We explore the rotation and activity of very low mass (VLM) objects by means of a photometric variability study. Our targets in the vicinity of ǫOri belong to the Ori OB1b population in the Orion star-forming complex. In this region we selected 143 VLM stars and brown dwarfs (BDs), whose photometry in RIJHK is consistent with membership of the young population. The variability of these objects ...

The present study is focused on sediment core MD02–2521 in the Gulf of Tehuantepec (GT). This area, situated within Oxygen Minimum Zone (OMZ), rich marine resources due to seasonal upwelling caused by Tehuanos winds and a shallower thermocline representing an important economic sector region; however, has been focus little number studies. Benthic foraminifera (BF) are target proxy reconstruct b...

Regardless the crop production, range and livestock management is unlikely to be possible. Considering the range production is essential for efficient and effective range management. This study aims to investigate the relationship between the rate of forage production and the effects of climate variables. For this purpose, forage yield of four range species including Artemisia sieberi, Scar...

Numerous methods are currently used throughout the poultry industry for the administration of vaccines. Each utilizes water for vaccine reconstitution and/or administration, including two of the three commercially available live Mycoplasma gallisepticum (MG) vaccines. Selected water temperatures were used to reconstitute and/or dilute the three commercially available live MG vaccines. Water tem...

During the Pleistocene, long-term trends in global climate were controlled by orbital cycles leading to high amplitude glacial-interglacial variability. The history of Amazonian vegetation during this period is largely unknown since no continuous record from lowland basin extends significantly beyond last glacial stage. Here we present a paleoenvironmental spanning 1800 kyr based on palynologic...
