description: Με θεωρητική βάση μια βιβλιογραφία σχετική με θέματα “δεικτών μιζέριας”, κοινωνικής ευημερίας και “δεικτών θυσίας”, συγκεντρώνονται στοιχεία για την ανεργία, τον πληθωρισμό και τον ρυθμό μεγέθυνσης του Α.Ε.Π. για 21 χώρες του Οργανισμού Οικονομικής Συνεργασίας και Ανάπτυξης (Ο.Ο.Σ.Α.) από το 1960 ως το 2007 με σκοπό την κατασκευή των κατά Okun και Barro “δεικτών μιζέριας”. Απομονώνοντας 12 ευρωπαϊκές χώρες της ευρωζώνης εξετάζεται η επίπτωση της εισαγωγής του ευρώ πάνω στον σταθερό όρο και την τάση των χρονολογικών σειρών των δύο “δεικτών μιζέριας” με τον έλεγχο εξωγενών διαρθρωτικών μεταβολών Phillips –Perron.Τα αποτελέσματα δείχνουν πως 8 από τις 12 χώρες της ευρωζώνης δέχονται διαρθρωτικές μεταβολές στους δύο “δείκτες μιζέριας” τους την χρονιά που εφαρμόστηκε το ενιαίο νόμισμα. Οι μεγάλες μαζί με τις μικρές χώρες βιώνουν μια βελτίωση της κοινωνικής τους ευημερίας, μέσω της μείωσης του σταθερού όρου των χρονολογικών σειρών των δύο “δεικτών μιζέριας”, και έναν απότομο επιχειρηματικό κύκλο, μέσω αύξησης της τάσης των χρονολογικών σειρών των εν λόγω δεικτών. Οι μεσαίες χώρες βιώνουν μια χειροτέρευση της κοινωνικής τους ευημερίας, λόγω αύξησης του σταθερού όρου των χρονολογικών σειρών των δύο “δεικτών μιζέριας”, και έναν ομαλό επιχειρηματικό κύκλο, λόγω μείωσης της τάσης των χρονολογικών σειρών των εν λόγω δεικτών.
description: Based on a bibliography relative to ΄΄misery indicators’΄΄, social welfare’s and sacrifice ratios’ issues, data about unemployment level, inflation and growth rate of GDP is collected for 21 OECD countries from 1960 until 2007 in order to construct the Okun’s and Barro’s ΄΄misery indicators΄΄. As we focus on 12 European countries of euro zone, we examine the consequences of euro’s adoption to the constant and trend component of the time series of the two types of ΄΄misery indicators΄΄, with a Phillips- Perron exogenous structural break test. The results show that 8 out of 12 countries of euro zone face a structural break to their ΄΄misery indicators’΄΄ time series the year when the single currency was adopted. Both the strong and the less strong countries take advantage of an improvement of their social welfare, through the reduction of the constant component of ΄΄misery indicators’΄΄ time series and also experience a vertical business cycle, through the trend component’s increase. The intermediate strong countries face a worsening of their social welfare because of the increase of constant component of time series of the ΄΄misery indicators΄΄ and also experience a smooth business cycle because of the reduction of the trend component of time series of the ΄΄misery indicators΄΄.

Description
Tatia neivai is distinguished from the other species of the genus by its colour pattern with dark flanks bearing small white horizontally elongated dots, different in small specimens (fig. 5). The species is also distinguished by the presence of a broad third nuchal plate, with a short lateral projection and the cranial fontanel bound by mesethmoid and frontal. Morphometric data are presented in table 1.
Habitat
Most of the environments where T. neivai was found had sandy and rocky bottom with fast flowing water, excluding Nemesio Parma and Ituzaingó in which the water is quiet with submerged allochthonous vegetation and sandy and muddy bottom.
Distribution
Tatia neivai is known from the upper Paraguay and Paraná river, and upper Paraíba do Sul in Brazil (Sarmento-Soares & Martins-Pinheiro, 2008). The specimens collected herein come from several streams and the main channel of the middle río Paraná (fig. 7).

description: Για την περιγραφή και την εκτίμηση της συμπεριφοράς πληθυσμιακών συστημάτων χρησιμοποιούνται συνήθως ατομικά δεδομένα. Ωστόσο, σε αρκετές περιπτώσεις τα διαθέσιμα δεδομένα είναι συλλογικά και είναι δύσκολο να εκτιμηθεί η επιμέρους ατομική συμπεριφορά. Για την αντιμετώπιση των περιπτώσεων αυτών αναπτύχθηκαν τεχνικές με τη γενική ονομασία «οικολογική ανάλυση», οι οποίες κάτω από συγκεκριμένες προϋποθέσεις ανασυνθέτουν την ατομική συμπεριφορά. Ένα από τα βασικότερα προβλήματα οικολογικής ανάλυσης είναι η εκτίμηση των ρυθμών μετακίνησης ψήφων από εκλογικά αποτελέσματα. Στα πλαίσια αυτής της εργασίας αναπτύχθηκε ένα πρόγραμμα που υλοποιεί τη μέθοδο VTR, που επιλύει το προαναφερθέν πρόβλημα.
description: For describing and estimating the behaviour of demographic systems we usually use individual data. However, in many cases the available data are collective and it is difficult to estimate the individual behaviour. For the confrontation of this cases there were techniques developed with the general name "ecological inference", which under concrete conditions recompose the individual behaviour. One of the basic problems of ecological inference is the estimation of voter transition rates from electoral results. In this paper was developed a program that implemented the VTR method, which solves the above problem.

description: We propose a classification of exoplanet atmospheres based on their H, C, O, N element abundances below about 600 K. Chemical equilibrium models were run for all combinations of H, C, N, O abundances, and three types of solutions were found, which are robust against variations of temperature, pressure and nitrogen abundance. Type A atmospheres contain H2O, CH4, NH3 and either H2 or N2, but only traces of CO2 and O2. Type B atmospheres contain O2, H2O, CO2 and N2, but only traces of CH4, NH3 and H2. Type C atmospheres contain H2O, CO2, CH4 and N2, but only traces of NH3, H2 and O2. Other molecules are only present in ppb or ppm concentrations in chemical equilibrium, depending on temperature. Type C atmospheres are not found in the solar system, where atmospheres are generally cold enough for water to condense, but exoplanets may well host such atmospheres. Our models show that graphite (soot) clouds can occur in type C atmospheres in addition to water clouds, which can occur in all types of atmospheres. Full equilibrium condensation models show that the outgassing from warm rock can naturally provide type C atmospheres. We conclude that type C atmospheres, if they exist, would lead to false positive detections of biosignatures in exoplanets when considering the coexistence of CH4 and CO2, and suggest other, more robust non-equilibrium markers.

A {\it distribution} on the boundary $\partialΔ$ of the universal covering tree $Δ$ is an $\mathfrak M$-valued measure defined on clopen sets. If $\mathfrak M$ has no $χ(\mathcal G)$-torsion then the group of $Γ$-invariant distributions on $\partialΔ$ is isomorphic to $H_1(\mathcal G,\mathfrak M)$.

Η κεραία που σχεδιάστηκε και μελετήθηκε αποτελείται από ένα συμβατικό μεταλλικό επίπεδο γείωσης, δύο διηλεκτρικά υποστρώματα και μία σύνθεση τριών ομόκεντρων μικροταινιακών δακτυλίων στην άνω επιφάνεια του πάνω υποστρώματος. Στο σύστημα ενσωματώθηκε περιμετρικά της κεραίας ηλεκτρομαγνητική δομή EBG. Οι δακτύλιοι της κεραίας συνδέονται αγώγιμα μεταξύ τους, τροφοδοτούνται από δύο πρόμπες και συντονίζουν σε τρεις συχνοτικές περιοχές (GSM900, GSM1800, 2.4GHz). Η σχεδίαση έγινε με βάση την πλήρη κυματική θεωρητική ανάλυση τυπωμένων στοιχείων. Η προσομοίωση της δομής της μικροταινιακής κεραίας έγινε μέσω του λογισμικού . HFSS Η μελέτη έδειξε ότι η παρουσία του EBG υποστρώματος προκαλεί αύξηση του συχνοτικού εύρους ζώνης κατά 10.4% στα GSM900, αύξηση της απολαβής ισχύος κατά 0.57dB στα GSM1800 και κατά 4.31dB στα 2.4 GHz. Επίσης, στις συχνότητες συντονισμού, παρατηρήθηκε μείωση της έκτασης των περιοχών της μέγιστης έντασης του κοντινού ηλεκτρικού πεδίου προς την πλευρά του χρήστη.
description: The subject of the master thesis, was the study of the influence of the presence of an EBG substrate to the operational characteristics of a printed antenna, and the potential to suppress the radiated power towards the side of the user. The designed antenna consists of a conventional metallic ground plane, two dielectric layer substrates and a structure of three concentric, microstrip annular rings (patches) on the upper surface of the upper substrate. Moreover, an electromagnetic EBG structure was embedded perimetrically to the antenna. The antenna rings are conductively connected, they are fed by two probes of 50Ω impedance and operates in three frequency bands (GSM900, GSM1800, 2.4GHz). The design was based on full wave theoretical analysis of printed elements. The simulation of the structure was made by the HFSS software. The study proved that the presence of an EBG substrate, leads to the increase of the frequency bandwidth for 10.4% at GSM900, the increase of the gain of the system for 0.57dB at GSM1800 and 4.31dB at 2.4GHz. It was also observed a significant suppression of the size of the areas of maximum radiation in the near zone field towards the user.

description: A computational strategy for the evaluation of the crystal lattice constants and cohesive energy of the weakly bound molecular solids is proposed. The strategy is based on the high level ab initio coupled-cluster determination of the pairwise additive contribution to the interaction energy. The zero-point-energy correction and non-additive contributions to the interaction energy are treated using density functional methods. The experimental crystal lattice constants of the solid benzene are reproduced, and the value of 480 meV/molecule is calculated for its cohesive energy.
Line dancing : an atlas of geography curriculum and poetic possibilities
Creators: name: Hurren, Wanda Jean
Publisher: name: University of British Columbia
Year: 2009

description: The words, legends, maps, post-cards, and poems within this study are an exploration of geography curriculum, poetics, and embodied knowledge. There are three main sections and a supplement to this atlas. The first section is an exploration of semiotic theory and the notion of poetics. I inquire into structures of signification, the relationship between our words and our worlds, and the spaces of possibility that relationship opens for the inclusion of embodied knowing. The second section of this atlas is an exploration of geography curriculum in British Columbia and Saskatchewan, and of recent developments within academic human geography writ large, regarding existing constructions of geography and poetics and embodied knowledge. An attention to language, writing, and embodied knowledge can be found within academic geography, yet these same concerns have not been considered within Canadian curricular geography. The third section of this atlas is an exploration of post-structural approaches to reading/writing, and poetic possibilities on a personal level. Within this section, poetic language is explored as a genre for facilitating embodied knowledge within geography curriculum. The supplement to the atlas is a part of the atlas that finishes the form, and was written in an interpretive, poetic, and playful spirit. The underlying premise of this research is that how we write the world affects and reflects in the same instant how we understand and live in the world (our words and worlds perform a mingling dance of signification); therefore, attending to how we graphy the geo is of curricular concern (especially if we consider that curriculum provides the medium for us to understand self and world). Transformation of geography curriculum, and an inclusion of embodied approaches to (re)writing the world of curriculum theory (and dissertations) are the aims of this research.
Magnetic properties and the electronic structure of LiCoO_2

description: We have described properties of LiCoO_2 within the Quantum Atomistic Solid State (QUASST) theory taking into account very strong electron correlations, predominantly of the intra-atomic origin, spin-orbit coupling and the detailed local crystallographic surroundings and its symmetry. Properties of LiCoO_2 are consistently explained together with NaCoO_2 and LaCoO_3 - in all of these compounds the Co^3+ ions occur in the low-spin state. This low-spin state is the effect of the relatively strong crystal-field interactions (B_4^z = +320 K <=> 10Dq = 3.3 eV) and is a manifestation of the very large orbital moment of the Co^3+ ion.

description: An important question in representative democracies is how to determine the optimal parliament size of a given country. According to an old conjecture, known as the cubic root law, there is a fairly universal power-law relation, with an exponent close to 1/3, between the size of an elected parliament and the country's population. Empirical data in modern European countries support such universality but are consistent with a larger exponent. In this work, we analyze this intriguing regularity using tools from complex networks theory. We model the population of a democratic country as a random network, drawn from a growth model, where each node is assigned a constituency membership sampled from an available set of size $D$. We calculate analytically the modularity of the population and find that its functional relation with the number of constituencies is strongly non-monotonic, exhibiting a maximum that depends on the population size. The criterion of maximal modularity allows us to predict that the number of representatives should scale as a power-law in the size of the population, a finding that is qualitatively confirmed by the empirical analysis of real-world data.

description: The concepts of pole mass and width are extended to unstable fermions in the general framework of parity-nonconserving gauge theories, such as the Standard Model. In contrast with the conventional on-shell definitions, these concepts are gauge independent and avoid severe unphysical singularities, properties of great importance since most fundamental fermions in nature are unstable particles. General expressions for the unrenormalized and renormalized dressed propagators of unstable fermions and their field-renormalization constants are presented.

A tale of three psyches : reflecting on art education as journey work in words and imagery
Creators: name: Major, Diane
Publisher: name: University of British Columbia
Year: 2009

description: Art education has the potential to change the world. How art changed worlds — mine and those of the people in my art classes — unfolds here through text, fonts and images. These words and images try to touch upon "the intangible benefits" Wilson (1994) of art education. Art education that opens to the search for personal meaning through the wow of engaged experience, extends the content of traditional art education and operates with an awareness of the art as therapy is art as journey work. Journey work invites students to trust their unique vision of the world and in so doing moves towards social change by questioning dominant power-over structures through fostering power-from-within. Reflecting on the voices of the women i interviewed, on my personal journals and on discussions with my colleagues and friends, i interrogated my own art education practice. An interview-based methodology using memories and art work as key points for reflection, reflective research offers an intimate understanding of a classroom through stories and memories of three participants, two students and myself as teacher. Our participation in an on-going dialogue of friendship before and after interviews gives resonance and depth to our discussions. Weaving together my students' stories, my own life story, and theory brings the personal into the academic. The analysis section seeks relationships between these personal stories and the culture in which we are embedded, and concludes the personal is more than political, it is ecological: what we do to ourselves, we do to the web; what we do to the web, we do to ourselves.

description: We conducted a search for brown dwarfs (BDs) and very low mass (VLM) stars in the 625 Myr-old Hyades cluster in order to derive the cluster's mass function across the stellar-substellar boundary. We performed a deep (I=23, z=22.5) photometric survey over 16 sq.deg. around the cluster center, followed up with K-band photometry to measure the proper motion of candidate members, and optical and near-IR spectroscopy of probable BD and VLM members. We report the discovery of the first 2 brown dwarfs in the Hyades cluster. The 2 objects have a spectral type early-T and their optical and near-IR photometry as well as their proper motion are consistent with them being cluster members. According to models, their mass is 50 Jupiter masses at an age of 625 Myr. We also report the discovery of 3 new very low mass stellar members of the cluster, and confirm the membership of 16 others. We combine these results with a list of previously known cluster members to build the present-day mass function (PDMF) of the Hyades cluster from 50 Jupiter masses to 3Mo. We find the Hyades PDMF to be strongly deficient in very low mass objects and brown dwarfs compared to the IMF of younger open clusters such as the Pleiades. We interpret this deficiency as the result of dynamical evolution over the past few 100 Myr, i.e., the preferential evaporation of low mass cluster members due to weak gravitational encounters. We thus estimate that the Hyades cluster currently hosts about 10-15 brown dwarfs, while its initial substellar population may have amounted up to 150-200 members.

description: The Wheeler equation, for electromagnetic disturbances in a gravitational field, was found by Fiziev to have exact solutions both above and below the event horizon, in the form of waves propagating both inwardly and outwardly. This observation can be interpreted and verified from the optical point of view, entirely on the basis of the Schwarzschild metric for length contraction and time dilation, in order to derive a differential version of Snell's law for the Schwarzschild black hole. It reveals interesting physics, including the correct amount of light deflection by the Sun, internal and external Oppenheimer-Snyder cones of the black hole, properties of its phonon sphere and the conclusion that light-rays are kept below the horizon by length contraction and time dilation rather than deflection.

description: We provide a new interpretation of ultraviolet transition region emission line widths observed by the SUMER instrument on the Solar and Heliospheric Observatory (SOHO). This investigation is prompted by observations of the chromosphere at unprecedented spatial and temporal resolution from the Solar Optical Telescope (SOT) on Hinode revealing that all chromospheric structures above the limb display significant transverse (Alfvenic) perturbations. We demonstrate that the magnitude, network sensitivity and apparent center-to-limb isotropy of the measured line widths (formed below 250,000K) can be explained by an observationally constrained forward-model in which the line width is caused by the line-of-sight superposition of longitudinal and Alfvenic motions on the small-scale (spicular) structures that dominate the chromosphere and low transition region.

description: Magnetic fields in galaxies and galaxy clusters are amplified from a very weak seed value to the observed $μ{\rm G}$ strengths by the turbulent dynamo. The seed magnetic field can be of primordial or astrophysical origin. The strength and structure of the seed field, on the galaxy or galaxy cluster scale, can be very different, depending on the seed-field generation mechanism. The seed field first encounters the small-scale dynamo, thus we investigate the effects of the strength and structure of the seed field on the small-scale dynamo action. Using numerical simulations of driven turbulence and considering three different seed-field configurations: 1) uniform field, 2) random field with a power-law spectrum, and 3) random field with a parabolic spectrum, we show that the strength and statistical properties of the dynamo-generated magnetic fields are independent of the details of the seed field. We demonstrate that, even when the small-scale dynamo is not active, small-scale magnetic fields can be generated and amplified linearly due to the tangling of the large-scale field. In the presence of the small-scale dynamo action, we find that any memory of the seed field for the non-linear small-scale dynamo generated magnetic fields is lost and thus, it is not possible to trace back seed-field information from the evolved magnetic fields in a turbulent medium.

description: Μια αντικειμενική μη επεμβατική μέθοδος αναπτύχθηκε για την ταυτοποίηση ατόμων καφέ αρκούδας μέσω των βιομετρικών χαρακτηριστικών των ιχνών τους. Μετρήθηκαν 24 διαστάσεις (16 στα ίχνη, 8 στους διασκελισμούς) σε ίχνη εμπρόσθιων πελμάτων 11 ατόμων (7 ραδιοσημασμένα, 4 άγνωστα) στην κεντρική Πίνδο. Για τη μείωση των μετρήσεων πραγματοποιήθηκε πολλαπλή παλινδρόμηση ώστε να παραληφθούν οι παράμετροι που σχετίζονται γραμμικά και διαφέρουν από το δεξί στο αριστερό πέλμα. Για την επιλογή των σημαντικότερων βιομετρικών χαρακτηριστικών ενός ίχνους και τον υπολογισμό του αριθμού των ιχνών που πρέπει να μετρούνται ανά άτομο δημιουργήθηκαν δέντρα απόφασης. Για τη διερεύνηση της σχέσης των βιομετρικών χαρακτηριστικών του ίχνους και των σωματομετρικων χαρακτηριστικών του ζώου πραγματοποιήθηκε ανάλυση συσχέτισης σε δεδομένα 23 ατόμων καφέ αρκούδας. Βρέθηκε ότι (α) οι σημαντικότερες παράμετροι για την ταυτοποίηση των ζώων ήταν το πλάτος, το νύχι βάση 2, το πλάτος εξωτερικού δαχτύλου και ο αριστερός διασκελισμός με ποσοστό ακρίβειας έως και 94%, (β) πρέπει να μετρούνται τουλάχιστον 7 ίχνη ανά άτομο και (γ) υπάρχει αντιστοιχία σωματικών χαρακτηριστικών του ζώου με το πλάτος του ίχνους. Τα θετικά, οι περιορισμοί και οι πρακτικές εφαρμογές της μεθόδου αναλύονται σε σχέση με τη παρακολούθηση των πληθυσμών καφέ αρκούδας.
description: An objective, non-invasive technique was developed for identifying individual brown bears from their footprints. Measurements of 24 dimensions (16 on footprints, 8 on strides) of footprints of the front feet of 11 individuals (7 radiomarked, 4 unknown) in central mount Pindos were taken. Multiple regression analysis was used to remove correlated variables. The remaining variables did not differ between left and right footprints. To examine which of the features of the footprint might provide a distinctive geometrical profile of a particular animal and the number of the tracks that should be measured per individual, decision trees were created. To examine the relationship between the features of the footprint and the body dimensions of the individual, correlation analysis was applied on a set of data for 23 brown bears. Results: (a) the most important measurements for the identification of individuals were the width of the track, the nail - base 2 distance, the width of outer finger and the left stride, (b) the minimum number of tracks that should be measured per person was estimated to be equal with 7, (c) statistically significant correlation was found between the front foot width and particular body dimensions. The advantages, limitations and practical applications of the track identification technique are discussed in relation to monitoring brown bear populations.

description: A method for concatenating quantum error-correcting codes is presented. The method is applicable to a wide class of quantum error-correcting codes known as Calderbank-Shor-Steane (CSS) codes. As a result, codes that achieve a high rate in the Shannon theoretic sense and that are decodable in polynomial time are presented. The rate is the highest among those known to be achievable by CSS codes. Moreover, the best known lower bound on the greatest minimum distance of codes constructible in polynomial time is improved for a wide range.

description: The element-specific technique of x-ray magnetic circular dichroism (XMCD) is used to directly determine the magnitude and character of the valence band orbital magnetic moments in (III,Mn)As ferromagnetic semiconductors. A distinct dichroism is observed at the As K absorption edge, yielding an As 4p orbital magnetic moment of around -0.1 Bohr magnetons per valence band hole. This is strongly influenced by strain, indicating its crucial influence on the magnetic anisotropy. The dichroism at the Ga K edge is much weaker. The K edge XMCD signals for Mn and As both have positive sign, which indicates the important contribution of Mn 4p states to the Mn K edge spectra.

description: context: The spectrum of IRAS 16594-4656 shows shock excited H_2 emission and collisionally excited emission lines such as[O I],[C I],and [Fe II]. aim: The goal is to determine the location of the H_2 and [Fe II] shock emission, to determine the shock velocities,and constrain the physical properties in the shock. methods: High resolution spectra of the H_2 1-0 S(1),H_2 2-1 S(1), [Fe II], and Pa$β$ emission lines were obtained with the near infrared spectrograph Phoenix on Gemini South. results: The position-velocity diagrams of H_2 1-0 S(1), H_2 2-1 S(1), and [Fe II] are presented. The H_2 and [Fe II] emission is spatially extended. The collisionally excited [O I] and [C I] optical emission lines have a similar double peaked profile compared to the extracted H_2 profile and appear to be produced in the same shock. They all indicate an expansion velocity of ~8 km/s and the presence of a neutral, very high density region with $n_{\rm e}$ about 3 x 10^6 to 5 x10^7 cm$^{-3}$. The [Fe II] emission however is single peaked. It has a gaussian FWHM of 30 km/s and a total width of 62 km/s at 1% of the peak. The Pa$β$ profile is even wider with a gaussian FWHM of 48 km/s and a total width of 75 km/s at 1% of the peak. conclusions: The H$_2$ emission is excited in a slow 5 to 20 km/s shock into dense material at the edge of the lobes, caused by the interaction of the AGB ejecta and the post-AGB wind. The 3D representation of the H_2 data shows a hollow structure with less H_2 emission in the equatorial region. The [Fe II] emission is not present in the lobes, but originates close to the central star in fast shocks in the post-AGB wind or in a disk. The Pa$β$ emission also appears to originate close to the star.

description: We present and analyze a minimalist model for the vertical transport of people in a tall building by elevators. We focus on start-of-day operation in which people arrive at the ground floor of the building at a fixed rate. When an elevator arrives on the ground floor, passengers enter until the elevator capacity is reached, and then they are transported to their destination floors. We determine the distribution of times that each person waits until an elevator arrives, the number of people waiting for elevators, and transition to synchrony for multiple elevators when the arrival rate of people is sufficiently large. We validate many of our predictions by event-driven simulations.

description: When discriminating between two pure quantum states, there exists a quantitative tradeoff between the information retrieved by the measurement and the disturbance caused on the unknown state. We derive the optimal tradeoff and provide the corresponding quantum measurement. Such an optimal measurement smoothly interpolates between the two limiting cases of maximal information extraction and no measurement at all.

description: A particle $ϕ$ coupling to two photons couples also to charged particles, like protons, through a loop. If the particle is a light scalar this induced coupling to protons leads to non-newtonian forces. We show that the experimental constraints on exotic, fifth-type forces lead to stringent constraints on the $ϕγγ$ coupling.

description: Gamma ray bursts (GRBs) are astronomical phenomena detected at highest energies. The gamma ray photons carry energies on the order of mega-electronovolts and arrive to us from the point-like sources that are uniformly distributed on the sky. A typical burst has a form of a pulse that lasts for about a minute. As the Earth atmosphere is not transparent to the very high energy radiation, the bursts are detected by means of the telescopes onboard satellites that are placed on the orbit. The total energetics of GRB events, which is given by the integrated energy flux by the detector unit area, implies that we are witnessing very powerful explosions, where an enormously great power is released within a short time. There is only one way to obtain such huge energies in cosmos: the disruption of a star.
