This section is devoted to the study of the measuring area in which topology set X is produced by an unused scalar known as metric that can be defined as a measurement of a particular distance between any two parts, or focused, in the setting as part of its properties strongly suggests the natural concept of distance we usually experience. In everyday life. This type of climatic space includes a popular position among all technological spaces because the reason is that its topology has been completely removed by scale-level work. We can confidently assume that we are well acquainted with the characteristics of such work and are accustomed to handling it. All things being equal, perfect topology is often commended by a certain category of a small dynamic subset of a theoretical set. The concept of measurement space was first introduced by Fréchet in the year 1906. However, the name of the metric space was given by Hausdorff later.

AbstractNanotechnology allows for the development of new types of materials containing antimicrobial properties. Nanocomposite-based products are increasingly applied in medicine, industry and everyday life. Antibacterial features allow the use of nanoproducts in filters for water and air purification, textiles, food packages, medical materials and devices, ceramics, glass, plastics, paints, cosmetics and personal care products. Numerous studies concern the synthesis of novel antimicrobial nanoproducts as well as modification of already existing nanomaterials in order to supply them with antibacterial activity. However, some problems related to the potential emission of nanocomponents into the environment can appear and should be considered.

This paper gives a short review of some basics of metric spaces, the concept of continuity of these metric spaces, with a comparison of it with uniform continuity and convergence. In addition to this, it includes a discussion of some past work of researchers on metric space, its generalization, and useful results made by them with applications using these spaces.

This paper examines the interaction between state power and the everyday life of ordinary Chinese Singaporeans by looking at the Hungry Ghost Festival as a contested category. The paper first develops a theoretical framework building on previous scholars’ examination of the contestation of space and the negotiation of power between state authorities and the public in Singapore. This is followed by a short review of how the Hungry Ghost Festival was celebrated in earlier times in Singapore. The next section of the paper looks at the differences between the celebrations in the past and in contemporary Singapore. The following section focuses on data found in local newspapers on Getai events of the 2017 Lunar Seventh Month. Finally, I identify characteristics of the Ghost Festival in contemporary Singapore by looking at how Getai is performed around Singapore and woven into the fabric of Singaporean daily life.

Selected area electron diffraction (SAD) has been used successfully to determine crystal structures, identify traces of minerals in rocks, and characterize the phases formed during thermal treatment of micron-sized particles. There is an increased interest in the method because it has the potential capability of identifying micron-sized pollutants in air and water samples. This paper is a short review of the theory behind SAD and a discussion of the sample preparation employed for the analysis of multiple component environmental samples.

The most advanced macromolecular materials are found in plants and animals, and certainly the connective tissues in mammals are amongst the most advanced macromolecular composites known to mankind. The efficient use of collagen, a fibrous protein, in the design of both soft and hard connective tissues is worthy of comment. Very crudely, in bone collagen serves as a highly efficient binder for the inorganic hydroxyappatite which stiffens the structure. The interactions between the organic fiber of collagen and the inorganic material seem to occur at the nano (scale) level of organization. Epitatic crystallization of the inorganic phase on the fibers has been reported to give a highly anisotropic, stress responsive, structure. Soft connective tissues also have sophisticated oriented hierarchical structures. The collagen fibers are “glued” together by a highly hydrated gel-like proteoglycan matrix. One of the simplest structures of this type is tendon which functions primarily in uniaxial tension as a reinforced elastomeric cable between muscle and bone.

Abstract The Popeye domain-containing gene family encodes a novel class of cAMP effector proteins in striated muscle tissue. In this short review, we first introduce the protein family and discuss their structure and function with an emphasis on their role in cyclic AMP signalling. Another focus of this review is the recently discovered role of POPDC genes as striated muscle disease genes, which have been associated with cardiac arrhythmia and muscular dystrophy. The pathological phenotypes observed in patients will be compared with phenotypes present in null and knockin mutations in zebrafish and mouse. A number of protein–protein interaction partners have been discovered and the potential role of POPDC proteins to control the subcellular localization and function of these interacting proteins will be discussed. Finally, we outline several areas, where research is urgently needed.

In this paper, I will illustrate the changing nature and complexity of faculty employment in college and university settings. I will use existing higher education research to describe changes in faculty demographics, the escalating demands placed on faculty in the work setting, and challenges that confront professors seeking tenure or administrative advancement. Boyer’s (1990) framework for bringing traditionally marginalized and neglected functions of teaching, service, and community engagement into scholarship is examined as a model for balancing not only teaching, research, and service, but also work with everyday life.

Abstract. Given the fact that most of the dark personality measures are developed based on data collected in low-stake settings, the present study addresses the appropriateness of their use in high-stake contexts. Specifically, we examined item- and scale-level differential functioning of the Short Dark Triad (SD3; Paulhus & Jones, 2011 ) measure across testing contexts. The Short Dark Triad was administered to applicant ( N = 457) and non-applicant ( N = 592) samples. Item- and scale-level invariances were tested using an Item Response Theory (IRT)-based approach and a Structural Equation Modeling (SEM) approach, respectively. Results show that more than half of the SD3 items were flagged for Differential Item Functioning (DIF), and Exploratory Structural Equation Modeling (ESEM) results supported configural, but not metric invariance. Implications for theory and practice are discussed.
