Modelling of the Phenomenon Known as “the Miracle of the Sun” as the Reflection of Light from Ice Crystals Oscillating Synchronously  [PDF]
Artur Wirowski
Journal of Modern Physics (JMP) , 2012, DOI: 10.4236/jmp.2012.33040
Abstract: The work includes a mathematical model of the phenomenon seen by the witnesses on 13th October, 1917 in the Cova da Iria near Fatima, and similar phenomena recorded in recent years throughout the world, known as the “miracle of the Sun”, allowing for qualitative and quantitative analysis of the phenomenon. The work includes a mathematical model of a cloud of the vibrating charged ice crystals. The paper shows the dynamic optical effects associated with the passage of light through such a vibrating medium. It also presents the simplest solution to the model in the form of graphs, which have been compared with the graphs obtained from the analysis of the amateur observations of the phenomenon in question.
Antibacterial activity of orsellinates
Gomes, Alcir Teixeira;Smania Júnior, Artur;Seidel, Cintia;Smania, Elza de Fátima Albino;Honda, Neli Kika;Roese, Fernanda Mesquita;Muzzi, Rozanna Marques;
Brazilian Journal of Microbiology , 2003, DOI: 10.1590/S1517-83822003000300002
Abstract: in order to obtain new compounds with antibacterial activity, the derivatives 2,4-dihydroxy-6-methylbenzoic acid (orsellinic acid) and 2,4-dihydroxy-6-methylbenzoates (orsellinates) were obtained through alcoholyses of lecanoric acid. all these substances were tested against gram-positive and gram-negative bacteria by a microdilution method. staphylococcus aureus, xanthomonas campestris var. vesicatoria and ralstonia solanacearum were most sensitive to n-propyl 2,4-dihydroxy-6-methylbenzoate, n-pentyl 2,4-dihydroxy-6-methylbenzoate and n-hexyl 2,4-dihydroxy-6-methylbenzoate with mic (minimal inhibitory concentration) values ranging from 62.5 to 7.8 μg×ml1. these results showed that homologation in carbon chain may lead to compounds with more pronunced activities.
Individual Counseling To Private Physicians Concerning Their Prescription Habits. A German Experience
Seidel J
Revue Médicale de l'Assurance Maladie , 2002,
Abstract: In order counteract ever-increasing prescription costs over the last few years combined with the precarious financial state of the health insurance fund of the German Land , Mecklembourg-Pomerany, the minister of social affairs, the health insurance fund and the Union of physicians contracting with the Land came to an agreement. The aim was to contain costs while guaranteeing that prescriptions remained of the highest quality. In order to accomplish this goal, the concerned players developed a common program of counseling and information directed at improving the prescription habits of private physicians. Beforehand, a pharmacy data bank (PLATO) had to be developed, permitting an analysis of the many aspects of the pharmacy prescriptions reimbursed by the health insurance fund. The article presents the preliminary results of this counseling and information-sharing initiative.

Design for an ageing population: promoting independence and quality of life
David Seidel
Australasian Medical Journal , 2009,
Abstract: Solutions to promote independent living in old age may occur at a systems level, where the health sciences,engineering and human factors work together. A better engineering response is needed directed at the problems encountered in the area of instrumental activities of daily living. Field studies can provide valuable insights, but surveydata are needed to complement and pinpoint areas for design improvement.
Design for health: transforming the way healthcare is delivered

Australasian Medical Journal , 2009,
Abstract: Design professionals use a variety of techniques to incorporate user experience into the design of products and services. Applying their techniques to healthcare could help to create an inclusive system that is functional, safe and satisfying.

Pfaffian statistics through adiabatic transport in the 1D coherent state representation
Alexander Seidel
Physics , 2008, DOI: 10.1103/PhysRevLett.101.196802
Abstract: Recent work has shown that the low energy sector of certain quantum Hall states is adiabatically connected to simple charge-density-wave patterns that appear, e.g., when the system is deformed into a thin torus. Here it is shown that the patterns emerging in this limit already determine the non-abelian statistics of the $\nu=1$ Moore-Read state. Aside from the knowledge of these patterns, the method only relies on the principle of adiabatic continuity, the effectively noncommutative geometry in a strong magnetic field, and topological as well as locality arguments.
S-duality constraints on 1D patterns associated with fractional quantum Hall states
Alexander Seidel
Physics , 2010, DOI: 10.1103/PhysRevLett.105.026802
Abstract: Using the modular invariance of the torus, constraints on the 1D patterns are derived that are associated with various fractional quantum Hall ground states, e.g. through the thin torus limit. In the simplest case, these constraints enforce the well known odd-denominator rule, which is seen to be a necessary property of all 1D patterns associated to quantum Hall states with minimum torus degeneracy. However, the same constraints also have implications for the non-Abelian states possible within this framework. In simple cases, including the $\nu=1$ Moore-Read state and the $\nu=3/2$ level 3 Read-Rezayi state, the filling factor and the torus degeneracy uniquely specify the possible patterns, and thus all physical properties that are encoded in them. It is also shown that some states, such as the "strong p-wave pairing state", cannot in principle be described through patterns.
