| the arabs and the science of population distribution. | before the establishment of demography as a scientific discipline, arab writers had developed and utilized demographic principles in their scientific writings about geography. early arab advances in demographic thought, especially in regard to population distribution, were discussed. (all dates were given as anno hegira (ah), i,e., the dates accord with the muslim calendar in which the 1st year coincides with mohammed's flight from mecca in 622). as early as the 2nd century hegira, a number of ... | 1982 | 12266315 |
| the effect of labor migration on relations of exchange and subordination among the rashaayda bedouin of sudan. | this study is based on qualitative data gathered during 3 years of fieldwork among the rashaayda, arabic-speaking pastoralists in sudan. prior to 1956, every rashiidy household was linked to other households by 3 types of social relations: 1) patrilineal descent, 2) co-residence, and 3) incorporation by purchase. after 1956, "slaves" retained membership in the tribe, but were not economically dependent on "free owners" and lived apart from "free" rashaayda. yet most rashaayda sought aid from ... | 1987 | 12281017 |
| biased parental investment and reproductive success in gabbra pastoralists. | this study of wealth and reproductive success is based on interviews obtained from 848 rural nomadic gabbra families from northern kenya. the gabbra are nomadic pastoralists who herd camels, goats, and sometimes sheep. household is defined as a unit that owns a camel herd. findings indicate that size of the camel herd (wealth) is positively related to the reproductive success of both men and women and is independent of age. the effect is greatest for men. poverty effects vary between men an ... | 1996 | 12292074 |
| enteric coronavirus infection in a juvenile dromedary (camelus dromedarius). | a case of an enteric coronavirus infection in a 6-week-old dromedary calf is described. the animal had diarrhea for 5 days and died despite symptomatic treatment. numerous viral particles, approximately 140 nm in diameter, with club-like projections were detected in the feces by electron microscopy. these characteristics were consistent with a coronavirus. immunohistochemical reactivity with 2 antigenic group ii coronavirus-specific antibodies confirmed the presence of viral antigen in colonic e ... | 2002 | 12296403 |
| an old balancing act: resources v. population. | population concern is found not only among modern man, but among primitive peoples and animal groups. although some researchers object to extrapolating from animal behavior to human behavior, it is still an oft-observed fact that crowding produces fighting, territorial aggression, or other behaviors which disperse the population and relieve the pressures on food and other resources. female chimpanzees bear offspring at 5-year intervals although they come into estrus yearly. this may be due t ... | 1977 | 12308844 |

| cd4+ th2 cell recognition of hla-dr-restricted epitopes derived from camel: a tumor antigen translated in an alternative open reading frame. | tumor ag ny-eso-1 is an attractive target for immunotherapy of cancer, since both cd8(+) ctl and cd4(+) th cells against ny-eso-1 have been described. moreover, ny-eso-1 as well as the highly homologous tumor ag lage-1 are broadly expressed in various tumor types. interestingly, the ny-eso-1 and lage-1 genes also encode for proteins translated in an alternative open reading frame. these alternatively translated ny-eso-orf2 and camel proteins, derived from the ny-eso-1 and lage-1 genes, respectiv ... | 2003 | 12538712 |
| emergence and evolution of functional heavy-chain antibodies in camelidae. | antibodies of jawed-vertebrates are composed of paired heavy (h) and light (l) polypeptide chains. surprisingly, the sera of camelids, nurse shark and wobbegong shark, and possibly ratfish contain antibodies that lack l-chains. in camelids, these heavy-chain antibodies (hcabs) are gamma-isotypes, and are functional in antigen binding. in this review we focus on the dedicated immunoglobulin (ig) genes that encode the hcab in camelidae (camels, dromedaries and llamas), about their origin, and how ... | 2003 | 12543123 |
| hybrid monte carlo with multidimensional replica exchanges: conformational equilibria of the hypervariable regions of a llama vhh antibody domain. | since the structural repertoire of the hypervariable regions of human antibodies is known to be more restricted than what is implied by sequence variability, a common approach to structural prediction is to use a knowledge-based (kb) method, such as the canonical structure model (c. chothia and a. m. lesk, journal of molecular biology, 1987, vol. 196, pp. 901-917). however, this model is less successful when applied to camelid heavy chain antibodies. in this study, molecular simulations were use ... | 2003 | 12548621 |
| less impairment in face imagery than face perception in early prosopagnosia. | there have been a number of reports of preserved face imagery in prosopagnosia. we put this issue to experimental test by comparing the performance of mjh, a 34-year-old prosopagnosic since the age of 5, to controls on tasks where the participants had to judge faces of current celebrities, either in terms of overall similarity (of bette midler, hillary clinton, and diane sawyer, whose face looks least like the other two?) or on individual features (is ronald reagan's nose pointy?). for each task ... | 2003 | 12559160 |
