The experiment was conducted to know the effect of chicken manure doses and nitrogen fertilizers on growth and yield of lettuce (Lactuca sativa L). The experiment was conducted at Kutawaringin Village, Selajambe District, Kuningan, West Java Province, from March until May 2018. The experimnetal design was used Randomized Completely Block Design (RBD) with factorial pattern. Each treatment was repeated three times. The treatment consisted two factors. The first factor was ratesÂ of chicken manure that consisted four levels : K1 (0 ton/ha), K2 (10 ton/ha), K3 (20 ton/ha), K4 (30 ton/ha), while the second factor was nitrogen fertilizers rates which consist three levels : N1 (77 kg/ha), N2 (100 kg/ha), N3 (123 kg/ha). The result showed that there was an interaction effect between chicken manure doses and nitrogen fertilizers on root volume (28 days after planting), total weight per plant, total weight per plot, and total biomass. Independently, chicken manure doses gave significant effect of plant high, number of leafs, leaf area, relative growth rates (28 and 35 days after planting). While nitrogen fertilizers rates effected plant height, number of leaves, leaf area, net assimilation rates (21 days after planting), relative growth rate (21 and 28 days after planting), root volume (35 days after planting). Chicken manure doses 20 ton/ha and nitrogen fertilizers doses 123 kg/ha gave the best result on total weight per plant and per plot which produces 30,56 g per plant and 638,38 g per plot (2,5 ton/ha).

Rosuvastatin calcium is a salt form of rosuvastatin with antilipidemia activity. Rosuvastatin Calcium classified in class two of Biopharmaceutics Clasification System (BCS) has low solubility in water (17.96 mg / L) and high permeability. Based on this, rosuvastatin calcium needs to be formulated appropriately in order to produce high bioavailability and maximum therapeutic effect. The bioavailability of BCS 2 drug is determined by the dissolution rate of the drug in gastrointestinal fluid so that a technique is needed in formulating the drug. This study aims to develop a formulation technique for rosuvastatin calcium tablets through liquisolid technique and formation of inclusion complexes with β-cyclodextrin in order to increase the rate of dissolution. Tablet formulation with liquisolid technique was made with a concentration of 10% rosuvastatin calcium in propylene glycol, with a ratio of US2® (carrier) and Aerosil 200 (coating) made with a ratio of 10: 1 and 20: 1. In addition to the formulation with liquisolid technique, formulations were also carried out with the complex inclusion technique of rosuvastatin calcium-β-cyclodextrin using kneading method and freeze drying method with a mol ratio of 1: 1 and 1: 2. The liquisolid system and inclusion complexes formed were characterized using FTIR and SEM. Characterization results indicated changes in the form of polymorphous rosuvastatin calcium. Tablet formulations were made by direct compression using a liquisolid system and an inclusion complex equivalent to 10 mg of rosuvastatin calcium. Based on the results of the ANOVA statistical test and further LSD tests showed that calcium rosuvastatin tablets made with liquisolid and inclusion complexes can increase the dissolution rate compared to pure rosuvastatin calcium tablets and inovator rosuvastatin calcium tablets. The highest dissolution rate was produced by liquisolid R20: 1 tablet at 60 minutes at 85.53 ± 1.02% in an enzyme-free simulated gastric fluid dissolution medium and 110.02 ± 1.71% in an enzyme-free simulated intestinal fluid dissolution medium.

How do Ontario family medicine residents perform on global health competencies? A multi-institutional survey
Authors: Veras Mirella , Pottie Kevin , Ramsay Tim , Welch Vivian , Tugwell Peter 
Published: April 2020

Background: There is an increased interest in global health among medical students, family medicine residents, and medical educators. This paper is based on research to assess confidence in knowledge and skills in global health in family medicine residents in five universities across Ontario. Methods: A web based survey was sent to 166 first-year family medicine residents from five universities within Ontario. Descriptive statistics were used to analyze residents’ confidence in their knowledge and skills in global health. The strength of association between each of the self-perceived knowledge and skills variables was assessed by the Spearman correlation coefficient. Results: The response rate ranged from 29% to 66% across the five universities. Self-perceived knowledge scores revealed that 34.3% of the respondents were very confident, 51.9% were somewhat confident, and 13.8% were not at all confident about their global health knowledge. Participants' confidence scores were lower in relation to knowledge of access to health care for low income nations (44.3%), and were better on their global health skills related to working in a team (70.9%) and listening actively to patients' concerns (64.6%). Conclusions: The global health competency scale has identified key areas of strengths and weaknesses of family medicine programs in global health education. This can be used to evaluate and analyze progress over time.

Abstract
The Open Cluster Chemical Abundances and Mapping (OCCAM) survey aims to constrain key Galactic dynamical and chemical evolution parameters by the construction of a large, comprehensive, uniform, infrared-based spectroscopic data set of hundreds of open clusters. This fourth contribution from the OCCAM survey presents analysis using Sloan Digital Sky Survey/APOGEE DR16 of a sample of 128 open clusters, 71 of which we designate to be “high quality” based on the appearance of their color–magnitude diagram. We find the APOGEE DR16 derived [Fe/H] abundances to be in good agreement with previous high-resolution spectroscopic open cluster abundance studies. Using the high-quality sample, we measure Galactic abundance gradients in 16 elements, and find evolution of some of the [X/Fe] gradients as a function of age. We find an overall Galactic [Fe/H] versus R
GC gradient of −0.068 ± 0.001 dex kpc−1 over the range of 6 < R
GC < 13.9 kpc; however, we note that this result is sensitive to the distance catalog used, varying as much as 15%. We formally derive the location of a break in the [Fe/H] abundance gradient as a free parameter in the gradient fit for the first time. We also measure significant Galactic gradients in O, Mg, S, Ca, Mn, Cr, Cu, Na, Al, and K, some of which are measured for the first time. Our large sample allows us to examine four well-populated age bins in order to explore the time evolution of gradients for a large number of elements and comment on possible implications for Galactic chemical evolution and radial migration.
Forward Modeling the Orbits of Companions to Pulsating Stars from Their Light Travel Time Variations

Published: April 2020

Abstract
Mutual gravitation between a pulsating star and an orbital companion leads to a time-dependent variation in path length for starlight traveling to Earth. These variations can be used for coherently pulsating stars, such as the δ Scuti variables, to constrain the masses and orbits of their companions. Observing these variations for δ Scuti stars has previously relied on subdividing the light curve and measuring the average pulsation phase in equally sized subdivisions, which leads to undersampling near periapsis. We introduce a new approach that simultaneously forward models each sample in the light curve and show that this method improves upon current sensitivity limits—especially in the case of highly eccentric and short-period binaries. We find that this approach is sensitive enough to observe Jupiter mass planets around δ Scuti stars under ideal conditions, and use gravity-mode pulsations in the subdwarf B star KIC 7668647 to detect its companion without radial velocity data. We further provide robust detection limits as a function of the signal-to-noise ratio of the pulsation mode and determine that the minimum detectable light travel time amplitude for a typical Kepler δ Scuti is around 2 s. This new method significantly enhances the application of light travel time variations to detecting short-period binaries with pulsating components, and pulsating A-type exoplanet host stars, especially as a tool for eliminating false positives.
Very Slow Rotators from Tidally Synchronized Binaries

Abstract
A recent examination of K2 lightcurves indicates that ∼15% of Jupiter Trojans have very slow rotation (spin periods P
s > 100 hr). Here we consider the possibility that these bodies formed as equal-size binaries in the massive outer disk at ∼20–30 au. Prior to their implantation as Jupiter Trojans, tight binaries tidally evolved toward a synchronous state with P
s ∼ P
b, where P
b is the binary orbit period. They may have been subsequently dissociated by impacts and planetary encounters with at least one binary component retaining its slow rotation. Surviving binaries on Trojan orbits would continue to evolve by tides and spin-changing impacts over 4.5 Gyr. To explain the observed fraction of slow rotators, we find that at least ∼15%–20% of outer disk bodies with diameters 15 < D < 50 km would have to form as equal-size binaries with 12 ≲ a
b/R ≲ 30, where a
b is the binary semimajor axis and R = D/2. The mechanism proposed here could also explain very slow rotators found in other small-body populations.
Gamma-Ray Burst Spectrum with a Time-dependent Injection Rate of High-energy Electrons

Published: April 2020

Abstract
Although the physical origin of prompt emission in gamma-ray bursts (GRBs) remains inconclusive, previous studies have considered the synchrotron radiation of relativistic electrons as a promising mechanism. These works usually adopted an invariable injection rate of electrons (Q) which may be discordant with that in a Poynting-flux-dominated jet. In a Poynting-flux-dominated jet (e.g., internal-collision-induced magnetic reconnection and turbulence model), the number of magnetic reconnections occurring simultaneously may grow rapidly with time and result in an increase of Q with time. This paper is dedicated to studying the synchrotron radiation spectrum in this scenario. It is found that the radiation spectrum would obviously get harder if an increasing Q is adopted and a Band-like radiation spectrum can be obtained if the increase of Q is fast enough. The latter is related to the fact that a bump shape rather than a power-law spectrum appears in the low-energy regime of the obtained electron spectrum. This effect can strongly harden the low-energy radiation spectrum. It indicates that an increasing Q can help to alleviate the “fast-cooling problem” of synchrotron radiation for GRBs. Our studies also reveal that a Poynting-flux dominated jet with a large emission radius, a short magnetic reconnection region length, or an injected electron with low minimum energy would prefer to form a Band-like radiation spectrum. We suggest that the Band spectrum found in GRBs may be the synchrotron emission of the electrons with a bump-shape distribution in its low-energy regime.
Dramatiser l’histoire avec Michel Foucault : un “irrationalisme esthétisant” ?
Authors: Sforzini Arianna 
Published: April 2020

Peut-on utiliser la dimension théâtrale pour penser les généalogies de Michel Foucault ? Quelle est la valeur de vérité d’une histoire qui affirme être une « fiction » et procède par scènes, personnages, « dramatiques de la vérité » ? Pour répondre à ces interrogations, le présent article utilise la notion de théâtre dans un sens anti-représentatif et expérientiel : comme un mouvement toujours recommencé d’action et de transformation. En questionnant les critiques de la méthode foucaldienne formulées par des historiens tels que Carlo Ginzburg et Hayden White, nous montrerons comment Foucault mobilise dans ses textes une pensée-théâtre historique qui joue comme une arme de problématisation ironique des grands mythes de l’histoire elle-même. Le théâtre est pour Foucault un instrument pour mener une réflexion historico-politique sur la vérité en dehors des catégorisations et des moralisations traditionnelles de la philosophie et de la science occidentales. Mais la dramatisation philosophique du discours historique opérée par Foucault ne représente-elle pas alors le risque concret d’un dangereux relativisme intellectuel et politique : l’exemple parfait d’une « rhétorique » de l’histoire, qui sacrifie la vérité à l’efficacité de la parole ?
