QCD resummation effects in forward J/ψ and very backward jet inclusive production at the LHC
2017
´ We propose and study the inclusive production of a forward J/ψ and a very backward jet at the LHC as an observable to reveal high-energy resummation effects à la BFKL. Our different predictions are based on the various existing mechanisms to describe the production of the J/ψ, namely, NRQCD singlet and octet contributions, and the color evaporation model. © 2017 Copyright owned by the author(s) under the terms of the Creative Commons Attribution-NonCommercial-NoDerivatives 4.0 International License (CC BY-NC-ND 4.0).

First clinical uterus transplantation trial: a six-month report.
2014
Objective To report the 6-month results of the first clinical uterus transplantation (UTx) trial. This type of transplantation may become a treatment of absolute uterine-factor infertility (AUFI). Design Prospective observational study. Setting University hospital. Patient(s) Nine AUFI women and their live uterine donors, the majority being mothers. Intervention(s) Live-donor UTx and low-dose induction immunosuppression. Main Outcome Measure(s) Data from preoperative investigations, surgery and follow-up for 6 months. Result(s) Durations of donor and recipient surgery ranged from 10 to 13 hours and from 4 to 6 hours, respectively. No immediate perioperative complications occurred in any of …

Cholesterol Dependence of Collagen and Echovirus 1 Trafficking along the Novel α2β1 Integrin Internalization Pathway
2013
We have previously shown that soluble collagen and a human pathogen, echovirus 1 (EV1) cluster α2β1 integrin on the plasma membrane and cause their internalization into cytoplasmic endosomes. Here we show that cholesterol plays a major role not only in the uptake of α2β1 integrin and its ligands but also in the formation of α2 integrin-specific multivesicular bodies (α2-MVBs) and virus infection. EV1 infection and α2β1 integrin internalization were totally halted by low amounts of the cholesterol-aggregating drugs filipin or nystatin. Inhibition of cholesterol synthesis and accumulation of lanosterol after ketoconazole treatment inhibited uptake of collagen, virus and clustered integrin, an…

New development opportunities for the craft brewing segment: the case study of a micro-malthouse
2017
In Italy in the past few years, the number of small breweries penetrating the craft beer sector has grown exponentially. Craft producers intend to give a strong added value and a local character to their production in different ways. One of these is the use of malt derived from small batches of local cereals and pseudo cereals. The aim of this study is the assessment of investment profitability, through a cost-benefit analysis (CBA), for a compact and a modular micro-malting plant in Sicily (Southern Italy). The CBA for a micro-malthouse was carried out considering both installation and operating costs. Net present value (NPV), discounted benefit-cost ratio (DBCR) and internal rate of retur…
Organocatalytic Enantioselective Synthesis of α-Hydroxyketones through a Friedel−Crafts Reaction of Naphthols and Activated Phenols with Aryl- and Al…
2016
[EN] An efficient organocatalytic asymmetric synthesis of alpha-hydroxyketones has been developed. Quinine-derived thiourea catalyzed the enantioselective Friedel Crafts alkylation of naphthols and activated phenols with aryl- and alkylglyoxal hydrates, providing the corresponding chiral alpha-hydroxyketones with high yields (up to 97%) and excellent enantioselectivities (up to 99% ee).
Adsorption and separation of black liquor-derived phenol derivatives using anion exchange resins
2017
Abstract Kraft black liquor is the major waste stream of the paper pulping industry. This stream is usually directly incinerated in such facilities for energy production and recycling of the inorganic chemicals involved. However, lignin and other low molecular organic fragments dissolved in black liquor give rise to a large variety of aromatic fine chemicals. Energetic use of black liquor and its components prevents the removal of these valuable compounds from the waste stream. We present an easy protocol for adsorption and selective desorption of low molecular phenol derivatives from black liquor depending on the composition of the desorption system. Furthermore, adsorption experiments in …
Digitālo rīku izmantošana vēstures mācību satura apguves veicināšanai 7. klasē
2022
Diplomdarba temats: “Digitālo rīku izmantošana vēstures mācību satura apguves veicināšanai 7. klasē” (Use of digital tools to promote the acquisition of history curriculum in 7th grade). Izglītības iestāžu uzdevums ir sagatavot skolēnus reālai pasaulei un nekas nav tik aktuāls 21. gadsimta kā digitālo prasmju attīstīšana. Mācot skolēnus lietpratīgi un pareizi lietot digitālos rīkus vēstures priekšmeta ietvaros dod skolēniem pārnesamās prasmes kuras ir iespējams izmantot ārpus skolas un/vai citos priekšmetos, veidojot caurviju prasmi. Vadoties pēc Skola 2030 mērķiem ieviest izmaiņas Latvijas izglītības sistēmā ir nopietni jāaizdomājas par šīs jomas digitalizēšanu, padarot to vēl aktuālāku un…
5. un 6. klases skolēnu motivācijas aktivizēšana matemātikas apguvē, izmantojot Minecraft spēles digitālo vidi.
2021
Diplomdarbs ir izstrādāts ar mērķi izpētīt Minecraft spēles digitālās vides izmantošanas iespējas, lai aktivizētu 5. un 6. klases skolēnu mācīšanās motivāciju matemātikas apguvē. Diplomdarba aktualitāte ir saistīta ar nepieciešamību aktivizēt skolēnu mācīšanās motivāciju un iesaisti attālinātajā mācību procesā, lai veicinātu interesi par matemātikas mācību priekšmetu, kas ilgtermiņā sekmētu augstāku mācību sniegumu. Kā efektīvs rīks izvēlēta Minecraft spēles digitālā vide, tādējādi apmierinot nepieciešamību mācību procesā pielietot digitālās tehnoloģijas un spēlē balstītu mācību principus. Pētījumā konstatēts, ka Minecraft spēles digitālo vidi iespējams izmantot matemātikas stundās daudzvei…
