Blood and stripped hemoglobin from Nelore cattle individuals were submitted to oxygen equilibrium experiments in both gasometric and spectrophotometric methods. No difference was detected in oxygen affinity and Bohr effect among Hb A, Hb B and Hb AB in experiments with both blood and stripped hemoglobin, in the presence and absence of the chloride ion. However, n values (Hill plots) were higher...

14 Regulatory, safety, and environmental issues have prompted the development of aqueous 15 enzymatic extraction (AEE) for extracting components from oil-bearing materials. The 16 emulsion resulting from AEE requires de-emulsification to separate the oil; when enzymes 17 are used for this purpose, the method is known as aqueous enzymatic emulsion de18 emulsification (AEED). In general, enzyme a...

Blood transfusion centers are under considerable pressure to produce platelet concentrates with a shelf life limit of 3 to 5 days. Many approaches have been investigated experimentally to produce new hemostatically active platelet products that are capable of long term storage. In this article infusible platelet membrane will be explained as a platelet substitute versus conventional liquid-stor...

purpose : to assess the efficacy and safety of sutureless punch trabeculectomy as substitute for conventional scleral flap trabeculectomy. methods : in a prospective, randomized study, 44 eyes of 42 patients with primary open angle glaucoma (poag) who were candidate of trabeculectomy were included and randomly assigned into two groups sutureless punch trabeculectomy or conventional scleral flap...

bile duct ligation (bdl) is shown to induce cholestasis-related liver function impairments as well as consequent cognitive dysfunctions (i.e. impaired learning and memory formation). this study investigates the effects of cholestasis (14, 21 and 28 days post bile duct ligation) on spatial and non-spatial novelty detection, using a non-associative task. male mice weighing 30-35 g were used. chol...

this study aims to estimate the function of copper consumption using the johansen approach in time series data, between 1991-2011 in iran. the literature review of specialized consumption and demand functions shows factors influencing the consumption of copper including copper price variables, aluminum price as a substitute commodity, oil price as a complementary commodity, and industrializatio...

the study was designed to determine the rate of depression prevalence among the guidance and secondary school students in shahreza town on 1384-85. 960 boy and girl students were selected through stratified random sampling method that was assessed through beck depression inventory (bdi). the data were analyzed through frequency and chi square test.this analysis indicated that %12/9 of students ...

in this paper, we consider a cooperative cognitive radio network in which there is an ofdm primary link and multiple single carrier secondary links.the primary link is required to maintain its secrecy rate above a predefined threshold. if the secrecy rate requirement is not satisfied, the secondary system help primary link to maintain its secrecy rate requirement. in doing so, the secondary trans...

The article highlights the risks of using self-evaluation as a substitute for primary and secondary market research when designing and monitoring marketing programs. Included is a study of 110 management teams that suggests internally dominated marketing analysis may breed illusory evaluations of a company’s own marketing programs versus competitors. If acted upon, such illusions could lead to ...
