Publisher: name: Zenodo
Year: 2017
Subjects: Biodegradation

description: One of the biggest environmental problems today is hydrocarbon pollution resulting from the activities related to the petrochemical industry. Mechanical and chemical methods that are commonly used to remove hydrocarbons from contaminated sites in terms of influence are limited and costly.Bioremediation technology is the promising for the the treatment of hydrocarbon contaminants. Bioremediation works basically on biodegradation that results conversion of complex organic contaminants to other simpler organic compounds by biological agents like microorganisms. Different factors affect the biodegradation of petroleum hydrocarbons .Among physical factors, Temperature has a direct impact on the chemical structure of pollutants so plays an important role in the biodegradation of hydrocarbons.This article presents an updated overview of microbial degradation of petroleum hydrocarbons by microorganisms in different ecosystems.
On the problem of hidden variables for quantum field theory

Subjects: subject: High Energy Physics - Theory (hep-th)

description: We show that QFT (as well as QM) is not a complete physical theory. We constructed a classical statistical model inducing quantum field averages. The phase space consists of square integrable functions, $f(ϕ),$ of the classical bosonic field, $ϕ(x).$ We call our model prequantum classical statistical field-functional theory -- PCSFFT. The correspondence between classical averages given by PCSFFT and quantum field averages given by QFT is asymptotic. The QFT-average gives the main term in the expansion of the PCSFFT-average with respect to the small parameter $α$ -- dispersion of fluctuations of "vacuum field functionals.'' The Scrödinger equation of QFT is obtained as the Hamilton equation for functionals, $F(f),$ of classical field functions, $f(ϕ).$ The main experimental prediction of PCSFFT is that QFT gives only approximative statistical predictions that might be violated in future experiments.

description: The topic of this thesis is, which is composed of four chapters, is the relation between bi- /multilingualism and dyslexia. In the theoretical framework (literature review), bi- /multilingualism, dyslexia ( categories, causes, effects) and the combination of these two are being analyzed. In the main part of the thesis forty studies – articles, book chapters, theses and conference proceedings- are being presented. The language categories are being analyzed (transparent, opaque, alphabetic, logographic) in combination with the disorder of dyslexia in bilinguals and multilinguals in the first (L1), second (L2) or third language. The topics of these studies are the interventions that are suggested when dealing with dyslexia in multilingual populations, the ideas for proper tests in order τοdetect dyslexia among bi- [6] /multilinguals and the problems that the vague definition of dyslexia among the countries is causing. The results of these studies could become the basis of future studies on this topic

description: Modelling river physical processes is of critical importance for flood protection, river management and restoration of riverine environments. Developments in algorithms and computational power have led to a wider spread of river simulation tools. However, the use of two-dimensional models can still be hindered by complexity in the setup and the high computational costs. Here we present the freeware BASEMENT version 3, a flexible tool for two-dimensional river simulations that bundles solvers for hydrodynamic, morphodynamic and scalar advection-diffusion processes. BASEMENT leverages different computational platforms (multi-core CPUs and graphics processing units GPUs) to enable the simulation of large domains and long-term river processes. The adoption of a fully costless worflow and a light GUI facilitate its broad utilization. We test its robustness and efficiency in a selection of benchmarks. Results confirm that BASEMENT could be an efficient and versatile tool for research, engineering practice and education in river modelling.

description: Anthropic principles were grown from the problem of fine tuning. Although anthropic principles have been discussed in cosmology for years there is no exact definition for fine tuning. Starting from the supposed similarity in the topologies of chaotic and fine tuned regions of the proper phase spaces, we introduce an alternative Lyapunov indicator for the measure of fine tuning. This fine-tuning indicator expresses the decrease of life-bearing potentiality of a universe with the increase of the difference from the physical constants of the universe with maximum life-bearing potentiality.

description: In the recent years, a rapid increase in population movement has been observed which, in turn, has led to the formation of classrooms that include students from various linguistic backgrounds. A significant number of these students find difficulties in handling the demands of school curriculum, while teachers tend to attribute these students’ academic underperformance to learning disabilities, thus guiding them to structures of special education. The subject of this thesis is the thorough study of the relationship between child bilingualism and learning disabilities, and, in particular, the study of the Specific Reading Disorder of bilingual students. This relationship with be studied through a review covering the years between from 2000 to 2015. The major finding of this review is that child bilingualism is not related to learning disabilities, namely dyslexia

Η μάθηση γλωσσών μέσω του ίντερνετ δεν είναι κάτι περίεργο για την εκπαίδευση, αλλά στην Ελλάδα φαίνεται να είναι διαφορετικά. Η διδασκαλία της ελληνικής ως ξένης γλώσσας ακολουθούσε την κλασσική μέθοδο αλλά εξελίχθηκε προσπαθώντας να εντάξει τις νέες τεχνολογίες και το Ίντερνετ. Εφαρμογές και ιστοσελίδες κατασκευάστηκαν με σκοπό οι ξένοι μαθητές να έχουν τη δυνατότητα να μάθουν τη γλώσσα. Υπάρχουν λιγοστές εφαρμογές και ιστοσελίδες για τα ελληνικά σε σχέση με άλλες γλώσσες όπως για παράδειγμα τα Αγγλικά.

description: Nowadays mobile learning has expanded in the field of language learning and a new sector has been created, mobile assisted language learning. Learning languages through the Internet is not a strange thing in the education, yet in Greece things seem to be different. The teaching of Greek as a foreign language used to follow the classic methods of teaching yet it evolved trying to integrate new technologies and the Internet. Apps and websites were made in order for foreign students to learn the language. There are limited apps and websites for Greek in comparison with the other languages for example English. The current project attempts to catalog the websites and apps for mobile devices and to evaluate them based on the four abilities of language acquisition

description: This study aims to investigate the possible development of daily spawning pattern and to estimate the batch fecundity between different groups of Atlantic mackerel, Scomber scombrus NEA stock. The estimation of batch fecundity based on whole mounts analysis while particle analysis applied on digital images of ovarian tissue. The study of daily spawning pattern revealed its presence through during the day, therefore Atlantic mackerel, or at least the individuals of the referring stock, develops daily synchronism of oocyte growth. As for the batch fecundity estimation, the value for hydrated oocytes which developed hiatus (before the advance batch) is in consistency with the bibliography while for hydrated oocytes without the development of hiatus appeared significantly overestimated value. This results revealed that the estimation of batch fecundity of hydrated oocytes, without the criterion of the presence of not of hiatus could lead to precarious results.

description: We investigate the importance of quantum orbital fluctuations in the orthorhombic and monoclinic phases of the Mott insulators LaVO3 and YVO3. First, we construct ab-initio material-specific t2g Hubbard models. Then, by using dynamical mean-field theory, we calculate the spectral matrix as a function of temperature. Our Hubbard bands and Mott gaps are in very good agreement with spectroscopy. We show that in orthorhombic LaVO3, quantum orbital fluctuations are strong and that they are suppressed only in the monoclinic 140 K phase. In YVO3 the suppression happens already at 300 K. We show that Jahn-Teller and GdFeO3-type distortions are both crucial in determining the type of orbital and magnetic order in the low temperature phases.

description: Surface electromyogram (sEMG) signals result from muscle movement and hence they are an ideal candidate for benchmarking event-driven sensing and computing. We propose a simple yet novel approach for optimizing the spike encoding algorithm's hyper-parameters inspired by the readout layer concept in reservoir computing. Using a simple machine learning algorithm after spike encoding, we report performance higher than the state-of-the-art spiking neural networks on two open-source datasets for hand gesture recognition. The spike encoded data is processed through a spiking reservoir with a biologically inspired topology and neuron model. When trained with the unsupervised activity regulation CRITICAL algorithm to operate at the edge of chaos, the reservoir yields better performance than state-of-the-art convolutional neural networks. The reservoir performance with regulated activity was found to be 89.72% for the Roshambo EMG dataset and 70.6% for the EMG subset of sensor fusion dataset. Therefore, the biologically-inspired computing paradigm, which is known for being power efficient, also proves to have a great potential when compared with conventional AI algorithms.

Le Conclusioni del Consiglio d'Europa del 23 maggio 2023 sull'editoria editoria scientifica di qualità, trasparente, aperta, affidabile ed equa (9616/23) richiedono lo sviluppo di politiche,  finanziamenti e strategie per sostenere modelli non profit di pubblicazioni open access per ogni tipo di formato, senza costi per autori e lettori, riconoscendo allo stesso tempo che il costo degli abbonamenti e del modello cosiddetto "paywall" produce diseguaglianze e sta diventando insostenibile per le finanze pubbliche - sottraendo fra l'altro fondi alla ricerca.
Sono solo dichiarazioni d'intenti? Solo ottimi principi, ma inattuabili? O la comunità si sta già muovendo in questa direzione, per riprendere controllo della comunicazione scientifica, rispettando la varietà di lingue e formati che crea una necessaria bibliodiversità, in linea con le Raccomandazioni UNESCO per la Open Science?
In questa comunicazione vedremo alcune iniziative concrete intraprese dalla comunità - con particolare riferimento alle scienze umane e sociali, ma non solo - per costruire un sistema di pubblicazioni che risponda ai bisogni di condivisione immediata, qualità, sostenibilità, che a sua volta si traduca in un maggiore impatto sociale per la ricerca. Parleremo di 3 progetti collegati, DIAMAS, CRAFT-OA e PALOMERA, che stanno contribuendo nell'ambito dell'infrastruttura di ricerca OPERAS a rendere il cosiddetto "Diamond Open Access" una realtà, non solo per le scienze umane ma per l'intera comunità scientifica. Presenteremo anche altri servizi quali a piattaforma GoTRIPLE come unico punto di accesso a fonti online di area umanistica, Pathfinder per orientarsi nel panorama dei servizi editoriali, PRISM per la certificazione della qualità, VERA per il dialogo con la società e la citizen science, tutte parte di una strategia complementare messa in atto da OPERAS per creare un percorso sostenibile verso una comunicazione scientifica aperta, equa e sostenibile.

description: We perform a two-dimensional inversion of f-mode travel times to determine near-surface solar flows. The inversion is based on optimally localized averaging of travel times. We use finite-wavelength travel-time sensitivity functions and a realistic model of the data errors. We find that it is possible to obtain a spatial resolution of 2 Mm. The error in the resulting flow estimate ultimately depends on the observation time and the number of travel distances used in the inversion.

description: Regardless of their different types of progenitors and central engines, gamma-ray bursts (GRBs) were always assumed to be standalone systems after they formed. Little attention has been paid to the possibility that a stellar companion can still accompany a GRB itself. This paper investigates such a GRB-involved binary system and studies the effects of the stellar companion on the observed GRB emission when it is located inside the jet opening angle. Assuming a typical emission radius of $\sim10^{15}\,$cm, we show that the blockage by a companion star with a radius of $R_\mathrm{c}\sim67\,\mathrm{R_\odot}$ becomes non-negligible when it is located within a typical GRB jet opening angle (e.g., $\sim10$ degrees) and beyond the GRB emission site. In such a case, an on-axis observer will see a GRB with a similar temporal behavior but 25% dimmer. On the other hand, an off-axis observer outside the jet opening angle (hence missed the original GRB) can see a delayed "reflected" GRB, which is much fainter in brightness, much wider in the temporal profile and slightly softer in energy. Our study can naturally explain the origin of some low-luminosity GRBs. Moreover, we also point out that the companion star may be shocked if it is located inside the GRB emission site, which can give rise to an X-ray transient or a GRB followed by a delayed X-ray bump on top of X-ray afterglows.

First, we study the spin splitting $δε=ε_{\downarrow}-ε_{\uparrow}$ of an energy level in the quantum dot by tunnel couplings to the ferromagnetic leads, using the Poor man's scaling method. The spin splitting takes place in an intermediate direction between magnetic moments in the two leads. $δε\propto p\sqrt{\cos^2(θ/2)+v^2\sin^2(θ/2)}$, where $p$ is the spin polarization in the leads, $θ$ is the angle between the magnetic moments, and $v$ is an asymmetric factor of tunnel barriers ($-1

description: This paper analyzes the effect of curved closed string backgrounds on the stability of D-branes within boundary string field theory. We identify the non-local open string background that implements shifts in the closed string background and analyze the tachyonic sector off-shell. The renormalization group flow reveals some characteristic properties, which are expected for a curved background, like the absence of a stable space-filling brane. In 3-dimensions we describe tachyon condensation processes to lower-dimensional branes, including a curved 2-dimensional brane. We argue that this 2-brane is perturbatively stable. This is in agreement with the known maximally symmetric WZW-branes and provides further support to the bulk-boundary factorization approach to open-closed string correspondence.

description: A number of physical processes in laser-plasma interaction can be described with the two-fluid plasma model. We report on a solver for the three-dimensional two-fluid plasma model equations. This solver is particularly suited for simulating the interaction between short laser pulses with plasmas. The fluid solver relies on two-step Lax-Wendroff split with a fourth-order Runge-Kutta scheme, and we use the PseudoSpectral Analytical Time-Domain (PSATD) method to solve Maxwell's curl equations. Overall, this method is only based on finite difference schemes and fast Fourier transforms and does not require any grid staggering. The PseudoSpectral Analytical Time-Domain method removes the numerical dispersion for transverse electromagnetic wave propagation in the absence of current that is conventionally observed for other Maxwell solvers. The full algorithm is validated by conservation of energy and momentum when an electromagnetic pulse is launched onto a plasma ramp and by quantitative agreement with wave conversion of p-polarized electromagnetic wave onto a plasma ramp.

description: We have assembled an 8.4 GHz survey of bright, flat-spectrum (alpha > -0.5) radio sources with nearly uniform extragalactic (|b|>10 deg) coverage for sources brighter than S_{4.8 GHz} = 65 mJy. The catalog is assembled from existing observations (especially CLASS and the Wright et al. PMN-CA survey), augmented by reprocessing of archival VLA and ATCA data and by new observations to fill in coverage gaps. We refer to this program as CRATES, the Combined Radio All-sky Targeted Eight GHz Survey. The resulting catalog provides precise positions, sub-arcsecond structures, and spectral indices for some 11,000 sources. We describe the morphology and spectral index distribution of the sample and comment on the survey's power to select several classes of interesting sources, especially high energy blazars. Comparison of CRATES with other high-frequency surveys also provides unique opportunities for identification of high-power radio sources.

description: In this paper we recall the concepts of $G$-odometer and $G$-subodometer for $G$-actions, where $G$ is a discrete finitely generated group, which generalize the notion of odometer in the case $G=\ZZ$. We characterize the $G$-regularly recurrent systems as the minimal almost 1-1 extensions of subodometers, from which we deduce that the family of the $G$-Toeplitz subshifts coincides with the family of the minimal symbolic almost 1-1 extensions of subodometers.

Evaluation of diffuse mismatch model for phonon scattering at disordered interfaces

description: Diffuse phonon scattering strongly affects the phonon transport through a disordered interface. The often-used diffuse mismatch model assumes that phonons lose memory of their origin after being scattered by the interface. Using mode-resolved atomic Green's function simulation, we demonstrate that diffuse phonon scattering by a single disordered interface cannot make a phonon lose its memory and thus the applicability of diffusive mismatch model is limited. An analytical expression for diffuse scattering probability based on the continuum approximation is also derived and shown to work reasonably well at low frequencies.

The experience and meaning of infertility for biologically childless infertile men
Creators: name: Webb, Russell E.
Publisher: name: University of British Columbia
Year: 2009

description: A qualitative phenomenological paradigm was used to explore the experience of male factor infertility for childless men. Six men were recruited; three from Vancouver, B.C. and three from Regina, Saskatchewan. The men described their experience of infertility within an individual, in-depth, audiotaped interview. Eight common themes were extrapolated from an analysis of the data. The results indicated that the mens’ experience of male factor infertility included all of the following: (1) intense grief and loss, (2) a sense of powerlessness and loss of control, (3) feelings of inadequacy, (4) betrayal, (5) isolation, (6) a sense of threat or foreboding, (7) a need to overcome or survive, and (8) a need for positive reconstruction of the situation and of the self, whereby, the men found new and positive meanings (or purposes) for an experience that originally seemed meaningless and painful.

description: Nigeria’s rice industry is supported by a number of policies with the ultimate goal of boosting its production to meet a growing demand. Among these policies, the agricultural credit guarantee scheme fund is one of the earliest policy directives implemented to encourage paddy producers’ access to formal credits from commercial banks. Considering decades-long debates on the effectiveness of credit policies in improving various aspects of agricultural production, the question is whether this policy has been effective in driving an expansion in paddy area in Nigeria. To answer this question, this study designed a model representing paddy area with the credit policy as one of the determining variables. Empirical results from an autoregressive distributive lag cointegration estimation technique suggests that Nigeria’s credit guarantee policy has a positive and statistically significant impact on paddy area. The finding, therefore, provide suggestions for sustaining the effectiveness of the agricultural credit policy in the country

Sensitivity of Nuclear Transition Frequencies to Temporal Variation of the Fine Structure Constant or the Strong Interaction
Creators: name: Hayes, A. C.
name: Friar, J. L.
Publisher: name: arXiv
Year: 2007
Subjects: subject: Nuclear Theory (nucl-th)
subject: FOS: Physical sciences

description: There exist in nature a few nuclear isomers with very low (eV) excitation energies, and the combination of low energy and narrow width makes them possible candidates for laser-based investigations. The best candidate is the lowest-energy excited state known in nuclear physics, the 7.6(5) eV isomer of $^{229}$Th. A recent study suggests that a measurement of the temporal variation of the excitation energy of this isomer would have 5-6 orders of magnitude enhanced sensitivity to a variation of the fine structure constant ($α\cong 1/137.036$) or of a strong interaction parameter ($m_q/Λ_{QCD}$). We reexamine the physics involved in these arguments. By invoking the Feynman-Hellmann Theorem we argue that there is no expectation of significantly enhanced sensitivity to a variation in the fine structure constant (beyond that obtained from experimental considerations such as the low energy and narrow width of the isomer). A similar argument applies to the strong interaction, but evaluating the shift due to temporal variations of the underlying parameters of the strong interaction may be beyond current nuclear structure techniques.

description: This dissertation was written in the framework of the M.Ed “Sciences of Language and Culture” in the direction of "Technology and Language Education". It aims to develop a complete student support services system for learners who enroll in courses on asynchronous online learning platforms. The aforementioned system will be able to reduce or eliminate student leakage and early school leavers. The thesis addresses the problem created by the lack or poor organization of relevant services by educational institutions, by combining bibliographic research alongside a comprehensive proposal on the provision of services that have the potential to improve the learning experience in e-learning. This paper is structured in two parts: the written part, followed by the practical one which includes an asynchronous online course, called "Orientation Course"
