Başpınar Village is a rural settlement in Kemaliye town of Erzincan province located in the East Anatolian Region of Turkey. The history of the village dates back to the 18th century. The traditional fabric of the houses comprises of stone masonry terraced constructions with three to four floors. Başpınar sits on a sloping geography; hence the buildings of the settlement are designed to harmonize with the regional topography. The masonry houses in Başpınar are quite different in terms of plan typology, facade design and construction techniques from those of Kemaliye town, located 38 km away from the village. The findings of the study are based on the evaluation of data collected from a field work of 25 days in July 2012. The fabric of the houses was physically analysed in terms of number of floors, building’s use, building period, construction system and materials, authenticity and preservation state. 216 building inventory cards have been prepared to identify structural problems through external observation. The purpose of this investigation is to examine the main problems of Başpınar’s masonry architectural fabric which are user’s faults, unqualified restorations and deserted buildings. Moreover, some houses were divided into two or three independent houses because of ownership problems. Başpınar houses, which are not registered in national cultural heritage inventory list except the Başpınar Mosque, feature outstanding cultural landscape characteristics. First of all, the authentic masonry fabric of the settlement should be entirely preserved in a legal sense to solve the conservation problems. Furthermore, as part of sustainable conservation efforts, residents of the houses should avoid any interventions that may destroy the architectural authenticity of the houses, raising awareness on the use of available local materials and techniques. © 2016 Taylor & Francis Group, London.

Hybrid magnetic nanoparticles composed from C60 fullerene and γ-Fe2O3 were synthesized by hydrothermal method. XRD, FT-IR, VSM, SEM, and HR-TEM were employed for characterizations. The magnetic saturation value of C60-γ-Fe2O3 magnetic nanoparticles was 66.5 emu g-1. Concentration of Fe in nanoparticles asdetermined by ICP-OES was 40.7% Fe. Particle size of C60-γ-Fe2O3 magnetic nanoparticles was smaller than 10 nm. Maximum adsorption capacity of C60-γ-Fe2O3 for flurbiprofen, a non-steroidal anti-inflammatory drug, was calculated from Langmuir isotherm as 142.9 mg g-1. © Copyright 2014 Informa Healthcare USA, Inc.

The aim of this study was to evaluate Genotype×Environment Interaction (GEI) of chlorophyll meter readings (SPAD) of ten durum wheat cultivars, using data obtained from multi-environment trials during two years, at eight locations. Stability and genotypic superiority for SPAD reading was identified using ANOVA and GGE biplot analysis. Furthermore, the interrelationships among SPAD reading and other yield components and cultivars-by-traits, environment-by-traits, and cultivars-by-environment were studied using scatter, ranking, and comparison of biplot techniques. Substantial variations were found among SPAD reading, yield components, and quality criteria as related to each other, environment, and cultivars. There were positive correlations among SPAD reading with GY, some quality criteria [Protein Content (PC); Wet Gluten (WG), Vitreous Kernels (VIT)], and yield components [stalks m-2 (SS); ear m-2 (ES); Plant Height (PH), Length of Spike (LS)], while Maturation Time (MT) had negative correlation with SPAD. Also, there was relationship among SPAD and SC (Semolina Color) and SDS (Mini Sedimentation) with obtuse angles (< 900), but the correlation was not significant. The GGE biplot indicated that Kızıltepe environment (E6) and Eyyubi cultivar (G3) were the best in terms of SPAD reading. The GGE biplot provided useful information for experimentation of SPAD readings of cultivars when grown under multienvironment. Moreover, SPAD should be considered as the preferred tool, when the breeder is looking for the best and useful tool to determine flag leaf chlorophyll content. © 2015, Tarbiat Modares University.

In this research, a procedure for the preconcentration of Bi at trace levels in milk samples prior to inductively coupled plasma optical emission spectrometry (ICP-OES) is proposed. It is based on the batch magnetic solid phase extraction of Bi ions by fullerene C60 modified maghemite (γ-Fe2O3 superparamagnetic iron oxide nanoparticles-SPION) nanoparticles. The various factors that influence the preconcentration of Bi such as pH, the amount of magnetic nanoparticles, initial Bi concentration, sample volume and the effects of possible interfering ions were investigated. A linear analytical curve was achieved in the concentration range of 0.25-10 ng mL-1 with a limit of detection of 0.06 ng mL-1. The precision expressed as a RSD was 7.5% for a concentration of 0.25 ng mL-1. The method was validated by the analysis of a standard reference material (NIST SRM 1643e). In addition, 96.6-98.7% recoveries were achieved for the spiked samples. Bi concentrations in ten milk samples were successfully determined after the developed method was applied. Bi content in the milk samples ranged from 6.5 to 14.3 ng mL-1. © 2015 The Royal Society of Chemistry.

Background: Cancer is an unnatural type of tissue growth in which the cells exhibit unrestrained division, leading to a progressive increase in the number of dividing cells. It is now the second largest cause of death in the world. The present study concerned antioxidant, anticancer and anticholinesterase activities and protocatechuic, catechin, caffeic acid, syringic acid, p-coumaric acid and o-coumaric concentrations in methanol extracts of flowers, fruits and seeds of Hypericum amblysepalum. Materials and Methods: Antioxidant properties including free radical scavenging activity and reducing power, and amounts of total phenolic compounds were evaluated using different tests. Protocatechuic, catechin, caffeic acid, syringic acid, p-coumaric acid and o-coumaric concentrations in extracts were determined by HPLC. Cytotoxic effects were determined using the MTT test with human cervix cancer (HeLa) and rat kidney epithelium cell (NRK-52E) lines. Acetyl and butyrylcholinesterase inhibitory activities were measured by by Ellman method. Results: Total phenolic content of H. amblysepalum seeds was found to be higher than in fruit and flower extracts. DPPH free radical scavenging activity of the obtained extracts gave satisfactory results versus butylated hydroxyanisole and butylated hydroxytoluene as controls. Reducing power activity was linearly proportional to the studied concentration range: 10-500 μg/mL LC50 values for H. amblysepalum seeds were 11.7 and 2.86 respectively for HeLa and NRK-52E cell lines. Butyryl-cholinesterase inhibitory activity was 76.9 ± 0.41 for seed extract and higher than with other extracts. Conclusions: The present results suggested that H. amblysepalum could be a potential candidate anti-cancer drug for the treatment of human cervical cancer, and good source of natural antioxidants.

In recent years, magnetic nanoparticles attained special interest in nanobiotechnology and nanomedicine due to their uniqe properties and biocompatibilities. From this perspective, hybride nanostructure composed from γ-Fe2O3 magnetic nanoparticle and carboxylated multi walled carbon nanotube was synthesized and characterized by FT-IR, VSM, SEM, HR-TEM and ICP-OES. Microscopy images showed that magnetic nanoparticles were nearly spherical structure that arranged on the axis of carboxylated MWCNT. Particle size was found lower than 10 nm. VSM results showed that the obtained magnetic nanoparticles presented superparamagnetic properties at room temperature. The magnetic saturation value was determined as 35.2 emu/g. It was used for the adsorption and controlled release of harmane, a potent tremor-producing neurotoxin. Maximum adsorption capacity was calculated as 151.5 mg/g from Langmuir isotherm. Concentration of harmane was determined by HPLC with fluorescence detection. The antimicrobial activity of synthesized magnetic nanoparticle was investigated against gram-negative and gram-positive bacteria. However, no activity was observed. © 2015 Elsevier B.V.

The aim of the study was to evaluate hypertension and obesity in students of primary schools in Mardin. Material and Method: This descriptive study was performed with three different schools were selected on the basis of differing socio-economic and cultural classifications were determined 3460 students in Mardin. Obese students were determined by WHO criteria and blood pressures were determined by American Academy of Pediatrics criteria. These values were calculated with the SPSS statistical program. Chi-square test was used for analysis. P <0.05 was considered statistically significant. Results: 10.57 % of the students were obese and 15.78 % of them were overweight. The prevalence of obesity according to gender was 9.05 % for girls and 11.97 % for boys (p<0.01). 1.30 % of the students had presistolic hypertension, 2.02 % of them had sistolic hypertension, 2.65 % of the students prediastolic hypertension and 2.74 % of them had diastolic hypertension. Having hypertension in first degree parents were not found as associated factors with them and their chidren'. More than 2 hours per day TV beholders were obese (x2=4.916; p=0.03). Discussion: Evaluation of hypertension and obesity is necessary in terms of school health. For this reason these two subjects must take place in inspections of school aged children and also educations about obesity and hypertension are given to both students and their families.

Although Agamben defines the camp (concentration or refugees camp) as the paradigm of the state of exception, this statement overlooks not only the physical and spatial conditions of the camp, but also everyday practices that take place inside. Analyzing the spatial practices in current refugee camps in Turkey, the text shows that its design often forgets the very humanity of the refugee. © 2016, Pontificia Universidad Catolica de Chile.

Review of Economics of the Household | Year: 2012

Complete markets imply the separation of food production and consumption decisions such that they can be modeled to occur sequentially and can be studied independently. Separation is very often assumed implicitly in empirical studies of food demand. If there is such separation, then food sourced within the household should not have any influence upon the budget share of each food group. Using this insight, this paper first develops a procedure to test for the separation of household food production and consumption decisions. Furthermore, it incorporates the testing procedure into the Almost Ideal Demand Systems model and utilizes survey data from 2003 for Turkey for empirical testing. It concludes that the separation assumption is unwarranted for Turkey. Next, it investigates the extent of bias in elasticity estimates when the separation assumption is unwarranted. It concludes that ignoring the nonseparation of consumption and production decisions in rural areas leads to significant overestimation of food expenditure elasticity for dairy products and eggs and own-price elasticity for bread and cereals. © 2011 Springer Science+Business Media, LLC.
