On-chip purification of arc-discharge synthesized multiwalled carbon nanotubes via mobile liquid interface

2017

This thesis reports a novel approach for purification of carbon nanotube (CNT) samples deposited on smooth silicon substrates through a mobile liquid interface interacting with carbonaceous debris particles that contaminate the deposition. The method is based on physical interaction of the particles and the three-phase contact line via capillary interface forces, i.e. the surface tension, which results in the detachment of chemically indispersible colloids from the sample surface. In the experiments reported in this work, we focus primarily on arc-discharge grown multi-walled carbon nanotubes, whose synthesis is particularly plagued by carbonaceous debris that is difficult to remove without h…

A New Phylogenetic Framework for the Animal-Adapted

2018

Tuberculosis (TB) affects humans and other animals and is caused by bacteria from the Mycobacterium tuberculosis complex (MTBC). Previous studies have shown that there are at least nine members of the MTBC infecting animals other than humans; these have also been referred to as ecotypes. However, the ecology and the evolution of these animal-adapted MTBC ecotypes are poorly understood. Here we screened 12,886 publicly available MTBC genomes and newly sequenced 17 animal-adapted MTBC strains, gathering a total of 529 genomes of animal-adapted MTBC strains. Phylogenomic and comparative analyses confirm that the animal-adapted MTBC members are paraphyletic with some members more closely relate…

W więzieniu widoczności medialnej. Rozważania o mikropolityce w "ponoptykonicznej rzeczywistości"

2017

W dobie telefonów komórkowych z dostępem do Internetu, wyposażonych w cyfrowe aparaty fotograficzne, „fotoreporterem” może zostać każdy. Dziś polityk nie tylko musi potrafić dobrze się zaprezentować, ale będąc ciągle narażonym na upublicznienie, kontrolować każdy swój gest i ważyć każde słowo. Każdy błąd czy gafa szybko może przerodzić się w poważny kryzys zagrażający wizerunkowi aktora politycznego. Na ciągłą widoczność narażone są nie tylko najważniejsze osoby w państwie, ale wręcz każdy. Co równie istotne, współczesna polityka oparta jest na ciągłej medialnej widoczności. Aktywna obecność na portalach społecznościowych staje się równie ważna, o ile nie ważniejsza od tego, kto i jak głoso…

Essential oil crops for sustainable agriculture - A review

2009

Multifunctionality and diversification of farming systems, integration of agricultural practices both inter se and with the non-agricultural productive systems operating on the territory, biodiversity safeguards, and reduction in off-farm inputs, are key factors for all modern development strategies in agricultural areas. Such issues are valid worldwide, but are especially true in areas in which the cultivation of the more widespread and “classical” crops is constrained by factors of varying degree and importance. In Mediterranean areas, where many environmental and economic factors often reduce rural areas to marginal conditions, the search for new crop opportunities has become one of the …

Study of quantitative and qualitative variations in essential oils of Sicilian oregano biotypes

2015

Essential oil (EO) was extracted using hydrodistillation from samples of Origanum vulgare subspecies hirtum (Link) Ietswaart, gathered from the wild in various parts of Sicily, Italy; GC-FID and GC-MS analyses were subsequently performed. The aim of the study was to analyze the relationship between essential oil yields and the geographical distribution of oregano wild populations based on variations in environmental factors as collection sites. Moreover, the purpose was to group Origanum vulgare subspecies hirtum biotypes according to the chemical composition of the EO. The seven principal components in the EO was thymol (24.0–54.4%), γ-terpinene (9.8–30.5%), ρ-cymene (5.2–18.7%), α-terpine…

The role of the agreement as a tool for management of property relations in cases of cross border marriages and civil unions/partnerships registered …

2021

The essay examines the role of the agreement as a tool for managing property relationships in crossborder marriages and registered partnerships, in light of EU Regulations 1103 and 1104 of 2016, on the property regimes of international married or registered couples. The main prerogative of such acts is the recognition of the parties? freedom to choose the court and the applicable law. The law governing the matrimonial property regimes, or the property consequences of registered partnerships, has universal scope. This agreement in the form envisaged, which is backed by the need for legal certainty and predictability of the applicable rules, means that the spouses, in family problems which ha…

Precision Agriculture: Past, Present and Future

2011

From 1978 the Global Positioning System, needed for sensing the position of military targets (e.g. buildings, machinery), was developed as a pure military system, while in 1983 it was made available also for public use. Therefore, at the beginning of 80s precision agriculture, requiring GPS for sensing the position to which any measured field parameter must be geo-referenced, was implemented for the first time in US. In fact, soil and crop parameters are spatially variable in a field, so that spatially uniform rate crop input applications cause increased environmental impact and crop input waste. In order to reduce the environmental impact and optimise the use of crop inputs, precision agri…

Relevancia del macrófago como fuente de ligandos WNT en las complicaciones asociadas a la enfermedad de crohn

2019

La fibrosis y las fistulas son complicaciones frecuentes de la enfermedad de Crohn cuya etiopatogenia es desconocida. La cronicidad de la inflamación junto con alteraciones en la reparación tisular tras un daño, se han relacionado con estas complicaciones. Los macrófagos son células del sistema inmunitario innato ampliamente implicadas en la regulación de ambos procesos y como consecuencia en el desarrollo de la fibrosis. Estas células presentan elevada plasticidad y un continuo espectro de fenotipos funcionales que explican la diversidad de funciones que regulan. Recientes estudios han demostrado que los macrófagos, a través de vías de señalización dependientes de Stat6, actúan como fuente…

Workaholism and work engagement: how are they similar? How are they different? A systematic review and meta-analysis

2019

Workaholism and work engagement can be depicted, respectively, as the pathological and the healthy form of heavy work investment. In spite of their different definitions and outcomes on individual and organizational life, workaholism and work engagement are not clearly and adequately distinguished by scholars and researchers as they appear to show some overlapping features. The aim of this investigation was to meta-analyze available studies, selected by systematic review, on the relations between subdimensions of workaholism and work engagement. Thirty-five studies were eligible for analysis. Associations emerged between Working Excessively and Absorption (g = .34), Working Compulsively and…
