The thermo-mechanical properties of carbon black reinforced natural and styrene butadiene rubbers are investigated under rapid adiabatic conditions. Eleven grades with varying surface area structure at 40 parts per hundred (phr) loading studied the unreinforced equivalents included for reference. results show a strong correlation modulus, mechanical hysteresis, temperature rise calculated cryst...

Neurogenic bladder , explanations follow in the text . i. Urge Incontinence manifesting as urgency and the urinary leakage even before individual reaches the toilet. ii. Over flow incontinence manifesting as involuntary release of urine from an overfull urinary bladder, often in the absence of any urge to urinate. iii. Dribbling incontinence , the patient is never dry a continuous leakage of ur...

The cough/laugh syndrome is characterized by the onset of severe headache immediately after an episode of coughing, laughing, or straining. It has been associated with pathologic changes in the posterior fossa, in particular, cerebellar tonsillar herniation or ectopia [1-3]. MR imaging is important in the evaluation of craniocervical anomalies, particularly Chiari malformations [4, 5]. We prese...

Dislocation slip is investigated in a metastable  titanium alloy with the Ti-23Nb-0.7Ta-2Zr0.4Si composition (at. %) by in situ straining experiments in a transmission electron microscope (TEM). Moving dislocations have a/2<111> Burgers vectors and glide in {110}, {112} or {123} planes. The mobility of screw dislocations is lowered by punctual defects and the existence of a stable and sessile ...

Pneumomediastinum and subcutaneous emphysema generally occurs following trauma to the esophagus or lung. It also occurs spontaneously in such situations of elevating intra-thoracic pressure as asthma, excessive coughing or forceful straining. We report here on the rare case of a man who experienced the signs of pneumomediastinum and subcutaneous emphysema after a prolonged bout of intractable h...
