Fission of hyper-hyperdeformed 56^{56}Ni: a clustering analysis with in mean-field approaches

The structure of 56Ni is sudied by using the non-relativistic Skyrme Hartree-Fock and the relativistic Hartree approximation in an axially deformed cylindrical coordinate. We found several intrinsic excited states, including the spherical ground-state solution. Without including any extra $\alpha$-cluster correlations, the possible cluster configurations of the resonance states are analyzed, showing the multipleN=Z, $\alpha$-nucleus like, cluster structures for hyper-deformed states, but, contrary to the recent experimental possibility of a ternary fission decay, we predict a two cluster or symmetric fission configuration for the hyper-hyperdeformed stat

Natural nitrification inhibitors for higher nitrogen use efficiency, crop yield, and for curtailing global warming

Nitrification inhibitors selectively inhibit microbial enzymes responsible for the conversion of NH4+ to NO3-. Arresting nitrification could be a key strategy to improve nitrogen (N) recovery and agronomic N use efficiency in situations where the loss of N is significant. Although chemicals known to inhibit nitrifiers have been tested, many of these are still at the experimental level; high cost, limited availability, adverse influence on beneficial soil microorganisms, and above all, poor extension and promotional activities are major constraints in this respect. It is therefore necessary to develop plant-based nitrification inhibitors (natural nitrification inhibitors, NNI) for augmenting nitrogen use efficiency, crop productivity, and for safeguarding the environment. The advantages of NNI are that they are easily available, cheap, and eco-friendly. This paper briefly reviews the different aspects of plant-based nitrification retarder

Integrated weed management of medicinal plants in India

The present as well as future need is to diversify the agro-ecosystem and to minimize or overcome the bad effects of global warming and climate change. Medicinal plants survive very well in the current scheme of crop diversification in various types of agro-climatic conditions of India. Agronomists are posed with challenge of scientifically fitting most suitable medicinal plants in different ago-climatic regions. Among the losses caused by different pests in the agriculture, the weeds account for about 45% and it may be more or less equal in the case of medicinal plants. Integrated weed management increases the factor productivity, income of the farmer, quality of produce and is eco-friendly in nature. By taking examples of two important medicinal plants viz. Satawar (Asparagus racemosus Willd.) and Kalmegh (Andrographis paniculata Nees.), the present review discusses the different methods of weed management and how they may be integrated to develop new paradigm as an integrated weed management

Multi-criteria assessment to screen climate smart rice establishment techniques in coastal rice production system of India

Introduction: Conventional rice production techniques are less economical and more vulnerable to sustainable utilization of farm resources as well as significantly contributed GHGs to atmosphere. Methods: In order to assess the best rice production system for coastal areas, six rice production techniques were evaluated, including SRI-AWD (system of rice intensification with alternate wetting and drying (AWD)), DSR-CF (direct seeded rice with continuous flooding (CF)), DSR-AWD (direct seeded rice with AWD), TPR-CF (transplanted rice with CF), TPR-AWD (transplanted rice with AWD), and FPR-CF (farmer practice with CF). The performance of these technologies was assessed using indicators such as rice productivity, energy balance, GWP (global warming potential), soil health indicators, and profitability. Finally, using these indicators, a climate smartness index (CSI) was calculated. Results and discussion: Rice grown with SRI-AWD method had 54.8 % higher CSI over FPR-CF, and also give 24.5 to 28.3% higher CSI for DSR and TPR as well. There evaluations based on the climate smartness index can provide cleaner and more sustainable rice production and can be used as guiding principle for policy makers.publishedVersio

Open data from the third observing run of LIGO, Virgo, KAGRA, and GEO

The global network of gravitational-wave observatories now includes five detectors, namely LIGO Hanford, LIGO Livingston, Virgo, KAGRA, and GEO 600. These detectors collected data during their third observing run, O3, composed of three phases: O3a starting in 2019 April and lasting six months, O3b starting in 2019 November and lasting five months, and O3GK starting in 2020 April and lasting two weeks. In this paper we describe these data and various other science products that can be freely accessed through the Gravitational Wave Open Science Center at https://gwosc.org. The main data set, consisting of the gravitational-wave strain time series that contains the astrophysical signals, is released together with supporting data useful for their analysis and documentation, tutorials, as well as analysis software packages

HISTOMORPHOLOGICAL STUDY OF ENDOCRINE CELLS IN VARIOUS REGION OF DIGESTIVE TRACT OF BUFFALO (BUBALUS BUBALIS)

The histomorphology of enteroendocrine cells were studied in different segments of gastrointestinal tract of six adult buffalo. Depending upon the histomorphological study, the enteroendocrine cells were divided into 7 different types viz. oval cell (type I), pyriform cell (type II), spherical or rounded cell (type III), elongated cell (type IV), pyramidal cell (typeV), spindle cell (type VI) and large oblong cell (type VII). Further the granulation pattern of the cell types were noted as basal granulation, dense granulation, peripheral granulation and diffuse granulation.The endocrine cells revealed differential staining character with each of the stain (Masson-Haemperl argentaffin reaction, Grimelius silver technique, Ferric ferricyanide reduction reaction, Lead haematoxylin) employed in the present study depending upon their physiological status
