BACKGROUND: Cucurbit powdery mildew elicited by Podosphaera fusca (Fr.) U Braun & N Shishkoff limits crop production in Spain. Disease control is largely dependent on fungicides such as sterol demethylation inhibitors (DMIs). Fungicide resistance is an increasing problem in this pathogen. To overcome such risk, it is necessary to design rational control programmes based upon knowledge of field resistance. The aim of this study was to investigate the state of DMI sensitivity of Spanish P. fusca populations and provide tools for improved disease management. RESULTS: Using a leaf-disc assay, sensitivity to fenarimol, myclobutanil and triadimenol of 50 isolates of P. fusca was analysed to determine discriminatory concentrations between sensitive and resistant isolates. As no clearly different groups of isolates could be identified, discriminatory concentrations were established on the basis of maximum fungicide field application rate, 100 mg L-1 for the three fungicides tested. Subsequently, a survey of DMI resistance was carried out in different provinces located in the south central area of Spain during the cucurbit growing seasons in 2002, 2003 and 2004. Examination of a collection of 250 isolates revealed that 23% were resistant to fenarimol and 7% to triadimenol, the provinces of Almería, Badajoz and Murcia being the locations with the highest frequencies of resistance. By contrast, no resistance to myclobutanil was found. CONCLUSION: Results show that fenarimol and, to a lesser extent, triadimenol have become less efficient for controlling cucurbit powdery mildew in Spain. These are important observations that should lead to reconsideration of the current disease management programmes. © 2010 Society of Chemical Industry.

Aquaculture Environment Interactions | Year: 2016
Aquaculture is an increasingly important food-producing sector, providing protein for human consumption. However, marine aquaculture often struggles for space due to the crowded nature of human activities in many marine coastal areas, and because of limited attention from spatial planning managers. Here, we assess the need for coastal spatial planning, emphasising the establishment of suitable areas for the development of marine aquaculture, termed Allocated Zones for Aquaculture (AZAs), in which aquaculture has secured use and priority over other activities, and where potential adverse environmental impacts and negative interactions with other users are minimised or avoided. We review existing examples of marine aquaculture spatial development worldwide and discuss the proper use of site selection in relation to different legal and regulatory requirements. National or regional authorities in charge of coastal zone management should carry out spatial planning defining optimal sites for aquaculture to promote development of sustainable marine aquaculture and avoid conflict with other users, following a participatory approach and adhering to the principles of ecosystem-based management. © The authors 2015.

The objective of this study is to evaluate the impact of a subsidy policy for construction companies in Andalusia (Spain), which enables them to acquire new scaffolds. The rate of falls from scaffolds within the Andalusian construction sector in the period 2009–2011 was analysed. A randomised controlled trial was not possible as the subsidy was granted according to a public and competitive call. A quasi-experimental design based on an intervention group (subsidised companies) and a control group was chosen. Companies in the control group were selected from the social security census of companies in order to avoid selection bias. The subsidy policy has led to an overall 71% decrease in the rate of accident involving falls to a lower level in the companies that received grants in the period 2009–2011. The confidence interval for the comparison for the before–after difference in rates between the intervention group and the control group is found significant (confidence 95%, p = 0.05). The improvement of scaffolds was effective in reducing rates of accident with falls to a lower level. This intervention should be a priority in public policies. The process of standardisation of equipment with high accident risk should be developed further. © 2013, © 2013 Taylor & Francis.

Oyster remains in Roman archaeological layers in Circle of the Strait sites is a constant, from the beginning of the Roman conquest up to the Late Antiquity. Oyster-farming evidences are reported in Iulia Traducía (modern Algeciras) in V c. A.D. contexts. The shell remains importance in the context of the fishing and fish-processing activities is an element known in Baelo Claudia's roman city by diverse sources. In this work we present beforehand the first information of an archaeological dig carried out in the year 2009 in the oriental wall of this hispano-roman city, in which there have been exhumed several structures of imperial times. Among them, a context dating back to the mid of the I c. A.D. was brought to light. It contained dozens of oysters and other shell remains attesting the alimentary importance of such marine products in the city. We discuss the archaeological context of the finding, interpreted as food waste of a convivium or banquet, as well as a series of historical inferences related to the consumption and gastronomic importance of oysters in this important Roman city of the Strait of Gibraltar, focused on the exploitation of marine resources.

Aims and objectives: To evaluate at what age parous and nonparous women were diagnosed with breast cancer. Factors taken into account for parous women were whether they had breastfed their children, and if so, the length of the lactation period. Other factors considered for both groups were obesity, family histories of cancer, smoking habits and alcohol consumption. Background: Breast cancer is the most common form of cancer in younger women in Western countries. Its growing incidence as well as the increasingly early age of diagnosis led us to carefully analyse its possible causes and the preventive measures to be taken. This is a particularly important goal in epidemiological research. Design: A retrospective study of the clinical histories of patients diagnosed with breast cancer at the San Cecilio University Hospital in Granada (Spain). Methods: In this study, we analysed 504 medical records of female patients, 19-91 years of age, who had been diagnosed and treated for breast cancer from 2004-2009 at the San Cecilio University Hospital in Granada (Spain). Relevant data (age of diagnosis, period of lactation, family history of cancer, obesity, alcohol consumption and smoking habits) were collected from the clinical histories of each patient and analysed. A conditional inference tree was used to relate the age of diagnosis to smoking habits and the length of the lactation period. Results: The conditional inference tree identified significant differences between the age of the patients at breast cancer diagnosis, smoking habits (p < 0·001) and lactation period if the subjects had breastfed their children for more than six months (p = 0·006), regardless of whether they had a family history of cancer. Conclusions: Our study concluded that breastfeeding for over six months not only provides children with numerous health benefits, but also protects mothers from breast cancer when the mothers are nonsmokers. Relevance to clinical practice: Nurses play a crucial role in encouraging new mothers to breastfeed their children, and this helps to prevent breast cancer. © 2013 John Wiley & Sons Ltd.
