Nowadays researchers are focused on biological farming. In modern environmental conditions the reduction of the chemical load on the environment is a current issue. In the article the following plants are used as pest management, especially, with Colorado potato beetle: jimson weed, white hellebore, Camelina. They contain a lot of alkaloids and essential oils that inhibit weeds and frightening off potato pests.

Category : Index Not-Proofread. Namespaces Index Discussion. Views Read Edit View history. Title A Treatise on Electricity and Magnetism. James Clerk Maxwell.

To be proofread. Elementary Theory of Magnetism. Properties of a magnet when acted on by the earth. Potential of a magnet of finite size. Two expressions for this potential, corresponding respectively to the theory of polarization, and to that of magnetic 'matter'.

The north end of a magnet in this treatise is that which points north, and the south end that which points south. Boreal magnetism is that which is supposed to exist near the north pole of the earth and the south end of a magnet. Austral magnetism is that which belongs to the south pole of the earth and the north end of a magnet.

Austral magnetism is considered positive. The direction of magnetic force is that in which austral magnetism tends to move, that is, from south to north, and this is the positive direction of magnetic lines of force. A magnet is said to be magnetized from its south end towards its north end. Magnetic force in a cylindric cavity in a magnet uniformly magnetized parallel to the axis of the cylinder. The potential of a magnetic shell at any point is the product of its strength multiplied by the solid angle its boundary subtends at the point.

When a body under the action of magnetic force becomes itself magnetized the phenomenon is called magnetic induction. Case of a solid sphere, the coefficients of magnetization being different in different directions. Magnetic bodies tend towards places of most intense magnetic force, and diamagnetic bodies tend to places of weakest force.

Determination of the axis of a magnet and of the direction of the horizontal component of the magnetic force. Measurement of the moment of a magnet and of the intensity of the horizontal component of magnetic force. Definition of the earth's magnetic poles. They are not at the extremities of the magnetic axis.

False poles. They do not exist on the earth s surface. Proof that the force due to a straight current of indefinitely great length varies inversely as the distance. The action of this current compared with that of a magnetic shell having an infinite straight edge and extending on one side of this edge to infinity.

Deduction from this of the action of a closed circuit of any form and size on any point not in the current itself. The wire is urged from the side on which its magnetic action strengthens the magnetic force and towards the side on which it opposes it. Electromagnetic force is a mechanical force acting on the conductor, not on the electric current itself. Second experiment. A crooked conductor is equivalent to a straight one carrying the same current.

Third experiment. The action of a closed current as an element of another current is perpendicular to that element. Both circuits may, however, for mathematical purposes be conceived as consisting of elementary portions, and the action of the circuits as the resultant of the action of these elements.

Resolution of these in three directions, parallel, respectively, to the line joining them and to the elements themselves. Expression of the determinants in terms of the components of the vector-potential of the current. The part of the force which is indeterminate can be expressed as the space-variation of a potential. Helmholtz's deduction of induction from the mechanical action of currents by the principle of conservation of energy.

Lagrange's method furnishes appropriate ideas for the study of the higher dynamical sciences. The part depending on products of ordinary velocities and strengths of currents does not exist. If terms involving products of velocities and currents existed they would introduce electromotive forces, which are not observed. All the phenomena of the mutual action of two circuits depend on a single quantity, the potential of the two circuits.

 - Он обошел систему Сквозь строй. - Да… и… - слова застревали у нее в горле. Он убил Дэвида. Бринкерхофф положил руку ей на плечо. - Мы почти приехали, мисс Флетчер. Держитесь.

Беккер зашагал по улице с четырехполосным движением и бульваром посередине. Туда и обратно, - мысленно повторял.  - Туда и обратно. Он был настолько погружен в свои мысли, что не заметил человека в очках в тонкой металлической оправе, который следил за ним с другой стороны улицы. ГЛАВА 18 Стоя у громадного окна во всю стену своего кабинета в токийском небоскребе, Нуматака с наслаждением дымил сигарой и улыбался. Он не мог поверить в свою необыкновенную удачу.

Стратмор снова вздохнул. - Тот, который тебе передал Танкадо. - Понятия не имею, о чем .
