Assessment of the Socio Economic and Political Implications of ECOWAS Free Movement

This paper examines the extent the ECOWAS free movement protocol of persons, goods and services contributes to the economic and political growth of Nigeria which is an active member state. The protocol on free movement is often hijacked by criminals from some member states, neighbors and within to perpetrate trans-border crimes such as smuggling of arms, drugs and other forms of crimes. Political development is the heart beat of other development in any country. This is because power rest in political sphere and it is through power that other development such as economic development rest. The system of government in place, the ideals of the government and the stability of the government determine the profitable, societal plus cultural improvement of the nation. The role plays by civil societies, mass media and some section of activists toward the return to democracy in Nigeria are more appreciated and noticeable than that of ECOWAS. This indicates that there is always romance between ECOWAS and West African dictators especially in Nigeria. This unholy relationship might not be far from the fact that most leaders under ECOWAS are once dictators who benefited from the silence of the community or the leaders are mute considering the benefit their individual states get from dictators in Nigeria. The study primarily adopted the desk research design which involves the use of secondary source of data. The analyses of the data were carried out using content analysis. The study revealed that the performance of ECOWAS were undermined by various factors such as lack of political will, fear and mutual distrust, cultural and colonial differences among others. These factors inhibited the full actualization of the protocol among member states. The study concluded that Nigerian government should evaluate her activities in ECOWAS and should ensure that member states contribute their quota to the community as enshrine in the treaty.

Impact of a multimodal rehabilitative intervention on demented patients and their caregivers

Alzheimer's disease is becoming a social, political, and economic issue as a result of both the growing number of people affected and the enormous economic, social, and emotional costs involved in caring for Alzheimer's patients. The aim of this study is to evaluate the effects of a multimodal intervention program for patients with Alzheimer's disease and their caregivers. The study was conducted on a sample of 32 subjects: 16 Alzheimer's patients and their caregivers. The results obtained after the multimodal rehabilitation program showed that the Alzheimer's patients had a more stable cognitive status and improved mood. Regarding the psychoeducational program, the results demonstrate the efficacy of such interventions in terms of increasing and preserving the caregivers' coping skills and enhancing their perception of the value of support groups

Determination of carbonyl compounds in exhaled breath by on-sorbent derivatization coupled with thermal desorption and gas chromatography-tandem mass spectrometry

A reliable method for the determination of carbonyl compounds in exhaled breath based on on-sorbent derivatization coupled with thermal desorption and gas chromatography-tandem mass spectrometry is described. The analytical performances were optimized for a mixture of C2-C9 aldehydes and C3-C9 ketones, particularly interesting for clinical applications, by using an internal standard and applying a 2^3 full factorial design. A volume of sample (250 ml) was loaded at 50 ml min-1 into a Tenax GR sorbent tube containing 130 nmol of O-(2,3,4,5,6-pentafluorobenzyl)hydroxylamine hydrochloride. All compounds showed a limit of detection lower than 200 pptv. The yield of the derivatization procedure was normalized by adding to the sample a known amount of 6D-acetone as an internal standard. This allowed halving the relative standard deviation to 10% and 15% for the mono-and di-carbonyl compounds, respectively, thus improving reliability. The optimized method was applied to the determination of carbonyl compounds in 12 breath samples collected from four patients suffering from heart failure during hospitalization

Toxicity of thallium at low doses: A review

A mini review of the toxicity of Thallium (Tl) at low doses is herein presented. Thallium has severe toxicity. Although its acute biological effects have been widely investigated and are well known, its biological effects on human health and in cell cultures at low doses (<100 µg/L) due, for example, to Tl chronic exposure via consumption of contaminated water or foods, have often been overlooked or underestimated. Relatively few papers have been published on this topic and are herein reviewed to provide a focused scientific opinion in the light of current worldwide regulatory issues

Hexavalent chromium release over time from a pyrolyzed Cr-bearing tannery sludge

Pyrolysis in an inert atmosphere is a widely applied route to convert tannery wastes into reusable materials. In the present study, the Cr(III) conversion into the toxic hexavalent form in the pyrolyzed tannery waste referred to as KEU was investigated. Ageing experiments and leaching tests demonstrated that the Cr(III)–Cr(VI) inter-conversion occurs in the presence of air at ambient temperature, enhanced by wet environmental conditions. Microstructural analysis revealed that the Cr-primary mineral assemblage formed during pyrolysis (Cr-bearing srebrodolskite and Cr-magnetite spinel) destabilized upon spray water cooling in the last stage of the process. In the evolution from the higher to the lower temperature mineralogy, Cr is incorporated into newly formed CrOOH flakes which likely react in air forming extractable Cr(VI) species. This property transforms KEU from an inert waste to a hazardous material when exposed to ordinary ambient conditions

Evaluation of microbial adhesion and biofilm formation on nano-structured and nano-coated ortho-prosthetic materials by a dynamic model

The bio-engineering technologies of medical devices through nano-structuring and coating was recently proposed to improve biocompatibility and to reduce microbial adhesion in the prevention of implantable device-related infections. Our aim was to evaluate the ability of new nano-structured and coated materials to prevent the adhesion and biofilm formation, according to the American Standard Test Method ASTM-E2647-13. The materials composition was determined by X-ray Fluorescence and Laser Induced Breakdown Spectroscopy. Silver release was evaluated by Inductively Coupled Plasma Mass Spectrometry analysis. The gene expression levels of the Quorum Sensing Las and Rhl system were evaluated by the ΔΔCt method. The Log bacterial density (Log CFU/cm2) on TiAl6V4 was 4.41 ± 0.76 and 4.63 ± 1.01 on TiAl6V4-AgNPs compared to 2.57 ± 0.70 on CoCr and 2.73 ± 0.61 on CoCr-AgNPs (P < 0.0001, A.N.O.V.A.- one way test). The silver release was found to be equal to 17.8 ± 0.2 μg/L after the batch phase and 1.3 ± 0.1 μg/L during continuous flow. The rhlR gene resulted in a 2.70-fold increased expression in biofilm growth on the silver nanoparticles (AgNPs) coating. In conclusion, CoCr showed a greater ability to reduce microbial adhesion, independently of the AgNPs coating. The silver release resulted in promoting the up-regulation of the Rhl system. Further investigation should be conducted to optimize the effectiveness of the coating

The Heart of the Matter. About Good Nursing and Telecare

Nurses and ethicists worry that the implementation of care at a distance or telecare will impoverish patient care by taking out ‘the heart’ of the clinical work. This means that telecare is feared to induce the neglect of patients, and to possibly hinder the development of a personal relation between nurse and patient. This study aims to analyse whether these worries are warranted by analysing Dutch care practices using telemonitoring in care for chronic patients in the Netherlands. How do clinical practices of nursing change when telecare devices are introduced and what this means for notions and norms of good nursing? The paper concludes that at this point the practices studied do not warrant the fear of negligence and compromised relations. Quite the contrary; in the practices studied, telecare lead to more frequent and more specialised contacts between nurses and patients. The paper concludes by reflecting on the ethical implications of these changes
