Reciprocal regulation of the human sterol regulatory element binding protein (SREBP)-1a promoter by Sp1 and EGR-1 transcription factors.
2007
AbstractSterol regulatory element binding protein (SREBP)-1a is a transcription factor that is highly expressed in actively growing cells, and is involved in the biosynthesis of cholesterol, fatty acids and phospholipids. We have mapped the minimal human SREBP-1a promoter region to 75bp upstream of the translation start site where we discovered a functional role for the 3 GC-boxes containing overlapping sites for the Sp1 and EGR-1 transcription factors. Intact SP1-binding sites are essential for promoter activity, whereas EGR-1 suppresses the transcription of the human SREBP-1a promoter. These results reveal a novel physiologically relevant transcriptional mechanism for the reciprocal regul…
Thermodynamics of electrokinetic processes—II. systems with different kinds of electrodes
1990
Abstract In this work Haase's Formulation of Electrokinetic Processes is applied to special systems: those working with two different electrodes and those where gaseous phases are formed. Phenomenological equations are always written in terms of directly observable variables. The extrinsic character of Haase's Formulation is clearly shown. Some special results on streaming current in dielectric liquids are explained.
Editorial: Is There Still Something to Learn about the Association of Corporate Governance with Firm Performance?
2016
The association of Corporate Governance (CG) with Firm Performance (FP) has always been an issue relevant to management literature, despite the notable heterogeneity of studies and their mixed results highlighting the opportuneness of continuing to investigate the association of CG with FP. The article aims to contribute to this lively debate by pointing out the main causes of the mixed findings and the contributions of three papers which, in the authors’ opinion, add knowledge to the CG-FP research stream, which deserves more empirical research, as there is still something to learn about this association. us possibilities of majorly used social media websites and the products which are be…
Testing mechanical characteristics of chestnut stakes used in bed sills for stream restoration
2017
Using of wood elements for constructing bed sills in Mediterranean streams, where the banks are not protected by tree vegetation, needs an evaluation of biological and mechanical characteristics for evaluating both the wood durability and the effectiveness of the stream restoration project. Very few studies have dealt both with the decay of mechanical characteristics of wood elements employed for stream restoration works and with the changes over time of physical and chemical wood characters. In this paper, for a wood and stone bed sill located in a stream having no shaded banks, the changes of physical and chemical characters detected after 12, 18, 24, 30, 36, 42 and 48 months on chestnut …
Wave Energy Assessment along Sicilian Coastline, Based on DEIM Point Absorber
2017
The use of renewable energy sources is one of the most relevant goals to be achieved in order to match the climate protection targets. As a case study, the paper shows the current electrical energy production by sources in the Sicilian context. Among the renewable energy sources, the paper investigates the wave energy potential along the Sicilian coasts, because of the favorable climate around the island. A point absorber is present in order to exploit this source. Two scenarios are presented, with two different levels of energy production.
The Future of ERP Systems: look backward before moving forward
2012
Abstract This paper explores the enterprise resource planning (ERP) systems literature in an attempt to elucidate knowledge to help us see the future of ERP systems’ research. The main purpose of this research is to study the development of ERP systems and other related areas in order to reach the constructs of mainstream literature. The analysis of literature has helped us to reach the key constructs of an as-is scenario, those are: history and development of ERP systems, the implementation life cycle, critical success factors and project management, and benefits and costs. However, the to-be scenario calls for more up-to-date research constructs of ERP systems integrating the following co…
Assessment of data and parameter uncertainties in integrated water-quality model
2011
In integrated urban drainage water quality models, due to the fact that integrated approaches are basically a cascade of sub-models (simulating sewer system, wastewater treatment plant and receiving water body), uncertainty produced in one sub-model propagates to the following ones depending on the model structure, the estimation of parameters and the availability and uncertainty of measurements in the different parts of the system. Uncertainty basically propagates throughout a chain of models in which simulation output from upstream models is transferred to the downstream ones as input. The overall uncertainty can differ from the simple sum of uncertainties generated in each sub-model, dep…
Experienced knowledge for the description of maintenance packages
2015
International audience; The presented work is included in the research theme that specifies some means of capitalization andexploitation of knowledge from experience feedback processes in the context of industrial maintenancemanagement. Our research on it is a more precise definition of the proposed project, built with a problemasking how to handle the management of repair packages. Upstream, the knowledge of various expertsare materialized in the form of expert reports. Downstream maintenance wants to quickly repair productsbased on symptoms or change parts in advance. For this, we propose a methodology by analysing thefeedback to improve the response time for maintenance services. This is…
The Contribution of TQM to Organizational Ambidexterity: The State of the Art and Promising Research Streams
2015
The purpose of this chapter is to present the state of the art of research on the impact of TQM implementation on organizational ambidexterity. The widespread diffusion of TQM in organizations in all sectors and the already established importance of ambidextrous capability for achieving long-term competitiveness make understanding the connection between both fields a worthwhile objective. We underline the need to include in the analysis the broad and complex nature of TQM. Due to the interactions between its principles and practices, total quality management can act as a platform in creating an ambidextrous organizational context. We also underline the importance of clarity in research on t…
The identifiability analysis for setting up measuring campaigns in integrated water quality modelling.
2012
Abstract Identifiability analysis enables the quantification of the number of model parameters that can be assessed by calibration with respect to a data set. Such a methodology is based on the appraisal of sensitivity coefficients of the model parameters by means of Monte Carlo runs. By employing the Fisher Information Matrix, the methodology enables one to gain insights with respect to the number of model parameters that can be reliably assessed. The paper presents a study where identifiability analysis is used as a tool for setting up measuring campaigns for integrated water quality modelling. Particularly, by means of the identifiability analysis, the information about the location and …
