TL;DR: The genetic analysis suggested that plant height, sympodia per plant, staple length and fibre strength could be improved through sib family, pedigree and progeny selection, while exploitation of heterosis would be necessary to attain the genetic advancement in monopodiaper plant, number of bolls, lint percentage and seed cotton yield.
Abstract: Five cotton cultivars were crossed in a complete diallel to study the inheritance of different polygenic traits. Genotypic differences were found to be significant (P<0.01) for all the characters. Adequacy tests disclosed that data of all the parameters were fully adequate for genetic analysis except bolls per plant, staple length, fibre strength, and fibre fineness, which was partially or not adequate. Additive component of genotypic variation (D) was significant and predominant for plant height, sympodia per plant, staple length and fibre strength, while dominance effects (H 1 and H 2) were main controlling factors for of monopodia per plant, number of bolls, lint percentage and seed cotton yield. More dominant genes were revealed in the parents for sympodia per plant, lint percentage and seed cotton yield. The values of H 2/4H 1 demonstrated asymmetrical and unequal distribution of dominant genes in the parents for all characters. Plant height, sympodia per plant, staple length and fibre strength exhibited high narrow sense heritability (h 2 n.s) due to the presence of additive gene action, whereas, monopodia per plant, number of bolls, lint percentage and seed cotton yield possessed low heritability. The genetic analysis suggested that plant height, sympodia per plant, staple length and fibre strength could be improved through sib family, pedigree and progeny selection, while exploitation of heterosis would be necessary to attain the genetic advancement in monopodia per plant, number of bolls, lint percentage and seed cotton yield.

TL;DR: Serum progesterone and estradiol-17β levels were estimated in Nili Ravi buffaloes with and without fetal membranes retention in three agro-ecological zones of Punjab and showed that serum progesterONE concentration was significantly higher than other levels.
Abstract: Serum progesterone and estradiol-17β levels were estimated in Nili Ravi buffaloes (n=190) with and without fetal membranes retention in three agro-ecological zones of Punjab. The results showed that serum progesterone concentration was significantly higher (P 0.05) significantly from each other.

TL;DR: This paper proposes a class-based priority scheme which classifies users' requests into high and low priorities and believes that assigning such priorities at multiple service levels can improve the performance of Web portals' requests of higher priority.
Abstract: Web portals work as a point of access to a large volume of information on the web. This paper focuses on the performance of Web portals in an E-commerce environment which involves the processing of a large number of users' requests. It proposes a class-based priority scheme which classifies users' requests into high and low priorities. In E-commerce, some requests (e.g.\ buy) are generally considered more important than others (e.g.\ search or browse). We contend that the requests received from a Web portal should generally get higher priority as such requests are more likely to lead to purchases. We believe that assigning such priorities at multiple service levels can improve the performance of Web portals' requests of higher priority. The proposed scheme is formally specified and implemented, and performance results are obtained and compared to a server that does not prioritise requests. The results show significant performance improvements in the processing of high priority requests.

TL;DR: A new approach, called the Oea framework, is introduced that will allow JavaScript developers to write programs using a class-based style, which is easy to use, has a syntax style that resembles that of the Java class- based approach and has high performance and reliability.

TL;DR: In order to investigate the performance of priority protocols in an eCommerce system, it is found that the interaction between the clients and the server is an important factor in the performance the protocols.
Abstract: In order to investigate the performance of priority protocols in an eCommerce system, we simulate their behaviour when composed with clients with differing behaviour. As suspected, we find that the interaction between the clients and the server is an important factor in the performance of the protocols.
