PENGARUH PEMBERIAN BERBAGAI POLLARD TEROLAH TERHADAP PERTUMBUHAN ORGAN PENCERNAAN AYAM BROILER UMUR 7 MINGGU
Authors: Utama Cahya Setya , Sulistiyanto Bambang , Wicaksono T. A.
Published: October 2019

The study aimed to examine the effect of using pollard in rations on the growth of proventricular, ventricular, duodenal, jejunal and ileal organs in 7-week-old broiler chickens. The research material used 200 broiler chickens aged 7 weeks with an average weight of 859 ± 59 g with each experimental unit consisting of 8 - 9 tails. The design used was a completely randomized design with 5 treatments and 3 replications. Treatment is given (T0 = Comersial feeds, T1 = Feed with pollard without processing, T2 = Feed with pollard treated physically, T3 = Feed with pollard treated physically and biologically, and T4 = Feed with pollard treated physically and biology 60%) and 3 replications. Based on the results of the study it can be concluded that the administration of pollard treated physically and biologically has not been able to increase all the relative weights of the digestive organs of broiler chickens aged 7 weeks. In the proventriculus organ, the treatment can increase the relative weight of broiler digestive organs, but the relative weight of the proventriculus produced is still relatively normal. Measurement of broiler chicken organ weight needs to be done per week to determine the rate of increase in the relative weight of the optimal digestive organs, so that the maximum data on the growth of broiler organs are obtained optimally

IDENTIFIKASI KERJASAMA PENGENDALIAN PEMANFAATAN RUANG DENGAN POLA PARTISIPATIF DI KOTA PAMANUKAN
Authors: Jaya Purnama
Published: October 2019

Setiap kegiatan perlu mendapat perhatian dalam konteks penataan ruang. RTRW 2006-2026 Subang belum menjadi kebijakan publik karena belum terbuka untuk diketahui oleh seluruh unsur masyarakat. Studi ini bertujuan agar pembangunan sesuai dengan rencana tata ruang, dan dapat membantu pemerintah dalam mengidentifikasi pengendalian dan pemanfaatan ruang. Hasil studi ini mengidentifikasi perlunya pengendalian pemanfaatan ruang melalui instrumen perijinan dan arahan pedoman pengendalian penataan tata ruang. Disarankan bahwa perlu adanya instansi yang memberikan rekomendasi, sistem perijinan,  rumusan keterpaduan, dan ijin pemanfaatan ruang. Pada kasus ini menunjukkan bahwa di Kabupaten Subang belum ada fungsi mediasi, advokasi dan evaluasi yang baik, sehingga persoalan tersebut timbul. Berbagai institusi yang ada nampaknya kurang efektif dalam menanggapinya, selain pihak DPRD-nya. Disarankan, materi hasil studi ini agar ditindaklanjuti dengan penyusunan Peraturan Daerah tentang “Pengendalian Pemanfaatan Ruang Kabupaten Subang”.

Abstract - The selection process is a series of activity steps used to decide whether prospective recipients of subsidies are accepted or not. The purpose of the decision support system for selection of recipients of prosperous rice subsidies (RASTRA) is to assist the Community Empowerment Section in conducting a quick and precise selection process that is in accordance with several criteria, namely, the amount of income, type of work, number of dependents, age and home ownership. Therefore, researchers use the Analyticalcal Hierarchy Process (AHP) method to solve existing problems. This method was chosen because of a form of decision support model in which the main equipment is a functional hierarchy with the main input of human perception, ie in this case an expert in the problem of the selection process for the selection of prospective recipients of prosperous rice subsidies. The results of this study are in the form of the application of a selection decision support system that was built as a tool for determining whether citizens are entitled to subsidies.

Microbubbles decorated with dendronized magnetic nanoparticles for biomedical imaging: effective stabilization via fluorous interactions

Published: October 2019

Dendrons fitted with three oligo(ethylene glycol) (OEG) chains, one of which contains a fluorinated or hydrogenated end group and bears a bisphosphonate polar head (CnX2n+1OEG8Den, X = F or H; n = 2 or 4), were synthesized and grafted on the surface of iron oxide nanoparticles (IONPs) for microbubble-mediated imaging and therapeutic purposes. The size and stability of the dendronized IONPs (IONP@CnX2n+1OEG8Den) in aqueous dispersions were monitored by dynamic light scattering. The investigation of the spontaneous adsorption of IONP@CnX2n+1OEG8Den at the interface between air or air saturated with perfluorohexane and an aqueous phase establishes that exposure to the fluorocarbon gas markedly increases the rate of adsorption of the dendronized IONPs to the gas/water interface and decreases the equilibrium interfacial tension. This suggests that fluorous interactions are at play between the supernatant fluorocarbon gas and the fluorinated end groups of the dendrons. Furthermore, small perfluorohexane-stabilized microbubbles (MBs) with a dipalmitoylphosphatidylcholine (DPPC) shell that incorporates IONP@CnX2n+1OEG8Den (DPPC/Fe molar ratio 28:1) were prepared and subsequently characterized using both optical microscopy and an acoustical method of size determination. The dendrons fitted with fluorinated end groups lead to smaller and more stable MBs than those fitted with hydrogenated groups. The most effective result is already obtained with C2F5, for which MBs of ≈1.0 μm in radius reach a half-life of ≈6.0 h. An atomic force microscopy investigation of spin-coated mixed films of DPPC/IONP@C2X5OEG8Den combinations (molar ratio 28:1) shows that the IONPs grafted with the fluorinated dendrons are located within the phospholipid film, while those grafted with the hydrocarbon dendrons are located at the surface of the phospholipid film.
Synthetic terpenoids in the world of fragrances: Iso E Super®is the showcase
Authors: Stepanyuk Alexey , Kirschning Andreas
Published: October 2019

The history of fragrances is closely associated with the chemistry of terpenes and terpenoids. For thousands of years mankind mainly used plant extracts to collect ingredients for the creation of perfumes. Many of these extracts contain complex mixtures of terpenes, that show distinct olfactoric properties as pure compounds. When organic synthesis appeared on the scene, the portfolio of new scents increased either in order to substitute natural fragrances without change of olfactoric properties or to broaden the scope of scents. This short review describes the story of the most successful synthetic fragrance ever which is called Iso E Super®as it is an ingredient in a large number of perfumes with varying percentages and is the first example being used as a pure fragrance. Structurally, it is related to natural terpenes like many other synthetic fragrances. And indeed, the story began with a classic in the field of fragrances, the natural product ionone.
Model of the Search for Extraterrestrial Intelligence with Coronagraphic Imaging

Published: October 2019

We present modeled detection limits of the Gemini Planet Imager (GPI) and the Wide-Field Infrared Space Telescope (WFIRST) to an optical and infrared laser which could be used by an extraterrestrial civilization to signal their presence. GPI and WFIRST could utilize a coronagraph to search for extraterrestrial intelligence in the present and future. We use archival data for GPI stars and simulated WFIRST observations to find the detectable flux ratio of a laser signal to residual scattered starlight around the target star. This flux ratio is then converted to detectable power as a function of distance from the parent star. For GPI, we assume a monochromatic laser wavelength of 1.55 μm and a wavelength of 575 nm for WFIRST. We assume that the lasers are projected through a 10 m aperture, and that the intensity of the laser beam follows a Gaussian profile. Our analysis is performed on six stars with spectral types later than F within 20 pc (with an emphasis on solar analogs at different distances). The most notable result is the detection limit for τ Ceti, a G5V star with four known exoplanets, two of those within the habitable zone (HZ). The result shows that a 24 kW laser is detectable from τ Ceti from outside of the HZ with GPI and a 7.3 W laser is detectable from within τ Ceti’s HZ by WFIRST.
First Detection of CS Masers around a High-mass Young Stellar Object, W51 e2e
Authors: Ginsburg Adam , Goddi Ciriaco
Published: October 2019

We report the discovery of maser emission in the two lowest rotational transitions of CS toward the high-mass protostar W51 e2e with the Atacama Large Millimeter/submillimeter Array and the Jansky Very Large Array. The masers from CS J = 1−0 and J = 2−1 are neither spatially nor spectrally coincident (they are separated by ∼150 au and ∼30

), but both appear to come from the base of the blueshifted outflow from this source. These CS masers join a growing list of rarely detected maser transitions that may trace a unique phase in the formation of high-mass protostars.
A Pulsar Wind Nebula Embedded in the Kilonova AT 2017gfo Associated with GW170817/GRB 170817A

Published: October 2019

The first detected gravitational wave GW170817 from a binary neutron star merger is associated with an important optical transient AT 2017gfo, which is a direct observation of kilonova. Recent observations suggest that the remnant compact object of the binary neutron star merger associated with GW170817/GRB 170817A may be a stable long-lived magnetized neutron star. In this situation, there would be a pulsar wind nebula (PWN) embedded inside the dynamic ejecta. The PWN emission may be absorbed by the ejecta or leak out of the system. We study the effect of the PWN emission on the observed light curves and radiation spectra. Different from previous works, the absorption and leakage of the PWN emission are all involved in our model, where the absorption of the PWN emission heats up the ejecta and alters its radiation. It is found that the characteristic emission of the embedded PWN quickly evolves. For the multiband and long-term observations of AT 2017gfo, we find that the dynamic ejecta with a PWN emission can fit the observational data very well, especially for the light curves at t ∼ 5 days and those in the late phase. In addition, our model can naturally generate the thermal to nonthermal spectrum evolution of AT 2017gfo. Our fitting result suggests that a PWN is embedded in the AT 2017gfo.
Column Density, Kinematics, and Thermal State of Metal-bearing Gas within the Virial Radius of z ∼ 2 Star-forming Galaxies in the Keck Baryonic Structure Survey

Published: October 2019

We present results from the Keck Baryonic Structure Survey (KBSS) including the first detailed measurements of the column densities, kinematics, and internal energy of metal-bearing gas within the virial radius (35–100 physical kpc) of eight ∼L* galaxies at z ∼ 2. From our full sample of 130 metal-bearing absorbers, we infer that halo gas is kinematically complex when viewed in singly, doubly, and triply ionized species. Broad O vi and C iv absorbers are detected at velocities similar to the lower-ionization gas but with a very different kinematic structure, indicating that the circumgalactic medium (CGM) is multiphase. There is a high covering fraction of metal-bearing gas within 100 kpc, including highly ionized gas such as O vi; however, observations of a single galaxy probed by a lensed background QSO suggest the size of metal-bearing clouds is small (<400 pc for all but the O vi-bearing gas). The mass in metals found within the halo is substantial, equivalent to ≳25% of the metal mass within the interstellar medium. The gas kinematics unambiguously show that 70% of galaxies with detected metal absorption have some unbound metal-enriched gas, suggesting galactic winds may commonly eject gas from halos at z ∼ 2. When modeled assuming that ions with different ionization potentials can originate within a single gaseous structure, significant thermal broadening is detected in CGM absorbers that dominates the internal energy of the gas. Some 40% of the detected gas has temperatures in the range 104.5–5.5 K where cooling times are short, suggesting the CGM is dynamic, with constant heating or cooling to produce this short-lived thermal phase.
Broadband X-Ray Constraints on the Accreting Black Hole in Quasar 4C 74.26
Authors: Tzanavaris P. , Yaqoob T. , LaMassa S. , Yukita M. , Ptak A.
Published: October 2019

X-ray data for quasar 4C 74.26 have previously been modeled with a broad Fe Kα emission line and reflection continuum originating in the inner part of the accretion disk around the central supermassive black hole (SMBH), i.e., the strong-gravity regime. We modeled broadband X-ray spectra from Suzaku and NuSTAR with mytorus, self-consistently accounting for Fe Kα line emission, as well as direct and reflected continuum emission, from matter with a finite column density. A narrow Fe Kα emission line originating in an X-ray reprocessor with solar Fe abundance far from the central SMBH is sufficient to produce excellent fits for all spectra. For the first time, we are able to measure the global column density, out of the line of sight, to be in the range ∼1.5 to ∼

, i.e., in the Compton-thick regime, while the line-of-sight column density is Compton-thin in all observations. The Fe Kα emission line is unresolved in all observations but one. The Compton-scattered continuum from distant matter removes the need for relativistic broadening of the Fe Kα emission line, which is required for SMBH spin measurements. The resolved line observation can alternatively be modeled with a relativistic model but we do not find evidence for a truncated accretion disk model. We conclude that the X-ray emission in these 4C 74.26 data is unlikely to originate in the inner accretion disk region and thus cannot be used to measure SMBH spin.

We present new, deep observations of the Phoenix cluster from Chandra, the Hubble Space Telescope, and the Karl Jansky Very Large Array. These data provide an order-of-magnitude improvement in depth and/or angular resolution over previous observations at X-ray, optical, and radio wavelengths. We find that the one-dimensional temperature and entropy profiles are consistent with expectations for pure-cooling models. In particular, the entropy profile is well fit by a single power law at all radii, with no evidence for excess entropy in the core. In the inner ∼10 kpc, the cooling time is shorter than any other known cluster by an order of magnitude, while the ratio of the cooling time to freefall time (t
cool/t
ff) approaches unity, signaling that the intracluster medium is unable to resist multiphase condensation on kpc scales. The bulk of the cooling in the inner ∼20 kpc is confined to a low-entropy filament extending northward from the central galaxy, with t
cool/t
ff ∼ 1 over the length of the filament. In this filament, we find evidence for ∼1010
M
⊙ in cool (∼104 K) gas (as traced by the [O ii]λλ3726,3729 doublet), which is coincident with the low-entropy filament and absorbing soft X-rays. The bulk of this cool gas is draped around and behind a pair of X-ray cavities, presumably bubbles that have been inflated by radio jets. These data support a picture in which active galactic nucleus feedback is promoting the formation of a multiphase medium via uplift of low-entropy gas, either via ordered or chaotic (turbulent) motions.
Particle Acceleration at the Pileup Collision of the Twin Shock

Published: October 2019

Ground-level enhancement (GLE) events are often associated with large gradual solar events such as fast coronal mass ejections (CMEs), but not all fast CMEs lead to GLE events. Is there a type of coordinated CME that could produce GLEs with larger intensity and higher energies than those in the normal fast isolated CMEs? Here we propose a twin-shock scenario driven by the twin CME coordinately, in which the posterior shock catches up with the preceding shock and has a pileup collision. In the present study, we chose the first GLE event of the solar cycle 24 occurring on 2012 May 17 as an example to investigate the probable association with the twin-shock scenario. We use a dynamic Monte Carlo method to examine the energy spectrum with relevance to the GLE event. In the twin-shock scenario, the seed energetic particles produced by the normal preceding shock can be injected into the posterior shock for reacceleration efficiently. As a result, we obtain the detailed energy spectrum of the solar energetic particles (SEPs) with different behaviors at the related episodes of the twin-shock evolution. Therefore, we predict that the pileup collision of the twin shock would dominate a concave energy spectral slope in the 2012 May 17 SEP event.
The Cosmic Distance Duality Relation with Strong Lensing and Gravitational Waves: An Opacity-free Test
Authors: Liao Kai
Published: October 2019

The cosmic distance duality relation (CDDR) is a fundamental rule in cosmological studies. Given the redshift z, it relates luminosity distance D

L
with angular diameter distance D

A
through

. Many efforts have been made to test CDDR with various observational approaches. However, to the best of our knowledge, those methods are always affected by cosmic opacity, which could violate CDDR owing to the non-conservation of photon number. Such a mechanism is more related to astroparticle physics. In this work, in order to directly study the nature of spacetime, i.e., to disentangle it from astroparticle physics, we propose a new strategy to test CDDR, with strong lensing providing D

A
and gravitational waves (GWs) providing D

L
. It is known that the propagation of GWs is unaffected by cosmic opacity. We demonstrate that distances from observations of optical lensing are also opacity-free. These two kinds of distance measurements make it possible to test spacetime. Our results show that the constraints on the deviations of CDDR will be very competitive with current techniques.

We report on the discovery of eight repeating fast radio burst (FRB) sources found using the Canadian Hydrogen Intensity Mapping Experiment (CHIME) telescope. These sources span a dispersion measure (DM) range of 103.5–1281 pc cm−3. They display varying degrees of activity: six sources were detected twice, another three times, and one 10 times. These eight repeating FRBs likely represent the bright and/or high-rate end of a distribution of infrequently repeating sources. For all sources, we determine sky coordinates with uncertainties of ∼10′. FRB 180916.J0158+65 has a burst-averaged DM = 349.2 ± 0.3 pc cm−3 and a low DM excess over the modeled Galactic maximum (as low as ∼20 pc cm−3); this source also has a Faraday rotation measure (RM) of −114.6 ± 0.6 rad m−2, which is much lower than the RM measured for FRB 121102. FRB 181030.J1054+73 has the lowest DM for a repeater, 103.5 ± 0.3 pc cm−3, with a DM excess of ∼70 pc cm−3. Both sources are interesting targets for multi-wavelength follow-up due to their apparent proximity. The DM distribution of our repeater sample is statistically indistinguishable from that of the first 12 CHIME/FRB sources that have not yet repeated. We find, with 4σ significance, that repeater bursts are generally wider than those of CHIME/FRB bursts that have not repeated, suggesting different emission mechanisms. Many of our repeater events show complex morphologies that are reminiscent of the first two discovered repeating FRBs. The repetitive behavior of these sources will enable interferometric localizations and subsequent host galaxy identifications.

A collection of fungi was isolated from macroalgae of the generaGracilaria,EnteromorphaandUlvain the estuary Ria de Aveiro in Portugal. These isolates were characterized through a multilocus phylogeny based on ITS region of the ribosomal DNA, beta-tubulin (tub2) and translation elongation factor 1 alpha (tef1-α) sequences, in conjunction with morphological and physiological data. These analyses showed that the isolates represented an unknown fungus for which a new genus,Neptunomycesgen. nov.and a new species,Neptunomyces aureussp. nov.are proposed. Phylogenetic analyses supported the affiliation of this new taxon to the family Didymosphaeriaceae.
Molecular sexing and intersexual differences in the morphometry of the Hangnest Tody-Tyrant Hemitriccus nidipendulus (Passeriformes: Rhynchocyclidae)

Published: October 2019

Variation in the morphometry of individuals in a population may result from natural or sexual selection. In the present study we investigated morphometric differences between males and females of a bird species endemic to the Brazilian Atlantic Forest, the Hangnest Tody-Tyrant,Hemitriccus nidipendulus(Wied, 1831), with no apparent sexual dimorphism. All individuals (n = 56) were sexed by PCR amplification of the intronic fragments of theCHDZ/CHDWalleles obtained from blood samples, and 12 morphometric measurements were recorded. The molecular configuration was similar to that described for other species of Passeriformes, with males presenting a single band of approximately 360 base pairs (bp), and females with two bands of 360 and 400 bp. Males had significantly larger tarsi and wings than the females, while the females had two larger beak measurements. This indicates that differential selection pressures may be modeling the morphometry of the Hangnest Tody-Tyrant. In the males, larger tarsi and wings may be beneficial for the exploration of the habitat or the acquisition of potential mates, while females with larger beaks may be able to exploit larger food items and forage more efficiently. However, these hypotheses need to be tested empirically in future studies.
Malaise dans le quartier. De quoi le sentiment d’insécurité est-il le symptôme ?
Authors: Vallet Pascal
Published: October 2019

L’article traite de l’interprétation de situations quotidiennes du point de vue peu étudié d’habitants qui éprouvent un sentiment d’insécurité. En s’appuyant sur les résultats d’une enquête réalisée à Montreynaud, un quartier de Saint-Étienne classé en zone de sécurité prioritaire, il présente trois profils d’habitants anxieux (c’est-à-dire éprouvant une anxiété sécuritaire) : celui des propriétaires qui se sentent « piégés », celui des locataires exaspérés par les incivilités, et celui des femmes inquiètes pour leurs enfants. Ces inquiétudes correspondent à trois expressions d’un malaise plus général, et l’article montre aussi que ce malaise, qui s’objective dans des ressentiments, dans l’ethnicisation des rapports entre groupes sociaux ou dans des inquiétudes quant à l’avenir familial, est aussi traversé par le sentiment d’abandon.
Screen Time: The Impact of Digital Technology on Children and Strategies in Care

Published: October 2019

Media and digital devices are an integral part of the world today. Despite potential benefits of media time, excessive or inappropriate use of technology is having a significant impact on the development and health of children. There is a relationship between increased screen time and greater risk of physical health complications, mental health concerns, and negative outcomes on cognitive, language, social, and emotional development. Successful evidence-based interventions and screening initiatives are available for reducing unhealthy media use in children. Providers need to be aware of media-use guidelines, screen for at-risk media use, and provide parental education as well as recommend interventions when indicated. [

Erosive Retinopathy and Retinal Detachment From Depot Intravitreal Triamcinolone Acetonide Injection at the End of Pars Plana Vitrectomy
Authors: Sisk Robert A. , Patel Yogin P. , Foster Robert E. , Petersen Michael R.
Published: October 2019

BACKGROUND AND OBJECTIVE:

Intravitreal triamcinolone acetonide (IVTA) used as a surgical adjuvant for pars plana vitrectomy (PPV) can stain cortical vitreous, control postoperative inflammation, and reduce retinal edema. Sterile endophthalmitis uncommonly complicates office-based IVTA injection. The authors report a new complication of IVTA depot injection at the end of PPV.

PATIENTS AND METHODS:

Retrospective records review of all patients treated at the Cincinnati Eye Institute with PPV between January 1, 2011, and December 31, 2017, who developed a triad of sterile endophthalmitis, atrophic retinal breaks under the depot IVTA in the inferior retina, and rhegmatogenous retinal detachment (RRD). Eyes with flap tears, solely superior breaks, or stretch holes from proliferative vitreoretinopathy causing RRD were excluded.

RESULTS:

Eight eyes of eight patients (four males and four females; mean age: 73.7 years) who received 4 mg or 8 mg IVTA depot at the end of PPV surgery presented at a mean of 23.5 days following PPV with RRD (one macula-involving, seven macula-sparing), requiring treatment with PPV in six eyes and laser retinopexy alone in two eyes. Seven eyes that underwent membrane peeling (MP) received IVT to prevent cystoid macular edema (CME) and one eye with prior MP was treated for CME. Mean vitreous inflammation was 2+ cell at 1 week postoperatively. Two patients had documented sterile endophthalmitis within the first week requiring vitreous cultures and antibiotics injections. Visual acuity (VA) for eyes requiring PPV for RD repair declined from 20/90 preoperatively to 20/212 at 6 months postoperatively. VA for eyes amenable to laser alone improved from 20/53 to 20/35. All eyes remained attached, with the exception of one patient who refused further treatment after developing recurrent detachment from PVR.

CONCLUSIONS:

Particle-induced sterile endophthalmitis from IVTA depot at the end of PPV surgery resulted in atrophic inferior retinal breaks and RRD as a newly described entity coined “erosive retinopathy.” All retinal detachment surgeries required silicone oil tamponade. Poor visual outcome at 6 months was common for eyes requiring PPV for RD repair. The authors recommend avoiding IVTA depot injection at the end of PPV.

Macular Choroidal Thickness Changes in Development, Progression, and Spontaneous Resolution of Epiretinal Membrane
Authors: Choi Eun Young , Han Jongwook , Lee Sung Chul , Lee Christopher Seungkyu
Published: October 2019

BACKGROUND AND OBJECTIVE:

To evaluate the association between macular choroidal thickness and the development, progression, and resolution of epiretinal membrane (ERM).

PATIENTS AND METHODS:

The patients (n = 38) with unilateral ERM eyes with definitive changes on optical coherence tomography (OCT) and healthy fellow eyes were observed retrospectively. ERM eyes were divided into three groups: Development/new-onset group (n = 14), progression group (n = 13), and resolution group (n = 11). In each group, the average changes of macular choroidal thickness over time in ERM eyes were compared with those in the fellow eyes

RESULTS:

Choroidal thickness significantly decreased from 174.0 μm at baseline to 132.3 μm at event time (
P
= .001) in the development group, and from 140.0 μm ± 30.0 μm to 120.5 μm (
P
= .002) in the progression group. Conversely, a significant increase in choroidal thickness was observed in the resolution group (from 205.2 μm to 222.6 μm;
P
= .004). The fellow eyes showed no significant changes in choroidal thickness in all three groups.

CONCLUSION:

Choroidal thinning in newly developed or significantly progressed ERM eyes and choroidal thickening in spontaneously resolved ERM eyes suggest a clinical implication of choroidal changes in ERM.

Protecting Vision in Patients With Diabetes With Ultra-Widefield Imaging: A Review of Current Literature
Authors: Singh Rishi P. , Hsueh Jessica , Han Michael M. , Kuriyan Ajay E. , Conti Felipe F. , Steinle Nathan , Weng Christina Y. , Wong Robert W. , Martinez Jose A. , Wykoff Charles C.
Published: October 2019

Ultra-widefield fundus imaging (UWFI) is a relatively new technology capable of capturing 200° images of the retina. Since vision changes can be irreversible in diabetic retinopathy (DR), recognition of prognostic biomarkers in the peripheral retina may prove invaluable toward optimizing the management and reducing the societal burden of this blinding disease. Following a bibliographic review using Pubmed, OVID Medline, Embase, and the Cochrane Library, the current review systematically examined 13 studies that compared UWFI to conventional screening techniques such as seven standard field (7SF) Early Treatment In Diabetic Retinopathy Study (ETDRS) and non-mydriatic multifield fundus photography (NMFP), as well as their scientific level of evidence. Overall, UWFI had good agreement with 7SF ETDRS and NMFP, and moderate agreement with dilated fundus examination. Seven additional studies were examined that considered the significance of peripheral lesions found on UWFI. These studies demonstrated that UWFI captured additional DR pathology in the peripheral retina that may not be evident if evaluation is limited to the posterior pole and may be relevant to patient outcomes. Future directions include but are not limited to the potential of UWFI to track the progression of DR with treatment.

Neuroimaging findings in Emanuel Syndrome
Authors: Xie Charlies L , Cardenas Agustin M
Published: October 2019

Emanuel syndrome is a rare inherited chromosomal abnormality caused by an unbalanced translocation of chromosomes 11 and 22. Clinically, Emanuel syndrome is characterized by a wide spectrum of congenital anomalies, dysmorphisms, and developmental disability often confused with other similar syndromes. Outside of genetic testing, diagnosis remains challenging and current literature on typical radiologic findings is limited. We present classic neuroimaging findings of Emanuel syndrome consistent with prior literature including microcephaly, microretrognathia, external auditory canal stenosis, and cleft palate; and also introduce the additional maxillofacial anomaly of dysplastic middle ear ossicles, to our knowledge not previously described in the literature. Recognition of findings leading to earlier diagnosis of Emanuel syndrome may improve outcomes and quality of life for patients and their families.
Remences senyors de remences: la família Tria d’Arenys
Authors: Feliu Gaspar
Published: October 2019

[ca] La finalitat d’aquest article és estudiar l’evolució de la família Tria d’Arenys durant els tres darrers segles de l’Edat Mitjana. La característica principal d’aquesta família és que era una família de remences que a la vegada eren batlles jurisdiccionals i senyors de remences. L’existència de remences senyors de remences és coneguda des de ja fa alguns anys, però ha tingut una difusió escassa. L’article permet estudiar per primer cop l’evolució a llarg termini d’una família de pagesos benestants i la seva actuació com a remences, senyors de remences i batlles. La conclusió principal és que la remença no era una servitud clàssica, sinó una categoria jurídica: comportava càrregues servils i econòmiques, però no implicava cap tipus de segregació ni impedia l’enriquiment ni l’ascens social.
El uso de horas de reloj en las ciudades de Castilla. Los ejemplos de Palencia y Valladolid
Authors: Pérez Álvarez Víctor
Published: October 2019

Las antiguas horas solares variaban de duración a lo largo del año y su recuento se iniciaba al amanecer y al anochecer. La llegada del reloj público a las ciudades y villas castellanas entre los siglos XIV y XV conlleva la introducción de las horas modernas o de reloj, que son de igual duración independientemente de la época del año y su recuento normalmente se comienza una sola vez al día. En este trabajo vamos a estudiar cómo se introducen estas nuevas horas de reloj en Castilla a través de los ejemplos de las ciudades de Palencia y Valladolid. Para ello explicaremos cómo conviven con las viejas horas solares y para qué actividades se emplean.
Iglesia, imperio y poder en el primer tercio del siglo XIV. El enfrentamiento entre el papado, Luis IV de Baviera y los Visconti de Milán desde la iglesia de Santiago de Compostela
Authors: Sánchez Sánchez Xosé M.
Published: October 2019

El pulso entre Papado e Imperio ha sido una constante en el contexto de la teoría política de la Edad Media. La oposición entre ambos tuvo en los años 20 del siglo XIV un nuevo episodio en el panorama europeo: el enfrentamiento material, doctrinal y político entre Juan XXII y Luis de Baviera, con los Visconti de Milán como peones destacados, y al hilo del cual se empezarán a delimitar las posiciones en la pre-configuración de los Estados Modernos. Este artículo analiza las cuatro comunicaciones relativas a la cuestión que el papa Juan XXII dirige entre 1324 y 1330 al arzobispo de Santiago de Compostela, Berenguel de Landoira, bien próximo al pontífice. Tales fuentes, no localizadas por lo de ahora en otras sedes y de las cuales editamos un documento, permiten desarrollar la incidencia del cambio en la teoría política en el noroeste peninsular así como el seguimiento de la cuestión.
Musique et cinématurgie chez Marcel Pagnol
Authors: Rossi Jérôme , Pfeffer Sylvain
Published: October 2019

L’étude se propose d’étudier l’utilisation de la musique dans les films réalisés par Marcel Pagnol, afin de préciser le rapport du metteur en scène à cette dernière. Obsédé par le rendu sonore de ses films, Pagnol va accorder une place de plus en plus importante à la musique et finir par l’intégrer pleinement au sein de sa « cinématurgie ». Ce faisant, il s’émancipe peu à peu des deux modèles de fonctionnement dont il dispose à ses débuts : la musique de scène et l’accompagnement musical de films muets. Cette évolution se fait progressivement, et grâce aux personnalités des différents compositeurs que le réalisateur engage sur ses longs-métrages. De l’ami Scotto au symphoniste Arthur Honegger, en passant par Henri Tomasi et Raymond Legrand, Pagnol prend conscience du pouvoir de la musique et contribue à l’émergence d’un art spécifiquement cinématographique.
Aux origines de la Cinémathèque québécoise
Authors: Godin-Hébert Antoine
Published: October 2019

En 1963, deux groupes de cinéphiles montréalais veulent fonder une cinémathèque en même temps. Le conflit entre Henri Langlois et la FIAF ne facilite pas l’harmonie entre les deux fondateurs Serge Losique et Guy L. Coté. Le premier se montre entièrement fidèle à la Cinémathèque française alors que le second demeure écartelé entre Langlois et la FIAF. En plus de ces embûches diplomatiques internationales, déterminantes au plan de l’approvisionnement en films, le contexte politique du Québec facilite et complique à la fois les choses. D’une part, le gouvernement québécois investit davantage dans la culture, de l’autre, les francophones s’affirment face aux anglophones en prenant leur place dans les institutions existantes ou en en créant de nouvelles. Le groupe de Coté, Connaissance du Cinéma, doit donc négocier son indépendance vis-à-vis du Canadian Film Institute, lui-même déjà membre provisoire de la FIAF. Sous forme d’enquête historique, cet article nous plonge dans les archives de la Cinémathèque québécoise pour mieux comprendre les premières années mouvementées et incertaines de l’institution naissante.
Comparing Financing Models for Vocational Education and Training in Botswana, South Africa, and Zimbabwe
Authors: Hondonga Jerald , Ramaligela Sylvia Manto
Published: October 2019

Funding for vocational skills development is important for effective development of graduate competencies. A comparison of literature on funding models in Botswana, SA, and Zimbabwe reveals common models with alternatives augmenting predominant systems. Funding in the three countries is predominantly through public funding and levy-grant system. Other funding sources include income generating activities, corporate and donor funding, fees from students and student grant-loan schemes. Some challenges in TVET funding include fragmented financing systems, general high cost of financing TVET, lack of commitment by stakeholders, poor image of TVET against academic education, inadequate public budgetary allocations by most governments, lack of research and feedback to TVET planners from labour market to allow planning and adjusting funding models for future skilled manpower requirements. There is need to have adequate funding to ensure that graduates fully gain the necessary competencies.
Apprenticeships as a way of Tackling Skills Gaps
Authors: Gatt Suzanne
Published: October 2019

Malta did not suffer the 2009 economic crisis like other EU Member States. Youth unemployment remained low, and the country was among the first registering economic growth. However, Malta still has a very high percentage of early school leavers and is experiencing a significant skills gap in its labour market. In addition, a Cedefop study forecasted job growth mainly at professional and medium-level qualifications. This chapter is a discussion of how Malta is tackling the skills gap challenge by reforming its apprenticeship schemes. As changes were made to the format and governance of apprenticeships, the schemes were extended to more sectors as well as reflected a more modern approach to learning. As the number of apprenticeships continue to grow, Malta hopes to both be able to keep more young people in school through VET as well as provide a better trained skilled workforce to ensure further economic growth. This chapter can serve as an example for other countries and regions intending to reform their apprenticeship schemes.
Global Sustainable Supplier Selection
Authors: Awasthi Anjali , Gold Stefan
Published: October 2019

Supplier selection is critical for sustainability management in global supply chains. In this chapter, the authors present a content analysis based literature review for global sustainable supplier selection. The supplier selection is investigated along four dimensions, namely economic, environmental, social, and global. The results of the study yield that environmental and social criteria are often used together for supplier selection whereas global risk criteria are rarely used, even less as we move along multiple tiers of the supply chain. From the review, the authors also identified the top criteria along these four dimensions for global sustainable supplier selection. Along the economic dimension, the top three criteria are quality, cost, and general supplier characteristics. The social dimension has employees, transparency and engagement, and local communities' influence as the top criteria. Along the environmental dimension, the top criteria are pollution and hazardous emissions, standards and management systems, green product and design, and green competencies and processes. The top criteria along the global dimension are distance, other risks, and politics and economy.
Impact of Cloud Computing on Green Supply Chain Management
Authors: Khasawneh Mohammed A.
Published: October 2019

Almost every market in the world aims to go globally as wide as possible. It is important to understand the need for information and internet merged together in order to achieve such goal. Cloud systems are the new way of delivering and managing information to different parts in the world in a secure manner. However, not many organizations have moved to cloud. The rely of green supply chain management systems on cloud is not as popular as expected and not increasing fast enough. There is a trust issue raised against cloud and the adoption to it. Cloud can bring different benefits to green supply chain management systems such as the low cost of running, speed of dealing with information, and information availability which can have significant impact on energy savings. Organization contribution in the process of moving to cloud is important to attach any knowledge database to take competitive advantage.
