Ceiling-fan-integrated air conditioning: Airflow and temperature characteristics of a sidewall-supply jet interacting with a ceiling fan

Ceiling-Fan-Integrated Air Conditioning (CFIAC) is a proposed system that can greatly increase buildings’ cooling efficiency. In it, terminal supply ducts and diffusers are replaced by vents/nozzles, jetting supply air toward ceiling fans that serve to mix and distribute it within the room. Because of the fans’ air movement, the system provides comfort at higher room temperatures than in conventional commercial/ institutional/retail HVAC. We have experimentally evaluated CFIAC in a test room. This paper covers the distributions of air-speed, temperature, and calculated comfort level throughout the room. Two subsequent papers report tests of human subject comfort and ventilation effectiveness in the same experimental conditions. The room’s supply air emerged from a high-sidewall vent directed toward a ceiling fan on the jet centerline; we also tested this same jet on a fan located off to the side of the jet. Primary variables are: ceiling fan flow volumes in downward and upward directions, supply air volume, and room-vs-supply temperature difference. Velocity, turbulence, and temperature distributions are presented for vertical and horizontal transects of the room. The occupied zone is then evaluated for velocity and temperature non-uniformity, and for comfort as predicted by the ASHRAE Standard 55 elevated air speed method. We show that temperatures are well-mixed and uniform across the room for all of the fan-on configurations, for fans both within or out of the supply jet centerline. The ceiling fan flow dominates the CFIAC airflow, and even though non-uniform is capable of providing comfortable conditions throughout the occupied area of the room

“They have it better there” : Chinese Migrant Teachers’ Beliefs, Imaginaries and Ideologies in Cross-national Comparisons

This paper was written in response to a growing need to address the perceptions and experiences of teachers of migrant background. Based on a critical intercultural theoretical perspective, which moves beyond typical ‘culture shock’ and ‘adaptation’ models of understanding and explaining migrants’ experiences, this paper makes use of the concepts of teacher beliefs, ideologies and imaginaries (Holliday, 2010) in considering how Finland-based Chinese migrant teachers perceive the position of being teachers of Chinese in Finland and Australia. Analysis of data from group discussions during a teacher training workshop indicates that these teachers constructed a “utopia” (Australia) and “dystopia” (Finland) Chinese language teaching, and reveals that multiple factors have influenced these migrant teachers’ perceptions and experiences. Findings provide information for e.g. teacher educators and stakeholders to better understand and support migrant teachers from various linguistic and cultural backgrounds.Peer reviewe

Transcriptional regulation of PIN genes by FOUR LIPS and MYB88 during Arabidopsis root gravitropism

PIN proteins are auxin export carriers that direct intercellular auxin flow and in turn regulate many aspects of plant growth and development including responses to environmental changes. The Arabidopsis R2R3-MYB transcription factor FOUR LIPS (FLP) and its paralogue MYB88 regulate terminal divisions during stomatal development, as well as female reproductive development and stress responses. Here we show that FLP and MYB88 act redundantly but differentially in regulating the transcription of PIN3 and PIN7 in gravity-sensing cells of primary and lateral roots. On the one hand, FLP is involved in responses to gravity stimulation in primary roots, whereas on the other, FLP and MYB88 function complementarily in establishing the gravitropic set-point angles of lateral roots. Our results support a model in which FLP and MYB88 expression specifically determines the temporal-spatial patterns of PIN3 and PIN7 transcription that are closely associated with their preferential functions during root responses to gravity

The Impact of IT Developments on Space Usage in Manukau Institute of Technology (MIT) Library

There are numerous claims of whether physical spaces of academic libraries still required as more resources moved from print to electronic. This project set out to investigate the impact of IT developments on space usage in Manukau Institute of Technology (MIT) Library in order to help librarians and space planners to manage the physical spaces better, and improve existing spaces. They will be able to make informed decisions when planning for future use of spaces. A web based questionnaire was used to collect data on who was using the library and the activities in which they are engaged. There were 261 complete responses to the questionnaire. The researcher also conducted interviews with the Associate Librarian and the Institute Librarian from MIT Library on asking them how they have planed and managed the physical spaces in MIT Library. In addition, the researcher also examined the MIT Library statistics: Data in relations to volumes of print serial and monograph acquired, total number of issues, total number of library visits, total reference enquiries from 2003 to 2008 was analysed and then presented in charts, graphs and tables. The majority of respondents from the online questionnaire were found to be undergraduate fulltime students between the age of 20-25, and they were mainly female students. More than half of the respondents reported they can easily find the place to carry out individual study and group work. However, some respondents commented that in certain times of the year (for example, assignments/exams period) it is very difficult to find a place for individual study and/or group work. The majority of the respondents also reported they mainly come to the library to work on their assignments and study for tests/exams. The Institute Librarian and Associate Librarian mentioned that instead of just storing print materials, the physical spaces is also required to house more computers to access online resources, for quiet study space and group study rooms, and to provide more electrical outlets to access wireless using laptops. The conclusion reached was that the physical spaces of MIT Library still remains essential even through more resources has moved from print to electronic

Bioengineered Bruch's-like extracellular matrix promotes retinal pigment epithelial differentiation

In the eye, the retinal pigment epithelium (RPE) adheres to a complex protein matrix known as Bruch's membrane (BrM). The aim of this study was to provide enriched conditions for RPE cell culture through the production of a BrM-like matrix. Our hypothesis was that a human RPE cell line would deposit an extracellular matrix (ECM) resembling BrM. The composition and structure of ECM deposited by ARPE19 cells (ARPE19-ECM) was characterized. To produce ARPE19-ECM, ARPE19 cells were cultured in the presence dextran sulphate. ARPE19-ECM was decellularized using deoxycholate and characterized by immunostaining and western blot analysis. Primary human RPE and induced pluripotent stem cells were seeded onto ARPE19-ECM or geltrex coated surfaces and examined by microscopy or RT-PCR. Culture of ARPE19 cells with dextran sulphate promoted nuclear localization of SOX2, formation of tight junctions and deposition of ECM. ARPE19 cells deposited ECM proteins found in the inner layers of BrM, including fibronectin, vitronectin, collagens IV and V as well as laminin-alpha-5, but not those found in the middle elastic layer (elastin) or the outer layers (collagen VI). ARPE19-ECM promoted pigmentation in human RPE and pluripotent stem cell cultures. Expression of RPE65 was significantly increased on ARPE19-ECM compared with geltrex in differentiating pluripotent stem cell cultures. ARPE19 cells deposit ECM with a composition and structure similar to BrM in the retina. Molecular cues present in ARPE19-ECM promote the acquisition and maintenance of the RPE phenotype. Together, these results demonstrate a simple method for generating a BrM-like surface for enriched RPE cell cultures
