Representations of femininity in video games and other media are often discussed with reference to the most popular games, their protagonists and their sexist predicament. This framing leaves in shadow other dimensions. We aim to identify some of them and to open a broader horizon for examining and designing femininity and gender in games. To this end we look into games with creative portrayals...

Switchgrass, Indiangrass, and big bluestem are warmseason grasses that are a suitable alternative for summer pasture in Iowa. Their advantage over cool-season grasses such as bluegrass, bromegrass, and orchardgrass is their ability to produce during midsummer. These warm-season perennial grasses start growing in late spring as air and soil temperatures increase. Leaf growth often occurs in earl...

BACKGROUND Ethiopia faces cyclic food insecurity that alternates between pre- and post- harvest seasons. Whether seasonal variation in access to food is associated with child growth has not been assessed empirically. Understanding seasonality of child growth velocity and growth deficit helps to improve efforts to track population interventions against malnutrition. The aim of this study was ass...

introduction the study of growth parameters such as net assimilation rate (nar), leaf area ratio (lar), relative growth rate (rgr) and leaf area duration (lad) are important for analyzing yield constraints. the growth parameters can be used to understand the crop response to environmental variables during the growing season. the aims of the present study were to 1) consider the growth indices u...

The purpose of this study is to investigate the differences fatty acids and hormonal parameters in the spawning and non-spawning season between the diploid and induced triploid Far Eastern catfish, Silurus asotus. The measured triploids were produced by cold shock for 50 min at 4℃ in May 2014, the spawning season of diploid was in May, and the non-spawning season was designated in January. Estr...

The spatial and temporal distribution of forage quality is among the most central factors affecting herbivore habitat selection. Yet, for high latitude areas, forage quantity has been found to be more important than quality. Studies on large ungulate foraging patterns are faced with methodological challenges in both assessing animal movements at the scale of forage distribution, and in assessin...

Records from a 76-year investigation into effects of line breeding and selection of Hereford cattle, and concurrent weather records, were used to assess effects of weather patterns on growth of suckling calves. Calf growth data were adjusted for trends arising from selection and inbreeding, and for effects of age of dam and sex of calf to produce clean estimates of year effects. Daily maximum a...

     Forage production of rangelands differs during different times of grazing season and in the same month of different years. In range management projects, grazing capacity calculated once during the grazing season, which coincides with the maximum production of rangeland species. This may cause more livestock entry into the rangeland during the grazing season, leading to more degradation. Th...

Limitations of rainfall and surface water resources farmers have to use both surface and subsurface resources for growing different crops. In this study optimal management of irrigation water allocation and cropping pattern utilizing conjunctive use of surface and subsurface water resources is studied. Also the effect of reducing water consumption in different growth stages with different irrig...

Drought is a normal, recurring feature of climate phenomena; it may occur virtually in all climatic regions. The effects of drought accumulate slowly and its impacts are spread over a larger geographical area than other natural hazards. Drought is a natural hazard originating from a deficiency of precipitation that result in a water shortage for some activities or some groups and is often assoc...
