Purple America
A merica, we are told, is a nation divided. Maps of the electoral votes cast by the states in recent U.S. presidential elections reveal a striking pattern. The base of the Democratic Party is firmly rooted in the northeast and upper Midwest—a region stretching from Maine to Minnesota—plus the Pacific West, anchored by California. The Republicans are said to own an L-shaped region covering the S...
متن کاملDetection of Purple Sulfur Bacteria in Purple and Non-purple Dairy Wastewaters.
The presence of purple bacteria in manure storage lagoons is often associated with reduced odors. In this study, our objectives were to determine the occurrence of purple sulfur bacteria (PSB) in seven dairy wastewater lagoons and to identify possible linkages between wastewater properties and purple blooms. Community DNA was extracted from composited wastewater samples, and a conservative 16S ...
متن کاملTropical Rain Classification and Estimation of Rain from Z-r (reflectivity-rain Rate) Relationships
A Z-R relation is derived using a data set which consists of nine rain events selected from Singapore’s drop size distribution. Rain events are separated into convective and stratiform types of rain using two methods: the Gamache-Houze method, a simple threshold technique, and the Atlas-Ulbrich method. In the Atlas-Ulbrich method, the variability of the rain integral parameters R, Z, Nw, D0 and...
متن کاملAcid Rain
Pure water has a pH of 7.0 (neutral); however, natural, unpolluted rainwater actually has a pH of about 5.6 (acidic).[Recall from Experiment 1 that pH is a measure of the hydrogen ion (H+) concentration.] The acidity of rainwater comes from the natural presence of three substances (CO2, NO, and SO2) found in the troposphere (the lowest layer of the atmosphere). As is seen in Table I, carbon dio...
متن کاملRain structure transfer using an exemplar rain image for synthetic rain image generation
This letter proposes a simple method of transferring rain structures of a given exemplar image (rain image) into a target image (non‐rain image). Given the exemplar rain image and its corresponding masked rain image, rain patches including real‐life rain structures are extracted randomly, and then residual rain patches are obtained by subtracting those rain patches from their mean patches. Next...
