Introduction: Lentil (Lens culinaris) is a pulse largely consumed in the world, especially in Algeria. This legume can be consumed in different forms (pottage, soup), but also flour can be produced after roasting treatment of the lentils. Resulted flour can be used as a food or ingredient in the formulation of food products. Aims: The main objective of this study is to determine the variation in the main mineral content of lentil flour. The flour was analyzed at its native state (raw), after roasting, raw before addition to yogurt, and roasted after addition in yogurt as a functional ingredient at a rate of 4%. Material and Methods: The lentil flours analysis was carried out by means of Scanning Electron Microscopy (SEM) associated with Dispersive X-ray Energy (EDX) microanalysis (SEM-EDX). Results: The results show that the roasting treatment does not have a marked effect on the mineral content of lentil flours. However, the addition to the yogurt made it possible to raise the mineral content of the raw and roasted lentil flour remarkably. Conclusions: Adding lentil flour to yogurt is an effective way to increase the mineral content of yogurts made from these flours. Keywords: Lens culinaris, flour, roasting, SEM-EDX, mineral.

Abstract Total reflection X-ray fluorescence spectrometry and chemical preconcentration have been applied for multi-elemental analysis of Damascus drinking water. Water was taken directly from taps of several city sectors and analyzed for the following trace elements: Ti, V, Cr, Fe, Co, Ni, Cu, Zn, Se and Pb. The detection limits were found to be in the range of 0.1 to 0.4 µg/L. The mean levels of trace elements in the Damascus drinking water were below the World Health Organization drinking water quality guidelines.

The impetus for this research work arose from alleged signs of Lead (Pb) poisoning from Medicines Sans Frontiers (Doctors without Borders).These poisonings were narrowed down to areas of solid minerals mining and extraction in Northern Nigeria. The aim of this research work is to identify mining Sites with ores having high Pb concentration. Fifteen samples were collected from areas located at approximately latitudes 𝟶𝟶70𝟶8.69𝟶ˈE and longitudes 𝟶90 34ˈ224ˈˈN and interrogated using Proton induced X-ray emission (PIXE) technique for their elemental content. PIXE was chosen because of its sample nondestructive and it does not contaminate the environment. The result obtained varied between 24.3 – 632303.3 ppm. The world Health Organization recommends that sites with Pb concentration above 400 ppm are inimical to human health and ordered that children be evacuated from such areas. Exposure to Pb poisoning may cause anemia, weakness, and Kidney and brain damage; particularly in children.

Background/Aim. The task of a forensic examiner during exhumation of skeletal remains is to calculate antemortem height of a person whose skeletal remains were found. Anthropological investigations which provided formulae for calculating ante-mortem body height date back from XIX or from the first half of XX centuries. The most commonly used formulae are those of Trotter- Gleser, which were used to investigate skeletal remains from the World War II. Those investigations were conducted on skeletal remains of various ages and degrees of decay. Our experience with exhumation have shown that the present formulae do not deliver reliable values of antemortem height. The aim of this study was to investigate if there is a correlation of the length of long bones of leg and forearm with body height within our population and to establish the formulae for calculating ante-mortem body height within our population based on the obtained values. Methods. The lengths of ulna, radius, fibula and tibia were determined precisely by measuring bones on living individuals using a digital X-ray system. The height of individuals whose bones were measured was determined using an anthropometer. Results. The highest degree of correlation between bone length and body height was found for tibia in males (r = 0.859, p < 0.005) and ulna in females (r = 0.679, p < 0.05). We calculated the regression formulae for determination of ante-mortem body height that differ from the current body height formulae. Conclusion. In our population the length of long bones of the forearm and the leg are characterized by various degree of correlation with body height. The formulae that we set, make less distinction between the measured and the calculated body height as compared with the Trotter-Gleser formulae. We do hope that their implementation will facilitate identification of sceletal remains in our population.

Clay is one of the major raw materials in ceramics, paint and paper industries. In this paper, a report is given on the chemical composition of clay deposits in Ilaro and Ikorodu, South West Nigeria and their suitability as raw materials in the above mentioned industries is suggested by comparison of their composition with industry standards. The clay samples were activated with H2SO4 and their moisture content was determined. The mineral content of the clays was determined using atomic absorption spectroscopy, which showed significant presence of Si, Al, Fe, and Ti. The morphology of the clays was studied using scanning electron microscope (SEM/EDX) in combination with X-ray analysis. The investigation revealed the agglomeration of the particles of quartz and rutile on the surface structure of the activated clays. The results obtained from their observed properties and chemical compositions indicate that these clays are suitable for use in the ceramics, paint and paper industries. This proposition is supported by reduction in moisture contents of the activated clay samples from both Ilaro and Ikorodu.Int J Appl Sci Biotechnol, Vol 4(1): 21-26

The “Monetiere” of Florence hosts the most important collection of Etruscan coins in the world. In the framework of the longstanding collaboration between the Monetiere and the Applied Laser and Spectroscopy Laboratory in Pisa, the Etruscan gold coin collection of the museum was studied. The measurements were performed at the Monetiere, using a portable energy-dispersive X-ray fluorescence (XRF) instrument. The quantitative determination of the gold alloys used for the realization of the coins was obtained applying the fundamental parameters method to the XRF spectra; as a result, using the self-organizing maps method, we were able to classify the coins in four main groups. The main parameter determining the classification is the quantity of silver in the alloy. The results obtained shed some light about the origin of the coins under study.
