This paper starts from a comparison between the manners in which soils polluted with oil products are protected by two types of legislations, yet for a common environment, namely the superior basin of the Tisza River. Within this article we compare elements from the current legislation regarding the protection of the soil in Ukraine and in Romania (EU member state).\nThe authors seek to answer the following question: is it more useful to have a legal system which regulates very strictly and generally the limits of the occurrence of oil pollutants in the soil, or one that adapts to the structure of the soil as “a living organism”, with specific rhythms, yet ever more affected by the various economic activities?\nSystems for the classification of soils polluted with oil products have been elaborated for both states, and highly efficient methods for the depollution of the soil, subsoil and polluted aquifers have been developed. Yet the long-term practical activity proves that we need to understand the processes and phenomena of soil pollution as a whole – impregnation, accumulation, transfer, cushioning, natural attenuation, the inevitability of environmental accidents etc., while the current level of technical and scientific knowledge requires new methods of approach.
Occupational accidents pose serious problems in both Turkey and the World. The human factor seems to be the most common reason for these accidents. While preventive measures can be taken against occupational accidents, there are some humanistic obstacles, such as fatalistic beliefs, that impede these measures. The literature on organizational behavior supports that fatalistic belief has many personal and organizational consequences. The main purpose of this study is to test the effect of fatalistic beliefs regarding occupational accidents on job satisfaction and organizational trust. It was hypothesized that fatalistic beliefs in regards to occupational accidents have a negative effect on job satisfaction and organizational trust of employees. The study was carried out in five and four star accommodation companies in Alanya, Turkey. A quantitative research approach was adopted. Fully structered questionnaires were used as the measurement insturement. One thousand five hundred and sixty four questionnaires were analyzed. The Structural Equation Modeling analysis indicated that fatalistic beliefs regarding occupational accidents have a strong negative effect on both job satisfaction and organizational trust of employees in accommodation companies, therefore the hypotheses were strongly supported. These results indicate that attempting to overcome fatalistic beliefs and investing in occupational health and safety is a good business decision, as well as an ethical one.
In this work, a second-order Crank-Nicolson type scheme in both space and time, a fourth-order compact scheme in space and sixth-order compact scheme in space are proposed for the derivative nonlinear Schrödinger equation. The Crank-Nicolson type scheme is tested to satisfy the conservation of discrete mass. For the two compact schemes, the iterative algorithm and the block Thomas algorithm are adopted to enhance the computational efficiency. Numerical experiment is given to test the mass conservation for the Crank-Nicolson type scheme as well as test the accuracy order of the three schemes. In addition, the numerical simulation of binary collision and the influence on the solitary solution by adding a small random perturbation to the initial condition are also discussed.
This paper presents represent tracking of maximum power point MPP from PV panel using Perturb & Observe (P&O) algorithm. The MPP technique P&O track the incident light fall on the PV panel according to that control the DC-DC boost converter to provide maximum power to load. The I-V & P-V graph of the PV panel depends upon the incident light and is non-linear in nature. Hence for the different incident light intensity the maximum power point is different or for a certain climate condition there is only one maximum current and voltage to generate maximum power. The model of PV solar system is modeled in MATLAB/SOMULINK which contain solar panel modeling, DC-DC converter model, P&P MPPT algorithm. The simulation is done under different incident condition of sun light from 200-1000 kW/m2 at different temperature range from 100 to 500 centigrade.
Background We compared the clinical outcomes of coronary artery bypass grafting (CABG) in patients with acute coronary syndrome (ACS) versus those with stable angina pectoris (SAP).\nMethods From September 2009 to September 2014, 185 patients with SAP and 84 patients with ACS (unstable angina pectoris and ST-segment elevation with myocardial infarction seen on electrocardiography) underwent first-time isolated CABG at our institute. Clinical outcomes were compared between the two groups.\nResults Although ACS was an independent predictor of early mortality in patients undergoing CABG, the long-term outcomes after surgery were similar between the two patient groups who survived the late postoperative period.\nConclusions ACS was an independent predictor of early mortality in these patients undergoing CABG, which provides revascularization of most of the epicardial vessels, including the culprit lesion. Therefore, it might reduce the likelihood of future ischemic events in patients with this syndrome.
The article demonstrates the influence of virtual reality on the micro-alterations in a personality. The authors study the effect of the specially designed VR training programs upon a number of personal traits and alteration in subconscious attitudes towards phobic situations. In fact, the technologies designed in the virtual reality do not affect the basic personal structures, rather they only influence the functional personal characteristics. The research is devoted to the application of the VR products which are aimed at the achievement of the progressive personal changes and applied for a short period if time. The experiments results show that if a user prone to phobias identifies him or herself with an avatar in the virtual reality, it results in his or her more positive attitude towards the components of the phobic situation.\nKey words: personal changes, phobias, attitudes, training programs in virtual reality.

One of the main areas in developing the economy of any country is the planning of the foreign direct investment (FDI) to be employed in a proper manner as a very crucial tool in development. FDI has many effects; and one of them is flourishing the ICT sector as a vital sector which includes four sub-sectors according to the World Bank (High-Technology Exports, ICT Goods Exports, ICT Goods Imports, and ICT Service Exports).\nHence, the paper aims to identify the effect of FDI on flourishing ICT sub-sectors as one of the drivers of economy development. To achieve this purpose the statistical data published by the world bank about Oman on direct foreign investment and Omani IT exports and imports were collected from 2000-2014. To analyze the collected data and test the hypotheses of the study, descriptive statistics and Simple regression model were used.\nThe results show that there is ad-hoc planning of FDI and there should be a clearer view of how to exploit FDI in economy development and especially in ICT transferring. This study contributes to the literature by being the first study that demonstrated the role of FDI on IT exports and imports in Oman.
In this study, we have investigated the second socialization place, in particular, the high school type, where we worked with four A-level schools (Gymansium). At first, we looked into the grades of the female and male students, where both have shown high scores in different courses. Then, a survey which was conducted on the students, has shown, that they have prejudice to courses and to jobs related to their gender. But we couldn’t see this type of opinions in students, whose parents have high level of education. The study showed that the first socialization place, namely the family and family education, have more dominant role in a child’s life, than the second socialization place.
An objective assessment of sound parameters was needed for patients unilateral vocal fold paralysis (UVFP). The acoustic parameters, which were analyzed before autologous fat injection laryngoplasty, were compared the differences in acoustic analysis. Thirteen patients with UVFP were recruited and received acoustic assessment before injection laryngoplasty. After 1-month, 2-month, and 6-month follow-ups, failure and success groups were compared via diagnostic evaluations. High frequency, low frequency and soft phonation index of acoustic parameters could be used to compare the changes on failed and success autologous fat injection laryngoplasty at least 6 months. The frequency perturbations parameters may be used to prognosticate the success rate before the injection laryngoplasty.
Purpose: To assess the vision, retinal thickness and morphology of the subjects after higher gravitational stress. \nMethods: A total of 40 male military aviators (80 eyes) with mean age of 25.5 ± 0.8 years were enrolled in March 2015. Nine folds of gravitational forces were created by human centrifugation. Vision was evaluated by a log MAR chart and retinal thickness was measured via optic coherence tomography. Moreover, retinal morphology was recorded using a non-mydriatics ophthalmoscope. The difference between these parameters before and after centrifugation (just immediate, 15 min and 30 min) was compared. \nResults: The mean vision slightly dropped (0.05± 0.05 vs 0.19 ± 0.05 log MAR; P<0.05) just immediately after centrifugation, and then returned to normal. The increased retinal thickness was found within 30 minutes; however, the changes were all not significantly apparent (P>0.05). Furthermore, the increased level of retinal thickness did not affect humans in clinics. Moreover, 15 % of the subjects showed various degrees of dot hemorrhage in peripheral retina and disappeared within 5 days. \nConclusion: Changes in the posterior segment of eye were never reported after higher gravitational stress. We suggested that hemodynamics other than retinal thickness and superficial hemorrhage may affect the vision of military aircrew during accelerating flight. \n \nKey words: retinal thickness, gravitational stress, optic coherence tomography
A polyphasic approach consisting of morphological, chemical and molecular characterization was applied to 22 isolates of different species of Fusarium. Yeast selective culture, immune affinity column and molecular characterization were conducted to identify the toxigenic Fusarium isolates. Randomly representative sample of wheat grains were collected from different area of Saudi Arabia. These samples were used in Fusarium isolation trials. Two strains of yeast; Saccharomyces cerevisiae and Kluyveromyces marxianus were tested to differentiation between toxigenic and non-toxigenic Fusarium isolates which had ability to excrete Zearalenone (ZEA). Immuno-affinity column and ELISA used to determine the ZEA as well as HPLC. The presences of the toxigenic genes is correlate with toxicity therefor polymerase chain reaction (PCR) was performed using one set of primers specifically targeted to gene of ZEA biosynthesis pathway with all tested species of Fusarium. The most of Fusarium were namely; Fusarium graminearum, F. verticilliodes, F. oxysporium, F. culmorum, F. avenaceum, F. redolen, F. solani F. udum, F. semitectum F. chlamydosporum, F. proliferatum and F. poae. \nMost of the Fusarium species reacted positively with tri5-gene-specific PCR primers that cover the region from 460 to 1340 of tri5 regulatory gene with product size of 798 base pairs (bp). Using the primer pairs Tox5-1/Tox5-2, a single fragment of about 500 bp was amplified only when genomic DNA from the Fusarium isolates was used. DNA template for Fusarium reacted with primer provided 1232 bp PCR product. No amplification was observed with DNA from other species or fungal genera. \nDetection and quantification will provide importance information to predict toxigenic profiles which may be present in these row materials of feeds. The objective of the current study found the accurate, cheap and realistic estimation of ZEA toxin contamination to appropriate strategy to detoxify and/or decontaminate this toxin.
