Morphology and Physico-Mechanical Threshold of α-Cellulose as Filler in an E-SBR Composite.

In the current context of green mobility and sustainability, the use of new generation natural fillers, namely, α-cellulose, has gained significant recognition. The presence of hydroxyl groups on α-cellulose has generated immense eagerness to map its potency as filler in an elastomeric composite. In the present work, α-cellulose-emulsion-grade styrene butadiene rubber (E-SBR) composite is prepared by conventional rubber processing method by using variable proportions of α-cellulose (1 to 40 phr) to assess its reinforce ability. Rheological, physical, visco-elastic and dynamic-mechanical behavior have clearly established that 10 phr loading of α-cellulose can be considered as an optimized dosage in terms of performance parameters. Morphological characterization with the aid of scanning electron microscope (SEM) and transmission electron microscopy (TEM) also substantiated that composite with 10 phr loading of α-cellulose has achieved the morphological threshold. With this background, synthetic filler (silica) is substituted by green filler (α-cellulose) in an E-SBR-based composite. Characterization of the compound has clearly established the reinforcement ability of α-cellulose.

Recurrent aggressive angiomyxoma of the vulva - a rare presentation.

We describe here a case of a 38-year-old lady presenting with a about 5x4cm in size swelling on the left labia majora. She had similar type of swelling 2 years back which was treated surgically. FNAC report of the present mass revealed angiomyxoma. In view of its' recurrent nature wide local surgical excision of the mass was done. Histopathology report confirmed the diagnosis of angiomyxoma. The lady is under follow up and there is no further recurrence till date.

Omental evisceration after cesarean section: safety of peritoneal nonclosure technique.

A case of omental prolapse presented to us on the fifteenth postoperative day following an uneventful Cesarean section. A rare complication as such questions the safety of peritoneal nonclosure that has been adopted by obstetricians in recent times.
