It’s a frustrating fact that whenever you try to improve materials like steel, you end up introducing new weaknesses at the same time. It’s a balancing act between different properties. Now, engineers have developed a new type of “super steel” that defies this trade-off, staying strong while still resisting fractures.

For materials like steel, there are three main properties that need to be balanced – strength, toughness and ductility. The first two might sound like the same thing, but there’s an important difference. Strength describes how much of a load a material can take before it deforms or fails, measured in Pascals of pressure. Toughness, meanwhile, measures how much energy it takes to fracture a material.

For reference, glass has relatively high strength but low toughness, so it’s able to support quite a bit of weight but it doesn’t take much energy to break.

The C20 will replace the C8 as the personal defence weapon for Canadian Forces sniper teams, confirmed Department of National Defence spokeswoman Andrée-Anne Poulin.

The government will also launch a competition sometime this month to buy 229 bolt action sniper rifles. That rifle, designated as the C21, will be used for long-range shooting and will come in two different calibres.

The Canadian Forces says the new C20, which will be in 7.62 calibre, will be more accurate and an improvement over the current C8 used by sniper teams.

Masks, gowns, and other personal protective equipment (PPE) are essential for protecting healthcare workers. However, the textiles and materials used in such items can absorb and carry viruses and bacteria, inadvertently spreading the disease the wearer sought to contain.

When the coronavirus spread amongst healthcare professionals and left PPE in short supply, finding a way to provide better protection while allowing for the safe reuse of these items became paramount.

Research from the LAMP Lab at the University of Pittsburgh Swanson School of Engineering may have a solution. The lab has created a textile coating that can not only repel liquids like blood and saliva but can also prevent viruses from adhering to the surface. The work was recently published in the journal ACS Applied Materials and Interfaces.

On April 7, Karin Shetler awoke in the middle of the night to a toe that was throbbing violently. She threw back the covers to reveal her purple-colored middle toe.

“I wondered whether I had somehow broken my toe,” said Shetler. “I iced it, not understanding what it was, and called my physician sister in New Orleans the next morning.”

She asked if it might be gout. It wasn’t.

Hypothetical COVID-19 Treatments.

The virus causes clotting everywhere and widespread epithelial damage. One is tempted to treat it like stroke prophylaxis. Patients clot rather than bleed, almost always. The same thing happens in influenza, also.

The pro-clotting effects of corticosteroids may be a reason why they have not stood out yet. The profound anticlotting treatment necessary to treat patients with ECMO extracorporial oxygenation in COVID-19, might have its own therapeutic value (it’s not just the artificial lung but the heparin they need to put you on it!). The lungs of COVID-19 patients in trouble are not only full of fluid, but macro and micro-emboli. Low molecular weight heparin, given in all ICUs, looks like a good gamble.

System could be scaled-up to supply clean and renewable energy.

A research team including Kanazawa University tests the impact response of the world’s hardest concrete.

Concrete is the most widely used building material in the world and consequently is being continuously developed to fulfill modern-day requirements. Efforts to improve concrete strength have led to reports of porosity-free concrete (PFC), the hardest concrete tested to date. Some of the basic properties of PFC have already been explored, and now a team including Kanazawa University has probed the impact response of this innovative material. Their findings are published in International Journal of Civil Engineering.

Ultra-high-strength concrete offers significant advantages including reducing the weight of large structures and protecting them against natural disasters and accidental impacts. PFC is an ultra-high-strength concrete whose properties can be further enhanced by incorporating steel fibers.

We propose to study the implementation of an innovative thrust producing technology for use in NASA missions involving in space main propulsion. Mach Effect Gravity Assist (MEGA) drive propulsion is based on peer-reviewed, technically credible physics. Mach effects are transient variations in the rest masses of objects that simultaneously experience accelerations and internal energy changes. They are predicted by standard physics where Mach’s principle applies as discussed in peer- reviewed papers spanning 20 years and a recent book, Making Starships and Stargates: the Science of Interstellar Transport and Absurdly Benign Wormholes published in 2013 by Springer-Verlag.

In Phase I we achieved the following:
