• ### Differences in 4-Year Health Outcomes for Elderly and Poor, Chronically III Patients Treated in HMO and Fee-for-Service Systems

Height and weight of the subjects were measured using standard procedures. The weight was measured using SECA balance with minimum of cloths to the nearest of 100 gms and height was measured using an anthropometric rod to the minimum of 0.5 cm. Body mass index (BMI : weight in kg/height in meters2 ) was calculated from heights and weights. A value ≤ 18.5 is considered as a cut-off point for chronic energy deficiency (CED) or undernutrition (thinness), while BMI ≥ 25 is considered as overweight or obese. Prevalence of diseases in both groups separately was calculated.

• ### EC&M’s Electrical Calculations Handbook

Electricity is an invisible force that is used to transfer energy into heat, light, intelligence, or motion. Electricity is explained in terms of electrical charge, potential differ- ence (or voltage), electrical charge flow (or current), and resistance to current flow. Figure 1-1 graphically illus- trates electron flow through a conductor by comparing it with water flow through a pipe. The normal unit of current measurement is the ampere, whereas the normal unit of voltage measurement is the volt. The unit of opposition to current flow, or resistance, is the ohm...

• ### 101 Steps to Success

Most people want to be successful in life. There are goals set and then the hard work begins to reach those goals. The question is what is success? Actually, success can mean different things to different people. For example, a person that owns their own oil changing service for vehicles might set their level of success at servicing 50 cars a day while someone who loves music might consider success as cutting their own CD. In addition, success does not always have to involve money. Success could be getting a good grade in a difficult class or learning how to...

• ### Voltammetry

Voltammetry techniques measure current as a function of applied potential under conditions that promote polarization of a working electrode. Polarography: Invented by J. Heyrovsky (Nobel Prize 1959). Differs from voltammetry in that it employs a dropping mercury electrode (DME) to continuously renew the electrode surface. Amperometry: current proportional to analyte concentration is monitored at a fixed potential

• ### ECG in the Child and Adolescent

Electrocardiograms (ECGs) are the graphic representation of body surface potential differences generated by the electrical activity of the heart. Bipolar limb leads, augmentedunipolar limb leads and precordial leads have been used routinely for recording the ECG, which remains an essential part of the cardiac examination, even after the advent of cardiac catheterization, angiocardiography, echocardiography and many other sophisticated diagnostic modalities.

• ### Sách: Fatty Liver Disease: NASH and Related Disorders

Non-alcoholic fatty liver disease (NAFLD), like hepatitis C and HIV, is a disease of our generation. Mostly unrecognized prior to 1980 and seldom taken seriously until the past few years, NAFLD has seemingly been thrust upon us unexpectantly like an orphaned child left at our clinical bedside. In fact, NAFLD was conceived during the industrial revolution, which caused food to be processed differently, provided that food more abundantly and made physical work less demanding.

• ### The Potential for Scale and Sustainability in Weather Index Insurance

This publication consists of six parts. The first part is intended to provide readers with an overview of the insurance sector from the perspective of developing countries.

DC as well as AC circuit analysis is provided with a brief account of filters in the end.

The prominence of private health insurance has been buttressed by government interventions directed at PHI markets in several OECD health systems, although the effectiveness of policies aimed at increasing market size and fostering outcome quality has differed widely. Australia, Ireland, the Netherlands, Germany, Switzerland and the United States have promoted and maintained a large and viable private health insurance market because policy makers have concluded that mixed public-private coverage systems can better deliver desired health policy and social outcomes.
