Through their effects on physicochemical features of floral nectar, nectar-dwelling yeasts can alter pollinator behavior, but the effect of such changes on pollination success and plant reproduction is unknown. We present results of experiments testing the effects of nectar yeasts on foraging patterns of captive and free-ranging bumble bees, and also on pollination success and fecundity of the ...

Artificial diets prepared with wheat germ, soybean protein, dextrosol, potato starch, sucrose, cellulose, soybean or sunflower oil, and vitamin solution for rearing Nezara viridula (L.) and Euschistus heros (Fabricius) were tested under controlled temperature (25 +/- 1 degrees C), RH (60 +/- 10%), and photophase (14h). Three diets were tested and compared with the natural diet privet [soybean a...

In many organisms, large offspring have improved fitness over small offspring, and thus their size is under strong selection. However, due to a trade-off between offspring size and number, females producing larger offspring necessarily must produce fewer unless the total amount of reproductive effort is unlimited. Because differential gene expression among environments may affect genetic covari...

Small heat shock proteins (sHSPs) are a diverse group of proteins and are highly abundant in plant species. Although majority of these sHSPs were shown to express specifically in seed, their potential function in seed physiology remains to be fully explored. Our proteomic analysis revealed that OsHSP18.2, a class II cytosolic HSP is an aging responsive protein as its abundance significantly inc...

A core component of Sentiment Analysis is the generation of sentiment lists. Label propagation is equivocally one of the most used approaches for generating sentiment lists based on annotated seed words in a manual manner. Words which are situated many hops away from the seed words tend to get low sentiment values. Such inherent property of the Label Propagation algorithm poses a controversial ...

Sweet corn seeds are sensitive to storage due their low starch content and poor seed vigor. Therefore, it is important understand physiological biochemical behavior during prolong longevity prevent the loss of The purpose this study was elucidate changes in sweet storage. Artificial accelerated aging natural were applied 19 inbred lines. We found that GP, GR VI decreased as proceeded. character...

there are many approaches for solving variety combinatorial optimization problems (np-compelete) that devided to exact solutions and approximate solutions. exact methods can only be used for very small size instances due to their expontional search space. for real-world problems, we have to employ approximate methods such as evolutionary algorithms (eas) that find a near-optimal solution in a r...

The results from simulations with a new three-dimensional treatment planning system for interstitial hyperthermia with ferromagnetic seeds are presented in this study. The thermal model incorporates discrete vessel structures as well as a heat sink and enhanced thermal conductivity. Both the discrete vessels and the ferroseeds are described parametrically in separate calculation spaces. This pa...

The three primate species of Santa Rosa National Park, Costa Rica (Ateles geoffroyi, Alouatta palliata, Cebus capucinus) have diets in which fruits are major components. All three primate species defecated seeds of many fruiting species; the majority of which (60%) germinated under experimental conditions. The sampling of seed traps placed throughout he forest indicated that, on average, 392 la...
