Within the academic aviation world, good textbooks can be hard to come by. Not only do few aviation textbook publishers exist, but the aviation industry is constantly changing. The TRB Airport Cooperative Research Program's latest Impacts on Practice brief, ACRP in the Classroom: Reimagining the Textbook at the University of North Dakota Department of Aviation , details how Dr. Kim Kenville uses ACRP Research Report 16, Second Edition: Guidebook for Managing Small Airports , in her classes. “This publica...

V pražských Košířích má svou ulici. Národní umělec Vítězslav Vejražka  (1915–1973). Články, které se čas od času objeví, zdůrazňují jeho mužnost. „Prostě chlapák,“ tak pojmenoval svůj medailón Týdeník Televize. Ve skutečnosti byl Vítězslav Vejražka placenou štětkou Státní bezpečnosti a na rozkaz se vyspal s každým, koho mu tajná policie předhodila. Včetně vlastní tety. Přečtěte si bizarní příběh herce, který by dnes slavil 105. narozeniny.

Find Local Classifieds browser hijacker removal instructions

What is Find Local Classifieds?

Find Local Classifieds browser hijacker is designed to promote the findlocalclassifiedstab.com address, a fake search engine. Like most apps of this type, it promotes it by changing certain browser's settings. Usually, browser hijackers not only modify settings but also collect various (mostly browsing-related) information. Since users often download and install apps like Find Local Classifieds unintentionally, unknowingly, they are categorized as potentially unwanted applications (PUAs).

Since the outbreak of COVID-19, face masks have been in high demand. One company decided to take an eco-friendly approach to manufacturing and supplying the public with protective masks. The Professional Association of Diving Instructors (PADI) partnered with the sustainable sportswear company Rash’r to turn plastic pollution found in the ocean into face masks.

All proceeds from the masks go directly back into the manufacturing of more masks to help recycle plastics from the ocean. The masks feature a number of ocean-themed designs and include special sizes for kids. The company has received more than 15,000 mask pre-orders in just a few weeks—which has helped recycle more than 1,300 pounds (590 kg) of ocean pollution. The U.S. Centers for Disease Control and Prevention (CDC) now recommends that people wear cloth face masks to prevent the spread of COVID-19 in public places. The masks made by PADI offer a sustainable alternative to the N95 respirator masks being reserved for health care workers.

The Society for Laboratory Automation and Screening (SLAS) announced the winners of its annual New Product Awards Monday afternoon at the 9th Annual SLAS International Conference and Exhibition in San Diego, CA, USA.

SLAC scientist Siqi Li works on new methods to allow researchers using LCLS, our X-ray laser, to observe the motion of electrons or do high-resolution imaging. When she's not working to create more efficient and advanced X-ray lasers, Li likes to unwind with yoga.

Regular readers will know that I've been hanging out for the "market allocation" parts of the proposed Cannabis Legalisation and Control Bill, which will be the subject of a referendum this year.
While most media outlets ran inane stories last year on how many joints 14 grams added up to, it was clear to anyone who took the subject seriously that the questions of who would get to produce and sell cannabis and how licences would be awarded were vastly more important. And we've had to wait for answers to those.
Well, they're here. And it's very good news. From…

Enterprise demand set to soften, offset tier-two cloud, telco sales

Global server shipments reached an industry record-breaking 3.3 million units in the first quarter of 2020, marking a 30 per cent year-on-year growth, Omdia analysts estimated this week.…

Nice way to get to Alpha Centauri though boffin tells us: 'Such a laser system could be used as a weapon'

Coin-sized pieces of graphene can be accelerated by firing low-powered lasers at them in micro-gravity conditions, say scientists. The technology could be a stepping stone to graphene solar sails, which could propel future spacecraft using starlight or a laser array.…

I realize that sounds kinda nuts — why are we asking PARENTS to show us their KIDS being independent? Who, after all, is better at making videos? Mom or little Ava (who’s 5)? But legally we can’t ask anyone under 13 to do anything. So go document your children doing something new on their own, […]

The National Highway Traffic Safety Administration (NHTSA) finds Tesla's Autopilot cuts crashes by 40%. How cool is that? Autonomous vehicles are going to cause a huge decline in accidents and deaths. Even short of autonomous vehicles, when you get your next car try to get one that supports automatic braking on imminent collision detection. You could get a large fraction of the collision avoidance benefit at a much lower cost today. Check out Insurance Institute for Highway Safety ratings of collision avoidance systems in current cars. Watch a Tesla react to a crash in front of it: Watch a Tesla avoid hitting a reckless driver: A recent analysis finds that autonomous vehicles will allow 2 million disabled people to get...

Arterial cardiovascular events are the leading cause of death in patients with JAK2V617F myeloproliferative neoplasms (MPNs). However, their mechanisms are poorly understood. The high prevalence of myocardial infarction without significant coronary stenosis or atherosclerosis in patients with MPNs suggests that vascular function is altered. The consequences of JAK2V617F mutation on vascular reactivity are unknown. We observe here increased responses to vasoconstrictors in arteries from Jak2V617F mice resulting from a disturbed endothelial NO pathway and increased endothelial oxidative stress. This response was reproduced in WT mice by circulating microvesicles isolated from patients carrying JAK2V617F and by erythrocyte-derived microvesicles from transgenic mice. Microvesicles of other cellular origins had no effect. This effect was observed ex vivo on isolated aortas, but also in vivo on femoral arteries. Proteomic analysis of microvesicles derived from JAK2V617F erythrocytes identified increased expression of myeloperoxidase as the likely mechanism accounting for their effect. Myeloperoxidase inhibition in microvesicles derived from JAK2V617F erythrocytes suppressed their effect on oxidative stress. Antioxidants such as simvastatin and N-acetyl cysteine improved arterial dysfunction in Jak2V617F mice. In conclusion, JAK2V617F MPNs are characterized by exacerbated vasoconstrictor responses resulting from increased endothelial oxidative stress caused by circulating erythrocyte-derived microvesicles. Simvastatin appears to be a promising therapeutic strategy in this setting.
