chlorinated hydrocarbon
A class of persistent, broad-spectrum insecticides that linger in the environment and accumulate in the food chain. Among them are DDT, aldrin, dieldrin, heptachlor, chlordane, lindane, endrin, mirex, hexachloride, and toxaphene. In insects and other animals these compounds act primarily on the central nervous system. They also become concentrated in the fats of organisms and thus tend to produce fatty infiltration of the heart and fatty degeneration of the liver in vertebrates. In fishes they have the effect of preventing oxygen uptake, causing suffocation. They are also known to slow the rate of photosynthesis in plants. Their danger to the ecosystem resides in their rate stability and the fact that they are broad-spectrum poisons which are very mobile because of their propensity to stick to dust particles and evaporate with water into the atmosphere.

7 Colours
Not all English colour terms have a single exact equivalent in French: for instance, in some circumstances brown is marron, in others brun. If in doubt, look the word up in the dictionary.Colour termswhat colour is it?= c’est de quelle couleur? or (more formally) de quelle couleur est-il?it’s green= il est vert or elle est verteto paint sth green= peindre qch en vertto dye sth green= teindre qch en vertto wear green= porter du vertdressed in green= habillé de vertColour nouns are all masculine in French:I like green= j’aime le vertI prefer blue= je préfère le bleured suits her= le rouge lui va bienit’s a pretty yellow!= c’est un joli jaune!have you got it in white?= est-ce que vous l’avez en blanc?a pretty shade of blue= un joli ton de bleuit was a dreadful green= c’était un vert affreuxa range of greens= une gamme de vertsMost adjectives of colour agree with the noun they modify:a blue coat= un manteau bleua blue dress= une robe bleueblue clothes= des vêtements bleusSome that don’t agree are explained below.Words that are not true adjectivesSome words that translate English adjectives are really nouns in French, and so don’t show agreement:a brown shoe= une chaussure marronorange tablecloths= des nappes fpl orangehazel eyes= des yeux mpl noisetteOther French words like this include: cerise ( cherry-red), chocolat ( chocolate-brown) and émeraude ( emerald-green).Shades of colourExpressions like pale blue, dark green or light yellow are also invariable in French and show no agreement:a pale blue shirt= une chemise bleu pâledark green blankets= des couvertures fpl vert foncéa light yellow tie= une cravate jaune clairbright yellow socks= des chaussettes fpl jaune vifFrench can also use the colour nouns here: instead of une chemise bleu pâle you could say une chemise d’un bleu pâle ; and similarly des couvertures d’un vert foncé (etc). The nouns in French are normally used to translate English adjectives of this type ending in -er and -est:a darker blue= un bleu plus foncéthe dress was a darker blue= la robe était d’un bleu plus foncéSimilarly:a lighter blue= un bleu plus clair (etc.)In the following examples, blue stands for most basic colour terms:pale blue= bleu pâlelight blue= bleu clairbright blue= bleu vifdark blue= bleu foncédeep blue= bleu profondstrong blue= bleu soutenuOther types of compound in French are also invariable, and do not agree with their nouns:a navy-blue jacket= une veste bleu marineThese compounds include: bleu ciel ( sky-blue), vert pomme ( apple-green), bleu nuit ( midnight-blue), rouge sang ( blood-red) etc. However, all English compounds do not translate directly into French. If in doubt, check in the dictionary.French compounds consisting of two colour terms linked with a hyphen are also invariable:a blue-black material= une étoffe bleu-noira greenish-blue cup= une tasse bleu-verta greeny-yellow dress= une robe vert-jauneEnglish uses the ending -ish, or sometimes -y, to show that something is approximately a certain colour, e.g. a reddish hat or a greenish paint. The French equivalent is -âtre:blue-ish= bleuâtregreenish or greeny= verdâtregreyish= grisâtrereddish= rougeâtreyellowish or yellowy= jaunâtreetc.Other similar French words are rosâtre, noirâtre and blanchâtre. Note however that these words are often rather negative in French. It is better not to use them if you want to be complimentary about something. Use instead tirant sur le rouge/jaune etc.To describe a special colour, English can add -coloured to a noun such as raspberry (framboise) or flesh (chair). Note how this is said in French, where the two-word compound with couleur is invariable, and, unlike English, never has a hyphen:a chocolate-coloured skirt= une jupe couleur chocolatraspberry-coloured fabric= du tissu couleur framboiseflesh-coloured tights= un collant couleur chairColour verbsEnglish makes some colour verbs by adding -en (e.g. blacken). Similarly French has some verbs in -ir made from colour terms:to blacken= noircirto redden= rougirto whiten= blanchirThe other French colour terms that behave like this are: bleu (bleuir), jaune (jaunir), rose (rosir) and vert (verdir). It is always safe, however, to use devenir, thus:to turn purple= devenir violetDescribing peopleNote the use of the definite article in the following:to have black hair= avoir les cheveux noirsto have blue eyes= avoir les yeux bleusNote the use of à in the following:a girl with blue eyes= une jeune fille aux yeux bleusthe man with black hair= l’homme aux cheveux noirsNot all colours have direct equivalents in French. The following words are used for describing the colour of someone’s hair (note that les cheveux is plural in French):fair= blonddark= brunblonde or blond= blondbrown= châtain invred= rouxblack= noirgrey= griswhite= blancCheck other terms such as yellow, ginger, auburn, mousey etc. in the dictionary.Note these nouns in French:a fair-haired man= un blonda fair-haired woman= une blondea dark-haired man= un bruna dark-haired woman= une bruneThe following words are useful for describing the colour of someone’s eyes:blue= bleulight blue= bleu clair invlight brown= marron clair invbrown= marron invhazel= noisette invgreen= vertgrey= grisgreyish-green= gris-vert invdark= noir -
8 Usage note : might
Although usage shows that may and might are interchangeable in many contexts, might indicates a more remote possibility than may. French generally translates this element of possibility using peut-être with the appropriate verb tense:it might snow= il va peut-être neiger(It is also possible to translate this more formally using il se peut + subjunctive: il se peut qu’il neige). For particular examples see might1 1.It is possible to translate might differently depending on the nature of the context and the speaker’s point of view:he might not come= il risque de ne pas venirimplies that this is not a desirable outcome for the speaker ;he might not come= il pourrait ne pas venir or il se peut qu’il ne vienne pashowever, is neutral in tone. Where there is the idea of a possibility in the past which has not in fact occurred (see might1 2), French uses the past conditional of the verb (which is often pouvoir):it might have been serious (but wasn’t in fact)= ça aurait pu être graveThis is also the case where something which could have taken place did not, thus causing annoyance:you might have said thanks!= tu aurais pu dire merci!(see might1 7).might, as the past tense of may, will automatically occur in instances of reported speech:he said you might be hurt= il a dit que tu serais peut-être blesséFor more examples see the entry might1 and bear in mind the rules for the agreement of tenses.Where there is a choice between may and might in making requests, might is more formal and even rather dated. French uses inversion (je peux = puis-je?) in this context and puis-je me permettre de…? (= might I…?) is extremely formal.Might can be used to polite effect - to soften direct statements: you might imagine that…or to offer advice tactfully: it might be wise to…In both cases, French uses the conditional tense of the verb: on pourrait penser que… ; ce serait peut-être une bonne idée de… The use of well in phrases such as he might well be right etc. implies a greater degree of likelihood.For translations of might well, may well, see B2 in the entry well1. -

courant (permanent) admissible, m
valeur maximale du courant électrique qui peut parcourir en permanence, un conducteur, un dispositif ou un appareil, sans que sa température de régime permanent, dans des conditions données, soit supérieure à la valeur spécifiée
[IEV number 826-11-13]Ampacity, the term is defined as the maximum amount of current a cable can carry before sustaining immediate or progressive deterioration. Also described as current rating or current-carrying capacity, is the RMS electric current which a device can continuously carry while remaining within its temperature rating. The ampacity of a cable depends on:
- its insulation temperature rating;
- conductor electrical properties for current;
- frequency, in the case of alternating currents;
- ability to dissipate heat, which depends on cable geometry and its surroundings;
- ambient temperature.
Electric wires have some resistance, and electric current flowing through them causes voltage drop and power dissipation, which heats the cable. Copper or aluminum can conduct a large amount of current before melting, but long before the conductors melt, their insulation would be damaged by the heat.
The ampacity for a power cable is thus based on physical and electrical properties of the material & construction of the conductor and of its insulation, ambient temperature, and environmental conditions adjacent to the cable. Having a large overall surface area may dissipate heat well if the environment can absorb the heat.
In a long run of cable, different conditions govern, and installation regulations normally specify that the most severe condition along the run governs the cable's rating. Cables run in wet or oily locations may carry a lower temperature rating than in a dry installation. Derating is necessary for multiple circuits in close proximity. When multiple cables are near, each contributes heat to the others and diminishes the amount of cooling air that can flow past the individual cables. The overall ampacity of the insulated conductors in a bundle of more than 3 must be derated, whether in a raceway or cable. Usually the de-rating factor is tabulated in a nation's wiring regulations.
Depending on the type of insulating material, common maximum allowable temperatures at the surface of the conductor are 60, 75 and 90 degrees Celsius, often with an ambient air temperature of 30°C. In the U.S., 105°C is allowed with ambient of 40°C, for larger power cables, especially those operating at more than 2 kV. Likewise, specific insulations are rated 150, 200 or 250°C.
The allowed current in cables generally needs to be decreased (derated) when the cable is covered with fireproofing material.
For example, the United States National Electric Code, Table 310-16, specifies that up to three 8 AWG copper wires having a common insulating material (THWN) in a raceway, cable, or direct burial has an ampacity of 50 A when the ambient air is 30°C, the conductor surface temperature allowed to be 75°C. A single insulated conductor in air has 70 A rating.
Ampacity rating is normally for continuous current, and short periods of overcurrent occur without harm in most cabling systems. The acceptable magnitude and duration of overcurrent is a more complex topic than ampacity.
When designing an electrical system, one will normally need to know the current rating for the following:- Wires
- Printed Circuit Board traces, where included
- Fuses
- Circuit breakers
- All or nearly all components used
Some devices are limited by power rating, and when this power rating occurs below their current limit, it is not necessary to know the current limit to design a system. A common example of this is lightbulb holders.

food irradiation
The most recent addition to food preservation technologies is the use of ionizing radiation, which has some distinct advantages over conventional methods. With irradiation, foods can be treated after packaging, thus eliminating post-processing contamination. In addition, foods are preserved in a fresh state and can be kept longer without noticeable loss of quality. Food irradiation leaves no residues, and changes in nutritional value due to irradiation are comparable with those produced by other processes. Irradiation is the process of applying high energy to a material, such as food, to sterilize or extend its shelf-life by killing microorganisms, insects and other pests residing on it. Sources of ionizing radiation that have been used include gamma rays, electron beams and X-rays. Gamma rays are produced by radioactive isotopes such as Cobalt-60. Electron beams are produced by linear accelerators, which themselves are powered by electricity. The dose applied to a product is the most important factor of the process. At high doses, food is essentially sterilized, just as occurs in canning. Products so treated can be stored at room temperature almost indefinitely. Controversial and banned in some countries.
