title: ANALYSIS OF BENZODIAZEPINES IN PLASMA SAMPLES BY DLLME AND LC-DAD: CRITICAL ASPECTS, FLAWS AND ISSUES ENCOUNTERED - A DISCUSSION

description: Dispersive liquid-liquid microextraction (DLLME) is a fast and simple technique and applicable procedure for the analysis of xenobiotics in different biological matrices. We have developed a DLLME method for the determination of benzodiazepines in plasma samples using liquid chromatography-diode-array detection (LC-DAD). During method validation, relative standard deviation values of more than 20% were observed for both intra and inter-day associated with precision and accuracy. So, full method validation was unsuccessful. Critical aspects and flaws associated with DLLME for benzodiazepines determination in biological matrices has never been addressed. The majority of previous studies involving DLLME for benzodiazepines analysis either did not carry out a full method validation or they do not share any details regarding their full validation procedure. The current study has focused on the issues and pitfalls encountered upon method validation so that scientific groups worldwide can avoid unnecessary experiments and benefit from the present discussion. These observations reinforce the need to carry out such a process to guarantee the reliability of the results, even more so if one is intending its application for real case samples in the field of toxicological analysis. Indeed, full, and satisfactory method validation is paramount to provide adequate and trustworthy analytical results.

title: CHLOROPHYLL EXTRACTED FROM INDUSTRIAL WASTE FROM MATE-HERB (Ilex paraguaiensis) A POSSIBILITY OF CIRCULAR ECONOMY.

description: Chlorophyll is the most abundant green pigment on the planet, it is unstable and decomposes naturally. Mate-herb is a traditional native plant in the southern region of South America, and its tea is part of the local culture and extractive agriculture. The mate-herb industry generates as a by-product a resinous material rich in chlorophyll whose use is proposed to be a natural pigment. The chlorophyll extraction method uses ethanol as a solvent; its structural modification leads to the obtainment of derivatives like pheophytin, Co-pheophytin, Ni-pheophytin, and Zn-pheophytin. The samples were analyzed by electronic (VISIBLE) and vibrational (FTIR) spectroscopy, and energy-dispersive X-ray fluorescence spectrometry (EDXRF). Color analysis (CIE L*a*b*) was performed by decomposition in grayscale and the classification of the samples by the supervised machine learning (ML) algorithm Random Forest (RF), showing adequate accuracy for this type of matrix. The pigments were dispersed in synthetic enamel paint to study color stability when exposed to lighting. It was verified that Co-pheophytin and Ni-pheophytin are the most stable. The chlorophyll extracted from the resin presents an economically viable use for residues from mate-herb industries, whose family farmers benefit, with the bias of environmental and social sustainability, within the circular economy.

title: Validity evidence of the Academic Procrastination Scale for undergraduates

description: Abstract The objective of this study is to analyze the validity evidence of the Academic Procrastination Scale (APS) in a sample consisting of 1979 students from public and private universities, from different courses, 67% of the students being women, aged 18 to 68 years old (M = 22.84). The principal component analysis revealed two components, also validated by confirmatory analysis, which showed a good overall fit of a two-dimensional model: Daily Study Procrastination (a = 0.75) and Exam Study Procrastination (a = 0.75). Internal consistency was estimated through Cronbach’s alpha, obtaining 0.83 for the total scale. The study concludes that APS has satisfactory psychometric properties and suggests further validation studies and also analysis of academic procrastination in higher education students.

title: The application and benefits of digital technologies for agri-food value chain: Evidence from an emerging country

description: ABSTRACT Purpose: Many academic and technical studies have explored information and communications technology (ICT) applications in the agri-food sector from the farmers’ perspective. However, the technology supplier perspective on the ICT application has been largely overlooked. This paper aims to analyze how digital technologies are used within the agri-food value chain and their benefits and advantages from the technology supplier perspective. Originality/value: First, the study analyzed the benefits of ICT for the agri-food sector from the technology supplier perspective. Second, it comprised the integrated analysis of the complete set of ICT applied to the entire agri-food value chain. Third, we guaranteed the study’s replicability by using a straightforward methodological approach. Design/methodology/approach: Exploratory study with a descriptive approach was employed to map the complete set of digital technologies commercialized by 131 agri-food technology companies. The Organisation for Economic Co-operation and Development’s (OECD) (2018) typology for ICT solutions was used to identify technology types. The NVIVO software cluster analysis was applied to the data related to the benefits and advantages of the firms’ ICT solutions. Findings: We identified that cost reduction and rapid decision-making are the essential benefits of ICT. It was found that the ICT field in the agri-food sector is composed of different companies’ generations, and many are not startups. We identified two new phenomena: agricultural servitization, which comprehends the increasing importance of services as crucial input for agricultural production, and agricultural manufacturing, which refers to increasing control over production factors in agriculture.

title: ARTEMISININ AND DERIVATIVES: DISCOVERY, SYNTHETIC STRATEGIES, AND INDUSTRIAL PRODUCTION

description: Artemisinin, a natural sesquiterpene isolated from the Artemisia annua L. plant, represents a remarkable achievement in the treatment against malaria. Since its discovery in the 1970’s, researchers readily started synthesizing this complex natural product containing an unusual endoperoxide fragment. Despite various total syntheses reported, only in the last decade the production jumped from extraction/bench scale to industrial manufacturing. In this sense, the objective of this contribution is to highlight the discovery, the most representative works towards the synthesis of artemisinin and its main derivatives used worldwide against malaria, and the path to the industrial production of these compounds.

title: Treatment of swine wastewater in a biological system for disposal in a sandy soil

description: ABSTRACT This work aimed to evaluate the efficiency of a system composed of a UASB reactor followed by post-treatment with an aerobic granular sludge reactor (AGS) in the treatment of swine wastewater (SW) for disposal in sandy soil. The characteristics of the treated effluent and the soil from a disposal site were evaluated, as well as the parameters of mobility of contaminants such as dispersion coefficient (D), dispersivity (λ), delay factor (R), and Péclet number (Pe) were determined. Treated SW was percolated in a permanent flow regime in columns of saturated soil. Elution curves (breakthrough curves) were generated, obtaining the transport parameters by adjusting the solute transport equation in the soil. The soil used was characterized as a quartzene soil with a sandy texture. It was observed that, although the treatment presents high removal efficiencies for COD, BOD, TSS, nitrogen, and phosphorus, the treated SW still did not meet some parameters for surface water discharge or soil disposal based in current legislation. Except for phosphate and potassium, ions showed a tendency to move in the soil and to contaminate the groundwater.

title: Psychometric validation of the audio-guided rBVQ instrument for bullying evaluation among students

description: Abstract The revised Olweus Bully/Victim Questionnaire (rBVQ) is an internationally used instrument to identify bullying, but due to Brazilian students’ low proficiency in reading and writing, it had to be adapted for audio-guided use through smartphones. We investigated construct validity, using Confirmatory Factor Analysis (CFA), under a two-correlated factor solution. Participated 1,742 fifth graders and 2,316 seventh graders from 30 public schools in the city of São Paulo. We found excellent fit indices models for both grades (fifth grade: CFI=0.985, RMSEA=0.020; seventh grade: CFI=0.990, RMSEA=0.015), as well as factor loading higher than 0.4 for all items, indicating their relevance to the construct. The rBVQ demonstrated excellent psychometric properties and may help future studies that aim to investigate bullying in populations with similar profiles. In addition, this study innovates by evaluating an audio-guided instrument and using mobile technology.

title: Use of the tax benefit of conventional remuneration of share capital by Portuguese companies

description: ABSTRACT This article aimed to analyze the use of the tax benefit of conventional remuneration of share capital (CRSC) by Portuguese companies and perceive the influence of tax policies on their financing decisions. Most of the studies are based on the relationship between financing through debt capital and taxation, in which evidence is found that tax benefits influence the capital structure of companies. There is a lack of studies in Portuguese companies. The article is relevant as it adds the increase in capital variable, because in some countries, particularly Portugal, there are also tax incentives through the own-capital financing route. Thus, this investigation provides results of Portuguese companies choosing own-capital financing before and after tax changes that incentivize its use. The empirical study was conducted through a survey questionnaire, using a sample composed of 324 Portuguese companies with economic activity. The article contributes to the study of the relationship between own-capital financing and the existing tax law in Portugal. The tax benefit of CRSC has not been enough for companies to alter their financing policy when they have to choose between resorting to debt capital and injecting new funds through capital holders. However, this incentive has led to a reduction in debt capital, through its conversion into capital, and an increase in capital through the incorporation of earnings generated, with both these practices potentially representing tax planning opportunities. Despite there being the perception that the acceptance of interest as a tax expense favors company financing through debt capital, there is recognition that this benefit incentivizes the capitalization of companies and their financing through own capital, as an alternative to debt capital, especially in medium-sized companies.
