Practices in Planning, Design and Construction of Head Race Tunnel of a Hydro...Mohit Shukla
This paper has been selected for oral presentation as well as inclusion in the conference proceedings of the ICCCGE 2016 : 18th International Conference on Civil,Construction and Geological Engineering held in Toronto, Canada during June,
13-14, 2016. This paper was also able to find a position in the international conference of Dams and Hydropower held at Laos in May 2016.
I hold Doctor of Philosophy (Ph.D.) Physics of Universiti Teknologi Malaysia with specialization in environmental impact assessments. My area of research has been in the fields of radiation assessments, groundwater pollution evaluation, remediation and radiological risk forensics which represent one of the main activities. The effort in these fields was clearly noticed due to the presence of necessary scientific contributions in radiation dose assessments, groundwater monitoring, contamination channels, and remediation of radiotoxicity risks. The excellence of these inputs has provided a baseline for civil engineers and water resources managements on safer areas to drill boreholes for quality and consumable groundwater-based drinking, free from radionuclides. My research innovation has contributed greatly in providing solutions to many complicated groundwater and environmental problems which have been recorded as outstanding discoveries to the readers in scientific community by publishing all the novelties and scientific facts in high quality scholarly Journals guided by Thompson Reuters Journal Citation Reports (ISI-Web of Knowledge). Most of the discoveries have equally shared in International conferences in Hungary, Singapore and Malaysia with the proceedings published in ISI and Scopus indexed Journals. In addition, some of the scientific contributions yielded awards from International Doctoral Fellowship through Universiti Teknologi Malaysia that covered tuition fee and other benefits during my doctoral programme

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.

National University of
Malaysia
• Architect
– Rock is a type of building material, dimension stone
• Engineer
– Rock as a hard or brittle material that requires
BLASTING to excavate.
– A permanent, durable material for erosion control
or engineering uses.
• Geologist
– Rock is an earth material produced by the rock
forming processes; OR
– Rocks are natural earth materials composed of
aggregates of one or more minerals

• SIX parameters are required:
1. Uniaxial compressive strength (JA1)
2. RQD (JA2)
3. Discontinuity spacing (JA3)
4. Conditions of the discontinuities (JA4)
5. Groundwater (flow and general conditions) (JA5)
6. Rating adjustment for discontinuity orientations (JB)
• Based on ratings (total of 6 ratings)
• Total ratings (0-100) will give rock mass classes (I to V).

An engineering geologist knows a dam site better !!
39. National University of
Malaysia
• “this substrate was totally inappropriate
for a dam footing, and failure of
fractured and weathered conglomerate
was the major cause of the dam failure”.
• “Don’t blame anyone else, you just
fasten it on me. If there was an error in
human judgment, I was the human.”
(William Mulholland, dam’s chief engineer & architect).
