If non-scientific notions are in conformity with the content of scientific concepts the teacher should rely on them forming new concepts, explaining natural phenomena, etc. It contributes to the concept comprehension efficacy. In case non-scientific notions are in collision with the content of scientific concepts they should be corrected as in that case they interfere with the formation of scientific concepts.

Abstract:

The KDamper is a novel passive vibration isolation and damping concept, based essentially on the optimal combination of appropriate stiffness elements, which include a negative stiffness element. The KDamper concept does not require any reduction in the overall structural stiffness, thus overcoming the corresponding inherent disadvantage of the “Quazi Zero Stiffness” (QZS) isolators, which require a drastic reduction of the structure load bearing capacity. Compared to the traditional Tuned Mass damper (TMD), the KDamper can achieve better isolation characteristics, without the need of addition

Purpose: The purpose of this research paper is to explore what constitutes being "born global." We approach the born global phenomenon by applying ideas presented in existing international entrepreneurship, business, and marketing literatures. In addition, the paper illustrates how market orientation is a relevant construct for understanding the existence of born global firms. Market orientation is contrasted with science driven strategies in young, technology based firms and in both domains. In markets as well as in science, both global and local forces influence the behavior of new biotechno

Abstract:

Understanding the concept is an important aspect of solving various physics problems. Understanding the concept will help in understanding the problems, determining problem-solving strategies, and using mathematics appropriately as a problem-solving tool. Lack of conceptual understanding results in the tendency to solve problems by relying solely on formulas without knowing the proper use of formulas according to the underlying concepts of the problem. Various problems related to rotational motion can be explained through the concept of torque. To solve the problem of torque, understanding the

Abstract:

Abstract The gradient wind is defined as a horizontal wind having the same direction as the geostrophic wind but with a magnitude consistent with a balance of three forces: the pressure gradient force, the Coriolis force, and the centrifugal force arising from the curvature of a parcel trajectory. This definition is not sufficient to establish a single way of computing the gradient wind. Different results arise depending upon what is taken to be the parcel trajectory and its curvature. To clarify these distinctions, contour and natural gradient winds are defined and subdivided into steady and

ArgumentAccording to a long-standing interpretation which traces back to Max Jammer'sConcepts of Force(1957), Ruggiero G.

As the wave forces are the function of the wave height, period and the angle between the incoming wave direction and the axis of the discharge pipeline, the resultant wave force is directly related to the alignment of the pipeline. In this paper, a method is explained to determine an optimum pipeline route for which the resultant wave force becomes minimum and hence, the cost of the constructive measures may decrease. Also, the application of this method is submitted through a case study.

The implication of this correlation, referred to here as duality, is that the science of kinematics can be utilized in a systematic manner to yield insight into statics, and vice versa. The paper begins by introducing a unique line, referred to as the equimomental line, which exists for two arbitrary coplanar forces. This line, where the moments caused by the two forces at each point on the line are equal, is used to define the dire

However, only leg compliances were considered in the stiffness matrix method.

The metaphysics of action are distinguished from the metaphysics of intentional action, and it is argued that the former forces an implausible unity on the actions of inanimate nature and of rational agents. Agency in the metaphysics of action adds nothing to state-variable causation. A

Lengthening (eccentric)contractions result in the greatest muscle forces at the lowest relative energetic costs. Eccentric contractions play a key role in storing elastic strain energy which, when recovered in subsequent contractions, has been shown to result in enhanced force, work or power outputs.

This is a reason that it is used within standards for limits states. Examples of standards which use jerk include amusement rides and lifts.

This paper addresses the call for more action-based narratives of grassroot resistance to runaway climate change. At a time when deep changes in society are needed in order to respond to climate change and related sustainability issues, there are calls for greater connectivity between science and society, and for more inclusive and disruptive forms of knowledge creation and engagement. The contention of this paper is that the forces and structures that create a disconnect between science and society must be ‘transgressed’. This paper introduces a concept of Transgressive Action Research as a m

Abstract:

Abstract The mitonuclear species concept hypothesizes that incompatibilities between interacting gene products of the nuclear and mitochondrial genomes are a major factor establishing and maintaining species boundaries. However, most of the data available to test this concept come from studies of genetic variation in mitochondrial DNA, and clines in the mitochondrial genome across contact zones can be produced by a variety of forces. Here, we show that using a combination of population genomic analyses of the nuclear and mitochondrial genomes and studies of mitochondrial function can provide i

Abstract:

AbstractThe concept of “relative autonomy” is now routinely used by Marxist and non-Marxist students of public policy to describe the state's independence from class forces. A rare attempt to use the concept empirically is Carl J. Cuneo's work on Canadian unemployment insurance (UI) in the 1930s. This article argues that Cuneo focusses too narrowly on class struggle, and thus misses important aspects of Canadian UI policy. Relative autonomy must be more broadly conceived in terms of the state's administrative expertise, fiscal capacity, and jurisdictional divisions. It is constituted within, n

Abstract:

Although the role of reciprocity in international cooperation is central to neoliberal institutionalism, empirical understanding of the concept remains weak. We analyze strategic response patterns—the use of reciprocity or inverse response (bullying)—in the Bosnia conflict from 1992 to 1995. We construct weekly time series of conflict and cooperation among the parties to the Bosnia war, using machine-coded events data. Time-series statistical analysis identifies several important patterns of strategic response, both reciprocal and inverse. These include bilateral responses, which are central t

Prolonged hostilities on the territory of Ukraine have a destructive effect on the psychological health of the country population, and participants of the joint force operation are particularly affected. In national science, impacts of hostilities on people are studied deeply: participation in the Joint Forces (JF) operation can lead to personality maladaptation, which affects mental health and hinders social adaptation. The consequences of hostilities for people, in particular links between self-concept disharmony and manifestations of socio-psychological adaptation / maladaptation experience

Abstract:

This work seeks to solve one of the basic problems in chemistry learning: understanding the chemical bond as a dynamic equilibrium between attractive and repulsive forces. This force-based model is difficult to grasp, as there are no analogues from everyday life for both attractions and repulsions happening simultaneously. In addition, current teaching approaches often mislead by using mainly the ‘octet rule’ heuristic. As a result, students construct naïve models of the chemical bond, usually viewing atoms as solid balls that are attached to each other in order to “achieve an octet.” To repre

The Covid-19 pandemic forces learning activities to change from classroom learning to online-based learning. Based on the results of the interview, it was found that the teachers at Nurul Fadhilah school did not yet have the readiness to manage online teaching and learning activities, especially in science subjects. The influencing factors are (1) understanding of basic science concepts (physics, chemistry, biology), (2) understanding of systematic online learning management and (3) mastery of Learning Management System (LMS) technology. Therefore, the aim of this activity is to implement LMS

We propose the solution concept of directional equilibrium for the multidimensional model of voting with general spatial preferences. This concept isolates alternatives that are stable with respect to forces applied by all voters in the directions of their gradients, and it extends a known concept from statistics for Euclidean preferences. We establish connections to the majority core, Pareto optimality, and existence and closed graph, and we provide non-cooperative foundations in terms of a local contest game played by voters.

New museology as a system of views was formed in the 1980s. It was the result of comprehending the many and remarkably diverse regional experiences of creating new museums. They arose on the initiative of individual communities and actualized the values that were represented by the elements of the heritage of certain groups of the population. This is how museums focused on social relations were born. Even though the main texts of the ideologists of the new museology were published in the fi rst half of the 1990s, interest in it is not diminishing. Many modern specialists again pay attention to

Abstract:

Previously, a physically-based elastic model has been used in the modeling of high temperature polymer deformation. While this has been successful in producing realistic shapes and forces in necking polymers, the elastic nature of the theory causes some discrepancies between the predictions and the experimental observations. The theory does not describe the observed rate dependence of drawing forces, and at some stages of deformation the predicted inhomogeneity is greater than is observed. The latter effect is the result of the elastic theory’s ability to change instantaneously from a homogene

The ecosystem-based fisheries assessment (EBFA) approach to evaluate four management objectives: sustainability, biodiversity, habitat quality, and socio-economic benefits, has been developed in previous studies. The existing EBFA approach is a risk-based assessment framework and was designed to assess the impacts of fisheries on offshore ecosystems. This approach only considers one driving force of wild capture fisheries. However, in coastal ecosystems, there are a number of anthropogenic activities. In this study, we propose an extended EBFA approach that incorporates the effects of capture
