  • Air quality one of many risk factors for IVF

    Pregnancy is a complex process in the best possible scenario - two people deciding to have a baby and conceiving naturally. Even then, many things can go wrong. There is truth in sayings such as “babies are miracles.” But what if a couple just doesn’t get pregnant? According to the CDC, infertility is a common concern in North America, affecting one out of every eight couples ...

  • Lufft handheld device for calibration purposes - XA1000 in use of BMB Laboratory in Zagreb - Case Study

    MTB inzenjering d.o.o. is a trade partner of our industrial measurement instruments in Zagreb, Croatia and our partner for ten years already. They are expanding their own laboratory (BMB laboratory) for calibration of relative humidity devices. For this, they recently needed a new, highly precise hand held device for reference measurements. They decided to rely on the XA1000 hand held device from ...

  • Compressed breathing air safety - how important is it?

    At first glance the physiological demands of the firefighter, the scuba diver and the hospital patient have little in common. One is trained to deal with fire and rescue, one swims underwater and one is concerned with either regaining or improving their health. Yet all three depend to some extent on a safe source of compressed breathing air, which is where our gas detection systems come in. ...

  • Laboratory test report - the effect of scale formation on heat transfer coils

    Background EVAPCO, Inc. recently introduced new Evaporative Condensers and Closed Circuit Coolers which utilize extended surface coils. For decades extended “fin” surfaces have been used on heat transfer coils, often referred to as “finned coils” primarily in an effort to increase dry capacity. However, in the past the fin material was limited to carbon steel tubes ...

  • Optimising laboratory environment for successful IVF

    The London Women’s Clinic in Cardiff (LWC Wales) is one of ten clinics within its group which collectively provide expert fertility treatment to families across England and Wales. When it comes to IVF and fertility treatment there is no ‘off-the-shelf’ or ‘one size fits all’ solution and, as such, the medical teams produce a bespoke fertility programme for each and ...

  • What is Indoor Air Quality?

    Indoor Air Quality (IAQ) refers to the degree of air purity inside buildings that constitute the usual environment in which people carry out activities (offices, homes, schools, shopping and leisure centres, etc.) Because of increasing urbanisation and our contemporary lifestyle, most people spend a large proportion of their time in these closed environments. The high level of atmospheric ...

  • Air Conditioning That`s Out of This World

    New materials enhance the cooling effects from outer space to reduce energy use in small- to medium-sized buildings Reducing air conditioning energy use by using new materials to enhance the cooling effects from outer space may not be such a far-out idea. In a simulation study using DOE's Energy Plus software and ...

  • How to Get Higher Acceptable Indoor Air Quality Anywhere

    The quality of the indoor air we breathe is a concern for everyone, especially those in urban environments where contaminant and particle levels are higher due to nearly constant exposure to things like automobile and truck exhausts, construction, and fumigation. Unfortunately for most people, when it comes to the quality of the air in the buildings where they spend most of their time, ...

  • Forward osmosis membrane fouling and cleaning for wastewater reuse

    Membrane fouling properties and different physical cleaning methods for forward osmosis (FO) and reverse osmosis (RO) laboratory-scale filtration systems were investigated. The membrane fouling, with respect to flux reduction, was lower in FO than in RO when testing an activated sludge effluent. Cross-flow velocity, air-scouring, osmotic backwashing and effect of a spacer were compared to ...

  • Explaining vehicle emissions – why do laboratory and road measurements differ?

    The road transport sector is a major contributor to Europe’s emissions of greenhouse gases and air pollution. For certain pollutants, vehicles can emit substantially higher emissions on the road than official emissions tested in laboratories. A report released today by the European Environment Agency (EEA) provides a non-technical guide that describes the reasons for these often significant ...

  • Air bubbles enhance membrane cleaning: a future perspective

    Abstract Air bubbles generated using a novel micro-bubble generator have displayed a dramatic enhancement in cleaning efficiency when used in conjunction with specially formulated cleaning chemicals. In order to establish the effect of this application on membrane performance, a series of experiments were conducted using both a flat sheet test rig and a small scale pilot plant. ...

  • Study: Stem Cells and Air Quality

    A recent study conducted by researchers at the State Key Laboratory of Environmental Chemistry and Ecotoxicology, Research Center for Eco-Environmental Sciences China, Chinese Academy of Sciences (CAS), and the University of California at San Diego (UCSD) were successful in using stem cells to determine the amount of BPA that caused physiological toxic effects.  The group of ...

  • Impact of withering process on sensory properties of black tea

    Withering is the first step in tea processing and has a significant impact on final product quality. During the tea green leaf withering and its preparation for the next stage of processing (curling), reduction in moisture content of the leaf is accompanied by occurrence of biochemical interactions that play an important role in product quality; its aroma in particular. Air flow rate and ...

  • California air resources board held a workshop on the low carbon fuel standard

    On April 3, 2015, the California Air Resources Board (CARB) held a Public Workshop to discuss updates to the California-Modified Greenhouse Gases, Regulated Emissions, and Energy Use in Transportation (CA-GREET) Model, version 2.0, under the Low Carbon Fuel Standard (LCFS). The update ...
