Business Psychology - Essay Example It is imperative that one recognizes his need to get professional aid; only after such recognition can he truly accept his own condition, whereas a resolution to the problem might immediately be made. The approach of the consultant can greatly affect the connection between the patient and the doctor. Trust, as well as high opinion toward the counselor must be immediately established---and maintained. It can be concluded that the relationship lies on the hands of the expertise of the specialist. Psychologists are specialists in human behaviour, development and functioning. They have expertise in conducting research and applying research findings in order to reduce distress, address behaviour and psychological problems, and to promote mental health and rational behaviour in individuals and groups. In the provision of mental health services (either public or private) psychologists vary in terms of the services they provide, their level and type of postgraduate training, and also their degree of clinical experience and/or specialisation. Becoming a registered psychologist requires 4 years undergraduate study, followed by either 2 years of supervised experience with a registered psychologist or completion of a postgraduate clinical masters or doctoral degree in clinical psychology. Clinical psychologists (i.e. those who have completed the postgraduate clinical qualifications) also have to spend some time working under the supervision of another clinical psychologist. In order to practice, all psychologists must be registered with the Psychologist Registration Board in their state or territory. Furthermore, the Australian Psychological Society (APS) is the national professional body for psychologists. Membership of this society ensures a high level of professional and educational competency. The APS also provides a

Sphalerite Essay Example | Topics and Well Written Essays - 1250 words

Sphalerite - Essay Example As sphalerite is soft and fragile it is mostly best left unset as collectors or museum pieces. Gem-quality material is usually a yellowish to honey brown, red to orange, or green There are a number of ways sphalerite is formed; bacteria also play a role in its formation. In the regions where there is low oxygen solution such as flooded tunnels the bacteria's take in zinc and sulfur from the water and combine them to create a byproduct of sphalerite known as sulfide, which reacts with the metals including zinc creating insoluble products. This build up of microbial precipitation by the bacteria have led to the discovery of large zinc sulfide deposits by the miners. The biofilm formed is grey in color and is further developed naturally to form sphalerite. Sphalerite is a cubic crystal with zinc and sulfur atoms tetrahedrally coordinated. This structure is similar to that of diamond. The hexagonal analogue is known as wurtzite structure. The lattice constant for zinc sulfide in the zincblende crystal structure is 0.596 nm, calculated from geometry and ionic radii of 0.074nm (zinc) and 0.184nm (sulfide). It forms ABCABC layers. Sphalerite is obtained from underground mining. ... It forms ABCABC layers. Mining Sphalerite is obtained from underground mining. It is the ore of zinc that is formed in veins which are layers of rocks and minerals formed underground. It is found in sedimentary, igneous and metamorphic rocks. Sphalarite accumulates in deposits which can extend far underground. Thus underground mining is most suitable; other methods would be too expensive and difficult. The underground excavation is determined by strip ratio method which is the total amount of waste materials that need to be removed in proportion the amount of ore. Thus minimum possible waste is extracted. The underground mine of sphalerite consist of sophisticated network of tunnels, shafts and equipments. It is entered through a shaft, a horizontal tunnel or an adit which is a horizontal entry way. There are several levels in the underground mine and sphalerite in mined in rooms called stopes. It is drilled and blasted out taking care of the ceiling so that the mine does not collapse. Sphalarite mining process involves a number of equipments. Continuous mining machines are used which cut through rocks and pull them up, even separating the unusable ore from waste rock all in one system. Dump trucks are used in the mine to carry material to appropriate locations to different parts of the mine. At times shuttle cars are also used. Today in the modern era mining is a highly technological and mechanized process. Sophisticated vehicles, rail systems and state-of-the-art drilling systems are bought from manufacturers and suppliers. Ventilation systems pump in fresh air while removing poisonous gases and dust. Also, the roof is supported by timber, concrete or even steel supports. Steel rods are
