Thermal decomposition, or thermolysis, is a chemical decomposition caused by heat. The decomposition temperature of a substance is the temperature at which the substance chemically decomposes.
The reaction is usually endothermic as heat is required to break chemical bonds in the compound undergoing decomposition. If decomposition is sufficiently exothermic, a positive feedback loop is created producing thermal runaway and possibly an explosion.

He discussed the concept of quality improvement, emphasizing its applicability to various aspects of life, including personal, project, and program improvements. He defined quality as doing the right thing at the right time in the right way to achieve the best possible results and discussed the concept of the "gap" between what we know and what we do, and how this gap represents the areas we need to improve. He explained the scientific approach to quality improvement, which involves systematic performance analysis, testing and learning, and implementing change ideas. He also highlighted the importance of client focus and a team approach to quality improvement.
2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.
Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

As part of CIE’s continual commitment to maintaining best practice in assessment, CIE uses
different variants of some question papers for our most popular assessments with large and
widespread candidature. The question papers are closely related and the relationships between
them have been thoroughly established using our assessment expertise. All versions of the
paper give assessment of equal standard.
The content assessed by the examination papers and the type of questions is unchanged.
This change means that for this component there are now two variant Question Papers, Mark
Schemes and Principal Examiner’s Reports where previously there was only one. For any
individual country, it is intended that only one variant is used. This document contains both
variants which will give all Centres access to even more past examination material than is usually
the case.
The diagram shows the relationship between the Question Papers, Mark Schemes and Principal
Examiners’ Reports that are available.

Who can I contact for further information on these changes?
Please direct any questions about this to CIE’s Customer Services team at:
international@cie.org.uk
The titles for the variant items should correspond with the table above, so that at the top of the
first page of the relevant part of the document and on the header, it has the words:
•
First variant Question Paper / Mark Scheme / Principal Examiner’s Report
•
Second variant Question Paper / Mark Scheme / Principal Examiner’s Report
or
as appropriate.
