An overview of application of micromechanical models in ductile fracture analysis of welded joints
Authors: Rakin M. , Medjo B. , Gubeljak N. , Sedmak A.
Published: June 2020

Fracture of welded joints has been an important research and industrial topic for a long time, having in mind the key role of welded joints in ensuring the safe operation and integrity of welded structures. This work contains an overview of application of micromechanical models to ductile fracture of welded joints. The main benefit of these models, in comparison with the classical fracture mechanics approach, is consideration of the local quantities (stress and strain) in prediction of damage development. The damage is quantified through the value of the damage parameter, which is typically related to the void nucleation, growth and coalescence for ductile fracture of metallic materials, i.e. the description of the material can be related to the actual material behaviour during fracture. Most of the presented studies, including those published by the present authors, are performed on steel as the base material, and the rest deal with aluminium alloys.

Published: June 2020

Clinical Relevance

Preparation designs for bondable partial coverage restorations are varied. As little as 1 mm of thickness of a remaining buccal cusp can be kept when restoring maxillary premolars with bondable partial coverage restorations.

Indirect partial coverage restorations have become increasingly popular in recent years as new and improved adhesive materials have been developed. These restorations can preserve substantial amounts of tooth structure. However, there are some aspects of indirect partial coverage restorations for which no clear protocol exists. This study investigated the minimal thickness of the nonfunctional cusp that must be left in a bondable ceramic partial coverage restoration in order to resist compressive force. Ninety sound human maxillary premolar teeth were obtained and used in one of the following three ways. Ten of the sound teeth were used as a control without further preparation. Forty other sound teeth had cavities designed and were tested as “unrestored teeth.” The remaining 40 sound teeth received not only cavities but also restoration and were tested as “restored teeth.” Both the restored group and the unrestored group were prepared either with an overlay or with varying buccal cusp thicknesses of 1, 2, or 3 mm. In total, there were nine experimental groups with 10 in each group (n=10). The prepared teeth were digitally scanned, and the restorations were designed and fabricated from IPS e.max computer-aided design (CAD) software using a CAD/CAM machine (CEREC MC XL, Dentsply Sirona, Bensheim, Germany). The restorations were cemented with resin cement (Panavia V5). All samples underwent thermocycling and dynamic fatigue simulating approximately one year of actual use. All the teeth were then subjected to compressive load until the point of fracture, and the mode of each fracture was analyzed. Results show that the fracture resistance of the restored groups was significantly higher than the nonrestored groups (p<0.001) and the sound teeth (p<0.05). Crucially, this study determined that 1 mm of remaining buccal cusp thickness in bondable partial coverage restorations for maxillary premolars is sufficient to withstand normal use of the tooth without breakage.

How many alcohol-attributable deaths and hospital admissions could be prevented by alternative pricing and taxation policies? Modelling impacts on alcohol consumption, revenues and related harms in Canada
Authors: Stockwell Tim , Churchill Samuel , Sherk Adam , Sorge Justin , Gruenewald Paul
Published: June 2020

Introduction

In 2017, Canada increased alcohol excise taxes for the first time in over three decades. In this article, we describe a model to estimate various effects of additional tax and price policies that are predicted to improve health outcomes.

Methods

We obtained alcohol sales and taxation data for 2016/17 for all Canadian jurisdictions from Statistics Canada and product-level sales data for British Columbia. We modelled effects of alternative price and tax policies - revenue-neutral taxes, inflation-adjusted taxes and minimum unit prices (MUPs) - on consumption, revenues and harms. We used published price elasticities to estimate impacts on consumption and revenue and the International Model for Alcohol Harms and Policies (InterMAHP) to estimate impacts on alcohol-attributable mortality and morbidity.

Results

Other things being equal, revenue-neutral alcohol volumetric taxes (AVT) would have minimal influence on overall alcohol consumption and related harms. Inflation-adjusted AVT would result in 3.83% less consumption, 329 fewer deaths and 3762 fewer hospital admissions. A MUP of $1.75 per standard drink (equal to 17.05mL ethanol) would have reduced consumption by 8.68% in 2016, which in turn would have reduced the number of deaths by 732 and the number of hospitalizations by 8329 that year. Indexing alcohol excise taxes between 1991/92 and 2016/17 would have resulted in the federal government gaining approximately $10.97 billion. We estimated this could have prevented 4000-5400 deaths and 43 000-56 000 hospitalizations.

Conclusion

Improved public health outcomes would be made possible by (1) increasing alcohol excise tax rates across all beverages to compensate for past failures to index rates, and (2) setting a MUP of at least $1.75 per standard drink. While reducing alcohol-caused harms, these tax policies would have the added benefit of increasing federal government revenues.
Autonomy, competence and relatedness and cannabis and alcohol use among youth in Canada: a cross-sectional analysis
Authors: Enns Aganeta , Orpana Heather
Published: June 2020

Introduction

There has been increasing attention on preventing problematic youth substance use in light of concerns about rates of use and policy changes in Canada. Strengths-based approaches that emphasize protective factors, including positive mental health, are at the forefront of current prevention recommendations. However, there is a dearth of research on the association between positive mental health and substance use among youth. This study examines the associations between cannabis and alcohol use among youth and positive mental health as measured through the lens of self-determination theory.

Methods

Secondary analyses of the 2014/2015 Canadian Student Tobacco, Alcohol and Drugs Survey (CSTADS) were conducted. Participating Grade 7 to 12 students residing in Canada completed the Children's Intrinsic Needs Satisfaction Scale (CINSS), which measures autonomy, competence and relatedness, and answered questions that measure past 30-day and more frequent cannabis use, alcohol use and binge-drinking. The associations between autonomy, competence and relatedness and substance use, stratified by sex, were examined using logistic regression.

Results

Fully adjusted models revealed that relatedness and competence were associated with lower odds of 30-day and more frequent cannabis use, alcohol use and binge-drinking. Higher autonomy was associated with higher odds of these behaviours. All associations were significant with the exception of competence and more frequent cannabis use among boys, and autonomy and more frequent alcohol use among girls.

Conclusion

The findings offer new evidence on the associations between positive mental health and substance use among youth, specifically how autonomy, competence and relatedness are associated with cannabis use, alcohol use and binge-drinking. This evidence can be used to inform health promotion and substance use prevention programs.
A Level-Wise Periodic Tree Construction Mechanism for Sleep Scheduling in WSN
Authors: Tarasia Nachiketa , Ratna Swain Amulya , Roy Soham , Narayana Kar Udit
Published: June 2020

The wireless sensor network (WSN) has been extensively used to monitor and control the natural ecosystem on a large scale like air quality, natural life, etc. Low battery power,low storage, and limited processing ability are the most critical areas of concern in WSN. To reduce energy utilization, the sensor nodes in WSN work in a cyclic process between active and sleep mode. A certain number of nodes are chosen active and they are responsible for sensing as well as data transmission and rest of the nodes are gone to sleep. In order to lengthen the lifetime of network, in this paper we proposed a level wise periodic tree construction algorithm that uses a specific set of nodes to participate in tree construction, instead of all the nodes, to minimize the energy consumption. In this proposed approach, the main idea is to put the nodes, which are currently active and have already spent a significant amount of energy, to sleep mode, while giving chances to the leaf nodes, which has comparatively spent less energy, to become an active node and maintain connectivity. The performance of the proposed protocol is evaluated using the Castalia simulator. The simulation results show that the proposed level-wise periodic tree construction approach increases the durability of the network in conjunction with the non-level approach.
AN INTEGRATED PUBLIC ART IN PUTRAJAYA URBAN LANDSCAPE
Authors: Misni Alamah Misni , Suran Anwar
Published: June 2020

The art found in public space represents a local social and cultural situation, as well as the artistic and aesthetic tendencies. There is a close relationship between the public art and the city landscape. Public art is part of the broader visual environment of buildings, landscapes, and infrastructure. It can promote a sense of place, contribute to legibility or wayfinding, and support efforts to quality urban design. It can be in the form of sculpture, street furniture, mural, and even fountain structure. This research focuses on the user's perception and appreciation of integrated public art in the Putrajaya urban landscape. Data was collected using qualitative and quantitative methods. The case study data collections were conducted through a survey, observation, and distribution of questionnaires. The case study was carried out in the Putrajaya urban landscape. Putrajaya was selected as a case study because it is the new administrative capital of Malaysia that has seen the need to be distinctively outstanding in both its characteristics and development. Putrajaya has revealed the influence of public art in enforcing and strengthening the identity of the city. Subsequently, the recommendation has been made to enhance the planning process and management system by the local authority in the Putrajaya urban landscape. Therefore, this research will help to generate the social awareness and understanding of the effort of integrating public art into the Malaysian urban landscape. Keywords: Putrajaya, planning, public art, sense of place, urban landscape
Migrating Towards Growth and Oblivion? A Contextual Account of the Lives and Work of Spanish-Mexican Composers María Teresa Prieto and Emiliana de Zubeldía
Authors: Chibici-Revneanu Claudia Christina
Published: June 2020

Este artículo se centra en la vida y obra de las compositoras hispano-mexicanas del siglo XX María Teresa Prieto y Emiliana de Zubeldía, a partir de una metodología interdisciplinaria que reúne aspectos de musicología feminista, género y migración, así como de estudios culturales. El objetivo es analizar sus biografías en el contexto de la escasa visibilidad de las mujeres en la representación de la diáspora y el discurso musical. El texto muestra cómo el desplazamiento geográfico contribuyó a su desarrollo creativo y a su carrera, mediante el acceso a redes significantes, procesos enriquecedores de transferencia cultural, su involucramiento en afirmaciones rivales de identidad nacional/regional y su liberación de normas de género (musical) restrictivas. Sin embargo, las ventajas contextuales que tuvieron demostraron ser insuficientes frente a las grandes estructuras discriminatorias de género en la esfera musical que generalmente han truncado las trayectorias femeninas mediante el olvido.

Published: June 2020

Bacillus cereus, usually ingested by food, can cause two types of disease due to the presence of toxins: vomiting and diarrhea syndrome. Systemic infections can also occur. The aim was to detect genes for enterotoxins (hblA, entFM) and emetic toxin (cer) and to investigate the genetic heterogeneity of B. cereus isolates from food, environment and human stool. Identification of B. cereus was performed by means of selective medium, classical biochemical test and polymerase chain reaction (PCR). Toxin genes were detected by PCR. Typing was performed by random amplified polymorphic DNA (RAPD). EntFM gene was present in all stool and food samples and in 28/30 environmental isolates. HblA gene was present in 29/30 stool, 23/30 food and 24/30 environmental isolates. Cer gene was present in 30/30 stool, 28/30 food and 25/30 environmental isolates. The RAPD results show high heterogeneity among the isolates from each group. In the cumulative dendrogram, representative isolates from all three groups formed two clusters with a difference of 53%. The detection of toxin genes in all B. cereus isolates indicated these bacteria as potentially pathogenic and a serious threat for human health. The presence of isolates from all three groups in the same cluster suggests the existence of similar strains in the environment, food and patients, which is in line with the circulation of strains in nature through the food chain.

Published: June 2020

In the Balkan region, the state of sheep welfare is little known. In this context, the assessment of sheep welfare is important for the identification of health and behavioral problems that affect these animals, along with the deficiencies present in the environment. The study was conducted during the winter season on a farm of 220 autochthonous breed Vlašićka Zackel sheep reared in extensive systems on the mountain regions of Bosnia and Herzegovina. A total of 65 ewes, aged 2–4 years, were observed. The welfare assessment was performed according to the AWIN protocol for sheep. The authors found the following issues: dry ewes were significantly fat (p<0.001) in regard to pregnant and lactation ewes; 42.11% of pregnant ewes were thin while 31.25% of dry ewes were fat; most of the assessed animals (78.46%) had dry or damp, slightly soiled fleece; 32.31% of animals had lesions on face/muzzle while ocular discharge, respiratory problems, mild mastitis and minor lameness were present in 16.92%, 4.62%, 15.38% and 7.69% sheep, respectively. All animals showed a negative relationship with humans. Using this methodology, the welfare problems in animals may be detected, and thus certain segments in the production cycle may be improved. The on-farm welfare assessment is highly recommended for emphasizing the key points in improving sheep welfare in Balkan countries.

The CT inspection method allowed to rate the density of defects hidden inside a material, which has a significant role in the live material. The method allows to evaluate the reliability of tensile test’s results. In our analysis, the position of crack propagation was determined by CT, and the tensile test was performed to check the accuracy of the nondestructive method. The tensile tests were performed on Inconel 738LC [1] samples.
In vitro Production of Porcine Embryos: Current Status and Possibilities – A Review
Authors: Poniedziałek-Kempny Katarzyna
Published: June 2020

This paper presents the current possibilities, state of knowledge and prospects of in vitro production (IVP) of pig embryos, which consists of in vitro oocyte maturation, in vitro fertilization and in vitro embryo culture. In pigs, oocyte maturation is one of the most important stages in the embryo IVP process. It determines the oocyte’s fertilization ability as well as its embryonic development. Through many research studies of the proper selection of oocytes and appropriate maturation medium composition (especially the addition of various supplements), the in vitro maturation of pig oocytes has been significantly improved. Recent studies have demonstrated that modifications of the diluents and in vitro fertilization media can reduce polyspermy. Furthermore, several adjustments of the porcine culture media with the addition of some supplements have enhanced the embryo quality and developmental competence. These updates show the progress of IVP in pigs that has been achieved; however, many problems remain unsolved.
Neuregulin 1 (NRG-1) as a Neuronal Active Substance in the Porcine Intrahepatic Nerve Fibers in Physiological Conditions and Under the Influence of Bisphenol a (BPA )
Authors: Rytel Liliana , Lozano Marcelo Alarcón , Gonkowski Sławomir
Published: June 2020

Bisphenol A (BPA ) is a substance commonly used in the production of plastics. Previous studies have described that it shows multidirectional harmful effects on the living organism. It is known that BPA causes liver damage, but knowledge about the roles of intrahepatic nerves in these mechanisms is extremely scanty. On the other hand, the exact roles of some neuronal substances in the nervous structures located in the liver still remain unknown. One of such substance, which is allocated a role in the stimulation of cell survival is neuregulin 1 (NRG-1). The aim of the present study was to investigate the distribution of NRG-1-like immunoreactive (NRG-1-LI) nerves in the liver in physiological conditions and under the influence of various doses of BPA using routine double immunofluorescence staining. The results (for the first time) show the presence of NRG-1 in the intrahepatic nerves, and co-localization of NGR-1 with neuronal isoform of nitric oxide synthase (nNOS) and vasoactive intestinal polypeptide (VIP). Moreover, it has been observed that high doses of BPA increase the density of NRG-1-LI intrahepatic nerves and the degree of co-localization of NRG-1 with VIP. These observations suggest that NRG-1 located in intrahepatic nerves may play functions in processes connected with liver damage and/or regeneration under the impact of BPA.

Published: June 2020

The aim of this study was to determine the concentrations and emissions of greenhouse and odorous gases in different types of dairy cattle housing systems with the use of Fourier-transform infrared (FTIR) spectroscopy. The study was performed in autumn and winter in four types of dairy cattle barns with different process and technical systems (free-stall, deep litter – FS-DL; free-stall, sub-floor manure storage – FS-SFM; free-stall, litter in stalls – FS-LS; tie-stall, litter in stalls – TS-LS) in northern Poland. Analyses of gaseous mixtures in barn air were conducted by infrared spectrometry with the multi-component Gasmet DX4030 analyzer. A total of 200 measurement spectra were acquired and subjected to qualitative and quantitative analyses with the Calcmet Professional program with a library of reference spectra for 200 chemical compounds. The results of the study indicate that housing systems and the technological solutions applied in barns exert a considerable influence on the production of greenhouse and odorous gases. Free-stall housing with slatted floors and sub-floor manure storage appears to be the optimal solution for reducing the animals’ exposure to the presence of the analyzed chemical compounds in air, improving animal welfare and minimizing GHG emissions to the environment (considering the optimal ventilation rate). It should be noted that the concentrations of other potentially harmful compounds, for which the maximum safe levels have been specified, were also relatively low in the remaining systems, which points to the observance of high sanitary standards and the use of efficient ventilation systems in the evaluated barns.

Published: June 2020

Common carp (Cyprinus carpio) is the most farmed freshwater fish worldwide. In recent years, use of natural products in fish diets has become popular in aquaculture, to improve fish health and growth performance. The present study investigated the effects of essential oil from the leaves of Monterey cypress (Cupressus macrocarpa; CMEO) on growth performance and blood parameters in common carp fingerlings. Identification of 96.1% of the CMEO total volatile components was achieved, with the highest contents for terpinen-4-ol and α-pinene, at 22.9% and 47.7%, respectively. After 60 days of feeding of the fingerlings with supplemented diets without CMEO (CMEO 0%) and with CMEO at 0.5%, 0.75% and 1%, the best growth performance was seen for those fish fed with the CMEO 0.5% diet. No significant differences were seen for the haematological parameters and blood cell indices versus CMEO 0%. Serum glucose, triglycerides, cholesterol and glutamic pyruvic transaminase were significantly reduced in the fingerlings fed with the CMEO 0.5% diet versus CMEO 0%. Thus, CMEO oil as a 0.5% dietary supplement can be used to improve the growth performance and health status of the common carp without any adverse effects seen.

The issue of carbon monoxide and nitrogen oxides emissions into the atmosphere is very current. This article thus focuses on the assessment of elemental composition of selected herbal biomass species and emission concentrations during combustion in a commonly available grate combustion device for briquetted fuel. In tests, emission concentrations were evaluated in contrast to the oxygen concentration in flue gas and flue gas temperatures. Samples of camelina (Camelina sativa), giant miscanthus (Miscanthus gigantheus), reed canary grass (Phalaris arundinacea L.) and sorghum (Sorghum bicolor) were used. Elementary and stoichiometric combustion analyses were conducted for these samples (LECO AC-600 semi-automatic calorimeter, CHN628 + S elemental analyser and LECO TGA-701 analyser). Analyses of C, H, N and S concentrations and calorific values showed that samples of briquetted herb biomass had insignificant differences and could be used for energy purposes without limitation. The limiting factor was the high amount of ash, which amounted to 6.59% of dry weight in reed canary grass briquette sample. Furthermore, a high percentage (1.91% wt.) of nitrogen was observed in reed canary grass briquettes. Such a high amount of nitrogen during combustion tests resulted in an increase in NOx emission levels in flue gas of the Phalaris arundinacea L. sample, in which it reached the maximum concentration of 375.20 mg·m−3. The combustion tests showed that even under steady-state conditions, high concentrations of carbon monoxide could not be avoided for tested briquetted biofuels without active regulation of the combustion process.

The purpose of this study was to theoretically and practically investigate the thermo-technical properties of two bedding surface materials under real farm conditions during the hot summer period. The study was focused on the research of cubicles with water mattresses and straw bedding for dairy cows. The results of thermal-technical calculations showed that straw belongs to the category of warm floors, the thermal effusivity value of cubicle with straw is b = 173.55 W·s1/2·m−2·K−1; the heat transfer coefficient is U = 0.36 W·m−2·K−1. Water mattress belongs to the category of cold floors with the thermal effusivity value b = 572.46 W·s1/2·m−2·K−1 and the heat transfer coefficient U = 4.504 W·m−2·K−1. On the basis of calculations, the results showed that U was 12.5 higher for water mattresses than for straw, and b was 3.3 times higher for water mattresses than for straw. Based on thermographic measurements under field conditions of dairy farm, it was observed that the surface temperature of the water mattresses after one hour of lying was lower by 4.95 ±1.88 °C in comparison to chopped straw. In practice, suitability of the material structure of water mattresses was verified on the basis of physical properties for summer period.
Basalt Fibre Reinforced Concrete Unprotected to Chemical Attack
Authors: Bajad Mohankumar Namdeorao
Published: June 2020

This paper depends on a test examination on basalt fibres which started from volcanic shakes and were dissolved at high temperatures. These stones were accessible from the world’s profound hull. M30 evaluation of concrete was structured according to is 10262:2009 with basalt fibres. The fibres alongside mineral admixtures were utilized in three distinct extents, that is 0 %, 1 %, 2 %, 3 % by heaviness of cement. The goal was to decide the characteristics of fibre reinforced concrete with various fibre extents. The strength properties, for example, compressive strength, split tensile strength, flexural strength, shear strength and the impact on strength of concrete when it was unprotected to sulphate attack after stipulated extended ages of curing were contemplated and thought about. From the examination, it was discovered that the basalt fibre expanded the strength of concrete notwithstanding when unprotected to sulphate attack bit by bit when compared with consistent concrete. The ideal strength of concrete was accomplished with an enlargement of 2 % basalt fibre.
Questioning the Real Citizen-Centricity of e-Government Development: Digitalization of G2C Services in Selected CEE Countries
Authors: Špaček David , Csótó Mihály , Urs Nicolae
Published: June 2020

This paper presents findings of a pilot research study that focused on a selected area of e-government – digitalization of core government services to citizens (G2C) in selected Central and Eastern European (CEE) countries – namely in the Czech Republic, Hungary, and Romania. Taking into account the literature available to date, it is a first attempt of its kind, even if mainly a qualitative study. The findings clearly indicate that the level of digitalization of the administrative services for citizens is rather low. All three countries are roughly at the same level of electronic government development (with the Czech Republic slightly ahead), despite vastly different strategies and levels of centralization. This could change in the future, after the results of their respective national strategies become visible, and we are also interested in applying our method to other CEE countries, with the clear aim of refining it.

In this study, activated carbon and humic acid powder were fixed by the cross-linking reaction of sodium alginate. Calcium alginate/activated carbon/humic acid (CAH) tri-system porous fibers were prepared by the wet spinning method and freeze-dried for the removal of tetracycline in aqueous solution. Subsequently, the morphology and structure of CAH fibers were measured by scanning electron microscopy (SEM) and the Brunauer-Emmett-Teller (BET) method. The effect of pH, contact time, temperature and other factors on adsorption behavior were analyzed. The Langmuir and Freundlich isotherm models were used to fit tetracycline adsorption equilibrium data. The dynamics data were evaluated by the pseudo-second-order model, the pseudo-second-order model and the intraparticle diffusion model. Thermodynamic study confirmed that the adsorption of tetracycline on CAH fibers was a spontaneous process.

Dear Professor,I am herewith enclosing a research paper entitled “Electrochemical characteristics of BIS 2062 carbon steel under simulated ocean acidification scenario.” authored by Devika KR, and me. The research paper highlights the behavior of carbon steel in acidified natural seawater. Ocean acidification is a burning issue under climate change. Several studies have undertaken to understand the behavior marine organisms and marine environment. No studies have initiated regarding the deterioration of materials due to ocean acidification. Large number of materials were deployed in the ocean with different objectives. These materials are under risk as the ocean acidification continues. We believe this is the first attempt to study the impact of ocean acidification on carbon steel. The study conducted to evaluate the impact of ocean acidification on BIS 2062 boat building steel. The results showed that the carbon steel will deteriorate 2 to 3 times higher when pH was changed from 8.05 to 7.90. The data highlights the immediate need to redesign the marine materials within 1-2 decade. The paper also highlights the possible mechanism of deterioration under different pH scenario.Thanking youSincerelyashrafp

Técnicas de sensoriamento remoto possibilita monitorar e identificar alterações que ocorrem na superfície terrestre, sejam elas ocasionadas por fenômenos naturais ou ação antrópica. O monitoramento dessa dinâmica tornou-se um importante instrumento de pesquisa, pois as transformações ocorridas na cobertura do solo alteram as trocas de radiação entre a superfície a atmosfera. Assim, o objetivo deste trabalho foi analisar os parâmetros biofísicos da superfície em diferentes uso e ocupação em Cuiabá. Foram utilizadas imagens do satélite Landsat 5 durante o ano de 2009. As estimativas dos parâmetros biofísicos foram produzidas a partir de uma camada vetorial com nove pixels sobre cada área. Essas áreas foram classificadas como área de solo exposto, área urbana, vegetação rasteira, área reflorestada, fragmento de floresta urbana e vegetação densa. O índice de vegetação da diferença normalizada (NDVI) apresentou variação de acordo com a cobertura do solo, sendo observado os maiores valores nas áreas com vegetação mais densa. Os maiores valores de albedo foram encontrados nas áreas com pouca ou ausência de vegetação. A Ts foi maior nas áreas com maior grau de antropização e baixa quantidade de vegetação. O Rn foi maior nas áreas com maior densidade vegetal e menor nos pontos com maior antropização. Enfim, os locais com maior quantidade de biomassa vegetal apresentaram maiores valores de NDVI e Rn, além de menores valores de αs e Ts. Effect of Coverage Change on Biophysical Parameters in Cuiabá, Mato Grosso A B S T R A C TRemote sensing techniques make it possible to monitor and identify changes that occur on the earth's surface, whether caused by natural phenomena or anthropic action. Monitoring these dynamics has become an important research tool, since the transformations in the ground cover alter the radiation exchanges between the surface and the atmosphere. Thus, the objective of this study was to analyze the surface biophysical parameters in different use and occupation in Cuiabá. Landsat 5 satellite images were used during 2009. Estimates of biophysical parameters were produced from a vector layer with nine pixels over each area. These areas were classified as exposed soil area, urban area, undergrowth, reforested area, urban forest fragment and dense vegetation. The normalized difference vegetation index (NDVI) varied according to soil cover, with the highest values being observed in areas with denser vegetation. The highest albedo values were found in areas with little or no vegetation. The Ts was higher in the areas with higher degree of anthropization and low amount of vegetation. Rn was higher in areas with higher plant density and lower in areas with greater anthropization. Finally, the sites with the highest amount of plant biomass presented higher NDVI and Rn values, as well as lower αs and Ts values.Keywords: Anthropization, Satellite image, Urbanization.
