    Lascar described E_KP as a composition of E_L and the topological closure of EL. We generalize this result to some other pairs of equivalence relations. Motivated by an attempt to construct a new example of a non-G-compact theory, we consider the following example. Assume G is a group definable in a structure M. We define a structure M_0 consisting of M and X as two sorts, where X is an affine copy of G and in M_0 we have the structure of M and the action of G on X. We prove that the Lascar group of M_0 is a semi-direct product of the Lascar group of M and G/G_L. We discuss the relationship between G-compactness of M and M_0. This example may yield new examples of non-G-compact theories.Comment: 18 page

    Series : Lecture notes in computer science, ISSN 0302-9743, vol. 8929With the growing popularity of micro-task crowdsourcing platforms, new workflow-based micro-task crowdsourcing approaches are starting to emerge. Such workflows occur in legal, political and conflict resolution do-mains as well, presenting new challenges, namely in micro-task specification and human-machine interaction, which result mostly from the flow of unstruc-tured data. Domain ontologies provide the structure and semantics required to describe the data flowing throughout the workflow in a way understandable to both humans and machines. This paper presents a method for the construction of micro-task workflows from legal domain ontologies. The method is currently being employed in the context of the UMCourt project in order to formulate in-formation retrieval and conflict resolution workflows.This work is part-funded by FEDER Funds, by the ERDF (Eu-ropean Regional Development Fund) through the COMPETE Programme (operation-al programme for competitiveness) and by National Funds through the FCT (Portu-guese Foundation for Science and Technology) within the project FCOMP-01-0124-FEDER-028980 (PTDC/EEI-SII/1386/2012).

    First tests of the applicability of γ\gamma-ray imaging for background discrimination in time-of-flight neutron capture measurements

    Full text link
    In this work we explore for the first time the applicability of using γ\gamma-ray imaging in neutron capture measurements to identify and suppress spatially localized background. For this aim, a pinhole gamma camera is assembled, tested and characterized in terms of energy and spatial performance. It consists of a monolithic CeBr3_3 scintillating crystal coupled to a position-sensitive photomultiplier and readout through an integrated circuit AMIC2GR. The pinhole collimator is a massive carven block of lead. A series of dedicated measurements with calibrated sources and with a neutron beam incident on a 197^{197}Au sample have been carried out at n_TOF, achieving an enhancement of a factor of two in the signal-to-background ratio when selecting only those events coming from the direction of the sample.Comment: Preprint submitted to Nucl. Instr. and Meth.

    Chemical-induced Pancreatitis in a Peritoneal Dialysis Patient at South Texas: A Case Report

    Get PDF
    Introduction: Acute pancreatitis is the leading cause of gastrointestinal-related hospitalization in the United States. Pancreatitis is often linked to excessive alcohol consumption or gallstones, accounting for 80% of all cases. However, in some cases, it can be drug-induced acute pancreatitis (DIP) or via chemical injury. Icodextrin (Extraneal) is a high-molecular-weight glucose polymer developed as an alternative osmotic agent to dextrose in peritoneal dialysis (PD). It is regarded as biocompatible due to its iso-osmolarity, making it generally safe and well-tolerated. While rare, cases have been reported associating icodextrin with pancreatitis; nevertheless, specific rates of icodextrin-induced pancreatitis are unknown. In this case, we present a long-term PD patient recently exposed to Icodextrin and presented with acute pancreatitis. Case Presentation: A 58-year-old male with a significant clinical history of end-stage renal disease on peritoneal dialysis, type 2 diabetes mellitus, and uncontrolled hypertension presented to the emergency department with worsening abdominal pain. The pain was described as sharp in the epigastric area, severe intensity, stabbing-like sensation, and had a sudden onset approximately 6 hours before seeking medical attention. Additionally, he reported associated symptoms of nausea and non-bilious vomiting. There were no other associated symptoms. As relevant past medical history, the patient did mention that 1-2 days prior, he got a new dialysate to continue his dialysis at home, and 6 hours after he had had his first session with this new dialysate, he developed the clinical presentation. Upon arrival, his vital signs were T 98 C, HR 67/min, RR 20/min, BP 127/64 mm Hg, and SPO2 of 98% on room air. Physical examination was remarkable for tenderness in the epigastrium, but there was no evidence of guarding or rigidity. The peritoneal catheter was without any signs of infection. Labs on admission were significant for WBC 8.9 (units and reference values for all the labs), Hb 12.4 (13.5 - 17.5 g/dl), Hct 36.3 (38.8 - 50.0%), Na 136 (136 - 145 mmol/L), K 3.0 (3.5 - 5.3 mmol/L), Cl 97 (98 - 110 mmol/LI), HCO 33.8 (20- 31 mmol/l), and creatinine 7.8.[ASP2] LIPASE[ASP3] 2555 (25-200 U/L). CT of the abdomen with and without contrast reported moderate ascites and a dialysis catheter in place. The patient was admitted due to acute pancreatitis. Fluid and pain management was provided, and a workup to elucidate the cause was started. Gallbladder US was negative for any biliary stones. The lipid panel had no hypertriglyceridemia, and peritoneal fluid analysis did not suggest infection. Since the only apparent cause for this clinical presentation was the new dialysate use, the patient was held his next session of PD, and nephrology consulted for further advice. The patient had interval improvement in the next 24 hours, and Nephrology recommended exchanging the dialysate. The patient was safely discharged after 24 hours, tolerating diet and having no pain. Discussion: DIP is a multifaceted condition, often arising from various pharmaceutical agents (reference). Maintaining a heightened suspicion of DIP when evaluating patients with pancreatitis symptoms is paramount (reference). This vigilance enables timely diagnosis and the cessation of medications or chemicals responsible for the condition, emphasizing the critical need for close monitoring and swift action in the presence of suspected adverse drug effects on the pancreas (reference). Icodextrin, a common component in peritoneal dialysis solutions, is generally well tolerated and appears to be most helpful in situations of reduced or inadequate UF with dextrose, including in high and high-average transporters, during episodes of peritonitis and patients who have failed dextrose-based dialysis (2). However, it can contribute to Icodextrin-induced acute pancreatitis (reference). Notably, Icodextrin interferes with amylase determination in serum, causing a significantly decreased plasma amylase level, making it unreliable for diagnosing acute pancreatitis (reference). Lipase measurement provides an alternative and accurate method for diagnosing acute pancreatitis (AP) in patients using Icodextrin (3). In this context, it is essential to emphasize the need for cautious monitoring and awareness of potential complications when using Icodextrin in PD. Healthcare providers should remain vigilant and consider this rare adverse event when assessing patients undergoing peritoneal dialysis with Icodextrin-containing solutions and be aware of potential complications and this rare adverse event

    The study of a great part of the material found during the excavation work carried out by a team of the «Institut de Paleontología de Sabadell» and other paleontologists of the universities of Madrid and Bellaterra, in the basin of Tremp (Maastrichtiense) in 1984 and 1985 has made possible the recognition of: 1.º A large sized Crocodilian, attributable to an adult animal of the Alligatoridae family, comparable to Crocodilus affluvelensis. 2.° Dinosaur remains atributed to three difIerent families: Atlantosauridae (represented by a large sized Sauropod, probably Hypselosaurus); Iguanodontidae (afI. Rhabdodon, medium sized Omithopod); and Hadrosauridae (Ortbomerus, small sized). 3.° Dinosaur's footprints, not very well preserved, medium and large sized, attributable to biped Omithopod. The fauna remains were always found unconnected, scattered all over large areas and with no signs of depredation. The sort of materials found reveal a certain transport which caused a selective action over the remains. Later, the efIects of the orogenic processes suffered by this area in the Tertiary period would combine with this transport.El estudio de gran parte del material hallado en los trabajos de excavación realizados por un equipo del «Institut de Paleontología de Sabadell» y otros paleontólogos de las Universidades de Madrid y Bellaterra, en la cuenca de Tremp (Maastrichtiense), durante los años 1984 y 1985, ha permitido reconocer: 1.º Un crocodílido de gran talla, atribuible a un animal adulto de la familia Alligatoridae, comparable a Crocodilus affluvelensis. 2.° Restos de dinosaurios que se han atribuido a tres familias: Atlantosauridae (representada por un saurópodo de gran talla, probablemente Hypselosaurus); Iguanodontidae (afI. Rhabdodon, ornitópodo de talla media), y Hadrosauridae (Ortbomerus, de talla pequeña). 3.° Icnitas de dinosaurios, bastante mal conservadas, de tamaño medio y grande, atribuibles a omitópodos bípedos. Los restos faunísticos han sido hallados siempre inconexos, esparcidos en extensas superficies y sin señales de depredación. El tipo de material hallado indica, en principio, un cierto transporte, el cual ejerció una acción selectiva sobre los restos. Posteriormente, a este transporte se unirían los efectos de los procesos orogénicos que afectaron la zona durante el Terciario

    It Is Not Pneumocystis jiroveci (PCP), It Is Cyclophosphamide-Induced Pneumonitis

    Cyclophosphamide (CYC) is an immunosuppressive medication used to treat life-threatening complications of various rheumatic diseases like vasculitis and systemic lupus erythematosus. A rare side effect of this medication is pneumonitis, which occurs in less than 1% of patients. We describe a case of an 83-year-old woman with a past medical history of microscopic polyangiitis, who presented with progressive dyspnea at rest, exacerbated on exertion, and associated with orthopnea that was attributed to CYC-induced pneumonitis. Three months before this presentation, the patient was diagnosed with antineutrophil cytoplasmic antibodies (ANCA)-positive pauci-immune crescentic and necrotizing glomerulonephritis and started on CYC. On admission, a computed tomography (CT) chest showed worsening bilateral ground-glass opacities in a mosaic distribution and inter and intralobular septal thickening, not present on the CT performed three months prior. The patient underwent an extensive workup, which included an echocardiogram, bronchoscopy with bronchoalveolar lavage, and viral respiratory panel to rule out infectious and cardiac pathologies. She was started on empiric treatment with antibiotics and diuretics, however, despite these interventions, she continued with respiratory distress. A multidisciplinary team convened, and the diagnosis of CYC-induced lung injury was entertained. The CYC was discontinued, and the patient was started on prednisone with significant improvement in symptoms. This case highlights the importance of recognizing CYC as a rare cause of interstitial pneumonitis. When considering CYC-induced lung toxicity, other etiologies, such as opportunistic infections, cardiac etiologies, and diffuse alveolar hemorrhage, should be ruled out

    The aim of this paper is to complete the study of the Dinosaur fauna of the syncline of Galve (Teruel, Spain). Most of the outcrops are Early Barremian in age. Nevertheless, the outcrop called Las Zabacheras could be Hauterivian and El Pelejón Hauterivian-Early Barremian in age. Theropod Dinosaurs are poorly represented. Three vertebral centra are described. They are identified as Theropoda indet. The several outcrops of Galve have yielded four forms of Sauropods. Three of them (cf. Astrodon sp., Camarasauridae indet., form A, Camarasauridae indet., form B) have been identified based on isolated teeth. The Sauropod from Las Zabacheras (Lapparent, 1960; Sanz, 1982) has been proposed as a new taxon, Aragosaurus ischiaticus n. gen. et n. sp. The material which the new taxon is based on are the bones studied by Lapparent (Museo de la Diputación de Teruel) and new ones: caudal vertebrae, chevrones, seapula, ilium, femur and autopodial material. After a research on evolutive polarity of some traits within the Sauropoda, the apomorphic character-states which define the new taxon are as follows: First caudal vertebrae with a great transversal development of the neuroapophysis (club-like), seapular blade terminally expansioned, with an intermediate development (for example between Cetiosaurs and Brachiosaurus or Rebbachisaurus). Great dorso-ventral development (acromio-glenoideus) of the anterior seapular zone (ratio miminal width of the seapular blade/maximal acromio-glenoideus height of 0.27). lliac process of ischium well developed. Pubic process of ischium with great dorso-ventral development (ratio antero-posterior length of this process/lenght of ischiadic contact with pubis, 0.63). Ischiadic process of ischium with a conspicuous final expansion. Lenght ratio humerus/femur 0.82. Lateral bulge just distal to the femoral greater trochanter. Medial condyle of femur relatively developed (ratio maximal antero-posterior diameter of medial condyle/maximal transversal distal femoral width of 0.77). The Aragosaurus taxonomic status is proposed within the family Camarasauridae (sensu Steel, 1970). The Ornithopoda described in this paper mainly belong to the family Hypsilophodontidae, except an isolated tooth identified as Ornithopoda indet. A proximal fragment of a left femur is identified as cf. Valdosaurus sp. Hypsilopbodon foxii has been identified based on a left femur and an ilium.El objetivo principal del presente trabajo ha sido completar el estudio de la fauna de dinosaurios del sinclinal de Galve, de edad mayoritariamente barremiense inferior, aunque el yacimiento de Las Zabacheras puede tener una edad Hauteriviense y el Pelejón Hauteriviense-Barremiense inferior. Los Terópodos están pobremente representados, describiéndose tres centros vertebrales que son identificados como Theropoda indet. Cuatro formas diferentes de Saurópodos han sido identificadas en los diferentes yacimientos de Galve. Tres de ellas (cf. Astrodon sp.; Camarasauridae indet., forma A; Camarasauridae indet., forma B) tan sólo mediante piezas dentarias aisladas. El Saurópodo de Las Zabacheras (Lapparent, 1960; Sanz, 1982) ha sido propuesto como un nuevo taxon, Aragosaurus ischiaticus n. gen. et n. sp. Dicho material consta de diversos restos apendiculares y pélvicos estudiados por Lapparent y depositados en el Museo de la Diputación de Teruel y nuevos elementos consistentes en diversas vértebras caudales, chevrones, escápula, isquion, fémur y restos autopodiales. Las apomorfias más relevantes que definen al nuevo taxon son su relación estilopodial (longitud húmero/fémur) de 0,82, el gran desarrollo relativo dorso-ventral del contorno de contacto con el pubis del proceso pubiano del isquion y la aparición de neuroapáfisis «mazudas» en las primeras vértebras caudales. El enclave taxonómico de Aragosaurus se propone dentro de la familia Camarasauridae (sensu Steel, 1970). Los Ornitópodos descritos en este trabajo pertenecen a la familia Hypsilophodontidae, excepto una pieza dentaria aislada identificada como Ornithopoda indet. Un fragmento proximal de un fémur izquierdo es identificado como cf. Valdosaurus sp. La especie Hypsilophodon foxii ha sido identificada en base a un fémur izquierdo y un íleon
