An Evaluation of the Use of Calcium, Potassium and Silicon for the Management of Diaphorina citri Populations in Tahiti Lime Trees
Authors: RAMÍREZ-GODOY Augusto , PUENTES-PÉREZ Ginna , RESTREPO-DÍAZ Hermann
Published: April 2018

The recent appearance of the disease known as huanglongbing (HLB) in Colombia has caused the demand for alternative control methods for Diaphorina citri (i.e., the disease vector). Specifically, the use of nutrients, such as calcium (Ca), potassium (K) and silicon (Si), may provide some degree of plant defense against herbivory. One set of experiments (in the form of two separate experiments) was conducted on two different farms in the municipality of Jerusalén to study the effects of foliar and soil applications of nutrients (Ca, K and Si) on controlling the population dynamics of Diaphorina citri. Tahiti lime trees were treated as follows: i) untreated trees (absolute control); ii) clothianidin at a dose of 50 g active ingredient per hectare (chemical control); iii) Ca, K and Si foliar applications (at doses of 3 mL, 3 g and 2 mL of the commercial compound used per liter of H2O, respectively); and iv) soil application of potassium nitrate and potassium silicate (1 kg of commercial fertilizer per tree). Foliar sprays were carried out at 0 and 4 weeks after treatment (WAT) began; meanwhile, soil fertilization occurred at the beginning of the trial (i.e., 0 WAT). The results showed that differences were observed only in adults at 7 WAT, and the foliar calcium and silicon applications resulted in the lowest number of individuals (i.e., 1.13 per flush) compared with untreated trees (i.e., 3.13 per flush). The foliar clothianidin, Ca, Si and K sprays also affected the total number of nymphs. Additionally, Tahiti lime trees treated with either silicon or insecticide had fewer eggs than did trees in the other treatments. The use of these mineral nutrients showed a similar efficacy when compared to clothianidin, indicating that these mineral nutrients can enhance plant resistance. These observations suggest that foliar applications of K, Ca and Si could be considered as complementary tools within an integrated management program for D. citri in Colombia.

Hippophae salicifolia is an Euro-Asian species used in many industries, from medicine to cosmetics, nutrition, or soil sciences (enriching degraded fields, diminishing soil erosion, preventing and treating diseases). The purpose of this study was to analyse the culture of this species in Europe together with the chemical content of its fruits. In order to achieve this, Hippophae salicifolia seeds were sown in greenhouses, seedlings were planted in fields, while the fruits were harvested and analysed both fresh, as well as after preservation for 1 year and 5 months. The properties of H. salicifolia fruits were also compared with the fruits of Hippophae rhamnoides, both fresh and preserved for 7 months. The analysis have shown that fresh fruits contain an average quantity of 31; 811 and 231 mg/100 total carotenoid, polyphenol, and ascorbic acid, respectively. The vitamin C content was much higher than that observed for H. rhamonides. If kept in adequate conditions, H. salicifolia fruits lose only a small amount of vitamin C and exhibit a vitamin C content (224 mg/100g) superior to the fresh fruit of H. rhamonides (100-150 mg/100 g). By comparing the chemical characteristics of H. salicifolia and H. rhamnoides fruits preserved over a long period of time, a higher concentration of vitamin C was observed in H. salicifolia, while the differences between the other chemical characteristics were insignificant. The obtained results strongly suggest that H. salicifolia can be successfully cultured in Europe, while its exceptional fruit qualities can be capitalised on by a variety of industries.

Published: April 2018

In the present study, field experiments were conducted to determine the efficacy and compatibility of herbicides and fungicides in durum wheat under Mediterranean semi-arid conditions, in Central Greece. Our results indicate that the herbicide florasulam+2.4-D was safe and did not cause any injury when applied alone or with fungicides, while bromoxynil+2.4-D mixed with azoxystrobin or trifloxystrobin+prothioconazole caused injury symptoms on leaves. The injury symptoms were transient, and observed only at Velestino area, where low temperatures and broad diurnal temperature fluctuations were recorded during the pesticides application period. Regarding septoria leaf blotch control, good results showed strobilurin alone or in mixture with a triazole, regardless the herbicide that was added to the mixture. The results of this study showed that bromoxynil+2.4-D caused injury when mixed with fungicides and applied under cold temperatures, while one fungicide application at stem elongation provided adequate Septoria leaf blotch control.

Abstract Antimicrobial materials have long been used as an effective means of reducing the risks posed to humans by fungi, bacteria and other microorganisms. These materials are essential in environments where cleanliness, comfort and hygiene are the predominant concerns. This work presents preliminary results for a bactericidal vitreous material that is produced by the incorporation of a silver ionic specimen through ionic exchange reactions. Powdered glass was submitted to ionic exchange in an ionic medium containing AgNO3 as silver ions source. Different AgNO3 concentrations in ionic medium and different particle sizes of the glass were used in the samples development. Microbiological analysis of the samples was made by disk diffusion method in the Escherichia coli and Staphylococcus aureus bacterium species. Samples were still submitted to SEM-EDS, atomic absorption and X-ray diffraction techniques. Results showed that the bactericidal effect was dependent on AgNO3 concentration in the ionic exchange medium, but was not dependent on the particle size of the glass.

Abstract In this work, mesostructured ZSM-5 zeolite was prepared using chitin as a new template to produce mesoporosity. Different amounts of chitin were used for the synthesis of ZSM-5 in order to verify its influence on the formation of mesopores. All samples were prepared by conventional hydrothermal process. For comparison purposes, ZSM-5 zeolite has also been synthesized without a presence of chitin. The samples were characterized by X-ray diffraction, scanning electron microscopy and N2 adsorption techniques. Experimental results showed that the mesopores volume of the obtained samples increased with increasing amount of chitin in the reaction mixture. Therefore, chitin showed to be a promising template for obtaining the ZSM-5 with mesoporous property.

Published: April 2018

Resumo O objetivo deste trabalho foi analisar a passivação de superfícies com SiO2 em células solares bifaciais fabricadas em lâminas finas bem como avaliar a influência do tipo de silício monocristalino utilizado para fabricar as células solares. A estrutura implementada foi a n+pp+, com fósforo na face frontal e boro e alumínio na face posterior, formando uma região seletiva de campo retrodifusor. Foram usadas lâminas de silício Cz (Czochralski) e FZ (float zone) com 145 μm de espessura e implementou-se uma etapa térmica para crescer uma camada de SiO2 para passivar as superfícies. O óxido passivou as superfícies, proporcionando um aumento de 0,5% absolutos na eficiência das células solares fabricadas em silício FZ. As células solares produzidas em Si-Cz não obtiveram o mesmo aumento porque apresentaram uma elevada resistência em série. A célula solar fina mais eficiente foi fabricada com silício FZ e com superfícies passivadas, atingindo eficiência de 14,5% e de 11,1%, para iluminação pela face n+ e p+, respectivamente. As células em Si-Cz, mesmo com menor tempo de vida inicial dos portadores de carga minoritários, atingiram eficiências um pouco menores que estes valores.

Resumo A maquiagem mineral é uma formulação cosmética que traz dentre seus componentes matérias-primas minerais a exemplo dos materiais argilosos, sendo as argilas bentonitas mais comumente utilizadas. O uso de argilas bentoníticas do estado da Paraíba no desenvolvimento de formulações de pó mineral para maquiagem foi o objetivo central deste trabalho. Estas argilas foram estudadas também em sua forma organofílica. Inicialmente foi realizada a caracterização físico-química das argilas bentoníticas naturais e organofilizadas, e os resultados indicaram que as argilas apresentam perfil tecnológico com potencial cosmético. Para formulação cosmética foi utilizado 50% de cada uma das argilas e demais componentes minerais, dando origem a seis diferentes formulações. A partir destas amostras foi estudado seu comportamento estável frente a condições extremas de temperatura. O controle de qualidade toxicológico e microbiológico foi realizado de acordo com os padrões descritos pela Agência Nacional de Vigilância Sanitária (ANVISA) e Farmacopéia Brasileira. As amostras foram testadas para investigação da irritabilidade oftálmica por meio de ensaio in vitro da membrana corioalantóide do ovo da galinha (HET-CAM), e os ensaios microbiológicos foram feitos pelo método de plaqueamento em superfície. Todas as amostras apresentaram-se estáveis quanto às suas características físico-químicas. Nenhuma das formulações apresentou citotoxicidade. O controle microbiológico assegurou a segurança biológica com ausência de bactérias.

RESUMO As órteses são recursos terapêuticos indicados para proteger, corrigir deformidades ou auxiliar em certas funções; porém, seu uso pode acarretar compensações proximais no ombro. O objetivo deste estudo é avaliar a influência da órtese estática dorsal do punho, em 30° de extensão na biomecânica do ombro e cotovelo, em 25 voluntários assintomáticos durante uma tarefa funcional. Os dados da amplitude de movimento e ativação muscular foram adquiridos de forma sincronizada e simultânea durante parte do teste funcional Elui, que simula alimentação, dividida em alcance, deslocamento e liberação, de uma jarra, nas condições sem e com órtese. Para possibilitar a comparação entre os diferentes sujeitos e músculos, os dados foram analisados pela integral do sinal EMG de cada músculo e, para análise cinemática, foram construídos sistemas de coordenadas de marcadores pré-definidos. Os sinais captados foram filtrados e processados por um software personalizado, e utilizou-se o teste t para amostras pareadas - software SPSS, p<0,05. Notou-se um aumento significativo da ativação dos músculos deltoide anterior e peitoral maior na fase de alcance, e trapézio superior, deltoide anterior e posterior na fase de liberação com a órtese. A cinemática mostrou aumento significativo na amplitude de movimento na abdução do ombro, flexão do cotovelo e pronação do antebraço na fase de deslocamento, e dos movimentos extensão do ombro e flexão do cotovelo na fase de liberação. Nossos achados sugerem que o uso da órtese estática do punho durante a execução de uma tarefa pode acarretar compensações, com predomínio da ativação dos músculos mais proximais do membro superior.

ABSTRACT Traumatic brain injury (TBI) is a public health problem with high mortality and socioeconomic repercussions. We aimed to investigate the influence of TBI severity on the length of mechanical ventilation (MV) stay and length of hospital stay and on the prevalence of tracheostomy, pneumonia, neurosurgery and death. This retrospective, observational study evaluated medical records of 67 patients with TBI admitted to Irmandade da Santa Casa de Misericórdia de São Paulo. Severity was determined according to the Glasgow Coma Scale (GCS): mild (13-15 points; 36 patients; 53.7%), moderate (9-12 points; 14 patients; 20.9%) or severe (3-8 points; 17 patients; 25.4%). Severe TBI patients had higher prevalence of tracheostomy, pneumonia and neurosurgery. No significant differences were observed between TBI severity, mortality and length of MV stay. However, TBI severity influenced the length of hospital stay. TBI severity at admission, evaluated according to the GCS, influenced the prevalence of tracheostomy, pneumonia, neurosurgery and was associated to prolonged hospital stay.

As transferências condicionadas de renda na América Latina: lenitivos para a pobreza?
Authors: Espínola Gepherson Macêdo , Zimmermann Clóvis Roberto
Published: April 2018

Resumo Esse texto discute a implementação dos programas de transferências condicionadas de renda na América Latina como estratégia de enfrentamento da pobreza na região. Para tanto, contextualiza sinteticamente o desenvolvimento latino-americano ao longo do tempo, evidenciando através de dados estatísticos não só os elevados índices de pobreza, como também as condições educacionais e de saúde. Estes programas, via de regra, objetivam o alívio e a superação da pobreza, através do repasse monetário e do cumprimento de agendas de saúde e educação que, em tese, aumentariam o capital humano dos pobres e permitiria o ultraje da pobreza no longo prazo. Conclui-se que, apesar de salientes para as famílias, os programas de transferências condicionadas de renda na América Latina, por si sós, ainda não são capazes de enfrentar a pobreza estrutural que assinala a região, promovem o lenitivo para as más condições de vida, sem superá-las.

Published: April 2018

Abstract Procedures used for identifying giftedness have been widely discussed in the literature. The present study aimed to investigate the evidence of validity based on the internal structure of a self-report scale to identify characteristics of giftedness. The sample consisted of 276 Elementary and Middle School students, aged between 9 and 12 years, and was 60.0% female. The instrument used was the first version of this scale, which was composed of 44 items related to the topic. Exploratory Factor Analysis was carried out, and the results revealed a two-factor solution, explaining 40.4% of the total variance. The first factor was denominated Socio-emotional Characteristics, and the second factor was denominated Cognitive Characteristics. The results corroborate the data in the scientific literature, which suggest that giftedness is a multidimensional construct that encompasses attributes that go beyond the intellectual scope.

ABSTRACT Spatial arrangement and population density of component cultures, when well structured, may contribute to increased crop yields relative to monocultures. Thus, the objective of this work was to evaluate the productive performance of carrot and cowpea in an intercropping system under different spatial arrangements and population densities. This research was conducted on the “Rafael Fernandes” experimental farm of the Universidade Federal Rural do Semi-Árido (UFERSA), Mossoró, RN, Brazil. The experimental design was a randomized complete block with four replicates, where the treatments were arranged in a 3 × 4 factorial scheme, in which the first factor was three spatial arrangements (2:2, 3:3, and 4:4) and the second factor was four different population densities of cowpea (100%, 80%, 60%, and 40% of the recommended population in the single crop [RPSC]). Rooster tree Calotropis procera (Ait.) R.Br., a spontaneous species of the „Caatinga‟ biome, was used as fertilizer. The characteristics evaluated in carrot were as follows: total and commercial productivity of roots and classified root production. The following characteristics were evaluated for cowpea: number of pods per square meter, length and yield of green pods, number of grains per pod, 100grain weight, and yield of green grains. The modified monetary advantage was used to evaluate the feasibility of the intercropped systems. Spatial arrangements between the component cultures did not influence the agroeconomic performance of the carrot-cowpea intercropping system. The highest agro-economic performance of the carrot-cowpea intercropping was obtained in the population of cowpea, which was 42% of the RPSC.

ABSTRACT The low use of technologies by farmers and the occurrence of biotic and abiotic stresses are limiting factors for cowpea production in the Brazilian Northeast region. The tolerance of genotypes to drought is an alternative to decrease the negative effects of stresses on cowpea production. Thus, the objective of this work was to identify parents and combinations of cowpea genotypes with high probability of generating segregating populations with tolerance to drought. Six cowpea genotypes were crossed in a complete diallel cross design, totaling 30 F2 populations, which were evaluated together with their parents in an experiment under water deficit at the experimental field of the Embrapa Mid-North, Teresina, State of Piauí, Brazil. A triple lattice incomplete block experiment design was used, with three replications, with experimental plot consisting of six 2-m plant rows. Fifteen plants per plot were sampled to evaluate their agronomic characteristics, whose results were subjected to analysis of variance and means were used to estimate the general and specific combining abilities. The genotypes showed significant differences in all characteristics evaluated, denoting the genetic variability of the population. The additive effects were more important than the non-additive effects, and maternal inheritance was detected. The genotypes BRS Xiquexique, Pingo-de-Ouro-1-2 and MNC99-510F-16-1 were the most promising for use in recurrent selection programs for tolerance to water deficit. The hybrid combinations (1) BRS Paraguaçu X (4) CNCx-698-128G, (2) Pingo-de-Ouro-1-2 X (3) BRS Xiquexique, (3) BRS Xiquexique X (5) Santo-Inácio, (4) CNCx-698-128G X (6) MNC99-510F-16-1 and (5) Santo-Inácio X (4) CNCx-698-128G showed potential for generating superior lineages regarding bean production and tolerance to water deficit.

ABSTRACT Intercropping is a production system that can reduce the production cost and increase the profitability of vegetable producers, since it permits more efficient land and agricultural inputs use. In order to evaluate the effect of lettuce plant density on the economic feasibility of lettuce-rocket intercropping system over two growing seasons (winter and summer), two experiments were conducted in the field at São Paulo State University “Júlio de Mesquita Filho” (UNESP), Jaboticabal, São Paulo, Brazil. The treatments consisted of five lettuce-rocket intercrops with spacing between lettuce rows of: 0.20; 0.25; 0.30; 0.35 and 0.40 m, five sole crop of lettuce in the same spacing between rows adopted in the intercropping system, and a sole cropping of rocket with spacing between rows of 0.20 m. The statistical design adopted was the complete randomized block with four replicates. During winter, higher profitability was achieved with the highest population density. Highest profitability of the crops in both seasons was obtained in summer.

ABSTRACT In Northeast Brazil, the cultivation of colored fiber cotton has stood out as one of the agricultural activities of expressive importance because its fiber has various applications in the industry and it is a labor-demanding crop. In this context, this study aimed to evaluate the growth, water consumption, water use efficiency and production of the colored fiber cotton cv. ‘BRS Rubi’, as a function of saline water irrigation and nitrogen (N) doses. The experiment was conducted in lysimeters, under greenhouse conditions, in eutrophic Regolithic Neosol, with a sandy loam texture, in Campina Grande-PB, Brazil. The plants were irrigated using water with electrical conductivities (ECw) of 5.1, 6.1, 7.1, 8.1 and 9.1 dS m-1 and fertilized with N doses (ND) of 65, 100, 135, 170 and 205 mg N kg-1 soil, in a completely randomized block design, with three replicates. Irrigation using water with an ECw above 5.1 dS m-1, hampered growth, water consumption and water use efficiency of ‘BRS Rubi’ cotton. Among the organs, the cotton root system was less affected by the salt stress in comparison to the shoots. N fertilization did not mitigate the deleterious effect of salt stress on cotton growth, water consumption, water use efficiency and production. The interaction between water salinity and N fertilization had positive effects on total weight of seeds and lint, and the highest values were obtained in plants irrigated with water of ECw 7.6 and 7.5 dS m-1 and ND of 65 mg N kg-1 of soil.

ABSTRACT The objective of this study was to evaluate the productive and economic performance of a forage cactus and sorghum intercropping system in relation to a forage cactus single cropping system under different irrigation blades with saline water. The study was conducted in Serra Talhada, State of Pernambuco, in a randomized block design, consisting of a factorial arrangement with split-plot parcels (5×2) and four replications. The five plots were the irrigation depths based on the reference evapotranspiration (ETo) (0, 8.75, 17.5, 26.25, and 35% ETo) and the two cropping systems were single forage cactus cropping and cactus intercropped with sorghum. The experiment was conducted for one year, with one forage cactus cycle and two cycles of sorghum. Yields were obtained at the end of the cycles. Economic profitability was analyzed by means of net revenue (NR) and the benefit/cost ratio (B/C), with cactus forage sold as forage or as "seed" and sorghum as forage. Net revenue and B/C simulations were carried out over an eight-year useful life span of the irrigation system. Increasing irrigation depth increased the dry matter yield of the intercropping system because of higher sorghum yield. Based on the NR and B/C ratio values, forage cactus and sorghum produced as forage produced higher economic outcomes in the intercropping system and showed a higher profitability from the 2nd year of implementation of the irrigation system. Forage cactus and sorghum intercropping irrigated with saline water is therefore recommended for forage production in the Brazilian semi-arid region.

ABSTRACT The most-used preparation process of protein isolates (PI) involves the isoelectric precipitation of the protein. Heating shortens the preparation time but this procedure may affect the purity, yield, molecular profile of the protein, and the activity of the trypsin inhibitor. This study aimed to investigate the effect of heating in the production of cowpea protein isolates. Crude whole beans (WB) were defatted with hexane, and the protein isolates obtained by isoelectric precipitation with (HPI), and without (NHPI) heating. The protein content of the WB and the PI was determined by the micro-Kjeldahl method, and the extraction yield estimated from the protein content at the end of extraction in relation to this content in the raw material. Possible losses of protein fractions were followed by SDS-PAGE, and the trypsin inhibitor activity determined by an enzymatic assay (BAPNA: benzoyl-DL-arginine-p-nitroanilide). Protein content in HPI was 83.3%, less than in the NHPI (92.2%). The HPI yield was lower (40.0%) as compared to the NHPI (42.3%). Electrophoresis indicated bands ranging from 13 to 262 kDa in WB; and the NHPI presented a protein fraction’s profile closer to that of the WB than to the HPI. The WB had the trypsin inhibitor activity, expressed as Trypsin Inhibitory Units (TIU), of 32.5±0.5 TIU /mg-protein; HPI showed 12.7±0.5 TIU /mg-protein (39% of that observed in WB) and the NHPI, 8.3±0.2 TIU /mg-protein (25.5%). Heating reduces the yield and purity of proteins in the isolates. However, the inhibitory activity of trypsin cowpea is most affected by the isolation procedure.

ABSTRACT Flour production through milling is an alternative for the cowpea processing, when the aim is to obtain a product with higher added value. The objective of this work was to determine the chemical composition, the granulometry, and evaluate the microbiological characteristics of whole-bean flours from five cowpea cultivars (BRS Cauamé, BRS Guariba, BRS Xiquexique, BRS Novaera and BRS Itaim). Cowpea beans were dried in a oven (Fanem, 320-SE) at 50 °C for 6 hours, milled in a cyclone-type rotor mill (Tecnal, TE-651/2) and, subsequently, in a pulverizer-type semi-industrial mill (Fritsch, Pulverisette 14) to obtain the flour. The flour centesimal composition, total energetic value, mineral content, granulometry, microbiological characteristics, and technological properties-flour water absorption and solubility in water-were analyzed. All analyzes were performed in triplicate and the results expressed in mean ± standard deviation. The means were compared by the Scott-Knott test (p ≤ 0.05). The flour centesimal composition presented (g per 100 g of flour): 7.13 to 10.33 of moisture, 2.06 to 3.65 of ashes, 1.53 g to 2.90 of lipids, 21.73 to 25.77 of proteins, and 58.08 to 64.02 of carbohydrate. The flours had on average 359.04 Kcal (100 g) and presented high iron, zinc, copper, manganese, phosphorus and magnesium contents. The whole-bean flours from the cultivars BRS Cauamé and BRS Xiquexique are sources of calcium. Regarding the microbiological characteristics, all flours are innocuous. The water absorption index were within 1.77 and 2.20 g g-1 and the water solubility index within 17 and 23%. All whole-bean flours had good nutritional, technological and microbiological characteristics, and thus potential for use in bakery products.

ABSTRACT Nitisols are livelihood sources of agricultural and socio-economic development in several underdeveloped countries worldwide, including Brazil. Brazilian Nitisols are usually associated with basaltic rocks found in the Southern and Southeastern regions of the country. However, Nitisols derived from basalt also occur on the southern coast of Pernambuco state, a region under full urban, agricultural, and industrial development. Aiming to understand the relationship between climate and attributes of Nitisols from the southern coast of Pernambuco, we performed morphological descriptions, physical and chemical analyzes, iron selective extraction, and soil mineralogy (sand, silt, and clay) for three basaltic soil profiles along a land slope. The results suggest a strong weathering of the profiles due to climate conditions, besides a great loss of basic cations and xanthization process, resulting in the natural genesis of acric Nitisols with yellowish coloration, which has not been yet cataloged for this soil order in the Brazilian taxonomic system. In addition, there is a variation for physical attributes of Nitisols along the slope.

Authors: Souza Angela Alves Correia de , Cintra Raquel Barbosa
Published: April 2018

Resumo Violência doméstica é o tipo mais comum de violência contra a mulher e resulta em sequelas nas esferas física, emocional, familiar e econômica, constituindo problema de saúde pública. Porém, a questão é tratada de maneira negligente pelos profissionais de saúde, o que contribui para sua invisibilidade. Baseado em revisão da literatura, este estudo objetivou identificar as principais dificuldades, incluindo conflitos éticos, encontradas pelos médicos na abordagem de pacientes vítimas desse tipo de violência. Os obstáculos elementares foram agrupados em três grandes eixos: questões relacionadas ao profissional de saúde; estrutura do sistema de saúde; e aspectos das vítimas de violência. Concluiu-se que o maior entrave advém do próprio profissional de saúde e envolve fatores que variam desde formação inadequada até a ocorrência de conflitos morais e éticos que culminam na culpabilização e responsabilização das vítimas pela situação de violência em que se encontram.

Estéticas da Carne: insurreições curriculares do corpo feio
Authors: Roseiro Steferson Zanoni , Rodrigues Alexsandro , Alvim Davis Moreira
Published: April 2018

Resumo: O artigo objetiva pensar a existência de um corpo feio como insurreição curricular frente às estratégias de embelezamento capitalísticos e aposta na possibilidade de indagar as belezas. Apesar de toda uma política organizacional curricular que enaltece o corpo asséptico, belo e convidativo, propõe-se pensar o corpo para além da servidão estética capitalística. Se o imperativo é estético, ela faz zombaria na feiura.

Published: April 2018

Abstract Objective To adapt and validate a widely used set of moral dilemmas to European Portuguese, which can be applied to assess decision-making. Moreover, the classical formulation of the dilemmas was compared with a more focused moral probe. Finally, a shorter version of the moral scenarios was tested. Methods The Portuguese version of the set of moral dilemmas was tested in 53 individuals from several regions of Portugal. In a second study, an alternative way of questioning on moral dilemmas was tested in 41 participants. Finally, the shorter version of the moral dilemmas was tested in 137 individuals. Results Results evidenced no significant differences between English and Portuguese versions. Also, asking whether actions are “morally acceptable” elicited less utilitarian responses than the original question, although without reaching statistical significance. Finally, all tested versions of moral dilemmas exhibited the same pattern of responses, suggesting that the fundamental elements to the moral decision-making were preserved. Conclusions We found evidence of cross-cultural validity for moral dilemmas. However, the moral focus might affect utilitarian/deontological judgments.

Published: April 2018

ABSTRACT Wild mustard plant (Sinapis arvensis), Brassicaceae, is a wild vegetable found in forest area, domestic orchards and it is consumed by rural population. This study aimed to evaluate chemical composition (moisture, total dietary fiber, lipids, proteins, ash, carbohydrates and total energetic value), concentration of carotenoids, vitamins (C and E) and minerals (K, Ca, Mg, Cu, Fe, Zn, Mn, Na, Cr, Se and Mo) and the contribution by this vegetable to the recommendations of daily consumption of nutrients for adult individuals. Concentrations of provitamin A (252.21 RAE/100 g), Se (0.04 mg/100 g) and Fe (5.91 mg/100 g) stood out, in which this vegetable was considered as an excellent source for these nutrients. In addition, wild mustard was considered a good source of K (435.65 mg/100 g), Ca (123.25 mg/100 g) and Mn (0.40 mg/100 g) and source of Total Dietary Fiber (TDF) (3.20 mg/100 g), Mg (26.82 mg/100 g) and Cu (0.07 mg/100 g). Wild mustard stood out as source, good source or excellent source of the evaluated nutrients, and they may contribute to reduce nutritional deficiency of those nutrients in the populations living in the region where this vegetable occurs.

ABSTRACT The aim of this study was to evaluate the effect of light quality and nitrogen availability on the biomass production, yield and composition of essential oil of lemon balm (Lippia alba). Five doses of N (0; 40; 80; 120 and 160 kg ha-1) were studied, using urea and three light quality conditions obtained with the use of colored shading nets (blue and red), 50% irradiance and under full sun. The experiment was arranged in a 5x3 factorial scheme, in split plots, with seven replicates. After 60 days of cultivation under the shading nets, a higher dry leaf biomass (4.83 g per plant) was observed in the plants under blue net cultivation at a dose of 102 kg ha-1 of N. The plants grown under full sun presented greater amount of neral and geranial, major components of the essential oil of the lemon balm, which give commercial value to the species. The use of colored shading nets does not influence the composition of the essential oil of lemon balm, but increases the concentration of the compounds found in it. Nitrogen does not affect the quality of the essential oil of lemon balm, but it provides higher oil yield (0.27 g per plant) at the dose of 65 kg ha-1 of N.
