The pathogenesis of bluetongue in sheep: a study by immunofluorescence and histopathology
(1968)
The pathogenesis of bluetongue in sheep was studied by clinical and gross observations, immunofluorescence, histopathologic, and serum-virus neutralization techniques. Sheep were killed during a 16 day postinoculation ...
A cytogenetic study of differentiation between G. hirsutum and G. barbadense chromosomes using heterozygous translocations involving certain chromosomes of the A and D genomes
(1968)
The primary object of this study was to determine some of the difference at the chromosome level between the two tetraploid species, G. hirsutum and G. barbadense, which cross readily and the F₁ hybrid is fertile but the ...
A histological and ultrastructural study of the pathogenesis of toxic myopathies of avian striated muscle
(1968)
Toxic myodegeneration of avian striated muscle was studied by giving intraperitoneal injections of plasmocid[6-methoxy-8-(3-diethylaminopropylamino)quinolone] to 15 chickens and oral doses of ground Cassia occidentalis ...
Genetic studies in crosses between Sphacelotheca reiliana (Kühn) Clint. and S. sorghi (Lk.) Clint
(1968)
Interspecific crosses among haploid progenies from one teliospore of Sphacelotheca reiliana and one teliospore of S. sorghi were made. A high degree of compatibility was found among haploid lines of the two species. With ...
Petrology of the early Cretaceous Yucca Formation, southern Quitman Mountains and vicinity, Trans-Pecos Texas
(1968)
The Yucca Formation of Neocomian to Aptian age extends from the geosynclinal region of the Chihuahua Trough in Mexico, eastward to the Diablo Platform in Trans-Pecos Texas. At Quitman Gap, in the Quitman Mountains, the ...
Optimum packaging design and component sparing policies for extended manned space missions
(1968)
The primary objective of this research is to provide an analytical solution to the problem of optimizing the design of manned spacecraft systems with respect to the modular level at which on-board replacement of failed ...
