The results of a biodiversity monitoring program conducted in the Ogawa Forest Reserve and its vicinity, situated in a temperate region of Japan, identified three different patterns for species richness. Monitoring Insects to Maintain Biodiversity in Ogawa Forest Reserve
Status Date: ApProject Overview Project Name: Ka Xu Solar One Country: South Africa Location Power | NREL Ka Xu Solar One This page provides information on Ka Xu Solar One, a concentrating. lepraemurium from murine leproma was cultivated on the Ogawa yolk medium by adding phenylacetic acid, growth inhibition was brought by the compound.Ĭoncentrating Solar Power Projects - Ka Xu Solar One | Concentrating Solar Thus, phenylacetic acid was identified as the key odor component produced by M. A mixture of authentic phenylacetic acid, its methyl and ethyl esters, smelled similar to the odor of cultivated medium of M. Phenylethanol and phenylacetic acid were identified as major odor components. The condensate was analyzed by Gas-Chromatography-Mass-Spectrum (GC-MS). Then the odor components were eluted from the charcoal with ethanol and the eluate was condensed under nitrogen gas flow at 40 degrees C. After washing with distilled water for three times, the charcoal was dried. The odor components in the extract was adsorbed on refined charcoal. lepraemurium had been cultivated for two months. The odor components were extracted for overnight with sterilized and distilled water from the Ogawa yolk medium on which M. Therefore, identification of the components responsible for the specific odor produced by M. This odor was not observed in other easily cultivable acid-fast bacilli. When Mycobacterium lepraemurium is grown on the 1% Ogawa yolk medium, it produces a specific odor. The Ogawa passive sampler ( Ogawa USA, Pompano Beach, Florida) is a useful tool for monitoring atmospheric ammonia (NH 3(g)) concentrations and assessing the effects of agricultural waste management practices on NH 3(g) emissions. VALIDATION OF OGAWA PASSIVE SAMPLERS FOR THE DETERMINATION OF GASEOUS AMMONIA CONCENTRATIONS IN AGRICULTURAL SETTINGS.
The use of Palmes meshes in Ogawa samplers reduced the cost of sampler preparation and removed uncertainty associated with the unknown The uptake rate of Ogawa samplers was not associated with wind-speed resulting in a high correlation between estimated concentrations and observed analyser concentrations. across multiple sites with different unknown exposures to local winds, and personal exposure monitoring, are likely to benefit from protection of these sampling devices from the effects of wind, for example by use of a mesh or membrane across the open end. Monitoring situations where it is difficult to reliably estimate wind-speed variations, e.g. Computation of adjusted uptake rates using average wind-speed observed during each sampling period increased the variation in analyser concentrations explained by Palmes and Ogawa estimates to 90% and 92% respectively, suggesting that measurements can be corrected for shortening of diffusion path lengths due to wind-speed to improve the accuracy of estimates of short-term NO2 exposure. Uptake rates for Palmes and Ogawa samplers were positively and linearly associated with wind-speed (P < 0.01 and P < 0.05 respectively). The Ogawa, Ogawa and Palmes samplers explained 93%, 87% and 58% of temporal variation in analyser concentrations respectively. Duplicate relative standard deviation was <7% for all passive samplers. We deployed these passive samplers close to the inlet of a chemiluminescence NO2 analyser at an urban background site in Glasgow, UK over 32 discrete measurement periods. We assessed the precision and accuracy of nitrogen dioxide (NO2) concentrations over 2-day, 3-day and 7-day exposure periods measured with the following types of passive diffusion samplers: standard (open) Palmes tubes standard Ogawa samplers with commercially-prepared Ogawa absorbent pads ( Ogawa) and modified Ogawa samplers with absorbent-impregnated stainless steel meshes normally used in Palmes tubes ( Ogawa).
