An Efficient Model for Forest Fire Detection using Deep Convolutional Neural Networks

Forest fires are a significant natural disaster that causes extensive damage to both human and wildlife habitats. Early detection and management of forest fires are critical in preventing potential losses. In recent years, deep learning-based approaches have emerged as promising solutions for forest fire detection. This paper proposes a deep learning-based approach for forest fire detection using SqueezeNet model.The proposed approach utilizes still images captured from forest areas under different weather conditions to classify whether an image contains a fire or not. The models were trained and tested using accuracy, precision, and recall metrics. The experimental results show that SqueezeNet achieve high precision, and recall in detecting forest fires.SqueezeNet is a Convolutional Neural Networks (CNN) architecture designed to reduce the number of parameters and computations required in a deep learning model while maintaining high accuracy in image classification tasks.

A novel seed plants gene regulates oxidative stress tolerance in arabidopsis thaliana

Oxidative stress can lead to plant growth retardation, yield loss, and death. The atr7 mutant of Arabidopsis thaliana exhibits pronounced tolerance to oxidative stress. Using positional cloning, confirmed by knockout and RNA interference (RNAi) lines, we identified the atr7 mutation and revealed that ATR7 is a previously uncharacterized gene with orthologs in other seed plants but with no homology to genes in lower plants, fungi or animals. Expression of ATR7-GFP fusion shows that ATR7 is a nuclear-localized protein. RNA-seq analysis reveals that transcript levels of genes encoding abiotic- and oxidative stress-related transcription factors (DREB19, HSFA2, ZAT10), chromatin remodelers (CHR34), and unknown or uncharacterized proteins (AT5G59390, AT1G30170, AT1G21520) are elevated in atr7. This indicates that atr7 is primed for an upcoming oxidative stress via pathways involving genes of unknown functions. Collectively, the data reveal ATR7 as a novel seed plants-specific nuclear regulator of oxidative stress response

A Sustainable Development Perspective and Evaluating the Impact of Laser Cladding Parameters on Mild Steel

Mild steel is a popular material used in various applications due to its excellent machinability, strength and durability. Mild steel is one of the most affordable materials available, making it an excellent choice for budget-conscious projects. Regrettably, Mild steel is not typically used in some industries due to its low strength-to-weight ratio and limited corrosion resistance. AISI 1020 steel is relatively soft and has limited wear resistance compared to other types of steel, particularly those with higher carbon content. This review paper discusses the profitable and successful approach to enhance the service life and utility of the mild steel machinery components. Various investigators have put their effort into developing different methods to improve the properties of the mild steel components. The laser cladding process is developed by the melting of the preplaced coating layer with the surface of the substrate simultaneously which is able to prevent direct contact with the environment. The present review paper discussed in detail the impact of various parameters of laser cladding process and variation of the coating materials on the surface properties and microstructure of mild steel. Some challenges and remedies are also discussed in the paper. This review paper focused on some potential uses of the laser cladding process in diverse industries

Priming with a seaweed extract strongly improves drought tolerance in arabidopsis

Drought represents a major threat to plants in natural ecosystems and agricultural settings. The biostimulant Super Fifty (SF), produced from the brown alga Ascophyllum nodosum, enables ecologically friendly stress mitigation. We investigated the physiological and whole-genome transcriptome responses of Arabidopsis thaliana to drought stress after a treatment with SF. SF strongly decreased drought-induced damage. Accumulation of reactive oxygen species (ROS), which typically stifle plant growth during drought, was reduced in SF-primed plants. Relative water content remained high in SF-treated plants, whilst ion leakage, a measure of cell damage, was reduced compared to controls. Plant growth requires a functional shoot apical meristem (SAM). Expression of a stress-responsive negative growth regulator, RESPONSIVE TO DESICCATION 26 (RD26), was repressed by SF treatment at the SAM, consistent with the model that SF priming maintains the function of the SAM during drought stress. Accordingly, expression of the cell cycle marker gene HISTONE H4 (HIS4) was maintained at the SAMs of SF-primed plants, revealing active cell cycle progression after SF priming during drought. In accordance with this, CYCP2;1, which promotes meristem cell division, was repressed by drought but enhanced by SF. SF also positively affected stomatal behavior to support the tolerance to drought stress. Collectively, our data show that SF priming mitigates multiple cellular processes that otherwise impair plant growth under drought stress, thereby providing a knowledge basis for future research on crops

Purification and characterization of proline/hydroxyproline-rich glycoprotein from pearl millet coleoptiles infected with downy mildew pathogen Sclerospora graminicola

Hydroxyproline-rich glycoproteins (HRGPs) are important plant cell wall structural components, which are also involved in response to pathogen attack. In pearl millet, deposition and cross-linking of HRGPs in plant cell walls was shown to contribute to the formation of resistance barriers against the phytopathogenic oomycete Sclerospora graminicola. In the present study, the purification and characterization of HRGPs that accumulated in coleoptiles of pearl millet seedlings in response to S. graminicola inoculation has been carried out. Periodic acid Schiff’s staining revealed that the purified protein was a glycoprotein. The protein to carbohydrate ratio was determined to be 95.5:4.5 (w/w). Proline amounted for 20mol of the total amino acids as indicated by amino acid composition analysis. The isolated protein had a pI of 9.8 and was shown to be composed of subunits of 27, 17, and 14kDa. Cross reactivity with the monoclonal antibody MAC 265 and the presence of the signature amino acid sequence, PVYK, strongly suggested to classify the purified glycoprotein as a member of the P/HRGPs class. In the presence of horseradish peroxidase and H2O2 the purified glycoprotein served as a substrate for oxidative cross-linking processes
