TRUNK BIOMASS ESTIMATION BY DIFFERENT METHODS IN A SUBTROPICAL FOREST

The aim of the work was to estimate trunk biomass in a Deciduous Seasonal Forest by using direct and indirect methods. The data were obtained from seven 12 x 12 m plots, bringing to a total of 64 trees. Trunk biomass was determined by direct method and indirect methods which consisted of: 1) Real Volume (RV) of the trunk multiplied by the Weighted Average (WA) and Arithmetic Average (AA) of the specific basic mass of the wood species found, resulting in Real Volume for Weighted Average (RVWA)  and Real Volume for Arithmetic Average (RVAA), and 2) by the Estimated Volume (EV) multiplied by WAand by AA, resulting in Estimated Volume for Weighted Average (EVWA)  and Estimated Volume for Arithmetic Average (EVAA). The trunk biomass of the three plots determined by the direct method was 11,451 Kg. The indirect method that had the most similar to the real trunk biomass (TB) value result was the EVAA (13,142 Kg), and the one that showed the largest difference was the RVWA,which was estimated at 20,061 Kg. The t-test showed significant difference of trunk biomass for indirect methods that used the RV; and the methods that used the EV did not differ statistically.Key-words: Forest biomass; arboreal biomass; Decidual Stational Forest.ResumoEstimativa da biomassa do fuste por diferentes métodos em floresta subtropical. O trabalho teve como objetivo estimar a biomassa do fuste em um fragmento de Floresta Estacional Decidual Montana utilizando métodos diretos e indiretos. Os dados de biomassa foram obtidos de sete parcelas de 12 x 12 m, totalizando 64 árvores. A biomassa do fuste foi determinada pelo método direto e por métodos indiretos que consistiram em: 1º) Volume Rigoroso (VR) do fuste multiplicado pela Média Ponderada (MP) e Média Aritmética (MA) da massa específica básica da madeira das espécies encontradas, resultando em Volume Rigoroso para Média Ponderada (VRMP)e Volume Rigoroso para Média Aritmética (VRMA), e 2º) pelo Volume Estimado (VE) multiplicado pela MPe pela MA, resultando em Volume Estimado para Média Ponderada (VEMP) e Volume Estimado para a Média Aritmética (VEMA). O TB das três parcelas determinado diretamente foi de 11451 Kg. O método indireto que mais se aproximou da biomassa do fuste foi o VEMA (13142 Kg), e o que apresentou a maior diferença foi o VRMP que totalizou 20061 Kg. O teste t indicou diferença significativa da biomassa do fuste para os métodos indiretos que utilizam o VR; e os métodos que utilizaram o VE não diferiram estatisticamente.Palavras-chaves: Biomassa florestal; biomassa arbórea; Floresta Estacional Decidual

Quality of aneroid sphygmomanometers used by health professionals in the units of the SUS Cacoal – RO

Blood pressure is a clinical variable of great medical importance, and its correct measurement depends on the precise measurement of blood pressure. This research examined the quality of aneroid sphygmomanometers used in outpatient and hospital services SUS Cacoal-RO. This is a cross-sectional study that analyzed 54 sphygmomanometer in use in health services Cacoal RO. The devices were analyzed for physical conditions and calibration. The devices analyzed 37.04% of the devices were in use in Basic Health Units (UBS) and 62.96% in Hospital Services. The physical conditions of the devices were analyzed by direct examination of the same and the calibration was checked against a mercury column, checking the correlation values every 20 mmHg from 0mmHg to 240mmHg. When checking the state of conservation of cuffs, 70.37% presented themselves clean and 81.48% intact. Of the total sphygmomanometers, 79.63% are uncalibrated. The most unreliable measurements was performed in hospital services (p <0.001). From the results, it is concluded that most sphygmomanometers of Cacoal SUS services is not properly calibrated, especially in hospital services, which can lead to incorrect assessments of blood pressure compromising diagnoses and medical procedures resulting from this variable. Our results reflect the need for improvement in the quality of aneroid sphygmomanometers used in SUS units Cacoal-RO. Keywords: sphygmomanometer, quality, calibration

Effects of radiofrequency on the healing of skin wounds in rats: analysis using digital planigraphy and histological evaluation

INTRODUCTION: Given the extensive use of plastic surgery and the search for better aesthetic and functional results, it is necessary to research ways to improve healing and scarring. The objective is to evaluate the effects of three radiofrequency (RF) sessions in healing the skin of mice. METHODS: Forty-eight rats were divided into four groups by day of sacrifice and treatment (RF group: RG; control group: CG). Dissection of the excisional wound of 2 cm x 2 cm (4 cm²) was performed and a 6-mm punch was used to hold two excisional wounds 0.6 cm in diameter. After 24 h, radiofrequency was performed using Spectra® directly on the wound in the dorsal region for 7 minutes at 38ºC. This was repeated three times on alternate days. For the control group, the radiofrequency protocol was performed with the device switched off. RESULTS: A larger area of the square wound was measured on postoperative day three in RG (RG7: 3.3 cm² ± 0.7 cm² vs. CG7: 2.4 cm² ± 0.4 cm²; p = 0.009). On day 14, the square wound in RG was greater than in CG (RG14: 1.9 cm² ± 0.5 cm² vs. CG14: 1.0 cm² ± 0.3 cm²; p = 0.001). There was a 90% closure of wounds in CG14. In RG14, 60% of the wounds were re-epithelized while 40% remained ulcerated. In CG7, 70% of the remaining wounds were ulcerated and 30% were re-epithelized. In RG7, 8% were re-epithelized and 92% remained ulcerated. CONCLUSION: Radiofrequency has a negative influence on the healing process, as indicated by mice that received radiofrequency having a persistent ulcerated wound

Biomass of a fragment of the montane seasonal deciduous forest the south Brazil

The objective the work was to quantify the biomass using the destructive method of a forest fragment located in the South of Brazil. The study was conducted in fragment of Montane Seasonal Deciduous Forest with approximately 55 ha, centered at the coordinates S 27˚23’44” and W 53˚25’59”. For that, three plots of 12x12 m were installed. All plants with diameter at breast height (DBH) greater than 5 cm were identified at the species level. All trees with DBH&gt;10 cm had the following information collected: DBH, total height (h), height at the morphological inversion point (MIP) and the diameter at 0%, 25%, 50%, 75% and 90% of the MIP height. As result, we verified that trees with DBH&gt; 10 cm represent more than 90% of the total biomass (345.2 Mg ha-1). The estimated biomass of leaf litter was 12.4 Mg ha-1. The stock of dry aboveground biomass and litter for the study area was 380.5 Mg ha-1

Thoracic lymphadenopathy in benign diseases: A state of the art review

Lymphadenopathy is a common radiological finding in many thoracic diseases and may be caused by a variety of infectious, inflammatory, and neoplastic conditions. This review aims to describe the patterns of mediastinal and hilar lymphadenopathy found in benign diseases in immunocompetent patients. Computed tomography is the method of choice for the evaluation of lymphadenopathy, as it is able to demonstrate increased size of individual nodes, abnormalities of the interface between the mediastinum and lung, invasion of surrounding fat, coalescence of adjacent nodes, obliteration of the mediastinal fat, and hypo- and hyperdensity in lymph nodes. Intravenous contrast enhancement may be needed to help distinguish nodes from vessels. The most frequent infections resulting in this finding are tuberculosis and fungal disease (particularly histoplasmosis and coccidioidomycosis). Sarcoidosis is a relatively frequent cause of lymphadenopathy in young adults, and can be distinguished from other diseases - especially when enlarged lymph nodes are found to be multiple and symmetrical. Other conditions discussed in this review are silicosis, drug reactions, amyloidosis, heart failure, Castleman's disease, viral infections, and chronic obstructive pulmonary disease.
