Water pollution is increasing with rapidly growing industries and world population, which very harmful for marine life humans as well. This research has been conducted to introduce novel material advanced techniques the effective removal of heavy metals from wastewater. Successful nanofiber membranes have developed hemp charcoal (HC) polyacrylonitrile (PAN), can remove water efficiently in less...

During the past 3 yr, nematologists in the United States have found specimens of Bursaphelenchus sp. in the wood of dead and dying pine trees. This nematode-host association resembles a similar interaction reported from Japan where pine trees are being killed by the pine wood nematode. This taxonomic research was conducted to determine if the Japanese pine wood nematode and similar populations ...

Will Fischer, H. X. Liao, Barton F. Haynes, Norman L. Letvin, Bette Korber Nickle et al. [1] recently reported a computational method for HIV-1 vaccine antigen design; here we compare this method with our previously published vaccine antigen design method [2], using several criteria that we believe to be important for a successful vaccine candidate [2]. The intent of both approaches is to desig...

The J4 dispersal juvenile is a specialized life stage of the pinewood nematode, Bursaphelenchus xylophilus (Steiner &Buhrer) Nickle, that is transported by cerambycid beeries in the genus Monochamus. The nlediafion of J4 exit fronl beetle vectors is poorly understood. We hypothesized that decreasing neutral storage lipid in B. xylophilus J4 was related to behaviors leading to their exit from th...

Pinewood nematode, Bursaphelenchus xylophilus (Steiner &Buhrer) Nickle, spatial dispersion was determined in Scots pine, Pinus sylvestris L., bolts infested with the pine sawyer beetle, Monochamus carolinensis (Olivier) and in bolts without M. carolinensis. According to Taylor's power law and Green's index of dispersion, nematode dispersion was aggregated in both sets of bolts. The degree of ag...

NTRODUCTION The goals of root canal therapy are to remove infected and necrotic pulpal tissue remnants, shape the root canal system to facilitate irrigation and medication and adequate sealing using obturation materials. 1 Rotary instruments enhance the quality of obturation by providing conical shape to the root canal. Nickle titanium (NiTi) alloy instruments inherent flexibility that allows t...
