How Tuberculosis Spreads

Tuberculosis:  By the Numbers

  • Tuberculosis (TB) is second only to HIV/AIDS as the greatest killer worldwide due to a single infectious agent.
  • About one-third of the world’s population has latent TB, which means people have been infected by TB bacteria but are not (yet) ill with disease and cannot transmit the disease.
  • People infected with TB bacteria have a lifetime risk of falling ill with TB of 10%.
  • Without proper treatment up to two thirds of people ill with TB will die.

Fort Qu'Appelle Sanatorium

Fort Qu’Appelle Sanatorium (Saskatchewan, Canada)

The Saskatchewan Anti-Tuberculosis League

The “Great White Plague” was the name used to describe tuberculosis. To fight the highly contagious disease the Saskatchewan Anti-Tuberculosis League was formed in 1911. Under its auspices Fort Qu’Appelle Sanatorium, pictured above, was opened in 1917 to provide rest and fresh air. But the cure was long and tedious; few could afford to remain until they were healed. So in 1929, through the League’s urging, Saskatchewan was the first province to make the care and treatment of tuberculosis free of charge.

What is in these tablets?

Amphetamines (methamphetamine and amphetamine) are among the most commonly abused illicit substances in the world. In 2016, it was estimated that around 35 million adults worldwide used amphetamines.¹ The region with the highest annual use was North America at approximately 2% of the population. In the last few years however, there also appears to be a marked increase in consumption within other geographies, particularly East and Southeast Asia, where the amphetamines have been identified as one of the most worrying threats of drug use. Moreover, a rise in the use of Ecstasy (3,4 methylenedioxymethamphetamine; MDMA) in West Asia has been noted, though it is estimated that less than half of the tablets purported to be Ecstasy, truly contain MDMA, but are commonly found to contain methamphetamine, amphetamine, or ketamine.²

“According to Lange et al.,6 the worldwide estimated prevalence for FASD is 0.77% with regional differences ranging from 1.98% in Europe to 0.01% in the eastern Mediterranean region. A study analysing the prevalence of FASD in a UK population found a prevalence of 6–7.2%.7 The prevalence of FASD in Canadian school children was estimated to be between 2 and 3%.8 Another study by May et al.9 found a prevalence of 1.1–5% in first grade school children in the United States.9

Electromagnetic Spectrum Wavelengths

Electromagnetic waves are waves that can cause charged particles (such as electrons) to move up and down. These waves have both electrical and magnetic properties and can travel through gases, liquids, solids, and through empty space (or a vacuum) at nearly 300,000 kilometers per second (the speed of light).

Electromagnetic waves are characterized by wavelength and frequency. The wavelength is the distance between two wave crests or troughs. The highest point of a wave is called the crest, and the lowest point of a wave is called the trough. Frequency is expressed in hertz (Hz) and refers to the number of wavelengths that pass a fixed point in 1 second. The shorter the wavelength is, the higher its frequency will be. The reverse is also true. For example, radio waves have the longest wavelength and the lowest frequency.

Winter 1947, SK

Winter of 1947, Saskatchewan

This week-by-week lookback from the Oxbow Herald gives you an idea of how rapidly things went south on the Canadian Prairie. The storms started boxing day [1946], and continued, on and off, for weeks.

We can just imagine the exasperation in the newsroom of the Regina Leader-Post in mid-January, 1947, when the front page read Province Just One Big Snowdrift.” And even then, the worst was yet to come, with storm after storm finally culminating in a 10-day monster, ending on February 8, that Environment Canada calls the worst storm in Canadian railroad history.

Transportation shut down almost completely, with tracks shut for days or weeks, and some roads closed until the spring. Crews had to dig down for several metres just to find the tracks. Only the tops of telephone poles were visible in some districts.”

Peering into the secret world of life beneath winter snows

Snow covers some 40 percent of Earth’s land masses year in and year out.

…[Snow creates] the subnivium, a seasonal and sensitive refuge beneath the snow’s surface that’s insulated and maintains a constant temperature. It’s nature’s igloo.

“In a warmer world with less snow, winter soils would be colder because the insulating snow layer on top is reduced,” says Henry Gholz, a program director in NSF’s Division of Environmental Biology. “That has implications for farmers planting crops in spring, as well as for the many burrowing mammals, microbes and insects that overwinter in snow.”

The Deadliest Being on Planet Earth – The Bacteriophage (7:08)

bacteriophage (/bækˈtɪərioʊfeɪdʒ/), also known informally as a phage (/ˈfeɪdʒ/), is a virus that infects and replicates within bacteria and archaea. The term was derived from “bacteria” and the Greek φαγεν (phagein), meaning “to devour”. Bacteriophages are composed of proteins that encapsulate a DNA or RNA genome, and may have structures that are either simple or elaborate. Their genomes may encode as few as four genes (e.g. MS2) and as many as hundreds of genes. Phages replicate within the bacterium following the injection of their genome into its cytoplasm.

Bacteriophages are among the most common and diverse entities in the biosphere.[2] Bacteriophages are ubiquitous viruses, found wherever bacteria exist. It is estimated there are more than 1031 bacteriophages on the planet, more than every other organism on Earth, including bacteria, combined.[3] Viruses are the most abundant biological entity in the water column of the world’s oceans, and the second largest component of biomass after prokaryotes,[4] where up to 9×108 virions per millilitre have been found in microbial mats at the surface,[5] and up to 70% of marine bacteria may be infected by phages.[6]

“Sixty-seven Douglas fir trees of various ages were found to be intricately connected below ground by ectomychorrhiza from the Rhizopogon genus. Rhizopogon, which means ‘root beard’ in Greek, is commonly found living in a symbiotic relationship with pine and fir trees, and thus is thought to play an important ecological role in coniferous forests. Areas occupied and trees connected by Rhizopogon vesiculosus are shaded blue, or shown with blue lines, while Rhizopogon vinicolor colonies and connections between trees are coloured pink, or shown by pink lines. The most highly connected tree was linked to 47 other trees through eight colonies of R. vesiculosus and three of R. vinicolor.”

Giardia

Giardia is a microscopic parasite [about 10 um long] that causes the diarrheal illness known as giardiasis. Giardia (also known as Giardia intestinalisGiardia lamblia, or Giardia duodenalis) is found on surfaces or in soil, food, or water that has been contaminated with feces (poop) from infected humans or animals.

Giardia is protected by an outer shell that allows it to survive outside the body for long periods of time and makes it tolerant to chlorine disinfection. While the parasite can be spread in different ways, water (drinking water and recreational water) is the most common mode of transmission.

Adorable snowshoe hares found to routinely feast on their own dead

The Yukon hares ate lynx, they ate birds such as snow buntings and spruce grouse — and they ate their own brethren. A hare carcass left in a stand of trees in late 2015 was scavenged 24 times by fellow hares within the course of a week.

 “It was almost 15 per cent of the carcasses we had put out (that) had a snowshoe hare scavenging at them … so it seems like something that is pretty regular in their winter diet,” University of Alberta researcher Michael Peers, the study’s lead author, told the Edmonton Journal.

Inverse Square Law for Light Radiation

Inverse Square Law for Light Radiation

“The brightness of any point-source illumination diminishes rapidly with distance. This weakening of light is called fall-off.

It diminishes according to the inverse square law, which states that the effect of a light shining on a surface weakens at a rate comparable to the square of the distance between source and surface.

As the diagram above demonstrates, at twice the distance, the light is only one fourth as bright because the same rays must cover four times the area. At three times the distance, it drops to one ninth as bright.”

pH Scale Scratch Chemist

pH Scale & Notes (Scratch Chemist)

Proper Definition of pH

The pH scale was originally introduced by the Danish biochemist S.P.L. Sørenson in 1909 using the symbol pH. The letter p is derived from the German word potenz meaning power or exponent of, in this case, 10. In 1909, S.P.L. Sørenson published a paper in Biochem Z in which he discussed the effect of H+ ions on the activity of enzymes. In the paper, he invented the term pH (purported to mean pondus hydrogenii in Latin) to describe this effect and defined it as the −log[H+]. In 1924, Sørenson realized that the pH of a solution is a function of the “activity” of the H+ ion and not the concentration. Thus, he published a second paper on the subject. A better definition would be

pH=−log a{H+}

where a{H+} denotes the activity (an effective concentration) of the H+ ions. The activity of an ion is a function of many variables of which concentration is one.

  • Concentration is abbreviated by using square brackets, e.g., [H3O+] is the concentration of hydronium ion in solution.
  • Activity is abbreviated by using “a” with curly brackets, e.g., a{H3O+}  is the activity of hydronium ions in solution.

This gold mine was once so dangerous that it killed a toddler who ate snow two kilometres away.

Arsenic and Gold Mining   …   Canada’s taxpayers ante up billions to clean up the mistakes of the past.  Welcome to the Giant Mine, an abandoned gold mine in Yellowknife, capital of the Northwest Territories (see map).  The Canadian government first took charge of it in 1999 after the owner declared bankruptcy and walked away.  It is one of an estimated 10,000 orphaned or abandoned mines in Canada’s north that are now the government’s responsibility.  And it is full of arsenic trioxide, a compound that is produced by heating arsenopyrite ore, a mineral that has traces of gold.  Arsenic trioxide is odourless, tasteless, highly soluble—and lethal.  An amount smaller than a pea is enough to kill.  The Giant Mine has 237,000 tonnes of the stuff.
