Published: December 2021

Abstract
Background
The metal ion complexes of meropenem and cefixime with cadmium, silver, palladium, zinc, nickel, cobalt and copper were synthesized and characterized by UV, FTIR and H1-NMR spectrophotometry. The antibacterial effects of the complexes were studied using cup and plate method against S. aureus, B. subtilis, E. coli, P. aeruginosa and K. pneumoniae for normal and resistant strains of bacteria. The minimum inhibitory concentration of the metal ion complexes was determined by broth dilution method.

Results
UV spectroscopic studies suggested that meropenem ligand form complex with different metal ions and FTIR spectrum confirmed the proposed structure. Similarly, UV spectrum of cefixime metal ion complexes at λmax 202–295 nm and meropenem metal ion complexes at λmax 249–304 nm was observed in all the complexes. FTIR peaks for a proposed structure were observed in all the meropenem and cefixime metal ion, indicating the formation of complexes, and retained the functional groups of drugs. Meropenem as well as cefixime metal ion complexes exhibited more antibacterial activity against all the selected bacterial strains. Specifically, the lowest minimum inhibitory concentration against P. aeruginosa and K. pneumoniae was observed to be 100 and 150 μg/ml, respectively.

Conclusion
The present study concluded that the meropenem and cefixime metal complexes can exhibit the better treatment than individual drug on normal as well as resistant bacteria.

Published: December 2021

Abstract
Background
The recent pandemic of coronavirus disease 19 (COVID-19) has been causing intense stress among the global population. In the case of hospitalized and ICU-admitted COVID-19 patients with comorbidities, it has been observed that a major portion of them are diabetic. Therefore, researchers had indicated a link between diabetes mellitus (DM) and COVID-19. Furthermore, DM is a potential risk factor for the severity of COVID-19 cases. Thus, in this study, the correlation existing between diabetic patients and COVID-19 was summarized.

Main body of the abstract
Diabetic patients have a weaker immune system, less viral clearance rate, malfunctions of metabolic activity due to their high blood glucose level, and other associated problems. This does not increase the susceptibility for the patients to be infected with COVID-19. However, the severity of COVID-19 can worsen due to the comorbidity of DM.

Short conclusion
Proper management, appropriate use of drugs that do not increase the ACE2 expression, lowering blood glucose level, decreasing the susceptibility of SARS-CoV-2, and maintaining a healthy lifestyle could be effective.

Toward improved distributed acoustic sensing sensitivity for surface-based reflection seismics: Configuration tests at the Aquistore CO2 storage site
Authors: White Don , Bellefleur Gilles , Dodds Kevin , Movahedzadeh Zeinab 
Published: December 2021

Alternative fiber configurations have been tested in an attempt to improve the sensitivity of surface-deployed distributed acoustic sensing (DAS) fiber cables for the purpose of recording steep-angle P-wave reflections. Four alternative fiber configurations were deployed at the Aquistore CO2 storage site to record 401 dynamite shots during a 3D vertical seismic profiling survey. The test cable comprised horizontal configurations (straight fiber, helixes, and asymmetric helixes) buried in a shallow trench and vertical configurations (straight fiber and helixes) deployed in 3.5 m drillholes. Evaluation focused on deep reflections with two-way traveltimes of 0.8–1.8 s. All of the alternative fiber configurations increased the sensitivity relative to the horizontal straight fiber. Sensitivity was highest for the vertical straight fiber configurations and the asymmetric helixes with sensitivity increases of more than 10 and 5 dB, respectively, and amplitude-variation-with-offset behavior similar to that of a vertical-component geophone for reflections with incidence angles of 0°–15° at the surface and 0°–34° at the reflector. Modeling of the DAS responses explains the general pattern of sensitivity variability among the different configurations, but it does not explain the large range of observed sensitivities.

Published: December 2021

Aim of the studyThe aim of study was to evaluate communicative behaviors in close relationships of persons who dance Argentine tango and compare them with couples who do not undertake such activity. We also determined the types of psychological gender in our study groups and evaluated the differences between them.Subject or material and methodsThe study involved 78 persons (who dance Argentine tango and the control group). The set of administered tools included: Communication in Marriage and Partner Relationship Questionnaire, Psychological Gender Inventory and a self-designed demographic survey.ResultsOur data indicated that dancing tango was related to the overall quality of partner communication. Tangueros exhibited significantly better communicative behaviours and assessed their partners’ communicative behaviours better as well. We did not observe any differences in the distribution of psychological gender in the two groups.DiscussionOur analyses show that the hypotheses concerning the relationship of practising tango and the quality of communication in a close relationship are predominantly accurate. The dancers evaluate their partner’s contribution to communication significantly better- especially their support and commitment, and consider them less prone to diminish their worth. Argentine tango practitioners’ overall assessment of the quality of communication is also significantly higher - both when it comes to their own behavior, and the behavior of their partners.ConclusionsDancing tango helps to improve communication and can be an effective form of assistance for persons with difficulties in communication in partner relationships.

Published: December 2021

In this work, the magnetite nanoparticles (Fe3O4-NPs) synthesized using a simple, fast, and environmentally acceptable green approach. Gundelia Tournefortii Extract, an aqueous plant extract, was used for the first time in green synthesis to prepare nanoparticles as reducing, capping, and stabilizing agents. Such biomolecules as flavonoids, alkaloids, and antioxidants are found in the aqueous leaf extract, and their presence has been determined to have an important role in the synthesis of Fe3O4-NPs. The techniques used in this analysis include Fourier Transform Infrared, Scanning Electron Microscopy, Energy-Dispersive X-ray spectroscopy, X-ray Diffraction, Transmission Electron Microscopy, and Vibrating Sample Magnetometer. The Vibrating Sample Magnetometer demonstrated that the samples were superparamagnetic, with a magnetization value of 48.6 emu/g. The prepared nanoparticle was applied to remove Chrystal Violet (CV), Malachite Green(MG), and Safranin (S) dyes from prepared aqueous solutions with the adsorption capacity of 13.9, 15.6, and 14.4 mg/g respectively.

Challenges of the Filter Paper Suction Measurements in Geosynthetic Clay Liners: Effects of Method, Time, Capillarity, and Hysteresis
Authors: Acikel A. S. , Bouazza A. , Singh R. M. , Gates W. P. , Rowe R. K. 
Published: December 2021

Abstract
Time and method dependencies, lack of sufficient capillary connections, and wetting-drying hysteresis may cause inaccurate results from filter paper tests (FPTs) when used for suction measurements of geosynthetic clay liners (GCLs). These limitations of the filter paper method for suction measurements of GCLs were investigated using initially dry contact, initially wet contact, and noncontact FPTs. Wetting-drying hysteresis was observed in the initially dry contact and noncontact FPTs and was significantly higher in the latter. The initially wet contact and initially dry contact FPTs were reliable in measuring matric and total suction, respectively. These two methods can provide suction measurements from both the cover and the carrier geotextile sides of the GCLs (i.e., from the hydratable surfaces of the GCL after installation on site), thus allowing suction measurements without impacting the integrity of the geotextile-bentonite-geotextile structure. Suction measurements on a granular bentonite-based GCL showed higher time dependency compared with powdered bentonite-based GCLs. For the specific GCLs and conditions tested, the woven and nonwoven scrim-reinforced geotextile structure causes pronounced capillary break effects on the hydratable surface of GCL. In contrast, the woven geotextile structure has a minimal impact. When the FPT procedures are applied to GCLs, the interpretation of the results requires careful consideration of the method and time dependencies, wetting-drying hysteresis, capillary breaks, and how the measurements of total or matric suction are performed.

Authors: Holzer Werther , Fernandes Marina Pires 
Published: December 2021

Este trabalho objetiva o resgate da memória e cultura da população friburguense através do olhar da paisagem sob o patrimônio residencial de Nova Friburgo, RJ. Tendo em vista a vulnerabilidade dos imóveis residenciais acerca do processo de renovação, atribuído ao desenvolvimento da cidade e a diversidade da arquitetura dado à sua colonização suíça e alemã, e posteriormente acrescida de imigrantes outras nacionalidades, o património da cidade se mostra diversificado e presente, porém pouco preservado. A partir dos conceitos de paisagem abordados por Augustin Berque e Pierce Lewis parte-se de uma ótica de que o patrimônio residencial compreende a base do cotidiano da população e que, por meio do olhar para essas edificações pela da definição de paisagem-marca e paisagem-matriz e os axiomas, dos respectivos autores, entende-se os processos de relação da população e a cidade, além de seu estudo e formação, e cria-se uma abordagem para a preservação desses imóveis. Busca-se trazer à superfície, por meio da habitação, o significado de patrimônio, como algo que foi preservado, não somente pelas questões estéticas mas pelo seu valor imaterial. Para isso, buscou-se criar um material que apresente essas edificações utilizando os guias da paisagem apresentados por Lewis instigando um senso crítico e de análise a respeito das mesmas, a partir de um catálogo dos bens, com foco nas vilas operárias, dispostos por meio de um mapa interativo, que apresenta os imóveis georreferenciados, buscando suprir a lacuna de informação de forma clara e acessível.

Published: December 2021

Data of pregnancy course and delivery in 3 patients with hepatolenticular degeneration (GLD) a rare disease of autosomal recessive inheritance pattern are presented. In one case GLD was diagnosed prior pregnancy and treatment with cuprenil was continued during pregnancy. No progressive GLD clinical symptoms were observed. However pregnancy and delivery appeared to provoke GLD typical manifestations in other two patients. They have not got specific treatment with cuprenil during pregnancy as disease was diagnosed only after delivery.
Deliveries in patients with GLD were successful and the newborns were healthy. No evidence of cuprenil teratogenic effect on fetus was revealed in the first case. This GLD is not contraindication for successful pregnancy but it is necessary to use cuprenil for prevention of disease exacerbation.
