A comparative study on the impact of COVID-19 on European countries[ ]


With the help of three developed European countries, this research assessed whether the countries would be able to fend themselves off from the negative effects of this pandemic. Factors such as economic growth rate, GDP, sectoral distribution, and specialization were considered, which helped in examining the success of the implemented policies. Each country’s individual demographic and geographic conditions were taken into account to minimize bias towards one country.

Nidovirales: evolving the largest RNA virus genome [ ]


Hydroxychloroquine is a 4-aminoquinoline with immunosuppressive, antiautophagy, and antimalarial activities. Although the precise mechanism of action is unknown, hydroxychloroquine may suppress immune function by interfering with the processing and presentation of antigens and the production of cytokines. As a lysosomotropic agent, hydroxychloroquine raises intralysosomal pH, impairing autophagic protein degradation; hydroxychloroquine-mediated accumulation of ineffective autophagosomes may result in cell death in tumor cells reliant on autophagy for survival. In addition, this agent is highly active against the erythrocytic forms of P. vivax and malariae and most strains of P. falciparum but not the gametocytes of P. falciparum.

THE NEW NUMERICAL METHOD[ ]


Mathematics surpasses the level of just arithmetic. With mathematics you do not only work with numbers, but also with letters so we can make formulas (and equations) and work with them. With these formulas we can express relations a lot easier. Mathematics enables us to communicate without useless human language. Just adding, multiplying, is-equal-to, etcetera. A language that is understood all over the world. The mathematical symbols are the same, whether you speak English, French, Spanish or Dutch.

SOLAR PHOTO-VOLTAIC SYSTEM EFFICIENCY IMPROVEMENT USING UNITARY-AXIS ACTIVE TRACKING SYSTEM[ ]


Low solar-electrical energy output conversion efficiency is a major limitation in the use of solar photovoltaic (PV) systems for power generation. This work aims at determining the degree of effectiveness of a unitary axis solar active tracker. In this work, a unitary axis solar active tracking system by which more energy from the sun can be harnessed was designed and setup. An arduino Uno (Atmega 328p) which is an Atmel microcontroller based board, was used as the main controlling unit to control the operations in the system.

Comparisons of proximate composition, sensory evolution, physiochemical, total phenol, flavanoid content and Antioxidant effect of mixed fruit bar from mango, pineapple and papaya.[ ]


Fruits contain various macronutrient as well as natural antioxidants and secondary metabolites which play an important role in human health. Mixed fruit bar has been proposed as a convenient substitute for fresh fruit. In this study, proximate analysis, various physiochemical such as lycopene, anthocyanin, β-carotene content, flavanoid content, total phenolic content and antioxidant activity of various fresh fruit and mixed fruit bars (mango, pineapple, and papaya) were compared. Proximate composition was determined by AOAC, 1998 method, total phenolic content of the extracts was determined using Folin-Ciocalteu assay, and antioxidant capacity of the extracts was determined by 1,1-diphenyl-2picryl hydrazyl (DPPH) scavenging assay. Among the four sample S1, S2, S3 and S4, the sample S3 secured highest score for overall acceptability and ranked as “like very much” by a taste testing panel.

Assessing the Role played by Technical Universities in Sierra Leone[ ]


There is necessity for skilled human resource development and practicality for the overall development of any country to improve. This cannot be over emphasized as Technical and vocational education is the one the produces harmonious, sustainable national development. Productivity of a nation is seriously influenced by this technical and vocational education and training of different courses in the polytechnics. It is though, certain that the polytechnic provides most of the skilled labour of the workforce which help the country to succeed and develop worldwide.

The Random Walk Behavior and Market Efficiency of Nepalese & Indian Stock Markets[ ]


This study examines the weak-form market efficiency of Nepalese stock market and Indian stock market. Daily returns for Nepalese and Indian stocks are examined for random walks using serial correlation coefficient, runs tests, Augmented Dickey-Fuller, Phillips-Perron unit root tests and multiple variance ratio tests. The results, which are based on the different approaches employed, indicate that none of the markets are characterized by random walks and hence are not weak-form efficient, even under some less stringent random walk criteria.

A Comparative Study on Efficiencies of Variants of Convolutional Neural Networks based on Image Classification Task[ ]


Deep neural networks have shown their high performance on image classification tasks but meanwhile more training difficulties. Due to its complexity and vanishing gradient, it usually takes a long time and a lot of computational resources to train deeper neural networks. Deep Residual networks (ResNets), however, can make the training process easier and faster. And at the same time, it achieves better accuracy compared to their equivalent neural networks. Deep Residual Networks have been proven to be a very successful model on image classification.

Gene Drive Systems: Suitable Solution for Vector Borne Diseases[ ]


Gene-drive systems enhance the likelihood of a sequence passing on to future generations and eventually through a local population and ultimately to all connected population of a species. While genetically engineering an organism means that only that specific organism will carry the specific modifications, using gene drive systems ensures that their offspring will carry the same modifications too which will eventually spread throughout the entire population.

Recent Advances in Apricot Dehydration[ ]


Fruits like apricot have high water activity and they are highly heat sensitive and easily degradable. About 50% of the apricot fruit produced in a year getting wasted due to the short harvest season and the sensitivity to storage even at refrigerated conditions. For that drying methods are used and dehydration must not only be efficient and economic but also yield high-quality products based on flavour, nutrients, colour, rehydration, uniformity, appearance, and texture.

The Benefits and Characteristics of IPv6[ ]


Internet has developed exponentially over years and has become an identity. To define a system using internet unique there are addresses provided known as IP address. Rapid expansion of the Internet has created a “success disaster” in terms of IP addresses. The used technology to address systems uniquely was IPv4 but with the time, address provided by IPv4 is soaking. Here IPv6 comes into picture. IPv6 can provide more address as compared to IPv4. Existing studies have discussed the notation that IPv6-centric next generation network are widely developed and applied. In order to gain a good understanding of IPv6, this paper revisits several benefits and characteristics of using IPv6.

Design & Development of Automatic Seed Sowing Machine by Utilizing Solar Energy[ ]


In the current scenario, most of the countries do not have sufficient skilled man power in the agriculture sector and it affects the growth of developing countries. So it’s a time to automate the agricultural sector to overcome this problem by using upgraded technology for cultivation activity. To meet the future food demands, the farmers have to implement the new techniques which will not affect the soil texture but will increase the overall crop production. The aim of this project is to design and develop a solar operated seed sowing machine.

Dynamic Nexus between Economic Growth and Total Reserve and Aggregate Consumption Expenditure: An ARDL Approach[ ]


This paper tries to see the association among reserve, aggregate consumption expenditure, and economic growth by employing the autoregressive distributed lag (ARDL) model. Both the explanatory variables such as consumption and reserve are statistically significant. The consumption expenditure is strongly affecting the economic growth both in the short and long-term. Performing the ADF and PP test the variables are integrated order of one I(1). The bound test confirmed that the long-term association exists between the variables. There ¬is a unidirectional association found among the variables.
