    Küresel iklim değişikliğinin sonucu ortaya çıkacak olumsuz yönlerinden etkilenecek ülkeler arasında Türkiye de yer almaktadır. Bu nedenle su stresine tolerant pamuk genotiplerinin geliştirilmesi gelecekte pamuk üretiminin devamlılığı açısından önemlidir. Bu çalışmada yurt dışından ve Nazilli Pamuk Araştırma İstasyonu Müdürlüğü' nün genetik stoklarından sağlanan 48 adet pamuk genotipi materyal olarak kullanılmıştır. Bu çalışma, pamuk genotiplerinin su stresine karşı tepkilerini belirlemek ve su stresine dayanıklı/tolerant pamuk genotiplerini belirlemek amacıyla yapılmıştır. Denemeler Adnan Menderes Üniversitesi Ziraat Fakültesi ve Özaltın Tarım İşletmeleri Sanayi ve Ticaret Anonim Şirketi-Koçarlı deneme alanlarında olmak üzere iki lokasyonda tam (% 100) ve kısıntılı (% 50) sulama koşullarında damla sulama sistemi kullanılarak Augmented deneme deseninde dört tekerrürlü olarak yürütülmüştür. Kısıntılı sulama uygulamasının tüm pamuk genotiplerinde ortalama kütlü pamuk verimi, 1. ve 2. pozisyon koza tutma oranı, bitkide koza sayısı, lif uzunluğu, lif yeknesaklığı ve lif dayanıklılık değerlerini düşürdüğü, çırçır randımanı ve lif incelik değerlerini artırdığı, koza kütlü ağırlığı, lif esnekliği ve 100 tohum ağırlık değerlerini ise etkilemediği gözlenmiştir. Çalışmada yer alan pamuk genotiplerinin kütlü pamuk verimi, sulama suyu kullanım etkinliği ve kuraklık hassasiyet indeks değerleri bakımından birlikte değerlendirildiğinde; CABU/CS2-1-83, Coker 208, TKY 9409, TKY 9304, Semu SS/G, Nazilli 84-S ve Taşkent 1 genotiplerinin kuraklığa hassas, Lachata, MS-30/1, NGF-63, NP EGE 2009, Eva, NIAB 111 ve NIAB 999 genotiplerinin ise kuraklığa tolerant oldukları dolayısıyla su stresine tolerant yeni pamuk çeşitlerinin geliştirilmesinde ebeveyn olarak kullanılabileceği sonucuna varılmıştır.Turkey is among the countries that will be negatively affected by global climate change in the future. Therefore it is important to improve drought tolerant cotton varieties in terms of continuousness of cotton production in the future. In this study 48 cotton genotypes which were obtained from foreign countries and Nazilli Cotton Research Station were used as research materials. The purpose of the study was to determine the response of cotton genotypes to water stress and to select water stress resistance/tolerant cotton genotypes. The study was conducted under two locations; Adnan Menderes University Agriculture Faculty and Özaltın Agriculture Company Experiment Fields. The cotton genotypes were grown under full (100 %) and deficit (50%) irrigation. The experiment design was Augmented design with four replications. Water deficit decreased mean seed cotton yield, 1. and 2. Position boll retention rate, boll number, fiber length, uniformity index, and fiber strength, increased mean lint percentage and fiber fineness, and did not affect boll weight, elongation and seed weight. The result of this study showed that based on seed cotton yield, the irrigation water use efficiency and drought susceptibility index, CABU/CS2-1-83, Coker 208, TKY 9409, TKY 9304, Semu SS/G, Nazilli 84-S and Taşkent 1 genotypes would be drought sensitive, Lachata, MS-30/1, NGF-63, NP EGE 2009, Eva, NIAB 111 ve NIAB 999 genotypes would be drought tolerant and would be used as a parent in the breeding program to improve drought tolerant cotton genotypes

    Differentiated somatic cells can be reprogrammed into induced pluripotent stem cells (iPS cells) by introducingspecific transcription factors. This technique avoids immune rejection and ethical problems in stem cell research.A great revolution in the fi eld of science. As with embryonic stem cells (ES cells), iPS cells are able to self-renewand maintain undiff erentiated state. In vitro, iPS cells can be induced to diff erentiate into a variety of mature cells,therefore, iPS cells in theoretical research and clinical applications are extremely valuable. IPS cell diff erentiationand transplantation in the treatment of blood diseases have a great use, iPS cells can treat nervous system diseases,to provide in vitro disease model, to study the mechanism of disease formation, screening new drugs and thedevelopment of new to provide a new treatment The The use of iPS cells as a nuclear donor cell, with the appropriatereceptor cells after fusion can be directly obtained transgenic animals. Not only can improve the genetic nature ofanimals, but also can break the boundaries of species and get the new animal traits that cannot achieve by usingtraditional mating methods. The research of iPS cells has been widely concerned, and it is the research hotspot in cellbiology and molecular biology. In this paper, the defi nition of iPS cells, the acquisition of iPS cells, the history ofdevelopment, the signifi cance of research, the progress of research, the application of iPS cells, and the problems ofiPS cells were reviewed

    從事戰略文化研究的學者相信,戰略除了是一個現實政治的課題,也是一 個文化的課題。二千多年來,戰略深深地植根於人類的文化傳統中,受到意識 形態、價值體系等種種文化要素的薰陶,而其本身也變成了文化傳統的一部分。 基於戰略行為受到文化要素的影響,戰略取向亦早已成為文化傳統的一部分, 戰略決策不可能完全理性,祇能在特定的文化背景被認為理性。對於某個民族 來說是完全理性的行為,對於具有不同文明背景的對手來說可能是愚不可及, 或完全無法理解的瘋狂行為。不同文明的接觸激化戰略思維中價值體系的互動, 也成為戰略文化硏究的理想素材。冷戰時期成為戰略文化研究的溫床,學者相 信美國和蘇聯的戰略取向都各自受到本身文化價值所影響,形成鮮明對比。例 如蘇聯的戰爭方式偏好於先制攻擊|而美國在運用武力時則懷有十字軍的情意 結。至於中國的戰略文化,則被形容為政治對武力的維制,企圈以盡量微量的 軍事力量解決衝突。近十年來,學者在歷史上找到更多素材加以研究,尤其是 分析不同文明和價值體系接觸的時候產生具爭議性,或看似非理性的行徑,運 用戰略文化角度來觀察較能凸顯歷史和文化的特質。至於研究的角度也深化到 討論不同文化對暴力的不同制約,社會規範對軍事力量的模塑,和意識形態對 戰略取向的界定等問題

    Internet of Things (IoT) is a concept that aims to expand the benefits of connected internet connectivity. Internet of Things (IoT) refers to objects that are uniquely identified as virtual reservations in an internet-based structure. At this time, the limitation of surveillance control in observing objects as negligence of the limitation of view, light conditions or obstructions becomes a problem in application and monitoring. The use of radar is one solution to overcome this condition. Radar stands for radio detection and range is a device whose function is to determine the distance, direction, or speed of a moving and fixed object. Radar can be used in mapping applications and exploration of objects in unknown space. The use of radar can also help navigate moving objects. In this study, a radar prototype with ultrasonic sensors and a simcard module was made that can provide notification via SMS if an object is near the radar. It is hoped that this radar prototype can be used to identify the location of the presence of obstructive objects in rooms with limited access or in dangerous area

    Social Media is now very commonly used for the benefit of society. People mostly use social media to convey information, give opinions, even for media to express themselves. One of the social media that is widely used to convey this information is Twitter. From the use of Twitter, a public opinion tweet emerged about a mobile phone product. The more that is posted on Twitter about cellphones, the more public opinion will arise about cellphone brands. From these opinions, a classification is needed that can distinguish Neutral, Negative, or Positive Opinions. Sentiment analysis or opinion mining is one part of text mining that can help with these problems. In connection with the above, an application is designed that can analyze sentiment analysis from Twitter using the Naïve Bayes classification method. The results of the application of the Naïve Bayes classification method will result in a classification of sentiments into neutral, negative, or positive opinion

    AbstractWe propose an approximate proximal algorithm for solving generalized variational inequalities in Hilbert space. Extension to Bregman-function-based approximate proximal algorithm is also discussed. Weak convergence of these two algorithms are established under the paramonotonicity and pseudomonotonicity assumptions of the operators
