Safety Emporium has a great lineup of gas cylinder signs, storage racks, lockouts, clamps and more. A hydrocarbon is an organic chemical compound that is comprised only of carbon C and hydrogen H atoms.
Many oils, fats, waxes, solvents and paraffin are either hydrocarbons or contain large hydrocarbon sub-units. Hydrocarbons can be divided into particular classes depending on their properties. Some examples are:. Hydrocarbons or other organic molecules that form a ring are called cyclic. Those that do not have rings are called acyclic or non-cyclic.
For example, cyclopentane C 5 H 10 is cyclic, while pentane C 5 H 12 is acyclic:. Note: The terms "saturated" and "unsaturated" also refer to the concentration of solutions. These have a much different meaning and context.
A saturated hydrocarbon or other organic molecule has utilized all of its bonding electrons to make single bonds to other atoms. It can not make additional bonds without removing an existing bond to another atom or group of atoms in the molecule.
An unsaturated hydrocarbon or other organic molecule contains double or triple bonds between certain atoms. These bonds may be broken and new atoms or groups of atoms attached without disrupting the existing skeleton of the hydrocarbon.

If a molecule contains a saturated hydrocarbon sub-unit, this sub-unit is called an alkyl group. If the sub-unit is an aromatic group this sub-unit is called an aryl group. For carbon, the maximum and ideal number of bonds is four. Let's look at an example. If we chemically add hydrogen atoms to the red carbons, this reduces the carbon-carbon double bond to a single bond and gives the red carbons four single bonds to other atoms. The resulting molecule, hexane also called n -hexaneis saturated because we can not add any more atoms to it without removing bonds to existing atoms or groups of atoms.
Safety Emporium has the solution to your laboratory needs with an extensive line of glassware. You may have heard the terms monounsaturatedpolyunsaturatedand saturated in reference to fats and oils. Saturated fats no double bonds contain long hydrocarbon sub-units alkyl groups. Examples are coconut oil and lard, which have a tendency to clog your arteries because of their chemical and physical properties.
Unsaturated fats, those with one mono or many poly double bonds, are less likely to form artery-clogging plaques. The following prefixes are commonly used for simple hydrocarbons, but are not part of the systematic naming scheme used by chemists. For systematic naming rules vital to name a hydrocarbon with more than one branch! The molecules shown above have the same chemical formula C 5 H 12but a different arrangement in each case, so we call them isomers.
These isomers of pentane have different chemical reactivity and properties because of their different molecular arrangements. For example n -hexane is a neurotoxin while neohexane is not.

He said he has now removed it. If he was able to earn a living as a full-time bettor, his performance as a pick-seller at Pregame offers little support. Bell sold 30 picks from October 2008 through March 2010. Eight months after his final sale, he came out of retirement to offer a freebie in college-football: Army as an eight-point underdog against Notre Dame.
Before launching Pregame, Bell offered free picks. But where was the money in that.
His NCAA domain squatting may offer a hint: The real profit was in lucrative referral deals with offshore sportsbooks. Bettors signed up for free picks, and Bell accumulated a massive database of names and email addresses that he could sell to sportsbooks. According to a Pregame advertising kit circa 2010, the average Pregame and FPBE user was a fairly avid bettor who played at multiple books.
Sportsbooks less able or inclined to spend six figures could sign up as standard advertisers. A testimonial of his is featured on the home page of WebPartners, an affiliate go-between and Costa Rica-based bookmaker.
A cookie-based tracking system and unique token ensured that those who clicked on the ads and then deposited money at Mybookie would be credited as referrals of WagerTalk. Every month thereafter, site heads would be sent a monthly statement and a check for their cut of those losses.
Industry standard Sportsbook Review gives Mybookie a C rating. WagerTalk ranked Mybookie as its top sportsbook. As Johnny Detroit was handling the arrangements with sportsbooks, Bell was doing his part to push their merged tout service to the public. Their break came in 2007, provided by disgraced NBA referee and heavy gambler Tim Donaghy. The figures he put out grabbed their attention, and Bell was invited onto CBS News, ABC News, and ESPN, quoted by the Wall Street Journal, Los Angeles Times, and the Associated Press.This is the only product in our lineup that offers all features and tools we considered.

One was a nice post discussing the challenges for AI in medicine by Luke Oakden-Rayder and the other was about the need for increased focus on basic research in AI motivated by AlphaGo by Tim Harford. Despite the excitement around AI and the exciting results we see from sophisticated research teams almost daily - the actual extent and application of AI is much smaller.
I was listening to the Effort Report Episode on The Messy Execution of Reproducible Research where they were discussing the piece about Amy Cuddy in the New York Times.
I think both the article and the podcast did a good job of discussing the nuances of the importance of reproducibility and the challenges of the social interactions around this topic. Sometimes, when I write a really long blog post, I forget what the point was at the end. I suppose I could just update the previous postbut that feels wrong for some reason.
I meant to make one final point in my last post about how better data analyses help you reason about the data. In particular, I meant to tie together the discussion about garbage collection to the section on data analysis. I just got back from the rOpenSci OzUnconf that was run in Melbourne last week. These events are always a great opportunity to meet people just getting started in the R community and to get them involved. As is typical for these unconferences, topic ideas were pitched via issues on the OzUnconf GitHub repo.
