It has been argued that the UK has the reputation of operating a complex set of immigration laws to the extent that the constantly changing laws and regulations lead much to confusion and lack of accountability. It has further been argued that the ever-increasing and shifting pattern of deportation laws (some of which are retroactive) violates the basic principles of human rights norms. This paper aims to raise the query as to whether legislation associated with deportation is constantly enacted and revised to achieve deportation without regard to the remit of the doctrine of legitimate expectation encapsulated under the principle of legal certainty.

This research applies the doctrinal research methodology in addition to somewhat reliance on anecdotal evidence. Doctrinal research is library-based and reliance will be placed on primary and secondary materials such as legislations, case laws, soft laws on the one hand and textbooks, journals, articles, legal encyclopaedia, databases and many valuable websites on the other hand.

While it is accepted that the State enjoys the discretion or prerogative to deport migrants that violate the State’s immigration laws, the author posits that the issue of constant changes breed uncertainty, which in turn breeds unpredictability leading to unaccountability. Drawing on the UK’s state practice, the author will submit that contrivance of deportability and/or removability is adumbrated by the legal production of migrant irregularity exemplified by inconsistent and uncertain laws that vary like the “Chancellor’s foot”. In addition, the research found that crimmigration heightened the velocity of deportation by expanding deportability grounds by way of triggering broader, harsher and more frequent criminal consequences leading to conviction, thereby creating a suitable avenue for deportation and reducing the scope for challenging deportation decisions.

The research is an original piece of work that contributes to scholarship and knowledge in the area of migration as it concerns international human rights law given that wider matters within the boundaries of immigration and nationality laws do have effect on individual possession of rights to be in the UK, by way of lawful presence or as a matter of discretion.

The purpose of this paper is to survey the landscape of recent federal securities class actions filed in state court and explore arguments for removal of those cases to federal courts under the Securities Litigation Reform Act (SLUSA) or the Class Action Fairness Act (CAFA).

The paper discusses: US Congressional legislation designed to bring the bulk of securities class actions back into federal courts, including the Private Securities Litigation Reform Act (PSLRA) and SLUSA; CAFA, another law designed to redirect class action litigation away from state courts; recent cases that have tested the limits of SLUSA and CAFA for removal from state to federal courts; and arguments for removal under SLUSA and CAFA.

Legislative history for both SLUSA and CAFA suggests that these statutes should be read as evidence of Congressional intent to return most securities class actions to federal court. Nonetheless, plaintiffs have continued to devise legal schemes to litigate class actions in what they perceive to be friendlier forums in state courts.

Although the arguments discussed in this paper are not exhaustive, they are a starting point for defendants seeking removal once litigation arises.

The purpose of present paper is to enlarge the knowledge about the performance of gypsum powder to realize complex molds or cores for aluminum casting.

The research was divided into two activities: simple; and complex-part production capability. In the simple-part step, the performance of gypsum powder and the minimum mold thickness that would withstand the casting process. In the complex-part step, the authors first investigated the powder removability as a function of geometry complexity and then binder jetting performance was evaluated for the case of lattice-structure fabrication.

All the geometries tested withstand the casting process demonstrating the benefits in terms of complexity part design; however, the process suffers of all the typical defect of casting as misrun, porosity and cold shut.

The results found in this research improve the benefits related to additive manufacturing application in industrial environment and in particular to the binder jetting technology and the rapid casting approach.

This study aims to focus on the sustainability of prefabricated medical emergency buildings (PMEBs) renovation after the epidemic, to address the problem that large numbers of PMEBs may be abandoned for losing their original architectural functions. This study develops an evaluation system to identify and measure sustainable factors for PMEBs’ renovation schemes. Qualitative and quantitative analysis of PMEBs’ renovation scheme was conducted based on cloud model evaluation method and selected the renovation scheme in line with sustainable development. The study promotes evaluation methods and decision-making basis for the renovation design of global PMEBs and realizes the use-value of building functions again.

By referring to the existing literature, design standards and expert visiting a set of evaluation index systems which combines the renovation of the PMEBs and the sustainability concept has been established, which calculates the balanced optimal comprehensive weight of each indicator utilizing combination weighting method, and quantifies the qualitative language of different PMEBs’ renovation schemes by experts through characteristics of the cloud model. This paper takes Huoshenshan hospital a representative PMEB during the epidemic period as an example, to verify the feasibility of the cloud model evaluation method.

The research results of this paper are that in the PMEBs’ renovation scheme structural reformative (T11) and corresponding nature with the original building (T13) have the most important influence; the continuity of architectural cultural value (T22) and regional development coherence (T23) are the key factors affecting the social dimension; the profitability of renovated buildings (T34) is the key factor affecting the economic dimension; the environmental impact (T41), resource utilization (T42) and ecological technology (T43) are the key factors in the environmental dimension.

This study contributes to the existing body of knowledge by supplementing a set of scientific evaluation methods to make up for the sustainability measurement of PMEBs’ renovation scheme. The main objective was to make renovated PMEBs meet the needs of urban sustainable development, retain the original cultural value of the buildings, meanwhile enhance their social and economic value and realize the renovation with the least impact on the environment.

Unlike other materials, textiles associate with aesthetic and mechanical properties such as flexibility and removability that allow them to be deployed or folded as required and which make them good candidates for clothing and furnishing but also, eventually, for other applications such as building. Actually, the clothing should ensure appropriate heat and mass transfers between the human body and its environment in order to maintain the thermo-physiological comfort. For that, it is important to determine water vapor permeability (WVP) of textile. Several normalized procedures with variants depending on the nature of the tested material exist to measure the WVP. One of the methods used is the “dish method” described by the British Standard (BS 7209). The purpose of this paper is to determine the influence of the test parameters on the WVP measurements.

Consequently, WVP of different textiles was measured while varying several parameters like: nature of fabrics, air layer thickness, vapor pressure gradient and air velocity.

A decrease in the WVP values was observed with an increase in the air layer thickness and the number of textile layers. On the other side, an increase in the water pressure gradient induces an increase in the WVP value. Finally, it was also observed that air velocity has an impact on the WVP measurements.

In addition to intrinsic properties of fabrics, i.e., nature of fiber, woven structure, the influence of the several extrinsic properties, i.e., the influence of the air layer thickness, the number of textile layers, the vapor pressure gradient and the air velocity, on the WVP were investigated. Some researchers have already investigated the impact of these parameters on the WVP measurement separately. However, this study presents a difference from other studies that it takes into account the influence of the both intrinsic and extrinsic properties on WVP. In addition to these, this work combine several extrinsic properties which are presented separately during other studies. The first time, in this study the influence of the air velocity on WVP was investigated. Results on both hydrophilic and hydrophobic fabrics showed a great variation in the results when varying the location of the cups inside the climatic chamber. This is the reason why future studies look at studying more deeply the effect of air velocity on the WVP properties on different types of fabrics by connecting WVP values with air velocity values. It is also planned to make tests with the rotation device and by fixing the value of the temperature and RH. The objective will be to obtain reliable values that do not take into account the effect of air velocity.

This paper looks at the development of prelubes, new coating fluids which can eliminate application of further specialist deep drawing compounds at the press shop. The work carried out by the German Motor Industry, VDA, to establish a specification for prelubes is highlighted, and the full sequence of tests and stages built into this new specification is outlined.

Water‐borne urethanes for the printing ink industry have increased rapidly because they are the best alternative, and not necessarily because of EPA pressure. New developments in urethane chemistry enable the formulation of urethane water‐borne inks that have the adhesion, abrasion resistance, toughness and other necessary properties. The next generation of polymers is already on the drawing board. Close cooperation between the polymer manufacturer and ink formulator can only expand the horizons for this versatile form of polymer.

Adaptability is an inherent quality in building circularity, as adaptability can physically facilitate the reversibility of materials in a closed-reversible chain, also called “loops”. Nevertheless, positioning adaptability in circularity-oriented models could overlook some of the contextual considerations that contribute to the utility for the built environment. This paper reconceptualises building adaptability to incorporate circularity, in order to facilitate for the resource loops whilst preserving the long-lasting functionality in buildings.

An integrative literature review on adaptability and circularity of buildings was conducted using systematic search approach. From the initial database of 4631 publications, 104 publications were included for the final analysis. A comparative analysis of definitions and determinants of both concepts was conducted to reconceptualise circular building adaptability.

The findings of the literature study show that incorporating circularity and adaptability is possible through 10 design and operation determinants, namely configuration flexibility, product dismantlability, asset multi-usability, design regularity, functional convertibility, material reversibility, building maintainability, resource recovery, volume scalability, and asset refit-ability. The study concludes that considering the defined determinants in a holistic manner could simultaneously facilitate: building resilience to contextual changes, creation of asset value, and elimination of waste generation.

This paper expands the relevant bodies of literature by providing a novel way of perceiving building adaptability, incorporating circularity. The practical value of this paper lies in the discussion of potential strategies that can be proactively or reactively employed to operationalise circular building adaptability.

Support structures are often needed in additive manufacturing (AM) to print overhangs. However, they are the extra materials that must be removed afterwards. When the supports have many contacts to the model or are even enclosed inside some concavities, removing them is very challenging and has a risk of damaging the part. Therefore, the purpose of this paper is to develop a new type of tree-support, named Escaping Tree-Support (ET-Sup), which tries to build all the supports onto the build plate to minimize the number of contact points.

The methodology is to first classify the support points into three categories: clear, obstructed and enclosed. A clear point has nothing between it and the build plate; an obstructed point is not clear, but there exists a path for it to reach the build plate; and an enclosed point has no way to reach the build plate. With this classification, the path for the obstructed points to come clear can be found through linking them to the clear points. All the operations are performed efficiently with the help of a ray representation.

The method is tested on different overhang features, including a lattice ball and a mushroom shape with a concave cap. All the supports generated for the examples can find their way to the build plate, which looks like they are escaping from the model. The computation time is around one second for these cases.

This is the first time truly realizing this “escaping” property in the generation of tree-like support structures. With this ET-Sup, it is expected that the AM industries can reduce the manufacturing lead time and save much labor work in post-processing.
