Vertically Aligned Nanowires and Quantum Dots: Promises and Results in Light Energy Harvesting

2023

The synthesis of crystals with a high surface-to-volume ratio is essential for innovative, high-performance electronic devices and sensors. The easiest way to achieve this in integrated devices with electronic circuits is through the synthesis of high-aspect-ratio nanowires aligned vertically to the substrate surface. Such surface structuring is widely employed for the fabrication of photoanodes for solar cells, either combined with semiconducting quantum dots or metal halide perovskites. In this review, we focus on wet chemistry recipes for the growth of vertically aligned nanowires and technologies for their surface functionalization with quantum dots, highlighting the procedures that yie…

Estimation of wind velocity over a complex terrain using the Generalized Mapping Regressor

2010

Abstract Wind energy evaluation is an important goal in the conversion of energy systems to more environmentally friendly solutions. In this paper, we present a novel approach to wind speed spatial estimation on the isle of Sicily (Italy): an incremental self-organizing neural network (Generalized Mapping Regressor – GMR) is coupled with exploratory data analysis techniques in order to obtain a map of the spatial distribution of the average wind speed over the entire region. First, the topographic surface of the island was modelled using two different neural techniques and by exploiting the information extracted from a digital elevation model of the region. Then, GMR was used for automatic …

Il "linguaggio" della Corte costituzionale: note sparse su alcuni aspetti dell'esperienza recente

2023

Wittgenstein's theories offer the starting point for looking at the socio-political implications of the language spoken by the institutions in the various historical phases: the communication system with which they relate to the outside world is functional in conveying the sense and scope of their action, building a precise relationship with public opinion. Starting from this assumption, the contribution takes into consideration some aspects of the recent practice of the Constitutional Court, with particular regard to press releases, and proposes an interpretation of the communication breakthrough pursued in recent years, relating it to the exercise of the function of warranty.

Compression and load balancing for efficient sparse matrix-vector product on multicore processors and graphics processing units

2021

We contribute to the optimization of the sparse matrix-vector product by introducing a variant of the coordinate sparse matrix format that balances the workload distribution and compresses both the indexing arrays and the numerical information. Our approach is multi-platform, in the sense that the realizations for (general-purpose) multicore processors as well as graphics accelerators (GPUs) are built upon common principles, but differ in the implementation details, which are adapted to avoid thread divergence in the GPU case or maximize compression element-wise (i.e., for each matrix entry) for multicore architectures. Our evaluation on the two last generations of NVIDIA GPUs as well as In…

Teenage Violence Toward Parents – in Search of the Theoretical Bases of a Research Tool

2020

The article contains an analysis of results of the available research on the phenomenon of children’s violence toward their parents. The main purpose of this interpretation is to search for the theoretical structure of a prepared research tool, initially called the Teen Violence Scale Toward Parents (TVSTP). The subject of the analyzes were works and research reports as well as police statistics containing information on the phenomenon of domestic violence, including teenage violence toward parents. As a result of the analysis, the theoretical function of the proposed research tool was distinguished, referring to types of violence possible to diagnose within this area. The proposed tool was…

Zarządzanie funkcją środowiskową w rolnictwie - źródło nowych rent gospodarstw rolnych

2016

W Unii Europejskiej ekologizacja rolnictwa stanowi wstępny etap takiej jego transformacji, która umożliwi gospodarstwom rolnym, rozmieszczonym w różnych miejscach przestrzeni europejskiej, trwały udział w kreowaniu zielonego wzrostu. Praca jest próbą odpowiedzi na pytanie: Czy dzięki doskonaleniu zarządzania funkcją środowiskową towarowe gospodarstwa rolne regionu opolskiego mogą przygotować się do wyzwań związanych z gospodarką sieciową i zadań obecnego etapu ich modernizacji? W opracowaniu przedstawiono rolę polityki ekologicznej w definiowaniu obecnego etapu modernizacji gospodarstw rolnych, mechanizmy jej integracji z celami WPR do 2020 r. oraz strategią Europa 2020. Ustalenia te stanow…

Performances linguistiques des enseignants et qualité d'apprentissage des élèves au primaire

2011

In a broad sense Education for All (EFA) is a hazardous Issue for to the least developed countries, and yet it adds, almost always, for these countries to provide additional difficulty for initial learning periods when majority in pupils has to assume the route from the local language to the teaching one. Besides, adapting in this context the provision of education has often done under the financial constraint. The hiring for supplementary teachers, as to reach EFA goal, less paid in comparison to their older colleagues. So now the teacher staff is consequently represented by new teachers with fewer initial education and pedagogical training, but definitely closer to the communities. The re…

INFLUENCIA DE FACTORES FAMILIARES Y PERSONALES EN LA EVOLUCIÓN NEGATIVA DEL TDAH

2016

Abstract.INFLUENCE OF PERSONAL AND FAMILY FACTORS ON THE NEGATIVE COURSE OF ADHDObjective. To study the effect of the cumulative adversity on the course of ADHD symptoms, associated problems and dysfunctionality of ADHD children. Method. 61 families of children with a clinical diagnosis of ADHD combined subtype were evaluated on two different times (Time I: mean age = 8.7; Time II: mean age = 11). We developed a personal risk index (high levels of ADHD symptoms, high number of associated problems, presence of oppositionism, stressful child characteristics and family history of ADHD), a family risk index (presence of mothers’ psychopathology, high parental stress and dysfunctional discipline…

Conformational investigation of alpha,beta-dehydropeptides. IX. N-Acetyl-(E)-alpha,beta-methylamide: stereoelectronic properties from infrared and th…

1998

The Fourier transform infrared spectra of Ac-(E)-deltaAbu-NHMe were analyzed to determine the predominant solution conformation(s) of this (E)-alpha,beta-dehydropeptide-related compound and the electron density perturbation in its amide groups. The measurements were performed in dichloromethane and acetonitrile in the region of mode vs (N-H), amide I, amide II and vs (C(alpha)=Cbeta). The equilibrium geometrical parameters, calculated by a method based on the density functional theory with the B3LYP functional and the 6-31G* basis set, were used to support spectroscopic interpretation and gain some deeper insight into the molecule. The experimental and theoretical data were compared with th…
