description: This study aimed to develop valsartan (VAL)-loaded mixed micelles and investigate their cardioprotective potential and molecular mechanisms through Mhrt/Nrf2 and Trx1 pathways. VAL-loaded mixed micelles have not been elaborated and their impact on Mhrt/Nrf2 and Trx1 pathways has not been yet inspected. VAL-loaded mixed micelles were prepared, incorporating Pluronic F127 and Tween 80, adopting thin-film hydration method. The micelles were evaluated for drug entrapment efficiency, loading characteristics, particle size, morphology, in vitro drug release and micelles storage stability. The pharmacokinetic studies were explored in rats. Also, VAL suspension and mixed micelles were tested in cisplatin-induced cardiotoxicity in rats either pre to or simultaneously with cisplatin. RNA expression of lnc Mhrt and protein expression of Nrf2, Trx1, Ask1, AMPK and caspase 3, oxidative stress and cardiac injury markers besides tailed DNA% by comet assay were assessed. Pharmacokinetic studies evoked a 3.75-fold increase in oral bioavailability as compared with VAL suspension. Overall, treatment with VAL-loaded mixed micelles was superior to VAL suspension in decreasing oxidative stress and cardiac injury markers and restoring the abnormalities occurred in Mhrt/Nrf2 and Trx1 pathways. Thus, mixed micelles would be promising nanocarrier for the engineering of VAL with reinforced pharmacokinetics and cardioprotection characteristics.

description: We prove that any noetherian quasi-excellent scheme of characteristic zero admits a strong desingularization which is functorial with respect to all regular morphisms. We show that as an easy formal consequence of this result one obtains strong functorial desingularization for many other spaces of characteristic zero including quasi-excellent stacks and formal schemes, and complex and non-archimedean analytic spaces. Moreover, these functors easily generalize to non-compact setting by use of converging blow up hyper-sequences with regular centers.

description: In this paper, we design novel interactive deep learning methods to improve semantic interactions in visual analytics applications. The ability of semantic interaction to infer analysts' precise intents during sensemaking is dependent on the quality of the underlying data representation. We propose the $\text{DeepSI}_{\text{finetune}}$ framework that integrates deep learning into the human-in-the-loop interactive sensemaking pipeline, with two important properties. First, deep learning extracts meaningful representations from raw data, which improves semantic interaction inference. Second, semantic interactions are exploited to fine-tune the deep learning representations, which then further improves semantic interaction inference. This feedback loop between human interaction and deep learning enables efficient learning of user- and task-specific representations. To evaluate the advantage of embedding the deep learning within the semantic interaction loop, we compare $\text{DeepSI}_{\text{finetune}}$ against a state-of-the-art but more basic use of deep learning as only a feature extractor pre-processed outside of the interactive loop. Results of two complementary studies, a human-centered qualitative case study and an algorithm-centered simulation-based quantitative experiment, show that $\text{DeepSI}_{\text{finetune}}$ more accurately captures users' complex mental models with fewer interactions.

description: Fifty-two cases of monomorphic post-transplant lymphoproliferative disorders (M-PTLD), developed in patients undergone solid organ or bone marrow transplantation, were studied by the application of the tissue micro-array (TMA) technology. They included 50 cases of diffuse large B-cell lymphomas (DLBCL) and 2 Burkitt lymphomas (BL). In order to evaluate the immune-profile a large panel of antibodies was applied including several new markers (Cyclin D2, Cyclin D3, p27, PKC-β, FOXP-1 and Survivin) identified as negative prognostic factors in DLBCL of the immunocompetent patient. Out of 50 DLBCL, 23 cases (46%) had an Activated B Cell (ABC) phenotype,  8 (16%) a Germinal Centre B-cell (GCB) phenotype, and 11 (22%) an Unclassified (UC) phenotype. In 8 cases (16%) the subtype was not demonstrable due to sub-optimal preservation or loss of the tissue core. FISH analysis detected BCL2 gene amplification and MYC rearrangement. EBV was identified in 32 cases (64%) performing immunohistochemistry (LMP-1) and in situ hybridization (EBER). Clinical data and follow-up were available in all cases of malignant lymphomas but one. Thirty-two patients died for progression of disease or complications related to transplant (bleeding, bacterial infections, and multi-organ failure); 17 patients are actually alive and disease-free.
M-PTLD are aggressive lymphomas characterized by very poor outcome. The neoplastic process is stimulated by a prolonged immunosuppressive status which is capable to induce alterations of the immune system and allow EBV reactivation in previously infected patients. Indeed EBV infection seems to be the most significant risk factor to predict the development of a PTLD while age, sex, site of involvement and type of transplant do not have significant correlation. Furthermore DLBCL arisen in a setting of immunodeficiency share phenotypic and molecular features with DLBCL of the immunocompetent patient. In particular, the former shows a high incidence of BCL2 gene amplification and this aberration typically correlates with “non-GCB” phenotype. Also M-PTLD do express prognostic markers (PKC-β, cyclin D2, FOXP-1, and Survivin): notably, in our study, PKC-β and FOXP-1 were frequently expressed and they were predictive of a shorter overall survival even in lymphomas recognized to have a good prognosis (GCB-type). Given the fact that such molecules are detectable at the time of the diagnosis, we postulate whether a “tailored” or more specific therapy might be applied in the management of the immune-compromised patient.

description: During recent years a consistent number of central nervous system (CNS) drugs have been approved and introduced on the market for the treatment of many psychiatric and neurological disorders, including psychosis, depression, Parkinson disease and epilepsy. Despite the great advancements obtained in the treatment of CNS diseases/disorders, partial response to therapy or treatment failure are frequent, at least in part due to poor compliance, but also genetic variability in the metabolism of psychotropic agents or polypharmacy, which may lead to sub-therapeutic or toxic plasma levels of the drugs, and finally inefficacy of the treatment or adverse/toxic effects. With the aim of improving the treatment, reducing toxic/side effects and patient hospitalisation, Therapeutic Drug Monitoring (TDM) is certainly useful, allowing for a personalisation of the therapy. Reliable analytical methods are required to determine the plasma levels of psychotropic drugs, which are often present at low concentrations (tens or hundreds of nanograms per millilitre). 
The present PhD Thesis has focused on the development of analytical methods for the determination of CNS drugs in biological fluids, including antidepressants (sertraline and duloxetine), antipsychotics (aripiprazole), antiepileptics (vigabatrin and topiramate) and antiparkinsons (pramipexole). Innovative methods based on liquid chromatography or capillary electrophoresis coupled to diode-array or laser-induced fluorescence detectors have been developed, together with the suitable sample pre-treatment for interference removal and fluorescent labelling in case of LIF detection. All methods have been validated according to official guidelines and applied to the analysis of real samples obtained from patients, resulting suitable for the TDM of psychotropic drugs.

description: This work tries to find out thick brane solutions in braneworld scenarios described by a real scalar field in the presence of a scalar-kinetic term $F(X,ϕ)=Xϕ^m$ with a single extra dimension, where $X=\frac12\nabla_Mϕ\nabla^Mϕ$ stands for the standard kinetic term and $m=0,1,2\cdots$. We mainly consider bent branes, namely de Sitter and Anti-de Sitter four-dimensional slices. The solutions of a flat brane are obtained when taking the four-dimensional cosmological constant $Λ_4\rightarrow 0$. When the parameter $m=0$, these solutions turn to those of the standard scenario. The localization and spectrum of graviton on these branes are also analyzed.

description: We discuss Dyson's argument that the vacuum is unstable under a change g^2 -> - g^2, in the context of lattice gauge theory. For compact gauge groups, the partition function is well defined at negative g^2, but the average plaquette P has a discontinuity when g^2 changes sign. This reflects a change of vacuum rather than a loss of vacuum. In addition, P has poles in the complex g^2 plane, located at the complex zeros of the partition function (Fisher's zeros). We discuss the relevance of these singularities for lattice perturbation theory. We present new methods to locate Fisher's zeros using numerical values for the density of state in SU(2) and U(1) pure gauge theory. We briefly discuss similar issues for O(N) nonlinear sigma models where the local integrals are also over compact spaces.

description: As novas tecnologias para edição, tratamento e manipulação das imagens inauguraram instigantes possibilidades para a expressão artística em vários campos. Contudo, as novas mídias ao se depararem com estas possibilidades na miríade de imagens circulando a internet, abriu um campo de disputa pela realidade, uma guerra imagética para discernir o que é falso e verdadeiro, o que é real e o é que ficção. A crise de desinformação e proliferação de fake news tornou-se o novo status quo. Na produção do próprio pesquisador-artista, tem-se projetos que trabalham com manipulação de fotografias pessoais e históricas e suas narrativas inerentes. Assim, este artigo busca analisar a partir destas obras caminhos de diálogo na arte contemporânea com esta disputa pela realidade nas imagens e o jogo de percepção e adaptação do público a esta crise cultural.

description: Various satellite-borne missions are being planned whose goal is to measure the polarization of a large number of gamma-ray bursts (GRBs). We show that the polarization pattern predicted by current models of GRB emission can be drastically modified by the existence of very light axion-like particles (ALPs), which are present in many extensions of the Standard Model of particle physics. Basically, the propagation of photons emitted by a GRB through cosmic magnetic fields with a domain-like structure induces photon-ALP mixing, which is expected to produce a strong modification of the original photon polarization. Because of the random orientation of the magnetic field in each domain, this effect strongly depends on the orientation of the photon line of sight. As a consequence, photon-ALP conversion considerably broadens the original polarization distribution. Searching for such a peculiar feature through future high-statistics polarimetric measurements is therefore a new opportunity to discover very light ALPs.

description: The article continues the authors’ research in the field of building systems for automatic diagnostics conditions and dynamics of plant growth. New concepts of intelligent farming, where field conditions are controlled by autonomous systems, have now become widely used. Building such systems requires solving several problems related to digital image processing, such as detecting plants and identifying their condition. Therefore, the article studies the actual problem of constructing an automatic system for assessing the state and dynamics of plant growth. As the central component of the system under consideration, the authors propose to use the mathematical apparatus of convolutional neural networks. The article describes the architecture, training procedure, and testing of the neural network. The results of computer experiments are presented. The analysis of the work of convolutional neural networks shows the high efficiency of the proposed solution to the problem of assessing the state and growth dynamics of biological crops.
Plant associations within the subalpine mountain hemlock zone as indicators of recreational land use capability
Creators: name: Eekman, Gordon Clifford Duncan
Publisher: name: University of British Columbia
Year: 2010

description: This thesis is concerned with plant associations within the Subalpine Mountain Hemlock Zone as indicators of recreational land use capability. With the field recognition of approximately twenty plants (trees, tall shrubs, low shrubs, and ground plants) all the plant associations within this zone can be identified. Knowing the biogeoclimatic characteristics of the plant associations and the limitations of land for recreation, land use decisions concerning summer recreation can be made. The objectives are to develop criteria for rating the limitation of land for selected recreational activities; to summarize information about the plant associations and biogeoclimatic conditions found within the Subalpine Mountain Hemlock Zone of southwestern British Columbia for planning purposes; to assign capability ratings to land based on the biogeoclimatic characteristics of the plant associations and on the criteria for rating the limitation of land for recreational activities; and to illustrate how the capability ratings of plant associations for recreation can be used in recreation planning. This study is a response to the need for a simple, rapid, accurate, inexpensive, site specific approach to land use planning based on readily recognizable indicators. By identifying and mapping plant associations, a recreational land use capability distribution is made apparent. With such detailed site specificity, planners and natural resource managers can make rational decisions about land use based on the biogeoclimatic characteristics of plant associations and on the limitations of land for recreational activities. It is suggested that the land use planning approach presented in this thesis can be extended not only to other biogeoclimatic zones besides the Subalpine Mountain Hemlock Zone but also to other activities besides recreation.

description: The doctorate’s theme of research - Abstract
My doctorate’s theme of research is about the Investigation in the Italian criminal
proceedings.
The Italian Code of criminal procedure of 1988 is the fruit of a new ideology that
marks a departure from Italy’s prior inquisitorial tradition.
According to criminal procedure Code of 1988, an accusatorial system separates the
investigation and trial stages and the judge’s decision is based only on evidence
collected in oral form in his presence in a public trial containing adversarial
dynamics.
The Italian Code of 1988 created a separation between criminal investigations and
trial. Investigations are conducted by Public Prosecutor: he conducts the investigation
phase in order to deem whether to file a formal charge against the defendant or to
dismiss the case and the investigative evidence collected should serve only for this
purpose.
According to so called “inutilizzabilità fisiologica”’s rule, the evidence collected
during investigations by prosecutor is not usable during trial by the judge: the results
of the investigative efforts displayed by the parties should be kept outside of court. If
the proceedings go on to trial, the case shall be deemed with only evidence collected
in front of the judge.
To create the separation of the trial phase from the investigation stage, there is the
double-dossier system. During the investigations, evidence are collected in an
investigation dossier. The trial judge will never see the investigation dossier and the
trial judge’s decision is based on a new dossier, the trial dossier, with the evidence
collected during the trial.
The issue of my research is about the investigation, the so called “inutilizzabilità
fisiologica”’s rule and also the exclusionary rules that concern the investigative phase
and the decisions pronounced during the investigations (for example, the decisions
concerning pre-trial confinement).
2
In fact, the exclusionary rule system (so called “inutilizzabilità patologica”) provides
that evidence cannot be used in Italian criminal proceedings if it was the result of
illegal inquiry.
On the convexity of optimal control problems involving non-linear PDEs or VIs and applications to Nash games (changed title: Vector-valued convexity of solution operators with application to optimal control problems)

description: Generalized Nash equilibrium problems in function spaces involving PDEs are considered. One of the central issues arising in this context is the question of existence, which requires the topological characterization of the set of minimizers for each player of the associated Nash game. In this paper, we propose conditions on the operator and the functional that guarantee the reduced formulation to be a convex minimization problem. Subsequently, we generalize results of convex analysis to derive optimality systems also for non-smooth operators. Our theoretical findings are illustrated by examples.

description: The diffusion and low vibrational motions of adsorbates on surfaces can be well described by a purely stochastic model, the so-called interacting single adsorbate model, for low-moderate coverages (θ\lesssim 0.12). Within this model, the effects of thermal surface phonons and adsorbate-adsorbate collisions are accounted for by two uncorrelated noise functions which arise in a natural way from a two-bath model based on a generalization of the one-bath Caldeira-Leggett Hamiltonian. As an illustration, the model is applied to the diffusion of Na atoms on a Cu(001) surface with different coverages.

Stochastic geometric mechanics for geophysical fluid dynamics and wave-current interactions
Creators: name: Hu, Ruiao
Publisher: name: Imperial College London
Year: 2023

description: Geometric mechanics is a framework for the derivation and analysis of dynamical systems based on the Lie group transformation properties of the variational principles from which they arise. For example, geometric mechanics preserves the properties of energy conservation, Kelvin-Noether circulation dynamics, and the conservation laws resulting from the particle relabelling symmetry of ideal geophysical fluid dynamics (GFD). GFD models of real-world dynamics such as climate change involve interactions among disparate scales in space and time whose approximate modelling can introduce uncertainty. To meet this type of challenge, this thesis focuses on developing modelling schemes for introducing noise and coupling among multiscale multiphysics dynamics within the geometric mechanics framework. First, we develop a structure-preserving stochastic perturbation framework known as the Stochastic Forcing by Lie Transport (SFLT) using the reduced Lagrange-d'Alembert Pontryagin principle from geometric mechanics. When applied to GFD, SFLT preserves the conservation of energy and modifies the Kelvin-Noether circulation dynamics. Physically, the stochastic forces introduced by SFLT encompass stochastic variants of Craik-Leibovich forces and material entrainment effects. The Eulerian Average SFLT (EA SFLT) framework is also proposed as a modification of the SFLT framework where one replaces the fluid momentum and advected quantities with their expectations over the underlying probability space. Then, we formulate a class of wave-current interaction systems where the wave dynamics are assumed to be symmetry-breaking features of the current. The resulting equation contains the wave momentum, which links the tangled and untangled Poisson structure of the system. We show that this modelling approach is flexible enough to readily incorporate the stochastic perturbation frameworks of both SALT (Stochastic Transport by Lie Transport) and SFLT (Stochastic Forcing by Lie Transport). Lastly, we exemplify the wave-current interaction modelling approach by constructing three two-dimensional models to study satellite imagery of the ocean.

Deep geometry of subduction below the Andean

description: In this study new tomographic models of Colombia were calculated. I used the seismicity recorded by
the Colombian seismic network during the period 2006-2009. In this time period, the improvement of
the seismic network yields more stable hypocentral results with respect to older data set and allows to
compute new 3D Vp and Vp/Vs models. The final dataset consists of 10813 P- and 8614 S-arrival
times associated to 1405 earthquakes. Tests with synthetic data and resolution analysis indicate that
velocity models are well constrained in central, western and southwestern Colombia to a depth of 160
km; the resolution is poor in the northern Colombia and close to Venezuela due to a lack of seismic
stations and seismicity.
The tomographic models and the relocated seismicity indicate the existence of E-SE subducting Nazca
lithosphere beneath central and southern Colombia. The North-South changes in Wadati-Benioff zone,
Vp & Vp/Vs pattern and volcanism, show that the downgoing plate is segmented by slab tears E-W
directed, suggesting the presence of three sectors. Earthquakes in the northernmost sector represent
most of the Colombian seimicity and concentrated on 100-170 km depth interval, beneath the Eastern
Cordillera. Here a massive dehydration is inferred, resulting from a delay in the eclogitization of a
thickened oceanic crust in a flat-subduction geometry. In this sector a cluster of intermediate-depth
seismicity (Bucaramanga Nest) is present beneath the elbow of the Eastern Cordillera, interpreted as
the result of massive and highly localized dehydration phenomenon caused by a hyper-hydrous oceanic
crust. The central and southern sectors, although different in Vp pattern show, conversely, a continuous,
steep and more homogeneous Wadati-Benioff zone with overlying volcanic areas. Here a "normalthickened"
oceanic crust is inferred, allowing for a gradual and continuous metamorphic reactions to
take place with depth, enabling the fluid migration towards the mantle wedge.

description: Charmless charged two-body B decays are sensitive probes of the CKM matrix, that parameterize CP violation in the Standard Model (SM), and have the potential to reveal the presence of New Physics. The framework of CP violation within the SM, the role of the CKM matrix, with its basic formalism, and the current experimental status are presented. The theoretical tools commonly used to deal with hadronic B decays and an overview of the phenomenology of charmless two-body B decays are outlined. LHCb is one of the four main experiments operating at the Large Hadron Collider (LHC), devoted to the measurement of CP violation and rare decays of charm and beauty hadrons. The LHCb detector is described, focusing on the technologies adopted for each sub-detector and summarizing their performances. The status-of-the-art of the LHCb measurements with charmless two-body B decays is then presented. Using the 37/pb of integrated luminosity collected at sqrt(s) = 7 TeV by LHCb during 2010, the direct CP asymmetries ACP(B0 -> Kpi) = −0.074 +/- 0.033 +/- 0.008 and ACP(Bs -> piK) = 0.15 +/- 0.19 +/- 0.02 are measured.
Using 320/pb of integrated luminosity collected during 2011 these measurements are updated to ACP(B0 -> Kpi) = −0.088 +/- 0.011 +/- 0.008 and ACP(Bs -> piK) = 0.27 +/- 0.08 +/- 0.02. In addition, the branching ratios BR(B0 -> K+K-) = (0.13+0.06-0.05 +/- 0.07) x 10^-6 and  BR(Bs -> pi+pi-) = (0.98+0.23-0.19 +/- 0.11) x 10^-6 are measured.
Finally, using a sample of 370/pb of integrated luminosity collected during 2011, the relative branching ratios BR(B0 -> pi+pi-)/BR(B0 -> Kpi) = 0.262 +/- 0.009 +/- 0.017, (fs/fd)BR(Bs -> K+K-)/BR(B0 -> Kpi)=0.316 +/- 0.009 +/- 0.019, (fs/fd)BR(Bs -> piK)/BR(B0 -> Kpi) = 0.074 +/- 0.006 +/- 0.006 and BR(Lambda_b -> ppi)/BR(Lambda_b -> pK)=0.86 +/- 0.08 +/- 0.05 are determined.

description: Biomedical analyses are becoming increasingly complex, with respect to both the type of the data to be produced and the procedures to be executed. This trend is expected to continue in the future. The development of information and protocol management systems that can sustain this challenge is therefore becoming an essential enabling factor for all actors in the field. The use of custom-built solutions that require the biology domain expert to acquire or procure software engineering expertise in the development of the laboratory infrastructure is not fully satisfactory because it incurs undesirable mutual knowledge dependencies between the two camps. We propose instead an infrastructure concept that enables the domain experts to express laboratory protocols using proper domain knowledge, free from the incidence and mediation of the software implementation artefacts. In the system that we propose this is made possible by basing the modelling language on an authoritative domain specific ontology and then using modern model-driven architecture technology to transform the user models in software artefacts ready for execution in a multi-agent based execution platform specialized for biomedical laboratories.

Electricity pricing and equity
Creators: name: Friesen, Robert Stewart
Publisher: name: University of British Columbia

description: Our society has become heavily dependent on inputs of energy. Recently, however, concern has been expressed that the future supply of energy will be inadequate to meet our demands. It seems that future supplies of energy will be available only at relatively high cost. Moreover, conscious public policy attempts to reduce consumption may be attempted by raising the price of energy. A problem arises in the equitable distribution of our energy resources. To understand the equity issue and the price elasticity of demand question, a study was undertaken of the patterns of electricity consumption among residential consumers in Vancouver. The hypotheses proposed are that the proportion of income devoted to electricity consumption declines as income increases; the demand for electricity is price elastic; and, the ability to reduce electricity consumption increases with income. The methodology used to study these questions involved two steps. Firstly, a questionnaire was administered to 291 Vancouver households to identify variables potentially significant in determining, residential electricity consumption. Questions were also asked to determine perceptions of the ability or willingness to reduce or increase electricity consumption patterns under various hypothetical price intervention policies. Secondly, electricity consumption histories were obtained from B.C. Hydro and Power Authority for these 291 respondents. The study shows that absolute electricity consumption is not significantly affected by income. Hence, the proportion of income devoted to electricity declines as income increases. Secondly, it was found that the demand for electricity is sensitive to price increases, but not to price decreases. Thirdly, low income consumers are less responsive to price increases in electricity. They are less willing/able to switch from electricity to natural gas as a fuel source, and are less willing/ able to reduce electricity consumption levels when the price is increased. The results indicate that across the board price increases in electricity will bear very heavily on the poor. Various price schemes were examined with respect to their implications for equity, allocative efficiency and environmental quality. The preferred scheme sets allocative efficiency and environmental quality as constraints. Included in the package is a redistribution of income to achieve equity. The second best alternatives are pricing based on income and increasing block pricing.

description: Explanations in conventional recommender systems have demonstrated benefits in helping the user understand the rationality of the recommendations and improving the system's efficiency, transparency, and trustworthiness. In the conversational environment, multiple contextualized explanations need to be generated, which poses further challenges for explanations. To better measure explainability in conversational recommender systems (CRS), we propose ten evaluation perspectives based on concepts from conventional recommender systems together with the characteristics of CRS. We assess five existing CRS benchmark datasets using these metrics and observe the necessity of improving the explanation quality of CRS. To achieve this, we conduct manual and automatic approaches to extend these dialogues and construct a new CRS dataset, namely Explainable Recommendation Dialogues (E-ReDial). It includes 756 dialogues with over 2,000 high-quality rewritten explanations. We compare two baseline approaches to perform explanation generation based on E-ReDial. Experimental results suggest that models trained on E-ReDial can significantly improve explainability while introducing knowledge into the models can further improve the performance. GPT-3 in the in-context learning setting can generate more realistic and diverse movie descriptions. In contrast, T5 training on E-ReDial can better generate clear reasons for recommendations based on user preferences. E-ReDial is available at https://github.com/Superbooming/E-ReDial.

description: The abandonment of less productive fields and agro-forest activities has occured in the last decades, interesting large mountain areas in all mediterranean basin. Until the fifties, agricultural practices dealt mainly with soil surface and surface runoff control systems. However, the apparent sustainability of soil use results often in contrast with historical documents, witnessing heavy hydrogeological instability, in naturally fragile areas. The research focused on the dynamics and effects of post-coltural land abandonment in a critical mountain area of the Reno River. The Reno River rappresents a typical Tuscan-Emilian Apennines Watershed where soil erosion occurs under very different conditions depending on interactions between land use, climate, geomorphology and lithology. Landslides are largely  rappresented, due to the diffusion of clay hill slopes. Recent researches suggest that climatic variability will increase as a consequence of global climate change, resulting in greater frequency and intensity of extreme weather events, which could increase rates of erosion, landslides reactivations and diffusion of calanchive basins. As far as hill slopes are concerned, instability is today basically due to intrinsic factors, as the Apennine range is a rather young formation, in geological terms, and is mainly formed by sedimentary rocks with high occurrence of clays. Therefore landslides and rockfalls are very frequent, while surface soil erosion is generally low and anyway concentrated in the low Apennine, where intensive farming is still economically worth. The study, supported by GIS use, analyses the main fisical characteristics of the area and the historical changes of land use, and focalizes the dynamics of spontaneous reafforestation. Futhermore, the research studies the results of soil bioengineering and surface water control solutions for the restablishment of landslides occured in the last period.  Infact soil bioengineering has been recently used in different situations in order to consolidate slopes and hillsides and prevent erosion; when applied, it gave good results, both in terms of engineering efficiency and vegetational development, expecially if combined with a good hydraulic control, thus proving to be an actual alternative to other techniques with heavier environmental impacts. Research into the specific site features and the use of proper plant species is vital to the success of bioengineering works.

description: This article contains an investigation of the equitable basis for the Lie algebra sl_2. Denoting this basis by {x,y,z}, we have [x,y] = 2x + 2y, [y,z] = 2y + 2z, [z, x] = 2z + 2x. One focus of our study is the group of automorphisms G generated by exp(ad x*), exp(ad y*), exp(ad z*), where {x*,y*,z*} is the basis for sl_2 dual to {x,y,z} with respect to the trace form (u,v) = tr(uv). We show that G is isomorphic to the modular group PSL_2(Z). Another focus of our investigation is the lattice L=Zx+Zy+Zz. We prove that the orbit G(x) equals {u in L |(u,u)=2}. We determine the precise relationship between (i) the group G, (ii) the group of automorphisms for sl_2 that preserve L, (iii) the group of automorphisms and antiautomorphisms for sl_2 that preserve L, and (iv) the group of isometries for (,) that preserve L. We obtain analogous results for the lattice L* =Zx*+Zy*+Zz*. Relative to the equitable basis, the matrix of the trace form is a Cartan matrix of hyperbolic type; consequently,we identify the equitable basis with the set of simple roots of the corresponding Kac-Moody Lie algebra g. Then L is the root lattice for g and 1/2L* is the weight lattice, and G(x) coincides with the set of real roots for g. Using L, L*, and G, we give several descriptions of the isotropic roots for g and show that each isotropic root has multiplicity 1. We describe the finite-dimensional sl_2-modules from the point of view of the equitable basis. In the final section, we establish a connection between the Weyl group orbit of the fundamental weights of g and Pythagorean triples.
