Ülkelerin nüfusu; doğum, göç ve ölüm nedeniyle nitelik nicelik olarak değişen bir olgudur. Özellikle son yıllarda Türkiye’de eden nüfus içerisinde kadın sayısının artması ile birlikte doğurganlık davranışının değişmesi söz konusu olmuştur. Bu bağlamda kadınların sosyo-ekonomik uyum sağlama süreci alan yerlerdeki aile yapılarındaki değişimin anlaşılabilmesi için analiz edilmesi gerekmektedir. Do...

Abstract Ion acceleration resulting from the interaction of 11 fs laser pulses ~35 mJ energy with ultrahigh contrast (<10^-10), and 10^19 W/cm^2 peak intensity foil targets made various materials thicknesses at normal (0◦) 45◦ incidence is investigated. The maximum protons reached ~1.4 MeV accelerated in propagation direction ~1.2 opposite formvar target. An conversion efficiency to proton b...

Since their discovery in 1999 [1] the topic of laseraccelerated ions has attracted high attention both in the field of plasma-physics and in the accelerator community. In a typical laser-accelerated ion scheme a thin metal foil is irradiated by an ultra-intense chirped pulse amplified laser beam which leads to the generation of relativistic electrons. These electrons are accelerated through the...

The bacterial transposon Tn7 encodes five genes whose protein products are used in different combinations to direct transposition to different types of target sites. TnsABC + D directs transposition to a specific site in the Escherichia coli chromosome called attTn7, whereas TnsABC + E directs transposition to non-attTn7 sites. These transposition reactions can also recognize and avoid "immune"...

The bacterial transposon Tn7 utilizes four Tn7-encoded proteins, TnsA, TnsB, TnsC and TnsD, to make insertions at a specific site termed attTn7. This target is selected by the binding of TnsD to attTn7 in a sequence-specific manner, followed by the binding of TnsC and activation of the transposase. We show that TnsD binding to attTn7 induces a distortion at the 5' end of the binding site and Tn...

Menopoz üreme çağından, over fonksiyonlarındaki gerilemeye bağlı yeteneğinin kaybolduğu zamana doğru geçen dönemdir. Dünya Sağlık Örgütü’nün (DSÖ) tanımına göre menopoz; ovaryum aktivitesinin yitirilmesi sonucunda menstrüasyonun kalıcı olarak sonlanmasıdır. Ülkemiz 2018 TNSA sonuçlarına göre, kadınların 48-49 yaş grubundaki %45.1’i menopozdadır. 30-49 yaşları arasındaki ise %10.3’ünün menopozda...

Laser–plasma proton sources and their applications to preclinical research has become a very active field of in recent years. In addition small dimensions as compared classical ion accelerators, they offer the possibility study biological effects ultra-short particle bunches correspondingly high dose rates. We report on design an experimental setup for irradiation cell cultures at L2A2 laborato...

Respondent selection procedures are utilized to choose a particular respondent in surveys. In the 2013 Turkey Demographic and Health Survey (2013 DHS), all women who meet eligibility criteria were interviewed according standard regulations of International DHS Program. Simulating application different methods, this study mainly asks “How would main indicators produced differ with implementation...
