The presentation emphasizes that PP 84 allows for innovation while providing a framework for quality control and assurance. It also discusses efforts to help agencies and industry transition to performance-based specifications through resources on specification development and quality control testing.
Fly ash availability is decreasing due to plant closures across 25 states. Over 11% of coal fired generating capacity has been reduced, with over 40% reductions in the Midwest, Mid-Atlantic, and Southeast regions. This has led to over 7 million tons less fly ash being produced annually. The document was presented by Megan Dangel from Central Plains Cement Company at a concrete paving workshop to discuss issues regarding decreasing fly ash supply.

ABC in Nebraska: Belden to Laurel BridgeJill Reeves
This document summarizes the replacement of the Belden-Laurel Bridge in Nebraska using accelerated bridge construction (ABC) techniques. The old 3-span steel girder bridge from 1938 was deteriorating and in need of replacement. The new single-span bridge features precast concrete girders, deck panels, abutment caps, wing walls, and approach slabs that were assembled on site to replace the bridge over a weekend, minimizing road closure time. The precast elements were connected using self-consolidating concrete, ultra-high performance concrete, and high-early strength concrete to accelerate construction.

Iowa DOT - Council Bluffs Border City AgreementsJill Reeves
1. For loads coming into Sioux City, Iowa under the exempt commercial zone, operating authority is not needed as long as the load is delivered within 6 miles of Sioux City.
2. For intrastate loads originating and ending in Iowa, a motor carrier needs an Iowa Motor Carrier Permit which must be carried in each vehicle.
3. Sioux City ordinance allows vehicles legal in weight and length in Nebraska or South Dakota to operate in Sioux City without an Iowa permit if traveling to or from those states.
This document outlines Nebraska's testing of aggregates for alkali-silica reaction (ASR) from 2008 to present. It discusses:
1) Correlating ASTM C1293 testing from 2008-2016 with FHWA TP-65 to classify aggregate reactivity.
2) Introducing AASHTO T380 mini prism testing in 2016 and correlating results to ASTM C1293.
3) Changing the blended/interground cement specification in 2016 to require ASTM C1567 or AASHTO T380 testing depending on expansion results. Testing aims to ensure aggregates and cements do not cause excessive expansion due to ASR.

Sri Guru Hargobind Ji - Bandi Chor Guru.pdfBalvir Singh
Sri Guru Hargobind Ji (19 June 1595 - 3 March 1644) is revered as the Sixth Nanak.
• On 25 May 1606 Guru Arjan nominated his son Sri Hargobind Ji as his successor. Shortly
afterwards, Guru Arjan was arrested, tortured and killed by order of the Mogul Emperor
Jahangir.
• Guru Hargobind's succession ceremony took place on 24 June 1606. He was barely
eleven years old when he became 6th Guru.
• As ordered by Guru Arjan Dev Ji, he put on two swords, one indicated his spiritual
authority (PIRI) and the other, his temporal authority (MIRI). He thus for the first time
initiated military tradition in the Sikh faith to resist religious persecution, protect
people’s freedom and independence to practice religion by choice. He transformed
Sikhs to be Saints and Soldier.
• He had a long tenure as Guru, lasting 37 years, 9 months and 3 days
Properties of Fluids, Fluid Statics, Pressure MeasurementIndrajeet sahu
Properties of Fluids: Density, viscosity, surface tension, compressibility, and specific gravity define fluid behavior.
Fluid Statics: Studies pressure, hydrostatic pressure, buoyancy, and fluid forces on surfaces.
Pressure at a Point: In a static fluid, the pressure at any point is the same in all directions. This is known as Pascal's principle. The pressure increases with depth due to the weight of the fluid above.
Hydrostatic Pressure: The pressure exerted by a fluid at rest due to the force of gravity. It can be calculated using the formula P=ρghP=ρgh, where PP is the pressure, ρρ is the fluid density, gg is the acceleration due to gravity, and hh is the height of the fluid column above the point in question.
Buoyancy: The upward force exerted by a fluid on a submerged or partially submerged object. This force is equal to the weight of the fluid displaced by the object, as described by Archimedes' principle. Buoyancy explains why objects float or sink in fluids.
Fluid Pressure on Surfaces: The analysis of pressure forces on surfaces submerged in fluids. This includes calculating the total force and the center of pressure, which is the point where the resultant pressure force acts.
Pressure Measurement: Manometers, barometers, pressure gauges, and differential pressure transducers measure fluid pressure.
Prediction of Electrical Energy Efficiency Using Information on Consumer's Ac...PriyankaKilaniya
Energy efficiency has been important since the latter part of the last century. The main object of this survey is to determine the energy efficiency knowledge among consumers. Two separate districts in Bangladesh are selected to conduct the survey on households and showrooms about the energy and seller also. The survey uses the data to find some regression equations from which it is easy to predict energy efficiency knowledge. The data is analyzed and calculated based on five important criteria. The initial target was to find some factors that help predict a person's energy efficiency knowledge. From the survey, it is found that the energy efficiency awareness among the people of our country is very low. Relationships between household energy use behaviors are estimated using a unique dataset of about 40 households and 20 showrooms in Bangladesh's Chapainawabganj and Bagerhat districts. Knowledge of energy consumption and energy efficiency technology options is found to be associated with household use of energy conservation practices. Household characteristics also influence household energy use behavior. Younger household cohorts are more likely to adopt energy-efficient technologies and energy conservation practices and place primary importance on energy saving for environmental reasons. Education also influences attitudes toward energy conservation in Bangladesh. Low-education households indicate they primarily save electricity for the environment while high-education households indicate they are motivated by environmental concerns.

A high-Speed Communication System is based on the Design of a Bi-NoC Router, ...DharmaBanothu
The Network on Chip (NoC) has emerged as an effective
solution for intercommunication infrastructure within System on
Chip (SoC) designs, overcoming the limitations of traditional
methods that face significant bottlenecks. However, the complexity
of NoC design presents numerous challenges related to
performance metrics such as scalability, latency, power
consumption, and signal integrity. This project addresses the
issues within the router's memory unit and proposes an enhanced
memory structure. To achieve efficient data transfer, FIFO buffers
are implemented in distributed RAM and virtual channels for
FPGA-based NoC. The project introduces advanced FIFO-based
memory units within the NoC router, assessing their performance
in a Bi-directional NoC (Bi-NoC) configuration. The primary
objective is to reduce the router's workload while enhancing the
FIFO internal structure. To further improve data transfer speed,
a Bi-NoC with a self-configurable intercommunication channel is
suggested. Simulation and synthesis results demonstrate
guaranteed throughput, predictable latency, and equitable
network access, showing significant improvement over previous
designs

12. Alternative Exposure Control
Methods
• OSHA is assuming an overexposure for all
activities that involve dry cutting with no
dust capture system.
• Companies have to have data collected
from an accredited testing company that
shows the actual amount of respirable
silica the employee(s) are exposed to.
• Respiratory protection will then be
selected based on this number
13. Action Level and PEL
• Employees who are above the Permissible
Exposure Level (50 μg/m3) must be
protected.
• Employees who are or may reasonably
expected to be above the Action Level (25
μg/m3) must have their exposure assessed
• Employees at or above these levels must
have a Written exposure control plan
14. Action Level
• If initial monitoring shows exposures below
the action level, testing may be
discontinued
• If monitoring indicates that exposures are
above the AL but at or below the PEL, the
employer will repeat the monitoring within
6 months of the most recent monitoring.
• Employer may discontinue monitoring if
two consecutive measurements are found
to be below the AL.
15. Permissible Exposure Level
• If levels are above the PEL, the employer
must repeat monitoring within three
months of the most recent monitoring.
16. Notification of Testing
• OSHA requires that employees are
notified within 5 days of the employer’s
receipt of testing results.
• The notification must be in writing or
posted in an area that is accessible to all
affected employees.
• If the levels are above the PEL, the
employer must describe the corrective
action(s) taken to reduce the affected
employee(s) exposure below the PEL
17. Respiratory Protection
• Employees cannot just wear disposable
respirators when exposed to silica
• The TWA (time weighted average) must
be determined and an appropriate
respirator selected based on the Assigned
Protection Factor.
• Disposable Respirators—APF 10
• Half Mask Respirators—APF 10
• Full Face Respirators—APF 50
18. Respiratory Protection
• Employees who are required to wear a
respirator by the standard (even
disposable respirators) for more than 30
days a year are required to be put into a
medical surveillance program
19. Goal of Silica Safety Program
• Eliminate employee overexposure
• Control health hazards associated with
overexposure
20. Crystalline Silica PELs:
“Bottom Line” Message
• Whatever the worksite: The more
crystalline silica there is in the dust, the
less of the dust may be breathed
21. Ways to Reduce Exposure
• Substitute materials that have no
crystalline silica
• Locate employees as far as possible from
dust-generation source
• Isolate employees OR the source
– Control rooms
– Enclosures
– Barriers
29. Management of Subs
• Subs who generate silica
– Masonry Contractors
– Finishers
– Concrete Cutters
– Caulkers
• Do not allow dry cutting, open cabs, leaf
blowers
• Separate these activities from other
workers
30. Training
• Employers are to designate a person who
is in charge of the Silica program
• Employers must ensure that employees
can “demonstrate knowledge and
understanding” of the Silica program
• OSHA states that the employer must even
ensure that the health care providers they
use for anything related to Silca have the
OSHA standards
31. Summary
• Exposure to Silica can be dangerous
• Dry methods of abrasive cutting, drilling or
blasting are pretty much against OSHA
• A program/plan must be implemented by
each company that has exposure to Silica
• Training is required for all workers who are
exposed.
