Oral ulcers are highly common lesions in the population. They are painful and annoying, although most of them would be healed with no significant consequence. It is important to recognize these lesions on time and do the right sorts of treatment because of the risk of cancers or some other critical diseases. Understanding this fact that the first contact for most of patients is usually with a general medical practitioner, we decided to evaluate general practitioners’ knowledge, attitude and behavior regarding oral ulcerative lesions. This study was a cross-sectional, self-administered, questionnaire survey which was done among 65 general practitioners in Isfahan, Iran. The questionnaire evaluated the knowledge, attitude and behavior of general practitioners regarding oral ulcerative lesions. Chi-square test, Pearson's Correlation Coefficient and t-test served for statistical analysis done by SPSS20 software. The physicians’ knowledge score was almost low, especially clinical knowledge (mean score = 33.4%, SD: 15.3). The majority of general practitioners (89.2%) reported that they are more knowledgeable in this field and almost 70% of them showed a willingness to participate in further educational programs about oral lesions. There was a significant relationship between the attitude and age (p= 0.001) and duration of practice (p = 0.002). But there was no significant relationship between the numbers of examined patients. General practitioners’ behavior scores regarding oral lesions were rather low. A significant relationship between the behavior and age (r=0.271, p= 0.03) and duration of practice was observed. Lack of knowledge of General practitioners’ and poor performance about oral lesions besides their willingness to get higher education in this field, revealed a great need for planning to include appropriate additional courses to the curriculum of the medical graduates

This study was carried out to investigate the effects of using treated wastewater on quantitative and qualitative characteristics of Lolium perenne in greenhouse conditions in Sa'dabad of the Dashtestan, Iran. Experiment was performed in a randomized complete block design with 5 treatments and 4 replicates. Treatments included: fresh water, fresh water + 25% treated wastewater, fresh water + 50% treated wastewater, fresh water + 75% treated wastewater, and 100% treated wastewater. Based on the results, it can be concluded that the impact of wastewater had significant effect on growth and physiological characteristics. Root weight (6.7 g), leaf weight (3.6 g), leaf area (8.4 cm2), root length (33 cm) and plant height (11.3 cm) showed a significant increase in compared to the control. In relation to the characteristics of protein, phosphorus and ash, the same trend was observed.

“Youth’s in the rural areas have little option”, this is what they are given to believe and it makes them to work either at farm or migrate to urban land. It is well known fact that best option available to them is rural entrepreneurship. Rural entrepreneurship can be defined as entrepreneurship emerging in rural area or establishing industrial units in the rural areas. This contributes for employment generation, reduces disparities in income between rural and urban income, promote regional development, protect art and creativity and helps to achieve economic development in rural area. Rural entrepreneur is a answer to solve migration, unemployment, promote social and economic inclusion. The strengthening rural area will encourage prevention of natural resources and improve the rural economies. Rural entrepreneurship will have income multiplier effect by creating demand for farm and nonfarm product and services, and by creating job opportunities. Indian economy largely dependent on rural economy as 68.84% of population lives in rural area. There’re about 6,38,558 villages. Due to large number of people lives in rural area, there is wide scope for selling varieties of product. Thanks to growing economy, people in rural area have witnessed increased income, which is positive sign for his product portfolio. This paper also benchmarks the case study of Marate Milk Products Mala, which offers differentiation as a strategy to compete successfully in rural market of coastal district of Karnataka.

Nigerians in my view are a people who live beside the ocean yet, dying of thirst. Our beloved country is blessed with both human and natural resources but her rate of poverty is one that is alarming. In the area of science and technology she is rich abroad but poor at home. Every year, her universities produce graduates who continue to roam the streets in search of white collar jobs. Gradually, the harsh and unpleasant economic situation sows evil seeds in the hearts of these youths thereby, taking to crimes. A people born free now find themselves everywhere in chains. Hopeless as she may seem today, Nigeria is however, not beyond redemption. Critically yes, but not entirely hopeless. To pull her back and turn her around obviously requires a change of ideology. Should we continue to do same thing the same way and expect a different result? How long shall we continue to be slaves in our father’s palace? Mills conception of liberty provides a way out of our national predicament as this essay adopts both analytic and evaluative methods in establishing that liberty would make the people to be creative and innovative, thereby bring about the needed technological breakthrough.

Verbal communication is temporal and easily forgotten, but written reports exist for long periods and yield long-term benefits for the author and others. Individual scientists and groups of researchers perform experiments to test hypotheses about biological phenomena. After experiments are completed and duplicated, researchers attempt to persuade others to accept or reject their hypotheses by presenting the data and their interpretations. The report or the scientific paper is the vehicle of persuasion; when it is published, it is available to other scientists for review. This model of technical report in biology therefore looks into the right way in putting the reports together in a way that is acceptable to other researchers and readers.

The watershed algorithm is a commonly used method of solving the image segmentation problem. Watershed based image segmentation is selected for the implementation, as it exhibits least computational complexity, good segmentation quality and can be implemented in the FPGA. This paper proposes a new parallel watershed based image segmentation technique and its architecture is implemented on Virtex-4 FPGA board. The results show that the proposed architecture requires minimum hardware resources, low execution time and is also suitable for use in real time applications.

A close look at Jean-Paul Sartre’s Humanistic Existentialism reveals an avalanche of implications that clamour for a dismissal of Sartre’s thesis. These implications range from metaphysical implications, to religious, ethical, sociological and other implications. The task of this paper is to critically look at some of these implications and consequences of his Humanistic Existentialism.

Precious metals doped anatase titanium dioxide nanoparticles are used in various applications including environmental photocatalysis and solar cells. In this work we present the synthesis of Au- doped and Pt-doped TiO2 nanoparticles employing sol-gel methodology. The doping procedures based either on UV photodeposition (UV-PD). The morphology, composition, particle size and specific surface area of these synthesized nanoparticles have been characterized using several instrumental techniques namely, Scanning Electron Microscopy (SEM), Energy Dispersive X-Ray Spectroscopy (EDXS), X-Ray Diffraction (XRD), Transmission Electron Microscopy (TEM) and Brunauer–Emmett–Teller (BET) theory. Au impregnated (2%) nano anatase TiO2 powder was examined in photo decolourization of Orange G as dye environmental pollutant under visible light illumination and optimum operational conditions.

Using of tuned mass damper is a common way for reducing responses of structures as a result of wind and earthquake. This damper is consisted of concentrated mass which is connected to the point of structure by a damper and spring. In this paper frame of last floor is used for placing tuned mass damper. For this reason, four models of 4, 8, 12, 20 floor buildings with moment resistance frame are studied under effect of earthquakes of near field Leandros, Northrdig, Kube and Tabas faults. So, mass damper which is suggested on the base of improved values in scientific resources is calculated. On the base of these results, it is possible to found appropriate behavior of tuned mass damper in 12 and 20 buildings.

Given a collection of cities and the cost of travel between each pair of them, the traveling salesman problem, or TSP for short, is to find the cheapest way of visiting all of the cities and returning to your starting point. In the standard version we study, the travel costs are symmetric in the sense that traveling from city X to city Y costs just as much as traveling from Y to X. The Traveling Salesman Problem is typical of a large class of "hard" optimization problems that have intrigued mathematicians and computer scientists for years. Most important, it has applications in science and engineering I attempt to apply simulated annealing to find (Sub-Optimal) solutions to TSP with 100-200 cities randomly. The performance by changing the parameter values and try to understand how fast and effective simulated annealing algorithm can generate a solution to TSP problem.
