Frequency response analysis (FRA) is regarded as the most effective technique to detect mechanical faults of transformers. Over the years, FRA measurement data have been collected by utilities into transformer asset databases. The characteristic of FRA data is fundamentally determined by the transformer's equivalent electrical circuit, which consists of inductance and capacitance parameters that are windings' design and structure dependent. Different winding types tend to have different FRA characteristics, and a transformer's design information such as winding type, dimension etc. is often not known to the utility but critically important for asset management. This study reviews the state-of-the-art transformer FRA databases and application of machine learning techniques in this field, and proposes to apply a support vector machine (SVm) model onto the FRA data to identify the winding type. The SVm model is first trained by FRA traces of transformers with known winding types, and after testing, the SVm model is then applied to FRA traces with unknown winding information. A set of data from the UK's National Grid FRA database, was used to demonstrate and verify the SVm model. All transformers used in this study are 400/275/13 kV transmission transformers, which were designed using four different winding types, namely multiple layer, plain disc, interleaved disc and single helical windings. The proposed method can successfully identify the correct winding type.

metformin is a common diabetes drug that may reduce lactate clearance by inhibiting mitochondrial oxidative phosphorylation,leading to metforminassociated lactic acidosis(mALA).As diabetes mellitus is a common chronic metabolic condition found in critically ill patients,pre-existing metformin use can often be found in critically ill patients admitted to the intensive care unit or the high dependency *** aim of this narrative mini review is therefore to update clinicians about mALA,and to provide a practical approach to its diagnosis and *** in critically ill patients may be suspected in a patient who has received metformin and who has a high anion gap metabolic acidosis,and confirmed when lactate exceeds 5 mmol/*** factors include those that reduce renal elimination of metformin(renal impairment from any cause,histamine-2 receptor antagonists,ribociclib)and excessive alcohol consumption(as ethanol oxidation consumes nicotinamide adenine dinucleotides that are also required for lactate metabolism).Treatment of mALA involves immediate cessation of metformin,supportive management,treating other concurrent causes of lactic acidosis like sepsis,and treating any coexisting diabetic *** mALA requires extracorporeal removal of metformin with either intermittent hemodialysis or continuous kidney replacement *** optimal time to restart metformin has not been *** is nonetheless reasonable to first ensure that lactic acidosis has resolved,and then recheck the kidney function post-recovery from critical illness,ensuring that the estimated glomerular filtration rate is 30 mL/min/1.73 m^(2) or better before restarting metformin.

Three long-term field trials in humid regions of Canada and the USA were used to evaluate the influence of soil depth and sample numbers on soil organic carbon (SOC) sequestration in no-tillage (NT) and moldboard plow (mP) corn (Zea mays L.) and soybean (Glycine max L.) production systems. The first trial was conducted on a maryhill silt loam (Typic Hapludalf) at Elora, Ontario, Canada, the second on a Brookston clay loam (Typic Argiaquoll) at Woodslee, Ontario, Canada, and the third on a Thorp silt loam (Argiaquic Argialboll) at Urbana, Illinois, USA. No-tillage led to significantly higher SOC concentrations in the top 5 cm compared to mP at all 3 sites. However, NT resulted in significantly lower SOC in sub-surface soils as compared to mP at Woodslee (10-20 cm, P = 0.01) and Urbana (20-30 cm, P more SOC storage than mP at the Elora site (3.3 mg C ha-1) and at the Woodslee site (6.2 mg C ha-1) on an equivalent mass basis (1350 mg ha-1 soil equivalent mass). Similarly, NT had greater SOC storage than mP at the Urbana site (2.7 mg C ha-1) on an equivalent mass basis of 675 mg ha-1 soil. However, these differences disappeared when the entire plow layer was evaluated for both the Woodslee and Urbana sites as a result of the higher SOC concentrations in mP than in NT at depth. Using the minimum detectable difference technique, we observed that up to 1500 soil sample per tillage treatment comparison will have to be collected and analyzed for the Elora and Woodslee sites and over 40 soil samples per tillage treatment comparison for the Urbana to statistically separate significant differences in the SOC contents of sub-plow depth soils. Therefore, it is impracticable, and at the least prohibitively expensive, to detect tillage-induced differences in soil C beyond the plow layer in various soils.

提出一种基于能量守恒原理的纵联差动保护,对线路两端或母线各端的有功功率进行比较,若各端功率的和超出整定值,则判定为区内故障。在典型400 kV输电系统模型上,运用mATLAB仿真软件对所提出的原理进行了仿真验证。仿真结果表明,该方法比传统电流比率差动保护更加可靠且计算量小,因而可缩短动作时间。该方法能检测所有故障类型,适应于超高压远距离输电线路。
