Four metasedimentary zircon populations from different tectonometamorphic units of the Central and the Northern Schwarzwald (Variscan belt, SWGermany) were investigated using SEM, cathodoluminescence and SHRIMP dating. Despite partially strong modifications of primary internal morphologies during Variscan metamorphism at amphibolite (750 C, 0.4– 0.6 GPa) and granulite-facies conditions (950–1,0...
Shrimp farming in Iran is one of the fast growing segments of the economy. In 1994, around 1% of Iranian shrimp production was farmed and by 2004 the share of shrimp farming increased to 60%. In spite of the fact that shrimp culture had relatively rapid growth in last decade, due to increase in production cost and decrease in international price, the profit of shrimp production has decreased in...
Although the quest for Earth's oldest rock is of great importance, identifying the youngest exposed pluton on Earth is also of interest. A pluton is a body of intrusive igneous rock that crystallized from slowly cooling magma at depths of several kilometers beneath the surface of the Earth. Therefore, the youngest exposed pluton represents the most recent tectonic uplift and highest exhumation....
BACKGROUND Shrimp is a frequent cause of food allergy. Tropomyosin is the major allergen in shrimp, and it shares homology to tropomyosins from other crustaceans, dust mites, cockroach, and parasites. OBJECTIVE The aim of this study was to determine the value of detection of IgE to shrimp tropomyosin in the diagnosis of shrimp allergy. METHODS We have studied 35 patients with asthma, rhinit...
The survey on tilapia-shrimp polyculture was conducted in Thailand and Vietnam from March through June 2002. The survey conducted in Thailand was to assess the current status of farmers’ practice of tilapia-shrimp polyculture, while the survey conducted in Vietnam was to find out why Vietnamese shrimp farmers do not grow tilapia in shrimp ponds. In twelve provinces of Thailand, 61 farmers who c...
aflatoxins (afs) are one of the most important mycotoxins due to their common occurrence in feedstuffs and feeds that pose a serious threat to humans and animals. although many outbreaks of acute and chronic diseases have been attributed to consumption of aflatoxin-contaminated foods, the most significant effect of aflatoxin is hepatotoxicity in farm animals, especially aflatoxicosis in shrimps...
Waters and Stafford (Reports, 23 February 2007, p. 1122) provided useful information about the age of some Clovis sites but have not definitively established the temporal span of this cultural complex in the Americas. Only a continuing program of radiometric dating and careful stratigraphic correlations can address the lingering ambiguity about the emergence and spread of Clovis culture.
