Reference Based Study On Soundtrack (Music) Sustainable Solutions Using AI Techniques
No full textArtificial intelligence (AI) has been used in applications to alleviate certain problems throughout industry and academia. AI, like electricity or computers, is a general-purpose technology that has a multitude of applications. It has been used in fields of language translation, image recognition, credit scoring, e-commerce and other domains. Computer music is the application of computing technology in music composition, to help human composers create new music or to have computers independently create music, such as with algorithmic composition programs. It includes the theory and application of new and existing computer software technologies and basic aspects of music, such as sound synthesis, digital signal processing, sound design, sonic diffusion, acoustics, electrical engineering, and psychoacoustics. The field of computer music can trace its roots back to the origins of electronic music, and the first experiments and innovations with electronic instruments at the turn of the 20th century. In this paper we will study how AI is applied for sustainable music solutions
Molecular imprinting in monolayer surfaces
No full textA comprehensive report on molecularly imprinted monolayers (MIMs) is presented, but does not include bulk-polymer thin film coatings on surfaces, inorganic surface imprinting, polymer grafting and layer-by-layer methods. Due to difficulties in imprinting large molecules and obtaining fast binding responses with traditional network polymer materials, MIMs have been developed with the aim of enhancing mass-transfer of analytes in imprinted materials. Three approaches to MIM fabrication have been developed with respect to the formation of the pre-organized template-matrix complex. In the first approach, the molecular binding sites are formed in a monolayer on a glass or gold surface. The second approach uses a template-macromolecule complex to form binding sites in the solution phase that are immobilized onto a surface; and the third approach transfers an imprinted Langmuir film onto a gold surface. Mass transfer in these MIMs in most cases is on the order of minutes, and both small and large molecules (proteins) have been imprinted. Copyright © 2011 John Wiley & Sons, Ltd.

Interaction of polyalanine α-helix with carbon nanotube
No full textThe application of carbon nanotubes (CNT) in the area of biology such as Drug delivery vehicle and Biosensors calls for the basic understanding of the CNT's with biological macromolecules like proteins, DNA, Carbohydrates and lipids. CNT is known to be highly hydrophobic in nature. Our study reveals that the inherent hydrophobic nature of CNT is capable of disturbing the α-helical protein secondary structure. Thus our study provides mechanistic understanding of the loss in the α-helicity of the proteins in the presence of CNT. Our study reveals that the nanomaterials should be suitably modified for biological applications

No full textCatalyst Regeneration of RAP-Binder in Asphalt
No full textReclaimed Asphalt Pavement (RAP) binders are difficult to reuse because they often contain associated/aggregated molecules with very high molecular weights. This is due to the polarity gained during oxidative aging, causing the aggregation to occur. These high molecular weight components are responsible for RAP binder’s increased viscosity and certain deteriorated rheological properties. One strategy to reuse RAP binder is to mix it with virgin asphalt binder and use this partially recycled mixture in asphalt. The RAP binder is usually improved before mixing by the addition of rejuvenators, softening agents, softer binders, and antioxidants to the asphalt binder mix to rebalance their rheological properties. The purpose of this research was to study effective ways to incorporate RAP content in asphalt mixtures using a novel approach of introducing a catalyst that can modify the binder’s chemical composition; particularly to alter the oxidized molecules and reduce the number/content of aggregated structures. The use of a catalyst such as a Lewis acid to break the associated molecules in the RAP-binder is a new promising approach. The Lewis acids catalysts are known to catalyze the conversion of coal to liquid product, but the mechanism of action is not well understood. This report describes the result of our investigation into the effects of a Lewis acid catalyst such as Iron (III) chloride and Zinc chloride on the chemical composition of RAP-binder. The ultimate result is that Iron (III) chloride lowers the size of high molecular weight material when 2% w/w is used with RAP at 165 degrees Celsius for 30 minutes
Adsorption of chlorobenzene onto (5,5) armchair single-walled carbon nanotube and graphene sheet: toxicity versus adsorption strength
No full textAdsorption of the homologues series of chlorobenzenes (CBs) onto the surface of the (5,5) armchair single-walled carbon nanotube (SWCNT) and graphene (Graph) sheet has been investigated using density functional theory-based calculations, and the concomitant interaction between the CBs and SWCNT/Graph has also been characterized with the help of the Bader’s theory of atoms in molecules. Results reveal that interaction of CBs with the SWCNT and Graph enhances with the increase in the chlorine content. The adsorption of CBs on Graph is more favorable when compared with SWCNT. Evidence shows that the planar surface of the graphene facilitates the direct through-space interaction of the chlorine atoms of CBs with the aromatic surface. The π character of CBs governs the interaction process in the case of SWCNT. Findings from this study clearly demonstrate the importance of geometry (curved or planar) of the nanomaterial in the adsorption of aromatic pollutants. In addition, the inter-relationship between the electrophilicity index (a powerful conceptual DFT descriptor of toxicity of CBs) and the interaction energy (adsorption capacity) has also been derived
Length-dependent stability of α-helical peptide upon adsorption to single-walled carbon nanotube
No full textEarlier studies have shown that the helical content of α-helical peptide decreases upon its interaction with carbon nanotube (CNT). Further, the length of the α-helix varies from few residues in the small globular protein to several number of residues in structural and membrane proteins. In structural and membrane proteins, helices are widely present as the supercoil i.e., helical bundles. Thus, in this study, the length-dependent interaction pattern of α-helical peptides with CNT and the stability of isolated α-helical fragment versus supercoiled helical bundle upon interaction with CNT have been investigated using classical molecular dynamics (MD) simulation. Results reveal that the disruption in the helical motif on interaction with CNT is directly proportional to the length of the helix. Also it is found that the shorter helix does not undergo noticeable changes in the helicity upon adsorption with CNT. On the other hand, helicity of longer peptides is considerably affected by its interaction with CNT. In contrast to the known fact that the stability of the helix increases with its length, the disruption in the helical peptide increases with its length upon its interaction with CNT. Comparison of results shows that structural changes in the isolated helical fragment are higher than that in supercoiled helix. In fact, helical chain in supercoiled bundle does not undergo significant changes in the helicity upon interaction with CNT. Both the length of the helical peptide and the inherent stability of the helical unit in the supercoiled helix influence the interaction pattern with the CNT
Metagenomic data of vertical distribution and abundance of bacterial diversity in the hypersaline sediments of Mad Boon-mangrove ecosystem, Bay of Bengal
No full textBacterial diversity studies in hypersaline soil often yield novel organisms and contribute to our understanding of this extreme environment. Soil from Mad Boon is previously uncharacterized, with dense mangrove forest in one side and hypersaline soil in another side of backwater located in Southeast coast of Tamil Nadu, India. We surveyed to characterize the structure and diversity of the bacterial community. Samples were collected in a partially vegetated upland, exposed backwater sedimentation and water-logged location. In this study, we investigate the bacterial community structure using pyrosequence analysis of the V5- V9 gene region. After quality checks a total of 3919, 7298 and 7399 reads were obtained. About 42 phyla were observed, among them Proteobacteria were dominant phylum followed by Acidobacteria, Firmicutes and Chloroflexi. Classes including Deltaproteobacteria and Gammaproteobacteriawere observed. All sequences generated in this study were submitted to NCBI SRA under the accession numbers SRR627695, SRR63011 and SRR631012
