title: Clientele profile of early intervention services: a focus on eye health

description: Abstract Objectives: To describe and analyze the profile of children with developmental disorders treated at early intervention services (IP) and their mothers or caregivers, focusing on aspects related to the child's ocular health. Methods: Quantitative survey, exploratory-descriptive. The data collection instrument consisted of a questionnaire applied with mothers or caregivers of children assisted in IP services. The data were transcribed in Microsoft Excel spreadsheet and analyzed based on simple descriptive statistics. The sample consisted of 273 subjects. Results: There was a prevalence of mothers (84.2%) between 30 and 40 years old (38.8%). The children were between 1 and 2 years of age (34.8%), and, for the most part, with Down's Syndrome (26.7%). The mean age of entry of children in IP services was 7.93 months and the age at first consultation with the ophthalmologist - of those who had already performed (82.8%) - was 6.8 months, with 45,6% presented ophthalmological alterations, predominating strabismus (40.8%). Conclusions: The results obtained allowed the identification and characterization of mothers or caregivers and children attending IP services, especially in questions related to ocular health. Understanding this scenario should support actions aimed at ocular health education, prevention and rehabilitation and should be directed to IP services, managers, families and children.

title: Methods of adaptability and stability applied to eucalyptus breeding

description: Abstract: The objective of this work was to evaluate the consistency of the methods of Annicchiarico, Lin & Binns, Wricke, and factor analysis in identifying eucalyptus clones with stability, adaptability, and high productive potential. Eight-four clones, with three years of age, from the genetic breeding program of the company CMPC Celulose Riograndense were used. Three field experiments were carried out in a randomized complete block design, in an 84x3 factorial arragement, with 20 replicates of one plant per plot. The clones were evaluated as to diameter at breast height, plant height, and volume of wood. The methods of Annicchiarico and Lin & Binns are highly correlated with each other, and their use together with the method of Wricke is a sound strategy for the evaluation of eucalyptus clones. The factor analysis identified broadly adaptable clones, and some of them were the same ones identified by the methods of Annicchiarico and Lin & Binns. The use of the mean classification of the clones, along with the factor analysis, is efficient to identify the most adapted, stable, and productive ones among a high number of genotypes.

title: Agronomic performance of Italian zucchini as a function of phosphate fertilization

description: ABSTRACT The objective of this research was to evaluate the agronomic performance of Italian zucchini as a function of phosphate fertilization. The experiments were carried at the Rafael Fernandes Experimental Farm, Federal Rural University of the Semi-Arid Region, Mossoró, RN, Brazil, from August to November 2015 and from July to September 2016. The experimental design was randomized blocks in 2 x 5 factorial scheme, with four replicates. The treatments consisted of the combination of two cultivars (Caserta and Alícia) and five doses of phosphorus (0, 40, 78, 120 and 150 kg ha-1 of P2O5). Phosphorus doses associated with the maximum marketable yields estimated were smaller for Alícia than for Caserta in the period from August to November 2015. In the period from July to September 2016, these estimated doses were higher for Alícia compared with Caserta. Alícia, regardless of crop season, was superior to Caserta. Zucchini cultivation from July to September of 2016 resulted in higher fruit yield in comparison to the period from August to November 2015.

title: Agronomic characteristics of common bean and castor bean hybrids in intercropping and monocropping

description: ABSTRACT Common bean has great importance in the Brazilian economy and castor bean is still emerging in Midwestern Brazil, but with great potential of exploitation by farmers due to the prevailing climatic conditions and flat topography. Hence, this study aimed to evaluate the agronomic characteristics of common bean cultivars and castor bean hybrids in intercropping and monocropping under the edaphoclimatic conditions of the Cerrado region. The randomized block design was used in 4 x 2 + 6 factorial scheme, with three replicates. Treatments were composed of four cultivars of common beans (BRS Pérola, BRS Esteio, BRSMG Realce and BRS Pitanga) intercropped with two castor bean hybrids (Tamar and Ag Ima), plus the respective crops in monocropping. In common bean cultivars, plant height was influenced in the intercropping with castor bean hybrids; however, agronomic characteristics of the castor bean hybrids were not influenced by common bean cultivars. The intercropping between common bean cultivars (BRS Esteio, BRSMG Realce and BRS Pitanga) and castor bean hybrids (Tamar and Ag Ima) was classified as viable by the area equivalence index, since this index presented values greater than 1.0 for the intercropping between these cultivars. This fact indicates that it would take more than one hectare in monocropping to produce the same amount than one hectare in intercropping.

title: Clay Mineralogy of Basaltic Hillsides Soils in the Western State of Santa Catarina

description: ABSTRACT A commonly accepted concept holds that highly fertile, shallow soils are predominant in the Basaltic Hillsides of Santa Catarina State, in southern Brazil, but their agricultural use is restricted, either by excessive stoniness, low effective depth or steep slopes. Information about soil properties and distribution along the slopes in this region is, however, scarce, especially regarding genesis and clay fraction mineralogy. The objective of this study was to evaluate soil properties of 12 profiles distributed in three toposequences (T) of the Basaltic Hillsides in the State of Santa Catarina, two located in the valley of the Peixe River (Luzerna - T1 and Ipira - T2) and one in Descanso, in the far West of the state (T3). The main focus was the mineralogical composition of the clay fraction, identified by X-ray diffractometry (XRD), and its relations with the soil chemical properties. The morphological, chemical, and mineralogical properties of the soils of the toposequences differed from each other. In most soils, the position of the most intense XRD reflections indicated predominance of kaolinite (K) however, for being broad and asymmetric, a participation of interstratified kaolinite-smectite (K-S) was assumed. Soils of T2 and T3, located in regions with higher temperatures, lower water surplus, and lower altitude than those of T1, were more fertile, mostly redder, and contained higher proportions of smectites (S) and interstratified K-S mineral, accounting for a higher activity of the clay fraction of most soils. The T1 soils were generally less fertile, with lower clay activity and, aside from kaolinite, contained smectites with interlayered hydroxy-Al polymers (HIS). The low estimated smectite contents of the most fertile soils of all toposequences disagree with the high values of cation exchange capacity (CEC) and clay activity related to pure kaolinite soils. The broad and asymmetric reflections of most of the supposed kaolinites identified as dominant minerals indicate the presence of K-S interlayers, most likely contributing to raise the CEC of the soils.

title: Evidence of genetic differentiation and karyotype evolution of the sedges Cyperus ligularis L. and C. odoratus L. (Cyperaceae)

description: ABSTRACT The taxonomy of Cyperaceae is complex, with genera like Cyperus harboring species complexes. We analyzed the genetic similarity between Cyperus ligularis L. and C. odoratus L. based on DNA fingerprinting and cytogenetics. Significative genetic differentiation (G ST = 0.363) and low gene flow (N m = 0.877) indicated a clear genetic distinction between the two species. Moreover, the clustering analysis showed two distinct genetic groups, suggesting a lack of evidence for hybridization. The phenogram revealed two different lineages, and although all individuals of C. odoratus were collected from plots close to each other, they possessed greater genetic diversity than that observed among individuals of C. ligularis, which were sampled over a wider geographic range. Variation in chromosome number within the two species exhibited the opposite pattern, indicating greater karyotype stability in C. odoratus with 2n = 72 and 2n = 76, while the diploid number for C. ligularis varied from 2n = 66 to 88. The lower genetic variation in C. ligularis may be a result of the founder effect associated with seed dispersion and clonal reproduction. Field observations and analysis of reproductive biology should enrich the understanding of the genetic structure of the investigated populations and their role in successional processes.

title: Residual stresses in clad pressure vessel steel measured by contour method

description: Data from contour method cut surfaces of low alloy steel plates clad in stainless steel. Two plates, each measuring 300 mm (length) x 200 mm (width) x 20 mm (thickness), were extracted from the outer cylindrical structure of a nuclear steam generator. The material was forged 18MND5 (French designation equivalent to A 508 Gr.3 Cl. 1). Stainless steel beads were then deposited, by submerged arc strip cladding, on the plates. One plate was clad in a single layer of AISI 309L, the second one was clad with a double layer, 309L followed by 308L. The datasets are in the form of lists of x, y, z coordinates, with one point per line, whitespace delimited in millimetres. Each cut has four files associated to it, two for each cut surface. For each surface, there is an outline file identifying the cut surface periphery and a points file containing the points lying on the surface. Two .mat files have also been uploaded, with the results from the analyses on the single and double layer clad plates. These measurements are part of a broader experimental investigation to better understand the role of residual stresses in underclad cracking. The contour method was used to characterise residual stresses in conjunction with neutron diffraction measurements. The details of the experimental procedure and other information will be found in the paper “Internal stresses in a clad pressure vessel steel during post-weld heat treatment and their relevance to underclad cracking" Cattivelli et al., soon to be published.

title: Chromosome numbers and the systematics of tribe Vochysieae (Vochysiaceae)

description: ABSTRACT With five neotropical genera and ca. 220 species, Vochysieae is the largest tribe of Vochysiaceae, comprising more than 90 % of its species. Preliminary phylogenetic analyses with matK sequence data indicated that Vochysieae may be paraphyletic, separated into the clades QRC (Qualea, Ruizterania and Callisthene) and VS (Vochysia, Salvertia). Whether the genera and the infrageneric taxa are artificial is still controversial. In this study, we analyzed the distribution of chromosome numbers in mitotic or meiotic cells among 20 species belonging to the genera Callisthene, Qualea, Salvertia, and Vochysia, that are native and common in Central and Southeast Brazilian forests or savannas. Species of Callisthene and Qualea possessed 2n = 22, while species of Salvertia and Vochysia had 2n = 24 (or n = 12). These chromosome numbers corroborate the recognition of two groups, and also suggest that chromosome evolution based on numerical variation is conservative in these lineages.
