The chemical step in the chemoenzymatic synthesis of bioengineered heparin has been examined and optimized statistically using a response surface methodology. A four factor, two level full factorial design experiment and a three factor Box-Behnken design were carried out. The goal was to establish a method to prepare N-sulfo, N-acetyl heparosan of the desired N-acetyl content, number average mo...

Objective: This research was conducted to study the effectiveness of self-regulation training among female students’ academic achievement motivation in Birjand City, Iran. Methods: In this interventional comparative study (pretest-posttest design with control group), 84 eighth grade students (from public intermediate schools) in Birjand were selected through multi-stage cluster sampling. The...

Chamomile (Matricaria chamomilla L.) is one of the most important medicinal plants in Iran. The main objective of this study was to determine the effects of organic nutrients on the yield and oil content of chamomile. The experiment was conducted in the spring of 2010. The treatment groups consisted of vermicompost (0, 5, 10, 15 and 20 tons/ha) and the Aminol Forte sprays (no spraying or contro...

CMOS-MEMS is a promising approach to achieve integration of microelectromechanical structures with circuits by using foundry CMOS services coupled with post-CMOS processing. The most significant benefit is the low cost of manufacturing the mechanical structures with CMOS. We report suitable conditions for post-CMOS processing by reactive ion etching (RIE) to define the mechanical structures. Va...

Software testing is an expensive process, which is vital in the industry. Construction of the test-data in software testing requires the major cost and to decide which method to use in order to generate the test data is important. This paper discusses the efficiency of searchbased algorithms (preferably genetic algorithm) versus random testing, in software test-data generation. This study diffe...

to evaluate the effect of growth promoting bacteria on morphophysiologic traits and nutrient uptakes of two rice cultivars, an experiment was carried out in 2009-2010 cropping season in rice researches institute of rasht. the experiment design consisted of four randomized complete blocks in a factorial arrangement having 16 treatments in 4 replications. in this research, two factors were evalua...

State University of New York at Stony Brook 2A two-level factorial design can be uniquely represented by a polynomial indicator function. Therefore, properties of factorial designs can be studied through their indicator functions. This paper shows that indicator function is an effective tool in studying two-level factorial designs. Indicator function is used to generalize aberration criterion o...

Two experiments examined the effects of differences in the parameters of a clocked interfood interval on the obtained distribution of responding to the stimuli in that interval. In the first experiment, a 3 x 3 factorial design assessed the effects of the number of components and the durations of those components. Food was presented irrespective of behavior following 5, 10, or 20 discrete stimu...

The impact of 10 Fusarium species in concomitant association with Rotylenchulus reniformis on cotton seedling disease was examined under greenhouse conditions. In experiment 1, fungal treatments consisted of Fusarium chlamydosporum, F. equiseti, F. lateritium, F. moniliforme, F. oxysporum, F. oxysporum f.sp. vasinfectum, F. proliferatum, F. semitectum, F. solani, and F. sporotrichioides; Rhizoc...

abstract paclobutrazol is one of the most important triazolic compounds which are used as growth retardants in some crops. in this study, the effect of application methods and concentration of paclobutrazol on plant height of tuberose and possibility of pot production was investigated. in the first experiment, tuberose bulbs were soaked in 0, 25, 50, 75 and 100 mg.l-1 paclobutrazol for 10, 20 a...
