A Guide to CoCo
No full textCoCo is a program for estimation, test and model search among hierarchical interaction models for large complete contingency tables. The name CoCo is derivated of "Co"mplete "Co"ntingency tables, since the initial program could only handle complete tables, but the program has been enhanced to handle incomplete tables. CoCo works especially efficiently on graphical models, and some of the commands are designed to handle graphical models.

The Effect of Morphometry, Land-Use and Lithology on Landslides Susceptibility: An Exploratory Analysis
No full textGIS features provide simple and useful tools for landslides susceptibility and hazard studies, allowing the identification and the quantification of predisposing factors, and their relative importance. In lithologically homogeneous areas, the most influent factor of landslides is slope morphometry, in particular inclination, height and form. Moreover, within a hydrographic basin, landslides are coupled with drainage network. In fact landslides density and drainage density are positively correlated. Furthermore, human activity strongly influences the development of landslides. In our previous works, we introduced MSI (Morphometric Slope Index) as general index for slope morphometry, combining the main linear and areal morphometric features (area, form, length, inclination, width). Its formula is: MSI=A3D/A2D·L·Rc (where A3D is the three-dimensional area of the slope, A2D is its plan area, L is the slope length and Rc is the circularity ratio). We tested MSI as driver of different erosion landforms, demonstrating its influence in determining, on the one hand, the development and the final arrangement of calanchi drainage network (the typical Italian badlands), and, on the other hand, the erosion processes within them, mainly gullies and landslides. The present study is an exploratory application of this index to landslides susceptibility, aimed to analyze the combined effect of slope morphometry (summarized in MSI), lithology and land-use on the distribution of landslides in small catchments. The study is located in the Italian periadriatic foredeep, in the Abruzzo Region. This study has reinforced our perspective about the validity of the application of the techniques of geomorphometric analysis to the landslides susceptibility. Especially we consider this approach an efficient tool to summarize different controlling factors
Changes in cortical excitability and blood lactate after a fatiguing hand-grip exercise
No full textExcitability of primary hand motor cortex (PHMC), evaluated with transcranial magnetic stimulation by using the "1mV resting motor threshold" method, and capillary blood lactate were measured at the end, as well as 5 and 10min after a fatiguing hand-grip exercise. The relation between blood lactate and the amplitudes of motor-evoked potentials showed a significant direct proportionality. Blood lactate seems to exert a protective role on PHMC against fatigue reduction during extremely intensive isometric exercises
Universalidade e singularidades do espaço transitório: um estudo a partir de quebradeiras de coco babaçu/MIQCB e trabalhadores rurais sem terra/MST no Maranhão (1990 - 2000)
No full textTese (doutorado) - Universidade Federal de Santa Catarina, Centro de Filosofia e Ciências Humanas. Programa de Pós-Graduação em GeografiaRecupera-se elementos do processo de universalização da produção da vida sob a mediação do capital, procurando apreender sobre a produção na sociedade burguesa, a produção da sociedade burguesa e como este processo gesta, nas suas entranhas, elementos de uma sociedade do vir-a-ser, isto é, da superação da sociedade burguesa. Dialogando com as formulações de Karl Marx e Friedrich Engels, procura-se entender explicitar como a universalidade da reprodução das relações burguesas de produção da existência social e humana materializa-se singularidades paradoxais nas diversas formações sócio-espaciais. Em particular estuda-se o processo de reprodução de quebradeiras de coco babaçu/MIQCB e de trabalhadores rurais sem terra/MST, na década de 1990, no Estado do Maranhão. Por estas mediações, percebe-se o escancaramento das dificuldades, quase impossibilidade, da (re)produção social e humana pelas relações capital # lucro, terra # renda fundiária ou trabalho # salário. Vive-se, portanto, um período de transição. Manifestam-se os dilemas entre a impossibilidade de retorno a formas pretéritas de produção da existência e as dificuldades de materialização do novo. A degeneração humana explicita-se como a forma mais visível dos homens reais se reproduzirem. Contraditoriamente, pode-se perceber experimentos que não podem ser interpretados como simples processo de reprodução da sociedade burguesa, estão para além delas. To recover elements from the process of universalization from the production of life under the mediation of the capital, searching to learn about production in the burgess society, the burgess society#s production and how this process is managed, deep inside, elements from a society still to be, that means, the overrun of the burgess society. Arguing with Karl Marx and Friedrich Engels thoughts, We try to understand and explain how the universality of reproduction from burgess relations of social and human existence production materializes paradoxal singularities inside many social-space structure formations. In particular studies the process of reproduction of quebradeiras of coco babaçu/MIQCB and the landless rural workers /MST, in the ninties, in the Maranhão State. Because of this mediations, we Perceive clearly the dificulties, almost impossible, of social and human (re)production through capital relations # profit, land # latifundium income or work # salary. So, we live a transition era. We express the dilemas between the impossibility of the return of the old structure production of existance and the difficulties of materialization of the new. The human deterioration explains itself as a more visible structure of the real men to reproduce. Contradictorily we are capable to perceive experiments which can not be interpretaded as a simple process of the burgess society reproduction, they are beyond that
Impact of COVID-19 on keratoconus patients waiting for corneal cross linking
No full textPurpose: Royal College of Ophthalmologist recent guidance recommended delaying cross-linking services during the COVID-19 pandemic. This study investigates the effects of such delays in the delivery of cross-linking services in patients with keratoconus progression. Methods: Retrospective observational study of 46 patients with keratoconus progression, whose cross-linking was delayed due to the COVID-19 pandemic. Demographic and clinical details were obtained from assessments on the day of listing, and subsequent review on the day of the procedure. Topographic indices included keratometry of the posterior and anterior corneal surface, maximum keratometry (Kmax), thinnest corneal thickness, ABCD progression and progression based on standard criteria recommendations (1.5 D Kmax & 20 microns thinning). Results: A total of 46 eyes were analysed with an average time between being listed for CXL and having the procedure done was 182 ± 65 days. The delay due to COVID-19 was of 3 months. In this time period they had a significant worsening of all keratometric indices and lost almost one line of visual acuity (0.19 ± 0.19 to 0.26 ± 0.18 LogMAR, p: 0.03). Thirty two eyes (70%) demonstrated progression in accordance with the ABCD progression criteria, while 18 eyes (39%) showed either an increase in Kmax of more than 1.5D or a thinning in corneal thickness of at least 20 μm. Conclusions: The treatment delay for the keratoconus patients caused further progression and vision worsening. We recommend that corneal collagen crosslinking needs to be considered as a high priority intervention
Análise da estrutura rítmica e melódica do coco de trupé na construção do processo composicional
No full textThis paper deals with the study of the samba de coco musical genre, which is practiced in Arcoverde, a town located in the backlands of the state of Pernambuco - Brazil. It aims to guide an investigation of the rhythmic beat and the melodic aspects performed in the sound of the coco de trupé, which is a subgenus of coco. Based on the musical characteristics produced, specifically by the group Samba de Coco Raízes de Arcoverde, we carried data on compositional elements used in their songs that were directed, by the author of this research, to his own musical compositions, intended for the protagonism of wind instruments in the sound of the coco de trupé, which were performed through the creation of an instrumental group in the form of a chamber group, whose name was called Maycon Nasário & o Coco Instrumental de Arcoverde. The results revealed that the rhythmic and melodic structures of samba de coco de trupé favored the compositional process for wind instruments through the
musical scales used in some songs by the group Raízes de Arcoverde, which were identified in my compositions for the instrumental group.Thus, several traditional characteristics, typical of this genre, were maintained, which presents a wealth of musical elements that can be explored by musicians and scholars in the research area of musicology and ethnomusicology, for a greater depth of the researched topic, as well as contributing to artistic manifestations of popular Brazilian music.Esta pesquisa versa sobre o estudo do gênero musical samba de coco, praticado no município de Arcoverde, localizada no sertão do estado de Pernambuco - Brasil, e objetivou pautar uma investigação da batida rítmica e dos aspectos melódicos executados na sonoridade do coco de trupé, este um subgênero do coco. A partir das características musicais produzidas, especificamente, pelo grupo Samba de Coco Raízes de Arcoverde, portamos os dados de elementos composicionais usados em suas canções que foram direcionadas, pelo autor desta
pesquisa para suas próprias composições musicais, destinadas ao protagonismo dos instrumentos de sopro no coco de trupé, que foram executadas através da criação de um grupo instrumental em forma de grupo de câmara, cujo nome foi denominado de Maycon Nasário & o Coco Instrumental de Arcoverde. Os resultados da pesquisa revelaram que as análises das estruturas rítmicas e melódicas do samba de coco de trupé favoreceram o processo composicional para os instrumentos de sopro através das escalas musicais usadas de algumas
canções do grupo Raízes de Arcoverde, que foram identificada em minhas composições para o grupo instrumental. Assim, foram mantidas várias características tradicionais, próprias desse gênero, que apresenta uma riqueza de elementos musicais podendo ser explorados por músicos e estudiosos da área de pesquisa da musicologia e etnomusicologia, para um maior aprofundamento do tema pesquisado, bem como contribuir para a manifestações artísticas de músicas brasileiras de origem populares
Recovery of damaged skeletal muscle in mdx mice through low-intensity endurance exercise
No full textThe lack of dystrophin in mdx mice leads to cycles of muscle degeneration and regeneration processes. Various strategies have been proposed in
order to reduce the muscle-wasting component of muscular dystrophy, including implementation of an exercise programme. The aim of this study was to examine how low-intensity endurance
exercise affects the degeneration-regeneration process in dystrophic muscle of male mdx mice. Mice were subjected to low-intensity endurance exercise by running on a motorized
Rota-Rod for 5 days/week for 6 weeks. Histomorphological analysis showed a signifi cant reduction of measured inflammatory-necrotic areas in both gastrocnemius and quadriceps muscle
of exercised mdx mice as compared to matched sedentary mdx mice. The degenerative-regenerative process was also evaluated by examining the protein levels of connexin 39 (Cx39), a specifi c gene expressed in injured muscles.
Cx39 was not detected in sedentary wild type mice, whereas it was found markedly increased in sedentary mdx mice, revealing active muscle
degeneration-regeneration process. These Cx39 protein levels were signifi cantly reduced in muscles of mdx mice exercised for 30 and 40 days, revealing together with histomorphological analysis a strong reduction of degeneration process in mice subjected to low-intensity endurance exercise. Muscles of exercised mdx mice did not
show significant changes in force and fatigue resistance as compared to sedentary mdx mice.
Overall in this study we found that specifi c lowintensity endurance exercise induces a beneficial effect probably by reducing the degeneration of
dystrophic muscle
