Introduction: The Chicxulub Scientific Drilling Project (www.icdp-online.de) recovered a continuous core from a depth of 404 m (in Tertiary cover) to 1511 m (in a megablock of Cretaceous target sediments), penetrating ~100 m of melt-bearing impactites between 794 and 895 m. The Yaxcopoil-1 (YAX-1) borehole is ~60-65 km from the center of the Chicxulub structure, which is ~15 km beyond the limit...

Number and kinds of cattle trails may have a dram&c impact on relative l mouut of bare soil and subsequently on amount and rate of soil erosion. The objective of this study was to quantify the effect of a celldesigned, rotational grazing treatment (RG) on dens&y and kinds of cattle trails. Density of cattle trafls in the RG treatment w8s compared to those hr heavy continuous (HC), moderate cont...

Iceberg C-18a (35 7 0.184 km) was studied repeatedly by five circumnavigational surveys in March-April 2009. During the period of the surveys, C-18a travelled 109 nautical miles in 23 days covering an area of 8.1 10 km. This iceberg was formed from iceberg C-18 (76 7 km) that originated from the Ross Ice Shelf in May, 2002. Ship-based measurements show that this iceberg produced fresh meltwater...

Introduction: Transportation causes stress in chicks that may make numerous physiological changes with a negative impact on their production and health. This study was conducted to examine the effects of injection of diazepam, melatonin, methocarbamol and glucose on Serum biochemical parameters include: glucose, total protein, albumin, uric acid, cholesterol, triglycerides, Ca, P, Zn, Fe, Na an...
