Microscopy techniques for determining water–cement (w/c) ratio in hardened concrete: A round-robin assessment
No full textWater to cement (w/c) ratio is usually the most important parameter specified in concrete design and is sometimes the subject of dispute when a shortfall in concrete strength or durability is an issue. However, determination of w/c ratio in hardened concrete by testing is very difficult once the concrete has set. This paper presents the results from an inter-laboratory round-robin study organised by the Applied Petrography Group to evaluate and compare microscopy methods for measuring w/c ratio in hardened concrete. Five concrete prisms with w/c ratios ranging from 0.35 to 0.55, but otherwise identical in mix design were prepared independently and distributed to 11 participating petrographic laboratories across Europe. Participants used a range of methods routine to their laboratory and these are broadly divided into visual assessment, measurement of fluorescent intensity and quantitative backscattered electron microscopy. Some participants determined w/c ratio using more than one method or operator. Consequently, 100 individual w/c ratio determinations were collected, representing the largest study of its type ever undertaken. The majority (81%) of the results are accurate to within ± 0.1 of the target mix w/c ratios, 58% come to within ± 0.05 and 37% are within ± 0.025. The study shows that microscopy-based methods are more accurate and reliable compared to the BS 1881-124 physicochemical method for determining w/c ratio. The practical significance, potential sources of errors and limitations are discussed with the view to inform future applications.Materials and Environmen
Inferred hybridisation, sympatry and movements of Chorister Robin-Chat Cossypha dichroa and Red-capped Robin-Chat C. natalensis
No full textInferred hybrid Chorister Robin-Chat Cossypha dichroa and Red-capped Robin-Chat C. natalensis have previously only been recorded from the Eastern Cape province, South Africa. We extend the occurrence of inferred hybrids with ringed and photographed examples from KwaZulu-Natal and Limpopo provinces. Sympatry at a fine scale was investigated at Vernon Crookes Nature Reserve, KwaZulu-Natal, using observational data over 30 years (1978–2008) and intensive mist-netting during two field-trips in June and October 2010. Both robin-chat species were found throughout the year and occurred in the same forest patches. Inferred hybrids are known from five different forest patches in Vernon Crookes, three with photographic evidence. During winter an increase in Chorister Robin-Chat numbers was detectable both from mist-netting and checklist data. An increase of Red-capped Robin-Chats was observed from mist-netting and more equivocally from checklist data in spring. Red-capped and Chorister Robin-Chats are sympatric along the eastern escarpment of South Africa, with co-occurrence in 96 quarter degree squares from Southern African Bird Atlas Project 1 data. During the breeding season, co-occurrence was recorded in 62 quarter degree squares and in nine grid-cells evidence of breeding by both species is available. Hybridisation may be more common along the extensive area of sympatry than currently realised. OSTRICH 2011, 82(3): 231–24
Claudia Nickolaus, Robin Hood's women : a practice in historical thinking and its classroom implications
No full textMany people and cultures around the world celebrate the legend of Robin Hood, or someone like him. Many also celebrate the classic romance between Robin and his beloved Maid Marian. What many do not necessarily think about is the portrayal of women in the countless tales of Robin Hood, or how the historical context surrounding each tale influences its characterization of the women within them. Author after author has used this hero's life to communicate ideas and values about the relationships between men and women in their own time. Why should the context of each tale matter? I explore both the depiction and historical context of female characters in Howard Pyle's The Merry Adventures of Robin Hood (1883) and Howard Green's The Adventures of Robin Hood (1956) as a practice in what it means to think historically. Following my analysis, I put the research to work with a compilation of practical classroom implications for teachers of history, thus demonstrating the universal need and value of historical thinking and inquiry.Thesis (B.?)Honors Colleg
From crop left-overs to nutrient resource: growth-stimulating potential of biochar in nutrient solutions for wheat soilless cultivation systems
No full textTo reach the estimated food demands for 2050 in decreasingly suiting climates, current agricultural techniques have to be complemented by sustainably intensified practices. The current study repurposed wheat crop residues into biochar, and investigated its potential in different plant cultivation systems, including a hydroponic cultivation of wheat. Biochars resulting from varying pyrolysis parameters including feedstock composition (straw and chaff) and temperature (450°C and 600°C), were tested using a fast plant screening method. Biochar WBC450, produced from a combination of chaff and straw at 450°C, was selected for further plant experiments, and used in a static leaching experiment in the Arabidopsis thaliana cultivation medium. Increased pH and EC were observed, together with an increase of most macronutrient (K, Mg, P, S) and a decrease of most micronutrient (Fe, Mn, Zn) concentrations. Considering plant growth, application of biochar resulted in concentration-dependent effects in both tested plant species (A. thaliana and wheat). It improved the vegetative yield across all tested cultivation systems. Increases in K and S, and concentration-dependent decreases in Fe and Na content in wheatgrass were observed. Biochar influenced the reproduction of hydroponically cultivated wheat by increasing the number of spikes and the number of seeds per spike. The antioxidative capacity of wheat grass, and the seed sugar and starch contents remained unaffected by biochar application. This study contributes to innovation in soilless cultivation approaches of staple crops, within the framework of closing waste loops for a circular bioeconomy.The manuscript was published in Frontiers, Frontiers in Plant Science, Section Plant Nutrition, in a research topic called 'Application and Mechanism of Plant Biostimulants, Biochar, Fertilizer Products, and Other Nutrition-related Agrochemicals'.

The ATLAS ROBIN – A High-Performance Data-Acquisition Module
Full text linkThis work presents the re-configurable processor ROBIN, which is a key element of the data-acquisition-system of the ATLAS experiment, located at the new LHC at CERN. The ATLAS detector provides data over 1600 channels simultaneously towards the DAQ system. The ATLAS dataflow model follows the “PULL” strategy in contrast to the commonly used “PUSH” strategy. The data volume transported is reduced by a factor of 10, however the data must be temporarily stored at the entry to the DAQ system. The input layer consists of approx. 160 ROS read-out units comprising 1 PC and 4 ROBIN modules. Each ROBIN device acquires detector data via 3 input channels and performs local buffering. Board control is done via a 64-bit PCI interface. Event selection and data transmission runs via PCI in the baseline bus-based ROS. Alternatively, a local GE interface can take over part or all of the data traffic in the switch-based ROS, in order to reduce the load on the host PC. The performance of the ROBIN module stems from the close cooperation of a fast embedded processor with a complex FPGA. The efficient task-distribution lets the processor handle all complex management functionality, programmed in “C” while all movement of data is performed by the FPGA via multiple, concurrently operating DMA engines. The ROBIN-project was carried-out by and international team and comprises the design specification, the development of the ROBIN hardware, firmware (VHDL and C-Code), host-code (C++), prototyping, volume production and installation of 700 boards. The project was led by the author of this thesis. The hardware platform is an evolution of a FPGA processor previously designed by the author. He has contributed elementary concepts of the communication mechanisms and the “C”-coded embedded application software. He also organised and supervised the prototype and series productions including the various design reports and presentations. The results show that the ROBIN-module is able to meet its ambitious requirements of 100kHz incoming fragment rate per channel with a concurrent outgoing fragment rate of 21kHz per channel. At the system level, each ROS unit (12 channels) operates at the same rates, however for a subset of the channels only. The ATLAS DAQ system – with 640 ROBIN modules installed – has performed a successful data-taking phase at the start-up of the LHC in September

Round-robin tests of porous disc models
No full textNine research teams organized a round-robin measurement campaign of the wake of two porous discs in a homogeneous and "low-turbulent' flow. Mean streamwise velocity and turbulence intensity profiles at four diameters downstream of the discs were measured and compared through such metrics as the maximum of velocity deficit, the maximum of turbulence intensity, the wake width and the thrust coefficient. The dependence of these metrics on the inflow conditions (freestream turbulence intensity and Reynolds number based on the disc diameter) is discussed.Team Jan-Willem van WingerdenDesign Conceptualization and CommunicationWind Energ
ROBIN: A novel personal recommendation model based on information propagation
No full textWith the rapid development of the Internet technology, we have now entered the era of information overloading. Recommendation System technology can recommend web resources or information to people based on his/her personal preference, and has gotten a great deal of attention and development in recent years. In this paper, by combining collaborative filtering technology and information propagation principle, we proposed ROBIN, a novel recommendation model. The ROBIN model achieves a good recommendation effect by propagating the relationship information between users and resources. Based on the ROBIN model, we designed and implemented tag recommendation algorithm named ROBIN-T. For evaluating our proposed method, we have conducted tag recommendation experiments on three real datasets and the results show that the ROBIN-T algorithm achieves good performance when compared with classical approaches.
