Published: October 2014

A method to detect fertilizer concentration of grape tree using chitosan film sensors (CFS) with 1.75% w/v has been developed. Electrochemical deposition has been chosen as an efficient technique for the fabrication of CFS. CFS has been used to detect different concentration of fertilizer ranging from 0 ppm until 60 ppm. The types of fertilizers used in this testing were magnesium sulphate and ammonium molybdate. The electrical laboratory testing result of the CFS shows the de-ionised water (DIW) has the highest response with the value ~81%. The highest response values of CFS of magnesium sulphate and ammonium molybdate content of 10 ppm concentration were ~52% and ~35% respectively. The lowest response values of CFS of magnesium sulphate and ammonium molybdate content of 60 ppm concentration were ~13.5% and ~16% respectively. The results have been proven that CFS can differentiate concentration of fertilizers. The morphological surfaces of CFS were observed with SEM and FTIR. SEM image of CFS showed the film surface was compact and the chitosan was well distributed. FTIR result shows there were N-H and OH groups in chitosan film where they were the main components to sense the fertilizer concentrations. The CFS can fulfil all the reliable sensing properties which include excellent sensitivity, recovery, response time, stability, repeatability and selectivity.

Published: October 2014

Low density polyethylene (LDPE) and natural rubber (NR) filled silica composites were prepared by using internal mixer (Brabender) at 150°C and 50 rpm for 10 minutes. Silica was incorporated into polymer matrix by three mixing routes by using Brabender. In mixing I, filler was added into LDPE/NR blend. In mixing II, filler was added prior to LDPE, which was further compounded with NR. In mixing III, filled was pre-dispersed into NR using two-roll mill, after that the compound is blended with LDPE. The effects of filler incorporation routes on the morphological and tensile properties of prepared composites were studied. Observation from SEM result showed that silica tended to localize in NR phase than LDPE phase in the composite. In addition, silica filled LDPE/NR composite exhibited the highest tensile strength in mixing II and lowest in mixing III. Tensile fracture surface of the composites showed typical morphology of LDPE and NR phase depending on mixing methods. KEYWORDS: LDPE/NR, silica, mixing order, tensile properties, morphology

Authors: Maizana Dina , Bt Ismail Emi Zurima , Hussin Nuriziani
Published: October 2014

This paper describes the harmonic current effect at T-joint and corner joint on 3 phase 100kVA transformer model. The methodology that used to measure a harmonic current is using search coil connected to oscilloscope. The experiment is conducted by changing input voltage with different flux density. From the results obtained, the 3rd order harmonic current shows the highest for both T – joint and corner joint. The highest harmonic occurred at T – joint. For in plane, the harmonic current is 0.237A at corner joint and 0.389A at T - joint. At normal condition, the harmonic current were 0.250A and 0.769A at corner joint and T – joint respectively. This happened because of more energy required for transferring the flux to the left and right of the core. The corner joint of harmonic is less since the flux direction is 90° thus smaller amount of energy is required for the movement.

Modifications in Water Sorption Isotherms of Cement Mortars Caused by Carbonation: Effects of Cycles
Authors: Pham Son Tung
Published: October 2014

This work aimed to examine the influence of carbonation on the water sorption isotherms of cement materials. Two types of normalized CEM I and CEM II Portland cement mortars were carbonated at 20°C, 65% relative humidity and 20% of CO2concentration for 32 days. The pore size distributions determined from the water sorption showed a reduction in microporosity and a slight increase in the mesoporosity. The pores clogging due to formation of calcium carbonate was highlighted by the reduction of the quantity of adsorbed water and the decrease in the hysteresis isotherms. We also studied the coupling effect between carbonation and humidification-drying cycles. The results of this study also indicated that the humidification-drying cycles coincide only from the second cycle because of a difficult evacuation of water during desorption, even at low humidity.
Acid Fracture Conductivity Behavior of Tahe Carbonate: High Closure Stress, Long-Term Conductivity, and Composite Conductivity
Authors: Mou Jia Nye , Yao Mao Tang , Zheng Ke Xiang
Published: October 2014

Acid fracture conductivity is a key parameter in acid fracturing designs and production performance prediction. It depends on the fracture surface etching pattern, rock mechanical properties, and closure stress. The fracture surfaces undergo creep deformation under closure stress during production. Preservation of fracture conductivity becomes a challenge at elevated closure stress. In this paper, we investigated acid fracture conductivity behavior of Tahe deep carbonate reservoir with high closure stress and high temperature. A series of acid fracture conductivity experiment was conducted in a laboratory facility designed to perform acid fracture conductivity. Gelled acid and cross linked acid with different acid-rock contact times were tested for analyzing the effect of acid type and acid-rock contact time on the resulting conductivity. Closure stress up to 100MPa was tested to verify the feasibility of acid fracturing for elevated closure stress. Long-term conductivity up to 7-day was tested to determine the capability of conductivity retaining after creep deformation. Composite conductivity of acid fracture with prop pant was also carried out. The study shows that the fracture retained enough conductivity even under effective closure stress of 70MPa. The gelled acid has a much higher conductivity than the cross linked acid for the same contact time. For the gelled acid, contact time above 60-minute does not lead to conductivity increase. Acid fracture with prop pant has a lower conductivity at low closure stress and a higher conductivity at high closure stress than the acid fracture, which shows composite conductivity is a feasible way to raise conductivity at high closure stress. The long-term conductivity tests show that the acid fracture conductivity decreases fast within the first 48-hour and then levels off. The conductivity keeps stable after 120-hour. An acid fracture conductivity correlation was also developed for this reservoir.

Published: October 2014

Different spinnerets can be used to generate needleless electrospinning with the potential to scale up the production of nanofibers. However, the electrospinning performance, normally refers to the quality of the as-spun fiber and the production rate, is dramatically different from different spinnerets. This study focuses on the electric field of different spinnerets under the same experimental parameters so as to understand the key factors that affect the electrospinning performance of upward needleless electrospinning. Modeling analysis suggested that the electric field could be further concentrated by optimizing the geometry of spinneret. Experimental investigation on needleless electrospinning from different spinnerets proved that the electrospinning performance was improved greatly with the optimization of the electric field of spinneret. Understanding of the relationship between electric field and spinning performance would benefit the design and development of needleless electrospinning.

This study tests the antimicrobial properties of pineapple leaf fiber. Scanning electron microscopy (SEM), infrared analysis (IR) and other test methods were used to examine the microcosmic morphologies of pineapple leaf fiber. As the pineapple leaf fiber adhesive content reduce fiber antibacterial. Adhesive content 54% of fiber to escherichia coli and staphylococcus aureus antibacterial value is maximum. With further reduce fiber adhesive content, fiber antimicrobial declined obviously. The results indicate that the anaerobic bacteria can’t survive in the inside of pineapple leaf fiber where exist a large specific surface-area, lots of holes and Voids, and much oxygen. Pineapple leaf fiber contains a lot of phenols and their derivatives which are effective natural bacteria resistant materials and inhibit the metabolism and physiology of bacillus and other microorganism,break the structure of germ, and repress the generation of bacillus until the death of germ.Moreover, the existence of a small amount of cannabinol is adequate to kill the microorganisms.
