On the metaheuristic models for the prediction of cement-metakaolin mortars compressive strength

In recent years, metakaolin, as a highly reactive pozzolan, has been in the center of research concerning mortar-based materials. Metakaolin is used as an addition in cement-mortars, substituting the cement fraction to a certain extent, in order to enhance sustainability of cement mortars, both in terms of environmental impact of raw materials production, as well as in terms of improving cement-based mortars durability under environmental actions. However, as metakaolin affects the mechanical performance of cement-based mortars, it is important to know the compressive strength that these blended mortars achieve at 28-days, in terms of structural design. Toward this direction, metaheuristic models such as ANN and Genetic Programming (GP) models have been developed and trained through the use of a database, compiled by available, in the literature, experimental works related to cement and blended cement-metakaolin mortars. In the model development phase, the most important parameters affecting the strength of concrete-based mortars, were investigated and selected. In addition, the effect of the selected transfer functions, as well as the initial values of weights and biases on the performance of ANN models, were also investigated. Based on this analysis, it was shown that ANNs with selected transfer functions (such as the RadialBasis transfer function, the Soft-Max transfer function, and the Normalized Radial Basis transfer function) were, able to reliably simulate the 28-days compressive strength of the cement-based mortars. In addition, it was shown that parameters such as the cement grade and the maximum diameter of aggregates, are very important in determining compressive strength of the cement-based mortars; this is an important finding, because these parameters are usually not taken into account in the research studies concerned in the prediction of compressive strength through computational models.
Dietary soybean lecithin affects growth performance, fillet biochemical composition and digestive enzyme activity in Sparidentex hasta juvenile

ABSTRACT An eight-week study was conducted on silvery-black porgy (Sparidentex hasta) juveniles to evaluate four isoproteic, isolipidic and isoenergetic different diets (50% crude protein, 20% crude lipids, 18.5 MJ kg−1) containing graded levels of soybean lecithin (SBL) (0, 30, 60 and 90 g kg−1 diet) at the expense of fish oil (FO). Fish fed the 60 g SBL kg−1 diet had significantly higher weight gain (32.4%) and feed intake (8.8 g fish−1) than the control group (SBL 0) (P < 0.05). The fillet fatty acid (FA) profiles were correlated with the FA profile of the experimental diets. Fish fed with SBL-supplemented diets had higher fillet phosphatidylcholine levels than the control group (P < 0.05). Plasma total immunoglobulin was higher in fish fed 60 and 90 g SBL kg−1 diets than in the other groups (P < 0.05). Total protease activity was higher in fish fed the 90 g SLB kg−1 diet than other treatments (P < 0.05). Results indicated that substitution of dietary FO with SBL diet up to 67% (60 g SLB kg−1 diet) improved somatic growth performance and profoundly affected the fillet fatty acid profile in silvery-black porgy juveniles.
Data Sharing by Enabling authentication and Access control with Credential Information Hiding

: To improve the quality of healthcare and individual’s quality of life E-healthcare cloud system shown its potential unluckily, privacy and security slow down its general deployment and application there are many researches focusing on preserving the privacy of the electronic healthcare record (EHR) data. However, these works have two main limitations first, they only works on ‘black or white’ access control policy. Second, they suffer from the inference attack. This paper, for the first time, we design an inference attack-resistant E-healthcare cloud system with fine-grained access control we first propose a two-layer encryption scheme. To make sure an efficient and fine-grained access control over the EHR data, we design the first-layer encryption, where we develop a specialized access policy for each data attribute in the EHR, and encrypt them individually with high efficiency. To preserve the privacy of role attributes and access policies used in the first-layer encryption, we systematically build the second-layer encryption To take full benefit of the cloud server, we propose to let the cloud execute computationally concentrated works on behalf of the data user without knowing any sensitive information To preserve the access pattern of data attributes in the EHR, we additional construct a blind data retrieving protocol. We also show that our scheme can be easily extended to support search functionality. Finally, we conduct extensive security analyses and performance evaluations.
A Collaborative Way of Knowing: Bridging Computational Communication Research and Grounded Theory Ethnography

One of the great strengths of the field of communication is its interdisciplinarity. Yet this strength brings challenges, including rifts between diverse subfields. In this study, we illustrate the rich potential of collaborations across subfields. Specifically, we argue that due to often-overlooked epistemological similarities, unsupervised machine learning and grounded theory ethnography subfields are well-suited for an especially enriching collaboration. To demonstrate, a team of computational and ethnographic researchers together applied the analysis of topic model networks approach to ethnographic field notes. We illustrate how the inclusion of the ethnographer in the modeling stages, and of the computational researchers in the analysis stages, led to mutual reflexivity affecting every stage of the study, enabling profound reflections on the technical, conceptual, and theoretical pillars of both subfields. We conclude by discussing the potential future of such collaborative ways of knowing to open doors for cutting-edge interdisciplinary research for the new information era.
Dietary preference and feeding patterns of the urban Rhesus Macaque Macaca mulatta (Mammalia: Primates: Cercopithecidae) in Asola-Bhatti Wildlife Sanctuary in India

We studied the feeding patterns and discrete spatio-temporal food habitsof16 groups of the urban Rhesus Macaque Macaca mulatta following their relocation in Asola-Bhatti Wildlife Sanctuary near Delhi, India. We observed that the macaques fed on 31 plant species, with Prosopis juliflora and P. cineraria appearing in most scans. We classified the food consumed by the species into six main categories the species and recorded the average time spent on each of these throughout the year. The maximum time was spent on supplementary feeding provided by the forest department and the minimum on natural plant resources. There was a significant difference in the consumption of different food categories from morning to evening but there were no significant seasonal variations. This study showed that Rhesus Macaque adopted different foraging strategies based on the availability of resources in their new environment and that variety in food resources buffered seasonality in their diet. Information on their feeding patterns and food habits will help in developing management protocols for the primates in urban environments.
Inter-individual genomic heterogeneity within European population isolates

A number of studies carried out since the early ‘70s has investigated the effects of isolation on genetic variation within and among human populations in diverse geographical contexts. However, no extensive analysis has been carried out on the heterogeneity among genomes within isolated populations. This issue is worth exploring since events of recent admixture and/or subdivision could potentially disrupt the genetic homogeneity which is to be expected when isolation is prolonged and constant over time. Here, we analyze literature data relative to 87,818 autosomal single-nucleotide polymorphisms, which were obtained from a total of 28 European populations. Our results challenge the traditional paradigm of population isolates as genetically (and genomically) uniform entities. In fact, focusing on the distribution of variance of intra-population diversity measures across individuals, we show that the inter-individual heterogeneity of isolated populations is at least comparable to the open ones. More in particular, three small and highly inbred isolates (Sappada, Sauris and Timau in Northeastern Italy) were found to be characterized by levels of this parameter largely exceeding that of all other populations, possibly due to relatively recent events of genetic introgression. Finally, we propose a way to monitor the effects of inter-individual heterogeneity in disease-gene association studies.

Expériences d interférométrie atomique avec l'atome de lithium

Cette etude presente la mise au point d'un interferometre atomique de Mach Zehnder et son utilisation pour des mesures interferometriques. Un jet supersonique de lithium est diffracte elastiquement dans le regime de Bragg par des ondes laser stationnaires quasi-resonnantes avec la premiere transition de resonance du lithium a 671 nm. Une modelisation de l'interferometre est realisee grâce a une simulation numerique du processus de diffraction, ce qui permet de decrire precisement le caractere selectif de l'interferometre en vitesse et en angle d'incidence. Les signaux d'interferences obtenus presentent, au premier ordre de diffraction, une visibilite allant jusqu'a 84. 5%. Aux deuxieme et troisieme ordres de diffraction, la visibilite des signaux observes est reduite et cette reduction est largement due au bruit de phase induit par les vibrations mecaniques de l'interferometre. La qualite des signaux au premier ordre de diffraction est utilisee pour realiser deux mesures interferometriques. L'application d'un champ electrique sur un seul des deux faisceaux atomiques, separes de 90 microns, induit un dephasage du signal d'interference dont la mesure permet de determiner tres precisement la polarisabilite de l'atome de lithium, alpha = (24. 34 ± 0. 16) 10-30 m3, en excellent accord avec les calculs les plus precis. De meme, en interposant du gaz sur un seul faisceau atomique, on realise une serie de mesures de l'indice de refraction n de gaz (Ar, Kr, Xe) pour une onde atomique de lithium. La linearite de (n-1) en fonction de la densite de gaz est bien verifiee. En faisant varier la longueur d'onde du lithium, j'ai observe les oscillations de gloire des parties reelle et imaginaire de l'indice de refraction ainsi que de leur rapport rho. Ces mesures sont comparees a des mesures de section efficace totale pour la partie imaginaire de l'indice et a des calculs pour la partie reelle et le rapport rho. Dans tous les cas, la comparaison est tres satisfaisante.
Methodology for selection and decision making of gradation of sleepiness using algorithms for face video image processing

The complexity of the problem to evaluate the human functional state and fatigue can be divided into the research of pathological and physiological forms of fatigue where current research is focused on the physiological form and characterized as proportional to the activity and acute as the functional state can be recovered by sleep and rest. Sleepiness or drowsiness is among the key indications of physiological fatigue and persists throughout the human daily cycle. The risks often associated with a certain gradation of sleepiness, classification of which is described in this article are mainly considered in the context of determining the degree of sleepiness of the driver or operation safety in the workplace. The main methods to be addressed in this paper are the selection of a set of sleepiness characteristics to determine the degree of sleepiness, the selection of the most informative traits for decision-making algorithms, and the resolution of problems associated with visual information extraction from the video. A methodology with multiple algorithms is proposed to obtain values for sleepiness characteristics from a video with human face regions. A total of 28 characteristics were obtained. The decision-making algorithms were trained by using a video database that provided sleep values for the existing video and validated with volunteer video dataset. The classification space three degrees of sleepiness was applied to label the videos, and two classes where low levels of alertness and severe sleepiness were combined into one class. For the prediction of the three degrees of sleepiness, the accuracy of decision algorithms ranged from 37 % to 53 %, which in all cases was better than the free guess limit of 33 %. For the prediction of two levels of sleepiness, the accuracy of decision algorithms ranged from 67 % to 73 %, which in all cases was better than the 50 % limit of free guess.
Evaluation of forage quantity and quality in the semi-arid Borana Lowlands, Southern Oromia, Ethiopia

This study was conducted with the aim of determining herbaceous biomass during different seasons, plus nutritive value of herbaceous species and forage on selected woody plants and documenting pastoralists’ perceptions of the value of various forage species in Borana Zone, Oromia, Ethiopia. Data were collected from a total of 92 main plots of 500 m2 during rainy and dry seasons located across different functional Land Use Units called Kalo (enclosed areas), Worra (grazed by lactating stock) and Foora (more remote and grazed by dry and non-lactating stock). Total herbage and leaves of woody plants were analyzed for concentrations of crude protein (CP), organic matter (OM), neutral detergent fiber (NDF), acid detergent fiber (ADF), acid detergent lignin (ADL) and ash. Perceptions of farmers were determined through group discussions. Herbage biomass plus chemical composition of both herbaceous and woody forage species varied significantly across seasons and Land Use Units. Mean herbaceous biomass in all Land Use Units was poor (876‒1,469 kg DM/ha). Mean CP, NDF and ADF concentrations of the herbaceous samples were 62, 749 and 444 g/kg DM, respectively. Mean CP% of leaves from woody plants was higher (11%) than from herbage (6%). In both groups, crude protein concentrations were highest during the wet season and lowest during the dry season, whereas fiber concentrations were highest in the dry season. Mean CP% of herbaceous forage species was below the critical level recommended for both beef cattle (7%) and small ruminants (9%) but forage from woody species should provide a reliable supply of supplementary nitrogen. Management of rangelands should be designed to ensure that desirable herbaceous species are preserved, while desirable woody species are also a valuable asset. Determination of management strategies to ensure that the desirable mix of species is maintained is imperative if sustainable production is to continue.
Viability and vigour loss during storage of Rudbeckia mollis seeds having different mass: an intra-specific perspective

Abstract Recent evidence points to relationships between intra-specific seed mass variation and viability loss in response to ageing stress. However, little is known about how seed quality may change temporally in response to such stress. Here we examined seed–water relations of mass-separated Rudbeckia mollis seeds to better understand physiological status among mass classes. We then evaluated seed viability and vigour changes in response to various storage conditions or post-storage vigour tests (a 41°C, 75% RH stress for up to 45 d). We found similar pre-storage physiology among mass classes. However, seeds of lower mass deteriorated up to 1.5-fold faster than heavier seeds under certain conditions. Stressing seeds after storage resulted in distinct vigour differences among mass classes. For example, vigour in lower mass seeds tended to decline more compared to heavier seeds following storage in a climate-controlled room. Alternatively, vigour loss varied among mass classes following storage in a non-climate-controlled shed. Our results highlight the importance of distinguishing between pre-sowing storage and post-storage vigour effects when quantifying relative levels of viability loss among seeds of different mass. Furthermore, differential responses to storage and ageing stress among mass classes may have important implications for post-storage regeneration and subsequent population dynamics.
First Report of Chrysodeixis includens Nucleopolyhedrovirus (ChinNPV) Infecting Chrysodeixis includens (Lepidoptera: Noctuidae) in Argentina

Summary Typical baculovirus infection symptoms were observed in Chrysodeixis includens Walker (Lepidoptera: Noctuidae) larvae from a laboratory rearing in Tucumán, Argentina. Scanning electron microscopy revealed the occurrence of polyhedral occlusion bodies displaying a heterogeneous morphology. Amplification, sequencing, and phylogenetic analysis of conserved polyhedrin, lef-8 and lef-9 genes identified the pathogen, for the first time in Argentina, as a variant of Chrysodeixis includens nucleopolyhedrovirus (ChinNPV). The biocontrol potential of this new isolate is worthy of future research.
Thermal Neutron Scattering Measurements of YHx for the Transformational Challenge Reactor

The Transformational Challenge Reactor (TCR) targets application of advances in manufacturing, materials, and computational sciences to accelerate development of new nuclear reactor technologies as well as their adoption by the U.S. industry [1]. The TCR leverages advanced manufacturing capabilities at Oak Ridge National Laboratory (ORNL) to facilitate an agile reactor design with the ability to take advantage of advanced materials and data science-informed certification schemes. Since TCR is gas-cooled a thermal reactor, the choice of neutron moderating material is of crucial importance. To achieve a highly efficient and compact core while minimizing the amount of high assay low enriched uranium required [2], a hydrogen-bearing moderator that is stable to high temperatures is required. This initially led to the selection of metal hydrides (i.e., ZrHx and YHx) for the TCR demonstration core. ZrHx has been extensively studied and used in previous reactor designs since the 1950s due to its low absorption cross section and general availability [3]. However, during the same period, the unavailability of high-purity yttrium as an industrial metal barred it from being considered as another candidate although it exhibits advantageous thermal stability compared to ZrHx [4, 5]. Today yttrium metal of high purity is available as an industrial metal and therefore, YHx was chosen as the moderator material for the TCR. However, a complete thermal scattering library is currently lacking and is needed for an accurate representation of TCR core neutronics properties. This paper details the first step towards the evaluation of a YHx thermal scattering library through the conduct of thermal neutron scattering experiments for various hydrogen atomic concentrations x = 1.62, 1.74, 1.85, 1.90 at 5 Kelvin and room temperature at the Spallation Neutron Source (SNS) at ORNL. This information supplies the necessary data for TCR’s YHx moderator while providing basic information that is necessary for design and deployment of any other reactor taking advantage of this high performance moderator.
Studies on genetic diversity of Chinese mitten crab Eriocheir sinensis of Yangtze River system based on mitochondrial DNA control region

We obtained mtDNA control region sequences of 102 E. sinensis individuals of 7 populations in Yangtze River system (Adults of E. sinensis in Huangmai, Poyang lake, Pengze, Anqing, Zhenjiang and the Yangtze estuary, juveniles of E. sinensis in Zhenjiang and the Yangtze estuary, abbreviated as HM, PY, PP, AQ, ZC, ZY and CY) and analysed their genetic diversity. The resulted showed that the complete sequences of control region was 515 bp. Total of 65 variation sites including 31 singleton polymorphic sites and 34 parsimony informative polymorphic sites were defined in the 102 individuals sampled of 7 populations, in which 60 haplotypes were detected. The haplotype diversity (Hd) was found to be 0.919±0.023, nucleotide diversity 0.01007±0.00081, the average nucleotide difference (K) 5.106. Genetic differentiation index (Fst) among populations was -0.0098 to 0.0983; genetic distance was 0.0067 to 0.0122; the genetic variation among populations accounts for only 3.3% of total variation. Mismatch distributions suggested that E. sinensis in the Yangtze River system had not experienced a rapid population expansion in the recent past. The results showed that genetic diversity level of E. sinensis in the Yangtze River system was high. The seven populations had not been formed geographic differentiation obviously and apomixes would occur between them.
Differentiation between TPACK level in junior and senior pre-service teacher to design science lesson

Technological development provides enormous opportunities for efficient and active learning. Advance in technology-based learning should be inline with the ability of teachers to teach science using technology. Preservice teachers should be equipped with an appropriate college curriculum. TPACK can be used to see the abilities of prospective science teachers. This study was examining different TPACK levels at junior and senior-level. This study involved a sample of students majoring in a bachelor's degree in science teacher program. The results of the questionnaire showed that junior-level students have higher TPACK than senior-level. Based on the results of a lesson plan analysis, junior-level students tend to use technology in the classroom. Students at the senior-level have been experienced in classroom teaching. However, classroom management and time management skills of maybe affects the TPACK level in junior and senior-level students.
