Integrating Products, Processes, and Sourcing for Eco‐Innovation
Business Strategy and the Environment, EarlyView.ABSTRACT Eco‐innovation research has often examined regulatory or technological drivers but has paid limited attention to how long‐term organizational change shapes eco‐innovation in mature, resource‐intensive industries. This study addresses that gap by investigating how two leading Finnish pulp and paper firms integrated product, process, and ...

Geometric Analysis of an Integrated Pest Management Model Including Two State Impulses
Abstract and Applied Analysis, 2014 According to integrated pest management strategies, we construct and investigate the dynamics of a Holling-Tanner predator-prey system with state dependent impulsive effects by releasing natural enemies and spraying pesticide at different thresholds ...

Biotechnology Progress, EarlyView.Abstract Maintaining consistent quality in the manufacturing of biotherapeutic proteins in mammalian cell culture is challenging, with unplanned deviations causing inconsistencies and potential batch failure. Current methods for monitoring and controlling critical process parameters (CPPs) rely on slow, labor‐intensive offline analyses.

Criminal Behaviour and Mental Health, EarlyView.ABSTRACT Background Depression, anxiety and criminal behaviour are often correlated, but the direction and nature of these associations remain contested. Aims To investigate the temporal relationships between depression and/or anxiety and criminal behaviour at age 32 and depression and/or anxiety and criminal behaviour at age 48.

Electronic Journal of Differential Equations, 2013 We establish some oscillation criteria for a forced second-order differential equation with impulses. These results extend some well-known results for forced second-order impulsive differential equations with delay.

Mechanochemical Amidation Mediated by 1,1’‐Oxalyldiimidazole for the Synthesis of Agrochemicals
Chemistry – A European Journal, EarlyView.Mechanochemical amidation using 1,1'‐oxalyldiimidazole (ODI) overcomes limitations of 1,1’‐carbonyl diimidazole (CDI) as coupling agent by enabling the efficient mechanochemical synthesis of three marketed agrochemicals from deactivated carboxylic acids.

Practical Stability in terms of Two Measures for Impulsive Differential Equations with “Supremum”
International Journal of Differential Equations, 2011 The object of investigations is a system of impulsive differential equations with “supremum.” These equations are not widely studied yet, and at the same time they are adequate mathematical model of many real world processes in which the present state ...

Automated Process Optimization in a Novel Triple Shaft Mixer with Adaptive Mixing Modes
Chemie Ingenieur Technik, EarlyView.A novel multi‐purpose mixer with adjustable blade angle and a coaxial stirrer is developed, providing three degrees of freedom. An optimization strategy is integrated to autonomously identify optimal operating conditions through automated tests. The current draw of the main stirrer serves as the optimization criterion, while stirrer speeds, directions,
