Geophysical Technology – Ground Penetrating Radar Survey

Ground penetrating radar survey is a non-invasive geophysical technology that allows archaeologists and other historical research teams to gather information about what’s below ground without disturbing the surface. The technique uses electromagnetic pulses that reflect off subsurface features in the ground and are picked up by a receiver antenna. By measuring the strength and time delay of these responses it’s possible to estimate their depth. By collecting this data across an entire area, it’s also possible to map below ground features and create a 3D image of the underground environment.

As the electromagnetic signals travel through the ground they hit interfaces with different electrical conductivities and dielectric constants. This results in a portion of the signal reflecting off each interface and passing through to the next interface. Each reflected signal changes the polarity of the radar waves and is recorded as a different color on the radar profile, representing different voltage peaks. The resulting information can then be displayed in various formats – such as radar profiles, plan view maps isolating specific depths or three-dimensional models.

Advantages of Utilizing GPR Surveys in Various Applications

The penetration depth of a GPR investigation is dependent upon the frequency of the antenna, soil conditions and moisture content. High frequencies provide greater resolution but do not penetrate as far as lower frequencies.

With proper training, geophysical technicians can interpret GPR data and identify buried pipe and other underground features. GPR can locate metallic and non-metallic objects, voids and construction layer interfaces. It can also estimate the dimensions of larger objects and their depth. This allows the technician to quickly scan a site for utilities, voids and other obstructions in a non-intrusive, non-destructive manner.…

The Best Cold Press Juicer

best cold press juicer

While best cold press juicers is not for everyone, many people find that it’s a good way to get more servings of fruits and vegetables into their diet. Whether you want to make juice for one or the whole family, our top-rated cold press juicer can help you do it. This model extracts significantly more antioxidants, live enzymes, and vitamins than typical centrifugal models, plus it’s quiet and easy to clean.

It’s not cheap, but it is well-made and a great option for those who will be using it regularly. It has a large chute that fits whole produce, so you don’t need to spend time prepping it, and it blitzes leafy greens and fruit quickly. Plus, every removable part is dishwasher-safe and it has clear marks to make putting it together and using it a breeze.

Longevity and Durability: Investing in a High-Quality Cold Press Juicer

This machine is a bit more expensive than our top pick, but it’s made by a brand that stands for quality and looks lovely on the counter. It also does a great job of juicing leafy greens and wheatgrass, while the wide chute makes it easier to feed whole fruits and vegetables into it. Plus, it has the smallest footprint of any of the machines we tested and is relatively quiet in use.

It’s not as versatile as some of the other models we’ve reviewed, but it does a fantastic job at making juice and can be used to make frozen desserts like sorbet. The design is sleek and elegant, and it’s available in a variety of colors to match any kitchen decor.
