Inferring the Phylogeny of Bovidae Using Mitochondrial DNA Sequences: Resolving Power of Individual Genes Relative to Complete Genomes

Molecular techniques that assess biodiversity through the analysis of a small segment of mitochondrial genome have been getting wide attention for inferring the mammalian diversity. Due to their highly conserved nature, specific mitochondrial genes offer a promising tool for phylogenetic analysis. However, there is no established criteria for selecting the typical mitochondrial DNA (mtDNA) segments to achieve a greater resolving power. We therefore chose the family Bovidae as a model and compared the tree-topologies resulting from the commonly used and phylogenetically-informative genes including 16S rRNA, 12S rRNA, COI, Cyt b and D-loop with respect to complete mitochondrial genome. The tree topologies from the whole mitochondrial genome of 12 species were not identical albeit similar with those resulting from the five individual genes mentioned above. High bootstrap values were observed for mtDNA compared with that of any single gene. The average pair-wise sequence divergence using different genetic modes was found to be: D-loop (0.229) > Cyt b (0.159) > COI or complete mtDNA (0.143) > 12S rRNA (0.094) > 16S rRNA (0.091). The tree resulting from complete mtDNA clearly separated the 12 taxa of Bovidae into 3 major clusters, one cluster each for subfamily Cervinae and Bovinae and the third cluster comprised the distinctive clades of Caprinae and Antilopinae. However, jumping clades of Antilopinae were observed while using the individual genes. This study showed that Bison bison and Bos Taurus have very close phylogenetic relationship compared to Bubalus bubalis (Bovinae), irrespective of the method used. Our findings suggest that complete mtDNA genome provides most reliable understanding of complex phylogenetic relationships while the reliability of individual gene trees should be verified with high bootstrap support

Integration of renewable energy resources into the distribution network : a review on required power quality

Power quality is the critical element of modern power system network where more and more distributed energy resources (DER) can be found. Distributed generation, generates electricity from many small DER particularly from renewable sources. Distributed generator (DG) within the network from renewable energy resources (RER) like solar and wind, bring significant challenges to maintain acceptable power quality (PQ) at the consumer end. This paper investigates PQ issues associated with RER. It reviews existing PQ standards for distribution network (DN) and also summarized the experiences of several Distributed Network Service Provider (DNSP) while integrating DGs into the grid. It was found that few PQ parameter ranges varies in different standards due to lack of harmonization and that may hinder to accept bulk renewable energy into the grid

Estimation of energy storage and its feasibility analysis

Storage significantly adds flexibility in Renewable Energy (RE) and improves energy management. This chapter explains the estimation procedures of required storage with grid connected RE to support for a residential load. It was considered that storage integrated RE will support all the steady state load and grid will support transient high loads. This will maximize the use of RE. Proper sized RE resources with proper sized storage is essential for best utilization of RE in a cost effective way. This chapter also explains the feasibility analysis of storage by comparing the economical and environmental indexes

Significance of storage on solar photovoltaic system : a residential load case study in Australia

Energy storage is an essential part in effective utilization of Renewable Energy (RE). Most RE sources cannot provide constant energy supply and introduce a potential unbalance in generation and demand, especially in off-peak periods when RE generates more energy and in peak period when load demand rises too high. Storage allows intermittent sources like solar Photovoltaic (PV) to address timely load demand and adds flexibility in load management. This paper analyses the significance of storage for residential load considering solar PV as RE generator. The significance of storage was evaluated in off-grid or stand alone and grid connected configurations. Moreover it outlined the significance of storage in terms of environment and economics by comparing the Renewable Fraction (RF), Greenhouse Gas (GHG) emission, Cost of Energy (COE) and Net Present Cost (NPC). Investigation showed that storage has positive influences on both (off-grid and grid connected) configurations by improving PV utilization. It was found that in grid connected configuration storage reduced 46.47% of GHG emission, reduced COE, NPC and improved RF compared to the system without storage

Atypical Localizations of Hydatid Disease: Experience from a Single Institute

Introduction: The hydatid disease most often involves the liver and the lungs. The disease can involve any part of the body except the hair, teeth and nails. Primary extrahepaticopulmonary hydatid cysts are rare and only a few sporadic cases have been reported. Materials and Methods: Two hundred and forty-four patients with hydatid cysts managed surgically from January 2005 to December 2009 were evaluated retrospectively. Fourteen (5.7%) patients had isolated involvement of the atypical sites, while six (2.4%) also had a primary involvement of liver. Results: The cysts were present in gall bladder (0.4%), peritoneum (1.6%), spleen (1.6%), ovary (0.4%), subcutaneous (0.8%), seminal vesicle (0.4%), spinal (0.4%), pancreas (0.4%), kidney (0.4%), mediastinal (0.4%), muscle (0.4%), and brain (0.8%). Discussion and Conclusions: Involvement of sites other than liver and lungs by hydatid disease is rare. Symptoms are related to size, location or possible complication of the cyst. It should be strongly suspected in differential diagnosis of all abdominal cysts especially in an endemic area. Proper surgical and medical management to avoid any recurrences, and a regular follow-up, are of utmost importance to detect any late complications such as local recurrence of the disease and development of hydatidosis at the primary sites.Keywords: Atypical locations, hydatid, echinococcosisNigerian Journal of Surgery, Jan-Jun 2012 | Volume 18 | Issue

MIMAP Synthesis Report: Major Conclusions and Policy Implications

Despite the imperfections and complications in the evaluative procedures, the effects of SAP have been assessed in many developing countries. Research carried out by the PIDE-based project “Micro Impact of Macro Adjustment Policies” (MIMAP)1 is a pioneering venture that assesses the impact of various versions of SAP implemented by Pakistan since the mid-1980s. The general objective of the MIMAP project has been to facilitate the formulation of policies aimed at growth and improved welfare levels particularly of vulnerable groups, in Pakistan. The three specific objectives include: (1) To highlight and quantify the impact of macroeconomic and adjustment policies on poverty levels thereby yielding policy relevant insights; (2) To achieve the above specific objective through the use of sample household survey, the use of existing secondary socio-economic data sources, and the development of a micro-macro modelling exercise; and (3) To disseminate the project’s results within the country and to other MIMAP groups through technical publications, policy papers and seminars. In order to operationalise these objectives, the project was divided into two integrated but stand-alone components: poverty monitoring and modeling. Under the poverty-mentoring component, a nationally representative survey was carried out, while the modeling component was designed to develop Social Accounting Matrix (SAM) and Computable General Equilibrium Models (CGE). During the first phase of the Pakistan MIMAP project in total 13 studies were completed. The present study brings out major conclusions and policy implications based on these studies. It also sets out future direction for research. The sample design of the household survey and its socio-economic and demographic characteristics are discussed in Section II, where a comparison has also been made with the results of the 1998-99 Pakistan Integrated Household survey. Four research studies representing first round of analysis of the MIMAP data set are briefly summarised in Section III. Findings of five studies covering SAM and CGE models are discussed in Section IV, followed by presentation of findings of other three studies in Section V. The next section contains some suggestions for extension of research and modeling efforts to realise the objectives of ongoing MIMAP project. Conclusions and policy implications are presented in the last two section of the report
