Immobilization of single-stranded DNA fragments to solid surfaces and their repeatable specific hybridization : covalent binding or adsorption ?
2004
Abstract The different steps of the immobilization process of single-stranded DNA (ssDNA) on surfaces by means of chemical grafting have been investigated using systematic measurements of grafting and hybridization densities by means of radioactive labelling. The immobilization by chemical grafting to a dense monomolecular layer of N-hydroxysuccinimidyl ester reactive functions attached to silica plates was performed from a dilute solution of amino-terminated oligonucleotides (10 μmol/l). The slow evaporation of the solvent allowed to increase the DNA grafting density by a factor of 10. A precise control of the rinsing process that followed the immobilization reaction allowed the discrimina…
Tax incentives to encourage corporate investment in Latvia
2020
During 2006‐2017, Latvia has applied a rather generous accelerated depreciation (AD) policy to stimulate firm investment. The AD policy included: (1) the general AD scheme, (2) incentives to acquire new technological equipment, and (3) Investment incentives in the specially assisted areas. This paper analyses the effect of accelerated depreciation policy on firm investment using administrative firm‐level data for 2007–14. Lacking data for a natural experiment (AD began before our sample period), we use difference‐in-differences methodology with identification based on variation either across time (the crisis period serving as quasi‐counterfactual) or by firm size (with large firms unlikely …

Sustainability Assessment of Agricultural Systems in Paraguay: A Comparative Study Using FAO’s SAFA Framework
2019
Sustainability is a topic that is at the center of current discussions in the political, economic, social, and environmental fields. For its analysis, an integral and multidisciplinary vision is needed. This work aims to assess the sustainability of agricultural systems in Paraguay through a comparison applying SAFA (Sustainability Assessment of Food and Agriculture Systems) indicators. The research focuses on 15 case studies on the territory of the Eastern Region of Paraguay divided into five classes of agricultural systems: agribusiness, conventional peasant family farming, agroecological peasant family farming, neo-rural farming, and indigenous agriculture. Data were collected through in…
The importance of social value in agroecological farms: adjusting the common good balance sheet to improve their sustainable management
2021
Organic farming offers the producers the possibility of focusing on their business while obtaining a competitive advantage. Nevertheless, this is centered in specific activities of the production process, thus only creating environmental value. Therefore, it is not an approach based on sustainability. As a consequence of this, it becomes necessary to enlarge this approach toward people (social value) and profitability (economic value). The objective of this work is to describe a tool based on the Economy for the Common Good model applied to the agroecological sector. We propose to adapt the Common Good Matrix to the characteristics of agroecological farms to offer a useful tool to manage an…

Nasdaq Baltic kapitāla un parāda vērtspapīru tirgus un tā attīstības iespējas
2020
Bakalaura darba tēma ir „Nasdaq Baltic kapitāla un parāda vērtspapīru tirgus un tā attīstības iespējas”. Temata aktualitāti autors pamato ar relatīvi zemo vērtspapīru tirgus kapitalizāciju Latvijā un Baltijā kopumā, tirgus nozīmi valstu tautsaimniecībā un tā ietekmi ekonomiskās izaugsmes nodrošināšanā. Bakalaura darbā tiek analizēts akciju un parāda vērtspapīru tirgus teorētiskie aspekti un to nozīme ekonomikā, sākotnējā publiskā vērtspapīru piedāvājuma nozīme un sekundārais vērtspapīru tirgus. Tiek izpētīta Latvijas vērtspapīru tirgus līdzšinējā attīstība līdz Nasdaq Baltic izveidei, analizējot kopējo Nasdaq Baltic emitentu struktūru, akcentējot Latvijas tirgus daļu, identificējot un klasi…
Practitioners’ Perceptions of Co-Product Allocation Methods in Biorefinery Development—A Case Study of the Austrian Pulp and Paper Indust…
2022
The utilization of coproducts is a strategy that can be applied to increase the economic and environmental performance of industrial processes and thus reach an objective targeted in several environmental policies. In multi-output production processes, allocation needs to be performed to assess the products’ environmental and economic performance. It is crucial to choose an adequate allocation method, because this choice has been shown to strongly influence overall outcomes. Consequently, rash choices can lead to poor decision-making. Various ways to apply and combine allocation methods can be found in the academic literature, but it is often difficult to find sufficient guidance on how to …
