Generically, SCM may be said to include all activities carried out to ensure proper functioning of the supply chain. The activities included in proper management of a supply chain broadly include logistics activities, planning and control of the flow of information and materials in a firm, management of relationships with other organizations and government intervention, however, crude oil theft and pipeline vandalism are established products supply chain disruptors in Nigeria which are rendering the task of running an efficient petroleum supply chain onerous. This paper aims to establish the importance of effective supply chain strategies for companies in the oil and gas industry with special focus on the Nigerian oil and gas sector and the strategies by which the state oil and gas corporation in this sector may mitigate disruptions to its supply chain. This study investigates the enhancement of supply chain strategies towards meeting the challenge of crude oil theft and pipeline vandalism, using the Nigerian National Corporation (NNPC) as a case study. Based on this study, data were collected from two sources: A summary of incident reports obtained from NNPC and an interview with personnel in the PPMC Department. Incident report refers to a report produced when accidents such as equipment failure, injury, loss of life, or fire occur at the work site. Content analysis is utilized to evaluate data obtained from interview responses, CBN financial stability reports, NDIC annual reports, circulars, banking supervision reports and implementation guidelines. The study found out that NNPC should endeavor to sustain its value chain and ward of pipeline vandals and crude oil thieves by engaging in community partnership, detailing security outfits to ensure its pipelines’ right of way and bridging. Concluded that the oil supply chain of the Nigerian National Petroleum Corporation has been plagued by disruptions in the form of crude oil theft and pipeline vandalism which has h

Palaeogeography of a shallow carbonate platform:The case of the Middle to Late Oxfordian in the Swiss Jura Mountains

Journal of Palaeogeography 2015年第3期4卷 251-268页

The Oxfordian （Late Jurassic） carbonate-dominated ptatform outcropping in the Swiss Jura Mountains offers a good biostratigraphic, sequence-stratigraphic, and cyclostratigraphic framework to reconstruct changes in facies distribution at a time-resolution of 100 ka. It thus allows interpreting the dynamic evolution of this platform in much more detail than conventional palaeogeographic maps permit. As an example, a Middle to Late Oxfordian time slice is presented, spanning an interval of about 1.6 Ma. The study is based on 12 sections logged at cm-scale. The interpreted depositional environments include marginal-marine emerged ;ands, fresh-water lakes, tidal fiats, shallow lagoons, ooid shoals, and coral reefs. Although limestones dominate, marly intervals and dolomites occur sporadically. Major facies shifts are related to m-scale sea-level changes linked to the orbital short eccentricity cycle （100 ka）. The 20-ka precession cycle caused minor facies changes but cannot always be resolved. Synsedimentary tectonics induced additional accommodation changes by creating shallow basins where days accumulated or highs on which shoals or islands formed. Autocyclic processes such as lateral migration of ooid and bioclastic shoals added to the sedimentary record. CEimate changes intervened to control terrestrial run-off and, consequently, siliciclastic and nutrient input. Coral reefs reacted to such input by becoming dominated by microbialites and eventually by being smothered. Concomitant occurrence of siliciclastics anddolomite in certain intervals further suggests that, at times, it was relatively arid in the study area but there was rainfall in more northern latitudes, eroding the hercynian substrate. These examples from the Swiss Jura demonstrate the highly dynamic and （geologically speaking） rapid evolution of sedimentary systems, in which tectonically controlled basin morphology, orbitally induced climate and sea-level changes, currents, and the ecology of the carbon

h-FABP in Pre Capillary Pulmonary hypertension: Comparison to Other Surrogate Parameters for Prediction of Severity and Outcome

引用

Open Journal of Respiratory Diseases 2011年第1期1卷 1-13页

Background: heart-type fatty acid-binding protein (h-FABP) is a promising novel biomarker for risk stratification of patients with chronic thromboembolic pulmonary hypertension (CTEPh). Whether disease severity in a group of patients with pre capillary pulmonary hypertension (Ph) can be predicted by determination of plasma h-FABP levels remains unknown. Methods: 41 consecutive patients with a mean (±SD) age of 60.6 ± 2.1 years and severe Ph were studied with a mean follow up to 541 days (95% CI: 420;661 days). h-FABP, but also the biomarkers NT-Pro-BNP and big-endothelin (Big-ET1), were correlated to parameters derived from right sided cardiac catheterization and cardio-pulmonary exercise test. Results: At baseline h-FABP levels ranged from 620 to 15200 pg/ml (3648 ± 502 pg/ml) and were weakly but significantly correlated to VO2AT (r = –0.37, p = 0.04) and VO2 peak (r =–0.38, p = 0.03). however, invasively measured hemodynamic parameters of Ph and right ventricular dysfunction did not correlate with h-FABP levels. In- terestingly, moderate to high correlations between h-FABP and NT-Pro-BNP (r = 0.51, p = 0.01) and Big-ET1 (r = 0.65, p = 0.01) and between Big-ET1 and NT-Pro-BNP (r = 0.5, p = 0.01) could be observed. In contrast to h-FABP, NT-Pro-BNP, and even more Big-ET1, showed significant correlations to different invasively measured hemodynamic parameters of the disease indicating severity and consequently prognosis of severe pre-capillary pulmonary hypertension. however, in a multivariate Cox regression analysis, PVR, mixed venous oxygen saturation and the VE/VCO2 slope (>60) as well as the heart rate recovery within one minute (hRR) but none of the biomarkers were identified as independent factors of poor prognosis. In con- trast, peak workload and mixed venous saturation were identified as risk markers in the idiopathic pulmonary arterial hypertension subgroup. Conclusions: In contrast to the predictive value of h-FABP in CTEPh h-FABP fails to be a reliable ma

In this paper, the authors explore the potential of several popular equalization techniques while overcoming their disadvantages. First, extensive literature survey on equalization is conducted. The focus is on popular linear equalization algorithms such as the conventional least mean square (LMS ) algorithm, the recursive least squares ( RLS ) algorithm, the filtered X LMS algorithm and their development. To overcome the slow convergence problem while keeping the simplicity of the LMS based algorithms, an h 2 optimal initialization is proposed.
