Development and production of iceberg lettuce irrigated with magnetically treated water

Irrigated agriculture has become a concern, given the scarcity of freshwater. To reduce its water consumption, new techniques and technologies have been proposed. Based on this, the objective of this work was to evaluate the influence of different soil water tensions at initiation of irrigation with magnetically treated water, on ‘iceberg’ lettuce Lucy Brown (Lactuca Sativa L.) development and production. The experiment was conducted in a greenhouse, using a completely randomized factorial design, to evaluate two water types (magnetically treated water – MW and ordinary water – OW) and four soil water tensions at initiation of irrigation (T1 – 15 kPa, T2 – 25 kPa, T3 – 40 kPa and T4 – 70 kPa), with three replicates. Tnsiometers were used to estimate soil water tension. The evaluated parameters were: aerial part fresh and dry total mass; commercial head fresh and dry mass, root fresh and dry mass; stem fresh and dry mass; stem length and diameter; percentage of leaves with tip burn, total and commercial yield; water use efficiency related to total and commercial yield; plant exposed area; and dry matter content. Despite achieving greater water use efficiency, the magnetic treatment may have hindered the removal of water from the soil by the crop, especially at increased soil water tension at initiation of irrigation

Occurrence of antibodies to Toxoplasma gondii in opossums caught in urban areas of Bauru, state of São Paulo, Brazil

Toxoplasmosis is one of the most common zoonoses worldwide. It was initially described in rodents and rabbits. There are few data on the morbidity and mortality of this disease among Brazilian marsupial fauna, such as opossums. These animals are of great importance regarding the epidemiology of this disease, given that they are prey for felids and other carnivores. With the aim of ascertaining the serological response to Toxoplasma gondii among marsupials (Didelphis spp.), 38 animals that had been caught in 14 districts of the urban area of the municipality of Bauru, state of São Paulo, were evaluated. The modified agglutination test (MAT) showed that 26.3% (10/38) of the samples analyzed were seropositive. It can be suggested that the opossums’ behavior and persistent proximity to human housing results in contact with cats and T. gondii infection, based on the frequency found in this study. This was the first study on the seroprevalence of T. gondii in opossums caught in the urban area of the municipality of Bauru, SP, and it highlights the need for environmental and health authorities of the municipality to monitor this zoonosis. A toxoplasmose é uma das zoonoses mais comuns no mundo, tendo sido descrita inicialmente em roedores e em coelhos. Todavia, poucos são os dados sobre morbidade e mortalidade da toxoplasmose nos marsupiais da fauna brasileira, como os gambás, sendo de grande importância na epidemiologia da doença, como presas para felídeos e outros carnívoros. Com o objetivo de verificar a resposta sorológica para Toxoplasma gondii em marsupiais (Didelphis spp.), foram avaliados 38 animais capturados em 14 regiões da área urbana do município de Bauru-SP. Foi encontrada uma frequência, de acordo com o teste de aglutinação modificada (MAT), de 26,3% (10/38) nas amostras analisadas. Pode-se sugerir que o comportamento dos gambás e sua permanência próxima a habitações humanas resultam em contato com gatos e infecção por T. gondii, tendo em vista a frequência encontrada neste estudo. Este é o primeiro estudo de soroprevalência de T. gondii em gambás capturados na área urbana do município de Bauru-SP, alertando-se para a necessidade do monitoramento desta zoonose pelas autoridades de vigilância ambiental e sanitária do município

Características vegetativas e produtivas de cafeeiro em diferentes supressôes de irrigação e faces de exposição

The objective of this study was to verify the initial effects of different deletions of irrigation on vegetative and productive characteristics of coffee after pruning. The experiment in split plot design with four replications in a randomized complete block design was conducted at Fazenda Cambuhy Agrícola Ltda (Matão, state of São Paulo), with arabica cultivar Mundo Novo IAC 376-4, in a drip system in the 2010/2011 season. For the vegetative characteristics, primary treatment consisted of six deletions irrigation NI = not irrigated, IC = continuous irrigation throughout the year, IC = IC 14a-19m, except between April 14 to May 19, IC-20m 24jn = IC, except between May 20 to June 24, IC-25jn 30jl = IC, except between June 25 to July 30 and IC = IC 31jl-04s, except between July 31 to September 4. Secondary treatments mentioned up to six evaluation periods. For production traits primary treatments were deletions in irrigation treatments and the secondy treatment checks for side of plant exposure to solar radiation Southeast (SE) and northwest (NW). We evaluated the vegetative characteristics and canopy stem diameter, plant height and insertion of the first branch, number of branches and length of branches (SE, NW and middle). The total productivity of coffee and enjoyed the “floor”, crop yield, income benefit and weight of 100 grains was evaluated on each face exposure. The non-irrigated coffee has the lowest increase in initial growth after pruning, except for insertion height of the 1st. plagiotrophycal. In irrigated coffee throughout the year, the lowest increase in the initial growth occurs with greater suppression IC 25jn-30jl e IC 31jl-04s, during the spring and summer, except for the canopy diameter. In irrigated coffee trees, especially the use of deletions IC 20m-24jn, and IC-25jn 30jl, higher overall productivity and income benefit of coffee occurs, compared to non-irrigated coffee. The northwest face of plant exposure to solar radiation provides higher total yield and yield of coffee.Objetivou-se, neste trabalho, verificar os efeitos iniciais de diferentes supressões de irrigação e faces de exposição solar sobre as características vegetativas e produtivas de cafeeiros após a poda. O experimento no delineamento em parcelas subdivididas com quatro repetições, em blocos casualizados, foi conduzido na Fazenda Cambuhy Agrícola Ltda (Matão, SP), com a cultivar arábica Mundo Novo IAC 376-4, em sistema de gotejamento na safra 2010/2011. Para as características vegetativas, os tratamentos primários constituíram-se em seis supressões de irrigação NI= não irrigado, IC=irrigação continuada durante todo o ano, IC 14a-19m= IC, exceto entre 14 de abril a 19 de maio, IC 20m-24jn= IC, exceto entre 20 de maio a 24 de junho, IC 25jn-30jl= IC, exceto entre 25 de junho a 30 de julho e IC 31jl-04s= IC, exceto entre 31 de julho a 04 de setembro. Os tratamentos secundários referiram-se a seis épocas de avaliação. Para as características produtivas os tratamentos primários constituíram-se nas supressões de irrigação e os tratamentos secundários nas faces de exposição das plantas à radiação solar Sudeste (SE) e Noroeste (NW). Avaliaram-se as características vegetativas diâmetro de caule e copa, altura da planta e inserção do primeiro ramo, número de ramos e o comprimento de ramos (SE, NW e média). Foi avaliada em cada face de exposição a produtividade total do café beneficiado e café de “chão”, rendimento da lavoura, renda de benefício e massa de 100 grãos. O cafeeiro não irrigado apresenta o menor incremento no crescimento inicial após a poda, exceto para altura de inserção do 1º ramo plagiotrópico. No cafeeiro irrigado, durante todo o ano, ocorre menor incremento no crescimento inicial sendo maior na supressão IC 25jn-30jl e IC 31jl-04s, durante o período de primavera e verão, exceto para o diâmetro de copa. Nos cafeeiros irrigados, em especial pelo uso das supressões IC 14a-19m, IC 20m-24jn, e IC 25jn-30jl, ocorre maior produtividade total e renda de benefício de café, comparado ao cafeeiro não irrigado. A face noroeste de exposição das plantas à radiação solar proporciona maior produtividade total e rendimento de café

Desenvolvimento vegetativo do tomateiro sweet heaven irrigado com água tratada magneticamente / Vegetative development of sweet heaven tomato irrigated with magnetically treated water

Atualmente estudos científicos têm mostrado benefícios no desenvolvimento de culturas quando irrigadas com água tratada magneticamente. Assim, objetivou-se avaliar os benefícios da irrigação com este tratamento de água nas características de crescimento (altura de planta e diâmetro de caule) do tomate tipo cereja, híbrido Sweet Heaven. O experimento foi conduzido em casa de vegetação no campo experimental da UFLA, em Lavras – MG, no período entre 13/02/2017 e 27/07/2017. Os tratamentos foram compostos por cinco  percentuais de volume de reposição de água de irrigação (30%; 60%; 90%; 120% e 150% do volume de evapotranspirado da cultura - V) combinados com dois tipos de água (tratada magneticamente e não tratada), dois tipos de substrato (fibra de coco e solo) e sete repetições. O efeito sobre a altura de planta foi estatisticamente significativo somente para o tipo de substrato, com destaque para o cultivo em solo (228,61 cm). Por outro lado, os efeitos sobre o diâmetro de caule foram significativos para lâmina de irrigação, tipo de substrato e tipo de água. Verificou-se que o cultivo de tomateiro em substrato fibra de coco, irrigado com água tratada magneticamente teve desenvolvimento de caule superior

Synthesis and biological evaluation of novel imidazolidine derivatives as candidates to schistosomicidal agents

Introduction: Schistosomiasis is an infectious parasitic disease caused by trematodes of the genus Schistosoma, which threatens at least 258 million people worldwide and its control is dependent on a single drug, praziquantel. The aim of this study was to evaluate the anti-Schistosoma mansoni activity in vitro of novel imidazolidine derivatives. Material and methods: We synthesized two novel imidazolidine derivatives: (LPSF/PTS10) (Z)-1-(2-chloro-6-fluorobenzyl)-4-(4-dimethylaminobenzylidene)-5-thioxoimidazolidin-2-one and (LPSF/PTS23) (Z)-1-(2-chloro-6-fluoro-benzyl)-5-thioxo-4-(2,4,6-trimethoxy-benzylidene)-imidazolidin-2-one. The structures of two compounds were determined by spectroscopic methods. During the biological assays, parameters such as motility, oviposition, mortality and analysis by Scanning Electron Microscopy were performed. Results: LPSF/PTS10 and LPSF/PTS23 were considered to be active in the separation of coupled pairs, mortality and to decrease the motor activity. In addition, LPSF/PTS23 induced ultrastructural alterations in worms, after 24 h of contact, causing extensive erosion over the entire body of the worms. Conclusion: The imidazolidine derivatives containing the trimetoxy and benzylidene halogens showed promising in vitro schistosomicidal activity

Pervasive gaps in Amazonian ecological research

Biodiversity loss is one of the main challenges of our time,1,2 and attempts to address it require a clear un derstanding of how ecological communities respond to environmental change across time and space.3,4 While the increasing availability of global databases on ecological communities has advanced our knowledge of biodiversity sensitivity to environmental changes,5–7 vast areas of the tropics remain understudied.8–11 In the American tropics, Amazonia stands out as the world’s most diverse rainforest and the primary source of Neotropical biodiversity,12 but it remains among the least known forests in America and is often underrepre sented in biodiversity databases.13–15 To worsen this situation, human-induced modifications16,17 may elim inate pieces of the Amazon’s biodiversity puzzle before we can use them to understand how ecological com munities are responding. To increase generalization and applicability of biodiversity knowledge,18,19 it is thus crucial to reduce biases in ecological research, particularly in regions projected to face the most pronounced environmental changes. We integrate ecological community metadata of 7,694 sampling sites for multiple or ganism groups in a machine learning model framework to map the research probability across the Brazilian Amazonia, while identifying the region’s vulnerability to environmental change. 15%–18% of the most ne glected areas in ecological research are expected to experience severe climate or land use changes by 2050. This means that unless we take immediate action, we will not be able to establish their current status, much less monitor how it is changing and what is being lostinfo:eu-repo/semantics/publishedVersio

Search for Physics beyond the Standard Model in Events with Overlapping Photons and Jets

Results are reported from a search for new particles that decay into a photon and two gluons, in events with jets. Novel jet substructure techniques are developed that allow photons to be identified in an environment densely populated with hadrons. The analyzed proton-proton collision data were collected by the CMS experiment at the LHC, in 2016 at root s = 13 TeV, and correspond to an integrated luminosity of 35.9 fb(-1). The spectra of total transverse hadronic energy of candidate events are examined for deviations from the standard model predictions. No statistically significant excess is observed over the expected background. The first cross section limits on new physics processes resulting in such events are set. The results are interpreted as upper limits on the rate of gluino pair production, utilizing a simplified stealth supersymmetry model. The excluded gluino masses extend up to 1.7 TeV, for a neutralino mass of 200 GeV and exceed previous mass constraints set by analyses targeting events with isolated photons.Peer reviewe
