Main Group Elements Definition

Main Group Elements Definition In chemistry and physics, the main group elements are any of the chemical elements belonging to the s and p blocks of the periodic table. The s-block elements are group 1 (alkali metals) and group 2 (alkaline earth metals). The p-block elements are groups 13-18 (basic metals, metalloids, nonmetals, halogens, and noble gases). The s-block elements usually have one oxidation state (1 for group 1 and 2 for group 2). The p-block elements may have more than one oxidation state, but when this happens, the most common oxidation states are separated by two units. Specific examples of main group elements include helium, lithium, boron, carbon, nitrogen, oxygen, fluorine, and neon. Significance of the Main Group Elements The main group elements, along with a few light transition metals, are the most abundant elements in the universe, solar system, and on Earth. For this reason, main group elements are sometimes known as representative elements. Elements That Arent in the Main Group Traditionally, the d-block elements have not been considered to be main group elements. In other words, the transition metals in the middle of the periodic table and the lanthanides and actinides below the main body of the table are not main group elements. Some scientists do not include hydrogen as a main group element. Some scientists believe zinc, cadmium, and mercury should be included as main group elements. Others believe group 3 elements should be added to the group. Arguments may be made for including the lanthanides and actinides, based on their oxidation states. Sources King, R. Bruce (1995).

Free Essays on Roman Gods

The ancient Romand worshiped many gods, godesses and spirits, each of whom was responsible for a different part of life. Juno was the goddess of woman; Jupiter, the king of the gods was also the god of the sky; Mercury was the god of merchants; Wulcan the god of fire; Mars the god of war; Minerva the goddess of wisdom; Venus the goddess of fertility and love. The ancient Romans adopted gods and goddesses from other cultures as well. Bacchusor or Dionysus, the Greek god of wine; Cybelle, the Turkish goddess of motherhood; and Isis from the Egyptian pantheon who was concerned with reincarnation. Emperors and empresses were sometimes worshiped after their deaths. Emperors showed their devotion to their favored deities by building temples to them. Roman citizens left offerings such as food, milk, wine, money, jewels or statues at temple alters and engaged in ceremonies and animal sacrifices to win the gods approval. The Romans were generally accepting of other people’s religions but persecuted the Christians because, among other things, they displeased the gods by refusing to patricipate in such animal sacrifices and unjust ceremonies. Christianity finally because the official religion during the 4th century in Rome. The Romans built large temples for these many gods. They were often built in places that people believed were special to their gods. The Acropolis, in Greece is one of these places. In ancient Greece, the Greeksk alson believed in many gods and goddesses. The gods behaved much like ordinary people, but they had great wisdon. They were wiser, more cunning, and more powerful.

Processing of Pre-MicroRNA to MicroRNA Research Paper

Processing of Pre-MicroRNA to MicroRNA - Research Paper Example Thus, the paper will also discuss the five activities of the processing of pre-MicroRNA into MicroRNA (Grosshans & Slack, 2002, pp.17-19). In the study involving photogenic elements, scientists normally use samples from animals before testing their results on human beings. In most biochemical laborites, one would find mice especially the Drosophila, Arabidopsis, and elegans type. These animals provide some useful biochemical samples, which scientists study to inform on certain biological and biochemical issues. Just like human beings, mice also have microRNA. Through cloning and sequencing, scientists extract microRNA for study purposes. Various studies have shown that both human beings and mice have over two hundred to three hundred inimitable microRNA genes. The studies also explain that in organisms, human beings and mice included, microRNAs are homologous in nature. Consequently, this is a clear indication that microRNAs play significant roles by representing comparatively old and essential regulatory pathways (Gallo et al., 2006, pp.6156-6159). As seen above, the genome hosts pre-MicroRNA and other photogenic elements. Within the genome, sequence encoding of microRNA takes place. However, since there are mechanisms that control microRNA expression, the encoding of microRNA will involve only known genes. In most cases, these genes occur in various flimsy locations within the human chromosomes, and one of the chief characteristic about them their independently transcription shape. It is imperative to note that the primary microRNA transcripts (pre-microRNA) are the ones that encode strands of microRNA. In general, such encoding produces the microRNAs that have the same orientation as pre-microRNA. Clearly, this is an indication that there is a microRNA promoter, which is responsible for such transcriptions. In most cases, the genome stores microRNA genes, and here, these genes appear in form of cluster.

Nike Case Study Research Paper Example | Topics and Well Written Essays - 750 words

Nike Case Study - Research Paper Example Ballinger was passionate that a company should have a responsibility for its workers even if they are the lowest paid workforce of the company (Spar, 2002). Ballinger was assigned to monitor labor conditions in an Indonesian plant by overseas American companies because he considered that the reason for international companies to prepare a setup in poor countries is to exploit the low-wage labors. This has been true over years that big multinational companies have been shifting their operations to lower wage countries in order to reduce their production cost and collect more profits. The cost of production in America is double the cost of a product which is being manufactured in other countries (Locke, 2002). He claims that Nike has a policy that in order to produce cost effective products, they mistreat their workers and make them work longer hours than required. He believed that even though there were laws for protecting the labor rights, Nike continuously fed the Indonesian governm ent with bribe to overlook their part of misdeed. Ballinger accused Nike that they knew people were dependent on the company and would rarely leave the company, so they mistreated them to get more production with fewer necessities and food provided to the people. Ballinger had strength in his arguments because workers were in a bad situation and when they were interviewed by Ballinger, they agreed with the same (Connor, 2001). Nike’s Response to Ballinger’s Allegations The first response from Nike was clear that their manager said Nike’s not responsible for the actions of their independent contractors. Nike considered that they are not involved in any kind of activity in Indonesia and most likely they would not be responsible for their act. However, Nike asked its public relation officer to draft a code of conduct for its independent contractors (Stoner, 2006). This code of conduct would then be sent to their new contractors in which all aspects of working condi tions of labors, environment regulation and insurance of their workers were addressed. Nike wanted all of their suppliers and independent contractors to agree with all terms that were specified before making any further deal. It was made mandatory that these suppliers would have to give their written consent of their honesty and non-discrimination (Spar, 2002). Nike hired an accounting firm Ernst & Young to conduct an audit of its overseas factories. Auditing would inform Nike with activities of their overseas factories and would identify their problems. But the problem started to mount and criticism had started to rise again with a greater force. Nike denied any act of direct involvement in child labor activity and of worker exploitation. In Washington, Nike was the first company to join Apparel Industry Partnership (AIP) which was aimed to develop reformed labor standards in foreign factories. Nike also included a new department in its company which was known as Labor Practices De partment which role was to monitor labor practices in premises of the factory (Spar, 2002). Recommendations Firstly, Nike should focus on improving its processes in their overseas factories by making strict guidelines and norms for their factories to follow. The company shall motivate their independent
