Seed varietal purity is vital to establish a uniform plant population. If the seeds are impure, it creates an unhealthy population that brings labor-intensive crop production. In this study, rapid inspection method was established classify paddy seed based on using machine vision technique with multivariate analysis methods. Three varieties of were taken, namely - BR 11, BRRI dhan 28 and 29. The individual image captured RGB camera white LED lighting conditions in laboratory. An processing...

As adulteration of foodstuffs with Sudan dye, especially paprika- and chilli-containing products, has been reported some frequency, this issue become one focal point for addressing food safety. FTIR spectroscopy used extensively as an analytical method quality control safety determination products. Thus, the use rapid dye in paprika powder was investigated study. A net analyte signal (NAS)-based methodology, named HLA/GO (hybrid linear analysis literature), applied to spectral data predict...

Allicin and soluble solid content (SSC) in garlic is the responsible for its pungent flavor odor. However, current conventional methods such as use of high-pressure liquid chromatography a refractometer have critical drawbacks that they are time-consuming, labor-intensive destructive procedures. The present study aimed to predict allicin SSC using hyperspectral imaging combination with variable selection algorithms calibration models.Hyperspectral images 100 cloves were acquired covered two...

In a quantitative assessment of water collected from the midstream Karatoa river in Bangladesh, 31 samples were analyzed to assess heavy metals, major ionic constituents and suitability parameters for irrigation usage. The electrical conductivity all within range 450 1653 ?S cm-1 indicating medium high salinity. Total dissolved solids ranged 247 789 mg L-1 rated as fresh (<1000 L-1). anion chemistry was dominated by HCO3- Cl-, which contributed 66 31%, respectively total anionic mass...

The potential adulteration of foodstuffs has led to increasing concern regarding food safety and security, in particular for powdered products where cheap ground materials or hazardous chemicals can be added increase the quantity powder obtain desired aesthetic quality. Due resulting health threat consumers, development a fast, label-free, non-invasive technique detection over wide range is necessary. We therefore report rapid Raman hyperspectral imaging authenticity analysis. system...

Seed viability is essential to have a homogeneous plant population. The seed industry cannot adopt traditional procedures for evaluation since they are destructive, time-consuming, and need chemicals. This study aimed investigate the potential of combining hyperspectral color image features differentiate viable non-viable paddy seeds. 355 seeds was captured later used examine their viability. An processing algorithm developed extract from images investigated significant differences in...

This study aims to develop an automated image acquisition system for paddy leaves images and processing algorithm estimate the severity level of disease. The were acquired using developed processed MATLAB software. By quantifying total infected leaf area based on pixel counting, calculated percentage a ratio-based method. Through method, achieved range 34% 42% area. In comparison, meter method yielded lower 22% 28% indicates that image-processing approach can capture wider extent infection....

The study was conducted to determine heavy metal contents in industrial wastewater and contaminated soils of Bhaluka, Mymensingh assess their pollution level. A total 9 12 farm soil samples were collected directly from the farmers’ fields Bhaluka area analysed for this study. Considering EC, salinity TDS, 56 89% found problematic long term irrigation. concentration CO3, HCO3 Cl ranged 0.20-1.60, 2.0-11.2 1.30-4.79 me L-1, respectively content Ca, Mg, Na K 16.03-52.10, 4.86-21.87,...

The study was undertaken to evaluate groundwater quality both for drinking and irrigation usage collected from the Sadar upazila of Jamalpur district, Bangladesh. Total 20 samples were whole area analysed various physicochemical parameters following standard protocols at Department Agricultural Chemistry, Bangladesh University, Mymensingh during March December 2017. Concentrations different heavy metal (Fe, Mn, Cu, Pb, Cr, Cd Zn) in measured by an atomic absorption spectrophotometer (AAS)....

1. This study was conducted to develop an efficient technique for separating double-yolked (DY) from single-yolked (SY) light brown broiler eggs with comparable shape and size, that were hard distinguish merely by their external characteristics, using Vis-NIR transmission spectroscopy combined multivariate analysis.2. Spectroscopic (200-900 nm) measured after collecting the eggs, yolk number verified breaking boiling. The absorbance of important spectral wavelengths sensitive amount...

Worldwide prevalence of diabetes mellitus has become an issue great concern in current decades. This life threatening disease is associated with worsening glycemic control and progressive metabolic dysfunctions. Objective: Current study aimed to investigate the effect hydroxychloroquine (HCQ) as adjunct glibenclamide or metformin on alloxan induced diabetic rats. Methods: HCQ was combined separately two conventional anti-diabetic drugs; metformin. At first, (120 mg/kg) rats were treated...
