Hibiscus sabdariffa L. (Hibiskus) is a plant that belongs to the Malvaceae family and and is a rich source of anthocyanins and other bioactive compounds. In this study, the total phenolic and flavonoid content, antioxidant and antimicrobial activities of commercially supplied Hibiscus sabdariffa calyx extracts obtained by two different extractors (soxhlete and ultrasonic bath) were investigated. In addition, fatty acids were analysed by GC-MS analysis, 14 different fatty acids were determined and the major fatty acid components of extracts obtained from plant calyxes were palmitic acid (15.25%) and oleic acid (32.18%) and linoleic acid (30.77%). The ultrasonic bath was found to be more effective to reveal the bioactive contents of the extracts than the soxhlete. Total phenolic content and flavonoid values of plant calyx extracts (USB) were 23.29 and 3.08 mg ml-1, respectively, and FRAP and IC50 (% DPPH) values were 47.54 µg g-1 and 0.61 mg ml-1, respectively. Antimicrobial activity experiment carried out with total of 9 microorganisms consisting of seven bacteria and two yeast showed that H. sabdariffa extracts had dose-depended inhibition on test microorganisms but S. cerevisia.

Iron (Fe) is an important trace mineral for plant development, and plants grown in Fe deficiency experience yield losses due to the leaf chlorosis. In addition to agronomic measures that can be taken to minimize these losses, new plant genotypes can be developed effectively through genetic engineering. While dicots such as Arabidopsis thaliana use a reduction-based strategy to uptake high amounts of iron from the rhizosphere, the chelation strategy has evolved in Gramineous plants including barley (Hordeum vulgare). In this study, barley NICOTIANAMINE SYNTHASE1 (HvNAS1) gene, which is responsible for the production of nicotianamine that can complex with iron, was cloned and expressed at a constitutive high level in Arabidopsis plants. The expression levels of Arabidopsis genes encoding for the proteins involved in iron uptake increased together with HvNAS1 in the T3 Arabidopsis plants. Moreover, the root lengths, root and stem fresh weights, ferric chelate reductase enzyme activities of the plants also increased in the transgenic Arabidopsis plants under Fe deficiency. In addition, significant increases in iron and zinc levels were determined in the roots and shoots of transgenic Arabidopsis plants. As a result, transgenic Arabidopsis plants overexpressing the barley HvNAS1 gene can take up more iron from the rhizosphere and carry this iron to the shoots. This study demonstrates the power of genetic engineering to develop Arabidopsis plants overexpressing the HvNAS1 gene and therefore tolerate iron deficiency.

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.

Traditional foods, which are the special products that have emerged with the experience of many years, reflect the culture, identity, characteristics and heritage of a region and help the development and continuity of these regions by preventing migration from rural areas. In terms of revealing the cultural richness of societies, the place of traditional foods in social life is very important. Traditional foods have an important place in the nutrition of the people living in the region and constitute the specific taste of the region. One of the cultural riches traditional desserts are produced and consumed in various regions of Anatolia. The desserts, which have been produced for centuries from past to present, have always had an important place in our culture. Traditional desserts have a rich variety both as milky and sherbet dessert in terms of the material added and the production technology. Nevzine Dessert, which has been produced for centuries, is a traditional sherbet dessert variety prepared by using tahini, molasses and walnuts of Kayseri province. The use of sugar and grape molasses in the sherbet is a feature that distinguishes this dessert from other syruped desserts. Nevzine Dessert is served on religious holidays and its energy is quite high.The aim of this study is to give information about Kayseri’s traditional Nevzine Dessert, its components, preparation and cooking based on the interviews and researches with the locals.

The African giant rat (Cricetomys gambianus, Waterhouse) is a wild rodent in sub-Saharan Africa widely hunted as popular meat delicacy. Domestication of this rat has been poor, probably due to nutrition among other factors. Developmental studies of the duodenum, jejunum and ileum as well as investigations of diet-based structural modifications of the small intestine were carried out in the rats using neonates, juveniles and adults with the aim of providing useful research information which could lead to improved domestication. The mean body weights of the animals were 39.67±1.45 g, 225.00±25.00 g and 742.90±62.13 g, respectively for the neonate, juvenile and adult rats. Significant differences were also observed in the villus height, villus width and crypt depth between the neonates and juveniles, unlike between juvenile and adult rats. These changes in intestinal morphology between the neonate and juvenile rats could be a measure of the neonates’ adaptation to shifts from digestion of maternal milk to the consumption of solid and semisolid forages. Respectively for neonates, juvenile and adult rats, 188%, 228% and 30% increases in villus height for the duodenum, jejunum and ileum respectively, were observed. This is suggestive of larger surface area of the small intestine for digestion and absorption. This study elucidates the structural modifications of the small intestine which can be applied to dietary modifications in response to age in an effort to achieve a more successful domestication of the animal.

Organic matter (OM) content of the soils should be improved for sustainable productions. Municipal solid waste compost (MSWC) is an organic material used in several countries to improve soil OM contents. This study was conducted to determine potential use of MSWC as soil amendment. Field experiments were conducted for two years with single MSWC treatments. Experiments were conducted on 18 plots in randomized complete blocks design with 3 replications. Six different MSWC doses (0, 40, 80, 120, 160 and 200 t ha-1) were applied to experimental plots. Compost doses were calculated in dry weight basis, applied to 21 m2 plots and sunflower was sown as the experimental plant of the study. Following the sunflower harvest, disturbed and undisturbed soil samples were taken from the experimental plots and soil samples were subjected to various analyses. Applied MSWC doses significantly increased soil OM contents, electrical conductivity (EC) and cation exchange capacity (CEC), aggregate stability (AS) and saturated hydraulic conductivity (Ksat) and reduced soil bulk density (BD). Effects of MSWC on soil pH were not found to be significant. Effects of MSWC treatments were more remarkable with increasing doses. MSWC treatments increased soil OM contents about 3 folds and increased CEC by about 25%. MSWC treatments significantly increased salt contents of the soils. Such increases were found to be significant at 1% level in the first year and 5% level in the second year. Increasing OM contents also increase soil aggregation, thus reduced bulk density and increased hydraulic conductivity. Correlation analysis revealed significant correlations between OM and AS. Present findings revealed that MSWC positively influenced physical and chemical characteristics of clay-loam soils of arid and arid climates, but salt contents should carefully be monitored in repetitive uses.
