Family therapy as a model for treating childhood obesity: Useful tools for clinicians
- 2011

In: Clinical Child Psychology and Psychiatry. - : SAGE Publications. - 1359-1045 .- 1461-7021. ; 16:1, s. 129-145

- More than 15 percent of children in Europe are overweight; another 5 percent are obese. The high prevalence of obesity emphasizes the necessity of developing evidence-based treatment programs that are useful in a clinical setting. Management of childhood obesity is commonly based on lifestyle interventions where nutrition, physical activity, and behavior modification are the main targets. To incorporate lifestyle interventions, many childhood obesity treatment models use different psychological models, such as behavior modification or cognitive behavior therapy. This paper presents the key lessons from a research program on an empirically supported family-therapy-based treatment, Standardized Obesity Family Therapy (SOFT). SOFT is based on systemic and solution-focused theories and has shown positive effects on the child with respect to degree of obesity, physical fitness, self-esteem, and family functioning in several studies. The distinguishing features of SOFT are the focus on family interactions as an important source for implementing and maintaining lifestyle changes, the multidisciplinary team approach, and a limited number of sessions (three to four per year). The main aim of this paper is to provide tools for clinicians in the field of obesity who work with families, alone or in a multidisciplinary team.

Modeling of Reverse Flow Partial Oxidation Process for Gasifier Product Gas Upgrading
- 2010
-
In: Proceedings of the 5th International Conference on Thermal Engineering:Theory and Applications 2010. - 1894503937
-
Conference paper (peer-reviewed)abstract
- Biomass gasification is one of the alternatives to producing liquid fuels and chemicals from biomass residues. The gas produced in gasification contains CO, H2, H2O, CO2, light hydrocarbons and tars. Depending on the gasifier type, operating conditions and fuel, the light hydrocarbons can contain as much as 50 % of the total energy contents in the gas. The gas also contains catalyst poisons such as sulfur, as H2S and COS. This paper presents simulation work of a reverse flow partial oxidation reformer that reaches efficiencies approaching conventional catalytical processes. Furthermore, different reactor designs and parameter variations such as pressure are investigated. For comparison, natural gas simulations are included which clearly show the benefits of using reverse flow operation with lean gases such as gasifier product gas.

Role of alloy composition on the stability of nitrides in Ti-microalloyed steels during weld thermal cycles
- 1984
-
In: Metallurgical Transactions. A, Physical Metallurgy and Materials Science. - 0360-2133. ; 15:1, s. 33-41
-
Journal article (peer-reviewed)abstract
- The effect of cycling on titanium nitride stability in a range of normalized steels containing additions of V, Al, and N has been investigated. Nitride dispersions and chemical analysis of individual particles are studied using transmission electron microscopy and a quantitative 200 kV STEM-EDX-EELS microanalysis system. Whereas normalized material contains nitrides of mixed compositions, only nitrides based on TiN survive high energy simulated weld cycles. Grain growth is dependent on stability, and this depends on the original composition of the nitrides. The presence of aluminum is particularly detrimental. The best gain growth control and highest toughness are found in steels based on optimum ratios of Ti/V/N and on low Al levels

Discovery of two new supernovae and an AGN outburst by PS1
- 2010
-
Reports (other academic/artistic)abstract
- We report the discovery of two spectroscopically-confirmed Supernovae PS1-1000302 and PS1-1000303, and an AGN outburst PS1-1000305 in the Pan-STARRS1 "3Pi Faint galaxy supernova survey". PS1-1000302 was detected on June 12.4 UT (g=18.5) at 16:33:43.094 +54:42:04.18 (J2000) located 1.1" from the center of the host galaxy SDSS J163343.08+544205.4. PS1-1000303 was detected on June 14.3 UT (g=19.2) at 17:11:52.827 +43:36:57.06 (J2000) located 0.4" from the center of the host galaxy SDSS J171152.82+433656.7.

Compositional modeling of railway Virtual Coupling with Stochastic Activity Networks
- 2021
-
In: Formal Aspects of Computing. - : Springer. - 0934-5043 .- 1433-299X. ; 33, s. 989-1007

Journal article (peer-reviewed)abstract
- The current travel demand in railways requires the adoption of novel approaches and technologies in order to increase network capacity. Virtual Coupling is considered one of the most innovative solutions to increase railway capacity by drastically reducing train headway. The aim of this paper is to provide an approach to investigate the potential of Virtual Coupling in railways by composing stochastic activity networks model templates. The paper starts describing the Virtual Coupling paradigm with a focus on standard European railway traffic controllers. Based on stochastic activity network model templates, we provide an approach to perform quantitative evaluation of capacity increase in reference Virtual Coupling scenarios. The approach can be used to estimate system capacity over a modelled track portion, accounting for the scheduled service as well as possible failures. Due to its modularity, the approach can be extended towards the inclusion of safety model components. The contribution of this paper is a preliminary result of the PERFORMINGRAIL (PERformance-based Formal modelling and Optimal tRaffic Management for movING-block RAILway signalling) project funded by the European Shift2Rail Joint Undertaking.
