This study investigates the significance and profile of Listed Property Companies (LPCs) in 10 African countries namely; Botswana, Egypt, Kenya, Mauritius, Morocco, Nigeria, South Africa, Tunisia, Zambia, and Zimbabwe respectively for the period of 10 years from 2006 to 2015., the profile and some key indicators of each respective country has been identified to determine the significance of each respective economy. The study uses secondary data obtained from Thompson Reuters DataStream to extract the number of companies in each country and their respective profiles. Descriptive statistics were used to analyze 64 Listed Property Companies using simple percentages. The study revealed that most of the African countries are Opaque with very few semi-transparent such as Kenya, Mauritius, and Botswana with the exception of South Africa which is the only transparent, the study further revealed that most of the companies are established between 2010 to 2015. Egypt has the highest number of property companies 29 represented by 45.31 % followed by South Africa with 16 Listed property Companies Represented by 25 % while Nigeria, Kenya and Zambia have the least number of companies with 1 each represented by 1.56%.
The article is devoted to the problems, hindering the development of Ukraine’s merchant fleet. The direction of the state policy, which should help in strengthening the position of Ukraine as a maritime state, creation of favorable conditions for the achievement of the goals and solving the tasks of development of maritime activity are grounded. The author presents some ways of solving problems that impede the development of Ukraine’s merchant fleet. The thesis is that the dominant position will belong to the merchant navies of those states which successfully balance competing aspects of the shipping industry (the interests of shipowners, crews, flag states, ordinary inhabitants of the planet who are interested in preserving the environment, etc.) while remaining competitive. This circumstance makes it necessary to put into practice the measures of the state, aimed to support the merchant fleet. Only in such way it will be possible to restore the “lost” deadweight of the country’s merchant fleet in the near future.
Kware Lake provides life to various forms of aqua flora and fauna, livelihood for fishermen community and food for the local populace. The study was conducted to evaluate nutrient dynamics of the lake’s sediment for a period of 12 months (June 2014 to May 2015). Results reveal that some of the variables studied did not show any variation due to space and time but electrical conductivity (EC), phosphate (PO43-), potassium, sodium and clay texture were able to vary according to months, seasons and stations. They recorded range of 101.3-113 µs/cm, 0.97-1.24 g/Kg, 0.29-0.37 g/kg, 0.62-0.77 g/kg, and 13-14 g/kg respectively. Results therefore suggest and confirmed that sediment has a high accumulation of phosphate, due to decomposition on the sediment bed and low nitrate level in sediment than in surface water.
The use of synthetic fibres resulted in environmental degradation and the growing interests towards the utilisation of readily available agricultural fibres as a potential replacement for synthetic fibres. This research aims to produce a ceiling board composite from piliostigma thonningii particulate using styrofoam adhesive binder. The board was produced from the readily available materials leading to the low cost of production. The composition has a formulation of fibre/binder mixing ratios (2:1, 1:1, 1:2 w:w), pressures of (100, 300, 500 kg/m2) and temperatures of (30, 65, 100 °C) respectively. The process was successfully modelled and optimized using a Box–Behnken design method. The optimal conditions for the piliostigma thonningii board were found to be fibre/binder mixing ratio of 1:1 w:w, pressure of 500 kg/m2 and temperature of 92 °C yielded response values of density (151.5 kg/m3), water absorption (9.04 %), tensile strength (16.9 N/m2), thermal conductivity (0.11 W/mK). Hence the board has greater insulating properties and good potential to be used as a ceiling board.
Transition metals are highly sought after in electrode construction due to their eventual electrocatalytic effects. In this context, this work presents the study of several metal oxide modified electrodes focusing in the evaluation of their electrochemical features through voltammetry and Electrochemical Impedance Spectroscopy (EIS). Moreover, a predictive statistical model was also developed using LASSO regression. Henceforth, glassy carbon electrode (GCE) and carbon paste electrode (CPE) were used to establish correlations between the herein studied modifications, namely: PdO@CPE, TiO2@CPE, and LaFeO3@CPE. Results evidence that metal oxide modified electrodes may increase signal detection through electrocatalytic effects, however, the herein developed model evidenced that surface area plays a major role in electrode response through voltammetry.
As it is known, the phenomenon of corruption, is characteristic of virtually all spheres of human activity. Therefore, it would be logical to assume that anti-corruption legislation will accordingly prohibit corruption acts for all entities that are capable to objectify the fact of the dominance of corruption in objective reality. This question is extremely relevant, taking into account the following fact: if there are groups of subjects that by their actions (or inaction) cause corruption, but they are not considered by the legislator as subjects of corruption crimes, accordingly, one can speak neither about the proper effectiveness of anti-corruption legislation, nor about the proper quality of anti-corruption activities. At the same time, analyzing the laws of various states, we can conclude that there is still no unified list of subjects of corruption crimes in the world, which, on the one hand, is associated with a different approach to understanding the phenomenon of corruption, and, on the other hand, makes it impossible to formulate a corresponding unified definition. In the article the author attempts to systematize an exhaustive list of subjects of corruption crimes under the current legislation of Ukraine. The corresponding systematization of the subjects of corruption crimes is preceded by an outline of the general idea of the subject of corruption crime in Ukraine, within which, the author identifies the main characteristics of these subjects. At the same time, based on the division of crime subjects in the theory of the criminal law into general and special ones, the “Generalized interpretation of the structure of subjects of corruption crimes under the legislation of Ukraine” is formulated for the first time by dividing possible participants of corruption relations, respectively, into groups of general and special subjects of these crimes. The group of general subjects of corruption offense covers all individuals, capable of being considered subjects of a crime in principle. The group of special subjects of corruption offense is a group of people, which includes the following types of subjects: a public official; a person, equivalent to a public official; top managers of legal entities of private law and individuals, providing services; candidates for public elective posts; separate categories of individuals, performing a special role in the life of society and state.
The paper considers the prospect of using renewable energy sources in the country’s fuel balance. An important source of energy is biomass, which is characterized by renewability, accessibility, versatility, minimal impact on the environment, transportation, accumulation and storage. At the same time, biomass has a number of disadvantages: a heterogeneous structure with a broad fractional composition, with low bulk density and energy density, and high initial humidity, and often ash content. To improve the thermal characteristics and to increase the energy efficiency of using biomass, it is subjected to physical, biochemical or thermochemical conversion. An effective way to improve the thermal characteristics of the original biomass is to compress it in a mixture with other combustible materials, for example, organic waste from agriculture, oil refining, coal, paper industry, which allows, in particular, to solve environmental problems as well. An estimation of the possibility of using organic waste from livestock and poultry farming in a composition with waste biomass of vegetable origin is conducted. The results of calorimetric studies of the calorific value of samples of such composite fuel, based on husk of sunflower seeds are presented. Based on experimental research and calculations, empirical formulas were proposed to calculate the combustion heat of composite fuel, containing a mixture of sunflower husk, sludge, irrigation, chicken droppings and manure. The dependence of the heat of combustion of composite fuel, produced from the waste of the biomass from agricultural production on humidity has been researched. Since briquetted fuel from such wastes has a significant hygroscopicity, it is recommended to provide appropriate conditions for its storage. It is concluded that during the long-term storage of poultry and livestock waste there may be biochemical processes that change the heat of combustion, indicating the need to take into account the terms and conditions of storage of the source components. It is concluded that composite fuel from biomass waste from agricultural production can be a significant component of the country’s fuel balance, saving traditional fossil fuel. In addition, the disposal of these wastes contributes to the reduction of environmental pollution.
On the ground of the conducted research, based on the stated goals and objectives, the model of calculating the operating profit of industrial enterprises, which is based on economic and mathematical dependencies, and takes into account the problem of optimal distribution of production resources in the system of operational management has been improved. Great attention has been paid to the analysis of the cost factors in the system of analysis of the ratio of “costs – volume – profit”, the definition of the optimal distribution of productive resources from the set of possible (admissible) ones in the organization of labor and production, the difference between accounting and economic approaches to calculating profit, the difference in approaches to the classification of overhead costs in terms of activity-based costing.
The purpose of the article is to develop a methodology for assessing the effectiveness of household savings mobilization policy. The object of the study is the mechanism for implementing macroeconomic savings policy in Ukraine for the period of 2005-2017. The subject of the study is the measurement of the cumulative effect of certain means of state regulation on the dynamics of population savings. The overview of literary sources has shown that the problem of household savings mobilization is considered by scientists in the context of investment resource formation and as an important aspect of anti-crisis regulation and ensuring economic growth. The analysis of statistical data of Ukraine revealed a significant volatility of the share of household savings in the structure of gross savings of all institutional sectors of the economy. This dynamics, on the one hand, reinforces the thesis about considerable resource potential of household savings in the formation of investment funds, especially during periods of financial crises, and on the other hand, demonstrates the problem of ineffectiveness of the state policy of mobilizing savings in Ukraine. In this connection, there is a need for a quantitative assessment of the effectiveness of the macroeconomic policy of mobilizing savings at the national level. The authors propose a methodology for calculating the macroeconomic savings efficiency index based on a set of selected factors. The sequence of calculations includes the following stages: stage 1 – measurement of the tightness of connection between the dynamics of household savings and individual macroeconomic variables to identify the most effective factors of influence; stage 2 - normalization of the indicators and their further use in constructing a correlation-regression model for the quantitative measurement of the power of influence of certain factors on the result; stage 3 - calculation of the efficiency index of individual policy of the mobilization of savings. It has been found out that the state policy of household savings mobilization in Ukraine had a wave-like effect, conditioned in the first turn, by the inconsistency of the use of various tools and instruments of influence.
This work showcased the chemoinformatic study of isoxazoline ectoparasiticides: Fluralaner (FLU) and Afoxolaner (AFO) interactions with l-glutamate-gated chloride channels (3RHW). In order to evaluate inhibition thermodynamics, computational approaches such as molecular docking were employed. Results evidenced that FLU-3RHW highest scoring pose presented lower Gibbs free energy and henceforth, lower Ki values than AFO-3RHW. The findings herein reported suggest therefore that computational methods might be useful to study the thermodynamic features of ectoparasiticides used in veterinary care, what might shed further light on their chemical and pharmacological properties.
