Environmental remediation using nanomaterial as adsorbents for emerging micropollutants

2023

Water shortage and scarcity are issues of global concern. Water pollution caused by organic micropollutants further aggravates the problem, by rendering an already scarce resource unfit for human consumption. The existing conventional wastewater treatment methods and infrastructure were not designed to eliminate micropollutants. Therefore, their inefficiencies call for modern methods for removing emerging micropollutant residues such as Active Pharmaceutical Ingredients (APIs), Endocrine Disrupting Compounds (EDCs), personal care products and pesticides. The use of nanomaterials, for the abatement of micropollutants in water is gaining traction in recent years, due to the abundance of susta…

The effects of two-way communication and chat service usage on consumer attitudes in the e-commerce retailing sector

2018

In e-commerce retailing (e-retailing), where competitors are only one click away and prices are easy to compare, providing superior customer service and reciprocal communication via a company’s website are important aspects of attracting and retaining customers. One increasingly popular solution to improve customer service is a “live chat” interface that allows consumers to have real-time conversations online with customer service agents. As the literature on the impacts of real-time communication via live chat is currently very limited, this study develops and tests a model that demonstrates the moderating effects of a chat service on the relationship between two-way communication (i.e., a…

Media management and economics research in Northern Europe

2020

Researchers and academics in media economics and management with a Northern European affiliation have played a major role in the development of the field and in creating strong international networks, including The World Media Economics and Management Conference (WMEMC) and European Media Management Association (emma). The chapter provides an overview of media management and economics research in this geographical region. peerReviewed

Mouse models of cytomegalovirus latency: overview.

2002

Abstract Background: The molecular regulation of viral latency and reactivation is a central unsolved issue in the understanding of cytomegalovirus (CMV) biology. Like human CMV (hCMV), murine CMV (mCMV) can establish a latent infection in cells of the myeloid lineage. Since mCMV genome remains present in various organs after its clearance from hematopoietic cells first in bone marrow and much later in blood, there must exist one or more widely distributed cell type(s) representing the cellular site(s) of enduring mCMV latency in host tissues. Endothelial cells and histiocytes are candidates, but the question is not yet settled. Another long debated problem appears to be solved: mCMV establ…

Genomic structure and promoter analysis of pathogen-inducedrepatgenes fromSpodoptera exigua

2009

The repat gene family encodes midgut proteins overexpressed in response to pathogen infection in the lepidopteran Spodoptera exigua. Up-regulation of repat genes has been observed after challenging the larvae with both Bacillus thuringiensis toxins and after infection with the baculovirus Autographa californica multiple nucleopolyhedrovirus. In our study, PCR amplification of the genomic region and genome walking were used to obtain the genomic structure and the sequence of the 5'-upstream region of repat1 and repat2, two of the most phylogenetically distant members of the repat family. A similar gene structure between repat1 and repat2 has been found, with conserved exon-intron positions a…

Baculovirus-mediated immediate-early gene expression and nuclear reorganization in human cells

2007

Baculovirus, Autographa californica multiple nucleopolyhedrovirus (AcMNPV), has the ability to transduce mammalian cell lines without replication. The general objective of this study was to detect the transcription and expression of viral immediate-early genes in human cells and to examine the interactions between viral components and subnuclear structures. Viral capsids were seen in large, discrete foci in nuclei of both dividing and non-dividing human cells. Concurrently, the transcription of viral immediate-early transregulator genes (ie-1, ie-2) and translation of IE-2 protein were detected. Quantitative microscopy imaging and analysis showed that virus transduction altered the size of …

Anàlisi sobre la figura/institució del Comissionat del menor: Pare d'Òrfens contemplada a la Llei 12/2008 de Protecció a la infància i l'adolescència…

2012

The concept / institution of the Commissioner for Children ' 'Pare d'Òrfens' appears for the first time in Valencia with Law 12/2008 on Protection of Children and Adolescents. The purpose of this article is to inform readers of the existence of this concept / institution, analysing the regulatory development that has taken place and comparing its performance with other similar concepts/institutions existing in other Spanish regions, in order to critically assess the work done in recent years. To close the paper, we give a number of conclusions drawn after completing the research on this concept / institution, including several general recommendations in the form of constructive criticism.
