Regulatory History Material as an Extrinsic Aid to Interpretation: An Empirical Study on the Use of RIAS by the Federal Court of Canada

Since 1986, the Canadian Public Administration is required to analyze the socio-economic impact of new regulatory requirements or regulatory changes. To report on its analysis, a Regulatory Impact Analysis Statement (RIAS) is produced and published in the Canada Gazette with the proposed regulation to which it pertains for notice to, and comments by, interested parties. After the allocated time for comments has elapsed, the regulation is adopted with a final version of the RIAS. Both documents are again published in the Canada Gazette. As a result, the RIAS acquires the status of an official public document of the Government of Canada and its content can be argued in courts as an extrinsic aid to the interpretation of a regulation. In this paper, an analysis of empirical findings on the uses of this interpretative tool by the Federal Court of Canada is made. A sample of decisions classified as unorthodox show that judges are making determinations on the basis of two distinct sets of arguments built from the information found in a RIAS and which the author calls “technocratic” and “democratic”. The author argues that these uses raise the general question of “What makes law possible in our contemporary legal systems”? for they underline enduring legal problems pertaining to the knowledge and the acceptance of the law by the governed. She concludes that this new interpretive trend of making technocratic and democratic uses of a RIAS in case law should be monitored closely as it may signal a greater change than foreseen, and perhaps an unwanted one, regarding the relationship between the government and the judiciary.

"Mémoire Présenté à la Faculté des Études Supérieures en vue de l'obtention du Grade de Maîtrise En Droit Option Recherche"

Under the roof and the pen of Elizabeth Willing Powel. Material culture, sociability, and letters in revolutionary and early republican Philadelphia

Ce mémoire a pour toile de fond Philadelphia à la fin du dix-huitième siècle et couvre les périodes de la Révolution américaine et les débuts de la République. Trois thèmes s’y entrelacent: la culture matérielle, la sociabilité, et l’agentivité des femmes. Ces trois thèmes sont explorés au travers de Elizabeth Willing Powel, une femme éduquée faisant partie de l’élite de Philadelphie, et des moyens avec lesquels elle s’auto-projetait auprès de la société au travers l’environnement matériel de sa maison – la Powel House – and au travers de sa correspondance. Elizabeth Powel était reconnue pour son intelligence, son art de la conversation et ses qualités d’hôtesse. Ce projet explore les interactions entre une femme de l’élite et son environnement matériel durant les périodes révolutionnaires et postrévolutionnaires. Le but est d’observer comment la culture matérielle représentait des positions sociales, culturelles et politiques. Ce mémoire observe les interactions sociales et les façons dont Elizabeth Powel se représente en société par une analyse de sa correspondance, analyse qui porte une attention particulière aux discours de Elizabeth sur les questions du rôle des femmes en société, de l’éducation des femmes. Enfin, ce mémoire explore comment la culture matérielle et l’écriture épistolaire étaient des vecteurs d’agentivité pour Elizabeth, des moyens de participer aux important changements qui transformaient la société américaine de la fin du dix-huitième siècle.

Recycling of NR Based Cured Latex Material Reclaimed with 2,2'-Dibenzamidodiphenyldisulphide in a TruckTire Tread Compound

It is observed that reclamation of natural rubber latex based rubber using 2,2'-dibenzamidodiphenvldisulphide as reclaiming agent is an optional methodology for recycling of waste latex rubber (WLR). For progressive replacement of virgin natural rubber by the reclaim, two alternatives curing system were investigated: adjustment or reduction of the curing system with increasing reclaim content, to compensate for the extra amount of curatives brought along by the reclaim. For fixed curing system, as if the reclaim were equivalent to virgin NR. The cure behavior, final crosslink density and distribution, mechanical properties, and dynamic viscoelastic properties of the blends with reclaimed WLR are measured and compared with the virgin compound. The morphology of the blends, sulfur migration, and final distribution are analyzed.The mechanical and dynamic viscoelastic properties deteriorate for both curing systems, but to a lesser extent for fixed curing system compared to adjusted curing system. With the fixed cure system, many properties like tensile strength and compression set do still deteriorate, but tan 6 and Mrrr„/Murxr, representative for the rolling resistance of tires are improved. On the other hand, with the adjusted cure system both mechanical and dynamic properties still deteriorate.

A molecular level study has been conducted to analyze the adhesion mechanism of protein adhesion molecules on to HA coated implants.

Development of Free Space Method for Material Characterisation and GPR Study & A Case Study on Biological Samples

The thesis mainly focuses on material characterization in different environments: freely available samples taken in planar fonn, biological samples available in small quantities and buried objects.Free space method, finds many applications in the fields of industry, medicine and communication. As it is a non-contact method, it can be employed for monitoring the electrical properties of materials moving through a conveyor belt in real time. Also, measurement on such systems at high temperature is possible. NID theory can be applied to the characterization of thin films. Dielectric properties of thin films deposited on any dielectric substrate can be determined. ln chemical industry, the stages of a chemical reaction can be monitored online. Online monitoring will be more efficient as it saves time and avoids risk of sample collection.Dielectric contrast is one of the main factors, which decides the detectability of a system. lt could be noted that the two dielectric objects of same dielectric constant 3.2 (s, of plastic mine) placed in a medium of dielectric constant 2.56 (er of sand) could even be detected employing the time domain analysis of the reflected signal. This type of detection finds strategic importance as it provides solution to the problem of clearance of non-metallic mines. The demining of these mines using the conventional techniques had been proved futile. The studies on the detection of voids and leakage in pipes find many applications.The determined electrical properties of tissues can be used for numerical modeling of cells, microwave imaging, SAR test etc. All these techniques need the accurate determination of dielectric constant. ln the modem world, the use of cellular and other wireless communication systems is booming up. At the same time people are concemed about the hazardous effects of microwaves on living cells. The effect is usually studied on human phantom models. The construction of the models requires the knowledge of the dielectric parameters of the various body tissues. lt is in this context that the present study gains significance. The case study on biological samples shows that the properties of normal and infected body tissues are different. Even though the change in the dielectric properties of infected samples from that of normal one may not be a clear evidence of an ailment, it is an indication of some disorder.ln medical field, the free space method may be adapted for imaging the biological samples. This method can also be used in wireless technology. Evaluation of electrical properties and attenuation of obstacles in the path of RF waves can be done using free waves. An intelligent system for controlling the power output or frequency depending on the feed back values of the attenuation may be developed.The simulation employed in GPR can be extended for the exploration of the effects due to the factors such as the different proportion of water content in the soil, the level and roughness of the soil etc on the reflected signal. This may find applications in geological explorations. ln the detection of mines, a state-of-the art technique for scanning and imaging an active mine field can be developed using GPR. The probing antenna can be attached to a robotic arm capable of three degrees of rotation and the whole detecting system can be housed in a military vehicle. In industry, a system based on the GPR principle can be developed for monitoring liquid or gas through a pipe, as pipe with and without the sample gives different reflection responses. lt may also be implemented for the online monitoring of different stages of extraction and purification of crude petroleum in a plant.Since biological samples show fluctuation in the dielectric nature with time and other physiological conditions, more investigation in this direction should be done. The infected cells at various stages of advancement and the normal cells should be analysed. The results from these comparative studies can be utilized for the detection of the onset of such diseases. Studying the properties of infected tissues at different stages, the threshold of detectability of infected cells can be determined.

Prospects of sprayed CZTS thin film solar cells from the perspective of material characterization and device performance

This thesis is devoted to the development of a relatively new, rapidly developing quaternary semiconducting material (viz., Cu2ZnSnS4) used for photovoltaic applications. This semiconductor, commonly known as CZTS, is closely related to a family of materials that have been used for solar cell applications. It is a compound semiconductor made of copper, zinc, tin and sulfur, which are sufficiently abundant elements; none of them is harmful to the environment even at large scale usage. Aim of this study is to fabricate CZTS solar cells through chemical spray pyrolysis (CSP) technique. At first the influence of various spray parameters like substrate temperature, spray rate, precursor ratio etc. on the opto-electronic properties of CZTS films will be studied in detail. Then the fabrication of CZTS/In2S3 hetero junctions and various ways to improve the performance parameters will be tried

Effect Of Raw Material Quality On The Shelf Life Of Frozen Stored Fish And Fishery Products

Frozen storage characteristics and shelflife vary considerably among species as well as within the species (Powrie, 1973; Fennema. 1973). This can be attributed to the variation in the composition of fish among various species. In certain species like sardines and mackerel. wide seasonal variation in chemical composition occur within the species. These variations affect the quality and shelflife. The nutritional level of water. spawning, method of catching, struggling etc. are found to have profound influence on the condition of the fresh fish. Soon after death the deteriorative changes in fish start due to autolysis and bacterial growth. The rate of these changes depends mainly on temperature. The handling methods have great influence on bacterial contamination. Thus the type oi'handling. temperature control. period of chill storage. processing methods. type of freezing, condition of frozen storage and period of storage affect the quality and shelflife Of the fisho In the present study extensive investigations were carried out on various factors affecting the quality of fish as well as their effect on the physical. chemical and sensory qualities of fish during frozen storage and the shelflife
