SMALL BUSINESS SUPPORT POLICY IN LATVIA

2016

Economic growth is the important factor for improving competitiveness and to ensure the availability of financial resources at all stages of business development. The authors explore European Union activities to promote the development of small and medium enterprises, the Latvian business environment, the regulatory framework, the accounting regulatory framework for small and medium enterprises. The research study included an assessment of the business environment in the international context for the years 2010 – 2016, national support programmes providing financial resources, their availability and tax policy guidelines for small and medium enterprises. The research study results are summa…

Seminar groups as part of first-semester mathematics teaching: What did the students learn?

2018

International audience; In this study, the learning encouraged by teaching activities in a small-group setting was investigated through the analysis of students' responses to survey and interview questions. The results indicate that the students perceived an increased ability to communicate mathematics in written form, but to a lesser extent developed their ability to discuss mathematics and build conceptual understanding.

Team communication in the workplace

2019

In today’s organizations, team and group communication is an essential part of work, and it is loaded with expectations. Despite the expectation that teamwork offers an answer to the intense demands of today’s dynamic, ubiquitously digital working life, taking advantage of its benefits is neither simple nor well understood. Teams represent various types of collaboration. Teams can be understood by observing their structures, practices, and processes as well as their functionality and goal achievement. This chapter provides an understanding of the multifaceted reality of groups and teams as it manifests in interaction. The chapter analyzes a variety of team phenomena in order to enhance and …

An original control strategy of storage systems for the frequency stability of autonomous grids with renewable power generation

2021

This work examines the operation of the autonomous power system of a geographical island assuming the integration of significant generation shares from renewable energy sources and the installation of the required storage systems. The frequency stability of the system is investigated considering different operating conditions, in terms of load demand and renewable power generation. The main focus of the work is an original control strategy specifically designed for power converters interfacing storage units to the grid. The proposed strategy is based on an extended frequency droop control, which selects specific droop settings depending on the operating mode—charge or discharge—of the stora…

snoRNPs Regulate Telomerase Activity in Neuroblastoma and Are Associated with Poor Prognosis

2013

AbstractAmplification of the MYCN oncogene is strongly associated with poor prognosis in neuroblastoma (NB). In addition to MYCN amplification, many studies have focused on identifying patients with a poor prognosis based on gene expression profiling. The majority of prognostic signatures today are comprised of large gene lists limiting their clinical application. In addition, although of prognostic significance,most of these signatures fail to identify cellular processes that can explain their relation to prognosis. Here, we determined prognostically predictive genes in a data set containing 251 NBs. Gene Ontology analysis was performed on significant genes with a positive hazard ratio to …

Demand Response for Integrating Photovoltaic Plants in Lampedusa Island

2021

This paper presents the results of a simulation study concerning different Demand Response logics applied to Electric Storage Water Heaters on the island of Lampedusa. Electric Storage Water Heaters are the devices that are primarily used on the island to produce domestic hot water. Starting from measured load profiles collected in Lampedusa, a domestic hot water consumption profile was derived, to simulate the energy usage of the Storage Water Electric Heaters during the day. This work was carried out as a preliminary feasibility study for the BloRin project, financed by cohesion funds in the Sicilian region. According to the project, which also includes the installation of domestic photov…

Conformation of a chain polyelectrolyte in solution with low molecular weight salt: small angle neutron scattering measurements

1986

Small angle neutron scattering measurements have been carried out on the tetramethylammonium salt of the polystyrenesulfonic acid withDP w =310 and 1060 in water solution with tetramethylammonium chloride with ionic strength between 0.02 M and 1.0 M. The scattering curves in the scattering vector range 0.05 nm−1≤Q≤1.8nm−1 have been fitted using the form factor of a worm-like chain of finite thickness. The conformational parameters mean square radius of gyration, statistic chain element, mass per unit length and mean square radius of the cross-section have been determined experimentally and used for describing the conformation of the coils. By these molecular weights and ionic strengths, exc…

Nickel induces intracellular calcium mobilization and pathophysiological responses in human cultured airway epithelial cells.

2009

Abstract Environmental exposure to nickel is associated to respiratory disorders and potential toxicity in the lung but molecular mechanisms remain incompletely explored. The extracellular Ca 2+ -sensing receptor (CaSR) is widely distributed and may be activated by divalent cations. In this study, we investigated the presence of CaSR in human cultured airway epithelial cells and its activation by nickel. Nickel transiently increased intracellular calcium (−log EC 50  = 4.67 ± 0.06) in A549 and human bronchial epithelial cells as measured by epifluorescence microscopy. Nickel (20 μM)-induced calcium responses were reduced after thapsigargin or ryanodine exposure but not by Ca 2+ -free medium…

L'ecomuseo del grano e del pane: un percorso progettuale centrato sul design

2018

La festa di S. Giuseppe, oltre che un’importante e sentita ricorrenza religiosa, è a Salemi soprattutto la “festa dei pani”; bellissime realizzazioni di alto artigianato artistico, la cui sapienza si tramanda nelle famiglie e nelle associazioni di donne che per mesi lavorano alla produzione dell’enorme quantità delle piccole e grandi forme di pane, per rivestire le costruzioni votive che accolgono il rito della cena. Nasce quindi l’idea di proporre un “Ecomuseo del grano e del pane” nel Collegio dei Gesuiti, valorizzando e riaprendo al pubblico uno spazio di grande interesse storico-architettonico. Nell’ambito della consolidata collaborazione del Comune di Salemi con il Dipartimento di Arch…
