Snorkeling adalah salah satu hobu yang sangat digemari saat ini. Snorkeling sering di lakukan untuk refreshing sambil menyegarkan pikiran setelah berkutat dengan aktifitas dan pekerjaan yang menguras pikiran. Piranti atau (peralatan) snorkeling yang paling utama terdiri dari 4 alat yaitu, masker selam, baju selam, snorkel dan kaki katak atau sirip selam. Dalam penerapanya banyak kendala yang dihadapi para penyelam terutama dalam hal memilih piranti masih bersifat manual yaitu para penyelam hanya mendapat informasi dari instruktur snorkeling yang berada di kawasan snorkeling. Keadaan tersebut sudah pasti membuat proses pemilihan menjadi tidak efesien karena keterbatasan informasi yang bisa didapat sehingga perlunya dibuatkan sebuah sistem pendukung keputusan. Fuzzy C-means Clustering (FCM) adalah suatu teknik pengelompokan data yang mana keberadaan tiap-tiap titik dalam suatu cluster ditentukan oleh derajat keanggotaan. Pada penelitian ini akan digunakan metode perhitungan FCM untuk menentukan piranti yang tepat untuk direkomendasikan kepada User. Dengan adanya sistem pendukung keputusan dapat membantu user dalam memilih piranti yang sesuai dengan kriteria yang diinginkanya.
Integrating robotics into a minimally invasive transforaminal interbody fusion workflow
Authors: Snyder Laura A. 
Published: July 2018

Minimally invasive transforaminal lumbar interbody fusion (MIS TLIF) is a well-accepted procedure with good outcomes. Robotics has the potential to augment these outcomes. This video demonstrates and discusses how surgeons can implement the use of a robotic device in an MIS TLIF workflow. The planning software and robotic arm guidance allow the surgeon to use intraoperative CT to guide the placement of pedicle screws in an MIS TLIF with optimal trajectory and decreased radiation. As robotic technology continues to improve, developing safe workflows that integrate robotics with currently well-established techniques should improve patient outcomes.The video can be found here: https://youtu.be/rJWOa6XVLW0.

Published: July 2018

Resection of a giant pre-sacral schwannoma originating from the right S2 nerve in a 22-year-old woman illustrates the potential for robotic surgery. The da Vinci Robot Surgical System facilitates visualization deep in the pelvis and allows for bimanual wristed instrument control to dissect the tumor from surrounding sensitive structures. Neurostimulation to identify critical nerves is possible and complete resection of the tumor can be achieved. There were no complications, she remained neurologically intact, the estimated blood loss was less than 75 ml, the total hospital stay was 3 days, and she returned to work within 2 weeks of her operation. In select patients, robot-assisted surgery may have advantages.The video can be found here: https://youtu.be/SYjUA-WcyGI.
Is the Macronova in GW170817 Powered by the Central Engine?
Authors: Matsumoto Tatsuya , Ioka Kunihito , Kisaka Shota , Nakar Ehud 
Published: July 2018

Abstract
The gravitational wave event GW170817 from a binary neutron star merger is accompanied by electromagnetic counterparts, and the optical and near-infrared emission is called a macronova (or kilonova). Although the radioactivity of synthesized r-process elements is widely discussed as an energy source, its decisive evidence is not clearly shown yet. We discuss a macronova powered by central engine activities such as jet activities and X-rays from the matter fallback and show that the engine model allows much broader parameter spaces, in particular, smaller ejecta mass (

), than the r-process model. The blue and red macronovae are naturally explained by various combinations of the ejecta, such as a cocoon and merger ejecta with the energy sources of jets and X-rays. The required energy injection is very similar to the X-ray excess observed in GRB 130603B, with a power-law slope of

. The required lanthanoid fraction for the opacity can also be consistent with the Galactic one. Early or late multiwavelength observations are crucial for revealing the central engine of short gamma-ray bursts and the r-process nucleosynthesis.
Mg ii Line Properties in Lobe-dominated Quasars
Authors: Wildy Conor , Czerny Bozena , Kuźmicz Agnieszka 
Published: July 2018

Abstract
We investigate the relationships between Mg ii
λ2798 emission line properties, as well as between these properties and inclination angle and Fe ii strength, in a lobe-dominated quasar sample. We find no correlation between Mg ii line width and inclination, unlike previous studies of the general quasar population. This suggests that the Mg ii emission region in these objects is not of a thin disk geometry; however, the average equivalent width (EW) of the line negates a spherical alternative. A positive correlation between Mg ii EW and inclination cannot be ruled out, meaning there is no strong evidence that Mg ii emission is anisotropic. Since thin disk emission would be highly directional, the geometric implications of these two findings are compatible. The lack of line width correlation with inclination may also indicate that Mg ii is useful for estimating black hole masses in lobe-dominated quasar samples, since it is unbiased by orientation. Some quasars in our sample have almost edge-on viewing angles and therefore cannot have a smooth toroidal obscurer co-planar with the accretion disk. Alternatives may be a distorted dusty disk or a clumpy obscurer. This could result from the sample selection bias toward high inclination objects, rather than intrinsic differences between lobe-dominated and typical quasars. Five objects have visible [O iii], allowing EW calculation and revealing it to be higher than in typical quasars. Since these objects are of high inclination, this finding supports the positive correlation between [O iii] EW and inclination found in a previous study.

Abstract
We perform a suite of smoothed particle hydrodynamics simulations to investigate in detail the results of a giant impact on the young Uranus. We study the internal structure, rotation rate, and atmospheric retention of the post-impact planet, as well as the composition of material ejected into orbit. Most of the material from the impactor’s rocky core falls in to the core of the target. However, for higher angular momentum impacts, significant amounts become embedded anisotropically as lumps in the ice layer. Furthermore, most of the impactor’s ice and energy is deposited in a hot, high-entropy shell at a radius of ∼3 R
⊕. This could explain Uranus’ observed lack of heat flow from the interior and be relevant for understanding its asymmetric magnetic field. We verify the results from the single previous study of lower resolution simulations that an impactor with a mass of at least 2 M
⊕ can produce sufficiently rapid rotation in the post-impact Uranus for a range of angular momenta. At least 90% of the atmosphere remains bound to the final planet after the collision, but over half can be ejected beyond the Roche radius by a 2 or 3 M
⊕ impactor. This atmospheric erosion peaks for intermediate impactor angular momenta (∼3 × 1036 kg m2 s−1). Rock is more efficiently placed into orbit and made available for satellite formation by 2 M
⊕ impactors than 3 M
⊕ ones, because it requires tidal disruption that is suppressed by the more massive impactors.

Abstract
We present a study of the H i gas content of a large K-band-selected sample of 88 close major-merger pairs of galaxies (H-KPAIR) that were observed by Herschel. We obtained the 21 cm H i fine-structure emission-line data for a total of 70 pairs from this sample, by observing 58 pairs using the Green Bank Telescope (GBT) and retrieving the H i data for an addition 12 pairs from the literature. In this H i sample, 34 pairs are spiral–spiral (S+S) pairs, and 36 are spiral–elliptical (S+E) pairs. Based on these data, we studied the H i-to-stellar mass ratio, the H i gas fraction, and the H i star formation efficiency (SFEH i
= star-formation-rate/M
H i
) and searched for differences between S+S and S+E pairs, as well as between pairs with and without signs of merger/interaction. Our results showed that the mean H i-to-stellar mass ratio of spirals in these pairs is =7.6 ± 1.0%, consistent with the average H i gas fraction of spiral galaxies in general. The differences in the H i gas fraction between spirals in S+S and in S+E pairs, and between spirals in pairs with and without signs of merger/interaction, are insignificant (<1σ). On the other hand, the mean SFEH i
of S+S pairs is ∼4.6× higher than that of S+E pairs. This difference is very significant (∼4σ) and is the main result of our study. There is no significant difference in the mean SFEH i
between galaxies with and without signs of merger/interaction. The mean SFEH i
of the whole pair sample is 10−9.55±0.09 yr−1, corresponding to a H i consumption time of 3.5 ± 0.7 Gyr.
La Maison de Salomon
Authors: Ruellet Aurélien 
Published: July 2018

La Maison de Salomon est le nom que donne l'homme d'État anglais Francis Bacon à l'institution imaginaire décrite dans son récit utopique La Nouvelle Atlantide : une confrérie dont les membres s'efforcent de mettre les sciences, les inventions et les techniques au service du bien commun. L'idée est puissamment mobilisatrice et constitue l'un des moteurs, quelques décennies plus tard, de la création des académies scientifiques française et anglaise. Mais cette « maison » existe déjà quand paraît en 1627 l'utopie baconienne. Elle est constituée de tous ceux, inventeurs, professeurs, fabricants d'instruments mathématiques, libraires spécialisés ou ingénieurs qui font des sciences et techniques leur occupation. Comment vivre de son savoir lorsqu'on n'était pas gentilhomme comme Descartes ? Quelles opportunités se présentaient à ceux qui, de part et d'autre de la Manche, cultivaient les sciences et les techniques ? Quelle place leur réservaient des sociétés d'Ancien Régime qu'on croit souvent, avec quelque raison, rétives ou étrangères à la rationalité scientifique moderne ? Comment et par qui ces hommes étaient-ils protégés ? Loin de l'image classique du mécénat aristocratique et royal, cette enquête montre que le patronage dont ils bénéficiaient revêtait bien des aspects et mobilisait de nombreux mécènes au petit pied, dans l'administration monarchique et ailleurs.En revenant sur les carrières de dizaines de savants et techniciens français et anglais du xviie siècle, cet ouvrage éclaire ainsi des aspects méconnus de la formation de l'État moderne et de l'émergence de la science expérimentale.
Cutting Edge: Critical Roles for Microbiota-Mediated Regulation of the Immune System in a Prenatal Immune Activation Model of Autism

Abstract
Recent studies suggest that autism is often associated with dysregulated immune responses and altered microbiota composition. This has led to growing speculation about potential roles for hyperactive immune responses and the microbiome in autism. Yet how microbiome–immune cross-talk contributes to neurodevelopmental disorders currently remains poorly understood. In this study, we report critical roles for prenatal microbiota composition in the development of behavioral abnormalities in a murine maternal immune activation (MIA) model of autism that is driven by the viral mimetic polyinosinic-polycytidylic acid. We show that preconception microbiota transplantation can transfer susceptibility to MIA-associated neurodevelopmental disease and that this is associated with modulation of the maternal immune response. Furthermore, we find that ablation of IL-17a signaling provides protection against the development of neurodevelopmental abnormalities in MIA offspring. Our findings suggest that microbiota landscape can influence MIA-induced neurodevelopmental disease pathogenesis and that this occurs as a result of microflora-associated calibration of gestational IL-17a responses.

Interpreting Machiavelli's Tribunes of the Plebs
Authors: Barthas Jérémie 
Published: July 2018

Abstract
In the last thirty years, the “aristocratic” current of the republican tradition of thought has seen a revival largely based on a reinterpretation of Niccolò Machiavelli's contribution. Quite recently, this reinterpretation was challenged by emphasizing the fundamentaly “anti-aristocratic” and radically “democratic” nature of Machiavelli's thinking. After John McCormick's Machiavellian Democracy (2011), Lawrence Hamilton's Freedom Is Power (2014) is the latest attempt to engage critically with both interpretive currents and to offer institutional solutions for the ongoing crisis of representation in liberal democracies, most notably by proposing to update the ancient institution of the tribunes of the plebs. In this article I discuss McCormick and Hamilton's interpretation of Machiavelli's tribunician function, and bring into the debate an examination of Florentine institutions and of Machiavelli's constitutional draft of 1522 (not yet published in English).
Preliminary analysis of New Zealand scampi (Metanephrops challengeri) diet using metabarcoding
Authors: van der Reis Aimee L , Laroche Olivier , Jeffs Andrew G , Lavery Shane D 
Published: July 2018

Deep sea lobsters are highly valued for seafood and provide the basis of important commercial fisheries in many parts of the world. Despite their economic significance, relatively little is known about their natural diets. Microscopic analyses of foregut content in some species have suffered from low taxonomic resolution, with many of the dietary items difficult to reliably identify as their tissue is easily digested. DNA metabarcoding has the potential to provide greater taxonomic resolution of the diet of the New Zealand scampi (Metanephrops challengeri) through the identification of gut contents, but a number of methodological concerns need to be overcome first to ensure optimum DNA metabarcoding results.
In this study, a range of methodological parameters were tested to determine the optimum protocols for DNA metabarcoding, and provide a first view of M. challengeri diet. Several PCR protocols were tested, using two universal primer pairs targeting the 18S rRNA and COI genes, on DNA extracted from both frozen and ethanol preserved samples for both foregut and hindgut digesta.
The selection of appropriate DNA polymerases, buffers and methods for reducing PCR inhibitors (including the use of BSA) were found to be critical. Amplification from frozen or ethanol preserved gut contents appeared similarly dependable, but metabarcoding outcomes indicated that the ethanol samples produced better results from the COI gene. The COI gene was found to be more effective than 18S rRNA gene for identifying large eukaryotic taxa from the digesta, however, it was less successfully amplified. The 18S rRNA gene was more easily amplified, but identified mostly smaller marine organisms such as plankton and parasites. This preliminary analysis of the diet of M. challengeri identified a range of species (13,541 reads identified as diet), which included the ghost shark (Hydrolagus novaezealandiae), silver warehou (Seriolella punctate), tall sea pen (Funiculina quadrangularis) and the salp (Ihlea racovitza), suggesting that they have a varied diet, with a high reliance on scavenging a diverse range of pelagic and benthic species from the seafloor.
Genetic population structure of the pelagic mollusk Limacina helicina in the Kara Sea

Published: July 2018

Background. Pelagic pteropods Limacina helicina are widespread and can play an important role in the food webs and in biosedimentation in Arctic and Subarctic ecosystems. Previous publications have shown differences in the genetic structure of populations of L. helicina from populations foundin the Pacific Ocean and Svalbard area. Currently, there are no data on the genetic structure of L. helicina populations in the seas of the Siberian Arctic. We assessed the genetic structure of L. helicina from the Kara Sea populations and compared them with samples from around Svalbard and the North Pacific. We also compared L. helicina from the different habitats within the Kara Sea.
Methods. We examined genetic differences in L. helinica from three different locations in the Kara Sea via analysis of a fragment of the mitochondrial gene COI. We also compared a subset of samples with L. helicina from previous studies to find connections between populations from the Atlantic and Pacific Oceans.
Results. 65 individual L. helinica from the Kara Sea were sequenced to produce 19 different haplotypes. This is comparable with numbers of haplotypes found in Svalbard and Pacific samples (24 and 25, respectively). Haplotypes from different locations sampled around Arctic and Subarctic were combined into two significantly different groups: H1 and H2. The H2 includes sequences from the Kara Sea and Svalbard, was present only in the Atlantic sector of the Arctic. The other genetic group, H1, is widespread and found throughout all L. helicina populations. Phi-st analyses also indicated significant genetic difference between the Atlantic and Pacific regions, but no differences between Svalbard and the Kara Sea.
Discussion. The obtained results support our hypothesis about genetic similarity of L. helicina populations from the Kara Sea and Svalbard: the majority of haplotypes belongs to the haplotype group H2, with the H1 group representing a minority of the haplotypes present. In contrast, in the Canadian Arctic and the Pacific Ocean only haplogroup H1 is found. The negative values of Fu's Fs indicate directed selection or expansion of the population. The reason for this pattern could be due to an isolation of the Limacina helicina population during the Pleistocene glaciation and a subsequent rapid expansion of this species after the last glacial maximum.
High Propylene Selective Metal‐Organic Framework Membranes Prepared in Confined Spaces via Convective Circulation Synthesis
Authors: Huang Kang , Wang Bo , Chi Yunsi , Li Kang 
Published: July 2018

AbstractIn this study, the successful preparation of defect‐free metal‐organic framework (MOF) membranes on the inner surface of ceramic hollow fibers and micromonoliths is reported for the first time. The prepared zeolitic imidazolite framework‐8 membranes exhibit impressively high propylene/propane (C3H6/C3H8) separation factor (up to 139), which is over an order of magnitude higher than that of traditional polymeric membranes. Such excellent results are achieved via a versatile convective circulation method, which eliminates the need of pumps for materials supply and is cost effective andenergy efficient. The MOF membranes prepared in this study show the potential in meeting stringent industrial requirements, as they have full protection from external impact during storage and module assembly, as well as high membrane surface area per volume, enabling compact devices for process intensification.
Bimetallic Network with Hetero‐interfacial Plasmons
Authors: Zhang Jian , Zhang Xinping 
Published: June 2018

AbstractFabrication of bimetallic networks consisting of periodically arranged gold nanoparticles (AuNPs) embedded with a grid of silver nanowires, where solution‐processing materials or techniques are involved in all of the fabrication procedures, is reported. Annealing of the colloidal gold nanoparticles and the photoreduction of the silver ions in the mixture solution of AgNO3 and polyvinyl pyrrolidone in water are the main processes. The key to this fabrication is that the AuNP array is used as the mask for the photoreduction of silver ions into nanowires, where the silver nanowires are thus located between the AuNPs. Two sets of dipolar and quadrupolar plasmons, as well as their respectively coupled resonance modes, are observed in the measurements and specified using theoretical analysis. Thus, the bimetallic photonic structures not only show enhanced and extended resonance spectrum due to the overlap of multiple localized surface plasmons but also induce plasmonic hetero‐interfacial interaction between the closely adjacent AuNPs and silver nanowires.
