title: New national potato genotypes: yield response to different doses of 4-14-8 NPK fertilizer

description: ABSTRACT The fertilization of potato crops generally does not take into account the genotype, although genotypes may respond differently to fertilization. This study aimed to determine the yield of new potato genotypes (cultivar BRS Camila and clone CL 02-05), as well as the cultivar Ágata, submitted to four NPK 4-14-8 fertilizer doses (0, 2, 4 and 6 t ha-1) in the crop seasons of 2013/14 and 2014/15. We evaluated the total and marketable tuber yield, total and marketable tuber number, percentage of marketable tuber dry weight, average marketable tuber weight and plant growth period. The experimental design was randomized blocks in split plot scheme, with fertilizer doses allocated as main plots and genotypes as subplots, with three replications. We did not observe significant interaction for any analyzed variable. The clone CL 02-05 showed higher total and marketable tuber yield compared to the other cultivars, mainly due to its higher production of tuber number. However, we observed a high amount of tubers not suited for commercialization from the clone CL 02-05. Cultivar BRS Camila produced fewer marketable tubers than cultivar Ágata in crop season 2014/15, but without difference in marketable yield. On the other hand, plants of cultivar BRS Camila had a longer growth period of 7 days and the tubers of this cultivar accumulated higher percentage of dry weight compared to cultivar Ágata. The new tested genotypes had yield response similar to cultivar Ágata when submitted to doses of 4-14-8 NPK fertilizer. Therefore, the fertilization management of these new genotypes may be similar to that used with cultivar Ágata.

title: Initial development of lettuce in vermicompost at higher trichoderma doses

description: ABSTRACT The study aimed to evaluate the initial development, as well as, the chemical characteristics of lettuce plants grown in substrate with high concentrations of bioagent (trichoderma). A completely randomized design with four replicates was used. The treatments, applied to a substrate composed of a blend of vermicompost and commercial substrate, were established by the following doses of the commercial product ICB Nutrissolo Trichoderma: T1) 0.0; T2) 1.0; T3) 2.0; T4) 4.0; T5) 8.0 and T6) 16.0x1011 conidia kg-1 of product. After inoculation, the substrate was placed in trays, where 50 lettuce seeds were sown on each replication. Plants were thinned after emergency stabilization, maintaining ten seedlings per tray. At 28 days after sowing, the characteristics percentage and emergence speed index, leaf area, fresh and dry leaf biomass, volume, length and surface area of the root were evaluated. We also determined the chemical characteristics of the leaves. The percentage of seed germination and the emergence speed index were lower at doses higher than 4.0x1011 conidia kg-1 of the biological product. All the studied doses influenced negatively in shoot and root development of the plants. The percentage of nutrients in the leaves was higher in treatments with ICB.

title: Physical therapists in primary health care: analysis of the national register of health service providers

description: ABSTRACT This study aimed to describe the distribution of physical therapists in the Brazilian primary health care (PHC) and the ratio of inhabitants per physical therapist in PHC, according to the National Register of Health Service Providers (CNES - Cadastro Nacional de Estabelecimentos de Saúde). A descriptive cross-sectional study was conducted from CNES and Census/2010 data. In total, 6,917 physical therapists were registered in PHC, and most were located in the Southeast region (49%). Southeast and South were the regions with the best ratios of inhabitants per physical therapist in PHC (about 23,000/1). The North presented a ratio of 32,000 inhabitants/professional. 47% of the Brazilian cities have a physical therapist in PHC. Our analysis by population size indicated a higher percentage of physical therapists in PHC in small (39%) and midsize cities (34%). The best inhabitants/physical therapist ratio occurred in small cities of the Southeast (6,948/1) and the worst, in metropolises of the Midwest (371,672/1). Small cities have physical therapists only in PHC; on the other hand, most cities of larger sizes have physical therapists in all health care levels.

title: Detection and molecular characterization of Cryptosporidium spp. in captive canaries (Serinus canaria) using different diagnostic methods

description: Abstract This study used several diagnostic methods to examine the occurrence of and molecularly characterize Cryptosporidium spp. in captive canaries (Serinus canaria) in southern and southeastern Brazil. A total of 498 fecal samples were purified by centrifugal-flotation using Sheather's solution. Cryptosporidium spp. diagnosis was performed using three diagnostic methods: malachite green negative staining, nested PCR targeting the 18S rRNA gene, followed by sequencing the amplified fragments, and duplex real-time PCR targeting the 18S rRNA specific to detect Cryptosporidium galli and Cryptosporidium avian genotype III. The overall positivity for Cryptosporidium spp. (total samples positive in at least one protocol) from the microscopic analysis, nested PCR and duplex real-time PCR protocol results was 13.3% (66/498). The positivity rates were 2.0% (10/498) and 4.6% (23/498) for Cryptosporidium spp. by microscopy and nested PCR, respectively. Sequencing of 20 samples amplified by nested PCR identified C. galli (3.0%; 15/498), Cryptosporidium avian genotype I (0.8%; 4/498) and Cryptosporidium avium (0.2%; 1/498). Duplex real-time PCR revealed a positivity of 7.8% (39/498) for C. galli and 2.4% (12/498) for avian genotype III. Malachite green negative staining differed significantly from nested PCR in detecting Cryptosporidium spp. Duplex real-time PCR was more sensitive than nested PCR/sequencing for detecting gastric Cryptosporidium in canaries.

title: Digital Knowledge and its Urgencies: reflections on digital immigrants and digital natives

description: Abstract: The proposals of Don Tapscott (apud Prescott, 2008) and Prensky (2012) are discussed in the educational sphere, evidencing the emergence of a new generation of individuals associated with Information and Communication Technologies (ICTs). This study reflects on the interferences and the potentialities of ICTs, proposing a scale between the knowledge of digital natives and immigrants (Prensky, 2001), from the theoretical-methodological perspective of French semiotics (Fontanille; Zilberberg, 2001). The main educational policies in the Brazilian context in favor of digital education are also discussed, from professional development to the implementation of technologies in school. From theory to pedagogical practice, this is the path outlined in this study.

title: Programming and scheduling sugarcane harvesting fronts: model and solution methods for large-scale problems

description: Abstract: In a recent study, optimization models were proposed for programming and scheduling sugarcane harvesting fronts. This is a complex agricultural and logistic problem comprising various factors, such as raw material maturation stage, harvesting at the agricultural unit, transporting of raw material to the plant, and milling capacities of the plant. In this study, one of the optimization models previously studied was used to represent this problem using Mixed Integer Programming (MIP) of a lot sizing and scheduling model in parallel machines with sequence dependent setup times and costs. The proposed methods are based on MIP heuristics to solve this model in a real situation of a harvest season of a typical company from this sector inspired by harvest block aggregation heuristics, relax-and-fix constructive heuristics, and fix-and-optimize improvement heuristics. To compare the performance of the heuristic methods, various experiments were conducted using different combinations and variations of these methods. Three approaches were able to produce good quality solutions. One of them is described in detail and analyzed in this study, showing promising results in terms of making programming and scheduling decisions concerning sugarcane harvesting fronts.

title: The use of animal-assisted therapy: a bioethical question

description: Abstract This paper addresses ethical questions concerning animal-assisted therapy (zootherapy). While it has been documented for centuries in several cultures and is resistant to urban and technological developments, it combines multiple moral and vulnerable agents, constituting a dilemma whose fair and consensual solution calls for new perspectives, like environmental bioethics. Through analyses of scientific texts, the arguments and values intrinsic to decisions about how and when to use animals as medical resources are systematized. Using bioethics as a method, reflections are offered about the potential solutions dependent on the multidimensional communication between the players from the three pillars of sustainability - environment, society, and economy - involved in this global ethical question, focusing on conservation and sustainable production.

title: Cryopreservation of banana’s cv Grand Naine in vitro rhizomes

description: ABSTRACT The preservation of banana genetic material is usually performed through seedlings. However, most banana cultivars do not produce seed and are propagated vegetatively. Therefore, cryopreservation is a feasible technique that allows the preservation of banana genotypes indefinitely. For the success of cryopreservation protocols, the selection of cryoprotectants and pre-freezing techniques are important factor. Therefore, the objective of this study was to verify the effects of different cryoprotectants with and without 1% phloroglucinol and pre-cooling periods on the development of a protocol for cryopreservation of in vitro rhizomes ofMusa accuminata(AAA) cv Grand Naine banana. The addition of 1% phloroglucinol to the cryoprotective solutions, such as PVS2 enhanced recovery of cryopreserved banana rhizomes. In addition, pre-cooling of explants in ice for 3 hours in PVS2 + 1% of phloroglucinol allowed efficient cryopreservation of banana rhizomes, followed by successful recovery and regeneration of in vitro shoots of banana cv Grand Naine.
