title: Reaction of weeds, found in vegetable production areas, to root-knot nematodes Meloidogyne incognita and M. enterolobii

description: ABSTRACT Root-knot nematodes cause great damage to vegetable crops in Brazil, besides having a large range of host plants, such as weeds. Weeds can maintain the inoculums or even favor the multiplication of these nematodes. In this study we evaluated the reaction of selected weed species, present in a vegetable production area, to root-knot nematodes Meloidogyne incognita and M. enterolobii. The trials were conducted in a greenhouse at Embrapa Hortaliças, Brasília-DF, in a completely randomized design with six replicates. Fifteen weed species were evaluated for M. incognita race 1, and 16 weed species were evaluated for M. enterolobii. Two tomato cultivars were evaluated as resistance and susceptibility standards. Gall index (IG), egg mass index (IMO), number of eggs per gram of roots (eggs/g roots) and reproduction factor (FR) were evaluated. M. enterolobii survives and multiplies more easily in weeds collected in vegetable production areas than M. incognita race 1 and, the great majority of weed species evaluated in this study are hosts of both nematode species. Only the species Urena lobata, Sonchus oleraceus, Euphorbia heterophylla, Melampodium perfoliatum and Tagetes sp. were immune to M. incognita race 1. All evaluated species are either hosts or favor the multiplication of M. enterolobii. The species which are the most susceptible to M. incognita race 1, and therefore require greater control of crops infected by this nematode are Ipomoea nil, I. triloba and Eleusine indica, and for M. enterolobii are I. nil, Solanum americanum, Hyptis suaveolens, Portulaca oleracea, I. triloba and Euphorbia heterophylla.

title: Tracing the material history of MAC USP’s Self-Portrait by Amedeo Modigliani

description: ABSTRACT This two-part article (history and analysis, followed by the interpretation of data obtained via analytical techniques) is a study of Amedeo Modigliani’s Self-Portrait (1919, oil/canvas, 100 x 65 cm2), which belongs to the Museu de Arte Contemporânea of the Universidade de São Paulo (MAC USP). By collating documentation on the work’s provenance, critical sources regarding Modigliani’s approach to painting, and technical-scientific (physicochemical and imaging) analyses, we were able to reassess it in light of the articulation between the work’s materiality and composition. We also managed to throw new light on the work’s critical reception in the 1950s, when it arrived in Brazil and received international exposure - at that time, already part of a Brazilian collection - by means of publications and exhibitions.

title: Training systems and rootstocks on yield and agronomic performance of ‘Syrah’ grapevine in the Brazilian semiarid

description: ABSTRACT The Vale do São Francisco stands out among the main Brazilian wine regions, and ‘Syrah’ is a grape cultivar very important to produce red wines. The objective of this study was to evaluate the influence of training systems and rootstocks on the yield and other agronomic variables of ‘Syrah’ grapevines during eight consecutive harvests in the tropical semiarid environment in the Vale do São Francisco. An experiment was carried out in Petrolina, state of Pernambuco, with ‘Syrah’ trained to lyre and espalier systems and grafted on IAC 572, IAC 766, IAC 313, SO4, 1103 Paulsen and Harmony rootstocks. A randomized block design with four replicates and split plots was used. There was a significant interaction between the training system and rootstock for yield, number of clusters and foliar mass. The lyre system increased yield, cluster number and Ravaz index, favoring the development of more balanced grapevines. The IAC 572 rootstock promoted greater vigor by reducing yield, cluster number, bud fertility and Ravaz index. The other rootstocks were similar to each other in most variables. Net photosynthesis, stomatal conductance and instantaneous efficiency of water use were not influenced by the training system and the rootstock. The results obtained evidenced the influence of the training system associated to the rootstock on agronomic variable and yield of ‘Syrah’, recommending lyre training and grafting on 1103 Paulsen or IAC 313 in the semi-arid tropical conditions of the Vale do São Francisco.

title: Revealing Hercule Florence, Friend of the Arts: X-ray Fluorescence Analysis

description: ABSTRACT The debates about Hercule Florence (Nice, France, 1804 - Campinas, SP, 1879) as the pioneer in the discovery of the photographic process were based mainly on his manuscripts, since few of his épreuves photographiques (photographic experiments) survived. Technological advances in the last four decades have allowed some of his impressions à la lumière solaire to be subjected to analysis by non-destructive techniques at the Instituto de Física of the Universidade de São Paulo in 2016. It was then possible to broaden knowledge of the materials and procedures used in 1833 to obtain the first photographs of the Americas, six years before the announcement of the discovery of the technique by Louis Daguerre in France.

title: Sucrose concentration and volume of liquid medium on the in vitro growth and development of blackberry cv. Tupy in temporary immersion systems

description: ABSTRACT Micropropagation of small fruits such as blackberry has been employed due to the need to obtain plants with high phytosanitary quality. Bioreactor technology has been used to improve efficiency in seedling production. Thus, the objective of this work was to evaluate the best culture medium volume and sucrose concentration for blackberry micropropagation in a temporary immersion bioreactor. In vitro blackberry shoots were segmented containing two buds and an internode (1.0 cm) and placed into MS medium supplemented with inositol (0.1 g L-1), BAP (1 mg L-1) and sucrose (10, 20, 30 or 40 g L-1) at different medium volumes (150, 175 and 200 mL). The total length, number of leaves, number of shoots, and number of hyperhydric shoots were evaluated 56 days after start of the project. For blackberry development and propagation in a bioreactor system, the best results were shown at a medium volume of 175 ml and a sucrose concentration of 20 g L-1.

title: Applications of archeometry in eighteenth century São Paulo furniture: indicative analysis and historical contextualization

description: ABSTRACT This article presents the results of applied Physics archeometric measurements on two pieces of furniture from the Museu Paulista collection, a chest-safe and a tanned leather chair, both made around the eighteenth century. The analysis techniques used were ED-XRF and imaging with ultraviolet light fluorescence. The interdisciplinary analyses sought to identify the materials with which the pieces were composed, thus presenting historical information about furniture production in the city of São Paulo in the eighteenth century. The obtained results allowed the identification of some of the materials used in the painting of the chest-safe - white lead and vermilion (or cinnabar) - and in the tanned leather and metal parts of the chair - iron and brass in both parts -, although additional procedures still need to be applied for obtaining results on other materials. To allow the contextualization of the material and economy life of São Paulo, the information obtained from material sources were confronted with broader textual documentation data such as paint commission lists, travel reports and artistic manuals of the time, thus revealing the city’s dynamism and its intricate commercial networks.

title: Soybean yield in the Matopiba region under climate changes

description: ABSTRACT The climatic conditions along the cycle are the main factors responsible for the final production of any crop. This study aimed to evaluate the current conditions and the effects of climate change scenarios on the yield of soybean grown in the Matopiba region, located between the states of Tocantins, south and northeast of Maranhão, south of Piauí and west of Bahia, Brazil. The AquaCrop model of FAO, version 5.0, was calibrated with data of 2014 and validated with those of 2016, using climate, soil and crop management parameters collected in two experimental campaigns conducted between June and October in 2014 and 2016 in Palmas, TO, Brazil. The performance of the model was evaluated using the following statistical indicators: prediction error (PE), coefficient of determination (R2), normalized root mean square error (NRMSE), Nash-Sutcliffe model efficiency coefficient (EF) and Willmott’s index of agreement (d). It was verified that the AquaCrop model underestimates soybean grain yield under severe water stress conditions throughout the growing cycle. The increase in CO2 concentration and in the air temperature, projected by the climate models HadGEM2-ES and MIROC5 under the scenario of stabilization (RCP 4.5) and the scenario of progression (RCP 8.5), have contributed to the increase in soybean yield by the end of this century.

title: Characterization of pericarp fractions of yellow passion fruit: density, yield of flour, color, pectin content and degree of esterification

description: Abstract The pericarp of passion fruit can be processed to be used as a new ingredient in the food industry, or as source of pectin. Pericarp samples were taken with a 5 mm cylindrical metal probe to measure the apparent density. Pericarp fractions of eighty fruits at three maturation stages were dried and their flours were quantified and evaluated by instrumental color. The pectin was extracted and its degree of esterification (DE) was quantified. The yield of flour of epicarp and mesocarp reached 3.4% and 4.6% (dry basis) at different maturation stages of passion fruit, respectively. The content of pectin was higher in mesocarp flour, also, its DE increased deeply with the fruit maturation. The mesocarp with the lower density can be separated from the epicarp in a water flow system, which allows the production of clearer flour with the highest content of pectin and the highest DE in ripe fruits.

title: Incorporation of graphene oxide in coating mortar: a sustainable view

description: Abstract Nanotechnology has greatly developed in recent years, promoting the emergence of new materials, such as graphite and its compositions as graphene oxide and graphene. This study performs a physical, chemical and mechanical evaluation of a coating mortar with graphene oxide incorporation at the proportions of 0.04% and 0.1%. The addition caused minimal interference in the physical properties of graphene oxide-containing mortars, when compared to the reference mortar, without compromising the final mortar. However, with regards to the mechanical properties, there was an increase in the compressive strength of modified mortars when compared to the reference mortar and the desirability function determined that with 82.45% of optimisation, the proportion of 0.1% contributed to improve the conditions for compressive strength and flexural tensile strength of modified mortars. The image analyses also corroborated with this fact, as it was possible to see that when there was better dispersion of graphene oxide on the cementitious matrices, the mechanical properties also improved.

title: Relationship between elderly stroke patient caregivers scale and nursing diagnoses

description: ABSTRACT Objective: To describe relationships between the ECPICID-AVC scale factors and the NANDA-I domains, classes, and Nursing Diagnoses (NDs). Method: Cross-mapping study between the NANDA-I taxonomy and ECPICID-AVC scale was constructed based on the eight ECPICID-AVC scale factors and the 13 NANDA-I domains. A descriptive analysis was performed to present the mapped elements. Results: Areas of similarity and intersection were found between the eight ECPICID-AVC factors and nine NANDA-I domains, 19 classes, and 72 NDs. All scale factors were mapped with the Domain 1/Health Promotion, Class 2/Health Management and the ND “Frail elderly syndrome”. Final considerations: The ECPICID-AVC scale factors were mapped with nine domains, their classes and diagnoses. This study demonstrates the importance of identifying nursing diagnoses and their relationship with factors that evaluate caregiving capacity. The ECPICID-AVC can help nurses generate nursing diagnoses regarding the caregiver’s needs and their capacities related to care to focus such needs.

title: LIPASE - CATALYZED FORMATION OF PENTYL NONANOATE USING SCREENED IMMOBILIZED LIPASE FROM Rhizomucor meihei

description: Abstract Bio-catalysis has attracted the special attention of industrial flavour producers in the production of valuable ester compounds. In this study, the synthesis of pentyl nonanoate ester (a short chain ester with fruity aroma) was carried out with a commercial immobilized lipase from Rhizomucor meihei Lipozyme (RMIM) as biocatalyst in the esterification reaction between nonanoic acid and pentanol. Various reaction parameters such as enzyme concentration, substrate concentration, reaction temperature and reaction time in solvent-free system were screened to enhance the ester formation with the best yield. A maximum yield for pentyl nonanoate (86.08 %) in a solvent-free system was obtained within 150 min, at a reaction temperature of 45 OC, molar ratio of 1:9 M, amount of enzyme of 0.2 g, water addition of 0.2 % v/v and shaking speed of 150 rpm. This work suggests that pentyl nonanoate ester can be produced in a very high yield and in a short period by lipase-catalysed reactions of nonanoic acid and pentanol, using immobilized lipase from RMIM (lipase from Rhizomucor miehei immobilized on anionic exchange support).
