'Rule of Law and Politics of Anti-Corruption Campaigns in a Post-Authoritarian State- The Nigerian Case'

This article evaluates the anti-corruption campaign instituted in Nigeria following on the post-authoritarian transition in the country, with specific focus on political corruption. The anti-corruption campaign is being prosecuted within a context where law is as critical a factor as politics. This article examines whether the judiciary, in view of its accountability deficit, can offer legitimacy to the campaign. How has its questionable credentials impacted on its involvement in the campaign to sanitise public life? What has been the impact of the judicial role on the rule of law? These are some of the important questions this article seeks to answer. The inquiry in this article demonstrates how the guardian institution of the rule of law faces an uphill task in the performance of that role in a post-authoritarian context.

A computerized audit of non-steroidal anti-inflammatory drug prescribing in general practice

The two group practices based in a city health centre decided to prescribe non-steroidal anti-inflammatory drugs in generic form from an agreed date. The practices' computer was used to identify the number of repeat prescriptions being issued for this group of drugs and to monitor the effectiveness of the changeover. Although both practices showed a marked increase in the level of generic prescribing there was considerable interpractice variation. Generic prescribing for one practice increased from 4% to 64% and for the other from 1% to 38% of repeat prescriptions issued for non-steroidal anti-inflammatory drugs over the study period. The reasons for this variation, the advantages of computerized audit and the problems associated with this self-imposed audit are discussed.

Avoidance Techniques: State Related Defences in International Antitrust Cases

Despite its economic significance, competition law still remains fragmented, lacking an international framework allowing for dispute settlement. This, together with the growing importance of non-free-market economies in world trade require us to re-consider and re-evaluate the possibilities of bringing an antitrust suit against a foreign state. If the level playing field on the global marketplace is to be achieved, the possibility of hiding behind the bulwark of state sovereignty should be minimised. States should not be free to act in an anti-competitive way, but at present the legal framework seems ill-equipped to handle such challenges.

This paper deals with the defences available in litigation concerning transnational anti-competitive agreements involving or implicating foreign states. Four important legal doctrines are analysed: non-justiciability (political question doctrine), state immunity, act of state doctrine and foreign state compulsion. The paper addresses also the general problem of applicability of competition laws to a foreign state as such. This is a tale about repetitive unsuccessful efforts to sue OPEC and recent attempts in the US to deal with export cartels of Chinese state-owned enterprises

Coronavirus Main Proteinase (3CLpro) Structure: Basis for Design of Anti-SARS Drugs

A novel coronavirus has been identified as the causative agent of severe acute respiratory syndrome (SARS). The viral main proteinase (Mpro, also called 3CLpro), which controls the activities of the coronavirus replication complex, is an attractive target for therapy. We determined crystal structures for human coronavirus (strain 229E) Mpro and for an inhibitor complex of porcine coronavirus [transmissible gastroenteritis virus (TGEV)] Mpro, and we constructed a homology model for SARS coronavirus (SARS-CoV) Mpro. The structures reveal a remarkable degree of conservation of the substrate-binding sites, which is further supported by recombinant SARS-CoV Mpro-mediated cleavage of a TGEV Mpro substrate. Molecular modeling suggests that available rhinovirus 3Cpro inhibitors may be modified to make them useful for treating SARS.

Anti-sized reed bed system for animal wastewater treatment: a comparative study

This paper presents a comparative study on the treatment of high-strength animal wastewater in two parallel lab-scale constructed reed bed systems, progressively-sized system and anti-sized system, which have same configuration but different arrangement of bed media. The reed bed systems were operated in a tidal flow pattern to treat diluted pig slurry. Detailed analyses were carried out for the removal of some key pollutants including COD, BOD5, NH4-N, P and suspended solids. The results showed that both systems have considerable capacity for the removal of solids, organic matter and inorganic nutrients. The formation of biofilms on the surfaces of gravel media in both reed bed systems was monitored by scanning selected gravel samples using scanning electron microscopy. In general, no significant difference was detected with regard to the percentage pollutant removal in the systems. However, the anti-sized system demonstrated a clear advantage in its ability to slow down the clogging of bed media and avoid the impairment of long-term functioning and sustainability of the beds. A conceptual model was developed to predict the occurrence of the clogging. The validity of the model was tested using data from this study and from the literatures.

Chemoenzymatic synthesis of the trans-dihydrodiol isomers of monosubstituted benzenes via anti-benzene dioxides

Enantiopure cis-2,3-dihydrodiols, available from dioxygenase-catalysed cis-dihydroxylation of monosubstituted benzene substrates, have been used as synthetic precursors of the corresponding trans-3,4-dihydrodiols. The six-step chemoenzymatic route from cis-dihydrodiol precursors, involving acetonide, tetraol, dibromodiacetate and diepoxide intermediates, and substitution of vinyl bromide and iodide atoms, has been used in the synthesis of ten trans-dihydrododiol derivatives of substituted benzenes. The general applicability of the method has been demonstrated by its use in the synthesis of both enantiomers of the trans-1,2- and 3,4-dihydrodiol derivatives of toluene.

Animal group forces resulting from predator avoidance and competition minimization

A new model to explain animal spacing, based on a trade-off between foraging efficiency and predation risk, is derived from biological principles. The model is able to explain not only the general tendency for animal groups to form, but some of the attributes of real groups. These include the independence of mean animal spacing from group population, the observed variation of animal spacing with resource availability and also with the probability of predation, and the decline in group stability with group size. The appearance of "neutral zones" within which animals are not motivated to adjust their relative positions is also explained. The model assumes that animals try to minimize a cost potential combining the loss of intake rate due to foraging interference and the risk from exposure to predators. The cost potential describes a hypothetical field giving rise to apparent attractive and repulsive forces between animals. Biologically based functions are given for the decline in interference cost and increase in the cost of predation risk with increasing animal separation. Predation risk is calculated from the probabilities of predator attack and predator detection as they vary with distance. Using example functions for these probabilities and foraging interference, we calculate the minimum cost potential for regular lattice arrangements of animals before generalizing to finite-sized groups and random arrangements of animals, showing optimal geometries in each case and describing how potentials vary with animal spacing.

Repeat prescribing of non-steroidal anti-inflammatory drugs excluding aspirin:how careful are we?

About 5% of all National Health Service prescriptions in Britain and a quarter of reports of suspected adverse reactions are accounted for by non-steroidal anti-inflammatory drugs. Their prescription was investigated in two computerised group practices serving 11850 patients. Altogether 198 patients receiving repeat prescriptions of non-steroidal anti-inflammatory drugs were identified and relevant clinical details extracted from their notes. Of these patients, 119 were over 65 years old; 172 were receiving one of six different non-steroidal anti-inflammatory drugs; and 76 were taking drugs that can interact with non-steroidal anti-inflammatory drugs. Ninety one patients had one or more medical conditions that may be aggravated by non-steroidal anti-inflammatory drugs, and 36 had experienced side effects important enough for their treatment to be changed. A questionnaire to assess opinions and knowledge of non-steroidal anti-inflammatory drugs was given to 42 general practitioners and 26 rheumatologists. Although the two groups showed a comparable knowledge of the properties and costs of non-steroidal anti-inflammatory drugs, they differed significantly in their views on the circumstances under which these drugs should be used. Clear guidelines on the prescription of these drugs would indicate when careful monitoring is essential for patients to benefit from them safely.

Appealing to the Republic of Letters: An Autopsy of Anti-venereal Trials in Eighteenth-century Mexico

This study analyses the narrative elements of a little-known report into anti-venereal trials written by an Irish military physician-surgeon, Daniel O'Sullivan (1760–c.1797). It explores the way in which O'Sullivan as the narrator of the Historico-critical report creates medical heroes and anti-heroes as a means to criticise procedures initiated by staff in the Hospital General de San Andrés, Mexico City. The resulting work depicts a much less positive picture of medical trials and hospital authorities in this period than has been recorded to date, and provides a critical and complicated assessment of one of Spain's leading physicians of the nineteenth century, Francisco Javier Balmis (1753–1819).

Non-steroidal anti-inflammatory drug use and brain tumour risk:a case-control study within the Clinical Practice Research Datalink

Purpose: The aetiology of primary brain tumours is largely unknown; the role of non-steroidal anti-inflammatory drugs (NSAIDs) or aspirin use and glioma risk has been inconclusive, but few population-based studies with reliable prescribing data have been conducted, and the association with meningioma risk has yet to be assessed. Methods: The UK Clinical Practice Research Datalink was used to assess the association between aspirin and non-aspirin NSAID use and primary brain tumour risk using a nested case-control study design. Conditional logistic regression analysis was performed on 5,052 brain tumour patients aged 16 years and over, diagnosed between 1987 and 2009 and 42,678 controls matched on year of birth, gender and general practice, adjusting for history of allergy and hormone replacement therapy use in the glioma and meningioma models, respectively.

Results: In conditional logistic regression analysis, excluding drug use in the year preceding the index date, there was no association with non-aspirin NSAID use (OR 0.96, 95 % CI 0.81-1.13) or glioma risk comparing the highest category of daily defined dose to non-users; however, non-aspirin NSAID use was positively associated with meningioma risk (OR 1.35, 95 % CI 1.06-1.71). No association was seen with high- or low-dose aspirin use irrespective of histology.

Conclusions: This large nested case-control study finds no association between aspirin or non-aspirin NSAID use and risk of glioma but a slight increased risk with non-aspirin NSAIDs and meningioma. © 2013 Springer Science+Business Media Dordrecht.

A statistical process control approach for automatic anti-islanding detection using synchrophasors

Anti-islanding protection is becoming increasingly important due to the rapid installation of distributed generation from renewable resources like wind, tidal and wave, solar PV, bio-fuels, as well as from other resources like diesel. Unintentional islanding presents a potential risk for damaging utility plants and equipment connected from the demand side, as well as to public and personnel in utility plants. This paper investigates automatic islanding detection. This is achieved by deploying a statistical process control approach for fault detection with the real-time data acquired through a wide area measurement system, which is based on Phasor Measurement Unit (PMU) technology. In particular, the principal component analysis (PCA) is used to project the data into principal component subspace and residual space, and two statistics are used to detect the occurrence of fault. Then a fault reconstruction method is used to identify the fault and its development over time. The proposed scheme has been used in a real system and the results have confirmed that the proposed method can correctly identify the fault and islanding site.
