Groups were: 1) G-CSF+cef/met; 2) placebo+cef/ met; 3) G-CSF+ofl/met; 4) placebo+ ofl/met. G-CSF (20 g/kg) prophylaxis was applied three times.Methods: Survival at 120 h was analysed with the Kaplan Meier method.Results: Survival rate was best in the G-CSF+cef/met group ...
The 6 treatments were arranged in a 2 × 3 factorial design with 2 levels of PDIE and 3 different AA profiles. The cows received either a low-protein (LP) or high-protein (HP) diet according to a changeover design, with a 3-wk period for each level. Each 3-wk period was further ...
Factorial design in two levels was applied to investigate the impact of water addition, time, and temperature to mechanical strength of solidified material. Factors time and temperature, as well as the interaction between the addition of water and time significantly (α = 0.05) influenced the ...
The Plackett-Burman Design (PBD) was used to select the statistically significant factors that are considered to influence the biomass concentration of Chlorella sp. HS236. After the selection of three significant factors using the PBD, a factorial response surface methodology (RSM) was utilized to...
Some classes of orthogonal $2sp {nsb 1}times 3sp {nsb 2}$ mixed factorial designs of median-resolution. CT Liao - 《Statist.probab.lett》 被引量: 0发表: 2001年 Combinatorics of experimental design This book is likely to be of great value to statisticians as well as to combinatorialists...
The study employs a 2x2 full factorial design [61]. The two factors will be access, through vouchers, to (1) ASP or (2) SDC. The four groups will be no program vouchers, ASP voucher only, SDC voucher only, and vouchers for both ASP and SDC. The study will last for 3 years, ...
Genetic function approximation (GFA) and multi-linear regression (MLR) approaches were used for the 2-D QSAR model building, while the fractional factorial design (FFD) and uninformative variable elimination-partial least square (UVEPLS) were employed for building the 3-D QSAR model. Pyridoxal ...
