Authors: Lamba Deepak , Dwivedi Durgesh Kumar , Yadav Monu , Kumar YR Sanjaya
Published: January 2024

Objective

Boldine is a plant-derived bioactive compound that has a beneficial impact on human health. Boldine is an aporphine alkaloid mainly obtained from the leaves and bark of the Chilean Boldo tree (Peumus boldus, Family: Monimiaceae). There are plenty of preclinical evidence supports that boldine exerts its beneficial effects against various diseases. Lumiskin™, a patented and marketed formulation by Revitol Skincare for skin brightening, contains Dicetyl boldine, a boldine derivative.

Content

All the available information on the Chilean boldo tree (P. boldus Molina) species was actualized by systematically searching the scientific databases (PubMed, SciFinder, Web of Science, Google Scholar, Scopus and others) and scientific literature. This article covers the recent advances in pharmacokinetic, toxicological, pharmacological/biological activities, and molecular mechanisms of the bioactive compound to understand health benefits of boldine better.

Boldine exerts antioxidant, hepatoprotective, anti-atherosclerotic, anti-diabetic, analgesic, antipyretic, anti-inflammatory, anti-epileptic, neuroprotective, nephroprotective, anti-arthritis, anticancer and nootropic effects. Moreover, boldine exhibits its various pharmacological activities by altering antioxidant parameters (MDA, superoxide dismutase, glutathione), peroxynitrite, inflammatory markers apoptotic index, caspase-3, acetyl-cholinesterase, myeloperoxidase, TNF-α (Tumor necrosis factor-α), iNOS, Bcl-2-associated X protein (BAX), ACE-1(Angiotensin-converting enzyme-1), dopamine D2 receptors and nicotinic acetylcholine receptor. Boldine has the potential to modulate a variety of biological networks.

Outlook

Due to its versatile pharmacological effects reported in various experimental animals as well as in randomized clinical trials for the treatment of facial melasma and for treatment of urinary stone lithotripsy in children as a complementary phytotherapy; in the future, this compound might be developed as a novel drug for a different indication
Factors associated with neonatal hyperinsulinemic hypoglycemia, a case-control study
Authors: Rattanasakol Thanaporn , Kitsommart Ratchada
Published: January 2024

Objectives

We aimed to identify perinatal risk factors associated with hyperinsulinemic hypoglycemia in neonates. Secondary objectives included an examination of clinical and biochemical characteristics at the time of diagnosis and an exploration of the duration of diazoxide therapy.

Methods

A case-control study was conducted, involving individual chart reviews of inborn infants diagnosed with hyperinsulinemic hypoglycemia (the HH group) between 2014 and 2021. These cases were paired with controls (the non-HH group) belonging to the same gestational age (GA) strata who did not exhibit HH or only had transient postnatal hypoglycemia.

Results

A total of 52 infants with HH were matched with corresponding controls. The mean GA in the HH group was 34.4 ± 3.1 weeks. Notably, the HH group exhibited lower mean minimum plasma glucose (PG) levels and required higher glucose infusion rates in comparison to the non-HH group (26.5 ± 15.6 vs. 49.1 ± 37.7 mg/dL and 12.9 ± 3.8 vs. 5.7 ± 2.1 mg/kg/min, respectively; p<0.001 for both). After adjusting for potential confounding factors, only two variables, fetal growth restriction (FGR) and neonatal sepsis, demonstrated significant associations with HH (adjusted odds ratio [95 % confidence interval]: 8.1 [2.1–31.0], p=0.002 and 6.3 [1.9–21.4], p=0.003, respectively). The median duration of diazoxide therapy for the HH group was 4 months.

Conclusions

FGR and neonatal sepsis emerged as notable risk factors for HH. These infants exhibited lower PG levels and necessitated higher glucose infusion rates compared to their non-HH counterparts. Importantly, a substantial proportion of the HH group received diazoxide therapy, with a median treatment duration of 4 months.
Magnetospectroscopy of shallow donors in two dimensions in the presence of fluctuations of the electrostatic potential
Authors: Karpierz Krzysztof , Szot Michał , Wojtowicz Tomasz , Łusakowski Jerzy
Published: January 2024

Spectroscopy of shallow donors is a tool to test theoretical models and to reveal properties of semiconductors. In this work we consider intra-shallow impurity transitions by studying a CdTe/(Cd, Mg)Te structure grown by a molecular beam epitaxy in which both a CdTe quantum well and (Cd, Mg)Te barries are uniformly doped with iodine donors. Measurements of a photocurrent (PC) at the far-infrared were carried out at 4.2 K and magnetic fields B up to 7 T with the energy of photons originated from a molecular laser in the range 2.2 meV–12.8 meV. Spectra (a PC signal vs. B, at a constant energy of photons) show lines which position does not depend on the photon energy but shifts with the in-plane electric field. These dependencies, which do not follow a well-established picture of shallow donor magnetospectroscopy in quantum wells, are explained within a model which unifies the role of fluctuations of the electrostatic potential and a magnetic-field induced electron localization.
Few-emitter lasing in single ultra-small nanocavities
Authors: Ojambati Oluwafemi S. , Arnardóttir Kristín B. , Lovett Brendon W. , Keeling Jonathan , Baumberg Jeremy J.
Published: January 2024

Lasers are ubiquitous for information storage, processing, communications, sensing, biological research and medical applications. To decrease their energy and materials usage, a key quest is to miniaturise lasers down to nanocavities. Obtaining the smallest mode volumes demands plasmonic nanocavities, but for these, gain comes from only a single or few emitters. Until now, lasing in such devices was unobtainable due to low gain and high cavity losses. Here, we demonstrate a form of ‘few emitter lasing’ in a plasmonic nanocavity approaching the single-molecule emitter regime. The few-emitter lasing transition significantly broadens, and depends on the number of molecules and their individual locations. We show this non-standard few-emitter lasing can be understood by developing a theoretical approach extending previous weak-coupling theories. Our work paves the way for developing nanolaser applications as well as fundamental studies at the limit of few emitters.
Impact of mulching and planting time on spring-wheat (Triticum aestivum) growth: A combined field experiment and empirical modeling approach
Authors: Alhassan Abdul-Rauf Malimanga
Published: January 2024

This study aimed to assess the effect of straw-mulching and sowing time on spring-wheat growth and also evaluate the suitability of nonlinear models (Logistic, Gompertz, Richards and Weibull models) in forecasting crop growth. The experiment followed a factorial design with two factors: three planting times (early, normal and late sowing times) at two different straw-mulching rates (3.75 t/ha straw [mulch] and 0 t/ha straw [no-mulch]). The following treatments were established from these factors: (1) early sowing without straw-mulch (ESW-T), (2) early sowing with straw-mulch (ESW-TS), (3) normal sowing without straw-mulch (NSW-T), (4) normal sowing with straw-mulch (NSW-TS), (5) late sowing without straw-mulch (LSW-T) and (6) late sowing with straw-mulch (LSW-TS). The results showed that, generally mulching improved soil water storage and enhanced biomass growth while early sowing combined with mulching (ESW-TS) gave the greatest results in terms of biomass growth. Furthermore, the logistic model was the most suitable for crop forecasting with a coefficient of determination (r
2) of 0.887 and a change in Akaike information criterion (∆AIC) of 0. The Gompertz model was next with r
2 = 0.884 and ∆AIC = 0.53, followed by the Weibull model (r
2 = 0.883, ∆AIC = 2.83). The Richards model showed the least performance (r
2 = 0.882, ∆AIC = 3.42). These results implied that the adoption of early sowing and straw-mulching could enhance soil water storage, improve wheat yields and improve climate resilience of agroecosystems on the Loess Plateau and similar dryland ecosystems. Furthermore, the logistic regression model can be a useful decision tool for testing the effectiveness of climate adaptation strategies.
Exploring the potential of Meldrum’s acid-bearing chain extenders for mechanical recycling of PET
Authors: Goksu Yonca Alkan
Published: January 2024

Poly(ethylene terephthalate) (PET) is a widely used thermoplastic polymer with exceptional properties, making it a cornerstone in various industries. However, the extensive global demand for PET, particularly in the packaging sector, has led to significant ecological concerns due to inadequate recycling rates. This paper explores the potential of Meldrum’s acid-based chain extenders as a solution to enhance PET recycling. Initially, 2,2,5-trimethyl-5-(4-vinylbenzyl)-1,3-dioxane-4,6-dione (St-MA) was synthesized, and its homopolymers were produced through free radical polymerization and characterized through 1H NMR, FTIR and TGA analyses. Dynamic interactions between recycled PET (rPET) and the synthesized chain extender (HP) in an extrusion environment was further explored, resulting in higher T
g and T
c for rPET when 0.5 wt% of HP was added as a reactive chain extender. The chemical tunability of this functional ketene-based chain extender holds promise to enhance PET recycling practices. The continuous evolution of regulatory frameworks and environmental concerns may prompt the exploration of novel approaches, such as tailored Meldrum’s acid-bearing chain extenders, which might have the potential to reduce the ecological consequences associated with post-consumer PET waste.
Seeking an optimal design of Search and Merge: its consequences and challenges
Authors: Goto Nobu , Ishii Toru
Published: January 2024

We propose that Merge, both External Merge and Internal Merge, is totally free from Minimal Search, and more specifically, Search Σ to determine the input of Merge only obeys Binarity and the Phase Impenetrability Condition but not Minimal Search (theMinimal Search-free Merge Hypothesis). We argue that our proposal provides a unified account of various movement restrictions, such as the freezing effect, thethat-trace effect, the anti-locality effect, the vacuous movement hypothesis, and the economy of derivation. We also argue that our proposal derives the insights/consequences of Minimal Yield such as ruling out so-called extensions of Merge by limiting the search space at a later stage of a derivation in terms of Binarity and the PIC. We further expand the empirical and theoretical scope of our proposal by considering exceptions to the freezing effect. We suggest that the exceptions can be dealt with by adopting Form Copy.

The calculable futureCan the future be calculated? I would like to point out that, from a practical point of view, it is simply counterfactual to give a categorically negative answer to the question. Common sense and science work in the context of calculations. The concept of causality and temporality requires a distinction between events; it assumes uninterrupted continuity and a fixed sequence of elements appearing in the continuity. I argue that in this process, there are privileged positions in terms of calculations: the present in the case of time and the cause within the causal relation.
Del bipartidismo a la fragmentación extrema: la atomización del sistema de partidos en Costa Rica
Authors: Barragán Manjón Mélany , Chavarría-Mora Elías
Published: January 2024

Después de las elecciones generales de 2002, Costa Rica ha transitado de un sistema bipartidista a otro cada vez más fragmentado. La erosión de las lealtades históricas y el desalineamiento de los partidos han generado un escenario de fluidez partidista que ha ido acompañado de un distanciamiento cada vez mayor entre partidos y sociedad. El presente trabajo identifica los principales indicadores de cambio, a partir de un análisis segmentado en el tiempo: el período de bipolaridad (1953-1986), de bipartidismo (1986-2002) y de multipartidismo (2002-presente). Estos indicadores, a su vez, son puestos en discusión con los niveles de participación electoral por parte de los ciudadanos y las percepciones de las élites respecto al papel de los partidos. Se observan pocas diferencias entre los legisladores de los viejos y nuevos partidos, aunque si se detecta que los´legisladores de los más nuevos partidos tienen una visión más pesimista con respecto a la integración entre partidos y sociedad.

Modification of the Asphalt Binder with Nano-aluminum Oxide: An Alternative to Improve the Thermal Conductivity and the Rheological Properties of the Asphalt Matrix
Authors: Broering Wellington Borba , de Melo João Victor Staub , Manfro Alexandre Luiz
Published: January 2024

This article presents the results of research that aimed to develop asphalt nanocomposites (conventional asphalt binder + nano-aluminum oxide [Al2O3]) with greater thermal conductivity and better rheological/mechanical properties, at high and intermediate temperatures, when compared to a reference matrix. The end goal was to be able to recommend a range of additional nanoparticle content to the conventional binder, establishing a direction for future investigations into the healing ability of asphalt mixtures with nano-Al2O3, both in the laboratory and in service. Conventional asphalt was modified with 1 %, 2 %, 3 %, 4 %, 5 %, and 6 % of nano-Al2O3 content in relation to the mass of the binder. Tests with a conductivity meter and a dynamic shear rheometer were performed on the developed nanocomposites. Rheological parameters related to susceptibility to permanent deformation and tolerance to fatigue damage were specially analyzed. As main findings, the addition of nanoparticles increased the thermal conductivity of the binder at the rate of 0.004 W/mK/%nano, improved the rheological parameters of asphalt at high temperatures (susceptibility to permanent deformation) for any incorporation content between 1–6 %, and impaired fatigue damage tolerance (at 20°C) with percentages greater than 3 %. The main conclusion of this research is that nano-Al2O3 can increase the thermal conduction capacity of the matrix and improve the rheological performance of the conventional binder, at high and intermediate temperatures, with certain percentages of incorporation (1–3 %). Finally, for future studies with asphalt mixtures, an additional range of nano-Al2O3 in the conventional binder from 1–3 % is recommended.
A Modular Implementation to Handle and Benchmark Drift Correction for High-Density Extracellular Recordings
Authors: Garcia Samuel , Windolf Charlie , Boussard Julien , Dichter Benjamin , Buccino Alessio P. , Yger Pierre
Published: January 2024

High-density neural devices are now offering the possibility to record from neuronal populations in vivo at unprecedented scale. However, the mechanical drifts often observed in these recordings are currently a major issue for “spike sorting,” an essential analysis step to identify the activity of single neurons from extracellular signals. Although several strategies have been proposed to compensate for such drifts, the lack of proper benchmarks makes it hard to assess the quality and effectiveness of motion correction. In this paper, we present a benchmark study to precisely and quantitatively evaluate the performance of several state-of-the-art motion correction algorithms introduced in the literature. Using simulated recordings with induced drifts, we dissect the origins of the errors performed while applying a motion correction algorithm as a preprocessing step in the spike sorting pipeline. We show how important it is to properly estimate the positions of the neurons from extracellular traces in order to correctly estimate the probe motion, compare several interpolation procedures, and highlight what are the current limits for motion correction approaches.
En busca del autor de “El contrabando de El Paso”
Authors: Hernández Guillermo E.
Published: January 2024

The ballad (corrido) “El Contrabando de “El Paso,” widely sung along the U.S. Mexican border since 1928, is now considered a classic of the genre. The narrative portrays the journey of a group of prisoners transferred from the city jail in El Paso, Texas, to the federal penitentiary in Leavenworth, Kansas. Most of these convicts were serving sentences related to the violation of laws prohibiting the possession and sale of alcohol and narcotics. Speaking in first person, the narrative voice comments on the hardships endured by the prisoners and laments the misfortunes suffered by the smugglers. This study, following modern trends in the study of the corrido, accentuates the historical basis of the corrido, examines the circumstances surrounding the event—such as its date (August 7–9, 1924) and the names of the convicts—and suggests the identity of its most probable composer. The evidence presented—circumstantial and interpretative—points to a man named Gabriel Jara Franco as the likely candidate for its authorship. Particularly compelling is Jara’s record at Leavenworth, which lists his substantial correspondence with Leonardo Sifuentes. Sifuentes was part of the Hernández y Sifuentes Duet, who, in 1928, recorded the first known version of “El Contrabando de El Paso.”

Published: January 2024

Low carbon-to-nitrogen (C/N) ratios are the main characteristic of domestic wastewater. In this study, we evaluated the nitrate removal characteristics of Pseudomonas sp. XS-18 at low C/N ratios (4.0 and 6.0) and pH 11.0. We also analyzed the causes of the nitrate removal at low C/N ratios in this strain. At pH 11.0 and a C/N ratio of 4.0, the strain was effective in removing nitrate. Additionally, the total organic carbon content decreased over time at low C/N ratios, requiring more energy to complete vital activities. Furthermore, low C/N conditions resulted in less strain secretion compared to high C/N settings, and the polysaccharide content degraded more quickly than protein over time. To provide a carbon source for the nitrate reduction process, strains with low C/N ratio and high pH secreted more soluble microbial by-products. This strain is able to metabolize its own secreted extracellular polymeric substances as a carbon source to enhance nitrate removal.

The purpose of this study was to purify hyodeoxycholic acid and chenodeoxycholic

acid from pig bile saponification solution using column chromatography. The optimal

resin was selected through static adsorption experiments. Loading, washing, and elution

conditions were optimized. Hyodeoxycholic acid and chenodeoxycholic acid were further purified through crystallization. The best resin was found to be CG161M macroporous resin. After optimization, the sample was loaded at a volume flow of 3 BV h–1 to adsorb 5 BV, washed with 40 % ethanol, eluted with 45 % ethanol and 60 % ethanol, respectively. This resulted in purities for hyodeoxycholic acid of 70.34 % and 66.21 % for chenodeoxycholic acid with yields of 86.48 % and 90.57 %, respectively. Crystals of hyodeoxycholic acid with a purity of 91.04 % and chenodeoxycholic acid precipitate with a purity of 80.28 % were obtained through crystallization. Hyodeoxycholic acid and chenodeoxycholic acid can be purified using CG161M resin, and subsequent crystallization yields high-purity hyodeoxycholic acid.

Exposure to local history can help students bridge their understanding of historical events in the surrounding community and foster their interest in learning history. The purpose of this paper is to describe how teachers instill historical values in Kudus Regency among students, delineate students' memories of the history of Kudus Regency, and analyze the extent of students' historical awareness regarding the historical heritage of Kudus Regency. This study employs a descriptive qualitative approach, with the research conducted at SMA NU Al Ma'ruf Kudus. The findings of this paper suggest that, in instilling local historical values in Kudus district, the initial strategy employed by teachers is to capture students' interest first and then provide knowledge, including information about key figures who spread Islam in Kudus, da'wah, teachings, and historical heritage in Kudus. Students' memory of the local history of Kudus district is closely associated with Islamic history. Children from Islamic boarding schools, in particular, have a better understanding of the value of tolerance, as they grasp the meaning behind the prohibition of slaughtering cows—a teaching that originated in Kudus when Islam entered the region. Other students are familiar with the figures who spread Islam in Kudus and the methods employed by each of these figures in their preaching.

Published: January 2024

Understanding concepts is essential in physics education, as this subject emphasizes the practical application of concepts over rote memorization. This approach helps prevent students from occurring misconceptions. Moreover, learning motivation can raise enthusiasm for learning physics to achieve the expected goals. However, evidence suggests that both variables show low levels. Therefore, this study aims to develop valid, practical, and effective Engklek game ethnoscience-based edutainment learning materials (EGEBLM) to improve students' physics concept understanding and learning motivation. This research utilizes the 4D type (Define, Design, Develop, Dissemination) to fulfill the quality test of the developed learning materials. The sample of this study involved 29 high school students at level XI. The EGEBLM test design used a non-equivalent control group design. Data were analyzed using descriptive and statistical tests, including N-gain, t-test, and MANOVA. The results reveal that EGEBLM is declared valid in content and construct in each component, including syllabus, lesson plans, teaching materials, student worksheets, test instruments, and response questionnaires. Observations indicate that each learning approach's syntax can be effectively implemented ( 3.00), rendering it suitable for educational applications. EGEBLM also meets effective criteria based on descriptive and statistical tests (p 0.05) to enhance conceptual understanding and learning motivation, receiving positive feedback from students to this learning. This learning model combines collaborative discovery learning activities with traditional Engklek games that they have applied everyday, enabling students to understand physics concepts easily and meaningful learning experience. This research has implications as an innovative method in learning physics edutainment, offering an accessible, cost-effective, enjoyable approach while also preserving the Engklek cultural context.

Authors: Danurrachman Y. , Maryono M. , Muhammad F. , Soeprobowati T. R. , Van der Maas P.
Published: January 2024

The estuary, downstream of the river, accumulates pollutants from upstream and marine. Tuntang is one of the major rivers in Central Java, 139 km length from Rawapening Lake, and ends in the Java Sea. Mangroves are the dominant riparian vegetation in the downstream and estuary of the Tuntang River. This research analyzes the water quality and pollution index (PI) of Tuntang Estuary, Demak. Water samples were collected from four sites in February (wet season) and September 2022 (dry season) and were analyzed for temperature, TDS, pH, BOD, COD, DO, nitrate, nitrite, ammonia, TN, TP, Cd, Cu, Pb, Cr, fecal coliform, and total coliform. The water quality parameters of Tuntang Estuary in the dry season exceeded the threshold for Class I-III, such as TDS in T1 ((2530 mgL-1), BOD (4.06-5.12 mgL-1), COD (28.32-102 mgL-1), DO for Class I and II (3.93-4.28 mgL-1), Pb at T1 and T3 in the wet season, and T1 in the dry season, and Cr for Class I, II, and III (. 0.05 mgL-1), Pb (T1), and Cr for Class I, II, and III (. 0.05 mgL-1). In contrast, in the wet season, BOD (4.37-7.15 mgL-1), Pb (T1 and T3), fecal coli, and coliform exceeded the threshold. The TN (0.83-2.48 mgL-1) and TP in the wet season (0.45-0.53 mgL-1 at T1 and T1) indicated that Tuntang Estuary was in the eutrophic condition. Based on the PI method, the water quality of Tuntang Estuary is good to slightly polluted for Class I, II, and III. The sustainable river management that is appropriate to be developed for the Tuntang River is conserving the mangrove ecosystem in the Tuntang Estuary.
Legal Dynamics of Limited Liability Companies: Unveiling the Power of Commissioners and Shareholders to Take Legal Action Against Directors' Negligence
Authors: Sufiarina Sufiarina , Ali Muhammad , Mufrina Mufrina , Maulana Ahmad , Tia Hendry Frand
Published: January 2024

The Limited Liability Company (LLC) is characterized by its distinct juridical entity, effectively segregating its management group from shareholders. Operating as a business entity, the primary goal of an LLC is profit generation. Functioning as a corporate legal entity with legal personality, an LLC comprises three key organizational components: the General Shareholders’ Meeting, Directors, and Commissioners. Directors, or the Board of Directors (BOD), bear the responsibility of managing and representing the LLC both within and outside the legal realm. The position of BOD is mandated to be occupied by a natural person, or 'naturlijk person,' either as a single individual (Director) or collectively by two or more individuals (Board of Directors). Despite a stringent selection process for board positions, the inherent nature of directors as natural persons introduces the possibility of intentional or negligent errors in management, potentially leading to financial losses. In the face of such negligence, the pertinent question arises: can a commissioner (Board of Commissioners) and/or shareholders initiate legal action against a director or BOD, whose legal standing is as the company’s representative? To address this query, a comprehensive library research initiative is undertaken, focusing on the analysis of Article 97 and Article 98 of the Limited Liability Company’s legal statutes. This examination aims to elucidate the viable courses of action that can be pursued against the company in the event of directorial negligence. The research findings reveal that specific commissioners and/or shareholders, in the absence of a director's power of attorney, are granted the authority by the LLC’s legal statutes to initiate legal proceedings against the director or board of directors in a court of law.
Practice of Applying Affidavits in Bankruptcy Law and Postponement of Debt Payment Obligations
Authors: Leonardus Rado Fridsel , Yudha Alexander Yovie Pratama , Wijayanta Tata
Published: January 2024

Civil law regulates the means of evidence as outlined in Article 1866 of the Civil Code/Article 164 HIR/Article 284 RBg which consists of written evidence, witness evidence, allegations, confessions and oaths. The existence of an Affidavit certainly makes it easier to resolve a Civil Case, especially in cases regarding Bankruptcy and Postponement of Debt Payment Obligations. The existence of an Affidavit is one aspect that confirms that the process of proving a legal problem in Indonesia is undergoing adjustments in line with the very rapid development of law in this Era of Globalization. The application of Affidavits in Bankruptcy and PKPU legal processes is important in their development. This research uses Normative Legal Research using the method of the Statute Approach. Article 299 of Law Number 37 of 2004 concerning Bankruptcy and Postponement of Debt Payment Obligations explains that the procedural law that applies in resolving Bankruptcy cases and Postponement of Debt Payment Obligations is Civil Procedure Law. Written evidence is significant in the Bankruptcy Law and PKPU process, although the process still prioritizes simple evidence. Affidavit is a written statement by someone who is considered an expert containing an explanation of a particular event object, which is then signed and submitted as written evidence in the trial. In Indonesia, an Affidavit cannot be classified as an Authentic Deed and does not have perfect evidentiary properties, but an Affidavit can be used as ordinary documentary evidence to support other evidence and help judges decide Bankruptcy & PKPU cases efficiently in order to support a simple evidentiary process and considering the short examination time.
La concepción económica en la arqueología marxista peruana: paradojas y posibilidades

Este artículo es una revisión general de las propuestas económicas de los más destacados arqueólogos marxistas peruanos, teniendo en consideración el marco teórico utilizado, la coherencia conceptual de sus formulaciones y sus consideraciones metodológicas. Se hará un balance de estas propuestas en relación con el marxismo clásico, en donde se pondrá en evidencia que los arqueólogos adscritos al materialismo histórico no han tenido en el centro de su reflexión teórica al marxismo como una problemática y posibilidad, sino como una serie de conceptos económicos muy generales que propiciaron la construcción de una narrativa genérica sobre las sociedades andinas.

Introduction: Patient safety remains a major concern in the operating room (OR). The surgical checklist (CL) is presented as a solution for reducing postoperative complications by ensuring better patient safety, but the adoption and use of this tool remain modest in our ORs. So, we aimed to describe CL use practices and perceptions among OR professionals at the University Hospital Center (UHC) of Sahloul, Sousse in 2023. Methods: This was a cross-sectional study among OR professionals at UHC of Sahloul. Data were collected using a questionnaire and an observation grid. Results: The average age of respondents was 38.05 (±8 years) with a female predominance. Our results revealed positive perceptions (98.7%) regarding the usefulness of the surgical CL. Some difficulties were raised by participants, notably the difficulty of accepting verbalization aloud (59.4%), the anxiety generated by multiple checks for the patient (58.8%) and the difficulty of implementing CL during emergency interventions (49.4%). The observation grid revealed the rate of CL use in the OR (70.8%) and inadequate practices in the quality of CL item completion: Variation in the quality of CL item completion from one stage to the next; Items mostly ticked without verification, with only the patient identification (69.1%), procedure site (64.7%), known allergy (47.1%) and antibiotic prophylaxis (61.8%) items being checked aloud. Conclusion: CLs in the operating room are essential to guarantee safe, quality care. It is therefore essential that healthcare professionals, healthcare establishments and decision-makers not only recognize its importance, but also implement the necessary measures for its adoption and systematic use.

Sugar contains radionuclides and its consumption may result in an increase of the internal dose in humans. Thus, this work evaluates the profile and activity of radionuclides present in 4 VHP sugar samples obtained from producers from 4 cities in Brazil, located in the Southeast and Midwest regions: Pirajuba (State of Minas Gerais), Edeia (Goiás), Pitangueira (São Paulo) and Mendonça (São Paulo). The samples were collected between the years 2019 and 2020. The analyzes were performed by gamma spectrometry using a hyper pure germanium semiconductor detector (HPGe) counting the samples over a period of 24 hours. The same profiles of radionuclides 226Ra, 212Pb, 214Bi, 40K were observed in all samples, except for the sample from Mendonça, which presented a low counting rate for 214Bi. Calculations of specific activity were carried out for the two most abundant radionuclides, 226Ra and 40K, obtaining the following values (in Bq kg-1): for 226Ra Pirajuba (22.43 Bq kg-1), Edeia (22.38 Bq kg-1), Pitangueira (18.25 Bq kg-1) and Mendonça (36.16 Bq kg-1) and for 40K Pirajuba (0.66 Bq kg-1), Edeia (0.99 Bq kg-1), Pitangueira (0.66 Bq kg-1) and Mendonça (0.33 Bq kg-1). Additionally, the values ​​of total absorbed dose rate were calculated: ​​Pirajuba (43.61 nGy h-1), Edeia (43.60 nGy h-1), Pitangueira (41.82 nGy h-1) and Mendonça (49.45 nGy h-1). Therefore, according to the United Nations Scientific Committee on the Effects of Atomic Radiation, the results obtained did not show a significant transfer of absorbed dose due to radionuclides from sugar consumption under the conditions adopted in this work. No variation of radiation dose according to the region or year of production was observed.

Published: January 2024

This study explores the impact of corrosion on Ground Penetrating Radar (GPR) responses through practical experiments and numerical modelling, focusing on rebar diameter reduction, corrosion product layer thickness, crack formation and corrosion product filling in vertical and transverse crack. Practical experiments involved GPR testing of reinforced concrete slab. By analyzing B-scans we identify areas with moderate and severe corrosion. Numerical modelling using the Finite Difference Time Domain (FDTD) Method to model GPR signal propagation in a concrete bridge deck with corrosion is applied. Key finding includes a significant 26.70% increase in reflected wave amplitude when corrosion product filling in vertical crack increased by 400%, highlighting its extensive effect on signal GPR propagation. Reduced rebar diameter led to a 9.79% amplitude decrease and a 0.06 ns arrival time delay. Increased corrosion product layer thickness primarily affected arrival time with a 0.06 ns extension but significantly amplified GPR signal amplitude. These findings offer insights for improving GPR based corrosion detection and assessment methods, leading to more robust systems for concrete bridge deck inspection and maintenance. This paper contributes to understanding how corrosion affects the signal that is detected by GPR. This information can be used to improve the way that we manage and assess corrosion in concrete bridge deck.

Polycystic Ovary Syndrome (PCOS) is a hormonal, endocrine, and metabolic disorder in women of reproductive age. This is characterized by symptoms such as hirsutism, menstrual disorders and infertility, affecting almost 20% of women. In this context, the syndrome affects the physical and psychological disorders of women. Conditions that predominate in PCOS women cause depression and affect their quality of life. Using a phenomenological approach, in-depth interviews were conducted to determine quality of life in six PCOS women. The participants were recruited using purposive sampling from PCOS Fighter Indonesia community in the Bandung area. Furthermore, three themes were developed from the analysis, namely positive thinking, healthy behavior and social support. This resarch showed the favorable facets of the experiences of women coping with PCOS and showed the important role of the community in offering support to individuals affected by the syndrome. The identified themes emanated from interviews exploring quality of life among women with PCOS, providing insights into their daily lives and the challenges posed by the symptoms.
