Pharmacoinvasive Strategy vs. Primary PCI in STEMI: A Prospective Registry in a Large Geographical Area

ABSTRACT. Morphology, characterization, and geographical distribution of Blechnum cordatum (Blechnaceae-Pteridophyta). Specimens of Blechnum cordatum from localities of its large geographical area were analized. The species grows in Mesoamerica, Antillas and South America, from Venezuela and Colombia to Bolivia, SE and centre of Brazil, Paraguay, Argentina, centre and S of Chile, and Juan Fernández Islands. Blechnum cordatum is a tolerant, not vulnerable species, with large sporophytes; erect, scaly rhizomes; dimorphic fronds with scaly stipes and axes; lanceolate sterile laminae with lanceolate to oblong, coriaceae, finely denticulate to serrate, superficially scaly and hairy, attached by costa (peciolulate) pinnae, with cuneate- truncate to subcordate or auriculate bases, and narrowly lanceolate fertile laminae with vegetative tissue of pinnae reduced to the portion which support the undulate to erose indusia and continuous coenosorus. Veins are free, simple, geminate and furcate, the latter ramdomly dividing at different distances from the costa, all ending in large, active hydathodes. Aerophores, located only at the base of pinnae, may be absent. Spores have a cristate-reticulate perispore with filiform, ramified processes, and a smooth to granulate exospore. Based on this study, a new description of Blechnum cordatum, and its taxonomy is presented, along with comments on affinities with other neotropical and paleotropical species of the genus.Key words. Blechnaceae, Blechnum cordatum, morphology, taxonomy, palynology, geographical distribution.RESUMEN.

The Masses

Education has been the greatest tool for human resources development. The advances in information and communication technology has brought out a paradigm shift in the educational sector by making it more accessible, relevant, qualitative, and equitable for the masses. The use of satellite technology like INTELSAT, PEACESAT, and ATS in education has enhanced the opportunities for learners to acquire new skills (Moore & Kearsley, 1996). Both on-campus and distance mode students can be benefited by it. The satellite technology can serve a large geographical area. It allows audio and video signals uplinked from a station to be received to any number of downlink earth stations (Willis, 1995). Oliver (1994) reported that the transmission costs do not increase with the increase in the number of downlink stations. Satellite Instructional Television Experiment (SITE), one of the India’s early experiments conducted during 1975 to 1976, produced and transmitted 150 different science programs of 10 to 12 minutes duration, offering them to more than 2,330 villages in six geographical clusters. According to Shrestha (1997) and Govindaraju and Banerjee (1999), this experiment demonstrates the effectiveness of satellite communication for educational purposes.

The Impact

This paper tries to shift the focus of research on the impact of natural disasters on economic growth from global and national levels to sub-national levels. Inadequate sub-national level information is a significant lacuna for planning spatially targeted climate change adaptation investments. A fixed-effect panel regression analyses of 19 states from 2001 to 2015 assess the impacts of exposure to floods and droughts on the growth of gross state domestic product (GSDP) and human development index (HDI) in India. The flood and drought exposure are estimated using satellite data. The 19 states comprise 95% of the population and contribute 93% to the national GDP. The results show that floods indeed expose a large area, but droughts have the most significant impacts at the sub-national level. The most affected GSDPs are in the non-agriculture sectors, positively by the floods and negatively by droughts. No significant influence on human development may be due to substantial investment on mitigation of flood and drought impacts and their influence on better income, health, and education conditions. Because some Indian states still have a large geographical area, profiling disasters impacts at even smaller sub-national units such as districts can lead to effective targeted mitigation and adaptation activities, reduce shocks, and accelerate income growth and human development.

Multiple Clusters

The genus Lecanorchis Blume (1856: 188) comprises a group of mycoheterotrophic species that grow in multiple clusters with an erect, branched or unbranched stem (Hashimoto 1990, Sawa et al. 2006, Seidenfaden 1978, Szlachetko & Mytnik 2000). The key characteristic of the species of Lecanorchis is the presence of a calyculus, a cup-like structure between the base of the perianth and the apex of the ovary (Cameron 2003, Hashimoto 1990, Sawa et al. 2006). There are about thirty species and/or varieties in the genus Lecanorchis extending across a large geographical area that includes Thailand, Malaysia, Indonesia, Vietnam, the Philippines, Taiwan, Japan, and New Guinea (Hashimoto 1990, Seidenfaden 1978, Su 2000, Szlachetko & Mytnik 2000, Cameron 2003, Averyanov 2011). Precise identification of the Lecanorchis species is often difficult due to close similarities in morphology and the short durations of flowering periods (Hashimoto 1990, Averyanov 2005, Suddee & Pedersen 2011, Tsukaya & Okada 2013). Furthermore, detailed descriptions are lacking for some species, particularly those described in decades past. Given such difficulties in precise identification, adequate taxonomic studies of this genus have not been conducted.

AbstractSharīʿa court records are among the most important sources available for the social, economic and cultural history of the Ottoman empire and its provinces, especially from the sixteenth century onwards. These records contain invaluable material on diverse subjects such as economic consumption, agrarian relations, personal status, social stratification, crime and local politics. While covering a large geographical area and spanning several centuries, these records are often regarded by researchers as a single, homogeneous source and treated as a simple account of facts.In this essay, I argue that Sharīʿa court records are a complex source and that researchers should be cautious about accepting the information they contain at face-value. From their questionable statistical representation of society to their biased representation of Islamic law and order, these records defy categorization as simple reflections of reality. Comparisons between different geographical areas and time periods — and to fieldwork carried out in contemporary Sharīʿa courts, demonstrate the potential distance between the records and the reality they purportedly convey.

The Greedy Algorithm

Search and tracking is the problem of locating a moving target and following it to its destination. In this work, we consider a scenario in which the target moves across a large geographical area by following a road network and the search is performed by a team of unmanned aerial vehicles (UAVs). We formulate search and tracking as a combinatorial optimization problem and prove that the objective function is submodular. We exploit this property to devise a greedy algorithm. Although this algorithm does not offer strong theoretical guarantees because of the presence of temporal constraints that limit the feasibility of the solutions, it presents remarkably good performance, especially when several UAVs are available for the mission. As the greedy algorithm suffers when resources are scarce, we investigate two alternative optimization techniques: Constraint Programming (CP) and AI planning. Both approaches struggle to cope with large problems, and so we strengthen them by leveraging the greedy algorithm. We use the greedy solution to warm start the CP model and to devise a domain-dependent heuristic for planning. Our extensive experimental evaluation studies the scalability of the different techniques and identifies the conditions under which one approach becomes preferable to the others.

Early Pottery

Abstract Organic-tempered pottery is considered characteristic for the early pottery assemblages in most parts of Southwest Asia and Southeast Europe. The aim of the present paper is to explore: (a) the chronological consistency of this practice, i.e. is it always related to the early assemblages and how intensively was it employed by the various communities? and (b) is its use related to vessel type, surface treatment etc. and how does this change in time and space? In order to address these questions we explore the distribution patterns of this practice in this large geographical area, based on published information, since the appearance of pottery in the Near East until the early sixth millennium in Southeast Europe. Moreover, in the case of the Early Neolithic in Greece, new data is presented on the appearance and distribution of organic-tempered pottery within the assemblages of six newly studied sites in northern Greece, spanning the second half of the seventh millennium BC and the beginning of the sixth millennium BC. The emerging picture indicates that the cultural practice of organic tempering was available in all of this area for almost a millennium, although the significations may have not remained unaltered, and variably embraced by the various Neolithic communities. As such, this study offers insights into the complex process of neolithisation, and at the same time contextualizes the appearance of organic-tempering in northern Greece, which includes some of the earliest Neolithic sites in Europe.

Plant Inspection

Australia is forecast to become the world’s largest exporter of liquefied natural gas (LNG) by 2018, and to date, $70 billion has been invested into the Queensland coal seam gas (CSG) industry. These projects consist of tens of thousands of wells, each with a local facility to separate water and gas. From the separation facility, CSG is transported to compression and dehydration stations and water treatment facilities through numerous networks. Spread over an extremely large geographical area, this huge asset count presents a significant challenge to operations and maintenance personnel. Within Australia, regulation requires operators to inspect new pressure containing assets within the first year of operation. Maintaining compliance with these regulations presents significant costs of finances, time and manpower for operators. Furthermore, travelling to these remote sites for inspection increases the risk of driving accidents, currently the number one safety risk for personnel. This paper will address these challenges and discuss potential strategies for the optimisation of plant inspection and maintenance management. We will discuss how Wood Group has delivered innovative solutions to operators utilising technical engineering expertise, operational experience, understanding business constraints and delivering maximum return on investment (ROI).

AbstractThe collection and analysis of air samples for the study of microbial airborne communities or the detection of airborne pathogens is one of the few insights that we can grasp of a continuously moving flux of microorganisms from their sources to their sinks through the atmosphere. For large-scale studies, a comprehensive sampling of the atmosphere is beyond the scopes of any reasonable experimental setting, making the choice of the sampling locations and dates a key factor for the representativeness of the collected data. In this work we present a new method for revealing the main patterns of air-mass connectivity over a large geographical area using the formalism of spatio-temporal networks, that are particularly suitable for representing complex patterns of connection. We use the coastline of the Mediterranean basin as an example. We reveal a temporal pattern of connectivity over the study area with regions that act as strong sources or strong receptors according to the season of the year. The comparison of the two seasonal networks has also allowed us to propose a new methodology for comparing spatial weighted networks that is inspired from the small-world property of non-spatial networks.
