Relativistic mass due to a dilatant vacuum leads to a quantum reformulation of the relativistic kinetic energy

Relativistic mass change with speed is considered as the effect of a viscous, dilatant vacuum, whose apparent viscosity is related to the Lorentz factor. Transient solidlike vacuum due to shear stress would be the reason why vacuum prevents the speed of massive objects from being indefinitely increased. Such a vacuum (that in a previous study allowed to exactly calculate the Pioneer anomaly, Mercury's perihelion precession and was shown to be compatible with stable planetary orbits) leads us here to a quantum formula for the relativistic kinetic energy. A formula which distinguishes between the case of accelerated charges in a vacuum, for which a Stokes-Einstein radius comes into play, and the case of accelerated macroscopic bodies, for which the quantum potential term vanishes. In this way, incidentally, one obtains again correct results for the Pioneer 10, confirming the role of vacuum's viscous force. This description of a quantum mechanism underlying the relativistic kinetic energy may be also helpful in constructing a theory of quantum relativity and might tell us more even about the interactions of matter with the Higgs field and the dark sector: two issues which can be themselves linked to a dilatant vacuum

Quantum gravity without gravitons in a superfluid quantum space.

This hypothesis starts from considering the physical vacuum as a superfluid quantum medium, that we call superfluid quantum space (SQS), close to the previous concepts of quantum vacuum, quantum foam, superfluid vacuum etc.[1, 2, 3] We usually believe that quantum vacuum is populated by an enormous amount of particles pairs (e.g. couples \mathrm{e^{-},\,e^{+}}) whose life is extremely short, in a continuous foaming of formation and annihilation. Here we move further and we hypothesize that these particles are superfluid symmetric vortices of space's quanta (SQ, for which we use the symbol \varsigma ), probably arising as perturbations of the SQS through a process similar to that of a Kármán vortex street. Because of superfluidity these vortices can have an indeterminately long life. Vorticity is interpreted as spin and if conflicting they cause destruction of the vortices, justifying matter-antimatter annihilation. SQS would be an ubiquitous superfluid sea of SQ, before being a foam of particles pairs. Due to its non-zero viscosity, these vortices attract the surrounding quanta, pressure decreases and the consequent incoming flow radially directed toward the center of the massive particle let arise a gravitational potential. This is called fluid quantum gravity, whose passive quantum is the SQ and the quantum potential is triggered by the spin of any massive particles. We don't need gravitons in this model. We immediately notice that such a fluid model perfectly matches Gauss's law for gravity and this has been indeed proven through CFD simulations. Once comparing fluid quantum gravity with general relativity, it is evident how a hydrodynamic gravity can fully account for the relativistic effects due to spacetime distortion, where the space curvature is substituted by flows of space's quanta in the SQS

Towards human-relevant preclinical models: fluid-dynamics and three-dimensionality as key elements

The activity of research of this thesis focuses on the relevance that appropriate in vitro fully humanized models replicating physiological microenvironments and cues (e.g., mechanical and fluidic) are essential for improving human biology knowledge and boosting new compound testing. In biomedical research, the high percentage of the low rate of successful translation from bench to bedside failure is often attributed to the inability of preclinical models in generating reliable results. Indeed, it is well known that 2D models are far from being representative of human complexity and, on the other side, although animal tests are currently required by regulatory organizations, they are commonly considered unpredictive. As a matter of fact, there is a growing awareness that 3D human tissue models and fluid-dynamic scenarios are better reproducers of the in vivo context. Therefore, during this PhD, I have worked to model and validate technologically advanced fluidic platforms, where to replicate biological processes in a systemic and dynamic environment to better assess the pharmacokinetics and the pharmacodynamics of drug candidates, by considering different case studies. First, skin absorption assays have been performed accordingly to the OECD Test Guidelines 428 comparing the standard diffusive chamber (Franz Diffusion Cell) to a novel fluidic commercially available organ on chip platform (MIVO), demonstrating the importance of emulating physiological fluid flows beneath the skin to obtain in vivo-like transdermal penetration kinetics. On the other hand, after an extensive research analysis of the currently available intestinal models, which resulted insufficient in reproducing chemicals and food absorption profiles in vivo, a mathematical model of the intestinal epithelium as a novel screening strategy has been developed. Moreover, since less than 8% of new anticancer drugs are successfully translated from preclinical to clinical trials, breast, and ovarian cancer, which are among the 5 most common causes of death in women, and neuroblastoma, which has one of the lowest survival rates of all pediatric cancers, have been considered. For each, I developed and optimized 3D ECM-like tumor models, then cultured them under fluid-dynamic conditions (previously predicted by CFD simulations) by adopting different (customized or commercially available) fluidic platforms that allowed to mimic u stimuli (fluid velocity and the fluid flow-induced shear stress) and investigate their impact on tumor cells viability and drug response. I provided evidence that such an approach is pivotal to clinically reproduce the complexity and dynamics of the cancer phenomenon (onset, progression, and metastasis) as well as to develop and validate traditional (i.e., platin-based drugs, caffein active molecule) or novel treatment strategies (i.e., hydroxyapatite nanoparticles, NK cells-based immunotherapies)

Dating the humans by radiocarbon

Radiocarbon has become a very powerful tool used for dating. This paper deals with a specific application of 14C, i.e. dating of humans. Attention is focused on those aspects that, if neglected, might lead to a misinterpretation of the results or to an unsatisfying accuracy of the measurement. After a brief description of the main principles on which the radiocarbon method is based and of Accelerator Mass Spectrometry, examples taken from the research activity of INFN-LABEC (Laboratorio di Tecniche Nucleari per i Beni Culturali) in Florence are presented. The case of the relics of St. Francis represents an example of dating not directly human remains but other objects that can be associated to them. The case of two burials from the archaeological area of Baratti-Populonia, in Tuscany, gives the possibility to show the importance of estimating the human palaeodiet when dating bone samples

Socio Economic Impact Assessment of Pre-harvest Sugarcane Burning: Empirical Data Around Wonji/Shoa and Matahara Sugar Factories

In Ethiopia, the area of sugarcane is rising rapidly in response to increased sugar demand for human consumption. Despite considerable diversity in production systems and contexts, sugarcane is particularly high impact crop with significant positive and negative environmental and socio economic influences. Depending on a systematic review of scientific evidence combined with data that was collected through household interviews, key informant interviews, focus group discussions, direct observation and field notes of the researcher as well as secondary data from various sources to complement the primary data, the present study assess the socio economic and environmental impacts resulting from pre-harvest burning of cane in Wonji/Shoa and Metahara sugarcane estates. The results of study Show that the pre-harvest  burning of cane harvesting practices have negative impacts on local economy in terms of human health (both local communities and sugarcane workers) resulting from smokes and dust particles. Moreover, the pre-harvest burning sugarcane practices have negative environmental effects as demonstrated by clearing of vegetation cover, depletion of water resources and soil degradation. On the other hand, sugarcane trash resources can be used for animals' feed and alternative energy sources like sugarcane briquette charcoal. Our findings then will help to guide sugar industries and policy makers with new insights/strategies in understanding the situated environmental and social impacts associated with alternative sugarcane harvesting system by using green harvesting technologies (either manual or mechanical) and at the same time opening job opportunity to the local communities by utilization of trash as animals feed, energy source and compost.  Finally, recommendations have been provided in order to address the socio-economic and environmental effects on local communities and sugarcane workers and air quality management.
