O ANTIGO E O NOVO CANGAÇO SOB A PERSPECTIVA DO BANDIDTISMO SOCIAL
Authors: DAMACENA PESSOA MATHEUS 
Published: December 2024

O presente trabalho tem como objetivo investigar pontos de divergência e de convergência entre o antigo e o novo cangaço, estabelecendo correlações entre este último e a ideia de banditismo social na análise histórica de Eric Hobsbawm. Ao longo do texto, verificou-se que apesar de carregar nomes similares, o novo cangaço não apresenta mais muitas das principais características do cangaço em sua acepção clássica, assim como era conhecido no final do século XIX e início do século XX. Logo, em razão da perda dessas características, o novo cangaço não possui os atributos necessários para se enquadrar como prática associada ao banditismo social, ou seja, aquele movimento social capaz de abalar as estruturas sociais vigentes, sendo movido por ressentimentos de classes e opressão.

Study of the Co2 Hydrogenation Reaction for the Synthesis of Alcohols on Cu and Co-based Catalysts
Authors: de Oliveira Francisco Marcelo dos Santos , Gomes Janaina Fernandes 
Published: December 2024

Abstract

Carbon dioxide (CO2) is the main gas responsible for the greenhouse effect. Anthropogenic activities have increased the concentration of this gas in the atmosphere in recent years, intensifying the greenhouse effect and resulting in anomalous climate phenomena. CO2 recycling technologies have been developed with the aim of reducing the impacts of this gas on climate change. Catalytic hydrogenation of CO2 for the generation of products of commercial interest, such as methanol (CH3OH) and ethanol (C2H5OH), for example, is a technology that has attracted the attention of recent research, given the wide industrial applicability of these alcohols and the possibility of carbon recycling. In the present study, CO2 hydrogenation reaction was investigated to produce alcohols using catalysts based on cobalt, copper and a combination between cobalt and copper. It was observed that CuO-Co3O4-Al2O3 catalysts with different Co:Cu mass ratios have improved methanol productivity when compared to CuO-Al2O3 or Co3O4-Al2O3. Furthermore, the promotion of Co3O4-Al2O3 by 2 wt.% Na, K, Rb or Cs showed better catalytic performance for the formation of ethanol, increasing its productivity up to 25 times compared to the non-promoted cobalt catalyst. The highest ethanol productivity in the present work, corresponding to 5.3 µmol/gcat.h, was achieved using the 2 wt.% K-Co3O4-Al2O3 catalyst under the reaction conditions of T = 220 °C, P = Patm and GHSV = 24,000 mL/gcat.h.

Abstract

This paper presents a compact and high-performance piezoelectric Micro-Electro-Mechanical System (MEMS) Fast Steering Mirror (FSM) designed for use in laser Inter-Satellite Links (ISLs). The FSM features a large optical aperture of 10 mm and is batch fabricated using an 8-inch wafer-level eutectic bonding process, packaged into a volume of 26 × 22 × 3 mm3. Notably, the piezoresistive (PZR) sensor is integrated on the spring of the FSM to facilitate precise beam control. Furthermore, an intermediate directional defect structure is novelly designed to create a Stress Concentration Region (SCR), effectively improving PZR sensitivity from 3.3 mV/(V·mrad) to 5.4 mV/(V·mrad). In this article, various performance metrics of the FSM are tested, including the mechanical characteristics, PZR sensor properties, and mirror optical quality, which all meet the requirements for laser ISLs. Results indicate that the FSM achieves a high resonant frequency (>1 kHz) and a low nonlinearity of 0.05%@±2.1 mrad. A remarkable minimum angular resolution of 0.3 μrad and a repeated positioning accuracy of 1.11 μrad ensure exceptional pointing precision. The open-loop control is driven by the double-step algorithm, resulting in a step response time of 0.41 ms and achieving a control bandwidth over 2 kHz. Additionally, the integrated angular sensor demonstrates a nonlinearity of 0.09%@±1.05 mrad, a sensitivity of 5.1 mV/(V·mrad), and a minimum angular resolution of 0.3 μrad. Under quasi-static driven conditions (500 Hz @±2 mrad), the maximum dynamic deformation of the mirror surface is merely 2 nm.

Abstract

Spontaneous two-photon emission is a process in which the transition between two quantum states happens via simultaneous emissions of two identical photons. Such second-order quantum radiation is of paramount importance in astrophysics, atomic physics, and quantum technology. In particular, on-demand spontaneous two-photon emission from single quantum emitters has long been envisioned to revolutionize photonic quantum science and technology. To date, experimental realizations of two-photon emission at the single quanta level are still highly challenging yet elusive due to their low probabilities. In this work, we explore spontaneous two-photon emission from a single semiconductor quantum dot deterministically coupled to a high-quality microcavity in which the cavity resonances greatly enhance both excitation and emission processes. When the cavity is resonant to the half energy of the biexciton, the strong vacuum field in the cavity mode drives the biexciton to the ground state and simultaneously emits two photons into the cavity mode, resulting in two-photon emissions with a record brightness comparable to the competing single-photon process and sub-nanowatt power consumption. For the first time, the quantum nature associated with spontaneous two-photon emissions in the cavity quantum electrodynamics regime has been investigated via photon statistics measurements. Furthermore, spontaneous two-photon emission is exploited to build unconventional entangled quantum light sources with the unique advantage of combining the best of two worlds: near-unity entanglement fidelity for spontaneous parametric down-conversion source and on-demand photon emissions for atomic quantum emitters. Our work provides unprecedented insights into the two-photon process in the quantum regime and opens an unexplored avenue for pursuing optically reconfigurable quantum light sources with nonlinear quantum radiations.

Abstract

Human plasma is routinely collected during clinical care and constitutes a rich source of biomarkers for diagnostics and patient stratification. Liquid chromatography-mass spectrometry (LC-MS)-based proteomics is a key method for plasma biomarker discovery, but the high dynamic range of plasma proteins poses significant challenges for MS analysis and data processing. To benchmark the quantitative performance of neat plasma analysis, we generated a multispecies sample set based on a human tryptic plasma digest containing varying low level spike-ins of yeast and E. coli tryptic proteome digests, termed PYE. The sample set was distributed across twelve different sites and analysed on state-of-the-art LC-MS platforms in data-dependent (DDA) and data-independent acquisition (DIA) modes, resulting in a total of 1,116 individual LC-MS runs. Centralized data analysis showed that DIA methods outperform DDA-based approaches regarding identifications, data completeness, accuracy, and precision. DIA achieved excellent technical reproducibility, as demonstrated by coefficients of variation (CVs) between 1.5% and 4.6% at protein level. Comparative analysis of different setups clearly shows a high overlap in identified proteins and proves that accurate and precise quantitative measurements are feasible across multiple sites, even in a complex matrix such as plasma, using state-of-the-art instrumentation. The collected dataset, including the PYE sample set and strategy presented, serves as a valuable resource for optimizing the accuracy and reproducibility of LC-MS and bioinformatic workflows for clinical plasma proteome analysis.

Abstract

Pesticide residues have always been one of the food safe issues troubling consumers. Agricultural production is usually accompanied by a mixture of pesticides, and pesticide residues are not only present on plants but also contaminate soil in the environment. In this study, 15 pesticides commonly found in cowpea and soil were analyzed by optimizing QuEChERS and combining GC-MS/MS and HPLC. Various extractants and different methanol water ratios were evaluated to extract the pesticides from cowpea and soil.C18, PSA and GCB were used to purify the cowpea extracts, while in soil the ratios of de-watering agent and NaCl were optimized. The average recoveries were 91.81-109.95% and 89.89-104.08% in cowpea and soil at spiked levels of 0.0-1.0 mg/kg and 0.1-10.0 mg/kg, respectively. This method is suitable for the detection of pesticides in different types of soil (red soil, yellow soil, sandy soil, sandy loam soil, paddy soil) and different cowpea tissues. In addition, pesticide residues were detected and analyzed in the cowpea- sandy loam soil system. This demonstrates that the developed method can be used to detect the multiple pesticide in various types of soils and crops, and provides the necessary technical support for agricultural product pesticide detection and safety supervision.

Published: December 2024

Abstract

Background: The electrocardiogram is the diagrammatic representation of the heart’s electrical activity. Which can detect life-threatening conditions within minutes. It’s one of the major investigative modalities that emergency physicians should be accurate at. The accuracy of emergency residents varies from country to country, with improvement in interpretation as the year of residency increases. There have been no published papers on ECG interpretation among emergency residents up until now, but a study that was done on graduating medical students shows low competency.
Objective: To assess the accuracy of Emergency and Critical Care Medicine residents in ECG interpretation at Tikur Anbessa Specialized Hospital and Saint Paul Millennium Medical College.
Methods: A cross-sectional study was conducted on emergency and critical care medicine residents of Tikur Anbessa Specialized Hospital and Saint Paul Millennium Medical College. Data were collected from April 2021 to September 2021 using a structured questionnaire. Data were entered, cleaned, edited, and analyzed using SPSS version 26.0 statistical analysis software. Descriptive statistics and bivariate and multivariate binary logistic regression were used to analyze the data.
Results: Fifty-seven emergency and critical care medicine residents were able to participate in this study, out of which 33 (57.9%) were from Addis Ababa University and 24 (42.1%) were from Saint Paul Millennium Medical College. The average score of EMCC residents on the interpretation of the ECGs was 29.5%. Only ten residents (17%) were able to correctly interpret >50% of the ECGs. Most of the residents who participated in this study were year 1 residents (49.1%), followed by year 2 residents (31.2%). Out of 15 ECG abnormalities, the commonly identified ones were polymorphic ventricular tachycardia (64.9%), normal sinus rhythm (49.1%), and double chamber pacemaker (45.6%). Year of residency (AOR 3.34, 95% CI: 1.1, 10.2) was found to be significantly associated with higher performance in ECG interpretation.
Conclusion: According to this study, emergency medicine and critical care residents have low accuracy in the interpretation of ECG, which is comparable to a study that was done in South Africa and Australia.

Abstract

In order to enhance the service performance of aviation gear oil. This work studied the effect on the cooling performance of aviation gear oil with nanodiamonds (NDs) as additives. Different contents (0.05 wt.%, 0.10 wt.%, 0.20 wt.%, 0.30 wt.%, 0.60 wt.%) of NDs were added into aviation gear oil, and different dispersants were used to disperse the NDs, which were compounded into highly dispersible NDs gear oils. Temperature rise tested by thermostatic water bath device. Molecular modeling to simulate the microscopic mechanism of nanodiamonds interaction with gear oil. The results showed that nanodiamonds could effectively enhance the cooling performance of aviation gear oil. The cooling performance was better with the increase of NDs content, which tended to stabilize at 0.6 wt.%. It was improved by 22.87% relative to the control. The longer the dispersion time, the worse the cooling performance of NDs gear oil. The interfacial bonding between the NDs molecules and the oil molecules enhanced the cooling rate of the gear oil. This study revealed the intrinsic mechanism of nanodiamonds as additives to enhance the cooling performance of gear oil. It provided theoretical guidance for the application of aviation gear oil and provided guarantee for the smooth operation of aviation equipment.

Abstract

Traditional Chinese Medicine (TCM) has gained considerable attention as a holistic healthcare approach, yet its complexity poses significant challenges for automated question-answering systems. This paper presents a novel method utilizing large language models (LLMs) to improve TCM-related QA by implementing a multi-turn prompt design. Our approach systematically guides LLMs through context-rich interactions that enhance their ability to understand and articulate TCM concepts. We conducted comprehensive experiments comparing our method against baseline prompting techniques and the Chain of Thought (CoT) approach across three state-of-the-art models: ChatGPT, Claude2, and GPT-4. Results demonstrated a significant improvement in response accuracy and contextual relevance, confirming the effectiveness of our prompting strategy. Our findings highlight the potential of advanced AI techniques in promoting the integration of TCM into modern healthcare practices.

Published: December 2024

ABSTRACT

The Water–Energy–Food–Ecosystem (WEFE) nexus highlights the interconnections between water, energy, food, and ecosystems. This study examines climate change's impact on precipitation and temperature in the semi-arid Sakarya Basin, assessing WEFE nexus vulnerability in the 21st century. Climate scenarios (RCP 4.5 and 8.5) from CCSM4 and MIROC5 were downscaled to 18 km grids for three periods (2020–2030; 2055–2065; 2090–2100) using the Weather Research and Forecasting Model (WRF). The assessment integrates these downscaled data with a range of socio-economic and environmental indicators across seven subbasins. In the most arid, agricultural subbasin, a 22% reduction in precipitation and a 2.9 °C temperature rise are projected. The most populous subbasin may face a 30% precipitation decline and a 3 °C temperature increase. A subbasin, crucial for hydroelectric power, could see a 14% precipitation decrease and a 3 °C temperature rise. These subbasins are identified as the most vulnerable in terms of agricultural productivity, municipal water demand, and energy generation, highlighting significant WEFE nexus challenges. Additionally, the ecosystem sector is highly vulnerable when evaluated against environmental flow parameters. Insights from this study will guide strategies to enhance WEFE nexus resilience in the Sakarya Basin and similar regions under changing climates.
Piper betle: Ancient Remedies and Modern Neuropharmacological Insights
Authors: Chowdhury Sejuti Ray , Ghosh Sourav 
Published: December 2024

Abstract:
The traditional use of medicinal plants holds a wealth of ancient wisdom that inspires
modern research. Piper betle, generally recognized as betel leaf, is valued in traditional medicine
systems across various cultures for its diverse health benefits. The betel leaves have several significant
uses as antioxidant, anti-inflammatory, and antiapoptotic activity which help in neuroprotection.
Many phytochemicals are present in the betel leaves, including hydroxychavicol, caryophyllene,
eugenols, tannins, and polyphenols, which have positive activity on neurological and
other cognitive impairments. Some studies have shown that Piper betel has a cholinergic activity
that directly decreases the butyrylcholinesterase (BChE) and acetylcholinesterase (AChE), which
are significantly associated with reduced levels of Acetylcholine (Ach) levels in cholinergic dysfunction.
This review article delves into the historical significance of Piper betle in traditional
medicine and its relevance to contemporary neuropharmacology. By revisiting the age-old wisdom
surrounding Piper betle, we aim to uncover its potential as a valuable source of natural neuropharmacological
agents for various neurological conditions.
