Technological, Designs & Art Developments Assignment

Technological, Designs & Art Developments - Assignment Example Art is an aspect that is intertwined with culture and traditions and as culture and traditions changed towards civilization so did art. Significant inventions in history changed the approached towards art as artists sought to embrace emerging technologies to be able to portray their art more effectively while at the same time improving on aesthetics. According to Kleiner (2010), developments in art have always occurred roughly during similar periods in history as developments in other fields such as science, philosophy and politics. Therefore, the general realization is that art is an aspect that is intertwined with developments in other areas due to the need for artists to respond to these developments either by critiquing or seeking to highlight important aspects of these developments. The following timeline project will conduct an analysis on the developments in art and design from the 15th to the 20th century with a specific emphasis on four genres. The four genres of focus will be sculptures, drawings, paintings and architecture. The timeline has revealed that art was significantly influenced by historical periods and advancements in the fields of science, politics and philosophy. Moving from the Gothic era to the modernism era, there is the realization that art is a significant part of the society and that art responds to societal changes. During the Gothic era when the Catholic Church significantly influenced most aspects of life, art basically responded to this influence by concentrating on religious designs. The renaissance art on the other hand sought detachment from the church and sculptures could be evident in streets. Baroque art was significant in introducing the use of oil paints. During the enlightenment era, the Catholic Church sought to regain its popularity through art but in vain due to the protestant influences. The Romantic era depicted art not as it is but as it ought to be with regard

He comments that the concepts of high-context and low-context cultures and polychronic (i.e. multitasking) versus monochronic time (i.e. one thing at a time) orientation are useful, but ambiguous. The next theory comes from Hofstede’s cultural dimensions. These dimensions pertain to: power distance, individualism /collectivism, masculinity/femininity and uncertainty avoidance (Dahl 12). Dahl commends the model for its simplicity and widespread application on different cultural interactions. Dahl also explains Trompenaars and Hampden-Turner’s seven value orientations. These orientations are: universalism versus particularism; communitarianism versus individualism; neutral versus emotional; defuse versus specific cultures; achievement versus ascription; human-time relationship and; human-nature relationship (Dahl 14). Dahl explains the connections between these orientations and other intercultural theories. In addition, Dahl describes Shalom Schwartz’s Schwartz Value Inventory (SVI). SVI has two categories: individual-level analysis and cultural-level analysis. Dahl concludes that there is no one theory of cultural dimensions. In the article, â€Å"What Do Employers Really Want? Top Skills and Values Employers Seek from Job-Seekers,† Randall S. Hansen and Katharine Hansen discuss the major skills and values that employers desire from their employees. They want to help job-seekers become more employable for target employers by explaining these skills and values and how the latter can appear in resumes, cover letters, and interviews. Hansen and Hansen discuss that the top main skills that employers want from employees are: communication skills, analytical/research skills, technical literacy, flexibility, interpersonal abilities, leadership and management skills, multicultural sensitivity, planning and organizing skills, problem-solving/reasoning/creativity skills, and teamwork

The Corrosion Of Metals Engineering Essay

The Corrosion Of Metals Engineering Essay Each year, billions of dollars are spent on repairing and preventing the damage of metal parts caused by corrosion, the electrochemical deterioration of metals. The majority of metallic materials in a practical context are generally exposed to corrosion in both atmospheric and aqueous environments. Metallic corrosion has become a global problem which has negatively affected the industrialised society; hence why it has been studied in such comprehension since the beginning of the industrial revolution in the late eighteenth century. Corrosion also affects the average daily life both directly, as it affects the commonly used service possessions and indirectly, as producers and suppliers of goods and services incur corrosion costs, which they pass on to consumers. (ASM International, 2012). The effects of corrosion are distinctively recognized on automobile parts, charcoal grills and metal tools all of which will have a depleted efficiency once corroded. This corrosion may result in con tamination which then poses health risks. For example, the pollution due to escaping product from corroded equipment or due to a corrosion product itself. As a result of these consequences, corrosion prevention has been studied in great depth. Corrosion of various metals may be prevented by applying a coating of paint, lacquer, grease of a less active metal to keep out air and moisture. These coatings will continue to suppress the effects of coating so long as they stay intact. Examples of metals that are heavily protected in the industrial world are iron and aluminium. Vast quantities of the ores or each metal are mined and processed each year using large scale chemical reactions to produce metals of the purity required for their end use. For this report, the chemistry involved in the corrosion of both iron and aluminium will be researched as well as the methods employed to prevent their corrosion. Justification as to why corrosion happens will be explained with reference to physic al and chemical properties, electrochemistry, equilibrium, rates of reaction, enthalpy and solubility at every point where it is appropriate. Before explaining why corrosion happens, it is important to define corrosion in terms of electrochemical processes. An electrochemical reaction is defined as a chemical reaction involving the transfer of electrons through redox. Corrosion is a broad and complex subject that can be examined in three different categories; electrochemical corrosion, galvanic corrosion and electrolytic corrosion. In all forms of corrosion, three components must be present an anode, a cathode, a metallic path for electrons to flow through, and an electrolyte for the ions to flow through. Both the anode and the cathode must be in contact with the electrolyte to allow the ions to flow. As well as this, oxygen and hydrogen must also be available, either directly or as a result of chemical action and the resultant dissociation of water into its two constituents. In this report, electrochemical will be investigated in terms of its spontaneous nature and self-sustainability. Firstly, spontaneity is dependent on the sign of free energy. Gibbs free energy can be defined by the following equation:; where is the enthalpy, is entropy and is the temperature in kelvins. When is negative, the reaction will occur spontaneously (Zhang, H. 2012). For this to occur the entropy must increase and the enthalpy must decrease. This can be proven as a system of spontaneity aims towards disorder which directly coincides with entropy. Also, the change in enthalpy must be negative as thermal energy will be released from the energy stored within chemical bonds in a spontaneous system. Furthermore, in this electrochemical procedure, the negative electrode is the cathode and the positive electrode is the anode. Note that metals are used as they are good conductors of electric current due to the specific ionic bonding which then allows the electrons to be delocalized and move relatively freely. When these two electrodes are connected by a wire, free electrons flow through the wire from the anode to the cathode forming an electric current. Both the anode and cathode are submerged in separate substances respective to the elements of both electrodes from which the positive ions are attracted to the anode and the negative electrons are attracted to the cathode. The anode atoms are being oxidised as they are losing electrons and forming positive ions which then dissolves into solution. This results in a loss of overall quantity of zinc metal. In practical terms, this could be considered the pitting of the corrosion process which can be defined as a form of extremely local ized corrosion that leads to the creation of small holes in the metal (ASM International, 1987). Electrons formed at the anode travel to the cathode where they combine with the positive ions in solution to turn into the respective metal. Therefore the cathodic ions in solution are being reduced as they are gaining electrons. This production of extra cathode metal can be compared with rust which is a reddish- or yellowish-brown flaky coating of iron oxide that is formed on a metal by redox reactions. With just this in mind, the electric current would flow for only a limited time as the anode would have a build-up of positive ions being formed. While at the cathode increased amounts of electrons are being pumped into it. The result is an excessive positive charge that builds up at the anode that attracts electrons (negative) and prevents them moving away. While at the cathode the negative build up repels the electrons. As a consequence of this build-up of charge, no electron flow occurs and the cell eventually fails (Dynamic Science, 2012). Note that a solution cannot have a full charge and only a partial charge. To negate this issue, a salt bridge is used which contains ions that complete the circuit by moving freely from the bridge to the half cells. The substance that is placed into the salt bridge is usually an inert electrolyte whose ions are neither involved in any electrochemical change nor do they react chemically with the electrolytes in the two half-cells (IIT, 2012). As well as completing the circuit, it ensures that the charge between the two half cells remains electrically neutral. It does this by passing negative ions into the anodic half-cell where there shall be an accumulation of extra positive ions due to oxidation resulting in a slightly positive charge. Similarly, an accumulation of negative ions will exist in the cathodic half-cell due to the deposition of positive ions by reduction. Electrical neutralization is once again achieved by the salt bridge providing positive ions to the cathodic substance. Thus, the salt bridge maintains electrical neutrality. IRON CORROSION Only a few metals, such as copper, gold and platinum occur naturally in their elemental forms. Most metals occur in nature as oxides in ores, combined with some unusable metal like clay or silica. Ores must be processed to get the pure metals out of them, and there are nearly as many different processes for this purpose as there are metals. The process, as well as the elements present, greatly influences the properties of the metal. An important characteristic of metals is the extremely significant effect that very small amounts of other elements can have upon their properties. The huge difference in properties resulting from a small amount of carbon allowed with iron to make steel is an example of this. Taking into consideration the amount of iron that is used globally, the effect of corrosion on iron alone requires millions of dollars each year. The problem with iron as well as many other metals is that the oxide formed by oxidation does not firmly adhere to the surface of the meta l and flakes off easily causing pitting (KKC, 2012). Extensive pitting eventually causes structural weakness and disintegration of the metal. The iron oxide acts as a sacrificial anode which is a stronger reducing agent than iron that is oxides instead of the protected metal. Therefore it can be said that it acts as the anode. Since the oxide does not firmly adhere, it does little to protect the iron metal. As mentioned, iron in contact with moisture and air (oxygen) is corroded by a redox reaction. The anode reaction can be expressed as an oxidation of iron atoms: Both water and oxygen are required for the next sequence of reactions. The iron ions are further oxidized to form ferric ions (iron ) ions. This can be written as: These electrons are then conducted through the metal and are used to reduce atmospheric oxygen to hydroxide at another region of the iron. Therefore the cathodic reaction is: Considering that iron atoms dissolve at the anodic sides to form pits and ions which diffuse toward the cathodic sites; ions are formed at cathodic sites diffuse toward the anodic sites. Iron (II) hydroxide forms in a random location between the cathode and the anode which is then oxidised by atmospheric oxygen to iron (III) hydroxide. This can be expressed by: From here, the iron (III) hydroxide is then gradually converted to rust otherwise known as hydrated iron (III) oxide: ; Where generally equals 3. The formation of rust does not have a designated position as it can occur at random away from the actual pitting or corrosion of iron. A possible explanation of this is that the electrons produced in the initial oxidation of iron be electrically conducted through the metal and the iron ions can diffuse through the water layer to another position on the metal surface which is available to the atmospheric oxygen (KKC, 2012). Also, points of stress, such as where the piece of metal has been shaped, are more active than unstressed regions and thus act as anodic sites. The electric current between the anodic and cathodic sites is completed by ion migration; thus, the presence of electrolytes increases the rate of corrosion by hastening this mitigation. Therefore it is evident that the corrosion of iron can be directly related to a voltaic cell and can both be defined as electrochemical cells due to their spontaneous nature. ALUMINIUM CORROSION Similar to Iron, aluminium is also susceptible to electrochemical corrosion when exposed to moister. Aluminium, both in its pure state and allow, is truly a remarkable metal as it is light, tough, strong and readily worked by all common processes. Unlike iron however, It has excellent resistant to corrosion in the marine environment, and it requires little maintenance. The fundamental reactions of the corrosion of aluminium in aqueous medium have been the subject of many studies. In simplified terms, the oxidation of aluminium in water proceeds according to the equation (ELSIVIER, 2012): This specific reaction is balanced by a simultaneous reduction reaction, similar to iron, in ions available in the solution which then consumes the oxidised electrons. In an aqueous solution such as fresh water, seawater or moisture, thermodynamic considerations can be used to represent only two possible reduction reactions that can occur. The other occurring reaction is the reduction of oxygen dissolved in the moisture: Quite similar to the corrosion of iron, the aluminium atoms dissolve at the anodic sites to once again form pits and which diffuse toward the cathodic sites while ions are formed at the cathodic sites and diffuse toward the anodic sites. Therefore: ; Where generally equals 3. Although aluminium is still susceptible to corrosion, the metal itself is very resistive. Aluminium alloys generally have excellent resistance to atmospheric corrosion; require no protective coatings or maintenance beyond cleaning, which aids greatly in preventing unsightly pitting where dirt or salt accumulate. When aluminium is exposed to oxygen, it forms an oxide surface film that protects it from corrosive attack. The oxide acts as a sacrificial anode which is a stronger reducing agent than aluminium. It is then oxidised instead of the protected aluminium metal, serving as the anode. For the most part, damage due to atmospheric corrosion is pretty much limited to fairly slightly pitting of the surface with no significant loss of material or strength. Duration of exposure is an important consideration in aluminium allows, the rate of corrosion decreases with time to a low steady rate regardless of the type of allow or the specific environment. Thus corrosion of both aluminium and iron can both be defined as electrochemical processes which are similar in nature but have different protection potentials. PROTECTION METHODS Corrosion avoidance begins in the design process. Although corrosion concerns may ultimately reduce structural integrity, they should be a consideration to decrease money loss. Good maintenance practices are another way of avoiding corrosion, such as rinsing away salt water or avoid standing water. Corrosion protection systems, for the most part, are designed to control corrosion, not necessarily eliminate it. The primary goal is to reduce the rate of corrosion by having the smallest possible current. Current is defined as the flow of charge, or electrons, per time through a conductor hence. Since corrosion is the movement of electrons through redox, it can be quantified using this equation which represents the corrosion reaction per time or the corrosion rate. To do this, two efficient protection methods are available: cathodic protection systems and coatings. All cathodic protection schemes operate on the basis of the voltaic corrosion process, so like voltaic corrosion; cathodic protection systems require an anode, a cathode, an electrical connection and an electrolyte. Cathodic protection will not reduce the corrosion rate if any of these four things are missing. The basis of this protection method depends on the difference in corrosion potentials between the two metals immersed in the same electrolyte. This causes electrons to flow from the metal with the higher activity and negative potential (anode) to the metal with less activity and negative potential (cathode). This flow of electrons continues until the two metals are at the same potential, that is, there is equilibrium between the voltages. Electrode potential is a measure of the tendency for a material to be reduced e.g. accepts electrons. Also, activity is a measure of how easily a metal will give up electrons. Thus, the more active a metal is, the more negative the electrode p otential. This principle, directly relates to the two types of cathodic protection systems: sacrificial anode systems called passive protection and impressed current systems also known as active protection. Sacrificial anode systems are simple, require little but regular maintenance, and have low installation costs. We intentionally add a metal to the circuit to supply the electrons to the cathode. When metals are in a voltaic couple, the difference in there negative potentials causes the anodic metal to corrode and release metallic ions into the electrolyte. The more negativity in the corrosion potential means it will be a stronger reducing agent and will more readily give away electrons thus corroding first. Since the more negative metal in the closed circuit corrodes first, we can control corrosion by simply adding to the circuit a metal that possess two necessary characteristics: a corrosion potential more negative than the metal that is being protected, it is expendable which is not essential to the operation of any particular system. Therefore when a metal possessing these characteristics is made the anode, corrosion is controlled. The impressed-current type of cathodic protection system depends on an external source of direct current. Alternating current cannot be used since the protected metal would likewise be alternating, between anodic and cathodic. Basically, the anode is immersed in the electrolyte is connected to one side of a DC power supply and the metal to be protected is connected to the other side. The voltaic current flow is detected and measure against a reference electrode. If unfavourable, current flow is adjusted automatically by the power supply control system to compensate. Due to the high currents involved in many seawater systems, it is not uncommon to use impressed current systems in marine situations. Impressed current systems use anodes (ICCP anode) of a type that are not easily dissolved into metallic ions, but rather sustain an alternative reaction, oxidization of the dissolved chloride ions (Deepwater, 2012). Advantages of this cathodic protection are that they can develop so much higher voltages than sacrificial anode systems, so they can either push current through lower conductivity electrolytes or through longer distances. Disadvantages include the possibility of over protecting certain metals. This can cause hydrogen embrittlement in high strength steels. In aluminium specifically, accelerated corrosion can occur of the very structure that is being protected. Therefore it is evident that this form of cathodic protection, although more complex, poses some reliable advantages as well as some detrimental disadvantages.

Compaction of Concrete

Consolidation of plastic concrete is termed as compaction. In the process of compaction, efforts are only directed to reduce the voids in the compacted concrete. Compaction of concrete can be done either manually or mechanically. When it is done manually it is called hand compaction or tamping, and in second case it is termed as machine compaction. ?Hand compaction: Hand compaction is done with the help of steel tamping rods, or timber screeds. Marrow and deep members are compacted with tamping rods. Thin slabs and floors are tamped with the help of screeds.Compaction should be done in layers of 30 cm for mass concrete and 15 cm for reinforced concrete. Companction should be carried out for such a time that a layer of mortar starts appearing at the compacted surface. Excessive compaction and under compaction both are harmful for concrete. Due to excessive compaction, C. A. particles sink to the bottom and cement and F. A. mortar appears at the top. This makes concrete structure heter ogeneous, and hence affects strength. This method of curing is adopted in the case of precast members.It has been noticed that by keeping the wet conditions, if temperature is increased, the rate of increase of strength also increases. This enables concrete to acquire its full strength within short period and hence, curing is also finished within short period. ?Machine compaction: Machine or mechanical compaction of concrete is done with the help of vibrators. Vibrators produce vibrations which when transmitted to plastic concrete make it to flow and affect compaction. The air bubbles are forced out of concrete due to vibrations. Over vibration should not be allowed, otherwise C.A. particles will concentrate at the lower layers and mortar will come to the surface. There are three types of vibrators in most common use: †¢Internal vibrator: This vibrator is also known as immersion, poker, or needle vibrator. It consists of a power unit and a long flexible tube at the end of which a vibrating head is attached. This vibrator develops about 7000 vibrations per minute. Wherever, compaction is to be done, the vibrating head is inserted in the concrete. This vibrator is very useful for compaction of mass concrete. †¢Form vibrator: This vibrator is clamped to he form-work and imparts vibrations to the concrete through form-work. This vibrator is used only if the use of internal vibrator is not practicable as in the case of thin and congested situations. It is also called external vibrator. †¢Surface vibrator: It is also named as screed or pan vibrator. It is clamped to the screed, it Imparts vibration to the concrete from the surface when screeding operation of the concrete is carried out. It is effective only for depths of about 20 cm and hence useful for thin horizontal surface such as pavements. Compaction of Concrete Consolidation of plastic concrete is termed as compaction.

Sex, Love and Conversation - 1102 Words

Deborah Tannen’s: Sex Lies and Conversation When in a relationship things can be very difficult, like in any other situation there are ups and downs. Deborah Tannen has set out to explain and try to justify the increasing divorce rates in America. Through many social realizations and scientific studies, Tannen is able to make a case on why the divorce rate has increased throughout out the years; Wives believe that their Husbands are no longer listening to them. Women have divorced their husbands more than ever because of communication problems. According to Tannen this is truly not the case overall, it is how men and women have been raised that keep them from being great communicators. Both men and women have their own ways of communicating; ways that they learned was socially acceptable throughout their lives. Men are the prime suspects in communication problem divorces; Tannen has analyzed why and understands the uprising. The main claim in this piece is that men are not lis tening to their wives, leading to divorce or break up’s. Tannen appeal to reasoning in her piece states that ever since growing up males and females have been separated by sex. This is a significant reason behind how men communicate versus how women communicate.

One similarity that Martin Luther King and Nelson†¦show more content†¦In other words, King motivates people to fight racial discrimination. This speech was given by him in 1963 in Washington, D.C. where about 250,000 people gathered. Similarly, In South Africa, Nelson Mandela fought for the freedom of blacks from apartheid. As mentioned in Peter Limbs book Nelson Mandela: A Biography, On June 26 (now commemorated as Freedom Day in South Africa), the main campaign began in earnest. Thousands of protesters challenged the rigid segregation of apartheid, entering restricted townships and whites-only service points at post offices and railway stations . . . Released on bail, Mandela resumed his coordinating role, traveling around the country explaining tactics, and encouraging firm but disciplined action (Limb 51). From this we observe that Mandela coordinated and led people to fight apartheid. As it can be concluded from the preceding information, Martin Luther Kings a ctions and Nelson Mandelas actions justify their similarity. Another similarity between King and Mandela is that they had the same beliefs. King firmly supported his nonviolence protest movement for the equality of blacks in America.
