Characterisation of the lactation curve of Gyr and Sardo Negro cattle
(2023-07)
The objectives were to characterize the lactation curves (LC) of tropical Gyr and Sardo Negro (SN) cattle from Mexico for the design of breeding and management programs for these breeds. A total of 3561 records of 504 lactations and 3927 records of 449 lactations were used for Gyr and SN, respectively. Three lactation lengths (LL) were evaluated, namely 240 (240d), 270 (270d), and 300 (300d) days, with five non-linear models (NLM): Wood, Wiltmink, Cobby, Brody, and Sikka. Milk production was obtained at the beginning ...

Industry 4.0-driven additive manufacturing for operations in the circular economy
(2023-06)
This dissertation focuses on exploring how key elements of Industry 4.0 (I4.0), such as additive manufacturing (AM) and quantitative techniques/simulation, instigate the operations of an organisation towards the circular economy (CE). AM represents the technological foundation of future manufacturing which efficiently utilises materials avoiding unnecessary waste. Further, it could positively impact the transition towards CE by addressing issues related to the operations and supply chains while positively influencing ...

Foreign Capital and Economic Development
(2023-07)
The Irish political economy is notable for the sustained and central role of foreign investment in driving economic growth, notably via the commercial activities of multinational corporations, and more recently financial services. Beginning in the 1950s, the Irish state began to move away from its protectionist policies of import-substituting industrialization, and transitioned towards a liberalized, export-led industrialization model of economic growth in order to achieve its developmental catch-up. This has resulted ...

Geospatial crop yield modeling for climate change risk transfer, impact assessment, and adaptation strategies
(2023)
Changing climate and weather patterns increase the pressure on food production systems worldwide, significantly impacting livelihoods and economies at various scales. Understanding and adapting/mitigating climate change are essential to cope with the adverse effects of climate change. Biophysical crop modeling offers a unique way to assess the pros and cons of different adaptation strategies because they integrate physical and biological principles to simulate the use and allocation of captured resources mechanistically. ...

Analysis of a Coupled Fluid-Elastic Interaction Problem
(2023-01)
In this thesis, a non-linear system of partial differential equations is studied, describing the motions of an elastic structure which is immersed into an incompressible viscous fluid. The displacement of the elastic structure is modelled by a Lamé system and the fluid velocity as well as the fluid pressure are described by the Navier-Stokes equations. The structure and the fluid are coupled via two boundary conditions at the interface which correspond to continuity of velocities and forces. As the elasticity is ...

Intervention options for small-scale family poultry development in south-eastern Madagascar: an expert survey
(2023-03-14)
The diets of resource-poor farmers in the Atsimo Atsinanana (AA) region of south-eastern Madagascar have limited diversity and are low in animal protein. Although poultry farming is widespread, productivity is low, and consumption of eggs is uncommon. To enable effective development interventions targeting poultry value chains, this study pursues two goals: (i) to describe current challenges in small-scale poultry rearing and egg consumption in AA, and (ii) to explore viable options for promoting poultry production. ...

Nutrition transition in Kyrgyzstan: Understanding the triple burden of malnutrition and the importance of dietary quality
(2023)
Nutrition transition, including changes in lifestyle and diet, has been taking place globally. Malnutrition is a serious public health issue responsible for the considerable portion of noncommunicable diseases (NCDs). Currently, little knowledge about nutrition transition and its relation to malnutrition exists in low and middle-income countries. Kyrgyzstan undergoes a nutrition transition with health and diet implications, especially to women. Kyrgyzstan is believed to be at the end of the ‘receding famine’ stage ...
