The Persistence of Gender-blind Phenomena in Indian Science Academia
Using the theoretical tool of gender-blind sexism, an extension of Bonilla Silva’s (2003) color-blind racism, the current study explores the key determinants which are responsible for discrimination of women in science disciplines in Indian higher education. We argue that gender-blind sexism demonstrates how gender discrimination operates as institutional tools to discriminate between men and women in science fields. Although the science stream proclaims gender neutrality/blindness, it ultimately disfavors women over men. This study with the aid of extensive in-depth face-to-face interviews, aims to recognize the pattern accountable for women’s reduced progress in the sciences. Against the backdrop of the recently framed National Education Policy (NEP) 2020, by the Government of India, this intensive qualitative study identifies certain crucial dimensions responsible for gender discrimination and diminishing participation of females in Indian academia, especially in the sciences. With several institutional policies that have been in place to mitigate challenges in overt sexist patterns in the workplace, the analysis still confirms the existence of a perceivable organizational barrier, which hinders the rise of women faculty members. We infer that gender discrimination operates through covert mechanisms of gender-blindness and such practices are normalized institutionally as a brand-new form of sexism
Benign Recurrent Intrahepatic Cholestasis in Pregnancy: Fetal Death at 36 Weeks of Gestation
Introduction: Benign recurrent intrahepatic cholestasis is a rare hepatologic disorder characterized by recurrent, self-limited episodes of severe pruritus, jaundice, and elevated bile acids. While there are guidelines for the management of intrahepatic cholestasis of pregnancy, the literature regarding benign recurrent intrahepatic cholestasis and pregnancy is limited.
Case: A 29-year-old G1P0 woman, with history of liver toxicity, had elevated total serum bile acid levels and liver enzymes documented at 8 weeks of gestation and throughout her pregnancy. She had a reactive nonstress test just 3 days prior to her induction. Fetal demise was noted when she presented at 36 weeks for her induction.
Conclusion: We recommend that women with elevated total serum bile acid early in pregnancy due to a separate entity relative to intrahepatic cholestasis of pregnancy be managed in a more individualized approach
New Discrete Logarithm Computation for the Medium Prime Case Using the Function Field Sieve
International audienceThe present work reports progress in discrete logarithm computation for the general medium prime case using the function field sieve algorithm. A new record discrete logarithm computation over a 1051-bit field having a 22-bit characteristic was performed. This computation builds on and implements previously known techniques. Analysis indicates that the relation collection and descent steps are within reach for fields with 32-bit characteristic and moderate extension degrees. It is the linear algebra step which will dominate the computation time for any discrete logarithm computation over such fields
Synthetic Observations with the Square Kilometre Array (SKA) -- development towards an end-to-end pipeline
Detection of the redshifted 21-cm signal of neutral hydrogen from the Cosmic
Dawn and the Epoch of Reionization is one of the final frontiers of modern
observational cosmology. The inherently faint signal makes it susceptible to
contamination by several sources like astrophysical foregrounds and
instrumental systematics. Nevertheless, developments achieved in the recent
times will combine to make signal detection possible with the upcoming Square
Kilometer Array (SKA), both statistically and via tomography. This review
describes an indigenously developed end-to-end pipeline that simulates
sensitive interferometric observations. It mainly focuses on the requirements
for \hi detection in interferometers. In its present form, it can mimic the
effects of realistic point source foregrounds and systematics- calibration
error and position error on 21-cm observations. The performance of the pipeline
is demonstrated for test cases with 0.01\% calibration error and position
error. Its performance is consistent across telescope, foreground, and signal
models. The focus of the simulation pipeline during the initial stages was for
EoR science. But since this is a general interferometric simulation pipeline,
it will be helpful to the entire SKA user community, irrespective of the
science goals.Comment: 24 Pages, 7 Figures, Review Article to appear in Special Issue of

Novel Microbial System Developed from Low-Level Radioactive Waste Treatment Plant for Environmental Sustenance
A packed bed bioreactor efficiently treated low-level radioactive waste for years with a retention time of 24 h using acetate as the sole carbon source. However, there was generation of dead biomass. This bioreactor biomass was used to develop a bacterial consortium, which could perform the function within 4 h while simultaneously accumulating nitrate and phosphate. The dead mass was negligible. Serial dilution technique was used to isolate the world’s first pure culture of a nitrate accumulating strain from this consortium. This isolate could simultaneously accumulate nitrate and phosphate from solution. Its ability to form biofilm helped develop a packed bed bioreactor system for waste water treatment, which could optimally remove 94.46% nitrate within 11 h in batch mode while 8 h in continuous mode from waste water starting from 275 ppm of nitrate. The conventional approach revealed the strain to be a member of genus Bacillus but showed distinct differences with the type strains. Further insilico analysis of the draft genome and the putative protein sequences using the bioinformatics tools revealed the strain to be a novel variant of genus Bacillus. The sequestered nitrate and phosphate within the cell were visualized through electron microscopy and explained the reason behind the ability of the isolate to accumulate 1.12 mg of phosphate and 1.3 gm of nitrate per gram of wet weight. Transcriptome analysis proposed the mechanism behind the accumulation of nitrate and phosphate in case of this novel bacterial isolate (MCC 0008). The strain with the sequestered nutrients work as biofertilizer for yield enhancement in case of mung bean while maintaining soil fertility post-cultivation
COVID-19 is associated with early emergence of preeclampsia: results from a large regional collaborative
Objective: To examine the relationship between COVID-19 and preeclampsia (PreE) in a large, diverse population.
Study Design: The COVID-19 in Pregnancy and The Newborn: State of Michigan Collaborative established a database of pregnant patients admitted to 14 institutions in Southern Michigan. Patients with COVID-19 (cases) were matched to 2 or 3 non-COVID patients (controls) on the same unit within 30 days of each case. Relative Risks (RR) were calculated using robust Poisson regression models with adjustment for covariates. Chi-squared test for trend was used to assess the increase in risk with the severity of disease.
Results: 369 cases and 1,090 controls were delivered between March - October 2020. An increased risk of PreE (RR=1.8), driven almost entirely by an increase in preterm PreE (pretermPreE) (RR=2.85) was observed in COVID pregnancies (Table 1), with a dose-response relationship with symptomatology and severity (Table 2). The associations between COVID-19 disease and PreE or pretermPreE were independent of other risk factors, as demonstrated by the minimal changes in RR after adjustment for confounders (Table 1). However, African American (AA) COVID patients experienced pretermPreE 1.9 times more than COVID patients of other races (10.1 vs 5.3), an increase not observed in control patients. The strength of the association for COVID with PreE was comparable to the association of PreE with chronic hypertension and nulliparity (data not shown). Increasing symptoms and severity of COVID-19 were associated with an increased risk for PreE with placental lesions, even after adjustment for relevant covariates (Tables 1 & 2). Non-PreE COVID patients had an increased trend of placental lesions compared to non-COVID patients, reaching significance for intravillous thrombin.
Conclusion: COVID-19 is significantly associated with early emergence of PreE, independent of known risk factors other than AA race. Our study shows that among patients predisposed to PreE, COVID-19 impacts PreE severity in that it leads to pretermPreE. Further studies on COVID-19 and PreE, with a focus on racial disparities, is warranted
