TL;DR: In this article, the adsorption potential and interaction of lead [Pb(II)] with natural clay and humic acid were investigated, and the results concluded that natural clay is promising adsorbents for limiting the mobility of Pb (II) ions in the soil system and aquatic environment, and this could be an effective method for lead waste management.
Abstract: Currently, the contamination by lead has become a serious issue to the environment, and many approaches are continuously been searched for its removal from the environment. In the present study, the adsorption potential and interaction of lead [Pb(II)] with natural clay and humic acid were investigated. X-ray diffraction analysis revealed quartz as a dominant mineral in natural clay. Maximum adsorption capacity of both natural clay and humic acid for Pb(II) was 25.07 and 19.16 mg/g, respectively, after the incubation time of 180 min and adsorbate and adsorbent concentrations of 20 mg/L and 10 g/L, respectively. Adsorption capacity of clay was found to be 1.3-folds greater than that of humic acid. Pb(II) adsorption on clay and humic acid was according to the Langmuir isotherm and followed the pseudo-second-order and intraparticle diffusion model kinetics. Fourier transform infrared spectra revealed that Si–O–Si and OH− groups in clay were involved in the interaction with Pb(II); and carboxylic acid, phenolic and alcoholic groups and alkyl halides in humic acid were involved in the interaction with Pb(II). Scanning electron microscopy and energy-dispersive X-ray spectra analysis revealed that Pb(II) adsorption on clay and humic acid occurred by replacement of Mg and Al ions, potentially by ion exchange mechanism. Overall, the results concluded that natural clay and humic acid are promising adsorbents for limiting the mobility of Pb(II) ions in the soil system and aquatic environment, and this could be an effective method for lead waste management.

TL;DR: An automated early diabetic retinopathy detection scheme from color fundus images through improved segmentation strategies for optic disc and blood vessels and Radial basis function neural network is used for classification of the diseases.
Abstract: This paper presents an automated early diabetic retinopathy detection scheme from color fundus images through improved segmentation strategies for optic disc and blood vessels. The red lesions, microaneurysms and hemorrhages are the earliest signs of diabetic retinopathy. This paper essentially proposes improved techniques for microaneurysm as well as hemorrhages detection, which eventually contribute in the overall improvement in the early detection of diabetic retinopathy. The proposed method consists of five stages- pre-processing, detection of blood vessels, segmentation of optic disc, localization of fovea, feature extraction and classification. Mathematical morphology operation is used for pre-processing and blood vessel detection. Watershed transform is used for optic disc segmentation. The main contribution of this model is to propose an improved blood vessel and optic disc segmentation methods. Radial basis function neural network is used for classification of the diseases. The parameters of radial basis function neural network are trained by the features of microaneurysm and hemorrhages. The accuracy of the proposed algorithm is evaluated based on sensitivity and specificity, which are 87% and 93% respectively.
TL;DR: It is found from the analysis that high turbulent fields generated inside the isolation room may be an effective way of distributing sanitizer in entire volume of isolation room to kill the COVID-19 virus.
Abstract: The COVID-19 is a severe respiratory disease caused by a devastating coronavirus family (2019-nCoV) has become a pandemic across the globe. It is an infectious virus and transmits by inhalation or contact with droplet nuclei produced during sneezing, coughing, and speaking by infected people. Airborne transmission of COVID-19 is also possible in a confined place in the immediate environment of the infected person. Present study investigates the effectiveness of conditioned air released from air-conditioning machines to mix with aerosol sanitizer to reach every point of the space of the isolation room so as to kill the COVID-19 virus which will help to protect the lives of doctors, nurses and health care workers. In order to numerically model the laminar-transitional flows, transition SST k-e model, which involves four transport equations are employed in the current study. It is found from the analysis that high turbulent fields generated inside the isolation room may be an effective way of distributing sanitizer in entire volume of isolation room to kill the COVID-19 virus.

TL;DR: Simulation results justify that the proposed FLEC scheme outperforms over LEACH, DEEC, and LEACH-Fuzzy protocols.
Abstract: In recent trends, wireless sensor networks (WSNs) are mostly used for a number of applications where conventional networks are infeasible. To perform WSN operation, a number of sensors are deployed in desired network cross-section. Since sensors are embedded with limited resources, it has the limitation while using sensor node’s battery power. Clustering schemes are one of them which can utilize sensor’s power effectively in WSNs. In this paper, a Fuzzy Logic based Effective Clustering (FLEC) of Homogeneous Wireless Sensor Networks for Mobile Sink has been introduced. The problem associated with existing protocol, A Fuzzy logic based Clustering Algorithm for WSN to extend the Network Lifetime (LEACH-Fuzzy), is resolved in FLEC by utilizing the concept of average energy based probability and average threshold for appropriate cluster heads (CHs) selection. In addition, average energy of CHs has been also included in Fuzzy descriptors to make proper super cluster head (SCH) election among CHs. Simulation results justify that the proposed FLEC scheme outperforms over LEACH, DEEC, and LEACH-Fuzzy protocols.
