Vacuum distillation is a technique that uses a vacuum to extract analytes from a sample. A condensing column is used in the technique to condense water that may also be present in the sample. A cryogenically cooled trap (cryotrap) is used to condense the compounds of interest. During a vacuum distillation procedure a sample is evacuated to a low pressure vaporizing volatile compounds, including water. The condenser column retains vaporized water and those vaporized compounds that are not condensed in the column are frozen in the cryotrap. 3, record 4, English, - condensation%20column

Dans la colonne montante, a lieu la principale phase d’oxygénation. L'air est introduit par un tuyau perforé(sparger). À la partie supérieure, elle communique avec une canalisation horizontale munie d’une ouverture permettant la sortie du gaz effluent. A l'entrée du compartiment descendant une réinjection d’air est faite. Elle provoque une augmentation de la vitesse de circulation vers le bas, dans la partie où est placé l'échangeur de chaleur de façon à obtenir un bon coefficient d’échange thermique. 1, record 7, French, - fermenteur%20%C3%A0%20boucle%20externe

In a distribution with two variates, the distribution of one of the variates when the other one is fixed. There are, for each variate, as many conditional distributions as there are values or classes for the other variate. A conditional distribution is expressed by indicating the variate to which it applies and the value or class fixed for the other variate: for example, conditional distribution of the variate Y given X = x. Conditional distributions of absolute frequencies are read directly in the rows and columns of the two-way table of frequencies. The conditional distributions of relative frequencies are obtained by dividing the numbers in each row (or column) by the total number in the relevant row (or column). The idea of a conditional distribution may be extended when the number of variates is greater than two. The conditional distributions are then the distributions of one or more variates when the other variate or variates are given. 1, record 10, English, - conditional%20distribution

Dans une distribution à deux variables, distribution de l'une des variables lorsque l'autre est fixée. Il y a, pour chaque variable autant de distributions conditionnelles qu'il y a de valeurs ou classes pour l'autre variable. Une distribution conditionnelle se désigne en indiquant la variable à laquelle elle s’applique et la valeur ou la classe fixée pour l'autre variable : par exemple, distribution conditionnelle de la variable Y pour X=x. Les distributions conditionnelles des effectifs se lisent directement dans les lignes et les colonnes du tableau à double entrée des effectifs. Les distributions conditionnelles des fréquences s’obtiennent en divisant les effectifs de chaque ligne(ou colonne) par l'effectif total de la ligne(ou colonne). La notion de distribution conditionnelle s’étend à un nombre de variables supérieur à deux. Les distributions conditionnelles sont alors des distributions à une ou plusieurs variables, l'autre ou les autres variables étant fixées. 2, record 10, French, - distribution%20conditionnelle
