Uso de banda dendrométrica na definição de padrões de crescimento individual em diâmetro de árvores da bacia do rio Cuieiras

Este trabalho tem como objetivo analisar padrões de crescimento individual de diversas árvores que ocorrem em duas toposseqüências (direções Norte-Sul e Leste-Oeste), de uma amostra representativa da floresta de terra-firme na Amazônia Central. Foram selecionados de forma aleatória, aproximadamente, 300 indivíduos, sendo 150 em cada toposseqüência, distribuídos em mesmas proporções nas três classes topográficas (platô, encosta e baixio) e nas três classes de diâmetro (10 ≤ DAP < 30 cm; 30 ≤ DAP< 50 cm e DAP≥ 50 cm). Em cada uma dessas árvores foi instalada uma fita metálica, com extremidades parcialmente sobrepostas e ligadas por uma mola; o avanço de uma das pontas, dentro de uma abertura, representa o crescimento em circunferência, que foi medido com um paquímetro digital. As medições foram realizadas mensalmente ao longo de 19 meses, de junho/1999 a dezembro/2000; neste estudo foram considerados apenas os 12 meses do ano 2000. O padrão individual de crescimento em diâmetro varia muito com o passar dos meses (p = 0,00) e apenas razoavelmente quando os meses são interagidos com as classes de diâmetro (p 0,08); por outro lado, há fraca uma evidência (p = 0,25) quando as classes topográficas são acrescentadas na interação anterior e praticamente nenhuma evidência (p = 0,89) quando é analisada a interação meses e classes topográficas. Dentre todas as árvores selecionadas (300 indivíduos), foram mantidas na análise 272 indivíduos. A média do incremento anual em diâmetro, considerando as 272 árvores monitoradas, foi de 1,64 ± 0,21 mm (p = 0,05), ficando dentro do intervalo dos incrementos obtidos no BIONTE e FLONA Tapajós, que é de 1,5 a 2 mm por ano.

Assessing student individual performance within PBL teams: findings from the implementation of a new mechanism

This paper reports on the experience of the implementation of a new mechanism to assess individual student contribution within project work, where students work in teams to solve a large-scale open-ended interdisciplinary project. The study takes place at the University of Minho, with first year engineering students, enrolled in the Industrial Management and Engineering (Integrated Masters) degree. The aim of this paper is to describe the main principles and procedures underlying the assessment mechanism created and also provide some feedback from its first implementation, based on the students, lecturers and tutors perceptions. For data collection, a survey was sent to all course lecturers and tutors involved in the assessment process. Students also contributed with suggestions, both on a workshop held at the end of the project and also by answering a survey on the overall satisfaction with PBL experience. Findings show a positive level of acceptance of the new mechanism by the students and also by the lecturers and tutors. The study identified the need to clarify the criteria used by the lecturers and the exact role of the tutor, as well as the need for further improvement of its features and procedures. Some recommendations are also issued regarding technical aspects related to some of the steps of the procedures, as well as the need for greater support on the adjustment and final setting of the individual grades.

Intra and inter-individual differences in social intelligence of Portuguese students

Social intelligence is a favorable condition for career decision-making and development. The social intelligence indices of Portuguese students in school years prior to a career transition are characterized and intra and interindividual differences are analyzed. Participants were 1095 students (552, 50.4% women) with a mean age of 14.78 years (SD = 1.86), in the 8th (542, 49.5%), 10th (295, 26.9%) and 11th (258, 23.6%) grades. The Cognitive Test of Social Intelligence (PCIS) was administered at two moments, six months apart. Results indicate that the 8th grade obtained higher average scores in Problem Solving, Motivation and Self-confidence (time 1), while the 10th grade obtained better results in Problem Solving, Motivation and Familiarity (time 2). Between the assessment moments, all school years register an increase in Problem Solving and Self-confidence in social situations. These results constitute favorable psychological conditions for the promotion of ethical questioning in career guidance interventions.

The contribution of phenolic acids to the anti-inflammatory activity of mushrooms: Screening in phenolic extracts, individual parent molecules and synthesized glucuronated and methylated derivatives

In the present study, the ethanolic extracts of fourteen edible mushrooms were investigated for their anti-inflammatory potential in LPS (lipopolysaccharide) activated RAW 264.7 macrophages. Furthermore the extracts were chemically characterized in terms of phenolic acids and related compounds. The identified molecules (p-hydroxybenzoic, p-coumaric and cinnamic acids) and their glucuronated and methylated derivatives obtained by chemical synthesis were also evaluated for the same bioactivity, in order to establish structure-activity relationships and to comprehend the effects of in vivo metabolism reactions in the activity of the compounds. The extracts of Pleurotus ostreatus, Macrolepiota procera, Boletus impolitus and Agaricus bisporus revealed the strongest anti-inflammatory potential (EC50 values 96 ± 1 to 190 ± 6 µg/mL, and also the highest concentration of cinnamic acid (656 to 156 µg/g), which was also the individual compound with the highest anti-inflammatory activity. The derivatives of p-coumaric acid revealed the strongest properties, specially the derivative methylated in the carboxylic group (CoA-M1) that exhibited similar activity to the one showed by dexamethaxone used as anti-inflammatory standard; by contrast, the derivatives of p-hydroxybenzoic revealed the lowest inhibition of NO production. All in all, whereas the conjugation reactions change the chemical structure of phenolic acids and may increase or decrease their activity, the glucuronated and methylated derivatives of the studied compounds are still displaying anti-inflammatory activity.

Cerebral perfusion and automated individual analysis using SPECT among an obsessive-compulsive population

OBJECTIVE: To make individual assessments using automated quantification methodology in order to screen for perfusion abnormalities in cerebral SPECT examinations among a sample of subjects with OCD. METHODS: Statistical parametric mapping (SPM) was used to compare 26 brain SPECT images from patients with OCD individually with an image bank of 32 normal subjects, using the statistical threshold of p < 0.05 (corrected for multiple comparisons at the level of individual voxels or clusters). The maps were analyzed, and regions presenting voxels that remained above this threshold were sought. RESULTS: Six patients from a sample of 26 OCD images showed abnormalities at cluster or voxel level, considering the criteria described above, which represented 23.07%. However, seven images from the normal group of 32 were also indicated as cases of perfusional abnormality, representing 21.8% of the sample. CONCLUSION: The automated quantification method was not considered to be a useful tool for clinical practice, for analyses complementary to visual inspection.

Laboratory assessment of the hypertensive individual. Value of the main guidelines for high blood pressure

OBJECTIVE: To determine if abnormal laboratory findings are more common in individuals with hypertension and in those with other risk factors, such as obesity, smoking and alcohol ingestion. METHODS: A study was carried out in the general outpatient clinics of a university hospital (145 individuals without previous diagnosis of hypertension) and the following variables were assessed: high blood pressure (as defined by the VI Joint National Committee on Prevention, Detection and Treatment of High Blood Pressure - VI JNC), obesity [calculated using body mass index (BMI)], tobacco use, and alcoholic ingestion. The laboratory examinations consisted of the following tests: hemogram, glycemia, uric acid, potassium, total/HDL-fraction cholesterol, triglycerides, calcium and creatinine. RESULTS: High blood pressure was not associated with a higher number of abnormal laboratory tests. Hypertensive individuals with a BMI > or = 25kg/m² or normotensive obese individuals, however, had a higher frequency of diabetes (12X), hypertriglyceridemia (3X), and hypercholesterolemia (2X), as compared with hypertensive individuals with BMI <25kg/m² and preobese/normal weight normotensive individuals. CONCLUSION: High blood pressure is not associated with a higher frequency of abnormal laboratory tests. The association of high blood pressure and obesity, however, increases the detection of diabetes and dyslipidemias.

Detección de circovirus pocino tipo II en cerdos que presentan diarrea en criaderos intensivos. Detection of porcine circovirus type II in pigs that present diarrhea in intensive hatcheries.

Se propone detectar la presencia del agente etiológico circovirus porcino (CVP) en cerdos con diarrea. El cual se considera un patógeno emergente importante asociado a diferentes sindromes y enfermedades porcinas. Se comunicó a nivel internacional en 1997 y en Argentina fue descripto en el 2003 en animales de cria extensiva, aunque se encuentra en los diferentes sistemas de producción. Su presencia causa grandes pérdidas económicas, ya que muchas veces no tiene una sintomatología clínica, sino que se manifiesta subclinicamente. En la provincia de Córdoba no se han realizado estudios sistemáticos para determinar la presencia de circovirus. Además, en animales que presentan diarrea no se ha realizado un relevamiento de la presencia del CVP y su asociación con el cuadro clínico. Diversos investigadores estan viendo la necesidad de incluir al CVP a la hora de pensar en los diagnósticos etiológicos, en aquellos que no solo presentan índices productivos ineficientes sino también que no responden a la terapia antimicrobiana. Es agente causal del Sindrome de Desmedro Posdestete y podria favorecer la acción de otros agentes patógenos que actuarían tanto en Sistema Respirastorio como en Sistema Digestivo. La complejidad del trabajo radica en demostrar lo antes mencionado a traves de las lesiones a observar en los tejidos y la determinación de la presencia del agente. La ejecución de este estudio sería un importante aporte a la producción porcina, en donde este agente produce importantes pérdidas económicas. La metodología, así como los resultados obtenidos serán útiles en la formación de recursos humanos aplicados a la investigación y transferidos directamente a la docencia. Hipotesis: Establecer la presencia del CVP en cerdos con signos clinicos de enteropatías Objetivos: Determinar en cortes histopatológicos de intestino y ganglio mesentério, lesiones compatibles con CVP; Determinar por inmunohistoquímica la presencia del antígeno CVP en las muestras. Identificar las células en las que se encuentre el antígeno. Materiales y método: Muestreo a campo y toma de muestra. En diferentes establecimientos porcinos, de aquellos animales que presenten el cuadro clínico de diarrea, serán elegidos 3 animales aleatoriamente para sacrificio y realización de la técnica de necropsia. Se tomarán muestras de intestino delgado y ganglio mesentérico que serán fijadas en formol; la técnica histopatológica y su lectura tendrán fin de encontrar lesiones compatibles con circovirus porcino tipo II; Realización de la técnica de inmunohistoquímica con anticuerpo monoclonal, para la detección del CVP en los tejidos; Interpretación de resultados; Publicación de los resultados.

A nutrient balance model for typical Irish farming systems

The twin objectives of the work described were to construct nutrient balance models (NBM) for a range of Irish animal production systems and to evaluate their potential as a means of estimating the nutrient composition of farm wastes. The NBM has three components. The first is the intake of nutrients in the animal's diet. The second is retention or the nutrients the animal retains for the production of milk, meat or eggs. The third is the balance or the difference between the nutrient intake and retention. Data on the intake levels and their nutrient value for dairy cows, beef cattle, pigs and poultry systems were assembled. Literature searches and interviews with National experts were the primary sources of information. NBMs were then constructed for each production system. Summary tables of the nutrient values for the common diet constituents used in Irish animal production systems, the nutrient composition of the animal products and the NBMs (nutrient intake, retention and excretion) for a range of production systems were assembled. These represent the first comprehensive data set of this type for Irish animal production systems. There was generally good agreement between the derived NBMs values and those published in the literature. The NBMs were validated on a number of farms. Data on animal numbers, fertiliser use, concentrates inputs and production output were recorded on seven farms. Using the data a nutrient input/output balance was constructed for each farm. This was compared with the NBM estimate of the farm nutrient balance. The results showed good agreement between the measured balance and the NBM estimate particularly for the pig and poultry farms. However, the validation emphasised the inherent risks associated with NBMs. The average values used for feed intake and production parameters in the NEMs may result in the under or over estimate of actual nutrient balances on individual farms where these variables are substantially different. On the grassland farms there was a poor correlation between the input/output estimate and the NBM. This possibly results from the omission of the soil's contribution to the nutrient balance. However, the results indicate that the NBMs developed are a potentially useful tool for estimating nutrient balances. They also will serve to highlight the significant fraction of the nutrient inputs into farming systems that are retained on the farm. The potential of the NBM as a means of estimating the nutrient composition of farm wastes was evaluated on two farms. Feed intake and composition, animal production, slurry production was monitored during the indoor winter feeding period. Slurry samples were taken for analysis. The appropriates NBMs were used to estimate the nutrient balance for each farm. The nutrient content of the slurry produced was calculated. There was a good agreement between the NBM estimate and the measured values. This preliminary evaluation suggests that the NBM has a potential to provide the farmer with a simple means of estimating the nutrient value of his slurry.

Does bounded rationality lead to individual heterogeneity? The impact of the experimentation process and of memory constraints

In this paper we explore the effect of bounded rationality on the convergence of individual behavior toward equilibrium. In the context of a Cournot game with a unique and symmetric Nash equilibrium, firms are modeled as adaptive economic agents through a genetic algorithm. Computational experiments show that (1) there is remarkable heterogeneity across identical but boundedly rational agents; (2) such individual heterogeneity is not simply a consequence of the random elements contained in the genetic algorithm; (3) the more rational agents are in terms of memory abilities and pre-play evaluation of strategies, the less heterogeneous they are in their actions. At the limit case of full rationality, the outcome converges to the standard result of uniform individual behavior.

Marcação individual de triatomíneos para estudos comportamentais e ecologicos

Idealizou-se uma técnica de marcação de insetos adultos, visando principalmente à identificação individual de triatomineos, que consiste na elaboração de códigos correspondentes a números, através de cinco cores basicas (vermelho, branco, azul, verde e amarelo) representadas por pintas coloridas feitas com tinta esmalte e depositadas do pronoto ao escutelo do inseto manualmente, com um fino pincel de seda. As pintas não devem se estender às asas sobrepostas, porque estas mudam constantemente de posição, encobrindo assim a marcação. A tinta é indelével e, por não apresentar toxicidade, não afeta a longevidade e o comportamento dos insetos. A técnica pode ser utilizada tanto para insetos no laboratório quanto no campo principalmente em trabalhos relacionados à Ecologia e ao Comportamento.
