Memory in a nonlocally damped oscillator

We analyze the new equation of motion for the damped oscillator. It differs from the standard one by a damping term which is nonlocal in time and hence it gives rise to a system with memory. Both classical and quantum analysis is performed. The characteristic feature of this nonlocal system is that it breaks local composition low for the classical Hamiltonian dynamics and the corresponding quantum propagator.Comment: minor corrections added; title change

The active site in a single-chain enzyme

The image visualizes a single-chain enzyme which, while largely accordant with the 3D Gaussian distribution, also contains a binding cavity. In terms of the fuzzy oil drop model the cavity manifests itself as a localized hydrophobicity deficiency. It encodes information which determines the function of the protein

The Benefits of University Faculty as P-12 Substitute Teachers

The current substitute teacher shortage was exacerbated by COVID-19 and is not expected to improve any time soon. A solution that may benefit both P-12 schools and higher education involves the occasional utilization of university faculty as substitute teachers. This alleviates some of the pressure on school districts in finding substitute teachers while also building relationships, providing university faculty with current classroom experience, and serving as a recruitment pipeline

Role of HogA and SskB protein kinases in mycotoxin production in the Filamentous Fungus Aspergillus nidulans

Includes bibliographical references.Aspergillus nidulans is a filamentous fungus that is often used as a model organism in genetics and molecular biology studies. The species has a well- characterized life-cycle and its genome has been sequenced. Aspergillus species are commonly found in the environment. Some species can cause health problems in humans. Some Aspergillus species produce aflatoxin, a toxic compound that causes acute necrosis, cirrhosis, and carcinoma of the liver in some animal species and can potentially cause similar symptoms in humans (Center for Integrated Fungal Research, 2005). A. nidulans produces the carcinogenic mycotoxin sterigmatocystin (ST), a precursor in the aflatoxin biosynthetic pathway (Adams, 1994). The focus of this project is to characterize the possible involvement of two A. nidulans stress- response protein kinases in the regulation of mycotoxin production. The two protein kinases under study are HogA and SskB. They are part of a phosphorelay system that senses osmotic and oxidative stress and triggers an adaptive response to these stimuli (Miskei, 2009). Our results suggest that the HogA pathway negatively regulates ST biosynthesis. This is the first study of the connection between elements of the HogA response pathway and the regulation of ST production.B.S. (Bachelor of Science

The Theatre versus the sacrum - an outline of the problem

A historian of theater constantly uses terms such as liturgical theater or religious theater with its many varieties. A person doing research on contemporary theater does not encounter these terms on a daily basis, but he can extend his knowledge by focusing on the presence of the phenomenon of "religiosity" in the theater, which presence, according to the suggestions of the contemporary anthropology of culture, is dubbed the sacrum. The secularization of the theater, resulting from a rather common secularization of life in economically developed countries, is a plain fact. This phenomenon, however, does not equal becoming distant form the sacrum. The need for the sacrum exists in the heart of man as his integral part and there is nothing to indicate that it should disappear. An overwhelming majority of artists, following the tendencies of the theater of the twentieth century, have touched on the theme of the sacrum in their pursuit of renewing the ritual, but it is happening by way of going back to the sources of the human community and to the sources of the theater rather than by way of going back to clearly defined values.Akademia Teatralna w Warszawie77-9

Zmiany integracji zabudowy mieszkaniowej ze stacją kolejową w latach 2012–2018 na tle rozwoju przestrzennego obszarów wiejskich poznańskiej strefy podmiejskiej

Jednym z podstawowych problemów rozwoju przestrzennego stref podmiejskich największych miast w Polsce jest niekontrolowana i chaotyczna forma suburbanizacji. Obszary te są szczególnie narażone na problemy komunikacyjne, dlatego też kluczową rolę pełni sprawny system transportu zbiorowego, a przede wszystkim kolej aglomeracyjna. Dlatego też głównym celem artykułu jest ocena integracji zabudowy mieszkaniowej ze stacją kolejową w poznańskiej strefie podmiejskiej oraz jej zmian na tle rozwoju przestrzennego w latach 2012 i 2018. Badania stref podmiejskich na gruncie geografii społeczno-ekonomicznej skupiały się do tej pory głównie na analizach funkcjonalno-przestrzennych i społecznych, stąd niniejszy artykuł stanowi uzupełnienie w tej kwestii

Creating an Electronic Document Center for NCATE Accreditation

This paper will discuss the development of the electronic document center (EDC) at the University of Central Missouri. It will highlight the initial assumptions and planning, discoveries made along the way, and thoughts and ideas as we reflect back on the process. It is hoped that sharing this insight will help those who will be preparing for their own site visits
