Suspended particulate and bioaerosol levels were measured at three sites downwind of an agricultural non-point source during the wheat harvesting season. Suspended particulates were detected at mean values ranging from 10000 to 2420 micrograms m-3 at distances of from 20 to 60 m downwind of the source, respectively. Airborne viable bacterial counts were recorded at mean values ranging between 1...

MISTRETTA, CHARLOTTE M. Permeability of tongue epithelium and its relation to taste. Am. J. Physiol. 220(5) : 1162-l 167. 197 1 .-The permeability of rat tongue epithelium was investigated to provide information on the accessibility of free lingual nerve endings to chemical stimuli. Permeability of rat belly skin was also studied. Dorsal tongue epithelium was removed after subepithelial injecti...

The etiology of depression has not yet been defined with certainty. The successful use of botulinum toxin recently to treat depression has brought to attention the theories which connect emotions with facial muscles. According to facial feedback hypothesis, facial muscles not only express emotions but also cause and/or alter them. It has been long suggested that a disturbance in the process of ...

TO THE EDITOR: I read the report by Kang et al regarding “prevalence and predictive factors of fecal incontinence.” In this study, most of fecal incontinence was mild form and related with water or loose stool consistency. The result was consistent with report by Bharucha et al. I believe that bowel disturbance (ie, diarrhea and irritable bowel syndrome) is the most common cause of fecal incont...

Melioidosis is being increasingly recognized as an important cause of severe, acute community-acquired pneumonia in various tropical regions. The chronic form of melioidosis can also mimic tuberculosis. Studies have established that, while uncommon in the Port Moresby region, melioidosis is an important cause of pneumonia and sepsis in the Balimo region of Western Province. Phylogenetic analyse...

TO THE EDITOR: I would like to thank Dr. Lee for his thoughtful comments on the impact of constipation on fecal incontinence. The coexistence of fecal incontinence and constipation has been well characterized in children and the geriatric population. Fecal incontinence in children is secondary to ‘overflow’ which results from the presence of constipation. Also fecal incontinence occurs in a var...

Silicosis is an incurable non-infectious occupational disease. It is one of the pneumoconioses, a generic group of long diseases associated with dusty occupations. Silicosis is caused by continuous inhalation of microscopic particles of free silica (quartz) dust measuring from one to three microns in diameter (a micron is equivalent to 0,0001 centimetres). If these particles penetrate to the de...

The near-infrared integral field spectrograph SINFONI at the ESO VLT opens a new window for the study of central supermassive black holes. With a near-IR spatial resolution similar to HST optical and the ability to penetrate dust it provides the possibility to explore the low-mass end of the M•-σ relation (σ < 120 km s−1) where so far very few black hole masses were measured with stellar dynami...

For the generation of topographic maps generally the ground elevation rather than the surface elevation is required, which can be realized, if at all, only with large wavelengths that penetrate the vegetation foliage. This paper reports about a project in the Brazilian Amazon region where Aerosensing's P-band airborne interferometric SAR has been used to map a part of the rainforest. The P-band...
