Let-7d miRNA Shows Both Antioncogenic and Oncogenic Functions in Osteosarcoma-Derived 3AB-OS Cancer Stem Cells
2015
Osteosarcoma (OS), an aggressive highly invasive and metastatic bone-malignancy, shows therapy resistance and recurrence, two features that likely depend on cancer stem cells (CSCs), which hold both self-renewing and malignant potential. So, effective anticancer therapies against OS should specifically target and destroy CSCs. We previously found that the let-7d microRNA was downregulated in the 3AB-OS-CSCs, derived from the human OS-MG63 cells. Here, we aimed to assess whether let-7d modulation affected tumorigenic and stemness properties of these OS-CSCs. We found that let-7d-overexpression reduced cell proliferation by decreasing CCND2 and E2F2 cell-cycle-activators and increasing p21 an…
Efficient H2 production by photocatalytic water splitting under UV or solar light over variously modified TiO2-based catalysts
2019
Abstract This paper focused for the first time on the comparison between three different approach to modify the chemico-physical properties of TiO2-based photocatalysts and their effect in the H2 production by photocatalytic water splitting both under UV and solar light irradiation, under the same experimental conditions. The application of pulsed laser irradiation to aqueous TiO2 suspensions (first approach) induced structural transformations both on the bulk and on the surface of TiO2, boosting the H2 production, under UV light irradiation, of almost three times (20.9 mmol/gcat·h) compared to bare TiO2 (7.7 mmol/gcat·h). The second strategy was based on a templating method to obtain TiO2 …
EFFECTS OF THE PENETRATION OF WIND POWER IN THE BRAZILIAN ELECTRICITY MARKET
2016
Climate variability has been the main driver for renewables in the Brazilian electricity market. This article analyzes the vulnerabilities of the dependence on hydropower in renewable energy production due to climate variation, as well as wind power penetration in Brazil, given a set of wind industry policies. Despite Brazilian renewable energy increase, the study shows the impact in energy supply in north region, due to the lack of transmission infrastructure. In Brazil, the potential trade-offs between renewables growth, and transmission infrastructure inconsistencies in terms of policy implementation are not yet well analyzed. Simulation results show the potential conflicts between energ…

Renewable sources and its applications awareness in educational institutions
2019
The topic of the presented research was to analyze the awareness on renewable energy sources among the students of three universities: the Ural Federal University (Russia), the University of Trento (Italy) and Lucian Blaga University of Sibiu (Romania). The survey included 6 basic multiple-choice questions about the main points of the renewable energy topic. Data were collected and analyzed in aid of percentage ratio of right answers among students on each possible answer. The approach adopted in the three universities for the education on topics related to renewable energy is different. This difference explains the different point of view of students on renewable energy.
Pique-niquer in Paris
2015
Una antica tradizione rinnova il rapporto tra Parigi e i suoi abitanti: l’uso sociale e pubblico di prati, giardini, scalinate, sponde dei canali e lungofiume per consumare, con estrema nonchalance, il rito del picnic. Pique-niquer è un verbo francese che abbina piquer (prendere, rubacchiare, spilluzzicare) con nique (piccola cosa di poco valore). La città gli tributa generosamente i suoi spazi pubblici dove si riversano coppie, gruppi, famiglie, attrezzati di tutto punto per godere di un pranzo o soltanto di uno spuntino all’aperto, immersi tra i panorami urbani più suggestivi. An old tradition renews the relationship existing between Paris and her inhabitants: the social and public use…
Barcelona’s Urban Markets; I mercati urbani di Barcellona
2016
I mercati non sono solo potenti dinamizzatori dell’economia urbana come luoghi del commercio di prossimità, dell’occupazione e dell’imprenditorialità, ma svolgono un importante ruolo di aggregazione sociale e di promozione culturale che concorre ai processi di rigenerazione urbana. Ben consapevole di tali funzioni, l’Ajuntament de Barcelona ha istituito nel 1991 un organismo autonomo per la gestione diretta e l’amministrazione dei mercati di Barcellona, l’IMMB (Institut Municipal de Mercats de Barcelona), che provvede anche alla modernizzazione dei mercati attraverso il miglioramento delle infrastrutture e dei servizi alla persona, l’adeguamento dell’offerta merceologica in base alle nuove …
Cascaded Multilevel Inverter-Based Asymmetric Static Synchronous Compensator of Reactive Power
2022
The topology of the static synchronous compensator of reactive power for a low-voltage three-phase utility grid capable of asymmetric reactive power compensation in grid phases has been proposed and analysed. It is implemented using separate, independent cascaded H-bridge multilevel inverters for each phase. Every inverter includes two H-bridge cascades. The first cascade operating at grid frequency is implemented using thyristors, and the second one—operating at high frequency is based on the high-speed MOSFET transistors. The investigation shows that the proposed compensator is able to compensate the reactive power in a low-voltage three-phase grid when phases are loaded by highly asymmet…
Conceptualisation et évaluation d'une typologie de lotissement vertical pour un aménagement urbain durable
2020
The current urban development process is the result of a paradoxical situation. On the one end, families prefer individual housing, which finds the favourable conditions to its spreading in the more or less distant from towns outskirts, while wishing to benefit from services (proximity to amenities, public transport offers, etc…) which are rather the corelate of dense urban centralization. On the other hand, in order to fight against environmental, social and economic costs of urban sprawl, and also aim towards a more sustainable city, the urban renovation and compact city projects lead to some density levels that only collective housing enables to reach. So, the equation - control of the u…
Artura Šniclera daiļrade mūsdienu kontekstā: Šniclera darbu recepcija Latvijā pēc 1991. gada
2018
Bakalaura darbs apskata Artura Šniclera daiļradi mūsdienu kontekstā, īpaši akcentējot Šniclera darbu recepciju Latvijā pēc 1991. Bakalaura darba mērķis ir analizēt Artura Šniclera darbu recepciju Latvijā laika periodā no 1991. gada līdz 2018. gadam. Tā kā šajā laika periodā divas reizes ir tulkots un izdots darbs ar nosaukumu „Sapņa novele” un četras reizes uzvesta luga „Riņķa dancis”, ir pamats uzskatīt, ka šie darbie tiek interpretēti ļoti dažādi. Analizējot teātra kritiķu recenzijas, tiek secināts, ka režisori Latvijā interpretē Šniclera darbu, izmantojot dažādus teātra paņēmienus, tādējādi atklājot skatītājiem autora darbu ikreiz no cita skatpunkta. Tāpat tiek secināts, ka Šniclera darb…
