Efeito hormese de glyphosate em feijoeiro
Silva, Juliano Costa da;Arf, Orivaldo;Gerlach, Gustavo Antonio Xavier;Kuryiama, Clarice Sayumi;Rodrigues, Ricardo Antonio Ferreira;
Pesquisa Agropecuária Tropical , 2012, DOI: 10.1590/S1983-40632012000300008
Abstract: although being well-known, the hormesis effect has not yet a defined practical application on the development of agricultural technology. thus, this study was carried out in selvíria, mato grosso do sul state, brazil, in order to evaluate the effect of glyphosate applied at low doses (0 g ha-1, 10 g ha-1, 20 g ha-1, 30 g ha-1 and 40 g ha-1 of active ingredient) on the development and yield of bean cultivars (carioca precoce - type i, juriti - type ii and pérola - type iii), irrigated by aspersion, in the autumn/winter of 2009 and 2010. the experimental design was randomized blocks, with 15 treatments arranged in a 5x3 factorial scheme and four replications. it was possible to conclude that the 100 grains mass decreased when submitted to higher glyphosate sub doses, and that the application of glyphosate sub doses did not affect the common bean yield, when the three cultivars were evaluated altogether, however, when each cultivar was individually analyzed, an increase of up to 10% in yield was observed for the juriti cultivar.
Flowering Ecology of the Species of the Genus Hypoxidia (Hypoxidaceae: Asparagales)
Justin Gerlach
Journal of Botany , 2011, DOI: 10.1155/2011/104736
Abstract: Hypoxidia (Hypoxidaceae) is endemic to the Seychelles islands. The two species H. rhizophylla and H. maheensis have rarely been studied. The first studies of floral ecology are described based on 19 years of observations of cultivated (1992–1994) and wild (1998–2011) plants of H. rhizophylla and a single flowering event of cultivated H. maheensis. In H. rhizophylla, heavy rainfall acts as a trigger to flowering, with flowers opening 14 days after heavy rain. This can occur in any month and local rainfall can act as a trigger even in generally dry conditions. Flowers are only open for a few hours, usually in the morning. Pollinators have not been identified but only one specie has been seen visiting flowers regularly; the fly Dichaetomyia fasciculifera (Muscidae) is common on Silhouette island where 12% of flowers are pollinated but very scarce on Mahé where fruiting of H. rhizophylla is rarely recorded. Low rates of pollination and limited dispersal is thought to result in effective isolation of most populations which probably mainly reproduce clonally. Clarification of this requires further research into genetic structuring of the populations. 1. Introduction Hypoxidia is an isolated genus of the family Hypoxidaceae. It comprises two species, restricted to the Seychelles islands and forms a monophyletic Seychelles clade with the species “Curucligo” seychellensis [1]. The Hypoxidaceae have largely been overlooked in ecological studies due to the relatively small size and inconspicuous nature of most of the species. The Seychelles Hypoxidaceae are unusual in that they can be argued to form a major part of the forest ecosystems, being among the few herbaceous plants to be found in the closed woodlands of the larger Seychelles islands. Hypoxidia rhizophylla (Baker) F. Friedmann is the most widespread of the Seychelles Hypoxidaceae, being recorded from Mahé, Silhouette, Praslin, La Digue, Curieuse, and Felicite [2, 3]. On these islands it is rarely found below 150?m?a.s.l. but can be found from sea level to 900?m?a.s.l. (personal observation). In contrast, H. maheensis F. Friedmann is known only from most forests above 300?m on Mahé island. The two species differ in floral morphology and in some vegetative characters. H. rhizophylla is highly variable in leaf shape and size but always shows the ability to reproduce with epiphyllous buds. As a result it frequently forms what are probably clonal clumps. H. maheensis does not appear to form epiphyllous buds and has lower density populations. A high degree of geographical variation in floral characters has been
Risk management in patients with severe acute pancreatitis
Herwig Gerlach
Critical Care , 2004, DOI: 10.1186/cc3007
Abstract: Severe acute pancreatitis (SAP) can progress to a critical condition within a few hours or days after the onset of symptoms. Particularly during the early course of the disease, patients are at high risk for developing infections with subsequent multiple organ dysfunction syndrome. Therefore, early surgical intervention has been favoured, although evidence-based data are lacking. In this issue of Critical Care, De Waele and coworkers [1] present findings from a critical review conducted over nearly a decade. In contrast to many prior recommendations, the authors could not find any significant association between the timing of surgery and patient outcomes. Moreover, they identified patient age, severity of organ dysfunction at the time of surgery, and the presence of sterile necrosis as the main risk factors, and concluded that an early surgical intervention is not justified in the absence of proven infection when necrosis is detected after computed tomography (CT) scan [1]. These important findings once again raise the issue of risk assessment in the individual patient with SAP.A major problem in the treatment of patients with SAP is the lack of randomized trials. Recently, King and coworkers [2] reported results from the first pan-European survey conducted among specialists in hepato-pancreato-biliary surgery of surgical strategies for management of SAP, with the aim being to highlight areas of discordance and thus provide a rational focus for future research. A questionnaire survey of 866 surgeons was undertaken, and the response rate was 38%. Severity stratification was used by 324 respondents (99%), with the Ranson score being the most popular. Antibiotic prophylaxis was utilized by 73%, and fine needle aspiration biopsy (FNAB) was undertaken by 53% of respondents. Furthermore, the results show that there were further aspects of practice that were concordant among surgeons, such as use of early CT and agreement that infected necrosis should be treated surgically
An "encyclopaedia" for anaesthesia and intensive care medicine: is it possible?
Herwig Gerlach
Critical Care , 2005, DOI: 10.1186/cc3056
Abstract: As one leafs through the book, the high quality of the 166 figures and 35 tables is striking. Combining due simplicity and necessary accuracy, the figures present elementary facts about basic anatomy, physiology, pharmacology and specific topics. Within the text, numerous cross-references are of considerable help to the reader in finding related topics and important basic information. The short historical reviews support a better understanding of the complex background. Another feature of the book is the parallelism of scientific basics and practical issues; for example, cartoons and precise descriptions of a chest drainage system or symbols of electrical equipment are presented with the same care as complex plans of the lumbar plexus or the anatomy of the mediastinal tract. This kind of high-quality work has clearly required years of careful analysis, and I am sure that this will be valued by a broad readership.Some criticisms, however, have to be raised. After thorough review, this book refers predominantly to topics about anaesthesia, whereas intensive care medicine is not always presented in an updated manner. Let us take some examples. The management of severe sepsis and septic shock is not in accordance with current recommendations. Very often, the authors refer to recent (2003) review articles dealing with pathophysiological aspects of the disease. In contrast, none of the major randomized clinical trials from 2001 and 2002, which are part of current guidelines, are cited. Time cannot be the problem, because more recent publications are mentioned. Surprisingly, terms such as 'antithrombin' and 'immunonutrition' are not mentioned. Furthermore, there is no statement regarding immunoglobulins, and no clear recommendation for catecholamine therapy in septic patients is to be found. Finally, recommendations for preventive measures against ventilator-associated pneumonia (such as daily sedation vacation, head-up positioning and low tidal volume) are not mentioned.

Greenscape as Screenscape - The Cinematic Urban Garden
Nina Gerlach
The Brock Review , 2008,
Abstract: The relationship between city and garden appears in many feature films in order to visualize narrative dualisms. In particular, the character of the border - as a fundamental medial characteristic of gardens - determines the meaning of the represented space. According to the Western representation of ideal places and the historically-developed antagonism of city and garden, the border defines the latter as the diametrically opposed utopian antithesis to urban life. This antagonism is used, for example, in The Garden of the Finzi-Continis (1970) in the political context of World War II, or as in Being There (1979), embedded in a philosophical discourse centered on Voltaire and Sartre.

Chroniques Yéménites , 2003,
Abstract: Dans l’étude des relations interculturelles entre l’Arabie du Sud et la région syro-palestinienne d’une part, la Mésopotamie d’autre part, l’examen du tracé des voies commerciales et l’exploitation des sources assyriennes mentionnant les royaumes sudarabiques ou leurs monarques apparaissaient jusqu’ici comme essentiels. Par ailleurs, une étude approfondie des écrits des auteurs classiques a également été entreprise. Hérodote (Histoire, III, 107), Strabon (Géographie, XVI, 765 sq.) et Pline l’...
