Published: February 2024

Background: Preoperative fasting is a procedural measure implemented before surgery or anesthesia to avert regurgitation or vomiting. PONV incidence is influenced by surgical, anesthetic, and patient-related factors. The purpose of the study is to ascertain the duration of preoperative fasting observed by participants and the prevalence of PONV according to personality traits. Purpose: Determine the correlation between the duration of preoperative fasting and the occurrence of PONV in patients undergoing general anesthesia at RSUD Dr. Soekardjo Tasikmalaya. Methods: Observatory, descriptive, and cross-sectional designs are utilized. The sampling method was with sixty respondents ranging in age from seventeen to forty-five years, ASA I to II. Data is collected via observation and evaluation. Findings: The study observed that among 37 individuals (61.7%), preoperative fasting for 6-8 hours was beneficial, while for 23 individuals (38.3%), fasting for >8 hours were detrimental. At the age of 17-25 years, 10 individuals (47.6%) develop PONV, while 11 individuals (52.4%) do so between the ages of 26-45. Among women, 17 individuals (81.0%) have PONV, while 20 individuals (95.2%) have ASA I physical status, and 1 individual (4.8%) has ASA II physical status. Conclusion: There is a significant link (p < 0.013) between preoperative fasting time and postoperative nausea and vomiting (PONV) in patients under general anesthesia. Fasting before surgery should be long enough to avoid PONV

Background
Non-suicidal self-injury (NSSI), of which the predisposing factors are complex and diverse, profoundly affects the physical and mental health of young people. Therefore, this work established an NSSI intermediary network model considering the interaction of multiple factors. A mediating effect between attention-deficit/hyperactivity disorder (ADHD) and NSSI, considering the influence of comorbidities, such as depression, anxiety, and impulsive personality, was proposed based on sex differences.

Methods
A total of 2,689 middle school students in Ningbo City, Zhejiang Province, China, were randomly sampled and participated in this study. Data regarding their demographic characteristics, attention deficit, hyperactivity/impulsivity, NSSI, anxiety, depression, internet addiction, and other comorbid symptoms were collected and analyzed. After initially screening the data, variables were assessed for significance using a single-factor inter-group difference analytic method, and a binary logistic regression analysis was performed. The intermediary effect of factors influencing NSSI in males and females was also analyzed.

Results
The overall NSSI rate was 15.16%. The results showed that the impact of individual impulsivity characteristics (impulsiveness, the ADHD with hyperactivity/impulsivity subtype) on NSSI behavior was not significant (regression results, P > 0.05). The degree of association between ADHD with attention deficit and ADHD with comprehension deficit subtypes, and other comorbid symptoms (depression, anxiety, and internet addiction disorder) and NSSI, with odds ratios (ORs) of 7.6/6.42/436.68/3.82/1.86, and 95% bootstrap confidence intervals (CIs) of 4.64, 12.87/3.46, 12.67/137.42, 2659.13/2.32, 6.37/1.31, 2.82, respectively. The results also showed significant effects of ADHD subtypes on comorbid symptoms and the path effects of NSSI (P < 0.01). Among them, the mediating effect was the strongest when anxiety was the mediating variable, and the mediating effect of girls was higher than that of boys.

Conclusion
The results of this work demonstrated the influence of ADHD symptoms on NSSI behavior. Among patients with ADHD, patients with subtypes with obvious attention deficit characteristics were more likely to exhibit NSSI behavior, whereas the hyperactive impulse subtype had no direct impact on NSSI. We conclude that adolescent impulsivity may not be directly related to NSSI behavior and that impulsive characteristics jointly affect NSSI behavior through a series of NSSI comorbid symptoms. Notably, the probability of symptom onset and the degree of comorbidity was significantly higher in girls than in boys of the same age, and girls were more prone to NSSI behavior. These findings provide effective theoretical support for the prevention and treatment of adolescent NSSI behavior.
Fundamentals: Introduction and Survey
Authors: Stein Erwin 
Published: January 2005

Abstract
Volume 1, ‘Fundamentals’, contains 26 chapters with the basic methodological, analytical, algorithmic, and implementation topics and aspects of computational mechanics, written by well‐known mathematicians, mechanicians, engineers, and computer scientists.
It shall provide basic knowledge and tools as well as background information for Volumes 2 and 3, devoted to solid and structural mechanics as well as to fluid dynamics.

Volume 1 is structured as follows: the first 14 chapters treat
discretization methods
with error‐controlled adaptivity for elliptic problems, as finite differences, finite elements, boundary elements, mixed elements, finite volume elements, discontinuous elements, spectral methods, and wavelet techniques, followed by 3 chapters on
geometrical modeling, mesh generation, and visualization
. The next five chapters present solvers of algebraic equation systems, with emphasis on linear systems including eigenvalue problems, multilevel techniques, like Multigrid methods, cluster techniques, domain decomposition methods, and solvers for nonlinear systems, especially bifurcation problems. The last group of three chapters is devoted to
time‐dependent problems
, treating parabolic, and hyperbolic initial boundary value problems, especially Galerkin‐type approximations in space and time with duality techniques for the control of accumulation errors in time and thus of the numerical stability. Also boundary element methods are presented for transient parabolic and hyperbolic problems like the heat and diffusion–convection equation, acoustic scattering, and elastic wave propagation. Finally, numerical methods for the time‐harmonic Maxwell equations are presented.

Volume 1 thus is intended to provide a sound theoretical basis with numerous practical algorithms and tools for students, researchers, and practitioners.
Finite Element Methods

Published: January 2005

AbstractThis introductory chapter on the mathematical theory of finite element methods (FEMs) discusses itsh‐version for elliptic boundary value problems in the displacement formulation. Topics addressed range from a priori to a posteriori error estimates and also include weak forms of elliptic PDEs, Galerkin schemes, finite element spaces, adaptive local mesh refinement. Nonconformities and variational crimes as well as algorithmic aspects conclude the chapter.
Spectral Methods
Authors: Canuto Claudio , Quarteroni Alfio 
Published: January 2005

Abstract
Spectral methods represent a family of methods for the numerical approximation of partial differential equations. Their common denominator is to rely on high‐order polynomial expansions, notably trigonometric polynomials for periodic problems, and orthogonal Jacobi polynomials for nonperiodic boundary‐value problems. They have the potential of providing a high rate of convergence when applied to problems with regular data. They can be regarded as members of the broad family of (generalized) Galerkin methods with numerical evaluation of integrals based on Gaussian nodes. In the first part, we introduce the methods on a computational domain of simple shape and analyze their approximation properties as well as their algorithmic features. Next, we address the issue of how these methods can be extended to more complex geometrical domains by retaining their distinctive approximation properties.
Mixed Finite Element Methods
Authors: Auricchio Ferdinando , Brezzi Franco , Lovadina Carlo 
Published: January 2005

AbstractWithin the well‐known and highly effectivefinite element methodfor the computation of approximate solutions of complex boundary value problems, we focus on the often‐calledmixed finite element methods, where in our terminology the word ‘mixed’ indicates the fact that the problem discretization typically results in a linear algebraic system characterized by a null matrix on the main diagonal.Accordingly, the goals of the present chapter are: (1) to sketch out that several physical problems share such an algebraic structure once a discretization is introduced; (2) to present a simple, algebraic version of the abstract theory that rules most applications of mixed finite element methods; (3) to give several examples of efficient mixed finite element methods; (4) finally, to give some hints on how to perform a stability and error analysis, focusing on a representative problem.
Discrete Element Methods
Authors: Bićanić Nenad 
Published: January 2005

AbstractDiscrete element methodscomprise a set of computational modeling techniques suitable for the simulation of dynamic behaviour of a collection of multiple rigid or deformable bodies. Most media can be treated as discontinuous at some level of observation (nano,micro,meso,macro), where the continuum assumptions cease to apply. This happens when the scale of the problem becomes similar to the characteristic length scale of the associated material and the interaction laws between bodies or particles are invoked, instead of the continuum constitutive law. Principal aspects of discrete element methodologies are discussed by considering(a) contact detection algorithm, (b) treatment of contacts, (c) deformability and material model of bodies in contact (rigid, deformable, elastic, elasto‐plastic etc), (d) small strain or large strain formulations, (e) number (small or large) and distribution (loose or dense packing) of interacting bodies, (f) modeling of boundary conditions, (g) possible fracturing or fragmentation and, (h) time stepping integration schemes (explicit, implicit). It is argued that there are many similarities between the apparently different discrete element methods e.g. distinct element method (DEM), discontinuous deformation analysis (DDA), non smooth contact dynamics (NSCD).
ArbitraryLagrangian–Eulerian Methods
Authors: Donea Jean , Huerta Antonio , Ponthot J.‐Ph. , Rodríguez‐Ferran A. 
Published: January 2005

AbstractThe aim of the present chapter is to provide an in‐depth survey of arbitrary Lagrangian–Eulerian (ALE) methods, including both conceptual aspects of the mixed kinematical description and numerical implementation details. Applications are discussed in fluid dynamics, nonlinear solid mechanics and coupled problems describing fluid–structure interaction. The need for an adequate mesh‐update strategy is underlined, and various automatic mesh‐displacement prescription algorithms are reviewed. This includes mesh‐regularization methods essentially based on geometrical concepts, as well as mesh‐adaptation techniques aimed at optimizing the computational mesh according to some error indicator. Emphasis is then placed on particular issues related to the modeling of compressible and incompressible flow and nonlinear solid mechanics problems. This includes the treatment of convective terms in the conservation equations for mass, momentum, and energy, as well as a discussion of stress‐update procedures for materials with history‐dependent constitutive behavior.

Solids and Structures: Introduction and Survey
Authors: de Borst René 
Published: January 2005

Abstract
Volume 2 ‘Solids and Structures’ is concerned with the numerical analysis of solids and structures in the widest possible sense. Utilizing the basic methods outlined in Volume 1 ‘Fundamentals,’ a comprehensive picture is first given of numerical methods for solids and structures in the linear regime. Next, a wide variety of nonlinear theories are discussed, encompassing structural stability problems as well as instabilities that stem from the properties of the constituent materials. The volume also contains chapters that address computational problems that are specific to particular materials such as concrete, soils, composites, and biomaterials, and to forming processes.
Problems in which interaction between fluids and solids plays a role are covered next, for example, multiphase media, fluid–structure interaction, and structural acoustics. Other important topics that are treated include stochastic finite elements, parameter identification, and contact and the analysis of structural problems using boundary element methods.
Finite Element Methods for Elasticity with Error‐Controlled Discretization and Model Adaptivity
Authors: Stein Erwin , Rüter Marcus 
Published: January 2005

AbstractThe essential topics of the finite element method for linear and finite elastic deformations of solids are presented in this chapter from both the mechanical and mathematical point of view.As a starting point, the nonlinear, and linearized theory of elasticity are derived in a rigorous way, followed by the classical variational principles of elasticity, which are the basis for the finite element method in its various forms. More precisely, the discrete variational approach of the (one‐field) Dirichlet minimization principle of the total potential energy is presented, followed by concise representations of the (two‐field) Hellinger–Reissner stationary dual‐mixed principle and the (three‐field) Hu–Washizu stationary mixed principle, including the main features of the associated finite element methods.The main objective of this chapter is the systematic treatment of error estimation procedures and adaptivity for the linearized and finite elasticity problem covering both global and goal‐oriented a posteriori error estimators. The three basic classes, that is, residual‐, hierarchical‐, and averaging‐type error estimators are presented and applied to a fracture mechanics problem as an example.A further challenging topic is the combination of error‐controlled adaptive finite element solutions with hierarchical model and dimension adaptivity of the underlying mathematical model, especially for thin‐walled structures where model expansion is necessary in subdomains with boundary layers and other disturbances.
Computational Fracture Mechanics

Published: January 2005

AbstractThe purpose of this chapter is to survey examples of historical and state‐of‐the‐art approaches of computational fracture mechanics. A global taxonomy of these approaches is defined and used as a roadmap for the chapter. Approaches are described and compared for their use in both the traditional role of computational fracture mechanics – calculation of crack front fields – and in the emerging role of prediction of material‐damage evolution and toughness.
Computational Geomechanics Including Consolidation
Authors: Carter John P. , Small John C. 
Published: January 2005

AbstractA review is presented of the role of computational mechanics in geotechnical engineering. Included are discussions of the conventional deterministic techniques used for numerical modeling in geomechanics and a brief discussion of the stochastic techniques for dealing with the uncertainties encountered in geotechnical practice. Considerable emphasis is given to the methods commonly used for the solution of boundary and initial value problems. Significantly, the chapter also includes a discussion of the limitations of the various numerical modeling techniques. Constitutive modeling of soil and rock mass behavior and material interfaces is an essential component of this type of computing, and so a review of recent developments and capabilities of constitutive models for geomaterials is also included. Problems involving the interaction of the ground with other engineering structures are also addressed. Some of the concepts described in the paper are illustrated with examples taken from research and practice. Emphasis has been placed on the mechanical behavior of soil, but it is noted that many of the models and techniques described also have application in rock mechanics and rock engineering.
