Life Cycle Assessment of Industrial Building Construction and Recovery Potential. Case Studies in Seville

In Spain, most businesses are medium to small size enterprises, representing 90% of the total, but there is a lack of studies of the types of building this sector uses. The main objective of this paper is to present a method for the evaluation of small industrial construction projects to facilitate the introduction of eco-efficient solutions. For this, it is necessary to identify the most representative buildings and the aspects of these which have the most environmental impact. A methodology in place for the evaluation of dwelling construction is adapted, for the first time, to evaluate industrial buildings. The construction solutions characterized are those traditionally used in the sector, as identified through 87 surveys. A standardized classification of work units is proposed to enable the use of environmental product information, such as eco-labels and/or EPD, and LCA databases. The carbon footprint (CF) and water footprint (WF) are the indicators selected because of their straightforward message. Finally, a comparative analysis is performed showing the high recycling potential of concrete and cement which, along with metals and aggregates, control the impact in terms of CF. With respect to the WF indicator, plastic substitute aggregates are among the materials with the greatest impact.

River network rearrangements promote speciation in lowland Amazonian birds

Large Amazonian rivers impede dispersal for many species, but lowland river networks frequently rearrange, thereby altering the location and effectiveness of river-barriers through time. These rearrangements may promote biotic diversification by facilitating episodic allopatry and secondary contact among populations. We sequenced genome-wide markers to evaluate histories of divergence and introgression in six Amazonian avian species-complexes. We first tested the assumption that rivers are barriers for these taxa and found that even relatively small rivers facilitate divergence. We then tested whether species diverged with gene flow and recovered reticulate histories for all species, including one potential case of hybrid speciation. Our results support the hypothesis that river dynamics promote speciation and reveal that many rainforest taxa are micro-endemic, unrecognized and thus threatened with imminent extinction. We propose that Amazonian hyper-diversity originates in part from fine-scale barrier displacement processes, including river dynamics, which allow small populations to differentiate and disperse into secondary contact.

Geodiversity Assessment as a First Step in Designating Areas of Geotourism Potential. Case Study: Western Carpathians

Geodiversity is the natural diversity of features of geological structure, relief, and soil cover, including the relationships between these features, their properties, and their impact on other elements of the natural and cultural environment. It is described and analyzed using various types of quantitative, qualitative, or quantitative–qualitative methods. The concept of a geodiversity map presented in this article belongs to the third of these groups of methods. Despite the use of optimization methods in the form of a hexagon grid or the analytic hierarchy process calculator, it still remains partially subjective. The use of this method to calculate the geodiversity of an entire province (the Western Carpathians) gives a general view of the natural diversity of this area and allows regions to be selected for more detailed analyses or comparisons to be made between them. The geodiversity map is also a very good background on which to illustrate geotourist potential, which is expressed in terms of the number and distribution of geosites. However, in the case of the Western Carpathians, these two variables do not correlate with each other.

Governing a Pandemic: Assessing the Role of Collaboration on Latin American Responses to the COVID-19 Crisis

How do governments address complex, cross-sectoral problems, like the COVID-19 pandemic? Why were some Latin American countries more successful at containing the pandemic's most devastating health outcomes? We argue that national governments that were more collaborative in their response to COVID-19 were more successful in reducing death rates. Our original dataset offers a novel attempt to operationalise collaborative governance (CG). We undertake simple statistical tests to measure the relationship between CG and COVID-19-related mortality rates in Latin America. We then choose three case studies to assess whether collaboration was meaningful in practice. Initial evidence suggests governments that pursued CG were more effective at containing mortality rates early on in the pandemic. The collaboration helped to foster cooperation over resources; buy time to prepare for a potential case surge; and produce a unified message regarding what citizens should do to prevent viral spread.

Lupus-related protein-losing enteropathy associated with pseudo–pseudo Meigs’ syndrome and successfully treated with hydroxychloroquine

We herein report the first case of lupus-related protein-losing enteropathy associated with pseudo–pseudo Meigs’ syndrome. Lupus-related protein-losing enteropathy and pseudo–pseudo Meigs’ syndrome are extremely rare complications in patients with systemic lupus erythematosus, Both have a similar clinical course characterized by producing marked ascites, and respond to steroids in typical cases. However, in our case, steroid monotherapy was inadequate and the addition of hydroxychloroquine was effective for their treatment. Furthermore, no reports have previously confirmed elevated CA 125 levels with lupus-related protein-losing enteropathy or increased 99mTc-HSA activity with pseudo–pseudo Meigs’ syndrome. In addition, we are the first to report an evaluation of the histopathology of lupus-related protein-losing enteropathy. Previously reported cases have been described as being caused by either pseudo-Meigs’s syndrome or lupus-related protein-losing enteropathy as the cause of the rare pathology that causes marked pleural effusion and ascites in patients with systemic lupus erythematosus, but It has not been evaluated whether the other is co-occurring. Our case highlights that there is a potential case of overlapping lupus-related protein-losing enteropathy and pseudo-Pseudo-Meigs’s syndrome. Furthermore, it is possible that patients with marked ascites with elevated CA 125 levels were mistakenly diagnosed with Meigs’s syndrome or pseudo-Meigs’s syndrome associated with malignant or benign ovarian tumors and underwent surgery. Clinicians should not forget SLE with pseudo-Pseudo-Meigs’s syndrome as one of the differential diagnoses for marked ascites with elevated CA 125 levels.

Money creation and banks’ interest rate setting

Purpose This study aims to examine a potential case of interdependence in loan and deposit interest rate setting. Design/methodology/approach The authors set up a theoretical microsimulation model with endogenous loan interest rate determination via a learning algorithm. Findings The authors show that in certain environments, it may be beneficial for large banks to incorporate information on retail funding costs into the lending rate setting decision. Originality/value The author’s model is based on the realistic money creation mechanism.

Geostatistical analysis of spatial variability of the liquefaction potential – Case study of a site located in Algiers (Algeria)

The city of Algiers (Algeria) is a highly seismic area, and therefore, soil liquefaction poses a major concern for structures resting on sandy soil. A campaign of 62 static penetration tests or cone penetrometer tests (CPT) was carried out on a site located in the commune of Dar El Beïda in Algiers. The soil Liquefaction Potential Index (LPI) values were assessed, for each borehole, based on the simplified procedure of Seed and Idriss. On the other hand, the geographic information system and geostatistical analysis were used to quantify the risk of soil liquefaction at the studied site. It is worth mentioning that the (LPI) was taken as a regionalized variable. In addition, the experimental variogram was modeled on the basis of a spherical model. Also, the interpolation of the LPI values in the unsampled locations was performed by the Kriging technique using both isotropic and anisotropic models. Kriging standard deviation maps were produced for both cases. The cross-validation showed that the anisotropic model exhibited a better fit for the interpolation of the values of the soil liquefaction potential. The results obtained indicated that a significant part of the soil is liable to liquefy, in particular in the northwestern region of the study area. The findings suggest that there is a proportional relationship between the risk of liquefaction and the increase or decrease in seismic acceleration.
