Revisiting the Mousetraps Experiment: Not Just about Nuclear Chain Reactions
Authors: Perissi Ilaria , Bardi Ugo
Published: June 2022

We present here the first quantitative measurements of a classic experiment, that of the “mousetrap chain reaction”. It was proposed for the first time in 1947 to illustrate the chain reaction occurring in nuclear fission. It involves several spring-loaded mousetraps loaded with solid balls. Once one trap is made to snap, it releases two balls that may trigger the other traps. The result is a chain reaction that rapidly flares and then subsides as most traps have been triggered. The experiment has been popular as a scientific demonstration, but it does not seem that quantitative data were ever reported about it, nor that it was described using a model. We set out to do exactly that, and we can report for the first time that the mousetrap experiment can be fitted by a simple dynamic model derived from the well-known Lotka-Volterra one. We also discuss the significance of this experiment beyond nuclear chain reactions, providing insight into a variety of fields (chemistry, biology, memetic, natural resources exploitation) involving complex adaptive systems.

Arid and semiarid environments of Mediterranean countries suffer from scarcity of water resources, which limits their agriculture productivity. Using treated wastewater (TWW) is considered an alternative strategy for irrigation purposes in such areas. However, TWW contains substantial levels of heavy metals (HMs) and contaminants that pollute the environment and soil. The aim of this study is to evaluate the phytoremediation potential of six selected woody tree species under long-term irrigation with TWW. The concentration, bioaccumulation factor (BFC), translocation factor (TF), and comprehensive bioconcentration index (CBCI) of HMs were measured in the various parts (roots, bark, and leaves) of the studied tree species. The results show a general pattern of mineral accumulation in the roots and low translocation to the areal parts of various species. Cupressus sempervirens, which is a native species in Mediterranean environments, had higher TF values for Fe, Mn, Cu, Cr, Cd, and Pb metals in its areal parts compared to other tree species. The study shows that Ficus nitida has the potential to be a hyperaccumulator for Cd in its bark, with a TF value that exceeds 12. Deciduous trees species (Populus nigra and Robinia pseudoacacia) were found to have high TF values for Ni and Cd toward their areal parts, whereas a higher TF for Cr (1.21) was only found in P. nigra bark. Cupressus sempervirens had, significantly, the highest bark and leaf CBCI values (0.83 and 0.82, respectively), whereas Ficus nitida had the second-highest values in the bark and leaves (0.56 and 0.51, respectively). Therefore, Cupressus sempervirens and Ficus nitida are considered good hyperaccumulators for various HMs, and can be used for phytoremediation activities in polluted areas.
Environmental Concern, Environmental Knowledge, and Residents’ Water Conservation Behavior: Evidence from China
Authors: Li Yong , Wang Bairong , Cui Manfei
Published: June 2022

Water conservation represents a typical green behavior and a sustainable lifestyle. Understanding residents’ water conservation behaviors is a prerequisite for promoting more water savers. Using the snowball sampling technique, this study conducted a survey on a sample of 532 Chinese residents to investigate their water conservation behavior, i.e., reusing water in daily life. This study aims for examining psychological and knowledge factors on residents’ water conservation behavior in China using binary logistic regression. Results show that over half of the respondents (54%) have the habit of reusing water in their daily lives. Residents with stronger environmental concern and higher level of environmental knowledge are more likely to exhibit household water conservation in China. Additionally, environmental knowledge plays a positive moderating role in the relationship between environmental concern and water conservation behavior. Environmental knowledge serves as a catalyzer that facilitates the transformation from residents’ environmental concern into real water conservation behavior. Among the demographic variables, only income exerts significantly negative effect on residents’ water conservation behavior, and other variables (e.g., age and gender) fail to exert any influence on this behavior. This study contributes to the literature on environmental psychology and concludes with implications for water resource management.

Published: June 2022

Against the background of carbon neutrality, the power dispatching operation mode has undergone great changes. It not only gradually realizes the coordinated control of source–grid–load–storage, but also strives to realize the multi-level coordination of the transmission network, distribution network and microgrid. Disorderly charging and discharging of large-scale electric vehicles (EVs) will have a great negative impact on the distribution network, but aggregating EVs and guiding them to charge and discharge in an orderly manner will play a positive role in delaying investment in the distribution network. Therefore, it is urgent to adopt an effective scheduling control strategy for electric vehicle charging and discharging. First, a variety of indexes were set to analyze the influence of EVs access on distribution network and the correlation between the indexes. Then, by defining the EVs penetration rate and the load simultaneous rate, the charging load planning of EVs was calculated. Based on the simultaneous load rate, the regional electricity load plan was calculated, and a configuration model of distribution capacity suitable for charging loads in different regions was constructed. Finally, an optimal dispatch model for electric vehicles considering the safety of distribution network was proposed and the distribution transformer capacity allocation model was used as the optimization target constraint. Compared with most optimized dispatch models used to maximize aggregator revenues and reduce peak-to-valley differences and load fluctuations in distribution networks, this model could effectively reduce unnecessary investment while meeting regional distribution transformer needs and maintaining distribution network security. Taking the improved IEEE 34-bus systems as an example, the simulation analysis was carried out and the investment demand of distribution network under the condition of disordered and orderly charge and discharge was compared. The results show that the proposed optimal scheduling method can effectively reduce the load fluctuation of distribution network, keep the voltage offset within the allowable voltage deviation range, and can effectively delay the investment of distribution network.

Published: June 2022

Ideal single-cell viscometer has remained unachieved, leaving a gap in current palette of single-cell nanotools. Information of single-cell viscosity could contribute to our knowledge of fundamental biological processes, e.g., mass diffusion, biochemical interaction, and cellular responses to many diseases and pathologies. Although advances have been made to this end, existing methods generally suffer from limitations, e.g., low spatiotemporal resolution. Here, we describe a high spatiotemporal iontronic single-cell viscometer that operates upon a patch clamp integrated with double-barreled nanopores separated by a septum of ca. 32 nm. The system enables reversible electroosmotic manipulation of the adjacent small fluid bridging two nanopores, the viscous alternation of which could be sensitively monitored by the ionic responses. In practical cellular studies, significantly, our findings reveal not only the less deviated medium viscosities than those of lysosomes and mitochondria but also the highest viscosities in the near-nuclear region than those of mitochondrion-dense and lysosome-dense regions. This work has provided an accessible single-cell viscometer and enriched the armory of single-cell nanotools.

Effect of medium supplementation on very high gravity bioethanol fermentation using sago hampas hydrolysate as a feedstock
Authors: Muradi Nur Adila , Awang Adeni Dayang Salwani , Suhaili Nurashikin
Published: June 2022

Bioethanol fermentation under very high gravity (VHG) conditions by using sago hampas hydrolysate (SHH) supplemented with yeast extract as a fermentation medium has resulted in an incomplete metabolism of glucose, leading to relatively low bioethanol production in comparison to the theoretical titre. Therefore, additional supplementation of the fermentation medium is necessary to increase the yeast tolerance towards inhibitors and high concentration of glucose and bioethanol. This work investigates the effect of supplementing SHH media with various nutrients on bioethanol fermentation under VHG conditions. The nutrients included magnesium sulphate (0.12 g/L), urea (3 g/L), glutamic acid (5 g/L), and peptone (5 g/L). Our results showed that culture supplemented with peptone has significantly improved the yeast growth by 0.9-fold and glucose consumption efficiency by 10% compared to the control cultures. Besides that, the media formulation has also increased bioethanol production by 13%, with a maximum concentration of 126.20 ± 3.0 g/L. In general, the results suggest an improved formulation of fermentation medium consisting of SHH for bioethanol production under VHG conditions. These results will provide useful insights into the development of bioethanol production from sago-based feedstock in the future.

Un eslabón invisibilizado de la repartición vial bonaerense: el caminero (1910-1960)
Authors: Salomón Alejandra Laura
Published: June 2022

Bajo el impulso de la historia “al ras” del Estado, el propósito del trabajo es examinar el proceso de constitución y funcionamiento de la Dirección de Vialidad de la provincia de Buenos Aires mirando a sus sujetos. En el marco de un interés mayor sobre la relevancia socio-económica y la conservación de los caminos rurales, aquí se historizará un eslabón clave que ha pasado inadvertido para la historiografía –más enfocada en la obra pública, los expertos y la influencia de las asociaciones civiles en la configuración de políticas viales–: el caminero. El período que se pretende estudiar abarca desde la identificación del puesto en la década del diez hasta los años sesenta, cuando las precarias condiciones laborales, junto a las transformaciones socio-económicas, tecnológicas y estatales, condujeron a la desaparición paulatina del oficio. El recorrido por diversos repositorios documentales (legislación, actas de congresos viales, prensa, actas del Consejo de Vialidad, memorias gubernamentales, etc.) permitirá caracterizar su figura en tanto trabajador, a partir de la reconstrucción de su régimen laboral y los debates públicos suscitados por su situación social.

Companies must report compliance with environmental (E), social (S) and governmental (G) criteria in accordance with the disclosure rules (framework) for non-financial information. In our study, we examine the characteristics of ESG reports, whether they reflect the sustainability performance of individual market players, as well as what the most relevant problems are regarding this issue, not underestimating the fact that the most serious problem of corporate sustainability in 2022 was energy supply difficulties and price problems. In the course of our research, we have come to the conclusion that there are a number of parallel mandatory and optional disclosure requirements that require the publication of different data, so they are only partially suitable for comparing the sustainability activities of companies. Some of the corporate reports deal with ESG issues only in principle and only a small proportion reports on actions and results. We have also made suggestions that support the comparability of companies based on ESG indicators.

This paper overviews the theoretical and empirical research on tax amnesties and weighs their advantages and disadvantages. The paper questions if tax amnesties have any tax compliance impacts in the medium to long term as some papers have claimed or if they are more of a hindrance to tax compliance because of their unjust and degenerating effects. The paper examines the available data for the effects of tax amnesty programs on the ratio of tax revenues to GDP and the Gini coefficient for 12 countries focusing specifically on Turkey. The main aim of the paper is to identify better alternatives to tax amnesties in terms of both tax revenue and tax justice. The results of the study show that while the short-term revenue effect of tax amnesties is uncertain, their medium and long-term negative effects on tax justice and income distribution are almost certain. In addition, the study reveals that improving tax revenue is hardly the main reason behind most tax amnesties.

Hand-made printmaking is an effective power of art, which intensifies the human touch, unlike the digital process of mass production, which obliterates the human touch traces. In the scope of Arab printmaking artworks, this paper mainly aims to delve into the social commentary art, which involves employing rhetorical means to deliver commentary on important social issues in society. This paper also aims to provide insights into understanding the relationship between social commentary art and printmaking. Moreover, a historical outline of Arab printmaking is provided, which highlights the social commentary art in the Arab World. In its methodology, the study employed Feldman’s model of art criticism, which consists of description, analysis, interpretation, and judgment. Based on this model, several Arab artworks, considered social commentary printmaking art, were described, interpreted, and criticized. The study findings revealed that Arab artists like Laila Shawa, Dia Al-Azzawi, Ali Cherri, Kamal Boullata, and Nasser Al-Yousif have constructively documented important social and political issues and delivered effectively spirited printmaking artworks. Therefore, their artworks contributed to enlightening and deepening our understanding of these issues in the Arab region. The study's implication involved enriching our interpretation of social commentary and acknowledging the relationship between social commentary art and printmaking in the Arab World.

Authors: Gołąbek Michał , Rymarczyk Tomasz
Published: June 2022

The article describes the progress of construction and research works on ultrasound tomography. The devices allow for non-invasive measurements of various objects using ultrasonic low and high-frequency transducers. The first constructions were made in a dispersed system with active measurement probes using 40 kHz converters. The next constructions were centralized into one measurement system where the measurement probes were connected separately. As a result, the measuring range of the supported ultrasonic transducers with 300 kHz, 400 kHz and 1 MHz has been extended. Apart from transmission and reflection tomography, the latest designs allow for controlling the ultrasound beam (beamforming) and support transducers up to 5 MHz.

In the digitalized era of the information technology the expansion of the data usage is very high accounting for about enormous data transaction in day to day life. Data from different sources like sensors, mobile phones, satellite, social media and networks, logical transaction and ventures, etc add an gigantic pile to the existing stack of data. One of the best way to handle this exponential data production is the Hadoop network. Thus in the current scenario big industries and organizations rely on the Hadoop network for the production of their essential data. Focusing on the data generation and organization, data security one of the most primary important consideration was left unnoticed making data vulnerable to cyber attacks and hacking. Hence this article proposes an effective mixed algorithm concept with the Salsa20 and AES algorithm to enhance the security of the transaction against unauthorised access and validates the quick data transaction with minimal encryption and decryption time. High throughput obtained in this hybrid framework demonstrates the effectiveness of the proposed algorithmic structure over the existing systems
