Little Ice Age - 2007 Words

Europe had experienced a general cooling of the climate between years 1150 and 1460 and a very cold climate between 1560 and 1850. This event came to be known as the â€Å"Little Ice Age.† This cold weather had impact on agriculture, health, economics, emigration, and art and literature . The term â€Å"Little Ice Age† was named by Francois Matthes in 1939 to describe the most destructive climate drop in Europe. This ice age was consisted of mountain glaciers which brought temperatures as low as 2 degrees Fahrenheit. Numerous people got sick and some were even killed and starved to death because of a famine. Farms and villages were lost due to the cold weather. It is unknown on what caused this â€Å"Little Ice Age.† We do know that this event impacted†¦show more content†¦This ice age not only affected humans, but also the wildlife and everything around it. The plants enzymes are failing them and their roots are struggling to find a way through the fr ozen soil. These plants can’t grow and maintain themselves in these conditions. Pollination is nearly impossible during this time. The plants aren’t able to give off much oxygen into the atmosphere, which we breathe in. The true impact of â€Å"The Little Ice Age† began around 1600 and lasted until the 1800’s. During that time in Europe is when it was at its height. It was considered to be the most significant climate event of the last millennium. Only until recently have climatologist discovered research of climate conditions in historical times. As stated before, no one is quite sure how â€Å"The Little Ice Age† evolved. Climatologist and historians have had many discussions on what they think was the main cause of the ice age. Today they are able to determine the yearly average temperatures, rainfalls, volcanic activity, and the effect of the sun during that period . What we know is that the sun experienced a â€Å"quiet† period, meaning its intensity was not that strong. Therefore, a cooling occurred. Sunspots which determine the suns strength were noted to be in decline. Volcanic activity is to be another known source of the cause. As the volcanoes erupted they shot out particles and gases into the air. With these gases floating in theShow MoreRelatedThe Little Ice Age and Climate Change Today Essay1296 Words   |  6 PagesThe Little Ice Age and Climate Change Today Roland Ward ES117-2A-77: Natural Disasters 8 December 2012 Keith Earnshaw Abstract The little ice age gave us a glimpse as to how climate change can affect our society.

Analysis Of The Play Fences By August Wilson - 940 Words

The play Fences by August Wilson, explains and explores the lives of the Maxson family, an African American family in 1957. Like in most plays each of the main characters has a strong desire that they want to achieve throughout the course of the story. Rose Maxson, the matriarch of the family, wants to be with people and connected to them. She does not want to be alone. This is seen through her family’s history, her feelings on marriage, and the family she has made for herself. Rose wants to create the opposite of the family she had growing up. After Troy tells her that he has gotten another woman pregnant she berates him for not only cheating, but also creating a family of halves. Rose is against this, â€Å"And you know I ain t never wanted no half nothing in my family. Everybody got different fathers and mothers†¦Can t hardly tell who s who. Can t never sit down and talk about Papa and Mama† (pg 75). Rose felt alone in her family of halves and disconnected from her siblings because they all had different parents. She missed out on the strong sibling relationships that form because there were too many different adult figures in her life and her sibling probably did not all live in the same place. There is also no mention that she keeps in contact with any of her family members now, so the family that she makes now is all that she has to keep her company.

Seismic Force Modification Factor

Question: Discuss about theSeismic Force Modification Factor. Answer: Literature Review: From the research (Samantha, 2010)it can be found that the design of a structure can be made cost efficient and at the same time the safety performance of the structure can also be maintained. The elastic behaviour of a structure is expected. It causes a reduction in the design and this seismic force gets influenced by the application of a factor which is known as Seismic force modification factor. It is denoted as R. it helps to simply the designing process of the structure. With the application of R, only linear elastic static analysis is required in a structure. The behaviour of the reinforced steel is capable of controlling the responses of the structural elements of a reinforced concrete that are subjected to the earth quake loading. Therefore, it is very much important to develop an analytical model so that this problem can be avoided. The model must be capable of predicting the primary characteristics of steel. It must be measured within the specified range. The past records or the history of loads must be analysed in order to predict the characteristics and the impacts. If design base shear is denoted by Vt and design seismic force is denoted by Vs, then Seismic force modification factor ( R ) can be obtained with the help of the following equation: Vs = Vt / R Or, R = Vt / Vs According to the research (Adeel, 2009), R factors are known to be very important seismic design tools that can be used in order determine the degree of inelasticity that can be expected in a structure at the time of an earth quake. R factor has the capability to reflect the structure for dissipating energy using the inelastic characteristic of the structure. From the research it has also been known that it is also used for reducing the design forces of a structure. The seismic codes depend on the ductility and reserve strength and suitable seismic code helps to improve the ability of a structure to dissipate and absorb energy (Denis et al., 2003). Seismic force modification factor is also known as response reduction modification factor and according to the research, the value of R can be obtained with the help of the ductility reduction factor and the over strength factor (Adeel, 2009). The over strength factor is denoted as ? whereas the ductility reduction factor is known as R. The R factor can be obtained with the help of the following equation: R = R x ? The values of the seismic force that are used in the design of a structure are generally computed with the help of the diving forces which are associated with the elastic response of the R factor. The R factor is required in order to develop the lateral strength of a structure and also to sustain inelastic deformations i.e. the ductile behaviour of the structure (Adeel, 2009). Therefore the value of the R factor is very important in order to determine the design specifications of the design of the seismic loading. The response modification factor can be obtained with the help of the following expression also (Adeel, 2009): V = 2.5 x ( pga ) x ( W / R ) Or , R = ( 2.5 x ( pga ) x W ) / V Here, V denotes the design base shear. The weight of the structure is denoted by W whereas pga represents the peak ground acceleration. According to the research (Ferraioli et al., 2012) force reduction factor ( q factor ) is the another name of the response modification factor ( R factor ). There are different expressions that can be used in order to calculate R factor. From the research (Ferraioli et al., 2012), it has been found that the R factor can be calculated with the help of the following equation also: R = RS x R x R Here, Rs denotes the strength reduction factor, R represents the ductility reduction factor and R denotes the damping reduction factor (Ferraioli et al., 2012). From the research it has been known that the over strength reduction factor that is recommended by EC8 for a multi story structure is conservative. From the research paper (Ferraioli et al., 2012) it can be found that the beam column joint is very important zone in case of a frame that is capable of resisting reinforced concrete moment. From the research (Adeel, 2009) it has also been found that a structure is influenced from different types of ground shaking. The nature of the shear failure is brittle. The capability of the structural system for resisting the actions allows the design to prevent the seismic forces and also to helps to provide a elastic response. The reduction can be done with the help of the q factor. References Adeel, Z. (2009). Response Modification Factor Of Reinforced Concrete Moment Resisting Frames In Developing Countries.
