Impacts on Nomadic Livestock of Strict Nature Protect Efforts: An Example from Isparta-Egirdir Region, Turkey
Hasan Alkan,Mehmet Korkmaz
Journal of Animal and Veterinary Advances , 2012,
Abstract: Many areas were allocated by various lows as protected area for conservation of natural resources in Turkey. However, the practice has caused the benefit loss that happens by reason of the prohibitions and limitations for the local people who are mainly living forest villages. As local people are an important entity of protected area and their activities (e.g., livestock, farming, etc.) are directly concerning conservation of forest and others, it is necessary to give focus on their interaction with the nature. In this study, relations between nomadic livestock and nature conservation efforts were discussed by example of Egirdir Region. Field survey was carried out to collect information in each village using interviews from 2007-2008. According to results of the study nature conservation efforts have caused to benefit loss in term of nomadic livestock in the Egirdir Region as well as Turkey. Besides, villagers haven t been adequately supported in term of alternative livelihood resources, until now. Thus, negative local perceptions have come out concerning protection efforts.

English AbstractThe efforts to promote the entrepreneurship have significant results in the solution of unemployment problem which has been one of the most important economic issues. In this regard, governments have been recently developing various methods to widening entrepreneurship such as entrepreneurial loans, new incentives to start-up’s and business development centres. The model of Business Development Centres ( GEM) as an entrepreneurship promoting mechanism, support both new business establishments that is to say the small and medium sized businesses which are shortly defined as SME’s, and employment increases. In GEM model, at the early stages of business establishments supports are provided to entrepreneurs to assist their institutionalization during the market entrance and development phases. By doing so, it is also aimed to create healthier businesses after graduation from GEM projects. First GEM projects which have been implemented in Turkey have given its first results: many businesses have started and some have graduated from GEMs and take place in the related sectors. This study by analyzing the implemented GEM model in Turkey, examines existing GEMs and their positive impact on employment.
A molecular phylogeny of the Cephinae (Hymenoptera, Cephidae) based on mtDNA COI gene: a test of traditional classification

ZooKeys , 2011, DOI: 10.3897/zookeys.130.1466
Abstract: Cephinae is traditionally divided into three tribes and about 24 genera based on morphology and host utilization. There has been no study testing the monophyly of taxa under a strict phylogenetic criterion. A molecular phylogeny of Cephinae based on a total of 68 sequences of mtDNA COI gene, representing seven genera of Cephinae, is reconstructed to test the traditional limits and relationships of taxa. Monophyly of the traditional tribes is not supported. Monophyly of the genera are largely supported except for Pachycephus. A few host shift events are suggested based on phylogenetic relationships among taxa. These results indicate that a more robust phylogeny is required for a more plausible conclusion. We also report two species of Cephus for the first time from Turkey.
An Investigation of the Behaviour of Steel Frames with Masonry Infills under Lateral Loading
M. Yasar Kaltakci,Hasan Husnu Korkmaz,Ali Koken
Journal of Engineering and Applied Sciences , 2012,
Abstract: Frame systems are commonly used in structural design. In the design and analysis of these types of structures, beams and columns are essential. Since no practical and generally recognized method has yet been developed, non-structural components such as, architectural walls are not usually taken into consideration in the analyses. On the other hand, the real structure may exhibit a different behavior than that of bare frames under lateral loadings such as earthquakes. This study describes the use of finite element method to asses the contribution of the infill to the behaviour of infilled steel frames. The influence of masonry infills on the behaviour of steel frames is studied experimentally and analytically by using a finite element model to simulate the behaviour of infilled steel frames subject to lateral loads. New material models are proposed for masonry infill (no plaster) and plastered masonry infills. The model is verified by comparison with laterally tested infilled frames. The validity of results is checked with the experimental results. Steel framing is chosen, due to fact that its mechanical behaviour is rather well known with respected to reinforced concrete structure. Besides the fully infilled steel frames, partially infilled frames are also tested and analyzed. The infill is modeled with, well-known, diagonal strut analogy also with shell elements. A new modeling proposal, with the use of nonlinear springs is also introduced in the study. The proposed analyze method is based on adjustment or calibration of Young Modulus of infill frame material. At the results, experimental lateral load vs deflection curves are compared with analytical ones.

Indian Pacing and Electrophysiology Journal , 2009,
Abstract: We aimed to investigate the effects of nebivolol and quinapril treatments on P-wave duration and dispersion in hypertensive patients. Hypertensive patients who were in sinus rhythm were assigned to the two treatment groups and received either 20 mg quinapril/day or 5 mg nebivolol/day. P-Wave dispersion (PWD) was measured at baseline and after four weeks of treatment and defined as the difference between the maximum (Pmax) and the minimum (Pmin) P-wave duration. The study group consisted of 54 patients (Mean age: 53 ± 9 years, 46% women) with 27 patients in each group. At 4-week follow up both treatment groups showed a significant reduction (p<0.001) in systolic (SBP) and diastolic blood pressure (DBP). Heart rate (HR) reduction was significant in patients receiving nebivolol (P=0.001). Both groups showed a similar (P=0.413 for PWD, p=0.651 for Pmax) but significant reduction in PWD (nebivolol: -16±14, P<0.0001 and quinapril: -13±11, P<0.0001) and Pmax (nebivolol: -10±11, P=0.001 and quinapril: -9±11, P=0.001). A 2 (Time) x 2 (Group) mixed-model repeated-measures analysis of variance revealed that the main effect of Time was significant for Pmax (P=0.002) and PWD (P=0.008) after controlling for changes in SBP, DBP and HR. However, the main effect of Group and Time x Group interaction was not significant for both variables (All p values >0.05). In conclusion, short-term treatment with nebivolol and quinapril produces a similar but significant reduction in Pmax and PWD in hypertensive patients. This effect is independent of blood pressure and heart rate changes.

Abstract: Objective: We aimed to investigate the relation of brachial artery intima-media thickness (IMT) with endothelial function and left ventricular mass (LVM). Methods: Fifty four stage I-II hypertensive patients according to JNC VII who were not taking any medication and 27 age and sex-matched healthy controls were included to this cross-sectional observational study. IMT was measured by the same radiologist who was unaware of the patient’s clinical status by using high resolution ultrasound machine. Endothelial function was evaluated by flow mediated dilation (endothelium-dependent vasodilatation, FMD). LVM was calculated by using Devereux method. LVM index (LVMI) was obtained by dividing LVM to body surface area. Mann-Whitney U test was used to compare continuous variables, qualitative variables were compared by Chi-square test and the relations of parameters were evaluated by multiple linear regression analysis. Results: Both groups (hypertensive and control) were similar with respect to age, sex, left ventricular ejection fraction. IMT was significantly higher in hypertensive group (0.43±0.09 vs 0.33±0.06 mm; p<0.001). FMD values were also significantly different between hypertensive and control groups (4±4% vs 13±12%; p<0.001). LVMI was significantly different between hypertensive and control groups LVMI (124 ± 5 vs 99±6 gr/m2, p=0.002). The correlation between IMT and FMD (r=0.260; p=0.026) and IMT and LVMI (r =0.348; p=0.004) were statistically significant. A correlation was found between IMT and LVMI independently of other variables (beta=105; p=0.004) when LVMI was accepted as dependent variable in multivariate linear regression analysis (R2=0.570, p<0.001). According to this finding, the 105 units increase in LVMI occurs when IMT increases by 1 mm. Conclusion: Brachial artery IMT is related to endothelial function and LVM. According to these data, any negative changes of the IMT may reflect the similar negative changes in other parameters.

Mediators of Inflammation , 2007, DOI: 10.1155/2007/89649
Abstract: Background/Aim. Coronary artery ectasia (CAE) was thought of as a variant of atherosclerosis. C-reactive protein (CRP) which is among the most sensitive markers of systemic inflammation, and elevation of systemic and local levels of this inflammatory marker which has been associated with an increased risk for cardiovascular disease in the obstructive coronary artery disease (O-CAD) are well known, but little was known in CAE. The anti-inflammatory effects of statins and the effect of angiotensin-converting enzyme (ACE) inhibitors on endothelial dysfunction are well established in atherosclerosis. The aim of the present study was to investigate CRP level and its response to statin and ACE inhibitor treatment in CAE. Materials and method. We measured serum hs-CRP level in 40 CAE (26 males, mean age: 56.32±9 years) and 41 O-CAD (34 males, mean age: 57.19±10 years) patients referred for elective coronary angiography at baseline and after 3-month statin and ACE inhibitor treatment. Results. Plasma hs-CRP levels were significantly higher in CAE group than O-CAD group at baseline (2.68±66 mg/L versus 1,64±64, resp., P<.0001). Plasma hs-CRP levels significantly decreased from baseline 3 months later in the CE (from 2.68±0.66 mg/L to 1.2±0.53 mg/L, P<.0001) as well as in the O-CAD group (from 1.64±0.64 mg/L to 1.01±0.56 mg/L, P<.001). Conclusion. We think that hs-CRP measurement may be a good prognostic value in CAE patients as in stenotic ones. Further placebo-controlled studies are needed to evaluate the clinical significance of this decrease in hs-CRP.

Klimik Journal , 2011,
Abstract: Cat-scratch disease (CSD) is an infection caused by Bartonella henselae and is characterized by a chronic inflammation of the lymph nodes. A 34 year-old female patient presented to the General Surgery Clinic with the complaint of swelling in the supraclavicular area which had been present for the previous 2 months. A mass of approximately 3x1 cm in diameter was observed in the supraclavicular area during her physical examination. An excisional biopsy was performed and the histopathological examination revealed marked follicles in the germinal centers, some of which had granuloma structures consisting of histiocytic cells together with polymorphonuclear leucocytes and necrosis in their centers. This appearance was at first considered as consistent with CSD. In her medical history, it was learnt that the left hand of the patient had been scratched by a cat 2.5 months earlier. The patient was given azithromycin for 5 days. CSD should be considered in the differential diagnosis of lymphadenopathy for cases who have had previous contact with cats.

Mediators of Inflammation , 2012, DOI: 10.1155/2012/606207
Abstract: Objectives. There are limited clinical data revealing the relationship between mitral annular calcification (MAC) and systemic inflammation. The goal of the present study was to compare high-sensitivity C-reactive protein (hs-CRP) levels in patients with and without MAC and investigate the relationship between MAC and hs-CRP. Methods. One hundred patients with MAC who underwent transthoracic echocardiography (TTE) and 100 age-matched controls without MAC who underwent TTE were included in our study. Hs-CRP levels were compared between groups. Results. Prevalence of female gender, hypertension, and coronary artery disease were significantly higher in the MAC group than in the control group (64% versus 45%, =0.007, 42% versus 28%, =0.03 and 37% versus 18%, =0.003, resp.). On multivariate analysis, age, gender, and coronary artery disease were the only independent predictors of MAC. The levels of hs-CRP were higher in the MAC group than in the control group (2.02±0.35 versus 1.43±0.47 mg/dl, <0.001). This increase in hs-CRP levels in the MAC group persisted in patients without hypertension, coronary artery disease, and in male patients when compared to the control group. Conclusions. Our study demonstrated that hs-CRP, which is a sensitive marker of systemic inflammation, increased in patients with MAC.
