Sample records for tertiary t-r transitions

  1. Spontaneous quaternary and tertiary T-R transitions of human hemoglobin in molecular dynamics simulation.

    Directory of Open Access Journals (Sweden)

    Jochen S Hub


    Full Text Available We present molecular dynamics simulations of unliganded human hemoglobin (Hb A under physiological conditions, starting from the R, R2, and T state. The simulations were carried out with protonated and deprotonated HC3 histidines His(beta146, and they sum up to a total length of 5.6 micros. We observe spontaneous and reproducible T-->R quaternary transitions of the Hb tetramer and tertiary transitions of the alpha and beta subunits, as detected from principal component projections, from an RMSD measure, and from rigid body rotation analysis. The simulations reveal a marked asymmetry between the alpha and beta subunits. Using the mutual information as correlation measure, we find that the beta subunits are substantially more strongly linked to the quaternary transition than the alpha subunits. In addition, the tertiary populations of the alpha and beta subunits differ substantially, with the beta subunits showing a tendency towards R, and the alpha subunits showing a tendency towards T. Based on the simulation results, we present a transition pathway for coupled quaternary and tertiary transitions between the R and T conformations of Hb.

    Louro, S.R.W.; Ribeiro, P.C.; Bemski, G.


    EPR spectra of nitrosil-hemes were used to study the quaternary structure of hemoglobin. Human adult hemoglobin has been titrated with nitric oxide at pH 7.0 and 25 0 C. After the equilibration of NO among the α and β subunits the samples were frozen for EPR measurements. The spectra were fitted by linear combinations of three standard signals: the first arising from NO - β hemes and the other two arising from NO - α hemes of molecules in the high and low affinity conformations. The fractional amounts of α subunits exhibiting the high affinity spectrum fitted the two-state model with L = 7 x 10 6 , and csup(α) sub(NO) and csup(β) sub(NO) approximately 0.01. Hemoglobin has been marked with nitric oxide at one chain using low-saturation amounts of nitric oxide. The EPR spectra were studied as a function of oxygen saturation. Linear combinations of the three standard signals above fitted these spectra. The fractions of molecules exhibiting the high affinity spectrum fitted the two-state model with L = 7 x 10 6 , csub(O 2 ) = 0.0033 and csup(α) sub(NO) = 0.08, instead of csup(α) sub(NO) = 0.01.Thus, the two state model is not adequate to describe the conformational transition of these hybrids. The results are evidence of the nonequivalence between oxygen and nitric oxide as ligands. (Author) [pt

  8. Evolving the Design of a Mobile Application to Support Transition to Tertiary Education

    Directory of Open Access Journals (Sweden)

    Yu Zhao


    Full Text Available Students’ transition to tertiary education plays a critical role in their overall post-secondary experience. Even though educational institutions have designed and implemented various transition support programs, most of them still struggle to collect detailed information and provide tailored and timely support to students. With the high adoption rate of smart phones among university students, mobile applications can be used as a platform to provide personalized support throughout the transition, which has the potential to address the shortcomings of existing programs. Moreover, the use of mobile applications to support the transition to tertiary education can benefit from emerging techniques to design applications to support individuals through transition processes. In this paper, we present the design and development process of myUniMate, a mobile application that allows students to track and reflect on information from multiple aspects of their university lives. The paper describes the user-centered design approach used in the design, the implementation process, and how the initial version evolved based on our previous study. We conducted a 4-week field trial with first year university students to validate our design.

  9. Tertiary-amine-containing thermo- and pH-sensitive hydrophilic ABA triblock copolymers: effect of different tertiary amines on thermally induced sol-gel transitions. (United States)

    Henn, Daniel M; Wright, Roger A E; Woodcock, Jeremiah W; Hu, Bin; Zhao, Bin


    This Article reports on the synthesis of a series of well-defined, tertiary-amine-containing ABA triblock copolymers, composed of a poly(ethylene oxide) (PEO) central block and thermo- and pH-sensitive outer blocks, and the study of the effect of different tertiary amines on thermally induced sol-gel transition temperatures (T(sol-gel)) of their 10 wt % aqueous solutions. The doubly responsive ABA triblock copolymers were prepared from a difunctional PEO macroinitiator by atom transfer radical polymerization of methoxydi(ethylene glycol) methacrylate and ethoxydi(ethylene glycol) methacrylate at a feed molar ratio of 30:70 with ∼5 mol % of either N,N-diethylaminoethyl methacrylate (DEAEMA), N,N-diisopropylaminoethyl methacrylate, or N,N-di(n-butyl)aminoethyl methacrylate. The chain lengths of thermosensitive outer blocks and the molar contents of tertiary amines were very similar for all copolymers. Using rheological measurements, we determined the pH dependences of T(sol-gel) of 10 wt % aqueous solutions of these copolymers in a phosphate buffer. The T(sol-gel) versus pH curves of all polymers exhibited a sigmoidal shape. The T(sol-gel) increased with decreasing pH; the changes were small on both high and low pH sides. At a specific pH, the T(sol-gel) decreased with increasing the hydrophobicity of the tertiary amine, and upon decreasing pH the onset pH value for the T(sol-gel) to begin to increase noticeably was lower for the more hydrophobic tertiary amine-containing copolymer. In addition, we studied the effect of different tertiary amines on the release behavior of FITC-dextran from 10 wt % micellar gels in an acidic medium at 37 and 27 °C. The release profiles for three studied hydrogels at 37 °C were essentially the same, suggesting that the release was dominated by the diffusion of FITC-dextran. At 27 °C, the release was significantly faster for the DEAEMA-containing copolymer, indicating that both diffusion and gel dissolution contributed to the

  10. Homologation of methanol catalyzed by transition metal complexes in the presence of tertiary amines

    Energy Technology Data Exchange (ETDEWEB)

    Tanaka, Masato; Ogata, Ikuei


    This paper describes the homologation of methanol by transition metal carbonyl catalysts in the presence of tertiary amines. Methanol was reacted with amine using a catalyst at 180/sup 0/C under 100 atm in the atmosphere of CO and H/sub 2/ mixed at the ratio of 4 in an autoclave. The reaction activities and selectivities of ethanol using iron carbonyl and Co carbonyl catalysts are superior. Only the iron catalyst was used hereafter because phosphine is required for the latter catalyst. N-methyl- piperidine, a cyclic amine, is superior to the other amines. The selectivity of ethanol is higher under higher partial pressure of H/sub 2/ and lower partial pressure of CO. The conversion rate is optimum at 180/sup 0/ and it goes down with increasing the temperature from it. Since the selectivity is markedly decreased with increasing amine, the reaction activity must be balanced with the amount of amine. The presence of solvent affects it. (3 figs, 6 tabs, 15 refs)

  11. Tunable differentiation of tertiary C-H bonds in intramolecular transition metal-catalyzed nitrene transfer reactions. (United States)

    Corbin, Joshua R; Schomaker, Jennifer M


    Metal-catalyzed nitrene transfer reactions are an appealing and efficient strategy for accessing tetrasubstituted amines through the direct amination of tertiary C-H bonds. Traditional catalysts for these reactions rely on substrate control to achieve site-selectivity in the C-H amination event; thus, tunability is challenging when competing C-H bonds have similar steric or electronic features. One consequence of this fact is that the impact of catalyst identity on the selectivity in the competitive amination of tertiary C-H bonds has not been well-explored, despite the potential for progress towards predictable and catalyst-controlled C-N bond formation. In this communication, we report investigations into tunable and site-selective nitrene transfers between tertiary C(sp 3 )-H bonds using a combination of transition metal catalysts, including complexes based on Ag, Mn, Rh and Ru. Particularly striking was the ability to reverse the selectivity of nitrene transfer by a simple change in the identity of the N-donor ligand supporting the Ag(i) complex. The combination of our Ag(i) catalysts with known Rh 2 (ii) complexes expands the scope of successful catalyst-controlled intramolecular nitrene transfer and represents a promising springboard for the future development of intermolecular C-H N-group transfer methods.

  15. Transition from tube feeding to oral feeding: experience in a tertiary care paediatric cardiology unit. (United States)

    Shine, Anne Marie; Finn, Daragh Gerard; Allen, Noeleen; McMahon, Colin J


    Home enteral tube feeding (HETF) is imperative for many infants and children with congenital heart disease (CHD). Tube weaning (TW) facilitates the progression from tube feeding to oral diet. There is limited literature on TW practices, protocols and success for children with CHD that have been tube fed. The objective of this study is to assess the process of weaning HETF in a tertiary referral centre for paediatric CHD. Specifically, we aimed to assess the duration of HETF, duration of TW and the interventions involved. We retrospectively reviewed the medical and dietetic records of all infants and children that were successfully weaned off HETF over a 12-month period from January 2015 to December 2015. There were 30 children included in the study, 9 boys and 21 girls. The diagnoses included 15 septal defects, 8 univentricular diagnosis and other diagnoses in 7 children. The median age at initiation of enteral tube feeding was 45 days (range 2-169). The median duration to wean from enteral tube feeding was 52 days (range 2-359). Number of dietetic consults required for successful TW varied among patients, median 5 (range 2-23). The number of days required for successful TW was associated with age and duration on HETF. Dietetic interventions included discontinuation of nutrient dense feeds, altering feed schedule and reduction of feed volume. Weaning HETF is possible in the outpatient setting. Early and frequent dietetic intervention is recommended to ensure prompt discontinuation of HETF when appropriate.

  16. Improving care planning and coordination for service users with medical co-morbidity transitioning between tertiary medical and primary care services. (United States)

    Cranwell, K; Polacsek, M; McCann, T V


    WHAT IS KNOWN ON THE SUBJECT?: Mental health service users with medical co-morbidity frequently experience difficulties accessing and receiving appropriate treatment in emergency departments. Service users frequently experience fragmented care planning and coordinating between tertiary medical and primary care services. Little is known about mental health nurses' perspectives about how to address these problems. WHAT THIS PAPER ADDS TO EXISTING KNOWLEDGE?: Emergency department clinicians' poor communication and negative attitudes have adverse effects on service users and the quality of care they receive. The findings contribute to the international evidence about mental health nurses' perspectives of service users feeling confused and frustrated in this situation, and improving coordination and continuity of care, facilitating transitions and increasing family and caregiver participation. Intervention studies are needed to evaluate if adoption of these measures leads to sustainable improvements in care planning and coordination, and how service users with medical co-morbidity are treated in emergency departments in particular. WHAT ARE THE IMPLICATIONS FOR PRACTICE?: Effective planning and coordination of care are essential to enable smooth transitions between tertiary medical (emergency departments in particular) and primary care services for service users with medical co-morbidity. Ongoing professional development education and support is needed for emergency department clinicians. There is also a need to develop an organized and systemic approach to improving service users' experience in emergency departments. Introduction Mental health service users with medical co-morbidity frequently experience difficulties accessing appropriate treatment in medical hospitals, and often there is poor collaboration within and between services. Little is known about mental health nurses' perspectives on how to address these problems. Aim To explore mental health nurses

  17. Mass Wasting during the Cretaceous/Tertiary Transition in the North Atlantic: Relationship to the Chicxulub Impact? (United States)

    Mateo, Paula; Keller, Gerta; Adatte, Thierry; Spangenberg, Jorge


    Deep-sea sections in the North Atlantic are claimed to contain the most complete sedimentary records and ultimate proof that the Chicxulub impact is Cretaceous-Tertiary boundary (KTB) in age and caused the mass extinction. A multi-disciplinary study of North Atlantic DSDP Sites 384, 386 and 398, based on high-resolution planktonic foraminiferal biostratigraphy, carbon and oxygen stable isotopes, clay and whole-rock mineralogy and granulometry, reveals the age, stratigraphic completeness and nature of sedimentary disturbances. Results show a major KTB hiatus at Site 384 with zones CF1, P0 and P1a missing, spanning at least ~540 ky, similar to other North Atlantic and Caribbean localities associated with tectonic activity and Gulf Stream erosion. At Sites 386 and 398, discrete intervals of disturbed sediments with mm-to-cm-thick spherule layers have previously been interpreted as KTB age impact-generated earthquakes destabilizing continental margins prior to settling of impact spherules. However, improved age control based on planktonic foraminifera indicates deposition in the early Danian zone P1a(2) (upper Parvularugoglobigerina eugubina zone) more than 100 ky after the KTB. At Site 386, two intervals of white chalk contain very small (winnowing via distal turbidites. At Site 398, convoluted red to tan sediments with early Danian and reworked Cretaceous species represent slumping of shallow water sediments as suggested by dominance of mica and low smectite compared to in situ deposition. We conclude that mass wasting was likely the result of earthquakes associated with increased tectonic activity in the Caribbean and the Iberian Peninsula during the early Danian well after the Chicxulub impact.

  18. Retrospective analysis of patients undergoing bowel transit reconstruction in a tertiary referral hospital of São Paulo's east side

    Directory of Open Access Journals (Sweden)

    Isaac José Felippe Corrêa Neto


    Full Text Available Introduction: The morbidity and mortality of patients undergoing bowel transit reconstruction reach significant values. Perhaps this and other factors could explain why 30–60% of patients end up with definitive ostomies, even those with initially temporary ostomies, due to the procedure risks. Objective: To analyze retrospectively the medical records of patients undergoing bowel transit reconstruction in one of the SUS referral hospitals in São Paulo from October 2008 to December 2011. Results: The mean age of our patients was 53.9 years and 54% of those 100 patients studied between October 2008 and December 2011 had significant comorbidity. The indication for creating an initial ostomy was malignancy in 43%, and the mean stoma duration 14.3 months. The mortality rate was 6%. Conclusion: Although the bowel transit reconstruction is a procedure quite desired by patients, its indication should be carefully evaluated, with an appropriate consent from the patient. Resumo: Introdução: A morbi-mortalidade de pacientes submetidos à reconstrução de trânsito intestinal alcança valores significativos e, por esse e outros fatores, talvez se explique o fato que de 30 a 60% dos portadores de ostomia intestinal terminal passam a possuí-la de maneira definitiva, apesar de, na maior parte das vezes, ela ser realizada como procedimento provisório com o argumento de maior segurança do paciente. Objetivo: Analisar retrospectivamente os dados de prontuário de pacientes submetidos à reconstrução de trânsito intestinal em um dos hospitais de referência do SUS na cidade de São Paulo no período de outubro de 2008 a dezembro de 2011. Resultados: A média de idade dos pacientes foi de 53,9 anos e 54% dos 100 pacientes estudados no período de outubro de 2008 e dezembro de 2011 padeciam de alguma comorbidade. A indicação para confecção da ostomia inicial decorreu de doença maligna em 43% e o tempo médio de permanência com o estoma foi de 14

    The principal research effort for Year 1 of the project has been T-R cycle characterization and modeling. The research focus for the first nine (9) months of Year 1 was on outcrop study, well log analysis, seismic interpretation and data integration and for the remainder of the year the emphasis has been on T-R cycle model development. Information regarding the characteristics of T-R cycles has been assembled from the study of outcrops, from well log analyses, and from seismic reflection interpretation. From these studies, stratal boundaries separating T-R cycles have been found to be useful for the recognition and delineation of these cycles. The key stratal surfaces include subaerial unconformities, shoreface ravinement surfaces, transgressive surfaces, surfaces of maximum regression, and surfaces of maximum transgression. These surfaces can be identified and mapped in surface exposures and can be recognized in well log signatures and seismic reflection profiles as discontinuities. The findings from the study of outcrop, well log, and seismic reflection data are being integrated into a database for use in constructing a model for T-R cycle development.

  4. T-R Cycle Characterization and Imaging: Advanced Diagnostic Methodology for Petroleum Reservoir and Trap Detection and Delineation

    Energy Technology Data Exchange (ETDEWEB)

    Ernest A. Mancini


    Characterization of stratigraphic sequences (T-R cycles or sequences) included outcrop studies, well log analysis and seismic reflection interpretation. These studies were performed by researchers at the University of Alabama, Wichita State University and McGill University. The outcrop, well log and seismic characterization studies were used to develop a depositional sequence model, a T-R cycle (sequence) model, and a sequence stratigraphy predictive model. The sequence stratigraphy predictive model developed in this study is based primarily on the modified T-R cycle (sequence) model. The T-R cycle (sequence) model using transgressive and regressive systems tracts and aggrading, backstepping, and infilling intervals or sections was found to be the most appropriate sequence stratigraphy model for the strata in the onshore interior salt basins of the Gulf of Mexico to improve petroleum stratigraphic trap and specific reservoir facies imaging, detection and delineation. The known petroleum reservoirs of the Mississippi Interior and North Louisiana Salt Basins were classified using T-R cycle (sequence) terminology. The transgressive backstepping reservoirs have been the most productive of oil, and the transgressive backstepping and regressive infilling reservoirs have been the most productive of gas. Exploration strategies were formulated using the sequence stratigraphy predictive model and the classification of the known petroleum reservoirs utilizing T-R cycle (sequence) terminology. The well log signatures and seismic reflector patterns were determined to be distinctive for the aggrading, backstepping and infilling sections of the T-R cycle (sequence) and as such, well log and seismic data are useful for recognizing and defining potential reservoir facies. The use of the sequence stratigraphy predictive model, in combination with the knowledge of how the distinctive characteristics of the T-R system tracts and their subdivisions are expressed in well log patterns

  7. Secondary and tertiary hyperparathyroidism. (United States)

    Jamal, Sophie A; Miller, Paul D


    We reviewed the etiology and management of secondary and tertiary hyperparathyroidism. Secondary hyperparathyroidism is characterized by an increase in parathyroid hormone (PTH) that is appropriate and in response to a stimulus, most commonly low serum calcium. In secondary hyperparathyroidism, the serum calcium is normal and the PTH level is elevated. Tertiary hyperparathyroidism is characterized by excessive secretion of PTH after longstanding secondary hyperparathyroidism, in which hypercalcemia has ensued. Tertiary hyperparathyroidism typically occurs in men and women with chronic kidney disease usually after kidney transplant. The etiology and treatment of secondary hyperparathyroidism is relatively straightforward whereas data on the management of tertiary hyperparathyroidism is limited to a few small trials with short follow-up.

    International Nuclear Information System (INIS)

    Barlier-Salsi, A.; Salsi, S.


    A first version of C.a.t.R.a.y.o.n. was therefore developed with the aim of making available a set of general and technical data on optical radiation sources to users and prevention specialists. Its main aim is to provide knowledge of hazards inherent in an optical radiation source under conditions defined by users. A first version of C.a.t.R.a.y.o.n. with 5 data bases of approximately 400 optical radiation sources, allowed assessment of the hazards produced by one source at a workstation. The new version considers several sources and takes in account their spatial intensity distribution. It permits: assessment of exposure at fixed or moving workstations, performance of hazard mapping in a determined working area, definition or proposal of efficient personal protection or group protection by adding filters in front of sources, editing an analysis report containing all results. A database of around a hundred protective filters now complements the source database. (N.C.)

    We propose general f(R,T,R{sub μν}T{sup μν}) theory as generalization of covariant Hořava-like gravity with dynamical Lorentz symmetry breaking. FRLW cosmological dynamics for several versions of such theory is considered. The reconstruction of the above action is explicitly done, including the numerical reconstruction for the occurrence of ΛCDM universe. De Sitter universe solutions in the presence of non-constant fluid are also presented. The problem of matter instability in f(R,T,R{sub μν}T{sup μν}) gravity is discussed.

  15. Building bridges: an interpretive phenomenological analysis of nurse educators' clinical experience using the T.R.U.S.T. Model for inclusive spiritual care. (United States)

    Scott Barss, Karen


    Educating nurses to provide evidence-based, non-intrusive spiritual care in today's pluralistic context is both daunting and essential. Qualitative research is needed to investigate what helps nurse educators feel more prepared to meet this challenge. This paper presents findings from an interpretive phenomenological analysis of the experience of nurse educators who used the T.R.U.S.T. Model for Inclusive Spiritual Care in their clinical teaching. The T.R.U.S.T. Model is an evidence-based, non-linear resource developed by the author and piloted in the undergraduate nursing program in which she teaches. Three themes are presented: "The T.R.U.S.T. Model as a bridge to spiritual exploration"; "blockades to the bridge"; and "unblocking the bridge". T.R.U.S.T. was found to have a positive influence on nurse educators' comfort and confidence in the teaching of spiritual care. Recommendations for maximizing the model's positive impact are provided, along with "embodied" resources to support holistic teaching and learning about spiritual care.

  16. Spectroscopic markers of the TR quaternary transition in human hemoglobin. (United States)

    Schirò, Giorgio; Cammarata, Marco; Levantino, Matteo; Cupane, Antonio


    In this work, we use a sol-gel protocol to trap and compare the R and T quaternary states of both the deoxygenated (deoxyHb) and carbonmonoxide (HbCO) derivatives of human hemoglobin. The near infrared optical absorption band III and the infrared CO stretching band are used to detect the effect of quaternary structure on the spectral properties of deoxyHb and HbCO; comparison with myoglobin allows for an assessment of tertiary and quaternary contributions to the measured band shifts. The RT transition is shown to cause a blue shift of the band III by approximately 35 cm(-1) for deoxyHb and a red shift of the CO stretching band by only approximately 0.3 cm(-1) for HbCO. This clearly shows that quaternary structure changes are transmitted to the heme pocket and that effects on deoxyHb are much larger than on HbCO, at least as far as the band energies are concerned. Experiments performed in the ample temperature interval of 300-10K show that the above quaternary structure effects are "static" and do not influence the dynamic properties of the heme pocket, at least as probed by the temperature dependence of band III and of the CO stretching band. The availability of quaternary structure sensitive spectroscopic markers and the quantitative measurement of the quaternary structure contribution to band shifts will be of considerable help in the analysis of flash-photolysis experiments on hemoglobin. Moreover, it will enable one to characterize the dynamic properties of functionally relevant hemoglobin intermediates and to study the kinetics of both the T-->R and R-->T quaternary transitions through time-resolved spectroscopy.

  17. Tertiary climatic fluctuations and methods of analysis of tertiary floras (United States)

    Wolfe, J.A.


    On theoretical grounds, an analysis of the physiognomy of a Tertiary leaf assemblage is more direct and reliable than a circuitous floristic analysis in assigning thermal regimes to fossil assemblages. Using primarily foliar physiognomy and secondarily floristic composition, it can be shown that: (1) some middle latitude Tertiary assemblages probably lived under meteoroligically tropical climates; (2) a major and rapid climatic deterioration occurred in the Oligocene; and (3) a major climatic fluctuation probably occurred in the Late Eocene. These analyses thus substantiate the conclusions of several other paleobotanists regarding climatic fluctuations. Recent criticisms of these analyses are shown to be invalid and to be based largely on misinterpretations. ?? 1971.

    Yousaf, Z.; Bhatti, M.Z.; Farwa, Ume [University of the Punjab, Department of Mathematics, Lahore (Pakistan)


    The aim of this paper is to investigate the stable/unstable regimes of the non-static anisotropic filamentary stellar models in the framework of f(R,T,R{sub μν}T{sup μν}) gravity. We construct the field equations and conservation laws in the perspective of this model of gravity. The perturbation scheme is applied to the analysis of the behavior of a particular f(R,T,R{sub μν}T{sup μν}) cosmological model on the evolution of cylindrical system. The role of the adiabatic index is also checked in the formulations of the instability regions. We have explored the instability constraints in the Newtonian and post-Newtonian limits. Our results reinforce the significance of the adiabatic index and dark source terms in the stability analysis of celestial objects in modified gravity. (orig.)

  20. Impact of Clostridium difficile infection caused by the NAP1/RT027 strain on severity and recurrence during an outbreak and transition to endemicity in a Mexican tertiary care center

    Directory of Open Access Journals (Sweden)

    Karla María Tamez-Torres


    Full Text Available Objectives: To describe the clinical characteristics, outcomes, and factors associated with Clostridium difficile infection (CDI due to ribotype 027 (RT027 and recurrence, including an outbreak period, with transition to endemicity. Methods: A case–control study was performed. Clinical and demographic data were collected for patients with CDI during the period January 2008 to December 2015. Ribotyping of the isolates and PCR for toxin A, B, and binary were performed. Results: Among 324 episodes of CDI, 27.7% were caused by RT027. Previous fluoroquinolone use (odds ratio (OR 1.79, 95% confidence interval (CI 1.01–3.17, previous gastrointestinal endoscopy (OR 2.17, 95% CI 1.29–3.65, chemotherapy (OR 0.43, 95% CI 0.19–0.95, and total enteral nutrition (OR 0.42, 95% CI 0.18–0.97 were associated with RT027. Age >65 years (OR 2.05, 95% CI 1.02–4.10, severe initial episode (OR 3.35, 95% CI 1.60–6.15, previous proton pump inhibitor use (OR 2.34, 95% CI 1.15–4.74, and continued fluoroquinolones (OR 3.08, 95% CI 1.11–8.51 were associated with recurrence. Among the non-RT027, 59.8% were not assigned by the ribotyping database and 50.7% presented binary toxin. Conclusions: In this population, CDI due to the RT027 strain was not associated with poorer outcomes. This study reinforces the importance of avoiding fluoroquinolones and PPIs to prevent recurrences. The presence of virulence factors among non-RT027 C. difficile strains underscores the importance of performing molecular epidemiology surveillance.

  1. 3 Tesla MRI of patients with a vagus nerve stimulator: initial experience using a T/R head coil under controlled conditions. (United States)

    Gorny, Krzysztof R; Bernstein, Matt A; Watson, Robert E


    To assess safety of clinical MRI of the head in patients with implanted model 100, 102, and 103 vagus nerve stimulation (VNS) Therapy Systems (Cyberonics, Inc., Houston, TX) in 3.0 Tesla MRI (GE Healthcare, Milwaukee, WI). The distributions of the radiofrequency B(1) (+)-field produced by the clinically used transmit/receive (T/R) head coil (Advanced Imaging Research Incorporated, Cleveland, OH) and body coil were measured in a head and shoulders phantom. These measurements were supplemented by temperature measurements on the lead tips and the implantable pulse generator (IPG) of the VNS devices in a head and torso phantom with the same two coils. Clinical 3T MRI head scans were then acquired under highly controlled conditions in a series of 17 patients implanted with VNS. Phantom studies showed only weak B(1) (+) fields at the location of the VNS IPG and leads for MRI scans using the T/R head coil. The MRI-related heating on a VNS scanned in vitro at 3T was also found to be minimal (0.4-0.8 degrees C at the leads, negligible at the IPG). The patient MRI examinations were completed successfully without any adverse incidents. No patient reported any heating, discomfort, or any other unusual sensation. Safe clinical MRI head scanning of patients with implanted VNS is shown to be feasible on a GE Signa Excite 3T MRI system using one specific T/R head coil. These results apply to this particular MRI system configuration. Extrapolation or generalization of these results to more general or less controlled imaging situations without supporting data of safety is highly discouraged.

  3. Parathyroid carcinoma in tertiary hyperparathyroidism. (United States)

    Kim, Byung Seup; Ryu, Han Suk; Kang, Kyung Ho; Park, Sung Jun


    Parathyroid carcinoma is a rare disease of unknown etiology. This study presents a case of parathyroid carcinoma in a patient with tertiary hyperparathyroidism. Despite a successful kidney transplantation, the intact parathyroid hormone (iPTH) level of the patient was elevated consistently and could not be controlled by medical therapy. Due to the development of tertiary hyperparathyroidism with bone pain and osteoporosis, subtotal parathyroidectomy was performed 4 months after the kidney transplantation. Histological evaluation revealed that one of four parathyroid lesions was a parathyroid carcinoma, while the others were diffuse hyperplasia. Postoperative laboratory studies indicated a decreased level of iPTH. A positron emission tomography-computed tomography performed 6 months after the operation revealed no evidence of local recurrence or distant metastasis. Copyright © 2013.

  6. SU-E-J-103: Propagation of Rectum and Bladder Contours for Tandem and Ring (T&R) HDR Treatment Using Deformable Image Registration

    Energy Technology Data Exchange (ETDEWEB)

    Yuan, Y; Chao, M; Sheu, R; Dumane, V; Gupta, V; Lo, Y [Mount Sinai Medical Center, New York, NY (United States)


    Purpose: To investigate the feasibility of using DIR to propagate the manually contoured rectum and bladder from the 1st insertion to the new CT images on subsequent insertions and evaluate the segmentation performance. Methods: Ten cervical cancer patients, who were treated by T&R brachytherapy in 3–4 insertions, were retrospectively collected. In each insertion, rectum and bladder were manually delineated on the planning CT by a physicist and verified by a radiation oncologist. Using VelocityAI (Velocity Medical Solutions, Atlanta, GA), a rigid registration was firstly employed to match the bony structures between the first insertion and each of the following insertions, then a multi-pass B-spine DIR was carried out to further map the sub volume that encompasses rectum and bladder. The resultant deformation fields propagated contours, and dice similarity coefficient (DSC) was used to quantitatively evaluate the agreement between the propagated contours and the manually-delineated organs. For the 3rd insertion, we also evaluated if the segmentation performance could be improved by propagating the contours from the most recent insertion, i.e., the 2nd insertion. Results: On average, the contour propagation took about 1 minute. The average and standard deviation of DSC over all insertions and patients was 0.67±0.10 (range: 0.44–0.81) for rectum, and 0.78±0.07 (range: 0.63–0.87) for bladder. For the 3rd insertion, propagating contours from the 2nd insertion could improve the segmentation performance in terms of DSC from 0.63±0.10 to 0.72±0.08 for rectum, and from 0.77±0.07 to 0.79±0.06 for bladder. A Wilcoxon signed rank test indicated that the improvement was statistically significant for rectum (p = 0.004). Conclusion: The preliminary results demonstrate that deformable image registration could efficiently and accurately propagate rectum and bladder contours between CT images in different T&R brachytherapy fractions. We are incorporating the propagated

  7. Regionalised tertiary psychiatric residential facilities. (United States)

    Lesage, Alain; Groden, David; Goldner, Elliot M; Gelinas, Daniel; Arnold, Leslie M


    Psychiatric hospitals remain the main venue for long-term mental health care and, despite widespread closures and downsizing, no country that built asylums in the last century has done away with them entirely--with the recent exception of Italy. Differentiated community-based residential alternatives have been developed over the past decades, with staffing levels that range from full-time professional, to daytime only, to part-time/on-call. This paper reviews the characteristics of community-based psychiatric residential care facilities as an alternative to long-term care in psychiatric hospitals. It describes five factors decision makers should consider: 1. number of residential places needed; 2. staffing levels; 3. physical setting; 4. programming; and 5. governance and financing. In Italy, facilities with full-time professional staff have been developed since the mid-1990s to accommodate the last cohorts of patients discharged from psychiatric hospitals. In the United Kingdom, experiments with hostel wards since the 1980s have shown that home-like, small-scale facilities with intensive treatment and rehabilitation programming can be effective for the most difficult-to-place patients. More recently in Australia, Community Care Units (CCUs) have been applying this concept. In the Canadian province of British Columbia (BC), Tertiary Psychiatric Residential Facilities (TPRFs) have been developed as part of an effort to regionalise health and social services and downsize and ultimately close its only psychiatric hospital. This type of service must be further developed in addition to the need for forensic, acute-care and intermediate-level beds, as well as for community-based care such as assertive community treatment and intensive case management. All these types of services, together with long-term community-based residential care, constitute the elements of a balanced mental health care system. As part of a region's balanced mental health care plan, these Tertiary

  10. Radioguided parathyroidectomy for tertiary hyperparathyroidism. (United States)

    Somnay, Yash R; Weinlander, Eric; Alfhefdi, Amal; Schneider, David; Sippel, Rebecca S; Chen, Herbert


    Tertiary hyperparathyroidism (3HPT) is defined as the persistent hyperproduction of parathyroid hormone and resulting hypercalcemia after renal transplantation. Here, we examine the utility of radioguided parathyroidectomy (RGP) in patients with 3HPT. We reviewed a prospective surgery database containing 80 3HPT patients who underwent RGP from January 2001-July 2014 at our institution. We evaluated patient demographics, operative management, radioguided neoprobe utilization, and operative outcomes. Data are reported as mean ± standard error of the mean. The mean age of the patients was 52 ± 1 y, and 46% were male. A total of 69 patients had hyperplasia and received subtotal parathyroidectomy, whereas 5 patients had double adenomas and 6 patients had single adenomas. The average calcium level among 3HPT patients was 10.8 ± 0.1 mg/dL preoperatively and 8.7 ± 0.1 mg/dL postoperatively. In vivo radioguided counts normalized to background counts averaged 145 ± 4%, whereas ex vivo counts normalized to background counts averaged 69 ± 5%. All but one ex vivo count was >20%. Ectopically located glands were successfully localized in 38 patients using the gamma probe. Ex vivo percentage did not correlate with parathyroid gland weight, preoperative parathyroid hormone, or preoperative calcium. Our radioguided approach achieved normocalcemia in 96% of 3HPT patients undergoing RGP; two patients developed recurrent disease. In this series, all enlarged parathyroid glands were localized and resected using the gamma probe. Thus, RGP reliably localizes adenomatous, hyperplastic, and ectopically located glands in patients with 3HPT, resulting in high cure rate after resection. Copyright © 2015 Elsevier Inc.

    The exploitation of an oil field is a continously developing process, undergoing seveal stages, such as the low production, the high production, the stable production and the decline. The tertiary recovery is an important means of the enhanced oil recovery. Since the object of the tertiary recovery is to treat the oil in micropores which is difficult to be produced, it is more necessary to know further the reservoir. Tritide can be used as a tracer and is an ideal marker of knowing the reservoir and the state of the fluid movement. The paper presents the tritide injection equipment

    Woodring, W.P.


    Aside from its value as an aid in determining the age of Tertiary beds, the chief interest of the genus Clementia lies in the anomalous features of its present and former distribution. An attempt is made in this paper to trace its geologic history, to point out its paleobiologic significance, and to describe all the known American Tertiary species. The fossils from Colombia used in preparing this report were collected during explorations made under the direction of Dr. 0. B. Hopkins, chief geologist of the Imperial Oil Co. (Ltd.), who kindly donated them to the United States National Museum. Dr. T. Wayland Vaughan, of the Scripps Institution of Oceanography, furnished information relating to specimens collected by him in Mexico. Dr. Bruce L. Clark, of the University of California; Dr. G.

    Full Text Available The tertiary sector is one of the modern styles of economic systems in view of the share it occupies in the field of production as well as employment occupied share. Hence, just like other lands, the UAE, witnessed an economic structural change similar to developed and developing nations, where the tertiary industries contributed 55.4% in 2015 to total country’s income. The empirical study aimed to analyze the contribution portion of growth in the tertiary industries through using the growth accounting framework in time-series from 1990 to 2015. The empirical study found that most of the industries contributed significantly to the growth of the tertiary sector. The contribution shares of growth due to labor and capital varied among industries. The main observed results show that there was a vice versa relationship between TFP performance and the size of labor, where the TFP positively corresponded with the decline in the size of labor specifically from 2010-2015.

  2. Economics of Tertiary Education - Challenges and dynamics of the public tertiary education in Albania

    Directory of Open Access Journals (Sweden)

    Gledian Llatja


    Full Text Available The tertiary education is a critic mechanism for the socio-economic progress, for individuals who aspire a brighter future and it is also considered an important catalyzer of the economic mobility (Department of Treasury and Department of Education, 2012, 2. Based on the positive role and impact that the tertiary education has on the sustainable development, President Obama once stated that it is of damage to treat education as a luxurious public service. In line with the general considerations about the tertiary education in the U.S. the parallel comparison with Albania comes as a direct interpretation of utopia in the education policy-making. As policies are usually drafted based on data and findings, in the case of Albania there is a lack of data on expenses on tertiary education as share of GDP. This stands also for the main limitation of the paper.

  10. Transition radiation and transition scattering

    International Nuclear Information System (INIS)

    Ginzburg, V.L.


    Transition radiation is a process of a rather general character. It occurs when some source, which does not have a proper frequency (for example, a charge) moves at a constant velocity in an inhomogeneous and (or) nonstationary medium or near such a medium. The simplest type of transition radiation takes place when a charge crosses a boundary between two media (the role of one of the media may be played by vacuum). In the case of periodic variation of the medium, transition radiation possesses some specific features (resonance transition radiation or transition scattering). Transition scattering occurs, in particular, when a permittivity wave falls onto an nonmoving (fixed) charge. Transition scattering is closely connected with transition bremsstrahlung radiation. All these transition processes are essential for plasma physics. Transition radiation and transition scattering have analogues outside the framework of electrodynamics (like in the case of Vavilov-Cherenkov radiation). In the present report the corresponding range of phenomena is elucidated, as far as possible, in a generally physical aspect. (Auth.)

    Kobayashi, M.; Hosokawa, N.; Watanabe, T. [Tokyo Gas Fundamental Technology Research Lab. (Japan)


    Taking 'damage factor', 'ground response', 'soil pipe interaction', and 'deformability of pipes' as its four key concerns, Tokyo Gas F.T.R.L. is working to clarify the behavior of pipelines during strong earthquakes and improve their earthquake resistance to increase safety levels. In specific terms, Tokyo Gas F.T.R.L. has sought to contribute to earthquake resistance by, for example, conducting pipeline damage forecasts, FEM dynamic response analyses to quantify ground amplification, empirical and analytic studies of forces acting on pipelines, various vibration tests, and tests to determine the deforming behavior of pipes. A further important concern given the limited resources available is the prioritization of the pipes to be made more earthquake resistant. Ultimately, these studies should contribute to more rational and effective seismic design of pipelines and improvement of earthquake resistance both in the case of existing and new facilities and equipment.

  12. Stereoinversion of tertiary alcohols to tertiary-alkyl isonitriles and amines. (United States)

    Pronin, Sergey V; Reiher, Christopher A; Shenvi, Ryan A


    The SN2 reaction (bimolecular nucleophilic substitution) is a well-known chemical transformation that can be used to join two smaller molecules together into a larger molecule or to exchange one functional group for another. The SN2 reaction proceeds in a very predictable manner: substitution occurs with inversion of stereochemistry, resulting from the 'backside attack' of the electrophilic carbon by the nucleophile. A significant limitation of the SN2 reaction is its intolerance for tertiary carbon atoms: whereas primary and secondary alcohols are viable precursor substrates, tertiary alcohols and their derivatives usually either fail to react or produce stereochemical mixtures of products. Here we report the stereochemical inversion of chiral tertiary alcohols with a nitrogenous nucleophile facilitated by a Lewis-acid-catalysed solvolysis. The method is chemoselective against secondary and primary alcohols, thereby complementing the selectivity of the SN2 reaction. Furthermore, this method for carbon-nitrogen bond formation mimics a putative biosynthetic step in the synthesis of marine terpenoids and enables their preparation from the corresponding terrestrial terpenes. We expect that the general attributes of the methodology will allow chiral tertiary alcohols to be considered viable substrates for stereoinversion reactions.

  15. Thermodynamics and kinetics of RNA tertiary structure formation in the junctionless hairpin ribozyme. (United States)

    White, Neil A; Hoogstraten, Charles G


    The hairpin ribozyme consists of two RNA internal loops that interact to form the catalytically active structure. This docking transition is a rare example of intermolecular formation of RNA tertiary structure without coupling to helix annealing. We have used temperature-dependent surface plasmon resonance (SPR) to characterize the thermodynamics and kinetics of RNA tertiary structure formation for the junctionless form of the ribozyme, in which loops A and B reside on separate molecules. We find docking to be strongly enthalpy-driven and to be accompanied by substantial activation barriers for association and dissociation, consistent with the structural reorganization of both internal loops upon complex formation. Comparisons with the parallel analysis of a ribozyme variant carrying a 2'-O-methyl modification at the self-cleavage site and with published data in other systems reveal a surprising diversity of thermodynamic signatures, emphasizing the delicate balance of contributions to the free energy of formation of RNA tertiary structure.

  16. Phase transitions

    CERN Document Server

    Sole, Ricard V; Solé, Ricard V; Solé, Ricard V; Sol, Ricard V; Solé, Ricard V


    Phase transitions--changes between different states of organization in a complex system--have long helped to explain physics concepts, such as why water freezes into a solid or boils to become a gas. How might phase transitions shed light on important problems in biological and ecological complex systems? Exploring the origins and implications of sudden changes in nature and society, Phase Transitions examines different dynamical behaviors in a broad range of complex systems. Using a compelling set of examples, from gene networks and ant colonies to human language and the degradation of diverse ecosystems, the book illustrates the power of simple models to reveal how phase transitions occur. Introductory chapters provide the critical concepts and the simplest mathematical techniques required to study phase transitions. In a series of example-driven chapters, Ricard Solé shows how such concepts and techniques can be applied to the analysis and prediction of complex system behavior, including the origins of ...

    Huan ZHAO


    Full Text Available The second tertiary combined model experiment zone has been developed in Block B, Field L. The percolation feature of the second tertiary combined develop model shows great importance to rational and efficient development of the reservoir. In order to clearly illuminate its percolation feature, the typical reservoir numerical model is built by Eclipse, which is a reservoir numerical simulation software. The percolation features of original and added perforation interval under the second tertiary combined model are studied, and the variation features of general water-cut, recovery percentage, wellbore pressure, reservoir pressure and water saturation on condition of higher injection rate under the second tertiary combined model are analyzed. The research indicates that the second tertiary combined enhances the recovery of remaining oil on top of thick reservoir by developing and enhancing original perforation interval under water drive, then improves development results by polymer flooding, and gains higher recovery rate by synthetic action of water driver and polymer flooding.

  8. Tertiary lymphoid structures in cancer and beyond. (United States)

    Dieu-Nosjean, Marie-Caroline; Goc, Jérémy; Giraldo, Nicolas A; Sautès-Fridman, Catherine; Fridman, Wolf Herman


    Tertiary lymphoid structures (TLS) are ectopic lymphoid formations found in inflamed, infected, or tumoral tissues. They exhibit all the characteristics of structures in the lymph nodes (LN) associated with the generation of an adaptive immune response, including a T cell zone with mature dendritic cells (DC), a germinal center with follicular dendritic cells (FDC) and proliferating B cells, and high endothelial venules (HEV). In this review, we discuss evidence for the roles of TLS in chronic infection, autoimmunity, and cancer, and address the question of whether TLS present beneficial or deleterious effects in these contexts. We examine the relationship between TLS in tumors and patient prognosis, and discuss the potential role of TLS in building and/or maintaining local immune responses and how this understanding may guide therapeutic interventions.

    To evaluate whether a 3 D proton density-weighted fat-suppressed sequence (PDwFS) of the knee is able to replace multiplanar 2D-PDwFS. 52 patients (26 men, mean age: 41.9 ± 14.5years) underwent magnetic resonance imaging (MRI) of the knee at 3.0 Tesla using a T/R-coil. The imaging protocol included 3 planes of 2D-PDwFS (acquisition time (AT): 6:40 min; voxel sizes: 0.40 - 0.63 × 0.44 - 0.89 × 3mm³) and a 3D-PDwFS (AT: 6:31 min; voxel size: 0.63 × 0.68 × 0.63mm³). Homogeneity of fat suppression (HFS), artifacts, and image sharpness (IS) were evaluated on a 5-point scale (5[excellent] - 1[non-diagnostic]). The sum served as a measure for the overall image quality (OIQ). Contrast ratios (CR) compared to popliteal muscle were calculated for the meniscus (MEN), anterior (ACL) and posterior cruciate ligaments (PCL). In 13 patients who underwent arthroscopic knee surgery, two radiologists evaluated the presence of meniscal, ligamental and cartilage lesions to estimate the sensitivity and specificity of lesion detection. The CR was higher in the ACL, PCL and MEN in 3D- PDwFS compared to 2D-PDwFS (p Tesla Using a T/R-Coil Can Replace Multiple Plane Two-Dimensional Sequences in Knee Imaging.

  11. A General Catalyst for Site-Selective C(sp(3))-H Bond Amination of Activated Secondary over Tertiary Alkyl C(sp(3))-H Bonds. (United States)

    Scamp, Ryan J; Jirak, James G; Dolan, Nicholas S; Guzei, Ilia A; Schomaker, Jennifer M


    The discovery of transition metal complexes capable of promoting general, catalyst-controlled and selective carbon-hydrogen (C-H) bond amination of activated secondary C-H bonds over tertiary alkyl C(sp(3))-H bonds is challenging, as substrate control often dominates when reactive nitrene intermediates are involved. In this letter, we report the design of a new silver complex, [(Py5Me2)AgOTf]2, that displays general and good-to-excellent selectivity for nitrene insertion into propargylic, benzylic, and allylic C-H bonds over tertiary alkyl C(sp(3))-H bonds.

  12. Remote Sensing Tertiary Education Meets High Intensity Interval Training (United States)

    Joyce, K. E.; White, B.


    Enduring a traditional lecture is the tertiary education equivalent of a long, slow, jog. There are certainly some educational benefits if the student is able to maintain concentration, but they are just as likely to get caught napping and fall off the back end of the treadmill. Alternatively, a pre-choreographed interactive workshop style class requires students to continually engage with the materials. Appropriately timed breaks or intervals allow students to recover briefly before being increasingly challenged throughout the class. Using an introductory remote sensing class at Charles Darwin University, this case study presents a transition from the traditional stand and deliver style lecture to an active student-led learning experience. The class is taught at undergraduate and postgraduate levels, with both on-campus as well as online distance learning students. Based on the concept that active engagement in learning materials promotes 'stickiness' of subject matter, the remote sensing class was re-designed to encourage an active style of learning. Critically, class content was reviewed to identify the key learning outcomes for the students. This resulted in a necessary sacrifice of topic range for depth of understanding. Graduates of the class reported high levels of enthusiasm for the materials, and the style in which the class was taught. This paper details a number of techniques that were used to engage students in active and problem based learning throughout the semester. It suggests a number of freely available tools that academics in remote sensing and related fields can readily incorporate into their teaching portfolios. Moreover, it shows how simple it can be to provide a far more enjoyable and effective learning experience for students than the one dimensional lecture.

    Full Text Available BACKGROUND Hyponatraemia is defined as a serum sodium level less than 135 mEq/L. High mortality among the patients of hyponatraemia is secondary to the underlying medical condition. Frequency is high in elderly patients. MATERIALS AND METHODS The study was conducted at a tertiary care centre (Basaveshwar Teaching and General Hospital, Gulbarga, from the period September 2014 to August 2016. These patients were evaluated for the underlying cause of hyponatraemia, which included detailed history and physical examination followed by appropriate laboratory investigations. Patients were followed up till the hyponatraemia was treated or patients were discharged from the hospital. RESULTS 100 patients of hyponatraemia were included in the study. 46% of the patients were asymptomatic. 33% patients had lethargy, 28% patients had postural dizziness and 19% had abnormal behaviour. Overall incidence of hyponatraemia was 4.58% in the hospitalised population, whereas its incidence in ICU patients was 22.4%. Twelve patients of symptomatic severe hyponatraemia were treated with hypertonic saline infusion, 25% patients were given loop diuretics with oral supplementation of sodium chloride for free water excretion in SIADH cases and in patients with hypervolaemia, hyponatraemia, fluid restriction was advised to 44 patients, oral supplementation of sodium chloride was given in 36 patients and 64 patients received normal saline. 9 patients included in the study died, 5 of which had advanced cirrhosis of liver as underlying cause. One patient developed Osmotic Demyelination Syndrome (ODS. CONCLUSION The possible cause of hyponatraemia should always be sought as outcome in severe hyponatraemia is governed by aetiology, and not by the serum sodium level. Treatment of severe symptomatic hyponatraemia with hypertonic saline is safe if recommendation for the rate of correction of hyponatraemia is strictly followed.

The presence of B cell aggregates (CD20, follicular dendritic cells (FDCs, CD21, and high endothelial venules (HEVs, PNAd was investigated by immunohistochemistry. Immune cells from the adventitial layer of one patient were characterized by flow cytometry. Demographic, medical history, laboratory, imaging, treatment and follow up data were extracted from medical records.Results: Aorta specimens from Bentall procedures were available from 7 patients (five female, aged 22 to 57 years with TA. Surgical treatment was performed at TA diagnosis (n=4 or at a median of 108 months [84-156] after TA diagnosis. Disease was active at surgery in four patients according to NIH score. B cell aggregates-TLOs containing HEVs were observed in the adventitia of all but one patient.. Of note, ectopic follicles containing CD21+ FDCs were found in all patients (4/4 with increased aortic FDG uptake before surgery but were absent in all but one patients (2/3 with no FDG uptake. In addition, flow cytometry analysis confirmed the accumulation of memory/germinal center–like B cells in the adventitial layer and showed the presence of antigen-experienced T follicular helper cells.Conclusion: Ectopic lymphoid neogenesis displaying functional features can be found in the aortic wall of a subset of patients with active TA. The function of these local B cell clusters on the pathogenesis of TA remains to be elucidated.

    We investigate amide nonplanarity in vibrational optical activity (VOA) spectra of tricyclic spirodilactams 5,8-diazatricyclo[6,3,0,0(1,5)]undecan-4,9-dione (I) and its 6,6',7,7'-tetradeuterio derivative (II). These rigid molecules constrain amide groups to nonplanar geometries with twisted pyramidal arrangements of bonds to amide nitrogen atoms. We have collected a full range vibrational circular dichroism (VCD) and Raman optical activity (ROA) spectra including signals of C-H and C-D stretching vibrations. We report normal-mode analysis and a comparison of calculated to experimental VCD and ROA. The data provide band-to-band assignment and offer a possibility to evaluate roles of constrained nonplanar tertiary amide groups and rigid chiral skeletons. Nonplanarity shows as single-signed VCD and ROA amide I signals, prevailing the couplets expected to arise from the amide-amide interaction. Amide-amide coupling dominates amide II (mainly C'-N stretching, modified in tertiary amides by the absence of a N-H bond) transitions (strong couplet in VCD, no significant ROA) probably due to the close proximity of amide nitrogen atoms.

    Homans, S W; Dwek, R A; Rademacher, T W


    Distance constraints derived from two-dimensional nuclear Overhauser effect measurements have been used to define the orientation of the Man alpha 1-3Man beta linkage in seven different N-linked oligosaccharides, all containing the common pentasaccharide core Man alpha 1-6(Man alpha 1-3)Man beta 1-4GlcNAc beta 1-4GlcNAc. Conformational invariance of the Man alpha 1-3Man beta linkage was found for those structures bearing substitutions on the Man alpha 1-3Man beta antenna. However, the presence of either a GlcNAc residue in the beta 1-4 linkage to Man beta ("bisecting GlcNAc") or a xylose residue in the beta 1-2 linkage to Man beta of the trimannosyl core was found to generate conformational transitions that were similar. These transitions were accompanied by characteristic chemical shift perturbations of proton resonances in the vicinity of the Man alpha 1-3Man beta linkage. Molecular orbital energy calculations suggest that the conformational transition between the unsubstituted and substituted cores arises from energetic constraints in the vicinity of the Man alpha 1-3Man beta linkage, rather than specific long-range interactions. These data taken together with our previous results on the Man alpha 1-6Man beta linkage [Homans, S. W., Dwek R. A., Boyd, J., Mahmoudian, M., Richards, W. G., & Rademacher, T. W. (1986) Biochemistry 25, 6342] allow us to discuss the consequences of the modulation of oligosaccharide solution conformations.

  16. Planktonic benthonic foraminiferal ratios: Modern patterns and Tertiary applicability (United States)

    Gibson, T.G.


    The abundance of planktonic specimens in foraminiferal assemblages was determined in numerous bottom samples from inner neritic to deep oceanic depths along the Atlantic margin of the northeastern United States. The results augment previous studies in other areas that have shown a general increase in percentage of planktonic specimens in total foraminiferal bottom assemblages as water depth increases. The patterns found in this area of complex shelf bathymetry and hydrography illustrate the influence on the planktonic-benthonic percentages of water depth, distance from shore, different water mass properties and downslope movement of tests in high energy areas. The patterns found in the 661 samples from the Atlantic margin were compared with results from 795 stations in the Gulf of Mexico, Pacific Ocean and Red Sea. The relative abundance of planktonic specimens and water depth correlates positively in all open oceanic areas even though taxonomic composition and diversity of the faunas from different areas is variable. The variation of planktonic percentages in bottom samples within most depth intervals is large so that a precise depth determination cannot be made for any given value. However, an approximate upper depth limit for given percentages can be estimated for open ocean environments. A decrease in planktonic percentages is seen in the lower salinity and higher turbidity coastal waters of the Gulf of Maine. Planktonic percentages intermediate between the lower values in the less saline coastal waters and the higher values in the normal open oceanic conditions occur in the transitional area between the Gulf of Maine and the open marine Atlantic Ocean to the east. Similarly lowered values in another area of restricted oceanic circulation occur in the high salinity, clear, but nutrient-poor waters of the Gulf of Aqaba off the Red Sea. A comparison of the similarity of modern planktonic percentage values to those found in earlier Tertiary assemblages was made to

  17. Current demand of paediatric otolaryngology input for children with Down's syndrome in a tertiary referral centre. (United States)

    Khalid-Raja, M; Tzifa, K


    This study aimed to evaluate the activity of paediatric otolaryngology services required for children with Down's syndrome in a tertiary referral centre. A review of the paediatric otolaryngology input for children with Down's syndrome was performed; data were obtained from the coding department for a two-year period and compared with other surgical specialties. Between June 2011 and May 2013, 106 otolaryngology procedures were performed on children with Down's syndrome. This compared to 87 cardiac and 81 general paediatrics cases. The most common pathologies in children with Down's syndrome were obstructive sleep apnoea, otitis media, hearing loss and cardiac disease. The most common otolaryngology procedures performed were adenoidectomy, tonsillectomy, grommet insertion and bone-anchored hearing aid implant surgery. ENT manifestations of Down's syndrome are common. Greater provisions need to be made to streamline the otolaryngology services for children and improve transition of care to adult services.

  18. Transitional issues

    International Nuclear Information System (INIS)


    This discussion paper, the fifth in the series developed at the IPPSO Market Design Conference, addressed the issue of the need to prevent Ontario Hydro from taking unfair advantage of independent producers and other stakeholders through activities and investments in new power generating capacity in the transitional period leading up to deregulation. The need for controls is predicated on the assumption that the short-term actions and investments of Ontario Hydro could seriously compromise the position of independent generators, and that without such controls the level playing field essential to the operation of a competitive market, does not exist. Various actual and potential actions of Ontario Hydro were discussed, all of which point to the need for strict controls over Ontario Hydro exercising its dominant market power in an unfair way. It was recommended that as a minimum, the provincial government should no longer provide guarantees for Ontario Hydro capital projects, and that Ontario Hydro be instructed to defer any investment on new or returning generating capacity until the new market is in place. Limits could also be placed on Ontario Hydro's marketing efforts to enter into contracts during the transition period, and Ontario Hydro and municipal utilities should be required to keep separate accounts of their commercial preparation, and to settle such accounts separate from ratepayer revenue

  19. The equity imperative in tertiary education: Promoting fairness and efficiency (United States)

    Salmi, Jamil; Bassett, Roberta Malee


    While the share of the tertiary education age cohort (19-25) which is being given the opportunity to study has increased worldwide over the past two decades, this does not in fact translate into reduced inequality. For many young people, especially in the developing world, major obstacles such as disparities in terms of gender, minority population membership or disabilities as well as academic and financial barriers are still standing in their way. The authors of this article propose a conceptual framework to analyse equity issues in tertiary education and document the scope, significance and consequences of disparities in tertiary education opportunities. They throw some light on the main determinants of these inequalities and offer suggestions about effective equity promotion policies directed towards widening participation and improving the chances of success of underprivileged youths in order to create societies which uphold humanistic values.

  20. The MSSM Electroweak Phase Transition on the Lattice

    CERN Document Server

    Laine, Mikko


    We study the MSSM finite temperature electroweak phase transition with lattice Monte Carlo simulations, for a large Higgs mass (m_H ~ 95 GeV) and light stop masses (m_tR ~ 150...160 GeV). We employ a 3d effective field theory approach, where the degrees of freedom appearing in the action are the SU(2) and SU(3) gauge fields, the weakly interacting Higgs doublet, and the strongly interacting stop triplet. We determine the phase diagram, the critical temperatures, the scalar field expectation values, the latent heat, the interface tension and the correlation lengths at the phase transition points. Extrapolating the results to the infinite volume and continuum limits, we find that the transition is stronger than indicated by 2-loop perturbation theory, guaranteeing that the MSSM phase transition is strong enough for baryogenesis in this regime. We also study the possibility of a two-stage phase transition, in which the stop field gets an expectation value in an intermediate phase. We find that a two-stage transi...

  1. Energy transition

    International Nuclear Information System (INIS)



    The yearly environmental conference will hold on September 2013 to evaluate the negotiations led at the national and local levels for december 2012. The government will have then to decide of an energy programming bill which will be submitted to the Parliament at the beginning of the year 2014. 30 main propositions have emerged of the decentralised debates. One of them is the ecological taxation which raise the question of the gas oil and petrol taxation. The current environmental taxes are for almost three quarters of them taxes on energy consumptions and mainly on fossil energies. The Economic, Social and Environmental Council, gives his opinion on the way to find resources to ensure the ecological and energy transition while reducing the public deficit of the State. (O.M.)

  2. Spatio-temporal observations of the tertiary ozone maximum

    Directory of Open Access Journals (Sweden)

    V. F. Sofieva


    Full Text Available We present spatio-temporal distributions of the tertiary ozone maximum (TOM, based on GOMOS (Global Ozone Monitoring by Occultation of Stars ozone measurements in 2002–2006. The tertiary ozone maximum is typically observed in the high-latitude winter mesosphere at an altitude of ~72 km. Although the explanation for this phenomenon has been found recently – low concentrations of odd-hydrogen cause the subsequent decrease in odd-oxygen losses – models have had significant deviations from existing observations until recently. Good coverage of polar night regions by GOMOS data has allowed for the first time to obtain spatial and temporal observational distributions of night-time ozone mixing ratio in the mesosphere.

    The distributions obtained from GOMOS data have specific features, which are variable from year to year. In particular, due to a long lifetime of ozone in polar night conditions, the downward transport of polar air by the meridional circulation is clearly observed in the tertiary ozone maximum time series. Although the maximum tertiary ozone mixing ratio is achieved close to the polar night terminator (as predicted by the theory, TOM can be observed also at very high latitudes, not only in the beginning and at the end, but also in the middle of winter. We have compared the observational spatio-temporal distributions of the tertiary ozone maximum with that obtained using WACCM (Whole Atmosphere Community Climate Model and found that the specific features are reproduced satisfactorily by the model.

    Since ozone in the mesosphere is very sensitive to HOx concentrations, energetic particle precipitation can significantly modify the shape of the ozone profiles. In particular, GOMOS observations have shown that the tertiary ozone maximum was temporarily destroyed during the January 2005 and December 2006 solar proton events as a result of the HOx enhancement from the increased ionization.

  3. Discovery of tertiary sulfonamides as potent liver X receptor antagonists. (United States)

    Zuercher, William J; Buckholz, Richard G; Campobasso, Nino; Collins, Jon L; Galardi, Cristin M; Gampe, Robert T; Hyatt, Stephen M; Merrihew, Susan L; Moore, John T; Oplinger, Jeffrey A; Reid, Paul R; Spearing, Paul K; Stanley, Thomas B; Stewart, Eugene L; Willson, Timothy M


    Tertiary sulfonamides were identified in a HTS as dual liver X receptor (LXR, NR1H2, and NR1H3) ligands, and the binding affinity of the series was increased through iterative analogue synthesis. A ligand-bound cocrystal structure was determined which elucidated key interactions for high binding affinity. Further characterization of the tertiary sulfonamide series led to the identification of high affinity LXR antagonists. GSK2033 (17) is the first potent cell-active LXR antagonist described to date. 17 may be a useful chemical probe to explore the cell biology of this orphan nuclear receptor.

  5. Sexual harassment in tertiary institutions: A comparative perspective

    Directory of Open Access Journals (Sweden)

    Joseph Janice


    Full Text Available Sexual harassment is not a new phenomenon in tertiary institutions. It has been receiving considerable attention in research and the media and public awareness has increased dramatically. However, the term sexual harassment is not used uniformly across the globe because countries have defined it differently. Consequently, prevalence of sexual harassment in education varies across cultures. This paper examines sexual harassment from a comparative perspective. It specifically focuses on the definition of sexual harassment, incidence of sexual harassment of students in tertiary institutions, effects of sexual harassment on victims; and victims’ responses to sexual harassment. It also offers suggestions for curtailing sexual harassment in these institutions.

  6. Design and development of a surface micro-machined push–pull-type true-time-delay phase shifter on an alumina substrate for Ka-band T/R module application

    International Nuclear Information System (INIS)

    Dey, Sukomal; Koul, Shiban K


    A radio frequency micro-electro-mechanical system (RF-MEMS) phase shifter based on the distributed MEMS transmission line (DMTL) concept towards maximum achievable phase shift with low actuation voltage with good figure of merit (FOM) is presented in this paper. This surface micro-machined analog DMTL phase shifter demonstrates low power consumption for implementation in a Ka-band transmit/receive (T/R) module. The push–pull-type switch has been designed and optimized with an analytical method and validated with simulation, which is the fundamental building block of the design of a true-time-delay phase shifter. Change in phase has been designed and optimized in push and pull states with reference to the up-state performance of the phase shifter. The working principle of this push–pull-type DMTL phase shifter has been comprehensively worked out. A thorough detail of the design and performance analysis of the phase shifter has been carried out with various structural parameters using commercially available simulation tools with reference to a change in phase shift and has been verified using a system level simulation. The phase shifter is fabricated on the alumina substrate, using a suspended gold bridge membrane with a surface micromachining process. Asymmetric behaviour of push–pull bridge configuration has been noted and a corresponding effect on mechanical, electrical and RF performances has been extensively investigated. It is demonstrated 114° dB −1 FOM over 0–40 GHz band, which is the highest achievable FOM from a unit cell on an alumina substrate reported so far. A complete phase shifter contributes to a continuous differential phase shift of 0°–360° over 0–40 GHz band with a minimum actuation voltage of 8.1 V which is the highest achievable phase shift with the lowest actuation voltage as per till date on the alumina substrate with good repeatability and return loss better than 11.5 dB over 0–40 GHz band.

  7. Three-dimensional isotropic fat-suppressed proton density-weighted MRI at 3 tesla using a T/R-coil can replace multiple plane two-dimensional sequences in knee imaging

    Energy Technology Data Exchange (ETDEWEB)

    Homsi, R.; Luetkens, J.A. [Bonn Univ. (Germany). Dept. of Radiology; Gieseke, J. [Philips Healthcare, Hamburg (Germany); and others


    To evaluate whether a 3D proton density-weighted fat-suppressed sequence (PDwFS) of the knee is able to replace multiplanar 2D-PDwFS. 52 patients (26 men, mean age: 41.9±14.5 years) underwent magnetic resonance imaging (MRI) of the knee at 3.0 Tesla using a T/R-coil. The imaging protocol included 3 planes of 2D-PDwFS (acquisition time (AT): 6:40 min; voxel sizes: 0.40-0.63 x 0.44-0.89 x 3 mm{sup 3}) and a 3D-PDwFS (AT: 6:31 min; voxel size: 0.63 x 0.68 x 0.63 mm{sup 3}). Homogeneity of fat suppression (HFS), artifacts, and image sharpness (IS) were evaluated on a 5-point scale (5[excellent] - 1[non-diagnostic]). The sum served as a measure for the overall image quality (OIQ). Contrast ratios (CR) compared to popliteal muscle were calculated for the meniscus (MEN), anterior (ACL) and posterior cruciate ligaments (PCL). In 13 patients who underwent arthroscopic knee surgery, two radiologists evaluated the presence of meniscal, ligamental and cartilage lesions to estimate the sensitivity and specificity of lesion detection. The CR was higher in the ACL, PCL and MEN in 3D- PDwFS compared to 2D-PDwFS (p<0.01 for ACL and PCL; p=0.07 for MEN). Compared to 2D images, the OIQ was rated higher in 3D-PDwFS images (p<0.01) due to fewer artifacts and HFS despite the lower IS (p<0.01). The sensitivity and specificity of lesion detection in 3D- and 2D-PDwFS were similar. Compared to standard multiplanar 2D-PDwFS knee imaging, isotropic high spatial resolution 3D-PDwFS of the knee at 3.0T can be acquired with high image quality in a reasonable scan time. Multiplanar reformations in arbitrary planes may serve as an additional benefit of 3D-PDwFS.

  2. Epilepsy in Ireland: towards the primary-tertiary care continuum. (United States)

    Varley, Jarlath; Delanty, Norman; Normand, Charles; Coyne, Imelda; McQuaid, Louise; Collins, Claire; Boland, Michael; Grimson, Jane; Fitzsimons, Mary


    Epilepsy is a chronic neurological disease affecting people of every age, gender, race and socio-economic background. The diagnosis and optimal management relies on contribution from a number of healthcare disciplines in a variety of healthcare settings. To explore the interface between primary care and specialist epilepsy services in Ireland. Using appreciative inquiry, focus groups were held with healthcare professionals (n=33) from both primary and tertiary epilepsy specialist services in Ireland. There are significant challenges to delivering a consistent high standard of epilepsy care in Ireland. The barriers that were identified are: the stigma of epilepsy, unequal access to care services, insufficient human resources, unclear communication between primary-tertiary services and lack of knowledge. Improving the management of people with epilepsy requires reconfiguration of the primary-tertiary interface and establishing clearly defined roles and formalised clinical pathways. Such initiatives require resources in the form of further education and training and increased usage of information communication technology (ICT). Epilepsy services across the primary-tertiary interface can be significantly enhanced through the implementation of a shared model of care underpinned by an electronic patient record (EPR) system and information communication technology (ICT). Better chronic disease management has the potential to halt the progression of epilepsy with ensuing benefits for patients and the healthcare system. Copyright 2009 British Epilepsy Association.

  19. Tertiary syphilis in the lumbar spine: a case report. (United States)

    Bai, Yang; Niu, Feng; Liu, Lidi; Sha, Hui; Wang, Yimei; Zhao, Song


    The incidence of tertiary syphilis involvement in the spinal column with destructive bone lesions is very rare. It is difficult to establish the correct diagnosis from radiographs and histological examination alone. Limited data are available on surgical treatment to tertiary syphilitic spinal lesions. In this article, we report a case of tertiary syphilis in the lumbar spine with osteolytic lesions causing cauda equina compression. A 44-year-old man who suffered with low back pain for 6 months and progressive radiating pain at lower extremity for 1 week. Radiologic findings showed osteolytic lesion and new bone formation in the parts of the bodies of L4 and L5. Serum treponema pallidum hemagglutination (TPHA) test was positive. A surgery of posterior debridement, interbody and posterolateral allograft bone fusion with instrumentation from L3 to S1 was performed. The low back pain and numbness abated after operation. But the follow-up radiographs showed absorption of the bone grafts and failure of instrumentation. A Charcot's arthropathy was formed between L4 and L5. It is challenging to diagnose the tertiary syphilis in the spine. Surgery is a reasonable auxiliary method to antibiotic therapy for patients who suffered with neuropathy. Charcot's arthropathy should be considered as an operative complication.

  6. Favorability for uranium in tertiary sedimentary rocks, southwestern Montana

    International Nuclear Information System (INIS)

    Wopat, M.A.; Curry, W.E.; Robins, J.W.; Marjaniemi, D.K.


    Tertiary sedimentary rocks in the basins of southwestern Montana were studied to determine their favorability for potential uranium resources. Uranium in the Tertiary sedimentary rocks was probably derived from the Boulder batholith and from silicic volcanic material. The batholith contains numerous uranium occurrences and is the most favorable plutonic source for uranium in the study area. Subjective favorability categories of good, moderate, and poor, based on the number and type of favorable criteria present, were used to classify the rock sequences studied. Rocks judged to have good favorability for uranium deposits are (1) Eocene and Oligocene strata and undifferentiated Tertiary rocks in the western Three Forks basin and (2) Oligocene rocks in the Helena basin. Rocks having moderate favorability consist of (1) Eocene and Oligocene strata in the Jefferson River, Beaverhead River, and lower Ruby River basins, (2) Oligocene rocks in the Townsend and Clarkston basins, (3) Miocene and Pliocene rocks in the Upper Ruby River basin, and (4) all Tertiary sedimentary formations in the eastern Three Forks basin, and in the Grasshopper Creek, Horse Prairie, Medicine Lodge Creek, Big Sheep Creek, Deer Lodge, Big Hole River, and Bull Creek basins. The following have poor favorability: (1) the Beaverhead Conglomerate in the Red Rock and Centennial basins, (2) Eocene and Oligocene rocks in the Upper Ruby River basin, (3) Miocene and Pliocene rocks in the Townsend, Clarkston, Smith River, and Divide Creek basins, (4) Miocene through Pleistocene rocks in the Jefferson River, Beaverhead River, and Lower Ruby River basins, and (5) all Tertiary sedimentary rocks in the Boulder River, Sage Creek, Muddy Creek, Madison River, Flint Creek, Gold Creek, and Bitterroot basins

  8. Prospective analysis of percutaneous endoscopic colostomy at a tertiary referral centre. (United States)

    Baraza, W; Brown, S; McAlindon, M; Hurlstone, P


    Percutaneous endoscopic colostomy (PEC) is an alternative to surgery in selected patients with recurrent sigmoid volvulus, recurrent pseudo-obstruction or severe slow-transit constipation. A percutaneous tube acts as an irrigation or decompressant channel, or as a mode of sigmoidopexy. This prospective study evaluated the safety and efficacy of this procedure at a single tertiary referral centre. Nineteen patients with recurrent sigmoid volvulus, ten with idiopathic slow-transit constipation and four with pseudo-obstruction underwent PEC. The tube was left in place indefinitely in those with recurrent sigmoid volvulus or constipation, whereas in patients with pseudo-obstruction it was left in place for a variable period of time, depending on symptoms. Thirty-five procedures were performed in 33 patients. Three patients developed peritonitis, of whom one died, and ten patients had minor complications. Symptoms resolved in 26 patients. This large prospective study has confirmed the value of PEC in the treatment of recurrent sigmoid volvulus and pseudo-obstruction in high-risk surgical patients.

  9. Yb(OTf){sub 3}-catalyzed one-pot three component synthesis for tertiary amines

    Energy Technology Data Exchange (ETDEWEB)

    Lee, Bum Seok; Kim, Ji Hye; Nam, Tae Kyu; Jang, Doo Ok [Dept. of Chemistry, Yonsei University, Wonju (Korea, Republic of)


    Tertiary amine functionality is found in many natural bioactive products such as alkaloids, amino acids, nucleic acids, pharmaceuticals, and agrochemicals. Tertiary amines have also been used as building blocks for nitrogen-containing organic compounds and synthetic polymers. A one-pot method for direct reductive amination of aldehydes has been developed to synthesize tertiary amines using HMDS as a nitrogen source in the presence of Yb(OTf ){sub 3}. With a stoichiometric amount of HMDS, the reaction afforded the desired tertiary amines without competitive reduction of the parent carbonyl compounds. This reaction offers a convenient and efficient protocol for synthesizing aromatic and aliphatic tertiary amines under mild reaction conditions.

  11. Medical treatment of primary, secondary, and tertiary hyperparathyroidism. (United States)

    Vestergaard, Peter; Thomsen, Susanna vid Strym


    Hyperparathyroidism is a condition with elevated parathyroid hormone (PTH). The increase may be due to a) primary hyperparathyroidism which is caused by adenoma of one or more parathyroid glands or hyperplasia of all four glands, b) secondary hyperparathyroidism, which may be caused by deficiency in vitamin D or uremia, and 3) tertiary hyperparathyroidism, which most often is the result of a long-standing, severe secondary hyperparathyroidism, which has turned autonomous once the cause of the secondary hyperparathyroidism has been removed. Many new treatment options have been introduced in recent years. Cinacalcet is calcium sensing receptor agonist, which by stimulating the receptor decreases PTH and calcium levels. It may be used in primary hyperparathyroidism, secondary hyperparathyroidism caused by uremia, which may not be controlled with calcium and activated vitamin D. It may also be used in tertiary hyperparathyroidism. Newer analogues of vitamin D such as paricalcitol have also been introduced, which may have an advantage over traditional compounds such as alphacalcidol and calcitriol.

    The public perception of nuclear science and engineering and the nuclear industry is today, primarily shaped by radical greens, nuclear-opponents, the media and socio-political opportunists. Only countries with a well diversified tertiary education system embracing all aspects of nuclear science and engineering can counter efficiently the pseudo-science and socio-political manipulation which has severely restricted nuclear energy development over the past three decades. National laboratories alone find this task extremely difficult, if not impossible

  17. Glycerol tertiary butyl ethers via etherification of glycerol with isobutene

    Behr, A. [Dortmund Univ. (Germany). Chair of Chemical Process Development/Technical Chemistry A


    Glycerol and isobutene can react to a mixture of glycerol tertiary butyl ethers (GTBE) which can be used as additives for gasoline, diesel or biodiesel. This reaction was investigated in lab scale yielding a proposal for a process flow diagram containing reaction, extraction, flash and rectification units. This process has the advantages that only the suitable higher ethers are formed and that both glycerol and isobutene are fully converted. The homogeneous acid catalyst is low-priced and can be completely recycled. (orig.)

    Ectopic (or tertiary) lymphoid tissue develops at sites of inflammation or infection in non lymphoid organs and is associated with chronic inflammation. In colon mucosa, small lymphoid aggregates are already present in homeostatic conditions, as part of the gut-associated lymphoid tissue and play an essential role in the immune response to perturbations of the mucosal microenvironment. Despite the recognized role of inflammation in tumor progression, the presence and biological function of ly...

  19. Increased oil recovery: secondary and tertiary. Application and future prospect

    Energy Technology Data Exchange (ETDEWEB)

    Whiting, R L


    Oil is initially produced using the nature reservoir pressure present, in a process called primary oil recovery. Secondary recovery uses artificial means to increase the natural reservoir pressure; tertiary, or enhanced oil recovery, uses a number of methods to enhance the flow characteristics of the oil. The scope for such techniques to increase the yield from oil fields in the US is estimated; the practicality of their application is shown to be particularly dependent upon pricing, taxation, and other existing policies. 16 references.

    Heimark, Sondre; Eskås, Per Anders; Mariampillai, Julian Eek; Larstorp, Anne Cecilie K; Høieggen, Aud; Fadl Elmula, Fadl Elmula M


    Treatment-resistant hypertension (TRH) has regained attention with development of new methods for treatment. However, the prevalence of TRH varies considerably from primary to secondary and tertiary care. We aimed to assess the prevalence of true TRH in a population of patients with apparent TRH in a university hospital setting of tertiary work-up and also investigate reasons for poor BP control and evaluate how work-up can be performed in general practice and secondary care. In this cohort study, we characterize a study population from Oslo Renal Denervation (RDN) Study. Patients (n = 83) were referred for RDN from secondary care. All patients underwent thorough medical investigation and 24-h ambulatory blood pressure measurements (24ABPM) after directly observed therapy (DOT). We then assessed reasons for lack of BP control. Fifty-three of 83 patients did not have true TRH. Main reasons for non-TRH were poor drug adherence (32%), secondary hypertension (30%) and white coat hypertension (15%). Forty-seven percent achieved blood pressure control after DOT with subsequent 24ABPM. There were otherwise no statistically significant differences in patient characteristics between the true TRH and the non-TRH group. Despite being a highly selected cohort referred for tertiary work-up of apparent TRH, BP control was achieved or secondary causes were identified in almost two thirds of the patients. Thorough investigation according to guidelines and DOT with subsequent 24ABPM is needed in work-up of apparent TRH.

  2. Tertiary Education and the Crisis of Public Finance

    Directory of Open Access Journals (Sweden)

    Milos Maryska


    Full Text Available Turbulent economic environment after overwhelming the last crisis period is typical for present days as well as permanent increasing dependability of all our activities on information and communication technology (ICT. Although the global economic crisis was the reason for disinvestment into ICT in 2009 there is expected that ICT will generate almost 5.8 million new jobs in Europe till year 2013 and they have to be saturated also by adequately qualified ICT specialists.This contribution presents the research in the progress focused on the tertiary education system in the Czech Republic. We are predicting trends in education and especially in ICT education in Europe and in the Czech Republic as well for next ten years. We can expect that future ten years period will be critical not only for the Czech tertiary education system, but also for the Czech Republic because number of ICT students will be decreasing and number of ICT specialist demanded by labor market will be increasing. From macroeconomic point of view we can expect that also state subventions into state governed tertiary education system will decrease in the whole Europe.Some recommendations, proposals and forecasts for further development of education system are presented at the end of this contribution.

  3. General Allylic C–H Alkylation with Tertiary Nucleophiles (United States)


    A general method for intermolecular allylic C–H alkylation of terminal olefins with tertiary nucleophiles has been accomplished employing palladium(II)/bis(sulfoxide) catalysis. Allylic C–H alkylation furnishes products in good yields (avg. 64%) with excellent regio- and stereoselectivity (>20:1 linear:branched, >20:1 E:Z). For the first time, the olefin scope encompasses unactivated aliphatic olefins as well as activated aromatic/heteroaromatic olefins and 1,4-dienes. The ease of appending allyl moieties onto complex scaffolds is leveraged to enable this mild and selective allylic C–H alkylation to rapidly diversify phenolic natural products. The tertiary nucleophile scope is broad and includes latent functionality for further elaboration (e.g., aliphatic alcohols, α,β-unsaturated esters). The opportunities to effect synthetic streamlining with such general C–H reactivity are illustrated in an allylic C–H alkylation/Diels–Alder reaction cascade: a reactive diene is generated via intermolecular allylic C–H alkylation and approximated to a dienophile contained within the tertiary nucleophile to furnish a common tricyclic core found in the class I galbulimima alkaloids.

    Taran-Benshoshan, Marina; Ofer, Naomi; Dalit, Vaizel-Ohayon; Aharoni, Avi; Revhun, Menahem; Nitzan, Yeshayahu; Nasser, Abidelfatah M


    Wastewater disposal may be a source of environmental contamination by Cryptosporidium and Giardia. This study was conducted to evaluate the prevalence of Cryptosporidium oocysts and Giardia cysts in raw and treated wastewater effluents. A prevalence of 100% was demonstrated for Giardia cysts in raw wastewater, at a concentration range of 10 to 12,225 cysts L(-1), whereas the concentration of Cryptosporidium oocysts in raw wastewater was 4 to 125 oocysts L(-1). The removal of Giardia cysts by secondary and tertiary treatment processes was greater than those observed for Cryptosporidium oocysts and turbidity. Cryptosporidium and Giardia were present in 68.5% and 76% of the tertiary effluent samples, respectively, at an average concentration of 0.93 cysts L(-1) and 9.94 oocysts L(-1). A higher detection limit of Cryptosporidium oocysts in wastewater was observed for nested PCR as compared to immune fluorescent assay (IFA). C. hominis was found to be the dominant genotype in wastewater effluents followed by C. parvum and C. andersoni or C. muris. Giardia was more prevalent than Cryptosporidium in the studied community and treatment processes were more efficient for the removal of Giardia than Cryptosporidium. Zoonotic genotypes of Cryptosporidium were also present in the human community. To assess the public health significance of Cryptosporidium oocysts present in tertiary effluent, viability (infectivity) needs to be assessed.

  6. Mudflow utilization for construction materials of tertiary irrigation canal lining (United States)

    Azis, Subandiyah; Kustamar


    Mudflow in Siring Village, Sidoarjo Regency, Indonesia, has been in eruption since May 29, 2006. It still shows irregular large bursts which loaded in a sludge reservoir with capacity of 59 million m3. From 2007 until 2015, there were more than 20 studies which concluded that the mudflow could be used as a mixture of building materials. However, the studies were not detailed and needed further research. This research aims to investigate the use of mudflow as tertiary irrigation canal lining material. This research comes with several laboratory tests to obtain a mixture that is solid and water-resistant. The methods that were used are descriptive methods as follows: 1). Sampling of mudflow, to be analyzed in Material Testing Laboratory. 2). Sampling of soil at research site, to be analyzed in Soil Mechanics Laboratory 3). Mixing of materials which are consist of mudflow and other materials and doing strength test in the laboratory. 4). Installation of tertiary irrigation canal lining using materials that have been tested. 5). Observation of lining's strength inactive soil pressure-bearing and its impermeability. It is expected that the results of this research will be applied extensively throughout the tertiary irrigation canals, so mudflow can be utilized as raw materials that are environmentally friendly, which are able to help preserving the environment, also to reduce the removal of sand / rock in the river, which has been used for lining materials, that benefits in preventing damage to the river ecosystem.

  7. Frozen Chirality of Tertiary Aromatic Amides: Access to Enantioenriched Tertiary α-Amino Acid or Amino Alcohol without Chiral Reagent. (United States)

    Mai, Thi Thoa; Viswambharan, Baby; Gori, Didier; Guillot, Régis; Naubron, Jean-Valère; Kouklovsky, Cyrille; Alezra, Valérie


    One of the fundamental and intriguing aspects of life is the homochirality of the essential molecules. In this field, the absolute asymmetric synthesis of α-amino acids is a major challenge. Herein, we report access, by chemical means, to tertiary α-amino acid derivatives in up to 96 % ee without using any chiral reagent. In our strategy, the dynamic axial chirality of tertiary aromatic amides is frozen in a crystal and is responsible for the stereoselectivity of the subsequent steps. Furthermore, we could control the configuration of the final product by manually sorting and selecting the initial crystals. Based on vibrational circular dichroism studies, we could rationalize the observed stereoselectivity. © 2017 Wiley-VCH Verlag GmbH & Co. KGaA, Weinheim.

  10. Back transport: exploration of parents' feelings regarding the transition. (United States)

    Kuhnly, J E; Freston, M S


    The purpose of this qualitative study was to explore parents' perceptions and the concepts involved in their preterm infant's back transport from a tertiary neonatal intensive care unit to their home community hospital. A convenience sample of fourteen parents were interviewed five to seven days after the back transport. Following data collection, the analysis of the parents' perceptions regarding the back transport of their premature infant identified a crisis theme that was influenced by several concepts. The subject's positive or negative meaning of the back transport during the pre-crisis phase defined the extent of the crisis during a three day transition period which led to an acceptance of events in the resolution phase. The subjects' perceptions of the previous events of hospitalization and communication of information regarding back transport influenced the meaning of the back transport for them. The extent of crisis during the transition phase was influenced by subjects' perceptions of medical complications, caretaking practice changes, environmental changes, feelings of powerlessness or empowerment, personal coping resources, and support systems available. Resolution in all cases occurred with an acceptance of events. Implications for practice and future research can be identified such as developing and testing education programs to prepare parents for the transition and strengthening the relationship between tertiary and community hospitals.

  11. Tertiary survey in polytrauma patients should be an ongoing process. (United States)

    Ferree, Steven; Houwert, Roderick M; van Laarhoven, Jacqueline J E M; Smeeing, Diederik P J; Leenen, Luke P H; Hietbrink, Falco


    Due to prioritisation in the initial trauma care, non-life threatening injuries can be overlooked or temporally neglected. Polytrauma patients in particular might be at risk for delayed diagnosed injuries (DDI). Studies that solely focus on DDI in polytrauma patients are not available. Therefore the aim of this study was to analyze DDI and determine risk factors associated with DDI in polytrauma patients. In this single centre retrospective cohort study, patients were considered polytrauma when the Injury Severity Score was ≥ 16 as a result of injury in at least 2 body regions. Adult polytrauma patients admitted from 2007 until 2012 were identified. Hospital charts were reviewed to identify DDI. 1416 polytrauma patients were analyzed of which 12% had DDI. Most DDI were found during initial hospital admission after tertiary survey (63%). Extremities were the most affected regions for all types of DDI (78%) with the highest intervention rate (35%). Most prevalent DDI were fractures of the hand (54%) and foot (38%). In 2% of all patients a DDI was found after discharge, consisting mainly of injuries other than a fracture. High energy trauma mechanism (OR 1.8, 95% CI 1.2-2.7), abdominal injury (OR 1.5, 95% CI 1.1-2.1) and extremity injuries found during initial assessment (OR 2.3, 95% CI 1.6-3.3) were independent risk factors for DDI. In polytrauma patients, most DDI were found during hospital admission but after tertiary survey. This demonstrates that the tertiary survey should be an ongoing process and thus repeated daily in polytrauma patients. Most frequent DDI were extremity injuries, especially injuries of the hand and foot. Copyright © 2015 Elsevier Ltd. All rights reserved.

  12. Intense acidic volcanism at the Cretaceous-Tertiary boundary

    International Nuclear Information System (INIS)

    Javoy, M.; Courtillot, V.


    A 87 Sr/ 86 Sr spike in seawater strontium with amplitude 2 x 10 -4 and duration of order 2 Ma is superimposed on longer-term variations at the Cretaceous-Tertiary boundary. The anomaly has been attributed to increased continental runoff due either to meteorite impact-related acid rain or sea-level regression. We speculate here that the spike could have resulted from intense, explosive acid volcanism preceding the development of the Deccan traps. A good model, both in tectonic position and geochemical characteristics, for these as yet elusive acidic products is provided by granites in the Seychelles Islands and particularly Mahe. (orig.)

  13. Loop Entropy Assists Tertiary Order: Loopy Stabilization of Stacking Motifs

    Directory of Open Access Journals (Sweden)

    Daniel P. Aalberts


    Full Text Available The free energy of an RNA fold is a combination of favorable base pairing and stacking interactions competing with entropic costs of forming loops. Here we show how loop entropy, surprisingly, can promote tertiary order. A general formula for the free energy of forming multibranch and other RNA loops is derived with a polymer-physics based theory. We also derive a formula for the free energy of coaxial stacking in the context of a loop. Simulations support the analytic formulas. The effects of stacking of unpaired bases are also studied with simulations.

  14. Proximal Cretaceous-Tertiary boundary impact deposits in the Caribbean (United States)

    Hildebrand, Alan R.; Boynton, Willam V.


    Trace element, isotopic, and mineralogic studies indicate that the proposed impact at the Cretaceous-Tertiary boundary occurred in an ocean basin, although a minor component of continental material is required. The size and abundance of shocked minerals and the restricted geographic occurrence of the ejecta layer and impact-wave deposits suggest an impact between the Americas. Coarse boundary sediments at sites 151 and 153 in the Colombian Basin and 5- to 450-meter-thick boundary sediments in Cuba may be deposits of a giant wave produced by a nearby oceanic impact.

  15. Uranium in tertiary stream channels, Lake Frome area, South Australia

    International Nuclear Information System (INIS)

    Brunt, D.A.


    Uranium exploration over a wide area of the Southern Frome Embayment, South Australia, has defined a number of Lower Tertiary fluvial palacochannels incised in older rocks. The buried channels contain similar stratigraphic sequences of interbedded sand, silt, and clay, probably derived from the adjacent uranium-rich Olary Province. Uranium mineralization is pervasive within two major palacochannels, and four small uranium deposits have been found in the basal sands of these channel sequences, at the margins of extensive tongues of limonitic sand. A genetic model is proposed suggesting formation by a uraniferous geochemical cell which migrated down the stream gradient and concentrated uranium on its lateral margins adjacent to the channel bank

    Huber, T S; Carlton, L M; O'Hern, D G; Hardt, N S; Keith Ozaki, C; Flynn, T C; Seeger, J M


    To analyze the financial impact of three complex vascular surgical procedures to both an academic hospital and a department of surgery and to examine the potential impact of decreased reimbursements. The cost of providing tertiary care has been implicated as one potential cause of the financial difficulties affecting academic medical centers. Patients undergoing revascularization for chronic mesenteric ischemia, elective thoracoabdominal aortic aneurysm repair, and treatment of infected aortic grafts at the University of Florida were compared with those undergoing elective infrarenal aortic reconstruction and carotid endarterectomy. Hospital costs and profit summaries were obtained from the Clinical Resource Management Office. Departmental costs and profit summary were estimated based on the procedural relative value units (RVUs), the average clinical cost per RVU ($33.12), surgeon charges, and the collection rate for the vascular surgery division (30.2%) obtained from the Faculty Group Practice. Surgeon work effort was analyzed using the procedural work RVUs and the estimated total care time. The analyses were performed for all payors and the subset of Medicare patients, and the potential impact of a 15% reduction in hospital and physician reimbursement was analyzed. Net hospital income was positive for all but one of the tertiary care procedures, but net losses were sustained by the hospital for the mesenteric ischemia and infected aortic graft groups among the Medicare patients. In contrast, the estimated reimbursement to the department of surgery for all payors was insufficient to offset the clinical cost of providing the RVUs for all procedures, and the estimated losses were greater for the Medicare patients alone. The surgeon work effort was dramatically higher for the tertiary care procedures, whereas the reimbursement per work effort was lower. A 15% reduction in reimbursement would result in an estimated net loss to the hospital for each of the tertiary

  17. Bahrain’s tertiary education reform : a step towards sustainable economic development

    Directory of Open Access Journals (Sweden)

    Magdalena Karolak


    Full Text Available Bahrain has been experiencing along with other Gulf Council Cooperation countries a rapid development of its tertiary sector of education. The 2000's were marked by a boom in education with the opening of twelve private universities in this country of roughly 1 million inhabitants. Some institutions were locally based, while others worked in affiliation with foreign based universities. It is in sharp contrast with the 1990's, when only three public universities served as centers of higher education. The reasons behind this large-scale expansion of higher education include the growth of local and expatriate population, the planned transition from oil industry to a knowledge-based economy as well as the growing role of women in the workforce. All of these factors need to be addressed in order to assure a stable social and economic development, and education is the backbone of both. This paper examines the recent initiatives undertaken in Bahrain to monitor and ensure the quality of education of cross-border educational institutions as well as that of local education providers.

  18. Initiation of a medical toxicology consult service at a tertiary care children's hospital. (United States)

    Wang, George Sam; Monte, Andrew; Hatten, Benjamin; Brent, Jeffrey; Buchanan, Jennie; Heard, Kennon J


    Currently, only 10% of board-certified medical toxicologists are pediatricians. Yet over half of poison center calls involve children toxicology consultation is not common at children's hospitals. In collaboration with executive staff from Department of Pediatrics and Emergency Medicine, regional poison center, and our toxicology fellowship, we established a toxicology consulting service at our tertiary-care children's hospital. There were 139 consultations, and the service generated 13 consultations in the first month; median of 11 consultations per month thereafter (range 8-16). The service increased pediatric cases seen by the fellowship program from 30 to 94. The transition to a consult service required a culture change. Historically, call center advice was the mainstay of consulting practice and the medical staff was not accustomed to the availability of bedside medical toxicology consultations. However, after promotion of the service and full attending and fellowship coverage, consultations increased. In collaboration with toxicologists from different departments, a consultation service can be rapidly established. The service filled a clinical need that was disproportionately utilized for high acuity patients, immediately utilized by the medical staff and provided a robust pediatric population for the toxicology fellowship.

    Full Text Available Despite the widespread notion amongst chemistry educators that the laboratory is essential to learn chemistry, it is often a neglected area of teaching and, arguably, of educational research. Research has typically focused on secondary education, single institutions, and isolated interventions that are mostly assessed quantitatively. It has also honed in on compartmentalised features instead of searching understanding of broader aspects of learning through experimentation. This paper contends there is a gap in subject specific, tertiary level research that is comprehensive and learning-centred instead of fragmented and instruction-based. A shift in focus requires consideration of methodological approaches that can effectively tackle the challenges of researching complex learning environments. This paper reckons qualitative approaches, specifically phenomenology, are better suited for this purpose. To illustrate this potential, it summarises an exemplar phenomenological study that investigated students’ experience of change in instructional style from an expository (traditional laboratory program to one that was cooperative and project-based (reformed. The study suggests the experience was characterised by a transition from a learning environment that promoted mindless behaviour to one in which students were mindfully engaged in their learning. Thus, this work puts forth the use of Mindfulness Theory to investigate and support design of laboratory experiences.

  2. Study of electron transition energies between anions and cations in spinel ferrites using differential UV–vis absorption spectra

    International Nuclear Information System (INIS)

    Xue, L.C.; Wu, L.Q.; Li, S.Q.; Li, Z.Z.; Tang, G.D.; Qi, W.H.; Ge, X.S.; Ding, L.L.


    It is very important to determine electron transition energies (E_t_r) between anions and different cations in order to understand the electrical transport and magnetic properties of a material. Many authors have analyzed UV–vis absorption spectra using the curve (αhν)"2 vs E, where α is the absorption coefficient and E(=hν) is the photon energy. Such an approach can give only two band gap energies for spinel ferrites. In this paper, using differential UV–vis absorption spectra, dα/dE vs E, we have obtained electron transition energies (E_t_r) between the anions and cations, Fe"2"+ and Fe"3"+ at the (A) and [B] sites and Ni"2"+ at the [B] sites for the (A)[B]_2O_4 spinel ferrite samples Co_xNi_0_._7_−_xFe_2_._3O_4 (0.0≤x≤0.3), Cr_xNi_0_._7Fe_2_._3_−_xO_4 (0.0≤x≤0.3) and Fe_3O_4. We suggest that the differential UV–vis absorption spectra should be accepted as a general analysis method for determining electron transition energies between anions and cations.

  3. Quantum phase transitions

    International Nuclear Information System (INIS)

    Sachdev, S.


    Phase transitions are normally associated with changes of temperature but a new type of transition - caused by quantum fluctuations near absolute zero - is possible, and can tell us more about the properties of a wide range of systems in condensed-matter physics. Nature abounds with phase transitions. The boiling and freezing of water are everyday examples of phase transitions, as are more exotic processes such as superconductivity and superfluidity. The universe itself is thought to have passed through several phase transitions as the high-temperature plasma formed by the big bang cooled to form the world as we know it today. Phase transitions are traditionally classified as first or second order. In first-order transitions the two phases co-exist at the transition temperature - e.g. ice and water at 0 deg., or water and steam at 100 deg. In second-order transitions the two phases do not co-exist. In the last decade, attention has focused on phase transitions that are qualitatively different from the examples noted above: these are quantum phase transitions and they occur only at the absolute zero of temperature. The transition takes place at the ''quantum critical'' value of some other parameter such as pressure, composition or magnetic field strength. A quantum phase transition takes place when co-operative ordering of the system disappears, but this loss of order is driven solely by the quantum fluctuations demanded by Heisenberg's uncertainty principle. The physical properties of these quantum fluctuations are quite distinct from those of the thermal fluctuations responsible for traditional, finite-temperature phase transitions. In particular, the quantum system is described by a complex-valued wavefunction, and the dynamics of its phase near the quantum critical point requires novel theories that have no analogue in the traditional framework of phase transitions. In this article the author describes the history of quantum phase transitions. (UK)

    Ectopic (or tertiary) lymphoid tissue develops at sites of inflammation or infection in non lymphoid organs and is associated with chronic inflammation. In colon mucosa, small lymphoid aggregates are already present in homeostatic conditions, as part of the gut-associated lymphoid tissue and play an essential role in the immune response to perturbations of the mucosal microenvironment. Despite the recognized role of inflammation in tumor progression, the presence and biological function of lymphoid tissue in cancer has been poorly investigated. We identified aggregates of lymphocytes resembling tertiary lymphoid tissue in human colorectal cancer specimens; intratumor accumulations of lymphocytes display a high degree of compartmentalization, with B and T cells, mature dendritic cells and a network of CD21{sup +} follicular dendritic cells (FDC). We analyzed the adaptation of colon lymphoid tissue in a murine model of colitis-associated cancer (AOM/DSS). B cell follicle formation increases in the context of the chronic inflammation associated to intestinal neoplasia, in this model. A network of lymphatic and haematic vessels surrounding B cell follicles is present and includes high endothelial venules (HEV). Future task is to determine whether lymphoid tissue contributes to the persistence of the tumor-associated inflammatory reaction, rather than represent a functional immune compartment, potentially participating to the anti tumor response.

    Full Text Available For tertiary English as a Foreign Language (EFL students, academic writing is not an easy task. It requires knowledge of the academic writing genres with their particular linguistic features. Moreover, academic writing demands good critical thinking. This research aims to explore the students' academic writing competencies that also focus on critical thinking. The research involved thirty-six first-year tertiary EFL students from a regular class of a private university in Pontianak, West Kalimantan, Indonesia. The source for data collection was the students’ texts. Three texts were selected and the students were categorized into low, medium, and high levels of writing achievement. The text analysis utilized functional grammar rooted in systemic functional linguistics (Emilia, 2014. The analysis shows that the students, regardless of their levels of writing achievement, have little control over the schematic structure and linguistic features of an argumentative writing. The text analysis also shows that the students’ texts have some limitations as regards their critical thinking capacity. Still, a few examples of academic language were detected in the texts. The findings suggest that the lecturer should incorporate explicit teaching and cooperative learning activities to alleviate the students' difficulties and develop their academic writing and critical thinking capacity.

    Schmassmann, H.; Kullin, M.; Wexsteen, P.


    This Tertiary-Malm synthesis represents the first part of an overall hydrochemical synthesis of deep groundwaters in Northern Switzerland and adjacent areas. The investigation is mainly based on data from Nagra deep boreholes, from Nagra regional programme as well as from external sources. The first part provides a hydrogeological overview including a brief description of the aquifer rocks. A compilation of all existing hydraulic potential data is given and discussed for Northern Switzerland, Bodensee area and western Swabian Alb. In the Molasse Basin, hydrochemical and isotope analyses allowed a distinction of three main water types positioned one upon another: calcium-magnesium-bicarbonate groundwaters, sodium-bicarbonate and sodium-chloride deep groundwaters. Hydrochemical and isotopegeochemical details of these three water types comprise the major part of this report. Unlike the other two water types, the calcium-magnesium-bicarbonate groundwaters also include shallow waters with considerable tritium activities, indicating a mean residence time of less than 35 years. The spacial distribution of these three water types are demonstrated and different secular flow models in the Tertiary-Malm Aquifer group are discussed. (author) figs., tabs., 194 refs

  17. Halitosis amongst students in tertiary institutions in Lagos state. (United States)

    Arinola, J E; Olukoju, O O


    Halitosis is defined as a noticeable unpleasant odor from the mouth. It is a medico-social problem that affects a significant number of people around the world. Research reveals that nearly 50% of the adult population has halitosis. To determine level of awareness of halitosis and prevalence of the condition amongst students in tertiary institutions as a baseline survey. For this project, 100 students from three tertiary institutions in Lagos state were chosen: University of Lagos, Lagos State University, Ojo campus and Yaba College of Technology. A semi-structured questionnaire and practical testing/diagnostic tool were utilized. Data collected was collated and analyzed using Microsoft Excel 2007 and SPSS statistical software. Most of the respondents were single and Christian. Level of awareness of halitosis was high. Results showed that 15%, 2% and 22% from UNILAG, LASU and YCT respectively said they had halitosis. Using the diagnostic tool, 6%, 8% and 2% respectively were positive for halitosis. There is high level of awareness of halitosis among the respondents. The prevalence of the disorder is low, however, it is recommended that enlightenment campaigns be mounted in schools to improve level of awareness and treatment seeking.

Despite learning in a “rote” manner during their formative years, students have adapted to deeper learning approaches although there is a still a slight but insignificant bias to surface learning. They desire to achieve and get good marks although strategy is limiting their progress. According to Biggs, this is commonly caused by a language problem.

  19. Extraterrestrial cause for the Cretaceous-Tertiary extinction

    International Nuclear Information System (INIS)

    Alvarez, L.W.; Alvarez, W.; Asaro, F.; Michel, H.V.


    Platinum metals are depleted in the earth's crust relative to their cosmic abundance; concentrations of these elements in deep-sea sediments may thus indicate influxes of extraterrestrial material. Deep-sea limestones exposed in Italy, Denmark, and New Zealand show iridium increases of about 30, 160, and 20 times, respectively, above the background level at precisely the time of the Cretaceous-Tertiary extinctions, 65 million years ago. Reasons are given to indicate that this iridium is of extraterrestrial origin, but did not come from a nearby supernova. A hypothesis is suggested which accounts for the extinctions and the iridium observations. Impact of a large earth-crossing asteroid would inject about 60 times the object's mass into the atmosphere as pulverized rock; a fraction of this dust would stay in the stratosphere for several years and be distributed worldwide. The resulting darkness would suppress photosynthesis, and the expected biological consequences match quite closely the extinctions observed in the paleontological record. One prediction of this hypothesis has been verified: the chemical composition of the boundary clay, which is thought to come from the stratospheric dust, is markedly different from that of clay mixed with the Cretaceous and Tertiary limestones, which are chemically similar to each other. Four different independent estimates of the diameter of the asteroid give values that lie in the range 10 +- 4 kilometers

    Ectopic (or tertiary) lymphoid tissue develops at sites of inflammation or infection in non lymphoid organs and is associated with chronic inflammation. In colon mucosa, small lymphoid aggregates are already present in homeostatic conditions, as part of the gut-associated lymphoid tissue and play an essential role in the immune response to perturbations of the mucosal microenvironment. Despite the recognized role of inflammation in tumor progression, the presence and biological function of lymphoid tissue in cancer has been poorly investigated. We identified aggregates of lymphocytes resembling tertiary lymphoid tissue in human colorectal cancer specimens; intratumor accumulations of lymphocytes display a high degree of compartmentalization, with B and T cells, mature dendritic cells and a network of CD21 + follicular dendritic cells (FDC). We analyzed the adaptation of colon lymphoid tissue in a murine model of colitis-associated cancer (AOM/DSS). B cell follicle formation increases in the context of the chronic inflammation associated to intestinal neoplasia, in this model. A network of lymphatic and haematic vessels surrounding B cell follicles is present and includes high endothelial venules (HEV). Future task is to determine whether lymphoid tissue contributes to the persistence of the tumor-associated inflammatory reaction, rather than represent a functional immune compartment, potentially participating to the anti tumor response

  1. Secondary and tertiary hyperparathyroidism in chronic kidney disease

    Lilit V. Egshatyan


    Full Text Available In the treatment of secondary hyperparathyroidism of end-stage chronic kidney disease, vitamin D receptor activation and allosteric modulators of the calcium-sensing receptor – inhibit glandular hyperplasia, reduce parathyroid hormone levels, impact on bone turnover and mineral density. But the use of calcimimetic and vitamin D analogs or mimetics did not reduce the need for parathyroidectomy for refractory hyperparathyroidism. The enlarged parathyroid gland and gland nodular transformation became refractory to medical therapy and patient need for parathyroidectomy. Tertiary hyperparathyroidism is a state of excessive secretion of parathyroid hormone after a long period of secondary hyperparathyroidism and renal transplantation. In this article, we present the case of a Caucasian male with chronic kidney disease (end-stage on chronic hemodialysis and after kidney transplantation and different forms of hyperparathyroidism (secondary and tertiary. Our case study shows that only a multi-interventional strategy is likely to be more effective treatment in cases of severe and refractory to medical therapy hyperparathyroidism.

  2. Reflections on entrepreneurship education in African tertiary institutions

    Directory of Open Access Journals (Sweden)

    K. Bawuah


    Full Text Available It is a well-established fact that several developed economies grew on the back of small businesses and entrepreneurial development. It stands to reason then that the development of Sub-Saharan Africa (SSA can also be catalysed by a rise in the number of entrepreneurs and entrepreneurial activity. In that general regard, this paper sought to investigate the state of entrepreneurship education in Sub-Saharan Africa (SSA. The method adopted in investigating this phenomenon was to critique the existing tertiary education entrepreneurship structures (where these existed at all and to proffer recommendations where anomalies were discovered. It came to light that despite the critical importance of entrepreneurs in the economic development of a nation, Sub-Saharan African (SSA countries have not fully developed strategies to tap this resource. What the countries have, are haphazard policies designed to promote the lesser or uneducated individuals in the informal sector into entrepreneurship. SSA educational leaders must find ways to structure their curricula so that all or most of their students can take courses in entrepreneurship. This is essential for SSA countries in order to move them from their present disadvantaged economic status, to greater economic and social development. A tentative syllabus for African tertiary education is proffered at the end of the article but its robustness needs to be tested.

    Bukhary, Zakeya A.; Alrajhi, Abdulrahman A.


    The outcome of the chemotherapy for pulmonary, extraplumonary and disseminated tuberculosis is not well documented, especially in developing countries. This study assessed tuberculosis treatment outcome, cure-to-treatment ratio and mortality among all types of tuberculosis patients in a tertiary care setting in Saudi Arabia. All cases diagnosed and treated for active Mycobacterium tuberculosis infection between 1991 and 2000 were included retrospectively. Data collected included type of tuberculosis involvement, treatment outcome, relapse and co-morbidities. Over a ten-year period, 535 case of tuberculosis were diagnosed and treated. Isolated pulmonary tuberculosis was identified in 141 cases (26.4%), extrapulmonary tuberculosis in 339 cases (63.3%). Co-morbidities were noted in 277 (52%) patients. Immunosuppression was found in 181 (34%) cases. The cure rate was 82%. The cure-to-treatment ratio was 86% in extrapulmonary tuberculosis and 65% in disseminated tuberculosis. Overall mortality was 18%. Disseminated tuberculosis had the highest mortality (34.9%), followed by pulmonary (21.8%), the extrapulmonary tuberculosis (13.6%). Forty-seven percent of all mortalities were directly related to tuberculosis. Relapse was documented in 14 out of 349 patients (4%) who had 24 months of follow-up. Despite tertiary care support, complicated tuberculosis carries a high mortality. Earlier diagnosis and complete appropriate chemotherapy are essential for improved outcome. (author)

  5. Gifts from Exoplanetary Transits (United States)

    Narita, Norio


    The discovery of transiting extrasolar planets has enabled us to do a number of interesting studies. Transit photometry reveals the radius and the orbital inclination of transiting planets, which allows us to learn the true mass and density of the respective planets by the combined information from radial velocity (RV) measurements. In addition, follow-up observations of transiting planets, looking at such things as secondary eclipses, transit timing variations, transmission spectroscopy, and the Rossiter-McLaughlin effect, provide us information about their dayside temperatures, unseen bodies in systems, planetary atmospheres, and the obliquity of planetary orbits. Such observational information, which will provide us a greater understanding of extrasolar planets, is available only for transiting planets. Here, I briefly summarize what we can learn from transiting planets and introduce previous studies.

  4. Entrepreneurship Education at Tertiary Education Level: Implication to Historical Studies

    Directory of Open Access Journals (Sweden)

    Salahu Mohammed Lawal


    Full Text Available Nigeria is richly endowed with both human and material resources that when well utilized can make her one of the richest and developed nation in the world.  But poor utilization of the resources, corruption and dwindling fortune in her education system made her among the first twenty five poorest nations in the world.  Similarly, report shows that 26% of the employable population remained unemployed.  This called for the need for entrepreneurship education most especially at tertiary level where high level manpower is supposed to be trained.  It is on this premise that the paper attempts to examine entrepreneurship education and its implication to history students and graduates.

  5. Tertiary proton diagnostics in future inertial confinement fusion experiments

    International Nuclear Information System (INIS)

    Cremer, S.; Verdon, C.P.; Petrasso, R.D.


    Recently, it was proposed to use energetic (up to 31 MeV) tertiary protons produced during the final stage of inertial confinement fusion implosions to measure the fuel areal density of compressed deuterium endash tritium (DT). The method is based on seeding the fuel with 3 He. The reaction of 3 He ions with the energetic knock-on deuterons, produced via the elastic scattering of 14.1 MeV neutrons, is a source of very energetic protons capable of escaping from very large areal density targets. This work presents results of detailed time-dependent Monte Carlo simulations of the nuclear processes involved in producing and transporting these protons through imploding targets proposed for direct-drive experiments on OMEGA [D. K. Bradley et al., Phys. Plasmas 5, 1870 (1998)] and the National Ignition Facility [S. W. Haan et al., Phys. Plasmas 2, 2480 (1995)]. copyright 1998 American Institute of Physics

  8. Cooperative activity and its potential for learning in tertiary education

    Directory of Open Access Journals (Sweden)

    Cirila Peklaj


    Full Text Available A learning situation can be structured in different ways, as an individual, competitive, or cooperative activity. Each of these structures can be used for different purposes and can lead to different learning outcomes. This paper focuses on cooperative activity and its potential for learning in tertiary education. After defining cooperative activity (or, in a broader sense, learning in interaction and introducing the CAMS theoretical framework to analyse cooperative activity, the main discussion focuses on the theoretical reasons for the usefulness of group learning and on the research of effects of cooperative learning on cognitive (metacognitive, affective-motivational and social processes in university students. The key elements that should be established for successful cooperation are also discussed. At the end, a new direction in using cooperative activity in learning—computer supported collaborative learning (CSCL, which emerged with rapid technology development in the last two decades—is presented and discussed.

  9. Constructivism in Teaching English for Special Purposes at Tertiary School

    Directory of Open Access Journals (Sweden)

    Anna Y. Polenova


    Full Text Available The article looks at some principles of constructivism philosophy and the ways they are realized in ESP teaching at tertiary school. The purpose of this article is to describe constructivist teaching approach in enhancing students’ use of appropriate ESP learning strategies. Constructivism is a theory that emphasizes the active role of students in building understanding and making sense of the information. The constructivist teaching is learner-centered where students are actively involved in knowledge construction rather than passive listeners. Students construct knowledge by transforming, organizing, reorganizing previous knowledge through social interaction in construction of knowledge and understanding. The paper is an attempt to examine the principles of constructivist teaching and learning by providing analysis of features of constructivist theory and the organization of a constructivist classroom.

    AUTHOR|(CDS)2085459; Bertarelli, Alessandro; Bruce, Roderik; Carra, Federico; Cerutti, Francesco; Gradassi, Paolo; Lechner, Anton; Redaelli, Stefano; Skordis, Eleftherios


    The tertiary collimators (TCTs) in the LHC, installed in front of the experiments, in standard operation intercept fractions of 10−3 halo particles. However, they risk to be hit by high-intensity primary beams in case of asynchronous beam dump. TCT damage thresholds were initially inferred from results of destructive tests on a TCT jaw, supported by numerical simulations, assuming simplified impact scenarios with one single bunch hitting the jaw with a given impact parameter. In this paper, more realistic failure conditions, including a train of bunches and taking into account the full collimation hierarchy, are used to derive updated damage limits. The results are used to update the margins in the collimation hierarchy and could thus potentially have an influence on the LHC performance.

  13. Tertiary alphabet for the observable protein structural universe. (United States)

    Mackenzie, Craig O; Zhou, Jianfu; Grigoryan, Gevorg


    Here, we systematically decompose the known protein structural universe into its basic elements, which we dub tertiary structural motifs (TERMs). A TERM is a compact backbone fragment that captures the secondary, tertiary, and quaternary environments around a given residue, comprising one or more disjoint segments (three on average). We seek the set of universal TERMs that capture all structure in the Protein Data Bank (PDB), finding remarkable degeneracy. Only ∼600 TERMs are sufficient to describe 50% of the PDB at sub-Angstrom resolution. However, more rare geometries also exist, and the overall structural coverage grows logarithmically with the number of TERMs. We go on to show that universal TERMs provide an effective mapping between sequence and structure. We demonstrate that TERM-based statistics alone are sufficient to recapitulate close-to-native sequences given either NMR or X-ray backbones. Furthermore, sequence variability predicted from TERM data agrees closely with evolutionary variation. Finally, locations of TERMs in protein chains can be predicted from sequence alone based on sequence signatures emergent from TERM instances in the PDB. For multisegment motifs, this method identifies spatially adjacent fragments that are not contiguous in sequence-a major bottleneck in structure prediction. Although all TERMs recur in diverse proteins, some appear specialized for certain functions, such as interface formation, metal coordination, or even water binding. Structural biology has benefited greatly from previously observed degeneracies in structure. The decomposition of the known structural universe into a finite set of compact TERMs offers exciting opportunities toward better understanding, design, and prediction of protein structure.

    The phenomenology of the phase transitions has been considered. The definitions of thermodynamic functions and parameters, as well as those of the phase transitions, are given and some of the relations between those quantities are discussed. The phase transitions classification proposed by Ehrenfest has been described. The most important features of phase transitions are discussed using the selected physical examples including the critical behaviour of ferromagnetic materials at the Curie temperature and antiferromagnetic materials at the Neel temperature. Some aspects of the Ehrenfest's equations, that have been derived, for the interfacial lines and surfaces are considered as well as the role the notion of interfaces. (S.B.)

  20. Eigenstate Phase Transitions (United States)

    Zhao, Bo

    Phase transitions are one of the most exciting physical phenomena ever discovered. The understanding of phase transitions has long been of interest. Recently eigenstate phase transitions have been discovered and studied; they are drastically different from traditional thermal phase transitions. In eigenstate phase transitions, a sharp change is exhibited in properties of the many-body eigenstates of the Hamiltonian of a quantum system, but not the thermal equilibrium properties of the same system. In this thesis, we study two different types of eigenstate phase transitions. The first is the eigenstate phase transition within the ferromagnetic phase of an infinite-range spin model. By studying the interplay of the eigenstate thermalization hypothesis and Ising symmetry breaking, we find two eigenstate phase transitions within the ferromagnetic phase: In the lowest-temperature phase the magnetization can macroscopically oscillate by quantum tunneling between up and down. The relaxation of the magnetization is always overdamped in the remainder of the ferromagnetic phase, which is further divided into phases where the system thermally activates itself over the barrier between the up and down states, and where it quantum tunnels. The second is the many-body localization phase transition. The eigenstates on one side of the transition obey the eigenstate thermalization hypothesis; the eigenstates on the other side are many-body localized, and thus thermal equilibrium need not be achieved for an initial state even after evolving for an arbitrary long time. We study this many-body localization phase transition in the strong disorder renormalization group framework. After setting up a set of coarse-graining rules for a general one dimensional chain, we get a simple "toy model'' and obtain an almost purely analytical solution to the infinite-randomness critical fixed point renormalization group equation. We also get an estimate of the correlation length critical exponent nu

  6. Matter in transition

    International Nuclear Information System (INIS)

    Anderson, Lara B.; Gray, James; Raghuram, Nikhil; Taylor, Washington


    We explore a novel type of transition in certain 6D and 4D quantum field theories, in which the matter content of the theory changes while the gauge group and other parts of the spectrum remain invariant. Such transitions can occur, for example, for SU(6) and SU(7) gauge groups, where matter fields in a three-index antisymmetric representation and the fundamental representation are exchanged in the transition for matter in the two-index antisymmetric representation. These matter transitions are realized by passing through superconformal theories at the transition point. We explore these transitions in dual F-theory and heterotic descriptions, where a number of novel features arise. For example, in the heterotic description the relevant 6D SU(7) theories are described by bundles on K3 surfaces where the geometry of the K3 is constrained in addition to the bundle structure. On the F-theory side, non-standard representations such as the three-index antisymmetric representation of SU(N) require Weierstrass models that cannot be realized from the standard SU(N) Tate form. We also briefly describe some other situations, with groups such as Sp(3), SO(12), and SU(3), where analogous matter transitions can occur between different representations. For SU(3), in particular, we find a matter transition between adjoint matter and matter in the symmetric representation, giving an explicit Weierstrass model for the F-theory description of the symmetric representation that complements another recent analogous construction.

  11. Tertiary Technical Education and Youth Integration in Brazil, Colombia and Mexico

    Directory of Open Access Journals (Sweden)

    Claudia Jacinto


    Full Text Available Vocational training versus a traditional university education. This chapter seeks to answer the question of whether ‘tertiary technical education’ has contributed to increasing economic and social opportunity for young people in Latin America, using three case studies from Brazil, Colombia and Mexico. It examines the extent to which tertiary technical education has contributed towards democratising access to education through institutional diversification, expanded enrolment and, at least theoretically, improved access to quality employment. The analysis shows that tertiary technical education has contributed to widening of opportunities by offering an alternative form of education to new generations of young people. Tertiary technical education is more accessible, shorter in duration, has a vocational orientation, and tends to be cheaper than a university education. However, the case studies also reveal that while a tertiary technical education diploma is an asset for young people seeking employment, it nonetheless does not have the same perceived value as a traditional university education. Available data appear to indicate that graduates of tertiary technical education earn less on average than university graduates and face several challenges in the labour market. Furthermore, the studies reveal that despite the presence of highly regarded tertiary technical education institutions in all three countries, these carry less prestige and status than universities.

    Full Text Available This study investigates the impact of different schooling dimensions (primary, secondary and tertiary on the intensity of intra-state conflicts in 25 African states during the period 1989–2008. It uses fixed-effects and Generalized Methods of Moments (GMM estimators in an annualized panel data framework. Parameter estimates suggest the following (1 primary schooling broadly mitigates conflicts in Africa. However, in environments with high natural resource rents, it could ignite conflicts; (2 there is evidence, although not overwhelming, that secondary schooling potentially drives conflicts in Africa. There is also evidence that urbanization potentially drives conflicts in Africa. However, although secondary schooling and urbanization potentially drives conflicts, in environments where secondary schooling (urbanization is high, urbanization (secondary schooling mitigates conflicts; (3 there is no evidence of a strong direct positive impact of tertiary education on conflicts and conditioning on tertiary schooling, income inequality potentially drives conflicts in African states. However, in contexts where income inequality (tertiary schooling is high, tertiary schooling (inequality mitigates conflict. Two important policy implications follow from this study. First, in contexts where income inequality is high (for instance, in South Africa, governments should strive to foster tertiary education in order to reduce conflict. Second, where urbanization rates are high, they should foster both secondary and tertiary education. This study contributes to existing knowledge by clearly demonstrating the utility of distinguishing between different educational dimensions and the contexts wherein they matter for conflict mitigation in Africa.

  13. Formation mechanism of NDMA from ranitidine, trimethylamine, and other tertiary amines during chloramination: a computational study. (United States)

    Liu, Yong Dong; Selbes, Meric; Zeng, Chengchu; Zhong, Rugang; Karanfil, Tanju


    Chloramination of drinking waters has been associated with N-nitrosodimethylamine (NDMA) formation as a disinfection byproduct. NDMA is classified as a probable carcinogen and thus its formation during chloramination has recently become the focus of considerable research interest. In this study, the formation mechanisms of NDMA from ranitidine and trimethylamine (TMA), as models of tertiary amines, during chloramination were investigated by using density functional theory (DFT). A new four-step formation pathway of NDMA was proposed involving nucleophilic substitution by chloramine, oxidation, and dehydration followed by nitrosation. The results suggested that nitrosation reaction is the rate-limiting step and determines the NDMA yield for tertiary amines. When 45 other tertiary amines were examined, the proposed mechanism was found to be more applicable to aromatic tertiary amines, and there may be still some additional factors or pathways that need to be considered for aliphatic tertiary amines. The heterolytic ONN(Me)2-R(+) bond dissociation energy to release NDMA and carbocation R(+) was found to be a criterion for evaluating the reactivity of aromatic tertiary amines. A structure-activity study indicates that tertiary amines with benzyl, aromatic heterocyclic ring, and diene-substituted methenyl adjacent to the DMA moiety are potentially significant NDMA precursors. The findings of this study are helpful for understanding NDMA formation mechanism and predicting NDMA yield of a precursor.

    This article studies the contemporary expression of transitional justice, a field of practice through which global governance is exercised. It argues that transitional justice is being normalised, given the normative and empirical de-legitimisation of its premise of exceptionalism. The article...... theorises exceptionalism and normalcy in transitional justice and identifies three macro-level causes of normalisation: the legalisation, internationalisation, and professionalization of the field. This argument is illustrated by a study of Uganda’s trajectory of transitional justice since 1986.

    Full Text Available BACKGROUND Anaemia causes a reduction in the oxygen carrying capacity of the blood resulting in tissue hypoxia. Cardiac output at rest is not usually increased in most chronic anaemia until haemoglobin levels fall below 7 g/dL, but abnormal rise in output with exercise may occur with levels as high as 10 g/dL. The increase in cardiac output has been observed to correlate well with the degree of anaemia. Other compensatory mechanisms to chronic anaemia available to the body include decreased circulation time and increased tissue oxygen uptake. The latter is facilitated by a shift to the right of the oxygen haemoglobin dissociation curve. Cardiomegaly may also be as a result of the increased workload on the heart from the increased viscosity of blood in anaemia patients. Anaemia in the elderly is an extremely common problem that is associated with increased mortality and poorer health-related quality of life, regardless of the underlying cause of the low haemoglobin. A study of anaemia in elderly patients found a wide variation in prevalence, ranging from 2.9% to 61% in men and 3.3% to 41% in women. Higher rates were found in hospitalised patients than in community dwellers. It is easy to overlook anaemia in the elderly, since such symptoms as fatigue, weakness, or shortness of breath may be attributed to the ageing process itself. Our objective is to show the prevalence of anaemia even in a tertiary health care centre. METHODS One hundred patients were identified who were admitted in the Department of Medicine, Deccan College of Medical Sciences. Among the 100 patients, 38 were male and 62 were female. The study was conducted from Jan 2014 To Jan 2015. Patients having haemoglobin less than 10 g% in the medical wards were enrolled in the study. RESULTS Among the 100 patients, 38 were male and 62 were female. The average haemoglobin was 6.4 g%, the lowest being 2.8 g%. Peripheral blood smear showed hypochromic picture in 58, macrocytic picture in

  16. Kinematics and age of Early Tertiary trench parallel volcano-tectonic lineaments in southern Mexico: Tectonic implications (United States)

    Martini, M.; Ferrari, L.; Lopez Martinez, M.; Cerca Martinez, M.; Serrano Duran, L.


    We present new geological, structural, and geochronological data that constrain the timing and geometry of Early Tertiary strike slip deformation in southwestern Mexico and its relation with the concurrent magmatic activity. Geologic mapping in Guerrero and Michoacan States documented two regional WNW trending volcano-tectonic lineaments sub parallel to the present trench. The southernmost lineament runs for ~140 km from San Miguel Totolapan area (NW Guerrero) to Sanchiqueo (SE Michoacan), and passes through Ciudad Altamirano. Its southeastern part is marked by the alignment of at least eleven silicic to intermediate major domes as well as by the course of the Balsas River. The northwestern part of the lineament is characterized by ductile left lateral shear zones in Early Tertiary plutonic rocks observed in the Rio Chiquito valley. Domes near Ciudad Altamirano are unaffected by ductile shearing and yielded a ~42 Ma 40Ar/39Ar age, setting a minimum age for this deformation. The northern volcano-tectonic lineament runs for ~190 km between the areas of Huitzuco in northern Guerrero and the southern part of the Tzitzio fold in eastern Michoacan. The Huautla, Tilzapotla, Taxco, La Goleta and Nanchititla silicic centers (all in the range 37-34 Ma) are emplaced along this lineament, which continues to the WNW trough a mafic dike swarm exposed north of Tiquicheo (37-35 Ma) and the Purungueo subvolcanic body (~42 Ma). These rocks, unaffected by ductile shearing, give a minimum age of deformation similar to the southern Totolapan-Sanquicheo lineament. Post ~42 Ma deformation is essentially brittle and is characterized by several left lateral and right lateral transcurrent faults with typical Riedel patterns. Other trench-parallel left lateral shear zones active in pre-Oligocene times were recently reported in western Oaxaca. The recognizing of Early Tertiary trench-parallel and left-lateral ductile shearing in internal areas of southern Mexico suggest a field of widely

    Drago, Francesco; Ciccarese, Giulia; Tomasini, Carlo F; Calamaro, Paola; Boggio, Maurizio; Rebora, Alfredo; Parodi, Aurora


    We describe herein a woman who developed subcutaneous gummas in her trochanteric regions, bilaterally, although she had been treated for syphilis two decades earlier. Evidence of Treponema pallidum latent late infection was the presence of IgG antibodies against T. pallidum and the positive non-treponemal and treponemal tests. Moreover, immunohistochemical staining for T. pallidum detected some spirochetes close to the atrophic adipocytes allowing the diagnosis of lypo-atrophic panniculitis tertiary syphilis. This is the first case of tertiary syphilis presenting as panniculitis in an immunocompetent patient, demonstrating that subcutaneous fat may be another organ infected in tertiary syphilis.

  18. Fungal Profile of Vulvovaginal Candidiasis in a Tertiary Care Hospital. (United States)

    Kalaiarasan, Krishnapriya; Singh, Rakesh; Chaturvedula, Latha


    Vulvovaginal Candidiasis (VVC) is a common medical health problem of adult women. It is most commonly caused by Candida albicans . But there is a change in fungal profile. Sabouraud's Dextrose Agar (SDA) is the most common culture medium used where mixed fungal infection may be missed. It can be detected easily by using chromogenic culture medium. To know the fungal profile of vulvovaginal candidiasis using Candida CHROMagar and antifungal susceptibility pattern in patients attending tertiary care hospital. Culture confirmed cases of VVC presented at Department of Obstetrics and Gynaecology of Jawaharlal Institute of Postgraduate Medical Education and Research (JIPMER), Puducherry, India, from July 2015 to December 2015 were included in the cross-sectional study. Two high vaginal swabs were collected and inoculated on SDA and Candida CHROMagar (Hi-Media, Mumbai, India). After overnight incubation the colonies were counted and colour of the colonies were recorded from Candida CHROMagar. Candida spp. were identified by sugar fermentation and assimilation tests and other conventional tests. Antifungal susceptibility tests were performed by the disc diffusion method using fluconazole (25 μg) and voriconazole (1μg) as per the Clinical and Laboratory Standards Institute (CLSI - M44-A2) guidelines. A total of 50 culture confirmed (23.7%) cases were detected from 211 clinically suspected VVC cases. Candida glabrata (45.1%) was the most common isolate, followed by Candida tropicalis (23.5%) , Candida albicans (17.6%) , Candida krusei (9.8%) and Candida parapsilosis (3.9%) . One mixed infection of C. glabrata and C. albicans was identified on Candida CHROMagar. Mixed fungal infection was observed in 2% of positive culture and 0.5% of VVC cases. The antifungal susceptibility testing revealed that 15.7% and 9.8% isolates of Candida spp. were resistant and Susceptible Dose Dependent (S-DD) respectively to fluconazole. The increase resistant against fluconazole was because of

  19. Ethyl tertiary-butyl ether: a toxicological review. (United States)

    McGregor, Douglas


    A number of oxygenated compounds (oxygenates) are available for use in gasoline to reduce vehicle exhaust emissions, reduce the aromatic compound content, and avoid the use of organo-lead compounds, while maintaining high octane numbers. Ethyl tertiary-butyl ether (ETBE) is one such compound. The current use of ETBE in gasoline or petrol is modest but increasing, with consequently similar trends in the potential for human exposure. Inhalation is the most likely mode of exposure, with about 30% of inhaled ETBE being retained by the lungs and distributed around the body. Following cessation of exposure, the blood concentration of ETBE falls rapidly, largely as a result of its metabolism to tertiary-butyl alcohol (TBA) and acetaldehyde. TBA may be further metabolized, first to 2-methyl-1,2-propanediol and then to 2-hydroxyisobutyrate, the two dominant metabolites found in urine of volunteers and rats. The rapid oxidation of acetaldehyde suggests that its blood concentration is unlikely to rise above normal as a result of human exposure to sources of ETBE. Single-dose toxicity tests show that ETBE has low toxicity and is essentially nonirritant to eyes and skin; it did not cause sensitization in a maximization test in guinea pigs. Neurological effects have been observed only at very high exposure concentrations. There is evidence for an effect of ETBE on the kidney of rats. Increases in kidney weight were seen in both sexes, but protein droplet accumulation (with alpha(2u)-globulin involvement) and sustained increases in cell proliferation occurred only in males. In liver, centrilobular necrosis was induced in mice, but not rats, after exposure by inhalation, although this lesion was reported in some rats exposed to very high oral doses of ETBE. The proportion of liver cells engaged in S-phase DNA synthesis was increased in mice of both sexes exposed by inhalation. ETBE has no specific effects on reproduction, development, or genetic material. Carcinogenicity studies

  2. Cosmological phase transitions

    International Nuclear Information System (INIS)

    Kolb, E.W.


    If the universe stated from conditions of high temperature and density, there should have been a series of phase transitions associated with spontaneous symmetry breaking. The cosmological phase transitions could have observable consequences in the present Universe. Some of the consequences including the formation of topological defects and cosmological inflation are reviewed here. One of the most important tools in building particle physics models is the use of spontaneous symmetry breaking (SSB). The proposal that there are underlying symmetries of nature that are not manifest in the vacuum is a crucial link in the unification of forces. Of particular interest for cosmology is the expectation that are the high temperatures of the big bang symmetries broken today will be restored, and that there are phase transitions to the broken state. The possibility that topological defects will be produced in the transition is the subject of this section. The possibility that the Universe will undergo inflation in a phase transition will be the subject of the next section. Before discussing the creation of topological defects in the phase transition, some general aspects of high-temperature restoration of symmetry and the development of the phase transition will be reviewed. 29 references, 1 figure, 1 table

  4. The tertiary origin of the allosteric activation of E. coli glucosamine-6-phosphate deaminase studied by sol-gel nanoencapsulation of its T conformer.

    Directory of Open Access Journals (Sweden)

    Sergio Zonszein

    Full Text Available The role of tertiary conformational changes associated to ligand binding was explored using the allosteric enzyme glucosamine-6-phosphate (GlcN6P deaminase from Escherichia coli (EcGNPDA as an experimental model. This is an enzyme of amino sugar catabolism that deaminates GlcN6P, giving fructose 6-phosphate and ammonia, and is allosterically activated by N-acetylglucosamine 6-phosphate (GlcNAc6P. We resorted to the nanoencapsulation of this enzyme in wet silica sol-gels for studying the role of intrasubunit local mobility in its allosteric activation under the suppression of quaternary transition. The gel-trapped enzyme lost its characteristic homotropic cooperativity while keeping its catalytic properties and the allosteric activation by GlcNAc6P. The nanoencapsulation keeps the enzyme in the T quaternary conformation, making possible the study of its allosteric activation under a condition that is not possible to attain in a soluble phase. The involved local transition was slowed down by nanoencapsulation, thus easing the fluorometric analysis of its relaxation kinetics, which revealed an induced-fit mechanism. The absence of cooperativity produced allosterically activated transitory states displaying velocity against substrate concentration curves with apparent negative cooperativity, due to the simultaneous presence of subunits with different substrate affinities. Reaction kinetics experiments performed at different tertiary conformational relaxation times also reveal the sequential nature of the allosteric activation. We assumed as a minimal model the existence of two tertiary states, t and r, of low and high affinity, respectively, for the substrate and the activator. By fitting the velocity-substrate curves as a linear combination of two hyperbolic functions with Kt and Kr as KM values, we obtained comparable values to those reported for the quaternary conformers in solution fitted to MWC model. These results are discussed in the

  5. Milestoning with transition memory (United States)

    Hawk, Alexander T.; Makarov, Dmitrii E.


    Milestoning is a method used to calculate the kinetics and thermodynamics of molecular processes occurring on time scales that are not accessible to brute force molecular dynamics (MD). In milestoning, the conformation space of the system is sectioned by hypersurfaces (milestones), an ensemble of trajectories is initialized on each milestone, and MD simulations are performed to calculate transitions between milestones. The transition probabilities and transition time distributions are then used to model the dynamics of the system with a Markov renewal process, wherein a long trajectory of the system is approximated as a succession of independent transitions between milestones. This approximation is justified if the transition probabilities and transition times are statistically independent. In practice, this amounts to a requirement that milestones are spaced such that trajectories lose position and velocity memory between subsequent transitions. Unfortunately, limiting the number of milestones limits both the resolution at which a system's properties can be analyzed, and the computational speedup achieved by the method. We propose a generalized milestoning procedure, milestoning with transition memory (MTM), which accounts for memory of previous transitions made by the system. When a reaction coordinate is used to define the milestones, the MTM procedure can be carried out at no significant additional expense as compared to conventional milestoning. To test MTM, we have applied its version that allows for the memory of the previous step to the toy model of a polymer chain undergoing Langevin dynamics in solution. We have computed the mean first passage time for the chain to attain a cyclic conformation and found that the number of milestones that can be used, without incurring significant errors in the first passage time is at least 8 times that permitted by conventional milestoning. We further demonstrate that, unlike conventional milestoning, MTM permits

    Many elements transform from a high temperature bcc phase to a more dense packed temperature phase. The great majority of these transitions are of 1st order, displacive and reconstructive. The lattice potentials which govern these martensitic transitions can be probed by inelastic neutron scattering, thereby answering fundamental questions like : Will the transition be announced by dynamical or static fluctuations? What are the trajectories for the displacements needed for the transformation? Does the vibrational entropy stabilize the high temperature phase?

    Full Text Available Irrational antibiotic consumption, especially in the case when there is no appropriate indication for its usage, may be one of the most crucial global issues for public health care, leading to bacterial resistance and the increase of indirect medical expenses. According to the report of the European program for the monitoring of the antibiotic consumption, Serbia is on the fifth place among the countries which are not members of EU. The goal of this work is the evaluation of antibiotic consumption in the Clinical Centre Niš, from 2007 to 2013, with the focus on the monitoring of the cephalosporins utilization, as they are one of the most prescribed groups of antibiotics in the tertiary health care. The utilization of antibiotics in the Clinical Center Niš in the observed period was obtained from the computerized database of the Department of Pharmacotherapy and expressed as defined daily dose (DDD per 100 bed/days (DBD. Our results showed that there was an increase in antibiotic use of the whole group of cephalosporins and penicillin as well as a reduction of quinolones consumption within the observed period. Our analysis showed that ceftriaxone was the most frequently prescribed cephalosporin, followed by cefuroxime. Although antibiotic therapy and prophylaxis in our hospital are in keeping with the recommended guidelines, the obtained results may suggest that cephalosporin consumption, and especially ceftriaxone consumption is higher than in other European countries.

    Abrams, Elissa M; Becker, Allan B


    Oral food challenges are the clinical standard for diagnosis of food allergy. Little data exist on predictors of oral challenge failure and reaction severity. A retrospective chart review was done on all pediatric patients who had oral food challenges in a tertiary care pediatric allergy clinic from 2008 to 2010. 313 oral challenges were performed, of which the majority were to peanut (105), egg (71), milk (41) and tree nuts (29). There were 104 (33%) oral challenge failures. Children were more likely to fail an oral challenge if they were older (P = .04), had asthma (P = .001) or had atopic dermatitis (P = .03). Risk of challenge failure was significantly different between food allergens, with more failures noted for peanut than for tree nuts, milk or egg (P = .001). Among challenge failures, 19% met criteria for anaphylaxis. Significantly more tree nut and peanut challenges met criteria for anaphylaxis than milk or egg (P Skin test size and specific IgE level were significantly higher in those who failed oral challenges (P < .001). The highest rate of challenge failure and severity of failure was to cashew, with 63% of cashew challenges reacting, of which 80% met clinical criteria for anaphylaxis. The risk of challenge failure differed with type of food studied, with peanut and tree nut having a higher risk of challenge failure and anaphylaxis. Cashew in particular carried a high risk and caution must be exercised when performing these types of oral challenges in children.

  12. Factors Hindering the Integration of CALL in a Tertiary Institution

    Directory of Open Access Journals (Sweden)

    Izaham Shah Ismail


    Full Text Available The field of Computer Assisted Language Learning (CALL is a field that is constantly evolving as it is very much dependent on the advancement of computer technologies. With new technologies being invented almost every day, experts in the field are looking for ways to apply these new technologies in the language classroom. Despite that, teachers are said to be slow at adopting technology in their classrooms and language teachers, whether at schools or tertiary institutions, are no exception. This study attempts to investigate the factors that hinder ESL instructors at an institution of higher learning from integrating CALL in their lessons. Interviews were conducted with five ESL instructors and results revealed that factors which hinder them from integrating CALL in their teaching are universal factors such as knowledge in technology and pedagogy, computer facilities and resources, absence of exemplary integration of CALL, personal beliefs on language teaching, views on the role of a computers as teacher, and evaluation of learning outcomes.

    We assessed job satisfaction among anesthesiologists at a tertiary hospital in Nigeria and identified elements of job stress and dissatisfaction. A cross-sectional study design was employed; a structured self-administered questionnaire was distributed, which focused on sociodemographic data, rating of job satisfaction, identification of stressors, and work relationships. Out of 55 questionnaires distributed, 46 (83.6%) completed questionnaires were returned. Overall, 27 (58.7%) of the anesthesiologists were satisfied with their job. While 8.7% were very satisfied (grade 5), 6.5% were very dissatisfied (grade 1) with their job. The stressors identified by the respondents were time pressures, long working hours with complaints of insufficient sleep, and employment status. Among the respondents, the medical officers were the most discontented (9 out of 12, 75%), followed by senior registrars (5 out of 9, 56%). A high percentage of participants (54.1%) declared that the one change if implemented that would enhance their job satisfaction was having a definite closing time. Our results showed that despite the demanding nature of anesthesiology as a specialty, many anesthesiologists were contented with their job.

Patients and Methods: All patients with cutaneous drug eruptions seen at the Dermatology Department of Mayo Hospital, Lahore, over 6 months were enrolled and the pattern of drug eruptions like urticaria, angioedema, fixed drug eruption, maculopapular rash, erythema multiforme, Stevens-Johnson syndrome and toxic epidermal necrolysis etc. were recorded, along with drugs that caused it. Results:A total of 160 patients (86 males, 74 females) were included in the study. Mean age of patients was 30.7+-15.4 years. Major eruptions were fixed drug eruption (21.3%) followed by urticaria without angioedema (10%), maculopapular rash (9.3%), lichenoid drug eruption (8.7%), acneiform drug eruption (7.5%), Stevens-Johnson syndrome (6.9%), vesiculobullous eruption (5.6%), erythema multiforme and eczematous eruption (5% each). Common drugs causing eruptions were sulfonamides (16.3%), followed by NSAIDs (14.4%), herbal and homeopathic medications (12.5%), penicillins (9.3%), tetracyclines (8.7%), antituberculous drugs, cephalosporins and antiepileptics (6.3% each). Conclusion: Fixed drug eruption and urticaria without angioedema were commonest eruptions while, sulfonamides and NSAIDs were the major causative drugs. Policy message: Reporting of adverse drug reactions is not done in Pakistan and needs to be done in each hospital. (author)

  15. Experience of Oesophageal atresia management in a tertiary Bangladeshi hospital. (United States)

    Islam, Md Kabirul


    Background and aim: This study has been conducted to determine the clinical presentations and surgical outcome of patients with OA admitted in a tertiary level hospital in Bangladesh. A prospective analysis was conducted for 32 patients with confirmed OA between July 2007 and June 2015. Of them surgical correction was done in 25 cases. The other 7, in whom surgery could not be done, were excluded from the study. Of the 25 cases, that had been operated, 15 were full term and 52% were more than 48 hours old. Type-C OA with TOF was the commonest type (96%). 24 cases were operated through Right Thoracotomy. Of them 52% were done by Single Lung (left) ventilation. 'Division of the fistula' with 'end to end anastomosis' was done in all of them. Only 1 patient had a Gastric pull up surgery. Of the 25 cases, 16 survived (64%). In follow up all the patients were found thriving and showed no problem in swallowing. Our study which shows 64% survival is a great achievement for us but not satisfactory in international standard. However, the experience and encouragement that we are gathering, will guide us to achieve better result in near future.

    After having recalled objectives defined within the Building Plan of the Grenelle de l'Environnement, this guide aims at providing local communities with a relatively precise view of the energy consumption of buildings (residential and office buildings) on their territory in order to define actions to be undertaken, with keys to integrate these actions into a regional energy planning, and with tools for the follow-up of equipment, techniques, and tax or regulatory arrangements aimed at a better energy efficiency in order to be able to assess the impact of undertaken actions and to steer their implementation. Thus, the different parts of this guide describe how to perform an energy assessment in the residential-tertiary sector (indication of reference data, assessment of additional data), how to plan a regional energy renovation (definition of objectives, identification of associated needs, assessment of externalities), and how to perform a follow-up of energy efficiency (existing monitoring organisations and bodies, networking of actors and sharing of good practices, information sites)

  17. Open-Access Single Balloon Enteroscopy: A Tertiary Care Experience. (United States)

    Holman, Nathan; Wallace, Kristin; Moore, J Matthew; Brock, Andrew S


    To compare single balloon enteroscopy (SBE) between patients seen in consultation by a member of our gastroenterology team with those performed as open-access cases. Retrospective study of all patients who underwent SBE at a single tertiary care center from April 2008 to January 2012. Open- and closed-access procedures were compared in terms of diagnostic and therapeutic yield, adverse events, and procedural success. A total of 125 SBEs were performed on 125 patients. The mean age was 63.1 (53% men) years. In all, 43 procedures were performed open access and 82 after face-to-face consultation. Indications included anemia/gastrointestinal bleeding (110), abdominal pain (8), and other (7). Diagnostic yield for open- and closed-access procedures was 53% and 60%, respectively (P = 0.501) and therapeutic yield was 37% and 52%, respectively (P = 0.11). Overall technical success was 91% with no difference between the groups (P = 0.27). There were no major adverse events in either group. SBE can be performed as an open-access procedure without compromise to safety or diagnostic yield.

    Öztürk, Murat; Özek, Nuri; Yüksel, Yunus Emre


    Highlights: ► Production energy by burning of coals including high rate of ash and sulfur is harmful to environment. ► Energy production via coal gasification instead of burning is proposed for sustainable approach. ► We calculate exergy and environmental destruction factor of gasification of some tertiary coals. ► Sustainability index, improvement potential of gasification are evaluated for exergy-based approach. - Abstract: The utilization of coal to produce a syngas via gasification processes is becoming a sustainability option because of the availability and the economic relevance of this fossil source in the present world energy scenario. Reserves of coal are abundant and more geographically spread over the world than crude oil and natural gas. This paper focuses on sustainability of the process of coal gasification; where the synthesis gas may subsequently be used for the production of electricity, fuels and chemicals. The coal gasifier unit is one of the least efficient step in the whole coal gasification process and sustainability analysis of the coal gasifier alone can substantially contribute to the efficiency improvement of this process. In order to evaluate sustainability of the coal gasification process energy efficiency, exergy based efficiency, exergy destruction factor, environmental destruction factor, sustainability index and improvement potential are proposed in this paper.

  1. Wildfires and animal extinctions at the Cretaceous/Tertiary boundary (United States)

    Adair, Robert K.


    Persuasive models of the ejection of material at high velocities from the Chicxulub asteroid impact marking the Cretaceous/Tertiary boundary have led to the conclusion that upon return, that material, heated in passage through the upper atmosphere, generated a high level of infrared energy density over the Earth's surface. That radiant energy has been considered to be a direct source of universal wildfires, which were presumed to be a major cause of plant and animal species extinctions. The extinction of many animal species, especially the dinosaurs, has also been attributed to the immediate lethal effects of the radiation. I find that the absorption of the radiation by the atmosphere, by cloud formations, and by ejecta drifting in the lower atmosphere reduced the radiation at the surface to a level that cannot be expected to have generated universal fires. Although the reduced radiation will have likely caused severe injuries to many animals, such insults alone seem unlikely to have generated the overall species extinctions that have been deduced.

  2. The debate over the Cretaceous-Tertiary boundary (United States)

    Alvarez, W.; Asaro, F.; Alvarez, L. W.; Michel, H. V.


    Large-body impact on the Earth is a rare but indisputable geologic process. The impact rate is approximately known from objects discovered in Earth-crossing orbits and from the statistics of craters on the Earth's surface. Tektite and microtektite strewn fields constitute unmistakable ejecta deposits that can be due only to large-body impacts. The Cretaceous-Tertiary (K-T) boundary coincides with an unusually severe biological trauma, and this stratigraphic horizon is marked on a worldwide basis by anomalous concentrations of noble metals in chondritic proportions, mineral spherules with relict quench-crystallization textures, and mineral and rock grains showing shock deformation. These features are precisely compatible with an impact origin. Although only impact explains all the types of K-T boundary evidence, the story may not be as simple as once thought. The original hypothesis envisioned one large impact, triggering one great extinction. Newer evidence hints at various complications. Different challenges are faced by the occupants of each apex of a three-cornered argument over the K-T event. Proponents of a non-impact explanation must show that the evidence fits their preferred model better than it fits the impact scenario. Proponents of the single impact-single extinction view must explain away the complications. Proponents of a more complex impact crisis must develop a reasonable scenario which honors the new evidence.

    Septic thrombophlebitis of the portal vein or its branches, most often secondary to intra-abdominal infection is known as pylephlebitis. The frequency and the prognosis of this complication are unknown. The aim of this study was to determine the global and relative incidence of the most frequent intra-abdominal infections and the real prognosis of this disease. An observational retrospective study was conducted in a tertiary care hospital (University Hospital of Salamanca, Spain) from January 1999 to December 2008. A total of 7796 patients with intra-abdominal infection were evaluated, of whom 13 (0.6%) had been diagnosed with pylephlebitis. Diverticulitis was the most frequent underlying process, followed by biliary infection. Early mortality was 23%. Survivors had no recurrences, but one of them developed portal cavernomatosis. Pylephlebitis is a rare complication of intra-abdominal infection, with a high early mortality, but with a good prognosis for survivors.

  4. Seawater strontium isotopes at the Cretaceous-Tertiary boundary (United States)

    Macdougall, J. D.; Martin, E.


    Anomalously high values of Seawater Sr-87/Sr-86 near the Cretaceous-Tertiary (K-T) boundary have been reported. However, few of the data from the literature are from a single continuous section, and perhaps the most complete study of the boundary region, from a shallow marine limestone sequence in Alabama, showed elevated Sr-87/Sr-86 but no pronounced spike. Thus, in order to investigate the cause of the change in strontium isotopic composition, it is important to determine the exact nature and magnitude of the increase by studying in detail continuous sections through the boundary. If there is indeed a Sr isotope spike at the K-T boundary, it requires the addition of a large amount of radiogenic Sr to the oceans over a short time period, a phenomenon that may be linked to other large-scale environmental disturbances which occurred at that time. In order to address this question, a high-resolution strontium isotope study of foraminifera from three Deep Sea Drilling Project (DSDP) cores which recovered the K-T boundary section: Site 356 in the South Atlantic, Site 384 in the North Atlantic and Site 577 from the Shatsky Rise in the Pacific was initiated. The isotope measurements are being made on either single or small numbers of forams carefully picked and identified and in most cases examined by SEM before analysis. Because this work is not yet complete, conclusions drawn here must be viewed as tentative. They are briefly discussed.

    The terpenoid composition and class of Tertiary resins preserved within lignites of Cambay, Kutch and Cauvery Basins of India have been characterized using Pyrolysis-Gas Chromatography-Mass Spectrometry (Py-GC-MS) and Fourier Transform Infrared (FTIR) Spectroscopy. Major pyrolysis products include cadalene-based C{sub 15}-bicyclic sesquiterpenoids with some C{sub 30} and C{sub 31} bicadinanes and bicadinenes typical of Class II or dammar resin. The occurrence of these terpenoids in Early Eocene sediments may extend the first appearance of Dipterocarpaceae angiosperms, the predominant source of this resin class, back to the Early Eocene epoch in India. The same terpenoid biomarkers have been detected in many SE Asian oils reflecting a close source relationship with these resins. Strong CH{sub 3} (1377 cm{sup -} {sup 1}) and other CH{sub x} (3000-2800 and 1460-1450 cm{sup -} {sup 1}) aliphatic absorptions of much larger intensity than the aromatic C = C (1560-1650 cm{sup -} {sup 1}) absorption were detected in the Indian resins by FTIR Spectroscopy, confirming the quantitative significance of the terpenoid pyrolysates.

Considering that XP is a rare genetic disease, this description of our patient population will aid in early recognition and diagnosis. Retrospective and small number of patients. Genetic analyses were done for only 5 of the 21 patients.

  7. Tertiary Lymphoid Organs in Central Nervous System Autoimmunity

    Directory of Open Access Journals (Sweden)

    Meike Mitsdoerffer


    Full Text Available Multiple sclerosis (MS is an autoimmune disease characterized by chronic inflammation in the central nervous system (CNS, which results in permanent neuronal damage and substantial disability in patients. Autoreactive T cells are important drivers of the disease, however, the efficacy of B cell depleting therapies uncovered an essential role for B cells in disease pathogenesis. They can contribute to inflammatory processes via presentation of autoantigen, secretion of pro-inflammatory cytokines and production of pathogenic antibodies. Recently, B cell aggregates reminiscent of tertiary lymphoid organs (TLOs were discovered in the meninges of MS patients, leading to the hypothesis that differentiation and maturation of autopathogenic B and T cells may partly occur inside the CNS. Since these structures were associated with a more severe disease course, it is extremely important to gain insight into the mechanism of induction, their precise function and clinical significance. Mechanistic studies in patiens are limited. However, a few studies in the MS animal model experimental autoimmune encephalomyelitis (EAE recapitulate TLO formation in the CNS and provide new insight into CNS TLO features, formation and function. This review summarizes what we know so far about CNS TLOs in MS and what we have learned about them from EAE models. It also highlights the areas that are in need of further experimental work, as we are just beginning to understand and evaluate the phenomenon of CNS TLOs.

    Objective: To describe the results of laparoscopic procedures at a Urology - Nephrology tertiary care centre. Study Design: Case series / observational study. Place and Duration of Study: The Kidney Centre Postgraduate Training Institute, Karachi, from August 2007 to March 2012. Methodology: Medical records of all planned laparoscopic surgery conducted during the study period were reviewed. Those cases which to open surgery were excluded. All were performed by a single surgeon, initially as supervised and later independently. Data was maintained for demographic data, procedure details, length of hospital stay, and complications including conversion to open surgeries. Data was analyzed through SPSS 17.0. Results: There were 36 planned laparoscopic surgeries in the specified period. Out of 36 cases, 8 were converted to open surgery. Those who underwent laparoscopic surgery include two diagnostic procedures and renal cyst deroofing each, four ureterolithotomy, nineteen simple nephrectomy and one radical nephrectomy. So in total 28 cases were performed on 15 females and 13 males with mean age of 33.01 A +- 10.9 years. The mean operative time was 216 A +- 100 minutes and mean length of hospital stay was as 2.7 A +- 1.04 days. There were 10 complications in 28 cases, majority being Clavien Grade II including 7% (2/28) blood transfusion. Conclusion: There are technical challenges in learning laparoscopy for practicing urologists. Following some learning model in a systematic manner will help surmounting the technical challenges in learning laparoscopy. (author)

    Ribera, F.; Dorca, H.; Martinez, P.; Pina, J.; Otero, N.; Palau, J.; Solar, A.


    The Catalonian Potassic Basin is described as a thick regressive-sedimentary Tertiary basin that includes marine, evaporitic-transitional and continental facies, overlying by no-consolidated quaternary alluvial sediments. The intense underground mining activity used in the exploitation of salts with rich K contents in the CPC during the last century, has provoked some problems related to surface and groundwater contamination and the existence of subsidence areas. The objective of the hydrogeological studies in the CPC area are focused in the characterization of the Tertiary aquifer and the definition of their conceptual model of behaviour. The last challenge of the project is to determine the relationship between subsidence and hydrogeology in these salt bodies. (Author) 14 refs.

    Full Text Available We present the photometric study of an interesting target in the CoRoT exoplanet database: CoRoT 310266512. Its light curve shows primary, secondary and tertiary eclipses that suggests the presence of at least three celestial bodies. The primary and secondary eclipses have the same orbital period, 7.42 days, and the tertiary eclipse has an orbital period of 3.27 days. Two of the tertiary eclipses fall within a primary eclipse and a secondary eclipse. The properties of the light curve indicate the presence of two physically separated systems. The primary and secondary eclipses corresponds to a binary system (System I. The tertiary eclipses correspond to a star-planet system or a star-dwarf system (System II. Some parameters of these two systems are obtained from JKTEBOP [1] program.

  14. The development of the tertiary sector in the economy and the reduction in CO2 emissions

    International Nuclear Information System (INIS)

    Morvan, R.; Hubert, M.; Gregoire, P.; Lowezanin, Ch.


    The development of the tertiary sector appears to support sustainable development since it now accounts for almost two thirds of the national economy and is responsible for low CO 2 emission levels. Between 1980 and 1997, CO 2 emissions from the tertiary sector increased by 20 % compared with a 48 % rise in the sector value added. In terms of production, CO 2 levels in the tertiary sector are low, compared with 55 % for the secondary sector (industry). However, when trade between economic activities is taken into account, there is cause to qualify the assessment. This makes it possible to ascertain emissions from the point of view of satisfying final demand for products, and to identify direct and indirect emissions in each branch of activity. Thus, when emissions from certain industrial and agricultural activities are redistributed specifically to branches of activity in the tertiary sector, CO 2 emissions in this sector account for almost one-third of total emissions.

    Lu, Yuan-Qing; Shi, Jun


    Tertiary industry has been developed in recent years. And it is very important to find the factors influenced the energy-related carbon emissions in tertiary industry. A decomposition model of energy-related carbon emissions for China is set up by adopting logarithmic mean weight Divisia method based on the identity of carbon emissions. The model is adopted to analyze the influence of energy structure, energy efficiency, tertiary industry structure and economic output to energy-related carbon emissions in China from 2000 to 2009. Results show that the contribution rate of economic output and energy structure to energy-related carbon emissions increases year by year. Either is the contribution rate of energy efficiency or the tertiary industry restraining to energy-related carbon emissions. However, the restrain effect is weakening.

  17. Distinguishing between tertiary and secondary facilities: a case study of cardiac diagnostic-related groups (DRGs). (United States)

    Rouse, Paul; Arulambalam, Ajit; Correa, Ralph; Ullman, Cornelia


    To develop a classification of tertiary cardiac DRGs in order to investigate differences in tertiary/secondary product mix across New Zealand district health boards (DHBs). 67 DRGs from 85,442 cardiac cases were analysed using cost weights and patient comorbidity complexity levels, which were used as a proxy for complexity. The research found high variability of severity within some DRGs. 5 DHBs are the main providers of 27 DRGs which are high cost and identified as tertiary by several ADHB clinicians; the same 5 DHBs have on average higher severity by DRG than the other DHBs. NZ tertiary hospitals have a product mix of DRGs with higher complexity than secondary hospitals. Funding based on case weights needs to recognise the additional resource requirements for this higher complexity.

  18. Tertiary instability of zonal flows within the Wigner-Moyal formulation of drift turbulence (United States)

    Zhu, Hongxuan; Ruiz, D. E.; Dodin, I. Y.


    The stability of zonal flows (ZFs) is analyzed within the generalized-Hasegawa-Mima model. The necessary and sufficient condition for a ZF instability, which is also known as the tertiary instability, is identified. The qualitative physics behind the tertiary instability is explained using the recently developed Wigner-Moyal formulation and the corresponding wave kinetic equation (WKE) in the geometrical-optics (GO) limit. By analyzing the drifton phase space trajectories, we find that the corrections proposed in Ref. to the WKE are critical for capturing the spatial scales characteristic for the tertiary instability. That said, we also find that this instability itself cannot be adequately described within a GO formulation in principle. Using the Wigner-Moyal equations, which capture diffraction, we analytically derive the tertiary-instability growth rate and compare it with numerical simulations. The research was sponsored by the U.S. Department of Energy.

  1. Suppression of excess noise in Transition-Edge Sensors using magnetic field and geometry

    Ullom, J.N.; Doriese, W.B.; Hilton, G.C.; Beall, J.A.; Deiker, S.; Irwin, K.D.; Reintsema, C.D.; Vale, L.R.; Xu, Y.


    We report recent progress at NIST on Mo/Cu Transition-Edge Sensors (TESs). While the signal-band noise of our sensors agrees with theory, we observe excess high-frequency noise. We describe this noise and demonstrate that it can be strongly suppressed by a magnetic field perpendicular to the plane of the sensor. Both the excess noise and α=(T/R)(dR/dT) depend strongly on field so our results show that accurate comparisons between devices are only possible when the field is well known or constant. We also present results showing the noise performance of TES designs incorporating parallel and perpendicular normal metal bars, an array of normal metal islands, and in wedge-shaped devices. We demonstrate significant reduction of high-frequency noise with the perpendicular bar devices at the cost of reduced α. Both the bars and the magnetic field are useful noise reduction techniques for bolometers

  7. Slow-transit Constipation. (United States)

    Bharucha, Adil E.; Philips, Sidney F.


    Idiopathic slow-transit constipation is a clinical syndrome predominantly affecting women, characterized by intractable constipation and delayed colonic transit. This syndrome is attributed to disordered colonic motor function. The disorder spans a spectrum of variable severity, ranging from patients who have relatively mild delays in transit but are otherwise indistinguishable from irritable bowel syndrome to patients with colonic inertia or chronic megacolon. The diagnosis is made after excluding colonic obstruction, metabolic disorders (hypothyroidism, hypercalcemia), drug-induced constipation, and pelvic floor dysfunction (as discussed by Wald ). Most patients are treated with one or more pharmacologic agents, including dietary fiber supplementation, saline laxatives (milk of magnesia), osmotic agents (lactulose, sorbitol, and polyethylene glycol 3350), and stimulant laxatives (bisacodyl and glycerol). A subtotal colectomy is effective and occasionally is indicated for patients with medically refractory, severe slow-transit constipation, provided pelvic floor dysfunction has been excluded or treated.

  8. Superconductivity in transition metals. (United States)

    Slocombe, Daniel R; Kuznetsov, Vladimir L; Grochala, Wojciech; Williams, Robert J P; Edwards, Peter P


    A qualitative account of the occurrence and magnitude of superconductivity in the transition metals is presented, with a primary emphasis on elements of the first row. Correlations of the important parameters of the Bardeen-Cooper-Schrieffer theory of superconductivity are highlighted with respect to the number of d-shell electrons per atom of the transition elements. The relation between the systematics of superconductivity in the transition metals and the periodic table high-lights the importance of short-range or chemical bonding on the remarkable natural phenomenon of superconductivity in the chemical elements. A relationship between superconductivity and lattice instability appears naturally as a balance and competition between localized covalent bonding and so-called broken covalency, which favours d-electron delocalization and superconductivity. In this manner, the systematics of superconductivity and various other physical properties of the transition elements are related and unified. © 2015 The Author(s) Published by the Royal Society.

  9. Transition to turbulence

    International Nuclear Information System (INIS)

    Pomeau, Y.


    In this work it is reviewed a few known types of transition to turbulence, as the cascade of period doubling and the intermittent transition. This happens in dynamical systems with a few degrees of freedom, as modelled by the iteration of non linear maps. Then it is presented specific transitions for systems with many degrees of freedom. It is condidered first the occurence of a low frequency broadband noise in large cells at the onset of Rayleigh-Benard convection; then the transition by intermittent bursts in parallel flows. In this last case, one is concerned with localized and finite amplitude perturbations. Simple geometric arguments show that these fluctuations, when they are isolated and with a well definite relative speed, exist for a single value of the Reynolds number only [fr

    Due to the drastic decrease in artificial radioactivity levels from primary sources such as atmospheric fallout or industrial releases, radioactive storages constituted in the past within several environmental compartments act today as non negligible secondary sources. These delayed sources are particularly active during extreme weather or climatic events such as rainfalls or atmospheric deposits, floods, storms, etc...that may remove important mass, generate activity levels higher than the predicted ones from modeling based on mean transfer process, and produce in a couple of hours or days fluxes similar to those accrued over several month or years. Extreme aims at assessing the consequences on man and its environment of natural events that generate extreme radioactive stocks and/or fluxes within several environmental compartments (atmosphere, soils, rivers, coastal marine environment and deep sea areas).

    Silva Junior, Luiz F.; Quintiliano, Samir A.P.; Ferraz, Helena M.C.; Santos, Leonardo S.; Eberlin, Marcos N.


    The oxidation of tertiary homoallylic alcohols with thallium trinitrate (TTN) was investigated. The alcohols bearing an allylic methyl group lose a molecule of acetone via a fragmentation reaction that leads to isomeric secondary allylic alcohols as major products, together with their corresponding acetylated derivatives. On the other hand, treating analogous tertiary alcohols without the allylic methyl group with TTN gives indans, through a ring contraction reaction. (author)

  17. West Hackberry Tertiary Project. Annual report, September 3, 1997--September 2, 1998

    Energy Technology Data Exchange (ETDEWEB)

    Gillham, T.H.


    The following report is the Project Management Plan for the fifth year of the West Hackberry Tertiary Project. The West Hackberry Tertiary Project is one of four mid-term projects selected by the United States Department of Energy (DOE) as part of the DOE`s Class 1 Program for the development of advance recovery technologies in fluvial dominated deltaic reservoirs. The West Hackberry Tertiary Project is a field test of the idea that air injection can be combined with the Double Displacement Process to produce a low cost tertiary recovery process which is economic at current oil prices. The Double Displacement Process is the gas displacement of a water invaded oil column for the purpose of recovering tertiary oil by gravity drainage. The Double Displacement Process is based upon the concept that in fields such as West Hackberry waterdrive recoveries are typically 50%-60% of the original oil in place while gravity drainage recoveries average 80%-90% of the original oil in place. Therefore, by injecting a gas into a watered out reservoir, a gas cap will form an additional oil can be recovered due to gravity drainage. Although the Double Displacement Process has been shown to be successful in recovering tertiary oil in other fields, this project will be the first to utilize air injection in the Double Displacement Process. The use of air injection in this process combines the benefits of air`s low cost and universal accessibility with the potential for accelerated oil recovery due to the combustion process. If successful, this project will demonstrate that the use of air injection in the Double Displacement Process will result in an economically viable tertiary process in reservoirs where tertiary oil recovery is presently uneconomical.

  18. Positive effects of tertiary centres for amyotrophic lateral sclerosis on outcome and use of hospital facilities. (United States)

    Chiò, A; Bottacchi, E; Buffa, C; Mutani, R; Mora, G


    To evaluate the effects of tertiary centres for amyotrophic lateral sclerosis (ALS) on ALS outcome and the use of hospital facilities. The study was based on the data of an epidemiological, prospective, population-based register on ALS (Piemonte and Valle d'Aosta Register for amyotrophic lateral sclerosis, PARALS). The 221 patients recruited between 1995 and 1996 were prospectively followed up for outcome and use of hospital-based services. In all, 97 patients were followed up by tertiary ALS centres and 124 by general neurological clinics. Patients followed up by tertiary ALS centres were found to be 4 years younger and underwent percutaneous endoscopic gastronomy and non-invasive positive-pressure ventilation more often. Patients followed up by tertiary ALS centres were found to have a considerably longer median survival time (1080 v 775 days), even when stratifying by age, site of onset and respiratory function at diagnosis. In Cox multivariate analysis, attending a tertiary ALS centre was observed to be an independent positive prognostic factor. Moreover, patients attending a tertiary ALS centre were admitted to hospital less often (1.2 v 3.3) and were more frequently admitted for planned interventions. Conversely, patients followed up by general neurological clinics were more frequently admitted for acute events. Also, the hospital stay was considerably shorter for patients attending tertiary ALS centres (5.8 v 12.4 days). Improved survival was seen in patients with ALS attending tertiary ALS centres, independently from all other known prognostic factors, possibly through a better implementation of supportive treatments. Moreover, because of these centres, the hospitalisation rate was markedly reduced, thus offering a cost-effective service to patients with ALS and to the community as a whole.

  4. Facility transition instruction

    International Nuclear Information System (INIS)

    Morton, M.R.


    The Bechtel Hanford, Inc. facility transition instruction was initiated in response to the need for a common, streamlined process for facility transitions and to capture the knowledge and experience that has accumulated over the last few years. The instruction serves as an educational resource and defines the process for transitioning facilities to long-term surveillance and maintenance (S and M). Generally, these facilities do not have identified operations missions and must be transitioned from operational status to a safe and stable configuration for long-term S and M. The instruction can be applied to a wide range of facilities--from process canyon complexes like the Plutonium Uranium Extraction Facility or B Plant, to stand-alone, lower hazard facilities like the 242B/BL facility. The facility transition process is implemented (under the direction of the US Department of Energy, Richland Operations Office [RL] Assistant Manager-Environmental) by Bechtel Hanford, Inc. management, with input and interaction with the appropriate RL division and Hanford site contractors as noted in the instruction. The application of the steps identified herein and the early participation of all organizations involved are expected to provide a cost-effective, safe, and smooth transition from operational status to deactivation and S and M for a wide range of Hanford Site facilities

    We report the optical response characteristics of Al/Ti bilayer transition edge sensors (TESs), which are mainly comprised of Al/Ti bilayer thermometers and suspended SiN membranes for thermal isolation. The measurement was performed in a 3 He sorption refrigerator and the device's response to optical pulses was investigated using a pulsed laser source. Based on these measurements, we obtained the effective recovery time (τ eff ) of the devices at different biases and discussed the dependence of τ eff on the bias. The device with a 940 μm × 940 μm continuous suspended SiN membrane demonstrated a fast response speed with τ eff = 3.9 μs, which indicates a high temperature sensitivity (α = T/R · dR/dT = 326). The results also showed that the TES exhibits good linearity under optical pulses of variable widths. (interdisciplinary physics and related areas of science and technology)

  7. Binocular diplopia in a tertiary hospital: Aetiology, diagnosis and treatment. (United States)

    Merino, P; Fuentes, D; Gómez de Liaño, P; Ordóñez, M A


    To study the causes, diagnosis and treatment in a case series of binocular diplopia. A retrospective chart review was performed on patients seen in the Diplopia Unit of a tertiary centre during a one-year period. Diplopia was classified as: acute≤1 month since onset; subacute (1-6 months); and chronic (>6 months). Resolution of diplopia was classified as: spontaneous if it disappeared without treatment, partial if the course was intermittent, and non-spontaneous if treatment was required. It was considered a good outcome when diplopia disappeared completely (with or without treatment), or when diplopia was intermittent without significantly affecting the quality of life. A total of 60 cases were included. The mean age was 58.65 years (60% female). An acute or subacute presentation was observed in 60% of the patients. The mean onset of diplopia was 82.97 weeks. The most frequent aetiology was ischaemic (45%). The most frequent diagnosis was sixth nerve palsy (38.3%), followed by decompensated strabismus (30%). Neuroimaging showed structural lesions in 17.7% of the patients. There was a spontaneous resolution in 28.3% of the cases, and there was a good outcome with disappearance of the diplopia in 53.3% at the end of the study. The most frequent causes of binocular diplopia were cranial nerve palsies, especially the sixth cranial nerve, followed by decompensated strabismus. Structural lesions in imaging tests were more than expected. Only one third of patients had a spontaneous resolution, and half of them did not have a good outcome despite of treatment.

    Juliana Mika Kato

    Full Text Available Objective: to analyze the epidemiology, clinical features and survival rate of patients undergoing orbital exenteration (OE in a tertiary referral hospital. Methods : we conducted a retrospective study of all patients undergoing OE at the Hospital das Clínicas, FMUSP between January 2007 and December 2012. We collected data records related to gender, age, origin, length of stay, duration of the disease, other treatments related to the disease, number of procedures outside of the face related to the disease, follow-up and histological diagnosis. Results : we treated 37 patients in the study period. The average survival in one year was 70%, in two years, 66.1%, and 58.3% in three years. There was no significant difference in the one-year survival related to histological diagnosis (p=0.15, days of hospitalization (p=0.17, gender (p=0.43, origin (p=0.78, disease duration (p=0.27 or the number of operations for the tumor (p=0.31. Mortality was higher in elderly patients (p=0.02. The average years of life lost was 33.9 in patients under 60 years, 14.7 in patients in the 61-80 years range and 11.3 in patients over 80 years. Conclusion : the present series of cases is significant in terms of prevalence of orbital exenteration; on the other hand, it shows one of the lowest survival rates in the literature. This suggests an urgent need for improved health care conditions to prevent deforming, radical resections.

  9. Experience of vascular trauma in a tertiary care hospital

    International Nuclear Information System (INIS)

    Imtiaz, N.


    To highlight the presentation and management of various vascular injuries and their outcome. Thirty nine cases of vascular trauma were referred to vascular surgeon CMH Rawalpindi, in the above mentioned period. These cases were evaluated for mechanism of injury, age, gender and time of presentation. Out of these, only thirty cases were found suitable for surgical intervention. These thirty cases were evaluated for site of vascular injury, associated injuries, type of surgery performed and the outcome. Blunt trauma was the predominant cause of vascular injuries in our study 16/39 (41%). Fourteen cases (35.8%) had gun shot wounds. Only thirty patients (76.9 %) underwent various surgical procedures. Primary end to end anastomosis was possible in only 5/30 cases (16.6%) while reversed venous graft was used in 13/30 cases (43.3%). Wound infection occurred in 2/30(6.6%) cases out of which 1 case (3.3%) ultimately had an amputation. The time period between injury and surgical intervention ranged between 1 to 20 hours for most of the vascular injuries while delayed presentation in the form of traumatic arteriovenous fistula or pseudoaneurysm was between 48 hours to 3 months. There are reasonable numbers of vascular trauma cases being referred to a tertiary care hospital. Most of these cases reach us quite late due to unnecessary investigations, delayed referral and transportation. Early intervention and revascularization definitely reduces amputation and complication rate. All gunshot wounds not only require thorough surrounding soft tissue debridement but also liberal excision of traumatised vessel itself, resulting in interposition graft repair. (author)

  10. Attitudes Toward Cognitive Enhancer Use Among New Zealand Tertiary Students. (United States)

    Ram, Sanyogita Sanya; Hussainy, Safeera; Henning, Marcus; Stewart, Kay; Jensen, Maree; Russell, Bruce


    Cognitive enhancement is the use of prescription stimulant medicines by healthy individuals for nonmedical use in academic settings. Commonly used cognitive enhancers (CEs) include methylphenidate, amphetamines, and modafinil. To understand the motivation to use CEs, it is important to look beyond prevalence and explore the extent to which attitudes, beliefs, and intentions predict the decision to use CEs. The study aimed to investigate what factors explain the decision to use CEs among tertiary students in New Zealand, using the Theory of Planned Behaviour (TPB). Students from the Schools of Pharmacy, Nursing, Medicine, Law, and Accounting at a university in New Zealand were invited to complete a paper-based questionnaire. The questionnaire elicited students' attitudes, subjective norms, and perceived control toward illicit use of CEs using TPB. An exploratory factor analysis was conducted. Response rate was 88.6% (442/499). Students who perceived CE use to be socially and ethically acceptable were more likely to use CEs (odds ratio, OR: 1.56, 95% confidence interval, 95% CI: 1.153-2.105, p = 0.004). Students who were concerned about the health impact of CE use were less likely to use CEs (OR: 0.54, 95% CI: 0.492-0.826, p = 0.001). Students who believed that CE use was approved were more likely to use them (OR: 1.648, CI: 1.193-2.278, p = 0.002). This research supports the notion that the decision to use CEs is not just an autonomous choice that occurs in isolation. Attitudes on the ethical and social acceptability of CE use were more likely to drive the decision to use CEs. The study provides the impetus for an integrative discussion by health care professionals and academics on the impact of attitudes, social norms, and advocates on the decision to use CEs.

    Full Text Available BACKGROUND Cancer is one of the leading cause of death both in developed and developing countries. In India, it accounts for 0.3 million deaths per year. Cancers of lung, GIT and oral cancers dominated among men while breast, cervix, ovary and oral cavity were commonest cancer seen in women. Among the gastrointestinal cancers, cancers of the oesophagus, stomach, colon, rectum and liver cancers were commonest. The aim of the study is to evaluate the incidence of the various GIT cancers in a tertiary hospital of Coastal Andhra when compared to other studies. MATERIALS AND METHODS In this retrospective study, a total of 509 health records of patients affected by cancers were studied and relevant details noted. RESULTS A total of 509 cancer cases were reported in this period of 18 months (January 2016 - June 2017 of which 85 cases (16.3% were of Gastrointestinal (GIT cancers. The age group between 40 and 60 recorded the maximum incidence of 47 cancers (55.1%. The incidence of gastrointestinal cancers were significantly higher in the men (56 cases (65.8% than the women (29 cases (34.11%. The commonest site of GIT cancers was the colorectal region (30 cases (35.7%. The most common type of cancer seen was adenocarcinoma seen in 73 cases (85.8%. CONCLUSION Public education and awareness for the warning symptoms should be increased to prevent reduction of the life span and health caused by the gastrointestinal cancers with intense awareness drive using various means including social media undertaken to educate the public regarding the warning symptoms and screening of such group for GIT cancers.

  13. Surveillance of antimicrobial resistance at a tertiary hospital in Tanzania

    Mashurano Marcellina


    Full Text Available Abstract Background Antimicrobial resistance is particularly harmful to infectious disease management in low-income countries since expensive second-line drugs are not readily available. The objective of this study was to implement and evaluate a computerized system for surveillance of antimicrobial resistance at a tertiary hospital in Tanzania. Methods A computerized surveillance system for antimicrobial susceptibility (WHONET was implemented at the national referral hospital in Tanzania in 1998. The antimicrobial susceptibilities of all clinical bacterial isolates received during an 18 months' period were recorded and analyzed. Results The surveillance system was successfully implemented at the hospital. This activity increased the focus on antimicrobial resistance issues and on laboratory quality assurance issues. The study identified specific nosocomial problems in the hospital and led to the initiation of other prospective studies on prevalence and antimicrobial susceptibility of bacterial infections. Furthermore, the study provided useful data on antimicrobial patterns in bacterial isolates from the hospital. Gram-negative bacteria displayed high rates of resistance to common inexpensive antibiotics such as ampicillin, tetracycline and trimethoprim-sulfamethoxazole, leaving fluoroquinolones as the only reliable oral drugs against common Gram-negative bacilli. Gentamicin and third generation cephalosporins remain useful for parenteral therapy. Conclusion The surveillance system is a low-cost tool to generate valuable information on antimicrobial resistance, which can be used to prepare locally applicable recommendations on antimicrobial use. The system pinpoints relevant nosocomial problems and can be used to efficiently plan further research. The surveillance system also functions as a quality assurance tool, bringing attention to methodological issues in identification and susceptibility testing.

  14. Carcinogenicity of methyl-tertiary butyl ether in gasoline. (United States)

    Mehlman, Myron A


    Methyl tertiary butyl ether (MTBE) was added to gasoline on a nationwide scale in 1992 without prior testing of adverse, toxic, or carcinogenic effects. Since that time, numerous reports have appeared describing adverse health effects of individuals exposed to MTBE, both from inhalation of fumes in the workplace and while pumping gasoline. Leakage of MTBE, a highly water-soluble compound, from underground storage tanks has led to contamination of the water supply in many areas of the United States. Legislation has been passed by many states to prohibit the addition of MTBE to gasoline. The addition of MTBE to gasoline has not accomplished its stated goal of decreasing air pollution, and it has posed serious health risks to a large portion of the population, particularly the elderly and those with respiratory problems, asthma, and skin sensitivity. Reports of animal studies of carcinogenicity of MTBE began to appear in the 1990s, prior to the widespread introduction of MTBE into gasoline. These reports were largely ignored. In ensuing years, further studies have shown that MTBE causes various types of malignant tumors in mice and rats. The National Toxicology Program (NTP) Board of Scientific Counselors' Report on Carcinogens Subcommittee met in December 1998 to consider listing MTBE as "reasonably anticipated to be a human carcinogen." In spite of recommendations from Dr. Bailer, the primary reviewer, and other scientists on the committee, the motion to list MTBE in the report was defeated by a six to five vote, with one abstention. On the basis of animal studies, it is widely accepted that if a chemical is carcinogenic in appropriate laboratory animal test systems, it must be treated as though it were carcinogenic in humans. In the face of compelling evidence, NTP Committee members who voted not to list MTBE as "reasonably anticipated to be a human carcinogen" did a disservice to the general public; this action may cause needless exposure of many to health risks

  15. Mainstreaming of Climate Change into the Ghanaian Tertiary Educational System (United States)

    Nyarko, B. K.


    The impact of Climate Change has a far-reaching implication for economies and people living in the fragile Regions of Africa analysts project that by 2020, between 75 million and 250 million people will be exposed various forms of Climate Change Stresses. Education as a key strategy identified under Agenda 21 has been incorporated into the efforts of various educational institutions as a means of mitigating climate change and enhancing sustainability. Climate Change education offers many opportunities and benefits for educators, researchers, learners, and for wider society, but there are also many challenges, which can hinder the successful mainstreaming of climate change education. The study aims at understanding barriers for Climate Change Education in selected tertiary institutions in Ghana. The study was conducted among Geoscience Departments of the 7 main public universities of Ghana. The transcript analysis identified issues that hinders the mainstreaming of Climate Change, these includes existing levels of knowledge and understanding of the concept of climate change, appreciating the threshold concepts, ineffective teaching of Climate Change and some Departments are slow in embracing Climate Change as a discipline. Hence to develop strategies to mainstream climate change education it is important to recognise that increasing the efficiency and delivery of Climate Change education requires greater attention and coordination of activities and updating the educators knowledge and skill's. Various Ministries should be challenged to develop and integrate climate change into education policies. In the design of curriculum, there is a need to integrate Climate Change Education into curricula without compromising already overstretched programmes of study. There is a need to encourage and enhance innovative teaching approaches such as Problem-based learning (PBL) is an approach that challenges students to learn through engagement in a real problem.

    Full Text Available Abstract One of the challenges facing result processing in Nigerian tertiary institutions is the problem of insecurity. Untraceable changes are made to students result and this result to various disasters such as innocent people losing their jobs since their innocence cannot be proven. Biometric based systems operate on behavioral and physiological biometric data to identify a person and grant required access to a user. Physiological characteristics such as fingerprint remains unchanged throughout an individuals life time and thus it can serve as a viable means of identifying and authenticating users who are to access a system. In this study fingerprint biometric based result processing software is developed to ensure that users are well authenticated and are made to see only what they are pre-configured to see and work with. The fingerprint authentication system was developed using visual Staff fingerprints were enrolled into the system to form a biometric template which the system validates against at every login attempt on the result processing software. The digital personal one touch ID sdk and other libraries were used in developing the authentication system. The result processing software also ensures that all write transactions to the database are confirmed and identified by forcing another biometric authentication at the point of making a write request to the web server and associated database. This ensures that the exact person initiating the transaction was the same user who logged in to the application. The users identified at login and various confirmation milestones set for write transactions are logged into a table for future reference and audit trail. Conclusively the developed system has helped to eradicate the problem of user impersonation by ensuring only authorized users are made to access the software and in-turn participate in result processing activities.

    Sivaranjini, R; Jaisankar, Tj; Thappa, Devinder Mohan; Kumari, Rashmi; Chandrasekhar, Laxmisha; Malathi, M; Parija, Sc; Habeebullah, S


    Vaginal discharge is one of the common reasons for gynecological consultation. Many of the causes of vaginitis have a disturbed vaginal microbial ecosystem associated with them. Effective treatment of vaginal discharge requires that the etiologic diagnosis be established and identifying the same offers a precious input to syndromic management and provides an additional strategy for human immunodeficiency virus prevention. The present study was thus carried out to determine the various causes of vaginal discharge in a tertiary care setting. A total of 400 women presenting with vaginal discharge of age between 20 and 50 years, irrespective of marital status were included in this study and women who had used antibiotics or vaginal medication in the previous 14 days and pregnant women were excluded. Of the 400 women with vaginal discharge studied, a diagnosis was established in 303 women. Infectious causes of vaginal discharge were observed in 207 (51.75%) women. Among them, bacterial vaginosis was the most common cause seen in 105 (26.25%) women. The other infections observed were candidiasis alone (61, 15.25%), trichomoniasis alone (12, 3%), mixed infections (22, 5.5%) and mucopurulent cervicitis (7 of the 130 cases looked for, 8.46%). Among the non-infectious causes, 72 (18%) women had physiological vaginal discharge and 13 (3.3%) women had cervical in situ cancers/carcinoma cervix. The pattern of infectious causes of vaginal discharge observed in our study was comparable with the other studies in India. Our study emphasizes the need for including Papanicolaou smear in the algorithm for evaluation of vaginal discharge, as it helps establish the etiology of vaginal discharge reliably and provides a valuable opportunity to screen for cervical malignancies.

    Full Text Available BACKGROUND The aim of this study was to assess and compare the visual outcome of different approaches in the management of dislocated PCIOL. MATERIALS AND METHODS 20 eyes of 20 patients who underwent 3PPPV/anterior vitrectomy to refixate or IOL exchange for dislocation or subluxation of PCIOL from 2012 to 2015. SFIOLs were implanted in 12 patients, IOL refixation was done in four patients and four were left aphakic. This is a retrospective study of 20 eyes of 20 patients with dislocated/subluxated PCIOLs in a tertiary hospital from 2012 to 2015. STATISTICAL ANALYSIS Paired t-test statistical method. RESULTS We retrospectively analysed hospital records of patients who had undergone three PPPV/anterior vitrectomy for posteriorly dislocated/subluxated IOLs 20 eyes of 20 patients were analysed. SFIOLs were implanted in 12 patients, IOL refixation was done in four patients and four were left aphakic. Postoperative BCVA of 6/12 or better was achieved in 66.67% in primary SFIOL, secondary SFIOL and IOL refixation groups. BCVA of <6/60 was seen in all patients left aphakic. Early and late complications were most in aphakic patients. IOL refixation procedure had minimum early and late complications. Subluxated PCIOLs do better than dislocated lens where a successful SFIOL was placed. CONCLUSION IOL refixation procedure has the least complication rate. Early complications of SFIOL management resolve with time. Thus, 3PPPV/anterior vitrectomy with SFIOL and IOL refixation procedures offer a novel approach towards visual rehabilitation of patients with subluxated or dislocated PCIOLs.

  19. Cool episodes in Early Tertiary Arctic climate: Evidence from Svalbard (United States)

    Spielhagen, R. F.; Tripati, A.


    The Arctic is a climatically sensitive and important region. However, very little is known about the climatic and oceanographic evolution of the area, particularly prior to the Neogene. Until recently, the Arctic was assumed to be characterized by relatively warm conditions during the early Cenozoic. The Early Tertiary sedimentary sequence on Svalbard contains several layers with coal seams and broad-leaved plants which were commonly accepted as indicators of a generally temperate-warm climate. Here we report on the intermittent occurrence of certain temperature indicators in the succession, which may represent the first northern high-latitude record of near-freezing temperatures for the early Cenozoic. Besides the findings of probably ice-rafted erratic clasts in the Paleocene and Eocene sandstones and shales, we note especially the occurrence of glendonites which are pseudomorphs of calcite after ikaite (calcium carbonate hexahydrate). We measured the chemical composition of Svalbard glendonites which is almost identical to that of similar pseudomorphs from the Lower Cretaceaous of Northern Canada. Mass spectrometric analyses of the glendonite calcite gave very low carbon isotope values. These values suggest a provenance of the calcium carbonate from marine organic carbon and connect our glendonites to the precursor mineral ikaite which has similar low values. Since a variety of studies has demonstrated that ikaite is stable only at temperatures close to freezing point, we have to infer low temperatures also for the deepositional environment of which the sediments were deposited that now hold glendonites. These results imply the occurrence of cooling phases episodically during the warm background climate of the Paleocene and Eocene, suggesting that temperature variability was much greater than previously recognized.

    Niveen R. M. Elshawa


    Full Text Available Language assessment can be a valuable tool for providing information regarding language teaching. Given the importance of assessment that has undergone much change, there are important issues that warrant investigation, particularly those related to language instructors. Understanding the assessment beliefs of ESL instructors, especially at the tertiary level, is important since it can help improve the quality of assessment practices as well. Therefore, this study investigated English language instructors’ assessment beliefs in the Malaysian context. This study adopted a cross-sectional research design. The survey method was utilized to collect data from six Malaysian universities using a purposive sampling strategy. English language instructors (n=83 were selected via purposive sampling for the study. Findings of the study revealed that English language instructors believed that the purpose of assessment was to improve teaching and learning. Regarding the assessment beliefs that are related to the assessment purposes, analyses of data showed that the items that received the highest percentage of agreement were diagnosing strength and weaknesses in students, providing information about students’ progress and providing feedback to students as they learn, respectively. Although they reported using both formal and informal assessment of their students’ work, English language instructors relied heavily on paper and pencil assessment while giving more weightage on formative assessment. The majority of English language instructors reported employing marking schemes for the courses they taught, carrying out sample marking and providing feedback. Finally, English language instructors reported using different types of assessments for every language skill taught in their language unit/center. The findings highlight the fact that English instructors should be more empowered in their role as the assessors of students. Their knowledge about what, how

  3. Male hypogonadism at a tertiary care hospital in Karachi, Pakistan. (United States)

    Ram, Nanik; Asghar, Ali; Hashmi, Fauzan; Islam, Najmul


    Male hypogonadism is defined as 'inadequate gonadal function, manifested by deficiency in gametogenesis and/or secretion of gonadal hormones'. Signs and symptoms of hypogonadism depend primarily on the age of onset. It can be classified according to the site primarily involved: the gonads, the hypothalamus, or the pituitary gland. The objective this study was to determine the presentation and aetiology of male hypogonadism seen in a tertiary care hospital. This cross-sectional study was conducted at Endocrine Clinics, Aga Khan University Hospital Karachi. Data of male patients with hypogonadism who attended clinics during January 2009 to August 2011 were reviewed. All male patients with clinical and biochemical evidence of hypogonadism were included in the study. Patients with Diabetes Mellitus, Metabolic Syndrome, Andropause, AIDS, Chronic Renal Failure, and Cirrhosis were excluded. Mean +/- SD were computed for quantitative variables. Frequency and percentages were computed for qualitative variables. Aetiology of male hypogonadism was categorised as primary and secondary hypogonadism. A total of 85 patients with male hypogonadism attended the endocrine clinic. Mean age of patients was 25 +/- 10 years. Clinical presentations were small genitalia (65%), absent secondary sexual characteristics (53%), not attained puberty (47%), infertility (53%), erectile dysfunction (41%) and loss of libido (29%). Seventy-three (86%) patients had hypogonadotrophic hypogonadism (secondary hypogonadism) and 12 (14%) patients had hypergonadotrophic hypogonadism (primary hypogonadism). Among the patients with hypogonadotrophic hypogonadism 38 had idiopathic hypogonadotrophic hypogonadsim, 7 had pituitary adenoma, 6 had empty sella syndrome, 3 had Kallman's syndrome, and 1 patient had haemosiderosis due to thalassaemia major; 18 patients did not undergo brain imaging. Small genitalia, absent secondary sexual characteristics and infertility were the main presenting features of hypogonad

    Costa, Liliana; Matos, Ricardo; Júlio, Sara; Vales, Fernando; Santos, Margarida


    Urgent airway management is one of the most important responsibilities of otolaryngologists, often requiring a multidisciplinary approach. Urgent surgical airway intervention is indicated when an acute airway obstruction occurs or there are intubation difficulties. In these situations, surgical tracheostomy becomes extremely important. We retrospectively studied the patients who underwent surgical tracheostomy from 2011 to 2014 by an otolaryngologist team at the operating theater of the emergency department of a tertiary hospital. Indications, complications and clinical evolution of the patients were reviewed. The study included 56 patients (44 men and 12 women) with a median age of 55 years. The procedure was performed under local anesthesia in 21.4% of the patients. Two (3.6%) patients were subjected to conversion from cricothyrostomy to tracheostomy. Head and neck neoplasm was indicated in 44.6% of the patients, deep neck infection in 19.6%, and bilateral vocal fold paralysis in 10.7%. Stridor was the most frequent signal (51.8%). Of the 56 patients, 15 were transferred to another hospital. Among the other 41 patients, 21 were decannulated (average time: 4 months), and none of them were cancer patients. Complications occurred in 5 (12.2%) patients: hemorrhage in 3, surgical wound infection in 1, and cervico-thoracic subcutaneous emphysema in 1. No death was related to the procedure. Urgent tracheostomy is a life-saving procedure for patients with acute airway obstruction or with difficult intubation. It is a safe and effective procedure, with a low complication rate, and should be performed before the patient's clinical status turns into a surgical emergency situation.

  5. Near total parathyroidectomy is effective therapy for tertiary hyperparathyroidism. (United States)

    Dewberry, Lindel Krige; Weber, Collin; Sharma, Jyotirmay


    Tertiary hyperparathyroidism (3°HPT) is defined as persistent hyperparathyroidism with hypercalcemia after renal transplantation. Near total parathyroidectomy (NTPTX) is the current standard for surgical intervention. The purpose of this study was to identify outcomes of NTPTX. A retrospective review was conducted of surgeries performed between 1994 and 2013. NTPTX resulted in resolution of 96.9 per cent of patients' hypercalcemia at a median follow-up of three years (interquartile range [IQR], 1 to 8). However, 3.1 per cent of patients remained hypercalcemic with a mean calcium of 10.5 ± 0.2 mg/dL. A total of 78.4 per cent of patients had parathyroid hormone (PTH) levels below 250 pg/mL at a median follow-up of two years (IQR, 2 to 8). The remaining 21.6 per cent had a median PTH of 535 (IQR, 345 to 857). PTH levels dropped from a median of 745 (IQR, 285.75 to 1594.25) pg/mL to 97 (IQR, 60 to 285) pg/mL one month post-NTPTX (P < 0.01). The most frequent complication was transient hypocalcemia in 27.1 per cent of patients, but no patients became permanently hypocalcemic. In the 1-month postoperative period, only one patient had a cardiac complication, and there was 0 per cent all-cause mortality. Glomerular filtration rate fell from 57.9 ± 28.3 mL/min pre-NTPTX to 53.2 ± 27.5 mL/min at 1-year post-NTPTX (P < 0.01). NTPTX effectively treats hypercalcemia in 3°HPT. However, PTH remains elevated (greater than 250) in 21.6 per cent of patients.

  6. Evidence from lava flows for complex polarity transitions: The new composite Steens Mountain reversal record (United States)

    Jarboe, Nicholas A.; Coe, Robert S.; Glen, Jonathan M. G.


    Geomagnetic polarity transitions may be significantly more complex than are currently depicted in many sedimentary and lava-flow records. By splicing together paleomagnetic results from earlier studies at Steens Mountain with those from three newly studied sections of Oregon Plateau flood basalts at Catlow Peak and Poker Jim Ridge 70–90 km to the southeast and west, respectively, we provide support for this interpretation with the most detailed account of a magnetic field reversal yet observed in volcanic rocks. Forty-five new distinguishable transitional (T) directions together with 30 earlier ones reveal a much more complex and detailed record of the 16.7 Ma reversed (R)-to-normal (N) polarity transition that marks the end of Chron C5Cr. Compared to the earlier R-T-N-T-N reversal record, the new record can be described as R-T-N-T-N-T-R-T-N. The composite record confirms earlier features, adds new west and up directions and an entire large N-T-R-T segment to the path, and fills in directions on the path between earlier directional jumps. Persistent virtual geomagnetic pole (VGP) clusters and separate VGPs have a preference for previously described longitudinal bands from transition study compilations, which suggests the presence of features at the core–mantle boundary that influence the flow of core fluid and distribution of magnetic flux. Overall the record is consistent with the generalization that VGP paths vary greatly from reversal to reversal and depend on the location of the observer. Rates of secular variation confirm that the flows comprising these sections were erupted rapidly, with maximum rates estimated to be 85–120 m ka−1 at Catlow and 130–195 m ka−1 at Poker Jim South. Paleomagnetic poles from other studies are combined with 32 non-transitional poles found here to give a clockwise rotation of the Oregon Plateau of 11.4°± 5.6° with respect to the younger Columbia River Basalt Group flows to the north and 14.5°± 4.6° with respect

  7. Metal-insulator transitions (United States)

    Imada, Masatoshi; Fujimori, Atsushi; Tokura, Yoshinori


    Metal-insulator transitions are accompanied by huge resistivity changes, even over tens of orders of magnitude, and are widely observed in condensed-matter systems. This article presents the observations and current understanding of the metal-insulator transition with a pedagogical introduction to the subject. Especially important are the transitions driven by correlation effects associated with the electron-electron interaction. The insulating phase caused by the correlation effects is categorized as the Mott Insulator. Near the transition point the metallic state shows fluctuations and orderings in the spin, charge, and orbital degrees of freedom. The properties of these metals are frequently quite different from those of ordinary metals, as measured by transport, optical, and magnetic probes. The review first describes theoretical approaches to the unusual metallic states and to the metal-insulator transition. The Fermi-liquid theory treats the correlations that can be adiabatically connected with the noninteracting picture. Strong-coupling models that do not require Fermi-liquid behavior have also been developed. Much work has also been done on the scaling theory of the transition. A central issue for this review is the evaluation of these approaches in simple theoretical systems such as the Hubbard model and t-J models. Another key issue is strong competition among various orderings as in the interplay of spin and orbital fluctuations. Experimentally, the unusual properties of the metallic state near the insulating transition have been most extensively studied in d-electron systems. In particular, there is revived interest in transition-metal oxides, motivated by the epoch-making findings of high-temperature superconductivity in cuprates and colossal magnetoresistance in manganites. The article reviews the rich phenomena of anomalous metallicity, taking as examples Ti, V, Cr, Mn, Fe, Co, Ni, Cu, and Ru compounds. The diverse phenomena include strong spin and

    Energy Technology Data Exchange (ETDEWEB)

    Plotkin, S. E.; Energy Systems


    This report describes the results of an effort to identify key analytic issues associated with modeling a transition to hydrogen as a fuel for light duty vehicles, and using insights gained from this effort to suggest ways to improve ongoing modeling efforts. The study reported on here examined multiple hydrogen scenarios reported in the literature, identified modeling issues associated with those scenario analyses, and examined three DOE-sponsored hydrogen transition models in the context of those modeling issues. The three hydrogen transition models are HyTrans (contractor: Oak Ridge National Laboratory), MARKAL/DOE* (Brookhaven National Laboratory), and NEMS-H2 (OnLocation, Inc). The goals of these models are (1) to help DOE improve its R&D effort by identifying key technology and other roadblocks to a transition and testing its technical program goals to determine whether they are likely to lead to the market success of hydrogen technologies, (2) to evaluate alternative policies to promote a transition, and (3) to estimate the costs and benefits of alternative pathways to hydrogen development.

  11. Internships enhancing entrepreneurial intent and self-efficacy: Investigating tertiary-level entrepreneurship education programmes

    Directory of Open Access Journals (Sweden)

    Melodi Botha


    Full Text Available Background: Entrepreneurship education interventions are deemed effective when they enhance interns’ entrepreneurial intent (EI and entrepreneurial self-efficacy (ESE. Notwithstanding the emergence of internship as an experiential learning approach in entrepreneurship education, evidence about their potential to foster EI and ESE lacks systemisation. Aim: The aim of this study was to determine whether internships enhance EI and ESE. Furthermore, to what extent South African tertiary institutions include internships in their entrepreneurship and management curricula and the obstacles to such inclusion. Setting: South Africa has made a concerted effort to insert an entrepreneurship component across tertiary curricula. The evolution of this entrepreneurship component to experiential learning approaches is, however, unclear. Methods: A qualitative research approach was followed. Firstly, it reviewed empirical evidence for the positive relationship between internships and EI and ESE. Secondly, it conducted a survey of entrepreneurship and business management programmes at all 23 South African tertiary institutions and content analysed the retrieved information to determine whether such programmes include internships. Finally, 10 experts were interviewed to unveil the constraints inhibiting the inclusion of internships in tertiary curricula. Results: The results revealed empirical support for the positive influence of internships on both EI and ESE. Significant lack of inclusion of internships in tertiary curricula in South Africa emerged, owing mainly to administrative issues, curriculum re-design challenges, and lack of mentoring capacity. Conclusion: Tertiary-level entrepreneurship education programmes should include an internship component. The paper suggested that tertiary institutions pilot-test the inclusion of internships with a small number of students and a selected cohort of small business owners.

    A set of brief articles illustrates the emergence of innovating and operational financing tools aimed at supporting energy transition in France and in Europe. As far as France is concerned, different examples are evoked: raising local savings, crowd-funding for renewable energies, citizen investment, cooperation between industries, communities and citizens, a semi-public company with citizen participation, the case of the Nancy urban community, a joint experience by a local public company and an investment fund. As far as Europe is concerned, the following topics or examples are evoked: local policies as lever for European financing, the Danish example of citizen-based financing, crowd-funding in the UK, the European emergence of cooperatives. As far as banks and institutions are concerned, the following topics are addressed: tools implemented by the Caisse des Depots for energy transition, the roles of banks and of public institutions in the financing of energy transition

  15. Electroweak phase transitions

    International Nuclear Information System (INIS)

    Anderson, G.W.


    An analytic treatment of the one Higgs doublet, electroweak phase transition is given. The phase transition is first order, occurs by the nucleation of thin walled bubbles and completes at a temperature where the order parameter, left-angle φ right-angle T is significantly smaller than it is when the origin becomes absolutely unstable. The rate of anomalous baryon number violation is an exponentially function of left-angle φ right-angle T . In very minimal extensions of the standard model it is quite easy to increase left-angle φ right-angle T so that anomalous baryon number violation is suppressed after completion of the phase transition. Hence baryogenesis at the electroweak phase transition is tenable in minimal of the standard model. In some cases additional phase transitions are possible. For a light Higgs boson, when the top quark mass is sufficiently large, the state where the Higgs field has a vacuum expectation value left-angle φ right-angle = 246 GeV is not the true minimum of the Higgs potential. When this is the case, and when the top quark mass exceeds some critical value, thermal fluctuations in the early universe would have rendered the state left-angle φ right-angle = 246 GeV unstable. The requirement that the state left-angle φ right-angle = 246 GeV is sufficiently long lived constrains the masses of the Higgs boson and the top quark. Finally, we consider whether local phase transitions can be induced by heavy particles which act as seeds for deformations in the scalar field

  18. Pinocchio: Geppetto's transitional object

    Directory of Open Access Journals (Sweden)

    Gabriele Zeloni


    Full Text Available The literature has been considered by Freud and others after him, a form of unaware exploration of mind that can leads to discoveries similar to psychoanalysis’s discoveries. From this perspective, the author puts forward the following hypothesis: Pinocchio is a puppet who comes to life and is therefore, from a child's perception, a transitional object according to Winnicott.

    From the Atlantic Ocean to the Baltic Sea, from Portugal to Poland through UK, Germany or Austria, energy transition is in progress everywhere in Europe, but at different rhythms and in various conditions from one country to the other. How does the European framework promote the energy transition at the local and regional scales? What advantages the most advanced countries are relying on? How do citizens and local projects take over slow or retrograde governmental policies? This dossier gives some elements of answer through an overview of some energy policy scenarios under implementation in some European countries (Germany, Portugal, Denmark, Austria, UK, Spain)

    Dean, S.O.


    Fusion is beginning its transition from a scientific research programme to that of an engineering development programme aimed at practical applications. This transition is likely to last a decade or more because many scientific questions remain and because of the magnitude and cost of the engineering issues. This article reviews briefly the encouraging results produced at the Joint European Torus (JET) where 1.7 MW of fusion power was generated for 2 seconds in experiments in November 1991, the remaining scientific issues, the role of near-term experimental reactors like the International Thermonuclear Experimental reactor (ITER) and other approaches to a demonstration power plant.

    Electronic Phase Transitions deals with topics, which are presently at the forefront of scientific research in modern solid-state theory. Anderson localization, which has fundamental implications in many areas of solid-state physics as well as spin glasses, with its influence on quite different research activities such as neural networks, are two examples that are reviewed in this book. The ab initio statistical mechanics of structural phase transitions is another prime example, where the interplay and connection of two unrelated disciplines of solid-state theory - first principle ele

  2. Glaucoma Blindness at a Tertiary Eye Care Center. (United States)

    Stone, Jordan S; Muir, Kelly W; Stinnett, Sandra S; Rosdahl, Jullia A


    Glaucoma is an important cause of irreversible blindness. This study describes the characteristics of a large, diverse group of glaucoma patients and evaluates associations between demographic and clinical characteristics and blindness. Data were gathered via retrospective chart review of patients (N = 1,454) who were seen between July 2007 and July 2010 by glaucoma service providers at Duke Eye Center. Visual acuity and visual field criteria were used to determine whether patients met the criteria for legal blindness. Descriptive and comparative statistical analyses were performed on the glaucoma patients who were not blind (n = 1,258) and those who were blind (n = 196). A subgroup analysis of only those patients with primary open-angle glaucoma was also performed. In this tertiary care population, 13% (n = 196) of glaucoma patients met criteria for legal blindness, nearly one-half of whom (n = 94) were blind from glaucoma, and another one-third of whom (n = 69) had glaucoma-related blindness. The most common glaucoma diagnosis at all levels of vision was primary open-angle glaucoma. A larger proportion of black patients compared with white patients demonstrated vision loss; the odds ratio (OR) for blindness was 2.25 (95% CI, 1.6-3.2) for black patients compared with white patients. The use of systemic antihypertensive medications was higher among patients who were blind compared with patients who were not blind (OR = 2.1; 95% CI, 1.4-3.1). A subgroup analysis including only patients with primary open-angle glaucoma showed similar results for both black race and use of systemic antihypertensive medications. The relationship between use of systemic antihypertensive medications and blindness was not different between black patients and white patients (interaction P = .268). Data were based on chart review, and associations may be confounded by unmeasured factors. Treated systemic hypertension may be correlated with blindness, and the cause cannot be explained solely

    Abstract Background herpes zoster (HZ) is a common infection with potential complications requiring hospital care, especially for patients with multiple comorbities. However, there is little information on HZ from hospital registries. Methods we searched for hospital-based records of B02 code (ICD-10) between March 2000 and January 2017 at Hospital de Clínicas de Porto Alegre, a tertiary, university hospital in south Brazil. To avoid misclassifications, we considered clinical evaluation for the diagnosis of cutaneous HZ and postherpetic neuralgia (PHN), ophthalmological evaluation for ophthalmic HZ and the combination of clinical, radiologic and cerebrospinal fluid analysis for HZ meningo-encephalitis (ME). We analyzed conditions associated with immune dysregulation, complications, length of hospital stay, and mortality. Chi-square test and Kaplan-Meier estimator were used for statistical analyses. P < 0.05 was considered statistically significant. Results there were 847 records for this period, of which 801 were confirmed according to our criteria and included in the analysis. Most patients were women (n = 448; 60%), with an average of 48.8 years, standard deviation of 22.2. There were more diagnoses in the inpatients group (74.4%), and fewer in the emergency room (22.4%) and outpatient (3.3%). The median length of hospital stay was 7 days (2-10, P25-P75) when HZ was the main reason for admission. Most patients presented cutaneous HZ (n = 743, 92.8%). There were fewer cases of PHN (6.1%), ophthalmic HZ (7.6%) and ME (4.1%). Seventy percent had some kind of immune dysregulation; more frequently AIDS (31%), use of immunosuppressive agents (18.7%) and malignant disease (16.2%). We followed the subjects for a median of 28.2 (2.8-77.5) months. During this period, there were 105 (13.1%) deaths. Five were related to HZ ME. The 30-day overall mortality rate was 1.5%. There was no statistical difference in cumulative survival (graph 1, P = 0.05) or incidence of

    Celiac disease is an immune-mediated disorder with a multiform presentation and therefore a challenging diagnosis. Our purpose is to identify the epidemiological, clinical, laboratory and histologic characteristics of children with celiac disease at diagnosis and on follow-up. Children with previously established or newly diagnosed celiac disease, admitted in a tertiary centre in a two-year period (2014-2016) were recruited. Data was collected retrospectively from electronic medical records and clinical notes, and subsequently analysed with SPSS version 20.0. A total of 159 patients, out of 312, were included. Age ranged from 1 to 17 years (mean ± SD: 8.5±4.5 years, 69% girls). Disease presentation was classical in 60%, non-classical in 25%, subclinical in 10% and 5% classified as potential celiac disease. Non-classical and subclinical profiles had a higher mean age at presentation but not statistically significant (P-value 0.24). The most frequent gastrointestinal features at presentation were abdominal pain (58%), diarrhea (43%) and bloating (27%). A positive family history for celiac disease was present in 24% (n=35). We found anaemia in 23%, low ferritin in 63% and a moderate to severe deficiency of 25-hydroxyvitamin D in 62%. celiac disease -specific serologic testing and esophagogastroduodenoscopy were performed in 99%. Histology revealed modified Marsh 2 or 3 enteropathy in 94%, the remaining had normal histology but positive human leukocyte antigen typing. Clinical improvement at 12 months of gluten-free diet was complete in 51% and partial in 49%. IgA tTG normalized after 12-30 months of gluten-free diet in 45%. On growth assessment at diagnosis and after 12-28 months of gluten-free diet, 100% had height increase (mean ±SD: 7.11±4.43 cm) and 96% weight gain (mean ±SD: 5.60±4.91 kg). Our findings outline the diverse clinical presentations of pediatric celiac disease that should be considered irrespective of age. Increased clinician's awareness will

    An integrated study of variation in siliceous microfossils, lithofacies, and other geochemical guides to environmental conditions through the Cretaceous/Tertiary (K/T) boundary transition at Flaxbourne River and Woodside Creek, coastal eastern Marlborough, indicates that the K/T impact disrupted oceanic conditions along the continental margin of eastern New Zealand for c. 1 m.y. Initial effects of the K/T event were a major reduction in carbonate production, associated with calcareous plankton extinctions, and significant increases in terrigenous clay and biogenic silica content. An absence of radiolarian extinctions or significant negative excursions in paleo-productivity indicators (Ba, delta 13 C at the boundary, followed by rapid increases in the abundance of diatoms and spumellarian radiolarians, indicate that biogenic silica production partly compensated for the collapse in calcareous plankton. The earliest Paleocene recovery of calcareous plankton was short-lived, giving way to a progressive increase in siliceous plankton abundance over c. 500,000 yr, which culminated in a c. 400,000 yr episode of peak biogenic silica production. The dominance of siliceous facies, coupled with the abundance of diatoms and spumellarian radiolarians, indicates climatic or oceanic conditions were significantly cooler than in the Late Cretaceous. Stepped increases in biogenic silica production show c. 100,000 yr periodicity, suggesting that Early Paleocene lithofacies changes were influenced by climate forcing agents at the eccentricity bandwidth.

    Ascertainment bias (AB) indicates a bias of an evaluation centre in estimating the prevalence/incidence of a disease due to the specific expertise of the centre. The aim of our study was to evaluate classification of different types of dementia in new cases appearing in secondary and tertiary centres, in order to evidence possible occurrence of AB in the various (secondary to tertiary) dementia centres. To assess the mechanism of AB, the rates of new cases of the different forms of dementia reported by different centres were compared. The centres involved in the study were 11 hospital-based centres including a tertiary centre, located in the University Department of Clinical Neurology. The tertiary centre is endowed with state-of-the-art diagnostic facilities and its scientific production is prominently focused on dementia with Lewy bodies (DLB) thus suggesting the possible occurrence of a bias. Four main categories of dementia were identified: Alzheimer's disease (AD), DLB, fronto-temporal dementia (FTD), vascular dementia (VaD), with other forms in a category apart. The classification rate of new cases of dementia in the tertiary centre was compared with rates reported by secondary centres and rates of recoding were calculated during a follow-up of 2 years. The study classified 2,042 newly diagnosed cases of dementia in a population of 1,370,000 inhabitants of which 315,000 were older than 65. AD was categorized in 48-52 % of cases, DLB in 25-28 %, FTD in 2-4 % and VaD in 17-28 %. During the 2-year follow-up the diagnosis was re-classified in 40 patients (3 %). The rate of recoding was 5 % in the tertiary centre, 2-8 % in referrals from secondary to tertiary centre, 2-10 % in recodings performed in secondary centres and addressed to tertiary centre. Recoding or percentages of new cases of AD or DLB were not different in the comparison between secondary or between secondary and tertiary centres. FTD and VaD were instead significantly recoded. The results

    To define the clinical characteristics, and to assess the management of colonoscopic complications at a local clinic. A retrospective review of the medical records was performed for the patients with iatrogenic colon perforations after endoscopy at a local clinic between April 2006 and December 2010. Data obtained from a tertiary hospital in the same region were also analyzed. The underlying conditions, clinical presentations, perforation locations, treatment types (operative or conservative) and outcome data for patients at the local clinic and the tertiary hospital were compared. A total of 10  826 colonoscopies, and 2625 therapeutic procedures were performed at a local clinic and 32  148 colonoscopies, and 7787 therapeutic procedures were performed at the tertiary hospital. The clinic had no perforations during diagnostic colonoscopy and 8 (0.3%) perforations were determined to be related to therapeutic procedures. The perforation rates in each therapeutic procedure were 0.06% (1/1609) in polypectomy, 0.2% (2/885) in endoscopic mucosal resection (EMR), and 3.8% (5/131) in endoscopic submucosal dissection (ESD). Perforation rates for ESD were significantly higher than those for polypectomy or EMR (P hospital. Six perforations occurred with therapeutic endoscopy (perforation rate, 0.08%; 1 per 1298 procedures). Perforation rates for specific procedure types were 0.02% (1 per 5500) for polypectomy, 0.17% (1 per 561) for EMR, 2.3% (1 per 43) for ESD in the tertiary hospital. There were no differences in the perforation rates for each therapeutic procedure between the clinic and the tertiary hospital. The incidence of iatrogenic perforation requiring surgical treatment was quite low in both the clinic and the tertiary hospital. No procedure-related mortalities occurred. Performing closure with endoscopic clipping reduced the C-reactive protein (CRP) titers. The mean maximum CRP titer was 2.9 ± 1.6 mg/dL with clipping and 9.7 ± 6.2 mg/dL without clipping

  9. Excited state intramolecular charge transfer reaction in binary mixtures of water and tertiary butanol (TBA): alcohol mole fraction dependence. (United States)

    Pradhan, Tuhin; Ghoshal, Piue; Biswas, Ranjit


    The excited state intramolecular charge transfer reaction of 4-(1-azetidinyl)benzonitrile (P4C) has been studied in water-tertiary butanol (TBA) mixtures at different alcohol mole fractions by using steady state and time-resolved fluorescence spectroscopy. The ratio between the areas under the locally excited (LE) and charge transferred (CT) emission bands is found to exhibit a sharp rise at alcohol mole fraction approximately 0.04, a value at which several thermodynamic properties of this mixture is known to show anomalous change due to the enhancement of H-bonding network. The radiative rate associated with the LE emission also shows a maximum at this TBA mole fraction. Although the structural transition from the water-like tetrahedral network to the alcohol-like chain is reflected in the red shift of the absorption spectrum up to TBA mole fraction approximately 0.10, the emission bands (both LE and CT) show the typical nonideal alcohol mole fraction dependence at all TBA mole fractions. Quantum yield, CT radiative rate as well as transition moments also exhibit a nonideal alcohol mole fraction dependence. The time-resolved emission decay of P4C has been found to be biexponential at all TBA mole fractions, regardless of emission collection around either the LE or the CT bands. The time constant associated with the slow component (tau(slow)) shows a minimum at TBA mole fraction approximately 0.04, whereas such a minimum for the fast time constant, tau(fast) (representing the rate of LE --> CT conversion reaction) is not observed. The nonobservation of the minimum in tau(fast) might be due to the limited time resolution employed in our experiments.

  10. Life Cycle Assessment of urban wastewater reuse with ozonation as tertiary treatment

    Munoz, Ivan; Rodriguez, Antonio; Rosal, Roberto; Fernandez-Alba, Amadeo R.


    Life Cycle Assessment has been used to compare different scenarios involving wastewater reuse, with special focus on toxicity-related impact categories. The study is based on bench-scale experiments applying ozone and ozone in combination with hydrogen peroxide to a wastewater effluent from a Spanish sewage treatment plant. Two alternative characterisation models have been used to account for toxicity of chemical substances, namely USES-LCA and EDIP97. Four alternative scenarios have been assessed: wastewater discharge plus desalination supply, wastewater reuse without tertiary treatment, wastewater reuse after applying a tertiary treatment consisting on ozonation, and wastewater reuse after applying ozonation in combination with hydrogen peroxide. The results highlight the importance of including wastewater pollutants in LCA of wastewater systems assessing toxicity, since the contribution of wastewater pollutants to the overall toxicity scores in this case study can be above 90%. Key pollutants here are not only heavy metals and other priority pollutants, but also non-regulated pollutants such as pharmaceuticals and personal care products. Wastewater reuse after applying any of the tertiary treatments considered appears as the best choice from an ecotoxicity perspective. As for human toxicity, differences between scenarios are smaller, and taking into account the experimental and modelling uncertainty, the benefits of tertiary treatment are not so clear. From a global warming potential perspective, tertiary treatments involve a potential 85% reduction of greenhouse gas emissions when compared with desalination

    In principle new technique was elaborated for obtaining the alloys of refractory metals by their hydrides compacting and following dehydrogenation. The elaborated technique is described. The conditions of alloys formation from different hydrides of appropriate metals was investigated in detail. The influence of the process parameters such as: chemical peculiarities, composition of source hydrides, phase transformation during dehydrogenation, etc. on the alloys formation were established. The binary and tertiary alloys of α and ω phases: Ti 0 .8Zr 0 .8; Ti 0 .66Zr 0 .33; Ti 0 .3Zr 0 .8; Ti 0 .2Zr 0 .8; Ti 0 .8Hf 0 .2; Ti 0 .6Hf 0 .4Ti 0 .66Zr 0 .23Hf 0 .11; etc were recieved. Using elaborated special hydride cycle, an earlier unknown effective process for formation of alloys of transition metals was realized. The dependence of final alloy structure on the composition of initial mixture and hydrogen content in source hydrides was established

  12. Transition pedagogies and the neoliberal episteme: What do academics think?

    Directory of Open Access Journals (Sweden)

    Kate Hughes


    Full Text Available There has been much discussion of the massification of higher education and its impact on contemporary universities in terms of increased demands on academic staff in the context of neoliberal managerialism, and the power regimes which govern the sector. Less is written about the pedagogies used under neoliberalism. Many academics view tertiary education as both an individually and socially transformative process, and there is a sense that the current discursive environment engenders an inertia wherein this commitment is lost. This paper focusses on a small qualitative study of staff working in two universities at the bottom of the league tables. Their perceptions of pedagogical work and their views of their transformative potential under neoliberalism is discussed. The argument is made that there is the potential for building a space for critical education in contemporary universities. This article explores these issues, arguing that the use of transition pedagogies can create a transformative education.

  2. Study of tertiary creep instability in several elevated-temperature structural materials

    International Nuclear Information System (INIS)

    Booker, M.K.; Sikka, V.K.


    Data for a number of common elevated temperature structural materials have been analyzed to yield mathematical predictions for the time and strain to tertiary creep at various rupture lives and temperatures. Materials examined include types 304 and 316 stainless steel, 2 1/4 Cr-1 Mo steel, alloy 800H, alloy 718, Hastelloy alloy X, and ERNiCr--3 weld metal. Data were typically examined over a range of creep temperatures for rupture lives ranging from less than 100 to greater than 10,000 hours. Within a given material, trends in these quantities can be consistently described, but it is difficult to directly relate the onset of tertiary creep to failure-inducing instabilities. A series of discontinued tests for alloy 718 at 649 and 620 0 C showed that the material fails by intergranular cracking but that no significant intergranular cracking occurs until well after the onset of tertiary creep

  3. Early Tertiary magmatism and probable Mesozoic fabrics in the Black Mountains, Death Valley, California (United States)

    Miller, Martin G.; Friedman, Richard M.


    We report two early Tertiary U-Pb zircon ages for pegmatite from the Black Mountains of Death Valley, California. These ages, 54.7 ± 0.6 Ma and 56 ± 3 Ma, are unique for much of southeastern California. The samples belong to a pegmatite suite that occupies part of the footwall of the Badwater turtleback, a late Tertiary extensional feature; similar but undated pegmatite intrudes the footwalls of the Copper Canyon and Mormon Point turtlebacks farther south. The pegmatite suite demonstrates that fabric development on the turtlebacks was at least a two-stage process. Fabrics cut by these pegmatites likely formed during the Mesozoic, whereas those that involve them formed during late Tertiary extension.

  4. Accessibility of tertiary hospitals in Finland: A comparison of administrative and normative catchment areas. (United States)

    Huotari, Tiina; Antikainen, Harri; Keistinen, Timo; Rusanen, Jarmo


    The determination of an appropriate catchment area for a hospital providing highly specialized (i.e. tertiary) health care is typically a trade-off between ensuring adequate client volumes and maintaining reasonable accessibility for all potential clients. This may pose considerable challenges, especially in sparsely inhabited regions. In Finland, tertiary health care is concentrated in five university hospitals, which provide services in their dedicated catchment areas. This study utilizes Geographic Information Systems (GIS), together with grid-based population data and travel-time estimates, to assess the spatial accessibility of these hospitals. The current geographical configuration of the hospitals is compared to a normative assignment, with and without capacity constraints. The aim is to define optimal catchment areas for tertiary hospitals so that their spatial accessibility is as equal as possible. The results indicate that relatively modest improvements can be achieved in accessibility by using normative assignment to determine catchment areas. Copyright © 2017 Elsevier Ltd.

  6. The Mongolia experience: transitioning within transition. (United States)

    MacKenzie, Richard G


    Although Mongolia has a long and distinguished history, as a new and emerging democracy it is experiencing the pains of transition-one that is moving the country from its pastoral and nomadic past into the 21st century. Confounded by its previous dependence on socialist Soviet Russia, the concept of a market economy seems opportunistic for some, while for those living within the traditional lifestyle of the herdsman in the countryside it is confusing and threatening to family structure and values. Adolescents and young adults are caught at the interface-not only of their own development, but by the disparities between tradition and Western values, new technology, and freedoms granted by the emerging democracy, and by the civic practice of democracy itself. Conceptually the new belongs to the young, and yet limited health and educational resources are available to modulate and focus both threats and opportunities. Using the analogy of the spirit banner of the warrior, it is the young as the warriors of the 21st century who have the energy and investment in the future that will be needed to shepherd this change. Both personal and public health, within the context of development, the psychobiological model, and the political and social ecology will be strong determinants of success. It is a parallel investment in both youth and the ideals they represent that will ensure success for the new Mongolia.

  7. Tertiary paediatric emergency department use in children and young people with cerebral palsy. (United States)

    Meehan, Elaine; Reid, Susan M; Williams, Katrina; Freed, Gary L; Babl, Franz E; Sewell, Jillian R; Rawicki, Barry; Reddihough, Dinah S


    The aim of this study was to describe the pattern of tertiary paediatric emergency department (ED) use in children and young people with cerebral palsy (CP). A retrospective analysis of ED data routinely collected at the two tertiary paediatric hospitals in Victoria, Australia, cross-matched with the Victorian Cerebral Palsy Register. Data pertaining to the ED presentations of 2183 registered individuals born 1993-2008 were obtained. Between 2008 and 2012, 37% (n = 814) of the CP cohort had 3631 tertiary paediatric ED presentations. Overall, 40% (n = 332) of presenters were residing in inner metropolitan Melbourne; 44% (n = 356) in outer Melbourne; and 13% (n = 108) in regional Victoria. Presenters were more likely than non-presenters to be younger, non-ambulant and have epilepsy. In total, 71% of presentations were triaged as Australasian Triage Scale 1-3 (urgent), and 44% resulted in a hospital admission. Disorders of the respiratory, neurological and gastrointestinal systems, and medical device problems were responsible for 72% of presentations. Many of the tertiary paediatric ED presentations in this group were appropriate based on the high admission rate and the large proportion triaged as urgent. However, there is evidence that some families are bypassing local services and travelling long distances to attend the tertiary paediatric ED, even for less urgent complaints that do not require hospital admission. Alternative pathways of care delivery, and strategies to promote the management of common problems experienced by children and young people with CP in non-paediatric EDs or primary care settings, may go some way towards reducing unnecessary tertiary paediatric ED use in this group. © 2015 The Authors.

  9. Chemical Properties, Decomposition, and Methane Production of Tertiary Relict Plant Litters: Implications for Atmospheric Trace Gas Production in the Early Tertiary (United States)

    Yavitt, J. B.; Bartella, T. M.; Williams, C. J.


    Throughout the early Tertiary (ca. 65-38 Ma) Taxodiaceae-dominated (redwood) wetland forests occupied the high latitudes and were circumpolar in their distribution. Many of these forests had high standing biomass with moderate primary productivity. The geographic extent and amount of Tertiary coals and fossil forests throughout Arctic Canada suggests large areas of wetland forests that may have cycled substantial quantities of carbon, particularly methane until they were replaced by cold tolerant Pinus, Picea, and Larix following climatic cooling associated with the Terminal Eocene Event. To test this hypothesis we compared physiochemical properties, decomposition, and trace gas production of litter from extant Metasequoia, Pinus, Picea, and Larix. Initial results from plantation-grown trees indicate Metasequoia litter is a better source of labile organic substrate than pinaceous litter. Metasequoia litter contained the least lignin and highest amounts of water-soluble compounds of the four litter types studied. Analysis of the lignin structure using cupric oxide oxidation indicates that Metasequoia lignin is enriched in 4'-hydroxyacetophenone and 4'- Hydroxy-3'-methoxyacetophenone relative to the pinaceous litter. In a 12-month decomposition study using litterbags, average litter mass loss was greater for Metasequoia litter (62%) compared to the pinaceous species (50%). Moreover, Metasequoia litter incubated under anoxic conditions produced nearly twice as much CO2 (ca. 4.2 umol/ and CH4 (2.1 umol/ as the pinaceous litter (2.4 umol/ for CO2; 1.2 umol/ for CH4). Our results support the idea of greater decomposability and palatability of Metasequoia litter as compared to Larix, Picea, or Pinus. Provided that the biochemical properties of Metasequoia have remained relatively stable through geologic time, it appears that early Tertiary Metasequoia-dominated wetland forests may have had higher microbial driven trace gas production than the

  10. Palynological and iridium anomalies at Cretaceous-Tertiary boundary, south-central Saskatchewan (United States)

    Nichols, D.J.; Jarzen, D.M.; Orth, C.J.; Oliver, P.Q.


    The Cretaceous-Tertiary boundary in south-central Saskatchewan is marked by coincident anomalies in abundance of iridium and fern spores at the extinction level of a suite of Cretaceous pollen taxa. Evidence of disruption of the terrestrial flora includes the fern-spore abundance anomaly and local extinction of as much as 30 percent of angiosperm species. The reorganized earliest Tertiary flora is made up largely of surviving species that assumed new roles of dominance. Persistence of climatically sensitive taxa across the boundary indicates that if paleoclimate was altered by the terminal Cretaceous event, it returned quickly to the pre-event condition.

  11. Tandem catalytic allylic amination and [2,3]-Stevens rearrangement of tertiary amines. (United States)

    Soheili, Arash; Tambar, Uttam K


    We have developed a catalytic allylic amination involving tertiary aminoesters and allylcarbonates, which is the first example of the use of tertiary amines as intermolecular nucleophiles in metal-catalyzed allylic substitution chemistry. This process is employed in a tandem ammonium ylide generation/[2,3]-rearrangement reaction, which formally represents a palladium-catalyzed Stevens rearrangement. Low catalyst loadings and mild reaction conditions are compatible with an unprecedented substrate scope for the ammonium ylide functionality, and products are generated in high yields and diastereoselectivities. Mechanistic studies suggested the reversible formation of an ammonium intermediate.

    Tertiary in-situ leachable mineralization in Songliao Basin was analyzed in theory in the past. Since 1998, regional investigation at 1:200000 scale has been done with about 120 holes drilled. Based on drill holes recording, section compiling and sample analysis, the authors investigate into the Tertiary in-situ leachable conditions including rock character, sedimentary facies, rock chemistry, organic substances, uranium content, sandstone porosity, sandstone bodies, interlayer oxidation, and hydro-dynamic value. The study would play important role in prospecting for in-situ leachable uranium in South Songliao basin

  13. Jamming transitions in cancer (United States)

    Oswald, Linda; Grosser, Steffen; Smith, David M.; Käs, Josef A.


    The traditional picture of tissues, where they are treated as liquids defined by properties such as surface tension or viscosity has been redefined during the last few decades by the more fundamental question: under which conditions do tissues display liquid-like or solid-like behaviour? As a result, basic concepts arising from the treatment of tissues as solid matter, such as cellular jamming and glassy tissues, have shifted into the current focus of biophysical research. Here, we review recent works examining the phase states of tissue with an emphasis on jamming transitions in cancer. When metastasis occurs, cells gain the ability to leave the primary tumour and infiltrate other parts of the body. Recent studies have shown that a linkage between an unjamming transition and tumour progression indeed exists, which could be of importance when designing surgery and treatment approaches for cancer patients.

  14. Energy transition in France

    International Nuclear Information System (INIS)

    Grandjean, Alain


    After having recalled the main issues and stakes addressed by the French national debate on energy transition (strategic stakes, priority to a reduction of French energy consumption, options for the evolution of the French energy mix), the author comments the possible evolution of energy prices and of the energy taxing policy (evolution of oil prices, carbon price). In a second part, the author addresses the issue of financing of building and housing renovation. He shows that this operation cannot be only based on financial markets which are not efficient. This means that a public intervention is required, and different solutions are then possible. Some of them seem difficult to implement (creation of money by the central Bank, creation of a public bank which could lend money to private actors), and some others need to be further examined (creation of a financing company for energy transition, use of national savings, simplified circuits for a financing of local projects by local savings, and so on)

  17. Vacancies in transition metals

    International Nuclear Information System (INIS)

    Allan, G.; Lannoo, M.


    A calculation of the formation energy and volume for a vacancy in transition metals is described. A tight-binding scheme is used for the d band and a Born-Mayer type potential to account for the repulsive part of the energy at small distances. The results show that the relaxation energy is small in all cases, less than 0.1 eV. This seems to be coherent with the good agreement obtained for the theoretical and experimental values of the formation energy Esub(F)sup(V) of the vacancy, without including relaxation. The center of the transitional series is found to give a contraction (Formation volume of order -0.4 at.vol.) whereas the edges are found to produce dilations. (author)

  1. Stimulated coherent transition radiation

    International Nuclear Information System (INIS)

    Hung-chi Lihn.


    Coherent radiation emitted from a relativistic electron bunch consists of wavelengths longer than or comparable to the bunch length. The intensity of this radiation out-numbers that of its incoherent counterpart, which extends to wavelengths shorter than the bunch length, by a factor equal to the number of electrons in the bunch. In typical accelerators, this factor is about 8 to 11 orders of magnitude. The spectrum of the coherent radiation is determined by the Fourier transform of the electron bunch distribution and, therefore, contains information of the bunch distribution. Coherent transition radiation emitted from subpicosecond electron bunches at the Stanford SUNSHINE facility is observed in the far-infrared regime through a room-temperature pyroelectric bolometer and characterized through the electron bunch-length study. To measure the bunch length, a new frequency-resolved subpicosecond bunch-length measuring system is developed. This system uses a far-infrared Michelson interferometer to measure the spectrum of coherent transition radiation through optical autocorrelation with resolution far better than existing time-resolved methods. Hence, the radiation spectrum and the bunch length are deduced from the autocorrelation measurement. To study the stimulation of coherent transition radiation, a special cavity named BRAICER is invented. Far-infrared light pulses of coherent transition radiation emitted from electron bunches are delayed and circulated in the cavity to coincide with subsequent incoming electron bunches. This coincidence of light pulses with electron bunches enables the light to do work on electrons, and thus stimulates more radiated energy. The possibilities of extending the bunch-length measuring system to measure the three-dimensional bunch distribution and making the BRAICER cavity a broadband, high-intensity, coherent, far-infrared light source are also discussed

  2. Kondo-Anderson transitions (United States)

    Kettemann, S.; Mucciolo, E. R.; Varga, I.; Slevin, K.


    Dilute magnetic impurities in a disordered Fermi liquid are considered close to the Anderson metal-insulator transition (AMIT). Critical power-law correlations between electron wave functions at different energies in the vicinity of the AMIT result in the formation of pseudogaps of the local density of states. Magnetic impurities can remain unscreened at such sites. We determine the density of the resulting free magnetic moments in the zero-temperature limit. While it is finite on the insulating side of the AMIT, it vanishes at the AMIT, and decays with a power law as function of the distance to the AMIT. Since the fluctuating spins of these free magnetic moments break the time-reversal symmetry of the conduction electrons, we find a shift of the AMIT, and the appearance of a semimetal phase. The distribution function of the Kondo temperature TK is derived at the AMIT, in the metallic phase, and in the insulator phase. This allows us to find the quantum phase diagram in an external magnetic field B and at finite temperature T. We calculate the resulting magnetic susceptibility, the specific heat, and the spin relaxation rate as a function of temperature. We find a phase diagram with finite-temperature transitions among insulator, critical semimetal, and metal phases. These new types of phase transitions are caused by the interplay between Kondo screening and Anderson localization, with the latter being shifted by the appearance of the temperature-dependent spin-flip scattering rate. Accordingly, we name them Kondo-Anderson transitions.

  9. The energy transition

    International Nuclear Information System (INIS)

    Defeuilley, Christophe


    In a first part, the author proposes an analysis of energy transition and of its consequences on the competitive environment. He recalls the main characteristics of energy transition and more particularly focuses on two aspects: the development of renewable energies and the management of demand. Thus, the author discusses the following issues: the relationship between the struggle against climate change and the low carbon economy, the development of renewable energies, the evolution and main actors of photovoltaic array and of wind turbine production, the distribution of photovoltaic and wind energy installed production among countries, and some key figures about the main renewable energy operators in Europe. He discusses how to manage consumptions, and operations performed. In a second part, the author addresses the impact of the German energy transition (Energiewende) on the business models of the main German energy operators (RWE and E.On). He recalls and comments the objective of this energy policy, presents the German electric and gas sector, comments the evolution of the electric utilities since 1998, more presently presents and discusses the activities of RWE and E.On, the evolution of their main financial indicators, and the levels of installed power with respect of energy sources

  10. Energy systems in transition

    International Nuclear Information System (INIS)

    Haefele, W.


    The principal point of the author was to discuss energy systems (ES) in transition, transition addresses the next 10-25 years, and strategy of the transition. He considers different scenarios of future development of ES. Further he presents considerations elaborated during the last years on the concept of novel horizontally integrated ES which gives promise to be at least an approximation to the desired object of no emissions. The main ideas of the concept are: to decompose and thereby clean all the primary inputs before they are brought to combustion; to develop a network combining all the primary inputs to an integrated supply structure of high absorption, buffer, and storage capacity that resembles in some way the supply and utility functions of the well established electric grid but completes it at best on the basis of mass flows; to achieve a high flexibility in supplying the final energy. The author considers the long run perspective of hydrogen, solar, and nuclear energy with respect to alternative energy sources. 6 refs, 24 figs

    Coralia Angelescu


    Full Text Available The transitional recession in countries of Eastern Europe has been much longer than expected. The legacy and recent policy mistakes have both contributed to the slow progress. As structural reforms and gradual institution building have taken hold, the post-socialist economics have started to recover, with some leading countries building momentum toward faster growth. There is a possibility that in wider context of globalization several of these emerging market economies will be able to catch up with the more advanced industrial economies in a matter of one or two generations. Over the past few years, most candidate countries have made progress in the transition to a competitive market economy, macroeconomic stabilization and structural reform. However their income levels have remained far below those in the Member States. Measured by per capita income in purchasing power standards, there has been a very limited amount of catching up over the past fourteen years. Prior, the distinctions between Solow-Swan model and endogenous growth model. The interdependence between transition and integration are stated in this study. Finally, some measures of macroeconomic policy for sustainable growth are proposed in correlation with real macroeconomic situation of the Romanian economy. Our study would be considered the real convergence for the Romanian economy and the recommendations for the adequate policies to achieve a fast real convergence and sustainable growth.

Long wave chaotic hysteretic investment cycles emerge under socialism leading to crisis and breakdown. Macroeconomic collapse occurs with bifurcations of coordination structures during transition. During recovery, transitional cobweb labor market dynamics exhibit chaos, fractal basin boundaries between coexisting non-chaotic attractors, discontinuous phase transitions, strange attractors, and cascades of infinitely many period-doubling bifurcations.

  2. Source of sulphur in the Ebro Basin (Northern Spain). Tertiary nonmarine evaporite deposits as evidenced by sulphur isotopes

    International Nuclear Information System (INIS)

    Birnbaum, S.J.; Coleman, D.


    The Ebro Basin is an intermontane basin, located in northern Spain, filled with Tertiary (largely Oligocene and Miocene) elastic and chemical deposits. Sulphur isotopes are utilized to determine the source of sulphur in the sulphate deposits (predominantly gypsum with accessory thenardite, mirabolite and epsomite). Data obtained from Tertiary gypsum rocks produce a range of delta 34 S values from +9.16% to + 14.02% with a mean of +13.61%. Data obtained from Triassic gypsum rocks (in source area) produce a range from +13.73% to +15.14%, with a mean of +14.66%. Values for Tertiary marine water range from +18% to +24%. These data indicate a nonmarine origin for sulpur within the Tertiary sulphate rocks. The contribution of Triassic sulphur to the groundwater system, plus varying degrees of dilution by isotopically lighter (atmospheric and sulphide) sulphur, best explains the isotopic ratios observed in the Tertiary Basin deposits.

  9. Evaluation of the onset of tertiary creep for types 304 and 316 stainless steels

    International Nuclear Information System (INIS)

    Staerk, E.; Picker, C.; Felsen, M.F.


    Austenitic stainless steels Types 304 and 316 are used for LMFBR components. Although at high temperature many codes base the allowable stress on the stress rupture strength, some recent codes eg ASME Code Case N47 and RCC-MR also take account of the onset of tertiary creep. In order to examine this latter aspect creep deformation data on Type 304 and Type 316 steel have been collected and analysed. The ratio time to onset of tertiary creep against the time to rupture has been analysed as a function of temperature. At temperatures below 750 0 C the ratio is found to decrease slightly with increasing temperature. Monkman Grant and Lambda relationships have also been investigated. In relation to the ASME S t allowable stress criteria it is shown that below 600 0 C the allowable stress is likely to be governed by the stress rupture strength rather than the onset of tertiary creep criterion. Recommendations are given concerning the determination of the onset of tertiary creep, the fitting of the Leyda/Rowe relationship and a method to compute the maximum allowable stress S t from equation describing the time-temperature dependency of the three constituents of S t

  10. Defining English Language Proficiency for Malaysian Tertiary Education: Past, Present and Future Efforts

    Directory of Open Access Journals (Sweden)

    Chan Swee Heng


    Full Text Available Any attempt to define English language proficiency can never be divorced from the theories that describe the nature of language, language acquisition and human cognition. By virtue of such theories being socially constructed, the descriptions are necessarily value-laden. Thus, a definition of language proficiency can only, at best, be described as developmental, following changes that are linguistic, pragmatic, cultural and political. In defining English proficiency for tertiary education, the context is naturally also linked to the focus on university education. The argument has been that an ‘acceptable’ level of language competence of a university applicant is anything but constant. Tremendous social changes have seen traditional values of elitism in university education giving way to the ‘massification’ of education. As Kaplan and Baldauf (1997:257 affirms, “The principal problem in tertiary education is not declining literacy standards but rather it is about meeting changed societal, cultural and informational requirements and circumstances”. In the light of these changes, this paper attempts to trace influencing factors that help define an ‘acceptable’ level of English proficiency for Malaysian tertiary education. The paper examines past and present efforts of establishing an English language policy and assessment practice for tertiary education, and concludes with some views on future development that could evolve from the current indicative pursuits of establishing language learning and ability.
