Published: August 2022

Dibenzo[g,p]chrysene (DBC), which consists of a twisted naphthalene core with four fused benzene rings, is a promising framework for organic electronic materials. Therefore, the research for structure–property relationships is important for the design of DBC-based materials. Here, the electrochemical and spectroscopic properties of DBC derivatives were investigated, and the effects of substituents and torsion of the naphthalene moiety were examined based on density functional theory (DFT) calculations. All the substituted DBC derivatives showed higher oxidation potentials than that for DBC-H, even for compounds that contained an electron-donating group such as DBC-Me and DBC-SMe. DFT calculations clearly indicate that these higher oxidation potentials are due to the ineffective conjugation of the MeO group, which is oriented perpendicular to the benzene ring because of the steric repulsion of substituents on both sides. More specifically, the inductive effect of the MeO group is dominant rather than the mesomeric effect when the substituent is located at both sides of the MeO group. Concerning the torsion of the naphthalene moiety, the twisting results in a slight increase in the HOMO and a slight lowering of the LUMO. The twisting effect is much smaller than the conjugation effect of the MeO group. Absorption spectra of all the substituted DBC derivatives also showed a red-shift as compared to that for DBC-H. Concerning the luminescence, a strong photoluminescence was observed for DBC-H and DBC-Si.

Alcohol fuels do have some extra benefit compare to other alternative fuels, like the capability to work in existing engines also have the ability to decrease harmful emissions. Among the various alcohols, ethanol is considered most appropriate fuels for SI engines, because of its superior fuel quality and ecological benefits. In this experiment, ethanol was blended in different ratios as 0%, 5%, 10% and 20% with gasoline. The effect of the ethanol/gasoline blends on engine emissions at various compression ratios (CRs) of 10:1, 10.5:1, 11:1 and 11.5:1 was studied and examine by using computerized single cylinder, 4 stroke, multi-fuel, variable CRs engine. Engine emission characteristics are studied experimentally by the combustion of different blends of E0, E5, E10 and E20 at different loads of 0 kg, 1 kg, 2 kg and 3 kg. Result shows that adding ethanol in gasoline engine at CRs of 10:1, 10.5:1, 11:1, and 11.5:1 emission reduces (CO, CO2, NOx except HC). Additionally, CO2 emissions were found lower in E0 at CR 10.5:1 and also at CR 11.5:1 as compared to E5, E10 and E20. Also, it was observed that blended fuel permits varying CRs without any knock occurrence. Finally, octane numbers are found to be higher with ethanol blends.

Rotation of Low-mass Stars in Upper Centaurus–Lupus and Lower Centaurus–Crux with TESS
Authors: Rebull L. M. , Stauffer J. R. , Hillenbrand L. A. , Cody A. M. , Kruse Ethan , Powell Brian P.
Published: August 2022

We present stellar rotation rates derived from Transiting Exoplanet Survey Satellite (TESS) light curves for stars in Upper Centaurus–Lupus (UCL; ∼136 pc, ∼16 Myr) and Lower Centaurus–Crux (LCC; ∼115 pc, ∼17 Myr). We find spot-modulated periods (P) for ∼90% of members. The range of light-curve and periodogram shapes echoes that found for other clusters with K2, but fewer multiperiod stars may be an indication of the different noise characteristics of TESS, or a result of the source selection methods here. The distribution of P as a function of color as a proxy for mass fits nicely in between that for both older and younger clusters observed by K2, with fast rotators being found among both the highest and lowest masses probed here, and a well-organized distribution of M-star rotation rates. About 13% of the stars have an infrared excess, suggesting a circumstellar disk; this is well matched to expectations, given the age of the stars. There is an obvious pileup of disked M stars at P ∼ 2 days, and the pileup may move to shorter P as the mass decreases. There is also a strong concentration of disk-free M stars at P ∼ 2 days, hinting that perhaps these stars have recently freed themselves from their disks. Exploring the rotation rates of stars in UCL/LCC has the potential to help us understand the beginning of the end of the influence of disks on rotation, and the timescale on which stars respond to unlocking.

The radio galaxy M87 is the central dominant galaxy of the Virgo Cluster. Very high-energy (VHE, ≳0.1 TeV) emission from M87 has been detected by imaging air Cherenkov telescopes. Recently, marginal evidence for VHE long-term emission has also been observed by the High Altitude Water Cherenkov Observatory, a gamma-ray and cosmic-ray detector array located in Puebla, Mexico. The mechanism that produces VHE emission in M87 remains unclear. This emission originates in its prominent jet, which has been spatially resolved from radio to X-rays. In this paper, we construct a spectral energy distribution from radio to gamma rays that is representative of the nonflaring activity of the source, and in order to explain the observed emission, we fit it with a lepto-hadronic emission model. We found that this model is able to explain nonflaring VHE emission of M87 as well as an orphan flare reported in 2005.

Parker Solar Probe (PSP) has shown that the solar wind in the inner heliosphere is characterized by the quasi omnipresence of magnetic switchbacks (“switchback” hereinafter), local backward bends of magnetic field lines. Switchbacks also tend to come in patches, with a large-scale modulation that appears to have a spatial scale size comparable to supergranulation on the Sun. Here we inspect data from the first 10 encounters of PSP focusing on different time intervals when clear switchback patches were observed by PSP. We show that the switchbacks modulation, on a timescale of several hours, seems to be independent of whether PSP is near perihelion, when it rapidly traverses large swaths of longitude remaining at the same heliocentric distance, or near the radial-scan part of its orbit, when PSP hovers over the same longitude on the Sun while rapidly moving radially inwards or outwards. This implies that switchback patches must also have an intrinsically temporal modulation most probably originating at the Sun. Between two consecutive patches, the magnetic field is usually very quiescent with weak fluctuations. We compare various parameters between the quiescent intervals and the switchback intervals. The results show that the quiescent intervals are typically less Alfvénic than switchback intervals, and the magnetic power spectrum is usually shallower in quiescent intervals. We propose that the temporal modulation of switchback patches may be related to the “breathing” of emerging flux that appears in images as the formation of “bubbles” below prominences in the Hinode/SOT observations.

​Mangkokan leaves (Nothopanax scutellarium (Burm.f) Merr.) have several properties, containing several chemicals that have bioactivity. It contains flavonoids and is a natural source of antioxidants. This study aims to determine the total flavonoid content and the potency of the ethyl acetate fraction in the leaves of the Mangkokan leaf as an antioxidant in counteracting free radicals. Identification of flavonoids was carried out with a reagent between magnesium powder and concentrated HCl, the orange color formed indicated the presence of flavonoids. Determination of the total flavonoid content of the ethyl acetate fraction of the Mangkokan leaf extract was carried out colorimetrically using a UV-Vis spectrophotometer. The antioxidant activity test of the ethyl acetate fraction of kukukan leaf extract was carried out using the DPPH (1,1-diphenyl-2-picrylhydrazyl) method. The results showed that the total flavonoid content of the ethyl acetate fraction of the Mangkokan leaf extract was 25.402749 mgGAE/g extract and the free radical inhibition test with the DPPH method showed that the ethyl acetate fraction of the Mangkokan leaf extract had antioxidant activity with an IC50 value of 103.36 ppm. The ethyl acetate fraction of the Mangkokan leaf extract has activity as an antioxidant with a moderate category of antioxidant power so that it has the potential to be developed in the treatment of diseases caused by free radicals.
Le poste de la guerre d’Indochine : l’échec de la pacification
Authors: Cadeau Ivan
Published: August 2022

La guerre d’Indochine est marquée de représentations quelque peu faussées. Dans ces dernières, la place occupée par les troupes d’élite – légionnaires et parachutistes, principalement – apparaît prépondérante, tout comme les opérations auxquelles elles ont participé, la bataille de Diên Biên Phu en premier lieu. Pourtant, ces grands engagements restent relativement rares et il est possible d’affirmer que la guerre d’Indochine a d’abord été une guerre de postes. Utilisé de manière générique, le mot « poste » renvoie cependant à des réalités bien différentes. Rien de commun, en effet, entre la tour de garde et le poste accueillant une garnison d’une centaine d’hommes, ou entre le « poste kilométrique » et le blockhaus de la ligne de Lattre. Pourtant, chacune de ces fortifications participe de la politique de pacification mise en place par le commandement français. Celle-ci, contrairement à la pacification pratiquée au temps de la période coloniale (par les généraux Gallieni et Pennequin) s’avère un échec. Du fait de la prise en main et de l’encadrement idéologique des populations par le Viêt-Minh, celles-ci échappent progressivement à l’influence des Français.
De la pacification à la contre-insurrection, la recherche d’une méthode : Cambodge, 1946-1953
Authors: Maloux Thierry
Published: August 2022

Cet article propose une réflexion sur les méthodes de « pacification » utilisées sur le théâtre cambodgien pendant la guerre d’Indochine. Il s’inscrit dans le champ des études menées sur la guerre « au milieu des populations », en examinant la singularité des approches khmère, vietnamienne et française. Il décrit la succession des expériences entreprises pour contrôler les populations en se concentrant sur la méthode du regroupement, de l’organisation de l’auto-défense et de l’action de propagande. Il tente de démontrer l’importance de la complémentarité des facteurs politiques et militaires et ses conséquences en termes d’action psychologique. Ainsi, les expériences du théâtre cambodgien inspireront les principes de la doctrine française de guerre contre-insurrectionnelle.
1952 : une lueur d’espoir sur le front de la pacification en Indochine
Authors: Le Page Jean-Marc
Published: August 2022

En 1952 le corps expéditionnaire français en Extrême-Orient se trouve dans une impasse. Le Nord-Vietnam subit les coups des éléments vietminh infiltrés dans le Delta. La politique de pacification mise en œuvre jusque-là ne permet pas aux Franco-Vietnamiens de reprendre la main. Dans ce contexte le général de Linarès, commandant les troupes du Tonkin, met en œuvre un nouveau plan de pacification qui conjugue des opérations militaires à une action administrative et politique menée par les autorités vietnamiennes. Les innovations sont nombreuses ; GAMO, milices, bataillons légers… En même temps les forces françaises mettent en place un bureau de guerre psychologique et des organismes de liaisons avec les autorités vietnamiennes. Elles entament un nouveau cycle dans lequel la France n’est plus au centre du jeu politique mais laisse la place au gouvernement vietnamien.
Le même nous . Identité et réminiscence chez Condillac
Authors: Frigo Alberto
Published: August 2022

Dans l’ Essai sur l’origine des connaissances humaines , Condillac propose une doctrine de la réminiscence fort originale, mais qui n’est pas dépourvue de difficultés. Pour rendre raison de ces difficultés, il convient de revenir sur les sources des thèses de Condillac, et notamment sur ses sources cartésiennes, qui doublent l’influence bien connue de l’ Essay de Locke. On verra ainsi que l’analyse condillacienne de la réminiscence constitue un jalon essentiel dans la postérité du cogito cartésien, et cela notamment à propos de la double interrogation sur l’ unité et l’ identité du moi qui caractérise la réception du cogito à partir de la fin du xvii e  siècle.
On a non-Newtonian fluid type equation with variable diffusion coefficient
Authors: Zhan Huashui , Zhi Yuan , Niu Xiaohua
Published: August 2022

Since the non-Newtonian fluid type equations arise from a broad and in-depth background, many research achievements have been gained from 1980s. Different from the usual non-Newtonian fluid equation, there is a nonnegative variable diffusion in the equations considered in this paper. Such a variable diffusion reflects the characteristic of the medium which may not be homogenous. By giving a generalization of the Gronwall inequality, the stability and the uniqueness of weak solutions to the non-Newtonian fluid equation with variable diffusion are studied. Since the variable diffusion may be degenerate on the boundary $ \partial \Omega $, it is found that a partial boundary value condition imposed on a submanifold of $ \partial\Omega\times (0, T) $ is enough to ensure the well-posedness of weak solutions. The novelty is that the concept of the trace of $ u(x, t) $ is generalized by a special way.
En coup de sabre morphea: An uncommon condition in Africa
Authors: Makhakhe Lehlohonolo , Dlova Ncoza , Smith Annette , Du Preez Michelle
Published: August 2022

The term en coup de sabre morphea refers to a lesion of linear morphea typically located in the frontoparietal scalp and/or the paramedian forehead, often resembling a strike with a sword. In literature, en coup de sabre morphea and en coup de sabre scleroderma are terms used interchangeably and synonymously. Due to the rarity of this condition, treatment is largely based on case report series, leaving much room for speculation in terms of drugs of choice, duration of treatment and dosages. Although typically leaving behind notable and often permanent skin pigmentary changes and indentation of the affected areas, this condition usually remits spontaneously, even in the absence of active form of treatment. The disease severity and prognosis vary according to the subtype: circumscribed morphea has a generally more benign course when compared with linear scleroderma and generalised morphea.
Overview of GEM surficial geochemistry and indicator mineral surveys and case studies in northern Canada

As part of the Geo-mapping for Energy and Minerals (GEM) program between 2008 and 2020, the Geological Survey of Canada carried out reconnaissance-scale to deposit-scale geochemical and indicator mineral surveys and case studies across northern Canada. In these
studies, geochemical methods were used to determine the concentrations of 65 elements in lake sediment, stream sediment, stream water, lake water and till samples across approximately 1,000,000 km2 of northern Canada. State-of the-art indicator methods were used to examine the indicator mineral
signatures in regional-scale stream sediment and till surveys. This research identified areas with anomalous concentrations of elements and/or indicator minerals that are indicative of bedrock mineralization, developed new mineral exploration models and protocols, trained a new generation of
geoscientists and transferred knowledge to northern communities. The most immediate impact of the GEM surveys has been the stimulation of mineral exploration in Canada's north, focussing exploration efforts into high mineral potential areas identified in GEM regional-scale surveys. Regional- and
deposit-scale studies demonstrated how transport data (till geochemistry, indicator minerals) and ice flow indicator data can be used together to identify and understand complex ice flow and glacial transport. Detailed studies at the Izok Lake, Pine Point, Strange Lake, Amaruq deposits and across
the Great Bear Magmatic Zone demonstrate new suites of indicator minerals that can now be used in future reconnaissance- and regional-scale stream sediment and till surveys across Canada.

Let

G

be the first Grigorchuk group. We show that the commutator width of

G

is

2

: every element

g\in [G,G]

is a product of two commutators, and also of six conjugates of

a

. Furthermore, we show that every finitely generated subgroup

H\leq G

has finite commutator width, which however can be arbitrarily large, and that

G

contains a subgroup of infinite commutator width. The proofs were assisted by the computer algebra system GAP.

Nonconventional clinical presentations of diseases are common in older adults. Even dramatic events, such as foreign body (FB) inhalation, can occur in a subtle and non-specific manner. Pill aspiration is a rare yet overlooked cause of airway injury. It accounts for approximately 7% of all FB aspirations. In contrast, oral dysphagia and polypharmacology, mainly administrated in solid oral dosage forms (SDOF), like tablets and pills, are common conditions in older adults. Herein, we present a case of SDOF aspiration in a 78-year-old man. FB inhalation developed with general clinical deterioration and neurological impairment (delirium) rather than overt respiratory symptoms. Bronchoscopy provided remarkable images of this unexpected finding. Caregivers and healthcare workers must be aware of the risk of SDOF aspiration and adopt proper safety measures. Early recognition and bronchoscopy for diagnostic and therapeutic purposes can be lifesaving in such cases.

Published: August 2022

The article examines the role and importance of information competence. The main attention is paid to the analysis of the teaching experience of university teachers from different European countries, a set of courses and disciplines that are offered for use in the training of culturologists and art critics. Accordingly, the purpose of the work is to analyze the features of the formation of information competence among specialists in culture and arts in the process of professional training in higher education institutions. We used particular methods as synthesis, analysis, induction and deduction, methods of comparison and abstraction. The conclusions state that during the study students get acquainted with the basics of information competence during theoretical courses, but work with its use is based on practical use. An analysis of the curricula of several European universities has shown that the integration of this element into the educational process is linked to practice.
