O ecoturismo é um segmento que auxilia na conservação dos espaços naturais e sua biodiversidade. Entendendo-se a complexidade das paisagens naturais, buscou-se uma análise transversal que cotejasse respostas por meio de métodos de sensoriamento remoto e métricas da paisagem. A área de estudo foi o Parque Estadual Serra do Intendente (PESI), localizado na Serra do Espinhaço. Foram utilizadas imagens dos satélites Landsat 5 e 8, dos anos de 1990 e 2020, que possibilitaram a elaboração dos mapas de uso e cobertura da terra, com qualidade temática em acurácia global de 99,7% e 86,5% e índice Kappa de 99,6% e 80,0%. As métricas da paisagem indicaram um aumento de 53,3% para 57,7% na ocorrência dos campos rupestres, uma redução dos campos graminosos (23,7% para 14,5%) e de solo exposto (0,6% para 0,1%) que, possivelmente, estão associados às áreas anteriormente ocupadas pelo gado, e um aumento da área de floresta estacional semidecidual (21,8% para 27,6%). Ao cruzar os mapeamentos e os resultados quantitativos, foram obtidos subsídios para melhor entendimento da organização espacial. Diante das análises, conclui-se que houve um aumento das formações naturais, consoante com as funções de conservação do PESI, resultando no aumento da potencialidade do ecoturismo.

Published: April 2023

This study aims at building a checklist used for each stage of wearable Elbow Exoskeletons development. The Wearable Elbow Exoskeleton is one of the handstroke therapy aids which was developed by Diponegoro University. The product is still in the form of a prototype so some tests must be carried out before the product is tested on respondents. The test so far is still focused on functionality tests. This study provides a general checklist for ergonomics testing of stroke therapy aid products. The method of the checklist is developed based on an exploratory study and literature review for producing appropriate tests related to product characteristics. There are three iterations of product development and each version repairs the previous version. The implementation of the checklist shows that on the third iteration, the product is aligned with the objective of development and reaches the targeted level of respondents’ satisfaction.

Study on CO2 absorption performance of ternary DES formed based on DEA as promoting factor
Authors: Shi Shengyou , Li Shuie , Liu Xiangwei , Liu Chengfang 
Published: April 2023

Abstract
In this study, we used tetraethylammonium chloride (TEAC), diethanolamine (DEA), and N-methyldiethanolamine (MDEA) to prepare ternary DES and binary DES to absorb CO2. We found that their formation was due to the hydrogen bond interaction between hydrogen bond acceptor and hydrogen bond donor (HBD). Surprisingly, TEAC/MDEA/DEA can react with CO2, but TEAC/MDEA cannot react with CO2. Unexpectedly, after adding DEA to TEAC/MDEA, the ternary TEAC/MDEA/DEA DES can react with CO2. Nuclear magnetic resonance spectroscopy and Fourier infrared spectroscopy results showed that the accidental CO2 absorption behavior mainly depended on the HBD DEA, because the imine group in DEA reacted with CO2 to form carbamate, thereby absorbing CO2, while the hydroxyl group on MDEA and the hydroxyl group of DEA did not interact with CO2. Through thermal stability analysis, TEAC/MDEA/DEA system with the molar ratio of 1:3:4 is more stable. We further studied the influence of molar ratio, temperature, water content, and other factors on the absorption of CO2 by ternary DES. In addition, TEAC/MDEA/DEA (1:3:4) was regenerated at 80°C, and the absorption capacity of DES was almost unchanged after five absorption–desorption cycles.
Philosophical Objections to Media Contexts of Terraforming
Authors: Sámelová Anna 
Published: April 2023

Abstract
This theoretical study focuses on terraforming in the context of the industrially created image of the world by the mainstream media and on philosophical objections to the terraforming activities of humanity. The first part discusses the specific nature of the spectacularism of media images, while the second part explains the paradigmatic change in media images. The third part then turns to the ethically grounded binarism of current philosophical reflections on human expansion into space. The purpose of this study is to consider objections to the mainstream media focus from the viewpoint of contemporary philosophy. The theoretical reflection is based on induction and deduction in order to point out the ambivalence of what humanity can do in the framework of progress in the sense of what it is capable of and in the sense of what is right.

Published: April 2023

Abstract
The natural buckwheat flour exhibits poor processing behaviour due to its conservative structure and the lack of gluten protein, thereby limiting its use in the food industry. The replacement of chemical modification with sustainable, environmentally friendly steam treatment is, currently, technically feasible and promising for most chemical modification methods. The data showed that the steam-treated buckwheat flour degree of gelatinization increased to 99.3 g/100 g, and water absorption increased to 3.93 g/100 g. Also, particle size of the samples in the trial group was significantly larger compared to the control group. Scanning electron microscopy and infrared tests showed that not only did the steam treatment disrupt the granular structure of the buckwheat flour, but its proximity crystalline ordering structure Importantly, rheological behaviour tests showed that the steam-treated buckwheat gel exhibited a better viscoelasticity. Consequently, steam-treated pre-gelatinized buckwheat flour readily forms a tight network structure and provided important information for potential processing applications.

Published: April 2023

Abstract
In this study, polyvinylidene fluoride (PVDF) thick films with thickness ∼180 µm were synthesized by solution casting. X-ray diffraction study established the co-existence of both α and β-phases. Raman spectroscopy of the synthesized PVDF thick films corroborated the existence of α and β-phases in 0.71:1 ratio. Surface micrographs of PVDF thick films showed dense microstructure with grain size ∼10 µm. Additionally, the room temperature values of dielectric constant and dielectric loss at 100 kHz were measured to be ∼20 and 0.33, respectively. Furthermore, ferroelectric behavior of PVDF thick films was confirmed by the polarization versus electric field (P–E) hysteresis loop study. A leakage current density of 1.55 × 10−5 A cm−2 at an applied electric field of 500 kV cm−1 was obtained in PVDF thick films.
Thermodynamic analysis of the effect of rotation on gas adsorption

Published: April 2023

Abstract
This study examines the effect of a short term rotation on a system of constant volume. Adsorption of CO2 is performed on Activated Carbon (AC) at 281, 293 and 298 K with a special designed device that allows rotation. The adsorption isotherms were conducted up to 10 bar for both No Rotational (NoROT) and Rotational (ROT) cases. The ROT case refers to 60 s of rotation at 5000 rpm. The experimental results were fitted to Langmuir as well as to Dubinin–Astakhov (D–A) models with the latter presenting the best fit. A detailed thermodynamic analysis is performed in order to quantify the overall contribution of the rotation on gas adsorption compared to static case. For the ROT case, the maximum amount adsorbed (q
max) is by 12 % higher than the NoROT counterpart, while a decrease in chemical potential as surface loading is increased, indicates that the process after rotation is entropy driven. The outcome of this work suggests that rotation enables gas molecules to access previously inaccessible sites, thus gaining more vacancies due to better rearrangement of the adsorbed CO2 molecules.
Experimental observations of communication in blackout, topological waveguiding and Dirac zero-index property in plasma sheath
Authors: Li Jianfei , Wang Ying , Zhou Zhongxiang , Yao Jingfeng , Liu Jianlong , Lan Zhihao , Yuan Chengxun 
Published: April 2023

Abstract
The plasma sheath causes the spacecraft’s communication signal to attenuate dramatically during the re-entry period, which seriously threatens the astronauts. However, valid experimental protocols have not been obtained hitherto. To realize the propagation of electromagnetic waves in negative permittivity background of the plasma sheath, alumina columns are embedded in the plasma background to form plasma photonic crystals, which can support the coupling of evanescent waves between the alumina columns. We experimentally demonstrate the realization of communication in blackout scenario by achieving a complete passing band in the plasma cutoff region. For high frequency communications in the plasma sheath, electromagnetic wave propagation based on topological edge states is also experimentally demonstrated. Furthermore, we realize a triply-degenerate Dirac cone formed dynamically at the center of the Brillouin zone by modulating the electron density, where electromagnetic wave exhibits high transmittance and does not experience phase accumulation at the Dirac point. Our work thus not only provides an effective approach to overcome the communication blackout problem, but the design can also be served as a promising experimental platform to explore topological electromagnetic phenomena.
Tilting light’s polarization plane to spatially separate the ultrafast nonlinear response of chiral molecules
Authors: Rego Laura , Smirnova Olga , Ayuso David 
Published: April 2023

Abstract
Distinguishing between the left- and right-handed versions of a chiral molecule (enantiomers) is vital, but also inherently difficult. Traditional optical methods using elliptically/circularly polarized light rely on linear effects which arise beyond the electric-dipole approximation, posing major limitations for ultrafast spectroscopy. Here we show how to turn an ultrashort elliptical pulse into an efficient chiro-optical tool: by tilting its polarization plane towards its propagation direction. This forward tilt can be achieved by focusing the beam tightly, creating structured light which exhibits a nontrivial polarization pattern in space. Using state-of-the-art computational modelling, we show that our structured field realizes a near-field interferometer for efficient chiral recognition that separates the nonlinear optical response of left- and right-handed molecules in space. Our work provides a simple, yet highly efficient, way of spatially structuring the polarization of light to image molecular chirality, with extreme enantio-efficiency and on ultrafast time scales.

Abstract
This work demonstrates the employment of tungsten trioxide/polydimethylsiloxane nanocomposite saturable absorber (WO3/PDMS-SA) in realizing mode-locked conventional soliton (CS) and noise-like pulse (NLP) laser generation in net anomalous dispersion. The switching formation from CS regime of 970.0 fs pulse duration to NLP regime of 182.0 fs coherent spike with 65.3 ps pedestal was achieved by varying its pump power. The pulse laser exhibited good stability of 50.76 and 49.82 dB signal-to-noise ratio at 9.09 MHz fundamental repetition rate and trivial variation during stability test for CS and NLP regime, respectively. This work expresses the feasibility of WO3/PDMS-SA in attaining various types of mode-locked pulse phenomena using a fixed cavity configuration conceivably beneficial for compact dual-purpose laser systems.

Authors: Wnuczek Krystyna , Puszka Andrzej , Podkościelna Beata 
Published: April 2023

Abstract
The paper studies thermal characteristics of new polycarbonates obtained using the bisphenol A-free technology. Thermal tests of polycarbonates were carried out in a wide temperature range using the DSC (diffrential scanning calorimetry) and TG (thermogravimetry) analyses. The DSC data confirmed that all materials are homogeneous whereas the endothermic peaks are responsible for melting. Additionally, the analysis of the released gases was made by means of the infrared spectroscopic analysis. Our research proved that the new polycarbonates are relatively heat resistant. In the range of the thermal destruction of the studied materials there can be considered, two types of degradation reactions. The first step around 200 °C and the second one around 300 °C. Gel permeation chromatography were performed to determined molar masses of polymers. XRD analysis showed that the obtained polycarbonates showed a partially crystalline structure.

AbstractThe peptide hormone angiotensin II regulates blood pressure mainly through the type 1 angiotensin II receptor AT1R and its downstream signaling proteins Gq and β‐arrestin. AT1R blockers, clinically used as antihypertensive drugs, inhibit both signaling pathways, whereas AT1R β‐arrestin‐biased agonists have shown great potential for the treatment of acute heart failure. Here, we present a cryo‐electron microscopy (cryo‐EM) structure of the human AT1R in complex with a balanced agonist, Sar1‐AngII, and Gq protein at 2.9 Å resolution. This structure, together with extensive functional assays and computational modeling, reveals the molecular mechanisms for AT1R signaling modulation and suggests that a major hydrogen bond network (MHN) inside the receptor serves as a key regulator of AT1R signal transduction from the ligand‐binding pocket to both Gq and β‐arrestin pathways. Specifically, we found that the MHN mutations N1113.35A and N2947.45A induce biased signaling to Gq and β‐arrestin, respectively. These insights should facilitate AT1R structure‐based drug discovery for the treatment of cardiovascular diseases.

OBJECTIVES
Throughout the pandemic, children with COVID-19 have experienced hospitalization, ICU admission, invasive respiratory support, and death. Using a multisite, national dataset, we investigate risk factors associated with these outcomes in children with COVID-19.

METHODS
Our data source (Optum deidentified COVID-19 Electronic Health Record Dataset) included children aged 0 to 18 years testing positive for COVID-19 between January 1, 2020, and January 20, 2022. Using ordinal logistic regression, we identified factors associated with an ordinal outcome scale: nonhospitalization, hospitalization, or a severe composite outcome (ICU, intensive respiratory support, death). To contrast hospitalization for COVID-19 and incidental positivity on hospitalization, we secondarily identified patient factors associated with hospitalizations with a primary diagnosis of COVID-19.

RESULTS
In 165 437 children with COVID-19, 3087 (1.8%) were hospitalized without complication, 2954 (1.8%) experienced ICU admission and/or intensive respiratory support, and 31 (0.02%) died. We grouped patients by age: 0 to 4 years old (35 088), and 5 to 11 years old (75 574), 12 to 18 years old (54 775). Factors positively associated with worse outcomes were preexisting comorbidities and residency in the Southern United States. In 0- to 4-year-old children, there was a nonlinear association between age and worse outcomes, with worse outcomes in 0- to 2-year-old children. In 5- to 18-year-old patients, vaccination was protective. Findings were similar in our secondary analysis of hospitalizations with a primary diagnosis of COVID-19, though region effects were no longer observed.

CONCLUSIONS
Among children with COVID-19, preexisting comorbidities and residency in the Southern United States were positively associated with worse outcomes, whereas vaccination was negatively associated. Our study population was highly insured; future studies should evaluate underinsured populations to confirm generalizability.

Authors: Wu Chi-Fang , Highfield Linda , Swint John M. , Lairson David R. 
Published: April 2023

CONTEXT
Provider-based human papillomavirus (HPV) vaccine promotion interventions have been widely implemented; however, the effectiveness of these approaches is unclear.

OBJECTIVES
This systematic review assessed the effects and costs of provider-based interventions designed to increase HPV vaccination coverage. A meta-analysis was conducted to estimate pooled effect sizes of the interventions.

DATA SOURCES
We searched PubMed, Medline, Embase, and the Cochrane Library.

STUDY SELECTION
We identified articles on provider-based HPV vaccine promotion interventions published in English between 2007 and 2021.

DATA EXTRACTION
Information about the interventions’ effects and costs was extracted from the studies. A meta-analysis was performed to estimate the pooled intervention effects, including changes in the HPV vaccine initiation rate, HPV vaccine completion rate, and the percentage of patients receiving the next needed dose.

RESULTS
We identified 32 studies of provider-based interventions to improve the HPV vaccination rate. The reported intervention strategies included provider training, provider reminders, and provider assessment and feedback. In the meta-analysis, we found significant improvements in the HPV vaccine initiation rate (3.7%) and the percentage of patients receiving the next needed dose (9.4%).

LIMITATIONS
Because of the limited number of studies, we were unable to compare the same outcomes between different provider-based approaches. We found the high heterogeneity across studies. The random effects method was applied to adjust for study heterogeneity, the heterogeneity remined high for certain outcomes.

CONCLUSIONS
Provider-based interventions were effective in improving HPV vaccination rates. Sustainability and continuous implementation are the central factors that contributed to intervention success.

Published: April 2023

BACKGROUNDS
This study aimed to determine the best educational application of a respiratory function monitor and a video laryngoscope.

METHODS
This study was a randomized controlled simulation-based trial, including 167 medical students. Participants had to execute ventilation and intubation maneuvers on a newborn manikin. Participants were randomized into 3 groups. In group A (no-access), the feedback devices were not visible but recording. In group B (supervisor-access), the feedback devices were visible to the supervisor only. In group C (full-access), both the participant and the supervisor had visual access.

RESULTS
The two main outcome variables were the percentage of ventilations within the tidal volume target range (4–8mL/kg) and the number of intubation attempts. Group C achieved the highest percentage of ventilations within the tidal volume target range (full-access 63.6%, supervisor-access 51.0%, no-access 31.1%, P &lt; .001) and the lowest mask leakage (full-access 34.9%, supervisor-access 46.6%, no-access 61.6%; A to B: P &lt; .001, A to C: P &lt; .001, B to C: P = .003). Overall, group C achieved superior ventilation quality regarding primary and secondary outcome measures. The number of intubation attempts until success was lowest in the full-access group (full-access: 1.29, supervisor-access: 1.77, no-access: 2.43; A to B: P = .001, A to C: P &lt; .001, B to C: P = .015).

CONCLUSIONS
Our findings confirm that direct visual access to feedback devices for supervisor and trainees alike considerably benefits outcomes and can contribute to the future of clinical education.
