Carbon dioxide is an important greenhouse gas and a major agent of climate change. This study quantified carbon (C) emissions from energy consumption and C storage and uptake by greenspace for three cities in middle Korea: Chuncheon, Kangleung, and Seoul. Carbon emissions were estimated using C emission coefficients for fossil fuels consumed. Carbon storage and uptake by woody plants were compu...
A hallmark of the immune response to influenza is repeated encounters with proteins containing both genetically conserved and variable components. Therefore, the B and T cell repertoire is continually being remodeled, with competition between memory and naïve lymphocytes. Our previous work using a mouse model of secondary heterosubtypic influenza infection has shown that this competition result...
A field experiment was conducted at the Bangladesh Agricultural University (BAU) to find out possible effects of alternate wetting and drying irrigation (AWDI) on the yield, water use and water use efficiency (WUE) of Boro rice. The experimental layout was furnitured using split-plot design (SPD) with two modern varieties (MV) of rice viz. BRRIdhan 28 and BRRIdhan 29, which received four irriga...
It is well accepted that cytotoxic lymphocytes specific for viruses (1), haptens (2), and minor histocompatibility antigens (HA) 1 (3, 4) recognize antigen in an H-2restricted fashion during the effector phase. Precisely how the precursors of these cells respond to antigen during the induction phase, however, is poorly understood. In the case of skin graft rejection (5-9) and delayed-type hyper...
Hyalu ron ic acid (HA), first isolated by Meyer (1r is a compound of considerable biological interest. This polysacchar ide has been found in m a n y an imal tissues, especially those of mesenchymal origin, and in the capsules of some types of bacter ia . Fur thermore , a mucinous polysacchar ide of the HA type was detected and isolated from fowl sarcoma by K a b a t (10) and by Claude (5). The...

in order to study the effect of the usage of vermicompost and mycorrhiza fertilizer usage on yield quantity and quality of soybean cultivar l17 in water deficit stress condition, an experiment was conducted as plots in a split at randomized complete blocks with four replications in agricultural research center in 2013 in khoramabad. the experiment treatments including irrigation in three levels...
Monoclonal antibodies (mAb) prepared against a synthetic peptide of influenza virus haemagglutinin (HA), containing a known T-cell determinant, were used to examine the mechanism of antigen-induced activation of HA-specific class II-restricted T-cell clones. Previous studies had shown that T-cell clones, established from mice primed by infection with influenza virus, recognize variable antibody...
Umbilical cord blood transplantation is applied as treatment for mainly pediatric patients with hematologic malignancies. The clinical results show a relatively low incidence of graft-versus-host disease and leukemia relapse. Since maternal cells traffic into the fetus during pregnancy, we questioned whether cord blood has the potential to generate cytotoxic T cells specific for the hematopoiet...
Brassicaceae seed meals produce ionic thiocyanate (SCN (-)), a bioherbicidal compound. This study determined the fate of SCN (-) in a field soil amended with seed meals of Sinapis alba, Brassica juncea, and Brassica napus and quantified crop phytotoxicity by monitoring carrot ( Daucus carota) emergence. Meals were applied at 1 or 2 t ha (-1), and soils were sampled to 35 cm for SCN (-). Maximum...
