Influence of spray mixture volume and flight height on herbicide deposition in aerial applications on pastures

The objective of the present study was to analyze the influence of spray mixture volume and flight height on herbicide deposition in aerial applications on pastures. The experimental plots were arranged in a pasture area in the district of Porto Esperidião (Mato Grosso, Brazil). In all of the treatments, the applications contained the herbicides aminopyralid and fluroxypyr (Dominum) at the dose of 2.5 L c.p. ha-1, including the adjuvant mineral oil (Joint Oil) at the dose of 1.0 L and a tracer to determine the deposition by high-performance liquid chromatography (HPLC) (rhodamine at a concentration of 0.6%). The experiment consisted of nine treatments that comprised the combinations of three spray volumes (20, 30 and 50 L ha-1) and three flight heights (10, 30 and 40 m). The results showed that, on average, there was a tendency for larger deposits for the smallest flight heights, with a significant difference between the heights of 10 and 40 m. There was no significant difference among the deposits obtained with the different spray mixture volumes.

Initial height of pasture deferred and utilized in winter and tillering dynamics of signal grass during the following spring

Tillering dynamics during regrowth in the spring (September to December 2009) on signal grass (Brachiaria decumbens cv. Basilisk) pastures deferred in the beginning of April 2009 is evaluated. Four pasture heights were evaluated at the beginning of deferment (10, 20, 30 and 40 cm). The experimental design consisted of completely randomized blocks with two replications. Rise in pasture height at the beginning of deferment decreased the appearance rate, increased the mortality rate and reduced the survival rate, the balance between appearance and mortality and the stability index of the tiller population at the beginning of the spring. Pastures deferred at initial height of 30 and 40 cm presented relatively stable tiller appearance rate between the beginning and end of spring. However, these pastures presented greater mortality rate, lower survival rate, lower balance between appearance and mortality and lower stability index of the tiller population at the beginning of spring when compared to rates at the end of spring. Pastures managed with shorter initial heights (10 and 20 cm) provided more tissue renewal in the subsequent growth season after their utilization in the winter.

Evolução antropométrica de crianças hospitalizadas com diarréia persistente e desnutrição grave, submetidas a suporte nutricional

In order to estimate the nutritional rehabilitation (NR) during admission of malnourished children with persistent diarrhea (PD) receiving standardized nutritional support (NS), we prospectively evaluated the weight, height, head circumference and arm measurements (AM) of 20 children, 19 below 1 year, admitted to the ward with weigh/age -2.89 to -5.21 standard deviation. Four infants comprised the death group (DG) and 16 survived (SG). The SG was separated, according to initial weight behavior, into weight gain (WG) or weight loss (WL). Compared to SG at admission, DG only had lower AM and more metabolic-infectious alterations (p<05). The survivors presented NR but this was evident for WL only when considering the minimum weight. DG received less calories than SG and weight loss during the pre-death period was higher than for WL (p<05). It was concluded that very altered AM, severe metabolic-infectious insults, low caloric input and high weight loss velocity are associated to bad prognosis; severely malnourished infants with PD began NR during hospitalization while receiving adequate NS, but minimum weight must be considered for this evaluation; AM must be obtained at admission, due to its prognostic value, and adequate NS as well as anthropometric follow-up during the hospital stay are essential.

Urinary flow in children: correlation with age, body height and body surface area

Peak flow rate data (Qmax) are important for diagnosis of lower urinary tract obstruction. However, the lack of uroflowmetry studies in children, makes their interpretation difficult. With this aim, we studied 167 boys classified in four groups according to their age (G1: n = 48, 6-7 years; G2: n = 43, 8-9 years; G3: n = 37, 10-11 years; G4: n = 39, 12-14 years). We studied in all children, weight, height, body surface area, peak flow rate (Qmax) and the correspondant urinary volume (Vol). Means and standard deviations of Qmax (ml/sec) were: 15 +/- 5 (G1), 15 +/- 5 (G2), 17 +/- 5 (G3) and 22 +/- 7 (G4) respectively. Corresponding urinary volumes (Vol) (mean standard deviation-in ml) were: G1 = 123 +/- 75; G2 = 122 +/- 79; G3 = 158 +/- 96 and G4 = 162 +/- 101. We found a significant correlation (p < 0,01) between Qmax and Vol in groups G2, G3 and G4; and between Qmax and height in groups G1 and G4. The authors demonstrated a positive correlation between maximum flow and voided volume, and an increase of Qmax with age.

Assimetria no controle postural em idosos caidores e não caidores neurologicamente sadios e com doenã de Parkinson em diferentes posições estáticas

Individuals with Parkinson's disease (PD) seem to present asymmetric postural control, and the commitment to postural control that is a big factor of falls in this population. However, the asymmetry in the postural control of fallers and non fallers with PD and neurologically healthy elderly is not too much studied. The objective of the study is to analyze the asymmetry in postural control in different static positions of elderly patients with PD and healthy elderly fallers and non fallers. The study included 70 older adults with PD and 70 neurologically healthy (CG). The groups were matched for age, gender, height, weight and cognitive condition. It was evaluated the clinical, cognitive status and incidence of falls among its participants through weekly prospective follow-up of 4 months. Then, for each group, CG and PD, it was selected 12 elderly fallers and 12 elderly non fallers to evaluate postural control. Participants were evaluated through two force platforms in conditions of bipedal support, unipedal and tandem position. It was realized 3 attempts of 30s for each condition. For unipedal and tandem condition it was made 3 attempts for each lower limb. The parameters of interest of the center of pressure (CoP), were analyzed for each condition and compared by MANOVAs with factor group, fall and asymmetry. Post hoc Tukey tests were used to determine the relationships between them. The results show that CG individuals showed greater velocity and CoP area in relation to PD. It was verified that at the control group that non fallers individuals (CGN) had more displacement and RMS in the average lateral direction in the dominant limb when compared to the less affected limb of non fallers with PD (PDN). Faller individuals in the control group (CGF) had larger area in the non dominant limb when compared to the most affected leg of fallers individuals with PD (PDF). Still, the PDF individuals had higher RMS in anteroposterior feeling....
