In 1985, fifty Jersey cows were imported to Pakistan from United States of America (USA). This paper compares milk production and reproduction performance of imported cows and their daughters under USA and Pakistan conditions. The imported cows which had yielded 5,858 kg, of milk (305 d lactation) in the USA produced only 3,192 kg, at NARC. The milk production of their daughters averaged 2,617 kg, being 22% lower than their mothers under the same environment at NARC. Year and season of calving had no significant effects on milk production. Average milk production of the first lactation was 10% lower than the mean of the second, third and fourth lactations, but, the differences between lactation means were non-significant. Mean calving interval in the USA was 385 days, whereas the same cows had a longer (p<.01) calving interval of 490 days at NARC. The calving interval of the daughters was longer (452 d; p<.01) than their mothers calving interval in the USA, and shorter (p<.01) than their mothers calving interval in Pakistan. The low age at first calving suggests that locally born Jersey cows were not reproductively disadvantaged by the local environment and nutrition, suggesting the adaptability of this breed in the new environment.

<P><B>Abstract</B></P> <P>Although the roles of many DEAD-box RNA helicases (RHs) have been determined in the nucleus as well as in cytoplasm during stress responses, the importance of chloroplast-targeted DEAD-box RHs in stress response remains largely unknown. In this study, we determined the function of BrRH22, a chloroplast-targeted DEAD-box RH in cabbage (<I>Brassica rapa</I>), in abiotic stress responses. The expression of <I>BrRH22</I> was markedly increased by drought, heat, salt, or cold stress and by ABA treatment, but was largely decreased by UV stress. Expression of BrRH22 in <I>Arabidopsis</I> enhanced germination and plantlet growth under high salinity or drought stress. BrRH22-expressing plants displayed a higher cotyledon greening and better plantlet growth upon ABA treatment due to decreases in the levels of <I>ABI3, ABI4,</I> and <I>ABI5</I>. Further, BrRH22 affected translation of several chloroplast transcripts under stress. Notably, BrRH22 had RNA chaperone function. These results altogether suggest that chloroplast-transported BrRH22 contributes positively to the response of transgenic <I>Arabidopsis</I> to abiotic stress by affecting translation of chloroplast genes via its RNA chaperone activity.</P> <P><B>Highlights</B></P> <P> <UL> <LI> Expression of cabbage RNA helicase BrRH22 is differentially affected by abiotic stresses. </LI> <LI> BrRH22 is localized to chloroplasts and possesses RNA chaperone activity. </LI> <LI> BrRH22 plays a positive role in seed germination and seedling growth under stress conditions. </LI> <LI> BrRH22 enhances seedling growth and cotyledon greening by decreasing <I>ABI3, ABI4,</I> and <I>ABI5.</I> </LI> </UL> </P>

<P><B>Abstract</B></P> <P>The plant cellulose synthase gene superfamily belongs to the category of type-2 glycosyltransferases, and is involved in cellulose and hemicellulose biosynthesis. These enzymes are vital for maintaining cell-wall structural integrity throughout plant life. Here, we identified 78 putative cellulose synthases (CS) in the soybean genome. Phylogenetic analysis against 40 reference <I>Arabidopsis</I> CS genes clustered soybean CSs into seven major groups (CESA, CSL A, B, C, D, E and G), located on 19 chromosomes (except chromosome 18). Soybean CS expansion occurred in 66 duplication events. Additionally, we identified 95 simple sequence repeat makers related to 44 CSs. We next performed digital expression analysis using publically available datasets to understand potential CS functions in soybean. We found that CSs were highly expressed during soybean seed development, a pattern confirmed with an Affymatrix soybean IVT array and validated with RNA-seq profiles. Within CS groups, CESAs had higher relative expression than CSLs. Soybean CS models were designed based on maximum average RPKM values. Gene co-expression networks were developed to explore which CSs could work together in soybean. Finally, RT-PCR analysis confirmed the expression of 15 selected CSs during all four seed developmental stages.</P>
A Design Evaluation of Strained Si-SiGe on Insulator (SSOI) Based Sub-50 nm nMOSFETs
Nawaz, Muhammad,Ostling, Mikael The Institute of Electronics and Information Engin 2005 Journal of semiconductor technology and science Vol.5 No.2
A theoretical design evaluation based on a hydrodynamic transport simulation of strained Si-SiGe on insulator (SSOI) type nMOSFETs is reported. Although, the net performance improvement is quite limited by the short channel effects, simulation results clearly show that the strained Si-SiGe type nMOSFETs are well-suited for gate lengths down to 20 nm. Simulation results show that the improvement in the transconductance with decreasing gate length is limited by the long-range Coulomb scattering. An influence of lateral and vertical diffusion of shallow dopants in the source/drain extension regions on the device performance (i.e., threshold voltage shift, subthreshold slope, current drivability and transconductance) is quantitatively assessed. An optimum layer thickness ($t_{si}$ of 5 and $t_{sg}$ of 10 nm) with shallow Junction depth (5-10 nm) and controlled lateral diffusion with steep doping gradient is needed to realize the sub-50 nm gate strained Si-SiGe type nMOSFETs.

<P><B>Abstract</B></P> <P>Korea is considered one of the centers of genetic diversity for cultivated as well as wild soybeans. Natural habitats of wild soybeans are distributed across the Korean mainland and the islands surrounding the Korean peninsula. In this study, the genetic diversity of 100 mainland Korean wild soybean accessions was evaluated by using 42 simple sequence repeat markers covering 17 soybean chromosomes. All analyzed loci were polymorphic and a total of 114 alleles were found. The observed average genetic diversity was low (0.4). The results showed that the 100 selected accessions did not exactly follow the geographical distribution. These results were further confirmed by the phylogeny inferred from five morphological characteristics (i.e., leaf shape, leaf area, plant shape, seed area, and 100-seed weight). Together, the genetic and morphological evaluations suggested conclusively that the selected population did not follow the geographical distribution pattern. The present study could provide useful information for the <I>ex situ</I> conservation and exploitation of wild soybean accessions in soybean improvement stratagems, and will aid in further understanding about the phylogeography of the species in the Korean center of diversity.</P> <P><B>Highlights</B></P> <P> <UL> <LI> Microsatellite analysis and morphological characterization of Korean wild soybean was done. </LI> <LI> Korean mainland wild soybeans have low genetic diversity. </LI> <LI> Selected populations do not follow geographical distribution pattern. </LI> </UL> </P>

Nawaz, M.,Khan, M.A.,Qureshi, M.A.,Rasool, E. Asian Australasian Association of Animal Productio 1999 Animal Bioscience Vol.12 No.1
Data from 22837 lambings of Lohi and Kajli ewes from 1962 through 1994 were used to analyse productive and reproductive traits and wool production, Overall litter size at birth averaged 1.33 being 1.45 for Lohi and 1.21 for Kajli ewes. The corresponding values at weaning were 1.23, 1.32 and 1.14, respectively. Litter size was consistently lowest for one year old, with a substantial increase at two, three and four years of ewe age and marginal increase thereafter, Ewes lambing in spring weaned 0.08 more lambs per parturition than ewes lambed in Autumn (p<0,01). Lamb birth weights were affected by ewe breed (p<0.01) and increased with ewe age. Overall lamb weaning weight (120 d) of 17993 lambs was 20.3 kg. Weaning weight was affected by breed, sire, year of birth, sex, rearing rank and weaning age (p<0.01). The highest mean weaning weight was 21.9 kg for Lohi lambs followed by Kajli lambs (18.8 kg), Lambs from Kajli ewes were 9% heavier at birth but 14% lighter at weaning. Twin born lambs were 18% lighter at birth and 13% at weaning than single born lambs. Male lambs were 3% heavier at birth and 4.5% heavier at weaning than female lambs. Overall annual mean wool production was 2,64 kg, Kajli ewes were heavier at breeding than Lohi ewes (i.e. 46.2 vs 44.8 kg). Lohi ewes being 3% less body weight produced 38% more wool and 18% more litter weaning weight than Kajli ewes, When average weight of lamb weaned per ewe weaning lambs was adjusted for ewe average metabolic body size, Lohi ewes were most efficient (i.e. arbitrary assigned value of 100) compared to Kajli ewes achieving only 83% of Lohi level.

<P>Electrode and electrolytes are always playing a key role in developing good efficient devices. This paper reports the synthesis, characterization and application of low viscosity ionic liquid (1-ethyl 3-methyl imidazolium dicyanamide) incorporated into polymer matrix (PVDF-HFP). The samples were characterized using various experimental tools. Complex impedance spectroscopy shows that conductivity of polymer host increases with increasing ionic liquid (IL) concentration attains maxima and then decreases. Optical microscopy and scanning electron microscopy (SEM) reveals the reduction of crystalline matrix of polymer host by adding IL. The primarily fabricated devices using maximum conductivity film affirms that this material is promising candidate for dye sensitized solar cell (DSSC) and supercapacitor application.
