4.1 Edit Data and Update Changes That Are Made to an ADO.NET DataSet Object Listing and viewing data is easy. What you really need to do is to be able to edit and update data. You know you can use the DataSet object and some of its objects and methods to perform this task. How do you edit and update data using the DataSet object? Technique In this How-To, you will use the DataAdapter, DataSet, DataTable, and DataRow objects. You have experienced some of the properties and methods of each of these objects before. In this chapter, you are going to be using the following properties and methods that are shown in Table 4.1. Table 4.1. DataAdapter, DataSet, DataTable, and DataRow Properties and Methods Object /Method Property Description DataAdapter Fill Fills DataSet and DataTable objects. CommandBuilde r GetUpdateComman d Creates an Update command and places it into the data adapter's UpdateCommand property. DataAdapter UpdateCommand Holds the SQL statement for the update. DataAdapter Close Closes the connection off the UpdateCommand. The syntax is dataadapter.UpdateCommand.Connect.Close() . DataAdapter Update Performs the update command against the dataset. DataSet Tables Represents a collection of tables found within a dataset. DataSet Rows Contains a collection of rows within a specified table in a dataset. DataSet AcceptChanges Sends the changes back to the server. DataRow ToString Retrieves the data from the column that is specified in the DataRow and returns it as a string value. DataRow BeginEdit Begins the editing of a DataRow, allowing you to replace values in the columns. DataRow EndEdit Completes the editing of a DataRow. You will see these objects with their properties and methods used in the following steps. Steps Open and run the VB.NET-Chapter 4 solution. From the main form, click on the command button with the caption How-To 4.1. When the form loads, click on the Load List button to display the customers that begin with the letter A. Click the Edit button. You will notice that the fields have now taken on a sunken look. Place the cursor into the City field and change the value to Dunkirk. Now click Save. If you move off the record and move back on, you will notice that the value has been saved. This form looks similar to the form created in Chapter 1. The difference is that this time you will not be using controls that are bound at design time. You can see the form in Figure 4.1. 1. Create a new Windows Form. 2.

Scialdone 1 and Sergio Ammendola 1,2 1 Centre of Biotechnology-Bioprogress, Anagni, Italy 2 AMBIOTEC SAS SS7, Cisterna di Latina, Italy Amide hydrolase (AH) and nitrilase (Nit) are two superfamilies of enzymes cleaving C–N bonds of differ- ent substrates [1]. These proteins all share the typical a ⁄ b hydrolase fold and can be grouped on the basis of their catalytic site and preferred substrate [2,3]. The enzymes of the Nit superfamily have a catalytic site formed by a Glu–Cys–Lys triad and can hydrolyse nitriles (EC 3.5.1.1) or the carboxylic amide group (EC 3.5.1.4) [4]. The AH superfamily includes the signature amidases, originally identified by primary structure analysis [5]. The substrate specificities and biological functions of these enzymes vary widely, but it has been shown that they all have a similar catalytic mechanism mediated by a Ser–cisSer–Lys catalytic triad [6–8]. Recently, the gene coding for the signature amidase from Sulfolobus solfataricus (SsAH) has been expressed in Escherichia coli and characterized [9]. This is a wide spectrum AH, converting carboxylic amides to their corresponding organic acids. We report that the SsAH enzyme also possesses nitrilase activity, a property shared by the well-characterized signature amidase from Rhodococcus rhodochrous J1 (RhorhJ1) [10,11]. Both enzymes contain an additional CX 3 C motif. To understand the structural basis of this dual spe- cificity, we constructed random mutants of SsAH and screened them for their activity on amide, nitrile and ester substrates. Mutants showing increased activity on nitriles all carried the Lys96Arg substitution, an obser- vation confirmed by site-directed mutagenesis. The structural framework of the observed mutations was investigated by constructing a homology model of the enzyme. The model suggests that a putative addi- tional catalytic triad formed by Ser171–Cys145–Lys96, where position 145 corresponds to the second cysteine of the additional CX 3 C motif, exists in this enzyme. We suggest that this alternative active site is respon- sible for the hydrolysis of nitriles, with Cys145 acting Keywords amidase; catalytic triad; CX 3 C; modelling; mutagenesis Correspondence S.

We report here that this enzyme also converts nitriles in the corresponding organic acid, simi- larly to the well characterized amidase from Rhodococcus rhodochrous J1. The archaeal and rhodococcal enzymes belong to the signature amidases and contain the typical serine-glycine rich motif. They work at different optimal temperature, share a high sequence similarity and both contain an additional CX 3 C motif. To explain their dual specificity, we built a 3D model of the structure of the S. solfataricus MEMORIES ARE MADE OF THIS Simon Aronson’s Introduction to Memorized Deck Magic Original Edition Copyright 1999 by Simon Aronson Revised Edition Copyright 2002 by Simon Aronson 2 • Simon Aronson’s The card conjurer’s repertory is never complete without employing the prearranged deck to some extent. - S.

Since that time much has happened to make the use of a memorized stack even more popular. Last year I published my book, Try the Impossible, which contains an in-depth exploration of the Aronson stack, plus two of the tricks that were contained in the original version of these notes. I also now have a website, at www.simonaronson.com, which allows me to share my ideas about magic generally, and about memorized deck magic in particular, on a more current basis over the internet. I’ve revised these notes in just a few minor respects, to update the references, correct any errors that have been brought to my attention, and in only a few places to clarify or expand on the ideas presented.] An awful lot has changed over the past twenty or so years. When I wrote my first book (The Card Ideas of Simon Aronson, 1978), I tipped my mitt on a lot of “underground” stuff that I had developed, using the memorized deck. In my introductory essay to that chapter, I mentioned that I sometimes felt “guiltily pleased” that so few of our advanced cardicians had (at that time) ever considered using the memorized deck. Well, I can’t feel such guilt any longer because the memorized deck has certainly come of age. Indeed, the past few years have seen a groundswell of interest in this venerable tool among some of the world’s most respected magical thinkers and performers. Lecturers at magic clubs around the country have showcased memorized deck miracles. But the enthusiasm is not limited just to the professionals. In magic chat rooms on the Internet, and at magic conventions, I am regularly besieged by eager, inventive amateurs who want to show me their latest twist or accomplishment with a memorized deck – and many are really good! The momentum is growing and contagious, and the sheer number of cardicians now using a memorized stack has produced a synergy that is causing the number of effects, tips, variations, and new principles to multiply exponentially. I’m happy to have been part of the inspiration for this renaissance, but there’s no reason to stop there. I’m constantly working on new memorized deck effects. So, it’s about time that you joined the ranks also. About This Introduction As the title implies, the purpose of this booklet is simply to introduce you to some of the basic principles and applications you need to know to get started with a memorized deck. In Section I, I define a few of the basic terms, and answer some of the more frequently asked questions about how to approach the topic. In Section II, I try to give you a sense of the power and scope of the memorized deck by discussing five principles that are commonly used in memorized deck applications. These principles are illustrated with several simple, though quite fooling, location effects. In Section III, I offer some thoughts on how one can best go about learning a memorized stack.

Over the last decade, a complex and ongoing series of conflicts, described as the world’s “deadliest crisis since World War II,” 1 unleashed unprecedented violence on the bodies of women and girls in this region. The brutality is extreme: “the raping of three-month-old infants and eighty-year-old women, the dispatching of militias who have HIV/AIDS and other sexually transmitted diseases to rape entire villages, women being held as sex slaves for weeks, months and years and women being forced to eat murdered babies.” 2 Women and girls are raped with such frequency that the Congolese invented a new word to describe the phenomenon: révioler, to re-rape. 3 For years, the international community has attempted to stop mass rape a GAO United States Government Accountability Office Report to Congressional Requesters September 2005 ELECTIONS Federal Efforts to Improve Security and Reliability of Electronic Voting Systems Are Under Way, but Key Activities Need to Be Completed GAO-05-956 What GAO Found United States Government Accountability Office Why GAO Did This Study Highlight s Accountability Integrity Reliability www.gao.gov/cgi-bin/getrpt?GAO-05-956.

Highlights of GAO-05-956, a report to congressional requesters September 2005 ELECTIONS Federal Efforts to Improve Security and Reliability of Electronic Voting Systems Are Under Way, but Key Activities Need to Be Completed While electronic voting systems hold promise for improving the election process, numerous entities have raised concerns about their security and reliability, citing instances of weak security controls, system design flaws, inadequate system version control, inadequate security testing, incorrect system configuration, poor security management, and vague or incomplete voting system standards (see below for examples). It is important to note that many of these concerns were based on specific system makes and models or a specific jurisdiction’s election, and there is no consensus among election officials and other experts on their pervasiveness. Nevertheless, some have caused problems in elections and therefore merit attention. Federal organizations and nongovernmental groups have issued both election-specific recommended practices for improving the voting process and more general guidance intended to help organizations manage information systems’ security and reliability. These recommended practices and guidelines (applicable throughout the voting system life cycle) include having vendors build security controls and audit trails into their systems during development, and having election officials specify security requirements when acquiring systems. Other suggested practices include testing and certifying systems against national voting system standards. The federal government has begun efforts intended to improve life cycle management of electronic voting systems and thereby improve their security and reliability. Specifically, EAC has led efforts to (1) draft changes to existing federal voluntary standards for voting systems, including provisions addressing security and reliability; (2) develop a process for certifying voting systems; (3) establish a program to accredit independent laboratories to test electronic voting systems; and (4) develop a library and clearinghouse for information on state and local elections and systems. However, these actions are unlikely to have a significant effect in the 2006 federal election cycle because important changes to the voting standards have not yet been completed, the system certification and laboratory accreditation programs are still in development, and a system software library has not been updated or improved since the 2004 election. Further, EAC has not consistently defined specific tasks, processes, and time frames for completing these activities; as a .. .Miracles Are Made To Be Shared The wind picked up, causing the images below to gradually lose their separate identity and meld together Paul simultaneously felt himself merging into the... well, Paul; you’ve written a lovely story, one that will be read for a long time to come.” Paul shook his head “I didn’t write any stories, Rafe, though I may have told a tale or two Sandra is the... scene below and being pulled upward “It’s a beautiful evening for flying, isn’t it?” Rafe looked exactly as he had on that day nearly fifty years ago when he had plucked Paul from the air below
