Demand for Beer in the Czech Republic : Understanding Long-Term On-and Off-Trade Price Elasticities

Grosová S. , Masár M. , Kutnohorská O. , Kubeš V. (2017): Demand for beer in the Czech Republic: understanding long-term onand off-trade price elasticities. Czech J. Food Sci., 35: 165–170. We provided estimates of price, cross-price, and income elasticities for onand off-trade beer consumption using econometric models on time series data from 1994 to 2014. The empirical results indicate that the most important determinants of on-trade demand are the price of off-trade beer, the price of substitutes and past consumption, while the income elasticity was not found to be important. The most important determinants of off-trade beer demand were the price of on-trade beer and the price of substitutes.
The Painlevé Analysis and Solutions with Critical Points

The Hénon–Heiles system in the general form has been considered. In a few nonintegrable cases with the help of the Painlevé test new solutions have been found as formal Laurent or Puiseux series, depending on three parameters. One of parameters determines a location of the singularity point, other parameters determine coefficients of series. The obtained series converge in some ring. For some values of these parameters the obtained Laurent series coincide with the Laurent series of the known exact solutions. 1 THE PAINLEVÉ PROPERTY AND INTEGRABILITY A Hamiltonian system in a 2s–dimensional phase space is called completely integrable (Liouville integrable) if it possesses s independent integrals which commute with respect to the associated Poisson bracket. When this is the case, the equations of motion are (in principal, at least) separable and solutions can be obtained by the method of quadratures. When we study some mechanical or field theory problem, we imply that time and space coordinates are real, whereas the integrability of motion equations is connected with the behavior of their solutions as functions of complex time and (in the case of the field theory) complex spatial coordinates. S.V. Kovalevskaya was the first, who proposed [1] (see also [2, 3]) to consider time as a complex variable and to demand that solutions of the E-mail: svernov@theory.sinp. msu.ru
Ultra Wide Band localization and tracking hybrid technique using VRTs

This research presents hybrid radar tracking technique consisting of Time Of Arrival (TOA) and Received Signal Strength (RSS) techniques. This hybrid design increases efficiency, accuracy and sensitivity of radar system. The radar used in this research is multistatic radar with one transmitter and three receivers. One common drawback in RSS and TOA techniques is high level synchronization in transmitter and receivers. The hybrid design also suffers from transmitter-receiver synchronization. To overcome TX-RX synchronization problem Virtual Reference Tags (VRTs) are used. These tags are virtually mapped over the surveillance area giving radar design different reference points from which it can accurately locate intruder and monitor its movements. Also four cases of different number of VRTs in design are discussed and based on simulation results accuracy of design is calculated.
Limits of Disclosure

Disclosure has its limits. One big focus of attention, criticism, and proposals for reform in the aftermath of the 2008 financial crisis has been securities disclosure. But most of the criticisms of disclosure relate to retail investors. The securities at issue in the crisis were mostly sold to sophisticated institutions. Whatever retail investors’ shortcomings may be, we would expect sophisticated investors to make well-informed investment decisions. But many sophisticated investors appear to have made investment decisions without making much use of the disclosure. We discuss another example where disclosure did not work as intended: executive compensation. The theory behind more expansive executive compensation disclosures was that shareholders might react to the disclosures with outrage and action, and companies, anticipating shareholder reaction, would curtail their compensation pre-emptively. But it was apparently not the reality and instead compensation spiraled higher. The two examples, taken together, serve to elucidate our broader point: underlying the rationale for disclosure are common sense views about how people make decisions — views that turn out to be importantly incomplete. This does not argue for making considerably less use of disclosure. But it does sound some cautionary notes. The strong allure of the disclosure solution is unfortunate, although perhaps unavoidable. The admittedly nebulous bottom line is this: disclosure is too often a convenient path for policymakers and many others looking to take action and hold onto comforting beliefs in the face of a bad outcome. Disclosure’s limits reveal yet again the need for a nuanced view of human nature that can better inform policy decisions.
A discursive perspective on legitimation strategies in multinational corporations

Few studies have examined legitimation in multinational corporations from a discursive perspective. To complement the existing institutional literature, we adopt a critical discourse analysis perspective that allows us to examine the microlevel processes of discursive legitimation. We provide an example of a media text— dealing with a production unit shutdown—to demonstrate how this perspective elucidates the various textual strategies used to legitimate multinational corporations' actions and their controversial consequences.
Knowledge of physiotherapy in the prevention and treatment of soccer injuries among managers of amateur soccer teams

This study was designed to evaluate the knowledge of physiotherapy among managers of amateur soccer teams in preventing and treating soccer injuries. A total of 32 amateur soccer team managers from Kano State, Nigeria were purposively recruited to participate in this study. Thereafter, a questionnaire seeking information on physiotherapy was administered. Data retrieved from the questionnaires were analysed using descriptive statistics of frequencies and percentages. The results of the study revealed that the average age of the participants was 47±8 years. The results also indicated that the majority (94%) of the participants were male, and 63% had post-secondary school qualifications. Working experience was generally low, mostly between one and two years. All the participants demonstrated good knowledge of the role of physiotherapy in preventing injuries (warm up and cool down exercises), as well as the means (use of exercise therapy and massage), indications (sprains, strains and back pain) and the modalities (ice sprays, exercise modalities and bandages). The major areas where lack of knowledge was evident were in the use of strapping (43.7%), the role of physiotherapy in health education (43.7%), and the use of electrical currents in physiotherapy (68.7%). The overall results showed that the average knowledge of the participants regarding the role of physiotherapy in preventing and treating soccer injuries was high (86.5%). It was concluded that a significant proportion of the managers of amateur soccer teams in Kano State have good knowledge of the use of physiotherapy in preventing and treating soccer injuries.

Erpetosuchus , a crocodile-like basal archosaur from the Late Triassic of Elgin , Scotland

Erpetosuchus , a small archosaurian reptile from the Late Triassic of Scotland and North America, has often been implicated in the ancestry of crocodilians. A restudy of the type specimen, using new high-fidelity casts, as well as examination of new, hitherto undescribed material, allows a detailed description and restoration of Erpetosuchus granti from the Lossiemouth Sandstone Formation (late Carnian, Late Triassic). This small reptile is known only from the front end of its body; a complete skull, cervical vertebral column, anterior dorsals and ribs, shoulder girdle, and forelimb. The skull shows a number of unusual features: a reduced row of only 4–5 teeth on the anterior part of the maxilla, a large antorbital fenestra set in a deep fossa whose margins are marked by distinct sharply angled ridges, a jugal that is divided into a lateral and a ventral portion by a sharp ridge, a deeply recessed tympanic area, the angular and surangular marked by a strong ridge running back from the ventral margin of the mandibular fenestra, and teeth oval in cross-section and lacking anterior and posterior carinae and marginal serrations. The remains suggest that Erpetosuchus was a light, cursorial animal that may have fed on insects. A cladistic analysis of crurotarsan archosaurs indicates that Erpetosuchus is the closest sister group of Crocodylomorpha among known basal archosaurs. It shares with them a deep recess in the cheek region framed by the quadrate and quadratojugal which slope forward side-by-side at an angle of 45 ° above horizontal, and reach the upper margin of the lower temporal fenestra. In Erpetosuchus the recess is entirely lateral, while in crocodylomorphs, the recess penetrates medially as well, since the quadrate/quadratojugal bar meets the side wall of the braincase. © 2002 The Linnean Society of London, Zoological Journal of the Linnean Society , 2002, 136 , 25–47.
Improvement of the Bitterness and Astringency of Green Tea by Sub-Critical Water Extraction

Green tea is known for its high content of functional catechins and is commonly consumed for its health-promoting effects. However, green tea catechins are highly bitter and astringent, and thus the development of products that can be consumed regularly is necessary for their efficient, routine intake. The aim of this study was to use sub-critical water extraction (SWE) to produce a green tea extract both less bitter and less astringent than typical green tea. Results from chemical evaluation using a taste sensor analyzer indicated that SWE reduced bitterness, astringency and unpleasant taste while it retained the original fragrance in the green tea extract. Furthermore, the SWE-produced extract had higher amounts of arginine and water-soluble pectin, which are thought to mask the bitterness and astringency of green tea.
Using WebSQL to Query the World Wide Web

The Internet is growing faster than ever, in an extremely decentralized (some would say anarchic) way, spanning over 130 countries and millions of users, covering every imaginable topic. Unfortunately this has caused some trouble (such as the “lost in hyperspace” syndrome), thus some researchers felt the need to uncover a structure of the World Wide Web (the major part of Internet), that would ease the search process.
A High Efficiency Li-Ion Battery LDO-Based Charger for Portable Application

This paper presents a high efficiency Li-ion battery LDO-based charger IC which adopted a three-mode control: trickle constant current, fast constant current, and constant voltage modes. The criteria of the proposed Li-ion battery charger, including high accuracy, high efficiency, and low size area, are of high importance. The simulation results provide the trickle current of 116 mA, maximum charging current of 448 mA, and charging voltage of 4.21 V at the power supply of 4.8–5 V, using 0.18 μm CMOS technology.
Implementation and Performance Assessment of Compressed Sensing for Images and Video Signals

Compressed sensing is an optimization based formalized framework based upon sub-Nyquist sampling principle of exploiting only the sparse signal of interest. It exploits the sparsity of the signal to reconstruct it from less number of measurements than required by the Nyquist sampling criteria. A nascent field of compressive sensing is explored in this paper for accurate acquisition and reconstruction of signals, images and video sequences. The algorithm is proposed for compression and efficient recovery of image and video based on the concept of compressive sensing. Three basic reconstruction techniques (Basic Pursuit ( l 1 ) Minimization, Least Square ( l 2 ) Minimization and Orthogonal Matching Pursuit) are applied on image samples and they are compared based on quality performance criteria. The performance parameters like compression ratio, peak signal to noise ratio and structural similarity index are evaluated for different image and video samples for critical analysis of these performance parameters is done for different reconstruction schemes. Finally it is concluded that compressive sensing based approach is better than the traditional compression schemes and Basic Pursuit ( l 1 ) methods gives the better image quality with a tradeoff among other parameters enabling faster acquisition, compression and reconstruction. Keywords: Compressed sensing, Sparsity, Structural similarity index, Basic Pursuit Minimization, Least Square Minimization and Orthogonal Matching Pursuit.
Dendrimer a versatile polymer in drug delivery

Dendrimers are a unique class of synthetic macromolecules having highly branched, three-dimensional, nanoscale architecture with very low polydispersity and high functionality. Structural advantages allow dendrimers to play an important role in the fields of nanotechnology, pharmaceutical and medicinal chemistry. This review discusses several aspects of dendrimers, including preparation, dendrimer-drug coupling chemistry, structural models of dendrimer-based drug delivery systems, and physicochemical and toxicological properties. Dendrimers have emerged as one of the most interesting themes for researchers as a result of their unique architecture and macromolecular characteristics. Several groups are involved in exploring their potential as versatile carriers in drug delivery. The use of dendrimers in drug delivery has been reviewed extensively. The increasing relevance of the potential of dendrimers in drug delivery emphasizes the need to explore the routes by which they can be administered. The high level of control possible over the architectural design ofdendrimers; their size, shape, branching length/density, and their surface functionality clearly distinguish these structures as unique and optimum carriers in those applications. The bioactive agents may be encapsulated into the interior of the dendrimers or chemically attached/physically adsorbed onto the dendrimer surface, with the option of tailoring the carrier to the specific needs of the active material and its therapeutic applications. This review clearly demonstrates the potential of this new fourth major class of polymer architecture and indeed substantiates the high hopes for the future of dendrimers.
X-ray emission regimes and rotation sequences in M 35 . An updated model of stellar activity evolution on the main sequence

Context. Late-type stars in young open clusters show two kinds of dependence of their X-ray emission on rotation. They also tend to group into two main sub-populations that lie on narrow sequences in diagrams where their rotation periods are plotted against their (B − V) colour indices. A correlation between these two regimes of X-ray emission and the rotation sequences has been recently observed in the M 34 open cluster. Sun-like M 34 stars also show a drop of their X-ray to bolometric luminosity ratio by about one order of magnitude at a Rossby number of about 0.3. Aims. The present study looks for similar connections between X-ray activity and rotation in an other open cluster. The aim is to consolidate a model of X-ray activity evolution on the main sequence and to provide observational constraints on dynamo processes in the interiors of late-type stars. Methods. The paper compares XMM-Newton measurements of X-ray stellar emission in M 35 with X-ray luminosity distributions derived from rotation period measurements assuming either an X-ray regime transition at a critical Rossby number or a correlation between X-ray emission regimes and rotation sequences. Results. This second hypothesis could account for the low number of M 35 stars detected in X-rays. A model of X-ray activity evolution is proposed based on the correlation. One major output is that the transition from saturated to non-saturated X-ray emission occurs at Rossby numbers between about 0.13 and 0.4 for each star depending on its mass and initial period of rotation on the ZAMS. This prediction agrees with observations of stellar X-ray emission in M 34. It explains the large range of X-ray luminosities observed among Sun-like stars in young open clusters. Conclusions. I conclude that the correlation between X-ray emission regimes and rotation sequences could be a fundamental property of the early evolution of stellar magnetic activity on the main sequence. I argue that the angular momentum redistribution mechanism(s) responsible for the transition between rotation sequences could result in a changing mixture of dynamo processes occurring side by side, possibly including a turbulent dynamo at high rotation rate and an interface-type dynamo whose efficiency decreases progressively at later stage of stellar evolution when rotation dies away.
Fractional-N PLL based FMCW sweep generator for an 80 GHz radar system with 24.5 GHz bandwidth

Abstract. A phase-locked loop (PLL) based frequency synthesizer capable of generating highly linear broadband frequency sweeps as signal source of a high resolution 80 GHz FMCW radar system is presented. The system achieves a wide output range of 24.5 GHz starting from 68 GHz up to 92.5 GHz. High frequencies allow the use of small antennas for small antenna beam angles. The wide bandwidth results in a radar system with a very high range resolution of below 1.5 cm. Furthermore, the presented synthesizer provides a very low phase noise performance of −80 dBc/Hz at 80 GHz carrier frequency and 10 kHz offset, which enables high precision distance measurements with low range errors. This is achieved by using two nested phase-looked loops with high order loop filters. The use of a fractional PLL divider and a high phase frequency discriminator (PFD) frequency assures an excellent ramp linearity.
Genetic parameters for piglet mortality, within litter variation of birth weight, litter size and litter birth weight.

Genetic parameters were estimated for litter traits from 2297 litters of 1767 sows from three maternal lines of a commercial breeding herd. Heritability estimates were 0.05 and 0.06 for total number of piglets born (NBT) and number of piglets that died per litter (NDIED). Heritabilities were higher for total litter weight (TLWB: 0.16), average piglet weight per litter (APWB: 0.31) and the harmonic mean (HMPWB: 0.28). Selection to reduce within litter variation is achievable given the heritability of 0.11 for coefficient of within litter variation (CVPWB). Litter size (NBT) was positively correlated with TLWB (rg: 0.54) and NDIED (rg: 0.76), but had no significant genetic relationships with the other traits. Litter mortality was negatively correlated (rg: -0.46) with APWB and HMPWB. HMPWB is genetically the same trait as APWB and does not provide additional information. The alternative description of within-litter variation (CVPWB) had no significant genetic correlation with other litter traits and provides little opportunity for genetic improvement of litter mortality. Instead, APWB should be considered in selection programs in addition to litter size to improve piglet weights and piglet survival.
Neighbourhood Effects and Cultural Exclusion

The idea of neighbourhood effects implies that the demographic context of poor neighbourhoods instills 'dysfunctional' norms, values and behaviours into youths, triggering a cycle of social pathology. It is argued that neighbourhood effects are part of a wider discourse of inner-city marginality that stereotypes inner-city neighbourhoods. Reflecting upon arguments made in the existing literature, the ideological underpinnings of the idea of neighbourhood effects are revealed. Essentialist conceptions of neighbourhood culture among employers, educators and institutional staff contribute to the neighbourhood effects phenomenon. It is also suggested that researchers and policy-makers must recognise wider forces of cultural differentiation and exclusion.
