abstract rice can be cultivated in various soils but soil with heavy texture and low permeability is more appropriate for its growth than other types of soil texture. it’s assumed that existence of zeolite in soil can be effective for moisture retention and avoiding of occurrence of crack in soil. in order to investigation of the effect of zeolite on moisture status and hydraulic properties of ...

BACKGROUND Little is known about oral health related to electronic-cigarette (EC) use, even though EC use is increasing rapidly. The aim of this study is to assess the relationship between EC use and oral health, including 'gingival pain and/or bleeding', 'tongue and/or inside-cheek pain', and 'cracked or broken teeth' among adolescents. METHODS A total of 65,528 students in 2016 were include...

Differences in stored-product psocid progeny production as a function of commodity type, percentage of cracked kernels, and wheat class were examined using laboratory bioassays. Population growth of Liposcelis bostrychophila Badonnel, Liposcelis decolor (Pearman), Liposcelis paeta Pearman, and Liposcelis entomophila (Enderlein) (Psocoptera: Liposcelididae) was highest on sorghum Sorghum bicolor...

BACKGROUND Atrophic gastritis can be classified according to characteristic mucosal patterns observed by Blue LASER Imaging (BLI) in a medium-range to distant view. AIMS To facilitate the endoscopic diagnosis of Helicobacter pylori (HP)-related gastritis, we investigated whether atrophic mucosal patterns correlated with HP infection based on the image interpretations of three endoscopists bli...

DRDC Valcartier is actively working on the assessment of the extent of energetic materials contamination on Canadian DND training ranges. This work is carried out with the objective of creating sustainable training conditions for the Canadian Forces. As part of this effort, research is being undertaken to study, in laboratory conditions, the leaching of explosives from cracked or opened munitio...

If you have an Andrew account, there’s a one in three chance you did. ‘It’ is an e-mail with the subject, “Andrew account password insecure!” that claims your password has been cracked. The message goes on to say that in addition to the risks they pose to personal account security, slipshod passwords are a potent...

Elastic liners are used for in situ repair and retrofitting of pipes as a cost effective alternative to the replacement of damaged parts and sections. In this paper, we studied the role of an elastic liner on the buckling behavior of a cracked cylindrical shell using finite element method. A special meshing scheme that could mimic the stress singularity at the crack tip was employed to model th...

A study of the mechanisms of cracking-induced mistuning in bladed disks is presented in this paper. An analytical model for a bladed disk was formulated using lumped-mass-beams, and a cracked blade was represented by a beam with a through-crack at the root. Local stiffness reduction due to cracking was incorporated using a flexibility matrix method. The dynamic characteristics of the bladed dis...

The diagnosis of cracked tooth is difficult in the early stage because the symptoms are not consistent, and often a crack line is not visible. Early detection and proper treatment of cracked tooth are important because all cracks have the potential to become a split tooth. 1. Be reminded that cracked tooth occurs usually on mandibular and maxillary first molars in patients in their 40s and 50s....
