Poly-Optic® 14-Series Casting Resins are two-part,
polyurethane systems formulated specifically for applications where
optical clarity is required. Castings are clear like water; however,
PolyColor dyes can be added to obtain clear, colored castings. PolyOptic systems, with low viscosities and long pot-lives, provide for easy
mixing, excellent detail penetration, and easy degassing, through
vacuum or pressure casting techniques, for bubble-free castings.
Poly 74-Series Polyurethane Rubbers consist of two
parts (A and B), which, after mixing, cure at room temperature to
flexible, high-strength, mold rubbers. Poly 74-Series Rubbers make
durable, easy-releasing molds for casting plasters and waxes without
release agents. When Poly 74-Series molds are properly prepared, they
are also excellent for casting concrete and various resins, such as epoxy,
polyester, polyurethane and acrylic

Responsive. Adaptive. Mobile first. Cross-channel. We all want a future that’s flexible, fluid, and unfixed from the desktop, right?
Great. Then it’s time to get to the core of the matter: the content.
Fixed firmly to inflexible pages, today’s content is too often stuck in meaningless blobs—blobs that break under the weight of responsive designs, mobile sites, and cross-channel distribution.
Which elements are most important? What’s primary and what’s corollary? What’s related or interdependent? What stays, what goes, and what gets truncated on small screens?
When we can answer these questions—and structure our content accordingly—we’ll replace those messy blobs with content that bends, shifting and reshaping to fit varied displays and devices.

Cosmetic shop management system project report.pdfKamal Acharya
Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers. It should help the employees to quickly identify the list of cosmetic product that have reached the minimum quantity and also keep a track of expired date for each cosmetic product. It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.
CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!
Work done in cooperation with James Malloy and David Moelling from Tetra Engineering.

Courier management system project report.pdfKamal Acharya
It is now-a-days very important for the people to send or receive articles like imported furniture, electronic items, gifts, business goods and the like. People depend vastly on different transport systems which mostly use the manual way of receiving and delivering the articles. There is no way to track the articles till they are received and there is no way to let the customer know what happened in transit, once he booked some articles. In such a situation, we need a system which completely computerizes the cargo activities including time to time tracking of the articles sent. This need is fulfilled by Courier Management System software which is online software for the cargo management people that enables them to receive the goods from a source and send them to a required destination and track their status from time to time.

2. RIW CementFLEX
TYPICAL USES
Cementflex is ideally suited for waterproofing and
protecting concrete and masonry structures which
exhibit cracking, and where further movement is
expected. Typical applications include preventing
water ingress into basements, cellars and other below
ground structures. The product can also be used for
sealing water tanks, waterproofing of exposed or
buried roofs, and as a crack isolation membrane on
concrete floors or screeds.
The product when mixed exhibits a good degree of
thixotropy to enable ease of application by brush
or spray techniques to give an even finish with no
sagging even in vertical situations. It hydrates to form
a durable, highly alkaline, permanently elastomeric
coating which not only protects the concrete, or other
substrates, from water penetration and carbon dioxide
diffusion, but also accommodates movement in
cracks. The elastomeric coating maintains its flexibility
under permanent immersion and when exposed
externally.
DURABILITY
Subject to normal conditions of use, Cementflex will
provide an effective barrier to the transmission of
liquid water for the life of the structure.

All surface laitance should be removed, preferably
using wet grit, power washing techniques or other
equivalent approved methods.
Damaged areas should be repaired as necessary,
using Cementfill HB if appropriate.
MIXING
Shake bottle thoroughly, and pour into the tub
supplied. Slowly add the powder, and mix for a
minimum of 5 minutes until homogeneous.
The modules must be mechanically mixed using a slow
speed drill and paddle, specially designed to entrap as
little air as possible.
Bottles of liquid and bags of powder are not to be split.
APPLICATION
The above preparation / remedial works should be left
until ‘stable’ before application of the Cementflex; ie:-
a minimum of one (1) hour, generally 2 to 3 hours.
Cementjoint should also be used when necessary, to
reinforce joints subject to movement ; see separate
data sheet.
The mixed slurry can be applied by brush, trowel or
spray to a pre-soaked surface. Take care to ensure
that air is not entrapped into the surface.
Apply as a single 2mm layer to horizontal surfaces,
spreading with a skid leveller or notched trowel, and
immediately use a spiked roller to release entrapped
air.
For other surfaces, the product should be applied in
two 1mm coats. The second coat should be applied
when the first is stable, but not fully set ie: after
waiting approximately 4 to 6 hours, dependent upon
temperature.
RIW Cementfill WP – a rapid setting waterproof
mortar plugging and sealing compound for arresting
water ingress.
RIW Cementjoint – a flexible waterproof composite
tape, for embedding in Cementseal, to reinforce joints

CONSTRUCTION
IMPORTANT NOTES
1. Existing substrates and structural elements
should be assessed for suitability to withstand any
increase in applied loads from water pressure.
2. Apply only to clean, sound substrates which
should be saturated but surface-dry and free of
back water pressure.
3. Care should be taken when curing in hot, sunny or
windy conditions.
4. Cementflex is not a decorative finish and may
temporarily discolour until uniformly weathered.
GENERAL
All construction should conform to the Building
Regulations, Codes of Practices and British Standards
in current use at the time the building is being
constructed. In particular it is recommended that
reference is made to BS 8102: 2009.
PREPARATION
All surfaces: The areas to be treated must be free from
all loose and unsound material ie: dust, oil, grease,
corrosion by-products and organic growth. Roughen
smooth surfaces.
The prepared substrate should be thoroughly soaked
with clean water, until uniformly saturated, without
standing water removed.
Internal corners should be eased with Cementfill HB
as a continuous ‘fillet’ (minimum 25 x 25mm), prior to
application of Cementflex.
Any sharp edges, ledges, holes, etc. are to be
smoothed or filled as required, using Cementfill FC or
Cementfill HB to suit.
Cementseal Primer should be first used on all
horizontal and porous surfaces, as necessary; see
separate data sheet.
Existing Surfaces: All existing finishes must be
completely removed back to the structure.
The entire substrate should be pressure washed. This
method is also the best way to saturate the surfaces,
and remove soil, dust and any other loose debris from
the existing wall.
Mortar joints should be checked to ensure they provide
a sound a substrate, onto which the main cement-
based coating can be applied.
Defective mortar joints should be raked out, and
repointed using Cementfill HB.
Damaged brickwork etc, should be repaired as
necessary; the area may be dubbed out if required, or
deep repairs, made using Cementfill HB. If necessary,
a smoothing coat of Cementfill FC may be applied.
Masonry surfaces: Should be sound with joints flush
pointed or ‘bagged out’, with Cementfill FC before the
Cementflex is applied.
