Yield is a quantitative trait and improving grain yield through direct selection is time-consuming. Indirect selection consisting of selection indices is more promising. A field experiment was conducted during 1999-2000 growing season in two experimental locations (Kooshkak and Badjgah) of College of Agriculture, Shiraz University, Shiraz. Thirteen corn hybrids were used in a randomized complet...
background: propolis, a honeybee product, has been used empirically for centuries and was always mentioned as an immunomodulatory. objectives: in this study, the effects of propolis on growth indices, innate immune responses and haematological parameters of barbus barbulus were investigated. methods: three hundred and sixty juvenile barbus barbulus, weighing 102±8.2g were randomly divided into ...
INTRODUCTION Intrauterine growth restriction (IUGR) is a major clinical issue for pregnant women. The purpose of this study was to evaluate color Doppler indices of the proximal and distal parts of the middle cerebral artery (MCA) of the fetus. METHODS In this cross-sectional study, 350 pregnant patients, with gestation age of 32-40 who were suspected to have intrauterine growth restriction, ...
Recognition of growth pattern and folding mechanism in the fold-thrust belts with hydrocarbon resources is important in exploration and development planning of oilfields. As the processes of tectonics, erosion, and geomorphology impact on each other, therefore, the investigation of a process, one can obtain information about the other process. In this research the tectonic process of transverse...
Some of most used indicators in marine ecology are nucleic acid-derived indices. They can be divided by target levels in three groups: 1) at the organism level as ecophysiologic indicators, indicators such as RNA:DNA ratios, DNA:dry weight and RNA:protein, 2) at the population level, indicators such as growth rate, starvation incidence or fisheries impact indicators, and 3) at the community lev...
One of the major issues in aquaculture is to keep balance between growth rate of fish and optimal use of consumed food. L-carnitine is considered an effective food supplement for fish growth. Sobaity seabream is one of the commercially important species in the Persian Gulf that is highly considered in aquaculture too. Growth indices and survival rate of 240 Sobaity fingerlings with mean weight ...
iran is located in dry belt of the earth and always involved with drought in different sections. drought has already caused many losses to natural plant cover, agriculture and human society. for drought monitoring, we can use some drought indecies. in this research, the standard index of annual precipitation)siap),sandardized precipitation index (spi) and palmer drought severity index (pdsi) we...
