Electromagnetic hypersensitivity syndrome

Some users of mobile handsets have reported feeling several unspecific symptoms during and after its use, such as flaming and tingling feelings in the skin of the head and extremities, fatigue, sleep disturbances, dizziness, loss of mental attention, reaction times and memory retentiveness, headaches, malaise, tachycardia and disturbances of the digestive system. Some researchers, implying a causal relationship, have named this syndrome as a new diagnostic entity, EHS or ES. The World Health Organization prefers to name it “idiopathic environmental intolerance", in order to avoid the insinuation of causation.

The structure of pollen

Each pollen grain contain vegetative cells only one in the greater part flowering plant but several in other seed plants and a generative cell contain a tube nucleus that produces the pollen tube and a generative nucleus that divide to form the two sperm cells. The group of cells is surrounded by a cellulose cell wall and a thick, rough outer wall made of sporopollenin.

Pollen is created in the microsporangium contained in the anther of an angiosperm flower, male cone of a coniferous plant, or male cone of other seed plants. Pollen grains come in a broad multiplicity of shapes, sizes, and surface markings characteristic of the species see photomicrograph at right. Most, but surely not all, are spherical, Pollen grains of pines, firs, and spruces are wing. The minimum pollen grain that of the Forget-me-not plant (Myosotis sp.), is approximately 6 µm (0.006 mm) in diameter.

Pollen grains may have furrows, the course of which classify the pollen as colpate or sulcate. The number of furrows or pores helps categorize the flowering plants, with eudicots having three colpi (tricolpate), and other groups having one sulcus.

Ionosphere

It is the division of the atmosphere that is ionized by solar radiation. It plays a significant part in atmospheric electricity and forms the inner edge of the magnetosphere. It has sensible importance because, among other functions, it influences radio propagation to distant places on the Earth. It is situated in the thermosphere and is responsible for auroras.

Battery electric vehicle

The electric car, EV, or simply electric vehicle is battery electric vehicles (BEV) that utilize chemical energy stored in rechargeable battery packs. Electric vehicles use electric motors and motor controllers in its place of internal combustion engines (Ices). Vehicles using both electric motors and Ices are examples of hybrid vehicles, and are not measured pure BEVs because they operate in a charge-sustaining mode. Hybrid vehicles with batteries that can be exciting externally to displace some or all of their ICE power and gasoline fuel are called plug-in hybrid electric vehicles (PHEV), and are pure BEVs during their charge-depleting mode. BEVs are frequently automobiles, light trucks, neighborhood electric vehicles, motorcycles, motorized bicycles, electric scooters, golf carts, milk floats, forklifts and similar vehicles.

BEVs were among the earliest automobiles, and are more energy-efficient than interior combustion, fuel cell, and most other types of vehicles. BEVs create no tire fumes, and minimal pollution if charged from most forms of renewable energy. Many are capable of acceleration more than that of conventional vehicles, are quiet, and do not produce noxious fumes. It has been optional that, because BEVs reduce dependence on petroleum, they enhance national safety, and mitigate global warming by alleviating the greenhouse effect.
