Background Treeline ecotones of Mediterranean ecoregions have been affected by the increasing intensity and severity of droughts. Even though the effect of droughts on forest dynamics has been widely documented, knowledge is relatively scarce of how extreme climate episodes affect the hydraulic structure and, therefore, the phys-iology of woody plants. The Mediterranean Andes have experienced an uninterrupted period of drought since 2010, including an extremely dry year in 2019 with approximately 80% rainfall deficit. Here, we investigated shifts in wood anatomical and physiological traits of Kageneckia angustifolia, an endemic treeline species, in response to this drought *** We evaluated the xylem plasticity of three K. angustifolia populations across their natural distribution(31–35° SL) based on anatomical(vessel structure and distribution) and physiological(intrinsic water-use efficiency) variables in the tree rings. We focused on the period 2000–2020 that corresponds to before the megadrought(2000–2007),(ii) megadrought(2008–2018) and(iii) hyperdrought(2019–2020). The variables were annualized and analyzed by linear mixed-effects *** Our results provide insights to the anatomical and physiological mechanisms underlying the resilience of treeline forests to persistent droughts in central Chile. We found that the extreme drought in 2019–2020 triggered shifts in vessel size and frequency that increased hydraulic safety. These significant shifts in vessel traits occurred in parallel with a decrease in pit aperture area and an increase in water-use efficiency, further increasing the resilience of K. angustifolia to extreme drought *** Our results revealed coordinated shifts in vessel size and frequency and water-use efficiency in response to the megadrought, thereby reducing vulnerability to hydraulic failure. The apparent resilience of K. angustifolia to extreme droughts suggests that this adaptation to drought stress may incre

Entwining Psychology and Visual Arts： A Classroom Experience

引用

Psychology Research 2012年第2期2卷 89-98页

作者： Sara Bahia Jos6 Pedro trindade University of Lisbon Lisbon Portugal Externato de Penafirme Torres Vedras Portugal

The purpose of this paper is to show how activating perception, imagery and creativity facilitate the mastery of specific skills of visual arts education. Specifically, the study aimed at answering two questions: How can teachers enhance visual and creative expression; and What criteria should be used to evaluate specific learning of visual arts skills Based on a literature review on visual language two specific exercises were devised: one concerning the elaboration and meaning attribution of an image and the other the illustration of a concept. The two exercises were applied to 100 13-year-old students of a rural community in Portugal. The exercises were evaluated in terms of fluency, flexibility, originality, elaboration, expressiveness and adequateness. The results reveal statistically significant differences in these dimensions after the completion of second exercise, revealing that it is possible to use elements of the visual code to express ideas in creative ways.

World Journal of Neuroscience 2016年第2期6卷 143-150页

作者： Roberta Márcia torres Kristiana Cerqueira Mousinho Liércio Pinheiro Nathália Costa Toledo Pacheco Piatti Taise Almeida Cavalcante Aline da Silva Amorim Ana Karolina Barros de Jesus Maria Wylianna Oliveira dos Santos Euclides Maurício trindade Filho University Center CESMAC Maceió Brazil

Objective: This study aimed to carry out a topographical analysis of frontal lobe executive function components in post-stroke patients. Methods: A descriptive, cross-sectional study. The assessment using the WCST (Wisconsin Card Sorting Test) included sixteen patients with a clinical diagnosis of CVA and frontal lobe impairment. Results from the two groups were compared (patients with right frontal lobe impairment and patients with left frontal lobe impairment). Statistical analysis was performed using the program “Statistical Package for Social Sciences” (SPSS) Version 20.0. For comparison between groups was used Mann-Whitney test and considered the alpha level of 0.05 on the statistically significant results. Results: There was no statistically significant difference between the groups, thus showing that executive functions are symmetrically distributed across the frontal lobes. Conclusion: Executive functions are symmetrically organized across the two frontal lobes, since the comparison between the groups did not demonstrate a statistically significant difference for any of the variables of WSCT.

BACKGROUND Superior mesenteric artery syndrome(SMAS)is a rare condition,characterized by duodenal obstruction caused by compression of its third part by the superior mesenteric artery(SMA).Most cases of SMAS are associated with weight loss,and the most frequent clinical manifestations are nausea,vomiting,postprandial fullness,and abdominal *** of SMAS is usually conservative,consisting mainly of adequate nutritional support,but in refractory cases surgery may be necessary,with gastrojejunostomy and duodenojejunostomy being the most commonly performed *** SUMMARY We describe the case of a man in his forties with a pre-existing diagnosis of esophageal stricture due to sodium hydroxide ingestion,who suffered significant weight loss after replacement of his jejunostomy *** was admitted to the hospital due to pain and abdominal distension.A computerized tomography scan showed significant distension of the stomach and duodenum with narrowing of the duodenum at the point at which it is crossed by the superior mesenteric artery,thus establishing the diagnosis of *** to the presence of the esophageal stricture,the patient was incapable of emesis;however,passage of a nasogastric tube for decompression was not *** the risk of gastric perforation due to distention,we opted for surgical treatment in the form of a surgical gastrojejunostomy after which he showed complete resolution of all symptoms and was discharged from the hospital 5 d after the *** Diagnosis of SMAS can be challenging in patients with esophageal stenosis,and risk of gastric perforation may preclude conservative treatment.
