Código Penal: Alteração e implementação do crime contra a liberdade sexual, artigo 215-A
O artigo vem demonstrar as alterações e implementações dos crimes contra a liberdade sexual. No Código Penal Brasileiro o estupro é considerado um crime hediondo, devido à alta gravidade do delito. Traça uma linha do tempo para chegar à atualização recente que ocorreu no código penal, com a lei de n° 13.718 de setembro de 2018. Essa lei em destaque no artigo, tipifica os crimes de importunação sexual, antes previsto no Art. 61 da lei de contravenções penais, e sobre a divulgação de cenas de estupro. Antes da alteração, o agente era enquadrado ou no crime de estupro (alta gravidade) ou na contravenção penal (menor gravidade), faltando um delito para prescrever casos em que foram notícias nos jornais nos últimos anos: assédio sexual dentro do transporte coletivo. Poderá ser encaixado no delito de importunação sexual, os beijos forçados, passadas de mão indesejadas e outros atos que a vítima não teve o consentimento para tal ocorrência, mas também não teve violência para encaixar-se no crime de estupro. A importunação sexual é um crime subsidiário, criado para eliminar a lacuna na lei que anteriormente existia, para conseguir adequar casos recentes que ocorre na sociedade
Spatially resolved observations of outflows in the radio loud AGN of UGC 8782
We use optical Integral Field Spectroscopy (IFU) to study the gas emission
structure and kinematics in the inner 3.44.9 kpc region of the
galaxy UGC 8782 (3C 293), host of a radio loud Active Galactic Nucleus (AGN).
The observations were performed with the GMOS-IFU on the Gemini North
telescope, resulting in a spatial resolution of pc at the distance of
the galaxy. While the stars present ordered rotation following the orientation
of the large scale disc, the gas shows a disturbed kinematics. The
emission-line profiles present two kinematic components: a narrow
( km s) component associated with the gas in the disc
of the galaxy and a broad ( km s) component produced
by gas outflows. Emission-line ratio diagrams indicate that the gas in the disc
is excited by the AGN radiation field, while the emission of the outflow
includes additional contribution of shock excitation due to the interaction of
the radio jet with the environment gas. Deviations from pure rotation, of up to
30 km s, are observed in the disc component and likely produced by a
previous merger event. The broad component is blueshifted by km
s relative to the systemic velocity of the galaxy in all locations. We
construct radial profiles of the mass outflow rate and kinetic power of the
ionized gas outflows, which have the maximum values at kpc from the
nucleus with peak values of M
yr and (6.81.1)10 erg
s. The kinetic coupling efficiency of these outflows is in the range of
13 per cent, indicating that they could be powerful enough to affect the
star formation in the host galaxy as predicted by theoretical simulations.Comment: Accepted for publication by MNRA
A Decade of Near-Infrared Variability in NGC4388: Insights into the AGN Structure
Variability studies have proven to be a powerful diagnostic tool for
understanding the physics and properties of of Active Galactic Nuclei (AGNs).
They provide insights into the spatial and temporal distribution of the
emitting regions, the structure and dynamics of the accretion disk, and the
properties of the central black hole. Here, we have analysed the K-band
spectral variability of the Seyfert 1.9/2 galaxy NGC4388 spanning five epochs
over a period of ten years. We have performed spectral synthesis of the nuclear
region and found that the contribution of warm dust (T~800K) declined by 88%
during these 10 years. In the same period, the [CaVIII] coronal line decreased
61%, whereas BrG emission declined 35%. For the HeI and H2, we did not detect
any significant variation beyond their uncertainties. Based on the time span of
these changes, we estimate that the region where the warm dust is produced is
smaller than 0.6pc, which suggests that this spectral feature comes from the
innermost part of the region sampled, directly from the AGN torus. On the other
hand, the bulk of [CaVIII] is produced in the inner ~2pc and the nuclear BrG
region is more extended, spanning a region larger than 3pc. Lastly, HeI and H2
are even more external, with most of the emission probably being produced in
the host galaxy rather than in the AGN. This is the first spectroscopic
variability study in the NIR for an AGN where the central source is not
directly visible.Comment: Accepted in MNRAS. 8 pages, 3 figure
Risk factors for epilepsy after thrombolysis for ischemic stroke : a cohort study
The effects of thrombolysis in seizure and epilepsy after acute ischemic stroke have been poorly explored. In this study, we examine risk factors and consequences of intravenous rt-PA for treatment of acute ischemic stroke. In a retrospective cohort study we evaluate risk factors for seizure and epilepsy after stroke thrombolysis, as well as the impact of seizures and epilepsy in outcome of stroke patients. In our cohort, mean age of patients was 67.2 years old (SD = 13.1) and 79 of them (51.6%) were male and. Initial NIHSS mean score were 10.95 (SD = 6.25). Three months NIHSS mean score was 2.09 (SD = 3.55). Eighty seven (56.9%) patients were mRS of 0–1 after thrombolysis. Hemorrhagic transformation was observed in 22 (14.4%) patients. Twenty-one (13.7%) patients had seizures and 15 (9.8%) patients developed epilepsy after thrombolysis. Seizures were independently associated with hemorrhagic transformation (OR = 3.26; 95% CI = 1.08–9.78; p = 0.035) and with mRS >= 2 at 3 months after stroke (OR = 3.51; 95% CI = 1.20–10.32; p = 0.022). Hemorrhagic transformation (OR = 3.55; 95% CI = 1.11–11.34; p = 0.033) and mRS >= 2 at 3 months (OR = 5.82; 95% CI = 1.45–23.42; p = 0.013) were variables independently associated with post-stroke epilepsy. In our study, independent risks factors for poor outcome in stroke thrombolysis were age (OR = 1.03; 95% CI = 1.01–1.06; p = 0.011), higher NIHSS (OR = 1.08; 95% CI = 1.03– 1.14; p = 0.001), hemorrhagic transformation (OR = 2.33; 95% CI = 1.11–4.76; p = 0.024), seizures (OR = 3.07; 95% CI = 1.22–7.75; p = 0.018) and large cortical area (ASPECTS <= 7) (OR = 2.04; 95% CI = 1.04–3.84; p = 0.036). Concluding, in this retrospective cohort study, the neurological impairment after thrombolysis (but not before) and hemorrhagic transformation remained independent risk factors for seizures or post-stroke epilepsy after thrombolysis. Moreover, we observed that seizures emerged as an independent risk factor for poor outcome after thrombolysis therapy in stroke patients (OR = 3.07; 95% CI = 1.22–7.75; p = 0.018)
Gemini NIFS survey of feeding and feedback in nearby active galaxies III. Ionized versus warm molecular gas masses and distributions
We have used the Gemini Near-Infrared Integral Field Spectrograph in the J and K bands to map the distribution, excitation, and kinematics of the ionized H ii and warm molecular gas H2, in the inner few 100 pc of six nearby active galaxies: NGC 788, Mrk 607, NGC 3227, NGC 3516, NGC 5506, NGC 5899. For most galaxies, this is the first time that such maps have been obtained. The ionized and H2 gas show distinct kinematics: while the H2 gas is mostly rotating in the galaxy plane with low velocity dispersion (σ), the ionized gas usually shows signatures of outflows associated with higher σ values, most clearly seen in the [Fe ii] emission line. These two gas species also present distinct flux distributions: the H2 is more uniformly spread over the whole galaxy plane, while the ionized gas is more concentrated around the nucleus and/or collimated along the ionization axis of its active galactic nucleus (AGN), presenting a steeper gradient in the average surface mass density profile than the H2 gas. The total H ii masses cover the range 2×105--2×107 M⊙, with surface mass densities in the range 3–150 M⊙ pc−2, while for the warm H2 the values are 103–4 times lower. We estimate that the available gas reservoir is at least ≈ 100 times more massive than needed to power the AGN. If this gas forms new stars the star formation rates, obtained from the Kennicutt–Schmidt scaling relation, are in the range 1–260 × 10−3 M⊙ yr−1. But the gas will also – at least in part – be ejected as the observed outflow

Gemini NIFS survey of feeding and feedback in nearby active galaxies : IV. Excitation
The near-infrared spectra of active galactic nuclei (AGN) present emission lines of different atomic and molecular species. The mechanisms involved in the origin of these emission lines in AGN are still not fully understood. We use J- and K-band integral field spectra of six luminous (43.1 < logLbol/(erg s−1) < 44.4) Seyfert galaxies (NGC 788, Mrk 607, NGC 3227, NGC 3516, NGC 5506, and NGC 5899) in the local Universe (0.0039 <z< 0.0136) to investigate the gas excitation within the inner 100–300 pc radius of the galaxies at spatial resolutions of a few tens of parsecs. In all galaxies, the H2 emission originates from thermal processes with excitation temperatures in the range 2400–5200 K. In the high-line ratio (HLR) region of the H2/Brγ versus [Fe II]/Paβ diagnostic diagram, which includes 29 per cent of the spaxels, shocks are the main excitation mechanism, as indicated by the correlation between the line widths and line ratios. In the AGN region of the diagram (64 per cent of the spaxels) the H2 emission is due to the AGN radiation. The [Fe II] emission is produced by a combination of photoionization by the AGN radiation and shocks in five galaxies and is dominated by photoionization in NGC 788. The [S IX]1.2523 μm coronal emission line is present in all galaxies, and its flux distributions are extended from 80 to 185 pc from the galaxy nuclei, except for NGC 5899, in which this line is detected only in the integrated spectrum
Gemini NIFS survey of feeding and feedback in nearby active galaxies V. Molecular and ionized gas kinematics
We study the gas distribution and kinematics of the inner kpc of six moderately luminous (43.43 ≤ log Lbol ≤ 44.83) nearby (0.004 ≤ z ≤ 0.014) Seyfert galaxies observed with the Near-infrared Integral Field Spectrograph (NIFS) in the J (1.25μm) and K (2.2μm) bands. We analyse the most intense emission lines detected on these spectral wavebands: [Fe ii] 1.2570μm and Paβ, which trace the ionized gas in the partially and fully ionized regions, and H2 2.1218μm, which traces the hot (∼2000 K) molecular gas. The dominant kinematic component is rotation in the disc of the galaxies, except for the ionized gas in NGC 5899 that shows only weak signatures of a disc component. We find ionized gas outflow in four galaxies, while signatures of H2 outflows are seen in three galaxies. The ionized gas outflows display velocities of a few hundred km s−1, and their mass outflow rates are in the range 0.005–12.49 M⊙ yr−1. Their kinetic powers correspond to 0.005–0.7 per cent of the active galactic nuclei (AGN) bolometric luminosities. Besides rotation and outflows signatures in some cases, the H2 kinematics also reveals inflows in three galaxies. The inflow velocities are 50–80 km s−1 and the mass inflow rates are in the range 1–9 × 10−4 M⊙ yr−1 for hot molecular gas. These inflows might be only the hot skin of the total inflowing gas, which is expected to be dominated by colder gas. The mass inflow rates are lower than the current accretion rates to the AGN, and the ionized outflows are apparently disturbing the gas in the inner kpc
