Abstract: The recommendation of Polish PN B-03002norm shows a need of quality control of wallelements production, and classified them as elements of category I or II. This classificationis decided in institution of quality control which should provide straight lines diagnostic tools. Requirement of this norm establishing the partial coefficients of wall safety, of wall treats to settlement the ...

Introduction: Pallasites are long thought to represent a metallic core-silicate mantle boundary, where the IIIAB irons are linked to the crystallization history of the metallic fraction, and the HED meteorites may be linked to the silicate fraction [1,2,3]. However, measurement of trace elements in individual metallic and silicate phases is necessary in order to fully understand the petrogeneti...

Geochemical study of a 3.55 m long lake sediment core from the Badanital Lake (Garhwal Himalaya) reveals Late Holocene centennial-scale climatic changes. The ecosystem of the tectonically formed lake seems to be controlled by natural and anthropogenic factors. The imprints of four major global events, e.g. 4.2 ka event, Medieval Warm Period (MWP), Little Ice Age (LIA) and modern warming are obs...

The objective of this research was to assess the effects several irrigation solutions (ISOLs) on two major (P and Ca) some minor (Fe, Zn, Sr) elements multi-root canals radicular dentin in upper premolar teeth using X-ray fluorescence analysis (XRF). Powder fifty specimens were prepared divided into five groups based treatments with different single combined ISOLs. These were: G1-distilled wate...

Zinc based alloys have recently attracted great attention as promising biodegradable metals. Zinc exhibits moderate degradation rates in biological fluid and the zinc releases during the degradation process is considered safe to human systems. However, these materials exhibit critical limitations in terms of mechanical properties for medical applications. Adding alloying elements as well as gra...

education and edification has always been one of the major concerns of mankind and has occupied his mind. undoubtedly, providing successful models is the basic needs of the parents and educators in this field. concentrating on educational approaches has an important place in edifiying issues; since it shows the process of edifiying.the purpose of this research is introducing the fundamentals of...

The detoxification of crops grown in Cadmium (Cd)-contaminated acid soil has been widely studied, but for contaminated alkaline soil, there is still inadequate research or information. In order to investigate the effects calcium and sulfur fertilizers, accompanied by different side elements, on growth Cd uptake Spinacia oleracea Cd-contaminated plants were subjected five treatments, including s...

Laser induced breakdown spectroscopy (LIBS) has become a powerful tool for the direct analysis of a large variety of materials in order to provide qualitative and/or quantitative information. However, there is a lack of information for LIBS analysis of agricultural products. In this work a LIBS system has been designed for the discrimination of Ca, Cu, Fe, and Na elements in Gannan Navel orange...

  Background :Highserum level of cancer antigen 15.3 (CA15.3) has been reported in some malignant and nonmalignant conditions including thalassemia major which could have been resulted from ineffective erythropoiesis. We aimed to evaluate the serum level of CA15.3 in carriers of beta-thalassemia by comparing them with cancer patients and healthy individuals.   Methods : This cross-sectional stu...

in this study, laser induced breakdown spectroscopy (libs) is used for qualitative analysis of healthy and carious teeth. the technique of laser ablation is receiving increasing attention for applications in dentistry, specifically for the treatment of teeth such as drilling of micro-holes and plaque removal. in the process of ablation a luminous micro-plasma is normally generated which may be ...
