English reference materials

Vitamins are essential nutrients commonly found in food products in general and health supplements in particular. In order to accurately evaluate product quality, laboratories need to use reference material in analysis, proficiency assessment, method validation and ensure the validity of the results.

This brief note discusses the search for spirituality in post-modern societies, mainly with reference to the Japanese context. It will become clear that the study of contemporary dynamics needs to take the religious/spiritual aspect into account, by recognizing what is happening on the border between the material and the spiritual world and what needs are being met by the various new spirituality movements.

n this work, some popular analytic formulas such as Maxwell (MA), Mori-Tanaka approximation (MTA), and a recent method, named the Polarization approximation (PA) will be applied to estimate the elastic moduli for some porous media. These approximations are simple and robust but can be lack reliability in many cases. The Hashin-Shtrikman (H-S) bounds do not supply an exact value but a range that has been admitted by researchers in material science. Meanwhile, the effective properties by unit cell method using the finite element method (FEM) are considered accurate.

In this work, a model is delivered, which highlights a simple mathematic relationship between the refractive index of an optical material and its transmittance spectrum measured by Fourier Transform Infrared Spectroscopy. Such model allows determining the refractive index of ceramics fabricated by hot-pressing of MgF2 nanoparticles. The reliability of this method has been verified on a silicon wafer taken as a reference (< 0.5%, discrepancy with data from literature on Si). Our approach can be applied to a variety of promising novel optical materials being developed.

The main purpose of this work is to test the system for both mechanical and analytical reliability. A systematic study has been carried out including measurements for timing parameters of the system and neutron flux at irradiation positions, and the application of this system to determining of Selenium in a number of biological reference materials for validation purpose.

In the case of the irradiation position at the rotary rack of the Dalat Nuclear Research Reactor (DNRR), the difference of thermal neutron flux between the bottom (3.541012 n.cm-2 .s-1 ) and the top (1.931012 n.cm-2 .s-1 ) of the 15 cm aluminum container is up to 45%. Therefore, it is necessary to accurately determine above-mentioned parameters in the sample irradiation position. The present paper deals with the determination of the distribution of thermal neutron flux along the sample irradiation container by using 0.1% Au–Al wire activation technique.

In vitro regeneration through seeds were studied in lime (Citrus aurantifolia) by culturing lime seeds on MS media supplemented with BAP (1, 3 and 5 mg/l), Kinetin (1, 3 and 5 mg/l) and their combination with NAA (0.1, 0.5 and 1 mg/l). In reference to increased germination percentage, mean shoot length, mean number of leaves per explant and mean root length, among BAP and Kinetin concentrations, BAP 3 mg/l was found to be the best treatment. In terms of cytokinins and NAA combine effect, BAP 5 mg/l + NAA 0.5 mg/l and Kinetin 3 mg/l + NAA at 0.1 mg/l were found to be the best combinations.

The aim of this study was to isolate fungi from plastic polluted sites of Patna and to study their ability to degrade LDPE with reference to SEM analysis. The fungi were identified by studying their macroscopic and microscopic characteristics. Penicillium sp. was selected on the basis of the positive screening and was further used to study the degradation of LDPE sheets during a course of 15 and 30 days separately.

The term “push” and “pull” have been used to explain a wide variety of production inventory systems. The distinction refers to a specific attribute, which can be identified by observing the mechanisms for controlling material flow on the shop floor and a specific policy for the management of inventories and production schedules. This paper gives an attempt to compare these systems under their optimal settings under a constraint resource.
