Esmail Khosropour Leila Hakimi,

ROS detoxification is an essential process in protecting plant cells and their organelles, which is caused by ROS generated in stress condition. Peroxidase (POD) isozyme, Malondialdehyde (MDA) content, and Ascorbate peroxidase (APX) activity are the indicators of plants for measuring pollution effects. The purpose of the present study was to investigate Cd-induced stress on POD isozymes, MDA co...

The present study describes a liquid chromatography-tandem mass spectrometry (LC-MS/MS) method for the simultaneous determination of S-RRR and R-SSS nebivolol (nebivolol enantiomers) in human plasma using solid phase extraction technique. Method of both S-RRR and R-SSS nebivolol (nebivolol enantiomers) has been developed and validated using racemic nebivolol D4 as an internal standard. Analytes...

تنش شوری از عوامل مؤثر در جلوگیری از جوانه­زنی و استقرار گیاهچه محسوب می­گردد. نمک­ها در روند جوانه­زنی با محدود کردن مقدار آب در دسترس (اثر اسمزی) و یا به سبب صدمات ناشی از ورود یون­ها، در روند متابولیسم (اثر یونی) مؤثر می­باشند. به­منظور بررسی اثر تنش یونی و اسمزی ناشی از وجود نمک در محیط بذر دو گونه cristatum  Agropyronو Agropyron elongatum از محلول­های ایزواسمزی کلرید سدیم (NaCl) و پلی­اتیل...

This paper describes work which attempts to evolve circuit solutions for combinational logic systems directly onto Xilinx 6000 FPGA parts. The reason for attempting to evolve designs direct onto the device is twofold: (i) every circuit has a known functionality and (ii) every circuit must be able to be placed on the chip and then routed. Using evolutionary techniques allows us to consider these...

The similarity of mosquito sampling methods compared in northwestern NewJersey for The collecting techniques the standard New Jersey light trap, dry ice baited CDC miniature light trap and human bite The data indicated that the dry ice baited CDC trap closely agreed with the mosquito collections made with the bite Collections from the standard light trap, however, did accurately reflect the nui...

A reagent is described for the colorimetric enzymic determination of high-density-lipoprotein (HDL) cholesterol. The reagent can be used with HDL fractions isolated by the various methods of precipitation of low- and very-low-density lipoproteins we investigated. The considerable sensitivity obtained by use of Barham-Trinder's reaction allows the sample/reagent volume ratio to be decreased to 1...

Software distributed shared memory (DSM) platforms on networks of workstations tolerate large network latencies by employing one of several weak memory consistency models. Fully asynchronous parallel iterative algorithms offer an additional degree of freedom to tolerate network latency: they behave correctly when supplied outdated shared data. However, these algorithms can flood the network wit...

The QR factorization with column pivoting (QRP), originally suggested by Golub and Businger in 1965, is a popular approach to computing rank-revealing factorizations. Using BLAS Level 1, it was implemented in LINPACK, and, using BLAS Level 2, in LAPACK. While the BLAS Level 2 version delivers, in general, superior performance, it may result in worse performance for large matrix sizes due to cac...

The Indian islands of Lakshadweep in the Arabian sea are known to be endemic for bancroftian filariasis. However, malaria endemicity was reported to be associated with the invasion of vector species Anopheles tessellatus from Maldives. Indigenous transmission of malaria was recorded during 1972. Thereafter the National Anti-Malaria Programme (NAMP) brought these islands under DDT spray. Since 1...
