World War I And II - 1057 Words

Two of the most agonizing periods in the 20th century, World War I and II, left a lasting impact on society economically, politically, and socially. As we have read in detailed archives on both world catastrophes, the nature in which violence shaped society after the war varied greatly. Ernst Jà ¼nger in Storm of Steel shares his heroic memoirs from fighting on the German front in World War I. Art Spiegelman tells the very personal and emotional story of his father, a survivor of World War II’s Holocaust. Throughout the war, Ernst reminds us of his heroism and his withstanding sacrifice, up until he is badly injured and no longer able to fight. Ernst is proud of his achievements in the war, and shares his book with the world so that we can admire his heroism. Where as Art Spiegelman’s parent’s, lived on after the Holocaust depressed—Art’s mother committed suicide 23 years after the war! After reading these two accounts, the biggest difference bet ween World War I and World War II, was how society reacted to the violence and harsh conditions enforced upon them. Civilians after World War I persevered their struggles to counteract the destruction that impeded their nation’s growth. On the other hand, Civilians of World War II were left in a state turmoil. With the formation of alliances fifty years prior to the start of the war, the enhancement of arsenal, and the preparation of combat tactics, World War I was a proverbial ticking-time bomb ready to detonate.

The Energy Stored On Various Foods Using A Homemade...

The Energy Stored In Various Foods Using a Homemade Calorimeter Naomi Hernandez Little Rock Central High The Energy Stored in Various Foods Using a Homemade Calorimeter The purpose of this experiment is to investigate how the caloric energy in food varies in different foods and the correlation between high fat foods and calories using a homemade calorimeter. The hypothesis is that if foods with higher fat content have more energy than nonfat food, then fatty foods with more caloric energy will have higher measurements on the calorimeter, because fatty foods have calories than other foods. As the content of fat in food rises the energy stored in that food will be greater than nonfat foods. â€Å"A calorie is a unit of energy† though it does†¦show more content†¦With an excess of calories, an individual could become overweight or obese, because the calories not used for used for basic functions are converted into fat for later usage. If the individual does not participate in physical activity, the remaining fat will not be burned off, leading to ex cess of fat (Abdallah, et al. n.d.). Too many empty calories, or calories with no nutritional value, increase the chances of obesity and other weight related issues. These calories derive form added sugar and solid fats (Weight Management, .n.d.) Solid fats refer to fats that are solid at room temperature such as: â€Å"butter, milk fat, beef fat (tallow, suet), chicken fat, cream, pork fat (lard), stick margarine, shortening, hydrogenated oils, coconut oil, palm and palm kernel oils†. Although some are named oils, it is because they derive from plants, they are considered solid fats because of the high concentration in saturated and fatty acids(Calories. n.d.). â€Å"Fats are concentrated sources of calories†, and foods with added sugars or eaten in large portions can account to an excess in calories and lead to weight gain (How Do I, .n.d.). So foods with greater empty calories that tend to have solid fats lead excess in fat. For the purpose or this experiment food s that either are or have

Bacteriophage and depolymerase Free Essays

Introduction Bacteriophage which is also known as bacteria eater refers to viruses that infect bacteria.Bacteriophages are known to only replicate within host cells and must attach to a specific receptor on the surface of a bacteria cell to initiate infection. The contact between the phage and the receptor is very definite which means that a phage type will only bind to a particular receptor molecule thus all bacteriophage are not alike. We will write a custom essay sample on Bacteriophage and depolymerase or any similar topic only for you Order Now Depolymerase refers to an enzyme that catalyses the breakdown of macromolecules to simpler molecules. Pseudomonas aeruginosa is commonly described as an opportunistic pathogen that causes morbidity and mortality in humans, animals and plants. Due to its exceptionally high metabolic versatility in utilizing numerous organic compounds and its adaptability to various conditions, it can be commonly found in terrestrial soil, fresh water environments and can grow in a variety of low-nutrient conditions. Bacteria and depolymerase are linked together due to the fact that the depolymerase helps the bacteria by breaking down large molecules and making it easier for the bacteria to attach to the host. Figure 1-Diagram of a bacteriophage Background information-basic information on Bacteriophages Bacteriophage are host specific viruses that targets only certain types of bacteria. They are made up of outer protein caspid enclosing a genetic material which could be SSRNA,dsRNA,ssDNA or dsNA.Bacteriophages are very common in places like soil, sewage or reservoirs infected by bacteria hosts. It’s been suggested that bacteriophage might be an effective way to treat bacterial infections but studies showed that they are quickly removed from the body and hence show little clinical value therefore mostly used in the laboratory. Biofilms are made up of bacteria and other microbial cells attached directly to a solid phosphate or indirectly through associated expolysaccharides and other polymetric material. The nature of a biofilm depends on the nature of the attached microorganisms and of polymers which they secrete. The physiological conditions also greatly affect biofilm thickness and physical properties. Large numbers of phages are found in many environments as biofilms. The evidence of the ability of bacteriophage –borne polysaccharide depolymerase enzymes to degrade bacterial polysaccharides have been proved (Adams Park 1956),Phage polysaccharide depolymerase are commonly seen in electron micrographs as spikes attached to the phage baseplate.In a liquid culture,degredation of bacterial capsular material by phage-borne polysaccharide depolymerise occurs in a defined sequence. The phage depolymerise binds to the capsular material which is the secondary receptor and degrades the polymer until it reaches the cell surface where it binds to an outer membrane receptor which is the primary receptor and infects the bacterium.Therefore,bacterial lysis will occur.This however results to a clear area in the lawn of growing cells host cells. The clearing that occurs is called a plaque and each plaque is believed to have originated from the replication events that began with one bacteriophage (virion).When the number of plaque forming units is counted, t he number of virus infectious units present in the original sample can be calculated. This procedure also permits the isolation of pure virus stains. If a plaque originated from a single virion, then all the virons in that plaque should be genetically identical. Some of the virus from the plaque can be picked and inoculated into a fresh bacterial culture inorder to establish a pure virus line (Madigan et al 2007) The purpose of this review is to isolate a bacteriophage capable of infecting a specific host bacterium. The improvement of an environmental sample ie water, for the presence of bacteriophages infecting a particular host can be carried out by inoculating water sample with the host organism and waiting for lysis to occur.Isolating of bacteriophage allows the determination of bacteriophage particles which are capable of initiating productive infections of their host bacterium in the original sample. The use of the selective enrichment in this review is to increase the probability that colonies of the desired organism would be formed. Any type of bacteria strain can be infected by bacteriophage like ecoli, pseudomonas, and salmonella. This study is based on the isolation of a bacteria strain of pseudomonas aeruginosa, not all pseudomonas strains are similar but Variability exists in the growth, curves and antibiotic resistance of different pseudomonas aeruginosa isolates. Different hypothesis have shown that isolates of p.aeruginosa could also possess some differences in their surface molecules and as a result differences in the phage receptors present on their surfaces. Mechanisms by which bacteria Infects host cells are:Adsorption,Sheath Contraction and Nucleic Acid Injection. Different methods are used for the isolation of bacteriophage from water according to different articles. Khan, N. H., Shii, Y., Kimata-Kino, N., Esaki, H., Nishino, T., Nishimura, M., Kogure, K. (2007). stated that bacteria can be isolated by different ways which include: Water sampling- In this process, selective and non selective agar culture were used for to isolate and identify P.aerruginosa and appropriate volumes of water samples are filtered using sterilized plates and Nutrient Broth agar. Identification by BD phoenix system-The phoenix system uses one identification (ID) and AST (antimicrobial susceptibility) combination panel with the ID substrates on one side and the microbial drugs on the other. Serotyping- Sereotyping for O-group specific abntigen was carried out by using P.aeruginosa kit and all isolates were tested for O-goup specific antigens. Purified Gel Electrophoresis-This was used to clarify genetic relatedness among the strains.

European Self Reflection

Question: Discuss about the European Self Reflection. Answer: It is important to engage self-reflection on one's experience over a given subject (Bruun, Lammers, Srensen, 2013). We are exposed to various issues in our communities, families, and workplaces. This personal reflection explains my experience on issues facing community development and issues that arise while working as a team in a project. Teamwork promotes creative and critical thinking skills for the members (Littlejohn, Milligan, Margaryan, 2012). I learned that the achievement of project goals by a team has pitfalls since some members are free riders. I noted that when some members of a group are free riders, the project goals and activities get sabotaged. However, with effective collaboration, the team produced reasonable results. What made me happy is how the project manager assigned duties to every member to control free riding. Some team members did not want to share their ideas, never assisted the group to solve conflicts, never listened to colleagues ideas, and let their partners do all their works. I learned that, when some members of the panel get lazy, the project goals cannot get realized. Also, I noted that it is important to share my ideas with the partners so as to make sound decisions about the project success. I was happy of how the project manager emphasized on team work. Personally, I have been working with different teams who come from various communities. In all groups, we have made numerous improvements on how we handle tasks. We have improved our technology by creating a server set up over which ideas about our projects are shared. Unlike the past, we can communicate on one platform and invite different perspectives on how to achieve project results. I learned that the success of a project is both personal and a collective act. Individual team members innovate ideas and share them collectively with the entire group. I observed that once individual ideas get respect from the team, then a collective thought is encouraged. I noted that collective knowledge is supported by virtual interactions amongst the group. In my field work internship, I learned that people from different communities have different social beliefs and norms of life. My project manager informed me that while interviewing community members from various areas on their perceptions of drug abuse, I should approach the people differently (Littlejohn, Milligan, Margaryan, 2012). I noted that the various communities have different opinions on substance abuse due to their cultural beliefs. In respect to drug usage by communities, I have seen the local leaders doing something good to address this matter. From their feedback, I realized that the local government authorities have been organizing anti-drug consumption road shows in the community to educate people on the adverse effects of its use. However, I see for myself people carelessly drinking in bars. I am glad that everyone who we interviewed in the field work gave maximum cooperation and did not frustrate us. I am so proud to be one of the reasons behind this success, and I am assured that every team member was happy about how the entire project was a success. I enjoyed working with the team and the community. References Bruun, L., Lammers, K., Srensen, G. (Eds.).
