the oudna field part of the offshore northeastern tunisia, straddles between two structural domains, the tunisian atlas to the north and the pelagian sea to the south. the study of this field has confirmed adequate petroleum system in fahdene formations (albian-cenomanian) and birsa (serravallian) resulting from the combination of several sedimentary, tectonic and thermal factors. to do this, w...

Sarvak Formation as the oil reservoir with the most hydrocarbon potential in Yaran oil field is of special importance. The present research was conducted to study the reservoir parameters of this Formation. For this purpose, petro-physical crude data was first prepared and using the Geolog6.7 software, a petro physical plot was drawn. Afterward, petro-physical properties of reservoir were done ...

Hydraulic analogs of bioelectrical potentials are proposed as teaching tools in helping students with no formal background in physics and mathematics. Membrane capacitance is simulated by a water reservoir, V, whose variable level is the membrane potential. Resting membrane potential is simulated by a large capacitance reservoir of fixed level, connected to reservoir V through a tube having the...

monthly and annual water and phosphorus mass budgets were set up over the year 2010 for thelake rio verde, brazil. limited data for the water budget was compensated using an interpolation methodwith data water budget data of a nearby reservoir. thus, errors of ca. 1.5% were estimated for the waterbudgets. dominant p mass input terms were inflows from the rivers and direct run off into the reser...

The well Sarai Sidhu-01 is located on Punjab Platform, Central Indus Basin, Pakistan. Punjab Platform is the eastern part of Central Indus Basin, and tectonically it is the stable portion of Indus Basin, which was least affected during Tertiary Himalayan orogeny. This study attempts to decipher reservoir potential for hydrocarbon exploration. It aims to delineate a subsurface hydrocarbon bearin...

Summary The Arctic is currently warming at unprecedented rates because of global climate change, resulting in thawing large tracts permafrost soil. A great challenge understanding the implications thaw on human health and environment. Permafrost a reservoir mostly uncharacterized microorganisms viruses, many which could be viable. Given our limited knowledge permafrost-resident microbe...

Leeches, fed on swine infected with hog cholera, contained virus for as long as 87 days after their infective blood meals. In three instances, infected leeches apparently transmitted hog cholera virus to susceptible swine in the process of normal feeding. Myxoma virus persisted in leeches for as long as 154 days after the ingestion of a blood meal from rabbits with myxomatosis. Leeches fed cons...

Morphometrics and physico-chemical parameters of Oyun reservoir, Offa, Nigeria (a small shallow tropical African Reservoir) were used to estimate the potential fish yield of the reservoir according to the morpho-edaphic index (MEI). Physico-chemical characteristics of the water body were sampled monthly from three stations between January 2002 and December 2003 with standard methods. Estimates ...
