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 (3.541012 n.cm-2 .s-1 ) and the top (1.931012 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.

The aim is to provide general clinical guidance highly available to health professionals. However, EBM teaching is o en found to be disproportional with incomprehensive description of the method, the critical appraisal found insu cient leading to lack of e ectiveness. Also, if too much attention is solely paid to basic knowledge on clinical epidemiolo-gy, or on critique skill or exploration of medical information from reference materials,..

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.

In Vietnam, there is no complete and systematic research but preliminary research on prosecution of imprisonment execution. In other nations, there are research on the prosecution/supervision of imprisonment execution but they studies on foreign laws and reality. Therefore, this thesis is not duplicated and foreign works as reference materials which contribute to the development of the thesis.

(BQ) This text together with the references supplied, and excellent sources now available on the Internet, should enable the reader to understand the key concepts and arguments. In addition, a simple “Good Science Detection Guide” is included in the appendix to aid in the identification of the good, the bad, pseudoscience and non-science in healthcare writing and research. Summary ideas for critical discussion are also presented at the end of each chapter that may be helpful for those teaching this material.

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.
