This study treats one important aspect of starch-filled rubber compounds which is their rheological behavior. Starch-based SBR1712 masterbatches resulting from various formulations were prepared using a mini two roll mill and an internal mixer (Plastograph Brabender).The content in starch was varied from 0 to 50 phr. The effect of starch content on the rheological behavior was ev...

background. orthodontic mini-implants provide skeletal anchorage for tooth movement. there are two designs of mini-implants, tapered and cylindrical, which exhibit different clinical characteristics, including possible micro-damage to cor-tical bone. complications such as peri-implantitis and pain after mini-implant placement are common. the aim of this study was to evaluate the effect of mini-...

this study was conducted to evaluate different nutrient solutions effects on agria potato mini-tubers production under aeroponic system. the experiment was conducted in the laboratory and greenhouse of ardabil sabalan behparvar company in 2013. four recommended nutrient solutions including: lommen and struik (1992), kang and han (2005), otazu (2010) and hoagland and arnon (1950) were used in a ...

PURPOSE The use of a 2.0-mm locking plate system was evaluated in mandibular surgery. PATIENTS AND METHODS 53 patients (42 male, 11 female) with a total of 56 mandibular fractures were treated with a 2.0-mm mini-locking-plate system and retrospectively examined. Gender, age, cause of fracture, surgical access, classification of fractures, osteosynthesis, postsurgical findings and complication...

the effect of steel plate thickness on the repair effectiveness of rc beam is presented in this paper. a total of four beams were tested, one beam repaired by cfrp with a thickness of 1.2 mm and used as a control beam, and three beams repaired by a steel plate. steel plates with a thickness of 2 mm, 3 mm, and 4 mm were used in repairing the beams. the maximum load-carrying capacity, deflection ...

OBJECTIVES The aim of this study was to examine whether asymmetric loading influences macrophage elastase (MMP12) expression in different parts of a rat tail intervertebral disc and growth plate and if MMP12 expression is correlated with the severity of the deformity. METHODS A wedge deformity between the ninth and tenth tail vertebrae was produced with an Ilizarov-type mini external fixator ...

Objectives: We aimed to investigate the radiological and clinical results of transverse osteotomy fixation applications in rotation deformities due metacarpal malunion. Methods: A total 18 fingers from patients were enrolled study (14 males 4 females). The average age was 32.8 ± 14.4 years (range: 18-58 years). follow-up duration 19.7 7.9 months 7-36 months). All had a scissoring deformity whic...

conclusions the inhibition of mini-puberty period in male rats was demonstrated to have an effect on their testicular function to some extent. results serum t and lh levels peaked at two hours after birth, while fsh peaked at hour 0, and bilateral testicular weight peaked at four hours after birth. the rats that underwent ether inhalation five minutes after birth had markedly reduced serum horm...
