The Jurisprudence of the European Court of Human Rights: A Score Card for an Effective Enforcement of the Human Rights Regime
Europe has succeeded in principle, in moving from the stage of proclamation of inalienable Human Rights – a gesture of political intent, to that of their effective implementation. Despite a great beginning when the European Convention for the Protection of Human Rights and Fundamental Freedoms (E.C.H.R) was signed in 1956, the path to effective protection of Human Rights has been long and difficult even in Europe. The European Court of Human Rights established in 1959 was the first Independent International Tribunal dedicated to the protection of Human Rights. This article examines the jurisprudence of the European Court of Human Right as a panacea for an effective enforcement of the human rights regime and concludes that the European Courts of Human Rights jurisprudence reaches a good equilibrium on many matters, while on a few others, in the eyes of the present commentator, it could still be improved. Similarly, the court rather than divesting itself of its specific mistake in order to become a general court of cassation of the Council of Europe member states, have instead engaged in a middle way, assigning to itself the role of an essential milestone in the protection and constant development of that branch of law called ‘Human Rights’ and which embodies in some sort, worded general propositions and the essential political and legal commitments of the democratic state of Europe
The Supreme Court of Nigeria Decision in Lufadeju vs Johnson (2007) 8 Nwlr (Pt 1037) P. 535: Whither the Unconstitutionality of Holding Charges in Nigeria?
Pre – trial freedom is indispensable to individual citizens of the world. Nigeria has guaranteed the freedom to liberty as enshrined under section 35 of the Constitution of the Federal Republic of Nigeria 1999. Lagos State of Nigeria in 1994 enacted the Criminal Procedure Law and in the case of Lufadeju vs. Johnson, section 236 (3) of the law which seeks to give powers to the magistrate courts in that State to order for the remand of suspects and or accused persons to prison custody pending when the police would complete their investigations or proper arraignment, came up for interpretation before the Supreme Court of Nigeria and the said law was validated by the court. This paper examines the said decision within the context of whether it has withered the unconstitutionality of holding charges in Nigeria’s criminal justice system and the policy implication of the said decision and concludes that the far reaching pronouncements made by the court are capable of affecting the long aged established rule of the unconstitutionality of holding charges in Nigeria thence perpetuating the incarceration of accused persons in prison custody even where the police are not willing to prosecute which is against the spirit and letters of the Constitution of the Federal Republic of Nigeria 1999. Key words: Remand Proceedings, Holding Charges, Arraignment, Jurisdiction and Liberty.
Understanding Catalyst Design Principles in Transition Metal Mixed Anionic Chalcogenides for Electrocatalytic Energy Conversion
This research focused on the synthetic design of transition metal mixed anionic chalcogenide catalysts containing various ligand types around the central metal atom (chalcogen anion and chalcogen-based organic ligand) generating diverse crystal structure types applied for water splitting and carbon dioxide reduction reactions (CO2RR).
A series of catalysts were synthesized starting with isolated metal complexes (MEn) with a central metal core (M = Co, Ni, Cu, and Cr) through molecular clusters, to bulk nanostructured solids of similar M-E coordination. Bis(dichalcogenoimidodiphosphinato) were employed as ligands in the metal complexes, and anionic chalcogen (E = S, Se, and Te) in bulk solids and metal clusters. This modulates the electron distribution and energy band structure of the catalyst to optimize their performances in electrocatalytic reactions.
The electrochemical oxygen evolution reaction (OER) and hydrogen evolution reaction (HER) performances of cobalt bis(dichalcogenoimidodiphosphinato) complex, chromium molecular cluster, and nickel (telluro) selenide series were studied. Density functional theory was employed to corroborate evolutionary activity trends and to predict OER catalytic performance using a constructed volcano plot in metal chalcogenides.
The molecular chromium carbonyl cluster was studied for electrochemical carbon dioxide reduction reactions (CO2RR). The catalyst is based on 3d early transition metal that was stabilized by bridging μ-Se and CO π-back bonding, increasing the nucleophilic character of the active center. This was capable of transforming CO2 into value-added C2 products and was highly selective with high yield, towards ethanol and acetic acid production at -0.9 and -1.2 V vs RHE potential with high faradaic efficiency -- Abstract, p. i
The Unmanned Killer Machine: The Proliferation of Armed Drones Technology, Strikes and Effects on International Humanitarian and Human Rights Laws
With the advancement of technology the shape and nature of warfare has changed In recent times there has been the proliferation of armed drones technology and its usage From when drones were made operational in the Balkans war they have been used particularly by the US in places like Afghanistan Yemen Somalia and Iraq and controlled by the CIA With these rapid development and proliferations machines are starting to take the place of humans in the battlefield The proliferation and usage of these armed drones poses challenges to the principles of international humanitarian and human rights laws especially when they are operated by non- military personnel like the CIA the parameters of their detention and prosecution This paper therefore analyses the effects that the proliferation and usage of armed drones has on the basic principles of international humanitarian and human rights law and concludes that the ability of armed drones to carry out targeted killings without exercising effective control over territory and without having the individual in custody threatens or presents dangers to the protection of life which is not only a concept of humanity but a human rights violation and posit also that innocent civilians can be killed and indeed have being killed in the process of their usage thence threatening the concept of distinction and proportionality which are some of the cardinal principles of 1HL and thence recommends that there should be the regulation in the manufacture possession and usage of these weapon
Proxcache: A new cache deployment strategy in information-centric network for mitigating path and content redundancy
One of the promising paradigms for resource sharing with maintaining the basic Internet semantics is the Information-Centric Networking (ICN). ICN distinction with the current Internet is its ability to refer contents by names with partly dissociating the host-to-host practice of Internet Protocol addresses. Moreover, content caching in ICN is the major action of achieving content networking to reduce the amount of server access.
The current caching practice in ICN using the Leave Copy Everywhere (LCE) progenerate problems of over deposition of contents known as content redundancy,
path redundancy, lesser cache-hit rates in heterogeneous networks and lower content diversity. This study proposes a new cache deployment strategy referred to as ProXcache to acquire node relationships using hyperedge concept of hypergraph for cache positioning. The study formulates the relationships through the path and distance approximation to mitigate content and path redundancy. The study adopted the Design Research Methodology approach to achieve the slated research objectives. ProXcache was investigated using simulation on the Abilene, GEANT and the DTelekom network topologies for LCE and ProbCache caching strategies with the Zipf distribution to differ
content categorization. The results show the overall content and path redundancy are minimized with lesser caching operation of six depositions per request as compared to nine and nineteen for ProbCache and LCE respectively. ProXcache yields
better content diversity ratio of 80% against 20% and 49% for LCE and ProbCache respectively as the cache sizes varied. ProXcache also improves the cache-hit ratio through proxy positions. These thus, have significant influence in the development of the ICN for better management of contents towards subscribing to the Future Internet
Issued as a Documentation Report on an Investigation of Field-Made Joints in Prestressed Reinforced Concrete Highway Girder Bridges, Project IHR-303, Phase 2
A prototype bridge girder was designed, built, and tested. The 250 ft long two-span
girder was made of 3 precast segments about 88, 74, and 88 ft in length. The
segments were supported on 3 final and 2 temporary supports. The joints were of
cast-in-place concrete, as was the composite deck. After the site-cast concrete
was cured, the structure was post-tensioned to establish continuity and the temporary
supports were removed. The two longer segments were pretensioned to resist
the girder and deck dead loads, while the shorter segment was reinforced with deformed
bars for the same loads.
The structure was subjected to a series of loadings, during which deflections,
reactions, and concrete strains were measured. The loads approximated AASHTO HS-20
vehicles. The first 4 tests ,were to service loads, with total applied loads of
73.6 kips. The structure remained elastic and crack free during these tests. Two
tests were to the design ultimate load, 198.7 kips. A load of 328.2 kips was
applied in the final test without causing failure. The final loading was applied
to produce maximum shear in one splice, and a shear failure, complicated by large
flexural deformations, appeared to be developing when the test ended. The final
test produced a maximum deflection of 10.8 in., and a residual of about 1.0 in.
The joint details used in the prototype structure were adequate, and the presence
of the, joint had no influence on the behavior of the structure until extremely
large overloads were reached.State of Illinois Department of TransportationU.S. Department of Transportation. Federal Highway AdministrationProject IHR-30

Development of Child Restraint Seat Finite Element Model
Child seat is the main safety feature in vehicle meant to protect infants and toddlers in car accident in order to reduce the impact loading transferred to the child occupant in crashes. Virtual crash simulations remain the only tool to optimize safety performance of vehicles at design stage. Crash dummy and vehicles models are created by reverse engineering techniques for application in crash simulations. A restrained child seat Finite Element (FE) model that fits child anthropometry is also required for the crash test. This paper presents the FE modelling of Three Year Old (3YO) child Bebe-confort seat using anthropometric data of 3YO Nigerian child. The CAD model was produced using CATIA software and meshing is done in LS Prepost. The material properties of the child seat frame, belt and foam were extracted from the Bebe-confort seat. Validation was carried out using experimental data of 3YO Hybrid III (HIII) dummy sled test. The response of the dummy in the child FE model qualitatively corresponds well with experimental results and the acceleration time history was also comparable to HIII dummy. Child seat FE model could be used in vehicle safety design for children
Numerical Evaluation of Injuries to Unrestrained Six Year Old Child Passenger in Vehicle Frontal Crash Test
Misuse and not using Child Restraint Seat (CRS) is a norm in some African countries. This work is aimed at evaluating crash injuries of unrestrained Six Year Old (6YO) child in frontal crash. Finite element (FE) crash simulation being valid and cost effective method of crash test of vehicles was employed. The unrestrained dummy model was positioned in car FE model and crash test was conducted in LS DYNA FE software at 48 km/h, in accordance with Federal Motor Vehicle Safety Standard (FMVSS). The results show that unrestrained child experienced Head Injury Criteria (HIC36), HIC15, and chest acceleration (CA) that are 59%, 20% and 2% higher than National Highway Traffic Safety Administration (NHTSA) threshold. Head acceleration (HA) and chest severity index (CSI) were also high for the unrestrained dummy while chest deflection was 40% lower than NHTSA limit which is attributable to dummy characteristics. It was found that unrestrained dummy’s HIC36 and CA are 168% and 20% higher than experimental response of 6YO dummy restrained in Back Kid Backrest Booster from literature, . This quantifies the injury sustained by child passenger seated in a car without CRS for Safety agents to come up with policies to prevent this vulnerable population from avoidable death
