Why Ethanol is a Fantastic Fuel and Source of Energy

As the modern world moves towards a renewable energy future, ethanol fuel is becoming more popular. And even though it’s not perfect, it presents a sustainable future that doesn’t cause pollution. So, here is a look at why ethanol fuel is the big focal point all over the world. Ethanol Fuel Is More Affordable Given the fact that almost every country is in a position to make their own ethanol fuel, it makes it the most affordable energy source. Basically, if a country can grow sugar cane, corn, or grains, they can start producing ethanol. And when you compare it to conventional fossil fuel, which places huge pressure on developing countries as well as those that produce it, ethanol is the logical next step. In fact, it is a clean energy source that can help to build struggling economies. According to Wall Fireplace Pros, this has led to a significant…

Despite Advances, Effective Wastewater Treatment Remains Challenging

Wastewater originates from two main sources: domestic, and industrial use. Regardless of its source, wastewater must be treated to reduce and remove contaminants and lower the risk of harm to humans, animals and the environment at large. Wastewater Created by Domestic Use Blackwater and graywater are types of sewage, or wastewater, created by domestic and natural processes. Blackwater is contaminated with concentrations of raw fecal matter and other organic contaminants, such as uric acid. It is typically created through the use of flushed-water toilets. Graywater is simply all of the other water that is used domestically. It can become contaminated as the result of direct human activity, such as washing clothes and dishes. Natural processes, such as the run off from storms, can introduce contaminants like silt and other debris into the domestic water supply.

The Latest Gadgets That Bring Peace and Nostalgia

Technology is such a wonderful tool. We use it to create all sorts of gadgets that help us in our everyday lives, make our lives simpler, and allow us to have a bit of fun at the same time. Because the technology changes so frequently, we see items roll out and then shortly after being updated and improved. In some cases, the improvements result in finding ways to create brand new items that add to our day to day lives. Here are some of the latest items that you will want to add to your collection.

The importance of statistical tests – statistical significance and confidence interval

When you start doing more serious research you will need to conduct a statistical test. It helps you to determine weather you hypothesis is significant or can be rejected. If you start browsing for statistical tests online, you will find a large number of possible test that can be chosen depending on you task. In this post lets focus on simple example of statistical test that would let us understand what is statistical significance and what is confidence interval. Building a test scenario In order to understand the matter lets use some random data which is distributed normally. For this we can use 100 hypothetical observations of price tag for new Nokia 3310 from different sources. The average of price is around 50€ with standard deviation of 10€ Now lets plot how those samples are distributed along with normal distribution graph:

New way of using Electrical impedance tomography allows visualizing lung function with high accuracy

Electrial Impedance Tomography (EIT) has been known and studied since early 1980s. Multiple research groups have been working on various applications including monitoring of gastric emptying, lung monitoring, lung perfusion, cardiac and neurological function. Despite the big potential of EIT technology, it still hasn’t been implemented in normal clinical practice. It appears that other methods like CT and MRI are dominant. But CT is dangerous procedure especially if there is a need for constant monitoring. MRI in other hand is expensive and not always accessible. Implementing EIT measurement is really complex due to body bioelectrical properties and small signals reaching 100µV meaning that different impedance distributions can generate same results. A decade ago, technology has been improved that allows building better EIT devices that could allow monitoring patients in the intensive care unit without side effects. Recent breakthrough was made by TU Wien, the Medical University of Vienna and the…

Guide to Linear Servo Actuators

Introduction Servo actuators are used to create motion in specific ways – accurately, they provide motion based on the remote or automatic feedback which tells them when and where and in which direction the movement is supposed to happen. This contrast with the conventional linear motion systems in that they only have one single input to direct their very limited working spheres. Using a servo actuator is something which gives the user a huge advantage when it comes to accuracy and delicacy, both of which are made possible by the controller which is part of every servo, and which compares all the results with the intended results during every motion, so as to be able to correct the motion if there is any discrepancy between the two. Any differences will therefore be changed by the controller. These types of actuators are used in a number of different areas and different…
