Adaptive Control of Underactuated Underwater Vehicles

2008

This paper deals with a control strategy for underactuated underwater vehicles whose target is trajectory tracking. A cascade approach is employed which brings to a control law consisting of: a) an outer loop, obtained from the vehicle kinematic model, which forces this model to track the reference trajectory; b) an inner adaptive control loop which forces the system to track the reference signals given by the outer control loop. Conditions for asymptotic tracking of the trajectory and boundness of the unactuated velocities are given. Simulation tests illustrate the proposed approach.

Negative emotional consequences of labour market activation policies for long-term unemployed young adults in Finland

2021

PurposeThis article deals with the negative emotional consequences of active labour market policies (ALMPs) for long-term unemployed young adults in Finland. Although such policies may have positive effects, an exploration of their negative impacts reveals their problematic side effects. We explore various aspects of ALMP interventions that prevent individuals from gaining such positive outcomes and thus reduce their motivation to invest in the policies.Design/methodology/approachDrawing on the affect theory of social exchange, we understand that individuals seek positive rewards from social interactions. Our data is taken from life course interviews with unemployed people aged 20–31 in cen…

Role of post mortem computed tomography in diagnosis of upper cervical fractures in child due to road accident: A case report and literature review

2019

The upper cervical spine has unique anatomical features that distinguish it from the remainder of the cervical spine. Its motion segments make up a large amount of total cervical spine motion and, as a result,predispose it to a unique set of injuries. Cervical spine trauma is a common problem with a wide range of severity from minor ligamentous injury to section of the spinal cord. The use of post mortem CT (PMCT), and the subsequent multi-planar and volume rendering reconstruction techniques can provide non-invasive, objective operator-independent imaging data set that may be further reviewed by other specialists. and can substantially add to forensic examinations of the skeleton, especial…

Real-world experience with obeticholic acid in patients with primary biliary cholangitis

2021

Background & aims Obeticholic acid (OCA) is the second-line treatment approved for patients with primary biliary cholangitis (PBC) and an inadequate response or intolerance to ursodeoxycholic acid. We aimed to evaluate the effectiveness and safety of OCA under real-world conditions. Methods Patients were recruited into the Italian PBC Registry, a multicentre, observational cohort study that monitors patients with PBC at national level. The primary endpoint was the biochemical response according to Poise criteria; the secondary endpoint was the biochemical response according to normal range criteria, defined as normal levels of bilirubin, alkaline phosphatase (ALP), and alanine aminotransfer…

PROGETTARE L’ADATTAMENTO. Resilienze di agricoltura urbana nel contesto europeo

2022

I crescenti fenomeni legati al cambiamento climatico spingono le città a sviluppare piani di resilienza che possano rispondere in termini di sostenibilità ambientale, sociale ed economica. Le strategie nature-based possono rappresentare una soluzione; tra queste l’agricoltura urbana può contribuire ad aumentare la resilienza dei tessuti urbani europei. Questa attività è stata più volte oggetto di interesse in periodi di crisi come impegno comunitario dai caratteri sociali, oltre che produttivi ed educativi. Attraverso un excursus storico e una successiva analisi di casi studio contemporanei, il paper fornisce strumenti progettuali per intervenire nel costruito con strategie che spaziano dal…

Dual Enzyme-Triggered Controlled Release on Capped Nanometric Silica Mesoporous Supports

2012

The development of nanoscopic hybrid materials equipped with “molecular gates” showing the ability of releasing target entrapped guests upon the application of an external trigger has attracted great attention and has been extensively explored during recent years.1 These nanodevices are composed of two subunits, namely, a suitable support and certain capping entities grafted on the surface of the scaffolding.2 The support is used as a suitable reservoir in which certain chemicals can be stored whereas the molecules grafted in the outer surface act as a “gate” and can control the release of the entrapped molecules at will. Both components are carefully selected and arranged in order to achie…

The Effect of Moderate- Versus High-Intensity Resistance Training on Systemic Redox State and DNA Damage in Healthy Older Women

2018

This study investigated effects of a 16-week progressive resistance training program (RTP) with elastic bands at two different intensities on systemic redox state, DNA damage, and physical function in healthy older women. Methods: Participants were randomly assigned to the high-intensity group (HIGH; n = 39), moderate-intensity group (MOD; n = 31), or control group (CG; n = 23). The exercise groups performed an RTP twice a week with three to four sets of 6 (HIGH) or 15 (MOD) repetitions of six overall body exercises at a perceived exertion rate of 8-9 on the OMNI-Resistance Exercise Scale for use with elastic bands. Thiol redox state was determined by reduced glutathione (GSH), oxidized glu…

Krievijas Federācijas bruņojuma kontroles politika

2020

Maģistra darba „Krievijas Federācijas bruņojuma kontroles politika” mērķis ir analizēt Krievijas bruņojuma kontroles politiku Eiropas drošības kontekstā. Darbā aplūkoti teorētiskie skaidrojumi drošības konceptam, kā arī uzticību veicinošu mēru nozīme. Darba gaitā tiek skaidrots, kādi ir nosacījumi, kāpēc valstis izvēlas bruņojuma kontroles īstenošanu, kādi ir tās uzdevumi un kā tā ir attīstījusies. Lai aplūkoto Krievijas bruņojuma kontroles politiku, kā gadījumi izpētei ir izvēlēta stratēģiskā bruņojuma samazināšana, kā arī dalība konvencionālā bruņojuma kontroles mēros. Darbā analizēta Krievijas motivācija būt daļai no šiem bruņojuma kontroles mēriem, kā arī analizēta tās saistību ievēroša…
