description: The economies all around the world is suffering from COVID-19, which has made the entire world panic and the pandemic virus has taken over almost 195 countries in its grip. It is quite evident that the enterprises in the MSME sector are the most vulnerable ones in the era of covid-19 pandemic because of their size, scale of operation, limited financial managerial resources and more importantly they don‟t have the capacity to deal with something so unexpected. Here an attempt is made to identify the problems existing in the way of infusing relief measures to the MSME sector and also evaluates the relief measures for MSMEs announced by the finance minister of India as part of the Atmanirbhar Bharath Abhiyan. A framework for the revival of the MSMEs has also been proposed here as part of the study. As the COVID-19 pandemic is a crisis with an unforeseeable ending, the government and businesses enterprises in every sector have to work together so as to address the root cause of the crisis.

description: We investigate spin and charge current through a quantum dot pumped by a time-varying magnetic field. Using the density matrix method, quantum rate equations for the electronic occupation numbers in the quantum dot are obtained and solved in the stationary state limit for a wide set of setup parameters. Both charge and spin current are expressed explicitly in terms of several relevant parameters and analyzed in detail. The results suggest a way of optimizing experimental setup parameters to obtain an maximal spin current without the charge current flow.

Quantum semi-supervised generative adversarial network for enhanced data classification
Creators: name: Nakaji, Kouhei

Publisher: name: arXiv
Year: 2020
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: In this paper, we propose the quantum semi-supervised generative adversarial network (qSGAN). The system is composed of a quantum generator and a classical discriminator/classifier (D/C). The goal is to train both the generator and the D/C, so that the latter may get a high classification accuracy for a given dataset. The generator needs neither any data loading nor to generate a pure quantum state, while it is expected to serve as a stronger adversary than a classical one thanks to its rich expressibility. These advantages are demonstrated in a numerical simulation.

In particular, we have considered a charged particle with and without an oscillator interaction with noncommuting momentum operators and examined angular momentum backflow in each case and how they differ from each other. We also propose a probability associated with the occurence of angular momentum backflow and investigate whether or not the probability depends on a physical parameter, namely the magnetic field.

description: How magnetism affects the Seebeck effect is an important issue widely concerned in the thermoelectric community yet remaining elusive. Based on a thermodynamic analysis of spin degrees of freedom on varied $d$-electron based ferro- and anti-ferromagnets, we demonstrate that in itinerant or partially itinerant magnetic compounds there exists a generic spin contribution to the Seebeck effect over an extended temperature range from slightly below to well above the magnetic transition temperature. This contribution is interpreted as resulting from transport spin entropy of (partially) delocalized conducting $d$ electrons with strong thermal spin fluctuations, even semiquantitatively in a single-band case, in addition to the conventional diffusion part arising from their kinetic degrees of freedom. As a highly generic effect, the spin-dependent Seebeck effect might pave a feasible way to efficient "magnetic thermoelectrics".

description: The Groenewold-Moyal plane is the algebra A_θ(R^(d+1)) of functions on R^(d+1) with the star-product as the multiplication law, and the commutator [x_μ,x_ν] =i θ_{μν} between the coordinate functions. Chaichian et al. and Aschieri et al. have proved that the Poincare group acts as automorphisms on A_θ(R^(d+1))$ if the coproduct is deformed. (See also the prior work of Majid, Oeckl and Grosse et al). In fact, the diffeomorphism group with a deformed coproduct also does so according to the results of Aschieri et al. In this paper we show that for this new action, the Bose and Fermi commutation relations are deformed as well. Their potential applications to the quantum Hall effect are pointed out. Very striking consequences of these deformations are the occurrence of Pauli-forbidden energy levels and transitions. Such new effects are discussed in simple cases.

description: We apply algorithms based on Lieb-Robinson bounds to simulate time-dependent and thermal quantities in quantum systems. For time-dependent systems, we modify a previous mapping to quantum circuits to significantly reduce the computer resources required. This modification is based on a principle of "observing" the system outside the light-cone. We apply this method to study spin relaxation in systems started out of equilibrium with initial conditions that give rise to very rapid entanglement growth. We also show that it is possible to approximate time evolution under a local Hamiltonian by a quantum circuit whose light-cone naturally matches the Lieb-Robinson velocity. Asymptotically, these modified methods allow a doubling of the system size that one can obtain compared to direct simulation. We then consider a different problem of thermal properties of disordered spin chains and use quantum belief propagation to average over different configurations. We test this algorithm on one dimensional systems with mixed ferromagnetic and anti-ferromagnetic bonds, where we can compare to quantum Monte Carlo, and then we apply it to the study of disordered, frustrated spin systems.

Eccentric Early Migration of Neptune

description: The dynamical structure of the Kuiper belt can be used as a clue to the formation and evolution of the Solar System, planetary systems in general, and Neptune's early orbital history in particular. The problem is best addressed by forward modeling where different initial conditions and Neptune's orbital evolutions are tested, and the model predictions are compared to orbits of known Kuiper belt objects (KBOs). It has previously been established that Neptune radially migrated, by gravitationally interacting with an outer disk of planetesimals, from the original radial distance r < 25 au to its current orbit at 30 au. Here we show that the migration models with a very low orbital eccentricity of Neptune e_N < 0.05 do not explain KBOs with semimajor axes 50 < a < 60 au, perihelion distances q > 35 au and inclinations i < 10 deg. If e_N < 0.05 at all times, the Kozai cycles control the implantation process and the orbits with q > 35 au end up having, due to the angular momentum's z-component conservation, i > 10 deg. Better results are obtained when Neptune's eccentricity is excited to e_N ~ 0.1 and subsequently damped by dynamical friction. The low-e & low-i orbits at 50-60 au are produced in this model when KBOs are lifted from the scattered disk by secular cycles -- mainly the apsidal resonance nu_8 -- near various mean motion resonances. These results give support to a (mild) dynamical instability that presumably excited the orbits of giant planets during Neptune's early migration.

description: The statistics of strongly interacting, ultracold Rydberg gases are governed by the interplay of two factors: geometrical restrictions induced by blockade effects, and quantum mechanical effects. To shed light on their relative roles in the statistics of Rydberg gases, we compare three models in this paper: a quantum mechanical model describing the excitation dynamics within a Rydberg gas, a Random Sequential Adsorption (RSA) process on a Random Geometric Graph (RGG), and a RSA process on a Decomposed Random Intersection Graph (DRIG). The latter model is new, and refers to choosing a particular subgraph of a mixture of two other random graphs. Contrary to the former two models, it lends itself for a rigorous mathematical analysis; and it is built specifically to have particular structural properties of a RGG. We establish for it a fluid limit describing the time-evolution of number of Rydberg atoms, and show numerically that the expression remains accurate across a wider range of particle densities than an earlier approach based on an RSA process on an Erdos-Renyi Random Graph (ERRG). Finally, we also come up with a new heuristic using random graphs that gives a recursion to describe a normalized pair-correlation function of a Rydberg gas. Our results suggest that even without dissipation, on long time scales the statistics are affected most by the geometrical restrictions induced by blockade effects, while on short time scales the statistics are affected most by quantum mechanical effects.

description: We report a successful synthesis of monodisperse L10-FePt nanocrystals which are not only superior in magnetism but also easy to handle through being dispersible in solvents. Thanks to a thick SiO2-coating, the thermal treatment needed to form the L10 structure can be done even at 900 oC without inducing coalescence and coarsening. The protecting shell was thereafter removed in a specific way that enabled us to recover the L10-FePt nanocrystals in a water-dispersion. The SiO2-coated nanocrystals show a high coercivity of 18.5 kOe at room temperature in spite of their core size of only 6.5 nm in diameter, and the hysteresis loop of the water-dispersed nanocrystals, which were frozen under an external field, was almost rectangular indicating that their magnetic and structural orientation could be attained.

Revisiting the role of grooming in DIS

Publisher: name: arXiv
Year: 2021
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: We introduce a novel grooming procedure, which is an extension of the modified MassDrop tagging algorithm, tailored to the needs of deep inelastic scattering (DIS). The new algorithm, which grooms the event as a whole, takes advantage of the natural separation of current and target fragmentation in the Breit frame, in order to eliminate radiation in the beam and central rapidity regions. We study the groomed invariant mass in DIS and within soft-collinear effective theory we construct a factorization theorem for the cross-section in the back-to-back limit. In this limit we show that, up to a normalization factor, the cross-section does not depend on the incoming hadronic matrix element and we propose this measurement at HERA and the future electron-ion collider (EIC) as a probe to hadronization, precision QCD, and cold nuclear matter effects. We also give an event based definition of the Winner-Take-All axis and comment on possible applications.

description: The phase diagram of water harbours many mysteries: some of the phase boundaries are fuzzy, and the set of known stable phases may not be complete. Starting from liquid water and a comprehensive set of 50 ice structures, we compute the phase diagram at three hybrid density-functional-theory levels of approximation, accounting for thermal and nuclear fluctuations as well as proton disorder. Such calculations are only made tractable because we combine machine-learning methods and advanced free-energy techniques. The computed phase diagram is in qualitative agreement with experiment, particularly at pressures $\lesssim$8000 bar, and the discrepancy in chemical potential is comparable with the subtle uncertainties introduced by proton disorder and the spread between the three hybrid functionals. None of the hypothetical ice phases considered is thermodynamically stable in our calculations, suggesting the completeness of the experimental water phase diagram in the region considered. Our work demonstrates the feasibility of predicting the phase diagram of a polymorphic system from first principles and provides a thermodynamic way of testing the limits of quantum-mechanical calculations.
Exploring inductive reasoning, scientific reasoning and science motivation, and their role in predicting STEM achievement across grade levels

description: This study aims to investigate the patterns of students’ performance in inductive reasoning, scientific reasoning and science motivation at different grade levels. We also examined the interaction of these variables with parental factors in predicting students’ STEM achievement. A cross-sectional study assessed 726 participants from the 6th, 8th, 10th and 11th grades in 6 secondary schools. The findings showed that students in the upper grades achieved higher scores on reasoning tests than their counterparts in the lower-grade cohorts, but their motivation toward learning science decreased slightly across the grade cohorts. Although the students performed better on an inductive reasoning test, the developmental patterns were comparable for the results on 2 cognitive tests across grade levels. Generally, we found that inductive reasoning and scientific reasoning were closely tied and that both had a significant effect on STEM achievement, while parents’ education impacted positively on both STEM performance and parental involvement in their children’s schooling. However, parental involvement and science motivation had a minor—and different—influence on students’ STEM achievement in the individual grade cohorts. The implications for enhancing students’ STEM performance are further discussed accordingly.
INTEGRATED HIGH-RESOLUTION STRATIGRAPHY OF THE LOWER OLIGOCENETUSA TUFFITE FORMATION IN THE CALABRO-LUCANO AREAAND SICILY (SOUTHERN ITALY)

description: Shale samples from the volcaniclastic turbidites ascribed to the Tusa Tuffite Formation (Tufiti di Tusa Auct.) cropping out at the Canale Candela section (Calabro-Lucano boundary, southern Italy) have yielded rich, diverse and well-preserved palynomorph and calcareous nannofossil assemblages. They allow the consistent recognition of both dinoflagellate cyst and calcareous nannofossil zones previously defined in bio- and magnetostratigraphically well calibrated pelagic sequences from the central and northern Apennines. Thus they give the Canale Candela section a first order correlation to the standard chronostratigraphic scale with high precision. On this basis, an earliest Oligocene age is assigned to this succession.Poorly preserved sparse palynological and calcareous nannofossil assemblages have been recovered from the Tusa Tuffite at the type-locality (Nebrodi Mountains, NE Sicily). Hence, no biozonation is proposed for the Tusa section. The overall composition of the Tusa assemblages, however, unequivocally supports the correlation with the Canale Candela volcaniclastic turbidites.The detailed age assessment of the Tusa Tuffite outcrops investigated, as well as facies similarities, give a broad regional correlation with other Rupelian volcaniclastic successions of the Alps/Apennines system, namely the Aveto Formation belonging to the Subligurian Domain of the northern Apennines, the Ranzano Formation belonging to the Epiligurian succession of the northern Apennines and the Taveyanne Sandstones of the western Alps. In this framework, we suggest that a single regional event of rise and erosion of a volcanic arc occurred in the Alps/Apennines orogenic system during the Early Oligocene.

A COLLECTION OF FOSSIL VERTEBRATES FROM THE UPPER VALDARNO (CENTRAL ITALY) CALIBRATED IN THE END PLIOCENE TO SPAN 220,000 YEARS ACROSS THE OLDUVAI MAGNETOCHRON

description: The small Faella collection of fossil vertebrates, from the Upper Valdarno (UV) continental sediments, was first assembled in the Natural history museum of Firenze over two centuries ago, reaching 13 specimens for 7 represented species, until in 1967 new finds were retrieved from the Cava Pratigliolmi clay pit. The latter were mainly collected in the lower stratigraphic levels, reaching 29 specimens for 10 species, while the position of the ancient specimens, which are among the most representative ones of the Late Villafranchian mammal age, was tentatively determined from catalogue informations. The magnetic stratigraphy of the clay pit sequence at Faella, and additional controls on their database led to assign them an age of 1775 + - 0.05° Ma. Each recent specimen was assigned a numerical age comprised in the time-span measured in the composite Faella section, extending from 45 ky prior to the onset of the Olduvai magnetochron at 1.95 Ma to shortly before the end of it at 1.77 Ma. The Faella faunal assemblage will therefore play a key role in the geochronology of the UV faunal events, which occurred during the deposition of the Montevarchi intermediate fluvial-deltaic sequence, because the specimens occupy a wide range of ages and the lowermost ones represent the earliest fauna of the late Villafranchian, close to the beginning of the Mammal zone MN 17 of the Neogene classification.. Its magnetostratigraphic date, ranging from 1995 Ma to 1.775 Ma, represents the first example in the UV fossil collections of a measured time span within one assemblage collected in stratigraphic order. The biochronological position of the late Villafranchian reconstructed in the UV, and the present example will represent a criterion for dating most  old collections, especially the classical ones, whenever a magnetostratigraphy of the units containing them will be available for correlation.

description: The present paper attempts to reconstruct cyrenaic gnoseology having demonstrated the school's socratic identity - namely, the application andevolution of socratic notions such as self-discipline, prudence, the ultimate good and pleasure in aristippean ethics. The paper's main subject, with regand to cyrenaic gnoseology, is to show that the protagorean principle «The human being is the measure of all,...», with its scepticism, ultimate subjectivism and relativism, assumes in cyrenaic thought the attributes of gnoseologically limited subjectivism and, to a lesser extent, ontological scepticism.A thorough examination of the ancient sources in which cyrenaic subjectivism and scepticism are manifest is made along the basic gnoseological axis:«Only passions are perceptible; not the causes that generate them».Finally, the much discussed relationship between the cyrenaic and protagorean theories is examined in the context both of ancient greek and modernthought through an investigation of the various interpretations formulated to define this relationship with the utilisation of various selected excerpts fromthe sources, and - mainly - through a reading of Plato's Thaetetus

In particular, L. ionica is known from the "large Gephyrocapsa" up to the Pseudoemiliania lacunosa biozone. Apparently the species became extinct before the end of the Pleistocene. Although the genus Lampadena lives only outside the Mediterranean today, it is known from the Mediterranean realm since the early Miocene. L. ionica seems to be the only species of the genus Lampadena existing in Pleistocene deposits of the Mediterranean area.

description: An extremely fast exponential expansion of the Universe is typical for the stable version of the inflationary model, based on the anomaly-induced action of gravity. The total amount of exponential $e$-folds could be very large, before the transition to the unstable version and the beginning of the Starobinsky inflation. Thus, the stable exponential expansion can be seen as a pre-inflationary semiclassical cosmological solution. We explore whether this stable phase could follow after the bounce, subsequent to the contraction of the Universe. Extending the previous consideration of the bounce, we explore both stable expansion and the bounce solutions in the models with non-zero cosmological constant and the presence of background radiation. The critical part of the analysis concerns stability for small perturbations of the Hubble parameter. It is shown that the stability is possible for the variations in the bounce region, but not in the sufficiently distant past in the contraction phase.

Since we are interested in the cumulative effect of interaction and disorder, we study baths comprising Ising spins with random ferro- and antiferromagnetic interactions between the spins. Using the resolvent operator method which goes beyond the standard Born-Markov master equation approach, we show that, in the weak coupling regime, the decoherence of the central spin at all times is entirely determined by the local-field distribution or equivalently, the dynamical structure factor of the Ising bath. We present analytic results for the Ising spin chain bath at arbitrary temperature for different distributions of the intrabath interaction strengths. We find clear evidence of non-Markovian behavior in the low temperature regime. We also consider baths described by Ising models on higher-dimensional lattices. We find that interactions lead to a significant reduction of the decoherence. An important feature of interacting spinbaths is the saturation of the asymptotic Markovian decay rate at high temperatures, as opposed to the conventional Ohmic boson bath.

description: During the latest Carboniferous and earliest Permian (Virgilian-Wolfcampian), the eastern margin of the Orogrande Basin in south-central New Mexico was rimmed by a narrow, tectonically unstable shelf, on which sediments of the Laborcita and Abo formations were deposited. Sediments of the Hueco Group accumulated on the more stable western margin of the Orogrande Basin. On the eastern shelf, the Laborcita Formation of the northern Sacramento Mountains represents a transition from marine to terrestrial facies and is composed of clastic-carbonate cycles. Limestones accumulated during relative sea-level highstands in a shallow marine shelf environment. Clastic sediments were deposited during relative lowstands when there was strong clastic influx in a nearshore to terrestrial environment. The overlying Abo Formation is composed of terrestrial red beds. On the western shelf, the Shalem Colony Formation of the Hueco Group, equivalent to the Laborcita Formation, is composed of mostly normal marine shallow shelf limestones with only minor interbedded clastics. The Robledo Mountains Formation and Hueco Group reflects a trend from a restricted shallow  shelf and tidal flat clastics facies in the lower part to more open conditions in the upper part, which also prevailed during deposition of the overlying Apache Dam Formation. Limestones of the Laborcita Formation and Hueco Group contain smaller foraminifers, algae and problematic carbonate microfossils. All taxa except two pseudoalgae in open nomenclature (Litostroma (?) sp. and “problematicum gen. 1”) are taxa already described. Compared with the Carnic Alps (Austria/Italy), the assemblages of smaller foraminifers of the Laborcita Formation  and Shalem Colony Formation are very similar to those of the Auernig and Carnizza Formations (Auernig Group), and Lower Pseudoschwagerina Limestone (Rattendorf Group), indicating an Orenbugian (“Bursumian”) to Asselian age. Smaller foraminifers of the Robledo Mountains Formation allow correlation with the Grenzland Formation and Upper Pseudoschwagerina Limestone (Rattendorf Group) of the Carnic Alps, dated as Asselian to Sakmarian. Smaller foraminifers of the Apache Dam Formation suggest an Artinskian age, correlating with the Wolfcampian, or the Trogkofel Group of the Carnic Alps.

description: The welfare centers in the society are among the most dynamic social institutions in the world. Community centers keep people in the center of development, as they have a commitment to regional intervention. To do this, governments provide an institutional link between people and the various private stakeholder coalitions that make up their communities. Community centers also participate in a wide range of social change activities, including advocacy with and on behalf of the community to reform basic social, political and economic conditions. In the world, social workers serve as primary professional leaders of an effective community centers movement. In the literature review, few studies have been found which examine the relations between social services and social Works with respect to the countries. Data Collection Technique of Research; in order to be used in this study, a literature review on the subject was made, and books, theses, articles, and other resources were scanned. Generally to applied theoretical research and evaluation method to be used. In addition, collecting documents from texts, making conceptual and logical analyzes, comparing, understanding, interpreting, analyzing and interpreting as well as improving social works were tried to be used to make solution-oriented suggestions. This article presents an in-depth discussion of global trends that contribute to local context for contemporary social work practices. In addition, the results of social work education were discussed and a number of recommendations were made for social workers to include perspectives in their daily practice.

description: Non-invasive detection of microvascular alterations in deep tissues in vivo provides critical information for clinical diagnosis and evaluation of a broad-spectrum of pathologies. Recently, the emergence of super-resolution ultrasound localization microscopy (ULM) offers new possibilities for clinical imaging of microvasculature at capillary level. Currently, the clinical utility of ULM on clinical ultrasound scanners is hindered by the technical limitations, such as long data acquisition time, and compromised tracking performance associated with low imaging frame-rate. Here we present an in-human ULM on a high frame-rate (HFR) clinical ultrasound scanner to achieve super-resolution microvessel imaging using a short acquisition time (<10s). Ultrasound MB data were acquired from different human tissues, (liver, kidney, pancreatic, and breast tumor) using an HFR clinical scanner. By leveraging the HFR and advanced processing techniques including sub-pixel motion registration, MB signal separation, and Kalman filter-based tracking, MBs can be robustly localized and tracked for successful ULM under the circumstances of relatively high MB concentration and limited data acquisition time in humans. Subtle morphological and hemodynamic information were demonstrated on data acquired with single breath-hold and free-hand scanning. Compared with contrast-enhanced power Doppler generated based on the same MB dataset, ULM showed a 5.7-fold resolution improvement in a vessel, and provided a wide-range flow speed measurement that is Doppler angle-independent. This study demonstrated the feasibility of ultrafast in-human ULM in various human tissues based on a clinical scanner that supports HFR imaging, and showed a great potential for the implementation of super-resolution ultrasound microvessel imaging in a myriad of clinical applications involving microvascular abnormalities and pathologies.

The ethnic church and immigrant integration: social services, cultural preservation and the re-definition of cultural identity
Creators: name: Beattie, Laura Jean

description: Consideration of the significance of religious institutions in the experience of immigrant settlement is, at best, marginalized in immigration and church history literature. The limited amount of research that has been carried out is limited in time frame and/or by its lack of consideration of the wider social service functions of the church. It is rarely recognized that for new immigrants, churches can function as critical access routes to the host society or as protective cultural communities. Churches provide stability in unfamiliar territory through the creation of a sense of community, a sense of place and an extended family of support. This research seeks to understand how the church has served the German ethnic and immigrant community; how the church has aided cultural preservation as well as immigrant integration; and finally, how some churches have re-defined themselves in the face of member 'assimilation,' generational changes and neighbourhood transition. For some churches, their mission has been extended beyond their original German ethnic community to local neighbourhood residents, predominantly of Asian origin. Unstructured interviews with over twenty-five church leaders from ten German ethnic churches in Vancouver suggest that for many immigrants, the church provided stability and acted as a centre of social networks through which, for example, employment and housing were found. However, the position of the church in maintaining culture is significantly more complex; often dependent upon various factors including church age and the histories of immigrant congregations. This research demonstrates that churches have significant but generally unrecognized impacts on the immigrant settlement experience and that ethnic churches can, but do not necessarily, play supportive roles in maintaining culture. Churches that have recognized the social changes impacting their congregations have found new models of mission to integrate new immigrant communities.

description: Η φωτοκαταλυτική αποικοδόμιση του Imidacloprid μελετήθηκε σε δύο φυτοκαταλυτικά συστήματα με τη χρήση τεχνητού φωτισμού : ετερογενές φωτοκαταλυτικό σύστημα με το TiOi και ομογενές φωτοκαταλυτικό σύστημα με το photo-Fenton. Μετρήθηκε ο αρχικός ρυθμός αποικοδόμησης και ανοργανοποίησης του φυτοφαρμάκου κάτω από διαφορετικές συνθήκες. Η συγκέντρωση του imdecloprid που χρησιμοποιήθηκε σε όλα τα πειράματα ήταν τα 20mg/L. Η σύγκριση των δύο μεθόδων έδειξε ότι μετά από 90 λεπτά επεξεργασίας, πραγματοποιήθηκε ανοργανοποίηση κατά 62% στην περίπτωση του photo-Fenton με ακτινοβολία UV-A κατά 20% στην περίπτωση του TiO2, γεγονός που σημαίνει ότι το TOC εμφανίζεται 3,1 φορές γρηγορότερα με το phto-Fenton από ότι με το TiO2. Ακόμη, πραγματοποιήθηκαν μετρήσεις τοξικότητας και ταυτοποίηση των ενδιάμεσων προϊόντων με τη βοήθεια της GC-MS
description: The photocatalytic degradation of imidacloprid has been investigated in two photocatalytic systems using artificial light : heterogeneous photocatalysis with titanium dioxide, and homogeneous photocatalysis with photo-Fenton. The initial rate of degradation and mineralization of the pesticide were measured under different experimental conditions. The concetration of imidecloprid that was used throughout all experiments was 20mg/l. The comparison between the two methods showed that after 90 min of photocatalytic treatment 62% of mineralization was reached in the case of photo-Fenton and UV-A irradiation and 20% in the case of Ti)2 meaning that TOC disappears 3.1 times pastes with photo-Fenton photocatalytic treatment than with TiO2. Thus, toxicity measurements and identification of intermediates during the process with GC-MS, were also concluded

description: The Sakarya section represents a highly fossiliferous part of the Haymana-Polatli basin succession (central Anatolia), consisting of mainly nummulitid, alveolinid and orthophragminid foraminifera.  This section, formerly proposed to serve as a reference section for early Ilerdian-early Cuisian Shalow Benthic Zones in Turkey by the "Early Paleogene working group", was studied for its orthophragminid foraminifera, and a sequence of populations has been subjected to biometric analysis of the embryo and equatorial chamberlets.  Discocyclina, which occurs throughout the section, is mainly represented by primitive specimens of Discocyclina archiaci; D. archiaci bakhchisaraiensis and Discocyclina sp. 1 in the lowermost part, which is regarded as of middle Ilerdian age (orthophragminid zone 3).  Upwards, different developmental stages of D. archiaci; transitional developmental stages of D. archiaci bakhchisaraiensis-staroseliensis and D. archiaci staroseliensis are accompanied sporadically by unribbed Orbitoclypeus, O. schopeni suvlukayensis and Discocyclina sp. 1.  This part of the section is regarded as middle-late Ilerdian in age (orthophragminid zone 4).  A more diverse assemblage, represented by Nemkovella, Asterocyclina, ribbed and unribbed Orbitoclypeus accompanied by different Discocyclina species occurs in the uppermost part, which is thought to represent the transitional late Ilerdian-early Cuisian orthophragminid zones (orthophragminid zone 4/5).  In these horizons, N. strophiolata fermonti, N. evae, primitive developmental stages of D. augustae sourbetensis, O. douvillei douvillei, D. fortisi fortisi, A. stella and O. munieri munieri are accompanied by D. archiaci staroseliensis, transitional developmental stages of D. archiaci staroseliensis-archiaci, O. schopeni suvlukayensis and Discocyclina sp. 2.  Biometric data allow refinements with respect to the stratigraphic ranges of some discocyclinid and orbitoclypeid foraminifera. This paper records the first description of orthophragminids from the middle-late Ilerdian/early Cuisian marine deposits of Turkey.
