Cold Winter Essays - Startup Cult, David Meece,

Cold Winter It was in the middle of winter on a dark smoggy night, chills were running through the house in and out of my room like a quiet ghost silently coming and silently going. As I lie awake in my bed thinking of what the next day should bring, my eye's start to grow heavy as I doze off. In the distance I hear a faint booming sound, soon it starts getting louder and louder and still louder until I could hear nothing but the noise. I was unpleasantly startled and hurried over to my window. As I look out I could see nothing but smoke and fire, catching this by surprised I ran to my little brother's room, finding no one. Then in the distance I could hear faint voices of terror calling my name. It sounded as if it was coming from out side, so I ran as fast as my Nike slippers could carry me down the stairs and outside into my front yard. I find the rest of my family there, along with my neighbors and their son, my best friend. I just stood there in horror with the rest of my family and friends. We had no idea what had happened. The next morning I really don't remember very clearly, but what I do remember was reading the news paper and coming across an article about a house burning down not to far from mine. I really didn't know what exactly to think at that time until it all clicked upstairs. The noise the night before had been the house burning down and the natural gas line exploding. Later in the article it said that our block of houses wouldn't have any natural gas heating until the line was repaired. The first thing I did was run to the kitchen, finding my Mother and Father there fixing breakfast. I started talking so fast I really don't even know what came out. My Mom told me to calm down and sit at the table. Doing so she gave me a glass of milk, and seeing that I was distressed sat down next to me and asked me what was on my mind. Taking full advantage of her attention I told her as slowly and detailed as possible at the time being. As soon as I had finished my frantic attempt to get all that out, she didn't laugh at me but just got that look in her eyes where you know that she didn't believe a word of it. The fist thing she said in response was "Where did you hear about this?" I answered her as fast as possible "In the news paper". Stunned at my at my quick answer she told me to bring her the article. So I ran back up the stairs and snatched the paper from my bed. When I got down stairs I laid the article out flat in front of my mom's face. A subtle but shocked look arose on my mother's face, as she sank deeper into her chair. Shutting off the radio, I sat down next to my dad asking him what we were going to do for heat, he just answered "I don't know I just don't know." shaking his head in resistance. Later that day I was over at a friend's house who had heat. We were playing a video game and eating chips in his living room. The walls had many game heads on them, one of the nicer ones was a whole stuffed mountain lion that his dad once had a special tag to hunt. The whole time I was there I was brainstorming on how to get heat in our house. Soon I was in the back seat of our extended cab black GMC pickup. My little brother was on my mom's lap and my dad was just starting to drive onto the onramp. Which is not an easy task on a daily basis, when you live in Detroit. As soon as we started getting close to the freeway there was a huge traffic jam. I think we must have been there for about and hour and a half. I don't really remember because I was trying to go to sleep. When I woke up we were on the freeway driving about 40 m.p.h. because there were so many cars. But soon we were back in my neighborhood. We stopped at the local McDonald's to get some lunch. Luckily my dad

The effect of ultraviolet rays on the growth of P. fluoresce essays

The effect of ultraviolet rays on the growth of P. fluoresce essays Rapidly growing bacteria are exposed to constantly changing environments and must be able to adapt quickly if they are to survive and successfully compete with other organisms. Unless they take advantage of the change and respond quickly they will be crowded out by other organisms (Nester, 2004). There are many factors in the environment that are subject to change, for example availability of nutrients, water, oxygen, temperature and even effects of ultraviolet (UV) light. The modeling of the response of living organisms to a change in environment is an important issue of current interest. An example is the effect of ultraviolet radiation on biological systems (Delprato, 2001). UV rays are short waves of invisible light. A bacterium has three different mechanisms to adapt to their changing environment. One involves genetic modification or mutation. When an organism is exposed to UV radiation, covalent bonds between thymine molecules of the same DNA strand are formed called thymine dimers. The covalent bonding between these two molecules distort the DNA strand, damaging it in such a way that the DNA can neither be replicated nor transcribed at the site of mutation. Bacteria as well as other organisms are able to overcome this type of damage and repair themselves. An enzyme, in the presence of visible light, is used to break the covalent bonds. This process is called photoreactivation. Photoreactivation restores the bacterial DNA to its original state, thus allowing for replication and transcription. This process is thought to be important component of the bacterial arsenal in the repair or reversal of UV mediated DNA damage (Kim, 2001). Another mechanism to repair UV damage is called dark repair. It is called dark repair because it takes place in the absence of light. Dark repair involves another enzyme that excises the damaged segment from a strand of DNA and yet another enzyme repairs the resulting break by synth...

Critical questions - Coursework Example An example of when I used critical thinking is when my laptop was stolen at my place. My best friend Max and his distant cousin Gabriel had come over to play video games. After sometime, I noticed my laptop was missing and confirmed this after looking for it all over the house. Max insisted that only Gabriel could have taken it since he was the only person among us who had gone outside. Max insisted we beat him up until he produced the laptop, but after thinking very carefully, I realized that beating him up would do more harm than good so I decided to leave the issue with the police to solve it. I reported the matter to the police, and Gabriel owned up and I got my laptop back. Critical thinking is not only important in the professional discipline, but it is also important in the basic life. For example, I decided not to agree with max after carefully examining the implications of our action. If we would have beaten him up, we would have been charged with taking the law into our own hands and assault among other things. Therefore, it is important to use critical thinking in order for us to reach sound
