This study was prepared to optimize $\alpha$-azuki bean powder content by sensory evaluation method when manufacturing bread with added $\alpha$-azuki bean powder. These sensory characteristics were designed to investigate sensory evaluation about appearance, color, texture, taste and overall acceptability of small red bean bread by balanced incomplete block design. According to evaluated mean of adjusted treatments, appearance was represented high value in bread with added 3% and 6% $\alpha$-azuki bean powder than bread without $\alpha$-azuki bean powder. Bread without $\alpha$-azuki bean powder was revealed maximum sensory score value of color among whole treatments and vread with added 6% $\alpha$-azuki bean powder was revealed second highest sensory value. As $\alpha$-azuki bean powder content increased, sensory score of texture, taste and overall acceptability increased. and bread added 12% $\alpha$-azuki bean powder revealed maximum sensory score. On the results of this research about sensory characteristics for manufacturing bread with added $\alpha$-azuki bean powder, bread with added $\alpha$-azuki bean powder was considered optimum when12% $\alpha$-azuki bean powder was added wheat flour because of highest score of texture, taste and overall acceptability in spite of lower score of appearance and color.

RFLP of PGC-$1{\alpha}$ gene of 285 Korean women was analyzed by PCR and HpaII restriction. We evaluated the correlation between PGC 1 genotypes and biochemical results, using the results of RFLP. Study subjects were divided into 3 groups: normal group (who has been average value of serum biochemical analysis), upper group (who has been higher value than average value), and low group (who have been lower value than average value). The frequencies of $H_1H_1$, $H_1H_2$, and $H_2H_2$ genotypes were 92 (32%), 85 (32%), and 108 (38%) respectively, and the ratio between $H_1$ and $H_2$ alleles was 1:1.1. There were no meaningful differences between biochemical results and PGC-$1{\alpha}$ genotypes in the normal group. But, in upper group, there was significant difference in total cholesterol (P=0.04) level. In the result of Turkey multiple comparison test, the P value of $H_1H_1$ and $H_2H_2$ was 0.059. In upper group, there were noticeable differences also in triglyceride (P=0.034) level and glucose (P=0.043) level, respectively. There were important differences between $H_1H_1$ type and $H_1H_2$ type in triglyceride (P=0.029) level and between $H_1H_2$ type and $H_2H_2$ type in glucose (P=0.040) level. This study may provide the PGC-$1{\alpha}$ genotype patterns for the amounts of lipid and glucose in the serum. $H_2$ allele (Ser482) of PGC-$1{\alpha}$ gene may be related with upper group in Korean women.

In this paper, we firstly use Krasnosel'skii fixed point theorem to investigate positive solutions for the following three-point boundary value problems for p-Laplacian with a parameter $({\phi}_P(D^{\alpha}_{0}+u(t)))^{\prime}+{\lambda}f(t, u(t))=0$, 0$D^{\alpha}_{0}+u(0)=u(0)=u{\prime}{\prime}(0)=0$, $u^{\prime}(1)={\gamma}u^{\prime}(\eta)$ where ϕ_p(s) = |s|^p−2s, p > 1, $D^{\alpha}_{0^+}$ is the Caputo's derivative, α ∈ (2, 3], η, γ ∈ (0, 1), λ > 0 is a parameter. Then we use Leggett-Williams fixed point theorem to study the existence of three positive solutions for the fractional boundary value problem $({\phi}_P(D^{\alpha}_{0}+u(t)))^{\prime}+f(t, u(t))=0$, 0$D^{\alpha}_{0}+u(0)=u(0)=u{\prime}{\prime}(0)=0$, $u^{\prime}(1)={\gamma}u^{\prime}(\eta)$ where ϕ_p(s) = |s|^p−2s, p > 1, $D^{\alpha}_{0^+}$ is the Caputo's derivative, α ∈ (2, 3], η, γ ∈ (0, 1).

The radical copolymerization with propagation and depropagation is presented in order to estimate reactivity rate of monomers and $K_{11}$(the equilibrium constant for propagation and depropagation) in the copolymerization of ${\alpha}-methylstyrene-co-methylmethacrylate$ and ${\alpha}-methylstyrene-acrylonitrile$. The value of ${\alpha}-methylstyrene$ and methylmethacrylate and $K_{11}$ are found to be 0.48, 0.47 and 5.0 respectively. The value of ${\alpha}-methylstyrene$ and acrylonitrile and the $K_{11}$ are found to be 0.1251, 0.0577 and 23.8 respectively. The treatment rate constant of ${\alpha}-methylstyrene-co-methylmethacrylate$ and ${\alpha}-methylstyrene-co-acrylonitrile$ in the copolymerization is estimated to be 2.5, 80.72 regardless of monomer feed composition.

Objectives: The objective of this study was to evaluate antidiabetic activity of Chaturmukha rasa based on streptozotocin induced diabetes model, alpha amylase inhibitory activity, alpha Glucosidase inhibitory activity and inhibition of sucrase. Methods: Chaturmukha rasa was prepared as per Ayurvedic formulary. Antidiabetic activity was measured in experimentally streptozotocin induced rats. The dose was taken as 45 mg/kg, i.p. The antidiabetic activity of Chaturmukha rasa was compared Triphala Kwatha, a marketed formulation. Further In vitro $\acute{\alpha}$- Amylase Inhibitory Assay, In vitro salivary amylase Inhibitory Assay, In vitro ${\alpha}-Glucosidase$ Inhibitory Assay and In vitro Sucrase Inhibitory Assay was performed with respect to Chaturmukha rasa. The IC50 value was calculated for all the above activity. Results: Streptozotocin with Acarbose showed significant decrease in blood glucose level whereas streptozotocin with Triphala kwatha showed more decrease in blood glucose level than Streptozotocin with Acarbose. The combination of Streptozotocin + Triphala kwatha + Chaturmukha rasa showed a significant decrease in blood glucose level on 21st day. In vitro $\acute{\alpha}$- Amylase Inhibitory Assay the Chaturmukha rasa showed IC50 value $495.94{\mu}l$ when compared with Acarbose $427.33{\mu}l$, respectively. In the ${\alpha}-Glucosidase$ Inhibitory Assay Chaturmukha rasa showed IC50 value $70.93{\mu}l$ when compared with Acarbose $102.28{\mu}l$, respectively. In vitro Sucrase Inhibitory Assay Chaturmukha rasa showed IC50 value $415.4{\mu}l$ when compared with Acarbose $371.43{\mu}l$, respectively. Conclusion: This study supports that Chaturmukha rasa may inhibit diabetes by inhibition of salivary amylase or alpha Glucosidase or sucrase. This may be the mechanism by which Chaturmukha rasa inhibits diabetes. Further this study supports the usage of Chaturmukha rasa for the management of diabetes.

4-probe resistivity measurement technique was used to study kinetics of hydrogen absorption-desorption on Pd film($520{\AA}$ thick) at room temperature upto 1 bar. Kinetics data are fitted well to 1st order kinetics equation in ${\alpha}$ and ${\alpha}^{\prime}$ phases. In ${\alpha}+{\alpha}^{\prime}$ phase, absorption kinetics was very complicated, but it could be explained partially with nucleation and growth process. Ln(dR/dt) vs. time plot gives rate constant k value(R is resistance of sample, t is time). k value for absorption is $4^{-6}{\times}10^{-4}/sec$ in ${\alpha}$ phase. k is increasing upto $4^{\times}10^{-2}/sec$ as hydrogen pressure increasing in ${\alpha}^{\prime}$ phase. k is proportional to ln(Pop/Peq), where Peq is equilibrium plateau pressure and Pop is the opposing pressure. In contrast to bulk sample k value was decreasing with increasing number of A-D cycling in ${\alpha}^{\prime}$ phase absorption.

Many reports have shown that the access pattern for geospatial tiles follows Zipf's law and that its parameter ${\alpha}$ represents the access characteristics. However, visits to geospatial tiles have temporal and spatial popularities, and the ${\alpha}$-value changes as they change. We construct a mathematical model to simulate the user's access behavior by studying the attributes of frequently visited tile objects to determine parameter estimation algorithms. Because the least squares (LS) method in common use cannot obtain an exact ${\alpha}$-value and does not provide a suitable fit to data for frequently visited tiles, we present a new approach, which uses a moment method of estimation to obtain the value of ${\alpha}$ when ${\alpha}$ is close to 1. When ${\alpha}$ is further away from 1, the method uses the associated cache hit ratio for tile access and uses an LS method based on a critical cache size to estimate the value of ${\alpha}$. The decrease in the estimation error is presented and discussed in the section on experiment results. This new method, which provides a more accurate estimate of ${\alpha}$ than earlier methods, promises more effective prediction of requests for frequently accessed tiles for better caching and load balancing.
