Abstract:
Personality Disorders in Brazilian Homeless Compared with Non-Psychiatric and Psychiatric Patients  [PDF]
Daniel Bartholomeu, José M. Montiel, Geraldo A. Fiamenghi Jr., Lucas F. Carvalho, Mara Rubia C. A. Orsini, Cecilia R. Ribeiro
Psychology (PSYCH) , 2015, DOI: 10.4236/psych.2015.68099
Abstract: Personality disorders are regarded as conditions that involve a maladaptive personality functioning. Homelessness is a worldly debated phenomenon. The present study aimed to understand the situation of homelessness related to the health sector, instead of considering it only as a social or economic problem. Research was conducted with three different groups, male and female, living in a Metropolitan area of Southeast Brazil, the first composed of 71 homeless people; the second, 74 psychiatric patients; and the third, 250 college students that completed the Personality Disorders Dimensional Inventory (IDTP). A logit regression model and ROC curve were used to analyse data. Results showed that homeless people scored higher in all dimensions, especially Antisocial and Schizotypal, compared with the other groups. Although the number of participants was reduced to only one part of the country, as well as the correlational design preventing clearer causal inferences, the results of this research call the attention for the need of new investigations to homeless people’s mental health, aiming to focus on public health policies that could deal with the problem.
Near-surface profiles of aerosol number concentration and temperature over the Arctic Ocean
A. Held,D. A. Orsini,P. Vaattovaara,M. Tjernstr?m
Atmospheric Measurement Techniques Discussions , 2011, DOI: 10.5194/amtd-4-3017-2011
Abstract: Temperature and particle number concentration profiles were measured at small height intervals above open and frozen leads and snow surfaces in the central Arctic. The device used was a gradient pole designed to investigate potential particle sources over the central Arctic Ocean. The collected data was fitted according to basic logarithmic flux-profile relationships to calculate the sensible heat flux and particle deposition velocity. Independent measurements by the eddy covariance technique were conducted at the same location. General agreement was observed between the two methods when logarithmic profiles could be fitted to the gradient pole data. In general, snow surfaces behaved as weak particle sinks with a maximum deposition velocity vd = 1.3 mm s 1 measured with the gradient pole. The lead surface behaved as a weak particle source before freeze-up with an upward flux Fc = 5.7 × 104 particles m 2 s 1, and as a relatively strong heat source after freeze-up, with an upward maximum sensible heat flux H = 13.1 W m 2. Over the frozen lead, however, we were unable to resolve any significant aerosol profiles.
Limits Due to Instrumental Polarisation in CMB Experiments at Microwave Wavelengths
E. Carretti,R. Tascone,S. Cortiglioni,J. Monari,M. Orsini
Physics , 2001, DOI: 10.1016/S1384-1076(01)00050-1
Abstract: An extended analysis of some instrumental polarisation sources has been done, as a consequence of the renewed interest in extremely sensitive polarisation measurements stimulated by Cosmic Microwave Background experiments. The case of correlation polarimeters, being them more suitable than other configurations, has been studied in detail and the algorithm has been derived to calculate their intrinsic sensitivity limit due to device characteristics as well as to the operating environment. The atmosphere emission, even though totally unpolarised, has been recognized to be the most important source of sensitivity degradation for ground based experiments. This happens through receiver component losses (mainly in the OMT), which generate instrumental polarisation in genuinely uncorrelated signals. The relevant result is that, also in best conditions (cfr. Antarctica), integration times longer than ~40s are not allowed on ground without modulation techniques. Finally, basic rules to estimate the maximum modulation period for each instrumental configuration have been provided.

Deregulating 'the rural'; threatening land management regime. Experiences of space in the Tuscan countryside
Stefano Orsini
Physics , 2011,
Abstract: In this research the relationships between landownership and the use of rural land are investigated and analyzed through an empirical study, conducted in Tuscany, which was based on interviews with landowners. Through the development of farmers' typologies, the results highlight a general process of decoupling from farming, which appears through 'disinvestments' in farming activity and changing the intended uses of rural land and buildings. The dynamic of liberalization (and urbanization) of rural space arises challenges to the future of land management system, which seems to be going to suffer a process of restructuring.
A Geometric Proof of Fermat’s Little Theorem  [PDF]
Thomas Beatty, Marc Barry, Andrew Orsini
Advances in Pure Mathematics (APM) , 2018, DOI: 10.4236/apm.2018.81004
Abstract: We present an intuitively satisfying geometric proof of Fermat's result for positive integers that \"\" for prime moduli p, provided p does not divide a. This is known as Fermat’s Little Theorem. The proof is novel in using the idea of colorings applied to regular polygons to establish a number-theoretic result. A lemma traditionally, if ambiguously, attributed to Burnside provides a critical enumeration step.

The angular power spectra of polarized Galactic synchrotron
M. Tucci,E. Carretti,S. Cecchini,R. Fabbri,M. Orsini,E. Pierpaoli
Physics , 2000, DOI: 10.1016/S1384-1076(00)00025-7
Abstract: We derive the angular power spectra of intensity and polarization of Galactic synchrotron emission in the range 36 < l < 10^3 from the Parkes survey mapping the southern Galactic plane at 2.4 GHz. The polarization spectra of both electric and magnetic parity up to l \simeq 10^3 are approximated very well by power laws with slope coefficients \simeq 1.4, quite different from the CMB spectra. We show that no problem should arise from Galactic synchrotron for measurements of CMB polarization in the cosmological window.
Bragg Grating Optical Filters by UV Nanoimprinting
M. Casalboni,L. Dominici,V. Foglietti,F. Michelotti,E. Orsini,C. Palazzesi,F. Stella,P. Prosposito
Journal of Nanomaterials , 2012, DOI: 10.1155/2012/186429
Abstract: Results on an optical waveguide filter operating in the near IR region are reported. The device consists of a hybrid sol-gel -based grating loaded waveguide, obtained through the merging of conventional photolithography and UV-nanoimprinting. Starting from submicrometric gratings, fabricated by electron beam lithography, a soft mould has been produced and the original structures were replicated onto sol-gel photosensitive films. A final photolithographic step allowed the production of grating-loaded channel waveguides. The devices were optically characterized by transmission measurements in the telecom range 1450–1590 nm. The filter extinction ratio is −11 dB and the bandwidth is 1.7 nm.
