The aim of this research work was to develop flame retardant gloves and describes the performance requirement as well as the design of specialized fabric to provide protection against thermal/flame hazards.Fabric flammability is affected by various factors such as Fibre composition, fabric construction, oxygen concent…
Natural fibers, such as sisal, flax and jute, possess good reinforcing capability when properly compounded with polymers. These fibers are relatively inexpensive, originate from renewable resources and possess favorable values of specific strength and specific modulus. Thermoplastic polymers have a shorter cycle time…
Diverse pectin rich sources like food dumps, food waste waters, spoiled fruits, vegetables and alkaline soils were screened for alkaline bacterial pectinolytic isolates by enrichment culturing and ruthenium red plate assay. Six different bacterial isolates with higher zones of pectin hydrolysis from the source food wa…
Heat resistant martensitic steel X20CrMoV121 (DIN) is extensively used in the last few decades as a material for tubing systems and pipelines in thermal power plants. Long term behaviour of this material is well known and understood. X20CrMoV121 is found to be reliable for prolonged service at elevated temperatures. M…
compared to other storage materials. However, a vast amount of heat is generated during refueling of hydrogen in HPMH, where the heat will slow down or stop the absorption of hydrogen into the storage tank and causes a slow refueling time. Aside from heat generation, usage of heat exchangers for dissipation of heat in…
Harmful effects of textile industry effluents are a huge problem for now a days. It creats many problems at different level of ecosystem. The textile industry generates a high volume of waste products. Approx. seventy tons of dye is used annually. A big portion of such amount is discharged in a huge amount of water wh…
AISI 316L stainless steel has been widely used for biomedical material implants that needs high corrosion resistance and strength. Some methods have been developed in order to obtain its high performances, such as cold deformation and SMAT. This research aims to study the effects of combined methods (cold deformation…
Cemented tungsten carbide (WC-Co) is an indispensable material used in many manufacturing sectors including metalworking, oil and gas drilling, geothermal energy exploration, mining, construction, high-wear components, and other applications. The wide range of applications of WC-Co is because of its superior combinati…
In this article the possibility of quantum chemical models creating of initial and protonated potassium titanates and the predict of the interaction between polymer matrix and titanates fi ller was investigated in connection with the increasing interest in nanodispersed titanates as polymeric materials fi llers to cre…
The necessary attention given to the selection of base fabric for the protective clothing against heat and fire is, sometimes, neglected when manufacturing the product. Factors such as outsourcing of the sewing process by the companies and the quality inspection only at the end may raise difficulties not only to the s…
In this paper, the optimization control of cavitation spatial distribution by using of dual sound sources in liquid is investigated experimentally. An experimental system for cavitation spatial distribution control is set up and the “point” cavitation measuring method is proposed, which is a necessity in the optimizat…
The electro less plating method use in metal plating on a porous substrate is disclosed. the deposition of metal ion is done by selective contact of the plating metal salt solution with a reducing solution on the activated surface on or inside the porous substrate. Before plating process The process is accomplished by…
The Leader initiation and propagation processes observed in a negative rocket-triggered lightning discharge in southern China were analyzed and discussed. The observations included a broadband VHF lightning interferometer with a slow antenna located at 90 m in south to the rocket launcher and a video camera located at…
3 Abstract: This study investigates the effect of temperature on removal of sub-micron particles from metal surfaces for various frequencies. The frequency used for this study was 25 kHz, 40 kHz, 58 kHz, 58/132 kHz, 132 kHz, 360 kHz, 470 kHz and 1 MHz. The temperature studied ranging from 30 ο C - 70 ο C. The parts ar…
Two novel fluorescent naphthalimide dyes with acetylamino and amino groups were prepared for the first time by imidation, reduction and acetylation reactions from 4-nitro- 1,8-naphthalic anhydride as a starting material. The synthesized dyes were characterized by FTIR, differential scanning calorimetry (DSC), 1 HNMR,…

King Plastic Corporation does not intentionally add any lead…
The effective atomic number and electron density is calculated for some selected Plasticizers like Diethylene glycol dinitrate (DEDGN), Triethylene glycol dinitrate (TEGDN), Butanetriol trinitrate (BTTN), Trimethylolethane trinitrate (TMETN), Diethyl phthalate (DEP) and Diisobutyl phthalate (DIBP) for gamma radiation…
Phase diagrams of the binary systems of Nicotinamid e (NA) with o-Nitroaniline (oNA), Cinnamic acid (CA ) and 2Methylimidazole (MIm) have been studied by thaw mel t method. The result infers that all these mixtures are simple eutectic in nature. Eutectics (E) of NA-oNA, NA-CA and NA-MIm are formed at 65 °C, 100 °C and…
