The aim of this paper is to identify a technique to detoxify the industrial waste water using metal oxide nanoparticles. Waste water from manufacturing or chemical processes in industries contributes to water pollution. Industrial waste water usually contains specific and readily identifiable chemical compounds. It destroys aquatic life and reduces its reproductive ability. Eventually it is hazardous to human life. Most major industries have treatment facilities for industrial effluents but this is not the case with small-scale industries, which cannot afford enormous investments in pollution control equipment. In this paper, an experimental study was conducted to study the effect of titanium dioxide and ferric oxide nanoparticles in detoxification of industrial waste water. Here the adsorption property of these nanoparticles was used for the detoxification of industrial waste water. The nanomaterials were synthesized using high energy ball milling machine and the characterization was done through scanning electron microscopy. After the preparation, these Nano sized titanium dioxide and ferric oxide powder were introduced to the pretested waste water. Due to the adsorption property of these nanomaterials, it is observed that the contaminants like sulphate, cadmium, lead and chlorides are adsorbed to some extent.
The aim of the study was to investigate the relationship between Gastro-esophageal reflux diseases (GERD) related symptoms and psychological symptomatology, as well as clinically diagnosed generalized anxiety disorder (GAD) or panic disorder (PD) and effectiveness of Sertraline and benzodiazepines in controlling these conditions. Methodology: A 6 months prospective study was conducted in gastroenterology outpatient department of a tertiary care referral hospital. Refractory GERD was diagnosed by assessing proton pump inhibitor failure over 4 week trial of standard doses of PPIs. Therapy with Benzodiazepines and Sertraline was initiated in patients with refractory GERD having panic and anxiety symptoms associated with refractory GERD. Effectiveness of the therapy was measured using panic and agoraphobia scale and Hamilton anxiety scale. Reduction in the severity of GERD symptoms was assessed using GERD-Health related quality of life scale. Results: The occurrence of PD or GAD in patients with refractory GERD in our sample was found to be 68% and 32% respectively. There was a significant decrease in the score of GERD HRQOL after the administration of sertraline and benzodiazepines when compared to the score of GERD HRQOL before administration of interventional drugs (p = 0.001). Conclusion: Our study investigated the role of anxiety and panic in refractory GERD and their effect on quality of life. The results indicated that quality of life of patients were highly improved as indicated by severity scores after administration with sertraline and benzodiazepines. The novel therapy of sertraline and benzodiazepines are highly effective in controlling reflux like symptoms and coexisting anxiety and panic disorder in refractory GERD.
The vision of this paper is to investigate and introduce a technique to decontaminate, one of the most essential commodities of life that is, water. The requirement of water for an individual varies from a minimum of 8 liters per day for drinking and cooking to about 20-50 liter per day for other daily needs. Unfortunately, about half of a billion people face the problem of water scarcity throughout the year. The treatment of wastewater namely sewage water can reduce these concerns however; the traditional methods of treatment are not efficient enough to completely remove the emerging pollutants. In this paper an experimental study was conducted for the effect of nano-sized materials on the purification of sewage water. As a matter of fact, various nano-materials have been prepared and used for the removal of contaminants from water. Herein the mechanism of adsorption was taken in to consideration were manganese dioxide and ferric oxide nano-particles were utilized as an adsorbent for decontamination of sewage water. The nano-materials were synthesized by means of planetary ball mills and characterization was done through scanning electron microscope. Then the prepared nano-particles were introduced in to the pre-tested water samples for contaminant adsorption. It was observed that the nano-materials can adsorb contaminants like zinc, magnesium, cadmium, chlorides & sulphates to some extent. In addition to this, the treated water shows excellent water quality standards.
