Appropriate technology in a Solovian nonlinear growth model

2007

We propose a Solovian growth model with a convex-concave production function and international technological spillovers. We test the empirical implications of the model, analysing the effects of the productivity slowdown that followed the oil shocks of the 1970s. We argue that this slowdown, altering the world income distribution, affected the pattern of international technological spillovers, taking the poorest countries further away from the technological leaders, and therefore unable to exploit their technologies. The result is the emergence of a poverty trap for low-income countries.

La Sindrome Compartimentale Addominale (ACS) dopo chirurgia dell'Aneurisma dell'Aorta Addominale (AAA)

2009

Introduction: The Abdominal Compartment Syndrome (ACS) is a “condition in which increased tissue pressure in a confined anatomic space, causes decreased blood flow leading to ischaemia and dysfunction and may lead to permanent impairment of function” Materials and Methods: between june 2007 and june 2008 we treated surgically 23 cases of AAA (14 in election and 9 in emergency), with indirect intra-abdominal pressure (IAP) monitoring (intra-vescical catheter). Mean age was 68 (64-84) years. Mean transverse diameter was 6,2 cm (min 5,5 e max 9,0). Rise in IAP more then 20 mmHg was considered for surgical decompression. In 1 case we registered preoperatively IAP more than 20 mmHg treated with …

LA VARIABILITA’ PRESSORIA A BREVE TERMINE NON E’ ASSOCIATA ALLA DISFUNZIONE RENALE LIEVE NELL'IPERTENSIONE ARTERIOSA PRIMARIA

2014

RAZIONALE. Il significato prognostico della variabilità pressoria (VP) a breve termine, espressa come deviazione standard (SD), è controverso. Recentemente sono stati proposti altri indici di VP a breve termine, tra i quali l’Average Real Variability (ARV), sembra essere maggiormente associato al rischio cardiovascolare (CV). Non indagata, finora è la relazione tra ARV e disfunzione renale lieve. Scopo del nostro studio è stato quello di analizzare le relazioni dell’ ARV delle 24 h e di altri indici di VP a breve termine con l’ albuminuria (AER) ed il filtrato glomerulare (eGFR) in un gruppo di ipertesi essenziali, non trattati. CASISTICA E METODI. Sono stati arruolati 248 pazienti (età med…

Building sustainable contextual ambidexterity through routines: a case study from information technology firms

2020

The purpose of this paper is to explain the role that routines play in achieving sustainable organisational ambidexterity in information technology (IT) firms. Our exploratory analysis of four case studies reveals the key importance of routines in setting the context for sustainable ambidexterity. Companies build up contextual ambidexterity through routines derived from normalization of processes, normalization of skills, and normalization of results. The findings of the study show that routines support IT professionals to decide whether to exploit or explore in each particular case. Firstly, the enabling character of explicit routines as a result of the normalisation of work processes and …

Usability and acceptability of a fall monitoring system

2017

Falls and injurious falls affect one third of the older people. Those experiencing a fall might be unable to call for help remaining unattended for a long time. Pain, hypothermia and dehydration are common consequences. Additionally, ensuing fear of falling may reduce physical activity leading to functional decline and possibly institutionalization. Monitoring fall events the CONFIDENCE system could summon emergency assistance automatically thus reducing the negative consequences of falls. This thesis is part of the European FP7 project “Ubiquitous care system to support independent living” (CONFIDENCE) which developed a fall monitoring system based on three-dimensional (3D) localization of…

Phytoplankton group identification with chemotaxonomic biomarkers: In combination they do better

2023

Chemotaxonomic biomarkers are needed to monitor and evaluate the nutritional quality of phytoplankton communities. The biomolecules produced by different phytoplankton species do not always follow genetic phylogeny. Therefore, we analyzed fatty acids, sterols, and carotenoids from 57 freshwater phytoplankton strains to evaluate the usability of these biomolecules as chemotaxonomic biomarkers. We found 29 fatty acids, 34 sterols, and 26 carotenoids in our samples. The strains were grouped into cryptomonads, cyanobacteria, diatoms, dinoflagellates, golden algae, green algae, and raphidophytes, and the phytoplankton group explained 61%, 54%, and 89% of the variability of fatty acids, sterols, …

Monitoring Risk Factors and Improving Adherence to Therapy in Patients With Chronic Kidney Disease (Smit-CKD Project): Pilot Observational Study

2022

Background Chronic kidney disease is a major public health issue, with about 13% of the general adult population and 30% of the elderly affected. Patients in the last stage of this disease have an almost uniquely high risk of death and cardiovascular events, with reduced adherence to therapy representing an additional risk factor for cardiovascular morbidity and mortality. Considering the increased penetration of mobile phones, a mobile app could educate patients to autonomously monitor cardiorenal risk factors. Objective With this background in mind, we developed an integrated system of a server and app with the aim of improving self-monitoring of cardiovascular and renal risk factors and…

Rapid Quantification of Microalgae Growth with Hyperspectral Camera and Vegetation Indices

2021

Spectral cameras are traditionally used in remote sensing of microalgae, but increasingly also in laboratory-scale applications, to study and monitor algae biomass in cultures. Practical and cost-efficient protocols for collecting and analyzing hyperspectral data are currently needed. The purpose of this study was to test a commercial, easy-to-use hyperspectral camera to monitor the growth of different algae strains in liquid samples. Indices calculated from wavebands from transmission imaging were compared against algae abundance and wet biomass obtained from an electronic cell counter, chlorophyll a concentration, and chlorophyll fluorescence. A ratio of selected wavebands containing near…
