Applications of Forensic Entomology in death investigation.
No full textIn most investigation systems there is still a great uncertainty on the value of insects as forensic indicators. Even if the important role of insects in human decay is well known and documented in literature, maggots crawling on bodies are still considered just another disgusting element of decay; something to be rinsed away as soon as the body is placed on the autopsy table.
This skeptical behaviour of many pathologists and investigators, based mainly on the lack of knowledge of this discipline, is no more admissible. The entomological specimens must be considered a physical evidence as well blood stains, fingerprints, fibers or traces of other biological fluids and insects should be processed as evidence at the crime scene examination as well at the autopsy.
The major goal of medicocriminal entomology is to contribute to the determination of the time since death because insects feeding on corpses can represent a suitable biological clock eventually corresponding to the minimum Post Mortem Interval (PMI). Often, the assessment of death chronology on badly decomposed bodies or skeletonized remains can be only made based on insects due to lack of information usually provided by a classical post mortem changes in such corpses.
However, during the past decades the potential of forensic entomology has been largely documented by several case studies both in Europe and in USA. The techniques devised recently can allow expert in the field to collect strong entomological evidence and provide useful information in a death investigation not only on time since death but also on geographical location of death, time of dismemberment, submersion interval, inferences of trauma, post mortem artifacts, removal of remains, use of drugs cause and even more in linking a suspect to the scene of a crime, in child neglect, sexual molestations and identification of suspects.
This presentation will show briefly several case studies as examples of the application of forensic entomology in death investigation

No full textFinancial firms’ crisis and productivity analysis: a comprehensive approach
No full textThis book is an attempt to settle different perspectives to look at a
fundamental theme of management theory, since it was born: the survival
of firms. Starting with a first chapter that comments on the latest
regulatory measures at EU level, the work makes an excursus of the
scientific literature on the issue of the firms’ crisis, with a specific focus
on the quantitative methods available to measure this phenomenon.
The last chapter compares different analytical, econometric methodologies
applied to an existing case history - that of Italian companies -,
over a very long period of time. Furthermore, the authors propose a
combined methodology of productivity analysis and limited dependent
variables model that enriches the scientific debate by proposing quantitative
tools suitable for the developments of the EU discipline

Wake-tracking and turbulence modelling in computational aerodynamics of wind turbine aerofoils
No full textThis article addresses two modelling aspects of wind turbine aerofoil aerodyna-mics based on the solution of the Reynolds-averaged Navier–Stokes (RANS) equations. One of these is the effect of an a priori method for structured grid adaptation aimed at improving the wake resolution. The presented results emphasize that the proposed adaptation strategy greatly improves the wake resolution in the far field, whereas the wake is completely diffused by the non-adapted grid with the same number and spacing patterns of grid nodes. The proposed adaptation approach can be easily included in the structured generation process of both commercial and in-house-structured mesh generators.
The other numerical aspect examined herein is the impact of particular choices for turbulence modelling on the predicted solution. This includes the comparative analysis of numerical solutions obtained by using different turbulence models, and also aims at quantifying the solution inaccuracy arising from not modelling the laminar-to-turbulent transition. It is found that the drag forces obtained by considering the flow as transitional or fully turbulent may differ by 50 per cent.
All these issues are investigated using a special-purpose hyperbolic grid generator and two multi block structured finite volume RANS codes. The numerical experiments consider the flow field past a wind turbine aerofoil for which an exhaustive campaign of steady and unsteady experimental measurements was conducted. The predictive capabilities of the CFD solvers are validated by comparing experimental data and numerical predictions for selected flow regimes. The incompressible analysis and design code XFOIL is also used to support the findings of the comparative analysis of numerical RANS-based results and experimental data
