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.

The bamboo stalk is a strong, lightweight, renewable material that has a high tensile strength. It is widely acknowledged that bamboo culms have contributed significantly to architecture because of their environmentally friendly nature. Five different types of three-year-old bamboo were studied (Dendrocalamus asper, Dendrocalamus sericeus, Dendrocalamus membranaceus, Thyrsostachysoliveri, and Phyllostachysmakinoi) for their culm features and qualities. The findings demonstrate that in addition to culm length, each bamboo species has unique culm properties. The outer culm diameter and culm wall thickness in particular have an impact on the ultimate load. These findings support the idea that a larger culm with a thicker wall might support greater weight. T. Oliveri earned the lowest ultimate load, while D. Asper received the highest. However, when calculating the test results for stress (load per cross-section area), P. Makinoi showed excellent mechanical properties, while D. asper showed the worst mechanical properties. This research promotes bamboo’s appropriate use for building applications and as a more sustainable material for architecture.

Immunizing Image Classifiers Against Localized Adversary Attacksgerogepatton
This paper addresses the vulnerability of deep learning models, particularly convolutional neural networks
(CNN)s, to adversarial attacks and presents a proactive training technique designed to counter them. We
introduce a novel volumization algorithm, which transforms 2D images into 3D volumetric representations.
When combined with 3D convolution and deep curriculum learning optimization (CLO), itsignificantly improves
the immunity of models against localized universal attacks by up to 40%. We evaluate our proposed approach
using contemporary CNN architectures and the modified Canadian Institute for Advanced Research (CIFAR-10
and CIFAR-100) and ImageNet Large Scale Visual Recognition Challenge (ILSVRC12) datasets, showcasing
accuracy improvements over previous techniques. The results indicate that the combination of the volumetric
input and curriculum learning holds significant promise for mitigating adversarial attacks without necessitating
adversary training.

NUMERICAL SIMULATIONS OF HEAT AND MASS TRANSFER IN CONDENSING HEAT EXCHANGERS...ssuser7dcef0
Power plants release a large amount of water vapor into the
atmosphere through the stack. The flue gas can be a potential
source for obtaining much needed cooling water for a power
plant. If a power plant could recover and reuse a portion of this
moisture, it could reduce its total cooling water intake
requirement. One of the most practical way to recover water
from flue gas is to use a condensing heat exchanger. The power
plant could also recover latent heat due to condensation as well
as sensible heat due to lowering the flue gas exit temperature.
Additionally, harmful acids released from the stack can be
reduced in a condensing heat exchanger by acid condensation. reduced in a condensing heat exchanger by acid condensation.
Condensation of vapors in flue gas is a complicated
phenomenon since heat and mass transfer of water vapor and
various acids simultaneously occur in the presence of noncondensable
gases such as nitrogen and oxygen. Design of a
condenser depends on the knowledge and understanding of the
heat and mass transfer processes. A computer program for
numerical simulations of water (H2O) and sulfuric acid (H2SO4)
condensation in a flue gas condensing heat exchanger was
developed using MATLAB. Governing equations based on
mass and energy balances for the system were derived to
predict variables such as flue gas exit temperature, cooling
water outlet temperature, mole fraction and condensation rates
of water and sulfuric acid vapors. The equations were solved
using an iterative solution technique with calculations of heat
and mass transfer coefficients and physical properties.

2. Enlist interesting facts about Bamboo tree.
• Size of bamboo depends on the species. Largest species of bamboo can
reach 1300 feet in height.
• Bamboo can grow either as woody, tall plant or as shorter, herbaceous
plant.
• Individual stems of bamboo are called culms. They arise from the
underground rhizome and emerge from the ground fully developed.
• Flowers of bamboo are rarely seen. Some species of bamboo develop
flowers after 65 or 120 years. Interesting fact about flowering is that all
plants of one bamboo species develop flowers at the same time, no
matter where they are located in the world.
• Besides from rhizome, bamboo can develop from the seeds arranged in
clusters at the end of the branches.
• Bamboo is the fastest growing plant on the planet. It can grow 3 feet in
height in 24 hours under appropriate climate conditions. Unlike other
woody plants, bamboo reaches maturity after only 3 to 5 years.
• Bamboo releases 30% more oxygen into the atmosphere and absorbs
more carbon dioxide compared to other plants. Because of these
features, bamboo greatly decreases amount of greenhouse gases in the
atmosphere and cleans the air.

6. ADVANTAGES OF BAMBOO
The various advantages of bamboo are mentioned below.
• Light, strong and versatile.
• Light, strong, versatile.
• Environment friendly.
• Accessible to the poor.
• Self renewing resource
• Fast growing.
• Highly productive.
DISADVANTAGES OF BAMBOO
• The major disadvantages of bamboo are as follows:
• Requires preservation
• Shaped by nature
• Durability- bamboo is subjected to attack by fungi, insects;
for this reason, untreated bamboo structures are viewed as
temporary with an expected life of not more than 5 years.
• Jointing- although many jointing techniques exist, their
structural efficiency is low.
• Lack of design guidance and codes.
• Prone to catch fire very fast by the friction among the culms
during wind, and is seen to cause forest fires.
What are advantages and disadvantages of the Bamboo construction?
7. How Bamboo is treated for durability? Elaborate.
• Traditional or non-chemical methods:
These are ancient methods widely used for centuries by villagers and artisans in countries where bamboo grows, and
often the skills are passed on from generation to generation. The most commonly methods used are smoking, white-
washing, storage in water.
• Smoking:
Smoking is carried out in chambers. Heat and toxic agents produced by smoke destroy the starch in bamboo making it
immune to insect attack and also blackens the culms. There are, in Japan, bamboo houses older than 100 years. The
smoke from the kitchen (fireplace without chimney) spreads throughout the house and thus preserves the bamboo
structure from any attack.
• Baking over open fire:
Baking over fire after applying oil on the surface of green round bamboos. This causes rapid drying of the outer shell and
induces partial charring and decomposition of starch and other sugars. This method is very useful for simultaneous
straightening of bamboos in round form.
• White washing:
Bamboo culms are painted with slaked lime, thereby prolonging their lifespan by delaying and reducing the absorption of
moisture while being a repellent against insects.
• Soaking in water:
Freshly cut bamboo is stored either in water ponds or in running water for 3-4 weeks to leach out starch. This process
protects the bamboo against insects. When stored in water basins, water must be changed frequently to avoid fouling.
Although traditionally treated bamboo shows increased resistance to insects and fungi attack compare to the freshly cut
culms, these methods do not however provide complete satisfaction in the long term.
8. • Chemical treatment methods
Chemical preservatives are used to protect bamboo products from degradation. These are well
methods providing good protection even in adverse conditions.
• Tanalised method - chromated copper arsenate (CCA)
As for wood, bamboo products are often tanalised, impregnatedunder pressure or by boiling with highly
toxic substances such as chromated copper arsenate (CCA)to protect against rot. TheCCA has been very
effective but very toxic and carcinogenic. Other products are used as "ammoniacal copper arsenate" or
Ammoniac facilitating penetration in bamboo or wood makes this product effective against fungi, bacteria
and insects. Ammoniac and copper components are highly and eco-toxic non-degradable.
• Treatment with Boric acid / Borax
The preservative used is a mixture of boric acid and borax which result in the formation of disodium
octaborate, which is easily soluble in water. Boron salts are effective against borers, termites and fungi
(except soft rot fungi), and is widely recognized to be environmentally acceptable and safe for the
9. various failure modes of Bamboo structures.
Slenderness failure:
• Slenderness as a failure criterion means also that the stem of trees have to be
well tapered .
• This means that the stem diameter increases downwards in
relation to the increasing bending moment . In a bamboo the thickness
of the culm does not increase.
• There seems to be another kind of adaptation by
increasing the wall thickness downwards to adjust the increasing bending
moment.
• Figure shows the alteration of the wall thickness and diameter along a
bamboo culm, scaled on the values at the bottom of the culm. Resulting from this
the degree of hollowness decreases and therefore the load capacity increases
Hollow failure:
• The culms of some bamboo species have Height/DBH ratio of 80 and higher.
Bamboo culms are hollow tubes divided by nodes into sections called internodes.
Those nodes support the culm to prevent failure due to local buckling.
• The length of the internodes along the culm increases from the base of the culm
towards somewhere below the middle, and then decreases till top of the culm.
13. What are various parts of Bamboo? (explain with sketch) Which part is strongest?
STEM
• The stem is the part of the bamboo plant that grows above the ground, it is usually
straight and cylinder-formed (to some extent oval). These bamboo stems
have nodes (diaphragms) between two internodes, that strengthen the stem. It is
strongest part.
• The length, number and form of nodes and internodes depend on the bamboo
species. Every node has two closely positioned rings, the lower one is called sheath
ring, which is a scar formed after the sheath leaf falls off.
• Bamboo internodes are usually hollow inside and form bamboo cavities. A good
example of a near solid bamboo species is Guadua amplexifolia.
STEM BASE
• The lower part of a bamboo stem is called stem base, it extends into the
soil and connects to the rhizome and root system. A stem base consists of
numerous short sections with significant diameter, adventitious roots grow
densely on these sections.
STEM PETIOLE:
• The stem petiole is the lowest part of the bamboo stem, and consists of
tens of short sections. The diameter of these sections decrease with the
depth of the petiole. A stem petiole is generally solid, with degenerated
leaves, without buds.
