We experimentally studied the thermal runawayinitiating at a low critical current ( I c ) part. This part is determined by combination of two reasons in real coil: (a) unavoidable defects caused manufacturing process, which reduce local curr...

L aparoscopic suturing presents an important skills barrier to developing a laparoscopic surgical practice. The formation of a slip-knot greatly assists in approximating tissue that may initially be under tension or when the suture material is difficult to tie owing to memory (the property of resisting deformation). I describe here a technique that allows the surgeon to fashion an intracorporea...

Hypothesis / aims of study The use of polypropylene mesh to repair urinary incontinence and vaginal prolapse has decreased the recurrence of these conditions. However, it has also been related to specific complications such as vaginal erosions (1). Nitric oxide (NO) can modulate angiogenesis, vasodilation and fibroblastic reaction (2). We studied the effect of a NO donor (S-nitrosoglutathione G...

Some exploratory work on creep and inverse creep in nylon 6 monofilament, polyester multifilament yarn and wool and cotton spun yarns has been presented. It is observed that the extent of creep and inverse creep differs from material to material and depends on the initial stress. Cotton shows minimum inverse creep while nylon shows maximum inverse creep. Wool and polyester have intermediate inv...
