Sustainability is a concept which is addressed with environment and development concepts and it aims the healthy transfer of natural resources to future generations. For these aims environmental education is regarded as an important tool of sustainable development. In this respect, various methods have become popular in recent years in order to endow individuals with sustainable environmental education. One of these methods is field trips. A field trip is a process in which students’ abstract perceptions regarding the environment become concrete. In this research, the single–group pretest–posttest model, which aims to make measurements both before and after the experiment by applying an independent variable to a selected group, was employed. The sample of research consisted of 46 pre–service teachers in Ahi Evran University. Attitude and Behaviour Scale for Sustainable Environmental Education are used as data collection instruments. It was determined at the end of the research that the attitude and behaviour scores of the participant pre–service teachers had increased following the trip; however, the increase of behaviour scores was not significant. Therefore, it could be stated that organizing field trips is the best way of instilling sustainable environmental consciousness to pre–service teachers.

Cold–formed profiles were first used together with the partition elements of the inner space and with roof systems (rafter etc.) due to their light weight. Approximately 1000 residences were built in 1992 in USA by means of light steel systems made of these profiles; whereas, this figure exceeds 30.000 residences today. In addition to USA, this system is commonly used in Japan, Canada, Australia and Europe. This system is preferred mainly due to its light structure, easy production opportunities, fast assembly, as well as clean construction site conditions not leaving any waste. Light steel structure systems being compatible with flexible planning thanks to its basic design principles are appropriate for earthquake regions and low–income families with its easy and cheap production costs. This study classifies light steel systems as stick, panel and box systems and highlights numerous of plan and facades when designed with respect to the modular design principle and generation of many alternatives on the basis of plan schemes consisting of 2 modules and combination estimations based on 3 flats.In this paper light steel frame constructional building systems design in residential housing are examined from the beginning of design stage to using stage by production methods as stick, panel and box system. And examined also façade design, plan alternatives and sub systems design.

This study investigates applicability of data mining process in estimation of daily pan evaporation which is one of the fundamental elements in the hydrological cycle. Firstly, the models were developed by using autoregressive modeling frequently preferred in hydrological studies for Lake Eğirdir in the southern part of Turkey and it was shown suitability of the AR(3) model. Hence, the 1–day, 2–day and 3–day previous daily pan evaporation values of Lake Eğirdir were used to develop the other DM models. The correlation coefficient and root mean square error criteria were used for evaluating the accuracy of the developed models. When the results of developed models were compared to observed pan evaporation according to these criteria, it was determined that the AR(3) model is a little more appropriate to estimate of daily pan evaporation. Consequently, it was shown DM models are useful as they are based on only daily pan evaporation data and not included the meteorological parameters.

In the present study, the frequency response of skew and trapezoidal shaped single layer graphene sheets are studied via Kirchho plate theory. A four node Discrete Singular Convolution (DSC) method is developed for free vibration analysis of arbitrary straight–sided quadrilateral graphene. The straight–sided skew and trapezoidal graphene is mapped into a square graphene in the computational space using a four–node element. By using the geometric transformation, the governing equations and boundary conditionsof the graphene are transformed from hte physical domain into a square computational domain. Numerical examples illustrating the accuracy and convergence of the DSC method for skew and trapezoidal shaped graphene sheets are presented. New results for skew and trapezoidal shaped graphene have been presented, which can serve as benchmark solutions for future investigations.

Broomrapes are obligate root parasitic weeds and major constraint to many dicotyledon crops especially in Mediterranean agricultural lands. Due to the fact that no single control measure is able to control broomrapes in the field satisfactorily, integrated management is recommended in general. The use of of trap crops or catch crops is an important strategy for controlling the weeds; and allelopathic plants are also utilized for the control. Trap crops, also called false hosts, are plants which stimulate the germination of the parasite seed but cannot be infested and thus reduce the seed population in the soil. On the other hand, catch crops stimulate the germination of the parasite seeds at a high frequency and allow the development of the parasite. Seed bank of the broomrapes are decreased by destroying the catch crops before the seed creating period of broomrape begins (Sauerborn, 1991). Field trials were conducted using flax (Linum usitatissimum L.) as a trap plant; lentil (Lens culinaris L.) as a catch plant; members of the Brassicaceae species, such as cabbage (Brassica oleracea L.), Brussels sprouts (Brassica oleracea var. gemmifera (DC.) Thell.), broccoli (Brassica oleracea L. var. italica Plenck), cauliflower (Brassica oleracea var. botrytis L.), canola (Brassica napus L.) and turnip (Brassica rapa var. rapa L.) as allelopathic plant in the Adana province (Turkey) in 2007–2009. Flax was the most effective treatment by decreasing 52% and 71% in shoot number and 55% and 26% in dry weight of O. crenata in the first and second year, respectively. Broccoli of the Brassicaceae family, was found to reduce the number of O. crenata shoots by 48% and 39% in two years. Regarding the effect of Brassicaceae family on O. crenata, broccoli was found to reduce the number of O. crenata shoots by 39%. It is concluded that growing flax as a trap plant or lentil as a catch crop two months before the sowing of lentil as a crop is can be a main element of integrated broomrape managament, which cause to reduce the soil seed bank of crenata broomrape.

Eviscerated sea bass, Dicentrarchus labrax were irradiated by Cobalt–60 at commercial irradiation facility at dose of 2.5 and 5 kGy at 2–4°C. The influences of the irradiation on proximate, fatty acid and amino acid composition in cultured sea bass were investigated. Significant differences (P0.0.5) were found between non–irradiated and irradiated sea bass in terms of moisture, protein, fat, ash and carbohydrate contents. Total saturated and total monounsaturated fatty acid contents were 27.97–24.72% for non–irradiated sea bass respectively. The amonts of these two fatty acids in irradiated samples increased to 28.18–25.75% for 2.5 kGy and 29.08–28.54% for 5 kGy. Total polyunsaturated fatty acid content for irradiated samples was higher than non– irradiated samples. Aspartic acid, glutamic acid, asparagines, histidine, serine, glycine, arginine, alanine, tyrosine, cystine, methionine, lysine, hydroxyproline and proline contents for 2.5 and 5 kGy irradiated sea bass were significantly different (P0.05).

This study was performed to determine the optimum level of soybean meal diets for two banded sea bream for growth performance, nutrient utilization, body composition and serum biochemistry. Two banded seabream were fed five experimental diets which were formulated replace fish meal by soybean meal at 0, 20, 30, 40 and 50%. Up to 40% of dietary fish meal was successfully replaced with no growth depression. Whole body composition of two banded seabream was not affected by soybean meal inclusion level. Total protein, triglyceride and total cholesterol of fish fed the SM50 diets were significantly lower compared to fish fed the soybean free diet. On the other hand, serum glucose level significantly increased as dietary soybean meal inclusion increased. Results showed that 40% fish meal can be replaced in diets for the two banded seabream by defatted soybean meal. Further studies to determine the inclusion level of soybean meal more than 40% with amino acid or enzyme supplementation are needed.

This study describes the effects of different stocking densities on texture\colour characteristics, protein content \amino acid and lipid content\fatty acid composition of rainbow trout fillet. Stocking density was selected 5 (Group A), 15 (Group B), 25 (Group C) kg fish m−3. Tukey’s Multiple Comparison Test showed insignificant differences between measured size\weight measurement and condition factors. No significant differences were found between A and C groups for colour analysis (L* and a* value) and texture profile analysis (hardness, adhesiveness, cohesiveness and gumminess values) of rainbow trout fillets. The proximate composition analysis showed rainbow trout fillets from the A and C groups to exhibit higher values of moisture than the B group. Fish from the A and B groups had a lower of ash and protein in comparison to C group samples. The highest fat values of rainbow trout were measured in B group samples. The content essential amino acid and non–essential amino acid was lower in A and B groups than in C groups. Fish from the C group had higher content of polyunsaturated fatty acids, especially n–3, docosahexanoic acid (DHA) and eicosapentaenoic acid (EPA) in comparison to A and C group. As a result, 25 kg fish m−3 is recommended stock density in terms of product texture\color and composition quality.
