Water is the most v aluable, basic human need, prime natural resource and a precious asset. Water is indeed required in all aspect of life and health for domestic purposes, drinking, cooking, bathing, washing clothes, utensils, producing food, agricultural activity, energy generation, maintenance of environment and development for life. Water plays important role in several metabolic, physiological and other activities in human body as well as in other living beings ( m ittal and Arora, 2014)

Antimicrobial Efficacy of Green Silver Nanoparticles and Potential Implications for Human Health and the Environment

The beginnings of the applications of nanotechnology in the field of health sciences took place in early 2000s. There is a wide range of application of nanoparticles and its uses are emerging rapidly. Nanoparticle synthesis is usually carried out by various physical and chemical methods using various hazardous and toxic chemicals which may have adverse effect in the medical applications. Nevertheless, green synthesis approaches of producing silver nanoparticles are an alternative source of conventional method and is cost effective, environment friendly, easily scaled up for large scale synthesis and in this method there is no need to exploit high pressure, energy, temperature and toxic chemicals as in case of chemical and physical method. In this review, we report, some of the major applications of green synthesis of silver nanoparticles

CO to CO2 Using Magnesium Based Catalysts: An Overview

Stringent environmental re gulations have been adopted by the government in order to decrease the emission of vehicular exhaust such as S o x, N o x, C o and unb urned hydrocarbons. t herefore, the de velopment and exploration of catalysts started in the last century for the oxidation of carbon monoxide by different methods have attracted many researchers. t herefore, lar ge number of catalysts have been modified and tested for C o oxidation. t he de veloped catalysts have the ability of 100% conversion. Keeping in view of the literature accumulated in the last few decades for C o oxidation, Magnesium based catalysts ha ve been reported by many scientists for C o oxidation due to its unique characteristics such as high catalytic performance at low temperatures and good durability and stability toward C o oxidation. t his article represents a short re view in tabular form which facilitates a quick view on compounds that have been reported with magnesium previously

Exogenous Sulphur Dioxide Induced Changes in Superoxide Dismutase, Peroxidation and Non- Protein SH Content in Mung Bean (Vigna Radiata) Seedlings

This study investigated the effect of exogenous sulphur dioxide gas for different durations the superoxide dismutase, peroxidase, lipid peroxidation and non-protein SH content in mung bean (Vigna radiata) seedlings. It has been found that the activity of superoxide dismutase is enhanced at low concentration but decreased when the seedlings are exposed to higher concentration of SO 2 ; the peroxidase activity and lipid peroxidation decreased and the non-protein SH content increased significantly. The results indicate that superoxide dismutase, peroxidase, lipid peroxidation and non-protein SI-I content metabolisms are associated with the growth of the organism and are susceptible to alterations by exogenous sulphur dioxide stress

Electrophoretic Study of d-Block Metal Ions on Plain and Tri-n-Butylamine (TBA) Impregnated Titanium (IV) Tungstate Layers

RPTLE of ninteen d block metal ion studied on TBA impregnated titanium(IV)tungstate layer in nine solvent system among them three are complex forming acids OA,TA, CA to study the effect of complexation on migration. Electrophoretic migration also correlated with Ionc potential,Kd of metal ions and Ka of acids,pH of electrolytes.The spots are well defined in RPTLE and Mi is positiv

Low Voltage Thin Layer Electrophoresis of Anions on Silica Gel-G And Titanium (IV) Tungstate Layers

The low voltage thin layer electrophoresis of anions has been studied on Silica Gel-G and titanium (iv) tungstate layers in in v arious complexing acid media such as Oxalic acid (O.A), Citric acid(C.A), Tartaric acid (T.A) and Succinic acid (S.A).The electrophoretic migration of anions also correlated with lyotropic number, N. The Spots are well defined in electrophoresis

H2 - Y2 Reactions (Y = Cl, Br, I): A Comparative and Mechanistic Aspect

The reaction between hydrogen and chlorine shows resemblance to that between hydrogen and bromine but is considerably more complicated, owing to the larger number of elementary processes that play a significant part in it. The reaction scheme proposed for the hydrogen-chlorine reaction differs in several important respects from that for the hydrogen-bromine reaction. The main differences are seen to be (1) the inclusion of the reaction H + HBr → H2 + Br and the exclusion of H + HCl → H2 + Cl, and (2) the different chain-terminating steps, Br + Br → Br2 being assumed for bromine and the three processes H + O2, Cl + O2, and Cl + X in the chlorine reaction. The rather marked difference between the reactions of chlorine, bromine, and iodine with hydrogen is that the hydrogen-iodine reaction is elementary while the others are not

Synthesis, Characterization and Biological Evaluation of Some Novel Chalcone Derivatives Containing Imidazo[1,2-a]Pyridine Moiety

Chalcone was prepared by the condensation of arylmethyl ketone and arylaldehyde in the presence of alcoholic alkali. Present study describes the synthesis of a series of (2z)-3-[2-(4-chlorophenyl)-8-methyl imidazo[1,2-a] pyridine-3-yl]-1-substituted arylprop-2-en-1-one compounds (h) 1-9. The compounds were characterized by modern analytical techniques such as CHN analyses, IR, 1H NMR spectra and further supported by mass spectroscopy. All the title compounds were screened for their in vitro antibacterial and antifungal activity against B.coccus, S.aureus, Pseudomona, E.coli, A.niger, Ampicillin, Amoxicillin, Ciprofloxacin, Norfloxacin, Greseofulvin. Their minimum inhibitory concentrations (MIC) were determined. The results of antibacterial activity showed that compounds h 4, h 9 and antifungal activity compounds h 1, h 9 using standard drug

Quality of Water in and Around Chandigarh Region - A Review

It is well documented that water is an essential component for the survival of all living beings and development processes on earth. Water is used for domestic purposes, industrial processes and agriculture. All these processes require good quality water. River water and underground water is generally used for almost all these processes. So it is very important to know the water quality of sources time to time for the sustainable development. In this paper we have discussed the quality of ground water, surface water and river water of Chandigarh and nearby places such as Parwanoo, Panchkula, S.A.S. Nagar (Mohali) on the basis of reports available online. The different water quality parameters such as hardness, alkalinity, Ca2+, Mg2+, BOD, COD, TDS, pH, conductivity, temperature etc was considered for this review study. Although very few studies have been conducted to check the water quality of this area but on carefully reviewing the available reports and published work, it has been observed that the water quality in some of the places is below the standards of water quality prescribed by Bureau of Indian Standards (BIS). Proper functioning of Sewerage Treatment Plants (STPs) need to be checked and Industrial waste should be properly treated before going to the catchment areas

Treatment of Dental Caries by Ozone Therapy – A Review

Ozone, a powerful oxidizer effectively kills bacteria, fungi, viruses and parasites at a dramatically lower concentration and also has the capacity to stimulate blood circulation, platelets, and immune response. Ozone being biocompatible is used in all aspects of dentistry in gaseous, ozonated water and as ozonated oils. Ozone therapy is a well-established alternative and complementary therapy in most of the European countries. Treatment may be achieved by increasing the resistance of the tooth against the microbial activity and reducing the extent of microbial activity. In addition to the recent materials and techniques, the therapeutic actions of ozone may provide beneficial results by reducing the demineralization of the tooth. The treatment is completely painless and increases the patient’s acceptability and compliance with minimal adverse effects. In the present paper, a systematic review was performed on studies investigating the effects of ozone on oral tissues and microorganisms and unveil the uses of ozone in dentistry in all aspects
