Mutations in the β-globin gene cluster can lead to β-thalassaemia, δβ-thalassaemia, hereditary persistence of foetal haemoglobin (HPFH) and some of the haemoglobin variants. The clinical and haematological spectrum of thalassaemia range from benign to pathogenic conditions including severe transfusion dependent thalassaemia. Therefore, it is important to accurately diagnose β-globin gene cluster mutations to prevent thalassaemia major or intermedia offspring. The objective of this study is to detect β-globin gene cluster mutations and large deletions among anaemic patients with elevated HbF level in a tertiary teaching hospital in Kelantan, Malaysia. This study involved 144 anaemic patients with HbF level >1.0%. High-Performance Liquid Chromatography (HPLC) was used to determine the HbF and HbA2 levels. Multiplex-ARMS (ARMS)-PCR and gap-PCR were performed for those patients with high HbA2 level (>3.2%) and normal HbA2 level (≤3.2%) to detect β-globin gene cluster mutations and large deletions respectively. The majority of patients were Malays (99.3%) with mean age of 19.99 ± 1.64 years and female 61.1% predominance. Out of 87 samples tested using multiplex ARMS-PCR against eight targeted single mutation; Cd 41/42, IVS 1–5, Cd 26, Cd 17, Cd 71/72, IVS 1–1, Cd 8/9 and -28 mutations, 65 (74.7%) patients were detected which comprises of Cd 26 (56.3%), Cd 41/42 (11.5%), compound Cd 26 and Cd 41/42 (3.4%) and IVS 1–1 (3.4%). Meanwhile, for multiplex gap-PCR which detect four types of large deletions; Thai (δβ)o-thalassaemia, HPFH-6, Siriraj J and Hb Lepore, one out of 57 patients (1.8%) was found positive with Thai (δβ)o-thalassaemia. There was a significant difference between the mean of HbF level, MCV level as well as MCH level of patients with and without β-globin gene mutations and large deletions (P<0.05). This study highlighted the presence of various types of β-globin gene cluster mutations detection in establishing a definitive diagnosis among this selected group of patients for the large-scale screening of the thalassaemia gene.

Published: February 2021

In the present paper, our purpose is to generalize the Jakimovski-Leviatan-Păltănea operators in the sense of Chlodowsky. After introducing the new operators we first obtain the moments of these operators in order to establish the convergency properties with the help of Korovkin's theorem. After that, we give the local approximation result and the Voronovskaya type theorem. We also examine the convergence properties of the operators in the weighted space of functions. Lastly we determine the rate of convergence of the operators with the aid of the weighted modulus of continuity

Проблема антибиотикорезистентности становится всё более актуальной во всём мире, в том числе и в Республике Беларусь. В связи с этим наблюдается тенденция замены использования антибиотиков и других синтетических антимикробных препаратов на комплексные соединения на основе продуктов животного и растительного происхождения, в том числе пчеловодства. Авторами проведён анализ литературных источников о биологических свойствах продуктов пчеловодства и препаратов на их основе, используемых для лечения и профилактики болезней желудочно-кишечного тракта телят. Установлено, что для профилактики болезней и терапии животных с различными патологиями в ветеринарной медицине наиболее часто применяются: прополис, мёд, цветочная пыльца и перга. Данные продукты пчеловодства имеют сложный химический состав и обладают высокой биологической активностью. Показана высокая терапевтическая и профилактическая эффективность использования на телятах продуктов пчеловодства и препаратов на их основе.

The high therapeutic and prophylactic efficiency of using beekeeping products and preparations based on them on calves is shown.
The Use of Enzyme Immunoassay to Determine Mycotoxin Concentration in Organs, Tissues and Biological Fluids: Review
Authors: Панковец Е.М. , Лях А.Л.
Published: February 2021

Представлен обзор опубликованных исследований, касающихся определения различных микотоксинов в органах, тканях и биологических жидкостях сельскохозяйственных животных и человека. Основной упор сделан на подробном описании пробоподготовки гомогенатов органов к иммуноферментному анализу (ИФА), а также приведены данные по сравнению хроматографических методов исследования с иммуноферментным анализом. Учитывая более доступную стоимость ИФА диагностики, по сравнению с хроматографическими методами, а также легковыполнимую подготовку образцов, ИФА более предпочтителен для так называемого скрининга по определению уровня кумуляции микотоксинов на свиноводческих комплексах, птицефабриках и на других крупных сельскохозяйственных производствах.

A review of published studies regarding the definition of various mycotoxins in organs, tissues and biological fluids of farm animals and humans is presented. The main emphasis is placed on a detailed description of the sample processing of organ homogenates for enzyme immunoassay (EIA) as well as data compared to chromatographic methods of the research with enzyme immunoassay. Considering the more affordable cost of EIA diagnostics in comparison with chromatographic methods as well as the quite easy preparation of samples, EIA is more preferred for so-called screening to determine the level of mycotoxin cumulation in pig breeding complexes, poultry farms and other large agricultural industries.

При выборе метода оценки условий эксплуатации автотракторных дизельных двигателей необходимо учитывать, среди прочих факторов, наиболее часто используемые фазы движения конкретного автомобиля, от которых зависит режим работы двигателя. В статье предложены критерии качественной оценки условий эксплуатации для различных транспортных средств. Для оценки «тяжести» условий эксплуатации тракторов при выполнении различных сельскохозяйственных работ (пахота, боронование, посев и др.) целесообразно учитывать средний эксплуатационный расход топлива. В этом случае указанный параметр определяется отношением общего расхода топлива в литрах к общему времени выполнения трактором конкретной работы в часах. Для автобусов, работающих на маршрутах «Ярославль – центры муниципальных образований», как и для аналогичных перевозок в других регионах нашей страны, рассматриваемый параметр малоинформативен. Здесь для оценки их условий эксплуатации имеет смысл использовать коэффициент КS – количество остановок, приходящееся на один километр маршрута. Для автопредприятий, осуществляющих перевозки пассажиров по указанным маршрутам, рекомендуется проводить плановую ротацию автобусов по маршрутам согласно составленному графику, что позволит усреднить показатели надёжности узлов и агрегатов автобусов (неисправности и отказы) до их капитального ремонта.

When choosing a method for assessing the operating conditions of diesel motor engines, it is necessary to take into account, among other factors, the most commonly used phases of movement of a particular vehicle on which engine operating condition depends. The article proposes criteria for the qualitative assessment of operating conditions for various vehicles. It is advisable to take into account the average operational fuel consumption in order to assess the "heaviness" of tractor operation conditions when doing various agricultural works (plowing, harrowing, sowing, etc.). In this case, specified parameter is determined by the ratio of the total fuel consumption in liters to the total tractor time of the particular operation in hours. For buses operating on the routes "Yaroslavl – centers of municipalities", as for similar transportation in other regions of our country, the parameter under consideration is not informative. Here, to evaluate their operating conditions, it makes sense to use the KS coefficient – the number of stops per kilometer of the route. For automobile companies carrying out passenger transportation along the indicated routes, it is recommended to carry out a planned rotation of buses along the routes according to the made up schedule, which will allow averaging the individual reliability of bus assemblies (faults and failures) before their general overhaul.

Published: February 2021

Gingival composites are one of the gingival recession treatments, which can provide an aesthetic and non-invasive alternative. The compressive strength of gingival composite needs to be known as a benchmark of the restorative material. This study aims to develop and investigate the properties of gingival composite restorative materials using micro, nano, or hybrid silica. The experimental method was employed with one-way analysis of variance, using three different kinds of composite materials: micro, nano, and hybrid silica. Comparison of a matrix to filler ratio for three groups were 30:70, 50:50, 60:40 weight percent, respectively. The compressive strength evaluation was done using a universal testing machine with a 5.6 N load, continuously applied with a crosshead speed of 1.0 ± 0.25 mm/minute until a break or crack formed in the samples. The average results of the compressive strength test micro silica were 71.89 MPa, nano-silica 104.23 MPa, and hybrid silica 106.85 MPa. The p-value between the three groups was 0.001; between micro silica and hybrid silica was 0.001; between micro silica and nano-silica was 0.002, and between nano-silica and hybrid silica was 0.738. This study concluded a statistically significant compressive strength of gingival composite restorative material using micro, nano, or hybrid silica. The gingival composite with hybrid silica had the highest compressive strength among the three fillers.

Multi-cations lead perovskite solar cells have shown higher performance than single-cation perovskite solar cells. This compositional engineering of perovskite material retains the optimum tolerance factor while allowing the tuning of the band gap in addition to the enhanced stability of cubic phase perovskite. However, no in-depth explanation has been provided on the relationship between crystal structure of the perovskite and the solar cell efficiency. In this report, we investigate the effect of lattice disordering of FA

PbI3 perovskite on the tolerance factor and solar cell efficiency. The lattice disordering estimated using Williamson–Hall plot of XRD analysis revealed that the disordering is lowest when x = 0.2 and highest when x = 1.0. Correspondingly, x = 0.2 showed the highest solar cell performance and long carrier lifetime Our results show that the disordering in α phase of FA

Published: February 2021

We investigate light-induced persistent resonance frequency shift on MoS2 mechanical resonators towards optically tunable nano-electro-mechanical systems with optical memory function. After the termination of light irradiation, the resonance frequency shifts downwards and the downshift is maintained for more than 20 min. This behavior is induced by trapped photogenerated holes at defects or contamination on MoS2 similar to the persistent photoconductivity. The trapped holes screen the electrostatic force acting on MoS2, which results in the reduction of the tension of MoS2. The downshift can be eliminated by applying the excess voltage pulse to MoS2 to induce Joule heating.

An effect of alumina additive amount on the main properties of ramming mix samples based on zirconia stabilized with calcium oxide on a phosphate bond was studied, as well as the processes of phase formation in these samples. It was found that, the alumina additive introduction activates the ZrO2 cubic phase destabilization, but does not cause softening of the samples structure. This is due to the fact that, as a result of the interaction of alumina with CaO released from the solid solution with ZrO2, elongated prismatic crystals of calcium hexaaluminate are formed, which reinforce and strengthen the samples structure. It was shown that, the samples composition containing 10 % alumina additive is optimal in terms of porosity, strength, and thermal shock resistance: ZrO2 + НfO2 — 83.52 wt. %; CaO — 3.86 wt. %; open porosity-— 15.9 %, cold crushing strength —62 N/mm2, thermal shock resistance (1300 ºС — water) — 6 thermal cycles, change in linear dimensions — 1 %. The obtained scientific results were used in the technology development of a new type of product — a mixture of powders for zirconia-alumina ramming mix, the manufacture of which was mastered at JSC "URIR named after A. S. Berezhnoy". The developed ramming mix is recommended for use, in particular, for making lining at the border of combustion and mixing zones of carbon black production reactors.

Published: February 2021

Basing on the RATER model of service quality, we explored the role service empathy and assurance in building road transport customers’ loyalty intention. Being a quantitative study, data from 318 valid responses, analyzed with simple regression analysis in SPSS 21.0, indicate that the two constructs – service empathy and service assurance are positive and significant predictors of customer loyalty. Further, with 82% and 78.8% variance explained for assurance and empathy respectively, results indicate that service assurance drives more customer loyalty than service empathy in the organized road transport industry in Nigeria. To attract and retain customers, operators in the industry must be service quality conscious.
Macroeconomic Impact of Refugee Inflow on West African Countries
Authors: Nkwatoh Louis Sevitenyi , Ibrahim Kekere Sule
Published: February 2021

This study investigated the macroeconomic effect of refugee inflow on West African Countries using a panel vector autoregressive approach over the period 1992 to 2018. Our results provide evidence that a positive refugee shock induces a positive effect on GDP per capita, government consumption and labour force. On the other hand, the effect of a shock to refugee exerts a negative effect on the fiscal balance of host Countries. The overall result from the variance decomposition indicates that refugees prefer to migrate to Countries with better economic activities as reflected by the GDP per capita and labour supply, even though the magnitude of contribution of refugees to economic activities is small and significant only in the short run. Hence, refugees do not constitute an economic burden to West African States, but however induce a negative effect on their fiscal balance via extra budgetary expenditure. This calls for a global response to refugee crisis with respect to its fiscal implication on host Countries. This may go a long way in averting another circle of crisis because refugees often exacerbate the worsening economic and social problems of host Countries, leading to increase in government consumption.

O objetivo deste estudo foi realizar uma pesquisa bibliográfica da produção científica sobre aeronaves remotamente pilotadas (remotely piloted aircrafts – RPAs), popularmente conhecidas como “drones”, relatando aspectos históricos, avanços tecnológicos e as diferentes aplicações no manejo agrícola e ambiental. Inicialmente, a tecnologia de RPAs foi usada em aplicações militares, principalmente na Guerra do Golfo, mas suas primeiras aplicações militares datam da década de 1950, e, na década de 1920, já se projetavam as primeiras RPAs para fins bélicos. Recentemente, tem ocorrido um avanço tecnológico nos sistemas baseados em RPAs, e, a partir do final da década de 1990, suas aplicações não mais ficariam restritas ao uso militar, passando, então, a ser usadas por civis em diversos segmentos de mercado. Os exemplos mais evidentes ocorreram na construção civil, na agricultura e na gestão ambiental. Isso se deve ao fato de as RPA apresentarem imagens aéreas com alta resolução espacial e temporal, complementando, assim, os dados disponibilizados por plataformas de satélite e terrestres. Diversos sensores de altíssima qualidade estão sendo projetados e usados nas RPA. São sensores capazes de medir a temperatura da superfície terrestre, captar a luz infravermelha irradiada pela vegetação e mensurar a altura de elementos presentes na superfície terrestre. O uso de RPA abre um novo caminho para cenários ambientais e agrícolas, especialmente por ser uma ferramenta que possibilita a resposta imediata, a tempo para intervenções rápidas em áreas agrícolas, como também em áreas de reserva legal e de preservação permanente degradadas.

A gestão dos recursos naturais de maneira responsável é, sem dúvida, um dos maiores desafios de gestão ambiental. Por isso, técnicas de sensoriamento remoto têm sido cada vez mais usadas objetivando uma melhor e maior tomada de decisão. Este estudo realizou-se na margem noroeste (B) do município de São Francisco, Norte de Minas Gerais, localizado na Bacia alto-média do Rio São Francisco e onde o Cerrado natural sofreu intensa degradação num intervalo de 41 anos (1975–2016). O estudo objetivou, por meio da metodologia de sobreposição de imagens cartográficas, utilizando-se a ferramenta IDW do software ArcGIS 10.2, gerar um mapa capaz de apresentar a média populacional do baruzeiro (Dipteryx alata) por ponto de coleta. Pode-se concluir, após a exitosa experiência metodológica aqui presente, que os exemplares arbóreos do baruzeiro, se usados de modo sustentável, podem contribuir para o desenvolvimento local, haja vista seu potencial comercial. Seu uso responsável, por meio de mecanismos de gerenciamento ambiental baseados nos mapas aqui gerados, é indicado pensando no desenvolvimento econômico e ambiental do município estudado.
