The most crucial aspect of the learning process is memory. There is no knowledge without memory. However, mostpeople lack memory because they memorize things through rote memorization. So in this paper, we implementeda deep neural network (DNN) model that converts plain text into a song, which is done by synchronization of aMusical Instrument Digital Surface (MIDI) file or the music with the text. MIDI files are symbolic representations ofthe music score. The melodic line of the composition is normally on one of them, while the background music ison the others. Analyzing the audio to identify voice portions where a human voice is present, as well as non-voicesegments in proximity to the voice segments, is part of a method for syncing text with audio. The text segmentsof segmented text related to the audio can be recognized and synchronized to the speech segments.

In general, the company sometimes uses unregistered functions in database, which significantly improvesperformance, but does not leave the possibility of recovery except for backup. That is, actions must be performedimmediately after passing the session. A queue problem is likely to cause data loss and downtime of about aweek. In modern conditions, this can lead to the bankruptcy of the company. It can be seen that backup systemshave been installed and configured, but despite this, they have not succeeded in restoring within the time framespecified in the SLA. In this study, a secured database monitoring method was proposed to improve data backupand recovery operations in cloud computing. In this proposed method, the backup speed is directly proportionalto the amount of data, while having at least 30% annual data growth. In 3–4 years, the data at least doubled, butfor some companies, this number is even higher, while the backup speed does not change. Those terms and thoseSLAs that were relevant 3–4 years ago now need to be at least doubled. At the same time, business requirementsfor data recovery (recovery point objective/recovery time objective) continue to grow.

Financial institutions use various data mining algorithms to determine the credit limits for individuals using featureslike age, education, employment, gender, income, and marital status. But, there is still a question of accuratepredictability, that is, how accurate can an institution be in predicting risk and granting credit levels. If an institutiongrants too low of a credit limit/loan for an individual, then the institution may lose business to competitors, butif the institution grants too high of a credit limit/loan, then the institution may lose money if that individual doesnot repay the credit/loan. The novelty of this work is that it shows how to improve the accuracy in predictingcredit limits/loan amounts using synthetic feature generation. By creating secondary groupings and includingboth the original binning and the synthetic bins, the classification accuracy and other statistical measures likeprecision and ROC improved substantially. Hence, our research showed that without synthetic feature generation,the classification rates were low, and the use of synthetic features greatly improved the classification accuracy andother statistical measures.

Authors: Kaponda Peggy , Kawimbe Sidney , Kombe Charity Meki , Mwange Austin
Published: October 2023

The paper is a review of critical success factors for Business Re-Engineering Processes Implementation. Business process re-engineering (BPR) has emerged as a crucial strategy for organizations seeking to adapt to rapidly changing business environments and improve operational efficiency. Successful implementation of BPR projects is contingent upon a comprehensive understanding of the critical success factors (CSFs) that drive their effectiveness. This literature review aims to explore and synthesize the key CSFs for business re-engineering processes implementation by analyzing a broad range of academic and industry sources. The review begins by providing an overview of the evolution of BPR, its rationale, and its significance in contemporary business contexts. Subsequently, it delves into an extensive examination of the literature to identify and categorize the CSFs that have been consistently highlighted in research and practical applications. These CSFs encompass various dimensions, including organizational culture, leadership commitment, stakeholder involvement, change management, information technology adoption, and performance measurement. Furthermore, the review explores the interrelationships and dependencies among these CSFs, highlighting the need for a holistic and integrated approach to BPR implementation. It also discusses the evolving role of technology, especially emerging trends such as artificial intelligence and robotic process automation, in influencing the success of BPR initiatives. By synthesizing and synthesizing the existing literature, this review aims to provide valuable insights for practitioners and researchers involved in BPR projects. It underscores the importance of considering multiple CSFs and their interactions when planning and executing BPR initiatives, offering a foundation for developing effective strategies and frameworks to maximize the likelihood of successful outcomes. Additionally, it identifies gaps in the literature and suggests directions for future research, encouraging further exploration of this critical area in the field of business process management.
Major Models and Theories of Cryptocurrency Technology Adoption: A Theoretical Review
Authors: Mweetwa Larry , Mwange Austin
Published: October 2023

A review of a selected theories that influence the adoption of technology will serve as the objective of this paper. In this work, we attempt to discover traits that might improve the possibility of acceptance and ongoing usage of technology such as cryptocurrency adoption. More specifically, we focused on Rogers' Innovation Diffusion Theory (IDT, Theory of Technology Acceptance (TAT), and Technology Acceptance Model. (TAM)/TAM2/TAM3, Theory of Reasoned Action (TRA), Unified Theory of Acceptance and Use of Technology (UTAUT), and Theory of Planned Behaviour (TPB). When researching the tendency of individuals to adopt certain technologies, researchers draw from a wide variety of conceptual frameworks and analytical approaches. In this review, social psychology and its applied notions have been utilised most frequently. As a primary theoretical foundation, the theories centre on people's intentions to engage in a specific behaviour (i.e., adopt and utilise ICT), which is the emphasis of the theories. Research on the adoption and usage of information and communication technologies has made extensive use of both the Theory of Reasoned Action (TRA) and the Theory of Planned Behaviour (TPB). They are two of the key intention-based theories, which means they give the core theoretical underpinnings for other adoption theories, such as the Technology Acceptance Model (TAM) and the Enhanced Technology Acceptance Model. Both the transpersonal relationship analysis and the transpersonal behaviour analysis begin with the fundamental premise that individuals deliberately choose whether or not they will engage in a certain behaviour. In this sense, the adoption and usage intentions are typically seen of as a primary outcome variable that is influenced by a variety of independent variables. This is because of the way that they are typically studied. In the following, we will discuss significant theories regarding the adoption of technology.

The individual investors would like to know the investment avenues so that they can use their discretion and invest in those avenues, which will give them security and stable return. The ultimate aim of the individual investors is to find a variety of investment avenues that meet their preference for risk and expected return. The investment avenues like financial and physical assets have a wide range of risk from risk-free to highly speculative avenues. From this broad spectrum, the individual investors will have to select these avenues that maximize their utility. The investment decisions are influenced by some factors such as preferences, size of amount involved, safety of funds, regular and steady returns, easy accessibility and manageability of assets, etc. Hence, individual investors are to choose financial and physical assets that fulfill their future expectations
Visual Cryptography-Based Secure URL Sharing System: Design and Implementation
Authors: Ahlawat Dhruv Kumar
Published: October 2023

In this paper, we describe the design and implementation of a secure URL-sharing system based on Visual Cryptography, that is, QR codes that have been extensively used in recent years because they speed up the process and provide users with ultimate convenience. However, as convenient as possible, regular URL- sharing systems are vulnerable to different types of attacks. Therefore, sharing must be sufficiently secure to protect integrity and confidentiality. Moreover, the URL sharing system must provide authenticity for both the sender and receiver. In this study, the security of the proposed QR-based system was demonstrated using visual cryptography. The proposed system comprises a mobile application that implements visual cryptography. The application provides a simple and user-friendly interface for users to conduct payment transactions in a user-friendly secure environment.

Policy Uncertainty and the Volatility of the S&P 500: Before and After the Launch of the S&P 500 ESG
Authors: Mahjoubi Manel , Henchiri Jamel Eddine
Published: October 2023

This paper examines the asymmetric effect of economic policy uncertainty, geopolitical risk, and climate policy uncertainty on the volatility of the S&P 500 stock index, before and after the launch of the S&P 500 ESG Index, by using a Non-linear Autoregressive Distributed Lag (NARDL) model, for the period January 2010 to august 2022.We provide evidence on the asymmetric impact of climate policy uncertainty on the volatility of the S&P 500 both in the short-run and in the long-run, and this asymmetry is more frequent after the launch of the S&P 500 ESG Index. Moreover, in the long-run, a decrease in the economic policy uncertainty after the launch of the S&P 500 ESG has greater effect on volatility of the S&P 500, than the short-run. We also find that positive and negative shocks to geopolitical risk before and after the launch of the S&P500 ESG index do not affect the volatility of the S&P 500 stock market index in the short -run and long.
Personality and Political Activity of Otto von Bismarck Through the Eyes of the Russian Political Elite during the second half of the 19th century
Authors: Kosmach Alena Eskridge
Published: October 2023

The attention towards the figure of Bismarck, known as the "Iron Chancellor" was connected with the fact that when he was in the highest positions of the government the relations between the Russian Empire and Germany were developing along very dramatic lines.  Bismarck was one of the very few state officials who respected the Russian Empire and considered it as one of the most important participants in the European political game. According to his understanding, the views of the Russian political elite were very important to the governments of every European country. Taking into consideration these circumstances, it is important to trace the different aspects of the public opinion of the Russian political and intellectual elite which were expressed in the documents of the second half of the 19th century.

Published: October 2023

The present study adopted a mixed-methods sequential explanatory design to explore the status of nurturing creativity in Iranian EFL classrooms. A standard questionnaire was given to 214 public high school EFL teachers to rate the frequency of using creativity-nurturing strategies in their classrooms. While the curriculum policies stipulate creativity-nurturing strategies, the results suggested that the teachers do not frequently adopt the strategies. Further, interviews were conducted with the teachers to find out the factors hindering the teachers from using these strategies. Deductive thematic analysis of interview transcriptions led to the extraction of five themes regarded as attributes to the inability of Iranian EFL teachers to adopt creativity-nurturing strategies. The findings imply that the existence of performativity in Iranian EFL classrooms creates pressure and dilemma for EFL teachers to teach for creativity. Issues such as time, exams, and pressures of the curriculum strictly constrain the creativity-nurturing practices of these teachers. Generally, modifications need to be supported in various aspects of teaching English in Iran to help the teachers nurture creativity in the classrooms.

Math education and the human right to inclusion: the expectations of the teacher acting with deaf pupils in a public school in the Distrito Federal
Authors: Silva Simone Aparecida dos Santos , Pedroza Regina Lucia Sucupira
Published: October 2023

This study presents math teachers and their expectations regarding the school inclusion process, as a human right, for deaf students. It presents mathematical education as knowledge that dialogs with the perspectives of human rights, in particular, with the right to education. It has as participants in the research six mathematics teachers who work in a public high school, located in the Gama Administrative Region, Federal District, Brazil. The qualitative methodology was used with a dialogical instrument of semi-structured interview and discourse analysis. As a result, it was found that many teachers have propositive expectations regarding the inclusion of the deaf learner, although much of the emphasis is on the acquisition of Brazilian Sign Language rather than methodologies and teaching processes suitable for this audience. As for their training to promote inclusion, there was a negative expectation, since four of the teachers said that they were not prepared. However, all have demonstrated in their narratives the importance of teaching mathematics and inclusion as a right to education, as well as a human right for all.
Study of case of the profile of Covid-19 infected in Espirito Santo State in Brazil
Authors: Passos Carlos Augusto Cardoso , Do Nascimento Jefferson Oliviera
Published: October 2023

The pandemic caused by Severe Acute Respiratory Syndrome - Related Coronavirus 2 (SARS-CoV-2) has made socio-economic inequalities between social classes more evident in the countries in development process.  This scenario is also no different in Brazil and it has been demanding from the federal, state and municipal governments broad efforts to combat the consequences of the spread of the disease in Brazil. The rulers have a huge challenge to implement measures to prevent the advance of the transmission of the virus. In addition, state governments need to use the public health system to serve the main population, since the lethality rate is very high directly influenced by social inequality. To minimize the effects of the new coronavirus, the ruler needs planning to give efficient response and requires an understanding of the rich that people about free movement, controlled circulation or total blocking of population movement. In this context, our proposal was to investigate how the disease reached people of different levels of education. And how has been the response of people hospitalized in Brazilian hospitals. We analyzed the public data of reports of Severe Acute Respiratory Syndrome (SRAG). In our research, we considered the variables schooling, ethnicity, gender, time of hospitalization in the Intensive Care Unit (ICU) and use of mechanical ventilators. Our results indicate that the lethality rate is higher for those people who were admitted to the ICU. In addition, people with low schooling and no schooling are 3.6 times more likely to die than people with higher education. This discrepancy highlights the huge disparity of quality treatment in Brazilian states.

Bio-oil is a byproduct of the thermal decomposition of organic materials under low concentrations of oxygen at controlled temperatures. This product is commonly used as a potential soil conditioner. However, as it is of plant origin, this product may also have secondary metabolic properties capable of assisting in the alternative management of agricultural pests. Therefore, this work aimed to evaluate the acaricidal effect of bio-oil based on coffee straw and eucalyptus bark, obtained at a temperature of 600 ºC, on adults of the red mite Oligonychus ilicis. The treatments were calculated on a logarithmic scale, and the concentrations of the bio-oil solutions were 1.00; 1.58; 2.51; 3.98; 6.31, and 10.00 % (v v-1). Each solution was applied on mite adults, each treatment consisting of 7 Petri dishes, with 12 red mite individuals per dish. The experimental units consisted of coffee leaf disks (4 cm in diameter), with cotton moistened around these disks to prevent the mites from escaping. The application of bio-oil solutions on the mites was carried out directly, being sprayed with the aid of an Alfa 2 airbrush, connected to a calibrated compressor with a constant pressure of 1.3 psi. 2mL of solution of each concentration was applied. The experimental units were kept in a climate-controlled chamber (25 ºC, 70 % RH, 12h photophase). The acaricidal effect on adults was evaluated 24, 48, and 72 hours after spraying the solutions. Mortality data were submitted to Probit analysis (p≤0.05) using the R statistical program. Coffee bio-oil and eucalyptus bio-oil caused mortality in O. ilicis in a dose-dependent manner, with an estimated LC50 of 1.52 and 2.15 % (v v-1), respectively. The estimated LC90 of these bio-oils was 5.90 % and 8.02 % (v v-1), respectively, indicating that doses lower than the maximum concentrations used caused almost all the mortality of individuals under controlled environment conditions. Thus, it is concluded that the coffee straw bio-oil, as well as the eucalyptus bio-oil, have a high potential for use in the alternative management of adults of the red coffee mite O. ilicis.

O Brasil possui mais de 10% do território composto de Terras Indígenas, Áreas Quilombolas e Unidade de Conservação visando a conservação da biodiversidade in situ. Entretanto, para a maioria das espécies não há estratégia de conservação ex situ via sementes. Desta forma, o objetivo do presente trabalho é a avaliação da tolerância à dessecação e armazenamento de sementes de Erythroxylaceae da Amazônia. Uma revisão de literatura on line foi realizada com os seguintes termos, nas Línguas Portuguesa, Espanhola e Inglesa: “sementes Erythroxylaceae”, “armazenamento Erythroxylaceae”, “secagem Erythroxylaceae”, “sementes Erythroxylum”, “armazenamento Erythroxylum”, “secagem Erythroxylum”. Houve registro de informações sobre a tolerância à dessecação ou armazenamento de sementes ou conservação de sementes para apenas 12 espécies. A maioria das espécies de Erythroxylaceae da Amazônia apresentam teores de água acima de 45% após dispersão natural de suas sementes. Em sementes recentemente coletadas, a porcentagem de germinação de sementes está acima de 54%, exceto para as espécies E. deciduum A.St.-Hil. (3,7%) e E. campestre A.St.-Hil. (2,0%). Independente das formas de armazenamento, a perda de água reduz ou inviabiliza a germinação de suas sementes. As espécies da família Erythroxylaceae da Amazônia possuem sementes caracteristicamente recalcitrantes, ou seja, sensíveis a dessecação/secagem.

O maracujazeiro é uma das frutíferas mais produzidas no Brasil, porém, seu cultivo em condições de estresse hídrico promove efeitos negativos que podem afetar todos os seus estádios vegetativos. A produção de mudas de boa qualidade depende principalmente da disponibilidade de água, o que é um fator limitante em regiões semiáridas. O uso de polímero hidroabsorvente (hidrogel) tem se tornado uma estratégia para retenção de água no solo e redução da lixiviação de nutrientes. Com isso, objetivou-se avaliar a influência da aplicação de doses de hidrogel em mudas de maracujazeiro amarelo cultivadas em dois tipos de solos, com e sem estresse hídrico. A pesquisa foi desenvolvida em casa de vegetação, no Centro de Ciências Agrárias e Ambientais (CCAA) UEPB. Os resultados demonstraram que a condição de estresse hídrico com a manutenção de 40% da capacidade de campo, não foi atenuada pela aplicação de hidrogel, diminuindo o crescimento das mudas de maracujá cultivadas em ambos os substratos. O hidrogel aplicado na condição sem estresse hídrico aumentou o crescimento das mudas de maracujazeiro cultivadas em ambos os solos.

O financiamento em saúde sempre foi um desafio para a gestão do Sistema Único de Saúde (SUS), sobretudo por parte dos municípios. O objetivo da pesquisa foi analisar o financiamento do SUS e o processo de gestão orçamentário em municípios da macrorregião norte do Paraná. Trata-se de um estudo quanti-qualitativo realizado em uma região que possui 1.925.944 habitantes, totalizando 97 municípios. A etapa quantitativa ocorreu por meio de dados secundários. A etapa qualitativa contou com a seleção de alguns municípios para a realização de entrevistas semiestruturadas com contadores e gestores de saúde. Os resultados revelaram que foram os municípios que mais aumentaram a sua participação no financiamento, sobretudo os municípios menores.São eles também os que mais dependem dos recursos de transferência, os que mais investem em Atenção Primária à Saúde (APS) e os que possuem maior fragilidade não se transferem à constituição de equipes mais habilitadas para o desenvolvimento da gestão orçamentária. Embora os municípios menores não tenham percebido a redução no financiamento do Previne Brasil, é reconhecido que o programa passa a exigir da equipe gestora maior capacidade em promover a gestão orçamentária. A incerteza relativa aos repasses da União, a pouca participação dos estados em experimentar incentivos no âmbito da APS e a insegurança de executar os recursos vinculados levam a induzir os municípios a praticar cada vez mais a utilização de seus recursos próprios.Embora os municípios menores não tenham percebido a redução no financiamento do Previne Brasil, é reconhecido que o programa passa a exigir da equipe gestora maior capacidade em promover a gestão orçamentária.

O tratamento para queimaduras graves através de curativos biológicos a partir da utilização de xenoenxertia com pele de Tilápia tem demostrado melhores resultados que as modalidades tradicionais utilizadas. Diante disso, buscou-se avaliar os benefícios da terapia de xenoenxerto com pele de Tilápia-do-Nilo (Oreochromis niloticus) como curativo biológico no manejo e tratamento de queimaduras graves em relação a outros métodos tradicionais. Assim, a pesquisa consiste em uma revisão integrativa protocolada na plataforma FigShare, realizado em agosto de 2023, a partir de busca eletrônica na Literatura Latino-americana e do Caribe em Ciências da Saúde (LILACS), Scientific Electronic Library Online (SciELO), National Library of Medicine (PubMed), Biblioteca Virtual em Saúde (BVS) e Sistema Online de Busca e Análise de Literatura Médica (MEDLINE). Após a aplicação da estratégia de busca foram encontrados 204 estudos sendo excluídos 52 por estarem repetidos nas bases de dados e 143 por não atenderem aos critérios de inclusão. Dessa forma, a amostra final do constituiu-se de 9 artigos originais constatando redução na média de dias de tratamento, boa aderência ao leito da ferida, diminuição das trocas de curativos, ausência de antigenicidade e toxicidade, otimização da equipe e redução de custos hospitalates. As desvantagens encontradas estão relacionadas a não redução da dor após a aplicação do curativo. Contudo, há uma carência de estudos disponíveis na área por se tratar de uma descoberta recente, contudo este estudo ressalta a importância de continuar explorando a terapia com pele de Tilápia-do-Nilo como uma opção terapêutica valiosa no tratamento de queimaduras graves.
Advances and challenges to implementing the project: arsenic in Uruguayan groundwater and associated health risk

In Uruguay there is a great concern about the arsenic (As) geogenic contamination in groundwater as an environmental health problem, after rather high levels of As in groundwater in some areas (above 20 μg L-1) were reported and considering that the majority of the rural population consumes drinking water from private aquifer wells. On the other hand, Uruguay has an abundance of wells and quality groundwater, and it is vital to protect Uruguayan aquifers as important resources. In this respect we proposed and started to implement a multidisciplinary and interinstitutional program: AsURU Project (“Arsenic in Uruguayan groundwater and associated health risk”) (website: facebook.com/AsURUArsenico) to address this environmental and health problem. Although there are no systematic studies on the quality of groundwater or on the incidence of health effects associated with As exposure, a medical geology study is being performed by the research team led by Nelly Mañay, Ph.D., to assess health risks retrospectively by correlating reported cancer incidence with As groundwater levels, distributed by different localities. The AsURU Project has developed a working plan that consists of: (a) identification of main Uruguayan aquifers with relevant As data, (b) subdivision in study areas, (c) establishment of geographically delimited pilot areas following specific criteria: i) areas which have drinking water supplied by aquifers with As levels above WHO guidelines; ii) should represent a significative extension of the concerned aquifer; iii) have enough information about the aquifer hydraulic parameters and iv) availability of quantitative data about population´s exposure timeline to groundwater and shreds of evidence about health adverse effects (d) hydrogeologic, hydrodynamic and hydrogeochemical study to identify the origin of As and space-time mobility, (e) evaluation of As exposure through groundwater in the pilot areas, (e) recommend solutions like good construction and other remedial actions. The AsURU Project has seen great progress and also encountered challenges. Its main achievements in line with the proposed action plan have been: (1) the identification of pilot areas with As concentration levels in groundwater above 20 μg L-1 (max. permitted level as per Uruguayan regulations); and even with As level concentrations above 10 μg L-1 (max. permitted level as per WHO regulations). (2) the formation of three work groups to develop three related projects: the Groundwater Resource Group, the Chemistry and Medical Geology Group, and the North Littoral Group; (3) meetings were held, including the “I Symposium of Arsenic in Uruguayan Groundwater” in 2018, with the participation of various state-owned companies and the “II Symposium of Arsenic in Uruguayan Groundwater” in 2022. However, there is still no specific financial support for developing the program in its totality.
Ensino religioso: concepção histórica, fundamento legal e relevância na formação básica
Authors: Machado José Ronaldo de Freitas , Baratella Ricardo
Published: October 2023

Esse artigo traz concepções históricas concernentes à fundamentação do Ensino Religioso e sua relevância como disciplina curricular na formação básica. Dessa forma, a pesquisa se apoia em teorias de estudiosos da área da educação e objetiva-se a destacar a adequação do Ensino Religioso no Brasil, sua aceitação, assim como sua rejeição que começou no século XVI até a contemporaneidade. Outrossim, as exposições sobre o Ensino Religioso são elencadas desde a chegada dos jesuítas ao Brasil ainda no período colonial, trazendo consigo uma pedagogia denominada de Ratio Studiorum, segundo a proposta de sua época, num viés tradicional. Trata-se de uma pesquisa qualitativa e para essa investigação foi realizada a revisão de literatura. Apresenta algumas análises de como vem sendo retratada na atualidade a disciplina Ensino Religioso, sem a prática do proselitismo, procurando-se contextualizar e fundamentar-se principalmente na Constituição Federal (1988), nas matrizes da LDB 9394/96, DCN’s (2015) e na BNCC (2017, 2018). Dessa forma, conseguimos compreender melhor a magnitude dessa disciplina na formação do ser humano, os valores éticos e morais e reconhecer os melhores caminhos de vida, o que nos leva a diversas percepções, sentimentos e reflexões sobre os reais saberes construídos pela disciplina Ensino Religioso na educação básica.

Técnicas complementares de conservação como a criopreservação, representam uma opção segura e econômica para a conservação em longo prazo de germoplasma de espécies de sementes não ortodoxas, como é o caso da mangabeira. O sucesso da conservação do pólen depende de vários fatores, como o estádio fenológico da flor, a temperatura e umidade relativa do ambiente de armazenamento, assim como o seu próprio grau de umidade. O objetivo deste trabalho foi avaliar a viabilidade in vitro do pólen desidratado de mangabeira em temperatura ambiente e a conservação em temperaturas baixas. As inflorescências de quatro acessos foram coletadas do Banco de Germoplasma de Mangaba (acessos CP, GU, IP e PA), localizado no município de Itaporanga d’Ajuda, Sergipe, Brasil. O experimento foi realizado no laboratório de Cultura de Tecidos de Plantas da Embrapa Tabuleiros Costeiros. As inflorescências em pré-antese foram coletadas e, em laboratório, abertas cortando-se a parte do receptáculo até o pedicelo. Os grãos de pólen foram retirados das anteras com auxílio de um bisturi e pinça e inoculados em placas de Petri com meio de cultura de Lora, mantidos em temperatura ambiente por 0, 24, 48 e 72 horas. Para estudos de conservação foram colocados em criotubos para e armazenados no ultrafreezer (-20 ºC e -80 ºC), freezer (-4 ºC) e nitrogênio líquido (-196 ºC). Os dados da viabilidade do pólen dos ensaios foram submetidos à análise da variância pelo teste F a 5% de significância. Para os fatores qualitativos (acesso e condições de armazenamento) as médias foram comparadas pelo teste de Tukey 5% de probabilidade. Para os fatores quantitativos (tempo de desidratação) foram estimadas equações de regressão. Os resultados obtidos em relação à viabilidade in vitro dos grãos de pólen em temperatura ambiente demonstraram que os acessos CP e PA tiveram comportamento semelhante com as maiores porcentagens de germinação. O acesso CP teve a viabilidade máxima de 79,08% no tempo de 24h, a porcentagem do acesso PA foi de 72,12% no tempo 0. Em relação à conservação, as maiores médias de viabilidade por crescimento do tubo polínico foram observadas no acesso IP, com 53,38% e CP, com 38,34% a - 80 ºC após 72h de desidratação inicial das flores em sílica gel.
