Ömer Faruk Gamlı | Özge Süfer | Tülin Eker
Olive leaves have been catching consumers’ and researchers’ great interest because of benefits on human health. In this study, the olive leaves were dried by microwave method at different powers (52, 90, 167, 290, 347 W real effective power levels) and drying kinetics of olive leaves were examined to find the best mathematical model. Page model was the most suitable model rather than the others. Diffusion coefficients were ranged between 2.65×10-10 to 6.87×10-10 m2/s and an increment in power level promoted moisture diffusivities. Dried olive leaves were used to get leave tea and different infusion temperatures were investigated to recover the total polyphenols (mg GAE/kg) and radical scavenging activities (%). Rising in infusion temperature, especially at 100°C enhanced the extraction levels of polyphenols from leave tea. Olive leaves dried at 167 W had higher phenolic contents (2282.9 mg GAE/kg) among all samples.

Zuhal Karakayacı
In this study, the factors affecting on land value in urban sprawl were analysed via regression analysis. In the analyse, the nominal value of land was taken to be dependent variable while factors affecting the value of the land in urban sprawl were considered to be independent variables. 9 factors that were thought to affect the value of the land were handled. In this study, 3 separate models were analyzed, and all models provided statistically significant results. The basic reason for applying three separate models is to be witness the effects by including the variables in different categories (environmental, social amenity and economical factors) separately to the model. As a result of these analyses, all of environmental, amenity and economic factors should be considered for valuation of urban sprawl.

Hüsniye Aka Sağlıker | Neslişah Mutlu
Bu çalışmada; Osmaniye’de demir, çelik ve metal sanayi işletmelerinin üç ayrı bölgesinden mesafeye bağlı olarak örneklenmiş toprakları ile bu işletmelerden uzakta bulunan Osmaniye Korkut Ata Üniversitesi kampüs topraklarının bazı iz element [Cu, Mn, Fe ve Zn (mg/kg)] içerikleri ve karbon mineralizasyonu (28°C, 45 gün) karşılaştırmalı olarak incelenmiştir. Karbon mineralizasyonu için CO2 respirasyon yöntemi kullanılmıştır. Tüm topraklarda iz element içeriklerinin sınır değerlerden düşük olduğu belirlenmiştir. Sanayi Tesisleri yakınından örneklenmiş 1 nolu toprağın karbon mineralizasyonu [15,0 mg/C (CO2)/100 g KT] 4 nolu kampüs toprağından [30,0 mg/C(CO2)/100 g KT)] anlamlı düzeyde düşük bulunmuştur. Benzer durum dört toprağın karbon mineralizasyon oranları arasında da gözlenmiş olup Sanayi Bölgesi’nin üç toprağın da yine kampüs toprağından anlamlı düzeyde düşük bulunmuştur. Tüm bu bulgular toprakların karbon mineralizasyonu ve iz elementi içeriklerinin Sanayi Bölgesi’nden uzaklaştıkça değişmediğini; toprakların organik karbon ve azot içerikleri ile pH’larına bağlı olarak değişebileceğini ortaya koymaktadır.
