Published: November 2023

Abstract
This study investigates the impact of gamma irradiation on the properties of waste coffee grounds (WCG)/high-density polyethylene (HDPE) composites. The composites were manufactured with 20 wt% of unirradiated and irradiated WCG at 10 and 20 kGy doses of gamma radiation. Through the utilization of a two-roll mill followed by a hydraulic press. The properties of the composites were analyzed through several methods, including contact angle measurements, hardness and tensile tests, thermogravimetric analysis (TGA), and scanning electron microscopy (SEM), in order to understand the influence of gamma irradiation. The addition of WCG decreased the tensile strength of the composite. However, gamma irradiation at 10 and 20 kGy led to substantial improvements in thermal stability and tensile strength compared to unirradiated samples. The SEM images showed the alterations within the fiber-matrix interface that corroborated the enhanced tensile properties after the treatment. While FTIR spectra confirmed the changes in functional groups of WCG caused by the irradiation process, gamma irradiation treatment not only increases fiber-matrix adhesion but also significantly improves the water resistance of the composites. These results suggest that gamma irradiation can be used for the modification of agro-waste materials as a beneficial process and the fabrication of high-performance, environmentally friendly composites.

Abstract
The synthesis of an efficient adsorbent to remove chromium ions from water is challenging. Therefore, in this study, a new nanomagnet composite (Fe3O4/biochar/ZIF-8) was synthesized by a one-pot hydrothermal method using a metal–organic framework (MOF, ZIF-8) as a sacrificial template, citrus peels as a source of biochar, and iron oxide nanoparticles for magnetization. The synthesized nanocomposite showed a high efficiency toward the adsorption of Cr(vi) ions. The adsorption study showed that the experimental data were well-described using the Langmuir isotherm model and pseudo-second-order model. According to the Langmuir model, the adsorption capacities toward Cr(vi) adsorption were 77 and 125 mg·g−1 for Fe3O4/biochar and Fe3O4/biochar/ZIF-8, respectively, indicating the role of MOF in improving the adsorption performance. The Fe3O4/biochar/ZIF-8 showed an excellent adsorption performance in the presence of coexisting ions at a wide pH range using different eluents to study reusability up to five successive cycles. We can conclude from this study that this nanoadsorbent is a promising material for removing pollutants from environmental water samples.

Published: November 2023

Abstract
Visiting wine tourism events is an attractive part of a trip for holidaymakers and day visitors. Thus, wine tourism is an important niche market for Germany with its 13 wine regions. Experiences play an increasingly important role in the consumption of tourism services. Therefore, it is also important to organize wine tourism events in an experience-oriented way. The present research design uses the KANO model to determine the requirements for experience staging at wine events from the customer’s point of view. The aim of the study is to provide wineries and other wine tourism providers with recommendations for experience staging in order to increase the attractiveness of the events and to improve the economic success.
A doubly mononuclear cobalt(II) complex constructed with azide anions and a new coordination mode of the 2-(2-pyridylmethylamino) ethanesulfonic acid ligands: structure, conformation comparison and Hirshfeld surface analysis
Authors: Chen Shu-Hui , Song Hai-Tao , Xu Xia 
Published: November 2023

Abstract
A doubly mononuclear cobalt(II) complex [Co(Hpmt)2(N3)2]2 (1) (Hpmt = 2-(2-pyridylmethylamino)ethanesulfonic acid; N3 = azide anion) has been synthesized and structurally characterized. Single-crystal X-ray diffraction analysis showed that 1 has crystallized in orthorhombic crystal system, Cmc21 space group. In the two independent and identical complexes, the cobalt(II) centers are both hexa-coordinated in distorted CoN6 octahedrons. The reduced Schiff base ligand Hpmt displayed a new coordination mode of bidentate chelate (κ
2-N,N′). The careful comparisons between Hpmt upon coordination and as free acid form demonstrated that the conformation flexibility might be responsible for its multiple coordination modes. The N–H⋯O and C–H⋯N hydrogen bonds constructed the 3D network, and this mainly agreed with the Hirshfeld surface analysis results.
Electrical and magnetic properties of MF/CuAl nanocomposites
Authors: Roumaih Khaled 
Published: November 2023

Abstract
This study investigated the effects of CuAl2O4 (CuAl) on four types of spinel ferrites: CoFe2O4 (CoF), NiFe2O4 (NiF), MgFe2O4 (MgF), and ZnFe2O4 (ZnF) with regards to their electrical characteristics and microscopic magnetic behavior. According to the Seebeck coefficient (φ), the nanocomposites have a mixture of positive and negative charge carriers, except for CoF/CuAl, which has a positive charge carrier only. Depending on the temperature, the
DC
conductivity of all MF/CuAl nanocomposites has a conductor and semiconductor behavior. The dielectric properties were studied at different frequencies (100–10^8 Hz) and temperatures (300–673 K). The results demonstrated how temperature and frequency affect
AC
operating mechanisms. The high values of dielectric loss for all nanocomposites confirm their applicability in high-frequency microwave devices. The impedance study revealed that the equivalent circuit for all MF/CuAl nanocomposites is a mixture of R, L, and C. Temperature-magnetization graphs were obtained for all nanocomposites, indicating ferrimagnetic behavior except ZnF/CuAl. The magnetic transition temperature (T
Cm), the Curie–Weiss constant (θ
CW), and the effective magnetic moments (μ
eff) for all nanocomposites were determined. The MF/CuAl samples were analyzed using ESR spectroscopy at room temperature. The spectra were distorted but remained distinct, potent, and sweeping. The g-factor values deviate from the free electron, which suggests that the Fe3+–O–Fe3+ superexchange interaction has changed. In addition, the interaction effect between MF and CuAl is discussed.

Published: November 2023

Abstract
Die Fertigung kundenindividueller elektronischer Bauteile ist durch volatile Losgrößen und heterogene Automatisierungsgrade geprägt. Trotz verfügbarer Assistenzsysteme können zeitbezogene Abweichungen oft erst mit hohem Aufwand in der Produktionsleitung identifiziert und geeignete Maßnahmen verzögert eingeleitet werden. Um eine proaktive Steuerung auf Feldebene zu realisieren, bedarf es einer teilautomatisierten Lösung. Process Mining stellt einen datenbasierten Ansatz dar, um den organisatorischen und zeitlichen Produktionsablauf aufzudecken. Anhand prädiktiver Ergebnisse im operativen Betrieb können somit geeignete Maßnahmen bereitgestellt werden. In diesem Beitrag wird ein anwendungsorientierter Ansatz zur vorhersagenden Prozesssteuerung von Fertigungsabweichungen unter Einsatz von Process Mining vorgestellt.

Authors: Cunha Vivian Fukumasu da , Coimbra Susana , Fontaine Anne Marie , Neubern Maurício da Silva , Scorsolini-Comin Fabio 
Published: November 2023

Objective: to identify and collect recommendations for teaching religiosity/spirituality in undergraduate Nursing courses of nurses working in a Hospital. Method: this is a qualitative study, with 34 nurses interviewed. The research corpus was fully transcribed and submitted to content analysis. Results: the religiosity/spirituality theme was absent in the graduation of most of professionals. They mentioned the restricted preparation to deal with human issues and for being a dimension that offers a resource to face the challenges of the daily life of the profession. What mitigated this gap was that some professionals have their own religious/spiritual beliefs, which have often guided how this religious/spiritual support is provided in health care. Conclusions: participants suggest the presence of religiosity/spirituality teaching in nursing graduation effectively and practically, not only theoretically reinforce its importance. Taking religiosity/spirituality content to undergraduate courses can be sensitive to the holistic needs of patients/users and even the professionals themselves.

Published: November 2023

AbstractObjective:This study was aimed at investigating the association between diabetes mellitus and susceptibility to pancreatic cancer by using Mendelian randomization (MR) methods and an extensive human genome-wide association study (GWAS) dataset.Methods:The publicly accessible MR Base database was used to obtain the complete genome, relevant research findings, and summary data pertaining to diabetes mellitus and pancreatic cancer. Genetic variables, specifically single-nucleotide polymorphisms closely associated with diabetes mellitus, were selected for analysis. Four methods—inverse variance weighted (IVW) analysis, weighted median analysis, weighted mode, and MR-Egger regression—were used. Statistical analysis was conducted to explore the potential association between diabetes mellitus and susceptibility to pancreatic cancer.Results:The results of the IVW analysis (OR = 11.56519319, 95% CI 1.275068624–104.8992116, P = 0.0296) indicated a significant causal relationship between diabetes and elevated pancreatitis risk. Furthermore, the absence of horizontal pleiotropic effects (Egger intercept = 0.29, P = 0.384) and heterogeneity (P = 0.126) suggested that the observed association was not influenced by confounding factors. Sensitivity analysis and other statistical methods also supported the conclusion that genetic pleiotropy did not introduce bias to the findings.Conclusion:A causal relationship exists between diabetes mellitus and the occurrence of pancreatic cancer. People with diabetes mellitus are at high risk of pancreatic cancer and should receive early screening. The IGF signaling pathway may be a key mediator of the effects of diabetes on pancreatic cancer pathogenesis.
