The Diary Of Anne Frank Essays - Anne Frank, Women In World War II
The Diary of Anne Frank Journeying back to the early nineteenth century, when Nazi forces occupied Germany during World War II, the lives of those living in this territory was spent in constant fear and anxiety. The Diary of Anne Frank leads readers through the harsh times of a family trying to escape imprisonment in concentration camps by Nazi soldiers, where death was almost certain. Born on June 12, 1929, Anne Frank was a German-Jewish teenager who was forced to go into hiding during the Holocaust. She and her family, along with four others, spent 25 months during World War II in an annex of rooms above her father's office in Amsterdam, the Netherlands. During the two years in hiding which Anne refers to as a time when the ideals are being shattered and destroyed, when the worst side of human nature predominates, when every one has come to doubt truth, justice and God (pg.327). Anne kept a diary that was given to her by her father, Otto Frank, on her birthday. Between June 1942 and August 1944, from Anne's thirteenth birthday until shortly after her fifteenth birthday, Anne recorded her feelings, her emotions, and her thoughts, as well as the events that happened to her. ...[I]deas, dreams, and cherished hopes rise within us only to meet the horrible truth and be shattered...yet in spite of everything I still believe that people are really good at heart (pg. 327). The diary is an accurate record of the way Anne grows up and matures, in the unfortunate situation she found herself. Given the circumstances in which the novel is written Anne gave a very vivid description of her surroundings and the feelings she encountered throughout her ordeal. The novel displays the grief and frustration that is experienced throughout the time spent in hiding. The emotions of the situation are captured in the text and gives validity to the pain and frustration encountered. Despite the amusing and enlightening side of the diary, that documents the process of her adolescence, it also provides a vividly terrifying description of what it was like to be Jewish hiding during the time the Nazis sought to kill all the Jews in Europe. After two years of living in the secret annex, behind a bookcase, and having to be extremely quite during the day so that the workers in the office and warehouse below could not hear them the family was captured. The betrayal of Anne and her family to the Nazis and their placement under arrest lead to their deportation to concentration camps. In an entry on August 1, 1944, Anne confides to her diary an analysis of her situation. She concludes that her behavior has been a front during her years in hiding to help her cope with the people surrounding her. Nine months after her arrest, Anne wrote that ...if only there were no other people in the world (pg.331). The writings give Anne's thought wishful pretense that if no one else were in the world, that the pain and suffering would end. Anne gives readers a sense of truth and honesty about her situation that allows the reader to experience her life as a stubborn, touchingly vulnerable teenager who one minute is in love with the world and the next detached. This book is an extraordinary piece of work written by a young woman finding her way in captivity. Anne was an immensely gifted writer and a person of great sensitivity. She shows her depth through emotions as well as by absolving the feeling of others and communicating them through writing. Anne's true personality is brought to life on every page and allows the reader to feel as though they actually know her. Whether enthralled in the heights of ecstasy over her budding fascination with Peter Van Dann, another teen hiding in the annex, or drowning in the depths of despair over her life in hiding, Anne would always confide her private thoughts and interest in her diary. Anne's vivid writing allows the reader to experience second hand what it was like to be a teenage Jewish girl confined to an inside world with little resources except necessities to survive. The detail in which her story is told gives light to the talents and emotions a young mind experienced as she deals with traumatic situations. For its insights into the life of a German-Jewish child living in Germany during Nazi occupation, The Diary of Anne Franks, offers a vivid, realistic view of how a family tries to

Effects on Obesity essays
Effects on Obesity essays In America today many people are suffering from obesity. Obesity is defined as enormous amount of weight caused by excessive accumulations of fat. Researchers of American Medical Association found that 56 percent of American adults are overweight and that 20 percent are obese. Obesity have great effects on human being such as their: medical condition, physical abilities, and mental effects. Medical condition is one of the main effects to people who are obese. For example Type 2 diabetes is a main disease that effects people who are obese. Study shows 73 percent out of all obese people have Type 2 diabetes. Next common disease that attacks people who are obese is cancer. For female they have high risk in breast cancer. Women who gain nearly 45 pounds or more after 18 are likely to develop breast cancer after menopause. Also people who are obese usually have high blood pressure that will lead them to shortage in life. At the end these diseases will kill people who are obese if ità ¡Ã ¯s untreated. Second, obesity will effect physical abilities. People who are suffering from obesity may not be able to do things that normal weight people can do. Playing sports or do any activities that involves fast movement of any kind is main physical ability that obese people canà ¡Ã ¯t do. They may not even have power to walk sometimes because of mass amount of weight pressuring down on their weak ankles which gives them enormous pain that will stop them from walking. They may not also have power to jump up and down. Ità ¡Ã ¯s hard for over weight people to jump up and down with their heavy weight. Finally, mental effects have played many negative roles in obesity. People who suffers from obesity goes through depression due to their over weight appearance. Most people who are obese have hard time fitting into groups because of their differences. Since the are obese they may not...

Art Appreciation- Principles of Design Essay Example | Topics and Well Written Essays - 750 words
Art Appreciation- Principles of Design - Essay Example Constable continued to study and copy the work of his predecessors for as long as he lived, constantly measuring their interpretations of the natural world against his own experience of it. His main interest was scenes from nature, despite earning money painting portraits for the rich. Although largely ignored by the English art community in his lifetime, Wilson (n.d.) reports ââ¬Å" The Hay Wain and View on the Stour near Dedham went to the Parisian dealer Arrowsmith in 1824 and created a lively, if short-lived, interest in France.â⬠Since his death the true value of Constableââ¬â¢s has been recognized by all of the art community. ââ¬ËStoke-by-Naylandââ¬â¢ is a dark figure emerging on a path from a shady forest on the right, with the village of Stoke-by-Nayland located on the right. A partially cloudy sky covers the right sky above the village with the left side having a smaller visible sky in proportion with the whole painting. The scale and proportion used allows Constable to make the forest seem in the forefront and the village farther away. The directional forces pull the eyes toward the figure and forest first. Even the brushstrokes seem to be coming from the right. The emphasis is on the mysterious forest. The subordination is the village in the background. The contrast between the colors is obvious with the white clouds and dark greens of the forest. The two most important principles are scale and proportion and contrasts. These two principles define ââ¬ËStoke-by-Naylandââ¬â¢. Constable uses scale and proportion to create a forefront nature scene with a figure emerging and a background village. Constable often used the technique common at the time of sketching actual nature scenes before going back to the studio to paint (Wilson n.d.). This would entail making the sketch using scale and proportion, and then transferring the scale and proportion onto a larger canvas. However Constable accomplished this, he did an

Business D1 Essay Example | Topics and Well Written Essays - 250 words
Business D1 - Essay Example Nevertheless, application of interpersonal skills is depends on communication, which is either formal or informal. Effectiveness of interpersonal skills is manifested through development of substantial communication capabilities. For instance, people are able to communicate freely, though without the knowledge of the messages that they are disseminating (Tracom Group, 2013). For instance, effective communication skills entail aspects such as maintenance of eye contact, control of physical twitches such as fidgeting and concentration, while listening during a conversation. In this case, an active listener is able to ask clarifying questions, which is an illustration of their effective interpersonal skills in terms of listening. Therefore, through this way they can ensure that the message is understood as it is being conveyed. Ineffective interpersonal skills can cause serious problems during a serious conversation, thereby leading to misunderstanding; in fact, this can also lead to conflicts (Tracom Group, 2013). For instance, in a situation where a business associate does not maintain eye contact during a conversation, this is an indication that they are not interested with the message conveyed; hence, this becomes

The Hydrogen Bond Essay Example | Topics and Well Written Essays - 500 words
The Hydrogen Bond - Essay Example The nature of the hydrogen bond in addition to some other factors, such as the disordered arrangement of hydrogen in water imparts unusual properties to H2O that have made conditions favorable for life on Earth. For example, it takes a relatively large amount of heat to raise water temperature one degree. This enables the world's water bodies to store enormous amounts of heat, producing a moderating effect on the world's climate, and it makes it difficult for marine organisms to destabilize the temperature of the ocean environment even as their metabolic processes produce enormous amounts of waste heat. One of the most important noncovalent interaction within molecules is the hydrogen bond, a dipole formed when a hydrogen atom covalently bonded to an electronegative atom is shared with a second electronegative atom (typically an oxygen, nitrogen or fluorine atom), such that the proton may be approached very closely by an unshared pair of electrons. Hydrogen bonds play a significant role in the unusual thermodynamic properties of water and ice, and the DNA double-helical and protein a-helical and b-structure conformations are extensively hydrogen bonded. Hydrogen Bonds can be formed between different molecules (Intermolecular) or between the different parts of the same molecule(Intramolecular).

Cooling Load Calculation Procedure Engineering Essay
Cooling Load Calculation Procedure Engineering Essay The total amount of heat energy that must be removed from a system by a cooling mechanism in a unit time, equal to the rate at which heat is generated by people, machinery, and processes, plus the net flow of heat into the system not associated with the cooling machinery. [1] The sensible and latent heat transfer between the space air and the surroundings can be classified as follows: 1. Space heat gain qe, in Btu/h (W), represents the rate at which heat enters a conditioned space from an external source or is released to the space from an internal source during a given time interval. 2. Space cooling load, often simply called the cooling load Qrc, Btu /h (W), is the rate at which heat must be removed from a conditioned space so as to maintain a constant temperature and acceptable relative humidity. The sensible cooling load is equal to the sum of the convective heat transfer from the surfaces of the building envelope, furnishings, occupants, appliances, and equipment. 4. Space heat extraction rate Qex, Btu /h (W), is the rate at which heat is actually removed from the conditioned space by the air system. The sensible heat extraction rate is equal to the sensible cooling load only when the space air temperature remains constant. 5. Coil load Qc, Btu /h (W), is the rate of heat transfer at the coil. The cooling coil load Qcc, Btu/h (W), is the rate at which heat is removed by the chilled water flowing through the coil or is absorbed by the refrigerant inside the coil. Cooling load usually can be classified into two categories: external and internal. External Cooling Loads[1] These loads are formed because of heat gains in the conditioned space from external sources through the building envelope or building shell and the partition walls. Sources of external loads include the following cooling loads: 1. Heat gain entering from the exterior walls and roofs 2. Solar heat gain transmitted through the fenestrations 3. Conductive heat gain coming through the fenestrations 4. Heat gain entering from the partition walls and interior doors 5. Infiltration of outdoor air into the conditioned space Internal Cooling Loads[1] These loads are formed by the release of sensible and latent heat from the heat sources inside the conditioned space. These sources contribute internal cooling loads: 1. People 2. Electric lights 3. Equipment and appliances For [1-1] [1] see the section of references CHAPTER 2 COOLING LOAD CALCULATION PROCEDURE [2]The estimation of cooling load for a space involves calculating a surface by surface conductive, convective, and radiative heat balance for each room surface and a convective heat balance for the room air. Based on the same underlying principles, the following methods have been developed for calculating the cooling load. Cooling Load by Transfer Function Method (TFM). Total Equivalent Temperature Difference (TETD) method. Cooling Load Temperature Difference (CLTD) method. Transfer Function Method (TFM)[1] The transfer function method or weighting factor method is a simplification of the laborious heat balance method. The wide application of the TFM is due to the user-friendliness of the inputs and outputs of the TFM software and the saving of computing time. In the transfer function method, interior surface temperatures and the space cooling load were first calculated by the exact heat balance method for many representative constructions. The transfer function coefficients (weighting factors) were then calculated which convert the heat gains to cooling loads. Sometimes, transfer function coefficients were also developed through test and experiments. Calculation Procedure The calculation of space cooling load using the transfer function method consists of two steps. First, heat gains or heat loss from exterior walls, roofs, and floors is calculated using response factors or conduction transfer function coefficients; and the solar and internal heat gains are calculated directly for the scheduled hour. Second, room transfer function coefficients or room weighting factors are used to convert the heat gains to cooling loads, or the heat losses to heating loads. As described in Sec. 6.2, the sensible infiltration heat gain is the instantaneous sensible cooling load. All latent heat gains are instantaneous latent cooling loads. The TFM is limited because the cooling loads thus calculated depend on the value of transfer function coefficients as well as the characteristics of the space and how they are varied from those used to generate the transfer function coefficients. In addition, TFM assumed that the total cooling load can be calculated by simply adding the individual components-the superposition principle. However, this assumption can cause some errors. Total Equivalent Temperature Difference (TETD) Method[1] In the total equivalent temperature difference (TETD)/time-averaging (TA) method, heat gains of a number of representative exterior wall and roof assemblies are calculated. The internal heat gains and conductive heat gain are calculated in the same manner as in the TFM. The radiant fraction of each of the sensible heat gains is then allocated to a period including the current and successive hours, a total of 1 to 3 h for light construction and 6 to 8 h for heavy construction. The TETD/ TA method is also a member of the TFM family and is developed primarily for manual calculation. TETD/TA is simpler in the conversion of heat gains to cooling loads. However, the time-averaging calculation procedure is subjective-it is more an art than a rigorous scientific method. Also the TETD/TA method inherits the limitations that a TFM possesses if the TFM is used to calculate the TETD. Cooling Load Temperature Difference (CLTD) Method [2] CLTD is the method we used to calculate the cooling load of the project we were assigned. The CLTD method accounts for the thermal response in the heat transfer through the wall or roof, as well as the response due to radiation of part of the energy from the interior surface of the wall to objects and surfaces within the space. The CLTD method makes use of (a) the temperature difference in the case of walls and the roofs and (b) the cooling load factors (CLF) in the case of solar heat gain through windows and internal heat sources, i.e , Q = U x A x CLTDC Where Q is the net room conduction heat gain through roof, wall or glass (W) A is the area of the roof , wall or glass (m2) U is the overall heat transfer co efficient (kW/m2.K) CLTDC is the cooling load temperature difference (oC) For [1] [2] see the section of references CHAPTER 3 CALCULATING COOLING LOADS USING CLTD Outdoor Design Conditions[2] ASHRAE Table A 2, F1980, provides the outdoor design conditions for various locations in many countries including India, Malaysia and Singapore. The summer design column lists hourly temperature which is exceeded by 1%, 2.5 % and 5% of all the hours in the year. Selection of Indoor Conditions[2] In private homes, the indoor conditions may be chosen by the owner. But in public premisis, various codes and regulations and ordinances dictate the limits of the specific indoor design conditions. For some critical occupancy, such as, hospitals, nursing homes, computer rooms, clean rooms, etc. specific indoor design conditions will usually be established by the regulating authorities or the owners. Transmission gains[2] Heat transfer through the different components of the building envelop occurs primarily the process of conduction and convection and is generally referred to as transmission load. Transmission heat transfer is given by the following equation: Q = = (U) (A) (TD) Where, Q is the heat transfer rate (W) Rt is the sum of the individual thermal resistances (m2.oC/W) A is the surface area perpendicular to heat flux (m2) TD is the design temperature difference between indoors and outdoors U = 1/Rt is the overall heat transfer co efficient (W/m2.oC) With, Rt = R1 + R2 + à ¼ + Rm for resistance in series. The values of thermal resistances are provided for specific thickness for typical building materials usually designated by U. For materials that vary in thickness according to the application, specific conductivity k is listed in terms of unit thickness. The relation between the two is R = Where k is the coefficient of thermal conductivity (W/m.K) L is the length of the conduction path (m). CLTD/CLF calculation[2] To account for the temperature and the solar variations, the concept of cooling load temperature difference (CLTD) is introduced. The CLTD is a steady state representation of the complex heat transfer involving actual temperature difference between indoors and outdoors, mass and solar radiation by the building materials, and the time of day. The following relation makes corrections in the CLTDs for walls and roofs for deviations in design and solar conditions are as follows: CLTDc = [(CLTD + LM)k + (25.5 Tr) + (To 29.4)] f Where CLTDc is the corrected value of CLTD. LM is the colour adjustment for light coloured roof. Tr is the design room temeperature To is average outdoor temperature, computed as the design temperature less half the daily range. f is attic fan factor Solar heat gain[2] When solar rays impinge on a glass surface, some of the radiation is reflected back outside before penetrating the glass. Of that radiation which is not reflected, some is transmitted through the glass and some is absorbed by the glass. The remaining radiation is refracted slightly and goes on to heat the contents of the room. If there is external shading, such as with blinds or drapes or shades, a portion of t radiation entering the room is confined to the area immediately adjacent to the window and has a diminished effect on the conditioning of the room. All of these effects are accounted for to some degree by the following relation for calculation of cooling loads due to solar radiation: QSHG = A(SC)(SHGF)(CLF) Where QSHG is the solar radiation cooling load (W) A is the open glass area (m2) SC is the shading co efficient for various types of glasses and shadings SHGF is the maximum solar heat gain factor for specific orientation of surface, latitude and month (W/m2) CLF is the cooling load factor, dimensionless. Internal Loads[2] Lighting is often is the major space cooling load component. The rate of heat gain at any instant, however, is not the same as the heat equivalent of power supplied instantaneously to these lights. Only part of the energy from lights is transferred to the room air by convection, and thus becomes the cooling load. The remaining portion is the radiant heat that affects the conditioned space only after having been absorbed by walls, floor, furniture, upholstery, etc. and released after a time lag. The cooling load imposed by these sources is given by Q appliances= P(CLF) Where Q appliances is the cooling load due to equipment of appliances (W) P is the input operating power rating of the appliance or equipment (W) CLF is the cooling load factor (dimensionless) depending on operating hours, room construction, and air circulation. Occupancy[2] The people who occupy the building give off thermal energy continuously, the rate of which depend on the level and type of activity in which they are engaged. For the sensible portion of the heat released, a cooling load factor similar the one applied to lights and appliances has been developed to account for the lag in time between occupancy and the observed cooling load. The sensible cooling load due to people is therefore, QS = (N)(GS)(CLFS) Where QS is the sensible cooling load due to occupants (W) N is the number of occupants GS is the sensible heat gain depending on activity and time for entry (W) CLFS is the cooling load factor (dimensionless) for people. The latent heat gain from occupants is found by Ql = (N)(Gl) Where Ql is the latent heat gain N is the number of occupants Gl is the latent heat gains from occupants depending on activity and time from entry Ventilation/Infiltration[2] Heat gain from ventilation and infiltration needs to be considered in the cooling load calculations. General Design Guidelines[2] The general procedure required to calculate the space cooling load is as follows: Building configuration an characteristics: Determine the building location, orientation and external shading, building materials, external surface colour and shape. These details are usually obtained from building plans and specifications. Outdoor design conditions: Obtain the outdoor weather data for the building location and select the outdoor design conditions. Indoor design conditions: Specify temperature, humidity, air velocity, etc. Operating schedules: obtain a schedule of lighting, occupancy, internal equipment, appliances and processes generating heat load. Date and time: Select the time of the day and month to estimate the cooling load. Several different times of the day and several different months need to be analyzed to determine the peak load time. The particular day and month are often dictated by peak solar conditions.

In which main contribution was from people present in the mosque (almost half the contribution) and heat conduction through walls and windows glass. The contribution from each mode is shown in fig 6.1. Fig 6.1 Contribution from each mode of heat transfer in cooling load Recommendations Use 6 ACs each of 2.5 Ton and one of 1.5 ton, we will need all the ACs switched ON during Jumma prayers only. On normal days we will switch ON 3 or 4 ACs depending on the number of occupants. As the number of occupants decreases the required cooling load also decreases. For different values of occupants required cooling load has been calculated and shown in the fig 6.2. Fig 6.2 Relation between number of occupants and cooling load Normally 30 people are present in the mosque at prayer times so we need only 9.2 tons of refrigeration. We will switch ON three ACs of 2.5 tons and one of 1.5 tons We can minimize the Cooling load by Increasing the glass thickness By using opaque sheets on the outer side of the windows and doors By using reflecting and insulating material on the roof, reflective material will reduce solar radiation and insulating material will minimize conduction Growing trees on southern side

Charitable Works of Muhammad Ali :: Biography
Muhammad Ali is important in many ways. First, his boxing career success inspired many people to follow their dreams to attain greatness. Second, Muhammad Ali and Peter Arnell founded G.O.A.T. (Greatest of All Time) (Our). G.O.A.T. is a food and beverage company that seeks to inspire young adults to eat smarter, to live healthier lives, and to rise above their current status. G.O.A.T. products are expected to come out early next year. Third, Muhammad Ali has raised over fifty million dollars for charities throughout the world. Finally, although Ali retired from the sport in 1981, he showed his love for it by inspiring the Muhammad Ali Boxing Reform Act. This act promotes fairness in boxing. I have learned many new things about Muhammad Ali. Previously, I thought he was the greatest boxer of all time, however after my researching, I think he is one of the greatest persons of all time. I never would have guessed that by the time he was 19 years old he had already won six Kentucky Golden Gloves, two National Golden Gloves, two National AAU Titles, and an Olympic gold medal (Howard). I never knew that Ali refused to join the army because of his religion. Because of this, his boxing license was cancelled. He was stripped of his title, and was sentenced to five years in prison for draft evasion. The Supreme Court, however, reversed the draft evasion conviction on June 29, 1971, and Ali continued his boxing career. I did not know that Muhammad Ali was honored as a United Nations messenger of peace and went to Iraq in 1990 to negotiate and successfully get fifteen United States hostages released.
