Orhun Soydan | Ahmet Benliay
After realizing that multi-storey buildings are contrary to human nature, the importance of natural landscape and green areas around it has been noticed. For this reason, people want to see how their environment will be in the design phase and the importance of project presentations is increasing day by day. Information technologies for spatial thinking, imagination and modelling have gradually started to be included in landscape design processes. The concept of virtual reality, augmented reality and immersive virtual reality are becoming more and more involved in our lives due to reasons such as the size of the devices getting smaller and their prices being relatively accessible to everyone. As an alternative to traditional presentation techniques and two-dimensional presentation techniques on the computer, making presentations in a virtual reality environment can be a stronger factor in people’s perception of the environment. In the study visual sets in basic, intermediate and advanced level of detail for the same landscape design and project site have been created. Each set consists of hand-drawn perspective image, computer aided perspective image, stereoscopic 360-degree VR image and an augmented reality model. In order to evaluate these visual sets, interviews were made with 10 landscape architects who are experts in the subject. As a result of the study, criteria’s for landscape presentations has been discussed and the advantages and disadvantages of landscape design presentations that will be created using virtual and augmented reality have been evaluated.

Feyza Nur Dursun | Erdinc Bal
In this study, the effect of postharvest salicylic acid (2 mM), oxalic acid (5 mM), putrescine (2 mM) and calcium (4% CaCl2) applications on storage performance of Autumn Giant plum fruit were investigated. After applications, plum fruits were placed in modified atmosphere packaging (MAP) and stored for 40 days at 85-90% relative humidity conditions at 0.5±0.5°C. In order to determine the fruit quality characteristics after treatments, weight loss, soluble solids content, titratable acidity, fruit firmness, ascorbic acid, total flavonoids, total phenolics and total antioxidant content analysis were performed at 10 days’ intervals. According to the results, the effect of applications on weight loss was not significant. The maximum decrease in flesh firmness, titratable acid and ascorbic acid content during storage was determined in control fruits. Although fluctuations in the form of increase or decrease in biochemical compounds were generally observed, decreases occurred according to harvest value at the end of storage period. Considering all measurements and evaluations, it was determined that application of salicylic acid and putrescine had a more positive effect on preservation of fruit quality properties and biochemical content of Autumn Giant plum cultivar during storage than other applications.

In this study, it was aimed to investigate the arterial vascularization of the kidneys in the South Karaman sheep breed. Twelve South Karaman sheep kidneys were used in the study. The course of the renal arteries in the kidney was examined by means of dissection and corrosion cast techniques. The kidneys were vascularized with right renal artery and left renal artery to the arteries originating from the abdominal aorta. Right renal artery was seen to be slightly more prominent than the left renal artery. Left renal artery was measured longer and thicker than the right renal artery. The renal artery entering the renal hilus, dorsal and ventral part of the renal artery were detected. However, in several materials, the left renal artery was shown to have a third branch. The dorsal and ventral branches gave interlobar artery with numbers ranging from 2-5. Each interlobar artery had multiple arcuate artery. These arteries ended by giving the interlobular artery. Anastomosis was not observed between the renal arteries. Although there were some important variations in the distribution of renal arteries of South Karaman sheep, similar findings were reported in the literature.

Muyiwa Adegbenro
In developing nations Nigeria inclusive, most of the cereals grown are for human consumption. Conventional feedstuffs use in livestock production especially in poultry enterprise has intensified the competition for available grains. Consequently, the cost of poultry production is jacked up. Since poultry provides most of the animal protein consumed either in the form of meat or egg, exploring tropical vegetables as a route of escape to reducing the cost of feeding will be a great gain in the poultry enterprise. Tropical vegetables especially the African leafy vegetables (ALVs) are economical and highly nutritive possessing good levels of vitamins, minerals, protein and essential amino acids. The mineral constituent of some tropical vegetables as well as their nutritive impact on the performance, meat quality, egg quality in broiler and laying birds as presented in this review paper. Although, the availability of ALVs all year round, its moisture content level and presence of anti-nutrients may tend to limit its usage in poultry feed, adopting irrigation techniques and improved seedlings as well as exploring the processes of enhancing the nutritional value of ALVs to combat anti-nutrients to tolerable levels by the birds make it possible to be considered as good alternative in poultry diets.
