Monoculars are available in a variety of sizes and magnifications making them ideal for mid-distance as well as for far-distance viewing. Many with low vision use a monocular to read text on blackboards, whiteboards, and projection screens, as well as to view artwork in museums. How far can you seeRead More →
Conventional wisdom from the 11-a-side game says play on the side of your stronger foot. As most of us know, when it comes to the full game, if you’re left-footed you generally play on the left; if you’re right-footed you typically play on the right. Are left-footed players more oneRead More →
Which Communication Method Is More Secure? While email has been widely embraced in the digital era for its speed and convenience, sending a fax is more secure. Emails pass through digital firewalls, servers, and virus checkers. Thus, they’re copied and can be compromised during the process. What are the advantagesRead More →
No. Ink will dry properly on regular paper. You will find that some cheap papers (not all) will cause “bleed” or “feathering”, so the letters you write will look smeared as they dry. It’s really not a big problem though. What is the difference between a fountain pen and aRead More →
As more people became reliant on cars, roads and highways were soon built to support them. Soon enough, advertisers realized that setting up billboards on roads and highways was an excellent advertising strategy. After the introduction of the Model T, cars quickly became the main form of transportation. What makesRead More →
Deer Seek Windbreaks Naturally, bedding on a south-facing slope helps block some of razor sharp cold and in turn, conserves calories. That aside, regardless of the weather, mature bucks generally prefer to bed on the leeward (downwind) side of a ridge anyway. What is a north Face slope? Basically, aRead More →
An important feature of autocatalysis is the requirement of—at least—a seeding quantity of autocatalyst for the start of the reaction since the state of extinction S0 with x(0) = 0 implies no reaction, v(0) = 0 and ignition of the reaction does not occur. Why are catalyst needed? Catalysts speedRead More →
STP was originally standardized as IEEE 802.1D but the functionality of spanning tree (802.1D), rapid spanning tree (802.1w), and multiple spanning tree (802.1s) has since been incorporated into IEEE 802.1Q-2014. Is Rstp compatible with STP? The ArubaOS implementation of Rapid Spanning Tree Protocol (RSTP) is as specified in 802.1w, withRead More →
One type of balancing selection is the heterozygote advantage. This is when heterozygous individuals have an advantage over homozygous individuals, as is seen with the sickle-cell allele. Why can heterozygote advantage result from directional or stabilizing selection? Stabilizing selection acts against both extreme phenotypes and favors the intermediate phenotypes. …Read More →
Use of gradient elution has several advantages over isocratic elution: (i) it allows the separation of components in the sample that have significantly different affinities toward the surface (e.g., weakly binding proteins eluting early and strongly bind proteins late in the gradient) and (ii) it alleviates the need … WhichRead More →
