  • After the ore is extracted, it is generally transferred by bridge conveyor, shuttle cars or load-haul-dump units to a system of conveyors that carry it to underground storage bins, prior to haulage to the surface through a shaft by automated skips. On rare occasions shallow mines may use a decline and conveyor arrangement. Solution mining is currently used at a number of operations in North America. The process relies on the greater solubility at elevated temperatures in brine of sylvite in comparison to salt (NaCl).

  • Whether to co-process alternative fuels in cement kilns can be evaluated upon environmental and economic criteria. As is discussed in detail below, the potential benefits of burning alternative fuels at cement plants are numerous. However, the contrary is possible, when poor planning results in projects where cement kilns have higher emissions, or where alternative fuels are not put to their highest value use. Five guiding principles outlined by the German development agency, GTZ, and Holcim Group Support Ltd.

  • Our aim is to minimise the harm caused by flooding. This involves reducing the likelihood of flooding and reducing the impacts when flooding occurs. At the same time there are underlying pressures that are increasing risk, such as climate change, housing development or changes in land use. Sometimes we can affect these drivers, for example by influencing planning and land development. There are, however, other drivers that are beyond our direct influence, such as climate change impacts on the weather and sea level rise.

  • Someone with a prolonged physical illness, a disability or a cognitive impairment (such as Alzheimer’s disease) often needs long-term care. Many different services help people with chronic conditions overcome limitations that keep them from being independent. Long-term care is different from traditional medical care. Long-term care helps one live as he or she is now; it may not help to improve or correct medical problems.

  • It is estimated that approximately one-third of the world’s population are using groundwater for drinking purposes. Pollution of ground water due to industrial effluents is a major issue (Vasanthavigar et al., 2011). Poor groundwater quality brings negative impact to human health and plant growth. In developing countries like India, it is estimated that around 80% of all diseases are directly related to poor drinking water quality and unhygienic conditions (Olajire & Imeokparia, 2001; Vasanthavigar et al., 2011).

  • Other methods have proposed the use of standard beads (Polysciences latex beads), as well described by Gasol and del Giorgio in 2000. Briefly, the beads have to be counted every day and must be sonicated to avoid aggregation. Flow rate calibration can be performed by weighing a tube containing water, processing various volumes, estimating the time needed for each volume to go through and then reweighing the tube. This makes it possible to calculate the mean of the flow rate per minute (Paul, 2001).

  • To avoid headaches and tap into a wider pool of prospective tenants, many landlords consider the lease-purchase of their home. This option attracts many potential buyers who could handle the monthly mortgage payments but can’t afford the required down payment. Here’s how it works: You lease your house to the tenant for a specific monthly rent. In addition, the tenant pays you for the right to purchase the home within the option period, usually six months to two years later. This payment is called the option consideration. The option consideration payment is usually made up of two parts.

  • The central panel of the northern and southern walls contained a quadrant painted with xenia, while the wall of the ground floor, or west, was an image of the river Sarno as penates placed between two festoons of flowers. The image was described as a bearded god wearing a crown of reeds. He was sitting on the ground under the shade of a sacred tree. Resting on his left elbow on an overturned urn, he held a reed in his left hand, and his right hand rested on the corresponding knee. He was nude from the upper part of his...

  • It has been called an audit because it is an attempt, the first as far as we are aware, to take stock: to pull together in one place, from the bewildering variety of sources that provide such information, all the available data on cultural infrastructure and consumption. It systematically attempts to make this data robust: to verify it, ensure as far as possible that it is not partial or selective, and quantify it in such a way that it allows London to be compared with other cities. To assist judgement, we have also recorded, as far as possible on a...

  • The objective of seismic design force of 400, 450 and 550 gal 0.16, 0.50 and 0.84 fractile hazard corresponding curves. It was confirmed that, even with the same model structure and objectives seismic design forces vary with differences in the probability of occurrence of earthquakes. The relationship between total costs and seismic forces in the 0.50 and 0.85 fractile hazard curves, the total cost at 750 gal locally low. This is because the seismic risk is very high at 650 and 700 gal.

  • Scrum is an iterative, incremental framework. Scrum structures product development in cycles of work called Sprints, iterations of work which are typically 1-4 weeks in length, and which take place one after the other. The Sprints are of fixed duration – they end on a specific date whether the work has been completed or not, and are never extended. At the beginning of each Sprint, a cross-functional team selects items from a prioritized list of requirements, and commits to complete them by the end of the Sprint; during the Sprint, the deliverable does not change.

  • As discussed earlier, the idea that human experience involves elements beyond our intentional control has been an overshadowed perspective in philosophy, psychology, and Western culture. Of the diverse perspectives within this tradition, Dewey’s aesthetic philosophy, as expressed in “Art as Experience,” is useful for developing the idea that worthwhile experi- ences require more than just control and rationality. For Dewey, there must be receptive undergoing in addition to active doing and thinking. ...

  • We said that you should be ready to work. Here it is where you should be ready to work. Homework assignments (also known as problem sets) are designed to test your endurance and ability to work under pressure. And you’ll be under a lot of continuous pressure!

  • The Heart Truth warns women about heart disease and encourages them to take action against its risk factors. The message is paired with an arresting image—the Red Dress—the national symbol for women and heart disease awareness. The symbol links a woman’s focus on her “outer self” to the need to also focus on her “inner self,” especially her heart health. The Red Dress is a visual “red alert” to convey the message that “Heart Disease Doesn’t Care What You Wear—It’s the #1 Killer of Women.”...
