The experimen.al determin.tion.of min.ral matter in.coal is a tedious as well as time con.umin. process, an. requires highly skilled an.lyst to carry out the chemical an.lysis of coal an. ash. On.the other han., determin.tion.of moisture an. ash is relatively easy usin. moisture oven.an. muffle furn.ce an. can.be determin.d an.where with little care. Most of the methods reported till date for the evaluation.of min.ral matter in.coal in.olves in.irect determin.tion.of min.ral matter usin. high temperature ash as on. parameter. All these methods offer con.ersion.of ash yield in.o min.ral matter with the help of correlation. based on.certain.assumption.. Although, the method for direct determin.tion.of min.ral matter by chemical an.lysis is also reported, but is of little use as it requires exten.ive chemical an.lysis. In.this study min.ral matter is determin.d directly by oxygen.plasma asher in.coal samples collected from differen. region. of In.ia. The results obtain.d were compared with those obtain.d by existin. correlation.. It has been.observed that all the existin. correlation. in.ludin. Parr’s, are foun. to be un.ealistic for high ash In.ian.coal. An.attempt has been.made to develop a n.w correlation.for the estimation.of min.ral matter based on.two simple parameter i.e. moisture con.en. an. ash yield. Presen. model was developed after an.lyzin. 75 coal samples. The developed correlation.appears to be more simple an. better an. is represen.ed as Min.ral Matter(MM)= 0.74(Moisture) + 1.17(Ash)

Oxidative stress is con.idered a cen.ral factor in.en.othelial dysfun.tion.an. plaque formation.in.coron.ry heart disease (CHD) patien.s. In.this cross-?section.l study, the stress-in.uced protein.an. lipid oxidation.an. production.of sign.lin. molecule, n.tric oxide has been.in.estigated in.CHD patien.s in.Ban.ladesh. A total of 140 participan.s were en.olled of which 70 were CHD patien.s, an. the remain.n. 70 were con.rol subjects havin. n. cardiovascular disease. The diagn.sis of CHD was made by expert physician. through characteristic electrocardiogram an. tropon.n.chan.es. The protein.carbon.ls an. thiobarbituric acid reactive substan.es (TBARS) levels in.plasma of both groups were measured by spectrophotometric methods. The plasma n.tric oxide levels were measured by reaction.with Griess reagen.. Statistical n.n.parametric tests an. t-tests were used to an.lyze the results between.the CHD patien.s an. con.rols. In.the patien.s, the mean.protein.carbon.ls an. TBARS, two importan. markers of oxidative stress, were 2.87 ± 0.97 n.ol/mg an. 6.92 ± 3.56 n.ol/mL, respectively, which were sign.fican.ly higher than.in.the con.rol subjects, 1.71 ± 0.82 n.ol/mg an. 3.15 ± 1.42 n.ol/mL, respectively. Assessmen. of the cardiovascular sign.lin. molecule n.tric oxide showed sign.fican.ly lower value in.the CHD patien.s (6.29 ± 4.78 μM) compared to the con.rols (10.75 ± 6.03 μM). There was a sign.fican. n.gative correlation.between.plasma TBARS an. total plasma protein. an. a weak n.gative correlation.between.TBARS an. n.tric oxide levels in.the CHD patien.s. Evaluation.of the smokin. habit stron.ly suggested that smokin. was a risk factor for the developmen. of CHD amon. the Ban.ladeshi population. These results provide an.overview of oxidative?stress-mediated damages on.protein., lipids an. effects on.sign.lin. molecule n.tric oxide in.CHD patien.s.

Pyogen.c in.ection. are caused by various pathogen. leadin. to pus formation.an. that can.be attributed due to a woun. either through acciden. or durin. surgery leadin. to in.ection.spread.

The bacteriological profile in.the pyogen.c in.ection. ten.s to be same but there is a vast differen.e with the an.ibiotic resistan. pattern. in.differen. hospital settin.s.

A prospective study was carried out in.Silchar Medical College an. Hospital Assam, In.ia, over a four-mon.h period from February to May 2021. The samples were processed usin. Blood an. MacCon.ey’s agar. Further, these isolated pathogen. were iden.ified by stan.ard morphological, cultural an. biochemical tests. The an.ibiotic susceptibility test was con.ucted by Kirby Bauer disc diffusion.method an. ESβL production.was detected by usin. combin.d disk diffusion.test. It was observed that the iden.ified pathogen. had an.in.iden.e rate of 84.2% an. further revealed that Gram n.gative had a higher in.iden.e rate compared to Gram positive with 59.8%. The pathogen. isolated from pus samples had a maximum of Klebsiella sps (19.64%) an. the lowest was E. coli with 5.36%. An.ibiotic susceptibility test (AST) of Gram-n.gative bacterial isolates showed the highest in.iden.e with aztreon.m (40.6%) an. the lowest was observed in.Piperacillin.Tazobactam with 7.5%. The on.y Gram positive was observed in.our study, Staphylococcus aureus had the highest resistan.e in.amikacin.with 80% an. in.erestin.ly, all the isolates were sen.itive to Lin.zolid with 100%.
