Determination of Vanillin and its Adulterants in Consumer Ice cream using High Pressure Liquid Chromatography

AbstractThe paper focuses on the determination of the concentration of vanillin in six types of ice creams purchased from supermarkets Aldi and Sainsbury’s. Similar areas of research haven’t calculated the extraction efficiencies of their proposed methods. In addition to there being no extensive attempts to determine if any adulterants within the selected vanilla ice creams are present. 

Investigating the Synthesis of Imidazolium Salts and their Coordination to a Nickel Metal Centre

This manuscript contains an insight into the mechanisms of inorganic carbene chemistry; synthesis of imidazolium salts from its precursors to using computational chemistry to calculate their quantum mechanical properties. As well as an attempt to deprotonate the iPr imidazolium salt and coordinating the carbene to a standard but labile Ni(0) precursor. The yield of iPr was optimised following the analysis of experimental data of iMes, iXy and Cy salts. The H...

Diagnosis of Pre- and Post-treatment of Echinococcus granulosus with Counter current Immune Electrophoresis and Bacterial Co-agglutination

AbstractObjectives: Echinococcosis is a cyclozoonotic disease caused by E. granulosus. The canine mainly the dog represents the definitive host and immunity plays an important role in the control of the disease. This study was aimed to detect Echinococcus granulosus B-antibody for Dot-ELISA and antigen for counter-current immune electrophoresis (CIEP) and bacterial co-agglutination assay (Co-A). Methods: Follow-up of 23 surgical and chemotherapy patients from different hospitals of Kh...

Design and Implementation of Fake Product Review Monitoring System

The existence of fake product can directly harm a company's growth as well as consumers. Various organizations have been using many initiatives and modern technology to prevent counterfeit goods. But the company that manufactures a real product have introduced many modern technologies such as barcode and QR code. Fake item producers can go to the extent of even building barcodes (existing system) for their products so that when scanned, the result will show the existence of the product....

Design and Implementation of Electronic File Management System for Nigeria National Law Drug Enforcement Agency (NDLEA)

In the operation of Nigeria National Drug Law Enforcement Agency (NDLEA) crime cases are documented on paper documents which has unavoidably increased the amount of paper documents in the office and which can be easily destroyed by water spillage and fire hazards. However, the electronic form of the documentation has the potentials of eliminating the above listed problems of the manual documentation. The aim of this study is to design an electronic file document management system for t...

Usefulness of Deep Web and Prospects for Web Hidden Content

Deep web content includes any content that its owners have blocked web search engines and individual accessing such as medical records, fee-based content, membership websites, and confidential corporate web pages. Most people access Web contents with surface search engines and most of the Web contents are not accessible through surface search engines such as google. A complete approach to conducting research on the Web incorporates using surface search engines and deep web databases. It...

Design and Implementation of Computerised Snooker Game

Computer games have become a common form of entertainment in the 21st century and fast advancement in computer technology and internet speed have helped entertainment software developers to create graphical games that keep a variety of players’ interest. The emergence of artificial intelligence systems has evolved computer gaming technology in new and profound ways. Artificial intelligence provides the illusion of intelligence in the behaviour of Non-Playable-Characters. The aim of t...

Estimation Of Contralateral Breast Dose For Tangential Breast Irradiation Using Gafchromic Film Ebt2

ABSTRACT The dose to the contralateral breast for tangential breast irradiation has been estimated using Gafchromic films EBT2. The data collected consisted of measurements taken with anthropomorphic female Rando phantom. The EBT2 films were scanned and read using ScanMaker 9800XL plus and ImageJ software. A calibration curve was constructed using fourth – order polynomial fit to the data and a calibration equation was obtained from the graph which was used to convert the grey values ...

Quality Control And Dosimetry Of A Wooden Couch Top For Megavoltage External Beam Radiotherapy.

ABSTRACT  The purpose of this study was to determine an appropriate locally fabricated wood sample that could be used to replace the wire mesh incorporated at the treatment area of EBRT couch top to circumvent dose discrepancies associated with the sagging effect of the wire mesh as a result of prolonged use. Linear attenuation coefficient and transmission factor were determined at three stipulated field sizes (5cm x 5cm, 10cm x 10cm,15cm x 15cm) and two treatment depths of 0.5...

Effect of Drying on Chemical Constituents of Peel Essential Oils of Cleopatra Mandarin (L) Growth in the North Central of Nigeria

ABSTRACT: In this study, the oil extracts from fresh and dried peels of Cleopatra mandarin were isolated and characterized via GC-MS technique. Also the study established both quantitative and qualitative variation in chemical constituents of the essential oils of Cleopatra mandarin (L) cultivated in the North central of Nigeria. Fresh and dried pulverized peels of Cleopatra mandarin (500g) were separately hydro distilled and afforded oil in the range 0.2- 0.8%(w/w) respectively. GC/MS a...
