Applied and Environmental Microbiology Journal: A Bibliometric Perception

This study evaluates the Applied and Environmental Microbiology Journal (AEMJ). It is a biweekly peer-reviewed scientific journal published by American Society for Microbiology. It was established in 1953 as Applied Microbiology and obtained its current name in 1975. The American Society for Microbiology is the largest single life science, society, composed of over 47,000 scientists and health professionals. ASM\u27s mission is to promote and move forward the microbial sciences. The present bibliometrics study was 15291 scholarly research articles published in ‘Applied and Environmental Microbiology Journal, during the period 2001-2015. The collected data were analyzed with the help of ‘Bibexcel tool’. The references were collected from Mendeley. The learning also applied statistical tools such as, block wise distribution, Key word wise analysis, Country Collaboration and BRICS country collaboration

Laceability properties in the image graph of Prism graphs

A connected graph G is termed Hamiltonian-t-laceable if there exists in it a Hamiltonian path between every pair of vertices u and v with the property d(u, v) = t, 1 ≤ t ≤ diam(G), where t is a positive integer. In this paper, we establish laceability properties in the image graph of Prism graph Im(Yn).Publisher's Versio

All India Institute of Medical Science has published highest journals compare with the other institutions

DESIGN AND IMPLEMENTATION OF AUTOMATEDCLEANING OF CEILING FAN

The main objective of the project is to reduce the human effort and sluggishness of human when the operation is in large scale and to avoid the risk in case of any accidents. The proposed system that is portable and ensure regular cleaning of the ceiling fan using some mechanical setup such as scissor lift, lead screw whose movements are controlled by microcontroller which controls a pneumatic control and some cleaning mechanisms

Large scale farming of green mussel in Ashtamudi Lake, Kerala

Green mussel, Perna viridis, farming is spreading fast in the lower stretches of Ashtamudi Lake in Kollam district of Southern Kerala. Huge demand for green mussel in the northern part of Kerala has resulted in significant increase in its price. The price has increased to ` 10,000 per gunny bag of 70 kg for medium sized mussel (50-100 mm) whereas larger ones (120 -150 mm) fetch prices as high as ` 400 per kg (8 pieces). This has prompted local fishermen to try mussel farming using on bottom method of mussel culture which some farmers practiced earlier with locally available seed

Assessment of Peri-Implant Marginal Bone Level in Single Crowns Supported by Short Dental Implants: A Cone Beam Computed Tomography (CBCT) study

BACKGROUND AND OBJECTIVES: The purpose of this study is to clinically assess and compare the peri-implant marginal bone level in single crowns supported by short dental implants for a period of 1 year at regular 3 months time interval. MATERIALS AND METHODS: 14 subjects in age range of 18-55 years, with at least one missing maxillary/ mandibular posterior tooth were selected and received 14 short dental implants. Clinical parameters namely the modified plaque index, gingival index, probing depth, implant mobility scale were recorded. The radiographic parameter, bone loss was measured at 4 sites namely mesial horizontal, mesial vertical, distal horizontal, distal vertical by using CBCT. All the parameters were recorded before and after implant placement and at 3 months interval till one year. CBCT analysis will be done at baseline, 3 months (the time of crown placement), 9 months (after crown placement) to assess the peri-implant marginal bone level changes around implants. RESULTS: The mean bone loss at the mesial horizontal site was 1.86 ± 0.32 mm, mesial vertical site was 1.73 ± 0.34 mm, distal horizontal site was 1.09 ± 0.45 mm, and distal vertical site was 0.81 ± 0.38 mm at 3 months. The mean bone loss at the mesial horizontal site was 1.81 ± 0.19 mm, mesial vertical site was 1.69 ± 0.27 mm, distal horizontal site was 1.06 ± 0.33 mm, and distal vertical site was 0.76 ± 0.29 mm at 12 months. The comparison of bone loss between 3 and 12 months at various sites (mesial horizontal, mesial vertical, distal horizontal, distal vertical) was done. The results showed significant differences (p≤ 0.05) for modified plaque index, gingival index, probing depth. The overall mean bone loss at 3 months was found to be 1.37 ± 0.57 mm. The overall mean bone loss at 12 months was found to be 1.33 ± 0.51 mm. The comparison of the overall mean bone loss at 3 months and 12 months was 1.37 ± 0.57 mm and 1.33 ± 0.51 mm respectively. CONCLUSION: With the limitation of the study, it was concluded that the characteristics of the implant surface may influence the survival rate of short dental implants with minimal peri- implant marginal bone loss

Green synthesis of silver nanoparticles using Datura stramonium leaf extract and assessment of their antibacterial activity

Silver nanoparticles of 15-20 nm size with spherical shape were synthesized from green synthesis method using Datura stramonium leaf extract. Synthesized Ag NPs were studied for their optical, structural, surface morphological and antibacterial properties. The optical study shows that the appearance of SPR peak at 444 nm in the absorption spectrum is affirming the formation of Ag NPs and its high intensity with narrowed width indicating the homogenous size and shape of the Ag NPs. Structural studies reveal the good crystalline nature of face center cubic structure of Ag crystal and preferentially oriented along (111) plane with average crystallite size of 18 nm. FTIR analysis exhibits the possible reducing biomolecules within the leaf extract. The well defined homogenous spherical shape of the Ag NPs is clearly observed from the TEM studies and lattice fringes spacing of 0.23 nm shows the high crystalline nature of the synthesized Ag NPs. EDAX profile affirms the Ag crystal by the presence of energy peak at 3 eV. The synthesized Ag NPs showed antibacterial activity against E. coli and S. aureus bacteria. However, well pronounced activity was observed against E. coli

Stoichiometry control of sputtered CuCl thin films: Influence on ultraviolet emission properties

We demonstrate that the chemical composition of the sputtered CuCl thin films could be finely controlled by adjusting the bias to the substrate. The films deposited without any intentional bias were Cl rich (CuCl1+x), a bias of −22 V yielded stoichiometric CuCl, and a further increase in the negative bias resulted in Cl deficient films (CuCl1−x). The crystalline and optical properties were found to be associated with the chemical composition. Cl rich films showed a deep level green emission at around 515 nm in addition to ultraviolet (UV) excitonic emission. The stoichiometric films have higher optical quality, exhibiting a sharp UV emission at around 385 nm at room temperature, compared to nonstoichiometric samples. Visible luminescence related to deep level defects was not observed in the stoichiometric films. Changes in energy of the flux from the target and the subsequent ion bombardment on the substrate surface are correlated with the variations in chemical composition and their impact on the film microstructure and UV emission

Emerging clam fishery in Muthalapozhi Estuary

Muthalapozhi Estuary is located in northern part of Thiruvananthapuram District, Kerala. Perunguzhi and Azhoor are commercial bivalve landing centers located along the Muthalapozhi Estuary, where large-scale clam exploitation has emerged during the recent past (Fig. 1). This new development is due to the increased domestic demand for clams in Karnataka, Goa and Maharashtra consequent to the decreased availability of clams in their traditional local clam fishing grounds
