Bu çalışmanın amacı, Karayaka koyunlarında dönem içi gonadotropin salgılatıcı hormon (GnRH) uygulamasının kızgınlık gösterme oranı ve ovaryum aktivitesi üzerine etkisini belirlemektir. Çalışmada en az iki doğum yapmış ve benzer vücut ağırlığına sahip 20 baş Karayaka ırkı koyun hayvan materyali olarak kullanılmıştır. Deneme başında tüm koyunlara ovaryum üzerinde mevcut olabilecek olan korpus luteum (CL)’un yıkımı için 1 ml PGF2α kas içi enjekte edilmiştir. PGF2α uygulamasından 9 gün sonra ise koyunlar rastgele iki eşit gruba ayrılmıştır. Birinci gruptaki koyunlara (n=10) 40 mg flugestone asetat içeren sünger vajina içine yerleştirilmiştir ve bu uygulamadan 14 gün sonra süngerler çıkartılarak, 1 ml PGF2α kas içi enjekte edilmiştir. PGF2α enjeksiyonunu takiben 36 saat sonra 1 ml GnRH kas içi enjekte edilmiştir. İkinci gruptaki koyunlara (n=10) ise mevcut olabilecek olan korpus luteum (CL)’un yıkımı için 1 ml PGF2α kas içi enjeksiyonun dışında herhangi bir uygulama yapılmamış olup, bu grup çalışmamızın kontrol grubunu oluşturmuştur. Bu işlemleri takiben her iki gruptaki bütün koyunlar Karayaka koçuna verilmiş ve 72 saat boyunca kızgınlık gösteren koyunlar belirlenmiştir. Kızgınlık taramasının sonunda bütün koyunlar kesime sevk edilmiş ve her iki ovaryum üzerindeki küçük (1-3 mm), büyük (>3 mm) ve toplam folikül sayısı ve CL sayısı belirlenmiştir. GnRH uygulaması yapılan koyunlar (%100) kontrol grubundaki koyunlara (%70) göre daha yüksek oranda kızgınlık göstermişlerdir. GnRH uygulaması yapılan koyunların her iki ovaryumundaki küçük ve toplam folikül sayısının ve CL sayısının, kontrol grubundaki koyunlarınkinden daha yüksek olduğu tespit edilmiştir. Ancak büyük folikül sayısı bakımından deneme grupları arasında bir farklılık tespit edilmemiştir. Sonuç olarak bu çalışmada mevsim içi dönemde Karayaka koyunlarında sünger uygulaması sonrasındaki GnRH uygulamasının kızgınlık gösterme oranını yükselttiği ve ovaryum aktivitesini arttırdığı tespit edilmiştir.

In this study, the effects of air-conditioning system on tractor performance and specific fuel consumption were examined and evaluated by experimental data. Loading performed from tractor power take-off in periodically by electrical dynamometer. Fuel consumption were measured in air-conditioning off and air-conditioning on usage and comments were discussed according to these values. In same speed and loading, measured specific fuel consumption value when the air conditioning is on more than measured specific fuel consumption value when the air conditioning is off. Torque values were measured and fuel power and power take-off power were calculated, these values were compared, comments were discussed according to these values. In same speed and loading, measured power take-off efficiency values when the air conditioning is on less than measured power take-off efficiency values when the air conditioning is off. This change is determined respectively as average 4.37%, 4.34% and 8.63% negatively for the measured three brand tractors. As a result of all data, the positive effect of air-conditioning usage on specific fuel consumption, the negative effect of air-conditioning usage on power take-off efficiency were determined.

The aim of this study is to evaluate the thought of food security provided in dairy products and the determinants in terms of manufacturers in South Marmara Region in Turkey. The primary data obtained from 70 dairy manufacturers were analysed by Factor Analysis and Logistic Regression Analysis. According to this, price fluctuation and increase in the distance from the place where the milk is provided, reasons such as corporatization are factors that cause the lack of food security in dairy products. On the contrary, the likelihood of providing food security in dairy products increases with the increase in financial sustainability, food safety, quantity of milk and dairy products, the ability to produce and store, the number of employees, the degree of milk use.

To examine polyamines (PAs) effect in modulating the drought induced by polyethylene glycol (PEG) in maize (Zea mays L.) seedlings (variety Khoibhutta, 8 day seedlings grown in petri dish in incubator) were subjected to 20% PEG (polyethylene glycol) followed by 20 µmol PAs, Putrescine (Put), Spermidine (Spd) and Spermine (Spm) with PEG solution for 48 hours. Sharp decrease in Relative Water Content (RWC), Chl a, Chl b, carotenoid (Car) and total pigment content was observed under drought compared to control condition, while PAs application reversed their decreasing trends. PEG significantly increased Reactive Oxidative Species (ROS) [superoxide (O2•−) and H2O2], Methyl Glyoxal (MG), Melondialdehyde (MDA) and Lipoxigenase (LOX) activity, while Pas decreased the contents considerably (except MG) as compared to those under drought. Drought increased proline content, which was further augmented in PA treatments. PAs failed to incline glyoxalase’s (Gly-I and Gly-II) activities, reduced under PEG. The activity and western blot confirmed the accumulation of Glutathione S-Transferase (GST) under drought, but PAs failed to augment the activity. Ascorbic Acid (AsA) and Glutathione (GSH) got oxidized into Dehydroascorbate (DHA) and oxidized Glutathione (GSSG) under drought but PAs effectively maintained homeostasis. Superoxide Dismutase (SOD), Peroxidase (POD), Ascorbate Peroxidase (APX), Glutathione Peroxidase (GPX), Monodehydroascorbatereductase (MDHAR), Dehydroascorbatereductase (DHAR), and Glutathione Reductase (GR) inclined in drought stressed seedlings, while Catalase (CAT) activity decreased under drought. PAs addition increased SOD, POD, GPX, CAT, MDHAR, and GR activities, but declined DHAR activity. These findings suggested important role of PAs in increasing tolerance under short term drought by modulating antioxidant effect.
