Bamboo is one of the oldest construction materials. It has been used all over the world as the building materials in the form of walls, roofs, foundation, reinforcements and decorations.
At the same time, it acts as the good earthquake resistance material.
Bamboo (Bambuseae) is a tribe of flowering perennial evergreen plants in the grass family Poaceae, subfamily Bambusoideae, tribe Bambuseae; although, the forestry services and departments of many countries where bamboo is utilized as a building material consider bamboo to be a forestry product, and it is specifically harvested as a tree exclusively for the wood it produces, which in many ways is a wood superior in strength and resilience to other natural, fibrous building materials.In fact it is often referred to as a tree by cultures who harvest it as wood. Giant bamboos are the largest members of the grass family. In bamboos, the internodal regions of the stem are hollow and the vascular bundles in the cross section are scattered throughout the stem instead of in a cylindrical arrangement. The dicotyledonous woody xylem is also absent. The absence of secondary growth wood causes the stems of monocots, even of palms and large bamboos, to be columnar rather than tapering.Bamboos are some of the fastest-growing plants in the world,due to a unique rhizome-dependent system. Certain species of bamboo can grow 35 inches within a 24-hour period, at a rate of 3 cm/h (a growth of approximately 1 millimeter (or 0.02 inches) every 2 minutes). Bamboos are of notable economic and cultural significance in South Asia, Southeast Asia and East Asia, being used for building materials, as a food source, and as a versatile raw product. Bamboo has a higher compressive strength than wood, brick or concrete and a tensile strength that rivals steel.
The word bamboo comes from the Kannada term bambu, which was introduced to English through Malay.

Bamboo, like true wood, is a natural composite material with a high strength-to-weight ratio useful for structures.
In its natural form, bamboo as a construction material is traditionally associated with the cultures of South Asia, East Asia and the South Pacific, to some extent in Central and South America, and by extension in the aesthetic of Tiki culture. In China and India, bamboo was used to hold up simple suspension bridges, either by making cables of split bamboo or twisting whole culms of sufficiently pliable bamboo together. One such bridge in the area of Qian-Xian is referenced in writings dating back to 960 AD and may have stood since as far back as the third century BC, due largely to continuous maintenance.
Bamboo has also long been used as scaffolding; the practice has been banned in China for buildings over six stories, but is still in continuous use for skyscrapers in Hong Kong.In the Philippines, the nipa hut is a fairly typical example of the most basic sort of housing where bamboo is used; the walls are split and woven bamboo, and bamboo slats and poles may be used as its support.
Bamboo can be utilized as a building material. Bamboo has a long and well-established tradition as a building material throughout the world’s tropical and sub-tropical regions. It is widely used for many forms of construction, in particular for housing in rural areas, it grows approximately 7.5 to 40cm a day. It is light, strong and versatile.

Bamboo, low cost, fast growing, and broad distribution of growth, is expected to contribute significantly to earthquake-resistant construction and seismic retrofit technology in the developing countries
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.
The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

24. Limitations and drawbacks
Few considerations currently limit the use of bamboo as a universally
applicable construction material
ø Jointing techniques - Although many traditional joint types exist, their
structural efficiency is low. Considerable research has been directed at
the development of more effective methods.
ø Flammability - Bamboo structures are not fire-resistant, and the cost of
treatment, where available, is relatively high.
ø Splitting – Low strength along fibres causes it to split or crack.
ø Lack of design guidance and codification - The engineering design of
bamboo structures has not yet been fully addressed. There is little or no
data containing specifications of bamboo.
25. CONCLUSIONS
ø Based on the research results of bamboo obtained in universities and
other institutes around the world the first norms for bamboo were
created determining the physical and mechanical properties of bamboo.
ø These norms have been evaluated by International Code Council and will
be included in the ISO norms in near future.
ø The results of the investigations show that bamboo can substitute steel
satisfactorily
ø There is a need to introduce formal education on the use of bamboo as a
structural material in design and technical schools.
