Authors: Obluchinskaya Ekaterina Dmitriyevna , Zakharova Lubov Viktorovna
Published: January 2021

The polyphenol content in the brown algae of the Barents, White Seas, as well as the water areas of the Northwest Atlantic (the Norwegian Sea, the Faxflow bay of the Atlantic Ocean) located in Russia, Norway, Greenland, and Iceland are compared. Algae of the following species were used for this study: Fucus vesiculosus, Fucus spiralis, Fucus serratus, Ascophyllum nodosum, Fucus evanescens. It was found that the most productive raw materials for the extraction of polyphenolic compounds are brown algae F. vesiculosus, growing in Zavalishin Bay of the Barents Sea (Russia): the highest polyphenol content (14.4%) in the summer of 2019 was noted here. Polyphenols detected in F. vesiculosus in the summer from the White Sea on about. Great burnt (13.3%) (Russia), as well as in the Norwegian Sea, Cape Sydspissen (11.6%) (Norway). The minimum content of polyphenols was found in F. spiralis (0.7% dry mass) on the coast of Iceland (Faxflow bay), a low content of polyphenols was characteristic of all types of algae from this location (0.7–2.4%). Three-way analysis of variance (MANOVA) on the example of three types of algae (F. vesiculosus, F. spiralis, A. nodosum) showed that all the studied factors (place of collection, type of algae, fertile phase) are significant. The most significant factor affecting the accumulation of polyphenols by brown algae is the location of algae growth. The high content of polyphenols in the types of algae we studied from Russian water areas allows us to recommend their use as food and medicinal raw materials, as well as raw materials for biologically active additives.

The article to study the texture of paper, in the composition of which the cellulose pulp from the inner layer of mulberry branches bark is added, studies the paper’s absorbency and sorption properties. The absorbency of the paper was determined by the volume of water absorbed by the paper surface while wetting one side of the test sample. It was found that the addition of cellulose pulp from the inner layer of mulberry branch bark to the cotton paper pulp contributes to the strengthening of the structure which is confirmed by the values of mechanical strength and surface absorbency during one-side wetting with water. To study the physical structure of a paper sheet water vapor sorption was investigated in a high-vacuum sorption plant with mercury valves and quartz balances. On the basis of S-shaped sorption isotherms it is determined that the paper sample where the composition contains only cellulose pulp from the inner layer of the mulberry branches bark has the highest sorption properties which indicates the presence of disordered amorphous areas where the accessibility for water molecules is higher. It has been established that in order to obtain paper the structure of which ensured selective absorption of low-molecular fluid it is enough to add 10–20% of cellulose pulp from the inner layer of mulberry branches bark to the paper pulp; and further addition will result in misalignment of the paint contour during printing due to significant deformation of paper size.

The article is devoted to the study of the natural flavonoid dihydroquercetin (0.0125 g per 1 kg of animal weight in daily diet) effect on the development of experimental hypercholesterolemia in rabbits “Chinchilla”. Dihydroquercetin was obtained by extraction with ethyl acetate from crushed Siberian larch (Larix sibirica Ledeb., 1833) wood chips with several cycles of subsequent recrystallization from water (purity 90–92%). Hypercholesterolemia was induced by an atherogenic diet: 0.35 g of cholesterol in the diet per 1 kg of animal weight. The duration of the experiment was two months. It was shown that the introduction of dihydroquercetin into the daily diet of rabbits with alimentary hypercholesterolemia does not significantly affect the level of total cholesterol, as well as the concentration of its atherogenic fractions of LDL and VLDL in the blood. Nevertheless, it was found that, in comparison with the model of hypercholesterolemia, this natural compound contributes to the maintenance of an increased concentration of HDL cholesterol, which has an antiatherogenic effect. Accordingly, this reduces the value of the blood atherogenic coefficient, which reflects the degree of risk of atherosclerosis. In general, the data obtained predetermines the need for further research using various approaches to modeling hypercholesterolemia and atherosclerosis in experimental animals.

Starch is an integral part of grain of cereal crops (including barley), its content and properties significantly affect the processing and quality of products. One of the methods for increasing the variation in starch and amylose contents in starch is chemical mutagenesis. Chemical mutagens provide the possibility to obtain new allelic variations whose genes are involved in starch biosynthesis. In order to create mutant populations of barley, we used in our study the chemical mutagen phosphemide with solution concentrations of 0.002% and 0.01%. Three mutant generations (M1, M2, M3) were grown from the seeds of two barley samples (Zernogradsky 813, k-30453, Russia, var. Erectum; Dz02-129, k-22934, Ethiopia var. Nigripallidum) from the world collection of the N.I. Vavilov All-Russian Institute of Genetic Resources, after treatment with a mutagen in the field, and evaluated by a complex of selection traits. The starch content A and B and amylose content in starch were determined in the grain of the mutant and control populations of the second (M2) and third (M3) generations.

The application of mutagen led to a significant decrease in the mass fraction of amylose in the starch of the studied samples in the second (M2) mutant generation. In the third (M3) generation, the inhibitory effect was preserved only in the sample Dz02-129. In the grain of the Zernogradsky 813 cultivar in M3, the starch and amylose contents in starch were above the control. The selection of forms with the elevated content of amylose, which have potential value for the processing industry, is advisable to carry out, starting with M3.

Published: January 2021

This article presents the classification of the resulting types of powdered cellulosic materials, their scope, as well as the problems arising during production. The main properties of powder cellulose materials are considered. Analyzed the quality indicators of the pulp, previously ground in a disc mill. The main technological parameters of the experimental setup and the comparative characteristics of the used knife grinding sets are presented. In the course of the experimental research, knife grinding sets with straight and curved knives were used. The data obtained confirmed the previously put forward hypothesis about the predominant fibrillation of cellulose fiber milled using a grinding set with a curved blade shape. This feature of the headset design is especially important when grinding hardwood pulp, which has a lower initial value, compared to softwood pulp. The data obtained in determining the degree of grinding, water retention capacity, fiber length of softwood and hardwood cellulose after knife grinding and the degree of polymerization after hydrolysis are presented. A method for producing powdered cellulose material with characteristics similar to microcrystalline cellulose is considered. The regulated parameters of the hydrolysis process are set and a comparison is made of the degree of polymerization of the considered samples of powdered cellulose.

Purpose: Increasing attention has been paid to low-intensity transcranial focused ultrasound (tFUS) for its potential therapeutic effects in Alzheimer's disease (AD). While preclinical studies have shown promising therapeutic effects of low-intensity tFUS in AD models, its efficacy and safety remain unclear in humans. In this pilot study, we investigated the effects of low-intensity tFUS on blood-brain barrier opening, the regional cerebral metabolic rate of glucose (rCMRglu), and cognition in patients with AD.Methods: After receiving institutional review board approval, four patients with AD received tFUS to the hippocampus immediately after an intravenous injection of a microbubble ultrasound contrast agent. Sonication was delivered at low-intensity, at a pressure level below the threshold for blood-brain barrier opening. Patients underwent brain magnetic resonance imaging, 18F-fluoro-2-deoxyglucose positron emission tomography, and neuropsychological assessments before and after the tFUS procedure. A whole-brain voxel-wise paired t test was conducted to compare rCMRglu before and after tFUS.Results: The sonication, as anticipated, did not show evidence of active blood-brain barrier opening on T1 dynamic contrast-enhanced magnetic resonance imaging. rCMRglu in the superior frontal gyrus (P<0.001), middle cingulate gyrus (P<0.001), and fusiform gyrus increased after tFUS (P=0.001). Patients demonstrated mild improvement in measures of memory, executive, and global cognitive function following tFUS. No adverse events were reported.Conclusion: These results suggest that hippocampal sonication with low-intensity tFUS may have beneficial effects on cerebral glucose metabolism and cognitive function in patients with AD. Further larger studies are needed to confirm the therapeutic efficacy of tFUS in AD.

Published: January 2021

A microbial desalination cell (MDC) built on a modified surface has been studied for seawater desalination. The goal of this study is to provide and develop a seawater desalination system that does not require energy support by applying a modification of the anode as an electron acceptor. The different potential charges that occur between anode and cathode can serve as the driving force for electrodialysis of seawater, resulting in its desalination. Yeast has been applied as a biocatalyst and neutral red has been chosen as a redox mediator to facilitate the electron transport originating from the bioactivity of cells. Several types of surface modification have been conducted, i.e., biocatalyst-mediator immobilisation and electropolymerisation of neutral red at the anode surface. The optimisation of each device has been characterised by cyclic voltammetry and chronoamperometry. It has also been observed in a microbial fuel cell (MFC), prior to being functioned in the MDC. The concentrations of salt ion migration have been determined by ion exchange chromatography. This study found that the best configuration of a modified surface was obtained from carbon felt coated by polyneutral red film (CF/PNR); this generated the maximum value of all tested parameters: 42.2% of current efficiency; 27.11% of bio-devices efficiency; 92.5 mA m-2 of current density; and 61% of NaCl transport. Moreover, the modified surface could be a promising method for improving anode performance.

Published: January 2021

Aus, aman and boro are three rice cultivating seasons in Bangladesh. Among these aus is the least cultivated and grown in comparatively small scale due to prevailing drought and less availability of surface water for irrigation. Modern varieties of aus rice cover a significant area of the country conversely local cultivars cover a small area. Aus rice requires much fewer inputs than aman and boro. Due to continuous declination of groundwater level, nowadays more emphasis is given on the extension of aus cultivation throughout the country. The present field study tested yield and morphological attributes of six developed aus rice varieties viz. Binadhan-14, Binadhan-19, BRRI dhan43, BRRI dhan48, BRRI dhan55 and BRRI dhan65 to characterize yield, maturity and phenological properties. The field trial was set at Satvaiyapara of Khagrachari during 2018 following Randomized Complete Block design with dispersed plots. All data were collected at harvest and analysed statistically by Statistix 10. Findings revealed that statistically highest grain yield was produced from BRRI dhan55 (4.49 t/ha) and BRRI dhan48 (4.48 t/ha); the lowest by BRRI dhan65 (3.06 t/ ha). The yield of Binadhan-19 (4.37 t/ha) and Binadhan-14 (3.87 t/ha) was intermediate. In case of maturity, Binadhan-19 (99.33 days) had the shortest life duration and BRRI dhan48 (113.67 days), the longest. The greater portion of the farmers was keen to grow Binadhan-19 and Binadhan-14 instead of BRRI dhan43 and BRRI dhan48 mainly for its short duration, optimal yield, long and slender quality grain. Binadhan-19 might be a promising aus variety in the Khagrachari hill tracts for gaining favourable yield within a short time. Therefore, further studies are needed in jhum cultivation with local cultivars for more significant comparison and acceptability to the rice farming community.

Brinjal and tomato, both of these Solanaceous crops, suffer from different diseases based on their surrounding environment. In charland ecosystem, due to the current trend of climate change these two crops have become vulnerable to disease infection. A comprehensive survey was conducted in Jamalpur and Sherpur districts to measure the severity of major diseases of brinjal and tomato in this region during the rabi season of 2018-19. This survey was based on farmers’ fields targeting 10 different locations where brinjal and tomato were grown extensively. Data were collected from randomly selected farmer’s vegetable fields where incidence and severity were recorded. Through the survey, five (5) diseases based on their incidence and severity were categorized as major diseases in studied areas. Bacterial wilt of brinjal (60%) and viral disease of tomato (41.67%) were found to be higher in incidence. This was a major limiting factor for decreasing total brinjal and tomato production in the charland of Jamalpur and Sherpur. Wilting of tomato (20%), viral disease of brinjal (20%) and phomopsis blight of brinjal (13.33%) were medium in incidence at different locations. Farmers of these areas found these diseases to be a serious threat to future cultivation and expansion of brinjal and tomato in charland.

Authors: Ponnakanti Hari Priya , Gonen Bilal
Published: January 2021

This paper looks at the opportunities and challenges of implementing blockchain technology across medical, finance and banking sectors, and provides a clear view which can enable Blockchain for more extents. After going through few articles and papers related to applications of Blockchain, we gained a vivid knowledge on pros and cons on Blockchain applications from each article. Few drawbacks that we encountered are using Power of Work (POW) in medical sector which is destroying the computing ability at a stage when system is getting bigger and eventually which is wasting lots of resources. One study over conceptual proposal on blockchain is the idea of using trade credit as the value of transactions, and this trade credit is in the scope of trade secret which improves trade confidentiality and makes it more secure. Moreover, centralization systems have few risks owing to their dependence on a high scale which could tamper the data or can even block access, change the rules and might even completely shut down the system. Few more drawbacks are designing and building a secure blockchain system is much more difficult on large-scale of banking sector with large database. To address these challenges, recent developments in blockchain technology are enabling novel opportunities in every possible sector by using Trust-worthy cloud, IoT and artificial intelligence, which makes it more powerful and secure. After analyzing Blockchain implementations and identifying their limitations, we conclude with several promising directions for future research.

Published: January 2021

The poor academic achievement of students in technical colleges in Nigeria has been a major concern to researchers. It is believed that the application of effective instructional methods in technical colleges could enhance overall students’ academic achievement. This demands that teachers in technical colleges should adopt instructional methods that could enhance overall achievement particularly in students’ psychomotor, problem solving achievement and enhance retention in mechanical engineering craft practice in technical colleges. The study investigated the effectiveness of constructivism instructional method on students’ psychomotor achievement, problem-solving and retention in mechanical engineering craft practice in technical colleges in Delta State. Three research questions guided the study and three null hypotheses were tested at 0.05 level of significance. The study adopted the quasi-experimental research design. Population of the study was 97 vocational II mechanical engineering craft practice (MECP) students in the six technical colleges in Delta State. A sample of 82 was used for the study. Instruments for data collection were Mechanical Engineering Craft Practice Achievement Test (MECPAT) and the lesson plans for the experimental and control groups. The instruments- MECPAT and   lesson plans; were face and content validated by three experts, two from the Department of Technology and Vocational Education and one from Measurement and Evaluation Unit of the Department of Educational Foundation; all in Nnamdi Azikiwe University Awka. Test–retest method was used to establish reliability of MECPAT and was calculated using Pearson Product Moment Correlation which yielded a correlation coefficient value of 0.87. Arithmetic mean was used to analyze data relating to research questions and while analysis of covariance (ANCOVA) was used to test the null hypotheses. Findings revealed that students taught  mechanical engineering craft practice using constructivism instructional method performed better, possessed requisite problem solving skills and had better knowledge retention than those taught with lecture teaching method (LTD). Based on the findings, it was concluded that constructivism instructional teaching method (CITM) is an effective and efficient mode of instruction with capacity of improving students’ learning outcome, problem solving techniques and retention ability level. Consequently, it was recommended among others that technical teachers should use constructivism instructional method in teaching mechanical engineering craft practice so as to enhance students’ psychomotor achievement in subsequent public examination.

Published: January 2021

The distribution of soil organic matter (SOM), nitrogen (N), potassium (K), total calcium carbonate (CaCO3) and pH was studied in relation to three soil tillage practices: conventional (CT) using  mouldboad plough followed by three crossing of off-set disc harrow, tooth harrow and seed drill, Reduced (RT) using a chisel, and no-till (NT) using direct driller and 2 plant species: Vicia faba and Durum wheat,  grown in a clayey soil of the semi-arid region of Kef (North western Tunisia) during three years  2009-2011.

Results showed that, under NT, Vicia faba increased SOM and N in the first fifteen centimeters by 20% and 84% respectively as compared to the CT, and reduced soil pH by 0.1 unit. Indeed, Vicia faba benefited from the residues of the Durum wheat. In contrast, CT buried the residues of the previous crop increasing the rate of SOM and N in the subsoil (30-45 cm depth). This made clear that NT, had the benefit of improving top-soil fertility and putting soil nutrients at the reach of the Vicia faba plant roots. Moreover, NT increased the concentration of K in the top-soil which helped seedlings and young plants resisting biotic and non biotic stresses imposed by the semi-arid environment.

Authors: Osaat Dinah Sunday
Published: January 2021

The study was designed to investigate level of teachers’ awareness of their roles in counselling secondary schools for skill acquisition in rivers state. The study adopted a descriptive survey design. The population of the study consist of 8196 (4436 males and 3760) females. A samples size of 450 teachers which was 5% of the population was selected being 222 males and 190 females, using the stratified random sampling technique. The instrument for data collection included a self constructed questionnaire’, which was based on a four point likert type scale of very high extent (4points), high extent (3 points) low extent (2 points) and very low extent. (1point).The mean and standard deviation were used to answer the research questions. Findings showed among others that the extent of teachers’ awareness of their roles in counselling secondary school students for skill acquisition in school is poor and this implies that the students are not exposed to adequate knowledge of the need for skill acquisition which will still lead to laziness and idleness of our graduates. The study therefore recommended among others that ; adequate training should be given to teachers of their roles as counsellors in secondary schools and enough time should be created for guidance and counselling programme in the school time table so that teachers can comfortably handle their clients
Rank and Representation: A Quantitative Analysis of Female Representation Within Entry Level Faculty Positions
Authors: Nicholson Nicole
Published: January 2021

The representation of women in leadership positions and as tenured faculty in higher education has been an issue of concern for a number of years across academic disciplines. What remains unclear is whether this trend is also observed all the way down to entry-level positions in the field of education alone.  The purpose of this quantitative, correlational study was to determine if women and men occupying the non-tenured track ranks of assistant and associate professor were equally represented in the field of education at post-secondary, credential granting institutions in California (n=46). Between groups comparisons indicated that female, assistant professors significantly outnumbered men at both public and private California universities (p<0.0001), and outnumbered men as associate professors at private universities (p=0.0148).  Within groups comparisons indicated that while fewer in number, a greater percentage of men occupied the rank of associate professor, thus outranking their female colleagues at public and private learning institutions (54.5% and 44.8%, respectively). However, the difference was not statistically significant.
A Study on Intercultural Contact Factors and Acculturation: a Survey of African Merchants in Guangzhou
Authors: WU Yiming , GAO Wenjing
Published: January 2021

This paper adopted a qualitative study of questionnaires to identity how selected intercultural contact factors are correlated with psychological and sociocultural adaptation.

It is found that psychological and sociocultural adaptation situations of African merchants in Guangzhou are both moderately well;psychological adaptation of African merchants was proved to be correlated with 5 intercultural contact factors.; the sociocultural adaptation of African merchants was proved to be correlated with 5 intercultural contact factors;correlation analysis proved that outgroup social support has a stronger positive correlation with both psychological and sociocultural adaptation than ingroup social support, which is the main source of social support for African merchants;the overlapping and strength differences of correlations show that the two acculturation dimensions of African merchants are distinct and interrelated, thus verified the Colleen Ward's two-dimension acculturation model in the group of African merchants in Guangzhou.

A Contrastive Analysis of English Novel The Notebook and Its Chinese Translation from the Perspective of Rewriting Theory
Authors: Huang Siyun
Published: January 2021

The Notebook, American novelist Nicholas Sparks’ first romance novel, was published in 1996 and adapted into a movie in 2004 for $115 million box office worldwide. This study selects the original works and Chinese translation for contrastive research. Based on Andre Lefevere’s rewriting theory, this study makes an in-depth analysis of the difference of Ideology and Poetics between the two versions, and explores the reasons for favor from Chinese readers under the influence of ideology and poetics. This study comes to the following conclusions: in terms of ideology, the influence of social ideology on the translator and translator’s understanding of characters have led to language differences between two versions. From the perspective of Poetics, the terms of the original English text are relatively simple and easy to understand, while Chinese translators use a large number of allusions, folk adages and rhetorical devices to arouse interest. A contrastive analysis of two versions from the perspective of rewriting theory provides a completely new perspective for translation studies of novels. Translation studies are no longer confined to the linguistic level, but to the macro level such as culture and society.

Authors: Zheng Junnan , Tao Tingting , Ni Yiming , Ma Liang , Zhao Haige
Published: January 2021

Background: Small cavity left ventricle (SCLV) may affect the clinical outcomes of patients undergoing mitral valve replacement (MVR). This study aims to investigate the incidence of SCLV in patients with rheumatic mitral valve stenosis undergoing MVR and analyze its effect on short-term patient outcomes.
Methods: We retrospectively examined all consecutive patients with isolated or concomitant MVR for rheumatic mitral valve stenosis in our center from 2013 to 2018. SCLV was defined as end-diastolic volume index ≤ 50 ml/m2. After inclusion and exclusion, a total of 1,437 patients were analyzed. The baseline information was collected and compared between SCLV and non-SCLV patients. Multivariate logistic regression analysis was conducted to determine the effect of SCLV on early mortality.
Results: A total of 1,437 patients were included in the study. SCLV was detected in 13.57% of the patients. Compared with the non-SCLV group, patients with SCLV were smaller-sized and primarily female. There were no significant differences between SCLV and non-SCLV patients regarding major postoperative complications, nor were there incidence of prosthesis-patient mismatch. Logistic regression analysis showed that SCLV was not a risk factor for short-term mortality (P = 0.998).
Conclusions: Our results demonstrated that SCLV was not associated with poorer early outcomes after MVR surgery in patients with rheumatic mitral valve stenosis.

The model of the problem of conditional optimization on the set of partial permutations is formulated. The linear form of the objective function is obtained by interpreting the elements of the set of partial permutations as points of the Euclidean space. A combinatorial polytope of allocations is considered for which there is a graph of the set of partial permutations An algorithm for solving this problem is proposed and its practical applicability is demonstrated. The proposed algorithm for solving the conditional optimization problem provides for the representation of the admissible of the Set of Partial Permutations in the form of a graph, which significantly reduces the search path for the optimal solution, as evidenced by the practical example considered.

Authors: Saputra Wely , Yasir Muhammad
Published: January 2021

The goal of this study is to develop the legal status of brand rights as collateral for bank credit guarantees and to analyze the risks of applying brand rights as collateral for bank credit guarantees in Indonesia. Brand rights are part of intellectual property rights which, of course, are of commercial significance to be used as collateral for bank loans. This study is a normative legal research using a regulatory methodology or a legislative approach to interpreting the idea of brand rights being used as security for bank loan guarantees, as laid down in statutory regulations, which are meant to try to get closer to the problems examined on the basis of laws, norms and rules. In compliance with the purpose of the analysis. The findings of the research suggest that Brand Rights can potentially be used as collateral for bank credit guarantees in compliance with the relevant legal requirements, but there are no specific laws and regulations that explicitly govern brands used as collateral for bank credit and, as a result, many banks in Indonesia have not been able to consider brands as collateral for bank credit guarantees.
