The Effects Of Sawdust Addition On The Insulating Characteristics Of Clays From The Federal Capital Territory Of Abuja Abstract: l Capital of Abuja like linear shrinkage, solid density, apparent porosity and thermal conductivity were characterized with a view of studying the effect of sawdust on them. The results showed that the linear shrinkage improved from an average of 8.57% for the three samples for 0% sawdust to an average of 8.32% with 40% addition of saw dust, bringing them closer to the lower range of the international standard of 7-10%. Solid density averaged 3.18g/cm3 with 0% saw dust and 2.91g/cm 3 with 40% saw dust, still bringing them closer to the international range of 2.3-3.5g/cm3.
The value of your 7.65mm (.32 caliber) WWII Walther PP & holster set depends on when it was made (you can tell this from the serial number), who it was captured from, whether it has matching serial numbers, commercial or military inspection stamps, the amount of pitting (hopefully none) and blue remaining, the type. When was my Walther gun made? It's easy to determine if you know where to look and know how the date coding is configured. If you want to know. Be 10 or 2010. A = 0; B = 1; C = 2; D = 3; E = 4; F = 5; G = 6; H = 7; I/J = 8; K = 9. NOTE: The PPK does not use this letter code for manufacturing year.
Apparent porosity averaged 13% with 0% saw dust and 17% with 40% addition of saw dust bringing them closer to the acceptable range of 20-80%. While thermal conductivity averaged 0.493W/mo k with 0% saw dust and 0.134W/mo k with 40% saw dust thereby improving their insulating properties. This 40% sawdust addition was discovered to be the maximum under which mechanical strength and other refractory properties of clay will remain stable.

Synthesis of Silver Nanoparticles from Microbial Source-A Green Synthesis Approach, and Evaluation of its Antimicrobial Activity against Escherichia coli Abstract: Nanoparticles synthesis by biological methods using various microorganisms, plants, and plant extracts and enzymes have attracted a great attention as these are cost effective, nontoxic, eco-friendly and an alternative to physical and chemical methods. In this research, Silver nanoparticles (Ag-NPs) were synthesized from AgNO3 solution by green synthesis process with the assistance of microbial source only. The detailed characterization of the Ag NPs were carried out using UV-visible spectroscopy, Scanning electron microscopy (SEM), Energy dispersive X-ray Spectroscopy (EDS), Dynamic light scattering (DLS) analysis, and their antimicrobial evaluation was done against Escherichia coli.
The UV-visible spectroscopy analysis showed the surface plasmon resonance property of nanoparticles. The DLS analysis showed the particle distribution of synthesized silver nanoparticles in solution, and SEM analysis showed the morphology of nanoparticles. The elemental composition of synthesized sample was confirmed by EDS analysis. Antibacterial assay of synthesized Ag NP was carried out in solid (Nutrient Agar) growth medium against E.coli. The presence of zone of inhibition clearly indicated the antibacterial activity of silver nanoparticles.

Recognition of Similar Shaped Handwritten Marathi Characters Using Artificial Neural Network Abstract: The growing need have handwritten Marathi character recognition in Indian offices such as passport, railways etc has made it vital area of a research. Similar shape characters are more prone to misclassification.
In this paper a novel method is provided to recognize handwritten Marathi characters based on their features extraction and adaptive smoothing technique. Feature selections methods avoid unnecessary patterns in an image whereas adaptive smoothing technique form smooth shape of charecters.Combination of both these approaches leads to the better results. Previous study shows that, no one technique achieves 100% accuracy in handwritten character recognition area. This approach of combining both adaptive smoothing & feature extraction gives better results (approximately 75-100) and expected outcomes.

An Overview Of Pavement Management System For Industrial Areas Abstract: With the current surge in national economy the industrial traffic has increased many folds in terms of quantity of load and traffic volume. This results in early deterioration of the roads.
Also the serviceability reduces hampering the industry's supply of raw material and transport of finished goods. An efficient road transportation system is of vitally important for smooth operations of industrial units. Construction of new roads needs an enormous investment. However, once constructed the road network system requires huge resources to maintain serviceability and to ensure safe passage at an appropriate speed and with low VOC (Vehicle Operating Cost). Road maintenance is therefore an essential function and should be carried out on a timely basis. The cost of providing and maintaining the roads for the industrial areas at an acceptable serviceability level is quite high. It is therefore essential for a transportation engineer to attempt establishing an acceptable pavement condition level from economic, safety and environmental point of view.
In today's economic environment of constrained budgets, as the existing road infrastructure has aged, a more systematic approach towards determining maintenance and rehabilitation needs is necessary. The efficient pavement management system shall provide objective information and useful analysis to ensure consistent and cost effective decisions related to preservation of existing industrial road network in healthy condition.

Effects Of Different Fragmentation Thresholds On Data Dropped And Retransmission Attempts In A Wireless Local Area Network Abstract: act This paper discusses the effects of different fragmentation thresholds on data dropped and retransmission attempts in a wireless local area network. A wireless local area network (LAN) is a network that connects computer systems and devices within the same geographical area but without the use of wire. Fragmentation threshold is one of the parameters used in a wireless local area network which specifies the values to decide if the Media Access Control (MAC) Service Data Unit (MSDU) received from the higher layer network needs fragmentation before transmission.
The number of fragments to be transmitted is calculated based on the size of the MSDU and the fragmentation threshold. OPNET IT guru 9.1 software was used for the analysis. Based on the graphical results obtained, it can be said that fragmentation increases the size of queue and the number of data dropped in a transmission, and also the smaller the fragmentation, the more increase in the retransmission attempts. Key words: Data dropped, fragmentation threshold, LAN, packet drop probability, retransmission attempts. Reference [1] Ralph M. Stair and George W.

Production of Household Paint using Clay Materials Abstract: The use of clay materials for the production of emulsion paints was investigated. Two types of clay: White tinged with Purple and Smooth clay (WSP) and Grey Brown and Coarse clay (GBC), were used for the production of Emulsion Clay Paints (ECP). Conventional Chemical pigmented Paint (CP) was also produced as a control. Atomic Absorption Spectroscopy, (AAS) was used to determine the chemical composition of the clay and the concentration of heavy metals on the paints produced.
Total organic content (TOC) and quality control tests were also carried out on the paints. The results of the analysis on the two clay types showed that they contained (45.26 and 47.370)% of silicon oxide and (38.26 and 35.72)% of aluminum oxide respectively. ECP has TOC values of (0.34-0.52)% while CP has TOC value of (0.29-0.31). The cost per litre of CP was (N262.17) while that of ECP was (N111.64), which is about 50% lesser.

Detecting Copy Move Forgery In Digital Images Abstract: In today's world several image manipulation software's are available.
Manipulation of digital images has become a serious problem nowadays. There are many areas like medical imaging, digital forensics, journalism, scientific publications, etc, where image forgery can be done very easily. To determine whether a digital image is original or doctored is a big challenge. To find the marks of tampering in a digital image is a challenging task. The detection methods can be very useful in image forensics which can be used as a proof for the authenticity of a digital image. In this paper we propose the method to detect region duplication forgery by dividing the image into overlapping block and then perform searching to find out the duplicated region in the image. Key words: — Image forgery, Copy move forgery, Block matching, PCA, Region duplication detection.

This effect of Cross-core interference is a major performance bottleneck. It is important that Chip multiprocessors (CMPs) incorporate methods that minimise this interference. To do so, some accurate measure of Cross Core Interference needs to be devised. This paper studies the relation between Instructions per cycle (IPC) of a core and the cache miss rate across various workloads of the SPECCPU 2006 benchmark suite by conducting experimentation on a Full System simulator and makes some important observations that need to be taken into account while allocating resources to a core in multi-core processors.

This mechanism is also known as Ajax: Asynchronous JavaScript and XML. The intent of Ajax is to exchange small pieces of data between the browser and the application server, and in doing so, use partial page refresh instead of reloading the entire Web page. AJAX (Asynchronous JavaScript and XML) is a powerful Web development model for browser-based Web applications. Technologies that form the AJAX model, such as XML, JavaScript, HTTP, and XHTML, are individually widely used and well known. However, AJAX combines these technologies to let Web pages retrieve small amounts of data from the server without having to reload the entire page.
This capability makes Web pages more interactive and lets them behave like local applications. Web 2.0 enabled by the Ajax architecture has given rise to a new level of user interactivity through web browsers. Many new and extremely popular Web applications have been introduced such as Google Maps, Google Docs, Flickr, and so on. Ajax Toolkits such as Dojo allow web developers to build Web 2.0 applications quickly and with little effort.

A Review Of Failure Of Composite Materials Abstract: Composite materials are ideal for aerospace applications due to their high strength to weight ratio and their excellent fatigue resistance. Fiber reinforced Composite is widely used in light weight structures for different applications. The main properties that describe a composite material are the engineering constants and the strength properties of a single unidirectional lamina that make the laminated structure. The experimental evaluation of these properties is quite costly and time consuming because they are functions of several variables such as the individual constituents of the composite, fiber volume fraction, packing geometry and fabrication processes.
Hence, analytical models to predict these properties were developed by researchers to aid the design of composites. In recent years numerous failure theories have been proposed and are available to the composite structural designer. Object of this review is to gather the available guide lines for theoretical models of failure analysis of fiber reinforced Composite. Reference [1]. Daniel and O.

Two different MatLab based programmes were developed; one program was for Load Flow Studies which determines prefault conditions for the power system based on Newton-Raphson method. The other program determines fault current magnitudes for threephase short-circuit on the power system.
The information gained from the fault studies can be used for proper relay select Key words: Power System, Power Flow, ThreePhase Fault, Short-Circuit Current. Reference [1] Muhammad, Aree A.

JIT: A Strategic Tool of Inventory Management Abstract: Investment in inventory absorbs a large portion of the working capital of a company and often it represents a large portion of the total assets of a business. By improving return on investment by increasing the rate of inventory turnover, management often wants to ensure economic efficiency. Effective inventory management enables a firm to provide lower costs, rapid response and flexibility for its customers. Just-in-time (JIT) philosophy is most widely adopted and practices in the recent years worldwide.
It aims at reducing total production costs by producing only what is immediately needed and eliminates wastes. It is based on a radically different concept, deviating substantially from the existing manufacturing practices in many respects. It is a very effective tool to reduce the wastage of inventory and manage it effectively. It has the potential to bring substantial changes in the existing setup of a company; can give it a new face, broaden its acceptability and ensure a longer life. It can strategically change the atmosphere needed for longer survival. JIT is radically different from MRP and goes beyond materials management. The new outlook acquired by the company can meet global expectations of the customers.
JIT happens to provide global markets. The present paper examines the strategic role of JIT in inventory management. Information technology helps JIT in managing inventory effectively, as it helps in integrating the components of supply chain network. Quality aspect of inventory management has also been discussed. Key words: Inventory, Inventory management, ABC Analysis, JIT, Information system, Quality, Supply chain network, SCM.

Effect of Wafer Dimension on the Dispersion and other Polarizing Abstract: In this paper we propose some index guided Photonic Crystal Fiber (PCF) with elliptical holes. The design has been proposed such that it shows a decrease in the value of ratio of the area of elliptical air holes to that of the wafer dimension. The effect of variation in wafer dimension of a constant lattice size is analyzed for observing the unique properties of PCF like dispersion, birefringence, confinement loss and other polarizing properties. The simulation of the proposed structures has been carried out using OptiFDTD simulator with Full vector mode solver using FDTD method. The dispersion reported is almost zero at a wavelength of 0.3m for some of the structures proposed.
It is observed that all the structures proposed has shown the most negative dispersion in between the wavelength range of 0.35 0.4 m m . The birefringence reported is of the order of 103. However the confinement loss reported is low and of the order of 105. Besides zero confinement loss is observed at a wavelength of 0.25m and at 0.9m for the structure proposed in configuration V and configuration I.

Lean manufacturing: A better way for enhancement in productivity Abstract: Productivity is the impact of peoples working together. Machines are merely an extended way of collective imagination and energy. Lean Manufacturing is the most used method for continues improvement of business. Organization management philosophy focusing on the reduction of wastage to improve overall customer value.
'Lean' operating principles began in manufacturing environments and are known by a variety of synonyms; Lean Manufacturing, Lean Production, Toyota Production System, etc. It is commonly believed that Lean started in Japan 'The notable activities in keeping the price of Ford products low is the steady restriction of the production cycle. The longer an article is in the process of manufacture and the more it is moved about, the greater is its ultimate cost.' 'A systematic approach to identifying and eliminating waste through continuous improvement, flowing the product at the pull of the customer in pursuit of perfection.'
Keep in mind that Lean applies to the entire organization. Although individual components or building blocks of Lean may be tactical and narrowly focused, we can only achieve maximum effectiveness by using them together and applying them cross-functionally through the system. Reference [1].

Synthesis, Characterization and Alignment of Mn2+ and/or Eu3+ Doped Cadmium Telluride Nanowires Abstract: The foremost objective of the proposed research is to synthesize magnetically-active CdTe nanowires that can be manipulated by magnetic fields.
The ability to do so will facilitate fabrication of molecular electronics and a whole host of other potential applications. The research will employ doping of CdTe with either Mn2+ or Eu3+ or a mixture of both to create nanoparticles with net magnetic moments. The particles size and morphology will be probed by AFM and TEM while the extent of doping and distribution of dopant ions will be determined by bulk analysis by ICP, surface analysis by XPS, EPR and X-ray powder diffraction. The magnetic moment and magnetic ordering will be determined by use of a SQUID magnetometer. Doped CdTe particles with suitable magnetic moments will then be converted to CdTe wires using a technique originally developed for undoped CdTe.
The changes in morphology, size, composition, and structure will be monitored using the same analytical methods used for characterization of the precursor nanoparticles. Finally, nanowires that possess a sufficient magnetic moment will be aligned using a magnetic field to prove the viability of this approach for manufacturing nanoscale devices and electronics.

Use of Experimental Box-Behnken Design for the Estimation of Interactions Between Harmonic Currents Produced by Single Phase Loads Abstract: In this paper, it is aimed to deal with the interactions of harmonic currents produced by different single phase loads. For this purpose, compact fluorescent lamps, incandescent lamps, and electric heaters were chosen as single phase loads. The study was performed by adopting a full range of response surface methodology using Box–Behnken experimental design to express the net harmonic current (3rd and 5th) as an empirical model. The model provided an excellent explanation of the relationship among the number of loads and the net harmonic currents.
Contour graphs of some of the harmonic currents was plotted to show the interactions clearly and to discuss the results of model in the graphic detail. The results of experiments showed that the harmonic interaction between the loads can be defined as a regression model which is statistically significant.

Finger Vein &Texture Recognization Using Score Level Fusion And 2-D Gabor Filter For Human Identification Abstract: The paper presents a new approach to improve the performance of finger-vein identification systems presented in the literature.
The proposed system simultaneously acquires the finger-vein and low-resolution fingerprint images and combines these two evidences using a novel score-level combination strategy. We examine the previously proposed finger-vein identification approaches and develop a new approach that illustrates it superiority over prior published efforts. We develop and investigate two new scorelevel combinations, i.e., holistic and nonlinear fusion, and comparatively evaluate them with more popular score-level fusion approaches to ascertain their effectiveness in the proposed system.

Comparison of Interestingness Measures: Support-Confidence Framework versus Lift-Irule Framework Abstract: Data Mining is considered to be a step of paramount importance in the process of Knowledge Discovery in Databases. The term 'Interestingness Measure' unequivocally forms a very essential aspect of extraction of 'interesting' rules from databases. As there are a huge number of association rules or patterns that are generated by most Association Rule Mining Algorithms, there arises a need to prune away the unnecessary and unwanted rules. The rules that are crucial and indispensable can therefore be presented to the end user based on the application of these 'Interestingness Measures'.
The reason this is done is so that the user gets a narrow focus on only those rules that will provide better business understanding and intelligence. However, there are a plethora of measures available today, and selecting the best amongst them requires a thorough research on each of them. This paper therefore provides a comparative study of certain important measures, thereby highlighting which measure is apt for application in which situation.

Optimal Selectionof Binary Codes for Pulse Compression in Surveillance Radar Abstract: The papers aim to make a comparative study of binary phase codes in Radar pulse compression. Pulse compression allows radar to use long waveforms in order to obtain high energy and simultaneously achieve the resolution of a short pulse by internal modulation of the longpulse. This technique increases signal bandwidth through frequency or phase coding. This paper does a comparative analysis of binary codes based on the simulation results of their autocorrelation function and identifies 13 bit Barker code as the most optimal binary code for surveillance radar.

Implementing NAND Flash Controller using Product Reed Solomon code on FPGA chip Abstract: Reed–Solomon (RS) codes are widely used to identify and correct errors in storage systems and transmission and. When RS codes are used for so many memory system and reduces error in data. (255, 223) product ReedSolomon (RS) for non-volatile NAND flash memory systems.
Reed-Solomon codes are the most used in digital data storage systems, but powerful for tool burst errors. To correct multiple random errors and burst errors in order, The composing of product code in to column-wise RS codes and row-wise RS codes may allow to decode multiple errors beyond their error correction capability. The consists of proposed code is two shortened RS codes and a conventional Reed-Solomon code.The nonvolatile NAND flash Controller memory systems. Reed-Solomon codes are the most Powerful used in data storage systems. The proposed coding scheme on a FPGA-based simulator with using an FPGA device. The proposed code can correct 16 symbol erro.
