Complicating Social Order in the Rural Areas of Akwa Ibom State Nigeria

In a typical traditional society in Nigeria laws, rules, norms, and taboos were used by community elders to enforce social order and curtail practices, behaviours, values and beliefs that were counter to the stability of the social structure. However, the contemporary rural communities have witnessed a shift within the social structures and institutions, in behaviours, cultural aspects which affect social relations, social interaction and the maintenance of the status quo by the traditional rulers. This qualitative study examined the roles of traditional rulers in complicating social order in Ikot Annang and Ikot Abasi communities in Akwa Ibom State, South-South Nigeria. In-depth interviews and participant observation were used to collect data on the subject under study. Ethnomethodology by Garfinkel was adopted as theoretical guide for the study. Findings of the study show that betrayal of community interest, mismanagement of community generated revenue, neglect of traditions, abuses of traditional power by some community elders, and youth groups are contributing to upheaval in some rural communities in Akwa Ibom State. Researchers concluded that the decisions by some of the rural community elders and youth groups to adopt western customs over their traditional customs have distorted the state of stability and consensus that existed in the traditional rural areas, thereby bringing about a shift that disrupts social order. Among other, the researchers recommended the need for culture check and rite of passage for youth groups in line with customs and traditions

Aerosols loading statistical dimensions over Serekunda-Gambia

Aerosols loading and retention justifies the efficiency of the 'self-cleansing' mechanism of the geographical air space. The advantage of the proposed technique which is based on the coefficient of variation helps to estimate the aerosols retention over a geographical area without necessarily going through the complexities of formulating sectional equations to illustrate the physics of the atmosphere. The system of aerosol retention over Serekunda suggests that air pollution should be taken more seriously to avoid natural disasters in the nearest future. It was discovered that the 'self-cleansing' cycle over Serekunda is four years. The year with a fairly high aerosols retention and correlation was between 2006 & 2007 i.e. 36.82 and 0.61 respectively

Molecular Model of the Contractile Ring

We present a model for the actin contractile ring of adherent animal cells. The model suggests that the actin concentration within the ring and consequently the power that the ring exerts both increase during contraction. We demonstrate the crucial role of actin polymerization and depolymerization throughout cytokinesis, and the dominance of viscous dissipation in the dynamics. The physical origin of two phases in cytokinesis dynamics ("biphasic cytokinesis") follows from a limitation on the actin density. The model is consistent with a wide range of measurements of the midzone of dividing animal cells.Comment: PACS numbers: 87.16.Ka, 87.16.Ac http://www.ncbi.nlm.nih.gov/pubmed/16197254 http://www.weizmann.ac.il/complex/tlusty/papers/PhysRevLett2005.pd

ANALYSIS OF PUBLIC AND PRIVATE - SECTORS PARTNERSHIP (PPP) IN HOUSING DELIVERY IN, NIGER STATE. NIGERIA

Abstract: One of the greatest challenge confronting both rural and urban residents in Niger State is the need to provide adequate shelter. This study examined the individual significant contribution of the public and private sector in public-private partnerships (PPP) in housing contracts in Niger State, Nigeria. The study review that PPP has so far achieved little success in providing decent and unaffordable housing accommodation to Nigerlites. Accordingly to Niger State housing corporation 2 bedrooms flat worth N3,500,000.00 and 3 bedrooms flat worth N4,500,000.00 so it’s clear that the houses are unaffordable to low and medium incomes earners. The researcher finding that the private sector in Niger State can be said to have contributed very little to the development of an urban project in the state, however, even this insignificant level of participation has been serious challenges by poor funding and lack of policy framework to regulate it activities. Therefore, it is paramount importance that the state should develop a regulatory framework and partner with the private sector in this regard so as to ensure that the resident of Niger State has access to this important component of the human environment. Researcher concluded that to ensure the effective participation of the private sector in housing delivery in Niger State in general and Minna in particular, the following recommendation has been put forward (1) Aside from providing enabling environment for the private sector to develop real estate, government should also invest more in provision of site and services scheme this will hasten the development of estate sector.  (2) The establishment a power federal mortgage bank (FMB) and  urban development bank would guarantee investors access to loan and other facilities needed for mass housing development.(3) strengthening the activities of the Niger State Ministry of land and housing in order to ensure that both the formal and informal neighborhood save provided with sanction and neighborhood facilities and (4) The establishment of a PPP steering committee in the Niger State that would be responsible for the general oversight of state’s PPP arrangement. (5) Finally, the study recommends that to ensure the success of public and private partnership in housing delivering, all tiers of government must strive to complement the weakness of the public sector with the strength of the private sector.

Nutrient requirements for the growth of waterleaf (Talinum triangulare) in Uyo metropolis, Nigeria

The all-season vegetable known as waterleaf (Talinum triangulare) is extensively grown in Nigeria’s metropolistan market gardens. This paper examines the soil compositions of some of the cultivation areas for this crop to determine the impacts of its very intensive repetitive cultivation. In general, the regular application of organic manures and mineral fertilizers has maintained the fertility status of the market garden soils. Multiple regression analysis indicated that base saturation, available phosphorus and organic matter were the most significant determinants to variations in crop production

Commissioning of the electron injector for the AWAKE experiment

The advanced wakefield experiment (AWAKE) at CERN is the first proton beam-driven plasma wakefield acceleration experiment. The main goal of AWAKE RUN 1 was to demonstrate seeded self-modulation (SSM) of the proton beam and electron witness beam acceleration in the plasma wakefield. For the AWAKE experiment, a 10-meter-long Rubidium-vapor cell together with a high-power laser for ionization was used to generate the plasma. The plasma wakefield is driven by a 400 GeV/c proton beam extracted from the super proton synchrotron (SPS), which undergoes a seeded self-modulation process in the plasma. The electron witness beam used to probe the wakefields is generated from an S-band RF photo-cathode gun and then accelerated by a booster structure up to energies between 16 and 20 MeV. The first run of the AWAKE experiment revealed that the maximum energy gain after the plasma cell is 2 GeV, and the SSM mechanism of the proton beam was verified. In this paper, we will present the details of the AWAKE electron injector. A comparison of the measured electron beam parameters, such as beam size, energy, and normalized emittance, with the simulation results was performed

Echolucency of carotid plaques correlates with plaque cellularity

AbstractObjective: to analyse the relationship between carotid plaque echolucency and cellularity. Methods: carotid plaques (14 symptomatic and 16 asymptomatic) were snap frozen after endarterectomy and defined on the basis of their grey-scale-median (GSM), obtained from pre-operative high-definition ultrasonography, as either echolucent (<32) or echogenic (≥32). DNA and total soluble protein were determined to assess cellularity. Results: after correcting for wet weight, symptomatic plaques had significantly more DNA (0.400 ± 0.07 vs 0.335 ± 0.07 mg/g; p = 0.03) and soluble protein (34.1 ± 6.6 vs 29.7 ± 3.4 mg/g; p = 0.03) than asymptomatic plaques. Predominantly echolucent (Grey-Weale classification) plaques had more DNA (0.404 ± 0.06 vs 0.332 ± 0.08 mg/g; p = 0.03) than echogenic plaques. Plaques with GSM < 32 also had more DNA (0.386 ± 0.08 vs 0.319 ± 0.06 mg/g; p = 0.04) and soluble protein (34.7 ± 7.3 vs 29.6 ± 4.2 mg/g; p = 0.03) than those with GSM ≥ 32. Inverse relations were found between GSM and plaque DNA (r = −0.47; p = 0.02) and soluble protein (r = −0.45; p = 0.02) as well as between age and DNA (r = 0.39; p = 0.04) and soluble protein (r = −0.50; p = 0.003). Conclusions: echolucency of carotid plaques as assessed by ultrasonography reflects plaque cellularity. This observation support the notion that ultrasonography can be used to identify high-risk plaques and evaluate effect of interventions on plaque structure.Eur J Vasc Endovasc Surg 26, 32-38 (2003
