Ž . Ž X Supercooled drizzle freezing drizzle was observed at Inuvik, N.W.T., Canada 68822 N, X . 133842 W on December 20, 21 and 27, 1995. Meteorological conditions in which the supercooled Ž . drizzle could form under low temperatures colder than y208C in the mid-winter season of the Canadian Arctic were examined from the sounding data and data measured by a passive Ž . microwave radiometer at...

High pressure-rated channels allow microfluidic assays to be performed on a smaller footprint while keeping the throughput, thanks to the higher enabled flow rates, opening up perspectives for cost-effective integration of CMOS chips to microfluidic circuits. Accordingly, this study introduces an easy, low-cost and efficient method for realizing high pressure microfluidics-to-CMOS integration. ...

Local synthesis and direct integration of carbon nanotubes (CNTs) into microsystems is a promising method for producing CNT-based devices in a single step, low-cost, and wafer-level, CMOS/MEMS-compatible process. In this report, the structure of the locally grown CNTs are studied by transmission imaging in scanning electron microscopy-S(T)EM. The characterization is performed directly on the mi...

We present characterizations of few-layer titanium trisulfide (TiS3) flakes which, due to their reduced in-plane structural symmetry, display strong anisotropy in their electrical and optical properties. Exfoliated few-layer flakes show marked anisotropy of their in-plane mobilities reaching ratios as high as 7.6 at low temperatures. Based on the preferential growth axis of TiS3 nanoribbons, we...

In non-febrile mouse models, high dose acetaminophen administration causes profound hypothermia. However, this potentially hazardous side-effect has not been confirmed in non-febrile humans. Thus, we sought to ascertain whether an acute therapeutic dose (20 mg⋅kg lean body mass) of acetaminophen would reduce non-febrile human core temperature in a sub-neutral environment. Ten apparently healthy...

introduction: multiple myeloma is a neoplasm of monoclonal plasmacells which may cause oral manifestations. we report a 50-year-old man with a mass burned out of a post extraction socket. he had recived an eight month period of chemotherapy and was supposed to be ready for hematopoetic stem cell transplantation. after clinical and histopathological examinations, the mass was diagnosed as a plas...

background: ventilator-associated pneumonia (vap) is the most prevalent and lethal form of nosocomial infections in the icu and oral disinfection is a nursing measure to prevent this condition. aim: this study aimed to evaluate the effect of oronasal versus oral disinfections with chlorhexidine on the clinical criteria for diagnosis of vap. method: this randomized clinical trial was conducted o...

The effects of equivalent doses of atropine and hyoscine following oral and i.m. administration were assessed on salivary secretion, heart rate, arterial pressure, body temperature, pupillary size, near-point of vision and sweat-gland activity. The ratio of oral to i.m. doses of atropine on heart rate and salivary secretion appears to be 2:1 and that of hyoscine on salivary secretion about 5-6:...

lichen planus (lp) is a chronic inflammatory disease of probable immune-based etiology. the pathogenesis of lp is unclear, but apoptotic changes in epidermal (epithelial) cells have been reported. destruction of the basal cell layer is observed and many changes in cell proliferation, cell repair and cell death occur in the injured mucosal epithelium. the aim of this study was to evaluate and co...
