The question about physician-assisted suicide in many societies around the world remains difficult, except some European countries such as Belgium and the Netherlands, and some states in USA - Oregon, Washington and Montana where this former restriction was legalized. Nowadays, other countries and the rest of states in the U.S. facing dilemma rather to leave PAS illegal, or change existing law into legal practice. In “Introduction” of the book Ethical Issues in Modern Medicine by Bonnie Steinbock, John D. Arras, and Alex John London, a fictional Dr. Deborah Brody raises the problem of her ill patient, Mr. Lasken, who asked the doctor to help him relieve his sufferings through a lethal injection. Dr. Brody opened…

Concrete is a composite product obtained artificially by hardening of mixture of cement, sand, gravel and water in pre-determined proportions. When these ingredients are mixed, they form a plastic mass which can be moulded in desired shape. It gets hardened into hard solid mass. Water is one of the important ingredients of concrete. This is required not only for chemical reaction, but also for curing purposes. The chemical reaction of cement and water, in the mix, is relatively slow and requires time and favorable temperature for its completion. Depending on the quality and proportions of the ingredients used in the mix, the properties of concrete has enough strength in compression, but has little strength in tension. Due to this, concrete as such is weak in bending, shear and torsion. Hence the use of plain concrete is limited to applications where great compressive strength is the main requirement and where tensile stresses are either totally absent or are extremely low.…

ratio but this workability is sometimes lost rapidly in the first hour after contact between the cement and water. This is especially the case for naphthalene-based and melamine-based superplasticizers when used with the so called incompatible cements. It is possible to reasonably predict the rheological behavior of a given Portland cement when used with a naphthalene-based superplasticizer once the physico-chemical composition and the properties of the clinker, of the cement, and of the superplasticizer are known. Different Portland cements, having a wide range of C3A contents (6.0 to 11.8%) and SO3 contents (0.09 to 2.90%), made with clinkers having a wide range of alkali contents (0.07 to 0.87% of Na2Oeq), have been selected to highlight the key cement factors that control the compatibility between ordinary Portland cements and the naphthalene-based superplasticizers. The soluble alkalis (in fact the soluble SO4 2- ions from alkalis), the fineness, the C3A content, and the type of CaSO4 of the cement are among the key cement factors that control the rheological behavior of a superplasicized cement paste and concrete. An optimum amount of soluble alkalis content exists and ranges between 0.4 and 0.6% of Na2Oeq in the cement. The rate of the naphthalene based superplasticizers’ adsorption on the cement particles and cement hydrates, which is influenced by these parameters, controls the loss of fluidity of the concrete. Moreover, this study has shown that concrete made with cements that have a low soluble alkali content not only lose their slump when under dosed in super plasticizer but also present severe segregation and bleeding when the dosage of the super plasticizer is slightly higher than the saturation point. In…

A cement mill is the equipment used to grind the hard, nodular clinker from the cement kiln into the fine grey powder that is cement. Most cement is currently ground in ball mills and also vertical roller mills which are more effective than ball mills. Cement mill is not only suitable for over-flow grinding, but applicable for cyclic closed-flow grinding together with powder collector. We all know that the cement mill plays an important role in the mining industry. It’s necessary for customers to learn to use the cement mill properly to realize the highest production. To handle well the temperature problem will be one of the most concerned problems for us.If the temperature inside the cement mill is too high, adverse influences will be brought according to our experts. Here we will talk about the damage of high temperature of the working cement mill.1.The high temperature of cement will influence its workability because it will make the cement concrete to produce differential temperature stress which will cause concrete cracking.2.It will seriously influence the storage, packaging and transportation of cement, and make the packing bag become crisp, thus increasing the breakage rate and worsening the working environment of the labors.3.It is harmful to the grinding mill. It will raise the temperature of the bearing and weaken the lubrication effect, and make the cylinder produce some thermal stress which will cause the screws of the lining board to break off; and what is more, the grinding mill will not run continuously, thus damaging the equipment.4.It will increase the temperature of the materials that go into the powder concentrator, so that the adhesion of the internal wall and the fan blade of the powder concentrator will increase too.5.It will cause the gypsum to dehydrate to semi-hydrated gypsum and even anhydrite and cause the cement to falsely curdle which will influence the quality of cement and make the cement that is stored cake.At the present, Fote…
