Mill is rather enhancing instead of contradicting his point of view of utilitarianism by the two claims stated above in the topic. There are two types of pleasures that he introduces here. "Pleasure, and freedom from pain" imply the lower pleasures which involved purely body sensations (Mill, p.187).

He was moving swiftly back and forth among the debris of his furniture, now and then staving chance fragments of it across the room with his foot; grinding a constant grist of curses through his set teeth; and halting every little while to deposit another handful of his hair on the pile which he had been building of it on the table.
Cyclodextrins as effective additives in AuNP-catalyzed reduction of nitrobenzene derivatives in a ball-mill S. Menuel, B. Lger, A. Addad, E. Monflier and F. Hapiot, Green Chem., 2016, 18, 5500 DOI: 10.1039/C6GC00770H To request permission to
2015/12/16The ball nose end mill was electro-polished using the optimized parameters which was obtained through performing the preliminary experiments on tungsten carbide coupons of size D6 20 mm. The effects of electro-polishing on the surface texture of the ball nose end mill were determined using surface texture examinations.
The CryoMill is a laboratory ball mill specifically designed for this application. It features an integrated cooling system which continually cools the grinding jar with liquid nitrogen before and during the grinding process. Thus, the sample is embrittled and volatile components are preserved. The liquid nitrogen is continually supplied from
Ball valves are shutoff valves that use a ball to stop or start the flow of fluid downstream of the valve. The ball, shown in Figure 7-1, performs the same function as the disc in other valves. As the valve handle is turned to open the valve, the ball rotates to a point where part or the entire hole that is machined through the ball is in line with the valve body inlet and outlet.

2015/11/13Subsequent hydrolytic desilylation and phosphate coupling were effected in one-pot using liquid-assisted grinding in a vibration ball mill. Novel 3′,5′- and 5′,5′-pyrophosphorothiolate-linked dinucleoside cap analogues were thereby prepared.
Modeling and optimization of a continuous bead milling process for bacterial cell lysis using response surface methodology
Bead mills when operated in a continuous mode substantiate to be economical, and more productive as compared to a batch mode process. In this study, the recovery of recombinant cholesterol oxidase (COD) was investigated and optimized using response surface methodology (RSM) based on Central Composite Design (CCD) in a continuous bead milling process.
A steel mill or steelworks is an industrial plant for the manufacture of steel. It may be an integrated steel works carrying out all steps of steelmaking from smelting iron ore to rolled product, but may also be a plant where steel semi-finished casting products are made from molten pig iron or from scrap.
