The essential requirements that hearing protectors need to fulfil as personal protective equipment are evaluated in Argentina through a series of IRAM (Instituto Argentino de Normalización y Certificación) standards. In particular, IRAM 4060-3 (equivalent to ISO 48693:2007) standard specifies a simplified method for the measurement of insertion loss (IL) of earmuff type protectors. This method ...
We present the results of a CO(1-0) emission survey with the IRAM 30m of 30 galaxies at moderate redshift (z ∼ 0.2-0.6) to explore galaxy evolution and in particular the star formation efficiency, in the redshift range filling the gap between local and very high-z objects. Our detection rate is about 50%. One of the bright objects was mapped at high resolution with the IRAM interferometer, and ...
We report the detection of 6 active galactic nuclei, and also the marginal detection of the galactic center radio source SGRA*, in 215GHz VLBI observations between the IRAM 30m telescope on Pico Veleta and one 15m antenna of the IRAM Plateau de Bure interferometer (∼ 0.3mas fringe spacing). In this (second) 1.4mm VLBI-experiment we find source dependent ratios between the total and correlated f...
RpoS, the master sigma factor during stationary phase and under a variety of stress conditions, is regulated at multiple levels, including regulated degradation. Degradation is dependent upon ClpXP and the RssB adaptor protein. H-NS, a nucleoid-associated protein, affects the regulated degradation of RpoS; in the absence of H-NS, RpoS is stable. The mechanisms involved in this regulation were n...
The goal of Intelligent RAM (IRAM) is to design a cost-effective computer by designing a processor in a memory fabrication process, instead of in a conventional logic fabrication process, and include memory on-chip. To design a processor in a DRAM process one must learn about the business and culture of the DRAMs, which is quite different from microprocessors. We describe some of those differen...
The IRAM CORE large program combines data from NOEMA and the 30m telescope to study a diverse set of physical chemical processes during formation high-mass stars. Here, we present selected compilation exciting results obtained survey.
Aims. As a part of the CALYPSO Large Program, we aim to constrain properties protostellar jets and outflows by searching for corresponding emission in sample 21 Class 0 protostars covering broad range internal luminosities ( L int from 0.035 ? 47 ). Methods. We analyzed high angular (~0.??5–1.??0) resolution IRAM Plateau de Bure Interferometer (PdBI) observations three typical outflow jet trace...
