The transition from severe to mild wear in law alloy steel

The wear rates of sliding surfaces are significantly reduced if mild oxidational wear can be encouraged. It is hence of prime importance in the interest of component life and material conservation to understand the factors necessary to promote mild, oxidational wear, The present work investigates the fundamental mechanism of the running-in wear of BS EN 31!EN 8 steel couples. under various conditions of load. speed and test duration. Unidirectional sliding experiments were carried out on a pin-on~disc wear machine where frictional force, wear rate, temperature and contact resistance were continuously monitored during each test. Physical methods of analysis (x-ray, scanning electron microscopy etc.) were used to examine the wear debris and worn samples. The wear rate versus load curves revealed mild wear transitions, which under long duration of running, categorized mild wear into four distinct regions.α-Fe20s. Fe304, FeO and an oxide mixture were the predominant oxides in four regions of oxidational wear which were identified above the Welsh T2 transition. The wear curves were strongly effected by the speed and test duration. A surface model was used to calculate the surface parameters, and the results were found to be comparable with the experimentally observed parameters. Oxidation was responsible for the transition from severe to mild wear at a load corresponding to the Welsh T2 transition. In the running-in period sufficient energy input and surface hardness enabled oxide growth rate to increase and eventually exceeded the rate of removal, where mild wear ensued. A model was developed to predict the wear volume up to the transition. Remarkable agreement was found between the theoretical prediction and the experimentally-measured values. The oxidational mechanjsm responsible for transitjon to mild wear under equilibrium conditions was related to the formation of thick homogenous oxide plateaux on subsurface hardened layers, FeO was the oxide formed initially at the onset of mild wear but oxide type changed.during the total running period to give an equilibrium oxide whose nature depended on the loads applied.

Justice and morality:human suffering, natural law and international politics

Bridging the contending theories of natural law and international relations, this book proposes a 'relational ontology' as the basis for rethinking our approach to international politics. The book contains a number of challenging and controversial ideas on the study of international political thought which should provoke constructive debate within international relations theory, political theory, and philosophical ethics. © Amanda Russell Beattie 2010.

Trademarks with a reputation:bridging the 'logical lapse'

The article focuses on the Trade Marks Regulations 2004, which came into force on May 5, 2004. Regulation 7 repeals s 5(3)(b) and amends s 10(3) of the Trade Marks Act 1994, implementing the decision of the European Court of Justice in Davidoff & Cie SA and Zino Davidoff SA v Gofkid Ltd., which was then confirmed in Adidas-Salomon AG and Adidas Benelux BV v Fitnessworld Trading Ltd. The orthodox definition of the primary and proper function of a trademark is that it is to identify the origin or ownership of the goods to which the mark is affixed. As society has changed so too have the functions of the trademark. Due to increased affluence and the growth of the consumer society, some trademarks may now have achieved the status of being a symbol of desire in their own right.

Bridging the gap between stylistic and cognitive approaches to authorship analysis using systemic functional linguistics and multidimensional analysis

In the present state of the art of authorship attribution there seems to be an opposition between two approaches: cognitive and stylistic methodologies. It is proposed in this article that these two approaches are complementary and that the apparent gap between them can be bridged using Systemic Functional Linguistics (SFL) and in particular some of its theoretical constructions, such as codal variation. This article deals with the theoretical explanation of why such a theory would solve the debate between the two approaches and shows how these two views of authorship attribution are indeed complementary. Although the article is fundamentally theoretical, two example experimental trials are reported to show how this theory can be developed into a workable methodology of doing authorship attribution. In Trial 1, a SFL analysis was carried out on a small dataset consisting of three 300-word texts collected from three different authors whose socio-demographic background matched across a number of parameters. This trial led to some conclusions about developing a methodology based on SFL and suggested the development of another trial, which might hint at a more accurate and useful methodology. In Trial 2, Biber's (1988) multidimensional framework is employed, and a final methodology of authorship analysis based on this kind of analysis is proposed for future research. © 2013, EQUINOX PUBLISHING.

Az üzletrész másokat megelőző megszerzésére irányuló jog és a vételi jog konkurenciájáról

Sem a korábbi Gt.-k, sem a hatályos Ptk. tételesen nem rendelkezik arról, hogy üzletrészre kiköthető-e vételi jog. Ettől függetlenül, az üzleti, illetve a bírói gyakorlatban ismert, illetve elismert, hogy az üzletrészre vételi jogot lehet alapítani. Jelen munka elsőként azt vizsgálja, hogy a hatályos Ptk.-nak ’az üzletrész pénzszolgáltatás ellenében történő átruházása’ és az ’üzletrész másokat megelőző megszerzésére irányuló jog’ fordulatai milyen értelmezési kérdéseket vetnek fel. Az írás ezt követően pedig azt tárgyalja, hogy hogyan alakul az üzletrész másokat megelőző megszerzésére irányuló jog és a vételi jog egymáshoz való viszonya abban az esetben, ha a társaság tagja olyan üzletrészre, amelyen más tag(ok)nak a Ptk. 3:167. §-a alapján az üzletrész másokat megelőző megszerzésére irányuló joga áll fenn, más személy javára szerződéssel vételi jogot enged. Jelen munka e kérdésben épített Metzinger Péter Az elővásárlási és a vételi jog konkurenciájáról címmel, a Corvinus Law Papers 2016/1. számában megjelent tanulmányának következtetéseire, illetve továbbgondolta azokat az üzletrész másokat megelőző megszerzésére irányuló jog és a vételi jog konkurenciája szempontjából.

The star formation and extinction coevolution of UV-selected galaxies over 0.05 < z < 1.2

We use a new stacking technique to obtain mean mid-IR and far-IR to far-UV flux ratios over the rest-frame near-UV, near-IR color-magnitude diagram. We employ COMBO-17 redshifts and COMBO-17 optical, GALEX far- and near-UV, and Spitzer IRAC and MIPS mid-IR photometry. This technique permits us to probe the infrared excess (IRX), the ratio of far-IR to far-UV luminosity, and the specific star formation rate (SSFR) and their coevolution over 2 orders of magnitude of stellar mass and over redshift 0.1 < z < 1.2. We find that the SSFR and the characteristic mass (Script M_0) above which the SSFR drops increase with redshift (downsizing). At any given epoch, the IRX is an increasing function of mass up to Script M_0. Above this mass the IRX falls, suggesting gas exhaustion. In a given mass bin below Script M_0, the IRX increases with time in a fashion consistent with enrichment. We interpret these trends using a simple model with a Schmidt-Kennicutt law and extinction that tracks gas density and enrichment. We find that the average IRX and SSFR follow a galaxy age parameter ξ, which is determined mainly by the galaxy mass and time since formation. We conclude that blue-sequence galaxies have properties which show simple, systematic trends with mass and time such as the steady buildup of heavy elements in the interstellar media of evolving galaxies and the exhaustion of gas in galaxies that are evolving off the blue sequence. The IRX represents a tool for selecting galaxies at various stages of evolution.

Migrant domestic workers, vulnerability and the law: immigration and employment laws in Cyprus and Spain

The intersection of gender, welfare and immigration regimes has been one of the main focus of a rich scholarship on paid domestic work in Europe. This article brings into the discussion the nexus of employment and immigration law regimes to reflect on the role of legal regulation in structuring and reducing the vulnerability of domestic workers. I analyse this nexus by looking at the cases of Cyprus and Spain, two states falling under the cluster of Southern Mediterranean welfare regimes, that share certain characteristics in terms of immigration regimes, but have substantially different employment law regulation models. The first part sketches the debate on the employment law regulation of domestic work. The second part starts by giving an overview of the immigration regimes of Cyprus and Spain in relation to migrant domestic workers and then proceeds to analyse the two countries’ models and substance of employment law regulation in domestic work. The comparison of these two divergent approaches informs the debate on how the legal regulation of domestic work should be best structured. In Spain there have been recent dynamic legislative changes in the employment law regulation of domestic work. The final part of the article traces these changes and reflects on why such processes have not taken place in Cyprus.

Udział stowarzyszeń zwykłych w postępowaniu sądowoadministracyjnym w sprawach z zakresu ochrony środowiska – analiza rozbieżności w orzecznictwie

Participation of unincorporated associations in court and administrative proceedings is a tool of public participation which is a part of basic principles of performance of a democratic country and a civil society. By means of abiding by those principles administrative bodies and courts respect the rule of law and it becomes a standard. The rule of public participation can be as well treated as a part of the basic civil rights stipulated in the Constitution. By respecting the right of unincorporated associations to participate in court and administrative proceedings in environmental protection-related cases the goals and functions of environmental protection law can be accomplished.

Teoretycznoprawne aspekty operacjonalizacji ochrony praw człowieka w państwie z perspektywy globalnego systemu prawa (Zarys problematyki)

The article is devoted to the presentation of the outline of the concept of operationalization of human rights taking place in the states involved in the system of international protection of those rights. The concept of operationalization of protection is a collective term for a series of processes that lead to the establishment of legal provisions protecting human rights, and to transfer this abstract construct to specific societies. It includes both the decision-making processes of extralegal (uprising idea, its conceptualization, social issues and change the perception of axiology of society, cultural aspects) and legal (lawmaking and law application processes in the aspect of human rights and the impact of international institutions on them) character. The essence of the process of operationalization is providing effective protection of human rights in a state. The concept is set primarily on the consequences of membership of Poland in the system of the Council of Europe.

Kwestia niekonstytucyjności roszczenia informacyjnego z art. 2861 p.w.p. – wybrane zagadnienia

Roszczenie informacyjne jest instrumentem prawnym, przy pomocy którego uprawniony z tytuł prawa do patentu, prawa ochronnego na wzór użytkowy, prawa z rejestracji wzoru przemysłowego czy też prawa ochronnego na znak towarowy może domagać się, aby sąd zobowiązał określony podmiot do ujawnienia informacji, które są niezbędne dla skutecznego dochodzenia roszczeń przed sądem. Niejednokrotnie bowiem ze względu na niematerialny charakter praw własności przemysłowej ustalenie naruszyciela tych praw oraz skali samego naruszenia jest znacznie utrudnione. Wokół tytułowego roszczenia informacyjnego na gruncie ustawy Prawo własności przemysłowej powstało szereg kontrowersji, którego zwieńczeniem było wniesienie skargi konstytucyjnej w 2015 roku, oczekującej obecnie na rozstrzygnięcie przez Trybunał Konstytucyjny. Realizacja roszczenia tego rodzaju powoduje bowiem, że ochrona praw podmiotu uprawnionego prowadzi nieuchronnie do ograniczenia praw innego podmiotu – zobowiązanego do udzielenia informacji. Wobec tego szczególnie istotne jest respektowanie zasady proporcjonalności przy ustanawianiu ograniczeń praw i wolności obywatelskich. W niniejszym opracowaniu została rozważona zasadność zarzutów niekonstytucyjności omawianej instytucji prawnej i jej zgodności m.in. z prawem do sądu oraz wolnością działalności gospodarczej w zestawieniu z zasadą proporcjonalności ograniczenia praw konstytucyjnych. Na tle wątpliwości co do zgodności z Konstytucją roszczenia informacyjnego przedstawione zostały także kwestie dotyczące wadliwości implementacji dyrektywy unijnej w zakresie roszczenia o udzielenie informacji. Wszystkie zagadnienia zostały omówione na tle stosunków gospodarczych, w jakich uczestniczą podmioty uprawnione do żądania udzielenia informacji, a także zobowiązane do ich udzielenia.

Glosa do postanowienia Naczelnego Sądu Administracyjnego z dnia 13 stycznia 2016 r., sygn. akt II GZ 927/15

W glosowanym orzeczeniu Naczelny Sąd Administracyjny stwierdził, że od postanowień wojewódzkich sądów administracyjnych odrzucających skargi z przyczyn formalnych w sprawach wszczętych przed dniem wejścia w życie nowelizacji Prawa o postępowaniu przed sądami administracyjnymi (co miało miejsce 15 sierpnia 2015 r.) przysługuje zażalenie, a nie skarga kasacyjna. Przedmiotowe zagadnienie prawne sprowadza się do właściwej wykładni źle sformułowanych przepisów intertemporalnych. W glosie zaprezentowano istotę środków odwoławczych w postępowaniu sądowoadministracyjnym i scharakteryzowano krótko ostatnią nowelizację Prawa o postępowaniu przed sądami administracyjnymi. Autor prezentuje stanowisko krytyczne w stosunku do tezy postanowienia Naczelnego Sądu Administracyjnego, wskazując, że sąd powinien rozstrzygnąć sprawę co do jej istoty. Pogląd ten został poparty odpowiednią argumentacją z uwzględnieniem konkurencyjnego orzecznictwa Naczelnego Sądu Administracyjnego.

Breaking the curve with candels: a Bayesian approach to reveal the non-universality of the dust-attenuation law at high redshift

Dust attenuation affects nearly all observational aspects of galaxy evolution, yet very little is known about the form of the dust-attenuation law in the distant universe. Here, we model the spectral energy distributions of galaxies at z ~ 1.5–3 from CANDELS with rest-frame UV to near-IR imaging under different assumptions about the dust law, and compare the amount of inferred attenuated light with the observed infrared (IR) luminosities. Some individual galaxies show strong Bayesian evidence in preference of one dust law over another, and this preference agrees with their observed location on the plane of infrared excess (IRX, L_TIR/L_UV) and UV slope (β). We generalize the shape of the dust law with an empirical model, A_ λ,σ =E(B-V)k_ λ (λ / λ v)^ σ where k_λ is the dust law of Calzetti et al., and show that there exists a correlation between the color excess E(B-V) and tilt δ with δ =(0.62±0.05)log(E(B-V))+(0.26±0.02). Galaxies with high color excess have a shallower, starburst-like law, and those with low color excess have a steeper, SMC-like law. Surprisingly, the galaxies in our sample show no correlation between the shape of the dust law and stellar mass, star formation rate, or β. The change in the dust law with color excess is consistent with a model where attenuation is caused by scattering, a mixed star–dust geometry, and/or trends with stellar population age, metallicity, and dust grain size. This rest-frame UV-to-near-IR method shows potential to constrain the dust law at even higher redshifts (z>3).
