IMPACT OF THE COVID-19 PANDEMIC ON FINANCIAL RESULTS OF CONSULTING WORLDWIDE
Authors: Tiazhkorob Iryna , Markanych Tetiana
Published: April 2022

Purpose. The aim of the article is to determine the tendency to change the financial results of consulting activities in the world in the context of the COVID-19 pandemic.

Methodology of research. The following general scientific research methods are used to achieve this goal, in particular: comparison – to compare the financial results of consulting activities depending on the field of activity of economic entities, between regions and countries of the world; absolute and relative values – in the analysis of revenues of leading consulting companies; tabular and graphical – to visualize the dynamics and structure of the analysed indicators; generalizations – to justify the conclusions.

Findings. It is determined that the COVID-19 pandemic had a negative impact on the development of the consulting market in 2019-2020, which led to a reduction in its size. It was found that there are regional and sectoral differences in the loss of income of consulting companies around the world. It is concluded that the impact of the unfavourable economic situation on the financial results of the four leading consulting companies was insignificant relative to the level of the global consulting market. It is established that new models of consulting cooperation are remote (virtual) and hybrid models of work. It is stated that for the effective implementation of innovative technologies it is necessary to have a physical workplace for the company’s staff.

The expediency of implementing a strategy of narrow specialization by consulting companies to avoid or limit the risk of lower prices and loss of income from consulting activities is substantiated. It is argued that there is a demand for professional consulting services from economic entities, due to the need to overcome the financial and economic consequences of the pandemic and adapt to new economic conditions.

Originality. Characteristics of trends in the development of consulting activities in the world were further developed.

Practical value. Determining global trends in the financial results of global consulting companies will serve as a basis for the formation of adaptive mechanisms of consulting activities in Ukraine.

Key words: consulting market; consulting activity; consulting companies; income; pandemic COVID-19.

Published: April 2022

Introduction: Fingerprints and Lip prints has its reliability for its uniqueness and can be used solelyas an aid in identification for civil and criminal cases. Hence a correlation between the fingerprints andlip prints can bring up a new approach or idea in the field of Forensic Medicine for solving medicolegalcases. The present study was conducted on 25 pairs of twins with the main objective to find any existingcorrelation between fingerprints and lip prints and to determine the most predominant finger print andlip print pattern among Twin A and Twin B individually.Materials and Methods: The study was done is subjects age ranging from 6-18 years. A proforma withsubject particulars and consent form was prepared. Lip prints were obtained in a drawing chart, themiddle part of the lower lip was analysed based on Suzuki and Tsuchihashi classification. Fingerprint ofleft thumb finger was obtained in a white paper and analysed based on Henry’s system of classification.Results: The present study showed that there was no significant correlation between the Lip prints andFingerprints in Twins with p value >0.001. Among twin A and twin B the most predominant Lip printpattern was Type I’ and the Fingerprint pattern was Loop pattern respectively.Conclusion: Lip prints and Fingerprints are two important parameters for an individual in identification.There are various studies till now in individuals but very few in twins. So, in this study we made anattempt to find the correlation between the parameters, whether they were existing or not and found thatthere was no significant correlation yet can be used as a separate tool. Hence it is essential to performfurther studies on a larger group and create a database for getting accurate results.

Hospital is health service institution that provides complete individual health services that provideinpatient, outpatient, and emergency services. In operatingservices the hospital is required to havepermit. Permit is granted if it meets the requirements and standards to ensure the safety of patients,hospitals and health workers. The quality of hospital services is tested through the accreditationprocess,it could not be done during pandemic. Therefore, many policies have been issued, includingthe Circular of Health Minister No. HK.02.01/MENKES/455/2020 Year 2020. This circular facilitatesthe permitextension but does not givedetail abouthow to maintain the hospitalquality and services.During pandemic, the surge in Covid patients is not comparable to the hospitalscapabilities that aredifferent such as in the human resources and the facilities and infrastructure. Many hospitals are fullbecause they have to treat Corona Virus Disease 2019 patients, a lot of equipment, rooms and bedsmust be added, but the health workers that workare limited so that health workers have to work extra toserve patients that increase every day. This situation can cause physical and mental fatigue which overtime has impact on health services so that negligence can occur. So hospitals need to make protectionstandards for health workers in addition to legal responsibility for losses caused by health workersaccording to article 46 of the Hospital Law.

Interleukin 2 and interleukin 6 are the main cytokines involved in host immune response to H.pylori infection. The aim of the present study are to assess the serum level of IL-6 and IL–2 in H.pylori infected patients and to study their association with gastric endoscopy findings. Methods: One hundred and seven suspected patients and 19 healthy were recruited. The confirmed positivity of H.pylori detection was based on a rapid urease test (R.U.T) and stool antigen test. Serum concentrations of IL-2 and IL-6 were measuring by ELISA. Results: Seventy-five (70%) patients were positive for H.pylori. Both interleukins were found at higher levels in patients than in healthy (p- value <0.05). Interestingly, the level of IL-2 was lower in patients infected with H.pylori (43.40 pg/ml) than those who were not infected (85.2 pg/ml), while the level of IL-6 was higher in patients infected with H.pylori (117 pg/ml) than those not infected (40 pg/ml), p-value <0.05. Furthermore, the increasing levels of both interleukins were correlated with disease progress.

Published: April 2022

Present study aims to explore Pichia kudriavzevii FOL-04 (FOL-04)’s: i) survival against artificial gastric juice (AGJ) and artificial bile juice (ABJ), ii) growth kinetics in shake flask (SF) and fed-batch trials (FBT). Survival of FOL-04 as measured by relative cell density (RCD) against AGJ and ABJ was screened at four different pH-levels (control, 3, 2, 1.5) and ox-bile concentrations (control, 0.2%, 1%, 2%), respectively. Growth kinetics was calculated by periodic measurement of OD600 in SF (225 rpm, 30°C) or in FBT using exponential feeding regimen where pH, dissolved-oxygen and temperature were controlled at 5.5, 21%, and 30°C, respectively. The doubling-time, maximum specific growth rate, and final cell densities achieved for SF and FBT were 81.7min, 1.67, 11.79 and 170.4 min, 4.75, 37.95, respectively. RCDs calculated were similar for pH=3 and control vs both were significantly higher(p<0.05) than pH=1.5 and 2 with the latter two pH-levels were not significantly different(p>0.05). RCDs were similar across control, 0.2%, and 1% ox-bile levels(p>0.05). However, 2% ox-bile yielded significantly lower RCD (p<0.05) compared to all except 1%. FOL-04 is a potential probiotic candidate showing robustness against AGJ and ABJ and remarkable biomass increase was achieved when grown under FBT which could pave the way for developing a yeast-based probiotic using this strain.

Não há relacionamentos humanos sem conflitos. Para a psicanálise, essa premissa é primordial nos estudos do vínculo amoroso que o sujeito faz com o outro. Este trabalho tem o objetivo de realizar certa aproximação bibliográfica com os temas da ambivalência e conjugalidade. Articulando esses dois temas e seguindo as direções freudianas e pós-freudianas no que compete à literatura psicanalítica, onde serão discutidos o jogo complexo das identificações projetivas e os modos de subjetivações na conjugalidade. Conclui-se que a relação na conjugalidade já é precedida no sujeito por inerentes ambivalências e conflitos com suas próprias pulsões insatisfeitas em relação a suas escolhas objetais. Observou-se no Brasil o agravamento desses fatores sendo intensificado no isolamento social por conta da pandemia da COVID-19.

Published: April 2022

Purpose – The main goal is to compare and contrast the expectations of millennials, which skills will be needed for business in contrast to the entrepreneurial experience of the focus group of eight successful entrepreneurs from each country.
Research methodology – A cross-national case study is made, based on two focus groups per country (80 business students and eight entrepreneurs from the Czech Republic and Romania), qualitative research findings are presented.
Findings – Two competency models were evaluated, when the Romanian model is mostly motivation-oriented and the Czech model is performance-oriented.
Research limitations – Future studies should use an extended research sample and compare various methods for teaching entrepreneurship to students from different study areas and compare the impact of education on their mind-set before and after business courses finish.
Practical implications – The development of competency models in cooperation with experienced entrepreneurs would have the potential to increase students’ willingness to start up and prepare tailored business education. Possibility to create own generic models.
Originality/Value – The originality could be seen in comparison of two focus groups – students and entrepreneurs – which have not been done before from a conflict comparison point of view.
Revisiting BD-06 1339b: A Likely False Positive Caused by Stellar Activity
Authors: Simpson Emilie R. , Fetherolf Tara , Kane Stephen R. , Li Zhexing , Pepper Joshua , Močnik Teo
Published: April 2022

As long as astronomers have searched for exoplanets, the intrinsic variability of host stars has interfered with the ability to reliably detect and confirm exoplanets. One particular source of false positives is the presence of stellar magnetic or chromospheric activity that can mimic the radial velocity reflex motion of a planet. Here we present the results of a photometric data analysis for the known planet-hosting star BD –06°1339, observed by the Transiting Exoplanet Survey Satellite during Sector 6 at a cadence of 2 minutes. We discuss evidence that suggests that the observed 3.9-day periodic radial velocity signature may be caused by stellar activity rather than a planetary companion, since variability detected in the photometric data is consistent with the periodic signal. We conclude that the previously reported planetary signature is likely the result of a false-positive signal resulting from stellar activity, and we discuss the need for more data to confirm this conclusion.
A Systematic Study about Orbit Flips of Test Particles Caused by Eccentric Von Zeipel–Lidov–Kozai Effects
Authors: Lei Hanlun
Published: April 2022

The problem of orbit flips caused by eccentric von Zeipel–Lidov–Kozai effects is systematically investigated by means of three approaches, including Poincaré sections, dynamical system theory (periodic orbits and invariant manifolds), and perturbation treatments. Poincaré sections show that orbit flips are due to the existence of islands of libration centered at inclination of 90°, dynamical system theory shows that orbit flips are due to the existence of polar periodic orbits and invariant manifolds, and perturbative treatments indicate that orbit flips are due to the libration of a certain critical argument. Using these approaches, the boundaries of flipping regions in the entire parameter space are produced, and they are in excellent agreement with one another. Through analysis, the essence of flipping orbits is reached: (a) flipping orbits are a kind of quasiperiodic trajectory around polar periodic orbits and invariant manifolds at the same level of Hamiltonian provide boundaries of flipping regions, and (b) flipping orbits are a kind of resonant trajectory, and resonant width measures the size of flipping regions.

Published: April 2022

The physical properties responsible for the formation and evolution of the corona and heliosphere are still not completely understood. 3D MHD global modeling is a powerful tool to investigate all the possible candidate processes. To fully understand the role of each of them, we need a validation process where the output from the simulations is quantitatively compared to the observational data. In this work, we present the results from our validation process applied to the wave turbulence driven 3D MHD corona-wind model WindPredict-AW. At this stage of the model development, we focus the work to the coronal regime in quiescent condition. We analyze three simulation results, which differ by the boundary values. We use the 3D distributions of density and temperature, output from the simulations at the time of around the first Parker Solar Probe perihelion (during minimum of the solar activity), to synthesize both extreme ultraviolet (EUV) and white-light-polarized (WL pB) images to reproduce the observed solar corona. For these tests, we selected AIA 193 Å, 211 Å, and 171 Å EUV emissions, MLSO K-Cor, and LASCO C2 pB images obtained on 2018 November 6 and 7. We then make quantitative comparisons of the disk and off limb corona. We show that our model is able to produce synthetic images comparable to those of the observed corona.

These results enable inferences about binary object populations via direct modeling of object position and pair separation data, without resorting to standard estimators of the two-point correlation function. Analyzing mock data sets designed to mimic known dwarf spheroidal galaxies, we demonstrate the ability to recover input properties including the number of wide binary star systems and, in cases where the number of resolved binary pairs is assumed to be ≳a few hundred, characteristic features (e.g., steepening and/or truncation) of their separation function. Combined with forthcoming observational capabilities, this methodology opens a window onto the formation and/or survival of wide binary populations in dwarf galaxies, and offers a novel probe of inferred dark matter substructure on the smallest galactic scales.

We present ultraviolet spectroscopy covering the Lyα + N v complex of six candidate low-redshift (0.9 < z < 1.5) weak emission-line quasars (WLQs) based on observations with the Hubble Space Telescope. The original systematic searches for these puzzling Type 1 quasars with intrinsically weak broad emission lines revealed an N ≈ 100 WLQ population from optical spectroscopy of high-redshift (z > 3) quasars, defined by a Lyα + N v rest-frame equivalent width (EW) threshold <15.4 Å. Identification of lower-redshift (z < 3) WLQ candidates, however, has relied primarily on optical spectroscopy of weak broad emission lines at longer rest-frame wavelengths. With these new observations expanding existing optical coverage into the ultraviolet, we explore unifying the low- and high-z WLQ populations via EW[Lyα+N v]. Two objects in the sample unify with high-z WLQs, three others appear consistent with the intermediate portion of the population connecting WLQs and normal quasars, and the final object is consistent with typical quasars. The expanded wavelength coverage improves the number of available line diagnostics for our individual targets, allowing a better understanding of the shapes of their ionizing continua. The ratio of EW[Lyα+N v] to EW[Mg ii] in our sample is generally small but varied, favoring a soft ionizing continuum scenario for WLQs, and we find a lack of correlation between EW[Lyα+N v] and the X-ray properties of our targets, consistent with a “slim-disk” shielding gas model. We also find indications that weak absorption may be a more significant contaminant in low-z WLQ populations than previously thought.
The Ca ii H and K Rotation–Activity Relation in 53 Mid-to-late-type M Dwarfs
Authors: Boudreaux Thomas M. , Newton Elisabeth R. , Mondrik Nicholas , Charbonneau David , Irwin Jonathan
Published: April 2022

In the canonical theory of stellar magnetic dynamo, the tachocline in partially convective stars serves to arrange small-scale fields, generated by stochastic movement of plasma into a coherent large-scale field. Mid-to-late-type M dwarfs, which are fully convective, show more magnetic activity than classical magnetic dynamo theory predicts. However, mid-to-late-type M dwarfs show tight correlations between rotation and magnetic activity, consistent with elements of classical dynamo theory. We use data from the Magellan Inamori Kyocera Echelle Spectrograph to detail the relation between Ca ii H and K flux and rotation period for these low-mass stars. We measure

In particular, the σ–δ mixing reduces the neutron star radius; thus, the present calculation can simultaneously reproduce the dimensionless tidal deformabilities of a canonical 1.4 M

Revisiting Black Hole Hyperaccretion in the Center of Gamma-Ray Bursts for the Lower Mass Gap
Authors: Qu Hui-Min , Liu Tong
Published: April 2022

The ultrarelativistic jets triggered by neutrino annihilation processes or Blandford–Znajek (BZ) mechanisms in stellar-mass black hole (BH) hyperaccretion systems are generally considered to power gamma-ray bursts (GRBs). Due to the high accretion rate, the central BHs might grow rapidly on a short timescale, providing a new way to understand the lower mass gap problem. In this paper, we use the BH hyperaccretion model to investigate BH mass growth based on observational GRB data. The results show that (i) if the initial BH mass is set as 3 M
⊙, the neutrino annihilation processes are capable of fueling the BHs to escape the lower mass gap for more than half of long-duration GRBs (LGRBs), while the BZ mechanism is inefficient in triggering BH growth for LGRBs; (ii) the mean BH mass growth in the case of LGRBs without observable supernova (SN) association is much larger than that in the case of LGRBs associated with SNe for both mechanisms, which implies that more massive progenitors or lower SN explosion energies prevail throughout the former cases; (iii) for the short-duration GRBs, the mean BH mass growth is satisfied with the mass supply limitation in the scenario of compact object mergers, but the hyperaccretion processes are unable to rescue BHs from the gap in binary neutron star (NS) mergers or the initial BH mass being 3 M

A provisional checklist of European butterfly larval foodplants
Authors: Clarke Harry E.
Published: April 2022

Successful conservation of butterflies is dependent on knowing which larval foodplants they use. However, many published lists of larval foodplants have been copied from previous lists, which in turn have been copied from previous lists. Consequently, errors have crept in, and many plant names have long been superseded. This can result in duplicates in the list, with the same plant being given two different names. Most plant lists do not include the authority, which can make it difficult or impossible to identify which plant is being referred to. For the first time, a list of the current accepted plant names utilised by 471 European butterfly larvae is presented, with references. Where possible, errors in previous lists have been removed. The list of larval foodplants doubled from previous published lists. This has resulted in a list of 1506 different plant species in 72 different families. 86 plant records are only known at the generic level. Larval foodplants of 25 butterfly species are currently unknown. Whilst most plant families are utilised by less than six butterfly species, a few plant families are particularly favoured, with the Poaceae and Fabaceae being the most popular. Similarly, most plant species are only utilised by a few butterfly species, butFestuca ovinaandFestuca rubraare favoured by a large number of butterfly species. 20% of European butterfly larvae are monophagous, 50% are oligophagous, and 30% are polyphagous, withCelastrina argiolusable to use plants in 19 different families.

Moringa oleifera is a tropical plant in the Moringaceae family that contains a lot of bioactive compounds. This study aimed to isolate and characterize the enzyme xanthine oxidase (XO), and conducted inhibitory tests on XO using methanol extracts of M. oleifera leaves. The xanthine oxidase enzyme isolated from bovine milk was characterized to determine the optimum pH, temperature, and substrate concentration. XO inhibition was evaluated by in vitro and in silico methods. The results of XO isolation and characterization of bovine milk showed the optimum conditions at pH 6.5, substrate concentration of 0.1 mM, and temperature 35 °C with an activity rate of 32.47 mU/mL; 21.55 mU/mL, and 21.94 mU/mL. Inhibition analysis results on methanol extract of M. oleifera leaves showed the highest activity decrease at the extract concentration of 160 ppm, with a relative inhibition value of 21.35%, while allopurinol as a positive control has a relative value inhibition of 61.21%. Relative value inhibition indicated the potential of M. oleifera leaves as a source of medicinal plants for gout sufferers. Additionally, a computational analysis was performed to observe the molecular interaction between the primary compounds of M. oleifera leaves, i.e., 5-O-acetyl-thio-octyl-β-L-rhamnofuranoside, quinic acid, and 2-dimethyl(trimethylsilylmethyl)silyloxymethyltetrahydrofuran, and XO using the molecular docking method. The finding implied that these compounds are bound to the catalytic sites of XO by hydrogen bonds and hydrophobic interactions, indicating the primary compounds of M. oleifera leaves could become XO inhibitors to treat gout disease.
Morphology and distribution of the Middle Asian centipede genus Krateraspis Lignau, 1929 (Chilopoda, Geophilomorpha, Mecistocephalidae)
Authors: Dyachkov Yurii V. , Bonato Lucio
Published: April 2022

A comprehensive redescription of the poorly known mecistocephalid genus Krateraspis Lignau, 1929 and its two species is provided, based on the examination of type material and new specimens, as well as the critical evaluation of all published information. Krateraspis is confirmed differing from all other Mecistocephalidae especially for a peculiar pattern of areolation and setation of the clypeus. Records from 24 localities indicate that Krateraspis is limited to a narrow area of Middle Asia, from the Western Tian-Shan to the western offshoots of Pamir Mountains. Two species are morphologically distinguishable: K. meinerti (Sseliwanoff, 1881) and K. sselivanovi Titova, 1975. They differ mainly in details of the clypeus and maxillae, in the pattern of forcipular denticles, and in the number of legs. Tygarrup asiaticus Verhoeff, 1930 is confirmed as a junior synonym of K. meinerti, and a lectotype is designated for the former.
Las Vegas et Macao : villes miroir ou diversité des capitalismes urbains ?
Authors: Grondeau Alexandre , Lebeau Boris
Published: April 2022

Villes emblématiques des jeux, Las Vegas et Macao, connaissent depuis une quinzaine d’années un destin convergent résultant de l’internationalisation des opérateurs de casinos et semblant avoir abouti à la création d’un modèle « générique » de ville-casinos. Le mimétisme des formes de la ville ne saurait pourtant occulter la singularité des modèles de croissance ayant cours de part et d’autre du Pacifique, non plus que leur dimension concurrentielle. Cet article qui propose un décryptage minutieux des ressorts de la croissance dans les deux villes, met en évidence l’existence de capitalismes urbains individualisés et invite à une lecture nuancée et actualisée des effets de la mondialisation.
