Influence of long chain branching on the elongational behaviour of different polyethylenes and their blends
1986
Elongational data on a series of polyethylenes with different structure and on their blends are presented in order to correlate the extensional behaviour with the long chain branching degree.
Abitare in estensione
2014
Il saggio “Abitare in estensione” costituisce un’articolata premessa ai diversi contributi presenti nel volume esito delle attività dell’Unità di ricerca della Facoltà di Architettura di Palermo del Prin 2009 dal titolo Dalla campagna urbanizzata alla “città in estensione”: le norme compositive dell’architettura del territorio dei centri minori (Coordinatore nazionale Prof. Lugi Ramazzotti, responsabile dell’UDR locale Prof. Andrea Sciascia). Dalla stesura del modello B alla pubblicazione finale del Prin trascorrono in media tre anni. Anzi, qualche mese in meno, in considerazione dei tempi sempre più brevi imposti dalle nuove norme che regolano la rendicontazione finale. Durante questo peri…

A strong electroweak phase transition from the inflaton field
2016
We study a singlet scalar extension of the Standard Model. The singlet scalar is coupled non-minimally to gravity and assumed to drive inflation, and also couple sufficiently strongly with the SM Higgs field in order to provide for a strong first order electroweak phase transition. Requiring the model to describe inflation successfully, be compatible with the LHC data, and yield a strong first order electroweak phase transition, we identify the regions of the parameter space where the model is viable. We also include a singlet fermion with scalar coupling to the singlet scalar to probe the sensitivity of the constraints on additional degrees of freedom and their couplings in the singlet sec…
The Effect of the Cranial Electrotherapy on the Muscle Motor Function in Different Operating Modes
2015
The aim of the present study was to analyze the effect of cranial electrotherapy stimulation on muscle function analysis indicators. Instrumental assessment of muscle function (on a REV9000, Technogym, Italy) was performed before and after cranial electrotherapy stimulation, assessments of the muscle function was performed during knee extension maximum voluntary, isometric contraction (MVIC), angle velocity with load 45Nm isotonic contraction and maximum pick torque in isokinetic contraction on 30°/s, 200°/s and 300°/s and neuromuscular efficiency measurements. To analyze data was used Excel program Statistics 3.1. Subjects of our study were twenty healthy athletes of sport fitness. 1 minu…
Effect of conjugated system extension on structural features and electron-density distribution in charge–transfer difluoroborates
2021
A comparative structural study of two related donor–acceptor pyridine-based BF2 complexes, namely, 3-(dimethylamino)-1,1-difluoro-1H-pyrido[1,2-c][1,3,5,2]oxadiazaborinin-9-ium-1-uide, C8H10BF2N3O (1), and 3-{(1E,3E)-4-[4-(dimethylamino)phenyl]buta-1,3-dien-1-yl}-1,1-difluoro-1H-pyrido[1,2-c][1,3,5,2]oxadiazaborinin-9-ium-1-uide, C18H18BF2N3O (2), containing a dimethylamino group and either the shortest (in 1) or the longest (in 2) charge-transfer path known until now in this family of compounds, is presented. Single-crystal X-ray diffraction analysis supported by computational investigations shed more light on these systems, indicating, among other aspects, the predominance of C—H...F cont…
Mākslīgo skropstu pieaudzēšanas ietekme uz acs priekšējo struktūru veselību.
2020
Maģistra darbs ir uzrakstīts 60 lappusēs angļu valodā. Tas satur 23 attēlus, 45 informācijas avotus un 9 pielikumus. Mērķis: šī pētījuma mērķis ir noskaidrot, kādas acu izmaiņas ir notikušas vienu nedēļu pēc daļēji noturīgo skropstu pieaudzēšanas. Metodes: septiņiem pētījuma dalībniekiem tika četras reizes novērtētas konjunktīvas izmaiņas, asaru apjoma izmaiņas un alerģijas rādītājs, izmantojot arī subjektīvas anketas. Rezultāti: visiem šī pētījuma dalībniekiem bija daži ar daļēji noturīgu skropstu pieaudzēšanu saistīti acu simptomi, vairumam dalībnieku bija konjunktīvas apsārtums dažādos līmeņos, un daudziem bija asaru apjoma izmaiņas. Subjektīvi vissatraucošākie simptomi bija sausas/kairi…
Decentralized Deployment of Mobile Sensors for Optimal Connected Sensing Coverage
2008
In this paper, we address the optimal connected sensing coverage problem, i.e., how mobile sensors with limited sensing capabilities can cooperatively adjust their locations so as to maximize the extension of the covered area while avoiding any internal “holes”, areas that are not covered by any sensor. Our solution consists in a distributed motion algorithm that is based on an original extension of the Voronoi tessellation.
Scatter search for an uncapacitated p-hub median problem
2015
Scatter search is a population-based method that has been shown to yield high-quality outcomes for combinatorial optimization problems. It uses strategies for combining solution vectors that have proved effective in a variety of problem settings. In this paper, we present a scatter search implementation for an NP -hard variant of the classic p-hub median problem. Specifically, we tackle the uncapacitated r-allocation p-hub median problem, which consists of minimizing the cost of transporting the traffics between nodes of a network through special facilities that act as transshipment points. This problem has a significant number of applications in practice, such as the design of transportati…
