Portwest’s future strategy: Achieving €1Billion Turnover – Portwest and the Global Workwear Market

Portwest is a global manufacturer and innovator of workwear, safetywear and PPE and one of the fastest growing workwear companies in the world. The company has pursed growth successfully for the last 20 years, successfully employing new market entry strategies along with strategic acquisitions to gain footholds in over 130 countries worldwide. The company has also maintained a vertically integrated supply chain, owning factories and distribution centres. Growth can come at a cost- increasingly complex operations, a growing product portfolio and an increased exposure to risk in terms of business continuity. Should Portwest continue to aggressively target growth through new territories, or consolidate existing markets and streamline existing operations

Portwest’s Future Strategy: Fashionising Workwear – Threading The Needle

Portwest- should they further pursue the leisurewear / workwear market or should they focus on expanding the current range? Portwest is a global manufacturer and innovator of workwear, safetywear and Personal protective equipment (PPE) and one of the fastest growing workwear companies in the world. Recently, the company launched an “Inspired Workwear” collection targeting the leisurewear/workwear market. It is a departure from their traditional markets where their acquisition strategy has seen Portwest rapidly gain market share. Management are concerned that this new departure may take resources from the core business of Workwear and dilute key resources

Fish assemblages of an artificial reef in Posidonia oceanica (L.) Delile, 1813 meadow off the southern Balearic Islands (western Mediterranean)

The fish assemblage associated with an artificial reef composed of small blocks (12 m³) with high structural complexity set in a Posidonia oceanica (L) Delile, 1813 meadow has been studied for 2 years by means of visual censuses. The fish assemblage was dominated qualitatively by species with medium home ranges living; in the surrounding areas of the blocks (mainly Labridae species), and numerically by schooling mid water species. After 38 months of deployment the progressive colonisation of species living on the blocks and the surrounding areas was still ongoing. The colonisation process interacts with seasonal changes, and no clear variations in the fish community variables were observed. The type of block used and the situation of the reef seem inappropriate to the aims for which it was deployed.La evolución de la comunidad íctica de un arrecife artificial situado sobre pradera de Posidonia oceanica (L.) Delile, 1813 y formado por pequeños bloques (12 m³) de gran complejidad estructural se ha estudiado mediante censos visuales durante dos años. Cualitativamente la comunidad íctica está dominada por especies con desplazamientos medios que viven en las proximidades de los módulos (principalmente lábridos) y cuantitativamente por especies gregarias que se distribuyen en la columna de agua. A los 38 meses del fondeo del arrecife aun se observa la colonización de los bloques por especies que viven en sus proximidades o sobre los mismos. El proceso de colonización interacciona con las variaciones estacionales, no observándose una tendencia clara en los parámetros poblacionales. El tipo de módulo utilizado y la localización del arrecife no parecen ser apropiados para la consecución de los objetivos perseguidos en su inmersión.Instituto Español de Oceanografí

The Mars Climate Database

The Mars Climate Database (MCD) [1] is a database of statistics describing the climate and environment of the Martian atmosphere. It was constructed directly on the basis of output from mulitannual integrations of two general circulation models (GCMs)developed by Laboratoire de Météorologie Dynamique du CNRS, France, the University of Oxford, UK, and Instituto de Astrofisica de Andalucia, Spain, with support from the European Space Agency (ESA) and Centre National d–Etudes Spatiales (CNES). A description of the MCD is given along with a comparison between spacecraft observations of Mars and results predicted at similar locations and times in the MCD. The MCD can be used as a tool for mission planning and has been applied to prepare for several missions in Europe and the USA. It also provides information for mission design specialists on the mean state and variability of the Martian environment from the surface to above 120km. The GCMs on which the database is founded, include a set of physical parameterizations (radiative transfer in the visible and thermal infrared ranges, turbulent mixing, condensation-sublimation of CO2, thermal conduction in the soil and representation of gravity waves) and two different codes for the representation of large scale dynamics: a spectral code for the AOPP version and a grid-point code for the LMD version. The GCMs correctly reproduce the main meteorological features of Mars, as observed by the Mariner 9 and Viking orbiters, the Viking landers, and Mars Global Surveyor (MGS). As well as the standard statistical measures for mission design studies, the MCD includes a novel representation of large-scale variability, using empirical eigenfunctions derived from an analysis of the full simulations, and small-scale variability based on parameterizations of processes such as gravity wave propagation. The database allows the user to choose from 5 dust storm scenarios including a best guess, default scenario, deduced from recent MGS observations, an upper boundary for an atmosphere without dust storms, as observed by Viking the landers, and a clear, cold, lower boundary scenario, as observed by Phobos 2 and from Earth. The full version of the MCD is available on CDROM (for UNIX systems and PCs) and is also accessible through an interactive WWW interface at http://www-mars.lmd.jussieu.fr/

Atomic step motion during the dewetting of ultra-thin films

We report on three key processes involving atomic step motion during the dewetting of thin solid films: (i) the growth of an isolated island nucleated far from a hole, (ii) the spreading of a monolayer rim, and (iii) the zipping of a monolayer island along a straight dewetting front. Kinetic Monte Carlo results are in good agreement with simple analytical models assuming diffusion-limited dynamics.Comment: 7 pages, 5 figure

Neutrino physics at accelerators

Present and future neutrino experiments at accelerators are mainly concerned with understanding the neutrino oscillation phenomenon and its implications. Here a brief account of neutrino oscillations is given together with a description of the supporting data. Some current and planned accelerator neutrino experiments are also explained.Comment: 23 pages, 24 figures. Talk given at the Corfu Summer Institute on Elementary Particle Physics 200

End-to-End V2X Latency Modeling and Analysis in 5G Networks

networks provide higher flexibility and improved performance compared to previous cellular technologies. This has raised expectations on the possibility to support advanced Vehicle to Everything (V2X) services using the cellular network via Vehicle-to-Network (V2N) and Vehicle-to-Network-to-Vehicle (V2N2V) connections. The possibility to support critical V2X services using 5G V2N2V or V2N connections depends on their end-to-end (E2E) latency. The E2E latency of V2N2V or V2N connections depends on the particular 5G network deployment, dimensioning and configuration, in addition to the network load. To date, few studies have analyzed the capabilities of V2N2V or V2N connections to support critical V2X services, and most of them focus on the 5G radio access network or consider dedicated 5G pilot deployments under controlled conditions. This paper progresses the state-of-the-art by introducing a novel E2E latency model to quantify the latency of 5G V2N and V2N2V communications. The model includes the latency introduced at the radio, transport, core, Internet, peering points and application server (AS) when vehicles are supported by a single mobile network operator (MNO) and when they are supported by multiple MNOs. The model can quantify the latency experienced when the V2X AS is deployed from the edge of the network (using MEC platforms) to the cloud. Using this model, this study estimates the E2E latency of 5G V2N2V connections for a large variety of possible 5G network deployments and configurations. The analysis helps identify which 5G network deployments and configurations are more suitable to meet V2X latency requirements. To this aim, we consider as case study the cooperative lane change service. The conducted analysis highlights the challenge for centralized network deployments that locate the V2X AS at the cloud to meet the latency requirements of advanced V2X services. Locating the V2X AS closer to the cell edge reduces the latency. However, it requires a higher number of ASs and also a careful dimensioning of the network and its configuration to ensure sufficient network and AS resources are dedicated to serve the V2X traffic

Two-loop two-point functions with masses: asymptotic expansions and Taylor series, in any dimension

In all mass cases needed for quark and gluon self-energies, the two-loop master diagram is expanded at large and small $q^2$, in $d$ dimensions, using identities derived from integration by parts. Expansions are given, in terms of hypergeometric series, for all gluon diagrams and for all but one of the quark diagrams; expansions of the latter are obtained from differential equations. Pad\'{e} approximants to truncations of the expansions are shown to be of great utility. As an application, we obtain the two-loop photon self-energy, for all $d$, and achieve highly accelerated convergence of its expansions in powers of $q^2/m^2$ or $m^2/q^2$, for $d=4$.Comment: 25 pages, OUT--4102--43, BI--TP/92--5

Factors related to attitudes toward organ donation after death in the immigrant population in Spain

The version posted must contain the text: This is the accepted version of the following article: [full citation], which has been published in final form at [Link to final article]Considering the relevance of the migratory processes in Western societies, the attitudes toward organ donation after death are analyzed bymeans of a survey applied to a representative random sample of the resident immigrant population in Spain, comprising 1202 subjects (estimated marginof error of ±2.88%, p = q, p < 0.05). Considered variables were disposition toward own organ donation, disposition toward deceased relatives donation in different situations, arguments against donation, socio-demographic indicators, religious beliefs, social integration, and information about organ donation and transplantation. Predisposition to donate varies strongly across geographical origin and religious beliefs and also shows relationships with additional socio-demographic, social integration, and informative variables. In turn, the relationship between religious beliefs and attitude toward donation varies as a function of the degreeof social integration. In Spain, the immigrant population is a heterogeneous collective that requires differential strategies to promote donation. Such strategies should be aimed at reinforcing the existing positive attitudes ofcitizens from West Europe and Latin America, and at familiarizing and informing about donation in citizens from the East, and at making specific efforts to break down the cultural and religious barriers toward donation in African citizens, with special emphasis on people of the Muslim faith
