Estimation of permeability function for concrete

Due to the construction of underground structures and hazardous waste storages, understanding and modelling of seepage in concrete has become an important issue in life-span analyses. This study deals with the estimation of unsaturated permeability function for different concrete mixtures using the theory of water retention curve. The WRC is an essential unsaturated soil function, which can be determined not only for soil samples, but also for other porous media. The theory of unsaturated soil mechanics can be applied for modelling of seepage in porous medium and for concrete as well. RÉSUMÉ: En raison de la construction de structures souterraines et de stockages de déchets dangereux, la compréhension et la modélisation des infiltrations dans le béton sont devenues un problème important dans les analyses de durée de vie. Cette étude traite de l'estimation de la fonction de perméabilité non saturée pour différents mélanges de béton en utilisant la théorie de la courbe de rétention d'eau. La courbe de rétention d'eau est une fonction essentielle du sol non saturé, qui peut être déterminée non seulement pour les échantillons de sol, mais également pour d'autres milieux poreux. La théorie de la mécanique des sols non saturés peut être appliquée à la modélisation des infiltrations en milieu poreux et au béton.
Response surface optimization of quality parameters of turmeric slices in an innovative infrared assisted hybrid solar dryer

Drying of pre-treated turmeric slices was performed in an innovative infrared assisted hybrid solar dryer. The study evaluated the effect on the drying time and quality parameters (color, antioxidant activity) of the pre-treated turmeric slices by the independent parameters. Numerical optimization of process parameters for solar drying of turmeric slices was done through response surface methodology approach with Box-Behnken experimental design. Three levels of independent parameters including dryer temperature (50 to 70oC), power of infrared (1000 to 1500 W) and drying tray to infrared source distance (11 to 35 cm) were used for the experiment. At the optimized values of dependent parameters (69.16oC, 1500 W and 11 cm), the color variation, antioxidant activity (EC50 value) and drying time was 13.684, 5.131 and 307.2 min respectively.

SOURCE-PLANE RECONSTRUCTION OF THE BRIGHT LENSED GALAXY RCSGA 032727-132609

We present new Hubble Space Telescope/Wide Field Camera 3 imaging data of RCSGA 032727-132609, a bright lensed galaxy at z = 1.7 that is magnified and stretched by the lensing cluster RCS2 032727-132623. Using this new high-resolution imaging, we modify our previous lens model (which was based on ground-based data) to fully understand the lensing geometry, and use it to reconstruct the lensed galaxy in the source plane. This giant arc represents a unique opportunity to peer into 100 pc scale structures in a high-redshift galaxy. This new source reconstruction will be crucial for a future analysis of the spatially resolved rest-UV and rest-optical spectra of the brightest parts of the arc.
High-Performance Vision-Based Navigation on SoC FPGA for Spacecraft Proximity Operations

Future autonomous spacecraft rendezvous with uncooperative or unprepared objects will be enabled by vision-based navigation, which imposes great computational challenges. Targeting short duration missions in low Earth orbit, this paper develops high-performance avionics supporting custom computer vision algorithms of increased complexity for satellite pose tracking. At algorithmic level, we track 6D pose by rendering a depth image from an object mesh model and robustly matching edges detected in the depth and intensity images. At system level, we devise an architecture to exploit the structure of commercial system-on-chip FPGAs, i.e., Zynq7000, and the benefits of tightly coupling VHDL accelerators with CPU-based functions. At implementation level, we employ our custom HW/SW co-design methodology and an elaborate combination of digital circuit design techniques to optimize and map efficiently all functions to a compact embedded device. Providing significant performance per watt improvement, the resulting VBN system achieves a throughput of 10–14 FPS for 1 Mpixel images, with only 4.3 watts mean power and 1U size, while tracking ENVISAT in real-time with only 0.5% mean positional error.
An innovative hybrid approach for detection of pacemaker pulses at low sampling frequency

Accurate assessment of pacemaker function or malfunction is essential to make clinical interpretations on pacemaker therapy and patient symptoms. This article presents an innovative approach for detecting pacemaker pulses at sampling frequency as low as 125Hz. The proposed method is validated in wide range of simulated clinical ECG conditions such as arrhythmia (sinus rhythms, supraventricular rhythms, and AV blocks), pulse amplitudes (~100µV to ~3mV), pulse durations (~100µs to ~2ms), pacemaker modes and types (fixed–rate or on–demand single chamber, dual chamber, and bi–ventricular pacing), and physiological noise (tremor). The proposed algorithm demonstrates clinically acceptable detection accuracies with sensitivity and PPV of 98.1 ± 4.4 % and 100 %, respectively. In conclusion, the approach is well suited for integration in long–term wearable ECG sensor devices operating at a low sample frequency to monitor pacemaker function.Clinical Relevance— The proposed system enables real–time long–term continuous assessment of the proper functioning of implanted pacemaker and progression of treatment for cardiac conditions using battery–powered wearable ECG monitors.
Antisickling properties, thermal and photochemical degradations of anthocyanin extracts from Annona senegalensis (Annonaceae)

Anthocyanin crude extracts and fractions of Annona senegalensis leaves were screened for their antisickling properties using a validated in vitro bioassay model of sickle cell anaemia. Preparative thin layer chromatography of acetylated anthocyanin crude extracts carried out with chloroform as solvent provided two active fractions named Ac1 and Ac2. Fraction Ac2 was quantitatively isolated and submitted to physicochemical investigations. Thermo-degradation kinetics of the above fraction Ac2 at 80 °C and 100 °C revealed first order reaction with the rate constants k (s-1) of 8.10 10-4 and 11.0 10-4, respectively. Anthocyanin crude extracts and the separated fractions showed in vitro antisickling activity. This activity justifies the use of this plant by congolese traditional healers; thus anthocyanins could be the major active principles. However, these natural pigments are unstable towards UV-vis light irradiations and heat. The conservation of this plant should then be performed in the absence of heat and/or light.

Influence Of Organizational Suport And Digital Literacy On Lecturer Acceptance Of E-Learning In Indonesia: A Modification Of Technologi Acceptance Model

: The purpose of this research is to investigate the factors that influence the lecturer acceptance of using E-learning in University. Technology Acceptance Model (TAM) as a Grounded theory and has been modified by adding another factors namely organizational support and digital literacy as the external factor. This research using Structural Equation Model (SEM) as a tool to analyses the model with number of respondent 277 lecturers in Universitas Negeri Semarang, Indonesia. The result showed that the modified TAM model with digital literacy and organizational support as external factors is appropriate for analyzing relationship among external factor, Perceived Usefulness, Perceived Ease of Use, Attitude toward using E-learning and behavioral intention E-learning. It means that the model can be used to develop the intention of using E-learning. Meanwhile the regression analysis show that the digital literacy has a significant influence to perceived usefulness and perceived ease of use. Another external factor, organization have a significant effect to perceived usefulness but insignificant to perceived easy to use. In addition, attitude toward using E-learning effectively mediates the lecturer perceived to behavioral intention E-Learning.
A Pneumatically Driven, Disposable, Soft Robotic Gripper Equipped with Retractable, Telescopic Fingers

Robots use their end-effectors to grasp and manipulate objects in unstructured and dynamic environments. Robot hands and grippers can vary from rigid and complex designs to soft, inflatable, and lightweight structures. In this paper, we focus on the development of a soft, retractable, telescopic gripper that exhibits an adaptive behaviour that allows efficient and stable grasps with a wide range of objects. The efficiency of the proposed device is experimentally validated through three different types of experiments: i) grasping experiments that involve different everyday objects, ii) force exertion experiments that capture the maximum forces that can be exerted by the proposed device, and iii) grasp resistance experiments that focus on the effect of the inflatable structure on resisting environmental uncertainties and disturbances. The proposed gripper is able to grasp a plethora of everyday life objects and it can exert more than 8 N of grasping force. The design is so low-cost that the soft fingers can be used in a disposable manner, facilitating the execution of specialized tasks (e.g., grasping in sterilized environments, handling of medical waste, etc).
A Systematic Test of the Independence Axiom Near Certainty*

We analyze the independence axiom using lotteries distributed over the entire probability simplex. We focus our analysis on questions involving certainty. This allows us to compare independence violations when certainty is preferred to risk, consistent with the well-documented “certainty effect," to those when risk is preferred to certainty, consistent with the reverse certainty effect. We find that violations of independence consistent with the reverse certainty effect are much more common than violations consistent with the certainty effect, contrary to popular belief. Results hold as we test robustness along two dimensions: varying the mixing lottery and moving slightly away from certainty.
Near-Surface Shear Flow in the Tropical Pacific Cold Tongue Front*

Abstract Near-surface shear in the Pacific cold tongue front at 2°N, 140°W was measured using a set of five moored current meters between 5 and 25 m for nine months during 2004–05. Mean near-surface currents were strongly westward and only weakly northward (∼3 cm s−1). Mean near-surface shear was primarily westward and, thus, oriented to the left of the southeasterly trades. When the southwestward geostrophic shear was subtracted from the observed shear, the residual ageostrophic currents relative to 25 m were northward and had an Ekman-like spiral, in qualitative agreement with an Ekman model modified for regions with a vertically uniform front. According to this “frontal Ekman” model, the ageostrophic Ekman spiral is forced by the portion of the wind stress that is not balanced by the surface geostrophic shear. Analysis of a composite tropical instability wave (TIW) confirms that ageostrophic shear is minimized when winds blow along the front, and strengthens when winds blow oblique to the front. Furthe.
Cerasus xueluoensis (Rosaceae), a New Species from China

Cerasus xueluoensis C.H. Nan & X.R. Wang, a new species from Hubei and Jiangxi provinces, China, is described, illustrated and compared with its congeners. It is somewhat similar to C. tomentosa and C. tianshanicae, but it is distinguished by its 2–4-flowered umbellate inflorescences, much longer pedicels (0.6–2.5 cm), a glabrous pistil and black drupes. A key to distinguish it from the other species of subgen. Microcerasus in China is provided.
Papers in Evolutionary Economic Geography

| While innovation policy started as national policy, we witness a proliferation both at the sub-national and the supra-national level. This begs the question about subsidiarity: what policies should be organized at sub-national, national and supra-national levels? We argue that innovation policies aimed to solve societal challenges such as climate change or aging – currently central in EU policies – are better organized at sub-national levels given the contested nature of problem identification and the contextual nature of problem-solving. Regional innovation policy, then, should formulate concrete societal goals relevant to the local community and tailored to the local context.
Floristics and soil relations of upland swamp vegetation near Sydney

We examined relations between vegetation and soils, using multivariate methods, in hitherto poorly-known upland swamps on the Woronora Plateau, south of Sydney. A major trend in floristic composition was related to the height and cover of the herbaceous stratum and reflected a gradient in soil moisture and nutrients. A second trend in floristic composition was related to the height and cover of the shrub stratum, and may reflect the influence of recurring fires on certain dominant shrub species. Five plant communities were recognized on the basis of floristic composition and were distinguishable by their different soil habitats and/or structural characteristics. We report some of the highest species-richness values in the world (at scales of 1–15 m2) for shrub/sedge-dominated vegetation, with up to 70 vascular plant species in 15 m2. Variation in species richness is inversely related to the resource gradient and positively related to the penetration of light through the vegetation canopy. This pattern is consistent with resource-competition models and warrants further investigation.
Electrophysiologic Insights Into SiteofAtrioventricular Block

RESULTS A total of 100 patients with advanced AVB (age 75 12 years; male 62%; AV nodal 46%; infranodal 54%) underwent permanent HBP. HBP was successful in 84 patients (84%; AV nodal 93%, infranodal 76%). Mean procedure time was 71 21 min, mean fluoroscopy time was 11 6 min. Baseline QRS duration was 122 27 ms; paced QRSd was 124 22 ms. The HB pacing threshold at implant, 2 weeks, 2 months, and last follow-up (19 12 months; range: 6 to 46 months) was 1.3 0.9 V, 1.6 1.0 V, 1.6 1.1 V, and 1.7 1.0 V at 0.5 ms, respectively. Five patients required lead revision.
A class of models for Bayesian predictive inference

In a Bayesian framework, to make predictions on a sequence X 1 , X 2 , . of random observations, the inferrer needs to assign the predictive distributions σ n ( · ) = P (cid:0) X n +1 ∈ · | X 1 , . , X n (cid:1) . In this paper, we propose to assign σ n directly, without passing through the usual prior/posterior scheme. One main advantage is that no prior probability has to be assessed. The data sequence ( X n ) is assumed to be conditionally identically distributed (c.i.d.) in the sense of [4]. To realize this programme, a class Σ of predictive distributions is introduced and investigated. Such a Σ is rich enough to model various real situations and ( X n ) is actually c.i. d. if σ n belongs to Σ. Furthermore, when a new observation X n +1 becomes available, σ n +1 can be obtained by a simple recursive update of σ n . If µ is the a.s. weak limit of σ n , conditions for µ to be a.s. discrete are provided as well
Ecological adaptations for Large-billed, Yellow-throated and White-browed Scrubwrens

Large-billed Scrubwren, Sericornis magnirostris, White-browed Scrubwren, S. frontalis, and Yellowthroated Scrubwren, S. citreogularis, inhabit the same geographical range but do not appear to compete directly with each other. This led to the following hypotheses: firstly White-browed Scrubwrens will differ from Yellow-throated Scrubwrens in the type of vegetation they forage in; and secondly Largebilled Scrubwrens will differ from both Yellow-throated and White-browed Scrubwrens in their use of different foraging heights. Observations indicated that the foraging area of White-browed Scrubwren was significantly different to that of the Yellow-throated Scrubwren in the main type of vegetation used with White-browed using the edge vegetation along the roads (mainly exotic species) and Yellow-throated using the denser rainforest vegetation. The Large-billed Scrubwren was found to forage in a different layer of the forest (foraging mainly in the mid-storey) to that of both White-browed Scrubwrens and Yellow-throated Scrubwrens (which both forage mainly in the undergrowth). It was concluded that the three species of scrubwren have evolved different foraging adaptations to avoid competing with each other in the same geographical area.
The Sirex Wood-wasps and their Importance in Forestry

(1) A complete review of the classification and status of the Siricid wood-wasps occurring in Britain is given in this paper. (2) The biology of S. cyaneus , F. , which has been studied at Tubney Wood, Oxford, during the past two years, is described, together with supplementary notes on S. gigas , L. (3) A study of the forest relations of S. cyaneus at Tubney has shown that this species cannot be considered a primary enemy of healthy green trees. Trees which are favoured by Sirex are usually markedly unhealthy from one cause or another. At Tubney unsuitable soil conditions were the principal factors. (4) Sirex and Tetropium gabrieli , Weise, the larch longicorn beetle, may occur almost simultaneously as indicators of pathological conditions in larch woods. (5) In North Devon Fomes annosus , a root fungus, was the predisposing factor in the case of silver fir attacked by Sirex . (6) Both S. cyaneus and S. gigas may occur in the same tree. This was found to be the case at South Molton, North Devon, in silver fir. S. gigas appears to prefer larger trees, and it is not present in the larch at Tubney Wood, which is in the pole stage. (7) The primary object of the work was to acquire a knowledge of the parasites of Sirex, Rhyssa persuasoria , L. , and Ibalia leucospoides , Hochenw. Both parasites were studied at Tubney, and have already been dealt with (Bull. Ent. Res. xix p. 67, 1928). (8) It is considered probable that the results obtained in the above study will throw some light on the Sirex problem in New Zealand. Emphasis is therefore laid upon the importance of studying the silvicultural conditions in relation to Sirex attack.
THE EFFECT OF CONCRETE-STEEL INTERFACE MODEL ON FINITE ELEMENT ANALYSIS OF CONCRETE FILLED SQUARE STEEL TUBE BEAM

Three-dimensional nonlinear finite element (FEA) is developed to predict the experimental behaviour of concrete filled square steel tubular member. The FEA is conducted to determine moment carrying capacity at ultimate load for simple beam. The concrete-steel interface model is the important parameter affecting the result of FEA simulation. Based on the experimental result, there is a local buckling near the loading contact point. To investigate the local buckling phenomenon, concrete-steel interface model is studied by using contact analysis between concrete and steel elements, by using rigid bar element (rbe2 element) and by using interface elements. The geometrical non-linearity, material non-linearity, loading, boundary conditions is the same for all analysis models. To account for all of these properties, FEA model by means MSC Marc Mentat software is developed. The proposed model can predict the ultimate strength with difference only 5-30%. The collapse modes by FEA model are also compared. Based on the numerical analysis, it can be seen that the local buckling is clearly shown in the FEA model with the concrete and steel interface by using interface elements.
Scaffolding Mathematics Remediation for Academically At-Risk Students Following Developmental Education Reform in Florida

ABSTRACT The purpose of this qualitative study is to understand how educational scaffolding may explain changing patterns of student success in mathematics in the era of developmental education (DE or remediation) reform in Florida College System (FCS) institutions. Specifically, we apply the concept of scaffolding to underprepared FCS students who are at risk of dropping out or failing gateway courses (the first credit-bearing college-level class in a course sequence) because they lack the academic skills necessary to succeed in college-level coursework, particularly in mathematics. We present data from focus groups conducted at 10 FCS institutions, suggesting that a reduction of scaffolding in math remediation occurred in the areas of course sequencing, instruction, and coordination with academic support services following state-level policy changes. In light of these findings, we offer a discussion of practical recommendations for college administrators related to academic advising, instructional strategies in DE courses, coordination between developmental and college-level instructors, student success courses, and the integration of DE instruction with academic support. We also suggest directions for continued research on the effects of policy changes in the FCS and DE reform efforts across the country.

Diet of the garfish belone belone l. from courtmacsherry bay ireland

Adult garfish were captured by rod and line from Courtmacsherry Bay, Co. Cork, southern Ireland. Examination of gut contents showed that they feed on crustaceans, especially crab larvae, and juvenile fish, mostly clupeids. They also take stranded insects from the sea surface. Post-larval garfish were found to be feeding on the smaller elements of the neuston, such as copepods and larval bryozoans.
