A stronger Dunford-Pettis property

We discuss a strong version of the Dunford-Pettis property, earlier named (DP*) property, which is shared by both l(1) and l(infinity) It is equivalent to the Dunford-Pettis property plus the fact that every quotient map onto c(0) is completely continuous. Other weak sequential continuity results on polynomials and analytic mappings related to the (DP*) property are shown.

A group topology on the free abelian group of cardinality c that makes its square countably compact

Under p = c, we prove that it is possible to endow the free abelian group of cardinality c with a group topology that makes its square countably compact. This answers a question posed by Madariaga-Garcia and Tomita and by Tkachenko. We also prove that there exists a Wallace semigroup (i.e., a countably compact both-sided cancellative topological semigroup which is not a topological group) whose square is countably compact. This answers a question posed by Grant.

HYPERBOLICITY OF SEMIGROUP ALGEBRAS II

In 1996, Jespers and Wang classified finite semigroups whose integral semigroup ring has finitely many units. In a recent paper, Iwaki-Juriaans-Souza Filho continued this line of research by partially classifying the finite semigroups whose rational semigroup algebra contains a Z-order with hyperbolic unit group. In this paper, we complete this classification and give an easy proof that deals with all finite semigroups.

Timelike Christoffel pairs in the split-quaternions

We characterize the Christoffel pairs of timelike isothermic surfaces in the four-dimensional split-quaternions. When restricting the receiving space to the three-dimensional imaginary split-quaternions, we establish an equivalent condition for a timelike surface in R(2)(3) to be real or complex isothermic in terms of the existence of integrating factors.

Trace element impurity determination in aspirin tablets by INAA

Instrumental neutron activation analysis (INAA) was applied to assess trace element concentrations in six samples of aspirin tablets acquired in SA o pound Paulo city, Brazil. Concentrations of the elements Br, Ca, Co, Cr, Fe, K, La, Na, Sc and Zn were determined. Comparisons were made between the results obtained with published data for aspirins from foreign countries. Certified reference materials, INCT-MPH-2 Mixed Polish Herbs were analyzed for quality control of the analytical results.

Förpackningsproduktion samt studie om hur reumatikervänliga förpackningar är idag

AssiDomän Frövi board mill has in cooperation with students from Graphic Technologyat the University of Dalarna a degree project that involves developing package solutionsin carton material from AssiDomän Frövi. This year the basic condition was to use theweights 270g/m2, 300g/m2 and 330g/m2 and choose between Frövi Bright, Frövi Lightand Frövi Carry.The packages were supposed to be in the segments industrial products,chocolate/sweets and beauty products/cosmetics. Two packages were produced in thesegments industrial products and beauty products/cosmetics.The first package, produced in the industrial segment, contains textile color and templatesand the second package is a gift package and contains nail polish.The investigation part of the project deals with how the packages today are fit forrheumatics in opening purpose.

Cold rolling mill thickness control using the cascade-correlation neural network

The improvements in thickness accuracy of a steel strip produced by a tandem cold-roIling mill are of substantial interest to the steel industry. In this paper, we designed a direct model-reference adaptive control (MRAC)  scheme that exploits the natural level of excitation existing in the closed-loop with a dynamically constructed cascade-correlation neural network (CCNN) as a controller for cold roIling mill thickness control. Simulation results show that the combination of a such a direct MRAC scheme and the dynamically constructed CCNN significantly improves the thickness accuracy in the presence of disturbances and noise in comparison with to the conventional PID controllers.

The prediction of damage condition in regards to damage factor influence of light structures on expansive soils in Victoria, Australia

This paper proposes a neural network model using genetic algorithm for a model for the prediction of the damage condition of existing light structures founded in expansive soils in Victoria, Australia. It also accounts for both individual effects and interactive effects of the damage factors influencing the deterioration of light structures. A Neural Network Model was chosen because it can deal with 'noisy' data while a Genetic Algorithm was chosen because it does not get `trapped' in local optimum like other gradient descent methods. The results obtained were promising and indicate that a Neural Network Model trained using a Genetic Algorithm has the ability to develop an interactive relationship and a Predicted Damage Conditions Model.

The pragmatics of text facilitation : the study of academic English of native and non-native writers

In this paper I describe the discursive strategies related to the writer–reader textual reciprocity. I focus on one way of achieving such reciprocity -- the employment by the writer of facilitative schematic structures and metalanguage where one text segment signposts information conveyed in the segment that follows. I refer to these facilitative schematic structures as "organising relational schemata". I see organising relations as the most explicit components of the rhetorical structure of texts: they illuminate the main message and aid the reader's cognitive processes in the orientation of how information is conveyed by text.
This paper discusses the way the choices of organising relations and associated metalanguage by the writers in different cultures and different discourse communities contribute to the communicative homeostasis in the world of text. It shows how the influence of a native culture and intellectual style together with the forces operating within the writer's international disciplinary community interact in the authorial guidance in the scholarly prose.
I introduce and exemplify three types of organising relational structures: Advance Organisers, Introducers and Enumerators. I trace the utilisation of these three types of relations in sociology research papers written in English and produced in "Anglo" and Polish academic discourse comunities by native English speaking and native Polish speaking scholars. The relational typology adopted is based on a study by Golebiowski (2002), which proposed a theoretical framework for the examination of discoursal structure of research papers, referred to as FARS – Framework for the Analysis of the Rhetorical Structure of Texts. FARS entails a relational taxonomy which displays a pattern of rhetorical relations utilised by the writer to achieve textual coherence.
I describe intertextual differences in the frequency of occurrence of organising relations, their degree of explicitness and their positioning in the hierarchical structure of texts. Differences in the mode of employment of textual organisers suggest that the rhetorical structure of English research prose produced by non-native speakers cannot escape being shaped by the characteristics and conventions of the authors’ first language. They are also attributed to cultural norms and conventions as well as educational systems prevailing within the discourse communities which constitute the social contexts of texts.

Refuge in the land of liberty : France and its refugees, from the revolution to the end of asylum, 1787-1939

France has a long tradition of asylum for refugees. Since the Revolution, this has made it the land of liberty (pays de la liberte) and the land of asylum (la terre d'asile)." "In practice, responses have been shaped less by principle than by political and social conditions. Various refugee movements - from the late eighteenth-century Lowlands, to Spanish and Italian liberals in the 1820s, Polish nationalists in the 1830s. German social revolutionaries of 1848-9, anti-Bolsheviks from the Russian Revolution, Christians from the former Ottoman Empire, and Jews from Nazi Germany - have met with mixed responses, which shifted uneasily between sympathy, principle, pragmatism, and open hostility." "This book examines the tensions between refugee rights and political responses to refugees, and between humanitarian concern for their plight and hostility to their imposition on the state. Increasingly punitive measures against refugees saw, in 1939, the end of asylum in the internment of republican exiles from the Spanish Civil War.

Economic transition and commercial property markets : China and Poland

This paper discusses the economic transition and the property market emergence in transition economies. It compares the Chinese property market with the Polish market. It preliminarily examines market emergence and maturity in the context of economic transition, comparing the transitions with the emphasis placed on commercial property markets especially their formation and behaviour. Supply and demand for commercial space in China and Poland are also contrasted. As commercial property market behaviour is somewhat driven by market structure formation process and the business cycle, the transition has provided a “common ground” that enables similarities between the property markets in China and Poland. The challenge for state intervention is mainly due to the agency problem which is also a problem in mature markets; it appears that transitional economies do share common features in their emerging property markets. This paper suggests state intervention in market formation and emergence is necessary and essential. However the actual formation and behaviour of property markets have some distinctive characteristics. Value or implication of the study include: knowing the stage of market emergence is essential for making investment decisions, especially when identifying markets with varying backgrounds. This paper is also relevant to policy-makers in the process of facilitating transitions in emerging markets.

Logic and The Open Society : revising the place of Tarski’s theory of truth within Popper’s political philosophy

This chapter retraces the way in which the Austrian philosopher Sir Karl Popper came to accept a Correspondence Theory of Truth from the work of the Polish logician and mathematician Alfred Tarski. It is argued that Popper’s use of Tarski’s semantic theory of truth reveals crucial insights into the fundamental characteristics of Popper’s social philosophy.  Quite deceptively, arguments based upon Tarski’s theory of truth appear implicitly throughout the text of The Open Society and Its Enemies (1945). It is then demonstrated how Popper integrated a correspondence theory of truth into a theory of the functions of communicative language that he received from Karl Bühler.
