there are conflicting results concerning dc-sign and dc-signr vntr polymorphisms. the present study aimed to evaluate the possible association between dc-sign as well as dc-signr vntr polymorphisms and pulmonary tuberculosis (ptb) in a sample of iranian population. this case-control study was done on 171 ptb and 161 healthy subjects. the variants were detected by polymerase chain reaction (pcr)...

Cousinia (Asteraceae, Cardueae) cinsi çiçekli bitkiler içerisinde tür sayısı bakımından 50. büyük cins ve Asteraceae familyası yaklaşık 700 türle temsil edilen en cinslerden biridir. Bu çalışma, seksiyonu yer alan decolorans türünün anatomik, palinolojik mikromorfolojik özelliklerinin belirlenerek cinsin sistematiğine katkı sağlamak amacıyla yapılmıştır. C. polen özellikleri çalışılmış türe ait...

In this paper a complete robust control synthesis is performed for a hybrid power generation structure composed by a Fuel Cell and a Supercapacitor. The control strategies are applied to the DC-DC boost power converters associated to each power source. Multivariable PI control withH∞ performance,H∞ full and reduced order controllers are designed and compared. The multivariable PI controller is ...

This paper presents the basic characteristics of the digitally controlled boost type dc-dc converter. The static and dynamic characteristics of the dc-dc converter with the digital PID control are discussed. Especially, it is examined that the A-D conversion timing and anti-aliasing filter’s cut-off frequency affect the dynamic and static characteristics. As a result, when the anti-aliasing fil...
