Changements à court terme de la composition des communautés de champignons mycorhiziens à arbuscules et des populations de Rhizophagus irregularis en…
2014
La mycorhize à arbuscule a un important potentiel d’amélioration de la nutrition minérale des plantes, fort utile dans le contexte agricole. Cependant, certaines pratiques culturales sont connues pour avoir un effet néfaste sur la diversité des champignons mycorhiziens à arbuscules (Glomeromycètes). Il est donc nécessaire de mieux comprendre les dynamiques de leurs communautés et populations pour pouvoir préserver et gérer le potentiel symbiotique. Dans cette étude, nous avons étudié les effets séparés et conjoints du retournement du sol et des fertilisations phosphatée et azotée du sol sur la structure des communautés des Glomeromycètes et sur les populations de l’espèce Rhizophagus irregu…
MOBILE MAPPING FOR CULTURAL HERITAGE: THE SURVEY OF THE COMPLEX OF ST. JOHN OF THE HERMITS IN PALERMO (ITALY)
2023
Abstract. During the 11th and 12th century, the Arab-Norman architectural style characterized the most beautiful and important Cultural Heritage buildings in Sicily, and especially in Palermo (Italy). The relevance of these monuments is highlighted by their inclusion in the UNESCO World Heritage Sites List in 2015. For many years, the University of Palermo has been studying and documenting several Arab-Norman cultural assets, and in particular, the complex of St. John of the Hermits in Palermo (Italy). A first detailed 3D survey of the main structures of this complex was carried out using a terrestrial laser scanner while the 3D survey of the entire complex was made using a Mobile Mapping S…
Plūsmas stāvokļa saistība ar daudzspēlētāju tiešsaistes lomu spēļu lietošanu un emociju regulāciju
2018
Pētījuma mērķis ir noskaidrot kādas saistības pastāv starp plūsmas stāvokli, emociju kontroli un daudzspēlētāju tiešsaistes spēļu lietošanu. Pētījumā piedalījās 56 dalībnieki vecumā no 14 – 45 gadiem, no kuriem 43 (77%) ir vīrieši un 13 (23%) sievietes. Kā datu ievākšanas metodes tika izmantotas trīs aptaujas. Pirmā ir Dispozicionālā plūsmas stāvokļa skala (Dispositional Flow Scale 2 (DFS-2)), Jackson, S. A., & Eklund, R. C. (2002), kura tika adaptēta šī bakalaura darba ietvaros. Otra aptauja ir Problematic Online Gaming Questionnaire (Demetrovics, Z., Urban, R. et al., 2012), Problemātiska tiešsaistes spēļu spēlēšanas skala, kuru savā bakalaura darbā adaptējusi Anna Siliņa (2013). Trešā ir…
Phase I trial of thymidylate synthase poly-epitope peptide (TSPP) vaccine in advanced cancer patients.
2015
Thymidylate synthase (TS) poly-epitope peptide (TSPP) is a 27-mer peptide vaccine containing the amino acidic sequences of three epitopes with HLA-A2.1-binding motifs of TS, an enzyme overexpressed in cancer cells, which plays a crucial role in DNA repair and replication. Based on the results of preclinical studies, we designed a phase Ib trial (TSPP/VAC1) to investigate, in a dose escalation setting, the safety and the biological activity of TSPP vaccination alone (arm A) or in combination with GM-CSF and IL-2 (arm B) in cancer patients. Twenty-one pretreated metastatic cancer patients, with a good performance status (ECOG ≤ 1) and no severe organ failure or immunological disease, were enr…
HTLS Conductors: A Way to Optimize RES Generation and to Improve the Competitiveness of the Electrical Market—A Case Study in Sicily
2018
Stringent environmental constraints make more difficult to identify new energy corridors and build new power lines. The increase in the generation of electricity from renewable energy sources (RESs) makes the operation of electrical systems increasingly difficult in some areas. The transmission system operators (TSOs), in Italy Terna, are forced to exploit the existing overhead transmission lines, increasing the possibility of dispatching energy, in particular RES, optimizing the transmission capacity. Therefore, after a brief presentation of the Sicilian electricity system and a brief description of high-temperature low-sag (HTLS) conductors, a case study is presented. It is shown how it i…
A generalization of the orthogonal regression technique for life cycle inventory
2012
Life cycle assessment (LCA) is a method used to quantify the environmental impacts of a product, process, or service across its whole life cycle. One of the problems occurring when the system at hand involves processes delivering more than one valuable output is the apportionment of resource consumption and environmental burdens in the correct proportion amongst the products. The mathematical formulation of the problem is represented by the solution of an over-determined system of linear equations. The paper describes the application of an iterative algorithm for the implementation of least square regression to solve this over-determined system directly in its rectangular form. The applied …
Descriptor-type Kalman Filter and TLS EXIN Speed Estimate for Sensorless Control of a Linear Induction Motor.
2014
This paper proposes a speed observer for linear induction motors (LIMs), which is composed of two parts: 1) a linear Kalman filter (KF) for the online estimation of the inductor currents and induced part flux linkage components; and 2) a speed estimator based on the total least squares (TLS) EXIN neuron. The TLS estimator receives as inputs the state variables, estimated by the KF, and provides as output the LIM linear speed, which is fed back to the KF and the control system. The KF is based on the classic space-vector model of the rotating induction machine. The end effects of the LIMs have been considered an uncertainty treated by the KF. The TLS EXIN neuron has been used to compute, in …
Nogāžu procesu monitorings ar lāzerskenēšanas metodi
2019
Pētījuma ietvaros, nogāžu procesu attīstības novērošanai, tika izmantots sauszemes lāzerskeneris Faro FocusS 70. Lauka pētījumi veikti trīs etalonteritorijās, apsekojot – Vizuļu iezi, noslīdeni, netālu no Zanderu kapiem, pie Līgatnes un noslīdeni, netālu no Gūtmaņalas, pie Siguldas. Lāzerskenēšana veikta 2018. gada rudenī un 2019. gada pavasarī. Lauka pētījumu laikā etalonteritorijās izveidoti paliekoši atbalsta punkti, kas vēlāk izmantoti atkārtotā apsekojuma laikā. Lai piesaistītu skenēto materiālu koordināšu tīklam, atbalsta punktiem noteiktas koordinātas, izmantojot GNSS. Virs tiem 2 m augstumā tika uzstādīti statīvi ar sfērām un apkārtnē pie noslīdeņa/atseguma virsmas, to tuvumā vai pi…
The Church of S. Maria Delle Palate in Tusa (Messina, Italy): Digitization and Diagnostics for a New Model of Enjoyment
2022
Cultural places represent the tangible part of the identity and historical heritage of a civilization as well as an extraordinary driving force for the economic development of a country. Within its huge asset, Italy counts a wide number of archaeological sites and monuments which, despite their cultural value, are totally cut off from the most important cultural routes. This paper aims to demonstrate how specific actions of digitization can contribute to valorize (restoring a cultural value) ‘marginal’ landmarks, promoting their knowledge and inclusion. The case study described is represented by the Church of “Santa Maria delle Palate”, located inside the well-known …
Stromal and Immune Cell Dynamics in Tumor Associated Tertiary Lymphoid Structures and Anti-Tumor Immune Responses
2022
Tertiary lymphoid structures (TLS) are ectopic lymphoid organs that have been observed in chronic inflammatory conditions including cancer, where they are thought to exert a positive effect on prognosis. Both immune and non-immune cells participate in the genesis of TLS by establishing complex cross-talks requiring both soluble factors and cell-to-cell contact. Several immune cell types, including T follicular helper cells (Tfh), regulatory T cells (Tregs), and myeloid cells, may accumulate in TLS, possibly promoting or inhibiting their development. In this manuscript, we propose to review the available evidence regarding specific aspects of the TLS formation in solid cancers, including 1) …
