description: La parálisis cerebral es una enfermedad neurológica, multifactorial. Se clasifica según el trastorno motor y el área corporal afectada. Se presenta aunada a trastornos permanentes del desarrollo motor limitando a quien lo presenta de forma visual, auditiva, sensitiva y social; así como trastornos de alimentación que son impedimento para una adecuada alimentación, reflejando pobre ingesta calórica y desnutrición, y daño adicional al SNC. Los trastornos de la alimentación comprenden alteraciones como: Disfagia, reflujo gastroesofágico, sialorrea, entre otros. La atención representa un reto, debido a la dificultad del manejo conductual, sin embargo, deberán estar capacitados para brindar la mejor atención, y concientizar a los cuidadores sobre la importancia de la higiene bucal. La malnutrición es un grave problema de salud que afecta la calidad de vida en los pacientes con parálisis cerebral, aumenta la mortalidad y genera alta demanda económica al sector salud y la familia del paciente.

description: Nanoelectromechanical systems (NEMSs) are emerging nanoscale elements at the crossroads between mechanics, optics and electronics, with significant potential for actuation and sensing applications. The reduction of dimensions compared to their micronic counterparts brings new effects including sensitivity to very low mass, resonant frequencies in the radiofrequency range, mechanical non-linearities and observation of quantum mechanical effects. An important issue of NEMS is the understanding of fundamental physical properties conditioning dissipation mechanisms, known to limit mechanical quality factors and to induce aging due to material degradation. There is a need for detection methods tailored for these systems which allow probing motion and stress at the nanometer scale. Here, we show a non-invasive local optical probe for the quantitative measurement of motion and stress within a multilayer graphene NEMS provided by a combination of Fizeau interferences, Raman spectroscopy and electrostatically actuated mirror. Interferometry provides a calibrated measurement of the motion, resulting from an actuation ranging from a quasi-static load up to the mechanical resonance while Raman spectroscopy allows a purely spectral detection of mechanical resonance at the nanoscale. Such spectroscopic detection reveals the coupling between a strained nano-resonator and the energy of an inelastically scattered photon, and thus offers a new approach for optomechanics.

description: El hijo de un conquistador español con la hermana del cacique de Turmequé, Diego de Torres (Tunja 1549 - Madrid 1590) es conocido por sus denuncias sobre la corrupción de los funcionarios de la Corona española en el Nuevo Reino de Granada (que corresponde aprox- imadamente a la actual Colombia) y su trato a la población indígena muisca, así como por su reivindicación del cacicazgo de Turmequé. Clasificado como pueblo de indios según la organización territorial española de la región, Turmequé dependía de la jurisdicción de Tunja, importante centro artístico, cuya propia imagen como ciudad española se estaba construyendo en la segunda mitad del siglo XVI. Educado en Tunja, primero en un colegio de mestizos y luego con los dominicos, Diego de Torres pertenecía a una particular élite colonial que ocupaba espacios simultáneamente en las sociedades española y muisca, pero que no pertenecía del todo a ninguna de ellas. Aunque la documentación relativa a sus quejas y viajes a España ha sido abordada tanto en estudios literarios como jurídicos, los dibujos que realizó junto a su memorial de agravios no han recibido suficiente atención. Además de dos mapas de la región analizados por Tom Cummins y Joanne Rappaport como parte de la alfabetización impuesta a los indígenas de los Andes, se destaca por su combinación de géneros y estilo el dibujo de una escena fúnebre que representa al hermano de Diego de Torres (Pedro de la Torre) en su lecho de muerte rodeado de familiares y amigos. Este artículo explora el funcionamiento retórico de estos dibujos, que a su vez reflejan la lucha de mestizos cuyas identidades estaban en constante cambio y atrapadas en una encrucijada.

description: Based on a compilation of OVI, CIV, SiIV and NV data from IUE, FUSE, GHRS, STIS, and COS, we derive an anti- correlation between the stellar temperature and the high ion velocity shift w.r.t. to the photosphere, with positive (resp. negative) velocity shifts for the cooler (resp. hotter) white dwarfs. This trend probably reflects more than a single process, however such a dependence on the WD's temperature again favors a CS origin for a very large fraction of those ion absorptions, previously observed with IUE, HST-STIS, HST-GHRS, FUSE, and now COS, selecting objects for which absorption line radial velocities, stellar effective temperature and photospheric velocity can be found in the literature. Interestingly, and gas in near-equilibrium in the star vicinity. It is also probably significant that the temperature that corresponds to a null radial velocity, i.e. \simeq 50,000K, also corresponds to the threshold below which there is a dichotomy between pure or heavy elements atmospheres as well as some temperature estimates for and a form of balance between radiation pressure and gravitation. This is consistent with ubiquitous evaporation of orbiting dusty material. Together with the fact that the fraction of stars with (red-or blue-) shifted lines and the fraction of stars known to possess heavy species in their atmosphere are of the same order, such a velocity-temperature relationship is consistent with quasi-continuous evaporation of orbiting CS dusty material, followed by accretion and settling down in the photosphere. In view of these results, ion measurements close to the photospheric or the IS velocity should be interpreted with caution, especially for stars at intermediate temperatures. While tracing CS gas, they may be erroneously attributed to photospheric material or to the ISM, explaining the difficulty of finding a coherent pattern of the high ions in the local IS 3D distribution.

description: In this article I attempt to analyze the social memories of wives of soldiers in service on April 25th 1974, through the methodology of analysis recommended by Adele Clarke (2005), using data collected in 11 interviews conducted between 2005 and 2008 under a PhD project. As a conceptual framework I adopt the perspective of social memory in the tradition of Halbwachs (1992) and following Marc Augé (2001) and Paul Ricoeur (2004), which emphasizes the social and collective memory and points out the dynamic role it plays in building a meaning to the world. This analysis takes into account the dimensions of work, family, education, politics and social life, social and economic conditions and the expectations and dreams on which the interviewees draw comparisons between 1974 and the present and also produce judgments.

description: Ten percent of the participants in U.S. commodity programs for wheat, feed grains, cotton, and rice received 47 percent of the 1978 payments. Those farmers were the largest participants, having 500 acres or more of crops. The smallest 50 percent of participants received 10 percent of the payments. The $40,000 ceiling on payments to individuals had a negligible effect on the distribution of payments: the limit affected only 0.16 percent of participants, and payments foregone amounted to only 1.33 percent of the total. Proposals to prohibit payments to corporations would not have a significant impact because few corporations grow program commodities.

Modernity devoured: Re-viewing the Anthropocene with Oswald de Andrade’s concept of anthropophagy
Creators: name: Robalinho, Roberto
Publisher: name: Miradas - Journal for the Arts and Culture of the Américas and the Iberian Peninsula
Year: 2023

description: Certain images produced by nature as a result of ecological disasters and climate crisis challenge our classic representation paradigm based on the separation between nature and culture. At the same time, these contemporary images, evoke a complex temporality of an apocalyptic future arriving sooner than expected and a colonial past that never seizes to violently consume natural resources. This paper proposes to revisit the Brazilian 1928 Anthropophagic Manifest, one of Latin America’s founding epistemologies according to Boaventura Souza Santos, as an aesthetic, philosophical and pragmatical proposal capable of providing tools to address our present crisis and these challenging images of the Anthropocene. How can a cannibalistic (indigenous) past set the grounds for creative invention and anti-colonial art? How can this transcultural use of indigenous philosophy help us find tools not only to frame these images of the Anthropocene, but above all, offer possibilities of surviving the “end of the world”?

Schroedinger current for discontinuous states from the first passage time decomposition

Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: We revisit the problem of calculating the probability current for discontinuous states, such that may arise in atom trapping or as a result of projective measurements. In the first passage time representation, the problem reduces to evaluation of a localised wave originating from the discontinuity, whose interference with the initial state determines the transfer of probability. Depending on the type of discontinuity, the current behaves as $t^{1/2}$, $t^{3/2}$ or $const(t)$. Our approach generalises earlier work on this subject.

description: Laser-driven Bose-Einstein condensate of ultracold atoms loaded into a lossy high-finesse optical resonator exhibits critical behavior and, in the thermodynamic limit, a phase transition between stationary states of different symmetries. The system realizes an open-system variant of the celebrated Dicke-model. We study the transition for a finite number of atoms by means of a Hartree-Fock-Bogoliubov method adapted to a damped-driven open system. The finite-size scaling exponents are determined and a clear distinction between the non-equilibrium and the equilibrium quantum criticality is found.

description: PageRank (PR) is an algorithm originally developed by Google to evaluate the importance of web pages. Considering how deeply rooted Google's PR algorithm is to gathering relevant information or to the success of modern businesses, the question of rank-stability and choice of the damping factor (a parameter in the algorithm) is clearly important. We investigate PR as a function of the damping factor d on a network obtained from a domain of the World Wide Web, finding that rank-reversal happens frequently over a broad range of PR (and of d). We use three different correlation measures, Pearson, Spearman, and Kendall, to study rank-reversal as d changes, and show that the correlation of PR vectors drops rapidly as d changes from its frequently cited value, $d_0=0.85$. Rank-reversal is also observed by measuring the Spearman and Kendall rank correlation, which evaluate relative ranks rather than absolute PR. Rank-reversal happens not only in directed networks containing rank-sinks but also in a single strongly connected component, which by definition does not contain any sinks. We relate rank-reversals to rank-pockets and bottlenecks in the directed network structure. For the network studied, the relative rank is more stable by our measures around $d=0.65$ than at $d=d_0$.

RESUMEN Los glifos de los amantecas. Escritura y arte plumario en el Códice Florentino

description: Este artículo propone una lectura para todos los glifos incertos en las imágenes que acom-pañan el capítulo 21 del libro IX del Códice Florentino, siguiendo el trabajo de desciframiento iniciado por Frances Berdan (2015). Estas imágenes representan el proceso de trabajo de plumaria a principios del período colonial, expresando los nombres de los materiales uti-lizados por los artistas de la pluma o amanteca, sus propiedades, así como las acciones implicadas en la fabricación de sus obras de arte. El análisis de estos glifos demuestra que constituyen una especie de “manual de instrucciones”, y posiblemente una de las formas de transmisión del arte y la artesanía entre los indígenas de México durante el siglo XVI, época de fuerte transculturación. El análisis también revela cómo los enfoques estrictamente fonocéntricos de la gramatología son insuficientes para abordar la complejidad de la escritura azteca y para comprender sus posibilidades comunicativas. En su lugar, proponemos que en estas páginas, las imágenes funcionan junto con los glifos logosilábicos, codificando ‘textos incorporados’, como los define Janet Berlo (1983), textos que tenían cierto grado de indepen-dencia de los escritos en español e incluso de los en náhuatl alfabético, por lo que pueden considerarse como verdaderas pictografías, textos indígenas con el potencial de descolonizar nuestra idea de escritura.

description: Spin-orbit coupling (SOC), the intrinsic interaction between a particle spin and its motion, is responsible for various important phenomena, ranging from atomic fine structure to topological condensed matter physics. The recent experimental breakthrough on the realization of SOC for ultra-cold atoms provides a completely new platform for exploring spin-orbit coupled superfluid physics. However, the SOC strength in the experiment, determined by the applied laser wavelengths, is not tunable. In this Letter, we propose a scheme for tuning the SOC strength through a fast and coherent modulation of the laser intensities. We show that the many-body interaction between atoms, together with the tunable SOC, can drive a \textit{quantum phase transition} (QPT) from spin-balanced to spin-polarized ground states in a harmonic trapped Bose-Einstein condensate (BEC). This transition realizes the long-sought QPT in the quantum Dicke model, and may have important applications in quantum optics and quantum information. We characterize the QPT using the periods of collective oscillations (center of mass motion and scissors mode) of the BEC, which show pronounced peaks and damping around the quantum critical point.

The evolution of subcritical Achlioptas processes

Subjects: subject: Probability (math.PR)

description: In Achlioptas processes, starting from an empty graph, in each step two potential edges are chosen uniformly at random, and using some rule one of them is selected and added to the evolving graph. Although the evolution of such `local' modifications of the Erd{\H o}s--Rényi random graph process has received considerable attention during the last decade, so far only rather simple rules are well understood. Indeed, the main focus has been on `bounded-size' rules, where all component sizes larger than some constant $B$ are treated the same way, and for more complex rules very few rigorous results are known. In this paper we study Achlioptas processes given by (unbounded) size rules such as the sum and product rules. Using a variant of the neighbourhood exploration process and branching process arguments we show that certain key statistics are tightly concentrated at least until the susceptibility (the expected size of the component containing a randomly chosen vertex) diverges. Our convergence result is most likely best possible for certain rules: in the later evolution the number of vertices in small components may not be concentrated. Furthermore, we believe that for a large class of rules the critical time where the susceptibility `blows up' coincides with the percolation threshold.

description: In this paper we construct a graded universal enveloping algebra of a $G$-graded Lie algebra, where $G$ is not necessarily an abelian group. If the grading group is abelian, then it coincides with the classical construction. We prove the existence and uniqueness of the graded enveloping algebra. As consequences, we prove a graded variant of Witt's Theorem on the universal enveloping algebra of the free Lie algebra, and the graded version of Ado's Theorem, which states that every finite-dimensional Lie algebra admits a faithful finite dimensional representation. Furthermore we investigate if a Lie grading is equivalent to an abelian grading.

description: Weeds are wild plants grow in an environment without the contribution of any human activities that that have positive or negative impact to the environment. The study aims at carrying a survey on weeds of family Poaceae grown in cultivated environment with purpose of recording and identification. The study was conducted in the Taif region of Saudi Arabian kingdom in a mountain with an elevation level of (Area A = Al sail 1700 m, Area B = Al Wahat and Al Watit 1500, C = Leeih 1500, D = AL Gaim and Saisad 1500, F = E = Al Shafa 2200 m, F = AL Hada = 2000 m). The study was conducted during December 2017 to December 2018. The study was carried out based on environmental survey. Diverse number of weeds were identified and collected from the examined study area. Results revealed 23 species of weeds from the family in the study field. Rosa damascene have the highest number of abundances with 656, followed by Digitaria sanguinalis 618, Cynodon dactylon 562 and Minuartia filifolia with least abundance 17 among all the documented species. The study provided the base line information on the diversity and distribution of weeds from the family Poaceae which will be used for the control of weeds in the area to enhance agricultural productivity in terms of quality and yield. Also has provided insight on purposeful weeds control in Taif Area. The study recommends further studies on order types of weeds in the area.

Amantecayotl Glyphs Revisited: Writing and Featherworking in the Florentine Codex
Creators: name: Zamora Corona, Alonso Rodrigo
name: Savkic Sebek, Sanja
Publisher: name: Miradas - Journal for the Arts and Culture of the Américas and the Iberian Peninsula
Year: 2023

description: This article proposes a reading for all the glyphs infixed in the images which accompany the twenty-first chapter of Book 9 of the Florentine Codex, following the decipherment work initiated by Frances Berdan (2015). These images depict the process of featherworking during the early colonial period, expressing the names of the materials used by the feather artists or amanteca, their properties, as well as the actions involved in the manufacture of their artworks. The analysis of these glyphs shows that they constitute a sort of technical ‘instruction manual’, and possibly corresponded to one of the ways in which arts and crafts were transmitted among the indigenous people of Mexico during the sixteenth century, an era of strong transculturation. The analysis also reveals how strict phonocentric approaches in grammatology are insufficient to tackle the complexity of Aztec writing and to understand its communicative possibilities. Instead, we propose that, in these pages, images work together with logosyllabic glyphs, codifying ‘embedded texts’, as defined by Janet Berlo (1983), texts which had a degree of independence from those written in Spanish and even alphabetic Nahuatl, and hence can be considered as true pictographies, indigenous texts with the potential to decolonise our idea of writing.

description: At least 43 percent of the 127 million acres of U.S. land with high or medium potential for cropland is held by landowners whose characteristics may inhibit cropland development. Owners of potential cropland tend to have smaller holdings, lower net farm incomes, and less active involvement in agriculture than current cropland owners. About 20 percent of the potential cropland lies in small or fragmented holdings or faces competition from urbanization or nonagricultural uses. Another 23 percent is owned by those with short planning horizons and capital problems.

description: Two classes of conservative, linear, optical rotary effects (optical activity and Faraday rotation) are distinguished by their behavior under time reversal. In analogy with coherent perfect absorption, where counterpropagating light fields are controllably converted into other degrees of freedom, we show that only time-odd (Faraday) rotation is capable of coherent perfect rotation in a linear and conservative medium, by which we mean the complete transfer of counterpropagating coherent light fields into their orthogonal polarization. This highlights the necessity of time reversal odd processes (not just absorption) and coherence in perfect mode conversion and may inform device design.

Global questions for evolution equations Landau-Lifshitz flow and Dirac equation
Creators: name: Guan, Meijiao
Publisher: name: University of British Columbia
Year: 2010

description: This thesis concerns the stationary solutions and their stability for some evolution equations from physics. For these equations, the basic questions regarding the solutions concern existence, uniqueness, stability and singularity formation. In this thesis, we consider two different classes of equations: the Landau-Lifshitz equations, and nonlinear Dirac equations. There are two different definitions of stationary solutions. For the Landau-Lifshitz equation, the stationary solution is time-independent, while for the Dirac equation, the stationary solution, also called solitary wave solution or ground state solution, is a solution which propagates without changing its shape. The class of Landau-Lifshitz equations (including harmonic map heat flow and Schrödinger map equations) arises in the study of ferromagnets (and anti-ferromagnets), liquid crystals, and is also very natural from a geometric standpoint. Harmonic maps are the stationary solutions to these equations. My thesis concerns the problems of singularity formation vs. global regularity and long time asymptotics when the target space is a 2-sphere. We consider maps with some symmetry. I show that for m-equivariant maps with energy close to the harmonic map energy, the solutions to Landau-Lifshitz equations are global in time and converge to a specific family of harmonic maps for big m, while for m =1, a finite time blow up solution is constructed for harmonic map heat flow. A model equation for Schrödinger map equations is also studied in my thesis. Global existence and scattering for small solutions and local well-posedness for solutions with finite energy are proved. The existence of standing wave solutions for the nonlinear Dirac equation is studied in my thesis. I construct a branch of solutions which is a continuous curve by a perturbation method. It refines the existing results that infinitely many stationary solutions exist, but with uniqueness and continuity unknown. The ground state solutions of nonlinear Schrodinger equations yield solutions to nonlinear Dirac equations. We also show that this branch of solutions is unstable. This leads to a rigorous proof of the instability of the ground states, confirming non-rigorous results in the physical literature.

description: Mobile Commerce is gaining increasing acceptance amongst various sections of the society. This growth can be partly traced back to technological and demographical developments that have been influencing important aspects of the socio-cultural behaviour in today’s world. The need/wish for mobility seems to be the driving force behind Mobile Commerce in general. Mobile Banking, availment of bank-related financial services via mobile devices, builds a cornerstone of Mobile Commerce. An empirical survey of customer acceptance conducted within the frame of our research clearly reveals a major, growing interest in Mobile Banking. However, since the degree of interest and the willingness to pay vary for individual services, it seems to be necessary to design specific services taking the needs and wishes of relevant target groups into consideration. Banks ought to therefore employ mobile channels with a clear business-focus. This paper examines the opportunities for banks to generate revenues by offering value-added, innovative mobile financial services while retaining and even extending their base of technology-savvy customers.

description: Magnetic fields have been measured around Asymptotic Giant Branch (AGB) stars of all chemical types using maser polarization observations. If present, a large-scale magnetic field would lead to X-ray emission, which should be observable using current X-ray observatories. The aim of this work is to search the archival data for AGB stars that are intrinsic X-ray emitters. We have searched the ROSAT, CXO, and XMM archives for serendipitous X-ray observations of a sample of ~500 AGB stars. We specifically searched for the AGB stars detected with GALEX. The data is calibrated, analyzed and the X-ray luminosities and temperatures are estimated as functions of the circumstellar absorption. We identify 13 AGB stars as having either serendipitous or targeted observations in the X-ray data archives, however for a majority of the sources the detailed analysis show that the detections are questionable. Two new sources are detected by ROSAT: T Dra and R UMa. The spectral analysis suggests that the emission associated with these sources could be due to coronal activity or interaction across a binary system. Further observations of the detected sources are necessary to clearly determine the origin of the X-ray emission. Moreover, additional objects should be subject to targeted X-ray observations in order to achieve better constraints for the magnetic fields around AGB stars.

description: We have started using smart devices, new technologies, gadgets, apps, and multiple systems and services available over the internet long back (Kolâs, L., Nordseth, H. &Munkvold, R.,2016). Technological advances have changed the educational system to an extent, especially since the shift took place due to COVID pandemic.Sruthi, P. and Mukherjee, S. (2020) have stated that, in the past e-year when education was on its digital vigor we have transformed a lot, but this shift has also brought about new concerns like; usefulness, what, how and when related to available applications. Present research attempt to identify the use of educational apps among secondary school studentswith the help of survey method. Data collected from 116 secondary school students and analyzed, presented in percentage. Data reveals the usefulness of educational apps in learning process.
The Dimensional Cost of Erasure: Dissipative Systems, Landauer Limits, and the Hidden Structure of Noise
Creators: name: Todd, Ian
Publisher: name: Zenodo
Year: 2025

description: This paper proposes a fundamental reconceptualization of information dynamics by linking dissipation, dimensionality, and information preservation. Building on Landauer’s principle and Prigogine’s dissipative structures, I argue that information era- sure constitutes not merely an energy cost but a dimensional collapse—a quantifiable reduction in a system’s potential manifold of states. Systems that resist deterministic erasure preserve critical correlations that enable dimensional expansion and emergent complexity. I demonstrate how the seemingly random “noise” in biological and physical systems often contains hidden manifolds of coherence that support adaptation and intelligence, quantifiable through measures of effective dimensionality and multivariate mutual information. This stands in contrast to deterministic computational systems which, in their pursuit of clarity, systematically eliminate dimensionality through era- sure operations. This framework offers new insights into the nature of complexity, adaptability, and the thermodynamic foundations of intelligence, with testable predictions across physical, biological, and computational domains.

description: Womit kann geschlechtstypisches Berufs- und Studienwahlverhalten erklärt werden und wie kann das Berufswahlspektrum von jungen Frauen erweitert werden? Um auf diese Fragen eine Antwort zu geben, hat das Wirtschaftsministerium Baden-Württemberg auf Empfehlung des Landesausschusses für Berufsbildung das Gutachten „Neue Wege in Technik und Naturwissenschaften – Zum Berufswahlverhalten von Mädchen und jungen Frauen“ in Auftrag gegeben. Die Ergebnisse zeigen eindrucksvoll, wie stark das Berufswahlverhalten junger Frauen bis zum heutigen Tag durch ihre Geschlechterrolle geprägt ist und welche Faktoren die typisch weibliche Berufsentscheidung beeinflussen. Schließlich werden auf Grundlage der Ergebnisse konkrete Empfehlungen für künftige Modellversuche gegeben.

description: We study Josephson junctions between superconductors connected through the helical edge states of a two-dimensional topological insulator in the presence of a magnetic barrier. As the equilibrium Andreev bound states of the junction are 4Pi-periodic in the superconducting phase difference, it was speculated that, at finite dc bias voltage, the junction exhibits a fractional Josephson effect with half the Josephson frequency. Using the scattering matrix formalism, we show that signatures of this effect can be seen in the finite-frequency current noise. Furthermore, we discuss other manifestations of the Majorana bound states forming at the edges of the superconductors.

title: Long-term behavior of per- and polyfluorinated alkyl substances (PFAS) on contaminated agricultural sites in Germany

description: Die Stoffgruppe der per- und polyfluorierte Alkylsubstanzen (PFAS) umfasst mehrere tausend Einzelverbindungen. PFAS sind wasser- und fettabweisend und besitzen darüber hinaus eine hohe chemische sowie thermische Stabilität. Einige PFAS können in der Umwelt unter anderem zu perfluorierten Carboxylsäuren (PFCAs) und Sulfonsäuren (PFSA) abgebaut werden. Diese abbaubaren Verbindungen werden auch als Präkursoren bezeichnet. Die entstehenden PFCAs und PFSAs sind in der Umwelt jedoch persistent und können so auch in den entlegensten Umweltkompartimenten nachgewiesen werden. In dieser Arbeit wurden verschiedene Ackerböden aus dem Raum Rastatt/Mannheim beprobt, um in Laborversuchen das Freisetzungsverhalten von PFAS zu untersuchen. In ausführlichen Säulenversuchen konnte festgestellt werden, dass PFCA der Kettenlänge C4-C8 schnell mobilisiert und aus den Böden ausgetragen werden. Mit zunehmender Kettenlänge (PFCAs >C8) verlangsamt sich die Freisetzung und es verbleiben immer größere Anteile im Boden. So betrug die durchschnittliche Wiederfindung der C4-C8 PFCAs im Säuleneluat 104-111% (vollständige Austragung), während für die längerkettigen PFCAs die Wiederfindung auf 7% sinkt. Es wurde jedoch auch festgestellt, dass bei C4-C8 PFCAs ab einem WF >4 die Konzentrationen im Eluat nicht weiter abfallen und sich ein relativ konstantes Konzentrationsniveau einstellt. Vermutet wird, dass dies möglicherweise auf den kontinuierlichen Abbau von Präkursoren in der Säule zurückführen ist, das zu dem anhaltenden Tailing der C4-C8 PFCAs führt. In den Langzeit-Monitoring-Daten aus BS-NRW konnte ein ähnliches Verhalten wie in den Säulenversuchen beobachtet werden. Auch dort wurden kontinuierliche PFCAs- und PFSAs- Austragungen beobachtet. Eine statistische Auswertung der Daten ergab saisonale Einflüsse auf das Austragungsverhalten der meisten Verbindungen. In Mikrokosmen-Versuchen (Batch-Tests) konnte die Produktion von C4-C8 PFCA aus Präkursoren nachgewiesen werden. Qualitativ ähneln die Verteilungsmuster aus den Batch-Tests den im Grundwasser hauptsächlich gefundenen PFAS. Es ist daher davon auszugehen, dass durch die Transformation der Präkursoren in den oberen Bodenschichten zu mobilen PFCA die Kontamination des Grundwassers verursacht wurde. Dies bedeutet, dass die Kontamination des Grundwassers mit PFCAs so lange anhält, bis das Reservoir an Präkursoren erschöpft ist.
