Encompassing nanoscale science, engineering, and technology, nanotechnology involves imaging, measuring, modeling, and manipulating matter at this length scale. A nanometer is one-billionth of a meter. A sheet of paper is about 100,000 nanometers thick; a single gold atom is about a third of a nanometer in diameter.

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.

The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.

How to Create Map Views in the Odoo 17 ERPCeline George
The map views are useful for providing a geographical representation of data. They allow users to visualize and analyze the data in a more intuitive manner.
We all have good and bad thoughts from time to time and situation to situation. We are bombarded daily with spiraling thoughts(both negative and positive) creating all-consuming feel , making us difficult to manage with associated suffering. Good thoughts are like our Mob Signal (Positive thought) amidst noise(negative thought) in the atmosphere. Negative thoughts like noise outweigh positive thoughts. These thoughts often create unwanted confusion, trouble, stress and frustration in our mind as well as chaos in our physical world. Negative thoughts are also known as “distorted thinking”.
4. WHAT
IS“NANOMATERIALS”?
Nanomaterials is a field that takes a materials
science-based approach to nanotechnology. It
studies materials with morphological features
on the nanoscale, and especially those that
have special properties stemming from their
nanoscale dimensions.
Nanoscale is usually defined as smaller
than a one tenth of a micrometer in at least
one dimension, though this term is
sometimes also used for materials smaller
than one micrometer.
5. WHAT IS TOXICOLOGY?
Toxicology is a branch of biology,
chemistry, and medicine concerned with
the study of the adverse effects of
chemicals on living organisms.
It is the study of symptoms, mechanisms,
treatments and detection of poisoning,
especially the poisoning of people.
It was found that various disciplines of
TOXICOLOGY were under study.
6. DISCIPLINES OF
TOXICOLOGY
Aquatic toxicology
Chemical toxicology
Ecotoxicology
Environmental toxicology
Forensic toxicology
Medical toxicology
7.
8. NANOTOXICOLOGY
Nanotoxicology is the study of the
toxicity of nanomaterials.
Because of quantum size effects and
large surface area to volume ratio,
nanomaterials have unique properties
compared with their larger counterparts.
9. Nanotoxicology is a branch of
bionanoscience which deals with the
study and application of toxicity of
nanomaterials.
Nanomaterials, even when made of inert
elements like gold, become highly active
at nanometer dimensions, these exhibit
toxicity.
10. Nanotoxicological studies are intended
to determine whether and to what extent
these properties may pose a threat to
the environment and to human beings.
For instance, Diesel nanoparticles have
been found to damage the
cardiovascular system in a mouse
model.
11. REASONS FOR TOXICITY OF
NANOPARTICLES
As it is well known fact that, when the
particle size of a material decreases, its
surface area to volume ratio increases,
leading to SPECIAL characteristic
properties as well different adverse
effects on ENVIRONMENT.
Due to the quantum size of these
nanoparticles these possess toxicity.
12. Like all nanomaterials, iron-based
nanoparticles ,like these can vary in their
toxicity, depending on their chemical
composition, coating, size, and shape.
To better assess the biological effects of
nanomaterials, researchers have
developed a rapid screening tool that can
evaluate large numbers of nanomaterials
and identify groups of materials that are
more likely to pose a risk.
13. David Rand, Robert Hurt and coworkers describe their
experiments, in which they exposed fruit fly larvae and adults to
various types of carbon nanomaterials. In case of the larvae,
some nanomaterial was accumulated in tissues, but had no
impact on the development or survival. If they exposed adult
flies to carbon nanomaterial, this exposure led to the flies’ death
within hours, previously impairing their mobility. SEM images of
the flies show severe damage to the flies legs and feet for
example. Referring to the authors, toxicity might be due to the
carbon nanomaterial adheres to the flies’ eyes and – more
problematic – to their breathing holes.
This result is also in line with the finding, that small aggregates
(e.g. carbon black; single-walled nanotubes) show higher toxicity
than than nanomaterials with larger aggregate sizes.
Furthermore, the scientist were able to show that the
contaminated flies are spreading the nanomaterials to ‘clean’
flies while grooming themselves.
17. As the developing concepts in
nanomaterials have their advantages, it
also has disadvantages.
So its necessary for all to concentrate
on the second side of the coin.
The researches all over the world begin
to put forward their efforts to create a
new generation of science with minimum
or without adverse effects.
