O ano 2019 foi declarado ANO INTERNACIONAL DA TÁBOA PERIÓDICA polas Nacións Unidas, para conmemorar os 150 anos da publicación por Dimitri Mendeleev da súa táboa periódica e por se celebrar o centenario da creación da IUPAC; pero non se escoita falar nada polo noso País de tal acontecemento. Ao noso grupo de investigación educativa CienciaNOSA pareceunos oportuno facer unha profunda reflexión, no noso XXXI congreso de ENCIGA, sobre tan importante e transcendente acontecemento. Pretendiamos facer unha chamada en alta voz para resaltar este transcendental feito e reclamar das nosas autoridades académicas e políticas a súa implicación neste relevante acto con actuacións específicas. Desde ENCIGA, o noso grupo de investigación queriámonos poñer diante do carro para tirar del e facer deste ano un ano frutífero para a nosa ciencia.
BUSCADORES DE ELEMENTOS, CONSTRUCTORES DO SISTEMA PERIÓDICO

Published: January 2022

No ano 1869, hai cento cincuenta anos, Dimitri Mendeleiev publicou unha táboa periódica dos elementos quı́micos que, desenvolta e refinada, é, quizá, unha das leis cientı́ficas que exerceu máis influencia. A táboa, que ocupa un lugar preeminente no estudo da quı́mica, é unha das ideas máis frutı́feras da ciencia moderna, quizá comparable coa teorı́a de evolución de Darwin ou coa teorı́a da tectónica global. A diferenza da mecánica de Newton, non foi desmentida pola fı́sica moderna e, a pesar dos profundos cambios habidos na ciencia durante o séculos XX e XXI (pénsese na teorı́a da relatividade e na mecánica cuántica), a estrutura básica da táboa non sufriu unha transformación radical, senón que se adaptou e madurou. Sinalemos algúns sabios que interviñeron na súa construción, sen esquecernos dos que, previamente, buscaron e acharon os distintos elementos quı́micos.
LEGADO ESPAÑOL Á TÁBOA PERIÓDICA

Published: January 2022

A táboa periódica é instrumento de extraordinaria importancia xa que dota á ciencia en xeral e á quı́mica en particular dunha linguaxe común. España contribuı́u de forma significativa á construción da táboa periódica co descubrimento de tres elementos quı́micos: O platino descuberto polo mariño e matemático sevillano, Antonio de Ulloa, o vanadio illado polos irmáns logroñeses Juan José e Fausto Delhuyar no Real Seminario de Vergara e finalmente, o vanadio por Andrés Manuel do Rı́o, un madrileño que viviu e morreu en México.
O SISTEMA PERIÓDICO DENDE A PERSPECTIVA DUN QUÍMICO ORGÁNICO
Authors: Peña Diego
Published: January 2022

A táboa periódica é unha das construcións humanas mais abraiantes que existen. Semella sinxela, formada ata o momento por 118 pezas que son os elementos químicos coñecidos, pero distribuídos dunha maneira especialmente harmoniosa que codifica unha información extremadamente valiosa. Sen dúbida, fascinante pola súa lóxica e orde. Pero ademais, o sistema periódico aglutina o coñecemento xerado por milleiros de persoas curiosas que contribuíron durante séculos a entender (as veces incluso a dominar) o mundo qu e nos rodea. En 2019 homenaxeamos especialmente a un deses pioneiros, o gran Dmitri Mendeleev, quen coa publicación da súa proposta de táboa periódica hai 150 anos cambiou a historia da química. Pero valoremos tamén as achegas doutros pioneiros, máis ou menos anónimos, dese inxente traballo colaborativo que é o sistema periódico. Porque facendo unha similitude co que din que dixo outro ilustre pioneiro da ciencia, Isaac Newton, atreveríame a dicir que Mendeleev logrou ollar mais aló porque estaba subido nos ombreiros de xigantes.
TÁBOAS PERIÓDICAS PARA TODO TEMPO E LUGAR (2ª EDICIÓN)

Published: January 2022

No ano 2009, publicouse nesta revista un artigo1 no que se recollía o resultado dunha actividade levada a cabo no curso 2007/08 por alumnado de ESO do IES de Sar (Santiago), co gallo do centenario do pasamento de Mendeleiev. A actividade consistíu na búsqueda na rede das diferentes propostas que tiñan a clasificación periódica dos elementos químicos como centro de interese. Dez anos despois, durante o presente curso (2018/19) realizouse unha actividade semellante cun grupo de alumnas e alumnos de 4º ESO e de 1º BAC, aproveitando a celebración dos 150 anos da publicación da primeira Táboa Periódica dos elementos químicos. De igual maneira que hai dez anos, sen grandes obrigas nin presións, conseguimos que aparecesen debates espontáneos entre eles á hora de considerar se unhas ou outras eran mellores ou peores, de forma que, case sen querer, estaban falando de elementos químicos, da maneira de ordenalos, dos nomes dos grupos ou familias, das propiedades que aparecían, da gran cantidade delas atopadas, de cómo se dicía tal ou cal elemento en diferentes linguas, etc. O propósito aquí é mostrar unha parte do resultado desta actividade, sendo o proceso o verdadeiramente importante, e non tanto as imaxes que de seguro son coñecidas por moitos e moitas.

Published: January 2022

ABSTRACT The Tian Shan and Pamir-Alay mountains of Central Asia are generally regarded as the primary center of diversity of Tulipa species, but a comparative morphological description of Central Asian Tulipa species is still lacking. To fill the existing gap, we studied 48 Tulipa species found in Central Asia plus one outgroup (Erythronium caucasicum) for 24 morphological characters of bulbs, leaves, stems and flowers. The obtained data matrix was subjected to a cladistic analysis. Although bootstrap values were low, the morphology-based tree more or less corresponded to previous classifications, except for the placement of sect. Clusianae and T. butkovii.

Published: January 2022

The electrical properties of metal-organic-chemical-vapour-deposited copper zinc sulphide (Cu-Zn-S) thin films on soda-lime substrates were studied. The films produced were characterized in terms of their electrical properties employing the Four-point probe procedure at a temperature range of 370 to 470°C. The electrical properties (resistivity and conductivity) of the deposited copper zinc sulphide films were systematically studied in terms of the deposition parameters of concentration and deposition temperature. The conductivity was in the interval of 5.48 to 8.0 × 10-1 (Ω.cm)-1. Activation energies of 0.54 and 0.29 eV in the deposition temperature range were estimated. The high resistive property of the films re-emphasized the potential use of these materials as active semiconductors for optoelectronic device applications.
Callus Formation and Regeneration Tendency of Justicia vasica Nees under Saline Conditions
Authors: Kader Abdul , Narayan Sinha Sankar , Ghosh Parthadeb
Published: January 2022

Salinity is one of the major environmental threats to plants because a large number of plants are intolerant to NaCl stress. One such plant, Justicia vasica, which is the subject of our study, is said to have great medicinal properties. However, the natural occurrence and cultivation of this species has been constrained due to various factors including its poor seed germination rate under its normal conditions of habitat, and a low availability of seeds. This study was undertaken to examine the efficiency of callus formation and regenerative tendencies of Justicia vasica under saline conditions. The leaf, shoot tips and inter nodal cuttings were employed for this study using MS media formulated with several concentrations of different kinds of hormonal combinations. This study also tested the effects of different concentrations of NaCl on callus induction and growth. Each experiment was conducted thrice with 12 replicates. A superior level of callus formation was achieved by treating shoot tips with 2.0 mg/l α-naphthalene acetic acid (NAA) and 0.5 mg/l 6-benzyladenine purine (BAP) in combination. From this study, it was concluded that there was no inhibitory action from the medium supplemented with 0.05 mg/l NaCl. The optimal hormonal combination also exhibited highest rate of callus induction and growth with 0.05 mg/l NaCl added. There was no callus necrosis at this saline concentration after 60 days of inoculation. Furthermore, some somatic embryogenic callus displayed the organogenesis of leaf like structures after 75 days of inoculation. The development of salinity tolerance of plants by genetic application has been a vital area on modern agriculture as well as medicinal plant research because more land has been salinized through poor local irrigation practices. The present investigation assumed that the NaCl tolerance of this plant could be effectively obtained in vitro.

The paper examines in detail the environmental impact of foaming agents used for extinguishing Class B fires, which include oil and petroleum product fires. There is a significant negative impact on the environment of long-chain fluorine-containing foaming agents and the search for alternatives of their use for firefighting. The advantages of calculation methods for determining the environmental parameters of foaming agents to extinguish fires, taking into account their chemical structure, are noted. The method «Quantitative Structure - Property Relationships» was used for obtaining BCF, LC50 (Fathead Minnow, Daphnia Magna), IGC50 (Tetrahymena Pyriformis) for a number of foaming agents with a carbon chain length C8-C14, containing fluorine and fluorine-free. It is shown that according to BCF the safest is sodium lauryl sulfate, according to LC50 (Daphnia Magna) the safest of the studied are foaming agents based on alkyl compounds Sodium decyl sulfate, Sodium lauryl sulphate, Triethanolamine salt of deсyl sulfate (third class of acute toxicity), whereas fluorine-containing compounds (6:2 fluorotelomers) according to LC50 (Daphnia Magna) belong to the first class of acute toxicity (the most dangerous of the studied compounds). Keywords: fluorine-free foaming agent; fluorotelomer; oil; petroleum products; extinguishing the fires; environmental parameter; calculation method.

In-situ combustion (ISC) is a proved, effective method for enhanced oil recovery (EOR). In our previous work, we studied the feasibility of ISC process for heavy oil recovery in Nurlat Oil Field (Tatneft oil company, Russia) regarding to oil recovery, in-situ oil upgrading, stability of combustion front, etc. In this work, we investigated the effect of ISC process on the rock properties and composition. We found that magnetic minerals can be in-situ formed in rock during combustion process of oils. The formation of magnetic minerals in rock depends on temperature, heating time, and oil environment. Based on the magnetic properties, the samples can be divided into the most heated, less heated, and nonheated ones with hydrocarbons. The changes in the magnetic properties of rock can be used for developing technologies for combustion front monitoring, which is very valuable for controlling ISC process and its adjustment. Keywords: magnetic properties; thermomagnetic analysis; enhanced oil recovery; in-situ combustion; rock.

Climatic conditions can also act as harmful factors from which the employee must be protected. But winter conditions are very different depending on the area of the country. Therefore, the standard regulations governing the issuance of warm clothing have established norms depending on climatic zones. The main disadvantage of the existing work clothing is insufficient resistance to the effects of oil and oil products, the inconsistency of the physiological and hygienic properties of the materials used with the production conditions. This causes significant damage to the health of workers in the production of acids and significantly reduces labor efficiency.

Enchantress or Victim?—The Deprived Voice in “La Belle Dame sans Merci: A Ballad”
Authors: Wang Xin
Published: January 2022

According to the knight’s narrative in “La Belle Dame sans Merci: A Ballad”, “la belle dame” is a deceptive temptress, who has a mysterious tryst with him and forsakes him mercilessly. Apparently, in his narrative, he falls victim to the mysterious lady. However, the truth tends to be ignored that the lady is rarely heard in the poem since her voice of resisting the knight’s fantasy world is deprived and covered by his narrative. As to the motivations, critics usually attribute Keats’s deprivation of female voice to his fear of Fanny Brawne, his charming lover’s sexual beauty. However, a close reading of textual details in the poem provides more interpretations of the deprived female voice. First, through the deprivation, Keats suggests his resistance against the power of a female lover as well as a female reader, and thus exhibits his endeavor and ambition to establish a masculine poetic identity among women readers. Besides, it indicates his combat against the anxiety of influence from George Gordon Byron’s literary success.

Authors: Aslan Hazal Rümeysa , Tolan Özlem Çakmak
Published: January 2022

This study aimed to determine the relationships between social appearance anxiety, automatic thoughts, psychological well-being and social media addiction and the predictive power of these variables on social media addiction. The sample of the study consists of 440 associate degrees, undergraduate and postgraduate students studying in various universities in Turkey. Demographic Information Form, Social Media Addiction Scale, Automatic Thoughts Scale and Psychological Well-being Scale were used as data collection tools in the study. Independent group t-test, one-way ANOVA, Pearson correlation coefficient and hierarchical regression analysis methods were used for the analysis of the obtained data. As a result of the analysis, it was found that there was a positive correlation between social appearance anxiety, automatic thoughts and social media addiction and a negative correlation between social media addiction and psychological well-being. According to the analysis, it was concluded that automatic thoughts and social appearance anxiety significantly predicted social media addiction, while psychological well-being did not significantly contribute to the model. Findings were discussed in light of the relevant literature.

Comportamentos indisciplinados em sala de aula: o que professores e estudantes pensam e fazem
Authors: Wecker Ilário , Albuquerque Alessandra Rocha de
Published: January 2022

Comportamentos indisciplinados são comuns entre estudantes de escolas brasileiras e têm impacto na trajetória escolar destes. Este estudo identificou a compreensão de indisciplina por professores e estudantes de uma escola privada confessional do DF e verificou a ocorrência de comportamentos de professores e estudantes, relacionados à indisciplina, em sala de aula. Oito professores e quatro estudantes do Ensino Fundamental foram entrevistados e diretamente observados. Foi evidenciada a compreensão de indisciplina como um fenômeno multideterminado de violação às regras e o uso de estratégias reforçadoras para lidar com comportamentos indisciplinados. Foram observadas discrepâncias entre o que os professores e estudantes relataram fazer e o que fazem e a ocorrência de comportamentos indisciplinados pelos estudantes. Concluiu-se, a partir da compreensão multicausal do fenômeno, que o manejo desses comportamentos deve envolver diferentes atores no contexto escolar e familiar e não ser focado apenas no estudante.

Grammatikken som system og mulighet Grammatikken forklart og praktisert i to lærebøker for ungdomstrinnet
Authors: Siljan Henriette Hogga
Published: January 2022

Denne artikkelen undersøker hvordan grammatikk er forklart og praktisert i to norsklærebøker for ungdomstrinnet; Kontekst 8-10 (2020) og Synopsis 8-10 (2020). Nærmere bestemt ser jeg på hvordan lærebøkene balanserer systemisk grammatikk og grammatikk i et overordnet tekstperspektiv. Skillet mellom språksystem og språkbruk har en lang tradisjon både innenfor språkvitenskap (Iversen et al., 2011) og i skolefaget norsk (Haugen, 2019), og gjennom norskfagets historie har grammatikkundervisningen på bakgrunn av dette blitt legitimert og praktisert på ulike måter. Med utgangspunkt i de nevnte begrepene samt føringer i den nye norsklæreplanen (LK20), har jeg funnet at lærebøkene vektlegger arbeid med grammatikken som system. Grammatikk i et overordnet tekstperspektiv blir i svært liten grad blir tematisert i Synopsis, mens det i større grad kommer til uttrykk i Kontekst. I begge læreverk finnes nokså knappe teoretiske ordklassebeskrivelser, og vi finner få grammatikkoppgaver som gjør bruk av det grammatiske begrepsapparatet utenfor grammatikkapitlene. I tillegg inneholder Synopsis nokså få oppgaver også i grammatikkapitlet, noe som samlet sett betyr at elevene tilbys få eksplisitte muligheter til å tenke, snakke og skrive om grammatikk. I Kontekst får elevene flere og mer varierte invitasjoner til grammatikkarbeid. Selv om rundt halvparten av grammatikkoppgavene her knytter sammen grammatikk og tekst, er det imidlertid relativt få av disse som tydelig tematiserer grammatisk tekstfunksjon.
La memoria compartida por las palabras de un transmisor de la historia: Manuel Vázquez Montalbán
Authors: Owczarczac Anne-Sophie
Published: January 2022

El proceso transicional español, a pesar de la voluntad de pasar página vio insurrecciones de olas memoriales por una gran parte de la ciudadanía. El “deber de memoria” anhelado por los españoles encontró confrontaciones con el “deber de paz” por parte de la corona española y del nuevo gobierno formado por el rey. Esta investigación se focaliza en la memoria silenciada, la memoria republicana investigando los archivos de un soporte de memoria imprescindible que es la prensa. La prensa del tardofranquismo – de oposición al régimen dictatorial – permitió diseminar una cultura alternativa, crear una conciencia colectiva, entrar en contacto y sensibilizar a los españoles sobre la actualidad. Además, el vínculo prensa-memoria parece incontestable porque el discurso periodístico es un discurso memorial por excelencia. Manuel Vázquez Montalbán fue, sin lugar a dudas, una figura emblemática del compromiso español del siglo XX, por su colosal pero también singular obra, por su estilo de escritura particular, y sobre todo, por su abanico de soportes en los que su escritura permanece más allá del tiempo y de la memoria. Vázquez Montalbán no escribió de espaldas a la historia sino que se enfrentó a ella y este estudio lo demuestra investigando las revistas Por Favor y Triunfo durante el año clave 1975.

Hellige skrifter i skolens religionsundervisning
Authors: Flø Geir Magne , Mogstad Sverre Dag
Published: January 2022

I denne artikkelen undersøker vi hvilke faktorer som kan bidra til elevers involvering i ­arbeidet med hellige skrifter i videregående skole. Tidligere forskning har belyst dette i svært liten grad, og for å kaste lys over temaet, analyserer vi semi-strukturerte intervjuer med fem elever som har religion og etikk. Rammeverket er sosiokulturelt, og det teoretiske grunnlaget er aktivitetsteori (Engeström), religionsvitenskap (Watts), medievitenskap ­(Hjarvard) og hermeneutikk (Ricoeur). Analysen viser at nyhetsmediene spiller en sentral rolle i ­tekstarbeidet og i elevenes tolkning av undervisningen. Dessuten viser vi, med utgangspunkt i Ricoeurs hermeneutikk, hvordan elevene filtrerer vekk objektive aspekter ved de hellige tekstene, enten med utgangspunkt i troen på vår egen samtids fortreffelighet eller utfra deres forståelse av religionsfagets egenart. Avslutningsvis diskuterer vi de didaktiske implika­sjonene av funnene.

Sustainable Economic Growth in the European Union under COVID-19 Conditions
Authors: Banelienė Rūta
Published: January 2022

All countries of the European Union (EU) have had their economies impacted by COVID-19 and should focus their efforts on managing the negative impacts on their GDP growth. Since EU countries vary considerably in many criteria, the same policy would not fit all EU countries. This paper analyzes how sustainable economic growth could be maintained in the long run while considering three criteria, including R&D investment, gross value added per employee and country size by population; and which factors could have the highest impacts on economic growth in the recovery process according to supply and demand. Countries were examined according to the mentioned criteria by applying the panel least squares method. The major estimation outputs show the stronger effect of the supply side on economic growth, the higher role of human capital in small EU countries where R&D investment exceeds 3% of GDP, and the critical effect of exports on GDP growth in the large EU countries with the lowest R&D investment. This segment depends the most on smooth exports of goods and service flows and could be the most vulnerable under COVID-19 conditions. Therefore, seeking to keep economic growth on track, EU countries should use different strategies and fiscal measures depending on the most vulnerable factors for their economic growth. In addition, this is the right time to revise values of economic growth, and governments should be more focused on the recovery of their economies on the sustainable development goals (SDGs) agenda.

: The current study aimed to design strategies to develop women’s health and physical activities in Iran. This study was drafted in the descriptive-correlational framework following an applied objective. The population of the study in the qualitative section consisted of 10 professors of sports management and sociology and in the quantitative section consisted of 160 experts (e.g., female sports managers and experts, women’s sports activists, and professors of sports management) selected through a purposive and comprehensive sampling method. Data collection was performed through a 20-items questionnaire drafted to examine the four fundamental factors of the study (e.g., management, social, economic, and cultural factors). The content validity and face validity of the questionnaire were confirmed by 10 university faculty members. The structural equation modeling in PLS software (version 3) was used to analyze the statistical data. The findings of the study indicated that among the study variables, the variable of management in the development of health and physical activities, with a correlation level of 75% and at a value of 5.696, was considered the most effective variable. Furthermore, among the essential elements of the study, in the cultural factor, the effect of the social values and beliefs in the participation of women in sports activities was reportedly at a correlation rate of 87%. In the management factor, the assignment of management roles to women in sports was at a correlation rate of 85%. In the economic factor, the element of budget allocation to women’s sports was at a correlation rate of 73%. In the social factor, the impact of the Ministry of Health and Education and the Ministry of Sports and Youth in creating sports events for the development of women’s health in the various provinces of Iran was at a correlation rate of 92%. All of the aforementioned items were among the most contributing factors in the essential elements of the study. In conclusion, it can be stated that the Ministry of Sports and Youth and the Federations of Public Sports succeeded to initiate programs in the development of Iranian women’s health and sports by employing a comprehensive plan that included allocating budget, highlighting the role of women in the sports management positions, and cooperating with different agencies and organizations.

Background: The spread of Coronavirus Disease 2019 (COVID-19) caused restrictions and shutdowns affecting the economic situation, employment, and the educational needs of society. Meanwhile, the universities of medical sciences have faced serious problems in education. Objectives: The present study aimed to assess the satisfaction of the students of Qaen and Ferdows medical schools with virtual education during the COVID-19 epidemic. In addition, the factors effective in this satisfaction are investigated. Methods: This descriptive-analytical (cross-sectional) study was conducted at Qaen School of Nursing and Midwifery and Ferdows School of Paramedical Sciences and Health, Iran, using a researcher-made questionnaire provided to students online. The study population was all the students of these two faculties. The sample size was estimated as 285 people using the Morgan table, and 296 individuals participated in the study. Data were collected and analyzed using descriptive and inferential tests by the SPSS software version 24. Results: Our findings showed that most (40.2%) students had moderate satisfaction, and only 5.74% had very high satisfaction with virtual education. The mean satisfaction of female students was higher than males without a statistically significant difference (P = 0.4). Moreover, the results of the analysis of variance revealed that the level of the academic satisfaction of students is different in distinct academic levels (P = 0.007). In addition, Pearson’s correlation coefficient indicated a significant positive correlation between age and academic satisfaction score (P = 0.001, r = 0.185). Conclusions: Overall, the results of the present study showed that less than half of the students were moderately satisfied with virtual education. According to the students, this dissatisfaction mainly results from the lack of a suitable infrastructure for virtual classes. Usually, satellite branches are weaker than the main university in terms of facilities and equipment, and solving these problems requires the special attention of education officials and managers.

Published: January 2022

This paper presents results of a malacological survey of the Chrudimka River between the town of Chrudim and the junction with the Labe (Elbe) River; the territory of the Dolní Chrudimka Site of Community Importance (SCI). Twenty-three species of aquatic molluscs (11 gastropods and 12 bivalves) were found at 21 sites during the research in 2013, 2015 and 2016. The occurrence of a population of rare bivalve Pseudanodonta complanata was recorded in the lower stretch. The research was focused on the population of the endangered bivalve Unio crassus which occurrence was confirmed at nine sites, however its population density was always low. The Chrudimka site is nowadays the only site with the occurrence of this bivalve known in Pardubice Region (Czech Republic, Eastern Bohemia).

Com o objetivo de definir qual o melhor volume de tubete e o tempo de permanência das mudas de Senegalia bahiensis em viveiro, foram instalados dois experimentos em delineamento inteiramente casualizado. No primeiro experimento, as mudas foram produzidas em três volumes de tubetes (55, 180 e 280 cm³), constituindo os tratamentos, quatro repetições e 49 mudas por repetição. No segundo experimento, foi realizada uma simulação de campo utilizando duas mudas por repetição, totalizando 24 mudas. As variáveis analisadas foram: altura, diâmetro, massa seca da parte aérea e do sistema radicular, número de folhas, incremento médio diário em altura e incremento médio diário em diâmetro. As mudas produzidas no recipiente de menor volume (55cm³) obtiveram as menores médias para todas as variáveis analisadas, tanto na fase de produção de mudas, como na simulação de campo. Em função dos resultados obtidos nos experimentos, conclui-se que para a espécie Senegalia bahiensis, por sua produção de mudas apresentar qualidade semelhante quando foram utilizados tubetes de 180 e 280 cm³, recomenda-se o uso do tubete de 180 cm³, o qual, além de apresentar redução do ciclo de produção em no mínimo 33 dias, reduz o uso de insumos, nas condições em que os experimentos foram conduzidos.

O objetivo deste trabalho foi avaliar a fenologia de Lafoensia pacari St. Hill. em duas áreas de Cerrado Mato-Grossense que se distinguem pela fitofisionomia: Cerradão e Cerrado sentido restrito, entre fevereiro de 2015 a janeiro de 2017, utilizando o índice Fournier. Correlacionaram-se as fenofases queda de folhas, brotação, floração e frutificação, com as variáveis ambientais: temperaturas máxima e mínima, umidade relativa e precipitação. A queda foliar ocorreu nos meses de julho e agosto de 2015, com 80 e 84%, e em 2016 entre agosto e setembro com 92 e 88% nas áreas 1 e 2, respectivamente. A queda das folhas se intensificou no auge do período de seca nas duas áreas. A brotação se iniciou no período chuvoso nas duas áreas. Botões florais foram observados no final do período chuvoso e por todo o período seco nas áreas 1e 2, entre os meses de maio a julho de 2015. Em 2016, os botões florais foram observados de abril a agosto na área 1 e em março na área 2. Na área 1, o pico de intensidade dos botões florais ocorreu em junho de 2015 e em maio de 2016, com 14 e 25%, respectivamente. O índice de intensidade de botões foi inferior a 2% na área 2. O pico de intensidade da antese na área 1 ocorreu em maio de 2015 e em junho de 2016, com 9 e 17%, respectivamente. O índice de intensidade de floração atingiu valores inferiores a 2% na área 2. O índice de intensidade de frutos imaturos e maduros apresentou valores inferiores a 8 e 5%, respectivamente, na área 1. Na área 2, não foi observado o processo de frutificação.  Lafoensia pacari apresentou intensa senescência das folhas no auge do período seco. Os indivíduos da área de Cerradão apresentaram maior desempenho, principalmente das fenofases reprodutivas.

Os problemas relacionados à combustão da biomassa e o seu impacto sobre a eficiência das caldeiras dependem das características do combustível e do projeto e operação dos equipamentos. Assim, este estudo teve como objetivo mapear os problemas associados à geração, coleta e tratamento das cinzas da biomassa florestal queimada em caldeiras industriais. O estudo foi realizado em uma usina termelétrica que gera 28MW/hora e usa biomassa florestal como combustível. Foram feitas três coletas de cavacos de madeira, antes da entrada na fornalha da caldeira e em quatro locais de passagem de cinzas na caldeira, onde ocorre o tratamento e recolhimento para disposição final deste resíduo da biomassa. Parte do mix de biomassa foi calcinado em laboratório para comparação entre os pontos de amostragem com as propriedades da biomassa. As propriedades analisadas foram: composição química elementar inorgânica; teste de fusão das cinzas e a potencialidade de ocorrência de problemas por meio dos índices de: deposição das cinzas (R); escória (Rs); incrustação (Fu); viscosidade (Sr) e álcali (Al). Os compostos presentes em maior concentração nas cinzas foram os óxidos de silício, alumínio, ferro, cálcio, potássio e magnésio. A temperatura de fusão das cinzas foi entre 1261°C e 1385°C. O mapeamento dos problemas apontou baixos riscos de formação de escória e viscosidade. O índice de incrustação foi alto para o decantador (0,69) e o readler teve médio potencial de viscosidade (1,11). A formação de álcali ocorreu no readler e decantador, provocando corrosões nestes pontos. Os cálculos dos índices de deposição foram capazes de expressar os problemas que ocorrem na queima da biomassa florestal em caldeira.
