    Full Text Available Background: Omalizumab is the first and yet the only biopreparation for asthma which combines high efficiency and high cost. The clinical-economic expediency of using omalizumab in asthmatic children has not been previously studied in Russia.Objective: Our aim was to evaluate the clinical and economic expediency of using omalizumab as additive treatment (to basic or supporting therapy in children with severe uncontrolled atopic asthma under the Russian economic conditions.Methods: We conducted a mathematical simulation of asthma treatment in children with an increased frequency of hospitalization (9 times per year with an average monthly omalizumab requirement of 558 mg. The model is based on the Markov chain. The model includes direct and non-direct costs. The planning horizons were 2 and 5 years. We analyzed the efficiency and utility of the costs and their influence on the budget. The stability of received data is proven by sensitivity analyzis.Results: Over a 5-year planning horizon the cost of an additional year of quality life (due to using omalizumab was 1,259,185 roubles, while the “society’s solvency” is 1 341 308 roubles (cost utility analizis. It takes 39,820 rubles to prevent one hospitalization with omalizumab over a 5-year planning horizon (cost efficiency analizis, which is comparable to the cost of hospitalization (43,141 rubles. Total costs for treating 100 children with asthma, 7 of which would be treated with omalizumab, were equal to the amount of money which is enough to treat 105 children without omalizumab (analysis of budgetary influence.Conclusion: The analyses of cost efficiency and utility have shown that the strategy of using omalizumab together with standard treatment is economically expedient. Budgetary influence analysis has not detected a significant burden on the budget.

    Full Text Available Aromatic precursors are precisely in the skin of grapes and nearby cells, and therefore there is a greater expression of the varietal aromas and aromatic precursors when the wine passes through this skin contact, as well as changes in product color. The aim of this study was to evaluate the physical and chemical characteristics of Chardonnay wine that has gone through different periods of skin contact. Chardonnay grapes, grown in vineyards located in the town of Bagé, in Campanha Gaúcha, were de-stemmed, crushed and a sulfur dioxide (50 mg/L−1 was addeded. The experimental design was a 4 × 3 factorial of 4 treatments with 3 repetitions: T1, the wine obtained directly from pressing machine; T2, skin contact for 2 days; T3, skin contact for 4 days and T4, skin contact for 6 days. After the end of malolactic fermentation wines went under − 2∘C for the tartaric stabilization. There were analyzed the variables alcohol, total acidity, volatile acidity, total polyphenols, glycerol, gluconic acid and 420, 520 and 620 colors by infrared spectroscopy method by Fourier transform and the means were compared by 5% Tukey test. There was a significant differencein variables alcohol, volatile acidit, glucanic acid and color index of 420 nm (yellow.

    2008-01-01

    This paper introduces three separation conditions for topological spaces, called T_{0,1}, T_{0,2} ("pre-Hausdorff"), and T_{1,2}. These conditions generalize the classical T_(1) and T_(2) separation axioms, and they have advantages over them topologically which we discuss. We establish several different characterizations of pre-Hausdorff spaces, and a characterization of Hausdorff spaces in terms of pre-Hausdorff. We also discuss some classical Theorems of general topology which can or cannot be generalized by replacing the Hausdorff condition by pre-Hausdorff.

    The Dark Energy Survey (DES) will be taking the next step in probing the properties of Dark Energy and in understanding the physics of cosmic acceleration. A step towards the photometric calibration of DES is to have a quick, bright survey in the DES footprint (PreCam), using a pre-production set of the Dark Energy Camera (DECam) CCDs and a set of 100 mm×100 mm DES filters. The objective of the PreCam Survey is to create a network of calibrated DES grizY standard stars that will be used for DES nightly calibrations and to improve the DES global relative calibrations. Here, we describe the first year of PreCam observation, results, and photometric calibrations.

    Pre-eclampsia affects 3-5% of pregnancies and is traditionally diagnosed by the combined presentation of high blood pressure and proteinuria. New definitions also include maternal organ dysfunction, such as renal insufficiency, liver involvement, neurological or haematological complications, uteroplacental dysfunction, or fetal growth restriction. When left untreated, pre-eclampsia can be lethal, and in low-resource settings, this disorder is one of the main causes of maternal and child mortality. In the absence of curative treatment, the management of pre-eclampsia involves stabilisation of the mother and fetus, followed by delivery at an optimal time. Although algorithms to predict pre-eclampsia are promising, they have yet to become validated. Simple preventive measures, such as low-dose aspirin, calcium, and diet and lifestyle interventions, show potential but small benefit. Because pre-eclampsia predisposes mothers to cardiovascular disease later in life, pregnancy is also a window for future health. A collaborative approach to discovery and assessment of the available treatments will hasten our understanding of pre-eclampsia and is an effort much needed by the women and babies affected by its complications.

    Objective An attempt to define pre-osteoarthritis (OA) versus early OA and definitive osteoarthritis. Methods A group of specialists in the field of cartilage science and treatment was formed to consider the nature of OA onset and its possible diagnosis. Results Late-stage OA, necessitating total joint replacement, is the end stage of a biological process, with many previous earlier stages. Early-stage OA has been defined and involves structural changes identified by arthroscopy or radiography. The group argued that before the “early-stage OA” there must exist a stage where cellular processes, due to the presence of risk factors, have kicked into action but have not yet resulted in structural changes. The group suggested that this stage could be called “pre-osteoarthritis” (pre-OA). Conclusions The group suggests that defining points of initiation for OA in the knee could be defined, for example, by traumatic episodes or surgical meniscectomy. Such events may set in motion metabolic processes that could be diagnosed by modern MRI protocols or arthroscopy including probing techniques before structural changes of early OA have developed. Preventive measures should preferably be applied at this pre-OA stage in order to stop the projected OA “epidemic.” PMID:26175861

    2008-01-01

    How can an action to a target be selected without yet knowing what it is? Pre-emptive perception (PEP) is a framework which orders neuronal mechanisms in association with voluntary actions before an action is started and until it is completed. It is assumed that PEP serves the purpose of perception, but a conscious, perceptual identification of the goal is not obligatorily completed during the time period of PEP itself. The concept of PEP is that the brain pre-emptively optimizes an action plan to maximize eventual perception, even before being sure what the goal is. Experimental studies of voluntary saccadic eye movements are considered as prototypic activity within the framework of PEP. The core concept of pre-emption is that a particular saccade is selected while a large number of other possible actions are deselected. Pre-emptive computations include mechanisms associated with internal context and reward. Neurophysiological studies which show anatomically and functionally separate cortical and some subcortical neuronal groups in computing saccades are summarized. There is a potential relationship of PEP as a neurobiological framework and some philosophical concepts. Terms for processes between planning and action, such as intention, anticipation, and attention, are often incongruent in everyday language and in epistemology. It is proposed here that a scrutiny of these terms can be rigorously approached by temporal subdivision of PEP and conversely, clear definitions of these terms can lead to organized experimental designs of cognitive neurobiology. The temporal subdivision of PEP allows a critique of The Will in the definition of Schopenhauer and distinguishes it from the 'free will'.

  13. Pre-operative anaemia.

    Clevenger, B; Richards, T

    2015-01-01

    Pre-operative anaemia is a relatively common finding, affecting a third of patients undergoing elective surgery. Traditionally associated with chronic disease, management has historically focused on the use of blood transfusion as a solution for anaemia in the peri-operative period. Data from large series now suggest that anaemia is an independent risk associated with poor outcome in both cardiac and non-cardiac surgery. Furthermore, blood transfusion does not appear to ameliorate this risk, and in fact may increase the risk of postoperative complications and hospital length of stay. Consequently, there is a need to identify, diagnose and manage pre-operative anaemia to reduce surgical risk. Discoveries in the pathways of iron metabolism have found that chronic disease can cause a state of functional iron deficiency leading to anaemia. The key iron regulatory protein hepcidin, activated in response to inflammation, inhibits absorption of iron from the gastrointestinal tract and further reduces bioavailability of iron stores for red cell production. Consequently, although iron stores (predominantly ferritin) may be normal, the transport of iron either from the gastrointestinal tract or iron stores to the bone marrow is inhibited, leading to a state of 'functional' iron deficiency and subsequent anaemia. Since absorption from the gastrointestinal tract is blocked, increasing oral iron intake is ineffective, and studies are now looking at the role of intravenous iron to treat anaemia in the surgical setting. In this article, we review the incidence and impact of anaemia on the pre-operative patient. We explain how anaemia may be caused by functional iron deficiency, and how iron deficiency anaemia may be diagnosed and treated.

    Full Text Available This study explored the impact of a reflective teaching method on pre-service elementary teachers’ conceptual understanding of the lunar phases, reasons for seasons, and simple electric circuits. Data were collected from 40 pre-service elementary teachers about their conceptual understanding of the lunar phases, reasons for seasons and day and night, and simple electric circuits pre and post instruction. Findings show that the instructional approach adopted by a science teacher educator had a significant impact on pre-serviceelementary school teachers’ conceptual understanding of lunar phases, seasonal changes and simple electric circuits. The discussion focuses on pre-service elementary school teachers’ misconceptions about the lunar phases, seasonal changes and simple electric circuits as revealed through their answers to the pre-test questions. Further discussion focuses on the implications of the findings for pre-service elementary school science teacher education.

    The human skin provides a habitat for a variety of microorganisms, the skin microflora. There is a complex network of interactions between the microbes and cells of the epidermis. Modern analytical methods in molecular biology have revealed new insights into this complex diversity of partially unculturable microbial organisms. Most of the resident microbes on healthy skin can be regarded as being harmless or even beneficial to skin. In the case of diseases with some imbalance in microorganisms, such as impure skin/mild acne or dry skin/mild atopic dermatitis, pre- and probiotic concepts represent an effective alternative to strictly antibacterial products. Prebiotic actives rebalance the skin microflora while probiotic approaches predominantly consist of applying an inactivated microbial biomass of beneficial bacteria. Several examples of successful in vivo studies illustrate this new principle for gentle cosmetics derived from the food sector.

    Pre-hospital care is emergency medical care given to patients before arrival in hospital after activation of emergency medical services. It traditionally incorporated a breadth of care from bystander resuscitation to statutory emergency medical services treatment and transfer. New concepts of care including community paramedicine, novel roles such as emergency care practitioners, and physician delivered pre-hospital emergency medicine are re-defining the scope of pre-hospital care. For severely ill or injured patients, acting quickly in the pre-hospital period is crucial with decisions and interventions greatly affecting outcomes. The transfer of skills and procedures from hospital care to pre-hospital medicine enables early advanced care across a range of disciplines. The variety of possible pathologies, challenges of environmental factors, and hazardous situations requires management that is tailored to the patient's clinical need and setting. Pre-hospital clinicians should be generalists with a broad understanding of medical, surgical, and trauma pathologies, who will often work from locally developed standard operating procedures, but who are able to revert to core principles. Pre-hospital emergency medicine consists of not only clinical care, but also logistics, rescue competencies, and scene management skills (especially in major incidents, which have their own set of management principles). Traditionally, research into the hyper-acute phase (the first hour) of disease has been difficult, largely because physicians are rarely present and issues of consent, transport expediency, and resourcing of research. However, the pre-hospital phase is acknowledged as a crucial period, when irreversible pathology and secondary injury to neuronal and cardiac tissue can be prevented. The development of pre-hospital emergency medicine into a sub-specialty in its own right should bring focus to this period of care.

    Pre-eclampsia, formerly called pregnancy-induced hypertension, refers to the new onset of hypertension (SBP > or = 140 mmHg or DBP > or = 90 mmHg) and proteinuria (> or = 0.3 g protein in a 24-hour urine specimen or 1+ on dipstick) after 20 weeks of gestation in a previously normotensive women. It is a life-threatening, multi-organ involvement disease and remains the leading cause of maternal death. Its clinical manifestations are the result of generalized vasospasm, activation of the coagulation system, and changes in several humoral and autoregulatory systems related to volume and blood pressure control. Pre-eclampsia is responsible for high perinatal mortality and morbidity rates, primarily due to early termination of pregnancy. Fetus growth restriction, oligohyrdramnios and non-reassuring fetal status are the consequences of chronic placental hypoperfusion. Pre-eclampsia does not appear to accelerate fetal maturation, as once believed. Delivery remains the definitive treatment of choice for pre-eclampsia and should be timely. Cesarean section is not necessary and reserved for the obstetrical indications only. The expectant management may be considered for women remote from term (< 32 to 34 weeks of gestation) with stable and uncomplicated severe disease. The supportive management such as blood pressure control, seizure prevention, and fetal well-being assessment are also important to ensure the satisfactory outcome. To date, no screening test has been proved to be reliable and cost-effective. The prevention of pre-eclampsia with antioxidant therapy (vitamin C, E) has shown promise, but large, randomized trials are needed. Although controversy exists, calcium supplementation has shown no benefit in large trials, and most evidence suggests little or no benefit for low-dose aspirin as prevention in women in the low-risk category.

    Pre-existence probability of the fragments for the complete binary spectrum of different systems such as {sup 56}Ni, {sup 116}Ba, {sup 226}Ra and {sup 256}Fm are calculated, from the overlapping part of the interaction potential using the WKB approximation. The role of reduced mass as well as the classical hydrodynamical mass in the WKB method is analysed. Within WKB, even for negative Q -value systems, the pre-existence probability is calculated. The calculations reveal rich structural information. The calculated results are compared with the values of preformed cluster model of Gupta and collaborators. The mass asymmetry motion is shown here for the first time as a part of relative separation motion. (orig.)

    Full Text Available This report on a male head revealed biologic rhythms, as gleaned from hydrogen isotope ratios in hair, consistent with a South-American origin and Atomic Mass Spectrometry radiocarbon dating (AMS compatible with the last pre-Hispanic period (1418-1491 AD, 95.4% probability. Biopsies showed exceptionally well-preserved tissues. The hair contained high levels of toxic elements (lead, arsenic and mercury incompatible with life. There was no evidence for lead deposition in bone consistent with post-mortem accumulation of this toxic element in the hair. We propose that the high content of metals in hair was the result of metabolic activity of bacteria leading to metal complexation in extra cellular polymeric substances (EPS. This is a recognized protective mechanism for bacteria that thrive in toxic environments. This mechanism may account for the tissues preservation and gives a hint at soil composition where the head was presumably buried. Our results have implications for forensic toxicology which has, hitherto, relied on hair analyses as one means to reconstruct pre-mortem metabolism and for detecting toxic elements accumulated during life. Our finding also has implications for other archaeological specimens where similar circumstances may distort the results of toxicological studies.

    2012-01-31

    Pre-eclampsia (P-EC) is a multisystem disorder exclusive to pregnancy. It complicates ~2 to 8% of all pregnancies and remains a major cause of maternal mortality. P-EC is characterized by a profound hypercoagulable state. The delicate hemostatic balance that must be maintained in the uteroplacental circulation during pregnancy makes this system vulnerable to perturbation.

    Pre-eclampsia (P-EC) is a multisystem disorder exclusive to pregnancy. It complicates ~2 to 8% of all pregnancies and remains a major cause of maternal mortality. P-EC is characterized by a profound hypercoagulable state. The delicate hemostatic balance that must be maintained in the uteroplacental circulation during pregnancy makes this system vulnerable to perturbation. An abnormal hemostatic pattern occurs within the uteroplacental circulation in P-EC compared with normal pregnancy. Much recent research has focused on the epidemiological link between inherited thrombophilia and P-EC. The data suggest a weak statistical association, indicating an improbable primary role in the pathogenesis.

    1997-01-01

    On Sol 39 there were wispy blue clouds in the pre-dawn sky of Mars, as seen by the Imager for Mars Pathfinder (IMP). The color image was made by taking blue, green, and red images and then combining them into a single color image. The clouds appear to have a bluish side and a greenish side because they moved (in the wind from the northeast) between images. This picture was made an hour and twenty minutes before sunrise -- the sun is not shining directly on the water ice clouds, but they are illuminated by the dawn twilight.Mars Pathfinder is the second in NASA's Discovery program of low-cost spacecraft with highly focused science goals. The Jet Propulsion Laboratory, Pasadena, CA, developed and manages the Mars Pathfinder mission for NASA's Office of Space Science, Washington, D.C. JPL is a division of the California Institute of Technology (Caltech). The Imager for Mars Pathfinder (IMP) was developed by the University of Arizona Lunar and Planetary Laboratory under contract to JPL. Peter Smith is the Principal Investigator.

  18. Pre-equilibrium plasma dynamics

    Energy Technology Data Exchange (ETDEWEB)

    Heinz, U.

    1986-01-01

    Approaches towards understanding and describing the pre-equilibrium stage of quark-gluon plasma formation in heavy-ion collisions are reviewed. Focus is on a kinetic theory approach to non-equilibrium dynamics, its extension to include the dynamics of color degrees of freedom when applied to the quark-gluon plasma, its quantum field theoretical foundations, and its relationship to both the particle formation stage at the very beginning of the nuclear collision and the hydrodynamic stage at late collision times. The usefulness of this approach to obtain the transport coefficients in the quark-gluon plasma and to derive the collective mode spectrum and damping rates in this phase are discussed. Comments are made on the general difficulty to find appropriated initial conditions to get the kinetic theory started, and a specific model is given that demonstrates that, once given such initial conditions, the system can be followed all the way through into the hydrodynamical regime. 39 refs., 7 figs.

    1998-03-01

    Sandia National Laboratories` Product Realization Environment (PRE) is a lightweight, CORBA based framework for the integration of a broad variety of applications. These applications are wrapped for use in the PRE framework as reusable components. For example, some of the PRE components currently available include: (1) product data management (PDM) system, (2) human resources database, several finite element analysis programs, and (3) a variety of image and document format converters. PRE enables the development of end user applications (as Java applets, for example) that use these components as building blocks. To aid such development, the PreLib library (available in both C++ and Java) permits both wrapping and using these components without knowledge of either CORBA or the security mechanisms used.

    2015-12-01

    The purpose of this study was to investigate the effects of pre-task music on swimming performance and other psychological variables. A randomized counterbalanced within-subjects (experimental and control condition) design was employed. Eighteen regional level male swimmers performed two 200-m freestyle swimming time trials. Participants were exposed to either 5 minutes of self-selected music (pre-task music condition) or 5 minutes of silence (control condition) and, after 1 minute, performed the swimming task. Swimming time was significantly shorter (-1.44%) in the pre-task music condition. Listening to pre-task music increased motivation to perform the swimming task, while arousal remained unchanged. While fatigue increased after the swimming task in both conditions, vigor, ratings of perceived exertion and affective valence were unaltered. It is concluded, for the first time, that pre-task music improves swimming performance.

    2007-01-01

    , 32 women developed pre-eclampsia, and 5 controls for every case of pre-eclampsia were found. Blood samples were collected 4 times and urine samples 6 times from the 18/19th week and throughout pregnancy. Orosomucoid and albumin in plasma were analysed by standard methods, and in urine by sandwich...... in orosomucoid. In the plasma samples, orosomucoid was significantly higher late in pre-eclamptic pregnancies (>or=36th week, p=0.0275). CONCLUSIONS: Pre-eclampsia is associated with a pre-symptomatic increase in the urine excretion of orosomucoid, and orosomucoid excretion precedes that of albumin. Orosomucoid...... excretion can probably be used as a prognostic tool in combination with other screening methods, and seems to be a more sensitive marker for evolving pre-eclampsia than albumin. Plasma orosomucoid is significantly increased late in pre-eclampsia. Thus, the increased excretion of orosomucoid must primarily...

  11. Understanding Pre-Quantitative Risk in Projects

    Science.gov (United States)

    Cooper, Lynne P.

    2011-01-01

    Standard approaches to risk management in projects depend on the ability of teams to identify risks and quantify the probabilities and consequences of these risks (e.g., the 5 x 5 risk matrix). However, long before quantification does - or even can - occur, and long after, teams make decisions based on their pre-quantitative understanding of risk. These decisions can have long-lasting impacts on the project. While significant research has looked at the process of how to quantify risk, our understanding of how teams conceive of and manage pre-quantitative risk is lacking. This paper introduces the concept of pre-quantitative risk and discusses the implications of addressing pre-quantitative risk in projects.

    Full Text Available ABSTRACT Dental composites cured at high temperatures show improved properties and higher degrees of conversion; however, there is no information available about the effect of pre-heating on material degradation. Objectives This study evaluated the effect of pre-heating on the degradation of composites, based on the analysis of radiopacity and silver penetration using scanning electron microscopy/energy-dispersive X-ray spectroscopy (SEM/EDS. Material and Methods Thirty specimens were fabricated using a metallic matrix (2x8 mm and the composites Durafill VS (Heraeus Kulzer, Z-250 (3M/ESPE, and Z-350 (3M/ESPE, cured at 25°C (no pre-heating or 60°C (pre-heating. Specimens were stored sequentially in the following solutions: 1 water for 7 days (60°C, plus 0.1 N sodium hydroxide (NaOH for 14 days (60°C; 2 50% silver nitrate (AgNO3 for 10 days (60°C. Specimens were radiographed at baseline and after each storage time, and the images were evaluated in gray scale. After the storage protocol, samples were analyzed using SEM/EDS to check the depth of silver penetration. Radiopacity and silver penetration data were analyzed using ANOVA and Tukey’s tests (α=5%. Results Radiopacity levels were as follows: Durafill VSZ-350>Z-250 (p<0.05. After storage in water/NaOH, pre-heated specimens presented higher radiopacity values than non-pre-heated specimens (p<0.05. There was a lower penetration of silver in pre-heated specimens (p<0.05. Conclusions Pre-heating at 60°C mitigated the degradation of composites based on analysis of radiopacity and silver penetration depth.

  17. Pre-Flare Flows in the Corona

    Solar flares take place in regions of strong magnetic fields and are generally accepted to be the result of a resistive instability leading to magnetic reconnection. When new flux emerges into a pre-existing active region it can act as a flare and coronal mass ejection trigger. In this study we observed active region 10955 after the emergence of small-scale additional flux at the magnetic inversion line. We found that flaring began when additional positive flux levels exceeded 1.38×1020 Mx (maxwell), approximately 7 h after the initial flux emergence. We focussed on the pre-flare activity of one B-class flare that occurred on the following day. The earliest indication of activity was a rise in the non-thermal velocity one hour before the flare. 40 min before flaring began, brightenings and pre-flare flows were observed along two loop systems in the corona, involving the new flux and the pre-existing active region loops. We discuss the possibility that reconnection between the new flux and pre-existing loops before the flare drives the flows by either generating slow mode magnetoacoustic waves or a pressure gradient between the newly reconnected loops. The subsequent B-class flare originated from fast reconnection of the same loop systems as the pre-flare flows.

    Objective. To examine the relationship between the NAPLEX and Pre-NAPLEX among pharmacy graduates, as well as determine effects of pre-pharmacy, pharmacy school, and demographic variables on NAPLEX performance. Methods. A retrospective review of pharmacy graduates' NAPLEX scores, Pre-NAPLEX scores, demographics, pre-pharmacy academic performance factors, and pharmacy school academic performance factors was performed. Bivariate (eg, ANOVA, independent samples t-test) and correlational analyses were conducted, as was stepwise linear regression to examine the significance of Pre-NAPLEX score and other factors as related to NAPLEX score. Results. One hundred fifty graduates were included, with the majority being female (60.7%) and white (72%). Mean NAPLEX score was 104.7. Mean Pre-NAPLEX score was 68.6. White students had significantly higher NAPLEX scores compared to Black/African American students. NAPLEX score was correlated to Pre-NAPLEX score, race/ethnicity, PCAT composite and section scores, undergraduate overall and science GPAs, pharmacy GPA, and on-time graduation. The regression model included pharmacy GPA and Pre-NAPLEX score. Conclusion. The findings provide evidence that, although pharmacy GPA is the most critical determinant, the Pre-NAPLEX score is also a significant predictor of NAPLEX score.

    2016-08-24

    Pre-eclampsia is a multisystem disorder with incidence rates ranging from 2% to 5%. Hyponatraemia is a rare complication of pre-eclampsia. A 41-year-old, para 0+1 in vitro fertilisation monochorionic diamniotic triplet pregnancy woman presented at 25 weeks with dyspnoea and general malaise. Her antenatal course was complicated by the diagnosis of intrauterine growth restriction in triplet one at 27 weeks of gestation. At 27+3 weeks gestation, she was diagnosed as having pre-eclampsia. Subsequent biochemical analysis demonstrated hyponatraemia with serum sodium falling steadily to 117 mmol/L over the next 19 days. She was admitted to intensive care unit for stabilisation of fulminant pre-eclampsia and severe hyponatraemia at 30+5 weeks of gestation. Hypertonic saline and intravenous labetolol were administered prior to delivery by caesarean section. She recovered well postdelivery with stabilisation of her blood pressure and normalisation of her sodium level to 135 mmol/L. Awareness and frequent monitoring of hyponatraemia should become an integral part of monitoring women with pre-eclampsia.

    Studies of pre-eclampsia and childhood asthma are conflicting, and none have performed a formal mediation analysis of preterm birth.We examined the association between pre-eclampsia and asthma at 7 years using national registries, including all births in Norway from 1999 to 2006 (n=406 907), and a subsample of children in the Norwegian Mother and Child Cohort Study (MoBa) (n=45 028) using log-linear regression. We performed a mediation analysis of preterm birth, and a sibling comparison to evaluate unobserved confounding.There was a positive association between pre-eclampsia and asthma in the registry study, with an adjusted relative risk of 1.31 (95% CI 1.22-1.41), but not in MoBa, which had an adjusted relative risk of 1.19 (95% CI 0.99-1.44). The odds ratios for the direct effect not mediated through preterm birth and the indirect effect in the registry linkage were 1.19 (95% CI 1.10-1.29) and 1.12 (95% CI 1.11-1.14), respectively. The sibling comparison indicated no association between pre-eclampsia and asthma (adjusted OR 1.07, 95% CI 0.87-1.33).In this large study, which used different datasets and analytic approaches, there was little evidence for an association between pre-eclampsia and childhood asthma. The association was weak and largely explained by pre-term birth and confounders shared by siblings.

    Full Text Available Pre-anaesthetic screening has been advocated as a valuable tool for improving anaesthetic safety and determining anaesthetic risk. This study was done determine whether pre-anaesthetic screening result in cancellation of anaesthesia and the diagnosis of new clinical conditions in geriatric dogs. One hundred and one dogs older than 7 years of age provided informed owner consent were included in the study. Each dog was weighed, and its temperature, pulse and respiration recorded. An abdominal palpation, examination of the mouth, including capillary refill time and mucous membranes, auscultation, body condition and habitus was performed and assessed. A cephalic catheter was placed and blood drawn for pre-anaesthetic testing. A micro-haematocrit tube was filled and the packed cell volume determined. The blood placed was in a test tube, centrifuged and then analysed on an in-house blood analyser. Alkaline phosphatase, alanine transferase, urea, creatinine, glucose and total protein were determined. A urine sample was then obtained by cystocentesis, catheterisation or free-flow for analysis. The urine specific gravity was determined with a refractometer. A small quantity of urine was then placed on a dip stick. Any new diagnoses made during the pre-anaesthetic screening were recorded. The average age of the dogs was 10.99+2.44 years and the weight was 19.64+15.78 kg. There were 13 dogs with pre-existing medical conditions. A total of 30 new diagnoses were made on the basis of the pre-anaesthetic screening. The most common conditions were neoplasia, chronic kidney disease and Cushing's disease. Of the 30 patients with a new diagnosis, 13 did not undergo anaesthesia as result of the new diagnosis. From this study it can be concluded that screening of geriatric patients is important and that sub-clinical disease could be present in nearly 30 % of these patients. The value of screening before anaesthesia is perhaps more questionable in terms of

    The Advanced CANDU Reactor (ACR) is an evolutionary advancement of the current CANDU 6 reactor, aimed at producing electrical power for a capital cost and at a unit-energy cost significantly less than that of the current reactor designs. The Canadian Nuclear Safety Commission (CNSC) staff are currently reviewing the ACR design to determine whether, in their opinion, there are any fundamental barriers that would prevent the licensing of the design in Canada. This CNSC licensability review will not constitute a licence, but is expected to reduce regulatory risk. The CNSC pre-licensing review started in September 2003, and was focused on identifying topics and issues for ACR-700 that will require a more detailed review. CNSC staff reviewed about 120 reports, and issued to AECL 65 packages of questions and comments. Currently CNSC staff is reviewing AECL responses to all packages of comments. AECL has recently refocused the design efforts to the ACR-1000, which is a larger version of the ACR design. During the remainder of the pre-licensing review, the CNSC review will be focused on the ACR-1000. AECL Technologies Inc. (AECLT), a wholly-owned US subsidiary of AECL, is engaged in a pre-application process for the ACR-700 with the US Nuclear Regulatory Commission (USNRC) to identify and resolve major issues prior to entering a formal process to obtain standard design certification. To date, the USNRC has produced a Pre-Application Safety Assessment Report (PASAR), which contains their reviews of key focus topics. During the remainder of the pre-application phase, AECLT will address the issues identified in the PASAR. Pursuant to the bilateral agreement between AECL and the Chinese nuclear regulator, the National Nuclear Safety Administration (NNSA) and its Nuclear Safety Center (NSC), NNSA/NSC are reviewing the ACR in seven focus areas. The review started in September 2004, and will take three years. The main objective of the review is to determine how the ACR complies

    Pre-eclampsia is a multi-system condition in pregnancy that is characterised by the onset of hypertension and proteinuria in women after the 20th week and it remains a leading cause of maternal and fetal mortality. Despite this the causative molecular basis of pre-eclampsia remains poorly understood. As a result, an intensive research effort has focused on understanding the molecular mechanisms involved in pre-eclampsia and using this information to identify new pre-symptomatic bio-markers of the condition. Activin A and its receptor, ACVR2A, have been extensively studied in this regard. Activin A is a member of the transforming growth factor (TGF)-β superfamily that has a wide range of biological functions depending on the cellular context. Recent work has shown that polymorphisms in ACVR2A may be a genetic risk factor for pre-eclampsia. Furthermore, both placenta and serum levels of Activin A are significantly increased in pre-eclampsia suggesting that Activin A may be a possible biomarker for the condition. Here we review the latest advances in this field and link these with new molecular data that suggest that the oxidative stress and pro-inflammatory cytokine production seen in pre-eclampsia may result in increased placental Activin A secretion in an attempt to maintain placental function.

    Dental composites cured at high temperatures show improved properties and higher degrees of conversion; however, there is no information available about the effect of pre-heating on material degradation. Objectives This study evaluated the effect of pre-heating on the degradation of composites, based on the analysis of radiopacity and silver penetration using scanning electron microscopy/energy-dispersive X-ray spectroscopy (SEM/EDS). Material and Methods Thirty specimens were fabricated using a metallic matrix (2x8 mm) and the composites Durafill VS (Heraeus Kulzer), Z-250 (3M/ESPE), and Z-350 (3M/ESPE), cured at 25°C (no pre-heating) or 60°C (pre-heating). Specimens were stored sequentially in the following solutions: 1) water for 7 days (60°C), plus 0.1 N sodium hydroxide (NaOH) for 14 days (60°C); 2) 50% silver nitrate (AgNO3) for 10 days (60°C). Specimens were radiographed at baseline and after each storage time, and the images were evaluated in gray scale. After the storage protocol, samples were analyzed using SEM/EDS to check the depth of silver penetration. Radiopacity and silver penetration data were analyzed using ANOVA and Tukey's tests (α=5%). Results Radiopacity levels were as follows: Durafill VSZ-350>Z-250 (pheated specimens presented higher radiopacity values than non-pre-heated specimens (pheated specimens (pheating at 60°C mitigated the degradation of composites based on analysis of radiopacity and silver penetration depth.

  10. Stress responses and pre-eclampsia.

    Science.gov (United States)

    Redman, C W G

    2013-04-01

    Biological stress may affect individual cells, tissues or whole organisms, arising from disturbed homoeostasis of any cause. Stress is rarely localised. Because biological systems are closely integrated, it spreads to involve other systems. Stress responses are highly integrated and work to restore homoeostasis. Different response pathways overlap and interlink. If the responses fail or decompensate, distress ensues, of which the end-stage is death. Pre-eclampsia results from a series of biological stresses, possibly from conception, which become established by abnormal placentation and affect the mother, her foetus and her placenta. The stresses involve dialogue between mother and placenta. Even a normal placenta imposes substantial stress on maternal systems. When placental growth and perfusion is abnormal (poor placentation) then the placenta, particularly its outer trophoblast layer, becomes stressed - loosely denoted hypoxic damage or oxidative stress. Signals from the placenta spread the stress to the mother, who develops signs of pre-eclampsia. Cellular stress sensors initiate stress responses. Different stresses may trigger similar responses in specific cell types. The first cell response is reduced protein synthesis. However some synthetic pathways are spared or activated to produce stress signals. In relation to pre-eclampsia and the placenta, an excessive release of sFlt-1 a soluble decoy receptor for vascular endothelial growth factor (VEGF) is a trophoblast related stress signal. SFlt1 perturbs the angiogenic balance in the maternal circulation and is considered to cause many of the specific features of the maternal syndrome in pre-eclampsia. Three key points will be emphasised. First, multiple stressors, not simply hypoxia, stimulate the release of sFlt-1 from trophoblast. Second, sFlt-1 is only one of the group of stress signals delivered by trophoblast to the mother. Third, sFlt-1 is not the only trophoblast derived factor to perturb the maternal

    Pre-operative anaemia is common and occurs in up to 76% of patients. It is associated with increased peri-operative allogeneic blood transfusions, longer hospital lengths of stay and increased morbidity and mortality. Iron deficiency is one of the most common causes of this anaemia. Oral iron therapy has traditionally been used to treat anaemia but newer, safer parenteral iron preparations have been shown to be more effective in other conditions such as inflammatory bowel disease, chronic heart failure and post-partum haemorrhage. A limited number of studies look at iron therapy for the treatment of pre-operative anaemia. The aim of this Cochrane review is to summarise the evidence for use of iron supplementation, both enteral and parenteral, for the management of pre-operative anaemia. The objective of this review is to evaluate the effects of pre-operative iron therapy (enteral or parenteral) in reducing the need for allogeneic blood transfusions in anaemic patients undergoing surgery. We ran the search on 25 March 2015. We searched the Cochrane Injuries Group's Specialised Register, Cochrane Central Register of Controlled Trials (CENTRAL, The Cochrane Library), Ovid MEDLINE(R), Ovid MEDLINE(R) In-Process & Other Non-Indexed Citations, Ovid MEDLINE(R) Daily and Ovid OLDMEDLINE(R), EMBASE Classic and EMBASE (Ovid), CINAHL Plus (EBSCO), PubMed, clinical trials registries, conference abstracts, and we screened reference lists. We included all randomised controlled trials (RCTs) which compared pre-operative iron monotherapy to placebo, no treatment, standard of care or another form of iron therapy for anaemic adults undergoing surgery. Anaemia was defined by haemoglobin values less than 13 g/dL for males and 12 g/dL for non-pregnant females. Data were collected by two authors on the proportion of patients who receive a blood transfusion, amount of blood transfused per patient (units) and haemoglobin measured as continuous variables at pre-determined time-points: pre

    Pre-eclampsia is a multisystem disorder of pregnancy usually associated with raised blood pressure (BP) and proteinuria. The pathogenesis is not understood despite decades of research. Abnormal placentation related to immune mechanisms and maladaptation of the placenta may be the first step in the development of the disease. Although there are a number of risk factors and new innovatory tests (e.g., uterine artery Doppler) which can be used to predict pre-eclampsia, none fulfils standard diagnostic criteria. Of possible prophylactic value are antiplatelet agents, calcium supplementation and vitamins C and E. Prevention of eclampsia with magnesium sulfate is the subject of a current international randomised controlled trial (RCT), known as MAGPIE. Therapeutic strategies include avoidance of hypertensive injury and delivery of the baby and placenta. Further research into specific antihypertensive agents and conservative management strategies is required.

    Full Text Available The success of an epilepsy surgery program depends upon the early identification of potential surgical candidates and selecting from them, ideal candidates for surgery, who are destined to have a post-operative seizure-free outcome without any unacceptable neurological deficits. Since epilepsy surgery centers in resource-poor countries will lack the full range of state-of-the-art technologies usually available in resource-rich countries to perform pre-surgical evaluation, cost-effectively utilization of the locally available investigative facilities to select the surgical candidates becomes challenging. In the present era of rapid electronic communications and telemedicine, it has become possible for epilepsy surgery centers to pool their technological and human resources and to partner with centers nationally and internationally in implementing pre-surgical evaluation strategies.

    "We present 2 - 2.4 micron integral-field spectroscopy, using Gemini NIFS, of a sample of hot post-AGB stars with early B spectral types. These stars are just starting to ionize their environments and turn into planetary nebulae (PN). Unlike in the earlier dusty pre-PN phase, where outflow morphology is often visible in dust-scattered light, these hot post-AGB stars do not generally reveal their envelope structure in near-IR continuum emission, which is dominated by the bright central star. Instead we use molecular hydrogen emission lines to study the asymmetrical envelopes of these objects and atomic hydrogen and helium recombination lines to probe the extent and shape of the developing ionized region. This combination provides a unique snapshot as the ionization front propagates into the already-shaped pre-PN molecular material, just at the transition point where the new PN is emerging."

    2011-04-01

    Full Text Available Inclusive education is a rational concept that refers to the overall and long-term transformation of institutional systems in society, especially in education. Along with the transformation, a number of important and unresolved issues still appear in both theory and practice, as the duty of pre-school institutions and schools is to educate every student in the mainstream education system. One of the most important aspects of inclusion is the inclusive culture. Regardless of the good inclusive policy and practice, one cannot talk about successful inclusion without a properly developed inclusive institutional culture.This paper is a contribution to the research considering the development of inclusive culture in three preschool institutions. It is based on the thinking and attitudes of the pre­school staff toward the necessity of developing and nurturing an inclusive culture. Successful inclusion of pupils with special needs in the mainstream school system cannot be conceived without an inclusive culture.

    Full Text Available As in other parts of Amazonia, pre-Columbian Indians have profoundly modified the coast of the Guianas. Between 650 and 1650 AD, Arauquinoid people occupied a territory that was approximately 600 km long and used the raised field technique intensively before the European conquest. They erected thousands of raised fields of various shapes, dug canals, ditches, and pathways, and built artificial mounds to establish their villages. All these earthworks changed forever the face of the coastal flooded savannas and their ecology. Such labor was probably organized under the leadership of a central authority: it seems that Arauquinoid societies were organized in a chiefdom system. Statistical calculations, based on the known surface area of raised fields and on their estimated productivity, suggest a population density of 50 to 100 inhabitants per km2. Pre-Columbian inhabitants of the Guianas coast carefully organized, managed and “anthropisized” their territory following a specific pattern.

    Purpose: To compare the pre- and postoperative MR appearance of craniopharyngiomas with respect to lesion size, tumour morphology and identification of surrounding normal structures. Material and Methods: MR images obtained prior to and following craniopharyngioma resection were evaluated retrospectively in 10 patients. Tumour signal charcteristics, size and extension with particular reference to the optic chiasm, the pituitary gland, the pituitary stalk and the third ventricle were evaluated. Results: Following surgery, tumour volume was reduced in all patients. In 6 patients there was further tumour volume reduction between the first and second postoperative images. Two of these patients received radiation therapy between the 2 postoperative studies, while 4 had no adjuvant treatment to the surgical intervention. There was improved visualization of the optic chiasm, in 3, the pituitary stalk in one, and the third ventricle in 9 of the 10 patients. The pituitary gland was identified preoperatively only in one patient, postoperatively only in another, pre- and postoperatively in 5, and neither pre- nor postoperatively in 3 patients. In 3 patients MR imaging 0-7 days postoperatively identified tumour remnants not seen at the end of the surgical procedure. The signal intensities of solid and cystic tumour components were stable from pre- to the first postoperative MR images. Optic tract increased signal prior to surgery was gone 28 days postoperatively in one patient, but persisted on the left side for 197 days after surgery in another. Conclusion: Postoperative MR imaging of craniopharyngiomas demonstrated tumour volume reduction and tumour remnants not seen at surgery. Early postoperative MR imaging of craniopharyngiomas may overestimate the size of residual tumour. Improved visualization of peritumoral structures may be achieved. (orig.).

  2. Speciation without Pre-Defined Fitness Functions.

    Gras, Robin; Golestani, Abbas; Hendry, Andrew P; Cristescu, Melania E

    2015-01-01

    The forces promoting and constraining speciation are often studied in theoretical models because the process is hard to observe, replicate, and manipulate in real organisms. Most models analyzed to date include pre-defined functions influencing fitness, leaving open the question of how speciation might proceed without these built-in determinants. To consider the process of speciation without pre-defined functions, we employ the individual-based ecosystem simulation platform EcoSim. The environment is initially uniform across space, and an evolving behavioural model then determines how prey consume resources and how predators consume prey. Simulations including natural selection (i.e., an evolving behavioural model that influences survival and reproduction) frequently led to strong and distinct phenotypic/genotypic clusters between which hybridization was low. This speciation was the result of divergence between spatially-localized clusters in the behavioural model, an emergent property of evolving ecological interactions. By contrast, simulations without natural selection (i.e., behavioural model turned off) but with spatial isolation (i.e., limited dispersal) produced weaker and overlapping clusters. Simulations without natural selection or spatial isolation (i.e., behaviour model turned off and high dispersal) did not generate clusters. These results confirm the role of natural selection in speciation by showing its importance even in the absence of pre-defined fitness functions.

  3. Rotational inhomogeneities from pre-big bang?

    CERN Document Server

    Giovannini, Massimo

    2005-01-01

    The evolution of the rotational inhomogeneities is investigated in the specific framework of four-dimensional pre-big bang models. While minimal (dilaton-driven) scenarios do not lead to rotational fluctuations, in the case of non-minimal (string-driven) models, fluid sources are present in the pre-big bang phase. The rotational modes of the geometry, coupled to the divergenceless part of the velocity field, can then be amplified depending upon the value of the barotropic index of the perfect fluids. In the light of a possible production of rotational inhomogeneities, solutions describing the coupled evolution of the dilaton field and of the fluid sources are scrutinized in both the string and Einstein frames. In semi-realistic scenarios, where the curvature divergences are regularized by means of a non-local dilaton potential, the rotational inhomogeneities are amplified during the pre-big bang phase but they decay later on. Similar analyses can also be performed when a contraction occurs directly in the str...

    Wafer pre-aligning system is an important component in IC manufacturing industry. A wafer prealigning platform with a CCD sensor is presented in this paper. The centering and notch detecting approaches are extended based on this platform. Least square circle fitting approach is adopted to calculate the center and radius of the wafer, and a formula for calculating the fitting error is derived. An approach called edge variation rate is also proposed to detect the range of wafer notch, and the fiducial is calculated by curve fitting approach. These approaches can improve the accuracy effectively as indicated by experiments.

    1997-10-01

    The pre-big-bang cosmology inspired by superstring theories has been suggested as an alternative to slow-roll inflation. We analyze, in both the Jordan and Einstein frames, the effect of spatial curvature on this scenario and show that too much curvature --- of either sign --- reduces the duration of the inflationary era to such an extent that the flatness and horizon problems are not solved. Hence, a fine-tuning of initial conditions is required to obtain enough inflation to solve the cosmological problems.

  10. Pre-energy reasoning in preschool children

    Directory of Open Access Journals (Sweden)

    DIMITRIS KOLIOPOULOS

    2009-01-01

    Full Text Available The research presented in this paper explores the degree to which preschool children have the ability to use mental representations which constitute precursor energy models. Twenty-five children (10 boys and 15 girls participated in the study. They were presented with two different phenomenological situations considered as important for the establishment of pre-energy reasoning: the movement of a toy car with the use of batteries and the movement of an identical car with the use of a spring. The children were involved in personal, semi-structured interviews, which aimed at eliciting their explanations about the movement of the two cars. The analysis of children’s explanations reveals that they tend to explain the movement of cars in both phenomenological situations in naturalistic terms. These naturalistic explanations were mainly agentive, that is they regard the batteries and the spring correspondingly as external agents causing the cars’ movement. The major percentage of agentive naturalistic explanations was given in terms of the function of the objects under discussion, while a number of them were formulated in terms of distribution. These findings designate a developing understanding of physical causality and a pre-energy character in children’s reasoning, since they are capable of accounting for the two phenomenological situations in terms of object chains. Therefore, an attempt to introduce the aspect of energy transfer in preschool education could be considered.

  11. Neuroimaging in pre-motor Parkinson's disease

    Directory of Open Access Journals (Sweden)

    Thomas R. Barber

    2017-01-01

    Full Text Available The process of neurodegeneration in Parkinson's disease begins long before the onset of clinical motor symptoms, resulting in substantial cell loss by the time a diagnosis can be made. The period between the onset of neurodegeneration and the development of motoric disease would be the ideal time to intervene with disease modifying therapies. This pre-motor phase can last many years, but the lack of a specific clinical phenotype means that objective biomarkers are needed to reliably detect prodromal disease. In recent years, recognition that patients with REM sleep behaviour disorder (RBD are at particularly high risk of future parkinsonism has enabled the development of large prodromal cohorts in which to investigate novel biomarkers, and neuroimaging has generated some of the most promising results to date. Here we review investigations undertaken in RBD and other pre-clinical cohorts, including modalities that are well established in clinical Parkinson's as well as novel imaging methods. Techniques such as high resolution MRI of the substantia nigra and functional imaging of Parkinsonian brain networks have great potential to facilitate early diagnosis. Further longitudinal studies will establish their true value in quantifying prodromal neurodegeneration and predicting future Parkinson's.

    Twitter text messages are very noisy. Moreover, tweet data are unstructured and complicated enough. The focus of this work is to investigate pre-processing technique for Twitter messages in Bahasa Indonesia. The main goal of this experiment is to clean the tweet data for further analysis. Thus, the objectives of this pre-processing task is simply removing all meaningless character and left valuable words. In this research, we divide our proposed pre-processing experiments into two parts. The first part is common pre-processing task. The second part is a specific pre-processing task for tweet data. From the experimental result we can conclude that by employing a specific pre-processing task related to tweet data characteristic we obtained more valuable result. The result obtained is better in terms of less meaningful word occurrence which is not significant in number comparing to the result obtained by just running common pre-processing tasks.

    Congenital hearing loss still remain an important medical and social problem for the delayed language development. Object of this study is to provide an updated and close estimate of the economic burden involved in pre-lingual hearing loss. Data were provided by the Ministry of Health data bank, the Ministry of Education national data bank, the National Institute of Social Insurance national data bank and the Italian Central Statistics Institute. The information was collected by means of a specially provided Societal Cost Questionnaire (SCQ). Direct medical costs, direct non-medical costs and indirect welfare costs involved in deafness were included in the cost estimate. Was enrolled in the study a sample of subjects with pre-lingual deafness, with a mean bilateral neuro-sensorial hearing impairment equal to 60 dB or more for 500, 1,000 and 2,000 Hz frequency tones in the better ear detected in neonatal age, had prevented speech from developing. The statistical assessment was performed according to an actuarial approach, considering the estimated life expectancy at birth, based on updated population data from census 2001. Based on life expectancy, the lifetime mean cost assessed for a subject affected by profound pre-lingual deafness turned out to be equal to Euro 737,994.76 for a male and Euro 755,404.02 for a female. Unlike other disabling affections, deafness weighs significantly more on the social system than on the health system. As a matter of fact, the direct medical costs, such as audiological diagnosis, hearing aids, etc., only account for 3.8% of the societal cost, whereas education, rehabilitation and welfare costs reach 96.2% of the total. Finally, our results suggest that societal costs can only be reduced by zeroing in on promotion and broadening of effective prevention strategies. The appropriate public health measures (such as the universal newborn hearing screening) set up and implemented in several European and non-European countries proved

  2. Pre-operative antiseptic skin preparation.

    Science.gov (United States)

    Murkin, Claire Elizabeth

    Theatre nurses use antiseptic skin preparation products every day, but little thought seems to be given as to why a surgeon has a particular preference for one antiseptic skin preparation over another - whether it is for its efficacy, safety or application properties. Woodhead et al (2004) states that nurses still work in a ritualistic environment. Rituals are 'any action performed according to custom, without understanding the reasons why it is being practised'. Nursing practice should be evidence-based; nurses should understand the rationale behind the choice of a particular antiseptic, and be knowledgable about the clinical effectiveness of antiseptic's use pre-operatively, to achieve optimum results. This article focuses on the main types of antiseptic skin preparation while highlighting each product's activity and the relevant considerations for choosing the appropriate product for each patient. Theatre staff need to emphasize the importance of skin preparation and the correct application techniques, while educating the scrub team and surgeons with respect to skin preparation.

    We present first results of our on-going BIMA Key Project: imaging the CO(1-0) emission from a sample of 10 luminous IR galaxies (LIRGs) that are at various merging stages, with special emphasis on systems apparently in the early/intermediate stages of merging. We present here CO images with $\\sim 5''$ resolution. An important result is the recognition of a plausible pre-starburst phase in some early LIRG mergers (e.g., Arp 302 and NGC 6670). Our initial analysis suggests that a merger-induced starburst phase may not begin before the nuclear separation between the merging galaxies reaches roughly 10 kpc. The surface gas density seems to increase from a few times $10^2 \\Msun pc^{-2} to >10^3 \\Msun pc^{-2}$ while the prominent CO extent systematically decreases as merging progresses.

  5. Perinatal mortality at pre-Columbian Teotihuacan.

    Storey, R

    1986-04-01

    The skeletal population of 166 individuals from a low-status apartment compound of the pre-Columbian city of Teotihuacan contained 52 perinatal individuals. The most perilous time of the lifespan was around birth, as revealed by life table analysis. Femur length was not increasing during the last month of gestation, and individuals were probably shorter somatically at birth than modern standards or historic-period Arikara skeletal controls. The possibility of intrauterine growth retardation is investigated through paleo-pathological indicators of prenatal growth arrest. The evidence of prenatal stress and the high rate of mortality at birth seem to indicate that this New World preindustrial urban population faced similar health and nutritional stresses as Old World preindustrial cities.

    2014-01-01

    Several papers provide evidences that the most probable sites of flare onset are the regions of high horizontal magnetic field gradients in solar active regions. Besides the localization of flare producing areas the present work intends to reveal the characteristic temporal variations in these regions prior to flares. This study uses sunspot data instead of magnetograms, it follows the behaviour of a suitable defined proxy measure representing the horizontal magnetic field gradient. The source of the data is the SDD (SOHO/MDI-Debrecen Data) sunspot catalogue. The most promising pre-flare signatures are the following properties of the gradient variation: i) steep increase, ii) high maximum, iii) significant fluctuation and iv) a gradual decrease between the maximum and the flare onset which can be related to the "pull mode" of the current layer. These properties may yield a tool for the assessment of flare probability and intensity within the next 8-10 hours.

    1995-01-01

    After a brief outline of past developments in the training of ambulance personnel, this paper traces the adoption in the UK of Pre-Hospital Trauma Life Support (PHTLS) courses from the US. The 1991 World Student Games in Sheffield, UK led to liaison between training staff from South Yorkshire Metropolitan Ambulance and Paramedic Service (SYMAPS) and from Western New York Medical Training Institute. As a result, the trauma care policy of SYMAPS was altered from aiming to stabilise the patient at the scene of the accident to emphasising rapid and thorough assessment, packaging and transport. This is a resume of the scope of the PHTLS provider course. The course concentrates on the principles of PHTLS for the multisystems trauma victim.

    Barrett, Helen L; Dekker Nitert, Marloes; McIntyre, H David; Callaway, Leonie K

    2014-11-01

    Pre-eclampsia continues to be a challenge--to understand the underlying pathogenesis and to prevent or treat in the clinical setting. One area of potential therapies opening up is treatment of maternal lipids and clinical trials are underway using statins in early pre-eclampsia. At present, most potential therapies to treat lipids cannot be recommended for general use in pregnancy and if we were to target maternal lipids to reduce rates of pre-eclampsia, very large numbers of women may need to be treated. Prior to reaching that point, we first need to understand whether maternal lipids are pathogenic in the processes underlying pre-eclampsia. The aim of this review is to examine the role of lipids in the pathogenesis and outcomes of pre-eclampsia, how abnormal lipid genes may be implicated and consider whether treatment of hyperlipidemia has a more general place in the prevention or treatment of pre-eclampsia.

    In Iwamoto-Harada model the whole phase space is full of fermions. When the momentum distributions of the exciton states are taken into account, the pre-formation probability of light composite particles could be improved,and the exciton state-dependent pre-formation probability has been proposed. The calculated results indicate that the consideration of the momentum distribution enhances the pre-formation probability of [1,m] configuration, and suppresses that of [l > 1, m] configurations seriously.

    2004-01-01

    A semantics-based pre-fetching model is presented. This model predicts future requests based on latent intention that the user's current access path implies in semantics, rather than on temporal relationships, which oversomes the limitation of previous pre-fetching approaches. The hidden Markov model (HMM) was employed for mining actual intention from access patterns. Experimental results show that the proposed pre-fetching model has better general performance.

    2016-06-01

    In this paper, we show that the Jacobiator J of a pre-Courant algebroid is closed naturally. The corresponding equivalence class [J♭ ] is defined as the Pontryagin class, which is the obstruction of a pre-Courant algebroid to be deformed into a Courant algebroid. We construct a Leibniz 2-algebra and a Lie 2-algebra associated to a pre-Courant algebroid and prove that these algebraic structures are isomorphic under deformations. Finally, we introduce the twisted action of a Lie algebra on a manifold to give more examples of pre-Courant algebroids, which include the Cartan geometry.

    Full Text Available Globalisation has helped the number of people to be cognizant of the importance of foreign language teaching and learning. As  it is almost impossible to separate culture from language and the familiarization of  diverse cultures from language do not help students for the real life because people from diverse cultural backgrounds use language differently, Kramsch (1993:258 holds that the aim of language learning is “cultivating international understanding, responsibility, and effective participation in a global age”. The purpose of  this  article is to explore the intercultural sensitivity among teacher trainees. For this purpose two scales were administered to  the pre- service teachers to see to what extent they have intercultural sensitivity and how they see culture teaching in the curriculum. The results yield that Turkish teacher  trainees  integrate language teaching objectives  with culture teaching and they prioritize the attitudinal knowledge, showing tolerance and sympathy for the others.  

  3. Pre-Inca Astronomy in Peru

    Science.gov (United States)

    McKim Malville, J.

    Huacas (shrines) and ushnus (ceremonial platforms) are ever-present elements of millennia-old Andean cosmology extending backward to 3100 BCE. Major themes of Pan-Andean cosmology include sacred mountains, the power of water, the solstice sun, as well as shamanic-like movement across the three worlds of the cosmos. Common features of many pre-Inca sites are monumental platforms and sunken circular plazas, and stairways with axes established by bi-lateral symmetries oriented along solstice lines. This style of ritual architecture first appeared in Chupacigarro/Caral, other sites in the Norte Chico area, and Sechin Bajo in the Casma Valley. Ceremonial plazas provided opportunities for public viewing of ritual ceremonies on the tops of platforms, which may have been understood as sacred mountains. Mounds and temples of the Casma Valley, such as Sechin Alto, Sechin Bajo, and Chankillo, developed an explicit astronomy associated with June and December solstices. The ritualistic use of water, which is typically associated with visual astronomy at Inca sites, appeared at Chavin de Huantar and later in Tiwanaku.

  4. The pre-history of urban scaling.

    2014-01-01

    Cities are increasingly the fundamental socio-economic units of human societies worldwide, but we still lack a unified characterization of urbanization that captures the social processes realized by cities across time and space. This is especially important for understanding the role of cities in the history of human civilization and for determining whether studies of ancient cities are relevant for contemporary science and policy. As a step in this direction, we develop a theory of settlement scaling in archaeology, deriving the relationship between population and settled area from a consideration of the interplay between social and infrastructural networks. We then test these models on settlement data from the Pre-Hispanic Basin of Mexico to show that this ancient settlement system displays spatial scaling properties analogous to those observed in modern cities. Our data derive from over 1,500 settlements occupied over two millennia and spanning four major cultural periods characterized by different levels of agricultural productivity, political centralization and market development. We show that, in agreement with theory, total settlement area increases with population size, on average, according to a scale invariant relation with an exponent in the range [Formula: see text]. As a consequence, we are able to infer aggregate socio-economic properties of ancient societies from archaeological measures of settlement organization. Our findings, from an urban settlement system that evolved independently from its old-world counterparts, suggest that principles of settlement organization are very general and may apply to the entire range of human history.

  5. Pre-Inflationary Relics in the CMB?

    2015-01-01

    String Theory and Supergravity allow, in principle, to follow the transition of the inflaton from pre-inflationary fast roll to slow roll. This introduces an infrared depression in the primordial power spectrum that might have left an imprint in the CMB anisotropy, if it occurred at accessible wavelengths. We model the effect extending $\\Lambda$CDM with a scale $\\Delta$ related to the infrared depression and explore the constraints allowed by {\\sc Planck} data, employing also more conservative, wider Galactic masks in the low resolution CMB likelihood. In an extended mask with $f_{sky}=39\\%$, we thus find $\\Delta = (0.351 \\pm 0.114) \\times 10^{-3} \\, \\mbox{Mpc}^{-1}$, at $99.4\\%$ confidence level, to be compared with a nearby value at $88.5\\%$ with the standard $f_{sky}=94\\%$ mask. With about 64 $e$--folds of inflation, these values for $\\Delta$ would translate into primordial energy scales ${\\cal O}(10^{14})$ GeV.

    Full Text Available Several binaural audio signal enhancement algorithms were evaluated with respect to their potential to improve speech intelligibility in noise for users of bilateral cochlear implants (CIs. 50% speech reception thresholds (SRT50 were assessed using an adaptive procedure in three distinct, realistic noise scenarios. All scenarios were highly nonstationary, complex, and included a significant amount of reverberation. Other aspects, such as the perfectly frontal target position, were idealized laboratory settings, allowing the algorithms to perform better than in corresponding real-world conditions. Eight bilaterally implanted CI users, wearing devices from three manufacturers, participated in the study. In all noise conditions, a substantial improvement in SRT50 compared to the unprocessed signal was observed for most of the algorithms tested, with the largest improvements generally provided by binaural minimum variance distortionless response (MVDR beamforming algorithms. The largest overall improvement in speech intelligibility was achieved by an adaptive binaural MVDR in a spatially separated, single competing talker noise scenario. A no-pre-processing condition and adaptive differential microphones without a binaural link served as the two baseline conditions. SRT50 improvements provided by the binaural MVDR beamformers surpassed the performance of the adaptive differential microphones in most cases. Speech intelligibility improvements predicted by instrumental measures were shown to account for some but not all aspects of the perceptually obtained SRT50 improvements measured in bilaterally implanted CI users.

  7. Pre-, Pro-, Synbiotics and Human Health

    2010-01-01

    Full Text Available Western lifestyle is associated with a sustained low grade increase in inflammation leading to an impaired innate immunity and reduced resistance to disease, changes which might explain the epidemic of chronic diseases spreading around the globe. The immune system cannot function properly without access to bacteria and plants, which when raw, are rich not only in bacteria but also in plant fibres, antioxidants, healthy fats and numerous other nutrients. Modern food technology with plant breeding, separation, condensation of food ingredients, heating, freezing, drying, irradiation, microwaving, an effective tool for destroying foods and hereby counteracting optimal immune function, is suspected to be a leading cause of so-called Western diseases. The supply of pre-, pro-, and synbiotics has sometimes proved to be effective tool to counteract, especially acute diseases, but has often failed, especially in chronic diseases. Thousands of factors contribute to unhealthy living. Numerous alterations in lifestyle and food habits are needed, if to prevent and cure 'treatment-resistant' chronic diseases. Among these are avoiding such processed foods that are known to be rich in pro-inflammatory molecules, and also eating substantial amounts of foods with documented anti-inflammatory effects such as turmeric/curcumin, molecules which might be included in future synbiotic compositions.

  8. Microbial communities in pre-columbian coprolites.

    Tasha M Santiago-Rodriguez

    Full Text Available The study of coprolites from earlier cultures represents a great opportunity to study an "unaltered" composition of the intestinal microbiota. To test this, pre-Columbian coprolites from two cultures, the Huecoid and Saladoid, were evaluated for the presence of DNA, proteins and lipids by cytochemical staining, human and/or dog-specific Bacteroides spp. by PCR, as well as bacteria, fungi and archaea using Terminal Restriction Fragment analyses. DNA, proteins and lipids, and human-specific Bacteroides DNA were detected in all coprolites. Multidimensional scaling analyses resulted in spatial arrangements of microbial profiles by culture, further supported by cluster analysis and ANOSIM. Differences between the microbial communities were positively correlated with culture, and SIMPER analysis indicated 68.8% dissimilarity between the Huecoid and Saladoid. Proteobacteria, Bacteroidetes and methanogens were found in all coprolite samples. Propionebacteria, Shewanella and lactic acid bacteria dominated in the Huecoid samples, while Acidobacteria, and peptococci were dominant in Saladoid samples. Yeasts, including Candida albicans and Crypotococcus spp. were found in all samples. Basidiomycetes were the most notable fungi in Huecoid samples while Ascomycetes predominated in Saladoid samples, suggesting differences in dietary habits. Our study provides an approach for the study of the microbial communities of coprolite samples from various cultures.

  9. Capturing a flavivirus pre-fusion intermediate.

    Directory of Open Access Journals (Sweden)

    2009-11-01

    Full Text Available During cell entry of flaviviruses, low endosomal pH triggers the rearrangement of the viral surface glycoproteins to a fusion-active state that allows the release of the infectious RNA into the cytoplasm. In this work, West Nile virus was complexed with Fab fragments of the neutralizing mAb E16 and was subsequently exposed to low pH, trapping the virions in a pre-fusion intermediate state. The structure of the complex was studied by cryo-electron microscopy and provides the first structural glimpse of a flavivirus fusion intermediate near physiological conditions. A radial expansion of the outer protein layer of the virion was observed compared to the structure at pH 8. The resulting approximately 60 A-wide shell of low density between lipid bilayer and outer protein layer is likely traversed by the stem region of the E glycoprotein. By using antibody fragments, we have captured a structural intermediate of a virus that likely occurs during cell entry. The trapping of structural transition states by antibody fragments will be applicable for other processes in the flavivirus life cycle and delineating other cellular events that involve conformational rearrangements.

    ''Brane supersymmetry breaking'' occurs in String Theory when the only available combinations of D-branes and orientifolds are not mutually BPS and yet do not introduce tree-level tachyon instabilities. It is characterized by the emergence of a steep exponential potential, and thus by the absence of maximally symmetric vacua. The corresponding low-energy supergravity admits intriguing spatially-flat cosmological solutions where a scalar field is forced to climb up toward the steep potential after an initial singularity, and additional milder terms can inject an inflationary phase during the ensuing descent. We show that, in the resulting power spectra of scalar perturbations, an infrared suppression is typically followed by a pre-inflationary peak that reflects the end of the climbing phase and can lie well apart from the approximately scale invariant profile. A first look at WMAP9 raw data shows that, while the χ{sup 2} fits for the low-ℓ CMB angular power spectrum are clearly compatible with an almost scale invariant behavior, they display nonetheless an eye-catching preference for this type of setting within a perturbative string regime.

  14. The pre-Caledonian margin of Baltica

    Andersen, Torgeir B.; Jørgen Kjøll, Hans; Jakob, Johannes; Corfu, Fernando; Tegner, Christian

    2017-04-01

    It is well-documented that the pre-Caledonian margin of Baltica constituted a several hundred-km wide and more than 2000 km long passive margin. Its vestiges occur at low- to intermediate structural levels in the mountain belt, and are variably overprinted by the early- to end-Caledonian orogenic deformation and extension. Attempts to reconstruct the Caledonian margin of Baltica must be based on detailed maps integrated with studies of the rock-complexes that originally constituted the passive margin. The proximal parts of pre-Caledonian margin of Baltica are dominated by continental rift basins with coarse to fine-grained sediments deposited in the late Proterozoic through the Ediacaran and into the Lower Palaeozoic. The youngest dated clastic zircons probably record magmatism associated with initial contraction near or in the distal margin. The 'margin nappes' also comprise Baltican basement slivers and coarse to fine-grained sedimentary units as well as deep-marine basin deposits. A major change in the architecture of the passive margin units takes place across a transvers zone, which is sub-parallel to the present-day Gudbrandsdalen of South Norway. The transition is roughly parallel to the major basement lineament of the Sveconorwegian orogenic front in south Norway. The most important change across this transverse lineament is that the NE segment is magma-rich, characterized by abundant basaltic magmatism. The SW segment is magma-poor, and characterised by numerous (>100) solitary meta-peridotites, mostly meta-dunites and meta-harzburgites as well as a number of detrital serpentinites and soapstones. These are interpreted as fragments of exhumed mantle and their erosion products, respectively. The meta-peridotites emplaced structurally, and covered by dominantly deep-basin sediments, but also by coarser sedimentary breccias and conglomerates, as part of the rifted margin development. This mixed unit (mélange) was locally intruded by Late Cambrian to Early

    2015-12-18

    Asymptomatic bacteriuria is one of the most common and important bacterial infections during pregnancy and can result in progressive infections and endanger maternal as well as fetal health. In this study, we assessed the relationship between asymptomatic bacteriuria and pre-eclampsia. In this case-control study, pregnant women who presented to Imam Reza Hospital in Kermanshah in 2013-14 were studied. The minimum sample size was calculated as 125 pregnant women in each group with a total of 250 subjects. There were 125 women with pre-eclampsia and 125 women without pre-eclampsia (control group). Matching was done for age, gestational age, and parity between case and control groups. Matching was verified by a P value of 0.061 for maternal age and gestational age and 0.77 for parity. The statistical analyses were done by applying the chi-squared test and determining odds ratio (OR) for having bacteriuria in univariate logistic regression as well as multivariate regression with adjusting the effect of maternal age, gestational age, and parity. Pyuria and bacteriuria were significantly more common in pre-eclampsia group than in control group. The results showed that a significant association existed between asymptomatic bacteriuria and pre-eclampsia. The rate of asymptomatic bacteriuria was 6.8 times higher in women with pre-eclampsia compared to those without pre-eclampsia. Further studies are required for better clarification of association between asymptomatic bacteriuria and pre-eclampsia.

  7. LIF supports primitive endoderm expansion during pre-implantation development

    DEFF Research Database (Denmark)

    Morgani, Sophie M; Brickman, Joshua M

    2015-01-01

    report that LIF has two distinct roles: it blocks early epiblast (Epi) differentiation, and it supports the expansion of primitive endoderm (PrE)-primed ESCs and PrE in vivo. We find that activation of JAK/STAT signalling downstream of LIF occurs initially throughout the pre-implantation embryo......, but later marks the PrE. Moreover, the addition of LIF to cultured embryos increases the GATA6(+) PrE population, whereas inhibition of JAK/STAT signalling reduces both NANOG(+) epiblast and GATA6(+) PrE. The reduction of the NANOG(+) Epi might be explained by its precocious differentiation to later Epi...... derivatives, whereas the increase in PrE is mediated both by an increase in proliferation and inhibition of PrE apoptosis that is normally triggered in embryos with an excess of GATA6(+) cells. Thus, it appears that the relative size of the PrE is determined by the number of LIF-producing cells in the embryo...

  15. Organ donation and pre-emptive kidney transplantation: ethical issues.

    Science.gov (United States)

    Petrini, C

    2013-01-01

    There is considerable evidence that pre-emptive transplants have several clinical advantages. However, pre-emptive transplants raise a number of ethical issues. Pre-emptive transplants from living donors offer distinctly greater benefits than those from deceased donors and some pre-emptive transplantation programmes actively encourage living organ donations. Moreover, the offer of a pre-emptive transplant to a patient who is not yet on dialysis unquestionably penalises patients already on dialysis who may have been on the waiting list for a long time. Therefore preemptive transplants give rise to conflicts between justice and utility. Several factors should be considered: health conditions, clinical urgency, probability of imminent worsening of a patient's clinical condition, the future chances of finding a matching organ, and others. From the various values at stake, ethical issues are analysed in search of an acceptable synthesis.

  16. Combined Screening for Early Detection of Pre-Eclampsia

    Directory of Open Access Journals (Sweden)

    Hee Jin Park

    2015-08-01

    Full Text Available Although the precise pathophysiology of pre-eclampsia remains unknown, this condition continues to be a major cause of maternal and fetal mortality. Early prediction of pre-eclampsia would allow for timely initiation of preventive therapy. A combination of biophysical and biochemical markers are superior to other tests for early prediction of the development of pre-eclampsia. Apart from the use of parameters in first-trimester aneuploidy screening, cell-free fetal DNA quantification is emerging as a promising marker for prediction of pre-eclampsia. This article reviews the current research of the most important strategies for prediction of pre-eclampsia, including the use of maternal risk factors, mean maternal arterial pressure, ultrasound parameters, and biomarkers.

  17. Web Pre-fetching Model Based on Concept Association Network

    Institute of Scientific and Technical Information of China (English)

    XUHuanqing; WANGYongcheng

    2004-01-01

    With the enormous growth of information on the web, Internet has become one of the most important information sources. However, limited by the network bandwidth, users always suffer from long time waiting. Web pre-fetching is one of the most popular strategies,which are proposed for reducing the perceived access delay and improving the service quality of web server. This paper presents a pre-fetching model based on concept as sociation network, which mines concept association relationships that are implied in user access patterns and employs online learning and oitiine mining algorithm to construct the user-oriented concept association network. Using concept association network, pre-fetching model makes semantics-based pre-fetching decisions in the client side.This model implements the concept-based analysis on user access patterns and improves the prediction accuracy. Experimental results show that the proposed pre-fetching model has better general performance.

  18. Gene expression profiling of placentas affected by pre-eclampsia

    DEFF Research Database (Denmark)

    Hoegh, Anne Mette; Borup, Rehannah; Nielsen, Finn Cilius;

    2010-01-01

    Several studies point to the placenta as the primary cause of pre-eclampsia. Our objective was to identify placental genes that may contribute to the development of pre-eclampsia. RNA was purified from tissue biopsies from eleven pre-eclamptic placentas and eighteen normal controls. Messenger RNA...... expression from pooled samples was analysed by microarrays. Verification of the expression of selected genes was performed using real-time PCR. A surprisingly low number of genes (21 out of 15,000) were identified as differentially expressed. Among these were genes not previously associated with pre-eclampsia...... as bradykinin B1 receptor and a 14-3-3 protein, but also genes that have already been connected with pre-eclampsia, for example, inhibin beta A subunit and leptin. A low number of genes were repeatedly identified as differentially expressed, because they may represent the endpoint of a cascade of events...

    Several studies point to the placenta as the primary cause of pre-eclampsia. Our objective was to identify placental genes that may contribute to the development of pre-eclampsia. RNA was purified from tissue biopsies from eleven pre-eclamptic placentas and eighteen normal controls. Messenger RNA...... expression from pooled samples was analysed by microarrays. Verification of the expression of selected genes was performed using real-time PCR. A surprisingly low number of genes (21 out of 15,000) were identified as differentially expressed. Among these were genes not previously associated with pre-eclampsia...... as bradykinin B1 receptor and a 14-3-3 protein, but also genes that have already been connected with pre-eclampsia, for example, inhibin beta A subunit and leptin. A low number of genes were repeatedly identified as differentially expressed, because they may represent the endpoint of a cascade of events...

    Although the precise pathophysiology of pre-eclampsia remains unknown, this condition continues to be a major cause of maternal and fetal mortality. Early prediction of pre-eclampsia would allow for timely initiation of preventive therapy. A combination of biophysical and biochemical markers are superior to other tests for early prediction of the development of pre-eclampsia. Apart from the use of parameters in first-trimester aneuploidy screening, cell-free fetal DNA quantification is emerging as a promising marker for prediction of pre-eclampsia. This article reviews the current research of the most important strategies for prediction of pre-eclampsia, including the use of maternal risk factors, mean maternal arterial pressure, ultrasound parameters, and biomarkers.

    2011-08-01

    Edge cracking in advanced high strength steels (AHSS) is a significant failure mode in many sheet metal stamping processes. Edge pre-forming into a wave (or scallop) shape is a common technique used in conventional steels to gather material in high edge stretch regions in preparation for the subsequent edge stretch process. The pre-forms designed for mild steels do not always apply to AHSS because the properties of AHSS can differ greatly from those of conventional steels. This work has studied the effects of pre-forming on AHSS edge cracking. Experiments have been conducted to stretch pre-formed steel strips to failure. Strain distributions of pre-forms with various levels of stretch have been measured using digital image correlation (DIC) technology. Finite element analyses have been performed and compared with the experimental results. Different failure criteria have also been evaluated for use in this type of application.

    Full Text Available Background The main causes of maternal mortality in Indonesia are pre-eclampsia, hemorrhage, and infection. Oxidative stress has a primary role in pre-eclampsia and one of its parameters is 8-isoprostane serum level. The objective of this study is to measure 8-isoprostane and to analyze the relationship between 8-isoprostane level and birth weight in pre-eclampsia. Methods A cross-sectional study involving 23 pre-eclampsia and 29 normotensive pregnant women with normal or cesarean delivery at Dr. Kariadi Hospital Semarang from January to May 2011. Collected maternal blood samples were assessed for 8-Isoprostane levels by means of a specific ELISA kit. Neonatal birth weight was measured immediately after delivery by means of calibrated baby scales. Differences in 8-isoprostane levels between pre-eclampsia and normotensive women were assessed using independent t-test for normal distributed data, and the Mann-Whitney test for non-normally distributed data. Results Mean 8-isoprostane level was significantly higher in women with pre-eclampsia than in normotensive women (62.52 ± 12.19 pg/mL vs 28.64 ± 8.81 pg/mL (p<0.05. Low birth weight was twice as frequent in pre-eclampsia than in normotensives. There was no correlation between 8-isoprostane serum level and neonatal birth weight in pre-eclampsia. Conclusion The level of 8-isoprostane was higher in pre-eclampsia than in normotensives. It is recommended to conduct further studies to determine whether 8-isoprostane may be used as a predictive marker of pre-eclampsia.

    This infrared image of Jupiter's moon Ganymede, showing heat radiation from its surface at a wavelength of 27 microns (millionths of a meter), provides the best view yet of pre-dawn temperatures on Ganymede. Temperatures, derived from the brightness of the infrared radiation, can be determined from the colors by reference to the scale at the bottom of the image.The image, taken by NASA's Galileo spacecraft, shows half of Ganymede's disk as seen by the approaching spacecraft. Longitudes covered range from 340 on the right of the image, through longitude zero (the direction facing Jupiter) to longitude 60 near Ganymede's limb on the left. The morning terminator, near longitude 15, curves through the middle of the image, separating areas experiencing the last hours of the long (3.5 Earth day) Ganymede night, on the left, from areas that are warming up in the morning sunshine, on the right. Ganymede's north pole is in the upper right corner of the image, and the south pole is in the lower right. Ganymede rotates from left to right.Nighttime temperatures, shown in blue and purple colors, are in the range 85 - 100 Kelvin (-306 to -279 F). The surface cools steadily during the night, so the warmest nighttime temperatures are on the left side of the disk, and temperatures drop towards the dawn terminator on the right, before warming rapidly once the sun rises (the red, yellow and white areas on the far right). Study of the rate of nighttime cooling and the rate of post-sunrise warming, will provide information about Ganymede's surface properties.The image was taken with Galileo's PPR (Photopolarimeter-Radiometer) instrument on the spacecraft's seventh orbit around Jupiter, from a range of about 190,000 kilometers (118,060 miles). Surface temperatures derived from the strength of infrared radiation, as was done here, are called 'brightness temperatures', and may be slightly in error.The PPR instrument builds up an image by slowly scanning across the target over a period of

    The debate about how, where and by whom young children should be looked after is one which has occupied much social policy and media attention in recent years. Mothers undertake most of the care of young children. Internationally, out-of-home day-care provision ranges widely. These different levels of provision are not simply a response to different levels of demand for day-care, but reflect cultural and economic interests concerning the welfare of children, the need to promote mothers' participation in paid work, and the importance of socialising children into society's values. At a time when a decline in family values is held responsible for a range of social problems, the day-care debate has a special prominence. To quantify the effects of out-of-home day-care for preschool children on educational, health and welfare outcomes for children and their families. Randomised controlled trials of day-care for pre-school children were identified using electronic databases, hand searches of relevant literature, and contact with authors. Studies were included in the review if the intervention involved the provision of non-parental day care for children under 5 years of age, and the evaluation design was that of a randomised or quasi-randomised controlled trial. A total of eight trials were identified after examining 920 abstracts and 19 books. The trials were assessed for methodological quality. Day-care increases children's IQ, and has beneficial effects on behavioural development and school achievement. Long-term follow up demonstrates increased employment, lower teenage pregnancy rates, higher socio-economic status and decreased criminal behaviour. There are positive effects on mothers' education, employment and interaction with children. Effects on fathers have not been examined. Few studies look at a range of outcomes spanning the health, education and welfare domains. Most of the trials combined non-parental day-care with some element of parent training or education

    Full Text Available Pre-exposure prophylaxis (PrEP is an experimental approach to HIV prevention and consists of antiretroviral drugs to be taken before potential HIV exposure in order to reduce the risk of HIV infection and continued during periods of risk. An effective PrEP could provide an additional safety net to sexually active persons at risk, when combined with other prevention strategies. Women represent nearly 60% of adults infected with HIV and PrEP can be a female-controlled prevention method for women who are unable to negotiate condom use. Two antiretroviral nucleoside analog HIV-1 reverse transcriptase inhibitor drugs are currently under trial as PrEP drugs, namely tenofovirdisoproxilfumarate (TDF alone and TDF in combination with emricitabine (FTC, to be taken as daily single dose oral drugs. There are 11 ongoing trials of ARV-based prevention in different at risk populations across the world. The iPrex trial showed that daily use of oral TDF/FTC by MSM resulted in 44% reduction in the incidence of HIV. This led to publication of interim guidance by CDC to use of PrEP by health providers for MSM. Few other trials are Bangkok Tenofovir Study, Partners PrEP Study, FEM-PrEP study, and VOICE (MTN-003 study. Future trials are being formulated for intermittent PrEP (iPrEP where drugs are taken before and after sex, "stand-in dose" iPrEP, vaginal or rectal PrEP, etc. There are various issues/concerns with PrEP such as ADRs and resistance to TDF/FTC, adherence to drugs, acceptability, sexual disinhibition, use of PrEP as first line of defense for HIV without other prevention strategies, and cost. The PrEP has a potential to address unmet need in public health if delivered as a part of comprehensive toolkit of prevention services, including risk-reduction, correct and consistent use of condoms, and diagnosis and treatment of sexually transmitted infections.

    Various factors affect medical students' performance during clinical phase. Identifying these factors would help in mentoring weak students and help in selection process for residency programmes. Our study objective is to evaluate the impact of pre-admission criteria, and pre-clinical grade point average (GPA) on undergraduate medical students' performance during clinical phase. This study has a cross-sectional design that includes fifth- and sixth-year female medical students (71). Data of clinical and pre-clinical GPA in medical school and pre-admission to medical school tests scores were collected. A significant correlation between clinical GPA with the pre-clinical GPA was observed (p performed, and the only significant predictor of students clinical performance was the pre-clinical GPA (p GPA for both cohorts was observed (p > 0.05). Pre-clinical GPA is strongly correlated with and can predict medical students' performance during clinical years. Our study highlighted the importance of evaluating the academic performances of students in pre-clinical years before they move into clinical years in order to identify weak students to mentor them and monitor their progress.

  7. Who are the young adult Danish pre-drinkers, and why do they pre-drink before a night out?

    2014-06-01

    To reveal young Danes' main motive for pre-drinking and whether their motives and socio economic status can explain how much they pre-drink on an event-specific night out. A binary logistic and negative binomial regression models were used on a survey of 670 Danes (aged 18-35 years) conducted on-site in 24 bars, clubs and pubs in four cities and towns in Denmark. Young males drink on average 12.3 and females 9.3 standard units (defined as 8 g of pure ethanol) of alcohol before a night out. Pre-drinking to be social is the most prevalent motive. Although lower income levels cannot explain whether a young person will pre-drink on an event-specific night out, young people's income level and their motives explain the quantities they consume. Lower-earning males who pre-drank to save money consumed larger quantities of alcohol at home, but lower-earning females pre-drank larger quantities because they wanted to be out of control. Not only young people's motives for pre-drinking but also the price of off- and on-premises alcohol should be considered for outlining prevention strategies seeking to reduce the alcohol quantities that young people pre-drink before a night out. © 2014 the Nordic Societies of Public Health.

  9. Pre-analytical workstations: a tool for reducing laboratory errors.

    2009-06-01

    Laboratory testing, a highly complex process commonly called the total testing process (TTP), is usually subdivided into three traditional (pre-, intra-, and post-) analytical phases. The majority of errors in TTP originate in the pre-analytical phase, being due to individual or system design defects. In order to reduce errors in TTP, the pre-analytical phase should therefore be prioritized. In addition to developing procedures, providing training, improving interdepartmental cooperation, information technology and robotics may be a tool to reduce errors in specimen collection and pre-analytical sample handling. It has been estimated that >2000 clinical laboratories worldwide use total or subtotal automation supporting pre-analytic activities, with a high rate of increase compared to 2007; the need to reduce errors seems to be the catalyst for increasing the use of robotics. Automated systems to prevent medical personnel from drawing blood from the wrong patient were introduced commercially in the early 1990s. Correct patient identification and test tube labelling before phlebotomy are of extreme importance for patient safety in TTP, but currently few laboratories are interested in such products. At San Bassiano hospital, the implementation of advanced information technology and robotics in the pre-analytical phase (specimen collection and pre-analytical sample handling) have improved accuracy, and clinical efficiency of the laboratory process and created a TTP that minimizes errors.

    2015-10-01

    Dietary deficiencies of folate and other B vitamin cofactors involved in one-carbon metabolism, together with genetic polymorphisms in key folate-methionine metabolic pathway enzymes, are associated with increases in circulating plasma homocysteine, reduction in DNA methylation patterns, and genome instability events. All of these biomarkers have also been associated with pre-eclampsia. The aim of this review was to explore the literature and identify potential knowledge gaps in relation to the role of folate at the genomic level in either the etiology or the prevention of pre-eclampsia. A systematic search strategy was designed to identify citations in electronic databases for the following terms: folic acid supplementation AND pre-eclampsia, folic acid supplementation AND genome stability, folate AND genome stability AND pre-eclampsia, folic acid supplementation AND DNA methylation, and folate AND DNA methylation AND pre-eclampsia. Forty-three articles were selected according to predefined selection criteria. The studies included in the present review were not homogeneous, which made pooled analysis of the data very difficult. The present review highlights associations between folate deficiency and certain biomarkers observed in various tissues of women at risk of pre-eclampsia. Further investigation is required to understand the role of folate in either the etiology or the prevention of pre-eclampsia.

  11. Early Grade Teacher Effectiveness and Pre-K Effect Persistence

    2015-11-01

    Full Text Available In recent years, states have significantly expanded access to prekindergarten (pre-K, and federal policy makers have proposed funding near-universal access across the country. However, researchers know relatively little about the role of subsequent experiences in prolonging or truncating the persistence of benefits for participants. This study examines the interaction between pre-K participation and one of our most important educational interventions—teaching quality. We pair student-level data from a statewide pre-K experiment with records of teacher observation scores from Tennessee’s new formal evaluation program to assess whether a student’s access to high-quality early grade teachers moderates the persistence of pre-K effects. Our analyses indicate a small positive interaction between teaching quality and state pre-K exposure on some but not all early elementary cognitive measures, such that better teaching quality in years subsequent to pre-K is associated with more persistent positive pre-K effects.

  12. Monitoring Pre-Stressed Composites Using Optical Fibre Sensors

    2016-05-01

    Full Text Available Residual stresses in fibre reinforced composites can give rise to a number of undesired effects such as loss of dimensional stability and premature fracture. Hence, there is significant merit in developing processing techniques to mitigate the development of residual stresses. However, tracking and quantifying the development of these fabrication-induced stresses in real-time using conventional non-destructive techniques is not straightforward. This article reports on the design and evaluation of a technique for manufacturing pre-stressed composite panels from unidirectional E-glass/epoxy prepregs. Here, the magnitude of the applied pre-stress was monitored using an integrated load-cell. The pre-stressing rig was based on a flat-bed design which enabled autoclave-based processing. A method was developed to end-tab the laminated prepregs prior to pre-stressing. The development of process-induced residual strain was monitored in-situ using embedded optical fibre sensors. Surface-mounted electrical resistance strain gauges were used to measure the strain when the composite was unloaded from the pre-stressing rig at room temperature. Four pre-stress levels were applied prior to processing the laminated preforms in an autoclave. The results showed that the application of a pre-stress of 108 MPa to a unidirectional [0]16 E-glass/913 epoxy preform, reduced the residual strain in the composite from −600 µε (conventional processing without pre-stress to approximately zero. A good correlation was observed between the data obtained from the surface-mounted electrical resistance strain gauge and the embedded optical fibre sensors. In addition to “neutralising” the residual stresses, superior axial orientation of the reinforcement can be obtained from pre-stressed composites. A subsequent publication will highlight the consequences of pres-stressing on fibre alignment, the tensile, flexural, compressive and fatigue performance of unidirectional E

    Pre-eclampsia and eclampsia are parts of the broader spectrum of hypertensive disorders complicating pregnancy. This study aims to examine the association between serum inhibin and leptin levels and pre-eclampsia. This study included 98 consecutive cases of pregnant women with pre-eclampsia, together with their 98 pregnant controls, matched for age, gestational week and time period of delivery. Maternal venous blood samples were obtained within 24h before delivery. In addition to serum inhibin and leptin, birth order, multiple pregnancy, maternal age, maternal overweight/obesity, maternal education, maternal smoking and family history of diabetes/hypertension, were examined as risk factors. Multivariate logistic regression analysis was performed. At the univariate analysis, serum inhibin and leptin levels were significantly higher in cases vs. Pre-eclampsia occurred more frequently in primiparous women, whereas overweight and obesity were also associated with pre-eclampsia. At the multivariate analysis, higher serum inhibin levels were associated with pre-eclampsia (multivariate OR=1.09, 95%CI: 1.03-1.17, p=0.004, increase per 0.1ng/mL). On the other hand, leptin was not independently associated with the occurrence of pre-eclampsia (multivariate OR=1.02, 95%CI: 0.95-1.09, p=0.631, increase per 10ng/mL). Elevated serum inhibin levels seem to be associated with pre-eclampsia, reflecting placental dysfunction. Increased serum leptin levels may merely reflect an elevated maternal body mass index, which is a well-known risk factor for pre-eclampsia. Copyright © 2016 Elsevier B.V. All rights reserved.

    Routine ordering of pre-operative investigations yields a low true positive rate and is not cost effective. In this study, case notes of 251 adults who underwent elective surgery were reviewed. Pre-operative investigations were classified as 'indicated' or 'not indicated', based on the national guidelines. Only 56% of all tests done were indicated. The overall rates of expected and unexpected abnormal values from pre-operative blood investigations were 51.1% and 34.4% respectively. This study found that selective testing based on guidelines was beneficial. However, the results also suggest that the local guidelines need to be reviewed.

    The deep inferior epigastric perforator (DIEP) flap can be used to cover large defects of the proximal lower extremity, abdominal wall, perineum, vulva, and buttock. Pre-expanding DIEP flaps cause a possible delay phenomenon improving vascularity, decrease donor site morbidity, and increase the area that can be covered. Pre-expansion requires staged procedures, has risk of extrusion and infection, causes temporary contour deformity during the expansion process, and requires a longer course. Pre-expanded DIEP flaps can be a useful flap with proper patient selection and planning. Copyright © 2016 Elsevier Inc. All rights reserved.

    In recent years, it has been shown that groundwater with a Pre-Holocene component is more common in the Icelandic bedrock than previously thought. Some of the Pre-Holocene water samples are more depleted in delta H-2 and delta O-18 than any mean annual precipitation in Iceland today due to the cold......-Holocene component in the groundwater. The deuterium excess value may also help to identify water from a different climate regime, if no oxygen shift has occurred. The relative abundance of a Pre-Holocene water component of the Icelandic groundwater has led to the understanding that combined interpretation of water...

    Full Text Available This paper proposes a hybrid algorithm of pre training deep networks, using both marked and unmarked data. The algorithm combines and extends the ideas of Self-Taught learning and pre training of neural networks approaches on the one hand, as well as supervised learning and transfer learning on the other. Thus, the algorithm tries to integrate in itself the advantages of each approach. The article gives some examples of applying of the algorithm, as well as its comparison with the classical approach to pre training of neural networks. These examples show the effectiveness of the proposed algorithm.

  20. Pre-migration Trauma Exposure and Psychological Distress for Asian American Immigrants: Linking the Pre- and Post-migration Contexts.

    Li, Miao; Anderson, James G

    2016-08-01

    Drawing on the life course perspective and the assumptive world theory, this paper examines whether pre-migration trauma exposure is associated with psychological distress through post-migration perceived discrimination for Asian American immigrants. The study is based on cross-sectional data from the National Latino and Asian American Study (N = 1639). Structural equation model is used to estimate the relationship between pre-migration trauma, post-migration perceived discrimination, and psychological distress. Additional models are estimated to explore possible variations across ethnic groups as well as across different types of pre-migration trauma experience. Pre-migration trauma exposure is associated with higher levels of psychological distress, both directly and indirectly through higher level of perceived discrimination, even after controlling for demographic/acculturative factors and post-migration trauma exposure. This pattern holds for the following sub-types of pre-migration trauma: political trauma, crime victimization, physical violence, accidental trauma, and relational trauma. Multi-group analyses show that this pattern holds for all Asian immigrant subgroups except the Vietnamese. Studies of immigrant mental health primarily focus on post-migration stressors. Few studies have considered the link between pre- and post-migration contexts in assessing mental health outcomes. The study illustrates the usefulness of bridging the pre- and post-migration context in identifying the mental health risks along the immigrant life course.

    Optimal nutrition is one of the most important aspects in the care of pre-term infants, especially for the gestationally youngest ones. These infants should receive a supply of nutrients that can sustain growth similar to that of a third trimester normal foetus. Traditional pre-term formulas do not ensure an optimal protein supply except when fed at high volumes, with an excess of fat and carbohydrates. Formulas with a protein content of 2-2.5 g 100ml(-1) and a protein/energy (P:E) ratio of less than 3g 100 kcal(-1) are not the best choice for the very low birth weight (VLBW) infants. We have tested a new formulation designed for the nutrition of the VLBW infants that is characterised by a protein content of 2.9 g 100ml(-1) and a P:E ratio of 3.5 g 100 kcal(-1). The milk formula was well tolerated and associated with better weight gain compared with fortified breast milk (18.1 vs. 15.2 g kg(-1)day(-1); p=0.0015). These results were obtained with a noticeably lower fluid supply (157 vs. 177 ml kg day(-1); pday(-1); p<0.0001). Infant length and head circumference did not differ significantly between groups. Currently, the use of a formula with a P:E ratio of 3.5 g 100 kcal(-1) appears to be safe and to represent the best choice available for the gestationally youngest infants.

    One of largest points of attrition for underrepresented minorities in STEM fields is the transition from high school to college. A report from Building Engineering and Science Talent (BEST) demonstrates that underrepresented minorities begin college interested in STEM fields at rates equal to (if nor slightly above) their representation in both college and the population (25%). However, by the time they graduate, underrepresented minorities make up only 15% of STEM majors and only 9% of the STEM advanced degrees. Most of the attrition occurs during the first year of college, when large classes, a lack of mentors and challenging courses lead many students (from all backgrounds) to consider other majors.In 2012 I started the Boston University Pre-Majors Program (or BU Pre-MaP), which is modeled after the University of Washington Pre-Majors in Astronomy Program (UW Pre-MAP), a program for recruiting, mentoring and training underrepresented, first-year introductory astronomy students (and of which I was an architect). As a significant part of the Pre-MAP (or Pre-MaP) model, first-year students are engaged in a research project with a faculty or grad-student mentor and learn many of the skills needed to be successful in science.The BU Pre-MaP uses weekly seminars to introduce students to BU and the college environment, discuss ways to be successful in and out of the classroom, highlights the importance of peer mentoring and cohort building and serves as a mechanism to introduce first-year students to research skills. In teams of two, the Pre-MaP students select (with assistance) a research mentor and work with him/her on a original research project.In addition, Pre-MaP students attend several field trips including (but not limited to) viewing original science documents at the Boston Public Library (including a first edition Copernicus) and an observing run at Lowell Observatory in Arizona.

    In eukaryotes, most protein-coding genes contain introns which are removed by precursor messenger RNA (pre-mRNA) splicing. Alternative splicing is a process by which multiple messenger RNAs (mRNAs) are generated from a single pre-mRNA, resulting in functionally distinct proteins. Recent genome-wide analyses of alternative splicing indicated that in higher eukaryotes alternative splicing is an important mechanism that generates proteomic complexity and regulates gene expression. Mis-regulation of splicing causes a wide range of human diseases. This review describes the current understanding of pre-mRNA splicing and the mechanisms that regulate mammalian pre-mRNA splicing. It also discusses emerging directions in the field of alternative splicing.

    Pre-stressed rope reinforced anti-sliding pile is a composite anti-sliding structure. It is made up of pre-stressed rope and general anti-sliding pile. It can bring traditional anti-sliding pile's retaining performance into full play, and to treat with landslide fast and economically. The difference between them is that the pre-stressed rope will transfix the whole anti-sliding pile through a prearranged pipe in this structure. The working mechanics, the design method and economic benefit are studied. The results show that the pre-stressed rope reinforced anti-sliding pile can treat with the small and middle landslides or high slopes well and possess the notable advantage of technology and economic.

    The goal of this work is to determine the best conditions for pre-ionization of the nitrogen filled capillary plasma column applying an external exponentially damped or high-frequency alternating current. As we supposed, optimal pre-ionization conditions are achieved when the plasma is quiescent, motionless and isothermal, near the local thermodynamical equilibrium. At the time of optimal conditions for the pre-ionization plasma column, the main pulse is applied. This approach enables us to estimate the influence of such prepared plasma on the value of emitted energy during the main current pulse. For modeling of plasma during the pre-pulse and main pulse, the magneto-hydro-dynamics (MHD) NPINCH code [1] and the radiative-MHD Z* code [2] were used. The computer results are used for further improvement of x-ray-ultraviolet-capillary sources designed in IPP ASCR and CTU FNSPE laboratories in Prague.

    2015-06-01

    Almost 30 years ago pioneering work by the laboratories of Harald von Boehmer and Susumo Tonegawa provided the first indications that developing thymocytes could assemble a functional TCRβ chain-containing receptor complex, the pre-TCR, before TCRα expression. The discovery and study of the pre-TCR complex revealed paradigms of signaling pathways in control of cell survival and proliferation, and culminated in the recognition of the multifunctional nature of this receptor. As a receptor integrated in a dynamic developmental process, the pre-TCR must be viewed not only in the light of the biological outcomes it promotes, but also in context with those molecular processes that drive its expression in thymocytes. This review article focuses on transcription factors and target genes activated by the pre-TCR to drive its different outcomes.

  2. Immune Evasion Strategies of Pre-Erythrocytic Malaria Parasites

    2014-01-01

    Full Text Available Malaria is a mosquito-borne infectious disease of humans. It begins with a bite from an infected female Anopheles mosquito and leads to the development of the pre-erythrocytic and blood stages. Blood-stage infection is the exclusive cause of clinical symptoms of malaria. In contrast, the pre-erythrocytic stage is clinically asymptomatic and could be an excellent target for preventive therapies. Although the robust host immune responses limit the development of the liver stage, malaria parasites have also evolved strategies to suppress host defenses at the pre-erythrocytic stage. This paper reviews the immune evasion strategies of malaria parasites at the pre-erythrocytic stage, which could provide us with potential targets to design prophylactic strategies against malaria.

  3. Fire-free land use in pre-1492 Amazonian savannas.

    The nature and scale of pre-Columbian land use and the consequences of the 1492 "Columbian Encounter" (CE) on Amazonia are among the more debated topics in New World archaeology and paleoecology. However, pre-Columbian human impact in Amazonian savannas remains poorly understood. Most paleoecological studies have been conducted in neotropical forest contexts. Of studies done in Amazonian savannas, none has the temporal resolution needed to detect changes induced by either climate or humans before and after A.D. 1492, and only a few closely integrate paleoecological and archaeological data. We report a high-resolution 2,150-y paleoecological record from a French Guianan coastal savanna that forces reconsideration of how pre-Columbian savanna peoples practiced raised-field agriculture and how the CE impacted these societies and environments. Our combined pollen, phytolith, and charcoal analyses reveal unexpectedly low levels of biomass burning associated with pre-A.D. 1492 savanna raised-field agriculture and a sharp increase in fires following the arrival of Europeans. We show that pre-Columbian raised-field farmers limited burning to improve agricultural production, contrasting with extensive use of fire in pre-Columbian tropical forest and Central American savanna environments, as well as in present-day savannas. The charcoal record indicates that extensive fires in the seasonally flooded savannas of French Guiana are a post-Columbian phenomenon, postdating the collapse of indigenous populations. The discovery that pre-Columbian farmers practiced fire-free savanna management calls into question the widely held assumption that pre-Columbian Amazonian farmers pervasively used fire to manage and alter ecosystems and offers fresh perspectives on an emerging alternative approach to savanna land use and conservation that can help reduce carbon emissions.

    Full Text Available Abstract Proteinuria is a defining criterion for the diagnosis of pre-eclampsia. The amount of protein lost per day has been thought by some to predict both maternal and fetal outcome. The systematic review of 16 primary papers including over 6700 patients by Thangaratinam and colleagues published this month in BMC Medicine suggests otherwise. This finding may influence our management of pre-eclampsia.

    2016-03-01

    Full Text Available Hypertensive disorders of pregnancy complicate about 5-10% of all pregnancies. According to world health organisation (WHO nearly one tenth of all maternal deaths are associated with hypertensive disorders of pregnancy in Asia. The majority of deaths due to preeclampsia and eclampsia are avoidable through the provision of timely and effective care to the women presenting with these complications. Optimizing health care to prevent and treat women with hypertensive disorders is a necessary step towards achieving the Millennium Development Goals. AIMS AND OBJECTIVES The present study is aimed to evaluate thyroid function in pre-eclampsia and to compare maternal and foetal outcome in cases of pre-eclampsia with and without hypothyroidism. METHODS The study was conducted at Gandhi Hospital, Secunderabad from September 2010 to September 2012. A observational study was conducted. Hundred pregnant women meeting the criteria of preeclampsia and eclampsia presenting to antenatal ward, delivery room and high risk unit in the third trimester were selected and compared to hundred normotensive pregnant women in the third trimester. RESULTS In the present study, thyroid stimulating hormone levels were raised in 38 % of pre-eclampsia cases compared to 14% of normotensive cases (P value 3 mIU/L had more complications compared to pre-eclamptic patients with TSH < 3 mIU/L. CONCLUSION Pre-eclampsia is associated with hypothyroidism. Pre-eclamptic patients with raised thyroid stimulating hormone levels had poor maternal and foetal outcome compared to those with normal levels. Thyroid Function tests must be done in all pre-eclampsia cases. Therefore, identification of thyroid abnormalities and appropriate measures might affect the occurrence and severity of the morbidity and mortality associated with pre-eclampsia.

  13. Pre-produsage and the remediation of virtual products

    Science.gov (United States)

    Skågeby, Jörgen

    2011-04-01

    This paper introduces and explores cycles of pre-produsage and produsage. It reports on the results from an online ethnographical study of the Apple iPad conducted before the public release of the material product. Consequently, most users had not physically interacted with the device in question. Nevertheless, the release of the technical specifications and marketing material generated a massive amount of produsage-related online discussion. As such this paper explores the concept of pre-produsage. Pre-produsage is a form of predicted or expected use, relating to products or services that are only accessible to users as a form of representation (e.g. technical specification, virtual prototype, and design sketch), but with an added element of user-generated design suggestions, conflict coordination, and software development. Remediation-the process by which new digital media technologies reuses qualities of previous technologies and enters an existing media ecology-is a prevalent theme in pre-produsage and involves a tension between features that support protracted use and features that provide total innovation. The paper argues that an analysis of pre-produsage can provide insights that relate to both anticipated and actual user experience (UX). More specifically, pre-produsage analysis can trace the underlying reasons for a certain problem, intention, or concern and connect it to a specific set of features and potential solutions. Finally, the paper shows how proprietary products become subject to produsage, resulting in artifacts negotiated by cycles of produsage.

  14. Cache Scheme Based on Pre-Fetch Operation in ICN.

    Directory of Open Access Journals (Sweden)

    Jie Duan

    Full Text Available Many recent researches focus on ICN (Information-Centric Network, in which named content becomes the first citizen instead of end-host. In ICN, Named content can be further divided into many small sized chunks, and chunk-based communication has merits over content-based communication. The universal in-network cache is one of the fundamental infrastructures for ICN. In this work, a chunk-level cache mechanism based on pre-fetch operation is proposed. The main idea is that, routers with cache store should pre-fetch and cache the next chunks which may be accessed in the near future according to received requests and cache policy for reducing the users' perceived latency. Two pre-fetch driven modes are present to answer when and how to pre-fetch. The LRU (Least Recently Used is employed for the cache replacement. Simulation results show that the average user perceived latency and hops can be decreased by employed this cache mechanism based on pre-fetch operation. Furthermore, we also demonstrate that the results are influenced by many factors, such as the cache capacity, Zipf parameters and pre-fetch window size.

  18. An anaesthetic pre-operative assessment clinic reduces pre-operative inpatient stay in patients requiring major vascular surgery.

    LENUS (Irish Health Repository)

    O'Connor, D B

    2012-02-01

    BACKGROUND: Patients undergoing major vascular surgery (MVS) require extensive anaesthetic assessment. This can require extended pre-operative stays. AIMS: We investigated whether a newly established anaesthetic pre-operative assessment clinic (PAC) would reduce the pre-operative inpatient stay, avoid unnecessary investigations and facilitate day before surgery (DBS) admissions for patients undergoing MVS. PATIENT AND METHODS: One year following and preceding the establishment of the PAC the records of patients undergoing open or endovascular aortic aneurysm repair, carotid endarterectomy and infra-inguinal bypass were reviewed to measure pre-operative length of stay (LoS). RESULTS: Pre-operative LoS was significantly reduced in the study period (1.85 vs. 4.2 days, respectively, P < 0.0001). Only 12 out of 61 patients in 2007 were admitted on the DBS and this increased to 33 out of 63 patients (P = 0.0002). No procedure was cancelled for medical reasons. CONCLUSION: The PAC has facilitated accurate outpatient anaesthetic assessment for patients requiring MVS. The pre-operative in-patient stay has been significantly reduced.

  19. Pre-service teachers’ awareness of child abuse

    Nihal TUNCA

    2015-12-01

    Full Text Available The purpose of this study is to determine the awareness of pre-service teachers from different departments related to the concept of child abuse. This study aims to determine pre-service teachers’ awareness of child abuse as a qualitative study, conducted in line with phenomenological design. In the study, one of the purposeful sampling methods, maximum diversity sampling method, was employed. The participants of the study are 15 pre-service teachers attending the departments of Psychological Counseling and Guidance, Teacher Education for the Intellectually Disabled, Pre-school Teacher Education, Social Studies, Art Teaching, Computer and Instructional Technologies, German Language Teaching, French Language Teaching, and Teacher Education for the Hearing Impaired, all within the Education Faculty of Anatolian University, Turkey. The data of the study was collected through the focus-group interview technique. The data collected from two different focus-group interviews were analyzed by content analysis technique using the NVivo 8 data analysis program. As a result of the analysis of the data, it was concluded that the pre-service teachers explained the concept of child abuse by most strongly emphasizing emotional abuse and least strongly by emphasizing economic abuse. In light of the pre-service teachers’ opinions, it was also concluded that the culture constructed by society through the meanings attached to genders, society’s view of sexuality, child marriage, proverbs and idioms specific to the local society and superstitions lead to incidences of child abuse. The current study revealed that child abuse can be prevented by providing training to raise the awareness of child abuse primarily for families then children, teachers and other concerned people. It was also found that the majority of pre-service teachers do not have enough information about how to act in the face of an incidence of child abuse.

  20. Dynamics of Pre-3 Ga Crust-Mantle Evolution

    Science.gov (United States)

    Patchett, P. J.; Chase, C. G.; Vervoort, J. D.

    2004-05-01

    During 3.0 to 2.7 Ga, the Earth's crust underwent a non-uniformitarian change from a pre-3.0 Ga environment where long-term preservation of cratons was rare and difficult, to post-2.7 Ga conditions where cratons were established and new continental crust generation took place largely at craton margins. Many models view the Earth's surface during pre-3 Ga time as broadly equivalent to the post 2.7 Ga regime. Any such uniformitarian or gradual evolution cannot explain the conundrum that only a tiny amount of pre-3 Ga crust is preserved today coupled with the fact that very little pre-3 Ga crust was incorporated into the large amount of new craton that came into existence during 3.0-2.7 Ga. If large volumes of pre-3 Ga continental crust existed, it disappeared either just prior to 3 Ga, or during 3.0-2.7 Ga. To explain sudden appearance of surviving but dominantly juvenile continental crust in a model where continents were large prior to 3 Ga, it would be necessary either that pre-3 Ga continent was recycled into the mantle at sites systematically different from those where new 3.0-2.7 Ga crust was made, or that widespread continent destruction preceded the 3.0-2.7 Ga crustal genesis. From expected mantle overturn in response to the heat budget, it is likely that most pre-3 Ga crust was both more mafic and shorter-lived than after 3 Ga. Although Nd and Hf ratios for pre-3 Ga rocks are uncertain due to polymetamorphism, it appears that depleted upper mantle was widespread by 2.7 Ga, even pre-3 Ga. Depletion may have been largely achieved by formation, subduction and storage of mafic crust for periods of 200-500 m.y. The rapid change to large surviving continents during 3.0-2.7 Ga was due to declining mantle overturn, and particularly to development of the ability to maintain subduction in one zone of the earth's surface for the time needed to allow evolution to felsic igneous rock compositions. In as much as storage of subducted slabs is probably occurring today, and

  1. THE HABITABLE ZONES OF PRE-MAIN-SEQUENCE STARS

    Energy Technology Data Exchange (ETDEWEB)

    Ramirez, Ramses M.; Kaltenegger, Lisa [Institute for Pale Blue Dots, Cornell University, Ithaca, NY (United States)

    2014-12-20

    We calculate the pre-main-sequence habitable zone (HZ) for stars of spectral classes F-M. The spatial distribution of liquid water and its change during the pre-main-sequence phase of protoplanetary systems is important for understanding how planets become habitable. Such worlds are interesting targets for future missions because the coolest stars could provide habitable conditions for up to 2.5 billion years post-accretion. Moreover, for a given star type, planetary systems are more easily resolved because of higher pre-main-sequence stellar luminosities, resulting in larger planet-star separation for cool stars than is the case for the traditional main-sequence (MS) HZ. We use one-dimensional radiative-convective climate and stellar evolutionary models to calculate pre-main-sequence HZ distances for F1-M8 stellar types. We also show that accreting planets that are later located in the traditional MS HZ orbiting stars cooler than a K5 (including the full range of M stars) receive stellar fluxes that exceed the runaway greenhouse threshold, and thus may lose substantial amounts of water initially delivered to them. We predict that M-star planets need to initially accrete more water than Earth did, or, alternatively, have additional water delivered later during the long pre-MS phase to remain habitable. Our findings are also consistent with recent claims that Venus lost its water during accretion.

    2013-01-01

    The study objective was to determine the prevalence of diabetes and prediabetes among rural and urban populations in Kansas. This study utilized 2009 BRFSS data and included 18,912 respondents. Participants were identified through a stratified random sample of adult Kansans, living in a non-institutionalized setting, and with access to a land-based telephone line. Analyses were conducted using SAS to provide descriptive statistics for groups based on diabetes status. A logistic regression was conducted to explore significant variables associated with the likelihood of diabetes. Diabetes prevalence was lower among urban (11.8%) populations than rural (12.7%) areas of Kansas, but the inverse was true for pre-diabetes (3.7% urban, 3.1% in rural). Lower income and lower levels of educational attainment were associated with increased rates of diabetes and pre-diabetes, with the highest prevalence levels overall found among rural Latinos (19.3%) and urban African Americans (22.9%). Multivariate regression suggests that age, income, ethnicity, education, sex, rural vs urban status, and race all served as significant predicators of diabetes, net of other factors. Rural residents were more likely than urban residents to report having diabetes, whereas urban residents were more likely than rural residents to report having pre-diabetes. Although rural vs urban status played a significant role in the model's predicative ability for diabetes and pre-diabetes diagnosis, increased age was by far the most significant factor in diabetes and pre-diabetes diagnosis.

    This paper introduces a novel approach to constructing an effective pre-conditioner for finite-difference (FD) electromagnetic modelling in geophysical applications. This approach is based on introducing an FD contraction operator, similar to one developed for integral equation formulation of Maxwell's equation. The properties of the FD contraction operator were established using an FD analogue of the energy equality for the anomalous electromagnetic field. A new pre-conditioner uses a discrete Green's function of a 1-D layered background conductivity. We also developed the formulae for an estimation of the condition number of the system of FD equations pre-conditioned with the introduced FD contraction operator. Based on this estimation, we have established that the condition number is bounded by the maximum conductivity contrast between the background conductivity and actual conductivity. When there are both resistive and conductive anomalies relative to the background, the new pre-conditioner is advantageous over using the 1-D discrete Green's function directly. In our numerical experiments with both resistive and conductive anomalies, for a land geoelectrical model with 1:10 contrast, the method accelerates convergence of an iterative method (BiCGStab) by factors of 2-2.5, and in a marine example with 1:50 contrast, by a factor of 4.6, compared to direct use of the discrete 1-D Green's function as a pre-conditioner.

    Full Text Available The purpose of the present study is to determine pre-service teachers‟ opinions on teaching thinking skills. 134 senior pre-service pre-school, English and mathematics teachers studying at a state university in Istanbul participated in the study which is designed based on survey model. A questionnaire which was developed by the researchers was used in data collection and percentage and frequency values were calculated for the data analysis. The results showed that preservice teachers thought that thinking skills could be taught and teaching thinking skills should begin in pre-school level. They regarded the mixed approach as the most effective approach in teaching thinking skills. They considered that teachers‟ and administrators‟ modeling were considerably important in thinking-friendly classrooms and schools. They believed that being open to different opinions was the most important attribute of teachers who promote thinking. Pre-service teachers perceive themselves partially competent in developing students‟ thinking skills in the future. However, they emphasized the need for training in teaching thinking skills at schools

    There are several treatment proposals for the obstetric patient with pre-eclampsia, but there is limited evidence on the adequacy of standard treatment. International healthcare organisations recommend that hospitals or anaesthesia departments have written guidelines, protocols or recommendations for dealing with common or severe situations. We propose evidence-based recommendations for the treatment of pre-eclampsia. A literature review was performed using several sources, bibliography databases, recommendations made by specialist societies, and reviews. Four anaesthesiologists reviewed the references selected, in order to design clinical questions (these were obtained from recent pre-eclampsia review articles). Consensus of at least 3 out of 4 experts was required. The Oxford criteria for evidence were chosen to classify the scientific articles, and the Jadad score was applied to the final articles selected. A total of 50 clinical questions were designed and answered. These were classified into: general questions, influence of the type of delivery, pre-anaesthesia evaluation, peripartum treatment (including analgesia and anaesthesia), eclampsia, post-delivery period, and intensive care and transport. Most of the responses showed low scientific evidence. Evidence-based recommendations for severe pre-eclampsia treatment were provided with special emphasis on the anaesthesiologist point of view.

    2015-11-01

    Mood is a moderating factor that is known to affect performance. For airlines, the delivery of the pre-flight safety briefing prior to a commercial flight is not only an opportunity to inform passengers about the safety features on-board the aircraft they are flying, but an opportunity to positively influence their mood, and hence performance in the unlikely event of an emergency. The present research examined whether indeed the pre-flight safety briefing could be used to positively impact passengers' mood. In addition, the present research examined whether the recall of key safety messages contained within the pre-flight safety briefing was influenced by the style of briefing. Eighty-two participants were recruited for the research and divided into three groups; each group exposed to a different pre-flight cabin safety briefing video (standard, humorous, movie theme). Mood was measured prior and post safety briefing. The results revealed that pre-flight safety briefing videos can be used to manipulate passengers' mood. Safety briefings that are humorous or use movie themes to model their briefing were found to positively affect mood. However, there was a trade-off between entertainment and education, the greater the entertainment value, the poorer the retention of key safety messages. The results of the research are discussed from both an applied and theoretical perspective.

  7. Biologically Pre-Treated Habitation Waste Water as a Sustainable Green Urine Pre-Treat Solution

    The ability to recover water from urine and flush water is a critical process to allow long term sustainable human habitation in space or bases on the moon or mars. Organic N present as urea or similar compounds can hydrolyze producing free ammonia. This reaction results in an increase in the pH converting ammonium to ammonia which is volatile and not removed by distillation. The increase in pH will also cause precipitation reactions to occur. In order to prevent this, urine on ISS is combined with a pretreat solution. While use of a pretreatment solution has been successful, there are numerous draw backs including: storage and use of highly hazardous solutions, limitations on water recovery (less than 85%), and production of brine with pore dewatering characteristics. We evaluated the use of biologically treated habitation wastewaters (ISS and early planetary base) to replace the current pretreat solution. We evaluated both amended and un-amended bioreactor effluent. For the amended effluent, we evaluated "green" pretreat chemicals including citric acid and citric acid amended with benzoic acid. We used a mock urine/air separator modeled after the urine collection assembly on ISS. The urine/air separator was challenged continually for >6 months. Depending on the test point, the separator was challenged daily with donated urine and flushed with amended or un-amended reactor effluent. We monitored the pH of the urine, flush solution and residual pH in the urine/air separator after each urine event. We also evaluated solids production and biological growth. Our results support the use of both un-amended and amended bioreactor effluent to maintain the operability of the urine /air separator. The ability to use bioreactor effluent could decrease consumable cost, reduce hazards associated with current pre-treat chemicals, allow other membrane based desalination processes to be utilized, and improve brine characteristics.

    Full Text Available The paper provides the framework supporting the training of educative agents to influence upon sexual education of boys and girls in pre-school age as a way to attain high quality standard in the education. These rationale starts from the assumption that it is possible to favor the training process of educative agents on the topic by means of integrating actions with a gender centered approach. The proposal is the result of a thorough study based on the socio-historical cultural approach resulting from the doctoral dissertation already presented by the first authoress. At the same time, these results contribute to the research project “Training the family for the intellectual stimulus of pre-school children. Additionally it offers the stages of sexual education at pre-school age.

    As in reading teaching, schema theory has long been taking a dominant part. According to this theory, English teachers can help the students to call up their prior knowledge by placing an emphasis on a more efficient use of pre-reading activities. One of the effective activities is to make good use of the pre-reading exercises in the textbook. This paper intends to analyze the results of two brief investigations. One was about the pre-reading exercises in the SEFC (New Edition 2010) Book 1 . The other was car⁃ried out among the first year students from Nanhai Experimental High School of South China Normal University. English teachers in high school thus can train the students to make links between the text and what they already know according to their interests.

  10. Management of pain in pre-hospital settings.

    2015-06-01

    Assessment and management of pain in pre-hospital care settings are important aspects of paramedic and clinical team roles. As emergency department waiting times and delays in paramedic-to-nurse handover increase, it becomes more and more vital that patients receive adequate pre-hospital pain relief. However, administration of analgesia can be inadequate and can result in patients experiencing oligoanalgesia, or under-treated pain. This article examines these issues along with the aetiology of trauma and the related socioeconomic background of traumatic injury. It reviews validated pain-assessment tools, outlines physiological responses to traumatic pain and discusses some of the misconceptions about the provision of effective analgesia in pre-hospital settings.

    2001-11-01

    Before the demographic transition in Thailand, fertility was high, but not uniformly so. As in other pre-transition settings, Thai fertility responded to pressures and opportunities created by socioeconomic structure and land availability. Drawing upon provincial data from the 1947 and 1960 censuses of Thailand, we find a strong 'frontier effect' on Thai fertility in the 1950s. Fertility was higher in sparsely settled frontier provinces and lower in provinces with higher population density relative to cultivatable land. This finding is robust and holds up with controls for agricultural employment, land quality, and the sex ratio (an indicator of sex-selective migration). The effect of population pressure lowers the likelihood of marriage and of marital fertility. The findings from Thailand are consistent with the research of Easterlin on the nineteenth century United States and with other pre-transition societies. We suggest how demographic transition theory might be broadened to include fertility dynamics in pre-transition societies.

    2011-01-01

    The China Spallation Neutron Source (CSNS) front end incorporates a pre-chopper in the Low Energy Beam Transport line (LEBT) that will remove a 530 ns section of beam at approximately 1 MHz rate, which is the RF frequency of the ring at injection. It’s one of the most critical devices for properly controlling the injecting beam loss. Physical designing of the pre-chopper is carried out, and the RFQ itself is used as the beam dump of the chopper system. In order to examine the reliability of the pre-chopper design, the beam study of a similar chopper system is successfully performed. The results of physical design and experiments are presented.

    In recent years, it has been shown that groundwater with a Pre-Holocene component is more common in the Icelandic bedrock than previously thought. Some of the Pre-Holocene water samples are more depleted in delta H-2 and delta O-18 than any mean annual precipitation in Iceland today due to the cold......-Holocene component in the groundwater. The deuterium excess value may also help to identify water from a different climate regime, if no oxygen shift has occurred. The relative abundance of a Pre-Holocene water component of the Icelandic groundwater has led to the understanding that combined interpretation of water......-isotopes, water chemistry and hydrogeology is essential to delineate flow direction and trace the origin of thermal and non-thermal groundwaters....

    Our aim was to assess the basic musculoskeletal competency of pre-internship graduates from Nigerian medical schools. We administered the Freedman and Bernstein basic musculoskeletal competency examination to 113 pre-internship graduates from seven Nigerian medical schools over a three year period from 2008 to 2010 at the University of Uyo Teaching Hospital. Five specialist residents took the examination to test criteria relevance. All graduates failed this test, obtaining scores ranging from 7% to 67%. The duration of the orthopaedic posting, and observation of operative fracture fixation, were not significant determinants of the score. The two final-year specialist residents each had a marginal pass in the examination. Basic musculoskeletal competency among pre-internship Nigerian medical-school graduates is inadequate.

    Full Text Available Through this research, it has been aimed to determine the perceptions, opinions and ideas of pre-service elementary teachers about global warming which is an environmental problem that threatens the world. This research was applied to 10 pre-service elementary teachers. The data in the research were collected through face-to-face oral interviews. Collected qualitative data were analyzed with descriptive analysis technique. According to the results of the research, it was observed that pre-service teachers worried about the possible outcomesof global warming and were not equipped with sufficient information about environmental problems. It was concluded that preservice teachers established the false cause-effect relationship between the environmental problems such as greenhouse effect, ozone layer problem, acid rain.

  17. Undiagnosed Diabetes and Pre-Diabetes in Health Disparities.

    Full Text Available Globally half of all diabetes mellitus is undiagnosed. We sought to determine the extent and characteristics of undiagnosed type 2 diabetes mellitus and pre-diabetes in Mexican Americans residing in the United States. This disadvantaged population with 50% lifetime risk of diabetes is a microcosm of the current pandemic. We accessed baseline data between 2004 and 2014 from 2,838 adults recruited to our Cameron County Hispanic Cohort (CCHC; a two-stage randomly selected 'Framingham-like' cohort of Mexican Americans on the US Mexico border with severe health disparities. We examined prevalence, risk factors and metabolic health in diagnosed and undiagnosed diabetes and pre-diabetes. Two thirds of this Mexican American population has diabetes or pre-diabetes. Diabetes prevalence was 28.0%, nearly half undiagnosed, and pre-diabetes 31.6%. Mean BMI among those with diabetes was 33.5 kg/m2 compared with 29.0 kg/m2 for those without diabetes. Significant risk factors were low income and educational levels. Most with diabetes had increased waist/hip ratio. Lack of insurance and access to health services played a decisive role in failure to have diabetes diagnosed. Participants with undiagnosed diabetes and pre-diabetes had similar measures of poor metabolic health similar but generally not as severe as those with diagnosed diabetes. More than 50% of a minority Mexican American population in South Texas has diabetes or pre-diabetes and is metabolically unhealthy. Only a third of diabetes cases were diagnosed. Sustained efforts are imperative to identify, diagnose and treat individuals in underserved communities.

    To evaluate the state and level of pre-clinical endodontic education in German dental schools and to evaluate differences with regard to intensity and extent of teaching, time devoted to teaching pre-clinical endodontics, personnel resources in teaching and technical equipment. Twenty-eight questionnaires were e-mailed to those in charge of pre-clinical endodontic education in German dental schools. The extent of education, the student-teacher ratio, the teaching content as well as the application of teaching materials and technologies were asked. If, after 4 weeks, no response had been received, the questionnaire was sent out by e-mail again. In the absence of a reply, a phone call was made to the corresponding university to conduct the survey by phone. With feedback from 27 of 28 dental schools, the response rate was 96%. Pre-clinical endodontic education at German universities varied considerably. Theory classes ranged from 5 to 30 h (13.3 h mean), practical classes from 12.5 to 60 h (45.4 h mean). The student to staff ratio varied between 9 : 1 and 30 : 1 (16 : 1 mean). Forty-eight per cent of the universities had a specialist in endodontics or a teacher with a special interest. A dental microscope was available for pre-clinical teaching purposes in 38% of the universities. The majority (63%) of universities taught root canal preparation with rotary nickel titanium instruments. Pre-clinical endodontic education varied considerably between German universities because of differences in programme design, staff and course content.

    Creosotebush [Larrea tridentata (D.C.) Cav.] and white bursage [Ambrosia dumosa (A. Gray) W.W. Payne] seeds were subjected to pre-treatments of rinsing and soaking in water and thiourea to enhance germination in laboratory experiments. The effects of darkness, temperature, seed source, and soil moisture were also evaluated in the laboratory. The best pre-treatment from the laboratory experiments, rinsing with water for 36 hours followed by drying, was field-tested at Fort Irwin, California. Two sites and two seeding dates (early March and mid April) were determined for each site. Five mulch treatments (no mulch, straw, gravel, chemical stabilizer, and plastic) were evaluated in combination with the seed pre-treatments. Field emergence was greatly enhanced with the seed pre-treatment for white bursage during the March (18-42% increase in germination) and April seedings (16-23% increase in germination). Creosotebush showed poor germination during March (2-5%) when soil temperatures averaged 15 C, but germination increased during the April trials (6-43%) when soil temperatures averaged 23 C. The seed pre-treatment during the April trials increased germination from 16-23%. The plastic mulch treatment increased germination dramatically during both the March and April trials. The plastic mulch increased soil temperatures (8-10 C)and maintained high humidity during germination. Both the chemical stabilizer and the gravel mulches improved germination over the control while the straw mulch decreased germination. These results suggest that seed pre-treatments combined with irrigation and mulch are effective techniques to establish these two dominant Mojave Desert species from seed.

    Pre-β1 HDL, being a major acceptor of free cholesterol from cells, plays an important role in reverse cholesterol transport. This study was performed to determine whether abnormalities in pre-β1 HDL concentration were present in type 2 diabetes irrespective of their HDL-cholesterol levels, and the impact on cholesterol efflux. 640 type 2 diabetic patients with or without cardiovascular disease (CVD) and 360 non-diabetic controls matched for serum HDL-cholesterol levels were recruited. Plasma pre-β1 HDL was measured by ELISA, and cholesterol efflux to serum, mediated by ATP-binding cassette transporter A1 (ABCA1), was determined by measuring the transfer of [3H]cholesterol from cultured cells expressing ABCA1 to the medium containing the tested serum. Despite the diabetic subjects having matched HDL-cholesterol and total apoA1 as controls, plasma pre-β1 HDL was significantly reduced in both male (p diabetic patients (p HDL level. Serum capacity to induce ABCA1-mediated cholesterol efflux was impaired in the diabetic group (p HDL (Pearson's r = 0.38, p diabetes status, smoking, apoA1, triglyceride and LDL. Plasma pre-β1 HDL level was significantly decreased in type 2 diabetes and was associated with a reduction in cholesterol efflux mediated by ABCA1. Our data would suggest that low pre-β1 HDL might cause impairment in reverse cholesterol transport in type 2 diabetes. Copyright © 2017 Elsevier B.V. All rights reserved.

    Full Text Available Previous studies have suggested that ketamine, an N-methyl-D-aspartate (NMDA receptor antagonist, provides a pre-emptive analgesic effect and pre-emptive analgesia improves postoperative pain management. The aim of this study was to determine the effict of pre-incisional vs. post-incisional intravenous low dose of racemic ketamine in postoperative pain in children undergoing inguinal hernia repair. Seventy-five children aged 1-6 years who were scheduled for inguinal herniorrhaphy were included in a prospective, double-blind randomized controlled trial. Patients were randomly allocated to three groups (pre-incisional, post-incisional and control. Patients in pre-incisional group received an intravenous bolus of racemic ketamine (0.25 mg/kg before surgical incision and patients in post-incisional group received the same dose of racemic ketamine after surgical incision. Children of control group received intravenous boluses of normal saline. In post anesthesia care unit and pediatric surgical ward, the degree of pain and sedation, additional analgesic requirements and side effects were evaluated. There were no differences between groups with respect to demographic and hemodynamic parameters. Pain and sedation scores were not statistically different between groups during 24 h study. In addition, there was no significant difference among groups in number of supplementary analgesic requirements and postoperative nausea and vomiting in the first 24 h. No other side effects were reported during the study period. We found that low dose racemic ketamine administered prior to surgical incision has no pre-emptive effect on post-operative pain and supplementary analgesic requirement during the first 24 h after herniorrhaphy in pediatric patients.

    2015-10-01

    The impact of laboratory medicine on clinical cardiology has dramatically increased over the years and a lot of cardiovascular biomarkers have been recently proposed. In order to avoid clinical mistakes, physicians should be well aware of all the aspects, which could affect the quality of laboratory results, remembering that pre-analytic variability is an often overlooked significant source of bias, determining the vast majority of laboratory errors. This review addresses the determinants of pre-analitycal variability in cardiovascular biomarker testing, focusing on the most widespread biomarkers, which are cardiac troponins and natriuretic peptides.

    Pre-clinical positron emission tomography (PET) has evolved in the last few years from pure visualization of radiotracer uptake and distribution towards quantification of the physiological parameters. For reliable and reproducible quantification the kinetic modeling methods used to obtain relevant parameters of radiotracer tissue interaction are important. Here we present different kinetic modeling techniques with a focus on compartmental models including plasma input models and reference tissue input models. The experimental challenges of deriving the plasma input function in rodents and the effect of anesthesia are discussed. Finally, in vivo application of kinetic modeling in various areas of pre-clinical research is presented and compared to human data.

    The barrel survey results from the pre-assembly in Building 185 are reviewed. From these and the models developed to calculate the cylinder geometry we propose a minimal modification to the shimming plan for the barrel calorimeter assembly in the Atlas cavern. At the precision of this calculation, we expect the tile calorimeter to be almost entirely within it design envelope. The focus of this note is the radial envelope. Based on the pre-assembly experience the tile calorimeter will fit comfortably within its envelope along the beam line.

    Kwok, James Tin-yau; Tsang, Ivor Wai-hung

    2004-11-01

    In this paper, we address the problem of finding the pre-image of a feature vector in the feature space induced by a kernel. This is of central importance in some kernel applications, such as on using kernel principal component analysis (PCA) for image denoising. Unlike the traditional method which relies on nonlinear optimization, our proposed method directly finds the location of the pre-image based on distance constraints in the feature space. It is noniterative, involves only linear algebra and does not suffer from numerical instability or local minimum problems. Evaluations on performing kernel PCA and kernel clustering on the USPS data set show much improved performance.

    1984-01-01

    The detection limits of drugs in quantitative RRA are primarily determined by their affinities towards the receptor. Yet, the concentration of radiolabeled ligand, necessary for quantification of receptor-bound drug, increases the theoretical detection limit. Therefore the influences of low temperatures and pre-incubation on the detection limit was studied. Analysis of experimental data suggests that when a well-defined incubation procedure is used, pre-incubation and low temperatures will increase sensitivity without loss of accuracy and precision. 6 references, 2 figures.

    2012-08-01

    Pre-eruptive intra-coronal radiolucency (PEIR) describes a radiolucent lesion located in the coronal dentine, just beneath the enamel-dentine junction of unerupted teeth. The prevalence of this lesion varies depending on the type and quality of radiographic exposure and age of patients used for assessment. The aetiology of pre-eruptive intra-coronal radiolucent lesions is not fully understood, but published clinical and histological evidence suggest that these lesions are resorptive in nature. Issues around the diagnosis, treatment planning and clinical management of this lesion are explored using previously unreported cases.

    Full Text Available Abstract Objectives It is unknown if telbivudine causes muscle damage only in patients with pre-existing muscle pathology. Case report A 27 yo male of African origin received telbivudine for hepatitis B during 3 months. Three weeks after initiation of the drug he developed myalgia, and tiredness. Creatine-kinase increased from 278 U/l (n, Conclusions Telbivudine appears to cause accelerated muscle toxicity if given to patients who already have muscle damage. Patients under telbivudine should be closely monitored for muscular side effects and those with pre-existing muscle damage should not receive the drug.

    2013-06-01

    Full Text Available In pre-colonial Akokoland, the most conspicuous fact about its political economy and peace was security challenges and mismanagement through internal and external manipulation. This paper analyses the role of women in warfare in pre-colonial Akokoland as a potential to integrate Akokoland, a multi-cultural community for productive and sustained effort to promote economic development in the region. Thus, the paper is conceptualised on historical objectivity. The paper argues that one of the ways of dealing with the scale of insecurity in the society is to assimilate historical thinking into the intention of the security agents (women warriors.

  17. User's Guide to PreComp (Pre-Processor for Computing Composite Blade Properties)

    Energy Technology Data Exchange (ETDEWEB)

    Bir, G. S.

    2006-01-01

    PreComp (Pre-processor for computing Composite blade structural properties) was developed to compute the stiffness and inertial properties of a composite blade. The code may also be used to compute the structural properties of a metallic blade by treating it as a special case of an isotropic composite material. This guide provides step-by-step instructions on how to prepare input files (specify blade external geometry and internal structural layup of composite laminates), how to execute the code, and how to interpret the output properties. PreComp performs extensive checks for completeness, range, and viability of input data; these are also discussed in this manual. The code runs fast, usually in a fraction of a second, and requires only a modest knowledge of the composites and laminates schedule typically used in blades.

  11. Pre-analytical phase in clinical chemistry laboratory

    Directory of Open Access Journals (Sweden)

    Neogi SS

    2016-07-01

    Full Text Available The laboratory testing process is divided into the pre-analytical, analytical and post-analytical phases. For obtaining reliable test results, the prevention and detection of errors at all steps is required. While analytical standards have been developed by recognized quality control criteria, there is a scarcity in the development of standards for the preanalytical phase. This phase is most prone to errors as the steps involved are directly dependent on humans and are out of direct control of the laboratory. Such errors in preanalytical stage often only become apparent in the analytical or post-analytical phase. The development of a pre-analytical quality manual is essential in achieving total quality control. Correct practices and strategies of error prevention can reduce preanalytical errors. This review focuses on prevention of pre-analytical errors that occur while collecting a specimen of blood, urine and cerebrospinal fluid. Most of these can be easily prevented with understanding and education of the personnel involved in and responsible for executing this crucial pre-analytical phase.

  14. FUNCTIONALLY UNIVENTRICULAR HEARTS: IMPACT OF PRE-NATAL DIAGNOSIS

    Directory of Open Access Journals (Sweden)

    Antonio Francesco Corno

    2015-02-01

    Full Text Available Within the last few decades the pre-natal echocardiographic diagnosis of congenital heart defects has made substantial progresses, particularly for the identification of complex malformation. Functionally univentricular hearts categorize a huge variety of heart malformations. Since no one of the patients with these congenital heart defects can ever undergo a bi-ventricular type of repair, early recognition and decision-making from the neonatal period are required in order to allow for appropriate multiple-step diagnostic and treatment procedures, either of interventional cardiology and/or surgery, on the pathway of univentricular heart. In the literature strong disagreements exist about the potential impact of the pre-natal diagnosis on the early and late outcomes of complex congenital heart defects. This review of the recent reports has been undertaken to better understand the impact of pre-natal diagnosis in functionally univentricular hearts taking into consideration the following topics:•pre-natal screening•outcomes and survival•general morbidity•neurologic and developmental consequences•pregnancy management and delivery planning•resources utilization and costs/benefits issues•ethical implications, parents counseling, interruption of pregnancy versus treatment

  17. Pre-Service Teachers Methods of Teaching Science

    Directory of Open Access Journals (Sweden)

    Dr. Raquel C. Pambid

    2015-02-01

    Full Text Available The study described the teaching methods used by pre-service teachers in Science. It focused on the strategies, techniques, materials, innovative methods and pattern of teaching science used by the pre-service teachers as described in their lesson plans. The qualitative and quantitative design was used in the study. The books, teacher hand-outs from classroom lectures were the sources of methods, strategies and techniques. The chalkboard and self-made drawings and charts were the materials often used. Conventional methods like lecture, open class discussion and demonstration were commonly employed. The strategies included group discussion, use of motivating questions and stories to arouse the interest of students. The direct eye contact, body expressions, jokes and news/trivia were frequent techniques. Integration of values in the lesson became less as the year level increases. The pattern of teaching drawn followed the formal style: I Objectives, II Subject matter, III Learning Tasks, IV Synthesis of the lesson, V Assessment and VI Enrichment. The conventional method and pattern of teaching by the pre-service teachers of PSU suggest that students in the College of Teacher Education should be trained to be more innovative and open in trying out more advanced teaching methods. Furthermore, PSU science pre-service teachers should use methods which can develop higher order thinking skills among high school students.

  18. Intelligence: Pre-Theory and Post-Theory

    Directory of Open Access Journals (Sweden)

    James R. Flynn

    2014-02-01

    Full Text Available Defining “intelligence” exemplifies a mistake that has historical precedent: confusing the role of pre-theory and post-theory definitions. In every area, pre-theory concepts give broad directions for investigation: are the movements of heavenly bodies affected by the existence of other heavenly bodies? Post-theory concepts add precision and predictability. The mistake occurs when a successful theory like Newton’s demands that its peculiar and precise theory-imbedded concept forbids competing theories: Einstein was impossible (warping of space so long as it was assumed that all theories must be in accord with Newton’s concept (attraction across space. In psychology, Arthur Jensen made the same mistake. He gave his theory-embedded concept of g the role of executioner: the significance of every phenomenon had to be interpreted by its compatibility with g; and thus trivialized the significance of IQ gains over time. This is only one instance of a perennial demand: give us a precise definition of “intelligence” to guide our research. However, precision comes after research has generated a theory and its very precision stifles competing research. Be happy with a broad definition on the pre-theory level that lets many competing theories bloom: pre-theory precision equals post-theory poverty.

    2010-01-01

    Full Text Available This study investigated the effect of attending pre-school on mucosal immunity. Children 3.5 to 5 years of age who attended pre-school were observed for a 10 month period. Demographic information was collected on previous childcare experiences, the home environment and clinical information relating to the child and the family. A daily illness log was kept for each child. A multivariate longitudinal analysis of the relation between immunoglobulins in saliva and age, gender, childcare experience, pre-school exposure, number of siblings, environmental tobacco smoke (ETS, atopy and hospitalisation was conducted. There was a positive association of higher IgA levels with the winter season and with children being older than 4 years (<.001, having attended childcare prior to commencing pre-school (<.05, and having been exposed to ETS at home (<.05. Lower IgA levels were associated with being atopic (<.05. Higher IgG levels were associated with exposure to ETS (<.001, while lower levels were associated to having atopy. Higher IgM levels were associated with previous childcare experience (<.01 whilst having been hospitalised was associated with having low salivary IgM levels (<.01. Lagged analyses demonstrated that immunological parameters were affected by the number of respiratory infections in the preceding 2 months.

  3. MBL Interferes with Endovascular Trophoblast Invasion in Pre-Eclampsia

    Directory of Open Access Journals (Sweden)

    Chiara Agostinis

    2012-01-01

    Full Text Available The spiral arteries undergo physiologic changes during pregnancy, and the failure of this process may lead to a spectrum of pregnancy disorders, including pre-eclampsia. Our recent data indicate that decidual endothelial cells (DECs, covering the inner side of the spiral arteries, acquire the ability to synthesize C1q, which acts as a link between endovascular trophoblast and DECs favouring the process of vascular remodelling. In this study, we have shown that sera obtained from pre-eclamptic patients strongly inhibit the interaction between extravillous trophoblast (EVT and DECs, preventing endovascular invasion of trophoblast cells. We further demonstrated that mannose-binding lectin (MBL, one of the factor increased in pre-eclamptic patient sera, strongly inhibits the interaction of EVT with C1q interfering with the process of EVT adhesion to and migration through DECs. These data suggest that the increased level of MBL in pre-eclampsia may contribute to the failure of the endovascular invasion of trophoblast cells.

    Nowadays statistical graphs has been widely used as a medium to communicate. Awareness of the important of statistical graphs have been realized by Ministry of Education. Therefore, Ministry of Education have included this topic into national standard curriculum as early as Standard 3. It proved that this field of study is important to our students. However pre-service teachers still faced some difficulties to comprehend various types of statistical graphs. Among the problem faced by those pre-service teachers are the difficulties to relate two statistical graphs that carrying related issues. Therefore this study will look at the types of difficulties faced by pre-service teachers when they need to interpret two statistical graphs which carried related issues. We focus on data which came from interviews which gives evidence of several problems faced by pre-service teachers when they try to comprehend those graphs that are related with each other. The discussion of results might contribute to an understanding of the complexity of the interpretation of such graphs, and to the possible solutions that can be used to cater on the problems arise.

  6. Modeling Burns for Pre-Cooled Skin Flame Exposure

    Directory of Open Access Journals (Sweden)

    Torgrim Log

    2017-09-01

    Full Text Available On a television show, a pre-cooled bare-skinned person (TV host passed through engulfing kerosene flames. The assumption was that a water film should protect him during 0.74 s flame exposure in an environment of 86 kW/m2 heat flux. The TV host got light burn inflammation on the back, arms and legs. The present work studies skin temperatures and burn damage integral of such dangerous flame exposure. The skin temperature distribution during water spray pre-cooling, transport to the flames, flame exposure, transport to the water pool, and final water pool cooling is modelled numerically. Details of the temperature development of the skin layers are presented, as well as the associated damage integral. It is shown that 5 °C water spray applied for a 30 s period pre-cooled the skin sufficiently to prevent severe skin injury. Soot marks indicate that the water layer evaporated completely in some areas resulting in skin flame contact. This exposed dry skin directly to the flames contributing significantly to the damage integral. It is further analyzed how higher water temperature, shorter pre-cooling period or longer flame exposure influence the damage integral. It is evident that minor changes in conditions could lead to severe burns and that high heat flux levels at the end of the exposure period are especially dangerous. This flame stunt should never be repeated.

    2017-02-01

    In order to get some information about students' knowledge structure regarding to a particular concept, the examination of understanding level is an important issue. This qualitative study investigates the understanding level of pre-service physics teachers about the subject of electric flux. 21 pre-service physics teachers, who have already taken the electric and magnetism course I, participated in the study. Semi-structured interviews were conducted with the participants. The collected data were analyzed by using the content analysis method and the understanding level of the participants about the electric flux was revealed. According to the results the pre-service physics teachers' understanding levels were determined as; two participants were in "Sound Understanding", one participant was in "Partial Understanding", 10 participants were in "Partial Understanding with Specific Alternative Conception" levels. Additionally, three participants' understanding level was determined as "No Understanding" level, because of their incorrect, irrelevant or unclear responses toward the questions. On the other hand, five participants had also some alternative conceptions about the subject of electric flux. The alternative conceptions that the pre-service physics teachers had, were mostly about the relationship between the surface and electric flux.

  9. The Ramachandran plots of glycine and pre-proline

    Directory of Open Access Journals (Sweden)

    Brasseur Robert

    2005-08-01

    Full Text Available Abstract Background The Ramachandran plot is a fundamental tool in the analysis of protein structures. Of the 4 basic types of Ramachandran plots, the interactions that determine the generic and proline Ramachandran plots are well understood. The interactions of the glycine and pre-proline Ramachandran plots are not. Results In glycine, the ψ angle is typically clustered at ψ = 180° and ψ = 0°. We show that these clusters correspond to conformations where either the Ni+1 or O atom is sandwiched between the two Hα atoms of glycine. We show that the shape of the 5 distinct regions of density (the α, αL, βS, βP and βPR regions can be reproduced with electrostatic dipole-dipole interactions. In pre-proline, we analyse the origin of the ζ region of the Ramachandran plot, a region unique to pre-proline. We show that it is stabilized by a COi-1···CδHδi+1 weak hydrogen bond. This is analogous to the COi-1···NHi+1 hydrogen bond that stabilizes the γ region in the generic Ramachandran plot. Conclusion We have identified the specific interactions that affect the backbone of glycine and pre-proline. Knowledge of these interactions will improve current force-fields, and help understand structural motifs containing these residues.

    Full Text Available Nowadays communities are continuously evolving and changing socially, economically and culturally. Technology is certainly at the top of causative agent of development and change. The opportunities offered by technology especially in education accelerating this development. In recent years rapidly progress of training technology has led to use computers in education. It's a fact that audio-visual support provided by computers is efficient in pre-school children's education. But in pre-school period children don't know how to read and write and haven't completed their small muscle development, this fact limits the use of computers in the process. However, speech recognition technologies which is one of the opportunities offered by technology, is the solution to overcome this limitations. Speech recognition technologies are the systems, that developed for the recognition of sounds by computers are perceived by the devices like microphone. In this study with the facilities of speech recognition technology, supporting individual learning in pre-school education has been aimed. For this reason an educational software in which this technologies of speech recognition are integrated for the usage of pre-school education has been prepared. The most distinctive characteristic of this software is to be able to used with completely sounds. Thus, this software can be used easily by the children who can not to use their hands and arms.

  4. On pre-image iterations for speech enhancement.

    Science.gov (United States)

    Leitner, Christina; Pernkopf, Franz

    2015-01-01

    In this paper, we apply kernel PCA for speech enhancement and derive pre-image iterations for speech enhancement. Both methods make use of a Gaussian kernel. The kernel variance serves as tuning parameter that has to be adapted according to the SNR and the desired degree of de-noising. We develop a method to derive a suitable value for the kernel variance from a noise estimate to adapt pre-image iterations to arbitrary SNRs. In experiments, we compare the performance of kernel PCA and pre-image iterations in terms of objective speech quality measures and automatic speech recognition. The speech data is corrupted by white and colored noise at 0, 5, 10, and 15 dB SNR. As a benchmark, we provide results of the generalized subspace method, of spectral subtraction, and of the minimum mean-square error log-spectral amplitude estimator. In terms of the scores of the PEASS (Perceptual Evaluation Methods for Audio Source Separation) toolbox, the proposed methods achieve a similar performance as the reference methods. The speech recognition experiments show that the utterances processed by pre-image iterations achieve a consistently better word recognition accuracy than the unprocessed noisy utterances and than the utterances processed by the generalized subspace method.

    2014-01-01

    We calculate the pre-main-sequence HZ for stars of spectral classes F to M. The spatial distribution of liquid water and its change during the pre-main-sequence phase of protoplanetary systems is important in understanding how planets become habitable. Such worlds are interesting targets for future missions because the coolest stars could provide habitable conditions for up to 2.5 billion years post-accretion. Moreover, for a given star type, planetary systems are more easily resolved because of higher pre-main-sequence stellar luminosities, resulting in larger planet to star separation for cool stars than is the case for the traditional main-sequence (MS) habitable zone (HZ). We use 1D radiative-convective climate and stellar evolutionary models to calculate pre-main-sequence HZ distances for F1 to M8 stellar types. We also show that accreting planets that are later located in the traditional MS HZ orbiting stars cooler than a K5 (including the full range of M-stars) receive stellar fluxes that exceed the ru...

    2015-11-01

    Full Text Available BACKGROUND Pre-Eclampsia and Eclampsia are the leading causes of maternal and perinatal morbidity and mortality worldwide. In developed countries, much lower incidences have been achieved through aggressive screening and management of Pre-Eclampsia. In developing countries like India, there is a wide gap in quality of health care in cities and rural area. The present study was done to evaluate the incidence of hypertensive disorders and maternal and fetal outcome in a tertiary care centre catering to poor people of Bihar, Bengal and neighboring country, Nepal. MATERIALS AND METHODS This is an observational descriptive study. After obtaining institutional ethical committee approval and informed consent from patients, all the patients presenting to our institution for delivery with Pre-Eclampsia and Eclampsia were included in the study. Socio-economic status, frequency of ANC, age, parity and period of gestation were recorded. Investigations included complete blood count, urinary protein, coagulation profile, liver function tests and kidney function tests. Mode of conduct of delivery and maternal and fetal outcome were thoroughly recorded and described. Data was presented in the form of n (%. RESULTS 64.28% cases with Pre-Eclampsia and 95.12% cases with Eclampsia were from low socio-economic status. 95.12% cases with Eclampsia and 67.5% cases with Pre-Eclampsia had no ANC throughout the pregnancy. Most of the patients were in the age group of 20-25 years. 86.11% cases with Eclampsia and 66.68% with Pre-Eclampsia were primigravida. Most of the patients presented with 37 weeks of gestation. 54.76% Pre-Eclampsia cases and 58.94% Eclampsia delivered by L.S.C.S. Pulmonary edema and acute renal failure were the most common complications. Maternal mortality was 25.60% in Eclampsia cases. The most common cause of maternal mortality was pulmonary edema. Incidence of IUD+ stillbirth was 16.66% in Pre-Eclampsia cases and 34.14% in Eclampsia cases. Overall

    Full Text Available Judi A TurnerDepartment of Anesthesiology, David Geffen School of Medicine, University of California, Los Angeles, CA, USAAbstract: Pre-eclampsia is a significant, multifactorial, multiorgan disease affecting 5%–8% of all pregnancies in the US where it is the third leading cause of maternal mortality. Despite improvements in the diagnosis and management of pre-eclampsia, severe complications can occur in both the mother and the fetus, and there is no effective method of prevention. Early detection and identification of pregnant women most at risk of developing the disease have proven challenging, but recent efforts combining biochemical and biophysical markers are promising. Efforts at prevention of pre-eclampsia with aspirin and calcium have had limited success, but research on modifiable risk factors, such as obesity surgery, are encouraging. Obstetric management of severe pre-eclampsia focuses on medical management of blood pressure and prevention of seizures using magnesium sulfate, but the ultimate cure remains delivery of the fetus and placenta. Timing of delivery depends on several factors, including gestational age, fetal lung maturity, and most importantly, disease severity. Anesthetic management includes regional anesthesia with careful evaluation of the patient’s airway, volume status, and coagulation status to reduce morbidity and mortality. The potential complications of general anesthesia, including intracranial hemorrhage, in these patients make regional anesthesia the preferred choice in many cases. Nevertheless, it is important to be aware of the contraindications to neuraxial anesthesia and to prepare always for the possibility of encountering a difficult airway.Keywords: pre-eclampsia, diagnosis, risk factors, complications, management, anesthesia, prevention

  12. Surface pre-treatment for barrier coatings on polyethylene terephthalate

    Polymers have favourable properties such as light weight, flexibility and transparency. Consequently, this makes them suitable for food packaging, organic light-emitting diodes and flexible solar cells. Nonetheless, raw plastics do not possess sufficient barrier functionality against oxygen and water vapour, which is of paramount importance for most applications. A widespread solution is to deposit thin silicon oxide layers using plasma processes. However, silicon oxide layers do not always fulfil the requirements concerning adhesion and barrier performance when deposited on films. Thus, plasma pre-treatment is often necessary. To analyse the influence of a plasma-based pre-treatment on barrier performance, different plasma pre-treatments on three reactor setups were applied to a very smooth polyethylene terephthalate film before depositing a silicon oxide barrier layer. In this paper, the influence of oxygen and argon plasma pre-treatments towards the barrier performance is discussed examining the chemical and topological change of the film. It was observed that a short one-to-ten-second plasma treatment can reduce the oxygen transmission rate by a factor of five. The surface chemistry and the surface topography change significantly for these short treatment times, leading to an increased surface energy. The surface roughness rises slowly due to the development of small spots in the nanometre range. For very long treatment times, surface roughness of the order of the barrier layer's thickness results in a complete loss of barrier properties. During plasma pre-treatment, the trade-off between surface activation and roughening of the surface has to be carefully considered.

    The current research of machine center accuracy in workspace mainly focuses on the poor geometric error subjected to thermal and gravity load while in operation, however, there are little researches focusing on the effect of machine center elastic deformations on workspace volume. Therefore, a method called pre-deformation for assembly performance is presented. This method is technically based on the characteristics of machine tool assembly and collaborative computer-aided engineering (CAE) analysis. The research goal is to enhance assembly performance, including straightness, positioning, and angular errors, to realize the precision of the machine tool design. A vertical machine center is taken as an example to illustrate the proposed method. The concept of travel error is defined to obtain the law of the guide surface. The machine center assembly performance is analyzed under cold condition and thermal balance condition to establish the function of pre-deformation. Then, the guide surface in normal direction is processed with the pre-deformation function, and the machine tool assembly performance is measured using a laser interferometer. The measuring results show that the straightness deviation of the Z component in the Y-direction is 158.9% of the allowable value primarily because of the gravity of the spindle head, and the straightness of the X and Y components is minimal. When the machine tool is processed in pre-deformation, the straightness of the Z axis moving component is reduced to 91.2%. This research proposes a pre-deformation machine center assembly method which has sufficient capacity to improving assembly accuracy of machine centers.

    2015-04-01

    Full Text Available The aim of this study is to determine academic dishonesty behaviors based on the opinions of pre-service elementary and social studies teachers. This study was designed using a student self-report survey questionnaire. The sample of this study consisted of 445 pre-service teachers. The research data was collected using “the academic dishonesty behaviors opinion survey” developed for this research. The research data was analyzed using descriptive statistical techniques and chi-square test. Results indicated 23 items that pre-service teachers agreed on were about academic dishonesty. Of these 10 items were about academic cheating and 13 items were about plagiarism in assignments. The top three academic dishonesty behaviors based on participants opinion were respectively having another person take the test on behalf, stealing exam materials and handing in someone else's essay with his/her name on it. Most pre-service teachers did not accept 4 items as an academic dishonest behavior. These items were using old exam questions in order to prepare an exam, using someone else's notes in order to prepare an exam, to give information to other class students after taking the exam, and taking an exam after receiving information from students who already took the exam. In this study, another important finding was about gender differences; female preservice teachers showed more concern than male pre-service teachers about academic dishonesty behaviors. There were also a few limited significant differences both in grade and class level in all academic dishonesty behaviors.

  16. Pre-cometary ice composition from hot core chemistry.

    Pre-cometary ice located around star-forming regions contains molecules that are pre-biotic compounds or pre-biotic precursors. Molecular line surveys of hot cores provide information on the composition of the ice since it sublimates near these sites. We have combined a hydrostatic hot core model with a complex network of chemical reactions to calculate the time-dependent abundances of molecules, ions, and radicals. The model considers the interaction between the ice and gas phase. It is applied to the Orion hot core where high-mass star formation occurs, and to the solar-mass binary protostar system IRAS 16293-2422. Our calculations show that at the end of the hot core phase both star-forming sites produce the same prebiotic CN-bearing molecules. However, in the Orion hot core these molecules are formed in larger abundances. A comparison of the calculated values with the abundances derived from the observed line data requires a chemically unprocessed molecular cloud as the initial state of hot core evolution. Thus, it appears that these objects are formed at a much younger cloud stage than previously thought. This implies that the ice phase of the young clouds does not contain CN-bearing molecules in large abundances before the hot core has been formed. The pre-biotic molecules synthesized in hot cores cause a chemical enrichment in the gas phase and in the pre-cometary ice. This enrichment is thought to be an important extraterrestrial aspect of the formation of life on Earth and elsewhere.

  17. Pre-exercise stretching does not impact upon running economy.

    2007-11-01

    Pre-exercise stretching has been widely reported to reduce performance in tasks requiring maximal or near-maximal force or torque. The purpose of this study was to compare the effects of 3 different pre-exercise stretching routines on running economy. Seven competitive male middle and long-distance runners (mean +/- SD) age: 32.5 +/- 7.7 years; height: 175.0 +/- 8.8 cm; mass: 67.8 +/- 8.6 kg; V(.-)O2max: 66.8 +/- 7.0 ml x kg(-1) x min(-1)) volunteered to participate in this study. Each participant completed 4 different pre-exercise conditions: (a) a control condition, (b) static stretching, (c) progressive static stretching, and (d) dynamic stretching. Each stretching routine consisted of 2 x 30-second stretches for each of 5 exercises. Dependent variables measured were sit and reach test before and after each pre-exercise routine, running economy (ml x kg(-1) x km(-1)), and steady-state oxygen uptake (ml x kg(-1) x min(-1)), which were measured during the final 3 minutes of a 10-minute run below lactate threshold. All 3 stretching routines resulted in an increase in the range of movement (p = 0.008). There was no change in either running economy (p = 0.915) or steady-state V(.-)O2 (p = 0.943). The lack of change in running economy was most likely because it was assessed after a period of submaximal running, which may have masked any effects from the stretching protocols. Previously reported reductions in performance have been attributed to reduced motor unit activation, presumably IIX. In this study, these motor units were likely not to have been recruited; this may explain the unimpaired performance. This study suggests that pre-exercise stretching has no impact upon running economy or submaximal exercise oxygen cost.

    Fernandes, Ashley K; Borges, Nicole; Rodabaugh, Heather

    2012-05-01

    Medical schools universally accept the idea that bioethics courses are essential components of education, but few studies which measure outcomes (i.e., knowledge or retention) have demonstrated their educational value in the literature. The goal of this study was to examine whether core concepts of a pre-clinical bioethics course were learned and retained. Over the course of 2 years, a pre-test comprising 25 multiple-choice questions was administered to two classes (2008-2010) of first-year medical students prior to the start of a 15-week ethics course, and an identical post-test was administered at the end of the course. A total of 189 students participated. Paired t tests showed a significant difference between pre-test scores and post-test scores. The pre-test average score was 69.8 %, and the post-test average was 82.6 %, an increase of 12.9 % after the ethics course. The pre- and post-test results also suggested a shift in difficulty level of the questions, with students finding identical questions easier after the intervention. Given the increase in post-test scores after the 15-week intervention, the study suggests that core concepts in medical ethics were learned and retained. These results demonstrate that an introductory bioethics course can improve short-term outcomes in knowledge and comprehension, and should provide impetus to educators to demonstrate improved educational outcomes in ethics at higher levels of B.S.

    Untargeted metabolomic studies generate information-rich, high-dimensional, and complex datasets that remain challenging to handle and fully exploit. Despite the remarkable progress in the development of tools and algorithms, the "exhaustive" extraction of information from these metabolomic datasets is still a non-trivial undertaking. A conversation on data mining strategies for a maximal information extraction from metabolomic data is needed. Using a liquid chromatography-mass spectrometry (LC-MS)-based untargeted metabolomic dataset, this study explored the influence of collection parameters in the data pre-processing step, scaling and data transformation on the statistical models generated, and feature selection, thereafter. Data obtained in positive mode generated from a LC-MS-based untargeted metabolomic study (sorghum plants responding dynamically to infection by a fungal pathogen) were used. Raw data were pre-processed with MarkerLynx(TM) software (Waters Corporation, Manchester, UK). Here, two parameters were varied: the intensity threshold (50-100 counts) and the mass tolerance (0.005-0.01 Da). After the pre-processing, the datasets were imported into SIMCA (Umetrics, Umea, Sweden) for more data cleaning and statistical modeling. In addition, different scaling (unit variance, Pareto, etc.) and data transformation (log and power) methods were explored. The results showed that the pre-processing parameters (or algorithms) influence the output dataset with regard to the number of defined features. Furthermore, the study demonstrates that the pre-treatment of data prior to statistical modeling affects the subspace approximation outcome: e.g., the amount of variation in X-data that the model can explain and predict. The pre-processing and pre-treatment steps subsequently influence the number of statistically significant extracted/selected features (variables). Thus, as informed by the results, to maximize the value of untargeted metabolomic data, understanding

This study was carried out in 4 Iraqi South-central governorates using 596 pre-mating and 628 pregnant buffaloes (during the last two months of gestation. Pre-mating buffaloes were divided randomly into 496 concentrate-supplemented buffaloes (Flushing and 100 control ones. Additionally, pregnant buffaloes were also divided into 528 concentrate- supplemented buffaloes (Steaming up and 100 controls. Each buffalo within the flushing and steaming up groups were fed daily on 7 Kg of concentrate diet (13% crude protein and 1.70 Mcal of net energy for 60 days. The control buffaloes were nourished only on low-quality roughages of the area and wheat bran. Higher estrus (+15%, P<0.01, pregnancy (+23.8%, P<0.05 and calving rates (+30.8%, P<0.01 were observed in concentrate-supplemented buffaloes as compared with controls. An obvious increase in (P<0.05 calving rate (+14.7%, daily milk yield (+44.8% and calf birth weight (+25.6% were noted in steaming up buffaloes in comparison with control buffaloes. Results indicated that improvement in feeding schedule of Iraqi buffaloes during pre-mating and late gestation periods enhanced the reproductive performance and increased milk production of subsequent lactation and calf birth weight. These improvements increased owner income ($174=209,000 Iraqi dinar /buffalo from the sale of meat and milk.

    Full Text Available Abstract Background Poisoned patients are often treated in and discharged from pre-hospital health care settings. Studies of poisonings should therefore not only include hospitalized patients. Aims: To describe the acutely poisoned patients treated by ambulance personnel and in an outpatient clinic; compare patients transferred to a higher treatment level with those discharged without transfer; and study the one-week mortality after pre-hospital discharge. Methods A one-year multi-centre study with prospective inclusion of all acutely poisoned patients ≥ 16 years of age treated in ambulances, an outpatient clinic, and hospitals in Oslo. Results A total of 3757 health service contacts from 2997 poisoning episodes were recorded: 1860 were treated in ambulances, of which 15 died and 750 (40% were discharged without transfer; 956 were treated in outpatient clinic, of which 801 (84% were discharged without transfer; and 941 episodes were treated in hospitals. Patients discharged alive after ambulance treatment were mainly poisoned by opiates (70%, were frequently comatose (35%, had respiratory depression (37%, and many received naloxone (49%. The majority of the patients discharged from the outpatient clinic were poisoned by ethanol (55%, fewer were comatose (10%, and they rarely had respiratory depression (4%. Among the hospitalized, pharmaceutical poisonings were most common (58%, 23% were comatose, and 7% had respiratory depression. Male patients comprised 69% of the pre-hospital discharges, but only 46% of the hospitalized patients. Except for one patient, who died of a new heroin overdose two days following discharge from an ambulance, there were no deaths during the first week after the poisonings in the 90% of the pre-hospital discharged patients with known identity. Conclusion More than half of the poisoned patients treated in pre-hospital treatment settings were discharged without transfer to higher levels. These poisonings were more often

    AIM: To express the complete PreS region of HBV in E.coli with good solubility and stability, and to establish an effective method for purification of the recombinant PreS protein.METHODS: The complete PreS region (PreS1 and PreS2) was fused into a series of tags including glutathione Stransferase (GST), dihydrofolate reductase (DHFR), maltose binding protein (MBP), 6x histidine, chitin binding domain (CBD), and thioredoxin, respectively. Expression of recombinant PreS fusion proteins was examined by SDS-PAGE analysis and confirmed by Western blot. Two fusion proteins, thio-PreS, and PreS-CBD, with desirable solubility and stability, were subjected to affinity purification and further characterization. RESULTS: Recombinant PreS fusion proteins could besynthesized with good yields in E.coli However, most of these proteins except for thio-PreS and PreS-CBD were vulnerable to degradation or insoluble as revealed by SDS PAGE and Western blot. Thio-PreS could be purified by affinity chromatography with nickel-chelating sepharose as the matrix. However, some impurities were also copurified. A simple freeze-thaw treatment yielded most of the thio-PreS proteins in solution while the impurities were in the precipitate. Purified thio-PreS protein was capable of inhibiting the binding of HBV virion to a specific monoclonal antibody against an epitope within the PreS1 domain. CONCLUSION: Increased solubility and stability of the complete PreS region synthesized in E.coli can be achievedby fusion with the thioredoxin or the CBD tag. A simple yet highly effective method has been established for the purification of the thio-PreS protein. Purified thio-PreS protein likely assumes a native conformation, which makes it an ideal candidate for studying the structure of the PreS region as well as for screening antivirals.

    To present an interesting cause of pre-auricular swelling. We report the case of a 39-year-old woman who presented to the ENT department as an emergency with swelling in the left pre-auricular region. The patient had recently travelled to Central America, where the botfly is endemic. On examination, there was a raised, indurated area with a central orifice. A botfly larva was suspected. The larva was suffocated with paraffin paste, allowing removal without remnants being retained. Suffocation of botfly larvae is favoured to surgical removal, due to the possibility of larval remnants being retained and acting as a nidus for infection. The increasing frequency of exotic travel means doctors need to be more aware of tropical medicine.

    Services provided by nurse aides (NAs) directly influence quality of care. Consequently, NA training programs are critical in providing the qualified personnel who carry the bulk of the workload in long-term care facilities. Because studies related to NA pre-job training programs and student satisfaction are limited, we examined NA pre-job training programs and student satisfaction in Taiwan. The highest satisfaction levels were with lecturers and clinical applications. The lowest satisfaction levels were with tuition, class size and practice hours. General hospitals and nursing homes were the preferred sites for providing lectures and clinical practice instruction. The results of this study provide government departments and health care professionals data pertinent to designing more effective NA training programs.

    The microstructure and characteristics of pre-sintered strontium ferrite powderwere investigated by X-ray diffraction, scanning electron microscopy and transmission electron microscopy. The present study shows that the pre-sintered strontium ferrite powder is provided with a certain particle size distribution, which results in high-density magnets. The strontium ferrite particle has a laminar hexagonal structure with a size similar to ferrite single domain. Ferric oxidephase due to an incomplete solid phase reaction in the first sintering is discovered, which will deteriorate the magnetic properties of ferrite magnet. In addition, the waste ferrite magnets with needle shape arranging along C axis in good order into the powders are found, which have no negative effects on finished product quality.

    The metastasis of solid tumours is a vastly complex, dynamic and systemic process involving both primary tumour cells as well as a wide array of stromal and vascular cells. The recruitment and activation of host cells by tumours at both the primary and metastatic sites is crucial for successful metastatic dissemination highlighting the systemic nature of disease progression. The appropriation of distant metastatic sites by primary tumours and the generation of so-called pre-metastatic niches have gained much interest in the last decade complementing the century old 'seed and soil' hypothesis. The idea that tumours are capable of pre-defining future sites of metastasis is both exciting and terrifying as we try to understand the dynamic networks associated with solid tumour metastasis. Exactly how a tumour cell can alter the distant metastatic microenvironment is of great importance and will unlock novel strategies for successfully targeting these processes.

    Full Text Available A 70-year-old male presented with direct trauma to his loin with gross hematuria, as an isolated case of blunt renal trauma (BRT due to a traffic accident. A pre-existing renal lesion (PERL was strongly suspected by his past history of gross macroscopic hematuria and monotrauma to the kidney without other associated injuries. Spiral CT scan with contrast and a retrograde pyelogram (RGP confirmed an occult complex renal cyst. The gold standard of CT diagnosis in this situation is stressed. Computed tomography is particularly useful in evaluating traumatic injuries to kidneys with pre-existing abnormalities. The decision on the initial course of conservative management, ureteral retrograde stenting to drain extravasation, and its final outcome are discussed. Radical nephroureterectomy was carried out by a transperitoneal approach with an early vascular control of the renal pedicle. A brief review of recent literature has been undertaken.

  11. Pre-processing in AI based Prediction of QSARs

    2009-01-01

    Machine learning, data mining and artificial intelligence (AI) based methods have been used to determine the relations between chemical structure and biological activity, called quantitative structure activity relationships (QSARs) for the compounds. Pre-processing of the dataset, which includes the mapping from a large number of molecular descriptors in the original high dimensional space to a small number of components in the lower dimensional space while retaining the features of the original data, is the first step in this process. A common practice is to use a mapping method for a dataset without prior analysis. This pre-analysis has been stressed in our work by applying it to two important classes of QSAR prediction problems: drug design (predicting anti-HIV-1 activity) and predictive toxicology (estimating hepatocarcinogenicity of chemicals). We apply one linear and two nonlinear mapping methods on each of the datasets. Based on this analysis, we conclude the nature of the inherent relationships betwee...

    Pre-Mancos gas fields of northwestern Colorado are on the N.-plunging Douglas Creek arch and E.-W.-trending Axial uplift. Most of the fields produce from sandstone in the Lower Cretaceous Dakota Group and the Upper Jurassic Morrison Formation. Gas also is produced from the Frontier, Entrada, Shinarump, and Weber, of Late Cretaceous, Jurassic, Traissic, and Permian ages, respectively. Dakota and Morrison gas accumulations are controlled primarily by stratigraphic variations of the sandstone reservoirs. Most of the gas being sold is from fields on the Douglas Creek arch because of the availability of pipelines. The total volume of gas sold in 1964 was 1,993 million cu ft and cumulative production was 33,789 million cu ft. The Elk Springs-Winter Valley Field is cited as typical of the area's pre-Mancos gas fields.

    Full Text Available Art educators have a unique opportunity to develop and strengthen a crosscurricular foundation in literacy through art education. Enrolled in a content area reading course, pre-service teachers in art education at one, large southeastern university discovered that using language skills as a lens sharpened their observations of student performance in art classes at the elementary and high school levels. The inclusion of brief lessons featuring listening, reading, speaking, or writing strategies revealed unanticipated academic needs, which impacted classroom performance and artistic development. This increased awareness deepened preservice teachers’ understanding of young students as learners and allowed the preservice teachers to adjust their lesson planning and classroom management skills. The pre-service teachers were more confident in their practice as they witnessed the results of their efforts in terms of students’ improved levels of artistic achievements.

    2016-01-01

    Malnutrition is universaly prevalent among pre-liver transplantation patients. Malnutrition among cirrhotic patients had been associated to increased morbidity and mortality rates. Also, severely malnourished patients before the transplant surgery have a higher rate of complications and a decreased overal survival rate after liver transplantation. In light of the high incidence of malnutrition and associated complications, it is essential to initiate treatment as early as it is assessed. This review addresses the aetiologies of malnutrition and appropriate treatment strategies to correct it in pre-liver transplant phase. Treatment should focus on maintaining nutrient intake and correcting various nutritional deifciencies. The dietician plays an integral role as part of the transplant team by providing appropriate nutrition therapy for solving various nutrition problems.

    Over 450 pre-Columbian (pre-AD 1492) geometric ditched enclosures ("geoglyphs") occupy ∼13,000 km(2) of Acre state, Brazil, representing a key discovery of Amazonian archaeology. These huge earthworks were concealed for centuries under terra firme (upland interfluvial) rainforest, directly challenging the "pristine" status of this ecosystem and its perceived vulnerability to human impacts. We reconstruct the environmental context of geoglyph construction and the nature, extent, and legacy of associated human impacts. We show that bamboo forest dominated the region for ≥6,000 y and that only small, temporary clearings were made to build the geoglyphs; however, construction occurred within anthropogenic forest that had been actively managed for millennia. In the absence of widespread deforestation, exploitation of forest products shaped a largely forested landscape that survived intact until the late 20th century.

  20. Pre-heating in the framework of massive gravity

    Directory of Open Access Journals (Sweden)

    Debaprasad Maity

    2016-09-01

    Full Text Available In this paper we propose a mechanism of natural pre-heating of our universe by introducing an inflaton field dependent mass term for the gravitational wave for a specific class of massive gravity theory. For any single field inflationary model, the inflaton must go through the oscillatory phase after the end of inflation. As has recently been pointed out, if the gravitational fluctuation has inflaton dependent mass term, there will be a resonant amplification of the amplitude of the gravitational wave during the oscillatory phase of inflaton. Because of this large enhancement of the amplitude of the gravitational wave due to parametric resonance, we show that universe can naturally go through the pre-reheated phase with minimally coupled matter field. Therefore, during the reheating phase, there is no need to introduce any arbitrary coupling between the matter field and the inflaton.

  1. Pre-formed plasma channels for ion beam fusion

    Peterson, R. R.; Olson, C. L.

    1997-04-01

    The transport of driver ions to the target in an IFE power plant is an important consideration in IFE target chamber design. Pre-formed laser-guided plasma discharge channels have been considered for light ions because they reduce the beam microdivergence constraints, allow long transport lengths, and require a target chamber fill gas that can help protect the target chamber from the target explosion. Here, pre-formed plasma discharge channels are considered for heavy ion transport. The channel formation parameters are similar to those for light ions. The allowable ion power per channel is limited by the onset of plasma instabilities and energy loss due to a reverse emf from the rapid channel expansion driven by the ion beam.

    Laser treatment of pre-prepared zirconia surface is carried out. The pre-prepared surface, prior to laser treatment, consists of 50 {mu}m carbon film and 7% titanium carbide particles, which are imbedded in the carbon film. The microstructural and morphological changes in the laser treated surface layer are examined using optical and scanning electron microscopes, energy dispersive spectroscopy, and X-ray diffraction. The fracture toughness of the laser treated surface is measured and the residual stress formed at the surface vicinity is determined from the X-ray diffraction technique. It is found that the microhardness of the laser treated surface increased slightly due to the dense layer formed at the surface vicinity. However, the laser treatment process reduces the fracture toughness of the surface due to improved surface hardness and the residual stress formed in the surface vicinity.

    The traditional communication infrastructure of the pre-hospital Emergency Medical System (EMS) is limited to voice communication using radio or cell phone technologies. With the emergence of 3rd Generation wireless networks (3G) and enhanced mobile devices capable of data communication (e.g., mobile tablets, PDAs with cell phones, or cell phones with PDA capabilities), the voice communication can be enhanced with interactive data messaging and perhaps even with interactive video communication. However, video requires substantially more bandwidth which 4th Generation (4G) systems are promising. However, their availability is limited. We present an infrastructure that allows dynamic selection of the best data transport mode in the pre-hospital EMS environment.

  4. How Much of the Unconscious Is Just Pre - Threshold?

    Directory of Open Access Journals (Sweden)

    Manfred Wilhem Fahle

    2011-10-01

    Full Text Available Visual awareness is a specific form of consciousness. Binocular rivalry, the alternation of visual consciousness resulting when the two eyes view differing stimuli, allows one to experimentally investigate visual awareness. Observers usually indicate the gradual changes of conscious perception in binocular rivalry by a binary measure: pressing a button. However, in our experiments, gradual measures such as pupil and joystick movements start around 590 ms before observers press a button, apparently accessing even pre-conscious processes. Our gradual measures permit monitoring the built-up, over time, of decision processes and that should not be considered as abrupt events. Changes in analogue measures occurring before button presses signalling decisions do not prove these decisions are taken subconsciously – eliminating free will - but just prepared pre-thresholdly.

    Individuals frequently experience mental fatigue during or after prolonged periods of cognitive activity. We investigated the effects of mental fatigue on the ability to detect minor changes in the pre-attentive stage of information processing by recoding MMN of ERP components. The equal probable paradigm was employed to elicit pure memory-comparison-based MMN component. Mental fatigue was induced by the continuous performance for 2h of mental arithmetic tasks. MMN amplitudes at fronto-central electrode sites were significantly decreased in subjects with mental fatigue than in subjects under control conditions, whereas temporal MMN was not affected by mental fatigue. These results suggest that mental fatigue impairs pre-attentive processing.

    Full Text Available This work focuses on technological and educational outcomes that resulted from the production of foreign language educational videos by 90 pre-service instructors enrolled in an official Master’s Degree in Secondary Education programme. This teaching practice, conducted during two consecutive years, was set in a ubiquitous learning environment with the intention of effectively linking digital technology with pedagogy by means of producing flipped classroom units. The findings reveal that these pre-service teachers successfully combined instructional dynamics with digital skills to produce flipped classes adapted to the young generation’s needs. The classroom becomes, therefore, a more participatory learner-centred scenario with a variety of interactive and collaborative activities performed by foreign language students.

    The localization of SeqA, thymidylate synthase, DnaB (helicase) and the DNA polymerase components alpha and tau, has been studied by immunofluorescence microscopy. The origin has been labelled through GFP-LacI bound near oriC. SeqA was located in the cell centre for one replication factory (RF) and at 1/4 and 3/4 positions in pre-divisional cells harbouring two RFs. The transition of central to 1/4 and 3/4 positions of SeqA appeared abrupt. Labelled thymidylate synthetase was found all over the cell, thus not supporting the notion of a dNTP-synthesizing complex exclusively localized near the RF. More DnaB, alpha and tau foci were found than expected. We have hypothesized that extra foci arise at pre-replication assembly sites, where the number of sites equals the number of origins, i.e. the number of future RFs. A reasonable agreement was found between predicted and found foci. In the case of multifork replication the number of foci appeared consistent with the assumption that three RFs are grouped into a higher-order structure. The RF is probably separate from the foci containing SeqA and the hemi-methylated SeqA binding sites because these foci did not coincide significantly with DnaB as marker of the RF. Co-labelling of DnaB and oriC revealed limited colocalization, indicating that DnaB did not yet become associated with oriC at a pre-replication assembly site. DnaB and tau co-labelled in the cell centre, though not at presumed pre-replication assembly sites. By contrast, alpha and tau co-labelled consistently suggesting that they are already associated before replication starts.

    The escalation of alcohol use among some Latino immigrant groups as their time in the United States increases has been well documented. Yet, little is known about the alcohol use behaviors of Latino immigrants before immigration. This prospective longitudinal study examines pre- to postimmigration alcohol use trajectories among a cohort of recent Latino immigrants. Retrospective preimmigration data were collected at baseline from a sample of 455 Cuban, South American, and Central American Latinos ages 18-34 who immigrated to the United States less than 1 year prior. Two follow-up assessments (12 months apart) reported on their postimmigration alcohol use in the past 90 days. We hypothesized (a) overall declines in pre- to postimmigration alcohol among recent Latino immigrants and (b) gender/documentation specific effects, with higher rates of alcohol use among males and undocumented participants compared to their female and documented counterparts. Growth curve analyses revealed males had higher levels of preimmigration alcohol use with steeper declines in postimmigration alcohol use compared to females. Declines in alcohol use frequency were observed for documented, but not undocumented males. No changes in pre- to postimmigration alcohol use were found for documented or undocumented females. This study contributes to the limited knowledge of pre- to postimmigration alcohol use patterns among Latinos in the United States. Future research is needed to identify social determinants associated with the alcohol use trajectories of recent Latino immigrants, as it may inform prediction, prevention, and treatment of problem-drinking behaviors among the largest and fastest growing ethnic minority in the United States.

    An Einstein nilradical is a nilpotent Lie algebra, which can be the nilradical of a metric Einstein solvable Lie algebra. The classification of Riemannian Einstein solvmanifolds (possibly, of all noncompact homogeneous Einstein spaces) can be reduced to determining, which nilpotent Lie algebras are Einstein nilradicals and to finding, for every Einstein nilradical, its Einstein metric solvable extension. For every nilpotent Lie algebra, we construct an (essentially unique) derivation, the pre...

    The partial reflection method of determining electron densities and collision frequencies in the ionospheric D region, is briefly described. Possible applications of the observations to the study of turbulent fine structure in the propagation medium are mentioned. The PRE (Partial Reflection Experiment) facility at the University of Tromsoe's field site at Ramfjordmoen is described. The use of the facility in relation to and coordinated with other experiments (including rockets), is discussed.

    Urinary bladder is a known content of sliding inguinal hernias but rarely presents as irreducible direct inguinal hernia. As inguinal hernia repair is commonly undertaken even at peripheral surgical centers. Cystogram a simple radiological investigation (picturesque view) is useful for pre-surgical evaluation as it can prevent iatrogenic bladder injury during inguinal hernia repair. This investigation can be performed where other radiological expertises like computerized tomography scan/magne...

Cystogram a simple radiological investigation (picturesque view) is useful for pre-surgical evaluation as it can prevent iatrogenic bladder injury during inguinal hernia repair. This investigation can be performed where other radiological expertises like computerized tomography scan/magnetic resonance imaging or even ultrasound facilities are not readily available.
