Improved Wear Resistance with Copper Tungsten

2013/4/4The structural integrity of copper makes it highly resistant to DC arcing in poor flushing conditions, allowing it to still produce very fine surface finishes. So, for smoother burning and better surface finish, electrode material compositions can include more copper.

5 Global Issues to Watch in 2020

2020/1/8We will also see challenges in specific pockets in middle income countries and growing economies. And that is just the data we know. Poverty data for most of Sub-Saharan Africa, for example, comes from information gathered before the creation of the SDGs five years ago: a reminder that we

Surface area to volume ratio

2019/11/14The lesson finishes by explaining how larger organisms, like humans, have adapted in order to increase the surface area at important exchange surfaces in their bodies. There are regular progress checks throughout the lesson to allow the students to check on their understanding.

Water Distribution System Challenges And Solutions

This is clearly not enough since 90% of the leaks are usually not visible on the surface. This means it takes far too long, often many years, until the utility is even aware that there is a leak. Since awareness time largely determines the volume of water lost from a pipe burst, utilities need a

A Guide to Understanding the Tolerances of Your 3D

Quality vertical surface finishes are a direct result of layer height, nozzle diameter and perimeter extrusion speeds. Increasing the number of perimeter layers would probably not affect the surface finish in the z-direction, but printer extrusion speed and layer height should be adjusted for the best finish.

Quality problems in milling

There are numerous factors that determine the final quality of rice produced by the rice mill. These factors relate to what extent the rice is milled (i.e. low milling degree), the level of grain breakage, level of impurities, color, and presence of off-type kernels such as

Measuring Moisture Content Water Activity

Measuring Water Activity We can't insert a probe into a sample to directly measure its water activity. Instead, water activity is measured by placing the sample into a closed chamber and equilibrating the liquid-phase water in the sample with the vapor-phase water in the headspace and measuring the relative humidity of the headspace.

Measurement of Effects of Erosion and Corrosion

Measurement Challenges When evaluating the effects of erosion and corrosion on a wide variety of substrates, the primary objective is to non-destructively measure the remaining thickness of the substrate. Dependent on the application (i.e. size of the area to

Getting Carried Away: Measuring Soil Erosion

Abstract When you think of environmental challenges facing the world, the first things that come to mind might be global warming, or loss of biodiversity, since these are often in the newspapers. A serious problem that you may not have heard about is soil erosion.

Top 10 Challenges in Oil and Gas Industry

The challenges for this industry come at the same time with some fantastic opportunities emerging for the sector. In the issue of Petroleum Review, February 2012, the Energy Institute listed the top 10 opportunities for oil and gas industry in 2012.

The Raw Truth on Global Temperature Records

2021/4/29From the 1930s to around 1990, scientists measured sea surface temperatures by measuring the temperature of ocean water piped in to cool ship engines. Credit: Robin Matthews / CC BY 4.0 Then, beginning around 1990, measurements from thousands of floating buoys began replacing ship-based measurements as the commonly accepted standard.

Surface Roughness Chart: Understanding Surface Finish in

Surface Roughness Chart The surface roughness chart is a reference material. Manufacturers use it as part of quality assurance processes. As a result, the machining surface finish chart offers important guidelines for measuring standard surface finish parameters.

Drought

Surface Water Careful observation and analysis of the movement and condition of surface water is essential for understanding this resource, especially during times of drought. The California Water Science Center uses a network of more than 500 streamgages to collect real-time data on surface water at locations across the state.

Engine Cylinder Bore Surface Finishes

What's the best type of cylinder bore finish for today's engines? Most would say it's a finish that allows the rings to seat quickly and completely so the engine doesn't use oil. For many applications, that may mean a plateau finish. The surface finish must also meet

Milling Finish: Complete Guide [ Tips, Techniques, and

– One of the challenges for surface finish when face milling is that each insert differs in cut depth by just a little bit–they're not all cutting at exactly the same depth. More expensive facemills let you adjust each insert individually. If you can get them adjusted to a

The influence of , handedness, and washing on the

Bacteria thrive on and within the human body. One of the largest human-associated microbial habitats is the skin surface, which harbors large numbers of bacteria that can have important effects on health. We examined the palmar surfaces of the dominant and nondominant hands of 51 healthy young adult volunteers to characterize bacterial diversity on hands and to assess its variability within

The past, present and future of enzyme measurements

The ability to accurately and sensitively measure the activity of specific enzymes is central to many aspects of modern chemistry and when combined with new nanoscience based approaches, offers significant opportunities for advancing other scientific disciplines.

Ten Questions About Chatter

It might also be addressed by using a cutter design with variable edge spacing, so that waves in the surface don't appear at such regular intervals. However, on a spindle that has a maximum speed of 10,000 rpm or more, the potentially more effective solution becomes possible.
