Acetabularia Information For Class 9 .docxvaibhavrinwa19
Acetabularia acetabulum is a single-celled green alga that in its vegetative state is morphologically differentiated into a basal rhizoid and an axially elongated stalk, which bears whorls of branching hairs. The single diploid nucleus resides in the rhizoid.

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.

2. Water's - best for maxillary sinus
(Ethmoids and frontals too far from film)
45
3. Basic Patient Position
The patient sits erect facing the bucky, midsagittal plane
in the midline of the film, coronal plane parallel to the
film interpupillary line parallel to the floor. The chin is
raised to bring the orbital meatal line at 45 degrees to the
film.
In some centers the patient is imaged mouth open to
demonstrate the sphenoid sinuses.
17. enlargement of the adenoids (red arrow)
The white arrow points toenlarged lingual tonsils at
the base of the tongue.
18.
19. Neck lateral veiw
1. Cervical vertebrae
• Erosion of vertebral bodies- No.
• Loss of cervical Lordosis – due to prevertebral muscle
spasm
2. Pre-vertebral soft tissue shadow
• Should be < 2/3 of AP diameter of cervical vertebral
body (c2-6mm, c6-22 mm)
• If > suspect Retropharyngeal abscess
• Look for FB / Air fluid level / Gas shadow
3. Air collumn in trachea
4. Hyoid bone & Laryngeal cartilage ossifications
30. • Radiopaque FB easily seen with xray
• Radiolucent FB (the majority) may have
obliterated bronchial air
column, atelectasis, mediastinal shifts, or air-
trapping in the affected lung
• Inspiratory hypoinflation and expiratory
hyperinflation in hallmark of bronchial FB
• Decubitus films – dependent lung should collapse
but will remain inflated if FB
32. X ray neck AP view
•Round radio opaque
object ( Coin)
•In Esophagus
•Because the
esophagus is an AP
compressed tubular
structure
•A coin would
occupy this
position
•Can be confirmed
by lateral view
34. Foreign Body Ingestion
Common locations in esophagus
Cricopharyngeus
Aorta/left mainstem bronchus
Gastroesophageal junction
35.
36. Sialography
Radiologic examination of the salivary glands
The submandibular and parotid glands are
investigated by this method
The sublingual gland is usually not evaluated this
way
Difficulty in cannulation
37. Procedure
1. Obtain preliminary radiographs
• Any condition that is visibe w/o contrast
• Optimum technique obtained
2. 2-3 min before procedure give lemon
3. Contrast media (iohexol) injected into main duct
4. After procedure suck on lemon to clear contrast
5. 10 min after procedure take radiograph
44. bronchogram
Radiographic examination of the tracheobronchial
tree by radiopaque iodinated compound
(dianosil,iohexaol) in a low viscous suspension.
rarely performed today, having been superseded by
high resolution computed tomography HRCT
45.
46. BARIUM SWALLOW
procedure used to examine upper gastrointestinal
tract,which include the pharynx, esophagus, cardia of
stomach.
The contrast used is barium sulfate.
53. TECHNIQUE
PHARYNX
-One mouthful contrast bolus with high
density(250% w/v).
-Patient is asked to swallow once and stop
swallowing there after.
-This is to get optimum mucosal coating.
-frontal and lateral view x-ray taken.
54. ESOPHAGUS
Single contrast
-Multiple mouthful barium suspension given.
-prone swallow to assess esophageal contraction.
-useful in esophageal compression, displacement
or disordered motility.
57. Partially obstructing cervical
esophageal web.
Frontal view shows a
circumferential, radiolucent ring
(straight white arrows) in the proximal
cervical esophagus. Partial obstruction
is suggested by a jet phenomenon
(black arrows), with barium spurting
through the ring, and by mild
dilatation of the proximal cervical
esophagus .
58.
59. A Zenker's diverticulum is a pulsion hypopharyngeal
false diverticulum with only mucosa and submucosa
protruding through triangular posterior wall weak site
(Killian's dehiscence) between horizontal and oblique
components of cricopharyngeus muscle
61. CA ESOPHAGUSWith shouldering
The stenotic segment is long giving a “" *rat-tail” appearance
Barium swallow shows mild dilatation of the esophagus with irregular
stenotic lesion in the lower end of the esophagus “moth eaten appearance
63. 63
P-A Skull
Patient seated or standing
facing the Bucky.
Nose and forehead touching
the Bucky to get the
canthomeatal line
perpendicular to film.
64.
65. 65
P-A Skull Film
.There should be no rotation.
The petrous ridges will be
superimposed with the orbits.
To clear the ridges, the
Caldwell view can be taken.
66. 66
Chamberlain-Townes
Patient is seated facing the
tube.The chin is tucked into the
chest until the canthomeatal line
is perpendicular to film. A chair
the allows some reclining will
make this easier for the patient.
67. 67
Chamberlain-Townes Film
The entire skull and especially
the occipital region of the skull
must be on the film.
Structure seen include the
foramen magnum, petrous
ridges, IAC’s and TM Joints
No rotation of skull
68. 68
Skull Lateral
Patient seated of standing
facing the Bucky. Rotate the
body into an oblique position.
Turn skull so the affected side
is next to the Bucky.
The interpupillary line must be
perpendicular to film and tube.
Mid sagittal plane parallel to
the film.
69.
70. 70
Skull Lateral Film
Entire skull must be on the
film.
There should be no rotation of
the skull, orbits and mandible
ramus superimposed.
The facial bones are sinuses
will be dark (over exposed).
Usually both lateral views are
taken.
