using the mixed solvents, (water +ethanol + propanol), the solubility of cdf2 was determined byevaporating method at 25° c. the results showed that the sollbility, s, of cdf2 decreases bydecreasing the dielectric constant of the mixed solvent .once the solubility of cdf2 was determined,the concentration solubility product, ksp(c)=4s3, was calculated .furthermore ,by estimating the meanactivity ...

potato virus y (pvy) is one of the most important pathogenic agents that reduce the yield and quality of tobacco (nicotiana tabacum l.). dna-based molecular markers are valuable tools for identifying germplasm in gene banks, assessing kinship ties, and doing marker-assisted selection (mas) for resistance to pests, diseases, and some crop traits of interest. this work presents the results of ass...

introduction: to protect genomes of all organisms from internal and external damages and maintain the genome integrity and the continuity of life, repair system has been developed in all living cells. defects in repair system are responsible for various kinds of disease including cancers and neurodegenerative diseases such as multiple sclerosis (ms). the relationship between various components ...

morphological and rapd markers were used to investigate the genetic diversity among 21 accessions of pomegranate originating from south eastern tunisia. thirteen morphological traits were studied and results showed significant differences for all morphological characters (p< 0.001). clustering based on fruit traits, using ward’s method, divided the accessions into three main groups. in rapd ana...

association analysis is a useful method for evaluation of significant association between molecular marker and phenotype of trait. this study was performed to evaluate association between traits related with powdery mildew resistance and molecular markers. this investigation was performed using 77 barley genotypes and aflp markers. in phenotypic evaluation, reaction of seedlings to powdery mild...

prophet of pou1f1 (prop1) plays direct or indirect important roles in the morphogenesis of pituitary gonadotropes as well as lactotropes, somatotropes and caudomedial thyrotropes. it also controls the expression of growth hormone, prolactin and thyrotropin subunits through regulatory pit1 factor. these hormones have important influences on production traits in most animal species including the ...

(1) Royal Military Academy, Brussels, Belgium (2) University of California, San Diego, USA Ballistocardiography (BCG) is a technique that had a large interest in cardiology between the fifties and eighties. Typically BCG consisted in the recording of mechanical acceleration (Acc), caused by cardiac activity, on a subject lying on a table. As Acc was recorded only in the 2-dimensions (2D) of the...
