INVESTIGATION OF THE MINIMUM QUANTITY LUBRICATION GRINDING USING NANOFLUIDS

In the recent years a lot has been done to avoid the cutting fluids from the production. Dry cutting and semi-dry cutting such as minimum quantity lubrication (MQL) have been favored by the industry. However, one of the main limitations in the application of MQL is that the full mechanism has not yet been fully understood. This paper presents the effects of MQL on the grinding performance of ductile cast iron. Ductile cast iron as compared to completely dry and wet machining in terms of tool wear, surface roughness and cutting forces. It was also seen from the results that the substantial reduction in tool wears resulted in enhanced tool life and surface finish. Furthermore, MQL provides environment friendliness (maintaining neat, clean and dry working area, avoiding inconvenience and health hazards due to heat, smoke, fumes, gases, etc., and preventing pollution of the surroundings), and improves the machinability characteristics

COMPRES: a prospective postmarketing evaluation of the compression anastomosis ring CAR 27/ColonRing

AimPreclinical studies have suggested that nitinol-based compression anastomosis might be a viable solution to anastomotic leak following low anterior resection. A prospective multicentre open label study was therefore designed to evaluate the performance of the ColonRing(™) in (low) colorectal anastomosis.MethodThe primary outcome measure was anastomotic leakage. Patients were recruited at 13 different colorectal surgical units in Europe, the United States and Israel. Institutional review board approval was obtained.ResultsBetween 21 March 2010 and 3 August 2011, 266 patients completed the study protocol. The overall anastomotic leakage rate was 5.3% for all anastomoses, including a rate of 3.1% for low anastomoses. Septic anastomotic complications occurred in 8.3% of all anastomoses and 8.2% of low anastomoses.ConclusionNitinol compression anastomosis is safe, effective and easy to use and may offer an advantage for low colorectal anastomosis. A prospective randomized trial comparing ColonRing(™) with conventional stapling is needed
