The Impact of Substitution of Diphenyl Dialumene on the Molecular Structure and Energetic Properties
Authors: Babikir Salma , Abdalla Sahar , Mohamed Wefag , Umar Yunusa 
Published: April 2024

The molecular structure, energetic properties, electronic, and vibrational spectroscopy of meta-substituted phenyl dialumene, DPD (Ar–Al=Al–Ar; Ar of the formula C6H5X2, where X = H, CH3, NH2, OH, F, Cl, Br, NO2, and COOH) are investigated by DFT. The singlet states of unsubstituted and substituted DPD adopt trans-planar geometry, while the triplet states adopt non-planar trans-bent geometry. The Al=Al bond length of unsubstituted DPD-H in a singlet state is calculated to be 2.734 Å, and there is no systematic and significant change upon substitution (2.734–2.744 Å). The substitution affects the absolute energy, ionization potential, electron affinity, and reorganization energy. The wavelength of maximum absorbance of DPD-H is determined to be 443 nm, and the substitute analogues DPD-X (X = OH, F, Cl, Br, NO2, CHO, COOH) show a hypsochromic shift, while DPD-CH3 and DPD-NH2 exhibit a bathochromic effect. The HOMO to LUMO+1 transition is the major transition for the meta-substituted DPD, except for X=NO2, where the transition is to LUMO+2. Considering the reorganization energy values, meta-substituted DPD can be useful as hole transporters. In addition, the theoretical data will aid in predicting the behavior of this class of compounds, facilitating the design and synthesis of similar compounds with desired properties.

Published: April 2024

Codoping of nitrogen and copper into zirconium titanate composite (Cu-N-codoped ZrTiO4) was carried out through a sol-gel process. This study aimed to investigate the effect of copper and nitrogen dopants on the photocatalytic activity of ZrTiO4 composite in degrading phenol. To prepare the composite, an aqueous suspension of zirconia (ZrO2) alongside a fixed amount of urea and various amount of copper sulfate was added dropwise into diluted titanium(IV) tetraisopropoxide (TTIP) in ethanol. The composites were calcined at temperatures of 500, 700, and 900 °C. Fourier-transform infrared spectrophotometry (FTIR), X-ray diffraction (XRD), scanning electron microscopy with energy dispersive X-ray (SEM-EDX) mapping, and specular reflectance UV-visible spectrophotometry (SR UV-vis) were used for their characterization of composite. The photocatalytic activity was evaluated by adding the composite into a 10 mg L−1 phenol solution for various irradiation time spans. The remaining concentration of phenol solution was determined by absorption at 269 nm. Cu-N-codoped ZrTiO4 composite containing 5% Cu calcined at 500 °C demonstrated the highest observed rate constant and a significant band gap decrease from 3.13 to 2.68 eV.

Published: April 2024

Background: Examination gloves are used in health facilities to protect health professionals and patients from the risk of infection and reduce opportunities for cross-transmission of infectious microorganisms. Poor-quality examination gloves can expose health professionals to infectious diseases such as Covid-19, Hepatitis, HIV/AIDS, and other contagious diseases. Hence, this study aimed to assess the quality of examination gloves in health facilities in Addis Ababa.
Methods: A cross-sectional study design was employed. The examination gloves were collected from randomly selected health facilities in Addis Ababa. The gloves were examined following standard procedure in the Ethiopian Food and Drug Authority. Holes in the examination gloves were detected using the watertight (leakage test) and geometrical dimensions such as thickness, width, and length were measured.
Results: A total of 2500 selected examination gloves were collected between Feb 10 and Feb 20, 2021. The gloves were sampled from health facilities in Addis Ababa. From the total samples collected, only 2280 examination gloves of five different brands were tested, which makes the response rate 91.2%. The proportion of gloves with holes detected ranged from 5.7% to 21.9%. Overall, only 0.17% and 3.2% of the gloves had width and length below standard, respectively. None of the gloves tested in this study had a thickness below the standard.
Conclusions: All brands of examination gloves tested had a higher hole (leakage) rate than the acceptable quality limit. This implies there is a substantial risk of infectious disease transmission to health professionals and patients in healthcare settings. Hence, regulatory enforcements need to be strengthened across the life cycle of the product.

Published: April 2024

In today’s business era & competition in pharmaceutical industries, post-approval evaluation & cGMP compliance plays an important role. Regulatory approval is a critical milestone in the lifecycle of pharmaceuticals and medical devices, ensuring their safety, efficacy, and quality before entering the market. A regulatory affair is a bridge between pharma industry and health authorities.
Post-Approval function in Regulatory Affairs department plays a major role in supporting continuous commercialization and facilitating for its implementation. This function are responsible to provide strategic regulatory inputs to plant team on their proposals and to facilitate smooth submission followed by acceptance/ approval. In the USA, the Food and Drug Administration (FDA) governs the regulatory process, employing a thorough and well-defined approach to submission evaluation. Europe, with the European Medicines Agency (EMA) at its helm, utilizes a centralized procedure for marketing authorization, harmonizing regulations across member states. Meanwhile, Health Canada oversees regulatory activities in Canada, emphasizing a risk-based approach to ensure public safety.
Post-approval submission management is equally vital in maintaining compliance and ensuring ongoing product safety. This paper delves into the strategies and best practices for handling post-approval changes, variations, and renewals. It examines the role of regulatory intelligence, life cycle management, and effective communication with regulatory agencies to navigate the evolving regulatory landscape.
By comparing and contrasting the regulatory processes in the USA, Europe and Canada, this overview aims to provide valuable insights for pharmaceutical and medical device companies seeking global market access. Understanding the intricacies of regulatory submission and post-approval submission management across these regions is essential for successful product development, commercialisation and long-term regulatory compliance.
PRODUÇÃO E CIRCULAÇÃO DE CONHECIMENTO EM TEMPOS DE MERCANTILIZAÇÃO E NEGACIONISMO: DESAFIOS EDITORIAIS
Authors: Barbosa de Oliveira Ines 
Published: April 2024

Descobrimos recentemente no Brasil, e algo chocados, que os preços cobrados dos autores, por algumas das principais editoras científicas do mundo beiram os dez mil dólares. Enquanto isso, cresce no mundo, a perspectiva de uma ciência aberta, acessível a todos, transparente em suas avaliações por pares e em relação aos dados das pesquisas que estão na origem dos artigos. Este cenário de embates e contradições nos permite tratar dos desafios editoriais que estão colocados àqueles que atuam na área a partir de diferentes ângulos. O objetivo é contribuir para as reflexões, mais do que oferecer respostas, levantar possibilidades de mudança e apontar dificuldades. Didaticamente separados em seções, os temas se articulam e caminham juntos, como diferentes expressões do momento político, científico e econômico que o mundo ocidental vivencia.
Assim, o artigo aborda, em primeiro lugar, a questão da mercantilização e da influência das desigualdades econômicas sobre a circulação do conhecimento, incluindo no debate as questões que envolvem a ideia do inglês como língua franca na perspectiva da “internacionalização subalterna”. Em seguida, trataremos dos riscos políticos e sociais tanto da exclusão quanto o fato desta exclusão abrir espaço para a desinformação e o negacionismo e seu outro lado, os ataques às universidades e pesquisadores no Brasil.
A especificidade do cenário nacional nas ciências humanas e sociais e as responsabilidades editoriais que a ela se associam fecha o artigo, buscando situar alguns dos principais problemas que nos atingem, considerando não só este cenário global, como as inadequações da compreensão hegemônica de ética na pesquisa – associada ao campo da saúde – e os esforços que vêm sendo feitos para que os resultados de pesquisas no campo respeitem exigências éticas outras e se adequem a princípios mais adequados ao campo.

This study provides a comprehensive characterization of various
hydrothermal sys-
tems in Southern Peru ranging from the faulted Precordillera’s steep
topography up to
the volcanic High Cordillera (>4000 m asl). The objective
is to investigate thermal anoma-
lies that may potentially serve as new geothermal resources.Our
integrated approach com-
bines: i) geochemistry from 14 hot springs sampled throughout the Tacna
region, and
ii) 3D numerical modeling of coupled groundwater and heat transfer
considering topog-
raphy and faults embedded in homogeneous permeability. Water and gas
analysis indi-
cates that the springs located near volcanoes discharge Na-K-Cl waters
with high tem-
peratures (>87°C), high Total Dissolved Solid
concentrations (TDS >3452 mg/L), and
free gases dominated by CO2 (>90 vol%). Springs located
along the regional faults in
the Precordillera discharge Ca-SO4 and Na-K-Cl waters with moderate
temperatures (27-
53°C), intermediate TDS concentrations (464-2458 mg/L), radiocarbon ages
between 1.4
and 7.9 kyr, and free gases dominated by N2 (>95 vol%).
The Aruma springs, which are
located at the transition between the High and the Precordillera,
display intermediate
characteristics. Numerical models accurately replicate the locations and
temperatures
of the fault-related springs only for permeable faults
(>10 m), revealing
the creation
of 100-km long thermal plumes along faults, locally rising up the
150°C-isotherm to about
∼ 1000 m below the surface. This approach clearly distinguishes the
spring origins, which
are volcanic in High Cordillera and tectonic in Precordillera. Moreover,
we highlight that
steep topographic gradient and permeable reverse faults in the Andean
forearc may gen-
erate considerable thermal anomalies, opening perspectives for the
geothermal exploration.
