Measurements of Global Navigation Satellite System (GNSS) receivers are affected by systematic offsets related to group and phase delays of the signal generation and processing chain. The resulting code and phase biases depend on the transmission frequency and the employed signal modulation. Within this study differential code biases (DCBs) of legacy and modernized GNSS signals are derived from...

INTRODUCTION: Surgical bypass for the treatment of lower extremity peripheral arterial disease is a suboptimal option in high-risk surgical patients or patients with limited life expectancy. Percutaneous transluminal angioplasty (PTA) is an alternative in such patients; however, the results of this approach have not been wellstudied in our region. This study evaluated the results of infrapoplit...

To date, al1 published CMOS field-programmable analog array (FPAA) designs have operated under lMHz bandwidths. This thesis develops circuit methods allowing the development of a CMOS FPAA operating at greater than lMHz frequencies. For this purpose the secondgeneration current conveyor (CCII) is used. IC test results of a O.8p-n CMOS chip containing four configurable analog blocks based on the...

conclusions in total, application of therapeutic approaches in patients with cad depends on many factors. in our study not only risk factors such as gender, lifestyle, smoking, alcohol abuse, diabetes and hypertension were associated with the incidence of cad, but also they were highly correlated with the severity of the disease. results the mean age of total patients was 58.3 ± 11.5 years (p =...

In a series of experiment, the response of two contrasting potato species, namely,  Solanum acaule (tolerant) and Solanum tuberosum cv. Agria (intolerant) to salt (80 mM NaCl) and drought stress (15% polyethylene glycol;PEG) was studied in vitro. Furthermore, the role of acetyl salicylic acid (ASA) (1 and 10 µM) in alleviating oxidative stress was investigated. In Agria cultivar, NaCl and PEG r...

In order to evaluate the effects of priming materials and duration of priming on the seed physiological enhancement and biochemical traits of germination in pumpkin seeds a factorial experiment was conducted based on a completely randomized design with three replications at the University of Mohaghegh Ardabili. Treatments were priming with water, NaCl (3%), gibberellic acid (20 mg L-1), and asc...
