For lighter than air gases, the hazard radius shall be 5 m.
Hence it is acceptable to use air drawn from a Zone 2 area. With a Contractor involved, the initial work will normally be carried out by the Contractor, preferably with BP involvement as the classification is developed. Up15 are valves in molecular sieve or pressure swing adsorption processes.
Ventilation shall therefore be provided for non-sealed types so that hydrogen concentrations are kept below 0. Where fluids in more than one category are present, then the most volatile of the fluids present shall be used as the basis for estimating the extent of the Hazardous Area, i.
The ventilation system shall be designed to avoid stagnant areas where a hydrocarbon-rich atmosphere could collect. Each case should be considered individually. Note that lighter than air gases are often confined to a small section of the plant. Any exception to this shall be subject to approval by BP. I thought it was a free document. Commentary provides background information which supports the requirements of the Recommended Practice, and may discuss alternative options.

Weiss and Hess  reviewed the literature and found that the strategies and concepts for providing regional anaesthesia during labour and delivery in anticoagulated patients cardiopatia no cianotica controversial, and also mentioned that lumbar anaesthesia contributes to the risk of spinal haematoma in dongenita receiving antithrombotic drugs.
To avoid this, we opted for general anaesthesia. This may be achieved by combining a short-acting i. Although ketamine has wcianotica advantages over barbiturates as an induction agent, in that it does not reduce SVR but causes increase in the heart rate,  which is undesirable.
Traditional and contemporary teaching considers all obstetric patients to be at increased risk for pulmonary aspiration compared with patients scheduled for non-obstetric elective surgical procedures, mandating antacid prophylaxis as well as rapid sequence induction cardiopatia no cianotica cricoid pressure.
However, the requirements of a patient at risk for aspiration are difficult to reconcile with a judicious, titrated induction of anaesthesia that is ideal for a patient with severely compromised cardiac function.
The problems of general anaesthesia and positive-pressure ventilation are decrease in venous return and cardiac output. Hence, we decided to maintain ciwnotica Cardiopatia no cianotica with prophylactic dopamine infusion titrating to the effect.
We avoided nitrous oxide because it is a potent pulmonary vasoconstrictor. Cole and colleagues  stated that the policy of using uterine cardiopatia no cianotica followed by a slow oxytocin infusion proved safe and effective in these patients. Oxytocin as a bolus causes direct vasodilation and reduces SVR with compensatory increase in the heart rate and cardiac output.

There is No Software. Friedrich Kittler. Grammatologies of the present time have to start with a rather sad statement. The bulk of written texts – including this text. The following 3 pages link to this file: Friedrich Kittler · Software studies · File: Kittler Friedrich There is no (file redirect). A few years ago, the literary and media historian Friedrich Kittler opened an essay called “There Is No Software” with a “rather sad statement.” In his view, “the .
Friedrich Kittler Grammatologies of the present time have to start with a rather sad statement. The bulk of written texts – including this text – do not exist anymore in perceivable time and space but in a computer memory’s kittlet cells. And since these cells in the last three decades have shrunk to spatial extensions below one micrometer, our writing may well be defined by a self-similarity of letters over some six decades.
This state of affairs makes not only a difference to history when, at its alphabetical beginning, a camel and its Hebraic letter kittleg were just 2. This crazy kind of software engineering suffered from an incurable confusion between use and mention. Up to Holderlin’s time, a mere mention of lightning seemed to have been sufficient evidence of its possible poetic use. After this lightning’s metamorphosis into electricity, human-made writing passes through microscopically written inscriptions which, in contrast to all historical writing tools, are able to read and write by themselves.
The last historical act of writing may well have been the moment when, in the early seventies, Intel engineers laid out some dozen square meters of blueprint paper 64 square meters, in the case of the later in order to design the hardware architecture of their first integrated microprocessor. This manual layout of two thousand transistors and their interconnections was then miniaturized to the size of an actual chip, and, by electro-optical machines, written softqare silicon layers.
Finally, this microprocessor found its place in the new desk calculators of Intel’s Japanese customer 1 and our postmodern writing scene began.
For the hardware complexity of such microprocessors tere discards manual design techniques; in order to lay out the next computer generation, the engineers, instead of filling out uncountable meters of blueprint paper, have recourse to Computer Aided Design, that is, to the geometrical or autorouting powers of the actual generation. However, in constructing the first integrated microprocessor, Intel’s Marcian E. Hoff had given an almost perfect demonstration of a Turing machine.
Sincecomputing, whether done by people or by machines, has been formalized as a countable set of instructions operating on an infinitely long paper band and its discrete signs. Turing’s concept of such a paper machine 2 whose operations consist only of writing and reading, proceeding and receding, has proven to be the mathematical equivalent of any computable function. Universal Turing machines, when fed with the instructions of any other machine, can effectively imitate it.
Thus, precisely because eventual differences between hardware implementations do not count anymore, the so-called Church-Turing hypothesis in its strongest or physical form is tantamount to declaring nature itself a universal Turing machine. This eoftware, in itself, has had the effect of duplicating the implosion of hardware by an explosion of software. Programming languages have eroded the monopoly of ordinary language and grown into a ,ittler hierarchy of their kittlee.
This postmodern tower of Babel reaches from simple operation codes whose linguistic extension is still a hardware configuration passing through an assembler whose extension is that very assembler. As a consequence, far reaching chains of self-similarities in the sense defined by fractal theory organize the software as well as the hardware of every writing.
What remains a problem is only the realization of these layers which, just as modern media technologies in general, have been explicitly contrived in order to evade all perception.
There is No Software
We simply do not know what our writing does. For an illustration of this problem, a simple text program like the one that has produced my very paper will do. In order to wordprocess a text and, that is, to become yourself a paper machine working on an IBM AT under Microsoft DOS, you need first of all to buy fridrich commercial kjttler.
Unless these have the file extension of. The reason is that only. EXE files entertain a strange relation to their proper name. At the one hand, they bear grandiloquent names such as Kitrler, on the other hand, they bear a more or less cryptic because non-vocalized acronym such as WP. The full name, alas, serves only the advertising strategies of software manufacturers, since DOS as a microprocessor operating system could never read file names longer than eight letters.
Friedrich Kittler (1995), There is No Software
That is why the unpronounceable acronym WP, this posthistoric revocation of a fundamental Greek innovation, is not only necessary, but amply sufficient for postmodern wordprocessing. In fact, it seems to bring back truly magical power; WP does what it says. Executable computer files encompass, by contrast not only to “WordPerfect” but also to the big, empty old European words such as “Mind” or “Word”, all the old routines and data necessary to their self-constitution.
Surely, tapping the letter sequence of “W”, “P” and “enter” on an AT keyboard does not make the Word perfect, but this simple writing act starts the actual execution of WordPerfect. Such are the triumphs of software. The accompanying paperware cannot but multiply these magical powers, written as they are in order to bridge the gap between formal and everyday languages.
Electronics as literature; the linguistic agent ruling with near omnipotence over the computer system’s resources, address spaces, and other hardware parameters: WP, when called with command line argument X, would change the monitor screen from color A to B, start in mode C, return finally to D, et cetera ad infinitum. In fact, however, these actions of agent WP are virtual ones, since each of them has to run under DOS.
It is the operating system and, more precisely, its command shell that scans the keyboard for eight bit file names on the input line, transforms some relative addresses of an eventually retrieved file into absolute ones, loads this new version from external mass memory to the necessary random access space, and finally or temporarily passes execution to the op code lines of a slave named WordPerfect. The same argument would hold against DOS which, in the final analysis, resolves into an extension of the basic input and output system called BIOS.
Not only no program, but no underlying microprocessor system could ever start without the rather incredible autobooting faculty of some elementary functions that, for safety’s sake, are burned into silicon and thus form part of the hardware.
Any transformation of matter from entropy to information, from a million sleeping transistors into differences between electronic potentials, necessarily presupposes a material event called “reset”. In principle, this kind of descent from software to hardware, from higher to lower levels of observation, could be continued over more and more decades.
All code operations, despite their metaphoric faculties such as “call” or “return”, come down to absolutely local string manipulations and that is, I am afraid, to signifiers of voltage differences. Formalization in Hilbert’s sense does away with theory itself, insofar as “the theory is no longer a system of meaningful propositions, but one of sentences as sequences of words, which are in turn sequences of letters.
We can tell [say] by reference to the form alone which combinations of the words are sentences, which sentences are axioms, and which sentences follow as immediate consequences of others.
Rather, there would be no software if computer systems were not surrounded any longer by an environment of everyday languages. This environment, however, since a famous and twofold Greek invention, consists of letters and coins, of books and bucks.
In all philanthropic sincerity, high-level programming manuals caution against the psychopathological risks of writing assembler code. Firstly, on an intentionally superficial level, perfect graphic user interfaces, since they dispense with writing itself, hide a whole machine from its users. Instead, the physical Church-Turing hypothesis, by identifying physical hardware with the algorithm forged for its computation has finally got rid of hardware itself. As an effect, software successfully occupied the empty place and profited from its obscurity.
The ever-growing hierarchy of high-level programming languages works exactly the same way as one-way functions in recent mathematical cryptography. These kinds of functions, when used in their straightforward form, can be computed in reasonable time, in a time growing only in polynomial expressions with the function’s complexity. The time needed for its inverse form, however; that is for reconstructing from the functions’ output its presupposed input; would grow at an exponential and therefore unviable rates.
One-way functions, in other words, hide an algorithm from its very result. For software, this cryptographic effect offers a convenient way to bypass the fact that by virtue of Turing’s proof the softwware of mental property as applied to algorithms has become meaningless.
Precisely because software does not exist as a ie faculty, software as a commercial or American medium insists all the more. Every license, every dongle, every trademark registered for WP as well as for WordPerfect prove the functionality of one-way functions.
In the USA, notwithstanding all mathematical tradition, even a copyright claim for algorithms has recently succeeded. At most, finally, there has been, on ks part of IBM, research on a mathematical formula that would enable them to measure the distance in complexity between an algorithm and its output.
Whereas in the good old days of Shannon’s mathematical theory of information, the maximum of information coincided strangely with maximal unpredictability or noise, 9 the new IBM measure, called logical depth, has been defined as follows: The value of a message [ In other words, the value of a message is the amount of mathematical or other work plausibly done by its originator, which friedricch receiver is saved from having to repeat.
Thus logical depth, in its mathematical rigor, could advantageously replace all the old everyday language definitions of originality, authorship and copyright in their necessary inexactness, were it not for the fact that precisely this algorithm intended to compute the cost of algorithms in general is Turing-uncomputable itself. The high court’s reasoning, according to kittlrr without the correspondent electrical charges in silicon circuitry no computer program would ever run 12can already illustrate the fact that the virtual undecidability between software and hardware xoftware by no means, as system theorists would probably like to believe, from a simple variation of observation points.
Friedrich Kittler (), There is No Software – Hui Yie’s Thinking Blog
On the contrary, there are good grounds to assume the indispensability and, consequently, the priority of hardware in general. Only in Turing’s paper On Computable Numbers With An Application to the Entscheidungsproblem there existed a machine with unbounded resources in space and time, with infinite supply of raw paper and no constraints on computation speed.
All physically feasible machines, in contrast, are limited by these parameters in their very code. The inability of Microsoft DOS to tell more than the first eight letters of a file name such as WordPerfect gives just a trivial or obsolete illustration of a problem that has provoked not softdare the ever-growing incompatibilities between the different generations of eight-bit, sixteen-bit and thirty-two-bit microprocessors, but also a near impossibility of digitizing the body of real numbers 13 formerly known as nature.
We must reduce a continuous algorithmic description to one codable on a device whose fundamental operations are countable, and we do this rriedrich various forms of chopping into pieces, usually called discretization. The outcome is a discrete and synthetic microworld image skftware the original problem, whose structure is arbitrarily fixed by a differencing scheme and computational architecture chosen at random.
This is what we actually do when we compute up a model of the physical world with physical devices. Thus, instead of pursuing the physical Church-Turing-hypothesis, that is of “injecting an algorithmic behavior into the behavior of the physical world for which friedruch is no evidence,” 15 one has rather to compute what has been called “the prize of programmability” itself. This all-important property of being programmable has, in all evidence, nothing to do with software; it is an exclusive feature of hardware, more or less suited as it is to house some notation system.
When Claude Shannon, inproved in what is probably the froedrich consequential MA thesis ever written 16 that simple telegraph switching relays can implement by means of their different interconnections the whole of Boolean algebra, such a physical notation system was established. And when the integrated circuit, developed in the s out of Shockley’s transistor, combined on one chip silicon as a controllable resistor with its own oxide as an almost perfect isolator, the programmability of matter could finally “take control” just as Turing had predicted.
For, in their combination on chip, silicon and its oxide provide for perfect hardware architectures. That is to say that the millions of basic elements work under almost the same physical conditions, especially as regards the most critical, namely temperature dependent degradations, and yet, electrically, all of them are highly isolated from each other.
Only this paradoxical relation between two physical parameters, thermal continuity and electrical discretization on chip, allows integrated circuits to be not only finite state machines like so many other devices on earth, but to approximate that Universal Discrete Machine into which its inventor’s name has long disappeared.
This structural difference can be easily illustrated.
As a consequence it is not structurally programmable, and in this case it is effectively programmable only in the limited sense that its state can be set for achieving a limited class of behaviours. Confronted as they are with a continuous environment of weather, waves, and wars, digital computers can cope with this real number-avalanche only by adding element to element. However, the growth rate of possible interconnections between those elements and, that is, of computing power as such, is proven to have a square root function as its upper bound.
In other words, it cannot even “keep up with polynomial growth rates in problem size. That is why these systems show polynomial growth rates in complexity and, consequently, why only computations done on nonprogrammable machines could keep up with them. In all evidence, this hypothetical but all too necessary type of machine would constitute sheer hardware, a physical device working amidst physical devices and subjected to the same bounded resources.
Software in the usual sense of an ever-feasible abstraction would not exist any more.
The procedures of these machines, though still open to friedrch algorithmic notation, would have to work essentially on a material substrate whose very connectivity would allow for cellular reconfigurations. And even though the “substrate can also be described in algorithmic terms, by means of simulation,” its ” Silicon hardware obeys many of the requisites for such highly connected, non-programmable systems.
Between its millions of transistor cells, some million to the power of two interactions take place already; there is electronic diffusion, there is quantum mechanical tunneling all over the chip. Freidrich minimize all the noise that it would be possible to eliminate is the prize paid for structurally programmable machines.
The inverse strategy of maximizing noise would not only find the way back from IBM to Shannon, it may well be the only way to enter that body of real numbers originally known as chaos. Archiv fur Misikwissenschaft,p. Andrew Hodges, Alan Turing: The EnigmaNew Yorkp. Hans-Ulrich Gumbrecht and K.

By using aria-describedby to reference the format of the field, this information is made available to the users on request. Other screen readers will formhet at the label, and in this example will probably guess accurately.
Screen readers will announce both the label and help text when the form field has focus. However, fkrm additional help text is available, it can be associated with the form field using the aria-describedby attribute. Placeholder text is usually displayed with lower color contrast than text provided by users, and it disappears from form fields when users start entering text. For example, indicate any required and optional input, allowed data formats, and timing limitations.
Be aware that this makes it very hard for users to review the form. University of Washington Be boundless Connect with us: Provide instructions to dormnet users understand how to complete the form and use individual form controls. To ensure backward compatibility, the for and id attributes are also used formmnet this example.
While placeholder text provides valuable guidance for many users, placeholder text is not a replacement for labels. This page combined the following WCAG 2. Overall instructions Where relevant, provide overall instructions that apply to the entire form.
Information, structure, and relationships conveyed through presentation can be programmatically determined accessibld are available in text. Providing instructions outside of labels allows more flexible positioning and design, but sometimes it can be missed. At the time of writing this tutorial, this approach is not fully supported by all web browsers and assistive technologies, for example, Braille displays.
It is critical to include form instructions in ways that can be read aloud. In the example below, form instructions indicate how required fields are marked, the expected format for the main data fields, and where to find additional help for each input.
Section Hidden labels of accessbile tutorial describes how to hide information visually but keep it available to assistive technology.
Creating Accessible Forms
This makes sense if the user has been informed of the format before, or when there are lots of input fields with the same format, for example. For groups of related fields such as radio buttons and checkboxes, each form field must have a label as described in the previous section. Jump to the navigation Provide instructions to help users understand how to complete the form and use individual form controls.
In most web browsers the color of the placeholder can be styled using proprietary CSS selectors. At the time of writing this tutorial, web browsers usually display the placeholder text in a color that does not meet the minimum contrast requirement of WCAG 2. Labels or instructions are provided when content requires user input. To create an accessible online form, you must ensure that all form fields have accurate labels or prompts so screen reader users know what each field is asking for.
Placeholder text provides instructions or an example of the required data format inside form fields that have not yet been edited by the user. For example, to indicate required input fields and data formats in the text of the labels. Interactive forms in Adobe PDF have many of the same issues as those described above. In addition to overall instructions, it is also important to provide relevant instructions within the labels of the form controls.
If the placeholder text contains instructional information or examples that disappear, it makes it more difficult for users to check their responses before submitting the form. Labels and prompts must all be created in a way that explicitly associates them with their corresponding form fields. That is, it is not automatically displayed or read aloud.

Ensuring that a contrast ratio of at least 4. Following are a few techniques for accomplishing this. Web browsers use a combination of color and accessiblr to achieve this effect.
For simple use cases, providing instructions within labels may be sufficient. This same approach can be used to avoid visual redundancy of displaying both labels and placeholder text. These tutorials provide best-practice guidance on implementing accessibility in different situations. For all user interface components including but not limited to:
