mite
An order of small Arachnida with rounded bodies. Mites are very abundant in the soil, feeding on plant material and invertebrate animals. Some parasitic mites (e.g. red spider) damage crops and can be serious pests. Others cause diseases in animals. Ticks are blood-suckers, some being vectors of diseases such as Rocky Mountain spotted fever in humans and fowls, and louping ill in cattle and sheep. (Source: ALL)

Direct-on-line starting
Direct-on-line starting, which is often abbreviated as DOL, is perhaps the most traditional system and consists in connecting the motor directly to the supply network, thus carrying out starting at full voltage.Direct-on-line starting represents the simplest and the most economical system to start a squirrel-cage asynchronous motor and it is the most used.
As represented in Figure 5, it provides the direct connection to the supply network and therefore starting is carried out at full voltage and with constant frequency, developing a high starting torque with very reduced acceleration times.
The typical applications are relevant to small power motors also with full load starting.
These advantages are linked to some problems such as, for example, the high inrush current, which - in the first instants - can reach values of about 10 to 12 times the rated current, then can decrease to about 6 to 8 times the rated current and can persist to reach the maximum torque speed.The effects of such currents can be identified with the high electro-dynamical stresses on the motor connection cables and could affect also the windings of the motor itself; besides, the high inrush torques can cause violent accelerations which stress the transmission components (belts and joints) generating distribution problems with a reduction in the mechanical life of these elements.
Finally, also the possible electrical problems due to voltage drops on the supply line of the motor or of the connected equipment must be taken into consideration.
[ABB]Прямой пуск
Прямой пуск, который по-английски часто сокращенно обозначают как DOL, является, пожалуй наиболее распространенным способом пуска. Он заключается в непосредственном (т. е. прямом) подключении двигателя к питающей сети. Это означает, что пуск двигателя осуществляется при полном напряжении.Схема прямого пуска является наиболее простым, экономичным и чаще всего применяемым решением для электродвигателей с короткозамкнутым ротором.
Схема прямого подключения к сети представлена на рисунке 5. Пуск осуществляется при полном напряжении и постоянной частоте сети. Электродвигатель развивает высокий пусковой момент при коротком времени разгона.
Типичные области применения – маломощные электродвигатели, в том числе с пуском при полной нагрузке.
Однако, наряду с преимуществами имеются и определенные недостатки, например, бросок пускового тока, достигающий в первоначальный момент 10…12-кратного значения от номинального тока электродвигателя. Затем ток двигателя уменьшается примерно до 6…8-кратного значения номинального тока и будет держаться на этом уровне до тех пор, пока скорость двигателя не достигнет максимального значения.
Такое изменение тока оказывает значительное электродинамическое воздействие на кабель, подключенный к двигателю. Кроме того пусковой ток воздействует на обмотки двигателя. Высокий начальный пусковой момент может привести к значительному ускорению и следовательно к значительной нагрузке элементов привода (ремней, крепления узлов), что вызывает сокращение их срока службы.
И, наконец, следует принять во внимание возможное возникновение проблем, связанных с падением напряжения в линии питания двигателя и подключенного к этой линии оборудования.

fish kill
Fish diseases observed in the past three decades and which have been attributed to pollution include: haemorrhages; tumours; fin rot; deformed fins; and missing scales and tails. In industrialized countries, increasing numbers of fish are deemed inedible. Many small kills are not noticed or are not reported, and large kills are often not included because of insufficient information to determine whether the kills were caused by pollution or by natural factors. Low dissolved oxygen levels resulting from excessive sewage is one of the leading causes. The second most common cause is pesticides. (Source: WPR)

Can be caused by a variety of means, e.g. farm pollution from animal wastes and silage liquor (liquors from green leaf cattle food which has had molasses added to promote fermentation and preservation; they are highly polluting and can be a seasonal cause of fish deaths in small streams), leachate from landfill sites, and spoil heaps, solvent discharge to sewers or to land and inadequate sewage treatment works.
