BC Wildfires 2017 – UrbanWorkbench

Mike Thomas Mike Thomas P.Eng. ENV SP, is the author of UrbanWorkbench.com and Director of Engineering at the City of Revelstoke in the Interior of British Columbia, Canada. If I post something here that you find helpful as you navigate the world of engineering, planning and building communities, that’s wonderful. But when push comes to shove: This is my personal blog.

The Earth’s Interior

Our Earth consists of many hidden treasures in its fold, which we need to explore. Much of the current information about earth’s interior comes from studies relating to the paths of earthquake waves travelling through the Earth, and from laboratory experiments on surface minerals and rocks at high pressure and temperature. Other important information comes from geological observations and the flow of heat from inside the earth. Crust- The Earth’s outermost surface is called the crust. The crust is typically…

‘Shape Memory’ Effect Demonstrated in Gold Particles — ScienceDaily

Researchers from the Technion-Israel Institute of Technology and Germany have demonstrated for the first time the phenomena of shape memory and self-healing in gold microparticles. Achieved through defects-mediated diffusion in the particle, the discovery could one day lead to development of micro- and nano-robots capable of self-repair; mechanically stable and damage-tolerant components and devices; and targeted drug delivery. The study, published in the journal Advanced Science, was conducted by doctoral student Oleg Kovalenko and Dr. Leonid Klinger, led by Prof.…

Could concrete help solve the problem of air pollution? — ScienceDaily

New research reveals that sulfur dioxide, a major contributor to air pollution, is removed from the air by concrete surfaces. Stony Brook University researcher Alex Orlov, PhD, and colleagues discovered how concrete interacts and eliminates sulfur and nitrogen oxides. Their findings, published in the July edition of the Journal of Chemical Engineering, could be a significant step toward the practice of using waste concrete to minimize air pollution. According to the World Health Organization, as many as seven million premature…

Diatoms have sex after all, and ammonium puts them in the mood — ScienceDaily

New research shows a species of diatom, a single-celled algae, thought to be asexual does reproduce sexually, and scientists learned it’s a common compound — ammonium — that puts the ubiquitous organism in the mood. The findings, published today in PLOS One, may be a key step toward greater understanding of the evolution of sexual behavior and also have important biotechnology implications. “Our discoveries solve two persistent mysteries that have plagued diatom researchers,” said corresponding author Kimberly Halsey, a microbiologist…

New mass spectrometry for general use — ScienceDaily

Customs officials want to detect contraband. Doctors want to know how quickly a patient is metabolizing a therapeutic drug. And suppliers of organic products, from nutritional supplements to honey, want to know their raw materials are pure. Each case calls for mass spectrometry — a technique that identifies molecules based on their mass — but current instruments are bulky, expensive, and typically specialize in one class of chemicals, discouraging widespread use outside of a specialized lab setting. Mass spectrometry is…

No Billing Postal Code? No Problem! – Square Corner Blog – Medium

How To Remove the Postal Code Field (Square Payment Form) As Square’s eCommerce platform expands outside the United States and Canada, we’ve heard feedback from developers in other countries (e.g. Japan & Australia), where requesting billing postal codes is uncommon, that they’d like to remove the postal code field in their eCommerce Payment Form. Good news! Effective today, to remove the postal code field, all you need to do is change one line of code. When you load the eCommerce Payment…

How to make ‘your own supernova’ — ScienceDaily

One of the most extreme astrophysical events, Supernova explosions are the violent deaths of certain stars that scatter elements heavier than hydrogen and helium into surrounding space. Our own solar system is thought to have formed when a nearby supernova exploded distributing these elements into a cloud of hydrogen that then condensed to form our sun and the planets. In fact, the very atoms that make up our bodies were formed in the remnants of such an explosion. Working in…

Introducing ELF: An extensive, lightweight and flexible platform for game research | Engineering Blog | Facebook Code

Games provide a useful environment for artificial intelligence research. Within a game environment, the amount of labeled training data available for training AI models is nearly infinite, low-cost, replicable, and more easily obtained at a much higher rate than in real-world experiments. These attributes are helping facilitate research underway in Facebook’s AI Research lab (FAIR) to explore both short-term milestones like demonstrating the strength of AI in multiple complicated game environments, and long-term goals aimed at applying AI to real-world…

How to make your site HTTPS-only

The Internet is getting more secure every day as people enable HTTPS, the secure version of HTTP, on their sites and services. Last year, Mozilla reported that the percentage of requests made by Firefox using encrypted HTTPS passed 50% for the first time. HTTPS has numerous benefits that are not available over unencrypted HTTP, including improved performance with HTTP/2, SEO benefits for search engines like Google and the reassuring lock icon in the address bar. So how do you add…
