This study presents a design criterion developed for fatigue strengthening of a 120-year-old metallic railway bridge in Switzerland and presents a pre-stressed un-bonded reinforcement (PUR) system developed to apply the strengthening. The PUR system uses carbon fiber reinforced polymer (CFRP) plates; however, unlike conventional pre-stressed CFRP reinforcement methods, preparation of the existi...

Excised shoot tips of sweet potato (Ipomoea babatas L.) were incubated in H2O2 or NaCl aqueous solution for 24h or 48h prior to a 3-day chilling at 2.5°C. Severity of chilling injury was visually observed during a post-chilling 7-day recovery at 21°C, and scored at 0 to 5 (none to most severe injury). In the first experiment, when cv. Purple (PUR) sweet potato shoots were subjected to 3-day chi...

A purR::pGh9:ISS1 mutant of Lactococcus lactis was obtained following transposon mutagenesis of strain MG1363 and selection for purine auxotrophs. After determination of the nucleotide sequence and deduction of the purR reading frame, the PurR product was found to be highly similar to the purR-encoded repressor from Bacillus subtilis. The wild-type purR gene complemented the purine auxotrophy o...

This paper mainly examines the fixation performances of cephalomedullary nail for incidence intertrochanteric (IT) fracture to guide appropriate fixations with respect bone density in terms a biomechanical perspective. It is substantially important which types are applied during operation since it tends induce backout or migration helical blade and screw according weight density. Biomedical pol...

Abstract This study introduces fractionated lignin as an innovative component in the formulation of rigid polyurethane/polyisocyanurate (PUR/PIR) foams. Low‐density PUR/PIR foams were prepared by replacing 80% petrochemical‐based polyol with a hybrid poplar (HP) lignin, recovered via alkaline pretreatment, and also fraction this isolated Aqueous Lignin Purification Hot Agents (ALPHA) process.
