Bioethanol is an attractive source of energy when compared to fossil fuel. It renewable and environmentally friendly due its low toxicity biodegradability. The first generation bioethanol derived from limited by the high cost production these crops danger posed food security. This study investigated use wild maerua shrub in comparison cultivated crops. Fermentation was done using Yeasts Y1, Y2 ...

In this present study our aim was to evaluate In vitro antioxidant and free radical scavenging potential of methanolic extracts of Bauhinia variegata Linn. Different parts of Bauhinia variegata like leaves, bark and flowers have free radical scavenging activity by hydroxyl radical scavenging method. All extracts have different level of antioxidant activity. Methanol extracts was found to be goo...

The upward trend of consumption processed food must not dim the demand taking healthy and safe among population. Thus, six popular commercial brands instant mango drinks powder Bangladesh were targeted to investigate some quality parameters (proximate compositions, mineral contents bioactive compounds). Mineral compounds determined by using biochemical analyzer UV-visible spectrophotometer, res...

We discuss two new observational techniques that use observations of the cosmic microwave background (CMB) to place constraints on the mass, distance, and size distribution of small objects in the Kuiper Belt and inner Oort Cloud, collectively known as trans-Neptunian objects (TNOs). The first new technique considers the spectral distortion of the isotropic, ormonopole, CMBbyTNOs that have been...

Abstract New film dosimeters PVA/(DCP/CR) and PVA/(DCP/BPR) have been prepared through the casting method. The colorimetric properties of both films changed from violet to pink green yellow with exposures gamma rays between 0–80 0–40 kGy, respectively. color response was accelerated chloral hydrate half radiation dose 0–20 kGy for systems, UV–visible spectrophotometer shows outstanding stabilit...

In this work, we have developed a versatile three-in-one single beam visible colorimeter for undergraduate laboratory courses. The battery and mains electricity supply (utility power), wired wireless data logging, 3D-printed components are three important highlights of the colorimeter. system is based on low-cost ARDUINO UNO microcontroller can measure absorbance liquid samples in region electr...

AIMS To develop a non-invasive method to demonstrate the presence of haemoglobin and its degradation products in bruises in live human subjects for the purposes of objectively assisting in the determination of the age of a bruise. METHODS The cuvette holder unit of a Cary 100 Bio UV-Visible Spectrophotometer was replaced with the manufacture's fibre optic cable and optical reflectance probe. ...
