Learning Curve in Surgical Treatment of Odontoid Fixation for a Series of Type II C2 Fractures
2019
The craniovertebral junction (CVJ) is a complex anatomical area upon which most of the motion of the upper cervical spine depends [1]. Because of its unique range of motion, the CVJ is subject to several types of traumatic injury; it has been shown that odontoid fractures are the most common ones in the general population and are the most common isolated spinal fractures [2]. Accounting for up to 18% of all cervical fractures, odontoid fractures are the most common ones in elderly patients [3], in whom they account for up to 60% of spinal cord injuries [4].
Subjective and Objective Outcomes of Ankle Joint Arthrodesis with Either Ilizarov or Internal Fixation
2021
After arthroplasty, arthrodesis of the ankle joint is the most common method to treat advanced ankle osteoarthritis. The goal of the study was to assess the subjective and objective outcomes in 2 different types of fixation for ankle joint arthrodesis. We retrospectively assessed 47 patients who had undergone ankle joint arthrodesis with fixation either via an Ilizarov apparatus (group 1) (n = 21) or cannulated screws (group 2) (n = 26). The outcomes were measured by: (1) the quantity of analgesics administered, (2) the American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot score, (3) general patient satisfaction, (4) the patients' decision to undergo the same procedure given an…
Changes in Family Income around the Time of Birth of Children in Germany between 1985 and 2004
2010
Während der Verlauf und die Ursachen des Geburtenverhaltens intensiv erforscht wurden, sind die finanziellen Folgen einer Geburt empirisch kaum beachtet worden. Daher werden hier kurzfristige Wohlstandsveränderungen von Familien (hinsichtlich verfügbarem Haushaltseinkommen und Äquivalenzeinkommen) rund um die Geburt eines Kindes in längsschnittlicher Perspektive analysiert und auf ihre Ursachen untersucht. Zu diesem Zweck wurden die Daten des Sozio-oekonomischen Panels (1984-2005) mittels Fixed-Effekt-Panelregressionsmodellen analysiert. Als Ergebnis kann festgehalten werden, dass die finanziellen Folgen einer Geburt in den letzten Jahren deutlich gewachsen sind und vor allem das erste Kind…

Coincidence and common fixed points of weakly reciprocally continuous and compatible hybrid mappings via an implicit relation and an application
2015
Using the hybrid version of the notion of weakly reciprocal continuous mappings due to Gairola et al. [Coincidence and fixed point for weakly reciprocally continuous single-valued and multi-valued maps, Demonstratio Math. (2013/2014), accepted], we prove a coincidence and common fixed point theorem for a hybrid pair of compatible mappings via an implicit relation. Our main result improves and generalizes a host of previously known theorems. As an application, we give a homotopy theorem which supports our main result.
PRELIMINARY DESIGN OF AN INOFFENSIVE FIXED-WING UNMANNED AERIAL SYSTEM
2019
Aim of this paper is the preliminary design of an harmless fixed-wing unmanned Aerial System. To improve application fields, endurance has been selected as fundamental performance and the blended wing configuration has been chosen. So the fuselage has the same airfoil of the wing and contains all the payload. In this way the drag has been reduced. Because of the blended wing arrangement, to control pitch and roll elevons have been introduced. To guarantee the directional stability, winglets have been used; besides winglets increase the equivalent aspect ratio and consequently reduce the drag and improve the endurance. The selected propulsion system has been based on an electrical brushless …
Reversible inhibition of CO2fixation by ribulose 1,5-bisphosphate carboxylase/oxygenase through the synergic effect of arsenite and a monothiol
2013
The activity of the photosynthetic carbon-fixing enzyme, ribulose 1,5-bisphosphate carboxylase/oxygenase (Rubisco), is partially inhibited by arsenite in the millimolar concentration range. However, micromolar arsenite can fully inhibit Rubisco in the presence of a potentiating monothiol such as cysteine, cysteamine, 2-mercaptoethanol or N-acetylcysteine, but not glutathione. Arsenite reacts specifically with the vicinal Cys172-Cys192 from the large subunit of Rubisco and with the monothiol to establish a ternary complex, which is suggested to be a trithioarsenical. The stability of the complex is strongly dependent on the nature of the monothiol. Enzyme activity is fully recovered through …
CO2 Fixation by Copper(II) Complexes of a Terpyridinophane Aza Receptor
2004
CO2 is fixed by a Cu2+ complex of a macrocyclic terpyridinophane ligand forming a carbamate group. Several features of the structure mimic the enzyme rubisco.
On modified α-ϕ-fuzzy contractive mappings and an application to integral equations
2016
Abstract We introduce the notion of a modified α-ϕ-fuzzy contractive mapping and prove some results in fuzzy metric spaces for such kind of mappings. The theorems presented provide a generalization of some interesting results in the literature. Two examples and an application to integral equations are given to illustrate the usability of our theory.
ENVIRONMENTAL FOOTPRINT REDUCTION FOR WASTEWATER TREATMENT BY MULTI-OBJECTIVE OPTIMIZATION AND MODELLING
2020
The current challenge faced by researchers and managers is minimize the environmental footprint of wastewater treatment plants (WWTPs). To accomplish this goal, other than respect legal requirements, WWTPs must provide better responses regarding consumption of energy and resources, greenhouse gas (GHG) emissions, among others. The research hereby presented is based on the application of mathematical modelling with the aim to propose a framework for the minimization of WWTP’s environmental footprint towards optimization techniques. A literature review was held to gain knowledge regarding the main decision support systems (DSS) that are applied to WWTPs since they allow selecting the most app…
