The increasing demand for natural river sand supply for the use in construction industry along with the issue of environmental problem posed by the dumping of cockle shell, a by-product from cockle business have initiated research towards producing a more environmental friendly concrete. This research explores the potential use of cockle shell as partial sand replacement in concrete production. Cockle shell used in this experimental work were crushed to smaller size almost similar to sand before mixed in concrete. A total of six concrete mixtures were prepared with varying the percentages of cockle shell viz. 0%, 5%, 10%, 15%, 20% and 25%. All the specimens were subjected to continuous water curing. The compressive strength test was conducted at 28 days in accordance to BS EN 12390. Finding shows that integration of suitable content of crushed cockle shell of 10% as partial sand replacement able to enhance the compressive strength of concrete. Adopting crushed cockle shell as partial sand replacement in concrete would reduce natural river sand consumption as well as reducing the amount of cockle shell disposed as waste.]]>

Heart rate variability (HRV) is a measure of the balance between sympathetic mediators of heart rate that is the effect of epinephrine and norepinephrine released from sympathetic nerve fibres acting on the sino-atrial and atrio-ventricular nodes which increase the rate of cardiac contraction and facilitate conduction at the atrio-ventricular node and parasympathetic mediators of heart rate that is the influence of acetylcholine released by the parasympathetic nerve fibres acting on the sino-atrial and atrio-ventricular nodes leading to a decrease in the heart rate and a slowing of conduction at the atrio-ventricular node. Sympathetic mediators appear to exert their influence over longer time periods and are reflected in the low frequency power(LFP) of the HRV spectrum (between 0.04Hz and 0.15 Hz).Vagal mediators exert their influence more quickly on the heart and principally affect the high frequency power (HFP) of the HRV spectrum (between 0.15Hz and 0.4 Hz). Thus at any point in time the LFP:HFP ratio is a proxy for the sympatho- vagal balance. Thus HRV is a valuable tool to investigate the sympathetic and parasympathetic function of the autonomic nervous system. Study of HRV enhance our understanding of physiological phenomenon, the actions of medications and disease mechanisms but large scale prospective studies are needed to determine the sensitivity, specificity and predictive values of heart rate variability regarding death or morbidity in cardiac and non-cardiac patients.

A two-phase model is proposed for describing the dynamics of a fluidized bed reactor used for polypropylene production. In the proposed model, the fluidized bed is divided into an emulsion and bubble phase where the flow of gas is considered to be plug flow through the bubbles and perfectly mixed through the emulsion phase.

In this work the contribution of reaction in the bubble phase is considered and its effect on the overall polypropylene production is investigated the kinetic model is combined with hydrodynamic model in order to develop a comprehensive model for gas-phase propylene copolymerization reactor. Simulation profiles of the proposed model were compared with those of well mixed model for the emulsion phase temperature.

Several software engineering frameworks and methodologies have been developed to provide solutions for deploying cloud computing resources on mobile application development. Agile methodology is one of the most commonly used methodologies in the field. This paper presents the MCCAS a Web and Mobile application that provide feature for the Palestinian higher education/academic institutions. An Agile methodology was used in the development of the MCCAS but in parallel with emphasis on Cloud computing resources deployment.

Firstly, the kinetic equation of spatial cylindrical cam with flexible rod has been established. Then, an accurate cylindrical cam mechanism model has been established based on the spatial modeling software Solidworks. The dynamic effect of flexible rod on mechanical system was studied in detail based on the mechanical system dynamics analytical software Adams, and Archard wear model is used to predict the wear of the cam. We used Ansys to create finite element model of the cam link, extracted the first five order mode to export into Adams. The simulation results show that the dynamic characteristics of spatial cylindrical cam mechanical system with flexible rod is closed to ideal mechanism. During the cam rotate one cycle, the collision in the linkage with a clearance occurs in some special location, others still keep a continuous contact, and the prediction of wear loss is smaller than rigid body.]]>

However, mobile cloud computing, the migration of information on the cloud is reliable their privacy and security issues. Moreover, mobile cloud computing has limitations in resources such as power energy, processor, Memory and storage. In this paper, we propose a solution to the problem of privacy with saving and reducing resources power energy, processor and Memory. This is done through data encryption in the mobile cloud computing by symmetric algorithm and sent to the private cloud and then the data is encrypted again and sent to the public cloud through Asymmetric algorithm.

Rice stem borer is one of the important pests that attack plants so as to reduce production. One way to control pests is to use organic fertilizers that make the plant stronger and healthier. This study was conducted to determine the effects of organic fertilizers with various doses without the use of pesticides in controlling stem borer, Scirpophaga incertulas. Methods using split-split plot design which consists of two levels of the whole plot factor (solid and liquid organic fertilizers), two levels of the subplot factor (conventional and industry, Tiens and Mitraflora), and four levels of the sub-subplot factor of conventional and industry (5, 10, 15, 20 tonnes/ha), and one level of the sub-subplot factor of Tiens and Mitraflora (each 2 ml/l). Based on the results Statistical analysis there were no significant differences among treatments and this shows that the use of organic fertilizers that only a dose of 5 tonnes/ha is sufficient available nutrients that make plants more robust and resistant to control stem borer, besides that can reduce production costs and friendly to the environment when compared with using inorganic fertilizers. ]]>

A novel high-precision curvature-compensated bandgap reference (BGR) without using op-amp is presented in this paper. It is based on second-order curvature correction principle, which is a weighted sum of two voltage curves which have opposite curvature characteristic. One voltage curve is achieved by first-order curvature-compensated bandgap reference (FCBGR) without using op-amp and the other found by using W function is achieved by utilizing a positive temperature coefficient (TC) exponential current and a linear negative TC current to flow a linear resistor. The exponential current is gained by using anegative TC voltage to control a MOSFET in sub-threshold region. In the temperature ranging from -40℃ to 125℃, experimental results implemented with SMIC 0.18μm CMOS process demonstrate that the presented BGR can achieve a TC as low as 2.2 ppm/℃ and power-supply rejection ratio(PSRR)is -69 dB without any filtering capacitor at 2.0 V. While the range of the supply voltage is from 1.7 to 3.0 V, the output voltage line regulation is about1 mV/ V and the maximum TC is 3.4 ppm/℃.]]>

Here we have considered the three different nanotubes including zinc oxide nanotube (ZnONT), silicon carbide nanotube (SiCNT) and single walled carbon nanotube (SWCNT). Three different chiralities such as zigzag (9,0), armchair (5,5) and chiral (6,4) having approximately same diameter are analyzed. The adsorption binding energy values under various cases are estimated with density functional theory (DFT). We observed CO2 molecule chemisorbed on ZnONT and SiCNT’s whereas the physisorption is predominant in CNT. To investigate the structural aspect, the tubes with defects are studied and compared with defect free tubes. We have also analyzed the electrical properties of tubes from HOMO, LUMO energies. Our results reveal the defected structure enhance the CO2 capture and is predicted to be a potential candidate for environmental applications.]]>
