Explain Hardness of Water

Explain Hardness of Water The water that occurs in nature always contains salts, which exist in water as positive and negative ions. The salinity of fresh water is 1000 mg/L (1L of water contains 1000 mg of various salts or ions). The typical cations present in natural water are sodium, potassium, calcium and magnesium; the most common anions are chloride, sulfate, bicarbonate, nitrates, etc. Hardness of water refers to presence of calcium and magnesium ions. When water is heated, the reaction (Tebbutt, 1999):

takes place. Calcium carbonate, unlikely other salts, is insoluble and forms precipitate. The precipitate is ...

Introduction

Polymerase Chain Reaction (PCR) is a very influential technique that helps in amplifying the specific segments of DNA. This biochemical procedure is performed in-vitro that is quite different from cloning. This technique is a fusion of synthesis protocol of distinct repeated segments of DNA and thermostable DNA polymerase application that has given scientists a very potent analytical, immunological and molecular technique used prevalently in clinical laboratory science (Garibyan & Avashia, 2013). PCR is based on three primary steps that include denaturation of the template into single strands, annealing ...

Liver is the largest ‘gland’ of the digestive system. It is located right under the dome of the diaphragm, coated by the capsule. It is distinguished the liver’s convex upper surface adjacent to the diaphragm, and a lower, downwardly facing and in contact with the back and abdominal organs. On the part of the upper surface of the liver it can be seen its right and left lobes, the boundary of which is the crescent liver ligament. To the lower surface of the right lobe there is a gallbladder, close to the deep groove of the liver there ...

Healthy behaviors play a key role in daily life. Yet, certain unhygienic practices tend to interfere with the health and induce a risk to the overall life. These practices could be high-fat diet, alcohol, and smoking. There is a need to know much about these. In such context, the present description deals with a topic “ What will kill you first, a smoking, a high-fat diet or alcohol?”.

Health -related risk factors:

A risk factor is any quality, trademark or presentation of a person that improves the probability of building up an ailment or damage. A few illustrations of the more vital danger elements ...

There are various types of these nanocontainers such as polymeric liposomal nanoparticles, carbon nanostructures, magnetic nanoparticles and polymeric micelles (Singh and Lillard, 2009; Zarogoulidis et al., 2012). The mode of action of these nanostructures on the target site and the molecular proceedings occurring during this process provides a mechanistic foundation for drug discovery against cancerous developments. The several considerable points that an anti-cancer agent should have are targeted delivery to the impacted cells, least activity loss, ...
