Pressurized water reactor (PWR) cores operate under extreme environmental conditions due to coolant chemistry, operating temperature, and neutron exposure. Extending the life of PWRs requires detailed knowledge of the changes in mechanical and corrosion properties of the structural austenitic stainless steel components adjacent to the fuel (internals) that are inherent to such conditions. This ...

Results The USP Class I Min. Avg. 2-0 Suture Knot-Pull Tensile Strength (Doubled for Loop Test) is defined as 2.88 kgf. The Tensile Strength of Lot # 1-9364 was 4,7761 ± 0,2005 kgf (mean ± std dev) min 4.2282, max 5.2289, and for Lot # 1-9364 was 5,5151 ± 0,2625 kgf (mean ± std dev) min 4,0044, max 5,1356, respectively. There were no statistically signiffcant differences between the both lots (...

This study investigated the true stress (σ)–true strain (ε) relationship up to plastic deformation limit in ferrite–pearlite (FP) steel at various temperatures. We found that a decrease temperature resulted an increase lower yield strength (LYS) and tensile (TS), both uniform total elongations. When was increased from 673 773 K, TS elongations decreased due blue brittleness. In σ–ε of FP temper...

The effects of starch and aging on the mechanical properties of starch/poly(hydroxyester ether) (PHEE) composite materials were characterized. Native or modified cornstarches were extruded with PHEE. Composites were aged for up to 20 months at either 23°C and 50% relative humidity (RH) or over calcium sulfate to keep the composites dry. The tensile strength (TS) of the composites was affected b...

The impact of melt extrusion (HME) and spray drying (SD) on mechanical properties of hypromellose acetate succinate (HPMCAS), copovidone, and their formulated blends was studied and compared with that of reference excipients. Tensile strength (TS), compression pressure (CP), elastic modulus (E), and dynamic hardness (Hd ) were determined along with Hiestand indices using compacts prepared at a ...

objective: among the various impression materials, for alginate tear strength is probably more important than the compressive strength. the tear strength is important when an impression involves a mechanical undercut and/or lacks bulk strength to resist tearing. this study evaluated tear strength of iralgin and compared it with tear strength of alginoplast. methods: in this invitro experimental...

UNLABELLED Chitosan is a biopolymer obtained by N-deacetylation of chitin, produced from shellfish waste, which may be employed to elaborate edible films or coatings to enhance shelf life of food products. This study was conducted to evaluate the effect of different concentrations of nanofiller (cellulose nanofibers, CNF) and plasticizer (glycerol) on tensile properties (tensile strength-TS, el...

In this paper, a compression-to-tensile load converter device is developed to determine the anisotropic tensile strength of brittle material. A cubic sample with an internal pore was used as the test specimen, and a series of finite element analysis and DDM simulations were performed thereafter to analyse the effect of pore dimensions on the stress concentration, as well as to render a suitable...

Objective(s): Quince seed mucilage (QSM) serves as a new source of hydrocolloid which extracted from outer pericarp of Cydonia oblonga seeds upon wetting. It has been traditionally used for the treatment of diseases such as pharyngeal disorder, common cold, colic ulcer, and diarrhea. The aim of the present study was to evaluate the physico-mechanical and antimicrobial properties of quince seed ...

Xylan extracts from southern US hardwood were used for the adsorption of both hardwood and softwood pulp. Pulp beatability and physical strength properties were determined and compared with those of the conventional Kraft pulp and pre-extracted modified Kraft pulp. The results indicated that hemicelluloses adsorption greatly improved pulp beatability. Compared to conventional Kraft pulp, a sign...
