Denim is a sturdy cotton warp-faced textile in which the weft passes under two or more warp threads. This twill weaving produces a diagonal ribbing that distinguishes it from cotton duck.
Denim is available in a range of colors, but the most common denim is indigo denim in which the warp thread is dyed while the weft thread is left white. As a result of the warp-faced twill weaving, one side of the textile is dominated by the blue warp threads and the other side is dominated by the white weft threads. Jeans fabricated from this cloth are thus predominantly white on the inside.

Preparation of Firefighting Hood for Cooling For Phase Change MaterialsIJERA Editor
There are two types of Phase Change Materials (PCMs) which have been developed and adopted in textiles: heat (energy released) and cool (energy absorbed). This paper discusses current PCM applications and explores future applications in firefighting gear. Phase change materials are considered latent heat storage units because as they change phase from solid to liquid, liquid to gas and vice versa, energy in the form of heat is absorbed or released. The goal of PCM textiles is to create reusable energy to maintain body temperature, as well as to optimize the performance of protective wear such as hoods. When the wearer’s body temperature increases or decreases, the PCMs applied to the fabric will change state helping to regulate the wearer’s body temperature by providing warmth or cooling. Maintaining a stable body temperature can improve working conditions and comfort.

Experiments were conducted drying aonla flakes at air velocities of 0.48m/s, temperatures ranging from 40-75°C, and relative humidity of 35%. Moisture content was measured periodically to calculate moisture ratios. Various drying models (Newton, Page, Modified Page) were evaluated based on their ability to predict experimental moisture values using statistical measures like RMSE, chi-square, and efficiency. The Modified Page model with an exponent of 1 provided the best fit to experimental data with minimum RMSE and chi-square values and maximum efficiency. Correlations were developed between drying coefficient (k) and shape
Investigation of Thermal Insulation on Ice CoolersIOSR Journals
This document investigates different materials for thermal insulation in ice coolers. It tests coconut fibre, polystyrene, and polyurethane at various densities using the Lee's Disk method to determine thermal conductivity. The study finds that polyurethane with a density of 95kg/m3 has the lowest thermal conductivity of 0.0195 W/mK. Numerical analysis confirms that polyurethane of this density and thickness of 64mm maintains the lowest inside temperature for an ice cooler. The experimental data and numerical analysis show that polyurethane of 95kg/m3 density and 64mm thickness provides the best thermal insulation to minimize heat transfer and increase ice melting time in coolers.

How to Make a Field Mandatory in Odoo 17Celine George
In Odoo, making a field required can be done through both Python code and XML views. When you set the required attribute to True in Python code, it makes the field required across all views where it's used. Conversely, when you set the required attribute in XML views, it makes the field required only in the context of that particular view.

2. THERMAL MANIKIN
Thermal Manikin is a human model to measure clothing insulation and to evaluate the
relationship between thermal environment and thermal comfort. Thermal manikins are
complex, delicate and expensive instruments.
Thermal manikins can react as a human being and some thermal manikins can also
simulate human perspiration. The day is not so far when the Walking Position will be
introduced on the thermal manikins.
3. REASON FOR USING THERMAL MANIKINS
• The thermal manikin usually predicts values of some indicators of human heat strain like
core & skin temperatures, sweat loss, heat storage and so on at a specific time intervals
during a simulated exposure. These values are used to indicate the safe or practicable
working situations.
As example:
• In the HEAT: The duration of safe work or rest periods and measures to prevent
dehydration
• In the COLD: The need for whole-body insulation
4. IMPORTANCE OF THERMAL MANIKIN
The Thermal Manikin offers the following significant performances:
Relevant simulation of human body heat exchange
Whole body & local heat fluxes
Measurement of three-dimensional heat exchange
Integration of dry heat losses in a realistic manner
Objective method for measurement of clothing thermal insulation
Quick, accurate & repeatable
Cost effective instrument for comparative measurements & product development
Provides values for prediction models
5. ESSENTIAL PROPERTIES FOR THERMAL MANIKINS
Thermal manikins need to have the certain properties in order to simulate the
human body accurately.
Correct Body Shape and Size
Perfect Control of Heat Emission
Proper Control of Heat Distribution across the Skin Surface
Correct Emission rate of the skin
Accurate Control of the Distribution of Perspiration across the skin surface.
6. DESIGN OF THERMAL MANIKIN
Advanced Thermal Manikins are consisted of three basic elements with
optional additional features
a. Temperature Sensors: The exterior skin of the manikin can be made of fiberglass,
polyester, carbon fiber, or other heat conducting materials which works as a
temperature sensors in each measurement zone.
b. Heating Elements: There are Coiled Wire under the skin which is controlled by Software
and heated through Electric Power.
c. Human Simulation: Some supplemental devices with additional mass may be fitted that
initiate general human actions like breathing, walking & sweating.
7. SPECIFICATIONS OF THERMAL MANIKIN
The following qualities are must to have in a Good Thermal Manikin:
• Strong Body: Must be stable & reliable
• Joints: Must be able to move in all directions and sit, walk & stand naturally. Clothes should not stuck in the joints.
• Perfect Human Body Shape
• Uniform Wiring: To ensure accurate heating only 2.2mm distance should keep between two wires.
• Intelligent Circuit: To calculate the entire surface temperature accurately.
• Four Control Modes: To automatic Calibration & internal data logging
• No heating
• Heating to a fixed set point
• Heating with fixed heat loss
• Following a Human comfort equation
8. INPUTS REQUIRED FOR THERMAL MANIKINS
The manikins respond to a HEAT or COLD stress depending on an interaction of
variables which describe 4 factors.
• Individual Expose: Size, Gender, Physical Fitness, State of Heat Acclimation
• Thermal Environment: Air Temperature, Air Speed, Water Vapor Content & Radiant
Temperature
• Clothing Worn: Resistance to Sensible & Evaporative heat loss, Weight, Air permeability
• Nature of Work: Duration, Metabolic heat produced, Mechanical work achieved.

24. RESEARCH ON ADAM MANIKIN
HERE ARE THE FOUR RESEARCH / TESTS ARE DESCRIBED..
1.0 NAVY CLOTHING AND TEXTILE RESEARCH FACILITY
2.0 NAVY FIRE SCENARIOS
3.0 NAVY ENSEMBLE
4.0 TEST FACILITY
25. NAVY CLOTHING AND TEXTILE RESEARCH FACILITY
• The organization focuses their efforts on research and development of textiles and materials
• Those were worn by our nation’s military for a variety of scenarios from moisture protection
• Sailors’ dry-suits to materials protecting soldiers from biomedical hazards.
• This facility’s objectives also include the protection of military (and civilian) fire fighters from thermal
injuries in fire conditions.
• Currently the Navy is restricted to testing fire fighter turnout gear on bench-scale
• testing apparatus in their facility, leaving all full scale testing to the DuPont Thermo-Man manikin
26. NAVY FIRE SCENARIOS:
• LeBlanc analyzed possible fire scenarios in the engine room, berthing or supply areas, and the deck
using computer models and hand calculations
• After investigation of these scenarios he determined that the majority of fires on board naval vessels
would be so severe that no protective clothing would survive (LeBlanc, 62).
• He focused his research on fires that were controllable; where fire fighters might find themselves
working.
• His final conclusions determined that the clothing test methods in 1998 did not accurately reflect fire
scenarios.
• That might be experienced by fire fighters, and therefore testing methods should be revised
27. TEST FACILITY:
This facility was built at Alden Research Labs in Holden, Massachusetts, and was designed/constructed by
WPI students .The design
was focused on producing a test facility that can accurately portray naval shipboard fires.
28. REPRODUCING REAL FIRE CONDITIONS
These tests recorded baseline functions of the apparatus. It was determined that the original design and
configuration (as of 2002) was capable of creating fires in excess of 2 MW (Fay, 79). Data was gathered on 1
MW fires to determine what fluxes aninstrumented manikin would be exposed to in the facility at this burn
rate.
29. NAVY ENSEMBLE
The Navy ensemble consisted of the United States Navy’s First Attack fire suit, a Navy helmet and gloves, as
well as a Scott SCBA and regular rubber boots. The suit is constructed of a Kevlar/PBI Outer Shell, Nomex
Moisture Barrier, and a Kevlar Batt Thermal Liner.
The ensemble can be seen as tested in Figure 4-36, without the navy helmet and gloves, and rubber boots.
32. ADAM
• ADAM means ‘Advanced Automotive Manikin ‘.
• A forerunner of such a new generation of manikins –ADAM was developed for the
American National Renewable Energy Laboratory for comfort testing.
• It remains the world's most advanced thermal comfort manikin and represents a true
leap in technology for thermal manikin research.
• Subdivided into 120 individual porous metal sweating zones, ADAM was designed to
evaluate the highly non-uniform and transient environments in vehicles and aircraft.
• The manikin mimics human responses such as sweating and breathing with incredible
accuracy and responds rapidly to environmental changes.
Fig: ADAM
33. APPLICATION (ADAM)
• ADAM was designed to evaluate the highly non-uniform and transient environments in
vehicles and aircraft.
• ADAM also used for thermal comfort research.
• Used in Ventilated Seat Application.
• Used in Liquid Cooling Garment Application.
Fig: Liquid Cooling Garment
Fig: Ventilated Seat
35. APPLICATION
• The Sweating Agile Thermal Manikin (SAM) was developed to test
complete clothing systems Under Normal and Extreme Conditions.
• It’s main purpose to test moisture transport, thermal insulation, and
their interaction influence both the comfort and protective
properties of clothing systems.
• It simulates the human body in terms of heat production, sweat
production, and movement as closely as possible. Thus inherent
costs of human tests and the possible risk to life.
36. CONTINUE…
• It offers the facility to test products from the clothing industry as
well as to develop prototypes into finished products more
efficiently with lower expenditure.
• Thus helps in the field of protective clothing (fire-fighter clothing
etc.), where in most cases a conflict exists between the demands for
protection and for the comfort of the wearer. By balancing these
two factors accidents caused by heat stress can be avoided.
