Industrial and Mining Water Research Unit
The Industrial and Mining Water Research Unit (abbreviated IMWaRU) is a research group. They are part of the School of Chemical and Metallurgical Engineering at the University of the Witwatersrand, Johannesburg.
The unit deals with many water issues in industry and mining.
The unit works with the Schools of Law, Chemistry, Civil and Mining engineering at the University.
Members of the group have given presentations at:
The main location IMWaRU is in the Richard Ward Building on the East campus of the University.
The group has a broad range of research publications in the areas as listed below:
Blood doping
Blood doping is a way of increasing the number of red blood cells in the bloodstream. This is done to improve athletic performance. Because blood cells carry oxygen from the lungs to the muscles, a having more red cells in the blood can improve an athlete’s aerobic capacity (VO max) and endurance. Many methods of blood doping are illegal, particularly in professional sport.
There are a number of different methods. Frozen blood taken from the individual previously can be used for a later transplant; packed red cells from a compatible donor may be used, and blood substitutes may be used. The growth area in illegal blood doping of athletes is blood substitutes.
SummerSlam (2014)
SummerSlam (2014) was a professional wrestling pay-per-view show made by WWE. It was held on August 17, 2014 at Staples Center in Los Angeles, California. It was the twenty-seventh SummerSlam event held by the WWE.
The main event saw Brock Lesnar defeat John Cena to win his fourth WWE World Heavyweight Championship.
Bacteriology
Bacteriology is the study of bacteria. Bacteriologists study, identify, classify, and describe bacterial species.
Microorganisms such as bacteria, protozoa, fungi, and viruses are studied by "microbiologists". However, bacteriology is a distinct science, because the make-up and inheritance of bacteria is rather different from the other groups.
Ferdinand Cohn
Ferdinand Julius Cohn (24 January 1828 – 25 June 1898) was a German biologist. He is a founder of modern bacteriology and microbiology.
Cohn was born in the Jewish quarter of Breslau in the Prussian Province of Silesia. This is now Wroclaw, Poland. Starting at age 16 he studied botany under Heinrich Goppert at the University of Breslau. He then moved to the University of Berlin. At age 19 in 1847 he received a degree in botany at Berlin.
In 1849 he returned to the University of Breslau and he remained at that university for the rest of his career as a teacher and researcher. His father had bought for him a large and expensive microscope, which the University of Breslau and most universities did not have at that time. They had microscopes, but not so good as his. It was Ferdinand Cohn's main research tool in the 1850s.
In the 1850s he studied the growth and division of plant cells. In 1855 he produced papers on the sexuality of "Sphaeroplea" and later "Volvox". In the 1860s he studied plant physiology. Cohn was the first to classify algae as plants, and to define what distinguishes them from green plants.
From 1870 onward he mostly studied bacteria. He published over 150 research reports during his lifetime. The University of Breslau became an innovative center for plant physiology and microbiology while he was there. His classification of bacteria into four groups based on shape (sphericals, short rods, threads, and spirals) is still in use today.
Among other things Cohn showed that "Bacillus" can change from a vegetative state to an endospore when conditions are hard. Heat resistant spores of "B. subtilis" caused a controversy over spontaneous generation. Cohn explained why boiled infusions of hay and cheese could still get microbial growth. It was because they contained heat resistant spores.
Plant physiology
Plant physiology is the part of botany which studies how plants work. That is the physiology of plants. Using a variety of methods, botanists study how plants reproduce, grow, get nutrients, photosynthesise, get water, and so on.
The main topics of plant physiology are photosynthesis, respiration, plant nutrition, plant hormones, tropisms, nastic movements, photoperiodism, photomorphogenesis, circadian rhythms, environmental stress physiology, seed germination, dormancy, stomata function and transpiration.
Elimination Chamber (2014)
Elimination Chamber (2014) (No Escape (2014) in Germany) was a professional wrestling pay-per-view show made by WWE. It was held on February 23, 2014 at Target Center in Minneapolis, Minnesota. It was the fifth Elimination Chamber event held by the WWE.
There were two main events. The first saw The Wyatt Family defeat The Shield and the second saw Randy Orton successfully retain his WWE World Heavyweight Championship in an Elimination Chamber match against Daniel Bryan, John Cena, Cesaro, Christian and Sheamus.
Stanisław Mikulski
Stanisław Mikulski (1 May 1929 – 27 November 2014) was a Polish theatre, television, movie actor. He was a host of the Polish game show "Wheel of Fortune" ("Koło Fortuny"). Mikulski was known for starring in the leading role in the 1967-1968 television series "Stawka większa niż życie".
Mikulski died in Warsaw, Poland, aged 85.
Mollicutes
The Mollicutes are a class of bacteria with no bacterial cell wall. "Mycoplasma" is the best-known genus.
They are very small, only about 0.2–0.3 μm in size, and have a very small genome. Most move about by gliding across host cells, but "Spiroplasma" are helical and move by twisting.
Mollicutes are parasites of various animals and plants, living on or in the host's cells. Many cause diseases in humans. "Mycoplasma" and "Ureaplasma" stick to cells in the lungs or sex tubes like the urethra. "Phytoplasma" and "Spiroplasma" are plant pathogens with insect vectors. Bugs such as leaf-hoppers (Homoptera) are the vectors. They deliver the parasites which they stick their mouth-parts into a plant to suck its sap.
Dave (movie)
Dave is a 1993 American comedy movie directed by Ivan Reitman. It stars Kevin Kline, Sigourney Weaver, Frank Langella, Kevin Dunn, Ving Rhames, and Ben Kingsley.
It is about the President of the United States (Kevin Kline) suffering a stroke and the White House Chief of Staff (Frank Langella) and assistant (Kevin Dunn) hiring a double (also Kevin Kline) to impersonate the president.
It's movie score was composed by James Newton Howard. It was released to very positive reviews on May 7, 1993. It has a 94% on Rotten Tomatoes. Critic Roger Ebert gave the movie 3.5/4 stars. It was nominated for an Academy Award for Best Screenplay.
