The impact of a delivery project's business model in a project-based firm
Autor: Pertti Aaltonen, Sanna Mutka
Publikováno v: International Journal of Project Management. 31:166-176
If projects are independent business organizations having goals of their own instead of being direct subordinates to the parent firm, then project-level goals might contradict those of the parent firm. This raises an empirical question on the impact

That is not how we brought you up: how is the strategy of a project formed?
Autor: Pertti Aaltonen, Elisa Vuori, Sanna Mutka, Karlos Artto
PurposeThe requirements of various participants of a project may conflict with the strategy of the project's parent organization and, consequently, the project may form its individual strategy independently, to better align with the factors in its en

On-line monitoring for further corrosion reduction and better understanding of the activity build-up in LWR primary coolant systems
Autor: Kari Mäkelä, Pertti Aaltonen
Publikováno v: Mäkelä, K & Aaltonen, P 1993, '
monitoring for further corrosion reduction and better understanding of the activity build-up in LWR primary coolant systems ', International Journal of Pressure Vessels and Piping, vol. 55, no. 1, pp. 163-177 . https://doi.org/10.1016/0308-0161(93)90054-W
Uniform corrosion rates of materials in contact with the coolant in boiling water reactors (BWRs) and pressurized water reactors (PWRs) are low and this kind of material degradation is very unlikely to compromise the integrity of the primary pressure
