Dose-length-product determination on cone beam computed tomography through experimental measurements and dose-area-product conversion

The dosimetry of cone beam computed tomography (CBCT) is not fully elaborated yet, and some of these systems presents dose-area-product (DAP) values after an examination rather than, as in the case of traditional CT, the doselength- product (DLP). The purpose of this study was to provide a reproducible and straight-forward method for DLP measurements on CBCT, as well as to validate a tool for esti

Epilogue: The Barnahus Model : Potentials and Challenges in the Nordic Context and Beyond

A key message from this chapter - and the book as such - is that the Nordic Barnahus model is a step in the right direction in terms of meeting victimised children's needs and legal rights, and that it could be recommended as a promising practice for other countries. At the same time, it is not a quick fix. In light of the book contributions, this chapter discusses the potentials and challenges of

Extraction efficiency of four pesticides using the QuEChERS extraction method and analysis by HPLC/DAD

Att pesticider används som ett skydd i jordbruket är ingen nyhet, och är en nödvändighet för att skydda odlingarna från diverse insekter, ogräs och mögel. Jord är en komplex matris, och leder till olika upptagningsförmågor av just dessa besprutningar. Ett löpande problem är avsaknaden av instrument där halter av pesticider kan mätas med hög noggrannhet, även vid låga koncentrationer vid analys. MeA cleanup step is essential from an analytical perspective, to improve the chance of quantification and to minimize interference. Pesticides in soil are a necessity is agriculture for survival of crops and protection from unwanted growth and pests. However, an ongoing problem is the lack of instruments where levels of pesticides can be measured with high accuracy, even at low concentrations during

Investigating the Potential of an Integrated Coolant Waste Heat Recovery System in an HD Engine Using PPC Operation

With the increasing focus on reducing emissions and making fuel efficient vehicles within the automotive industry over the past few years, new methods are constantly being investigated to improve the efficiency of the powertrain. One such method is recovering waste heat from the exhaust gases as well as the coolant using a thermodynamic cycle such as a Rankine cycle. However, most studies looking
