AWARENESS LEVEL AND INVESTMENTS IN MUTUAL FUNDS - A STUDY
Authors: Revankar Ashok
Published: November 2020

To earn a return on surplus and idle funds, generating a specified amount to meet certain goals in future or making provisions for future contingencies investment is necessary. To protect the funds to meet these objectives investment must be made with knowledge and at most care. But large number of people does not have sufficient knowledge about various investment avenues. The awareness level and savings/investment pattern differs from individual to individual. In our country very less number of people invest in mutual funds and awareness level about these is very poor comparatively to other countries. The amount saved must be invested in one or the other security, it should not be kept idle. But to take good investment decision financial knowledge is a must. A disciplined financial plan will definitely help the individuals to take decisions relating to savings and investments to meet their financial goals. Efforts should be made to attract more number of people towards mutual funds to invest their surplus funds.

Authors: Akhtaruzzaman M. , Bari S. M. Sadakatul , Hossain Syed Akhter , Rahman Md. Mahbubur
Published: November 2020

In satellite communication, Link Budget analysis is the most important part to determine gains and losses of signals from the transmitter to the receiver. Most importantly, it investigates system performance and optimum power which must be received at the receiver channel. In some cases, this information could be generated, saved for past data analysis, and share with peer users which are not found in existing web tools. Thus, it is obvious to design a new Link Budget calculator with users, database, and data retrieval support. This work focuses on designing a Link Budget web tool for X-band satellite communication through literature study and comparative analysis. The X-Band calculator is designed based on HTML, PHP, Javascript, and MySQL by ensuring several security issues, and can be accessed through mobile devices. This paper also focuses on the necessary equations of Link Budget for Uplink (Tx); Satellite; Downlink (Rx); Azimuth, Elevation, Distance analysis; and Rain attenuation. Though, comparative assessments among various web tools show some fluctuations, overall outputs show satisfactory results with small % of Errors (PoE) ensuring reliability and viability of the proposed X-Band tool for practical use.

Application of Convex Optimization Results of DE FINETTI’s Problem for Proportional Reinsurance (A Case Study of CAARAMA Insurance Company in Algiers)
Authors: Cheraitia Zahra , Kherchi Medjden Hanya
Published: November 2020

The objective of this research is to find the optimal retention level for a proportional reinsurance treaty based on the results of the convex optimization developed in De Finetti’s model. The latter makes it possible to determine the level of retention that achieves the expected profit by the insurer while minimizing claims volatility.

The convex functions appear abundantly in economics and finance.  They have remarkable specificities that allow actuaries to minimize financial risks to which some institutions are exposed, especially insurance companies. Therefore, the use of mathematical tools to manage the various risks is paramount. In order to remedy the optimization problem, we have combined the probability of failure method with the "De Finetti" model for proportional reinsurance, which proposed a retention optimization process that minimizes claim volatility for a fixed expected profit based on the results of the non-linear optimization.

Uncertainty of the hourly average concentration values derived from
non-continuous measurements
Authors: Haszpra László , Prácser Ernő
Published: November 2020

Abstract. Continental greenhouse gas monitoring networks extensively use tall towers for higher spatial representativeness. In most cases, several intakes are built along the tower to give information also on the vertical concentration profile of the components considered. Typically, a single gas analyzer is used, and the intake points are sequentially connected to the instrument. It involves that the continuous concentration signal is only sampled for discrete short periods at each intake points, which does not allow the perfect reconstruction of the original concentration variation. It increases the uncertainty of the calculated hourly averages usually used by the transport and budget models. The purpose of the study is to give the data users an impression on the potential magnitude of this kind of uncertainty, as well as how it depends on the number of intakes sampled, on the length of the sampling period at each intake, on the season, and on the time of the day. It presents how much improvement can be achieved using linear or spline interpolation between the measurement periods instead of the simple arithmetic averaging of the available measurements. Although the results presented here may be site-specific, the study calls attention to the potentially rather heterogeneous spatial and temporal distribution of the uncertainty of the hourly average concentration values derived from tall-tower measurements applying sequential sampling.
Improvements to a laser-induced fluorescence instrument for measuring SO2: impact on accuracy and precision
Authors: Rickly Pamela S. , Xu Lu , Crounse John D. , Wennberg Paul O. , Rollins Andrew W.
Published: November 2020

Abstract. This work describes improvements made to the in-situ laser induced fluorescence SO2 instrument as originally described in Rollins et al. (2016). We report measurements of the SO2 fluorescence emission spectrum. These measurements allow for the determination of the most appropriate bandpass filters to optimize the fluorescence signal while reducing the instrumental background. Because many aromatic species fluoresce in the same spectral region as SO2, fluorescence spectra were also measured for naphthalene and anisole to determine if ambient SO2 measurements may be biased in the presence of such species. In addition, the 216.9 nm laser linewidth was decreased in order to increase the online/offline signal ratio which in-turn increases the precision of the measurement. The effects of these improvements on the instrumental sensitivity were determined by analyzing the signal and background of the instrument using varying optical bandpass filter ranges and cell pressures and calculating the resulting limit of detection. As a result, we report an improvement to the instrumental sensitivity by as much as 50 %.

Authors: Silva Samuel , Simozo Fabricio , Murta Junior Luiz , Tinós Renato
Published: November 2020

Displasia Cortical Focal (DCF) é um tipo de lesão cerebral que é a principal causa de Epilepsia Refratária em crianças. A cirurgia é uma alternativa para o tratamento de pacientes com DCF. No entanto, a identificação correta das regiões com DCF no cérebro é necessária. A identificação de DCF em Imagens de Ressonância Magnética usando Redes Neurais Convolucionais (CNNs) é investigada. A CNN classifica pequenas regiões das imagens (janelas), que podem permitir a identificação da localização do DCF. O método baseado na CNN é comparado com a abordagem tradicional, em que um Perceptron Multicamadas (MLP) é empregado usando filtros predefinidos para a extração de características da imagem. A CNN apresenta resultados melhores que o MLP. A CNN apresenta alta sensibilidade. No entanto, a especificidade é baixa, indicando que um conjunto de dados maior é necessário para treinar a CNN.

Authors: Candido Raquel , Lama Rafael , Chiari Natália , Nogueira-Barbosa Marcello , Azevedo Marques Paulo , Tinós Renato
Published: November 2020

Non-traumatic Vertebral Compression Fractures (VCFs) are generally caused by osteoporosis (benign VCFs) or metastatic cancer (malignant VCFs) and the success of the medical treatment strongly depends on a fast and correct classification of VCFs. Recently, methods for computer-aided diagnosis (CAD) based on machine learning have been proposed for classifying VCFs. In this work, we investigate the problem of clustering images of VCFs and the impact of feature selection by genetic algorithms, comparing the clustering i)with all features and ii)with feature selection through the purity results. The analysis of the clusters helps to understand the results of classifiers and difficulties of differentiating images of different classes by an expert. The results indicate that features selection improved the separability of clusters and purity. Feature selection also helps to understand which attributes are most important for analysing the images of vertebral bodies.

Published: November 2020

Hospitals and intensive care units are straining to provide care for a large surge of patients with coronavirus disease 19 (Covid-19). Contingency plans are being made for the pos­sibility that resources for lifesaving care, including mechanical ventilators, will be in short supply. Covid-19 is more severe and more likely to be fatal in older persons. Dementia is one of the commonest severe comorbidities of aging. Persons with dementia are vulnerable and often need the support of others to make their voices heard. This commentary, created by a task force commissioned by the Alzheimer Society of Canada, provides guidance for triaging persons with dementia to scarce medical resources during the Covid-19 pandemic.
Using the Clinical Frailty Scale in Allocating Scarce Health Care Resources
Authors: Rockwood Kenneth , Theou Olga
Published: November 2020

The key idea behind the Clinical Frailty Scale (CFS) is that, as people age, they are more likely to have things wrong with them. Those things they have wrong (health deficits) can, as they accumulate, erode their ability to do the high order functions which define their overall health. These high order functions include being able to: think and do as they please; look after themselves; interact with other people; and move about without falling. The Clinical Frailty Scale brings that information together in one place. This paper is a guide for people new to the Clinical Frailty Scale. It also introduces an updated version (CFS version 2.0), with revised level names (e.g., “vulnerable” becomes “living with very mild frailty”) and minor edits to level descriptions. The key points discussed are that the Clinical Frailty Scale assays the baseline state, it is not widely validated in younger people or those with stable single-system disabilities, and it requires clinical judgement. The Clinical Frailty Scale is now commonly used as a triage tool to make important clinical decisions such as allocating scarce health care resources for COVID-19 management; therefore, it is important that the scale is used appropriately.
Die Verkörperung der Welt
Authors: Ivanov Paola
Published: November 2020

In the Swahili societies on the East African coast there is a remarkable openness for people, ideas and goods that come from “outside”. This also applies to Zanzibar. Especially in the female sphere – in Islamic societies the "innermost" sphere – the existential social values of beauty and respect are generated by goods coming from outside. This becomes apparent especially in ceremonies such as weddings. Paola Ivanov sheds new light on how outer worlds in Zanzibar become part of one's own person and society. She explains the aesthetic practices forming people, identities and social relationships. The study thus enables a differentiated understanding of processes of interweaving and crossing borders and emphasizes the central role of the female sphere in Zanzibar's Muslim society.

Authors: Gurbanov Guseyn R. , Pashaeva Saida M. , Adygezalova Mekhpara B.
Published: November 2020

Using the gravimetric method, the inhibitory efficiency of the combined inhibitor with respect to hydrogen sulfide and carbon dioxide corrosion of St3 steel in model-produced water MI was studied. Corrosion tests were carried out in 0.5 l sealed vessels on St3 samples of size 30×20×1. Gossypol resin + MARZA was used as a multifunctional combined inhibitor. Diesel fuel and kerosene were used as solvent. It has been established that the protective effect of using a multifunctional combined inhibitor in formation water with oil containing hydrogen sulphide and carbon dioxide using kerosene as a solvent ranges from 75 to 96 and for diesel as 80 to 100. The combined inhibitor allows to achieve in the MI medium containing hydrogen sulfide and carbon dioxide in the process of daily testing the corrosion rate of steel is about 0.04 g/ m2∙h only in a concentration of not less than 70 mg/l. However, with an increase in the duration of the test by an order of magnitude, a similar corrosion rate is observed already at an inhibitor concentration of 50 mg/l. The same is characteristic of carbon dioxide and hydrogen sulfide - carbon dioxide solutions. The bactericidal properties of the combined inhibitor with respect to two types of Desulfovibriodesulfuricans and Desulfomicrobium sulfate-reducing bacteria were studied. The effect of the inhibitor on the number of bacterial cells and the formation of hydrogen sulfide in Postgate nutrient medium “B” was evaluated. It has been shown that the combined inhibitor exhibits a bacteriostatic effect on to sulphate-reducing bacteria. It was revealed that the degree of suppression of the number of microorganisms Desulfovibriodesulfuricans at a concentration of the combined inhibitor 100.0 mg/l is higher than Desulfomicrobium. In the latter case, to achieve this effect, 120.0 mg/l concentration of the combined inhibitor is required. The studied combination inhibitor causes inhibition of hydrogen diffusion in steel St3 in the MI medium saturated with H2S and CO2 separately and together, and contributes to preserving the ductile properties of the steel St3 after exposure to solutions compared to non-inhibited media.

Published: November 2020

The article presents the results of a study of high-temperature and electrochemical corrosion of Zn0.5Al alloy doped with calcium in the various media. The thermogravimetric method was used to study the interaction of the Zn0.5Al alloy doped with calcium with atmospheric oxygen in the temperature range 523–623 K in the solid state. The kinetic and energy parameters of the process of high-temperature oxidation of alloys are determined. The process of high-temperature oxidation of Zn-Al-Ca alloys system is characterized by a monotonic decrease in the true oxidation rate and an increase in the effective activation energy when the alloying component in the initial Zn0.5Al alloy is up to 1.0 wt% doping with zinc-aluminum alloy 0.5 and 1.0 wt%. Calcium shows a slight increase in the oxidation rate of alloys. It was revealed that the oxidation process of the studied alloys with oxygen of the gas phase obeys the hyperbolic law. It was found that calcium supplements in the range of 0.01 - 0.1 wt%. The oxidizability of the initial Zn0.5Al alloy is reduced significantly, and the oxidation products of the alloys were ZnO, Al2O3, Al2O3 ∙ ZnO, CaO, Al2O3 ∙ CaO. By potentiostatic methods in the potentiodynamic mode with a potential sweep speed of 2 mV/s, it has been shown that for all samples of the Zn0.5Al-Ca alloys system in the acidic, neutral, and alkaline media, electrochemical potentials of corrosion, pitting formation, and repassivation are shifted to the region of negative values. It was revealed that zinc-aluminum alloys doped with calcium are most resistant to pitting corrosion in all studied media, respectively, in acidic (0.01n.), neutral (0.03-, 0.3-, 3.0 wt%) and alkaline (0.01n.) electrolytes of HCl, NaCl and NaOH. It has been established that calcium additions in the range of 0.01 - 0.1 wt.% reduce the corrosion rate of zinc-aluminum alloy Zn0.5Al by a factor of 2–3. Calcium alloys are recommended as anodic coatings and protectors for corrosion protection of steel products and structures operating at high temperatures.

Aim. An ancient dream of hemp farmers was the breeding of new varieties of monoecious hemp. The unexpected problem of hemp production has arisen the need to attract scientific breeding to create the world's first non-narcotic highly productive hemp. Methods. Measures of unconscious selection of plants in the period of threshing under the name "sichka" and "molochka" served as a prototype. The development of breeding methods was carried out in parallel to solve the problems of increasing the fiber content in the stems, the simultaneity of maturation, the creation of a new monoecious form of hemp, increase the yield of fiber and seeds and the removal of narcotically neutral new varieties. Results. Breeders of different generations researched and created new high-performance non-narcotic varieties of dioecious, simultaneously ripening and monoecious hemp varieties such as Hlukhivski 1, Hlukhivski 10, US 6, USO 1, USO 14, USO 16, Dniprovski odnodomni 6, USO 31, Hliana, Hlesia and others. Conclusions. Many years of cultivation of hemp and the creation of all new varieties of them showed that with a long substantiated study of this culture it is possible to obtain new information as yet unknown, due to the versatile differentiation of this culture by sexual types, openly showing the morphological and biological features of the sexes, representing gender forms that gradually change into one another, bringing researchers closer to new discoveries in genetics. Keywords: hemp, hemp forms, methods and ways of breeding, breeding varieties.

Aim. The aim of the study was to investigate genetic variability of gliadin-coding loci Gli-A1, Gli-B1, Gli-D1 in Ukrainian winter common wheat landraces and obsolete varieties. Methods. APAG electrophoresis of gliadin was used to identify genotypes at Gli-1 loci. Results. Diversity at the Gli-1 loci of 41 winter common wheat landraces, including local varieties Krymka, Banatka, Girka, Theyka, and 13 obsolete winter common wheat varieties, were studied. A total 31 gliadin alleles (including new 7 alleles) were revealed. There are 11 alleles at the Gli-A1 loci, 14 - at the Gli-B1, 6 -at the Gli-D1. Differences in frequencies of gliadin alleles were established. Conclusions. The high level of allelic variation at the Gli-1 loci was observed in Ukrainian winter common wheat landraces. Predominant alleles were revealed: Gli-A1m (46,8 %), Gli-A1d (21 %), Gli-B1b (47,1 %), Gli-D1g (45,8 %), Gli-D1a (33,3 %), Gli-D1j (13,9 %). In genotype of modern Ukrainian winter common wheat are present only 3 of them - Gli-B1b, Gli-D1g, Gli-D1j, which positively relate to dough quality.

Aim. To evaluate the activity of cryopreserved boar ejaculated spermatozoa under different thawing protocols to optimize biotechnological approaches in pig reproduction based on the genetic material of the Institute of Animal Breeding and Genetics nd. a. M.V. Zubets of National Academy of Agrarian Science of Ukraine. Methods. Cryopreserved ejaculated boars' sperm was thawed in three different ways. Biotechnological, cryobiological and morphological methods were used to assess the viability of the sperm. Results. We noted the individual feature of semen quality of the studied boars, which affects its suitability for cryopreservation and quality indicators after thawing. It was found that in liquefied boar sperm (sperm activity on average is 86.7%) after its centrifugation and three-hour equilibration at + 4 °C sperm activity decreased by an average of 25.0%. In order to improve the quality of cryopreserved sperm, it was thawed under different conditions. The highest activity of spermatozoa in thawed sperm of boar No. 225 of Myrhorod pig was at the level of 25.0% at the thawing temperature + 70 °C, and the thermal resistance and heat resistance were 70.0% and 60.0%, respectively. Conclusions. During this study was noted that there are peculiarities of boar semen at breed and individual level, which influence its ability to tolerate cryopreservation. Keywords: sperm, in vitro cultivation, cryobank, cryopreservation, boars.

We determined differential gene expression in response to high glucose in lymphoblastoid cell lines derived from matched individuals with type 1 diabetes with and without retinopathy. Those genes exhibiting the largest difference in glucose response were assessed for association with diabetic retinopathy in a genome-wide association study meta-analysis. Expression quantitative trait loci (eQTLs) of the glucose response genes were tested for association with diabetic retinopathy. We detected an enrichment of the eQTLs from the glucose response genes among small association p-values and identified folliculin (FLCN) as a susceptibility gene for diabetic retinopathy. Expression of FLCN in response to glucose was greater in individuals with diabetic retinopathy. Independent cohorts of individuals with diabetes revealed an association of FLCN eQTLs with diabetic retinopathy. Mendelian randomization confirmed a direct positive effect of increased FLCN expression on retinopathy. Integrating genetic association with gene expression implicated FLCN as a disease gene for diabetic retinopathy.

Effective on‐demand release of therapeutics at an intracellular drug supply hub, the cytosol, is among the important steps for successful drug delivery. To improve cytosolic drug release, this study selects diselenide because the bond is cleaved by both glutathione (GSH) and reactive oxygen species (ROS) in the cytosol. Specifically, upon diselenide cleavage, the levels of GSH or ROS are reduced, resulting in decreased or increased cell viability and either the synergistic or antagonistic death of cancer cells with an anticancer drug, respectively, because GSH and ROS trigger two conflicting functions (i.e., antioxidant vs prooxidant activity). Thus, this study designs a diselenide‐based drug carrier to determine which trigger is the major cause of diselenide degradation, how the disrupted balance between GSH and ROS levels influences cell viability and drug efficacy, and whether the combined use of a diselenide drug carrier and a drug has a synergistic or antagonistic effect. Using a multiple diselenide‐containing nanoparticle (MSePCL‐NP), the study shows that diselenide is cleaved to a greater extent by GSH than by ROS; MSePCL‐NP induces a greater decrease in the viability of cancer cells, but not normal cells; a combination of DOX@MSePCL‐NP synergistically kills cancer cells and inhibits tumor growth in vivo.
