Krefelderski test - novi eksperimentalni postupak za proučavanje toksičnosti kemikalija
During the last years, skin compatibility of textiles has gained importance for consumers. Therefore, the development of suitable test methods for the evaluation of skin compatibility is a vital challenge. The fundamental requirements for these test methods are low experimental complexity combined with minor costs. The Cilitatetest has been developed for the cosmetic and pharmaceutics industry. Due to the optical measurement of the number of living microorganisms, this method is not suitable for colored or heterogeneous samples. However, using a calorimetric detection, these problems are resolved. This method allows very sensitive detection of the metabolism of the microorganism. The presence of any toxic substance results in a reduction of the heat of metabolism.Kompatibilnost tekstila prema koži postajala je tijekom posljednjih godina sve važnija potrošačima. Zato je razvoj prikladnih postupaka ispitivanja za prosudbu kompatibilnosti s kožom primjeran izazov. Osnovni zahtjev postavljen za ove postupke ispitivanja jest eksperimentalna jednostavnost povezana s nižim troškovima. Ispitivanje trepetljikašima razvijeno je za kozmetičku i farmaceutsku industriju. Zbog optičkog mjerenja broja živih mikroorganizama taj postupak nije prikladan za obojene ili heterogene uzorke. Međutim, ti problemi su riješeni primjenom kalorimetijskog otkrivanja. Taj postupak otkrivanja omogućuje vrlo osjetljivo prepoznavanje metabolizma mikroorganizama. Postojanje bilo koje otrovne tvari znači smanjenje topline metabolizm
Molecular dynamics simulations of the dipolar-induced formation of magnetic nanochains and nanorings
Iron, cobalt and nickel nanoparticles, grown in the gas phase, are known to
arrange in chains and bracelet-like rings due to the long-range dipolar
interaction between the ferromagnetic (or super-paramagnetic) particles. We
investigate the dynamics and thermodynamics of such magnetic dipolar
nanoparticles for low densities using molecular dynamics simulations and
analyze the influence of temperature and external magnetic fields on two- and
three-dimensional systems. The obtained phase diagrams can be understood by
using simple energetic arguments.Comment: 6 pages, 6 figure
Medida de la humedad en el hormigón
Not availablePara medir el contenido de humedad del hormigón se conocen varios métodos, además del procedimiento gravimétrico, los cuales difieren unos de otros tanto en lo que se refiere a su exactitud como a su viabilidad. Dentro de un programa de investigaciones, los autores han tenido que resolver el problema de la realización de medidas de larga duración en elementos de hormigón de grandes dimensiones. Con el fin de obtener una visión de conjuntó sobre las experiencias adquiridas por la aplicación de los diferentes métodos, se ha remitido un cuestionario a un cierto número de institutos y con el aval del RILEM. En el presente trabajo se hace un análisis de las contestaciones recibidas. Del estudio de estas respuestas y teniendo en cuenta la literatura sobre el tema, de la cual se da aquí una amplia referencia, se llega a la conclusión de que todavía no se dispone de un método universal para la medida del contenido de humedad

Brain inflammation plays a central role in multiple sclerosis (MS). Besides lymphocytes, the astroglia and microglia mainly contribute to the cellular composition of the inflammatory infiltrate in MS lesions. Several studies were able to demonstrate that cortical lesions are characterized by lower levels of inflammatory cells among activated microglia/macrophages. The underlying mechanisms for this difference, however, remain to be clarified. In the current study, we compared the kinetics and extent of microglia and astrocyte activation during early and late cuprizone-induced demyelination in the white matter tract corpus callosum and the telencephalic gray matter. Cellular parameters were related to the expression profiles of the chemokines Ccl2 and Ccl3. We are clearly able to demonstrate that both regions are characterized by early oligodendrocyte stress/apoptosis with concomitant microglia activation and delayed astrocytosis. The extent of microgliosis/astrocytosis appeared to be greater in the subcortical white matter tract corpus callosum compared to the gray matter cortex region. The same holds true for the expression of the key chemokines Ccl2 and Ccl3. The current study defines a model to study early microglia activation and to investigate differences in the neuroinflammatory response of white vs. gray matter
A Catalog of Architectural Tactics for Cyber-Foraging
Mobile devices have become for many the preferred way of interacting with the Internet, social media and the enterprise. However, mobile devices still do not have the computing power or battery life that will allow them to perform effectively over long periods of time or for executing applications that require extensive communication or computation, or low latency. Cyber-foraging is a technique enabling mobile devices to extend their computing power and storage by offloading computation or data to more powerful servers located in the cloud or in single-hop proximity. This paper presents a catalog of architectural tactics for cyber-foraging that was derived from the results of a systematic literature review on architectures for cyber-foraging systems. Elements of the architectures identified in the primary studies were codified in the form of Architectural Tactics for Cyber-Foraging. These tactics will help architects extend their design reasoning towards cyber-foraging as a way to support the mobile applications of the present and the future
