Health Field Model A model of the determinants of health proposed by Evans and Stoddart�the health field model�provides a broad conceptual framework for considering the factors that influence health in a community (Evans and Stoddart‚ 1990). Unlike a biomedical model that views health as the absence of disease‚ the field model includes functional capacity and well-being as health outcomes of interest (see Figure 1). The model also emphasizes general factors that affect many diseases or the health

physics of the electromagnetic field‚ a field that exerts a force on particles with the property of electric charge and is reciprocally affected by the presence and motion of such particles. A changing magnetic field produces an electric field (this is the phenomenon of electromagnetic induction‚ the basis of operation for electrical generators‚ induction motors‚ and transformers). Similarly‚ a changing electric field generates a magnetic field. The magnetic field is produced by the motion of electric

HYDROSTATIC FORCE (EXPERIMENT 1) INTRODUCTION The determination of force which are exerted by liquid which are at rest on surface immersed in liquids. From the study by hydrostatic‚ the following principles have been established : a) There are no shear stress present when the fluid is not in motion. b) The pressure exerted by a fluid under hydrostatic conditions. This pressure acts perpendicular to an immersed surface. c) Hydrostatic pressure various linearly‚ increasing with an

Summary: Experiment 9 is conducted to identify the importance of intermolecular forces and how they affect molecules. Intermolecular forces are forces between molecules that determine whether the molecule is a solid‚ liquid‚ or gas under standard conditions. In our lab‚ we measured the maximum and minimum temperature reached and time it took to reach it of alcohols and alkanes. In addition‚ we measured the vapor pressure of the liquid at different temperatures. Through Experiment 9‚ we concluded

Connecticut State Department of Education (CSDE)‚ poverty is defined “for each school using the percentage of students eligible for free/reduced-price meals based on the student data collected in its Public Student Information System (PSIS).” Annual analysis of this data determines‚ among other things‚ the percentage of each school’s students living in poverty. This information is then used to separate school districts into quartiles of high and low poverty‚ which are used for further analyses and determination

Natural Forces A natural force is a power brought on by nature. Natural forces‚ unlike those of other powers‚ are uncontrollable. When a hurricane passes along the coast‚ a bolt of lightning strikes a rooftop‚ and a volcano erupts‚ these are all examples of natural forces. Natural forces can have devastating effects on wildlife‚ humans‚ and the earth itself. Our effects to resist these occurrences‚ our only way to cope with such devastating forces of nature are to observe‚ learn‚ and prepare

FORCE AND MOTION Scalars vs. Vectors Scalars | Vectors | A scalar quantity has only magnitude. | A vector quantity has both magnitude and direction. | Scalars can be added‚ subtracted‚ multiplied and divided just as ordinary numbers‚ i.e.‚ scalars are subjected to simple arithmetic operations. | Vectors cannot be added‚ subtracted and multiplied following simple arithmetic laws. Arithmetic division of vectors is not possible at all. | Example: mass‚ volume‚ time‚ distance‚ speed‚ work‚ temperature
