First, the progressive increase in our understanding of the molecular genetic basis of VWD has resulted in rational applications of molecular testing to complement the current range of phenotypic tests for VWD. These molecular genetic strategies are most effectively directed at the prenatal diagnosis of type 3 VWD and confirmatory testing for types 2B and 2N disease.
In contrast, the use of molecular testing to clarify the diagnosis of type 1 VWD is of marginal benefit, at best. In terms of VWD therapies, a new recombinant VWF concentrate has recently completed successful clinical trials and is now awaiting more widespread application. There have even been some pre-clinical successes with VWF gene transfer although the clinical rationale for this therapeutic strategy needs careful consideration.
Much more remains to be learnt about the biology of VWF and further translational advances for the enhancement of VWD care will inevitably be realized.

Hydrological tracer techniques are a means of making statements on the direction and speed of underground water. One of the simpler tasks is to find out whether there is hydrological communication between two given points. This requires a determination of the direction of flow, which places less exacting demands on the properties of the tracer than does the task of determining the flow velocity of underground water.
Tracer methods can serve to infer from flow velocity the distance flow velocity, which is defined as the ratio between the distance between two points located in flow direction and the actual time it takes water to flow from one to the other. Der einfachere Fall liegt vor, wenn festgestellt werden soll, ob zwischen zwei Punkten eine hydrologische Verbindung besteht. Bei dieser Fliessrichtungsbestimmung sind die Forderungen an die Eigenschaften der einzusetzenden Tracer geringer als bei der Bestimmung der Geschwindigkeit des unterirdischen Wassers.

Ludwig Leichhardt und Alexander von Humboldt. Es wird das einzige Treffen der beiden Naturwissenschaftler bleiben. Abstract During July a meeting between two men takes place, which seems to have been extraneous, but turns out to be a significant historical incident. The prospective young scientist expects help and references from famous Alexander von Humboldt. Unfortunately this is going to be the only meeting between the two scientists even though the two Prussians have more in common than their passion for the natural sciences.

Clarifying the link between von Neumann and thermodynamic entropies. A Shenker's paper initiated a debate about its link with the entropy of phenomenological thermodynamics. Referring to Gibbs's and von Neumann's founding texts, we replace von Neumann's contribution in its historical context, after Gibbs's treatise and before the creation of the information entropy concept, which places boundaries into the debate.
Reexamining von Neumann's reasoning, we stress that the part of his reasoning implied in the debate mainly uses thermodynamics, not quantum mechanics, and identify two implicit postulates. We thoroughly examine Shenker's and ensuing papers, insisting upon the presence of open thermodynamical subsystems, imposing us the use of the chemical potential concept. We briefly mention Landau's approach to the quantum entropy. On the whole, it is shown that von Neumann's viewpoint is right, and why Shenker's claim that von Neumann entropy "is not the quantum-mechanical correlate of thermodynamic entropy" can't be retained.
Glukokortikoide sind auch in vivo imstande, die OPG-Serumspiegel deutlich zu reduzieren. It is almost sixty years since Emil Fischer was describing on a platform such as this one some of the work which led to the basic knowledge of the structure of glucose and its relatives. Today we will be concerned with a description of the experiments which have led to a knowledge of the principal reactions by which those carbohydrate structures are created by photosynthetic organisms from carbon dioxide and water, using the energy of light.
The speculations on the way in which carbohydrate was built from carbon dioxide began not long after the recognition of the basic reaction and were carried forward first by Justus von Liebig and then by Adolf von Baeyer and, finally, by Richard Wilstatter and Arthur Stoll into this century. Actually, the route by which animal organisms performed the reverse reaction, that is, the combustion of carbohydrate to carbon dioxide and water with the utilization of the energy resulting from this combination, turned out to be the first one to be successfully mapped, primarily by Otto Meyerhoi and Hans Krebs.
Our own interest in the basic process of solar energy conversion by green plants began some time in the years between and , during my postdoctoral studies with Professor Michael Polanyi at Manchester.

It was there I first became conscious of the remarkable properties of coordinated metal compounds, particularly metalloporphyins as represented by heme and chlorophyll. A study was begun at that time, which is still continuing, on the electronic behavior of such metalloporphyrins. It was extended and generalized by the stimulus of Professor Gilbert N. Lewis upon my arrival in Berkeley.
I hope these continuing studies may one day contribute to the understanding of the precise way in which chlorophyll and its relatives accomplish the primary quantum conversion into chemical potential which is used to drive the carbohydrate synthesis reaction.

When redeveloping buildings it is common to use window constructions with air-tight rabbets which obviate the inflow of fresh air almost entirely. This leads to the well-known structural-physics and hygienic consequences.
As an added effect, the distinctly enhanced thermal insulation results in changes in dynamic heat loss. The paper focuses on the issues of how to safeguard the inflow of fresh air, and the heating capacity of radiators.

We study Jauch-Piron states and two-valued measures on von Neumann algebra. Moreover, we show that this result holds for type I factor indenpendently on the set-theoretical axiomatics.
As a consequence we obtain a lucid characterization of pure Jauch-Piron states on von Neumann algebras acting on a Hilbert space with real-nonmeasurable dimension this can be viewed as a generalization of the paper. We also characterize the von Neumann algebras whose logic of projections is Jauch-Piron.
Finally, we prove that every two-valued measure on the projection logic of A, where A contains no type I 2 central portion, has to be concentrated at an abelian direct summand of A.

According to what has become a standard history of quantum mechanics, in von Neumann persuaded the physics community that hidden variables are impossible as a matter of principle, after which leading proponents of the Copenhagen interpretation put the situation to good use by arguing that the completeness of quantum mechanics was undeniable.
This state of affairs lasted, so the story continues, until Bell in exposed von Neumann's proof as obviously wrong. The realization that von Neumann's proof was fallacious then rehabilitated hidden variables and made serious foundational research possible again. It is often added in recent accounts that von Neumann's error had been spotted almost immediately by Grete Hermann, but that her discovery was of no effect due to the dominant Copenhagen Zeitgeist. We shall attempt to tell a story that is more historically accurate and less ideologically charged. Most importantly, von Neumann never claimed to have shown the impossibility of hidden variables tout court, but argued that hidden-variable theories must possess a structure that deviates fundamentally from that of quantum mechanics.
Both Hermann and Bell appear to have missed this point; moreover, both raised unjustified technical objections to the proof. Von Neumann's argument was basically that hidden-variables schemes must violate the ;quantum principle; that physical quantities are to be represented by operators in a Hilbert space.
As a consequence, hidden-variables schemes, though possible in principle, necessarily exhibit a certain kind of contextuality. As we shall illustrate, early reactions to Bohm's theory are in agreement with this account. Leading physicists pointed out that Bohm's theory has the strange feature that pre-existing particle properties do not generally reveal themselves in measurements, in accordance with von Neumann's result.
They did not conclude that the ;impossible was done; and that von Neumann had been shown wrong.

Its technical realisation and development to market maturity took no more than 5 years. In the first process stage the waste is converted to high-carbon pyrolysis charcoal and high-rank gas in the absence of oxygen. In the second stage these substances are oxidised by addition of oxygen.
The resulting temperature causes the non-combustible constituents of the slag to melt. In a third, optional, stage this molten slag can be liberated of heavy metals to such an extent that it can subsequently be used directly as additive for grinding. Further exhaust gas treatment is facilitated by the use of a circulatory fluidised-bed secondary combustion chamber.

Full Text Available Article in GermanAbstract in English and GermanAlexander von Humboldt and his correspondents liked to enrich or embellish their letters with quotations from classic works of ancient literature as well as from recent poems, plays, or novels. This paper tries to show that references to literature were very often used in order to express thoughts and feelings more clearly not so much for impressing the recipients of letters with high education.
In educated circles a good knowledge of ancient and modern works of literature was a standard requirement, which often allowed the letter writers to use quotations in a playful manner. Richard von Volkmann , one of the most important surgeons of the 19 th century, is regarded as one of the fathers of orthopaedic surgery. This led him to introduce the "antiseptic technique" to Germany that was developed by Lister.
Volkmann's contracture and the Hueter-Volkmann law. Additionally, he was a gifted writer; he published not only scientific literature but also books of children's fairy tales and poems under the pen name of Richard Leander, assuring him a permanent place in the world of literature as well as orthopaedics. Geschichte der Natur bei Alexander von Humboldt. This article analyses the importance of an historical view of nature in the works of Alexander von Humboldt. In several of his first writings, Humboldt seems to outline the importance of what one may call history of nature.
But even before his famous American travel, his position changed and he became reluctant to accept the seriousness of historical enquiry in the area of natural sciences: Humboldt kept his sceptical attitude in the first decades of the 19th century, despite the positive results of the palaeontological researches of his scientific colleagues. However, he gradually convinced himself of the scientific interest of historical investigations in the natural sciences. The Cosmos paradoxally displays two apparently conflicting points of view: Hypercontractivity in group Von Neumann algebras.

To study the etiology of acquired VWD. The patients referred from various hospitals in and out of Mumbai were included in the study. The differential diagnosis of AVWS was made based on reduced levels of von Willebrand antigen and von Willebrand ristocetin cofactor, decrease in ristocetin induced platelet aggregation, absence of correction in mixing studies with no prior history of bleeding problems and a negative family history for bleeding disorders.
In three patients, the disease was associated with systematic lupus erythematosus, out of which one was also associated with Kikuchi lymphadenitis and second with autoimmune hemolytic anemia. Fourth case was associated with hypothyroidism and fifth was a case of dermatitis and vitiligo.
The last patient was a case of hemophilia A with Burkitts lymphoma, who developed autoantibodies to von Willebrand factor. Except two patients, all other patients responded to immune suppressive therapy with corticosteroids, while the patient with hypothyroidism responded to oral thyroxine. AVWS is a rare condition and may often be missed or diagnosed as inherited disease associated with heterogeneous disease conditions.
Ecobalance of natural gas vehicles; Oekobilanz von Erdgasfahrzeugen. The impacts on human health and the natural environment of using natural gas, Diesel and petrol as fuels for city buses and passenger cars are compared in a Life Cycle Assessment.
Life in the Red Brigade pdf
In addition to the burning of the fuels in the engines, this assessment also comprises the upstream processes of the fuel supply chain. Despite the increased energy demand of the vehicles, natural gas is associated with the lowest impacts overall for both city buses and passenger cars. The health impacts that can be avoided through the use of natural gas instead of Diesel or petrol thereby differ only weakly between the use of the vehicles in cities of various sizes within Germany.
From the perspective of environmental protection, the market introduction of natural gas vehicles therefore does not need remain limited to large cities within agglomerated regions. Diese umfasst neben der motorischen Verbrennung der Kraftstoffe auch die vorgelagerten Prozessketten der Kraftstoffbereitstellung.

In particular, we lift the smooth entropy formalism as introduced by Renner and collaborators for finite-dimensional systems to von Neumann algebras. For the smooth conditional min- and max-entropy, we recover similar characterizing properties and information-theoretic operational interpretations as in the finite-dimensional case. We generalize the entropic uncertainty relation with quantum side information of Tomamichel and Renner and discuss applications to quantum cryptography.
In particular, we prove the possibility to perform privacy amplification and classical data compression with quantum side information modeled by a von Neumann algebra. Space the life of Wernher von Braun. Written by veteran aerospace journalist Bob Ward, who spent years investigating his subject, this biography presents a revealing but even-handed portrait of the father of modern rocketry.
As he chronicles Wernher von Braun's life, Ward explodes many myths and misconceptions about the controversial genius who was a hero to some, a villain to others. The picture of von Braun that emerges is of a brilliant scientist with limitless curiosity and a drive to achieve his goals at almost any price from, developing the world's first ballistic missile used against the Allies in World War II to help.

The first scientific understandings on the value of nutrition and the assimilation of food, in the Greek language "metabole" metabolism , are published in the Corpus Hippocraticum.
But the conception of metabolism was introduced in scientific literature not earlier than by Theodor Schwann and by Justus von Liebig The antique ideas were completed in the 17th century by the theory of ferments, introduced by the iatro-chemist Johann Baptist van Helmont , and the Italian priest Lazzaro Spallanzani could proof the existence of such processes in the living organism by animal experiments in Then Schwann could discover in the gastric juice a substance in which he called "pepsin".
In the time of the voyages of discovery new, not yet known malnutritions on the ships were known as scurvy, beriberi and in the northern countries rickets. Then it became clear that not only the three groups of food, but also supplementary materials, known in as vitamines by Casimir Funk , could develop determined effects.
The starvation in the first and the second world war showed clearly, that deterioration of food supply diminished the condition of immunity. Failed food experiments with gelatin, synthetically produced citric acid and the discussions of malnutrition diseases, based on a deficiency of zinc, of toddlers, are discussed as the malnutrition illness kwashiorkor in the third world. In conclusion a citation of the famous American physiologist Graham Lusk is mentioned from the year , who praised the scientific priority of the German medical research. Von -Neumann and Beyond: An extensive reliance on technology, an abundance of data, and increasing processing requirements have imposed severe challenges on computing and data processing.
Moreover, the roadmap for scaling electronic components faces physical and reliability limits that hinder the utilization of the transistors in conventional systems and promotes the need for faster, energy-efficient, and compact nano-devices. This work thus capitalizes on emerging non-volatile memory technologies, particularly the memristor for steering novel design directives. Moreover, aside from the conventional deterministic operation, a temporal variability is encountered in the devices functioning.
This inherent stochasticity is addressed as an enabler for endorsing the stochastic electronics field of study. We tackle this approach of design by proposing and verifying a statistical approach to modelling the stochastic memristors behaviour.
This mode of operation allows for innovative computing designs within the approximate computing and beyond Von -Neumann domains. In the context of approximate computing, sacrificing functional accuracy for the sake of energy savings is proposed based on inherently stochastic electronic components. We introduce mathematical formulation and probabilistic analysis for Boolean logic operators and correspondingly incorporate them into arithmetic blocks.
Gate- and system-level accuracy of operation is presented to convey configurability and the different effects that the unreliability of the underlying memristive components has on the intermediary and overall output. An image compression application is presented to reflect the efficiency attained along with the impact on the output caused by the relative precision quantification.
In contrast, in neuromorphic structures the memristors variability is mapped onto abstract models of the noisy and unreliable brain components. In one approach, we propose using the stochastic memristor as an inherent source of variability in. Eine Analyse mit den Daten des Partnermarktsurvey.

The English translation of the titles of the Aachen papers is given in Appendix I. Reflections on His Contributions to Space Exploration. Wernher von Braun and approximately of his team members came to Huntsville, Alabama, to begin work with the Army on what would later become America's historic space program. He would later serve as the first director of the Marshall Space Flight Center and led the development of the Saturn V launch vehicle that launched seven crewed American mission to the moon, as well as America s first space station, Skylab.
Von Braun is best known for his team s technical achievements. He realized his dream of exploring outer space by helping place humans on the moon. His engineering and managerial talent during the Apollo era had contributed to a technological revolution. He was by all accounts a good engineer, but he was only one among many. What set Von Braun apart were his charisma, his vision, and his leadership skills.
He inspired loyalty and dedication in the people around him. He understood the importance of communicating his vision to his team, to political and business leaders and the public. Today, the Marshall Center continues his vision by pursuing engineering and scientific projects that will continue to open space to exploration. This presentation will discuss Von Braun's impact on Huntsville, the Marshall Center, the nation and the world and look at his contributions in context of where world space exploration is today.

We show that there are games and decision situations in which it is not possible for the decision maker to be rational a la von Neumann-Morgenstern in both situations simultaneously, which is the source of the paradox presented in this note.
We provide an assumption which is the necessary and. Extensions of von Neumann's method for generating random variables. The flexibility of the power series methods is illustrated by algorithms for the Cauchy and geometric distributions. Computed tomography of von Meyenburg complex simulating micro-abscesses.
A case is presented of a bile duct hamartoma in a 44 year old man being evaluated for abdominal pain. The computed tomography CT findings suggested micro-abscesses in the liver and a CT guided tru-cut biopsy showed von Meyenburg complex. Ueber die arten und den Skelettbau von Culcita.
