Electromagnetic Compatibility: A Mechanical Engineer ’s Perspective

Conclusion EMC should be considered first from an EE’s perspective, addressing concerns at the PCB level. MEs can get involved when enclosing the PCB or device. This is a collaborative effort. Both specialties should work through planning and execution. The ability to leverage a range of materials and components for EM enclosures allows engineers to make informed choices to meet the EMC requirements of a device. When considered at early stages, engineers can make EM an integral part of the design approach.

Publication date: Available online 21 January 2020Source: Urology Case ReportsAuthor(s): Joseph Santiapillai, Sachin AgrawalAbstractA 61 year old gentleman had a large renal cyst, thought to be causing a ‘pseudo-hydrocalyx’ leading to recurrent stones. Definitive treatment with laparoscopic deroofing was planned, however intra-operatively this was abandoned due to complex anatomy and scared adherent tissue. Patient went on to have a flexible ureteroscopy and ‘through and through’ puncture of an intrarenal cyst with PCNL to treat his stones and renal cyst simultaneously. CT scan 12 months later showe...

Conclusions: This is the first time that the extent and plausible effects of allogenic blood transfusions during NAC is examined in MIBC. Data suggest that there may be an association between blood transfusion and poor pathological and oncological outcome. Firm conclusions are difficult to draw due to few study participants and the retrospective nature of the study. PMID: 31960752 [PubMed - as supplied by publisher]

Publication date: Available online 21 January 2020Source: Materials Today: ProceedingsAuthor(s): V. Uma Varun, B. Rajesh Kumar, Krishna C. EtikaAbstractElectromagnetic interference (EMI) is a phenomenon where one electromagnetic field interacts with another, generating disturbances in both the fields. The electromagnetic interference (EMI) issue is of grave concern due to a rampant increase in wireless devices and increased sensitivity of electronic gadgets. Conductive polymer nanocomposites have been extensively used as an alternative to metals used traditionally for EMI shielding applications. In this paper, the influenc...

Measurements were taken with scanning transmission electron microscopy (FEI Versa 3d), energy dispersive X-ray (EDAX Apollo-X), and thermographic analysis (NETZSCH STA 449 F3 Jupiter). The results show the temperature ranges at which the chem...

Shongwe, Peter A. OlubambiAbstractMulti-walled carbon nanotubes (MWCNTs) are remarkable reinforcing material with magnificent mechanical features. The presences of sp2 C-C networks in their shells have been responsible for their wide-ranging mechanical abilities. MWCNT are generally known to agglomerate because of the existence of Van der Waals forces, which results in processing challenges during dispersion in metal matrices. In the pr...
