By introducing Colpitts oscillator as a chaotic system, this paper deals with back-stepping control method and investigates the restrictions and problems of the controller where non-existence of a suitable response in the presence of uncertainty is the most important problem to note. In this paper, the back-stepping sliding mode method is introduced as a robust method for controlling nonlinear ...

Software-Produktlinien-Entwicklung bietet eine systematische Wiederverwendung von Software-Artefakten. Auf Grund der Tatsache, dass viele Produkte aus einer Produktlinie abgeleitet werden können, ist es unerlässlich Testverfahren zu entwickeln, die zum einen eine möglichst vollständige Abdeckung von allen möglichen Produkten sicherstellen und zum anderen weniger aufwändig sind, als jedes Produk...

Paenibacillus larvae is the causative agent of American Foulbrood (AFB), the most severe bacterial disease that affects honeybee larvae. AFB causes a significant decrease in the honeybee population affecting the beekeeping industry and agricultural production. After infection of larvae, P. larvae secretes proteases that could be involved in the pathogenicity. In the present article, we present ...

in a control structures, it is often preferred to minimize the gate width while utilizing the canal width in full for a stilling basin. therefore, to reach this, a gradually diverging stilling basin may be used. in this study, the effect of broad-crested sill on the expanding hydraulic jump in a rectangular channel was investigated. a total number of 79 tests were carried out for the range of i...

The small GTPase Rab2 is required for membrane transport between the endoplasmic reticulum (ER) and the Golgi complex. Rab2 associateswith pre-Golgi intermediates (also termed vesicular tubular clusters; VTCs) that sort cargo to the anterograde pathway from recycling proteins retrieved to the ER. Our previous studies have shown that Rab2 stimulates atypical protein kinase C / (aPKC / ) and glyc...

One of the characteristic events that occurs during phloem differentiation in dicotyledonous plants is the appearance of phloem protein within the sieve elements and companion cells of the phloem tissue (Esau and Cronshaw, 1967). Two very abundant phloem proteins, PPl and PP2, have been isolated from phloem exudates of pumpkin (Cucurbita maxima) (Read and Northcote, 1983). PPl is a 96-kD struct...

the purpose of this study was to profiled the body composition, anthropometric and physical fitness qualities of iranian national adolescent volleyball players, and quantified relationships between these characteristics. the sample of this study was 40 national adolescent volleyball players (age: 17.9±0.3). body composition factors: (weight, bmi, whr, body fat percentage, muscle mass) and anthr...

Regulation of swelling-activated Cl(-) current (I(Cl,swell)) is complex, and multiple signaling cascades are implicated. To determine whether protein tyrosine kinase (PTK) modulates I(Cl,swell) and to identify the PTK involved, we studied the effects of a broad-spectrum PTK inhibitor (genistein), selective inhibitors of Src (PP2, a pyrazolopyrimidine) and epidermal growth factor receptor (EGFR)...
