The social impacts of stormwater management techniques
This paper presents the results of research into the social impacts of stormwater management techniques applied within urban environments. The main aim of the study was to compare public and professional attitudes of stormwater management practices such as Sustainable Urban Drainage Systems (SUDS) and river management techniques. Any new and innovative technology used in residential areas, besides being economically and environmentally acceptable, must also be accepted by the residents. There has been considerable interest in the assessment of the public perception of SUDS in the UK by consultants, developers, the Environment Agency of England and Wales as well as by the Scottish Environment Protection Agency (SEPA). This research was undertaken to inform such interest and also to obtain a more holistic view of the perception by professionals of SUDS. A comparative study of the perceptions of river management in three densely populated European cities facing similar storm water management problems was carried out. The selected cities were Glasgow in Scotland – U. K., an area in west London, England - U.K., and part of Athens – Greece. All sites were located within flood-prone suburban areas, and different river management techniques have been proposed or adopted

The reported thoracic injuries in Homer's Iliad
Homer's Iliad is considered to be a prominent and representative work of the tradition of the ancient Greek epic poetry. In this poem Homer presents the battles which took place during the last year of the 10-year lasting Trojan War between Achaeans and Trojans. We wanted to examine the chest wounds, especially those which are described in detail, according to their localization, severity and mortality. Finally, there are reported 54 consecutive thoracic injuries in the Iliad. The mostly used weapons were the spear (63%), the stones (7.4%), the arrow (5.5%) and the sword (5.5%). We divided the injuries according to their severity in mild (those which did not cause serious injury to the victim), medium (those which cause the victim to abandon the battlefield), and severe (those which cause death of the victim). According to this classification, the reported injuries were mild in 11.11%, medium in 18.52%, and severe in the last 70.37% of the reported cases. In other words, 89% of the injuries belong to the medium or severe category of thoracic injury. As far as the mortality of the injuries is concerned, 38 out of 54 thoracic injuries include death, which makes the mortality percentage reach 70.37%. Concerning the "allocation of the roles", the Achaean were in 68% perpetrators and the Trojans in only 32%. In terms of gravity, out of 38 mortal injuries 30 involve a Trojan (78.95%) and the remaining 8 an Achaean (21.05%). The excellent and detailed description of the injuries by Homer, as well as of the symptoms, may reveal a man with knowledge of anatomy and medicine who cared for the injured warriors in the battlefield
The social dimension of stormwater management practices including sustainable urban drainage systems and river management options
Under what conditions, if any, should be abortion legally permissible
CHAPTER I: INTRODUCTION
Our society is often divided between good and evil, right and wrong. However, the distinction between the two is not always that self-evident or can be taken light-heartedly. The issue I will address here qualifies as one of the most polarizing issues, whether abortion should be legally permissible and if so, under what conditions.
Posing this question we see people covering the whole strictness spectrum of either abortion-supporting or abortion-condemning groups, advocating their stances, based on arguments that they find concrete enough to win the “contest” and prevail against their adversaries. What are the questions we should ask to judge the legality of abortion? In my thesis I will discuss biology and embryology arguments, as well as arguments about the moral status of the fetus, ethics and the moral framework of abortion. Not limited to that I will address what are the legal rights of the mother and the fetus respectively should be. I will briefly refer to the Law but I will approach the legality of abortion through philosophical argumentation and the role of the state. Through the literature and my personal argumentation I will show why abortion should be legally impermissible with the exception of situations where the life of the mother is at stake both in physical and mental sense, when the burden of the pregnancy is humongous evolution or where severe fetal deformities will lead to a painful and devastating life of the fetus assuming it will be even born in the first place. Other exceptions apply for the situations of rape and incest and generally situations of coercion; both physical and mental
Nonlinear translational symmetric equilibria relevant to the L-H transition
Nonlinear z-independent solutions to a generalized Grad-Shafranov equation
(GSE) with up to quartic flux terms in the free functions and incompressible
plasma flow non parallel to the magnetic field are constructed
quasi-analytically. Through an ansatz the GSE is transformed to a set of three
ordinary differential equations and a constraint for three functions of the
coordinate x, in cartesian coordinates (x,y), which then are solved
numerically. Equilibrium configurations for certain values of the integration
constants are displayed. Examination of their characteristics in connection
with the impact of nonlinearity and sheared flow indicates that these
equilibria are consistent with the L-H transition phenomenology. For flows
parallel to the magnetic field one equilibrium corresponding to the H-state is
potentially stable in the sense that a sufficient condition for linear
stability is satisfied in an appreciable part of the plasma while another
solution corresponding to the L-state does not satisfy the condition. The
results indicate that the sheared flow in conjunction with the equilibrium
nonlinearity play a stabilizing role.Comment: 26 pages, 16 figure
Evaluating the performance of survey-based operational management procedures
The design and evaluation of survey-based management strategies is addressed in this article, using three case-study fisheries: North Sea herring, Bay of Biscay anchovy and North Sea cod, with a brief history and the main management issues with each fishery outlined. A range of operational management procedures for the case study stocks were designed and evaluated using trends that may be derived from survey indices (spawner biomass, year-class strength and total mortality) with an array of simple and more structured observation error regimes simulated. Model-free and model-based indicators of stock status were employed in the management procedures. On the basis of stochastic stock-specific simulations, we identified the following key determinants of successful management procedures: (i) adequate specification of the stock-recruit relationship (model structure, parameter estimates and variability), (ii) knowledge of the magnitude and structure of the variation in the survey indices, and (iii) explication of the particular management objectives, when assessing management performance. More conservative harvesting strategies are required to meet specified targets in the presence of increasing stochasticity, due to both process and observation error. It was seen that survey-based operational management procedures can perform well in the absence of commercial data, and can also inform aspects of survey design with respect to acceptable levels of error or bias in the surveys
