Control of the pinewood nematode Bursaphelenchus xylophilus by essential oils and extracts obtained from plants: a review.

The pinewood nematode (PWN), Bursaphelenchus xylophilus, is a serious threat to forest ecosystems at a global scale. The nematode has become a major quarantine problem due to its capability to completely destroy Pinus spp. trees, with great damage to the wood industry. Controlling the nematode inside a living tree is quite difficult, the techniques used being often ineffective and quite expensive. In the coming years, most chemicals used to control nematodes will be banned and replaced by safer and environmentally friendly products. As so, chemicals naturally produced by plants will play an important role in controlling diseases such as pine wilt. Plants, particularly aromatic ones, are commonly used due to the chemical properties of their secondary metabolites. Among these, essential oils and/or extracts are highly employed and are being tested as possible control of some organisms, like nematodes. Recent publications have evaluated essential oils derived from different plant species as natural nematicides [1; 2], antibacterial [3], anti-fungal [4] as well as insecticidal [5]. Concerning control of the PWN, a significant amount of information on plants tested, results obtained and employed techniques, is available. Our revision has extensively gathered this information, making it easier to search, read and use. It may become useful information for future studies on the subject, since it will be possible to check the plants already tested. Although numbers aren´t definitive, so far, tested plants are distributed amongst 148 families. The extracts or essential oils of plants belonging to the Asteraceae, Lamiaceae and Euphorbiaceae families show promising results on controlling the pinewood nematode

Na actualidade, a crescente preocupação com a protecção ambiental, que se verifica em todas as áreas, leva a que, a nível da Engenharia Rodoviária, sejam já utilizadas diversas técnicas de reciclagem de subprodutos resultantes de trabalhos de beneficiação e reforço de pavimentos flexíveis. Neste artigo enquadra-se o processo de reutilização de materiais recorrendo à mistura de material fresado com pó e cimento, dentro dos processos de reciclagem de pavimentos e apresentam-se resultados que permitem concluir que a técnica pode constituir uma alternativa à reutilização de subprodutos da construção, em substituição de camadas granulares de pavimento

Anesthesia and Rheumatoid Arthritis

SummaryBackground and objectivesRheumatoid arthritis (RA) is a chronic inflammatory disease of unknown etiology. It is known that RA patients have a reduced life expectancy when compared with the general population. Rheumatic diseases are numerous and occur with high variability; some of them develop very rapidly while others occur chronically provoking disability throughout life. Anesthetic risks in osteoarticular disorders involve not only the mechanical deformations caused by the disease, but also the cardiovascular, respiratory, renal, and digestive systems.ContentsThe purpose of this review was to stress the importance of stages in disease process that may affect anesthesia control before, during, and after surgery, highlighting the authors’ experience in a retrospective review of patients with juvenile rheumatoid arthritis (JRA) undergoing placement of orthopedic prosthesis with emphasis on intubation techniques.ConclusionsRheumatoid arthritis patients can present a number of complex problems for the anesthesiologist. This requires careful preoperative evaluation; anesthesia requires experience with the technique; and postoperative care should be judiciously chosen to meet the specific needs of the patient. The procedure requires effective communication among surgeon, rheumatologist and anesthesiologist so each member of the multidisciplinary team can contribute with his/her expertise in order to better benefit the patient

Contribution for the reuse of rap material in pavements structural layers

O objectivo principal deste artigo é promover a utilização de material fresado em camadas estruturais de pavimento, reutilizando materiais provenientes da reconstrução de camadas de pavimentos flexíveis. Os resultados laboratoriais realizados sobre misturas de material fresado, pó de pedra e cimento (FPC) permitem concluir que uma camada de sub-base de pavimento flexível realizada com esta mistura, pode resultar numa camada de elevada resistência. A técnica é económica e ambientalmente justificada, dado que constitui uma solução para a reutilização de um subproduto da construção, reduzindo a necessidade de utilizar novos agregados. Por outro lado, o aumento da capacidade resistente da camada de sub-base realizada com FPC, pode traduzir-se na possibilidade de diminuir a espessura das restantes camadas de pavimento, reduzindo o consumo de novos agregados e ligantes betuminosos.The main purpose of this article is to promote the use of RAP (Reclaimed Asphalt Pavement) in pavement structural layers, reusing material produced by the reconstruction of flexible pavements layers. Laboratorial results made on mixtures of RAP material, stone powder and cement (FPC) allow concluding that a pavement sub-base layer made with this mixture can constitute a layer with an improved resistance. The technique is economic and environmentally justified, thus it represents a solution for the reuse of a construction by-product, reducing the use of new aggregates. By the other hand, the increase of resistance of the sub-base layer made with FPC, can allow reducing the thickness of other layers, reducing the consumption of new aggregates and bituminous binders

Sound production in the Meagre, Argyrosomus regius (Asso, 1801): intraspecific variability associated with size, sex and context

Many fish taxa produce sound in voluntary and in disturbance contexts but information on the full acoustic repertoire is lacking for most species. Yet, this knowledge is critical to enable monitoring fish populations in nature through acoustic monitoring.Portuguese Foundation for Science and Technology: PTDC/BIA-BMA/30517/2017; SFRH/BD/115562/2016; UID/MAR/04292/2019; UID/BIA/00329/2019; PTDC/BIA-BMA/29662/2017.info:eu-repo/semantics/publishedVersio

Patient satisfaction with healthcare services and the techniques used for its assessment: a systematic literature review and a bibliometric analysis

Patient satisfaction with healthcare provision services and the factors influencing it are be-coming the main focus of many scientific studies. Assuring the quality of the provided services is essential for the fulfillment of patients' expectations and needs. Thus, this systematic review seeks to find the determinants of patient satisfaction in a global setting. We perform an analysis to evaluate the collected literature and to fulfill the literature gap of bibliometric analysis within this theme. This review follows the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) approach. We conducted our database search in Scopus, Web of Science, and PubMed in June 2022. Studies from 2000-2021 that followed the inclusion and exclusion criteria and that were written in English were included in the sample. We ended up with 157 articles to review. A co-citation and bibliographic coupling analysis were employed to find the most relevant sources, authors, and documents. We divided the factors influencing patient satisfaction into criteria and explanatory variables. Medical care, communication with the patient, and patient's age are among the most critical factors for researchers. The bibliometric analysis revealed the countries, institutions, documents, authors, and sources most productive and significant in patient satisfaction.info:eu-repo/semantics/publishedVersio
