    Large enrolment science courses play a significant role in educating undergraduate students. The discourse in these classes usually involves an instructor lecturing with little or no student participation, despite calls from current science education reform documents to elicit and utilize students' ideas in teaching. In this study, we used the 5E instructional model to develop and implement four lessons in a large enrolment introductory biology course with multiple opportunities for teacher-student and student-student interaction. Data consisted of video and audio recordings of whole-class and small-group discussions that took place throughout the study. We then used a science classroom discourse framework developed by Mortimer and Scott (2003) to characterize the discursive interactions in each 5E lesson phase. Analysis of the data resulted in two assertions. First, the purpose, communicative approach, patterns of discourse, and teaching interventions were unique to each 5E lesson phase. Second, the type of lesson topic influenced the content of the discourse. We discuss how the findings help characterize the discourse of each phase in a 5E college science lesson and propose a model to understand internalization through discursive interaction using this reform-based approach. We conclude with implications for facilitating discourse in college science lessons and future research. This study provides support for using the discourse framework to characterize discursive interaction in college science courses.

    1997-12-31

    The 1990 Clean Air Act Amendments have required significant reductions in SO{sub 2} and NO{sub x} emissions from fossil fuel-fired power plants in the US. This paper examines some of the key technical lessons learned in Phase I following retrofit of low NO{sub x} systems, FGD systems, and continuous emissions monitors. Some of the key problems encountered have been waterwall wastage as a result of low NO{sub x} burner retrofits; high LOI (carbon) ash as a result of low NO{sub x} operation; high O&M costs associated with CEMs; and the heat rate discrepancy which has arisen between CEMs and conventional heat rate calculations. As Phase II approaches, EPRI and the electric utility industry are investigating improvements in FGD systems (e.g., clear liquor scrubbing), advances in NO{sub x} control technologies, more robust CEM systems, and tools to help in the technology decision-making process.

  11. Modeling Lunar Phases in the Classroom: A Hands-On Interactive Lesson

    NASA Astrophysics Data System (ADS)

    Sarrazine, Angela R.

    2007-12-01

    Using Power-Point technology and hands-on materials, a 45 minute lesson has been created to allow students to explore the cause of lunar phases. Students work in cooperative pairs to model the different phases of the moon. In addition, this lesson does not require a bright light source. Using a partially painted Styrofoam ball, a small cup of Play-dough, a simple, protractor, and a data collection sheet, students observe the lunar phases and measure the angle between the sun and the moon. Students place the moon model in eight different positions simulating its orbit around the earth and record the observed changes. The Power-Point presentation contains three segments. The first section allows the teacher to determine the students’ level of prior knowledge about the moon and to uncover possible misconceptions. The second section facilitates the students’ learning by displaying the proper alignment of the model and the proper viewing position for the students. Finally, the presentation culminates in a review of what the students have just observed. This lesson has been created to meet Georgia Performance Standards (GPS) for 4th grade science regarding the cause of lunar phases. Teacher and student responses to this lesson have been extremely positive.

    In recent years both mass spectrometry (MS) and ion mobility mass spectrometry (IM‐MS) have been developed as techniques with which to study proteins that lack a fixed tertiary structure but may contain regions that form secondary structure elements transiently, namely intrinsically disordered proteins (IDPs). IM‐MS is a suitable method for the study of IDPs which provides an insight to conformations that are present in solution, potentially enabling the analysis of lowly populated structural forms. Here, we describe the IM‐MS data of two IDPs; α‐Synuclein (α‐Syn) which is implicated in Parkinson's disease, and Apolipoprotein C‐II (ApoC‐II) which is involved in cardiovascular diseases. We report an apparent discrepancy in the way that ApoC‐II behaves in the gas phase. While most IDPs, including α‐Syn, present in many charge states and a wide range of rotationally averaged collision cross sections (CCSs), ApoC‐II presents in just four charge states and a very narrow range of CCSs, independent of solution conditions. Here, we compare MS and IM‐MS data of both proteins, and rationalise the differences between the proteins in terms of different ionisation processes which they may adhere to. PMID:25920945

  14. Can lessons designed with Gestalt laws of visual perception improve students' understanding of the phases of the moon?

    NASA Astrophysics Data System (ADS)

    Wistisen, Michele

    There has been limited success teaching elementary students about the phases of the moon using diagrams, personal observations, and manipulatives. One possible reason for this is that instruction has failed to apply Gestalt principles of perceptual organization to the lesson materials. To see if fourth grade students' understanding could be improved, four lessons were designed and taught using the Gestalt laws of Figure-Ground, Symmetry, and Similarity. Students (n = 54) who were taught lessons applying the Gestalt principles scored 12% higher on an assessment than students (n = 51) who only were taught lessons using the traditional methods. Though scores showed significant improvement, it is recommended to follow the American Association for the Advancement of Science guidelines and wait until 9th grade to instruct students about the phases.

    A phase 1/2 clinical trial evaluating dosing, safety, immunogenicity, and overall survival on metastatic colorectal cancer (mCRC) patients after immunotherapy with an advanced generation Ad5 [E1-, E2b-]-CEA(6D) vaccine was performed. We report our extended observations on long-term overall survival and further immune analyses on a subset of treated patients including assessment of cytolytic T cell responses, T-regulatory (Treg) to T-effector (Teff) cell ratios, flow cytometry on peripheral blood mononuclear cells (PBMC), and determination of HLA-A2 status. An overall survival of 20% (median survival of 11 months) was observed during long-term follow-up and no long-term adverse effects were reported. Cytolytic T cell responses increased after immunizations and cell-mediated immune (CMI) responses were induced whether or not patients were HLA-A2 positive or Ad5 immune. PBMC samples from a small subset of patients were available for follow-up immune analyses. It was observed that the levels of carcinoembryonic antigen (CEA) specific CMI activity decreased from their peak values during follow-up in 5 patients analyzed. Preliminary results revealed that activated CD4+ and CD8+ T cells were detected in a post immunization sample exhibiting high CMI activity. Treg to Teff cell ratios were assessed and samples from 3 of 5 patients exhibited a decrease in Treg to Teff cell ratio during the treatment protocol. Based upon the favorable safety and immunogenicity data obtained, we plan to perform an extensive immunologic and survival analysis on mCRC patients to be enrolled in a randomized/controlled clinical trial that investigates Ad5 [E1-, E2b-]-CEA(6D) as a single agent with booster immunizations.

    1996-12-31

    Title IV of the Clean Air Act Amendments of 1990 (CAAA) is concerned with lowering the levels of acid rain in the USA. One of the contributions to acid rain is nitric oxides referred to as NO{sub x}. Title IV seeks NO{sub x} reductions from two groupings of utility steam generators. The first group, known as Phase I, was to have their reductions made by January 1, 1996. The purpose of this paper is to look back at Phase I to see what one can learn for use in Phase II compliance planning. Phase II units are scheduled to be in compliance by January 1, 2000. As such, this paper looks to answer four questions about Phase I units.

  19. Lessons learned with the Active Phasing Experiment: comparison of four optical phasing sensors on a segmented Very Large Telescope

    NASA Astrophysics Data System (ADS)

    Gonte, F.; Surdej, I.

    The adaptive optics capabilities are strongly limited by the quality of the phasing of the primary mirror of the extremely large telescope. Up to date, the Keck telescopes are the only segmented telescope phased with a quality enabling the application of adaptive optics. The Active Phasing Experiment has been installed at the Namyth focus of the Very Large Telescope Melipal during the last 6 months. Its purpose is to understand and compare different technological concepts for an optical phasing sensor dedicated to the European Extremely Large Telescope. The pupil of the telescope is segmented in 61 hexagonal segments by projecting it on an Active Segmented Mirror. The ASM is controlled by a dual wavenlength interferometer made by Fogale Nanotech with a nanometric precision. The segmented pupil is distributed in parallel to four optical phasing sensors. They are a pyramid sensor, a curvature sensor, a phase filtering sensor and a ShackHartmann sensor. They have been developed respectively by Istituto Nazionale di Astrofisica in Florenze, Instituto Astrofisica Canarias in Tenerife, Laboratoire d'Astrophysique de Marseille and ESO. The global behaviour of the optical phasing sensors will be described and preliminary results of the Active Phasing Experiments obtained on sky will be explained. The extrapolation of the results to the EELT and the potential consequences for the adaptive optics will be given. The Active Phasing Experiment has been financed by the European Union and the European Southern Observatory via the Sixth European Union Framework Program for Research and Technological Development under the contract number 011863.

    Early phase clinical trials are an essential component of chemopreventive drug development to identify signals of drug efficacy that can subsequently be explored definitively in phase III trials. Whereas phase I trials focus on safety and identification of optimal dose and schedule for cancer prevention, phase II trials focus on intermediate endpoints that are variably related to cancer development. The United States National Cancer Institute supports a programme devoted to early phase cancer prevention clinical trials. The experience, along with the benefits and limitations of the range of biomarker endpoints used in these studies, are reviewed here. PMID:26635903

    The February 7th 2009 bushfires in Victoria, Australia, resulted in the deaths of 173 individuals, of whom 164 were included in the subsequent DVI operation. The final stage of the International DVI protocol is a debrief, referred to as Phase 5. The Phase 5 operational debrief process conducted in the wake of this disaster was designed for the purpose of developing new strategies in light of this experience. The agencies involved included the Coroners Court of Victoria, the Victorian Institute of Forensic Medicine, the Department of Justice, and Victoria Police. During the course of this debriefing process strategies and protocols were developed which aim to improve the capacity of all agencies to respond and resolve future incidents. This paper outlines the Phase 5 debrief carried out in the 6 months following the final coronial identification board, and details the findings and recommendations made by the agencies involved.

  3. A New, Discontinuous 2 Phases of Aging Model: Lessons from Drosophila melanogaster

    PubMed Central

    Tricoire, Hervé; Rera, Michael

    2015-01-01

    Aging is commonly described as being a continuous process affecting progressively organisms as time passes. This process results in a progressive decrease in individuals fitness through a wide range of both organismal–decreased motor activity, fertility, resistance to stress–and molecular phenotypes–decreased protein and energy homeostasis, impairment of insulin signaling. In the past 20 years, numerous genes have been identified as playing a major role in the aging process, yet little is known about the events leading to that loss of fitness. We recently described an event characterized by a dramatic increase of intestinal permeability to a blue food dye in aging flies committed to die within a few days. Importantly, flies showing this so called ‘Smurf’ phenotype are the only ones, among a population, to show various age-related changes and exhibit a high-risk of impending death whatever their chronological age. Thus, these observations suggest that instead of being one continuous phenomenon, aging may be a discontinuous process well described by at least two distinguishable phases. In this paper we addressed this hypothesis by implementing a new 2 Phases of Aging mathematiCal model (2PAC model) to simulate longevity curves based on the simple hypothesis of two consecutive phases of lifetime presenting different properties. We first present a unique equation for each phase and discuss the biological significance of the 3 associated parameters. Then we evaluate the influence of each parameter on the shape of survival curves. Overall, this new mathematical model, based on simple biological observations, is able to reproduce many experimental longevity curves, supporting the existence of 2 phases of aging exhibiting specific properties and separated by a dramatic transition that remains to be characterized. Moreover, it indicates that Smurf survival can be approximated by one single constant parameter for a broad range of genotypes that we have tested under

We report our extended observations on long-term overall survival and further immune analyses on a subset of treated patients including assessment of cytolytic T cell responses, T regulatory (Treg) to T effector (Teff) cell ratios, flow cytometry on peripheral blood mononuclear cells (PBMCs), and determination of HLA-A2 status. An overall survival of 20 % (median survival 11 months) was observed during long-term follow-up, and no long-term adverse effects were reported. Cytolytic T cell responses increased after immunizations, and cell-mediated immune (CMI) responses were induced whether or not patients were HLA-A2 positive or Ad5 immune. PBMC samples from a small subset of patients were available for follow-up immune analyses. It was observed that the levels of carcinoembryonic antigen (CEA)-specific CMI activity decreased from their peak values during follow-up in five patients analyzed. Preliminary results revealed that activated CD4+ and CD8+ T cells were detected in a post-immunization sample exhibiting high CMI activity. Treg to Teff cell ratios were assessed, and samples from three of five patients exhibited a decrease in Treg to Teff cell ratio during the treatment protocol. Based upon the favorable safety and immunogenicity data obtained, we plan to perform an extensive immunologic and survival analysis on mCRC patients to be enrolled in a randomized/controlled clinical trial that investigates Ad5 [E1-, E2b-]-CEA(6D) as a single agent with booster immunizations.

    that can be achieved using currently available standards and corresponding products and implementations. The AIP-4 integration testing process proved that the integration of heterogeneous data resources available via interoperability arrangements such as WMS, WFS, WCS and WPS indeed works. However, the integration often required various levels of customizations on the client side to accommodate for variations in the service implementations. Those variations seem to be based on both malfunctioning service implementations as well as varying interpretations of or inconsistencies in existing standards. Other interoperability issues identified revolve around missing metadata or using unrecognized identifiers in the description of GEOSS resources. Once such issues are resolved, continuous compliance testing is necessary to ensure minimizing variability of implementations. Once data providers can choose from a set of enhanced implementations for offering their data using consistent interoperability arrangements, the barrier to client and decision support implementation developers will be lowered, leading to true leveraging of earth observation data through GEOSS. AIP-4 results, lessons learnt from previous AIPs 1-3 and close coordination with the Infrastructure Implementation Board (IIB), the successor of the Architecture and Data Committee (ADC), form the basis in the current preparation phase for the next Architecture Implementation Pilot, AIP-5. The Call For Participation will be launched in February and the pilot will be conducted from May to November 2012. The current planning foresees a scenario- oriented approach, with possible scenarios coming from the domains of disaster management, health (including air quality and waterborne diseases), water resource observations, energy, biodiversity and climate change, and agriculture.

  15. Red Sea circulation during marine isotope stage 5e

    NASA Astrophysics Data System (ADS)

    Siccha, Michael; Biton, Eli; Gildor, Hezi

    2015-04-01

    We have employed a regional Massachusetts Institute of Technology oceanic general circulation model of the Red Sea to investigate its circulation during marine isotope stage (MIS) 5e, the peak of the last interglacial, approximately 125 ka before present. Compared to present-day conditions, MIS 5e was characterized by higher Northern Hemisphere summer insolation, accompanied by increases in air temperature of more than 2°C and global sea level approximately 8 m higher than today. As a consequence of the increased seasonality, intensified monsoonal conditions with increased winds, rainfall, and humidity in the Red Sea region are evident in speleothem records and supported by model simulations. To assess the dominant factors responsible for the observed changes, we conducted several sensitivity experiments in which the MIS 5 boundary conditions or forcing parameters were used individually. Overall, our model simulation for the last interglacial maximum reconstructs a Red Sea that is colder, less ventilated and probably more oligotrophic than at present day. The largest alteration in Red Sea circulation and properties was found for the simulation of the northward displacement and intensification of the African tropical rain belt during MIS 5e, leading to a notable increase in the fresh water flux into the Red Sea. Such an increase significantly reduced the Red Sea salinity and exchange volume of the Red Sea with the Gulf of Aden. The Red Sea reacted to the MIS 5e insolation forcing by the expected increase in seasonal sea surface temperature amplitude and overall cooling caused by lower temperatures during deep water formation in winter.

  1. El Nino Activity During MIS 5e in Peru

    NASA Astrophysics Data System (ADS)

    Rein, B.; Sirocko, F.

    2004-12-01

    Oceanography and climate along the coast of Peru is fundamentally linked to ENSO variability with stronger lithic flux into the sea and reduced marine bioproductivity during El Nino events. A 19 m long piston core with laminated marine sediments has been recovered on the edge of the Peruvian shelf (12 03'S, 77 40W, 184 m waterdepth) during cruise Sonne-147 in 2000. We present the lower 6 meters of this core that cover the time between 100 to 130 kyr before the present (BP). SST has been estimated from alkenone analysis with a mean temporal resolution of 300 years. Color logging along the core at 2 mm intervals revealed high resolution proxy data (3 to 30 a) for the precipitation on the continent (fine-grained lithics) and marine bioproduction (photosynthesis pigments: chlorines, carotenoids). Proxy data show that a major change occurred around 123 kyr BP. Mean sedimentation rate which is largely controlled by lithics dropped from 40-70 cm/kyr to 18 cm/kyr after 123 kyr BP. Contemporaneously SST start to decline towards the early Glacial level that is reached between 118 to 116 ka during the time of glacial inception. We conclude that stronger El Nino floods occurred before 123 kyr BP and El Ninos were weaker during the second half of MIS 5e. The change to weaker ENSO activity in Peru is therewith roughly contemporaneous with the beginning cooling in Greenland.

    The public health nurses’ scope of practice explicitly includes child protection within their role, which places them in a prime position to identify child protection concerns. This role compliments that of other professions and voluntary agenices who work with children. Public health nurses are in a privileged position as they form a relationship with the child’s parent(s)/guardian(s) and are able to see the child in its own environment, which many professionals cannot. Child protection in Ireland, while influenced by other countries, has progressed through a distinct pathway that streamlined protocols and procedures. However, despite the above serious failures have occurred in the Irish system, and inquiries over the past 20 years persistently present similar contributing factors, namely, the lack of standardized and comprehensive service responses. Moreover, poor practice is compounded by the lack of recognition of the various interactional processes taking place within and between the different agencies of child protection, leading to psychological barriers in communication. This article will explore the lessons learned for public health nurses practice in safeguarding children in the Republic of Ireland. PMID:27335944

    1999-08-01

    We report high-performance lattice-matched GaInAsSb/GaSb thermophotovoltaic (TPV) devices with a 0.5 eV band gap. The TPV structures were grown on GaSb substrates by organometallic vapor phase epitaxy at a lower temperature (525 {degree}C compared to 550 {degree}C) to improve the quality of the metastable GaInAsSb alloy. The 0.5 eV TPV devices exhibit external quantum efficiency as high as 60{percent}, which corresponds to an internal quantum efficiency of 90{percent}, assuming 35{percent} reflection losses. This efficiency is comparable to the value measured for 0.53 eV devices. The ratio of the open circuit voltage to band-gap energy ratio decreases from 0.57 for 0.53 eV devices to 0.48 for 0.5 eV devices. {copyright} {ital 1999 American Institute of Physics.}

  13. What Is Inside A Lesson Learned?

    NASA Astrophysics Data System (ADS)

    Scheer, S.

    2009-04-01

    The learning of lessons is something that is inherent to normal human behavior. All kind of human interaction experiences critical inspection after a severe or even disastrous event has occurred. Particular inspections have been undertaken in the field of natural disasters. Hence human risk management can continuously be improved according to lessons learned from previous disasters or with the outcome of experience shared with other stakeholders in that field. This paper shows the results of a lessons learned project over the past years: the NEDIES (Natural and Environmental Information Exchange System) deals with lessons learned during the classical risk management phases of prevention, preparedness and response At first glance a lesson is just pure text. Basically it mirrors what has been experienced within a certain context. Having a closer look at a lesson one finds out that a lesson refers to a specific emergency-triggering situation. A situation is more than a simple reference to a hazard: a "rapidly rising lake level" could have more meaning than "a flood". In order to take out positive information it is advisable not only to list up all potential benefits that could be drawn from a lesson; the explicit mentioning of benefits could be helpful in order to prepare further actions beforehand. Moreover one should also consider possible actions to take if that particular situation of the lesson exhibits again or elsewhere. In the case of rapidly rising lake level an a-priori prioritization of response actions could be done. The description of the situation is linked with other characteristics of the lesson; local issues as well as historical considerations can play a role. A flood in a densely populated town can produce different implications than a flood in the countryside. The benefits of the lesson and actions proposed could be linked with experiences made in the past. Other issues concern people involved: the addressees. Typical addressees are local decision

  14. Lessons from dragonfly flight

    NASA Astrophysics Data System (ADS)

    Wang, Z. Jane

    2005-11-01

    I will describe two lessons we learned from analyzing dragonfly flight using computers and table-top experiments. Part I: The role of drag in insect flight. Airplanes and helicopters are airborne via aerodynamic lift, not drag. However, it is not a priori clear that insects use only lift to fly. We find that dragonfly uses mainly drag to hover, which explains an anomalous factor of four in previous estimates of dragonfly lift coefficients, where drag was assumed to be negligible. Moreover, we show that the use of drag for flight is efficient at insect size. This suggests a re-consideration of the hovering efficiency of flapping flight, which is no longer described by the lift to drag ratio. Part II. Fore-hind wing interaction in dragonfly flight. A distinctive feature of dragonflies is their use of two pairs of wings which are driven by separate direct muscles. Dragonflies can actively modulate the phase delay between fore-hind wings during different maneuver. We compute the Navier-Stokes equation around two wings following the motion measured from our tethered dragonfly experiments, and find an explanation of the advantage of counter-stroking during hovering.

  15. Best Practices for Researching and Documenting Lessons Learned

    NASA Technical Reports Server (NTRS)

    Goodman, John L.

    2007-01-01

    Identification, resolution, and avoidance of technical and programmatic issues are important for ensuring safe and successful space missions. Although the importance of applying lessons learned to reduce risk is frequently stressed, there is little material available to help technical and management personnel research and document lessons learned. Collecting, researching, identifying, and documenting lessons learned that will be useful to current and future management and engineering personnel is not always a straightforward task. This white paper presents lessons learned and best practices concerning the research and documentation of technical and organizational lessons learned. It is intended to enable organizations to initiate or improve lessons learned research and documentation efforts. The content of this white paper is based on four technical lessons learned projects conducted by the United Space Alliance (USA) Flight Design and Dynamics Department, in support of the NASA/JSC Flight Design and Dynamics Division. Each project published a report, titled as follows: GPS Lessons Learned From the ISS, Space Shuttle and X-38; Lessons Learned From Seven Space Shuttle Missions; Space Shuttle Rendezvous and Proximity Operations Experience Report; and Navigation Technical History with Lessons Learned. The four projects were different in availability of subject matter experts and primary source material, subject scope, and the level of effort required to produce the final report. However, generic lessons can be drawn from all of them. The best practices will be discussed by the phases of report research and development: Defining Report Requirements, Project Organization, and Schedule, Collection and Analysis of Source Material, Writing and Integrating the Report, and Review and Revision of the Report.

  18. Phosphatidylinositol phosphate kinase PIPKIγ and phosphatase INPP5E coordinate initiation of ciliogenesis.

    PubMed

    Xu, Qingwen; Zhang, Yuxia; Wei, Qing; Huang, Yan; Hu, Jinghua; Ling, Kun

    2016-01-01

    Defective primary cilia are causative to a wide spectrum of human genetic disorders, termed ciliopathies. Although the regulation of ciliogenesis is intensively studied, how it is initiated remains unclear. Here we show that type Iγ phosphatidylinositol 4-phosphate (PtdIns(4)P) 5-kinase (PIPKIγ) and inositol polyphosphate-5-phosphatase E (INPP5E), a Joubert syndrome protein, localize to the centrosome and coordinate the initiation of ciliogenesis. PIPKIγ counteracts INPP5E in regulating tau-tubulin kinase-2 (TTBK2) recruitment to the basal body, which promotes the removal of microtubule capping protein CP110 and the subsequent axoneme elongation. Interestingly, INPP5E and its product-PtdIns(4)P-accumulate at the centrosome/basal body in non-ciliated, but not ciliated, cells. PtdIns(4)P binding to TTBK2 and the distal appendage protein CEP164 compromises the TTBK2-CEP164 interaction and inhibits the recruitment of TTBK2. Our results reveal that PtdIns(4)P homoeostasis, coordinated by PIPKIγ and INPP5E at the centrosome/ciliary base, is vital for ciliogenesis by regulating the CEP164-dependent recruitment of TTBK2.

    Joubert syndrome and related disorders (JSRD) are clinically and genetically heterogeneous ciliopathies sharing a peculiar midbrain–hindbrain malformation known as the ‘molar tooth sign'. To date, 19 causative genes have been identified, all coding for proteins of the primary cilium. There is clinical and genetic overlap with other ciliopathies, in particular with Meckel syndrome (MKS), that is allelic to JSRD at nine distinct loci. We previously identified the INPP5E gene as causative of JSRD in seven families linked to the JBTS1 locus, yet the phenotypic spectrum and prevalence of INPP5E mutations in JSRD and MKS remain largely unknown. To address this issue, we performed INPP5E mutation analysis in 483 probands, including 408 JSRD patients representative of all clinical subgroups and 75 MKS fetuses. We identified 12 different mutations in 17 probands from 11 JSRD families, with an overall 2.7% mutation frequency among JSRD. The most common clinical presentation among mutated families (7/11, 64%) was Joubert syndrome with ocular involvement (either progressive retinopathy and/or colobomas), while the remaining cases had pure JS. Kidney, liver and skeletal involvement were not observed. None of the MKS fetuses carried INPP5E mutations, indicating that the two ciliopathies are not allelic at this locus. PMID:23386033

    Background Over the last decade several phase III microbicides trials have been conducted in developing countries. However, laboratories in resource constrained settings do not always have the experience, infrastructure, and the capacity to deliver laboratory data meeting the high standards of clinical trials. This paper describes the design and outcomes of a laboratory quality assurance program which was implemented during a phase III clinical trial evaluating the efficacy of the candidate microbicide Cellulose Sulfate 6% (CS) [1]. Methodology In order to assess the effectiveness of CS for HIV and STI prevention, a phase III clinical trial was conducted in 5 sites: 3 in Africa and 2 in India. The trial sponsor identified an International Central Reference Laboratory (ICRL), responsible for the design and management of a quality assurance program, which would guarantee the reliability of laboratory data. The ICRL provided advice on the tests, assessed local laboratories, organized trainings, conducted supervision visits, performed re-tests, and prepared control panels. Local laboratories were provided with control panels for HIV rapid tests and Chlamydia trachomatis/Neisseria gonorrhoeae (CT/NG) amplification technique. Aliquots from respective control panels were tested by local laboratories and were compared with results obtained at the ICRL. Results Overall, good results were observed. However, discordances between the ICRL and site laboratories were identified for HIV and CT/NG results. One particular site experienced difficulties with HIV rapid testing shortly after study initiation. At all sites, DNA contamination was identified as a cause of invalid CT/NG results. Both problems were timely detected and solved. Through immediate feedback, guidance and repeated training of laboratory staff, additional inaccuracies were prevented. Conclusions Quality control guidelines when applied in field laboratories ensured the reliability and validity of final study data

  4. PAP and NT5E inhibit nociceptive neurotransmission by rapidly hydrolyzing nucleotides to adenosine

    PubMed Central

    2011-01-01

    Background Prostatic acid phosphatase (PAP) and ecto-5'-nucleotidase (NT5E, CD73) produce extracellular adenosine from the nucleotide AMP in spinal nociceptive (pain-sensing) circuits; however, it is currently unknown if these are the main ectonucleotidases that generate adenosine or how rapidly they generate adenosine. Results We found that AMP hydrolysis, when measured histochemically, was nearly abolished in dorsal root ganglia (DRG) neurons and lamina II of spinal cord from Pap/Nt5e double knockout (dKO) mice. Likewise, the antinociceptive effects of AMP, when combined with nucleoside transport inhibitors (dipyridamole or 5-iodotubericidin), were reduced by 80-100% in dKO mice. In addition, we used fast scan cyclic voltammetry (FSCV) to measure adenosine production at subsecond resolution within lamina II. Adenosine was maximally produced within seconds from AMP in wild-type (WT) mice but production was reduced >50% in dKO mice, indicating PAP and NT5E rapidly generate adenosine in lamina II. Unexpectedly, we also detected spontaneous low frequency adenosine transients in lamina II with FSCV. Adenosine transients were of short duration (<2 s) and were reduced (>60%) in frequency in Pap-/-, Nt5e-/- and dKO mice, suggesting these ectonucleotidases rapidly hydrolyze endogenously released nucleotides to adenosine. Field potential recordings in lamina II and behavioral studies indicate that adenosine made by these enzymes acts through the adenosine A1 receptor to inhibit excitatory neurotransmission and nociception. Conclusions Collectively, our experiments indicate that PAP and NT5E are the main ectonucleotidases that generate adenosine in nociceptive circuits and indicate these enzymes transform pulsatile or sustained nucleotide release into an inhibitory adenosinergic signal.

    The research on alternative toxicological methods provides, among other things, a privileged viewpoint on one of the central issues of modern biomedical research--the relationship between (a) biological phenomena observed at the level of tissues and organisms and (b) their cellular and molecular bases as studied in isolated systems in vitro. The newly released ToxCast Phase 1 results, subject to initial analysis, converge with evidence from other fields (e.g., research on drug design with intensive use of omics technologies, traditional research on alternative tests) in indicating a low degree of the in vitro/in vivo correlation overall. In addition, this and other approaches point to the need for combining biological and chemical information in exploring the in vitro to in vivo connection. PMID:21069615

    These twelve lessons, and an introductory lesson, are tutorials in basic topics of introductory chemistry. They are suitable for school use, individual study, or distance learning. They are particularly valuable as review material for students in more advanced courses who may have been away from the subject for some time. They contain a great variety of problems and exercises driven by random-number generators, so that the same problem never repeats exactly. The lessons are, for the most part, Socratic dialogues in which the student is required to answer questions and perform simulated experiments in order to discover chemical principles. They are organized in an intuitive chapter and page structure. One may move readily around each lesson. There are many on-screen facilities such as help, data tables, and a calculator.

    The idea that music makes you smarter has received considerable attention from scholars and the media. The present report is the first to test this hypothesis directly with random assignment of a large sample of children (N = 144) to two different types of music lessons (keyboard or voice) or to control groups that received drama lessons or no lessons. IQ was measured before and after the lessons. Compared with children in the control groups, children in the music groups exhibited greater increases in full-scale IQ. The effect was relatively small, but it generalized across IQ subtests, index scores, and a standardized measure of academic achievement. Unexpectedly, children in the drama group exhibited substantial pre- to post-test improvements in adaptive social behavior that were not evident in the music groups. PMID:15270994

    2014-08-01

    In comparison to other sectors of the marine system, the palaeoceanography of the subarctic North Pacific Ocean is poorly constrained. New diatom isotope records of δ13C, δ18O, δ30Si (δ13Cdiatom, δ18Odiatom, δ30Sidiatom), are presented alongside existing geochemical and isotope records to document changes in photic zone conditions, including nutrient supply and the efficiency of the soft-tissue biological pump, between Marine Isotope Stage (MIS) 4 and MIS 5e. Peaks in opal productivity in MIS 5b/c and MIS 5e are both associated with the breakdown of the regional halocline stratification and increased nutrient supply to the photic zone. Whereas the MIS 5e peak is associated with low rates of nutrient utilisation, the MIS 5b/c peak is associated with significantly higher rates of nutrient utilisation. Both peaks, together with other smaller increases in productivity in MIS 4 and 5a culminate with a~significant increase in freshwater input which strengthens/re-establishes the halocline and limits further upwelling of sub-surface waters to the photic zone. Whilst δ30Sidiatom and previously published records of diatom δ15N (δ15Ndiatom) (Brunelle et al., 2007, 2010) show similar trends until the latter half of MIS 5a, the records become anti-correlated after this juncture and into MIS 4, suggesting a possible change in photic zone state such as may occur with a shift to iron or silicon limitation.

    2013-09-01

    Paleoceanographic archives derived from 17 marine sediment cores reconstruct the response of the Southwest Pacific Ocean to the peak interglacial, Marine Isotope Stage (MIS) 5e (ca. 125 ka). Paleo-Sea Surface Temperature (SST) estimates were obtained from the Random Forest model—an ensemble decision tree tool—applied to core-top planktonic foraminiferal faunas calibrated to modern SSTs. The reconstructed geographic pattern of the SST anomaly (maximum SST between 120 and 132 ka minus mean modern SST) seems to indicate how MIS 5e conditions were generally warmer in the Southwest Pacific, especially in the western Tasman Sea where a strengthened East Australian Current (EAC) likely extended subtropical influence to ca. 45°S off Tasmania. In contrast, the eastern Tasman Sea may have had a modest cooling except around 45°S. The observed pattern resembles that developing under the present warming trend in the region. An increase in wind stress curl over the modern South Pacific is hypothesized to have spun-up the South Pacific Subtropical Gyre, with concurrent increase in subtropical flow in the western boundary currents that include the EAC. However, warmer temperatures along the Subtropical Front and Campbell Plateau to the south suggest that the relative influence of the boundary inflows to eastern New Zealand may have differed in MIS 5e, and these currents may have followed different paths compared to today.

    We studied the interaction between deoxynivalenol (DON)-feeding and a subsequent pre- and post-hepatic immune stimulus with the hypothesis that the liver differently mediates the acute phase reaction (APR) in pigs. Barrows (n = 44) were divided into a DON-(4.59 mg DON/kg feed) and a control-diet group, surgically equipped with permanent catheters pre- (V. portae hepatis) and post-hepatic (V. jugularis interna) and infused either with 0.9% NaCl or LPS (7.5 µg/kg BW). Thus, combination of diet (CON vs. DON) and infusion (CON vs. LPS, jugular vs. portal) created six groups: CON_CONjug.-CONpor., CON_CONjug.-LPSpor., CON_LPSjug.-CONpor., DON_CONjug.-CONpor., DON_CONjug.-LPSpor., DON_LPSjug.-CONpor.. Blood samples were taken at −30, 15, 30, 45, 60, 75, 90, 120, 150, 180 min relative to infusion and analyzed for leukocytes and TNF-alpha. Concurrently, clinical signs were scored and body temperature measured during the same period. LPS as such induced a dramatic rise in TNF-alpha (p < 0.001), hyperthermia (p < 0.01), and severe leukopenia (p < 0.001). In CON-fed pigs, an earlier return to physiological base levels was observed for the clinical complex, starting at 120 min post infusionem (p < 0.05) and persisting until 180 min. DON_LPSjug.-CONpor. resulted in a lower temperature rise (p = 0.08) compared to CON_LPSjug.-CONpor.. In conclusion, APR resulting from a post-hepatic immune stimulus was altered by chronic DON-feeding. PMID:26703732

  16. Last Interglacial (MIS5e) hydrographic shifts linked to meltwater discharges from the East Greenland margin

    NASA Astrophysics Data System (ADS)

    2016-04-01

    The East Greenland Current (EGC) plays a key role in transporting polar water from the Arctic to convectional sites of the Iceland and Labrador seas. Ongoing melting of the Greenland Ice Sheet (GIS) as well as the Arctic sea ice prompts freshening of the EGC and accumulation of low-density water in the subpolar North Atlantic, thus affecting the stabilities of water mass overturning and subsequent northward heat transfer. To assess natural eastern GIS dynamics and possible freshwater-induced regional oceanic reorganizations we analyzed several sediment sequences from the poorly investigated area along the eastern Greenland margin and the western Nordic Seas. Records span the last interglacial (LIG, MIS5e) cycle, including deglacial Termination 2 and the LIG climatic optimum. On a global scale, the latter is believed to have been warmer than present, with a higher sea level, and may, therefore, serve as a promising analogue for future hydrographic changes. Based on various proxy data (stable isotopes, planktic foraminiferal assemblages, ice-rafted debris) our reconstructions support the notion of a "two-step development" of Termination 2 which underwent severe surface freshening in the subpolar North Atlantic. This is shown in extremely light oxygen isotopic values registered all along the eastern Greenland margin during early MIS5e, which are indicative for pronounced eastern/central GIS retreat and a further propagation of the resulting meltwater southward via the EGC. In addition, we find compelling evidence for at least two separate meltwater episodes in proximity of the eastern GIS during early MIS5e. The climatic episode in between is correlated with an early LIG warm peak, which may be linked to enhanced presence of Atlantic water in the central Nordic Seas (Bauch et al., 2012) and further downstream along southern Greenland (Hillaire-Marcel et al., 1994, Irvali et al., 2012). Our data, therefore, reveal a complex and variable dynamic of the EGC during MIS5e

    1999-01-01

    COSS (Crew On-Orbit System Support) is changing. Designed as computer based in-flight refresher training, it is getting good reviews and the demands on the product can be expected to increase. Last year, the lessons were written using Authorware, which had a number of limitations. The most important one was that the navigation and the layout functions were both in one package that was not easy to learn. The lesson creator had to be good at both programming and design. There were also a number of other problems, as detailed in my report last year. This year the COSS unit made the switch to embrace modularity. The navigation function is handled by a player that was custom-written using Delphi. The layout pages are now standard HTML files that can be created using any number of products. This new system gives new flexibility and unties the process from one product (and one company). The player can be re-written by a programmer without affecting the lesson pages. It is also now possible for anybody with a word-processor to make part of the HTML lesson pages and to use many of the new commercially available tools that are being designed for web pages. This summer I created a computer-based training (CBT) lesson on the IBM ThinkPad 760 ED and 760XD laptop computers that should fly on the International Space Station. I also examined the COSS system, the new player and the other new software products.

    Exposures of MoS2 to 1.5-eV atomic oxygen in an anhydrous environment reveal that the degree of oxidation is essentially independent of crystallite orientation, and that the surface-adsorbed reaction products are MoO3 and MoO2. A mixture of oxides and sulfide exists over a depth of about 90 A, and this layer has a low diffusion rate for oxygen. It is concluded that a protective oxide layer forms on MoS2 on exposure to the atomic-oxygen-rich environment of LEO.

  6. Regional differences in interglacial climate expression: A revisit to MIS 5e

    NASA Astrophysics Data System (ADS)

    Bauch, H. A.

    2015-12-01

    Reconstructions of air and surface ocean temperatures of the Eemian interglacial (MIS5e) often infer higher values than those of the Holocene, with a recently estimated global sea level 6-9m meters above the present highstand. Many a study also have reported on Eemian climate instability with respect to both variability in temperatures and sea level. These variabilities are often explained by AMOC changes and by invoking massive bi-polar ice sheet losses. In spite of recent sea-level compilation studies on such fluctuations during the last interglacial using coral evidence, the questions remain how, where, and, notably, when could a rapid ice growth have occurred during the otherwise so warm but relatively short Eemian full-interglacial period? Ocean field data now indicate a relatively cool polar North Atlantic for a substantial part of the post-deglacial (T2) interval, whereas in the subpolar region ocean temperature peaked directly after T2 together with high insolation. Thus, based on circumstantial evidence significant glacier ice must have remained at sea-level along the polar periphery for rather long. In addition with other proxy data the overall sequence of events would therefore dictate a late global sea-level highstand during MIS5e.

    Last Intergalcial in the island of Mallorca (NW Mediterranean) have been the subject of research since the early 60's (Butzer & Cuerda 1960). Despite both the location and stratigraphy of MIS 5e outcrops in the island are well known, the elevation of relative sea level (RSL) markers around the island has never been measured with high-accuracy topographic techniques (e.g. DGPS) and the interpretation of the paleo RSL has never been carried out using standardized definition of the indicative meaning of each RSL marker. In this study we present the results of two field trips aimed at measuring last interglacial deposits in Mallorca with high-accuracy GPS and at establishing, surveying modern shorelines as analogs, indicative ranges and reference water level values for RSL markers across the island. Using an earth-ice coupled GIA-model we performed several model-runs for investigating isostatic adjustment since MIS 5e in the island. These results are compared with the elevation of our deposits in the field and discussed in terms of tectonics and eustasy.

    2013-01-01

    The assimilation of lessons from the past is an essential component of education for scientists of tomorrow. These lessons are not easy to find. History books on science are few and usually highly dramatized and biographies of scientists tend to exaggerate the pomp of scientific discovery. Both underplay the hard and laborious work that is integral to any scientific pursuit. Here we illustrate one such example. A century ago, the Nobel Prize in Medicine was awarded to two scientists: Ilya Metchnikoff, a Russian zoologist, for the discovery ofphagocytosis-a cell-mediated ingestion ofmicrobes; and Paul Ehrlich, a distinguished physician-scientist, for discovering a highly antigen-specific serum-derived antibody-based immune defense. These two diametrically opposing views of the host-pathogen interaction set the stage for a strife that led to seminal advancements in immunology. Mirrored in this journey are important lessons for scientists today--ubiquitously as applicable to modern scientific life as they were a century ago. This commentaryhighlights these lessons--a fitting centenary to a well-deserved recognition. PMID:23427369

    Krok, Michelle; Cool, A.; Tanner, K. D.; Prather, E.

    2010-01-01

    Employing the research-based curricular planning approach called the 5E Model (Engage, Explore, Explain, Elaborate, Evaluate), we developed five planetarium-based labs for non-science majors to teach students how to predict the apparent motions of the Sun, Moon, and stars from different positions on Earth. Our goal was to determine the effectiveness of the curriculum's ability to foster conceptual change over the course of a semester for two classes (N 33). We also assessed student confidence and interest. Open-ended responses preceded by a multiple choice question were used to assess student content knowledge before and after each laboratory. We found positive shifts for 13 out of the 15 assessments (86%) based on quantitative analysis of the closed-ended responses. Qualitative results will be presented as a result of analysis on the open-ended responses.

    An experimental effort to characterize an existing 5-eV neutral atomic oxygen beam facility being developed at Princeton Plasma Physics Laboratory is described. This characterization effort includes atomic oxygen flux and flux distribution measurements using a catalytic probe, energy determination using a commercially designed quadrupole mass spectrometer (QMS), and the exposure of oxygen-sensitive materials in this beam facility. Also, comparisons were drawn between the reaction efficiencies of materials exposed in plasma ashers, and the reaction efficiencies previously estimated from space flight experiments. The results of this study show that the beam facility is capable of producing a directional beam of neutral atomic oxygen atoms with the needed flux and energy to simulate low Earth orbit (LEO) conditions for real time accelerated testing. The flux distribution in this facility is uniform to +/- 6 percent of the peak flux over a beam diameter of 6 cm.

  17. Natural Disasters: What Is Inside A Lesson Learned?

    NASA Astrophysics Data System (ADS)

    Scheer, S.

    2009-04-01

    The learning of lessons is something that is inherent to normal human behavior. All kind of human interaction experiences critical inspection after a severe or even disastrous event has occurred. Particular inspections have been undertaken in the field of natural disasters. Hence human risk management can continuously be improved according to lessons learned from previous disasters or with the outcome of experience shared with other stakeholders in that field. This paper shows the results of a lessons learned project over the past years: the NEDIES (Natural and Environmental Information Exchange System) deals with lessons learned during the classical risk management phases of prevention, preparedness and response At first glance a lesson is just pure text. Basically it mirrors what has been experienced within a certain context. Having a closer look at a lesson one finds out that a lesson refers to a specific emergency-triggering situation. A situation is more than a simple reference to a hazard: a "rapidly rising lake level" could have more meaning than "a flood". In order to take out positive information it is advisable not only to list up all potential benefits that could be drawn from a lesson; the explicit mentioning of benefits could be helpful in order to prepare further actions beforehand. Moreover one should also consider possible actions to take if that particular situation of the lesson exhibits again or elsewhere. In the case of rapidly rising lake level an a-priori prioritization of response actions could be done. The description of the situation is linked with other characteristics of the lesson; local issues as well as historical considerations can play a role. A flood in a densely populated town can produce different implications than a flood in the countryside. The benefits of the lesson and actions proposed could be linked with experiences made in the past. Other issues concern people involved: the addressees. Typical addressees are local decision

    2011-01-01

    Planning products and procedures that allow the mission flight control teams and the astronaut crews to plan, train and fly every Space Shuttle mission have been developed by the Flight Planning Branch at the NASA Johnson Space Center. As the Space Shuttle Program ends, lessons learned have been collected from each phase of the successful execution of these Shuttle missions. Specific examples of how roles and responsibilities of console positions that develop the crew and vehicle attitude timelines will be discussed, as well as techniques and methods used to solve complex spacecraft and instrument orientation problems. Additionally, the relationships and procedural hurdles experienced through international collaboration have molded operations. These facets will be explored and related to current and future operations with the International Space Station and future vehicles. Along with these important aspects, the evolution of technology and continual improvement of data transfer tools between the shuttle and ground team has also defined specific lessons used in the improving the control teams effectiveness. Methodologies to communicate and transmit messages, images, and files from Mission Control to the Orbiter evolved over several years. These lessons have been vital in shaping the effectiveness of safe and successful mission planning that have been applied to current mission planning work in addition to being incorporated into future space flight planning. The critical lessons from all aspects of previous plan, train, and fly phases of shuttle flight missions are not only documented in this paper, but are also discussed as how they pertain to changes in process and consideration for future space flight planning.

    Since 2005, graduate students in the Brown University Department of Earth, Environmental, and Planetary Studies have volunteered to teach science to second-grade students at Vartan Gregorian Elementary School in Providence, RI. Initially developed to bring science into classrooms where it was not explicitly included in the curriculum, the graduate student-run program today incorporates the Providence Public Schools Grade 2 science curriculum into weekly, interactive sessions that engage the students in hypothesis-driven science. We will describe the program structure, its integration into the Providence Public Schools curriculum, and 3 example lessons relevant to geology. Lessons are structured to develop the students' ability to share and incorporate others' ideas through written and oral communication. The volunteers explain the basics of the topic and engage the students with introductory questions. The students use this knowledge to develop a hypothesis about the upcoming experiment, recording it in their "Science Notebooks." The students record their observations during the demonstration and discuss the results as a group. The process culminates in the students using their own words to summarize what they learned. Activities of particular interest to educators in geoscience are called "Volcanoes!", "The "Liquid Race," and "Phases of the Moon." The "Volcanoes!" lesson explores explosive vs. effusive volcanism using two simulated volcanoes: one explosive, using Mentos and Diet Coke, and one effusive, using vinegar and baking soda (in model volcanoes that the students construct in teams). In "Liquid Race," which explores viscosity and can be integrated into the "Volcanoes!" lesson, the students connect viscosity to flow speed by racing liquids down a ramp. "Phases of the Moon" teaches the students why the Moon has phases, using ball and stick models, and the terminology of the lunar phases using cream-filled cookies (e.g., Oreos). These lessons, among many others

    2004 Sumatra earthquakes caused a devastating tsunami and cost the lives of nearly 260,000 people in the South Asian region. These earthquakes and associated tsunami are sourced from convergence of the Indo-Australian and Asian Plates. In the eastern part of this plate boundary the Australian continent is colliding with Asia. The first turbiditic sand in Timor island was around 5 Ma and the collision propagated to the southwestern until ~2 Ma. But the activities of the neighborhood of the Timor island in the Quaternary or the Holocene is unknown. This study provides the new 230Th dates from the raised coral terraces at Kisar Island, eastern Indonesia. Eight fossil corals were measured by MC-ICP-MS at the National Taiwan University with permil-level precision. Two out of the eight samples having ~1.5 % calcite and acceptable δ234Uinitial showed robust ages of 123-121 ka. Another three open-system model ages were from 125-119 ka by Thompson et al.'s method (2003). These different elevated fossil corals with ages of 125-119 ka favored the two-peak sea-level curve in MIS 5e explained by Chappell and Veeh (1978). New age results relocated the second peak should be about three thousand years earlier than their proposed 119 ka. A minimum uplift rate of 0.1 m/kyrs is derived from the highest-position fossil corals. The 230Th-dated fossils in the north coast of Timor-Leste suggest the MIS 5e terraces could reach 55 m high, hence a referable uplift rate of ~0.4 m/kyrs could be a maximum estimate. The uplift rate of 0.1-0.4 m/ka since late Pleistocene is well consistent with published values from Atauro Island and Timor-Leste in eastern Indonesia. Based on the uplift rate, the terraces in eastern Kisar, with elevation lower than 100 m, expectedly located at MIS 7, 9, or 11; while the higher western terraces ranged from MIS 9-15. Besides, no remanet of Holocene fringe reefs around Kisar Island also suggests a relatively low activity of tectonics, in agreement with the modern

    Smiley, J K; Young, M A; Flint, S J

    1990-01-01

    The intracellular location of the adenovirus type 5 E1B 55-kilodalton (kDa) protein, particularly the question of whether it is associated with nuclear pore complexes, was examined. Fractionation of adenovirus type 5-infected HeLa cell nuclei by an established procedure (N. Dwyer and G. Blobel, J. Cell. Biol. 70:581-591, 1976) yielded one population of E1B 55-kDa protein molecules released by digestion of nuclei with RNase A and a second population recovered in the pore complex-lamina fraction. Free and E1B 55-kDa protein-bound forms of the E4 34-kDa protein (P. Sarnow, C. A. Sullivan, and A. J. Levine, Virology 120:387-394, 1982) were largely recovered in the pore complex-lamina fraction. Nevertheless, the association of E1B 55-kDa protein molecules with this nuclear envelope fraction did not depend on interaction of the E1B 55-kDa protein with the E4 34-kDa protein. Comparison of the immunofluorescence patterns observed with antibodies recognizing the E1B 55-kDa protein or cellular pore complex proteins and of the behavior of these viral and cellular proteins during in situ fractionation suggests that the E1B 55-kDa protein does not become intimately or stably associated with pore complexes in adenovirus-infected cells.

    An atomic oxygen exposure facility has been developed for studies of material degradation. The goal of these studies is to provide design criteria and information for the manufacture of long life (20 to 30 years) construction materials for use in LEO. The studies that are being undertaken using the facility will provide: absolute reaction cross sections for use in engineering design problems; formulations of reaction mechanisms; and calibration of flight hardware (mass spectrometers, etc.) in order to directly relate experiments performed in LEO to ground based investigations. The facility consists of: (1) a CW laser sustained discharge source of O atoms having a variable energy up to 5 eV and an intensity between 10(15) and 10(17) O atoms s(-1) cm(-2); (2) an atomic beam formation and diagnostics system consisting of various stages of differential pumping, a mass spectrometer detector, and a time of flight analyzer; (3) a spinning rotor viscometer for absolute O atom flux measurements; and (4) provision for using the system for calibration of actual flight instruments. Surface analysis equipment is available for the characterization of material surfaces before and after exposure to O atoms.

    Hepatocellular carcinoma (HCC) is resistant to conventional chemotherapy. A few clinical trials have shown that the cytidine analogue gemcitabine appears to have antitumor activity for HCC, but the overall survival times remain to be improved. In this study, we examined the synergistic effect of adenovirus type 5 E1A (E1A) and gemcitabine on HCC and found that E1A sensitized J5, J7, Huh7, and HepG2 HCC cells to gemcitabine. To further study the E1A-mediated chemosensitization, we established stable cell lines that expressed the E1A gene and then examined whether E1A could have proapoptotic activity while expressed in HCC cells. Our results clearly showed that E1A sensitized HCC cells to gemcitabine through induction of apoptosis. To study the underlying mechanism, we tested nuclear factor (NF)-kappaB activity and found that NF-kappaB was activated in HCC cells treated with gemcitabine but not in HCC cells that expressed E1A. Occurrence of apoptosis entails cleavage of poly (ADP-ribose) polymerase (PARP), a nuclear protein involved in DNA repair, genome stability, and maintenance of telomere length. Our study showed that gemcitabine enhanced PARP expression. However, E1A did not induce PARP cleavage but rather suppressed PARP expression at the transcriptional level. Further study showed that both NF-kappaB and PARP played protective roles in the prevention of E1A+gemcitabine-induced apoptosis. PMID:14559808

    Lesson plans in surgery enable trainers and trainees to agree on goals that balance training needs with service commitments. Lesson plans are individualised to the trainee and encourage ownership of learning. They are based on SMART criteria and therefore have a sound educational footing. Most of the work in creating a lesson plan falls to the trainee. The total time for creation of each plan is approximately 20 min. Our use of lesson plans for surgical training has been met with favourable response from both trainer and trainees. PMID:17550516

    Sedimentologic, stratigraphic, and geochronologic analyses of a previously undescribed carbonate section on Oahu, Hawaii, provide new evidence for two distinct sea-level highstands on Oahu during the last interglacial period (oxygen isotope substage 5e). Whereas electron-spin-resonance and uranium-series ages (122 ±8 ka to 152 ±25 ka, and 115 ±10 ka to 160 ±15 ka, respectively) of in situ corals place the age of the deposits within substage 5e, it is the unique sequence of strata found in these exposures that reveals the two transgressions. A highstand lagoonal deposit of coral-algal bafflestone is overlain by large seaward-dipping slabs of beach-rock. The beachrock, deposited during a mid-5e regression, is in turn overlain by a second highstand lagoonal deposit. This sequence was deposited in a broad, shallow, back-reef embayment that was very sensitive to fluctuations in sea level. Elsewhere, along much of the shoreline of Oahu, an in situ coral-algal framestone (Waimanalo Formation), representing the initial 5e highstand, is erosionally truncated on its upper surface. This erosional unconformity represents the mid-5e lowstand and separates the framestone from overlying, seaward-dipping, planar-bedded grainstone and rudstone (Leahi Formation) that accumulated during the second 5e highstand.

    Previous observations that the adenovirus type 5 (Ad5) E4orf6 and E4orf3 gene products have redundant effects in viral lytic infection together with the recent findings that E4orf6 possesses transforming potential prompted us to investigate the effect of E4orf3 expression on the transformation of primary rat cells in combination with adenovirus E1 oncogene products. Our results demonstrate for the first time that E4orf3 can cooperate with adenovirus E1A and E1A plus E1B proteins to transform primary baby rat kidney cells, acting synergistically with E4orf6 in the presence of E1B gene products. Transformed rat cells expressing E4orf3 exhibit morphological alterations, higher growth rates and saturation densities, and increased tumorigenicity compared with transformants expressing E1 proteins only. Consistent with previous results for adenovirus-infected cells, the E4orf3 protein is immunologically restricted to discrete nuclear structures known as PML oncogenic domains (PODs) in transformed rat cells. As opposed to E4orf6, the ability of E4orf3 to promote oncogenic cell growth is probably not linked to a modulation of p53 functions and stability. Instead, our results indicate that the transforming activities of E4orf3 are due to combinatorial effects that involve the binding to the adenovirus 55-kDa E1B protein and the colocalization with PODs independent from interactions with the PML gene product. These data fit well with a model in which the reorganization of PODs may trigger a cascade of processes that cause uncontrolled cell proliferation and neoplastic growth. In sum, our results provide strong evidence for the idea that interactions with PODs by viral proteins are linked to oncogenic transformation. PMID:9882365

    On UT 2009 January 16, we observed a white light megaflare on the dM4.5e star YZ CMi as part of a long-term spectroscopic flare-monitoring campaign to constrain the spectral shape of optical flare continuum emission. Simultaneous U-band photometric and 3350-9260 A spectroscopic observations were obtained during 1.3 hr of the flare decay. The event persisted for more than 7 hr and at flare peak, the U-band flux was almost 6 mag brighter than in the quiescent state. The properties of this flare mark it as one of the most energetic and longest-lasting white light flares ever to be observed on an isolated low-mass star. We present the U-band flare energetics and a flare continuum analysis. For the first time, we show convincingly with spectra that the shape of the blue continuum from 3350 A to 4800 A can be represented as a sum of two components: a Balmer continuum as predicted by the Allred et al. radiative hydrodynamic flare models and a T{approx} 10,000 K blackbody emission component as suggested by many previous studies of the broadband colors and spectral distributions of flares. The areal coverage of the Balmer continuum and blackbody emission regions vary during the flare decay, with the Balmer continuum emitting region always being significantly ({approx}3-16 times) larger. These data will provide critical constraints for understanding the physics underlying the mysterious blue continuum radiation in stellar flares.

  11. High lake levels at Siling Co, central Tibet, during MIS 5e - 6

    Flights of well-preserved paleoshorelines around lakes atop the Tibetan plateau reflect paleoclimatic conditions in this highest region in the world and provide important constraints on the history of hydrologic change. Regionally, previous studies have shown that many Tibetan lakes achieved highstand levels during the Late Pleistocene - Early Holocene transition. Whether similar extents were reached in the geologic past, however, remains uncertain due to sparse dating of ancient shoreline features. Here we focus on exposures of relict, high shorelines around Siling Co, in central Tibet. Previous study of a well-preserved sequence of shorelines suggest that lake levels during the Late Pleistocene - Early Holocene reached ~ 64 m above present lake level (referenced to 1976). We determined ages of even higher shorelines (up to ~76 m above present lake level) using a combination of U-series dating of tufa deposits, 36Cl depth profiles of beach ridges, and optically stimulated luminescence (OSL) of beach sand. We obtained a 36Cl depth profile age of 113 ka from a tombolo in central peninsula of Siling Co, 66 m above present level; an OSL age from this deposit, however, yielded an age of ~ 43 ka and probably reflects saturation of the OSL signal. U-Th ages of tufa deposits range from 145 - 159 ka and place minimum constraints on lake levels during MIS 6 of 65 - 76 m above present level. Finally, an even older 36Cl age of 178 ka was obtained from a high spit shoreline (~ 62 m above present level). Collectively, our results provide evidence that lake levels at Siling Co reached or exceeded the Early Holocene highstand during the MIS 5e (Eemian) interglacial, suggesting that paleohydrologic conditions were similar during these time periods. Moreover, the preservation of higher shorelines developed during MIS 6 suggest the presence of an even larger lake during the penultimate glacial stage.

    Abstract: At the 2005 INMM/ESARDA Workshop in Santa Fe, New Mexico, I presented a paper entitled “Changing the Safeguards Culture: Broader Perspectives and Challenges.” That paper described a set of theoretical models that can be used as a basis for evaluating changes to safeguards culture. This paper builds on that theoretical discussion to address practical methods for influencing culture. It takes lessons from methods used to influence change in safety culture and security culture, and examines the applicability of these lessons to changing safeguards culture. Paper: At the 2005 INMM/ESARDA Workshop on “Changing the Safeguards Culture: Broader Perspectives and Challenges,” in Santa Fe, New Mexico, I presented a paper entitled “Changing the Safeguards Culture: Broader Perspectives and Challenges.” That paper, coauthored by Karyn R. Durbin and Andrew Van Duzer, described a set of theoretical models that can be used as a basis for evaluating changes to safeguards culture. This paper updates that theoretical discussion, and seeks to address practical methods for influencing culture. It takes lessons from methods used to influence change in safety culture and security culture, and examines the applicability of these lessons to changing safeguards culture. Implicit in this discussion is an understanding that improving a culture is not an end in itself, but is one method of improving the underlying discipline, that is safety, security, or safeguards. Culture can be defined as a way of life, or general customs and beliefs of a particular group of people at a particular time. There are internationally accepted definitions of safety culture and nuclear security culture. As yet, there is no official agreed upon definition of safeguards culture. At the end of the paper I will propose my definition. At the Santa Fe Workshop the summary by the Co-Chairs of Working Group 1, “The Further Evolution of Safeguards,” noted: “It is clear that ‘safeguards culture

    1994-03-01

    FRMAC-93 simulated a radiological accident at the Fort Calhoun nuclear power plant, 25 miles north of Omaha, Nebraska. The exercise involved the state Iowa and Nebraska, NRC as the lead Federal agency, FRMAC (Federal Radiological Monitoring and Assessment Center), and several federal agencies with statutory emergency responsibility. FRMAC-93 was a major 2-day field exercise designed to determine the effectiveness, coordination, and operations of a DOE-managed FRMAC. Other objectives were to ensure that appropriate priorities were established and assistance was provided to the states and the lead Federal agency by FRMAC. Day 1 involved the Fort Calhoun evaluated plume phase exercise. On Day 2, the flow of data, which was slow initially, improved so that confidence of states and other federal responders in FRMAC support capabilities was high. The impact and lessons learned from FRMAC-93 provided the necessary impetus to make organizational and operational changes to the FRMAC program, which were put into effect in the DOE exercise FREMONT at Hanford 3 months later.

    Global geodesy has improved dramatically over the past decade starting with the GPS for IERS and Geodynamics demonstration campaign in 1991 (GIG 91). At the time it took over a week of CPU time to process a network solution based on 21 global receivers and orbit overlaps were in the 40 cm range. Today it is possible to process a network solution based on 80 global receivers in less then one day of CPU time and orbit overlaps are in the 4 cm range. Special methods are under development for efficient processing of increasingly large regional networks which may contain hundreds or thousands of GPS receivers. Along the way there have been many lessons learned about GPS satellites, receivers, monuments, antennas, radomes, analysis, reference frames, error sources, and interpretation. A wide range of scientific disciplines have been impacted including studies of plate motion, post-glacial rebound, seasonal loading, deformation in plate boundary zones, coseismic displacements due to major earthquakes, postseiemic relaxation, and interseismic strain accumulation related to assessment of seismic hazards. Lessons learned will be presented in the context of new dense networks such as the Plate Boundary Observation (PBO).

Their structures were studied by IR and multinuclear NMR spectroscopy, and single crystal X-ray diffraction. The X-ray analysis revealed the presence of monoprotonated piperidinium cation in 1 and triprotonated cations in 2 and 3. The hexafluoro(μ-hydroxo)diborate anion was found in the mixed-anionic salts 2A and 2B which differ by the ratio of the anions. The extended hydrogen-bonded system is registered in all compounds. Static first order hyperpolarizabilities for the neutral ( 3E, 5E)-3,5-bis[4-(dimethylamino)benzylidene]-piperidin-4-one and its positively charged derivatives along with their molecular geometries and binding energy of 1 were calculated using DFT approach.

    γ Cas is the prototypical classical B0.5e star and is now known to be the primary in a wide binary system. It has long been famous for its unique hard X-ray characteristics, among which are variations that correlate with changes in a number of optical light and UV line and continuum properties. These peculiarities have led to a picture in which processes on or near the Be star produce the observed X-ray emission. In this paper we report on a 53 ks Chandra High Energy Transmission Grating Spectrometer observation of this target. An inspection of our spectrum shows that it is quite atypical for a massive star. The emission lines appear weak because of a strong short-wavelength continuum that arises from a hot plasma with kT=11-12 keV. The spectrum exhibits many lines, the strongest of which are Lyα features of H-like species from Fe through the even-Z intermediate elements (S, Si, Mg, and Ne), down to O and N. Line ratios of the ``rif triplet'' for a variety of He-like ions and of Fe XVII are consistent with the dominance of collisional atomic processes. However, the presence of Fe and Si fluorescence K features indicates that photoionization also occurs in nearby cold gas. The line profiles indicate a mean velocity at rest with an rms line broadening of 500 km s-1 and little or no asymmetry. An empirical global-fitting analysis of the line and continuum spectrum suggests that there are actually three or four plasma emission components. The first is the dominant hot (12 keV) component, of which some fraction (10%-30%) is heavily absorbed, while the remainder is affected by a much lower column density of only 3×1021 cm-2. The hot component has a Fe abundance of only 0.22+/-0.05 solar. The other two or three major emission components are ``warm'' and are responsible for most other emission lines. These components are dominated by plasma having temperatures near 0.1, 0.4, and 3 keV. Altogether, the warm components have an emission measure of about 14% of the hot

    A silicon wafer has been oxidized at room temperature in vacuum using a pure, ground-state beam of O(-) ions. The beam was of sufficiently low energy that no displacement damage or implantation was energetically possible. The resulting SiO2 films were analyzed with X-ray photoelectron spectroscopy. A logarithmic dependence of oxide thickness on dose was observed, with an extrapolated oxidation efficiency of unity for the clean silicon surface. A distinct initial oxidation phase was observed, with an anomalously high level of silicon suboxides. In addition, the valence-band offset between the silicon and the oxide was unusually small, suggesting a large interfacial dipole.

    Lesson "Balance in Nature" This simulation game-lesson (Balance in Nature) gives an opportunity for the students to show creativity, work independently, and to create models and ideas. It creates future-oriented thought connected to their experience, allowing them to propose solutions for global problems and personal responsibility for their activities. The class is divided in two teams. Each team chooses questions. 1. Question: Pollution in the environment. 2. Question: Care for nature and climate. The teams work on the chosen tasks. They make drafts, notes and formulate their solutions on small pieces of paper, explaining the impact on nature and society. They express their points of view using many different opinions. This generates alternative thoughts and results in creative solutions. With the new knowledge and positive behaviour defined, everybody realizes that they can do something positive towards nature and climate problems and the importance of individuals for solving global problems is evident. Our main goal is to recover the ecological balance, and everybody explains his or her own well-grounded opinions. In this work process the students obtain knowledge, skills and more responsible behaviour. This process, based on his or her own experience, dialogue and teamwork, helps the participant's self-development. Making the model "human↔ nature" expresses how human activities impact the natural Earth and how these impacts in turn affect society. Taking personal responsibility, we can reduce global warming and help the Earth. By helping nature we help ourselves. Teacher: Veselina Boycheva-Chapanova " Saint Patriarch Evtimii" Scholl Str.

    Changes in ocean circulation and climate are linked on orbital to millennial time-scales. We describe results of stable isotope and total carbonate analyses in cores collected within a sediment wave field on Gardar Drift 946 km south of Iceland. Two jumbo piston cores (JPCs) collected from either side of a km-scale migrating mudwave during Knorr cruise 166-14 were sampled at a down-core spacing of 5cm, yielding a resolution of ~ 600yr. We use % CaCO3, δ18O and magnetic susceptibility to correlate events from cores JPC 9 and JPC 11 (2720 and 2707 m water depth, respectively). We were able to confidently correlate between the cores down to Marine Isotope Stage (MIS) 5e. Using this technique of mudwave analysis, much can be inferred about current strength and direction around the Gardar Drift and deep North Atlantic Circulation. During MIS 5e (120 - 110 kyr), both core locations accumulated sediment at a nearly identical rate of ~ 30 cm/ kyr, indicating a uniform, laminar flow regime over the undulating seafloor topography. However, immediately following MIS 5e, the average sedimentation rates from both cores decreased dramatically. For the last 110 kyrs, JPC 11 (up-current side of the mudwave) accreted at ~ 11 cm/kyr. At JPC 9 (down-current side), sediments accreted at only ~ 8 cm/kyr. While these sedimentation rates varied over time, the ratio of sedimentation rates of JPC 9 to JPC 11 remained ~ 70% throughout the last 110 kyr. This preferential accretion has continued to the present day and indicates a classic migrating mudwave in a uniform flow regime (Flood, 1988). The stark contrast between the 5e and post-5e flow regimes indicates a large-scale reorganization of currents at ~ 110 kyr. The post-5e regime remained constant over the last ~ 110 kyr, indicating little variation in sediment source, current strength and/or current direction. Previous paleoceanographic research suggests strong glacial-interglacial variability in deep water formation as water mass

    The previous research showed that the teachers of the fourth grade at elementary school in West Sumatra need lesson plan and teaching materials which integrated with character education especially on mathematics subject. Teachers need teaching materials which encompasses the daily life problems (contextual) so that, it can increase students' understanding of mathematics. Realistic mathematics education is a solution to these problems. The aims of the research are to develop learning equipment, i. e lesson plan sand valid worksheets. Development model referred to the Plomp development model which consists of three phase namely preliminary research, prototyping phase, and assessment phase. However, in this research, it is only presented the results in the expert review which is in the part of prototyping phase. The instrument was the validation worksheet. Expert stated that each of lesson plan and students' worksheet were in valid criterion

  19. Multi-proxy insights into last interglacial (MIS 5e) conditions in the southern Labrador Sea: Consistencies and inconsistencies

    2013-04-01

    Last interglacial (Marine Isotopic Stage or MIS 5e) sediments from the Gloria Drift in the southernmost Labrador Sea (Core HU91-045-91; 53.33N 45.26W) were studied for their dinoflagellate cyst (dinocyst) content and their planktic foraminiferal assemblages and isotopic compositions. While both microfossil groups clearly reveal the occurrence of typical interglacial conditions in the area, they also reflect a slightly different evolution of the MIS 5e surface water conditions. The dinocyst assemblages are dominated by the cold-temperate species Nematosphaeropsis labyrinthus, with the secondary assemblages being composed by temperate oceanic Impagidinium species and the cosmopolitan species Operculodinium centrocarpum. The latter species shows a steady increase during the first half of MIS 5e, mirrored by a gradual decline of the polar planktic foraminifer Neogloboquadrina pachyderma (s). Still, reconstructed temperatures from the application of the modern analogue technique for this interval are fairly stable, albeit that those reconstructed from the dinocyst assemblages (~10 and 17 °C for winter and summer, respectively) exceed those reconstructed from the planktic foraminiferal assemblages (~5.5 and 9.5 °C) as well as modern values (~5.5 and 10.6 °C) by several degrees. This apparent inconsistency might be partly explained by distinct conditions within the respective water depth habitats of these micro-organisms, but other factors likely intervened, such as an offset in their respective seasonal production time and/or mixing of the fossil assemblages through advection from slightly distinct production areas. The early MIS 5e trend ended abruptly with a marked event characterized by a peak of Turborotalita quinqueloba, the quasi-disappearance of dinocysts, and a divergent shift of the stable oxygen isotope values in the polar and subpolar foraminifer species. This might hint towards a possible meltwater-related perturbation of the prevailing upper ocean

    The human adenovirus 5 E1A region can immortalize primary cultures of baby rat kidney cells, but requires the presence of the E1B region for complete oncogenic transformation. One of the effects of the E1B region in the transformation process is the activation of E1A expression. We have investigated the mechanism of this stimulation of E1A expression using nuclear run-on assays with nuclei from Ad5 E1A- and Ad5 E1-transformed cells. It was found that E1B enhances E1A at the level of transcription-initiation. This activation is mainly observed when the E1A and E1B regions are integrated simultaneously into the cellular genome and only minimally when these genes are integrated separately, strongly suggesting that a close physical linkage of these regions is essential for the observed effect.

  3. Evidence for Stable Sea-level during Marine Isotope Stage 5e of the Last Interglacial from the Western Mediterranean

    Marine isotope stage (MIS) 5e of the last interglacial (LIG) is of great interest because it serves as an analog for the Holocene. Changes in sea-level are, in part, indicative of the global-scale changes in climate. Unlike the stable Holocene, significant drops and/or rises, up to nine meters, have been reported during MIS-5e, suggesting that MIS-5e climate may not have been as stable as the Holocene. Phreatic overgrowths on speleothems (POS) from coastal caves of Mallorca Island (Spain) are deposited less than 40 cm below the brackish water/air interface (water table) at elevations equivalent to sea-level. Thus, stable sea-level stands result in POS that have grown large enough to be used as accurate sea-level markers. Like reefs, the POS are also discontinuous in their coverage of sea-level through time, but the method potentially locates both the position and the age of a particular past sea-level stand with very high accuracy and precision. Uranium-series dating of 18 POS samples from ten Mallorcan caves indicates that for 11,000 years (between 127.4 +/- 0.5 and 116.3 +/- 1.3 ka) the sea-level was remarkably stable at 2.25 +/- 0.75 m above the present sea-level. Given there were any deviations from this Mallorcan MIS-5e sea-level, they were likely too rapid to form POS. Also indicated by our record is a fast 5 mm/year decline in sea-level from MIS-5e to -5d, and from MIS-5b to -5a sea-level rose at 18 mm/year, peaked for 1000 years, then fell rapidly at 5-10 mm/year at the onset of MIS 4. In all, these changes roughly follow Northern Hemisphere summer insolation. Further uranium-series dating of highstands preceding MIS-5 are ongoing to document the tectonic stability of the Mallorcan sea-level site.

    The Edison Demonstration of Smallsat Networks (EDSN) is a technology demonstration mission that provides a proof of concept for a constellation or swarm of satellites performing coordinated activities. Networked swarms of small spacecraft will open new horizons in astronomy, Earth observations and solar physics. Their range of applications include the formation of synthetic aperture radars for Earth sensing systems, large aperture observatories for next generation telescopes and the collection of spatially distributed measurements of time varying systems, probing the Earths magnetosphere, Earth-Sun interactions and the Earths geopotential. EDSN is a swarm of eight 1.5U Cubesats with crosslink, downlink and science collection capabilities developed by the NASA Ames Research Center under the Small Spacecraft Technology Program (SSTP) within the NASA Space Technology Mission Directorate (STMD). This paper describes the concept of operations of the mission and planned scientific measurements. The development of the 8 satellites for EDSN necessitated the fabrication of prototypes, Flatsats and a total of 16 satellites to support the concurrent engineering and rapid development. This paper has a specific focus on the development, integration and testing of a large number of units including the lessons learned throughout the project development.

    One of the most important roles of science is to inform the discussions and decisions of individuals and institutions. In a world that is changing rapidly, information is urgently needed to help citizens and leaders understand what's happening, what's causing changes, what the implications are and what are the likely consequences of various options. Most everyone agrees that decisions should be informed (not dictated) by scientific information, but achieving that goal has proven a challenge. Decision-makers need to have access to scientific information that is understandable, relevant, useable, current and credible. However, the science is complex, nuanced and difficult to communicate simply. Most scientists are ill equipped to speak in language that is non-technical. Many academic scientists are wary of talking to the press. Academia does not generally reward time spent doing outreach. As a consequence, others step into the breach and communicate their version of `the science.' All too often this means that vested interests spin, distort or cherry-pick information. The result is that decisions are made without good scientific knowledge and science is seen increasingly as a weapon, not as useful knowledge. The presentation will focus on how one program, the Aldo Leopold Leadership Program is training academic environmental scientists to be better communicators of their science to non-scientists. Lessons learned and suggestions for revolutionizing the communication of scientific information will be offered.

    These lessons learned are part of a suite of hardware, software, test results, designs, knowledge base, and documentation that comprises the legacy of the Constellation Program. The context, summary information, and lessons learned are presented in a factual format, as known and described at the time. While our opinions might be discernable in the context, we have avoided all but factually sustainable statements. Statements should not be viewed as being either positive or negative; their value lies in what we did and what we learned that is worthy of passing on. The lessons include both "dos" and "don ts." In many cases, one person s "do" can be viewed as another person s "don t"; therefore, we have attempted to capture both perspectives when applicable and useful. While Volume I summarizes the views of those who managed the program, this Volume II encompasses the views at the working level, describing how the program challenges manifested in day-to-day activities. Here we see themes that were perhaps hinted at, but not completely addressed, in Volume I: unintended consequences of policies that worked well at higher levels but lacked proper implementation at the working level; long-term effects of the "generation gap" in human space flight development, the need to demonstrate early successes at the expense of thorough planning, and the consequences of problems and challenges not yet addressed because other problems and challenges were more immediate or manifest. Not all lessons learned have the benefit of being operationally vetted, since the program was cancelled shortly after Preliminary Design Review. We avoid making statements about operational consequences (with the exception of testing and test flights that did occur), but we do attempt to provide insight into how operational thinking influenced design and testing. The lessons have been formatted with a description, along with supporting information, a succinct statement of the lesson learned, and

    Among the principal objectives of the Phase 1 NASA/Mir program were for the United States to gain experience working with an international partner, to gain working experience in long-duration space flight, and to gain working experience in planning for and executing research on a long-duration space platform. The Phase 1 program was to provide to the US early experience prior to the construction and operation of the International Space Station (Phase 2 and 3). While it can be argued that Mir and ISS are different platforms and that programmatically Phase 1 and ISS are organized differently, it is also clear that many aspects of operating a long-duration research program are platform independent. This can be demonstrated by a review of lessons learned from Skylab, a US space station program of the mid-1970's, many of which were again "learned" on Mir and are being "learned" on ISS. Among these are optimum crew training strategies, on-orbit crew operations, ground support, medical operations and crew psychological support, and safety certification processes

    2003-02-24

    The Sellafield site in North West England has over 240 active facilities covering the full nuclear cycle from fuel manufacture through generation, reprocessing and waste treatment. The Sellafield decommissioning programme was formally initiated in the mid 1980s though several plants had been decommissioned prior to this primarily to create space for other plants. Since the initiation of the programme 7 plants have been completely decommissioned, significant progress has been made in a further 16 and a total of 56 major project phases have been completed. This programme update will explain the decommissioning arrangements and strategies and illustrate the progress made on a number of the plants including the Windscale Pile Chimneys, the first reprocessing plan and plutonium plants. These present a range of different challenges and requiring approaches from fully hands on to fully remote. Some of the key lessons learned will be highlighted.

    The privileged location of Santa Maria Island (Azores archipelago) in the middle of the North Atlantic makes the fossiliferous outcrops on this island of utmost importance to gain a better understanding of how coeval living communities relate to the broader evolutionary and biogeographic history of the Atlantic basin during the late Neogene and the Quaternary. Here we focus on this island's MIS 5e fossil record, offering a comprehensive review on the palaeobiodiversity, palaeoecology and palaeobiogeography of the biota living in the mid North Atlantic during this interglacial. Several studies in oceanic islands stress the huge impact of sea level changes on insular communities. Pleistocene sea-level changes occur during the short-time events known as "Terminations" (associated to glacial/interglacial shifts) as well as with the onset of glaciations (associated to interglacial/glacial shifts). Both are responsible for extinctions and local disappearance of species, bottleneck effects and formation of new species, resulting in community structure changes. This work increases the number of fossil marine taxa reported from the Last Interglacial deposits of Santa Maria to 143 species. All the 19 new records are molluscs (13 gastropods and 6 bivalves), thus increasing the number of fossil molluscs to 136 species. Although thermophilic members of the "Senegalese" tropical fauna were found in these deposits, many of the most emblematic species (e.g., Persististrombus latus (=Strombus bubonius), Cymbula safiana, Harpa doris, Cardita senegalensis, Barbatia plicata, Ctena eburnea or Hyotissa hyotis) are absent, suggesting that they did not reach the Azores. Our results indicate that the main differences between the species composition of the MIS 5e and the present-day shallow-water Azorean communities are probably due to the dropping of sea surface temperature associated with the onset of the last glaciation, which had both direct and indirect effects on species ecology.

    1998-01-01

    During the Cassini Radioisotope Thermoelectric Generator (RTG) program, the heritage RTG design was reviewed and modified to incorporate lessons learned. Design changes were made both to resolve problems as they occurred and to correct difficulties noted in earlier missions. Topics addressed in this paper included problems experienced previously at the launch facility in attaching the pressure relief device to the generators, and the open circuit conditions that occurred at times in the resistance temperature device wiring harness. Also discussed is a problem caused by mistakes in software configuration management. How lessons learned refined the RTG design and integration with the spacecraft are discussed and the adopted solutions are described.

  3. Contrasted ocean conditions in the northwest North Atlantic during marine isotope stages (MIS) 11, 5e and 1

    2014-05-01

    Cores raised during the IODP Expedition 303 in the north Atlantic were analysed to document paleoceanographical conditions during recent interglacials (cf. Hillaire-Marcel et al., Marine Geol. 2011). Two key sites illustrate conditions in the inner vs outer Labrador Sea, respectively at the southwest Greenland margin (Eirik Ridge Site 1305; 57° N-48° W) and the southern Labrador rise (Orphan Knoll Site 1302/1303; 50° N-45° W). Special attention was paid to marine isotope stages (MIS) 11 (ca. 424-324 ka), 5e (ca. 128-117 ka) and the Holocene (last 11,000 years). The microfossil content of sediments (dinocyst notably) and the isotopic composition of foraminifers indicate significant differences in the conditions that prevailed during these 3 interglacial stages. Optimal conditions with regard to sea-surface temperatures (SSTs) prevailed during MIS 5e (anomalies of about + 5° C) at both sites. However, occurrence of ice rafted debris (IRD) and variations in salinity suggest meltwater discharge along the Greenland and Labrador margins during the last interglacial. On the contrary, during MIS 11, SSTs were similar to modern off Greenland or slightly lower at Orphan Knoll, but salinity was higher at both sites and IRD close to nil, whereas both sites are presently under iceberg routes. Stable oxygen isotope values in the mesopelagic Neogloboquadrina pachyderma left coiled (Npl), are generally not unlike values observed during MIS 9 or 7, i.e., slightly higher than those which characterized MIS 5e and the present interglacial, particularly in the outer Labrador Sea. This points to either a higher salinity and or a lower temperature in the subsurface water layer occupied by Npl. Low IRD, high salinity together with relatively high 18O values in foraminifers suggest limited influence of meltwater from ice cap and sea ice during MIS 11, especially the first part of the interglacial.

    The diorganotin(IV) complexes of 5-[(E)-2-aryldiazen-1-yl]-2-hydroxybenzoic acid are of interest because of their structural diversity in the crystalline state and their interesting biological activity. The structures of dimethylbis{2-hydroxy-5-[(E)-2-(4-methylphenyl)diazen-1-yl]benzoato}tin(IV), [Sn(CH3)2(C14H11N2O3)2], and di-n-butylbis{2-hydroxy-5-[(E)-2-(4-methylphenyl)diazen-1-yl]benzoato}tin(IV) benzene hemisolvate, [Sn(C4H9)2(C14H11N2O3)2]·0.5C6H6, exhibit the usual skew-trapezoidal bipyramidal coordination geometry observed for related complexes of this class. Each structure has two independent molecules of the Sn(IV) complex in the asymmetric unit. In the dimethyltin structure, intermolecular O-H...O hydrogen bonds and a very weak Sn...O interaction link the independent molecules into dimers. The planar carboxylate ligands lend themselves to π-π stacking interactions and the diversity of supramolecular structural motifs formed by these interactions has been examined in detail for these two structures and four closely related analogues. While there are some recurring basic motifs amongst the observed stacking arrangements, such as dimers and step-like chains, variations through longitudinal slipping and inversion of the direction of the overlay add complexity. The π-π stacking motifs in the two title complexes are combinations of some of those observed in the other structures and are the most complex of the structures examined. PMID:27045182

    The University of Alabama in Huntsville (UAH) experiment which flew on the STS-8 mission had several objectives which were mostly of a speculative nature since so little was known of the processes of interest. The experiment provided original, if limited, data on: (1) oxidation of metal surfaces, (2) reaction rates of atomic oxygen with carbon and other surfaces and the dependence of these rates on temperature, and (3) the angular distribution of 5eV atoms scattered off a solid surface. Provided is a review of the results, with reference given to fuller published accounts where these are available.

  6. Sub-orbital sea-level change in early MIS 5e: New evidence from the Gulf of Corinth, Greece

    New evidence from uplifted marine isotope stage (MIS) 5e carbonate deposits in the Gulf of Corinth demonstrate two rapid, sub-orbitally forced, sea-level oscillations in the early part of MIS 5e. Microbial bioherms with inter-grown marine coralline algae are interpreted as early highstand deposits. Presence of thin vadose flowstone (speleothem) coating inter-bioherm surfaces mark a short-lived regression of > 10 m, followed by sea-level recovery and re-establishment of the highstand, marked by coralline algae coating inter-bioherm cavity surfaces. These marine algae are then coated by a younger vadose flowstone, thick enough to provide an uncontaminated U/Th date of 134.8 ± 2.0 ka. The dated flowstone is itself encrusted by marine fauna and the entire sequence overlain by highstand marine sediments and marine aragonite cements dated to 114-118 ka, part of the sustained MIS 5e highstand. The age of the younger flowstone demonstrates that the early highstand occurred before 134.8 ± 2.0 ka, and uplift arguments suggest that the bioherms are unlikely to be older than ˜ 136 ka. These data are consistent with the notion that most of termination II (TII) sea-level rise had occurred before 135 ka; indeed they suggest sea-level at this time reached about 2-4 (± 4) m below present sea-level, 6-18 (± 4) m higher than previous estimates. This early highstand was itself punctuated by a rapid sea-level oscillation of > 10 m (as yet undated), and this oscillation, supported by new TII sea-level data from the Red Sea [Siddall, M., Bard, E., Rohling, E.J., Hemleben, C., 2006, Sea-level reversal during termination II, Geology, 34, 817-820.], probably occurred in about 1000 yr. The flowstone dated at 134.8 ± 2.0 ka is interpreted to record the early part of the 'Aladdin's Cave' regressive event from Papua New Guinea, although in Greece only the first 16 m of the event is recorded. The new data presented here support a recently published Red Sea TII sea-level curve: they also

  7. A global perspective on the timing and nature of sub-orbital sea level oscillations during MIS 5e

    Although multiple, sub-orbital peaks in sea level during Marine Isotope Stage (MIS) 5e have a long history in the literature, there is still debate regarding the number, timing, and magnitude of sea-level peaks. A wide range of competing scenarios have been proposed based on observations from individual field sites including: (i) a stable sea level, (ii) a stable sea level punctuated by an ephemeral drop in sea level (2 peaks), (iii) a stable sea level followed by a rapid rise (2 peaks), or (iv) several (3-4) peaks in sea level that define an oscillating trend during the highstand. While some field sites appear to have conflicting evidence regarding the timing and nature of relative sea-level changes that cannot be reconciled through glacial isostatic processes alone, clearly there must be one global mean sea level (GMSL) reconstruction that gave rise to the evidence that is presently observed in the geologic record. We take a holistic approach to understanding the evolution of sea level during the MIS 5e highstand by integrating sedimentary, floral, faunal, and geochemical evidence from coral reef sites around the globe. Our aim is to develop a scenario for sea-level change during the MIS 5e highstand that satisfies the global observational dataset. Several conclusions emerge from this analysis: (1) there are many sites that preserve clear sedimentary evidence for two distinct sub-orbital peaks in sea level, and fewer that have possible evidence for more than two peaks; (2) there is conflicting evidence as to whether these two peaks are separated by an ephemeral sea-level fall, or whether they are defined by a stable sea level followed by a rapid rise; (3) multiple sites demonstrate significantly different geochemical signatures associated with distinct generations of reef growth as defined by their U-series geochemistry, indicating different post-depositional histories that may be related to differences in post-depositional marine submergence and exposure

    Systematic evaluation of a project, product or other successes, and failures, is an important method for improving the performance of a company, as well as that of an individual. One should evaluate and determine if lessons learned can be applied to the systems and procedures being used in the company. Even if the company does not have to adjust its strategies, procedures, portfolio or systems as a result of lessons it has learned, there may be pointers to communicate to staff. It is easy for many aspects of a system to become outdated, particularly in an organization that is growing or changing rapidly. It is therefore generally appropriate to evaluate the company's regulatory compliance, toxicology compliance, clinical auditing practices and other appropriate systems on an annual or biannual basis. Most lessons of success or failure are specific to a single situation because of the combination of people, drug, competition, priorities and many other factors involved, and cannot be extrapolated to other situations. Some general lessons and principles are presented that will facilitate drug discovery, development and marketing. PMID:15616644

  12. Lessons learned related to packaging and transportation

    The use of lessons learned as a tool for learning from past experiences is well established, especially by many organizations within the nuclear industry. Every person has, at some time, used the principles of lessons learned to adopt good work practices based on their own experiences or the experiences of others. Lessons learned can also help to avoid the recurrence of adverse practices, which is often an area that most lessons-learned programs tend to focus on. This paper will discuss how lessons learned relate to packaging and transportation issues and events experienced at Department of Energy (DOE) facilities. It will also discuss the role performed by the Office of Nuclear and Facility Safety`s Office of Operating Experience Analysis and Feedback in disseminating lessons learned and operating experience feedback to the DOE complex. The central concept of lessons learned is that any organization should be able to learn from its own experiences and events. In addition, organizations should implement methodologies to scan external environments for lessons learned, to analyze and determine the relevance of lessons learned, and to bring about the necessary changes learned from these experiences. With increased concerns toward facility safety, the importance of utilizing the lessons-learned principles and the establishment of lessons-learned programs can not be overstated.

    Systems Engineering is fundamental to good engineering, which in turn depends on the integration and application of engineering lessons learned. Thus, good Systems Engineering also depends on systems engineering lessons learned from within the aerospace industry being documented and applied. About ten percent of the engineering lessons learned documented in the NASA Lessons Learned Information System are directly related to Systems Engineering. A key issue associated with lessons learned datasets is the communication and incorporation of this information into engineering processes. As part of the NASA Technical Standards Program activities, engineering lessons learned datasets have been identified from a number of sources. These are being searched and screened for those having a relation to Technical Standards. This paper will address some of these Systems Engineering Lessons Learned and how they are being related to Technical Standards within the NASA Technical Standards Program, including linking to the Agency's Interactive Engineering Discipline Training Courses and the life cycle for a flight vehicle development program.

    Artun, Hüseyin; Coştu, Bayram

    2013-02-01

    The aim of this study was to explore a group of prospective primary teachers' conceptual understanding of diffusion and osmosis as they implemented a 5E constructivist model and related materials in a science methods course. Fifty prospective primary teachers' ideas were elicited using a pre- and post-test and delayed post-test survey consisting of ten two-tier questions of which an explanatory part was integral. Individual interviews were conducted with six prospective teachers at the end of the implementation of the unit using four questions. Test scores were analyzed quantitatively and qualitatively. Post-instructional interviews were analyzed qualitatively. Statistical analysis using one-way ANOVA of student test scores pointed to statistically significant differences between pre- and post- and delayed post-test ( p < 0.05). A qualitative analysis of the prospective teachers' explanations in the two-tier questions revealed changes in their ideas overtime. Both quantitative and qualitative analyses suggest that the teaching activities promoted students' conceptual understanding. No statistically significant differences were found between post-test and delayed post-test scores, suggesting that the teaching activities based on 5E model enabled students to retain their new conceptual understanding.

  16. PDE6δ-mediated sorting of INPP5E into the cilium is determined by cargo-carrier affinity.

    The phosphodiesterase 6 delta subunit (PDE6δ) shuttles several farnesylated cargos between membranes. The cargo sorting mechanism between cilia and other compartments is not understood. Here we show using the inositol polyphosphate 5'-phosphatase E (INPP5E) and the GTP-binding protein (Rheb) that cargo sorting depends on the affinity towards PDE6δ and the specificity of cargo release. High-affinity cargo is exclusively released by the ciliary transport regulator Arl3, while low-affinity cargo is released by Arl3 and its non-ciliary homologue Arl2. Structures of PDE6δ/cargo complexes reveal the molecular basis of the sorting signal which depends on the residues at the -1 and -3 positions relative to farnesylated cysteine. Structure-guided mutation allows the generation of a low-affinity INPP5E mutant which loses exclusive ciliary localization. We postulate that the affinity to PDE6δ and the release by Arl2/3 in addition to a retention signal are the determinants for cargo sorting and enrichment at its destination. PMID:27063844

    NASA policy requires each Program or Project to develop a plan for how they will address Lessons Learned. Projects have the flexibility to determine how best to promote and implement lessons learned. A large project might budget for a lessons learned position to coordinate elicitation, documentation and archival of the project lessons. The lessons learned process crosses all NASA Centers and includes the contactor community. o The Office of The Chief Engineer at NASA Headquarters in Washington D.C., is the overall process owner, and field locations manage the local implementation. One tool used to transfer knowledge between program and projects is the Lessons Learned Information System (LLIS). Most lessons come from NASA in partnership with support contractors. A search for lessons that might impact a new design is often performed by a contractor team member. Knowledge is not found with only one person, one project team, or one organization. Sometimes, another project team, or person, knows something that can help your project or your task. Knowledge sharing is an everyday activity at the Kennedy Space Center through storytelling, Kennedy Engineering Academy presentations and through searching the Lessons Learned Information system. o Project teams search the lessons repository to ensure the best possible results are delivered. o The ideas from the past are not always directly applicable but usually spark new ideas and innovations. Teams have a great responsibility to collect and disseminate these lessons so that they are shared with future generations of space systems designers. o Leaders should set a goal for themselves to host a set numbers of lesson learned events each year and do more to promote multiple methods of lessons learned activities. o High performing employees are expected to share their lessons, however formal knowledge sharing presentation are not the norm for many employees.

  18. EMU Lessons Learned Database

    As manned space exploration takes on the task of traveling beyond low Earth orbit, many problems arise that must be solved in order to make the journey possible. One major task is protecting humans from the harsh space environment. The current method of protecting astronauts during Extravehicular Activity (EVA) is through use of the specially designed Extravehicular Mobility Unit (EMU). As more rigorous EVA conditions need to be endured at new destinations, the suit will need to be tailored and improved in order to accommodate the astronaut. The Objective behind the EMU Lessons Learned Database(LLD) is to be able to create a tool which will assist in the development of next-generation EMUs, along with maintenance and improvement of the current EMU, by compiling data from Failure Investigation and Analysis Reports (FIARs) which have information on past suit failures. FIARs use a system of codes that give more information on the aspects of the failure, but if one is unfamiliar with the EMU they will be unable to decipher the information. A goal of the EMU LLD is to not only compile the information, but to present it in a user-friendly, organized, searchable database accessible to all familiarity levels with the EMU; both newcomers and veterans alike. The EMU LLD originally started as an Excel database, which allowed easy navigation and analysis of the data through pivot charts. Creating an entry requires access to the Problem Reporting And Corrective Action database (PRACA), which contains the original FIAR data for all hardware. FIAR data are then transferred to, defined, and formatted in the LLD. Work is being done to create a web-based version of the LLD in order to increase accessibility to all of Johnson Space Center (JSC), which includes converting entries from Excel to the HTML format. FIARs related to the EMU have been completed in the Excel version, and now focus has shifted to expanding FIAR data in the LLD to include EVA tools and support hardware such as

    Lessons Learned have been the basis for our accomplishments throughout the ages. They have been passed down from father to son, mother to daughter, teacher to pupil, and older to younger worker. Lessons Learned have also been the basis for the nation s accomplishments for more than 200 years. Both government and industry have long recognized the need to systematically document and utilize the knowledge gained from past experiences in order to avoid the repetition of failures and mishaps. Through the knowledge captured and recorded in Lessons Learned from more than 80 years of flight in the Earth s atmosphere, NASA s materials researchers are constantly working to develop stronger, lighter, and more durable materials that can withstand the challenges of space. The Agency s talented materials engineers and scientists continue to build on that rich tradition by using the knowledge and wisdom gained from past experiences to create futuristic materials and technologies that will be used in the next generation of advanced spacecraft and satellites that may one day enable mankind to land men on another planet or explore our nearest star. These same materials may also have application here on Earth to make commercial aircraft more economical to build and fly. With the explosion in technical accomplishments over the last decade, the ability to capture knowledge and have the capability to rapidly communicate this knowledge at lightning speed throughout an organization like NASA has become critical. Use of Lessons Learned is a principal component of an organizational culture committed to continuous improvement.

  4. Lessons from risk assessment of countermine robotic systems

    Chappell, Isaac; Moses, Franklin L.; Aeillo, Matthew P.

    2011-05-01

    The U.S. Army's desire for increased standoff distances between Soldiers and disguised explosive threats has yielded a complex new technical challenge: augment existing small military robots with state-of-the-art detection and neutralization technology. The magnitude of the challenge is increased by the need for reliable autonomy that allows the robot to operate in different environments (e.g., complex and urban terrains, confined areas, and underground locations). This paper describes lessons learned during efforts in 2008-09 to identify and remediate risks of developing a countermine robot system. It also addresses issues that need attention to achieve total mission success. The work studied three phases of a robotic countermine system: move to a threat area, investigate that area with sensor(s), and neutralize detected threats. Each of these phases is essential, yet attention tends to focus on the third one. The focus of this paper is on risks and lessons pertaining to the first two. What was learned about moving a countermine robot to the area of expected threats? What is necessary for a robot to maneuver sensors and have the maximum probability of detection (Pd) of hazards while minimizing the false alarm rate (FAR)? This paper presents observations during demonstration and test events over the past 2 years. From those observations, lessons learned are summarized as a foundation for realizing a countermine robot and a path forward.

    A polycrystalline Cu{sub 2}ZnSnS{sub 4} thin film was deposited on fused quartz by co-evaporation. The selected thickness was {approx}100 nm to avoid artifacts in its optical properties caused by thicker as-grown films. The composition and phase of the film were checked with x-ray fluorescence, Raman shift spectroscopy, scanning transmission electron microscopy, and energy dispersive x-ray spectroscopy. An improved spectroscopic ellipsometry methodology with two-side measurement geometries was applied to extract the complex dielectric function {var_epsilon} = {var_epsilon}{sub 1} + i{var_epsilon}{sub 2} of the Cu{sub 2}ZnSnS{sub 4} thin film between 0.73 and 6.5 eV. Five critical points were observed, at 1.32 (fundamental band gap), 2.92, 3.92, 4.96, and 5.62 eV, respectively. The {var_epsilon} spectra are in reasonable agreement with those from theoretical calculations.

    Klügel, Jens-Uwe

    2014-05-01

    The Fukushima nuclear catastrophe has led to a wide-spread international discussion on how seismic and tsunami hazards can be better predicted and adverse consequences be prevented.In some countries the event led to the complete phase-out of nuclear energy. The lessons drawn by different organisations including earth scientists, earthquake engineers,non-governmental and governmental organisations will be reviewed from an independent position. This review captures the following areas: 1) Hazard assessment 2) Engineering design and defense in depth concepts 3) Emergency preparedness It is shown that not all important lessons from the catastrophe have been drawn. Especially the need of an holistic approach towards hazard assessment and the implementation of defense in depth and diversity of design principles for critical infrastructures like nuclear power plants hast to be stronger emphasized to prevent similar disasters.

  10. Last interglacial (MIS5e) sea-levels and uplift along the north-east Gulf of Aqaba

    An uplifted flight of coral reef terraces, extending along the north-east margin of the Gulf of Aqaba (GOA), provides evidence for uplift rates and sea level high stands. GOA fills a narrow and deep tectonic depression lying along the southern sector of the Dead Sea Transform where it meets the Red Sea. This special configuration of the GOA and its latitude turn it into a dependable paleo-sea level monitor, sensitive only to global eustatic changes and local tectonic movements. A sequence of five uplifted coral reef terraces were mapped and characterized on basis of morphology and reef-facies, and their elevation above the present sea level was determined. The fossil reefs studied comprise fringing reefs, some with clear reef-structure that includes a reef flat and a shallow back lagoon. Most outcrops in the study area represent a transgressive sequence in which, during its highest stand, formed fringing reef terraces. We use U-Th ages of fossil corals samples found in growth position at various terraces. Corals from three uplifted reef terraces, R1, R2, and R3 were dated to the last interglacial period particularly to marine isotope stage (MIS) 5e. These ages were achieved from mainly calcitic corals (recrystallized in a freshwater phreatic environment). A few ages were derived from aragonite corals. The three terraces represent three sub-stages within MIS5e: R3 formed during a short standstill at ~130 ka BP; R2 formed during a long and steady standstill between ~128 to ~121 ka BP; and R1 represents a short standstill at ~117 ka BP. Assuming that terrace reef flats represent past sea level high stands, we calculated the coast average uplift rate and constrained the original terraces elevations. The reconstructed eustatic sea level variation during MIS 5e at GOA resembles observations from reef terraces in other locations. Combined, all indicate a significant sea-level rise from the MIS 6 low stand at ~134-130 ka and followed by a long and stable sea level high

    2011-01-01

    Planning products and procedures that allowed the mission Flight Control Teams and the Astronaut crews to plan, train and fly every Space Shuttle mission were developed by the Flight Planning Branch at the NASA Johnson Space Center in Houston, Texas. As the Space Shuttle Program came to a close, lessons learned were collected from each phase of the successful execution of these Space Shuttle missions. Specific examples of how roles and responsibilities of console positions that develop the crew and vehicle attitude timelines have been analyzed and will be discussed. Additionally, the relationships and procedural hurdles experienced through international collaboration have molded operations. These facets will be explored and related to current and future operations with the International Space Station and future vehicles. Along with these important aspects, the evolution of technology and continual improvement of data transfer tools between the Space Shuttle and ground team has also defined specific lessons used in improving the control team s effectiveness. Methodologies to communicate and transmit messages, images, and files from the Mission Control Center to the Orbiter evolved over several years. These lessons were vital in shaping the effectiveness of safe and successful mission planning and have been applied to current mission planning work in addition to being incorporated into future space flight planning. The critical lessons from all aspects of previous plan, train, and fly phases of Space Shuttle flight missions are not only documented in this paper, but are also discussed regarding how they pertain to changes in process and consideration for future space flight planning.

  12. Lessons Learned from JTA Tester Safety Studies

    SciTech Connect

    R. L. Bierbaum

    2001-05-01

    EP401575, Issue C, calls out a requirement to perform safety studies for testers that are used to accept Joint Test Assembly (JTA) product at Pantex (Reference 1). The underlying motivation is to ensure that personnel hazards due to inadvertent initiation of electro-explosive devices (EEDs) during JTA testing are understood and minimized. Studies have been performed on the B61-7/11 JTA, B61-3/4/10 JTA, B83 JTA, and W76 Type 2F testers at Pantex (References 2-5). Each of these studies includes an examination of the relevant Pantex tester as well as the instrumentation and War Reserve (WR) hardware. In performing these analyses, several themes have emerged that could be useful for the Phase 6.3 design efforts for the weapons, the associated instrumentation, and the JTA testers. This report summarizes the lessons learned from these studies. Note that in some cases, the recommendations provided below to enhance safety during JTA testing operations (e.g., adding isolation resistors in the monitoring lines) may result in a reliability degradation or other surety impact. Thus it is important to consider these lessons learned in the context of the overall design and to make tradeoffs in light of the integrated surety objectives. The lessons learned are listed in five different categories, summarized as: (1) Instrumentation considerations; (2) WR design considerations; (3) Tester considerations; (4) Administrative procedures during JTA assembly; and (5) Administrative procedures prior to and during JTA testing. The first three focus on minimizing the probability of inadvertent application of power to EED initiation lines due to component, connector, and assembly failures. The last two describe procedural steps that can be taken at Pantex to either minimize the risk (e.g., by ensuring that tester power supplies cannot supply excessive power to the unit under test) or to mitigate the consequences of unexpected EED initiation (e.g., by instructing test operators to avoid

    2015-05-01

    Based upon advances in gene sequencing and construction, it is now possible to identify specific genes or sequences thereof for gene delivery applications. Recombinant adenovirus serotype-5 (Ad5) viral vectors have been utilized in the settings of gene therapy, vaccination, and immunotherapy but have encountered clinical challenges because they are recognized as foreign entities to the host. This recognition leads to an immunologic clearance of the vector that contains the inserted gene of interest and prevents effective immunization(s). We have reported on a new Ad5-based viral vector technology that can be utilized as an immunization modality to induce immune responses even in the presence of Ad5 vector immunity. We have reported successful immunization and immunotherapy results to infectious diseases and cancers. This improved recombinant viral platform (Ad5 [E1-, E2b-]) can now be utilized in the development of multiple vaccines and immunotherapies.

  14. Optical emission generated by collisions of 5 eV O(3P) atoms with surface-absorbed hydrazine

    Orient, O. J.; Martus, K. E.; Chutjian, A.; Murad, E.

    1992-01-01

    Optical emission has been observed corresponding to vibrational bands in the NH (A 3Pi - X 3Sigma(-)) electronic transition during collisions of 5 eV, ground-state oxygen O(3P) atoms with MgF2 and Ni surfaces continuously exposed to a beam of hydrazine (N2H4). The NH emission intensity is observed to be about five times greater for MgF2 than for Ni. No dependence on temperature was observed for either surface in the range 240 - 340 K, implying that the NH-producing intermediate species is tightly bound. The half-lifetime for desorption of hydrazine from each surface was measured. This was found to be 120 min for the MgF2 surface at 240 K, and less than 20 min for Ni. After exposure, the surface composition was measured using X-ray photoelectron spectroscopy on the exposed and unexposed areas of both targets.

  15. Tsunami deposits at MIS Stages 5e and 9 on Oahu, Hawaii: implications for sea level at interglacial stages

    Sandy, basalt-coral conglomerates associated with both beachrock and coral reefs are found at high elevations on Oahu, Hawaii. They have been attributed to either brief, sea level high-stands or storms. The Kahe Point conglomerates are at 12.5 m elevation, whereas the main stage MIS-5e reef at this location has a maximum elevation of 8.2 m. They are loosely consolidated and poorly cemented, graded, poorly sorted, and with varying amounts of basalt and coral clasts ranging from cobble to boulder size. Coral in these deposits has been U-series dated by us at between 120-125 ka (n=5). Four distinct beds, with a gently seaward tilt, are recognized in a road cut section, with each bed composed of a few cm-thick topset bed of fine-grained, shelly, calcareous sand to silt. Similar high elevation conglomerates and 5e reefs are also described at Mokapu and Kaena Points on Oahu, indicating an island-wide deposit. Older coral clasts, dated at 130 to 142 ka (n=6; oldest by alpha spectrometry) found in association with the stage 5e corals suggest reworking and incorporation of older low-stand reef material. The coarse grain size of the conglomerates indicates deposition from a high-energy event; thus a high-stand source is ruled out. We also consider that the overall lithology and up to 0.5 m bed thickness not to be the result of storms; a series of high frequency storm events is considered unlikely. The weight of the evidence in our opinion clearly indicates deposition by a series of tsunami waves. If correct, this has implications for “probabilistic” models of sea level peaks at least 6.6 m higher than present at stage 5e that use such data in their models (e. g., Kopp et al., 2009), at least for Oahu. Within about 2 km of the Kahe deposit, in a road cut at Ko Olina, there is another markedly similar high-energy, sandy basalt-bearing coral conglomerate sequence at 21 to 25 m elevation. There are at least two distinct beds about one meter in thickness, both gently seaward

    Employing the research-based curricular planning approach called the 5E Model (Engage, Explore, Explain, Elaborate, Evaluate), five planetarium based labs for non-science majors are being developed to address two overarching content learning objectives: students will leave the instruction with the ability 1) to find and describe the location of celestial objects using compass direction, altitude, magnitude, and angles between stars and 2) to predict the apparent motions of the Sun, Moon, and stars from different positions on Earth. Using two-tiered assessment, the effectiveness of the curriculum's ability to foster conceptual change will be evaluated over the course of a semester. Student confidence and interest will also be assessed.

    SMART-1 is the first of the small missions for advanced research and technology as part of ESA's science programme “Cosmic vision”. It was successfully launched on September 27, 2003 and is presently traveling towards its destination, the Moon. The main objective of the mission, to demonstrate solar electric primary propulsion for future Cornerstones (such as Bepi-Colombo), has already been achieved. At the time of writing the electric propulsion system has been working already for more than 3400 h and has provided a Delta-V to the spacecraft of more than 2500 m/s. The other technology objectives are also being fulfilled by the verification of the proper functioning of such on-board experiments like the X-Ka band transponder, the X-ray spectrometer, the near IR spectrometer, the laser link, etc. The scientific objectives are related to lunar science and will be fulfilled once the spacecraft enters its operational lunar orbit, currently expected for January 2005. SMART-1 lunar science investigations will include studies of the chemical composition of the Moon, of geophysical processes, environment and high-resolution studies in preparation for future steps of lunar exploration. SMART-1 has been an innovative mission in many aspects and we are now drawing some preliminary conclusions about the lessons to be learnt. The paper describes the spacecraft and the technology elements with particular emphasis to the technology nature of the mission. The on-board avionics employs many novel designs for spacecraft, including a serial CAN bus for data communication, autonomous star trackers and extensive use of auto-code generation for implementing the attitude control system and the failure, detection, isolation and recovery (FDIR). Finally, the orbital operation phase currently ongoing, including the routine electric propulsion operations and the instrument commissioning, is providing a wealth of data and lesson-learnt useful for future autonomous planetary missions.

    The Boston Science Partnership has created a comprehensive set of graduate courses that immerse teachers in the science topics most relevant to their teaching practices. In these courses, teachers become students of science, developing their conceptual understandings through scientific inquiry. All courses are co-taught by a university faculty and teacher leaders from the Boston Public Schools. Each course provides contextual linkages between the science content and the standards-based curriculum of the Boston Public School district. One of the most relevant science topics to teachers and students of all disciplines is climate change. This served as the overarching theme for our course delivered during summer 2008 and 2009. This course focused on weather and the pivotal role that water and solar radiation play in the exchange of energy at the Earth's surface. Basic concepts such as the behavior of gases, energy flow, density changes, phase changes, heat capacities, and thermal convection were applied to examine short-term weather and water dynamics and longer-term impacts on global warming and climate change. The course was designed to embrace the 7E learning cycle and instructional model, as proposed by Eisenkraft in his landmark 2003 Science Teacher article. This inquiry-based instructional model builds upon prior conceptions and engages the learner in activities in which they begin to construct meaning of a concept prior to being given an explanation. Each day focused on an essential topic related to weather and climate change, and experiential learning was our main objective. There were many successes and challenges with our course. Twenty-five participants were enrolled, and all had different background knowledge and skill sets. Additionally, their level of teaching varied greatly, from K-12, so the level of depth with which to learn the content in order to bring it back to their classrooms varied a great deal as well. Therefore differentiating instruction for

    During the Cassini Radioisotope Thermoelectric Generator (RTG) program, the heritage RTG design was reviewed and modified to incorporate lessons learned. Design changes were made both to resolve problems as they occurred and to correct difficulties noted in earlier missions. Topics addressed in this paper included problems experienced previously at the launch facility in attaching the pressure relief device to the generators, and the open circuit conditions that occurred at times in the resistance temperature device wiring harness. Also discussed is a problem caused by mistakes in software configuration management. How lessons learned refined the RTG design and integration with the spacecraft are discussed and the adopted solutions are described. {copyright} {ital 1998 Lockheed Martin Missles and Space, reproduced with permission.}

    The Assistant Secretary of the Army for Research, Development and Acquisition directed the Army Safety Center to provide an audit of the causes of accidents and safety of use restrictions on recently fielded systems by tracking residual hazards back through the acquisition process. The objective was to develop ''lessons learned'' that could be applied to the acquisition process to minimize mishaps in fielded systems. System safety management lessons learned are defined as Army practices or policies, derived from past successes and failures, that are expected to be effective in eliminating or reducing specific systemic causes of residual hazards. They are broadly applicable and supportive of the Army structure and acquisition objectives. 29 refs., 7 figs.

  8. Test Planning Approach and Lessons

    Parkinson, Douglas A.; Brown, Kendall K.

    2004-01-01

    As NASA began technology risk reduction activities and planning for the next generation launch vehicle under the Space Launch Initiative (SLI), now the Next Generation Launch Technology (NGLT) Program, a review of past large liquid rocket engine development programs was performed. The intent of the review was to identify any significant lessons from the development testing programs that could be applied to current and future engine development programs. Because the primary prototype engine in design at the time of this study was the Boeing-Rocketdyne RS-84, the study was slightly biased towards LOX/RP-1 liquid propellant engines. However, the significant lessons identified are universal. It is anticipated that these lessons will serve as a reference for test planning in the Engine Systems Group at Marshall Space Flight Center (MSFC). Towards the end of F-1 and J-2 engine development testing, NASA/MSFC asked Rocketdyne to review those test programs. The result was a document titled, Study to Accelerate Development by Test of a Rocket Engine (R-8099). The "intent (of this study) is to apply this thinking and learning to more efficiently develop rocket engines to high reliability with improved cost effectivenes" Additionally, several other engine programs were reviewed - such as SSME, NSTS, STME, MC-1, and RS-83- to support or refute the R-8099. R-8099 revealed two primary lessons for test planning, which were supported by the other engine development programs. First, engine development programs can benefit from arranging the test program for engine system testing as early as feasible. The best test for determining environments is at the system level, the closest to the operational flight environment. Secondly, the component testing, which tends to be elaborate, should instead be geared towards reducing risk to enable system test. Technical risk can be reduced at the component level, but the design can only be truly verified and validated after engine system testing.

    The purpose of this report is to identify possible issues highlighted by these lessons learned that could apply to the NGNP in reducing technical risks commensurate with the current phase of design. Some of the lessons learned have been applied to the NGNP and documented in the Preconceptual Design Report. These are addressed in the background section of this document and include, for example, the decision to use TRISO fuel rather than BISO fuel used in the Peach Bottom reactor; the use of a reactor pressure vessel rather than prestressed concrete found in Fort St. Vrain; and the use of helium as a primary coolant rather than CO2. Other lessons learned, 68 in total, are documented in Sections 2 through 6 and will be applied, as appropriate, in advancing phases of design. The lessons learned are derived from both negative and positive outcomes from prior HTGR experiences. Lessons learned are grouped according to the plant, areas, systems, subsystems, and components defined in the NGNP Preconceptual Design Report, and subsequent NGNP project documents.

    Sea-level position has a direct control on coral reef morphology and composition. Examining changes in these parameters in fossil reefs can inform reconstructions of past sea-level behavior and, indirectly, ice sheet dynamics. Here we provide a detailed examination of fossil reefs from Marine Isotope Stage (MIS) 5e. These fossil reefs are located in the granitic Seychelles, which is tectonically stable site and far-field from the former margins of Northern Hemisphere ice sheets. To reconstruct relative sea level (RSL), we combine RTK and Total Station elevation surveys with sedimentary and taxonomic evaluations of eight fossil reef sites. Carbonate coralgal reef buildups of the shallowest portion of the reef are preserved in limestone outcrops that are protected by granite boulder overhangs. Two primary outcrop morphologies were observed at these sites: plastering and massive. Plastering outcrops manifest as thin (~ 1 m height x 1 m width x 0.5 m depth) vertical successions of reef framework and detritus, while massive outcrops are larger (~ 2-6 m height x 2-6 m width x 1-2 m depth). The base of these limestone outcrops consistently record a period of reef growth, characterized by corals or coralline algae colonizing the surface or face of a granite boulder and building upwards. This lower reefal unit is capped by a disconformity that is commonly overlain by coral rubble or a ~10 cm thick layer of micrite. Rubble units contain coarse fragments of the coralgal reef buildups while micrite layers consist of a relatively homogeneous fine-grained carbonate, bearing coral-dwelling, Pyrgomatid barnacles. In many of the outcrops, this succession is repeated upsection with another unit of coralgal reef framework capped by a disconformity that is recognized by the sharp transition to coral rubble or micrite with barnacles. We identified four distinct fossil coralgal assemblages in the limestone outcrops. These assemblages are consistent with modern assemblages which

  13. The divergence characteristics of constrained-sheath optics systems for use with 5-eV atomic oxygen sources

    NASA Technical Reports Server (NTRS)

    Anderson, John R.; Wilbur, Paul J.

    1989-01-01

    The potential usefulness of the constrained sheath optics concept as a means of controlling the divergence of low energy, high current density ion beams is examined numerically and experimentally. Numerical results demonstrate that some control of the divergence of typical ion beamlets can be achieved at perveance levels of interest by contouring the surface of the constrained sheath properly. Experimental results demonstrate that a sheath can be constrained by a wire mesh attached to the screen plate of the ion optics system. The numerically predicted beamlet divergence characteristics are shown to depart from those measured experimentally, and additional numerical analysis is used to demonstrate that this departure is probably due to distortions of the sheath caused by the fact that it attempts to conform to the individual wires that make up the sheath constraining mesh. The concept is considered potentially useful in controlling the divergence of ion beamlets in applications where low divergence, low energy, high current density beamlets are being sought, but more work is required to demonstrate this for net beam ion energies as low as 5 eV.

  14. Angular distributions of 5eV atomic oxygen scattered from solid surfaces on the LDEF satellite

    NASA Technical Reports Server (NTRS)

    Gregory, John C.; Peters, Palmer N.

    1992-01-01

    The angular distribution of 5eV atomic oxygen scattered off several smooth solid surfaces was measured by experiment A0114 which flew on board the Long Duration Exposure Facility (LDEF). Target surfaces were silver, vitreous carbon, and lithium fluoride crystal. The apparatus was entirely passive. It used the property of silver surfaces to absorb oxygen atoms with high efficiency; the silver is converted to optically transmissive silver oxide. A collimated beam of oxygen atoms is allowed to fall on the target surface at some pre-set angle. Reflected atoms are then intercepted by a silver film placed so that it subtends a considerable solid angle from the primary beam impact on the target surface. The silver films are evaporated onto flexible optically-clear polycarbonate sheets which are scanned later to determine oxygen uptake. While the silver detector cannot measure atom velocity or energy, its physical configuration allows easy coverage of large angular space both in the beam-plane (that which includes the incident beam and the surface normal), and in the azimuthal plane of the target surface.

    Small interfering RNA (siRNA)-mediated silencing requires siRNA loading into the RNA-induced silencing complex (RISC). Presence of 5'-phosphate (5'-P) is reported to be critical for efficient RISC loading of the antisense strand (AS) by anchoring it to the mid-domain of the Argonaute2 (Ago2) protein. Phosphorylation of exogenous duplex siRNAs is thought to be accomplished by cytosolic Clp1 kinase. However, although extensive chemical modifications are essential for siRNA-GalNAc conjugate activity, they can significantly impair Clp1 kinase activity. Here, we further elucidated the effect of 5'-P on the activity of siRNA-GalNAc conjugates. Our results demonstrate that a subset of sequences benefit from the presence of exogenous 5'-P. For those that do, incorporation of 5'-(E)-vinylphosphonate (5'-VP), a metabolically stable phosphate mimic, results in up to 20-fold improved in vitro potency and up to a threefold benefit in in vivo activity by promoting Ago2 loading and enhancing metabolic stability.

    F1F0-ATP synthase is a key enzyme of the mitochondrial energetic metabolism responsible for the production of most cellular ATP in humans. Mayr et al. (2010) recently described a patient with a homozygote (Y12C) mutation in the nuclear gene ATP5E encoding the ε-subunit of ATP synthase. To better define how it affects ATP synthase, we have modeled this mutation in the yeast Saccharomyces cerevisiae. A yeast equivalent of this mutation (Y11C) had no significant effect on the growth of yeast on non-fermentable carbon sources (glycerol/ethanol or lactate), conditions under which the activity of the mitochondrial energy transducing system is absolutely essential. In addition, similar to what was observed in patient, this mutation in yeast has a minimal effect on the ATPase/synthase activities. On the contrary, this mutation which has been shown to have a strong impact on the assembly of the ATP synthase complex in humans, shows no significant impact on the assembly/stability of this complex in yeast, suggesting that biogenesis of this complex differs significantly.

  14. Engineering Lessons Learned and Systems Engineering Applications

    NASA Technical Reports Server (NTRS)

    Gill, Paul S.; Garcia, Danny; Vaughan, William W.

    2005-01-01

    Systems Engineering is fundamental to good engineering, which in turn depends on the integration and application of engineering lessons learned and technical standards. Thus, good Systems Engineering also depends on systems engineering lessons learned from within the aerospace industry being documented and applied. About ten percent of the engineering lessons learned documented in the NASA Lessons Learned Information System are directly related to Systems Engineering. A key issue associated with lessons learned datasets is the communication and incorporation of this information into engineering processes. Systems Engineering has been defined (EINIS-632) as "an interdisciplinary approach encompassing the entire technical effort to evolve and verify an integrated and life-cycle balanced set of system people, product, and process solutions that satisfy customer needs". Designing reliable space-based systems has always been a goal for NASA, and many painful lessons have been learned along the way. One of the continuing functions of a system engineer is to compile development and operations "lessons learned" documents and ensure their integration into future systems development activities. They can produce insights and information for risk identification identification and characterization. on a new project. Lessons learned files from previous projects are especially valuable in risk

  5. Juxta-articular joint-capsule mineralization in CD73 deficient mice: Similarities to patients with NT5E mutations

    Li, Qiaoli; Price, Thea P; Sundberg, John P; Uitto, Jouni

    2014-01-01

    Arterial calcification due to CD73 deficiency (ACDC), an autosomal recessive disorder, manifests with extensive mineralization of the lower-extremity arteries as well as of hand and foot joint-capsules. This disease is caused by mutations in the NT5E gene which encodes CD73, a membrane-bound ecto-5′-nucleotidase hydrolyzing 5′-AMP into adenosine and Pi. To gain insight into the pathophysiologic details of ACDC, we have characterized a Nt5e−/− knock out mouse (Nt5etm1Jgsc) deficient in CD73. These mice, when maintained on appropriate strain background, demonstrated stiffening of the joints and micro CT revealed distinct changes in the thoracic skeletal structure with evidence of mineralization at the costochondral junctions. Mineralization was also noted in the juxta-articular spaces of the lower extremities as well as of ligaments and capsules adjacent to the bony structures. No evidence of vascular mineralization was noted either by CT or by microdissection of arteries in the thoracic area or in lower extremities. The Nt5e−/− mutant mice demonstrated significantly increased Pi levels in the serum and significantly reduced PPi concentration in the heparinized plasma, resulting in markedly increased Pi/PPi ratio, thus creating a pro-mineralization environment. In conclusion, the Nt5e−/− targeted mutant mice recapitulate some, but not all, features of ACDC and serve as a model system to study pharmacologic interventions for ectopic mineralization. Collectively, this mouse model deficient in CD73, with other targeted mutant mice with vascular mineralization, attests to the presence of a complex pro-mineralization/anti-mineralization network that under physiologic homeostatic conditions prevents ectopic tissue mineralization.

    Southwest Airlines continues to garner accolades in the areas of customer service, workforce management, and profitability. Since both the health care and airlines industries deal with a service rather than a product, the customer experience depends on the people who deliver that experience. Employees' commitment or "loyalty" to their customers, their employer, and their work translates into millions of dollars of revenue. What employee wants to work for "the worst employer in town?" Nine loyalty lessons from Southwest can be carried over to the health care setting for the benefit of employees and patients. PMID:19330974

    2011-01-01

    Once a "Troubled Project" threatened with cancellation, the Stratospheric Observatory for Infrared Astronomy (SOFIA) Program has overcome many difficult challenges and recently achieved its first light images. To achieve success, SOFIA had to overcome significant deficiencies in fundamental Systems Engineering identified during a major Program restructuring. This presentation will summarize the lessons learn in Systems Engineering on the SOFIA Program. After the Program was reformulated, an initial assessment of Systems Engineering established the scope of the problem and helped to set a list of priorities that needed to be work. A revised Systems Engineering Management Plan (SEMP) was written to address the new Program structure and requirements established in the approved NPR7123.1A. An important result of the "Technical Planning" effort was the decision by the Program and Technical Leadership team to re-phasing the lifecycle into increments. The reformed SOFIA Program Office had to quickly develop and establish several new System Engineering core processes including; Requirements Management, Risk Management, Configuration Management and Data Management. Implementing these processes had to consider the physical and cultural diversity of the SOFIA Program team which includes two Projects spanning two NASA Centers, a major German partnership, and sub-contractors located across the United States and Europe. The SOFIA Program experience represents a creative approach to doing "System Engineering in the middle" while a Program is well established. Many challenges were identified and overcome. The SOFIA example demonstrates it is never too late to benefit from fixing deficiencies in the System Engineering processes.

  14. The role of failure/problems in engineering: A commentary of failures experienced - lessons learned

    NASA Technical Reports Server (NTRS)

    Ryan, R. S.

    1992-01-01

    The written version of a series of seminars given to several aerospace companies and three NASA centers are presented. The results are lessons learned through a study of the problems experienced in 35 years of engineering. The basic conclusion is that the primary cause of problems has not been mission technologies, as important as technology is, but the neglect of basic principles. Undergirding this is the lack of a systems focus from determining requirements through design, verification, and operations phases. Many of the concepts discussed are fundamental to total quality management (TQM) and can be used to augment this product enhanced philosophy. Fourteen principles are addressed with problems experienced and are used as examples. Included is a discussion of the implication of constraints, poorly defined requirements, and schedules. Design guidelines, lessons learned, and future tasks are listed. Two additional sections are included that deal with personal lessons learned and thoughts on future thrusts (TQM).

    After 30 years of being the centerpiece of NASA s human spacecraft, the Space Shuttle will retire. This highly successful program provided many valuable lessons for the International Space Station (ISS) and future spacecraft. Major microbiological risks to crewmembers include food, water, air, surfaces, payloads, animals, other crewmembers, and ground support personnel. Adverse effects of microorganisms are varied and can jeopardize crew health and safety, spacecraft systems, and mission objectives. Engineering practices and operational procedures can minimize the negative effects of microorganisms. To minimize problems associated with microorganisms, appropriate steps must begin in the design phase of new spacecraft or space habitats. Spacecraft design must include requirements to control accumulation of water including humidity, leaks, and condensate on surfaces. Materials used in habitable volumes must not contribute to microbial growth. Use of appropriate materials and the implementation of robust housekeeping that utilizes periodic cleaning and disinfection will prevent high levels of microbial growth on surfaces. Air filtration can ensure low levels of bioaerosols and particulates in the breathing air. The use of physical and chemical steps to disinfect drinking water coupled with filtration can provide safe drinking water. Thorough preflight examination of flight crews, consumables, and the environment can greatly reduce pathogens in spacecraft. The advances in knowledge of living and working onboard the Space Shuttle formed the foundation for environmental microbiology requirements and operations for the International Space Station (ISS) and future spacecraft. Research conducted during the Space Shuttle Program resulted in an improved understanding of the effects of spaceflight on human physiology, microbial properties, and specifically the host-microbe interactions. Host-microbe interactions are substantially affected by spaceflight. Astronaut immune

  18. Climate and vegetation since the Last Interglacial (MIS 5e) in a putative glacial refugium, northern Idaho, USA

    NASA Astrophysics Data System (ADS)

    Herring, Erin M.; Gavin, Daniel G.

    2015-06-01

    There are very few terrestrial sediment records from North America that contain a nearly continuous sequence spanning from the Last Interglacial period to the present. We present stratigraphic records of pollen and several other proxies from a Carex-dominated wetland, Star Meadows, located 140 km south of the maximum extent of the Cordilleran Ice Sheet and near the current southern extent of interior mesic forests in northern Idaho. Many species in this region are disjunct by 160 km of arid steppe and dry forest from their more extensive distribution along the Pacific Northwest coast and may have survived in an interior refugium. The chronology for the upper 251 cm was determined by six radiocarbon dates and one tephra deposit, and the age of the remainder of the core (251-809 cm) was estimated by correlation with SPECMAP δ18O. Fluctuating water levels were inferred from alternating peat, biogenic silica, and aquatic pollen types. During MIS 5e the region was warmer and drier than today and was dominated by Pinus (likely Pinus contorta) mixed conifer forest surrounding a Carex meadow. A cool-moist climate (MIS 5b-5d) soon developed, and the site was inundated with deep water. Pollen indicated wetland vegetation (Betula glandulosa, Typhaceae, and Salix) developed around a lake with a Pseudotsuga/Larix and Picea forest on the surrounding slopes. During MIS 5a, a warmer climate supported a Pseudotsuga/Larix, Abies, and Picea forest on the surrounding hillsides and a Carex-dominated environment within a dry meadow. From MIS 4 to MIS 3, a cool and wet Pinus and Picea forest predominated. Water levels rose, enabling Nuphar to persist within a perennial lake while a sedge fen established along the lake margin. As climate transitioned into MIS 2, a cooler and drier climate supported a Pinus and Picea subalpine parkland, though water levels remained high enough to support Nuphar. During the Last Glacial Maximum the sediment was mainly silt and clay with high Artemisia and

  19. Alternative Energy Lessons in Scotland

    NASA Astrophysics Data System (ADS)

    Boyle, Julie

    2010-05-01

    In Scotland the new science curriculum for pupils aged 12 to 15 shall include the following outcomes: "Using my knowledge and understanding, I can express an informed view on a national or global environmental issue;" "I have participated in constructing a model to harness a renewable source of energy and can investigate how to optimise the output;" and "I can discuss why it is important to me and to the future of the world that alternatives to fossil fuels are developed." There will be an emphasis on creating lessons that will nurture responsible citizens, improve pupil engagement and allow students to develop their team working skills. To help teachers plan lessons to address this, the Scottish Schools Equipment Research Centre and Edinburgh University made teaching materials on four renewable energy resources. This poster describes how their suggested activities on solar cells, wind turbines, hydroelectric power stations and wave power were used in science lessons with twelve year old students. After an initial class discussion based on issues related to climate change and diminishing fossil fuel supplies, a workshop activity was carried out in three stages. The students were issued with a fact sheet about one of four imaginary islands (Skisdale, Cloudy Island, Surfsville and Sun City) and they were asked to work in teams to choose the most suitable method of generating electricity for their island. Issues such as costs, where it will be sited and environmental implications were considered. They were then asked to conduct practical activities by constructing and testing models for these forms of renewable energy. To conclude, they presented their proposal to the rest of the class with reasoned explanations. The kits used in the lessons can be purchased from Anderson Scientific (sales@andersonscientific.co.uk). The solar cells were simply connected to a voltmeter. The wind and hydroelectric groups used the same basic equipment. This was made using a small water

  20. Risk management and lessons learned solutions for satellite product assurance

    The historic trend of the space industry towards lower cost programmes and more generally a better economic efficiency raises a difficult question to the quality assurance community: how to achieve the same—or better—mission success rate while drastically reducing the cost of programmes, hence the cost and level of quality assurance activities. EADS Astrium Earth Observation and Science (France) Business Unit have experimented Risk Management and Lessons Learned on their satellite programmes to achieve this goal. Risk analysis and management are deployed from the programme proposal phase through the development and operations phases. Results of the analysis and the corresponding risk mitigation actions are used to tailor the product assurance programme and activities. Lessons learned have been deployed as a systematic process to collect positive and negative experience from past and on-going programmes and feed them into new programmes. Monitoring and justification of their implementation in programmes is done under supervision from the BU quality assurance function. Control of the system is ensured by the company internal review system. Deployment of these methods has shown that the quality assurance function becomes more integrated in the programme team and development process and that its tasks gain focus and efficiency while minimising the risks associated with new space programmes.

  1. Lessons learned for improving spacecraft ground operations

    NASA has a unique history in processing the Space Shuttle fleet for launches. Some of this experience has been captured in the NASA Lessons Learned Information System (LLIS). This tool provides a convenient way for design engineers to review lessons from the past to prevent problems from reoccurring and incorporate positive lessons in new designs. At the Kennedy Space Center, the LLIS is being used to design ground support equipment for the next generation of launch and crewed vehicles. This paper describes the LLIS process and offers some examples.

    Long-term sensitivity of human cells to reduced gravity has been supposed since the first Apollo missions and was demonstrated during several space missions in the past. However, little information is available on primary and rapid gravi-responsive elements in mammalian cells. In search of rapid-responsive molecular alterations in mammalian cells, short-term microgravity provided by parabolic flight maneuvers is an ideal way to elucidate such initial and primary effects. Modern biomedical research at the cellular and molecular level requires frequent repetition of experiments that are usually performed in sequences of experiments and analyses. Therefore, a research platform on Earth providing frequent, easy and repeated access to real microgravity for cell culture experiments is strongly desired. For this reason, we developed a research platform onboard the military fighter jet aircraft Northrop F-5E "Tiger II". The experimental system consists of a programmable and automatically operated system composed of six individual experiment modules, placed in the front compartment, which work completely independent of the aircraft systems. Signal transduction pathways in cultured human cells can be investigated after the addition of an activator solution at the onset of microgravity and a fixative or lysis buffer after termination of microgravity. Before the beginning of a regular military training flight, a parabolic maneuver was executed. After a 1 g control phase, the parabolic maneuver starts at 13,000 ft and at Mach 0.99 airspeed, where a 22 s climb with an acceleration of 2.5 g is initiated, following a free-fall ballistic Keplerian trajectory lasting 45 s with an apogee of 27,000 ft at Mach 0.4 airspeed. Temperature, pressure and acceleration are monitored constantly during the entire flight. Cells and activator solutions are kept at 37 °C during the entire experiment until the fixative has been added. The parabolic flight profile provides up to 45 s of

    2003-01-01

    Drawing lessons from international experience for health care reform in the United States requires striking a difficult balance between historical determinism and free will, between cynical pessimism and naïve optimism. The key to this puzzle may lie in a paradox: the United States is the most successful exporter of public health policy ideas and instruments yet has failed to build an effective health care system. General ideas (like notions about the role of competition) and microinstruments (like diagnosis-related groups) travel better than do health care systems. Ideas can be adapted to local circumstances, and instruments may easily fit into preexisting systems. Importing systems from countries with different histories and institutions would require a tectonic shift in the American political landscape. PMID:12511387

    An Agency team collaboration pilot was conducted from July 2002 until June 2003 and then extended for an additional year. The objective of the pilot was to assess the value of collaboration tools and adoption processes as applied to NASA teams. In an effort to share knowledge and experiences, the lessons that have been learned thus far are documented in this report. Overall, the pilot has been successful. An entire system has been piloted - tools, adoption, and support. The pilot consisted of two collaboration tools, a team space and a virtual team meeting capability. Of the two tools that were evaluated, the team meeting tool has been more widely accepted. Though the team space tool has been met with a lesser degree of acceptance, the need for such a tool in the NASA environment has been evidenced. Both adoption techniques and support were carefully developed and implemented in a way that has been well received by the pilot participant community.

    In July 1994, tropical storm Alberto brought heavy rains to parts of Alabama, Florida, and Georgia. In South Georgia, rivers rose 44 feet above flood stage, muddy water covered 10,000 square miles, and 31 lives were lost. In implementing the Health and Medical Services portion of the FEMA Federal Response Plan, the Public Health Service learned lessons from this experience that can be applied to planning for other natural disasters. Continuous reassessment to assure the best utilization of resources in rapidly changing conditions, cross-training in the content of emergency plans at all levels, and on-going face-to-face liaison among response managers will improve response efforts. Populations with special medical needs must become part of any response design. The effects that any response activity may have on the community as a whole should be carefully considered before action is taken. Images p685-a p687-a PMID:8570818

  7. Drug discovery: lessons from evolution

    PubMed Central

    Warren, John

    2011-01-01

    A common view within the pharmaceutical industry is that there is a problem with drug discovery and we should do something about it. There is much sympathy for this from academics, regulators and politicians. In this article I propose that lessons learnt from evolution help identify those factors that favour successful drug discovery. This personal view is influenced by a decade spent reviewing drug development programmes submitted for European regulatory approval. During the prolonged gestation of a new medicine few candidate molecules survive. This process of elimination of many variants and the survival of so few has much in common with evolution, an analogy that encourages discussion of the forces that favour, and those that hinder, successful drug discovery. Imagining a world without vaccines, anaesthetics, contraception and anti-infectives reveals how medicines revolutionized humanity. How to manipulate conditions that favour such discoveries is worth consideration. PMID:21395642

    Not since the Korean War have the Canadian Forces engaged in combat missions like those in Afghanistan. Combat, asymmetric warfare, violent insurgency and the constant threat of improvised explosive devices all contribute to the psychological stressors experienced by Canadian soldiers. Mental health teams deployed with the soldiers and provided assessment, treatment and education. Lessons learned included refuting the myth that all psychological disorders would be related to trauma; confirming that most patients do well after exposure to trauma; confirming that treating disorders in a war zone requires flexible and creative adaptation of civilian treatment guidelines; and confirming that in a combat mission mental health practice is not limited to the clinical setting.

    1993-07-01

    A series of workshops have provided extensive feedback on a recently published manual, Monitoring Guidelines to Evaluate Effects of Forestry Activities on Streams in the Pacific Northwest and Alaska (Guidelines) (MacDonald et al., 1991). These workshops and other discussions have led to the identification of fourteen additional 'lessons' for monitoring. These lessons are concepts which either were not incorporated into the Guidelines, were not sufficiently emphasized, or which are needed to put the Guidelines in context. The topics include: monitoring as a continuum; defining objectives and hypotheses; peer review; uncertainty and risk; upslope vs. instream monitoring; photo sequences; scale considerations; data storage, data interpretation, and data base management; 'activities monitoring'; and personal commitment as a critical component in monitoring projects. Many of these lessons might appear self-evident, but our experience indicates that they are often ignored. Like the Guidelines, these lessons are widely applicable and should be explicitly recognized when formulating and conducting monitoring projects. PMID:24220836

    The Vision for Space Exploration sets out a number of goals, involving both strategic and tactical objectives. These include returning the Space Shuttle to flight, completing the International Space Station, and conducting human expeditions to the Moon by 2020. Each of these goals has profound logistics implications. In the consideration of these objectives,a need for a study on NASA logistics lessons learned was recognized. The study endeavors to identify both needs for space exploration and challenges in the development of past logistics architectures, as well as in the design of space systems. This study may also be appropriately applied as guidance in the development of an integrated logistics architecture for future human missions to the Moon and Mars. This report first summarizes current logistics practices for the Space Shuttle Program (SSP) and the International Space Station (ISS) and examines the practices of manifesting, stowage, inventory tracking, waste disposal, and return logistics. The key findings of this examination are that while the current practices do have many positive aspects, there are also several shortcomings. These shortcomings include a high-level of excess complexity, redundancy of information/lack of a common database, and a large human-in-the-loop component. Later sections of this report describe the methodology and results of our work to systematically gather logistics lessons learned from past and current human spaceflight programs as well as validating these lessons through a survey of the opinions of current space logisticians. To consider the perspectives on logistics lessons, we searched several sources within NASA, including organizations with direct and indirect connections with the system flow in mission planning. We utilized crew debriefs, the John Commonsense lessons repository for the JSC Mission Operations Directorate, and the Skylab Lessons Learned. Additionally, we searched the public version of the Lessons Learned

    1988-01-01

    Infall from the circumstellar envelope onto the bright B0.5 IVe star, HD 58978 was studied. The IUE data indicate that the star was surrounded by a low and moderately ionized circumstellar shell at least 12 times between 1979 and 1988. During 6 of these episodes, the signatures of cool circumstellar material were redshifted with respect to the photosphere by 20 to 80 km/sec. The data indicate that the transition from infall to minimal shell absorption can occur in under 10 days, and are consistent either with infall phases lasting up to 6 months, or with infall episodes shorter than 10 to 15 days. The long term behavior of the shell episodes is compared with variability in the stellar wind.

  8. Paired microfossil evidence for a delayed development of fully marine surface water conditions in the Nordic seas during the Last interglacial (MIS 5e)

    2010-12-01

    Dinoflagellate cyst (dinocyst) and foraminiferal records of sediment cores from The Vøring and Iceland Plateau and south of the Fram Strait were used to reconstruct the evolution of the surface circulation in the Nordic seas during the last interglacial (Marine Isotopic Stage or MIS 5e). The location of the cores, under the modern pathway of the warm Norwegian Atlantic Current (NwAC) and within the mixing zone of the NwAC and the cold East Greenland Current (EGC), allows to reconstruct the spreading of inflowing North Atlantic surface waters across the Nordic seas during the climate progression of MIS 5e. The microfossil records, supported by stable isotope and IRD data, reveal that during the first ~6000 years of MIS 5e a more pronounced stratification and seasonality existed in the eastern Nordic seas, presumably as a result of long-lasting deglacial effects. Thus, the northward heat flux was reduced during this time in this area. It was only during late MIS 5e, and when IRD-input into the eastern Nordic seas had come to a halt, that the northward flow of warm Atlantic water masses intensified so that interglacial conditions became also eminent in the surface waters south of the Fram Strait. Our data further suggest that the stronger NwAC of late MIS 5e entailed an intensification of the EGC. While this brought comparatively colder conditions towards the Iceland Plateau it was also the only time when proper, that is fully marine, warm interglacial surface conditions co-existed in the eastern Nordic seas.

    Anti-vector immunity mitigates immune responses induced by recombinant adenovirus vector vaccines, limiting their prime-boost capabilities. We have developed a novel gene delivery and expression platform (Ad5 [E1-, E2b-]) that induces immune responses despite pre-existing and/or developed concomitant Ad5 immunity. In the present study, we evaluated if this new Ad5 platform could overcome the adverse condition of pre-existing Ad5 immunity to induce effective immune responses in prime-boost immunization regimens against two different infectious diseases in the same animal. Ad5 immune rhesus macaques (RM) were immunized multiple times with the Ad5 [E1-, E2b-] platform expressing antigens from simian immunodeficiency virus (SIV). Immunized RM developed cell-mediated immunity against SIV antigens Gag, Pol, Nef and Env as well as antibody against Env. Vaccinated and vector control RMs were challenged intra-rectally with homologous SIVmac239. During a 7-week follow-up, there was perturbation of SIV load in some immunized RM. At 7 weeks post-challenge, eight immunized animals (53%) did not have detectable SIV, compared to two RM controls (13%) (P<0.02; log-rank Mantel-Cox test). There was no correlation of protective MHC contributing to infection control. The RM without detectable circulating SIV, now hyper immune to Ad5, were then vaccinated with the same Ad5 [E1-, E2b-] platform expressing H1N1 influenza hemagglutinin (HA). Thirty days post Ad5 [E1-, E2b-]-HA vaccination, significant levels of influenza neutralizing antibody were induced in all animals that increased after an Ad5 [E1-, E2b-]-HA homologous boost. These data demonstrate the versatility of this new vector platform to immunize against two separate disease targets in the same animal despite the presence of immunity against the delivery platform, permitting homologous repeat immunizations with an Ad5 gene delivery platform.

    1999-09-01

    The Puerto Rico Electric Power Authority (PREPA) installed a distributed battery energy storage system in 1994 at a substation near San Juan, Puerto Rico. It was patterned after two other large energy storage systems operated by electric utilities in California and Germany. The U.S. Department of Energy (DOE) Energy Storage Systems Program at Sandia National Laboratories has followed the progress of all stages of the project since its inception. It directly supported the critical battery room cooling system design by conducting laboratory thermal testing of a scale model of the battery under simulated operating conditions. The Puerto Rico facility is at present the largest operating battery storage system in the world and is successfully providing frequency control, voltage regulation, and spinning reserve to the Caribbean island. The system further proved its usefulness to the PREPA network in the fall of 1998 in the aftermath of Hurricane Georges. The owner-operator, PREPA, and the architect/engineer, vendors, and contractors learned many valuable lessons during all phases of project development and operation. In documenting these lessons, this report will help PREPA and other utilities in planning to build large energy storage systems.

  19. The Network Operations Control Center upgrade task: Lessons learned

    NASA Technical Reports Server (NTRS)

    Sherif, J. S.; Tran, T.-L.; Lee, S.

    1994-01-01

    This article synthesizes and describes the lessons learned from the Network Operations Control Center (NOCC) upgrade project, from the requirements phase through development and test and transfer. At the outset, the NOCC upgrade was being performed simultaneously with two other interfacing and dependent upgrades at the Signal Processing Center (SPC) and Ground Communications Facility (GCF), thereby adding a significant measure of complexity to the management and overall coordination of the development and transfer-to-operations (DTO) effort. Like other success stories, this project carried with it the traditional elements of top management support and exceptional dedication of cognizant personnel. Additionally, there were several NOCC-specific reasons for success, such as end-to-end system engineering, adoption of open-system architecture, thorough requirements management, and use of appropriate off-the-shelf technologies. On the other hand, there were several difficulties, such as ill-defined external interfaces, transition issues caused by new communications protocols, ambivalent use of two sets of policies and standards, and mistailoring of the new JPL management standard (due to the lack of practical guidelines). This article highlights the key lessons learned, as a means of constructive suggestions for the benefit of future projects.

  20. Lessons learned from decommissioning projects at Los Alamos National Laboratory

    Salazar, M.

    1995-09-01

    This paper describes lessons learned over the last 20 years from 12 decommissioning projects at Los Alamos National Laboratory. These lessons relate both to overall program management and to management of specific projects during the planning and operations phases. The issues include waste management; the National Environmental Policy Act (NEPA); the Resource Conservation and Recovery Act (RCRA); the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA); contracting; public involvement; client/customer interface; and funding. Key elements of our approach are to be proactive; follow the observation method; perform field activities concurrently; develop strategies to keep reportable incidents from delaying work; seek and use programs, methods, etc., in existence to shorten learning curves; network to help develop solutions; and avoid overstudying and overcharacterizing. This approach results in preliminary plans that require very little revision before implementation, reasonable costs and schedules, early acquisition of permits and NEPA documents, preliminary characterization reports, and contracting documents. Our track record is good -- the last four projects (uranium and plutonium-processing facility and three research reactors) have been on budget and on schedule.

  3. Phases and Phase Transitions

    NASA Astrophysics Data System (ADS)

    Gitterman, Moshe

    2014-09-01

    In discussing phase transitions, the first thing that we have to do is to define a phase. This is a concept from thermodynamics and statistical mechanics, where a phase is defined as a homogeneous system. As a simple example, let us consider instant coffee. This consists of coffee powder dissolved in water, and after stirring it we have a homogeneous mixture, i.e., a single phase. If we add to a cup of coffee a spoonful of sugar and stir it well, we still have a single phase -- sweet coffee. However, if we add ten spoonfuls of sugar, then the contents of the cup will no longer be homogeneous, but rather a mixture of two homogeneous systems or phases, sweet liquid coffee on top and coffee-flavored wet sugar at the bottom...

  4. Lessons from the motorized migrations

    Ten experiments have been conducted to determine if cranes can be led on migration and if those so trained will repeat migrations on their own. Results have been mixed as we have experienced the mishaps common to pilot studies. Nevertheless, we have learned many valuable lessons. Chief among these are that cranes can be led long distances behind motorized craft (air and ground), and those led over most or the entire route will return north come spring and south in fall to and from the general area of training. However, they will follow their own route. Groups transported south and flown at intervals along the route will migrate but often miss target termini. If certain protocol restrictions are followed, it is possible to make the trained cranes wild, however, the most practical way of so doing is to introduce them into a flock of wild cranes. We project that it is possible to create or restore wild migratory flocks of cranes by first leading small groups from chosen northern to southern termini.

    On the basis of experience with ecological risk assessments and regulatory involvement in the process, a number of lessons can be learned relating to design, implementation, and reporting of ecological risk assessments. A number of case studies will be presented in order to evaluate the advantages and disadvantages of different approaches. Issues surrounding the selection of assessment and measurement endpoints, receptors, accuracy of models when compared with field data, bioavailability of chemicals, selection of appropriate reference sites, availability of relevant toxicological data, utility of bioassays, and accounting for temporal and seasonal variability, species adaptation, and ecological relevance will be examined. In addition, effective ways of dealing with limitations such as duration and cost of the assessments will be evaluated. Case studies ranging from large, complex Superfund sites to small, relatively simplistic sites will be included. By scrutinizing the approaches used and the outcomes of these case studies, insight can be gained that will allow risk assessors to deal with limitations and to focus future efforts to provide useful and relevant information and sound scientifically-based results.

  6. Science and Sandy: Lessons Learned

    Werner, K.

    2013-12-01

    Following Hurricane Sandy's impact on the mid-Atlantic region, President Obama established a Task Force to '...ensure that the Federal Government continues to provide appropriate resources to support affected State, local, and tribal communities to improve the region's resilience, health, and prosperity by building for the future.' The author was detailed from NOAA to the Task Force between January and June 2013. As the Task Force and others began to take stock of the region's needs and develop plans to address them, many diverse approaches emerged from different areas of expertise including: infrastructure, management and construction, housing, public health, and others. Decision making in this environment was complex with many interests and variables to consider and balance. Although often relevant, science and technical expertise was not always at the forefront of this process. This talk describes the author's experience with the Sandy Task Force focusing on organizing scientific expertise to support the work of the Task Force. This includes a description of federal activity supporting Sandy recovery efforts, the role of the Task Force, and lessons learned from developing a science support function within the Task Force.

  7. IRAF: Lessons for Project Longevity

    NASA Astrophysics Data System (ADS)

    Fitzpatrick, M.

    2012-09-01

    Although sometimes derided as a product of the 80's (or more generously, as a legacy system), the fact that IRAF remains a productive work environment for many astronomers today is a testament to one of its core design principles, portability. This idea has meaning beyond a survey of platforms in use at the peak of a project's active development; for true longevity, a project must be able to weather completely unimagined OS, hardware, data, staffing and political environments. A lack of attention to the broader issues of portability, or the true lifespan of a software system (e.g. archival science may extend for years beyond a given mission, upgraded or similar instruments may be developed that require the same reduction/analysis techniques, etc) might require costly new software development instead of simple code re-use. Additionally, one under-appreciated benefit to having a long history in the community is the trust that users have established in the science results produced by a particular system. However a software system evolves architecturally, preserving this trust (and by implication, the applications themselves) is the key to continued success. In this paper, we will discuss how the system architecture has allowed IRAF to navigate the many changes in computing since it was first released. It is hoped that the lessons learned can be adopted by software systems being built today so that they too can survive long enough to one day earn the distinction of being called a legacy system.

  8. Lessons from modENCODE.

    Brown, James B; Celniker, Susan E

    2015-01-01

    The modENCODE (Model Organism Encyclopedia of DNA Elements) Consortium aimed to map functional elements-including transcripts, chromatin marks, regulatory factor binding sites, and origins of DNA replication-in the model organisms Drosophila melanogaster and Caenorhabditis elegans. During its five-year span, the consortium conducted more than 2,000 genome-wide assays in developmentally staged animals, dissected tissues, and homogeneous cell lines. Analysis of these data sets provided foundational insights into genome, epigenome, and transcriptome structure and the evolutionary turnover of regulatory pathways. These studies facilitated a comparative analysis with similar data types produced by the ENCODE Consortium for human cells. Genome organization differs drastically in these distant species, and yet quantitative relationships among chromatin state, transcription, and cotranscriptional RNA processing are deeply conserved. Of the many biological discoveries of the modENCODE Consortium, we highlight insights that emerged from integrative studies. We focus on operational and scientific lessons that may aid future projects of similar scale or aims in other, emerging model systems. PMID:26133010

  9. Four lessons in adaptive leadership.

    PubMed

    Useem, Michael

    2010-11-01

    The armed services have been in the business of leadership development much longer than the corporate world has. Today's military leaders need tools and techniques to face a fast-changing and unpredictable type of enemy--so the armed services train their officers in ways that build a culture of readiness and commitment. Business leaders need to foster an adaptive culture to survive and succeed, given that they, too, face unprecedented uncertainty--and new types of competitors. Michael Useem and his colleagues at the Wharton School incorporate exposure to military leadership into MBA and executive MBA programs. Highlights include direct contact in the classroom with leaders in the U.S. Army, the U.S. Marine Corps, and the Department of Defense, along with field-training exercises and battlefield visits. The programs are designed to help students connect viscerally to essential leadership lessons. Four are featured in the article: Meet the troops. Creating a personal link is crucial to leading people in challenging times. Make decisions. Making good and timely calls is the crux of leadership. Mission first. Focus on common purpose and eschew personal gain. Convey strategic intent. Make the objectives clear, but give people the freedom to execute on them in their own way. PMID:21049684

    For almost a quarter of a century, the Tevatron proton-antiproton collider was the centerpiece of the world's high energy physics program - beginning operation in December of 1985 until it was overtaken by LHC in 2011. The aim of the this unique scientific instrument was to explore the elementary particle physics reactions with center of mass collision energies of up to 1.96 TeV. The initial design luminosity of the Tevatron was 10{sup 30} cm{sup -2}s{sup -1}, however as a result of two decades of upgrades, the accelerator has been able to deliver 430 times higher luminosities to each of two high luminosity experiments, CDF and D0. Tevatron will be shut off September 30, 2011. The collider was arguably one of the most complex research instruments ever to reach the operation stage and is widely recognized for many technological breakthroughs and numerous physics discoveries. Below we briefly present the history of the Tevatron, major advances in accelerator physics, and technology implemented during the long quest for better and better performance. We also discuss some lessons learned from our experience.

  11. Huygens Highlights and lessons learned

    Ten years ago, on 14 January 2005, the Huygens Probe parachuted down to the surface of Titan, Saturn's largest moon. Huygens is part of the international Cassini/Huygens mission, a joint endeavor of NASA, the European Space Agency, and Agenzia Spaziale Italiana. Cassini/Huygens, comprising the NASA-provided Saturn Orbiter and the ESA-provided Huygens probe, was launched in October 1997. It arrived at Saturn in early July 2004. Huygens was released on the 3rd orbit around Saturn. It made measurements during the hypersonic entry, the descent, and for more than one hour on the surface. Unique in situ characterization of the atmosphere along the entry and descent trajectory and of the surface at the landing site was provided, revealing that many Earth-like processes were at work on Titan, a very fascinating methane world. Huygens observations also allowed inferring the ice crust thickness, hence an estimation of the depth of the icy crust/liquid water ocean interface. Huygens measurements are also used as ground-truth of the measurements made by the orbiter during Titan flybys. In this presentation, after a brief review of the major mission milestones, Huygens achievements are discussed in the context of the progress made in our understanding of Titan during the Cassini/Huygens mission. Lessons learned for the future in situ exploration of Titan are addressed. * Most of this work was performed while at ESA/ESTEC, Noordwijk, The Netherlands

  12. Drugging topoisomerases: lessons and challenges.

    PubMed

    Pommier, Yves

    2013-01-18

    Topoisomerases are ubiquitous enzymes that control DNA supercoiling and entanglements. They are essential during transcription and replication, and topoisomerase inhibitors are among the most effective and most commonly used anticancer and antibacterial drugs. This review consists of two parts. In the first part ("Lessons"), it gives background information on the catalytic mechanisms of the different enzyme families (6 different genes in humans and 4 in most bacteria), describes the "interfacial inhibition" by which topoisomerase-targeted drugs act as topoisomerase poisons, and describes clinically relevant topoisomerase inhibitors. It generalizes the interfacial inhibition principle, which was discovered from the mechanism of action of topoisomerase inhibitors, and discusses how topoisomerase inhibitors kill cells by trapping topoisomerases on DNA rather than by classical enzymatic inhibition. Trapping protein-DNA complexes extends to a novel mechanism of action of PARP inhibitors and could be applied to the targeting of transcription factors. The second part of the review focuses on the challenges for discovery and precise use of topoisomerase inhibitors, including targeting topoisomerase inhibitors using chemical coupling and encapsulation for selective tumor delivery, use of pharmacodynamic biomarkers to follow drug activity, complexity of the response determinants for anticancer activity and patient selection, prospects of rational combinations with DNA repair inhibitors targeting tyrosyl-DNA-phosphodiesterases 1 and 2 (TDP1 and TDP2) and PARP, and the unmet need to develop inhibitors for type IA enzymes.

    Bowyer, Stuart; Malina, Roger F.

    1986-01-01

    Line emission from the decay of fundamental particles, integrated over cosmological distances, can give rise to detectable spectral features in the diffuse astronomical background between 5 eV and 1 keV. Spectroscopic observations may allow these features to be separated from line emission from the numerous local sources of radiation. The current observational status and existing evidence for such features are reviewed. No definitive detections of nongalactic line features have been made. Several local sources of background mask the features at many wavelengths and confuse the interpretation of the data. No systematic spectral observations have been carried out to date. Upcoming experiments which can be expected to provide significantly better constraints on the presence of spectral features in the diffuse background from 5 eV to 1 keV are reviewed.

  14. Fluorescence Detection of Cosmic Ray Air Showers Between 1016.5 and 1018.5 eV with the Telescope Array Low Energy Extension (TALE)

    NASA Astrophysics Data System (ADS)

    Zundel, Zachary

    The Telescope Array (TA) Collaboration has completed construction of a low-energy extension to its Middle Drum telescope station. Ten new telescopes were added observing 32-59 degrees in elevation above the original telescopes. A graded array of scintillator detectors (SDs) with spacings of 400-600-1200 m is being installed in front of the telescope station. With these upgrades, the physics threshold will be lowered below 1016.5 eV. The TA Low Energy Extension (TALE) will explore the regime corresponding to the LHC center-of-mass energy. This is also the region where the transition from galactic to extra-galactic cosmic ray flux is suspected to occur. A brief overview of the physics is presented as well as a report on the progress toward measuring the cosmic ray spectrum between 1016.5 and 1018.5 eV.

    NASA has an established process for documenting and disseminating lessons learned from spaceflight missions and related activities. However, independent assessments of the NASA lessons learned process conducted in 2002, 2003, and 2011 have concluded that NASA programs and projects are failing to heed and apply these lessons learned. JPL recently completed implementation of a three-pronged approach to assure that NASA lessons learned get used by JPL spaceflight projects.

  16. From Lessons Learned Towards Disaster Reduction Measures

    NASA Astrophysics Data System (ADS)

    Scheer, S.

    2009-04-01

    Efforts have been undertaken over the past years in eliciting and collecting lessons as they could be derived from the outcome of natural disasters management. Lessons are viewed from various perspectives according to • the situation or triggering event which led to the disaster • the local or time-dependent characteristics of this situation and further analysed according to • their benefits • necessary actions to do in order to better implement a lesson. The explicit elicitation of all that information fosters the generation of good practices and the identification of bad practices. Hence the creation of appropriate measures concerning disaster reduction issues could be positively influenced. On the other hand, continuous efforts are undertaken in the field of establishing lists of disaster reduction measures for all major hazards. Those measures comprise both concrete techniques (e.g. a tool or a structure) and advisory techniques (teaching practices or procedural instructions). This paper gives an overview of ways to "produce" disaster reduction measures from lessons learned; moreover it will explain how context-dependent analysis of lessons can potentially lead to alterations of existing disaster reduction measures.

  17. Making a theory useful: lessons handed down.

    PubMed

    Higgins, E Tory

    2004-01-01

    What makes a theory useful? Whether one is evaluating and investigating one's own or another's theory, there are some useful lessons to keep in mind. One lesson is that the reason a "good" theory should be testable, be coherent, be economical, be generalizable, and explain known findings is that all of these characteristics serve the primary function of a theory--to be generative of new ideas and new discoveries. Other lessons concern how to develop a theory (whether one's own or an adopted one). One lesson is to know what the theory is and what it is not--don't make it into something else either by "improving" it or by unfairly dismissing it. Know the theory's domain of applicability--do test its limits but don't overextend it. Know when the theory makes a prediction and when it does not--know when it is simply silent. This article concludes by offering the metaphor that the lessons for developing a theory to make it useful have a lot in common with good parenting. For example: Neither spoil nor abuse the theory; neither neglect nor abandon it; support and nurture the theory; don't overprotect it but do defend it; be patient with the theory--don't push it too hard or too fast; and finally, don't forget to love and enjoy it.

    Among the principal objectives of the Phase 1 NASA/Mir program were for the United States to gain experience working with an international partner, to gain working experience in long-duration space flight, and to gain working experience in planning for and executing research on a long-duration space platform. The Phase 1 program was to provide the US early experience prior to the construction and operation of the International Space Station (Phase 2 and 3). While it can be argued that Mir and ISS are different platforms and that programmatically Phase 1 and ISS are organized differently, it is also clear that many aspects of operating a long-duration research program are platform independent. This can be demonstrated by a review of lessons learned from Skylab, a US space station program of the mid-1970s, many of which were again "learned" on Mir and are being "learned" on ISS. Among these are optimum crew training strategies, on-orbit crew operations, ground support, medical operations and crew psychological support, and safety certification processes. PMID:15835035

  16. MIS 5e sea level: up to what point can we use literature reviews to answer the most pressing questions on the Last Interglacial ice sheets?

    NASA Astrophysics Data System (ADS)

    Rovere, A.; Raymo, M. E.

    2014-12-01

    During MIS 5e (between ~128 and 116 kyr BP) greenhouse gas concentrations were comparable to pre-industrial levels, summer insolation was higher by ~10% at high latitudes and polar temperatures in both hemispheres were about 3-5 °C warmer than today. Sea level (SL) at this time has been a subject of numerous studies (and some debate) with ~1000 sites with MIS 5e sea level markers recognized worldwide. Recently, Kopp et al. (Nature, 2009) and Dutton & Lambeck (Science, 2012) analyzed worldwide datasets of sea level markers pertaining to the last interglacial. After accounting for GIA, they reached similar conclusions that eustatic (i.e., globally averaged) sea level (ESL) was between +5 and +9.4 m above modern during MIS 5e. Furthermore, Kopp et al. (Nature, 2009; GJI, 2013) suggest that sea level was not uniform during the LIG, but instead underwent at least two rapid oscillations including a rapid late 5e rise first proposed by Hearty et al. (QSR, 2007) and later by O'Leary et al. (Nat. Geo., 2013). Investigating the temporal and geographic variability of MIS 5e sea level opens new lines of research, in particular the possibility to fingerprint (Hay et al., QSR, 2014) the source of the proposed rapid ice sheet collapse near the end of the Last Interglacial. In this presentation we ask: can we use a database of published sea level estimates for this purpose? To answer this question, we built a relative sea level (RSL) database using RSLcalc 2.0; this is a relational database specifically designed to review relative sea level data points while keeping all the relevant information contained in the original publications. RSlcalc allows to estimate the measurement error (on the actual elevation of the SL feature), the error on the indicative range (the elevation range occupied by a sea level indicator) as well as the reference water level (the relationship between the marker and the former sea level). We show that the majority of published data have an accuracy of few

    The Marine Isotope sub-Stage 5e (~ 125 - 119 kyrs BP), the last interglacial period before the present, is believed to have been globally warmer (~ 2°C) than today. Studying this time interval might therefore provide insights into near future climate state given the ongoing climate change and global temperature increase. Of particular interest are the expected changes in polar ice cover. One important aspect of the cryosphere is sea-ice, which influences albedo, deep and surface water currents, and phytoplankton production, and thus affects the global climate system. To investigate whether changes in sea-ice cover occurred in the Southern Ocean close to Antarctica during Marine Isotope sub-Stage 5e dinoflagellate and diatom assemblages have been analyzed in core AS05-10, drilled in the continental slope off the Drygalski basin (Ross Sea) at a water depth of 2377 m. The core was drilled within the frame of the PNRA 2009/A2.01 project, an Italian project with a multidisciplinary approach, and covers the interval from Present to Marine Isotope Stage (MIS) 7. The core stratigraphy is based on diatom bioevents and on the climate cyclicity provided by the variations of the diatom assemblages. For this study we focused on the interval from MIS7 to MIS5. A strong reduction of sea-ice-loving diatom taxa with respect to open water-loving diatom taxa is observed during MIS5. In general the production of phytoplankton increases at the base of MIS5 and then slowly decreases. Dinoflagellate cysts, particularly heterotrophic species, are abundant during MIS5e only. The sea surface temperature reconstruction based on the TEX86L, a proxy based on lipid biomarkers produced by Thaumarcheota, shows a 4°C temperature increase from MIS6 to MIS5e. A slightly smaller temperature increase is observed at the onset of MIS7, but this stage is barren of heterotrophic dinoflagellates. All proxies together seem to indicate that the retreat of the summer sea-ice in the Ross Sea during MIS5e was

    The lack of scientific data concerning interglacials of the Pleistocene in the Arctic has been a major obstacle within the climate community. Study of the interglacials of Marine Isotope Stage(s) (MIS) 1, 5e, 11c and 31 in high latitudes is important to decoding Arctic sensitivity and providing us with a potential analogue for a future Arctic with climate change. Data from a sediment core recovered from Lake El'Gygytgyn in northeastern (NE) Russia gives a continuous, high-resolution record of the Arctic spanning the past 2.8 million years whilst recording these interglacials. The data was used to correlate simulated interglacial Arctic climate with Arctic climate derived from sediment core proxy studies. Here, we use a Global Circulation Model (GCM) with a coupled atmosphere and land-surface scheme complete with an interactive vegetation component to simulate marine isotope stages 1, 5e, 11c and 31 in the Arctic. GCM simulations of MIS 5e and 31 in the Arctic both show a warmer arctic climate that can be explained by high obliquity, high eccentricity, high CO2 (287 ppmv ,325 ppmv , respectively) and precession that aligns perihelion with boreal summer. Consequently, MIS 5e showed the greatest summer warming compared to the other interglacials and pre-industrial control. However, the distinctly higher values of mean temperature of the warmest month (MTWM) and annual precipitation during stage 11c cannot readily be explained by summer orbital forcings and greenhouse gas (GHG) concentrations. Montane forest is seen migrating northward in stages 1, 5e and 31 as the surface insolation increases and sea ice melts, whereas in 11c, the warmest of the interglacials, evergreen forest takes over and migrates pole ward toward the coast. Feedback from low albedo forest biome was studied and conclusions suggest the increase in temperature due to forest cover is insignificant in creating a significantly warm regional climate.

    Many lessons were learned during the development of the valves for the MC-1 engine. The purpose of this report is to focus on a variety of issues related to the engine valves and convey the lessons learned. This paper will not delve into detailed technical analysis of the components. None of the lessons learned are new or surprising, but simply reinforce the importance of addressing the details of the design early, at the component level. The Marshall Space Flight Center (MSFC), Huntsville, Alabama developed the MC-1 engine, a LOX / FW-1, 60,000 pound thrust engine. This engine was developed under the Low Cost Boost Technology office at MSFC and proved to be a very successful project for the MSFC Propulsion team and the various subcontractors working the development of the engine and its components.

    Three experiments revealed that music lessons promote sensitivity to emotions conveyed by speech prosody. After hearing semantically neutral utterances spoken with emotional (i.e., happy, sad, fearful, or angry) prosody, or tone sequences that mimicked the utterances' prosody, participants identified the emotion conveyed. In Experiment 1 (n=20), musically trained adults performed better than untrained adults. In Experiment 2 (n=56), musically trained adults outperformed untrained adults at identifying sadness, fear, or neutral emotion. In Experiment 3 (n=43), 6-year-olds were tested after being randomly assigned to 1 year of keyboard, vocal, drama, or no lessons. The keyboard group performed equivalently to the drama group and better than the no-lessons group at identifying anger or fear. PMID:15053726

    The PEP-II B-Factory collider ended the final phase of operation at nearly twice the design current and 4X the design luminosity. To highlight the evolution from the original conceptual design through to the 1.2E34 final machine we choose one example each from the broadband feedback and from the LLRF system. They illustrate the original design estimation missed some very significant details, and how in the course of PEP-II operation unexpected difficulties led to significant insights and new approaches which allowed higher machine performance. We present valuable 'lessons learned' which are of interest to designers of next generation feedback and impedance controlled LLRF systems.

    Finding solutions to thermal coating issues on the Deep Space Climate Observatory (DSCOVR) mission was a very challenging and unique endeavor. As a passive thermal control system, coatings provide the desired thermal, optical, and electrical charging properties, while surviving a harsh space environment. DSCOVR mission hardware was repurposed from the late 1990s satellite known as Triana. As a satellite that was shelved for over a decade, the coating surfaces consequently degraded with age, and became fairly outdated. Although the mission successfully launched in February 2015, there were unfamiliar observations and unanticipated issues with the coating surfaces during the revival phases of the project. For example, the thermal coatings on DSCOVR experienced particulate contamination and resistivity requirement problems, among other issues. While finding solutions to these issues, valuable lessons were learned in thermal coatings that may provide great insight to future spaceflight missions in similar situations.

The Uranium Trioxide (UO{sub 3}) Facility operated at the Hanford Site from 1952-1972, 1984-1988, and briefly in 1993. Both plants were ordered to permanent shutdown by the U.S. Department of Energy (DOE) in December 1992, thus initiating their deactivation phase. Deactivation is that portion of a facility`s life cycle that occurs between operations and final decontamination and decommissioning (D&D). This document details the history of events, and the lessons learned, from the time of the PUREX Stabilization Campaign in 1989-1990, through the end of the first full fiscal year (FY) of the deactivation project (September 30, 1994).

    Data warehouse projects are perceived to be risky and prone to failure due to many organizational and technical challenges. However, often iterative and lengthy processes of implementation of data warehouses at an enterprise level provide an opportunity for formative evaluation of these solutions. This paper describes lessons learned from successful development and implementation of the first phase of an enterprise data warehouse to support public health surveillance at British Columbia Centre for Disease Control. Iterative and prototyping approach to development, overcoming technical challenges of extraction and integration of data from large scale clinical and ancillary systems, a novel approach to record linkage, flexible and reusable modeling of clinical data, and securing senior management support at the right time were the main factors that contributed to the success of the data warehousing project.

    This EarthScope-funded project is a collaboration between high school science teachers and their students, undergraduate and graduate students, and faculty from California State University San Bernardino (CSUSB), University of Arizona, and the Southern California Earthquake Center (SCEC). As high school teachers and their students work alongside one another, they are exposed to and contribute to an authentic research process that will lead to publishable results. The scientific goal of this project is to measure plate tectonic movement within the San Bernardino mountain area and the Inland Empire region of Southern California utilizing the Global Positioning System (GPS). Teachers and high school students collected survey-mode GPS data from 11 sites (among a total of 25 sampled by the larger group of participants) during a 5-day campaign from July 14 -19, 2011. The information obtained will be useful for understanding and characterizing seismic hazards in that region of Southern California. To enhance this experience, all of the teachers and their students have been invited to present their results at the SCEC Annual Meeting in September 2011. As part of the classroom implementation phase of the program the teachers are introduced to the Lesson Study approach. Lesson Study is a professional development process where teachers systematically examine their practice with the goal of becoming more effective. This process centers on teachers working collaboratively on a small number of Research Lessons. First, they identify the areas where their students are encountering challenges in learning standards-based content. The challenging areas are identified through results from standardized exams (e.g. California Standards Tests) or other assessment tools. To address areas of difficulty the teachers develop, test, and improve an instructional experience that promotes student learning of that standards-based material. Lesson Study is different from "lesson planning" because

    Pupils' interest has been one of the major concerns in science education research because it can be seen as a gateway to more personalised forms of interest and motivation. However, methods to investigate situational interest in science teaching and learning are not broadly examined. This study compares the pupils' observed situational interest and their expressed situational interest. One class of Finnish fourth-graders (N = 22, age 9-10 years) participated in a heat transfer lesson. The lesson encompassed an interactive demonstration with a thermal camera, teacher-led discussions and the conduct and presentation of a collaborative inquiry task. Pupils expressed their interest levels (scale: 1 = very boring, 5 = very interesting) by using an electronic response system called a 'clicker'. The measurement took place 15 times during the lesson, with 1 measurement being just a rehearsal. The lesson was video recorded, and visible aspects of interest at the measurement time points were analysed. Reported and observational data were compared. In most cases, the observations did not yield data compatible with the pupils' own evaluations, indicating that most pupils' expressed interest is not easily interpreted through observation of their facial expressions and behaviour. In general, the interest of the group as a whole seems to diminish during the lesson. We argue that in order to maintain and increase pupils' interest, their evaluations should be taken into account in lesson planning. Video-based research might also be further enriched and validated by employing the participants' own expressions. The clicker is a suitable means of collecting primary pupils' experiences concerning their interest levels.

  10. Lessons from reproductive technology research.

    PubMed

    Seidel, George E

    2015-01-01

    A plethora of assisted reproductive technologies (ARTs) have come into routine use over the past half century. Some of these procedures were used much earlier experimentally. For example, Spallanzani performed artificial insemination in the dog in the late 1700s, and Heape did successful embryo transfer in the rabbit in 1890. Truly revolutionary tools and concepts important for ART occur at approximately half-decade intervals, for example, recombinant DNA procedures, transgenic technology, somatic cell nuclear transplantation, the polymerase chain reaction, and microRNAs. Similarly, obvious technologies sometimes take decades to come into practical use, such as sexing sperm and in vitro fertilization. I have categorized ARTs into five somewhat arbitrary categories in terms of perceived difficulty and feasibility: (a) when the seemingly possible turns out to be (essentially) impossible, e.g., homozygous, uniparental females; (b) when the seemingly impossible becomes possible, e.g., cryopreservation of embryos and transgenesis; (c) when the seemingly difficult turns out to be relatively easy, e.g., cryopreservation of sperm; (d) when the seemingly easy turns out to be difficult in key species, e.g., in vitro fertilization; and (e) when the seemingly difficult remains difficult, e.g., making true embryonic stem cells. The adage that "it is easy when you know how" applies repeatedly. The boundaries between what appears impossible/possible and difficult/easy change constantly owing to new tools and insights, one of the more important lessons learned. ARTs frequently are synergistic with each other. For example, somatic cell nuclear transplantation has made many kinds of experiments feasible that otherwise were impractical. Another example is that sexing sperm is useless for application without artificial insemination or in vitro fertilization. ARTs frequently are perceived as neat tricks and stimulate further thinking. This is useful for both teaching and research. PMID

Although not identical, there is a strong synergy in the study of these two objects. There is much the gamma-ray burst field can learn from the lessons of the more-developed supernova field, but the supernova field can also leam from new techniques developed for gamma-ray burst studies. Here I review some of the 'lessons learned' from these fields to help foster this synergy.

Inquiry-based lessons provide students with opportunities to independently investigate scientific concepts and tools. A general structure is developed ahead of time and minimal, careful guidance provided during the activity, but students are given as much freedom as possible to explore the concepts at their own pace. We designed our activity to help students learn to write flexible, re-usable, and readable code. I will describe the lesson structure we initially designed, as well as what aspects worked for our students (or didn't) and our experience leading the activity.

System dynamics modeling practice emphasize the need to keep models small so that they are manageable and understandable. This practice is generally reasonable and prudent; however, there are times that large SD models are necessary.

    During the period from 1977 to 1989, the Lawrence Livermore National Laboratory (LLNL) conducted a liquefied gaseous fuels spill effects program under the sponsorship of the US Department of Energy, Department of Transportation, Gas Research Institute and others. The goal of this program was to develop and validate tools that could be used to predict the effects of a large liquefied gas spill through the execution of large scale field experiments and the development of computer models to make predictions for conditions under which tests could not be performed. Over the course of the program, three series of LNG spill experiments were performed to study cloud formation, dispersion, combustion and rapid phase transition (RPT) explosions. The purpose of this paper is to provide an overview of this program, the lessons learned from 12 years of research as well as some recommendations for the future. The general conclusion from this program is that cold, dense gas related phenomena can dominate the dispersion of a large volume, high release rate spill of LNG especially under low ambient wind speed and stable atmospheric conditions, and therefore, it is necessary to include a detailed and validated description of these phenomena in computer models to adequately predict the consequences of a release. Specific conclusions include: * LNG vapor clouds are lower and wider than trace gas clouds and tend to follow the downhill slope of terrain due to dampened vertical turbulence and gravity flow within the cloud. Under low wind speed, stable atmospheric conditions, a bifurcated, two lobed structure develops. * Navier-Stokes models provide the most complete description of LNG dispersion, while more highly parameterized Lagrangian models were found to be well suited to emergency response applications. * The measured heat flux from LNG vapor cloud burns exceeded levels necessary for third degree burns and were large enough to ignite most flammable materials. * RPTs are of two

  19. Plumes on Enceladus: Lessons for Europa?

    NASA Astrophysics Data System (ADS)

    Nimmo, F.

    2014-12-01

    The possible detection of a water vapour plume on Europa [1] suggests resemblances to Enceladus, a cryovolcanically active satellite [2]. How does this activity work, and what lesson does Enceladus have for plumes on Europa? The inferred vapour column densities of the Europa [1] and Enceladus [3] plumes are similar, but the inferred velocity and mass flux of the former are higher. At Enceladus, the inferred plume strength is modulated by its orbital position [4,5], suggesting that tides opening and closing cracks control the eruption behaviour [6,7]. An additional source of stress potentially driving eruptions is the effect of slow freezing of the ice shell above[7,8]. The original detection of the Europa plume was close to apocentre, when polar fractures are expected to be in tension [1]. Follow-up observations at the same orbital phase did not detect a plume [9], although the Galileo E12 magnetometer data may provide evidence for an earlier plume [Khurana, pers. comm.]. One possible explanation for the plume's disappearance is that longer-period tidal effects are playing a role; there are hints of similar secular changes in the Enceladus data [4,5]. Another is that detectability of the Europa plumein the aurora observations also depends on variations in electron density (which affects the UV emission flux) [9]. Or it may simply be that eruptive activity on Europa is highly time-variable, as on Io. At Enceladus, the plume scale height is independent of orbital position and plume brightness [5]. This suggests that the vapour velocity does not depend on crack width, consistent with supersonic flow through a near-surface throat. The large scale height inferred for the Europa plume likewise suggests supersonic behaviour. Continuous fallback of solid plume material at Enceladus affects both the colour [10] and surface texture [2] of near-polar regions. Less frequent plume activity would produce subtler effects; whether the sparse available imagery at Europa [11

  20. Lessons from accretion disks in cataclysmic variables

    NASA Astrophysics Data System (ADS)

    Horne, Keith

    1998-04-01

    We survey recent progress in the interpretation of observations of cataclysmic variables, whose accretion disks are heated by viscous dissipation rather than irradiation. Many features of standard viscous accretion disk models are confirmed by tomographic imaging studies of dwarf novae. Eclipse maps indicate that steady disk temperature structures are established during outbursts. Doppler maps of double-peaked emission lines suggest disk chromospheres heated by magnetic activity. Gas streams impacting on the disk rim leave expected signatures both in the eclipses and emission lines. Doppler maps of dwarf nova IP Peg at the beginning of an outburst show evidence for tidally-induced spiral shocks. While enjoying these successes, we must still face up to the dreaded ``SW Sex syndrome'' which afflicts most if not all cataclysmic variables in high accretion states. The anomalies include single-peaked emission lines with skewed kinematics, flat temperature-radius profiles, shallow offset line eclipses, and narrow low-ionization absorption lines at phase 0.5. The enigmatic behavior of AE Aqr is now largely understood in terms of a magnetic propeller model in which the rapidly spinning white dwarf magnetosphere expels the gas stream out of the system before an accretion disk can form. A final piece in this puzzle is the realization that an internal shock zone occurs in the exit stream at just the right place to explain the anomalous kinematics and violent flaring of the single-peaked emission lines. Encouraged by this success, we propose that disk-anchored magnetic propellers operate in the high accretion rate systems afflicted by the SW Sex syndrome. Magnetic fields anchored in the Keplerian disk sweep forward and apply a boost that expels gas stream material flowing above the disk plane. This working hypothesis offers a framework on which we can hang all the SW Sex anomalies. The lesson for theorists is that magnetic links appear to be transporting energy and angular

    Branching ratios and the kinetic energy released in the various fragmentation channels of energy selected N2O+ (15-20.5 eV) were investigated by the technique of threshold photoelectron-photoion coincidence. Pulsed synchrotron radiation from ACO, Orsay's storage ring, dispersed by a monochromator, was used as a photon source. Threshold electrons were energy selected on the basis of angular and temporal discrimination against energetic electrons. The energy region below 16.388 eV and the ? state were investigated in detail. Below the ? state the most abundant fragment ion is O+, while above the ? state NO+ dominates. Results for the ? and ? states are also reported.

  7. Restoring Forest Landscapes: Important Lessons Learnt

    NASA Astrophysics Data System (ADS)

    Mansourian, Stephanie; Vallauri, Daniel

    2014-02-01

    Forest restoration at large scales, or landscapes, is an approach that is increasingly relevant to the practice of environmental conservation. However, implementation remains a challenge; poor monitoring and lesson learning lead to similar mistakes being repeated. The World Wildlife Fund (WWF), the global conservation organization, recently took stock of its 10 years of implementation of forest landscape restoration. A significant body of knowledge has emerged from the work of the WWF and its partners in the different countries, which can be of use to the wider conservation community, but for this to happen, lessons need to be systematically collected and disseminated in a coherent manner to the broader conservation and development communities and, importantly, to policy makers. We use this review of the WWF's experiences and compare and contrast it with other relevant and recent literature to highlight 11 important lessons for future large-scale forest restoration interventions. These lessons are presented using a stepwise approach to the restoration of forested landscapes. We identify the need for long-term commitment and funding, and a concerted and collaborative effort for successful forest landscape restoration. Our review highlights that monitoring impact within landscape-scale forest restoration remains inadequate. We conclude that forest restoration within landscapes is a challenging yet important proposition that has a real but undervalued place in environmental conservation in the twenty-first century.
