POSITRON PRODUCTION BY GAMMA BEAM AT ELI–NP

We propose to obtain an intense beam of moderated positrons (es) with an intensity of the primary positron beam of 1×106 2×106 ess by the (γ, e+e−) reaction using an intense γ-beam of 2.4×1010 γ s−1 with energies up to 3.5 MeV. Using fully circularly polarized γ-beam we aim to obtain an intense, polarized positron beam with a polarization degree of 31-45%. Higher degree of polarization would also be possible with reduced beam intensity. The beam will be transported to different detector systems through beam lines, via solenoidal magnetic fields. Polarized positron beams open up a totally unexplored research area in applied physics studies of Fermi-surfaces, defects, interfaces etc., where polarized electrons can be studied. A simple, fast scintillator detector system for γ-induced positron annihilation lifetime spectroscopy for studies of bulk samples is proposed. The ELI-NP facility will be user-dedicated and unique for positron research in the Eastern Europe. It will provide a simple source setup, with easy access for upgrades of the converter/moderator assembly toward more sophisticated setups, providing a more intense and brighter positron beam. The beam will have the world highest intensity of polarized positrons for material science studies and, therefore, it will become a unique tool for the investigation of magnetic samples.
Efficient synthesis of some new antiproliferative N-fused indoles and isoquinolines via 1,3-dipolar cycloaddition reaction in an ionic liquid

Syntheses of some new pyrrolo-fused pyrrolo[1,2-a] indole derivatives have been achieved by combining N-allyl-indole-2-carbaldehyde with a variety of N-alkyl-glycine esters as well as tetrahydroisoquinolines in an ionic liquid, triethylammonium acetate (TEAA), a recyclable reaction medium, via intramolecular [3+2] cycloaddition reaction. This new method is highly efficient, and the ionic liquid employed is recyclable. The stereochemistry of all the compounds was confirmed by 2D NMR NOESY and in some cases single crystal X-ray diffraction data. The in vitro screening of all new candidates against various bacterial strains and representative human solid tumor cell lines, A549 (lung), HeLa (cervix), SW1573 (lung), T-47D (breast) and WiDr (colon), revealed that many of them have good antibacterial, antifungal and antitubercular and antiproliferative activities.
Does the stellar disc flattening depend on the galaxy type

We analyse the dependence of the stellar disc flatness on the galaxy morphological type using 2D decomposition of galaxies from the reliable subsample of the Edge-on Galaxies in SDSS catalogue. Combining these data with the retrieved models of the edge-on galaxies from the Two Micron All Sky Survey and the Spitzer Survey of Stellar Structure in Galaxies catalogue, we make the following conclusions. (1) The disc relative thickness z0/h in the near- and mid-infrared passbands correlates weakly with morphological type and does not correlate with the bulge-to-total luminosity ratio B/T in all studied bands. (2) Applying a 1D photometric profile analysis overestimates the disc thickness in galaxies with large bulges making an illusion of the relationship between the disc flattening and the
Effects of Organic Fertilizer on Hepatic Lipid Levels and Cholinesterase Activity in Channa punctatus ( Bloch )

The effects of mustard oil cake (MOC) on liver lipid levels and brain cholinesterase activity of Channa punctatus (Bloch) were assessed. Due to excessive use, these organic fertilizers enter the freshwater ecosystem as runoff during irrigation and heavy rain, reaching concentrations higher than those required in the rearing pond. Fish were exposed to 0.42 mgl-1 MOC for 35 days. The results reveal that liver lipid levels were higher during exposure in both control and treated fish when compared to 0 day levels. Lipid levels decreased slightly after 21 (in both treated and untreated fish) and 35 days (in untreated fish). Results also showed an increase in brain cholinesterase activity in MOC-exposed fish.
AN EXHAUSTIVE ANALYSIS OF AUTOMATIC GENRE CLASSIFICATION

The increase of the musical databases on the Internet and multimedia systems have brought a great demand for music information retrieval (MIR) applications, and especially automatic analysis of musical databases. A classifier system that allows to make a genre classification, considering a symbolic database into hierarchically organized taxonomies is developed in this work. It is also described the process of applying supervised Machine Learning (ML) to music genre classification. The classification system begins with the feature extraction from the Musical Instrumental Digital Interface (MIDI) files, in which it was applied then a feature selection algorithm, known by Sequential Floating Forward Selection Least Squares. Finally, the classifiers used in the classification system were Support Vector Machines (SVM) and KNearest Neighbour (KNN). A similarity metric known by Normal Compression Distance (NCD) and based on Kolmogorov Distance was also tested. NCD was used in the KNN classifier, in which new approaches were realized, mainly in the discretization procedure, and in the convertion of the feature values into a string. As the results obtained with NCD, by considering the KNN classifier, were higher than the results obtained with the Euclidean distance, it was decided to use the NCD in the KNN considered in the classifier system. The classifier ensemble proved to be an interesting approach, achieving results that can be compared to the best music genre classification methods reported in the literature.

Block bootstrap panel unit root tests with deterministic terms

This thesis is comprised of five papers that all relate to bootstrap methodology in analysis of non-stationary time series.The first paper starts with the fact that the Dickey-Fuller unit root test using asymptotic critical value has bad small sample performance. The small sample correction proposed by Johansen (2004) and bootstrap are two effective methods to improve the performance of the test. In this paper we compare these two methods as well as analyse the effect of bias-adjusting through a simulation study. We consider AR(1) and AR(2) models and both size and power properties are investigated.The second paper studies the asymptotic refinement of the bootstrap cointegration rank test. We expand the test statistic of a simplified VECM model and a Monte Carlo simulation was carried out to verify that the bootstrap test gives asymptotic refinement.The third paper focuses on the number of bootstrap replicates in bootstrap Dickey-Fuller unit root test. Through a simulation study, we find that a small number of bootstrap replicates are sufficient for a precise size, but, with too small number of replicates, we will lose power when the null hypothesis is not true.The fourth and last paper of the thesis concerns unit root test in panel setting focusing on the test proposed by Palm, Smeekes and Urbain (2011). In the fourth paper, we study the robustness of the PSU test with comparison with two representative tests from the second generation panel unit root tests. In the last paper, we generalise the PSU test to the model with deterministic terms. Two different methods are proposed to deal with the deterministic terms, and the asymptotic validity of the bootstrap procedure is theoretically checked. The small sample properties are studied by simulations and the paper is concluded by an empirical example.

Framing Windowing | DFT ( · ) | Spectral Similarity Note Components Refinement Onset Detection Resynthesize Single Notes Onset Detection

In this paper we propose a new analysis-by-synthesis algorithm for multipitch tracking. It uses spectral base components extracted from isolated piano notes to model a spectrum. The advantage compared to other signal-based algorithms is the application of musical knowledge for the identification process. The PianoTranscriber uses a limited set of the 88 musical notes of the standard piano. The extracted time series for all possible notes are used for a resynthesis step. Original and resynthesized signals are compared using an adapted onset-detection function. The PianoTranscriber was parametrized, optimized and evaluated using subsets of the publicly available MAPS-database. For the evaluation, the PianoTranscriber was compared to the state-of-the-art algorithm SONIC. The results show that the PianoTranscriber outperformed SONIC using base components from the analyzed piano and achieved similar results using base components from other pianos.
ANALYSIS OF ANTIOXIDANT AND ANTIDIABETIC ACTIVITY OF PIPER NIGRUM LEAF EXTRACT BY IN VITRO ASSAY

Diabetes shows damage of cells and organs due to improper sugar metabolism. It leads to oxidative damage which cause microvascular and macrovascular complications. It becomes requirement of drug development that act against hyperglycemia and oxidative damage, so the plants containing various bioactive compounds and minerals with less side effects were analyzed for drug development. Among various plants, the commonly used spices black pepper corn (Piper nigrum) is extensively used for various medicinal purposes traditionally. The compounds extracted from P. nigrum are used in many creams to treat various diseases at present selected for analysis. The leaf of Piper nigrum collected from karumandhuri and extracted with ethanol is used for further studies which showed antidiabetic and antioxidant activity in in vitro assay.
Cell shape recognition and segmentation in fluorescence microscopy images

Many cellular processes involve the translocation of proteins from the cytosolic region to the cortex of the cell and vice versa. The dynamics of such processes is typically investigated by fluorescence imaging of GFP-labeled versions of these proteins. Quantitative analysis of the resulting fluorescence images requires image segmentation procedures that identify the cell within the image and subsequently divide the cell into a cytosolic and a cortical region to monitor the temporal evolution of the fluorescence signals within these parts of the cell separately. Here, we present an image segmentation protocol that we have developed for this type of data analysis. It consists of noise reduction, normalization, and thresholding steps to generate masks that define the cytosolic and the cortical regions of a cell. Based on these masks, the desired fluorescence signals can be extracted from the confocal microscopy images.
MULTI-MODE ERROR FIELD CORRECTION ON THE DIII-D TOKAMAK

OAK A271 MULTI-MODE ERROR FIELD CORRECTION ON THE DIII-D TOKAMAK. Error field optimization on DIII-D tokamak plasma discharges has routinely been done for the last ten years with the use of the external ''n = 1 coil'' or the ''C-coil''. The optimum level of correction coil current is determined by the ability to avoid the locked mode instability and access previously unstable parameter space at low densities. The locked mode typically has toroidal and poloidal mode numbers n = 1 and m = 2, respectively, and it is this component that initially determined the correction coil current and phase. Realization of the importance of nearby n = 1 mode components m = 1 and m = 3 has led to a revision of the error field correction algorithm. Viscous and toroidal mode coupling effects suggested the need for additional terms in the expression for the radial ''penetration'' field B{sub pen} that can induce a locked mode. To incorporate these effects, the low density locked mode threshold database was expanded. A database of discharges at various toroidal fields, plasma currents, and safety factors was supplement4ed with data from an experiment in which the fields of the n = 1 coil and C-coil were combined, allowing the poloidal mode spectrum of the error field to be varied. A multivariate regression analysis of this new low density locked mode database was done to determine the low density locked mode threshold scaling relationship n{sub e} {proportional_to} B{sub T}{sup -0.01} q{sub 95}{sup -0.79} B{sub pen} and the coefficients of the poloidal mode components in the expression for B{sub pen}. Improved plasma performance is achieved by optimizing B{sub pen} by varying the applied correction coil currents.
Trousse d’outils de l’évaluation critique pour l’évaluation de plusieurs types de données probantes

Les professionnels de la santé sont souvent censés effectuer une évaluation critique de données probantes issues de la recherche afin de formuler des recommandations pour l’élaboration des pratiques et des politiques. Dans le présent numéro, nous décrivons la trousse d’outils de l’évaluation critique actuellement utilisée par l’Agence de la santé publique du Canada. La trousse d’outils comprend les éléments suivants : des algorithmes pour déterminer le type de plan d’étude, trois outils distincts (aux fins d’évaluation de la qualité des études analytiques, des études descriptives et des analyses documentaires), d’autres outils pour appuyer le processus d’évaluation, ainsi que des conseils pour effectuer la synthèse des données probantes et tirer des conclusions sur un ensemble de données probantes. Bien que la trousse d’outils ait été créée pour aider à l’élaboration de lignes directrices nationales relatives à la prévention et au contrôle des infections, les cliniciens, les responsables des politiques et les étudiants peuvent l’utiliser pour guider l’évaluation de toute recherche quantitative liée à la santé. Les participants à un essai pilote ont effectué 101 évaluations critiques, au total, et ont trouvé que la trousse d’outils était conviviale et utile dans le processus d’évaluation critique. Les commentaires des participants à l’essai pilote de la trousse d’outils ont permis d’éclairer davantage les révisions avant sa publication. La trousse d’outils s’ajoute à l’arsenal d’outils accessibles et peut s’avérer particulièrement utile lorsque les meilleures données probantes accessibles proviennent d’essais ou d’études non cliniques comportant des lacunes de conception, où d’autres outils peuvent ne pas être facilement appliqués.

The relationship between school-leaving examinations and university entrance assessments: The case of the South African system

Many higher education systems across the globe struggle with the challenges of low throughput rates and high dropout rates. It is estimated that more than half of South African Higher Education students drop out before completing their degree studies and only one in four students complete their undergraduate programmes in regulation time. Access, success and completion rates continue to be racially skewed. The challenges of these low throughput and high dropout rates along racial lines means that effective teaching and learning has to be a major focus for the higher education sector. In addition, extended degree programmes, where degrees are formally done over a longer period of time, have to be considered as part of the future higher education landscape in South Africa. One difficulty is determining which students will benefit from an extended programme. In South Africa there are two assessments of school-leavers that are pertinent to this difficulty. The first is the national school leaving examination, the National Senior Certificate (NSC), which is a statutory requirement for entry into Higher Education. The results of the NSC are norm-referenced (they yield an estimate of the position of the tested individual learner in relation to her peers) and are often difficult to interpret for the purposes of admission, placement and curriculum development. The second assessment is the National Benchmark Tests (NBTs). The NBTs are criterion-referenced (they generate a statement about the behaviour that can be expected of a person with a given score) and test students in three domains: Academic Literacy, Quantitative Literacy and Mathematics. This paper investigates the empirical relationship between the two assessments and argues that they should be seen as complementary in order to address the challenges of placing students in appropriate programmes and creating effective teaching and learning environments.
Assisted Arthrscopic Microfracture Treatment of Osteochondral Lesions of The Knee

Background: chondral injuries in the knee are a common source of pain and morbidity. Treatment of symptomatic chondral defects is challenging due to the limited healing capacity of articular cartilage. Microfracture is the most common surgical technique used to treat chondral defects in the knee and utilizes marrow stimulation to generate a fibrocartilage repair. Microfracture has demonstrated good short-term postoperative outcomes. Long-term outcomes following microfracture are variable, with loss of improvement attributed to the poor mechanical qualities of the fibrous repair tissue. Aim of the work: this prospective study with a 12 months follow-up was conducted to determine the efficacy of microfracture in the postoperative follow-up. We prospectively followed up these patients preoperatively and postopertively, clinically and radiologically. The final diagnosis was confirmed during arthroscopy. Patients and Methods: thirty symptomatic patients with articular cartilage defects of the knee were treated with the microfracture technique. Prospective evaluation of patient outcome was performed for a minimum follow-up of twelve months with a combination of validated outcome scores, subjective clinical rating and cartilage-sensitive magnetic resonance imaging. Results: at the time of the latest follow-up, knee function was rated good to excellent for twenty patients (60%), fair for four patients (13%) and poor for eight (26%). A lower body-mass index correlated with higher scores for the activities of daily living, with the worst results for patients with a body-mass index of >30 kg/m2. Significant improvement in the activities of daily living score was more frequent with a preoperative duration of symptoms of less than twelve months (p < 0.05). Magnetic resonance imaging in 15 knees demonstrated good healing in tissue fill of eight patients (54%), moderate fill in four (29%) and poor fill in three patients (17%). The fill grade was correlated with the knee function scores. All knees with good fill demonstrated improved knee function, whereas poor fill grade was associated with limited improvement and decreasing functional scores after twelve months. Conclusions: microfracture healing of articular cartilage lesions in the knee results in significant functional improvement at a minimum follow-up of one year. The best short-term results were observed with good fill grade, low body-mass index and a short duration of preoperative symptoms. A high body-mass index adversely affects short-term outcome, and a poor fill grade was associated with limited short-term durability.

Financial Inclusion in Asia-Pacific

Asia has made significant progress in financial inclusion, but both its across-country and intra-country disparities are among the highest in the world. The gaps between the rich and the poor, rural and urban populations, and men and women remain deep. Income is the main determinant of the level of financial inclusion; but other factors, such as geography, financial sector structure, and policies, also play important roles. While some countries in the Asia-Pacific region are leaders in fintech, on average the region lags behind others in several important areas such as online (internet) purchases, electronic payments, mobile money, and mobile government transfers. This Departmental Paper aims to take stock of the development and current state of financial inclusion and shed light on policies to advance financial inclusion in the region. The research focuses on the impact of financial inclusion on economic growth, poverty reduction, and inequality, linkages between financial inclusion and macroeconomic policies, as well as structural policies that are important for improving financial inclusion. Given the increasing importance of financial technologies (fintech), the paper also provides a snapshot of the fintech landscape in the Asia-Pacific.

The Effects of Heavy Metals on Denitrification in Wetland Sediment

Denitrification is an important process that helps to reduce soil sediments of nitrate. In a wetland environment denitrification process is a valuable process that helps to reduce nutrients build up that may result in algae bloom and with consequential ecosystem problems. The research “The effect of heavy metals on denitrification in wetland sediment” aimed at looking at how sediments with various load of heavy metals contaminants could affect the efficiency of denitrification process. The investigation was carried in the laboratory using sediments sampled from the constructed wetland in Linkoping, which receive effluents from sewage treatment plant. Wetland has a unique relevance both as a habitat for many species of plants and animals,but also a place for numerous biochemical processes.I am delighted to present you some of the findings and discussions. The book has element of environmental chemistry and will invaluable for teaching and learning in environmental science for colleges.I am highly grateful to the staff members of Water and Environmental Studies, Linkoping University, particularly Prof Bo Svensson for the supervision and suggestion.
