Evaluation of debris flow susceptibility in El Salvador (CA): a comparison between Multivariate Adaptive Regression Splines (MARS) and Binary Logisti…
2018
In the studies of landslide susceptibility assessment, which have been developed in recent years, statistical methods have increasingly been applied. Among all, the BLR (Binary Logistic Regression) certainly finds a more extensive application while MARS (Multivariate Adaptive Regression Splines), despite the good performance and the innovation of the strategies of analysis, only recently began to be employed as a statistical tool for predicting landslide occurrence. The purpose of this research was to evaluate the predictive performance and identify possible drawbacks of the two statistical techniques mentioned above, focusing in particular on the prediction of debris flows. To this aim, an…
Development of Municipal Solid Waste Management
2015
This paper is based on an empirical work done by author on a series of case studies such us document studies and analyzing the best practices examples. The objective of this research is to find out barriers to reach regional waste management plan demands in three municipalities: Salacgriva, Saulkrasti and Ikskile. Author gives proposal with some recommendations for development of municipal waste management as well. There are several views and attitudes of local stakeholders such us municipality, waste producers, waste collectors and mediators on how to manage collection and transportation of solid waste in practice as well as on public involvement in the process.. Passivity of stakeholders …
High myopic patients with and without foveoschisis: morphological and functional characteristics.
2020
Purpose: Myopic foveoschisis (MF) is characterized by the splitting of the retinal layers in the fovea of patients with high myopia (HM). MF may progress into foveal detachment or macular hole formation with consequent loss of central vision. The aim of this study is to investigate morphological and functional changes of the macular region in myopic subjects with and without foveoschisis. Design: Observational, cross-sectional, comparative study. Methods: Forty-eight patients with HM and 24 healthy controls were evaluated by spectral domain-optical coherence tomography (SD-OCT), multifocal electroretinography (mfERG) and microperimetry (MP-1) tests to assess macular thickness, functionality…
Collaboration between non-governmental organizations and educational leaders in capacity development in rural South Africa
2013
Skills development has been a point of urgency since the advent of progressive governance in democratic South Africa. Despite many efforts through the National Skills Development Strategies and partnerships, the situation still remains worrisome especially in rural context. The study aimed to identify how the NGOs and education leaders collaborate in skills development, its impact, and possible ways of optimizing such practices. A methodology that considers the perspectives of individuals experiencing the phenomenon was invoked. Accordingly, this study exploits the phenomenological approach. Participants were purposely selected from Sector Education Training Authorities and NGOs involved in…
Nanotechnology in restoration: cleaning and consolidation of stonework
2011
Nanotechnology is a science that utilises methods and techniques to manipulate material on a size-scale smaller than a micrometre (normally between 1 and 100 nanometres) and has the aim of producing materials with particular chemical-physical characteristics. It constitutes a true multi-disciplinary sphere of investigation, involving numerous areas of research, ranging from molecular biology to chemistry, from the science of materials to (applied and basic) physics, to mechanical and electronic engineering. Nanotechnology’s present and future applications render this an issue of great current interest, bearing in mind not only its innovative character, but also its possible impact on indust…
Rectal perforation during defecography: extraluminal barium impaction removed by TEM (Transanal Endoscopic Microsurgery).
2016
Defecography is the standard diagnostic technique for the diagnosis of functional disorders of the posterior pelvic compartment. However it has some limits as radiation exposure, low-contrast resolution, some degrees of embarrassment and discomfort for the patients. Furthermore it often fails to directly visualize the changes that affect the pararectal space. Here we present a never described case of rectal perforation after defecography with barium impaction removed by TEM (Transanal Endoscopic Microsurgery).We present a case of a 50 years old woman with extraluminal barium impaction due to perforation occurred during defecography. Both pelvic MR and endoanal ultrasound confirmed the prese…
Contributi alla interpretazione, conservazione e restauro dei manufatti storico-artistici dell’Orto Botanico di Palermo: il Paride di Nunzio Morello
2017
Contributions to the interpretation, conservation and restoration of the historical and artistic artifacts of the Botanical Garden of Palermo: the Paride by Nunzio Morello – Purely cognitive and conservative requirements of the historical-artistic heritage of the Botanical Garden of the University of Palermo, have led the authors to present one of the most representative monuments of such Garden that is of great artistic and cultural value in the City of Palermo: the Paride Pensante, a marble sculpture made in 1839 by the Palermo sculptor Nunzio Morello - a pupil of the most famous artist Valerio Villareale - donated to his homeland and placed in the men- tioned Botanical Garden, in the squ…
Bedside surgery in the newborn infants: Survey of the Italian society of pediatric surgery
2020
Abstract Introduction This is the report of the first official survey from the Italian Society of Pediatric Surgery (ISPS) to appraise the distribution and organization of bedside surgery in the neonatal intensive care units (NICU) in Italy. Methods A questionnaire requesting general data, staff data and workload data of the centers was developed and sent by means of an online cloud-based software instrument to all Italian pediatric surgery Units. Results The survey was answered by 34 (65%) out of 52 centers. NICU bedside surgery is reported in 81.8% of the pediatric surgery centers. A lower prevalence of bedside surgical practice in the NICU was reported for Southern Italy and the islands …
Individual baseline behavioral traits predict the resilience phenotype after chronic social defeat
2021
Abstract Chronic social defeat (CSD) has been widely used as a psychosocial stress model in mice, with the magnitude of CSD-induced social avoidance as the major behavioral hallmark of the resilient and susceptible groups. Despite significant progress in the study of the neurobiology of resilient and susceptible mice, the nature and ethological relevance of CSD-induced social avoidance and social approach, particularly measured using a CD1 mouse, needs conceptual clarification. Based on the findings of a recent study revealing substantial individuality in genetically homogeneous inbred mice, we investigated whether certain baseline individual characteristics of male C57BL/6J mice predict th…
Combination of acoustic levitation with small angle scattering techniques and synchrotron radiation circular dichroism. Application to the study of p…
2016
Abstract Background The acoustic levitation technique is a useful sample handling method for small solid and liquids samples, suspended in air by means of an ultrasonic field. This method was previously used at synchrotron sources for studying pharmaceutical liquids and protein solutions using x-ray diffraction and small angle x-ray scattering (SAXS). Methods In this work we combined for the first time this containerless method with small angle neutron scattering (SANS) and synchrotron radiation circular dichroism (SRCD) to study the structural behavior of proteins in solutions during the water evaporation. SANS results are also compared with SAXS experiments. Results The aggregation behavi…
