Scorch marks from the sky

Daily sunshine duration is commonly reported at weather stations. Beyond the basic duration report, more information is available from scorched cards of Campbell-Stokes sunshine recorders, such as the estimation of direct-beam solar irradiance. Sunshine cards therefore potentially provide information on sky state, as inferred from solar-radiation data. Some sites have been operational since the late 19th century, hence sunshine cards potentially provide underexploited historical data on sky state. Sunshine cards provide an example of an archive source yielding data beyond the measurements originally sought.

Marks, spaces and boundaries

Dictionary compilers and designers use punctuation to structure and clarify entries and to encode information. Dictionaries with a relatively simple structure can have simple typography, and simple punctuation; as dictionaries grew more complex, and encountered the space constraints of the printed page, complex encoding systems were developed, using punctuation and symbols. Two recent trends have emerged in dictionary design: to eliminate punctuation, and sometimes to use a larger number of fonts, so that the boundaries between elements are indicated by font change, not punctuation.

Evidence-based psychological therapies: from bench to bedside

Patients with mental health difficulties do not always receive appropriate and recommended psychological treatment for their difficulties, and clinicians are not always appropriately trained to deliver them. This paper considers why this might be the case and provides an overview of the Charlie Waller Institute, a not-for-profit organisation funded by the NHS, University of Reading, and the Charlie Waller Memorial Trust. The Institute seeks to address this problem by training clinicians in wide variety of evidence-based therapies and assessing the impact of this training on clinician knowledge and skill.

Registering scents as community trade marks

While the registrability of scents as Community trade marks has become source of much controversy, the possibility of trademarking scents represents a great potential for the industry. In the aftermath of the Sieckmann case, which has raised the threshold of registrability for scent marks, companies have refrained from submitting new smell-mark applications. Despite the difficulties in registering scents as trademarks, however, it is not impossible to meet the Sieckmann criteria and file successful scent mark applications. This article explains how this could be possible; it reviews all objections in registering scents as trademarks and brings new light into this topic by way of a comprehensive analysis of the conditions under which scents can be registered as Community trade marks.

K-T transition in Deccan traps of central India marks major marine seaway across India.

Deccan intertrappean sediments in central India are generally considered as terrestrial deposits of Maastrichtian age, but the Cretaceous–Tertiary (K–T) position is still unknown. Here we report the discovery of the K–T transition, a marine incursion and environmental changes preserved within the intertrappean sediments at Jhilmili, Chhindwara District, Madhya Pradesh. Integrative biostratigraphic, sedimentologic, mineralogic and chemostratigraphic analyses reveal the basal Danian in the intertrappean sediments between lower and upper trap basalts that regionally correspond to C29r and the C29R/C29N transition, respectively. Intertrappean deposition occurred in predominantly terrestrial semi-humid to arid environments. But a short aquatic interval of fresh water ponds and lakes followed by shallow coastal marine conditions with brackish marine ostracods and early Danian zone P1a planktic foraminifera mark this interval very close to the K–T boundary. This marine incursion marks the existence of a nearby seaway, probably extending inland from the west through the Narmada and Tapti rift valleys. The Jhilmili results thus identify the K–T boundary near the end of the main phase of Deccan eruptions and indicate that a major seaway extended at least 800 km across India.

Barriers to “industrialisation” for interwar British retailing? The case of Marks & Spencer Ltd.

Research on international differences in retail productivity has highlighted formidable environmental barriers to the ‘industrialisation’ of mass retailing as a driver of declining British interwar productivity growth in this sector (and in services more generally). We examine evidence for such barriers, using a case study of a firm that built its interwar expansion strategy on ‘American’ retail methods – Marks & Spencer (M&S). We find that, rather than facing barriers to the adoption of American mass retail practices, M&S reaped major productivity gains from this process. This adds further evidence to an emerging literature rejecting the barriers to industrialisation thesis for retailing.

A comparison of two bench-scale anaerobic systems used for the treatment of dairy effluents

The objective of this work was to compare two anaerobic reactor conflgurations, a hybrid upflow anaerobic sludge blanket (UASBh) reactor and an anaerobic sequencing batch reactor with immobilised biomass (ASBBR) treating dairy effluents. The reactors were fed with effluent from the milk pasteurisation process (effluent 1-E1) and later with effluent from the same process combined with the one from the cheese manufacturing (effluent 2-E2). The ASBBR reactor showed average organic matter removal efficiency of 95.2% for E1 and 93.5% for E2, while the hybrid UASB reactor showed removal efficiencies of 90.3% and 80.1% respectively.

Real time video segmentation for recognising paint marks on bad wooden railway sleepers

Wooden railway sleeper inspections in Sweden are currently performed manually by a human operator; such inspections are based on visual analysis. Machine vision based approach has been done to emulate the visual abilities of human operator to enable automation of the process. Through this process bad sleepers are identified, and a spot is marked on it with specific color (blue in the current case) on the rail so that the maintenance operators are able to identify the spot and replace the sleeper. The motive of this thesis is to help the operators to identify those sleepers which are marked by color (spots), using an “Intelligent Vehicle” which is capable of running on the track. Capturing video while running on the track and segmenting the object of interest (spot) through this vehicle; we can automate this work and minimize the human intuitions. The video acquisition process depends on camera position and source light to obtain fine brightness in acquisition, we have tested 4 different types of combinations (camera position and source light) here to record the video and test the validity of proposed method. A sequence of real time rail frames are extracted from these videos and further processing (depending upon the data acquisition process) is done to identify the spots. After identification of spot each frame is divided in to 9 regions to know the particular region where the spot lies to avoid overlapping with noise, and so on. The proposed method will generate the information regarding in which region the spot lies, based on nine regions in each frame. From the generated results we have made some classification regarding data collection techniques, efficiency, time and speed. In this report, extensive experiments using image sequences from particular camera are reported and the experiments were done using intelligent vehicle as well as test vehicle and the results shows that we have achieved 95% success in identifying the spots when we use video as it is, in other method were we can skip some frames in pre-processing to increase the speed of video but the segmentation results we reduced to 85% and the time was very less compared to previous one. This shows the validity of proposed method in identification of spots lying on wooden railway sleepers where we can compromise between time and efficiency to get the desired result.

T&D-bench : explorando o espaço de projeto de processadores em ensino e em pesquisa

Uma metodologia de modelagem para a exploração do espaço de projeto de processadores é apresentada. A exploração do espaço de projeto constitui uma das etapas do fluxo de projeto dos atuais processadores de alto desempenho e de sistemas embarcados, que auxilia os projetistas no tratamento da complexidade inerente ao processo contemporâneo de projeto de sistemas computacionais. A principal característica desta metodologia é um processo de modelagem simples e rápido. Isso é obtido através da disponibilização dos recursos de modelagem em camadas com propósitos e níveis de complexidade de uso diferenciados e da limitação do número de elementos (palavras-chave, classes e métodos) que devem ser conhecidos pelo projetista para o acesso a estes recursos, independentemente da camada na qual eles se encontram. A única exigência para o uso de tais recursos são conhecimentos que estudantes de Computação adquirem ao longo dos seus cursos da área de Computação e Informática. Outras características da metodologia de modelagem incluem: recursos específicos e distintos para a descrição da organização, da arquitetura e de aspectos temporais do processador; um estilo de descrição estrutural de alto nível da organização; a possibilidade de uso de recursos gráficos em tempo de modelagem e em tempo de simulação; e a existência de informações nos modelos que podem ser usadas para a tradução das descrições para uma Hardware Description Language Todas estas características constituem um conjunto de soluções de modelagem e simulação de processadores que não é encontrado em outros ambientes usados na exploração do espaço de projeto, baseados em Architecture Description Languages, Hardware Description Languages e ferramentas de simulação. Além disso, os modelos de processadores, desenvolvidos com esta metodologia, fornecem os recursos para a aceleração do aprendizado de conteúdos de arquitetura de computadores que só são encontrados em simuladores para ensino. Uma infra-estrutura de software que implementa a metodologia de modelagem foi desenvolvida e está disponível. Ela foi usada no ensino e no contexto da pesquisa para a modelagem e simulação de diversos processadores. Uma comparação com a metodologia de modelagem de uma Architecture Description Language demonstra a simplicidade e a rapidez do processo de modelagem previsto na metodologia apresentada.

Training on synthetic ethylene-vinyl acetate bench model allows novice medical students to acquire suture skills

PURPOSE: To assess the acquisition of suture skills by training on ethylene-vinyl acetate bench model in novice medical students.METHODS: Sixteen medical students without previous surgery experience (novices) were randomly divided into two groups. During one hour group A trained sutures on ethylene-vinyl acetate (EVA) bench model with feedback of instructors, while group B (control) received a faculty-directed training based on books and instructional videos. All students underwent a both pre-and post-tests to perform two-and three-dimensional sutures on ox tongue. All recorded performances were evaluated by two blinded evaluators, using the Global Rating Scale.RESULTS: Although both groups have had a better performance (p<0.05) in the post-test when compared with the pre-test, the analysis of post-test showed that group A (EVA) had a better performance (p<0.05) when compared with group B (control).CONCLUSION: The ethylene vinyl acetate bench model allowed the novice students to acquire suture skills faster when compared to the traditional model of teaching.
