The difference between embryonic stem cells and adult stem cells is that the embryonic stem cells are pluripotent stem cells that are from the inner cell mass of the blastocyst. Adult stem cells are undifferentiated cells and are found throughout the body. The adult stem cells are multiplied by cell division to replenish dying cells and revitalize damaged tissues. Totipotent cells are stem cells that are capable of giving rise to any type of cell or a full embryo. A pluripotent cell is a stem cell

ELECTRICAL CONDUCTORS A conductor is an object or type of material which permits the flow of electric charges in one or more directions. For example‚ a wire is an electrical conductor that can carry electricity along its length. Physics All conductors contain electrical charges‚ which will move when an electric potential difference (measured in volts) is applied across separate points on the material. This flow of charge (measured in amperes) is what is meant by electric current. In most

2.5 Aspects of Solar Cell Efficiency Most of the energy that reaches a cell in the form of sunlight is lost before it is converted to electricity. The usual efficiency of these systems ranges between 10% to 15%‚ though sometimes this efficiency increases to 30% and more. Certain physical properties affect the cell efficiency which we will briefly state. 1- Reflection: Studies show that untreated silicon reflects 36% or more of sunlight that strikes it. Chemically coating and texturing the surface

(A) Rules-based accounting standard Rule-based systems are fairly simplistic‚ consisting of little more than a set of if-then statements‚ but provide the basis for so-called "expert systems" which are widely used in many fields. The concept of an expert system is this: the knowledge of an expert is encoded into the rule set. When exposed to the same data‚ the expert system AI will perform in a similar manner to the expert. Rule-based systems are a relatively simple model that can be adapted to

brevis and longus muscles. The tendon of the abductor pollicis longus bifurcates with one part inserting on the metacarpal of the thumb and the other part inserting on the falciform bone‚ the tendon to the falciform bone is the larger of the two. Between the dorsal surface of the falciform bone and the palmar surface of scapholunate‚ there is an arthrodial joint. The falciform is connected to the styliform cartilage on the opposite side of the wrist by a
