Mystery Substance Lab Write-Up
The haters always say, “Johnny, you’re bad at chemistry.” Well, this lab proved the haters wrong. Charlie and I were the first in our class to guess the mystery substance correctly, (we hope), and we did it while doing the fewest tests (we think). “That’s a weird brag,” the haters would say. I think they’re just jealous.
The goal of this lab was to find out as much as possible about the given mystery substance. Charlie and I did that, and more. As I said earlier, we were even able to identify with almost complete certainty what our substance was: ammonium acetate. In general, Charlie and I tried to be as thorough as possible with the tests without being redundant. For example, since we were certain that the substance was an acetate after doing a number of solubility tests, we decided not to do experiments that tested for a sulfate or something else of that nature. Besides trying to avoid redundancy, we also tried to maintain calm, even when a test didn’t go the way …show more content…
The first thing that we did was eliminate any substance whose melting point seemed far off from what ours was. It turned out that there was only one type of acetate that had a similar melting point to our mystery substance: ammonium acetate. Perhaps too quickly, we decided to ask Mr. Pojman for that substance. When Mr. Pojman came out with a substance that looked nothing like ours, I had a panic attack, but luckily he was just playing with us, and soon after he showed us what looked and smelled exactly like our substance. Finally convinced that we had guessed our substance correctly, we decided that we needed to prove it, beyond how it looked and smelled. We did the same solubility tests for the substance, and when we also checked the melting point again and got the same results, we were able to confirm that the substance was ammonium

Session Hijacking

...Preventing Session Hijacking in Cloud Computing Sasha Melanie Personal Research Paper 20th October 2015 Abstract The idea of Cloud processing is turning out to be a well-known concept every passing day particularly in the field of computing and information technology. It refers to both applications that are conveyed as administrations over the Internet and also as resources (software and hardware) in the data centres. With this kind of advancement, the cloud computing technology raises many security concerns. There are several vulnerabilities that come along with cloud computing that may be exploited by attackers through security threats such as session hijacking. This paper gives an overview of the cloud as well as session hijacking highlighting the key vulnerability areas that every organization need to put into consideration before any implementation of cloud computing.

Schizophrenia: an Examination

...Schizophrenia: An Examination PYC4802 Assignment 3: 668049 17 JUNE 2015 The El Index * Cover * Index * Introduction * Chapter 1: A Definition of Schizophrenia * Chapter 2: Symptoms of Schizophrenia * Chapter 3: Causes of Schizophrenia * Chapter 4: Treatment of Schizophrenia * Chapter 5: Living with Schizophrenia * Conclusion * References Chapter 1. Introduction Schizophrenia, or mental illnesses in general isn't something new. It isn't a new age ideal which popped up out of nowhere. Even in the time of the Egyptians, there were reported cases of mental illnesses, but back then, they did not have the knowledge that we do today, so as Yuhas (2013) states, they simply deemed that those who displayed the symptoms of mental illnesses, such as those who had issues with concentration, those who were delirious or those with dwindling attention spans as simply suffering from emotional distress. It's not just the Egyptians, though. As Nizamie and Goyal (2010) point out, the ancient Indian text known as the Atharva-Veda also speak of mental illnesses, but to them back then, they were simply divine afflictions and curses sent from the gods who were angry at those who suffered. They also go on to elaborate on the Atharva-Veda, revealing that in the ancient text, there were detailed descriptions of conditions which sound similar to both bipolar disorders and schizophrenia, with many...

All rituals, science, artwork, and monuments in this novel are real. ———————————— Prologue House of the Temple 8:33 P.M. The secret is how to die. Since the beginning of time, the secret had always been how to die. The thirty-four-year-old initiate gazed down at the human skull cradled in his palms. The skull was hollow, like a bowl, filled with bloodred wine. Drink it, he told himself. You have nothing to fear. As was tradition, he had begun this journey adorned in the ritualistic garb of a medieval heretic being led to the gallows, his loose-fitting shirt gaping open to reveal his pale chest, his left pant leg rolled up to the knee, and his right sleeve rolled up to the elbow. Around his neck hung a heavy rope...

...If this situation sounds familiar, you may find it reassuring to know that many professionals undergo these same strange compulsions before they begin writing. Jean Kerr, author of Please Don’t Eat the Daisies, admits that she often finds herself in the kitchen reading soup-can labels—or anything—in order to prolong the moments before taking pen in hand. John C. Calhoun, vice president under Andrew Jackson, insisted he had to plow his fields before he could write, and Joseph Conrad, author of Lord Jim and other novels, is said to have cried on occasion from the sheer dread of sitting down to compose his stories. To spare you as much hand-wringing as possible, this chapter presents some practical suggestions on how to begin writing your short essay. Although all writers must find the methods that work best for them, you may find some of the following ideas helpful. But no matter how you actually begin putting words on paper, it is absolutely essential to maintain two basic ideas concerning your writing task. Before you write a single sentence, you should always remind yourself that 1. You have some valuable ideas to tell your reader, and 2. More than anything, you want to communicate those ideas to your reader. These reminders may seem obvious to you, but without a solid commitment to your own opinions as well as to your reader, your prose will be lifeless and boring. If you don’t care about your subject, you can’t very well expect anyone else to. Have confidence that your ideas...
