Seashell cs 136

Mode of decay: Beta and gamma radiation. Chemical properties: Liquid at room temperature, but readily bonds with chlorides to form a powder. Cs is used in small amounts for calibration of radiation-detection equipment, such as Geiger-Mueller counters.

In larger amounts, Cs is used in medical radiation therapy devices for treating cancer; in industrial gauges that detect the flow of liquid through pipes; and in other industrial devices to measure the thickness of materials, such as paper, photographic film, or sheets of metal. Cs is produced by nuclear fission for use in medical devices and gauges. Cs also is one of the byproducts of nuclear fission processes in nuclear reactors and nuclear weapons testing.

Small quantities of Cs can be found in the environment from nuclear weapons tests that occurred in the s and s and from nuclear reactor accidents, such as the Chernobyl power plant accident inwhich distributed Cs to many countries in Europe. Because it readily bonds with chlorides, Cs usually occurs as a crystalline powder, rather than in its pure liquid form. Small amounts of Cs are incorporated into Lucite disks, rods, and seeds. Larger Cs sources are enclosed in lead containers such as long tubes that are closed at each end or small round metal containers.

If the lead containers of Cs are opened, the substance inside looks like a white powder and may glow. Cs from nuclear accidents or atomic bomb explosions cannot be seen and will be present in dust and debris from fallout.

Small amounts of Cs are present in the environment from weapons testing in the s and s, so people are exposed to some Cs every day. However, Cs is dangerous in the large, concentrated amounts found in radiation therapy units and industrial gauges.

The sources in these devices are designed to remain sealed and keep people from being exposed; however, if these canisters are intentionally or accidentally opened, the Cs inside could be dispersed. External exposure to large amounts of Cs can cause burns, acute radiation sicknessand even death.

Exposure to Cs can increase the risk for cancer because of exposure to high-energy gamma radiation. Internal exposure to Cs, through ingestion or inhalation, allows the radioactive material to be distributed in the soft tissues, especially muscle tissue, exposing these tissues to the beta particles and gamma radiation and increasing cancer risk.

Radioisotope Brief: Cesium Cs Minus Related Pages. Half-life: Recall from Section 06 that a sequence is a Collection ADT that can store an arbitrary number of items. The picture below illustrates some of the behavior of a sequence ADT.

Please note how adding green items can shift some existing items red to the right, while others remain at their index gray ; likewise, removing items can shift some existing items yellow to the left, while again others remain at their index gray. We are not yet at the point where we can write our own complete ADTs in C.

We have provided an implementation of a sequence ADT that can store integers. There are already several functions in the main. In this question, we will cover a whole range of computer science and electrical engineering topics. Buckle up! We don't expect you to read, let alone understand the links above. Nonetheless, we wanted to share them with you because they contain some really neat foundational information. Now, these gates are important for this question because gates implement operators in Boolean algebra which finally brings us back to a topic we are all familiar with!

We call the last four gates "complex" because they can be expressed using a combination of the three basic gates. Once we can simulate gates and their Boolean algebra, we can combine them together to implement integer algebra.

We will focus on integer addition in this assignment question. Even a full-adder can only compute the sum of two 1-bit integers. Since the full-adder, however, allows for carry input as well as carry output, we can now chain multiple full-adders together.

This will allow us to add integers of arbitrary bit count. The goal of this question is threefold: simulating gates, the hardware building blocks of Boolean algebra; simulating basic adders, which use gates to perform addition of binary values, i.

In addition, we will practice the use of modules since the implementation of binary values, gates, and adders are split between multiple libraries. Only attempt it if you have some spare time and are curious about integrated circuit design. For us, a C-program is syntactically correct if there is a closing grouper for each opening one. In addition, groupers have to be balanced, i. You do not need to do anything for this question. By having this question, we want to let you know that one or more of the questions on this assignment will be hand-marked for coding style and the quality of your tests.

We are not stating which question s because you should use proper style and testing on all questions. Toggle navigation.

The questions are listed in approximate course chronological order, not necessarily in order of their difficulty or the amount of effort required. None of our private tests will intentionally cause an integer overflow. This library contains the tracing-tools as well as the symbol tools. The order within seq is the same as the order in which the integers were read. We do not care about runtime complexity at the moment, so your code does not have to meet any efficiency standards.

It has to terminate within the SeaShell timeout period, though. You can assume that we will not test your algorithm with more than items stored in a sequence. Question 2: Modules, Binary Arithmetic, and Integrated Circuitry [30 marks correctness] In this question, we will cover a whole range of computer science and electrical engineering topics.

This module implements a general ripple-carry adder, i. Your implementation only has to support binary numbers up to four bits in length as input. GOLD QUESTION no collaboration allowed [q3b-stackin-doubles] Write a program that reads in characters from input, and prints them in their original order, then in reverse order, then in their original order again, and then finally one more time in reverse order.Seashell SS-1, the planets first universal waterproof camera housing.

This necessitates the use of computational models for both Scheme and C that more closely resemble what happens in actual implementations. The goal of CS is to give students the tools and concepts necessary to solve computational problems in a robust, efficient and verifiable manner.
