Denaturation mechanism of whey protein by using the hot extrusion technology
(2022-02)
Milk proteins are one of the heat-sensitive nutritional components, especially whey proteins changing their structure through thermal treatment, consequently denaturizing and aggregating. The transformation of native whey proteins structure in presence of shear stress resulted in the microparticulation, which affected the functional properties. Many authors investigated these parameters with different conditions; however, understanding the combination of relevant parameters of the microparticulation process of whey ...

A comparative study using water atomized and gas atomized powder in laser powder bed fusion process – Assessment of the fatigue performance
(2022)
Gas-atomized (GA, spherical) and water-atomized (WA, spattered) commercially pure iron (cp-Fe) powders were processed using laser-based powder bed fusion, resulting in a slightly higher porosity of the WA condition. In addition to characterization of quasi-static mechanical properties, fatigue tests, which are known to be detrimentally affected by porosity, were finally considered, revealing good properties even for the WA condition. In terms of microstructure stability, the GA and WA specimens significantly differ; ...

Functional characterization of disease-associated mutations in type I cGMP-dependent protein kinase
(2022-08)
Cardiovascular diseases are the leading cause of death worldwide, and while mainly associated with behavioral risk factors, they can also be linked to genetic disorders. The cGMP-dependent protein kinase type I (PKG I) plays a pivotal role in the homeostasis of the vasculature by mediating NO/cGMP-dependent relaxation of vascular smooth muscle cells. A recently described genetic risk factor associated with PKG I results in heritable thoracic aortic aneurysms and dissections (TAAD). Although PKG isoforms Iα and Iβ ...

Risk management and sustainability performance in circular supply chains
(2022-09)
This dissertation analyzes supply chain risk management (SCRM) and sustainability performance in the context of circular supply chains (CSCs). The implementation of circular economy (CE) thinking in firms and supply chains has a crucial role in fostering innovative and efficient ways of producing and consuming. However, CE implementation is not a straightforward process, begetting risks and uncertainties that can impact the overall sustainability performance of CSCs. Therefore, managers need to adopt appropriate ...

Neo-institutionalism and business sustainability in emerging economies
(2022)
This dissertation deals with the institutional environment surrounding the private sector in the various emerging markets and developing economies (EMDEs) worldwide where most of the global population lives. Its primary purpose is to identify and combine theoretical aspects of new (sociological) institutionalism/neo-institutionalism to better understand the role of institutional environments in shaping business impacts on sustainable development. Institutions shape the behaviour of individuals as well as entire groups ...
