Simulation of the shielding properties of environmental components against the external radioactive radiation from the Ordovician Dictyonema shale

This paper presents the results of simulating the conditions of absorption of natural radionuclides (uranium-238, thorium-232, potassium-40) in different environment media (water and quartz sand) to assess the effect of the shielding properties of environmental components on the intensity of external radiation exposure to the benthic biota. The source of radiation was the lower Tremadocian Dictyonema shale, which formed the bottom of the Baltic Paleobasin. Water and quartz sand, which was gradually deposited on the roof of the Dictyonema shale, were used in the simulation as media (materials) absorbing the primary radiation. The manuscript shows an experiment conducted in full-scale conditions considering a single exposure of a section of Ordovician rocks that includes highly radioactive Dictyonema shale. This is a small area, but the simulation results are also valid for larger areas as the Baltic Paleobasin. During the late Tremadocian — Floian, along with transgression, benthic biota began to emerge. The experiment shows quantitatively what dosage this biota could have experienced over tens and hundreds of thousands of years, until the Dictyonema shale was covered with a sufficiently thick layer of water-flooded sediments. Experimental data show that the presence of a 10 cm thick layer of water reaches absorption of 40 % of the integral flux of all gamma lines of natural radionuclides (NRN), and in a moist quartz sand layer of the same thickness the absorption value does not exceed 50 %. Thus, despite the screening effect of the environment, the benthic biota of Baltoscandia in the Early Ordovician could have been under significant radiation exposure for millennia. The main value of the experiment is that it was performed in situ, and exclusively natural media were used as modelling elements.
Morphological Diversity of Ascobolus and Pilobolus Fungi from Wild Herbivore Dung in Nairobi National Park, Kenya

The present study examined two genera of coprophilous fungi: Ascobolus and Pilobolus with the aim of species description using their morphological diversity. Fresh dung samples from wild herbivores were collected in different parts of Nairobi National Park in Kenya and immediately taken to the laboratory for culture by moist chamber method. Isolates studied were obtained from dung of the following animals: white rhino, zebra, waterbuck, impala, Cape buffalo, giraffe, Thomson’s gazelle, dikdik, hare, grant’s hartebeest, hippopotamus and eland. Five species of Ascobolus were studied namely: Ascobolus amoenus, A. bistisii, A. calesco and A. immersus. A possible novel 4-spored Ascobolus species was observed. Three species of Pilobolus were found: Pilobolus crystallinus var. crystallinus, P. heterosporus and P. pullus. The most abundant species were: Ascobolus immersus and Pilobolus crystallinus var. crystallinus while the highest diversity was observed in waterbuck dung samples with a total of five different species.
Monte-Carlo Simulation Study of Two-Stage Quantile Regression for Dynamic Panel Data

The issue of obtaining biased estimators gradually appears when dynamic panel data (DPD) models are principally estimated by quantile regression (QR) due to the addition of lagged value(s) for dependent variable in DPD models as independent variable(s). A new approach for minimizing the bias is theoretically presented through the method of estimation of two-stage quantile regression for dynamic panel data (TSQRDPD). This proposed framework of TSQRDPD is mainly based on estimating the two stages by QR at a pre-determined rank of quantile. Moreover, bias behavior is studies through a montecarlo simulation under several quantile ranks for stages, probability distributions and panels’ dimensions. Monte-Carlo simulation results reveal that the new method of estimation is able to reduce estimators’ biasedness considerably.
Self-managing team effectiveness within the technical service sector: the influence of team structure, leadership and group processes

The aim of this exploratory study was to investigate the effectiveness of self-managing teams within the technical service sector. Although substantial research has been conducted about what is needed for the effectiveness of self-managing teams, surprisingly little research has been conducted about the effectiveness of self-managing teams within this sector and in particular self-managing teams with team member diversity concerning knowledge and skills and a high degree of interdependency. Most studies were conducted in the health-care sector, banking sector, manufacturing sector, and service companies in insurance and telecommunications. This study investigated three important conditions for effectiveness of self-managing teams: team structure, leadership and group processes. This study was an exploratory, embedded single-case study which investigated one company, and three subsidiaries of it. It used semi-structured interviews as the main data collection method. In total, 12 interviews have been conducted with team members of self-managing teams. Within the interviews the critical incident technique has been used, and two daily processes were discussed: the quotation and the assignment process. Results showed that self-managing teams in this sector with a team composition that has team members with diversity in knowledge and skills and a high degree of interdependency, have a lot in common with self-managing teams in other sectors. Nevertheless, this study did reveal some interesting findings. Results show that self-managing teams in the technical service sector indeed are diverse in highly-specialized knowledge and skills, while also being interdependent upon one another in order to successfully serve the customer. This diversity and interdependence led to two different situations: team members shifting between teams and regular collaboration with third parties. Also, the type of contract with the customer and its complexity appeared to influence the team structure of these self-managing teams. Based on these findings, practical recommendations and recommendations for future research have been established.
Compressive Sensing in Medical Image Compression

–For medical images storage and transmission, compression methods have a significant role due to the medical images large size along with the importance to save the fine details. In traditional lossy compression techniques, a lot of important details may be lost. However, the compressed sensing (CS) helps to transmit the images fast with saving their details.In the present work, different CS methods were studies to improve the images’ recovery and Quality of service (QOS). Aweighted based CS was proposed using threshold weighting matrixfrom the discrete cosine transform of the medical image using convex optimization algorithm and compare it with traditional CVX and other two types of greedy algorithms.
Design of Intelligent PID Controller using Particle Swarm Optimization with Different Performance Indices

— PID control scheme is still providing simple and effective solutions to the many control engineering problems. Today many real world problems are nonlinear and time varying, control of such problems are very difficult with the conventional designed PID controller. This paper presents a new designing technique of PID controller, which can effectively control the nonlinear optimization problems. The technique which has been introduced in this research is particle swarm optimization. It is population based stochastic optimization algorithm derived from human behavior and animal behavior as well. Conventional gain tuning schemes such as Ziegler Nichols method usually produces big overshoot therefore modern approach has been used in this paper to tune the parameters of PID controller. For designing of PID controller different performance indices have been used here for different plant transfer functions.
Phenotypic and genetic trends for peak yield, milk yield, and lactation persistency in the Murciano-Granadina breed

This study evaluated the genetic (TG) and phenotypic (TF) trends for the peak yield (PP), milk yield (RL), and lactation persistency (P) traits of the Murciano-Granadina (MG) goat lactation curve obtained from 80,872 lactations of 85,404 goats (historical records from 1990-2012). The biomodelling of lactation curves allowed us to estimate the PP, RL, and P traits using the Spline model in the “R” software. The genetic values (VGs) were obtained using the univariate animal model with repeated observations, employing the Rev Mex Cienc Pecu 2020;11(2):380-392 381 MTDFREML package. The TG and TF were estimated via the least-squares regression of the average of VGs and known yield information according to the year of birth. While calculating the TG and TF, linear regression coefficients (b) were obtained, where the b values for PP, RL, and P were +0.00071, +0.00698; +0.00114, +0.01117; and +0.00002, -0.00076, respectively. The TG and TF for the PP and RL behaved similarly following an upward trend line with increasing and decreasing intervals. The TG for P showed seasonal variations while the TF followed a downward trend with more consistent points in its trajectory; supporting the idea that high yields are detrimental to the P. These results inform the breeders about the behavior of these traits and provide the basis for the incorporation of the lactation persistency as a selection criteria in the genetic program of the MG breed.
Crossing Disciplinary Boundaries to Improve Technology-Rich Learning Environments

Background The capacity of instructional technologies to personalize instruction has progressively improved over the last decade, in conjunction with changes in learning theories that dictate what, when, and how to support learners. Focus of Study This paper reviews several technology-rich learning environments that are investigated by members of the Learning Environments Across Disciplines partnership, including Newton's Playground, the War of 1812 iHistory tours, Crystal Island, BioWorld, and MetaTutor. The adaptive capabilities of these systems are discussed in terms of the metaphors of using computers as cognitive, metacognitive, and affective tools. Research Design Researchers rely on convergent methodologies to collect data via multiple modalities to gain a better understanding of what learners know, feel, and understand. The design guidelines of these learning environments are used to situate this understanding as a means to generalize best practices in personalizing instruction. Conclusions The findings of these investigations have significant implications for the metaphor of using technology as a tool to augment our thinking. The challenge is now to broaden learning theories while taking into consideration the social and emotional perspective of learning, as well as to leverage recent advances in learning analytics and data-mining techniques to iteratively improve the design of technology-rich learning environments.
The Intersubjective Type of Religiosity: Theoretical Framework and Methodological Construction for Developing Human Sciences in a Progressive Muslim Perspective

An everlasting and perpetual peace in the life of different religious adherents anywhere is the prime purpose of human beings. This article will discuss the methods and approaches of religious education in a contemporary multicultural society. Three approaches to the study of religion: dogmatic, critical, and ethical will be elaborated simultaneously. One cannot rely solely on one approach and neglects the two others without having their implications and consequences in the life of multi-religious society. In addition to the religious and Islamic studies perspectives, I will elaborate the issues based on philosophical concepts, i.e. subjective, objective, and intersubjective, as well. The subjective perspective is commonly based on ‘ulūm al-din, meanwhile the objective one is on social sciences. The combination between the two is called, in this paper, as an intersubjective pattern of religiosity. One of its distinctive features is its sensitivity towards and its ability to accommodate the presence of other communities whose rights are respected and guaranteed. [Kedamaian yang kekal dan abadi bagi semua pemeluk agama yang berbeda di berbagai aspek kehidupannya merupakan tujuan utama dari kemanusiaan. Artikel ini membahas beberapa metode dan pendekatan pendidikan agama pada masyarakat multikultural dewasa ini. Tiga pendekatan dalam pengkajian agama yang dogmatis, kritis dan etis akan dielaborasi secara simultan. Satu pendekatan tidak bisa berdiri sendiri dan menegasikan dua yang lain karena implikasinya dalam kehidupan masyarakat yang multireligius. Selain dalam perspektif keagamaan dan keislaman, artikel ini akan mengelaborasi persoalan di atas dengan pendekatan filosofis: subjektif, objektif, dan intersubjektif. Pendekatan subjektif umumnya didasarkan pada ulūm ad-dīn, sedangkan pendekatan objektif didasarkan pada ilmu-ilmu sosial. Perpaduan antara keduanya, dalam artikel ini, disebut dengan pola keagamaan yang intersubjektif. Salah satu kekhasan pola yang disebut terakhir ini adalah sensitifitasnya terhadap kehadiran kelompok lain dan kemampuannya mengakomodasi kelompok lain tersebut sebagai pemegang hak-hak yang harus pula dijamin dan dihormati. ]
Antimicrobial Activity and Antiadherent Effect of Peruvian Psidium guajava (Guava) Leaves on a Cariogenic Biofilm Model.

AIM Phytomedicine has been commonly practiced as a form of traditional medicine in various cultures for the treatment of oral diseases. Recently, it has gained importance as an alternative to conventional treatment. Several extracts of plants and fruits have been recently evaluated for their potential activity against microorganisms involved in the development of dental caries. The purpose of this study was to evaluate the antimicrobial activity and antiadherent effect of the crude organic extract (COE) and three partitions (aqueous, butanolic, and chloroformic) of Psidium guajava (guava) leaves on a cariogenic biofilm model. MATERIALS AND METHODS Guava leaves were obtained from the mountains of northern Peru, where they grow wild and free of pesticides. The antimicrobial activity of the COEs and partitions against Streptococcus mutans and Streptococcus gordonii was determined by measuring the inhibition halos, while the effect on biofilm adhesion was determined by measuring the optical density using spectrophotometry. RESULTS An antibacterial effect of the COE and chloroformic partition against S. gordonii (p < 0.05) was found, as was a significant effect on biofilm adherence, with a minimum inhibitory concentration (MIC) of 0.78 mg/mL, which was maintained throughout the 7 days of evaluation. CONCLUSION We conclude that the COEs and their chloroformic partition have antimicrobial and antibiotic effects against this strain of S. gordonii, making them of particular interest for evaluation as a promising alternative for the prevention of dental caries. CLINICAL SIGNIFICANCE By knowing the antimicrobial effect of Psidium guajava, this substance can be effectively used in products aimed to prevent dental caries and periodontal disease.
The discursive polyphony on the 1994 World Cup: authorized discourses on the tetra championship

This article discusses the academic and journalistic production about the 1994 Soccer World Cup. Basing on the notion of authorized speeches, developed by Guedes (2010/2011) and inspired by Bourdieu (1983), we study the discourse constructed about this event on eight encyclopedias and books about World Cups, Jornal do Brasil (JB) newspaper and the special commemorative editions of Época and Placar magazines. The academic production analyzed was collected from the annals of conferences, articles published on academic journals and chapters of books. We observed that the authorized discourse lacks reflection and is led by common sense while the academic discourse lacks variety of themes, theoretical references and authors. The academic works dealt mainly on the hermeneutics of defeat, the question of national identity, the advertising and the presence of radio.
Health, Ageing and Entropy

We are usually nervous to hear about ageing. But what is it ageing? It is the accumulation of changes in an object, organism or community [1]. Ageing in humans refers to a multidimensional process of physical, psychological and social change. The contribution is a short survey which presents new knowledge coming out from research of common features among physics, biology and medicine.
Compatibility of Diborane and Borane with FOX-7 - A DFT Treatment

FOX-7 as an energetic material is getting more and more popular as the constituents of various ammunitions. On the other hand, boronic species attract attention as fuels in rocket engineering.

Optimal Approximation for Multidimensional Nonlinear Point Data Sets

The mathematical modelling of complex physical processes (objects) is based on the approximation of their experimental output variables (point data sets). It is well known that the respective mathematical models are multidimensional and significantly nonlinear, thus various mathematical methods were developed to approximate the experimental point data, each having its own inherent approximation advantages and disadvantages. However, these methods did not take into account the data structural and parametric characteristics. and thus motivated this research to develop a more universal approximation methodology to this kind of problem. The applied approximation method, named Cut-Glue Approximation, takes into account any data order and/or any nonlinear dependency based on 3 principles: fragmentation of the initial data approximated by known methods; highprecision analytical approximation of local fragments; multiplicative analytic fragmentation of local functions isolated in the factor space. This paper considers the second stage of the Cut-Glue Approximation analytical approximation of local fragments. The direct advantage of this approximation is the resulting mathematical model differentiability, which enables their analytical investigation, appropriate for modelling complex dynamical systems. Keywords-experimental data; fragments; math modeling; approximation; error; evolutionary-genetic algorithm; optimization; heuristic algorithms
Journeys within the Leucophoropterini: Revision of the Tribe, Genera and Species, and Description of New Genera and Species from Australia and the Indo-Pacific

Journeys within the Leucophoropterini: Revision of the Tribe, Genera and Species, and Description of New Genera and Species from Australia and the Indo-Pacific. (May 2011) Katrina Louise Menard, B.S., The College of William and Mary; M.S., Texas A&M University Chair of Advisory Committee: Dr. James Woolley The tribe Leucophoropterini (Miridae: Phylinae) is a diverse assemblage of primarily Indo-Pacific and Australian bugs which are united by simple, small genitalia and a trend towards ant-mimetic body forms. Previous to this work, the relationship of the Leucophoropterini to the other tribes of Phylinae, as well as the generic relationships within the lineage, was unresolved. Further, the characters initially proposed to unite the tribe are brought into question with the addition of several recently discovered taxa from Australia. The Leucophoropterini is first re-evaluated within a phylogenetic analysis of the subfamily Phylinae, using a combined molecular and morphological dataset to test the monophyly of the lineage, re-test the character synapomorphies supporting it, and to determine the closest relatives to the tribe. The molecular dataset includes 4 genes (COII, 16S, 28S, and 18S), and 123 morphological characters for 104 taxa, which is analyzed in a parsimony analysis using Tree analysis using New Technology [TNT], a
Distribution patterns in major pteridophyte taxa relative to those of angiosperms

Whereas the distribution of the principal pteridophyte families over the major parts of the globe is quite similar to that of the principal angiosperm families, pteridophyte genera are in general considerably more widespread. Four possible explanations are discussed: greater age of fern genera and thus a longer period available for dispersal; slower evolution of ferns; greater dispersability through small size of diaspores; and non-equivalence of fern and angiosperm genera. Furthermore, primitive fern genera diverge in their distribution patterns from those of primitive angiosperms; they tend to occupy special habitats and/or to possess special growth forms, rather than being concentrated in geographical relict areas, as are angiosperms. Finally, the 'American Paradox' in the distribution of fern genera and sections, which is an imbalance between the Old and the New World, is briefly
