Relative performance of students by gender in public examinations was assessed using questionnaires and standardized test on one hundred and eighty students from some selected urban centered schools in Benue State. Casual comparative design and correlation design were used and the results showed that socio-economic status of parents affects the performance of their children/wards (students), and there is no significance difference in the level of performance between boys and girls in public examinations. Parent should be enlightened through seminars and workshops on the importance of educating themselves and their children/ward. Governments, nongovernmental organization (NGO’S) and individuals should establish more schools for more education of both sexes. These were the suggestions advanced.
The contribution is aimed on the analysis of company’s profitability especially on rate of return on assets – ROA indicator. The article is divided into two parts. In the first part is characterized indicator ROA and the ROA is disaggregating into two components: profit margin and total assets turnover. In the next part are analyzed the main factors that impact ROA and determine the level of the ROA. The main factors can be classified as operating leverage, cyclicality of sales and product life cycle.
Requirements for flexible manufacturing have been increasing in the last years. In order to insure effective operation of expansive manufacturing equipment, which has to run automatically and unattended, tool monitoring is important. Therefore, the essential problem to be overcome to achieve the full potential of unmanned machining is the development of effective and reliably sensors systems to monitoring the process and corrective action in case abnormal operation. The ultimate goal of the development of such production equipment is to enhance the overall economic of the manufacturing process. Even when there are at present many monitoring systems commercially available in the market for tuming processes, serious difficulties still remain to be solved to apply monitoring systems successfully in machining centers. Being these difficulties mainly related with the limited accessibility to the rotating tool for sensing purposes in tool driven machining processes. Therefore, the primary objective of this paper assess the feasibility of using force signal analysis as means for monitoring tool condition in drilling.
Production quantity, quality, and prices of cow milk in Czech Republic, as well as in Poland, are permanently influenced by economic factors and, after EU participation, also by the milk quota regime. Alongside similarities production characteristics, in Poland and the Czech Republic there exist substantial differences. The aim of this study was to overview changes taking place in the meat and milk sectors of the Czech Republic. Despite the decreasing cattle population (including dairy cows), production in the Czech Republic is rather stable because of rising milk yield. During the last few years there has been a milk surplus on the market, even thought dairy exports dominate over import. A precondition of the realization of milk on the market is its high quality and this has become a basic prerequisite for profit and for the maintenance of the customer in the competitive market. An analysis has therefore been carried out of the economic indicators of the dynamics of milk yield, overall production and the quality indicators of milk, the bulk purchase and buying price of milk, during the years 1998 to 2004, including a survey of the costs, profits and the marketability of milk in the given years. In 2004, the milk purchase price, including compensation payment, ranged around 8 crowns (CZK) per litre. However, the production costs of milk sold increased to 8.42 crowns resulting in a lack of profitability. This was a result of an increasing growth rate in expenditure over milk yield. The level of expenditure and profits of the milk production of agricultural enterprises is going to be comparable with average results attained in EU-15. The static level of milk production is characteristic for all countries operating with a milk quota regime (EU-15, Norway, Switzerland and Canada). Individual reference quantities become a limiting factor for many producers. Based on EU data milk output is forecast to exceed national quota for 2005/6 in Czech and Poland, exposing both countries to hefty fines.
The nations need more and more energy to achieve their main objectives, launching the economic growth, or at least maintaining it. There is a relationship characterized by an inverted U-shaped curve between the emissions of pollutants (some local contaminants, such as nitrogen oxides, sulfur dioxide, heavy metals) per capita and GDP per capita distribution. We selected nine observation variables and twenty-seven observation units. Each observation units are OECD member states. It is expected to be confirmed that between the values of the energy consumption and greenhouse gas emissions and gross domestic product growth there is a statistically significant relationship. The so called developed countries need more and more energy to produce their GDP (for example agricultural production) and because of this their CO2 emission increased in the observed period of time. The strongest relationship of the whole analysis is between the observation units, energy consumption and CO2 emission. Unfortunately we can state that if a country wants to raise its GDP-level this country will use more energy to achieve this goal. The source of the large part of extra energy will be fossil fuels because they are still the cheapest energy sources.
A deterioration of shelf life may be pertained to a lack of appropriate sensory attributes, or the appearance of a health hazard. Meat products are primarily exposed to the action of microorganisms. The rate of changes during storage, which may lead to microbial contamination of products, and changes in their sensory attributes are affected by the properties and microbial contamination levels of raw materials, the nature and conditions of the technological process, the character of the product and the amount and type of additives. However, in case of the tested wiener type sausages, the quality of which was modified by colouring with cured blood or a betanin solution and which were aromatized using a mixture of spices (lovage root, dried garlic, 1.5:1.0:4.0) no accelerated storage changes were observed in comparison to the reference sausage. The applied modifications of the technological process do not mask storage changes in the analysed sausages. A distinct deterioration of sensory quality characteristics preceded by 3 days the alarm level of microbial contamination of sausages (an increase in the total aerobic bacteria counts to the level above 1 x 106).
