ABSTRACTIs there any need for further scientific and technical development work in the field of waste management? Radically different views on this provocative question have been put forward by opposing sides in the nuclear debate. P. Slovik [1] quotes various leaders on the nuclear community who for years have been claiming that waste management has no unsolved technical problems. At the recent public hearing in England [2], on the other hand, Greenpeace and others convinced the Inspector that, despite a GBP 200 million site characterisation programme with many deep boreholes, UK-Nirex still knew too little about the deep hydrogeology to justify even the sinking of an exploratory shaft at Sellafield. Where does the truth lie?

Contemporary Topic

The article examines the concept and metaphorical meaning of waste and dirt in short folklore forms, including archival material (phrasemes, proverbs, and beliefs) and also internet memes as a new, contemporary folklore form. Waste and dirt are traditionally conceptually linked to metaphors of unwanted, used, lower-quality, or even immoral. Slovenian proverbs and phrasemes, on the other hand, do not thematize waste management or handling dirt; only beliefs show some part of this. New forms, on the other hand, emphasize environmental pollution directly, using concepts of waste and pollution combined in words and images intended to persuade the viewer or recipient to change their behavior into environmentally responsible behavior. Waste and dirt reveal themselves as important metaphorical elements, as well as a contemporary topic for new folklore genres.

Canada and Sweden are two countries that are actively involved in environmental protection and both go as far as to declare themselves among the most environmentally friendly countries in the world. However, a report issued by the Organization for Economic Cooperation and Development (OECD) ranked each participating country in twenty five key environmental factors and saw Canada place 28th overall out of the 29 participating countries. Sweden on the other hand saw itself coming in at a respectable 10th (Boyd, 2001). The similarities between the two countries in terms of Human Development Index (HDI), Gross Domestic Product (GDP), general climate and interest in environmental protection would at first impression imply similar standards of living and therefore waste production. However, the numbers clearly demonstrate the Sweden is well ahead of Canada in terms of generating and managing its waste.The purpose of this study is to conduct a comparison of waste generation and composition between the two countries on a national scale as well as on a municipal one. Determining the differences between Canadians and Swedes from a waste generation perspective will highlight the cultural differences that create this phenomenon. On the other hand, the analysis of several different municipalities in each country will demonstrate the effects that policies can have on the way waste is managed and ultimately, how it will affect the environment. These analyses will help determine whether or not Canada can imitate Sweden and make its current waste management Canada can imitate Sweden and make its current waste management systems more efficient.

Hydrological Variables

Regional frequency analysis (AFR) brings together a variety of statistical methods aimed at predicting the behavior of extreme hydrological variables at ungauged sites. Regression techniques, geostatistical methods and classification are among the statistical tools frequently encountered in the literature. Methodologies based on these tools lead to regional models that offer a simple, but very useful description of the relationship between extreme hydrological variables and physiometeorological characteristics of a site. These regional models then make it possible to predict the behavior of variables of interest at places where no hydrological information is available. These methods are generally based on restrictive theoretical assumptions, including linearity and normality. These do not reflect the reality of natural phenomena. The general objectives of this paper are to identify the methods affected by these hypotheses, evaluate their impacts and propose improvements aimed at obtaining more realistic and fairer representations. Projection pursuit regression is a non-parametric method similar to generalized additive models and artificial neural networks that are considered in AFR to take into account the non-linearity of hydrological processes. In a comparative study, this paper shows that regression with revealing directions makes it possible to obtain more parsimonious models while preserving the same predictive power as the other nonparametric methods. Canonical Correlation Analysis (ACC) is used to create neighborhoods within which a model (e.g. multiple regression) is used to predict hydrologic variables at ungagged sites on the other hand, ACC strongly depends on the assumptions of normality and linearity. A new methodology for delineating neighborhoods is proposed in this paper and uses revealing direction regression to predict a reference point representing hydrological and physiometeorological information that is relevant to these groupings. The results show that the new methodology generalizes that of ACC, improves the homogeneity of neighborhoods and leads to better performance. In AFR, kriging techniques on transformed spaces are suggested in order to predict extreme hydrological variables. However, a transformation is required so that the hydrological variables of interest derive approximately from a multidimensional normal distribution. This transformation introduces a bias and leads to suboptimal predictions. Solutions have been proposed, but have not been tested in AFR. This paper proposes the approach of spatial copulas and shows that this approach provides satisfactory solutions to the problems encountered with kriging techniques. Max-stable processes are a theoretical formalization of spatial extremes and correspond to a more faithful representation of hydrological processes on the other hand; their characterization of extreme dependence poses technical problems which slow down their adoption. In this paper, the approximate Bayesian calculus is examined as a solution. The results of a simulation study show that the approximate Bayesian computation is superior to the standard approach of compound likelihood. In addition, this approach is more appropriate in order to take into account specification errors.

The article is focused on the presentation and analysis of two historical deter- minants that probably had the greatest impact on the rise and development of global mobile phone markets. On the one hand, this is the technical development of wireless telephony, which can also be seen as a space that provided a major impulse for political and legał changes in telecommunications. On the other hand, these political and legał changes associated with processes of liberalization in the world telecommunications have been described as the second fundamental factor.

Can the Constitution be healed? The aim of this article is the answer on how to deal with offenses committed in the face of the Constitution which are built on consolidated factual situations. Often the simple declaration of unconstitutionality, either from the beginning, the theory of nullity, or for the future, in annulability theory, or in conjunction both with the temporal modulation effects will not show positive responses to the constitutional offense. On the other hand, the recognition of unconstitutionality, although for the future, could lead to more harmful economic, political, social and legal effects than maintaining the offensive act. Sometimes the theory of constitutionalising supervening can respond appropriately, with the change of the constitutional paradigm. But what to do when the Constitution is even changed? The methodology for the development work is eminently literature and case law.

Sterilization Process

Mushroom farmer society Sedyo Lestari is located in the Argosari, Sedayu, Bantul. The high demand for mushrooms media (baglog) is a good business opportunities for this farmer society. But the process of baglog making requires a lot of energy in the form of firewood, especially for sterilization process of the baglog. On the other hand, the mushroom cultivation process itself remains the waste that can be used as fuel for the sterilization process. So far Sedyo Lestari farmer society members do not have the technology to used the mushroom cultivation waste as a fuel. Therefore, it is imperative to transfer knowledge of biomass briquetting technique. The method used in this activities are socialization, training, and mentoring by starting with the introduction of briquettes and briquetting technology. Subsequently made briquette-making machines followed by training briquette making. Mentoring and socialization were also made to all members of farmer society. Outcome of these activities was briquette-making machines that can be used by all members of the society as well as knowledge about the process of making briquettes. The benefit of using briquettes of mushroom cultivation media waste as fuel for subtitute the firewood can provide savings to the expenditures of farmers for buying firewood and solving the waste management problems for farmers.

I reflect on two aesthetics which are at play in the presentation of critical disability and development work in the global south. On the one hand, authors of critical texts commonly use very complex and abstruse language, which may make such texts relatively inaccessible to some disabled people in the global south. On the other hand, the ways in which development work in the south is portrayed sometimes emphasises methods of engagement which may seen to be infantilising. Drawing on my own experience in such engagement activities, I suggest that it is important to understand, and to subvert, dominant forms of representation.

Sudden Rise

AbstractWe have developed a model for theH2OandOHevolution in a comet outburst, assuming that together with the gas, a distribution of icy grains is ejected. With an initial mass of icy grains of 108kg released, theH2OandOHproductions are increased up to a factor two, and the growth curves change drastically in the first two days. The model is applied to eruptions detected in theOHradio monitorings and fits well with the slow variations in the flux. On the other hand, several events of short duration appear, consisting of a sudden rise ofOHflux, followed by a sudden decay on the second day. These apparent short bursts are frequently found as precursors of a more durable eruption. We suggest that both of them are part of a unique eruption, and that the sudden decay is due to collisions that de-excite theOHmaser, when it reaches the Cometopause region located at 1.35 × 105kmfrom the nucleus.

Transmission Microscope

We have become accustomed to differentiating between the scanning microscope and the conventional transmission microscope according to the resolving power which the two instruments offer. The conventional microscope is capable of a point resolution of a few angstroms and line resolutions of periodic objects of about 1Å. On the other hand, the scanning microscope, in its normal form, is not ordinarily capable of a point resolution better than 100Å. Upon examining reasons for the 100Å limitation, it becomes clear that this is based more on tradition than reason, and in particular, it is a condition imposed upon the microscope by adherence to thermal sources of electrons.

Life beyond 1MeV – like life after 40 – is not too different unless one takes advantage of past experience and is receptive to new opportunities. At first glance, the returns on performing electron microscopy at voltages greater than 1MeV diminish rather rapidly as the curves which describe the well-known advantages of HVEM often tend towards saturation. However, in a country with a significant HVEM capability, a good case can be made for investing in instruments with a range of maximum accelerating voltages. In this regard, the 1.5MeV KRATOS HVEM being installed in Berkeley will complement the other 650KeV, 1MeV, and 1.2MeV instruments currently operating in the U.S. One other consideration suggests that 1.5MeV is an optimum voltage machine – Its additional advantages may be purchased for not much more than a 1MeV instrument. On the other hand, the 3MeV HVEM's which seem to be operated at 2MeV maximum, are much more expensive.
