We addressed the research question, how does the host community perceive theeffects of Rohingya influx to Bangladesh, from their perspectives using a questionnairesurvey, key informant interviews, and focus group discussions. Bangladesh shelteredover a million Rohingyas, fleeing genocide and serious crimes against humanity, onhumanitarian grounds. The local people welcomed them and offered direct supportand assistance. Our findings suggest that their immediate sympathy for Rohingyasfaded over time due to various factors. An overwhelming majority perceived theRohingyas as pressure on their land and resources and being deprived on numerousgrounds outweighed the disproportionate economic incentives of the influx. Thefindings offer fresh insights into the challenges of hosting refugees in the localcommunities because of the diverse impacts of forced displacement.

Key Legal Issues Surrounding Smart Contract Applications
Pablo Sanz Bayón 한국법제연구원 2019 KLRI journal of law and legislation Vol.9 No.1
The aim of this work is to delve into some key legal issues surrounding Smart Contract applications. In the first and second parts, this paper defines the concept of Smart Contract and how it applies within the blockchain ecosystem. In the third part, this work exposes the functioning of this digital technology and the main advantage that it implies for solving the crucial issues of execution and breach of contracts. In the fourth section, this paper analyzes a set of problematic aspects that arise around Smart Contracts such as the scope and delimitation of them or the validity and certification of blockchain transactions. It also analyzes different issues related to the design of a legislative policy that addresses the design of a supranational and harmonized legal framework.
Nonlinear bending vibration of a prestressed thick plate
Francisco J. Nieves,Ana Bayón,Francisco Gascón,Rafael Medina,Félix Salazar 대한기계학회 2018 JOURNAL OF MECHANICAL SCIENCE AND TECHNOLOGY Vol.32 No.4
In this paper, the flexural vibration frequency in the antisymmetric mode of a thick plate as a function of the amplitude of the vibration and the axial force applied is investigated. With this aim, the theory of geometrically nonlinear deformation of second order and an optimized three-dimensional Ritz method are used. The plate is homogeneous, elastically linear, free from any constraints, and subjected to axial forces uniformly distributed on two of its opposite sides. Several approaches are discussed. First, the problem based on finite stress and infinitesimal strains is solved. Second, the deformation energy is assumed as the energy in the initial state plus the vibration energy of small or large amplitude. Third, without assumptions about the size of the deformation and of the vibration amplitude, the theory of nonlinear deformation is employed. Finally, numerical calculations for free vibration are compared with experimental results, including their systematic uncertainties.

Heterophilic antibodies are human immunoglobulins directed against various animal antigens. They can produce false-positive results in the analysis of different tumor markers, including prostate-specific antigen. This interference can lead to misdiagnosis, unnecessary tests, and overtreatment in some cases. We present herein the case of a 52-year-old man with repeated spurious elevation of prostate-specific antigen, reaching levels of 108.7 ng/mL, that were suspected to be caused by heterophilic antibodies. The interference was solved by changing the analysis technique. Real values of prostate-specific antigen were less than 1 ng/mL.

<P><B>Abstract</B></P> <P>Cobalt (Co) nanoparticle supported catalysts have better dispersion and recyclability than unsupported Co. However, the surface chemistry and limited surface area (SA) of supports limit their Co loading which lowers activity. Currently, supports with high SA and functionality which allow high Co loading are been developed. However, a smarter solution would be to develop “active” supports which can boost the activity of Co, even at low loading. The value of such a support lies in the ability to use low catalyst loading without scarifying activity. Herein, we demonstrate how via a simple annealing process the chemical properties of Fe<SUB>3</SUB>O<SUB>4</SUB> and physico-electrical properties of carbon (C) in Fe<SUB>3</SUB>O<SUB>4</SUB>@C can be effectively combined to prepare an “active” support for Co. The unique properties of the “active” Fe<SUB>3</SUB>O<SUB>4</SUB>@C triggers a synergistic catalytic reaction involving Co, Fe<SUB>3</SUB>O<SUB>4</SUB> and C during NaBH<SUB>4</SUB> hydrolysis. Consequently, the hydrogen generation rate (1746 ml g<SUP>−1</SUP> min<SUP>−1</SUP>) and activation energy (47.3 kJ mol<SUP>−1</SUP>) of Fe<SUB>3</SUB>O<SUB>4</SUB>@C-Co are significantly enhanced compared to reported catalyst even though its Co loading is significantly lower. Additionally, Fe<SUB>3</SUB>O<SUB>4</SUB>@C-Co is highly recyclable which demonstrates its stability. Our study gives a new perspective on the role supports can play in catalyst design.</P> <P><B>Graphical abstract</B></P> <P>The synergistic catalytic property on Fe<SUB>3</SUB>O<SUB>4</SUB>@C-Co towards NaBH<SUB>4</SUB> hydrolysis.</P> <P>[DISPLAY OMISSION]</P>
