Most agricultural animals used as food sources, such as pigs, chickens, and cattle are housed at high densities and in conditions of stress that facilitate the spread of infectious diseases.
Both poultry production and aquaculture confine animals at high density in conditions that are conducive to transmission of infectious agents and may reduce resistance to disease by induction of stress.
Between 750 and 850 km, the average accuracy of the models was generally better than 15% and the choice of the atmospheric density model was relatively inconsequential, both in conditions of low and high solar activity.
The emission of photoelectrons from the surface of a satellite in conditions of low density plasma plays crucial role for the spacecraft structure potential, which sets up on the value defined by condition of the currents balance - at steady state conditions total current to the satellite body should be zero.
This fear could pose substantial problems for pandemic influenza mitigation because those in urban areas may be strongly encouraged to remain isolated to avoid virus spread in conditions of population density and crowding.
The use of such efficient weapons in conditions of growing population density and restricted areas available for Natufian hunter gatherers can be considered as one of the factors that could have affected the subsequent transition to food production that took place in the early Holocene.
Birds or conspecifics within the canopy are easier to detect in conditions of lower vegetation density, and therefore, benefits of increasing horizontal vigilance in order to monitor conspecifics or to detect aerial predators are not the same as at EBQB.
Extended stays in space are hard on the human body, since in conditions of microgravity the spine stretches out, muscles tend to atrophy and bone density can decrease, among other problems.
Although no evidence was found for a notable change in tumor vessel density under conditions of EC JAM-C deletion, we hypothesized that perhaps the blood vessels formed in the KOs may be morphologically and/or functionally impaired.
An overlapping genomic region was detected in our current study as a regulator of optical density in paraquat conditions.
