A simple, novel, and less cost yellow (Erythrosine) modified pencil graphite electrode (Po-ERY/MGPE) was successfully fabricated via electropolymerization method using cyclic voltammetric techniques. The fabricated Po-ERY/MGPE opted as a sensor for the detection of Adrenaline (ADR) in 0.2 M PBS (7.4 pH). This reported senor displayed excellent electrocatalytic activity, increased sensitivity, high stability, superior electron transfer kinetics in the oxidation of ADR once relative to BGPE. The significance of pH, scan rate, and impact of concentration was assessed at the sensor. As per the pH and scan rate study, redox routes carry the same number of electrons and protons, and electro-oxidation of ADR was adsorption controlled respectively. The LOD of ADR was found to be 0.499 µM. The DPV data indicate that there is a significant peak divergence among ADR and uric acid (UA) which could make it easier to determine them alone and simultaneously on the sensor. The described method has been employed for the determination of ADR in injection sample. Good recovery values indicate the efficacy and applicability of the sensor in detecting ADR.
Given that citizen participation is considered the main pillar of ‘Development’, the political economy behind its practice (behaviour and utilisation) remains a question. To disentangle the complex web of relationships that the governance shares with the citizens’ interface, it would be worthwhile to examine the whole phenomenon at the grass root level. A review of issues surrounding democracy has led different schools of thought to realise the need for adopting a holistic development approach for ensuring citizens’ participation in development processes. One such school believes that it is only through addressing governance bottlenecks and ensuring spaces for participation in policy design, programme formulation and implementation supplemented with proper monitoring, that ‘real’ development can be achieved. It is also universally accepted that governance is an enabler for socio-economic transformation and this can help in the improvement of lives through the eradication of structural inequality. Hence, strengthening the local governments is critical for ensuring citizen empowerment, civic participation and better service delivery. Furthermore, governance is measurable and can be monitored; thus can ensure a measurable implementation, accountability and monitoring framework (Global Thematic Consultation on Governance and the Post-2015 Development Framework, 2013). Against these backdrops, the current study endeavours to unearth plausible factors influencing the health behaviour of rural people examining a case of India’s National Sanitation Program—Swachh Bharat Mission in Odisha villages. Analysis of primary data collected from six districts across different regions of the Odisha state shows that various managerial, governance and social factors have a significant effect on the health behaviour of people and present more insightful results.
In today's society, time is considered more valuable than money, and researchers often have limited time to find relevant papers for their research. Identifying and accessing essential information can be a challenge in this situation. To address this, the personalized suggestion system has been developed, which uses a user's behavior data to suggest relevant items. The collaborative filtering strategy has been used to provide a user with the top research articles based on their queries and similarities with other users' questions, thus saving time by avoiding time-consuming searches. However, when rating data is abundant but sparse, the usual method of determining user similarity is relatively straightforward. Furthermore, it fails to account for changes in users' interests over time resulting in poor performance. This research proposes a new similarity measure approach that takes both user confidence and time context into account to increase user similarity computation. The experimental results show that the proposed technique works well with sparse data, and improves accuracy by 16.2% compared to existing models, especially during prediction. Furthermore, it enhances the quality of recommendations.
Due to improper postures, and unhealthy lifestyle of millennials, there has been an exponential increase in spinal cord related diseases. These include Slip Discs, Spine Injuries, Tumours, etc. each of which has multiple side-effects on the human body. To analyze these conditions, a wide variety of image processing models are developed by researchers. But most of these models do not analyze side-effects of spinal cord tumours on other body parts, due to which their applicability is limited when used for clinical trials. The main novelty of this work is to analyze side effects resulting due to spinal cord tumours, and to perform this task a novel Bioinspired Reinforcement Learning Model for Side-Effect Analysis of Spinal Cord Tumours is discussed in this text. The proposed model initially uses a Recurrent Neural Network (RNN) based on combination of Long-Short-Term Memory (LSTM) & Gated Recurrent Unit (GRU) for extraction of highly dense image features. These features allow the model to estimate tumour positions in Computer Tomography (CT) scans. The extracted features are classified via the RNN Model, which assists in high accuracy classification & localization of spinal cord tumours. These classification & localization results are linked with blood reports to estimate side-effects on kidney, lungs, heart activity and vitamin levels. To perform this correlation, a Grey Wolf Optimization (GWO) Model is used, which assists in linking tumour type, and size with blood report parameters. The GWO Model evaluates a fitness function, that fuses tumour levels with its side-effects on individual body parts. This fusion is done via analysis of temporal blood reports, which evaluates effects of different tumour types-and-sizes on individual body parameters. Due to a combination of GWO with LSTM & GRU based RNN, the model is capable of showcasing high accuracy of tumour classification, with better precision of correlation with side effects when compared with state-of-the-art models. It was observed that the proposed model was able to achieve 98.5% accuracy for tumour classification, 96.4% correlation precision with kidney diseases, 95.8% correlation precision with lung diseases, 96.2% correlation precision with heart diseases, and 91.5% correlation precision with vitamin deficiencies. Due to such a high performance, the model is capable of deployment for real-time clinical applications.
A low-probability but serious self-extinction of smouldering incense sticks is an undesirable characteristic. This paper reports the investigations on its cause and remedy, conducted for an incense stick manufacturer. Measurement of smouldering rate and surface temperature of glowing incense stick tip of several known compositions were made by recording the time required for the propagation of smoldering front and using thermal camera respectively. Several possible explanations like presence of (a) phosphorous, potassium, and sodium related compounds, (b) inadvertent inclusion of inorganic compounds, and others ruled out the role of phosphorous and related compounds, and a simple role of inorganic compounds despite the fact that defective incense sticks invariably contained large fraction of silica (SiO2) as revealed by scanning electron microscopy/ energy dispersive X-ray diffraction (SEM/EDX). Ultimately the issue was traced to the presence of antigorite that must have got infused into the incense sticks through termite mud into the raw materials. X-ray diffraction (XRD) of incense stick samples confirmed silica is in the form of α-quartz associated with antigorite in all defective samples and also in termite mud infested sample. Thermal studies of the incense sticks using differential thermal analysis (DTA) show endothermic decomposition of defective samples at 550 to 580°C and is also confirmed through differential scanning calorimetry (DSC) which shows an endothermic peak around 576°C corresponding to the endothermic phase transformation temperature of antigorite. It is therefore inferred that the presence of materials like antigorite in combination with α-quartz in incense sticks produce significant endothermal decomposition leading to self-extinction. The primary practical cause has been traced to termite mud infusion into the raw materials used for making the incense sticks.

In this study, fiber laser beam welding was used to join 3 mm-thick nitronic-50 stainless steel. The effect of travel speed on the mechanical, microstructural, and corrosion properties of the weld joints was studied. The experimental findings reveal that travel speed significantly affected the size of bead geometry and the fusion boundary of the weld joints. The microstructure of columnar grains transformed into equiaxed dendritic grains at the center of the weld nugget due to fast cooling at higher travel speeds. The increase in ferrite content was due to the incomplete transformation of ferrite to austenite at higher travel speeds, which led to higher strength and microhardness in the weld joints. Similarly, the corrosion studies demonstrate that the weld joints made at higher travel speeds have superior corrosion resistance due to a higher fraction of equiaxed dendritic grains and smaller dendrites with less inter-dendritic arm spacing.

This main function of the robot is to automatically sense fires and shift against the fires to finish it with water by keeping a safe distancing from it. A programmable raspberry pi can completely control the movement and actions of this device. This device must move right, east, front and back in the shape of a car to locate and quench the fires. An infra-red camera and thermal camera is used in this fire-fighter robot. The thermal camera attempts to monitor the flames, temperature and the infra-red camera, offering pictures of the view of the night, which record the whole extinction period directly. This live capture can be seen in a PC file which is also accompanied by a log from the computer.
In this study, a concrete cube was created by partially replacing Ordinary Portland Cement (OPC) with Nano Materials such as Multi-walled Carbon Nano Tubes (MWCNTs), Titanium Di Oxide (TiO2), and Copper Oxide (CuO) at various percentages. MWCNTs were replaced by OPC by 0.01, 0.025, 0.05, and 0.075%, TiO2 by 0.25, 0.5, 0.75, and 1 percent, and CuO by 0.5, 1, 1.2, 1.5, and 2%. Using Nano Materials gives more compressive strength than normal concrete cubes, and MWCNT outperforms TiO2 and CuO. Simply to reduce cement usage Fly ash was used while the compressive strength and amount of Nano Materials remained constant. As much as 39% Ordinary Portland Cement can be replaced with up to 35% MWCNTs and Fly Ash, 35% TiO2 and Fly Ash, and up to 34% CuO and Fly Ash. According to the cost analysis, TiO2 with Fly Ash costs 26.77Rs to prepare a single cube with a maximum replacement of 35% of OPC, while MWCNTs and CuO with Fly Ash cost 146.86 and 42.51Rs to prepare a single concrete cube with a maximum replacement of 39 and 34%, respectively, and normal OPC concrete cubes require 27.98 Rs. In OPC concrete, almost TiO2 cube preparation took a 10% reduction when compared to Normal Concrete cube. In this work, the carbon score was calculated, and the maximum carbon emission reduction up to By replacing cement with MWCNTs and Fly Ash, OPC concrete cube can be reduced by 35%. As a result, we concluded that TiO2 with Fly Ash Nano Material concrete is the most cost-effective when compared to MWCNTs and CuO with Fly Ash.
