Cross Sections A cross section is the shape we get when cutting straight through an object. The cross section of this object is a triangle. It is like a view into the inside of something made by cutting through it.

Cross-sectional study In medical research and social science, a cross-sectional study (also known as a cross-sectional analysis, transverse study, prevalence study) is a type of observational study that analyzes data from a population, or a representative subset, at a specific point in time—that is, cross-sectional data. In economics, cross-sectional studies typically involve the use of cross-sectional regression, in order to sort out the existence and magnitude of causal effects of one or more independent ...

How to Calculate Vector Cross Product A vector is a mathematical construct that has magnitude and direction. The cross product of two vectors is a binary operation in three-dimensional space that results in a third vector that is perpendicular to the plane that contains the two input vectors.

The Sahel Traditionally, most of the people in the Sahel have been semi-nomads, farming and raising livestock. Most people that live in the Sahel walk, bike, or sometimes drive an animal driven cart to get where they want to go. People who live in major cities in the Sahel ride buses, cars, and trains.

Euclidean vector The cross product (also called the vector product or outer product) is only meaningful in three or seven dimensions. The cross product differs from the dot product primarily in that the result of the cross product of two vectors is a vector.

- Home Contents Index. Volume by cross sections, Disc method, Shell method, Washer method. A solid of revolution is a solid figure obtained by rotating a plane region about a straight line that lies in the same plane. The term cross section is used to describe a slice of a solid of revolution, the slice being perpendicular to the axis of revolution. The volume of the solid of revolution can be computed by summing (possibly with an integral) the volumes of all of its slices.

cesarean section A cesarean section is a surgical procedure in which incisions are made through a woman's abdomen and uterus to deliver her baby. Cesarean sections, also called c-sections, are performed whenever abnormal conditions complicate labor and vaginal delivery, threatening the life or health of the mother or the baby. In 2003, about 27% of U.S. deliveries were cesarean, up 6% from 2002.

Cross section The purpose of the cross section is to determine which horizon can serve as the datum. Because it is shown as horizontal, the thickness variations of the units directly above and below the datum are most simply interpretable on the cross section.

Cross Tested Profit Sharing Plan Cross Tested Profit Sharing Plan. Cross-testing is a plan design concept which allows a company to define classes of employees and contribute profit sharing contributions on a percentage basis to each class. Cross-testing works best in a company which has a business owner who is slightly older than the rest of the employees.

Cross-multiplication Procedure [edit]. In practice, the method of cross-multiplying means that we multiply the numerator of each (or one) side by the denominator of the other side, effectively crossing the terms over. The mathematical justification for the method is from the following longer mathematical procedure.

Summary 1 A transverse plane, also known as an axial plane or cross-section, divides the body into cranial (head) and caudal (tail) portions. 2  It is parallel to the ground, which (in humans) separates the superior from the inferior, or put another way, the head from the feet.ovement at the joint take place in a plane about an axis. There are three axis of rotation. 1  Sagital axis-passes horizontally from posterior to anterior and is formed by the intersection of the sagital and transverse planes.

What is difference between cross-sectional data and panel data? Popular Answers. I'd add that there is also a type of data that's in between cross-sectional data and panel data. It is typically called repeated cross-sections or pooled cross-sections. For example, annual labour force surveys are repeated cross-sections, because every year, a new random sample is taken from the population.

Cross Section Cross Section of a Cone. The cross section is the shape obtained by a cut through a solid perpendicular to the length. A cone is pyramid with a circular cross section. The double cone is a quadratic surface and each single cone is called a nappe. The cross section of a conic section depending upon the relationship between the plane and the slant surface of the cone, the section may be a circle, a parabola, an ellipse or a hyperbola.

Cross-Tested Plans Overview Cross-Tested Plans Overview. 1  A Cross-Tested Plan is a form of a Profit Sharing Plan where allocations are based on both age and compensation and allows for different allocation rates among different classes of employees (new comparability plan) or is allocated in a manner that solely takes into account age (age-weighted plan).

test cross test cross. A test cross is a way to explore the genotpye of an organism. Early use of the test cross was as an experimental mating test used to determine what alleles are present in the genotype. An organism's genetic makeup is called its genotype, and it reflects all of the alleles, or forms of the gene, that are carried by the organism. Consequently, a test cross can help determine whether a dominant phenotype is homozygous or heterozygous for a specific allele.

Cross-Sectional Research Method: How Does It Work? Defining Characteristics of Cross-Sectional Studies. Think of a cross-sectional study as a snapshot of a particular group of people at a given point in time. Unlike longitudinal studies that look at a group of people over an extended period, cross-sectional studies are used to describe what is happening at the present moment.

PGE rate Hikes PGE increased the rate of residential power by roughly $.01 in tier 4,5. These are the old rates from Jan 1st-April 30th 2013. These are the new rates as of May 1st 2013. The weighted increase across all tiers would be $.00328 which would equate to $944,640 daily or $344,743,600 annually, wahoo for shareholders of PGE! This has been happening for decades, however the rate payers of PGE now have a solution to their increasing electric bills.

Physiological cross-sectional area The green lines represent PCSA; the blue lines represent ACSA. In muscle physiology, physiological cross-sectional area (PCSA) is the area of the cross section of a muscle perpendicular to its fibers, generally at its largest point. It is typically used to describe the contraction properties of pennate muscles.

Cross-sectional Studies A cross-sectional study may be purely descriptive and used to assess the frequency and distribution of a particular disease in a defined population. For example a random sample of schools across London may be used to assess the burden or prevalence of asthma among 12-14 year olds. 1  Analytical. cross-sectional study should be representative of whole the population, if generalisations from the findings are to have any validity. For example a study of the prevalence of diabetes among women aged 40-60 years in Town A should comprise a random sample of all women aged 40-60 years in that town.
