the genetic variation and diversity among fifty-eight polyvoltine silkworm genotypes was estimated by using ten economic traits. the results revealed that the single shell weight showed higher genetic variation such as pcv% (17.20%), gcv% (12.93%), and heritability (56.5%) followed by single cocoon weight, shell ratio and matured larval weight. the d2 (mahalonobis? distance) statistics revealed...

The maximum brightness of one of the prothoracic light organs of the West Indian elaterid beetles, Pyrophorus (measured at Princeton, New Jersey) was found to be .045 lambert, or .045 lumen per sq. cm. at 20 degrees C. This corresponds to .0002 candle for one organ, or .0004 candle for the pair of prothoracic organs.

In many scienti c and commercial applications such as Earth Observation System (EOSDIS) and mobile phone services tracking a large number of clients, it is a daunting task to archive and index ever increasing volume of complex data that are continuously added to databases. To eÆciently manage multidimensional data in scienti c and data warehousing environments, R-tree based index structures hav...

in order to evaluate the effect of humic acid and zn on the grape yield and mineral concentration, a factorial experiment was conducted based on a randomized complete block design with three replications. the study was done on 20 years old grapevines in the farsan region from chaharmahal and bakhtiari province in 2013-2014. each of the factors, humic acid and zinc sulfate, were applied in three...

introduction: the idea that factors during early critical periods of life affect on long term health is now a major public health concern. in this study, in addition to investigating obesity prevalence among female high school students in yazd, the relationship between obesity and birth weight was examined. materials and methods: this cross sectional study was conducted on 312 female high schoo...

Using recently calculated analytic models for the thermal structure of ultramagnetized neutron stars, we estimate the thermal fluxes from young (t ∼ 1000 yr) ultramagnetized (B ∼ 10 G) cooling neutron stars. We find that the pulsed X-ray emission from objects such as 1E 1841-045 and 1E 2259+586 as well as many soft-gamma repeaters can be explained by photon cooling if the neutron star possesses...

Thermal resistance and air permeability of needle-punched nonwoven fabric made from jute and polypropylene blends have been studied using the Box and Behnken factorial design to observe the effect of fabric weight, needling density and blend proportion on thickness, thermal resistance, specific thermal resistance, air permeability and sectional air permeability. Correlation matrix and cluster a...

Among the various clustering algorithms, DBSCAN is an effective clustering algorithm used in many applications. It has various advantages like no a priori assumption needed about the number of clusters, can find arbitrarily shaped clusters and can perform well even in the presence of outliers. However, the performance is seriously affected when the dataset size becomes large. Moreover, the sele...
