Is steel still the best material for building? | HowStuffWorks - 0 views

  •  
    structural steel beams set in concrete allowed them to frame tall buildings that were more fire resistant and more structurally sound than cast iron. Since that time, steel (an alloy made by combining iron and carbon) has not only become the best building material for commercial construction but closely tied to economic health. In fact, many experts look to the steel industry as an indicator of how well the economy is doing [source: Pamuk]. Steel has a long history in the construction industry, but is it still the best material for building?" While no one alternative has become a standard to replace steel, materials like engineered timber and metal composites are becoming more common in new construction projects. "Timber companies tout wood as a durable, renewable resource, and engineered timber is gaining some traction as an alternative to steel. For example, the new arts and media building at Nelson Marlborough Institute of Technology in New Zealand used engineered wood in place of typical steel and concrete construction, and the company that worked on that building says that it's taking on more and more contracts that would have gone to steel construction companies [source: Nelson Mail]."

    DRIVER-INFRASTRUCTURE-FUNDING-POLITICS 5-year update to 50-year Texas Water Plan QUICK FACTS: **Texas' state water plans are based on future conditions in the event of a recurrence of the worst recorded drought in Texas' history-known as the "drought of record"-a time when, generally, water supplies are lowest and water demands are highest. **Texas' population is anticipated to increase 73 percent between 2020 and 2070, from 29.7 million to 51.5 million, with approximately half of this growth occurring in Regions C and H. Water demands are projected to increase less significantly, by approximately 9 percent between 2020 and 2070, from 17.7 million to 19.2 million acre-feet per year. **Texas' existing water supplies-those that can already be relied on in the event of drought-are projected to decline by approximately 18 percent between 2020 and 2070, from 16.8 million to 13.8 million acre-feet per year primarily due to reservoir sedimentation and depletion of aquifers. **Water user groups face a potential water shortage of 3.1 million acre-feet per year in 2020 and 6.9 million acrefeet per year in 2070 in drought of record conditions. **Approximately 5,800 water management strategies recommended in this plan would provide 1.7 million acrefeet per year in additional water supplies to water user groups in 2020 and 7.7 million acre-feet per year in 2070. **Conservation strategies represent approximately 29 percent, or 2.2 million acre-feet per year, of all recommended water management strategy volumes in 2070 and were recommended for more than half of the water user groups in the plan. **The estimated capital cost to design, construct, and implement the more than 2,400 recommended water management strategy projects by 2070 is $80 billion. If strategies are not implemented, approximately one-quarter of Texas' population in 2070 would have less than half the municipal water supplies they will require during a drought of record. **If Texas does not implement the sta

Sustainability | Special Issue : Materials and Corrosion - 0 views

  •  
    "Corrosion has a huge economic, environmental and sustainability impact on virtually all facets of constructional materials, from highways, bridges, and buildings to oil and gas, chemical processing, desalination, nuclear, power facilities, water, and wastewater systems. In addition to causing severe environmental damage and threats to public safety, corrosion disrupts operations and requires extensive repair and replacement of failed assets. The annual cost of corrosion worldwide was estimated to exceed $U.S.2.5 trillion in 2016, which translates to 3 to 4% of the Gross Domestic Product (GDP) of industrialized countries according to NACE IMPACT study report. (...) To reduce the huge cost and the environmental impact of corrosion and enhance the sustainability of materials used for construction, available corrosion control practices such as proper material design and selection, the use of corrosion inhibitors, coatings, cathodic protection etc., are recommended and could lead to savings of between 15 and 35% of the cost of corrosion. This translates to between US$375 and $875 billion annually"

Field Sensor for Measuring Total Trihalomethanes (TTHM) Concentrations in Drinking Wate... - 0 views

  •  
    DRIVER-TREATMENT-TTHM-POLITICAL CLASS-ACTION LAWSUIT Rapid detection of the total trihalomethanes (TTHM) in treated drinking water is essential for compliance with the Environmental Protection Agency's (EPA) Stage 2 Disinfectants and Disinfection Byproducts (DBP) Rule, which limits the maximum contaminant level of TTHM in drinking water. The current detection method for TTHM determination involves sending samples to EPA certified laboratories for gas chromatography analysis; a method that is both expensive and time consuming. In the Phase I, Agave BioSystems demonstrated proof of concept for a sensitive colorimetric TTHM detection system based on a modified Fujiwara reaction, which can be integrated into a portable field sensor. This assay system utilizes a modified Fujiwara reaction to yield a detectable color product that correlates directly to the TTHM levels of the water sample. In this Phase II, Agave BioSystems proposes to construct a compact and portable rapid response TTHM water monitoring system for field use. BENEFIT: TTHM is linked to increased rates of bladder and colorectal cancers, and several studies link TTHM to heart, liver, and central nervous system damage. The EPA estimates that lowering TTHM levels in as few as 1,200 small drinking water systems could prevent up to 20 cases of bladder cancer per year, resulting in economic benefits of up to $110 million per year. Another documented health risk is the increased rate of miscarriage and congenital birth defects in areas with high TTHM levels. A Virginia based class action lawsuit seeking more than $1 billion in damages, claims that peak TTHM occurrences in one water distribution system may have led to multiple miscarriages. A cost effective and easy to use field portable sensor, such as the one proposed by Agave BioSystems, would enable drinking water delivery systems of any size to effectively monitor the levels of TTHM in their water supply on a more frequent basis, and allow proactively treating

Federal Water Pollution Control Act (Clean Water Act) - 0 views

  •  
    DRIVER-TREATMENT-POLITICS-POLLUTION The original 1948 statute (Ch. 758; P.L. 845), the Water Pollution Control Act, authorized the Surgeon General of the Public Health Service, in cooperation with other Federal, state and local entities, to prepare comprehensive programs for eliminating or reducing the pollution of interstate waters and tributaries and improving the sanitary condition of surface and underground waters. During the development of such plans, due regard was to be given to improvements necessary to conserve waters for public water supplies, propagation of fish and aquatic life, recreational purposes, and agricultural and industrial uses. The original statute also authorized the Federal Works Administrator to assist states, municipalities, and interstate agencies in constructing treatment plants to prevent discharges of inadequately treated sewage and other wastes into interstate waters or tributaries.

A once-quiet battle to replace the space station suddenly is red hot | Ars Technica - 0 views

  •  
    A Houston-based company called Axiom Space has been most public about its intentions, talking for a few years now about developing the world's "first commercial space station." But this week, two other options emerged for NASA: Nanoracks and Lockheed Martin announced their intent to build a space station called "Starlab," and another team led by Blue Origin and Sierra Space revealed plans to construct an "Orbital Reef." If multiple options become available for space travel the price will be forced down, allowing for more people to travel and experience The Overview Effect. This could result in more influential people aligning with addressing climate change. Microgravity also allows some sections of science to mature much faster, resulting in more breakthrough technologies coming to market faster.
