Rare albino palm civet seized, handed over to Lucknow zoo

Saturday, August 30th, 2008

A rare albino palm civet that was seized with the arrest of two smugglers in Uttar Pradesh has been handed over to the Lucknow zoo, officials said here Saturday.

The Special Task Force (STF) seized the wild cat, along with some rare birds, from two smugglers in Meerut a few days ago.

“The duo, Jivan Thakur and Ashish, had caught these animals from the forests near the Uttar Pradesh - Uttarakhand border and were planning to sell them,” an STF official said.

“The general palm civet is found easily but this albino variety is very rare,” explained zoo director Renu Singh.

“The cat is omnivorous and likes to live on trees, particularly the palm tree. It has been kept in the nocturnal house of the zoo and we do not think any other zoo in the country has this species,” she added.

Tropical Storm Gustav approaches Haiti, Cuba

Tuesday, August 26th, 2008

Haitians were told to prepare for evacuations as Tropical Storm Gustav formed quickly Monday in the Caribbean on a path to hit — as a hurricane — the country’s denuded southern coast before moving on to Cuba, the Bahamas and Florida.

Haiti upgraded storm warnings to hurricane warnings along much of its coast Monday as Gustav closed in from the south.

By Monday afternoon, reports from an Air Force Hurricane Hunter aircraft indicated that top sustained winds had already reached nearly 60 mph (97 kph) as Gustav moved northwest, the U.S. National Hurricane Center in Miami said. Forecasters said Gustav’s center could pass near or over Haiti on Tuesday.

Floods and landslides were possible across Haiti’s southern peninsula, and the forecasts suggested the eye could pass very closely to the capital of Port-au-Prince, home to nearly 3 million people. Early Monday evening, the storm was centered about 180 miles (290 kilometers) southeast of Port-au-Prince.

Carnival Cruise Lines diverted one of its ships to a Mexican port instead of Montego Bay, Jamaica, to avoid the storm, company spokesman Vance Gulliksen said. Other cruise lines said they were closely tracking the storm’s path.

The commander of the Guantanamo military base in Cuba, where the U.S. holds about 265 men, many suspected of belonging to al-Qaida or the Taliban, ordered U.S. military personnel to prepare for the storm to hit late Tuesday or early Wednesday.

“We’re monitoring the track of … Gustav and reviewing our destructive weather plans and procedures,” said Army Maj. Richard Morehouse, a spokesman for detention operations at the base.

Vulnerable to high winds are dozens of tents pitched on an abandoned runway where those attending war-crimes trials for alleged terrorists are housed. No hearings are scheduled this week.

Morehouse told The Associated Press that the lockups housing all detainees “are capable of withstanding hurricane force winds and rain.”

Haitians were told to stay on alert for evacuations and to avoid crossing flooded rivers, the cause of nearly all 23 deaths on the greater island of Hispaniola during last week’s Tropical Storm Fay.

The agricultural ministry, already dealing with a food crisis and fighting to raise national production, advised farmers to put livestock in safe locations. All maritime activities also were suspended until further notice.

Few people in Haiti’s capital appeared to be aware of the brewing storm as rumors spread of new protests against high food and education prices planned for this week. Haitian radio reported that a handful of protesters burned tires Monday in Les Cayes, a town in the southwest.

“I didn’t know there was a tropical storm coming,” said Dunis Amilca, a 29-year-old resident of the oceanside Port-au-Prince slum of Cite Soleil. “I’m just going to stay in my house and watch out for it.”

Dominican authorities also issued storm warnings and advised small boats to remain in port, even on the north side of the island of 17 million people.

Meanwhile, two other tropical storms were lashing the southeastern U.S. and Mexico’s Pacific coast.

The remnants of Fay brought heavy rain and winds from Georgia to Louisiana. Floridians were still mopping up floodwaters from a storm that stuck around for a week and made a historic four landfalls, dumping more than 30 inches (76 centimeters) of rain along the central Atlantic coast.

The National Weather Service said the vestiges of Fay would deluge northern Georgia on Monday and Tuesday with 3 inches (8 centimeters) to 5 inches (13 centimeters) of rain expected in the Atlanta area and up to 8 inches (20 centimeters) in northeast Georgia. In Alabama, flash flood and tornado warnings were posted.

In Mexico, Tropical Storm Julio dumped rain on the southern half of the Baja California peninsula Monday before heading toward the northern Gulf of California.

A tropical storm warning was issued for the peninsula’s east coast from Loreto to Bahia de los Angeles, and for the mainland from Guaymas to Puerto Libertad.

But Julio caused little major damage and was expected to weaken to a depression by Tuesday. Forecasters said it would likely drench the U.S. Southwest in coming days.

The National Hurricane Center said Julio was located about 15 miles (25 kilometers) north-northwest of Santa Rosalia, Mexico, and heading north-northwest at 12 mph (19 kph). It had top winds near 40 mph (65 kph).

Prince Charles sees red over GM crops

Friday, August 15th, 2008

Prince Charles drew criticism with an outspoken attack on industrial farming Wednesday, warning genetically modified food could be the “biggest disaster environmentally of all time.”

Charles said millions of small farmers around the world could be driven off their land into “degraded and dysfunctional conurbations of unmentionable awfulness” by the rise of global conglomerates.

The heir to the throne is a long-term supporter of sustainability and locally produced food and often speaks out on environmental issues.

He has an organic farm on his Highgrove estate in Gloucestershire and set up the Duchy Originals brand, which sells exclusively organic produce, in 1990.

But his latest comments have drawn criticism that he is a “Luddite”.

The Daily Telegraph journalist who conducted the interview wrote that Charles “let rip” and started “jabbing his finger” and “bouncing in his chair” when asked whether large-scale food production was the future.

“What, all run by gigantic corporations? Is that really the answer? I think not. That would be the absolute destruction of everything and… the classic way of ensuring that there is no food in the future,” Charles told the paper.

He added that “clever” genetic engineers had put the world on course for the “biggest disaster environmentally of all time.”

The world should be working “with nature. We have gone working against nature for too long,” Charles said.

Labour lawmaker Des Turner, who is on the House of Commons science and technology select committee, criticised the comments, telling London’s Evening Standard paper that Charles “has got a way of getting things absolutely wrong.

“It’s an entirely Luddite attitude to simply reject them (GM crops) out of hand,” he added.

Another Labour lawmaker, Ian Gibson, told the paper: “Prince Charles should stick to his royal role rather than spout(ing) off about something which he has clearly got wrong.”

But the future king attracted support from environmental groups including Friends of the Earth.

Prince Charles has hit the nail on the head about the damaging false solution that GM crops present,” said its campaign director Mike Childs.

“GM crops will not solve the food crisis — and forging ahead with an industrialised farming system will continue to fail people and the environment around the world.”

The comments come amid rising concerns worldwide over rapidly rising food prices.

The World Bank estimates that food prices have almost doubled over the past three years, and its president Robert Zoellick has said two billion people are affected by the food crisis.

I’m thinking of moving to Florida but wonder what parts get hit by hurricanes (katrina victim) I don’t want to lose all my stuff again but I realize that the whole state can’t be getting hit or else no one would live there. So what cities in Florida are in the safe zone?

No matter where you stay in Florida, whether you are up in the north, in the central Orlando area, on either the western Gulf Coast or the eastern Atlantic coast or down in the Florida Keys, you could be caught by a hurricane or a tornado.

The hurricane season in Florida runs from the beginning of June to the end of November with mid August to mid October being the height of the season
If you are staying in a region which is susceptible to hurricanes, it makes sense to buy a portable radio that picks up NOAA weather broadcasts

——

Pretty much any part of Florida is susceptible to being struck by hurricanes. While any one hurricane will likely not significantly affect the entire state, one cannot say in advance which part will be unaffected. To escape the worst of the winds and storm surge, you want to be inland, away from the coastline as much as possible. But then again, inland flooding is the most dangerous aspect of a tropical system. Thus I cannot say that any city in Florida could be called “safe”.

False to that other answer. Medications, after their expiration date may or may not loose their potency. These meds are tested for a certain period of time and their expiration shows either when they would start loosing the potency or if the testing period is over (usually 3 years). You can still take the med years later, obviously if it is loosing effect get new script.

A 5.00 liter sample of gas measured at 27.0?C and 1.25 atm of pressure has a mass of 10.13 g. What is the mole

a)39.9
b)0.898
c)2.57
d)2.50 x 10

I assume that you want to know the molecular mass of the gas.
PV = nRT
126.625 * 5 = n * 8.31*300
n = 126.625*5/8.31*300
n = 0.254 moles
Mass is 10.13, therefore molar mass = 10.13/0.254 = 39.9

Answer is a) above.

Can anybody tell me what a good organic dewormer will be for cattle and calves.

According to the National Organic Standards Board, diatomaceous earth (DE) has proved successful for many dairy farmers as a preventative measure in healthy cattle. He suggests mixing the DE with grain mix for pastured cattle at a rate of 8 to 10 pounds per ton throughout the grazing season. For heavy infestations conventional therapy is recommended. Ivermectin is the only conventional (synthetic) paraciticide that is cleared with the National Organic Program for use as a dewormer, and only in breeding stock, not lactating or feeder animals.

———

The best organic dewormer for cattle or horses would be tobacco. Prior to modern veterinary sciences, the old farmers and mule skinners in the Southern and Midwest states would treat their stock to two hand fulls of dry tobacco in a gallon of corn or oats.twice yearly. Dichotomous earth is an inorganic substance, but works well also. It is similar to ground glass and cuts the worms as an abrasion..

What is a function of lipids?
to dissolve other nutrients
to dilute chemical reactions
to store energy
to control chemical reactions

Lipids are used as insulation, and lipid derived compounds can be signalling agents for diverse reactions ( like the prostaglandins and leukotrienes. However, lipids are well suited as strorage forms of energy because being non-polar they take up less room than the hydrated glycogen which is a storage form of glucose . Fatty acids , derived from triglycerides in storage can be “burned ” using beta oxidation and ultimately the acetyl CoA goes through TCA in a manner like that of pyruvate from glucose . Fatty acids yield considerable more energy that carbohydrate . The most prepnderant fatty acids in our triglycerides are > 14 carbons in length and will geenrate upwards of 112 ATPs per mole compared to glucose ( 36 or 38 depending on shuttle ). Stearic acid, the 18 carbon fatty acid yields 146 ATPs per mole ..

My Grandson wants to know what makes grass. How do you answer a 10yr old so he can understand ?

You have a great chance to teach a curious 10 year old a valuable lesson here that will peak his imagination and stay with him for many years to come. Pick up a small bag of potting soil and some grass seed. Plant two pots, water, place one in the sunlight, one in the dark. After the seed start growing, you can show him that grass came from the seeds. You can explain to him how the sunlight reacts with the plant to produce the green color (chlorophyll), and produces food which the plant lives and grows on through the process of photosynthesis where the plant breaths in CO2 an breaths out O2. Then take the pot out of dark, the plants will be white and spindly, because they have had no sun. Put it in the sun and watch them turn green and start to grow together with your Grandson. You might have a budding scientist there.

Tiny living things called cells, like we have in our bodies. You can’t see them without a microscope because they are so small. Grass is green because it’s got chlorophyll (a word which he’ll probably forget, but it sounds exciting, and I know when I was 10, I would have liked it!), which is green, and this is needed to turn sunlight into energy, which is why plants need to be in the sun or they’ll go yellow or brown and die.

If he wants to know the basics about seeds and things, grow some cress with him so he can see how it works.

Time Zone Help?

If it is 11:55 in Georgia. What time is it GMT+1 time? I have to do something at 9 am GMT+1 time and I was wondering what time that was Eastern Time.

Georgia time is GMT - 4.
At 11:55 PM in Georgia it is 4:55 AM in GMT + 1.
At 9 AM in GMT + 1 it will be 4AM in Georgia.

——

GMT = Greenwich mean time, Greenwich is a place in Britain, which is located at ZERO deg. longitude. Each degree = 4 min. Locate any place on earth, know its longitude say 50 deg. then multiply 4 x 50 = 200 mins. If it is in Eastern side, then substract 200 mins from UK’s time, if it is in Western Side, then ADD to UK time.
Georgia longitude is 43.3 East. so taking it as 44 for ease of calculations 44 x 4 = 176 mins = 2 hrs 56 mins. Being in Eastern zone, then from UK’s time deduct 2 hrs 56min. you will get Georgias time.

To get UK’s time, ADD 2 hrs 56 min to Georgias time to get time in Great Britain.

This methods if for finding exact time at a place. However, the time zone meridian for Georgia may be passing through a different longitude. So get that info.

When a time is shown as GMT +1 hr…it means add ONE hour to UK’s time.
