In recent couple of years, the crop growth and yield have been decreased due to various abiotic stresses. It has been revealed that applying rhizobacterial strains promote plant development and increase crop productivity under stress conditions. The goal of present investigation was to identify psychrotrophic bacterial strains from rhizosphere of mustard that could alleviate cold stress and enhancing mustard growth. A total of 88 rhizobacterial strains were isolated from mustard and screened for low temperature, 1-aminocyclopropane-1-carboxylate deaminase (ACC) and other plant growth promoting (PGP) attributes. The strain EU-MRN-53 showed efficient psychrotrophic ACC deaminase producer (784 ± 1.08 nmol α-ketobutyrate mg protein<sup>− 1</sup> h<sup>− 1</sup>) along with other PGP attributes and identified as <i>Planococcus donghaensis</i> using 16 S rRNA gene sequencing. To the best of knowledge, the present study is the first report on ACC deaminase producing novel psychrotrophic bacterium <i>Planococcus donghaensis</i> (EU-MRN-53) for growth enhancement of mustard. Moreover, the inoculated psychrotrophic <i>Planococcus donghaensis</i> strain also aided in inducing stress response in mustard by improving growth and photosynthesis parameters. The efficient strain <i>Planococcus donghaensis</i> (EU-MRN-53) could be used as bioinoculants for horticultural crop growing in mountainous regions.</p></div>","PeriodicalId":717,"journal":{"name":"National Academy Science Letters","volume":"49 4","pages":"491 - 494"},"PeriodicalIF":1.1,"publicationDate":"2025-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148695660","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Aiming at the characteristics of small size, small radar cross-section, and complex use environment of UAV, this paper designs a UAV classification mode based on a convolutional neural network (CNN). Firstly, the one-dimensional RCS sequence is converted into a two-dimensional image representation. In the experiment, four different conversion models are used. The conversion can enrich the amount of information in the original data, and the differences between different categories can be highlighted to obtain better recognition accuracy. Then it is imported into the improved CNN (UAVsNet) for recognition. Adding an attention module and modifying the classification module improves the recognition accuracy of the network. The experimental results show that UAVsNet has the recognition accuracy of 96.32% on the GASF dataset, which is 0.46–4.63% higher than other datasets.

This study examines the impact of crop establishment methods (MTPs) and integrated nitrogen management practices (INMPs) on rice yield, profitability, and soil health in the region. The experiment was set up in a split plot design with three replications. The treatments included three MTPs in the main plot and seven NMPs in the subplot. The results showed that system of rice intensification (MTP3) exhibited approximately 14.6% higher yield as compared to other treatment.

In case of INMPs, treatment INMP4 (75% N inorganic + 25% N through poultry manure (PM) + <i>Azospirillum</i>) recorded the significant highest grain yield (5.10 Mg ha<sup>− 1</sup>) as compared to the other treatments. INMP4 also recorded the maximum net return (1213 USD ha<sup>− 1</sup>) and B: C ratio (1.89) indicating its significant economic superiority compared to other treatments. The soil exhibited the significant approximately 10% higher available nutrients (NPK) after two years of cropping under the INMP4 followedby INMP2 (75% N inorganic + 25% N through PM) and surpassed those of all other treatments by a significant margin.

The severity of this risk depends on various factors, including water conductivity, system voltage, distance, nozzle geometry, stream pattern, and water pressure. To enhance firefighter safety during PV fire suppression operations, an experiment was conducted to determine a safe distance for hose reel use by varying nozzle diameters, pressure, and distance. The research aims to determine specific distances that firefighters should maintain to minimize the risk of electric shock when suppressing fires involving PV systems. The results indicated that increasing water pressure reduces leakage current, assuming all other parameters remain constant. Additionally, leakage current decreases as the distance between the nozzle and the target electrode increases. Conversely, a larger nozzle diameter leads to a higher leakage current. For a 50 V DC supply, with a nozzle outlet diameter of 9 mm and water pressure of 1.2 bar, the safe distance for fire suppression was identified as 88 cm. With a nozzle outlet diameter of 5 mm, the safe distance increased to 98 cm. These findings offer valuable insights to mitigate electric shock risks for firefighters involved in PV fire suppression operations.</p></div>","PeriodicalId":717,"journal":{"name":"National Academy Science Letters","volume":"49 4","pages":"601 - 606"},"PeriodicalIF":1.1,"publicationDate":"2025-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148695627","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
