Parasitism examples range from annoying mosquitos that bite you when you’re outside to fleas and ticks biting dogs to fungi attached to trees and barnacles living on a crab’s shell, By definition, parasitism is where the parasite lives in (or on) a host and causes harm to the host. This can occur in plants, animals,
Solar energy has experienced tremendous growth in the United States in recent years. To further facilitate the deployment of residential solar photovoltaic (PV) systems, city governments hold an important role in enacting solar policies and improving local permitting processes. By doing so, city governments can potentially reduce “soft” (non-hardware) costs for solar energy installations and
Many countries are experiencing a fast demographic shift, the consequences of which for energy consumption and the environment have been studied but generally undervalued by policy-makers. The economics literature almost universally predicts that an aging population will increase residential energy demand and reduce transport-related energy use: older households spend more on heating and less on
Soil forms at the interface of the lithosphere, biosphere, atmosphere, and hydrosphere and is the foundation of terrestrial life. It is home to a large proportion of earth’s biodiversity and regulates important ecosystem services, such as food provision, flood regulation, and water infiltration, among others. In addition, soil functions and services are fundamental to our
The rapid development of aerospace technology demands engine components, especially turbine blades, to withstand high temperatures and meanwhile maintain high-temperature mechanical properties. Only reaching these goals can make the engine achieve greater thrust ratio and higher work efficiency. Nickel-based superalloys are widely utilized for this purpose. At present, the operation temperature of nickel-based superalloy has
The term neuron refers to an electrically excitable cell specialized for the reception, processing, and transmission of information (electrochemical signals) throughout the nervous system and the rest of the body. Neurons are the principal structural and functional blocks of the central and peripheral nervous system empowering fast, accurate, and coordinated information exchange between various body parts
Petroleum use in the United States (U.S.) in 2016 was 5 percent lower than in 2005, and imports declined by 26 percent over the same period. Still, petroleum continues to account for 92 percent of all transportation fuels in the U.S. Oil market shocks, arising from conflicts in the world’s oil-producing regions and transportation areas,
The heat coming out from the oxidation of hydrocarbons which is identified by combustion is a major source of energy responsible for almost 98% of total energy worldwide. The prevalent types of the fuels used in the combustion for the production of energy were hydrocarbons which are being extracted from the shell of the earth.
Water is essential for human survival and well-being and plays an important role in many sectors of the economy. However, water resources are irregularly distributed over space and time, and they are under pressure due to human activity and economic development (Forslund et al., 2009). Accelerated urbanization and the expansion of municipal water supply and
Healthy eating is the basis for the health, growth, and development of children [1]. A child’s health is largely determined by his eating habits and health behavior adopted during childhood, and these are known to persist during adulthood [2]. Calorie-dense, less nutritious foods are, however, increasingly occupying large and disproportionate space on children’s plates, while
