River and stream ecosystems within cities can provide important Ecosystem Services (ES) to urban population along with the maintenance of biodiversity. Increasing urbanization with land use change can affect biodiversity, impacting ES provision, but the relationships between biota and ES are complex and poorly understood. This study aims to explore relationships between aquatic biodiversity (communities' composition and structure), urbanization and ES provided by urban streams. Nine streams were surveyed ...

Diatoms are a compulsory biological quality element in the ecological assessment of rivers according to the Water Framework Directive. The application of current official indices requires the identification of individuals to species or lower rank under a microscope based on the valve morphology. This is a highly time-consuming task, often susceptible of disagreements among analysts. In alternative, the use of DNA metabarcoding combined with High-Throughput Sequencing (HTS) has been proposed. The ...

Abstract Gastrointestinal Nematode Infection (GIN) are the main constraint to the production of small ruminants. Studies of medicinal plants have been an important alternative in the effort to control these parasites. Therefore, the purpose of this study was to evaluate the in vitro ovicidal and larvicidal activity of essential oil of Rosmarinus officinalis. The oil was extracted, analyzed by gas chromatography and tested on GIN eggs and larvae in six concentrations, 227.5mg/mL, 113.7mg/mL, 56.8mg/ ...

Benthic diatom communities are used in the ecological assessment of Portuguese rivers through the calculation of an autecological index, the IPS (Indice de Polluosensibilité Spécifique), officially adopted for Portugal. This index requires a high level of taxonomic expertise for morphological identification of individuals at species level. Advances in genomics, such as the DNA metabarcoding combined with high-throughput sequencing techniques offer a promising alternative to this classical approach, ...

Additive Manufacturing (AM) is a manufacturing process through which a 3D component is produced by consecutively adding material. One of the most promising AM processes is SLM. In SLM a laser completely melts metallic powder particles together forming a 3D component. SLM is known for its freedom of manufacturing constraints allowing complex geometries and high material efficiency. Topology Optimisation (TO) is an optimisation type that calculates the optimal material distribution for a given problem. ...

Despite the importance of citriculture in Brazil, very little is known about mite populations in citrus crops in the Northern Region. In the municipality of Manaus, 12 sprayed sweet orange orchards were surveyed every two weeks during seven months to record mite species amount, and to describe the abundance and distribution of the most important species. The size and age of the orchards varied from 3,360 to 88,080 m² and seven to 25 years, respectively. In the fourteen sampling period, leaves, twigs ...

The aromatic profiles of three white grape varieties (Alvarinho, Loureiro, and Avesso) and two red varieties (Amaral and Vinhão) from the Vinhos Verdes region have been established with respect to the monoterpenic compounds, present either in free and in glycosidically bound fractions. Seventeen compounds have been identified and quantified in the free form and 21 in the glycosidically bound form. Loureiro variety is characterized by important levels of linalool in the free fraction, above the odour ...

Abstract Gastrointestinal nematodes are responsible for great economic losses in sheep raising, and their control has long been carried out almost exclusively by the administration of anthelmintics, which have led to serious resistance problems. In the search for alternative control measures, phytotherapic research is highlighted. The aim of this study was to evaluate the action of Anethum graveolens (dill) essential oil on different stages of Haemonchus contortus life cycle, as well its cytotoxicity ...

vulnerability. The fact that these people share the environment with animals promotes the establishment of zoonotic parasitic infections, as well as the resultant parasitic cycles. Thus, parasites present in the environment must be identified, so that control measures can be recommended. In this context, this study’s objective was to evaluate environmental contamination by parasitic forms in a socially vulnerable community in southern Rio Grande do Sul. A total of 100 soil samples collected from ...

Antimicrobial resistance is a public health burden with worldwide impacts and was recently identified as one of the major causes of death in 2019. Fosfomycin is an antibiotic commonly used to treat urinary tract infections, and resistance to it in Enterobacteriaceae is mainly due to the metalloenzyme FosA3 encoded by the fosA3 gene. In this work, we adapted a CRISPR-Cas9 system named pRE-FOSA3 to restore the sensitivity of a fosA3+ Escherichia coli strain. The fosA3+ E. coli strain was generated ...

In this study, we tested the in vitro and in vivo larvicidal activity of Bacillus species against gastrointestinal nematodes in cattle, and their viability in the presence of anthelmintics. For in vitro tests, cattle feces naturally infected with trichostrongylides were incubated with spore suspensions of Bacillus circulans (Bcir), B. thuringiensis var. osvaldocruzi (Bto), B. thuringiensis var. israelensis (Bti) or B. thuringiensis var. kurstaki (Btk). Subsequently, residual larvae were counted and ...

Accurate prediction of flutter speeds is essential to efficient and safe flight testing for envelope expansion. Such accuracy is particularly difficult to obtain when analyzing flight data from speeds well below the critical speed at which flutter occurs. The flutterometer was introduced as a tool that could predict the onset of flutter even at lowspeed conditions; however, the conservatism in those predictions reduced testing efficiency. A method to augment the flutterometer to decrease the conservatism, ...

Is an exit from the euro possible? Is it desirable? We think that to deal with these questions, which may well not be the right ones just now, what is needed is a preliminary but thorough critique of the views on the European crisis that are most widespread. The heterodox approaches more and more underline a balance-of-payments problem, caused by cumulative differences in relative prices which have led to distinct growth strategies: export-led in the core, and debt-led in the periphery, focused ...

The Diagnosis and Recommendation Integrated System (DRIS) is an alternative tool for the evaluation of nutritional status and fertilizer recommendation of several crops. However, as this methodology implies the establishment of norms or standards, without which one cannot infer about the nutritional status of a crop, in Portugal this tool has little application. The aim of this study was to establish preliminary DRIS norms for vineyards in Portugal. From 2007 to 2009, petiole samples were collected ...

Due to anthelmintic resistance in nematodes, several research studies have been developed seeking control alternatives to these parasites. This study evaluated the in vitro action of Origanum vulgare on gastrointestinal nematode eggs of cattle. In order to evaluate the ability to inhibit egg hatch, different dried leaves extracts of this plant were tested, such as dye, hydroalcoholic and aqueous extracts at concentrations varying from 0.62 to 80 mg/mL. Each assay was accompanied by control containing ...

O controle dos helmintos gastrintestinais em ovinos, realizado exclusivamente através de anti-helmínticos, tem como consequência a seleção de populações de helmintos resistentes a praticamente todos os fármacos disponíveis. Isso tem motivado à busca de alternativas para controle, entre as quais destacamos a utilização de fitoterápicos. Neste contexto, o objetivo deste estudo foi avaliar a atividade ovicida in vitro do óleo essencial e do extrato hidroalcoólico de Ocimum basilicum em nematódeos de ...

This article reads the current Eurocrisis going far beyond the classical linear explanations of the dualism between an imperialist core and a victimised periphery. Instead, it mobilises the concepts of social capital and of global imperialist chain to demonstrate the continuum between the agendas of the dominant classes in both the core and the periphery and the use of intergovernmental regional organisations as privileged tools for their strategies of exposing national capitals to international ...
