EDF gives up outmatching on Constellation Energy

The financial crisis obliges EDF to review to the decrease his/her/its ambitions. The French group renounced indeed, Wednesday October 15, to outmatch on the man's offer business Warren Buffet to put the hand on the American electrician Constellation Energy.

"Considering the present situation of the financial markets and in particular of the difficult conditions on the market of the credit to the enterprises, EDF notes, after discussions with several potential American partners, that the conditions are not united to this stage to present a new offer on Constellation Energy", indicate the French group in a communiqué.

In a first time, Pierre Adonis, the CEO of EDF, had affirmed that his/her/its group had "the financial flexibility" to achieve the operation, having a strong signature at a time by the banks and a cash-flow of 10 billions of euros. Even some weeks ago, EDF could have borrowed 13 billions of euros thus from seven banks, for the acquisition of British Energy. But visibly what was even possible became today a lot more complicated.

It was not yet the desire that missed to EDF. M. Adonis had not appreciated the irruption of the American billionaire indeed in the file Constellation, of which EDF detains 9,51%. M. Buffet had proposed, September 19, 4,7 billions of dollars (3,5 billions of euros) to take the control of the American group.

However Constellation is in a way the head from bridge of the French nuclear industry to the United States. EDF concluded an agreement notably in July 2007 with this business to construct the nuclear plants using reactors of third generation, so-called EPR.

In spite of his/her/its renouncement, the French group confirms its objective to develop "at least 4 reactors of EPR type in the United States in partnership with one or several American actors" and that it "continues to examine all possible options" attentively in this sense.

Sleep: more harmful caffeine after 40 years?

Caffeine is the psychostimulant the more used at the world, but one again ignores how it acts on the sleep after 40 years, "observes Julie Carrier, a professor to the Department of Psychology of the university of Montreal.

 

And it is what the searcher will tempt to determine, in the setting of a survey that she directs currently in the center of survey of the sleep of the hospital of the Sacred Heart of Montréal1.

A more fragile sleep while aging

Several studies on the sleep showed that from about forty, the sleep is weakened by the gradual loss of "slow deep sleep."

 

"This stage of the sleep occurs in the beginning of the night and constitute the period the deepest and intense, during which the brain is the most synchronized", explain Julie Carrier.

One does not know the role that the slow deep sleep plays precisely, but it is associated to the hormone of growth and, probably also, to the regeneration of energy, according to the searcher.

However, caffeine could weaken this stage of the sleep more, at the time of life where the quality of the sleep decreases little by little.

He / it is acquired that a "dose" of caffeine in the evening disrupts sleep, but he / it can be in the same way some to another moment of the day. "For example, a worker of night who takes a coffee at 5 o’clock of the morning will alter his sleep of recovery", she / it illustrates.

Also, even at people having a timetable of day, took the morning coffee can alter the repairing sleep during the night. our main products is spring mattress, zig zag spring and torsional spring for agriculture machine. compression spring, extension spring, torsional spring and other kinds of springs for automobile, machine and other usages.>>more

 

A Sleep "Connected"

In the setting of the survey that she / it direct, Julie Carrier tempts to measure the effect of caffeine on the sleep of middle age people, with participating adepts of caffeine and others who do not consume some, therefore.

Our colleague journalist Rene Leon of Cotret, who does not take any caffeine, was suitable to the experience: he / it slept three nights in the clinic of the sleep of the hospital of the Sacred Heart, at the rate of one night per week , During three weeks.

To every session, one welcomed it while installing close to him about thirty electrodes on the head. Thereafter, he / it had to do different tests of alertness and performance and had to provide samples of saliva to different intervals. Then 30 to 22 hours, he / it got in bed.

"I have been astonished to achieve that, in spite of the presence of electrodes, I slept more or less normally. I am myself there more quickly than I would have believed it and I felt accustomed neither bread nor annoyance", underline the volunteer.

The experience will also have allowed him to know of in more on his / her / its own sleep. "I now know with certainty that I do not make of the sleep apnea, that I fall asleep in about ten minutes, that I have six periods of dreams on average per night and that my share of really deep sleep is the least that well one of a young man of 25 years ", pursues Rene Leon of Cotret.

And the journalist’s curiosity did not make him default: "I liked to tempt to discover what week I had received the tablets of caffeine or the placebo tablets. Did I feel" more effective "to the tests of vigilance during the second week and did I take a lot of time to lull me after being wakened me toward 3 hours of the morning up … But this was caffeine or the placebo effect? I am in a hurry to know! ", He / it concludes.

Cancer of the prostate: useful, the systematic tracking?

A program of systematic tracking of the cancer of the prostate, put in place in Austria, would have reduced the number of death assigned to this cancer, indicate a recent étude1.

More of 85% of the men aged of 45 years to 75 years of the state of Tyrol underwent at least a test of tracking of the cancer of the prostate between 1993 and 2005. This test consists in a blood test to measure the rate of prostate specific antigen (PSA). The rate of APS is an indicator of the presence of a cancer of the prostate.

In 2005, at the men of less than 80 years, the death rate attributable to the cancer of the prostate in the state of Tyrol was of 54% less than the elevated cases of death estimated by the researchers. This proportion was of 29% in the rest of Austria where the systematic tracking was not offered. The researchers estimated the cases of death while being based on the death rates of 1986 to 1990.

The reduction of the number of death can explain itself by the premature tracking of the cancer of the prostate, that improves the rate of success of the treatments, note the authors of the survey.

Another sound of bell

The systematic tracking of the cancer of the prostate does not make the unanimity among the physicians. To Canada, the medical processes do not recommend to conduct the systematic tracking of the cancer of the prostate since the capacity of the tests to improve the odds of survival and to lengthen the life span is not demonstrated.

The College of the physicians of Quebec as well as the association of the urologists of Quebec suggest to discuss with a physician before undergoing a test in order of tracking to know his / her / its profits and his / her / its inconveniences.

The cancer of the prostate touches a man on eight before the age of 80 years and 1 on 27 will die some

Arthritis: a medicine would increase the risk of skin cancer

A systematic tracking of the skin cancer could be beneficial for the patients affected by rheumatoid arthritis, sustain Australian researchers.

It is that, according to their results, the cases of skin cancer were three times more elevated among the subjects suffering from arthritis that took the methotrexate, a medicine current antiarthritique, that in the population in general.

Arthritis: a medicine would increase the risk of skin cancer

This survey is the first to establish a tie between this medicine and the risk to be reached of a melanoma, the researchers affirm.

The patients under medication were also five times more to be reached to risk of non-Hodgkin lymphoma (cancer of the lymphatic system) and three times more to risk to suffer from a cancer of the lung, reveal the results. Other studies already established some ties between these two types of cancer and people affected by rheumatoid arthritis.

In a general way, the topics of the cohort saw increase to 50% of their risk to be reached of a cancerous tumor.

The researchers followed, during about ten years, 459 arthritic patients who took the methotrexate. This medicine has the effect of slowing down the progression of the rheumatoid arthritis, an illness during which the patient?fs immune system tackles the joints.

Done stress? Watch by the window!

To observe the nature by the window can be soothing for a stressed person. But to look at the same stage on a plasma screen the East him as much? "Not more that to look at a wall," some researchers affirm américains1.

They led an experience by 90 students of the university of Washington who have been submitted to a minor stress in a context of office work.

According to the results, the topics that watched by the window recovered a normal rhythm more quickly cardiaque2, compared to those contemplated that a white wall. And plasma screen did not have a better effect on the reduction of the rhythm of the heart that the wall of an office.

The participants to the survey, aged of 18 years to 34 years, had to sit down to an office and do four mental tasks. A minor stress was provoked by the explanation of the tasks to accomplish before every session.

The third of the participants was seated to offices placed before a window with view on a fountain and trees. The second third of the students was installed before a plasma screen to high definition, of identical size to the window and showing the same stage outside in real time. The last 30 participants were seated in front of a wall.

Caffeine and carbohydrates, a winning combination for the athletes?

The consumption of caffeine and carbohydrates could help the athletes to recover more quickly after an intensive practice, according to a survey australienne1 small.

The caffeine-carbohydrate combination would allow the muscles to redo their reserves more quickly in glycogen, their main fuel during a physical effort.

The experience has been led by seven high-level bicyclists. These have been submitted to two intensive sessions of stationary bicycle. Following one period of practice, they should have ingested a drink containing of the carbohydrate; after the other session, one gave them the same drink with, in addition, of caffeine.

According to the results, one hour after the practice, the bicyclists presented similar rates of glycogen, no matter the drink consumed. However, four hours after having drunk the mixture containing caffeine, their reserve in glycogen was 66% more elevated than after having drunk the other drink.

Their rates of glucose and insulin were as superior, as well as the quantity of proteins that would be responsible for transporting glucose to the muscles toward.

What is the quantity of caffeine necessary to drag such an effect? In the present survey, the absorbed drink contained the equivalent of about five cups of coffee. The researchers now want to verify if a less elevated dose could have the same effect. It is necessary to say that some of the athletes underwent the backlash of a strong consumption of caffeine: some said to have had the unrest of sleep or to have endured tremors.

This preliminary clinical test would be the first to underline the regenerative effect of caffeine and carbohydrates on the muscles of the athletes after an intensive effort. Other studies already showed that the combination of carbohydrates and caffeine was beneficial to the athletes before and during the practice.

To be active to 50 years to keep the mind alert

To make the exercise regularly to 50 years and more would protect the cerebral functions against the cognitive decline, reveal a étude1 of the well-known Mayo Clinic.

The topics that had practiced a physical activity curbed from two to five times per week as they were aged of 50 years to 65 years had less risk to see their cognitive functions declining, the researchers observed.

These results have been gotten while inquiring into the previous physical activities of 868 individuals aged of 70 years to 89 years. Among these, 128 light endured cognitive decline and 740 presented normal cognitive functions.

The light cognitive decline reaches the nerve cells that participate in the process of the thought. The people who stand some can function normally in their daily activities. They feel however, on occasion, of the difficulties to remember details of conversations or precise events, explain the authors of the survey.

Most patients affected by light cognitive decline see their state worsening with time and Alzheimer’s illness is often the reason of it, they specify.

Acupuncture and migraines: more that an effect placebo

The classic acupuncture would be more efficient than a placebo treatment to treat the migraine, according to a survey italienne1.

Up to here, the clinical tests had given the results indicating that the acupuncture would be efficient to relieve the headaches, but not more that the placebo treatments (needles inserted out of the valid points of acupuncture) 2.

In order to have the clean heart of it, the Italian researchers led a clinical test by 160 migraine. Lasting six months, all patients took the rizatriptan, if need be, to relieve the pain. The efficiency of this medicine is recognized for the treatment of the migraine. The participants have been divided in four groups of 40 sujets3.

According to the results, the participants who received acupuncture treatments of classic (group 1) were the only ones to feel a meaningful reduction of their symptoms after six months of session. They were also the only ones to decrease their medication to the term of the test.

However, the researchers observed an effect at the placebo participants of the group 2. The needles were placed on the points of acupuncture, but were not driven in skin. These topics noted a reduction of the pain all the same after three months of treatment. They also decreased their medication, but the effect dimmed at the end of six months.

The patients whose needles were inserted out of the valid points of acupuncture (group 3) and those that only took the rizatriptan (group 4) felt an improvement of their state also, but not as much as those of the groups 1 and 2.

Acupuncture and migraines: more that an effect placebo

The authors of the survey conclude that the artificial acupuncture has an effect on the placebo migraine, but that the real acupuncture procures lasting kindness superior to those of a placebo, as well as to those of the rizatriptan.
