In this presentation, frst, the Internal Damping (I.D.) phenomena and related theories that have been previously reported in the literature for Metal Matrix Composites (M.M.C.s) are reviewed briefly. Then, the paper is focused on the transient ID phenomena. Especially, it is shown that a broad Iow temperature peak appears in the low frequency internal damping (ID) spectra of aluminium based mic...

Multiple myeloma is characterized by the clonal expansion of malignant plasma cells (multiple myeloma cells [MMCs]), in the bone marrow. Osteolytic bone lesions are detected in 80% of patients because of increased osteoclastic bone resorption and reduced osteoblastic bone formation. MMCs are found closely associated with sites of increased bone resorption. Osteoclasts strongly support MMC survi...

Farmed fish are exposed to a continuous antigenic pressure by microbial and environmental agents, which may lead to a condition of chronic inflammation. In view of the notion that polyphenols, largely contained in fruits and vegetables, are endowed with antioxidant and anti-inflammatory activities, farmed sea bass (Dicentrarchus labrax L.) have been administered with red grape polyphenol-enrich...

High-entropy alloy particles (HEAPs) can markedly enhance the mechanical properties of metal matrix composites (MMCs). In this study, AA5083/Al0.5CoCrFeNi HEAPs MMCs with different contents (0, 1, and 3 wt%) were prepared via a stir-casting, then these sheets hot rolled (573 K) cryorolled (77 K), respectively. The measured by tensile testing microhardness test. Additionally, their microstructur...

This study investigates the wear resistance of four AA6061 MMCs together with the monolithic AA6061 alloy, all in the T6 condition, using a pin-on-disc test. In addition to the widely studied 20 vol.% Saffil MMCs, the present investigation considered a hybrid of 11% Saffil + 20% Sic, and a high volume fraction Sic, MMC. AA6061 + 60% Sic,. The wear behaviour against P400 Sic grit adhesive bonded...

Phosphorylated methyl-CpG binding protein2 (p-MeCP2) suppresses the processing of several microRNAs (miRNAs). Homeo-domain interacting protein kinase2 (HIPK2) phosphorylates MeCP2, a known transcriptional repressor. However, it is not known if MeCP2 and HIPK2 are involved in processing of miRNAs implicated in diabetic nephropathy. p-MeCP2 and HIPK2 levels were significantly increased, but Seven...

Multiple myeloma is a plasma cell cancer with poor survival, characterized by the clonal expansion of multiple myeloma cells (MMC), primarily in the bone marrow. Novel compounds are currently tested in this disease, but partial or minor patients' responses are observed for most compounds used as a single agent. The design of predictors for drug efficacy could be most useful to better understand...

Alosetron (Lotronex) is a serotonin subtype 3 (5-HT3) receptor antagonist that alleviates symptoms of irritable bowel syndrome (IBS) in female patients. Alosetron may act centrally, involve the alteration of ascending pain sensation, or modulate peristaltic, secretory, or sensory function. To investigate further the mechanisms underlying its action and gender selectivity we recorded the effect ...

The AC voltage control of a DC/DC converter based on the modular multilevel converter (MMC) is considered under normal operation and during a local DC fault. By actively setting the AC voltage according to the two DC voltages of the DC/DC converter, the modulation index can be near unity, and the DC voltage is effectively utilized to output higher AC voltage. This significantly decreases submod...
