Síntese de análogos de cantaridina e avaliação da atividade herbicida
Authors:   , Ferreira Kamylla Calzolari
Published: August 2022

O controle químico é uma ferramenta eficiente para minimizar as perdas na produtividade agrícola, no entanto, o uso contínuo do mesmo defensor agrícola e de forma indiscriminada pode causar, principalmente, a resistência de algumas pragas aos pesticidas. A busca por princípios ativos mais eficientes, menos tóxicos e menos persistentes tem sido uma alternativa para tentar reduzir os efeitos negativos da bioacumulação do uso dos pesticidas. Assim o potencial biológico apresentado por anidridos e amidas aliado ao fácil acesso sintético e presença de grupos funcionais com diferentes reatividades possibilita modificações estruturais com o intuito de produzir derivados com potencial biológico para serem utilizados em diversos setores, sobretudo na indústria de agroquímicos. O presente trabalho teve por objetivo sintetizar e caracterizar novas moléculas nitrogenadas visando avaliar a atividade herbicida desses compostos. A rota sintética escolhida teve como material de partida o 3R,4S,5R,6S-tetraidro- 3,6-epoxiisobenzofuran-7,8-diona (1), obtido através da reação de Diels-Alder entre anidrido maleico e furano com rendimento global de 91 %. O composto de partida (1) foi submetido a reações de adição de aminas aromáticas à carbonila em diclorometano anidro produzindo seis ácidos carboxílicos (2-7) em rendimentos que variaram de 92 a 99 %. Esses ácidos carboxílicos foram submetidos a reações de ciclização na presença de metanol e ácido sulfúrico concentrado levando a formação de seis imidas (8-13) em rendimentos que variaram de 60 a 83 %. As imidas foram submetidas a reação de epoxidação na presença do ácido meta-cloroperbenzóico levando a formação de seis epóxidos (14-19) em rendimentos que variaram de 62 a 98 %. Todos os compostos sintetizados foram caracterizados por espectroscopia no infravermelho, ressonância magnética nuclear de hidrogênio (RMN de 1 H) e de carbono 13 (RMN de 13 C) e temperatura de fusão. A avaliação da atividade herbicida das substâncias (2-19) foi feita através de teste de germinação com sementes de cebola (Allium cepa) e alface (Lactuca sativa) e comparadas com o herbicida comercial Dual Gold. Todos os compostos sintetizados (2-19) interferiram no desenvolvimento das plântulas de cebola e de alface. Os ácidos (2-7) tiveram atividade de inibição significativa, principalmente frente as plântulas de alface. Inibição de até 100 % para o ácido 7, na concentração de 1000 µM.Palavras-chave: Diels-Alder. Cicloadição. Ácido carboxílico. Imida. Epóxido. Cantaridina. Herbicida.
Produção e avaliação de fertilizantes fosfatados enriquecidos com Trichoderma harzianum: efeitos no crescimento inicial de plantas de milho
Authors:   , Oliveira Hend Pereira
Published: August 2022

O fósforo (P) é um dos nutrientes mais limitantes ao crescimento de plantas em solos tropicais. A aplicação de fertilizantes fosfatados é uma prática fundamental para a reposição de P ao solo visando aumentar sua disponibilidade para as culturas agrícolas. Esforços contínuos para melhorar a eficiência de uso de fertilizantes fosfatados são também essenciais para garantir a sustentabilidade da produção de alimentos, fibras, madeira e energia nessas áreas. Uma estratégia promissora para o aumento da eficiência da adubação fosfatada é o uso de microrganismos solubilizadores de fosfato (MSF). Muitos desses organismos podem ser utilizados para aumentar a disponibilidade de P no solo, bem como sua aquisição pelas plantas, dentre outros efeitos benéficos. No presente estudo foram produzidos fertilizantes fosfatados enriquecidos ou não com o fungo Trichoderma harzianum. No primeiro capítulo, diferentes concentrações do fungo foram adicionadas ao Fosfato Natural Reativo de Marrocos. No segundo capítulo, o fungo foi adicionado ao superfosfato triplo, com a presença e ausência de revestimento. A planta teste utilizada para avaliar as respostas dos fertilizantes produzidos foi o milho (Zea mays) cultivado em casa de vegetação. Ao fim dos experimentos, as plantas de milho foram avaliadas quanto ao seu crescimento (parte aérea e raízes) e conteúdo de P. Além disso, foram realizadas determinações de pH e da atividade de fosfatases (ácida e alcalina) no solo. O enriquecimento do fosfato natural reativo de Marrocos com Tricoderma harzianum proporcionou aumento no conteúdo de P e na matéria seca total das plantas em 33 e 21%, respectivamente, em relação ao tratamento controle (sem adição do fungo). A adição de Trichoderma harzianum ao superfosfato triplo também aumentou o conteúdo de P e crescimento inicial das plantas. A matéria seca total das plantas e o seu conteúdo de P aumentaram 25 e 56%, respectivamente, no tratamento que o fertilizante foi enriquecido com Trichoderma harzianum, comparativamente ao tratamento controle.Palavras-chave: Microrganismos solubilizadores de fosfato.

Espectrômetro de som para análise de componentes majoritários em matrizes líquidas
Authors:   , Zampier Lorrayne Moreira
Published: August 2022

As ondas acústicas ou sonoras são ondas mecânicas que dependem de um meio para se propagarem e a partir de algumas propriedades como a velocidade de propagação e atenuação torna-se possível realizar medidas desta propagação, sendo a temperatura um fator importante a ser considerado. O método baseado na propagação de ondas acústicas transferidas para o meio em estudo emprega sensores acústicos para detectá-las. Uma das vantagens está no fato de ser não destrutivo, com a possibilidade de ser não invasivo e usado em aplicações de linha. Assim, pode ser utilizado para análise de várias matrizes, como alimentos, sendo bastante utilizado na análise de líquidos. Neste trabalho foi construído um espectrômetro de som para análise de componentes majoritários em matrizes líquidas, utilizando-se como transdutores, elementos piezoelétricos para uma faixa de frequência de 100 Hz a 20 kHz. Foram desenvolvidas células de diferentes tamanhos e formatos. Observou-se a importância do controle da temperatura e da distância entre os elementos piezoelétricos. Em particular, quanto maior a distância, maior a atenuação observada enquanto, abaixo de 4 mm foi observado a sobreposição de bandas. Foi possível discriminar diferentes matrizes líquidas, tais como soluções puras de sacarose, etanol, lactose, ácido acético e soluções de leites (integral e zero lactose) com auxílio da análise de componentes principais. Com auxílio da regressão por quadrados mínimos parciais, foi possível a quantificação de sacarose, etanol e ácido acético em uma mistura destes, assim como a determinação de teor alcóolico em vinhos, com um erro relativo de -3,92 a 2,35% quando comparado ao método de referência e uma estimativa do desvio padrão dos resíduos igual a 0,012. O instrumento desenvolvimento mostrou-se eficaz, prático e robusto, além de apresentar um baixo custo relativo à sua montagem. Palavras-chave: Quimiometria. Detectores. Análise de Regressão.

Neste trabalho estão descritas as sínteses e caracterizações de 67 compostos derivados de sulfonamidas, sendo 32 inéditos, com potencial atividade antifúngico para o controle de doenças de plantas. A primeira etapa consistiu na síntese de 55 sais complexos de zinco com diferentes ligantes N-R-sulfonilditiocarbimatos derivados de sulfonamidas. Estes diânions foram isolados na forma de sais de amônio e fosfônio. Os sais foram caracterizados por espectroscopias no infravermelho, de ressonância magnética nuclear de 1 H e 13 C, por análises elementares. Também foram realizados estudos estruturais por difração de raio-X. Estes sais foram submetidos a ensaios biológicos para avaliação de sua atividade inibidora da germinação de Hemileia vastatrix, apresentando uma excelente atividade in vitro. Os mais ativos foram selecionados para testes in vivo e foram capazes de controlar o desenvolvimento da ferrugem do café, sendo um deles mais eficaz que o fungicida mancozeb na dose de 300 µmolL -1 . Estes mesmos sais foram submetidos a testes de inibição de crescimento micelial de fungos dos gêneros Botrytis e Rhizoctonia, in vitro, nas concentrações de 50 e 150 µmolL -1 , onde apresentaram boa atividade. O composto mais ativo foi submetido a testes de toxicidade com abelha (Apis mellifera) e foi verificada baixa toxicidade. A segunda etapa consistiu na síntese de alilsulfonamidas derivadas de adutos de Morita-Baylis-Hillman (MBH). Dois adutos MBH foram sintetizados através do acoplamento de um aldeído e alquenos contendo os grupos retiradores de elétrons CN e CO 2 CH 3 . Os adutos de MBH foram utilizados como intermediários para a obtenção de doze alilsulfonamidas por meio de reações com sulfonamidas primárias. As alilsulfonamidas foram totalmente caracterizadas por métodos espectroscópicos. Estudos por difração de Raios-X confirmaram a estereoquímica E para alilsulfonamidas contendo um grupo éster, e Z quando possuem o grupo ciano. Testes in vitro mostraram que as alilsulfonamidas apresentam uma ação antifúngica moderada, inibindo o crescimento micelial de B. cinerea.Palavras-chave: Alilsulfonamida. Ditiocarbimato de zinco.

The maximum sorption of tannin by diatomaceous earth was 58.4 mg per 1 g of sorbent. The combined material based on diatomaceous earth and chitosan absorbs 147.2 mg of tannin per 1 g of sorbent. Chitosan and the combined sorbent have the best sorbing properties in relation to polyphenols. Research in this area will solve the problem of colloidal turbidity, increase the shelf life and sale of finished fermented drinks and beer.

Researches of the main economically valuable traits of Belarusian varieties of oil flax - Brest, Ilim, Opus, Salyut, Focus were carried out. It has been established that the total infection of flax seeds with a complex of pathogens does not exceed 27.2%, field germination by varieties on average over the years of testing was 81.8%-87.1%, plant survival 79.6-83.3%. The maximum productivity of seeds of the presented varieties and the oil content in them were studied, the analysis of the crop structure was carried out. The fatty acid composition of linseed oil, the content of omega-3 α-linolenic acid, tocopherols, carotenoids, coenzyme Q10, and phytosterols have been studied. It has been established that the oxidative stability of the studied samples of linseed oil decreases with an increase in the content of α-linolenic acid. To ensure effective antioxidant protection of specialized food products based on linseed oil, stabilizers based on fat-soluble derivatives of ascorbic acid were used, which make it possible to significantly inhibit the processes of oxidation and oxidative degradation of polyunsaturated fatty acids. Based on the results obtained, formulations and technologies for obtaining two specialized food products based on linseed oil have been developed.

One of the main trends in the consumer food market is the growth in the consumption of plantbased products. A large share is made up of drinks, often called vegetable «milk». These lactose-free drinks are a substitute for traditional cow's milk and are becoming an increasingly popular consumer product as many consumers are lactose-intolerant, dieting or health-conscious. The article presents the results of a scoring of the quality of nine samples of vegetable drinks from retail outlets in Minsk. As a result of the work carried out by the commission of tasters-evaluators, indicators of consumer properties of new types of herbal drinks were developed. On the basis of marketing research, consumer preferences have been studied and coefficients of significance of indicators for assessing the quality of drinks have been determined. Using the developed scoring scale, the quality of nine samples of herbal drinks was assessed, as a result of which a sample was determined that scored the maximum number of points and can be chosen as the base one when determining the quality level.

Published: August 2022

Scientometric indicators are nowadays an almost mandatory element in assessing the scientific activity of a scientist or an academic organization, and scientometric methods are actively used in various studies in the field of science studies, including bibliometric studies. The article analyses the three largest citation systems. The Belarusian publications on agriculture selected from Web of Science, Scopus and RSCI scientometric databases for the period 1991-2021 have been studied in detail. Articles were analyzed by subject, publishing organizations, authors, year of publication, types of publications, and other parameters. Based on the results obtained, it was concluded that the number of publications and the number of their citations is growing every year. This indicates the growing publication activity of the authors. However, Belarusian authors prefer to publish in Russian-language editions that are not included articlein foreign information resources. This indicates the need for their further promotion in the world information systems. At the same time, the reflection of publications with the participation of Belarusian authors in international information resources undoubtedly has a positive effect on the status of national science in the system of global scientific communications.
Methodological approaches to creating a Russian-language version of the AGROVOC thesaurus
Authors: Pirumova Lidia N.
Published: August 2022

The article considers the methodological principles used in the creation of the Russian-language version of AGROVOC, the multilingual thesaurus of the international information system for agriculture and food of the UN FAO AGRIS. The stages and content of the works on the creation of the Russian version are considered. The results of the work done are presented: studying the lexical composition of the AGROVOC thesaurus; comparative analysis of approaches to assigning the status of a term in the dictionary entries of national thesauri; researching in solving issues of lexical polysemanticism and disambiguate in the AGROVOC thesaurus; analysis of the meaning of synonymy relations; studying the functions of the “Note” field. When creating the Russian-language version, the methodology of translating terms directly by agricultural specialists was used, ensuring thereby a high-quality selection of equivalents to English terms of the English-language version of the thesaurus and with the minimal revision needed. The work started with finding equivalents for the descriptors, then proceeded to translating synonyms. Word combinations and relators were used to eliminate lexical polysemanticism and disambiguate of terms. When selecting an equivalent to an English AGROVOC term, the developers of the Russian-language version were guided by the following basic rules: the undesirability of literal translation; the differentiation of concepts and the use of relators to emendate terms; artificial formation of equivalents when accurate translation was impossible. For precise selection of the Russian equivalent of a term of the thesaurus we analysed all its relationships with the other terms -broader and narrower, synonyms, associated terms, as well as the text of notes, which could indicate limitations of the scope of use of the term, emendation of a concept, etc.

Accurate knowledge of soil fertility is required to promote global food security for life sustenance. Literatures have shown that electrical resistivity method is effective for agricultural site selection without passing through the rigor of soil test. However, the factor responsible for inconsistence in resistivity signature with soil fertility from one place to another, effect of soil texture and depth variation on crop yield are the questions this work geared at providing answers. Ten Vertical Electrical Sounding (VES) were conducted across the study area using Schlumberger array. Res1Dinvers was used for the inversion model, using Least Square method. Twenty soil samples were obtained in the VES points, two samples per point. One sample each at first and second layer. Result of the apparent resistivity showed that areas with high-excellent crop yield have resistivity signature above 500 Ωm while areas with low yield are characterized by values less than 500 Ωm. In both areas of low and high-excellent crop yield, the result of geochemical analysis indicated that Nitrogen, phosphate, and Potassium varied as 59-61%, 43-54mg/kg and 49-51mg/kg, respectively except for organic matter content that was above 3.8% in the first layer have high-excellent yield while low yield soil showed less than 3.8% in their first layer and even if the second layer’s organic matter is above 3.8%. This study has shown that organic matter has significant effect on soil resistivity signature than others soil nutrients (Phosphate, Potassium and Nitrogen). The study shows that soil’s first layer (0-0.3m) is the most suitable depth conducive for soil minerals occurrence for optimum agricultural output.

A major population of youth is increasingly engaging in law violation activities which has become a matter of concern all over the world. The need of the hour calls for a rehabilitation programme designed to cater to the needs and deficits of conflict with law. Keeping this view in mind, a Skill Based Intervention Programme (SBIP) has been developed for CCL. The SBIP consisted of two sets of modules of group sessions: Direct Application of Psychological Principles and Application of Psychological Principles using Music and there was also another module for Individual Psychological sessions. Post the development of the Intervention Programme, the SBIP was conducted on 93 males within the age range 12-17 years. Pre-post intervention data was collected using the Adaptive Behaviour Checklist for CCL, specially developed to meet the requirements of the module. Data for Pre-intervention assessment was collected from 93 males. However, data for post assessment intervention could be collected only from 59 adolescents who participated in the entire Intervention programme. Results indicated significant differences between the pre-intervention and the post-intervention scores, the post-intervention scores significantly higher than the pre-intervention score. Change processes have been enumerated in the discussion.
