This research has been carried out to determine the effects of the current misinformation (hormone, antibiotic, feed additives and growth of broiler chickens in a short period) on consumers' view of the poultry meat sector. The survey was conducted in Istanbul province which better reflects the socio-cultural and socio-economic structure of Turkey, and with different demographic structure of 384 people face to face survey method was applied. Questions were asked to determine whether antibiotics and hormones were used in the diet of broiler chickens, and consumers' perceptions, attitudes and behaviors about the reliability of chicken meat. According to the results of the study, 73.4% of the consumers stated that they did not know about the contents of broiler diets. A big majority of the consumers (88.3%) stated that they think hormone is used and 84.6% think antibiotics is used in the feeding of broiler chickens. 78.4% of consumers surveyed stated that they think that broiler chickens are not fed with healthy feed. Also, 70.6% of consumers stated that rapid growth was due to use of antibiotics and hormones. Although the use of hormones and antibiotics as growth promoters in poultry feeds is prohibited, consumers think that they are used as additives and broiler meat is not safe food. According to these results, creating a positive effect on the purchasing decisions of the consumers is important for the sustainability and future of the sector.

This scale-wide participatory evaluation was designed to assess farmers’ technology preference and stakeholders’ linkage on top of estimating the advantage and efficiency of improved faba bean technology over the local practice. On-farm experiment and assessment were conducted using 100 farmers who allocate 0.25-0.5ha of land in Wag-lasta dryland. Planting and other agronomic standards were applied as per the technological recommendation. Required quantitative and qualitative data collected at farm and farmer level using quadrants and checklist, respectively. Cost-benefit analysis, descriptive and inferential statistics were employed to analyse the quantitative data. Qualitative data such as farmers’ technology preference and stakeholders’ linkage were assessed in simple ranking matrix and SWOT analysis. The improved faba bean technology provided mean grain yields of 1340 and 590 kg ha-1 in Lasta and Sekota districts, respectively. It has thus a 31.4% and 38.9% yield advantage and penalty over the local practice, in that order (p

Determining the potential bioavailability of heavy metals, evaluating according to adapted regulations is essential to efficiently conserve our coastal and estuarine waters. In this study, it is aimed to determine the industrial pollution and various other pollution sources that the Black Sea Basin is exposed to by using DGT (Diffusive Gradients in Thin Films) method and grab (manuel) sampling method in water and sediment and to evaluate the existing pollution according to quality standards. In Samsun, seasonal samples were collected from five different sampling stations, namely Akkiraz Stream, Hıdırellez Stream, Organized Industrial Zone (OIZ) Channel, Şabanoğlu Stream and Selyeri Stream, which are selected from Tekkeköy region where industry is intensively active. In order to determine the heavy metal content in both water and sediment samples, the DGT method was chosen for passive sampling and the grab sampling method was used for active sampling, and the efficiency of the methods was evaluated. According to the results of the study, the heavy metal concentration in grab sampling for water samples in descending order Al> Fe> Zn> Pb> Ni> Cu; In the samples taken with DGT, they are listed as Al> Fe> Zn> Cu> Ni> Pb. There were significant relationships between the total metal concentrations of sediment (Csed) and water (Csu) in grab sampling and metal concentrations sediment (Csed-DGT) and water (Csu-DGT) measured by DGT. It was found that the sensitivity and performance of sampling with DGT was 2-10 times higher compared to grab sampling. The high resolution in situ DGT technique for the assessment and management of the potential release risk of heavy metals at the water-sediment interface is a complementary method that contributes to the standard grab sampling method.

Spices and herbs are groups of vegetables with important properties for human health and food industries. They are generally consumed in cooked recipes and such treatment may affect the content of vital components such antioxidants. This study aimed at evaluating the effect of the cooking temperatures on total phenolics, flavonoids and vitamin C of some spices and herbs used in the locality of Bamenda, Cameroon. Briefly, the most consumed spices and herbs were selected through structured questionnaires administered to individuals involved in their consumption and selling. Thereafter, samples were collected and subjected to different boiling treatments and the levels of the antioxidants (flavonoids, phenols and vitamin C) were determined. Results showed that almost half the participants (48%) used Parsley, Basil, White pepper, Njansa, Mint and African nutmeg mainly for flavoring and medicinal purposes. The cooking temperature of 65°C increased total phenolics and flavonoids in spices (Mint, White pepper, Njangsa and African nutmeg) and herbs (Parsley, Basil) while higher heat treatments (75 and 85°C) lowered the content of these pytochemicals. Boiling of spices or herbs significantly and temperature dependently reduced the vitamin C content in all spice and herb samples with respect to the control raw samples. Summarily, the moderate boiling (65°C) treatment used by the local populations favors release of total phenolics and flavonoids though with some reducing effect on vitamin C.

In this study, the effect of different phosphorus doses application on the yield and nutrient uptake of sugar beet plant was investigated under field condition. The study was carried out in Sivas province in 3 replications according to the randomized plot design and Valentina was used as the sugar beet variety. Phosphorus doses were; 0 kg P da-1, 15 kg P da-1, 30 kg P da-1 and applied as triple super phosphate (TSP). Leaf samples were taken approximately 80 days after the planting of sugar beet plant, nitrogen (N), phosphorus (P), potassium (K), calcium (Ca), magnesium (Mg), iron (Fe), zinc (Zn), manganese (Mn), copper (Cu) concentrations and yield were determined at harvest. Research results indicated that the yield increased depending on the increasing phosphorus doses and the highest yield was obtained at 30 kg P da-1 dose with 8151.0 kg da-1. In addition, the highest nitrogen, phosphorus and potassium concentrations were found at 30 kg P da-1 dose (4.77% N, 0.74% P and 2.39% K, respectively). However, the research found that calcium and magnesium concentrations decreased with increasing phosphorus doses. While only iron concentration among microelements increased with phosphorus applications, zinc, manganese and copper concentrations decreased due to increasing phosphorus doses.

The sculpture, which is the expression of beliefs and fears in prehistoric times, has taken on different roles as an urban reinforcement element in all cultures with numerous themes. In the Middle Ages, it became an organic part of the architectural structure, teaching the truth about religious beliefs. With the Renaissance movement, it became independent by breaking away from the architectural structure and moved to the urban space. In the twenty-first century, its dimensions have grown to be equivalent to architecture, it has created its own space and established new aesthetic and functional relations with the audience. In this study, the relationship of some sculptures on the Alaeddin Keykubat campus of Selcuk University with the landscape elements was examined in terms of design elements and basic design principles. In the light of the data obtained, suggestions have been developed in order to increase the life and aesthetic quality of the campus.

Within the scope of this research, the chronic effects of ammonium nitrate, which is the most widely used fertilizer worldwide, on the tadpoles of Marsh Frog (Pelophylax ridibundus), the Iranian Long-Legged Frog (Rana macrocnemis), the Caucasian Parsley Frog (Pelodytes caucasicus) and the Variable Green Toad (Bufotes variabilis) were examined. To assess the chronic effects of the fertilizer, the tadpoles of all the species were exposed to 0, 5, 10, 15, 20, 25 mg/L concentrations in same conditions. The chronic concentrations were applied from the 25th developmental stage to the 42nd developmental stage. It was defined at the end of the experiments that although there were some variability between different populations of the same species or between different species in the observed effects, chronic levels of ammonium nitrate caused decreased growth rate, prolonging in time to complete metamorphosis, increased abnormalities, and mortality in general. Among the 4 amphibian species, the Variable Green Toad was the most damaged one in terms of growth reduction (on average 31-41 %), abnormality rates (on average 50-75 %), prolonged time to complete metamorphose (14-21 days on average) and mortality rates (%54-100). The most adaptive species and the least damaged one was an Iranian long-legged frog for growth reduction (on average 0-15 %), prolonged time to complete metamorphose (7-9 days on average), and mortality rates (%9-15). All the harmful effects of chronic fertilizer levels caused by agricultural activities in the region had very important for examined species in our researches and it can be said that important environmental and biodiversity problems may occur if certain precautions are not taken regarding the use of the fertilizers and if the attitudes of the farmers on this issue cannot be changed.

In this study, the performance, egg quality, egg yolk colour and fatty acids profile of quails fed on diets containing different fat sources were determined. During 8 weeks trial, a total of 75, 10-weeks-old laying quails were used. Three diets were formulated to contain soybean oil (SBO), sunflower oil (SFO) and hempseed oil (HSO), respectively. The performance parameters were not significantly influenced by the dietary different oil sources. Eggshell ratio, eggshell thickness, eggshell breaking strength, egg shape index, egg yolk index, albumen index and egg yolk colour values (except a*) were not influenced by the different dietary oil sources. The a* value was significantly affected and the highest a* value was the HSO of group. The different oil sources supplementation to the diets was effective on fatty acid composition of the egg yolk. The highest value in terms of α-linolenic acid, total polyunsaturated fatty acids and total n-3 fatty acids were found in the diet fed group with HSO added. As a result; supplementation of different sources of oil to quail diets without negatively affecting performance and egg quality can be used to change the egg yolk fatty acid composition. Hempseed oil may increase the amount of total polyunsaturated fatty acids and total n-3 fatty acid content of egg yolk.
