Published: April 2020

Semen quality assessment is a prime prerequisite for any breeding programme. Computer-Assisted Sperm Analyzer (CASA) can measure the semen quality very accurately and sharply. The research was conducted at American Dairy Limited (ADL) at Vangnahati, Sreepur, Gazipur. A total of 120 ejaculates were collected from three genetic groups of bucks namely Black Bengal (BB), Boer and Jamunapari (JP) with a view to characterize and compare the semen motility and velocity parameters using Computer- Assisted Sperm Analyser. Significantly (p<0.05) higher ejaculate volume was found in Boer buck (1.73±0.16 ml) with the lower in BB buck (0.98±0.14), respectively. But significantly (p<0.05) higher total, forward progressive and fast motility was found in BB (55.47±3.17, 47.23±2.74 and 37.62±2.40%) and lower in JP (40.67±3.37, 30.97±2.91 and 21.81±2.55%), respectively. Significantly (p<0.01) fastest straight line and average path distance was observed in Boer bucks (12.29±1.63 and 15.89±1.95 μm) than Black Bengal and Jamunapari bucks (4.38±1.19 and 7.26±1.57; and 3.14±1.27 and 8.42±1.95 μm), respectively. The distance curved line (DCL) and distance straight line (DSL) was significantly (p<0.05) higher in Boer (29.13±4.87, 12.29±1.63 and 15.89±1.95 _m/sec) and lower in BB (22.07±4.36 and 7.26±1.57 _m/sec), respectively. In case of curvilinear velocity, straight line velocity and average path velocity value was significantly (p<0.01) higher in Boer (127.08±13.88, 50.01±7.68 and 68.13±7.25 _m/sec) with lower in JP (62.01±12.77, 15.75±7.35 and 22.39±9.42) where as linearity and straightness was higher in Boer and lower in BB (p>0.05), respectively. The scrotal circumference had positive correlations with semen volume and curvilinear velocity for all the genotypes. It was concluded that semen of Boer bucks found consistently better than other two genetic groups of bucks. Further, competitive studies with large sample may be performed to evaluate the breed specific differences in available goat breeds. I think this study also disclosed the some rare parameters of semen quality by using Computer-Assisted Sperm Analyzer which was impossible in manually. These results of the present study could be an authentic guideline in future performance tests of different genetic groups of bucks.

Published: April 2020

An experiment was conducted to evaluate the efficacy of AZOMITE® as source of natural minerals on growth performance of commercial broiler. A total of 1,020 day-old Cobb 500 male broiler chicks were randomly allocated to 5 dietary treatments with 6 replications per treatment having 34 chicks in each pen. The five dietary treatments were: (i) basal diet without AZOMITE®, (ii) basal diet with 0.25% AZOMITE®, (iii) basal diet with 0.50% AZOMITE® which was recommended by manufacturer, (iv) basal diet with 0.75% AZOMITE® and (v) basal diet with 1.0% AZOMITE®. Broilers were reared in open-sided gable type house for a period of 32 days. Results showed that the supplementation of AZOMITE® had significant effect on growth performance (p<0.01) of broilers. Live body weight (LBW), body weight gain (BWG), average daily gain (ADG), feed intake (FI), feed conversion ratio (FCR), European efficiency factor (EEF) and gain cost of the birds fed various levels of AZOMITE® were significantly improved as compared to the control. Meat characteristics results indicated that the treatments had no significant effect on dressing percent, thigh, drumsticks and breast percentage among the dietary groups. Taken together, it may be concluded that the supplementation of AZOMITE® in commercial broiler at 0.50 to 1.0% improved live weight, feed intake and feed conversion ratio of commercial broilers.

Reclaiming physician identity: It’s time to integrate ‘Doctor as Person’ into the CanMEDS framework
Authors: Dagnone Jeffery Damon , Glover Takahashi Susan , Whitehead Cynthia , Spadafora Salvatore 
Published: April 2020

In 1996, the Royal College of Physicians & Surgeons of Canada (RCPSC) adopted the CanMEDS framework with seven key roles: medical expert, communicator, collaborator, health advocate, manager, professional, and scholar. For many years, CanMEDS has been recognized around the world for defining what patients need from their physicians. From the start, the RCPSC acknowledged that these roles should evolve over time to continue to meet patient and societal needs (updates in 2005 & 2015). We propose that an 8th role is now needed in the framework: “Doctor as Person”. Interestingly, this role was present in the foundational work through the Educating Future Physicians for Ontario (EFPO) project that the RCPSC drew upon in creating CanMEDS more than 20 years ago. Given today’s challenges of providing care in an increasingly stressed Canadian healthcare system, physicians are struggling more than ever with health and wellness, burnout, and the deterioration of the clinical environment. From the patient perspective, there is growing concern that physician-patient interactions are becoming increasingly impersonal and decreasingly patient-centered. The crack emerging in the foundation of physician identity needs to be remedied. We need to pay close attention to how we define ourselves as physicians, by better identifying the competencies required to navigate the personal and professional challenges we face. Only in so doing can we ward off the threat that exists in losing authentic human to human care interactions. Formalizing Doctor as Person as an 8th role in the CanMEDS framework will help patients and physicians create the space to have essential conversations about the humanity of medical care.

Published: April 2020

Nowadays “Internet of Things” or IoT becomes the most popular technology in the Internet system. Types of devices and sensors have been connected as a network of devices and sensors. While a wireless sensor network is a traditional network of sensors that can be considered as a beginning point of IoT systems. Currently, these sensor data are not only exchanged within a local network but also are delivered to other devices in the Internet. Consequently, well-known organizations such as IEEE, IETF, ITU-T and ISO/IET are trying to set standards for wireless sensor devices in IoT systems. The recommended standard utilizes many of internet stack standards such as CoAP, UDP and IP. However, the traditional design of WSNs is to avoid using internet protocol in the system to reduce transmission overhead and power consumption due to resource limitation. Fortunately, the current technology in both hardware and software allow the internet standard to sufficiently operate in a small sensor. In this paper, we propose a MAC protocol named CU-MAC to efficiently support IoT standard that need request-respond communication or bi-direction communication. CU-MAC uses multi-channel communication to perform continuous and bi-directional data transfer at low duty-cycle. It also has a mechanism to overcome the hidden terminal problem. We evaluated the performance of CU-MAC on both simulation and real testbed based on Contiki OS. The result shows that CU-MAC outperforms other existing MAC protocols in term of packet delivery ratio at 98.7% and requires lower duty-cycle than others to operate in the high traffic environment.

Abstract
Characterizing the physical properties and compositions of circumplanetary disks can provide important insights into the formation of giant planets and satellites. We report Atacama Large Millimeter/submillimeter Array 0.88 mm (Band 7) continuum observations of six planetary-mass (10–20 M
Jup) companions: CT Cha b, 1RXS 1609 b, ROXs 12 b, ROXs 42B b, DH Tau b, and FU Tau b. No continuum sources are detected at the locations of the companions down to 3σ limits of 120–210 μJy. Given these nondetections, it is not clear whether disks around planetary-mass companions indeed follow the disk-flux–host-mass trend in the stellar regime. The faint radio brightness of these companion disks may result from a combination of fast radial drift and a lack of dust traps. Alternatively, as disks in binary systems are known to have significantly lower millimeter fluxes due to tidal interactions, these companion disks may instead follow the relationship of moderate-separation binary stars. This scenario can be tested with sensitive continuum imaging at rms levels of ≲10 μJy.
H- and Dissociation in Ultra-hot Jupiters: A Retrieval Case Study of WASP-18b
Authors: Gandhi Siddharth , Madhusudhan Nikku , Mandell Avi 
Published: April 2020

Abstract
Atmospheres of a number of ultra-hot Jupiters (UHJs) with temperatures ≳2000 K have been observed recently. Many of these planets show largely featureless thermal spectra in the near-infrared observed with the HST WFC3 spectrograph (1.1–1.7 μm) even though this spectral range contains strong H2O opacity. Recent works have proposed the possibility of H- opacity masking the H2O feature and/or thermal dissociation of H2O causing its apparent depletion at the high temperatures of UHJs. In this work, we test these hypotheses using observations of the exoplanet WASP-18b as a case study. We report detailed atmospheric retrievals of the planet using the HyDRA retrieval code, extended to include the effects of H- opacity and thermal dissociation. We report constraints on the H2O, CO, and H- abundances as well as the pressure–temperature profile of the dayside atmosphere for retrievals with and without H-/dissociation for each data set. We find that the H2O and H- abundances are relatively unconstrained given the featureless WFC3 spectra. We do not conclusively detect H- in the planet, contrary to previous studies that used equilibrium models to infer its presence. The constraint on the CO abundance depends on the combination of WFC3 and Spitzer data, ranging from solar to super-solar CO values. We additionally see signs of a thermal inversion from two of the data sets. Our study demonstrates the potential of atmospheric retrievals of UHJs, including the effects of H- and thermal dissociation of molecules.

Abstract
We report 370 measures of 170 components of binary and multiple-star systems, obtained from speckle imaging observations made with the Differential Speckle Survey Instrument at Lowell Observatory’s Discovery Channel Telescope in 2015 through 2017. Of the systems studied, 147 are binary stars, 10 are seen as triple systems, and 1 quadruple system is measured. Seventy-six high-quality nondetections and 15 newly resolved components are presented in our observations. The uncertainty in relative astrometry appears to be similar to our previous work at Lowell, namely, linear measurement uncertainties of approximately 2 mas, and the relative photometry appears to be uncertain at the 0.1–0.15 mag level. Using these measures and those in the literature, we calculate six new visual orbits, including one for the Be star 66 Oph and two combined spectroscopic–visual orbits. The latter two orbits, which are for HD 22451 (YSC 127) and HD 185501 (YSC 135), yield individual masses of the components at the level of 2% or better, and independent distance measures that in one case agrees with the value found in the Gaia DR2 and in the other disagrees at the 2σ level. We find that HD 22451 consists of an F6V+F7V pair with orbital period of 2401.1 ± 3.2 days and masses of 1.342 ± 0.029 and

. For HD 185501, both stars are G5 dwarfs that orbit one another with a period of 433.94 ± 0.15 days, and the masses are 0.898 ± 0.012 and

Abstract
We compare the mass functions of young star clusters (ages ≤ 10 Myr) and giant molecular clouds (GMCs) in six galaxies that cover a large range in mass, metallicity, and star formation rate (LMC, M83, M51, NGC 3627, the Antennae, and NGC 3256). We perform maximum-likelihood fits of the Schechter function,

, to both populations. We find that most of the GMC and cluster mass functions in our sample are consistent with a pure power-law distribution (

). M51 is the only galaxy that shows some evidence for an upper cutoff (M

PL = −2.3 ± 0.3 for our GMC sample and β
PL = −2.0 ± 0.3 for the cluster sample. This result, that

Abstract
A comprehensive analysis of plasma and composition characteristics inside magnetic clouds (MCs) observed by the Advanced Composition Explorer spacecraft from 1998 February to 2011 August is presented. The results show that MCs have specific interior structures, and MCs of different speeds show differences in composition and structure. Compared with the slow MCs, fast MCs have enhanced mean charge states of iron, oxygen, silicon, magnesium,

,

, and

values. For ionic species in fast MCs, a higher atomic number represents a greater enhancement of mean charge state than slow MCs. We also find that both the fast and slow MCs display bimodal structure distribution in the mean iron charge state (

), which suggests that the existence of flux rope prior to the eruption is common. Furthermore, the

,

, and

ratio distribution inside fast MCs have the feature that the posterior peak is higher than the anterior one. This result agrees with the “standard model” for coronal mass ejection/flares, by which magnetic reconnection occurs beneath the flux rope, thereby ionizing the ions of the posterior part of the flux rope sufficiently by high-energy electron collisions or by direct heating in the reconnection region.
Why Is it So Cold in Here? Explaining the Cold Temperatures Retrieved from Transmission Spectra of Exoplanet Atmospheres

Published: April 2020

Abstract
Transmission spectroscopy is a powerful technique widely used to probe exoplanet terminators. Atmospheric retrievals of transmission spectra are enabling comparative studies of exoplanet atmospheres. However, the atmospheric properties inferred by retrieval techniques display a significant anomaly: most retrieved temperatures are far colder than expected. In some cases, retrieved temperatures are

colder than

. Here, we provide an explanation for this conundrum. We demonstrate that erroneously cold temperatures result when 1D atmospheric models are applied to spectra of planets with differing morning–evening terminator compositions. Despite providing an acceptable fit, 1D retrieval techniques artificially tune atmospheric parameters away from terminator-averaged properties. Retrieved temperature profiles are hundreds of degrees cooler and have weaker temperature gradients than reality. Retrieved abundances are mostly biased by

and sometimes by

, with the most extreme biases for ultra-hot Jupiters. When morning–evening compositional differences manifest for prominent opacity sources, H2O abundances retrieved by 1D models can be biased by over an order of magnitude. Finally, we demonstrate that these biases provide an explanation for the cold retrieved temperatures reported for WASP-17b and WASP-12b. To overcome biases associated with 1D atmospheric models, there is an urgent need to develop multidimensional retrieval techniques.
Solar Disk Center Shows Scattering Polarization in the Sr i 4607 Å Line

Abstract
Magnetic fields in turbulent, convective high-β plasma naturally develop highly tangled and complex topologies—the solar photosphere being the paradigmatic example. These fields are mostly undetectable by standard diagnostic techniques with finite spatio-temporal resolution due to cancellations of Zeeman polarization signals. Observations of resonance scattering polarization have been considered to overcome these problems. But up to now, observations of scattering polarization lack the necessary combination of high sensitivity and high spatial resolution in order to directly infer the turbulent magnetic structure at the resolution limit of solar telescopes. Here, we report the detection of clear spatial structuring of scattering polarization in a magnetically quiet solar region at disk center in the Sr i 4607 Å spectral line on granular scales, confirming theoretical expectations. We find that the linear polarization presents a strong spatial correlation with the local quadrupole of the radiation field. The result indicates that polarization survives the dynamic and turbulent magnetic environment of the middle photosphere and is thereby usable for spatially resolved Hanle observations. This is an important step toward the long-sought goal of directly observing turbulent solar magnetic fields at the resolution limit and investigating their spatial structure.
De la « Belle bataille » à l’art de la guerre
Authors: Faudais Stéphane , Cotard Jean-Luc 
Published: April 2020

Le langage commun utilise le terme de « belle bataille » pour caractériser des affrontements dans le domaine politique, social… Or cette terminologie est peu utilisée par les militaires, qui ont conscience de l’oxymore de l’expression. Ils insistent plus sur le raisonnement, qui permet de donner un sens à l’action puis d’organiser les moyens en fonction des circonstances, sur la simplicité de l’idée qui offre une compréhension aisée par tous et l’adaptation de tous. Cette logique sert en fait à découvrir ce qu’est l’art de la guerre et à aborder rapidement la formation par maturation des officiers de l’armée de terre pour le pratiquer.
