assimilation

[ə‚sim·ə′lā·shən]
(geology)
Incorporation of solid or fluid material that was originally in the rock wall into a magma.
(physiology)
The conversion of nutritive materials into protoplasm.

assimilation

(especially in race relations) the process in which a minority group adopts the values and patterns of behaviour of a majority group or host culture, ultimately becoming absorbed by the majority group (compare ACCOMMODATION). The process can involve changes for both the majority and the minority groups. It may prove more difficult to accomplish where visible signs (e.g. clear-cut distinctions of‘colour’) form the basis of the original division (e.g. in the US ‘melting pot’, the assimilation of black minority groups).

Assimilation

 

in physiology, the living organism’s utilization of food for the expenditure of energy and for restorative body functions. Complex food substances are assimilated after being broken down into simple compounds by the digestive enzymes. The effective degree of assimilation is determined by the difference between the body’s alimentary intake of proteins, fats, and carbohydrates and the end products resulting from their breakdown. The important factor in assimilation is not the absolute degree of digestibility but the rate at which food substances are digested, which may limit subsequent absorption.

The degree of assimilation depends on the nutritional regimen, food content, method of culinary preparation, and gastrointestinal tract functioning. The capacity to assimilate is lowered when the nutritional regimen is disrupted or when the stomach is overloaded with large quantities of food. Animal food products are assimilated more completely than vegetable products. The human body assimilates 92 to 96 percent of the proteins of animal origin, 46 to 70 percent of those from vegetables, 98 percent of the carbohydrates, and 95 percent of the fats ingested. The physiological value of food is largely determined by its assimilability, which must be taken into account in establishing nutritional norms. Unassimilable food substances, and especially cellulose, play an essential part in the movements of the intestine.

Most of the observations being assimilated are in a northwest-to-southeast strip through the center of the domain (Figure 2), and since the entire 1 km domain is 188 km across, the time for air affected by the TAMDAR observations to be advected out of the domain will be somewhat limited.
The assimilated shape was the least prevalent in our study and also in most studies reported in the literature, including Thai, Turkish and South Indian populations (Tuli et al.; Kositbowornchai et al.; Jansisyanont et al.; Murlimanju et al.; Shenoy et al.; Lavanya Varma & Sammer; Sekerci & Sisman) (Table I).
Even when obtained from lean food sources, the problem with excess protein consumption is that the surplus cannot be stored or assimilated. It is oxidized and used for energy, converted to fat, or excreted.
While such a movement may be difficult to explain from a picture of a strictly assimilated German Jewry, it becomes far less surprising in view of Mendes-Flohr's more contoured analysis of the German-Jewish encounter as an "inner Jewish dialogue." Already in 1916, with the publication of Martin Buber's journal Der Jude, many German Jews entered a new phase in the dialectical encounter with German culture.
The respiratory losses of [sup.14]C [CO.sub.2] after 7 and 35 days were calculated as the difference between total recoveries of assimilated [sup.14]C after these periods and the recoveries after 4 h.
According to the professional groups, the basic and allied engineering professions assimilated the largest number of expatriate workers till the end of June 2015.
In his earlier paintings and murals, the Berlin artist, born in 1966, had already assimilated the Pop aesthetic: Sports-car chassis and electronic gadgets or rumpled jeans and hands with painted fingernails were combined with citations from art of the last forty years--a few streaks of color a la Morris Louis here, cool graphics reminiscent of James Rosenquist there, all delicately layered.
Yancey draws from the work of Milton Gordon and his theorizations of structural, marital, civic, and identificational assimilation to explore how readily minority groups can become assimilated into the dominant society, identify with majority group status, and adopt social attitudes that benefit dominant group members.
The underlying assumption of the government of this period was that the American Indians were to be assimilated into the American culture of individual property, agrarian production and Christianity.
Muslims, on the other hand, are far less likely to be assimilated. The Koran and the Bible are worlds (and civilizations) apart.
Instead, farm people assimilated these technologies into existing social patterns, which expanded to some extent" (p.
Orestes Brownson, in an 1884 essay titled "Native Americanism," wrote that the Irish and all other immigrants "must ultimately lose their own nationality and become assimilated in general character to the Anglo-American race." A convert, he insisted that a person could be both a good American and a good Catholic.
