Published: August 2020

Introduction: We conducted a national survey to characterize current Canadian procedural skills training in Undergraduate Medical Education (UGME). The goals were to identify the most important procedures students should know upon graduation and assess clinician-educator perceptions regarding implementation of a pre-clerkship procedural program.
Methods: We distributed the survey to physician-educators across Canada’s 17 medical schools. Respondents were directed to an individualized survey that collected demographic data, physician-educator responses on essential procedural skills, as well as physician-educator opinions on the value of a pre-clerkship procedural training program.
Results: The response rate for this survey was 21% (42 out of 201 distributed surveys were completed). The top 10 most important procedures identified by physician-educators included IV Access, Airway Management, Local anesthesia/field block, Casting, Spontaneous Vaginal Delivery, Testing for STIs, Phlebotomy, Suturing of Lacerations, Nasogastric Tube Insertion, and Venipuncture. Physician-educators supported a pre-clerkship procedural program.
Conclusions: Identifying the most crucial procedural skills is the first step in implementing a competency-based procedural skills training program for Canadian medical students. With the list of essential skills, and the support for physician-educators in developing a pre-clerkship procedural skills curriculum, hopefully there can be future development of formalized curricula.

SOME TRENDS IN FRESHWATER TROPICAL AQUACULTURE AND THEIR IMPACT ON STUDIES OF THE CLIMBING PERCH ANABAS TESTUDINEUS (ANABANTIDAE) REPRODUCTIVE BIOLOGY
Authors: Zworykin Dmitry 
Published: August 2020

The dynamics of publication activities devoted to the climbing perch from
1969 to 2018 is analyzed. It is shown that sharp increases in the number
of publications at the turn of the millennium coincide with changes in
international and national strategies for tropical fish aquaculture, focusing
on cultivation of fast-growing native fish species and small farms support.
These programs have led to a surge in applied research and publications on
the climbing perch, as one of the most promising species. Unfortunately, some
of these papers have been published in journals that are unreliable according
to the criteria of contemporary science and contain controversial conclusions.
Certain consequences of these trends are noted and challenges outlined.

The demand for setting up a wireless LAN internet connectivity is almost mandatory for every commercial building, home, company, and educational institutions. With the growing number and height of buildings as well as the number of users, it has become essential to apply new techniques to provide better wireless network services, especially for security issue with many applications used by an attacker that can decrypt the traditional password to use network resources, that’s lead to poor network performance for providing network services for people authorized to use it. All of that is almost a very challenge issue when applying outdated techniques. In this research a wireless network has been created considering a large number of users in a multi-floor building using a new control system which can solve the problems by setting up RADIUS authentication via that wireless network with a webpage that automatically appears to the user immediately after connecting to the wireless radio signal and automatically gaining an IP address, lead user directly to the temporary page asking him for authentication, if the user has the right username and password or even sometimes a code called Voucher, he will get a package assigned to his priority. This technology will eliminate the vulnerability on the wireless connection and the unauthorized user will be discarded from the router, in addition of that authorized users will get authenticated to make better use of network resources.

Abstract
Clusters of galaxies are outstanding laboratories for understanding the physics of supermassive black hole (SMBH) feedback. Here we present the first Chandra, Karl G. Jansky Very Large Array, and Hubble Space Telescope analysis of MACS J1447.4+0827 (z = 0.3755), one of the strongest cool core clusters known, in which extreme feedback from its central SMBH is needed to prevent the hot intracluster gas from cooling. Using this multiwavelength approach, including 70 ks of Chandra X-ray observations, we detect the presence of collimated jetted outflows that coincide with a southern and a northern X-ray cavity. The total mechanical power associated with these outflows (P
cav ≈ 6 × 1044 erg s−1) is roughly consistent with the energy required to prevent catastrophic cooling of the hot intracluster gas (L
cool = 1.71 ± 0.01 × 1045 erg s−1 for t
cool = 7.7 Gyr), implying that powerful SMBH feedback was in place several Gyr ago in MACS J1447.7+0827. In addition, we detect the presence of a radio minihalo that extends over 300 kpc in diameter (P
1.4GHz = 3.0 ± 0.3 × 1024 W Hz−1). The X-ray observations also reveal an ∼20 kpc plumelike structure that coincides with optical dusty filaments that surround the central galaxy. Overall, this study demonstrates that the various physical phenomena occurring in the most nearby clusters of galaxies are also occurring in their more distant analogs.
Time-sequence Spectroscopy of Epsilon CrA: The 518 nm Mg i Triplet Region Analyzed with Broadening Functions
Authors: Rucinski Slavek M. 
Published: August 2020

Abstract
High-resolution spectroscopic observations of the W UMa-type binary ϵ CrA obtained as a time-monitoring sequence on four full and four partial nights within two weeks have been used to derive orbital elements of the system and discuss the validity of the Lucy model for description of the radial-velocity data. The observations had more extensive temporal coverage and better quality than similar time-sequence observations of the contact binary AW UMa. The two binaries share several physical properties and show very similar deviations from the Lucy model: the primary component is a rapidly rotating star almost unaffected by the presence of the secondary component, while the latter is embedded in a complex gas flow and appears to have its own rotation-velocity field, in contradiction to the model. The spectroscopic mass ratio is found to be larger than the one derived from the light-curve analysis, as in many other W UMa-type binaries, but the discrepancy for ϵ CrA is relatively minor, much smaller than for AW UMa. The presence of the complex velocity flows contradicting the assumption of solid-body rotation suggests a necessity of modification to the Lucy model, possibly along the lines outlined by Stȩpień in his concept of energy transfer between the binary components.

Published: August 2020

Abstract
We present a study on the detailed chemical abundances of five new relatively bright r-process-enhanced stars that were initially observed as part of the SDSS/MARVELS pre-survey. These stars were selected, on the basis of their metallicities and carbon abundances, among a total of 60 stars, for high-resolution spectroscopic follow-up as part of the HESP–GOMPA survey (Hanle Echelle SPectrograph—Galactic survey Of Metal Poor stArs). Here we discuss the three new r-I and two new r-II stars found in this survey. We have carried out a detailed abundance analysis for each of these stars, at a resolving power of R ∼ 30,000, and we compare our results to the existing literature. We could measure three of the first r-process-peak elements (Sr, Y, and Zr) in all five stars, while Ba, Ce, Nd, Sm, Eu, and Dy could be detected among the second r-process-peak elements. Thorium could also be detected in one of the targets, which is found to be an actinide-boost star. We have carried out a comparative study among the subpopulations of the r-process-enhanced stars and other stars of the Milky Way halo population to constrain the origin of this class of objects. These bright r-process-enhanced stars provide an excellent opportunity to study the nucleosynthesis history of this population in great detail, and shed light on their chemical-enrichment histories.

Utility of stone volume estimated by software algorithm in predicting success of medical expulsive therapy
Authors: Jain Rajat , Maskal Sara , Milk Jason , Kahn Leonard , Fedrigon III Donald , Sivalingam Sri 
Published: August 2020

Introduction: We sought to assess the accuracy of using stone volume (SV) estimated with a software algorithm as a predictor for stone passage in a trial of medical expulsive therapy (MET).
Methods: We identified patients with ureteral stones discharged from the ER on MET. Patients with infection, non-ureteral stones, or needing immediate surgical intervention were excluded. For each stone, longest dimension (LD) was recorded and SV was estimated by a computed tomography (CT)-based region growing (RG) algorithm and standard ellipsoid formula (EF). Stone passage within 30 days was assessed via electronic chart and followup phone call.
Results: Fifty-one patients were included for analysis (53±16.7 years, 24% female). The mean LD was 4.85±2.02 mm. The mean SV was similar by EF and RG (0.051±0.057cm3 vs. 0.049± 0.052 cm3; p=0.28). Thirty-three (65%) patients passed their stone, while 18 (35%) did not. The mean LD for passed stones vs. failed passage was 4.1±1.7 mm vs. 6.2±1.8 mm (p=0.0002); the mean EF volume was 0.028±0.035 cm3 vs. 0.093±0.066 cm3 (p=0.00007); and the mean volume by RG was 0.028±0.027cm3 vs. 0.088±0.063 cm3 (p=0.00005).
Conclusions: The clinical utility of using SV estimated by software algorithm as a predictor for success of MET has not previously been examined. We demonstrate that spontaneously passed stones had a significantly smaller volume than those requiring intervention. Further prospective studies are needed to validate these findings and establish volume thresholds for probability of stone passage.

Published: August 2020

Non-tuberculous mycobacteria (NTM) are ubiquitous in the environment and worldwide, under certain environmental conditions, they could be responsible for skin diseases or pulmonary lesions. In Ivory Coast, Buruli ulcers endemic country, very little information concerning the epidemiology of NTM in Cote d'Ivoire is known, this ignorance has led to an underestimation of its prevalence in the environment.
Aims: The objective of this study was to characterize strains of environmental mycobacteria in wastewater located in urban areas in Abidjan (Yopougon) Côte d'Ivoire.
Place and Duration of Study: The study was conducted at Yopougon (Selmer). This site is considered to be Buruli ulcer non-endemic zone according to the national program on fight against Buruli ulcer in Côte d’Ivoire. However, all biological aspect of this work was carried out at the Pastor Institute of Côte d’Ivoire.
Methodology: Wastewater samples were collected at the surfaces at Yopougon using the technique described by Britton and Gresson. In the laboratory, these collected samples were treated according to the method described by Stinear et al. and Kankya et al. consisting of decontamination, neutralization followed by culture.
Classification of species was done according to the method described by Runyon and collaborators. Biochemical identification of mycobacteria was done according to the method described by Metchock.
Results: A total of 32 samples were collected, 8 water samples at each sampling site. After decontamination and culture, specimens grew on Lowenstein-Jensen medium after 7 days (at 37°C and 32°C) and revealed small, smooth, nonpigmented colonies. Smears confirmed the presence of variably acid-fast organisms. Biochemical traits of the isolates revealed, colony grown on Middlebrook agar 7H11 (at 37°C and 32°C); catalase (+); agar (+) (at 37°C and 32°C ); citrate (-); mannitol (-).
Conclusion: This work is one of the first study focusing on Mycobacteria in wastewater in Abidjan. The isolation of Mycobacterium sp., an environmental pathogenic organism, supports the hypothesis of possible colonization of urban wastewater by pathogenic mycobacteria. Further studies are needed to verify the involvement of this specie in mycobacterial infections in Côte d'Ivoire.
A new nonlinear extended state observer design for output tracking of uncertain nonlinear systems
Authors: Zhao Zhi‐Liang , Ma Pengjuan , Chen Sen 
Published: August 2020

SummaryIn this article, we develop a new nonlinear extended state observer (ESO) for output tracking of a class of uncertain nonlinear affine systems. Instead of using the linear functions of the error, the nonlinear functions of the properly magnified error are used in the proposed ESO. Compared with the linear ESO, the new ESO allows more accurate estimation and smaller peaking value. We also design an output‐feedback controller based on the proposed nonlinear ESO. The convergence of the new ESO is proved without assuming the boundedness of the system state. It is also proved that under the proposed output‐feedback controller, the system output is capable to track the given reference signal despite a large scope of nonlinear uncertainties. Simulation results illustrate the effectiveness of the new ESO with improved performance.
Thermodynamic analysis of the phase equilibrium of the polystyrene‐poly(vinyl methyl ether) system

Published: August 2020

AbstractThe phase diagrams of polystyrene (PS)‐poly(vinyl methyl ether) (PVME) system obtained via optical interferometry in the study of polymer interdiffusion are presented. The influence of molecular weight of the PS on the position of the binodal curve dome and the critical point is shown. Paired interaction parameters and their temperature dependences are calculated in the framework of Flory‐Huggins theory both for the present experimental diagrams and for the ones, previously obtained by different authors. It is shown that the generalized temperature dependence of the Flory‐Huggins parameter can be used to model phase equilibrium in a wide range of temperatures and compositions. For the first time for PS‐PVME system, the generalized phase state diagram characterized by both lower and upper critical solution temperatures is calculated and constructed.
Enhanced biodiversity and abundance of benthic invertebrate macrofauna in a New Zealand marine reserve

Published: August 2020

Abstract

No‐take marine reserves are an important management tool in the conservation and restoration of marine habitats around the world. They are intended to provide spatial refugia for exploited species and to protect sensitive habitat and biodiversity hot spots.
Despite strong evidence that marine reserves enhance overall biodiversity, it is not clear that this effect extends to all taxonomic groups. Most marine reserves are designed to protect large mobile fauna. Their effect on small sessile benthic invertebrates is unclear, yet these organisms provide critical ecosystem functions.
Three hundred and seventy‐eight images and associated faunal descriptions were compared from 2007 and 2018 in Ulva Island/Te Wharawhara Marine Reserve, Stewart Island/Rakiura, New Zealand (46.9°S, 168.1°E, 0–25 m depth, established 2004), to discern the effect of non‐extractive marine protection on a soft‐sediment temperate benthic community.
Qualitative habitat types observed in the 2018 images were similar to those described in 2007. There was a significant positive effect of protection on benthic invertebrate abundance between 2007 and 2018 across Paterson Inlet/Whaka a Te Wera. Additionally, there were significantly more benthic invertebrates within reserve sites compared with sites outside the reserve in 2018.
Based on these positive effects, it can be concluded that Ulva Island/Te Wharawhara Marine Reserve has facilitated an increase in the biodiversity of the benthic invertebrate community of Paterson Inlet/Whaka a Te Wera, Stewart Island/Rakiura.
Interestingly, heavily calcified biogenic reefs were present within Paterson Inlet/Whaka a Te Wera, but not within the reserve itself. The re‐evaluation of marine reserve boundaries could result in more comprehensive and representative management of the rich marine environment around Stewart Island/Rakiura.

Abstract

Fishing is the greatest source of anthropogenic impact on global marine resources and the ecosystems supporting them. The decline of many fish stocks has led to the need to apply control and protection measures to promote the recovery of these resources.
In the Argentine Sea, a multispecies coastal fishery in the El Rincón region has displayed signs of overexploitation since the beginning of the century. Consequently, temporal and spatial protection measures were implemented in 2004.
In previous studies, an independent stock of Percophis brasiliensis in El Rincón was identified based on the parasite communities of fish caught in 2005. However, no subsequent studies using parasite communities have been performed since the protective fishery closure measures were applied.
To evaluate parasites as indicators of temporal change in the El Rincón stock of P. brasiliensis after the implementation of these protection measures, a sample from 2018 was compared with that from the previous study, as well as with three other samples. Two of the latter (Argentine Common Fishing Zone and San Matías Gulf) corresponded to previously identified independent stocks in the Argentine biogeographical province and the third was a new sample from the Magellanic Province in southern Patagonian waters.
The structure and composition of parasite assemblages of the El Rincón stock of P. brasiliensis differed significantly in 2018, after several years of protective measures. The increased loads observed in several parasite species constitute a promising signal of successful ecosystem recovery. A discrete stock in the Magellanic Province was also identified, providing insights into the population structure of P. brasiliensis along its distributional range, with applications for the sustainable management of this resource.
