Experimental acute otitis media was produced by injecting various agents into the middle ear cavity of the guinea-pig and the animal was sacrificed for histological studies after 7 days of careful observation. The results are summarized as follows: 1) The introduction of bacteria suspension, egg albumin or milk into the healthy middle ear cavity produced the proliferation of the connective tiss...

In a population of size N , adaptive evolution is 2N times faster under Mendelian inheritance than under the 19th-century theory of blending inheritance. Unfortunately we have no means of determining, according to the standard of years, how long a period it takes to modify a species. Charles Darwin [2, p. 270] In the latter half of the 19th century, evolutionary time seemed limited. Victorian s...

earliness and drought escape are as a primary strategy for plant adaptation in regions that plants are subjected to terminal drought stress. plants react to drought through morphological changes and alteration in physiological behavior. accordingly, two separate experiments to assess the response of yield and morphophysiological characteristics of earliness chickpea genotypes to drought stress ...

The paper presents a concept of dynamic bulk density estimation of a particulate matter stream using a 3-d image analysis system and a conveyor belt scale. A method of image acquisition should be adjusted to the type of scale. The paper presents some laboratory results of static bulk density measurements using the MS Kinect time-of-flight camera and OpenCV/Matlab software. Measurements were mad...

Antioxidant activity of methanolic extract of Drynaria quercifolia rhizome at different concentrations (100, 200 and 300μg/ml) were studied in various in vitro models. Results were compared with standard ascorbic acid. Antioxidant activity of extract was increased with the increasing concentration. The order of antioxidant potential according to models were found to be highest in nitric oxide s...

Many applications in modern biotechnology require a rapid and sensitive prediction of hybridization or partial hybridization between an oligonucleotide and potential targets in a genomic DNA or mRNA database. In addition, the accurate prediction of melting profiles between an oligonucleotide and a target nucleic acid is also of great value. DNA and RNA chip technologies [16, 17], PCR primer des...

Query Optimization is to use the best plan for the query that improves the performance of the query. Query Optimization is difficult in distributed databases as compared to centralized databases. Queries in distributed databases are effected by factors such as insertion methods of the data into the remote server and transmission time between servers. Response time of the query depends upon the ...
