PME’s miniDOT® logger Aids Researchers in Dissolved Oxygen and Temperature Monitoring
The origin of the miniDOT® Logger came from a quick sketch on a napkin in a bar by the founder of PME, Mike Head in 2009. From there the R&D process began and the miniDOT’s first calibration was made in 2011. For more than a decade, miniDOTs have been chosen by researchers, universities, and government agencies worldwide to learn more about the water around them and provide the ...

High-Resolution Temporal Monitoring of an Arid, Urban Lake - Case Study
Overview Tempe Town Lake is an artificial lake located near the urban core of Tempe, AZ, derived from the damming of the Salt River. It was constructed in 1999 primarily for the use of recreation such as fishing and boating. This lake is Arizona’s second most visited tourist attraction that generated a cumulative economic impact of over $1.5 billion dollars since its creation, so it is ...

Promoting the growth of high quality goods and the phasing out of shoddy products
Conventional economic growth actually measures throughput, not accumulated wealth, as conventional growth measurements do not take account of the short life of goods and the loss to the economy when they are discarded. This article argues that society should be seeking growth in the quality of goods and services. This change from quantity to quality is necessary because Western industrialised ...

Effect of non-point source runoff and urban sewage on Yaque del Norte River in Dominican Republic
A Yaque del Norte, Dominican Republic watershed survey monitored dissolved oxygen, eutrophication from point and non-point sources, and high conductivity resulting from agricultural runoff. The upper mainly forested watershed had good water quality except for untreated sewage from the city of Jarabacoa. The mid-watershed had a deforested landscape, mixed agriculture and the city of Santiago ...

What is Nominal Length of LED Tubes?
Nominal sizes serve as “general descriptions” for lighting manufacturers when identifying a range or category of products. The nominal size of a unit is typically not the same as the exact measurement of the product. Instead, the nominal size can be referred to as a standardized dimension for a set of or several units in the same series. For example, a standard 3.54-inch floppy ...

Biochemical and morphological responses in chironomus riparius (Diptera, Chironomidae) larvae exposed to lead‐spiked sediment
The aim of the present study was to assess the potential use of biochemical markers and mentum deformities as indicators of long‐term exposure to lead (Pb) in Chironomus riparius larvae. To do this, we measured three biochemical markers (i.e malondialdehyde level, metallothionein concentration and energy reserve content) as well as larval growth and mentum deformities after 16 days exposure to ...

Simplify DO Monitoring with Flexible, Low-Maintenance Sensors
Simplify DO Monitoring with Flexible, Low-Maintenance Sensors There’s no bigger priority in wastewater treatment than monitoring dissolved oxygen–and making sure measurements are accurate. Inaccurate DO measurements are disastrous for process and budget. Pump too little oxygen and the organisms converting ammonia can die, putting the whole process on hold until you can get bacteria ...

Optimal location of flow intercepting facilities to improve security in urban areas
The problem of the optimal location of control facilities in an urban area for improving security in case of large events or critical situations is presented. The paper focuses on the prevention of threats by the control and/or the interdiction of people and vehicle flows entering an area (restricted zone). In general, limited available resources do not allow monitoring all the access points of ...

Franklin, NC - Case Study
Upgrade of 200 HP Orbital Oxidation System Wayne Price, Plant Operator In early 2006, the city of Franklin purchased a single S&N Airoflo 2000 Series 15 HP Floating Brush Rotor with EZ Access platforms and Allen Bradley SMC Soft Starts. Over the next 18 months, the city purchased eight more units, for a total of 135 HP. In 2008, DO monitors were added to three of the units. According ...

ppb Dissolved oxygen measurement
Dissolved oxygen (D.O.) measurement is one indicator of water quality because oxygen is a common element contributing to corrosion reactions. This corrosion reaction provides the need for low level D.O. control since dissolved oxygen is responsible for costly replacement of piping and equipment by corrosive attack on metah. what is Dissolved Oxygen? Dissolved axygan (D.O.f is the amount of ...

Impact of carbon to nitrogen ratio on nitrogen removal at a low oxygen concentration in a sequencing batch biofilm reactor
A sequencing batch biofilm reactor (SBBR) filled with polyurethane (PU) was operated in low dissolved oxygen (DO) (0.1–0.9 mg/L) at three different carbon to nitrogen ratios (C/N ratios) (C/N = 1.8:1, 5.0:1 and 10.5:1) with focus on reactor performance and microbial community composition of nitrifying and denitrifying bacteria. Meanwhile, the ammonium, nitrite, nitrate, pH and ...

Planning For Fenceline Monitoring
The development of a general framework for fence-line monitoring can go a long way toward getting a plan quickly implemented, with less stress and potentially large cost-savings. Automation can greatly reduce operational costs of the fence-line monitoring as well as reducing data loss due to equipment problems. No facilty expects to do fence-line monitoring, therefore they seldom plan for it, but ...

Automated Quality Control: More Precise, More Productive
With the constant pressure put on the market, both from the customers and competitors, the need to increase speed, efficiency and productivity is pushing many transport and automotive companies to switch to automated quality control. By doing so, they are moving away from traditional control methods such as conventional coordinate measuring machines (CMMs) and checking fixtures. But why? And is ...

Using the Package Profiler to Greatly Improve Equivalent Drop Height Measurement
Abstract: In the past, several methods have been used to estimate an "equivalent drop height". Of course, no package experiences a pure free-fall drop height every time -- quite the contrary. Hence, the need to typify the many impacts, bumps and shocks that occur to a package in the field. Understanding this can help you to develop more accurate and realistic packaging tests in your lab, avoid ...

Biotechnology in the global economy
Agricultural biotechnology is the subject of extensive public debates in many countries. This article summarises the results of the International Conference on Biotechnology in the Global Economy held in September 1999 at Harvard University. The article shows that many of the debates are a result of a governance challenge involving the need to bring social institutions in line with advances in ...
