Abstract:
Abstract Background Serum sodium concentration could be spuriously reduced by excess glucose or lipid; thus, hyponatremia should be reassessed before reporting in order to exclude the possibility of pseudohyponatremia. Methods In this study, we used the calculation of corrected serum sodium concentration in hyperglycemic or lipemic samples and evaluated its effect on the reduction in frequency of reports on pseudohyponatremia. We retrospectively analyzed 1-year data from the laboratory information system. Results From August 2017 to July 2018, hyponatremia was initially noted in 30,465 results

Hypernatraemia is much less common than hyponatraemia, and its prevalence is higher in certain populations, including children, the elderly, and critically ill patients. A common feature is that patients affected have been unable to drink water to correct the disorder. Hyponatraemia and hypernatraemia are both primarily disorders of water balance. Hypernatraemia is caused by a relative deficit of total body water in comparison to total body sodium. Both disorders are often associated with disturbances in the hormone governing water balance, arginine vasopressin (antidiuretic hormone). Hypernat

Abstract:
Abstract The success of a boiler water treatment program is dependent upon the correct dosage added to the feedwater. An all-polymer internal treatment product containing a proprietary fluorescent tracer has been developed and field tested for the purposes of monitoring treatment concentration, determining concentration cycles, and improving dosage control through automation. Tracer fluorescence measured in the boiler feedwater directly correlated to treatment concentration. By measuring fluorescence in the blowdown, the average boiler concentration cycles was determined using a tracer, and th

Abstract:
Abstract Amorphous aluminous silica (AAS) scale samples from the Wairakei and Ohaaki power stations, New Zealand, have been characterized chemically and mineralogically. These show that Al is present in the amorphous phase and not in a distinct aluminosilicate mineral. The electron microprobe analyses show zonation of the aluminum concentration, which correlates with the concentration of sodium and potassium. One of the Ohaaki scales (SP3 2011) was used in a flow-through experiment at 100 – 250 °C and pressures slightly above saturated water vapor pressure, using distilled water. Measured solu

Abstract:
Corrosion resistance alloys (CRAs) used in oil and gas industry may suffer severe localized corrosion such as pitting and crevice corrosion. Critical pitting temperatures (CPT) determined by ASTM G48-03 and ASTM G150-99 standard procedures are suitable for ranking the susceptibility of stainless steel to pitting corrosion but not appropriate for predicting pitting corrosion of stainless steel under production conditions. Some researchers have proposed the use of electrochemical noise (ECN) to estimate values of CPT on stainless steel. However the criteria used to determine these values are not

Abstract:
Abstract Dissolved oxygen in boiler systems is known to cause corrosion. Mechanical deaeration removes the majority of the dissolved oxygen while oxygen scavengers remove the remaining trace level. Sodium sulfite is a commonly used scavenger, but has several use limitations, such as high solids contribution to boiler water and decomposition products that are corrosive gases which can cause downstream equipment problems. A novel sulfite replacement oxygen scavenger has been developed which addresses the limitations of sulfite. Identification and demonstrated performance of the new scavenger is

Abstract:
Abstract Hydrogen Induced Cracking (HIC) is a major issue for line pipe steels exposed to sour environments. In general, 5.0 wt% NaCl and 0.5 wt% CH3COOH solution with 0.1 MPa H2S provided by NACE TM0284 as solution A is used to evaluate the HIC resistance of steel products. However, in many cases, the test condition is too severe compared to the actual field conditions. Therefore, establishment of an appropriate HIC evaluation method under mildly sour conditions has been the subject of considerable investigations in recent years. In this study, the influences of balance gas (N2 and CO2) and s

Abstract This paper will provide information on the standards used in evaluating and determining correct application and selection of protective coatings and linings used in the wastewater industry. It will also highlight certification that can be used in evaluating contractors and inspection companies used in the coating and lining process. A city of 100,000 people requires 10 to 20 million gallons of water daily. The resulting wastewater produced daily contains 20 to 60 tons of solids. In treatment facilities processing these large quantities of water and wastewater, concrete is exposed to a

Abstract:
Abstract A common method of corrosion control of buried pipeline is that of cathodic protection involving the use of sacrificial anodes. To ensure maximum effectiveness of an anode, a suitable backfill material of Gypsum/Bentonite is required to maintain the necessary current flow. This material is generally inert and moisture retentive. In the River Project of Libya, the bentonite used was collected from two different clay member formations. The destructive inspection of zinc anodes revealed that the backfill material used from one formation (No. 1) has dried quickly and shrunk away from the
