Marbofloxacin achieves high concentration in pig tonsils according to a dose dependent fashion

The penetration of marbofloxacin into tonsils was assessed in fattening pigs. Two different dosages were used to treat the animals: 2 mg/kg b.w. every 24 hours during 3 days (P1 group) and 4 mg/kg b.w. every 48 hours two times (P2 group. A ratio between the mean tonsillar concentration of marbofloxacin for both doses 24 hours after the last administration (0.5 and 0.7 µgr/mL) and its MIC90 for APP (0.03 µgr/mL) was calculated. These Ratio values were 16.6 and 23.3 for P1 and P2 group.

IFRS adoption in Europe: the case of Germany

From 2005 onwards, consolidated financial statements of listed European companies will have to comply with IFRS (IAS). Many German companies began adopting those standards in the 1990s, on a voluntary basis, because of their need to access international capital funding. Spanish companies, by contrast, are not permitted to adopt IFRS before 2005. This paper has two purposes: first, it analyses the financial impact of initial IFRS adoption on the statement of changes in equity and the income statement of individual German companies. Second, and taking into account the German experience, it focuses on the expected impacts on a sample of listed Spanish companies in two industrial sectors: chemical-pharmaceutical and fashion. Our analysis of German companies comprised all non-financial DAX groups applying IFRS plus additional listed companies in the two selected industrial sectors identified above. The impact of initial adoption of IFRS on German companies was, both individually and overall, very significant. The analysis suggests that the expected impact on Spanish companies is likely to be significant but to a lesser degree than in respect of the German companies in the study.

The Rise of democracy in Europe and the fight against mass poverty in Latin America: the implications for marxist thought of some recent mainstream papers

Recently a number of mainstream papers have treated the rise of democracy in 19th century Europe and its instability in Latin America in an eminently Marxist fashion. This paper sets out their implications for Marxist thought. With respect to Europe, Marx's emphasis on political action backed by the threat of violence is vindicated but his justification for socialism is not. With respect to Latin America, the unequal distribution of wealth is the cause of political instability that is, in turn, the root cause of mass poverty. In addition it is possible to explain some of the paradoxical characteristics of neo-liberalism and to make a weak argument for socialism in spite of its rejection in Europe.

Marxian insights from the mainstream

Starting in 1999 a group of papers have appeared in mainstream journals that treat of the relation between capitalism and democracy in an eminently Marxian fashion. These analyses bear on a number of papers published mainly in S&S, specifically those of Castañada, Ellman, Harnacker, Nimtz and Petras. This paper provides résumés of all of these works and then sets out the implications of the mainstream papers for the left wing ones. It concludes by emphasising the importance for the left of the mainstream results.

Where Has the Old Debate Gone? Realism, Institutionalism, and IR Theory

This paper resorts to the contribution of the science philosopher Gerald Holton to map some of the IR arguments and debates in an unconventional and more insightful way. From this starting point, it is sustained that the formerly all-pervading neorealism-neoinstitutionalism debate has lost its appeal and is attracting less and less interest among scholars. It does not structure the approach of the theoretically-oriented authors any more; at least, not with the habitual intensity. More specifically, we defend that the neo-neo rapprochement, even if it could have demonstrated that international cooperation is possible and relevant in a Realist world, it has also impoverished theoretical debate by hiding some of the most significant issues that preoccupied classical transnationalists. Hence, some authors appear to be trying to rescue some of these arguments in an analytical and systematic fashion, opening up a theoretical querelle that may be the next one to pay attention to.

Gestión de productos de una empresa dedicada a la moda

Aquesta memòria ha estat realitzada per donar a conèixer el project que du per títol "Gestió de productes d'una empresa dedicada a la moda". Aquesta aplicació intentarà introduir en el mercat una solució per a les petites empreses que volen fer-se un lloc en el món de la moda i que necessiten un programari per poder gestionar les seves botigues. En aquest sector existeixen petits empresaris que van començar realitzant les peces de roba a les seves fàbriques i que han decidit fer petites col·leccions i posar-les a la venda al detall, a les seves propies franquícies. Aquesta aplicació mostra un mòdul d'un projecte molt més gran. El mòdul s'encarrega de la gestió dels articles creats a fàbrica, per poder distribuir-los entre les botigues. Un possible segon mòdul es dedicaria a la gestió de les vendes a les botigues.

Reactive and proactive approaches for introspective CBR

This work investigates applying introspective reasoning to improve the performance of Case-Based Reasoning (CBR) systems, in both reactive and proactive fashion, by guiding learning to improve how a CBR system applies its cases and by identifying possible future system deficiencies. First we present our reactive approach, a new introspective reasoning model which enables CBR systems to autonomously learn to improve multiple facets of their reasoning processes in response to poor quality solutions. We illustrate our model’s benefits with experimental results from tests in an industrial design application. Then as for our proactive approach, we introduce a novel method for identifying regions in a case-base where the system gives low confidence solutions to possible future problems. Experimentation is provided for Zoology and Robo-Soccer domains and we argue how encountered regions of dubiosity help us to analyze the case-bases of a given CBR system.

A Comparison of the poverty impact of transfers, taxes and market income across five OECD Countries

This paper compares the poverty reduction impact of income sources, taxes and transfers across five OECD countries. Since the estimation of that impact can depend on the order in which the various income sources are introduced into the analysis, it is done by using the Shapley value. Estimates of the poverty reduction impact are presented in a normalized and un-normalized fashion, in order to take into into account the total as well as the per dollar impacts. The methodology is applied to data from the Luxembourg Income Study (LIS) database.

Estudi ambiental del Centre Esportiu Puigverd: aigua, residus i característiques físiques

El medi ambient està creixent i adquirint actualment una importància fins ara mai vista. La societat reconeix el medi ambient com un factor de benestar social i personal, i alhora una característica de modernitat. En aquest estudi s’analitzen tots els factors ambientals presents en l’activitat quotidiana d’un centre esportiu. El centre escollit es troba situat en el municipi de Castellar del Vallès, a la comarca del Vallès Occidental, província de Barcelona. Aquest centre construït fa 17 anys per la demanda continua dels habitants del poble i per les pressions dels nuclis urbans pròxims, ha sofert uns canvis que actualment encara estan presents. Els objectius de l’estudi són la descripció, l’anàlisi i el tractament de la gestió actual del centre envers els recursos utilitzats. L’aigua, els residus i per últim les propietats físiques de l’edificació, com a innovació en aquesta tipologia d’estudis. L’anàlisi i tractament d’aquests, permet conèixer els punts forts i febles del centre. Les flaqueses observades afecten majoritàriament als factors ambientals. Conseqüentment, es dissenyen unes propostes de millora per tal de poder minimitzar els impactes soferts i redireccionar la gestió ambiental del centre, afrontant així un futur amb un desenvolupament sostenible.

Evaluación de un nuevo método de sutura para la cirugía endoscopica transluminal a través de orificios naturales en un modelo animal

Natural Orifice Transluminal Endoscopic Surgery (NOTES) is a novel, potentially less invasive alternative to laparoscopic surgery. However, the problems of transluminal access and closure represent significant obstacles to its successful introduction in humans. Objective: to evaluate the feasibility and safety of a novel device designed for transluminal access and closure in a survival porcine model. Subjects: Four adult female Yorkshire pigs were used in the study. Interventions: While under general anesthesia, the animals were prepared with multiple tap water enemas followed by instillation of an antibiotic suspension and povidone-iodine lavage. At a distance of 15 to 20 cm from the anus, the prototype device (LSI Solutions, Victor, NY, USA) deployed a circumscribing purse-string suture around the planned incision site and subsequently used a blade mechanism to create a 2.5-cm linear incision. The transcolonic incision was then closed by cinching and securing the purse-string suture with a titanium knot by use of a separate hand-activated suture-locking device. Main Outcome Measurements: The animals were monitored daily for signs of peritonitis and sepsis and were survived for 14 days. The peritoneal cavity was examined for peritonitis, and the colonic incision site was examined for wound dehiscence, pericolic abscess formation, and gross adhesions. Tissue samples from both incisional and random peritoneal sites were obtained for histologic examination. Results: Transcolonic incision and closure were successful in all 4 animals. The device performed in a rapid and reproducible fashion. All animals recovered without septic complications. At necropsy, there was no evidence of peritonitis, abscesses, or wound dehiscence. Salpingocolonic and colovesicular adhesions were noted in 3 of 4 animals. Histologic examination revealed microabscesses at the incision site in all animals. Conclusions: The prototype incision and closure device represents a promising solution to the problems of transluminal access for NOTES. The presence of incision-related adhesions and microabscesses signal the need for further refinement in aseptic technique. 

El comportamiento penalmente relevante en el delito de defraudación tributaria: una propuesta político-criminal

El sistema tributario es fundamental en el Estado social y democrático de Derecho, pues el ejercicio y efectivo disfrute de muchos derechos fundamentales depende del correcto funcionamiento de la actividad tributaria. Además de esto, la situación económica actual demanda una adecuada política en contra del fraude tributario, lo que necesariamente implica analizar si el modelo penal vigente es el más adecuado para enfrentar el fraude fiscal. Teniendo en cuenta que muchas de las características de la criminalidad tributaria no son exclusivas de un país, pues ésta trasciende habitualmente las fronteras de los países por medio del recurso a empresas multinacionales o la localización de empresas en “paraísos fiscales”, el análisis del fraude tributario no debe limitarse al examen jurídico del modelo legislativo español, debiendo trascender a un estudio de política criminal que vincula consideraciones criminológicas y jurídicas. En consecuencia, en esta investigación se propone un análisis que no se reduce a los debates exclusivamente jurídicos. Se busca, además, efectuar un examen que tenga por fundamento una perspectiva criminológica y de Law in action a fin de evaluar críticamente la respuesta a la criminalidad tributaria por parte del modelo de regulación penal vigente en España. Esta orientación permitirá una más amplia comprensión del fenómeno de la criminalidad tributaria, así como de las categorías jurídicas adecuadas político criminalmente para su prevención. Este estudio interdisciplinario nos conducirá, al final de la investigación, tanto a proponer la interpretación del modelo de legislación penal vigente, como una reforma al mismo que pretenda solucionar algunos de los problemas de prevención que a lo largo de la investigación se señalan.

Correction of shading effects in vision-based UUV localization

This paper describes the improvements achieved in our mosaicking system to assist unmanned underwater vehicle navigation. A major advance has been attained in the processing of images of the ocean floor when light absorption effects are evident. Due to the absorption of natural light, underwater vehicles often require artificial light sources attached to them to provide the adequate illumination for processing underwater images. Unfortunately, these flashlights tend to illuminate the scene in a nonuniform fashion. In this paper a technique to correct non-uniform lighting is proposed. The acquired frames are compensated through a point-by-point division of the image by an estimation of the illumination field. Then, the gray-levels of the obtained image remapped to enhance image contrast. Experiments with real images are presented

On the way to solve lighting problems in underwater imaging

A major obstacle to processing images of the ocean floor comes from the absorption and scattering effects of the light in the aquatic environment. Due to the absorption of the natural light, underwater vehicles often require artificial light sources attached to them to provide the adequate illumination. Unfortunately, these flashlights tend to illuminate the scene in a nonuniform fashion, and, as the vehicle moves, induce shadows in the scene. For this reason, the first step towards application of standard computer vision techniques to underwater imaging requires dealing first with these lighting problems. This paper analyses and compares existing methodologies to deal with low-contrast, nonuniform illumination in underwater image sequences. The reviewed techniques include: (i) study of the illumination-reflectance model, (ii) local histogram equalization, (iii) homomorphic filtering, and, (iv) subtraction of the illumination field. Several experiments on real data have been conducted to compare the different approaches

Importació d'obres artístiques dels Països Baixos del Sud a Catalunya durant els segles XV i primera meitat del XVI

Durant els segles XV i primera meitat del XVI, tota mena de productes de luxe eren exportats des dels Països Baixos del sud a tota Europa, moda fomentada pels ducs de Borgonya, que governaven el territori. Malgrat el major número d’estudis sobre les relacions entre la Corona de Castella i Flandes a finals de l’Edat Mitjana, i les més nombroses peces flamenques conservades en aquesta regió veïna, també la Corona d’Aragó mantenia intenses relacions comercials amb els Països Baixos del sud, essent la colònia de mercaders catalans de les primeres en establir-se a Bruges, principal port d’exportació a l’època. És nombrosa la documentació referida a naus catalanes viatjant cap al nord, així com als privilegis de què gaudia aquesta colònia de mercaders. Un bon grapat de peces d’aquesta procedència es conserven a museus i institucions locals. Malgrat que de moltes no se’n coneix el moment d’arribada, d’altres es troben ben documentades o se’n pot deduïr la seva presència a Catalunya des de finals de l’Edat Mitjana, conformant un farcit catàleg. D’altra banda, la documentació d’arxiu ens proporciona valuoses notícies sobre la gran quantitat de peces flamenques avui desaparegudes però que haurien existit a l’època, evidenciant que el que avui ens resta no és més que una molt petita porció del que hauria estat a finals de l’Edat Mitjana, i ens permet acostar-nos a una visió de la societat i els seus gustos més propera a la realitat de l’època, posant de manifest que la moda flamenca arrelaria intensament a Catalunya.

When to carry eccentric products? Optimal retail assortment under consumer returns

To understand whether retailers should consider consumer returns when merchandising, we study howthe optimal assortment of a price-taking retailer is influenced by its return policy. The retailer selects itsassortment from an exogenous set of horizontally differentiated products. Consumers make purchase andkeep/return decisions in nested multinomial logit fashion. Our main finding is that the optimal assortmenthas a counterintuitive structure for relatively strict return policies: It is optimal to offer a mix of the mostpopular and most eccentric products when the refund amount is sufficiently low, which can be viewed asa form of risk sharing between the retailer and consumers. In contrast, if the refund is sufficiently high, orwhen returns are disallowed, optimal assortment is composed of only the most popular products (a commonfinding in the literature). We provide preliminary empirical evidence for one of the key drivers of our results:more eccentric products have higher probability of return conditional on purchase. In light of our analyticalfindings and managerial insights, we conclude that retailers should take their return policies into accountwhen merchandising.
