Prognostic Factors in Staged Bilateral Total Knee Arthroplasty—A Retrospective Case Series Analysis
2023
Background: Bilateral osteoarthritis of the knee is an indication for a bilateral total knee replacement (TKR) procedure. The goal of our study was to assess the sizes of the implants used during the first and second stages of TKR procedures in order to compare their size and identify the prognostic factors for the second procedure. Methods: We evaluated 44 patients who underwent staged bilateral TKR procedures. We assess the following prognostic factors from the first and second surgery: duration of anesthesia, femoral component size, tibial component size, duration of hospital stay, tibial polyethylene insert size, and the number of complications. Results: All assessed prognostic factors …
Tecniche di Produzione del Cemento Traslucido
2012
The aim of the paper is to investigate different techniques used by some companies nowadays involved in the production of panels or blocks made of translucent cement. For doing that, the patents registered all over the world starting from the 2000 have been studied in deep, in order to acquire more detailed information about the techniques of production and to overcome the limits due to the lack of information about this subject that is difficult to find in literature. Particularly, patents by LitraConTM, Luccon, Lucem, Italcementi have been investigated; these last four industries are, at the moment, the only ones able to make in Europe translucent cement elements by using different techni…
Impacts des réseaux viaires sur les mobilités urbaines : quelques illustrations
2008
This research aims to find the impact of the network shape and structure on the urban mobilities, in order to fight against the automobile dependency and to include the externalities in the network design. Three examples illustrate this objective. The first one shows the influence of the network shape on the pedestrian urban flows. The second one emphasizes how sensitive to the network structure is the efficiency of a very flexible Demand Responsive Transport. The third example demonstrates that the network metric is favourable to the automobile and how it can be possible to apply an alternative metric, called the “slow metric” to reduce the urban sprawling and the automobile dependency.
Job Displacement, Inter-Regional Mobility and Long-Term Earnings
2018
We examine the effect of job displacement on regional mobility using linked employer-employee panel data for the 1995-2014 period. We also study whether displaced movers obtain earnings and employment gains compared to displaced stayers. The results show that job displacement increases the migration probability by ~70%. However, social capital in a region and housing characteristics decrease the propensity to move, indicating that people do not make the migration decisions solely based on short-term economic incentives. Migration has an immediate negative relationship with earnings, but the link diminishes as time passes and eventually turns positive for men. The link between migration and …
Losing a Job and (Dis)incentives to Move
2020
Tässä tutkimuksessa tarkastellaan työpaikan menettämisen ja muiden taloudellisten ja ei-taloudellisten kannustimien vaikutuksia alueelliseen muuttoliikkeeseen. Käytämme yhdistettyä työnantaja-työntekijäaineistoa sekä tietoja alueellisista asuntomarkkinoista. Työpaikan menettäneillä tarkoitamme heitä, jotka menettävät työpaikkansa toimipaikan sulkemisen tai joukkoirtisanomisen takia. Työpaikan menetys lisää henkilön muuttoalttiutta noin 80 prosentilla. Työpaikan menettäneet näyttäisivätkin reagoivan taloudellisiin kannustimiin, sillä alhainen oletettu palkkataso ja korkeat asuntojen hinnat alueella ovat yhteydessä lisääntyneeseen muuttoalttiuteen alueelta, josta henkilö on jäänyt työttömäksi…
Uuden uran edessä: ohjausympäristöt irtisanomisen jälkeen ICT-alan ammattilaisten kokemana
2016
Jurmu, Jorma. 2016. UUDEN URAN EDESSÄ. Ohjausympäristöt irtisanomi-sen jälkeen ICT-alan ammattilaisten kokemana. Kasvatustieteen pro gradu -tutkielma. Jyväskylän yliopisto. Opettajankoulutuslaitos. 102 s. Tutkimuksen tavoitteena on tarkastella ohjausta ja ohjausympäristöjä ict-alan ammattilaisten näkökulmasta irtisanomistilanteen jälkeen. Ilmiö avautuu tässä tutkimuksessa ohjauskokemusten ja niihin liittyvien odotusten kautta. Tutkimustehtävänä on selvittää, miten tehostetut ohjaukselliset toimet edistävät ict-alan ammattilaisten siirtymistä uralla eteenpäin irtisanomisen jälkeen. Tämä kvalitatiivinen tutkimus rakentui fenomenologisella tutkimusotteella. Tutkimukseen osallistui kahdeksan EG…
Analysis of requirements for valve accuracy and repeatability in high efficiency digital displacement motors
2018
Traditional variable displacement piston machines achieve high efficiency when operating at high displacements, but struggle with poor efficiency at low displacements. The pistons are connected to high pressure and low pressure in conjunction with the output shaft position and the displacement is changed by changing the piston stroke, resulting in almost constant friction, leakage, and compressibility losses independent of displacement. In digital displacement machines, the rotary valve is replaced by two fast switching on/off valves connected to every cylinder. By controlling the fast switching on/off valves, the cylinders can be controlled individually and friction, leakage and compressib…
Modelling the effect of ethanol on growth rate of food spoilage moulds
2005
The effect of ethanol (E) on the radial growth rate (mu) of food spoilage moulds (Aspergillus candidus, Aspergillus flavus, Aspergillus niger, Cladosporium cladosporioides, Eurotium herbariorum, Mucor circinelloides, Mucor racemosus, Paecilomyces variotii, Penicillium chrysogenum, Penicillium digitatum, Rhizopus oryzae and Trichoderma harzianum) was assessed in Potato Dextrose Agar (PDA) medium at a(w) 0.99, 25 degrees C. In order to model this effect, the Monod type equation described previously by Houtsma et al. (Houtsma, P.C., Kusters, B.J.M., de Wit, J.C., Rombouts, F.M., Zwietering, M.H., 1994. Modelling growth rates of Listeria monocytogenes as a function of lactate concentration. Int…

The complete mitochondrial genome of the wood tiger moth (Arctia plantaginis) and phylogenetic analyses within Arctiinae
2021
We report the assembly and annotation of the complete mitochondrial genome of the warningly-coloured wood tiger moth (Arctia plantaginis) and investigate its phylogenetic position within Arctiinae. The A.plantaginis mitogenome is 15,479 bp long with 13 protein-coding genes, 22 transfer RNAs, 2 ribosomal RNA genes, and an A + T-rich region (D-loop). The phylogenetic analyses based on 13 protein-coding genes showed A.plantaginis clustering within a clade of species with white wings and yellow or red bodies. This result can be useful in understanding the evolution of coloration in Arctiid moths. Peer reviewed
