Pollution due to natural radioactivity is still a poorly known topic among young people. This paper describes the contents for an introductive university course or lecture conceived in a multitask program. Along with a so-called “flipped” configuration, where students are able to receive didactic materials prior to face-to-face lessons, multimedia contents should be shown to the students, who are at first faced with known anthropogenic accidents. Moreover, field and laboratory experimental activities can provide further insight regarding the radiological assessment strategies. Here, the most important principles and effects concerning the radioactive decay of naturally occurring radionuclides are described. The greatest part of natural radioactivity derives from terrestrial radionuclides occurring in soil and rocks. The radionuclides are atoms characterized by an excess of nuclear energy, which makes them unstable giving rise to decay. The radionuclides emit gamma rays, as well as alpha and/or beta particles. People are constantly subjected to indoor and outdoor exposure due to natural radioactivity. The possible sources can be considered as external due to natural sources located outside the human body, and internal provoked by ingestion or inhalation of radionuclides. The indoor exposure from natural sources is mainly related to radiation from building materials and to radon entering buildings from soils and rocks though cracks in walls and floor. The outdoor exposure mainly accounts for the terrestrial gamma radiation that crosses the soil air interface, and for the radon emitted from soils in seismic and volcanic areas. In this regard, there is a strong relationship between health diseases (e.g. cancer, necrosis and DNA and RNA modifications) and high-levels of natural radioactivity. For this reason, the radiological assessment of the most vulnerable areas represents a key point in order to mitigate hazard and risk connected to the human exposure to natural radioactivity.

Abandoned mines and quarries represent sites with the request of restoration due to their pollution. On the other hand, biofuels represent a response to the present request of sustainable energy, in order to reduce the CO$_2$ emission, in transportation, but also in energy production and domestic use. However, biofuels production seldom requires lands for the biomass cultivation. In this paper, the use of the dismissed mines and quarries is suggested for the cultivation of algae, as biomass production. To support this approach, a theoretical numerical evaluation of a typical dismissed quarry is developed in order to highlight the feasibility of the approach itself.

F. A. Basile, M. Bonanzinga, N. Carlson, J. Porter
In this paper the investigation of n -H-closed spaces that was started by Basile et al . (2019) is continued for every n ∈ ω, n ≥ 2. In particular, starting with the relationship between the absolute space PX of an arbitrary topological space X , reported by Ponomarev and Shapiro (1976) and introduced by Blaszczyk (1975, 1977), Ul'yanov (1975a,b) and Shapiro (1976), it is shown that the absolute PX is n -H-closed if and only if X is n -H-closed. For an arbitrary space X , a β-like extension (β for the Stone-Cech compactification) Y is constructed for the semiregularization PX(s) of the absolute PX such that Y is a compact, extremally disconnected, completely regular (but not necessarily Hausdorff) extension of PX(s) , and PX(s) is C* -embedded in Y . The definition of the Fomin extension σ X for a Hausdorff space X (Porter and Woods 1988) is extended to an arbitrary space X and σ X X is shown to be homeomorphic to the remainder Y PX(s) . A similar result is established when X is an n -Hausdorff space defined by Basile et al. (2019). Further, we give a cardinality bound for any n -Hausdorff space X and show that the inequality |X| ≤ 2^χ( X ) for an H-closed space X proved by Dow and Porter (1982) can be extended to n -H-closed spaces.
本文研究了由Basile et al。（2019）对于每个n∈ω，n≥2是连续的。特别地，从Ponomarev和Shapiro（1976）报道并由Blaszczyk（19751977）、Ul’yanov（1975a，b）和Shapiro（1976）引入的任意拓扑空间X的绝对空间PX之间的关系开始，证明了绝对PX是n-H-闭的当且仅当X是n-H-闭合的。对于任意空间X，为绝对PX的半正则化PX（s）构造了一个β样扩展（Stone-Cech紧化的β）Y，使得Y是PX的一个紧的、极端不连通的、完全正则的（但不一定是Hausdorff）扩展，并且PX（s是C*-嵌入在Y中的。Hausdorff空间X的Fomin扩张σX的定义（Porter和Woods 1988）被推广到任意空间X，并且σXX被证明与余数YPX（s）同胚。当X是Basile等人定义的n-Hausdorff空间时，也建立了类似的结果。（2019）。此外，我们给出了任意n-Hausdorff空间X的基数界，并证明了由Dow和Porter（1982）证明的H-闭空间X的不等式|X|≤2^χ（X）可以推广到n-H-闭空间。

The Francesco Vitale Sicilian collection of Apionidae is critically revised. Hoplopodapion poupillieri (Wencker, 1864), Ischnopterapion (Ischnopterapion) aeneomicans nothum (Desbrochers des Loges, 1897) and Pseudoprotapion dumeei (A. Hoffmann, 1957) are recorded for the first time from Sicily and Italy; Omphalapion laevigatum (Paykull, 1792) is recorded for the first time from Sicily, whereas the presence on the island of Aizobius sedi (Germar, 1818) and Acentrotypus brunnipes (Boheman, 1839), until now considered doubtful, is confirmed. All species quoted from Sicily by Vitale are listed and commented. In addition, the previous citation of Ceratapion (Echinostroma) basicorne (Illiger, 1807) from Cyprus is attributed to Ceratapion (Echinostroma) curtii (Wagner, 1920) and C. curtii is recorded for the first time from this country. Brief comments on our current knowledge of the apionid fauna of Sicily are also included.

In this paper, exact and numerical solutions of two dimensional time-fractional diffusion-reaction equation involving the Riemann-Liouville derivative are determined, by applying a procedure that combines the Lie symmetry analysis with the numerical methods. Two new reduced fractional differential equations are obtained by using the Lie symmetry theory. Applying only one Lie transformation, we get a new time-fractional partial differential equation and, applying a further Lie transformation, we get an ordinary differential equation. Numerical solutions of the reduced differential equations are computed separately by implicit numerical methods. A comparative study between numerical solutions is performed.

Let n,k ∈ N , and let T > 0, Y ⊆ R n and ξ = (ξ 0 , ξ 1 ,..., ξ k -1 ) ∈ ( R n ) k . Given a function f :[0, T ]×( R n ) k × Y → R , we consider the Cauchy problem f ( t,u,u ′ ,..., u (k) ) = 0 in [0, T ], u (i) (0) = ξ i for every i = 0, 1,..., k −1. We prove an existence and qualitative result for the generalized solutions of the above problem. In particular, we prove that, under suitable assumptions, the solution set S T f ( ξ ) of the above problem is nonempty, and the multifunction ξ ∈ ( R n ) k → S T f ( ξ ) admits an upper semicontinuous multivalued selection, with nonempty, compact and connected values. The assumptions of our result do not require any kind of continuity for the function f (·,·, y ). In particular, a function f satisfying our assumptions could be discontinuous, with respect to the second variable, even at all points ξ ∈ ( R n ) k .

This paper develops a non-equilibrium thermodynamics approach to oncogenesis, with a particular focus on ‘symmetry breaking’. The Onsager phenomenological coefficients are introduced to show the biophysical and thermophysical properties of cellular systems with differences between normal and cancerous cells. Seebeck- and Peltier-like effects are introduced to simplify the description of heat exchange and ion fluxes, in an effort to characterize the distinct role of the cellular electric membrane potential. Our result indicate that oncogenesis leads to changes in: (i) the thermophysical properties of the cell cytoplasm, caused by differences in density and heat capacity, (ii) the interactions with the micro-environment, (iii) geometrical characteristics, both in fractal dimensions and in shape symmetry, and (iv) the constitutive properties of membrane fluxes. This presents a unifying biophysics concept for such diverse characteristics, and it may yield new diagnostic and therapeutic opportunities.

This paper compiles an updated checklist of the Sicilian Cassidinae and Cryptocephalini species (Coleoptera: Chrysomelidae, Cassidinae and Cryptocephalinae) starting from a critical bibliographic screening and adding new material, mainly collected by the first author in the last few decades. A total of 61 species is reported, with new data for many rarely collected taxa. The provided data expand the known distribution of many uncommon species in Sicily. Two species are recorded for the first time: Cassida inopinata Sassi and Borowiec, 2006 and Cryptocephalus (Cryptocephalus) bimaculatus Fabricius, 1781 and two uncertain presences are confirmed: Cassida deflorata Suffrian, 1844 and Cassida nobilis Linne, 1758. The presence of other sixteen species is considered questionable and needs further confirmation.
