The harmful impact of mercury on biological systems is of great concern. Regardless of the efforts made by the regulating agencies, a decrease in Hg2+ concentration has not been realized, and hence mercury accumulation in the environment remains of utmost concern. Designing novel and efficient probes for recognition and detection of toxic metals in environmental samples has been of primary importance. Among the available techniques, probe designs involving the study of spectral properties has been preferred because of its obvious ease of instrumentation. Furthermore, occurrence of significant changes in the visible portion of electronic spectra enables detection by the naked eye, thereby endorsing the preference for development of probes with off-on binary responses to aid in the in-field sample analysis. The prominence is further streamlined to the use of fluorescence to help characterize on-response the cellular detection of Hg2+ with ease. In order to overcome the problem of developing efficient probes or sensors bearing fluorescence on-response mechanism that can work effectively in physiological conditions, various methodologies, such as chemo-dosimetric reaction mechanisms for the designing of new luminescent ligands, are being adopted. Additionally, modified charge transfer processes are also being considered for optical detection of the mercury (II) ion. In this review, all such possible techniques have been discussed in detail.

Published: October 2021

The identification of microscale oil structures formed from deposited oil droplets on the filter front face of a coalescence filter medium is essential to understand the initial state of the coalescence filtration process. Using µ-CT imaging and a deep learning tool for segmentation, this work presents a novel approach to visualize and identify deposited oil structures as oil droplets on fibers or oil sails between adjacent fibers of different sizes, shapes and orientations. Furthermore, the local and global porosity, saturation and fiber ratios of different fiber material of the oleophilic filter medium was compared and evaluated. Especially the local and global porosity of the filter material showed great accordance. Local and global saturation as well as the fiber ratios on local and global scale had noticeable differences which can mainly be attributed to the small field of view of the µ-CT scan (350 µm on 250 µm) or the minimal resolution of approximately 1 µm. Finally, fiber diameters of the investigated filter material were analyzed, showing a good agreement with the manufacturer’s specifications. The analytical approach to visualize and analyze the deposited oil structures was the main emphasis of this work.
Sustainability Practices in Working Contexts: Supervision, Collective Narrative, Generative Humour, and Professional Respect
Authors: Cadei Livia , Serrelli Emanuele , Simeone Domenico
Published: October 2021

Research literature and field experience reveal that jobs in social education—just like other jobs with a high interpersonal involvement—feature a high risk of job burnout. By necessity, work organizations in social education have developed a definite set of practices to support their workers and provide occasions for mutual support. Here we analyze four of these practices—supervision, collective narrative, generative humour, and professional respect—and suggest ways in which organizations in other sectors may consider importing them to increase their own organizational sustainability. We also present an analysis of workers’ second-level skills (such as narrative skills, reflexive skills, team working skills) that are related to sustainability practices: on the one hand they allow the individual worker to effectively take part and contribute, on the other hand their development is stimulated by such participation. Organizational sustainability is in fact to be considered a positive collaboration between individuals and organization, rather than a one-way, top-down condition. Increases in sustainability may result from cascading effects triggered by management decisions as well as by workers’ individual and collective actions.
Interval Type-2 Fuzzy Logic Anti-Lock Braking Control for Electric Vehicles under Complex Road Conditions
Authors: Lv Linfeng , Wang Juncheng , Long Jiangqi
Published: October 2021

To simultaneously track the ideal slip rate and realize ideal energy recovery efficiency under different complex road conditions, an electro-hydraulic compound anti-lock braking system based on interval type-2 fuzzy logic control strategy and its corresponding braking torque allocation strategy have been developed for electric vehicles. The proposed interval type-2 fuzzy logic controller aims to calculate the ideal total braking torque by four steps, namely, fuzzification, fuzzy inference, type reduction, and defuzzification. The slip rate error and the change rate of slip rate error are utilized as inputs in the fuzzification, and then, the membership degree interval of fuzzy variables determined by the upper and lower membership functions is used to calculate the activation degree interval of different fuzzy rules in the fuzzy inference process, which enhances the anti-interference ability to external uncertainties and internal uncertainties. The braking torque allocation strategy is proposed to maintain the maximum energy recovery efficiency on the premise of safe braking. The software of MATLAB/Simulink is applied to simulate the process of anti-lock braking control under two complex road conditions. Simulation results corroborate the proposed interval type-2 fuzzy logic anti-lock braking control system can not only obtain better slip rate control effect and outstanding robustness but also achieve ideal regenerative braking energy recovery efficiency under both joint-μ and split-μ road surfaces.

In the framework of geosite management, specific targeted symbols for geomorphological legends are still lacking. Concerning geosites of geomorphological interest, geomorphological mapping requires targeted symbols in relation to goals and applications, either concerning geomorphic hazards and risk detection or the enhancement of resources, in particular those related to cultural heritage and, hence, geoheritage. A new methodology for mapping geo(morpho)heritage on geomorphological maps is presented in this paper. Nine iconic examples from the Italian landscape, selected in different morphogenetic and morphoclimatic contexts, are proposed to test the methodology in relation to point, polyline and polygon features. Moreover, guidelines for mapping are suggested according to the importance of the site and to the complexity of processes characterizing each case study.
Getting Young People to Farm: How Effective Is Thailand’s Young Smart Farmer Programme?
Authors: Jansuwan Para , Zander Kerstin K.
Published: October 2021

In 2014, the Thai government initiated the Young Smart Farmer (YSF) programme to counter the decline in the number of young people involved in farming. The YSF programme has three desired outcomes: first, to increase participants’ financial independence; second, to enhance the adoption of innovative farming methods; and third, to retain participants in the long-run by satisfying them. This study aimed to evaluate if these outcomes have been achieved. A Propensity Score Matching (PSM) method was applied to analyse the data collected from programme participants (61 responses) and non-participants (115 responses) through a survey in the Prachin Buri province in Thailand. Participation was determined by education, farmland size, farming experience, and challenges to farming. Most participants (~79%) stated that they were satisfied with the programme; however, the programme did not increase financial independence and the adoption of innovative farming methods. As such, the programme might not be very effective in motivating young people to continue, return to, or enter farming. We recommend that the programme can be improved by adjusting training and field trips to meet the needs of participants in different production systems. The programme should also be expanded beyond providing knowledge and information, and it could offer additional monetary and non-monetary support to participants, such as loans for technology investments needed for farm expansion and competitive advantages.

Viral infections have been associated with poor pregnancy outcomes. We investigated the magnitude of rubella virus (RV), dengue virus (DENV), Zika virus (ZIKV) and human cytomegalovirus (HCMV) among symptomatic pregnant women in rural and urban areas of Mwanza. A cross-sectional study was conducted between July 2017 and April 2018 in Mwanza. A rapid immunochromatographic test was done to detect ZIKV IgM and IgG as well as DENV IgM and IgG antibodies. A multiplex_RT-PCR was also done to detect the viral RNA genome. Enzyme immunoassays were done to detect RV and HCMV. Out of 171 participants, 1 (0.6%) was found to be seropositive for ZIKV_IgM antibodies, while 5 (2.9%) were ZIKV_IgG seropositive. DENV seropositivity was 9 (5.3%) and 3 (1.8%) for IgM and IgG, respectively, with all being PCR negative. Two participants (1.2%) were RV_IgM seropositive. 100% were HCMV_IgG seropositive and none was HCMV_IgM seropositive. Among 70 women with high HCMV_IgG titters, 10 (14.3%) had a low avidity index, indicating recent infections. Residing in rural areas (p = 0.044) and advanced age (p = 0.024) independently predicted ZIKV/DENV seropositivity. A substantial proportion of pregnant women had markers for viral infections. There is a need for introducing routine screening and monitoring pregnancy outcomes of positive cases to establish the relationship of these viruses and adverse pregnancy outcomes in endemic areas.
Relativistic Fractional-Dimension Gravity
Authors: Varieschi Gabriele U.
Published: October 2021

This paper presents a relativistic version of Newtonian Fractional-Dimension Gravity (NFDG), an alternative gravitational model recently introduced and based on the theory of fractional-dimension spaces. This extended version—Relativistic Fractional-Dimension Gravity (RFDG)—is based on other existing theories in the literature and might be useful for astrophysical and cosmological applications. In particular, in this work, we review the mathematical theory for spaces with non-integer dimensions and its connections with the non-relativistic NFDG. The Euler–Lagrange equations for scalar fields can also be extended to spaces with fractional dimensions, by adding an appropriate weight factor, and then can be used to generalize the Laplacian operator for rectangular, spherical, and cylindrical coordinates. In addition, the same weight factor can be added to the standard Hilbert action in order to obtain the field equations, following methods used for scalar-tensor models of gravity, multi-scale spacetimes, and fractional gravity theories. We then apply the field equations to standard cosmology and to the Friedmann-Lemaître-Robertson-Walker metric. Using a suitable weight vtt, depending on the synchronous time t and on a single time-dimension parameter αt, we extend the Friedmann equations to the RFDG case. This allows for the computation of the scale factor at for different values of the fractional time-dimension αt and the comparison with standard cosmology results. Future additional work on the subject, including studies of the cosmological late-time acceleration, type Ia supernovae data, and related dark energy theory will be needed to establish this model as a relativistic alternative theory of gravity.

Published: October 2021

The development of an effective vaccine against SARS-CoV-2 marks one of the highest priorities during the ongoing pandemic. However, recruitment of participants for clinical trials can be challenging, and recruitment failure is among the most common reasons for discontinuation in clinical trials. From 20 May 2020, public announcements about a planned phase I trial of the vaccine candidate MVA-SARS-2-S against SARS-CoV-2 began, and interested individuals started contacting the study team via designated e-mail. All emails received from these individuals between 20 May 2020–30 September 2020 were assessed. Of the 2541 interested volunteers, 62% contacted the study team within three days after the first media announcement. The average age was 61 years (range 16–100), 48% of volunteers were female and 52% male. A total of 274, 186, and 53 individuals, respectively, reported medical pre-conditions, were health-care workers, or had frequent inter-person contacts. In conclusion, we report a high number of volunteers, with a considerable percentage stating factors for an elevated risk to acquire COVID-19 or develop severe disease. Factors such as media coverage and the perception of a disease as an acute threat may influence the individual’s choice to volunteer for a vaccine trial. Our data provide first important insights to better understand reasons to participate in such trials to facilitate trial implementation and recruitment.

Published: October 2021

Due to the open structure of wireless charging systems, foreign objects are inevitably involved. In the process of energy transfer, the intervention of metal foreign objects will cause the system to deviate from the normal operating point and even cause safety accidents. Therefore, metal foreign objects detection (MOD) technology is of considerable importance. In this paper, a metal foreign object detection system of a wireless power transfer (WPT) system based on the symmetrical detection coil was designed, and a MOD method based on frequency scanning is proposed. The coil size of the WPT system was designed based on SAE-J2954 standard. In addition, the suitable detection coil was installed at the transmitting coil. The system model was established in ANSYS simulation software, and 5 cm × 5 cm copper sheet and iron sheet were used as the metal to be detected. The result shows that the self-induction of the detection coil at the position of the foreign object can achieve a fluctuation of 52.46% and −34.72%, and the resonant frequency of the detection system is offset by 24.7% and −18.82%, respectively. Finally, the experimental platform of MOD system was built, and the effectiveness of the system was verified.

Seguindo a tendência mundial, nas últimas décadas, o Brasil vem passando por um processo de transição demográfica, epidemiológica e nutricional, caracterizado pelo declínio da taxa de fecundidade, diminuição no ritmo do crescimento populacional, aumento da longevidade, progressiva urbanização, maior exposição a comportamento alimentar e estilo de vida inadequado além de mudanças nos padrões saúde/doença. As modificações na estrutura da dieta da população têm levado a um aumento significativo do consumo de alimentos processados e ultraprocessados, ricos em açúcares, gorduras, corantes e sódio e também na redução do consumo de alimentos naturais. A alimentação inadequada associada ao estilo de vida sedentário tem resultado em um aumento de indivíduos com excesso de peso e susceptíveis a Doenças Crônicas Não Transmissíveis (DCNTs). Diante disso, o objetivo do estudo foi identificar evidências disponíveis na literatura acerca da influência da transição alimentar e nutricional sobre o aumento da prevalência das DCNTs. Para tanto, foi realizada uma revisão narrativa com dimensão temporal entre 2000 e 2021 nos idiomas português e inglês. Os dados obtidos evidenciaram que as mudanças no padrão alimentar associadas com o sedentarismo tem repercutido em um aumento considerável da prevalência de obesidade, Diabetes Mellitus (DM), Doenças Cardiovasculares (DCVs), Hipertensão Arterial Sistêmica (HAS) e dislipidemias. Em consequência dos hábitos alimentares inadequados e estilo de vida sedentário, verifica-se a necessidade das pessoas serem orientadas quanto a uma alimentação saudável, e também estimuladas a praticarem exercício físico regularmente para ter uma melhor qualidade de vida.

Authors: Patrikeeva Mariya V.
Published: October 2021

The author of the article examines the reflection of the events of the Crimean War of 1853–1856 in the plots of Russian fables. The article analyses the system of characters, plot dominants of fables, demonstrates the possibilities of this genre in describing the military clash of Russia with hostile states. The author of the article points to a common task that unites the plots of the fables of different poets (it was obligatory to emphasise the confrontation between the sides of the military conflict), but at the same time considers the content and stylistic features of each fable separately. Noting the specificity of the fable genre of the period of the Crimean campaign of 1853–1856, the author of the article points out its connection with the traditions laid down in Russian literature by Ivan Krylov, which were reflected in the plot, stylistics and numerous allusions.

Published: October 2021

the article will focus on the history of the first publication of the novel “Doctor Zhivago” by Boris Pasternak, on its influence on the formation of opinion about Boris Pasternak as a truly major prose writer, as well as on the potential role in the further receipt of the Nobel Prize by the author in 1958. As one knows, the first publication took place in Italy. It is from Italian cultural figures Giangiacomo Feltrinelli (the first publisher of the novel) and Pietro Antonio Zveteremich (its translator) it depended on how the novel would be received abroad, where Boris Pasternak had not been well-known by the late 1957 – the Swedish Academy initially refused to nominate the writer as a Nobel laureate due to insufficient fame in wide literary circles. After the publication of “Doctor Zhivago”, it was essential to determine what the content of the first reviews of this work would be. The paper reviews the first reviews of the novel in the Italian press, in particular, the discussion that unfolded in the independent monthly magazine “Il Ponte”. Such well-known cultural figures in Italian literary circles as Guglielmo Petroni, Carlo Cassola, and Manlio Cancogni spoke out. Their opinions were not ignored, they were accepted by the general public.

Published: October 2021

Physical activity is often considered as an essential component of a healthy lifestyle and is required to be studied in detail. It is especially important to study this issue in reference to the population of older age groups. The aim of the research was to analyse subjective and objective characteristics of physical activity in population of older age groups. Methods of sociological survey, parametric and nonparametric statistics were used in the work. Data on the characteristics of physical activity were obtained on the basis of a study of 1,045 subjects of both genders aged 60 years and older. The participants of the survey did not have any kinds of disability and were not engaged in any sport activities. According to the results of the study, the age of the men and women was the determinant of assessing a level of physical activity. The average level of physical activity prevailed in men aged 60–74 years. Low levels of physical activity prevailed in men aged 75 years and older. Women had mostly low levels of physical activity. Comparison of subjective and objective characteristics of physical activity showed a significant overestimation of subjective characteristics of high levels of physical activity and underestimation of the prevalence of low levels of physical activity in both men and women. As a result of gender comparisons, it was revealed that men aged 60–74 years overestimated their level of physical activity by a fourfold, while women were more objective assessing their level of physical activity.

La guerra biológica y química en la Grecia antigua (Siglox VIII - IV A. C.)
Authors: Blanco Rodríguez Susana
Published: October 2021

Cuando escuchamos la expresión "guerra biológica o bacteriológica" pensamos en un tipo de ofensiva en la que se utilizan armas que contienen virus o bacterias capaces de infligir un daño masivo sobre el ejército o la población civil y que su invención es algo más o menos reciente Sin embargo, los griegos de la antigüedad ya conocían los efectos de determinados venenos y sustancias, ya fuesen de origen vegetal o animal, producían en el cuerpo humano. Utilizarlos en el terreno militar fue cuestión de tiempo. En contra de lo que se podría pensar, construir armas químicas y biológicas no era algo muy complicado ni exigía grandes conocimientos: la mayoría de estas armas tenían una tecnología sencilla, lo que no les restaba eficacia.

Las fuentes griegas apenas mencionan este tipo de armas que no sólo fueran utilizadas por los humanos; en la esfera mítica también encontramos ejemplos de su empleo. Este recelo podría deberse a que se consideraban armas crueles y deshonrosas, que simbolizaban la guerra despiadada , astuta, secreta y al margen de todo precepto moral;  además solían provocar heridas dolorosas e incurablesy, en el peor de los casos, una muerte angustiosa.

En definitiva, este tipo de armas contradecían el ideal griego de guerra justa, respetuosa y sujeta a unos principios éticos aprobados por la sociedad. Sin embargo, en la Grecia Antigua, el principio del orden y justicia de la guerra, era frágil y recurrir a tretas inteligentes que sorpendieran al enemigo, en el fondo, estaba bien visto. Por lo tanto, establecer dónde estaba el límite entre lo aceptable y lo reprobable era difícil de precisar y es justamente en este contexto donde se encuadrarían las armas biológicas, cuyo uso en Grecia se remotaría a fechas tempranas y a los relatos míticos.

Comunicación global en el 68 Mexicano. El caso del diario español ABC
Authors: Vieira Cid Javier
Published: October 2021

El propósito principal de este artículo consiste en tratar de analizar la estrategia comunicativa que emprendió el diario español ABC para informar sobre la realidad del movimiento estudiantil mexicano de 1968. Esta experiencia se inserta en la lógica contestataria global que durante ese año convulsionó al mundo. Se caracterizó por su profundo rechazo al gobierno autoritario de Díaz Ordaz, planteando la génesis de un proceso que pretendía transformar la vida política del país. Partiendo de la línea editorial del diario, conservadora y fuertemente vinculada al discurso oficialista del franquismo, pretendemos visibilizar cuales fueron los principales enfoques comunicativos que se utilizaron para narrar las jornadas de agitación estudiantil en México.

Authors: Yateem CH. A. M. , Mustafa K. N. , Alkass J. E.
Published: October 2021

Twenty one Awassi lambs (4 month old and 23.59 ± 031 kg body weight) were used to investigate the effect of different levels of protein on growth, carcass traits, body composition, digestibility and some blood parameters. The lambs were divided equally and randomly and penned individually into three treatment groups, and fed ad lib on low protein (129.1 T1) medium protein (140.6 T2) and high protein (151.1 T3, g/kg DM). After 72 days of fattening, 5 lambs from each treatment were chosen randomly and slaughtered. The result showed that lambs fed on T3 diet had significantly (P<0.05) higher daily gain (210.83 g), better feed efficiency (4.8 kg/kg), higher dressing percentage (51.67 %), and rib eye area muscle (12.05 cm2) than those fed in T2 and T3, as well as digestibility coefficient of dry matter, organic matter, crude protein, and total digestible nutrient (TDN) was also numerically higher in group fed (151.1 g/kg DM) as compared with lambs received low or medium level of protein. It could be concluded that the high dietary protein level produce the better performance, carcass traits and nutrient digestion of lambs.
A COMPARATIVE STUDTY ON GROWTH, CARCASS TRAITS AND BODY COMPOSITION OF AWASSI AND KARADI LAMBS RAISED UNDER TWO LEVELS OF FEEDING AND SLAUGHTERED AT DIFFERENT WEIGHTS: 1- GROWTH PERFORMANCE AND CARCASS TRAITS

Published: October 2021

Sixteen weaned (3.5-4 months) entire male lambs from each of Awassi and Karadi were weighed and randomly divided equally into two groups to receive concentrate (16% crude protein and 2769 kcal energy) either ad libitum or 3% of their body weights, and to be slaughtered at 36 or 44 kg. Results revealed that overall means of daily gain in weight, dressing percentage based on slaughter and empty body weight, rib eye area and fat thickness were 0.258±0.01 kg, 46.54± 0.49%, 54.35 ± 0.40%, 14.98 ±0.44 cm2 and 2.86 ± 0.12 mm, respectively. It seems that Awassi lambs significantly surpass Karadi lambs in dressing percentage based on slaughter weight and had thicker subcutaneous fat, only. Also, lambs fed ad lib excell significantly those lambs fed 3% in daily gain in weight, dressing percentage based on slaughter weight, and fat thickness. Lambs slaughtered at 44 kg had significantly higher dressing percentage, rib eye area and fat thickness.

This study was aimed  to evaluate the toxic properties of phenylmethane on internal organs and liver enzymes (Alkaline phosphatase (ALP) and Alkaline serum transaminase (AST)changes in mice. Thirty albino mice randomly divided equally into 2 groups, each group contains (15) animals as following: 1st group was administrated orally (0.2 mg / kg B.w) of  Phenylmethane daily for (8)weeks, 2nd group was considered as negative control group. Finally all animals euthanized and sample of blood were taken for biochemical examination and histopathological specimens were taken from liver, kidney and brain. Results revealed that phenylmethane pointedly enlarged in the level of liver enzyme after 8 weeks  that ALP (88.50 ± 1.01), AST (250.20 ± 0.92) compare with control(50.00 ± 0.85), (231.80 ± 1.40). The histopathological lesions showed that the animals exposed to toxic dose of phenylmethane  was characterized by inflammatory reaction, hemorrhage, congested blood vessels, necrosis, fibrosis and granuloma in internal organs. In conclusion, phenylmethane  had possess toxic effects for internal organs in mice. To avoid its harm on human, the use of phenylmethane should be expertise.
