Laser electrospray mass spectrometry (LEMS) is demonstrated for pharmaceutical samples at atmospheric pressure. A nonresonant, femtosecond duration laser pulse vaporizes native samples at atmospheric pressure into an electrospray plume for ionization with subsequent transfer into a time-of-flight mass spectrometer. The active ingredients in pharmaceutical tablets were detected in the presence o...

The main idea of this work is to investigate the effect of knitted fabrics characteristics on moisture management properties. Wetting and transport properties of single jersey, Rib 1&1 and English Rib fabrics made out of cotton and blended Cotton/Polyester yarns were studied. The dynamic water sorption of fabrics was investigated under same isothermal and terrestrial conditions at 20±2°C-65±4% ...

Protective clothing performs a vital role in maintaining the safety of human in workplace. The developments in this field are proceeding to fulfill the needs with multifunctional materials at competitive costs. Recently, the protective clothing field introduces the usage of composite materials taking advantage of their outstanding properties. In this paper, the multifunctional performance of hy...

This article presents an experimental investigation carried out to understand the mechanical behavior of composite materials made of 3D stitched woven-knitted basalt fabrics. The innovative preforms used consist of two outer layers of a plain woven fabric combined with two inner layers of weft-knitted fabrics. The weft-knitted fabrics selected for the study were varied plain knit, 1 × 1 rib, Mi...

In this research work, samples of the biocomposite were manufactured using vacuum assisted resin transfer molding (VARTM) technique, whose matrix is a polyester and reinforcement biaxial fabric (90°) made with jute fiber. Then, tensile flexural tests carried out on standardized specimens under ASTM standards, in order to mechanically characterize jute-polyester biocomposite. both destructive te...

The national planners have put infrastructures development on priority. This has resulted in transport planning widening of National Highway and new roads in country. Thus work of Retaining Earth (RE) structures/ slopes will be going to design in very large numbers over different areas. The availability of backfill material compatible with geosynthetics reinforcements and economy in both has be...

The median effective dose of permethrin for knockdown and mortality of Anopheles farauti s. s. exposed to 2 net and 2 cloth fabrics was estimated. There were no significant differences in the knockdown or mortality of An. farauti or Aedes aegypti following 15-180-sec exposure to permethrin-treated bed nets and polyester/cotton fabric. Despite the presence of permethrin (0.007-0.068 mg/cm2) in b...
