Engineering Properties of Self Compacting Concrete Incorporating Metakaolin and Rice Husk Ash: A Review
Analysis of Heavy Metal Ions in Potable Water Using Soft Computing Technique
AbstractThe water quality analysis has been an intriguing subject in the recent years because of the issues related to water resources. The work presents the application of the genetic algorithm to water samples containing contaminants for the optimal selection of electrode and the corresponding frequency for the better classification of various contaminants. We have used 24 water samples containing 8 different heavy metal ions (Cd, Co, Zn, Ni, Cu, Cr, Ar and Pb) for our experiment. The electrodes used were Gold, Platinum, Glassy Carbon and Silver Nanoparticle electrode. The impedance values of these four electrodes are recorded as Single-Electrode Multi-Frequency (SEMF), Single-Frequency Multi-Electrode (SFME) and Multi-Electrode Multi-Frequency (MEMF). The impedance values are subjected to Principal Component Analysis. Further, the optimal classification of various metal ions present in the water samples is done using Genetic Algorithm and this is validated by the application of Davis Bouldin index. The results show that DBI value may be enhanced by choosing electrode with optimum frequency
Right/Left Hemisphere Lateralization: Correlation Between Individual Differences in Subjective Wellbeing, Happiness, Life Satisfaction, Success, Personality and Thinking Styles
There has been a popularization in society of the Right hemisphere of the brain being responsible for creativity, and the Left hemisphere being responsible for logical and analytical thinking. However, it is not fully understood whether there is an underlying, neuroscientific basis to these claims or if such claims can be rendered factual. Recent studies have been conducted, revealing that right brained leaders emphasize in innovation and managing whereas left brained leaders focus on continuous improvement and planning (Kumar & Sharma 2016). The right and left hemispheres do possess interconnectedness, however as this study has shown, individuals tend to possess dominance on either hemisphere of their brain, which can then be associated with thinking styles and leadership; traits relating to the overall success of an individual, their life satisfaction, happiness, subjective well-being, and personality. Other studies have shown that there is a correlation between hemispheric dominance and the emotional intelligence in college students, which was correlated to a student’s academic success according to their score in emotional intelligence (Margaret & Lavanya 2017). From these two studies, other variables that are related to emotional intelligence, leadership, and thinking styles can be studied. Such variables include: individual personality, subjective happiness, subjective well-being, life satisfaction, and objective life success. This study hopes to determine the relation between hemispheric dominance and the mentioned variables in college students in the hopes of categorizing each participant, based on their responses, to being more left hemisphere or right hemisphere dominant, and identifying the implications of dominance as they relate to these variables
Mucous Membrane Pemphigoid with Different Manifestations
Background- The study aimed to assess the different manifestations of MMP among patients diagnosed as MMP.
Methodology- The study was conducted as a cross sectional study at PMCH, Patna for a period of 5 years on 30 patients diagnosed as a case of MMP in the departments of Otorhinolarungology, dermatology and ophthalmology. Detailed history regarding clinical features, mode of presentation, and duration of symptoms was obtained and entered in questionnaire. Statistical analysis- Data was compiled using MsExcel and analysed using IBM SPSS 20. Categorical data was expressed as frequency and percentage.
Results- Majority of patients with MMP belonged to 61 to 80 years of age (83.3%) and majority of cases were females. The most common site of involvement was oral mucosa (96.7%), followed by ocular conjunctiva in 63.3% and laryngeal mucosa (46.7%). About 55.8% patients with oral lesions presented with oral ulceration and about 47.4% cases with ocular lesions presented with non-specific conjunctivitis. In cases with laryngeal involvement, 28.6% cases presented with laryngeal stenosis with breathing difficulty. Nasal mucosal erosions, localized erythematous plaque, dysphagia and odynophagia were predominant manifestations in cases with nasal, skin, pharynx and oesophageal involvement respectively.
Conclusion-Mucous membrane pemphigoid is a rare disorder which most commonly involve oral mucosa. However, ocular, nasopharynx, larynx, oesophagus involvement can also be observed. Depending upon site of involvement, patients may present with varied manifestations such as oral erosions and ulcers, desquamtive gingivitis in case of oral lesions, cicatrizing conjunctivitis in case of ocular involvement
Impact on optical, electrical and antibacterial response of microwave irradiated silver nanoparticles
Silve spectroscopy, Fourier transform infrared spectroscopy (FTIR), photoluminescence, Raman spectroscopy, X-ray powder diffraction (XRD), scanning and transmission electron microscopy (SEM–TEM), zeta potential and dynamic light scattering (DLS). The presence of surface plasmon resonance (SPR) band (416 nm) confirmed fabrication of AgNPs. The effect of microwave irradiation time showed that the size, shape and stability of AgNPs depend on increasing of peak intensity with increasing reaction time. FTIR spectrum confirmed the possible functional group in the product indicating presence of PVP. The enlargement in the size and agglomeration of nanoparticles were prevented by r nanoparticles (AgNPs) have been formulated using microwave irradiation from non-aqueous solution of silver nitrate (AgNO3) and poly (N-vinyl-2-pyrrolidone) (PVP) as a stabilizer. Ethanol has also been reacted like a reducer for microwave irradiation process which is quite rapid, homogeneous and efficient. The as synthesized AgNPs was further characterized by ultraviolet–Visible (UV–Vis)encapsulation of PVP during the reaction. XRD spectra illustrated that AgNPs are higher crystalline having face-centered cubic surface. The morphological analysis found that the AgNPs are homogeneous and spherical with the size of 18 ± 5 nm. The zeta potential measurement affirms the higher stability of AgNPs due to its negatively charged surface. The prepared AgNPs also exhibited electrical properties obeying the ohm’s law and significantly antimicrobial activities against Escherichia coli due to the small size
A Study Towards the Standardisation of Parameters for Testing of Air Purifiers
Abstract Performance evaluation of an air purifier in a controlled chamber environment to assess its effectiveness under varying airflow conditions (within chamber, i.e. recirculation fan (RF) and ceiling fan (CF)) using smoke and salt particles was conducted. Clean Air Delivery Rate (CADR) of an air purifier (AP) was measured following the Association of Home Appliances and Manufacturers (AHAM AC-1:2013) standard, with values of 500 ± 10 m3 h−1 for smoke, 471 ± 7 m3 h−1 for ammonium sulphate, and 488 ± 9 m3 h−1 for potassium chloride particles, closely aligned with the certified (as per GB/T 18801:2015 standard) CADR of 520 m3 h−1. These measured values against certified values validated the testing facility and the methodology used for its measurement capabilities. Deposition rate (natural decay) analysis revealed significant size-specific variations, for smoke particles of diameter ≤ 1 and 2 µm, the deposition rates vary from 0.68 to 0.89 h−1 under calm condition (when RF and CF were in off position) to 5.33–7.59 h−1 for turbulent conditions (when RF and CF were on). Ammonium sulphate particles showed a size-dependent (0.5–5 µm) increase in deposition rates, ranging from 0.30 to 3.54 h−1 under calm conditions to 0.84–6.90 h−1 under turbulent conditions. Similarly, potassium chloride particles exhibited deposition rates ranging from 0.48 to 1.72 h−1 under calm conditions, increasing to 0.72–4.14 h−1 under turbulent conditions. Study revealed that size-specific particle removal efficiency of AP varied with particle diameter, effectively removing smaller particles (< 1 µm) under calm conditions due to enhanced Brownian diffusion and effective filtration. While, larger particles exhibited higher removal through inertial impaction and gravitational settling. Under turbulent conditions, increased particle resuspension resulted in lower removal efficiencies across all particle types than calm conditions. These findings emphasize the importance of refining the CADR evaluation standards by incorporating size-specific efficiency metrics and assessing performance under dynamic airflow conditions. Additionally, this study suggests that manufacturers should provide CADR specifications for multiple fan speed settings, enabling for more accurate performance assessments allowing consumers to choose devices that best suit their requirement.
