Published: March 2023

Welding defects in a construction if repairs are not immediately carried out, then in the weld defect area can cause cracks that are aggravated by wider cracking and corrosion so that it can cause brittle fractures to the detriment. The problem with brittle fracture is a big problem in steel that has been welded, especially in welded joints, this brittle fracture becomes more important due to the factors of voltage concentration, inappropriate structure and defects in the weld, the purpose of this study: to find out how to use suitable electrodes for ST 37 material in the welding process, whose cooling process directly uses Oil and water (Direct Colling Process), and to obtain optimal welding results after going through the results of welding defect examination using the Penetrant Test method, and the Maghnetic Particle Test. From the results of the examination research conducted by the Welding Inspection team of PT. Superintending Company of Indonesia (SUCOFINDO) to 15 ST 37 specimens that have undergone welding does not show any welding defects, in the sense that they are still within the acceptable limit criteria (Acceptance Standard Ansi B 31.3), from the results of tensile testing On the use of different electrodes in the welding process of ST 37 material, shows that the ST 37 material whose welding process uses electrode E7016 welded results and tensile strength is better than the ST 37 material which in the welding process uses electrodeS E 7018 with the cooling process using Oil and water

Published: March 2023

Fabrication technology has also penetrated the oil and gas industry, such as in the case of joining materials, one of the applications being made is the connection of pipes by welding. In the welding process, the heat distribution is uneven and the cooling rate is fast, resulting in residual stresses. This is indicated by changes in the microstructure in the weld area and the Heat Affecting Zone (HAZ), causing the material to become hard but brittle (brittle). This can cause structural failure in the connection area. This study investigates the residual stresses in pipe welding ASTM A 106 Grade B using the finite element method with ANSYS R17.2 software. The simulation is divided into 2 steps, namely thermal and structural analysis. The variation used in this simulation is the electric current as the welding heat input. The electric current is 110 A with an effective heat input of 2337.5 Watts with a maximum residual voltage of 399.59 MPa, 2762.5 Watts with a current of 130 A of 420.01 MPa, 3400 Watts with a current of 160 A of 454.06 MPa. The simulation shows that an increase in electric current in the range of 110 to 160 A can imply an increase in residual voltage. A welding heat input is obtained with the minimum residual voltage value, namely at a current of 110 A with an effective heat input of 2337.5 watts.

Transportation of oil and gas through oil refinery pipelines is faced with problems, including corrosion problems. Corrosion is a natural phenomenon that occurs in metal materials, where corrosion is a process of material damage due to chemical or electrochemical reactions with its environment. The purpose of this study is the results of the analysis of HydroTest pressure variations on the Welding Joints of Carbon Steel Pipes (carbon steel) A106 Gr.B. In the study did not discuss the occurrence of corrosion and other tests, while the welding process in detail was shown in WPS. This experimental research method uses the Welding Repair Method on welded joints according to the ASME IX, ASME B31.3 standard. The research material is A106 GR carbon steel pipe. B is in the form of a U Tube Seal Deck that has undergone corrosion and damage, where later the fabrication process (pipe repair) especially welding (using SMAW and GTAW) has been determined in PQR and WPS (WPS / CS / EM / ASME / WPxxx). The focus of this research is on stage 9 (hydro testing stage) of the Welding Repair method. Free variables in pressures of 240 Psi, 435 Psi, 690 Psi, and 910 Psi, which have been planned based on the thickness and length of the Pipe joint. Variable fixed temperature test Hydrotest 28OC, holding time holding time (pressurizing) 10 minutes and holding time peak 60 minutes before (depressurizing). The results were obtained that the pressure change was divided into two stages, pressurizing with the highest pressure of 915 Psi is the 4th pressure variation this was obtained from the test observation that there were no leaks in the welded joints and pipe materials in accordance with the acceptance criteria. While the second stage is (depressurizing) with a decrease in pressure or called realese, where successively realese 100%, 75%, 50%, 25%, and 0% at pressures of 915 Psi, 690 Psi, 435 Psi, 240 Psi, 0 Psi with the results of no leakage and observation test results in accordance with the acceptance criteria. So it can be concluded that the welded joints of carbon steel pipes tested using hydrotest, no deformation occurs, there is no change in shape and there are no leaks in the welded joint layer of A106 Gr.B carbon steel pipe

The Concept of Sustainable Development: The Evolution of Theoretical Approaches and Modern Vision
Authors:   Institute of Agrarian Problems RAS — Subdivision of the Saratov Federal Scientific Center of the Russian Academy of Sciences, Kadomtseva M. Ye.
Published: March 2023

Since the end of the 19th century, the concept of sustainable development has evolved from its origi­nal focus on the environmental dimension of economic growth to its current understanding summarized in the UN’s 17 Sustainable Development Goals. The new challenges of our time, such as the pandemic, global climate change, increased social inequality, and geopolitical tensions, have necessitated a search for solutions that go beyond inertial economic doctrines. This article aims to present a holistic view of the transformation in scientific approaches to the problems of sustainable economic, social, and environmental development at different stages. It also aims to substantiate the main provisions of the concept of sustainable development in the context of current global trends. The article, therefore, contains a review of Russian and international literature on sustainable development showing the key research trends in this field. Applying a combination of historical-statistical and theoretical analysis methods, the study describes the circumstances which led to a change in the views on the “economy-nature-society” triad. As a result, insights are offered into the most likely directions for further transformations of the concept of sustainable development and associated global trends.

C1 atlas cannot indicate brain metabolism in the Little Foot hominin
Authors: Meyer Marc R.
Published: March 2023

In their recent article, “The atlas of StW 573 and the late emergence of human-like head mobility and brain metabolism” Beaudet and colleagues (Scientific Reports, March 2020) contend that StW 573 had lower metabolic costs for cerebral tissues and that blood perfusion of these tissues increased recently over the course of hominin evolution. This conclusion is in large part based on the assumption of a correlation between the size of the fossil vertebra’s transverse foramen and arterial canal diameters, and by extension, they use the foramen’s cross-sectional area in conjunction with the size of the cranium’s carotid canal to reconstruct blood flow volume to the brain as a proxy of the brain’s metabolic demands. As I show here, these assumptions are unsupported because the C1 cervical vertebra cannot help indicate hemodynamics or investment in brain metabolism.

Understanding the potential for downstream harms from data-intensive technologies requires strong collaboration across disciplines and with the public. Having shared vocabularies of concerns reduces the communication barriers inherent in this work. The Data Hazards project (datahazards.com) contains an open-source, controlled vocabulary of 11 hazards associated with data science work, presented as ‘labels’. Each label has (i) an icon, (ii) a description, (iii) examples, and, crucially, (iv) suggested safety precautions. A reflective workshop format and resources have also been developed. These have been created over three years with feedback from interdisciplinary contributors, and their use evaluated by workshop participants (N=47). They labels include concerns often out-of-scope for ethics committees like environmental impact. The resources can be used as a structure for interdisciplinary harms discovery work, for communicating hazards, collecting public input or in educational settings. Future versions of the project will develop through feedback from open-source contributions, methodological research and outreach.

Internet usage is a salient developmental factor in adolescents’ lives. Although relevant correlates of internet use have been documented earlier, there is a lack of information on lower socioeconomic status groups. This is important, as these adolescents have increased risk for negative online experiences. The current survey aimed to explore internet use and parental involvement amongst adolescents from areas of socio-economic disadvantage in 30 urban schools across five European countries. A total of 2,594 students participated, of whom 90% were 14-16 years. Virtually all adolescents of socioeconomic disadvantage had internet access, with 88.5% reporting spending more than two hours per day online, often on apps such as Instagram, Snapchat, and YouTube. Almost one-third of adolescents did not talk with their parents about their internet use and almost two-thirds indicated that their parents were only a little or not interested in their internet use. A consistent finding across countries was that girls more often talked with their parents about their internet use and more often reported that their parents were interested in their internet use than boys. The results suggest that parents have an important task in explicitly showing interest in their adolescents’ internet use, with special attention needed for boys.
Emotions under control? Better cognitive control predicts reduced negative emotionality but increased negative emotional reactivity within individuals
Authors: Rónai Levente , Hann Flóra , Keri Szabolcs , Ettinger Ulrich , Polner Bertalan
Published: March 2023

Associations between impaired cognitive control and maladaptive emotion regulation have been extensively studied between individuals. However, it remains unclear if this relationship holds within individuals. In this study, we tested the assumption that momentary within-person fluctuation in cognitive control (working memory updating and response inhibition) is associated with emotional reactivity in everyday life. We conducted an experience sampling study (eight two-hourly prompts daily) where participants repeatedly performed short 2-back and Go/no-go tasks in daily life. We assessed negative and positive affective states, and unpleasantness of a recent event to capture emotional reactivity. We analyzed two overlapping samples: a Go/no-go and a 2-back dataset (N = 161/158). Our results showed that better momentary working memory updating was associated with decreased negative affect if the recent event was on average unpleasant for the given individual. However, better-than-average working memory updating in interaction with higher event-unpleasantness predicted higher negative affect levels (i.e., higher negative emotional reactivity). These findings may challenge the account of better cognitive control being universally related to adaptive emotion regulation. Although it is unlikely that emotional reactivity boosts working memory, future studies should establish the direction of causality.

Published: March 2023

Background:

A multi-country outbreak of monkeypox virus (MPXV) infections was identified by the World Health Organization in May 2022. The western Canadian province of Alberta identified its first case of MPXV in a returning traveller on June 2, 2022. We undertook a retrospective testing exercise to evaluate whether MPXV may have been circulating in the province earlier.

Methods:

Skin (genital and non-genital) and mucosal lesion swabs submitted for herpes simplex virus (HSV)/varicella zoster virus (VZV)/syphilis testing from male patients attending sexually-transmitted infection clinics across the province of Alberta from January 28 to May 30, 2022 were retrieved from storage. The population tested was selected based on the epidemiology of the current 2022 multi-country MPXV outbreak. Samples underwent viral nucleic acid extraction and testing for the presence of Orthopoxvirus DNA using a commercial real-time polymerase chain reaction (PCR) kit.

Results:

A total of 392 samples (representing 341 unique individuals of median age 31 years) were retrieved. Of them, 349 (89.0%) samples were submitted for HSV/VZV/syphilis testing, 13 (3.3%) for HSV/VZV only, and 30 (7.7%) for syphilis PCR only. None of the 392 samples tested were found to be positive for Orthopoxvirus DNA.

Conclusions:

The results of this study indicate that circulation of MPXV in a higher-risk population in Alberta, prior to the first case, was less likely. We recommend that other provinces/territories review their local epidemiology, context and resources prior to conducting similar studies.

Published: March 2023

One of the problems of fallow land management in the arid conditions of southern Ukraine is the lack of technical means that would ensure the availability of moisture in the soil at the time of winter crops sowing. The article presents the results of the operational and technological evaluation of the machine-tractor unit consisting of a universal tillage tractor of traction class 1.4 and a new harrowing tool. Its peculiarity is the use of flat-cutting working bodies that loosen the upper (5...6 cm) layer of soil without significant removal of its moist part to the daytime surface. This unit was compared with a basic unit of the same purpose. It included a general-purpose tractor of traction class 3 and a cultivator of the KPS-8 type. Experimental studies have established that the use of a new machine-tractor unit for tillage in conditions of soil moisture deficiency can increase productivity by at least 8% and almost halve specific fuel consumption. The probability of maintaining the tolerance of fluctuations in the depth of tillage of the fallow field at the level of ±1 cm by the new harrowing unit is 78%.

Evaluating the performance of the RANS turbulence models for simulating wave propagation over a submerged breakwater using openfoam
Authors: Linh Luong Cao , Tri Mai Cao
Published: March 2023

The present work is to evaluate the performance of the RANS turbulence models for simulating regular wavepropagation over a submerged breakwater using the open-source Computational Fluid Dynamics (CFD) software OpenFOAM. The present numerical results of four turbulence models (k-ε model, k-ω  SST model, buoyancy-modified k-ω SST model, and stabilized k-ω SST model) are compared with published experimental data for free surface elevations and velocities at gauges. Moreover, the results of the turbulent kinetic energy (TKE) are compared and assessed between the turbulence models. Results show that the buoyancy-modified k-ω SST model and the stabilized k-ω SST model predictions agree very well with the experimental data, although the turbulence kinetic energy is still significant differences between the two models. Therefore, these two models should be used in the future for simulating the interaction between waves and submerged breakwaters.

Published: March 2023

Background:

Sarcopenia is characterized by a progressive loss of muscle mass, strength, and function resulting in adverse health outcomes. Current assessment strategies are bothersome and means to simplify the diagnosis are an unmet medical need in Parkinson’s disease (PD).

Objective:

To evaluate temporal muscle thickness (TMT) obtained on routine cranial MRI as a surrogate marker of sarcopenia in PD patients.

Methods:

We correlated TMT from axial non-contrast-enhanced T1-weighted sequences of MRI close (±12 months) to an outpatient visit including sarcopenia (EWGSOP1, EWGSOP2, SARC-F), frailty (Fried’s criteria, clinical frailty scale), and disease characteristics of Parkinson’s patients (Hoehn and Yahr-scale, Movement Disorder Society-Unified Parkinson’s Disease Rating Scale, quality of life with the Parkinson’s Disease Questionnaire-8) assessments.

Results:

Cranial MRI was available in 32 patients with a mean age of 73.56±5.14 years, mean disease duration of 11.46±5.66 years, and median Hoehn and Yahr stage of 2.5. The mean TMT was 7.49±2.76 (7.15) mm. Mean TMT was significantly associated with sarcopenia (EWGSOP2, p = 0.018; EWGSOP1, p = 0.023) and frailty status (physical phenotype; p = 0.045). Moreover, there were significant moderate to strong correlations between TMT measurement and appendicular skeletal muscle mass index ( r: 0.437, p = 0.012), as well as handgrip strength ( r: 0.561, p < 0.001).

Conclusion:

Reduced TMT seems to be a promising surrogate marker for sarcopenia (EWGSOP2) and muscle strength in this pilot study in PD patients.

Published: March 2023

BACKGROUND: Anxiety is a prominent disabling non-motor neuropsychiatric complication of Parkinson’s disease (PD). Pharmacological treatments for PD and anxiety have drug interactions and negative side effects. Therefore, non-pharmacological interventions such as exercise has been proposed to reduce anxiety in people with PD (PwP). OBJECTIVE: This systematic review aimed to explore the relationship between physical exercise and anxiety in PwP. METHOD: Four databases (PubMed, Embase, Scopus, Ebscohost) were searched without date restrictions. English randomized control trials (RCT) including adults with PD, exposed to physical exercise interventions with anxiety as an outcome variable, were included. Quality was assessed by means of an adapted 9-point PEDro scale. RESULTS: Five of the identified 5547 studies met the inclusion criteria. Sample size ranged between 11–152 participants, totaling 328 participants with majority being male. PD stage ranged from early to moderate, with disease duration ranged between 2.9 and 8.0 years. All studies measured anxiety at baseline and post-intervention. On average studies scored 7/9 (76%) on the PEDro scale. CONCLUSION: There is insufficient evidence to support or refute the effect of exercise on anxiety in PwP due to noted limitations of included studies. There is an urgent need for high-quality RCTs on physical exercise and anxiety in PwP.

METHODS: This was a retrospective study in which all subjects included were seen between 2004 and 2013 and were deemed appropriate for BoNT-A injections. A total of 291 patients were reviewed for inclusion in the study, and 134 patients met the inclusion criteria. Each child was injected with 15–30 units of BoNT-A into each of the following muscles: ipsilateral sternocleidomastoid, upper trapezius, and scalene muscles. The key outcome and variable measurements analyzed included age at time of diagnosis, age at time of initiation of physical therapy, age at time of injection, total number of injection series utilized, muscles injected, and degrees of active and passive cervical rotation and lateral flexion pre- and post-injection. A successful outcome was documented if a child could achieve 45° of active lateral flexion and 80° of active cervical rotation post-injection. Secondary variables including sex, age at time of injection, number of injection series utilized, surgery required, adverse effects of botulinum toxin, presence of plagiocephaly, side of torticollis, orthosis used, presence of hip dysplasia, skeletal anomalies, complications during pregnancy or birth, and any other pertinent information regarding the delivery were also measured. RESULTS: Based on this criteria, 82 children (61%) had successful outcomes. However, only four of the 134 patients required surgical correction. CONCLUSION: BoNT-A may be an effective and safe method for treatment in refractory cases of congenital muscular torticollis.
The Uncertainty of Fairness: a Game Theory Analysis for a Debt Mutualization Scheme in the Euro Area
Authors: D'Andrea Sara , Vassalli Federica
Published: March 2023

This paper aims to briefly present the fairness approach in game theory and its potential application. Fairness means that players consider not only personal payoffs but also others' payoffs and beliefs regarding their actions. In this context, we distinguish two approaches, one based on the material payoff and the other on beliefs. We adopt the fairness approach in proposing three games for studying the strategic interaction between a hypothetical country and the European Union in proposing a debt mutualization scheme. We find that the optimal debt quota to share with the European Union is 50%; concerning the moral hazard problem, commitment to structural reforms for countries with high public debt leads to the best equilibrium, that can be preserved following an incentive strategy.

Authors: Sandal Abdulsamet
Published: March 2023

Objective: This study aimed to investigate hepatic and renal functions in patients who received calcium disodium edetate (CaNa2EDTA) chelation treatment for chronic occupational lead intoxication.
Material and Methods: This single-center retrospective descriptive research was conducted in a secondary-level health facility. The study included patients treated with CaNa2EDTA chelation for chronic occupational lead intoxication between September 15, 2020, and May 31, 2021. Demographic and occupational characteristics, as well as and laboratory parameters obtained before and after the chelation therapy were evaluated.
Results: All 75 patients were male, and 73.3% had an occupation in metal scrap recycling. Renal parameters were within normal range before and after the chelation. However, mild elevations were observed in liver parameters. After the adjustment for demographic and occupational variables, the odds of having an elevated liver parameter and an elevated alanine transaminase (ALT) result after the chelation therapy were 9.3 (95%CI 2.6–33.2, p<0.001) and 11.4 (95%CI 2.4–53.2, p<0.001) for patients with pre-chelation elevated any liver parameter and pre-chelation elevated ALT result, respectively.
Conclusion: The current study documented mild elevations of the liver parameters in patients with chronic occupational lead poisoning after CaNa2EDTA chelation therapy, particularly those with elevated basal liver parameters, although their renal parameters stayed within reference ranges. The results serve as an example of the safe application of CaNa2EDTA chelation for chronic occupational lead poisoning, by monitoring kidney and liver parameters in a secondary-level health facility. Future prospective studies with structured treatment protocols may investigate the risk and determinants of hepatic and renal adverse effects.

Authors: Filho Paulo Cesar Gonçalves de Azevedo , Santos Jomel Francisco dos
Published: March 2023

A brucelose é uma infecção causada por bactérias do gênero Brucella e tem distribuição cosmopolita. Acomete mamíferos, podendo causar abortos e infertilidade em algumas espécies além de sérios prejuízos a produção animal, assim como para conservação de algumas espécies. É uma importante zoonose que pode acometer os seres humanos por meio do consumo de leite e derivados sem tratamento térmico adequado, ou ser transmitida também pelo contato de materiais contaminados como restos placentários ou abortos. Vale salientar a importância como zoonose ocupacional que pode acometer principalmente Médicos Veterinários, trabalhadores rurais, ordenhadores e magarefes, principalmente pelo contato com materiais contaminados e o manuseio incorreto da vacina viva liofilizada (B19).

The latitudinal distribution patterns of alpha, beta and gamma diversity of reptiles, amphibians and herpetofauna were analyzed using individual binary models of potential distribution for 301 species predicted by ecological modelling for a grid of 9,932 quadrants of ~25 km2 each. We arranged quadrants in 312 latitudinal bands in which alpha, beta and gamma values were determined. Latitudinal trends of all scales of diversity were similar in all groups. Alpha and gamma responded inversely to latitude whereas beta showed a high latitudinal fluctuation due to the high number of endemic species. Alpha and gamma showed a strong correlation in all groups. Beta diversity is an important component of the herpetofauna distribution patterns as a continuous source of species diversity throughout the region.
Factors influencing the breeding density of Bearded Vultures, Egyptian Vultures and Eurasian Griffon Vultures in Catalonia (NE Spain): management implications

Using multivariate analyses we examined differences in breeding density of the Bearded Vulture Gypaetus barbatus, the Eurasian Griffon Vulture Gyps fulvus and the Egyptian Vulture Neophron percnopterus in NE Spain (Catalonia) in relation to trophic, orographic-landscape and anthropic variables. Sampling units used were regional divisions (comarques). High density of Bearded Vulture was principally linked to areas with scant vegetation and low human population density. In contrast, high densities of both the Egyptian and Eurasian Griffon Vultures were associated with availability of trophic resources (sheep and goats). Positive effects were detected in relation to low density of inhabitants (Egyptian Vulture) and altitudes between 1,000-2,000 m and landscape with low tree cover (Eurasian Griffon Vulture). The Bearded Vulture seemed to be the most selective species in relation to environmental characteristics while the Eurasian Griffon and the Egyptian Vultures displayed a higher degree of ecological plasticity. Future conservation actions should bear these results in mind in order to optimise management. Food resources from extensive livestock farming, in particular, seem fundamental for the conservation of scavenger species. Preference monitoring and conservation efforts are needed in the regions with highest vulture densities (Alta Ribagorça, Pallars Jussà and Alt Urgell), while regions with low vulture populations should be managed in order to favour the geographical expansion and recolonisation of zones currently not occupied by these species. Conservation priorities should be based on favouring extensive livestock practices, and as an alternative to muladares (traditional animal carcass disposal sites) farmers should be encouraged to leave animal carcasses in the field, while ensuring compliance with health regulations.
