TREATMENT OF GROUND WATER CONTAMINATED OIL DERIVATIVES

Treatment of groundwater is the most important part of the scope of protection of natural resources, because no biological and bacteriological water there is no life on the planet. Implemented through consideration of all the negative elements in the water, determine the percentage of their toxicity and finding the most appropriate method for their removal. The aim is to monitor, improve water quality and the environment in general observed

Stočarska farma kao podsistem poljoprivrednog gazdinstva

In this paper we have overviewed expert views of experts considering cattle breeding influence on farming. Managing director of the farm has a lot of possibilities for suitable technological, technical, organizational economical and ecological solutions and its use for optimizing business results. Positive influence on business results might be achieved using rational managing factors as: specialization- diversion, intensity-extensity size of farm, race choosing and suitable zoo-technical means, harmonizing farm function with ecological demands, successful adaptation toward natural and economical conditions etc. Most of these factors have one common thing avoiding extreme solutions influences business results. Balance in farm functioning and in its development are marks showing basis of successful management.Analizom rezultata većeg broja naučnoistraživačkih radova razmatrana je uloga stočarstva u promeni konkurentnosti poljoprivrednog gazdinstva.

the variability in P300 cognitive evoked potential amplitude in the auditory oddball paradigm

One of the best-studied responses of cognitive evoked potentials is a so-called 'P300', the late positive wave complex that occurs about 300-500 ms after the stimulus. It is obtained when the subject's attention is focused on a signal that is rare, especially if the signal has a motivational or emotional meaning. In the study of P300 potential, we followed the variations of potential amplitude and latency, so the objective was to examine whether there is a difference in Fz and Cz amplitudes of auditory induced cognitive evoked P300 potential depending on the performance of oddball tasks, both in male and female subjects. The study included 60 subjects (30 female respondents and 30 male respondents). P300 potential is induced by the auditory 'oddball' paradigm with 80% of non-target and 20% of target stimuli that are presented to the patient through headphones. The target tones are high tones of 2000 Hz. The standard, 1000 Hz tones the respondent should ignore but when he hears the target tones the respondent should press the button on the special handle. The value of Fz and Cz amplitudes both in male and female subjects obtained in the classical 'oddball' paradigm when the subject reacted to the signal by pressing the key with the dominant (right) arm were statistically significantly lower (p>0,05) than the values of Fz and Cz amplitudes obtained when the key was pressed by the non-dominant hand. Based on this experiment it can be concluded that both in male and female subjects the performance of oddball tasks does not affect the amplitude of P300 cognitive evoked potentials

Poor life habits: Risk factors for formation osteoporosis

The use of bone density measurements is of central importance for diagnosis, prognosis end the assessment of treatment of patients with osteoorosis. Risk factors are variables which significantly change expected absolute risk, that is, the probability of variable disease in a certain population. Aging and smoking are the most common listed risk factors for the development of osteoporosis. The aim of our work was to confirm the most common risk factors for osteoporosis. In our research work has processed a total of 88 smokers were divided into groups according to the number of cigarettes smoked and the length of smokers. Results showed that risk factors: poor life habits (smoking and use of coffee), are significantly represented on patients with osteoporosis. In order to timely implement treatment, we concluded based on the results, that there is a need actively look for presence of risk factors responsible for osteoporosis in our patients
