Periods of drought and low streamflow can have profound impacts on both human and natural systems. People depend on a reliable source of water for numerous reasons including potable water supply and to produce economic value through agriculture or energy production. Aquatic ecosystems depend on water in addition to the economic benefits they provide to society through ecosystem services. Given that periods of low streamflow may become more extreme and frequent in the future, it is important to study the factors that control water availability during these times. In the absence of precipitation the slower hydrological response of groundwater systems will play an amplified role in water supply. Understanding the variability of the fraction of streamflow contribution from baseflow or groundwater during periods of drought provides insight into what future water availability may look like and how it can best be managed. The Mills River Basin in North Carolina is chosen as a case-study to test this understanding. First, obtaining a physically meaningful estimation of baseflow from USGS streamflow data via computerized hydrograph analysis techniques is carried out. Then applying a method of time series analysis including wavelet analysis can highlight signals of non-stationarity and evaluate the changes in variance required to better understand the natural variability of baseflow and low flows. In addition to natural variability, human influence must be taken into account in order to accurately assess how the combined system reacts to periods of low flow. Defining a combined demand that consists of both natural and human demand allows us to be more rigorous in assessing the level of sustainable use of a shared resource, in this case water. The analysis of baseflow variability can differ based on regional location and local hydrogeology, but it was found that baseflow varies from multiyear scales such as those associated with ENSO (3.5, 7 years) up to multi decadal time scales, but with most of the contributing variance coming from decadal or multiyear scales. It was also found that the behavior of baseflow and subsequently water availability depends a great deal on overall precipitation, the tracks of hurricanes or tropical storms and associated climate indices, as well as physiography and hydrogeology. Evaluating and utilizing the Duke Combined Hydrology Model (DCHM), reasonably accurate estimates of streamflow during periods of low flow were obtained in part due to the model’s ability to capture subsurface processes. Being able to accurately simulate streamflow levels and subsurface interactions during periods of drought can be very valuable to water suppliers, decision makers, and ultimately impact citizens. Knowledge of future droughts and periods of low flow in addition to tracking customer demand will allow for better management practices on the part of water suppliers such as knowing when they should withdraw more water during a surplus so that the level of stress on the system is minimized when there is not ample water supply.

On 14th May, as part of National Mills Weekend, an open workshop was held outside the 18th century House Mill in Bromley by Bow, the world's largest tidal mill. Members of the Geezers Club in Bow worked in the open air with an engineer to construct the stream wheel, which is being developed in ‘flat pack’ format to maximize transferability. The wheel will be installed in the River Lea later this year.

The aim of this short essay is to analyze the techniques of argumentation developed by the writer and journalist Juan José Millás in his articles named Pie de Foto. Millás is known for his peculiar way of writing, in which language is highly unstable and is thereby apt to the creation of new perspectives and points of view. In the Pie de Foto, this ambivalence of language is enriched by the presence of a picture, of which his textual article is a comment. Using the definition given by Genette, Millás rhetoric is not a ‘restricted’ one but it is a complex system, in which also the apparently superficial figures can provide semantic effects and enrich information. Within this frame, irony plays a fundamental role because it helps questioning the standard discourse of politics. By means of techniques such as the mechanical reproduction and the ridiculing of the fallacies hidden in common sense, Millas raises ethical problems and develops a critique to the postmodern way of life in western countries.

This short essay deals with literary representations of identity and of social reality, especially in relation to the novelistic works published by the Spanish writer Juan José Millás. The article is divided into three parts. The first section is dedicated to a general overview of the new perspectives brought by the contemporary ‘linguistic turn’ in culture, which is currently considered as the product of different discourses and not as an ontological datum. The postmodern condition, on the other hand, is described as the age in which it has become radically difficult to rely on such ideas as “nation” and “people” for the construction of personal identity. The second part of the article identifies Millás’ poetics as an excellent example of describing the neurotic symptoms produced by the urban way of life in Western communities. Millás recognizes the separateness between language and material reality as the origin of the subject's isolation, especially in contemporary life. Finally, the third part handles with Lo que sé de los hombrecillos, the last novel by Millás, in which we witness a significant switch from neurosis to psychosis in the mind of the protagonist who offers us a distorted realisation of his idea of community and plenitude.

The milling of thin parts is a high added value operation where the machinist has to face the chatter problem. The study of the stability of these operations is a complex task due to the changing modal parameters as the part loses mass during the machining and the complex shape of the tools that are used. The present work proposes a methodology for chatter avoidance in the milling of flexible thin floors with a bull-nose end mill. First, a stability model for the milling of compliant systems in the tool axis direction with bull-nose end mills is presented. The contribution is the averaging method used to be able to use a linear model to predict the stability of the operation. Then, the procedure for the calculation of stability diagrams for the milling of thin floors is presented. The method is based on the estimation of the modal parameters of the part and the corresponding stability lobes during the machining. As in thin floor milling the depth of cut is already defined by the floor thickness previous to milling, the use of stability diagrams that relate the tool position along the tool-path with the spindle speed is proposed. Hence, the sequence of spindle speeds that the tool must have during the milling can be selected. Finally, this methodology has been validated by means of experimental tests.

%'e compute the divergent part of the three-point vertex function of the non-Abelian Yang-Mills gauge field theory within the stochastic quantization approach to the one-loop order. This calculation allows us to find four renormalization constants which, together with the four previously obtained, verify, to the calculated order, some Ward identities.

TESLA project (Transfering Energy Save Laid on Agroindustry) financed by the European Commission, had the main goals of evaluating the energy consumption and to identify the best available practices to improve energy efficiency in key agro-food sectors, such as the olive oil mills. A general analysis of energy consumptions allowed identifying the partition between electrical and thermal energy (approximately 50%) and the production processes responsible for the higher energy consumptions, as being the in the mill and paste preparation and the phases separation. Some measures for reducing energy waste and for improving energy efficiency were identified and the impact was evaluated by using the TESLA tool developed by Circe and available at the TESLA website.
