The Epics Reinterpreted: Highlighting Feminist Issues While Sustaining Deep Motif
This article explores revisionist works based on the Ramayana and Mahabharata twin epics and looks at the voices of female protagonists. The main emphasis has been on the way that authoritative texts are utilized to create cultural hegemony on purpose for a particular impact. The article also highlights the power of stories and demonstrates how the textual politics in the retelling is directed towards achieving different outlines, especially the modern ideals of liberty, equality, and individuality. By providing a thorough study of the social and psychological struggles of epic women, the view also strikes at the fact that women encounter similar issues for generations. The review explores how Indian society’s patriarchal framework and social construction mistreated the epic heroines and how these elements still have an adverse effect on women in the present era. Their resistance patterns are used to classify and organize them
Monte Carlo study on anomalous carrier diffusion in inhomogeneous semiconductors
We perform ensemble Monte Carlo simulations of electron diffusion in high mobility inhomogeneous InAs layers. Electrons move ballistically for short times while moving diffusively for sufficiently long times. We find that electrons show anomalous diffusion in the intermediate time domain. Our study suggests that electrons in inhomogeneous InAs could be used to experimentally explore generalized random walk phenomena, which, some studies assert, also occur naturally in the motion of animal foraging paths
Soil Structure Interaction of Framed Structure Supported on Non- Homogeneity of Soil Condition
Soil often exhibits non – homogeneity, due to this non – homogeneity, different settlement occurs. This cause changes in the moments and forces in the members of superstructure frames. The order of magnitude of these changes is not known. In this paper, plane frames with differential configuration have been analysed taking into account soil- structure interaction using Finite Element Method. For the present study soil having different stiffnesses in the right and left half below the structure is considered and the effect of this non – homogeneity on superstructure forces having presented, for plane frames with number of bays varying from 3,5,7 and number of storeys 1to 6. The young’s modulus ratio of soil for right and left half has been varied from 1 to 7.5. To non – homogeneity of soil increases the forces in peripheral columns and beams, which were found to be already critical even for homogeneity soil condition. Hence, in general, it is concluded at non – homogeneity of soil increases the effect of soil interaction on the super structure forces
Protective responses of antioxidant enzymes against bisphenol-A induced oxidative stress in Asian Seabass Lates calcarifer
1458-1463Bisphenol A (BPA) is an endocrine disruptor used as plastic monomer and plasticizer widely present in the aquatic environment. In the present study, the effect of BPA on the antioxidant system in Lates calcarifer was documented. Three different concentrations such as 1, 10, 100 µg/l were selected and exposed to fishes for 30 days. After BPA exposure, antioxidant parameters were estimated against control. The levels of marker enzymes were assessed in the gill, muscle, liver and brain tissues. The results showed that the activities of superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx) and lipid peroxidation (LPx) were increased in treated groups than control. On the other hand, reduced glutathione (GSH) level was decreased in BPA exposed groups compared to control. Based on the results, imbalance in the antioxidant defence system clearly indicated that the BPA toxicity could lead to susceptible oxidative stress in various tissues of the fish L. calcarifer
Network of Earthquakes and Recurrences Therein
We quantify the correlation between earthquakes and use the same to
distinguish between relevant causally connected earthquakes. Our correlation
metric is a variation on the one introduced by Baiesi and Paczuski (2004). A
network of earthquakes is constructed, which is time ordered and with links
between the more correlated ones. Data pertaining to the California region has
been used in the study. Recurrences to earthquakes are identified employing
correlation thresholds to demarcate the most meaningful ones in each cluster.
The distribution of recurrence lengths and recurrence times are analyzed
subsequently to extract information about the complex dynamics. We find that
the unimodal feature of recurrence lengths helps to associate typical rupture
lengths with different magnitude earthquakes. The out-degree of the network
shows a hub structure rooted on the large magnitude earthquakes. In-degree
distribution is seen to be dependent on the density of events in the
neighborhood. Power laws are also obtained with recurrence time distribution
agreeing with the Omori law.Comment: 17 pages, 5 figure
Topical clobetasol propionate 0.025%: a therapeutic dermatologic asset
Over several decades, topical corticosteroids (TCs) have been used in the treatment of various dermatoses such as psoriasis, contact dermatitis, and eczema, among others. The TCs act by reducing inflammation and irritation after topical application. The therapeutic effect of TCs is bestowed through their diverse biologic properties such as anti-inflammatory, antiproliferative, vasoconstrictive, and antimitotic activity, and its role in the reduction of lymphocyte reactivity, modulation of Langerhans cell expression, cellular and lysosomal membrane stabilization, reduction of recruitment of neutrophils and monocytes, reduction of mast cell density and reactivity, and sensitization of immunoglobulin E. Clobetasol propionate (CP) 0.025% is a class I TC available as a cream formulation. The cream formulation contains half the concentration of conventional CP (0.025%), without the loss of therapeutic potency. The lack of additives such as penetration enhancers (propylene glycol) further prevents cutaneous microbiome alteration. This comprehensive case series covers the potent efficacy and safety of ImpoyzTM (CP) Cream 0.025% in the management of various dermatological disorders
OBSERVATIONS OF SEISMO-IONOSPHERIC PERTURBATIONS USING WAVELET ANALYSIS
Electromagnetic signals generated before and during the Earthquakes lie in a broad range of frequencies from MHz to Qasi DC frequencies (Darcy Karakelian et.,al 20001). These signals reach higher altitudes and perturb the background atmosphere by dumping their energy (V.V. Hegai et.,al 20062 , Tadahiko Ogawa et.,al 20123). These electromagnetic signals cause perturbations in the ion content of the ionosphere. The study of these perturbations is important to understand their evolution mechanisms. The ionospheric variability is measured in terms of ionospheric Total Electron content (TEC). The complex time varying and non-linear characteristics of Seismo-ionospheric perturbations are different from other disturbances ( Li-ming He et.,al, 20114). The earthquake which occurred in Indonesian region on 1st Sepember 2013 with a magnitude M>6 is considered for the present study. The time frequency analysis of narrow transition regions of these signals are analyzed using Wavelets ( Gwal A.K., et., al 2025, Michael E. Contadakis et.,al 20126) . Analysis of the non-stationary data using wavelets provides time localized alternatives and complex wavelets are useful in accurate detection and recognition of transient signals. The results show that these perturbations are observed three days before the Earthquake and are increasing in nature. The observed periodicities on the Earthquake day may represent that there is possible transfer of momentum and energy from lower atmosphere to upper atmosphere
Secretion of Clostridium difficile Toxins A and B Requires the Holin-like Protein TcdE
The pathogenesis of Clostridium difficile, the major cause of antibiotic-associated diarrhea, is mainly associated with the production and activities of two major toxins. In many bacteria, toxins are released into the extracellular environment via the general secretion pathways. C. difficile toxins A and B have no export signature and their secretion is not explainable by cell lysis, suggesting that they might be secreted by an unusual mechanism. The TcdE protein encoded within the C. difficile pathogenicity locus (PaLoc) has predicted structural features similar to those of bacteriophage holin proteins. During many types of phage infection, host lysis is driven by an endolysin that crosses the cytoplasmic membrane through a pore formed by holin oligomerization. We demonstrated that TcdE has a holin-like activity by functionally complementing a λ phage deprived of its holin. Similar to λ holin, TcdE expressed in Escherichia coli and C. difficile formed oligomers in the cytoplamic membrane. A C. difficile tcdE mutant strain grew at the same rate as the wild-type strain, but accumulated a dramatically reduced amount of toxin proteins in the medium. However, the complemented tcdE mutant released the toxins efficiently. There was no difference in the abundance of tcdA and tcdB transcripts or of several cytoplasmic proteins in the mutant and the wild-type strains. In addition, TcdE did not overtly affect membrane integrity of C. difficile in the presence of TcdA/TcdB. Thus, TcdE acts as a holin-like protein to facilitate the release of C. difficile toxins to the extracellular environment, but, unlike the phage holins, does not cause the non-specific release of cytosolic contents. TcdE appears to be the first example of a bacterial protein that releases toxins into the environment by a phage-like system
Delivering the Thinking Healthy Programme for perinatal depression through peers: an individually randomised controlled trial in India
Background The Thinking Healthy Programme (THP) is a psychological intervention recommended for the treatment of perinatal depression. However, efforts to integrate the intervention at scale into the routines of community health workers who delivered the THP when it was first evaluated were compromised by the competing responsibilities of community health workers. We aimed to assess the effectiveness and cost-effectiveness of THP peer-delivered (THPP) in Goa, India. Methods In this single-blind, individually randomised controlled trial, we recruited pregnant women aged 18 years or older who scored at least 10 on the Patient Health Questionnaire-9 (PHQ-9) from antenatal clinics in Goa. Participants were randomly allocated (1:1) to receive enhanced usual care (EUC; so-called because, in India, perinatal depression is not typically treated) only (control group) or THPP in addition to EUC (intervention group) in randomly sized blocks that were stratified by area of residence (urban or rural). Group allocations were concealed from participants and researchers before assignments were made by use of sequentially numbered opaque envelopes. The primary outcomes were the severity of depressive symptoms (assessed by PHQ-9 score) and the prevalence of remission (defined as a PHQ-9 score of less than 5) in participants with available data 6 months after childbirth, which was assessed by researchers who were masked to treatment allocations. We analysed outcomes by intention to treat, adjusting for covariates that were defined a priori or that showed imbalance at baseline. The trial is registered with ClinicalTrials.gov, number NCT02104232. Findings Between Oct 24, 2014, and June 24, 2016, we assessed 118 260 women for their eligibility for screening, of whom 111 851 (94·6%) women were ineligible. 6409 (5·4%) women were eligible for screening and 6369 (99·4%) of these women consented to be screened with the PHQ-9 (40 women did not consent), of whom 333 (5·2%) screened positive for depression (defined as a PHQ-9 score of at least 10). We enrolled 280 (84·1%) women with perinatal depression; 140 women were assigned to the THPP and EUC group and 140 women to the EUC only group. The final treatment was given on May 27, 2017. The final 6-month outcome assessment was completed on June 9, 2017. At 6 months after birth, 122 (87%) women in the THPP and EUC group and 129 (92%) women in the EUC only group were assessed for the primary outcome. There was a higher prevalence of remission at 6 months after birth in the THPP and EUC group compared with the EUC only group (89 [73%] women in the intervention group vs 77 [60%] women in the control group; prevalence ratio 1·21, 95% CI 1·01 to 1·45; p=0·04), but there was no evidence of a difference in symptom severity between the groups (mean PHQ-9 score 3·47 [SD 4·49] in the intervention group vs 4·48 [5·11] in the control group; standardised mean difference −0·18, 95% CI −0·43 to 0·07; p=0·16). There was no evidence of significant differences in serious adverse events between the groups. Interpretation THPP had a moderate effect on remission from perinatal depression over the 6-month postnatal period. THPP is relatively cheap to deliver and is cost-saving through reduced health-care, time and productivity costs
