Ztekin, Ertekin Ö.
In the bolted connections, bolt placements are generally described and are generally made in the direction of design effects and in the perpendicular direction to design effects. In these both directions, the reliability of the distance of bolts to the edges of connection plate and the distance of bolts to each other is investigated for high strength steel connections built up with high strength bolts in this study. For this purpose, simple SL (bearing type shear connection) and SLP (bearing type shear connection for body-fit bolts) type steel connections with St 52 grade steel plates with 8 different thicknesses and with 8.8D grade high strength bolts (HV) were constituted and analyzed under H (Dead Loads+Live Loads+Snow Loads+ Roof Loads) and HZ (H Loads+Wind Loads+Earthquake Loads) loadings. Geometric properties, material properties and design actions were taken as random variables. Monte Carlo Simulation method was used to compute failure risk and the first order second moment method was used to determine the reliability indexes of those different distances describing the placement of bolts. Results obtained from computations have been presented in graphics and in a Table. Then, they were compared with some values proposed by some structural codes. Finally, new equations were constituted for minimum and maximum values of distances describing bolt placement by regression analyses performed on those results.

Das, Huseyin; Turan, Ibrahim; Demir, Selim
Genotypes have to be controlled periodically and necessary precautions should be taken in order to ensure that animal biodiversity is not lost. In this study, the genotypes of the Akkaraman, Karayaka and Morkaraman species from among Turkey’s local sheep were examined at 7 different microsatellite loci. The average allele counts are close to each other and were determined as 8,905±0,483. Whereas the PIC values ranged from between 0,507-0,794 at an average of 0,705. The He and Ho values used to calculate genetic diversity were determined on average as 0,734±0,023 and 0,509±0,038 respectively. According to the Fisher-Exact test result, the populations are not in HWE (P<0.001). Whereas the FIS values that show inter- population genetic diversity were determined as 0,353±0,092 (KRY), 0,328±0,095 (MRK) and 0,237±0,059 (AKK) respectively. In addition, Population Assignment and Principal Coordinate Analysis graphs were formed. When the pairwise FST and Nm, NeiuD,SHUA and G Statistics values used to calculate the genetic similarities and differences are examined, it is observed that the closest relations in terms of genetics is among AKK-KRY followed respectively by AKK-MRK and KRY-MRK.

Dioryctria sylvestrella Ratz. poses a remarkable hazard for the Pinus brutia Ten. in Turkey. In the current study, the larvae gallery resin of five trees and essential oils of resin, which was obtained with the AcidPaste Method, were analyzed using the Gas Chromatography and Mass Spectrometry (GC-MS) Method. Thirty nine compounds were found in larvae gallery resin, which were produced by Dioryctria sylvestrella Ratz, while thirty six compounds were extracted from oleoresin obtained by the Acid-Paste Method. The most common compounds of larvae gallery resin were α-pinene at a rate of 20.2%, β-caryophyllen at a rate of 10.8%, γ-terpinene at a rate of 10.1% and β-pinene at a rate of 9.4 percent. The most common compounds of oleoresin were α-pinene at a rate of 19.7%, β-pinene at a rate of 13.3%, γ-terpinene at a rate of 10.2% and β-caryophyllen at a rate of 7.8 percent. Also, the quantities of some compounds within larvae gallery resin such as β-pinene, limonene, and sylvestrene decreased compared to those of oleoresin, while the quantities of some compounds in oleoresin including α-longipinene, α-terpineol, and longifolene increased compared to that of larvae gallery resin. However, no qualitative difference was found.

Bayram, Bahri; Topal, Mehmet; Aksakal, Vecihi; Önk, Kadir
A total number of 947 calving records from 613 Holstein Friesian cows raised at a private dairy farm in Kelkit, Turkey, from 2004 to 2006 were used to study the effect of non-genetic factors on calving difficulty and stillbirth rate using CHAID algorithm. The mean calf birth weight was 41.0±0.19 kg. The overall incidence of calving difficulty and stillbirths in the Holstein Friesian herd were 9.1% and 9.4%, respectively. Calf birth weight, birth type and calving season had the greatest impact on calving difficulty. The increase in calf birth weight was associated with a significant increase in calving difficulties (P<0.01). The calving difficulty risk in twins (18.9%) was higher than in singleton calves (5.0%). The main environmental variables affecting the stillbirth rate were parity number, calf birth weight, sex of calf, calving season and calving difficulty. Parity number was statistically the most relevant factor affecting the stillbirth rate, which was also higher in primiparous (18.7%) than in multiparous cows (5.4%). As the calf birth weight increased, a significant increase was also in the stillbirth rate (P<0.01). The stillbirth rate in winter (19.7%) was higher than in other seasons (3.6%) (P<0.01). Calving assistance was associated with an increased risk of stillbirth (P<0.05). As a result, calf birth weight, birth type and calving season had the greatest impact variables on calving difficulty, however, parity, calf birth weight, sex, calving season and calving difficulty were the most effective variables on stillbirth in Holstein Friesian Cattle.

Gunaydin, M.; Adanur, S.; Altunisik, A.C.; Sevim, B.
In recent years, the use of fiber reinforced polymer composites has increased because of their unique features. They have been used widely in the aircraft and space industries, medical and sporting goods and automotive industries. Thanks to their beneficial and various advantages over traditional materials such as high strength, high rigidity, low weight, corrosion resistance, low maintenance cost, aesthetic appearance and easy demountable or moveable construction. In this paper, it is aimed to determine and compare the geometrically nonlinear static and dynamic analysis results of footbridges using steel and glass fiber reinforced polymer composite (GFRP) materials. For this purpose, Halgavor suspension footbridge is selected as numerical examples. The analyses are performed using three identical footbridges, first constructed from steel, second built only with GFRP material and third made of steel-GFRP material, under static and dynamic loadings using finite element method. In the finite element modeling and analyses, SAP2000 program is used. Geometric nonlinearities are taken into consideration in the analysis using P-Delta criterion. The numerical results have indicated that the responses of the three bridges are different and that the response values obtained for the GFRP composite bridge are quite less compared to the steel bridge. It is understood that GFRP material is more useful than the steel for the footbridges.

Yilmaz, Murat; Usta, Ayhan; Çakir, Günay; Kahveci, Seda Nur Ince
Erodibility indices together with other soil properties of Atasu Dam watershed in Trabzon, Turkey, were analyzed according to land use regimes (grassland, cultivated land, coniferous forest land and broadleaf forest land) and the granite parent material from which the soil develops. The findings could be applied to future management plans with the aim of enhancing the ability of Atasu Dam to supply water for drinking, domestic use and irrigation to the region. Forty sample plots having the same northern aspect were selected from bordering lands. Cross-section soil samples from depth levels of 0-10 cm and 10-30 cm were gathered from the selected sites. Particle size distribution, soil organic matter (SOM), dispersion ratio (DR), erosion ratio (ER), colloid-moisture equivalent ratio (C-MER), structural stability index (SSI), water dispersible clay (WDC), clay dispersion ratio (CDR), clay flocculation index (CFI), exchangeable cations, exchangeable sodium ratio (ESR), sodium adsorption ratio (SAR) and soil reaction (pH) analyses were performed. A variance analysis was carried out in order to determine if the obtained results varied according to land use type. Soil samples from a variety of sites in areas with granite as parent material were applied to erodibility indices and the sites were found to be susceptible to erosion. Some other characteristics were also found to be effective on the erodibility indices, including the relationship of soil organics, which was also considered to be to a factor of interest in this study. Soils that were developed from granite parent material in areas covered by forest were observed to be more susceptible to erosion. These results were fairly significant in the context of the study area of the Galyan-Atasu Dam watershed. This study suggests that incorporating these findings in planning and management-related activities can potentially lead to improvement of the basin and contribute to the economic life of the dam.

This study was carried out to determine whether butter can be a carrier for probiotics by observing the survivability of selected probiotic strains during cold storage. The effects of using probiotic adjunct cultures (Lactobacillus acidophilus ATCC 4356 and Bifidobacterium bifidum ATCC 29521) in butter on microbiological counts, sensory characteristics, chemical characteristics and free fatty acid (FFA) composition during storage for 60 days were investigated. The butter samples produced with B. bifidum ATCC 29521 maintained the probiotic characteristics, in that the level of viable cells of the probiotic was >106 cfu g-1 until 30 days of storage. The highest scores in sensory assessment were obtained on the first day of storage. FFAs, including C2:0, C6:0, C14:0 and C18:1, were affected significantly by storage period and by the adjunct cultures, however conjugated linoleic acid and C18:2 were not affected by storage period and the use of probiotic adjunct culture.

Yuksel, F.; Karaman, S.; Kayacier, A.
In the present study, wheat chips enriched with barley flour at different concentrations (5, 10, 15, 20, 25 and 30%) were produced and some physicochemical and textural properties, fatty acid composition and sensory quality of enriched chips were investigated. An increase in the values of some physicochemical parameters of wheat chips, namely hardness, dry matter, ash and some fatty acids levels, was observed with the increasing barley flour concentration in the formulation. Barley flour addition provided a significant oil uptake reduction as the oil content of the control sample was 27.23% while that of the enriched samples with 30% barley flour was 18.21%. Overall acceptability of wheat chips added with no barley flour samples was determined to be similar to compared to enriched ones. But addition of barley flour higher than 10% caused a decrease in sensory scores of the final products.

Köroğlu, Cemile Zehra; Köroğlu, Muhammet Ali
In all societies, there have been some movements that point out social, political, economic, ideological, or moral problems or aim at partial or complete change. This chapter discusses the new meanings attributed to the concept of social movements in the postmodern era. A theoretical framework is proposed to understand the nature of social movements since the 1960s and to demonstrate their differences from classical movements. Turkey provides a particularly rich context with high potential for social movements, both with secular and religious aspirations. Religious social movements have shown quite a tense relationship with the state throughout the history of the republic; yet, they have gained power and prosperity through evolving liberal economic policies since the 1980s. Therefore, resource mobilization and new social movement paradigms are used in this chapter to explain Turkey’s religious social movements today.

Objective: The purpose of this study was to show the association between oxidative stress and deep venous thrombosis (DVT) by determining total oxidant status (TOS), total antioxidant status (TAS) and oxidative stress index (OSI) values in patients with DVT and to take precautionary measures to balance oxidative status. Methods: TOS, TAS and OSI levels in serum from 52 individuals with DVT and 45 without DVT were compared. Results: TOS and OSI levels were significantly higher in patients with DVT compared with the control group (p<0.0001), but no difference was observed in TAS levels (p=0.118). The patient group was divided into two subgroups, idiopathic and secondary DVT. TOS and OSI levels were significantly higher patients with both idiopathic DVT and secondary DVT compared to the control group (p<0.0001). TAS levels were significantly higher in patients with idiopathic DVT than in the control group, but no difference was observed in the patients with secondary DVT. Conclusion: Specificity and sensitivity values obtained from the receiver operating characteristic (ROC) curve show that TOS and OSI are both markers that can be used in the diagnosis of DVT. Also, determination of oxidative stress markers may guide clinicians to take necessary precautions to balance oxidative stress in the patients.

Nemli, Seda; Kutlu, Burcu; Tanyolac, Bahattin
The common bean (Phaseolus vulgaris L.) is an important food legume throughout the world. Because of the conservation across different plant species, it is possible to evaluate the degree of genetic diversity in the common bean using gene-based marker techniques. The lipoxygenase (LOX) and resistance gene analog (RGA) genes play an important role in the response to biotic and abiotic stresses. Eighty-six common bean accessions were genotyped using gene-based LOX and RGA markers. The total number of polymorphic bands ranged from 193 for LOX to 17 for RGA markers. We detected considerable diversity with a mean of 8.7 alleles per primer for the LOX analysis. For the RGA markers, the number of alleles per polymorphic locus varied from 1 to 4 with an average allele number of 2.8. The genetic similarity between the accessions based on the LOX and RGA markers ranged from 0.12 to 0.55. Using STRUCTURE, 3 groups were revealed among the accessions. The results of this study should provide valuable information for future studies on the genetic diversity of common bean accessions and for association mapping studies examining the relationships between the genotypic and phenotypic traits related to the stress response.

Sunflower (Helianthus annuus L.) having shorter growing season, better cold tolerant and more drought resistant is important alternative silage plant in highlands. But it has poor silage quality. To improve the quality of sunflower silage can be mixed an appropriate amount of corn (Zea mays L.) and alfalfa (Medicago sativa L.). This research was carried out to evaluate quality characteristics of nine silage types: Sunflower, corn and alfalfa silages; plus their some mixtures silages (75% sunflower + 25% corn, 50% sunflower + 50% corn, 25% sunflower + 75% corn, 75% sunflower + 25% alfalfa, 50% sunflower + 50% alfalfa and 25% sunflower + 75% alfalfa); at two harvest stages: Beginning of flowering for sunflower and alfalfa and milk-dough stage for corn (early stage), and end of flowering stage for sunflower and alfalfa, and dough stage for corn (late stage). The experimental design was in a factorial arrangement of randomized complete block with replicated four times. Dry matter content (DM), crude protein content (CP), neutral detergent fiber content (NDF), acid detergent fiber content (ADF), silage pH and physical characteristics (PC) of silages were determined in this study. Mixing of alfalfa in NDF, ADF and CP and corn in DM, pH and PC had positively effect in sunflower silages. Late stage had positively affected DM, PC and pH for silage. Consequently, sunflower silages mixed with corn, with the condition of not being less than 50% at late stage, are recommended for farmers.

Lactoperoxidase (LPO) catalyzes the oxidation of numerous of organic and inorganic substrates by hydrogen peroxide. It has very vital activity in the innate immune system by decreasing or stopping the activation of the bacteria in milk and mucosal secretions. This study's purpose was to investigate in vitro effect of some phenolic acids (ellagic, gallic, ferulic, caffeic, quercetin, p-coumaric, syringic, catechol and epicatechin) on the purified LPO. This enzyme was purified from milk by using different methods such as Amberlite CG-50 resin, CM-Sephadex C-50 ion-exchange and Sephadex G-100 gel filtration chromatography. LPO was purified 28.7-fold with a yield of 20.03%. We found phenolic acids have inhibition effects on bovine LPO enzyme to different concentrations. Our study showed lower concentrations of caffeic acid, ferulic acid and quercetin exhibited much higher inhibitory effect on enzyme, so these three of them were clearly a more potent inhibitor than the others were. All of compounds were non-competitive inhibitors.

The aim of this study was to evaluate the possibility of using hazelnut slurry in manufacture of yoghurt. A yoghurt-like product was prepared from hazelnut slurry fortified with skimmed milk powder. The effects of the total solids content of the hazelnut slurry (TSCHS, 8-16g100g-1) and the content of milk powder (CMP, 6-9g100g-1) on the proximate composition, physicochemical and sensorial properties, fatty acid composition, total phenolic content (TPC) and antioxidant activity of the product were evaluated using response surface methodology. Both the TSCHS and the CMP had a significant effect on the total solids content, b value, syneresis, palmitic and oleic acid content, and FRAP value. Only the TSCHS showed a significant effect on the protein and fat content, a value, water-holding capacity, TPC and ABTS values. Only the CMP showed a significant effect on the carbohydrate and ash content and the acidity. The characteristics of the product generally appeared to be compatible with those of yoghurt. The product was rich in unsaturated fatty acids. Therefore, using hazelnut slurry in manufacture of yoghurt may be proposed to enhance the health benefits of yoghurt.

The common bean (Phaseolus vulgaris L.) is an important crop throughout the world and is highly recommended for many developing countries due to its nutritional components. A retrotransposon-based DNA marker system, interprimer binding sites (iPBSs), developed from reverse transcriptase primer binding sites, was used to determine genetic diversity in common bean accessions. The genetic polymorphism and effectiveness of the marker system were evaluated. A total of 180 polymorphic bands were detected using 47 iPBS primers among 67 common bean accessions, with an average of 4 polymorphic fragments per primer. The genetic similarity between accessions was calculated using the software NTSYS-pc and ranged from 0.09 to 0.99. The average polymorphism information content value for the iPBS markers was 0.73. A model-based clustering method classified the common bean accessions into 4 populations using STRUCTURE software. The results indicated that the iPBS marker method can successfully determine the genetic diversity level in common bean accessions.
