In recent years, technological development in analytical instrumentation has progressed vigorously, which has allowed the evolution of analytical techniques that play an indispensable role within society, highlighting mass spectrometry. Parallel to the technological advance of this technique, the development of new ionization methods that are simpler, faster, and allow direct analysis without the need for prior treatment or sample processing is underway. The methods of ambient ionization derived from paper spray have been developing rapidly in current days, mainly in the forensic field, due to the chemical modifications made in the paper substrate and the introduction of new types of organic materials that function as a probe/substrate to collect, store, and ionize the sample, then enabling more efficient and selective analyzes. This review highlights direct analyzes by applying paper spray ionization in the forensic field and some variations of this technique, including Thread Spray Ionization (TSI) when a fabric thread is used; Touch Spray Ionization (TSI), which uses materials such as metallic needles, medical swabs, and wooden sticks; Fiber Spray Ionization (FSI), which applies polymeric fibers as substrates.

Este artigo tem por objetivo identificar os fatores que têm afetado as receitas das exportações de celulose e papel e papelão, no período de 2001 a 2020. Especificamente pretende-se quantificar as variações nas receitas provenientes da taxa de câmbio, do preço internacional e da quantidade exportada de celulose e de papel e papelão e identificar os principais eventos associados essas variações. Para tanto, utilizou-se o método diferencial-estrutural, conhecido como shift-share, que decompõe as variações da receita de exportação em efeitos parciais proporcionado por outras variáveis relacionadas. Os resultados mostram que mesmo quando os efeitos do preço internacional e a taxa de câmbio são desfavoráveis a quantidade exportada de celulose e de papel e papelão tem sido crescente, e proporcionando efeito total positivo nas receitas das exportações. Somente em quatro grandes momentos houve queda nas receitas das exportações destes produtos, momentos estes que coincidem com a ocorrência das seguintes crises: atentado a torres gêmeas (2002), crise do subprime (2008), crise política interna (2016) e pandemia (Covid-2019). ABSTRACT: This paper aims to identify the factors that have affected revenues from pulp and paper and paperboard exports, in the period from 2001 to 2020. Specifically, it intends to quantify the variations in revenues arising from the exchange rate, the international price and the exported quantity of Wood pulp and paperbord and identify the main events associate these variations. For this purpose, the differential-structural method, known as shift-share, was used, which breaks down changes in export revenue into partial effects provided by other related variables. The results show that even when the effects of the international price and the exchange rate are unfavorable, the exported quantity of woodpulp and paperboard has been increasing, providing a positive overall effect on export revenues. Only in four major moments were there decreases in revenues from exports of these products, moments that coincide with the occurrence of the following crises: attack on the twin towers (2002), subprime crisis (2008), internal political crisis (2016) and pandemic (Covid- 2019).

Esse texto discute a formação do espaço econômico paranaense e sua relação com as atividades de base econômica ou exportação. A análise segue uma visão institucionalista a partir da teorização de Douglass North. A análise também se embasa em Pedro Calil Padis, por fazer um retrospecto eficaz dos primórdios do Paraná até o final dos anos 1960. Se parte do princípio de que várias economias regionais que surgiram no Brasil estavam em condições periféricas. O termo “periférico” é devido ao fato de a economia de cada uma dessas regiões ou Estados estar subordinada ao centro dinâmico do país devido a vários fatores, dentre eles a transferência de capital, fazendo com que o Paraná, com sua economia cafeeira, subsidiasse a indústria paulista. Abstract: This paper discusses the formation of the economic space of Paraná State and its relationship with economic-based activities or exports. The analysis follows an institutionalist vision based on Douglass North's theorization. The analysis is also based on Pedro Calil Padis, for making an effective retrospective of the beginnings of Paraná State until the end of the 1960s. It is based on the principle that several regional economies that emerged in Brazil were in peripheral conditions. The term “peripheral” is since the economy of each of these regions or states is subordinated to the dynamic center of the country due to several factors, including the transfer of capital, causing Paraná, with its coffee economy, to subsidize the São Paulo industry.

In the criminal sphere, it is extremely important to identify perpetrators of crimes based on latent fingerprints (invisible to the naked eye) revealed at crime scenes and their corresponding objects. The present work aimed to evaluate four synthetic analogues of curcumin as possible IDL developers, and to compare their results with those of carbon black developer, as well as to reach the most adequate parameters in the use of the LTQ and FT-ICR mass spectrometers with the paper spray ionization (PS) source to study the chemical composition of the endogenous substances contained in the IDL. For this, a 24-1 factorial design was developed, where it was verified that the distance and voltage factors were the most influential for the increase in the response of signals, in the analysis of latent fingerprints by PS. Among the detected substances we can mention around 20 fatty acids, and squalene. Finally, four potential developers, synthetic analogues of curcumin, were compared with carbon black developer. The revelation of latent fingerprints occurred efficiently, allowing the visualization of minutiae, such as bifurcation and end of line, making it possible to classify them, according to the Vucetich Fingerprint Classification System.

As práticas pedagógicas centradas em videojogos têm vindo a tornar-se cada vez mais populares, dado oferecerem vantagens empiricamente validadas no que diz respeito ao envolvimento dos alunos, à sua motivação e sentido de agência. Estes construtos afetivos são agora reconhecidos como componentes-chave de uma aprendizagem eficaz e significativa, favorecendo o desenvolvimento de competências cognitivas de nível superior. Contudo, enquanto se atesta um número elevado de estudos sobre o uso de videojogos educativos nas áreas das Ciências, Tecnologia, Engenharia e Matemática (STEM), é necessário ainda explorar as potencialidades desses recursos nas disciplinas de Humanidades. Analogamente, devem ser empreendidos mais esforços no sentido da investigação e implementação de atividades que atribuam aos alunos, especialmente àqueles de níveis inferiores ao do Ensino Superior, o papel de designers de videojogos, aliado ao de jogadores. Desta feita, criam-se as condições para que os alunos construam material didático autêntico, sob a forma de experiências digitais imersivas, que apresentam tanto um valor educacional como de entretenimento. Assim, este artigo funciona como um Position Paper sobre a Aprendizagem Baseada em Jogos Digitais ou Digital Game-based learning (DGBL), descrevendo as vantagens afetivas de se jogar e criar videojogos educativos na sala de aula de Humanidades, enquanto reflete criticamente sobre possíveis obstáculos ao sucesso desta prática. O nosso objetivo é estudar como a tecnologia educativa e imersiva pode satisfazer as necessidades de aprendizagem da Geração Z, tendo em consideração os diferentes fatores contextuais que definem o seu perfil.

Abstract Objective The purpose of the present study is to standardize and evaluate the use of the immunoglobulin G (IgG) antibody avidity test on blood samples from newborns collected on filter paper to perform the heel test aiming at its implementation in ongoing programs. Methods Blood samples from newborns were collected on filter paper simultaneously with the heel prick test. All samples were subjected to immunoglobulin M IgM and IgG enzyme-linked immunosorbent assays (ELISA). Peripheral blood was collected again in the traditional way and on filter paper from newborns with high IgG levels (33). Three types of techniques were performed, the standard for measuring IgG in serum, adapted for filter paper and the technique of IgG avidity in serum and on filter paper. The results of the avidity test were classified according to the Rahbari protocol. Results Among the 177 samples, 17 were collected in duplicate from the same child, 1 of peripheral blood and 1 on filter paper. In this analysis, 1 (5.88%) of the 17 samples collected in duplicate also exhibited low IgG avidity, suggesting congenital infection. In addition, the results obtained from serum and filter paper were in agreement, that is, 16 (94.12%) samples presented high avidity, with 100% agreement between the results obtained from serum and from filter paper. Conclusion The results of the present study indicate that the avidity test may be another valuable method for the diagnosis of congenital toxoplasmosis in newborns.

In this paper, we estimated the methane emissions by the disposal of sanitary and domestic-use paper consumed throughout Brazil from 1901 to 2016. The apparent consumption of this type of paper from 1961 to 2016, calculated from the data of the FAOSTAT system, was used to estimate the amount of waste disposed of annually in three site categories: sanitary landfill, controlled dump, and open-air, uncontrolled dump. The 2006 IPCC Guide methodology was used to calculate CH4emissions and long-term carbon storage. Nine scenarios based upon the law that establishes the National Solid Waste Policy (NSWP) were examined, considering 100% waste disposal and treatment in landfills or incineration from 2014. The total emission was estimated at 1.967 MtCH4, corresponding to 55.080 MtCO2eq by GWP-AR5, and the stored carbon at 3.724 Mt, corresponding to 13.655 MtCO2eq. CH4emission increased beyond the population growth rate due to an increase in the per capita paper consumption in the country, from 0.02 kgCH4.year-1 in 1961 to 0.30 kg CH4.year-1 in 2016. The NSWP has not yet been accomplished, and the scenarios outlined indicate that, from the point of view of CH4 emissions, it would be more advantageous to carry out incineration instead of applying other waste treatment technologies.
