Authors: . Durvesh , Singh Raj Kumar , K. Manjunath 
Published: May 2023

Abstract
Numerous impellers are placed in line on a same shaft in a multistage centrifugal pump, comprises impeller, diffuser and return channel. A return channel is employed to direct the flow to the following impeller. This article uses numerical simulation to demonstrate and explain the performance evaluation of a two-stage centrifugal pump. To carry out numerical flow simulation for multistage, stage analysis is performed for each stage. Domain for simulation was created using Creo Parametric software and ANSYS Fluent 2022R1 was used for simulation. The flow simulation is carried out by using the k-ε turbulence model. The flow analysis of first stage is carried out for a different number of blades, viz. 5, 6, and 7, for different speeds varying from 1450 rpm to 1900 rpm. It was observed that 7 blade number and 1900 rpm are optimum in range as it gives the best performance results i.e. H=49.34m & η= 54.65%. The optimal solutions from the first-stage were used to analyse the second-stage. The first stage's flow differs markedly from the following stages. It was observed that losses in diffuser of 1st stage and 2nd stage are almost same but head losses in return passage of 1st stage and 2nd stage are having difference of 19.99%, 28.5%, and 23.59% for 5, 6, and 7 blades respectively. The findings show that the multistage simulation could more accurately mirror the actual flow than the two-stage simulation, but that it also had more demanding computer configuration requirements. Two-stage simulation is a good option for estimating pump performance because it strikes a better balance between computation time and numerical precision. The findings of this research present as a foundation and reference point for future enhancements to multistage centrifugal pump performance.

Published: May 2023

Abstract
This study uses fractal theory to investigate the spatial characteristics of traditional Tibetan villages in western Sichuan. The objective is to analyze the fractal properties of the landscape space in Tibetan villages from diverse regions and cultural backgrounds and explore the relationship between fractal characteristics and regional culture. The study examines the morphological features and generation mechanisms of landscape spatial characteristics in traditional Tibetan villages, offering a scientific basis for cultural heritage preservation and transmission. Three sample villages with distinct regional and cultural backgrounds are selected: Xisuo Village representing the Jajong Tibetans, Shenzuo Village representing the Amdo Tibetans, and the Ethnic Village representing the Baima Tibetans. Field surveys and data collection are conducted to calculate the fractal dimensions and influencing factors of various landscape elements by means of box-counting dimensions and multiple regression analysis. These results are then compared and validated against each village’s actual landscape spatial characteristics. The research findings demonstrate that the landscape spatial characteristics of traditional Tibetan villages in different regions and cultural backgrounds exhibit diverse and intricate fractal properties intimately linked to the natural environment, religious beliefs, and folk culture. By analyzing the morphological features of the landscape space in Tibetan traditional villages from a multidimensional perspective, this study unveils their intrinsic fractal patterns, generative mechanisms, and cultural significance. Fractal theory can offer novel insights into preserving traditional village heritage and maintaining cultural traditions.
Shaping Robust Dynamic Inversion Control of Neural Cell Dynamics
Authors: Yue Rongting , Dutta Abhishek 
Published: May 2023

Abstract
The human brain consists of 100 billion neurons connected to each other with synapses. When a neuron reaches a threshold voltage, due to the summation of currents flowing in from synapses or by external stimulation, the neuron fires with an action potential, observed as a voltage spike. The nonlinear firing behavior together with the firing rate gives rise to synaptic plasticity and forms the basis of memory, perception, action, and behavior. The perturbed firing of neurons will evolve into undesirable mental states linked to various neurological disorders. Closed-loop control of neuronal firing is thus desirable but challenging due to the underlying highly nonlinear dynamics. In this study, we propose Shaping Robust Dynamic Inversion (SRDI) as a novel robust nonlinear control approach for controlling neuron spiking. We apply SRDI to a Hodgkin-Huxley model to achieve controlled neuron spiking. We compare the performance of SRDI with classical dynamic inversion and linear model predictive control, and our findings demonstrate that SRDI outperforms the other two methods for robust and precise control over firing behavior, enabling neurons to spike at desired moments.

Abstract

Molecular catalysts play a significant role in chemical transformations, utilizing changes in redox states to facilitate reactions. In the broadening field of carbon dioxide (CO2) electrolysis to value-added products, catalyst choice strongly impacts product formation. To date molecular electrocatalysts have efficiently produced single-carbon products from CO21–3 but have struggled to achieve the carbon-carbon coupling step needed to reach highly valued multi-carbon products. Conversely, copper acts as the only reliable bulk metal that enables carbon-carbon coupling, but leads to broad C2+ product spectrums.3–5 Here we designed a molecular electrocatalyst system that subverts the traditional redox-mediated reaction mechanisms of organometallic compounds, facilitating electrochemical CO2-to-ethanol yields of 96% at optimal conditions with trace methanol and C3 products. By coupling iron tetraphenylporphyrin (Fe-TPP) with a nickel electrode, we fixed the iron oxidation state during electrocatalytic CO2 reduction to enable further reductions and coupling of *CO intermediates. This represents a marked behavioural shift compared to the same metalloporphyrin deposited onto carbon-based electrodes. Extending the approach to a 3D porous nickel support with adsorbed Fe-TPP, we attain ethanol faradaic efficiencies of 68% +/- 3.2% at -0.3 V vs a reversible hydrogen electrode (pH = 7.7) with partial ethanol current densities of -21 mA cm-2. Separately we demonstrate maintained ethanol production over 60 hours of operation. Further consideration of the wide parameter space of molecular catalyst and metal electrodes shows promise for additional novel chemistries and achievable metrics.

Abstract: The tourism sector is one of the main economic cogs of a country. Halal tourism is part of the tourism industry that provides tourist services based on Islamic rules for Muslim tourists but does not rule out the possibility of its use by non-Muslim tourists. This paper discusses the development of halal tourism in East Java and what factors are obstacles to the development being achieved using qualitative methods, especially by using literature studies. The Indonesian government is trying to develop the potential of halal tourism throughout Indonesia. East Java is one of the regions rich in halal tourist destinations that have the potential to develop and become the main destination for local and foreign tourists. With the majority of the population who are also Muslims, the road to get there seems to look smooth. But in fact, the development of halal tourism in East Java is still far from expectations and arguably far from its true potential.
