LBA Group, Inc. (LBA) announced that EMC Test Design, LLC has named its test equipment unit, LBA Technology, Inc., a distributor in the Americas for EMCTD Smart Fieldmeter® systems. Widely accepted for their high quality, EMCTD instruments are nevertheless among the lowest cost of competitive RF survey meters. LBA can now complement its traditional suite of RF safety services with a professional, cost effective broadband RF Safety survey meter selection. LBA’s EMCTD offerings will support FCC, OSHA, and international radio frequency compliance in the industrial, broadcast, and wireless communications markets. Broadband Smart Fieldmeters®, broadband RF probes, and accessories can be combined in many ways to suit industry-specific requirements. Broadband RF survey meters are used for laboratory testing of RF devices and maximum permissible exposure (MPE) surveys on broadcast, communications, medical, and industrial systems. Some industrial applications include surveys on RF welders, lasers, heat sealers and semiconductor production equipment. These meters are perfect for compliance tests on many types of RF producing equipment to demonstrate conformance with OSHA, FCC, ICNRP, Canada Safety Code 6, and other RF health standards. Recognizing that most users in its markets are not RF engineers, LBA has pre-engineered four versatile broadband Smart Fieldmeter® systems containing the correct instruments, probe(s) and accessories for OSHA/FCC compliance specialists to immediately apply to their needs in the broadcast, wireless communications and industrial sectors. The LBA function-engineered EMCTD broadband RF meter ensembles are ANGPE-3000 (general purpose analog), DIGPE-3000 (general purpose digital), DIGPEH-3000 (industrial and AM/SW broadcast) and the DIGMPE-8000 (shaped response for broadcast and wireless communications). “We’re pleased to now offer a solutions oriented ensemble of preselected RF Safety survey meters and accessories that are ready to go for our wireless and industrial customers,” LBA Test Equipment Specialist, Aaron Smith said. Beyond the pre-engineered systems, the full range of EMCTD test products is available from LBA Technology. These include digital and analog survey instruments, a full range of probes for both electrical and magnetic field measurements up to 40 GHz, utility accessories, and software options. Specifications for EMCTD Smart Fieldmeter® products are available HERE. “We are most excited about the addition of the EMCTD Smart Fieldmeter® line because this now makes LBA a complete one stop shop for all things related to RF Safety,” LBA COO, Mike Britner said. “Our NIER and other RF safety audits, RF safety awareness training, and selection of RF personal protective equipment have long been mainstays in the RF community,” Britner added.

The Amundsen Sea is characterized by a continental shelf, long-term sea ice, and many coastal polynyas with high biological productivity. Euphausia superba and Euphausia crystallorophias, which are dominant Antarctic krill, are major prey for most predators, such as fishes, birds, and marine mammals. An understanding of the feeding ecology of krill may provide the information for the structure and function of the Amundsen Sea ecosystem. Thus, we applied two biochemical approaches (fatty acids and stable isotopes) to determine the trophodynamics of adult krill in the Amundsen Sea. There were no significant differences in lipid contents between the two species, but the dominant storage lipids were different. Triacylglycerol (TAG) was dominant in E. superba, but wax esters (WE) were dominant in E. crystallorophias due to their different living strategies. Furthermore, the lipid content of E. crystallorophias displayed a spatial variation, being highest on the glacial edge. It was difficult to understand the feeding strategy and food source using only the fatty acid compositions of krill and in situ particulate organic matter. However, we found that specific FA ratios (18:1ω9/18:1ω7 and PUFA/SFA) and the nitrogen isotope ratio (δ15N) provide more insight into the feeding ecology of krill, such as feeding strategy and trophic position. These ratios suggest that E. crystallorophias consistently showed a higher degree of carnivorous feeding than E. superba in the Amundsen Sea during the austral summer. In conclusion, adult E. superba might more directly obtain their energy from in situ primary producers in the open sea, but, in the Amundsen Sea Polynya, adult E. crystallorophias seems to obtain their energy mainly through the microbial loop (microzooplankton). If so, E. crystallolophias would be a key player not only to transfer the energy from microbes to higher trophic levels but also to control the carbon and nitrogen cycle in the Amundsen Sea Polynya. © 2015 Elsevier Ltd.

Carbon cycling and productivity within Weno Island of Micronesia enclosed by the coral reef may be likely self-maintained and insignificantly affected by the open ocean. Therefore, it is important to understand the role of the mangrove known as providing the organic matter and habitats for many organisms in this enclosed area. In order to trace the nutritional source of fauna (mostly invertebrates) in the mangrove forest of Weno island, we analyzed the fatty acid (FA) and carbon and nitrogen stable isotopes of potential nutritional sources (mangrove leaf & pneumatophore, seagrass leaf & root, surface sediment, and particulate organic matter (POM) in water) and consumers (4 gastropods and anomura). The mangrove and seagrass contained the abundance of 18:2ω6, and 18:3ω3, whereas FAs associated with phytoplankton and bacteria were accounted for a high proportion in the surface sediment and POM. FA composition of consumers was found to be similar to those of the surface sediment, mangrove, and seagrass. These were also confirmed through the mixing model of stable isotope for contribution of nutritional sources to consumers. Overall results with the feeding types of investigated mangrove fauna indicate that investigated mangrove fauna obtained their nutrition from the various sources, i.e. the mangrove for Littorina cf. scabra, the microalgae for Strombus sp., and omnivorous Pagurus sp. and Terebralia cf. palustris. However, it is obvious that the nutrition of most species living in the mangrove ecosystem is highly dependent on the mangrove, either directly or indirectly. More detail food-web structure and function of the mangrove ecosystem would be established with the analysis of additional fauna and flora.
