The surficial deposits surrounding the Mount Meager volcanic complex include numerous avalanche deposits. These deposits share many attributes: (a) they are nearly monolithologic and comprise mainly intermediate volcanic rock clasts, (b) they lack internal structure, and (c) they are very poorly sorted. Despite these similarities, the avalanche deposits represent two distinct processes. Mass wa...

BACKGROUND The role of calcium oxalate crystals and deposits in UTI pathogenesis has not been established. The objectives of this study were to identify bacteria present in pediatric urolithiasis and, using in vitro and in vivo models, to determine the relevance of calcium oxalate deposits during experimental pyelonephritis. METHODS Pediatric kidney stones and urine were collected and both cu...

BACKGROUND Soft tissue deposits of squamous cell carcinoma in the necks of patients with squamous cell carcinoma of the upper aerodigestive tract may represent either total effacement of a lymph node by carcinoma or extralymphatic deposits of carcinoma. There are few reports of their clinical or prognostic significance. METHODS Data from 215 neck dissections from 155 patients with squamous ce...

Brachiopod faunas from the Aptian- Cenomanian Vezk section in southwesternIran comprise ten species in six genera, namely Sellithyris cenomanensis, Sellithyris tornacensis, Sellithyris phaseolina, Phaseolina phaseolina, Tropeothyris sp., Concinnithyris subundata, Kingena arenosa, Cyclothyris difformis, Cyclothyris sp. and Cyclothyris compressa. All species are recorded for the first time from t...

Moon Mineralogy Mapper spectroscopic observations are used to assess the mineralogy of five sites that have recently been proposed to include lunar dark mantle deposits (DMDs). Volcanic glasses have, for the first time, clearly been identified at the location of three of the proposed pyroclastic deposits. This is the first time that volcanic glasses have been identified at such a small scale on...

calculating total cast of bank resources procurement methods which include current -free loan deposit, saving interest-free loan deposit, regular and net short-term investment deposit, long-term investment deposit and surety bond cash deposit and presenting their optimal integration require precise scientific studies. hence, this study is an attempt to know which methods are the best optimal in...

seismic ground motion is profoundly affected by geometrical and mechanical properties of soil deposits overlaying bedrock. local seismic ground response of saturated soil deposits was studied in literature by applying the effects of soil stress state and index properties on the strain-dependent normalized shear modulus reduction, g/g0, and damping ratio, d, curves in an equivalent linear analys...

Three patients with the central type of neurofibromatosis, who on CT showed multiple subependymal calcified deposits, are presented. The literature on intracranial non-tumourous calcifications in neurofibromatosis is briefly reviewed. On the basis of our findings and the literature, it is proposed that such intracranial calcified deposits may be part of the neurofibromatosis syndrome and are ca...

damavand is a large dormant stratovolcano in the alborz mountains of northern iran located in one of the most populous provinces, which could be adversely affected by tephra fall from damavand. the youngest known eruption is a lava flow on the western flanks with an age of 7.3 ka. the volcanic products are predominantly porphyritic trachyandesite. three major young pumice deposits, named here a...
