25. Identifying forest ecosystem regions for agricultural use and conservation
ABSTRACT Balancing agricultural needs with the need to protect biodiverse environments presents a challenge to forestry management. An imbalance in resource production and ecosystem regulation often leads to degradation or deforestation such as when excessive cultivation damages forest biodiversity. Lack of information on geospatial biodiversity may hamper f

26. Impacto de la regla de decisión en el modelado de la difusión de innovaciones
Abstract In this, paper we analyze the impact of the decision rule to represent the behavior of individuals in the diffusion curve predicted by models of innovation diffusion at the individual level. We use an agent-based model, in which diffusion takes place in a small-world network, and analyze the phenomenon using 4 different decision rules: (1) threshold

27. Effects of REM sleep restriction during pregnancy on rodent maternal behavior
Objective: To evaluate the effects of sleep restriction during pregnancy on maternal care and maternal aggression in a rodent model. Methods: Twenty-three female Wistar rats were assigned to one of two groups: control (n=12) or sleep restriction (n=11) during the entire pregnancy. At the fifth postpartum day, the animals were subjected to the resident-intr

28. Consumer Complaints and Company Market Value
Consumer complaints affect company market value and common sense suggests that a negative impact is expected. However, do complaints always negatively impact company market value? We hypothesize in this study that complaints may have a non-linear effect on market value. Positive (e.g. avoiding high costs to solve complaints) and negative (e.g. speedy and int

29. Effect of disparity on the perception of motion-defined contours
We present three experiments that explored the effect of binocular disparity on the perception of contours defined by motion in a Spatiotemporal Boundary Formation. Depending on the disparity, the stimulus is perceived as an object that moves behind a holed surface (occluded configuration) or as a luminous transparency that moves over a surface that contains

30. Acute inflammatory response to transgastric natural orifice transluminal endoscopic surgery peritoneoscopy: An experimental study in swine
OBJECTIVE: To investigate the impact of transgastric peritoneal access on plasma biomarkers of acute inflammatory response in comparison to laparoscopy. METHODS: This was a prospective and comparative study in a porcine model. Transgastric peritoneal access performed by natural orifice transluminal endoscopic surgery was compared with laparoscopy. Laparot

31. The implementation of the Neuroid in the Gate Control System leads to new ideas about pain processing
INTRODUCTION: Several theories have been proposed to elucidate the mechanisms related with pain perception, among which, the Gate Control Theory (GCT) provides one of the most explicit explanations. This theory, as elegantly conceived, is unable to explain how the Frequency-Intensity (F-I) curves exhibited by Aβ- and C-fibres influence pain processing. In t

32. Non-flat audiograms in sensorineural hearing loss and speech perception
OBJECTIVE: The audibility thresholds for the sound frequency of 137 upward- and downward-sloping audiograms showing sensorineural hearing loss were selected and analyzed in conjunction with speech recognition thresholds obtained from individuals seen at a public otolaryngology clinic to determine which frequencies in slope audiograms best represent speech r

33. An improved experimental model for peripheral neuropathy in rats
A modification of the Bennett and Xie chronic constriction injury model of peripheral painful neuropathy was developed in rats. Under tribromoethanol anesthesia, a single ligature with 100% cotton glace thread was placed around the right sciatic nerve proximal to its trifurcation. The change in the hind paw reflex threshold after mechanical stimulation obser

34. Retrograde Renal Cooling to Minimize Ischemia
Objective:During partial nephrectomy, renal hypothermia has been shown to decrease ischemia induced renal damage which occurs from renal hilar clamping. In this study we investigate the infusion rate required to safely cool the entire renal unit in a porcine model using retrograde irrigation of iced saline via dual-lumen ureteral catheter.Materials and Metho

35. Neurophysiological correlates of color vision: a model
The tree-receptor theory of human color vision accounts for color matching. A bottom-up, non-linear model combining cone signals in six types of cone-opponent cells in the lateral geniculate nucleus (LGN) of primates describes the phenomenological dimensions hue, color strength, and lightness/brightness. Hue shifts with light intensity (the Bezold-Brücke ph

36. Modelo de tomada de decisões em disciplinas vinculadas às ciências da enfermagem: revisando as bases conceituais para formação de novos perfis profissionais. / Decision-making model in technical subjects of nursing: Revising the conceptual basis for the building of new professional profiles.
This research has as an object of study the syllabus of courses related to Nursing Sciences which are part of the curriculum of undergraduate courses and aims to understand how the process of decision making has been aired in these subjects with a focus on the training of nurses. The research is justified by the fact that there is a lack of information about
