maximizing economic earnings is the most common goal in cut-off grade optimization of open-pit mining operations. when this is the case, the price of the product has a critical effect on optimum value of cut-off grade. this paper investigates the relationship between optimum cut-off grade and price to maximize total cash flow and net percent value (npv) of operation. in order to visualize this ...
Tumoral neoangiogenesis characterizes high grade gliomas. Relative Cerebral Blood Volume (rCBV), calculated with Dynamic Susceptibility Contrast (DSC) Perfusion-Weighted Imaging (PWI), allows for the estimation of vascular density over the tumor bed. The aim of the study was to characterize putative tumoral neoangiogenesis via the study of maximal rCBV with a Region of Interest (ROI) approach i...
Proliferating cell nuclear antigen (PCNA) grade (a semi-quantitative assessment of the entire tumor profile) and estimation whether PCNA grade is low (0-50% positive cells) or high (51-100% positive cells) has been demonstrated to be of prognostic significance in gastric carcinoma. Sixteen vertical growth phase melanomas with 8 or more years of clinical follow-up were reacted with antibody to P...
We present a computational notion of Lexical Tightness that measures global cohesion of content words in a text. Lexical tightness represents the degree to which a text tends to use words that are highly inter-associated in the language. We demonstrate the utility of this measure for estimating text complexity as measured by US school grade level designations of texts. Lexical tightness strongl...
the effects of aflatoxin (af) (0.0 and 0.5m g kg-1) and high grade sodium bentonite (hgsb) (5, 7.5 and 10 g kg-1) were tested in an in vivo study including 8 dietary treatments with three replicates of 14 birds per diet per replicate, using a total of 336 broiler chicks up to five weeks. results showed that chicks receiving af contaminated feed had significantly (p≤ 0.05) suppressed body weight...
background & aim: the most common primary brain tumors of the central nervous system are gliomas. among a number of different biomolecular events, a strong relation between oxidative stress pathways and the development of this cancer has been proved. oxidative stress (os) is the consequence of an imbalance between pro-oxidants and antioxidants towards pro-oxidants. the pro-oxidants cause lipid ...
