the objective of this study was to evaluate whether the adverse effects of high dietary rice bran (rb) inclusion levels on the feed intake, performance, bone status and nitrogen (n) retention of broilers could be mitigated by wet feeding. giving a completely randomized design experiment in 2 × 2 factorial arrangement, seventy two broiler chickens, managed in 24 floor pens received one of the tw...

Two-level factorial and fractional factorial designs have played a prominent role in the theory and practice of experimental design. Though commonly used in industrial experiments to identify the significant effects, it is often undesirable to perform the trials of a factorial design (or, fractional factorial design) in a completely random order. Instead, restrictions are imposed on the randomi...

Factorial designs for clinical trials are often encountered in medical, dental, and orthodontic research. Factorial designs assess two or more interventions simultaneously and the main advantage of this design is its efficiency in terms of sample size as more than one intervention may be assessed on the same participants. However, the factorial design is efficient only under the assumption of n...

Foldover is a widely used procedure for selecting follow-up experimental runs. As foldover designs require twice as many runs as the initial design, they can be inefficient if the number of effects to be dealiased is smaller than the size of the original experiment. Semifolding refers to adding half of a foldover fraction and is a technique that has been investigated in recent literature for re...

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. they w...

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...

The main objective of this study was to determine the effects of vermicompost and amino acids on the qualitative and quantitative yield of chamomile. The experiment was conducted during the growing season of 2010 at the Alborz Medical Research Center. The Treatment groups consisted of vermicompost (0, 5, 10, 15 and 20 tons/ha) and the sprays of amino acids (budding stag, flowering stage, and bu...

Serological cross-reactivity between the products of the H-2K and H-2D genes has been demonstrated by a design in which antibody was produced against determinants controlled by one locus (e .g . H-2K(k)), and then tested against the product of the opposite locus (e .g . H-2D(d)). A total of 13 out of 18 such test combinations exhibited H-2K-H-2D cross-reactivity. The presence or absence of cros...

We present a design of experiments (DOE) technique for microwave/millimeter wave flip chip characterization and optimization. Two optimization approaches, signal bump misalignment and transmission line compensation, are combined together for optimal performance for high frequency operation. First, the design of experiments method is presented and its advantages are emphasized. Then, the two tec...
