At mining of minerals by an open-cut method with the use of highly productive mining equipment the contamination of the environment by dust emitted during various mining works takes place. Especially, at excavation of rock mass without application of means of dust suppression, the most intensive dust emission is observed. The main way to reduce dust emission is to wet the rock mass. However, the fight against dust is complicated during the development of sulfide ores prone to spontaneous combustion. The matter is that water may intensify the process of oxidation and self-heating of sulfide ores in the pile. In this connection in such conditions the traditional method of hydro-dusting cannot be used as it takes place in open pits, mined out in normal mining and geological conditions. Therefore, when developing sulfide ores prone to spontaneous combustion, for dampening it is recommended to use solutions having along with the effectiveness of dedusting and antioxidant properties, i.e. complex action. The expression for determining the specific flow rate of fluid (q), necessary to reduce dustiness to MPC is proposed. The equation for determining the moisture content of the rock mass at a depth corresponding to a certain point in time is proposed. The solution of this equation has allowed to receive the formula, allowing at known values of parameters of height of humidified heap H, m; maximum humidity of ore φm, %; natural humidity φ_e %; volume weight, kg/m3, characterized by relative constancy for the specific conditions of the pit, to determine approximately the specific consumption of the solution for its penetration to the center of self-ignition, depending on the change in the depth of the center. For practical use the highest calculated value of the specific flow rate of the solution, providing the reduction of air dustiness to MPC and the penetration of the solution to the center of self-heating, is taken.

El artículo presenta una propuesta de pauta para la observación del ambiente en el aula, validada a través de juicio de expertos. Este instrumento permite observar las subdimensiones: física, funcional, temporal y relacional. El ambiente físico del aula observa los materiales e implementos utilizados como recursos; por otra parte, el ambiente observado desde aspectos funcionales, se encuentran en relación con la forma en que han sido dispuestas las actividades en el espacio y su orientación hacia un objetivo, por lo que el espacio en cuanto a su funcionalidad es un colaborador del logro de objetivos.
Lo temporal dice relación con el ritmo de la clase y se desarrollan las actividades. El ritmo de la clase puede ser, por ejemplo, muy rápido, impidiendo que los estudiantes procesen información. Finalmente, lo relacional corresponde a la forma en que los sujetos interactúan en el espacio.
Este instrumento puede ser utilizado para realizar análisis holístico, o bien, para analizar cada subdimensión por separado. Se sugiere, además, complementar la información recogida en esta pauta con otro instrumento de registro abierto, como notas de campo o fichas.
Los resultados que arroja la evaluación del desempeño docente en Chile, indican que la promoción de la participación de los alumnos en clases es baja, llegando a un 35%, esto significa que solo este porcentaje de docentes lo desarrolla.
Se hace necesario conocer entonces distintas experiencias y realidades que muestren la forma en que se gestiona el ambiente en el aula, para el logro de los objetivos de aprendizaje.

Introduction: Traditional medicines (TMs) play a vital role in the public healthcare system of Tanzania and other sub-Saharan countries. The community has been advocating for greater recognition and formalization of this sector.
Aims: This study aimed to evaluate the community's knowledge and views on formalization to maximize the beneficial use of TMs in Tanzania.
Methodology: A cross-sectional survey was conducted among the university community, involving a total of 458 students and staff from three major public universities in Tanzania. Participants were interviewed regarding their history, knowledge, and inclination towards using TMs. They were also asked about their opinions on community involvement and the necessity of strengthening the formalization of education and usage in this field.
Results: The results revealed that 84.7% of the participants had utilized TMs, with 71.6% currently using them and 16.8% using them on a regular basis. Furthermore, 30.5% of the participants agreed that the community is aware of the importance of TMs, while 18.8% believed that the community receives adequate education regarding their significance. Additionally, 33.6% indicated that the government recognizes and promotes the importance of TMs. The study also found strong community support for introducing TM practitioners who can attend to patients and provide TMs. There was also strong support for formalizing education on TMs within the Tanzanian education system.
Conclusion: The study's findings underscore the significance of recognizing and leveraging traditional medications to improve public health and preserve the benefits of local knowledge.
The Mechanism of the Photodimerization of [60]Fullerene Derivatives: It is Still a Charge Separation Followed by a Back Transfer!

Published: July 2023

AbstractHerein, we present a systematic study of the photochemical behavior of a set of fullerene compounds bearing various organic addends attached to the fullerene cage. It has been shown that the yield of photodimerization products strongly depends on the structure and electronic properties of the material, primarily the electron affinity (acceptor strength) of the modified fullerene core. This finding being inconsistent with the conventional [2+2]cycloaddition mechanism and pointed to an alternative pathway. This proposed pathway involves photoinduced charge separation followed by back charge transfer events leading to the efficient generation of triplet excitons, which are responsible for the formation of dimerized species. The light‐induced charge separation pathway was confirmed by electron spin resonance spectroscopy and was supported by theoretical calculations. The revealed mechanism allows one to control the photochemical behavior of the fullerene derivatives via rational structural engineering: some of the compounds were shown to be fully resistant to photodimerization, which makes them promising candidates in the development of stable organic photovoltaics. Furthermore, this approach could be used to suppress back charge transfer in donor‐acceptor blends and hinder the formation of triplet excitons which represents one a major energy loss channel in the current generation of organic solar cells.

AbstractEfficient blue phosphors remain a formidable challenge for organic light‐emitting diodes (OLEDs). To circumvent this obstacle, a series of Ir(III)‐based carbene complexes bearing asymmetric di‐N‐aryl 6‐(trifluoromethyl)‐2H‐imidazo[4,5‐b]pyridin‐2‐ylidene chelates, namely, f‐ct6a‒c, are synthesized, and their structures and photophysical properties are comprehensively investigated. Moreover, these emitters can undergo interconversion in refluxing 1,2,4‐trichlorobenzene, catalyzed by a mixture of sodium acetate (NaOAc) and p‐toluenesulfonic acid monohydrate (TsOH·H2O) without decomposition. All Ir(III) complexes present good photoluminescence quantum yield (ΦPL = 83–88%) with peak maximum (max.) at 443–452 nm and narrowed full width at half maximum (FWHM = 66–73 nm). Among all the fabricated OLED devices, f‐ct6b delivers a max. external quantum efficiency (EQE) of 23.4% and Commission Internationale de L'Eclairage CIEx,y coordinates of (0.14, 0.12), whereas the hyper‐OLED device based on f‐ct6a and 5H,9H,11H,15H‐[1,4] benzazaborino [2,3,4‐kl][1,4]benzazaborino[4′,3′,2′:4,5][1,4]benzazaborino[3,2‐b]phenazaborine‐7,13‐diamine, N7,N7,N13,N13,5,9,11,15‐octaphenyl (ν‐DABNA) exhibits max. EQE of 26.2% and CIEx,y of (0.12, 0.13). Finally, the corresponding tandem OLED with f‐ct6b as dopant gives a max. luminance of over 10 000 cd m−2 and max. EQE of 42.1%, confirming their candidacies for making true‐blue OLEDs.

Published: July 2023

AbstractActuators based on stimuli‐responsive polymers (SRP) have great potential applications in soft robots, remote control, artificial muscle, etc., but their practical robustness is usually limited by mechanical strength and environmental tolerance. Inspired by the unique “muscle‐cartilage” structure of Skate fin, a general strategy is developed for improving the mechanical strength and environmental tolerance of SRP actuators by introducing a twill cotton fabric as the supporting cartilage. Besides, benefiting from the special twill pattern and micro‐nano substructure of the fabric layer, the prepared SRP actuator possesses anisotropic actuation and fast wet recovery, which further enriches its versatility. This SRP actuator can be extended to complicated actuation systems with programmable motion series or cyclic task execution by simply heat‐soldering or assembling with other functional components. The method provides an idea in simultaneously addressing the practical robustness and rich extensibility of SRP actuators, facilitating their application in complex environments or multi‐tasking scenarios.

AbstractUO2F2 abstracts F− anions from TlF in liquid ammonia solution and the compound [Tl2(NH3)6][{UO2F2(NH3)}2(μ‐F)2] is formed. The compound has been characterized by single crystal X‐ray diffraction, Raman spectroscopy and quantum‐chemical calculations for the solid state. Quantum‐chemical investigation of the [{UO2F2(NH3)}2(μ‐F)2]2− anion showed that the U−(μ‐F)−U σ‐3c‐4e‐bond is essentially ionic. The [Tl2(NH3)6]2+ cation shows a thallophilic Tl⋅⋅⋅Tl interaction. Fluoride ion affinities (FIAs) were calculated for different UO22+ species [UO2Fx]2−x and [UO2Fx(NH3)5−x]2−x with x=0 to 4.

Published: July 2023

AbstractThis paper describes a pragmatic Model‐Based Systems Engineering (MBSE) approach to reduce dependence on traditional documents and manage complexity of the electrified powertrain system. The approach enables requirements flow‐down from an upper abstraction layer to the lower one(s) with stepwise analysis and design for a holistic system architecture of the system of interest. This approach is employed in the Nissan Powertrain development, which aims to solve challenges due to the traditional documents systems engineering (SE) approach to complex systems. This paper describes an MBSE approach developed for Nissan‐7 methodology that focuses on knowledge capture, fast feedback on requirements and design, and early verification and validation. The significant benefits of using an MBSE approach over a traditional documents SE approach are: a holistic view of system architecture, knowledge reusability, communicability, and adaptability to new technologies. This paper presents proof of concept example projects that have demonstrated that it is viable to use this approach and apply it to an actual development for future work.

AbstractRecently, with the growing demand for qualitative values such as wellbeing, development and implementation of systems considering societal needs. This paper presents an approach of concept verification and validation for the proposed “Eating‐Together” system that aims to enhance connectivity among neighbors of busy urbanites in Japan. The study utilized three psychological scales, including the Positive and Negative Affect Schedule (PANAS), General Self‐Efficacy Scale (GSES), and Social Worth as Measures of Performance (MOP). In developing the concept of the System of Interest (SOI), four main aspects were identified as mission requirements. The prototype was built based on the final concept model, and nine tests were conducted with 15 hosts and 31 guests. The questionnaires were administrated three times: before, immediately after, and two weeks after the event. The results indicated that the prototype successfully met all of the mission requirements, providing an improved method to estimate the otherwise unmeasurable elements.
Life span‐associated ferroptosis‐related genes identification and validation for hepatocellular carcinoma patients as hepatitis B virus carriers
Authors: Weng Weijie , Zhang Defa , Li Shuang 
Published: July 2023

AbstractBackgroundHepatitis B virus (HBV)‐infected population accounts for approximately 50% of all hepatocellular carcinoma (HCC) cases and has a relatively poor prognosis. Although the significant role of ferroptosis in the development and therapeutic response of various cancers has been validated, the key ferroptosis‐related genes (FRGs) on the stratification of HBV‐associated HCC are still unclear.MethodsThrough the random forest, GSVA and Cox regression analyses, we established a comprehensive prognostic system covering multiple FRGs to elevate the predictive accuracy for the survival rate of HBV‐related HCC using information obtained from public databases. The association between key FRGs and the immune microenvironment was evaluated, and the molecular mechanism was identified by GSEA and SNV analyses. Finally, the differential expression of key FRGs was validated by immunohistochemistry staining of patient tissue microarrays.ResultsWithin the top 10 key FRGs, EPAS1 and GABARAPL1 were taken as protective factors, and SQLE, RAD51AP1, RPL8, CAPG, RRM2, SLC1A5, SLC38A1, and SRC were the other eight dangerous markers. Cox regression analysis combined with clinicopathological features indicated the independent prognostic efficacy of GSVA complex score based on these FRGs. In addition, key FRGs were related to immune and metabolic‐related functions. Especially, the immunohistochemical analysis of SQLE in 50 clinical samples showed significantly higher expression in HBV+ HCC tissues.ConclusionsThese results indicate that 10 FRGs may be potential biomarkers and therapeutic targets for long‐term survival in HBV‐related HCC.

AbstractWe establish new results on the ‐approximation property for the Banach operator ideal of the unconditionally p‐compact operators in the case of . As a consequence of our results, we provide a negative answer for the case of a problem posed by Kim. Namely, the ‐approximation property implies neither the ‐approximation property nor the (classical) approximation property; and the ‐approximation property implies neither the ‐approximation property nor the approximation property. Here, denotes the p‐compact operators of Sinha and Karn for . We also show for all that there is a closed subspace that fails the ‐approximation property for all .
