Published: October 2021

Some environmental chemicals capable of interfering with the endocrine regulation of energy metabolism and the structure of adipose tissue in the function of the reproductive, immune, cardiovascular and other systems are called endocrine disruptors or disruptors. According to the WHO definition, the term «endocrine disruptors» means: «Exogenous substances or mixtures thereof that alter the function (s) of the endocrine system and, as a result, cause adverse effects in the intact organism or in its offspring, or (sub) population.» This includes compounds to which humanity is exposed in daily life as a result of their use in pesticides, herbicides, industrial and household products, plastics, detergents, refractory impregnations and as ingredients in personal care products. This review will present the latest scientific data on various ERs, such as persistent organic pollutants (POPs): pesticides (mirex, chlordecane, endosulfan, hexachlorobenzene-HCB dichlorodiphenyltrichloroethane-DDT and its metabolites), industrial chemicals (bisphenol A, polybrominated ether -PBDE, polychlorinated biphenyls-PCB, nonylphenol, dioxins, perfluorooctanoic acid-PFOA, phthalates), pharmaceuticals (diethylstilbestrol-DES). ERs are regarded as compounds that cause obesity, since they have the ability to influence cellular processes associated with adipose tissue, initiating changes in lipid metabolism and adipogenesis. Analysis of scientific materials on this issue indicates that ERs are ubiquitous in the environment and have a detrimental effect on the health of animals and mankind. The scientific and practical interest in this article is based on the growing statistics of the development of such socially significant pathologies as obesity and related diseases, including diabetes mellitus, metabolic syndrome, cardiovascular diseases, menstrual irregularities, as well as cancer and infertility, for of which obesity is a risk factor.

Published: October 2021

Este artigo objetiva discutir o que sentimos falta com relação às mudanças no sistema educacional brasileiro, levando em conta os dados existentes nos últimos governos (Bolsonaro, Dilma e Lula), especificamente sobre a Educação Básica e Superior. Metodologidamente, é um ensaio teórico (pesquisa bibliográfica e documental) com abordagem de análise crítica. A justificativa para esse estudo são as políticas promovidas pelo governo atual que provocam, em nível nacional e internacional, um amplo debate na mídia e nas comunidades científicas. Além de uma possibilidade de refletir sobre o contexto da pandemia e as inseguranças geradas pela ausência de ações governamentais. O levantamento identifica que não há um sistema nacional que coordene as responsabilidades pela educação brasileira. Além disso, há extrema confusão no atual governo, falta investimento público, disputa de um projeto político-ideológico, entre outros fatores que impossibilitam a gestão da educação no país de forma democrática.

Published: October 2021

Abstract
The effects of ventilation and sucrose concentration on proliferation and organogenesis of pistachio cutting and photosynthetic performance of two in vitro cultures of pistachio rootstocks have been assessed. The apical leaf buds (Qazvini and UCB1 cultivars) were cultured in filter vessels containing Murashige and Skoog medium supplemented with 0, 10, 15, and 30 g L
−1 of sucrose. The plants treated with 10, 15, and 30 g L
−1 sucrose showed no significant differences regarding the measured traits; therefore, this treatment was set aside from the final statistical analyses. Use of different ventilation systems showed to be suitable for increasing the growth of pistachio. Referring to root production difficulties under in vitro cultivation of pistachio, ventilation increased the root production and length. However, the full ventilation system was more effective in improving the growth properties. Regression between fluorescence feature vs root length showed that F
v/F
m had a significant positive relationship with root length. Stomata of cell parameters under ventilation systems improved compared to no ventilation, which was highly similar to the trend in the greenhouse. The overall results indicated that low concentrations of sucrose (e.g., 10 g L
−1) and full ventilation are recommended for producing high quality and vigorous pistachio plantlets under in vitro conditions.
Bullshit, trust, and evidence
Authors: Briciu Adrian 
Published: October 2021

Abstract
It has become almost a cliché to say that we live in a post-truth world; that people of all trades speak with an indifference to truth. Speaking with an indifference to how things really are is famously regarded by Harry Frankfurt as the essence of bullshit. This paper aims to contribute to the philosophical and theoretical pragmatics discussion of bullshit. The aim of the paper is to offer a new theoretical analysis of what bullshit is, one that is more encompassing than Frankfurt’s original characterization. I part ways with Frankfurt in two points. Firstly, I propose that we should not analyze bullshit in intentional terms (i.e. as indifference). Secondly, I propose that we should not analyze it in relation to truth. Roughly put, I propose that bullshit is best characterized as speaking with carelessness toward the evidence for one’s conversational contribution. I bring forward, in the third section, a battery of examples that motivate this characterization. Furthermore, I argue that we can analyze speaking with carelessness toward the evidence in Gricean terms as a violation of the second Quality maxim. I argue that the Quality supermaxim, together with its subordinate maxims, demand that the speaker is truthful (contributes only what she believes to be true) and reliable (has adequate evidence for her contribution). The bullshitter’s main fault lies in being an unreliable interlocutor. I further argue that we should interpret what counts as adequate evidence, as stipulated by the second Quality Maxim, in contextualist terms: the subject matter and implicit epistemic standards determine how much evidence one needs in order to have adequate evidence. I contrast this proposed reading with a subjectivist interpretation of what counts as having adequate evidence and show that they give different predictions. Finally, working with a classic distinction, I argue that we should not understand bullshit as a form of deception but rather as a form of misleading speech.
Strengthening Disaster Response Through Analysis of Crime During Hurricane Ike
Authors: Augusto Daniel 
Published: October 2021

AbstractThis study uses time series analysis in an effort to inform disaster response efforts by identifying changes to Houston crime during Hurricane Ike. The results indicate that Burglaries increased significantly by 305% during Ike. Aggravated Assaults also increased significantly, but Theft and Auto Theft decreased by 37% and 16% respectively. Several other crimes revealed no significant differences during Ike. These findings, when combined with other research, show that Burglaries consistently increase during natural disasters, and Emergency Support Function 13 (ESF-13) responders should plan for that reality. This study also provides some other considerations for ESF-13 management related to disaster preparedness training and exercises. Additionally, the study provides evidence of the need for ESF-13 responders and reinforces their importance as a key form of capable guardianship under Routine Activities Theory.

Published: October 2021

Abstract
The Mode-I interlaminar fracture characteristics of aramid fabric andcarbon fabric reinforced epoxy composites along with the influence of SiC particle content were explored. Double cantilever beam (DCB) tests were performed in accordance with ASTM D 5528 for the purpose of examining the behavior of Mode-I delamination. The results showed that, the adhesion strength of an SiC particle within an aramid/ epoxy composite system was better than that within a carbon/epoxy composite system. The highest values of Mode-I fracture toughness of an aramid fabric/epoxy specimen and a carbon fabric/epoxy specimen were 1391 J × m-2 and 701 J × m-2 with SiC particle contents of 10 wt.-% and 5 wt.-%, respectively. The micrographs from optical and scanning electron microscopes verified the enhancements of Mode-I interlaminar fracture toughness behavior.

AbstractA wide variety of near-field optical phenomena are described by the interaction of dipole radiation with a nanophotonic system. The electromagnetic field due to the dipole excitation is associated with the Green’s function. It is of great interest to investigate the dipole interaction with a photonic system and measure the near-field Green’s function and the quantities it describes, e.g., the local and cross density of optical states. However, measuring the near-field Green’s function requires a point-source excitation and simultaneous near-field detection below the diffraction limit. Conventional single-tip near-field optical microscope (SNOM) provides either a point source excitation or amplitude and phase detection with subwavelength spatial resolution. The automated dual-tip SNOM, composed of two tips, has overcome the experimental challenges for simultaneous near-field excitation and detection. Here, we investigate the dipole emission in the near-field of a dielectric metasurface using the automated dual-tip SNOM. We have analyzed the near-field pattern and directional mode propagation depending on the position of the dipole emission relative to the metasurface. This study is one further step toward measuring the dyadic Green’s function and related quantities such as cross density of optical states in complex nanophotonic systems for both visible and near-infrared spectra.
Thermal conductivity and dynamic viscosity of mono and hybrid organic- and synthetic-based nanofluids: A critical review
Authors: Amin At-Tasneem Mohd , Hamzah Wan Azmi Wan , Oumer Ahmed Nurye 
Published: October 2021

Abstract
Thermal conductivity and dynamic viscosity are two critical properties of nanofluids that indicate their heat transfer performance and flow. Nanofluids are prepared by dispersing mono or several organic or synthetic nanoparticles in selected base fluids to form mono or hybrid nanofluids. The qualitative and quantitative stability measurement of nanofluids will then be addressed, followed by a detailed discussion on how the dispersion of nanoparticles in water (W), ethylene glycol (EG), and the mixture of W:EG 60:40% by volume affects the thermal conductivity and dynamic viscosity ratio. The data comparison demonstrated that the thermal conductivity ratio increases with increasing normalized concentrations, the bulk temperature of nanofluids, and the smaller nanoparticle size. The dynamic viscosity ratio is multiplied by the normalized concentration increase. Nevertheless, as the bulk temperature climbed from 0 to 80°C, the dynamic viscosity ratio was scattered, and the dynamic viscosity ratio trend dropped with increasing particle size. While the majority of nanofluids enhanced thermal conductivity ratio by 20%, adding carbon-based nanoparticles to synthetic nanofluid increased it by less than 10%. The disadvantage of nanofluids is that they multiply the dynamic viscosity ratio of all nanofluids, which increase power consumption and reduces the efficiency of any mechanical system.

AbstractGlobal overpopulation, industrial expansion, and urbanization have generated massive amounts of wastes. This is considered as a significant worldwide challenge that requires an urgent solution. Additionally, remarkable advances in the field of biomedicine have impacted the entire spectrum of healthcare and medicine. This has paved the way for further refining of the outcomes of biomedical strategies toward early detection and treatment of different diseases. Various nanomaterials (NMs) have been dedicated to different biomedical applications including drug delivery, vaccinations, imaging modalities, and biosensors. However, toxicity is still the main factor restricting their use. NMs recycled from different types of wastes present a pioneering approach to not only avoid hazardous effects on the environment, but to also implement circular economy practices, which are crucial to attain sustainable growth. Moreover, recycled NMs have been utilized as a safe, yet revolutionary alternative with outstanding potential for many biomedical applications. This review focuses on waste recycled NMs, their synthesis, properties, and their potential for multiple biomedical applications with special emphasis on their role in the early detection and control of multiple diseases. Their pivotal therapeutic actions as antimicrobial, anticancer, antioxidant nanodrugs, and vaccines will also be outlined. The ongoing advancements in the design of recycled NMs are expanding their diagnostic and therapeutic roles for diverse biomedical applications in the era of precision medicine.

AbstractBackgroundTraining a non-dominant hand is important for rehabilitating people who are required to change handedness. However, improving the dexterity in using chopsticks with a non-dominant hand through training remains unclear. This study is aimed to measure whether chopstick training improves non-dominant hand chopstick operation skills and leads to acquisition of skill levels similar to those of the dominant hand.MethodsThis single-blinded randomized controlled trial enrolled 34 healthy young right-handed subjects who scored >70 points on the Edinburgh Handedness Questionnaire Inventory. They were randomly allocated to training or control groups. The training group participated in a 6-week chopstick training program with the non-dominant left hand, while the control group did not. Asymmetry of chopstick operation skill, perceived psychological stress, and oxygen-hemoglobin concentration as a brain activity measure in each hemisphere were measured before and after training.ResultsParticipants in the training group had significantly lower asymmetry than those in the control group during the post-training assessment (F[1,30] ≥ 5.54,p≤ 0.03, partialη2≥ 0.156). Only perceived psychological stress had a significantly higher asymmetry during the post-training assessment (t[15] = 3.81,p< 0.01).ConclusionSix weeks of chopstick training improved non-dominant chopstick operation skills, and a performance level similar to that of the dominant hand was acquired.
Spherical and cylindrical conductive thermal diodes based on two phase-change materials

Published: October 2021

Abstract
We theoretically studied and optimized the thermal rectification of spherical and cylindrical conductive thermal diodes operating with two phase-change materials (PCMs), whose thermal conductivities significantly changes in a narrow interval of temperatures. This is done by deriving simple analytical expressions for the heat flows, temperature profiles and rectification factors of both diodes. It is shown that diode geometry has a significant impact on the heat flows and temperature profiles, but not so much on the thermal diode rectification factor. Optimal rectification factors of 63.5 and 63.2% are obtained for the spherical and cylindrical thermal diodes operating between the terminals of VO2 and polyethylene with a temperature difference of 150 K spanning the metal–insulator transition of both PCMs. These similar rectification factors could be enhanced even more with a phase-change material exhibiting higher contrast thermal conductivity than the ones in the present study. The obtained results can thus be useful to guide the development of PCMs capable of optimizing the rectification of conductive heat flows with different geometries.

The effects of video gaming on academic effectiveness of higher education students during emergency remote teaching
Authors: Papp Dávid , Győri Krisztina , Kovács Karolina Eszter , Csukonyi Csilla 
Published: October 2021

Abstract
The pandemic caused a new digital scheme of work to be implemented in higher educational institutes to avoid physical contact, which is referred to as emergency remote teaching in the literature (Hodges, Moore, Lockee, Trust, & Bond, 2020). The inevitable consequence of emergency remote teaching (later on ERT) was that the students’ inter-and extra organisational relationships decreased significantly (Pusztai & Győri, 2021). Based on the results of previous studies, we know that the lack of student relationships is strongly related to ineffectiveness (Astin, 1993; Pusztai, 2015; Tinto, 1975), which was also identified during the period of ERT (Pusztai & Győri, 2021). In the current study, firstly, we hypothesised that the students’ social interactions, which were accomplished by video gaming, could compensate for isolation (Pisan, 2007) and improve their effectiveness. Secondly, we hypothesised that video gaming might prove ineffective due to stressful and uncertain periods as well as avoidance of activity. In our study, we applied database analysis (Learning Alone database, N = 677) and half-structured interviews (N = 19). In the quantitative sample, we identified that increased gaming time (compared to the time spent before the pandemic) was related to persistence reduction, whereas similar results were obtained with the reduced playing time. In addition, the interview participants reinforced that they used video gaming as a tool to maintain their relationships during ERT, and they tended to do so in their relationships with other students as well. Thus it can be said that video gaming is an extracurricular activity that could affect academic effectiveness positively and negatively at the same time.
Tonal peaks in the spontaneous speech of vantage level Hungarian learners of Spanish
Authors: Pálvölgyi Kata Baditzné 
Published: October 2021

Abstract
This paper reports on a two-part research project, conducted in order to see how Hungarian learners with at least vantage level of Spanish realize melodic peaks in their Spanish utterances. First, we are focusing on the tonal and distributional characteristics of melodic peaks, taking into consideration the proportion of the rise in f0 with respect to the previous syllable and examining if the affected syllable is lexically stressed. Second, the range of the tonal rise until the first peak of the utterance is analyzed. The method applied in both cases is Cantero Serena’s Prosodic Analysis of Speech (2019), which represents intonation by objectively comparable standardized melodic curves. The differences found in the speech of Hungarian learners as compared to native Spanish speakers have not proved to be significant in the aspects analyzed here. The main finding of the research is that native Spanish speakers tend to realize the first peak of their declarative sentences as the highest f0 point of the utterance, whereas this is less typical in the oral production of Hungarian learners of Spanish.
