Distribution and projections of nitric oxide synthase neurons in the rodent superior olivary complex.
2000
The superior olivary complex (SOC), a group of interrelated brainstem nuclei, sends efferents to a variety of neuronal structures including the cochlea and the inferior colliculus. The present review describes data obtained from rodents providing evidence that the gaseous, short-living neuroactive substance nitric oxide (NO) is produced in the SOC. The NO-synthesizing enzyme neuronal NO-synthase (nNOS) has been localized by means of several methods including histochemistry and immunohistochemistry. Perikarya containing nNOS were found in several nuclei of the SOC. Their largest numbers and percentages of total cells were observed in the medial nucleus of the trapezoid body. Stained terminal…
Biodistribution of Insulin-Nanogels in Mouse: A Preliminary Study for the Treatment of Alzheimer's Disease
2017
A growing body of evidence shows that Insulin, Insulin Receptor (IR) and IR signaling are involved in brain cognitive functions and their dysfunction is implicated in Alzheimer's disease (AD) neurodegeneration. Thus, administration of insulin could be a strategy for AD treatment. For this aim we have designed, synthesized and characterized a nanogel system (NG) that has been conjugated to insulin molecules (NG-In) to deliver the protein into the brain, as a tool for the development of a new therapy against AD. In our preclinical study in mice, intraperitoneal injection of fluorescent-labeled NG has allowed to determine the biodistribution of NG vs time in the whole body and its clearance th…
Distribution and generation of traps in SiO2/Al2O3 gate stacks
2007
In this work we combine charge-pumping measurements with positive constant voltage stress to investigate trap generation in SiO2/ Al2O3 n-MOSFET. Trap density has been scanned either in energy or in position based on charge-pumping (CP) measurements performed under different operating conditions in terms of amplitude and frequency of the gate pulse. Our results have revealed that the traps are meanly localized shallow in energy level, deeper in spatial position and they are mostly generated near the Si/SiO2 interface. (C) 2007 Elsevier Ltd.

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.

The Discursive Struggles of the Client–Worker Relationship in the Social Services
2020
This study examines how disability service workers identify the discourses of the client-worker relationships. We studied the clientworker relationship from the perspective of the relational dialectics theory with a focus on relational contradictions and the meanings created within discursive struggles. We analyzed the interview data from 22 social workers using contrapuntal analysis. According to the social workers’ perceptions, two discursive struggles exist in client-worker relationships: i) the struggle of integration, consisting of the contradiction of the ideal and the real and the contradiction of closeness and reservedness and ii) the struggle of certainty, consisting of the contrad…
Trap-assisted studies of odd, neutron-rich isotopes from Tc to Pd
2012
We review the present and future of trap-assisted structure studies of odd, neutron-rich Tc, Ru, Rh and Pd isotopes at the limits of present experimental techniques. These nuclei of refractory elements are produced in light-particle induced fission and filtered by their mass number with the IGISOL mass separator. Further mass separation with the JYFLTRAP Penning trap system provides a clean, monoisotopic beam perfectly suited for precise nuclear spectroscopy. Connecting the IGISOL and the JYFLTRAP facilities to the recently installed MCC30/15 cyclotron opens new prospects for post-trap spectroscopy of very exotic, neutron-rich nuclei. peerReviewed
Ion yields in HIGISOL experiments based on JYFLTRAP data and PACE4 simulations : based on JYFLTRAP data and PACE4 simulations
2012
The purpose of this thesis was to calculate ion yields in the neutron-deficient mass region A=78-111 in heavy-ion ion-guide experiments at the Ion Guide Isotope Separator On-Line (IGISOL) facility in the Accelerator Laboratory of the University of Jyväskylä. The biggest challenge was that the experiments were not designed for yield calculations but for precision mass measurements. Therefore, only a small fraction of the available data could be used. The results were compared to theoretical cross sections calculated with PACE4 code. Ion yields agreed roughly with the cross-section calculations: On the one hand, the ions with the highest cross sections were detected. On the other hand, ratios…

The transformation of the Horatian Sabine farm in Persius? Satire 6
2020
The purpose of this article is to focus on the motif of the countryside in Roman satire. In particular, it aspires to study the way the Sabine farm is delineated in Horace's Satire 2.6 and later in his Epistles, in order to elucidate the evolution of this motif in Persius? 6th Satire. In this poem, Persius addresses Caesius Bassus, who retreats to Sabine to seek poetic inspiration, but seems trapped in the paths of earlier poetry and cannot attain bliss, while the poet achieves it in the port of Luna.
