to evaluate the relationship between total organic carbon (toc) and rock-eval s2 (petroleum potential) of petroleum source rocks, atotal of 180 outcrop samples from the black organic matter–rich facies of mesozoic strata from a locality of southwest of iran wereinvestigated using rock-eval vi pyrolysis and leco carbon analyzer. the linear regression is applied to determine the correlationbetwee...

We analyzed relations between the content of total organic carbon (TOC) and the content of soil organic matter (SOM) in 47 soil profiles dug out in dry coniferous forests, fresh coniferous forests, and mixed deciduous-coniferous forests. Soils in the analyzed sites are derived from sands. In each soil horizon, bulk density (BD), pH, soil texture, and TOC and SOM were determined. Correlation bet...

We conducted experiments to elucidate the mechanism by which alpha-tocopherol (alpha-toc) concentration in the liver remarkably increases in rats treated with polychlorinated biphenyls (PCB) when excess amounts of DL-alpha-tocopheryl-acetate (alpha-toc-ac) were given. First, diets containing 5 and 50 mg of alpha-toc-ac per 100 g were respectively added with 0.05% of PCB and given to rats for 10...

Since the development bloom in unconventional reservoirs in North America, total organic carbon (TOC) has become a more essential parameter, as the indicator of the efficiency of these reservoirs. In this paper, by using conventional well logs and NMR log data, the TOC content of an unconventional reservoir in West Africa is estimated. Passy’s, Issler’s, and Schmoker’s methods were used as indi...

this paper is based on the recent development to literature on organizational culture and its role in management thory and practices. based on the review of literature, both management theories and organizational culture the author finds significant interrelation and interaction between the management theory and the systems of shared values, norms and behaviors held by the people in a given org...

We examined the use of dC, TOC and C/N geochemistry of sedimentary organic matter to reconstruct former sea levels and paleoenvironments in the absence of suitable microfossil data. The modern distribution of dC, TOC and C/N of 33 vegetation and 74 surface sediment samples collected from four coastal wetlands in the Thames Estuary and Norfolk, UK are described. The dC, TOC and C/N geochemistry ...

We have previously reported that gamma-tocopherol (gamma-Toc) displays a natriuretic potency in rats fed a NaCl diet and administered 20 mg gamma-Toc. In this study, we investigated whether gamma-Toc has natriuretic potency at a dose lower or higher than 20 mg in rats given a NaCl diet. Male rats were fed a control diet or a NaCl diet and administered either placebo or 10, 20 or 40 mg of gamma-...

BACKGROUND For Chlamydia trachomatis (CT), a test of cure (TOC) within 3-5 weeks is not recommended. International guidelines differ in advising a Neisseria gonorrhoeae (NG) TOC. Retesting CT and NG positives within 3-12 months is recommended in international guidelines. We assessed TOC and retesting practices including extragenital testing in general practitioner (GP) practices located in diff...
