Colour Consciousness and Design in Blanche Fury as Technicolor Melodrama

This article addresses colour and music as elements associated with the rhetoric and excesses of film melodrama through a case study of Blanche Fury (1947). Music is discussed as an analogy for thinking about colour composition and the moving image through the rhetoric and practices of Technicolor design and a theoretical context contemporary to the film’s making discerned in both production materials and film text. Colour takes on a musical value which serves a diegetic function by both situating characters in relation to the mise-en-scène and operating as a cue to instances of perception attributed specifically to the female protagonist. Drawing on theories of melodrama and colour I will argue that colour and music are integral to and offer material for further explorations of feminine desire and sexual difference as they can be seen to operate in this particular melodrama

Impact of Maternal Helicobacter pylori Infection on Trace Elements (Copper, Iron and Zinc) and Pregnancy Outcomes

Background: H. pylori infection has been suggested to interfere with micronutrient metabolism and influence pregnancy outcomes. Objectives: This study therefore seeks to document the prevalence of H. pylori seroposivity among pregnant women and to determine its impact on some trace element status and pregnancy outcomes. Materials and methods: Three hundred and forty nine consenting pregnant women aged 15-40 years (mean; 27. 04 ± 4. 75 years) and gestational age ≤ 25 weeks (mean 21.77 ± 3.14 wks) attending antenatal clinic at Federal Medical Centre, Abakaliki, between July 2007 and September 2008 participated in the study. H. Pylori antibody (IgG) was determined by a new generation ELISA method. Plasma copper, iron and zinc were analysed using flame atomic absorption spectrophotometer (Bulk Scientific AVG 210 Model) while haemoglobin and albumin were analysed using standard haematological and biochemical techniques. Both maternal sociodemographic and anthropometric parameters were recorded at recruitment. The women were followed-up till delivery after which neonatal anthropometrics and other birth outcomes were recorded. Results: H. pylori seroprevalence of 24.1% (84/349) was recorded with higher prevalence in multiparous and older women. H. pylori infected women had significantly higher BMI (29.00 ± 3.89 vs. 26.86 ± 4.10, p = 0.020) and lower (p > 0.05) plasma levels of Cu, Fe, Zn, albumin, and haemoglobin when compared to non-infected women. Also H. pylori infected women had significantly (p < 0.05) higher rates of convulsion and concomitant illnesses than their non-infected counterparts, although there was no difference in the two groups for other pregnancy outcomes. Conclusion: H. pylori infection during pregnancy seems to interfere with trace element metabolism and contribute significantly to increased maternal morbidity. Prior to confirmation of these findings in a well controlled randomised trial, it is suggested that pregnant women be screened for H. pylori infection to reduce H. pylori associated morbidities during pregnancy

Transition to sub-Planck structures through the superposition of q-oscillator stationary states

We investigate the superposition of four different quantum states based on the q-oscillator. These quantum states are expressed by means of Rogers-Szego polynomials. We show that such a superposition has the properties of the quantum harmonic oscillator when q -> 1, and those of a compass state with the appearance of chessboard-type interference patterns when q -> 0

The magic of the Last Planner® System for Nigerian construction

Extremely poor economic performance of the Nigerian construction industry suggests that non-value adding activities are prevalent, which result not only in the reduction of contractors’ profit margin but economic loss for the country in general. This study analyses non-value adding activities in Nigerian construction sites. The research seeks to establish potential antidotes within the Last Planner® System (LPS) and reveal the elements of the LPS which could be abstracted into Nigerian construction to improve performance. It was found that these elements form the theoretical basis for developing a lean approach that was labelled Last Planner® thinking

A Comparative Study of Plasma Trace Elements (Copper, Iron and Zinc) Status in Anaemic and Non-anaemic Pregnant Women in Abakaliki, Nigeria

For a comparative study of plasma copper, iron and zinc between anaemic and non-anaemic pregnant women, data for anaemic (n = 223) and non-anaemic (n = 126) pregnant women drawn from a cohort of 351 pregnant Nigerians recruited at gestational age of ≤ 25 weeks for the study of impacts of trace element status on pregnancy outcomes were analysed. With the exception of plasma copper which was significantly (p < 0.05) higher in anaemic women in comparison to the non-anaemic women (10.11 ± 10.15 vs. 8.68 ± 7.92 µmol/l), plasma iron and zinc were lower (p > 0.05) in the former. While plasma copper, iron and zinc concentration were not correlated with maternal haemoglobin concentration, plasma zinc significantly correlated negatively (r = -0.141, p < 0.05) with plasma copper. It is thus concluded that anaemia in pregnant women in this population may partly be due to a combination of trace element deficiencies and their interactions with each other. While interventions should go beyond improving intakes, more research is desired to clearly define these interactions
