investigation of projectiles penetration phenomenon has been carried out in non-cohesive soil (sand) targets under dry, saturated and compacted conditions. analytical studies have been performed on the linear and non-linear soil models to obtain penetration depth formulae for ogival nose projectile and the results are verified by experimental studies. in present work, three ogival nose projecti...

BACKGROUND The main aim of this cross-sectional study was to investigate the prevalence and severity of erosive tooth wear and its association with dental caries and socio-demographic factors among middle-aged Finnish adults. METHODS Of the total Northern Finland Birth Cohort 1966 (n = 12,058), a convenience sample (n = 3181 adults) was invited for an oral health examination of which 1962 (61...

Introduction: Oral Lichen Planus (OLP) is one of the most common mucocutaneous lesion, and its etiologic factors have not been elucidated yet. OLP has two different clinical forms including reticular and erosive. Mast cells function in non-specific immunology is an etiologic factor involved in the formation of lichen planus. This study aimed at determining the pattern of mast cells presence in ...

OBJECTIVES To investigate systemic inflammation and autoimmune response to citrullinated peptides in patients with erosive and non erosive 'lone' hand osteoarthritis (HOA) with no hip/knee involvement and their relationship with radiographic structural damage. METHODS Sera were obtained from a total of 99 patients with HOA (52 patients with erosive HOA and 47 patients with non-erosive HOA) an...

It is now well established that material naturally moves around the Solar System, even from planetary surface to planetary surface. Accordingly, the idea that life is distributed throughout space and did not necessarily originate on the Earth but migrated here from elsewhere (Panspermia) is increasingly deemed worthy of consideration. If life arrived at the Earth from space, its relative speed ...

The goal of this project was to further mature microspoiler technology to the extent that it could be incorporated into current and future smart weapons designs. Several program objectives, including mechanical design and fabrication, trade study analysis, and limited flight experiments were defined as a collaborative effort between the Georgia Institute of Technology (Georgia Tech) and the Arm...

background: proliferating cell nuclear antigen (pcna) is a nuclear protein synthesized in the late g1 and s-phase of the cell cycle. detection of this protein represents a useful marker of the proliferation status of lesions. this study has been carried out to evaluate the cell proliferation rate in oral lichen planus (olp) and comparison between plaque and erosive lichen planus, which indicate...
