What can two dollars buy you? A small coffee at Starbucks‚ a candy bar‚ bag of chips‚ and a soda‚ a slice of pizza. For nearly three billion people‚ approximately half of the world ’s population‚ two dollars a day is all the money that the person has to live on. Moreover‚ of the 2.2 billion children in the world‚ 1 billion grow up in poverty; 640 million without adequate shelter‚ 400 millions with no access to safe water‚ and 270 million with no access to health services (UNICEF 2005).

innovation. Ask the average person what they think the military is like‚ and you will get responses that conjure images of mindless robots‚ programmed to follow orders without question. The actual cultural norm is just the opposite and that goes from the top generals to brand new recruits in basic training. For those who have spent time in the military‚ the familiar mantra from day one is continuous improvement. Each branch of the service (Army‚ Navy ‚ Air Force‚ Marines‚ Coast Guard) has its own

I recently received the publisher’s proofs of an accessibility paper which will be published in the new year. The reviewers spotted a number of broken links in the references. Some of them were links to previous papers I had published‚ and the errors were introduced by the publisher (which I confirmed by checking the details of the paper which I submitted). But for a couple of other references the pages did seem to have disappeared. I contact Stuart Smith‚ one of the co-authors‚ and asked him if

QUESTION 1 Describe in detail‚ the simple changes in synapses that happen during classical conditioning. Discuss the extent to which all forms of learning can be explained by these simple synaptic synaptic changes. The brain’s ability to learn‚ to change in response to experience and to store/retrieve learning through memory it is a fascinating process fundamental to one’s existence. The first scientific study of animal learning demonstrated a form of associative learning - classical

FROG MUSCLE PHYSIOLOGY 2) What was the smallest voltage required to produce max contraction? What proportion of the muscle fibers in the muscle do you think were contracting to produce this maximal response? Muscle fibers act in response to isolated stimuli in an all or none fashion. However‚ a muscle organ‚ such as the gastrocnemius muscle‚ is composed of many individual muscle fibers. It is known that all of the fibers in a muscle do not have the same threshold and that a stimulus applied to

Animals have three types of muscles; skeletal‚ smooth‚ and cardiac. This lab however is only concerned with skeletal muscle. A special characteristic of skeletal muscle is their ability to contract or shorten via thin (actin) and thick (myosin) filaments (Flanagan‚2017). This gives a striated appearance which is a key distinguishing characteristic between other types of muscle (Flanagan‚2017). Skeletal muscle is also multinucleated. Skeletal muscle needs plentiful amounts of energy to be able to contract
