Discovering home : trail design for the Foothills, Lantzville BC
Creators: name: Sifton, Leigh-Kathleen
Publisher: name: University of British Columbia
Year: 2010

description: The Foothills in Lantzville, BC is a unique and beautiful place; stunning even. Admittedly, it presently takes a future vision to see its beauty. Heavily degraded by a history of forest operations, this site is in need of healing hands, engaged people who will help with the restoration work that the developers, Lantzville Foothills Estates Inc., are committed to completing. An inventory and mapping of the site in 2004 defined the site’s biophysical character. This information was used to define areas suitable for development and areas suitable for open space. As a result, of the 1826 acres that make up the Foothills, half has been set aside to become public park. This project is designed to help with insights, directions and design possibilities for the future core area of this park. This project is an attempt to connect people with this landscape through well thought out trail systems and facilities such that they will develop a connection to this place and will become engaged with the restoration and protection of the future park. Guiding principles were established to guide the design of interventions that minimize user impacts while creating opportunities for wonder and discovery. Facilities rest lightly on their site while being deeply rooted in their position in the greater landscapes. Trails, designed by linking key features with appropriate sequencing, speak to the uniqueness of this landscape. Discovering Home provides an illustration of an approach to trail design that should be undertaken in the rest of the park at The Foothills.
Coupling local to global star formation in spiral galaxies: the effect of differential rotation

description: Star formation is one of the key factors that shapes galaxies. This process is relatively well understood from both simulations and observations on a small "local" scale of individual giant molecular clouds and also on a "global" galaxy-wide scale (e.g. the Kennicutt-Schmidt law). However, there is still no understanding on how to connect global to local star formation scales and whether this connection is at all possible. Here we analyze spatially resolved kinematics and the star formation rate density $Σ_{SFR}$ for a combined sample of 17 nearby spiral galaxies obtained using our own optical observations in H$α$ for 9 galaxies and neutral hydrogen radio observations combined with a multi-wavelength spectral energy distribution analysis for 8 galaxies from the THINGS project. We show that the azimuthally averaged normalized star formation rate density in spiral galaxies on a scale of a few hundred parsecs is proportional to the kinetic energy of giant molecular cloud collisions due to differential rotation of the galactic disc. This energy is calculated from the rotation curve using the two Oort parameters A and B as $\log (Σ_{SFR} / SFR_{tot}) \propto \log[2 A^2+ 5 B^2]$. The total kinetic energy of collision is defined by the shear velocity that is proportional to A and the rotational energy of a cloud proportional to the vorticity B. Hence, shear does not act as a stabilizing factor for the cloud collapse thus reducing star formation but rather increases it by boosting the kinetic energy of collisions. This result can be a tool through which one can predict a radial distribution of star formation surface density using only a rotation curve.

description: The purpose of the article was comparing diverse resources of production factors in farming and displaying relations between them, as well as the effectiveness of their exploitation in agricultural regions of the European Union (EU-25). An average arable farm was analyzed in 122 regions, inspecting the inputs of land and labour, the size and structure of production, costs, subsidies flows, and in the end the income situation. The allocation and effectiveness of production factors in agricultural EU regions were compared. The author is putting up questions, to what extent the European regions differ with respect to the use of these factors as well as whether it is possible to find among them some spatial resemblances. She found also causes of their diversity taking different factors into account. / Synopsis. Celem niniejszego artykułu jest przedstawienie zróżnicowania zasobów czynników produkcji zaangażowanych w produkcję rolną oraz relacji zachodzących między nimi, a także efektywności ich wykorzystania w regionach Unii Europejskiej (UE-25). Analizie poddano przeciętne gospodarstwo rolne w 122 regionach, badając nakłady ziemi, pracy, wielkość i strukturę produkcji, koszty, strumienie dopłat i w końcu jego sytuację dochodową. Celem badania było porównanie alokacji i efektywności wspomnianych czynników produkcji w rolnictwie regionów UE. Autorka stawia pytanie, na ile regiony europejskie różnią się względem wykorzystania tychże czynników oraz czy można znaleźć podobieństwa przestrzenne. Doszukuje się także przyczyn owego zróżnicowania uwzględniając różnorakie czynniki.

The value and structure of Polish exports to Russia and imports of agri-food products from Russia per sections of CN nomenclature were characterized. The share of agri-food products in the total value of Polish exports to Russia and imports from Russia was determined. The analysis of strengths and weaknesses as well as opportunities and threats in trading with Russia were presented. / Synopsis. Analiza wymiany towarowej w zakresie produktów rolno-spożywczych pomiędzy Polską a Rosją za latach 1997-2008 wykazała, iż wymianę tę charakteryzuje po stronie polskiej przewaga eksportu nad importem, a zatem dodatnie saldo handlu tymi towarami. Średni udział artykułów rolno-spożywczych w ogólnej strukturze polskiego eksportu do Rosji na przełomie lat 1997-2008 ukształtował się na poziomie około 23%, podczas gdy import z Rosji na poziomie niewiele przekraczającym 1%. Spośród czterech sekcji produktów rolno-spożywczych największy udział w eksporcie z Polski do Rosji przypada na sekcję IV, tj. przetwory spożywcze, zaś najmniejszy na sekcję III, tj. tłuszcze i oleje. Po stronie szans polskiego eksportu towarów rolno-spożywczych do Rosji, które należałoby wykorzystać, można wskazać m.in. położenie geograficzne tego kraju, potencjał ekonomiczny, rozmiar i chłonność rynku oraz pozycję na arenie międzynarodowej, a także starania Rosji o wejście w struktury WTO, wzrost zamożności rosyjskiego społeczeństwa oraz brak samowystarczalności żywnościowej. Niestety obok szans istnieje także wiele zagrożeń oraz słabych stron polskiego eksportu do Rosji.

description: The last important price changes within the food delivery chain caused a growth of food prices and a higher inflation rate. In the face of those circumstances the activities for improvement of food delivery chain have become very important, since it affects directly all citizens. The analysis have displayed that the global competitiveness of food delivery chain and its growth did not equal the competitiveness and growth of whole economy. In the period of 2003-2008, the dynamics of growth of production in food delivery chain was clearly lower than the changes of production in other sectors of economy. The average growth rate of added value in the food delivery chain sectors was by about 2 per cent lower than the average growth rate in the EU economy. Furthermore, some attention was paid to an uneven distribution of added value between the participants in the food delivery chain. / Synopsis. Odnotowane w ostatnich latach znaczne wahania cen w ramach łańcucha dostaw żywności doprowadziły do wzrostu konsumpcyjnych cen żywności i wyższej inflacji. W takiej sytuacji bardzo ważne stały się działania mające na celu usprawnienie funkcjonowania łańcucha żywnościowego, który bezpośrednio oddziałuje na wszystkich obywateli. Przeprowadzona analiza wskazuje, że ogólna konkurencyjność łańcucha dostaw żywności i jego wzrost nie dorównuje konkurencyjności i wzrostowi całej gospodarki UE. W latach 2003–2008 tempo wzrostu produkcji w łańcuchu dostaw żywności było wyraźnie słabsze w stosunku do zmian produkcji w pozostałych sektorach gospodarki. Średni wzrost wartości dodanej sektorów wchodzących w skład łańcucha dostaw żywności był przeciętnie o 2% rocznie niższy niż średni jej wzrost odnotowywany w UE. Ponadto zwrócono uwagę na nierównomierny podział wartości dodanej między poszczególnymi uczestnikami łańcucha.

description: The investigation concerned 41 milk cooperatives in years 2002-2005. The results indicate that Polish accession to the European Union positively influenced the levels of sales profitability, assets value, own capital and employment. The degree of current liquidity slightly diminished but that of cash liquidity increased. All those levels were maintained within standard limits. The surveyed dairies improved their financial efficiency after the accession through faster recovering of money engaged in current assets. Their average indebtedness slightly increased but it did not concern the long term indebtedness which stayed at the same level. Their ability to serve the indebtedness was weak although it improved in the majority of cases. / Synopsis. Badaniami objęto 41 spółdzielni mleczarskich w okresie czterech lat (2002-2005). Badania wykazały, że wejście Polski do UE miało pozytywny wpływ na poziomy rentowności sprzedaży, majątku, kapitału własnego i zatrudnienia. Stopień płynności bieżącej i szybkiej z czasem uległ nieznacznemu obniżeniu, a gotówkowej podwyższeniu. Jednak poziomy te utrzymały się w granicach dla nich standardowych. Badane mleczarnie po wejściu Polski do UE poprawiły swoją sprawność finansową przez szybsze odzyskiwanie środków pieniężnych zaangażowanych w aktywa obrotowe. Wzrosło nieznacznie ich średnie zadłużenie, jednak nie dotyczyło ono zadłużenia długoterminowego, które pozostało na niezmienionym poziomie. Ich zdolność do obsługi zadłużenia była słaba, chociaż poprawiła się w większości przypadków.

description: Cu$_{0.5}$Co$_{0.5}$Cl$_{2}$-FeCl$_{3}$ graphite intercalation compound is a three-dimensional short-range Ising spin glass with a spin freezing temperature $T_{c}$ ($= 3.92 \pm 0.11$ K). The stability of the spin glass phase in the presence of a magnetic field $H$ is examined from (i) the spin freezing temperature $T_{f}(ω,H)$ at which the differential field-cooled (FC) susceptibility $\partial M_{FC}(T,H)/\partial H$ coincides with the dispersion $χ^{\prime}(ω,T,H=0)$ with the angular frequency $ω$, and (ii) the time dependence of zero-field cooled (ZFC) susceptibility $χ_{ZFC}$ after a ZFC aging protocol with a wait time $t_{W}$ ($= 1.0 \times 10^{4}$). The relaxation rate $S(t)$ (= d$χ_{ZFC}$/d$\ln t$) exhibits a local maximum at a characteristic time $t_{cr}$, reflecting non-equilibrium aging dynamics. The peak time $t_{cr}(T,H)$ decreases with increasing $H$ at the fixed temperature $T$ (2.9 K $\leq T

description: We study the longitudinal stability of beam-plasma systems in the presence of a density inhomogeneity in the background plasma. Previous works have focused on the non-relativistic regime where hydrodynamical models are used to evolve pre-existing Langmuir waves within inhomogeneous background plasmas. Here, for the first time we study the problem with kinetic equations in a fully-relativistic way. We do not assume the existence of Langmuir waves, and we focus on the rate and the mechanism by which waves are excited in such systems from an initial perturbation. We derive the structure of the unstable modes and compute an analytical approximation for their growth rates. Our computation is limited to dilute and cold beams, and shows an excellent agreement with particle-in-cell simulations performed using the SHARP code. We show that, due to such an inhomogeneity, the virulent beam-plasma instabilities in the intergalactic medium are not suppressed but their counterparts in the solar wind can be suppressed as evidenced by propagating type-III solar radio bursts.

The research was conducted in 140 entities in Mazovia province in 2011. The length of the cash conversion cycle period was influenced the most by the level of inventories and short-term liabilities due credits and loans. The possible changes in that area could be beneficial for companies efficiency. Estimated multiple regression model with the cash conversion cycle as dependent variable noted negative relation with return on assets. Capital structure of the enterprises influenced the cash conversion cycle stronger than the structure of their assets.

The yields of these plants is extensively dependent on pollination effected by insects. The value of pollination of those plants was about 950 million PLN (estimated by value of production method) and 1,1 billion PLN (estimated by replacement value method). The highest values, in using value of production method, were obtained for sweet cherry orchards (about 40 thousands PLN), sour cherry orchards (about 25 thous. PLN) and gooseberry (about 20 thous. PLN), and the lowest for strawberries (about 5 thous. PLN) and currants (about 7 thous. PLN). In the case of the replacement value method the highest value of pollination were obtained for currants (about 25 thous. PLN), strawberries and raspberries (each about 15 thous. PLN), and lowest for pear orchards (about 7 thous. PLN) and apple orchards (about 8 thous. PLN).

description: The axion-gravity Chern-Simons coupling is well motivated but is relatively weakly constrained, partly due to difficult measurements of gravity. We study the sensitivity of LIGO measurements of chirping gravitational waves (GWs) on such coupling. When the frequency of the propagating GW matches with that of the coherent oscillation of axion dark matter field, the decay of axions into gravitons can be stimulated, resonantly enhancing the GW. Such a resonance peak can be detected at LIGO as a deviation from the chirping waveform. Since all observed GWs will undergo similar resonant enhancement from the Milky-Way (MW) axion halo, LIGO O1+O2 observations can potentially provide the strongest constraint on the coupling, at least for the axion mass $m_a = 5 \times 10^{-13} - 5 \times 10^{-12}$ eV. Along the course, we also emphasize the relevance of the finite coherence of axion fields and the ansatz separating forward and backward propagations of GWs. As a result, the parity violation of the Chern-Simons coupling is not observable from chirping GWs.

Altered B cell Toll-like Receptor 9 responses after the onset of paediatric chronic graft-versus host disease
Creators: name: She, Kevin
Publisher: name: University of British Columbia
Year: 2010

description: Chronic Graft-versus-Host disease (cGVHD) is a major complication after blood and marrow transplantation (BMT). B cells appear to play a role in cGVHD as evidenced in murine models and supported clinically by the success of B cell depletion treatment. Immunostimulatory microbial CpG-DNA responses are enhanced in splenocytes from mice with simulated Graft-versus Host Disease and we hypothesized that a similar response to CpG by B cells may be present in human cGVHD. Peripheral B cells from newly diagnosed cGVHD patients enrolled on the COG protocol ASCT0031 were divided into early (3-8 months post-BMT) and late (9 months post-BMT) onset groups and compared to time-matched control patients. A significantly greater percentage of B cells from cGVHD patients rapidly responded to phosphorothioate modified CpG compared to controls. There was a significant correlation between TLR9 expression and CpG response, also confirmed using entirely TLR9 dependent native phosphodiester CpG. There were no differences in response to peptidoglycan (TLRZ, 6) or LPS (TLR4). Patients with hepatic involvement had stronger phosphodiester CpG response. These findings suggest that a larger pool of B cells from patients with cGVHD are specifically primed for TLR9 response, compared to patients who have not developed extensive cGVHD after allogeneic BMT, and may play a role in the pathophysiology or maintenance of cGVHD.

Our work is motivated by an analogy of Schrodinger's cat paradox, where the state corresponding to the virtual cat is a mixed thermal state with a large average photon number. Remarkably, quantum entanglement can be produced between thermal states with nearly the maximum Bell-inequality violation even when the temperatures of both modes approach infinity.

The aim of the study was to evaluate the impact of real estate development of agricultural Treasury agrarian structure in the Warmia-Masuria province. The analyzes used data from the reports on the activities of the Agricultural Property Agency in the years 1992- 2013, the CSO statistics and results of research conducted among tenants and buyers of agricultural land of the Treasury. Investigations show that the changes in the agrarian structure is influenced by state policy regarding the development of the agricultural system, the economic conditions of agricultural production, the availability of agricultural land for development (lease or purchase) and the economic and financial situation of the farms.

description: The aim of the article was to present the state of implementation of obligatory and non-obligatory food health safety and food quality management systems in the food industry in Poland. The study included all companies (by groups and classes of PKD) operating in Poland, and subject to oversight by the State Sanitary Inspection and Veterinary Inspection. In the food production it is obligatory to implement and maintain GHP, GMP and HACCP. Starting from the Polish accession to the European Union has been a significant increase in the number of companies that have implemented and maintain obligatory quality management systems. The study, however, shows that in 2012 the obligatory HACCP system was implemented and maintained only by 63% of companies processing non-animal products and only by 50% of companies processing animal by-products. Non-obligatory quality management systems were implemented by less than 5% of the total number of food industry companies.
title: 'Challenge and Change in a Cinderella Service': A History of Fulbourn Hospital, Cambridgeshire, 1953 – 1995
Creators: name: Adams, John Stephen
Publisher: name: The Open University
Year: 2009

description: This study of Fulbourn Hospital uses oral history and documentary sources to explore the models of mental illness and the therapeutic practices associated with them in one provincial English psychiatric hospital during the second half of the twentieth century. The appointment in 1953 of a new Medical Superintendent from the Maudsley Hospital, Dr David Clark, set in train a process of change which transformed the hospital through the implementation of a social model of psychiatry. This period was ended by the appointment of the leading biological psychiatrist, Professor Sir Martin Roth, as the University of Cambridge’s first Professor of Psychiatry in 1976. The subsequent years saw the appointment of psychiatrists who shared support for a medical model of psychiatry. Attention then turned to the development of care in the community through the establishment of group homes and community mental health teams. The implementation of sectorisation proved to be controversial, as did the increasing role afforded to general managers. It is concluded that many of the elements of the social model introduced by Dr Clark became absorbed into the working practices of the nursing staff, after they had been abandoned by the psychiatrists working in the hospital. This study therefore illustrates the process through which professional boundaries shifted in response to changing models of practice.

description: The purpose of the research is to assess determinants of competition in the social market economy and enterprises. Two research methods was applied: literature review and benchmarking. The results of conducted analysis indicate that the social market economy based on free competition creates better conditions of economy development than neo-liberalism, providing the balance between private and social aims and higher consistency with sustainable development theory. Interference of market mechanism with administrative competition reduces effectiveness of public support and its transparency and social justice.

description: Focusing on an improved approximation scheme, we present how to treat the centrifugal and the Coulombic behavior terms and then to obtain the bound state solutions of the Klein-Gordon (KG) equation with the Manning-Rosen plus a Class of Yukawa potentials. By means of the Nikiforov-Uvarov (NU) and supersymmetric quantum mechanics (SUSYQM) methods, we present the energy spectrum for any $\ell$-state and the corresponding radial wave functions in terms of the hypergeometric functions. From both methods we obtain the same results. Several special cases for the potentials which are useful for other physical systems are also discussed. These are consistent with those results in previous works. We obtain that the energy level $E$ is sensitive to the potential parameter $δ$ at fixed values of other parameters and increases when $δ$ runs from $0.05$ to $0.3$. Furthermore, $E$ is sensitive to the quantum numbers $\ell$ and $n_r$ for a given $δ$, as expected.

description: In this paper we present an approach to quantum cloning with unmodulated spin networks. The cloner is realized by a proper design of the network and a choice of the coupling between the qubits. We show that in the case of phase covariant cloner the XY coupling gives the best results. In the 1->2 cloning we find that the value for the fidelity of the optimal cloner is achieved, and values comparable to the optimal ones in the general N->M case can be attained. If a suitable set of network symmetries are satisfied, the output fidelity of the clones does not depend on the specific choice of the graph. We show that spin network cloning is robust against the presence of static imperfections. Moreover, in the presence of noise, it outperforms the conventional approach. In this case the fidelity exceeds the corresponding value obtained by quantum gates even for a very small amount of noise. Furthermore we show how to use this method to clone qutrits and qudits. By means of the Heisenberg coupling it is also possible to implement the universal cloner although in this case the fidelity is 10% off that of the optimal cloner.

description: The purpose of the paper was to asses changes of competitiveness among three bio-products: winter wheat, winter rye and winter rape in the year 2008 and 2011. The main research method was a comparative analysis of absolute and relative competitiveness among these bio-products in the given year. In the year 2008 winter rape had an absolute advantage over the other crops, followed by winter wheat and winter rye that took the second and third places respectively. In that year the hierarchy of crops according to the relative competitive advantage criterion was as follows: winter wheat, winter rape and winter rye. In the year 2011 the criterion of absolute advantage between these bio-products yielded the following order: wheat, rape and rye, whereas the criterion of relative advantage: wheat, rye and rape. The highest impact on the improvement of economic benefits of an agricultural holding has the bio-product characterized with the relative and absolute advantage, followed by the one with the relative advantage.

description: Nanostructured surfaces are known to provide excellent optical properties for various photonics devices. Fabrication of such nanoscale structures to germanium (Ge) surfaces by metal assisted chemical etching (MACE) is, however, challenging as Ge surface is highly reactive resulting often in micron-level rather than nanoscale structures. Here we show that by properly controlling the process, it is possible to confine the chemical reaction only to the vicinity of the metal nanoparticles and obtain nanostructures also in Ge. Furthermore, it is shown that controlling the density of the nanoparticles, concentration of oxidizing and dissolving agents as well as the etching time plays a crucial role in successful nanostructure formation. We also discuss the impact of high mobility of charge carriers on the chemical reactions taking place on Ge surfaces. As a result we propose a simple one-step MACE process that results in nanoscale structures with less than 10% surface reflectance in the wavelength region between 400 nm and 1600 nm. The method consumes only a small amount of Ge and is thus industrially viable and also applicable to thin Ge layers.

Markov-chain reconstruction of the 2dF Galaxy Redshift Survey real-space power spectrum

description: The real-space power spectrum of L* galaxies measured from the 2dF Galaxy Redshift Survey (2dFGRS) is presented. Markov-Chain Monte-Carlo (MCMC) sampling was used to fit radial and angular modes resulting from a Spherical Harmonics decomposition of the 2dFGRS overdensity field (described in Percival et al. 2004) with 16 real-space power spectrum values and linear redshift-space distortion parameter β(L*,0). The recovered marginalised band-powers are compared to previous estimates of galaxy power spectra. Additionally, we provide a simple model for the 17 dimensional likelihood hyper-surface in order to allow the likelihood to be quickly estimated given a set of model band-powers and β(L*,0). The likelihood surface is not well approximated by a multi-variate Gaussian distribution with model-independent covariances. Instead, a model is presented in which the distribution of each band-power has a Gaussian distribution in a combination of the band-power and its logarithm. The relative contribution of each component was determined by fitting the MCMC output. Using these distributions, we demonstrate how the likelihood of a given cosmological model can be quickly and accurately estimated, and use a simple set of models to compare estimated likelihoods with likelihoods calculated using the full Spherical Harmonics procedure. All of the data are made publically available (from http://www.roe.ac.uk/~wjp/, enabling the Spherical Harmonics decomposition of the 2dFGRS of Percival et al. (2004) to be easily used as a cosmological constraint.

title: Analysing the requirements for monitoring and switching: A problem-oriented approach
Creators: name: Salifu, Mohammed
Publisher: name: The Open University
Year: 2008

description: Context-aware applications monitor changes in their environment and switch their behaviour in order to continue satisfying requirements. Specifying monitoring and switching in such applications can be difficult due to their dependence on varying environmental properties. Two problems require analysis: the detection of changes in the operating environment to assess their impact on requirements satisfaction, and the adaptation of application behaviour to ensure requirements satisfaction. This thesis borrows from the world of problem-oriented software system development and product-lines to analyse monitoring and switching problems on one hand and contextual changes on the other. It proposes a shift of focus from treating monitoring and switching as activities to be analysed as part of the design, to treating them as part of the problem whose requirements are analysed. We claim three novel contributions: (1) we provide concepts and mechanisms for analysing monitoring and switching problems in context; (2) we formulate and prove two theorems for monitoring and switching, which define the necessary and sufficient conditions for monitoring a contextual variable and for switching application behaviour to restore requirements satisfaction when they are violated; and (3) we provide a tool for automated derivation of the conditions for monitoring and switching. Our approach is evaluated using two case studies of a proof of concept mobile phone productline and a logistics company that delivers and monitors products across the UK. We found the applications of the approach to be effective in analysing unforeseen requirements violations caused by changes in the systems operating environments. Furthermore, the monitoring and switching mechanisms derived from the analysis enabled the software to become, to some extent, context-aware.
