INTRODUCTION:

Individuals with familial adenomatous polyposis (FAP) have an almost 20% lifetime risk of duodenal adenocarcinoma, currently the leading cause of death in FAP. The Spigelman staging system provides guidance on the surveillance intervals and timing of prophylactic surgery. Still, its accuracy in predicting duodenal and papillary cancer development has not been systematically evaluated. We investigated the sensitivity and cancer risk of the Spigelman stages.

METHODS:

We performed a systematic review on PubMed, MEDLINE, EMBASE, and Cochrane and used a random-effects model to pool effect sizes.

RESULTS:

After removing duplicate entries, we screened 1,170 records and included 27 studies for quantitative analysis. Once duodenal polyposis reaches Spigelman stage IV, the risk of duodenal and papillary cancers increased to 25% (95% confidence interval [CI] 12%–45%). However, the sensitivity of Spigelman stage IV for these cancers was low (51%, 95% CI 42%–60%), especially for papillary adenocarcinoma (39%, 95% CI 16%–68%). We investigated the reasons behind these low values and observed that duodenal cancer risk factors included polyps >10 mm, polyp count >20, and polyps with high-grade dysplasia. Risk factors associated with papillary cancer included a papilla with high-grade dysplasia or >10 mm. The evidence on other risk factors was inconclusive.

DISCUSSION:

The current Spigelman staging system had a low sensitivity for duodenal and papillary adenocarcinomas. Two Spigelman variables (duodenal villous histology and polyp count) and the lack of papilla-specific variables likely contributed to the low sensitivity values for duodenal and papillary cancers, respectively. While clinicians may be familiar with its current form, there is an urgent need to update it.
Periodização do desenvolvimento psicológico das crianças, o brincar e a formação docente: possíveis diálogos
Authors: Aparecida Dias Lacerda Valéria , Silva Fernanda Duarte Araújo
Published: January 2024

O presente artigo tem como objetivo apresentar estudos sobre as regularidades e não regularidades do desenvolvimento psíquico da criança, além da relação com o brincar como uma das atividades que atravessam o desenvolvimento psicológico. Para alcançar tal objetivo, realizamos um levantamento de estudos, artigos e livros que abordam a questão da periodização das idades proposta por Vigotski e colaboradores da Teoria Histórico-cultural, sobretudo Leontiev e Elkonin. A criança se educa e se humaniza por meio da apropriação da cultura, assim o brincar é um apropriar-se e estar no mundo. O brincar se constitui como uma das atividades potencializadoras do desenvolvimento infantil e, como tal, deve ser tomado como um dos principais eixos à constituição de relações, reflexões e prática social junto às crianças. Em linhas gerais, podemos afirmar que, pensar as questões relacionadas ao brincar nos mobilizam a repensar a formação docente, pois argumentamos que as professoras devem considerar o brincar e a periodização do desenvolvimento psicológico das crianças na organização do trabalho pedagógico, com o escopo de superar visões e atitudes simplistas. Espera-se que a formação docente, inicial e continuada, ofereça subsídios teóricos, didáticos e metodológicos para possibilitar, às profissionais da educação, compreender a importância do adulto na apresentação do mundo à criança e na organização e no planejamento de situações que as propiciem compreendê-lo e experienciá-lo em diversas formas e possibilidades.

Devorando a cena
Authors: Cabral Fonseca Michelle Nascimento , Conceição Raylson Silva
Published: January 2024

Este estudo examina as transformações estéticas e metodológicas nos grupos de teatro locais que criam peças teatrais com base no folclore maranhense, bem como em questões étnico-raciais e de gênero. O quadro teórico adotado inclui conceitos como a “antropofagia” de Oswald de Andrade, o “pensamento abissal” e o “epistemicídio” de Boaventura Santos, a “violência epistêmica” e a “injustiça epistêmica” de Elizabeth Spelman e Miranda Fricker, respectivamente, além do “deslocamento epistêmico” de Lîla Bisaux. A aplicação do conceito de antropofagia na análise da cena teatral contemporânea de São Luís do Maranhão ressalta a relevância da justiça epistêmica ao reconhecer a diversidade de saberes e práticas culturais, evitando assim a exclusão de vozes e perspectivas marginalizadas.
Outras histórias da arte na América Latina e a dissidência ao sistema de sexo/gênero em Gloria Cortés Aliaga e Miguel A. López a partir da perspectiva feminista
Authors: Ayres Alves Ricardo Henrique
Published: January 2024

O presente texto procura aproximar duas iniciativas latino-americanas no campo das artes visuais, a exposição (en)clave Masculino, curada pela chilena Gloria Cortés Aliaga e o livro Ficciones Dissidentes en la Tierra de la Misoginia, do peruano Miguel A. López, entendendo-as como iniciativas que, a partir de uma perspectiva feminista, exercem críticas aos discursos hegemônicos do sistema de sexo/gênero. A partir de uma discussão que pensa a modernidade e a arte em uma perspectiva decolonial, são analisados os discursos dos autores bem como suas iniciativas, sendo possível identificar a partir deles tanto a emergência da perspectiva feminista como uma possibilidade de pensar outras histórias da arte, assim como a relação entre essas novas escritas e a prática curatorial.

Pyrolysis of Polyethylene from Plastic Waste using Activated Ende Natural Zeolite as a Catalyst
Authors: Bani Gregorio Antonny , Bani Mario Donald
Published: January 2024

Plastic waste has many complex chemical components. In developing countries, direct incineration is often used to reduce plastic waste, releasing pollutants into the atmosphere. A more environmentally sound alternative is pyrolysis. It can turn plastic waste into an alternative fuel. A catalyst, such as natural zeolite, can reduce the energy used in pyrolysis. However, mineral contaminants must be removed first to get optimum activity. This research was focused on using Ende natural zeolite as a catalyst, determining the properties of the mineral in its activated form. It also investigated the interaction between H-zeolite composition and the operating temperature towards pyrolysis oil yield. The experimental results showed that Ende natural zeolite contained a mixture of mordenite, clinoptilolite, and quartz. After activation and modification, there was an increase in the surface area from 53.17–104.67 m2/g. The average pore radius ranged from 19.96–34.21 Å. There was an increase in the pore volume from 22.01–72.34 cc/g. The total acidity changed from 1.456–5.342 NH3/g. The optimum catalyst concentration was 10% in the pyrolysis of 1000 grams of plastic waste catalyzed by 100 grams of H-zeolite. The oil yield decreased at 15% concentration. The 10% concentration worked best at 400 ℃.

A serious problem of the Magadan region – the northern region of resource specialization with a leading gold mining industry – during the development of market relations is the ongoing process of devastation of the territory. In order to identify spatial transformations at the level of municipalities in the region, a retrospective analysis of changes in 1990–2020 in key areas of the economy and social sphere was carried out. The specific features of the transformations in the municipal context are: large-scale outflow of population from the areas of the main type of activity; the formation of an urban agglomeration (82% of the population of the region); changes in the spatial localization of economic activity and budgetary self-sufficiency due to the beginning of the development of ore deposits of precious metals by the shift method; deterioration of the standard of living of the population
Intervention for the conservation and restauration of a Japanese domestic altar
Authors: Macedo Marrocano João Henrique
Published: January 2024

The conservation and restoration intervention carried out in a Japanese domestic altar, dating from the 19th century, belonging to the Fundação Oriente - Museu do Oriente, in Lisbon, had as its main objectives the restoration of its functional utility, stabilize and repair physical and structural problems, and the restitution of its colour unit. In response to these problems, there was a need to address the issue that the preservation of lacquered oriental objects has been showing, not only in relation to oriental criteria but, above all, in relation to conservative issues adopted in the West. In this sense, the weighting of the intervention criteria passed by treatments oriented according to the minimum intervention and the safeguarding of the removal and compatibility of the materials and techniques used, favouring long-known materials and that had the least impact of the intervention on the good, and in its natural aging process.
Historical-scientific heritage and the university: the two pillars of the History of Pharmacy collection in the Faculty of Pharmacy of the University of Seville
Authors: Ramos Carrillo Antonio , Moreno Toral Esteban , Ruiz Altaba Rocío
Published: January 2024

The permanent exhibition space created in the Faculty of Pharmacy in the University of Seville (Spain) operates as a teaching and research centre. All pieces in the collection are inventoried and displayed in a permanent, coherent and orderly exhibition that serves as an educational tool for all walks of life. This article explains how the pieces are managed, as well as the advantages and disadvantages of creating and disseminating a historical-scientific collection in a field as specific as a university. We also explore the contrast between the concepts of “conservation” and “new technologies” that are so often unthinkingly bundled together in historical collections today.
The colours of deception: marble imitations in Alentejo stucco altarpieces
Authors: Monteiro Patrícia
Published: January 2024

This paper will discuss how modern interventions changed the image of stucco altarpieces and their original polychromies. These works of art form a consistent group whose presence can still be seen in the Alentejo (Portugal), built between the 16th and 20th centuries. Although its popularity in this region over the centuries cannot be overstated, this artistic heritage has been misunderstood in terms of constituent materials, artisanal construction techniques, and polychrome coatings. All of the mimetic potentials of these altarpieces were laid out in their colourful finishing which successfully imitated other materials, particularly marble. This visual image was irreversibly altered because of intensive whitewashing or modern repainting with synthetic materials. We will examine how local populations have reacted to this historical heritage through various examples, taking into account psychological, cultural, and even economic factors.
Effect of Population Density and Urban Intensity on Building Typology in South Krembangan Area
Authors: Puspita Cindy , Dharmatanna Stephanus Wirawan
Published: January 2024

Surabaya is the second largest city in Indonesia and is part of East Java. Surabaya has a strategic location and was utilized by the Dutch Colonial Government as one of the main ports. The Kalimas River served as the trading artery of Surabaya. Surabaya was broadly divided into three dominant areas: the European district, the Chinatown district, and the Arab district, all of which are delineated by the Kalimas River. Krembangan Selatan Village is of particular interest for research due to the presence of many colonial-style buildings and the shift from a historical trading area to a residential area.  To understand the influence of population density and urban intensity on building typology, a qualitative descriptive analysis was conducted by observing building typology and the year of construction which helped in determining how population density and intensity affect building typology in the Krembangan Selatan area. Urban Intensity was assessed by calculating the building volume divided by 300. The highest intensity group consists of residential areas with buildings in a typical style of the 1960s. Density calculations were made by comparing the area to Semarang, as both areas were influenced by the Dutch colonial Government.  This occurred because Semarang's Old Town area still maintains its urban tissue as a historical area dominated by public buildings, in contrast to Krembangan Selatan, which is dominated by service providers, educational facilities, and residential buildings.

„Diamonds are a girl’s best friend?“ Diamanten, DeBeers und die Vermarktung von Brillantschmuck in den USA, 1939–1960
Authors: Rudolph Mona
Published: January 2024

Heutzutage stellen Diamanten ein äußerst gefragtes Gut dar, allerdings entwickelten sich die Edelsteine erst im Laufe der Zeit zu dieser absatzstarken Ware. Von den 1890er Jahren bis zum Zweiten Weltkrieg unterlag die Nachfrage nach den Steinen in den USA als weltweit größter Absatzmarkt erheblichen Schwankungen. Um die schwache US-amerikanische Nachfrage anzukurbeln, lancierte der Diamantenproduzent DeBeers zusammen mit der Werbefirma N. W. Ayer ab 1938 großangelegte und aufwändig gestaltete Werbekampagnen. Am Beispiel dieser Werbeanzeigen untersucht und rekonstruiert der Aufsatz die Vermarktung von Brillanten in den USA vom Zweiten Weltkrieg bis in die 1960er Jahre. An den Schnittstellen von Wirtschafts- und Kulturgeschichte angesiedelt, spürt die Untersuchung unter Berücksichtigung geschlechtergeschichtlicher Perspektivierungen den ökonomischen Interessen des DeBeers-Konzerns nach und fragt dabei immer wieder, wie sich die Wahrnehmung von Brillantschmuck im Laufe der Zeit wandelte. In den Werbeanzeigen richtete sich DeBeers zunächst vorrangig an unverheiratete Paare als Konsumenten, berücksichtigte bis in die 1960er Jahre jedoch eine zunehmend größer werdende Klientel. Dennoch achtete das Unternehmen sorgsam darauf, die Illusion des als rar und elitär geltenden Luxusguts zu bewahren und den Markt weiterhin zu regulieren. Letzteres fiel dem Konzern mit der Zeit immer schwerer, da permanent neue Produzenten auf den europäischen Diamantenmarkt drängten. Unter Zuhilfenahme wirtschaftswissenschaftlicher Theoreme rückt der Aufsatz in diesem Zusammenhang auch in den Blick, wie Diamanten allmählich zu einem Massenprodukt wurden, ohne als solches wahrgenommen zu werden.
Thermodynamic modelling application for prediction of diffusion formation of supersaturation solution
Authors: Rodin Alexey , Mween Bright , Khvan Alexandra , Lepkova Tatiana , Goreslavetz Natali
Published: January 2024

In this paper the effect of diffusion formation of supersaturated solid solution in the Al–Ge system is discussed. It was shown that at relatively low temperatures of diffusion annealing, Ge concentration in Al-based solid solution became higher than the solubility limit at given temperatures. The maximal concentration of Ge was determined by extrapolation of the diffusion profile on the Ge/Al interface. Analysis of diffusivity of Al in Ge allowed to suggest that slow diffusion in Ge restricts the formation of Ge-based solid solution. Qualitative approach confirmed this suggestion.
Modified linear sampling method for inverse scattering by a partially coated dielectric
Authors: Xiang Jianli , Yan Guozheng
Published: January 2024

Consider time-harmonic electromagnetic wave scattering by an infinitely long, cylindrical, orthotropic dielectric partially coated with a very thin layer of a highly conductive material, which can be modeled by a transmission problem with mixed boundary conditions. Having established the well-posedness of the direct and interior transmission problem by the variational method under certain conditions, we make use of the classical linear sampling method to reconstruct the shape of the obstacle. Then, based on a modification of the general data-to-pattern operator G, we propose a novel and simple method to justify the modified linear sampling method.
Subclinical cardiac impairments in fetuses conceived through assisted reproductive technology by speckle tracking echocardiography
Authors: Gao Yipeng , Deng Youbin , Huang Peina , Cheng Xueqing , Lu Ruirui , Fan Yating , Liu Hongyun
Published: January 2024

Objectives

To evaluate the changes of cardiac morphology and function in fetuses conceived through assisted reproductive technologies (ART) by speckle tracking echocardiography.

Methods

A retrospective study was conducted in 101 spontaneously conceived (SC) fetuses and 99 ART-conceived ones. Fetal echocardiography was performed, fetal cardiac morphology and function were analyzed using two-dimensional speckle tracking software, including global sphericity index (GSI), global longitudinal strain (GLS), fractional area change (FAC) of the left and right ventricles, as well as segmental sphericity index (SI), end-diastolic diameter (ED), and fractional shortening (FS) in 24 segments.

Results

Compared to the SC fetuses, the ART-conceived fetuses exhibited decreased GSI (median [interquartile range], 1.22 [1.16–1.27] vs. 1.18 [1.11–1.24], p=0.007), decreased right ventricular GLS (24.9 [21.5–27.6] vs. 23.2 [20.4–26.8], p=0.026), and decreased right ventricular FAC (mean ± standard deviation, 39.7 ± 6.4 vs. 37.2 ± 7.1, p=0.003). Analysis of the 24 segments showed that ART-conceived fetuses had reduced SI in the apical segments of right ventricle and increased ED in several segments of the right ventricle.

Conclusions

Fetuses conceived through ART had a more spherical shape of the global heart and predominantly right-sided cardiac remodeling and systolic function impairment.
Power, Capacity, Disposition and Categorical Properties: A Roughly Aristotelian Proposal
Authors: Brook Angus
Published: January 2024

This paper proposes a roughly Aristotelian account of powers ontology. In doing so, the paper uses the distinction found in Aristotle between four analogous senses of potency to explain causation and the existence-essence distinction in substances. On this basis, the paper offers some justification in support of the claims that powers and dispositions are the truth-makers of categorical properties and that categorical properties are ontologically dependent upon powers and dispositions.
Easy Ontology and Undecidable Sentences
Authors: Jafari Javid
Published: January 2024

According to Thomasson’s Easy Ontology, all existential questions have straightforward answers and are solvable by conceptual and empirical work. So there is no need for traditional metaphysics to solve them. First, I give some counterexamples to this thesis from incomplete and undecidable theories. Then I discuss some possible responses, I consider a wider sense of conceptual analysis and argue that even in this sense Easy ontology is not able to resolve the problem and must sacrifice either easiness or answerability. Finally, I will argue that although traditional metaphysics does not make the undecidable sentences answerable, it can still make sense of them and helps us to understand why there are unanswerable questions at all.
Effects of repeated replanting on yield, dry matter, starch, and protein content in different potato (Solanum tuberosum L.) genotypes
Authors: Mikó Péter Pál , Percze Atilla , Kovács Ágnes , Kende Zoltán
Published: January 2024

This investigation scrutinized the yield, starch, and protein content of five distinct potato genotypes (Desiree, Borostyán, Piroska, Rubinka, and Rózsa) over 5 years of repetitive replanting. The experiment aimed to compare different potato genotypes and examine the yield reduction resulting from possible genetic deterioration over the years. The research took place in Zirc, Hungary’s temperate deciduous forest zone, at 450 m elevation from 2017 to 2021, on a 100 m2 plot. Potato dry matter was measured according to MSZ 6369-4:1987, and starch content followed MSZ 6830-18:1988 standards. Tubers’ total nitrogen was gauged using the Kjeldahl method, while crude protein analysis employed the Dumas method. Pure protein evaluation adhered to the trichloroacetic acid precipitation technique, all consistent with WBSE-131:2018. Observed variations in starch content revealed Borostyán as the genotype with the highest mean starch content (75.41%) and Desiree with the least (74.98%). Protein content also varied among the genotypes; Borostyán exhibited the highest average level (10.99%), while Desiree had the least (5.52%). The remaining genotypes, Piroska, Rubinka, and Rózsa, exhibited comparable mean protein levels between 8.15 and 8.82%. Findings also noted a positive correlation between yield and starch and protein content. However, certain genotypes demonstrated a negative correlation, highlighting the impact of genetic factors and management practices such as nitrogenous fertilization and crop rotation on these associations. Additionally, the findings suggest that not only the standard Desiree variety but also the Borostyán variety can be reliably recommended for use in potato research and breeding initiatives. Conclusively, this study provides insights valuable for potato breeding and selection programs and the potential development of high-protein potato products. Further investigation is recommended to elucidate the mechanisms and genetic determinants that impact these observed relationships.

Published: January 2024

Composites are becoming materials of the future. Composite applications have become popular in the air as airframes in the aerospace industry to the deepest seas in the form of underwater pipes. A sandwich structure is a composite with cores with low-density material pinned by a stiff facing. In this article, the sandwich material used is a Nomex-Aramid honeycomb as the core and carbon fiber composite as the facing sandwich structure. The main goal of this study is to obtain the characteristics of the sandwich structure, Nomex-Aramid carbon fiber, and study the effect of core variation on the overall strength of the sandwich structure. Numerical simulation testing was carried out to determine the characteristics of the sandwich structure. The loadings carried out were mainly three-point bending, tensile, compression, and torsional tests. In addition, this study also compared the geometry of cores and several materials to study the effect of core properties on the overall strength of the materials. The authors used the finite element method with ABAQUS. A mesh convergence study was also conducted in this article. The results of the numerical simulation showed that the structure sandwich had a major drawback in the local strength caused by the size of the cells used. In addition, the geometric shape and type of the core material also affected the strength of the sandwich structure.

Purpose: to investigate the occurrence of dystonic type response to physical activity in the form of submaximal PWC170 test in soccer players. Material & Methods: 741 soccer players divided into 3 groups according to their sports qualification were examined. The data of 68 high-class soccer players with "infinite tone" and 69 high-class soccer players without "infinite tone" were compared, 251 advanced soccer players with "infinite tone" with 179 advanced soccer players without "infinite tone", and 69 intermediate soccer players with "infinite tone" with 105 similarly qualified soccer players without "infinite tone". Blood pressure was measured by the Korotkoff method using an aneroid sphygmomanometer (Romed, Netherlands) on the right arm. Three measurements were taken 5 minutes apart, and the lowest reading was used. Physical working capacity was assessed on a bicycle ergometer (Corival, Netherlands). Results: it was found that physical working capacity didn't differ significantly between athletes with and without "infinite tone", and in the group of advanced athletes was significantly higher in players with "infinite tone". The same number of soccer players with signs of metabolic cardiomyopathy was found with and without “infinite tone” (p=0.916). Conclusions: dystonic type of reaction of cardiovascular system to physical load in the form of submaximal PWC170 test with "infinite tone" is found in 52,4% of examined soccer players, more often in advanced athletes aged 19 (18; 22) years – 64,7%, in comparison with intermediate players aged 16 (15; 17) years – 17,8%, p<0,001, which doesn’t confirm the opinion about occurrence of "infinite tone" in adolescents during puberty. The absence of significant differences in most of the studied indicators, in particular, the relative value of physical working capacity and blood pressure at 5 minutes of recovery period, indicates the unrelated appearance of "infinite tone" in soccer players of different sports qualification. The opinion of scientists that the dystonic type of reaction to physical load with "infinite tone" is physiological and the reaction is atypical is confirmed with the recommendation to make corrections in the section "Functional tests" of the national textbook "Physical Rehabilitation. Sports Medicine".

Purpose: psychological stress caused due to the current COVID 19 pandemic lock down may have an adverse impact on the quality of life (QoL) in office shift workers. The purpose of the present study was to investigate the effect of OM chanting on the levels of perceived psychological stress, quality of life and sleep among office workers who are confined at home and work during the global COVID-19 pandemic. Material & Methods: an online OM chanting session was conducted for 20 workers who stayed at home and worked during the pandemic lockdown. Prior to and at the end of the training all the participants finished a battery of self-reported online inventories, including the Depression, Anxiety and Stress Scale with 21 items (DASS-21) and quality of life (WHOQOL-BREF). Results: after ten days of OM chanting, all the participants stated a significant enhancement in all domains of quality of life and a reduction of psychological distress (P<0.05). Conclusions: OM chanting is feasible, safe and has a positive effect on psychological quality of life of participants. Still further studies have to be done to warrant the findings with suitable study design.

Purpose: to determine changes in the parameters of cardiorespiratory relationships during the maneuver with a change in breathing rate after a 4-month cycle of training aimed at the development of strength endurance. Material & Methods: the results of the spiroarteriocardiorhythmographic study of 22 healthy men aged 20.7±2.3 years, who for 4 months 2 times a week for 90 minutes, were analyzed (a total of 30 classes were held) engaged in training for the development of strength endurance. The indicators of heart rate (min–1), respiratory rate (min–1), cardiac output (dm3×min–1), minute lung ventilation (L×min–1) and their derivatives – the Hildebrandt index (HR/RR) and volume synchronization index (CO/V), which were obtained during spontaneous respiration and controlled breathing at 0.1 Hz and 0.25 Hz. Results: it was shown that strength endurance training led to a probable decrease in heart rate from 71.4 (63.9; 77.5) to 64.3 (60.8; 68.3), p=0.002, respiratory rate from 14.1 (12, 7; 16.8) to 13.8 (10.7; 15.3), p= 0.020 and minute lung ventilation from 8.19 (6.24; 8.86) to 6.40 (3.73; 7.74) ), p=0.004 during spontaneous breathing, as well as a significant increase in the volumetric synchronization index. (dm3×L–1) during spontaneous respiration from 0.597 (0.490; 0.832) to 0.725 (0.564; 1.148), p=0.008, during controlled respiration at 0.1 Hz from 0.327 (0.382; 0.529) to 0.532 (0.441; 0.723), p=0.012 and during controlled respiration at 0.25 Hz from 0,245 (0,339; 0,455) to 0,481 (0,373; 0,616), р=0,003 against the background of a decrease in the Hildebrandt index during controlled respiration 0,1 Hz from 11.14 (10.43; 12.49) to 10.18 (9.54; 11.00), p=0.001, as well as with controlled respiration at 0.25 Hz from 5.33 (4.68; 5.85) to 4.46 (4.13; 4, 78), p=0.000. Conclusions: endurance training for 4 months led to an economization of the cardiovascular and respiratory systems function and a decrease in the response to sympathoadrenal activation and hyperventilation.

Functional diversity along disturbance and environmental gradients in Ethiopian moist Afromontane forest
Authors: Jeldu F. A. , Tolera M. , Woldeamanuel T.
Published: January 2024

Considering multiple measures to fully capture functional diversity is important. However, the effects of disturbance gradients on diversity have been controversial, as species diversity alone may not fully capture these effects. This study aimed to evaluate trait-based diversity across disturbance gradients in the moist Afromontane forest of Ethiopia, Yayu Coffee Forest Biosphere Reserve (YCFBR). Vegetation data and relevant traits related to plant-life strategies, competition, and responses to disturbances were collected. A multiple regression model was used to test the response of functional diversity to disturbances and environmental gradients. The results revealed functional diversity in plant communities, including dendrogram-based functional diversity for plot-based (FDp), functional richness (FRic), functional evenness (FEve), functional divergence (FDiv), functional dispersions (FDis), and community-weighted mean of maximum tree height (CWM.Hmax), showed decreasing patterns with increasing disturbance intensity in the YCFBR. Additionally, the findings highlighted that FDis and Hmax are the most vulnerable functional traits to anthropogenic factors and are less tolerant in disturbed ecosystem environments. Therefore, reducing disturbances is crucial to maintaining higher levels of these functional diversities. For example, the results showed that the CWM.Hmax declined from 27.25 m to 15 m, indicating a shift towards shorter plant species. In contrast, the community-weighted mean of woody density (CWM.WD), the community-weighted mean of specific leaf area (CWM.SLA), and the community-weighted mean of seed mass (CWM.SM) increased significantly with an increase in disturbance intensity. For instance, CWM.SM and CWM.SLA changed from 5 to 14.25 (g) and 90 to 130 (cm2/g), respectively. These indices may serve as indicators of ecosystem resilience at disturbed forest ecosystem sites. Furthermore, the regression results indicated that FDp, FRic, FEve, FDiv, FDis, CWM.WD, and CWM.Hmax showed increasing patterns with increasing species richness, which suggests that protecting and promoting species diversity can contribute to maintaining high levels of functional diversity. The mixed effects model revealed that anthropogenic disturbance and elevational gradients had significant effects on functional diversity in the YCFBR. Therefore, when managing and conserving biodiversity in heterogeneous environments, both anthropogenic factors and environmental variables need to be considered. Species with low SLA and SM are recommended for the restoration of disturbed ecosystems. Overall, this study demonstrates that trait-based functional diversity is useful for predicting the adaptation potentials of species in heterogeneous environments and disturbance gradients.

Due to the limited knowledge on bryophytes in Algeria, this study aimed to update the Algerian bryophyte flora. Megriss Mountain (also called Jbel or Djebel Megriss), which is a part of the High Plains of Setif, was chosen as a study area for its interesting biological and landscape diversity. The inventory was carried out in different habitats (rocks, trees, soils and streams). Samples were collected from minimum survey areas of 100 cm2 (from soil and rocks), but the sample area was sometimes increased depending on the availability of species; the trees were mostly sampled between heights of 1 and 2 meters. As a result, a preliminary list of 55 moss species were identified, including 44 acrocarpous and 11 pleurocarpous, belonging to 13 families and 29 genera. The most species-rich families were Pottiaceae, Orthotrichaceae, Brachytheciaceae, and Bryaceae, while the most diverse genera were Lewinskya and Syntrichia. Epilithic mosses were dominant, followed by terricolous mosses and finally epiphytic mosses. The most frequent species in the study area were Orthotrichum diaphanum, Lewinskya acuminate, Didymodon insulanus, Grimmia pulvinata, and Tortella squarrosa. The study also highlights the presence of a new species that had never been recorded in Algeria -Orthotrichum scanicum. A comprehensive description, microphotographs of the species are provided and its ecology is also discussed. This discovery will contribute to the enrichment of the Algerian bryophyte flora in general and of the Orthotrichaceae in particular,within the genus Orthotrichum, which now has a total of 11 species recorded in the country.

Videospiele gelten in Deutschland als Kulturgut und sollen als solches geschützt werden. Dazu gehört auch die langfristige Erhaltung des digitalen Mediums. In diesem Artikel geht es um die urheberrechtlichen Herausforderungen, die dabei in Deutschland auftreten. Auf die Beleuchtung der einschlägigen Regelungen folgt eine Untersuchung, inwieweit Kulturerbe-Einrichtungen zur Erhaltung und Archivierung von Videospielen berechtigt sind. Es zeigt sich, dass der Kopierschutz ein großes Hindernis darstellt, da die Umgehung nur in bestimmten Fällen erlaubt ist. Des Weiteren wird deutlich, dass der Besitz der zu erhaltenden Werke im Bestand der Kulturerbe-Einrichtungen ihre Arbeit erleichtern kann. In den Besitz von nicht verfügbaren Videospielen zu gelangen, gestaltet sich allerdings weiterhin als Herausforderung.
Bei dem vorliegenden Artikel handelt es sich um einen leicht überarbeiteten Ausschnitt aus einer Bachelorarbeit, in welcher der Frage nachgegangen wird, wie Videospiele erhalten werden können. Neben der rechtlichen Lage werden dort außerdem technische Aspekte bei der Erhaltung von Games sowie Projekte mit dem Ziel der Bewahrung dieses Kulturguts untersucht.
