    Abstract: Pharmaceuticals and personal care products (PPCPs) are generally neither totally removed by sewage treatment nor completely destroyed in the environment. Metformin (MET) and triclosan (TRI) are two compounds in PPCPs that have the potential to be environmental pollutants. This research aimed to determine MET and TRI in sewage sludge using a liquid chromatograph-mass spectrometer (LCMS-8040) and a sewage sludge extraction method. The Milli-Q water and sewage sludge were also tested at three different MET and TRI concentrations (0.01, 0.02, and 0.03 mg L-1). As a result, the corresponding recoveries of MET and TRI in both matrixes ranged from 85.93 to 116.10 per cent and 90.50 to 116.30 per cent (n = 7, RSD 〈 10%). Then, the limit of detection (LOD) and the limit of quantification (LOQ) for MET and TRI were found to be 0.005 and 0.01 mg L-1. The amounts of MET and TRI in the sewage sludge samples from the Ukkadam sewage treatment plant (USTP), Coimbatore, ranged from BDL to 0.0587 mg L-1 and 0.0719 to 0.1851 mg L-1, respectively. Consequently, the amounts of MET and TRI in the sewage sludge samples from the Tamil Nadu Agricultural University sewage treatment plant (TSTP), Coimbatore, ranged from BDL to 0.0227 mg L-1 and 0.0393 to 0.1296 mg L-1, respectively. This exclusive use of the highly sensitive LCMS-8040 consumes less time than other analytical methods for measuring the amount of MET and TRI in sewage sludge by overcoming the risk of chemical degradation.

    Abstract: Drip Design Check (DDC) is a powerful software solution designed to assist irrigation system designers in evaluating the effectiveness of their drip irrigation designs for non-uniform slope conditions. The software makes use of recent developments in drip design methods as well as the advancements in software development methodologies for simulating and optimizing the design of laterals. The software features an easy-to-use interface that allows users to input key design parameters, including slope details, discharge rate of drippers, length of lateral, spacing between drippers and pressure head at the inlet of lateral. The software calculates relative pressure head variation (vh) and pressure head values at each outlet. The software evaluates the goodness of the design based on the allowable relative pressure head variation. Simulation of lateral also considers dripper connection losses. Variations in lateral and dripper configurations are handled by the software in line with the intuition of the user’s perceptions. Hence, data input is simple and easy. The software can be used to analyse numerous design alternatives and to identify the most appropriate design. DDC has undergone several tests using different typical sample data and hence its accuracy and reliability are more. Demonstrations were conducted for designers to assess the user friendliness of the drip simulation software, and we received favourable feedback from them. In summary, Drip Design Check is a useful and reliable tool for the irrigation industry to check the goodness of lateral design.

    Abstract: This study aimed at utilizing unmanned aerial vehicle in place of a conventional hand sprayer for the smart delivery of agricultural inputs especially crop nutrients. A field experiment was conducted in the farms of Agricultural Research Station, Bhavanisagar, Tamil Nadu Agricultural University. There were nine treatments which were replicated thrice in a randomized block design. The treatments include NPK 19:19:19 along with liquid micronutrient, humic acid, and TNAU Maize maxim at two intervals viz., 50% Tasselling, and Cob filling stage. These nutrients were applied as foliar spray through battery operated and fuel operated drones and were compared with knapsack hand sprayer. Biometric observations such as plant height, leaf area, dry matter accumulation and yield parameters such as cob yield and number of grains per cob were observed during the critical crop growth stages. Foliar application of nutrients through drones had a significant influence on the growth and yield of maize crop. TNAU Maize maxim applied using the fuel-operated drone with an atomizer nozzle (T7) @ 30 lit/ac spray fluid recorded the maximum biometric and yield attributes than other treatments. Improved biometric attributes like plant height of 261.2 cm and 270.32 cm, LAI of 4.14 and 5.15, and DMP of 12354 kg/ha and 18564 kg/ha at 60 DAS and 90 DAS, respectively was recorded with drone spray. It also resulted in a grain and stover yield of 7195 kg/ha and 10942 kg/ha, respectively than hand sprayer.

    Abstract: The proportion of agricultural water consumption is continuously decreasing due to increased competition for water resources by urban, industrial, and agricultural users. Drip irrigation is more efficient in terms of water and energy utilization. These considerations are critical in view of the ongoing struggle for water resources among various consumers due to water scarcity. Some of the most critical criteria in the effective design and maintenance of drip irrigation systems are the shape and size of the volume of wet soil beneath the emitter. Hence several statistical models were constructed in this research to estimate the dimensions of wetting patterns, which are critical for designing an optimal drip irrigation system. The Nash-Sutcliffe efficiency (NSE), coefficient of correlation (CC), and root mean square error (RMSE) criteria were used to assess the models' performance. The results showed that the Polynomial model was the most accurate for horizontal advance, with 0.94, 0.93, and 1.33 (cm) values for CC, NSE, and RMSE, respectively. For vertical advance, the logarithmic model showed 0.96, 0.96, and 0.72 (cm) values for CC, NSE, and RMSE. Thus, in the absence of a wetting pattern and under identical conditions, these models can be utilized to generate synthetic horizontal and vertical advances data.

    Abstract: “CyberCut™” is a testbed for an Internet-based CAD/CAM system. It was specifically designed to be a networked, automated system, with a seamless communication flow from a client-side designer to a server-side machining service. The creation of CyberCut required several new software modules. These include: a) a Web-based design tool in which Design-for-Manufacturing information and machining rules constrain the designer to manufacturable parts; b) a geometric representation called SIF-DSG, for unambiguous communication between the client-side designer and the server-side process planner; c) an automated process planning system with several sub-modules that convert an incoming design to a set of tool-paths for execution on a 3-axis CNC milling machine. Using this software-pipeline, a CyberCut service, modeled on the MOSIS service for VLSI chips, has been now been launched for limited student-use at a group of cooperating universities.
