Published: August 2023

In the machining industry, reducing energy consumption at a maximal material removal rate (MRR) has long been a priority. Using the response surface method, a predictive model has been proposed for the minimal power consumption in side-milling machining. Using response surface method (RSM), the effect of cutting parameters (feed rate, spindle speed, and radial depth of cut) on power consumption was investigated. The results revealed thatfeed rateis the most inﬂuential parameter for power consumption. The higher feed rate, the shorter cycle time thus reduce the power consumption. Based on the optimization model, minimum power consumption of 82.38 kW can be achieved at feed rate = 6,000 mm/in, radial depth of cut of 0.3 mm and spindle speed 12,000 rpm.

Background: The present study was conducted to study the stability and diversity of twenty elite breeding lines of vegetable cowpea developed at ICAR-Indian Institute of Vegetable Research, Varanasi through AMMI analysis and cluster analysis respectively. Methods: All the 20 elite lines were laid out in randomized block design with three replications during three years of sowing viz., Kharif-2018, Kharif- 2019 and Kharif-2021. Each year was considered as onelocation and the dependant variable pod yield per plant was subjected to AMMI analysis for GE interaction study. The mean of all the yield and yield attributes was subjected to cluster analysis for genetic divergence study. Result: AMMI ANOVA showed significant variation for environments (E), genotypes (G) and G×E interactions. The graphical representation of principal component 1 (PC1) vs yield (Y) showed that the genotypes 12,15,11,13,18 were most stable andthe PC1 vs PC2 graph showed that the genotypes 12,11,13,18 were most stable as they were positioned towards the origin. The cluster analysis grouped all the twenty genotypes into four clusters with two genotypes (7,20) in first cluster, five genotypes (17,14,16,8,19) in second cluster, eight genotypes (9,6,1,13,11,12,2,15) in third cluster and five genotypes (5,3,18,4,10) in fourth cluster.
Gestión de Residuos en proyectos de construcción de viviendas en Costa Rica: teoría versus práctica
Authors: Cruz-Zuñiga Nidia 
Published: August 2023

El presente articulo sintetiza los resultados de varios proyectos de investigación que se han realizado en la Escuela de Ingeniería Civil, bajo la tutoría de la autora, y enmarcados en la línea de investigación de gestión integral de residuos en la construcción. El objetivo de la investigación ha sido generar información respecto a la tasa de generación de residuos en proyectos de construcción, al momento solamente para proyectos de vivienda, y estudiar su composición, con el fin de brindar pautas a las autoridades nacionales para una posible regulación del sector construcción en materia de residuos. Una de las principales hipótesis que se han estudiado es que existe una diferencia en la tasa de generación de residuos por metro cuadrado de construcción según la tipología constructiva que se maneje en el proyecto. La metodología seguida para estas investigaciones ha consistido en estudiar proyectos constructivos de diversa índole durante su fase de obra gris, y cuantificar en sitio todos los residuos que se van produciendo, llevando un control por peso y por avance de obra. Al mismo tiempo se han realizado caracterizaciones por tipo de residuo en todos los casos, con el fin de evidenciar que tipo de material de construcción genera mayor cantidad de residuo, por peso y por volumen. Adicionalmente, se ha estudiado los porcentajes de desperdicio, llevando un comparativo entre la cantidad de materiales que ingresan a cada proyecto y los residuos que se reflejan en campo, lo que se comparó luego con los porcentajes de desperdicio que indica la teoría para estimar los presupuestos. Entre las principales conclusiones a las que ha llegado la investigación al momento están el que los desperdicios suelen ser mayores en la práctica de lo que indica la teoría, pero que existen otras variables implicadas en la generación de residuos que hacen que proyectos de una misma tipología y hasta muy similares entre si tengan tasas de generación relativamente diferentes. También se ha podido observar cómo los proyectos construidos con sistemas modulares no precisamente tienen tasas de generación de residuos menores, como se indica en la teoría. Adicionalmente, si se ha comprobado que los proyectos constructivos que tienen elementos más complejos en diseño suelen generar tasas de residuos mayores, lo que parece estar relacionado a diseños arquitectónicos más elaborados.

Abstract
—Dataset on the Middle Devonian volcanic-carbonate–terrigenous sediments of Salair and the Kuznetsk trough, submerged northward under the Mesozoic–Cenozoic West Siberian geosyneclise (WSG) cover, have been presented. Mainly deep water sediments composed of thin- and fine-grained clastic material (with predominance of tephroids) and thin-, fine-clastic biodetrital limestones with slope slide breccia, as well as turbidites and peculiar “conglomerate-like” limestones (paleoseismites) were found. Sedimentary and geodynamic environments have been reconstructed for the Middle Devonian strata. Predominantly andesitic composition of pyroclastic ashes with fewer values of felsic and basic volcanic components have been determined. The structures related to the continental margin environments of the Siberian continent, the continental slope and its basement have been found. According to sedimentary and geochemical data, the paleogeodynamic environment within the studied region was relatively stable and generally corresponded to the island arc conditions. The paleoclimate of the source area changed from semi-humid in the late Emsian–early Eifelian (Malaya Salairka age) to aridic in the middle Givetian (Kerlegesh age). Basin sediments formed in the deep water oxic environments with good water aeration, excepting euxinic environments found in the lowermost part of studied succession.

Abstract
Background :The effect of α2 adrenergic receptor agonist-dexmedetomidine on evoked potentials in cervical spinal cord remains unclear at the current stage. Therefore,this research investigates the effect of dexmedetomidine on sensory evoked potential during cervical spine surgery under total intravenous anesthesia, so as to provide reference for clinical practice.
Methods:A total of 45 patients undergoing cervical spine surgery at the teaching hospital were randomly divided into group D (Dexmedetomidine group,n=23) and group C (Control group,n=22). Both groups were anesthetized with propofol and remifentanil. Group D was infused with dexmedetomidine starting at 1ug/kg for 10 minutes before induction, and then maintained at 0.4ug/kg/h during the operation. Group C was injected with the same dose of saline. Evoked responses were evaluated under seven conditions: awaking (T0), at the end of the loading dose infusion(T1), after induction of anesthesia (T2), after intubation (T3), positioning (T4), spinal canal decompression (T5), and interbody fusion cage insertion (T6).The amplitude (N13-P15, N45-P37) and latency (N13, P15, N45, P37) of SEP, heart rate (HR), mean arterial pressure (MAP), body temperature (T), and bispectral index (BIS) were recorded at these seven time points. The pre-and post-operative red blood cell specific volume (HCT) counts, as well as the intraoperative dosage of propofol and remifentanil were recorded in both groups.
Results:A total of 40 patients completed the study. 1. Compared with T0, the N13-P15 amplitude decreased at T1 and T6 in group D （P＜0.05）, and significantly decreased at T6 in group C（P＜0.01）; The amplitude of N45-P37 decreased at T1, T5, and T6 in group D(P＜0.05) , and significantly decreased at T5 and T6 in group C（P＜0.01）.Compared with group D, the N45-P37 amplitude significantly decreased at T4 in group C （P＜0.05）.2. Compared with T0, the N13, P15, N45, and P37 latency were not statistically significant in both groups (P>0.05). 3. There was no statistical difference in MAP, HR, T, and BIS between the two groups (P>0.05) .
Conclusion:Dexmedetomidine has no effect on the amplitude and latency of SEP in patients undergoing cervical spine surgery. More importantly, dexmedetomidine may have a protective effect on nerves during the positioning process.

Abstract

Previous studies have rarely investigated the role of non-vitamin K oral anticoagulants (NOAC) and warfarin in the secondary prevention of ischemic stroke patients with nonvalvular atrial fibrillation (NVAF). In this study, we compared the effectiveness and safety of NOAC and warfarin for secondary prevention in Korean ischemic stroke patients with NVAF. Based on the Korean National Health Insurance Service Database, this study included 21,064 oral anticoagulants-naïve acute ischemic stroke patients with NVAF between July 2015 and June 2019. The main study outcomes included ischemic stroke, systemic embolism, major bleeding, and death. During the observational periods, NOAC users had a significantly decreased risk of ischemic stroke + systemic embolism (adjusted hazard ratio [aHR], 0.86; 95% confidence interval [CI], 0.78–0.95), ischemic stroke (aHR, 0.89; 95% CI, 0.81–0.99), major bleeding (aHR, 0.78; 95% CI, 0.68–0.89), and all-cause death (aHR, 0.87; 95% CI, 0.81–0.93). Standard-dose NOAC users had a lower risk of ischemic stroke, systemic embolism, and major bleeding events than warfarin users. In contrast, low-dose NOAC users did not differ in risk from warfarin users for all outcomes. In conclusion, NOACs were associated with a lower risk of secondary thromboembolic events and bleeding complications in Korean ischemic stroke patients with NVAF than warfarin.
Associations Between Nature Exposure, Screen Use, and Parent-Child Relations: A Scoping Review
Authors: Torjinski Marina , Cliff Dylan , Horwood Sharon 
Published: August 2023

Abstract

Background Recent research suggests that children spend increasing amounts of time engaging in screen-based activities and less time outdoors in natural environments. There is a growing body of theory-driven literature evidencing that child screen use and exposure to nature are associated with wellbeing outcomes in contrasting ways. However, few studies have explored their combinative effects and the relational family context has been largely overlooked.
Objective This scoping review explored associations between early-late childhood nature exposure, screen use, and parent-child relations in order to identify research gaps and inform future research direction.
Methods This review was guided by Arksey and O’Malley’s five-stage methodological framework and other relevant guidelines for scoping reviews. A search of five electronic databases (PsycINFO, MEDLINE complete, ERIC, EMBASE and Cochrane library) was conducted along with additional hand-searches from inception to 9/06/2023. Peer-reviewed articles published in English between 2012-2023 were included.
Results A total of 284 articles were screened by title and abstract and full text review of 79 articles was conducted. Following additional searches (hand-search and reference lists), a total of 16 eligible articles were identified. The synthesis revealed that the relevant body of research is novel, heterogenous, and fragmented. There are various pathways through which children’s screen use and engagement with nature interact within the family context, however research exploring their synchronous and bidirectional effects on relational family processes is limited.
Conclusion Findings emphasize the importance of investigating children’s screen use and engagement with nature from a relational paradigm. Future studies should explore the mechanisms underpinning the reciprocal influences of nature and screen use on dyadic family processes and relational outcomes across early-late childhood.

Direct correlation between surface integrity and fatigue limit of surface cold worked chromium-nickel austenitic stainless steels
Authors: Maximov Jordan , Duncheva Galya , Anchev Angel , Dunchev Vladimir 
Published: August 2023

Abstract
Direct correlations were established between basic surface integrity (SI) characteristics (roughness, microhardness, residual stresses) obtained as a result of surface cold working (SCW) and bending fatigue limit of chromium-nickel austenitic stainless steels (CNASS). The results of experimental tests and optimization of the SCW process, implemented via hardening diamond burnishing (DB), are presented. When the requirement for the corresponding component is a high fatigue limit, the information obtained will help the researcher to find the inverse correlation between SI and finishing so that when the SCW process is implementing by another method, the same high fatigue limit can be achieved. Five roughness parameters that are functionally significant indicators of fatigue behavior, microhardness, and surface residual axial and hoop stresses form the vector of objective functions. The governing factors are the burnishing force and the number of passes. The fatigue limit was obtained by the accelerated Locati’s method. The models of the corresponding SI characteristics and the fatigue limit were obtained by a planned experiment and regression analyses. Direct correlations between SI characteristics and the fatigue limit were obtained by eliminating the variables in the corresponding pairs of models. The change trends of the microhardness and fatigue limit were found to be identical, i.e., the fatigue limit of CNASS can be controlled via inexpensively measured SI characteristics such as roughness parameters and surface microhardness. In other words, any static coldworking process can be optimized without carrying out fatigue tests by choosing these SI characteristics as objective functions and seeking a compromise optimal solution that simultaneously achieves high values of the microhardness and skewness and a low value of the roughness parameter Ra. Given the direct correlation between the microhardness and the fatigue limit, the compromise optimal solution maximizes the fatigue limit while satisfying the particular roughness requirements. The multi-objective optimization performed and comparisons made prove the effectiveness of the proposed approach.

Abstract
Background
sFlt-1/PlGF ratio has been proposed to herald adverse Pregnancy outcome (APO). Several authors have proposed the use of a continuous scale but most use specific cut-offs to evaluate the risk of APO, but the proposed range varies widely. The aim, is to evaluate if the Maternal adverse outcome (AO) prediction occurs in a stepwise manner, and if this was the case, which would be the point yielding the highest accuracy.
Methods
This is an observational retrospective cohort study. Singleton pregnancies, between 20 to 40 weeks were selected according the levels of sFlt-1/PlGF; three groups (n = 60 each): High ≥ 655, Intermediate ≥ 85 to < 655 and Low < 85. From hospital records we retrieve data, and outcome, also we quantitate the PE risk. We compared the groups, to determine the clinical utility of the sFlt1/PlGF ratio in prediction of Maternal AO, we used ROC analysis, and to develop a predictive model of Maternal AO a binary multivariate logistic regression was used.
Results
At entry a different degree of severity is observed for groups: High > Intermediate > Low, for: Systolic Blood pressure, Mean Blood pressure, Angiogenic markers, AST, ALT. Also a positive correlation was found between the sFlt-1/PlGF and the afore mentioned variables. We observed a potency order for the Maternal AO, from more to less manifestations High > Intermediate > Low (p < 0,001). sFlt1/PlGF ratio has the highest AUC for predicting Maternal AO than any other single parameter.

Published: August 2023

Abstract
Objective
The aim of this study was to determine whether serum vitamin D levels are associated with H. pylori infection and whether low serum vitamin D levels are an independent risk factor for H. pylori infection.
Methods
We conducted a retrospective analysis of a multicenter cohort study from 2017 to 2019. A total of 415 H. pylori + patients and 257 H. pylori- patients aged between 18 and 75 years with both 13C-urea breath test and serum vitamin D level results were included from four hospitals. A questionnaire was used to collect information on potential factors influencing H. pylori infection.
Results
Serum vitamin D levels were significantly lower in the H. pylori + group than in the H. pylori- group (16.7 ± 6.6 ng/ml vs 19.2 ± 8.0 ng/ml, p < 0.05). Using a cutoff value of 20 ng/ml, the H. pylori infection rate was significantly higher in the vitamin D-deficient group (< 20 ng/ml) than in the vitamin D-sufficient group (≥ 20 ng/ml) (66.5% vs 51.0%, p < 0.05). Ordered logistic regression analysis showed that serum vitamin D levels < 20 ng/ml (OR: 1.644, 95% CI: 1.154–2.342), higher education levels (OR: 1.774, 95% CI: 1.483–2.119), household size ≥ 4 (OR: 1.516, 95% CI: 1.081–2.123), and lower household income (OR: 1.508, 95% CI: 1.289–1.766) were independent risk factors for H. pylori infection.
Conclusion
Lower serum vitamin D levels may be associated with an increased risk of H. pylori infection, and lower serum vitamin D levels are an independent risk factor for increasing H. pylori infection rates. Randomized controlled trials are needed to determine whether supplementation with vitamin D can reduce H. pylori infection rates.
