Pasaules un Eiropas Savienības valstīs reģionāli hidroģeoloģiskie modeļi (HM) apkopo ģeoloģisko un ģeogrāfisko informāciju, kuru izmantojot, var aprēķināt sarežģītus telpiskus pazemes ūdens līmeņu un plūsmu sadalījumus, kā arī pazemes un virszemes (upju, ezeru) ūdensobjektu mijiedarbību. Izmantojot reģionālos HM, var racionāli plānot valsts ūdens resursu ilgtspējīgu izmantošanu. Izmantojot lokālus detalizētus HM, kurus iegūst, papildinot reģionālā HM datus, var efektīvi veikt vides un dabas aizsardzības un atveseļošanas darbus. Rīgas Tehniskās universitātes (RTU) Vides modelēšanas centra (VMC) zinātnieki 2011.–2015. gadā izveidoja Latvijas HM (LAMO) versijas: LAMO1→LAMO2→LAMO3→LAMO4. Versija LAMO4, kas dod nozīmīgus HM iespēju un rezultātu kvalitātes uzlabojumus, tika pārbaudīta laikā no 2016. gada līdz 2018. gadam, īstenojot pazemes ūdens procesu pētījumus (kas iespējami tikai reģionālā HM vidē) un risinot praktiskus uzdevumus, izmantojot lokālus HM. LAMO4 dati, kas veido ģeotelpiskās informācijas kopu,  ir brīvi pieejami RTU VMC tīmekļa vietnē. Šie unikālie dati jāievieto portāla “geolatvija.lv” iedaļā “Hidroģeoloģiskie dati” kā valsts budžeta finansēts bezmaksas pakalpojums. Izmantojot LAMO4 aprēķinātos datus par upju pazemes pietecēm, var izveidot Latvijas upju tīkla datormodeli upju piesārņošanas procesu pētīšanai. Ir iespējama LAMO4 pilnveidošana – LAMO4→LAMO5→LAMO6 –, kas ietver HM detalizācijas uzlabošanu un pazemes ūdens kvalitātes ievērošanu. RTU ir īstenojusi LAMO projektu, izmantojot Eiropas Reģionālā attīstības fonda (2011.–2012. g.) un valsts pētījumu programmas “EVIDEnT” (2014.–2018. g.) finansējumu.  Regional hydrogeological models (HM) are founded on geological and geographical information of a country. By processing this information, HM can provide complex spatial distributions of groundwater heads and flows, data on groundwater discharge into rivers and lakes as their joining with groundwater bodies. Appliance of the regional HM considerably improves the quality of the country’s sustainable water management, because HM provides consolidated knowledge on the interaction between surface water and groundwater and on their accessible resources. For solving practical problems of environmental protection and recovery, local HM are applied. They are created by completing the data of regional HM by more detailed information. In 2011–2015, scientists of Environment Modelling Centre (EMC) of Riga Technical University (RTU) developed four successive versions of the regional HM of Latvia: LAMO1→LAMO2→LAMO3→LAMO4. The current version LAMO4 has been tested and approbated in 2016–2018, by carrying out the research on nature processes on regional scale and also by using local HM. Presently, the information regarding the development and appliance of LAMO4 is available at the RTU EMC web site. In the near future, this information, as the set of geospatial data, will be inserted in the section “Hydrogeological data” of the portal “geolatvija.lv”. By using information provided by LAMO4 on the groundwater discharge in rivers, it will be possible to develop a computer model for the research of pollution processes in the river network of Latvia. In the future, the development of LAMO4→LAMO5→LAMO6 will considerably improve the credibility and quality of the data provided by modelling. For the next version LAMO5, the model set of lakes and rivers will be increased and the plane approximation step of 125 meters will be used (LAMO4 has the step of 250 meters). The version LAMO6 is the expansion of LAMO5 by adding information on groundwater quality and by providing advanced open data options. The research on LAMO development was supported by the European Regional Development Fund (2011–2012) and by the Latvian State Research Program “EVIDEnT” (2014–2018).

Zur Steigerung der Lagerlebensdauer von Hybridwälzlagern hat das Fraunhofer Institut für Produktionstechnologie IPT gemeinsam mit Cerobear GmbH, Hegenscheidt-MFD (A Member of the NSH-Group) und Schmitz-Metallographie GmbH an der Qualifizierung und Implementierung des Verfahrens Hartwalzen in die Prozesskette zur Herstellung von Hybridwälzlagern gearbeitet. Durch die Induzierung von Druckeigenspannungen in die Lagerlauffläche konnte die Lebensdauer nachweislich erhöht werden. Die Arbeiten wurden im Rahmen des geförderten Forschungsvorhabens „Hartwalzen von Lagerringen“ durchgeführt, das aus Mitteln des europäischen Fonds für regionale Entwicklung (EFRE) gefördert wurde.   To increase the service life of hybrid rolling bearings, the Fraunhofer Institute for Production Technology IPT together with Cerobear GmbH, Hegenscheidt-MFD (A Member of the NSH Group) and Schmitz-Metallographie GmbH successfully qualified and implemented the hard rolling process in the process chain for manufacturing hybrid rolling bearings. By inducing residual compressive stresses in the bearing running surface, the service life has been demonstrably increased. The work was carried out as part of the funded research project „Hard Rolling of Bearing Rings“, which was supported by the European Regional Development Fund (EFRE).

- The article describes the different stages which marked the elaboration of the EEC regional policy starting from the preliminary studies in the Sixties to the formal inclusion of this domain in the Single European Act (1986). The creation of the European Regional Development Fund (1975) and its reforms are crucial events in the definition of the EEC regional policy which highlight the slow and difficult passage from a system redistributing money among Member States to the launch of new form of supranational territorial solidarity. The ERDF, that was initially linked to the need to rearrange the financial benefits of membership/accession to the EEC for some members States (in particular, Italy and Great Britain), was later rearranged in order to allow more autonomous policy choices at the Community level (Community programmes). The Integrated Mediterranean Programmes, adopted in the Eighties, are the symbol of this new approach because they linked EEC regional measures to common problems arising from economic integration and increased the coordinating functions of the Commission.Parole chiave: Politica regionale della CEE, Commissione europea, Economie regionali, FESR, Programmi comunitari, PIM EEC Regional Policy; European Commission, Regional Economies, European Regional Development Fund, Community Programmes, Integrated Mediterranean Programmes

This article examines the transformation of the European Economic Community's (EEC) regional policy paradigms from the early 1970s, when negotiations for the creation of the European Regional Development Fund (ERDF) began, until the approval of the Single European Act. The article identifies this period as the beginning of a deep transition from demand-side "interventionist" and "neo-mercantilist" models — typical of certain regional policies used up to that time by member states (primarily by Italy) — towards more openly neoliberal models. My analysis of the harsh conflicts within the Regional Policy Committee (the national technocracies' representative body in charge of managing the ERDF) and between the committee and the European Commission demonstrate that this outcome was not at all taken for granted. It was determined, above all, by the overload of objectives of EEC regional policy in a context of scarce resources, and by the progressive lack of trust in the role of public intervention.
