Organic fertilization with poultry litter and sugarcane juice quality / Adubação orgânica com cama de aviário e qualidade do caldo da cana-de-açúcar

The ripening of sugarcane is influenced by weather conditions, crop variety and practice. Harvesting ripe sugarcane reduces transportation costs and increases industrial efficiency and alcoholic fermentation. The aim of this study was to evaluate the influence of organic fertilization with poultry litter on sugarcane ripening and juice quality. We used first and second regrowth of sugarcane variety RB867515 grown in medium-textured soil. The study was conducted in the city of Viçosa, state of Minas Gerais (MG), Brazil. The experiment was a randomized complete block design with four replicates. The treatments consisted of three doses of poultry litter (7.0; 10.0 and 13.0 t of dry matter ha/yr), chemical fertilization (180 kg N + 225 kg K ha/yr) and a control (no chemical or organic fertilization). In both years, sugarcane was harvested in early August. There was no influence of poultry litter fertilization on sugarcane ripening and juice quality. The average contents of soluble solids, sucrose in juice, stalk fiber and juice purity were respectively 22%; 19% and 88%.

The influence of civic mindedness, trustworthiness, usefulness, and ease of use on the use of government websites

Inclinación cívica y las percepciones de confiabilidad, utilidad y facilidad de uso parecen explicar gran parte del uso efectivo de los sitios web. En este artículo se analiza el grado en que estos factores influyen en el uso de los sitios web del gobierno sobre la base de un estudio con 210 ciudadanos que estaban haciendo su registro electoral biométrico en João Pessoa - una grande ciudad en Brasil. Con la ayuda de modelos de regresión (mínimos cuadrados ordinarios y por cuantiles), se encontró que existe influencia mixta de esos factores en el uso de los sitios web gubernamentales. En promedio, la utilidad percibida y la facilidad de uso percibida tuvieron una influencia significativa; pero para los bajos niveles de utilización, solamente la utilidad percibida tuvo una influencia, mientras que la facilidad de uso percibida tuvo una influencia para niveles moderados y altos de uso. En términos de confiabilidad, sólo la dimensión de la confianza en el gobierno tuvo una influencia para todos los niveles de uso. En términos de civismo, sólo la dimensión sobre participación cívica tuvo una influencia, a excepción de niveles moderados de uso. Nuestros resultados refuerzan que el desarrollo de sitios web del gobierno debe centrarse en los perfiles individuales de los ciudadanos y en los niveles de uso, es decir, el foco debe estar dirigido hacia el lado de la demanda (usuarios), además de simplemente hacer frente a los requerimientos legales y la prestación de servicios por el proveedor (gobierno).Civic mindedness and the perceptions of trustworthiness, usefulness, and ease of use seem to explain much of the effective use of websites. This article discusses the extent to which such factors influence the use of government websites based on a study with 210 citizens who were doing their biometric electoral registration in João Pessoa – a major city in Brazil. With the help of ordinary least squares and quantile regression models, we found that there is mixed influence of those factors on the use of government websites. On average, perceived usefulness and perceived ease of use had a significant influence; but for low levels of use, only perceived usefulness had an influence, whereas perceived ease of use had an influence for moderate and high levels of use. In terms of trustworthiness, only the dimension about trust in government had an influence for all levels of use. In terms of civic mindedness, only the dimension about civic engagement had an influence, except for moderate levels of use. Our results reinforce that the development of government websites should focus on the citizens’ individual profiles and levels of use, that is, focus should be directed to the demand side (users) besides merely addressing the legal requirements and the provision of services by the supplier (government).Inclinação cívica e as percepções de confiabilidade, utilidade e facilidade de uso parecem explicar o uso efetivo de sítios web.

Nitrogen fertilization in sugarcane nurseries / Adubação nitrogenada em viveiros de cana-de-açúcar

The production of healthy sugarcane seedlings and varieties with high yield potential is the most costly aspect in setting up a sugarcane field. This study evaluated the effect of nitrogen fertilization at 0, 40, 80, 120 and 160 kg N ha-1 on plant nutritional status and seedling yield of two varieties of sugarcane: RB835486 and RB867515. The study was conducted in an experimental design of randomized blocks with four replications in a medium textured soil in the city of Mercês, located in the Mata Mineira region, from October 2015 to March 2016. The soil received liming and gypsum at a dose of 5.0 t of dolomitic limestone and 1.5 t of gypsum. The soil was then plowed, harrowed and subsoiled. We applied 100 kg P (229 kg P2O5) and 200 kg potassium to the bottom of the planting furrow. Nitrogen fertilization did not affect plant nutritional status and seedling yield. The plants were well nourished and the average yield was 65 t of seedlings per hectare.The production of healthy sugarcane seedlings and varieties with high yield potential is the most costly aspect in setting up a sugarcane field.

Interdisciplinary approach to treat dyskeratosis congenita associated with severe aplastic anemia: A case report

This paper reports on a 4-year-old male who had dyskeratosis congenita and who acquired severe aplastic anemia. The patient developed hyperpigmentation of the face, neck and chest region, arms, shoulders and legs. In addition, he had dry skin, deformed fingernails and toenails, sparse hair and eyebrows and hyperkeratosis of the dorsum of the hands and feet. Laboratory and histological analysis revealed severe pancytopenia and dyserythropoiesis of red blood cells, hypocellularity of white blood cells and decreased megakaryocytes with dysplasia. The intraoral examination identified bleeding gums; petechiae of the palate, tongue and cheek mucosa; and an atrophic, smooth and shining dorsal surface of the tongue. There were deep carious lesions in the deciduous mandibular molars and maxillary anterior teeth; as well as mobility of mandibular left canine, which had bone loss. The treatment for oral lesions included diet changes, improved oral hygiene, and extraction of the deciduous teeth destroyed by caries
