In repairing the dash pad, once you remove the dash pad it rips the metal clip off, where it is connected to the car. You can do this by using a j-b weld solution. After you mix the j-b weld, apply it to the broken stub and place the metal clip, with the ripped plastic, correctly on top of the j-b weld. Then wait until it dries.

The common thread between this week's Brief Reality stories is that augmented reality is beginning to prove its worth as a technology that improves workflows and processes. From customer service to healthcare to manufacturing, augmented reality is helping companies improve productivity.
Call it OCD if you will, but I make it a priority to have a clean Notification panel. Like a chalkboard that isn't wiped spotless, I get an unsettling feeling that something in the universe isn't complete when there's unnecessary clutter in the drop-down. For this reason, I loathe the fact that I can't remove the "Wi-Fi connected" tile from my "Notifications."
Hydrogen can be used to improve mileage. The hope with this method is that hydrogen will increase the amount of gasoline combusted and increase fuel efficiency, as you trickle hydrogen into the tank. Often propane is used to increase gas mileage. The studies are still being done. There's no official data at present, but there is significant experimentation.
In this video, we practice describing solutions in English. For example, if the problem is that you have stomach problems, the solution is that you should go to the doctor. Should simply means a good idea or a recommendation. You could also say the solution is that you need to go to a doctor. For the next example, if your problem is that your car won't start, this means your car will not start. You could also say that your car does not start, which is a good way to describe the problem. For t...

The Department of Biological Sciences at the University of Alberta brings you this video tutorial specifically relevant to your student laboratory courses, specifically microbiology. If you're a student at any school of biology, this information will be helpful for learning how to mix gradients with a gradient mixer in the lab.
Solving 6 math problems using different methods is the idea behind this video. First, you make three rows of numbers vertically from 1-9. All the numbers match across for example, 1 1 1, 2 2 2, 3 3 3, and so on. Each set of numbers creates a mathematical problem who's solution is the number six. These problems require some thinking to solve. The only one that is immediately apparent is 2 2 2=6 which is, of course, 2+2+2=6, (3x3)-3=6, the square root of 4 =2. This done on all three of the four...

Rust protection doesn't have to cost a fortune. With a little zinc and some electricity, you can protect your precious metals from rust by galvanization. When you galvanize something, you're giving it a protective coating, and in this case, it's a zinc coating.
Redneck Productions teaches viewers how to clean silver and coins. This shows you how to clean coins with electricity! This process is good because you do not have to rub or scratch your coins and silver in the process. First you will need to get a battery (AA) and wire. Connect the battery and wire with the wire connected to each side of the battery. Next, you will need to get a plastic Tupperware dish. In this dish mix the solution of equal parts baking soda and Iodized salt and mix this in...
Given a equation of a line, you can graph the line. A system of equations is nothing but equations of more than one line. In a single equation all the points that lie on the line, satisfy the equation of the line. Similarly a solution of a system of equations is points that satisfy each and every equation of that system. A system of equations can have a single point as solution when the lines intersect at a common point, or have a unlimited points in solution when the lines overlap on each ot...
A method for solving a linear system with no solution is described. The method is described in 4 steps. The first step in the method is designed to solve a linear system that is described consist of “solving by graphing”. Details for “solving by graphing” first consist of finding points to graph using two different equations. The second step in the method consist of placing the points from both equations on the same graph in order to find out if bo...

After stealing the show at the HoloLens 2 launch and starring in Qualcomm's unveiling the Snapdragon XR2, holographic video conferencing app Spatial has landed a leading role in Magic Leap's second act with the enterprise segment.
In this video the instructor shows how to solve a system of equations by elimination method. First you need to know how many possible number of solutions you can get by solving a system of equations. There are three possibilities. In the first case there are two lines with different slopes, so they intersect at a point which is the solution to that system. In second case there can be two lines with same slope but are parallel to each other. In this case the system has no solution. In the thir...

Welcome back, my greenhorn hackers! Continuing with my Wi-Fi hacking series, this article will focus on creating an invisible rogue access point, which is an access point that's not authorized by the information technology staff and may be a significant security vulnerability for any particular firm.
Want to test whether the soil sample or a water sample contains boron, watch this video. As shown in the video, the first step is to create test specimens of various concentrations using a simple turmeric and ethanol solution as a base for comparison. The basis of this experiment is the fact that curumin present in turmeric reacts with boron to form a reddish compound and so the result of this reaction can easily be verified visually.

Hacking Wi-Fi is a lot easier than most people think, but the ways of doing so are clustered around a few common techniques most hackers use. With a few simple actions, the average user can go a long way toward defending against the five most common methods of Wi-Fi hacking, which include password cracking, social engineering, WPS attacks, remote access, and rogue access points.
Leaving your Wi-Fi radio "on" allows your smartphone to auto-connect to trusted wireless networks in lieu of using cellular data, but it also consumes battery power while it's constantly network hunting.
