In unicellular animals, gas exchange allows gases to move freely directly in and out of the cell. In plants, the leaves act as a respiratory membrane, with small capillary vessels in the leaves acting to transport gases and nutrients throughout the tree. Animals like amphibians may rely on ...
The exchange of gases may occur through a passageway in the piston rod portion connected to the piston and extending from a location within the at least one combustion chamber to an area external to the cylinder, and through the exhaust ports formed in the peripheral wall of the cylinder. By...
Gas exchange is the process of an organism exchanging waste gases for those it needs to function. In humans, gas exchange consists...
The exchange capacity of the IERs can be regenerated, but a large number of secondary waste liquids will be produced during the regeneration process. The spent resins produced in nuclear power plants are usually not recycled, but directly discharged from the equipment, stored in stainless steel ...
Ammonia is a key component of plant metabolism, so that ammonia emission may occur from plants in relation to nitrogen nutrition and plant growth stage. In contrast, ammonia is highly soluble and may be efficiently captured by leaf cuticles and surface wetness allowing large deposition velocities....
blood in the surrounding capillaries, so oxygen diffuses from the saturated water coating the alveoli, across the alveolar wall, through the capillary wall and into the oxygen-depleted blood." The capillaries are thin and offer a large surface area to allow easy diffusion of gases. Hope this ...
Proton exchange membrane fuel cell (PEMFC) has a promising future in the power generation and transportation fields. Recirculation of unused anodic gases is fundamental to achieve a high-performance energy system, and this is usually attained employing ejectors or pumps. With respect to the latter,...
The process, including the increase in the volume of the plant and mass of the plant through the division and differentiation of the plant cell, is known as plant growth. The process may include the formation of plant structures, but it is not necessary, and relies on available nutri...
it is also beneficial to include bio-based renewable materials as renewable energy resources within these relationships. Due to the relatively low energy density and dispersed nature of bio-based resources, their integration with the resource demands of plants must be achieved through supply chain opti...
These IEMs have been also used in ED plants concentrating seawater in order to produce table salt, where it is essential to increase the monovalent ion selectivity [70]. Concerning the second class of manufacturing methods, polyethylene, polypropylene and fluorocarbon polymers are used for IEMs ...
