Growth of Arundo donax L. and Cyperus alternifolius L. in a horizontal subsurface flow constructed wetland using pre-treated urban wastewater - a cas…
2013
Constructed wetland systems for wastewater treatment represent an excellent opportunity for the recovery of water resources in those areas subject to prolonged periods of water shortage. This paper presents a study of the efficiency of a pilot horizontal subsurface flow system using pre-treated urban wastewater from a small town in the West of Sicily. The pilot system had a total surface area of 100 m2 with two units. Unit A was planted with Arundo donax L. and unit B with Cyperus alternifolius L. The HLR was 10 cm d-1. The main objectives of research were to evaluate the growth and biomass yield of two macrophytes and determine the removal efficiency of physical-chemical and microbiologica…

Horizontal Governance and Governance Discourses in Career Guidance and Counselling in Finland In the 2000s, horizontal governance has become a growing mode of public sector governance. In this study, we examined horizontal governance in the context of career guidance and counselling in Finland. Our empirical research data consisted of ten (10) thematic interviews with public sector officials and other experts working in the governance of guidance at the national level. Our research aim was to scrutinize how the three ideal-types in public sector governance – bureaucratic (Weberian), new public management, and new public governance – were manifested in the informants’ discourses. Our results…
MODELING PUBLIC POLICIES ANALYSIS OF LOGISTICS COLLABORATION IN THE PERFORMANCE OF THE AGRICULTURAL SECTOR OF THE POTATO IN COLOMBIA.
2020
The agricultural sector is considered fundamental for the supply of food needs of humanity, given the population growth. According to the Food and Agriculture Organization (FAO), the world population is estimated to be 9 billion people by the year 2050 and where the conditions of climate change can decrease crop yield up to 25%. This triggers greater vulnerability to the neediest population, being the rural sector the one hosting the poorest people. The rural area of Colombia represents 94% of extend the national territory, where 24% of the population lives a scenario of multiple problems that affect the country, such as the armed conflict of more than five decades, the presence of illicit …
Fuzzy sliding mode control design for a class of disturbed systems
2014
This paper discusses the problem of the fuzzy sliding mode control for a class of disturbed systems. First, a fuzzy auxiliary controller is constructed based on a feedback signal not only to estimate the unknown control term, but also participates in the sliding mode control due to the fuzzy rule employed. Then, we extend our theory into the cases, where some kind of system information can not be obtained, for better use of our theoretical results in real engineering. Finally, some typical numerical examples are included to demonstrate the effectiveness and advantage of the designed sliding mode controller. Refereed/Peer-reviewed
Partnerzy bez partnerstwa? Realizacja zasady partnerstwa w procesie wdrażania regionalnych programów operacyjnych w Polsce w perspektywie finansowej …
2021
W niniejszym artykule podjęto próbę określenia stopnia realizacji zasady partnerstwa w procesie wdrażania regionalnych programów operacyjnych (RPO) w Polsce w obecnej perspektywie finansowej (2014–2020). Przyjęto założenie, że instytucjonalnym sposobem realizacji zasady partnerstwa jest powołanie i funkcjonowanie komitetów monitorujących (KM). Analizą porównawczą objęto praktyczne aspekty działania komitetów w ramach RPO w trzech województwach: lubuskim, świętokrzyskim i kujawsko-pomorskim. Do celów porównawczych wykorzystano następujące parametry instytucjonalno-organizacyjne: liczba posiedzeń komitetów w perspektywie finansowej 2014–2020, liczba przeprowadzonych procedur głosowania obiego…
The universal ancestor : an unfinished reconstruction
2015
El cenancestro se define como el ultimo ancestro comun de todos los seres vivos que existen actualmente. Su naturaleza se ha inferido a partir de la identificacion de los genes homologos entre los linajes de arqueas, bacterias y eucariontes. Estas inferencias indican que el cenancestro poseia un sistema de traduccion de proteinas relativamente moderno y era similar en complejidad a una celula actual. Sin embargo, las enzimas claves que se encargan tanto de la replicacion del material genetico como de la biosintesis de membranas celulares no son homologas entre los linajes celulares. Aqui revisamos brevemente la historia del concepto del ultimo ancestro comun y las distintas hipotesis que se…
Preceding Host History of Conjugative Resistance Plasmids Affects Intra- and Interspecific Transfer Potential from Biofilm
2023
Conjugative plasmids can confer antimicrobial resistance (AMR) to their host bacterium. The plasmids disperse even between distantly related host species, rescuing the host from otherwise detrimental effects of antibiotics. Little is known about the role of these plasmids in the spread of AMR during antibiotic treatment. One unstudied question is whether the past evolutionary history of a plasmid in a particular species creates host specificity in its rescue potential or if interspecific coevolution can improve interspecific rescues. To study this, we coevolved the plasmid RP4 under three different host settings; solely Escherichia coli or Klebsiella pneumoniae, or alternating between both …
Inequality in Healthcare Utilization in Italy: How Important Are Barriers to Access?
2022
With the ageing population, equitable access to medical care has proven to be paramount for the effective and efficient management of all diseases. Healthcare access can be hindered by cost barriers for drugs or exams, long waiting lists or difficult access to the place where the needed healthcare service is provided. The aim of this paper is to investigate whether the probability of facing one of these barriers varies among individuals with different socio-economic status and care needs, controlling for geographical variability. Methods. The sample for this study included 9629 interviews with Italian individuals, aged 15 and over, from the second wave (2015) of the European Health Intervie…

Small things matter : of phages and antibiotic resistance conferring plasmids
2016
Viruses and plasmids are small units of genetic material dependent on cells either transiently or continuously. Intriguingly, stories of these small entities intertwine in antibiotic resistance crisis. Horizontal gene transfer enables bacteria to respond rapidly to chances in their environment. Anthropogenic consumption of antibiotics induces the travel of resistance encoding genes mainly as passengers of conjugative plasmids. In this thesis, I demonstrate that clinically important resistance plasmids could evolutionarily rescue susceptible bacteria under lethal antibiotic concentrations. If mobile resistance genes are available in surrounding community, administration of high doses of anti…
