A six year old child with symmetric polydactyly of both hands and genu valgum deformity was referred for radiographic assessment. On physical examination, there were six digits in both hands with dysplastic finger nails. The upper and lower extremies were shortened out of proportions to the trunk with genu valgum deformity. Radiograph of hands revealed bifid 5th metacarpals and complete duplica...

In this work it was developed a Van de Graaff generator that we design and built and that is intended to be used in secondary schools for teaching basic principles of electrostatics, electromagnetic as well as a number of other applications. Today many schools laboratories and museums use this kind of generator for electrostatic demonstrations. Electrostatics was first noticed by the Greek phil...

Many cognitive activities are irreducibly social, involving interaction between several different agents. We look at some examples of this in linguistic communication and games, and show how logical methods provide exact models for the relevant information flow and world change. Finally, we discuss possible connections in this arena between logico-computational approaches and experimental cogni...

Background: Postexercise muscle glycogen synthesis is an important factor in determining the time needed to recover from prolonged exercise. Objective: This study investigated whether an increase in carbohydrate intake, ingestion of a mixture of protein hydrolysate and amino acids in combination with carbohydrate, or both results in higher postexercise muscle glycogen synthesis rates than does ...

the one-dimensional model of lippincott and schroeder for hydrogen bond has been re-examined and it has been shown that o-h bond distance depends on repulsive van der waals and attractive electrostatic potentials.it has been shown that constant b in the van der waals repulsion potential is not transferable to all hydrogen bonds. the possibility of obtaining the semi-empircal parameters in the l...

Abstract The SARS-CoV-2 outbreak and the corresponding COVID-19 pandemic has had continues to have a significant impact on health wellbeing of general population globally. University students are in unique position during as they confronted with substantial changes restrictions, both at governmental university-level. Stark lifestyle include social academic life.

Hypericin is a potent agent in the photodynamic therapy of cancers and accumulates to a large extent in tumor tissue. To better understand the impact of hypericin aggregates present in the delivery vehicle on the biodistribution of the compound, we compared the in vivo tissue accumulation after administering hypericin suspended as coarse aggregates in phosphate-buffered saline, with the biodist...

Software contains bugs and bugs cost money. A good way to find some bugs quickly is the use of static code analysis. There are no exact numbers on the use of static code analyzers in the industry, but in our experience to few software developers actually make use of them. This thesis describes a survey that was conducted to find out why only so few developers in the Java community use static co...

Bei Springer blicken wir inzwischen auf eine dreijährige Open-Access Erfahrung zurück. In meinem Beitrag werde ich das spezifische Springer-Modell unter dem Namen Open Choice kurz darstellen und erläutern, wie es im wissenschaftlichen Umfeld angenommen und genutzt wird. Ich werde auch am konkreten Beispiel der Max-Planck-Gesellschaft umreißen, wie wir in einem Pilotprojekt Zeitschriftenabonneme...
