  5. Science Professional Learning Communities: Beyond a singular view of teacher professional development

    NASA Astrophysics Data System (ADS)

    Jones, M. Gail; Gardner, Grant E.; Robertson, Laura; Robert, Sarah

    2013-07-01

    Professional Learning Communities (PLCs) are frequently being used as a vehicle to transform science education. This study explored elementary teachers' perceptions about the impact of participating in a science PLC on their own professional development. With the use of The Science Professional Learning Communities Survey and a semi-structured interview protocol, elementary teachers' perceptions of the goals of science PLCs, the constraints and benefits of participation in PLCs, and reported differences in the impact of PLC participation on novice and experienced teachers were examined. Sixty-five elementary teachers who participated in a science PLC were surveyed about their experiences, and a subsample of 16 teachers was interviewed. Results showed that most of the teachers reported their science PLC emphasized sharing ideas with other teachers as well as working to improve students' science standardized test scores. Teachers noted that the PLCs had impacted their science assessment practices as well as their lesson planning. However, a majority of the participants reported a differential impact of PLCs depending on a teacher's level of experience. PLCs were reported as being more beneficial to new teachers than experienced teachers. The interview results demonstrated that there were often competing goals and in some cases a loss of autonomy in planning science lessons. A significant concern was the impact of problematic interpersonal relationships and communication styles on the group functioning. The role of the PLC in addressing issues related to obtaining science resources and enhancing science content knowledge for elementary science teachers is discussed.

  14. Science-for-Teaching Discourse in Science Teachers' Professional Learning Communities

    NASA Astrophysics Data System (ADS)

    Lohwasser, Karin

    Professional learning communities (PLCs) provide an increasingly common structure for teachers' professional development. The effectiveness of PLCs depends on the content and quality of the participants' discourse. This dissertation was conducted to add to an understanding of the science content needed to prepare to teach science, and the discourse characteristics that create learning opportunities in teachers' PLCs. To this end, this study examined how middle school science teachers in three PLCs addressed science-for-teaching, and to what effect. Insight into discourse about content knowledge for teaching in PLCs has implications for the analysis, interpretation, and support of teachers' professional discourse, their collaborative learning, and consequently their improvement of practice. This dissertation looked closely at the hybrid space between teachers' knowledge of students, of teaching, and of science, and how this space was explored in the discourse among teachers, and between teachers and science experts. At the center of the study were observations of three 2-day PLC cycles in which participants worked together to improve the way they taught their curriculum. Two of the PLC cycles were supported, in part, by a science expert who helped the teachers explore the science they needed for teaching. The third PLC worked without such support. The following overarching questions were explored in the three articles of this dissertation: (1) What kind of science knowledge did teachers discuss in preparation for teaching? (2) How did the teachers talk about content knowledge for science teaching, and to what effect for their teaching practice? (3) How did collaborating teachers' discursive accountabilities provide opportunities for furthering the teachers' content knowledge for science teaching? The teachers' discourse during the 2-day collaboration cycles was analyzed and interpreted based on a sociocultural framework that included concepts from the practice-based theory of content knowledge for teaching developed by D. L. Ball, Thames, and Phelps (2008) and the Accountable Talk framework by Michaels, O'Connor, & Resnick (2008). The study's findings could provide justification for and ideas on how to provide targeted support for PLCs to make teachers' work on science knowledge more applicable to lesson planning, teaching, and student learning.

  7. Change Management in Dental Education: A Professional Learning Community.

    PubMed

    Palatta, Anthony M

    2018-06-01

    Professional learning communities (PLCs) are defined as "a group of people sharing and critically interrogating their practice in an ongoing, reflective, collaborative, inclusive, learning-oriented, growth-promoting way." PLCs have been found to be an effective change management strategy in business and education when confronted by rapid change. The American Dental Education Association's Commission on Change and Innovation in Dental Education new national program-ADEA CCI 2.0-includes the development of a PLC. By employing an "engage and learn" model PLC centered on continuous quality improvement and systems thinking, dental faculty can identify internal and external barriers to change that could lead to innovative solutions to complex issues. This article argues that a PLC is a viable change management strategy to counteract the effect of multiple external forces impacting dental education and thus to develop future-ready faculty.

  18. The negotiation of meaning and exercise of power in professional learning communities: An investigation of middle school science teachers

    NASA Astrophysics Data System (ADS)

    Mclaughlin, Cheryl Althea

    A professional learning community (PLC) typically consists of practitioners who systematically examine and problematize their practice with the intention of development and improvement. The collaborative practices inherent in PLCs mirror the way scientists work together to develop new theories, and are particularly valuable for science teachers who could draw from these experiences to improve the quality of student learning. Gaps in the science education literature support the need for research to determine how interactions within PLCs support science teacher development. Additionally, issues of power that may constrain or encourage meaningful interactions are largely overlooked in PLC studies. This qualitative study examines, from a Foucauldian perspective, interactions within a PLC comprising middle school science teachers preparing to implement reform curriculum. Specifically, the study analyzes interactions within the PLC to determine opportunities created for professional learning and development. Audiotaped transcripts of teacher interactions were analyzed using discourse analysis building tasks designed to identify opportunities for learning and to examine the exercise of power within the PLCs. The discourse analytical tools integrated theories of Gee (2011) and Foucault (1972), and were used to deconstruct and interrogate the data. The events were subsequently reconstructed through the lens of social constructivism and Foucault theories on power. The findings identified several processes emerging from the interactions that contributed to the negotiation of an understanding of the reform curriculum. These include reflection on practice, reorganization of cognitive structures, reinvention of practice, and refinement of instructional strategies. The findings also indicated that the exercise of power by entities both external to, and within the PLCs influenced the process of meaning negotiation among the science teachers. The consensus achieved by the teachers reflected knowledge constructed by science education discourses external to the PLC, which regulated understandings emerging from the interactions. Additionally, some teachers, through their actions, exercised power in ways that hindered rather than enhanced constructive dialogue in PLCs. The exercise of power by external institutions was nevertheless necessary to set the stage for the series of actions, the outcome of which facilitated constructive dialogue among science teachers who were implementing the reform curriculum.

  15. The professional learning community as perceived by Israeli school superintendents, principals and teachers

    NASA Astrophysics Data System (ADS)

    Schechter, Chen

    2012-12-01

    A professional learning community (PLC) facilitates collaborative learning among colleagues at all levels in their common working environment. PLCs are particularly useful in schools, with teachers and principals meeting regularly to solve problems relating to teaching and learning. Being a means of improving student achievement, PLCs have received growing support from researchers and practitioners alike, yet some professionals are still exploring ways to develop learning networks focusing on teaching and learning issues. The purpose of this study was to examine Israeli teachers', principals', and superintendents' perceptions of inhibiting and fostering factors of the PLC. In this qualitative, topic-oriented study, face-to-face interviews were conducted with 15 teachers from elementary, middle and secondary schools and their respective principals (15) and superintendents (15). Generating themes was inductive, grounded in the perspectives articulated by participants. The principals and the teachers indicated that overload, a lack of resources and top-down commands were PLC-inhibiting factors. The superintendents saw the principal's leadership style as a main PLC-fostering factor. Understanding how these three echelons in the school system perceive the inhibiting and fostering factors of a PLC could indicate whether and how this collaborative learning process can be nurtured and sustained in schools.

  9. Professional Learning Communities (PLCs) as a Means for School-Based Science Curriculum Change

    NASA Astrophysics Data System (ADS)

    Browne, Christi L.

    The challenge of school-based science curriculum change and educational reform is often presented to science teachers and departments who are not necessarily prepared for the complexity of considerations that change movements require. The development of a Professional Learning Community (PLC) focused on a science department's curriculum change efforts, may provide the necessary tools to foster sustainable school-based curriculum science changes. This research presents a case study of an evolving science department PLC consisting of 10 middle school science teachers from the same middle school and their efforts of school-based science curriculum change. A transformative mixed model case study with qualitative data and deepened by quantitative analysis, was chosen to guide the investigation. Collected data worked to document the essential developmental steps, the occurrence and frequency of the five essential dimensions of successful PLCs, and the influences the science department PLC had on the middle school science department's progression through school-based science curriculum change, and the barriers, struggles and inhibiting actions of the science department PLC. Findings indicated that a science department PLC was unique in that it allowed for a focal science departmental lens of science curriculum change to be applied to the structure and function of the PLC and therefore the process, proceedings, and results were directly aligned to and driven by the science department. The science PLC, while logically difficult to set-up and maintain, became a professional science forum where the middle school science teachers were exposed to new science teaching and learning knowledge, explored new science standards, discussed effects on student science learning, designed and critically analyzed science curriculum change application. Conclusions resulted in the science department PLC as an identified tool providing the ability for science departmental actions to lead to outcomes of science curriculum change improvements with the consideration but not the dictation of the larger school community and state agendas. Thus, the study's results work to fuse previously separated research on general PLCs and curriculum change efforts into a cohesive understanding of the unexplored potential of a science PLC and school-based science curriculum change.

    The Lifelines project aims to establish a network of practicing high school teachers actively using climate change curricula by creating professional learning communities (PLCs) of teachers who, through remote meetings and workshops, maintain ongoing communication and sharing of best practices among colleagues to strengthen knowledge and promote effective teaching strategies. The project explores techniques to achieve the most effective teleconferencing meetings and workshops. This promotes not only teaching about minimizing environmental impacts of human activity, but minimizes environmental impacts of professional development — practicing what we preach. To date, Lifelines PLCs have set up websites and e-mail lists for sharing information. Teleconferences and webinars have been held using services such as Skype, ReadyTalk, and Wiggio. Many of the meetings have been recorded and archived for the benefit of members who could not attend in real-time.

  12. Measuring the utility of the Science, Technology, Engineering, Mathematics (STEM) Academy Measurement Tool in assessing the development of K-8 STEM academies as professional learning communities

    NASA Astrophysics Data System (ADS)

    Irish, Teresa J.

    The aim of this study was to provide insights addressing national concerns in Science, Technology, Engineering, and Mathematics (STEM) education by examining how a set of six perimeter urban K-12 schools were transformed into STEM-focused professional learning communities (PLC). The concept of a STEM Academy as a STEM-focused PLC emphasizes the development of a STEM culture where professional discourse and teaching are focused on STEM learning. The STEM Academies examined used the STEM Academy Measurement Tool and Rubric (Tool) as a catalyst for discussion and change. This Tool was developed with input from stakeholders and used for school-wide initiatives, teacher professional development and K-12 student engagement to improve STEM teaching and learning. Two primary goals of this study were to assess the levels of awareness and use of the tool by all stakeholders involved in the project and to determine how the Tool assisted in the development and advancement of these schools as STEM PLCs. Data from the STEM Academy Participant Survey was analyzed to determine stakeholders' perceptions of the Tool in terms of (i) how aware stakeholders were of the Tool, (ii) whether they participated in the use of the Tool, (iii) how the characteristics of PLCs were perceived in their schools, and finally (iv) how the awareness of the Tool influenced teachers' perceptions of the presence of PLC characteristics. Findings indicate that school faculty were aware of the Tool on a number of different levels and evidence exists that the use of the Tool assisted in the development of STEM Academies, however impact varied from school to school. Implications of this study suggest that the survey should be used for a longer period of time to gain more in-depth knowledge on teachers' perceptions of the Tool as a catalyst across time. Additional findings indicate that the process for using the Tool should be ongoing and involve the stakeholders to have the greatest impact on school culture. This research contributes to the knowledge base related to building STEM PLCs aimed at improving K-12 teacher content and pedagogical knowledge as well as student learning and achievement in STEM education.

  13. Professional learning communities (PLCs) for early childhood science education

    NASA Astrophysics Data System (ADS)

    Eum, Jungwon

    This study explored the content, processes, and dynamics of Professional Learning Community (PLC) sessions. This study also investigated changes in preschool teachers' attitudes and beliefs toward science teaching after they participated in two different forms of PLCs including workshop and face-to-face PLC as well as workshop and online PLC. Multiple sources of data were collected for this study including participant artifacts and facilitator field notes during the PLC sessions. The participants in this study were eight teachers from NAEYC-accredited child care centers serving 3- to 5-year-old children in an urban Midwest city. All teachers participated in a workshop entitled, "Ramps and Pathways." Following the workshop, the first group engaged in face-to-face PLC sessions and the other group engaged in online PLC sessions. Qualitative data were collected through audio recordings, online archives, and open-ended surveys. The teachers' dialogue during the face-to-face PLC sessions was audiotaped, transcribed, and analyzed for emerging themes. Online archives during the online PLC sessions were collected and analyzed for emerging themes. Four main themes and 13 subthemes emanated from the face-to-face sessions, and 3 main themes and 7 subthemes emanated from the online sessions. During the face-to-face sessions, the teachers worked collaboratively by sharing their practices, supporting each other, and planning a lesson together. They also engaged in inquiry and reflection about their science teaching and child learning in a positive climate. During the online sessions, the teachers shared their thoughts and documentation and revisited their science teaching and child learning. Five themes and 15 subthemes emanated from the open-ended survey responses of face-to-face group teachers, and 3 themes and 7 subthemes emanated from the open-ended survey responses of online group teachers. Quantitative data collected in this study showed changes in teachers' attitudes and beliefs toward science teaching. Face-to-face group teachers' comfort with planning and doing different science activities increased significantly after the workshop and after the combination of workshop and face-to-face PLC. This study contributes to the research about various forms of professional development and their process and outcome in early childhood science education and informs early childhood professional communities of creative ways to improve science teaching and learning.

  14. Global Systems Science and Hands-On Universe Course Materials for High School

    NASA Astrophysics Data System (ADS)

    Gould, A.

    2011-09-01

    The University of California Berkeley's Lawrence Hall of Science has a project called Global Systems Science (GSS). GSS produced a set of course materials for high school science education that includes reading materials, investigations, and software for analyzing satellite images of Earth focusing on Earth systems as well as societal issues that require interdisciplinary science for full understanding. The software has general application in analysis of any digital images for a variety of purposes. NSF and NASA funding have contributed to the development of GSS. The current NASA-funded project of GSS is Lifelines for High School Climate Change Education (LHSCCE), which aims to establish professional learning communities (PLCs) to share curriculum resources and best practices for teaching about climate change in grades 9-12. The project explores ideal ways for teachers to meet either in-person or using simple yet effective distance-communication techniques (tele-meetings), depending on local preferences. Skills promoted include: how to set up a website to share resources; initiating tele-meetings with any available mechanism (webinars, Skype, telecons, moodles, social network tools, etc.); and easy ways of documenting and archiving presentations made at meetings. Twenty teacher leaders are forming the PLCs in their regions or districts. This is a national effort in which teachers share ideas, strategies, and resources aimed at making science education relevant to societal issues, improve students' understanding of climate change issues, and contribute to possible solutions. Although the binding theme is climate change, the application is to a wide variety of courses: Earth science, environmental science, biology, physics, and chemistry. Moreover, the PLCs formed can last as long as the members find it useful and can deal with any topics of interest, even if they are only distantly related to climate change.

    Luteal cells play a crucial role in pregnancy through secreting progesterone to maintain pregnancy and support of fetus. However, low cellular yields and inability to passage primary porcine luteal cells (PLCs) in vitro limit the luteal cell study. Therefore, developing an immortalized porcine luteal cell line is necessary for studying luteal cells activity and function in different diseases. In this study, primary PLCs were obtained from gilts at day 30 to day 50 of gestation and immortalized by human telomerase reverse transcriptase (hTERT). The porcine corpus luteal cell line (hTERT-PLCs) expressed hTERT gene steady, maintained high hTERT activity and normal karyotype. The phase contrast microscope and transmission electron microscope observation showed primary PLCs and hTERT-PLCs were polygonal and exhibited abundant mitochondria, smooth endoplasmic reticulum and lipid droplets. 3β hydroxysteroid dehydrogenase (3βHSD) and Oil-Red-O staining showed that hTERT-PLCs at passage 30 and 50 were similar to primary PLCs. The hTERT-PLCs expressed steroidogenesis-related proteins, enzymes and receptors, such as steroidogenic acute regulatory protein, P450 cholesterol side-chain cleavage, 3βHSD, 20αHSD, luteinizing hormone receptor, progesterone receptor, prolactin receptor, estrogen receptorα/β, as well as primary PLCs. Consequently, hTERT-PLCs could secret progesterone and exhibited similar responses to luteinizing hormone and prostaglandin F2α as primary PLCs. In addition, the hTERT-PLCs did not show neoplastic transformation or anchorage independent growth. In summary, we developed an immortalized porcine luteal cell line which maintained its originally morphological, biological and functional characteristics. Copyright © 2017 Elsevier Inc.

    The physicochemical characterization of polymer liposome complexes (PLCs) prepared with lipids of lactic acid bacteria and poly(N,N-dimethylaminoethyl methacrylate) covalently bound to cholesterol (CHO-PDMAEMA) was carried out in an integrated approach, including their stability upon preservation and incorporation into eukaryotic cells. PLCs were prepared with different polymer:lipid molar ratios (0, 0.05 and 0.10). Zeta potential, particle size distribution and polydispersity index were determined. The optimal polymer:lipid ratio and the stability of both bare liposomes and PLCs were evaluated at 37 °C and at different pHs, as well as after storage at 4 °C, -80 °C and freeze-drying in the presence or absence of trehalose 250 mM. Internalization of PLCs by eukaryotic cells was assessed to give a complete picture of the system. Incorporation of CHO-PDMAEMA onto bacterial lipids (ratio 0.05 and 0.10) led to stabilization at 37 °C and pH 7. A slight decrease of pH led to their strong destabilization. Bacteria PLCs showed to be more stable than lecithin (LEC) PLCs (used for comparison) upon preservation at 4 and -80 °C. The harmful nature of the preservation processes led to a strong decrease in the stability of PLCs, bacterial formulations being more stable than LEC PLCs. The addition of trehalose to the suspension of liposomes stabilized LEC PLC and did not have effect on bacterial PLCs. In vitro studies on Raw 264.7 and Caco-2/TC7 cells demonstrated an efficient incorporation of PLCs into the cells. Preparations with higher stability were the ones that showed a better cell-uptake. The nature of the lipid composition is determinant for the stability of PLCs. Lipids from lactic acid bacteria are composed of glycolipids and phospholipids like cardiolipin and phosphatidylglycerol. The presence of negatively charged lipids strongly improves the interaction with the positively charged CHO-PDMAEMA, thus stabilizing liposomes. In addition, glycolipids and phosphatidylglycerol act as intrinsic protectants of PLCs upon preservation. This particular lipid composition of lactic acid bacteria makes them natural formulations potentially useful as drug delivery systems. Copyright © 2014 Elsevier B.V. All rights reserved.

Many smart-grid subsystems are essentially cyber-physical energy systems (CPES): For instance, the power system process (i.e., the physical part) within a substation is monitored and controlled by a SCADA network with hosts running miscellaneous applications (i.e., the cyber part). To study the interactions between the cyber and physical components of a CPES, several co-simulation platforms have been proposed. However, the network simulators/emulators of these platforms do not include a detailed traffic model that takes into account the impactsmore » of the execution model of PLCs on traffic characteristics. As a result, network traces generated by co-simulation only reveal the impacts of the physical process on the contents of the traffic generated by SCADA hosts, whereas the distinction between PLCs and computing nodes (e.g., a hardened computer running a process visualization application) has been overlooked. To generate realistic network traces using co-simulation for the design and evaluation of applications relying on accurate traffic profiles, it is necessary to establish a traffic model for PLCs. In this work, we propose a parameterized model for PLCs that can be incorporated into existing co-simulation platforms. We focus on the DNP3 subsystem of slave PLCs, which automates the processing of packets from the DNP3 master. To validate our approach, we extract model parameters from both the configuration and network traces of real PLCs. Simulated network traces are generated and compared against those from PLCs. Our evaluation shows that our proposed model captures the essential traffic characteristics of DNP3 slave PLCs, which can be used to extend existing co-simulation platforms and gain further insights into the behaviors of CPES.« less

    Oestrogen is an important regulator in reproduction. To understand the role of oestrogen receptor 1 (ESR1) in Leydig cells, we investigated the expression of ESR1 in mouse Leydig cells during postnatal development and the effects of oestrogen on steroidogenesis and proliferation of progenitor Leydig cells (PLCs). In Leydig cells, the ESR1 expression was low at birth, increased until postnatal day 14 at which PLCs were predominant, and then decreased until adulthood. In foetal Leydig cells, ESR1 immunoreactivity increased from birth to postnatal day 14. These suggest that ESR1 is a potential biomarker of Leydig cell development. In PLCs, 17β-estradiol and the ESR1-selective agonist propylpyrazoletriol suppressed human chorionic gonadotropin (hCG)-induced progesterone production and steroidogenic gene expression. The ESR2-selective agonist diarylpropionitrile did not affect steroidogenesis. In PLCs from Esr1 knockout mice, hCG-stimulated steroidogenesis was not suppressed by 17β-estradiol, suggesting that oestrogen inhibits PLC steroidogenesis via ESR1. 17β-estradiol, propylpyrazoletriol, and diarylpropionitrile decreased bromodeoxyuridine uptake in PLCs in the neonatal mice. In cultured PLCs, 17β-estradiol, propylpyrazoletriol, and diarylpropionitrile reduced hCG-stimulated Ki67 and Pcna mRNA expression and the number of KI67-positive PLCs, suggesting that oestrogen inhibits PLC proliferation via both ESR1 and ESR2. In PLCs, ESR1 mediates the oestrogen-induced negative regulation of steroidogenesis and proliferation.

    My summer research experience at the Kennedy Space Center has been a truly rewarding one. As an electrical engineering student at the University of South Florida, I was blessed with a beneficial opportunity to gain valuable knowledge in my career, and also apply it through working at NASA. One of my inspirations in becoming an engineer is to work at NASA someday, and I was very excited and honored to have this opportunity. My goal in this internship was to strengthen my preparation in becoming an engineer by learning new material, acquiring skills by practicing what I learned, and discovering the expectations of engineering work at NASA. Through this summer research, I was able to learn new computer programs and perform various tasks that gave me experience and skills as an engineer. My primary job was to conduct work on the Constellation Test article, which is a simulation model of the Crew Launch Vehicle (CLV) tanking system. This is a prototype of a launch facility and an Ares I Vehicle, which God willing will transport astronauts to the moon. Construction of the CLV is in progress and a test launch is anticipated for 2010. Moreover, the Test Article serves as a demonstration too, training test bed, and may be expanded for new simulation of launch system elements, which could be applied to real life operations. The test article is operated and run by a Programmable Logic Controller (PLC), which is a digital computer that is used to control all forms of machinery such as those in manufacturing buildings and other industries. PLCs are different than other computers because of the physical protection they have against damaging environmental conditions that would destroy other computers. Also, PLCs are equipped with lots of input and output connections that allow extensive amounts of commands to be executed, which would normally require many computers to do. Therefore, PLCs are small, rugged, and extremely powerful tools that may continue to be employed at NASA. Furthermore, in order to conduct productive work on the Test Article, I needed to learn the computer program called RS Logics 5000.

  6. Developing a PLC-friendly state machine model: lessons learned

    2014-07-01

    Modern Programmable Logic Controllers (PLCs) have become an attractive platform for controlling real-time aspects of astronomical telescopes and instruments due to their increased versatility, performance and standardization. Likewise, vendor-neutral middleware technologies such as OPC Unified Architecture (OPC UA) have recently demonstrated that they can greatly facilitate the integration of these industrial platforms into the overall control system. Many practical questions arise, however, when building multi-tiered control systems that consist of PLCs for low level control, and conventional software and platforms for higher level control. How should the PLC software be structured, so that it can rely on well-known programming paradigms on the one hand, and be mapped to a well-organized OPC UA interface on the other hand? Which programming languages of the IEC 61131-3 standard closely match the problem domains of the abstraction levels within this structure? How can the recent additions to the standard (such as the support for namespaces and object-oriented extensions) facilitate a model based development approach? To what degree can our applications already take advantage of the more advanced parts of the OPC UA standard, such as the high expressiveness of the semantic modeling language that it defines, or the support for events, aggregation of data, automatic discovery, ... ? What are the timing and concurrency problems to be expected for the higher level tiers of the control system due to the cyclic execution of control and communication tasks by the PLCs? We try to answer these questions by demonstrating a semantic state machine model that can readily be implemented using IEC 61131 and OPC UA. One that does not aim to capture all possible states of a system, but rather one that attempts to organize the course-grained structure and behaviour of a system. In this paper we focus on the intricacies of this seemingly simple task, and on the lessons that we've learned during the development process of such a "PLC-friendly" state machine model.

    A general self-consistent field (SCF) for the mixture of polymer and low molecular weight (LMW) molecules has been derived by variation principle. Considering a Maier-Saupe type of interaction, the analytical expressions of the SCF for polymer liquid crystals (PLCs) and the mixture of PLCs and LMW liquid crystals are obtained, from which the phase behaviors of PLCs as well as the mixture are studied. The theoretical results are in agreement with experimental results by adjusting a parameter.

  8. The role of microtubules in contractile ring function.

    1992-05-01

    During cytokinesis, a cortical contractile ring forms around a cell, constricts to a stable tight neck and terminates in separation of the daughter cells. At first cleavage, Ilyanassa obsoleta embryos form two contractile rings simultaneously. The cleavage furrow (CF), in the animal hemisphere between the spindle poles, constricts to a stable tight neck and separates the daughter cells. The third polar lobe constriction (PLC-3), in the vegetal hemisphere below the spindle, constricts to a transient tight neck, but then relaxes, allowing the polar lobe cytoplasm to merge with one daughter cell. Eggs exposed to taxol, a drug that stabilizes microtubules, before the CF or the PLC-3 develop, fail to form CFs, but form stabilized tight PLCs. Eggs exposed to taxol at the time of PLC-3 formation develop varied numbers of constriction rings in their animal hemispheres and one PLC in their vegetal hemisphere, none of which relax. Eggs exposed to taxol after PLC-3 initiation form stabilized tight CFs and PLCs. At maximum constriction, control embryos display immunolocalization of nonextractable alpha-tubulin in their CFs, but not in their PLCs, and reveal, via electron microscopy, many microtubules extending through their CFs, but not through their PLCs. Embryos which form stabilized tightly constricted CFs and PLCs in the presence of taxol display immunolocalization of nonextractable alpha-tubulin in both constrictions and show many polymerized microtubules extending through both CFs and PLCs. These results suggest that the extension of microtubules through a tight contractile ring may be important for stabilizing that constriction and facilitating subsequent cytokinesis.

    2017-04-01

    The development of polymer-liposome complexes (PLCs), in particular for biomedical applications, has grown significantly in the last decades. The importance of these studies comes from the emerging need in finding intelligent controlled release systems, more predictable, effective and selective, for applications in several areas, such as treatment and/or diagnosis of cancer, neurological, dermatological, ophthalmic and orthopedic diseases, gene therapy, cosmetic treatments, and food engineering. This work reports the development and characterization of a pH sensitive system for controlled release based on PLCs. The selected hydrophilic polymer was poly(acrylic acid) (PAA) synthesized by atom transfer radical polymerization (ATRP) with a cholesterol (CHO) end-group to improve the anchoring of the polymer into the lipid bilayer. The polymer was incorporated into liposomes formulated from soybean lecithin and stearylamine, with different stearylamine/phospholipid and polymer/phospholipid ratios (5, 10 and 20%). The developed PLCs were characterized in terms of particle size, polydispersity, zeta potential, release profiles, and encapsulation efficiency. Cell viability studies were performed to assess the cytotoxic potential of PLCs. The results showed that the liposomal formulation with 5% of stearylamine and 10% of polymer positively contribute to the stabilization of the complexes. Afterwards, the carboxylic acid groups of the polymer present at the surface of the liposomes were crosslinked and the same parameters analyzed. The crosslinked complexes showed to be more stable at physiologic conditions. In addition, the release profiles at different pHs (2-12) revealed that the obtained complexes released all their content at acidic conditions. In summary, the main accomplishments of this work are: (i) innovative synthesis of cholesterol-poly(acrylic acid) (CHO-PAA) by ATRP; (ii) stabilization of the liposomal formulation by incorporation of stearylamine and CHO-PAA; (iii) new approach for CHO-PAA crosslinking, resulting in more stable PLCs at physiological conditions; (iv) destabilization of PLCs upon slight changes of pH, showing their pH sensitivity; and (v) the PLCs do not exhibit cellular toxicity.

    Background Phospholipase C (PLC) is one of the major lipid hydrolysing enzymes, implicated in lipid mediated signaling. PLCs have been found to play a significant role in abiotic stress triggered signaling and developmental processes in various plant species. Genome wide identification and expression analysis have been carried out for this gene family in Arabidopsis, yet not much has been accomplished in crop plant rice. Methodology/Principal Findings An exhaustive in-silico exploration of rice genome using various online databases and tools resulted in the identification of nine PLC encoding genes. Based on sequence, motif and phylogenetic analysis rice PLC gene family could be divided into phosphatidylinositol-specific PLCs (PI-PLCs) and phosphatidylcholine- PLCs (PC-PLC or NPC) classes with four and five members, respectively. A comparative analysis revealed that PLCs are conserved in Arabidopsis (dicots) and rice (monocot) at gene structure and protein level but they might have evolved through a separate evolutionary path. Transcript profiling using gene chip microarray and quantitative RT-PCR showed that most of the PLC members expressed significantly and differentially under abiotic stresses (salt, cold and drought) and during various developmental stages with condition/stage specific and overlapping expression. This finding suggested an important role of different rice PLC members in abiotic stress triggered signaling and plant development, which was also supported by the presence of relevant cis-regulatory elements in their promoters. Sub-cellular localization of few selected PLC members in Nicotiana benthamiana and onion epidermal cells has provided a clue about their site of action and functional behaviour. Conclusion/Significance The genome wide identification, structural and expression analysis and knowledge of sub-cellular localization of PLC gene family envisage the functional characterization of these genes in crop plants in near future.

    Nerve growth factor (NGF) has been reported to be involved in male reproductive physiology. However, few reports have described the activity of NGF during Leydig cell development. The objective of the present study was to examine the role of NGF during stem-Leydig-cell (SLC) regeneration. We investigated the effects of NGF on Leydig-cell (LC) regeneration by measuring mRNA levels in the adult rat testis after ethane dimethanesulfonate (EDS) treatment. Furthermore, we used the established organ culture model of rat seminiferous tubules to examine the regulation of NGF during SLC proliferation and differentiation using EdU staining, real-time PCR and western blotting. Progenitor Leydig cells (PLCs) and immature Leydig cells (ILCs) were also used to investigate the effects of NGF on LCs at different developmental stages. NGF mRNA levels changed significantly during Leydig-cell regeneration in vivo. In vitro, NGF significantly promoted the proliferation of stem Leydig cells and also induced steroidogenic enzyme gene expression and 3β-HSD protein expression. The data from PLCs and ILCs showed that NGF could increase Cyclin D1 and Hsd 17b3 mRNA levels in PLCs and Cyclin D1 mRNA levels in ILCs. These results indicate that NGF may play an important role during LC regeneration by regulating the proliferation and differentiation of LCs at different developmental stages, from SLCs to PLCs and from PLCs to ILCs. The discovery of this effect of NGF on Leydig cells will provide useful information for developing new potential therapies for PADAM (Partial Androgen Deficiency in the Aging Male).

    Phospholipase Cs (PLCs) contribute importantly to the virulence and pathogenicity of several bacteria. It has been reported in previous studies that mutations in the four predicted plc genes of Mycobacterium tuberculosis inhibit the growth of these bacteria during the late phase of infection in mice. These enzymes have not yet been fully characterised, mainly because they are not easy to produce in large quantities. With a view to elucidating the role of all Mycobacterium tuberculosis phospholipase Cs (PLC-A, PLC-B, PLC-C and PLC-D), a large amount of active, soluble recombinant PLCs, were expressed and purified using Mycobacterium smegmatis as expression system. These enzymes showed different pH activity profiles. PLC-C was found to be the most active of the four recombinant PLCs under acidic conditions. All the enzymes tested induced cytotoxic effects on mouse macrophage RAW 264.7 cell lines, via direct or indirect enzymatic hydrolysis of cell membrane phospholipids. These results open new prospects for characterising biochemical and structural features of Mycobacterium tuberculosis PLCs, which might lead to the identification of novel anti-tuberculosis drug targets. All mycobacterial phospholipase Cs can now be studied in order to determine their role in the virulence and pathogenicity of bacteria of this kind. 2010 Elsevier B.V. All rights reserved.

    The power line communications (PLCs) can count on existing electrical connections reaching each corner in the locations where such applications are required, so signal transmission over power lines is nowadays gaining more and more interest for applications like internet. The research of characteristics of the low voltage power line is the fundamental and importance task. This work presents a device to test the characteristics of the low voltage power line. The low voltage power line channel characteristics overground and the channel characteristics underground were tested in using this device. Experiments show that, the characteristics are different between the PLCs channel underground coal mine and the PLC channel overground. Different technology should be adopted to structure the PLCs channel model underground coal mine and transmit high speed digital signal. But how to use the technology better to the high-speed digital communication under coal mine is worth of further studying.

    Project-based learning is a learning method that uses project activities as the core of learning and requires student creativity in completing the project. The aims of this study is to investigate the influence of project-based learning methods on students with a high level of creativity in learning the Programmable Logic Controller (PLC). This study used experimental methods with experimental class and control class consisting of 24 students, with 12 students of high creativity and 12 students of low creativity. The application of project-based learning methods into the PLC courses combined with the level of student creativity enables the students to be directly involved in the work of the PLC project which gives them experience in utilizing PLCs for the benefit of the industry. Therefore, it’s concluded that project-based learning method is one of the superior learning methods to apply on highly creative students to PLC courses. This method can be used as an effort to improve student learning outcomes and student creativity as well as to educate prospective teachers to become reliable educators in theory and practice which will be tasked to create qualified human resources candidates in order to meet future industry needs.

    To compare outcomes in patients receiving polytetrafluoroethylene (PTFE) and polyurethane (PL) covered stents (CS) after coronary artery perforation (CAP). The prognosis of CAP has improved with the advent of CSs. Information is scarce about the outcomes of new-generation CSs. Sixty-one patients were treated with CSs in a 5-years period (age = 77 ± 8.75% males). Procedural and clinical data were retrospectively collected. The primary endpoint was procedural success. Secondary endpoints included death and major adverse cardiac events (MACE) defined as a composite of death, myocardial infarction, target vessel, and lesion revascularization and need for surgical repair). Twenty-two (36%) received PL-CSs and 39 (65%) PTFE-CSs. There were no differences in procedural success (86% vs 69%, P = 0.216). Time to deliver was shorter with PL-CS despite larger length of stents (8[11] vs 15[16] min, P = 0.001; 20[5] vs 16[3] mm, P < 0.001). This group had lower rate of pericardial effusion and cardiac arrest (41% vs 72%, P = 0.028; 5% vs 26%, P = 0.045). At 1-year follow-up, MACE rates were similar (58% vs 56%, P = 1.000) with atrend toward TVR in the PL-CS arm (21% vs 5%, P = 0.083). No differences were found in mortality (26% vs 41%, P = 0.385). Each group had 1 stent thrombosis and in-stent restenosis trended higher in the PL-CS group (12% vs 3%, P = 0.223). Time to deliver was shorter with the PL-CS and resulted in lower rate of pericardial effusion and cardiac arrest. However, there were no significant differences in procedural success and 1-year follow-up MACE in patients treated with PL-CS or PTFE-CS. © 2018, Wiley Periodicals, Inc.

    Most automated industrial processes use Distributed Control Systems (DCSs) or Programmable Logic Controllers (PLCs) for automated control. PLCs tend to be more common as they have much of the functionality of DCSs, although they are generally cheaper to install and maintain. PLCs in conjunction with a human machine interface form the basis of Supervisory Control And Data Acquisition (SCADA) systems, combined with communication infrastructure and Remote Terminal Units (RTUs). RTU's basically convert different sensor measurands in to digital data that is sent back to the PLC or supervisory system. Optical fibre sensors are becoming more common in industrial processes because of their many advantageous properties. Being small, lightweight, highly sensitive, and immune to electromagnetic interference, means they are an ideal solution for a variety of diverse sensing applications. Here, we have developed a PLC Optical Fibre Sensor Interface Module (OFSIM), in which an optical fibre is connected directly to the OFSIM located next to the PLC. The embedded fibre Bragg grating sensors, are highly sensitive and can detect a number of different measurands such as temperature, pressure and strain without the need for a power supply.

Monitoring software is developed using VB6.0 for data input/output, flow control and online parameters setting. As a result, all functions are fulfilled with robust performance. It is concluded from results that one PC can monitor several PLCs using RS-485 communication.

  4. D0 General Support: The Use of Programmable Logic Controllers (PLCS) at D0

    Hance, R.; /Fermilab

    With the exception of control of heating, ventilation, and air conditioning (HVAC) ventilation fans, and their shutdown in the case of smoke in the ducts, all implementations of Programmable Logic Controllers (PLCs) in Dzero have been made within the fundamental premise that no uncertified PLC apparatus shall be entrusted with the safety of equipment or personnel. Thus although PLCs are used to control and monitor all manner of intricate equipment, simple hardware interlocks and relief devices provide basic protection against component failure, control failure, or inappropriate control operation. Nevertheless, this report includes two observations as follows: (1) It may bemore » prudent to reconfigure the link between the Pyrotronics system and the HVAC system such that the Pyrotronics system provides interlocks to the ventilation fans instead of control inputs to the uncertified HVAC PLCs. Although the Pyrotronics system is certified and maintained to life safety standards, the HVAC system is not. A hardware or software failure of the HVAC system probably should not be allowed to result in the situation where the ventilation fans in a smoke filled duct continue to operate. Dan Markley is investigating this matter. (2) It may also be prudent to examine the network security of those systems connected to the Fermilab WAN (HVAC, Cryo, and Solenoid Controls). Even though the impact of a successful hack might only be to operations, it might nevertheless be disruptive and could be expensive. The risks should perhaps be analyzed. One of the most attractive features of these systems, from a user's viewpoint, is their unlimited networking. The unlimited networking that makes the systems so convenient to legitimate access also makes them vulnerable to illegitimate access.« less

    Using language appropriately and effectively in social contexts requires pragmatic language competencies (PLCs). Increasingly, deficits in PLCs are linked to child and adolescent disorders, including autism spectrum, externalizing, and internalizing disorders. As the role of PLCs expands in diagnosis and treatment of developmental psychopathology, psychologists and educators will need to appraise and select clinical and research PLC instruments for use in assessments and/or studies. To assist in this appraisal, 24 PLC instruments, containing 1,082 items, are assessed by addressing four questions: (1) Can PLC domains targeted by assessment items be reliably identified?, (2) What are the core PLC domains that emerge across the 24 instruments?, (3) Do PLC questionnaires and tests assess similar PLC domains?, and (4) Do the instruments achieve content, structural, diagnostic, and ecological validity? Results indicate that test and questionnaire items can be reliably categorized into PLC domains, that PLC domains featured in questionnaires and tests significantly differ, and that PLC instruments need empirical confirmation of their dimensional structure, content validity across all developmental age bands, and ecological validity. Progress in building a better evidence base for PLC assessments should be a priority in future research.

    Mycobacterium tuberculosis, the agent of human tuberculosis has developed different virulence mechanisms and virulence-associated tools during its evolution to survive and multiply inside the host. Based on previous reports and by analogy with other bacteria, phospholipases C (PLC) of M. tuberculosis were thought to be among these tools. To get deeper insights into the function of PLCs, we investigated their putative involvement in the intracellular lifestyle of M. tuberculosis, with emphasis on phagosomal rupture and virulence, thereby re-visiting a research theme of longstanding interest. Through the construction and use of an M. tuberculosis H37Rv PLC-null mutant (ΔPLC) and control strains, we found that PLCs of M. tuberculosis were not required for induction of phagosomal rupture and only showed marginal, if any, impact on virulence of M. tuberculosis in the cellular and mouse infection models used in this study. In contrast, we found that PLC-encoding genes were strongly upregulated under phosphate starvation and that PLC-proficient M. tuberculosis strains survived better than ΔPLC mutants under conditions where phosphatidylcholine served as sole phosphate source, opening new perspectives for studies on the role of PLCs in the lifecycle of M. tuberculosis.

    Despite the introduction of high-technology methods of detection and diagnosis, screening of primary liver cancer (PLC) remains imperfect. To diagnosis PLC earlier, Surface-enhanced Raman spectroscopy (SERS) coupled with cellulose-acetate membrane electrophoresis were introduced to separate human serum albumin and SERS spectra. Three groups (15 normal persons' samples, 17 hepatitis/cirrhosis samples, 15 cases of PLC) of serum albumin were tested. Silver colloid was used to obtain SERS spectra of human serum albumin. Principal component analysis (PCA) and linear discriminant analysis (LDA) were also employed for statistical analysis. The mean Raman spectra of three groups and the difference spectra of any two suggested that the albumin has changed in liver patients. Compared to normal groups, some Raman peaks have shifted or even disappeared in hepatitis/cirrhosis and PLCs groups. The sensitivity and specificity between PLCs and normal groups is 80% and 93.3%. Among hepatitis/cirrhosis and normal groups, the sensitivity is 88.2% and specificity is also 93.3%. Besides, the sensitivity and specificity between PLCs and hepatitis/cirrhosis groups is 86.7% and 76.5%. All the above data and results indicated that early screening of PLC is potential by SERS in different stages of liver disease before cancer occurs.

    The Ceratocystis genus harbors a large number of phytopathogenic fungi that cause xylem parenchyma degradation and vascular destruction on a broad range of economically important plants. Ceratocystis cacaofunesta is a necrotrophic fungus responsible for lethal wilt disease in cacao. The aim of this work is to analyze the genome of C. cacaofunesta through a comparative approach with genomes of other Sordariomycetes in order to better understand the molecular basis of pathogenicity in the Ceratocystis genus. We present an analysis of the C. cacaofunesta genome focusing on secreted proteins that might constitute pathogenicity factors. Comparative genome analyses among five Ceratocystidaceae species and 23 other Sordariomycetes fungi showed a strong reduction in gene content of the Ceratocystis genus. However, some gene families displayed a remarkable expansion, in particular, the Phosphatidylinositol specific phospholipases-C (PI-PLC) family. Also, evolutionary rate calculations suggest that the evolution process of this family was guided by positive selection. Interestingly, among the 82 PI-PLCs genes identified in the C. cacaofunesta genome, 70 genes encoding extracellular PI-PLCs are grouped in eight small scaffolds surrounded by transposon fragments and scars that could be involved in the rapid evolution of the PI-PLC family. Experimental secretome using LC-MS/MS validated 24% (86 proteins) of the total predicted secretome (342 proteins), including four PI-PLCs and other important pathogenicity factors. Analysis of the Ceratocystis cacaofunesta genome provides evidence that PI-PLCs may play a role in pathogenicity. Subsequent functional studies will be aimed at evaluating this hypothesis. The observed genetic arsenals, together with the analysis of the PI-PLC family shown in this work, reveal significant differences in the Ceratocystis genome compared to the classical vascular fungi, Verticillium and Fusarium. Altogether, our analyses provide new insights into the evolution and the molecular basis of plant pathogenicity.

    Total body photography (TBP) can facilitate identification of new and changing lesions. By confirming that particular nevi are stable, TBP may reduce nevus biopsies. We sought to determine the number and rate of nevus biopsies before and after TBP, and the factors associated with increased biopsy rate during monitoring by TBP. We reviewed records of all patients in 2 pigmented lesion clinics (PLCs) who received TBP and had 2 or more follow-up visits over a period of 2 years or longer. Before PLCs and TBP, the mean number of nevus biopsies per patient was 5.92 (589 patients) at a mean rate of 1.62 per year (160 patients). After TBP in PLCs, the same patients averaged 1.56 biopsies at a mean rate of 0.34 per year (P < 2 × 10(-16)). The entire cohort (926 patients) averaged similarly low post-TBP biopsy rates of less than 0.2 per year and per visit. Biopsy rates after TBP were positively correlated with decreased age, male gender, and family history of melanoma, but not nevus number. Some information was not available for some patients. Patients at risk for melanoma experienced a 3.8-fold reduction in nevus biopsies after TBP. Younger male patients with family history of melanoma had higher biopsy rates after TBP.

    Postnatal Leydig cell development in rat involves an initial phase of proliferation of progenitor Leydig cells (PLCs) and subsequent differentiation of these cells into immature Leydig cells (ILCs) and adult Leydig cells (ALCs). With an objective to identify the molecular changes associated with Leydig cell differentiation, the mRNA population in PLCs and ILCs were analyzed by the technique of differential display reverse transcription polymerase chain reaction (DD-RT-PCR). Results revealed differential expression of several transcripts in PLCs and ILCs. Of the several differentially expressed transcripts, the expression of transcripts corresponding to collagen IV alpha6 (Col IV alpha6) and ribosomal protein L 41 (RpL41) decreased during the differentiation of PLC to ILC. Also there was an increase in the expression of transcripts encoding enzymes such as microsomal glutathione-S-transferase (mGST 1) and 7-dehydrocholesterol reductase (7-DHCR) during this process. While Col IV alpha6 and RpL41 are known to be involved in cellular proliferation, mGST 1 and 7-DHCR are essential for normal Leydig cell steroidogenesis. A detailed study on 7-DHCR expression in Leydig cells revealed that this enzyme plays a crucial role in steroidogenesis. Interestingly expression of this enzyme is not under acute regulation by Luteinizing hormone (LH). Copyright 2004 Elsevier Ireland Ltd.

  13. Detecting Payload Attacks on Programmable Logic Controllers (PLCs)

    DOE Office of Scientific and Technical Information (OSTI.GOV)

    Yang, Huan

    Programmable logic controllers (PLCs) play critical roles in industrial control systems (ICS). Providing hardware peripherals and firmware support for control programs (i.e., a PLC’s “payload”) written in languages such as ladder logic, PLCs directly receive sensor readings and control ICS physical processes. An attacker with access to PLC development software (e.g., by compromising an engineering workstation) can modify the payload program and cause severe physical damages to the ICS. To protect critical ICS infrastructure, we propose to model runtime behaviors of legitimate PLC payload program and use runtime behavior monitoring in PLC firmware to detect payload attacks. By monitoring themore » I/O access patterns, network access patterns, as well as payload program timing characteristics, our proposed firmware-level detection mechanism can detect abnormal runtime behaviors of malicious PLC payload. Using our proof-of-concept implementation, we evaluate the memory and execution time overhead of implementing our proposed method and find that it is feasible to incorporate our method into existing PLC firmware. In addition, our evaluation results show that a wide variety of payload attacks can be effectively detected by our proposed approach. The proposed firmware-level payload attack detection scheme complements existing bumpin- the-wire solutions (e.g., external temporal-logic-based model checkers) in that it can detect payload attacks that violate realtime requirements of ICS operations and does not require any additional apparatus.« less

    Energy is an important factor in today's industrial environment. Pump systems account for about 20% of the total industrial electrical energy consumption. Several studies show that with proper monitoring, control and maintenance, the efficiency of pump systems can be increased. Controlling pump systems with intelligent systems can help to reduce a pump's energy consumption by up to one third of its original consumption. The research in this paper was carried out in the scope of a research project which involves modelling and simulation of pump systems. This paper focuses on the future implementation of modelling capabilities in PLCs (programmable logic controllers). The whole project aims to use a pump itself as the sensor rather than introducing external sensors into the system, which would increase the cost considerably. One promising approach for an economic and robust industrial implementation of this intelligence is the use of PLCs. PLCs can be simulated in multiple ways; in this project, Codesys was chosen for several reasons which are explained in this paper. The first part of this paper explains the modelling of a pump itself, the process load of the asynchronous motor with a control system, and the simulation possibilities of the motor in Codesys. The second part describes the simulation and testing of a system realized. The third part elaborates the Codesys system structure and interfacing of the system with external files. The final part consists of comparing the result with an earlier Matlab/SIMULINK model and original test data.

    Programmable logic controllers (PLCs) have very limited diagnostic and no prognostic capabilities, while current smart sensor designs do not have the capability to communicate over Fieldbus networks. The aim is to interface smart sensors with PLCs so that health and status information, such as failure mode identification and measurement tolerance, can be communicated via an industrial Fieldbus such as ControlNet. The SNE Industrial Fieldbus Interface (SIFI) is an embedded device that acts as a communication module in a networked smart sensor. The purpose is to enable a smart sensor to communicate health and status information to other devices, such as PLCs, via an industrial Fieldbus networking protocol. The SNE (Smart Network Element) is attached to a commercial off-the-shelf Any bus-S interface module through the SIFI. Numerous Anybus-S modules are available, each one designed to interface with a specific Fieldbus. Development of the SIFI focused on communications using the ControlNet protocol, but any of the Anybus-S modules can be used. The SIFI communicates with the Any-bus module via a data buffer and mailbox system on the Anybus module, and supplies power to the module. The Anybus module transmits and receives data on the Fieldbus using the proper protocol. The SIFI is intended to be connected to other existing SNE modules in order to monitor the health and status of a transducer. The SIFI can also monitor aspects of its own health using an onboard watchdog timer and voltage monitors. The SIFI also has the hardware to drive a touchscreen LCD (liquid crystal display) unit for manual configuration and status monitoring.

  17. Performance of portland limestone cements: Cements designed to be more sustainable that include up to 15% limestone addition

    NASA Astrophysics Data System (ADS)

    Barrett, Timothy J.

    In 2009, ASTM and AASHTO permitted the use of up to 5% interground limestone in ordinary portland cement (OPC) as a part of a change to ASTM C150/AASHTO M85. When this work was initiated a new proposal was being discussed that would enable up to 15% interground limestone cement to be considered in ASTM C595/AASHTO M234. This work served to provide rapid feedback to the state department of transportation and concrete industry for use in discussions regarding these specifications. Since the time this work was initiated, ASTM C595/AASHTO M234 was passed (2012c) and PLCs are now able to be specified, however they are still not widely used. The proposal for increasing the volume of limestone that would be permitted to be interground in cement is designed to enable more sustainable construction, which may significantly reduce the CO2 that is embodied in the built infrastructure while also extending the life of cement quarries. Research regarding the performance of cements with interground limestone has been conducted by the cement industry since these cements became widely used in Europe over three decades ago, however this work focuses on North American Portland Limestone Cements (PLCs) which are specifically designed to achieve similar performance as the OPCs they replace.This thesis presents a two-phase study in which the potential for application of cements containing limestone was assessed. The first phase of this study utilized a fundamental approach to determine whether cement with up to 15% of interground or blended limestone can be used as a direct substitute to ordinary portland cement. The second phase of the study assessed the concern of early age shrinkage and cracking potential when using PLCs, as these cements are typically ground finer than their OPC counterparts. For the first phase of the study, three commercially produced PLCs were obtained and compared to three commercially produced OPCs made from the same clinker. An additional cement was tested where the limestone was blended (i.e., not interground) as needed, enabling variation of the size of the limestone particles. In addition, one of the commercially produced OPCs and PLCs were used with fly ash. A series of standardized tests were run to assess the physical effects of intergrinding limestone in portland cement, the effect of limestone presence and method of inclusion on the hydration reaction, and the associated mechanical and transport properties of concretes made with these limestone cements. The second phase of the study used a commercially produced OPC, a PLC, and a PLC-slag all made from the same parent clinker to quantify the early age shrinkage and cracking potential. The study presents a series of tests that quantify the fundamental origins of shrinkage in cementitious materials to elucidate the differences between PLC and OPC. The bulk shrinkage of these systems is then quantified under free and restrained conditions to provide an assessment of the susceptibility for cracking in portland limestone cements. The results of the first phase of this thesis showed that in general the PLC and OPC systems have similar hydration, set, and mechanical performance. Transport properties in this study show behavior that is +/- 30% of the conventional OPC system depending on the system. Literature has shown similar freeze-thaw resistance when these materials are used in properly air entrained mixtures, and the results for PLC systems with fly ash show added performance. Based on these results it appears that PLC that meets ASTM C595/AASHTO M234 should be able to be used interchangeably with OPC, while it should also be noted that the investigation of the influence of salts and sulfates on PLCs is still ongoing and should be monitored. The results of the second phase of this thesis showed that while the PLCs are finer, this comes primarily by reducing the very large particles (clinker particles greater than 30 microns) using advanced separator technology and increasing the number of very fine limestone particles. This results in the cements tested having similar autogenous shrinkage development in the PLC systems compared to the OPC, with slightly less shrinkage in the PLC-slag system. The stress that develops when this shrinkage is restrained is very similar in comparing the OPC, PLC and PLC-slag systems and the PLC mixture tends to crack at a similar or slightly earlier times.

    Ca 2+ is an important second messenger, and it is involved in many cellular processes such as cell death and proliferation. The rise in intracellular Ca 2+ levels can be due to the generation of inositol 1,4,5-trisphosphate (InsP 3 ), which is a product of phosphatidylinositol 4,5-bisphosphate (PIP 2 ) hydrolysis by phospholipases C (PLCs), that leads to Ca 2+ release from endoplasmic reticulum by InsP 3 receptors (InsP 3 R). Ca 2+ signaling patterns can vary in different regions of the cell and increases in nuclear Ca 2+ levels have specific biological effects that differ from those of Ca 2+ increase in the cytoplasm. There are PLCs in the cytoplasm and nucleus, but little is known about the functions of nuclear PLCs. This work aimed to characterize phenotypically the human PLCδ4 (hPLCδ4) in mesenchymal stem cells. This nuclear isoform of PLC is present in different cell types and has a possible role in proliferative processes. In this work, hPLCδ4 was found to be mainly nuclear in human adipose-derived mesenchymal stem cells (hASC). PLCδ4 knockdown demonstrated that it is essential for hASC proliferation, without inducing cell death. An increase of cells in G1, and a reduction of cells on interphase and G2/M in knockdown cells were seen. Furthermore, PLCδ4 knockdown increased the percentage of senescent cells, p16 INK4A+ and p21 Cip1 mRNAs expression, which could explain the impaired cell proliferation. The results show that hPLCδ4 is in involved in cellular proliferation and senescence in hASC. Copyright © 2018 Elsevier Inc. All rights reserved.

    The postoperative course of preterm babies undergoing surgical closure of a patent ductus arteriosus (PDA) is often complicated by postligation cardiac syndrome (PLCS). Despite targeted milrinone prophylaxis, some infants continue to experience postoperative respiratory deterioration. Our objective is to describe the immediate postoperative course and identify risk factors for respiratory instability when preterm infants undergoing PDA ligation are managed with targeted milrinone treatment. A retrospective review of a cohort of infants undergoing PDA ligation between January, 2010 and August, 2013 was conducted. All infants had a targeted neonatal echocardiogram performed 1 hour after surgery. Infants received prophylactic milrinone treatment if the left ventricular output was <200 mL/kg/min. The primary outcome measure was the development of respiratory instability within 24 hours of surgery. Multivariable logistic regression was performed to identify predictors of respiratory instability. Eighty-six infants with a median gestational age of 25 weeks (interquartile range [IQR], 24-26) and a birth weight of 740 g (IQR, 640-853) were included in this study. Forty-nine (57.0%) received milrinone prophylaxis. There were 44 (51.2%) infants who developed oxygenation or ventilation failure, and 7 (8.1%) neonates developed PLCS. Infants with longer isovolumic relaxation time (IVRT ≥30 milliseconds) were more likely to develop either oxygenation or ventilation failure. Although the incidence of PLCS has declined after the introduction of targeted milrinone prophylaxis, many preterm infants continue to develop respiratory instability after surgical ligation. In this population, diastolic dysfunction manifested by prolonged IVRT could be associated with an adverse postoperative respiratory course.

    The thermal vacuum facilities located at the Goddard Space Flight Center (GSFC) have supported both manned and unmanned space flight since the 1960s. Of the eleven facilities, currently ten of the systems are scheduled for refurbishment or replacement as part of a five-year implementation. Expected return on investment includes the reduction in test schedules, improvements in safety of facility operations, and reduction in the personnel support required for a test. Additionally, GSFC will become a global resource renowned for expertise in thermal engineering, mechanical engineering, and for the automation of thermal vacuum facilities and tests. Automation of the thermal vacuum facilities includes the utilization of Programmable Logic Controllers (PLCs), the use of Supervisory Control and Data Acquisition (SCADA) systems, and the development of a centralized Test Data Management System. These components allow the computer control and automation of mechanical components such as valves and pumps. The project of refurbishment and automation began in 1996 and has resulted in complete computer control of one facility (Facility 281), and the integration of electronically controlled devices and PLCs in multiple others.

  6. Competition between Anion Binding and Dimerization Modulates Staphylococcus aureus Phosphatidylinositol-specific Phospholipase C Enzymatic Activity*

    2012-01-01

    Staphylococcus aureus phosphatidylinositol-specific phospholipase C (PI-PLC) is a secreted virulence factor for this pathogenic bacterium. A novel crystal structure shows that this PI-PLC can form a dimer via helix B, a structural feature present in all secreted, bacterial PI-PLCs that is important for membrane binding. Despite the small size of this interface, it is critical for optimal enzyme activity. Kinetic evidence, increased enzyme specific activity with increasing enzyme concentration, supports a mechanism where the PI-PLC dimerization is enhanced in membranes containing phosphatidylcholine (PC). Mutagenesis of key residues confirm that the zwitterionic phospholipid acts not by specific binding to the protein, but rather by reducing anionic lipid interactions with a cationic pocket on the surface of the S. aureus enzyme that stabilizes monomeric protein. Despite its structural and sequence similarity to PI-PLCs from other Gram-positive pathogenic bacteria, S. aureus PI-PLC appears to have a unique mechanism where enzyme activity is modulated by competition between binding of soluble anions or anionic lipids to the cationic sensor and transient dimerization on the membrane.

  7. Investigating the Interactions, Beliefs, and Practices of Teacher-Coach Teams in a STEM After-School Setting

    NASA Astrophysics Data System (ADS)

    Swanson Hoyle, Kylie Jayne

    After-school programs, such as a STEM Career Club, can promote student interest, engagement, and awareness of STEM majors and fields, as well as encourage teachers to become more knowledgeable and competent in STEM areas. In this dissertation study, two schools were selected from a larger NSF-funded project to participate in this study. Teacher- Coaches (T-Coaches) from two rural middle schools in the southeastern United States (U.S.) participated in teacher professional development (TPD) sessions and Professional Learning Community (PLC) meetings to prepare them to lead an after-school STEM Club. The Community of Practice (CoP) framework and Social Cognitive Theory are employed to investigate underlying factors that contribute to teacher interactions and preparations, and differing STEM program outcomes. Data from the Dimensions of Success (DoS) observation tool, the teacher belief interview (TBI), T-Coach participation and attendance at TPD, attendance and audio recordings from PLC meetings, and T-Coach card sorts were analyzed over approximately 6 meetings for 5 months. Findings are presented in two chapters. In Chapter Four, a comparative case study of the interactions of the teachers at two participating middle schools is analyzed. Results indicate that for each case, the club's T-Coaches interacted positively to prepare for club meetings and have a well-functioning CoP within their PLC. The first case (Northern Middle School) interacted in ways that aligned with the CoP framework (enterprise and repertoire), which led them to achieve, on average, desirable ratings on 7 of the 12 DoS dimensions. However, the other case (Southern Middle School), the T-Coaches interacted in ways that demonstrated more equal levels of enterprise, mutuality, and repertoire; this PLC had higher DoS ratings during the STEM Clubs in all dimensions (11/12 met desirable ratings). These findings suggest that high levels of all of the social learning characteristics within PLCs can support more exemplary STEM Club implementation. In Chapter Five, results from the two schools of teachers' beliefs and practices indicate that for STEM program success, the whole of the team is better than the sum of its parts. Since individuals' values on each team aligned with different DoS dimensions, it was more likely that each dimension would be represented during STEM Clubs. Findings suggest that it was necessary for two T-Coaches who valued a certain dimension to ensure a DoS dimension would be met on the DoS rating. However, it was not sufficient that T-Coaches only valued a certain dimension. The dimension was not met if the T-Coaches did not have the training and preparation to meaningfully act on their beliefs. Informed by factors from Bandura's Social Cognitive Theory, these T-Coaches carried out different behaviors at the STEM Clubs depending on their personal beliefs and values, and the environment. Five TPD participation scenarios, ranging from full to no TPD preparation, identified from the findings seemed to predict the quality of the STEM Club, based on DoS scores. The following conclusions can be drawn: 1) Professional learning community meetings aided in the development of T-Coaches' community of practice and preparation for STEM clubs; 2) A CoP with high levels of all of the social learning characteristics (enterprise, mutuality, and repertoire) led to more desirable club outcomes than a team with lower levels in any of these areas; 3) At least two people who have developed the content knowledge and relevant skills and who value club success were needed at club meetings to ensure STEM Club success; 4) Teacher-Coaches became more prepared to lead successful STEM Clubs through engaged attendance at TPD and PLC meetings; 5) Interdisciplinary teacher teams, including non-STEM teachers, can successfully lead STEM clubs if the individuals are able to learn the content/skills.

    2015-04-01

    The EC LIFE+2010 DIAPASON Project (Desert dust Impact on Air quality through model-Predictions and Advanced Sensors ObservatioNs, www.diapason-life.eu) intends to contribute new methodologies to assess the role of aerosol advections of Saharan dust to the local PM loads recorded in Europe. To this goal, automated Polarization Lidar-Ceilometers (PLCs) were prototyped within DIAPASON to certify the presence of Saharan dust plumes and support evaluating their mass loadings in the lowermost atmosphere. The whole process also involves operational dust forecasts, as well as satellite and in-situ observations. Demonstration of the Project is implemented in the pilot region of Rome (Central Italy) where three networked DIAPASON PLCs started, in October 2013 a year-round, 24h/day monitoring of the altitude-resolved aerosol backscatter and depolarization profiles. Two intensive observational periods (IOPs) involving chemical analysis and detailed physical characterization of aerosol samples have also been carried out in this year-long campaign, namely in Fall 2013 and Spring 2014. These allowed for an extensive interpretation of the PLC observations, highlighting important synergies between the PLC and the in situ data. The presentation will address capabilities of the employed PLCs, observations agreement with model forecasts of dust advections, retrievals of aerosol properties and methodologies developed to detect Saharan advections and to evaluate the relevant mass contribution to PM10. This latter task is intended to provide suggestions on possible improvements to the current EC Guidelines (2011) on this matter. In fact, specific Guidelines are delivered by the European Commission to provide the Member States a common method to asses the Saharan dust contribution to the currently legislated PM-related Air Quality metrics. The DIAPASON experience shows that improvements can be proposed to make the current EC Methodology more robust and flexible. The methodology DIAPASON recommends has been designed and validated taking advantage of the PLC observations and highlights the benefits of the operational use of such systems in routine Air Quality applications. Concurrently, PLC activities are contributing to the COST Action "TOPROF", an European effort aiming at the setup and operational use of Lidar-Ceilometers networks for meteorological and safety purposes.

    The purpose of this study was to explore the clinicopathological features and survival outcome of pleomorphic lobular carcinoma (PLC) of breast, we identified 131 PLC patients and 460,109 invasive ductal carcinoma (IDC) patients in the Surveillance, Epidemiology, and End Result (SEER) database. PLCs presented with increased lymph node involvement, older age, higher AJCC stage and grade, and lower median survival months (PLC 84 ± 51.03 vs. IDC 105.2 ± 64.39 P < 0.01). Compared to IDC patients, PLC patients were more inclined to be treated with mastectomy. In univariate analysis, PLC patients showed a worse disease-specific survival (DSS) than that of IDC patients (hazard ratio = 0.691, 95% confidence interval 0.534-0.893, P < 0.01). In multivariate analysis, we took into account other prognostic factors and found that the histology types were no longer an independent prognostic factor (P = 0.120). DSS have no difference between matched IDC and PLC groups (P = 0.615). This result may be due to PLCs presenting higher tumor stage, higher tumor grade, and higher rate of LN metastasis than IDCs. Our conclusion is that PLC and IDC have many different characteristics, but there is not enough difference on the DSS. © 2017 The Authors. Cancer Medicine published by John Wiley & Sons Ltd.

    Generally, cohorts or learning communities enrich higher learning in students. Learning communities consist of conventionally separate groups of students that meet together with common academic purposes and goals. Types of learning communities include paired courses with concurrent student enrollment, living-learning communities, and faculty learning communities. This article discusses a learning community of 21 students that I created with a colleague in the English department. The community encompasses two general education courses: an algebra-based physics course entitled "Intro to Physics" and a literature course entitled "Science Fiction, Science Fact." Students must enroll in both of these courses during the same semester. Additionally, I highlight advantages to linking these courses through surveying the assignments and course materials that we used in our learning community. Figure 1 shows the topics that are covered in both physics and literature courses.

  13. Cultural patterns in children's learning through keen observation and participation in their communities.

    PubMed

    Correa-Chávez, Maricela; Roberts, Amy L D; Pérez, Margarita Martínez

    2011-01-01

    This chapter examines children's learning through careful attention and participation in the ongoing activities of their community. This form of learning, which has been called learning through Intent Community Participation, seems to be especially common in Mesoamerican Indigenous communities. In these communities, children are integrated into the everyday work and lives of adults and their learning may not be the central focus. We contrast this pattern with that of middle-class European American communities where children are segregated from the primary adult functions of the community. In middle-class communities and schools, children are often encouraged to engage in abstract lessons where their attention is explicitly directed to specific events. In contrast, learning through keen attention and observation may rely on learning through attention to instructions not specifically directed to the learner. Studies demonstrate Mesoamerican Indigenous children's ability to learn through simultaneous and open attention to overheard or observed activities. This form of learning is supported through multiple modalities of communication and interaction. Motivation to learn stems from the learner's inclusion into the major activities and goals of the community. Implications of research and future directions for the study of learning through keen observation are discussed.

    Lesson Study for Learning Community is one of lecturer profession building system through collaborative and continuous learning study based on the principles of openness, collegiality, and mutual learning to build learning community in order to form professional learning community. To achieve the above, we need a strategy and learning method with specific subscription technique. This paper provides a description of how the quality of learning in the field of science can be improved by implementing strategies and methods accordingly, namely by applying lesson study for learning community optimally. Initially this research was focused on the study of instructional techniques. Learning method used is learning model Contextual teaching and Learning (CTL) and model of Problem Based Learning (PBL). The results showed that there was a significant increase in competence, attitudes, and psychomotor in the four study programs that were modelled. Therefore, it can be concluded that the implementation of learning strategies in Lesson study for Learning Community is needed to be used to improve the competence, attitude and psychomotor of science students.

    2013-01-01

    Clostridium botulinum type C and D strains recently have been found to produce PLC on egg yolk agar plates. To characterize the gene, enzymatic and biological activities of C. botulinum PLCs (Cb-PLCs), the cb-plc genes from 8 strains were sequenced, and 1 representative gene was cloned and expressed as a recombinant protein. The enzymatic and hemolytic activities of the recombinant Cb-PLC were measured and compared with those of the Clostridium perfringens alpha-toxin. Each of the eight cb-plc genes encoded a 399 amino acid residue protein preceded by a 27 residue signal peptide. The protein consists of 2 domains, the N- and C-domains, and the overall amino acid sequence identity between Cb-PLC and alpha-toxin was greater than 50%, suggesting that Cb-PLC is homologous to the alpha-toxin. The key residues in the N-domain were conserved, whereas those in the C-domain which are important in membrane interaction were different than in the alpha-toxin. As expected, Cb-PLC could hydrolyze egg yolk phospholipid, p-nitrophenylphosphorylcholine, and sphingomyelin, and also exhibited hemolytic activity;however, its activities were about 4- to over 200-fold lower than those of alpha-toxin. Although Cb-PLC showed weak enzymatic and biological activities, it is speculated that Cb-PLC might play a role in the pathogenicity of botulism or for bacterial survival.

  12. Learning Communities in Undergraduate STEM Education: A Quantitative Analysis of how Sense of Community Influences Retention of Students

    NASA Astrophysics Data System (ADS)

    Archie, T.; Newman, P.

    2012-12-01

    Countless programs are aimed at retaining first year college students in their majors and at their institutions. Additionally, first year students in STEM majors are retained at lower rates, than non-STEM majors. Previous research has shown that students who leave the institution are not as academically and socially integrated into the campus community than students who persist at an institution. Residential learning communities can be thought of as a retention tool by enhancing the academic and social integration of their participants. Academic integration has historically been measured by academic success as indicated by GPA, while social integration has been more difficult to measure. We adapted the Sense of Community Index (SCI) as a measure of social integration. Sense of community (SOC) has been defined as ''a feeling that members have of belonging, a feeling that members matter to one another and to the group, and a shared faith that members' needs will be met through their commitment to be together''. This quantitative study examines sense of community as a means of social integration and explores the relationship between learning communities, students' sense of community, and their intent to persist at a large public university and within their current major. An online survey of 60 first-year college students in a Natural Resources College, examined the relationships between learning community participation, sense of community, and student retention. A logistic regression of sense of community was very effective in predicting students' intent to stay or leave the institution. Structural equation models showed that sense of community was strongly positively related to a students' intent to stay or leave the institution for non-learning community participants, but not for learning community participants. We hypothesized that learning community participants sense of community needs would be more fully met than non-learning community participants. Learning community students showed a weak correlation between sense of community and intent to persist in their major, indicating that these students' departure decisions were based on factors other than sense of community. These finding were consistent with previous research of sense of community which has supported this construct as a needs based hierarchical theory. For example, if students' sense of community needs are met, then they can focus on higher level needs, such as academic success. Conversely, if students' sense of community needs are not being fully met, then this factor remains salient in terms of influencing their departure decision. Our results suggest that learning communities fulfill students' sense of community needs, thus this factor has less influence on learning community participants' decision to leave the institution than their counterparts who do not participate in a learning community. Our results suggest that learning communities are effective in fulfilling students' sense of community needs, thus allowing them to focus their energies on higher order needs such as academic success.

    Tang, Tricia S; Nwankwo, Robin; Whiten, Yolanda; Oney, Christina

    2012-01-01

    The purpose of this study was to examine the feasibility and acceptability of training peers to function as lifestyle coaches and to deliver a church-based lifestyle modification program. We recruited 6 African-American adults to participate in an 8-hour peer lifestyle coach (PLC) training program followed by a subsequent 2-hour booster session. The PLC training program addressed several key areas, including: (1) developing empowerment-based facilitation, active listening, and behavior change skills; (2) learning self-management strategies (eg, reading food labels, counting calories); (3) practicing session delivery; and (4) interpreting clinical lab results. Training evaluation was conducted retrospectively (immediately following the delivery of the diabetes prevention intervention rather than after the 8-hour training session) and measured program satisfaction and efficacy from the perspective of participants. Peer lifestyle coaches' confidence levels for performing core skills (eg, asking open-ended questions, 5-step behavioral goal-setting process) and advanced skills (eg, addressing resistance, discussing sensitive topics) were uniformly high. Similarly, PLCs were very satisfied with the length of training, balance between content and skills development, and preparation for leading group- and individual-based support activities. Findings suggest that it is feasible to customize a PLC training program that is acceptable to participants and that equips participants with the knowledge and skills to facilitate a church-based diabetes prevention intervention.

    PubMed

    Ezeonwu, Mabel; Berkowitz, Bobbie; Vlasses, Frances R

    2014-01-01

    This article describes a model of teaching community health nursing that evolved from a long-term partnership with a community with limited existing health programs. The partnership supported RN-BSN students' integration in the community and resulted in reciprocal gains for faculty, students and community members. Community clients accessed public health services as a result of the partnership. A blended learning approach that combines face-to-face interactions, service learning and online activities was utilized to enhance students' learning. Following classroom sessions, students actively participated in community-based educational process through comprehensive health needs assessments, planning and implementation of disease prevention and health promotion activities for community clients. Such active involvement in an underserved community deepened students' awareness of the fundamentals of community health practice. Students were challenged to view public health from a broader perspective while analyzing the impacts of social determinants of health on underserved populations. Through asynchronous online interactions, students synthesized classroom and community activities through critical thinking. This paper describes a model for teaching community health nursing that informs students' learning through blended learning, and meets the demands for community health nursing services delivery. © 2013 Wiley Periodicals, Inc.

    Voss, Heather C; Mathews, Launa Rae; Fossen, Traci; Scott, Ginger; Schaefer, Michele

    2015-01-01

    Academic partnerships with hospitals and health care agencies for authentic clinical learning have become a major focus of schools of nursing and professional nursing organizations. Formal academic partnerships in community settings are less common despite evolving models of care delivery outside of inpatient settings. Community-Academic partnerships are commonly developed as a means to engage nursing students in service-learning experiences with an emphasis on student outcomes. The benefit of service-learning projects on community partners and populations receiving the service is largely unknown primarily due to the lack of structure for identifying and measuring outcomes specific to service-learning. Nursing students and their faculty engaged in service-learning have a unique opportunity to collaborate with community partners to evaluate benefits of service-learning projects on those receiving the service. This article describes the development of a service-learning framework as a first step toward successful measurement of the benefits of undergraduate nursing students' service-learning projects on community agencies and the people they serve through a collaborative community-academic partnership.

    2018-05-01

    The purpose of this study is to provide an alternative model of professional learning community for primary school teachers in improving the knowledge and professional skills. This study is a qualitative research with case study method with data collection is an interview, observation and document and triangulation technique for validation data that focuses on thirteen people 5th grade elementary school teacher. The results showed that by joining a professional learning community, teachers can share both experience and knowledge to other colleagues so that they can be able to continue to improve and enhance the quality of their learning. This happens because of the reflection done together before, during and after the learning activities. It was also revealed that by learning in a professional learning community, teachers can learn in their own way, according to need, and can collaborate with their colleagues in improving the effectiveness of learning. Based on the implementation of professional learning community primary school teachers can be concluded that teachers can develop the curriculum, the students understand the development, overcome learning difficulties faced by students and can make learning design more effective and efficient.

    2015-10-01

    The purpose of this study was to explore the students' perspectives on the phenomenon of online learning communities while enrolled in a graduate dental hygiene program. A qualitative case study method was designed to investigate the learners' experiences with communities in an online environment. A cross-sectional purposive sampling method was used. Interviews were the data collection method. As the original data were being analyzed, the researchers noted a pattern evolved indicating the phenomenon developed in stages. The data were re-analyzed and validated by 2 member checks. The participants' experiences revealed an e-model consisting of 3 stages of formal learning community development as core courses in the curriculum were completed and 1 stage related to transmuting the community to an informal entity as students experienced the independent coursework in the program. The development of the formal learning communities followed 3 stages: Building a Foundation for the Learning Community, Building a Supportive Network within the Learning Community and Investing in the Community to Enhance Learning. The last stage, Transforming the Learning Community, signaled a transition to an informal network of learners. The e-model was represented by 3 key elements: metamorphosis of relationships, metamorphosis through the affective domain and metamorphosis through the cognitive domain, with the most influential element being the affective development. The e-model describes a 4 stage process through which learners experience a metamorphosis in their affective, relationship and cognitive development. Synergistic learning was possible based on the interaction between synergistic relationships and affective actions. Copyright © 2015 The American Dental Hygienists’ Association.

    ESO is currently in the final phase of the standardization process for PC-based Programmable Logical Controllers (PLCs) as the new platform for the development of control systems for future VLT/VLTI instruments. The standard solution used until now consists of a Local Control Unit (LCU), a VME-based system having a CPU and commercial and proprietary boards. This system includes several layers of software and many thousands of lines of code developed and maintained in house. LCUs have been used for several years as the interface to control instrument functions but now are being replaced by commercial off-the-shelf (COTS) systems based on BECKHOFF Embedded PCs and the EtherCAT fieldbus. ESO is working on the completion of the software framework that enables a seamless integration into the VLT control system in order to be ready to support upcoming instruments like ESPRESSO and ERIS, that will be the first fully VLT compliant instruments using the new standard. The technology evaluation and standardization process has been a long and combined effort of various engineering disciplines like electronics, control and software, working together to define a solution that meets the requirements and minimizes the impact on the observatory operations and maintenance. This paper presents the challenges of the standardization process and the steps involved in such a change. It provides a technical overview of how industrial standards like EtherCAT, OPC-UA, PLCOpen MC and TwinCAT can be used to replace LCU features in various areas like software engineering and programming languages, motion control, time synchronization and astronomical tracking.

  16. The community comes to campus: the Patient and Community Fair.

    Towle, Angela; Godolphin, William; Kline, Cathy

    2015-08-01

    Community-based learning connects students with local communities so that they learn about the broad context in which health and social care is provided; however, students usually interact with only one or a few organisations that serve a particular population. One example of a community-based learning activity is the health fair in which students provide health promotion and screening for local communities. We adapted the health fair concept to develop a multi-professional educational event at which, instead of providing service, students learn from and about the expertise and resources of not-for-profit organisations. The fair is an annual 1-day event that students can attend between, or in place of, classes. Each community organisation has a booth to display information. One-hour 'patient panels' are held on a variety of topics throughout the day. Evaluation methods include questionnaires, exit interviews and visitor tracking sheets. Over 5 years (2009-2013), the fair increased in size with respect to estimated attendance, number of participating organisations, number of patient panels and number of students for whom the fair is a required curriculum component. Students learn about a range of patient experiences and community resources, and information about specific diseases or conditions. The fair is an efficient way for students to learn about a range of community organisations. It fosters university-community engagement through continuing connections between students, faculty members and community organisations. Lessons learned include the need for community organisations to have techniques to engage students, and ways to overcome challenges of evaluating an informal 'drop-in' event. The fair is an efficient way for students to learn about a range of community organisations. © 2015 John Wiley & Sons Ltd.

  12. How to Trigger Emergence and Self-Organisation in Learning Networks

    NASA Astrophysics Data System (ADS)

    Brouns, Francis; Fetter, Sibren; van Rosmalen, Peter

    The previous chapters of this section discussed why the social structure of Learning Networks is important and present guidelines on how to maintain and allow the emergence of communities in Learning Networks. Chapter 2 explains how Learning Networks rely on social interaction and active participations of the participants. Chapter 3 then continues by presenting guidelines and policies that should be incorporated into Learning Network Services in order to maintain existing communities by creating conditions that promote social interaction and knowledge sharing. Chapter 4 discusses the necessary conditions required for knowledge sharing to occur and to trigger communities to self-organise and emerge. As pointed out in Chap. 4, ad-hoc transient communities facilitate the emergence of social interaction in Learning Networks, self-organising them into communities, taking into account personal characteristics, community characteristics and general guidelines. As explained in Chap. 4 community members would benefit from a service that brings suitable people together for a specific purpose, because it will allow the participant to focus on the knowledge sharing process by reducing the effort or costs. In the current chapter, we describe an example of a peer support Learning Network Service based on the mechanism of peer tutoring in ad-hoc transient communities.

  13. The impact of learning communities on interpersonal relationships among medical students.

    PubMed

    Champaloux, Eve Privman; Keeley, Meg G

    2016-01-01

    Medical students at the University of Virginia (UVA) are mentored and learn within the framework of a four college learning community. Uniquely, these learning communities are used to organize the third-year clerkship rotations. Students were surveyed after their first pre-clinical year and after their clerkship year to determine what the effect of the learning community was on their social and educational interpersonal relationships. Students knew a higher percentage of their college mates after completing their third-year clerkships within the framework of the college system. Students chose peers from within the college system for social and educational interpersonal scenarios statistically more often than what would be expected at random. Small group learning environments that were not formed within the framework of the college system at UVA did not have the same effect on interpersonal relationships, indicating that learning communities are uniquely able to provide a context for relationship building. Students felt more positively about the social and educational effects of the college system after the clerkship year, with a corresponding increase in the strength of their interpersonal bonds with their college peers. This work is the first to investigate the effects of learning communities on interpersonal relationships among medical students and finds that learning communities positively impact both social and educational medical student bonds.

  14. Canada's Composite Learning Index: A path towards learning communities

    NASA Astrophysics Data System (ADS)

    Cappon, Paul; Laughlin, Jarrett

    2013-09-01

    In the development of learning cities/communities, benchmarking progress is a key element. Not only does it permit cities/communities to assess their current strengths and weaknesses, it also engenders a dialogue within and between cities/communities on the means of enhancing learning conditions. Benchmarking thereby is a potentially motivational tool, energising further progress. In Canada, the Canadian Council on Learning created the world's first Composite Learning Index (CLI), the purpose of which is to measure the conditions of learning nationally, regionally and locally. Cities/communities in Canada have utilised the CLI Simulator, an online tool provided by the Canadian Council on Learning, to gauge the change in overall learning conditions which may be expected depending on which particular indicator is emphasised. In this way, the CLI has proved to be both a dynamic and a locally relevant tool for improvement, moreover a strong motivational factor in the development of learning cities/communities. After presenting the main features of the CLI, the authors of this paper sum up the lessons learned during its first 5 years (2006-2010) of existence, also with a view to its transferability to other regions. Indeed, the CLI model was already adopted in Europe by the German Bertelsmann foundation in 2010 and has the potential to be useful in many other countries as well.

  16. Community-based medical education: is success a result of meaningful personal learning experiences?

    PubMed

    Kelly, Len; Walters, Lucie; Rosenthal, David

    2014-01-01

    Community-based medical education (CBME) is the delivery of medical education in a specific social context. Learners become a part of social and medical communities where their learning occurs. Longitudinal integrated clerkships (LICs) are year-long community-based placements where the curriculum and clinical experience is typically delivered by primary care physicians. These programs have proven to be robust learning environments, where learners develop strong communication skills and excellent clinical reasoning. To date, no learning model has been offered to describe CBME. The characteristics of CBME are explored by the authors who suggest that the social and professional context provided in small communities enhances medical education. The authors postulate that meaningfulness is engendered by the authentic context, which develops over time. These relationships with preceptors, patients and the community provide meaningfulness, which in turn enhances learning. The authors develop a novel learning model. They propose that the context-rich environment of CBME allows for meaningful relationships and experiences for students and that such meaningfulness enhances learning.

    2015-01-01

    The purposes of this service learning project were to trial nursing student application of the Community-Based Collaborative Action Research (CBCAR) framework while conducting a community health needs assessment and to assess the effectiveness of the CBCAR framework in providing real-world learning opportunities for enhancing baccalaureate nursing students' public health knowledge. In this case study analysis, the CBCAR framework linked service learning and community health needs assessment with public health nursing core competencies. Fifteen nursing students partnered with collaborative members. Student observational field notes and narrative reflections were analyzed qualitatively for fidelity to the CBCAR framework and to evaluate student public health knowledge. Students successfully employed the CBCAR framework in collaboration with the critical access hospital and community stakeholders to design and conduct the community health needs assessment. Service learning themes were real-world solutions, professional development, community collaboration, and making a difference. Students developed skills in six of the eight domains of the Quad Council's core competencies for public health nurses. Community-Based Collaborative Action Research facilitates collaborative partnerships and relationships throughout the research process. Students benefited by applying what they have learned from their education to a real community who lacks resources. © 2014 Wiley Periodicals, Inc.

  16. Interfacing the Controllogics PLC over Ethernet/IP.

    2001-01-01

    The Allen-Bradley ControlLogix [1] line of programmable logic controllers (PLCs) offers several interfaces: Ethernet, ControlNet, DeviceNet, RS-232 and others. The ControlLogix Ethernet interface module 1756-ENET uses EtherNet/IP, the ControlNet protocol [2], encapsulated in Ethernet packages, with specific service codes [3]. A driver for the Experimental Physics and Industrial Control System (EPICS) has been developed that utilizes this EtherNet/IP protocol for controllers running the vxWorks RTOS as well as a Win32 and Unix/Linux test program. Features, performance and limitations of this interface are presented.

  17. Can your software engineer program your PLC?

    NASA Astrophysics Data System (ADS)

    Borrowman, Alastair J.; Taylor, Philip

    2016-07-01

    The use of Programmable Logic Controllers (PLCs) in the control of large physics experiments is ubiquitous1, 2, 3. The programming of these controllers is normally the domain of engineers with a background in electronics, this paper introduces PLC program development from the software engineer's perspective. PLC programs provide the link between control software running on PC architecture systems and physical hardware controlled and monitored by digital and analog signals. The higher-level software running on the PC is typically responsible for accepting operator input and from this deciding when and how hardware connected to the PLC is controlled. The PLC accepts demands from the PC, considers the current state of its connected hardware and if correct to do so (based upon interlocks or other constraints) adjusts its hardware output signals appropriately for the PC's demands. A published ICD (Interface Control Document) defines the PLC memory locations available to be written and read by the PC to control and monitor the hardware. Historically the method of programming PLCs has been ladder diagrams that closely resemble circuit diagrams, however, PLC manufacturers nowadays also provide, and promote, the use of higher-level programming languages4. Based on techniques used in the development of high-level PC software to control PLCs for multiple telescopes, this paper examines the development of PLC programs to operate the hardware of a medical cyclotron beamline controlled from a PC using the Experimental Physics and Industrial Control System (EPICS), which is also widely used in telescope control5, 6, 7. The PLC used is the new generation Siemens S7-1200 programmed using Siemens Pascal based Structured Control Language (SCL), which is their implementation of Structured Text (ST). The approach described is that from a software engineer's perspective, utilising Siemens Totally Integrated Automation (TIA) Portal integrated development environment (IDE) to create modular PLC programs based upon reusable functions capable of being unit tested without the PLC connected to hardware. Emphasis has been placed on designing an interface between EPICS and SCL that enforces correct operation of hardware through stringent separation of PC accessible PLC memory and hardware I/O addresses used only by the PLC. The paper also introduces the method used to automate the creation, from the same source document, the PLC memory structure (tag) definitions (defining memory used to access hardware I/O and that accessed by the PC) and creation of the PC program data structures (EPICS database records) used to access the permitted PLC addresses. From direct experience this paper demonstrates the advantages of PLC program development being shared between electronic and software engineers, to enable use of the most appropriate processes from both the perspective of the hardware and the higher-level software used to control it.

    Being heavily visually-oriented, I am a firm believer in communication and conveying emotions through the art of color, motion, and transformation. A four-part online training course was created in PowerPoint and needed to be translated over into a Flash format. Issues with the Powerpoint were that the size of the files caused noticeable delays when placed online, there were compatibility issues, and from a composition and design perspective, color schemes and layout left much to be desired. High contrast, pixilated yellow text spiraling and flying on to a background of overly rich hues of blue with cheesy gradient patterns was just not appeasing to my eye, along with the menu directory buttons located at the top resembling blue pills of NyQuil on top of a stale gray border that had nothing to do with the background. The course itself is extremely broad and verbose, and will get monotonous very soon after starting. Moving about the course was very cumbersome as well. efficient by drastically reducing the size (The file size of all four parts of the actual course combined will ultimately not even be a fifth as big as one part of the original PowerPoint alone!); along with that, the course was made to be more interactive and user-friendly, as well as pleasing to the eye. Upon being viewed by fellow co-workers, nothing but positive feedback has been received. When beginning the presentation, onscreen comes a 3' 2" chubby, balding professor, who is a master in his knowledge of Programmable Logic Controllers (PLCs). He introduces himself and presents all of his vast knowledge over PLCs in a fun and innovative manner, making it much easier to acquire the information presented. A Scene Selection feature has been added making it a lot easier to jump from part to part and the back and forth arrows are much easier to utilize, and they are both less obtrusive than its PowerPoint predecessor.

    2009-01-01

    Nursing faculty need to understand the unique aspects of online learning environments and develop new pedagogies for teaching in the virtual classroom. The concept of community is important in online learning and a strong sense of community can enhance student engagement and improve learning outcomes in online courses. Student perceptions of community in online learning environments were explored in this study. Five focus group sessions were held and online nursing students were asked to give examples of experiences related to sense of community. Fifteen major themes emerged: class structure, required participation, teamwork, technology, becoming, commonalities, disconnects, mutual exchange, online etiquette, informal discussions, aloneness, trepidation, unknowns, nonverbal communication and anonymity. Themes sorted into the categories of structural, processual and emotional factors. Theme descriptions show how sense of community can be enhanced and/or diminished in online courses. This study adds depth and detail to the limited body of research on sense of community in distance education in nursing courses.

    2016-04-01

    Collaborative forest governance arrangements have been viewed as promising for sustainable forestry because they allow local communities to participate directly in management and benefit from resource use or protection. Such arrangements are strengthened through social learning during management activities that can enhance capacity to solve complex problems. Despite significant research on social learning in collaborative environmental governance, it is not clear how social learning evolves over time, who influences social learning, and whether learning influences management effectiveness. This study investigates how social learning outcomes change over time, using an in-depth study of a community forest in Canada. Personal interviews, focus group meetings, and participant observation revealed that most participants started engaging in community forestry with limited knowledge and learned as they participated in management activities. However, as the community forest organization became effective at complying with forestry legislation, learning opportunities and outcomes became more restricted. Our results run contrary to the prevalent view that opportunities for and outcomes of social learning become enlarged over time. In our case, learning how to meet governmental requirements increased professionalism and reduced opportunities for involvement and learning to a smaller group. Our findings suggest the need to further test propositions about social learning and collaborative governance, particularly to determine how relationships evolve over time.

    2016-01-01

    Background Medical students at the University of Virginia (UVA) are mentored and learn within the framework of a four college learning community. Uniquely, these learning communities are used to organize the third-year clerkship rotations. Methods Students were surveyed after their first pre-clinical year and after their clerkship year to determine what the effect of the learning community was on their social and educational interpersonal relationships. Results Students knew a higher percentage of their college mates after completing their third-year clerkships within the framework of the college system. Students chose peers from within the college system for social and educational interpersonal scenarios statistically more often than what would be expected at random. Small group learning environments that were not formed within the framework of the college system at UVA did not have the same effect on interpersonal relationships, indicating that learning communities are uniquely able to provide a context for relationship building. Students felt more positively about the social and educational effects of the college system after the clerkship year, with a corresponding increase in the strength of their interpersonal bonds with their college peers. Conclusion This work is the first to investigate the effects of learning communities on interpersonal relationships among medical students and finds that learning communities positively impact both social and educational medical student bonds.

  3. Creating and Testing Simulation Software

    Heinich, Christina M.

    2013-01-01

    The goal of this project is to learn about the software development process, specifically the process to test and fix components of the software. The paper will cover the techniques of testing code, and the benefits of using one style of testing over another. It will also discuss the overall software design and development lifecycle, and how code testing plays an integral role in it. Coding is notorious for always needing to be debugged due to coding errors or faulty program design. Writing tests either before or during program creation that cover all aspects of the code provide a relatively easy way to locate and fix errors, which will in turn decrease the necessity to fix a program after it is released for common use. The backdrop for this paper is the Spaceport Command and Control System (SCCS) Simulation Computer Software Configuration Item (CSCI), a project whose goal is to simulate a launch using simulated models of the ground systems and the connections between them and the control room. The simulations will be used for training and to ensure that all possible outcomes and complications are prepared for before the actual launch day. The code being tested is the Programmable Logic Controller Interface (PLCIF) code, the component responsible for transferring the information from the models to the model Programmable Logic Controllers (PLCs), basic computers that are used for very simple tasks.

  4. Using a multi-state Learning Community as an implementation strategy for immediate postpartum long-acting reversible contraception.

    Implementation strategies are imperative for the successful adoption and sustainability of complex evidence-based public health practices. Creating a learning collaborative is one strategy that was part of a recently published compilation of implementation strategy terms and definitions. In partnership with the Centers for Disease Control and Prevention and other partner agencies, the Association of State and Territorial Health Officials recently convened a multi-state Learning Community to support cross-state collaboration and provide technical assistance for improving state capacity to increase access to long-acting reversible contraception (LARC) in the immediate postpartum period, an evidence-based practice with the potential for reducing unintended pregnancy and improving maternal and child health outcomes. During 2015-2016, the Learning Community included multi-disciplinary, multi-agency teams of state health officials, payers, clinicians, and health department staff from 13 states. This qualitative study was conducted to better understand the successes, challenges, and strategies that the 13 US states in the Learning Community used for increasing access to immediate postpartum LARC. We conducted telephone interviews with each team in the Learning Community. Interviews were semi-structured and organized by the eight domains of the Learning Community. We coded transcribed interviews for facilitators, barriers, and implementation strategies, using a recent compilation of expert-defined implementation strategies as a foundation for coding the latter. Data analysis showed three ways that the activities of the Learning Community helped in policy implementation work: structure and accountability, validity, and preparing for potential challenges and opportunities. Further, the qualitative data demonstrated that the Learning Community integrated six other implementation strategies from the literature: organize clinician implementation team meetings, conduct educational meetings, facilitation, promote network weaving, provide ongoing consultation, and distribute educational materials. Convening a multi-state learning collaborative is a promising approach for facilitating the implementation of new reimbursement policies for evidence-based practices complicated by systems challenges. By integrating several implementation strategies, the Learning Community serves as a meta-strategy for supporting implementation.

    2013-01-01

    Service learning is becoming a keystone of the undergraduate learning experience. At Stonehill College, we implemented a service learning course, called a Learning Community, in Neuroscience. This course was created to complement the basic research available to Stonehill Neuroscience majors with experience in a more applied and “clinical” setting. The Neuroscience Learning Community is designed to promote a deep understanding of Neuroscience by combining traditional classroom instruction with clinical perspectives and real-life experiences. This Neuroscience Learning Community helps students translate abstract concepts within the context of neurodevelopment by providing students with contextual experience in a real-life, unscripted setting. The experiential learning outside of the classroom enabled students to participate in informed discussions in the classroom, especially with regard to neurodevelopmental disorders. We believe that all students taking this course gain an understanding of the importance of basic and applied Neuroscience as it relates to the individual and the community. Students also have used this concrete, learning-by-doing experience to make informed decisions about career paths and choice of major. PMID:24319392

  10. Trust-based Access Control in Virtual Learning Community

    NASA Astrophysics Data System (ADS)

    Wang, Shujuan; Liu, Qingtang

    The virtual learning community is an important application pattern of E-Learning. It emphasizes the cooperation of the members in the community, the members would like to share their learning resources, to exchange their experience and complete the study task together. This instructional mode has already been proved as an effective way to improve the quality and efficiency of instruction. At the present time, the virtual learning communities are mostly designed using static access control policy by which the access permission rights are authorized by the super administrator, the super administrator assigns different rights to different roles, but the virtual and social characteristics of virtual learning community make information sharing and collaboration a complex problem, the community realizes its instructional goal only if the members in it believe that others will offer the knowledge they owned and believe the knowledge others offered is well-meaning and worthy. This paper tries to constitute an effective trust mechanism, which could promise favorable interaction and lasting knowledge sharing.

    2018-04-01

    Community-based participatory research (CBPR) and service-learning are unique experiential approaches designed to train medical students how to provide individualized patient care from a population perspective. Medical schools in the US are required to provide support for service-learning and community projects. Despite this requirement, few medical schools offer structured service-learning. We developed the Community Action Research Track (CART) to integrate population medicine, health promotion/disease prevention and the social determinants of health into the medical school curriculum through CBPR and service-learning experiences. This article provides an overview of CART and reports the program impact based on students' participation, preliminary evaluations and accomplishments. CART is an optional 4‑year service-learning experience for medical students interested in community health. The curriculum includes a coordinated longitudinal program of electives, community service-learning and lecture-based instruction. From 2009-2015, 146 CART students participated. Interests in public health (93%), community service (73%), primary care (73%), CBPR (60%) and community medicine (60%) were the top reasons for enrolment. Significant improvements in mean knowledge were found when measuring the principles of CBPR, levels of prevention, determining health literacy and patient communication strategies (all p's < 0.05). Most students (73%) were satisfied with CART. Projects were disseminated by at least 65 posters and four oral presentations at local, national and international professional meetings. Six manuscripts were published in peer-reviewed journals. CART is an innovative curriculum for training future physicians to be community-responsive physicians. CART can be replicated by other medical schools interested in offering a longitudinal CBPR and service-learning track in an urban metropolitan setting.

    Service-learning partnerships between universities and surrounding communities striving to create systems-level change must consider an emphasis in critical community service; a community centered paradigm where students are taught to work with communities to better understand contexts surrounding a social problem, as opposed to merely volunteering to provide a service to a community. The Adolescent Diversion Project (ADP), which has been operating for over 30 years, demonstrates critical community service through the type of relationship built between students and the local community. This article describes: a qualitative study with ADP students, the historical context of ADP, what and how students learned through their involvement in ADP, and reframes the work of this project as a form of service-learning pedagogy. Inductive content analysis was employed to identify underlying themes across participants related to their personal experiences of ADP and its impact in their lives. Findings were compared with service-learning outcomes and other quantitative studies conducted with past ADP cohorts from the literature. Consistent with past studies, ADP students become more negative toward social systems involved with their youth. This finding may explain an increase in feelings of political commitment following involvement in ADP. Consistent with service-learning outcomes, results demonstrate that ADP should be further documented as not only an effective community-based program but also as an exemplar in the pedagogy of service-learning. This study highlights why service-learning opportunities for students are not just one way to teach students, they are opportunities to bridge relationships within communities, bring life to theoretical concepts, and build the foundations necessary for educated citizens that will one day take lead roles in our society.

    Legionella pneumophila is a water-borne bacterium that causes pneumonia in humans. PlcA and PlcB are two previously defined L. pneumophila proteins with homology to the phosphatidylcholine-specific phospholipase C (PC-PLC) of Pseudomonas fluorescens. Additionally, we found that Lpg0012 shows similarity to PLCs and has been shown to be a Dot/Icm-injected effector, CegC1, which is designated here as PlcC. It remained unclear, however, whether these L. pneumophila proteins exhibit PLC activity. PlcC expressed in Escherichia coli hydrolyzed a broad phospholipid spectrum, including PC, phosphatidylglycerol (PG), and phosphatidylinositol. The addition of Zn2+ ions activated, whereas EDTA inhibited, PlcC-derived PLC activity. Protein homology search revealed that the three Legionella enzymes and P. fluorescens PC-PLC share conserved domains also present in uncharacterized fungal proteins. Fifteen conserved amino acids were essential for enzyme activity as identified via PlcC mutagenesis. Analysis of defined L. pneumophila knock-out mutants indicated Lsp-dependent export of PG-hydrolyzing PLC activity. PlcA and PlcB exhibited PG-specific activity and contain a predicted Sec signal sequence. In line with the reported requirement of host cell contact for Dot/Icm-dependent effector translocation, PlcC showed cell-associated PC-specific PLC activity after bacterial growth in broth. A PLC triple mutant, but not single or double mutants, exhibited reduced host killing in a Galleria mellonella infection model, highlighting the importance of the three PLCs in pathogenesis. In summary, we describe here a novel Zn2+-dependent PLC family present in Legionella, Pseudomonas, and fungi with broad substrate preference and function in virulence. PMID:23457299

    In large fusion experiments, such as tokamak devices, there is a common trend for slow control systems. Because of complexity of the plants, the so-called `Standard Model' (SM) in slow control has been adopted on several tokamak machines. This model is based on a three-level hierarchical control: 1) High-Level Control (HLC) with a supervisory function; 2) Medium-Level Control (MLC) to interface and concentrate I/O field equipments; 3) Low-Level Control (LLC) with hard real-time I/O function, often managed by PLCs. FTU control system designed with SM concepts has underwent several stages of developments in its fifteen years duration of runs. The latest evolution was inevitable, due to the obsolescence of the MLC CPUs, based on VME-MOTOROLA 68030 with OS9 operating system. A large amount of C code was developed for that platform to route the data flow from LLC, which is constituted by 24 Westinghouse Numalogic PC-700 PLCs with about 8000 field-points, to HLC, based on a commercial Object-Oriented Real-Time database on Alpha/CompaqTru64 platform. Therefore, we have to look for cost-effective solutions and finally a CompactPCI-Intel x86 platform with Linux operating system was chosen. A software porting has been done, taking into account the differences between OS9 and Linux operating system in terms of Inter/Network Processes Communications and I/O multi-ports serial driver. This paper describes the hardware/software architecture of the new MLC system, emphasizing the reliability and the low costs of the open source solutions. Moreover, a huge amount of software packages available in open source environment will assure a less painful maintenance, and will open the way to further improvements of the system itself.

  17. Dosing of Milrinone in Preterm Neonates to Prevent Postligation Cardiac Syndrome: Simulation Study Suggests Need for Bolus Infusion.

    Milrinone has been suggested as a possible first-line therapy for preterm neonates to prevent postligation cardiac syndrome (PLCS) through decreasing systemic vascular resistance and increasing cardiac contractility. The optimal dosing regimen, however, is not known. To model the dosing of milrinone in preterm infants for prevention of PLCS after surgical closure of patent ductus arteriosus (PDA). Milrinone time-concentration profiles were simulated for 1,000 subjects using the volume of distribution and clearance estimates based on one compartmental population pharmacokinetic model by Paradisis et al. [Arch Dis Child Fetal Neonatal Ed 2007;92:F204-F209]. Dose optimization was based on retrospectively collected demographic data from neonates undergoing PDA ligation in Estonian PICUs between 2012 and 2014 and existing pharmacodynamic data. The target plasma concentration was set at 150-200 ng/ml. The simulation study used demographic data from 31 neonates who underwent PDA ligation. The median postnatal age was 13 days (range: 3-29) and weight was 760 g (range: 500-2,351). With continuous infusion of milrinone 0.33 μg/kg/min, the proportion of subjects within the desired concentration range was 0% by 3 h, 36% by 6 h, and 61% by 8 h; 99% of subjects exceeded the range by 18 h. The maximum proportion of total simulated concentrations in the target range was attained with a bolus infusion of 0.73 μg/kg/min for 3 h followed by a 0.16-μg/kg/min maintenance infusion. Mathematical simulations suggest that in preterm neonates the plasma time-concentration profile of milrinone can be optimized with a slow loading dose followed by maintenance infusion. © 2016 S.

    The thermal/vacuum facilities located at the Goddard Space Flight Center (GSFC) have supported both manned and unmanned space flight since the 1960s. Of the 11 facilities, currently 10 of the systems are scheduled for refurbishment and/or replacement as part of a 5-year implementation. Expected return on investment includes the reduction in test schedules, improvements in the safety of facility operations, reduction in the complexity of a test and the reduction in personnel support required for a test. Additionally, GSFC will become a global resource renowned for expertise in thermal engineering, mechanical engineering and for the automation of thermal/vacuum facilities and thermal/vacuum tests. Automation of the thermal/vacuum facilities includes the utilization of Programmable Logic Controllers (PLCs) and the use of Supervisory Control and Data Acquisition (SCADA) systems. These components allow the computer control and automation of mechanical components such as valves and pumps. In some cases, the chamber and chamber shroud require complete replacement while others require only mechanical component retrofit or replacement. The project of refurbishment and automation began in 1996 and has resulted in the computer control of one Facility (Facility #225) and the integration of electronically controlled devices and PLCs within several other facilities. Facility 225 has been successfully controlled by PLC and SCADA for over one year. Insignificant anomalies have occurred and were resolved with minimal impact to testing and operations. The amount of work remaining to be performed will occur over the next four to five years. Fiscal year 1998 includes the complete refurbishment of one facility, computer control of the thermal systems in two facilities, implementation of SCADA and PLC systems to support multiple facilities and the implementation of a Database server to allow efficient test management and data analysis.

    This study was conducted to compare the cumulative survival rates (CSRs) and the incidence of postloading complications (PLCs) between a bone-level internal connection system (ICS-BL) and an external connection system (ECS). The medical records of patients treated with either a ICS-BL or ECS between 2007 and 2010 at Asan Medical Center were reviewed. PLCs were divided into two categories: biological and technical. Biological complications included >4 mm of probing pocket depth, thread exposure in radiographs, and soft tissue complications, whereas technical complications included chipping of the veneering material, fracture of the implant, fracture of the crown, loosening or fracture of the abutment or screw, loss of retention, and loss of access hole filling material. CSRs were determined by a life-table analysis and compared using the log-rank chi-square test. The incidence of PLC was compared with the Pearson chi-squared test. A total of 2,651 implants in 1,074 patients (1,167 ICS-BLs in 551 patients and 1,484 ECSs in 523 patients) were analyzed. The average observation periods were 3.4 years for the ICS-BLs and 3.1 years for the ECSs. The six-year CSR of all implants was 96.1% (94.9% for the ICS-BLs and 97.1% for the ECSs, P=0.619). Soft tissue complications were more frequent with the ECSs (P=0.005) and loosening or fracture of the abutment or screw occurred more frequently with the ICS-BLs (P<0.001). Within the limitations of this study, the ICS-BL was more prone to technical complications while the ECS was more vulnerable to biological complications.

  1. High-speed electro-optic polymers: mm-Wave applications and silica planar lightwave circuit integration

    NASA Astrophysics Data System (ADS)

    Chang, Daniel H.

    The development of high speed polymer electro-optic modulators has seen steady and significant progress in recent years, enabling novel applications in RF-Photonics. Two of these are described in this Thesis: an Opto-Electronic Oscillator (OEO), which is a hybrid RF and optical oscillator capable of high spectral purity, and Photonic Time-Stretch, which is a signal processing technique for waveform spectral shifting with application to photonically-assisted A/D conversion. In both cases, the operating frequencies achieved have been the highest demonstrated to date. Application of this promising material to more complicated devices, however, is stymied by insertion loss performance. Current loss figures, while acceptable for single modulators, are too high for large arrays of modulators or intrinsically long devices such as AWGs or photonic-RF phase shifters. This is especially frustrating in light of a key virtue which polymers possess as a photonic material: its photolithographic process-ability makes patterning complex devices possible. Indeed, the current ascendancy of silica-based waveguide devices can be attributed largely to the same reason. In this Thesis, we also demonstrate the first hybrid device composed of silica planar lightwave circuits (PLCs) and polymer planar waveguides. Our approach utilizes grayscale lithography to enable vertical coupling between polymer and silica layers, minimizing entanglement of their respective fabrication processes. We have achieved coupling excess loss figures on the order of 1dB. We believe this is the natural next step in the development of electro-optic polymer devices. The two technologies are highly complementary. Silica PLCs, with excellent propagation loss and fiber coupling, are ideally suited for long passive waveguiding. By endowing them with the high-speed phase shifting capability offered by polymers, active wideband photonic devices of increasing complexity and array size can be contemplated.

The context of this research is a hybrid distance learning of French for specific purposes, delivered through the platform UNIV-RcT (Strasbourg University), which combines collaborative activities for the realization of a common problem-solving task online. The study focuses on a couple of aspects: on-line interactions carried out in small, tutored groups and the process of community building online. By analyzing the learner's perceptions of community and collaborative learning, we have tried to understand the process of building and maintenance of online learning community and to see to what extent the collaborative distance learning contribute to the development of the competence expectations at the end of the course. The analysis of the results allows us to distinguish the advantages and limitations of this type of e-learning and thus evaluate their pertinence.

  14. Learning Nursing in the Workplace Community: The Generation of Professional Capital

    NASA Astrophysics Data System (ADS)

    Gobbi, Mary

    This chapter explores the connections between learning, working and professional communities in nursing. It draws on experiences and research in nursing practice and education, where not only do isolated professionals learn as a result of their actions for patients and others, but those professionals are part of a community whose associated networks enable learning to occur. Several characteristics of this professional community are shared with those found in Communities of Practice (CoPs) (Lave and Wenger, 1991; Wenger, 1998), but the balance and importance of many elements can differ. For instance, whilst Lave and Wenger (1991) describe many aspects of situated learning in CoPs that apply to nurses, their model is of little help in understanding the ways in which other professions as well as patients/clients and carers influence the development of nursing practice. Therefore, I shall argue that it is not just the Community of Practice that we need to consider

  5. Improving Health with Science: Exploring Community-Driven Science Education in Kenya

    NASA Astrophysics Data System (ADS)

    Leak, Anne Emerson

    This study examines the role of place-based science education in fostering student-driven health interventions. While literature shows the need to connect science with students' place and community, there is limited understanding of strategies for doing so. Making such connections is important for underrepresented students who tend to perceive learning science in school as disconnected to their experiences out of school (Aikenhead, Calabrese-Barton, & Chinn, 2006). To better understand how students can learn to connect place and community with science and engineering practices in a village in Kenya, I worked with community leaders, teachers, and students to develop and study an education program (a school-based health club) with the goal of improving knowledge of health and sanitation in a Kenyan village. While students selected the health topics and problems they hoped to address through participating in the club, the topics were taught with a focus on providing opportunities for students to learn the practices of science and health applications of these practices. Students learned chemistry, physics, environmental science, and engineering to help them address the health problems they had identified in their community. Surveys, student artifacts, ethnographic field notes, and interview data from six months of field research were used to examine the following questions: (1) In what ways were learning opportunities planned for using science and engineering practices to improve community health? (2) In what ways did students apply science and engineering practices and knowledge learned from the health club in their school, homes, and community? and (3) What factors seemed to influence whether students applied or intended to apply what they learned in the health club? Drawing on place-based science education theory and community-engagement models of health, process and structural coding (Saldana, 2013) were used to determine patterns in students' applications of their learning. Students applied learning across health topics they identified as interesting and relevant to their community: hand-washing, disease-prevention, first aid, balanced diet, and water. Students' application of their learning was influenced by internal, external, and relational factors with the community, science education factors, and cultural factors. Some factors, which may have been barriers for students to apply their learning, were turned into supports via bridging strategies used by the students and teacher. Bridging strategies allowed students to connect between their place and science in meaningful ways in the classroom. These strategies were critical in bringing students' place into the classroom and enabling students to apply their learning toward place. The model resulting from the identified factors informed existing models for sociocultural considerations in community-based health interventions. The community-engagement applied practices of science (CAPS) model serves to conceptualize findings in this study and informs an integrated method for using community-engagement education as a stimuli for students to become cultural brokers and improve community health. In addition to focusing on teaching practices of science and encouraging students to apply their learning, this research suggests that bridging strategies can be used to connect science with a students' place in meaningful ways that serve both students and their local communities.
