Every evening when I return from work, there are four or five dead mice stacked neatly on their doorstep. Gone in the morning, new ones in the evening.
What the hell is going on?
Is this some sort of thing people do now or what?

The specific heat of substance A is greater than that for substance B. If both sample sizes are the same and they both start at the same temperature and equal amounts of heat are added to both these substances, the one reaching the HIGHER temperature, assuming no phase change occurs for either, will be

substance A.
could be substance A or B.
no difference in the final temperatures.
substance B.

Water is stored in a dam. When the sluice gates are opened, water rushes out and drives a turbine to produce electricity. How is the energy changing form in the process?






Also if you aren't gonna help me then please dont respond!!!

Also, state which substances are being oxidised and which are being reduced. Then fully balance the equation
[MnO4-] +H2O2+[H+] => [Mn2+] +O2+H2O

MONTREAL (CP) - A 65-year-old Quebec man who received a new long-term mechanical heart last month is being described as the only living Canadian without a pulse.


Dr. Renzo Cecere implanted the "Heartmate II" mechanical heart into Gerard Langevin in an three-hour operation Nov. 23. Officials at the McGill University Health Centre say the device, which is about the size of a flashlight battery, could last up to 10 years. That is longer than other models which are thought to be good for only two or three years.


The new mechanical heart, which is powered by batteries located in pouches on Langevin's body, provides a continuous flow of blood so the patient has no pulse.


"Mr. Langevin happens to be the only individual currently living in Canada without a pulse and without a measurable blood pressure," Cecere said Wednesday.


Langevin admitted to reporters that, before the operation, he felt his time was up after he suffered his second heart attack in July.


He had the other in 2002.


"I was finished. . . I had no time left. . . I probably had only a few months left to live," Langevin said.


He admitted he was afraid and hesitant about having the implant.


"My wife pushed me a lot to have the operation and I don't regret it."


Langevin, who comes from Coteau-du-Lac, southwest of Montreal, added it was "better than staying out for the count."


Dr. Nadia Giannetti, director of the MUHC's heart transplant program, said Langevin was deemed an unsuitable candidate for a heart transplant because of other medical conditions.


"Previously, we would have had little to offer and his heart would have continued to deteriorate," she said.


Giannetti said the entire procedure cost $100,000, with the tab being picked up by the hospital foundation.


The "Heartmate II" is currently part of a clinical trial at several hospitals in Canada and the United States.


Only one other Canadian hospital-the Toronto General Hospital-was invited to take part in the study.


The device has yet to be approved for use in either country.


Doctors says Langevin is well enough to be released from hospital in the coming days.

I am very skinny after breastfeeding my son & cannot seem to gain any weight. Could it be a loss of appetite from the pain meds? I have never really been a great eater & don't feel much different as far as appetite, but was still wondering if that may be a contributing factor in my not being able to gain weight.
