Molybdenum is not a well-known microelement, but being a constituent of several important cellular enzymes it is an essential microelement. Molybdenum occurs in all foods, but at very low levels. There does not appear to be any particular foods or types of foods, which in the absence of extrinsic factors, naturally have high levels of molybdenum. However, environmental pollution, from natural or anthropogenic sources, can lead to high level of the metal in plants.Our study is based on the long-term field experiments of Nagyhörcsök, where different levels of soil contamination conditions are simulated. Soil and plant samples were collected from the experiment station to study the behaviour of molybdenum: total concentration, available  concentration, leaching, transformation, uptake by and transport within the plants, accumulation in different organs, phytotoxicity and effects on the quantity and quality of the crop. In this work we present the results of maize and peas and the soil samples related to them.According to our data molybdenum is leaching from the topsoil at a medium rate and it appears in the deeper layers. In the case of plant samples we found that molybdenum level in the straw is many times higher than that is in the grain, so molybdenum accumulates in the vegetative organs of the plant. The data also show differences in the molybdenum-uptake of cereals and Fabaceae (or Leguminosae).

Abstract Background Increasing numbers of patients surviving malignant bone tumors around the knee joint have led to an increasing importance to investigate long-term results. This study assessed the long-term results of rotationplasty after resection of malignant bone tumors regarding functional outcome and quality of life to allow better comparison with other treatment options in bone cancer treatment. Procedure 60 participants who underwent rotationplasty due to bone cancer took part in this multicentric questionnaire-based study. The long-term functional outcome was measured by the Musculoskeletal tumor society score (MSTS) and the Tegner activity level scale. The health-related quality of life (HRQL) was assessed by using the Short Form Health Survey (SF-36). Results Patients treated with rotationplasty (median follow-up of 22 years, range 10–47 years) regained a high level of activity (median MSTS score of 24). Even a return to high level sports was possible (mean Tegner activity level scale of 4). Duration of follow-up did not influence the functional outcome. HRQL scores were comparable to the general German population. Concerns of psychological problems due to the unusual appearance of the rotated foot have not been confirmed. Conclusion Rotationplasty can be a good alternative to endoprosthetic replacement or amputation, either as primary surgery or as a salvage procedure. Especially for growing children and very active patients rotationplasty should be considered.

The paper considers contemporary approaches of long-term forecasting of world and national economics. Foreign practice is of especial interest of authors. Researches and results of PricewaterhouseCoopers and Goldman Sachs are exposed in details. Authors make the following conclusions: a production function model is used often to generate forecasts. The parameters of these models are postulated by experts in coincidence with their scenario of World development. Main indicators to forecast are GDP, GDP per capita and changes in country ranks. Authors consider GDP as not ideal indicator for the goal since it may be calculated by three methods. Besides, it has different structure and quality in different countries. Authors point to the need for estimation and comparison of quality of life. They suggest to take into account the revolutionary changing in technologies and to schedule the optimum and the most realistic path to improve the quality of life. Authors suggest that the most developed countries are entering a new era when robots will work more and more instead of people in industry, agriculture, and services. Many operations in control, management and data processing gain higher productivity due to endless progress in computer science. As a result authors foresee further shortening of the working week. On their opinion this is the way which leads to real success in struggle against unemployment. ICT technologies enable many employees to work now at home. Growing of spare time leads to new pattern of life, new possibilities of education, new types of creative work, new possibilities of communication, additional possibilities for health care, high level of life quality. So far, comparison of national economy development on the basis of measuring GDP seems to become obsolete and irrelevant to current social and economic conditions. Now we can expect to see negative rates of GDP growth and augmentation of life quality. Thus, to construct the countries’ ranks in world competition correctly it is of great importance to take into account the social factors and the role of innovation technologies in world economic development.

Competitive Behaviour

AbstractData from several field experiments support the existence of a trade-off between number and quality of offspring. However, long term effects of brood size on fitness related traits of offspring have been a relatively neglected area of research. In a laboratory experiment the effect of manipulated brood size on subsequent competitive ability of adult offspring was investigated. Zebra finches, Taeniopygia guttata, were reared in small or large broods and young were exchanged in such a way that natural siblings from different rearing conditions could be compared. Competitive behaviour was assessed in two different contexts: competition for food (both sexes tested) and competition for mates (only males tested). There was no significant difference between males from small and large broods in number of succesfull attacks (after which the other male moved away) during male-male aggressive interactions provoked by the presentation of a female in an adjacent cage. Nor did brood size affect latency to eat, time spent eating or success at displacing the other bird from the feeder during food competition tests. The results thus suggest consistently that later competitive ability of offspring is not affected by brood size in this species.

Long Term Evolution (LTE) is the 4th generation of cellular telecommunications technology. According to the standard, LTE provides uplink speeds of up to 50 Mbps and downlink speeds of up to 100 Mbps. In the Denpasar area is a region that has a high level of data package usage, especially LTE technology, which is an average of 83,790,262 Gbits per day, because this area is an area with a fairly dense population. The method that is currently widely used to determine the quality of a network is the Test Drive method. In this study, the author will take a sample of RSRP values for distances of 100 - 400 m in BTS L_Bundaranrenon_PL, BTS L_Akaba_PL and BTS L_Myamin_CR owned by PT. Indosat. In the results of the study, by comparing the RSRP value of the simulation results using the Atoll Software with the RSRP value from the Test Drive obtained a correction factor value, which will then be added to the simulation to get a RSRP value closer to the simulation using the Atoll Software with the Test Drive results. Correction factor value obtained after adding attenuation to the simulation for housing conditions the maximum margin value is -4.99 dBm, while for the open area condition the maximum margin value is -4.22 dBm.

Advances in the treatment of brain tumors have led to an increase in the number of survivors of this disease. Consequently, the long-term complications associated with past and current treatments are becoming more apparent. Of relevance to patients who receive treatment of brain tumors are the potential neuroendocrine complications that develop either acutely or several years following treatment. Presentation may differ between adults and children (e.g., short stature or adult growth hormone deficiency) but in both settings can complicate treatment and impact quality of life. The risk for the development of these complications depends on the location of the tumor (proximity to the pituitary/hypothalamus) and/or the treatment delivered (chemotherapy/surgery/radiation). Given the potential overlap in symptoms attributable to the underlying brain tumor and neuroendocrine dysfunction, a high level of suspicion, appropriate investigation, and administration of treatment may reduce morbidity and mortality for patients with brain tumors experiencing neuroendocrine dysfunction.
