorithm to achieve an efficient setting for photovoltaics and battery energy storages and determine their optimal allocations in order to minimise the power losses and enhance the voltage profile with satisfying all operating constraints.

Published: November 2020

Effect of adding nanofillers on transformer oil breakdown voltage and its thermal performance finds a great interest from researchers and scientists. The impact of oil circulation considering oil forced cooling method on nanoparticles stability in transformer oil is investigated. The stability is considered from breakdown voltage and thermal performance points of view. Titanium dioxide (TiO2) nanoparticles are chosen due to the safety of TiO2 nanomaterial as well as its good performance. First, the optimal concentration of nanosized TiO2 at which maximum breakdown voltage of nanofilled transformer oil is determined and chosen to study the effect of oil circulation on breakdown voltage as well as thermal performance of nanofilled oil. Two reduced experimental models are designed. The first model consists of a galvanized steel tank containing TiO2‐nanofilled transformer oil, at the pre‐determined optimal concentration. This tank is designed to simulate the natural oil cooled transformer. However, the second model that uses a similar tank is designed to simulate a forced cooled transformer. This model consists of a tank containing TiO2‐nanofilled transformer oil, at the pre‐determined optimal concentration, and an oil pump. Breakdown voltage and thermal performance considering the two adapted models are measured in a time period of 60 days.
SELI: statistical evaluation based leaker identification stochastic scheme for secure data sharing
Authors: Gupta Ishu , Singh Ashutosh Kumar
Published: November 2020

Data leakage has become a critical challenge for any organisation, especially when the third party is involved with legitimate permissions to access its confidential data. This study provides a statistical evaluation‐based leaker identification (SELI) scheme to identify the malicious entity when the data is leaked by any agent at some unauthorised place. A new distribution strategy for object and agent selection which enriches the guilty agent recognition is introduced. The three algorithms named SELI–first come first serve, SELI–round Robin (SELI–RR) and SELI–shortest request first (SELI–SRF) are presented for the agent selection. Furthermore, the spurious data objects are added while distributing the data sets among the agents to uniquely identify the leaker. The SELI scheme estimates the guilty entity based on the allocated data among the agents using bigraph. The proposed solution achieves an improvement of up to 25.37 and 58.18% for average probability and average success rate respectively in case of SELI–SRF and 163.68% in case of SELI–RR for detection rate compared to the prior work. In addition to this, the SELI scheme proved its efficiency by securing up to 99.82% accuracy, 99.92% precision, 99.4% recall and 99.97% specificity.
Portfolio management for a wind‐storage system based on distributionally robust optimisation considering a flexible ramping product
Authors: Huang Chenyang , Ma Hongyan , Yan Zheng , Chen Sijie , Li Mingjie
Published: November 2020

A wind‐storage system (WSS) can use the synergy between wind farms and battery storages to mitigate the uncertainty of wind. With the flexible ramping capability of battery storages, a WSS can diversify its portfolio by selling energy, committing regulation services and offering flexible ramping products in a power market. The portfolio management problem of a WSS is studied here. The uncertainties of market prices and wind power are considered. In order to maximise the expected profit in the worst case, a distributionally robust optimisation model is proposed. The model is then reformulated as a solvable semidefinite optimisation problem. Real market data are used in the simulation, which validates the proposed method.

We report observations of five impulsive solar energetic particle (SEP) events observed inside 1 au during the first perihelion pass of the Solar Orbiter mission, which was launched in February 2020. These small events were all reasonably associated with active regions observed from Earth but which had rotated out of view by the time of the Solar Orbiter observations. Even though most of the events were small, their spectral forms,3He content, and association with type III bursts convincingly identifies them as3He-rich impulsive SEP events with properties similar to those previously observed at 1 au. Three of the events showed fast ion rise times, and two of them had long-lasting anisotropies consistent with the Compton-Getting effect.
Modeling the statistics of the cold neutral medium in absorption-selected high-redshift galaxies
Authors: Krogager Jens-Kristian , Noterdaeme Pasquier
Published: November 2020

We present a statistical model of the selection function of cold neutral gas in high-redshift (z = 2.5) absorption systems. The model is based on the canonical two-phase model of the neutral gas in the interstellar medium and contains only one parameter for which we do not have direct observational priors: namely the central pressure of an L* halo at z = 2.5, P*. Using observations of the fraction of cold gas absorption in strong H I-selected absorbers, we were able to constrain P*. The model simultaneously reproduces the column density distributions of H I and H2, and we derived an expected total incidence of cold gas at z ∼ 2.5 of lCNM = 12 × 10−3. Compared to recent measurements of the incidence of C I-selected absorbers (EWλ 1560 >  0.4 Å), the value of lCNM from our model indicates that only 15% of the total cold gas would lead to strong C I absorption (EW > 0.4 Å). Nevertheless, C I lines are extremely useful probes of the cold gas as they are relatively easy to detect and provide direct constraints on the physical conditions. Lastly, our model self-consistently reproduces the fraction of cold gas absorbers as a function of NH I.

Published: November 2020

The method involves calculation and selection of methods of tractor maintenance, taking into account the working conditions of the operator in the field. It is intended for agricultural enterprises with an average annual number of tractors not exceeding 20 units. Calculation for the choice of maintenance methods is carried out on a personal computer in Microsoft Office Excel or a calculator for the minimum value of the unit cost of tractor maintenance. Research objective is to determine the most rational method of maintenance by the specific cost of tractor maintenance. The method allows determining the unit cost of maintenance, either taking into account the additional costs of tractor maintenance when servicing tractors in the field conditions, or without taking them into account. The article presents the selection procedure for maintenance methods, taking into account the working conditions. The annual economic effect from the application of this method, calculated on the example of agricultural enterprises of the Irkutsk region, is 27.8 thousand rubles per tractor. The method was tested as exemplified by farms in the Tulunsky and Cheremkhovsky districts of the Irkutsk region and can be useful to engineers maintaining farming tractors. The results of the study can be used in agricultural enterprises, both the Irkutsk region and the Siberian region as a whole.

Published: November 2020

The microflora of the oral cavity of domestic ruminants, presented by transitive gram-negative species of bacteria (cocci and sticks) in cows, transient and obligate gram-positive (usually cocci) bacteria in sheep was studied. The lowest contamination of the sheep mouth mucosa was observed in autumn, and the largest in summer. Seasonal features of bactericidal activity of saliva and its main components (lysozyme, properdin and complement system) are shown. Differences of the above indicators in cows and sheep are considered. Low activity is typical for saliva complement system in ruminants in general and sheep in particular. Lysozyme activity and properdin content are maximum in cows and sheep in summer, with elongation towards autumn (exception – lysozyme activity in sheep extends in spring).

Published: November 2020

The research presents the findings of DNA testing of allelic polymorphism by the PCR-RFLP method of the SCD1 gene and the relationship of genotypes with the milk fatty acid composition of Holstein cows of Tatarstan population. The research was conducted among 172 Holstein cows at the Integrated Agricultural Production Centre “Stud farm named after Lenin” in Atninsky district of the Republic of Tatarstan in 2017–2018. All genotypes of the SCD1 gene were identified through the research. The milk yield test showed that the maximum content of the mass fraction of fat was in animals with the TT genotype. The significant difference between the content of the mass fraction of fat in milk in individuals by the locus of the SCD1-Fsp4HI gene was: TT to CC – 0.32 % (p < 0.05) and TT to TC – 0.40 % (p < 0.01). The results of chromatography indicate the balance of the milk fatty acid composition of cows with the TT genotype and, as a consequence, its positive effect on the human body. Cows with a homozygous TT genotype are characterized by the optimum ratio of fatty acids in milk fat. The maximum value of the oxygen desaturation index is also observed in animals with the TT genotype by the SCD1 gene.

Published: November 2020

In modern veterinary medicine, the simultaneous occurrence of chronic heart failure and chronic kidney disease is often found. However, the cause and effect often exchange places, which creates great difficulties in the animals’ treatment. Chlofusan acts on both systems. It improves cardiac and renal functions by means of providing cardioprotective and nephroprotective effects. Models of chronic heart failure and chronic kidney disease in rats provide important information on the pathophysiology of these diseases in other animal species, and the assessment of changes in the biochemical analysis of blood makes it possible to assess the state of the heart and kidneys in the study. In the course of research, the results of rat biochemical analysis were studied on models of chronic heart and kidney failure with the introduction of an exogenous nitric oxide donor. Chlofuzan contributes to a partial balance restoration of biochemical blood parameters in rats, which indicates the restoration of the mutual work of the heart and kidneys.

Published: November 2020

The paper presents the results of studies on the creation of an optimal nutritional regime with an analysis of weediness of crops with increased pre-sowing treatment of seeds of growth processes and the resistance of the plants themselves under stressful conditions to form a spring wheat crop. In the initial period of spring wheat vegetation, when plants are affected by sharp temperature fluctuations, soil and atmospheric droughts, it is important to stimulate their stable development and resistance to stress. When satisfying the needs of crops for nutrients, it is important to prevent weeding of crops. The purpose of our study is to study the complex effect of mineral fertilizers, the use of a herbicide and presowing seed treatment with a growth regulator on spring wheat productivity. The studies were conducted in 2016-2018 on the basis of Kazan State Agrarian University on gray forest soil. An analysis of the development of plants on weed grown variants revealed a decrease in the safety of seedlings for harvesting, decreased yield by 0.15-0.28 t/ha and reduced grain quality. The average yield of spring wheat over the years of research when using the herbicide against the background without fertilizers was 1.53 t/ha, 2.66 t/ha against the background of NPK to obtain 3 t/ha of grain and 3.22 t/ha against the background of NPK to obtain 4 t/ha of grain. Combined seed treatment with the growth regulator Zircon and dressing agents contributed to an increase in yield in all nutritional backgrounds by another 3.2–4.4% and an increase in the grain nature and gluten content in fertilized nutritional backgrounds.

Published: November 2020

This research considers the use of the sorption-probiotic supplement Biopinnular in the amount of 0.5 and 1.0 % of the dry matter in the diets of calves of the dairy period. The results allows us to correct the microbiocenosis in the in the digestive tract by suppressing the development of pathogenic microflora and increased reproduction of Lacto- and Bifido bacteria. The studied supplement also contributes to deeper fermentation of fodder mass during digestion in the rumen, which is manifested in an increase in active acidity (pH), cellulolytic activity of bacteria, VFA content as the main product of carbohydrate fermentation, as well as enhanced ammonia-binding function of microflora, which led to better energy and protein availability of their body. This is confirmed by indicators of the morphological and biochemical status of the blood of calves, manifested in a real increase in their red blood cells, hemoglobin, protein and protein fractions. All this was confirmed by the intensity of their live weight gain, accompanied by large average daily (by 8.83 and 23.70 %, respectively) and relative (by 1.63 and 3.86 %) weight gains and smaller (by 0.44 and 0.64) EFU costs per unit of live weight gain. A more pronounced biological effect is observed when using a feed supplement at a dose of 1.0 % of the dry matter of the diet.

Published: November 2020

Studies were conducted on an experimental field of Samara State Agrarian University in20072019 with the purpose of studying the influence of primary soil tillage of typical heavy loam chernozem and aftereffect of different organic fertilizers on the yield of soybeans. The most optimal conditions for the soil density were determined by plowing, which was 0.90-1.10 g / cm3for the growth and development of soybeans. Primary tillage did not have any significant effect on the productive moisture reserves in the meter layer of soil. Shallow tillage and no-till contributed to a 1.3-time increase in weediness of soybean crops compared to plowing. The greatest crop yield 1.45 t / ha was collected by plowing, which was 0.25 and 0.44 t / ha higher than by shallow tillage and no-till respectively. The aftereffect of organic fertilizers promoted the additional soybean yield of 0.17-0.18 t / ha compared to the non-fertilized plot. New types of organic fertilizers were as good as manure in terms of impact on productivity.
Promising directions of technological development and the use of digital technologies in dairy farming
Authors: Ivanov Y. , Tikhomirov I.
Published: November 2020

Nowadays, special attention is paid to increasing the sustainability and competitiveness of dairy cattle breeding, which is due to the need to accelerate the growth of its own milk production to ensure the country’s food security. Among the priority areas for the industry development, many researchers highlight the modernization of the material and technical base by updating fleet of machinery, technological equipment, introducing innovative methods of managing production processes and using modern technologies. An analysis of the current state and the use of technical and technological potential of the industry showed that the bulk of milk produced in agricultural organizations falls on the already morally and physically outdated enterprises that use high-cost extensive production technologies, characterized by low labor productivity. The share of dairy farms with less than 100 cows was 68.9%, while mega-farms account for only 0.3% of the facilities. Small-scale enterprises play a leading role in the livestock of the milking herd. In such farms, 28.7% of cows are kept on a tethered housing system. As a rule, no adequate feeding of animals is provided. However, in terms of the level of milk productivity and product volume, large-scale dairy complexes are currently in the lead with a herd of more than 800 heads at a time, where milk yield per fodder cow exceeds 5000 kg of milk. Considering that the largest number of dairy herds is concentrated on farms with a population of 100 to 200 cows, we consider the most expedient and promising way to improve the efficiency and competitiveness of these enterprises to modernize them technological re-equipment using domestic digital technologies and mechanization means.

Walking is important for human health, and street connectivity has been considered as an important attribute to enhance walking. Although street connectivity has been investigated widely in this field of study, the effects of street connectivity on walking have not been investigated with gated neighborhoods’ perspective. Therefore, this study’s objectives are comparing connectivity in gated and non-gated neighborhoods and investigating the association of connectivity with total walking in developing countries. Space Syntax (axial map) has been used to calculate connectivity in 16 neighborhoods, of Karachi, Pakistan. Neighborhood Physical Activity Questionnaire (NPAQ) has been used (n= 1,042 adults) to calculate total walking. Independent sample t-test has been used to check the differences in connectivity and total walking between gated and non-gated neighborhoods, while cross-tabulation (gamma test) has been used to analyze the association. The results show that connectivity and total walking are higher in non-gated neighborhoods than gated neighborhoods, and there is a small but significant association between connectivity and total walking. It indicates that total walking may be correlated to connectivity, therefore, it should be taken into account while designing neighborhoods.

Authors: Nakano Makibi
Published: November 2020

In local societies, people utilize indigenous ecological knowledge to engage in their livelihood. The study draws from a comparison of the indigenous calendars based on seasonal winds used by the Sama-Bajau fishermen in Banggai Islands, Central Sulawesi, Indonesia. In previous studies about Sama-Bajau people, their ecological background of fishing activity was overlooked, and their seasonal calendar in coral reef area was only reported. This study conducted a qualitative research through semi-structured interviews and participant observation in four settlements. Based on a comparison between the main and other settlements, the study analyzed their indigenous ecological calendar using scientific data and comparing with other society’s data. The results revealed that the classifications of each calendar are critically different. Therefore, according to interviewees, they cannot determine if they previously resided in a region. The findings also suggested that they recognize seasons with a punctual and an irregular classification. Today, they face a contradiction between the indigenous seasonal and modern calendars. Given this problem, a relationship of antagonism and harmony with seasonal knowledge and modern knowledge is observed. A discussion of their adaptation process regarding the diachronic maritime ecology is provided.
