Aqueous Solution Definition in Chemistry

Aqueous Solution Definition in Chemistry Aqueous solution definition: An aqueous solution is any solution in which water (H2O) is the solvent.  In a chemical equation, the symbol (aq) follows a species name to indicate it is in aqueous solution. For example, dissolving salt in water has the chemical reaction: NaCl(s) → Na(aq) Cl-(aq) Although water is often called the universal solvent, it dissolves only substances that are hydrophilic in nature. Examples of hydrophilic molecules include acids, bases, and many salts. Substances that are hydrophobic do not dissolve well in water and tend not to form aqueous solutions. Examples include many organic molecules, including fats and oils. When electrolytes (e.g., NaCl, KCl) dissolve in water, the ions allow the solution to conduct electricity. Nonelectrolytes like sugar also dissolve in water, but the molecule remains intact and the solution is not conductive. Aqueous Solution Examples Cola, saltwater, rain, acid solutions, base solutions, and salt solutions are examples of aqueous solutions.   Examples of solutions that are not aqueous solutions include any liquid that does not contain water. Vegetable oil, toluene, acetone, carbon tetrachloride, and solutions made using these solvents are not aqueous solutions. Similarly, if a mixture contains water but no solute dissolves in the water as a solvent, an aqueous solution is not formed. For example, mixing sand and water does not produce an aqueous solution.

Dui Bu Qi, Saying Sorry in Mandarin Chinese

Dui Bu Qi, Saying Sorry in Mandarin Chinese There are many ways to say â€Å"sorry† in Mandarin Chinese, but one of the most common and versatile phrases is ââ€" ºduà ¬ bu qÇ . It means sorry in the sense that you have wronged someone and want to apologize. The phrase consists of three characters in traditional Chinese: Ã¥ ¯ ¹Ã¤ ¸ Ã¨ µ · (Ã¥ ° Ã¤ ¸ Ã¨ µ ·. Dui Bu Qi Ã¥ ¯ ¹ (duà ¬) in this case means to face, but in other situations means many other things, such as correct or to.ä ¸  (bà ¹) is a negative particle that can be translated as no or not.è µ · (qÇ ) literally means to rise,† but is often used in an extended meaning to be able to. If you put these together, you get something like unable to face, which is the feeling you have when you have wronged someone. This phrase in Chinese can function as a standalone way of saying sorry, but it can also be used as a verb, so you can say: 我å ¯ ¹Ã¤ ¸ Ã¨ µ ·Ã¤ ½   wÇ’ duà ¬buqÇ  nÇ . I have wronged you. Lets look at a few more examples. As you will see, offering an apology is often just a way of being polite, just like saying sorry is in English. ââ€" ºDuà ¬ bu qÇ , wÇ’ gÄ i zÇ’u le.Ã¥ ° Ã¤ ¸ Ã¨ µ ·, 我è © ²Ã¨ µ °Ã¤ ºâ€ Ã¥ ¯ ¹Ã¤ ¸ Ã¨ µ ·, 我è ¯ ¥Ã¨ µ °Ã¤ ºâ€ Sorry, I have to go now.ââ€" ºRà º guÇ’ wÇ’ shuÃ…  duà ¬ bu qÇ , nÇ  shà ¬ fÇ’u jià ¹ huà ¬ yun ling wÇ’?Ã¥ ¦â€šÃ¦Å¾Å"我è ª ªÃ¥ ° Ã¤ ¸ Ã¨ µ ·, ä ½  Ã¦Ëœ ¯Ã¥  ¦Ã¥ ° ±Ã¦Å"Æ'原è «â€™Ã¦Ë†â€˜?Ã¥ ¦â€šÃ¦Å¾Å"我è ¯ ´Ã¥ ¯ ¹Ã¤ ¸ Ã¨ µ ·, ä ½  Ã¦Ëœ ¯Ã¥  ¦Ã¥ ° ±Ã¤ ¼Å¡Ã¥Å½Å¸Ã¨ °â€¦Ã¦Ë†â€˜?If I say I’m sorry, will you be able to forgive me? It should be mentioned that there are other ways of interpreting or breaking down this phrase. You could also think of it as Ã¥ ¯ ¹ meaning to treat or correct, which would give the sense that you have not treated someone the right way or that you have done them wrong. For practical purposes, it matters little which phrase you use. Pick whichever explanation you find easiest to memorize. -Edited by Olle Linge

Architecture And The Everyday - Essay Example Thus, although politics dictated a small budgetary allowance for the construction of a large building and current design practices place a great deal of emphasis on the engineering rather than the aesthetics of a particular work, the architects of the Jubilee Library in Brighton were able to mesh all of these concepts with a design that served the common man and his need for aesthetic beauty, proving Upton’s point that the everyday architecture should not be and perhaps cannot be separated from the concepts of aesthetic Architecture as a serious venture. The library can be seen to strongly grasp the importance of showing the structure in engineering and materials used as it proudly displays its support columns, glass and tile curtain walls and concrete slab supports. It meets with the budgetary constraints of the political powers that be in its use of inexpensive and locally acquired materials even as it focuses attention on the need to create ‘Green Architecture' that r educes the building's impact on the environment through a variety of means that also function to reduce the cost of daily operation. Yet, even as it accomplishes all of these feats, it remains an aesthetically beautiful building that inspires the creativity and the imaginative use of the structure by the local population, encouraging thought and reflection by its simple existence and meeting the requirements of the more aesthetically minded Architects in their need for adhering to theory, philosophy and the principles of design.

The Community Nursing Practice Model - Assignment Example This theory takes a wholesome approach to nursing. It aims at ensuring that the health needs of the community members are fulfilled in the best way. It emphasizes access to primary care, and ensures that the values of primary health care get to be met satisfactorily. This model can be utilized in actual practice to promote the health of diverse community members. The values used in the model help in providing care that can lead to a decrease in many health concerns. These could include an increase in the community mortality rates, following greater access to health care, and treating the community members in a caring manner. More to these, the model helps in promoting the well-being of the community, through provision of quality advice. This includes advice on better eating habits that lead to a reduction in the cases of malnutrition (Barry & Lynn, 2011, p. 22). A brief nursing situation and possible significance of the theory or an aspect of the theory in the situation This model allows care to be granted in various institutions, such as schools. Therefore, schoolchildren get to access prompt health care while still in school. This serves a number of advantages to those connected to the child. First, the child receives immediate treatment, thus reducing the seriousness of the presupposed illness. This saves the student enough school time, hence ensuring that the student does not miss their studies for a long duration of time.

Toyota hybrid cars - Assignment Example Various advanced technologies that are utilized by hybrids include regenerative braking which is characterised by the electric motor applying resistance to the drivetrain consequently forcing the wheels to slow down (Fuhs, 2009, p. 73). In response, the energy form the wheels will turn the motor that acts as a generator which converts energy that usually goes to waste during braking into electricity and battery is used for storing the electricity until when it will be required by the motor (Lagunoff, 2008, p. 156). Another technology that is used by the hybrid vehicles is the electric motor assist where the electric motor avails more power to help the engine during acceleration, overtaking or going up a hill. Therefore, a smaller and more efficient engine can be used while in some of the cars, only the motor avails power needed for driving in low speed conditions where internal combustion engines are not very effective. They also employ automatic start and shut off that shuts of the engine spontaneously when the car pulls to a halt and starts it again it when the motorist presses on the accelerator. The automatic start and shut off is important in preventing wastage of energy from idling. Toyota is a leading corporation in manufacturing, assembling as well as supply of cars all over the globe. One of the key reasons for the company’s good performance is the efficient management system that it employs (Czinkota and Ronkainen, 2013, p. 535). There are several other striking attributes that have enabled the company to achieve its place as a market leader. The type of market structure that the company functions in cannot be defined clearly and in some cases, it is considered to be a monopoly. The dominance of the company in the market is what makes the company to be seen as operating a monopoly. The company’s differentiation approach has enabled it to have a monopolistic existence particularly in the emerging nations. Conversely, the

Ethical Issues Working with Youth

Ethical Issues Working with Youth To what extent can researchers plan for ethical issues when working with children and young people? People often think of ethics or morals, as a rule for distinguishing between what is right and wrong. Something that springs to mind, is the saying; Do unto others as you would have them do unto you or the religious creed of the Ten Commandments, Thou Shalt not kill. This is a common way of defining ethics and the norms for conduct that distinguish between unacceptable and acceptable behaviour. Most people learn ethical norms within the home, at school or in other educational settings. Majority of people acquire their sense of right and wrong during their childhood as moral development occurs throughout life. Simply because as human beings, we pass through different stages of growth as we mature. Ethical norms can be classed as ubiquitous, simply because one might be tempted to regard them as simple commonsense. A plausible explanation of these disagreements is that as humans, we can recognise some common ethical norms, but majority of individuals may apply and interpret these norms in different ways in respect of their own life experiences and own values. Our society has legal rules that govern behaviour, but ethical norms can be broader and more informal than laws. However, most societies use laws to enforce moral standards and ethical and legal rules use similar concepts, it is however crucial to point out that law and ethics are not the same. For example, an action could be classed as legal, but illegal or unethical, but ethical. Society also uses ethical concepts and principles to interpret laws, evaluate and criticise. Within the last century, citizens were urged to disobey laws in order to protest what they classed as unjust laws that were immoral. Within research with children and young people there are several reasons why it is important to adhere to ethical norms. Firstly, it promotes the aims of research and examples include, truth, avoidance and knowledge such as misrepresenting research data promote the truth, prohibitions against fabricating, falsifying and avoid error. Second, is that research often involves a great deal of cooperation and coordination amongst different people in different institutions and disciplines. Ethical standards promote the values that are essential to collaborative work, which include fairness, trust, accountability and mutual respect. For example, many ethical norms in research, such as guidelines for authorship, data protection policies, and confidentiality rules are designed to protect intellectual property interests, but still encouraging collaboration amongst the institutions. Therefore, researchers want to receive credit for their work and contributions to be disclosed prematurely and do not want to have their ideas stolen. Third and the main standard is that many of the ethical norms help to ensure that researchers can be held accountable to the public. Many of the norms with research are that it promotes a variety of other important moral and social values, for example social responsibility, human rights, compliance with the law, and health and safety. Critically, ethical lapses in research can significantly harm humans, students and the public. A researcher who may fabricate data in a clinical trial could harm patients and a researcher who fails to abide by regulations and guidelines, as set out in the ethical standards, could jeopardise his health and safety or the health and safety of staff and students in relation to radiation or biological safety. Consequently, ethics are often a matter of trying to find a balance between opposite extremes. Ethical research with children has changed significantly in the past 30 years and modern standards of research ethic may considerably depend on modern transparent research methods and a respectful relationship between children and researchers. During the 1947s lawyers stressed the dangers of research and insisted that willing consent should be obtained, although it was presumed that children were too young to give consent and consequently banned from participating from research. Traditionally, children were not allowed to consent for themselves for medical Children traditionally were not allowed to consent for themselves in terms of medical procedures and even for the simplest procedures. Today, there are three approved models of consent for children. First, children who are classed as competent, which are sometimes called minors may provide consent on their own. Second, children may provide an assent with parental consent and third, some children, due to their developmental stage or age cannot provide consent until parental consent is sought. Critically, this can raise serious ongoing challenges and some of the difficulties can arise from assessing competence, best interests as well as, motivations. As well as dealing with conflict between children, parents and or with children and youth, many of which may be living on the street or in a crisis situation, to name just a few examples. Children are traditionally considered more vulnerable than adults and this is because of their lack of competence to take part in making decisions. This could be especially around complex issues, such as health care and inclusion, in research. This vulnerability means that parents/ guardians, educators and health care professionals must be trusted to act in their best interests and make decisions for them. Moreover, this vulnerability has often meant that some children are simply excluded from research which is often in short-sighted attempts to protect them from harm. Consequently, this has resulted in excluding children from research and in research, failed to learn about children and to develop better and new ways to treat, approach and protect them. Alderson (2004) states that Ethicists teach the rules for ethical research are based on three main ways of thinking about what is good research: the principles of doing good research because it is right and correct thing to do. Rights based research involves respect and childrens rights, such as providing for basic needs for example, healthcare and education. Protection from child abuse and discrimination and participation is vital during ethical research in having their own views listened to and respected by adults. This is based on good research, rather then relying wholly on adult principles and values. The best outcomes based ethics basically means, working out how to avoid or reduce harm and costs. Researchers may produce very misleading results that are produced in policies that could damage childrens lives. Researchers may upset children by worrying them by making false promises or betray them. Critically, moral questions about power, honesty and respecting people can arise throughout the research process. Although a problem, often seldom mentioned by ethicists, is a risk on published research reports that increase stigma and disadvantage children and young adults. However, these reports can help researchers address such risks and problems and learn how to deal with them. An actual research that wasnt properly planned and a particular ethical issue uncovered was when, as stated by Dennis, 2009 A Japanese graduate student, was translating at a parent/teacher conference and the teacher asked her to pass along comments to the parents that Hanakos thought were rude. She did not want to do it. She intervened covertly because she did not pass along the comments as they had been expressed by the teacher, but she pretended to do so. She tried to make the point the teacher was making, but in a much more polite, positive, and from Hanakos perspective, acceptable way. Critically, this issue would have failed to demonstrate the teachers irritation and pose an ethical risk, as this interpersonal intervention was not inclusive. It could pose a potential harm, as it failed to promote moral and social values and follow ethical standards that promote the values that are crucial to collaborative work, such as mutual respect and trust, especially when working with child ren and young people. Another actual research that the researcher planned well for ethical issues was that off, Naz Rassool. Rassool (2004) was interested in working with a group of 14 and 15 year olds that raised several ethical and practical issues. Rassool felt that the pupils should not be exploited emotionally due to the nature of the work as the pupils were in a critical phase of their development. The research had to be very sensitive through its investigations of identity formation. Therefore, the ethical issues were paramount and persisted throughout the research. Rassool found the most effective way to address the theoretical research question to the pupils, incorporating the concepts of religion, knowledgeability, social change and individual reflexivity, all provided Rassool the theoretical framework. To generate a common understanding of the purpose of the research, Rossool conducted a seminar with staff involved, which addressed the aims of the research, ethical issues and the purpose of the activities. Other ethical issues, revolved in receiving parental consent and whether this as absolutely necessary, if the activities formed a part of the teaching programme. However, since the ultimate aim is to answer research questions it is crucial that all ethical issues are applied throughout. Critically, however when working with children and young people, it is normal protocol to seek parental consent, especially when conducting research. Rossools research promoted the aims of research; followed ethical standards and promote the values, which are essential for collaborative work, such as mutual respect, trust and fairness. It promoted moral and social values. Research heavily relies on the public to take part in the research and if this cooperation is to continue, then researchers have to keep high ethical standards. Alderson (2004) states public anxiety about the removal of childrens organs without consent, partly for research shows how research ethics, consent and rights may change, especially when children are involved. Similar changes may occur in social research and therefore, it is crucial to gain foresight about social research from the hindsight of medical research. Critically many medical journals refuse to publish these reports that may not have the backing of ethical committee approval and therefore, researchers need to keep abreast of the ethical standards. Gaining ethics committee approval can take time and can protect people who take part in the research and protect them from litigation and criticism. The extent researchers can plan for ethical issue is by involving children and young people and should only be conducted when the research question posed is crucial to the well-being and health of children. Ethics help researchers to be more aware of hidden problems, but do not always provide the right and easy answers. However, a research procedure which is not intended directly to benefit the child subject is not necessarily either unethical or illegal. Such research includes observing and measuring normal development and the use of healthy volunteers in controlled experiments. The participation of children is indispensable and this is because the information available from research on other individuals cannot answer the question posed in relation to the children. Therefore, the study method is appropriate for children and the circumstances in which the research is conducted, provides for the emotional, physical, emotional and safety of the child. The challenges relating to ethical and consent issues involving children and young people in research are numerous and require careful consideration and yet are not insurmountable. Critically, as a priority, researchers must engage with the legal, moral and ethical imperatives offered by UNICEF. As Alderson quoted, that Rights based research involves respect and childrens rights and as part of the UN Convention on the Rights of the Child in particular. The researcher needs to give diligence to Article 12, and the article due and diligent consideration in its entirety, by respecting the views of the child. Researchers must not only commit to inclusive practices, but also maintain assiduousness in ensuring that children and young people are respected participants in the research process, from selection of methodologies to the dissemination and reporting of results. With these guidelines in mind, children should be offered opportunities to genuinely participate in research. When adults are making decisions that affect children, children have the right to say what they think should happen and have their opinions taken into account. Ethical considerations are paramount in childrens research and management of these considerations can be very influential on the research that is ultimately completed with children and young people. The major issues discussed include, protection and safety versus participation, the role of ethics committees and the impact of consent processes. In summary, negotiating ethics approval and access to children and young people remains a major challenge. More attention needs to be given to facilitating information and understanding participatory research across all groups involved to minimise culture clashes and increase the understanding of the nature of participatory research. As Dennis, 2009 quotes There is one ethical principle that worked differently: all peoples voices should be included in decision making thus those who oppose egalitarianism should not be allowed to make decisions that limit the inclusion of others voices. In this case, there is no way to achieve egalitarian inclusivity with people who would limit the egalitarian and inclusive treatment of others. Thus, the two aspects of this ethical principle do not contradict each other and do not need to be criticised on these grounds. The extent researchers can plan for ethical issue is by ensuring the adoption of methods which are respectful to the children and is also crucial that researchers take ethics seriously. This may mean researchers moving away from traditions that in the past may have considered children as unthinking human beings. Instead, it places the emphasis on respecting children as dynamic people, which makes this method more realistic and productive. This is consequently classed as ethical, as most ethics encourage research methods with children participants. Word Count: /2,500

The State of Solar Power Policy And Incentives in Vermont Essay

The State of Solar Power Policy And Incentives in Vermont Vermont has become widely known as a progressive, even cutting-edge state in terms of its public policy. With two out of three of its Congressional delegation officially independent, a groundbreaking civil-unions law, and no fast-food franchises in its state capitol, perhaps that reputation is well-deserved. Energy; its generation, transmission, usage, and impacts upon the Earth, has arisen as a tempestuous, geo-political issue in the past few decades. As the petroleum era explodes (or should we say implodes?), the development and utilization of renewable energy sources has become vitally important for the survival of humanity and all the other species on our shared Earth. So then, how is the tiny green state of Vermont doing in terms of the development of solar energy, one of the central tenets of the renewable energy movement? What policies exist to help direct its agencies and organizations? What financial incentives are in place to encourage a homeowner to invest in solar techno logy and design? In one year, the equivalent of over 5 million kilowatt hours of solar energy hits each acre in Vt. (Vt. Solar Energy Guide, 1993) How well is the government of Vermont motivating people to stick something in front of all that energy? The main agency entrusted with renewable energy in Vt. is the Dept. of Public Service (D.P.S.) formerly headed up by Richard Sedano, now run by Davis O’Brien. This office works with many of the other groups in the state that push for the use of more solar power and other renewable energy sources. From the D.P.S. website we can read former governor Dean’s official Energy Initiative (Dec. 2001): It â€Å"is a long-term vision for Vermont that looks ... ...nd people wanting to help. Although there could always be more money waved around to persuade more people to invest in solar, the state of Vermont seems to be taking forward-thinking, yet cautious, stand in support of renewable energy.
