The Laryngeal Mask Airway Supreme™: safety and efficacy during gynaecological laparoscopic surgery

Abstract Background: Laryngeal Mask Airway Supreme™ (LMA Supreme™) is a new single-use polyvinyl chloride supraglottic device that offers gastric access. To date, studies that have tested the LMA Supreme™) for use in laparoscopic surgery have been reported. We present the largest evaluative study that describes the use of this mask for anaesthesia in gynaecological laparoscopic surgery. Method: Hospital ethics board approval was obtained, and 140 fasted patients undergoing elective gynaecological laparoscopy were prospectively studied. We evaluated the ease of insertion of the device and the drain tube, the oropharyngeal leak pressure (OLP), incidence of postoperative sore throat, and other adverse events. Results: Insertion of the LMA Supreme™ was successful in all patients (first attempt, n = 123; second attempt, n = 16; and third attempt, n = 1). Gastric tube insertion was successful in all patients (easy, n = 135; difficult, n = 5). Initial mechanical ventilation was adequate in almost all cases. Mean OLP at the level of 60 cmH2O cuff pressure was 28.2 ± 5.1 cmH2O. Mean peak airway pressure before pneumoperitoneum was 17± 3.5 cmH2O, and 22.1 ± 4 cmH2O, after pneumoperitoneum. Fourteen patients (10%) complained of a mild sore throat postoperatively. Coughing occurred in 10 patients (7.1%), and blood was noted after removal of the LMA Supreme™ in five cases (3.5%). No other complications were reported. Conclusion: We conclude that LMA Supreme™ is an easy to insert, and effective ventilatory device, for gynaecological laparoscopic surgery. It provides a functional airway seal with minimum adverse events.
A Low-Voltage Ride-Through Control Strategy for Two-Stage T-Type Three-Level Photovoltaic Inverters Limiting DC-Link Overvoltage and Grid-Side Overcurrent

To ensure the stable operation of grid-connected photovoltaic (PV) generation systems when grid voltage dips, the grid-connected inverters are required to have the low-voltage ride-through (LVRT) capability. Based on a two-stage grid-connected inverter which consists of a boost converter and a T-type three-level inverter, the effects of symmetric and asymmetric grid voltage dips on the PV grid-connected system with conventional control strategy is analyzed, and the conclusion that the main incentives of LVRT failure are dc-link overvoltage and grid-side overcurrent is drawn. In this paper, an improved control strategy to avoid LVRT failure for the two-stage grid-connected inverter is proposed. For grid synchronization under grid voltage dip, a dual second-order generalized integrator (DSOGI) pre-filtered based phase-locked loop is adopted. According to PV voltage control scheme during LVRT, a modified PV voltage reference generation method is interpreted, which can make the PV panels work at the point where the power balance is automatically achieved, and thus the dc-link overvoltage is limited. Then a full feedforward of point of common coupling (PCC) voltage is introduced, which can not only limit the overshoot of the grid-side current, but also eliminate its negative-sequence component under an asymmetric voltage dip. By using the proposed control strategies, the LVRT failure can be successfully avoided and the LVRT requirements can be met. The simulation results verify the effectiveness of these control strategies.
PROGRAMMING ONE ’ S OWN STAND-ALONE TEACHING AIDS FOR STUDENTS OF MATHEMATICAL SUBJECTS

The article encourages teachers to program their own applications – mathematical teaching aids. It discusses the issue of teaching aids for students in mathematical subjects from the point of view of their accessibility, i.e. especially what software equipment students are required to use in order to actually use the aids. A number of aids require that either specialized mathematical software such as Maple, Matlab or Mathematica is installed at the client computer – i.e. that the student bought a license of the software, or that specialized software is installed at the university server(s). The article focuses on situations when neither of the conditions is possible. Comments on programming teaching aids which can be used with minimum requirements at the client side (typically Internet connection only) are included. First, the overview of possibilities is given. Later, the issue of PHP based applications is explored. The article includes examples of existing teaching aids prepared by a non-programmer.
A Psychometric Validation Analysis of Eysencks Neuroticism and Extraversion Scales in a Sample of First Time Depressed Patients

Eysenck and Eysenck identified the two-factor structure of personality, namely neuroticism and extraversion which has been widely used in clinical psychiatry, and generated much research on the psychometric properties of the scales. Using a classical psychometric approach the neuroticism and extraversion scales have shown robust psychometric properties. The present study used both classical psychometric and item response theory (IRT) analyses to evaluate the neuroticism and extraversion scales and improve scalability of the instrument. A first time depressed sample completed the Eysenck Personality Questionnaire (EPQ) and Hamilton Depression Rating Scale (Ham-D 17-item) at baseline and at follow-up five years later. For the neuroticism scale a subscale containing depression-related symptoms, a subscale containing anxietyrelated symptoms, and a subscale containing symptoms related to interpersonal sensitivity were identified. For the extraversion scale a shorter and psychometrically more robust version was identified together with a short introversion scale. Clinically discriminant validity was analysed using correlations. The correlation between depression (Ham-D-17) and neuroticism-anxiety was below clinical significance, while the correlation of depression (Ham-D-17) was above clinical significance for both interpersonal sensitivity and neuroticism-depression. Clinically discriminant validity was modest for the extraversion/ introversion subscales however the introversion subscale approached clinical significant correlation with depression. The identified subscales of the EPQ, neuroticism-anxiety, interpersonal sensitivity, neuroticism-depression, extraversion and introversion are psychometrically valid measures of type and severity of the stress response. Using these subscales, it is possible to perform a quick and psychometrically valid evaluation of the type and severity of the stress response. The subscales may be useful in predicting types of psychopathology and in identifying underlying vulnerability that could serve as specific treatment targets in preventing as well as treating depression and anxiety
THE INFLUENCE OF SODIUM FLUORIDE IN ALLOPATHIC AND HOMEOPATHIC DOSES ON CENTRAL NERVOUS SYSTEM ’ S PERFORMANCES . A CORRELATION BETWEEN BEHAVIORAL RESPONSE IN CLASSIC MAZE TEST AND MORPHOLOGICAL ASPECTS OF CEREBRAL CORTEX

The influence of fluorine administration on central nervous system’s (CNS) performances in female mice treated during gestation with two distinct doses of sodium fluoride (NaF): 0.25 mg and 0.50 mg. The research extended also to offspring (generation 1 – F1), treated with NaF in allopathic (0.25 and 0.50 mg), homeopathic (7CH) or with the association between the two types (allopathic and homeopathic) of doses. CNS performance modification was also assessed in the second generation offspring (F2), in which fluorine was exclusively taken from ascendant generations. Evaluation of CNS activity was performed by determining clearing time in classic maze (CM) at several time intervals (roughly 21 days between determinations). Experimental results showed that, in young offspring (1 – F1) from ascendants treated with the same substance, CNS performances in investigative capacity are influenced depending on dose, gender and age. Similar effect was recorded for homeopathic remedy 7CH for which the influence on CNS performance is strongly correlated to the stage of physical development of offspring and to doses of NaF administered to ascendants. The results of pharmacological tests correlate strongly to modifications noted during anatomical pathology examination of cerebral cortex.
INVESTIGATION OF TOTAL DIETARY FIBER, B1 AND B2 VITAMIN CONTENT OF FLOUR BLEND FOR PASTA PRODUCTION

The main purpose of the current research was to investigate total dietary fiber and vitamin B1 and B2 content in flour blends made from several types’ whole grain flour for pasta production. In 2012 harvested convectional rye ‘Kaupo’, wheat ‘Zentos’, hull -less barley line ‘PR 5099‘ and triticale line ‘9405 -23‘ grain and, for flour blends obt aining, wheat flour type 550 was used in the experiments. Following quality parameters of flours using standard methods was evaluated: total dietary fiber content (ISO 5498) and vitamins B1 and B2 – by AOAC 986.27 and 970.65 respectively. In the present research significant differences in total dietary fiber of analysed whole grain rye, hull-less barley, triticale and wheat flour samples were established. Higher dietary fiber content was found in whole grain hull-less barley and rye flour, the lowest in the wheat flour type 550. Lower dietary fiber content was obtained for whole wheat and triticale flour blends. However, the higher, for whole rye and hull-less barley flour blend. B1 vitamin content in whole grain rye and wheat flour was significantly higher than in hull-less barley and triticale. Lowest vitamin B2 content was obtained in wheat flour type 550. Lower B1 vitamin content, as 2.70±0.14 mg kg -1 was obtained for whole hull-less barley flour blend, the higher as 3.19±0.28 mg kg -1 for whole wheat flour blend. Lower B2 vitamin content, as 0.91±0.06 mg kg -1 , was obtained for whole hull-less barley flour blend, however, the higher B2, as 0.81±0.28 mg kg -1 in whole wheat flour blend.
Classifier Ensembles for Detecting Concept Change in Streaming Data: Overview and Perspectives

We address adaptive classification of streaming data in the presence of concept change. An overview of the machine learning approaches reveals a deficit of methods for explicit change detection. Typically, classifier ensembles designed for changing environments do not have a bespoke change detector. Here we take a systematic look at the types of changes in streaming data and at the current approaches and techniques in online classification. Classifier ensembles for change detection are discussed. An example is carried through to illustrate individual and ensemble change detectors for both unlabelled and labelled data. While this paper does not offer ready-made solutions, it outlines possibilities for novel approaches to classification of streaming data.
Complementary Strategies for Low Resourced Morphological Modeling

Morphologically rich languages are challenging for natural language processing tasks due to data sparsity. This can be addressed either by introducing out-of-context morphological knowledge, or by developing machine learning architectures that specifically target data sparsity and/or morphological information. We find these approaches to complement each other in a morphological paradigm modeling task in Modern Standard Arabic, which, in addition to being morphologically complex, features ubiquitous ambiguity, exacerbating sparsity with noise. Given a small number of out-of-context rules describing closed class morphology, we combine them with word embeddings leveraging subword strings and noise reduction techniques. The combination outperforms both approaches individually by about 20% absolute. While morphological resources already exist for Modern Standard Arabic, our results inform how comparable resources might be constructed for non-standard dialects or any morphologically rich, low resourced language, given scarcity of time and funding.
Collagen: levels of structure and alignment

Collagen structure and function Collagen is the most abundant protein in the human body, accounting for around 30% of the total amount of protein. Collagen is a structural support for most tissues in the body as the extracellular matrix, and is particularly abundant in connective tissue. Skin, for example, is around 75% collagen, and collagen therefore has a vital role in many processes such as wound healing. Collagen production or mineralisation are the basis for the formation of cartilage, tendons or bones. Cells in all the other tissues of the body are also surrounded by finer collagen structures through the extracellular matrix, so collagen has a vital role also in cell proliferation, migration and differentiation.

Particle swarm optimization for multimachine power system stabilizer design

In this paper, a novel evolutionary algorithm based approach to optimal design of multimachine power system stabilizers (PSSs) is proposed. The proposed approach develops and employs particle swarm optimization (PSO) technique to search for optimal settings of PSS parameters. Two eigenvalue-based objective functions to enhance system damping of electromechanical modes are considered. The robustness of the proposed approach to the initial guess is demonstrated. The performance of the proposed PSO based PSS (PSOPSS) under different disturbances and loading conditions is tested and examined. Eigenvalue analysis and nonlinear simulation results show the effectiveness of the proposed PSOPSSs to damp out the electromechanical oscillations and work effectively over a wide range of loading conditions.
Improved parameters for the transiting hot Jupiters WASP-4b and WASP-5b

The gaseous giant planets WASP-4b and WASP-5b are transiting 12-magnitude solar-type stars in the Southern hemisphere. The aim of the present work is to refine the parameters of these systems using high cadence VLT/FORS2 z-band transit photometry and highresolution VLT/UVES spectroscopy. For WASP-4, the new estimates for the planet radius and mass from a combined analysis of our VLT data with previously published transit photometry and radial velocities are Rp = 1.30 +0.05 −0.04 RJ and Mp = 1.21 +0.13 −0.08 MJ, resulting in a density ρp = 0.55 +0.04 −0.02 ρJ. The radius and mass for the host star are R∗ = 0.87 +0.04
NEWSPAPERS, FACEBOOK AND TWITTER Intermedial agenda setting in local election campaigns

Social media, such as Facebook, Twitter, YouTube and many other services, have established themselves as part of the networked and increasingly hybrid public sphere, extending and transforming it to allow for and facilitate access to all kinds of content and participants. By their sheer ubiquity, these media contribute to changing media ecologies and open new ways and forms of communications between citizens and their representatives. During election campaigns, political parties and their candidates have a number of ways of seeking to mobilise voters by attracting attention to the parties’ issues and top candidates. Many of these involve processes of mediatisation, that is, parties and politicians adapt their practices and messages to formats, deadlines and genres that are journalistically attractive. This study seeks to map and understand intermedial agenda setting between social media and traditional news media by analysing data from both local journalism and the social media activity of local politicians during the 2011 Norwegian local election campaigns. Our findings show that local politicians were active on social media as part of their campaigning, yet there was surprisingly little evidence that social media content travelled to local newspapers and contributed to agenda setting, thereby contradicting findings from other settings stating that social media have become established journalistic sources. We suggest that one explanation may lay in the nature of Norwegian politics and culture in which the distance between journalists, citizens and politicians is notably small.

Skeletal Neoplasms

Among the acquired disorders of cartilage and bone are a variety of neoplasms. Some are malignant and cause considerable morbidity and can metastasize and kill. Others are benign and may even heal spontaneously. Rarely, skeletal tumors behave as though “transitional,” with both malignant and benign features. Diagnosis and treatment of bone tumors is a complex and specialized discipline. Only a brief overview is provided here. Additional resources include several comprehensive texts devoted to this topic. (1–7) Classification of skeletal neoplasms begins with the apparent cell or tissue type of origin (Table 1). The source of the tumor is usually revealed by the kind of tissue that the neoplastic cells make, such as osteoid or cartilage. However, in a few instances (e.g., giant cell tumor of bone), the origin is less clear. (1,5) Chromosomal defects are detected more often in malignant than in benign skeletal neoplasms. (8) Biological behavior of bone tumors importantly influences their classification. Within the two major categories, benign and malignant, there are different degrees of aggressiveness. Biological behavior reflects the capacity of the tumor to exceed its natural barriers. Such barriers may include a tumor capsule (the shell of fibrous tissue or bone around the neoplasm), a reactive zone (composed in part of fibrous tissue or bone that forms between the capsule and normal tissue), and any adjacent articular cartilage, cortical bone, or periosteum. (1,5,7) Skeletal neoplasms will be properly managed only when there is a thorough understanding of their clinical presentation and natural history, as well as use of current staging procedures. (9) This often requires histopathological examination. (1,5,9) Proper choice of therapy may include medical and/or surgical approaches. (1–3,5,7,10–12) Optimum patient management can depend on multidisciplinary expertise. (1–7) Improved radiological imaging,(13,14) histopathological methods, cytogenetic and molecular testing, surgical techniques, and chemotherapeutic regimens have all contributed to better survival and function of patients with skeletal sarcomas. Chemotherapy has improved the treatment of early metastatic deposits. (12–18) Consequently, aggressive limb-salvaging procedures are now possible with survival rates that were previously achieved only by radical amputation. (16,19–22)
A GPU-Based Algorithm for the Generation of Spherical Voronoi Diagram in QTM mode

The spherical Voronoi diagram is a type of the global data model in Digital Earth which has become increasingly important and a lot of efforts have been done to develop the algorithms. However, most of the prior works were in vector mode and based on point sets. Recently, some approximation raster-based algorithms were presented which can generate spherical Voronoi diagrams for point, curve, and face sets easily. However, almost all these raster-based algorithms are based on dilation operation and the dilation errors increase greatly with the growth of dilation steps. To overcome this deficiency, a novel GSG-based algorithm for generating spherical Voronoi diagram is proposed in this paper. In our algorithm, distance computation and comparison based on GPU are used instead of dilation operation to diminish the Voronoi error and improve the efficiency. Results show that line sets and area sets can be handled as well as point sets in this algorithm and the Voronoi error can be limited within half of one grid. Additionally, the efficiency for generating spherical Voronoi diagram is improved greatly.
Convergence of configuration-interaction single-center calculations of positron-atom interactions

The configuration interaction (CI) method using orbitals centered on the nucleus has recently been applied to calculate the interactions of positrons interacting with atoms. Computational investigations of the convergence properties of binding energy, phase shift, and annihilation rate with respect to the maximum angular momentum of the orbital basis for the e{sup +}Cu and PsH bound states, and the e{sup +}-H scattering system were completed. The annihilation rates converge very slowly with angular momentum, and moreover the convergence with radial basis dimension appears to be slower for high angular momentum. A number of methods of completing the partial wave sum are compared; an approach based on a {delta}X{sub J}=a(J+(1/2)){sup -n}+b(J+(1/2)){sup -(n+1)} form [with n=4 for phase shift (or energy) and n=2 for the annihilation rate] seems to be preferred on considerations of utility and underlying physical justification.
Land Accumulation Dynamics in Developing Country Agriculture

Abstract Understanding land accumulation dynamics is relevant for policy-makers interested in the economic effects of land inequality in developing country agriculture. We thus explore and simultaneously test the leading theories of micro-level land accumulation dynamics using unique panel data from Paraguay. The results suggest that farm growth varies systematically with farm size – a formal rejection of stochastic growth theories (that is, Gibrat’s Law) – and that titled land area may have considerable influence on land accumulation. Furthermore, our estimates indicate that a dualistic agrarian structure is the likely product of the unfettered operation of land markets.
Environmental responses of the Northeast Antarctic Peninsula to the Holocene climate variability

In this study, we present a unique high-resolution Holocene record of oceanographic and climatic change based on analyses of diatom assemblages combined with biomarker data from a sediment core collected from the Vega Drift, eastern Antarctic Peninsula (EAP). These data add to the climate framework already established by high-resolution marine sedimentary records from the Palmer Deep, western Antarctic Peninsula (WAP). Heavy sea ice conditions and reduced primary productivity were observed prior to 7.4 ka B.P. in relation with the proximity of the glacial ice melt and calving. Subsequent Holocene oceanographic conditions were controlled by the interactions between the Westerlies-Antarctic Circumpolar Current (ACC)-Weddell Gyre dynamics. A warm period characterized by short seasonal sea ice duration associated with a southern shift of both ACC and Westerlies field persisted until 5 ka B.P. This warm episode was then followed by climate deterioration during the middle-to-late Holocene (5 to 1.9 ka B.P.) with a gradual increase in annual sea ice duration triggered by the expansion of the Weddell Gyre and a strong oceanic connection from the EAP to the WAP. Increase of benthic diatom species during this period was indicative of more summer/autumn storms, which was consistent with changes in synoptic atmospheric circulation and the establishment of low- to high-latitude teleconnections. Finally, the multicentennial scale variability of the Weddell Gyre intensity and storm frequency during the late Holocene appeared to be associated with the increased El Nino–Southern Oscillation frequency.
