Observations of the views of university students on agricultural production

In this study, an attempt was made to examine the perspective of university students and their family members on the agricultural sector, the value they attach to agriculture and their own lands, the level of knowledge and awareness of the agricultural sector where they are engaged in production activities and make a living, and the importance they attribute to the sustainability of agriculture. In addition, the production activities of farmers and their membership in cooperatives or unions were also examined. The surveys conducted by interviewing a total of 200 participants representing university students and their family members within the scope of the research constituted the target material of this study. The obtained survey data were examined and tables containing frequency and percentage parameters were prepared and tried to be interpreted. According to the results of the research, a significant majority of the participants attribute importance to the integrity of the land and believe that agriculture is indispensable. Besides, considering the importance of the agricultural sector and the existing agricultural land, there is a substantial proportion of participants who do not see any harm in non-agricultural use of their lands and state that they will give up their lands in a possible situation

Altered visual feedback from an embodied avatar unconsciously influences movement amplitude and muscle activity

Evidence suggests that the sense of the position of our body parts can be surreptitiously deceived, for instance through illusory visual inputs. However, whether altered visual feedback during limb movement can induce substantial unconscious motor and muscular adjustments is not known. To address this question, we covertly manipulated virtual body movements in immersive virtual reality. Participants were instructed to flex their elbow to 90° while tensing an elastic band, as their virtual arm reproduced the same, a reduced (75°), or an amplified (105°) movement. We recorded muscle activity using electromyography, and assessed body ownership, agency and proprioception of the arm. Our results not only show that participants compensated for the avatar’s manipulated arm movement while being completely unaware of it, but also that it is possible to induce unconscious motor adaptations requiring significant changes in muscular activity. Altered visual feedback through body ownership illusions can influence motor performance in a process that bypasses awareness

Estimation of the Presence of Coal Using ANN Method by Employing the Geophysical Log Parameters at the Soma Basin

In this study, the feed forward, back propagation neural network model (ANN), used as one of the complex modeling systems and artificial intelligence methods, have been employed to estimate the presence of a coal layer at the Soma Coal Basin. Considering the costs of potential drillings, using ANN means advantages in terms of labour and cost. In this work, the neutron, gamma ray and density data are used as input parameters to the ANN system. For the study case, the geophysical well logs parameters of ten mechanically are drilled wells in the Soma Coal Basin are used. For four drilled wells, the best R and MSE values of 0.74 and 0.084 were estimated respectively. Whereas for each well separately values 0.81 and 0.051 were estimated. It is concluded that ANN given a good fit for the accurate prediction of the presence of coal layers from well log data. Furthermore, for modeling of reserves and estimation of coal layer characterization, ANN gives quick and highly accurate results

Prediction and optimization of tribological behavior of nylon composites using Taguchi analysis method

In this study, the tribological performance of graphite and wax filled nylon composites was predicted and optimized with the assistance of the Taguchi analysis method. Experimental data from our previous published work are handled. The experimental results are transformed into a signal-to-noise (S/N) ratio using the Taguchi method. This ratio presents the quality characteristics of the experimental results. Tribological performance of nylon 6 (polyamide 6) composites was predicted and optimized. The type of material, applied load, and sliding speed exert effects on the specific wear rate, at 85.06, 2.17, and 3.26, were obtained, respectively. Furthermore, the estimated S/N ratio using the optimum testing parameters for specific wear rate was calculated and a good agreement was observed between the predicted and experimentally determined values for a confidence level above 90

An investigation on physical, structural and gamma ray shielding features of Dy3+ ions doped Telluroborate glasses

WOS:000488998900041Structural, physical and gamma ray shielding properties of Dy3+ doped telluroborate glasses have been discussed. The molar volume of the glasses is proportional to the TeO2 content. The FTIR studies investigate the expansion of TeO(2 )content and the dynamic change of tetrahedral [BO4] units into trigonal [BO3] units. Using the absorption spectra, optical band gap (E-g) and Urbach's energy (Delta E) values are calculated. The molar volume of oxygen (V-O) and boron-boron separation () values are increasing while there is a fall in oxygen packing density (OPD) from 0% to 40% of TeO2. The ionic nature of the present glasses is analyzed from the bonding parameter (delta), optical basicity (Lambda(th)), covalent and ionic characteristic factors. The gamma photon attenuation investigated employing GEANT4 code. The transmission factor (TF) shows that OTBD sample (0 wt% of TeO2) has the highest TF, while the 4TBD sample (40 wt% of TeO2) has the lowest TF

Effect and control of pollution in catchment area of Lake Sapanca, Turkey

Land-based point and diffuse pollution sources in the catchment area of Lake Sapanca, Turkey, were investigated. The present and future distribution of pollution loads were evaluated in terms of nitrogen, phosphorus, biochemical oxygen demand, and pesticides. A methodology for the estimation of pollution loads was presented; most of which were based on "unit loads." Presently domestic End industrial point sources dominate over diffuse sources including fertilizers and pesticides from agricultural use, nutrient loads from forests and meadows, urban runoff, and leachates from unregulated dumps of solid wastes. For the future, the aim of the control action is to maintain the sustainability of the water quality of the lake, at least at the second class of European Community standards. Within this framework; urgent/short-term and medium/long-term control actions will be exercised. In the urgent/short-term stage, simpler and natural ways of treatment will be employed. In the medium/long-term stage an integrated collection and treatment system will be put on operation. After completion of a proposed collection system and treatment plants to handle point sources, the control of diffuse sources will be more significant. Control of diffuse sources for the abatement of further deterioration of water quality then becomes the key issue to be emphasized in the Lake Sapanca catchment area. Diffuse sources control will be achieved by dividing the catchment area into three major protection zones. Use of pesticides and fertilizers on agricultural land and all other activities within these protection zones will be accomplished according to control plans, which will be supervised by an institution established to be responsible of ail the activities within the basin

Towards an ınformation extraction system based on ontology to match resumes and jobs

2013 IEEE 37th Annual Computer Software and Applications Conference Workshops, COMPSACW 2013 -- 22 July 2013 through 26 July 2013 -- Kyoto -- 100165While Internet takes up by far the most significant part of our daily lives, finding jobs/employees on the Internet has started to play a crucial role for job seekers and employers. Online recruitment websites and human resources consultancy and recruitment companies enable job seekers to create their résumé, a brief written formal document including job seeker's basic information such as personal information, educational information, work experience and qualifications in order to find and apply for desirable jobs, whereas they enable companies to find qualified employees they are looking for. However résumés may be written in many ways that make it difficult for online recruitment companies to keep these data in their relational databases. In this study, a project that Kariyer.net (largest online recruitment website in Turkey) and TUBITAK (The Scientific and Technological Research Council of Turkey) have been jointly working is proposed. In this mentioned project, a system enables free structured format of résumés to transform into an ontological structure model. The produced system based on ontological structure model and called Ontology based Résumé Parser (ORP) will be tested on a number of Turkish and English résumés. The proposed system will be kept in Semantic Web approach that provides companies to find expert finding in an efficient way
