| ABSTRACT The Federal University of Technology - Paraná (UTFPR), Campus Curitiba, has a Grid-Connected Photovoltaic System (GCPVS) of 2.1 kWp in the Green Office (GO), which has been in operation since December 2011, and until September 2017 generated little more than 13.64 MWh and a GCPVS of 10.2 kWp, in operation since February 2016. The photovoltaic panel of the 2.1 kWp system was set up following the inclination of the roof of the building, which does not give its maximum performance. On the other hand, the panel of the 10.2 kWp system in Neoville was installed in optimum conditions, that is, oriented to the north and with slope equal to the latitude of Curitiba and, up tol September 2017 generated more than 20.65 MWh. This paper presents the monitoring... |

| Instrumental neutron activation analysis (INAA) is a measurement technique of high metrological level for the determination of chemical elements. In the context of BIOTA/FAPESP Program, leaves of trees have been evaluated by INAA for biomonitoring purposes of the Atlantic Forest. To assure the comparability of results in environmental studies, a leaf sample of Marlierea tomentosa (Myrtaceae family) showing the lowest concentrations of chemical elements was selected for the evaluation of analytical quality of the determination under unfavorable conditions. Nevertheless, the homogeneity of chemical concentrations of sample at the 95% of confidence level has been achieved and INAA has presented repeatability of 2% for the determination of Br, Co, Cs, Fe, K,... |

| Method validation is the process used to confirm that the analytical procedures employed for a specific test is able to produce reliable and replicable results. An analytical method should be conducted in order to demonstrate that it is suitable for its intended use [1]. The aim of this present work is to demonstrate and evaluate the suitability of method validation. The analytical validation discussed herein was conducted by prescribed protocol, using 3 different batches of measles's vaccine diluents. All of the stipulated validation parameters: linearity, repeatability, reproducibility (intermediate precision) and accuracy were met. Additionally, this study demonstrated the method's capability for the determining endotoxin levels in measles's vaccine... |

| The genus Calea belongs to the tribe Heliantheae and presents about 125 species. Calea serrata, popularly known as erva-de-cobra, chá-amargo and quebra-tudo, is an endemic species found in southern Brazil and is used in traditional medicine to treat ulcers and livers problems. The present work aimed to study the pharmacobotanical characters of leaves and stems of C. serrata for quality control purposes. The plant material was processed according to standard methods of light and scanning electron microscopy. Glandular capitate-stalked and capitate-sessile, uniseriate multicellular non-glandular trichome with tapered apical cell, conical non-glandular trichome, isobilateral mesophyll, secretory ducts near the endoderm and circular shape with six ribs in the... |

| In order to achieve adventitious shoot regeneration from young tissues of Racosperma mangium, several combinations of growth regulators were tested. Kinetin (KIN) and a -naphthalenacetic acid (NAA), thidiazuron (TDZ) and NAA or indole-3-butyric acid (IBA), 4-CPPU and 2,4-dichlorophenoxyacetic acid (2,4-D) were added to basic medium composed of MS salts, MS vitamins and 3% sucrose. Sections of hypocotyls and cotyledons of young seedlings were cultivated on these media. Calli developed on different media and, after two to three months, some of them regenerated organized structures. Histological studies revealed hypertrophy and hyperplasy of medular and cortical parenchyma cells of hypocotyl and cotyledon parenchyma. Formation of meristematic cells and... |

| A comparative anatomical analysis of somatic embryogenesis in two soybean (Glycine max (L.) Merrill) genotypes was carried out. The somatic embryos were originated from cotyledonary explants obtained from immature zygotic embryos. The medium used for somatic embryogenesis induction was Murashige and Skoog, 1962, salts and Gamborg et al., 1968, vitamins (MSB) supplemented with 0.8 mg.L-1 of 2,4-D for genotype PI 123439 and 40 mg.L-1 of 2,4-D for Williams 82. Globular structures, constituted by meristematic cells, originated from subepidermal cell divisions of the cotyledonary mesophyll. In PI 123439, the globular structures presented tracheary differentiation among meristematic cells and they could follow distinct morphogenetic process depending on their... |

| This work dealt with the anatomy of the underground system in Vernonia grandiflora Less. and V. brevifolia Less. (Vernonieae; Asteraceae), two perennial geophytes, to elucidate their ability to sprout in the Brazilian Cerrado conditions. V. grandiflora, a subshrubby species, possessed a thickened underground system constituted by a xylopodium and many tuberous roots. The xylopodium had stem and root structure and its buds were axillary or originated from the cortical parenchyma proliferation. The tuberous roots produced by this organ were adventitious and accumulated inulin-type fructans mainly in the cortical parenchyma. The thickened underground system of V. brevifolia, an herbaceous species, was a tuberous primary root whose buds originated from the... |

| The Pato Branco river basin, which supplies water to Pato Branco city (70,000 inhabitants) in southwestern Paraná State, was monitored during two hydrological cycles, totaling 22 campaigns at two monitoring stations on the Conrado river: the Conrado station upstream (RC01) and the Conrado station downstream (RC02). The main characteristics of the basin here: area - 29.69 km², length - 9,300 m, height difference - 170 m, declivity - 18.62 m km-1, and concentration time - 102 min. Physico-chemical variables were analyzed, using samples collected after a minimum three-day period without rain. The data set comprising seven variables yielded the following averages respectively for monitoring stations RC01 and RC02: variables that characterized the organic... |
