A Review of Updates on Vaccines and Treatment Options for Covid-19

The novel Coronavirus knew as Covid 19 or SARS-CoV-2, is a newly discovered virus responsible for the huge global pandemic infecting the human race at a deadly pace. This is an RNA enveloped virus that targets the human respiratory system severely while damaging other major systems. Covid 19 pandemic is similar to the severe acute respiratory syndrome related coronavirus (SARS-CoV) endemic and the Middle East Respiratory Syndrome Coronavirus (MERS-CoV), but this one is spreading at a fire-speed. The outbreak was known as pneumonia in the beginning; however, it became a threat later on, owing to its high contagion rate. The origin of this virus was sought to be from the seafood wholesale market, very popular in the city of Wuhan. This review has been put together to overview the disease, its etiology, clinical features and treatment methods. The focal point of this review is to highlight the current management of this disease.

A Review on Coronavirus

Coronavirus disease also termed as covid-19 or SARS-COV-2 infection has been declared as global pandemic disease by World Health Organization (WHO). The first case of covid-19 is reported at the local Huanan Seafood wholesale market in Wuhan city in Hubei in central chain at last of 2019. Covid-19 is rapidly spread throughout the world since December – 2019 from Wuhan city of China. Covid-19 patient has various symptoms like fever, cough, sore throat, breathlessness, fatigue and others. It is very necessary to identify the cases of covid-19 as soon as possible and isolate the suspected people and confirmed cases of Covid-19 to prevent the infection to other peoples.

PROBLEMS OF DEVELOPMENT OF THE ENERGY INDUSTRY IN THE ARCTIC TERRITORIES

The electric power industry is a branch of energy that includes the production, transmission and subsequent sale of electricity. Generating companies do not sell electricity directly to the population, but produce electricity and supply it to the wholesale market, where it is bought by sales companies, guaranteeing suppliers, independent energy marketing companies and large industrial consumers. Based on the results of a comparative analysis of the financial activities of energy marketing enterprises of the Russian Federation, problems are identified, imbalances and strategic plans for their development are determined. The results showed that the development of the energy industry as a whole depends on the financial activities of guaranteeing electricity suppliers. Unlike an independent power supply company, the activity of guaranteeing suppliers is less profitable and low-profitable, and the financial condition, in turn, is characterized by low solvency and financial stability. The authors have identified the weaknesses and strengths of this development. It is noted that the weakest side is the violation of the repayment terms of funds in settlements by electricity consumers, which leads to the formation of a negative financial result. The identified problems of financial development allow production us to form direction.

Demand Response Requirements from the Cultural, Social, and Behavioral Perspectives

Demand-side response programs, commonly known as demand response (DR), are interesting ways to attract consumers’ participation to improve electric consumption patterns. Customers are encouraged to modify their usage patterns in reaction to price increases through DR programs. When wholesale market prices are high or network reliability is at risk, DR can help to establish a balance between electricity generation and consumption by providing incentives or considering penalties. The overall objective of adopting DR programs is to increase network reliability and decrease operational costs. Nevertheless, the successful deployment of DR programs requires a set of conditions without which no success can be guaranteed. Implementing DR programs and achieving customers’ optimal power consumption behavior could be obtained through technical methods, such as using smart home appliances and big data techniques. However, even if each of these approaches is correctly implemented, they are not able to address all aspects of the problem. The findings of several studies demonstrate that, in addition to technical and economic concerns, social, cultural, and behavioral variables play a significant role in DR implementation. Therefore, this paper investigated the social, cultural, and behavioral variables as critical requirements for implementing DR programs. Furthermore, a theoretical framework and an analytical model of the elements impacting the electricity consumption are introduced that should be considered by the planners.

Predictive management of enterprise power consumption based on the SINGULAR SPECTRUM ANALYSIS method using recurrent forecasting

Modern energy strategies aimed at the development of energy industry presuppose a significant change in the structure of process of formation, transmission, consumption of electrical energy and increasing energy efficiency by introducing modern technologies at all stages. The growth of capacities of industrial enterprises in the conditions of wholesale market of electrical energy and capacity in the modern energy system determines the need for development technologies of predictive control of power consumption process of these enterprises. The introduction of such technologies at the control rooms of the operational management of enterprises will allow to reduce the number of human errors, the number of emergency stops of technological process, increase the reliability of power system mode, rationally manage the process of power consumption of enterprises. In this regard, forecasting the load demand and consumption is an important stage in the functioning and planning of modern power systems. An accurate, correctly compiled forecast is the key to effective management of energy consumption process and reliable operation of the enterprise. Forecasting errors lead to imbalanced supply-demand, which negatively affects operating costs, reliability and efficiency.

Management of local Citizen Energy Communities and Bilateral Contracting in Multi-Agent Electricity Markets

Over the last few decades, the electricity sector has experienced several changes, resulting in different electricity markets (EMs) models and paradigms. In particular, liberalization has led to the establishment of a wholesale market for electricity generation and a retail market for electricity retailing. In competitive EMs, customers can do the following: freely choose their electricity suppliers; invest in variable renewable energy such as solar photovoltaic; become prosumers; or form local alliances such as Citizen Energy Communities (CECs). Trading of electricity can be done in spot and derivatives markets, or by bilateral contracts. This article focuses on CECs. Specifically, it presents how agent-based local consumers can form alliances as CECs, manage their resources, and trade on EMs. It also presents a review of how agent-based systems can model and support the formation and interaction of alliances in the electricity sector. The CEC can trade electricity directly with sellers through private bilateral agreements. During the negotiation of private bilateral contracts, the CEC receives the prices and volumes of their members and according to its negotiation strategy, tries to satisfy the electricity demands of all members and reduce their costs for electricity.

The open-access telecommunication transmission network in the Canary Islands: an alternative proposal to the current management model?

Purpose This paper aims to study the competition problems and market failures in the Canary Islands and propose an alternative management model for the telecommunication transmission network. This model is based on a wholesale-only open-access transmission network, available to all the retail service providers of this region, and managed by a unique entity subject to regulation with cost-based prices. The proposal hopefully will help to debate about the implementation of certain regulatory models in the network industries, concerning telecommunication submarine cables connecting archipelagos. Design/methodology/approach An empirical approach has been used, based on the observation and analysis of the regulatory policies applied to the wholesale transmission networks in the Canary Islands, Azores and Madeira archipelagos. Findings Results show a persistent margin squeeze situation on the retail broadband market in the Canary Islands, due to the pricing strategy on the Spanish mainland-Canaries wholesale market, which is, in turn, delaying the entry of alternatives and the level of development and efficiency of competition. The risk of duopoly collusion is also present on this wholesale market. Additionally, public aids will be needed to replace the systems connecting with the non-capital islands and to provide redundancy to El Hierro. The alternative proposal might help preventing the above. Eventually, several insights are considered for further investigation. Originality/value Little attention has been paid to this topic in the literature, regarding the analysis of regulatory policies applied over fiber optic submarine cable infrastructures in fragmented territories like archipelagos. Consequently, an empirical analysis has been accomplished to emphasize this research work, based on the regulatory policies adopted.

The Working Conditions and Optimisation of a Large Rainwater Harvesting and Treatment System in an Area at a Risk of Erosion

Rainwater harvesting and treatment systems (RHTS) are used in many places around the world as a part of sustainable water management. They decrease the risk of overloading the sewage network and environmental pollution. The efficiency and reasonableness of using such solutions in specific erosive conditions are not sufficiently understood. The aim of the study was to evaluate the operation of RHTS, receiving effluents from the wholesale market and fuel station (twenty years of observations). The studied system is located in an area endangered by water erosion. In the study period, due to the accumulation of erosive phenomena, it was necessary to optimise the system (including the installation of new devices and increasing the capacity of reservoirs). The analyses referred to the stability and work safety of the most important equipment and water treatment efficiency. The quality of water in the reservoirs was measured before and after the modernisation of the system. Selected physical, oxygen, biogenic and salinity indicators were determined in the water. During the study, RHTS had a positive effect on the quality of rainwater runoff – the values of many contaminants were reduced (RHTS 1: suspended solids, nitrogen, iron, potassium; RHTS 2: conductivity, suspended solids, nitrogen). Design and operational errors were noticed that in the long run may contribute to deteriorating the operational efficiency and even lead to a building collapse (intense erosive phenomena). This study clearly demonstrates that building a rainwater management system is a highly site-specific issue.
