Belediye çöplüğü olarak adlandırılan ve çöplerin düzensiz olarak depolandığı alanlar çevrenin yaşam kalitesini düşürmesinin yanında toprağa ve su kaynaklarına zarar vermektedir. Bu alanların en önemli etkisi depolanan çöplerin içerdiği zararlı maddelerin çevreye yayılması, toprakta birikmesi ve taban suyuna karışmasıdır. Bu çalışmada uzun yıllardır düzensiz çöp depolama alanı olarak kullanılmış olan Çorlu düzensiz çöp depolama alanının, yakınında bulunan tarım alanlarına kirletici etkisi incelenmiştir. Bu amaçla depolama alanı ile Çorlu deresi arasında kalan ve tarım yapılan alandan örneklemeler yapılmıştır. Çöp depolama alanına farklı mesafede 22 noktadan ve 3 farklı derinlikten toplam 66 toprak ve 14 bitki örneği alınmıştır. Toprak ve bitki örneklerinde Magnezum (Mg), Potasyum (K), Kalsiyum (Ca), Fosfor (P), Demir (Fe), Mangan (Mn), Bakır (Cu), Çinko (Zn) analizleri yapılmıştır. Ayrıca verilerin daha kolay anlaşılırlığını sağlamak için, Coğrafi Bilgi Sistemleri (CBS) yardımıyla makro ve mikro elementlerin dağılım haritaları yapılarak, toprak ve bitkide bulunan miktarların daha kolay anlaşılabilirliği sağlanmıştır. Analiz sonuçlarına göre toprakların element içerikleri ile çöp alanı arasında mesafe ile ilgili bir ilişki bulunamamıştır. Araştırma alanının eğimli olması ve bahar yağışlarının topraklarda yıkanmaya neden olması toprakların element konsantrasyonunun değişmesine neden olmuştur. Ayrıca çalışma alanının tekstürü kumlu tından kile kadar değişiklik göstermektedir. Toprak analiz sonuçları kil içeriği yüksek olan noktalarda element konsantrasyonlarının nispeten yüksek olduğunu göstermektedir. Toprakların kirlilik sınıflandırmasına göre tehlikeli metaller içinde yer alan Cu ve Zn sınır değerleri aşmamıştır. Bitkilerde ise Fe hariç Mn, Cu ve Zn içerikleri sınır değerleri aşmamıştır.

Pulses in Pakistan is used in combination with cereals to balance the diet. Its area and production is decreasing for last many years. In the barren and partly arid regions, water shortage is the major component that restricts yield. Using of drought resistance plant is one of the best ways for good cultivation under drought condition. As the pulses have great nutritional and economical values and drought stress affect their morphological features. The legume yield is mostly cultured in rain fed region of the Punjab where they bear a slighter quantity of water situation resulting in low yield of bean. To overcome these problems it is necessary to get knowledge about the performance of different lines of different pulses crops under water stress conditions. That’s why in this paper the information about the previous literature has been discussed.

The aims of this study were to evaluate the traits of reproductive, milking and growth performance of Saanen and Saanen × Hair crossbreds (F1, B1 and B2) raised at the Bandırma Sheep Research Institute. The data were collected from 868 goats for reproductive performance and milk yield and from 1077 kids for survival performance between 2009-2012. Milk components (fat, protein, lactose and non-fat dry matter) of goats (n=162) and body weight changes of kid’s (n=64) were evaluated for one year in 2012. Estrus rates and survival rates were similar among all genotypes. Kidding rate was significantly higher in F1 goats than Saanen goats. Saanen goat had the lowest average mean daily milk yield compared with other genotypes. The effect of year and age were significant on milk yield. Goats in F1 and B1 genotypes had higher milk protein percentage and non-fat dry matter content in comparison with Saanen and B2 genotype. Milk fat and lactose contents were similar among genotypes. Birth weight and monthly live weight were similar between genotypes while weaning weight, six month live weight and yearling live weight were higher in B1 kids in comparison with Saanen kids. The effect of dam age and birth type were significant on birth weight, monthly live weight and weaning weight. The findings related to performance characteristics in goat genotypes investigated show that B1 genotype could be recommend for semi-intensive production system in the Western Anatolia.

The aim of this study was to determine students' consumption behavior based on their awareness of food safety. Data were collected using survey method. Study sample consisted of 400 students of Ünye Faculty of Economics and Administrative Sciences, Ordu University, Turkey. Chi-square test was used to determine whether participants’ levels of awareness of food safety differed by socio-economic characteristics. One-way analysis of variance (ANOVA) was used to determine differences in mean scores among awareness groups (low, medium and high) in terms of reading the nutrition information on food labels, food purchasing venues to be reliable and factors affecting food purchase decisions. Results showed that expiry date was the most important factor in food purchase decisions, followed by dates of production and packaging. Participants’ levels of awareness of food safety significantly differed by the proportion of monthly income allocated to food and their preference for cheap foods containing GMO. Supermarkets were ranked the most reliable venues for safe food purchasing, followed by groceries and greengrocers. Results also showed that food purchase decisions of the low and medium awareness groups were mostly affected by their families while those of the high awareness group were mostly affected by their doctors. Results indicate that firstly parents' awareness should be raised about food safety and safe food consumption so that future generations can be more conscious of these issues. In addition, courses on these matters should be included in curricula, and seminars or workshops should be held to raise students' awareness of food safety.

Ece Söğüt
The increase of consumer demand for using natural products and reducing the use of non-compostable packaging materials have encouraged research on biodegradable polymers including natural components such as essential oils. Pomegranate seed oil (PSO) has active properties such as antimicrobial and antioxidant activities. The aim of this study was to prepare active polycaprolactone (PCL) films by using PSO. PCL films including PSO emulsions (5-30%), which were stabilized with nanocellulose (NC) particles, were prepared by casting method. The physical and active properties of PCL films were determined by means of water vapor permeability (WVP), mechanical properties, optical properties, release behaviour, and potential antimicrobial activity. The WVP values of PCL films was lower when incorporated with NC-stabilized PSO emulsions. The incorporation of PSO into PCL films in the form of NC-stabilized emulsions significantly reduced the transmittance and lightness values, which resulted in an increase in opacity. In the release tests, the slower release of PSO was observed for NC-stabilized films. The stabilization of PSO with NC showed to be less effective when high concentrations of oil (30%) were used. Film samples showed potential antimicrobial activity against Escherichia coli, and Listeria monocytogenes, however, a clear zone of inhibition around the film samples was not detected. Results also suggested that the antimicrobial effect was dependent on two important factors: the release behaviour of PSO through the film samples and, the direct interaction between PSO and microorganisms. These results showed that the combination PCL films and PSO stabilized with NC could be an interesting approach in active packaging technologies.

Ali Kozlu | Yeşim Elmacı
Today’s consumers prefer foods with high nutritional value, functional properties and long shelf life. Particularly, interest in fresh fruits and vegetables, which are ready for consumption due to their healthy and nutritious nature, is increasing. However, biological activities such as respiration and transpiration cause loss of water and soluble substances in fruits and vegetables and change the gas concentration in the environment during storage and this situation greatly affects critical quality parameters such as mass loss, nutritional value and shelf life. Minimal processing, such as peeling, cutting or shredding increases the surface area of fresh fruits and vegetables, reduces the shelf life by triggering a variety of enzymatic reactions. The edible film coating is a novel packaging method that is natural, environmental friendly, economic and easily applicable. This innovative technique can be used to produce a product that is closest to fresh fruits and vegetables, maintain the desired quality characteristics, control microbiological spoilage and extend the shelf life. In addition, the use of plant-based materials in film coating applied to minimally processed fruits and vegetables attracts the consumers and increases the confidence in products. In this review, the information about the current applications of edible coating to the minimally processed fruits and vegetables and the effect of this application on some physical, chemical, sensory and microbial changes occurring in the products during the storage period has been presented.

Bu çalışmada makarnalık buğday çeşitlerinde (Levante, Zenit, Yelken 2000, Dumlupınar, Eminbey, Altın, Ç-1252, ve Kızıltan-91) azot dozlarının verim ve kalite özelliklerine etkisi incelenmiştir. Araştırma 2010–2012 yetiştirme sezonunda Isparta ekolojik koşullarında 0, 5, 10 ve 15 kg/da N dozları kullanılarak yürütülmüştür. Çalışma tesadüf blokları deneme deseninde, faktöriyel düzenlemede üç tekerrürlü yürütülmüştür. Fosforun tamamı (6 kg/da P2O5) ve azotun yarısı ekimle birlikte, azotun diğer yarısı kardeşlenme döneminde verilmiştir. İki yılık araştırma sonucunda, azot dozlarının incelenen tüm özelliklere (m2’de başak sayısı, tane verimi, 1000 tane ağırlığı, hektolitre ağırlığı, camsılık ve protein oranı) önemli etkisinin olduğu belirlenmiştir. Ancak azotlu gübrelemenin etkisi çeşitlere göre önemli farklılık göstermiştir. Genel olarak azot miktarının 10 kg/da üzerine çıkarılması, 1000 tane ağırlığı hariç diğer özelliklerde istatistiksel olarak önemli bir artış meydana getirmemiştir. Sonuç olarak, tane verimi ve kalite özellikleri dikkate alındığında, 10 kg/da N dozu ve Çeşit-1252, Altın, Kızıltan-91 ve Dumlupınar çeşitlerinin Isparta koşullarında yetiştiriciliği tavsiye edilebilir.
