Analysis of Nigerian Electricity Generation Multi Year Tariff Order Pricing Model

Energy and Power Engineering 2017年第10期9卷 541-554页

作者： Nnamdi B. Anosike Jude E. Dara Ugochukwu C. Ngwaka frances O.

The Multi Year Tariff Order (MYTO) is the Nigerian Electricity Regulatory Commission (NERC) pricing framework for determining the Nigerian Electricity supply Industry (NEsI) pricing model. One of the objectives of the NERC’s MYTO pricing model is to ensure regulated electricity end user tariff without compromising return on investment. Achieving this objective is imperative to attract investors in the growing Nigerian electricity market. However, NEsI has hitherto been faced with challenges ranging from its inability to provide sufficient power to its customers to not being viable enough to provide return on capital invested. In this paper, sensitivity analysis of power plant operation and performance parameters on the cost of electricity (CoE) generation using MYTO (power generation) pricing model were evaluated. Thermodynamic modeling and simulation of an open cycle gas turbine (OCGT) was carried out to augment scarce data on power plant performance and operation in Nigeria. sensitivity analysis was carried out using probabilistic method based on Monte Carlo simulation (MCs) implemented in commercial software (@ Risk®). The result highlighted sensitivity of the model input parameters to cost of electricity generation based on technical and financial assumptions of MYTO model. seven most influential parameters affecting generation cost were identified. These parameters and their correlation coefficients are given as: 1) foreign exchange rate, 0.76;2) cost of fuel, 0.51;3) thermal efficiency, -0.23;4) variable operation and maintenance cost, 0.22;5) fixed operating and maintenance cost, -0.03;6) capacity factor, -0.02;and 7) average capacity degradation, 0.01. Based on the gas turbine engine and input parameter distributions statistics for this study, the generation cost lies between 9.84 to 15.45 N/kWh and the probabilities of CoE within these values were established.

本文介绍一个可以用于研究遗传与环境互动的新颖方法。此研究收集了上千个4～10岁儿童的数据。这些儿童的出生都借助于不同的辅助受孕技术（Assisted Reproductive Technologies），包括试管婴儿、精子捐赠、卵子捐赠、胚胎捐赠及代孕技术。本项目通过妇科（助孕）医院收集被试的行为数据，包括家庭互动、养育方式、父母婚姻质量、家庭成员的心理健康及经济状况等。本文选择性地介绍一些分析的结果，以彰显这种设计在分离遗传和产前产后环境对儿童发展的贡献。首先，我们比较了“助孕”儿童与“自然孕”儿童在父母冲突、父母对子女敌意以及儿童抑郁症状之间关系的异同。其次，我们比较了这两组儿童在父母抑郁症状、家庭关系质量以及儿童抑郁症状之间关系的异同。再次，本文介绍了这一可分离遗传与环境因素的研究设计。最后，我们讨论了这一设计对发展心理病干预及预防的意义。

Community-Based Coral Reef Rehabilitation in a Changing Climate:Lessons Learned from Hurricanes,Extreme Rainfall,and Changing Land Use Impacts

Coral reefs have largely declined across multiple spatial scales due to a combination of local-scale anthropogenic impacts, and due to regional-global climate change. This has resulted in a significant loss of entire coral functional groups, including western Atlantic staghorn coral (Acropora cervicornis) biotopes, and in a net decline of coral reef ecosystem resilience, ecological functions, services and benefits. Low-tech coral farming has become one of the most important tools to help restore depleted coral reefs across the Wider Caribbean Region. We tested a community-based, low-tech coral farming approach in Culebra Island, Puerto Rico, aimed at adapting to climate change-related impacts through a two-year project to propagate A. cervicornis under two contrasting fishing management conditions, in coastal areas experimenting significant land use changes. Extreme rainfall events and recurrent tropical storms and hurricanes had major site-and method-specific impacts on project outcome, particularly in areas adjacent to deforested lands and subjected to recurrent impacts from land-based source pollution (LBsP) and runoff. Overall, coral survival rate in “A frame” units improved from 73% during 2011-2012 to 81% during 2012-2013. Coral survival rate improved to 97% in horizontal line nurseries (HLN) incorporated during 2012-2013. Percent tissue cover ranged from 86% to 91% in “A frames”, but reached 98% in HLN. Mean coral skeletal extension was 27 cm/y in “A frames” and 40 cm/y in HLN. These growth rates were up to 545% to 857% faster than previous reports from coral farms from other parts of the Caribbean, and up to 438% faster than wild colonies. Branch production and branchiness index (no. harvestable branches > 6 cm) increased by several orders of magnitude in comparison to the original colonies at the beginning of the project. Coral mortality was associated to hurricane physical impacts and sediment-laden runoff impacts associated to extreme rainfall and defores

Evaluation of the Nutritional status and Phytomedicinal Properties of Dried Rhizomes of Turmeric (<i>Curcuma longa</i>)

引用

Journal of Biosciences and Medicines 2020年第8期8卷 163-179页

作者： Victor Henry Azubuike Enemor Uchechukwu Chibuzo Ogbodo Ogechukwu frances Nworji Obiajulu Christian Ezeigwe Chukwuemeka Obumneme Okpala Gloria Chiamaka Iheonunekwu Department of Applied Biochemistry Nnamdi Azikiwe University Awka Nigeria

Turmeric (Curcuma longa) belongs to the family Zingiberaceae and has long been used traditionally for centuries as a spice and medicinal elixir. Hence, the present study aimed to profile the nutritional and phytomedicinal properties of the plant in order to justify its relevance in traditional phytomedicine and advocate its application in novel pharmacological products. Using standard methods (High Performance Liquid Chromatography, Gas Chromatography-Mass spectroscopy and Atomic Absorption spectrophotometry), the dried rhizomes were washed, pulverized and ethanol extracts subjected to proximate, phytochemical, vitamins, amino acid and mineral determinations. Data obtained were analyzed using student’s t-test in statistical Package for the social sciences version 21. Determined proximate indices indicated moisture content of 9.55%, carbohydrate (57.30%), ash (24.70%), crude fiber (1.12%), proteins (2.15%) and fat (5.32%). Mineral composition analyses showed that C. longa rhizomes had higher contents of calcium, magnesium, potassium and sodium in parts per million (ppm) at 38.68 ± 0.114, 19.75 ± 0.001, 9.20 ± 0.002 and 7.06 ± 0.014 respectively. Amino acid profile revealed the presence of both essential and non-essential types with aspartate and glutamate in higher contents at 9.78 g/100 g and 9.65 g/100 g, respectively. Findings showed also the presence of vitamins A, C and D at 254.5 ± 2.19 mg/kg, 19.47 ± 0.16 mg/kg and 10.92 ± 0.92 mg/kg, respectively. Phytochemical analyses showed the presence of phenolic compounds with high retention times. This study thus revealed that C. longa possesses various nutritional and pharmacological/medicinal components in considerable quantities and can provide the body with basic nutrients for its therapeutic needs as well as secondary compounds with tremendous phytomedicinal potentials.

AIM: To discuss the advantages of ultra-high field (7T) for 1H and 13C magnetic resonance spectroscopy (MRs) studies of ***: Measurements of brain metabolites were made at both 3 and 7T using 1H MRs. Measurements of glycogen and lipids in muscle were measured using 13C and 1H MRs ***: In the brain, increased signal-to-noise ratio (sNR) and dispersion allows spectral separation of the amino-acids glutamate, glutamine and γ-aminobutyric acid (GABA), without the need for sophisticated editing sequences. Improved quantification of these metabolites is demonstrated at 7T relative to 3T. sNR was 36% higher, and measurement repeatability (% coefficients of variation) was 4%, 10% and 10% at 7T, vs 8%, 29% and 21% at 3T for glutamate, glutamine and GABA respectively. Measurements at 7T were used to compare metabolite levels in the anterior cingulate cortex (ACC) and insula. Creatine and glutamate levels were found to be significantly higher in the insula compared to the ACC (P scle, the increased sNR and spectral resolution at 7T enables interleaved studies of glycogen (13C) and intra-myocellular lipid (IMCL) and extra-myocellular lipid (EMCL) (1H) following exercise and re-feeding. Glycogen levels were significantly decreased following exercise (-28% at 50% VO2 max; -58% at 75% VO2 max). Interestingly, levels of glycogen in the hamstrings followed those in the quadriceps, despite reduce exercise loading. No changes in IMCL and EMCL were found in the ***: The demonstrated improvements in brain and muscle MRs measurements at 7T will increase the potential for use in investigating human metabolism and changes due to pathologies.
