Ebola in The Hotzone :: Ebola Hemorrhagic Fever

Back in 1980 a certain Frenchman resided near the slopes of Mount Elgon. Mount Elgon and its slopes are an island of vegetation surrounded by savannah. And at the center of this island, being part of the mountain, lies a certain large cavity, Kitum Cave. It is this cave that our Frenchman one day decided to visit, bringing a paid â€Å"friend† along with him. It is speculated that it was during this trip that our Frenchman first contracted the virus Ebola. A few days later he is not feeling well. He is suffering from headaches, fever, and pain behind his eyes. His appearance has become similar to one who has not slept in days. Eventually his coworkers began to worry about him, and upon finding him in such condition, sent him to the local hospital. The hospital was unable to cure him and was mystified. And so our Frenchman was sent to the more advanced hospital of Nairobi, traveling by public airways, likely making contact with many. Before his death at the Nairobi hospital, th e Frenchman managed to infect his doctor by vomiting upon him. Death was expected for the doctor, Dr. Musoke. However, after ten days after the event, his health began in improve and he managed to pull through. Ebola, a filovirus related to Marburg, had now become recognized by the modern world. Four years earlier in Sudan a worker of a cotton factory somehow contracted Ebola. He contracted the virus to a coworker, and from that coworker Ebola spread throughout and devastated parts of Sudan with a fatality rate of 50 percent. First, small clots would appear in the victim’s bloodstream, resulting in a slowed down and thickened bloodstream. Various parts of the victim’s body would lose their once constant and expected supply of blood. Skin begins to acquire spots of red which later develop bubbles of white blisters. The skin is now soft and pulpy and easily tears. The victim’s mouth is not spared from this fate. It begins to bleed painfully, the surface of the tongue as well as victim’s windpipe slough off and are later expelled from the body via vomit. The heart bleeds into itself, the brain clogs with dead cells, and the liver begins to turn to mush. Eyes turn red from blood and the face becomes a droop because of the loss of connective tissue. T he victim’s appearance is zombie like. Before death strikes, the victim begins a series of wild convulsions, spreading blood all over the place.

Congo :: essays research papers

Desperate Battle Defines Congo's Warlike Peace At the southern extreme of a ragged front line that winds 1,400 miles across Congo lies a ferry, dirty pink and half-submerged in the muddy Luvua River. Facing it on a gravel ramp stand the burned-out husks of 33 military vehicles -- armored personnel carriers, trucks, an ambulance -- waiting in a line that never moved forward. Unopened syringes lie underfoot, amid charred tires and a trampled note that a fleeing Congolese junior officer left behind: "Attaque," reads the neat cursive French. But by the time Rwandan forces approached Pweto on Dec. 3, the Congolese government army was in no position to attack. It was in panicked retreat, leaving a tableau of ruin on the riverbank and opening a rare window on a war usually fought out of sight. In two months of back-and-forth fighting here in the southeastern corner of Congo, all the elements that make this country's 21/2-year-old war such a dangerous puzzle came into play: foreign armies, ethnic militia groups, remote terrain and villages utterly emptied of civilians who, from the safety of refugee camps in a neighboring country, repeat matter-of-fact accounts of massacres. This is the "situation on the ground" that has kept the U.N. Security Council from dispatching 5,500 peacekeepers to monitor a cease-fire that appears to exist only on paper. This lightly populated, mostly forested stretch between Lake Tanganyika and Lake Mweru had been one of the few corners of Congo where both sides had essentially honored a peace agreement signed 18 months ago. The Lusaka Accord, named for the Zambian capital where it was signed, was meant to arrest the cycle of advance and retreat that has marked a sprawling conflict that pits the Congolese army and allied troops from Angola, Zimbabwe and Namibia against an assortment of rebel forces bolstered by Rwandan and Ugandan troops. But Congolese President Laurent Kabila, who signed the Lusaka pact in a moment of military disadvantage, has swept it aside whenever he spied what looked like a military opening. Last spring, his forces pushed back rebels sponsored by Uganda in Congo's far northwest, only to lose the same ground months later. And on Oct. 15, Kabila's armies launched a massive assault on Rwandan-held positions in the southeast, striking 100 miles north of Pweto at the town of Pepa. Six weeks later, just as happened in the northwest, Kabila's forces once again lost far more than they gained.

Mississippi Burning Essay

Mississippi Burning directed by Alan Parker is a film set in the mid 1960’s. It was set in the time of the Civil Rights Movement and throughout the film it is shown how badly coloured people were discriminated against during those times. The major theme in the film is racism and segregation between the white and the coloured people in Jessup County. The director has developed this theme by using different techniques such as having characters with different personalities and authority, by using various film techniques and by setting the film in a particular location. Parker explores the theme of racism through the characters. The two main characters in the film are Agent Rupert Anderson who is played by Gene Hackman and Agent Alan Ward played by Williem Dafoe. Agent Anderson is an older, wiser character and likes to investigate cases the way he was taught whereas Agent Ward is younger and likes to complete cases differently. For example, in the diner scene Agent Ward went and s at with the coloured people as there were no seats left in the white section but Agent Anderson didn’t follow. Other characters in the film are Deputy Pell (Brad Dourif) and Sheriff Stuckey (Gailard Sartain). These two characters discriminate against coloured people the most. Parker shows this by making the two characters rude and arrogant. Both Stuckey and Pell were part of the KKK who scared and killed black people to help with the segregation of the coloured and white people. (Rest of America don’t mean jack shit. You in Mississippi now. – Sheriff Stuckey.) Sheriff Stuckey said this because he believes that because he is in Mississippi the rules are different from those of other states in America. Parker used different film techniques throughout the film such as camera angles, music and different clothing worn by the characters. In the film Parker used camera angles such as extreme wide shot. An example of when extreme wide shot was used was at the start of the film when we see the car that the civil rights workers are in and then three cars behind them. Another angle used was close up, for example when Frank Bailey (Michael Rooker) shot the civil rights worker in the head. The last camera angle used was over the shoulder shot for example when Agent Ward and Agent Anderson are in the car. Parker used the over the shoulder shot to make us feel like we are also in the car they would shoot the camera over the shoulder of whoever the person was talking to. Another film technique used was music. To show that something bad was about to happen Parker in the background had low drum beats playing. For example, in the first few scenes where the cars were driving along the road Parker had the low drum beats playing to add suspense and to show that the civil rights workers were about to be killed. Another technique used in the film was the different clothing worn by the characters. To show how the coloured people were treated compared to the whites, the coloured people wore old and dirty clothes while the whites wore new, well-kept clothes. Agent Ward also wears a suit and with glasses to portray an image of him being serious and professional whereas Agent Anderson wore a short sleeved shirt with his tie loosely worn to portray an image of him being more laid back. The film was set in Jessup County, Mississippi in the 1960’s. To help show how badly segregation was in the 1960’s Alan Parker made many scenes where the coloured and white people were treated differently, for example, in the diner and the houses that the coloured and the whites lived in. In the diner scene, the coloured people had a separate place at the back where they were to eat because they didn’t deserve to eat in the same place as the white people. Also the coloured people had houses that were wooden and lived on farms whereas the white people had proper houses situated in the town. In conclusion, Alan Parker used many techniques to show racism throughout the film. The different techniques used to show the theme of racism were the personalities of the main characters, the camera angles and music chosen and the setting of the film.

Succubus Blues CHAPTER 16

â€Å"Georgina?† â€Å"I'm still here.† â€Å"Pretty fucked up, huh? I guess this kills your angel theory.† â€Å"I'm not so sure.† My initial feeling of dismay was being replaced by a new idea, one that had been percolating in the back of my mind ever since I read the biblical passage at Terry and Andrea's. I wondered now†¦ wondered exactly what we were dealing with, if it was an angel after all. The words in Genesis came back to me: There were giants in the earth in those days†¦ the same became mighty men which were of old, men of renown†¦ â€Å"What's Jerome saying about all of this?† â€Å"Nothing. What'd you expect?† â€Å"Everyone else is okay, though?† â€Å"Fine, last I knew. What are you going to do? Nothing stupid, I hope.† â€Å"I have to go check on something.† â€Å"Georgina†¦Ã¢â‚¬  Hugh warned. â€Å"Yeah?† â€Å"Be careful. Jerome's in a terrible mood over all of this.† I laughed harshly. â€Å"I can imagine.† An awkward silence hung on the line. â€Å"What else aren't you telling me?† He hesitated a moment longer. â€Å"This†¦ this is a surprise to you, right? This Lucinda thing?† â€Å"Of course it is. Why wouldn't it be?† Another pause. â€Å"It's just†¦ well, you've got to admit it's kind of weird, first Duane†¦Ã¢â‚¬  â€Å"Hugh!† â€Å"And then, I mean, when no one could contact you†¦Ã¢â‚¬  â€Å"I told you, my cell phone broke. You can't be serious about this.† â€Å"No, no. It's just†¦ I don't know. I'll talk to you later.† I disconnected. Lucinda dead? Lucinda, with her plaid skirt and bob? It was impossible. I felt terrible; I'd just seen her the other day. Sure, I'd called her a sanctimonious bitch, but I hadn't wanted this. Any more than I'd wanted Duane dead. Yet, the connections Hugh had drawn were weird, weirder than I liked to admit. I'd argued with both Duane and Lucinda, and they'd died shortly thereafter. But Hugh†¦ how did he fit in? Some friend. From what I heard, he received a great deal of amusement telling anyone that would listen about your little whip and wings getup. I remembered Luanda's jibe. I had indeed had a small flare-up with the imp just before his attack. A small flare-up and a small attack, considering he had lived. I shivered, unsure as to what this meant. Doug walked in. â€Å"You get everything straightened out?† â€Å"Yeah. Thanks.† We stood there uncomfortably for a moment until I finally unlocked the floodgates of my guilt. â€Å"Doug, I-â€Å" â€Å"Forget it, Kincaid. It's nothing.† â€Å"What I said, I shouldn't have. I was – â€Å" â€Å"Wasted. Trashed. Flat on your ass drunk. It happens.† â€Å"Still, I had no right. You were trying to be nice, and I turned complete psycho bitch on you.† â€Å"You weren't that psycho.† â€Å"But definitely a bitch?† â€Å"Well†¦Ã¢â‚¬  He hid a smile, not meeting my eyes. â€Å"I'm sorry, Doug. I'm really sorry.† â€Å"Quit it. I can't take much more of this sentimentality.† I leaned over and squeezed his arm, resting my head slightly on his shoulder. â€Å"You're a good guy, Doug. A really good guy. And a good friend. And I'm sorry†¦ sorry for a lot of things that have – or haven't – happened between us.† â€Å"Hey, forget about it. It's nothing between friends, Kin- caid.† A pregnant pause hung between us; he was still clearly uncomfortable with this exchange. â€Å"Did†¦ did everything turn out all right? I lost track of you after the show. That outfit you have on doesn't reassure me any.† â€Å"You'll never believe whose shirt this is,† I teased, subsequently telling him the whole tale of getting sick with Seth and the follow-up birthday party. Doug was pushing hysterics by the time I finished, albeit in a relieved sort of way. â€Å"Mortensen's a good guy,† he finally said, still laughing. â€Å"He says the same thing about you.† Doug grinned. â€Å"You know he's – oh, man. I forgot, what with all those phone calls.† Turning to the desk, he sifted through papers and books, finally producing a small white envelope. â€Å"You got a note. Paige said she found it last night. I hope it's good news.† â€Å"Yeah, me too.† But I had my doubts when I saw it. I took it gingerly, like something that might burn me. The paper and calligraphy were identical to the last one's. Opening up the envelope, I read: So you're interested in fallen angels, are you? Well, there'll be a hands-on demonstration tonight. It should prove more informative than your current endeavors and won't require you screwing your boss in order to get help with extrapolation – not that watching you make a whore of yourself didn't have its moments. I looked up, meeting Doug's curious eyes. â€Å"No worries,† I told him lightly, folding the note up and placing it in my purse. â€Å"This is old news.† Hugh's report implied Lucinda had been killed last night, and this note had been slipped to me beforehand, according to Doug. The warning had gone unheeded. This person apparently didn't have a good grasp of my schedule, or they hadn't wanted me to actually act beforehand. It was more like a scare tactic. Whatever their point in giving me a heads-up on Lucinda, it was nothing compared to the other reference in the note. The thought that someone had watched me have sex with Warren made my skin crawl. â€Å"Where are you off to now?† Doug asked. â€Å"Believe it or not, I need to find a book.† â€Å"You're in the right place.† We went back out to the information desk, where Tammi stood. It pleased me to see Doug training her in this post; we'd need people available for all jobs when the holidays came. â€Å"Practice time,† I told her. â€Å"Tell me where we keep this book.† I gave her the name, and she looked it up in the computer, frowning at the results. â€Å"We don't. We can order it for you.† I scowled, suddenly understanding why people seemed so pissed off when I told them that. â€Å"Great,† I muttered. â€Å"Where am I going to get it tonight?† Erik probably stocked it, but he'd be closed by now. â€Å"I hate to recommend this,† joked Doug, â€Å"but a library might have it.† â€Å"Maybe†¦Ã¢â‚¬  I eyed a clock, unsure how late the local branches stayed open. â€Å"Um, Georgina?† began Tammi carefully. â€Å"I know a place that has it. And that's still open.† I turned to her in surprise. â€Å"Really? Where – no. No. Not there.† â€Å"I'm sorry.† Her blue eyes pleaded with me to forgive her for such tidings. â€Å"But there were three copies in stock the last time I was there. They couldn't have sold out.† I groaned, rubbing my temples. â€Å"I can't go in there. Doug, you want to run an errand for me?† â€Å"I've got to close,† he admonished. â€Å"What place are you avoiding?† † Krystal Starz, home of ‘freaky witch woman.' â€Å" â€Å"You couldn't pay me to go there.† â€Å"You could pay me,† noted Tammi, â€Å"but I'm closing too. If it makes it any easier, she's not there all the time.† â€Å"Yeah,† added Doug helpfully. â€Å"No manager is always on-duty. She must have other staff to cover her.† â€Å"Unless they're short-staffed,† I muttered. The irony. I left the store and got into my car for the journey to Krystal Starz. As I drove, I reflected on the two pieces of information I'd gleaned today. First, the nephilim reference. The King James translation had mentioned angelic offspring, even mentioned them as being abnormal, but I had never considered the possibilities half-angel children might present. The annotation in Terry and Andrea's translation had elaborated only slightly more on such creatures, but it had been enough to spring a lock in my head. Who better, I thought, to take on both angels and demons than some sort of bastard demigod? Of course, the whole discovery of the nephilim had come about as a spin-off to the verse Erik had given me about fallen angels. I could be running away with a blind lead here when really the culprit was just a regular immortal, albeit an unstable one, slaying members of both sides. After all, I still hadn't ruled Carter out of the realm of suspects, nor had I figured out why said killer would finish the job with Duane and Lucinda but let Hugh live. My other piece of data today, the new note, offered little I hadn't already known. I'd simply found it too late for it to be of preemptive use. And if some voyeur was following me around, there was nothing I could do about that either. Yet, it led to the obvious question: Why was this person following me around? Evidence suggested I was the only one receiving such attention, the only one receiving notes. And again, there was the niggling truth: Everyone I'd fought with had later become a victim†¦ When I had almost reached Krystal Starz, I pulled off onto a deserted street. Unbeknownst to Tammi and Doug, I already had a simple solution for facing Helena. Stripping out of the dress and Seth's shirt, lest they be consumed, I shape-shifted, taking on the guise of a tall, willowy Thai woman in a linen dress. I sometimes used this body to hunt in. The New Age bookstore was quiet when I entered, with only a couple of browsing customers. I saw the same boyish acolyte from before manning the register, and blessing upon blessing, I couldn't see Helena anywhere. Even disguised, I still had no desire to run into that nutcase. Smiling at the young man behind the counter, I approached and asked where I could find the book. Grinning back like an idiot – this was a very attractive form, after all – he led me to a certain section in their cryptic cataloging system, immediately finding the book. As Tammi had said, the store stocked three copies. We returned to the register to cash out, and I sighed in relief, thinking I was going to make it out of here unscathed. No such luck. The back door leading to the conference room opened, and Helena glided out as though conjured, clad in a flowing fuchsia gown, laden with her usual ten pounds of necklaces. Damn it. It was like the woman really did have a sixth sense or something. â€Å"Things are well, Roger?† she asked the clerk, using her raspy show voice. â€Å"Yes, yes.† He bobbed his head eagerly, apparently thrilled that she'd call him by first name. Turning to me, she gave me one of her diva smiles. â€Å"Hello, my dear. How are you this evening?† Remembering that this persona had no grudge with her, I forced a smile and answered politely, â€Å"Good, thank you.† â€Å"I imagine so,† she told me gravely as I handed cash to the boy, â€Å"because I sense excellent things about your aura.† I widened my eyes in what I hoped was a laywoman's awe. â€Å"Really?† She nodded, pleased at an appreciative audience. â€Å"Very bright. Very strong. Lots of color. You have good things in store for you.† This message was a far cry from the one she'd given me at Emerald City, I thought. Seeing my book, she eyed me sharply, probably because it was dense and filled with research, as opposed to most of the fluff she sold. â€Å"I'm surprised. I would have expected you to be reading up on how to focus your gifts more. Maximize your full potential. I have several titles I can recommend if you're interested.† Didn't this woman ever stop with the sales pitching? â€Å"Oh, I'd love to,† I oozed back, â€Å"but I only brought enough cash for this.† I gestured to the bag now in hand. â€Å"I understand,† she told me gravely. â€Å"Let me show you anyway. So you'll know what to come back for next time.† Torn, I contemplated which would cause me the most discomfort: going along with her or starting a feud in yet another body. Noticing a clock, I saw that the store closed in fifteen minutes. She couldn't waste that much of my time. â€Å"Okay. I'd love to.† Beaming, Helena led me across the store, another victim in her thrall. As promised, we looked at books on utilizing the strongest parts of the aura, a few books on crystal channeling, and even one on how visualization could help bring about the things we most wanted. This last one was so painful, I wanted to beat myself in the head with it to end my suffering. â€Å"Don't underestimate the power of visualization,† she whispered. â€Å"You can control your own destiny, set your own paths, rules, and stakes. I can sense great potential in you, but following these principles can help you unlock more – all the things you'd want for a happy and fulfilling life. Career, home, husband, children.† An image of Seth's niece curled in my lap suddenly came unbidden to me, and I hastily turned away from Helena. Succubi bore no children. No such future waited for me, book or no. â€Å"I need to go. Thanks for your help.† â€Å"Of course,† she responded demurely, handing me a list she'd conveniently written the titles – and prices – upon. â€Å"And let me give you some brochures for our upcoming programs and events.† It didn't end. She finally released me once I was sufficiently laden with paper, all of which I dumped into the trash bin in the parking lot. Lord, I hated that woman. I supposed Helena the schmoozing con artist was better than Helena the raving lunatic who had been at Emerald City, but really, it was a tough call. At least I'd obtained the book, which was all that mattered. I pulled off at one of my favorite Chinese places on the way home, back in my normal shape. Carrying Harrington's book in, I ate General Tso's chicken while reading the entry on nephilim : Nephilim are first referenced in Genesis 6:4, where they are sometimes referred to as â€Å"giants † or â€Å"fallen ones.† Regardless of the word's translation, the nephilim's origin is clear from this passage: they are the semi-divine offspring of angels and human women. Genesis 6:4 refers to them as â€Å"mighty† and â€Å"men of renown.† The rest of the Bible makes little reference to the nephilim's angelic siring, but encounters with giants and men of â€Å"great stature† are frequently recorded in other books, such as Numbers, Deuteronomy, and Joshua. Some have speculated that the â€Å"great wickedness† prompting the flood in Genesis 6 was actually a result of the nephilim's corrupting influence on mankind. Further apocryphal readings, such as 1 Enoch, elaborate on the plight of the fallen angels and their families, describing how the corrupted angels taught â€Å"charms and enchantments† to their wives while their offspring ra n wild throughout the earth, slaughtering and causing strife among humans. The nephilim, gifted with great abilities much like those of the ancient Greek heroes, were nonetheless cursed by God and neglected by their parents, consigned to wander the earth all their days without peace until eventually destroyed for the sake of mankind. I looked up, feeling breathless. I had never heard of anything like this. I had been right in telling Erik practitioners were the worst to ask about their own histories; surely this was something someone should have told me about before. Angelic offspring. Were nephilim real? Were they still around? Or was I really just chasing a dead end here, following a distracting lead when I should have restricted my search to immortals of my caliber or above, like Carter? After all, these nephilim were half-human; they couldn't be all that powerful. After paying the bill, I walked out to my car, opening my fortune cookie as I went. It was empty. Charming. A light rain misted around me, and fatigue crept in around my edges, not surprising considering the last twenty-four hours. I couldn't find a parking spot when I arrived in Queen Anne, which indicated some sort of sporting event or show going on nearby. Grumbling, I parked seven blocks away from home, vowing to never again lease an apartment that only had street spots. The wind Seth and I had felt earlier was fading, normal since Seattle was not a wind-prone city. The rain picked up in intensity, however, further darkening my mood. I was halfway home when I heard footsteps behind me. Pausing, I turned to look back but saw nothing save slick pavement, blearily reflecting streetlights. No one was there. I turned back around, starting to pick up my pace until I did a mental head slap and simply turned invisible. Jerome was right; I did think like a human too much. Still, I didn't like the street I'd chosen back; it was too deserted. I needed to cut over and walk the rest of the distance on Queen Anne Avenue itself. I had just turned the corner when something impacted me hard on my back, knocking me forward six feet, startling me so much that I shifted back to visible. I tried to turn around, flailing at my attacker, but another blow hit me in the head hard, knocking me to my knees. The sense I had was of being struck by something hand and arm shaped, but it packed a punch, more like a baseball bat. Again, my attacker hit me, this time across one of my shoulder blades, and I cried out, hoping someone would hear me. Another strike swiped the side of my head, the force pushing me over onto my back. I squinted up, trying to catch sight of who was doing this, but all I could dimly discern was a dark, amorphous shape, bearing down on me fast and hard as another blow made contact with my jaw. I could not get up from that onslaught, could not fight against the pain descending on me harder and thicker than the rain around me. Suddenly, brilliant light filled my vision – light so brilliant it hurt. I was not alone in my assessment. My attacker recoiled, letting me go, and I heard a strange high-pitched scream emitted above me. Attracted by some irresistible lure, I looked toward the light. A white-hot pain seared my brain as I did, my eyes taking in the figure moving toward us: beautiful and terrible, all colors and none, white light and darkness, winged and armed with a sword, features shifting and indiscernible. The next scream I heard was my own, the agony and ecstasy of what I had seen scorching my senses, even though I could no longer see it. My vision had gone white-whiter-whitest until all was black, and I could see nothing at all. Then, silence fell. I sat there sobbing, hurting physically and spiritually. Footsteps came, and I felt someone kneel beside me. Somehow, despite my blindness, I knew it was not my attacker. That person had long since fled. â€Å"Georgina?† a familiar voice asked me. â€Å"Carter,† I gasped out, throwing my arms around him.

An Evolution Of The Atomic Theory

An Evolution Of The Atomic Theory The atomic theory has advanced since the discovery of radioactivity in 1898. And so much of modern technology is based on these advancements. They couldn’t have happened without the discovery of electrons (e-), protons (p+), and neutrons (n0) through experiments done by four key scientists. Atomic theory starts to develop in 1897 when J. J. Thomson discovered the e- through his cathode ray experiment. In this experiment (figure one) he had a partially evacuated tube (a) with a cathode (b) and an anode (c) attached at each end. The cathode and anode were hooked up to a power source with the cathode being negative and the anode being positive. An electrical shock was sent through the cathode and it emitted negative cathode rays that traveled in a straight line (d). But when a positive magnet (e) was placed next to the rays, the rays deflected toward the positive magnet (f), proving they are negative because opposites attract. Another important discovery in atomic theory is protons. In 1910 at the University of Chicago a scientist named Rutherford was puzzled over the structure of the nuclear atom. J.J. Thomson had suggested a â€Å"plum pudding model† (Figure 2) of the nuclear atom where the atom is a ball of positive charge with e- stuck in it, but Rutherford wanted to put this theory to the test, so he conducted the gold foil experiment (Figure 3). There was a round florescent screen set up with a radioactive source at the entrance. From the radioactive source Rutherford fired ÃŽ ±- partials at thin gold foil. He expected them to all go through with minor deflections but this wasn’t the case. (Figure 4) He observed some particles moving off course from the straight line he assumed them travel, and some particles being bounced back altogether. From this observation came the conclusion that when a particle comes extremely close to where all the positive charge is located, it will move off co urse and when it hits this core it will deflect back. Rutherford called the core he found the nucleus which also makes up most of the mass of an atom and consists of protons. He found (figure 5) that the nucleus is surrounded by positive charge and has e- particles stuck in it. In 1911 Millikan was back on the job of electrons. Thomson had proven what the mass/charge of a e- was, he wanted to determine what the actual charge on each particle was. To do this he created the oil droplet experiment (Figure 6). Oil drops were sprayed into a chamber will a very tiny hole at the bottom. When an oil drop passed through the hole it was observed through a microscope and zapped with an x-ray that removed all air particles from it. The positive charge given through the plate above the particles was manipulated and monitored so the scientist could see how much positive charge it took to balance the negative charge underneath and the positive charge above and make the oil suspend in mid-air. From this they could determine the negative charge on an electron. Another thing that stumped Rutherford was why the atomic mass was larger than the combined mass of protons and electrons in a substance. He proposed that it was because of a neutral particle, but never did any experiments to prove this. In 1932 Chadwick took on the challenge and designed an experiment (Figure 7) where he fired ÃŽ ±- partials at a beryllium target. This then emitted particles that were allowed to fall onto paraffin wax, then releasing more particles, protons. From energy calculations he saw that the particles released from beryllium, as a result of the arrival of ÃŽ ±- partials on it, are uncharged and have essentially the same mass as protons, he called them neutrons. Without these important advances in atomic theory, it would be still assumed that the atom is the smallest particle of matter. Technology would be stuck in 1803 with John Dalton’s theory, and until a scientist came along with an experiment as brilliant as these, there would not be modern technology or a understanding of science as current as the one today.

Passenger Load Factor - Research Paper Example All the companies that exist and are stable, have this kind of management for it makes a company or an organization’s operations to work within the expected lines. Without this kind of operation, the company or organization cannot make any step both economically and financially. Operation management is also important in other fields a part from companies and organizations. This therefore makes it a global matter hence referred to as global operation. Operation caters for the risks and success made by the company. Just like any other moving machine with an engine, various organizations believe in operational management for it propels the company toward the desirable direction. At times this kind of operation can lead an organization or company to a path that is full of risks and this may be due to poor management by various unskilled personnel. Global operation forms the basis for all other operations that exist within any kind of management Global operations serve an important role to various running institutions in the world. It organizes, coordinates and controls the steps made by an organization or company towards any kind of direction. This is to ensure that the company arrives at ideal decisions and all its programs are set in a manner that can lead to success.

Journal Summary 2 - Research Paper Example In his article Aversano attempts to explore the reality of dream in human existence in the context of art and aesthetics. In the paper â€Å"Bad Dreams Are Made Of This† Leo Dolias has explored â€Å"bad dreams† from an existential perspective. While siding with Boss’s theoretical perspective of dream he thoroughly compares his own existential approach with Freud and Jung’s psychoanalytical view. Since, for Dolias, traditional Freudian view of dream often falls short to explain the experiences of bad-dreams, psychoanalysts need to add an existential dimension with Boss’s theoretical approach to dream, as he says, â€Å"I also intend†¦to bring experience and theory closer together, to allow for a creative interaction between theory, Heidegger’s philosophy, my views and experiences† (Dolias, 2010, p. 238).

Rather than being a â€Å"subject-object interrelation†, the process of being itself is the â€Å"dreaming reality† of an individual.

It further implies that her dreaming self is essentially her anxious being, which remains away in her waking state. This dreaming self of Martha basically refers to Heidegger’s Dasein. Since Martha’s Dasein determines her being on a journey in an ominous environment, this anxious Dasein reveals itself fully in her state. (Dolias, 2010) In the article â€Å"The
