This paper aims to examine how the concentration of silicon oxide nanoparticles affects the tribological properties of oil lubricant and the noise response of Detroit engine 92V friction parts. The nanoparticles were synthesized by chemical methods such as sol-gel, hydrothermal, and precipitation processes using metallic powders, silicon salts, and alkoxides. The nanoparticles and the tested part were characterized by scanning electron microscopy (SEM). The coefficient of friction and noise response were measured. The analysis showed that the addition of SiO2 nanoparticles improved the tribological performance of the oil and reduced the wear rate of the engine parts due to the lower coefficient of friction. The optimal concentration of SiO2 nanoparticles was found to be 0.25%, which decreased the noise, wear rate, and coefficient of friction by more than 0.5% of SiO2 nanoparticles.

This paper focusses on the effect of aluminium oxide nanoparticles concentration on tribological properties of lubricant oil and noise response on Detroit engine 92V friction parts. The nanomaterials were produced by sol-gel production, process. The manufactured nanomaterials and the tested part were evaluated by scanning electron microscope (SEM) analysis. The coefficient of friction (CoF) and noise response were studied. Results analysis illustrated that the addition of Al 2 O 3 nanoparticles has improved the tribological properties of the lubricating oil and decreases the wear rate of engine parts according to the decrease of CoF. Adding 1% wt. of Al 2 O 3 nanoparticles to oil has decreased the wear rate and the CoF more than 0.5% wt. of Al 2 O 3 nanoparticles addition.

Composites reinforced with natural fibres have been booming in recent years due to their health benefits and environmental friendliness. Today, date palm is particularly attractive in the Middle East region because it is widely available, cheap, and abundant. Date palm has been used in many simple industries since ancient times, for example, in the manufacture of rope. In the present study, date palms were used to reinforce epoxy resin with embedded rubber segments or crushed to use them for industrial applications. First, date palms are chemically treated in three different ways. The fibres are immersed in three different types of chemical solutions (CH3COOH, HCl and alkaline NaOH with three different concentrations of 10%, 20% and 50%) at boiling temperature for 1 and 2 hours. These fibres are then mechanically crushed into small fibre crisps. These fibres are mixed with epoxy resin in which 5% by weight of the rubber segments are embedded. The effects of the chemical treatment of the date palm fibres are analysed using electro-scan microstructure examination (SEM). The tensile test is performed on the standard tensile test specimens of this composite to investigate the effectiveness of the reinforcement by the epoxy resin. The fracture strength and crack propagation are investigated by measuring the surface release energy of the individual composite specimens of date palm fibre reinforced epoxy (DPTFRE). Fracture properties are measured using standard compact tensile specimens at room temperature. A drop-weight impact test was also performed. The maximum and minimum values of tensile strength and crack resistance are …

This study was conducted to evaluate the effect of the some available plant residues as alternative litter materials in New Valley on the growth performance of broiler. The study included six groups of treatments, with three replicates for each treatment (3 replicates of 10 chicks each); (wheat straw, wood sawdust, rice hulls, corn stalks chips, chopped palm fiber and palm spines chips litters). Results of growth performance at final periods or at market age, shows significant differences (P≤0.05) was recorded among different litter types. In that broiler reared on wheat straw, corn stalks chips and palm spines chips litters had significant superiority body weight and gain over the broiler reared on wood sawdust, rice hulls and chopped palm fiber. Also, feed conversion of broiler reared on wheat straw, wood sawdust, corn stalks chips and palm spines chips litters had significant superiority values. No significant differences were found in dressed carcass, while, the lowest abdominal fat is observed for broilers raised on wood sawdust, corn stalks chips and chopped palm fiber litters. Broilers raised on wheat straw and wood sawdust had a significantly (P≤0.05) higher bursa percentage than those of birds raised on rice hulls and chopped palm fiber litters. The lowest leg problems score is observed for broilers raised on corn stalks chips litter in comparison with those raised on rice hulls and chopped palm fiber litters. In conclusion, corn stalks chips and palm spines chips can potentially be used as alternative litter materials for managing broilers in New Valley.

Extracting and determining floods affected zones is one of the most crucial stages in floods hazard management to reduce damages caused by floods. Assessing and determining the accuracy of image classification algorithms is essential in producing accurate flood hazard maps. This study put forward the application of Remote Sensing and GIS computer programs to carry out a comparative analysis of three image classification algorithms: neural network, parallelpipe and minimum distance to test which technique best classifies the 2010 during-flood TerraSAR-X image of Perlis, Malaysia. Confusion matrix was calculated to assess the accuracy of each algorithm.The best result of the flood extent extraction model is from the network algorithm classification with an overall accuracy of 99.7661% and a kappa coefficient of 0.9862. These findings could be used to assist the Government to design appropriate measures to safeguard the lives and properties of the residents of Perlis.

Light composite materials based on Magnesium matrix reinforced with carbon or ceramic nanofibers were fabricated by powder metallurgy rout using high frequency induction heat sintering (HFIHS) technique. A comprehensive comparative study has been investigated on using ceramic nanofibers and carbon nanofibers as a fibers reinforced Magnesium metal matrix in order to evaluate the overall improvements in mechanical properties. Electrospinning technique followed by calcination process were used efficaciously to synthesize and fabricate the Titanium Oxide (TiO2) fibers and carbon fibers. Mg/nanofibers mixtures were prepared via powder metallurgy route using mechanical alloying technique by adding 1, 3, 5 and 10 wt% calcined nanofibers to Mg matrix. In inert atmosphere and room temperature, mixtures were initially processed using high energy ball milling for 15 + 15 min. The final bulk cylindrical …

This paper first describes a slow catalytic pyrolysis process used for synthesizing biodiesel from waste cooking oil (WCO) as a feedstock. The influence of variations in the catalyst type (sodium hydroxide and potassium hydroxide), and catalyst concentration (0.5, 1.0, 3.0, 5.0, 7.0 and 10.0% by weight) on both the pyrolysis temperature range and biodiesel yield were investigated. The results suggested that sodium hydroxide (NaOH) was more effective than potassium hydroxide (KOH) as catalysts and that the highest yield (around 70 wt.%) was observed for a NaOH concentration of about 1 wt.% The resultant pyrolysis temperature range was also significantly lower for NaOH catalyst, thus suggesting overall lower energy consumption. Compared to conventional diesel, the synthesized biodiesel exhibited relatively similar physical properties and calorific value. The biodiesel was subsequently blended with diesel fuel in different blend ratios of 0, 20, 40, 60, 80 and 100% by volume of biodiesel and were later tested in a compression ignition engine. Brake thermal efficiency and specific fuel consumption were observed to be worse with biodiesel fuel blends particularly at higher engine load above 50%. However, NOx emission generally decreased with increasing blend ratio across all engine load, with greater reduction observed at higher engine load. Similar observation can also be concluded for CO emission. In contrast, lower hydrocarbon (HC) emission from the biodiesel fuel blends was only observed for blend ratios no higher than 40%. Particulate emission from the biodiesel fuel blends did not pose an issue given its comparable smoke opacity …
