Abstract- This study is to see the impact of entrepreneurship education provided through entrepreneurship courses on entrepreneurial intentions among students in Karawang-West Java. The research model was adopted from Theory Planned Behavior (TPB). The theory of planned behavior includes independent variables, namely attitudes, subjective norms, and behavioral control. While the dependent variable, entrepreneurial intention is used. Questionnaires were distributed via google form to students who have taken entrepreneurship courses, as many as 115 samples were obtained, and 100 samples that met the criteria were used for processing. Research analysis using SEM PLS found that subjective norms and behavioral control did not affect the intention to entrepreneurship, only attitude that had a significant effect on the intention to entrepreneurship in students. These results prove in the sample taken that the attitude of students more causes entrepreneurial intention, how they are interested in seeing business opportunities, have a positive view of things and always dare to take any risks that come. This finding is expected to change the education plan for entrepreneurship courses, which are expected to include elements to increase interest, think positively, and be optimistic to generate intentions to become an entrepreneur.

Authors: Rassetto María Josefa , Farina Julieta , Peréz Daniel 
Published: August 2021

Este trabajo presenta el tramo inicial de una tesis doctoral[1] que incluye el estudio de los antecedentes en investigación educativa sobre la germinación de semillas. Se expone una revisión de artículos publicados en revistas indizadas, considerando investigaciones realizadas en distintos niveles educativos. Se encontraron 25 artículos, que se estudiaron según las dimensiones analíticas: editorial, enseñanza de la germinación, procedencia biogeográfica de la planta, dormición de la semilla y tema del trabajo. Los resultados muestran que su enseñanza se basa principalmente en el uso de germinadores de semillas de Phaseolus vulgaris (porotos o frijoles), en la aplicación agrícola de semillas y en su mayoría no mencionan mecanismos de dormición o la forma de superarlos. Se concluye que el interés en los artículos analizados se centra en el proceso de emergencia de la plántula, dejando fuera las diferencias que se presentan en distintas especies, el origen biogeográfico, la relación de la germinación con las adaptaciones, los conocimientos socioculturales, o la posible aplicación a la restauración ecológica.

Authors: Da Silva Medeiros Willian , Brancher Vantoir Roberto , Frizon Auler Neiva Maria 
Published: August 2021

Esta pesquisa bibliográfica, de natureza teórica, foi realizada através de uma revisão de literatura das dissertações e teses publicadas na Biblioteca Digital Brasileira de Teses e Dissertações - BDTD, que teve por objetivo mapear o que tem sido pesquisado sobre os saberes produzidos e mobilizados por professores de Biologia enquanto elementos da formação desses profissionais. A partir dos critérios de busca e seleção foram encontradas 18 produções de interesse para esta investigação. Com o mapeamento e análise das dissertações e teses foi possível identificar uma grande diversidade de trabalhos, de abordagens e de propostas que emergiram deste cenário analisado. Identificamos que, em sua maioria, as produções contemplaram os processos de formação inicial de professores nas licenciaturas e espaços específicos. Salientamos a incipiência dos estudos voltados à formação do professor de Biologia para a Educação Profissional e Tecnológica[1], de modo que apenas uma produção abordou a formação do professor de Biologia neste contexto.

[1] Embora este trabalho esteja incluído em uma pesquisa do campo da Educação Profissional e Tecnológica intitulada “Trajetos formativos e saberes docentes: ressignificando a docência de biologia na Educação Profissional e Tecnológica”, destacamos que na ocasião das buscas não obtivemos resultados de produções com os descritores específicos para "Educação Profissional". A única produção que problematiza a docência de Biologia na EPT emergiu quando retiramos estes descritores específicos, situação que justifica a necessidade de pesquisas que abordem temáticas nesta especificidade da atuação docente.
Effects of poultry litter and inorganic fertilizer on growth and productivity of Rhizobia inoculated and non-inoculated beans
Authors: Olet Eunice , Mubiru David 
Published: August 2021

Agriculture has been the most contributing sector towards Uganda’s economy. However, its output has always been hampered by declining soil fertility leading to reduced yields, increased agricultural losses, and malnourishment among low-income earners. In Uganda, there is scanty research about the effectiveness of either organic or inorganic fertilizers in crop production. Therefore, there was a need to establish the effectiveness of inorganic fertilizer (N: P: K; 17:17:17) and organic fertilizer (poultry manure/litter) on the growth, and productivity of rhizobia inoculated and non-inoculated bio-fortified NAROBEAN 2 variety, which is rich in iron and zinc, high yielding and drought resistant. A randomized complete block design experiment was conducted at Mbarara Zonal Agricultural Research and Development Institute (MBAZARDI). Poultry litter was applied at the rate of (10t/ha), N: P: K 17:17:17 at 20.3 kg ha-1, and Rhizobia at 250g per 15 kg of beans. Treatments were; Rhizobia + N: P: K 17:17:17 (M 1), Rhizobia + Poultry litter (M 2), Rhizobia only (M 3), Poultry litter only (M 4), N: P: K 17:17:17 only (M 5) and the control (M 6). Growth parameters included the number of leaves, branches, and shoot height; and productivity parameters included the number of pods produced per plant and economic yield. Statistical analyses were done at 5% level of significance. The growth parameters showed no significant difference (P > 0.05) while the bean grain yield and productivity were significantly different (p < 0.05) under the various treatments. Rhizobia + Poultry litter and N: P: K 17:17:17 only, produced the highest effect on both growth and productivity as compared to other treatments. Application of rhizobia with poultry manure was the best soil treatment for increasing the growth and productivity of NAROBEAN 2. This will increase production, food security, abate malnutrition, and sustainably improve soil quality.

The last decade is characterized by a number of military conflicts, in most episodes of which the achievement of the goal (reconnaissance and (or) defeat of certain targets) by the warring parties is mostly achieved through the use of aircraft, including small and (or) unmanned. The main difference is to obtain the desired results without a direct collision with the enemy ground component of troops (forces).
Most of the recommended measures to combat aircraft in modern conditions can be reduced to: the rational construction of battle order (using the air defense separation), the widespread use of covert communications, radio reconnaissance and electronic warfare, the creation of erroneous and camouflage combat (reserve) positions of air defense means , automation of transmission and processing of information about the air situation with the use of modern technologies and increase the accuracy of coordinate information provided to combat (or fire) means.
Improving the accuracy of coordinate information causes: the possibility of searchless detection and (or) capture of air targets by fire, increasing the survivability of air defense systems by reducing working hours (including time for "radiation") and rapid change of their positions after the task. Modern algorithms for processing coordinate information provided by air defense systems take into account the errors of measurement of primary coordinates by radio engineering, the delay time of information in communication channels and its possible distortion. At the same time, they do not explicitly take into account the influence of topographic errors and orientation errors of radio equipment.
In the work, with the use of methods of mathematical statistics and mathematical modeling, the analysis of influence of topographic errors and orientation of radio-technical means of airspace control on estimations of the coordinate information issued by them is carried out. The obtained ratios allow to make an appropriate assessment and provide recommendations for further research.

The Relationship Between Group Cohesion and Team Achievement: The Case of University Handball 2. League Teams
Authors: ÖZDEMİR İlknur , SEVİLMİŞ Ali 
Published: August 2021

The purpose of the study is to evaluate the success ranking of competitive handball teams at the same league level (2nd league) according to the group cohesion level and to determine the relationship between success ranking and group cohesion. Group cohesion was determined according to the Team Environment Questinnaire (GEQ), which was developed by Carron et al. (1985), and adapted to Turkish athletes by Unutmaz et al. (2011). As a result of the research, task cohesion levels of the teams that came first in the competition and the other teams are similar. The task cohesion level of men's teams is higher than women's teams. In addition, the relationship between social cohesion and team success, and between task cohesion and gender were analyzed.
As a result, it has been concluded that although task cohesion is necessary, it is not enough to achieve top positions, high social cohesion in the teams in the lowest league may cause failure and men exhibit more task cohesion than women in order to win.
The Infrared Echo of SN2010jl and Its Implications for Shock Breakout Characteristics
Authors: Dwek Eli , Sarangi Arkaprabha , Arendt Richard G. , Kallman Timothy , Kazanas Demos , Fox Ori D. 
Published: August 2021

Abstract
SN 2010jl is a Type IIn core-collapse supernova whose radiative output is powered by the interaction of the supernova (SN) shock wave with its surrounding dense circumstellar medium (CSM). After day ∼60, its light curve developed a near-infrared (NIR) excess emission from dust. This excess could be a thermal IR echo from preexisting CSM dust, or emission from newly formed dust either in the cooling post-shock region of the CSM, or in the cooling SN ejecta. Recent analysis has shown that dust formation in the CSM can commence only after day ∼380, and has also ruled out newly formed ejecta dust as the source of the NIR emission. The early (<380 days) NIR emission can therefore only be attributed to an IR echo. The H–K color temperature of the echo is about 1250 K. The best-fitting model requires the presence of about 1.6 × 10−4
M
⊙ of amorphous carbon dust at a distance of 2.2 × 1016 cm from the explosion. The CSM-powered luminosity is preceded by an intense burst of hard radiation generated by the breakout of the SN shock through the stellar surface. The peak burst luminosity seen by the CSM dust is significantly reduced by Thomson scattering in the CSM, but still has the potential of evaporating the dust needed to produce the echo. We show that the survival of the echo-producing dust provides important constraints on the intensity, effective temperature, and duration of the burst.
Generic Models for Disk-resolved and Disk-integrated Phase-dependent Linear Polarization of Light Reflected from Exoplanets
Authors: Chakrabarty Aritra , Sengupta Sujan 
Published: August 2021

Abstract
Similar to the case of solar system planets, reflected starlight from exoplanets is expected to be polarized due to atmospheric scattering, and the net disk-integrated polarization should be nonzero owing to the asymmetrical illumination of the planetary disk. The computation of the disk-integrated reflected flux and its state of polarization involves techniques for the calculation of the local reflection matrices, as well as the numerical recipes for integration over the planetary disks. In this paper, we present a novel approach to calculate the azimuth-dependent reflected intensity vectors at each location on the planetary disk divided into grids. We achieve this by solving the vector radiative transfer equations that describe linear polarization. Our calculations incorporate self-consistent atmospheric models of exoplanets over a wide range of equilibrium temperature, surface gravity, atmospheric composition, and cloud structure. A comparison of the flux and the amount of polarization calculated by considering both single and multiple scattering exhibits the effect of depolarization due to multiple scattering of light depending on the scattering albedo of the atmosphere. We have benchmarked our basic calculations against some of the existing models. We have also presented our models for the hot Jupiter HD 189733 b, indicating the level of precision required by future observations to detect the polarization of this planet in the optical and near-infrared wavelength region. The generic nature and the accuracy offered by our models make them an effective tool for modeling future observations of the polarized light reflected from exoplanets.
Magnetic Twists of Solar Filaments
Authors: Guo J. H. , Ni Y. W. , Qiu Y. , Zhong Z. , Guo Y. , Chen P. F. 
Published: August 2021

Abstract
Solar filaments are cold and dense materials situated in magnetic dips, which show distinct radiation characteristics compared to the surrounding coronal plasma. They are associated with coronal sheared and twisted magnetic field lines. However, the exact magnetic configuration supporting a filament material is not easy to ascertain because of the absence of routine observations of the magnetic field inside filaments. Since many filaments lie above weak-field regions, it is nearly impossible to extrapolate their coronal magnetic structures by applying the traditional methods to noisy photospheric magnetograms, in particular the horizontal components. In this paper, we construct magnetic structures for some filaments with the regularized Biot–Savart laws and calculate their magnetic twists. Moreover, we make a parameter survey for the flux ropes of the Titov–Démoulin-modified model to explore the factors affecting the twist of a force-free magnetic flux rope. It is found that the twist of a force-free flux rope,

, is proportional to its ratio of axial length to minor radius, L/a, and is basically independent of the overlying background magnetic field strength. Thus, we infer that long quiescent filaments are likely to be supported by more twisted flux ropes than short active-region filaments, which is consistent with observations.
Beamed Emission from a Neutron-star ULX in a GRRMHD Simulation
Authors: Abarca David , Parfrey Kyle , Kluźniak Włodek 
Published: August 2021

Abstract
We perform a global 2.5D general-relativistic radiation magnetohydrodynamic simulation of supercritical accretion onto a neutron star with a 2 × 1010 G dipolar magnetic field, as a model of a neutron-star-powered ultraluminous X-ray source (ULX). We compute a lower limit on the total luminosity of ∼2.5 L
Edd, and find the radiation to be highly beamed by the accretion disk outflows. The apparent isotropic luminosity, which is a function of the viewing angle, reaches a maximum above 100 L
Edd, consistent with the luminosities observed in ULXs.
High-energy Neutrinos from Stellar Explosions in Active Galactic Nuclei Accretion Disks
Authors: Zhu Jin-Ping , Wang Kai , Zhang Bing 
Published: August 2021

Abstract
Some catastrophic stellar explosions, such as supernovae (SNe), compact binary coalescences, and microtidal disruption events, are believed to be embedded in the accretion disks of active galactic nuclei (AGNs). We show high-energy neutrinos can be produced efficiently through pp interactions between shock-accelerated cosmic rays and AGN disk materials shortly after the explosion ejecta shock breaks out of the disk. AGN stellar explosions are ideal targets for joint neutrino and electromagnetic (EM) multimessenger observations. Future EM follow-up observations of neutrino bursts can help us search for yet-discovered AGN stellar explosions. We suggest that AGN stellar explosions could potentially be important astrophysical neutrino sources. The contribution from AGN stellar explosions to the observed diffuse neutrino background depends on the uncertain local event rate densities of these events in AGN disks. By considering thermonuclear SNe, core-collapse SNe, gamma-ray burst associated SNe, kilonovae, and choked GRBs in AGN disks with known theoretical local event rate densities, we show that these events may contribute to ≲10% of the observed diffuse neutrino background.
