Study on System Topologies for Enhancing Potential of Fuel Cell System

Fuel cell is most promising power source for hybrid operation with conventional and non-conventional energy source. This is due to its operating temperature, power matching and remote application. The fuel cell based distributed generator (DG) source can be operated in combined with wind turbine, photovoltaic generation system, gas turbine and many more. The hybrid operation of fuel cell with conventional DG source may increase the reliability, power quality and system stability. This paper presents the review on hybrid operation of fuel cell with other conventional DG system in utility interconnected mode. In this, it is addressed that, the fuel cell and its hybrid operation with other power generation application are given. Also the various controlling techniques can be used for its optimum operation which are also mentione

Study on Voltage Controlling Techniques In Grid Connected PV System

The energy is the very important parameter for survival or today’s growth we can transfer the energy from one form to other. The mainly wind and solar energies are the most available among other renewable energy sources in all over the world. In the present years, because of the rapid advances of power electronic systems the production of electricity from wind and photovoltaic energy sources have increased significantly. This paper proposed hybrid system is using of controlling power

The poetry of Swami Vivekananda: An Exploration into the Romanticism

The present research paper focuses on the Romantic traits and tendencies in the poetry of Swami Vivekananda. Swami Vivekananda is the initial signature of poetry on the manuscript of Indian English literature. Generally applauded as the fiery orator in the world, his poetic introduction has almost been unnoticed by the critical pens. He is not a poet who compiles volume after volume but writes when he is overwhelmed by ‘the spontaneous overflow of powerful feelings’. His poetry is remarkable for various romantic traits. The portrayal of child, love to humanity, love for love’s sake, freedom, imagery and imagination are the echoes of Romanticism in his poetry.  He reminds us of Wordsworth, Coleridge, Shelley and Keats in his instincts and poetic tendencies. His poems, though countable on the finger-tips, are the sublime poetic pieces of artistic culmination. This paper also focuses on the similarities and dissimarities of his poetry with the great poets of the Romantic era

Production and Partial Purification of a Neutral Metalloprotease by Fungal Mixed Substrate Fermentation

Five strains of fungi belonging to Aspergillus sp. were evaluated by casein agar plate assay and a wheat bran-based solid-state fermentation for selecting a neutral protease-producing culture. Based on the results, A. oryzae NRRL 2217 was selected for further studies. Sixteen different agro-industrial residues were evaluated for their potential to serve as a substrate for neutral protease production by this fungal strain. Results showed that a combination of coconut oil cake and wheat bran in the mass ratio of 1:3 was the best substrate for enzyme production. Various process parameters influencing protease production including fermentation time, initial moisture content, and fermentation temperature were optimised. The medium was supplemented with different nutrients in the form of organic and inorganic nitrogen and carbon sources. Supplementation of chitin increased the enzyme production significantly. Ammonium nitrate as inorganic nitrogen supplement slightly enhanced enzyme production. No organic nitrogen supplement was effective enhancer of enzyme production. Fermentation was performed under optimised conditions (initial moisture content V/m = 50 %, temperature 30 °C, 48 h). Partial purification of the enzyme resulted in a 3-fold increase in the specific activity of the enzyme. The partially purified enzyme was characterised by various features that govern the enzyme activity such as assay temperature, assay pH and substrate concentration. The effect of various metal ions and known protease inhibitors on the enzyme activity was also studied. The enzyme was found to be stable in pH range 7.0–7.5, and at temperature of 50 °C for 35 min. By the activating effect of divalent cations (Mg2+, Ca2+, Fe2+) and inhibiting effect of certain chelating agents (EGTA, EDTA), the enzyme was found to be a metalloprotease

Bhageerath: an energy based web enabled computer software suite for limiting the search space of tertiary structures of small globular proteins

We describe here an energy based computer software suite for narrowing down the search space of tertiary structures of small globular proteins. The protocol comprises eight different computational modules that form an automated pipeline. It combines physics based potentials with biophysical filters to arrive at 10 plausible candidate structures starting from sequence and secondary structure information. The methodology has been validated here on 50 small globular proteins consisting of 2–3 helices and strands with known tertiary structures. For each of these proteins, a structure within 3–6 Å RMSD (root mean square deviation) of the native has been obtained in the 10 lowest energy structures. The protocol has been web enabled and is accessible at

Neuromatch Academy: a 3-week, online summer school in computational neuroscience

Neuromatch Academy (https://academy.neuromatch.io; (van Viegen et al., 2021)) was designed as an online summer school to cover the basics of computational neuroscience in three weeks. The materials cover dominant and emerging computational neuroscience tools, how they complement one another, and specifically focus on how they can help us to better understand how the brain functions. An original component of the materials is its focus on modeling choices, i.e. how do we choose the right approach, how do we build models, and how can we evaluate models to determine if they provide real (meaningful) insight. This meta-modeling component of the instructional materials asks what questions can be answered by different techniques, and how to apply them meaningfully to get insight about brain function
