Übersetzung für "Chemische einwirkung" in Englisch

Such changes are produced through exposure to mechanical, thermal, chemical or enzymatic factors.

In this let us not forget that such a chemical reaction is quite prolonged.

The foam formation process is started with chemical propellant under the influence of temperature.

Dense foam allows to optimize the chemical cleaning and sanitizing action.

Certain physical or physical-chemical cell characteristics survive the action of proteolytic enzymes substantially more reliably than immunologically identifiable cell properties.

The original shall be drawn up on such paper as shall show up any tampering by mechanical or chemical means.

An injury is a bodily lesion resulting from acute exposure to energy (mechanical, thermal, electrical, chemical or radiant) or from an insufficiency of a vital element (drowning, strangulation or freezing).

At the same time, the chemical effect of the non-bio-active prosthesis material on the bone tissue and hence the danger of foreign body reaction is reduced.

OBJECTS AND SUMMARY OF THE INVENTION The object of the invention is to improve the mechanical pressing properties of wet pulp in the sugar industry by chemically acting on the cell structure substances and to decrease thereby the energy consumption in the ensuing thermal drying without diminishing the economy and the quality of sugar extraction and sugar isolation.

But it is possible, without anything further, to use fabrics embodying fibers whose surface has been activated and roughened beforehand by chemical action.

This objective is met with a coated fabric which consists according to the invention of a woven fabric of continuous multifilament threads whose surface, to improve adhesion, has been chemically activated and roughened, the fabric having a weaving density ranging between 26% and 60%, as well as a first and second coating composed of a plastic/synthetic resin mix, whereby the proportion by weight of the two components of the mix varies in both coatings.

The luminescent particles are excited by means of radiation with light, ultraviolet, x-rays, gamma or corpuscular beams, or, alternatively, by chemical processes, through the application of electric fields or electrical discharge processes. They emit light, infrared or ultraviolet radiation when returning to their original state.

Resistance to chemical action and to solvents (e.g., n-pentane, gasoline, lyes and acids) is substantially improved.

OBJECTS AND SUMMARY OF THE INVENTION The object of the invention is to improve the mechanical pressing properties of wet pulp in the sugar industry by chemically acting on the cell structure substances and to decrease thereby the energy consumption in the ensuing thermal drying without diminishing the economy and the quality of sugar extraction and sugar isolation.

By variations of the Al content, the energy gap of the material and thereby its luminescence properties and its resistance to chemical attack are affected.

At this point in time, a further chemical action of the polishing agent on the semiconductor wafer is damaging and must be stopped as rapidly as possible. This damage can be stopped, for example, by transferring the semiconductor wafer into a washing, neutralization or cleaning bath.

It has surprisingly now been found that aqueous copolymer dispersions prepared in accordance with AT-B 402 504 by a two-stage process in which monomers having in each case carbonyl and carboxyl groups are employed only in the first stage (which leads to the core of the particles) can be crosslinked, following neutralization of the carboxyl groups by adding small amounts of ammonia, amines or aqueous alkalis, with polyfunctional hydrazides and lead to binders having a sufficient pot life which can be processed to give coating materials having high film hardness, good resistance to mechanical and chemical exposure, rapid drying, and little or no tendency to yellow.

These open cells can be further multiplied by inventively opening the thin shells of individual hollow microspheres by mechanical and/or chemical means, so that individual hollow microspheres thereby also form open cells.

This feature of the method has the advantage that in addition to the thermal action a chemical action also takes place.

It can be changed by bending, wear or chemical attack to its surface, or by soiling with soot particles.

While paper-impregnated cables are particularly susceptible to external chemical and thermal influences, in high-voltage PE or XLPE cables the polyethylene insulation of the conductor is affected, leading to partial breakdowns and cracks that “eat away” the insulation.

Different methods, such as corona processes, flame treatment or plasma treatment and the chemical action of ozone or fluorine increase the surface free energy and therefore ensure improved wetting, initial adhesion and long-term stability.

During this period there is a formation of bodies and TsNS of an embryo therefore chemical impact on its organism can lead to sad consequences.

Persons working in the local environment of specific parts of such plants can be exposed to considerable risks during operation, such as collision, crushing, other mechanical, thermal or chemical effects or radiation for example.

This is done, for example, by radiation from outside with UV light, another radiation or ultrasound or by a chemical effect either by addition of a suitable substance starting a reaction at the conveying elements or at the pump housing or by reaction with a substance which is anyway in the blood to be conveyed and which acts as a reaction partner or as a catalyst.

Examples of specific embodiments of a triggering mechanism are casing substances which can be changed through heat, through mechanical, electrical or chemical action or through irradiation.

The properties of the water-based cooling lubricants with dispersed oil-based droplets can also be degraded by mechanical, biological, or chemical effects.

Immobilization in the meaning of the invention involves various methods of fixing the agents according to the invention, which can be achieved particularly by exposure to biological, chemical or physical action.
