The present invention relates to a method for controlling a process for polymerisation of an olefin and in particular to a method for controlling a process for polymerising at least one olefin in a reaction zone said process comprising in the reaction zone a reaction

2007/3/7A quantitative RT real-time PCR method was developed for the detection and quantification of Tomato mosaic virus (ToMV) in irrigation waters These have rarely been monitored for the presence of plant pathogenic viruses mostly due to the lack of efficient and sensitive detection methods The newly developed method presented here offers a novel approach in monitoring the health status of

Introduction Explosives propellants and gun powders are often classed as highly energetic materials1 and are a special subset of thermal analysis Differential Scanning Calorimetry (DSC) is normally used to study these materials 2 In this note we investigate the application of HyperDSC

crystal defects and production of amorphous material during formulation 22 The relative determination of the amorphous particle sizes based on this reduction of relaxation time is described in ref 23 The authors however note that the method is unable to provide

It should be noted that the latter method only worked for amorphous P3HB These two publications did not state any limits of detection in their methods however the methods were optimised for the determination of P3HB in cells and it is not clear if they would work for the determination

This article describes the development of an analytical method to measure respirable crystalline silica (RCS) collected on filters by a miniature sampler placed behind respirators worn by workers to evaluate their 'true' exposure Test samples were prepared by

A proper development of an analytical method for the determination of amorphous content need several steps The first step is the obtention of the amorphous form It is very important to obtain a amorphous sample in order to determine properly the energy of crystallization

The aim here is to investigate this loss of contrast as a function of image spatial frequency using high resolution images of amorphous carbon It seems that experimental images of amorphous carbon have an unexpectedly high contrast for the low spatial-1

The present invention relates to a method for controlling a process for polymerisation of an olefin and in particular to a method for controlling a process for polymerising at least one olefin in a reaction zone said process comprising in the reaction zone a reaction

Figure 4 2 Top: DSC scans showing idealized profiles for glass transitions and melting temperatures Bottom: Experimental DSC curves for (a) an amorphous polymer and (b) a polymer with both a glass transition and a melting transition A related technique is differential thermal analysis (DTA) which uses similar principles except that instead of current flow the instrument measures the

The present invention relates to a method for controlling a process for polymerisation of an olefin and in particular to a method for controlling a process for polymerising at least one olefin in a reaction zone said process comprising in the reaction zone a reaction

Item 3 Does the molecule display any amorphous character? Note - a qualitative method would be needed to make this determination Quantitative (LoQ) amorphousness method is not required It is recommended to consider (based on project risk assessments) if

2008/7/1Consequently determination of wax content in crude oils residues or bitumens is always test-method related For example the amount of materials which crystallize on cooling as determined by differential scanning calorimetry (DSC) may be used as a measure of wax content [12] [13] [14]

The principle of time-temperature superposition requires the assumption of thermorheologically simple behavior (all curves have the same characteristic time variation law with temperature) From an initial spectral window [ω 1 ω 2] and a series of isotherms in this window we can calculate the master curves of a material which extends over a broader frequency range

The Rietveld method needs an internal standard to quantify minerals in the presence of a significant amorphous component An XRD external standard method was used to measure a proportion of one of the mineral components to act as an internal standard for the samples measured in this study
