ABSTRACTRumpon or Fish Aggregating Devices (FADs) had been used by purse seine and handline fishermen in Pacitan Regency since 2005. The use of rumpon has been associated with the catching of immature fishes in large number that would disrupt the sustainability of fish resources. The aims of this study were to measure fishing productivity of purse seine and handline fleets operated around FADs deployed in eastern Indian Ocean waters and analyze the size distribution and gonad maturity index of the catch. This study was conducted at Tamperan Fishing Port of the Pacitan Regency, East Java Province. Daily fish landing data from both fishing fleets were collected from the Tamperan auction hall from January to December 2014 for productivity calculation. About 289 fish samples from 6 dominant species was taken randomly on-board of 3 purse seine and 2 handlines vessels from 8 different FADs for size distribution and gonad analysis. The average productivity of purse seine fleets in 2014were 6,7 tonnes/trip (s = 5 tonnes/trip) while handling fleets average productivity were 0,9 tons/trip (s = 0,6 tons/trip. Purse seine catch were dominated by immature and juvenile fish while handlines catch were larger and already mature fishes.Keywords:FADs, fishing productivity, gonad analysisABSTRAK Rumpon atau Fish Aggregating Devices (FADs) telah digunakan oleh nelayan pukat cincin dan pancing ulur di Kabupaten Pacitan sejak tahun 2005.

Abstract
For future human missions to Mars, it is important to study the surface radiation environment during extreme and elevated conditions. In the long term, it is mainly galactic cosmic rays (GCRs) modulated by solar activity that contribute to the radiation on the surface of Mars, but intense solar energetic particle (SEP) events may induce acute health effects. Such events may enhance the radiation level significantly and should be detected as immediately as possible to prevent severe damage to humans and equipment. However, the energetic particle environment on the Martian surface is significantly different from that in deep space due to the influence of the Martian atmosphere. Depending on the intensity and shape of the original solar particle spectra, as well as particle types, the surface spectra may induce entirely different radiation effects. In order to give immediate and accurate alerts while avoiding unnecessary ones, it is important to model and well understand the atmospheric effect on the incoming SEPs, including both protons and helium ions. In this paper, we have developed a generalized approach to quickly model the surface response of any given incoming proton/helium ion spectra and have applied it to a set of historical large solar events, thus providing insights into the possible variety of surface radiation environments that may be induced during SEP events. Based on the statistical study of more than 30 significant solar events, we have obtained an empirical model for estimating the surface dose rate directly from the intensities of a power-law SEP spectra.
Outcomes of Grazing Impacts between Sub-Neptunes in Kepler Multis

Abstract
Studies of high-multiplicity, tightly packed planetary systems suggest that dynamical instabilities are common and affect both the orbits and planet structures, where the compact orbits and typically low densities make physical collisions likely outcomes. Since the structure of many of these planets is such that the mass is dominated by a rocky core, but the volume is dominated by a tenuous gas envelope, the sticky-sphere approximation, used in dynamical integrators, may be a poor model for these collisions. We perform five sets of collision calculations, including detailed hydrodynamics, sampling mass ratios, and core mass fractions typical in Kepler Multis. In our primary set of calculations, we use Kepler-36 as a nominal remnant system, as the two planets have a small dynamical separation and an extreme density ratio. We use an N-body code, Mercury 6.2, to integrate initially unstable systems and study the resultant collisions in detail. We use these collisions, focusing on grazing collisions, in combination with realistic planet models created using gas profiles from Modules for Experiments in Stellar Astrophysics and core profiles using equations of state from Seager et al. to perform hydrodynamic calculations, finding scatterings, mergers, and even a potential planet–planet binary. We dynamically integrate the remnant systems, examine the stability, and estimate the final densities, finding that the remnant densities are sensitive to the core masses, and collisions result in generally more stable systems. We provide prescriptions for predicting the outcomes and modeling the changes in mass and orbits following collisions for general use in dynamical integrators.
J0815+4729: A Chemically Primitive Dwarf Star in the Galactic Halo Observed with Gran Telescopio Canarias*

Abstract
We report the discovery of the carbon-rich hyper metal-poor unevolved star J0815+4729. This dwarf star was selected from SDSS/BOSS as a metal-poor candidate and follow-up spectroscopic observations at medium resolution were obtained with the Intermediate dispersion Spectrograph and Imaging System (ISIS) at William Herschel Telescope and the Optical System for Imaging and low-intermediate-Resolution Integrated Spectroscopy (OSIRIS) at Gran Telescopio de Canarias. We use the FERRE code to derive the main stellar parameters,

is assumed. The metallicity upper limit is based on the Ca ii K line, which at the resolving power of the OSIRIS spectrograph cannot be resolved from possible interstellar calcium. The star could be the most iron-poor unevolved star known and also be among the ones with the largest overabundances of carbon. High-resolution spectroscopy of J0815+4729 will certainly help to derive other important elemental abundances, possibly providing new fundamental constraints on the early stages of the universe, the formation of the first stars, and the properties of the first supernovae.
Black Hole Formation and Fallback during the Supernova Explosion of a 40 M⊙ Star

Published: January 2018

Abstract
Fallback in core-collapse supernovae is considered a major ingredient for explaining abundance anomalies in metal-poor stars and the natal kicks and spins of black holes (BHs). We present a first 3D simulation of BH formation and fallback in an “aborted” neutrino-driven explosion of a 40 solar mass zero-metallicity progenitor from collapse to shock breakout. We follow the phase up to BH formation using the relativistic CoCoNuT-FMT code. For the subsequent evolution to shock breakout we apply the moving-mesh code Arepo to core-collapse supernovae for the first time. Our simulation shows that despite early BH formation, neutrino-heated bubbles can survive for tens of seconds before being accreted, leaving them sufficient time to transfer part of their energy to sustain the shock wave as is propagates through the envelope. Although the initial net energy (∼2 Bethe) of the neutrino-heated ejecta barely equals the binding energy of the envelope,

of hydrogen are still expelled with an energy of 0.23 Bethe. We find no significant mixing and only a modest BH kick and spin, but speculate that stronger effects could occur for slightly more energetic explosions or progenitors with less tightly bound envelopes.
Extending Counter-streaming Motion from an Active Region Filament to a Sunspot Light Bridge

Published: January 2018

Abstract
We analyze high-resolution observations from the 1.6 m telescope at Big Bear Solar Observatory that cover an active region filament. Counter-streaming motions are clearly observed in the filament. The northern end of the counter-streaming motions extends to a light bridge, forming a spectacular circulation pattern around a sunspot, with clockwise motion in the blue wing and counterclockwise motion in the red wing, as observed in the Hα off-bands. The apparent speed of the flow is around 10–60 km s−1 in the filament, decreasing to 5–20 km s−1 in the light bridge. The most intriguing results are the magnetic structure and the counter-streaming motions in the light bridge. Similar to those in the filament, the magnetic fields show a dominant transverse component in the light bridge. However, the filament is located between opposed magnetic polarities, while the light bridge is between strong fields of the same polarity. We analyze the power of oscillations with the image sequences of constructed Dopplergrams, and find that the filament’s counter-streaming motion is due to physical mass motion along fibrils, while the light bridge’s counter-streaming motion is due to oscillation in the direction along the line-of-sight. The oscillation power peaks around 4 minutes. However, the section of the light bridge next to the filament also contains a component of the extension of the filament in combination with the oscillation, indicating that some strands of the filament are extended to and rooted in that part of the light bridge.
1I/‘Oumuamua as a Tidal Disruption Fragment from a Binary Star System
Authors: Ćuk Matija 
Published: January 2018

Abstract
1I/‘Oumuamua is the first known interstellar small body, probably being only about 100 m in size. Against expectations based on comets, ‘Oumuamua does not show any activity and has a very elongated figure, and it also exhibits undamped rotational tumbling. In contrast, ‘Oumuamua’s trajectory indicates that it was moving with the local stars, as expected from a low-velocity ejection from a relatively nearby system. Here, I assume that ‘Oumuamua is typical of 100 m interstellar objects and speculate on its origins. I find that giant planets are relatively inefficient at ejecting small bodies from inner solar systems of main-sequence stars, and that binary systems offer a much better opportunity for ejections of non-volatile bodies. I also conclude that ‘Oumuamua is not a member of a collisional population, which could explain its dramatic difference from small asteroids. I observe that 100 m small bodies are expected to carry little mass in realistic collisional populations and that occasional events, when whole planets are disrupted in catastrophic encounters, may dominate the interstellar population of 100 m fragments. Unlike the Sun or Jupiter, red dwarf stars are very dense and are capable of thoroughly tidally disrupting terrestrial planets. I conclude that ‘Oumuamua may have originated as a fragment from a planet that was tidally disrupted and then ejected by a dense member of a binary system, which could explain its peculiarities.

Published: January 2018

Abstract
Background: Palliative radiotherapy (PRT) plays a significant role in the palliation of symptoms in patients with cancer and constitutes nearly 50% of the workload in different settings. Aims: The aim is to study patient-, disease-, and treatment-related characteristics in locoregionally advanced and metastatic malignancies meriting palliative management. Setting and Design: This was a retrospective observational study in a tertiary care government institute with academic and research potential. Methodology: The electronic medical records, medical documents, and radiotherapy (RT) treatment charts were retrieved and studied. Observations: A total of 460 patients were included in the study over 2 years, forming 30% of the total number of patients treated during the study period. Three hundred and ninety-six patients received PRT to the metastatic sites, while 64 patients received extremely hypofractionated PRT to the primary for symptomatic relief. Totally 442 patients showed good symptomatic response to PRT. One hundred and thirty-eight patients underwent re-irradiation. Lung was the most common primary site seen in 155 cases. The most common indication for PRT was palliation of pain from painful metastases as seen in 240 cases, and the next common indication was palliative whole-brain RT for brain metastases as seen in 159 cases. Conclusion: PRT forms an integral and important aspect of palliative care to the vast number of patients harboring metastatic disease that warrants some form of treatment for symptomatic relief. Short course of PRT in outdoor setting is a preferred mode of treatment to improve the quality of life of these distressed patients.

Abstract
Background: Retinoblastoma (Rb) is the most common primary intraocular tumor of infancy and childhood. Survivors' ocular and visual problems and increased risk for subsequent malignancy are well documented, but data on long-term health status of Rb survivors are limited, this being particularly true for India. Methodology: Children who had completed treatment for Rb at least 2 years ago before and were under follow-up at the after cancer treatment clinic were evaluated. Results: In our series of 213 patients, the median age was 29 months, there was a male preponderance, and majority had unilateral disease. Enucleation was done in almost three-fourth and 3% underwent bilateral enucleation. Majority of the patients received chemotherapy, and few received radiation. Growth was affected in about one-third and majority were those who had received radiation. Diminished vision was noticed in about one-sixth. Orbital hypoplasia and contracted socket were seen in 14.1% cases. 2.7% were hearing impaired. About one-sixth had a global intelligence delay. Second neoplasms were seen in 0.01%. No other abnormalities were seen. Conclusions: Common late effects in our Rb survivors include diminished vision in the salvage eye, intellectual disability, and contracted socket; there is a need for timely institution of prosthesis to avoid late effects such as hypoplasia, contracted sockets, and better cosmesis and enhanced self-esteem. Second neoplasm is a concern. Lifelong follow-up and counseling of a healthy lifestyle are needed for Rb survivors.
