Adsorption properties of Biomass Ash/ Graphene Oxide Composite for the Removal of Copper from Industrial Waste Water

Biomass ash is a complex inorganic-organic mixture with polycomponent, heterogenous or byproduct from biomass feedstock shows adsorption capacity for heavy metals and could be economical and environment friendly adsorbent. Graphene oxide (GO) are efficient adsorbent for removal of dyes, metal ions and toxic compounds. When biomass ash is used as composite formation along with Graphene Oxide then its adsorption capacity is enhanced. In the present work, Biomass ash on Graphene oxide base composite adsorbent (GO-g-BA) is synthesized for the effective removal of Cu (II) ions present in industrial waste water. They were characterized by FTIR, UV, FESEM and adsorption was studied by employing AAS with variables like pH. The results showed that BA-g-GO composite is an efficient adsorbent with 55.7 % for Cu(II) at pH 4.5. GO-g-BA composite was significant adsorbent for the removal of Cu(II) ions present in wastewater.

Green synthesis of copper (II) oxidenanoparticles (CuONPS) using leaves extract of Urtica dioica, Characterisations and antimicrobial activity

Recently, the applications of green synthetic processes in field of biological, chemical and pharmacological sciences have achieved essential roles. One of the major applications of green chemistry is the synthesis of zero valent metal and metal oxide nanoparticles using natural and abundant biologicalmaterials. In the present study, we have carried out the successful synthesis of copper (II) oxide nanoparticles (CuONPS) by using the leaf extract of Urtica dioica and formation of nanoparticles confirmed by a visual color change of the solution and then UV-Visible spectroscopy. The synthetic method was found very low cost, effective, efficient and eco-friendly. The synthesised nanoparticles have been characterised by using different analytical methods such as FTIR, UV-Visible, powder XRD and FESEM. The antibacterial activity of CuONPSwas checked by well diffusion method against S. aureus, S. mutans and E. coli. The maximum zone of inhibition was found for S. mutans after incubation period and at specific dosage of copper nanoparticles.

Peroxynitrite-induced oxidation and nitration products of Penciclovir: Structures and mechanisms of product formation

Peroxynitrite is a very good oxidizing agent which is formed by the reaction of nitric oxide with super oxide. There are so many works are reported which clearly indicate that peroxynitrite react with lipid protein and DNA. In our present work we report the oxidation of a very well known antiviral drug penciclovir by peroxynitrite. The oxidation of our selected drug was achieved by refluxing the drug with sodium nitrite, the progress of the reaction was monitored by thin layer chromatography and the product of the reaction was isolated by column chromatography. We also purposed the probable mechanism of the formation of different product.

Current Scenario on Neural tissue engineering

Worldwide millions of people suffer from nerve tissue injury- SCI (Spinal Cord Injury) that will result paralysis and experience of life-threatening problems. Till date there are different methods have been described to be effective in the treatment of SCI but there is no remedy available for full functional recovery of SCI. Stem cells and tissue specific growth factors entrapped matrixes along with the tissue engineering principle are the used for the treatments and for repairing SCI. Although these techniques overcome the limitation of traditional clinical methods but still they cannot restore the bio-functionality of the regenerated tissue after the injury. Therefore, the major challenge that is faced by the biomedical experts is to repair and regenerated a structural bio-functional damaged nerve tissue.

Removal of Empty Bands from Speech Signals in Hindi

In order to provide speech analysis, speech production and perception can be exploited with the help of various speech processing applications. Few properties or features can be extracted from speech signal S(n) with the help of speech analysis. With the objective of simplifying the speech signal and for removing the redundancy present within the speech signal, the transformation of S(n) is done into another signal. In this research work, the novel technique is proposed to remove empty bands from the speech signal. The proposed technique is based on the threshold value for the removal of empty bands. In the proposed technique, the frequency of each band is calculated and a band which has frequency below threshold value is removed from the signal. The performance of the proposed technique is tested in MATLAB and it is analyzed that proposed technique performs well in terms speech enhancement.

 Key words: Empty bands, LDA.

Comparative Evaluation of Various Brands Ciprofloxacin HCI Tablets

Ciprofloxacin HCI, is a highly popular antibacterial agent in the third world countries including India. Many companies are engaged in manufacturing and marketing the brands, purchasing the basic drug from the core suppliers. Often these brands vary in cost and companies usually claim superiority of their product to justify the higher price. There is a possibility that products containing same amount of basic drug are therapeutically equivalent. So, if it can be proved that the different brands are therapeutically equivalent, they can be substituted for each in prescription and patient can be take advantage of an economic dosage regimen. This could be achieved by assessing physicochemical equivalence of different brands of the drug. Assessment may include the evaluation of uniformity of weight, friability, hardness, disintegration and dissolution tests as well as chemical assay of tablets.

Low Temperature Graphene-Like Film Growth By Microwave Plasma Enhance Chemical Vapor Deposition Technique

Multilayer graphene like (MLG) film were grown on copper substrates by the microwave plasma enhanced chemical vapor deposition (MW PECVD) technique at low pressure of ~ 5.5 x 10-2 Torr. Copper has been used as catalyst substrate for deposition. The growth temperature was found to be 750 ºC. The precursor gas methane was found to dissociate at low temperature with assist of plasma. The MLG films were removed from copper with the help of ferric chloride solution and were transferred to glass substrate. The appearance of 2D band in Raman spectra confirms the growth of graphene film. The highest I2D/IG ratio was found to be 0.70, which confirms few layer graphene.

Application of Mathematical Modeling in Population forecasting

In the present paper we have to study future population forecasting in India by the geometrical model used to census population data. Design is based on the projected population of India, estimated for the design period. Changes in population over the years occur, and the system should be designed into account of the population at the end of the design period. Factors affecting changes in population are increase due to births, decrease due to deaths, increase and decrease due to the migration and increase due to the annexation. The present and past population record in India can be obtained from the census population records. After collecting these population records, the population at the end of design period is predicted using various geometrical methods as suitable for the growth pattern.

A Review on Novel Edible Coatings for fresh- cut Fruit and Vegetable

Consumption of F & V has been associated with diverse health interest. Fruits and vegetables can be consumed in both forms   either processed or fresh.   Consumption & production of minimal processed foods has acquired increasing demand in the market. Due to changes in life -style of consumers fresh-cut F &V are gaining popularity. However, it summons for fresh or minimal processed F & V   by maintaining the properties of fresh-cut products for a extended time period.  Fresh-cut products has a much bigger surface to cut & accordingly having less shelf-life.  Rejection of the product by consumers is due to some quality issues such as flavor, color, firmness, juiciness & loss of moisture lead to shorter shelf- life. Recent  Developments in edible coatings & packaging technology  for foods have shown encouraging  results in prolonging  the shelf-life of fresh-cut F & V . A solution for preserving the fruits & vegetable is coating with edible films. Therefore, this article reviews the scope of fresh-cut fruits & vegetables and extending its shelf-life by means of  edible coating. Edible coatings can be composed  of different substances of various types. These can be grouped together into proteins, carbs &lipids-based coatings &their characteristics.
