Abstract: this study aimed to review the literature addressing motor physical therapy for intensive care unit adult patients. a literature search was conducted in the databases, pubmed, medline (international literature and health), lilacs (latin american and caribbean health sciences) and cochrane between 1995 and december 2008 using the keywords: physical therapy, mobilization and intensive care unit. for comparison purposes we selected randomized controlled trials and prospective studies, addressing the subject motor physical therapy for intensive care unit adult patients. pediatric and experimental studies, systematic reviews and meta-analysis were excluded. of the 121 articles identified, only 4 met the inclusion criteria. among these, three focused early motor physical therapy in patients with a range of diagnoses, showing that these patients left the bed and walked earlier, and stayed shorter both in the intensive care unit and hospital. furthermore, patients on early motor physical therapy had shorter mechanical ventilation duration. another paper compares the use of electrical stimulation associated with physical therapy in chronic obstructive pulmonary disease patients, showing increased muscle strength and shorter time for these patients bed to chair transference as compared with those only receiving physiotherapy. the risks of immobilization in mechanically ventilated critically ill patients are not fully understood. however, it is clear that the survivors show impaired quality of life due to persistent weakness and fatigue. early mobilization is a new area, with little evidence so far. however, recent studies have confirmed that mechanically ventilated patients mobilization is safe and feasible, reducing both the intensive care unit and hospital stay. however, more studies are warranted to identify the exercise type, duration, intensity and impact for of early motor therapy in specific groups of patients.

Abstract: The use of plants on wastewater treatment represents a low cost energy technology, which seems to be a good alternative to conventional systems. Based on this trend, narrowleaf cattail (Typha angustifolia L.) plants on a root zone wastewater treatment were used. Plants submitted to wastewater showed 48.5% of their inflorescenses with deformations like double, triple and quadruple types. No differences on leaf nutrient contents of both deformed and normal inflorescenses were observed. This deformation was attributed to wastewater application, since no deformed plants has been found on natural environments. KEY-WORDS: Plant tissue analysis; wastewater treatment; root zone. A utiliza o de plantas no tratamento de esgoto representa uma tecnologia de baixos custos energéticos, que está se revelando como uma boa alternativa aos sistemas convencionais. Em vista dessa tendência, empregaram-se plantas de taboa (Typha angustifolia L.) num sistema de tratamento de esgotos do tipo zona de raízes. As plantas submetidas ao esgoto sanitário apresentaram 48,5% de inflorescências com deforma es dos tipos dupla, tripla ou quádrupla. N o se verificaram diferen as nos teores de nutrientes nas folhas das plantas, com e sem deforma o na inflorescência. Atribuiu-se a ocorrência de deforma es ao efeito da aplica o do esgoto, uma vez que n o se observaram plantas com inflorescências deformadas em ambiente natural. PALAVRAS-CHAVE: Análise foliar; tratamento de esgotos; zona.

Abstract: software process improvement and software process assessment have received special attention since the 1980s. some models have been created, but these models rest on a normative approach, where the decision-maker's participation in a software organization is limited to understanding which process is more relevant to each organization. the proposal of this work is to present the mcda-c as a constructivist methodology for software process improvement and assessment. the methodology makes it possible to visualize the criteria that must be taken into account according to the decision-makers' values in the process improvement actions, making it possible to rank actions in the light of specific organizational needs. this process helped the manager of the company studied to focus on and prioritize process improvement actions. this paper offers an empirical understanding of the application of performance evaluation to software process improvement and identifies complementary tools to the normative models presented today.

Abstract: guanandi (calophyllum brasiliense) clonal propagation through minicuttings. the goal of this research was to determine guanandi (calophyllum brasiliense) clonal propagation efficiency of hisforesty species through minicutting technique. a miniclonal garden was first established in sand beds, where new sprouts were produced for their use as minicuttings. two experiments were performed in order to refine propagation protocols. the first experiment assessed the performance of 2 different types of minicuttings (apical and intermediate within the sprout) exposed to three iba dosages (0, 2000, 4000, and 8000 mg.l-1). in the second experiment, minicuttings were sown in 3 different substrates (vermiculite, burned rice husk and decomposed pine-bark). rooting percentages did not vary among treatments in the first experiment. in the second experiment, a greenhouse-permanency time reduction, under vermiculite substrate condition, was registered. as a general conclusion, the minicutting technique was an efficient strategy for guanandi clonal propagation.
