The Influences of Sintering Process on the Characteristics of Corbiculacea (Etok) Shells Based Hydroxyapatite Powder

Hydroxyapatite (HA) powders were prepared via chemical solution through aqueous solution of calcium hydroxide and phosphoric acid. The calcium precursor was extracted from the calcium carbonate of Corbiculacea shells while the phosphate precursor originated from the commercially available phosphoric acid. The final product of HA powders is then manipulated through the sintering process at 500°C while the other sample was used as it is. XRD result shows significant changes in its crystallinity, crystallite size and lattice parameters after the sintering process. By sintering the HA, the crystallite size and crystallinity were increases as much as 6.25% and 5.31% respectively. SEM on the other hand showed different morphology for both sintering and non-sintering HA powders. For the sintering HA, the grains size is higher which is 5. 00μm compared to non-sintering HA which is 3. 91μm due to the agglomeration.
Optimal reactive power planning and its spot-pricing: an integrated approach

The paper presents an integrated framework to analyze the issues of reactive power planning along with reactive power pricing. The planning problem involves optimal placement and sizing of capacitors in a network such that operating and investment costs are minimum. A simple bus-wise cost-benefit analysis (CBA) scheme is proposed which involves solving a modified optimal power flow problem (OPF) iteratively. The proposed CBA incorporates detailed hourly loading conditions at a bus and achieves a fairly accurate estimate of the benefits from capacitor placement. The formulation is directly handled by the well known MINOS code and is solved efficiently. It obviates the need to introduce integer variables and is thus suitable for large system applications. A two-part reactive power spot-pricing scheme is formulated, by which the investment and operational costs can be recovered by the utility. The proposed reactive power price has two parts-a fixed part to account for the investment costs of new capacitor at a bus and a variable spot price to account for the operating costs incurred in supplying the additional reactive power from generating units.

Fast and accurate synthesis of electronically reconfigurable annular ring monopole antennas using particle swarm optimisation and artificial bee colony algorithms

The synthesis of a simple electronically reconfigurable annular ring monopole antenna using a designing optimisation process based on particle swarm optimisation (PSO) and artificial bee colony (ABC) algorithms is proposed. Several antenna dimensions are selected as objective functions of PSO and ABC and their best solutions are considered as the optimised dimensions of the antenna geometry. Two radio-frequency p–i–n diodes, connecting the antenna feeding line to two microstrip stubs are used to change the antenna frequency response from ultra-wideband (UWB), from 3.1 to 10.6 GHz, to narrowband (NB) operation about 5.8 GHz. The antenna design and simulation are performed using Ansoft high-frequency structure simulator software. PSO and ABC algorithms are written in Java language. Thereafter, antenna prototypes are fabricated and measured for validation purposes. Simulation and measurement results are obtained showing good agreement. The measured optimised impedance bandwidths of the UWB and NB bands are up to 128 and 23%, respectively. Additionally, simulated and measured radiation patterns are very similar when the reconfigurable antenna is operating in OFF-state (UWB sensing antenna) and in ON-state (NB transmitting antenna) modes, indicating the proposed antenna geometry as a promising candidate for applications such as UWB and cognitive radio.

In this paper, the maritime terrorist threat is introduced and an updated status of the U.S. government's response to the threat through organizational change is documented. Some of the more recent changes within the U.S. Coast Guard that affect the nation's posture against maritime terrorism are presented. A list of some of the first responders and supporting organizations to a maritime security incident is provided. A plausible incident scenario is used to illustrate the resulting flow of information and the need to rapidly disseminate data to the first responders to help them to be both safe and effective.
An Image Pre-Processing Improvement Procedure for Standardizing Multiple Colour Variations in the Astrocytoma Immunohistochemical Staining Images

Colour variations in the histopathological images can occur when the acquired images came from different laboratories. This issue happens may be due to different protocols between each laboratory. Besides that, the usage of dye or staining is also different since it arrived from different manufacturers. Hence, it will affect the performance of a system, especially for an automated image diagnosis system. If this issue is taken lightly, the whole process of image analysis can produce a false diagnosis outcome, and thus, it will affect the patient’s treatment options and endanger the patient’s life. This paper proposed an automated image pre-processing procedure for standardizing the colour variations in immunohistochemical staining images. The proposed procedure was done by modifying the reference image, which will be used later for the stain standardization process. Based on 50 astrocytoma histopathological images, the proposed procedure showed a promising result, where the quality of the output images has been enhanced and standardized.
Corporate Waste Management : What practices do leading MNCs ’ implement ?

Waste production and management is a topic of great social and political interest given its link to environmental deterioration and current trend towards sustainable lifestyles. In this context, corporate behaviour, especially of multinational companies (MNCs), is looked at. The objective of this study is to assess MNCs’ waste management (WM) policies, identify which type of waste companies prioritise and, based on this, ‘best practices’. Based on the qualitative analysis of practices implemented by four MNCs ranked as sustainability leaders, findings show companies focus on emissions and solid waste. Techniques applied involve transitioning to renewable energy, improving energy efficiency, replacing plastic and implementing recycling schemes; focusing on the main type of waste generated. On the other hand, efforts towards better water use and wastewater generation are not widespread. The study contributes to existing research about corporate sustainability, specifically on WM, and provides examples for companies introducing or improving their WM policies.
J ul 2 00 1 Introduction to M ( atrix ) theory and noncommutative geometry

Noncommutative geometry is based on an idea that an associative algebra can be regarded as ”an algebra of functions on a noncommutative space”. The major contribution to noncommutative geometry was made by A. Connes, who, in particular, analyzed Yang-Mills theories on noncommutative spaces, using important notions that were introduced in his papers (connection, Chern character, etc). It was found recently that Yang-Mills theories on noncommutative spaces appear naturally in string/M-theory; the notions and results of noncommutative geometry were applied very successfully to the problems of physics. In this paper we give a mostly self-contained review of some aspects of M(atrix) theory, of Connes’ noncommutative geometry and of applications of noncommutative geometry to M(atrix) theory. The topics include introduction to BFSS and IKKT matrix models, compactifications on noncommutative tori, a review of basic notions of noncommutative geometry with a detailed discussion of noncommutative tori, Morita equivalence and SO(d, d|Z)-duality, an elementary discussion of instantons and noncommutative orbifolds. The review is primarily intended for physicists who would like to learn some basic techniques of noncommutative geometry and how they can be applied in string theory and to mathematicians who would like to learn about some new problems arising in theoretical physics.
Preferential centrality as a multi-regional model for spatial interaction and urban agglomeration

Understanding how transportation networks affect regional development has been a long-standing challenge for modellers in several disciplines, both in research and practice. Approaches span between light-weight accessibility and centrality models, to data-heavy land use-transport interaction models. Centrality models have been increasingly employed to support spatial planning on the city-scale, where such techniques are attractive due to their low requirements of socioeconomic and demographic data, while they also maintain representations of essential features such as accessibility. However, it has been less clear if such approaches can be successfully extended from the urban to the regional scale. In this paper we demonstrate how a recently introduced centrality measure – preferential centrality – can be used as a modelling framework on the multiregional scale, while retaining high intra-urban spatial resolution. Centrality is calculated on a zonal level, with local plot characteristics and network travel times as input. Preferential centrality is calculated similarly to Google PageRank and eigenvector centrality, but with preferential growth as an additional component that represents local agglomeration processes. To examine the explanatory power of this approach, we compare computed centrality with empirical land taxation values, using the southern half of Sweden as a case study area. Using a static accessibility model as benchmark, we find that the preferential model has a higher capacity to reproduce empirical patterns, with regard to geographical correlations as well as for probability distributions. Our findings suggest that preferential centrality analysis can have practical value in urban and regional planning contexts, for example when assessing the geographical distribution of impacts from transport infrastructure investments. 1 alexander.hellervik@chalmers.se
Frequency of Non-Alcoholic Fatty Liver Disease in Patients with Type 2 Diabetes Mellitus and Its Relationship with Glycemic Status: an Observational Study

Background: Non-alcoholic fatty liver disease (NAFLD) and type 2 diabetes mellitus (T2DM) may coexist in many individuals. This study was conducted to observe the frequency of NAFLD in Bangladeshi T2DM patients and to compare the glycemic status in T2DM patients with and without NAFLD. Materials and methods: Total 80 (eighty) previously known cases of T2DM were included as per inclusion and exclusion criteria. All patients underwent abdominal ultrasound to detect fatty liver. NAFLD was diagnosed after excluding other causes of liver diseases. Clinical and biochemical data were recorded and compared among T2DM patients with and without NAFLD. Results: Overall frequency of NAFLD in T2DM was 60%. Frequency among male and female T2DM patients was comparable (58.1% vs 62.2%, P 0.714). Frequency increases with age and highest frequency was found in age group 50-59 years (62.2%). Body mass index (BMI) and SGPT were significantly higher in NAFLD compared to non-NAFLD where age, duration of diabetes, fasting plasma glucose (FPG), plasma glucose 2 hours after breakfast (ABF) and HbA1c were comparable (BMI 27.8±4.9 vs 24.7±3.2 kg/m 2 , P 0.006; SGPT 47.0±25.3 vs 31.9±13.3 IU/L, P 0.001; age 52.5±8.2 vs 51.1±9.2 years, P 0.349; duration of DM 5.1±3.8 vs 5.7±3.1 years, P 0.460; FPG 9.1±2.8 vs 9.4±2.1 mmol/L, P0.220; ABF 14.7±4.8 vs 14.8±3.6 mmol/L, P 0.092; HbA1c 8.9±1.9 vs 8.8±1.2%, P 0.065 respectively). Conclusions: NAFLD is very common in Bangladeshi T2DM patients. Degree of hyperglycemia is comparable in T2DM patients with and without NAFLD.

Human Dimensions of Research in the Sonoran Desert: Next Generation Sonoran Desert Researchers

Next Generation Sonoran Desert Researchers (N-Gen) is a growing community of researchers dedicated to the study of society, culture, geography, and ecology in the Sonoran Desert. It was formed to facilitate communication and collaboration among early-career researchers in the region, as well as to support connections and build bridges between this new group and later-career researchers. In April 2012 N-Gen hosted an inaugural summit in Tucson, Arizona. Participants came from Mexico and the United States, representing 16 different disciplines and 37 different institutions, including nongovernmental organizations, academia, indigenous communities, and government agencies. The overarching goal of the summit was to establish lasting connections and develop a network of collaborators from a group that was previously largely unconnected. Before N-Gen there was no organized network for Sonoran Desert researchers. Further, our understanding of the networks connecting those working in the region was limited. With few exceptions (see Marcos-Iga’s 2004 master’s thesis looking at networks of conservation organizations in the Colorado River Delta and Laird-Benner and Ingram’s 2011 study of network “weavers” in the U.S.-Mexico border region of Arizona and Sonora), little is known about how researchers in the Sonoran Desert are connected. Here we use social network analysis and cluster analysis to examine the patterns of connections between N-Gen summit participants (for a more detailed explanation of social network analysis and how it relates to natural resource management, see Bodin et al. 2006; Carlsson and
A STUDY OF MEASURING THE CRITICAL FACTORS OF QUALITY MANAGEMENT

Saraph et al. systematically attempted to organize and synthesize the various perceptions offered by other authors on the critical factors of quality management. The authors provided a synthesis of the quality literature by identifying eight critical factors of quality management in a business unit. They stated that the measures were both valid and reliable. In the light of this, empirically tests their resulting instrument to a greater extent and from an international perspective. The instrument of the operational measures of the developed factors is tested for reliability and validity using data collected from 424 general managers and quality managers in the United Arab Emirates. Results provide strong evidence that the measures are judged to be both valid and reliable. The empirical replication on a more broadly based sample provides further corroboration of Saraph et al.’s results. Examines the level of practice of factors of quality management in the UAE. Suggests that better use of the instrument is.
A Decentralized Positioning Method for Wireless Sensor Networks

The three-dimensional positioning algorithm has become a hot research direction in wireless sensor networks localization algorithms, however the existing 3D positioning algorithms have general shortcomings, such as high complexity, low positioning accuracy, great energy consumption. Aiming at the existing problems of 3D localization algorithm, we propose an decentralized 3D positioning algorithm based on RSSI ranging and free ranging mechanism. The algorithm firstly use measured RSSI to establish beacon node neighborhood. Then the method adopts regional division to obtain initial location information for unknown nodes. Finally, the method use the iterative optimization process to achieve a position information updates. Simulation results demonstrate that proposed algorithm is feasible and has better localization accuracy.
TOWARDS A LEAN INTEGRATION OF LEAN

Purpose The purpose of the research is to explore a practical method of measuring the implementation of lean in a process. The method will be based on examining the abilities of a group. At this scale the ability to work standardized and solve problems is important. These two abilities are dependent of each other and are fundamental for the group’s ability to create a stable result. In this context the method of standardized work (SW) is define to be the methods used in a process to generate stable results. Problem solving (PS) is defined as the methods used to return a process to a condition where SW is possible. Methodology / approach The research is conducted in a multiple case study in four large global manufacturing companies. The order of the data collection is: Firstly, interviews with the individuals that are centrally responsible for overall implementation of lean in the organization. Secondly, observe the implementation of SW and PS at the group level. In total 7 groups have been studied and 19 respondents interviewed. Findings Results show that the central definition of the methods for standardized work does not by itself have a direct impact on success of implementation of SW at group level. The method of SW where similar on a general level in the different cases, but with varying levels of implementation at group level. Results also show that key factors for a successful implementation of standardized work on group level are: Ownership of the process, Direct connection to result of process, Correct workload and Leader demand. Methods of PS at group level where dissimilar despite a superficially similar approach. The evaluation method used was successful in providing comparable results between the cases. Research limitations A limitation of this research is within the scale of the measurement, as it only examines the group level. The research is further limited to four companies and seven groups. Originality/value of paper This paper aims to fill a gap in the established measurement methods of lean, as it examines the abilities of SW and PS at the group level of a process. These abilities are often referred to as essential in lean theory. However, there has been little scholarly work in defining the methods of SW and PS or the key factors affecting the methods at an operational level.
Two-Step Optimization for Wind Turbine Blade With Probability Approach

A horizontal-axis wind turbine blade is designed using two step optimization procedures with probability approach. For the efficient management of the multiple design variables required for the blade design, the design procedure is divided into two optimization steps. In step 1, the diameter and rotating speed of a blade are determined and design points are extracted from the design space. In step 2-1, blade shapes are optimized by using the strip theory with the minimum energy loss method. The capacity factor and the cost model for each optimized blade shape are calculated in steps 2-2 and 2-3, respectively. To find the global optimum point in the design space, the space is modified into a highly possible region through the use of the probability approach.
