here METHODOLOGY IN DEVELOPING A NEW MULTI-FREQUENCY IMPEDANCE TECHNIQUE TO DETECT BLOOD IN DENGUE PATIENT The developmentof Multi-frequency Impedance system has continued together with
additional hardware as well as extensive software development and below are the detailed procedures in the establishment of the method.
1. The measurable of frequency range may be within the range of 5Hz up to 5MHz. Where needed, impedance values can be translated into SI units, so it would be easier to present both in tabular form and graphical. This will permit easy comparison. Bioimpedance can be measured by loading impedance range in a measure of 100 to 10k.
2. Two leads will be used in order to drive currents into the medium, at the same time acquire potential difference measurements. Note that this procedure will utilize blood. Blood is a living tissue composed of cells and fluid plasma. This plasma consist of the liquid part containing the electrolytes as well as large organic molecules which are electrically polarized. Molecules. In hemolyzed blood, red blood cells (RBC) are disrupted , so with their intracellular material that being is discharged into the liquid. Thus, the electrical properties of the blood and the haemolyzed blood are basically very different. Whole blood presents , and dispersion, however, almost no dispersion (Schwan, 1983). RBCs are not good conductors of electrical current in a low frequency range as compared with the plasma or extracellular medium which surrounds them.
3. In this method, 0.01-0.001% of heparin will be used to avoid coagulation Burger and Van Milaan (1943)

4. Impedance measurements of a human blood sample at 1kHz and at 37C shall be set
using two terminals and also an impedance bridge (Rosenthal and Tobias, 1948)
5. To avoid sedimentation effects, two terminal experiment setup which will included a horizontal cylinder measurement cell design shall be employed. The cylinder measurement cell design basically will allow laminar blood flow. Other than the cylinder, sophisticated instrument may also be used;
6. The TAS system will be very significant instruments in the experimental process and shares with the multi-frequency system which is developed by Oh, et al (2006). These instruments include: PC with USB port, TAS software, intra-network controller, main controller with USB interface, multiple ammeters, constant sinusoidal voltage source, hand-held electrode, switches, scan probe of electrodes, and dc power supply. .
7. Resistor phantom will be used to calibrate each ammeter for the various gains and frequencies. The 32 different gains is usually used during the multi-frequency operation.
8. Then, saline phantom will contain the anomaly blood; while disc-shaped reference electrode must be contained at the bottom of the phantom.
9. Frequencies can be set in the range of 10 Hz to 500 kHz.

Amplitude & Frequency Modulation Techniques

... the number of modulation indices. For AM, the maximum efficiency possible without distortion is only 33% (at modulation index = 1). FM has almost limitless number of modulation indices and the power of the sidebands are just fractions of the total power in an FM signal (Kennedy and Davis, 1993). Disadvantages of Frequency Modulation 1. Excessive Bandwidth Utilization. Since there is no natural limit to the modulation indices in FM as compared to FM, the tendency is to increase it resulting to excessive bandwidth requirement. This may not be possible in actual communication systems because of telecom regulation issues (Kennedy and Davis, 1993). 2. Circuit Complexity. FM has inherent advantages over AM in terms of noise immunity...

High frequency trading

Module Demerits of High Frequency Trading Those that get involved in high-frequency trading are aware of the impact it has on them. For the average investor, there are concerns that HFT is making things difficult and volatile for them instead of leveling the playing field for everyone (Aldridge 60). The problem arises when companies have to continue making use of their complex computerized algorithms to meet the main demands of the investors. They can quickly identify the ability of an individual wanting to buy shares, and buy them ahead of the trader and sell at higher prices (Kirilenko, Kyle, Samadi & Tuzun 22).
Another disadvantage that faces the average investor is the ability to withdraw and initiate thousands of trades a...

Budgetary Control and Costing System

Job costing and Process Costing are the two basic methods of costing. Job costing is suitable to industries, which manufacture or execute the work according to the specifications of the customers. Process costing is suitable to industries where production is continuous and the units produced are identical. All other methods are combinations, extensions or improvements of these basic methods.

1. JOB COSTING: It is also called specific order costing. It is adopted by industries where there is no standard product and each job or work order is different from the others. The job is done strictly according to the specifications given by the customers and usually, the job takes only a short time for completion. The purpose of...

Comparison of the Cold War International System to the Current International System

An example is that of the Korean War (1950-53) which is said to transform the nature of the Cold War, while its initial impact was to solidify the division of the world into political, military, and economic spheres. Take Germany for instance where imperialism was a victim challenged by the historians for the destruction of the German Government along with its supporters used to conduct (Keylor, 2001, p. 44). That indicates economic expansion and territorial acquisition has always been a problem promoted since the First World War. Even in the 1920s, it was fashionable to declare the German empire on the threshold of the ‘Great War’ (Keylor, 2001, p. 44).

Europe in the global context remained tense and divide...

The Interprofessional Practice and the Health Care System

This is also the position Stone (2007) takes in the quote under discussion.
Furthermore, Stone goes on to declare that Australia has been very slow to implement this practice as compared with other countries and government agencies. One of the primary reasons is that the public policy system in Australia is quite complex and the decision-makers have not come into agreement on where to place it in the policy matrix. This leaves Interprofessional Practice and Education in the dark (or the cold) as far as strategic planning for implementation as well as placing itself within the funding cycles of the government disbursements. (Stone, 2007)
Policies are created in order to put in place how politicians and government official...

Comparative Review of Welfare System

In order to compare the welfare system of the three proposed countries, it is important to first develop a comparative method that would guide in comparing the three states. For the purpose of this paper, a binary comparison would be conducted. The implicit comparison would deal with Britain while the explicit comparison would explore the USA and Canada. Thereby a small N’ study would be used, that is, of three countries.
The three countries selected to share a similarity in the form that these countries are a welfare state. This is when welfare is mainly funded by the state. While the USA and Canada focus on the liberal welfare state, the welfare state of the UK is not quite defined.
