2.) Because it’s a observational research techniques done to study the relationships of variables which can run for a long period of time. These are also co-relational studies where data is collected from the start of these researches and repeated in the course of time. 3.) The strength of using this form of research is that it can help find patterns that may occur over long periods‚ but would not be observed over short periods. Changes can be tracked so that cause and effect relationships can

Child mortality in Madhya Pradesh : a cross sectional analysis The millennium development goals (MDGs) have been widely accepted as a framework for improving health and welfare worldwide. Child mortality is one of the most crucial and avoidable global health concerns. In many low income countries‚ 10-20% of children die before reaching 5 years of age . The child mortality in MDG (to reduce the under 5 mortality rate by two thirds between 1990 and 2015) is formulated as a national average.(UN- child

Sound is a vibration that spreads across a medium (i.e.‚ air or water) as a mechanical longitudinal wave formed by pressure. A Mechanical longitudinal wave can also be called compression wave as it generates compressions and rarefaction when traveling through a medium. (Sound Is a Pressure Wave - Physics Classroom) The amplitude of a sound wave is the difference between the pressure of the undisturbed air and the maximum pressure caused by the wave. The Speed of sound deviates with the temperature

Waves are mainly known for their way of transferring energy from one place to another without transferring any matter.Transverse and longitudinal are waves in which can be related to one another in some kind of way. A transverse wave is a wave in which vibrates perpendicular to the direction of the waves motion. As a transverse wave travels through a medium‚ the individual particles of the medium move perpendicular to the direction of the wave travel. They may occur in a string‚ in the surface of

Theory of Longitudinal Static Stability Stick Fixed Stability (tailless aircraft) An aircraft that has elevons (combined ailerons and elevators) e.g.‚ Concorde is governed by slightly different equations. The effect of the tab angle is usually ignored as most tailless aircraft have powered controls and so no tabs. The lift equation therefore becomes Moments about the cg give us: For TRIM‚ the elevon angle to trim is [pic] For STABILITY it is clear that the aerodynamic

The Cross Is it Christian or Pagan? Most people view the cross as a symbol of Christianity. But in direct contrast‚ the Bible never describes the device of Jesus’ execution‚ not allowing anyone to know its shape exactly. However‚ the Bible and multiple studies provide compelling evidence that Jesus died on a stake. The word stauros‚ Greek in origin‚ is used most commonly when referring to the device used for Jesus’ death. The Bible uses the word xylon as a comparative word for stauros. Translating

Longitudinal and transverse waves Sound is transmitted through gases‚ plasma‚ and liquids as longitudinal waves‚ also called compression waves. Through solids‚ however‚ it can be transmitted as both longitudinal waves and transverse waves. Longitudinal sound waves are waves of alternating pressure deviations from the equilibrium pressure‚ causing local regions of compression and rarefaction‚ while transverse waves are waves of alternating shear stress at right angle to the direction of propagation

three years of experience. I run the sectionals at each practice conducting and helping with fingerings‚ rhythms‚ and overall sound. My section is not afraid to ask me questions and i usually ask them if there is anything they need to go over. Not only do I run sectionals for marching band but I have also taken the initiative to have sectionals for concert band as well. Although it is not a requirement for my grade and also was not asked of me‚ I would have sectionals with the students from concert band

Slavery: A Sectional Issue From the time of the first exploration of the New World to the eve of the Civil War‚ slavery played a significant role in the development of the United States. Before the American Revolution‚ the North and South both practiced slavery. Whether the first African Slave trade between England and the West African Coast‚ or the last slave trade where Virginia and Carolina profited by selling slaves to the black belt states‚ slavery was a dominant presence for nearly

SECTIONAL AND SELF BALANCING SYSTEM Introduction: After the transactions‚ being recorded in the journal‚ are classified in the ledger. A small enterprise normally has less number of accounts are therefore can maintain all the accounts in one ledger alone. However‚ in case of a big enterprise‚ the number of accounts are large and‚ therefore‚ it becomes inconvenient to maintain all accounts into one ledger alone. Hence in such a condition the ledger is sub-divided into the following three ledgers:
