Emin Atay | Sedat Karaman
This study was conducted to assess the structural and environmental conditions and potential problems of under-cover production systems of Çarşamba town, which constitute about 87,81% of under-cover production potential of Samsun Province through comprehensive literature search and to develop possible solutions towards these problems. Selected facilities were analyzed for their structural characteristics, production techniques, technology use, environmental conditions through surveys, drawings, observations and photographs. Present findings revealed that all of the family type under-cover production systems are composed of individual (single) constructions. Facility owners had quite low level of education and under-cover production systems constituted a significant place in their economic statuses. Under-cover production systems were mostly lack of technology because of financial burdens and unplanned production activities. Ventilation, heating and cooling systems, playing a significant role in control of environmental conditions, were mostly insufficient and relevant design criteria were not mostly taken into consideration. With this study, potential problems were identified, structural and environmental requirements of under-cover production systems were determined, and recommendations were provided to producers accordingly.

Valuation of postharvest loss and identification of its causes enables to develop proper measures required to reduce losses. The study was conducted at “Fogera” District, South Gondar, Ethiopia between 2017 and 2018 years to assess the extent of postharvest loss of tomato (Solanum lycopersicum L.) and to identify major causes with respective handling system. In this study, a total of 125 farmers and 40 traders (10 wholesalers and 30 retailers) were involved as main respondents. Data collection was done using semi structured interview schedule, key informant interview, focus group discussion and observation. Besides respondents estimation, a sample analysis was conducted to estimate the extent of postharvest loss as per the FAO minimum quality standards. Descriptive statistics such as average, percentage, frequency and standard deviation were used to analyse data and tables, graphs and charts were used to present result. Result revealed that almost half of tomato produced is damaged and puts out of normal use with highest loss at producer level due to different causes which are complex and interrelated across tomato market chain. Marketing situation, insect pest and disease, lack of awareness, low economic status of producers, late harvesting, mechanical damage during harvesting and transportation, poor quality of produce and price fall were some of the reasons identified as major cause of post-harvest loss of tomato. For solving the postharvest loss problems, actors in supply chain has to develop cooperation and effective communication among all the research, extension, and industry personnel involved.

Var olduğu günden beri doğa ile etkileşim halinde olan insanoğlu doğadan farklı amaçlar için yararlanmaktadır. Eğlenmek, çeşitli aktivitelerde bulunmak, kendini iyi hissetmek için her zaman doğanın bir parçası olan yeşil alanlara ihtiyaç duyulmaktadır. Ancak insanlar; hızlı ve çarpık şehirleşme, sanayileşme ve teknoloji gibi faaliyetler sebebiyle azalan yeşil alanlarla artan kapalı mekanlarda yaşamlarını devam ettirmektedir. Kırsal alanlarda yaşayan insanların da artan kaygıları, onları şehirlere çekmeye başlamış, kentler giderek yoğunlaşmış, birçok kentte ihtiyacı karşılamak adına betonlar yükselmiş, yaşam kalitesi azalmış, doğa hiç bozulmayacakmış gibi tahrip edilmiş ve bugün birçok konut yeşil alansız, bahçesi olmadan inşa edilmiştir. Yeşile özlem duyan, doğadan uzaklaşan günümüz insanında depresyon ve buna bağlı olarak gelişen psikolojik bozukluklar görülmeye başlanmıştır. Doğa ve doğal alanların insanlar üzerindeki olumlu etkileri birçok bilim insanı tarafından da tespit edilmiştir. Son yıllarda, insan sağlığı üzerinde yapısal çevrenin etkileri dikkat çekmiş ve “iyileştirici bahçe” kavramı ortaya çıkmıştır. İyileştirici bahçeler peyzaj mimarlığı çalışmalarında da yeni bir hareket etkisi oluşturmuştur. Bu çalışmada; iyileştirici bahçelerin çeşitli sağlık problemleri olan hastalar üzerindeki etkilerinden bahsedilerek, tasarım ilkelerine göre değerlendirmesi yapılmıştır.

The main objective of selection studies is to select genotypes with superior properties from hybrid combinations. In this study, seedling and first clonal generation stages were carried out with the variation obtained by using hybrid seeds from three different hybrid potato combinations. The research was carried out in cloth greenhouse (seedling generation) and field (first clonal generation) in Tokat/Kazova conditions between 2017 and 2018. In the study, 5500 hybrid true potato seeds were used from three combinations (A3/15×Bafana, T5/4×Bafana, Başçiflik Beyazı×Lady Olympia) created by using five different parents. These hybrid true potato seed were planted in 13x8 vials and then seedlings were transplanted to appropriate sized pots (15×24 cm) when they reached to 10-15 cm length. The hybrid clones obtained from the seedlings were selected according to the breeder preference and the first clonal generation stage was started with the clones (1380 clones) which were suitable to be continued. The plantings were constructed with 70×50 distance in the field conditions. After harvest, each of the 1380 clones was examined separately and 1100 clones were selected as a result of negative selection made by considering the phenotypic characteristics of the tubers.

The first introduction of human being with milk begins with human milk during infancy, continues with very commonly with cow’s milk and may be with other milk types during lifetime. Cow breeding and utilizing its milk in nutrition is widespread in the world. There are particular species common to their area such as donkey, camel, mare, yak and llama have an important share in milk production in the world. Donkey milk has higher serum protein and lower casein content being similar to human milk so regarded as a good and safer alternative for infants suffering from cow’s milk protein allergy. Mare milk is used as a therapeutic agent for the treatment of some metabolic and allergic illnesses. It is generally consumed as fermented product. Llama milk contains higher amounts of calcium and phosphorus than cow's milk. Camel milk has high vitamin and mineral content and has claimed to have medicinal proteins. Its casein micelle size is larger naturally and it has lower amount of κ-casein these cause difficulties in cheese making and affect curd quality. Reindeer milk is an energy dense food with its high fat and high protein content when compared to cow’s milk. Its high protein content could make it suitable for protein supplementation. Its low lactose content makes its consumption possible by lactose intolerance patients. Yak is richer in almost all main nutritional components when compared with cow’s milk. It can be used in cheese, butter making and dried milk products. The objective of this review was to represent the composition of different animal species’ milks; other than cow, buffalo, sheep and goat, their importance in nutrition and technological use.
