Time-resolved X-ray absorption spectroscopy (TR-XAS) possesses excellent capabilities to reveal quantitative phase composition and average valence together with the evolution of the local structure of a system under dynamic reaction conditions. The work discussed here focused on time-resolved in-situ XAS investigations aiming, first, at understanding structural evolution under dynamic condition...

We investigate which general results concerning the local stability of steady states of arbitrary chemical reaction networks can be deduced with the Glansdorff–Prigogine stability criterion. Especially, it is proven that the presence of an autocatalytic reaction is not a necessary condition for a violation of the thermodynamic stability condition. It turns out that every reaction with at least ...

Some dental patients have histories of adverse reactions to local anesthesia. The aim of the present study was to investigate the frequency of allergy to local anesthetics of dental patients who had histories of adverse reactions to local anesthesia based on the results of allergy tests in our institute over a period of 5 years. We investigated the past medical records of dental patients retros...

BACKGROUND Local reactions are the most commonly reported adverse events following tetanus and diphtheria toxoid (Td) vaccine and the risk of local reactions may increase with number of prior Td vaccinations. METHODS To estimate the risk of medically attended local reactions following Td vaccination in adolescents and young adults we conducted a six-year retrospective cohort study assessing 4...

We show that models for orientation map formation, which invoke convolution in the dynamic equation, are in fact invoking non-local reaction diffusion. In the early stages of development it is unlikely that non-local interactions take place. We present a non-linear reaction diffusion model based on near neighbour interaction for formation of orientation map. Besides capturing all the essential ...

Studies are reported on the effect of immunologically induced thrombocytopenia upon the local and generalized Shwartzman phenomena. Intravenous injection of antiplatelet serum to rabbits produced profound but transient thrombocytopenia unaccompanied by significant changes in circulating leucocytes. Platelet antiserum alone given to rabbits prepared with thorotrast produced renal lesions charact...

The brain as a functional unit in the production of generalized anaphylaxls has been extensively studied, notably by Besredka (1). As the seat of a local allergic reaction, however, it has apparently not yet been examined. Since the local anaphylactic reaction in the skin and in various organs (2) consists of edema, hemorrhage, and leucocytic infiltration, it appeared likely that the nervous ti...

the present article discusses the reaction of psychiatric professionals and specifically the academia in iran to the publication of the diagnostic and statistical manual of mental disorders, fifth edition, (dsm-5). it is argued that the reaction to changes and the approach of the new revision of dsm has been neither technical, nor emotional. this argument has further been examined for the previ...

Molecular computing executed via local interactions of spatially contiguous sets of molecules has potential advantages of (i) speed due to increased local concentration of reacting species, (ii) generally sharper switching behavior and higher precision due to single molecule interactions, (iii) parallelism since each circuit operates independently of the others and (iv) modularity and scalabili...
