...Clostridium Difficlie (C diff) Clostridium Difficlie, also known as C diff, is a bacterium infection that has symptoms of diarrhea but can also have life threatening inflammation of the colon (staff, 2012). C. diff most commonly affects older adults primarily those that are hospitalized or in a long term care setting (staff, 2012). “An epidemic of Clostridium difficle in the United States is now killing some 12,000 patients annually, in part because neither alcohol rubs nor soap and water used in the vast majority of hospitals can effectively remove the spore-forming bacillus from the hands of health care workers, researchers are finding” (Hand hygiene woes impact C.diff response, 2010,pg 76).Let’s explore Clostridium difficle a little, how it is transmitted, the environmental factors, standard treatments and ways to help prevent the spread of Clostridium Difficlie. Clostridium Difficlie bacteria are passed in feces and thru food, they are also on surfaces or objects where people fail to wash their hands when they are infected. These bacteria spores can last in a room for weeks or even months so if you touch an infected surface you can unknowingly ingest the bacteria (staff, 2012). Normally healthy people don’t get sick from the bacteria because your body contains many types of bacteria that will fight off the infection. However, many people get C. diff following a treatment with antibiotics. “The antibiotics that most often lead to C. difficle infections include fluoroquinolones...

...Clostridium difficile, or C-diff is a bacterial infection that causes severe inflammation to the colon. About 500,000 Americans develop Clostridium difficile and 14,000 of those people die. Due to this it is a serious problem. Many expensive antibiotics have been used to cure this disease, but they failed. Canadian researchers discovered a new way to hopefully cure C-diff. They found a safe and healthy to put people’s “poop” into pills. This method was used in 27 patients, all of them were cured. These fecal transplants only come from healthy, well suited donors. The poop restores good bacteria to the patient's body which destroys the infection and prevents future infections. There really isn't poop in these pills, just the bacteria, which...

...Delta encoding Delta encoding is a way of storing or transmitting data in the form of differences between sequential data rather than complete files; more generally this is known as data differencing. Delta encoding is sometimes called delta compression, particularly where archival histories of changes are required (e.g., in software projects). The differences are recorded in discrete files called "deltas" or "diffs", after the Unix file comparison utility, diff. Because changes are often small – for example, changing a few words in a large document, or changing a few records in a large table – delta encoding greatly reduces data redundancy. Collections of unique deltas are substantially more space-efficient than their non-encoded equivalents. From a logical point of view the difference between two data values is the information required to obtain one value from the other – see relative entropy. The difference between identical values (under some equivalence) is often called 0 or the neutral element. A good delta should be minimal, or ambiguous unless one element of a pair is present. Simple example Perhaps the simplest example is storing values of bytes as differences (deltas) between sequential values, rather than the values themselves. So, instead of 2, 4, 6, 9, 7, we would store 2, 2, 2, 3, −2. This is not very useful when used alone, but it can help further compression of data in which sequential values occur often. IFF 8SVX sound format applies this encoding to raw...

...for much more then ten years. At the core, there is little more to it then finally applying the good programming principles which we have been taught for more then twenty years. C++ (Eiffel, Oberon-2, Smalltalk ... take your pick) is the New Language because it is object-oriented — although you need not use it that way if you do not want to (or know how to), and it turns out that you can do just as well with plain ANSI-C. Only object-orientation permits code reuse between projects — although the idea of subroutines is as old as computers and good programmers always carried their toolkits and libraries with them. This book is not going to praise object-oriented programming or condemn the Old Way. We are simply going to use ANSI-C to discover how object-oriented programming is done, what its techniques are, why they help us solve bigger problems, and how we harness generality and program to catch mistakes earlier. Along the way we encounter all the jargon — classes, inheritance, instances, linkage, methods, objects, polymorphisms, and more — but we take it out of the realm of magic and see how it translates into the things we have known and done all along. I had fun discovering that ANSI-C is a full-scale object-oriented language. To share this fun you need to be reasonably fluent in ANSI-C to begin with — feeling comfortable with structures, pointers, prototypes, and function pointers is a must. Working through the book you will encounter all the newspeak — according...

...Object oriented programming refers to a method of programming in which individual objects, usually called "methods" and "functions", are created and used in junction with each other to perform a function. These objects are organized within the program through use of things called structures or classes. A class is something we use to create a blueprint of sorts for a assortment of variables and components. Similarly, a structure serves the same purpose. The only difference between a structure and a class is that a structure's members are public by default and a classes members are private by default. Another form of "blueprint" used by programmers is the data union. While a union is very primitive in comparison to a structure or class, it is a good tool to use to conserve memory in larger applications. A union uses the same memory block for multiple variables at different points. While two variables in a union cannot be accessed at the same time, a union is a good way to re-use blocks of memory that would normally be left void after a variable is finished with. Now that I have covered the basic points of classes, structures and unions, I will go into more detail of just how powerful a class or structure can be. In basic reference, a class is simply a blueprint to something we create instances of later in the program. This is a very vague statement however, because in object-oriented programming the class is the backbone of the program. It is what makes the...

...To: Rosemary Worth From: Re: misplaced trust on Kate Hoffman causing money loss issue Date: September 17, 2012 This memo is in response to your questions concerning money loss issue raised by Kate Hoffman and any related operating problems. After an in depth study of your company’s daily operation procedure and a situation that you are unable to step in a managerial role because of family responsibilities, I suggest you hire a new manager to take care of daily operation management, focus on 3-4 popular classes, shorten opening hours, and base commissions on performance. My suggestion is based on obtaining better management controls in the following three aspects. People Controls You trust Kate Hoffman so much that you let her take multiple tasks such as marketing, facility up-keeping, scheduling of appointments and record keeping. Kate was paid a salary plus a commission based on gross revenues just as other instructors. Kate might have thought that she did more work than other instructors and deserved more commission. When her expectation was not met, she lacked the motivation to handle multiple tasks and turned to an unethical way – stealing money from unrecorded revenue. If a new manager is hired, Kate can be released from administrative work and concentrate on her instructor job. Thus, further money loss can be avoided, and you can still keep the friendship between Kate and you as before. Furthermore, the newly hired manager can take place of the part time clerical...

...Reusability of Code To be able to compare and contrast procedural programming modules and object-oriented programming, or OOP for short, we need to understand the two different styles. Procedural programming was the most commonly used programming language early on with a top-down model. This programming module places its attention on procedures or actions, which take place within the program. A few examples of procedural programming are FORTRAN and BASIC. OOP although has become the preferred method of use. OOP focuses on objects, which are self-contained unit containing date and data operations. When it comes to the reusability of codes OOP makes this task much easier. As procedural programming is a line-by-line programming style as if to be writing out simple instructions. OOP however allows the programmer to utilize inheritance. Inheritance gives the programmer the ability to create new classes, known as subclasses, based on an existing class, known as the superclass. This ability enables the programmer to utilize the data and methods of the original class or superclass. This whole process is where the programmer is able to utilize code that already was written saving them time and eliminating the opportunity for programming errors. Another benefit to OOP over procedural programming is security and the ability to hide code. Within OOP, the programmer is able to label certain data fields as private. Once these data fields are labeled as private, their data and methods...

...ArrayList Johnnie L. Bagley III PRG/420 October 09, 2013 Dr. Orenthio K. Goodwin ArrayList The differences between the Array and an ArrayList is a common question asked by beginners, just starting to code using Java. The Array and ArrayList are both used to store elements, which can be a primitive or an object in the case of ArrayList in Java. A main difference between the ArrayList and an Array in Java would be the static nature of the Array, but the ArrayList has a dynamic nature. Once an Array is created, programmers cannot change the size of it, but an ArrayList will be able to re-size itself at any time. There is one more notable difference between ArrayList and an Array (Paul, 2012). The Array is a core part of Java programming that has a special syntax and a semantics support within Java. An ArrayList is a part of the collection framework of popular classes, such as HashMap, Hashtable, and Vector. There are six more differences between Array and ArrayList which will be listed in numeral order: 1. First and Major difference between Array and ArrayList in Java would be that Array is a fixed length data structure, while ArrayList is a variable length collection class. 2. Another difference is that an Array cannot use Generics, due to it cannot store files, unlike the ArrayList that allows users to use Generics to ensure storage. 3. Programmers can compare the Array vs. ArrayList on how to calculate length of Array or size of an ArrayList. 4....
