2Performance of passive and reactive profiled median barriers in traffic noise reduction显示文摘Median noise barriers, like parallel noise barriers, can be employed to reduce the impact of traffic on roadside communities via the direct propagation path. The performance of different shapes of median barriers was compared using reactive and passive surfaces and a 2D boundary element method (BEM). In the case of reactive surfaces, quadratic residue diffusers (QRDs) and primitive root diffusers (PRDs) were used on the top and stem surfaces of median barriers. To introduce passive barriers, two different absorbent materials including fibrous material and a grass surface with flow resistivity of 20 000 and 2500 kg/(s·m2), respectively, were similarly applied. The effect of thin absorptive barriers was similar at lower frequencies and better at mid and high frequencies to that of their equivalent rigid barriers. More improvement was achieved by covering the top surface of thick barriers with grass rather than with fibrous material. The performance of QRD and PRD barriers where the diffuser was located on the top surface was more frequency dependent than that of barriers coated with fibrous material. A comparison of the average A-weighted insertion loss in the thick barriers showed that the greatest improvement (2.59 dB (A)) was achieved using a barrier of 30-cm thickness covered with grass.Mohammad Reza MONAZZAM Samaneh Momen Bellah FARD 2011Journal of Zhejiang University-Science A(Applied Physics & Engineering)2011,12,1:1

15Phytopharmacological evaluation of ethanol extract of Sida cordifolia L.roots显示文摘Objective:To investigate the phytochemical screening(group determination)and selected pharmacological activities(antioxidant,antimicrobial and analgesic activity)of the plant Sida cordifolia Linn(S.cordifolia).Methods:Eighty percent concentrated ethanol extract of the roots was used.To identify the chemical constituents of plant extract standard procedures were followed.In phytochemical screening the crude extract was tested for the presence of different chemical groups like reducing sugar,tannins,saponins,steroids,flavonoids,gums,alkaloids and glycosides.The antioxidant property of ethanolic extract of S.cordifolia was assessed by DPPH free radical scavenging activity.Analgesic activity of the extract was tested using the model of acetic acid induced writhing in mice.Diclofenac sodium is used as reference standard drug for the analgesic activity test Antibacterial activity of plant extract was carried out using disc diffusion method with five pathogenic bacteria comparison with kanamycin as a standard.Results:Phytochemical analysis of the ethanolic extract of the roots of S.cordifolia indicated the presence of reducing sugar,alkaloids,steroids and saponins.In DPPH scavenging assay the IC_(50)value was found to be 50 ug/mL which was not comparable to the standard ascorbic acid.The crude extract produced 44.3%inhibition of writhing at the dose of 300 mg/kg body weight which is statistically significant(P>0.001).The in vitro antimicrobial activity of the ethanol extract of the roots of S.cordifolia showed no antimicrobial activity against five types of microorganisms.The experiment was conducted only with five species of bacteria as test species,which do not at all indicate the total inactivity against micro-organisms.Condusions:The obtained results provide a support for the use of this plant in traditional medicine but further pharmacological studies are required.Mohammad Abdul Motalib Momin Sm Faysal Bellah Sarder Mohammad Raussel Rahman Ahmed Ayedur Rahman Gazi Mohammad Monjur Murshid Sarder Mohammad Saker Billah Talha Bin Emran 2014Asian Pacific Journal of Tropical Biomedicine2014,4,1:1

20High-quality liquid phase-pulsed laser ablation graphene synthesis by flexible graphite exfoliation显示文摘This work reports a one-pot procedure of laser ablation on a graphite target in a liquid medium, based on the variation of different parameters such as target type, laser wavelength, and ablation medium,to obtain high-quality graphene nanosheets. The morphology of derived products was characterized by the field emission scanning electron microscopy(FE-SEM). Then, the morphology and structure of the optimized sample were characterized by transmission electron microscopy(TEM), X-ray diffraction(XRD), ultraviolet-visible-near infrared(UV–vis-NIR) spectroscopy, Raman spectroscopy, and X-ray photoelectron spectroscopy(XPS). By controlling the laser ablation parameters, we were able to prepare micrometer-sized few-layer graphene nanosheets with mainly less than ten layers. Such synthesized graphene nanosheets were grown at the surface of a flexible graphite target, indicating many potential applications in fundamental research, electrochemical and as hydrophobic surfaces.M.Jalili H.Ghanbari S.Moemen Bellah R.Malekfar 2019Journal of Materials Science & Technology2019,35,3:1
