Abstract: the errors present in the tasks of a subject builder of knowledge are important because, tthey are observable and promote the process of balancing. for the researcher, clinician or teacher, the observation of constructivist errors can guarantee a minimum objectivity in the process of diagnosis and intervention. our intention in this review of theoretical work is to characterize the error inherent in the activity as part of the subject construction that, when placed to resolve a problem, taking advantage of this error is to promote the opening of new possibilities. we try to update the characterization of errors as part of the learning process and highlight the logic of children. we criticiz the positions that consider the error as evidence of disability and difficulties in solving tasks.

Abstract: Meningomyelocele is a congenital defect involving the central nervous system which is one of the most common among those compatible with life. Children affected by this condition present neurological, orthopedic, renal and urogenital complications, needing lifelong healthcare provisions. The aim of this study was to analyze the reality experienced by children and adolescents with meningomyelocele and their families in the city of Belo Horizonte and its metropolitan area, Brazil. A descriptive and exploratory study was conducted via three home visits and a scripted interview with 16 children and adolescents with meningomyelocele and their families. It was observed that mean age of children and adolescents was 12 years old, most of them did not walk (n = 10), and depended on wheel chairs and parental care. Mothers represented the main caregivers and most (n = 12) had to leave their formal work outside of the home, compromising family income. It concluded that the families had socioeconomic levels aggravated by difficulties in purchasing materials needed for their children’s care. Some social challenges included barriers to education and the acquisition of medications and materials, demonstrating the need for planning public policies aimed at integrating different health services.

Abstract: the objective of this work was to simulate maize leaf development in climate change scenarios at santa maria, rs, brazil, considering symmetric and asymmetric increases in air temperature. the model of wang & engel for leaf appearance rate (lar), with genotype-specific coefficients for the maize variety brs miss?es, was used to simulate tip and expanded leaf accumulated number from emergence to flag leaf appearance and expansion, for nine emergence dates from august 15 to april 15. lar model was run for each emergence date in 100-year climate scenarios: current climate, and +1, +2, +3, +4 and +5°c increase in mean air temperature, with symmetric and asymmetric increase in daily minimum and maximum air temperature. maize crop failure due to frost decreased in elevated temperature scenarios, in the very early and very late emergence dates, indicating a lengthening in the maize growing season in warmer climates. the leaf development period in maize was shorter in elevated temperature scenarios, with greater shortening in asymmetric temperature increases, indicating that warmer nights accelerate vegetative development in maize.

Abstract: the objective of this work was to compare phyllochron and leaf area on individual stalks of selected sugarcane (saccharum officinarum) clones grown in a subtropical environment. a two-year field experiment was carried out in santa maria, rs, brazil, during the 2007/2008 and 2008/2009 growing seasons. three sugarcane clones were used: iac 822045 (early), sp 711406 (median) and cb 4176 (late), in a complete randomized block design, with four replications. expanded leaf and total leaf (tips) number were determined, and expanded leaf area was measured. the phyllochron (oc day leaf-1) based on expanded and tip leaf number was estimated, using 10oc as base temperature. allometric relationships between individual area and number of expanded leaves were fitted. phyllochron was analysed as a four-factor experiment: clone, growing season, phyllochron phase, and phyllochron type. the early clone had the greatest potential for growing in a subtropical climate because of higher leaf output and leaf area.

Abstract: the objective of this study was to simulate the development of maize in elevated temperature scenarios at santa maria, rs, brazil. the developmental cycle of maize was simulated with the wang and engel (we) model with genotype-dependent coefficients for the cultivar brs miss?es. the developmental cycle was divided into vegetative phase (from emergence to silking), and reproductive phase (from silking to physiological maturity). twelve sowing dates throughout the year were considered, resulting in emergences on the day 15 of each month all year round. climate scenarios used were synthetic time series of 100 years of current climate and with increase in mean air temperature of +1, +2, +3, +4, and +5, with symmetric and asymmetric increases in daily minimum and maximum temperatures. as temperature increased, the number of years in which crop was killed by frost decreased, indicating that if global warming will confirm, the growing season for maize grown in subtropical environment will be longer by the end of this century. maize vegetative and reproductive development was delayed or hastened depending upon the emergence time of the year, and if the increase in air temperature is symmetric or asymmetric, indicating complex genotype x environment interactions and high vulnerability of maize development to climate change.

Abstract: Phytosterols are plant sterols structurally similar to cholesterol. The most common phytosterols are -sitosterol, campesterol and stigmasterol. They are present in many foods but mainly in nuts and vegetable oils. They compete with cholesterol absorption decreasing the cardiovascular risk. Recent studies have associated the intake of 0.63-3g/day of phytosterols with lowering serum cholesterol and LDL-cholesterol levels. The same decrease has been observed in apolipoprotein B. These results suggest that dietary phytosterols are useful for protection against cardiovascular disease. Because of this they have been incorporated in relatively high quantities into spreads and margarines. However, negative effects have also been reported. Among them, a significant decrease in the absorption of several lypophilic antioxidant compounds such as carotenoids and tocopherols, which may counterbalance the protective cardiovascular effect of phytosterols. In this paper the results of several selected studies relating phytosterol consumption and plasma levels of lipids, lipoproteins and antioxidants are reviewed. More studies are needed to establish if it is necessary to supplement with such antioxidant compounds the diet of people consuming phytosterols for therapeutical purposes. Los fitosteroles son esteroles de plantas con una estructura similar a la del colesterol. Los fitosteroles más frecuentes son: -sitosterol, campesterol y estigmasterol. Están ampliamente distribuidos en los alimentos, siendo las nueces y aceites vegetales fuentes importantes de estas sustancias. Los fitosteroles compiten en el organismo en la absorción del colesterol por lo que se han propuesto como protectores del riesgo cardiovascular. Consumos diarios de 0,63-3g/día de fitosteroles parecen disminuir tanto el colesterol plasmático como los niveles de LDL-colesterol, conjuntamente con los niveles de apolipoproteína B. Con el propósito de aprovechar dichas acciones, se han incluido en distintos productos, como margarinas y untables. Sin embargo, no todo son beneficios y su consumo también produce efectos negativos. Así, disminuyen significativamente la absorción de ciertos compuestos lipofílicos antioxidantes, como carotenoides y tocoferoles, implicados a su vez en la protección cardiovascular. En esta minirrevisión se comentan los resultados de algunos estudios que relacionan consumo de fitosteroles y concentración en plasma de lípidos, lipoproteínas y algunos antioxidantes. Se precisan estudios que diluciden si es necesario incrementar el consumo de tales compuestos antioxidantes en pobla

Abstract: Lipases belong to the group of hydrolases that catalyze the hydrolysis of triacylglycerol lipids to free fatty acids and glycerol. They have significant potential biotechnological applications in catalyzing organic synthesis reactions in non-aqueous solvents using simplified procedures resulting in conversions of high yields. Lipase production has conventionally been performed by submerged fermentation; however, solid-state fermentation processes have been prominent when residues are used as substrates because they serve as low-cost nutrient sources. Microbial lipases can be used as additives in foods to modify and enhance organoleptic properties, as well as in detergents to hydrolyse fats in the treatment of oily effluents, and also have value for pharmaceutical, cosmetic, agrochemical, and oil chemical industries. More recently, they are used in transesterification reactions to convert plant seed oils into biodiesel. The objective of this work was to review the published literature on the production, properties and applications of microbial lipases, and its biotechnological role in producing biodiesel.

Abstract: O objetivo deste trabalho foi analisar o comportamento de cultivares de feij o quanto aos testes da capacidade de absor o da água pelos gr os e do tempo de cozimento, bem como avaliar correla es entre essas características visando à identifica o precoce de linhagens de fácil cozimento. Foi adotado o delineamento experimental inteiramente casualizado, arranjado em fatorial 2 x 9, com três repeti es. As cultivares utilizadas foram TPS Nobre e Pérola e os gr os foram imersos em água destilada durante 2 a 18 horas. Os resultados obtidos evidenciaram que a capacidade de absor o da água pelos gr os aumentou com o tempo em que permaneceram embebidos, até atingir o máximo de hidrata o: 13h7min e 13h12min para as cultivares TPS Nobre e Pérola, respectivamente. O tempo de cozimento diminuiu à medida que os gr os permaneceram imersos até 12h49min, para as duas cultivares. A capacidade de absor o da água pelos gr os e o tempo de cozimento apresentaram correla o negativa e significativa.
