EVOLUTION OF SUPPLY AND DEMAND OF WHEAT IN ROMANIA

EVOLUTION OF SUPPLY AND DEMAND OF WHEAT IN ROMANIA

Wheat is unique. Of all the seeds in the plant kingdom, the wheat grain alone has the gluten proteins capable of forming the fully elastic dough required to bake leavened bread. These gluten proteins are also needed to make the great variety of foods that are associated with wheat around the world [1]. This unique property is the reason why over 2 million hectares of wheat plants are cultivated in Romania, producing well over 7 million tonnes of grain. This level of wheat production is equivalent to an average of nearly 165 kg of grain per person per year. However, in practice, this theoretical estimate is meaningless, since the regions of wheat production differ from the populations in need of the grain. Furthermore, wheat is one of the most important food plants cultivated in many countries, feeding 35-40% of the world population and is an important source of trade [2]. The main use is for the manufacture of bread and various products that are made from flour, and stems (straw) remaining after harvesting have multiple uses: raw material for manufacturing of pulp, bedding, feed, organic fertilizer, incorporated into the soil

The Financing of Water Supply and Sewerage Services in Romania

The Financing of Water Supply and Sewerage Services in Romania

Beyond the initial establishment, any intervention in the pricing and tariffs of public utilities, like their adjustment and modification, is made according to the calculation methodologies developed by the regulatory authorities. The adjustment is the procedure of increasing prices and tariffs which is encountered when real influences received after costs caused by the evolution of prices and tariffs in the economy, based on an economic and financial analysis of the economic operator, are found to be necessary in order to change their structure to cover the costs of exploitation and operation of water supply and sewerage systems, through which these services are provided to users. The new levels of prices or tariffs resulting from the adjustment are subject to approval of ANRSC then approved by the deliberative bodies of territorial administrative units. The adjustment of prices and tariffs is permitted by law, under the previously stated conditions, at a month-interval. The expert opinion of the regulatory authority shall include, in case of adjustment, the quantum of the price or tariff for public water supply and sewerage services, and also the value of the price or tariff at the date of the adjustment, because according to these data the next subsequent adjustment parameter will be determined. The prices and tariffs for public water supply and sewerage services are set by the operators or the economic operators.

Pig slurry as a nutrient source in wheatcorn succession

Pig slurry as a nutrient source in wheatcorn succession

Wheat and corn are important grains in the agricultural scenario of Brazil, and demand adequate supply of nutrients, particularly nitrogen, in crop succession. The use of pig slurry (PS) as a full and/or partial alternative to mineral fertilization in crop areas has been identified as an important alternative for the disposal of this waste. Therefore, the objective of this study was to evaluate the utilization of PS as fertilizer in wheat/corn succession under some plant parameters and grain yield. The experiment was conducted under field in randomized block design with four replications and five treatments, three with PS (40, 80, 160 m³ ha -1 ) and two controls (no fertilization and mineral NPK fertilization),

SUSTAINABLE TOURISM DEVELOPMENT - IMPORTANT COMPONENT OF SPATIAL TOURISTIC PLANNING

SUSTAINABLE TOURISM DEVELOPMENT - IMPORTANT COMPONENT OF SPATIAL TOURISTIC PLANNING

Through its specificity, the tourism industry is directly related to the environment, more than other industries. Running uncontrolled tourism activities, at random, without taking into account the development and exploitation standards can lead to the environmental degradation and tourism resources. To achieve the travel activities the best possible is required, besides the natural, human and material resources, to satisfy the tourists' needs. Material and technical endowment of tourism is represented by: accommodation and food services, transportation, treatment and leisure facilities and is primarily conditioned by developing and modernizing the existing endowment. Thus, a highly attractive tourist area could not be on offer before having the facilities for receiving and retaining potential tourists. In order to decide on the tourism development of an area, it is needed an analysis of the tourist traffic to the existing tourist settlements. This paper achieved a study case on the tourism demand and supply in Bucharest, the capital of Romania. For this purpose, a series of tourism indicators regarding the tourism demand and supply have been calculated, analyzed and interpreted.

Investigating The Use Of Mobile Computing In Zimbabwe Polytechnics Case Of A Polytechnic In Zimbabwe

). This shows that there has been upgrading and improvement in mobile computing device characteristics since Zimm erman’s research up to now. Dahlstrom (2012), a senior research analyst at EDUCAUSE, in his article titled ―Executive Summary: Student Mobile Computing Practices—lessons learned from Qatar‖ says that students find Mobile technology convenient and engaging and institutions need to invest more in mobile device use and support. In Qatar the Education City conducted a survey jointly with ECAR (Every Child a Reader) of United Kingdom (UK) on student mobile computing technology and the results were not only relevant to their student’s experiences but also speaks to the global revolution of mobile technology in the academic environment. The findings revealed that, for students, technology plays an important role in productivity and communication, students want technology integrated into their academic experience and students want to better utilise mobile technology in their learning environments doing such things as creating content for course assignments, accessing course related material and pushing the limits of mobile device productivity. Kim et al (2006) identified the benefits of using mobile wireless phones as freedom of location and time, increasing speed in teaching and learning, enabling one-to-one learning based on individual educational histories or test results, better communication opportunities and better collaboration in group discussions. They also identified the specific benefits of using Personal Data Assistants in m-learning as mobility, information management capacity, beaming capability, ability to work in many places and replacement of pen and paper. A UK essays website argued that the major challenge for educators and trainers is how to develop learning materials for delivery on

Effect Of Shape And Plan Configuration On Seismic Response Of Structure

Effect Of Shape And Plan Configuration On Seismic Response Of Structure

Abstract: Earthquake is a very important aspect to be considered while designing structures. Lot of work has been reported by many researchers who worked to study the effect of structures with irregular plan and shape. Being inspired from the work contributed in the study on effects of earthquake on irregular shaped building in plan, this paper presents effects of plan and shape configuration on irregular shaped structures. Buildings with irregular geometry respond differently against seismic action. Plan geometry is the parameter which decides its performance against different loading conditions. The effect of irregularity (plan and shape) on structure have been carried out by using structural analysis software STAAD Pro. V8i. There are several factors which affect the behavior of building from which storey drift and lateral displacement play an important role in understanding the behaviour of structure. Results are expressed in form of graphs and bar charts. It has been observed from the research that simple plan and configuration must be adopted at the planning stage to minimize the effect of earthquake.

The modification process of AlSi21CuNi silumin and its effect on change of mechanical properties of the alloy

The modification process of AlSi21CuNi silumin and its effect on change of mechanical properties of the alloy

Essence of modification of silumins boils to change of form or size of silicon crystals present as eutectic or primary ones. Perfect sliding properties and high abrasion resistance of hypereutectoid silumins result from their structure, which can be characterized by precipitations of primary crystals of silicon in soft eutectic groundmass. Primary crystals of silicon are unfavorable due to their impact on machinability of material. They bring about considerable wear of tools and have negative effect on conditions of machined surface (big roughness). In case of hypereutectic silumins, by introduction of active nucleuses of crystallization are refined mainly a brittle, hard precipitations of primary silicon [1]. High content o silicon results in necessity of superheating of the alloy in limits of 850 – 900 C and keeping it

Assessment Of NPK In Human Male And Female Urine For Its Fertilising Potential In Agriculture

Assessment Of NPK In Human Male And Female Urine For Its Fertilising Potential In Agriculture

discharge into water is reduced by about 60% irrespective of the type of treatment [10]. Pure urine is sterile but there is the likelihood of cross-contamination with the use of urine separating (Ecosan) toilets [28]. According to Jönsson et al. (2000) separated urine contains a greater part of the total nutrients in normal sewage; 80% of N, 55% of P, and 60% of K in just 1.5% of the volume of the sewage. According to Rheiberger (1936), there are comparable levels of creatine, urea and ammonia nitrogens in urine among primates such as man, mangabeys, baboons and chimpanzees. However, he identified sex differences in creatinine nitrogen coefficients of the male mangabeys, baboons and chimpanzees to be higher than those in the female counterparts. In small cases there was reversal of the magnitude seen in the macaques species precluding an assumption as to the validity of the observation. In analysing sex differences in urine with respect to lysine and α - amino nitrogen, the mean excretion of α - amino nitrogen whether ―total,‖ ―free,‖ or ―bound,‖ was higher for females than for males [22]. Thus, it is possible that the higher rate of amino acid excretion observed in females might be correlated with the sexual cycle, although no evidence of this was observed in the case of the four amino acids studied by Thompson and Kirby (1949) when samples from the same subjects were taken at various stages of the menstrual cycle. The influence of sex (gender) on the level of NPK in human urine has received no attention. Therefore, there is a need to study the effect from the Ecological Sanitation (ECOSAN) perspective, especially under local conditions. This is because gender ECOSAN urinals are going to spring up with the advent of industries and ECOSAN concepts, especially in the developing countries. The use of urine in agriculture has been studied in countries such as Sweden, Germany, Switzerland, South Africa, Burkina Faso and Nigeria. In all these studies, the fertilizing ability of human urine was established as being comparable to that of chemical fertilizers, such as 21% N ammonia. However, in Ghana little U

Influence of tungsten and titanium on the structure of chromium cast iron

The paper analyses the as-cast state structure of chromium cast iron designed for operation under harsh impact-abrasive conditions. In the process of chromium iron castings manufacture, very strong influence on the structure of this material have the parameters of the technological process. Among others, adding to the Fe-Cr-C alloy the alloying elements like tungsten and titanium leads to the formation of additional carbides in the structure of this cast iron, which may favourably affect the casting properties, including the resistance to abrasive wear.

An Analysis of Student Evaluations of Native and Non Native Korean Foreign Language Teachers

An Analysis of Student Evaluations of Native and Non Native Korean Foreign Language Teachers

The most common type of complaint from students was un- questionably related to excessive lecturing on the part of the native TA (about 70% of negative comments related to excessive lecturing, not enough time to talk.) Students often felt shorthanded when not given opportunities to discuss topics in class. (Although this contra- dicts the statements above related to difficult discussion topics, we should assume that students who requested more discussion in class are expecting discussion at an appropriate language level.) One stu- dent said of a native male TA, “I think if there were more opportuni- ties to speak instead of hearing him speak for most of the class, it would have been more beneficial.” Another complained about a na- tive female TA, “She was very enthusiastic about teaching, but activi- ties that actually involved speaking were sparse.” More than anything else, students mentioned discussion in the classroom, and the majori- ty of these complaints and requests were aimed towards native female TAs: “I did not like how little we got to speak as a class. My under- standing increased but I feel my speaking skills went down”; “More class participation would have been good”; “I wish we would have had more opportunities to have class debates and class discussions”; “mostly a lecture [with] little interaction”; “I think the only thing that could be improved is if she would have us speak more in class.” Fi- nally, one student wrote an extensive comment for a female TA that depicted her as an outstanding TA, but then ended with the sugges- tion that “more emphasis on free class discussion might help.”

Performance Of Different Tillage Implements And Their Effects On Sorghum And Maize Grown In Gezira Vertisols Sudan

Performance Of Different Tillage Implements And Their Effects On Sorghum And Maize Grown In Gezira Vertisols Sudan

Low crop productivity is one of the major problems that are facing agricultural production in the Sudan. Low crop productivity in addition to high production costs, low prices and high taxes had all resulted in a general deterioration of the agricultural sector. This has contributed in converting agriculture from an attractive business to a repellent activity and caused many farmers to abandon agriculture and migrate to cities. The agricultural sector in the Sudan contributes to about 48% of the Gross Domestic Production (GDP) and to about 93% of the foreign currency earnings (Ministry of Finance and National Economy, 1996). It also employs about 65% of the labor force. Sorghum (Sorghum bicolor L.) is the major staple food crop in the Sudan. It is estimated that the annual consumption amounts to about 3.9 Million tons (Elsayed, 1999). It is cultivated in large areas that include both irrigated and rainfed. Farah, et al. (1997) reported that the area which is annually cultivated by sorghum is about 2.1 million ha, of which 80% is completely rain-fed, whereas the remainder is given supplementary irrigation throughout the growing season. The Gezira scheme contributes by 60% to the total irrigated production (Elsayed, 1999). Irrigated sorghum production is characterized by the use of disc harrows and ridgers for land preparation, improved varieties and fertilizers. However, yield per unit area in this sector is still very low 1400 kg ha -1 (Ibrahim, 1992). Great efforts had been put in the Gezira scheme to increase sorghum productivity which led to increase the average yield during the pervious seasons, this could be due to the high adoption rate of the recommended technical packages released by the Agricultural Research Corporation (ARC). Maize (Zea mays L.) is traditionally cultivated along the banks of the River Nile in the northern states and it is also cultivated in southern states. The area cultivated by maize in the Sudan during the period 1989- 1995 is estimated to be about 21,840 hectares (FAO, 1995). However, maize is classified today as a new promising crop in the irrigated projects of central and eastern Sudan. The average yield per unit area of sorghum and maize of the Sudan are very low compared to other areas in the world have the same weather conditions. Vertisols of the Gezira scheme

Evaluation And Characterization Of Trace Metals Contamination In The Surface Sediment Using Pollution Load Index PLI And Geo-Accumulation Index Igeo Of Ona River Western Nigeria

The existence of trace metals in aquatic environments has led to serious concerns about their influence on plant and animal life [2]. Geo-accumulation index is the quantitative measure of the degree of pollution in aquatic sediment. It consists of seven grades ranging from unpolluted to very extremely polluted and the Pollution load index is a quick tool in order to compare the pollution status of different places, the pollution load index is use to determine the pollution severity and its variation along the different sample stations [3]. Heavy metals are chemical elements having atomic weights between 63.546 and 200.590 and a specific gravity that is 5 times greater than that of water. They exist in water in colloidal, particulate and dissolved phases with their occurrence in water bodies being either of natural origin (e.g. eroded minerals within sediments, leaching of ore deposits and volcanism extruded products) or of anthropogenic origin(that is; solid waste disposal, industrial or domestic effluents, harbour channel dredging) [4]. Furthermore, trace toxic metals are not easily removed from the environment nor are readily detoxified or degraded by metabolic activities in the body of the organism, thereby resulting in accumulation [5, 6]. Research has been that, they are no studies on sedimentology and geochemistry of the sediment in Ona River. To provide baseline information and also enlightened the people of the area about the immediate effect of the water body studied, they is need to determine trace metals pollution in sediment using pollution load index and Geo-accumulation Index.

where is a set of linear restrictions that transforms the unrestricted model (1) on restricted model (2). 8 In our case, the restriction implies that the age, trend and (orthogonal) time dummies are sufficient to explain the behavior of each estimated statistic order across cells and over time. Imposing the restrictions means estimating weighted least squares regressions on the grouped data, for each quantile and education group separately. This procedure will give us consistent estimates of . Under the null that the restrictions are valid, the minimized value follows a chi-square distribution with degrees of freedom equal to the number of restrictions. In order to construct the test statistics, we only have to sum up the weighted squared residuals, that is, the estimated percentiles minus the predicted values minus the orthogonal time dummies.
