plants. The geographical and climatological condition of Querétaro city, and having a large industrial corridor are risk factors for development allergic problems. In Mexico there are no prevalence studies on food allergy and therefore the most common food allergens. The objectives of the study are to identify common allergen sensitization and to determine if there is crossreactivity between cy...

Failure of hollow trees in urban areas is a worldwide concern, and it can be caused by different mechanisms, i.e. bending stresses or flattening-related failures. Here we derive a new analytical expression for predicting the bending moment for tangential cracking, and compare the breaking moment of various failure modes, including Brazier buckling, tangential cracking, shear failure and convent...

Previous surveys of wild ungulates indicate that the liver fluke, Dicrocoelium dendriticum, was rare in the Cypress Hills area of southeastern Alberta. However, 41 of 59 wapiti (Cervus elaphus) sampled during the 2003 and 2004 hunting seasons from this region were infected, with 7 hosts containing >1,000 worms. Prevalence and mean intensity were similarly high in sympatric beef cattle and mule ...

Variation in individual kernel moisture content (MC) distributions in rice panicles were measured for rice cultivars Bengal, Cypress, and Drew. Rice panicles were harvested at different stages of maturity from foundation seed fields at two locations with widely varying soils in Arkansas during the autumns of 1998, 1999, and 2000. The objective was to quantify variability of individual rice kern...

The mechanism of hydrothermal liquefaction of cypress was investigated by examining the effects of temperature and retention time on the characteristics of the solid residues remaining after liquefaction. The solid residues were divided into acid-soluble and acid-insoluble residues. Results showed the polymerization reactions also mainly occurred at low temperatures. The reactive fragments tran...

The silicified wood samples identified in Western Anatolia are located the Late Miocene-Pliocene aged Çokköy Formation Tavşanlı (Kütahya) and its surroundings, Osmancalı (Manisa) vicinity Early (?)-Middle Miocene Foça Tuff Banaz (Uşak) around Middle-Late Yeniköy within terrestrial sediments. formation of woods petrified by silicification mechanism is associated with sedimentation clastic sedime...
