Abstract

The deterioration of cadmium yellow paints in artworks by Joan Miró (1893–1983) and from painting materials from his studios in Mallorca (Spain) was investigated for the first time. Artworks showed discolouration and chalking of paints containing cadmium yellow, altering the colour balance of the works. Analysis of samples from these artworks and from tube paints and palettes containing degraded and non-degraded cadmium yellow paints showed that degraded paints are composed of poorly crystalline CdS/Cd1 − xZnxS with a low percentage of Zn in an oil binding medium. Cadmium sulfates were identified as the main deterioration products and their distribution in the paint layers was mapped using SR µXANES and µXRD techniques. Time-resolved photoluminescence measurements demonstrated that highly degraded samples display a peculiar pink/orange emission with microsecond lifetime. In agreement with recent studies on altered cadmium paints, these evidences suggest that the cause of the chemical change of the paint should be related with its manufacturing method, which affects the degree of crystallinity of the resulting pigment and includes the presence of zinc, besides the environmental conditions in which artworks have been exposed. Finally, it is worth noting that the degraded paints in the analysed Miró artworks have a chemical composition very similar to the one of the paint in the tube Cadmium Yellow Lemon No. 1 by Lucien Lefebvre-Foinet. Indeed, paint tubes of this brand were found in the studio, linking the use of this product with Miro’s degraded artworks.

Published: March 2023

Abstract

Star like structural compounds were synthesized from different moles % of either dodecyl acrylate or triethylenetetramine using a one-pot commercial synthesis technique. The polymers that were created had various terminations. Fourier Transform Infrared (FTIR) spectroscopy and 1HNMR were used to verify the produced polymers' chemical composition with different terminations. Furthermore, by analysis of Dynamic Light Scattering (DLS), the size and distribution of the synthesised branched polymers were evaluated. Using a Gel-permeation chromatograph, the modified hyperbranched polymer's molecular weight synthesized with various end points were assessed. The unorganized structured prepared compounds with various molar feed ratios dodecyl acrylate: triethylenetetramine (DDA: TETA) was designed as A, B, C, D and E. Moreover, the synthesized compounds expressed as viscosity index improver (VII); as the amount of combined additives in the mixture is concentrated in the solution, so does the VI. As the percentage of triethylenetetramine in prepared hyperbranched polymers increases, so does the VI. and the most effective VI is (E) VI = 212. All of the synthesized hyperbranched polymers have Newtonian rheological behavior as their rheological behavior.

Abstract

Reducing mosquito abundance or interfering with its ability to support the parasite cycle can help to interrupt malaria in areas of significant risk of malaria transmission. Fluralaner is a safe and effective drug for veterinary use indicated for the treatment against fleas and ticks which acts as an antagonist of chloride ion channels mediated by γ-aminobutyric acid (GABA), preventing the entry of these ions into the postsynaptic neuron, leading to hyperexcitability of the postsynaptic neuron of the central nervous system of arthropods. Fluralaner demonstrated insecticidal activity against different species. The study aimed to evaluate the effects of Fluralaner on the biology, survival, and reproductive fitness of Anopheles aquasalis. The following Lethal Concentrations (LC) were determined for An. aquasalis: LC5 = 0.511 µM; LC25= 1.625 µM; LC50= 3.237. A significant decrease (P<0.001) was evident in the number of eggs, larvae, and pupae in the group exposed to a sublethal dose of Fluralaner when compared to a control group (without the drug). Using blood from dogs after administration of Fluralaner, it was observed that the drug causes 100% mortality in An. aquasalis in less than 24 hours after feeding; this effect remains even after 90 days in all samples. In the drug-free group, Fluralaner showed the same result for up to 60 days, and after that, there was a slight reduction in its effect, evidenced by a decrease in the percentage of dead females. However, still significant when compared to the control group (P<0.001). Fluralaner affects the biology and reduction of survival in An. aquasalis in a lasting and prolonged period, and its fecundity with lower dosages, is a strong candidate for controlling disease vectors.
Gender Pay Inequality: An Examination of the Lilly Ledbetter Fair Pay Act Six Years Later
Authors: Wade Michelle , Fiorentino Susan 
Published: March 2023

The Lilly Ledbetter Fair Pay Act was the first piece of legislation signed into law by President Barack Obama in January of 2009. This legislation enables an employee to sue more easily for wage discrimination under Title VII of the Civil Rights Act of 1964. In this article, we examine the impact that the Lilly Ledbetter Fair Pay Act has had on gender pay equity discrimination complaints and on how the lower courts have interpreted it since it was signed into law in January of 2009. First, we will provide a brief background about the passage of the Lilly Ledbetter Fair Pay Act and a description of the legislation itself. Then we will examine any changes in discrimination complaints since its passage, and we will analyze how lower courts have interpreted the legislation. We conclude by arguing that passage of the Lilly Ledbetter Fair Pay Act has offered little redress for gender wage discrimination since its passage six years ago.

Women in Computer Science and Engineering: A Transformational Leadership Approach to Gender Equity
Authors: Ryan Lindy , D­az Eduardo R , Grow Arron P. 
Published: March 2023

The underrepresentation of women in science, technology, engineering, and mathematics (STEM) is a phenomenon that needs to be addressed from an educational perspective. Within the domains of computer science and engineering (CS&E) the gender imbalance is even more acute as the underrepresentation of women not only persists but has increased over the past few decades (Corbett & Hill, 2015; Master et al., 2016). In this paper a discussion of the current situation of women’s underrepresentation across broad CS&E domains is presented. This will be demonstrated through a review of research into the historical factors and institutional practices that have been ongoing barriers to the inclusion of women in CS&E. Then, a discussion of how transformational leadership theory can serve as a tool for change to help scholars better understand the present situation, and then guide practitioners in overcoming it, is presented. To this end, the paper concludes with a discussion of how diversity and inclusion ideas, based on a transformational leadership approach, can improve gender equity in CS&E.

Published: March 2023

With the persistence of women's limited advancement into senior leadership, organizations have employed an arsenal of diversity, equity, and inclusion strategies such as implicit bias training, intentional mentoring, and efforts to authentically support work-life policies. Male allyship has emerged as a recent strategy aimed at gender equity. The asymmetric power between advantaged and disadvantages groups is central to the concept of allyship in studies across disciplines, such as sociology, social justice and economics. Management scholars have identified power, specifically the requisite sharing of or fear of diminishment of, as a barrier to men participating in gender equity initiatives to advance women. To examine how organizations might address the power inherent in the male ally role, we employ the Bolman and Deal Four Frames Organizational Model. We propose that while male ally programs reside in the Human Resources Frame, the success of that strategy depends on managing the Political Frame. In promoting gender equity, organizations are seeking to distribute power more broadly to enable both men and women to fully contribute. By considering organizational politics, the competition for scarce resources, power and influence, we argue that practitioners will benefit from a realistic assessment of the role that power plays in both hindering and advancing male ally endeavors. We draw on the literature, survey data, and ongoing work with men and women engaged in male ally initiatives, and use the Bolman and Deal model to make recommendations for practitioners, male allies, and women in using power while building gender-equitable organizations.
Career Trajectories of Women Faculty Who Became Academic Administrators
Authors: Vancour Michele L. 
Published: March 2023

Women faculty often view academic leadership as incompatible with their work-life balance, detracting from research and teaching commitments, resulting in a loss of autonomy and an abandonment of discipline, promoting change in their relationships with colleagues, and placing an increased emphasis on budgeting, regulations and compliance (DeZure et al., 2014). Many researchers suggest that institutional culture works against leadership development for faculty, making the transition from faculty to administrator unlikely (Barden & Curry, 2013). It is increasingly important to identify the key factors that make the difference for women faculty to assume these roles. As such, in this study qualitative methods were employed to examine the experiences and career trajectories of 16 academic women who held tenured, fully promoted faculty positions prior to becoming administrators. The researcher found evidence to support future recruitment and retention in higher education leadership.
Effect of different MIT rainfall event division methods on volume capture ratio of annual rainfall based on bioretention assessment

Published: March 2023

Abstract
Volume capture ratio of annual rainfall (VCRAR) is the key parameter of low-impact development (LID) facilities design, which is significantly affected by the rainfall event division method. However, there is no universal agreement on how to determine an optimal division method to achieve it. A modified minimum inter-event time (MIT) method based on MATLAB software was proposed to find an optimal MIT value. The result showed that the optimal MIT value in Beijing is 200 min based on the daily rainfall data from 1987 to 2016, and the annual average rainfall events were 34.2 with an average rainfall depth of 13.7 mm. Taking bioretention facilities as an example, the errors of design VCRAR under different MIT values were compared based on a Stormwater Management Model (SWMM). The results showed that when design VCRAR was ≤50, 55–60, 60–75, 75–80 and &gt;80%, the optimal MIT value for LID facilities design was 60, 120, 200, 360 and 1,440 min, respectively. Therefore, the optimal MIT should be flexibly selected with the changing of design VCRAR, to ensure that LID facilities meet the design goals.
Aportes al estudio de las redes hidrosociales desde los métodos de análisis de redes sociales ARS
Authors: Trujillo-Osorio Catalina , Peña-Varón Miguel , Revelo-Osorio Lina 
Published: March 2023

El análisis de redes sociales (ARS) es una herramienta metodológica transdisciplinar ampliamente utilizada para comprender las estructuras de relaciones entre los actores involucrados en la gobernanza territorial de los recursos naturales. Dada la complejidad del conjunto de actores involucrados en la gobernanza territorial del agua que se da a nivel de cuencas hidrográficas, este artículo propone el ARS como una herramienta pertinente para comprender las redes de actores que se configuran alrededor del uso, control y cuidado del agua, integrando actores en diversos niveles sociales, administrativos y territoriales. Para ello se propone una metodología participativa e incluyente que permite la identificación y reconocimiento de los actores que inciden en el uso del agua, y participan de la gobernanza de la cuenca de manera directa e indirecta. A partir de esta metodología se recopiló información sobre relaciones entre actores del agua, se construyó una matriz relacional y se aplicaron métricas de ARS para analizar la estructura de la red de actores en la Cuenca alta del Río Meléndez- CARM, en Colombia. La metodología permite mostrar los actores del agua como una red hidrosocial, analizar sus características estructurales, identificar los actores más centrales y con diversa participación e importancia en las redes de gobernanza, e identificar los actores que participan del cuidado del agua, y que son claves para mejorar la capacidad de gobernanza y la seguridad hídrica de la CARM.
Electronic Cigarettes Versus Tobacco Poly Use: Reduced Oxidative Stress but
Similar Inflammatory Effect
Authors: Al-Najar Ajwan Abdulmonem Hubail , Tabassum Tanzima , Thaliffdeen Fathima Leila , Kadhum Safa Jawad , Karanghadan Abid Shaheer , Khan Nelofar Sami 
Published: March 2023

Background:
Smoking in any form is a significant risk factor for developing cardiovascular diseases, chronic obstructive pulmonary disease, lung cancer, and other oxidative damage-induced diseases. The increasing global trend of E-cigarettes has led traditional smokers to perceive them as a safer option.

Objectives:
This study aimed to compare the levels of malondialdehyde (MDA) as a marker of oxidative damage and high-sensitivity C-reactive protein (hs-CRP) as a marker of inflammation between pure E-cigarette users and tobacco poly-users (smoking combinations of traditional products). Moreover, it also evaluated the influence of Body Mass Index, frequency, and duration of vaping/smoking on these biomarkers.

Materials and Methods:
This analytical cross-sectional pilot study included 40 males aged 18-25 (20 pure E-cigarette users and 20 tobacco poly-users). MDA and hs-CRP were estimated on serum, and SPSS-Version 28.0.1.1 was used for data analysis. Mean hs-CRP and MDA levels for the two groups were compared using the Mann-Whitney-U test.

Results:
Mean level of hs-CRP between the two groups was not significantly different. However, MDA levels were lower in pure E-cigarette users than in tobacco poly-users, especially among those with normal BMI and those who vaped/smoked more frequently and for a longer duration

Conclusion:
Oxidative damage was lesser for pure E-cigarette users and could potentially be the less harmful option than tobacco poly-use. However, E-cigarettes are not the safest substitute for conventional smoking as it causes a similar extent of risk for inflammation-related CVD. Findings need further exploration to study the long-term effects on a larger population group to draw definitive conclusions.
(R)-9bMS Inhibited the Protein Synthesis and Autophagy of Triple
Negative Breast Cancer Cells via Regulating miR-4660/mTOR Axis
Authors: Bai Xiangdong , Han Guohui , Li Feng , Li Weina , Bu Peng , Zhang Huanhu , Xie Jun 
Published: March 2023

Background:
Unlike other subtypes of breast cancer, triple negative breast cancer (TNBC)
exhibits aggressive and metastatic behaviors and a lack of effective targeted therapeutics. (R)-9bMS, a
small-molecule inhibitor of the non-receptor tyrosine kinase 2 (TNK2), significantly inhibited TNBC
cell growth; however, the functional mechanism of (R)-9bMS in TNBC remains largely unknown.

Objective:
To explore the functional mechanism of (R)-9bMS in TNBC.

Methods:
Cell proliferation, apoptosis and xenograft tumor growth assays were performed to evaluate
the effects of (R)-9bMS on TNBC. The expression levels of miRNA and protein were detected by RTqPCR
or western blot, respectively. Protein synthesis was determined by analyzing the polysome
profile and 35S-met incorporation.

Results:
(R)-9bMS attenuated TNBC cell proliferation, induced cell apoptosis, and inhibited xenograft
tumor growth. Mechanism study indicated that (R)-9bMS upregulated the expression of miR-4660 in
TNBC cells. The expression of miR-4660 is lower in TNBC samples than that of the non-cancerous
tissues. miR-4660 overexpression inhibited TNBC cell proliferation by targeting the mammalian target
of rapamycin (mTOR), which reduced mTOR abundance in TNBC cells. Consistent with the downregulation
of mTOR, exposure of (R)-9bMS inhibited the phosphorylation of p70S6K and 4E-BP1,
which consequently interrupted the total protein synthesis and autophagy of TNBC cells.

Conclusion:
These findings uncovered the novel working mechanism of (R)-9bMS in TNBC by
attenuating mTOR signaling via up-regulating miR-4660. The potential clinical significance of (R)-
9bMS in TNBC treatment is interesting to explore.

Abstract:This review covers the lithium effects on microorganisms, including gut and soil bacteria. Available studies of the biological effects of lithium salts have revealed a wide range of different effects of lithium cations on various microorganisms, but so far, the study of this direction has not been summarized enough. Here we consider the confirmed and various plausible mechanisms of lithium action on microorganisms. Special emphasis is placed on assessing the effect of lithium ions under oxidative stress and adverse environmental conditions. The impact of lithium on the human microbiome is also being reviewed and discussed. Controversial effects of lithium have been shown, including the inhibitory and stimulating effects of lithium on bacterial growth.

Published: March 2023

Objective:
This study aimed to evaluate the possible effects of chlorpyrifos on the rat
hippocampus and evaluate whether these effects can be decreased with chrysin co-administration in an
animal model.

Methods:
Male Wistar rats were randomly divided into 5 groups; Control (C), Chlorpyrifos (CPF),
Chlorpyrifos + Chrysin (12.5mg/kg) (CPF + CH1), Chlorpyrifos + Chrysin (25mg/kg) (CPF + CH2),
Chlorpyrifos + Chrysin (50 mg/kg) (CPF + CH3). After 45 days, hippocampus tissues were evaluated
by biochemical and histopathological tests.

Results:
Biochemical findings indicated that CPF and CPF plus CH administration could not
significantly change SOD activity, and MAD, GSH, and NO levels in the hippocampus tissue of
animals versus controls. Histopathological findings of the toxic effects of CPF on hippocampus tissue
as evidenced by inflammatory cell infiltration, degeneration/necrosis, and mild hyperemia. CH could
ameliorate these histopathological changes in a dose-dependent manner.

Conclusion:
In conclusion, CH was effective against histopathological damage induced by CPF in the
hippocampus through modulating inflammation and apoptosis.
Minimal Contribution of the Social Determinants of Health to the Prevalence
of Hypertension among Egyptian Public Servants
Authors: Eshak Ehab Salah , Kamal Nashwa Nabil , Kamal Nashaat Nabil 
Published: March 2023

Background:
Previous research suggests the role of social determinants of health (SDH) in the prevalence of hypertension.

Objective:
The study aimed to estimate the contribution of SDH to the prevalence of hypertension.

Methods:
We recruited 3072 Egyptian public servants who answered a self-administered ques-tionnaire, including hypertension history. We measured the participants’ blood pressure with standardized procedures. The logistic regression models were used to assess the associations be-tween SDH and hypertension

Results:
The prevalence of hypertension was 28.2% (34.2% in males and 22.5% in females). The prevalence of undiagnosed hypertension was 16.3% (23.9% and 9.2%, respectively); thus, 57.8% of the hypertensive subjects were unaware of their high blood pressure status. SDH were associat-ed with the odds of having hypertension in the unadjusted analyses. Higher education, being sin-gle, and having minor family members were associated with low odds of hypertension. On the other hand, non-professional occupations, job hours, household income, total family members, and work-family conflicts were associated with higher odds of hypertension. However, in the multivar-iable analyses, which included all SDH and adjusted for age, gender, smoking, physical activity, body mass index, medical history of chronic diseases, and family history of hypertension, only job hours were associated with the odds of having hypertension and undiagnosed hypertension: odds ratio (95% CI) = 1.07 (1.01-1.14) and 1.11 (1.02-1.20), respectively.

Conclusion:
SDH contributed minimally to the odds of having hypertension among public offi-cials in Minia, Egypt. Civil servants with long working hours should be tracked with regular blood pressure monitoring as a high-risk group for hypertension
