On the Possibility of Generalized Wormhole Formation in the Galactic Halo Due to Dark Matter Using the Observational Data within the Matter Coupling Gravity Formalism
Authors: Mustafa G. , Maurya S. K. , Ray Saibal 
Published: December 2022

Abstract
In this article, we find the possibility of generalized wormhole formation in the galactic halo due to dark matter using observational data within the matter coupling gravity formalism. Keeping this as a target, we specifically employ f(R, T) gravity with (i) a variational approach concerning the metric, and (ii) the anisotropic source of matter. To understand the features of the wormholes, we thoroughly calculated and analyzed the energy conditions under f(R, T) gravity. We discuss the second embedded wormhole solution, known as the generalized Ellis–Bronnikov spacetime (ultrastatic wormhole model), in terms of the tortoise coordinate. Thereafter we generate and compare different wormhole solutions depending on the parametric values. In the second part of our investigation, we presented dark matter halos and provided interesting features by considering a couple of profiles. For the dark matter halos models, we particularly use the observational data of the M87 galaxy and the Milky Way galaxy.

Published: December 2022

Abstract
Prestellar cores, the birthplace of Sun-like stars, form from the fragmentation of the filamentary structure that composes molecular clouds, from which they must inherit at least partially the kinematics. Furthermore, when they are on the verge of gravitational collapse, they show signs of subsonic infall motions. How extended these motions are, which depends on how the collapse occurs, remains largely unknown. We want to investigate the kinematics of the envelope that surrounds the prototypical prestellar core L1544, studying the cloud-core connection. To our aims, we observed the HCO+ (1–0) transition in a large map. HCO+ is expected to be abundant in the envelope, making it an ideal probe of the large-scale kinematics in the source. We modeled the spectrum at the dust peak by means of a nonlocal thermodynamical equilibrium radiative transfer. In order to reproduce the spectrum at the dust peak, a large (∼1 pc) envelope is needed, with low density (tens of cm−3 at most) and contraction motions, with an inward velocity of ≈ 0.05 km s−1. We fitted the data cube using the Hill5 model, which implements a simple model for the optical depth and excitation temperature profiles along the line of sight, in order to obtain a map of the infall velocity. This shows that the infall motions are extended, with typical values in the range 0.1–0.2 km s−1. Our results suggest that the contraction motions extend in the diffuse envelope surrounding the core, which is consistent with recent magnetic field measurements in the source, which showed that the envelope is magnetically supercritical.

The primordial He abundance Y

λ10830 near-infrared (NIR) emission. Here we present deep Subaru NIR spectroscopy for 10 EMPGs. Combining the existing optical data, He/H values of 5 out of the 10 EMPGs are reliably derived by the Markov chain Monte Carlo algorithm. Adding the existing 3 EMPGs and 51 moderately metal-poor (0.1–0.4Z

Black Hole Images as Tests of General Relativity: Effects of Plasma Physics
Authors: Özel Feryal , Psaltis Dimitrios , Younsi Ziri 
Published: December 2022

Abstract
The horizon-scale images of black holes obtained with the Event Horizon Telescope have provided new probes of their metrics and tests of general relativity. The images are characterized by a bright, near-circular ring from the gravitationally lensed emission from the hot plasma and a deep central depression cast by the black hole. The metric tests rely on the fact that the bright ring closely traces the boundary of the black hole shadow with a small displacement that has been quantified using simulations. In this paper we develop a self-consistent covariant analytic model of the accretion flow that spans a broad range of plasma conditions and black hole properties to explore the general validity of this result. We show that, for any physical model of the accretion flow, the ring always encompasses the outline of the shadow and is not displaced by it by more than half the ring width. This result is a consequence of conservation laws and basic thermodynamic considerations and does not depend on the microphysics of the plasma or the details of the numerical simulations. We also present a quantitative measurement of the bias between the bright ring and the shadow radius based on the analytical models.
Searching for Extremely Blue UV Continuum Slopes at z = 7–11 in JWST/NIRCam Imaging: Implications for Stellar Metallicity and Ionizing Photon Escape in Early Galaxies

Abstract
The ultraviolet (UV) continuum slope (β, where f

λ
∝ λ

β
) of galaxies is sensitive to a variety of properties, from the metallicity and age of the stellar population to dust attenuation throughout the galaxy. Considerable attention has focused on identifying reionization-era galaxies with very blue UV slopes (β < −3). Not only do such systems provide a signpost of low-metallicity stars, but they also identify galaxies likely to leak ionizing photons from their H ii regions as such blue UV slopes require the reddening effect of nebular continuum to be diminished. In this paper we present a search for reionization-era galaxies with very blue UV colors in recent JWST/NIRCam imaging of the Extended Groth Strip field. We characterize UV slopes for a large sample of z ≃ 7–11 galaxies, finding a median of β = −2.0. Two lower luminosity (M
UV ≃ −19.5) and lower stellar mass (6–10 × 107
M
⊙) systems exhibit extremely blue UV slopes (β = −2.9 to −3.1) and rest-optical photometry indicating weak nebular line emission. Each system is very compact (r

e
≲ 260 pc) with very high star formation-rate surface densities. We model the spectral energy distributions (SEDs) with a suite of BEAGLE models with varying levels of ionizing photon escape. The SEDs cannot be reproduced with our fiducial (f
esc,H II
= 0) or alpha-enhanced (Z
⋆ < Z
ISM) models. The combined blue UV slopes and weak nebular emission are best-fit by models with significant ionizing photon escape from H ii regions (f
esc,H II
= 0.5–0.8) and extremely low-metallicity massive stars (Z
⋆ = 0.01–0.06 Z
⊙). The discovery of these galaxies highlights the potential for JWST to identify large numbers of candidate Lyman continuum leaking galaxies in the reionization era and suggests low-metallicity stellar populations may be common in dwarf galaxies at z > 7.
Using the EPM method for the estimation of soil erosion in forest territories in the upper part of Dzherman River
Authors: Pavlova-Traykova Eli 
Published: December 2022

One of the most vulnerable to soil erosion parts in Bulgaria is the Struma river watershed. In the past, a lot of erosion control activities have been carried out in this catchment, but the topographic condition and easily prone to soil erosion soils are still redounding to erosion processes.&nbsp;
As a global problem with severe effects on the environment, soil erosion is on the agenda of scientific community. Because of difficult recognition on time, various methods for erosion risk and sediment loss assessment were applied. For mountainous watersheds one of the most appropriate approach is Erosion Potential Model (EPM).&nbsp;
The study aims to evaluate soil erosion and investigate its spatial distribution by applying EPM, also known as Gavrilovic method. The object of investigation is the upper part of the Dzherman river, which is tributary of Struma river. The method was implemented only for forest territories to determine the most vulnerable part of the forest. The results showed that for the forest territories the average value of the coefficient Z is 0.19, which defines erosion as &ldquo;low&rdquo; and the average soil loss only for forest areas is 15.28 m3/km2/year. Nevertheless there are territories with more than 100 m3/km2/year.&nbsp;

Authors: Madzhov Svetozar 
Published: December 2022

In the present study the main numerical characteristics of the reliability indicators for the Komatsu SAA4D104E-1 engines of the KOMATSU WB93R-5 backhoe loader have been determined, and the laws of resource allocation have been established.
To study the level of reliability of machines, a methodology for experimental research has been developed, where the complex, comparative and formal methods, as well as the systematic, cybernetic and statistical approach have been used. It has been found that increasing the level of reliability of the engine elements can be improved by increasing the quality and timeliness of the repair and maintenance activities and compliance with the rules of operation.
This study is a continuation of a study conducted by the author.

Published: December 2022

Aims: Landscapes of Middle Asia are exposed to human influence due to long-lasting pastoral tradition, and now are largely dominated by non-forest vegetation. Graminoids perform key ecosystem functions, and constitute an important feed source for livestock. We studied the distribution patterns of graminoids cover under climatic and grazing pressure gradients in different open vegetation types. Study area: Tajikistan, Kyrgyzstan. Methods: 1,525 vegetation plots representing five open vegetation types (mires, salt marshes, tall-forb communities, pseudosteppes and steppes) were extracted from the Vegetation of Middle Asia Database. We assessed the relative cover of graminoid species in each vegetation type. The importance of mean annual temperature, sum of annual precipitation, aridity and livestock density as drivers of relative cover of graminoids contribution patterns in the five vegetation types were explored with use of polynomial functions and commonality analysis. Results: Open ecosystems of Middle Asia are characterized by different graminoid contributions. The highest relative cover of graminoids was found for steppes, pseudosteppes and mires. Comparison of model fits for relationship between the graminoids cover, climatic parameters and livestock pressure indicated advantage of polynomial models. The best-fitting models for pseudosteppes were for mean annual temperature, Aridity Index and livestock density, for steppes mean annual temperature and Aridity Index, and for salt marshes mean annual temperature. For mires and tall-forb communities, the models showed a poor fit or no effect of the variables studied. Conclusions: Our study shows that climate and livestock pressure have an impact on the contribution of graminoids in open vegetation types, but a general pattern is difficult to describe. Ongoing climate change may influence the share of graminoids in salt marshes, steppes and pseudosteppes. Grazing (with a common effect of climatic factors) is the most important factor influencing graminoids contribution on pseudosteppes, confirming the secondary origin of this vegetation type.
Taxonomic reference: The nomenclature of the vascular plants follows Plants of the World Online (POWO 2022) and problematic taxonomic issues were based on The World Flora Online (WFO 2022). Nomenclature of Stipa spp. follows Nobis et al. (2020).
Circulation et appropriation d’idées : l’utilisation de Carl Schmitt par Miguel Reale dans la légitimation du coup d’État civil-militaire de 1964
Authors: Cunha Diogo , Gasparetto Antonio 
Published: December 2022

Cet article a pour objectif d’analyser l’usage
fait par Miguel Reale de la pensée de Carl Schmitt en vue de légitimer
juridiquement le coup d’État civil-militaire au Brésil en 1964. Nous
soutenons que la pensée politique de Reale a évolué du corporatisme
fasciste pendant sa jeunesse, vers une pensée toujours autoritaire,
mais dorénavant épurée de ses références fascistes et désormais fondée
sur un outillage conceptuel philosophique et juridique sophistiqué,
dans lequel les concepts schmittiens occupent une place centrale. Pour
examiner l’usage de Schmitt par Reale, nous nous pencherons sur
l’œuvre de l’un et de l’autre : du premier, Théologie politique (1922), La notion de politique (1927)
et Le gardien de la
Constitution (1928) ; du second, ses mémoires Destinos Cruzados et A Balança e a Espada (1987) et Imperativos da revolução de
março (1964). Cet article est divisé en trois parties. Dans la
première, nous examinons quelques présupposés théoriques et
méthodologiques sur lesquels nous nous sommes appuyés pour mener à
bien nos analyses ; dans la seconde, nous nous concentrons sur les
travaux de Carl Schmitt, mettant en exergue les principaux concepts
que Miguel Reale s’est appropriés ; dans la troisième, enfin, nous
analysons comment Reale les a opérationnalisés pour expliquer et,
surtout, légitimer la prise de pouvoir militaire en 1964.
Sustainable Business Model Innovation: From Value Uncaptured to Value Opportunities
Authors: Gennari Francesca 
Published: December 2022

COVID-19 pandemic crisis threatened the stability of economy and the survival of many firms, but it has been also the chance to challenge the current economic development path and to rethink firms’ business models according to a more sustainable approach. Academic literature states that business model (BM) innovation is a driver for the transition to sustainability. Sustainable business models (SBMs) incorporate sustainability vision in the main components of business model, which are value proposition, value creation and value capturing. Nevertheless, the usual approach to business models, based on a positive concept of value, can underestimate some areas of potential opportunities to catch. For this reason, in this paper we suggest to adopt a novelty approach that emphasizes the negative concept of value (value uncaptured) to identify unexploited value opportunities. This approach can help firms innovating their BMs towards SBMs.

Published: December 2022

Objectives:In this study, we aimed to compare the efficacy of ultrasonography (US) and steroid phonophoresis (PH) treatments in patients with idiopathic carpal tunnel syndrome (CTS).Patients and methods:Between January 2013 and May 2015, a total of 46 hands of 27 patients (5 males, 22 females; mean age: 47.3+13.7 years; range, 23 to 67 years) with idiopathic mild/moderate CTS without tenor atrophy or spontaneous activity in abductor pollicis brevis were included. The patients were randomly divided into three groups. The first group was ultrasound (US) group, the second group was PH group, and the third group was placebo US group. Continuous US with a frequency of 1 MHz, an intensity of 1.0 W/cm2was used in the US and the PH groups. The PH group received 0.1% dexamethasone. Placebo group received a frequency of 0 MHz, an intensity of 0 W/cm2US. Treatments were administered for five days a week, a total of 10 sessions. All patients also wore night splints during treatment. The Visual Analog Scale (VAS), Boston Carpal Tunnel Questionnaire consisting of two parts, namely the Symptom Severity Scale and Functional Status Scale), grip strength, and electroneurophysiological evaluations were compared before the treatment, after the treatment, and three months later.Results:All clinical parameters improved in all groups after treatment and at three months, except for the grip strength. Recovery in the sensory nerve conduction velocity between palm and wrist was seen in US group at three months after the treatment; however, recovery in the sensory nerve distal latency between the second finger and palm was seen in PH and placebo groups after treatment and at three months after the treatment.Conclusion:The results of this study suggest that splinting therapy combined with steroid PH, placebo or continuous US is effective for both clinical and electroneurophysiological improvement; however, electroneurophysiological improvement is limited.
UMA ABORDAGEM PRÁTICA NA CONSTRUÇÃO DA FUNÇÃO HORÁRIA E GRÁFICOS DO M.R.U COMO ESTRATÉGIA FACILITADORA DO PROCESSO DE ENSINO E APRENDIZAGEM DE FÍSICA

Neste trabalho apresentamos atividades práticas de Cinemática para alunos da 1° série do ensino médio de uma escola pública do interior da Bahia. As atividades foram orientadas de forma online pelo professor e norteando-se para a execução das mesmas os protocolos de biossegurança. O foco foi primeiramente a determinação da velocidade média de um corpo que executasse um movimento retilíneo e uniforme (M.R.U), de forma que as grandezas utilizadas para execução das práticas fossem corriqueiras aos alunos. As medidas aferidas in loco pelos envolvidos (aluno e seu par) foram monitoradas via ligação por vídeo pelo professor e ainda tiveram de ser transformadas para as unidades do sistema internacional de unidades (SI), para que fossem padronizadas. Como resultado dessas atividades práticas de Cinemática, os alunos puderam calcular a velocidade média no trajeto de A até B do corpo , e ainda construir seus respectivos gráficos de movimento com posição (s) em função do tempo gasto (t). As atividades práticas apesar de simples se mostraram prazerosas para com os envolvidos e ajudou os alunos na compreensão de Cinemática, diminuindo a aversão para com a Física e foi uma forma de ser usada como ferramenta de estratégia didática na construção de competências procedimentais dos alunos. A compreensão do tempo de encontro entre dois móveis, bem como da função horária 1° grau no MRU, foram mais bem entendidas pelos discentes durante as aulas, uma vez que houve um ambiente favorável às discussões da situação-problema em estudo, já que muitas das perguntas formuladas durante a aula síncrona se originaram dos próprios alunos que realizaram a prática.
