Water testing near Essex and Winooski sites test clean for PFOA

first_imgVermont Business Magazine Governor Peter Shumlin released today preliminary test results from private water supplies surrounding two former wire-coating facilities in Essex and Winooski.  All samples showed no presence of the potentially harmful chemicals PFOA and PFOS. The two sites are former locations of local wire coating and cable extrusion companies Belden Wire & Cable (Essex) and Super-Temp Wire and Cable (Winooski). An Environmental Protection Agency (EPA) contractor took five samples from residential wells near the former Belden Wire & Cable site in Essex, and five samples from wells owned by businesses near the former Super-Temp site in Winooski. All test results were non-detect for PFOA.The two former facilities represent two of eleven sites identified in a statewide plan announced by the Governor in March(link is external) to proactively test water in locations where there could be concern for elevated levels of PFOA. The wire coating industry, semi-conductor industry, and locations where fire-fighting foam was used repeatedly were identified as places that should be tested.The test results released today mean that water supplies sampled at four out of the eleven sites outlined in the statewide plan and tested by the EPA have now tested clean for PFOA. Testing of water supplies around Pittsford Fire Academy (Pittsford) and Phoenix Wire (South Hero) also returned results where PFOA was not detected.last_img read more

Will-writing and property firms bring ABS total to seven

first_imgTwo niche firms specialising in will-writing and property respectively have become the latest two organisations to be accepted as alternative business structures (ABSs). Parchment Group, based in Buckinghamshire, and three-partner firm Plainlaw, based in Oxfordshire, had their applications confirmed this week by the Solicitors Regulation Authority (SRA). The granted licences bring to seven the number of ABSs regulated by the SRA, with around 100 more at stage two of the application process. Parchment was a founder member of the Institute of Professional Willwriters and is the first non-solicitor firm to be granted the ABS licence by the SRA. Plainlaw, which specialises in property, housing and construction law, has an associated ‘corporate member’, Plainlaw.biz Ltd. Under the conditions of the licence, the sole purpose of Plainlaw.biz is to hold an interest in the licensed body and it cannot be held out as providing any type of legal service. Head of legal practice Philip Horn must be paid any profit share directly and not through Plainlaw.biz. Horn said the ABS licence ‘gives us additional flexibility in terms of structuring our business going forward. Our interest in the concept of ABS is driven more by the potential it offers us for the future, than by our current circumstances (where we not intending any immediate change). ‘Our focus will remain on providing a City of London-style real estate service but at provincial fee rates. We have developed a niche in providing an on-demand real estate support service to other leading law firms, many of whom will themselves be considering the benefits of converting to ABS status.’ Parchment, founded in 1989, has since branched out from will-writing to include lasting powers of attorney, probate and inheritance tax planning.last_img read more

Qorvo Demonstrates Ultra-Wideband Linearization for Massive MIMO Applications

first_imgLeading cellular operators are enhancing wireless spectrum efficiency and boosting network capacity by more than 500% by adopting technologies including Massive Multi-input Multi-output (MIMO), Active Antenna Systems (AAS) and LTE-Pro. Active Antenna Systems with 64 transceivers pose significant challenges to design power amplifiers with the small form factors, high efficiency and linearity needed for multi-carrier configurations. By combining Qorvo’s ultra-compact, advanced power amplifier (PA) modules with NanoSemi’s Digital Pre-distortion (DPD) intellectual property, operators are able to implement highly efficient, small form-factor Massive MIMO transceivers for next-generation base stations.They have also demonstrated linearization of the QPA2705 cascaded Doherty driver amplifier and QPD2730 dual-channel GaN Doherty PA final stage with -58 dBc for 60 MHz LTE signals, and -55 dBc for 100 MHz LTE signals.Qorvo is demonstrating their GaN power amplifiers for base station infrastructure at Booth 839 at the IEEE International Microwave Symposium (IMS), in San Francisco from May 24-26. Qorvo in conjunction with NanoSemi, have demonstrated ultra-wideband linearization results with their Gallium Nitride (GaN) power amplifiers for wireless infrastructure. NanoSemi is a leading developer of digital linearization and compensation algorithms.The QPA2705 from Qorvo is an integrated GaN driver and GaN Doherty power amplifier with 30 dB gain, P3dB of 44 dBm, PAE of 35% at 37 dBm average output power in a compact 6×10 mm surface mount package for next generation massive MIMO applications. Using this amplifier with NanoSemi’s proprietary digital compensation algorithms, they have achieved impressive results.last_img read more

Avnet Launches RF System-on-Module to Accelerate 5G Product Development

first_imgLeading global technology solutions provider, Avnet has announced the availability of the Avnet XRF16 system-on-module. This module is a 16-channel transceiver module capable of direct conversion of an RF waveform with a bandwidth of up to 5 GHz. The module takes advantage of the Xilinx Zynq UltraScale+ RFSoC Gen-2 device, the industry’s only single-chip, adaptable radio platform, making it ideal for RF applications such as 5G massive MIMO radio, phased array radar and multi-channel RF instrumentation, which demand small-footprint, low-power, and real-time processing.The XRF16 ADCs and DACs can operate at sampling rates of 2.22 GSPS and 6.554 GSPS, respectively, on 16 channels. High-speed digital connectivity is available for 100G Ethernet and PCIe, and baseband processing and network interface are handled by the Xilinx Zynq UltraScale+ RFSoC integrated quad Arm Cortex-A53 processing subsystem and programmable logic.Standard peripherals such as USB 3.0, Gigabit Ethernet, and serial UART are included. To support hardware prototyping and software development, Avnet has also launched a carrier card to provide a convenient interface to RF test equipment as well as 100G Ethernet and PCIe over cable (OCuLink).The XRF16 module enhances Avnet’s product offerings for developers working on applications that require next-generation 5G connectivity by accelerating valuable development and production time. As developers bring the newest applications to market, they are increasingly reliant on emerging 5G connectivity to enable their devices and deployments. With the XRF16, those developers can once again turn to Avnet’s end-to-end product development ecosystem for the tools they need to support their development process.With the XRF16 module and a comprehensive software suite, developers can begin prototype and application development immediately and move quickly to production with the same hardware, significantly reducing time to market. The XRF16 is an example of Avnet’s leadership in developing system-on-modules, which developers are increasingly turning to as they seek out small-footprint, low-power solutions that support real-time processing for applications such as 5G MIMO, radar, beamforming, and medical imaging.Technical specifications of the XRF16 Xilinx RFSoC System-on-Module 16-Channel/Gen-2/5 GHz:16x ADCs, 12-bit up to 2.220 GSPS16x DACs, 14-bit up to 6.554 GSPSQuad-core Arm Cortex-A53 processing subsystem1 GbE, PCIe Gen-2, SATA3.1, USB 2.0/3.0UltraScale+ programmable logicPhase coherent synchronous sampling across all converters and multiple boards16x 28 Gbps serial links for 10/40/100 GbE, PCIe Gen 3×16, eCPRI and AuroraThe Zynq UltraScale+ RFSoC Gen-2 family has been developed to extend the analog bandwidth of the 16T16R integrated multi-giga sample RF data converters for enhanced performance in demanding RF applications.
