EXPLORING MODULAR CONSTRUCTION WITH THE USE OF SHIPPING CONTAINERS FOR HOUSI...OLANREWAJU AKINOLA
The idea of using shipping containers as a building component and in architecture is by no means new in Lagos Metropolis. Most shipping container architecture conversions have however been for temporary accommodation needs, for example, storage, make-shift shops, emergency shelters and site offices. Nonetheless , this concept of using shipping containers as modular building components in architecture and green prefab home building designs is still foreign to building practitioners and residents of Lagos state.
Modular construction technology enables construction times and cost to be reduced by up to half that of traditional building techniques while remaining significantly more environmentally friendly. The use of shipping containers as modular building component in architectural design provides a recycled use for waste shipping containers and assists in reducing the embodied energy of buildings, which is lower in comparison to other building materials. Therefore as a by-product, the shipping container can be seen as a sustainable building component,
This study provides an insight on the feasibility of using ISO shipping containers to enhance the provision of housing in Lagos Metropolis, with a focus on the Apapa district. It also sets out to provide a view of the viability of this medium, together with the problems that may occur in implementing their use.

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.

Embracing GenAI - A Strategic ImperativePeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.
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.

3. Abstract
“The Edible Vegetative Roof: A Design for the Plant and Environmental Sciences Building at UC
Davis” is a project dedicated to creating a roof farm. It is meant to enhance the university, promote
sustainability, and raise awareness toward the endless abilities of an environment. It is designed as an
educational and economical resource on campus that takes a unique approach at fulfilling these ideals.
This project specifically looks into the benefits of creating an edible green roof, the various methods in
approaching such a scheme, and the opportunities and constraints that the site allows. The design draws from
these methods and selects elements that will help to fulfill the initial goals of the project.
My hopes in this project are to present to the public a unique way of viewing unused spaces, to
encourage urban farming and sustainable practices, and to expose the variety of ways of greening a roof. I hope
to show that through design, a multi-functioning environment can be created and remain sustainable.

unused roof areas (See Fig. 1.01). There are many benefits that an edible landscape can provide,
which include: utilizing space, controlling herbicide and pesticide
usage, reducing the demand for produce transportation, growing
unusual varieties, and saving money in the long run.
An edible landscape utilizes space by functioning in two ways.
The first way is to provide an aesthetic environment and to create an
atmosphere similar to those of conventional ornamental gardens.
Secondly, edible landscapes provide food in this same space. As a
result, two functions are being used in this one site.

11. One of the benefits is that a green roof reduces the urban heat
island effect. The urban heat island effect is when a metropolitan area
is significantly warmer than its surrounding rural areas due to urban
development and waste heat contributed by humans (See Fig. 1.02).
“The replacement of trees and vegetation with buildings and pavement
reduces the amount of shade and evaporation, resulting in less natural
cooling” (Environmental Protection Agency, 2002). A green roof
reduces this effect by creating more vegetation in place of these Fig. 1.02: Graph showing that an increase in built environment, leads to an increase

impervious surfaces, which promotes natural cooling.
Another benefit of a green roof is its ability to utilize space.
Rooftops are generally empty areas that are inaccessible to the public.
A green roof can then take those unused areas and give it a function. It
can provide an environment for people to enjoy, or provide cooling to

Typology
In this project, the main priorities of the garden include
growing an abundance of food and allowing experimentation with the
growing medium. Because of this, the type of vegetative roof chosen is
important. There are three possible ways to approach a vegetative roof,
and each method has its own strengths, weaknesses, and
specializations.
The first approach is the typical green roof. This is the most Fig. 2.01: Typical green roof layers (Left). Green roof on the Bronx County

quality crops (Garden Unit, 2008). Also, in this system, watering is
controlled and automatic, cycling the moisture so that it starts off
completely wet, then gradually dries out before it moistens the plant
again. This mimics the conditions of nature, giving the plants the
amount of water they need and results in less water usage and less
maintenance (Autopot, 2006).

in other systems). As a result, less energy is needed to operate this
system because it does not work unnecessarily (Autopot, 2006).
When it comes to the economical benefit of the edible
vegetative roof, the hydroponic system is the best bet. This is because
the hydroponic system is made to give the plants the exact amount of
water and nutrients that they need, resulting in more, good quality food

be pumped to all the plants in the Autopot system. As the water is
being pumped out, the feeder injects a calibrated proportion of part

a pressure meter and a nutrient monitor are added to the system,

adds the nutrient rich water into the tray up to a designated level; it
then closes and allows the water to drain completely. After the water
level reaches zero, the smart valve waits about 30 minutes before
opening and watering again (See Fig. 2.05). This hydrotray system is
ideal for larger plants, carefully watering and feeding each plant up to
20 feet tall (Autopot, 2006). This system is ideal for a large range of
plants, including tomatoes, melons, grapes, and cucumbers (See Fig.
2.06).
Fig. 2.05: A diagram of how the smart valve works.
Overall, this Autopot system is ideal for this project because it
grows an abundance of food, and consistently keeps the cycle of
growth going. This system is water and energy efficient, and allows
for quality fruits and vegetables to be sold to the public.

Site Accessibility
The edible vegetative roof is designed to be located on the Plant and Environmental Sciences Building (See Fig. 3.01). As mentioned earlier,
this is an ideal site for the project because of its proximity to its target market (See Fig. 3.02). In order for the green roof to be built and for the target
market to reach this roof top, the accessibility of the building must be taken into consideration.
Fig. 3.01: The front of the Plant and Environmental Sciences Building. Fig. 3.02: PES Building is adjacent to the Landscape Architecture Building and
the Memorial Union.
The Edible Vegetative Roof 17
20. Roof Access
The existing roof of the PES Building has two main tiers. The first tier is a slightly sloped roof that houses the roof and overflow drains. The
second tier holds the exhausts, house keeping pads, and mechanical equipment of the building. These areas should not be accessible by the public;
thus, the first tier is the better area for access (See Fig. 3.03).
Fig. 3.03: The red areas indicate the parts of the PES Building that are not accessible by the public.
The Edible Vegetative Roof 18
21. Stair Access
Currently, the PES Building has access to the roof from the inside via stairways and elevator. Since the building is occupied by many offices,
it is preferred to create access to the roof from the outside. This ensures that the employees will not be disturbed by the publicly accessible roof. Also,
the best external access to the roof will be areas with minimum window and utility blockage so that the offices with window views will not be
disturbed and utilities can be reachable from the ground (See Fig. 3.04).

Design
The edible vegetative roof is a roof used to grow edible crops. It is designed to creatively make use of initially unused spaces to promote
sustainability and urban greening. The main areas on the roof are used to allow students to experiment with water and soil, composting, and rainwater
harvesting, and to provide an economic benefit from the produce. The crops grown in this design will be sold at a student diner that will earn money
to further fund this project and for the university.

27. Safety
For the initial steps in creating this design, safety is the first concern in making the roof open to the public. Since the slopes on the accessible
areas of the roof are so slight, they do not have to be tampered with. The roof is lined with guard rails to allow the public to access it safely (See Fig.
5.04). The existing roof drains and back up drains are secured with wire caging, allowing water to still be able to flow into them. The caging will also
prevent people from tripping on the drains and will protect the drains from damage. After these safety modifications were addressed, the design
focused in on making the primary goals of the project plausible.

28. Water
To obtain water to use on the roof, two different approaches were used, both using rainwater harvesting.
In the first approach, a wooden, shallow planter area is created to catch the rain water and funnel it into the wooden rain barrels (See Fig.
5.05). The bottom of the planter is covered with a thin layer of rocks to help filter the rain water before it enters the barrels. The planter sits on
pedestals located along the support beams of the building to maintain the weight of the planter. Also, the wooden barrels are located along the edges
of the roof where there is strong beam support to hold up their weight when filled.
Fig. 5.05: Shallow planter used to collect and filter water for rainwater harvesting.
The Edible Vegetative Roof 26
29. Fig. 5.06: Red areas mark the location of rainwater harvesting.
In the second approach, rain is collected from ground level and is transferred up. In two different areas, a 423 gallon tank is located next to
one of the roof downspouts of the PES Building to collect rainwater from the roof. During dry seasons, this tank is filled with a water hose from
ground level when the water supply is low. An 1100 watt steel pump located inside of the 423 gallon tank can provide enough pressure to run the
water from the tank up to 147 feet in height. Because of this, the water will have enough pressure to reach the roof top, which is approximately 48
The Edible Vegetative Roof 27
30. feet from ground level. A hose will run from this tank, up to the roof top, where wooden barrels are located to harvest this water and provide the
water needed for the plants (See Fig. 5.07).

ground level (Middle), powered by a 1100 watt pump (Right) to bring
the water to the roof.

31. Stairs
Stairs are added to the outside of the building to ensure that the staff, faculty, and students are not disturbed by the public accessing the roof
from inside the PES Building. These stairs also encourage the public to visit the demonstration gardens and see edible landscaping and rainwater
harvesting in action. The stairs are located in an area with low window blockage to minimize the disturbance of those who gained window office
privileges (See Fig. 5.08). For those four windows that are in front of the stairs, a wall of art, vegetation, and light will cover the view of the stairs
and present a pleasant blend of beauty and nature in its place (See Fig. 5.09).

32. Experimentation Garden (Container Garden)
The first thing seen when entering the roof top is the experimentation garden. The experimentation garden is dedicated to be a demonstration
garden and to allow students to experiment with water, soil, composting, and rainwater harvesting. In the experimentation garden, there is a tool shed
to lock up and store equipment, wooden rain barrels to store water for the garden, composting bins to create compost from the student diner and
garden waste, shade cloth to prevent crop heat stress, and square foot gardens propped up on pedestals to allow uninterrupted water to flow into the
roof drains and to act as the planters used for growing the edible plants. Together, these elements create a crop producing and educational
environment reserved for the classes and students.

34. Production Garden (Hydroponic Garden)
Further away from the stairs and past the experimentation garden, the production garden is located (See Fig. 5.12). This limits the foot traffic
entering the area so that the produce is not disturbed. The production garden is the space dedicated to growing crops to feed the masses. The fruits
and vegetables from this garden are to be prepared and sold at a student diner located in the Memorial Union. In this production garden, there are two
types of hydroponic systems used to grow a high abundance of crops, a tool shed to store equipment, rain barrels to hold water for the garden, and
shade cloth to protect the crops from heat stress. This garden works to produce an abundance of fruit and vegetables year round to be sold in the
student diner and to generate funds to keep the project going.
