In developing countries, where a majority of families derive their livelihoods from agriculture, sustainable agriculture cannot be discussed in isolation of sustainable rural livelihoods. Sustainable rural livelihood is a multifaceted concept and refers to maintenance or enhancement of access of rural families to food and income-generating activities on a long-term basis. It encompasses secured...

Variations in somato-genetic patterns in muscle-fibre biology, biochemical metabolic pathways and pulmonary physiology are hypothesized to have been concentrated by natural selection over the centuries in the Afrocentric peoples displaced from West Africa to the New World. These phenotypic and genotypic characteristics are attributed to provide the athletic prowess so well documented in African...

Lipid components of [Pseudomonas] echinoides NCIMB 9420 have been studied as an aid to taxonomic relocation of the organism. Non-polar lipids include the carotenoid nostoxanthin and the ubiquinone Q-10. The major fatty acids are cis-vaccenic acid [18:1(11c)], hexadecanoic acid (16:0) and 2-hydroxy-tetradecanoic acid (2-OH-14:0), but 11-methyloctadec-11-enoic acid[11-Me-18:1(11)] is a significan...

The wild-type strain Streptomyces ambofaciens DSM 40697 exhibits a high degree of genetic instability. Pigment-defective colonies were observed in the progeny of wild-type colonies at a frequency of about 0.01. While only 13% of these pigment-defective colonies gave rise to homogeneous progeny exhibiting the mutant parental phenotype, 87% of the mutant colonies gave rise to hetergeneous progeny...

the present paper is an attempt to apply bourdieu’s field theory to the political field of the islamic republic of iran. the concept of field, as explained by bourdieu, provides a suitable theoretical framework to identify and explain the complexities and intricacies of different behaviors of this system and analyze its absolutely different practices in domestic and international arenas.  the m...

one of the chapters in the history of iranian music is the place and significance of the musical instrument called oud. this instrument, initially named “barbat”, emerged during the sassanid dynasty. generally known under the name “oud” in islamic era, it became grepopular in islamic countries. in iran, this instrument enjoyed great importance until the fall of the safavid dynasty. from the ear...

*Corresponding Address: LC Nnaji [email protected] In view of the fundamental role of antioxidants such as beta carotene in human nutrition, this study was designed to determine the concentrations of this antioxidant in chicken egg yolks of the preponderant poultry breeds in Nigeria. Among the strains studied include Harco, White Leghorn, and Local chickens. Again, due to instability...

The majority of early-onset cases of familial Alzheimer's disease (FAD) are linked to mutations in two related genes, PS1 and PS2, located on chromosome 14 and 1, respectively. Using two highly specific antibodies against nonoverlapping epitopes of the PS1-encoded polypeptide, termed presenilin 1 (PS1), we document that the preponderant PS1-related species that accumulate in cultured mammalian ...

The ERP (event-related potential) violation paradigm was used to investigate brain responses to morphologically correct and incorrect verb forms of Catalan. Violations of stem formation and inflectional processes were examined in separate experimental conditions. Our most interesting finding is that misapplications of stem formation rules elicit an early left preponderant negativity. This compl...

• Multiple electrical recordings from the thoracic surface of the dog have recently shown that during some portions of the QRS interval only one maximum and one minimum of potential are simultaneously present on the chest wall, as one would expect from the theory of the single equivalent dipole. During larger portions of the ventricular depolarization time, however, several simultaneous maxima ...
