This article reviews selected techniques and current trends in the analysis of contaminants in sediments since the year 2000. Because of the variety of anthropogenic target analytes encountered in sediments, the monograph is separated into inorganic and organic subsections. Practical aspects, including advances in: analysis of standards, biological methods, instrumental methods, modeling aspects, sample preparation and extraction methods, and speciation techniques are discussed. The sediment matrices are complex and require an integrated approach encompassing sampling, preparation, extraction, and analysis steps to reach the detection levels required. Often hyphenated techniques are employed to utilize the multi-resolving and isolation powers of the combined instrumentation. The review mainly focuses on the ability of developing techniques and their approaches and applications not only to solve new problems but also to push detection limits on historically well known inorganic and organic contaminants, while highlighting emerging persistent organic pollutants. The impetus of such research is to obtain a more factual understanding of an ecosystem and overall condition of its habitant in the context of sediments that may act as reservoirs for anthropogenic pollutants. The review is not comprehensive but rather provides an overview of the status of sediment chemical analysis and focuses on the trends in analytical approaches towards analytes of anthropogenic contaminants in sediments.

In 1992, an overview was presented which summarized the status and progress made in the development of very small, “micro” heat pipes, manufactured as stand alone devices or fabricated as an integral part of silicon wafers. Since that initial review, significant advances have been made in the analysis, fabrication and testing of these devices, for use in a wide variety of applications. Following, is a review of the more recent work in this rapidly emerging field. Included is a summary of the analytical techniques developed, the various proposed methods of fabrication, and a summary of the most current test results achieved to date. Because the fundamental operating characteristics of micro heat pipes larger than 1 mm in diameter are similar to that of conventional heat pipes, this review focuses on the analysis, fabrication, and testing of micro heat pipes with characteristic dimensions of less than 500 μm. Particular emphasis is placed on research, related to the development of arrays of micro heat pipes and flat plate micro heat pipes fabricated as an integral part of semiconductor devices.

Structural Aspects

_ The most easterly point of North America was the setting for the 11th International Symposium on Novel Aromatic Compounds (ISNA-11), which took place on 14-18 August 2005 in the picturesque harbor city of St. John's, Newfoundland and Labrador, Canada. An atypically small, but nevertheless enthusiastic, group of 135 delegates representing 17 countries and 64 academic and industrial institutions participated in ISNA-11. The scientific program consisted of 107 posters (two sessions), 26 plenary lectures, and the Nozoe lecture, which was presented by Prof. Koichi Komatsu of Kyoto University.The inaugural ISNA meeting was held in Sendai, Japan in 1970. Since then, ISNA meetings have been held at three- to four-year intervals at locations that cycle between Asia, North America, and Europe. In its infancy, the ISNA community was focused primarily on the definition and quantification of aromaticity, as well as the synthesis and study of compounds that exhibited the phenomenon, whatever it may be. Nourished by advances in synthetic methodology, analytical techniques, separation capabilities, and computational power, ISNA has blossomed over the intervening 35 years to embody a much broader and deeper set of interests. In particular, the twin issues of function and applications have emerged as integral components of ISNA's collective being.The scientific topics of ISNA-11 were selected with an eye toward balancing the traditional areas of interest with its expansion in new directions. The 15 articles that appear in this issue embody these themes, which include:the synthesis of aromatic compoundstheoretically interesting aromatic moleculesstructural aspects of aromaticityaromatic compounds for devicesfullerenes and nanotubesmolecular switches and machinesmacrocyclic aromatic compoundsDebate about the status and future direction of ISNA was actively encouraged, and the overwhelming response was that ISNA is more vibrant and relevant than ever before. It is healthy and growing in many ways. It was therefore decided to move subsequent ISNA meetings to a two-year cycle. This will commence with ISNA-12, which will be held on Awaji Island (located near Kobe) in Japan on 22-27 July 2007. Professor Yoshito Tobe (Osaka University) will serve as conference chair. The responsibility for ISNA-13 was also awarded. It will be organized by Prof. François Diederich (ETH Zürich) and will be held at a yet to be determined European location in 2009.Graham BodwellRik TykwinskiConference Editors

The Welfare State

Political law, political economy and political economy law are three concepts that arise from a deep understanding of the 1945 Constitution as statutory norms. A series that tries to align the interests and desires of the 1945 Constitution with the interests of the state and the people's wishes, which often have different views and practices between the two. This article aims to analyze the direction of Indonesian economic law politics policy in the Welfare State conception based on the 1945 Constitution. The method used is a normative juridical approach with descriptive-analytical techniques using qualitative juridical data analysis methods. This article concludes that the direction of Indonesian economic policy shows some adoption of neoliberalism values that have become references in the formulation of monetary policy in Indonesia. As a government law politics, the direction of economic policy must be oriented towards the institutionalization of the status of the Indonesian nation to advance the general welfare. And the "vehicle" for institutionalizing this staatsidee, as formulated in Article 33 of the 1945 Constitution of the Republic of Indonesia, is the concept of a welfare state.

Linguistic Behaviour

Abstract In recent years, applied linguists have been much concerned with the description of linguistic behaviour previously labelled as «deviant». In particular, a technique known as «error analysis» has been developed by means of which it is claimed access is gained to the «transitional competence» of the L2 learner thus making the description of the learner's «interlanguage» and the explanation of the systematic nature of the errors generated by its grammar possible. Such a Technique can, if its claims are justified, be of inestimable value to linguist, teacher and learner but equally, if its claims are false, can lead to invalid assumptions concerning the nature of the «interlanguage», the form of appropriate teaching materials and learning strategies employed by learners. It is suggested here, that in addition to being based on a number of false assumptions and offering a partly spurious assistance to those engaged in the language learning process, error analysis is in itself, an inadmissable pseudoprocedure which purports to contain a methodology that is, in part, impossible in principle and in part, in practice. Hence, we need to reconsider the status of the concept «interlanguage», the analytical techniques involved in its description and the validity of the claims made for both.

Recent Developments

Molecular diagnosis is based on target detection associated with many diseases and abnormalities. Common analytical techniques have disadvantages in the diagnosis. In contrast, biosensors are performed quick and selective detection of various markers. Surface plasmon resonance (SPR) biosensor allows qualitative and quantitative measurements without labelling and frequently used in medical applications. Recent developments in various emerging disciplines have allowed the design of novel bioreceptors for SPR biosensors. In recent years, the use of bioreceptors combined with nanotechnology and molecular imprinting technologies has increased in SPR instruments. Molecularly imprinted polymers (MIPs) are synthetic polymeric materials and provide specific and selective recognition sites for the target of interest. MIPs as bioreceptor show unique features compared to natural receptors. Therefore, MIP-based bioreceptors in SPR sensors have gained more attention recently. This chapter primarily focuses on the status and applications of nano-MIP-based SPR biosensors for the molecular diagnosis.

<p>Water is a precious resource that is under threat from a number of pressures, including release of toxic compounds that can have damaging effect on ecology and human health. The current methods of water quality monitoring are based on sample collection and analysis at dedicated laboratories. This can provide an incomplete picture of the status of the water body as pollution events can be missed. Recently, electrochemical based methods have attracted a lot of attention for environmental sensing owing to their versatility, sensitivity and compatible integration with cost effective, smart and portable readout systems. In the present work, we report on the fabrication and characterization of platinum interdigitated microband electrodes arrays, and their application for trace detection of copper. Using square wave voltammetry after acidification with mineral acids, a limit of detection of 0.8 μg/L was achieved. Copper detection was also under taken on river water samples and compared with standard analytical techniques. The possibility of controlling the pH at the surface of the sensors – thereby avoiding the necessity to add mineral acids – was investigated. By applying potentials driving the water splitting reaction at one comb on the sensors electrode (the protonator), it was possible to lower the pH in the vicinity of the sensing electrode. Detection of standard copper solutions down to 5 μg/L using this technique is reported. This reagent free method of detection opens the way for autonomous, in situ monitoring of pollutants in water bodies.</p>
