Improvement of Mechanical, Thermal and Optical Properties of Barium Mixed Cobalt Tartrate Hydrate Crystals Grown by Gel Method

In this present work, CTH and BCTH crystals have been prepared by gel technique by using single diffusion method at room temperature. The as grown crystals were characterized by using XRD, FT-IR, UV, TG / DTA and Micro hardness studies. X-ray powder diffraction results analyzed by using suitable software suggest that a CTH and BCTH crystals belong to cubic crystal system. The unit cell volume is observed to increase with increase in the concentration of barium in cobalt tartrate due to the lattice distortion. The band gap and optical properties have analyzed by UV-Visible spectrum. The functional groups and compound formation of the crystals have been studied by FT-IR spectrum. The mechanical properties of the grown crystals were tested by using Vicker’s microhardness studies. The work hardening coefficient (n) was determined to be 3.7 for CTH, 5.3 for BCTH (1 : 1) and 6.4 for BCTH (2 : 1) and the stiffness constants for different loads were calculated and reported. Thermal analysis suggests that pure cobalt tartrate starts decomposing at 73.2 C whereas the barium mixed cobalt tartrate brings about better thermal stability which increases with an increase in barium concentration

Signature Searching Concerning Association Assortment of Files

Signature is the example that you search for inside an information parcel. A signature is utilized to recognize one or numerous sorts of assaults. Signatures may be available in distinctive parts of an information parcel contingent on the way of the assault. We can discover signatures in the IP header, transport layer header (TCP or UDP header) and application layer header or payload. Generally IDS relies on signatures to get some answers concerning gatecrasher movement. With the expanded measure of information exchanged by PC systems, the amoun t of the malevolent movement likewise increments and thusly it is important to ensure the system by security framework, for example, firewalls and the Intrusion Detection System. Example coordinating is the time discriminating operation of current Intrusion Detection System. In this venture this example coordinating is in view of the standard expression where as these example of known   Assaults are put away in the database of Intrusion Detection System. Customary Expressions are regularly used to portray malignant system design

Susceptibility of south Indian strains of Mycobacterium tuberculosis to tuberactinomycin

A total of 114 strains of Mycobacterium tuberculosis isolated from sputum samples of 114 patients of pulmonary tuberculosis in south India, were coded and tested for their in vitro susceptibility to tuberactinomycin (Tum) incorporated in Lowenstein-Jensen (LJ) medium. Of these strains, 95 (83.3%) and 15 (13.2%) were susceptible to Tum at 25 and 50 mg/l respectively. Only 4 (3.5%) strains were inhibited at 100 mg/l or more. Of the 37 drug sensitive strains, 2 (5.4%) were not susceptible to Tum at 25 mg/l compared to 17 (22.1%) of 77 strains-resistant to one or more of antituberculosis drugs (P <0.02). The drug susceptibility pattern of the strains revealed that there was no significant association of resistance between Tum and streptomycin or rifampicin or ethambutol or ethionamide or isoniazid. However, 15 (53.6%) of 28 kanamycin (K) resistant strains were not susceptible to Tum at 25 mg/l. This cross resistance between Tum and K was further studied in 24 and 15 K sensitive and resistant strains respectively, by correlating their proportion resistance at 16 mg/l and it was found to have a significant positive correlation (r = 0.55; X0.01)

Synonymous Codon Usage Analysis of Thirty Two Mycobacteriophage Genomes

Synonymous codon usage of protein coding genes of thirty two completely sequenced mycobacteriophage genomes was studied using multivariate statistical analysis. One of the major factors influencing codon usage is identified to be compositional bias. Codons ending with either C or G are preferred in highly expressed genes among which C ending codons are highly preferred over G ending codons. A strong negative correlation between effective number of codons (Nc) and GC3s content was also observed, showing that the codon usage was effected by gene nucleotide composition. Translational selection is also identified to play a role in shaping the codon usage operative at the level of translational accuracy. High level of heterogeneity is seen among and between the genomes. Length of genes is also identified to influence the codon usage in 11 out of 32 phage genomes. Mycobacteriophage Cooper is identified to be the highly biased genome with better translation efficiency comparing well with the host specific tRNA genes

Preliminary screening for antibacterial and antimycobacterial activity of actinomycetes from less explored ecosystems

Actinomycetes from less explored ecosystems were screened for antibacterial and antimycobacterial activity. Crude bioactive compounds were produced by growing these strains by shake flask fermentation using soybean meal medium. Culture supernatant and mycelia were extracted with ethyl acetate and methanol, respectively. Antibacterial activity of crude extracts was tested by disc diffusion method against gram positive and gram negative bacteria. Actinomycete strains D10, D5, NEK5, ANS2, M104 and R2 showed prominent activity. Culture filtrates and crude extracts were tested against standard strain Mycobacterium tuberculosis H37Rv and drug sensitive and drug resistant clinical isolates of M. tuberculosis by luciferase reporter phage (LRP) assay. Considerable variation was observed in antimycobacterial activity between actinomycete culture filtrates and solvent extracts. Actinomycete strains viz., D10, D5 (desert), CSA14 (forest), CA33 (alkaline soil), NEK5 (Neem plant), MSU,ANS2, R2 and M104 (marine) screened in the present study were found to be highly potent showing good antibacterial and antimycobacterial activity. Five of them such as A3, CSA1, EE9, ANS5 and R9 were exclusively active against M. tuberculosis. Secretary products of actinomycetes of rare ecosystems are meant to antagonize organisms in their respective environments. These are likely to be novel antimycobacterial compounds as they unknown to human pathogens

Use of cetylpyridinium chloride for the storage of sputum samples and isolation of M. tuberculosis

Of 220 sputum specimens collected from pulmonary tuberculosis patients, 85 were culture positive when the sputum aliquots were stored with cetypyridinium chloride (CPC) and processed on 7th day (CPC method), whereas only 70 were culture positive when the aliquots of the same specimens were stored without CPC and processed by sodium hydroxide (NaOH) method. The difference in the culture positivity was statistically significant. The number of positive, cultures obtained by the CPC method (85) was comparable to that obtained by the NaOH method before storage (95) and the difference was not statistically significant
