Estratégias de crescimento e valor no mercado de fundos de investimento imobiliårios
TCC (graduação) - Universidade Federal de Santa Catarina. Centro Sócio-EconÎmico. Economia.O presente estudo buscou avaliar o desempenho de duas estratégias diferentes em Fundos de
Investimento ImobiliĂĄrios (FIIs), com a finalidade de observar a existĂȘncia da Value Premium
no mercado de FIIs. Precisamente, a anĂĄlise empĂrica se deu atravĂ©s de carteiras quadrimestrais,
estabelecidas atravĂ©s do ranqueamento dos ativos pelo Ăndice P/VPA e classificando-as como
Valor (baixa razĂŁo P/VPA) e Crescimento (alta razĂŁo P/VPA) durante o perĂodo de 2013 a 2018
na bolsa de valores brasileira. Os resultados indicam uma prevalĂȘncia risco-retorno previsto no
CAPM apontando, desta forma, a inexistĂȘncia da Value Premium para esta categoria de
investimento. Contudo, Ă© vĂĄlido ressaltar que sĂŁo necessĂĄrios maiores estudos na ĂĄrea, visando
compreender as particularidades dos FIIs em relação ao resto do mercado

Role of Stem Cells and Extracellular Matrix in the Regeneration of Skeletal Muscle
Adult skeletal muscle has a remarkable capacity to initiate a rapid and extensive repair process after damage due to injury or degenerative disease. Although satellite cells are the primary skeletal muscle stem cells, there are many reports of non-satellite cell populations with myogenic capacity resident within skeletal muscle. The activity of muscle-resident stem cells during the regeneration process is tightly controlled through the dynamic interactions between intrinsic factors within the cells and extrinsic factors constituting the muscle stem cell niche. The extracellular matrix (ECM) in skeletal muscle plays an integral role in force transmission, structural maintenance, and regulation of stem cell niche. ECM interacts with stem cells either directly by binding cell surface receptors or indirectly through growth factor presentation, and maintains a balance between their quiescence, self-renewal, and differentiation. These interactions are reciprocal since the stem cells can remodel the niche and secrete or degrade ECM components. Natural ECM scaffolds, derived from decellularized tissues can influence stem cell activity both in vitro and in vivo and are widely being investigated for skeletal muscle repair. In this chapter, we discuss the regenerative potential of stem cell populations and ECM bioscaffolds in the treatment of skeletal muscle injury and disease
A Letter of Intent to Install a milli-charged Particle Detector at LHC P5
In this LOI we propose a dedicated experiment that would detect
"milli-charged" particles produced by pp collisions at LHC Point 5. The
experiment would be installed during LS2 in the vestigial drainage gallery
above UXC and would not interfere with CMS operations. With 300 fb of
integrated luminosity, sensitivity to a particle with charge
can be achieved for masses of GeV,
and charge for masses of GeV,
greatly extending the parameter space explored for particles with small charge
and masses above 100 MeV.Comment: 19 pages, 7 figure
Videolaparoscopic Radical Hysterectomy Approach: a Ten-Year Experience
Videolaparoscopic radical hysterectomy was found to have comparable operative times, lymph node retrieval, and complications as those reported by others
A 2.4 - 12 microns spectrophotometric study with ISO of Cygnus X-3 in quiescence
We present mid-infrared spectrophotometric results obtained with the ISO on
the peculiar X-ray binary Cygnus X-3 in quiescence, at orbital phases 0.83 to
1.04. The 2.4-12 microns continuum radiation observed with ISOPHOT-S can be
explained by thermal free-free emission in an expanding wind with, above 6.5
microns, a possible additional black-body component with temperature T ~ 250 K
and radius R ~ 5000 solar radii at 10 kpc, likely due to thermal emission by
circumstellar dust. The observed brightness and continuum spectrum closely
match that of the Wolf-Rayet star WR 147, a WN8+B0.5 binary system, when
rescaled at the same 10 kpc distance as Cygnus X-3. A rough mass loss estimate
assuming a WN wind gives ~ 1.2 10^{-4} M(sun)/yr. A line at ~ 4.3 microns with
a more than 4.3 sigma detection level, and with a dereddened flux of 126 mJy,
is interpreted as the expected He I 3p-3s line at 4.295 microns, a prominent
line in the WR 147 spectrum. These results are consistent with a
Wolf-Rayet-like companion to the compact object in Cygnus X-3 of WN8 type, a
later type than suggested by earlier works.Comment: 8 pages, 10 figures ; Accepted in A&
Aggregation and Representation in the European Parliament Party Groups
While members of the European Parliament are elected in national constituencies, their votes are determined by the aggregation of MEPs in multinational party groups. The uncoordinated aggregation of national party programmes in multinational EP party groups challenges theories of representation based on national parties and parliaments. This article provides a theoretical means of understanding representation by linking the aggregation of dozens of national party programmes in different EP party groups to the aggregation of groups to produce the parliamentary majority needed to enact policies. Drawing on an original data source of national party programmes, the EU Profiler, the article shows that the EP majorities created by aggregating MEP votes in party groups are best explained by cartel theories. These give priority to strengthening the EPâs collective capacity to enact policies rather than voting in accord with the programmes they were nationally elected to represent
ISO continuum observations of quasars at z=1-4 I.Spectral energy distributions of quasars from the UV to far-infrared
Eight luminous quasars with at z = 1.4 - 3.7 have been
observed in the mid- and far-infrared using ISO. All the quasars have been
detected in the mid-infrared bands of ISOCAM, while no far-infrared detections
have been made with ISOPHOT. Supplementing ISO observations with photometry in
the optical and near-infrared made from the ground mostly within 17 months
after the ISO observations, SEDs (Spectral Energy Distributions) from the UV to
far-infrared have been obtained. SEDs (Spectral Energy Distributions) from the
UV to far-infrared have been obtained while supplementing ISO observations with
photometry in the optical and near-infrared made from the ground within 17
months. The SEDs are compared with the MED (Mean spectral Energy Distributions)
of low-redshift quasars with . It is shown that our
far-infrared observations were limited by confusion noise due to crowded
sources.Comment: 9 pages, 3 figures: accepted for publication in Astronomy and

Transmission routes of African swine fever virus to domestic pigs: current knowledge and future research directions
African swine fever (ASF) is a major threat to the pig industry in Europe. Since 2007, ASF outbreaks have been ongoing in the Caucasus, Eastern Europe and the Baltic countries, causing severe economic losses for many pig farmers and pork producers. In addition, the number of ASF cases in wild boar populations has dramatically increased over the past few years. Evidence supports direct contact with infectious domestic pigs and wild boars, and consumption of contaminated feed, as the main transmission routes of ASF virus (ASFV) to domestic pigs. However, significant knowledge gaps highlight the urgent need for research to investigate the dynamics of indirect transmission via the environment, the minimal infective doses for contaminated feed ingestion, the probability of effective contacts between infectious wild boars and domestic pigs, the potential for recovered animals to become carriers and a reservoir for transmission, the potential virus persistence within wild boar populations and the influence of human behaviour for the spread of ASFV. This will provide an improved scientific basis to optimise current interventions and develop new tools and strategies to reduce the risk of ASFV transmission to domestic pigs.ISSN:0042-490
Double layer SiO2âTiO2 solâgel thin films on glass for antireflection, antifogging, and UV recoverable self-cleaning
Double layer thin films, mechanically stable and adhering to glass, were produced through the solâgel process, using tetraethyl orthosilicate and titanium butoxide as precursors. The refractive index of the titania and silicaâ titania composite layers were typically 2.1 and 1.7, and their physical thicknesses were approximately 65 nm and 81 nm, respectively, as determined by ellipsometry. These optical constants allowed attainment of quarterwave optical thicknesses at the center of the visible spectrum (550 nm) as designed, with an increase of 3.4% in transmittance. The nanometric surface roughness, measured by optical profilometry, was effective to decrease light scattering and water contact angles to below 10⊠. As novelty in dip-coated solâgel films, superhydrophilicity for self-cleaning, antifogging, and antireflection in the mid-visible spectrum were simultaneously attained with durability of 9 weeks in the dark. Further application of UV light allowed regeneration of contact angles for self-cleaning
