AbstractFor the sustainability of the construction industry, geopolymers (GPMs) play an important role compared with Portland cement due to their improved mechanical properties, enhanced durability, and outstanding performance in alkali and acidic conditions. Most of the previous review investigations explored the general behavior of GPM developed with kaolin, silica fume (SF), rice husk ash, ground granulated blast furnace slag, fly ash,etc., but a comprehensive review study on the industrial by-products, including granite waste powder (GWP) and bauxite residue (BR), is required to investigate their suitability in the construction industry. The current investigation aims to present a detailed review of the fresh, mechanical, durability, and microstructural behavior of the GPM paste produced using BR and GWP from the literature. The effect of different ingredients and testing conditions are evaluated for the fresh, mechanical, durability, thermal, and microstructural performance of the GPM paste. The results indicate that the pure BR having a lower ratio of SiO2/Al2O3reacts poorly; therefore, it should be blended with other aluminosilicates comprising a higher ratio of SiO2/Al2O3for better geopolymerization. Pre-activation of BR including 3 h calcination at 800°C, 1 h thermal pretreatment of alkali with solid activators at 800°C, mechanical co-grinding, and pulverization presented improved strength and microstructural properties of GPM. When mixing GWP in large quantities, heat curing is preferred for 8 h at 60–80°C for better behavior of GPM. Incorporating the nanomaterials into GWP-based GPM showed a significant impact on initial compressive and tensile strengths. Further studies on the synergistic use of GWP with aluminosilicate products and BR with silica-rich pozzolanic ingredients for GPM are required. Improved physiochemical features of BR-GPM and GWP-GPM are the potential research areas that can be addressed by incorporating raw materials for enhancing the internal matrix, such as nanoparticles, bio-additives, micro-fibers,etc., that have been observed to be effective for the GPM pastes.
Medeek medve, az óriás kiköpött foga és a mézevő elfelejtett dala: metrika, szemantika és adaptációs környezet az információk megőrzésében és elvesztésében
Authors: Z. Karvalics László 
Published: April 2023

A tanulmány az alábbi kutatói kérdésekre keresi a választ: mitől függ, hogy meddig él egy információ? Képesek vagyunk-e olyan peremfeltéteket (tér, idő, népességszám) azonosítani, amelyek megléte segíti a túlélést, és révükön definiálni tudjuk az információvesztést magyarázó tényezőket is? Találunk-e univerzális mintázatokat a különböző kultúrák által őrzött és újratermelt különböző típusú információk életciklusaiban?
Miután számos különleges példát tekintünk át információk egészen hosszú ideig tartó megőrzésére, de gyors elvesztésére is, már levonhatónak tűnik néhány fontos következtetés. Léteznek ugyan mérésműveleteknek értelmet adó helyzetek, de a legtöbb esetben csak valószínűségi kalkulációkkal számolhatunk. Ám ezen felül alapvetően meghatározóak az őrzött/elvesztett információk jelentéstípusai, valamint az ezekre a jelentésekre vonatkozó járulékos mentális tartalmak, amelyek kulturális kódként a változásokhoz való alkalmazkodást segítik. Királyi út és könnyű képlet tehát nincs, de a tárgykör kutatása még sokat izgalmat rejt magában.
Requiem a közgazdasági szaktájékoztatásért
Authors: Schiffler Kitti 
Published: April 2023

A Pécsi Tudományegyetem Egyetemi Könyvtár és Tudásközpont főigazgatósága évente egy alkalommal támogatja kutatási és/ vagy kreatív alkotási (elsősorban irodalmi) tevékenység folytatását a munkatársak számára. A Benedek Ferenc Jogtudományi és Közgazdaságtudományi Szakkönyvtárban régóta foglalkoztat minket a közgazdasági és jogi szaktájékoztatás országos helyzete, módszerei, formái, így a jogi szaktájékoztató kolléganőmmel elérkezettnek láttuk az időt egy átfogóbb felmérésre a nagyobb képzőhelyek könyvtárainak bevonásával. A téma aktualitását jelzi, hogy az egyetemi könyvtárak referensz szolgáltatásairól alig-alig jelenik meg magyar nyelvű publikáció, illetve tudomásunk szerint hasonló jellegű és volumenű kutatás hosszú idő óta nem történt Magyarországon. A kutatás során kevert típusú interjúkat készítettem két nagy képzőhely könyvtárának illetékes munkatársaival, melyek alapján egyértelműen megállapítható, hogy a hagyományos szaktájékoztatás szinte teljesen eltűnt a nagyobb hazai, közgazdaságtudományi képzést nyújtó egyetemek könyvtáraiból. Kijelenthetjük, hogy ezt a fajta szolgáltatást nagymértékben felváltották a célcsoportonkénti felhasználóképzés és kutatástámogatás személyes jelenlétet igénylő és online formái (pl. irodalomkutatási tréningek, adatbázishasználati kurzusok, Academic Writing). A vizsgált könyvtárak megoldásai és saját tapasztalataink nyomán egyértelművé vált, hogy mielőbb szükség van szolgáltatási portfóliónk felülvizsgálatára és hatékonyabb felhasználói igényekhez igazítására.
A könyvtár és az információkeresés által kiváltott szorongás: Mit tehet az iskolai könyvtár?
Authors: Arany-Nagy Zsuzsanna 
Published: April 2023

A 21. század társadalma a digitális átmenet tanújaként vonul be a történelembe. A változás eredményeként az információk – a hagyományos, nyomtatott megjelenés mellett – digitális formában, online térben válnak bárki számára elérhetővé.
Kutatásomban arra a kérdésre keresem a választ, miért mellőzi a 10-20 éves (5-13. évfolyamon tanuló) korosztály a könyvtárak használatát. Jelen tanulmány egy nagyobb projekt része. A témában végzett felmérés eredményeinek kiértékelése jelenleg is tart, ám a szakirodalom áttekintése alapján célom bemutatni a jelenséget, felhívva a figyelmet a könyvtár- és információkeresés által kiváltott szorongásra. A szorongás leküzdésére tett kísérletek hatékonyan járulnak hozzá a könyvtárak népszerűségének növekedéséhez is. Tanulmányomban célom bemutatni, az iskolai könyvtárak szerepét a könyvtár- és információkeresés által kiváltott szorongás leküzdésének érdekében.
A téma ugyan nem újszerű, de aktualitását mi sem bizonyítja jobban annál, mint hogy az 1980-as évek óta folyamatosan jelennek meg újabb és újabb irodalmak a témában.
A kutatás – az eredmények elemzésének – jelenlegi fázisában a könyvtár által kiváltott szorongás egyértelmű jelenlétét nem jelenthetjük ki. Az adatok további elemzése, a korrelációvizsgálatok és az így kapott eredmények vélhetőleg igazolják az általam felállított hipotézist.
“... protect me, Lord, from contempt, protect me from hatred, God”. When Words Express Contempt
Authors: Gałczyńska Alicja 
Published: April 2023

The article is devoted to the concept of contempt, understood as a feeling of disrespect and aversion and a sense of superiority towards someone towards whom our contempt is directed. It is an emotion of a social nature, winding up a spiral of hatred. Contempt presupposes the speaker’s superiority, who considers himself superior to the person/group of people he is speaking to. I treat the rhetoric of contempt as an element of verbal aggression, which is sometimes expressed through various linguistic means. Here I would like to show how words change their meaning and start to express contempt and hatred towards another human being. Referring to the determinants of hate speech indicated by Michał Głowiński (ruthlessness of reason, objectification of the „hero” of the statement, dichotomy of values, conspiracy view of reality, arbitrariness of assessments and depersonalized sender), I indicate why the use of the term LGBT ideology is such an immoral way of using language. Language analyses focus on statements from public discourse – they were taken primarily from Internet portals and social media.
Fluxos migratórios para a Arábia Saudita
Authors: Seadi Pereira Catharina , Honório Horn Thais 
Published: April 2023

O presente artigo visa explorar a relação entre os fluxos migratórios com destino à Arábia Saudita e a economia do petróleo, da qual o país é profundamente dependente. Para isso, este trabalho analisa brevemente argumentações de alguns estudiosos clássicos da sociologia, como Malthus e Weber, e de alguns autores da economia neoclássica – trazidas por Sasaki e Assis (2000). Os esforços sumarizadores de D. B. Grigg (1977) acerca dos escritos de E. G. Ravenstein são abordados, também. Por último, a pesquisa faz uso das teorias migratórias apresentadas por Boswell (2002) que, complementando os argumentos anteriores, são utilizados para analisar dados oficiais da Organização Internacional para Migrações, por exemplo. Para atingir seu objetivo, é explorada a relação do Estado em questão com a exploração petrolífera e a relação que estes dois fatores têm com o trabalho de migrantes, sendo esta lógica inserida dentro do referencial teórico selecionado. Dessa forma, corrobora-se a hipótese estabelecida ao concluir que, em que pese mais pesquisas precisam ser realizadas, a relação existente entre os dois objetos de pesquisa é de lógica causal: os altos fluxos migratórios com destino à Arábia Saudita ocorrem em função do sucesso da indústria petrolífera no país.
Análise da temática migratória no contexto de integração regional dos países do Mercosul
Authors: Todeschini Caroline 
Published: April 2023

O objetivo da presente pesquisa foi analisar se o Mercosul (Mercado Comum do Sul), enquanto iniciativa de integração regional na América do Sul, tem contemplado questões migratórias desde sua criação, em 1991, ou se prioriza a mobilidade de capitais e de bens e serviços. O presente estudo tem caráter qualitativo e descritivo e utiliza-se fundamentalmente do método bibliográfico, sendo a revisão teórica referente à questão migratória na teoria econômica e os resultados pautados na análise de protocolos, acordos e tratados do Mercosul. Conforme os documentos analisados, nas primeiras fases desde a criação do bloco, os temas relacionados a pessoas estiveram majoritariamente vinculados à educação, apenas recentemente dando maior ênfase a questões migratórias. Trinta anos após sua criação, os países do Mercosul ainda não conseguiram realizar plenamente o que se propuseram de início, que era fazer do bloco um mercado comum. Apesar das recentes iniciativas para resolução de problemas dentro da temática migratória, os resultados apontam que o Mercosul ainda carece de maior integração e sincronia ante a política de migração de seus países, buscando medidas inovadoras e não apenas reativas aos acontecimentos.

Aim. To assess the development of adverse cardiovascular events in patients with non-obstructive coronary artery disease (CAD) and coronary microvascular dysfunction (CMD), identified by dynamic myocardial single-photon emission computed tomography (SPECT), during 12-month follow-up compared with patients without CMD.Material and methods. The study included 118 patients (70 men, mean age, 62,0 [58,0; 69,0] years) with preserved ejection fraction (62 [59; 64] %) and non-obstructive CAD. Serum levels of the N-terminal pro-brain natriuretic peptide were assessed at baseline by enzyme immunoassay. Coronary flow reserve (CFR) was assessed by dynamic SPECT. CFR ≤2 was a CMD marker.Results. Six patients discontinued participation in the study due to loss of contact with them, while the rest were divided into groups depending on CMD presence: group 1 included patients with CMD (CFR ≤2; n=42), and group 2 was the control group and included patients without CMD (CFR >2; n=70). Within 12-month follow-up, 25 patients reported adverse events. According to Kaplan-Meier analysis, the prevalence of adverse cardiovascular events was higher in patients with CMD (45,2%, n=19) than in patients without it (8,6%, n=6) (p<0,001). Multivariate regression analysis showed that the presence of CMD (odds ratio (OR), 2,42; 95% confidence interval (CI), 1,26-5,85; p<0,001) and diastolic dysfunction (OR, 3,27; 95% CI, 2,26-5,64; p<0,001) were independent predictors of poor outcomes. The combination of CMD with diastolic dysfunction more than 5 times increased the risk of adverse events (OR, 5,18; 95% CI, 3,61-11,84; p<0,001).Conclusion. We found that in patients with non-obstructive CAD, the presence of CMD, identified by dynamic myocardial SPECT, was associated with a higher risk of adverse cardiovascular events within 12-month follow-up period than in patients without CMD. At the same time, the combination of CMD with diastolic dysfunction more than 5 times increased the risk of adverse outcomes.

Published: April 2023

Aim. To compare the effect of insulin therapy and oral hypoglycemic agents (OHAs) on the risk of heart failure (HF) in patients with type 2 diabetes (T2D) using different databases.Material and methods. The systematic review and meta-analysis were carried out in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. The analysis included studies that compared the risk of HF in T2D patients, depending on the OHA therapy in the presence of a group of patients receiving insulin therapy. The inclusion criteria were a duration of treatment of at least two years with at least 1000 included patients. The analysis did not include studies that compared the types and regimens of insulin therapy without a control group (antidiabetic drugs), which included patients with acute complications of type 2 diabetes and unstable conditions associated with comorbidities, in which no clinical outcomes were reported. Search was conducted in August 2022 using several databases (PubMed, Cochrane Central Register of Controlled Trials (CENTRAL) at the Cochrane Library, Elibrary) using the following keywords: heart failure development, 2 type diabetes mellitus, insulin.Results. Of the 1085 publications found in the search, 5 retrospective observational cohort clinical trials, including a total of 179777 patients with a mean duration of treatment of 67,2 months, met all criteria and were included in the analysis. Statistical analysis of the relative risk (RR) of HF in T2D patients receiving insulin therapy revealed a RR increase in all studies with a total RR using fixed effects model of 2,598 (95% confidence interval (CI), 2,346-2,878; p<0,001), while using the random effects model — 2,382 (95% CI, 1,565-3,626; p<0,001). When checking the statistical heterogeneity of the studies, a high heterogeneity was revealed (I2=93,8%).Conclusion. Meta-analysis of 5 retrospective observational studies including 179777 patients with T2D with a mean duration of treatment of 67,2 months showed that insulin therapy (without insulin glargine and degludec) in comparison with OHAs (without sodium-glucose cotransporter-2 inhibitors and glucagon-like peptide type 1 receptor agonists) significantly increased the RR for HF using a fixed effects model by 2,6 times, while using the random effects model — by 2,4 times (p<0,001 for both).

Published: April 2023

As árvores exercem papel fundamental na qualidade ambiental e seus benefícios são indiscutíveis para a vida nas cidades. A expansão e crescimento urbanos sem fundamentação no planejamento arbóreo geram prejuízos na provisão desses serviços ambientais. O presente estudo teve como objetivo conhecer a composição florística e caracterizar a heterogeneidade e similaridade entre os indivíduos arbóreos de diferentes bairros do município de São Paulo. Os resultados indicaram alta similaridade de espécies entre bairros, conforme índice de Jaccard, e alta diversidade de espécies segundo índice de Shannon Weaver (H’) para os sete bairros avaliados na cidade de São Paulo, SP. Analisar a diversidade arbórea na cidade e planejar novos plantios atentando-se para a manutenção equilibrada de árvores da mesma espécie, gênero e família é primordial quando se almeja um planejamento arbóreo coerente e que considera a restauração dos ecossistemas degradados.

Published: April 2023

Severe pneumonia is a condition with a high risk of death and mandatory hospitalization in the intensive care unit. The incidence of severe pneumonia has increased dramatically during the pandemic of new coronavirus infection. Timely diagnosis and early initiation of adequate treatment of severe pneumonia are crucial for improving survival of critically ill patients.The aim of this review was to analyze published scientific research on molecular markers that allow to objectively assess the severity of pneumonia and to determine treatment tactics based on the predicted outcome upon admission to the hospital. A systematic search was conducted in the electronic databases PubMed, Medline, Web of Science for the period 2019 - 2022.Conclusion. The review focuses on the prognostic role of a number of markers of immune response, vascular transformation, as well as angiotensin II and angiotensin converting enzyme-2. Further prospective studies of potential predictors of severe pneumonia will enable using marker molecules in a comprehensive clinical and laboratory diagnosis for early prediction of the hospitalized patient’s condition and expected outcome.

Published: April 2023

Birt - Hogg - Dubd (BHD) disorder is a rare inherited autosomal dominant disorder caused by germline mutations in the tumor suppressor gene FLCN, which encodes the protein folliculin. BHD disorder is characterized by benign skin hamartomas, kidney cancer, pulmonary cysts, and spontaneous pneumothorax. Currently, more than 600 cases of this disease have been described worldwide. Diagnosis of BHD disorder is based on clinical manifestations, family history, and genetic testing. We describe two patients (43 and 51 years old) who presented with a history of longstanding dyspnea and spontaneous pneumothorax. Based on the radiological characteristics and skin lesions, the patients were referred for genetic testing to confirm the diagnosis of BHD disorder.Aim. To study the current management of adult patients with BCD disorder. Timely diagnosis of BHD disorder has important preventive value because patients with this disease are at much higher risk for kidney cancer.Conclusion. The presented clinical cases demonstrate typical manifestations of BCD disorder with predominant involvement of the lungs and skin. The final diagnosis is confirmed by genetic testing of the coding sequence of the FLCN gene by direct automated sequencing. To date, there are no specific therapies for BCD disorder and treatment of the respiratory manifestations is limited to prevention and treatment of pneumothorax.

Published: April 2023

Sex determination is an important aspect in identification of individuals especially in cases of identifying victims of mass disasters, organised crimes etc. Odontometry is the measurement and study of tooth size. Cranial anthropometry is the measurement of skull dimensions and is considered to be a versatile technique in the investigation of the craniofacial skeleton because of its validity and practicality.To assess tooth crown area of the deciduous molar teeth, to assess head size, to evaluate the extent of sexual dimorphism using head and dental dimension: This study was done in 150 boys and 150 girls. Maxillary and mandibular arch impressions were made, casts were made with dental stone. A vernier calliper was used for obtaining the measurements. Mesiodistal width and buccolingual width of all the molars were measured in millimetres, tooth crown area (TCA) was calculated. Head dimensions were measured using Martin spreading calliper, Cephalic Index (CI) was calculated. Statistical analysis was done using unpaired “t” test, and logistic regression analysis was performed.: The highest tooth crown area was shown by mandibular left second deciduous molar for both boys and girls (p&#60;0.05). Boys showed higher cephalic index compared to girls (p&#60;0.05). The highest percent dimorphism was obtained for maxillary left first deciduous molar.Tooth crown area and head size can serve as a valuable aid for sex determination in pediatric population.

: To compare the efficacy of active oxygen - containing mouthwash (BlueM) with chlorhexidine mouthwash (Hexidine) and its effect on plaque, calculus, and gingival inflammation.A Double blind parallel study was done on 20 systemically healthy patients with the presence of generalized chronic gingivitis in the age group of 20-45 years. Each subject will rinse their mouth with the mouthrinse assigned to them, or twice daily for one minute in the morning and before going to bed. They will be instructed to swish it properly around the mouth and avoid its ingestion. Descriptive statistics was performed by calculating mean and standard deviation for the continuous variables. Intergroup and intragroup comparisonbetween chlorhexidine and Blue M at baseline (To) and at the end of 3 weeks (T1) showing no statistical differences between the two groups.Blue M can be used as a safe alternative to chlorhexidine in reducing the microbial load. But when compared to each other there wasn't a significant change between them. Chlorhexidine has the edge in being very cheaper compared to Blue M. Further studies are required with conclusive evidence to be able to determine whether oxygen enriched mouthwashes can replace chlorhexidine in the future.
