Severe presentations of malaria emerge asPlasmodium (P.) spp.parasites invade and lyse red blood cells (RBC), producing extracellular hemoglobin (HB), from which labile heme is released. Here, we tested whether scavenging of extracellular HB and/or labile heme, by haptoglobin (HP) and/or hemopexin (HPX), respectively, counter the pathogenesis of severe presentations of malaria. We found that circulating labile heme is an independent risk factor for cerebral and non-cerebral presentations of severeP. falciparummalaria in children. Labile heme was negatively correlated with circulating HP and HPX, which were, however, not risk factors for severeP. falciparummalaria. GeneticHpand/orHpxdeletion in mice led to labile heme accumulation in plasma and kidneys, uponPlasmodium infection. This was associated with higher incidence of mortality and acute kidney injury (AKI) in ageing but not adultPlasmodium-infected mice, and was corroborated by an inverse correlation between heme and HPX with serological markers of AKI inP. falciparummalaria. In conclusion, HP and HPX act in an age-dependent manner to prevent the pathogenesis of severe presentation of malaria in mice and presumably in humans.

Published: February 2024

Engineering optimization problems often involve nonlinear objective functions, which can capture complex relationships and dependencies between variables. This study focuses on a unique nonlinear mathematics programming problem characterized by a subset of variables that can only take discrete values and are linearly separable from the continuous variables. The combination of integer variables and non-linearities makes this problem much more complex than traditional nonlinear programming problems with only continuous variables. Furthermore, the presence of integer variables can result in a combinatorial explosion of potential solutions, significantly enlarging the search space and making it challenging to explore effectively. This issue becomes especially challenging for larger problems, leading to long computation times or even infeasibility. To address these challenges, we propose a method that employs the "active constraint" approach in conjunction with the release of nonbasic variables from their boundaries. This technique compels suitable non-integer fundamental variables to migrate to their neighboring integer positions. Additionally, we have researched selection criteria for choosing a nonbasic variable to use in the integerizing technique. Through implementation and testing on various problems, these techniques have proven to be successful.

Authors: Aya Baquero Dora Hilda , Acevedo Osorio Alvaro
Published: February 2024

Las políticas ambientales y de conservación de los ecosistemas naturales en Colombia, han pretendido excluir de estas áreas a las poblaciones humanas y sus actividades económicas. En áreas protegidas en Colombia (AP) habitan comunidades campesinas, afrodescendientes e indígenas que luchan por permanecer en sus territorios donde han construido su vida y su cultura. En este contexto de conflictos sociales relacionados a las áreas naturales protegidas, la “Declaración de las Naciones Unidas sobre los Derechos de los Campesinos y de Otras Personas que Trabajan en las Zonas Rurales” representa una oportunidad para la gestión de las AP, orientar insumos en la resolución de conflictos desde una perspectiva intercultural. La investigación recoge los antecedentes que dieron origen a la Declaración, los actores y escenarios de construcción de ésta. Plantea los elementos problema derivados de la gestión de las AP, las condiciones de vulnerabilidad y exclusión del campesinado y las debilidades en los instrumentos internacionales para defender sus derechos. Hace una justificación del proyecto a la luz de la construcción de paz, en el contexto de la implementación del Acuerdo de la Habana.  Es una investigación de tipo cualitativo, desde un enfoque histórico hermenéutico, para el análisis crítico de la Declaración y un Estudio de Caso del Área Protegida Parque Nacional Natural PNN el Cocuy, en el cual estaba descrito un conflicto ambiental que involucra una comunidad campesina. Los resultados de la investigación permiten evidenciar los ámbitos de aplicación de la Declaración como instrumento jurídico internacional de triple función: como generador de nuevas aproximaciones jurídicas frente a los derechos del campesinado en Colombia, para concretar /culminar procesos de política pública, especialmente en AP y, puede ser declarativa del derecho consuetudinario ligado al campesinado a partir del reconocimiento de éste como un sujeto histórico que se constituye a partir de múltiples dimensiones. Frente a la gestión de las AP, se evidencia su relación con un enfoque ecosistémico y el aporte para la gobernanza desde una perspectiva intercultural, básicos para la construcción de mecanismos de incidencia y desarrollo de capacidades en torno a la resolución de conflictos en AP y la defensa de los derechos del campesinado.

Authors: Oliveira Jéssica Rodrigues de , Silva Josie Agatha Parrilha da
Published: February 2024

A formação inicial de professores é um processo que exige muitas discussões acerca dos desafios da educação e da sociedade. A proposta interdisciplinar do ensino e dos saberes provenientes da prática docente pode ser uma importante ferramenta para a construção e unificação dos saberes de diversas áreas do conhecimento. Utilizando como aporte teórico a epistemologia de Paul Karl Feyerabend, este artigo tem por objetivo relacionar o pluralismo metodológico ao ensino, em especial, o ensino de Matemática em convergência com a Arte. Para isso, são apresentados os principais aspectos do pensamento de Feyerabend e suas relações com a transdisciplinaridade. São abordados, também, os saberes docentes de Maurice Tardif (2010) e as possíveis conexões da interdisciplinaridade com os saberes da prática docente. Por fim, destaca-se que o ensino — ancorado nas ideias do pluralismo metodológico e na transdisciplinaridade — contribui para o desenvolvimento integral do aluno e para a melhoria do ensino e aprendizagem da Matemática.

Published: February 2024

Dengue virus (DENV) infections after exposure in Egypt increased in Germany in 2023, with 36 cases vs zero to eight in 2017 to 2022. Over 90% of the patients had stayed on the Red Sea Coast (mostly Hurghada), almost 50% in private residences. Case numbers increased more strongly than traveller numbers. Mosquito control is more difficult in towns than hotel grounds, increasing the risk of infection at private residences. Physicians should consider dengue for unexplained fever after return from Egypt.
Діяльність українських спортсменів під час російської агресії

Published: February 2024

The article substantiates the relevance and importance of the activities of Ukrainian athletes during the russian aggression period, assistance to the Armed Forces of Ukraine (AFU), support for the development of sports and the struggle to exclude russian and belarusian athletes from participation in international competitions. Attention is drawn to the complexity of the processes of competition and training in the temporarily occupied territories due to the destruction of sports infrastructure, evacuation to other regions and outside the country.Therefore, the purpose of the study is to highlight the activities of famous athletes after Russia's full-scale invasion of Ukraine. Research Methods: theoretical analysis of social practice, methods of generalisation, comparison, review of scientific analytical sources and information from electronic resources. As the article argues and substantiates, many well-known and successful Ukrainian athletes are making a significant contribution to accelerating our victory by spreading information about the war in Ukraine and actively participating in the organisation of numerous charity fundraising projects, while making their own contributions. The importance of athletes' participation in information and volunteer activities is emphasised, helping to engage the international community in supporting Ukraine and distancing themselves from russia. By doing so, they confirm their national and patriotic position and the unity of the entire Ukrainian people against the occupiers. The dissemination of their position by leading athletes in the media, electronic networks, and at various events opens the eyes of many people abroad to russian aggression and events in our country, and debunks russia's false information attacks. The authors argue that this causes a positive perception, changes the attitude towards Ukraine and Ukrainians from indifferent to sympathetic, causing outrage at the genocide, cruelty and savagery of the aggressor and respect for our nation, as well as the readiness of many partner states to support the isolation of russian and belarusian sports structures at the international level.

Topicality. The analysis of indicators of the ability to maintain static balance of the body in children with hearing impairment, conducted by experts, shows that these indicators have statistically significant differences compared to their practically healthy peers. The Aim of the Study is assessment of the level of development of static balance of the body of children aged 7–10 years old with hearing impairment according to the test of E.Y. Bondarevskyi. 72 children aged 7–10 years with hearing impairments took part in the scientific study. Among them are girls (n = 39) and boys (n = 33). The following Methods were used to solve the tasks: analysis of scientific and methodical literature, survey, pedagogical testing, pedagogical observations, pedagogical experiment, mathematical methods. Research Results. Examination of the obtained experimental data shows that among the 7-year-old boys with hearing impairments, there were no such ones who had a sufficient level of development of static body balance (distribution according to  the  level  of  educational  achievements  of  static  body balance,  according  to E. Y. Bondarevskyi’s test, with eyes closed); in 50,0 % sufficient and in 50,0 % – the initial level of development of static balance of the body was recorded. At the same time, among the 8-year-old boys, the following distribution was observed according to the levels of static balance of the body: 12,5 % – average level, 87,5 % – initial level. The study showed that among 9-year-old boys with hearing impairments, 22,2 % are characterized by sufficient, 55,6 % – average, and 22,2 % – initial level of the studied quality. A sufficient level of static body balance was recorded in 25,0 %, average – also in 25,0 %, initial – in 50,0 % of the examined 10-year-old boys. Conclusions. In the process of conducting a pedagogical experiment, we identified distinctive features of the level of development of static balance of the body of children aged 7-10 years with hearing impairment according to the E.

Topicality. Numerous studies conducted in recent years testify to the mass character of postural disorders, indicating the negative impact of disorders of the musculoskeletal system on the state of health. The Objective of the Study is to screen the biogeometric profile of the posture of women aged 36–40. 28 women in the second period of adulthood took part in the research, among them aged 36–38 (n = 14) and 39–40 years old (n = 14). The following Research Methods were used in the study: theoretical, photography and posture analysis, pedagogical, mathematical. Results of the Study. In the course of the research, it was determined that when comparing the biogeometric posture profiles of women aged 36–38 and 39–40 years old with different types, the older age group differs only in a greater angle of inclination of the trunk. However, the dispersion analysis of the posture profiles of women, taking into account their type, made it possible to clarify that not only the angle of inclination of the trunk, but also the distance of the thoracic kyphosis, the position of the feet, the general indicators of the profile in the sagittal and frontal planes are indicative for differentiation, as well as the integrated state level indicator of the biogeometric profile of posture, which in all groups with impaired posture was lower than in individuals with normal posture. Conclusions. The results of the study showed that the groups have significant differences in the integral indicator of the level of the state of the biogeometric profile of the posture. Also to a lesser extent, however, there is an intergroup variation at the level of trends (р < 0,1) in the angle of inclination of the torso in the sagittal plane and the placement of the feet in the frontal plane. That is, there are reasons to analyze the features of the state of the biogeometric profile of the posture separately in each group of women, taking into account the age and type of posture.

Gili Air as one of the Small Islands in West Nusa Tenggara (NTB) has various geographical limitations and even has economic dependence on the tourism industry. The large number of tourists has an impact on the amount of waste generated every day. This is not balanced with optimal waste management in Gili Air, where waste from each household and tourism supporting facilities is just piled up, then taken by the transportation service (Gili Care) and disposed of in the TPA (Final Disposal Site) in Lombok Big Island. Waste management on Gili Air requires a large amount of money because you have to pay for transportation by boat. Some local people and owners of tourism-supporting facilities manage their waste by dumping it in pits or burning it. Some of them who know the economic value of inorganic waste sell directly cardboard, used bottles, iron and others to collectors or scavengers themselves. The waste bank in Gili Air has not run optimally, so the reduction in waste generation only comes from selling used goods individually. Based on these various problems, the service team carried out community service activities through outreach and training on the use of inorganic waste to become verticultural planting media which indirectly contributed to household-scale greening in Gili Air. The goal of this activity is to generate enthusiasm and participation from Karang Taruna Gili Air (KTGA) in terms of waste management. This service activity took place enthusiastically and actively involved KTGA, where the evaluation results showed that there was an increase in knowledge of 47%. The community's activeness in providing questions and responses is an asset for participatory community empowerment in Gili Air.
Tokens no fungibles (NFT) en el centro de atención legal: Examinando aspectos regulatorios y desarrollos legales
Authors: Troitskiy Vladimir
Published: February 2024

El artículo examina los tokens no fungibles (NFT) y su descripción común como representaciones digitales inmutables de propiedad o derechos sobre activos tangibles e intangibles. Desde una perspectiva legal formal, estas afirmaciones no son precisas. Aunque existen NFT que pueden considerarse valores y otorgan derechos de propiedad o control, estas situaciones son excepcionales y la mayoría de los NFT no establecen un vínculo legal con los objetos que representan.La creación, emisión y transacciones de NFT pueden tener implicaciones legales significativas en términos civiles, administrativos y penales. Es importante destacar que la interpretación generalizada de los NFT como representaciones digitales de propiedad es más una visión de su potencial futuro que una determinación precisa de su naturaleza actual.No obstante, los NFT tienen un gran potencial para convertirse en herramientas técnicas reguladas porleyes. El artículo explora cómo los NFT pueden influir en el desarrollo legal en diversos campos, incluyendo el derecho de propiedad y el derecho de autor.Dada la falta de regulación específica sobre los NFT en Paraguay, resulta especialmente relevante estudiar la experiencia y teoría legal a nivel mundial. La comprensión de los marcos regulatorios existentes en otras jurisdicciones puede proporcionar una base sólida para abordar los desafíos y oportunidades legales relacionados con los NFT en el contextoparaguayo

Authors: Benítez Cardozo Fabiola Leonor , Gómez Garozzo Mauricio
Published: February 2024

Se analiza la evolución del concepto de democracia en los discursos de los presidentes de Paraguay desde 1989 hasta 2018. Se realizó un estudio documental utilizando 14 códigos agrupados en tres categorías, que permitió identificar patrones temáticos recurrentes en los discursos presidenciales y compararlos entre diferentes mandatos. Los discursos presidenciales son un aspecto fundamental para comprender la dinámica política y social del país. Se aborda la manera en que el concepto de democracia es utilizado por los presidentes en sus discursos. Esto es relevante para comprender cómo se define y promueve la democracia en el discurso político y su impacto en la sociedad. Los resultados demuestran que los presidentes paraguayos en sus discursos conceptúan una democracia pluralista, transparente, justa y participativa con instituciones fuertes, respetadas y con acceso a la educación,la justicia, la seguridad y el desarrollo económico. También enfatizan la lucha contra la corrupción, la desigualdad y la promoción de la integración regional. Este enfoque está inscripto en la línea de análisis de discursos, no en análisis de acciones o desempeño, pero es sabido que los discursos, y especialmente los presidenciales pueden tener implicaciones en la toma de decisiones gubernamentales, aunque no es el objetivo directo de este análisis.
EXPLORING THE CHARACTERISTICS AND EFFECTS OF DATE PALM WASTE ON SOME PROPERTIES OF CONCRETE: A REVIEW
Authors: Ahmed Mahmood Fawzi
Published: February 2024

The growing concern about environmental pollution and the depletion of resources has led to a focus on the use of more sustainable materials. In light of this, the recycling and use of agricultural wastes is highly advanced and sought-after in the concrete technology field. Yearly, an enormous quantity of date palm waste (DPW) is produced, putting stress on the ecosystem and necessitating an urgent disposing method. For this reason, many researchers are looking into the feasibility of incorporating DPW for cement composites in an effort to improve the performance and sustainability of concrete. The use of DPW in the design of concrete and mortar mixes has a significant effect on both the fresh and hardened properties of the resulting composites. This paper reviews the basic information on the types and characteristics of DPW used in previous studies. In addition, the potential inclusion of DPW and its effect on cement-concrete performance are reviewed. This study further highlights the areas that need additional investigation for adopting these waste materials. This will advance academic research and benefit the sustainability of the construction industry.
Sialolithiasis in children
Authors: Putri Arihtalia Br Purba  , I Dewa Gede Arta Eka Putra
Published: February 2024

Introduction: Sialolithiasis is a disease in which calcified substances accumulate in the ducts or parenchyma of the salivary glands. This disease can occur in people of all ages but is mostly seen in middle-aged adults and rarely in children. This case report aimed to describe a case of sialolithiasis in children Case Report: A 3-year-old girl presented with a lump that enlarged progressively on the right side of the neck since 1 year ago. The patient also complained of painful swallowing. Palpation of the right submandibular revealed a solid, mobile mass measuring 0.5x0.5cm without tenderness or hyperemia. A neck ultrasound showed an enlarged submandibular gland and right parotid gland. A midface and neck multi-slice computed tomography scan (MSCT) supported the diagnosis of sialolithiasis. The patient underwent stone removal with an extraoral approach and general anesthesia. The patient then was discharged with cefixime, methylprednisolone, and paracetamol. Discussion: Sialolithiasis that cannot be removed by opening the canal can be removed by trans-oral or extra-oral sialolithotomy, extracorporeal lithotripsy, sialendoscopy, or laser treatment. Submandibular stones can be removed surgically by intraoral or extraoral approaches. Extraoral approaches are indicated for intra-glandular stones and stones embedded in the hilum of the gland. Conclusion: The diagnosis of sialolithiasis in this patient was confirmed through history taking, physical examination, ultrasound, and a CT scan. Management of sialolithiasis focuses on removing the stone and maintaining salivary gland function. In this case, the stone was removed using an extraoral approach under general anesthesia which resulted in a good outcome

The threshing cylinder rotational speed was varied at 669 and 778 rpm. The measured performance of the mini power thresher was feeding capacity, threshing capacity, cleanliness, percentage of grain not threshed, percentage of scattered grain, threshing efficiency, percentage of yield loss, fuel consumption, and increase in cracked grain. The test sample used was IR 64 rice. Based on the test results, the rotational speed of the thresher cylinder has a very significant effect on the threshing performance of the mini power thresher. Changes in threshing cylinder rotational speed from 669 rpm to 778 rpm can improve the performance of the mini-power thresher in terms of feed capacity, threshing capacity, threshing cleanliness, percentage of grain scattered, and percentage of yield loss. The decrease in performance is found in fuel consumption and the percentage of cracked grain. The variables that relatively unchanged were the percentage of grain not threshed and threshing efficiency. The operation of this mini power thresher is recommended at a thresher cylinder rotational speed of 778 rpm.

This research aims to determine the effect of the discovery learning model on the conceptual understanding of class V students at SDN Cikokol 4, Tangerang City. This research is research that uses a quantitative approach with the Quasi Experimental method. The population in this study was 87 class V students at SDN Cikokol 4 Tangerang City with a sample of 57 students divided into 30 class V A students and 27 class V B students. Data collection techniques consisted of observation sheets, test instruments and documentation. The test instruments (pretest and posttest) used are 15 essay questions each. This research was tested and analyzed using EXCEL. In the results of the posttest hypothesis test using the pooled variance model t-test formula, tcount was 7.24 and ttable was 2.00. Because tcount > ttable, it can be concluded that H0 is rejected and H1 is accepted, which means that there is an influence of the discovery learning model on understanding the concepts of science subjects. The average posttest score in the experimental class was 80.1 and 75.25 in the control class posttest class. This can show that the use of the Discovery Learning learning model increases students' understanding of science subject concepts more significantly

Hutan rakyat adalah hutan tanaman yang tumbuh di atas lahan milik rakyat atau masyarakat. Sengon (Falcataria moluccana) dan balsa (Ochroma pyramidale) merupakan jenis multi fungsi dan cepat tumbuh yang banyak dibudidayakan di Indonesia, khususnya di Pulau Jawa. Serangan penyakit hutan merupakan ancaman yang berpotensi mengganggu kegiatan budidaya kedua jenis ini, serta dapat merugikan secara ekologi, ekonomi, dan sosial. Pengenalan penyakit hutan merupakan kegiatan preventif yang sangat penting dalam pengelolaan penyakit hutan itu sendiri. Tujuan pengabdian pada masyarakat dalam “Program Dosen IPB Pulang Kampung” ini adalah sebagai upaya capacity building masyarakat sekitar hutan melalui penyuluhan, pelatihan, dan pendampingan terkait pengenalan (identifikasi) dan pengelolaan penyakit pada hutan tanaman yang ditujukan bagi para masyarakat petani hutan dan/atau pihak (stakeholder) terkait di Desa Ngancar, Kabupaten Kediri, Jawa Timur. Secara umum, program ini membantu meningkatkan pengetahuan dan pengalaman peserta dalam mengidentifikasi penyakit hutan tanaman, khususnya untuk jenis sengon dan balsa.
