The polyurethane membrane is used as a separator either by filtration or adsorption, and this process significantly affected its strength physical condition. We synthesized membranes using red seaweed with Gracilaria sp hydroxyl source. Box-Behnken Design of the Response Surface Methodology (RSM) Software Expert Version 10.0.3.0 three factors (TRL, TDI, Glycerin). F-value 0.42 suggests that les...

The work presented in this paper provides guidance optimally determining the appropriate fitting region used digital image correlation (DIC) when a crack tip field model to DIC data. In work, technique is applied CJP and uses Levenberg-Marguardt (L-M) iterative method solve for position. This combined with an error analysis of main term Williams series expansion stresses extrapolation Saint-Ven...

Background: Low birth weight is one of the most important health indicators for assessing the status of newborns in every country. It is, therefore, necessary to identify factors associated with this adverse pregnancy outcome. This study was conducted to determine predicting factors associated with low birth weight using path analysis. Methods:</stron...

The synthesis and binding properties of new porphyrin cage compounds consisting of a rigid diphenylglycoluril part, which is connected via flexible bis(ethyleneoxy) spacers to a (metallo)porphyrin "roof", are reported. Binding of viologen guests and pyridine ligands in these porphyrin cages are accompanied by significant conformational reorganizations of the hosts. Despite these structural chan...

We have used the 76-m Lovell, 94-m equivalent WSRT and 100-m Effelsberg radio telescopes to investigate the simultaneous single-pulse properties of the radio emitting magnetar AXP XTE J1810–197 at frequencies of 1.4, 4.8 and 8.35 GHz during May and July 2006. We study the magnetar’s pulse-energy distributions which are found to be very peculiar as they are changing on time-scales of days and ca...

BACKGROUND The eosinophilic asthma phenotype (sputum eosinophils 3%) indicates a good response to corticosteroids and T(H)2 immunomodulators. Exhaled nitric oxide (FeNO) is rapidly measured by portable devices, and although it is not a selective marker of eosinophilic inflammation, several studies have demonstrated a strong correlation with it. We investigated which FeNO value was the best fit ...

Earthworm fibrinolytic enzyme component A (EFEa) from Eisenia fetida is a strong fibrinolytic enzyme that not only directly degrades fibrin, but also activates plasminogen. Proteolytic assays further revealed that it cleaved behind various P1 residue types. The crystal structure of EFEa was determined using the MIR method and refined to 2.3A resolution. The enzyme, showing the overall polypepti...

OBJECTIVES To compare the impact of negotiated vs. mainstreamed follow-up with telephone reinforcement (TR) on maintenance of physical activity (PA) after Fit and Strong! ended. METHODS A multisite comparative effectiveness trial with repeated measures. RESULTS Single group random effects analyses showed significant improvements at 2, 6, 12, and 18 months on PA maintenance, lower-extremity ...

the present study aimed at validating the structure of career decision-making difficulties questionnaire (cddq).five hundred and eleven undergraduate students took part in this research; from these participants, 63 males and 200 females took part in the first study, and 63 males and 185 females completed the survey for the second study.the results of exploratory factor analysis (efa) indicated ...

This talk addresses the questions of quantifying how good global fits are, and of how we would know a theory is wrong; it summarizes our Ref. . The obvious criterion is that of hypothesis testing: χ = N ±√2N for a good fit with N degrees of freedom. One should also apply the same criterion to subsets of data (e.g., from a particular experiment or reaction), for which the normal range is χi = Ni...
