long-term ingestion of large amounts of fluoride can lead to potentially severe skeletal problems and neurological consequences. the study was conducted to assess and compare intelligence quotient of children living in high and low fluoride areas in kutch, gujarat, india.a cross-sectional descriptive survey was conducted among 100 school children aged 8 to 10 years, living in kutch district, gu...

this study was performed during the abatement of two asbestos-containing materials (acm):baumlite board (cement flat board) and ceiling textile. the concentrations of total dust for personal sampling were 0.28 and 1.70 mg/m3 during baumlite board and ceiling textile abatements, respectively, when calculated with 8-hr time-weighted average (twa). the geometric mean (gm) asbestos concentrations w...

effects were studied of 200 ppm silver and copper nano-suspensions, with size range from 20 to 80 nm, on the hardness of particleboards produced at an industrial scale at the iran-choob factory, iran. metal nano-suspensions were added to the mat at two levels of 100 and 150 milli-liters/kg dry weight wood particles, and the results were compared with those of the control panels. results showed ...

It is generally accepted that the most basic obstacle to continued advances in the speed of computing systems is metal connections. The bottleneck of current metal-based interconnection networks is typically the very limited bandwidth. Optics, due to its inherent parallelism, high bandwidth, freedom from planar constraints, and non-interfering communication, has been recognized as a possible so...

PROJECT GOALS SRI and U.C.Berkeley are developing hardware for a real-time implementation of spoken language systems (SLS). Our goal is to develop fast speech recognition algorithms and supporting hardware capable of recognizing continuous speech from a bigram or trigram based 10,000 word vocabulary or a 1,000 to 5,000 word SLS system. RECENT RESULTS The special-purpose system achieves its high...

background the critical role that the board plays in governance of universities clarifies the necessity of evaluating its performance. this study was aimed to evaluate the performance of the boards of medical universities and provide solutions to enhance its performance.   methods the first phase of present study was a qualitative research in which data were collected through face-to-face semi-...

Residue of the branch wood camphor tree (Cinnamomum camphora) was used to manufacture binder-free biodegradable biomass fiberboard (bio-board) by wet method. To investigate mechanical properties bio-board, bending rupture stress and tensile tests were measured effect heating temperature applied pressure on performance bio-board evaluated. Scanning electron microscopy (SEM) Fourier transform inf...

Package on Packages (PoP) find use in applications that require high performance with increased memory density. One of the greatest benefits of PoP technology is the elimination of the expensive and challenging task of routing high-speed memory lines from under the processor chip out to memory chip in separate packages. Instead, the memory sits on top of the processor and the connections are au...
