Sistema educativo costarricense: ¿Puerta o barrera para el pensamiento crítico?
Authors: Robles Barrantes Andrés Ariel
Published: December 2017

Para intentar comprender las pretensiones de un sistema, en otras palabras, la supuesta visión de un Estado, una de las formas más eficientes y confiables de análisis se materializa en el estudio crítico del sistema educativo establecido en un país, provincia o región. Porque es el sistema educativo quien prepara el futuro de una sociedad. Sin lugar a dudas, los estudios pueden partir de diferentes previstas. Esto quiere decir que un mismo fenómeno se puede abordar con diversos enfoques que al finalizar resulten en conclusiones muy lejanas unas con otras, a pesar de partir de la misma situación o fenómeno de investigación. Es por esto importante aclarar que este ensayo analiza el sistema educativo costarricense desde un punto de vista crítico, partiendo desde una perspectiva de estudio sobre el fortalecimiento de un pensamiento crítico en la población y de esta forma comprender a qué intereses responde el sistema educativo costarricense, entendiendo cuál es su rol dentro del sistema económico neoliberal que se impulsa en Costa Rica.

Authors: Tamayo Gutiérrez Evelin , Sarasty Miranda Oscar , Mosquera Quelal Elizabeth
Published: December 2017

El presente estudio propone una alternativa a la utilización de materiales de petróleo y lignocelulósicos vegetales de origen forestal para la elaboración de empaques secundarios. Se fabricaron cajas con fibras obtenidas del banano y coco, aglutinadas con arrocillo. Primeramente, fueron evaluadas las características del arrocillo de 3 variedades comerciales producidas en Ecuador en cuanto a la cantidad de sólidos hidrosolubles, característica que presentó diferencias significativas, y contenidos de almidón, donde no hubo diferencias estadísticas. Posteriormente, se elaboraron aglomerados de la variedad de arrocillo INIAP 15 y las fibras vegetales en dos diferentes porcentajes de composición para cada tipo de fibra; en dónde se evaluaron características físicas de densidad, tensión y resistencia. Los aglomerados a base de fibra de coco y de banano alcanzaron los valores altos en las tres características físicas evaluadas a diferencia del aglomerado elaborado a base de caña de azúcar, vegetal que finalmente fue descartado como material alternativo en la elaboración de cajas.

Published: December 2017

Bleomycin has progressively been used to treat low-flow vascular malformations in children. No significant systemic side effects have been reported in large series after low doses, but some authors are still concerned about its use. We report a case of a severe acute lung toxicity after a low dose of a second bleomycin intralesional injection in a 5-year-old girl. She had no risk factors and presented a cervical low-flow venous malformation. Twenty-four hours after this second administration, she presented with fever and respiratory distress. A chest radiograph showed bilateral opacities and computerized tomography revealed extensive and diffuse lung ground-glass opacities. The patient started to receive intravenous methylprednisolone, but she experienced progressively increased dyspnea, and montelukast was added. She improved and was discharged from the hospital without oxygen support, with montelukast and prednisolone for tapering doses during months. Five months after onset, the patient is developing well, is active, and walks and talks without dyspnea. A new low-dose computed tomography shows improvement in radiologic findings. This is the second case of pulmonary toxicity observed in a child after bleomycin intralesional administration, and the first reported after the lowest dose of this drug to date (7 mg: 0.28 mg/kg; 10 U: 0.4 U/kg). A delay in the diagnosis and treatment of this complication can be fatal. Any physician who treats these patients must be alert and consider this complication in children with respiratory symptoms after bleomycin sclerotherapy. Early detection of pulmonary toxicity would allow prompt therapy and could avoid pulmonary damage.

Authors: Hidayat Thomas , Noegroho Tegoeh , Wagiyo Karsono
Published: December 2017

Ikan cakalang (Katsuwonus pelamis Linnaeus, 1758) merupakan salah satu sumberdaya ikan pelagis besar yang mempunyai nilai ekonomis penting. Informasi mengenai struktur ukuran dan beberapa parameter populasinya masih sangat terbatas khususnya di perairan Indonesia timur. Penelitian ini dilakukan di Morotai, Biak dan Jayapura dari Januari sampai Desember 2013. Tujuan penelitian ini adalah untuk menganalisis ukuran ikan yang tertangkap dan menganalisis parameter populasi meliputi laju pertumbuhan, mortalitas dan tingkat eksploitasi. Estimasi parameter pertumbuhan, mortalitas dan laju eksploitasi dihitung menggunakan program FiSAT (FAO-ICLARM Stock Assessement Tools). Ukuran ikan cakalang hasil tangkapan pancing tonda dan pancing ulur berkisar antara 15 – 94 cmFL (Fork Length), dengan modus antara 40-45 cmFL. Ukuran pertama kali tertangkap sebesar 40,1 cmFL dan kebanyakan adalah ukuran ikan yang sedang memijah. Hasil analisis menggunakan FiSAT II diperoleh laju pertumbuhan (K) sebesar 0,41/tahun, panjang asimptotik (L) 101,85 cmFL. Laju kematian alami (M) 0,6 / tahun, laju kematian karena penangkapan (F) 0,62 /tahun dan laju mortalitas total (Z) 1,22 /tahun. Tingkat eksploitasi ikan cakalang hampir fully exploited (E= 0,46). Disarankan tidak perlu ada penambahan upaya penangkapan atau status quo untuk menjaga agar sumberdaya ikan cakalang tetap terjaga kelestariannya. Skipjack tuna (Katsuwonus pelamis Linnaeus, 1758) is one of the large pelagic fish resources which have high economic value. Information on the size structure and population parameters is still limited especially in the waters of eastern Indonesia. The Research was conducted from January to December 2013 at Morotai, Biak and Jayapura. The aim of this study was to analyze the size of the fish caught and some of population parameters such as the growth rate, mortality rates, and exploitation rate. Estimated of growth parameters, mortality and exploitation rate using the program FiSAT (FAO-ICLARM Stock Assessement Tools). The size of skipjack tuna caught by troll line and handline in between 15-94 cmFL, with a mode of 40-45 cmFL. The Length at first capture was 40.1 cmFL, most of them had condition of spawning. By using program FiSAT II analysis resulted that growth rate (K) of skipjack tuna was 0.41/year, with length asimptotik (L) reaches 101.85 cmFL. The natural mortality rate (M) was 0.6 / year. The fishing mortality rate (F) was 0.62 / year and total mortality rate (Z) was 1.22 / year. The exploitation rate of skipjack tuna was nearly fully exploited (E = 0.46). It was recommended the exploitation rate of this fish should be no additional effort (status quo) to keep sustainability of the skipjack tuna resource.

Kanibalisme yang tinggi adalah salah satu permasalahan utama dalam budidaya lobster. Penggunaan selter individu pada budidaya pendederan lobster dimaksudkan untuk meniadakan kontak langsung antar lobster dalam media budidaya. Tujuan penelitian ini adalah untuk menganalisis kualitas air dan pengaruh penggunaan selter individu terhadap kinerja produksi pendederan lobster pasir Panulirus homarus dengan sistem resirkulasi. Lobster berukuran 51,29 ± 7,26 g/ekor dipelihara selama 60 hari dengan pemberian pakan 3%-4% sebanyak satu kali per hari. Penelitian dilakukan dengan empat perlakuan dan dua ulangan. Jenis perlakuan yang digunakan, yaitu selter pipa PVC sebagai kontrol (K), selter individu persegi (SI n), selter individu segitiga (SI ), dan selter individu tabung (SI l). Hasil penelitian menunjukkan bahwa kualitas air budidaya menggunakan sistem resirkulasi masih memenuhi syarat untuk budidaya lobster. Penggunaan selter individu berpengaruh positif terhadap respons sintasan, tetapi berpengaruh negatif terhadap pertumbuhan lobster.High cannibalism was an important issue in lobster rearing. The use of individual shelter in lobster rearing was intended to eliminate a direct contact between lobsters in a rearing media. The purpose of this study was to analyze water quality and the effect of individual shelter on the growth response of spiny lobster (Panulirus homarus) juvenile reared in an aquaculture media equipped with a recirculation system. Lobsters with an average size of 51.29 ± 7.26 g were reared for 60 days and fed with trash fish of 3%-4% of the biomass daily. This study used four treatments with two replications. The treatments consisted of a PVC pipe shelter as control (K), individual square shelter (SI n), individual triangle shelter(SI ), and individual tube shelter (SI l).The results of the study showed that the water quality in the aquaculture media was still within the suitable range for lobster rearing. The use of individual shelter had positive effects on the survival rate but had negative effects on the growth of spiny lobster juvenile.

Analiza przyczyn występowania różnic w podejściu do napływu imigrantów w państwach członkowskich Unii Europejskiej
Authors: Tendera-Właszczuk Helena
Published: December 2017

The influx of illegal immigration to the European Union has grown rapidly over the past few years. Member States’ official stances and policies differ considerably as to whether to accept or reject refugees and illegal immigrants. Using a quantitative analysis, the article examines the causes of the different approaches to immigration to the EU Member States. It provides a general overview of the demographic forecasts until 2080 and suggests two new indicators to explain the acceptance (or rejection) of foreigners. It follows from the considerations that quantitative indicators are insufficient in determining whether to have a positive or negative position with regard to accepting immigrants to EU Member States.

Punch grafts to treat lower limb intractable sores
Authors: FERNANDES JÚLIO WILSON , AKAMINE RAFAEL SONODA , CASAGRANDE EDUARDO CASTILHO
Published: December 2017

ABSTRACT Lower limb recurrent ulcers, usually caused by prolonged decubitus, trauma, diabetes or burns, may not heal with conventional clinical or surgical treatment. Frequently, laminated skin grafts do not integrate with the recipient layer, and the only alternatives are neighbor microsurgical flaps. These have higher morbidity and create secondary defects, to be corrected with skin grafts, when fasciocutaneous or miocutaneous segments are removed for the treatment of the primary defect. We describe the non-conventional use of punch grafts in the treatment of lower limb ulcers, when conventional skin laminated graft failed, without the use of flaps. Since this is a very successful technique, its use should be considered as a valuable alternative for the treatment of recurrent lower limb ulcers. It is a simple and easy-learned technique that may be used by different surgeons, even in remote places without correct specialized hospital facilities.

Published: December 2017

Abstract The objective of this study was to determine of oral and oropharynx cancer mortality rate and the results were analyzed by applying the Spatial Analysis of Empirical Bayesian Model. To this end, we used the information contained in the International Classification of Diseases (ICD-10), Chapter II, Category C00 to C14 and Brazilian Mortality Information System (SIM) of Minas Gerais State. Descriptive statistics were observed and the gross rate of mortality was calculated for each municipality. Then Empirical Bayesian estimators were applied. The results showed that, in 2012, in the state of Minas Gerais, were registered 769 deaths of patients with cancer of oral and oropharynx, with 607 (78.96%) men and 162 (21.04%) women. There was a wide variation in spatial distribution of crude mortality rate and were identified agglomeration in the South, Central and North more accurately by Bayesian Estimator Global and Local Model. Through Bayesian models was possible to map the spatial clustering of deaths from oral cancer more accurately, and with the application of the method of spatial epidemiology, it was possible to obtain more accurate results and provide subsidies to reduce the number of deaths from this type of cancer.

ABSTRACT Objective: to develop the operational and conceptual definitions of the defining characteristics and related factors of the nursing diagnosis Acute Pain (00132) for nonverbal critically ill patients. Method: integrative literature review in the databases/libraries: Medical Literature Analysis and Retrieval System Online (MEDLINE via Pubmed), Cochrane Library, The Cumulative Index to Nursing and Allied Health Literature (CINAHL) and Latin American & Caribbean Health Sciences Literature (LILACS). Results: 799 results were found in the literature, of which 80 studies were selected for full text reading and 16 were used in the elaboration of definitions for the 17 defining characteristics and three related factors of the nursing diagnosis. The gray literature, ie, thesis, dissertations, books, guidelines and dictionary was also explored to ensure the robustness needed to clarify the topics not covered by the studies. Conclusion: the definitions aim to facilitate the identification of the nursing diagnosis for nonverbal critically ill patients and to support future teaching and research on the nursing diagnosis of Acute Pain (00132).
THE CHALLENGES OF THE ANTHROPOCENE: FROM INTERNATIONAL ENVIRONMENTAL POLITICS TO GLOBAL GOVERNANCE
Authors: FRANCHINI MATÍAS , VIOLA EDUARDO , BARROS-PLATIAU ANA FLÁVIA
Published: December 2017

Abstract : This article proposes a reflection on the challenges of global environmental policy in the Anthropocene. Firstly, the inconsistency between the institutions of international environmental policy and the progressive degradation of the planetary boundaries is highlighted. Secondly, it is stated that, since the transition to Anthropocene requires the conscious construction of a new space of safe operation for humanity, it is necessary to radically modify the institutional structure of cooperation, based on international regimes: the transition from environmental politics to global governance. The fundamental milestone of this path is the overcoming of the international system of conservative hegemony, that is, the abandonment of the sovereignist tendencies - egotistical and short-term - on the part of its actors, particularly the great powers. Finally, a series of premises for the governance of the Anthropocene is proposed from the point of view of International Relations, with the post-sovereign transition as the main pillar.

Published: December 2017

ABSTRACT The purpose of this catalogue was to combine the available data from publications, theses, databases, and herbarium specimens from around 120 Herbaria, and colections sampled in Brazilian vegetation during the last 15 years to produce the most complete list, as possible as, of Cyperaceae species for Brazil. We catalogued ca. 1,700 names for 678 species in 42 genera occurring in Brazil. These values represent ca. 15 percent of the species and 40 percent of the genera found in the world. Both subfamilies of Cyperaceae are found in Brazil with Cyperoideae being the most diverse at both generic and specific levels. Although lower species were recorded for the tribes Cryptangieae, Sclerieae, and Trilepideae, these tribes represent a much higher percentage of the world's totals for genera and species. The most diverse genera are Rhynchospora (157 spp.), Cyperus (101 spp.), Scleria (82 spp.) and Eleocharis (69 spp.). Fifteen genera have one species in Brazil, although five of them are monospecific. The most species-rich regions in Brazil are the North and Southeast. There are no genera endemic to Brazil. There are, however, around 200 endemic species, of which 40 are in the genus Rhynchospora. Taxonomic and nomenclatural problems found are pointed under the species. For each catalogued species, the principal synonyms, bibliographic references, distribution within Brazil's five regions, vegetation type, and citation of selected material examined are provided.

Published: December 2017

Abstract Even though many new combinations have been proposed for the genera Anathallis Barb.Rodr. and Specklinia Lindl., since their re-establishment in 2001, several Brazilian species bearing the characteristics of these genera were never transferred from Pleurothallis R.Br. sensu lato. In this work 17 Brazilian species formerly attributed to Pleurothallis are transferred to Anathallis (16 species) and Specklinia (one species). Also, several superfluous names created from double new combinations in the genera Anathallis and Specklinia are pointed out.

“Hvad de skrifva i tidningare i Stockholm” Prensa y opinión pública en Suecia ante la emigración temprana a América (1861-1865)
Authors: Gila Oscar Álvarez
Published: December 2017

Resumen Este artículo analiza el modo en el que la prensa sueca presentó la emigración a América en el periodo comprendido entre 1861 y 1865, es decir, en los años de la Guerra Civil en Estados Unidos. Este país comenzaba a ser, ya por entonces, el principal receptor de emigrantes suecos, en un proceso que se alargaría hasta la tercera década del siglo XX. Basándonos en un corpus de casi un millar de referencias periodísticas, estudiamos el modo en el que se conformó la temprana opinión pública ante la emigración. A diferencia de lo que caracterizaría el primer tercio del siglo XX, a mediados del XIX los periódicos suecos ofrecían una visión equidistante, y hasta cierto punto positiva, de la emigración.
Effect of nutri-priming on germination indices and physiological characteristics of stevia seedling under salinity stress
Authors: Shahverdi Mehdi Aghighi , Omidi Heshmat , Tabatabaei Seyed Jalal
Published: December 2017

Abstract: Poor germination and low seedling growth of stevia (Stevia rebuadiana Bertoni) are common problems in the cultivation of the plant. On the other hand, salinity is one of the abiotic environmental stresses that reduce the performance of the product. The objective in this study was to assess the effect of nutri-priming with selenium (Se), iron (Fe) and boron (B) on stevia seed germination indices and physiological characteristics in sodium chloride (NaCl) salinity condition (0, 30, 60 and 90 mM). Results indicated that the effect of salinity in nutri-priming were significant on germination percentage, germination rate, germination uniformity, germination value, seedling length, seedling vigor index, total chlorophyll, free proline content and enzymatic activity of catalase (CAT) and superoxide dismutase (SOD). Salinity stress decreased the percentage and rate of germination and seed vigor, however, nutri-priming reduces the adverse effects of salinity stress. Salinity also reduced the amount of chlorophyll content, in spite of all that this decrease was very low in terms of nutri-priming with Se, Se+Fe and Se+Fe+B in high salinity level (90 mM). Salinity stress increased proline content and antioxidant enzyme activities of CAT and SOD, that nutri-priming especially with the Se more increased. The finding of this study leads to the conclusion that nutri-priming with nutrients, especially Se and Fe increased the antioxidant capacity of the plant to improve germination and seedling growth of stevia under salinity stress.

Abstract: This study evaluated the physiological potential of soybean seeds harvested during two seasons, on different maturation stages and subjected to different drying temperatures. The seeds were harvested at the maturations stages R7, R7 + 2, R7 + 3, R7 + 5, R7 + 6, R7 + 7, R7 + 10 and R7 + 12 days (55, 50, 45, 40, 35, 30, 25, and 20% of moisture content). For each maturation stage, seeds were divided into three samples: one sample was used to directly evaluate the physiological potential, and the others were dried at 40 °C and 50 °C, until reaching the moisture content of 11.5%. The physiological potential was evaluated through germination test, first germination count of germination, accelerated aging, modified cold, electrical conductivity and seedling emergence. The maximum physiological potential of seeds is achieved at the moisture content of 55%, the point that the dry matter is maximum. The seeds became tolerant to artificial drying approximately at the stage R7 + 7 days (30% of moisture content). Germination and vigor of the soybean seeds reduce as the drying temperature is increased from 40 °C to 50 °C, and this effect is enhanced when the seeds show moisture contents above 30%.

Abstract: The aim of this study was to evaluate the physiological quality of soybean seeds submitted or not to dynamic cooling, and kept in cold storage (CS) and non-cold storage (NCS). A soybean seeds lot, variety M7639RR, was divided into two parts, and each one was subdivided into three parts that were subjected to one of these cooling procedure: seeds without cooling (SWC), dynamic cooling at 17 °C (SC17), and dynamic cooling at 13 °C (SC13). Seeds were kept in CS and NCS at 20 °C. Samples were collected at six times (0, 45, 90, 135, 180 and 225 days), and then submitted to germination, tetrazolium, accelerated aging and seedling emergence tests. Dynamic artificial cooling at 13 °C followed by maintenance at 20 °C ensured the preservation of physiological quality of soybean seeds for up to 225 days. The vigor of the soybean seeds subjected to dynamic cooling at 13 °C was better preserved than that of the non-cooled or of the cooled at 17 °C ones and kept in NCS for 225 days. CS at 20 °C contributed to the preservation of the physiological quality of the soybean seeds, regardless of whether or not they were submitted to the dynamic procedure.

ABSTRACT: The Faina Greenstone Belt is located in the southern sector of the Goiás Archean Block and has been investigated since the 18th century because of its gold deposits. Recent studies have revealed the polymetallic potential of the belt, which is indicated by anomalous levels of Ag, Cu, Fe and Co in addition to Mn, Ba, Li, Ni, Cr and Zn. This study was developed based on a detailed analysis of two selected target sites, Cascavel and Tinteiro, and multiple data sets, such as airborne geophysics, geochemistry and geological information. These datasets were used to create a final prospectivity map using the fuzzy logic technique. The gold mineralization of Cascavel target is inserted in an orogenic system and occurs in two overlapping quartz veins systems, called Mestre-Cascavel and Cuca, embedded in quartzite with an average thickness 50 cm and guidance N45º-60ºW/25ºSW with free coarse gold in grains 2-3 mm to 3 cm. The prospectivity map created for this prospect generated four first-order favorable areas for mineralization and new medium-favorability foci. The Tinteiro area, derived from studies conducted by Orinoco do Brasil Mineração Ltda., shows polymetallic mineralization associated with an iron oxide-copper-gold ore deposit (IOCG) system posterior to Cascavel target mineralization. Its prospectivity map generated 19 new target sites with the potential for Au, Cu and Ag mineralization, suggesting new directions for future prospecting programs.

Abstract: The objective of this work was to predict the genetic gains with selection of superior individuals within papaya (Carica papaya) progenies using the REML/Blup analysis. Thirty-six S2 progenies, originated from the Calimosa and Tainung 1 hybrids, and two commercial control checks were evaluated in a randomized complete block design, with four replicates. The following traits were evaluated: heights of plants and first fruit; stem diameter at 12 and 18 months; number of days required for fruiting; number, mass, and average mass of commercial fruit; and number and mass of carpelloid and pentandric fruit. The magnitudes of the genetic parameters indicated that the variability present in most of the characters allows greater genetic gain if the selection is made at the progeny level, and not in individual plants. For selection among progenies, PROT-268, PROT-74, PROT-55, and PROT-22 were the most promising, with the greatest genetic gain for the studied characters. In the selection among and within progenies, the prediction of the gains is higher for the increase in the expression of the number of commercial fruit and for the decrease in the expression of pentandric fruit.

Abstract: The objective of this work was to characterize the chemical composition of olive (Olea europaea) oils produced in Southern of Brazil and correlate it with oxidative stability. Olive oils from the Arbequina, Coratina, Frantoio and Koroneiki cultivars were evaluated. A completely randomized experimental design was used, in a uniform arrangement, with three replicates. Acidity value, peroxide index, specific absorption, tocopherol content, phenolic compound content, carotenoid content, chlorophyll content, fatty acid profile, and oxidative stability were determined. The oils from the Coratina and Frantoio cultivars were classified as extra virgin-oils. The olive oil from the Coratina cultivar showed the highest levels of pigments, followed by the oil from Koroneiki. The oil from the Coratina cultivar also presents higher contents of phenolic compounds (1,725.5 mg kg-1) and tocopherols (437.8 mg kg-1). The major fatty acid in all samples is oleic acid.

Abstract: The objective of this work was to determine a method to simulate water stress in vitro to select drought-tolerant banana (Musa sp.) genotypes. The BRS Tropical and Prata Anã cultivars were grown in vitro in an MS liquid medium containing sucrose and benzylaminopurine (BAP), supplemented with different concentrations of polyethylene glycol (PEG) or sorbitol. The yield stability index of dry matter was evaluated. Cultivation for 30 days in a medium containing 15 g L-1 PEG or 36.4 g L-1 sorbitol is appropriate to simulate water stress in vitro.

Most of the current design codes of practice allow the use of reinforced-concrete moment frames with wide beams in regions of high seismicity. These design codes prescribe beam-width limitations and special reinforcement details to minimise the lag in the formation of full-width plastic hinges. However, due to insufficient experimental and analytical studies, empirical design formulas for beam-width limitation, with remarkable differences, have been implemented in these codes. In this paper, an effective beam-width model of exterior wide beam–column connections is analytically developed using the equivalent-frame model representation, where the effect of torsion of transverse beams and flexure around the joint core is considered. The validity of the model is verified using flexural strength predictions of previously published tests in the literature, covering a wide range of design parameters. Combining the proposed effective beam-width model and the rational, analytical approach, a formula is presented for determining the beam-width limitation of exterior wide beam–column connections. For convenient application in practical design, the proposed beam-width limitations of both exterior (derived in this paper) and interior connections (previously derived by the authors) are further simplified, and the relevant design curves and charts are presented.

Objetivo: analisar os efeitos do consumo de chá verde associado ao exercício físico sobre a composição corporal de pessoas obesas. Materiais e método: o estudo trata-se de uma revisão sistemática de literatura. As buscas foram feitas nas bases de dados Lilacs, Scielo e PubMed, utilizando os descritores: obesidade, chá verde, Camellia Sinensis, exercício. Os artigos utilizados foram publicados entre os anos de 2003 a 2015. Resultados: uma ferramenta recentemente utilizada para o controle do peso é o chá verde, considerado um alimento funcional; é a segunda bebida mais consumida no mundo. Evidências mostram seu efeito termogênico com aumento do gasto energético e promoção da oxidação de gorduras. O consumo de chá verde se mostrou efetivo na diminuição de massa corporal, especialmente na forma de gordura, porém o consumo do chá aliado à prática de exercício se mostra mais eficaz para a redução de peso. Ressalta-se ainda que os hábitos alimentares saudáveis devem ser incentivados para obter o máximo dos benefícios dessa planta. Considerações finais: é necessária a investigação mais aprofundada para determinar as doses e formas de administração seguras do chá verde, bem como os mecanismos de ação e da biodisponibilidade dos compostos ativos, pois se trata de um alimento de baixo custo e que pode ser utilizado no manejo nutricional de doenças crônicas como a obesidade, colaborando assim, para a qualidade de vida e saúde da população.
