This study evaluates the toxicological and biochemical response of two-spotted spider mites to clofentezine selection pressure. The mortality rate of Tetranychus urticae in adult females depends on increased clofentezine concentration and clofentezine was found to be effective against females. The resistance rate of the CUM strain selected 12 times once per generation with clofentezine was increased from 1.28- to 105.27-fold. The interaction of some synergists with clofentezine was analyzed in the clofentezine-resistant CLOF 12 strain. Synergists had no effect on clofentezine toxicity. The clofentezine-resistant CLOF 12 strain showed resistance against chlorpyrifos, abamectin, propargite, fenpyroximate and amitraz. The modes of inheritance of resistance to clofentezine were found to be incompletely dominant and not sex-linked. Esterase enzyme activity was detected both by gel electrophoresis and microplate reader methods, while glutathione S-transferase （GST） and monooxygenase （P450） activity were detected only by the microplate reader method. During the selection period the esterase, the GST and the P450 enzymes activities were raised from 7.69, 7.09 and 0.003 3 to 18.40, 13.11 and 0.003 7 milli-optical density/rain/rag proteins, respectively. An increase was observed in the band intensity of esterases and esterase enzymes may play a role in clofentezine resistance in T. urticae.

Objective: To investigate the antimicrobial susceptibility of 97 clinical Staphylococcus aureus(S. aureus) strains against 14 antimicrobials and corresponding resistance ***: The antimicrobial susceptibility of the isolates was determined using a disk diffusion method and antimicrobial resistance genes were screened by polymerase chain reaction. Mutations responsible for ciprofloxacin and rifampicin resistance were investigated by polymerase chain reaction and DNA ***: All isolates were found to be susceptible to vancomycin. Various rates of resistance to penicillin(83.5%), ampicillin(77.3%), erythromycin(63.9%), tetracycline(16.5%), amoxicillin/clavulanic acid(16.5%), ciprofloxacin(15.5%), trimethoprim/sulfamethoxazole(15.5%), oxacillin(13.4%), fusidic acid(12.4%), rifampin(6.2%), clindamycin(6.2%), gentamicin(6.2%) and mupirocin(5.2%) were determined. In addition,different combinations of resistance genes were identified among resistant *** resistant isolates had mutations in codon 84(Ser84 Leu) and 106(Gly106 Asp) in the gyr A gene. Mutations in grl A were mostly related to Ser80 Phe substitution. Leu466 Ser mutation in the rpo B gene was detected in all rifampin resistant isolates. All methicillin resistant S. aureus isolates were SCCmec type ***: In conclusion, it was determined that the isolates were resistant to different classes of antimicrobials at varying rates and resistance was mediated by different genetic mechanisms. Therefore, continuous monitoring of resistance in S. aureus strains is necessary to control their resistance for clinically important antimicrobials.

Polycrystalline zinc nitride films are deposited on Coming 7059 glass substrates by pulsed filtered cathodic vacuum arc deposition （PFCVAD）. The crystallographic structure is studied by means of x-ray diffraction. These measurements show that all the films are crystallized in the cubic structure, in a preferred orientation along the （332） and （631） directions. Weak XRD signal shows small crystallites distributed in an amorphous tissue. A small improvement of crystallinity is observed with annealing. Optical parameters such as absorption, energy band gap, Urbach tail, extinction coefficients have been determined. The Urbach tail energy is decreased with annealing at 500℃ for one hour. Energy band gap values are found to be increased by annealing.

We evaluated,for the first time in Turkey,the productivity of a feller buncher during clear-cut operations of two Brutian pine stands located in Canakkale,northwestern Turkey with different diameter classes and terrain *** the first stand with 24.6 cm average DBH,the feller buncher cut full trees and moved them to *** the second stand with 34.3 cm average DBH,the feller buncher cut trees in two stages due to their larger diameters and the relatively steep and rough terrain conditions of the *** effects of specific stand features,DBH and tree height measurements were assessed through statistical analysis in relation to *** results indicate that the average productivity for the first stand was about 118 m^3h^-1,while it was about 80 m3h-1 in the second *** though tree diameter and volume were higher in the second stand,productivity decreased by32.3%due to extra time spent on the two-stage cutting *** results revealed that harvesting operations should be planned carefully and the right equipment selected by accounting for different tree sizes,terrain conditions and machine specifications in order to better understand their effects on production.

阿拉伯之春的影响下在叙利亚开始的内部动荡和反政权示威在短时间内对叙利亚及其周边国家都产生了深远的影响,并开始了一段不确定的结局。政治的不稳定性和不确定性是当前危机造成的主要问题。这个不稳定的环境令直接参与这一进程的与叙利亚相邻的土耳其面对了许多问题。不仅由于该地区不稳定造成的问题而是由于土耳其-叙利亚由于双边关系的恶化出现的政治,经济和社会等这些问题也带来了负面影响。叙利亚的战争已使数百万叙利亚人在其他国家避难,而土耳其就是其中之一。阿拉伯之春后出现的叙利亚危机给土耳其带来的不稳定性的直接和间接影响导致了土耳其参战。这份研究报告的重点是土耳其作为区域性第三方行动者对叙利亚冲突的干预。这硕士报告的目的是揭示人们对国家安全的看法对土耳其的现有或预期干预有多么决定性,以及这种情况在多大程度上有助于参与冲突的其他行为者的行为和方法。据此,本研究解释了土耳其进行干预的动机,土耳其使用的方法以及土耳其在此过程中与其他第三方参与者的互动。研究结果表明,国家安全现象是土耳其干预的关键因素,土耳其的战略和干预方法已根据其他第三方行为者的行为和冲突的动态而发生了变化。叙利亚内战被定义为最近时期最复杂的州内冲突之一,就其影响和条件而言,是非常引人注目的。这也是至关重要的,因为第三方参与者在冲突过程中具有重大影响。在这一点上,当美国,俄罗斯和伊朗等全球大国和地区大国提高其效率时,就政治或军事,经济和社会而言,这是在冲突过程中直接或间接地实现的;据观察,土耳其也参与了这一问题。更明确地说,虽然复杂的冲突地区通过影响该地区而越过边界,但土耳其更受冲突所造成的条件的影响,并面临与国家安全密切相关的风险。在这种情况下,本研究论文的重点是土耳其,它以第三方角色参与叙利亚冲突。因此,本研究旨在分析土耳其作为叙利亚冲突地区级第三方行动者的干预。进行这硕士报告的主要原因是,揭示对国家安全的看法对土耳其的现有或预期干预有多么决定性,以及这种情况在多大程度上有助于参与冲突的其他行为者的行为和方法。为此,本研究的主要研究问题之一是对土耳其的推动因素是什么?另一个主要研究问题是土耳其首选哪种方法/策略?这项研究分析了土耳其干预的方法和动机因素,还有助于了解参与冲突的其他参与者的直接或间接干预如何对土耳其解决问题的方式产生影响。在这方面,由于土耳其的干预方法会在不断变化的周期和冲突动态的框架内发生变化,因此在冲突生命周期内正在评估土耳其的干预方法。当考虑到文献中有关土耳其对叙利亚的外交政策的许多研究都是描述性的时,本研究旨在通过第三方对土耳其干预叙利亚内战的多方面描述,为文献做出贡献。。在此框架下,土耳其的动机因素包括地区竞争,第三方行为者对该地区的行为,对恐怖组织的安全担忧,土耳其与叙利亚的长期边界,冲突蔓延的危险以及叙利亚难民的处境。可以看出,土耳其在这一过程中采取了政治/外交,军事和经济干预方法。据此,土耳其在整个过程中实施的战略以及经济,政治和军事干预方法已经发生了变化,这与该地区其他第三方行为者的行为以及冲突的动态相一致。就显示冲突的动态和参与者的互动而言,这是至关重要的。因此,即使第三方参与者出于不同的原因和/或兴趣而介入冲突地区,也确实存在着第三方参与者在整个过程中相互影响并受冲突动态影响的事实。
