Abstract: two field experiments were conducted to confirm the etiological agent of the cassava 'brown leaf spot', to study the progress of the disease and to evaluate resistance, agronomic and nutritional traits of different cassava cultivars. the experiments were performed in rio de janeiro state, brazil. in the first experiment, six cassava cultivars (amarelinha, marcos op, iac-264, baiana, mantiqueira and sonora), were evaluated from february/1997 to june/1998. in the second experiment, performed from january to august/1999, the same cultivars, plus 'saracura', and 'rosada de sc' were evaluated, in a randomized complete block design, with three replicates. the intensity of the disease, initiated from natural infection, was quantified at seven and 15 days, when the severity and the incidence of injured leaves were considered. at harvest, the severity and incidence of injured leaves, defoliation rates and number of injured leaves were estimated. disease progress curves were built for the incidence and for severity data; the area under the curves was used to calculate the disease severity and infected leaf severity. there were differences among the cultivars in relation to brown leaf spot resistance, caused by cercosporidium henningsii. cultivar 'amarelinha' was the most susceptible, and 'baiana' and 'sonora' the most resistant. there were no differences between the cultivars in yield and root characteristics, except 'amarelinha' with higher root weight. there was a negative and significant correlation between the severity of the disease (expressed by the values of the area under the disease progress curve) and the number and weight of roots.

On the Expansion and Fate of the Universe  [PDF]
Aldo Bonasera
Journal of Modern Physics (JMP) , 2012, DOI: 10.4236/jmp.2012.311212
Abstract: The evolution of the universe from an initial dramatic event, the Big-Bang, is firmly established. Hubble’s law [1] (HL) connects the velocity of galactic objects and their relative distance: v(r) = Hr, where H is the Hubble constant. In this work we suggest that HL is not valid at large distances because of total energy conservation. We propose an expansion of the velocity in terms of their relative distance and produce a better fit to the available experimental data. Using a simple “dust” universe model, we can easily calculate under which conditions an (unstable) equilibrium state can be reached and we estimate the values of the matter present in the universe as well as the “dark energy”. Within the same formalism we can derive the “deceleration parameter”. We do not need to invoke any “dark energy”, its role being played by the kinetic correction. The resulting picture is that the universe might reach an unstable equilibrium state whose fate will be decided by fluctuations: either collapse or expand forever.
Sildenafil no tratamento da hipertens?o arterial pulmonar idiopática em crian?as e adolescentes
Oliveira, Edmundo Clarindo;Amaral, Carlos Faria Santos;
Jornal de Pediatria , 2005, DOI: 10.2223/JPED.1390
Abstract: objective: this study aims to provide data on the use of oral sildenafil in patients in new york heart association functional class iii or iv with severe idiopathic pulmonary arterial hypertension unresponsive to conventional therapy. method: in this series, six patients with idiopathic pulmonary arterial hypertension were prospectively treated with 2 to 8 mg of oral sildenafil in four to six doses a day. all pa-tients were submitted to physical examination, electrocardiogram and echocardiogram, chest computed tomography, ventilation and pulmonary perfusion scintigraphy, coagulation studies, and tests for collagen vascular disease, acquired immune deficiency syndrome and schisto-somiasis in order to rule out secondary causes of pulmonary arterial hypertension. all patients underwent cardiac catheterization for vasoreactivity tests using nitric oxide, o2 at 100% and oral nifedipine, and a 6-minute walking test was performed in those patients who were con-sidered able to exercise. results: all patients achieved a good therapeutic response, with improvement by at least one functional class, and presented an increase in systemic arterial oxygen saturation. five patients showed a decrease in the pulmonary systolic pressure to systemic systolic pres-sure ratio and improvement in the six-minute walking test. no major side effects were ob-served at 4 to 36 months of follow-up. one patient had sudden death after sildenafil had been withdrawn by mistake. conclusions: these data suggest that sildenafil may be useful in the manage-ment of idiopathic pulmonary arterial hypertension. patients should be advised against the withdrawal of sidenafil without medical supervision.

Online Educational Resources Regarding Cardiovascular Prevention  [PDF]
Aldo T. Marrocco
E-Health Telecommunication Systems and Networks (ETSN) , 2015, DOI: 10.4236/etsn.2015.41002
Abstract: This paper presents several informative and educational tools aimed to explain some mechanisms of Miocardial Infarction and Stroke, their risk factors and their prevention. Such educational and informative documents are in English and consist of texts, images, videos, animations and games. They are downloadable for free and can be used with the method considered by the teacher as most appropriate. Among the aims of the study is to provide information on the effects which some of our daily actions may have on the circulatory system. The pathological processes affecting blood vessels may start to develop during childhood or adolescence as a consequence of physical inactivity, unhealthy diet, smoking and alcohol abuse. Notoriously, unhealthy behaviours learned in early age are very likely to be continued in the adulthood. By the time they can lead to important car-diovascular risk factors, such as high blood pressure, overweight or obesity, raised blood sugars and lipids. Some of the documents presented in this manuscript suggest that complying with cardivascular prevention measures may also, at the same time, reduce the risk of other diseases.
Online Informative and Educational Resources on the Benefits That a Lifestyle Aimed at the Primary Prevention of Cancer May Also Provide for General Health  [PDF]

E-Health Telecommunication Systems and Networks (ETSN) , 2015, DOI: 10.4236/etsn.2015.42003
Abstract: To find stimuli for getting young students interested in the primary prevention of cancer and a healthy lifestyle, internet resources have been searched that may motivate and facilitate this study. Teachers interested in teaching this subject can download for free and use them with the method felt as most appropriate; they consist of text, graphs, tables, images, quizzes and an interactive atlas. According to a personal experience, the use of these educational resources helps teachers in teaching and students in learning about cancer prevention. According to the World Health Organisation, cancer is a leading and growing cause of mortality with 10 and 14 million new cases worldwide respectively in 2000 and 2012. Several risk factors have been identified; if they are avoided, more than 30% of the cancers can be prevented. The five most important modifiable risk factors, among many others, are: smoking, alcohol, overweight, physical inactivity, low consumption of vegetables and fruit. Cancer may also have genetic causes or be related to certain infections that are more common in some areas than in others. According to several documents also quoted in this article, numerous behaviours that reduce cancer risk may, at the same time, help to prevent other important diseases. Some of the documents quoted here show the very great difference in cancer incidence and mortality rates often existing between different geographic areas. For example, prostate cancer incidence per 100,000 persons per year is 104.4 in New Zealand, and 3.9 in Chennai, India. Many studies found an increase over time in the incidence of certain cancer types in people that move from countries where their risk is low to countries where their risk is high, thus suggesting the important role of environmental changes and lifestyle. As an example of this, the risk of breast cancer among Hispanic women migrating to US increases with the duration of residence in the immigration country, and becomes up to 4 - 6 times higher after 3 or more generations. This provides an example of what can happen in transitioning countries as a consequence of some lifestyle changes, unless measures are taken.
A Set of GRASS GIS-Based Shell Scripts for the Calculation and Graphical Display of the Main Morphometric Parameters of a River Channel  [PDF]
Aldo Clerici, Susanna Perego
International Journal of Geosciences (IJG) , 2016, DOI: 10.4236/ijg.2016.72011
Abstract: For the analysis of river evolution, the use of quantitative parameters can be quite useful in order to assess changes in the channel planform. Among the several parameters proposed by different authors in a number of papers, channel length and width, braiding and sinuosity indexes, and channel lateral shifting are proved to be the most effective ones for a quantitative analysis of river changes. However, the calculation of these parameters is time-consuming, tedious and error-prone, even where made in a GIS environment. This work describes four shell scripts that perform fast and automatic calculation of the morphometric parameters and draw curves showing thevariation of the calculated parameters along the entire channel development. The scripts arebased on commands of the GRASS GIS free and open source software and, as input, they require a simple vector map containing the essential features of a river channel,i.e.bankfull channel limits and longitudinal and lateral bars.
Energy Targeting for a Brewing Process Using Pinch Analysis  [PDF]
Noah Tibasiima, Aldo Okullo
Energy and Power Engineering (EPE) , 2017, DOI: 10.4236/epe.2017.91002
Abstract: The rising cost of energy and environmental concerns have led the brewing industry to search for techniques of reducing energy consumption in brewery operations. In this paper, pinch analysis was applied to a typical Ugandan based brewery process to target for the energy requirements of the process. Hint software was used for the analysis. At the chosen ΔTmin of 10, the minimum cooling and heating utility requirements of the brewery studied were determined as being 4862.21 kW and 8294.21 kW respectively, with a pinch temperature at 68. It was observed that using the technique, 1806.59 kW of energy could be recovered through process to process heat exchange which presented an energy saving potential of 21.5%. It is recommended that results from this study could be used in the design or retrofit of a heat exchanger network of a brewery for improved energy efficiency. Considerations can also be made for other values of ΔTmin.
Spectral and Finite Difference Solutions of the Hyperbolic Heat Transport Equation for Thermoelectric Thin Films  [PDF]
Aldo Figueroa, Federico Vázquez
Applied Mathematics (AM) , 2013, DOI: 10.4236/am.2013.410A3004

This paper presents the numerical comparison in the solution of the hyperbolic transport Equation that models the heat flux in thermoelectric materials at nanometric length scales when the wave propagation of heat dominates the diffusive transport described by Fourier’s law. The widely used standard finite difference method fails in well-reproducing some of the physics presented in such systems at that length scale level. As an alternative, the spectral methods assure a well representation of wave behavior of heat given their spectral convergence.
