Relations between El Nino/Southern Oscillation anomalies and wildland fire activity in the United States     

Albert J. Simard  Donald A. Haines  William A. Main 《Agricultural and Forest Meteorology》1985,36(2):93-104

The 1982–1983 El Nino resulted in climatic anomalies on a global scale, including record high wildland fire activity in Indonesia and record low activity in the United States. This paper describes the El Nino/Southern Oscillation phenomena and possible teleconnections to United States weather. Because precursors of an El Nino may be evident several months before the onset of an event, the phenomena has potential for long-range fire activity predictions.Using 53 years of data, we tested the hypothesis that El Nino events affect annual fire occurrence and area burned in the United States. We found a statistically significant relation between El Nino events and decreased fire activity in the South. Results for the North-Central and Eastern states are weak or inconsistent. There is no evidence for any relation with the Pacific Coast or Rocky Mountain states. Despite the coarse, exploratory nature of this study, the results are sufficiently encouraging to warrant more detailed examination.  相似文献   

Chemical form of selenium in naturally selenium-rich lentils (Lens culinaris L.) from Saskatchewan     

Thavarajah D  Vandenberg A  George GN  Pickering IJ 《Journal of agricultural and food chemistry》2007,55(18):7337-7341

Lentils (Lens culinaris L.) are a source of many essential dietary components and trace elements for human health. In this study we show that lentils grown in the Canadian prairies are additionally enriched in selenium, an essential micronutrient needed for general well-being, including a healthy immune system and protection against cancer. Selenium K near-edge X-ray absorption spectroscopy (XAS) has been used to examine the selenium biochemistry of two lentil cultivars grown in various locations in Saskatchewan, Canada. We observe significant variations in total selenium concentration with geographic location and cultivar; however, almost all the selenium (86-95%) in these field-grown lentils is present as organic selenium modeled as selenomethionine with a small component (5-14%) as selenate. As the toxicities of certain forms of arsenic and selenium are antagonistic, selenium-rich lentils may have a pivotal role to play in alleviating the chronic arsenic poisoning in Bangladesh.  相似文献   

Trichinella pseudospiralis in pig from Croatia     

Relja Beck  Ana Beck  Snježana Lučinger  Tihomir Florijančić  Ivica Bošković  Albert Marinculić 《Veterinary parasitology》2009,159(3-4):304-307

Trichinella spiralis and Trichinella britovi are species that are frequently found in domestic pigs and various sylvatic animals in Croatia. During routine trichinoscopy, non-encapsulated larvae were detected in the muscle tissue of a domestic pig. Artificial digestion revealed a larvae burden of 602 muscle larvae per gram of tissue. Tissue section analysis confirmed the presence of non-encapsulated larvae. Multiplex PCR identified the larvae as T. pseudospiralis. This observation is consistent with the reports of a local veterinary inspector who described the presence of non-encapsulated Trichinella in four individual cases over the last 2 years. This is the first report of T. pseudospiralis in Croatia and one of very few cases of T. pseudospiralis infection described in domestic pigs. The detection of non-encapsulated larvae stresses the need for implementation of artificial digestion instead of trichinoscopy for the detection and identification of Trichinella infections.  相似文献   

A 160,000-year record of dune development and atmospheric circulation in Southern Arabia     

Preusser F  Radies D  Matter A 《Science (New York, N.Y.)》2002,296(5575):2018-2020

Aeolian deposits in the Wahiba Sands, Sultanate of Oman, reveal patterns of atmospheric circulation over the past 160,000 years. Luminescence dating indicates a correlation of dune activity with periods of low global sea level and decreased monsoon intensity. Evidence from dune orientation and sedimentary structures shows exclusively northbound transport of sand during times of high- latitude glaciation. These results are in contrast to the current paleocirculation model that assumes an increase of northwesterly winds because of a southward shift of the Intertropical Convergence Zone. Our results indicate that the circulation pattern during glacial times was comparable to that of the present.  相似文献   

Mannose receptor-mediated regulation of serum glycoprotein homeostasis     

Lee SJ  Evers S  Roeder D  Parlow AF  Risteli J  Risteli L  Lee YC  Feizi T  Langen H  Nussenzweig MC 《Science (New York, N.Y.)》2002,295(5561):1898-1901

Carbohydrates are thought to function as tags that mark circulatory glycoproteins for rapid clearance. To examine the role of the mannose receptor (MR) in glycoprotein clearance, we generated mice genetically deficient in MR. MR-/- mice were defective in clearing proteins bearing accessible mannose and N-acetylglucosamine residues and had elevated levels of eight different lysosomal hydrolases. Proteomic analysis of MR-/- and control mouse sera showed that an additional 4 out of 52 proteins identified were elevated in MR-/- serum. Each of these is up-regulated during inflammation and wound healing. Thus, MR appears to operate as an essential regulator of serum glycoprotein homeostasis.  相似文献

Nitratverlagerung aus der gülle unter winterzwischenfrucht. Lysimeter‐experimente mit 15N auf einem lehmigen sandboden und einem löss‐lehmboden>     

Hans Lippold  Erhard Albert 《Archives of Agronomy and Soil Science》2013,59(3):183-187

In Lysimeterversuchen in Leipzig 1992–94 wurde die Verlagerung (tiefer 1m) von im Herbst und im Frühjahr ausgebrachter ¹⁵N‐markierter Rindergülle (70 kgN/ha) geprüft. Die starken Niederschläge von März bis Mai 1994 (303 mm) führten zu 25 kg N‐Auswaschung auf dem leichten Boden (1S) und zu 15 kg N‐Auswaschung auf dem schwereren Boden (LLö) aus der Gülle vom Herbst. Anbau von Winterzwischenfrucht verminderte die Auswaschung auf etwa die Hälfte. Im Frühjahr ausgebrachte Gülle unterlag auch im Extremjahr 1994 nur zu 3 kgN der Auswaschung.  相似文献
