Chuyển đổi tài liệu PDF sang Word 01:07' 22/11/2005 (GMT+7) Word đã trở thành "vua" của các bộ soạn thảo văn bản. Hầu hết các văn bản đều được định dạng và in bằng Word. Tuy nhiên, bạn có một số văn bản bằng PDF (Portable Document Format), bạn muốn chỉnh sửa các tài liệu này trước khi in ấn. Acrobat Reader không có khả năng chỉnh sửa văn bản, còn Acrobat thì giá cả hơi "mắc" mà lại đòi hỏi tài nguyên khá lớn. Vậy, có phần mềm nào có khả năng chuyển đổi định dạng từ PDF sang Word mà vẫn giữ nguyên định dạng, giá cả cũng chấp nhận được và lại tiêu tốn ít tài nguyên hệ thống ? Thực ra, để giữ nguyên các định dạng tài liệu sau khi chuyển đổi là rất phức tạp và khó khăn. Đến ngay như phần mềm Acrobat, khi chuyển đổi tập tin PDF sang Word cũng không được hoàn hảo. Tuy nhiên, nếu bạn đã từng sử dụng qua phần mềm SolidPDFConverter của hãng Solid, phần mềm này thật tuyệt vời ! Các tài liệu phức tạp gồm các nội dung văn bản, hình ảnh, bảng tính . vẫn giữ nguyên định dạng sau khi chuyển đổi sang Word. VietNamNet đã thử nghiệm chuyển đổi tài liệu phức tạp gồm hình ảnh, bảng biểu , đồ hoạ, văn bản xen kẽ, khoảng 70 trang bằng Adobe Acrobat và SolidDPFConverter. Kết quả là SolidPDFConverter cho tốc độ chuyển đổi tài liệu nhanh hơn và giữ được định dạng tài liệu gốc chính xác hơn Acrobat. Tuy nhiên khi chỉnh sửa một số văn bản kết hợp trong các bảng biểu, đồ hoạ cho kết quả chưa được tốt lắm. Mặc dù vậy SolidPDFConverter vẫn là công cụ đáng giá với mức giá tương đối rẻ so với phần mềm đồ sộ tương đối "nặng ký" Acrobat. SolidPDFConverter có đồ thuật đơn giản sẽ giúp bạn chuyển đổi định dạng .pdf sang định dạng .doc nhanh chóng chỉ với 5 bước: Bước 1: Chọn định dạng Bạn hãy chọn tập tin PDF cần chuyển đổi ngay trong khung tìm tài liệu của SolidPDFConverter. Hãy sử dụng tùy chọn: • Flowing: Với chế độ này, các trang vẫn giữ nguyên cách trình bày, định dạng, đồ họa và các dữ liệu văn bản. • Continuous: Với chế độ này cái mà bạn cần chỉ là nội dung chứ không cần chính xác cách trình bày của tài liệu. Ví dụ: giả sử mục đích là bạn cần nội dung cho những trang có kích thước khác hoặc các phần mềm trình diễn như Power Point hoặc chuyển sang định dạng HTML. Chế độ này sẽ sử dụng cách phân tích trình bày trang và cột để xây dựng lại thứ tự các văn bản nhưng chỉ phục hồi định dạng đoạn, đồ họa, và dữ liệu văn bản. • Plain Text: Nếu bạn chỉ cần văn bản mà không cần định dạng hay trình bày, bạn hãy sử dụng Plain Text. Plain Text sẽ phục hồi các định dạng kí tự, đoạn hoặc đồ họa nhưng chỉ phục hồi văn bản bằng phân tích cột và trình bày trang. • Exact: Nếu bạn cần một tài liệu Word trông giống hệt như tài liệu PDF? Bạn cần thay đổi nhỏ các tập tin này? Exact sử dụng các TextBox của Word để đảm bảo chắc chắn văn bản và đồ họa vẫn giống y nguyên bản PDF gốc.Chế độ Exact không nên sử dụng nếu bạn cần chỉnh sửa rất nhiều nội dung từ Active Transport Active Transport Bởi: OpenStaxCollege Active transport mechanisms require the use of the cell’s energy, usually in the form of adenosine triphosphate (ATP) If a substance must move into the cell against its concentration gradient—that is, if the concentration of the substance inside the cell is greater than its concentration in the extracellular fluid (and vice versa)—the cell must use energy to move the substance Some active transport mechanisms move smallmolecular weight materials, such as ions, through the membrane Other mechanisms transport much larger molecules Electrochemical Gradient We have discussed simple concentration gradients—differential concentrations of a substance across a space or a membrane—but in living systems, gradients are more complex Because ions move into and out of cells and because cells contain proteins that not move across the membrane and are mostly negatively charged, there is also an electrical gradient, a difference of charge, across the plasma membrane The interior of living cells is electrically negative with respect to the extracellular fluid in which they are bathed, and at the same time, cells have higher concentrations of potassium (K+) and lower concentrations of sodium (Na+) than does the extracellular fluid So in a living cell, the concentration gradient of Na+ tends to drive it into the cell, and the electrical gradient of Na+ (a positive ion) also tends to drive it inward to the negatively charged interior The situation is more complex, however, for other elements such as potassium The electrical gradient of K+, a positive ion, also tends to drive it into the cell, but the concentration gradient of K+ tends to drive K+ out of the cell ([link]) The combined gradient of concentration and electrical charge that affects an ion is called its electrochemical gradient Art Connection 1/8 Active Transport Electrochemical gradients arise from the combined effects of concentration gradients and electrical gradients (credit: “Synaptitude”/Wikimedia Commons) Injection of a potassium solution into a person’s blood is lethal; this is used in capital punishment and euthanasia Why you think a potassium solution injection is lethal? Moving Against a Gradient To move substances against a concentration or electrochemical gradient, the cell must use energy This energy is harvested from ATP generated through the cell’s metabolism Active transport mechanisms, collectively called pumps, work against electrochemical gradients Small substances constantly pass through plasma membranes Active transport maintains concentrations of ions and other substances needed by living cells in the face of these passive movements Much of a cell’s supply of metabolic energy may be spent maintaining these processes (Most of a red blood cell’s metabolic energy is used to maintain the imbalance between exterior and interior sodium and potassium levels required by the cell.) Because active transport mechanisms depend on a cell’s metabolism for energy, they are sensitive to many metabolic poisons that interfere with the supply of ATP Two mechanisms exist for the transport of small-molecular weight material and small molecules Primary active transport moves ions across a membrane and creates a difference in charge across that membrane, which is directly dependent on ATP 2/8 Active Transport Secondary active transport describes the movement of material that is due to the electrochemical gradient established by primary active transport that does not directly require ATP Carrier Proteins for Active Transport An important membrane adaption for active transport is the presence of specific carrier proteins or pumps to facilitate movement: there are three types of these proteins or transporters ([link]) A uniporter carries one specific ion or molecule A symporter carries two different ions or molecules, both in the same direction An antiporter also carries two different ions or molecules, but in different directions All of these transporters can also transport small, uncharged organic molecules like glucose These three types of carrier proteins are also found in facilitated diffusion, but they not require ATP to work in that process Some examples of pumps for active transport are Na+-K+ ATPase, which carries sodium and potassium ions, and H+-K+ ATPase, which carries hydrogen and potassium ions Both of these are antiporter carrier proteins Two other carrier proteins are Ca2+ ATPase and H+ ATPase, which carry only calcium and only hydrogen ions, respectively Both are pumps A uniporter carries one molecule or ion A symporter carries two different molecules or ions, both in the same direction An antiporter also carries two different molecules or ions, but in different directions (credit: modification of work by “Lupask”/Wikimedia Commons) Primary Active Transport The primary active transport that functions with the active transport of sodium and potassium allows secondary active transport to occur The ...

Microsoft, a new member of the directory service club, has created a directory service on which almost its entire product line depends. Understanding Active Directory is thus a prerequisite to any management or deployment of Windows 2000. In the 1970s, all the computing resources you needed, or could use, were on the same computer or the terminal you logged on at. In the 1980s, with the advent of the PC LAN, many files were located on remote machines, and there were definitive paths to these machines. LAN users shared the files and printers, and exchanged e-mail on the LAN. Before the end of the 1990s, we witnessed the beginning of the paradigm shift where all information and functionality could be accessed on any server on any network anywhere . . . and the user did not need to know where the objects were physically located. This is the ideal computing model in which all network objects — servers, devices, functionality, information, authen- tication, and the transports — combine to become a single contiguous information system and computing environment. This environ-ment allows users, whether human or machine, to attach — or remain attached—to systems from a consis- tent user interface at any point of entry on the network. No matter what users require — be they functions of a device, communication, process, algorithms, or perhaps just infor- mation and knowledge — they must be able to access such an object without regard for its physical location. The Active Directory is Microsoft’s bold leap to realizing the dream of a truly distributed environment and IS architecture. It has been talked about for many years. Headlines in the technical trades were always gloomy. And thus, many network administrators and systems engineers forgot about the 2 2 CHAPTER ✦✦✦✦ In This Chapter The Origins of Active Directory The Elements of Active Directory Comparing Windows NT and Windows 2000 domains ✦✦✦✦ 4667-8 ch02.f.qc 5/15/00 1:56 PM Page 25 26 Part I ✦ Windows 2000 Server Architecture directory and worked hard to refine or improve what was already in place, at considerable investment. But now the directory is here. And you probably have little idea what it is and how to use it. You should not feel ashamed, because not only are you not alone, but also it is unlike anything you have ever used before. Every day people ask us about the Active Directory (and these are not only Windows NT or UNIX and NetWare professionals, but also mid-range and mainframe engineers). The purpose of this chapter is to drill down to its core, to expose the elements, and to lay the foundations to bring what’s precious to the surface, and then move for- ward. First, you must understand everything about the Active Directory (AD) before you can make the transition from the old ways of managing networks and computing environments to the promise that waits. In this chapter, we discuss the elements of AD. We will kick off with a brief discussion of how and why we will use AD, and from whence it came. Then we break it down into its constituent components (its logical structure), and finally we discuss how the components work and interoperate with each other. You will notice that the subject of Windows domains and trusts is going to be left until a full discussion of the AD has been achieved. This chapter also features the first appearance of Millennium City, or mcity.org , which is the example Windows 2000 network infrastructure we use throughout the book. It’s a network that runs the infrastructure of an entire city, and its Active Directory is what we used to test the limits of what Microsoft says it’s capable of. MCITY is essentially one huge Active Directory laboratory. You don’t This document and trademark(s) contained herein are protected by law as indicated in a notice appearing later in this work.
