Mapping of soil micronutrient variability is critical for improving agronomic biofortification. This study used 1778 surface samples collected from four agro-climatic regions the Indo-Gangetic Plain India to produce digital maps available Zn, Cu, Fe, and Mn using 52 environmental covariates at a resolution 150 m. The prediction accuracy was compared 14 machine learning approaches their ensemble model. hybrid model outperformed all base learners subsequently producing maps. All micronutrients...
With the major application of MMCs, it is thus necessary to develop an appropriate technology for their efficient machining. Milling most common and versatile among different machining processes, characterized by extensive range metal cutting capacity that places in a central role manufacturing industries. In present study attempt has been made find out optimal level process parameters CNC milling Al–4.5%Cu–TiC matrix composites using grey-fuzzy algorithm. Taguchi's L25 orthogonal array...
Background: Deep vein thrombosis (DVT) is a serious complication in stroke patients and may lead to the devastating consequences of pulmonary embolism. The risk factors for DVT acute are advanced age, high National Institute Health Stroke Scale (NIHSS) score, hemiparesis, immobility, female gender, atrial fibrillation. present study aimed at identifying prevalence patients. Methods: This was prospective cross sectional conducted Dhaka Medical College Hospital from January 2022 December 2023....
Objective Growth failure is an often overlooked complication of juvenile dermatomyositis (JDMS) hence, the present study analyses auxological status adolescent JDMS patients. Methods Sixty serial observations with respect to height, weight, and skinfold thicknesses were made on 35 children aged 10 17 years in Laboratory/Clinic Department following a mixed-longitudinal growth research design. Information regard disease duration activity (MMT-8 score) was recorded. Results The mean height...
A field experiment was conducted at Bidhan Chandra Krishi Viswavidyalaya, Nadia, West Bengal to assess the productivity, profitability, and resource efficiency of different cropping systems on broad bed furrow (BBF) over low land traditional rice-rice system. Five viz. T1: elephant foot yam-brinjal (BB): kharif rice+fishsummer rice (F), T2: ridge gourd-potato-pumpkin rice+fish- summer T3: okra-bottle gourdbasella T4: yam–marigold T5: maize- brinjal-greengram(BB):kharif (F) were assessed...
An artificial neural network model of 'Feed Forward Back Propagation' type is developed for the analysis and prediction surface roughness, relationship between cutting process parameters Al-4.5Cu-1.5TiC Metal Matrix Composites. The effect namely, Cutting speed, feed, depth cut upon responses like: roughness parameter Ra, Rz Rt MMC are analyzed during this investigation. Experiments have been carried out as per Taguchi's L25 orthogonal array with five levels defined each factors developing...
We analyzed data from a long-term rice–wheat cropping sequence to evaluate the effects of integrated nutrient management (INM) on yield trends and sustainability, balance soil fertility system. After 30th cycle, grain both crops significantly declined under control highest rice wheat yields were obtained when 50% N supplied through green manure farm yard manure, respectively. The magnitude slope INM was found considerably higher than 100% recommended fertilizer (RDF). Sustainable index (SYI)...
Phosphate reactions in the soil have important implications for crop growth and its nutrition to plants. Using a 40 years old long-term fertility experiment, we studied fate of different sources applied P into wheat calcareous soils pearl millet-wheat cropping system during rabi 2009 2010. Results showed that water soluble phosphatic fertilizers (Single super phosphate, Diammonium Urea ammonium phosphate) were found superior over partially (nitrophosphate) mineral acid (RP) terms grain yield...
In this study, the suitability of sludges produced in Kolkata, India for their agricultural usage has been assessed by analyzing plant nutrients availability, heavy metals loads, and mobility, terms rate release potential negative effect on soil plants using sequential chemical extraction procedures.Results indicated that sludge at different sewage treatment (STPs) Kolkata were rich organic C (9.75-15.88%)and major mainly N (2.05-3.87%)and P (1.62-2.47%);but K content (0.98-1.96%) was much...
In the present investigation, an in-situ multi-component reinforced aluminium copper alloy based metal matrix composite was fabricated by flux assisted synthesis (FAS) technique. It found from optical microscopy analysis that TiC particles are formed in composite. Further research investigates feasibility and dry machining characteristics of Al–4.5%Cu/5TiC CNC milling machine using uncoated solid carbide end mill cutter. The effect parameters such as feed, cutting speed, depth cut on...
In this article, a grey–fuzzy-based algorithm with the Taguchi method is proposed to find optimal process parameters’ setting for submerged arc welding of AISI 1518 grade steel on multiple performance characteristics such as tensile stress, toughness and hardness weldment. Various parameters, wire feed rate, stick out traverse speed process, were exposed by investigation. The algorithm, coupling grey relational analysis fuzzy logic, obtains grey–fuzzy reasoning evaluate according coefficient...
