Bioclimatic analysis of Iranian climate for energy conservation in architecture
In order to design energy conscious buildings we need to know the climate of each country. In this study a bioclimatic analysis of Iranian climate had been done. Iran is a large country with different kinds of climate and basically includes four different climatic regions such as temperate-humid in southern shores of Caspian Sea, hot-humid in northern shores of Persian Gulf and Oman Sea, very cold and long winter...

Hematological assessments of sericin-derived oligopeptides in BALB/c mice
Sericin, a protein removed from the silk cocoons, possesses various biological activities. Due to less solubility, utilization of the sericin protein may be limited. Enzymatic hydrolysates of this protein would thus, provide an alternative. Since safety assessment is required before any protein hydrolysates being used, the effects of sericin-derived oligopeptides (SP) on some hematological parameters were evaluated....

Alteration of lymphocyte subpopulations in mice fed lutein from marigold extract
Lutein, a member of the xanthophyll carotenoids, has a wide variety of health benefits. These include prevention of age-related macular degeneration or cataracts and protection of ultraviolet -induced skin damage. Lutein also possesses anti-tumor and immune modulatory activities in BALB/c mice. However, in such animal model, the effects of lutein on lymphocyte subpopulations have not yet been assessed...

Induction of cholangiocarcinoma cells apoptosis by an andrographolide analog
Cholangiocarcinoma (CCA) is a malignant tumor derived from bile duct epithelial cells that has high incidence in the Northeastern area of Thailand. It is associated with the infection of liver fluke (Opisthorchis viverrini). Chemotherapeutic treatment of CCA is often ineffective due to its resistance to drugs. Therefore, new effective agents for treatment of CCA are urgently required. RSPP 050 analog is a modified...

Preparation of nanocrystalline strontium titanate (SrTiO3) powder by sol-gel combustion method
Nanocrystalline strontium titanate (SrTiO3, ST) powders were prepared by sol-gel combustion method. The influence of fuel content ratio (ratio of citric acid (CA) and total metal nitrate (MN); Ra = CA:MN) and calcination temperature were investigated on the structure, morphology, and crystallite size by X-ray diffraction (XRD) and scanning electron microscopy (SEM). The results indicate that the Ra ratio of 3:1 is...

Natural partial order on a semi group of self-E-preserving transformations
Let T(X) denote the full transformation semigroup on a set X. For an arbitrary equivalence relation E on X, we consider a sub semi-group of T(X) defined by: TSE(X)={α∈T(X):(x,xα)∈E for each x∈X} which is called the self-E-preserving transformation semi-group on X. In this paper, we discussed a natural partial order on TSE (X) and...

Riboflavin production by Candida tropicalis isolated from seawater
Screening of Candida spp. capable of riboflavin production from seawater samples in Chonburi province was conducted. Total of 47 isolates were identified asCandida tropicalis and Candida krusei with similar percentages of distribution. Among those identified isolates, only two of C. tropicalis, MICBUU002 and MICBUU019, were found to be able to produce riboflavin with...
