Below is excerpt on Risky Eating Behaviors from Dietary Guidelines for Americans, 2010 published on January 31, 2011. Reference: http://www.mypyramid.gov/guidelines/PolicyDoc.pdf

Harmful bacteria, viruses, and parasites do not always change the look or smell of food. This makes it impossible for consumers to know whether food is contaminated. Consumption of raw or undercooked animal food products increases the risk of contracting a foodborne illness.

Raw  or  undercooked foods commonly eaten in the United States include:

eggs (e.g., eggs with runny yolks),
ground beef (e.g., undercooked hamburger),
milk and milk products (e.g., cheese made from unpasteurized milk),
seafood (e.g., raw oysters).

Cooking foods to recommended safe minimum internal temperatures and consuming only pasteurized milk and milk products are the best ways to reduce the risk of foodborne ill-ness from animal products. Consumers who prepare foods that require eggs to remain raw (e.g., eggnog, hollandaise sauce, homemade ice cream) should use pasteurized eggs or egg products. Consumers who choose to eat raw seafood despite the risks should choose seafood that has been previously frozen, which will kill parasites but not harmful microbes.

Recommended Safe Minimum Internal Cooking Temperature for most meats, ground meats, poultry and egg dishes is in the range 160 – 165 degrees Fahrenheit (°F). Eggs should be cooked until yolk and white are firm. Recommended safe minimum internal temperature for fish is 145 °F.

An example of daily food plan guidelines generated by MyPyramid.Gov is provided below. This plan is a 2400 calorie food pattern and based on average needs for a 34 year old male, 5 feet 9 inches tall, physically active less than 30 minutes a day, in the healthy weight range. Eating these amounts from each food group daily may help you gradually reach a healthier weight. (Personal calorie and nutrient needs may be more or less than the average, and it is recommended to consult a qualified nutritionist for a personalized plan.)

GRAINS                 8 ounces
VEGETABLES          3 cups
FRUITS                  2 cups
MILK                     3 cups
MEAT & BEANS      6.5 ounces


Make Half Your Grains Whole
Aim for at least 4 ounces of whole grains a day.

Vary Your Veggies
Aim for this much every week:
Dark Green Vegetables = 3 cups weekly
Orange Vegetables = 2 cups weekly
Dry Beans & Peas = 3 cups weekly
Starchy Vegetables = 6 cups weekly
Other Vegetables = 7 cups weekly

Oils & Discretionary Calories
Aim for 7 teaspoons of oils a day.
Limit your extras (solid fats & sugars) to 360 Calories per day.

Physical Activity
Physical activity is also important for health. About 60 minutes of moderate to vigorous activity most days can help you manage your body weight and prevent gradual gain. About 60 to 90 minutes daily can help you maintain weight loss. If you are inactive, work up to these amounts gradually.

Comments on MyPyramid.Gov Daily Food Plan guidelines
MyPyramid.Gov Food Plan recommends 3 cups of low-fat or non-fat milk every single day for an adult person! From my experience most adult americans do not consume 3 cups of milk on a daily basis. (While yogurts and yogurt smoothies are  an excellent source of calcium, most yogurt based products are “overloaded” with sugars.) Dear reader, how many cups of milk did you drink yesterday?

BP published its internal investigation report for Deepwater Horizon rig explosion at Macondo well in the Gulf of Mexico on April 20, 2010 (Links to Video, Presentation Slides, Executive Report and Full Report are below).

The investigation found eight major factors that contributed to Macondo well explosion and oil and gas leak. A sequence of failures involving a number of different parties, mainly BP, Transocean and Halliburton, led to the explosion and fire which killed 11 people and caused widespread pollution in the Gulf of Mexico.

BP’s managers and contractors involved with well exploration made mistakes that contributed to the tragedy. In its report BP blamed many of the errors on Transocean Ltd, the owner of Deepwater Horizon rig, and on service provider Halliburton Co.

Bloomberg.Com reports that: “BP’s report concealed the well’s “fatally flawed” design, which “set the stage” for the explosion, Vernier, Switzerland- based Transocean said Sept. 8. The driller, Transocean, cited a series of cost-savings decisions by BP that added risk. Cathy Mann, a spokeswoman for Houston-based Halliburton, said the report had “substantial omissions and inaccuracies” and that BP dictated design and testing procedures for the well.”

As of Tue, Aug 17, 2010 BP is on standby to get government approval to drill final 50 feet to intersect MC252 well annulus (space between rock formation and well casing) at about 800 feet above oil reservoir.

Below are quotes from BP’s briefing with Kent Wells on sealing Macondo well (Aug 10, 2010):

“We do know that we pumped about 200 barrels of cement or so out of the casing. Did it go into the reservoir? Did some go into the reservoir? Did some go up in the annulus? That’s an unknown.”

“We’re planning to intersect the well about 800 feet above the reservoir. And where we are right now with the relief well, we’re just at the shoe of the outer casing. And so we’re now going to start to go down to the place where we can intersect the annulus. And the annulus we’re describing is the annulus between the casing of the Macondo well and just the rock formation. It’s not an annulus between casing and casing. We’re going to intersect it at a point where it’s basically rock and then there’s an annulus and then there’s casing. And that’s where we plan to intersect.”

“And what we don’t know is exactly what we’ll find in that annulus. It could be mud. It could be oil. It could be cement. We just don’t know.”

Kent Wells of BP said on August 6 during the briefing that BP pumped just a little over 500 barrels of cement down the casing. He added “I think it was roughly about 200 barrels into the formation and the rest remained in the casing”. BP plans to remove failed Blowout Preventer after well is killed on August 15 – 20, and install a formal plug during regulatory abandonment procedure.

Starting from mid June, Congress made multiple requests to BP to explain condition of the leaking well and provide facts about possible oil leak into rock formation surrounding the wellbore (read letters here).

All along since the Macondo Well ruptured on April 20 in the Gulf of Mexico, BP was designing a well cap from “scratch” with two objectives in mind: 1) to contain all leaking oil and 2) to have possibility to shut-in the well. As we learned from Congress, Steven Chu, Admiral Thad Allen and independent sources BP knew about sea floor oil leaks they discovered during Top Kill operation, but was not forthcoming about oil sipping from sea floor.

It is not surprising after Top Kill procedure BP’s press briefings did not mentioned anything about designing an impermeable well cap. The first week of July BP installed mini Blowout Preventer, a cap with three RAM valves that serves dual purpose: to contain all leaking oil and to shut-in well if wellbore can hold oil reservoir pressure.

Admiral Thad Allen said it took so long to design this cap because BP had to manufacture and test this specially designed cap from scratch.

Kent Wells of BP mentioned in one of BP’s briefings that Macondo well will be considered intact, or unbroken, if wellbore can hold 8,000 – 9,000 psi pressure during well integrity test. If pressure is found significantly lower than 8,000 psi that would imply oil sips into surrounding rock formation. Oil leaking into rock formation poses a great risk of sea bed erosion and all measures are taken to avoid such outcome.

Dr. William Kerr of Harvard Business School Published a Study on Immigrants and US Innovation.

Abstract:

How does high-skilled immigration affect innovation in receiving countries? This column examines how large fluctuations in the admissions levels of H-1B visa holders between 1995 and 2008 influenced US patenting. It suggests higher H-1B admissions increased US innovation through the direct contributions of the immigrants without crowding out those of natives.

BP has installed and bolted down an adapter, called ‘spool’, on top of failed Blowout Preventer (BOP) at leaking well (Macondo, MC252) in the Gulf of Mexico. An installation of a stack of valves on top of spool is currently in progress. Pictures of a spool adapter and of a stack of valves are shown below. Once stack is installed, BP will commence well integrity test to determine if well can hold pressure (shut-in pressure) without deterioration of rock formation or seabed leaks.

Should the well pass the 48-hour pressure test, BP may shut it, Doug Suttles, the company’s chief operating officer for exploration and production, told reporters today on a conference call. The test will start as early as this morning, once a stack of valves is bolted atop spool adapter, he said. A relief well BP is drilling will still be needed for a permanent plug.

BP’s Macondo well has been leaking into the Gulf of Mexico as much as 60,000 barrels of oil a day, according to a government estimate, since an April 20 drilling-rig explosion that killed 11 workers. The pressure test, to be monitored by seismic sensors on the seafloor, may determine whether the well bore can withstand the pressure of being shut, National Incident Commander Thad Allen said today in a CNN interview.
