Análisis de los exponentes de Lyapunov asociados al funcionamiento de un destilador

El carácter caótico de la intensificación de la transferencia térmica convectiva en el interior de un destilador no puede determinarse a partir de un único indicador. En trabajos previos se analizaron las series temporales de h, el espectro de Fourier y su tasa de crecimiento. En el presente trabajo se analizan los exponentes de Lyapunov de h así como los de las series temporales medidas de temperaturas involucradas en su cálculo. Los resultados muestran que algunas series de medidas de h presentan caos y otras no, mientras que las medidas de temperatura muestran comportamiento caótico en todas las series de medida.The chaotic character of the convective heat transfer enhancement inside a still cannot be stated from a unique indicator. In previous papers time series, the Fourier spectrum and the growing rate of h were performed. In the present work Lyapunov exponents of h are calculated, as well as those of the time series of measured temperatures involved in its calculation. The results show that some series of h present chaos and others not, while all the temperatures measurements show a chaotic behaviour.Asociación Argentina de Energías Renovables y Medio Ambiente (ASADES

Primary leiomyosarcoma of the right atrium: a case report and literature update

Leiomyosarcoma of the right atrium is a very rare cardiac tumor. Various combinations of treatments including resection or transplant surgery and Chemotherapy have been advocated. We report a case of a man who presented with pulmonary embolism secondary to right atrial leiomyosarcoma. He was managed by excision of the tumor and reconstruction of the right atrium with autologous pericardium. Postoperatively tumor dissemination was controlled with adjuvant chemotherapy

Formation of a ZnS Zn S,O bilayer buffer on CuInS2 thin film solar cell absorbers by chemical bath deposition

The application of Zn compounds as buffer layers was recently extended to wide gap CuInS2 CIS based thin film solar cells. Using a new chemical deposition route for the buffer preparation aiming at the deposition of a single layer, nominal ZnS buffer without the need for any toxic reactants such as, e.g. hydrazine, has helped to achieve a similar efficiency as respective CdS buffered reference devices. In order to shed light on the differences of other Zn compound buffers deposited in conventional chemical baths CBD compared to the buffer layers deposited by this alternative CBD process, the composition of the deposited buffers was investigated by x ray excited Auger electron and x ray photoelectron spectroscopy to potentially clarify their superiority in terms of device performance. We have found that in the early stages of this alternative CBD process a thin ZnS layer is formed on the CIS, whereas in the second half of the CBD the growth rate is greatly increased and Zn S,O with a ZnS ZnS ZnO ratio of approx. 80 is deposited. Thus, a ZnS Zn S,O bi layer buffer is deposited on the CIS thin film solar cell absorbers by the alternative chemical deposition route used in this investigation. No major changes of these findings after a postannealing of the buffer CIS sample series and re characterization could be identified

Ultrasound-guided thrombin injection for the treatment of an iatrogenic hepatic artery pseudoaneurysm: a case report

<p>Abstract</p> <p>Introduction</p> <p>Percutaneous transhepatic portal embolization is often performed to expand the indications for hepatic resection. Various etiologies of hepatic artery pseudoaneurysm have been reported, but regardless of the etiology, hepatic artery pseudoaneurysm is usually managed with an endovascular approach or open surgery, depending on the location and clinical symptomatology. However, it is difficult to manage hepatic artery pseudoaneurysm after percutaneous transhepatic portal embolization, since embolization of the hepatic artery may cause hepatic infarction</p> <p>Case presentation</p> <p>A 58-year-old Japanese man with hilar bile duct cancer underwent percutaneous transhepatic portal embolization to expand the indication for hepatic resection. Two days after percutaneous transhepatic portal embolization, our patient suddenly complained of abdominal pain. Contrast-enhanced computed tomography confirmed a pseudoaneurysm arising from a segmental branch of his right hepatic artery. Since embolization of the hepatic arterial branches may cause hepatic infarction, ultrasound-guided thrombin injection therapy was successfully performed for the pseudoaneurysm.</p> <p>Conclusion</p> <p>We performed a thrombin injection instead of arterial embolization to avoid hepatic infarction. The rationale of this choice may be insufficient. However, ultrasound-guided percutaneous thrombin injection therapy may be considered as an alternative to percutaneous transarterial embolization or surgical intervention for an iatrogenic hepatic artery pseudoaneurysm.</p

Immunologically reactive M. leprae antigens with relevance to diagnosis and vaccine development

<p>Abstract</p> <p>Background</p> <p>Leprosy is a chronic infectious disease caused by <it>Mycobacterium leprae </it>that can manifest a wide variety of immunological and clinical outcomes ranging from potent humoral responses among borderline lepromatous (BL) and lepromatous (LL) patients to strong cellular responses among tuberculoid (TT) and borderline tuberculoid (BT) patients. Until recently, relatively little has been known about the immune responses to individual proteins of <it>M. leprae </it>recognized during leprosy.</p> <p>Methods</p> <p>The immune reactivity to a panel of 33 <it>M. leprae </it>recombinant proteins was evaluated among leprosy patients and controls from a high endemic area for leprosy (Goiania/GO, Central Brazil). Serum IgG responses were measured by ELISA (45 participants/group) and T cell responses (20 participants/group) were evaluated by IFN-gamma production in 24 hours whole blood cultures with antigen (whole blood assay-WBA). Study groups were newly diagnosed, untreated TT/BT and BL/LL leprosy patients classified by Ridley Jopling criteria and household contacts of BL/LL patients (HHC). Control groups were HIV-1 negative pulmonary tuberculosis patients (TB) and healthy individuals from the same endemic area (EC). In silico predictions indicated the level of identity of <it>M. leprae </it>proteins with homologues in other mycobacteria and the presence of T cell and B cell epitopes.</p> <p>Results</p> <p>Despite the prediction that all proteins would be reactive, 16 of 33 (48%) of the single proteins tested were immunogenic (recognized in WBA or ELISA) and seventeen were non-immunogenic (not recognized in either assay). Among the 16 immunogenic proteins, 9 were considered leprosy specific in WBA inducing cell-mediated IFN-gamma secretion from TT/BT patients and HHC. Three of these proteins were also leprosy specific in serology being recognized by serum IgG from LL/BL patients. Seven of the immunogenic proteins were not leprosy specific.</p> <p>Conclusions</p> <p>New <it>M. leprae </it>antigens recognized by antibody responses of BL/LL patients and cellular responses of TT/BT leprosy patients were identified. An improved serological diagnostic test for leprosy could be developed by incorporating these IgG-reactive antigens to the current PGL-I based tests. Moreover our data indicate that the WBA is a robust, relatively simple and user friendly format for a T cell based diagnostic test. The field use of these test formats in leprosy endemic countries could contribute to early leprosy diagnosis before the development of deformities and disabilities.</p

Water seepage beneath dams on soluble evaporite deposits: a laboratory and field study (Caspe Dam, Spain)

The paper presents analytical methods and results for assessing the variation in the concentration of sulphate (and other ions) over space and time in groundwater flowing through a soluble evaporite terrain beneath a dam. The influence of effective porosity, groundwater flow velocity and the specific rate of dissolution (K′) are considered. The theoretical analysis was tested in a scale model simulating a dam constructed on heavily karstified bedrock. A simple and useful method for assessing how much material is lost through dissolution and how the rate of dissolution changes over time is considered in the context of the Caspe Dam, Spain

An adaptive virtual reality system for the treatment of adjustment disorder and complicated grief: 1‐year follow‐up efficacy data

This is the pre-peer reviewed version of the following article: An adaptive virtual reality system for the treatment of adjustment disorder and complicated grief: 1‐year follow‐up efficacy data, which has been published in final form at https://doi.org/10.1002/cpp.2342. This article may be used for non-commercial purposes in accordance with Wiley Terms and Conditions for Use of Self-Archived Versions.Adjustment disorder (AD) and complicated grief (CG) are serious mental conditions that have a high prevalence and are associated with significant impairments in social and work functioning. Recently, these categories have been better specified in the new ICD‐11 proposal. Empirical research on the efficacy of treatments for these problems is scarce. This study aims to offer long‐term efficacy data from a between‐groups controlled study that compares two treatment conditions (AD‐protocol applied in a traditional way: N = 18 and the same protocol supported by virtual reality (VR); VR‐protocol applied in a traditional way: N = 18) and a waiting list (WL) control group (N = 18). Both treatment conditions resulted in statistically significant improvements on both primary and secondary outcome measures, with large effect sizes, and this improvement did not occur in the WL. These changes were maintained in both treatment conditions in the medium (6‐month) and long‐term (12‐month follow‐up). Larger effect sizes were achieved in the VR condition in the long term. Furthermore, clinically significant change estimations on the primary outcome measures showed an advantage for the VR condition This is the first controlled study to compare a traditional face‐to‐face protocol for the treatment of stress‐related disorders with the same protocol supported by VR and a WL control group
