In order to increase the efficiency of the conveyance of the granular solids, a new experimental set-up is designed. The test rig has longitudinal trapezoidal slots in its conveying pipes. Through experimentation, a correlation for friction factor in terms of solid mass flow rate, fluid flow rate and Froude number is presented. It is shown that the mixture friction factor for pipes with inn...

BACKGROUND Concurrent use of tobacco products such as cigarettes and water pipes may be associated with increased risk of nicotine dependence and smoking-related complications. Accurate statistics are not available regarding the prevalence of water pipe use or concurrent use of cigarettes and water pipe in the Iranian population. Thus, this study sought to assess the prevalence of concurrent us...

Kimberlites discovered so far in southern India are restricted to the Eastern Block of the Dharwar Craton and are distributed in three fields: Wajrakarur, Narayanpet, and Raipur. As summarized recently by Paul et al. (2006) and Patel et al. (2006), known kimberlite pipes in the Wajrakarur kimberlite field (WKF), which lies at the western margin of the Cuddapah Basin, occur in three clusters: Wa...

With the objective of contrasting performance between STREAMS and legacy approaches to system facilities, a comparison is made between the tested performance of the Linux legacy pipe implementation and the STREAMS-based pipe implementation using the Linux Fast-STREAMS package [? ]. 1 Background Pipes have a rich history in the UNIX operating system. Present on early Bell Laboratories UNIX Versi...

The effects of vacuum ultraviolet (VUV) treatment on surface chemical composition morphology and albumin adsorption for low-density polyethylene (LDPE) and high-density polyethylene (HDPE) were investigated. The attenuated total reflection-Fourier transform infrared (ATR-FTIR) spectra and contact angle measurements indicated the formation of oxygen-containing polar groups and double bonds under...

This study investigated weathering performance of an HDPE wood plastic composite reinforced with extracted or delignified wood flour (WF). The wood flour was pre-extracted with three different solvents, toluene/ethanol (TE), acetone/water (AW), and hot water (HW), or sodium chlorite/acetic acid. The spectral properties of the composites before and after artificial weathering under accelerated c...

The influences of filler size and content on the properties (thermal conductivity, impact strength and tensile strength) of Al2O3/high density polyethylene (HDPE) composites are studied. Thermal conductivity and tensile strength of the composites increase with the decrease of particle size. The dependence of impact strength on the particle size is more complicated. The SEM micrographs of the fr...

The pyrolysis of waste newspaper (WP) and co-pyrolysis of waste newspaper with high-density polyethylene (HDPE) (1:1 wt%) were carried out in a quartz tube at 500 °C to obtain biochars. The biochars were characterized in detail by X-ray diffraction (XRD), thermogravimetric analysis (TG), Fourier transform infrared spectroscopy (FT-IR), X-ray photoelectron spectroscopy (XPS), elemental analysis,...

The aim of this study is evaluating the interaction between several base pen grade asphalt binders (35/50, 50/70, 70/100, 160/220) and two different recycled plastics (EVA and HDPE), for a set of new polymer modified binders produced with different amounts of both recycled plastics. After analysing the results obtained for the several polymer modified binders evaluated in this study, including ...
