Adherence to malaria rapid diagnostic test results and a qualitative study on Health Workers perception about the test in Agona East District of Ghana
Authors: Ansah-Koi Selina 
Published: December 2020

Abstract
Background Ghana has adopted the policy of diagnostically testing for malaria before treatment. The Rapid Diagnostic Test (RDT) is used to diagnose malaria especially in lower health facilities like Health Centers (HC) and Community-based Health Planning Services (CHPS) Compounds without microscopy. Studies have shown that clinicians do not always adhere to negative malaria test results of the RDT and prescribe anti-malarials. Methods Quantitative aspect focused on how malaria is diagnosed and adherence to negative rapid diagnostic test results using the consulting room register and patients’ folder of six health facilities within the period of July to September 2015. In-depth interviews using purposive sampling was conducted for 14 health workers at Health Centers and CHPS compounds to find out their perceptions about malaria RDT and reasons for adherence or non-adherence to test results.Results Of the six health facilities in the Agona East District, 3.87% (14/362) were presumptively diagnosed with malaria whiles 96.10% (348/362) were diagnosed with malaria using RDT.For those tested with RDT, 15.25% tested negative and 84.75% tested positive. Of those who tested negative, 20.75% were given anti-malarials and 79.25% did not receive anti-malarials. Health workers perceived the Malaria RDT kit as easy to use and also as making work easier. Testing is done mainly because it is a policy. Conclusion The malaria testing rate in the Agona East District is higher than that at the National level. Health Centers compared to CHPS compounds are likely to treat for malaria in cases of a negative test result. There is also high adherence to negative test results. Health workers perceive the RDT as a useful tool which has made malaria diagnosis easy.

Background. Presently, a prospective direction for the development of regenerative medicine in the world is the search for regulatory molecules and the identification of molecular targets to stimulate the body's endogenous regenerative potential. The concentrate of the deproteinized dermal layer of porcine skin (СDDLPS) is a new therapeutic agent with restorative properties, the action of which is directed on the induction of the self resources of cells. Aim. The assessment of the effect of СDDLPS on the proliferative activity of mammalian cells of different histogenesis in vitro. Materials and Methods. To determine the amino acid composition of the СDDLPS liquid chromatography and biochemical methods were used. The biological effects and mechanisms of action of the drug were investigated by cell culture and molecular biological methods. The research was carried out using stable cell lines: human keratinocytes (HaCaT cell line), porcine endothelial cells (PAE cell line), bovine kidney cells (MDBK cell line) and mouse fibroblasts (3T3A31 cell line). Results. The cells of the bovine kidney MDBK cell line were the most sensitive to the effect of the CDDLPS. Also, the obtained results suggest that, depending on the concentration, the drug not only stimulates cell proliferation by 10–30 %, but also significantly enhances biosynthetic processes in cells, in particular, protein synthesis by 20–40 %. Conclusions. CDDLPS is an effective and affordable therapeutic agent with restorative properties, the biological activity of which manifests itself in the activation of cell biosynthetic and proliferative potentials and is comparable to effects of some growth factors, in particular epidermal growth factor

Published: December 2020

Background:
The clinical spectrum of SARS-CoV-2 infection may vary from simple
colds to a severe acute respiratory syndrome, metabolic acidosis, septic shock, and multiple organ
failure. Current evidence indicates that the risk of severe illness increases with age, in the male sex,
and with certain chronic medical problems. Many people living with HIV have other conditions
that increase their risk.

Case presentation:
In the first 3 months of the pandemic, four patients with HIV were hospitalized
in our clinic because of COVID-19. The disease severity was mild in two patients with normal
CD4+ T count. However, one patient with a low CD4+T count died and the other developed retinal
detachment one month after discharge. The deceased patient had a malignancy.

Conclusion:
In this study, the effect of the immunological status of the patients on the course of
COVID-19 and the developing vascular complications was evaluated in 4 patients with HIV.

Published: December 2020

Background:
Speciation analysis is defined as the analytical activities of identifying and/or measuring the
quantities of one or more individual chemical species in a sample. The knowledge of elemental species provides more
complete information about mobility, bioavailability and the impact of elements on ecological systems or biological
organisms. It is no longer sufficient to quantitate the total elemental content of samples to define toxicity or essentiality.
Thus speciation analysis is of vital importance and generally offers a better understanding of a specific element.

Discussion:
Thorough speciation scheme consisting of sampling, sample preparation, species analysis and evaluation
were described. Special emphasis is placed on recent speciation analysis approaches including both direct and coupling
methods. A current summary of advantages and limitations of the various methods as well as an illustrative method
comparison are presented. Certain elements and species of interest are briefly mentioned and practical examples of
speciation applications in tobacco and other important economic crops are also discussed.

Aim/Conclusion:
This review aims to offer comprehensive knowledge about elemental speciation and provide readers
with valuable information. Many strategies have been developed for the determination of multiple elemental species in
tobacco and other important economic crops. Nevertheless, it is an eternal pursuit to establish speciation methods which
can balance accuracy, agility as well as universality.

Authors: Fedorova Natalia V. , Vu Ngoc Tuyen  , Yakovenko Igor A. 
Published: December 2020

Introduction. Problem solving focused on the protection of buildings and structures from progressive collapse and minimization of resources, needed for this purpose, is becoming increasingly important. In many countries, including Russia, this type of protection is incorporated into national regulatory documents, and, therefore, any research, aimed at developing effective ways to protect structural systems from progressive collapse under special actions, is particularly relevant. In this regard, the present article aims to formulate effective strength criteria for such anisotropic materials as reinforced concrete to analyze plane stressed reinforced concrete structures exposed to sudden structural transformations caused by the removal of one of bearing elements.
Materials and methods. To solve this problem, a variant of the generalized theory of plasticity of concrete and reinforced concrete, developed by G.A. Geniev, is proposed for application to the case of variable loading of a plane stressed reinforced concrete element. The acceptability of generalization of the strength criterion, pursuant to the theory of plasticity of concrete and reinforced concrete under static loading, and the applicability of this criterion to variable static-dynamic loading of reinforced concrete are used as the main hypothesis. An algorithm of an approximate method is presented as a solution to this problem; it allows to analyze the considered stress-strain state of plane stressed reinforced concrete elements.
Results. The numerical analysis of the obtained solution, compared with the results of the experimental studies, was used to evaluate the designed strength criterion for reinforced concrete elements located in the area where the column is connected to the girder of a monolithic reinforced concrete frame in case of a sudden restructuring of a structural system. It is found out that the qualitative nature of the destruction pattern of the area under research, obtained in experiments, corresponds to the destruction pattern, identified by virtue of the analysis performed using the proposed criterion.
Conclusions. The variant of the reinforced concrete strength criterion designated for the variable loading of a plane stressed reinforced concrete element and an algorithm for its implementation, based on the theory of plasticity of concrete and reinforced concrete developed by G.A. Geniev, is applicable to the analysis of a special limit state of reinforced concrete elements of structural systems of frames of buildings and structures.

Introduction. An engineering method is proposed for assessing salt formation on the surface of cement composites exposed to adverse operating conditions. The technique is based on the histogram method used to determine the dominant brightness of the half-tone image of scanned cement composites. The criterion for ranking composites is a relative dimensionless value –– a metric obtained by comparing the brightness of a grayscale image with the brightness level of white.
Materials and methods. We selected three types of compositions of composites in the amount of 21 items; each of them contains three samples –– a control sample and samples exposed to high humidity and positive temperatures for 15 and 45 days. Each composition is represented by a scanned raster image of the sample surface. The images are further subjected to digital processing using a software program written in the C++ programming language and the OpenCV technical vision library. This allows you to use the available methods and classes to develop algorithms to solve the problem in question and to convert a full-color RGB image to a grayscale image. Such images are used to analyze histograms, which determine the dominant level of brightness to determine the numerical metric for quantifying the salt formation on the surface of cement composite samples on the basis of their scanned images.
Results. A description of the software algorithm, used to detect salt formation on the surface of cement composite specimens that have passed performance tests under high humidity conditions at positive temperatures, is presented. The method of ranking cement composite samples using the values of their dominant brightness relative to the brightness of control samples is shown. The comparative analysis of the study is presented in the form of numerical data and explanatory diagrams.
Conclusions. Software modeling is employed to demonstrate the expediency of the methodology for the assessment of salt formation on the surface of cement composites and other building materials prone to salt formation.
Using XML schemas to structure information models of capital construction facilities
Authors: Volkov Sergey A. , Khripko Tatiana V. 
Published: December 2020

Introduction. Building Information Modeling (BIM) is an auspicious approach that supports management and exchange of semantically rich 3D models across design disciplines. Recently, BIM has gained widespread acceptance in the AEC industry, and it improves the efficiency and quality of the process by facilitating the early exchange of 3D building models. At different stages of the life cycle, a building information model is gradually refined from rough conceptual design to detailed individual components. The task is to develop mechanisms for machine verification (authentication) of data transmitted to/from different systems (for example, from a customer to an expert evaluation authority, from a contractor to the urban planning management information system or any other state information system) in the form of an information model of capital construction facilities or certain components of an information model.
Materials and methods. To substantiate the choice of the language employed to describe machine-readable documents, various use cases of XML schemas were analyzed, including the use of the Google Trends tool. Information systems, implemented in the Russian Federation, were also considered. Most of them use the W3C XML Schema language to describe XSD schemas.
Results. A consolidated list of XML schemas, necessary and sufficient to maintain stages of the life cycle of a capital construction facility in terms of interaction with the Urban Planning Management Information System is presented. To ensure interaction between the life cycle participants and state information systems, it is necessary to have the list of XML schemas approved at the federal level. The paper presents matrixes of scenarios for the application of XML schemas in the following coordinates: participants, life cycle stages.
Conclusions. XML schemas can be supplemented in respect of various stages of a life cycle of a capital construction faci-lity to be verified with due regard for further methodological approaches and changes in regulatory and technical acts; new approaches and the need for this supplementation must be substantiated.

Published: December 2020

Tiap jenis tanaman menghendaki syarat iklim dan tanah tertentu bagi pertumbuhan optimalnya. Menyangkut hubungan tanah-tanaman, terdapat hubungan erat antara keserasian tanah dengan faktor-faktor curah hujan. Walaupun pengaruh curah hujan terhadap pertumbuhan tanaman amat bergantung pada penyebaran dan tipe tanahnya, namun antara curah hujan dengan produksi tanaman terdapat hubungan umum yang kuat. Tanaman karet merupakan salah satu jenis tanaman hutan asli di lembah Amazon dengan ketinggian 200 mdpl dan dekat dengan ekuator. Daerah ini memiliki karateristik suhu antara 24 sampai dengan 28oC dengan curah hujan rerata 1500 – 2500 mm/tahun. Selama ini penentuan kualitas lahan kaitannya dengan produksi tanaman karet masih bersifat kualitatif dengan berbagai macam versi. Penelitian mengenai hubungan antara potensi klon, tanah, dan iklim dengan produksi tanaman karet secara kuantitatif belum banyak dilakukan. Tujuan penelitian ini adalah untuk mengetahui model potensi produksi karet klon tertentu pada wilayah dengan karateristik tanah dan iklim tertentu (spesifik wilayah). Asumsi yang digunakan untuk menentukan nilai optimal masing-masing adalah mengunakan persamaan regresi tipe kuadratik (regression quadratic model) Hasil penelitian menunjukkan hasil optimal untuk pertumbuhan tanaman adalah sebagai berikut yaitu 2640 mm curah hujan per tahun, 133 hari hujan pertahun, 3. bulan kering per tahun, 168 m dpl, 55 % jumlah fraksi lempung, dan drainase kriteria ke-3 atau weel drained. Hasil ini menunjukkan bahwa penggunaan persamaan matematsi dapat digunakan untuk menentukan potensi klon tertentu pada suatu wilayah dengan cepat dengan tingkat akurasi 79,19 %.

Minyak jarak pagar berpotensi digunakan sebagai bahan baku faktis coklat. Faktis coklat disintesis melalui reaksi vulkanisasi minyak nabati dengan sulfur (10-30%) pada suhu 130-150oC. Terbentuknya gel faktis coklat ditandai dengan terjadinya kenaikan suhu reaksi, timbulnya gas H2S, dan perubahan warna serta fasa pereaksi. Sintesis faktis coklat dilakukan dalam reaktor batch yang dilengkapi dengan pengaduk mekanis, jaket pemanas, dan alat pengendali suhu. Komposisi pereaksi dan kinerja reactor berpengaruh terhadap mutu faktis coklat. Faktis coklat bermutu tinggi akan berfungsi dengan baik sebagai bahan bantu olah kompon karet terutama untuk barang ekstruksi. Penelitian ini bertujuan mempelajari kinerja reaktor dalam pembuatan faktis coklat dari minyak jarak pagar pada skala pilot kemudian mengujicobakan faktis coklat dalam pembuatan selang gas LPG. Penelitian diawali dengan pembuatan faktis coklat dalam reaktor skala pilot berkapasitas 10-15 kg minyak/batch pada berbagai dosis penambahan ZnO. Faktis coklat yang diperoleh selanjutnya dikarakterisasi. Faktis coklat dengan karakteristik terbaik diujicobakan dalam pembuatan kompon dan vulkanisat selang gas LPG. Kompon selang gas LPG diuji karakteristik vulkanisasi sedangkan vulkanisat selang gas LPG diuji sifat fisika berdasarkan SNI 06-7213-2006. Hasil penelitian menunjukkan bahwa faktis coklat dengan spesifikasi mutu terbaik diperoleh pada kondisi reaktor berkapasitas 10 kg minyak jarak pagar/batch dan 0,5 bsm ZnO. Namun faktis coklat tersebut tidak mempengaruhi karakteristik vulkanisasi kompon dan sifat fisika vulkanisat selang karet secara signifikan.

Penyakit Gugur Daun Corynespora (PGDC) yang disebabkan oleh patogen Corynespora cassiicola (Berk & Curt) Wei., merupakan salah satu penyakit penting pada tanaman karet (Hevea brasiliensis). Klon-klon karet yang semula bersifat moderat terhadap serangan jamur ini, setelah beberapa tahun menjadi rentan dan terserang hebat. Hal tersebut diduga karena evolusi patogen menghasilkan ras baru yang lebih merusak. Oleh karena itu, informasi yang berkaitan dengan variabilitas patogen sangat diperlukan. Bahan yang dipakai dalam penelitian ini adalah isolat Corynespora cassiicola dari 7 daerah sentra perkebunan karet Indoneia yaitu Lampung, Bengkulu, Sumatera Selatan, Jambi, Sumatera Utara, Kalimantan Barat, dan Jawa Tengah. Prosedur kerja dalam penelitian ini meliputi penyiapan kultur isolat, ekstraksi DNA Corynespora cassiicola menggunakan metode modifikasi CTAB berdasarkan Situmorang (2002), analisis PCR dengan Inter Simple Sequence Repeat (ISSR), analisis data menggunakan UPGMA dalam program NTSYS, dan uji kelayuan daun menggunakan metode Nghia et al. (2007). Hasil analisis keragaman genetik isolat Corynespora cassiicola asal 7 wilayah sentra karet di Indonesia menggunakan marker ISSR menghasilkan 4 kelompok (4 ras) C. cassiicola, kelompok A (Ras 1) yaitu isolat asal Bengkulu, kelompok B (Ras 2) meliputi isolat asal Lampung dan Sumatera Utara, kelompok C (Ras 3) meliputi isolat asal Kalimantan Barat, Sumatera Selatan dan Jambi, dan kelompok D (Ras 4) yaitu isolat asal Jawa Tengah. Hasil uji kelayuan daun menunjukkan bahwa isolat-isolat Corynespora yang berada pada kelompok yang sama berdasarkan hasil analisis genetik, juga mempunyai tingkat infeksi (patogenitas) yang sama terhadap beberapa daun karet yang diuji. Isolat asal Jawa tengah (CJT) mempunyai rata-rata tingkat infeksi (patogenitas) tertinggi dibandingkan isolat yang lainnya. Tingkat infeksi terendah dari 7 isolat adalah pada klon RRIM 712 dan IRR 5, sedangkan tingkat infeksi 7 isolat Corynespora tertinggi terdapat pada klon BPM 24 dan PR 255.
