Isospin effects in the disappearance of flow as a function of colliding geometry

We study the effect of isospin degree of freedom on the balance energy (E$_{bal}$) as well as its mass dependence throughout the mass range 48-270 for two sets of isobaric systems with N/Z = 1 and 1.4 at different colliding geometries ranging from central to peripheral ones. Our findings reveal the dominance of Coulomb repulsion in isospin effects on E$_{bal}$ as well as its mass dependence throughout the range of the colliding geometry. Our results also indicate that the effect of symmetry energy and nucleon-nucleon cross section on E$_{bal}$ is uniform throughout the mass range and throughout the colliding geometry. We also present the counter balancing of nucleon-nucleon collisions and mean field by reducing the Coulomb and the counter balancing of Coulomb and mean filed by removing the nucleon-nucleon collisions.Comment: 15 pages, 5 figure

Sensitivity of the transverse flow towards symmetry energy

We study the sensitivity of transverse flow towards symmetry energy in the Fermi energy region as well as at high energies. We find that transverse flow is sensitive to symmetry energy as well as its density dependence in the Fermi energy region. We also show that the transverse flow can address the symmetry energy at densities about twice the saturation density, however it shows the insensitivity towards the symmetry energy at densities $\rho/\rho_{0}$ $>$ 2. The mechanism for the sensitivity of transverse flow towards symmetry energy as well as its density dependence is also discussed.Comment: Phys. Rev. C (in press)2011 14 pages, 6 figure

Prevalence of ecosapentaenoic acid and docosahexaenoic acid deficiency in pregnant women: a prospective observational study

Background: Docosahexaenoic acid (DHA), ecosapentaenoic acid (EPA) and alpha lineoloic acid (α-LA) are essential fatty acids of the long chain polyunsaturated fatty acid (LC-PUFA) or omega-3 fatty acid. These fatty acids are not synthesized by our body. Diets rich in LC-PUFA reduces the incidence of - preeclampsia, intrauterine growth restriction, preterm delivery, in utero fetal death and placental abruption. Objectives of the study were: to estimate the prevalence of EPA and DHA deficiency in pregnant women by omega-3 index test (O3I), and also to correlate blood levels of EPA and DHA with various socio demographic parameters. Methods: All enrolled subjects were assessed with a pre-defined performa for their demographic and socio-economic characteristics, personal history, obstetric history, body mass index (BMI), education, diet and blood samples were tested for O3I. Results: Result of the study indicated that 98% of pregnant women had EPA and DHA deficiency as indicated by O3I levels. This was regardless of age, parity, BMI, and socio economic status. Women consuming vegetarian diet had statistically significant lower mean and median levels of O3I as compared to the women having a non-vegetarian diet, p value <0.001, 0.004 respectively. In our entire cohort of 150 women, only 2 non-vegetarian women had sufficient O3I. Conclusions: 98% of pregnant women across various socio economic classes had EPA and DHA deficiency as measured by O3I levels. Vegetarians had statistically significant lower levels of O3I as compared to the non-vegetarians

Bioremediation of Chlorpyrifos Contaminated Soil by Microorganism

India is agricultural based country where 70% of the population survives on it. In order to increase the production of field various pesticides are used. Chlorpyrifos (O,O-diethyl O-3,5,6-trichloro-2-pyridyl phosphorothioate) is an organophosphate pesticide which is widely used as insecticide for crop protection. But due to its persistent nature into the environment, it is leading to various hazards including neurotoxic effects, cardiovascular diseases and respiratory diseases. Bioremediation is a technology to eliminate chlorpyrifos efficiently from the environment. In bioremediation of chlorpyrifos the potential degradative microorganisms possess opd (organophosphate degrading) gene which hydrolyses the chlorpyrifos and utilizes it as a sole carbon source.Thus the present review discusses about how through bioremediation the pesticide chlorpyrifos can be degraded using potential soil microorganisms

Recent progress in the CoCrNi alloy system

The exceptional mechanical properties, particularly at cryogenic temperatures, of the equiatomic CoCrNi alloy are documented in numerous published studies. Similar to the equiatomic CoCrFeMnNi (so called Cantor alloy), from which the ternary alloy was derived, the CoCrNi ternary possesses low stacking fault energy that promotes complex deformation modes, as well as the activation of deformation twinning at ambient temperatures and increased strain. In addition to outstanding deformation mechanisms, chemical short-range order and face-centered cubic (FCC)-hexagonal close packed (HCP) transitions have been verified in this alloy and prove to be key factors contributing to the alloy\u27s notable properties. The relationship between stacking fault energy and FCC→HCP phase transitions has been developed over the years through other low stacking fault materials, but the question that arises is: do well established physical metallurgical mechanisms require modification when applied to systems such as CoCrNi given their compositional complexity? Local chemical order plays an important role in that it brings the deviation from the random solid solution behavior generally expected from complex concentrated alloys. In this review, the fundamental atomistic deformation mechanisms of the CoCrNi alloy will be reviewed with a focus on deformation substructures and chemical short-range ordering. Recent studies on microstructural engineering through thermo-mechanical processing and efforts to enhance the tensile properties of the CoCrNi derived systems with minor alloying additions are discussed. Finally, future directions of research, which involve applying current understanding of the underlying mechanisms towards alloy design strategies, are discussed

Isospin effects on the energy of vanishing flow in heavy-ion collisions

Using the isospin-dependent quantum molecular dynamics model we study the isospin effects on the disappearance of flow for the reactions of $^{58}Ni$ + $^{58}Ni$ and $^{58}Fe$ +$^{58}Fe$ as a function of impact parameter. We found good agreement between our calculations and experimentally measured energy of vanishing flow at all colliding geometries. Our calculations reproduce the experimental data within 5%(10%) at central (peripheral) geometries

Graduate Medical Education on the Frontlines during the COVID-19 Pandemic in New York City- A Response to Promote Well-being

Introduction: The COVID-19 pandemic has driven many health care institutions in the United States beyond their capacity. Physicians-in-training in graduate medical education programs have suffered the strain of providing patient care during this unprecedented time of crisis. The significant prevalence of pre-existing resident and fellow burnout and depression makes the need for action by institutions to support the well-being of residents and fellows even more urgent. We aim to describe innovative adaptations our Office of Graduate Medical Education implemented with the support of institutional leadership as responses to promote the well-being of residents and fellows on the frontlines during the COVID-19 pandemic. Methods: The Office of Graduate Medical Education (GME), in collaboration with the Office of Well-being and Resilience, developed a set of resources and interventions to support trainees during the pandemic based on four major categories: workplace culture, personal factors and health, mental health support, and workplace efficiency and function. Examination of the capacity of existing services and gaps that needed to be filled in the rapidly evolving early days of the COVID pandemic led to a robust growth in resources. For example, the already established Student and Trainee Mental Health program was able to expand and adapt its role to serve trainee needs more effectively. Results: We expanded resources to target trainee well-being across a broad array of domains within a short time frame. With investment in access to the Student and Trainee Mental Health program, utilization increased by 25.7%, with 1,231 more visits in 2020 compared to the number of visits in 2019, prior to the COVID-19 pandemic. The creation of Recharge Rooms had a positive impact on the well-being of health care workers. After a single fifteen-minute experience in the Recharge Room, an average 59.6% reduction in self-reported stress levels was noted by users. Other interventions were noted to be helpful in regular town hall meetings with trainees. Conclusion: Addressing trainee well-being is an essential aspect of a crisis response. The Mount Sinai Health System was able to care for the physical, mental, psychosocial, and safety needs of our trainees thanks to the collaborative effort of a pre-existing institutional well-being program and the GME Office. The ability to implement such a response was enabled by our well-being foundation, which allowed leadership at the highest institutional level and the Office of GME to provide support in response to this unprecedented crisis

Looking our limitations in the eye: A call for more thorough and honest reporting of study limitations

The replication crisis and subsequent credibility revolution in psychology have highlighted many suboptimal research practices such as p‐hacking, overgeneralizing, and a lack of transparency. These practices may have been employed reflexively but upon reflection, they are hard to defend. We suggest that current practices for reporting and discussing study limitations are another example of an area where there is much room for improvement. In this article, we call for more rigorous reporting of study limitations in social and personality psychology articles, and we offer advice for how to do this. We recommend that authors consider what the best argument is against their conclusions (which we call the “steel‐person principle”). We consider limitations as threats to construct, internal, external, and statistical conclusion validity (Shadish et al., 2002), and offer some examples for better practice reporting of common study limitations. Our advice has its own limitations — both our representation of current practices and our recommendations are largely based on our own metaresearch and opinions. Nevertheless, we hope that we can prompt researchers to write more deeply and clearly about the limitations of their research, and to hold each other to higher standards when reviewing each other's work
