Furthermore, the increase in the cost of synthetic fertilizers makes the use of organic matter in soils viable. Therefore, the objective of this study was to evaluate the use of multivariate statistics through the analysis of the main components in the contents of chemical elements in two layers of soil in a bean cultivation cycle and to determine the possible correlations of the variables with the respective treatments. Biochar was made from sewage sludge. Cultivation was carried out under rainfed conditions. The treatments used were NPK = synthetic fertilizer; B5 = Biochar 5 t ha-1; B10 = Biochar 10 t ha-1; B20 = Biochar 20 t ha-1; B40 = Biochar 40 t ha-1; CM = chicken manure 5 t ha-1; and SS = Sewage sludge 5 t ha-1. In the 0-0.1 m layer, PC1 explained 71.82% of the data variability, influenced by K, P, Mg, SO42-, TOC and N, while PC2 influenced salinity and acidity. Biochar, at doses of 20 and 40 t ha-1, improved nutrient availability. In the 0.1-0.2 m layer, PC1 explained 84.39% of the variability, with contributions from all variables, while PC2 influenced the Mg concentration. Therefore, the application of biochar is a sustainable and promising practice to increase productivity in the Agreste of Pernambuco.","PeriodicalId":506304,"journal":{"name":"Scientia Plena","volume":" 22","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141826092","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aimed to investigate the effects of blanching time and temperature on three commercial mushroom varieties' lightness and color variation and determine the optimal operation conditions. Three specimens were collected: Agaricus bisporus Paris Champignon, Agaricus bisporus Portobello, and Lentinula edodes Shiitake. The composite central rotational design and the response surface methodology were employed to evaluate the combined effects of blanching temperature (ranging from 53.8°C to 96.2°C) and time (ranging from 10.3 seconds to 349.7 seconds) on the color parameters L* (lightness), a* (redness-greenness) and b* (yellowness-blueness) of mushrooms slices. Cutting, oxygen exposure, and temperature below 75°C significantly affected the color by reducing L* and b* values and increasing a* values, favoring the mushrooms' darkening (higher △L). The bleaching operation optimized to minimize color variation (△E) was at 80°C for 170 seconds for Champignon, 83°C for 209 seconds for Portobello, and 82°C for 186 seconds for Shitake. Blanching fresh mushrooms under these operational conditions can help prevent the development of dark color, thereby improving their quality for human consumption, extending their shelf life, and reducing waste caused by unsightly appearance.","PeriodicalId":506304,"journal":{"name":"Scientia Plena","volume":" 23","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141825857","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this context, the objective of this study was to analyse the data from the notifications of the Panel of Surveillance on Health of Populations Exposed to Pesticides (VSPEA) by the Ministry of Health for the State of Paraíba, in the historical series from 2007 to 2022. The analysis included the incidence rate; prioritized municipalities for the implementation of surveillance programs; distribution of notifications by gender, age group, exposure location, circumstance, and type of agent. Paraíba has accumulated 2,793 notifications of exogenous intoxication by pesticides. Regarding gender and age group, there is a slight predominance in notifications for women (50.18%), with higher numbers for men aged 40 and older, and for women in the 10 to 29 age group. The vast majority of intoxications occur in homes (74.83%), as a result of suicide attempts (57.50%), with rodenticides being the most common agents (50.30%). Currently, there are 1,316 pesticides approved for commercialization and use in the state, with the majority classified as highly toxic products. It can be concluded that the significant number of notifications indicates that health units are effectively contributing to the systems, and/or cases of intoxication are increasing indiscriminately, mainly due to the easy acquisition of rodenticides. It is important to emphasize that VSPEA is an essential tool for the development and promotion of public policies against pesticide intoxication.","PeriodicalId":506304,"journal":{"name":"Scientia Plena","volume":" 27","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141827739","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The phytochemical aspects of guarana have been extensively explored for its use in herbal and cosmetic compositions due to the presence of metabolites, such as methylxanthines and polyphenols. This work aims to fill a gap in the information about the presence and accumulation of methylxanthines and polyphenols in leaves and fruits of guarana cultivars. Thus, information will be generated to contribute for future studies on guarana genetic improvement and plant physiology. Methylxanthines (caffeine [Cf], theobromine [Tb], and theophylline [Tf]) and phenolic compounds (catechin [Ct] and epicatechin [EC]) were quantified by HPLC in the leaves and fruits (pericarp and seed) of eighteen guarana cultivars. Tf was not detected in any tissue. Caffeine is present almost exclusively in seeds (4.21 ± 0.69 g.100g dry weight-1), while theobromine is predominant in leaves. Although catechin and epicatechin are present in both tissues, their contents are higher in seeds, with mean values of 1.36 and 0.76 g.100g dry weight-1, respectively. In guarana cultivars under study, BRS-Satere and BRS-608 stood out due to the high caffeine and phenolic contents in seeds. On the other hand, in BRS-Luzeia cultivar, the highest catechin and epicatechin contents were observed in leaves. The results provide new perspectives for the commercial exploitation of other guarana tissues, which could favor the industry, since the main source of these compounds are guarana seeds.","PeriodicalId":506304,"journal":{"name":"Scientia Plena","volume":" 24","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141826855","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

After selecting the formulation with the required characteristics, OECC was added and the blend was characterized by pH, spreadability, viscosity, rheology, and chemical analysis. Chitosan, a polymer defined by the design, provided the formation of the gelled blend in a shorter time and the absence of precipitates. The presence of OECC allows for discreet changes in chemical properties (in the infrared spectrum, displacement of the C=C peak of the oil in the blend; in pH, a slight increase to 4.6); but not in the rheological ones, only a reduction in spreadability and maintenance of the pseudoplastic behavior of the blend without the OECC.

A few true fly (Diptera) species use chemical defenses and among the adult ones, these mechanisms have only been formally registered in the family Sepsidae. Some species of this family possess an abdominal gland (Dufour gland) that produces a substance with a characteristic and intense odor. This odor supposedly turns the sepsids unpalatable to their predators. However, there is no study testing this hypothesis with Neotropical species yet. Thus, the aim of this study is to verify if two neotropical species of Sepsidae (Archisepsis armata and Microsepsis armillata) are unpalatable to invertebrate predators (jumping spiders, giant crab spiders, and mantises). The experiment consisted in offering specimens of sepsids (treatment group) and fruit flies (drosophilids; control group) to three species of predators. Furthermore, a study of the internal morphology of the two sepsid species has been performed to verify the presence of the Dufour gland. There has not been any significant predation difference between the sepsids and the control group, and the Dufour gland has not been found in both of them. This data suggests that both neotropical species of sepsids are not unpalatable.","PeriodicalId":506304,"journal":{"name":"Scientia Plena","volume":" 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141826994","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
