Spiritual Concern in the Works of Manoj Das
No full textMy aim through this article is to discuss the issue of spirituality in Manoj Das’s works which can be seen in many forms and ideas in his exquisite narration. He narrates an Indian experience in language which is alien or not Indian at the same time. He does not loose original Indian charm and ethos. In his works he shows his deep concern with spirituality. In his works spirituality is not a figment of imagination or a religious dogma or any firm ideology but it is a domain of realization where we realize (experience) values like truth, goodness, beauty, love, compassion, and also intuition, creativity, insight and focused attention in all walks of life. When he begins his concern with spirituality, he talks about “Soul’”. For him soul- a point of non-material energy, eternal in form and identity. The soul is not subject to change as is the body
A short-term decline in anthropogenic emission of CO<sub>2</sub> in India due to COVID-19 confinement
No full textTo curb the spread of novel coronavirus (COVID-19), confinement measures were undertaken, which altered the pattern of energy consumption and India’s anthropogenic CO2 emissions during the effective lockdowns periods (January to June 2020). Such changes are being analyzed using data of energy generated from coal and renewable sources and fossil-based daily CO2 emissions. Results revealed that coal-fired (fossil-based) energy generation fell by –13% in March, –29% in April, and –20% in May, and –16.6% in mid-June 2020 as compared with the same period in 2018–2019. Conversely, the renewable energy generation increased by 19% in March, 12% in April, 17% in May, and 7% in June 2020. The share of fossil-based energy fell by –6.55% in 2020 compared with mean levels, which was further offset by increases of renewable energy. India’s daily fossil-based CO2 emissions fell by –11.6% (–5 to –25.7%) by mid-June 2020 compared with mean levels of 2017–2019 with total change in fossil-based CO2 emission by –139 (–62 to –230) MtCO2, with the largest reduction in the industry (–41%), transport (–28.5%), and power (–21%) followed by the public (–5.4%), and aviation (–4%) sectors. If some levels of lockdown persist until December 2020, both energy consumption and CO2 emissions patterns would be below the 2019 level. The nationwide lockdown has led to a reduction in anthropogenic CO2 emissions and, subsequently, improved air quality and global environment and has also helped in reducing atmospheric CO2 concentrations at the local level but not on the global level. With suitable government policies, switching to a cleaner mode of energy generation other than fossil fuels could be a viable option to minimize CO2 emissions under increasing demand for energy.</p
Determination of the mutual orientation between proton CSA tensors mediated through band-selective 1H–1H recoupling under fast MAS
No full textThe mutual orientation of nuclear spin interaction tensors provides critical information on the conformation and arrangement of molecules in chemicals, materials, and biological systems at an atomic level. Proton is a ubiquitous and important element in a variety of substances, and its NMR is highly sensitive due to their virtually 100% natural abundance and large gyromagnetic ratio. Nevertheless, the measurement of mutual orientation between the 1H CSA tensors has remained largely untouched in the past due to strong 1H–1H homonuclear interactions in a dense network of protons. In this study, we have developed a proton-detected 3D 1H CSA/1H CSA/1H CS correlation method that utilizes three techniques to manage homonuclear interactions, namely fast magic-angle spinning, windowless C-symmetry-based CSA recoupling (windowless-ROCSA), and a band-selective 1H–1H polarization transfer. The asymmetric 1H CSA/1H CSA correlated powder patterns produced by the C-symmetry-based methods are highly sensitive to the sign and asymmetry parameter of the 1H CSA, and the Euler angle β as compared to the symmetric pattern obtained by the existing γ-encoded R-symmetry-based CSA/CSA correlation methods and allows a larger spectral area for data fitting. These features are beneficial for determining the mutual orientation between the nuclear spin interaction tensors with improved accuracy.This is a manuscript of an article published as Kobayashi, Takeshi, Yusuke Nishiyama, and Manoj Kumar Pandey.

Improvement in air quality and its impact on land surface temperature in major urban areas across India during the first lockdown of the pandemic
No full textThe SARS CoV-2 (COVID-19) pandemic and the enforced lockdown have reduced the use of surface and air transportation. This study investigates the impact of the lockdown restrictions in India on atmospheric composition, using Sentinel–5Ps retrievals of tropospheric NO2 concentration and ground-station measurements of NO2 and PM2.5 between March–May in 2019 and 2020. Detailed analysis of the changes to atmospheric composition are carried out over six major urban areas (i.e. Delhi, Mumbai, Kolkata, Chennai, Bangalore, and Hyderabad) by comparing Moderate Resolution Imaging Spectroradiometer (MODIS) Aerosol Optical Depth (AOD) and land surface temperature (LST) measurements in the lockdown year 2020 and pre-lockdown (2015–2019). Satellite-based data showed that NO2 concentration reduced by 18% (Kolkata), 29% (Hyderabad), 32-34% (Chennai, Mumbai, and Bangalore), and 43% (Delhi). Surface-based concentrations of NO2, PM2.5, and AOD also substantially dropped by 32–74%, 10–42%, and 8–34%, respectively over these major cities during the lockdown period and co-located with the intensity of anthropogenic activity. Only a smaller fraction of the reduction of pollutants was associated with meteorological variability. A substantial negative anomaly was found for LST both in the day (–0.16 °C to –1 °C) and night (–0.63 °C to –2.1 °C) across select all cities, which was also consistent with air temperature measurements. The decreases in LST could be associated with a reduction in pollutants, greenhouse gases and water vapor content. Improvement in air quality with lower urban temperatures due to lockdown may be a temporary effect, but it provides a crucial connection among human activities, air pollution, aerosols, radiative flux, and temperature. The lockdown for a shorter-period showed a significant improvement in environmental quality and provides a strong evidence base for larger scale policy implementation to improve air quality
Motility driven glassy dynamics in confluent epithelial monolayers
No full textAs wounds heal, embryos develop, cancer spreads, or asthma progresses, the cellular monolayer undergoes a glass transition between solid-like jammed and fluid-like flowing states. During some of these processes, the cells undergo an epithelial-to-mesenchymal transition (EMT): they acquire in-plane polarity and become motile. Thus, how motility drives the glassy dynamics in epithelial systems is critical for the EMT process. However, no analytical framework that is indispensable for deeper insights exists. Here, we develop such a theory inspired by a well-known glass theory. One crucial result of this work is that the confluency affects the effective persistence time-scale of active force, described by its rotational diffusivity, Deffr. Deffr differs from the bare rotational diffusivity, Dr, of the motile force due to cell shape dynamics, which acts to rectify the force dynamics: Deffr is equal to Dr when Dr is small and saturates when Dr is large. We test the theoretical prediction of Deffr and how it affects the relaxation dynamics in our simulations of the active Vertex model. This novel effect of Deffr is crucial to understanding the new and previously published simulation data of active glassy dynamics in epithelial monolayers
Determination of the relative orientation between 15N-1H dipolar coupling and 1H chemical shift anisotropy tensors under fast MAS solid-state NMR
No full textIn this work, we have proposed a proton-detected three-dimensional (3D) 15N -1H dipolar coupling (DIP)/1H chemical shift anisotropy (CSA)/1H chemical shift (CS) correlation experiment to measure the relative orientation between the 15N -1H dipolar coupling and the 1H CSA tensors under fast magic angle spinning (MAS) solid-state NMR. In the 3D correlation experiment, the 15N -1H dipolar coupling and 1H CSA tensors are recoupled using our recently developed windowless C-symmetry-based C313-ROCSA (re -coupling of chemical shift anisotropy) DIPSHIFT and C313-ROCSA pulse-based methods, respectively. The 2D 15N -1H DIP/1H CSA powder lineshapes extracted using the proposed 3D correlation method are shown to be sensitive to the sign and asymmetry of the 1H CSA tensor, a feature that allows the determination of the relative orientation between the two correlating tensors with improved accuracy. The experimental method developed in this study is demonstrated on a powdered U -15N L-Histidine.HCl center dot H2O sample.This is a manuscript of an article published as Sehrawat, Neelam, Ekta Nehra, Ketan Kumar Rohilla, Takeshi Kobayashi, Yusuke Nishiyama, and Manoj Kumar Pandey.

Potential of rainwater harvesting in Nepal : a case study
No full textThis paper gives an overview of RWHS in urban Kathmandu valley (27°32’13”- 27°49’10” N 85°11’31” & 85°31’38” E). The rainwater collection is during monsoon season (June-August) and some amount of water can be collected by rainwater in dry period to minimize the daily water demand among different households. The main study of research is to analyze and interpret the collected rainwater and household catchment area together to know the capacity of individual household of different land sizes. The research ultimately gives the framework of design storage tank depending on amount of rainfall collected from different roof catchment areas.
The annual rainfall data of Kathmandu valley (2003-2013) is collected from department of hydrology and meteorology. The roof catchment area and land size data of different households in ward-9 were collected from ward office of KMC. The household land sizes and roof catchment area of different land area (2-4,4-6,6-8,8-10,10-12) Anna gives different rainwater harvesting potentially that amount of rainwater can be harvested. This is basis for design of the harvesting system. The capacity of collecting rainwater depends on roof catchment area and there is more collection of rainwater as the catchment roof area increases accordingly with respect to land area. The monthly precipitation of Kathmandu valley is more in June – September with monthly precipitation of 215mm, 375 mm, 315 mm and 244 mm and average area roof surface of 2-4 Anna is 72.66m2 and it increases to 167.38m2 of 10-12 Anna.
The collected data shows that there is high potential of water harvesting and collected water can be useful as a domestic resource. The household member gets benefitted with an additional water source by the use of simple and easily accessed technology. In the same way there is less water supply pressure to the government and authorized institutional bodies, and ultimately beneficial for environmental risk of flooding as well.M-MIN
Spiritual Strain in Chasing The Rainbow: Growing Up in An Indian Village
No full textChasing the Rainbow: Growing up in an Indian Village is a collection of short stories written by Manoj Das. It was published in 2004. It is part memoir, part social history of a vanishing ethos. This genre, in particular, seems to be more suitable for the mirroring the Indian life since its writer is free to choose any one part of life and deals it with utmost care and sincerity which it requires. Manoj Das is one of the greatest short story writers of India. Ruskin Bond, an acclaimed short story writer and novelist, remarks, “There are only a few good storytellers left in the world today and one of them is Manoj Das” (blurb on Das’s The Escapist)
