This is a presentation by Dada Robert in a Your Skill Boost masterclass organised by the Excellence Foundation for South Sudan (EFSS) on Saturday, the 25th and Sunday, the 26th of May 2024.
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.

How to Make a Field invisible in Odoo 17Celine George
It is possible to hide or invisible some fields in odoo. Commonly using “invisible” attribute in the field definition to invisible the fields. This slide will show how to make a field invisible in odoo 17.
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.

Decreased irritation of gingival

Absence of interproximal space after
the completion of treatment.

5. Benefits of Bonding
PRACTITIONER:
eliminates pre-treatment separation
of teeth & needless to mention it also
greatly decreases chair side time.
direct bonding makes it easier to
detect & treat dental caries

6. ADHESION
“The state in which two surfaces are
held together by interfacial forces
which may consist of valence forces
or interlocking forces or both”
www.indiandentalacademy.com
7. ADHESIVE
“ is a material frequently a viscous fluid that
joins two surfaces together and solidifies
and therefore is able to transfer a load from
one surface to the other.
ADHEREND
Material to which an adhesive is
applied is called Adherend
www.indiandentalacademy.com
8. SURFACE WETTING & CONTACT ANGLE
“WETTING” use a fluid that will flow and “wet” an
adherend
“CONTACT ANGLE” which is nothing but an angle
formed by the adhesive with the adherend at
their interface.
IMPORTANCE
The smaller the contact angle, the better able,
is the adhesive to fill in irregularities in the
surface of the adherend.
www.indiandentalacademy.com
10. MECHANICAL :

IRREGULARITIES IN THE SURFACE OF
THE ADHEREND.
ADSORPTION :
CHEMICAL BONDING BETWEEN THE
ADHESIVE AND ADHEREND

11. ELECTROSTATIC:
THERE IS AN ELECTRICAL DOUBLE
LAYER AT THE INTERFACE OF A
METAL AND POLYMER THAT IS PART
OF THE TOTAL ADHESIVE SYSTEM
DIFFUSION :
INTERLOCKING BETWEEN MOBILE
MOLECULES, SUCH AS THE ADHESION
OF TWO POLYMERS THROUGH
DIFFUSION OF POLYMER CHAIN ENDS
ACROSS AN INTERFACE.
www.indiandentalacademy.com
12. Requirements for adhesive
systems
Wetting: An adhesive must give
good wetting of the adherend.
Thickness: Too great thickness
can lead to poor bond strength.
Strength: of the set adhesive
must be taken into consideration.www.indiandentalacademy.com
13. Viscosity: The adhesive should
have a suitable viscosity to enable
it to flow readily over the surface of
adherend
Dimensional Stability: The setting
time of the adhesive should occur
without excessive dimensional
changes i.e.., little expansion or
contraction.

52. Setting Reaction: The hydrogen ions of the acid attack
the glass particles in the presence of water releasing
calcium, strontium, and aluminium ions. The metal ions
combine with the carboxylic group of the polyacid to
form the polyacid salts matrix and the glass surface is
changed to a silica hydrogel.

63. Current categories of Adhesive bonding
According to Howard E. Srassler
(Compendium - June 2003 )
1.Total etch adhesive bonding
2. Self – etch adhesive bonding
www.indiandentalacademy.com
65. 1)Cleansing
2)Enamel conditioning or acid etching
3)Priming
4)Bonding
Bonding or adhesion to the
enamel is done in the
following procedure .
www.indiandentalacademy.com
66. Pre-treatment
Cleansing Improves wetting
Acid etching Improves adhesion
micromechanical retention.
Pre-treatment is necessary as mouth is
complicated by saliva ,acquired pellicle ,
different organic and inorganic
components of enamel and dentin.
www.indiandentalacademy.com
67. Salivary pellicle
When a tooth is cleaned in situ,
salivary proteins and glycoproteins with
a strong affinity for enamel very quickly
adsorb to the tooth surface and form a
very thin layer called salivary pellicle.
www.indiandentalacademy.com
68. CLEANSING
Removal of salivary pellicle &
contaminants
Material used – Pumice
Improves wetting
www.indiandentalacademy.com
81. Etch and deposit the primer
simultaneously
With this procedural sequence , it is
likely that the under filling of the
inorganic depleted zones will not
occur.
1 unit contains enough material for one
arch.
SELF ETCHING PRIMERS
www.indiandentalacademy.com
82. Etching depth & the resin
penetration depth are identical
Can be used for metal & ceramic
brackets.
It is a hydrophilic primer-
tolerates both moist & wet
conditions.
www.indiandentalacademy.com
94. Moisture Insensitive Primer
Bonding can be done in the presence of
Moist environment.
Requires moisture for the initiation of
polymerization.

Hydrophilic primer – from 3rd generation
www.indiandentalacademy.com
95. Why Moisture control is
important?
Surface energy reduced – less favourable
for bonding
Porosities are plugged – reduced no of
tags
Difficult anatomical areas

( main Hydrophilic component )
- CDMA – Citric acid
( allows greater cross linking )
- GDMA – Diluent + hydrophilic monomer
/ Same function as CDMA
/ The Hydrophilic monomer takes
Oral fluid & so fluoride uptake
- Acidic Co-polymer
/ Greater cross linkingwww.indiandentalacademy.com

( Water normally interferes with
adhesive if not removed.
But in Transbond, Water induces
Partial ionization of Carboxyl groups
& an inert dilution effect without
Activating any setting mechanism )

Wet Conditions
Higher bond strength with MIP in
1 & 24 hours

130. ADVANTAGES
1)Esthetically superior

Less discomfort for the patient
Arch length is not increased by band
material and no band spaces to close
at the end of treatment .
Better access for cleaning
Mesiodistal enamel reduction is
possible during treatment.www.indiandentalacademy.com
131. Disadvantages
1)However a bonded bracket has a weaker
attachment than a cemented band .
2)Better oral hygiene is not guaranteed
especially if excess adhesive extends
beyond the bracket base.
3)Rebonding a loose bracket requires more
preparation than rebonding a loose band
