Integration of the Hard Disk Controller (HOC) today has taken on an extensive amount of functionality. From the host interface, error correction code, disk sequencer, microprocessor(s), servo control logic, buffer controller, to the embedded memory, the HDC has become a true system on a chip. Depending on the product, embedded DRAM is used as buffering for data between the host and media and po...

Plasma electrolytic oxidation (PEO) was performed on a 1010 Aluminum alloy. To achieve thenanocomposite structure, Si3N4 nanoparticles were added into the electrolyte. In an alkaline aqueoussuspension (silicate-based), the effect of adding NiSO4 on the applied voltage, microstructure,composition, wear, and corrosion resistance of PEO coatings was investigated using ScanningElectron Microscopy (...

background and objective: early determination of antibacterial susceptibility increases the success of therapy, decreases unnecessary use of antibacterial agents and side-effects, and lowers the overall healthcare cost. materials and methods: a rapid colorimetric method for antibacterial susceptibility testing named qui-sensitest (inovative biotechnology organization, istanbul, turkey) was eval...

In many works on the material removal in the Chemical Mechanical Process (CMP), the effects of several process parameters have been addressed. However, a thorough understanding of the mechanisms of material removal and a model to correlate the process parameters to material removal rate (MRR) are still lacking. This appendix develops such models for polishing based on the results from the pin-o...

In this study, a hybrid material is produced, and the effect of different loads varying from 40 to 60 N against an EN-31 steel counter disk on its wear behavior under dry sliding conditions at room temperature studied. The tribological studied via pin-on-disk method analyzed using primary parameters, such as coefficient friction (COF), mass wear, specific rate. obtained results are compared wit...

A tamping machine is the key equipment of large coking coal cake forming in steelmaking industry, where loose compacted into a by reciprocating movement its hammer. In long-term friction process, third particle attached to surface pair hammer lifting mechanism often causes slip and wear plate, resulting an insufficient height hammer, uneven work collapse other problems. order avoid adverse effe...

objective(s) the aim of this study was to investigate the presence of per-1-type esbls in drug resistant pseudomonas aeruginosa isolates. materials and methods during one-year period (2008-2009), following isolation and identification of 56 p. aeruginosa, the e-test method was performed for determination of minimal inhibitory concentration of ceftazidim. the isolates that they had mic≥16 µg/ml ...
