Wordology, Ambulance

The word 'ambulance' derives from the Latin 'ambulare', meaning 'to walk or move about'. This gave rise to the French hôpital (sic) ambulant, meaning mobile hospital. It used to refer to a temporary medical structure that could be easily moved, such as movable army medical hospitals. In English, ambulance first appeared around 1798 and also referred to temporary hospital structures.

Ambulances were first used for emergency transport in 1487 by the Spanish, and civilian variants were put into operation in the 1830s. Mobile medical transport vehicles were also called ambulances in French and were designed to get injured soldiers off the battlefield and to medical aid during battle. One of the first instances of this was during the Crimean War. During the American Civil War they were known as ambulance wagons.

The first known hospital-based ambulance service was based out of Commercial Hospital, Cincinnati, Ohio, US, in 1865.

National Hobo Convention

For some odd reason, the ambulance reminded me that beginning this week, August 7-10-2014 is the National Hobo Convention in Britt, Iowa (close to Mason City and Clear Lake). There is a parade on Saturday at 10:00 a.m.  "Some in rags, some in tags, some in velvet gowns."

Hobos are migratory workers, some with a special skill or trade, others ready to work at any task, but always willing to work to make his way. The tramp is a traveling non-worker, moving from town to town, but never willing to work for the handouts he begs for. A bum is the lowest class, too lazy to roam around and never works.

There will be marching bands, queens, business floats, children, adults, and hobos all come down the streets in one long line and share the fun that only a Hobo Convention can provide. Following the parade, mulligan stew is available. Other events during the weekend include a 5K & 10K Walk/Run, Hobo King & Queen coronation, Hobo Museum, Hobo Auction, Hobo Memorial Service, Vagabond Craft show, and Outdoor Classic Car Show.

Stores Meet Iternet

Home improvement giant Lowe’s just bought 42,000 handheld point of sales devices for its 1700+ outlets. Its competitor Home Depot spent $64 million placing 30,000+ of its First Phone Motorola mobile devices. Nordstroms has 6,000 devices. Urban Outfitters and Pacific Sun are following. Mobile and tablet technology is changing the way we shop.

Smaller businesses use Square, a free tiny box like card reader that plugs into smart phones or pads to transform them into registers on the go. In fact, there are a host of other companies offering ways for stores and vendors to capture sales without using a cash register. Great for those who have small stores or do kiosk type shows to now accept credit cards and sales with little expense and no hassle.

Major chains like Whole Foods Market, Gap, Patagonia, Sears, and Kmart are now using mobile devices to email receipts to customers instead of handing them paper. Of course, they are also tacking on email alerts and advertisements, which may explain why only about one third of customers are opting in. Customers can now try and buy in the store and have stuff shipped home for free. Better than lugging it around the mall as they continue shopping.

Amazing how, in a few generations telephones, cash registers, typewriters, incandescent light bulbs, etc., once revolutionary, have already become obsolete. For techies in the crowd, the Singularity has begun.

High Tech Meets Low Tech

An inexpensive diagnostic test made from paper has been developed that can assess liver health in 15 minutes and for only pennies a test. The test uses a single drop of blood from a finger prick to measure the presence of liver enzymes, and doesn't require the presence of a laboratory, instruments, or syringes. If liver enzymes are present in the blood, wells within the paper will show a color change, which are be color matched to a scale to determine approximate degree of concentration. A color change indicates the concentration range of enzymes present. Though this can be checked by eye, greater accuracy could be achieved by scanning the paper with a smartphone, which are incredibly prevalent throughout regions in which the kit would be used.

Liver damage can be a consequence of taking antiretroviral drugs, which are prescribed to HIV patients. Because of the high HIV infection rates in poor countries, liver problems are on the rise, so the ability to cheaply monitor blood is important to prevent potentially fatal side effects of the drugs meant to save people’s lives.

The paper uses patterns, channels, and assay zones (or wells) of water-repellent materials on a piece of paper about the size of a postage stamp. Biological and chemical assay reagents are then deposited in the wells. When blood, urine, saliva, sweat or other biological samples are applied to it, the paper wicks the sample through the channels to the assay zones, without external pumps or power. Upon contact, the assay zone quickly changes color and results are then easily read by comparing the color change with a printed reference scale. After use, it can be easily disposed of by burning.

These patterned paper-based devices can be embedded with electrical circuitry to enable resistive heating, electrochemical assays, or initial processing of assay results. Multiple sheets of patterned paper can be stacked to generate three-dimensional devices capable of automatically performing a variety of complex fluid operations such as splitting, filtration, mixing, and separations.

The postage stamp-sized paper diagnostics system was developed in the laboratory of Harvard Professor George Whitesides seven years ago. With funding from the Bill and Melinda Gates Foundation, Professor Whitesides started the non-profit organization, Diagnostics For All., and looked to improve the health of the poorest areas of the world. The team is also working on malaria and dengue fever tests.

An ink jet printer using wax ink prints a pattern on two sheets of paper. One sheet contains reagents that react with liver enzymes, the other dyes that change color if a reaction occurs. The two sheets are fused together by heating, so that channels or wells that can be used as miniaturized test tubes for reactions are produced. A plasma filter is added and the three are laminated together, and cut into postage stamp size squares. The rest of the world could also benefit from this low cost efficient healthcare.

Toilet Paper Origami

Speaking of low tech, I was floored when I came across a site on Pinterest that is dedicated to making origami figures from toilet paper. It has everything from flowers to boats, and more. Almost was afraid to share this, but couldn't help myself. If you really want to waste some time, here is the LINK.

Email and Productivity

If you want to be efficient, do not open your email until at least 10am. Do not peek. Do not IM. Do not check Facebook, Google+, LinkedIn, or Twitter, or anyplace else on the web.

Productive people get up and get on with doing the things they have decided are important. Reacting to someone else is not productive, nor is it efficient or effective. It is difficult to read an email without reacting and you are reacting to someone's priority, not yours.

Next, decide the clock time and a certain amount of action time to read and react to email. Quickly scan your inbox and prioritize, file, or delete as necessary. This should take no longer than ten minutes. Then go back and react to the priority items and attack them. When one hour has elapsed, go back to your priorities.

You might need to get into your email to finish some of your most important to-dos, but can you get 80 or 90 percent done before you go into email and waste your time on other people's priorities

Research shows email: Creates stress, can be more addictive than alcohol and tobacco, and checking email frequently is the equivalent of dropping your IQ ten points. It also interrupts your progress. Happiness is also important, so after you have finished your high priority projects, reward yourself by reading my Friday Thoughts.

Real Credit Score Report

Finally, here is a site that provides your actual credit score for free. That is no credit card info required to sign up. No fees. It does ask to link your cards and offers other add ons for fees, but you can get the basic info, including your credit score for free. There are free credit reports from each of the big three, transunion, etc., but they only give transaction info once each six months, and do not provide the credit score.

I never could understand how companies could take my information from wherever they choose, then try to sell that information about me to me. This one is different. CreditKarma.com.

Uses for Aloe Vera

A friend recently dropped off some Aloe Vera for the garden. I knew it had some great medicinal properties, but found more on the web. Also found it survives the winter in Texas. It is antibacterial and contains vitamins and minerals. Here are a few topical and other uses.

• Slice aloe leaves lengthwise and use the inner sides as a biodegradable body scrub in the shower
• Rub on to treat burns from grease splatters or hot utensils
• Rub on to reduce sunburn sting
  
• Rub on to eliminate sting or itch from insect bites and allergic skin reactions
• Rub on to fight Athlete's Foot
• Rub on as moisturizer for dry skin, remove makeup, or for shaving
  
• Soothe Psoriasis, Rosacea, Eczema, blisters, bruises, and rashes
  
• Prevent scarring and stretch marks
• Reduce facial wrinkles
• After washing, apply to eliminate acne
  
• Decrease skin pigmentation and dark spots
• Drink to relieve indigestion, but not too much or can cause diarrhea
  
• Take aloe orally to relieve heartburn, arthritis, and rheumatism pain
• Boil leaves in a pan of water and breathe in the vapor to reduce affects of asthma

Friday Thought

Happy Friday

Laughter is the only music with no sour notes.

Music is like smiling out loud while enjoying a Happy Friday!

Placebo and Color Affect

Researchers found the color of a package and a pill makes a difference in how it works. In one study, every patient was given the exact same sedative, but some patients received it in a blue pill and others in an orange pill. The blue pill takers reported falling asleep 30 minutes faster, and sleeping 30 minutes longer, than the orange pill takers.

You likely know that you can give a person with a headache a Tic Tac, say it is medicine, and it may eliminate a headache just like an aspirin would, for reasons science doesn't completely understand. This phenomenon is also affected by color. In other words, how you perceive effectiveness affects effectiveness and color matters.

Subjects, in another study were told they would get a sedative or a stimulant, when they were actually getting placebos. Sixty six percent of the subjects who took blue pills reported feeling less alert, compared to only twenty six percent of those who took pink pills. It is because we have been conditioned to think that blue is tranquil.

In yet another study, when researchers put various fake medicine packages in front of subjects, the subjects picked certain colors of boxes over others. Warm colors like brown and red were perceived as more potent, especially if the shades were darker. This is why heart medicines are often red and brown, while skin medicines are yellow, and sleeping pills are often blue. Painkillers are most often white. All carefully chosen to match our perceptions.

The majority of fast food chains have red and yellow or orange in their logo, because these are stimulating colors. Lowfat containers, more often than not have blue on the package.

Color associations are also cultural. In America blue is a calming and peaceful color, but in Italy it is associated with the national soccer team. Researchers found that, rather than making him drowsy, a blue pill might send an Italian singing into the night.
