1. In a search for suitable tissues for the cultivation of yellow fever virus in vitro, mouse embryos were inoculated with this virus in utero. A titration for virus content of the various organs of the embryos indicated that the virus was present in the brain in greatest concentration. 2. Unmodified strains of yellow fever virus were readily adapted to cultivation in vitro in a medium consisti...

Illegal cannabis (Cannabis sativa L.) cultivation is still a social problem worldwide. Fifty inquiries on cannabis that Research Center for Medicinal Plant Resources (Tsukuba Division) received between January 1, 2000 and March 31, 2009 were itemized in to 8 categories; 1: seed identification, 2: plant identification, 3: indoor cultivation, 4: outdoor cultivation, 5: germination and growth char...

Both UNODC and U.S. surveys of opium poppy cultivation indicated a significant increase in cultivation and potential production in 2007, and production and export of synthetic drugs (amphetamine-type stimulants, crystal methamphetamine and Ketamine) from Burma continued unabated. (Note: 2008 UNODC Cultivation Report statistics were not available by our printing deadline.) The significant downwa...

This research aimed at investigating the effect of different levels of nitrogen and planting patterns on dry matter production and growth physiological indices in intercropping maize and sunflower. To do this a split plot experiment carried out based randomized complete block design with three replications in research field of Shushtar Islamic Azad University. The main plot included three level...

This paper examines the impacts of agricultural technology changes on farmers' relationship with nature and their environment. Based a field study in Bena Irrigation Area South Amanuban Sub-District, Timor, East Nusa Tenggara, Indonesia, this analyses how introduction new technologies agriculture by Government Indonesia these last 30 years has changed farmer's pattern cultivation, views about e...

A histochemical study of hydrolytic enzymes such as acid phosphatase and beta-glucuronidase was made on cultured brain tumor cells. Well-differentiated astrocytic cells, oligodendroglioma cells, and medulloblastoma cells showed low activities. Migrating cells and macrophage-like cells showed intense activities. Meningioma cells and schwannoma cells showed relatively intense activities at the ea...

Open cultivation systems to monoculture microorganisms are promising for the commercialization of low-value commodities because they reduce the cultivation cost. However, contamination from biological pollutants frequently impedes the process. Here we propose a cultivation method using hollow hydrogel microfibers encapsulating microorganisms. Due to the pore size, hydrogels allow nutrients and ...

This paper analyzed dynamics of crop diversification in one of the agriculturally prosperous districts of Indian Punjab using Gibbs Martin Index. Spatio-temporal analysis of crop diversification in the district shows decline in crop diversification in most of the blocks (administrative sub divisions). The cropping pattern in most of the blocks of the district has become over specialized in the ...

We succeeded in isolating human rotaviruses from the feces of gastroenteritis patients by using roller cultures of primary cynomolgus monkey kidney cells with trypsin in the maintenance medium but without concentration and trypsin treatment of the inocula at each passage level. These cells were found to be more sensitive than MA-104 cells (derived from fetal rhesus monkey kidney) for the propag...

Since the 19th century, opium has been produced and consumed in the areas of Asia, currently referred to as the Golden Crescent and the Golden Triangle (1). The Golden Crescent lies in South and Southwest Asia, including districts in the Northwest Frontier Province of Pakistan, the adjacent Badakhshan area of Afghanistan and the Baluchistan area of Iran. The area has been the scene of tradition...
