Long-term orbital period behaviour of contact binaries V343 Ori and FZ Ori
No full text32nd International Physics Congress of Turkish-Physical-Society (TPS) -- SEP 06-09, 2016 -- Bodrum, TURKEYIn this study, we investigated orbital period variations of two contact binaries V343 Ori and FL Ori based on published minima times. Using the O-C analysis, it was found that both systems indicate orbital period increase. Mass transfer from less massive component to more massive component was used to explain increases in the orbital periods. On the other hand, the secular changes in their periods can be a sign of the thermal relaxation oscillation. In the O-C diagram of FL Ori, periodic variations also exist. Cyclic periodic changes can be explained as being the result of a light travel time effect via a tertiary body around the eclipsing pair. The minimum mass of probable tertiary component around FL Ori was found to be 0.63 M-circle dot. In addition, the cyclic variation may be evidence of magnetic activity of the components, which are late-type stars.Turkish Phys So

Creating culturally-safe schools for Māori students
No full textIn order to better understand the present trends in New Zealand’s schooling contexts, there is a clarion call for educators to develop sensitivity and sensibility towards the cultural backgrounds and experiences of Māori students. This paper reports on the work of four scholars who share research that has been undertaken in educational settings with high numbers of Māori students, and discusses the importance of creating culturally-safe schools – places that allow and enable students to be who and what they are. The theoretical frameworks drawn on are based on both a life partnership analogy as well as on a socio-cultural perspective on human development and learning. The Māori worldview presented in this paper is connected to the Treaty of Waitangi, The Educultural Wheel and the Hikairo Rationale. Data were collected from two ethnographic case studies and analysed through these frameworks. Practical suggestions are then made for using restorative practices and creating reciprocal relationships in classrooms within an environment of care. The paper reports on an evidence-based approach to creating culturally-safe schools for Māori students

The discovery of SycO reveals a new function for type three secretion effector chaperones
No full textThe Type Three Secretion (T3S) system is a device used by many Gram-negative pathogens that allows bacteria to deliver effector proteins straight into the eukaryotic cell cytosol. These effectors interfere with various signaling pathways to subvert the host cell functions. The secretion machinery of the T3S system consist of a basal body spanning the bacterial inner and outer membrane followed by a stiff hollow needle outside the bacterium. The fully assembled secretion apparatus constitute a continuous hollow conduit that connects the bacteria to the eukaryotic target cell. After cell contact, virulence proteins -called effectors- are injected directly into the cytosol of the host cell via the T3S apparatus. Several effectors of the T3S system require the assistance of specific cytosolic chaperones to be efficiently exported. There are three classes of T3S chaperones. Effector proteins are assisted by Class I chaperones. Although Class I chaperones are well characterized, their main function is still a matter of controversy. In this thesis, we demonstrate that orf155 encodes a specific chaperone for the effector YopO that we called SycO. We showed that SycO enhances YopO secretion in vitro and is required for translocation of YopO into infected cells. By pulldown assay we demonstrated that residues 20 to 77 of YopO are required and sufficient for SycO binding. Using crosslinking experiments and size exclusion chromatography analysis, we determined the stoichiometry of purified SycO and YopO-SycO complexes. SycO alone forms dimers in solution and the YopO-SycO complex has a 1:2 stoichiometry. These results suggested that SycO is a typical chaperone of the Class I. YopO is a serine/theronine kinase that interacts with Rho and Rac and disrupts the cytoskeleton of the target cells. YopO has been shown to localize at the cell plasma-membrane. By transfection of YopO-EGFP hybrid proteins into HEK293T cells, we demonstrated that the chaperone-binding domain (CBD) coincides with the membrane localization domain of YopO. Nevertheless, the CBD was not needed for the kinase activity of YopO. By ultracentrifugation, we also showed that the CBD causes YopO aggregation in the bacteria, when SycO does not cover it. Further, we show that the CBD of YopE and YopT also caused aggregation in the bacteria in the absence of SycE and SycT respectively. YopE, YopT and T3S effectors in other systems also act at the membrane of the eukaryotic host cell. We propose a new hypothesis concerning the role of T3S chaperones. The sub-cellular localization domain of effectors is aggregation-prone and creates the need for a chaperone inside bacteria. We propose that masking such aggregation-prone localization domains may be a general function for type III effector chaperones
Escuela en acción infantil : revista de pedagogía de magisterio
No full textSe cita una serie de actividades realizadas en la Escuela de Educación Infantil Ori-Ori que pretenden promover la integración social de todas las nacionalidades presentes en el centro sin perder por ello su identidad y raíces. Las experiencias educativas realizadas, en este sentido, se caracterizan por ser globalizadoras, creativas, motivantes, lúdicas, flexibles y socializadoras. Algunas de estas actividades son talleres de música y cocina, fiestas o semanas interculturales. En definitiva, se trata de promover el conocimiento de la cultura propia y la ajena así como la convivencia pacífica y respetuosa entre ellas.ES
Apsidal motion of two eclipsing binaries: V796 Cyg and V2783 Ori
No full text32nd International Physics Congress of Turkish-Physical-Society (TPS) -- SEP 06-09, 2016 -- Bodrum, TURKEYIn this study, the orbital period variations of two eclipsing binary systems showing apsidal motion were studied. Their O - C diagrams were analysed using all reliable eclipse timings and the elements of apsidal motion of two systems were improved. We found periods of apsidal motion of V796 Cyg and V2783 Ori to be 32.7 +/- 0.2 years and 415 +/- 50 years, respectively.Turkish Phys So
