Two toxic-unit models that estimate the toxicity of trace-metal mixtures to benthic communities were compared. The chronic criterion accumulation ratio (CCAR), a modification of biotic ligand model (BLM) outputs for use as a toxic-unit model, accounts for the modifying and competitive influences of major cations (Ca²(+), Mg²(+), Na(+), K(+), H(+)), anions (HCO₃⁻, CO²⁻₃ ,SO²⁻₄, Cl⁻, S²⁻) and dis...

In this letter, we propose a cooperative relaying system (CRS) combining orthogonal multiple access (OMA) and non-orthogonal (NOMA) for uplink transmission. the proposed system, cell-center user (CCU) amplifies forwards cell-edge (CEU) signal to base station (BS), meanwhile transmitting its own signals by NOMA. This win-win operation drives CCU CEU work together, is particularly useful when hol...

The PCIM CCU was set up in June 2006 from the Department of Internal Medicine at the University Hospital of Guadalajara, reaching out to primary care (PC), with the aim of achieving collaboration and coordination between the two levels of care and avoiding the sense of imposition that can be felt in primary care with regards all that comes from the hospital. To this end, several meetings were h...

The incidence of Ureaplasma urealyticum in endourethral swabs was compared with that in first voided urine specimens from 171 male patients. The organism was isolated from the urethras of 72 (42%) and from the urine of 66 (39%). The interval since last voiding urine did not significantly influence the incidence of infection or ureaplasma counts in either type of specimen. Urethritis was strongl...

This paper introduces a calculus for concurrent update (CCU) that is used to specify distributed objects. The calculus permits updates to be effected immediately at each site − no central server, locking, token passing, rollback, or other form of serialization is enforced. Notice of each update at each site is transmitted to every other site, where a corresponding update is effected. Unless spe...

Background In future Denmark the majority of acute admissions passes through Emergency and Acute Admission Departments (EAAD). For patients with Acute Coronary Syndrome (ACS) considerable improvements have been achieved through the Cardiac Care Units (CCU). Among patients with acute chest pain only a minority have an ACS. This raises the question if it is possible to separate patients with a hi...

Heavy industries such as cement, iron and steel, oil refining, petrochemicals are responsible for about 22% of global carbon dioxide (CO2) emissions. There exist several pathways CO2 mitigation. Capturing, storage, utilization (CCS CCU) provide an operational solution significant emission High purity streams the most interesting points CCS CCU. Pure suitable compression, transport, storage.

OBJECTIVE To Evaluate the clinical outcome of patients with acute coronary syndrome (ACS) in the Coronary Care Unit (CCU) over three decades in Dunedin, New Zealand. DESIGN Registry study. SETTING AND PATIENTS all consecutive patients (n = 3,013) with ACS admitted to the CCU from 1979 to 1981 (n = 966) and from 1989 to 1991 (n = 1470) were included prospectively. Data on ACS patients manage...

OBJECTIVES To assess whether having received grey packets containing treatment for gonorrhoea and chlamydia was associated with condom use among female sex workers (FSWs) in 5 districts of southern India covered by the Avahan programme where both periodic presumptive treatment (PPT) and syndromic management were used to control these sexually transmitted infections (STIs) among FSWs.
