Denver Developmental Screening Test Ii Pdf Converter

First you need to make a line from top to bottom of page intersecting the childs age and barrs that it intersects are things that the child should be able to do give or take a little. There are special kits with all the tools and toys needed or you can improvise. Questions marked with a certain letter can simply be answered by the parents others you must see the child do, like feed a doll a bottle etc. It's fairly simple although it usually takes quite a bit of finessing to get children of certain ages to cooperate.

The installed feed capacity of Isasmelt furnaces has grown as the technology has been accepted in smelters around the world. Graph courtesy of Xstrata Technology. ISASMELT technology has been applied to lead, copper, and nickel smelting, and by 2013 fifteen plants were in operation in ten countries, with another five in various stages of development. The installed capacity of the operating plants in 2013 was over 8 million tonnes per year ( t/y) of feed materials, with additional capacity to come on line in 2013 and 2014. Smelters based on the copper ISASMELT process are among the lowest-cost copper smelters in the world. Download game ben 10 omniverse 2 wii.

Mineral concentrates or materials for recycling are dropped into the bath through another hole in the furnace roof or, in some cases, injected down the lance. These feed materials react with the oxygen in the injected gas, resulting in an intensive reaction in a small volume (relative to other smelting technologies). ISASMELT lances contain one or more devices called 'swirlers' that cause the injected gas to spin within the lance, forcing it against the lance wall, cooling it.

They are designed to minimize pressure losses changing the angle from axial to tangential thus creating a strong vortex. The vortex helps mix liquids and solids with oxygen in the bath. The cooling effect results in a layer of slag 'freezing' on the outside of the lance. This layer of solid slag protects the lance from the high temperatures inside the furnace.

The tip of the lance that is submerged in the bath eventually wears out, and the worn lance is easily replaced with a new one when necessary. The worn tips are subsequently cut off and a new tip welded onto the lance body before it is returned to the furnace. ISASMELT furnaces typically operate in the range of 1000–1200 °C, depending on the application. The refractory bricks that form the internal lining of the furnace protect the steel shell from the heat inside the furnace. The products are removed from the furnace through one or more 'tap holes' in a process called 'tapping'. This can be either continuous removal or in batches, with the tap holes being blocked with clay at the end of a tap, and then reopened by drilling or with a thermic lance when it is time for the next tap. The products are allowed to separate in a settling vessel, such as a rotary holding furnace or an electric furnace.

While smelting sulfide concentrates, most of the energy needed to heat and melt the feed materials is derived from the reaction of oxygen with the sulfur and iron in the concentrate. However, a small amount of supplemental energy is required. ISASMELT furnaces can use a variety of fuels, including coal, coke, petroleum coke, oil and natural gas. The solid fuel can be added through the top of the furnace with the other feed materials, or it can be injected down the lance. Liquid and gaseous fuels are injected down the lance.
