BACKGROUND Rupture of a saccular intracranial aneurysm (sIA) causes an often fatal subarachnoid hemorrhage (SAH). Why some sIAs rupture remains unknown. Since sIA walls bear some histological similarities with early atherosclerotic lesions, we hypothesized that accumulation and oxidation of lipids might occur in the sIA wall and might associate with sIA wall degeneration. Tissue samples from sI...

The overall goal of this study is to gain an insight into the load sharing aspect between oriented strand board OSB and gypsum wall board GWB in shear wall assembly during racking load. Sixteen standard 2,440 2,440 mm walls were tested monotonically, in total, out of which 11 Type A were sheathed on both sides OSB on one side and GWB on the other , while five walls were tested without GWB Type ...

Dear Editor, A 20-year-old normotensive male presented with sudden onset of near syncope, chest discomfort and dyspnoea. The patient has no known cardiovascular risk factors, including history of smoking, diabetes mellitus, dyslipidaemia and positive family history of ischaemic heart disease. Electrocardiogram (ECG) showed ST-elevation in the anterior and inferior leads (Panel A). Total white b...

The application of circular aperture frequency selective surface (FSS) for the enhancement of electromagnetic performance of monolithic half-wave radome is presented. The performance parameters of the circular aperture type FSS embedded radome panel are computed based on equivalent transmission line method in conjunction with equivalent circuit method (ECM). The EM analysis shows that the circu...

The requirements for plasma and first wall measurements on ITER, and the planned ITER diagnostic system, have been reviewed as part of the ITER design review process by a panel of experts experienced in operating modern tokamaks. The review panel recommended some changes in both the measurement requirements and the diagnostic system. These changes have been largely adopted and a new baseline di...

Adrenocortical carcinoma is an uncommon and aggressivemalignancy. Despite a high frequency of metastasis, cutaneousmetastasis of adrenocortical carcinoma is rare with only isolatedcase reports. Its diagnosis can be challenging based solely onhistopathological findings. Yet, the clinical history in combinationwith an immunohistochemical panel consisting of inhibin,vimentin, chromogranin, synapto...

The paper addresses the active control of the sound transmission through a double panel partition. A literature survey indicates that active cavity control is much more efficient than active structural control. The vibro-acoustic behaviour of the double wall is analysed in light of this observation. This analysis shows that the sound transmission through the double panel is larger than that thr...
