Abstract
We present high angular resolution dust polarization and molecular line observations carried out with the Atacama Large Millimeter/submillimeter Array (ALMA) toward the Class 0 protostar Serpens SMM1. By complementing these observations with new polarization observations from the Submillimeter Array (SMA) and archival data from the Combined Array for Research in Millimeter-wave Astronomy (CARMA) and the James Clerk Maxwell Telescopes (JCMT), we can compare the magnetic field orientations at different spatial scales. We find major changes in the magnetic field orientation between large (∼0.1 pc) scales—where the magnetic field is oriented E–W, perpendicular to the major axis of the dusty filament where SMM1 is embedded—and the intermediate and small scales probed by CARMA (∼1000 au resolution), the SMA (∼350 au resolution), and ALMA (∼140 au resolution). The ALMA maps reveal that the redshifted lobe of the bipolar outflow is shaping the magnetic field in SMM1 on the southeast side of the source; however, on the northwestern side and elsewhere in the source, low-velocity shocks may be causing the observed chaotic magnetic field pattern. High-spatial-resolution continuum and spectral-line observations also reveal a tight (∼130 au) protobinary system in SMM1-b, the eastern component of which is launching an extremely high-velocity, one-sided jet visible in both

) and

); however, that jet does not appear to be shaping the magnetic field. These observations show that with the sensitivity and resolution of ALMA, we can now begin to understand the role that feedback (e.g., from protostellar outflows) plays in shaping the magnetic field in very young, star-forming sources like SMM1.
Relativistic Shear Flow between Electron–Ion and Electron–Positron Plasmas and Astrophysical Applications
Authors: Liang Edison , Fu Wen , Böttcher Markus 
Published: September 2017

Abstract
We present particle-in-cell simulation results of relativistic shear boundary layers between electron–ion and electron–positron plasmas and discuss their potential applications to astrophysics. Specifically, we find that in the case of a fast electron–positron spine surrounded by a slow-moving or stationary electron–ion sheath, lepton acceleration proceeds in a highly anisotropic manner due to electromagnetic fields created at the shear interface. While the highest-energy leptons still produce a beaming pattern (as seen in the quasi-stationary frame of the sheath) of order 1/Γ, where Γ is the bulk Lorentz factor of the spine, for lower-energy particles, the beaming is much less pronounced. This is in stark contrast to the case of pure electron–ion shear layers, in which anisotropic particle acceleration leads to significantly narrower beaming patterns than 1/Γ for the highest-energy particles. In either case, shear-layer acceleration is expected to produce strongly angle-dependent lepton (hence, emanating radiation) spectra, with a significantly harder spectrum in the forward direction than viewed from larger off-axis angles, much beyond the regular Doppler boosting effect from a co-moving isotropic lepton distribution. This may solve the problem of the need for high (and apparently arbitrarily chosen) minimum Lorentz factors of radiating electrons, often plaguing current blazar and GRB jet modeling efforts.

In the Triglav Mountains, mainly on the slopes and plateaus to the west of Mt. Triglav (Glava v Zaplanji, Vrh Zelenic) we found new localities of three rare species of Slovenian flora, Crepis terglouensis, Cerastium uniflorum and Geum reptans, and made a phytosociological inventory of their sites. Based on comparisons with similar communities within which they occur elsewhere in the Eastern and Southeastern Alps we described two new associations, Crepido terglouensis-Potentilletum nitidae (alliance Thlaspion rotundifolii) and Saxifrago carniolicae-Cerastietum uniflorae (alliance Arabidion caeruleae). Key words: Alpine flora, phytosociology, synsystematics, Crepis terglouensis, Cerastium uniflorum, Geum reptans, Triglav National Park, Slovenia V Triglavskem pogorju, predvsem na pobočjih in planotah zahodno od Triglava (Glava v Zaplanji, Vrh Zelenic) smo našli nova nahajališča treh redkih vrst v flori Sloveniji, Crepis terglouensis, Cerastium uniflorum in Geum reptans in fitocenološko popisali njihova rastišča. Na podlagi primerjav s podobnimi združbami, v katerih uspevajo omenjene vrste drugod v Vzhodnih in Jugovzhodnih Alpah, smo opisali dve novi asociaciji Crepido terglouensis-Potentilletum nitidae (zveza Thlaspion rotundifolii) in Saxifrago carniolicae-Cerastietum uniflorae (zveza Arabidion caeruleae).

Razširjenost lišajev iz skupine Lobaria s. lat. v Sloveniji / Distribution of lichens from the Lobaria s. lat. group in Slovenia
Authors: Mrak Tanja 
Published: September 2017

V Sloveniji iz skupine Lobaria s. lat. zasledimo najdbe petih vrst, in sicer Lobaria pulmonaria (L.) Hoffm. in Lobaria linita (Ach.) Rabenh., Lobarina scrobiculata (Scop.) Nyl. ter Ricasolia virens (With.) H.H. Blom. & Třnsberg in Ricasolia amplissima (Scop.) De Not. Epifitske vrste iz skupine Lobaria s. lat. se pojavljajo v združbi Lobarion, ki je zelo občutljiva na gozdarske posege in zračno onesnaženje. Za naštete vrste smo pregledali zgodovinske in sodobne vire, in izrisali njihove karte razširjenosti. Hkrati smo pregledali, na katerih substratih uspevajo ter v katerih habitatih oz. združbah. Preverili smo status teh vrst v bližnjih evropskih državah, kjer je lihenologija bolje razvita. Naštete vrste so v Sloveniji vezane na območja z veliko količino padavin, največ najdb je z območja alpsko-dinarske pregrade. Za vse vrste, razen za navadnega pljučarja (L. pulmonaria), smo uspeli najti zelo majhno število navedb. Status populacij vrst ni znan. Izpostavili smo možne dejavnike, ki ogrožajo obstoj vrst iz skupine Lobaria s. lat. v Sloveniji. Ključne besede: lihenizirane glive, epifitski lišaji, karte razširjenosti, Lobaria In Slovenia, findings of five species from the Lobaria s.lat. group of lichens are recorded, namely Lobaria pulmonaria (L.) Hoffm. and Lobaria linita (Ach.) Rabenh., Lobarina scrobiculata (Scop.) Nyl., Ricasolia virens (With.) H. H. Blom. & Tønsberg and Ricasolia amplissima (Scop.) De Not. Epiphytic species from the Lobaria s. lat. group occur in Lobarion community, which is very sensitive to forestry interventions and air pollution. For these species, the historical and contemporary sources were investigated and distribution maps produced. At the same time, it was examined which substrates, habitats and forest communities are preferred by the species. The status of these species in neighbouring lichenologically better developed European countries, was checked. Listed species are related to areas of high mean annual precipitation areas in Slovenia, most of the finds are from the area of the Alpine-Dinaric barrier. For all species except for L. pulmonaria, we managed to find a very small number of entries. The status of populations is unknown. The potential factors that threaten the existence of species from the group Lobaria s. lat. in Slovenia are highlighted.Keywords: lichenized fungi, epiphytic lichens, distribution maps, Lobaria
Cultivable bacterial microbiota from choanae of free-living birds captured in Slovenia / Kultivabilna bakterijska mikrobiota iz sapišč prosto¬živečih ptic, ujetih v Sloveniji

Published: September 2017

We have analysed the structure of cultivable choanal microbiota from free-living birds in relation to bird diet, its richness and the relative number of opportunistic bacteria acquired from the environment. For this purpose, we have taken choanal swabs from 25 free-living birds representing 13 different bird species captured in Slovenia. From the grown cultures, 98 bacterial colonies were isolated and their 16S rRNA genes sequenced. Most of the bacteria belonged to the phylum Actinobacteria (52 %), Proteobacteria (31 %), Firmicutes (15 %) and Bacteroidetes (4 %). Thirty-two percent of sampled birds were colonized by known human opportunists and 44 % of birds by at least one known plant pathogen. Hierarchical clustering of the analyzed microbiota grouped the birds according to their predominant diet. The richness of choanal microbiota from birds feeding mainly on insects was poorer compared to the birds feeding on diverse animal and plant material. The study has shown that the free-living birds carry an important reservoir of opportunistic human and plant pathogenic bacteria in their upper respiratory tract. To get a deeper insight into its composition, a bigger pool of birds will have to be analyzed in the future.Keywords: birds, microbiota, choanae, pathogenic bacteria, diet Sestavo kultivabilne bakterijske mikrobiote v sapiščih prostoživečih ptic smo analizirali z vidika vpliva prehrane, bogatosti mikrobiote in prisotnosti oportunističnih bakterij. Petindvajsetim prostoživečim pticam, ki so bile ujete v Sloveniji in so pripadale 13 vrstam, smo odvzeli bris sapišča. Po nacepitvi brisov na mikrobiološka gojišča in gojenju, smo izolirali 98 bakterijskih kolonij in jim določili nukleotidno zaporedje gena za 16S rRNK. Večina izoliranih bakterij je pripadala deblu Actinobacteria (52 %), Proteobacteria (31 %), Firmicutes (15 %) in Bacteroidetes (4 %). Pri približno eni tretjini ptic (32 %) smo iz sapišča izolirali vsaj eno oportunistično bakterijsko vrsto, ki lahko povzroča okužbe pri ljudeh. Pri slabi polovici ptic (44 %) pa smo v sapišču našli vsaj eno bakterijsko vrsto, ki lahko okuži rastline. Z metodo hierarhičnega združevanja smo pokazali, da imajo ptice s podobno prehrano, podobno bakterijsko mikrobioto sapišč. Ptice, ki se prehranjujejo pretežno z žuželkami so imele manj bogato mikrobioto kot ptice, ki se prehranjujejo z bolj raznoliko živalsko in rastlinsko hrano. Raziskava je tudi pokazala, da so zgornja dihala prostoživečih ptic pomemben rezervoar oportunističnih bakterij, ki lahko okužijo ljudi in rastline. Da bi dobili globji vpogled v sestavo mikrobiote zgornjih dihal, bi v prihodnosti morali povečati število analiziranih ptic.Ključne besede: ptice, mikrobiota, sapišče, patogene bakterije, prehrana
Silver fir (Abies alba Mill.) ectomycorrhiza across its areal – a review approach / Ektomikorizni simbionti bele jelke (Abies alba Mill.) na naravnem območju razširjenosti – pregled
Authors: Unuk Tina , Grebenc Tine 
Published: September 2017

Silver fir is a long-living ecologically valuable and indigenous conifer species. In temperate forests it is considered as a ˝stabilization tree species˝. Currently, knowledge of silver fir ectomycorrhiza community is manly based on morphological-anatomical description of ectomycorrhizal fungi and their fruiting bodies. Only recently few studies were published in which authors identified ectomycorrhizal symbionts of silver fir with an aid of molecular (DNA-based) markers. We analysed the silver fir ectomycorrhiza diversity and species richness from different geographic areas and stand types. From all together nine original studies we calculated average species richness as well as a Bray-Curtis similarity index. The highest species diversity was observed in studies where a combination of morphological-anatomical and molecular approaches were used for identification. Bray-Curtis similarity index indicated highest dissimilarity of the southern sites comparing to other areas. We correlated the observed outcome to differences in soil conditions, climate, and only basic identification approach.Keywords: Silver fir, ectomycorrhiza, literature review, community composition, site conditions, species diversity, species richness Bela jelka je vednozelena drevesna vrsta, ki ima v naravnih gozdovih ekološko pomembno vlogo, saj velja za stabilizacijsko drevesno vrsto. Podatki o ektomikoriznih simbiontih bele jelke pretežno temeljijo na morfološko-anatomskih opisih ektomikoriznih gliv in njihovih trosnjakov. Šele v zadnjih letih je bilo objavljenih nekaj študij, v katerih so avtorji združbo ektomikoriznih gliv bele jelke analizirali z molekularnimi pristopi. V preglednem članku smo analizirali rezultate pestrosti ektomikorize bele jelke z devet lokacij in preračunali povprečne vrednostmi vrstne pestrosti ter Bray-Curtisov indeks podobnosti združb. Največjo vrstno pestrost smo ugotovili za vzhodni del areala bele jelke. Poleg ugodnih rastiščnih razmer k temu predvidoma doprinesejo tudi kombinacija uporabljenih metod za identifikacijo. Bray-Curtisov indeks podobnosti združb kaže, da med zastopanimi regijami znotraj areala (centralna, vzhodna in južna) po vrstni sestavi najbolj odstopajo rastišča v južnem arealu bele jelke. Odstopanja vrstne sestave lahko povežemo z razlikami v pH tal, s tipom tal in s toplejšo, za belo jelko manj primerno klimo.Ključne besede: bela jelka, ekomikoriza, pregledni članek, združba ektomikorize na jelki, rastišči pogoji, bogastvo vrst, vrstna pestrost
How Quickly Do Fish Communities Recover From Boat Electrofishing in Large Lakes?
Authors: Smith Bradley J. , Simpkins Darin G. , Strakosh Timothy R. 
Published: September 2017

AbstractFor specific sampling questions researchers may need to target ideal habitats concurrently and collect reliable fish community data, but unfortunately, we know little about the recovery rate of fish communities in areas recently subjected to electrofishing. In small systems, electrofishing can quickly deplete a sample area but this effect is unlikely at larger spatial scales. We conducted an experiment to identify how quickly fish communities recover from electrofishing in Green Bay, an embayment of Lake Michigan. We conducted electrofishing at 31 sites that were randomly assigned to be resampled at 0.25, 1, 3, 6, 24, or 48 h postrelease of marked fish. We marked all fish ≥ 150 mm and released them at their capture site. We found no differences in catch per unit effort, mean total length, species richness, Shannon's diversity, or Shannon's evenness between marking and recapture runs for any length of recovery duration between electrofishing runs. We recaptured only one of 349 marked fish in the site where it was released. Recapture of five fish in areas outside where they were released was unrelated to recovery duration between electrofishing events. In large, open systems like Green Bay, we found that disturbances caused by electrofishing are temporary (&lt; 15 min) and suspect that any fish removed are quickly replaced by new immigrants to the study area. Due to high turbidity in this eutrophic–hypereutrophic system, we suspect that electrofishing efficiency was low; therefore resampling had the potential benefit of collecting individuals missed during marking runs. We conclude that fish communities in large lakes recover quickly following electrofishing and sites can be sampled concurrently within the same day and provide similar, or additional, fish community information.
Acute ischemic pancreatitis: A rare complication of empirical gastroduodenal artery embolization
Authors: Chua Wei Ming , Venkatanarasimha Nanda , Damodharan Karthikeyan 
Published: September 2017

AbstractEmpirical embolization of the gastroduodenal artery (GDA) is accepted as a safe and effective treatment option for endoscopy-refractory nonvariceal upper gastrointestinal bleeding (UGIB) in patients with high surgical risk. Nontarget embolization is a recognized complication of transarterial embolization, however, symptomatic pancreatic injury is extremely rare. We report a patient who developed acute ischemic pancreatitis immediately after embolization of the GDA, which was confirmed intraoperatively. Interventionists as well as referring clinicians need to be aware of this rare but life threatening complication.

Published: September 2017

Abstract
Purpose: To evaluate utility, pattern, and extent of perfusion abnormalities in traumatic brain injury by using whole-brain computed tomography perfusion (CTP) and to assess co-relation of CTP data clinically with Glasgow outcome score (GOS). Materials and Methods: Prospective analytic evaluation of the traumatic head injury patients who were immediately taken up for CTP was done. Patient's demographic, clinical, and radiological findings were tabulated and analyzed. GOS was measured by a neurosurgeon after 3 months of trauma who was blinded to CTP results. Results: Of the 78 patients included in this study, 28 patients were found to have GOS 5, 19 of them had GOS 4, 27 of them had GOS 3, and 4 of them had a GOS 2. Higher mean cerebral blood flow (CBF) and cerebral blood volume (CBV) values were observed in those who had a better GOS, i.e., 4 or 5, whereas those in the GOS range ≤3 had lower mean CBF and CBV values. Conclusion: Statistically significant positive correlation was found between cerebral perfusion parameters with that of GOS. CBF of frontal area shows better correlation with GOS. CBF was the most important predictor among all the perfusion parameters.
Radiological requirements for surgical planning in cochlear implant candidates
Authors: Alam-Eldeen Mohamad Hasan , Rashad Usama Mohamed , Ali Al Hussein Awad 
Published: September 2017

Abstract
Objective: This study is concerned with clarification of radiological findings that should be addressed and reported in patients listed for cochlear implant (CI) operation. These findings may force a surgeon to consider modifications of the surgical approach by a CI surgeon. Materials and Methods: The study was performed from January 2015 to January 2016. It included 50 patients with severe-to-profound sensorineural hearing loss who fulfilled the criteria for CI. Patients underwent CI surgery in the Department of Otolaryngology. All patients underwent preoperative computed tomography (CT) and magnetic resonance imaging (MRI) assessment in the Department of Diagnostic Radiology. Combined examination of the CT and MRI by the radiologist and the surgeon was advocated. Results: Many anatomical variants were observed regarding the pattern of mastoid pneumatization, position of middle cranial fossa dura, sigmoid sinus position jugular bulb position, and the size and position of the mastoid segment of facial nerve canal. Labyrinthitis ossificans was seen in 3 patients (6%), otospongiosis in 1 patient (2%), and dilated vestibular aqueduct and endolymphatic sac in 9 patients (18%). Conclusion: Cochlear implantation is a major treatment modality in patients with severe-to-profound sensorineural hearing loss. Radiological evaluation is integral in surgery planning.
Long Sets of Lengths With Maximal Elasticity

Published: September 2017

AbstractWe introduce a newinvariant describing the structure of sets of lengths in atomicmonoids and domains. For an atomic monoid H, let Δρ(H) be the set of all positive integers d that occur as differences of arbitrarily long arithmetical progressions contained in sets of lengths havingmaximal elasticity ρ(H). We study Δρ(H) for transfer Krull monoids of finite type (including commutative Krull domains with finite class group) with methods from additive combinatorics, and also for a class of weakly Krull domains (including orders in algebraic number fields) for which we use ideal theoretic methods.

“Onde é o meu lar?” A aplicação da convenção da Haia sobre os aspectos civis do sequestro internacional de crianças e o princípio do melhor interesse da criança
Authors: Andrade Ribeiro Mayra Thais 
Published: September 2017

O artigo analisa a aplicação da Convenção da Haia sobre os Aspectos Civis do Sequestro Internacional de Crianças (1980) a partir do principio do melhor interesse da criança. O termo “sequestro” é referente ao ato do deslocamento ilegal, do infante de seu país ou a sua retenção indevida em outro que não o de sua residência habitual, sem a autorização da outra pessoa detentora da guarda, ainda que compartilhada. A metodologia utilizada nesta pesquisa pauta-se no procedimento jurídico-analítico, através do levantamento bibliográfico especializado, verificação de documentos e dados oficiais publicados e jurisprudência. Conclui-se que, enquanto o principio do melhor interesse da criança não for o ponto principal de interpretação e aplicação da Convenção, os trabalhos realizados pelas autoridades competentes serão ineficientes nas questões envolvendo o pedido de retorno ou direito de visita.
