The Molting Process for Insect Growth

The Molting Process for Insect Growth Molting,  known technically as ecdysis, is literally a period of growth for insects. In humans, an analogy can be drawn to molting as a period of personal transformation, such as the shedding of ones old self and the emergence of a new and improved person. Insects grow in increments. Each stage of growth ends with molting, the process of shedding and replacing the rigid exoskeleton. People often think molting is the simple act of an insect breaking out of its skin and leaving it behind. In truth, the process is complex and involves several parts. When Insects Molt After egg hatches, the immature insect feeds and grows. Its exoskeleton is like a shell. Eventually, the larva or nymph must shed its unyielding overcoat to continue its development. The exoskeleton which serves as its  external backbone is used for protection and support. Without an  exoskeleton, the insect could not survive. An old exoskeleton is shed when a new one is ready underneath, a process that can take days or weeks. Understanding the Exoskeleton To understand how molting occurs, it helps to know the three layers of the insect exoskeleton. The outermost layer is called the cuticle. The cuticle protects the insect against physical injury and water loss, as well as provides rigidity for muscle. It is this outermost layer that sheds during a molt. Underneath the cuticle is the epidermis. It is responsible for secreting a new cuticle when it is time to shed the old one. Underneath the epidermis is the basement membrane. This membrane is what separates the insect’s main body from its exoskeleton. The Process of Molting In molting, the epidermis separates from the outermost cuticle. Then, the epidermis forms a protective layer around itself  and secretes chemicals that break down the insides of the old cuticle. That protective layer becomes part of the new cuticle. When the epidermis has formed the new cuticle, muscular contractions and air intake cause the insect’s body to swell, thus splitting open the remains of the old cuticle. Finally, the new cuticle hardens. The bug squeezes out from the outgrown exoskeleton. The insect must continue to swell and expand the new cuticle, so it is large enough to allow room for more growth. The new overcoat is soft and much paler than the former one, but over a few hours, it becomes darker and begins to harden. Within a few days, the insect appears to be a slightly larger copy of its former self. Pros and Cons of Molting For some insects, a  big benefit to having a system of molting for growth is that it allows damaged tissue and missing limbs to be  regenerated  or substantially reformed. Complete regeneration may require a series of molts, the stump becoming a little larger with each molt until it is a normal or nearly back to normal size. A  major disadvantage to having to molt  as a system of growth is that the animal in question is entirely incapacitated during the process. An insect is completely vulnerable to a predator attack while undergoing molting.

The form of writing is very complex to write, there are a lot of lines and curves you must write in order to write one word in Chinese. It is even hard to pronounce the Chinese words because some words can sound the same but also mean something completely different. The numbers ancient Chinese people used were not the ones we use in our western civilization, the numbers even looks like the words except t he number of lines drawn to show the number is a lot less. There are actually two types of Chinese characters, the first is the way to pronounce the word itself and this form of Chinese writing is a lot similar to the western civilization’s way of the alphabet. The other form of Chinese writing is the words itself, the words are written very differently then in the western civilizations.

Management of Quality Essay Example | Topics and Well Written Essays - 1500 words

Management of Quality - Essay Example This compelled the organization to reinforce the quality of the process that every step. A consultant was hired who recommended the use of bespoke quality management in the organization that will facilitate in incorporating major quality improvement programs (Nobel 2011; Kuballa 2007; Kanji 1995). This was a top down approach in which the significant projects were identified and were controlled by trained team. It is quite significant for the senior management to implement bespoke quality management system with instructive and constructive quality management that allows the employees to contribute towards the improvement of the organizational functions. Quality management should not be procedural like for instance the ideas that are brought by the employees should be turned down by the managers. In the top down approach of quality management, the effort made towards the quality development is cascaded down to other levels of the organization. In the top down approach of quality manag ement the senior level managers are only involved. The top down approach has certain advantages that are discussed below: In the top down approach the senior management is involved, which signifies quality management is a time taking process and senior management will be aware of it. This will make the availability of time and financial resources for the process. Any changes in the organization require proper mentoring from the senior officials. In this method the employees will get proper monitoring from the higher officials. Figure 1: Top down Approach Sources: (Author’s Creation) However, this method is not free from limitations. The primary limitation in this method is: Unnecessary delay is caused if the senior officials are not fully operational related to the changes in the quality management required. Enhancing the quality process requires use of different techniques and tools. It also requires interaction of the top management with the middle management on an everyday basis, which is unrealistic, and counterproductive (Schiller, Kovach and Miller 1994). The employees who are directly dealing with the process are seen to possess better knowledge as compared to the members of the top management. Thus, they can implement the quality changes better. Quality management system was implemented by the organization in the second stage. It is the system in which both the quality objectives and policies required to achieve those objectives are decided (Williams and Buswell 2003). The main advantage of this system is that it involves the officials of the top management and the employees from every level. This signifies the involvement of all the people from different levels of the organization. The problems in this system is that it requires a high amount of effort and documentation, often focuses on third party certification rather than business improvement and hinders business if it is self-fulfilling (OECD 2001). Figure 2: Quality Management system Sourc e: (Author’s Creation) Answer 2: A Quality management system (QMS) is a management technique that is used to communicate with the employees regarding how they can produce the desired quality of services and products. Along with this, it also looks at influencing the employee action related to the quality specification in completion of the task. There are two types of quality managemen

Modelling of optical parameters for optimum collection of concentrated solar radiation for photovoltaic devices - Dissertation Example Much has been utilized from our important ecosystems such as the forests, fisheries, wetland, fresh water resources, and that we have to move fast and change our course of actions to save the environment and the planet as a whole. The world’s program of action has not improved these past decades because we still depend on fossil fuel; specifically eighty per cent of energy comes from fossil fuels. The threat posed by climate change and global warming is pushing mother Earth to its near end. Industrialisation, consumerism in America and globalisation, among other drivers of change, have pushed and motivated scientists to find ways to address environmental problems which have continued to plague humanity. Constructions of buildings, new inventions and new technologies, have become a race for supremacy among big international organisations. Environmental problems of the world today have been worsened by technology. But we can use technology to save the environment. Fossil fuels a nd coal can be depleted. There will come a time that we’ll lack resources for these forms of energy source. In other words, there must be a way to produce a substitute for fossil fuels and coal, something that is not harmful to the ozone layers and the environment as a whole. Solar energy and other forms of environmentally friendly energy using the wind, the tidal waves, hydro, and other similar forms, must be tapped. The DESERTEC website says that a few hours the earth receives power from the sun is equivalent to a year it can use for its requirements to run factories, industries, businesses, homes, and offices. The deserts of Africa and Arabia can absorb much heat from the sun using mirrors to heat water to produce steam and convert this into energy. With this technology, solar energy is convertible into High Voltage DC current; the technology uses AC current converted into Direct Current using gargantuan transformers and components that store electric currents like capacit ors. (Desertec Foundation, 2009) This paper aims to provide studies and research on solar radiation and how to ‘catch’ the rays of the sun to provide electricity. With this, we focus on what seems to be an emerging, but is quite becoming popular, technology – photovoltaic concentrator

Employment Law for Human Resource Practice Essay

Employment Law for Human Resource Practice - Essay Example Employment Law for Human Resource Practice James Franklin’s attributes of attendance problems to a cavalier attitude of employees of Millennial Generation is discriminatory based on age. Any action directed to this group of staff will, therefore, be viewed to carry a discriminatory intent tailored to punish a particular group of personnel. Every employee has a contract with the employer whether written or not. Employers are legally obliged to furnish their employees with statements of terms and conditions of engagement. Changing the terms of engagement without the employee’s agreement as did Happy Valley Incorporation is an outright breach of contract (Walsh, 2016). After the enactment of the new attendance policy, it was not communicated to all employees but one, Mr. Allen who did not share with the rest beside being directed only to a faction group of employees. Second, they did not seek the employees on the best ways to deal with the attendance problem. Large forms such as Happy Valley Incorporation must inform and consult employees or their representatives, in this case, P.O.O before making significant changes or redundancies. Even in the absence of this requirement, it is a prudent and ethical business practice to keep employees informed and involved in major decisions affecting them. P.O.O has two alternatives of justice to pursue, Consultation with the Happy Valley Management and seeking a legal redress.

Racial and Ethnic Stereotypes Essay Example for Free

Racial and Ethnic Stereotypes Essay People being indiscriminate based on partial and inexact information by sources as television, cartoons or even comic books This is a description that seems to go against many public standards. The above words are the exact description of stereotypes. Stereotypes as implicit from the description, goes mostly hand in hand with media only not the standard meaning of the blameless media we know. Media propaganda is the other form of media that is somewhat described as media treatment. In this paper, the subsequent will be discussed: first, how stereotypes of ethnic groups operate in propaganda, why does it function so satisfactorily, and finally, the consequences of these stereotypes on the life of Egyptians in particular in society. A fair inspection will be conducted on this example of stereotypes through clarification examples and research consequences from researches conducted from reliable sources. The real association between Egyptians’ stereotypes and propaganda discussed in this paper shall magnify the suggestion of stereotypes and propaganda in common. It seems essential for this paper to start with some clarification of the circumstances related with propaganda. Propaganda can be thought of as a foster parent for stereotypes. Propaganda is recognized to be the planned manipulation of public opinion through concealed messages in advertisements and other media functions. Thus, propaganda uses numerous techniques to be able to consign theses hidden messages to the public and influence their view. Fear, brainwashing, name calling, glittering generality, misinformation and much more are some of the ways that propaganda uses to persuade and manipulate the opinions of the masses. Propaganda finds the usefulness of stereotypes in the fact that it’s easy, quick and direct to the public. In the case of stereotypes about ethnic groups, Egyptians in this case are being portrayed as uneducated, unethical, ignorant, desert animal raisers, terrorists and uncultured ethnic group. These name calling and misinformation techniques are what propagandists use to contrive the society to portray Egyptians as humans of the underworld and Egypt as a deserted country that hunger and ill health are its residents. The preceding are all stereotypes that are propagandas of the media to convince such generality into truth and facts. Racial stereotypes particularly function usually through propaganda of the media, due to the improbability of every man travelling to every country, with the technique of ‘misinformation’ through movies, shows, and news reports. Egyptians have been stereotyped as desert residents for many years regardless of the reality and actual state of Egypt as a country. For instance, the stereotypes pointing that Egyptians are mostly uneducated due to their ignorance of the importance of education is proven false by studies of trustworthy sources. Among those studies, the one conducted by the American university in Cairo, Egypt. Al-Ahram weekly, a credible newspaper known all across the Arab world, has posted in its October issue of 1998 the following: â€Å"According to Sahar El-Tawila, the essential researcher on the team, interviews conducted with girls and boys nationwide demonstrate convincingly that work and marriage were rarely stated by boys and girls respectively as reasons for departing school†¦ These may be options for those who have already left school, but they are not the impetus behind their decision to leave† (Al-Ahram 1998). Therefore, according to an American research, Egyptians are not uneducated conceited nation. After all, there is at least an American University known worldwide built in Cairo where many Egyptians have gotten their Bachelors, Masters and PhD’s from. Still, the media has successfully manipulated the public opinion to reason Egyptians as desert wonderers. Now that the first concern, of how such Egyptian-bashing stereotypes work in propaganda, has been discussed, an interesting question then must be asked: how did it come about so successfully for the public of North America to view Egyptians in such state of mind? Media being a powerful information source to the majority of North Americans, and sometimes the only source of information about specific ethnic groups, has the ability to convince the public viewpoints and opinions. Of course with stereotypes powered by propaganda in movies is very thriving in view of that American films are the most favored and appreciated media function. Openly, in one of the movie reviews now on a review website about the movie â€Å"The Mummy† which takes place in Egypt from start to end, the subsequent sentence was stated: â€Å"The Mummy is a lot of fun. So the story is unsophisticated and the characters are all stereotypes (particularly the Egyptians, who are either noble desert warriors or smelly illiterate pig-things). Who cares? The special effects are truly spectacular. † (Jennifer Mellerick, 1999). Easily, stereotypes are even expected by who understands them and the media propaganda generates more and more. To attest that such depiction is a stereotype and not fact, the website ‘Egypt WWW Index’ has a list of all universities in Egypt (an estimated thirty educational institutions in total), many links to political and governmental committees and services, business, commercial, and entertainment facilities, as well as links to political women figures in the Egyptian society. More than the average North American could even imagine of Egypt , and it is all owed to the media propaganda that produced this image of Egyptians.

GPS Safety Bubble Technology Essay -- Safety Bubble Technology

Although Global Positioning technology has existed since the mid 1970’s, some of the most significant advancements have taken place within the last five years. In recent months, studies have been conducted by NASA and other institutions concerning the use of advanced GPS technology in both computer controlled flight of commercial aircraft and the establishment of â€Å"no-fly safety bubbles† around designated areas and buildings. In essence an aircraft’s computer system would override a manual command and not allow the craft to enter these designated areas. There are many possible benefits of this technology, but with any new advancement also comes ethical questions. While some believe this technology will increase air travel safety, others argue that misuse of this technology could lead to disaster and loss of life. The use of Global Positioning System navigation technology was established in the early 1970’s, long before the idea of a GPS â€Å"safely bubble† existed. Up to this time the required satellite technology to support global positioning systems had not been developed. In 1978 the first GPS satellite was launched (Rand McNally). It took nearly fifteen years to perfect GPS for public use, but since this has happened, land navigation has been revolutionized. GPS was initially developed by the Department of Defense for primarily military uses, but has since been made available to the general public. In 1996 the National Security Council published the following goals for the GPS system: †¢ To strengthen and maintain national security. †¢ To encourage acceptance and integration of GPS into peaceful civil, commercial and scientific applications worldwide. †¢ To encourage private sector investment in and use of U.S. GP... ...tation advances the common good, promotes a safe society for citizens, and helps to ensure the freedom of the American people. We have a duty to use modern technology such as advanced GPS systems to achieve these aforementioned goals. It is clear that despite the risks, this technology is needed and should be developed and installed on all aircraft. References: Haskens, Shelly. â€Å"Security Now Their Domain† The Huntsville Times.
