Researchers have found evidence for antibiotic resistance in the gut microbiomes of lemurs living close to humans. The more human contact they have, the more antibiotic resistance there is. Even capti...
Isoprene is the most abundant non-methane biogenic volatile organic compound (BVOC), but the processes governing secondary organic aerosol (SOA) formation from isoprene oxidation are only beginning to...
Genomic distance between two genomes, i.e., the smallest number of genome rearrangements required to transform one genome into the other, is often used as a measure of evolutionary closeness of the ge...
We prove a Central Limit Theorem for the proportion of infected individuals for an epidemic model by dealing with a discrete time system of simple random walks on a complete graph with n vertices. Ea...
In this paper, a new estimator of the population proportion has been proposed by using moment generating function and compared with the usual estimator from the minimum mean squared error point of vie...
An in vitro experiment was carried out to investigate effects of solid associated (SAB) and liquid associated bacteria (LAB) and the type of incubation substrate on ruminal fermentation and gas produc...
Chromosome analysis of Clarias lazera living in wet lands located in Göksu River (Göksu Delta) was accomplished by modified air-drying. Clarias lazera was found to have 18 metacentric, 26 su...
In alkaline media and at 70°C dilute suspensions of ferrihydrite transformed to goethite between pH 11.2 and 14 and to a mixture of goethite and hematite above and below this pH range. Increasing the ...
Until now, the different attempts to describe the defects of kaolinites were based on the ideas that (i) the hkl reflections with k = 3n are Bragg reflections, while (ii) the hkl reflections with k ≠ ...
