Crop diversification practices (CDPs) are alternative strategies aimed to achieve sustainable cropping systems and food production overcoming the agro-environmental impacts of conventional cropping systems such as monoculture. Thus, this paper aims to improve the knowledge of implementing CDPs in different European pedoclimatic regions by assessing the economic performance at the farm level. CDPs are compared with conventional cropping systems and clustered in terms of their gross margin (GM) results and variations. Farm-level assessment shows that CDPs provide positive economic results, representing an adaptive management strategy for ecological transition, without compromising economic sustainability. Particularly, the main findings show that (1) the impact of diversification depends more on crop type than on the selected CDPs, (2) most farms exhibited a low GM with low economic impact, and (3) there is a great likelihood that the CDPs facilitate the buildup of more resilient farming systems.

In recent decades, large amounts of construction and demolition waste (CDW) have been generated and accumulated throughout Europe, which is a challenge to manage and control nowadays. This work shows the results of a study carried out with samples of ceramic recycled aggregates (CRAs) and recycled concrete aggregates (RCAs) mixed with cement (C) in mortars. The main objective of this research is to demonstrate how, by adding CRAs and RCAs to a mixture of cement and natural aggregate (NA), it is possible to develop a high-strength mortar and achieve the best mixing ratio. To achieve these objectives, the characterization of the samples was initially carried out such as XRF, XRD and SEM. Next, tests were carried out on the products obtained, such as the consistency of the fresh mortar and the density of the specimens. Finally, a study of mechanical compressive strength was performed at 7, 28 and 200 days. The results show that although both CRAs and RCAs negatively affect the curing process of the specimens, it is possible to develop mortars with compressive strengths greater than 20 MPa. An obvious increase in mechanical compressive strengths was seen between 7 and 200 days of analysis. The results achieved in this research could be an important guide for the management of CDWs by local industries, thus favouring the development of the circular economy. [ABSTRACT FROM AUTHOR]

TRAINING of scientists ,DEVELOPING countries ,ONLINE education ,SCIENTIFIC communication ,EDUCATIONAL exchanges ,VIRTUAL communities - Abstract
Introduction: Limited financial resources available for science research and training in Latin America preclude most young scientists from having international experiences. This limitation has an impact on their development as scientists because it restricts the opportunities to interact with cutting-edge researchers and receive mentoring from such professionals. The lack of international forums in which to present their work may limit the expansion of their soft skills in areas such as oral communication, especially regarding giving scientific presentations in the English language. The popularity of online technologies, even in developing countries, allows for new methods in which students can have international experiences without extensive costs. Methods: The International Academic Virtual Exchange network (IAVE) was created as a way to provide students in the developing world access and collaborations with international partners. The student members of this network include graduate students in Medical Physics as well as Physics undergraduates. The network currently has members from 10 different countries in the Americas and Europe. Activities such as weekly journal clubs, scientific conferences, workshops and a peer-reviewed annual congress are organized online using free software that allow for real-time audience interaction via chat or video. Most activities are conducted in English, with occasional activities in Spanish, to allow participation of students at all levels of English command. The annual IAVE Congress accepts abstracts in two modalities, original research and literature review. This allows students with limited access to research opportunities, the chance to hone their literature research, and presentation skills using their available resources. Both modalities undergo the same peer-review process and students present through videoconference to an international audience. Results and discussion: Since 2017, IAVE has hosted over 60 webinars, including weekly sessions, covering subjects from clinical applications of radiation to professional development topics, such as scientific communication. These webinars include presentations of both graduate and undergraduate students in Latin America and the United States. Webinars with professional speakers are organized at each site institution and broadcast to the IAVE network, giving its members the chance to interact with those experts. Two IAVE Congresses have been organized thus far, with participation of 11 students in 2018 and another 11 in 2019, for a total of 18 different students from Latin America (graduate and undergraduate level) and 4 students from the United States (graduate level). The Congresses had online audiences in the Americas and Europe. Mentoring activities and research opportunities are organized at each site institution and across-sites. Conclusions: It is possible to establish a beneficial, fruitful, international relationship between initially unaffiliated institutions with limited resources, through the efforts and commitment of participating members. IAVE has been able to plan and execute several types of activities that increase the opportunities of interaction between members regardless of geographical limitations, providing students the opportunity to participate in international scientific activities, even without physical access to research or travel funding.

Cocaine is still one of the most commonly used illicit substances worldwide, with an estimated 4 million users in Europe in the last year. Hair samples have been widely used for the determination of episodic or repeated consumption of this substance, but the use of miniaturized techniques for hair sample clean-up has been challenging due to the sample complexity. Despite hair's complex matrix, MEPS provides a method that is fast, reduces the volume of extraction solvents used, and offers low-cost options (since extraction beds may be reused several times). Microextraction by packed sorbent using a mixed-mode sorbent was optimized for hair sample clean-up in order to determine cocaine, benzoylecgonine, ecgonine methyl ester, norcocaine, cocaethylene and anhydroecgonine methyl ester by gas chromatography coupled to tandem mass spectrometry. The method was fully validated according to internationally accepted criteria, presenting good linearity between the limits of quantification (0.01–0.15) and 5 ng/mg. Precision and accuracy resulted in coefficients of variation typically lower than 15%, with mean relative errors within ±15% for all compounds, except for the limit of quantification (±20%). The present work describes the first application of microextraction by packed sorbent for the concentration of cocaine and metabolites extracted from hair samples. [ABSTRACT FROM AUTHOR]

Objective: This report outlines a multispecialty implementation effort which included 12 specialty practices and 28 clinicians within Regional Health Command Europe (RHCE) and Landstuhl Regional Medical Center (LRMC) to pilot an in-home virtual health (VH) program using existing resources. Methods and Materials: Synchronous VH encounters were performed using an Acano desktop conferencing client (Cisco Systems, Inc, San Jose, CA) and a USB web camera at the provider (distant) site and the patient’s own computer or device in the home. A web real-time conferencing (Web RTC) server provided the connections. Results: Between October 2016 and May 2018, 310 synchronous VH appointments to patients’ homes in 23 geographic locations in 9 countries on 3 different continents were completed; 28 skill type I and II specialty providers at LRMC, SHAPE Belgium Army Health Clinic (AHC), and Vilseck AHC, Germany Primary Care Clinic participated. The providers represented 9 distinct specialties and primary care. Appointment types were as follows: 85 (39%) follow-up type appointments; 70 (32%) group type appointments; 65 (30%) initial specialty care appointments. The 3 most active clinics were Pediatric Gastroenterology with 88 (28%), the Nutrition Clinic with 82 (26%), and the Traumatic Brain Injury Clinic with 63 (20%) encounters. Full audio and video connectivity rate was 97%, excluding reconnects after dropped calls which occasionally occurred. Patient satisfaction scores were high 16/17 (94%) with 5% of patients surveyed. Conclusion: Low complexity synchronous VH appointments were successfully accomplished across a broad spectrum of health care services and appointment types. Landstuhl RMC specialists received consults from sites across a vast geographic area including Europe, the Middle East, and Africa. An in-home VH option gives providers a special tool to extend services far beyond traditional boundaries. This pilot project helped RHCE and LRMC providers gain valuable experience extending care to the home and will provide foundational knowledge for future VH efforts targeting groups and outcomes.

DIAGNOSIS of HIV infections , *METROPOLITAN areas , *MEDICAL care costs , *PUBLIC health , *MEN who have sex with men , *AIDS serodiagnosis - Abstract
The non-decreasing incidence of HIV among men who have sex with men (MSM) has motivated the emergence of Community Based Voluntary Counselling and Testing (CBVCT) services specifically addressed to MSM. The CBVCT services are characterized by facilitated access and linkage to care, a staff largely constituted by voluntary peers, and private not-for-profit structures outside the formal health system institutions. Encouraging results have been measured about their effectiveness, but these favourable results may have been obtained at high costs, questioning the opportunity to expand the experience. We performed an economic evaluation of HIV testing for MSM at CBVCT services, and compared them across six European cities. We collected retrospective data for six CBVCT services from six cities (Copenhagen, Paris, Lyon, Athens, Lisbon, and Ljubljana), for the year 2014, on the number of HIV tests and HIV reactive tests, and on all expenditures to perform the testing activities. The total costs of CBVCTs varied from 54,390€ per year (Ljubljana) to 245,803€ per year (Athens). The cost per HIV test varied from to 41€ (Athens) to 113€ (Ljubljana). The cost per HIV reactive test varied from 1966€ (Athens) to 9065€ (Ljubljana). Our results show that the benefits of CBVCT services are obtained at an acceptable cost, in comparison with the literature (values, mostly from the USA, range from 1600$ to 16,985$ per HIV reactive test in clinical and non-clinical settings). This result was transversal to several European cities, highlighting that there is a common CBVCT model, the cost of which is comparable regardless of the epidemiological context and prices. The CBVCT services represent an effective and “worth it” experience, to be continued and expanded in future public health strategies towards HIV. [ABSTRACT FROM AUTHOR]

Abstract: Senegalese sole, Solea senegalensis, is a flat fish of growing interest in European aquaculture. In its culture viral infections are constant threats, thus understanding antiviral defences is a key factor for a successful industry. Mx proteins are IFN-induced proteins widespread in eukaryotes; however, their antiviral activity is unclear and the results variable among species. Therefore assessment of the putative Mx antiviral activity in each species is of interest. Our group has recently cloned the Senegalese sole Mx (SsMx) cDNA and in this study its antiviral activity was assessed by infecting CHSE-214 cells expressing recombinant SsMx, with sole aquabirnavirus. The antiviral activity against this pathogen was demonstrated by reduction in induced cytopathic effects, reduction in virus yield and decrease in viral transcripts. These findings contribute to our understanding of fish antiviral mechanisms and open the possibility of using this protein as a tool for fighting viral infections in aquaculture.

Vermicomposting is the process of organic waste degradation through interactions between earthworms and microbes. A variety of organic wastes can be vermicomposted, producing a nutrient-rich final product that can be used as a soil biofertilizer. Giving the prolific invasive nature of the Australian silver wattle Acacia dealbata Link in Europe, it is important to find alternatives for its sustainable use. However, optimization of vermicomposting needs further comprehension of the fundamental microbial processes. Here, we characterized bacterial succession during the vermicomposting of silver wattle during 56 days using the earthworm species Eisenia andrei. We observed significant differences in α- and β-diversity between fresh silver wattle (day 0) and days 14 and 28, while the bacterial community seemed more stable between days 28 and 56. Accordingly, during the first 28 days, a higher number of taxa experienced significant changes in relative abundance. A microbiome core composed of 10 amplicon sequence variants was identified during the vermicomposting of silver wattle (days 14 to 56). Finally, predicted functional profiles of genes involved in cellulose metabolism, nitrification, and salicylic acid also changed significantly during vermicomposting. This study, hence, provides detailed insights of the bacterial succession occurring during vermicomposting of the silver wattle and the characteristics of its final product as a sustainable plant biofertilizer.

Nervous necrosis virus (NNV), genus Betanodavirus, the etiological agent of the viral encephalopathy and retinopathy (VER), presents a genome with two positive-sense single-stranded RNA segments. Striped jack nervous necrosis virus (SJNNV) and red-spotted grouper nervous necrosis virus (RGNNV), together with reassortants RGNNV/SJNNV, are the betanodaviruses predominantly isolated in Southern Europe. An RGNNV/SJNNV reassortant isolated from Senegalese sole (wt160) causes high mortalities in this fish species. This virus presents differences in the sequence of the 3' non-coding region (NCR) of both segments compared to RGNNV and SJNNV reference strains. Previously, it has been reported that the reversion of two of these differences (nucleotides 1408 and 1412) in the RNA2 3'NCR to the SJNNV-type (recombinant r1408-1412) resulted in a decrease in sole mortality. In the present study, we have applied an OpenArray
® to analyse the involvement of sole immune response in the virulence of several recombinants: the r1408-1412 and two recombinants, developed in the present study, harbouring mutations at positions 3073 and 3093 of RNA1 3'NCR to revert them to RGNNV-type. According to the correlation values and to the number of expressed genes, the infection with the RNA2-mutant provoked the most different immune response compared to the immune response triggered after the infection with the rest of the viruses, and the exclusive and high upregulation of genes related to the complement system. The infection with the RNA1-mutants also provoked a decrease in mortality and their replication was delayed at least 24 h compared to the wt160 replication, which could provoke the lag observed in the immune response. Furthermore, the infection with the RNA1-mutants provoked the exclusive expression of pkr and the downregulation of il17rc. [ABSTRACT FROM AUTHOR]- Published

This article presents an analysis of Nights of Adrenaline by the Peruvian poet Carmen Ollé based on the notion of performatic body and affect. The poetic subject questions the imposed roles to women by androcentric society and manifests the migratory shift from the periphery (Lima) to Europe (the center). Likewise, Ollé proposes body liberation based on Anti-Psychiatry and Radical Psychiatry theorists as an implicit criticism to Psychiatry, Psychoanalysis and religion. For this reason, she postulates the emergence of a queer desire. [ABSTRACT FROM AUTHOR]

Non-perennial rivers and streams (NPRS) cover > 50% of the global river network. They are particularly predominant in Mediterranean Europe as a result of dry climate conditions, climate change and land use development. Historically, both scientists and policy makers underestimated the importance of NRPS for nature and humans alike, mainly because they have been considered as systems of low ecological and economic value. During the past decades, diminishing water resources have increased the spatial and temporal extent of artificial NPRS as well as their exposure to multiple stressors, which threatening their ecological integrity, biodiversity and ecosystem services. In this paper, we provide a comprehensive overview of the structural and functional characteristics of NPRS in the European Mediterranean, and discuss gaps and problems in their management, concerning their typology, ecological assessment, legislative and policy protection, and incorporation in River Basin Management Plans. Because NPRS comprise highly unstable ecosystems, with strong and often unpredictable temporal and spatial variability – at least as far as it is possible to assess – we outline the future research needs required to better understand, manage and conserve them as highly valuable and sensitive ecosystems. Efficient collaborative activities among multidisciplinary research groups aiming to create innovative knowledge, water managers and policy makers are urgently needed in order to establish an appropriate methodological and legislative background. The incorporation of NPRS in EU-Med River Basin Management Plans in combination with the application of ecological flows is a first step towards enhancing NPRS management and conservation in order to effectively safeguard these highly valuable albeit threatened ecosystems.
