The use of proteins and peptides as human therapeutics has been increased in recent years. Lipase is a relatively homogeneous proteinaceous enzyme indicated in maldigestion. The purpose of the present study was to evaluate the effect of humidity along with compactional pressure on the enzymatic activity of wheat germ lipase. Samples of lipase powder were kept at different relative humidity (RH)...

In locally compact spaces, (Borel-)measurable sets can be approximated by compact sets. Ulam extended this result to complete separable metric spaces. We give a constructive proof of Ulam’s theorem. It is first proved intuitionistically and then, using a logical ‘trick’ due to Ishihara, a proof acceptable in Bishop-style mathematics is obtained. We feel this proof provides some insight into Ish...

In this study, fly ash (FA) compacts were prepared by accelerated carbonation as a potential sustainable building material application with the locally available ashes (oil shale (OSA), wood (WA) and land filled oil (LFA)) of Estonia. The behaviour FAs performance 100% FA based evaluated on obtained values CO2 uptake compressive strength. influence different variables (compaction pressure, curi...

The shape memory effect and superelastic properties of NiTi (or Nitinol, a nickel-titanium alloy) have already attracted much attention for various biomedical applications (such as vascular stents, orthodontic wires, orthopedic implants, etc). However, for vascular stents, conventional approaches have required coating NiTi with anti-thrombogenic or antiinflammatory drug-eluting polymers which a...

The mechanical strength of pharmaceutical compacts is an important in-process control parameter to ensure that tablets have sufficient strength to withstand handling during production, transport and use. The introduction of the “Brazilian test” into the pharmaceutical sciences by Fell and Newton has enabled a fundamental understanding of the stresses involved in the breaking of compacts and pro...

Effective rural governance is the foundation for achieving revitalization and promoting modernization of China’s system capacity in new era. The elucidation influencing factors driving pathways underlying effective has significant importance facilitating advancement revitalization. Drawing upon Actor-Network Theory (ANT), this study introduces an analytical framework “human actor dimension—non-...

The effect of PTFE, continuous boron, and tungsten fibers on the combustion behavior strength reactive Ni–Al compacts was examined in this study. introduction into according to developed scheme found increase flexural from 12 120 MPa. Heat treatment (HT), leading chemical interaction starting components, increases at temperatures not exceeding 550 °C. combination reinforcement HT significantly ...

The compressibility and compactibility studies of binary mixtures containing chitosan (CS) and xanthan gum (XG) were highlighted in this article. The compressibility of the examined powders was studied according to Heckel and Gurnham equations. Results indicated that CS exhibits more ductile character than XG. Moreover, in this study percolation theory has been applied to the tensile strength o...

Explosive shock compaction was used to consolidate powders obtained from melt-spun Pr2Fe14B/ –Fe nanocomposite ribbons, to produce fully dense cylindrical compacts of 17–41-mm diameter and 120-mm length. Characterization of the compacts revealed refinement of the nanocomposite structure, with approximately 15 nm uniformly sized grains. The compact produced at a shock pressure of approximately 1...
