Chemical Reactions And Energy Changes - 1712 Words

Theory: It is stated that all chemical reactions involve energy changes. Where a substance is stored with chemical energy and has the potential to be converted to heat. Exothermic and Endothermic reactions are included in the changes in heat of energy. As Exothermic reactions release heat, and transfer the temperature to its surroundings. This is because the energy absorbed to split the bonds of the reactants release less heat energy than the product made by the bonds. An endothermic reaction however absorbs heat from its surrounding as the reactant doesn’t supply enough energy therefore it absorbs energy from its environment. In addition, endothermic reactions release more heat energy in order to break the bonds made by the products. The bonds in the exothermic and endothermic occur during the experiment, as the breaking and making of the chemical bonds are involved. Exothermic is energy that is released when any chemical bond is formed and Endothermic is energy which must be added when a chemical bond is broken. It is recognized that with exothermic reactions, the products will contain a lower energy with the reactants. Endothermic reactions however have products which contain a higher energy than the reactants. This is because exothermic reactions release heat, and in the progress contain less energy with the products. As opposed to Endothermic reactions, where it absorbs the energy, bringing the products to a greater number. Activity A and C are expected to have anShow MoreRelatedChemical Reactions Of Energy And How It Changes Essay938 Words   |  4 Pages Thermochemistry deals with energy and how it changes.

Why Was Italy Not Unified After the Congress of Vienna...

Before the Congress of Vienna the French occupation had far reaching affects on Italy. The power of the Church and the Pope was reduced, changes were made in landownership and land was redistributed. A new middle class began to appear. Agriculture was improved and the peasants were freed from their old feudal ties and obligations. Then when Napoleon was defeated and the restoration of the old regime and monarchs was started, Italy again became a country divided into eleven independent states, excluding the tiny principalities and the Republic of San Marino. So Italy was not unified after the Congress of Vienna due to a number of reasons, such as the foreign influence of the Central European Powers, parochialism within the states, the lack†¦show more content†¦The lay people had no part in government, apart from a few lay members of advisory bodies called ‘congregations. Politically, Italy was fragmented. Further, half the states were governed by kings or dukes who alread y occupied or hoped soon to inherit the thrones of the non-Italian countries. Venice and Piedmont had dominions outside Italy. The Papacy had worldwide ecclesiastal concerns. The peninsula was not merely divided; the boundaries and interests of its states ignored its natural frontiers. Equally, there still survived three ancient republics of importance: Venice, ruling a considerable empire on the eastern shores of the Adriatic and a large territory, known as the Veneto, on the mainland of Italy; Genoa, which until 1768 governed the island of Corsica; and Lucca. After the Papal States there were five significant duchies. Of these members of the Austrian royal House of Habsburg, Milan direct from Vienna, and Tuscany, ruled the two most important separately. The Duchy of Parma and Piacenza was under a Spanish Bourbon, but could not be united either with Spain or with Naples and Sicily. The Duke of Modena and the Duchess of Massa and Carrara represented Italian dynasties. So the foreign influence of the Central European Powers both before and after the congress of Vienna was major a factor in Italys remaining as eleven independent states rather than becoming united.

MIS Security and Ethical Issues

Question: Discuss about the MIS Security and Ethical Issues. Answer: Introduction Here I will discuss ethical dilemma of ICT that is encountered in our organization XY Pvt. Ltd. It is a software development company and we deal in different types of software solutions. Our company is an international company and selling its products worldwide. Our customers are satisfying with our services. Every customer is careful about its personal information or credit card information that is used by our company to keep records for customers purchasing. Our company XY Pvt. Ltd. is doing all its efforts to provide appropriate security and privacy to its potential customers and it is aware about common ethical issues of ICT. An ethical dilemma is also faced by our business organization and due to this we lost some essential business information (Infosectoday.com, 2017). In this segment we will discuss about ethical dilemma in detail that is encountered by our organization. In XY Pvt. Ltd., most of the business information and customers information is stored in online databases through companys website. This website is also used for taking customers order and to advertise our business. The database of this website stores lots of important and confidential information in it such as billing and shipping information, credit card information, purchasing records etc. Therefore, various modifications and insertions are done in database by different departments of our organization. To successfully handle frequent usage of a business website, it is necessary to apply high level security and privacy to this website. But it is not done by our technical experts and a big issue of improper security maintenance of website occurred. The issues of improper authentication and virus attacks have commonly observed by users of this website. By Doing Ethics Technique (D ET) we can discuss this ethical dilemma in an effective way. Doing Ethics Technique According to above analysis, we got to know that current big issue is related to insecurity of companys website and the main reason of this insecurity is use of improper validation techniques that causes chances of hacking attacks. Besides this, other main issue is of malware and virus attacks that can put bad influence on overall working of website and heavy loss of important information can occur. The main reason of this issue is inappropriate usage of antivirus and its regular updates (Ecommerce.hostip.info, 2017). The major fact of above discussed ethical dilemma in our business organization is lower performance of database and due to this overall process of data access has become time consuming. According to analysis of technical experts it is found that due to virus attack, performance of database system is getting worst. The validation processes for login credentials does not work properly and users are using weak passwords for login that are easy to hack by hackers (kusmulyono, 2017). Ethical and Non-Ethical Issues On the behalf of available information about XYZ Pvt. Ltd. the major ethical issue is irresponsible behavior of employees towards security of database that contains confidential information. The employees in business organization do not log-off their accounts properly after using it and unauthorized users try to access their accounts to collect important information. Besides this problem other problem is that employees do not use anti-virus solutions to protect their systems from viruses. Due to this, virus occurrences on system easily, when any new thing is downloading from database. Antivirus solutions scan every new entity to identify virus in it and fix bugs (Acm.org, 2017). But lack in use of anti-virus enhances chances of virus attacks on databases and systems. If we talk about non-ethical issues, then violation and not use of organizations security policies by employees are considered non-ethical acts (Computerworld, 2017). Due to above discussed ethical and non-ethical issues, management, senior and junior level employees will be effected. The main reason for this is ethical and non-ethical issues will bring some new changes in overall processes of organization and it may not be accepted by all business employees (Tutorialspoint.com, 2017). Ethical Issues and Suggestions The main ethical issue of XY Pvt. Ltd. Company is poor maintenance of security and resources of organization. To resolve these issues, support of technical department of company is required, so that they can improve deficiencies of database security by developing strong validation processes for login credentials. Besides this, issues of virus attacks can be resolved by using advanced anti-virus solutions. Every security policy and procedures should be strictly followed by all associated members of company (Edewor, 2017). For resolution of above discussed ethical issues of XY Pvt. Ltd. are listed as below: Prevention of database and system from unauthorized access. Use of secure online channels for communication, e.g: Secure Socket Layer (SSL). Use backup and restore options to get prevention from data loss. Use of advanced anti-virus solutions to get rid of virus attacks. What is the Best Option? Above listed all options can provide high level security to database, computer systems and networks. But proper implementation of these options is very much necessary. Among above listed options the best option is to use secure network connection by using SSL. If network will be secured then it is easier to control problems of unauthorized access, hacking and phishing attacks etc. Therefore, I would suggest our organization to use this option to control security and privacy issues (Sina, 2017). After this whole discussion we can say that above discussed ethical issues of security and privacy of databases are common for all business organizations. So it will be better to give preference to implementation of above listed solutions at workplaces. References Ecommerce.hostip.info, (2017).

Zen Interior Design Essay Example

Zen Interior Design Essay Zen Interior Design is a way of designing a space through meditative concepts in an attempt of giving the space a feel of enlightenment. The definition of this design is ambiguous compared to the other discipline in Interior Design. According to Shaolin-Wahnam Institute (n.d., para 1) Zen basically means â€Å"meditation†. Meditation promotes flow of energy which is translated into space with Zen Interior Design. Over all design emulates a mind who is in an enlightened state, clearing it from the unnecessary load giving it harmony. The design strategy is to conform a space in such a way that it would be like a concrete picture of a mind will look like when it reaches a harmonious state. Origin Zen design was developed in China and spread into Japan in the twelfth century it gave its name to a style of Japanese architecture that was based in one of China’s dynasty called Song; the earliest recorded Zen design architecture was Jizodo Shokofuji (1404). Such influence came to existence because at that time the wide use of Zen Buddhism was rampant. If you would study the culture of Japan, Zen Buddhism is embedded everywhere.

Feng Shui follows certain rules and principles that are sometimes thought of as practical solutions in order to keep the correct ch’i of the space. In Zen, the ultimate purpose of design is meditation that results in harmony and balance. Feng Shui aims to correct the living conditions in order to promote physical and psychological well-being to the dweller.   (Marie T., Feng Shui simplified, para 3) Design Techniques Zen in Interior designing has no standard rule. Design is being done in the context of harmony. Its application is limitless in terms of space; it can be done for a whole house. An isolated room or even a space in you work area. It can be applied through the choice of color palette, space management and space use. All of this can be done be keeping it to what is just essential and natural. That is why Zen is often affiliated with the minimalist design. Colors are kept natural and limited, trying to keep it as light and as close to nature as possible. Strong colors must be kept at bay and everything that can be seen should be relaxing to the eye. Spaces ought to be open and free, up to the point that the designer should induce the illusion of it. Strategically placing mirrors and windows that will help spread light is one of the known strategies to achieve this. Allowing the space to be simple and close to its use is another technique often applied in this type of design. (Applying Ze n to Interior Decorating, para 1) Modern Developments Zen design is currently widely used in the industry of Interior Design. It was again largely noticed in the recent years entering 21st century. In residential homes it is simply not utilized for its beauty and charm but it gives the dweller a personal space as their own sanctuary, from today’s common busy lifestyle. (Mcevoy, Interior Design Style, para 5). Not only that, today’s housing especially in most of the South East Asian are getting smaller. With this kind of design on these houses a lot of issues can be addressed. Dwellers will be comfortably situated in their houses even if space is limited. The business sector benefits from this as well. Their commercial and industrial facilities, adapt some of its design because its parameters contribute to a lot of things like efficiency of flow in a workspace and improvement of or working environment. To them it affects the worker’s psyche which entails operation cost reduction, which is has a great impact to businesses. References: Anonymous. (n.d.).
