Abstract
Brazil has regions where the potential for wood supply is substantial and the lack of knowledge about forest species becomes a possible barrier to its acceptance, as is the case of the wood from the Caatinga biome. This research aims to identify the highlights attributes of wood from this biome in the perception of producers of small wooden objects as a premise for market studies. For this purpose, nine species of this biome were used as study objects for exploratory research with semistructured interviews and use of word cloud and similarity analyses with the IRAMUTEQ software. As a result, it was found that, in the perception of the producers, Caatinga biome species have peculiarities with the “color” aspect of the wood, which is the attribute considered important in adding value to products and, moreover, making it possible to group the woods according to their subjective peculiarities. It was found that a more effective participation of little-known species and an increase in demand due to greater acceptance in the market could enable the use in association with and/or as a replacement for traditional woods. In addition, the analysis of qualitative data with IRAMUTEQ is still incipient in the scientific forestry area; the present research contributes methodologically, demonstrating that its use increases the rigor of the investigation and the identification of prominent attributes of wood species, specifically those of the Caatinga studied, as alternatives for the market beyond firewood and charcoal.

Authors: King HE , Ricketts D , Roper T , Phadnis J 
Published: March 2022

Introduction Shoulder arthroplasty (SA) procedures are increasing in number worldwide. Medical complications (MC) following SA have not been widely documented in the literature. Knowledge of these complications is needed to obtain informed consent. Methods The aim of this review article was to summarise the literature regarding systemic complications and mortality after SA to aid the consenting process. Findings We found that the literature regarding MC after SA was variable in quality. The rate of MC was 12% and the rate of mortality was 0.01%. The most common MC were cardiovascular, genitourinary and respiratory. The patients most at risk were the elderly, females, fracture patients and those with HIV or hepatitis C. During inpatient stay, reverse arthroplasty and blood transfusion were associated with MC. We recommend that our data are used to obtain informed consent for SA. Conclusions To reduce risk, we encourage optimisation of patients prior to surgery with correction of anaemia, arranging necessary clinician reviews and appropriate postoperative nursing care.

BackgroundExercise in different health sectors is an important step in preparing programs for disaster risk management. The present study aimed to develop and validate a tool for evaluating disaster exercises during the design stage in the health sector.MethodsThis methodological study was conducted in two phases using an explanatory sequential mixed method approach. Semi-structured interviews with 25 disaster-related health professionals were conducted during the qualitative phase (item generation), and a systematic review was done to evaluate items pool of disaster exercises design stage tool. The quantitative phase (item reduction) assessed both face and content validity, as well as reliability using Cronbach’s alpha and intra-class correlation coefficient.ResultsAt the first stage four main categories and eleven subcategories were extracted from the data, the main categories including "coordination, command and guidance of exercise", "hardware and software requirements of exercise ", "organizational exercise resources", and "communication and exercise public information". The initial items pool included 164 items that were reduced to 50 after the assessment of validity (face and content). Cronbach’s alpha (0.89) and intra-class correlation coefficient (ICC = 0.72) tests indicated that the tool is also reliable.ConclusionThe research findings provide a new categorization perspective to understand the disaster exercises evaluation in the health sector. The existing 50-item tool can evaluate disaster exercises design stage in the health sector through collecting data with appropriate validity and reliability.

Introduction
Mental, neurological and substance use conditions lead to tremendous suffering, yet globally access to effective care is limited. In line with the 13th General Programme of Work (GPW 13), in 2019 the World Health Organization (WHO) launched the WHO Special Initiative for Mental Health: Universal Health Coverage for Mental Health to advance mental health policies, advocacy, and human rights and to scale up access to quality and affordable care for people living with mental health conditions. Six countries were selected as ‘early-adopter’ countries for the WHO Special Initiative for Mental Health in the initial phase. Our objective was to rapidly and comprehensively assess the strength of mental health systems in each country with the goal of informing national priority-setting at the outset of the Initiative.

Methods
We used a modified version of the Program for Improving Mental Health Care (PRIME) situational analysis tool. We used a participatory process to document national demographic and population health characteristics; environmental, sociopolitical, and health-related threats; the status of mental health policies and plans; the prevalence of mental disorders and treatment coverage; and the availability of resources for mental health.

Results
Each country had distinct needs, though several common themes emerged. Most were dealing with crises with serious implications for population mental health. None had sufficient mental health services to meet their needs. All aimed to decentralize and deinstitutionalize mental health services, to integrate mental health care into primary health care, and to devote more financial and human resources to mental health systems. All cited insufficient and inequitably distributed specialist human resources for mental health as a major impediment.

Conclusions
This rapid assessment facilitated priority-setting for mental health system strengthening by national stakeholders. Next steps include convening design workshops in each country and initiating monitoring and evaluation procedures.
Evaluating the population-level effects of overdose prevention sites and supervised consumption sites in British Columbia, Canada: Controlled interrupted time series
Authors: Panagiotoglou Dimitra 
Published: March 2022

Background
On 14 April 2016, British Columbia’s Provincial Medical Health Officer declared the overdose crisis a public health emergency, sanctioning the implementation of new overdose prevention sites (OPS) and supervised consumption sites (SCS) across the province.

Methods
We used the BC Centre for Disease Control’s Provincial Overdose Cohort of all overdose events between 1 January 2015 and 31 December 2017 to evaluate the population-level effects of OPSs and SCSs on acute health service use and mortality. We matched local health areas (LHA) that implemented any site with propensity score matched controls and conducted controlled interrupted time series analysis.

Results
During the study period, twenty-five OPSs and SCSs opened across fourteen of British Columbia’s 89 LHAs. Results from analysis of LHAs with matched controls (i.e. excluding Vancouver DTES) were mixed. Significant declines in reported overdose events, paramedic attendance, and emergency department visits were observed. However, there were no changes to trends in monthly hospitalization or mortality rates. Extensive sensitivity analyses found these results persisted.

Conclusions
We found OPSs and SCSs reduce opioid-related paramedic attendance and emergency department visit rates but no evidence that they reduce local hospitalization or mortality rates.

and 𝛽 is a positive constant.
For solving this problem approximately, a symmetric three-layer semi-discrete scheme with respect to the temporal variable is applied, in which the value of a nonlinear term is taken at the middle point.
This approach allows us to find numerical solutions per temporal steps by inverting the linear operators.
In other words, applying this scheme, a system of linear ordinary differential equations is obtained.
The local convergence of the scheme is proved.
The results of numerical computations using this scheme for different test problems are given for which the Legendre–Galerkin spectral approximation is applied with respect to the spatial variable.
Discrete probability model-based method for recognition of multicomponent combustible gas explosion hazard sources
Authors: Ye Wenhua , Feng Yang , Chen Yangming 
Published: March 2022

Abstract
Aiming at the problems of poor sensitivity and low accuracy of traditional combustible gas explosion hazard identification methods, the discrete probability model was introduced to design a multicomponent combustible gas explosion hazard identification method. Fem3 model is selected to analyze the diffusion mode of multicomponent combustible gas, and the calculation formula of diffusion velocity is obtained. The explosion limit of multicomponent combustible gas was observed by means of test, and the upper limit of explosion concentration of multicomponent combustible gas was obtained. According to the characteristics of explosion, a multicomponent combustible gas explosion hazard identification device is designed. The discrete probability model is used to identify the explosion hazard of multicomponent combustible gas. Experimental results show that the proposed method greatly improves the recognition sensitivity and accuracy, which fully shows that the proposed method has a better detection effect.

AbstractSilicon was recovered from solar cell Si scraps through 42.5 mol% SiO2–42.5 mol% CaO–15 mol% Al2O3slag refining. The motion behaviors of Si3N4and SiC were observedin situand real-time using a high-temperature laser confocal microscope, and the recovery of Si through slag refining was carried out at 1,500°C for 30 min. Results indicated that both SiC and Si3N4inclusions were concentrated in the slag, and this work provides a clear framework for recycling and reusing solar cell Si scraps.
Health as a Purpose or as a Right – The Principle of Proportionality and the Measures Against the Covid-19 Pandemic
Authors: Ducatti Lino Machado Gabriel 
Published: March 2022

Abstract
The Covid-19 pandemic has given cause for serious restrictions of fundamental liberty rights. In the legal doctrine of fundamental rights, the classical tool for the assessment of the material constitutionality of interferences with fundamental rights is the principle of proportionality. Indeed, the material determinant of the principle of proportionality is the intensity of the intervention in the fundamental right. One preliminary question, however, is often underestimated: the question as to the constitutional status of the interests protected or promoted by the intervening measures. After outlining the structure of the principle of proportionality, this article investigates the constitutional status that the interests protected by Covid-19 measures might have: is the protection of people’s health merely a legitimate purpose or a right? Finally, this article shows, with recourse to decisions of the German and Brazilian Constitutional Courts, the implications that different classifications have for the principle of proportionality.

Published: March 2022

Abstract
Heterocoagulation in alumina–silica suspension is studied using 2-dimensional discrete element method simulations. Controlling the structure and stability of the binary suspensions via selecting the appropriate size of precursors is crucial in ceramics processing. Alumina and silica particles with a broad range of sizes and size ratios are investigated. The size and the size ratio determine the degree of heterocoagulation and impact the suspension’s structure. Analyzing simulation results shows that when the sizes of silica and alumina particles are comparable, and the radii of particles are below 300 nm, a chain-like structure is formed. In suspensions with high size asymmetry, smaller silica particles surround larger alumina particles, and the degree of heterocoagulation is dependent on the composition of the suspension. The results show that suspension composition can also be used to tune the heterocoagulation structure.

Published: March 2022

Abstract
In this research, we analyze the effect of lightweight syntactical feature extraction techniques from the field of information retrieval for log abstraction in information security. To this end, we evaluate three feature extraction techniques and three clustering algorithms on four different security datasets for anomaly detection. Results demonstrate that these techniques have a role to play for log abstraction in the form of extracting syntactic features which improves the identification of anomalous minority classes, specifically in homogeneous security datasets.
Integration of GNSS observations with volunteered geographic information for improved navigation performance
Authors: Hassan Tarek , Fath-Allah Tamer , Elhabiby Mohamed , Awad Alaa ElDin , El-Tokhey Mohamed 
Published: March 2022

Abstract
Pedestrian and vehicular navigation relies mainly on Global Navigation Satellite System (GNSS). Even if different navigation systems are integrated, GNSS positioning remains the core of any navigation process as it is the only system capable of providing independent solutions. However, in harsh environments, especially urban ones, GNSS signals are confronted by many obstructions causing the satellite signals to reach the receivers through reflected paths. These No-Line of Sight (NLOS) signals can affect the positioning accuracy significantly. This contribution proposes a new algorithm to detect and exclude these NLOS signals using 3D building models constructed from Volunteered Geographic Information (VGI). OpenStreetMap (OSM) and Google Earth (GE) data are combined to build the 3D models incorporated with GNSS signals in the algorithm. Real field data are used for testing and validation of the presented algorithm and strategy. The accuracy improvement, after exclusion of the NLOS signals, is evaluated employing phase-smoothed code observations. The results show that applying the proposed algorithm can improve the horizontal positioning accuracy remarkably. This improvement reaches 10.72 m, and the Root Mean Square Error (RMSE) drops by 1.64 m (46 % improvement) throughout the epochs with detected NLOS satellites. In addition, the improvement is analyzed in the Along-Track (AT) and Cross-Track (CT) directions. It reaches 6.89 m in the AT direction with a drop of 1.076 m in the RMSE value, while it reaches 8.64 m with a drop of 1.239 m in the RMSE value in the CT direction.

Published: March 2022

Abstract

Objectives
To evaluate the association between low regional cerebral oxygen saturation (rScO2) and neurodevelopment in preterm infants classified as no brain injury (NBI).

Methods
We retrospectively reviewed data of rScO2 monitoring during the first 3 days of life of infants with a gestational age (GA)<28 weeks or birth weight (BW)<1,000 g, with and without brain injury (BI). BI was defined as intraventricular haemorrhage, cystic periventricular leukomalacia or cerebellar haemorrhage. Univariate and multivariate analyses were used to study the association of rScO2<55% for more than 10 h in the first 3 days of life (NIRS<55%>10H) and the 24 months neurodevelopment.

Results
Of the 185 patients who met the inclusion criteria, 31% were classified as BI infants and 69% NBI. BI compared to NBI infants had a significantly lower GA and a higher incidence of complications of prematurity. Mean rScO2 in the first 72 h of life was significantly lower in BI than NBI. NIRS<55%>10H in NBI patients was negatively associated with neurodevelopmental scores both at the univariate and multivariate analysis (p<0.05). NBI infants with NIRS<55%>10H were found to have lower systemic oxygenation than their counterparts with rScO2<55% for less than 10 h.

Conclusions
NIRS<55%>10H in NBI small preterm infants was found to be an independent predictor of neurodevelopment at 24 months and it was associated with low systemic saturation values.
Epidemic Analysis and Mathematical Modelling of H1N1 (A) with Vaccination
Authors: Jonnalagadda Jagan Mohan 
Published: March 2022

Abstract
This article investigates a proposed new mathematical model that considers the infected individuals using various rate coefficients such as transmission, progression, recovery, and vaccination. The fact that the dynamic analysis is completely determined by the basic reproduction number is established. More specifically, local and global stabilities of the disease-free equilibrium and the endemic equilibrium are proved under certain parameter conditions when the basic reproduction number is below or above unity. A realistic computer simulation is performed for better understanding of the variations in trends of different compartments after the outbreak of the disease.

The role of neuroimmune interactions in musculoskeletal pain
Authors: Schaible Hans-Georg , Ebersberger Andrea , Natura Gabriel , Vazquez Enrique 
Published: March 2022

Abstract
Interactions of the immune system and the nociceptive system play an important role in the generation and maintenance of pain in musculoskeletal diseases and in disease development. In inflamed tissue peripheral nociceptive neurons are rendered hyperexcitable by proinflammatory cytokines, antigen/antibody complexes and other immune mediators. Spinal nociceptive neurons are rendered hyperexcitable with the support of microglial cells, the immune cells of the central nervous system. The so-elicited sensitization of pain pathways has a strong impact on pain processing in the brain. On the other hand, immune processes are regulated by the nervous system. Sensory neurons, by releasing neuropeptides, and efferent neurons of the sympathetic nervous system support immune processes which promote disease development.
On explaining stable dialect features: A real- and apparent-time study on the variable (en) in Austrian base dialects
Authors: Vergeiner Philip C. , Wallner Dominik 
Published: March 2022

AbstractReferring to the so-called “actuation problem”, stability and change are two equally important problems in every theory of language change. However, apart from some exceptions, up to now studies predominantly focused on change, while stable linguistic features have been rarely considered. To address this desideratum and investigate factors that account for stability, the present article combines a real- and apparent-time analysis of the variable (en) in the Austrian base dialects by investigating data from 163 base dialect speakers from 40 locations across the country. The variable (en) occurs as a word-final ending in infinitive as well as in nominal forms, and – with respect to the preceding phonetic environment – shows a high degree of variation within and across all Austrian dialect areas. Although such a high degree of variation is considered a prerequisite for change, the analyses reveal a remarkable amount of stability for several variants of (en) in Austria. As will be argued, this fact can be attributed to both extra- and intralinguistic factors such as the variant’s areal distribution, its frequency, and morphological constraints.
