Hazard from Space

Mass extinction theory attributes the extinction of living organism to collision of extraterrestrial objects such as asteroids with the Earth. The collision results into drastic climatic change due to suspended clouds of dusts that affects radiation from the sun. Drastic and intermittent occurrence of meteors and asteroid resulted to a gradual loss of living organisms during the course of the Earth’s history.Advertising We will write a custom assessment sample on Hazard from Space specifically for you for only $16.05 $11/page Learn More The most credible example giving plausible explanation regarding mass extinction is the dinosaur extinction, which occurred approximately 65 million years ago. Rogers claims that, â€Å"†¦basic experiments have been done, and it seems clear that the iridium came from an extraterrestrial source within the solar system† (25). However, debate concerning dinosaur extinction still rages. The massive impact o f extraterrestrial objects did not cause mass extinction of dinosaurs. The extinction of dinosaur may not have occurred due to drastic impact of meteors and asteroids since the probability of extraterrestrial objects to occur in future is quite negligible. â€Å"Astronomers theorized that the Oort cloud of comets could cross the path of our solar system every 26 million years, and would possibly rain comets on our planet for a few million years† (Waldner 19). This prediction has not happened and it seems it will never happen. Dinosaur basis of mass extinction theory do not give plausible explanation for extraterrestrial bodies since they occurred only once during the period of dinosaurs and there is no possibility of future occurrence. If there was subsequent occurrence of extraterrestrial bodies and concomitant loss of living organism, then this theory would be valid, but since the occurrence is indefinite, extraterrestrial bodies did not cause extinction of dinosaurs. Selec tive extinction is another line of evidence that disapproves the dominant theory of dinosaur extinction. If the great impact of extraterrestrial bodies’ collision with Earth resulted into drastic climatic change, then under what mechanism did selective extinction occur? There is no credible explanation of the mechanisms surrounding extinction and survival of organisms. The theory concentrates on extinction without giving plausible explanation of the survival mechanism of the other organisms. Moreover, extinction studies focus on dinosaur extinction alone and extrapolated findings, and may be, other organism did not undergo mass extinction as claimed. Joblonski argues that, â€Å"lack of understanding of the physiology of dinosaurs makes the issue more complex; if they were endothermic, why did they not survive like birds and mammals? If they were ectothermic, why did small dinosaurs not survive like small reptiles? (205). Hence, the mechanism of survival or extinction remain s insufficient in explaining the nature of mass extinction.Advertising Looking for assessment on astronomy? Let's see if we can help you!

Iridium originates from the solar system and their sedimentation on the rock surfaces signifies the occurrence of the extraterrestrial bodies. However, â€Å"a new study has challenged the theory by claiming that those supposed clues are nothing more than fossilized balls of fungus, charcoal, and fecal pellets† (Rogers 34). The evidence shows that even organic matter that occur naturally on Earth when subjected to cycles of fire can produce iridium, which is a fossil complex. Therefore, fossils records have proved that fungal sediments are ubiquitous and their presence over a long period of history under intermittent fire out brakes transform ed them into cretaceous fossils. Therefore, based on the evidence gathered in this research paper, the extinction of dinosaurs did not result from a massive impact event.

Digital forensic analyst Case Study Example | Topics and Well Written Essays - 1250 words

Digital forensic analyst - Case Study Example The paper also outlines how the cases have had an impact on the trajectory of digital computer forensic and the work of digital forensic analyst. Case 1: U.S. v. Diaz The case between U.S and Diaz involved marijuana in New Mexico. In this case, Jesus Manuel Diaz had more than 1000 kilograms of Marijuana he wanted to distribute in the United States using his trucking company, JD Easyline (Admin, 2011). In December, 11th 2009, the United States district court heard that Daiz drove his truck eastbound from Mexico to the Arizona border where he intended to distribute Marijuana hidden in his truck. Being the Diaz wanted to cross the border with the marijuana onboard his truck, he had falsified the paper work detailing the real weight of the truck and the merchandise onboard. After arriving at a border booth, he went ahead to get the paperwork necessary for him to cross the border with the truck, but the credential booth was closed on that day. As a result, Diaz went out of his truck and met Officer Smid, whom he presented all the paper work including his driving license in pursuit of a clearance letter. However, Smid was worried about the weight Diaz had quoted in his paper work. The gross weight of Diaz’s truck was way below what Smid expected. Smid argued that an empty truck with fuel weighed close to 33,000 pounds. However, Diaz had pointed that the merchandise onboard was 9,762 pound, which concerned Smid because some weight was uncounted in the truck. Smid inspected Diaz paperwork and questioned the discrepancy in weight, which Diaz attempted to explain. He argued that some shippers often put more weight on the truck than necessary. An inspection of the truck revealed that Diaz did not have a CB radio and he had four cellphones. Furthermore, Smid discovered the Diaz was uneasy and was scratching his head, a behavior he had not displayed at the start of the conversation. The seal of the truck was a commercial seal and Smid noted that there was some air freshener in the truck, though this was missing in the bill of lading. A through search of the truck using a sniffer dog revealed more the 3,300 pounds of marijuana (Admin, 2011). In addition, a laptop computer and printer, Diaz used to falsify and print the bill of lading was found. A computer forensic testified in the court that Diaz had deleted a program he used to create a false bill of lading to justify the additional weight of marijuana. Forensic analysis revealed that the bil l of lading was not the one the dollar store issued to Diaz. This evidence in this case had a significant impact on the case because it Diaz was found guilty and convicted. While Diaz had succeeded to alter the bill of lading, the work of computer forensic allowed the prosecutor to prove that Diaz had deleted software he used to make and print a false bill of lading. The case underscores the role of digital forensic analysts in discovering deleted files and linking the same to cases pending before courts of law. Moreover, the case proved that digital forensic analyst could determine the authenticity of documents by finding programs used to create them. In such cases, it would be easy for investigators to gather evidence

THE WEATHERMEN - Essay Example d against government officials targeted government buildings where warnings of evacuation were given to all officials with a warning that the attacks would be a form of protest against the government (Kirkpatrick, 2009). The rage demonstrations of 6th October, 1969 gave way to the bombing of the statue in Chicago that commemorated police casualties of the 1886 Haymarket riot. On 6th October, 1970 saw the statue rebuilt, however, it was blown up again by weathermen. It was rebuilt again and destroyed a third time by the same group. On February 16, 1970, the group planted a nail bomb on window ledge at the Park police station, San Francisco. One police officer was killed and a second officer was partially blinded. There were arson attacks in new York city were also blamed on the group with the explosion of Molotov cocktails filled with gasoline at the home of the Justice John Murtagh of the New York Supreme court being of the significant cases. Though no one was harmed in the explosion, it sent a very clear message since the judge was presiding over the case against members of the Black Panther party. The bombing of the New York Police headquarters in 1970 also falls into their mandate (Kirkpatrick, 2 009). Their strategic goal was to have the government cave in to their demands and stop bombing the Vietnamese. They wanted the government to provide democracy to all citizens in the world, and having to bomb one of the states would negate this principal (Kirkpatrick, 2009). They were only successful in instilling fear amongst the citizens because the government went on its campaign. They were arrested and by 1976, their numbers were decreasing and the divisions amongst them did not allow them to achieve much. The blacks and Hispanics were against their marginalization in the group and wanted to have a bigger voice in the way things were carried out in the faction (Kirkpatrick, 2009). Pape notes, â€Å"The cohesiveness of most groups is built mainly on having a common

Orr-sommerfeld Stability Analysis of Two-fluid Couette Flow

Orr-sommerfeld Stability Analysis of Two-fluid Couette Flow ORR-SOMMERFELD STABILITY ANALYSIS OF TWO-FLUID COUETTE FLOW WITH SURFACTANT V.P.T.N.C.Srikanth BOJJA1* , Maria FERNANDINO1, Roar SKARTLIEN2 ABSTRACT In the present work, the surfactant induced instability of a sheared two fluid system is examined. The linear stability analysis of two-fluid couette system with an amphiphilic surfactant is carried out by developing Orr-Sommerfeld type stability equations along with surfactant transport equation and the system of ordinary differential equations are solved by Chebyshev Collocation method[1,2]. Linear stability analysis reveals that the surfactant either induces Marangoni instability or significantly reduces the rate at which small perturbations decay. Keywords:Linear stability, Orr-Sommerfeld, Marangoni mode, Amphiphilic surfactant. NOMENCLATURE A complete list of symbols used, with dimensions, is given. Greek Symbols Growth rate Surfactant concentration Mass density, [kg/m3]. Dynamic viscosity, [kg/m.s].

Sub/superscripts Index i. Index j. Perturbed quantities Base state quantities INTRODUCTION Two layer channel flows and flows with and without surfactants have been given considerable importance because of its numerous industrial applications. Oil recovery[3], lubricated pipelining[4], liquid coating processes[5] are typical industrial situations where Two layer channel flows are often seen. Surfactants also have wide range of industrial applications for example in enhanced oil recovery[6]. Using Perturbation analysis, the primary instability of the two-layer plane Couette–Poiseuille flow was studied by Yih[7] and his studies revealed that even at small Reynolds numbers, the interface is susceptible to long-wave instability associated with viscosity stratification. Yiantsios Higgins[8] later extended this study for small to large values of wavenumber and confirmed the existence of the shear mode instability. Boomkamp Miesen[9] came up with the method of an energy budget for studying instabilities in parallel two-layer flows, where energy is supplied from the primary flow to the perturbed flow and instability appears at sufficiently long wave numbers through the increase of kinetic energy of an infinitesimal disturbance with time. In the presence of surfactant at the sheared interface, Frenkel Halpern[10,11] discovered that even in the stokes flow limit, the interface is unstable as the surfactant induces Marangoni instability, which was later confirmed by Blyt h Pozrikidis[12]. In the case of Stokes flow, they identified two normal modes, the Yih mode due to viscosity stratification inducing a jump in the interfacial shear, and the Marangoni mode associated with the presence of the surfactant. In contrast, at finite Reynolds numbers, infinite number of normal modes are possible and by parameter continuation with respect to the Reynolds number the most dangerous Yih and Marangoni modes can be identified. In this article, the effect of an insoluble surfactant on the stability of two-layer couette channel flow is studied in detail for low to moderate values of the Reynolds number. To isolate the Marangoni effect, gravity was suppressed in this problem and this was done by considering equal density fluids. Linear stability analysis was carried out by formulating Orr–Sommerfeld boundary value problem, which was solved numerically using Chebyshev collocation method[1][2] for all wavenumbers. Both Marangoni mode and Shear mode are detected and utmost focus is given to Marangoni mode as Shear mode is always stable at moderate to long wavenumbers under the influence of inertia. The rest of the paper is organized as follows. In  § Model description, the governing equations for the system in question are laid out, Normal mode analysis of the physical system is carried out, Orr–Sommerfeld boundary value problem is formulated. General description of Chebyshev collocation method and detailed description of numerical simulation of Orr–Sommerfeld boundary value problem by Chebyshev collocation method and validation of numerical method with literature data is given in  § Numerical method. Detailed discussion of results done in  § Results. The concluding remarks and outlook for further-work in  § Conclusions. Finally acknowledgements in and  §Acknowledgemnts. Model description Consider two super-imposed immiscible liquid layers between two infinite parallel plates located at, as in Fig. 1. Let the basic flow be driven only by steady motion of plates. It is well known that the basic ‘‘Couette’’ velocity profiles are steady and vary only in the span-wise direction and in the basic state, the unperturbed interface between the liquids is flat and is located at. The gravity is suppressed in this problem by considering equal densities in order to investigate the effects of surfactant and inertia on the stability of the system under consideration. The subscripts 1 and 2 refer to the lower or upper fluid, respectively and channel walls move in the horizontal direction, x, with velocities and. The interface is occupied by an insoluble surfactant with surface concentration which is only convected and diffused over the interface, but not into the bulk of the fluids thus locally changing the surface tension . Governing equations The mass and momentum conservation equations governing the two-layer system are , (1) Where subscript represents lower and upper liquid layers respectively. Here , Figure 1: Schematic sketch of Couette-Poiseuille flow with surfactant laden interface. The perturbed interface is shown as sinusoidal curve. is the concentration of insoluble surfactant. The associated boundary conditions for the system are no slip and no penetration boundary conditions at the walls. ,at and ,at The associated interface conditions are continuity of velocity, tangential stress and normal stress. Continuity of velocity at the interface , at The tangential and normal stress conditions at the interface are given by (2) Where are stress tensors, is unit normal, is unit tangent and Kinematic interfacial condition is The surfactant transport equation[13] at the interface is given by (3) Where is surface molecular diffusivity of surfactant. is usually negligible and neglected in this case. We introduce dimension less variables as follows , , , , The dimensionless variables in base state for the couette flow with flat interface and uniform surfactant concentration are given by , ( ) and , () Where is shear of basic velocity at interface and is given by We consider the perturbed state with small deviation from the base state: ,,,, Now we represent disturbance velocity in disturbance stream-functions and such that ,,, Performing normal mode analysis by substituting Where is wave number of the disturbance, and are constants, and is the complex wave speed. Linearizing the kinematic boundary condition yields . Linerarizing the dimensionless x and y-components of Navier-Stokes equation (2) followed by subtraction from the corresponding base state equations and elimination of pressure terms, yields two 4th order Orr-Sommerfield ODEs in stream-functions, one for each fluid.

By substituting the value of from linearized surfactant transport equation in linearized tangential stress balance condition gives (5e) For each value of Eqs. (4),(5) forms a eigen value problem, which was numerically solved using chebyshev collocation method[1,2] and QZ algorithm for determining the complex phase velocity . Numerical method The two Orr-Sommerfield equations eqs. (4) along with eight boundary conditions eqs. (5) are solved numerically using Pseudo-spectral Chebyshev collocation method[1,2]. To implement the Chebyshev method, we transformed each of the two fluid domains into standard Chebyshev domain that is Fluid 1 domain is mapped to and Fluid 2 domain is mapped to by substituting and respectively. Next, we represent each stream function as truncated summation of orthogonal Chebyshev polynomials by setting. and(6) Where and are unknown Chebyshev coefficients and N is the number of Cheyshev collation points in each domain. Upon substituting eq. (6) in eq. (4) and projecting them on to arbitrary orthogonal functions and respectively by taking the Chebyshev inner product, . these two Chebyshev inner products forms N-3 equations each summing up to 2N-6 equations and N+1 coefficients in and N+1 coefficients . 2N-6 equations along with 8 boundary conditions obtained by substituting eq. (6) in eq. (5) and 2N+2 coefficients forms a linear system Where, and,are square matrices of size 2N+2. This generalized eigen value problem was solved by QZ algorithm to obtain and subsequently growth rate, .We used, above which the eigen values are independent of number of collocation points. The accuracy of the Numerical method is checked by comparing current results with published literature[10] for the Two layer couette flow with an insoluble surfactant in stokes flow limit. To make this comparison, growth rates are calculated by muting the inertial terms by settingin the our code and with same parameters as in Halpern’s[10] Fig 2a and Fig 2b, where growth rates are predicted by long-wave evolution equation. Fig xxx shows excellent agreement between two numerical procedures. Figure 2: Dispersion curves for the most (a)Unstable Figure 3: Dispersion curve for the (solid line), (dashed line), at, ,, RESULTS and discussions Blyth and Pozrikidis[14] observed that in the Stoke’s flow limit, there exists two modes that govern the stability of a two-layer couette flow system with surfactant: the Marangoni mode and the Yih mode associated with surfactant and the clean liquid-liquid interface respectively. But on the other hand, in flows with inertia, there exists more than two normal modes. From Fig. 3, the broken line corresponding to is above the solid line, which corresponds to , it is evident that the surfactant in the presence of inertia has significantly reduced the rate at which small perturbations decay. Earlier stability analysis for stoke flow in presence of surfactant opens up a range of unstable wave numbers extending from zero up to the critical wavenumber .The neutral stability curve Fig. 4 for values (,, and ) is in accordance with the earlier stokes flow stability analysis and in addition at , a second small window of stable wave numbers appears to form an island of stable modes, wit h the island tip located at . In Fig. 5 we plot the growth rate of the Marangoni mode against the Reynolds number, up to and beyond, for , corresponding to the stable island tip. At, linear stability for Stokes flow predicts the growth rate, for the Marangoni mode. The present results confirms that the Marangoni mode at marks the inauguration of the lower stable loop. In Fig. 6 for a fixed Reynolds number , we show the dependence of the growth rates of the Marangoni mode on the wave number. The close-up near , presented in Fig. 6(b), shows that the Marangoni mode has negative growth rate for small band of wave numbers ranging from and has positive growth rate thereafter up-to , beyond which the Marangoni mode is stable again. These results clearly demonstrate the crucial role of the surfactant, which either provokes instability or significantly lowers the rate of decay of infinitesimal perturbations.

Exemplification Essay

Exemplification Essay I once heard a story about a restaurant manager named Jerry. Jerry was the type of guy that always was in a good mood no matter what. He was a natural motivator. When one of his employees would come in hating life he would be help them to look on the positive side of the situation. One of his other employees was curious, so one day he went up to Jerry and asked, â€Å"I don’t get it man, how can you be in a good positive mood all of the time. How do you do it? † Jerry replied, â€Å"Each morning I get up and I have a decision to make: to be in a good mood or to be in a bad mood. I choose to be in a good one. Every time something bad happens I can choose blame it on myself or I can choose to learn from the situation. † â€Å"It’s not that easy. † The employee protested. â€Å"Yeah it is. † Jerry said. â€Å"Life is all about the choices that you make and how you handle them, you choose to be in a good mood or to be in a bad mood. Bottom line: Attitude is everything. † The employee reflected on Jerry’s example. Later he left the restaurant business to start a business of his own. He lost touch with Jerry but would often use his teachings in his everyday choices in his life. A number of years later he heard that Jerry had left the back door open to his restaurant and he was robbed at gunpoint. While Jerry was opening the safe he was shaking and he slipped. One of the robbers, on edge, shot Jerry and they scurried away. Luckily, he wasn’t lying out for too long for an ambulance to come rush Jerry to the hospital; Jerry survived. Six months after the robbery the old employee met up with Jerry and had asked him about the incident. Jerry replied, â€Å"The Paramedics in the Ambulance were great. They kept on telling me that I was going to be fine until they handed me over to the doctors, that’s when I got worried. The doctors and the nurses eyes read that I was a dead man, not likely to survive. A nurse asked, â€Å"Do you have any allergies? †. I had a choice to make, to live or to die, to be in a good mood or a bad mood. â€Å"Yes† I replied to the nurse. The doctors stopped what they were doing waiting for my answer. â€Å"Bullets! † During their laughter they I told them â€Å"I’m not dead yet, make sure I don’t die. † Jerry lived by the outstanding skill of the doctors, but also due to his attitude. On July 19, 2011 my dad taught me the greatest lesson that I could ever be taught. Every year my paternal side of the family has a reunion in Capitol Reef National park, Southern Utah. My dad came up with the idea that we should leave a couple days earlier and ride our road bikes ahead of the rest of the family. Knowing me, he knew I was â€Å"in†. I just had had a friend move in with me because his family moved to Kentucky and he wanted to finish his senior year at our high school. He joined us on the ride. We started to do some training rides to get ready for the two hundred mile trek of which we were about to embark. July 19: woke up, ate a banana and oatmeal, got dressed in biking gear, took the first pedal and off we went. There were two different routes we could have taken: east of the lake or west of the lake. We chose to go west to avoid the traffic and the higher risk. When we reached the west side of the lake there was a head wind, so we started to draft off of each other. Every five minutes we would rotate who was in lead. It was my turn to lead, my dad following me, and my friend Kallen following him. Kallen’s headphones fell out of his ears and got wrapped up in his front wheels. While drafting he reached down to clear the remains of his headphones and his arm got sucked into the spokes which made him flip over the handle bars. I didn’t notice over the sound of my music that he had crashed but my dad did hear the accident and waved me down to go back. We frantically signaled a car down. A nice lady stepped out and offered to take Kallen to the hospital. My dad and I continued on our way. We reached the other side of the lake and I got a flat tire, which was my second for the day and I was already upset that we lost Kallen. We patched the flat and continued on our ride. Anger was just bottling up inside of me as we entered the next town. When we arrived we sat down to eat. It was about 3 o’clock and we still had seventy miles to go which added to my anger. After lunch we rode over to a park to use the public bathrooms. I take a short cut through a little dirt field. I used the restroom and hopped back on my bike to begin riding again and my tire was flat, again. â€Å"AHHH! †, I screamed. We went and sat on the grass to patch it. My attitude has not only has affected me, but has affected my dad too. â€Å"You better get in a better mood† he said†Ã¢â‚¬ ¦because you are acting like a little baby. You have a choice to make; be in a good mood or a bad one, because we are going to finish this ride whether you want to or not. † I was shocked. My dad had never talked to me like that before. I realized that attitude is everything. We rode into the dark that night till we reached one hundred and twenty miles and the next day we biked the remaining 80 and made it to Capitol Reef. July 19 is my birthday. It had to have been the worst but also the best birthday that I have ever had. Your attitude towards something can change your life. Whether it is as big as saving your life or as small as changing your mood such as finishing a biking trip with your dad. It will stick with you and make you a better person and a happy person. Bottom line: Attitude is Everything. Exemplification Essay Exemplification Essay I once heard a story about a restaurant manager named Jerry.

Anger was just bottling up inside of me as we entered the next town. When we arrived we sat down to eat. It was about 3 o’clock and we still had seventy miles to go which added to my anger. After lunch we rode over to a park to use the public bathrooms. I take a short cut through a little dirt field. I used the restroom and hopped back on my bike to begin riding again and my tire was flat, again. â€Å"AHHH! †, I screamed. We went and sat on the grass to patch it. My attitude has not only has affected me, but has affected my dad too. â€Å"You better get in a better mood† he said†Ã¢â‚¬ ¦because you are acting like a little baby. You have a choice to make; be in a good mood or a bad one, because we are going to finish this ride whether you want to or not. † I was shocked. My dad had never talked to me like that before. I realized that attitude is everything. We rode into the dark that night till we reached one hundred and twenty miles and the next day we biked the remaining 80 and made it to Capitol Reef. July 19 is my birthday. It had to have been the worst but also the best birthday that I have ever had. Your attitude towards something can change your life. Whether it is as big as saving your life or as small as changing your mood such as finishing a biking trip with your dad. It will stick with you and make you a better person and a happy person. Bottom line: Attitude is Everything.
