A comparative study between visual, near infrared and infrared images for the detection of veins for intravenous cannulation

The process of identification and locating of veins plays an important role to reduce health care cost and suffering of patients during intravenous cannulation. This paper compares between three technologies to assess their suitability and capability for the detection of veins. Three types of cameras are used in this study, a visual camera, an infrared camera and a near infrared camera. The collected data has then been subjected to analysis and comparison using different image processing techniques, namely grayscale, invert grayscale, histogram equalisation, edge detection (difference of Gaussians) and unsharp mask enhancement to improve the visualisation of veins. In this study, the near infrared images supported by suitable LED illumination has been found to be the most effective technology and the most cost effective for the visualisation of veins

Strategi Dinas Pemberdayaan Masyarakat dan Desa dalam Pelaksanaan Program Kampung KB di Desa Lipukasi Kecamatan Tanete Rilau Kabupaten Barru

This study aimed to find out how the KB village Kampung Program Implementation Strategy in The Lipukasi Village, Tanete Rilau District, Barru Regency. This study used a qualitative descriptive research method system. Data collection techniques were observation, interview and documentation. While data analysis used data reduction, data presentation and drawing conclusions. The result of this study showed that The Strategy in Implementing the KB Village Program in Lipukasi Village, Tanete Rilau District, Barru Regency had been running quite well, this could be seen with the number of KB village programs that had been implemented. However, constraints occurred in the Implementation such as community participation, budget and communication of each agency was still not optimal. This happened because of the lack of communication between agencies as well as the lack of cooperation between Implementers and related agencies which caused constrained activitie

The biosensitivity of certain organs in rats exposed to low doses of γ-radiation

AbstractTrace elements as Fe, Cu, Zn and Ca are essential for life. They approximately involved in all living processes, they play an important role in the hormones and enzymes activities. The present study demonstrate the biosensitivity of certain organs (spleen, intestine, heart and brain) in rats exposed to low doses of γ-radiation by determine the effectiveness on essential metal levels. Rats were exposed to 0.06, 0.126 and 0.227 Gy as a total doses at a low dose rate 2.5 mGy/h by two models of exposure, continuous and fractionated (along one and two weeks). Results indicated that the metal levels affected by the time exposure and organ sensitivity. Continuous exposure manifested increase in brain Fe, spleen Cu and Ca and decrease Ca in intestine and brain at all doses. After one week, intestine Cu and heart Zn decreased. After two weeks, decrease in Fe levels was observed in intestine, heart and brain at all doses. Also heart Zn and brain Ca decreased, Ca heart increased where Cu exhibit elevation in spleen and lowering in intestine at all doses. The statistic analysis presented significant effect between groups according the time factor and/or dose levels on Fe and Ca in all organs. Also significant effect present in Zn levels due to the time factor and/or dose levels in all organs except intestine. In conclusion, the rat organs have been responded to the low doses of γ-radiation at low dose rate by significant changes in essential metals concentrations

Flowfield-dependent variant method for moving-boundary problems

A novel numerical scheme using the combination of flowfield-dependent variation method and arbitrary Lagrangian–Eulerian method is developed. This method is a mixed explicit–implicit numerical scheme, and its implicitness is dependent on the physical properties of the flowfield. The scheme is discretized using the finite-volume method to give flexibility in dealing with complicated geometries. The formulation itself yields a sparse matrix, which can be solved by using any iterative algorithm. Several benchmark problems in two-dimensional inviscid and viscous flow have been selected to validate the method. Good agreement with available experimental and numerical data in the literature has been obtained, thus showing its promising application in complex fluid–structure interaction problems

Comparison of high-order accurate schemes for solving the nonlinear viscous burgers equation

In this paper, a comparison between higher order schemes has been performed in terms of numerical accuracy. Four finite difference schemes, the explicit fourth-order compact Pade scheme, the implicit fourth-order Pade scheme, flowfield dependent variation (FDV) method and high order compact flowfie ld dependent variation (HOC-FDV) scheme are tes ted. The FDV scheme is used for time disc retization and the fourth-order compact Pade scheme is used for spatial derivatives. The solution procedures consist of a number of tri-diagonal matrix operations and produce an efficient solver. The comparisons are performed using one dimensional nonlinear viscous Burgers equation to demonstrate the accuracy and the convergence characteristics of the high-resolution schemes. The numerical results show that HOC-FDV is highly accurate in comparison with analytical and with other higher order schemes

The modified Adomian decomposition method for solving Chaotic Lü system

In this paper, a numerical scheme based on adaption of standard adomian decomposition method (ADM) is applied to thechaotic Lü system. Then, the standard ADM is converted into a hybrid numeric-analytic method called the modified ADM (MADM). Numerical comparisons with the standard ADM and the fourth-order Runge-Kutta method (RK4) is made in order to prove that MADM is the reliable method for nonlinear problems
