Two different posterior-stabilized mobile-bearing TKA designs: navigator evaluation of intraoperative kinematic differences

2020

Purpose: The purpose of this study was to compare two types of posterior-stabilized (PS) mobile-bearing (MB) total knee arthroplasties (TKAs). The hypothesis was that no major differences were going to be found among the two TKA designs. Methods: Two cohorts of patients who were divided according to implant design (Cohort A, new design gradually reducing radius PS MB TKA; Cohort B, traditional dual-radius PS MB TKA) were analyzed by means of intraoperative navigation. All operations were guided by a non-image-based navigation system that recorded relative femoral and tibial positions in native and implanted knees during the following kinematic tests: passive range of motion (PROM), varus–va…

Vibroarthrography measures joint sounds caused by sliding of the joint surfaces over each other. and can be affected by joint health, load and type of movement. Since both warm-up and muscle fatigue lead to local changes in the knee joint (e.g., temperature increase, lubrication of the joint, muscle activation), these may impact knee joint sounds. Therefore, this study investigates the effects of warm-up and muscle fatiguing exercise on knee joint sounds during an activity of daily living. Seventeen healthy, physically active volunteers (25.7 ± 2 years, 7 males) performed a control and an intervention session with a wash-out phase of one week. The control session consisted of sitting on a c…

The effect of cement fixation on initial micromotion of the femoral component in condylar knee replacement

1992

Four fresh, cadaveric specimens were fitted with total knee replacements and mounted on a knee joint loading and measuring rig. Femoral component micromotion in the sagittal plane was measured with a transducer during flexion and extension of the specimen. Various condylar designs were used without and with cement. Movement followed a characteristic curve pattern and was less with cement fixation particularly for bone of low trabecular strength as determined by bone sample tests for stiffness. Cement fixation appears to be superior to cementless fixation.

In Vitro Study on Bone Heating during Drilling of the Implant Site: Material, Design and Wear of the Surgical Drill

2020

Objective: An in vitro study was made to compare mean thermal variation according to the material, design and wear of the surgical drills used during dental implant site preparation. Material and methods: Three study groups (stainless steel drills with straight blades

Storie di oggetti (e di sogni) perduti. Musei contemporanei per ritrovarsi

2022

What happens to humanity discarded by history? To the broken dreams (of love and life)?What to do with the objects that fill our life as "fragile ruins" of a dream lost forever? The article, looking at various contemporary projects of permanent museums and temporary exhibitions, intends to outline and lead a reflection on the radical paradigm change that intervenes in the exhibition processes and in the strategies of emotional engagement within contemporary museological policies. Conceived as places of encounter and relationship, museums are open to communities and individual stories. In particular, the emotion of lost guided the constitution of collections of objects, in a series of exhibi…

A comparative analysis of the sustainability of rice cultivation technologies using the analytic network process

2010

Sustainability of local farming systems and technologies is a very important issue that faces notorious measurement difficulties. Multi-criteria methods may help researchers to solve empirical problems in the construction of composite sustainability indicators and in ranking agricultural technologies according to their sustainability. This paper shows how a multi-criteria decision-making technique, the Analytic Network Process (ANP), can be fruitfully employed to this end. Contrary to simpler and hierarchical goal-criteria-alternative approaches, in ANP all the elements in the network can be related in any possible way, which means that a network can incorporate feedback and interdependent …

Statistical study of the influence of CNTs purification and plasma functionalization on the properties of Polycarbonate-CNTs nanocomposites

2014

This work reports a statistical study on the relationship between the chemical-physical properties of CNTs, which vary by changing the conditions of purification and plasma treatment, and the macroscopic properties of PC-based nanocomposites. CNTs are synthesized and then purified in two different ways and used as fillers for the preparation of PC/CNTs nanocomposites. In some cases, oxygen plasma treatment is carried out to improve their affinity to the matrix. The CNTs are characterized by TGA, ICP/OES and FT-Raman spectroscopy, titration and morphological analysis. Mechanical, dynamic-mechanical, electrical and morphological tests are used for characterizing PC/CNTs nanocomposites.

Vajadzību analīze angļu valodas kursa skolas medmāsām izstrādei un mācīšanai

2021

Migrācijas rezultātā, arvien vairāk profesijās rodas situācijas, kurās nepieciešamas dažādu valodu zināšanas komunikācijai ar klientiem un, skolu medmāsu gadījumā – skolēniem, jeb pacientiem. Tā kā angļu valoda mūsdienās tiek uzskatīta par internacionālu valodu saziņai visā pasaulē, tāpēc šī Diplomdarba mērķis ir izpētīt, kāda vajadzību analīze būtu nepieciešama izstrādājot un mācot angļu valodas kursu skolu medmāsām. Lai sasniegtu izstrādāto mērķi, kursa autori veica medmāsu darba apraksta analīzi, skolu medmāsu anketēšanu, lai noskaidrotu vajadzības un vēlmes, interviju ar izvēlētajiem kursa dalībniekiem, dalībnieku zināšanu pārbaudi testā pēc kursa beigām, kā arī vēl vienu dalībnieku ank…
