HETEROKARYOSIS AND PARASEXUALITY IN FUNGI- AD. MYCOLOGY -PLANT PATHOLOGY
The term heterokaryons (hetero=dissimilar, karyons=nuclei) has been defined as the coexistence of genetically-different nuclei in a single cell.
The phenomenon was discovered by Hansen and Smith (1932) in Botrytis cinerea.
FORMATION OF HATEROKARYOSIS
1. Mutation,
2. Anastomosis
3. Inclusion of dissimilar nuclei
FUNGAL PERASEXUALITY
One such novel alternative to sexual reproduction was discovered in fungi (Aspergillus nidulans) by Pontecorvo and Roper in 1958. This they named as the parasexual cycle.
STEPS OF PARASEXUAL CYCLE:
Establishment of Heterokaryosis,
Formation of heterozygous diploids,
Occasional mitotic crossing-over, during multiplication of the diploid nuclei, and
Haplodization through aneuploidy.

Yes some of the jobs are in decliened state due to online marketing .pdfaparetail
Â
Yes some of the jobs are in decliened state due to online marketing and internet facilities.Some
of these are:
1. Bank Workers
Weâre doing more and more banking online these days, and even though some Australian banks
are advertising that you can find âreal peopleâ in their branches to assist you, the customer
service element of banking is sharply in decline.
Services that have been traditionally performed by tellers are now done electronically. Automatic
teller machines are being used more frequently and tellers are only needed for complex
transactions. A bank teller needs to have very good attention to detail and they often have to
learn about a particular banking product that their company offers. They also generally need to
be good with people and customer service.
2. Filing and Registry Workers
Weâre not using paper files as much anymore; with some school leavers not having that many
opportunities to even use a pen these days. Environmental factors also come into play, with lots
of businesses choosing to limit the amount of paper files that they keep or print.
Itâs becoming less and less important for most businesses to employ someone just to file
documents as technology has increased; most workers are able to perform this function
themselves. Keeping copies of important documents in hard copy is still a necessary occurrence
in many cases, but more often than not, having digital copies of documents is more time and
space efficient. Filing workers need to have great organisation skills and be good with systems
and dealing with different types of people and management levels.
3. Manufacturers
In Australia, we are seeing more and more manufacturing moving overseas. Itâs well understood
that Australia is a high wage country, and has been since the 1820s. After Federation, high wages
were cemented in place by reformers and trade unions; Australian governments were among the
first to grant age pensions and other welfare benefits as well.
The downside is that Australian manufacturing has become uncompetitive against nations whose
manufacturers âcarried lighter burdensâ. Chesty Bonds, King Gee and Hard Yakka have joined
âa conga line of Aussie brands exiting the countryâ leaving many individuals jobless.
4. Data Entry/Keyboard Operators
Over the last two decades, the amount of data generated has grown, but these days there is less
need for a person to translate, transfer or manipulate this data, as a lot of this is now done
automatically. Another reason for the drop in employment is the fact that where companies still
use data entry operators, they may outsource this function to overseas where wages are lower.
For those people who are thinking about a job in this field, or for those who are currently
employed in this line of work, contemplate expanding your skill-set to encompass other valuable
office skills.
5. Postal Worker / Mail Sorter
The number of people who are employed in positions where they sort and distribute mail has
sharply declined.

The value of a IEEE-754 number is computed assign 2exponent m.pdfaparetail
Â
The value of a IEEE-754 number is computed as:
sign * 2exponent * mantissa
The sign is stored in bit 32. The exponent can be computed from bits 24-31 by subtracting 127.
The mantissa (also known as significand or fraction) is stored in bits 1-23. An invisible leading
bit (i.e. it is not actually stored) with value 1.0 is placed in front, then bit 23 has a value of 1/2,
bit 22 has value 1/4 etc. As a result, the mantissa has a value between 1.0 and 2. If the exponent
reaches -127 (binary 00000000), the leading 1 is no longer used to enable gradual underflow.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
Â
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 wasnât 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.
