How to Determine the Sample Size in a Quantitative Research Determining the sample size in a quantitative research study is challenging. There are certain factors to consider and there is no easy answer. Each experiment is different with varying degrees of certainty and expectation. Typically there are three factors or variables one must know about a given study each with a certain numerical value. They are significance level power and effect
3 Technologies in Exploration Mining and Processing The most important factors determining whether surface mining can be done today are economic and technical— the price for the product the cost of production the quality and quantity of the deposit the volume of overburden to be removed per ton of the deposit and the feasibility of reclamation. The practice of surface mining is quite complex and can involve all or several of the following

Mining Techniques Geology for Investors Proximity to the surface plays a major role in determining which mining technique will be used. A small deposit near the surface may very well be economical if open-pit mining can be utilized. However the same deposit a few hundreds of meters below the surface may prove to be uneconomical due to costs associated with subsurface extraction.
Conversion factors - energy and carbon conversion guide Overview This guide and interactive spreadsheet provides a number of useful conversion factors to help you calculate energy consumption in common units and to work out the greenhouse gas emissions associated with energy use.
Radiation Quantities and Units One of the compli ing factors in determining CT dose is that the tissue in a slice is exposed to two sources of x-radiation. One is the direct beam and the other is the s tered radiation from adjacent slices in the typical multiple slice imaging procedure. It is the contribution from the s tered radiation that is very difficult to measure. Values for the CTDI are determined by a
Dimensions Units Conversion Factors and Significant Digits Dimensions Units Conversion Factors and Significant Digits . Introduction ; There is a difference between dimensions and units. A dimension is a measure of a physical variable without numerical values while a unit is a way to assign a number or measurement to that dimension.
Factors Affecting Construction Labor Productivity Factors Affecting Construction Labor Productivity 1 1. Introduction The measure of the rate at which work is performed is called “productivity”. It is a ratio of production output to what is required to produce it. The measure of productivity is defined as a total output per one unit of a total input.
Coal mining - Choosing a mining method Britannica Social factors include prior history of mining in the area ownership patterns availability of labour and local or regional government support.

Factoring Calculator Consider the number 10. Since 10 is evenly divisible by 2 and 5 you can conclude that both 2 and 5 are factors of 10. The table below lists the factors for 3 18 36 and 48. It is important to note that every integer number has at least two factors: 1 and the number itself. If a number has only two factors that number is a prime number.
Mining - Underground mining Britannica There are a number of reasons for this not the least of which is that the size of underground mining equipment—because of ground conditions ore body geometry and other factors—is much smaller than in the open pit. Also access is much more limited. All of this means that productivity as measured in tons produced per worker per shift can be 5 to 50 times lower depending on the mining
