A 1.2 V and 69 mW 60 GHz Multi-channel Tunable CMOS Receiver Design

A multi-channel receiver operating between 56 GHz and 70 GHz for coverage of different 60 GHz bands worldwide is implemented with a 90 nm Complementary Metal-Oxide Semiconductor (CMOS) process. The receiver containing an LNA, a frequency down-conversion mixer and a variable gain amplifier incorporating a band-pass filter is designed and implemented. This integrated receiver is tested at four channels of centre frequencies 58.3 GHz, 60.5 GHz, 62.6 GHz and 64.8 GHz, employing a frequency plan of an 8 GHz-intermediate frequency (IF). The achieved conversion gain by coarse gain control is between 4.8 dB–54.9 dB. The millimeter-wave receiver circuit is biased with a 1.2V supply voltage. The measured power consumption is 69 mW

The politics of Istanbul's Ottoman heritage in the era of globalism

History is not merely about events which remind of the past, it is also about political struggles in the present. This is particularly so in contemporary cultural markets where 'history' is increasingly produced and disseminated in a host of commercialized forms. This paper focuses on competing 'historical' narratives which circulate across Istanbul's cultural markets, as they mediate between between the past and the ethnographic present of the city. These are 'political' narratives in the sense that they mobilize alternative versions of Istanbul's Ottoman past, from different class locations and address different constituencies

From the morality of living to the morality of sying: hunger strikes in Turkish prisons

Political hunger strikes have been part of the debates on human rights in many countries around the world. This paper explores the preconditions for and motives behind hunger strikes in Turkey by conceiving the hunger strikers as a part of citizenship politics through which strikers not only express their views against certain common issues, but also declare total opposition to an unjust condition within their political community. The paper focuses on the question of why some such “citizens” choose to participate in hunger strikes, which appears as an individual commitment to achieve a certain common objective. In doing so, the meaning of the experiences of hunger strikers and their universal right to live are elaborated in relation to their political and moral views. Hunger strikes are suggested to be seen as voluntary fasting, undertaken as a means of civil disobedience against an injustice within the context of citizenship. As examples of non-violent political acts, hunger strikes are not only part of citizenship politics but also expressions of commitment to achieving one’s goals through non-aggressive means for the common good of all citizens. Moreover, they can also be considered examples of martyrdom/heroism because hunger strikers altruistically risk their life for a public cause. As a particular altruistic act, hunger strikes can also be viewed as an effective form of communication directed toward fellow citizens. Moreover, they are expressions of self-determination for having control over and for one’s own life conditions. Finally, hunger strikes can be conceptualized as a struggle for transforming the configuration of structures and practices of citizenship about which one is passionately concerned. In this context, hunger strikes seem to be struggles for recognition in a relationship between two subjects, in which one subordinates the other

Representing and consuming "the East" in cultural markets

"The East" is an exceptional territory identified with Kurdish ethnicity within the geographical boundaries of the Turkish nation. This paper focuses on a critical historical moment, circa 2000-2004, when the promise of peace in this region was coupled with the explosive growth of urban consumer markets, to bring into public circulation a host of commercialized images of "the East" and "Eastern people." It examines how "the East" became codified in popular television melodrama. It also tracks how "Eastern tourism" became incorporated into middle-class leisure practices. By juxtaposing television narratives and tourist narratives, it argues that the commodification in cultural markets both affirms its "exceptionalism" and challenges its taken-for-granted parameters

An analysis of human causal factors in Unmanned Aerial Vehicle (UAV) accidents

MBA Professional ReportHuman error has been identified as the major contributor in many severe aviation mishaps, even for accidents involving Unmanned Aircraft (UA) systems. The Department of Defense (DOD) has used the Human Factors Analysis and Classification System (HFACS) taxonomy successfully for ten years to discover the human error in UA mishaps. It is important not to ignore the indisputable human presence in UA and the possible human-related causal factors in UA mishaps so we might be better able to reduce and prevent possible incidents. HFACS with its four main and 19 subcategories is a useful framework for identifying which factors have arisen historically, and which of them should have priority. The results of this study reveals that among 287 causal factors attributed to 68 accidents, 65 percent of the factors were associated with humans. Moreover, this study also discloses that the rater who categorizes the factors can differently observe, understand, and interpret the findings of mishap investigation; thus, human error may even impact the categorization phase due to the rater’s perception. The research concluded that even though HFACS carried out its functionality well, further study is needed to conduct intense statistical analysis with unlimited data and to validate HFACS with more case studies and various raters.http://archive.org/details/annalysisofhumca1094544637Captain, Turkish Air Force1st Lieutenant, Turkish ArmyApproved for public release; distribution is unlimited

Comparison of the effectiveness of chlorine, ozone, and photocatalytic disinfection in reducing the risk of antibiotic resistance pollution

Effectiveness of conventional chlorine and ozone disinfection on reduction of antibiotic resistance was compared with less commonly applied heterogeneous photocatalytic process. For this purpose plasmid DNA isolated from a multi-resistant Escherichia coli (E. coli) HB101 was treated in two different concentrations with the three oxidation processes. Oxidative damage on the plasmid DNA was analyzed with gel electrophoresis by comparing the extent of conformational changes in the DNA structure. The effectiveness of the applied oxidant in reducing the risk of resistance transfer was also evaluated by comparing the ability of treated plasmid DNA to transform competent cells. Chlorine did not affect plasmid DNA structure at the studied doses, while ozone and photocatalytic treatment resulted in conformational changes and the damage increased with increasing oxidant doses. Transformation experiments confirmed a similar trend. Chlorine did not affect the transformability and the cell counts of competent cells transformed with chlorine treated plasmid DNA were similar to those transformed by non-treated plasmid DNA in the control experiments

Genetic variation among pathotypes of Verticillium dahliae Kleb. from cotton in western Turkey revealed by AFLP

WOS: 000327295000009Cotton (Gossypium hirsutum L.) is crucial for the textile industry worldwide. Among the diseases attacking cotton, Verticillium wilt caused by Verticillium dahliae Kleb. is the most significant. Isolates of V. dahliae can be classified into defoliating and non-defoliating pathotypes. Thirty-two isolates of the non-defoliating pathotype and one isolate of a virulent, defoliating pathotype were analysed by the amplified fragment length polymorphism (AFLP) method. Three hundred and forty AFLP fragments were obtained with nine primer combinations. The number of total bands per primer pair ranged from 16 to 81, with an average of 37.7. The average polymorphism information content (PIC) value for the AFLP products was 0.50. Using the genotypic data, genetic distance analysis was performed. The maximum variation was found between isolates (Vd11) Nazilli and (Vd16) Soke, at a value of 0.79 and the minimum variation was found between isolates (Vd20) Aydin and (Vd14) Soke, at 0.24. The unweighted paired group method with arithmetic averages cluster analysis (UPGMA) was used to discriminate the V. dahliae isolates into five subgroups. Defoliating pathotypes (Vd33) from Soke province formed a single subgroup. As a result, it was found that there was significant variation among Verticillium isolates. AFLP analysis is an efficient and effective marker technology for determining genetic relationships among Verticillium isolates

Economic liberalization and the antecedents of top management teams: evidence from Turkish 'big' business

There has been an increased interest in the last two decades in top management teams (TMTs) of business firms. Much of the research, however, has been US-based and concerned primarily with TMT effects on organizational outcomes. The present study aims to expand this literature by examining the antecedents of top team composition in the context of macro-level economic change in a late-industrializing country. The post-1980 trade and market reforms in Turkey provided the empirical setting. Drawing upon the literatures on TMT and chief executive characteristics together with punctuated equilibrium models of change and institutional theory, the article develops the argument that which firm-level factors affect which attributes of TMT formations varies across the early and late stages of economic liberalization. Results of the empirical investigation of 71 of the largest industrial firms in Turkey broadly supported the hypotheses derived from this premise. In the early stages of economic liberalization the average age and average organizational tenure of TMTs were related to the export orientation of firms, whereas in later stages, firm performance became a major predictor of these team attributes. Educational background characteristics of teams appeared to be under stronger institutional pressures, altering in different ways in the face of macro-level change
