Relaxation and Compressive Characteristic in Composite Glass Fiber reinforced Pipes[ ]


Pipes made from glass fiber reinforced polymer (GRP) have a competitive role in the petroleum industry. The need for evaluating the mechanical behavior of (GRP) pipes is an essential object. Compression and stress relaxation tests are preformed to obtain the main effective mechanical properties of petroleum pips. Experimental results showed that stress relaxation illustrates how polymers relieve stress under constant strain. Static relaxation test is carried out at room temperature. The material shows a poor static relaxation strength with two loading cycles which have been observed for the tested specimen. However, the compressive strength measured in radial direction of curved wall of composite is better than that measure through hoop direction.

Estimation of Air Quality Status due to Quarrying activities and its Impacts on the Environment and Health of the People[ ]


A survey of air quality in an environment informs the safety status or the degree of pollution as indicated by surveillance due to prevalent activities in such area. Results revealed that suspended particulate matter smaller than 10µm in aerodynamic diameter (PM10) values was above acceptable values for ambient air conditions in an area is hazardous to the health of people and the environment. At Umuoghara and environs, dust pollution is a major consideration consequent upon Quarry activities. Exposure to these particles may link to increased hospital admissions.

ROLE OF CURRICULUM FOR THE PROTECTION OF ENVIRONMENT IN PAKISTAN[ ]


The aim of the study is to investigate that the present curriculum has to support the protection of environment in our educational system. Pakistan is an agricultural country. Therefore Pakistan educational system needs education for the environment. But the existing material in curriculum is so limited regarding the condition of environment in Pakistan. The goal of this study is to develop awareness about the environment issues and problems, and try to find out their solution by effective planning of environmental education. Specifically the study was conducted to provide information and knowledge of environment at the secondary level in Pakistan. Knowledge of the person is more impartment factors that effected for obtain place of aware of environment protection. In this research determine curriculum of secondary level of has full fill the knowledge about the protection of environment. In this research, a case study approach was used and data was gathered with the help of survey method. In this research students were surveyed 462 of 9th and 10th classes students of 20 School in city center, towns and village of Khanewal. The results of the study showed that environmental factors are affecting the students, environmental knowledge. Government should include a separate subject of “Environmental Education” (EE) in the curriculum at the secondary level. In this curriculum burning issues as natural environment, basis of life, source of energy, pollution of environment to the existing aspects developed through the separate subject of “Environmental Education” (EE) at secondary level in school.

Electrochemical investigation of duplex stainless steel at carbon paste electrode and its application to the detection of dopamine, ascorbic and uric acid[ ]


Nano-structured duplex stainless steel powders were synthesized by planetary milling of elemental Fe, Cr and Ni powders in dual-drive planetary mill for 10h. The prepared duplex stainless steel powders were characterized by X-ray diffraction, Scanning electron microscope, High resolution transmission microscope, BET surface area measurement. The electrochemical property of prepared duplex stainless steel powder was investigated by cyclic voltammetry. Nano structured duplex stainless steel modified carbon paste electrode shows an excellent sensitivity towards the oxidation of dopamine, ascorbic acid and uric acid in 0.2M phosphate buffer at 7.2 pH. Electrocatalytic property of analyte was investigated at 2, 4, 6 and 8mg concentrations of modifier. The 4mg duplex modified carbon paste electrode show maximum anodic peak current of 25.61µA and hence it is used as modifier to study the electrochemical properties of dopamine, ascorbic acid and uric acid. The fabricated electrode exhibits fast, stable sensitivity, reliable and resistant to material fouling.

QUANTUM COMPUTING – THE EMERGING TECHNOLOGY[ ]


Solving complex problems in the quickest way possible is the most prominent feature required in today’s era. Classical computers still take time to solve real complex problems. Thus, Quantum computers are being developed to solve complex problems using least amount of time. Currently, there exist some algorithms utilizing the advantage of quantum computers. For instance, Shor’s[1] algorithm performs factoring of a large integer in polynomial time, whereas classical factoring algorithms can only do it in exponential time. However, the prospective that quantum computing offers is enticing stupendous interest from both the government and the private sectors. Military applications include the propensity to break encryption keys via brute force searches, while civilian applications range from DNA modeling to complex material science analysis. In this review, we present the important features of quantum computing such as superposition and entanglement with the obstacles this technology faces and the benefits it contains.

Effects of chemical reaction, Soret and Dufour number on unsteady MHD mixed convection flow in the forward stagnation region of a rotating sphere in a porous medium[ ]


Soret and Dufour effects on unsteady MHD heat and mass transfer of a chemically reacting, heat absorbing/ generating fluid in the forward stagnation region of a rotating sphere in a porous medium are investigated. The governing non linear partial differential equations are transformed into non dimensional non linear ordinary differential equations using a similarity transformation and are solved numerically by using MATLAB’s built in solver bvp4c. Comparisons with previously published work are performed and found to be in excellent agreement. Graphical results are presented to show the influence of the Dufour number, Soret number, porosity parameter, order of the chemical reaction, heat source parameter and dimensionless chemical reaction parameter. It is concluded that the Soret number, Dufour number, porosity parameter and the order of the chemical reaction play a crucial role on the heat and mass transfer.

Enhancing virtual switching system of on-chip networks[ ]


The huge datacenters in the world - used in the social networks, researching and computing centers, and storage devices - have faced fundamental problem reflected in the need for high throughput to switch between the large numbers of virtual machines installed in these datacenters. The increased use of cloud applications will increase the need for greater numbers of virtual machines. In order to meet the requirements of this increase, it must be increased the hardware capabilities in the datacenters, through increasing the number of cores in the servers. Therefore, there is a need to provide network architecture that can connect all of these cores and chips very quickly. Consequently, it is necessary to enhance the virtual switching system to achieve the maximum integration and efficiency between the network segments, and analysis the scheduling and virtual queuing algorithms depending on the decisions from the experiences implemented using high-level source code and hardware description scheme with Xilinx platform.

A Case Study to Reduce the Manufacturing Waste Prior to Improve the Productivity Factors of a Litchi Juice Production Plant by Using Value Stream Map and Six Sigma Scale[ ]


This paper depicts how the Value Stream Mapping (VSM) process was used to eliminate the manufacturing waste in a litchi juice production plant of Y food and beverage industry in Bangladesh. A current VSM of litchi juice production line was constructed. Data for constructing the present VSM was collected through production line visits, interviews of workers and observation of machine’s function at different production stages. Different causes of non value adding (NVD) activities were discovered by Present VSM. Six sigma central concepts were used to evaluate the present view of manufacturing waste. At present state, it was found three sigma productions, lower PCE (10.68%), and long lead time (86728 sec). After the involvement of Pareto principles, 5S, JIT and Kaizen philosophy in the production system, it was evaluated that future state PCE would be improved to 24.45%, and lead time would be reduced to 37912 sec.
