Hong, Seung-Hee. "The necessity of transition to no fault divorce and legal reform measures: Based on a comparative legal review". Korean Society Of Family Law 37, n.º 3 (30 de novembro de 2023): 259–333. http://dx.doi.org/10.31998/ksfl.2023.37.3.259.

In Korea, the Japanese Civil Code was used during the Japanese colonial period, and the Civil Code, a translation of the Japanese Civil Code, was applied until the Korean Civil Code enacted in 1958 was enforced in 1960. The Korean Civil Code is very similar to the Japanese civil law, and the number of articles is significantly smaller and lacks specificity compared to the civil laws of many Western countries. In the case of the divorce law, the deficiencies of such legislation are being supplemented by the interpretation of the courts. Divorce laws in the West, such as Germany, England, France, and the United States, have been revised in the direction of protecting the rights and interests of the parties through numerous historical changes and discussions since the 19th century. Based on the history of changes in various Western countries, Korea will also need to revise the civil law in the direction of fulfilling the state's constitutional duty to protect marriage and family life.
Through counseling before marriage and divorce, the marriage and family system should be strengthened, and counseling and other educational programs should be activated so that a recoverable family can be saved. In order to minimize conflicts in a marriage relationship that has already been irretrievably broken and exists only legally, no fault divorce based on separation for a certain period of time should be introduced. And in order to protect innocent spouses and children who do not want to divorce, marriage should be terminated only if protective measures or agreements for innocent spouses and children are included in the divorce ruling, and divorce should not be allowed if the divorce threatens to cause economic, social and psychological difficulties for them.
In addition, if legal separation system where the obligation to cohabit is exempted and a marriage is deemed to have broken down after a certain period of separation is established, I think it can serve as a buffer zone to encourage reunion after separation and also as a gateway from marriage to divorce. The legal separation system can alleviate the impact of divorce, and has an economic effect almost similar to divorce, except that the marriage relationship is legally maintained, so the parties can attempt reconciliation while stably separating for a certain period of time.
I think it is desirable to unify the divorce procedure by incorporating the divorce by agreement system into the judicial divorce procedure to ensure that the rights and interests of the divorced parties are fully protected. As with the divorce laws of many countries that adopt no fault divorce, even if there is mutual consent to divorce, divorce must be conducted through a trial and should be granted only after court approval of an agreement regarding children and the financial effects of the divorce. Additionally, if a couple with minor children wants to divorce by agreement, counseling should be mandatory.
In addition, according to the Supreme Court precedent, Korea's property division system has the main purpose of distributing the actual common property acquired during marriage, and the supportive nature such as consideration for the other person's livelihood security is added. Since the current support system is insufficient to protect spouses with poor economic status in that the system is not provided by law, a separate support system after divorce should be prepared like in many Western countries.
As pointed out by the Supreme Court's ruling in 2015, the fact that the spouse responsible for breakdown of marriage is not allowed to file for divorce is also intended to prevent the other spouse from being expelled by the spouse in the bigamous relationship.

Texto completo da fonteResumo:
The article examines the possibility of introducing European approaches in the process of updating the institution of separate residence of spouses. The experience of European states regarding the regulation of the institution of separation (France, Portugal, Belgium, the Netherlands, Poland, etc.) is clarified in a comparative aspect. Three main approaches to the regulation of the legal regime of separate residence of spouses in foreign countries are singled out: an approach in which the independence of the institution of separation and termination of marriage is preserved; an approach in which the grounds for separation and divorce are the same, so the spouses can choose one of the specified two models; an approach in which dissolution of marriage depends on separation, which must precede termination of marriage. Two approaches in the world regarding the contractual method of establishing a regime of separate residence have been clarified, in particular. The common and distinctive features between separation and the actual termination of marital relations, as well as divorce, have been clarified. The judicial practice in cases of establishing the actual termination of marital relations, separation, as well as the termination of the regime of separate residence of spouses has been analyzed. The position of the Supreme Court regarding consideration of counterclaims for establishment of separation is noted. The need to settle the issue of the place of residence of spouses and children when the regime of separate residence of spouses is established, and the issue of child support, has been clarified. It is substantiated that in the process of Europeanization of the provisions of the Civil Code of Ukraine, it is necessary to provide norms that would provide that during the establishment of the regime of separate residence of the spouses, the rights of children are properly protected and the best interests of the child are taken into account. Other issues related to the rights and responsibilities of husband and wife as spouses can be settled by agreement if they wish. Corresponding changes to the Civil Code of Ukraine have been proposed to provide for a contractual procedure for establishing separation and proper protection of the best interests of the child.

Texto completo da fonteResumo:
The article explores the genesis of the legislative consolidation of copyright law in the Ukrainian lands that were a part of the Russian Empire. The thesis is substantiated that the legal regulation of copyright law in these territories was formed under the influence of both European legal traditions and imperial legislative norms. It was revealed that the formation of the idea of authorship in Russia occurred much later than in European countries. The reasons were the long-term attachment of copyright law to censorship legislation and the late commercialization of publishing. It was revealed that the right to literary property was first established in Russian legislation. The literary property was considered as acquired property. Later on, the right of musical and artistic property received legal protection. The thesis has proved that the proprietary concept of copyright law in Russia has been dominant for a long time. At the end of the 19th century, the question of the legal nature of copyright law became relevant, which ultimately formed the idea of separating property and non-property interests of the author in Russian law. Therefore, the evolution of copyright law in the Russian Empire is characterized by a transition from the protection of the interest of the distributor of the work to the protection of the interest of the author.
It was revealed that in the 19th century Russia was in certain isolation and did not participate in the most important international agreements on the protection of intellectual property, except for two bilateral conventions with France and Belgium on the protection of copyright law. It was established that the copyright law in 1911 brought the legal regulation of copyright law in the Russian Empire to the European level and introduced many progressive novellas that positively impacted the further development of the institution of copyright law.
All-Russian legislation of copyright law was also extended to Ukrainian-controlled lands. However, it is indicated that Russia introduced rather strict censorship rules for Ukrainian-language publications to their complete ban, therefore there is no need to talk about the protection of copyrights law of Ukrainian authors.

Texto completo da fonteResumo:
In the jubilee year 2004, Serbia marks the 200th anniversary of The First Serbian Uprising, structuring of modern Serbian state and its legal system comparatively speaking, France marks the 200th anniversary of passing the French Civil Code, one of the most significant civil codifications in the 19th century. It was an occasion to study certain institutions of family law through history and today. The used approach is modern, we studied the ways how the principle of self-determination influenced the family-legal solutions today, and we investigated if one could talk about the effect of this principle in the historical sense, too. The principle of self-determination implies the possibility for the subjects of family-legal relations to arrange their own relations themselves ? both the partner and parent relations. However, this principle undergoes significant limitations in the family law because the family relations are personal relations by character, as well as because of the need to protect the weaker participant, both the weaker partner or a child who needs protection stemming from his/her very status. Within marriage law, the principle of self-determination of the spouses (extramarital partners) is, among other things, made concrete through the possibility for an agreement about the effects of marriage (extramarital union), then through the possibility of agreed divorce, while the procedure of mediation in the marriage litigation contributes to the realization of the mentioned principle. As for the effects of marriage (extramarital union), the paper particularly discusses property relations, that is the marriage property contract, because it is at the moment a current issue in our domestic law. Within the relations between parents and children, the concretization of the principle of self-determination in parental care is significant, particularly in the situations when the relations between the parents were disturbed and resulted in a separation or a divorce with the joint parental care (application of the parental right). All institutions are analyzed in the positive law, in the historical context (solutions from the Serbian Civil Code the former Hungarian Law), and viewed comparatively in the European legal systems of the east and west European countries.

Texto completo da fonteResumo:
Bien des couples, aujourd’hui, passent du concubinage au pacs, puis du pacs au mariage, qui sont les trois conjugalités que propose le droit contemporain. À chacune correspond un statut patrimonial spécifique (prévoyant une répartition des biens et des dettes, instituant des effets sociaux et fiscaux, etc.). Or ces statuts sont en pleine mutation : aujourd’hui, on ne compte plus les transformations légales et jurisprudentielles qui s’accomplissent. Quelles sont ces évolutions ? Jusqu’où doivent-elles se poursuivre ? Tel est l’objet de cette étude. Elle relativise l’idée qu’un droit commun du couple serait appelé à émerger : elle constate que, même si un phénomène de convergence est à l’œuvre, d’autres évolutions tendent à accroître certaines différences entre les conjugalités. Elle démontre alors que le droit positif se structure sur le modèle d’une gradation. Plus un couple choisit une conjugalité stable et engagée, plus son statut patrimonial devient exorbitant, communautaire et protecteur. Les amants sont ainsi incités à s’engager sur un chemin jalonné d’étapes prédéterminées (couple sentimental, emménagement, pacs, mariage) que l’on peut appeler iter copulae ; ce modèle est en phase non seulement avec le droit positif, mais aussi avec la réalité sociologique moderne.Ainsi, l’étude synthétise les évolutions en cours. Elle suggère de les approfondir où elles sont inachevées, de les tempérer où elles sont excessives, de les consacrer où elles sont prétoriennes ; le propos est parsemé de propositions de réformes, toutes destinées à asseoir le droit positif sur des bases durables, car plus en phase avec les aspirations modernesMany French couples today move from cohabitation to civil partnership, then from civil partnership to marriage, which are the three forms of conjugality offered by contemporary law. Each has its own specific property status (providing for the division of assets and debts, establishing social and tax effects, etc.). But these statuses are in a state of flux,with countless legal and case law changes being made. What are these changes ? How far should they continue ? That is the purpose of this study. It sets itself apart by putting into perspective the idea that a common law governing couples will emerge : it notes that, even if a phenomenon of convergence is at work, other developments are tending to increase certain differences between conjugal relationships. It then shows that positive law is structured on the model of a gradation. The more a couple chooses a stable and committed conjugal relationship, the more their property status becomes exorbitant, communal and protective. Lovers are thus encouraged to embark on a path marked out by predetermined stages (romantic relationship, moving in, civil partnership, marriage) that can be called iter copulae ; thismodel is in line not only with positive law, but also with modern sociological reality. The study summarises current developments. It suggests deepening them where they are incomplete, tempering them where they are excessive, and enshrining them where they are praetorian. The study is interspersed with proposals for reform, all designed to put positive law on a sustainable footing, since it is more in tune with modern aspirations

The effect of soft segment, isocyanate and chain extender chemical structure on the physical and mechanical properties of thermoplastic polyurethane elastomers was systematically investigated. Several series of materials were produced with identical stoichiometry and under the same reaction conditions. The raw materials used to synthesise these materials were systematically altered to facilitate comment on the influence of molecular weight, cohesive energy density (CED) and molecular geometry on the phase separation phenomena observed in polyurethane elastomers.

Texto completo da fonteResumo:
This study examined several features of flexible polyurethane foams from a structure-property perspective. A major part of this dissertation addresses the issue of connectivity of the urea phase and its influence on mechanical and viscoelastic properties of flexible polyurethane foams and their plaque counterparts. Lithium salts (LiCl and LiBr) were used as additives to systematically alter the phase separation behavior, and hence the connectivity of the urea phase at different scale lengths. Macro connectivity, or the association of the large scale urea rich aggregates typically observed in flexible polyurethane foams was assessed using SAXS, TEM, and AFM. These techniques showed that including a lithium salt in the foam formulation suppressed the formation of the urea aggregates and thus led to a loss in the macro level connectivity of the urea phase. WAXS and FTIR were used to demonstrate that addition of LiCl or LiBr systematically disrupted the local ordering of the hard segments within the microdomains, i.e., it led to a reduction of micro level connectivity or the regularity in segmental packing of the urea phase. Based on these observations, the interaction of the lithium salt was thought to predominantly occur with the urea hard segments, and this hypothesis was confirmed using quantum mechanical calculations. Another feature of this research investigated model trisegmented polyurethanes based on monofunctional polyols, or "monols", with water-extended toluene diisocyanate (TDI) based hard segments. The formulations of the monol materials were maintained similar to those of flexible polyurethane foams with the exceptions that the conventional polyol was substituted by an oligomeric monofunctional polyether of ca. 1000 g/mol molecular weight. Plaques formed from these model systems were shown to be solid materials even at their relatively low molecular weights of 3000 g/mol and less. AFM phase images, for the first time, revealed the ability of the hard segments to self-assemble and form lath-like percolated structures, resulting in solid plaques, even though the overall volume of the system was known to be dominated by the two terminal liquid-like polyether segments. In another aspect of this research, foams were investigated in which the ratios of the 2,4 and 2,6 TDI isomers were varied. The three commercially available TDI mixtures, i.e., 65:35 2,4/2,6 TDI, 80:20 2,4/2,6 TDI, and 100:0 2,4/2,6 TDI were used. These foams were shown to display marked differences in their cellular structure (SEM), urea aggregation behavior (TEM), and in the hydrogen bonding characteristics of the hard segments (FTIR). Finally, the nanoscale morphology of a series of 'model' segmented polyurethane elastomers, based on 1,4-butanediol extended piperazine based hard segments and poly(tetramethylene oxide) soft segments, was also investigated using AFM. The monodisperse hard segments of these 'model' polyurethanes contained precisely either one, two, three, or four repeating units. Not only did AFM image the microphase separated morphology of these polyurethanes, but it also revealed that the hard domains preferentially oriented with their long axis along the radial direction of the spherulites which they formed.Ph.

Wang, Chenyu Jr. "Synthesis of crosslinked polyurethane and Network constrained surface phase separation". VCU Scholars Compass, 2011. http://scholarscompass.vcu.edu/etd/2630.
Texto completo da fonteResumo:
To create functional surfaces for soft materials, such as polyurethanes, our approach is to use a semifluorinated surface modifier as minor component to the matrix material. The surface modifier, driving by reduction in surface energy, surface-concentrates to form a functionalized surface layer at the air-polymer interface. In our previous studies, linear PTMO-based polyurethanes were used as the matrix material. These systems undergo slow surface phase separation at room temperature due to the thermodynamically immiscibility of the soft blocks. In this study, chemically crosslinked matrix was developed to provides a steric hindrance to constrain the mobility of surface modifier and to form a kinetically stable surface. The physical property and morphology of base crosslinked matrix has been characterized using DSC, UTT, DMA and AFM. The surface morphology of surface modified crosslinked matrix has been characterized using AFM, DCA and XPS.

Texto completo da fonteResumo:
Phenylindane monomers 5(6)-amino-1-(4-aminophenyl)-1,3,3-trimethylindane (DAPI), 5,6-diamino-1-(4-aminophenyl)-1,3,3-trimethylindane (TAPI) and 6-hydroxy-
1-(4-hydroxyphenyl)-1,3,3-trimethylindane (DHPI) were synthesized and characterized. DAPI, as well as other diamines, were then utilized in solution step polycondensation with a number of commercially available dianhydrides using either the two-step ester-acid solution imidization or the high temperature solution imidization routes. High molecular weight soluble fully cyclized polyimides were successfully synthesized using a 1:1 molar ratio of dianhydride to diamine. The polyimides were film forming and were characterized by size exclusion chromatography (SEC), differential scanning calorimetry (DSC), thermogravimetric analysis (TGA) and selective gas permeation methods, as well as other techniques. The O2 permeation and O2/N2 selectivity values obtained for materials prepared in this thesis are discussed in relation to the concept of an "upper bound", as defined in the literature concerning gas separation membranes.
The series of polyimides based on DAPI and several dianhydrides were found to have high glass transition temperatures (247°C-368°C) and very good short-term thermal stability as shown by TGA, despite the partially aliphatic character of DAPI. The 5,5'-[2,2,2-trifluoro-1-(trifluoromethyl)ethylidene]bis-1,3-isobenzenefurandione (6FDA)/DAPI system also exhibited low weight loss under nitrogen at 400°C, which was comparable to that of a wholly aromatic polyimide based on 1,2,4,5-benzenetetracarboxylic dianhydride (PMDA)/4,4'-oxydianiline (ODA) which is known to have high thermal stability. In addition, the 6FDA/DAPI polyimides had a refractive index value of 1.571 from which the dielectric constant was calculated, giving an attractively low estimated value of 2.47.
The rigid, bulky and isomeric structure of DAPI in the repeat unit imparted film forming characteristics that allowed production of solvent cast membranes which displayed a range of O2 permeability and O2/N2 selectivity characteristics. High O2 permeabilities were observed for polyimides in which the DAPI structure predominated in relation to the overall polymer repeat unit, i.e. in combination with low molar mass dianhydrides. The more flexible dianhydrides afforded a greater degree of molecular freedom and were thought to result in a more tightly packed polymer conformation which decreased the rate of gas penetration through thin films. The DAPI/3,3',4,4'-benzophenonetetracarboxylic dianhydride (BTDA) system showed the best combination of O2 permeability and O2/N2 selectivity values (2.8Ba and 7.3, respectively). Modest variations in the DAPI isomeric ratio did not significantly effect the gas permselectivity properties.
High molecular weight polyimides based on DAPI and BTDA were synthesized by three different routes. The ester-acid and thermal imidization methods produced polyimides with the highest Tgs and best thermal stability in air, as compared to the chemical imidization procedure. For example, a Tg increase of 22°C and a 68°C increase in the 5% weight loss were found for the ester-acid imidized DAPI/BTDA polyimide over those found for the chemically imidized version. The higher Tg and 5% weight loss values were attributed to the elimination of residual uncyclized amide acid moieties.
Polyimides derived from 6FDA were synthesized by the high temperature solution imidization method. Thin films, cast from NMP, were tough and creasable and afforded high Tg (>295°C) systems with good thermal stability. When combined with rigid diamines, 6FDA contributed to high O2 permeation and moderate O2/N2 selectivity. The high O2 permeability was ascribed to hindered interchain packing attributed to the bulky CF3 groups. The exceptionally high oxygen permeability and O2/N2 selectivity values of the 9,9-bis(4-aminophenyl) fluorene (FDA)/6FDA system, were near the desirable "upper bound" for gas separation membrane materials, while those of 3,7-diamino-2,8-dimethyl-dibenzothiophene-5,5-dioxide (DDBT)/6FDA were actually above the upper bound.
High performance polymers based on 4,4'-bis [4-(3,4-dicarboxyphenoxy)]biphenyl dianhydride (BPEDA), 2,2'-bis [4-(3,4-dicarboxyphenoxy)phenyl] propane dianhydride (BPADA), 2,2-bis(3-amino-4-methylphenyl)hexafluoroisopropylidene dianhydride (Bis-AT-AF) and 3,7-diamino-2,8-dimethyl-dibenxothiophene-5,5-dioxide (DDBT) were also synthesized in this work. Additionally, they were characterized with regard to molecular weight, glass transition temperature, and thermal stability.
Polyimide systems containing hydroxyl moieties in the repeat unit were also investigated. Incorporation of hydroxyl moieties in the repeat unit enhanced chain stiffness via intermolecular hydrogen bonding and showed Tg increases of ~30°C Hydroxyl moieties also decreased the thermal stability values typically observed for polyimides. High O2/N2 selectivity was achieved with all of the 4,4'-diaminobiphenyl-3,3'-diol (HAB) containing polymers. However, these materials also had low O2 permeabilities, which suggested a tightly packed structure, possibly facilitated by hydrogen bonding. In contrast to suggestions in the literature, the comparison between a polyimide having pendant hydroxyl groups and another having the same repeat unit without them did not reveal a significant change in permselectivity behavior.
The synthesis, characterization and crosslinking behavior of functional polyimides containing phenol, amine and acetylene moieties are also described. A crosslinking reaction of oligomers containing phenol moieties with a tetrafunctional epoxy resin was achieved 100°C below the "dry" glass transition temperature and was attributed to residual solvent. Utilization of this crosslinking mechanism could allow membrane optimization by investigating the influence of a number of variables, such as the concentration of the phenolic moiety, epoxy weight percent, catalyst concentration and residual solvent content.Ph.

Ronsin, Francis. "Du divorce et de la separation de corps en france au 19eme siecle". Paris 7, 1988. http://www.theses.fr/1988PA070002.
Texto completo da fonteResumo:
Jusqu'en 1792, en france, les unions conjugales ne pouvaient etre rompues mais seulement relachees grace a la separation de corps. En 1792, le divorce est autorise et, dans le meme temps, la separation de corps interdite. Le code civil de bonaparte permet de nouveau la separation de corps. En 1816, la restauration interdit le divorce. En 1830, comme en 1848, la liberte du divorce semble devoir etre retablie mais ne le sera finalement pas. Quelques jours avant d'etre ecrasee, la commune avait mis a l'etude le retablissement du divorce. Apres la victoire des republicains aux elections de 1876, les deputes discutent a nouveau du divorce qui est finalement retabli en 1884. Comment ne pas etre stupefait de voir ainsi la legislation du mariage systematiquement remise en cause a chacune des principales dates de l'histoire du 19eme siecle ? cette etroite correlation entre l'histoire des institutions politiques et l'histoire des institutions familiales a certainement ete beaucoup trop negligee par les specialistes de la "grande histoire". Tout aussi surprenant est de constater que si la question du divorce est passionnement debattue par les hommes politiques, les ecrivains, les philosophes sociaux, elle laisse relativement indifferente l'opinion publique. Les donnees statistiques que nous avons traitees montrent que les couples souhaitant leur. .Until 1792, in france, marriage could never be broken but merely loosened thanks to legal separation. In 1792, divorce became lawful and legal separation was forbidden concurrently. The bonaparte civil code authorized legal separation anew. In 1816, under the restauration, divorce was forbidden. In 1830 as well as in 1848, the liberty of divorce seemed likely to be restored but was not, eventually. A few days before being crushed down, the commune had started studying a project to reestablish the right to divorce. After the victory of the republicains at the 1876 election, the deputies debated the project and divorce was eventually re-established in 1884. It is striking to see marriage legislation being challenged at every main date in the history of the 19th century. This close relationship between the history of political institutions and the history of family institutions has been too much overlooked by the specialists of "great" history. And it is no less striking to note that while the divorce question is discussed with passion by the politicians, the writers, the social philosophers, public opinion seems relatively unconcerned. The statistics which we have analysed show that the couples wishing to break off were so few for a long time that they could well be considered as marginal. .

Texto completo da fonteResumo:
We investigate the notion of independence in abstract argumentation, i.e., the question of whether the evaluation of one set of arguments is independent of the evaluation of another set of arguments, given that we already know the status of a third set of arguments. We provide a semantic definition of this notion and develop a method to discover independencies based on transforming an argumentation framework into a DAG on which we then apply the well-known d-separation criterion. We also introduce the SCC Markov property for argumentation semantics, which generalises the Markov property from the classical acyclic case and guarantees the soundness of our approach.

Texto completo da fonteResumo:
Investment in transportation infrastructure projects generates benefits, both direct and indirect. While emissions reductions, crash reductions, and travel time savings are prominent direct benefits, there are indirect benefits in the form of real estate enhancements that could pay off debt or loan incurred in the improvement of the infrastructure itself. Studies have shown that improvements associated with rail transportation (such as station upgrades) trigger an increase in the surrounding real estate values, increasing both the opportunity for monetary gains and, ultimately, property tax collections. There is plenty of available guidance that provides blueprints for benefits calculations for operational improvements in rail transportation. However, resources are quite limited in the analysis of benefits that accrue from the separation of railroad at-grade crossings. Understanding the impact of separation in a neighborhood with high employment or population could generate revenues through increased tax collections. In California, the research need is further amplified by a lack of guidance from the California Public Utilities Commission (CPUC) on at-grade crossing for separation based on revenue generated. There is a critical need to understand whether grade separation projects could impact neighboring real estate values that could potentially be used to fund such separations. With COVID-19, as current infrastructure spending in California is experiencing a reboot, an approach more oriented to benefits and costs for railroad at-grade separation should be explored. Thus, this research uses a robust benefits-to-cost analysis (BCA) to probe the economic impacts of railroad at-grade separation projects. The investigation is carried out across twelve railroad-highway at-grade crossings in California. These crossings are located at Francisquito Ave., Willowbrook/Rosa Parks Station, Sassafras St., Palm St., Civic Center Dr., L St., Spring St. (North), J St., E St., H St., Parkmoor West, and Nursery Ave. The authors found that a majority of the selected at-grade crossings analyzed accrue high benefits-to-cost (BC) ratios from travel time savings, safety improvements, emissions reductions, and potential revenue generated if property taxes are collected and used to fund such separation projects. The analysis shows that with the estimated BC ratios, the railroad crossing at Nursery Ave. in Fremont, Palm St. in San Diego, and H St. in Chula Vista could be ideal candidates for separation. The methodology presented in this research could serve as a handy reference for decision-makers selecting one or more at-grade crossings for the separation considering economic outputs and costs.

Texto completo da fonteResumo:
This report provides an in-depth look at the legal landscape surrounding common-law partnerships in Canada. The recognition and rights afforded to people in common-law relationships depend primarily upon the provincial or territorial jurisdiction. An array of scenarios such as health care decisions, property division upon separation, spousal support claims, inheritance rights, and special considerations for couples living on reserve contribute to the intricate tapestry of legal rights in these relationships. A closer look at the provincial and territorial processes of establishing health care decision-making authority emphasizes that certain jurisdictions do not automatically recognize common-law partners to the same extent as married ones. Moreover, property division rights are absent in several jurisdictions following separation, amounting to different treatment of common-law and married couples. Interestingly, the availability of spousal support post-separation, as well as the guidelines followed by the judges allocating them, are shared by most jurisdictions, with the exception of Quebec. Intestate (without a will) inheritance rights vary considerably, with some regions excluding common-law partners from automatic inheritance. A notable exception arises for couples living under the jurisdiction of the Family Homes on Reserves and Matrimonial Interests or Rights Act (FHRMIRA), highlighting the interactions of federal and regional laws. After highlighting how the rights of common-law partners differ across Canada, this report concludes by raising some of the important dimensions of the current debates on safeguarding the rights of common-law couples.

Texto completo da fonteResumo:
The objective is to develop and evaluate environmental benign agents or products that are effective in the prevention, inhibition, and mitigation of microbially influenced corrosion (MIC) on the internal surfaces of metallic natural gas pipelines. The goal is one or more products that can be applied to maintain the structure and dependability of the natural gas infrastructure. The technical approach for this year has been to evaluate a number of methods to fractionate and concentrate the components found in the pepper extracts. The separation methods considered include size exclusion chromatography, hygroscopic and hydrophobic extraction with HPLC fractionation and analysis; preparative HPLC; and other methods based on the chemical class of compounds to be evaluated. The first classes to be studied are: terpenoids; phenolics; fatty metabolites; alkaloids; and other products of secondary metabolism in plants. Other methods to be reviewed as needed include: planar chromatography; supercritical water and CO2 extraction; and ion-exchange methods. A review of the patent literature and scientific databases found no evidence that any of the potential products have been patented, indicating potential for establishment of a strong intellectual property position. The work plan for the continuation of specific tasks of this project for two additional years was completed and accepted for funding. Laboratory testing protocols for control of biofilm formation and/or biocidal activities for both aerobic and anaerobic microorganisms known to support MIC were codified.

Texto completo da fonteResumo:
This report presents findings of a research effort aimed at reviewing and updating existing Illinois Department of Transportation (IDOT) specifications and manuals regarding the use of geosynthetic materials in pavements. The project consisted of three tasks: evaluate current IDOT practice related to the use of geosynthetics; review research and state of the practice on geosynthetics applications, available products, design methods, and specifications; and propose recommendations for geosynthetic solutions in pavements to modernize IDOT’s practices and manuals. The review of IDOT specifications revealed that geotextiles are the most used geosynthetic product in Illinois, followed by geogrids. Several of IDOT’s manuals have comprehensive guidelines to properly design and construct pavements with geosynthetics, but several knowledge gaps and potential areas for modernization and adoption of new specifications still exist. Based on the review of the available design methods and the most relevant geosynthetic properties and characterization methods linked to field performance, several updates to IDOT’s practice were proposed. Areas of improvement are listed as follows. First, establish proper mechanisms for using geogrids, geocells, and geotextiles in subgrade restraint and base stabilization applications. This includes using shear wave transducers, i.e., bender elements, to quantify local stiffness enhancements and adopting the Giroud and Han design method for subgrade restraint applications. Second, update IDOT’s Subgrade Stability Manual to include property requirements for geogrids, geotextiles, and geocells suitable for subgrade restraint applications. Third, establish proper standards on stabilization, separation, and pumping resistance for geotextiles by incorporating recent research findings on geotextile clogging and permeability criteria. Fourth, promote the use of modern geosynthetic products, such as geotextiles with enhanced lateral drainage, and fifth, elaborate on proper methods for construction/quality control measures for pavements with geosynthetics.

Texto completo da fonteResumo:
In natural gas production and processing applications, methanol is commonly injected into natural gas streams containing water to prevent the formation of hydrates in gas lines and subsequent equipment damage. However, gas chromatographs (GCs) at field sites are typically not equipped to identify or measure methanol, and unless excess methanol is expected to carry over into a gas stream, samples sent to a laboratory are not likely to be analyzed for methanol. As a result, the potential exists for errors in gas property determination, particularly in heating value and sound speed. A previous PRCI project investigated the potential for GCs to quantify methanol as a hydrocarbon, and estimated the resulting errors on heating value and other properties. This theoretical study used assumptions about where methanol would elute on GC columns, but experimental data on GC performance in streams with methanol was unavailable to verify these assumptions. To verify the estimates of the theoretical study, this project collected experimental data on methanol elution behavior in a series of field and laboratory GCs, and established the errors in computed natural gas properties caused by methanol behavior. Three GCs used by the laboratory of a PRCI member company were nominated for testing: ABB NGC 8206 C7+ field GC, Agilent Model 7890A laboratory GC, configured for extended natural gas analysis, and Daniel Model 575 C6+ field GC. The separation columns, valve configurations, and other design features of these GCs that could influence methanol elution were reviewed. Since each GC was predicted to respond differently to methanol, the nominated units were accepted for testing. A fourth GC, a Varian CP-4900 Quad MicroGC outfitted to quantify methanol, was provided to the lab to serve as a reference unit. Hydrocarbon base gas compositions were chosen to represent production and transmission gases and a gas blender was consulted to identify an effective method of stabilizing the methanol content of the test gases delivered to the GCs. Lab personnel and the gas blender then provided the required hardware and the test and calibration gases, with the gas blend compositions traceable to NIST.

Texto completo da fonteResumo:
Many natural gas storage wells suffer damage during normal storage operations. Storage operators spend upwards of $100 million per year recovering lost deliverability. Damage to casings in gas storage wells is largely the result of localized loss of metal from corrosion; however, other types of damage do occur. Individual corrosion pits can be found either on the inside or outside of the casing wall. Repair methods that are currently used for natural gas storage well casings include patches, plugs, liners, etc. While currently-used repair methods can be a cost-effective means of repairing damaged casings as compared to the cost of running an entirely new casing, there is a need to identify and develop alternative casing repair methods that are more economical and/or do not have inherent operational disadvantages. Many of the current repair methods are proprietary, and as a result, are relatively costly to perform. In addition, many of these repair methods (e.g., tube and packer system repairs) result in a decreased cross-sectional area, which creates operational limitations due to flow restrictions and reduces the ability to perform well logging operations. The objective of this project was to review current state-of-the-art casing repair technologies to identify more cost effective alternatives. The most prominent form of underground U.S. gas storage is depleted reservoirs. American Petroleum Institute specification 5CT contains the industry standard design guidance for new casings; however, there are no industry standard repair procedures and each state has their own. The most common state required repair integrity test is pressure testing. Casings must withstand tensile, burst, and collapse loads. Most state repair procedures do not specify a target mechanical property that defines repair success. It is therefore easy to assume that a repair should return a casing back to its original integrity level; however, it may not be necessary. The major types of damage mechanisms are corrosion, threaded connection separation, sealant leaks, split casings, and drill bit damage. While a literature search indicated that the most commonly used types of cost effective repair processes are squeezes, liners, and plating, industry feedback indicated that liner repair is the most commonly used repair process. Adhesively bonded, helically-wound, steel strip repair and magnetic pulse welding are the most promising alternative repair technologies identified, mainly because both are applicable for a broad range of damage types and as an alternative to both traditional casing liner and expandable tubular repair technologies.

Texto completo da fonteResumo:
This study was conducted to determine tensile property variability and its origins in HFERW pipe produced from hot-rolled coils and DSAW pipe produced from plates. Data were collected for DSAW line pipe produced from plates made by flattening coiled skelp. Data have been collected from steelmakers and pipe mills in North America and other countries, including Australia, France, Mexico and Brasil. Results span the most advanced plate and pipe mills to older mills which do not always incorporate modern process control. Data for different steelmaking processes were collected and for different rolling philosophies. A limited amount of data from thin slab product are also presented.
