BACKGROUND Fidelity to the treatment protocol is key to successful trials but often problematic. This article reports the staff's views on delivering a complex rehabilitation intervention: patient-led therapy during inpatient stroke care. METHODS An exploratory qualitative study using focus groups with staff involved in a multicenter (n = 12) feasibility trial of patient-led therapy (the MAES...

Treatment of human promonocytic leukemic cell line U937 with mild hyperthermia in the temperature range of 40-43°C resulted in differentiation of these cells into monocyte/macrophage-like cells in a heat dose and time dependent manner. This process was accompanied by marked morphological, functional and proliferational changes. U937 cells which normally grow in supension in the logarithmic...

The effect of T6 heat treatment on the microstructure and wear behavior of Al-332 piston alloy containing 1.2wt% iron was investigated. The results showed that the T6 heat treatment changed the morphology of acicular eutectic Si particles to a more spherical form. The heat treatment also reduced the average length and blunted the needle-like ?- phase intermetallics through dissolution and fragm...

Rene-80 nickel-base superalloy as an alloy for production of the jet turbine blades shows high mechanical properties as well as microstructure stability during the high temperature engine operation. In this research, age hardening heat treatment cycle was done on the as-cast Rene-80 superalloy. In the following, microstructure, elemental analysis of phases and macro-hardness of the alloy before...

cacl2 treatment followed by heat shock is the most common method for artificial transformation. here, the cells were transformed using cacl2 treatment either with heat shock (standard protocol) or without heat shock (lab protocol) to comprehend the difference in transformation efficiency. the bl21 strain of escherichia coli (e. coli) was being susceptible using cacl2 treatment. some cells were ...

copper matrix composite reinforced by 1wt.% tib2 particles was prepared using in situ reaction of cu-1.4wt.% ti and cu-0.7wt.% b by rapid solidification and subsequent heat treatment for 1-20 hrs at 900ºc. high-resolution transmission electron microscopy (hrtem) characterization showed that primary tib2 particles were formed in liquid copper. heat treatment of as-solidified samples led to the f...
