The law of diminishing marginal revenue states that once maximum efficiency is reached, the amount of profit earned per unit will decrease. This can be due to demand saturation (i.e., diminishing marginal utility for consumers) or escalating production costs (i.e., diminishing marginal product f...
land, water and energy security and sustainability. While strong evidence exists on the effects of climate variability on the production of these crops, so far multifaceted attributes of droughts—magnitude, frequency, duration, and timing—have been tackled mainly separately, for a limited...
First, in homeland security, at present, although between we and other countries not direct military conflict, also not faced with direct military danger.But, has some factors actually in direct or latent is affecting our country's homeland security.[translate] ...
At the positive terminal, the protons and electrons recombine with oxygen from the air in a chemical reaction that produces water. The water is given off from the exhaust pipe as water vapor or steam. This type of fuel cell is called a PEM (different people say this stands for polymer ...
Harunia Province has a relatively dry climate and is attracting a fast-growing population that has put increasing demands on its water supply. The two companies that supply water to the region have struggled to keep up with demand and still remain profitable. Yet now they are asking Harunian ...
Definitely. We don't even KNOW all factors affecting climate change. Still, the link between rising carbon dioxide and temperature looks much more solid that the link between money spent on fighting climate change and levels of carbon dioxide. ... Wait, you didn't wanted to talk about climat...
Exhaustion, below average living conditions, logistical challenges, limited social lives, carbs-only diets, no-walking policies, curfews (and plenty other factors) are all components of what it means to work “in the field”. Most humanitarian workers have to deal with these on a daily basis ...
Control rods made of materials such as cadmium and boron can be raised or lowered into the reactor to soak up neutrons and slow down or speed up the chain reaction. Water is pumped through the reactor to collect the heat energy that the chain reaction produces. It constantly flows around a...
the most critical factors affecting vegetation greenness in the study region. Specifically, soil moisture stress and specific land management practices associated with logging, grazing, and land clearing appeared to dominate vegetation browning in the Dosso Reserve. In contrast, the vegetation greening in...
