Operational Error

Within the framework of Cognitive Translation Theory, the paper aims to explore how students of science who do not specialize in English use and acquire various kinds of knowledge in the process of translating a scientific text from Russian into English, focusing on the problems they encounter and the strategies they use in order to solve these problems. The study is based on the assumption that with the numerous sources of information available today many of the knowledge gaps both linguistic and non-linguistic can be filled provided the translator uses the right sources at the right moment. The paper uses data obtained from an experimental study carried out using the think-aloud protocols technique. The translation process is described in terms of the cognitive-heuristic approach to translation, using such terms as the cognitive context, cognitive search, and auto-correction. The paper uses the term ‘operational error’ to denote the wrong strategy employed by the translator, which leads to a breakdown in the process of translation and eventually to an unsuccessful translation variant. Various kinds of operational errors specific to students of science are discussed using examples from the protocols. Special attention is paid to the importance of translation on the conceptual level and the use of auto-correction to ensure the naturalness of the target text. The experimental data obtained also allow identifying the areas of English grammar that cause the most problems for students of science.

This research work on material selection for subsea pipeline construction was carried out to analyze and recommend suitable material option that satisfies DNV-OS-F101 standard for subsea pipeline constructions which will not succumb to extreme conditions and performs well in unpredictable conditions in the Niger Delta Region of Nigeria. Crude oil is mainly transported through pipelines, structural failure of the pipelines will severely affect oil production processes and will cause huge economic loss. Data on oil pipeline failures in the Niger Delta region of Nigeria were gathered and the major causes were; corrosion, operational error, third party activities and mechanical failures which were associated with the construction materials and structures of the pipelines. Hence, material selection for subsea pipelines is of vital importance. This paper makes use of Technique for Order Preference by Similarity to the Ideal Solution (TOPSIS) Theory to make fuzzy evaluation of different material options for pipeline construction. Statistical data and experts’ knowledge were integrated in addressing data limitation. This paper utilizes related weights and normalized scores based on experts’ judgements and with the aid of value engineering (VE) method, material criteria based on DNV-OS-F101 standard and TOPSIS Theory to achieve the best material option. The analysis has demonstrated that the estimation of TOPSIS is reliable. The outcome obtained can be used to assist the decision maker in the selection of the best material option suitable for the construction of subsea pipeline in Niger Delta region.

Abstract A non-instrumented, single-use, affordable, and fully- yet safely-disposable DNA analysis system for Point Of Care (POC) diagnostic process has been proposed by integrating (1) a hydration-reactive mixture for a portable heating element as a powerless actuator, (2) commercially available optical adhesive films as valves, and (3) an exothermic reaction-based recombinant polymerase amplification (RPA) process for non-instrumented DNA amplification. The operational error tolerance of the adhesive valves was evaluated by gas production and long-lasting ability, and the amplification performance of the RPA device was validated by gel electrophoresis. Finally, a DNA analysis device was fabricated and tested based on a hydration reaction with a DNA extraction microfluidic channel and an exothermic reaction-based RPA device. In the DNA extraction process, dimethyl adipimidate (DMA) solution was used to eliminate some required injection steps from the extraction process. The integrated system's functionality was successfully demonstrated, and the suggested system could become a foundation for the ultimate total solution for POC DNA analysis.

Operational Error

Petroleum is transported across the water in barges and tankers, and on land, using pipelines, trucks, and trains. Natural gas is moved, mainly, by pipelines. The most common causes of tanker accidents are: fire/explosions, loading/offloading, structural damage, collision, and grounding. Pipeline accidents are due to: corrosion, third parties activities, mechanical damage, natural events, and operational error. Some of the most commonly applied preventive activities that reduce spills in waterborne transportation are: double-hulled tanker, navigation safety and radio communications equipment, tanker exclusion zone, etc. The pipeline condition can be recorded by using various nondestructive measurement techniques or by chemical analysis of fluid flows. Different types of sensors can be used to locate and determine the size of an anomaly in the pipeline geometry. Mayor methods for detecting leaks are measuring the hydrodynamic parameters or registering abnormal conditions in the fluid flow and detecting phenomena in the immediate vicinity of the pipeline.

The purpose of this research is to fabricate bio-model that based on Rapid Prototyping technology which is by using Fused Deposition Modeling (FDM) and designing an implant by using a Computer Aided Design technology. A case study from Hospital Kuala Lumpur which is the maxillofacial will be fabricated by using FDM technique. The completed 3D prototype or biomodel will be analyzed to makes the result more truthful in terms of the dimensional accuracy, operational error and cost analysis. Computer aided design technology is used to design the customized implant in order to replace the fractured maxilla part.

Abstract Objectives.—To identify errors in surgical pathology practice that lead to malpractice claims, and to define the frequency and severity of pathology malpractice claims and discuss the implications. Design.—Three hundred seventy-eight pathology malpractice claims reported to The Doctors Company of Napa, Calif, between 1998 and 2003, were reviewed. Nuisance claims and autopsy claims were excluded; the 335 remaining claims were analyzed. Results.—Pathology claim frequency is low. Pathology claim severity is high, especially for claims involving a misdiagnosis of melanoma or a false-negative Papanicolaou test. Fifty-seven percent of claims involved the following 5 categories: breast specimens, melanoma, Papanicolaou smears, gynecologic specimens, and operational error. Sixty-three percent of claims involved failure to diagnose cancer, resulting in delay in diagnosis or inappropriate treatment. Conclusion.—A false-negative diagnosis of melanoma is the single most common reason for filing a malpractice claim against a pathologist. Nearly one third of misdiagnoses involve melanoma misdiagnosed as Spitz nevus, “dysplastic” nevus, spindle cell squamous carcinoma, atypical fibroxanthoma, and dermatofibroma.
