The construction sector is one of the main consumers raw materials and generates a high volume waste within European Union. search for new that are more sustainable respectful environment has become challenge countries with degree industrialization. In this work, study most relevant properties masonry mortars made recycled aggregates reinforced synthetic fibers was carried out. Three types were...

Escherichia coli (E. coli) was used to activate hydrolysis reaction along with biodegradation in natural and synthetic fibers to identify possibilities as alternative substitutes for textile wastes using chemical solutions and enzymes. To confirm the reaction between the bacterial infections of E. coli and the excessively abundant interstitial spaces of the fibers, various types of natural and ...

Inhalation toxicology studies with chrysotile asbestos have in the past been performed at exceedingly high doses without consideration of fiber number or dimensions. As such, the exposures have exceeded lung overload levels, making quantitative assessment of these studies difficult if not impossible. To assess the cellular and pathological response in the rat lung to a well-characterized aeroso...

Abstract Background Various recent studies have investigated the use of traditional fibers (metallic or synthetic) as reinforcement in mortar. In times, there has been growing interest using natural cement composites. This study was conducted to assess impact date palm, doum and sisal on mechanical properties Genetic modeling chosen find shear damage at fiber-matrix interface three composites g...

The use of natural fibers including abaca has increased because its advantages such as lightweight, low price, life-cycle superiority, and substitute for synthetic fibers. This paper gives an insight into the effect three different treatments on fibers: hornification, NaOH 3% concentration solution, a coating silica fume with latex cementitious composites; have been characterized before after t...

Stack and duct analyses have been conducted on textile finishing ranges processing cottrn and synthetic fibers. Analytical methods used include gas chromatography, infrared spectroscopy and gravimetric analysis. Synthetic fiber spin finish, knitting lubricanis and cotton resin finishes were identitied in stack samples. When particulate loading was of interest, isokinetic samples of the stack ga...

Counties in the United States have been identified with chemical establishments whose primary manufacturing processes use vinyl chloride. Site-specific cancer mortality comparisons have revealed an excess of multiple myeloma in males associated with two of the manufacturing categories, synthetic rubber and synthetic fibers. A causal relationship between these manufacturing categories and multip...

UICC, other well-defined asbestos samples and different man-made mineral fibers (MMM) such as glass fiber and synthetic amphibole asbestos were studied in vitro by using rat and guinea pig lung macrophages. These samples had relatively narrow length and diameter spectra. Most of the fiber samples were added to the cultures on a gravimetric basis, although some were added on a numerical basis. E...

Synthetic fibers enter wastewater treatment plants together with natural fibers, which may affect efficiency, a fact not considered in previous studies. Therefore, the aim of present study was to evaluate efficiency coagulation/flocculation process for removal mixture textile from different water matrices. Natural and synthetic (100 mg/L; cotton, polyacrylonitrile, polyamide) were added matrix,...

The aim of this work was to develop a simple and fast 3D MRI-based computer model of arrhythmia inducibility in porcine hearts with chronic infarct scar, and to further validate it using electrophysiology (EP) measures obtained in-vivo. The heart model was built from MRI scans (with voxel size smaller than 1mm) and had fiber directions extracted from diffusion tensor DT-MRI. We used a macroscop...
