A CONCESS O DE SERVI OS TURíSTICOS EM PARQUES NACIONAIS SOB A PERSPECTIVA JURíDICA DAS PARCERIAS PúBLICO-PRIVADAS
Bruno Pereira Bedim,Adriano Pereira da Silva
Revista Brasileira de Ecoturismo , 2011,
Abstract: Este trabalho tem como objetivo analisar a concess o de servi os turísticos em Parques Nacionais sob a forma de parcerias público-privadas, discutindo o crescimento paulatino desse tipo de parceria como conseqüência da atual conjuntura política, social, econ mica e até mesmo jurídica da sociedade brasileira. Para tanto, procedeu-se à delimita o conceitual e legal do que seja Parceria Público-Privada (PPP), evidenciando essa nova forma de gerir a coisa pública como conseqüência dos imperativos de mercado e, também, como corolário da ineficiência do Estado no sentido de manter o monopólio da gest o dos bens e dos servi os públicos nos dias atuais. Empreendida esta primeira análise, procedeu-se ent o à abordagem das parcerias público-privadas especificamente no ambito dos Parques Nacionais, apresentando exemplos brasileiros de implanta o de tais parcerias. Por fim, realizou-se uma aprecia o crítica sobre o atual contexto dos Parques Nacionais, apresentando sugest es de medidas que possam contribuir para melhorar as suas condi es de infraestrutura e servi os disponíveis aos visitantes, de modo que os Parques alcancem, o máximo possível, os fins que lhes foram conferidos pela legisla o pertinente. Palavras-chave: Parceria Público-Privada; Parques Nacionais; Turismo.
ATIVIDADE ECOTURíSTICA E DINAMIZA O DA ECONOMIA EM CACHOEIRA GRANDE
Bruno Ricardo Monteiro Alcantara,Karla Sousa Pereira
Revista Brasileira de Ecoturismo , 2011,
Abstract: O município de Cachoeira Grande está localizado na Mesorregi o Norte Maranhense, possuindo uma popula o predominantemente rural. Estando assentado na Forma o geológica Itapecuru, o município de Cachoeira Grande apresenta solos com limita es para o desenvolvimento de práticas agrícolas, o que implica em reflexos sociais e econ micos para a popula o, já que a dinamica econ mica da regi o ocorre em fun o dessas atividades. A agricultura se desenvolveu historicamente na regi o porque esteve associada ao cultivo de espécies altamente eficiente no aproveitamento dos nutrientes (mandioca, feij o e melancia) por meio da associa o com microorganismos (fungos VAM e bactérias diazotróficas) e porque foi mantida basicamente pela matéria organica produzida pela própria vegeta o a partir da ciclagem de nutrientes. Essas práticas que antes se mostravam eficientes do ponto de vista ambiental e de sustenta o de produtividade vem se mostrando problemática diante de um aumento na densidade populacional e de uma redu o das áreas cultiváveis. Neste sentido, a dinamica econ mica do município de Cachoeira Grande, evidenciando diversos problemas ambientais especialmente nas áreas de matas ciliares, demanda diversas atividades mitigadoras que v o desde a educa o ambiental até a oferta de atividades que sejam mais racionais no uso dos recursos, unindo a gera o de renda com a manuten o dos frágeis ecossistemas que est o assentados sobre a base física do território de Cachoeira Grande. Apesar dos solos de Cachoeira Grande serem quimicamente pobres e altamente susceptíveis aos processos erosivos e da vegeta o estar imensamente degradada em fun o da agricultura, o município apresenta paisagens naturais exuberantes que podem ser utilizadas racionalmente pelo turismo, especialmente pelo ecoturismo. Os LATOSSOLOS formados por sedimentos oriundos de arenitos abrigam diversas paleodunas entremeadas de corpos de riachos e rios (a exemplo do Pirangi) de águas límpidas e extremamente frias. Características similares têm atraído em outros municípios visinhos enorme fluxo de turistas, dinamizando suas economias. Apesar da proximidade, Cachoeira Grande é pouco conhecida entre os habitantes de S o Luís. Tal situa o pode ser exemplificada pela presen a constante de visitantes no município de Morros, apesar da pequena distancia entre um município e outro e de possuir lugares com uma maior qualidade ambiental. Mas a aplica o do Ecoturismo está condicionado a diversos fatores, principalmente na implanta o de uma gest o voltada para o ecoturismo, que priorizasse o preparo dos morador
PINE WOOD MODIFICATION BY HEAT TREATMENT IN AIR
Bruno Esteves,Idalina Domingos,Helena Pereira
BioResources , 2008,
Abstract: Maritime pine (Pinus pinaster) wood has low dimensional stability and durability. Heat treatment was made in an oven using hot air during 2 to 24 h and at 170-200 oC. A comparison was made against steam heat treatment. The equilibrium moisture content and the dimensional stability (ASE) in radial and tangential directions were evaluated at 35%, 65%, and 85% relative humidity. MOE, bending strength and wettability were also determined. At the same mass loss, improvements of equilibrium moisture content and dimensional stability were higher for oven heat treatment, but the same was true for mechanical strength degradation. A 50% decrease in hemicellulose content led to a similar decrease in bending strength.
WOOD MODIFICATION BY HEAT TREATMENT: A REVIEW
Bruno M. Esteves,Helena M. Pereira
BioResources , 2009,
Abstract: Wood heat treatment has increased significantly in the last few years and is still growing as an industrial process to improve some wood properties. The first studies on heat treatment investigated mainly equilibrium mois-ture, dimensional stability, durability and mechanical properties. Mass loss, wettability, wood color, and chemical transformations have been subsequently extensively studied, while recent works focus on quality control, modeling, and study the reasons for the improvements. This review explains the recent interest on the heat treatment of wood and synthesizes the major publications on this subject on wood properties, chemical changes, wood uses, and quality control.
How CAGE, RAPS4QF and AUDIT can help practitioners for patients admitted with acute alcohol intoxication in emergency departments?
Georges Brousse,Bruno Pereira,Ingrid De Chazeron
Frontiers in Psychiatry , 2014, DOI: 10.3389/fpsyt.2014.00072
Abstract: Aims: To help clinicians to identify the severity of Alcohol Use Disorders (AUD) from optimal thresholds found for recommended scales. Especially, taking account of the high prevalence of alcohol dependence among patients admitted to the Emergency Department (ED) for acute alcohol intoxication (AAI), we propose to define thresholds of severity of dependence based on the AUDIT score. Methods: All patients admitted to the ED with AAI (blood alcohol level >0.8g/L), in a two-month period, were assessed using the CAGE, RAPS-QF and AUDIT, with the alcohol dependence/abuse section of the Mini International Neuropsychiatric Interview (MINI) used as the gold standard. To explore the relation between the AUDIT and the MINI the sum of the positive items on the MINI (dependence) as a quantitative variable and as an ordinal parameter were analyzed. From the threshold score (TS) found for each scale we proposed intervals of severity of Alcohol Use Disorders (AUDs). Results: The mean age of the sample (122 males, 42 females) was 46 years. Approximately 12 % of the patients were identified with alcohol abuse and 78 % with dependence (DSM-IV). Cut points were determined for the AUDIT in order to distinguish mild and moderate dependence from severe dependence. A strategy of intervention based on levels of severity of AUD was proposed. Conclusion: Different thresholds proposed for the CAGE, RAPS4-QF and AUDIT could be used to guide the choice of intervention for a patient: brief intervention, brief negotiation interviewing or longer more intensive motivational intervention.

American Journal of Climate Change (AJCC) , 2018, DOI: 10.4236/ajcc.2018.73023
Abstract: The intense and extreme rains in southeastern Brazil are spatially and temporally dynamic, corroborating their substantial complexity regarding understanding and associations. Therefore, the present study aimed at determining threshold values for events of intense and extreme rainfall in the region of São Carlos/SP using a climatic index, as well as temporal and spatial observations. The RClimdex script, Rnn index, and the detection of outliers were employed in order to mark and establish intense and extreme rainfall thresholds for the region. Values of 10 mm and 20 mm of rain were considered typical and of greater recurrence, and their incidence over a period of 24 hours did not necessarily denote intense events. In turn, values of 35, 46, and 60 mm indicate pluviometric rates that impact on significant disasters, as verified in the IPMET/UNESP natural disasters database. It is important to emphasize that values below 60 mm of daily rainfall may also indicate disaster contexts. However, they do not exclude the necessity to verify the intensity, duration, and frequency of intense rain events, and can delineate thresholds for territorial management organizations in their planning.

American Journal of Plant Sciences (AJPS) , 2018, DOI: 10.4236/ajps.2018.94062
Abstract: Proteomics techniques were used to study the molecular mechanisms involved in the defense of tomato against late blight (Phytophthora infestans). Proteins were extracted from resistant access BGH-2127 and susceptible cultivar Santa Clara. Leaves of the inoculated and non-inoculated (control) genotypes were collected at 0, 2, and 48 h after inoculation and analyzed by two-dimensional electrophoresis (2-DE), followed by identification with mass spectrometry (MALDI TOF-TOF). A total of 56 differentially abundant proteins were identified, of which 39 were resistant genotypes and 17 were susceptible. These proteins were categorized into functional groups of energy and metabolism, photosynthesis, stress and defense, transcription, other proteins, and as un-characterized ones. For access BGH-2127, oxidative stress proteins (2-cis peroxiedoxin BAS1 and 2-cis peroxiredoxin) and thaumatin-like protein showed increase in the relative abundance at 0 and 48 h of inoculation, respectively, and were therefore considered important for the defense mechanism of this genotype. The expression standards evaluated by real-time PCR differed from the results of the proteomic analysis. The protein-protein interaction networks provided important information on the cellular activities involved in the resistance of BGH-2127 late blight.

Fabiano de Andrade Ferreira, Bruno Pereira Freire, Juliana Taís Andreghetto de Souza, William Renzo Cortez-Vega, Carlos Prentice
Food and Nutrition Sciences (FNS) , 2013, DOI: 10.4236/fns.2013.45075
Abstract:

Proteins recovered were obtained from Whitemouth Croaker (Micropogonias furnieri) byproducts and their physico-chemical and functional properties were evaluated. The proximate composition, presented 8.64% ± 0.10% of moisture, 85.33% ± 0.12% of protein, 2.69% ± 0.09% of ashes and 2.16% ± 0.12% of lipids, in dry basis. The highest solubility was obtained in pH 11 (93.24%), the maximum water holding capacity was presented at pH 11 (25.71 mL H2O/gprotein), the oil holding capacity was 13.71 mL/gprotein and the digestibility in vitro was 91.32% ± 0.15%. The electro-phoretic profile was observed typical of the myofibrillar proteins, with the appearance of the heavy chain of myosin (220 kDa) and actin (50 kDa). The results show that the products of low commercial value of fish that are usually used for the production of animal feed or simply discarded, contributing to environmental pollution, may be used to produce products with a greater added value.

Microscopy Research (MR) , 2017, DOI: 10.4236/mr.2017.51001
Abstract: The fish Prochilodus lineatus (Characiformes, Prochilodontidae), in addition to being a good bioindicator, is also of economic and ecological importance with a broad distribution in the neotropics. Ecotoxicology examines the interaction between environmental chemistry and biota; and in this study we assess alterations of bile and glycogen levels in the fish liver, organ responsible for detoxification, biotransformation and storing nutrients, such as glycogen, and for secreting bile. Fish were separated in three groups to examine the damage caused by the exposure to waters from Lago Azul-Rio Claro-SP and containing diluted biodegradable detergents in comparison to a control group (chlorinated water from an artesian well of UNESP-Campus Rio Claro). A histological analysis was performed on HE and PAS stained sections. The identification of structural changes and the assessment of the area occupied by bile and glycogen were carried out with the software ImageJ, showing that the liver was affected morphologically (cell vacuolization, peripherals nuclei, for example) and problems in bile release and production and storage of glycogen.
