Dilemmas of girls and women in engineering: a study in Portugal

The reason that girls and women withdraw from science and technology education and careers has been a universal concern in the social sciences. This study investigated how gendered constructions of identity are translated into the barriers and fears that female students and professional women experience in decision-making about their careers. We conducted interviews with 63 girls and 39 women in academic and professional engineering careers, focusing on their interpersonal relationships with boys and men in their school and occupational engineering settings, respectively. Participant discourse highlighted the difficulties women face when managing the antagonistic discourses of femininity and masculinity in a social environment in which they are frequently forced to submit to hegemonic masculinity. The consequences of women’s differing discourses about the “masculine world” and the “feminine world” are discussed, and some strategies for creating more equalitarian relational environments in school and work settings are discussed.Fundação para a Ciência e a Tecnologia (FCT

Koppen-Geiger and Thornthwaite climatic classification for the metropolitan region of the Cariri, Ceará

The aim of the present work was to compare the Koppen-Geiger and Thornthwaite methods for Climatic Classification of the Metropolitan Region of Cariri, state of Ceará, Brazil. The study area comprises the nine municipalities in the metropolitan region of the Cariri, being Juazeiro de Norte, Crato, Barbalha, Caririaçu, Farias Brito, Missão Velha, Nova Olinda, Jardim and Santana do Cariri. The temperature and rainfall data for the metropolitan region of the Cariri were submitted to Koppen-Geiger and Thornthwait classification, in order to compare the results. All weather data on precipitation and monthly temperature comes from the Data-Climate website, which provides world-class weather data for cities. There is a paucity of information about the climatic temperature and humidity normal in all cities, since not all have rain stations and data published by official institutions. This makes it difficult for public planning for the application of resources, the need for technical assistance and the implementation of technologies for water abstraction, as well as for research. The Köppen-Geiser climate classification is simpler to employ, however, the Thornthwaite classification has a more detailed result on the site. According to the Koppen-Geiser classification, the nine municipalities present in the metropolitan region of the Cariri are classified as Aw savanna climate. For Thornthwait, they can be classified generally as B1, B3 and C2, around humid to moist subhumid

Disinfection of cuttings and of soil with eucalyptus oil on Peruvian carrot yield

Foi estudado o efeito do óleo de eucalipto na desinfecção de mudas e do solo sobre a produção e no controle de doenças durante o ciclo de cultivo da mandioquinha-salsa ‘Amarela de Carandaí’. Os tratamentos originaram-se do fatorial 2 (sem-MS e com-MC desinfecção das mudas em solução aquosa com 1% do óleo, por 35”) x 3 (sem- SSPOE e com-SCPOE pulverização do solo, antes ou depois do plantio, com solução aquosa com 2% do óleo). Foram realizadas colheitas das plantas aos 224 e 266 dias após o plantio-DAP. As massas frescas de folhas, rebentos e coroas foram semelhantes estatisticamente dentre as MS mas, dentro das MC, os maiores valores corresponderam às plantadas em SCPOE. As maiores produções de raízes comerciais aos 224DAP (5,94 e 6,90 t ha-1) e aos 266DAP (7,07 e 7,47 t ha-1) foram dos tratamentos onde as MS e MC foram plantadas em SCPOE antes do plantio. Foram observados sintomas de queima das folhas (associação de Alternaria sp. e de Septoria sp.) e de podridões das coroas e dos rebentos (Sclerotium sp.). Concluiu-se que, para se obter maior produção de raízes comerciais da mandioquinha-salsa, usando mudas desinfetadas ou não, deve-se pulverizar óleo de eucalipto no solo antes do plantio, embora sem esperar efeito sobre doenças foliares e podridões de final de ciclo.The effect of eucalyptus oil as disinfectant of cuttings and of soil on yield and disease control during cultivation cycle of ‘Amarela de Carandaí’ Peruvian carrot, was studied. Treatments were originated from 2 (without-MS and with MC disinfection of cuttings in aqueous solution with 1% of oil, for 35”) x 3 (without-SSPOE and with-SCPOE sprinkling on the soil, before and after planting, with aqueous solution with 2% of oil) factorial scheme. Harvests were done on 224 and 266 days after planting-DAP. Fresh masses of leaves, shoots and crowns were similar statistically among MS but, among MC, the highest values corresponded to those planted in SCPOE. The highest yields of commercial roots on 224DAP (5.94 and 6.90 t ha-1) and 266DAP (7.07 and 7.47 t ha-1) were from treatments where MS and MC were planted in SCPOE before planting. Symptoms of burning leaves (association of Alternaria sp and of Septoria sp) and of rot of crows and shoots (Sclerotium sp) were observed. It was concluded that, in order to obtaining a greater yield of commercial roots of Peruvian carrot, using cuttings that were disinfected or not, eucalyptus oil must be sprinkled on soil before planting, although without waiting effects on foliar diseases and rots at the final of the cycle.Facultad de Ciencias Agrarias y Forestale

Metabolic profiling and antibacterial activity of Eryngium pristis Cham. & Schltdl. - prospecting for its use in the treatment of bacterial infections

Morbidity and mortality of the infected patients by multidrug-resistant bacteria have increased, emphasizing the urgency of fi ght for the discovery of new innovative antibiotics. In this sense, natural products emerge as valuable sources of bioactive compounds. Among the biodiversity, Eryngium pristis Cham. & Schltdl. (Apiaceae Lindl.) is traditionally used to treat thrush and ulcers of throat and mouth, as diuretic and emmenagogue, but scarcely known as an antimicrobial agent. With this context in mind, the goals of this study were to investigate the metabolic profi le and the antibacterial activity of ethanolic extract (EE-Ep) and hexane (HF-Ep), dichloromethane (DF-Ep), ethyl acetate (EAF-Ep) and butanol (BF-Ep) fractions from E. pristis leaves. Gas Chromatography-Mass Spectrometry (GC-MS) was performed to stablish the metabolic profi le and revealed the presence of 12 and 14 compounds in EAF-Ep and HF-Ep, respectively. β-selinene, spathulenol, globulol, 2-methoxy-4-vinylphenol, α-amyrin, β-amyrin, and lupeol derivative were some of phytochemicals identifi ed. The antibacterial activity was determined by Minimal Inhibitory Concentration (MIC) using the broth micro-dilution against eight ATCC® and fi ve methicillin-resistant Staphylococcus aureus (MRSA) clinical strains. HF-Ep was the most eff ective (MIC ≤ 5,000 μg/μL), being active against the largest part of tested Gram-positive and Gram-negative bacterial strains, including MRSA, with exception of Escherichia coli (ATCC 25922) and Pseudomonas aeruginosa (ATCC 9027) and (ATCC 27853). These results suggest that E. pristis is a natural source of bioactive compounds for the search of new antibiotics which can be an interesting therapeutic approach to recover patients mainly infected by MRSA strains.info:eu-repo/semantics/publishedVersio
