The Demise of the Congress for Cultural Freedom: Transatlantic Intellectual Consensus and "Vital Center" Liberalism, 1950-1967

From the 1950 to 1967, the U.S. government, employing the newly formed CIA, covertly provided the majority of the funding for an international organization comprised primarily of Western non-communist left intellectuals known as the Congress for Cultural Freedom. The Paris-based Congress saw its primary mission as facilitating cooperative networks of non-communist left intellectuals in order to sway the intelligentsia of Western Europe away from its lingering fascination with communism. This thesis explores how the Congress largely succeeded in the 1950s in establishing a cohesive international network of intellectuals by fostering a transatlantic consensus around "vital center" liberalism as a necessary guardian of the Western cultural intellectual tradition in the face of perceived communist threats. By examining the ways in which developments in the 1960s shattered this transatlantic consensus this thesis demonstrates how the Congress suffered an inevitable demise as Western intellectuals became disillusioned with American liberalism of the "vital center.

Statistical Modelling of Drying Characteristics of Unripe Plantain (Musa Paradisiaca) Slices

This work is designed to carry out the statistical modelling of the drying characteristics of unripe plantain (Musa paradisiaca) slices and to study the effect of drying temperature and slice thickness on drying characteristics. The test samples were dried in a laboratory scale oven dryer at varying temperatures of 700C, 800C and 900C, and different slice thicknesses of 2mm, 3mm and 4mm.The result obtained indicated that drying temperature and slice thickness had significant effect on drying rate and hence moisture profile. The moisture ratio – drying time data obtained were fitted to ten thin layer drying models. The fit quality obtained with each model was evaluated using statistical tests namely; coefficient of determination (R2), root mean square error (RMSE), reduced chi-square (X2), and standard error of estimate (SEE). Although most of the models fitted quite well to the experimental data, Page and Modified Page models showed the highest average R2 and the lowest average RMSE, X2 and SEE values. Page and modified Page models were selected and found suitable to represent the drying characteristics of unripe plantain slices and predict drying times

Effect of Vitamin D on serum markers of bone turnover in SLE in a randomised controlled trial

© 2019 Author(s). Objective Bone health in SLE is adversely affected by vitamin D deficiency, inflammatory cytokines and glucocorticoid use. We hypothesised that vitamin D supplementation would increase markers of bone formation and decrease markers of bone resorption in SLE subjects. Methods We studied 43 vitamin D-deficient SLE subjects who participated in a 12-week randomised controlled trial of 2000-4000 IU/day vitamin D supplementation versus placebo. Subjects had inactive SLE (SLE Disease Activity Index ≤4) and were taking D, N-terminal propeptide of type 1 collagen (P1NP) and C-telopeptide (CTX). We tested the effect of vitamin D versus placebo on change (δ) in P1NP and δCTX in an intention-to-treat analysis. Secondary analyses evaluated whether vitamin D affected bone turnover among subjects achieving vitamin D repletion (≥30 ng/mL) or currently taking glucocorticoids. Results 28 subjects were randomised to vitamin D and 15 to placebo. Mean age was 39 years and 40% were using glucocorticoids at enrolment. Repletion was achieved by 46% in the vitamin D group versus none in the placebo group. Changes in bone turnover markers were not significantly different in the vitamin D group versus placebo group (median δP1NP -0.2 vitamin D group vs -1.1 placebo group (p=0.83); median δCTX +3.5 vitamin D group vs -37.0 placebo group (p=0.50)). The effect of vitamin D did not differ based on achieving vitamin D repletion or baseline glucocorticoid use. Conclusion Vitamin D supplementation did not affect the 12-week change in bone turnover markers among SLE subjects in this trial

Phase curves of WASP-33b and HD 149026b and a New Correlation Between Phase Curve Offset and Irradiation Temperature

We present new 3.6 and 4.5 $\mu m$ Spitzer phase curves for the highly irradiated hot Jupiter WASP-33b and the unusually dense Saturn-mass planet HD 149026b. As part of this analysis, we develop a new variant of pixel level decorrelation that is effective at removing intrapixel sensitivity variations for long observations (>10 hours) where the position of the star can vary by a significant fraction of a pixel. Using this algorithm, we measure eclipse depths, phase amplitudes, and phase offsets for both planets at 3.6 $\mu m$ and 4.5 $\mu m$. We use a simple toy model to show that WASP-33b's phase offset, albedo, and heat recirculation efficiency are largely similar to those of other hot Jupiters despite its very high irradiation. On the other hand, our fits for HD 149026b prefer a very high albedo and an unusually high recirculation efficiency. We also compare our results to predictions from general circulation models, and find that while neither are a good match to the data, the discrepancies for HD 149026b are especially large. We speculate that this may be related to its high bulk metallicity, which could lead to enhanced atmospheric opacities and the formation of reflective cloud layers in localized regions of the atmosphere. We then place these two planets in a broader context by exploring relationships between the temperatures, albedos, heat transport efficiencies, and phase offsets of all planets with published thermal phase curves. We find a striking relationship between phase offset and irradiation temperature--the former drops with increasing temperature until around 3400 K, and rises thereafter. Although some aspects of this trend are mirrored in the circulation models, there are notable differences that provide important clues for future modeling efforts

Modelling the Dynamics of a Hypereutrophication Process in Ruguma Ponds in Rumuosi-Akpor, Nigeria

In this work, Experimental results were monitored for a period of eight months on certain variables parameter in great Ruguma eutrophication site with Fugro International Laboratory to observe the profiles of the simultaneous variations of these parameters with time. Some parameters show the approach or eminence of hypereutrophication. Cox et al (2009) model for recovering from hypereutrophication was modified to accommodate phosphate concentration variation in the great Ruguma hypereutrophication. Numerical values of constraints, initial and boundary conditions were culled in from the works of Cox et al (2009) in solving the system of ODEs modified.From the analysis made on the results obtained, the Great Ruguma Seasonal Ponds may be said to be recovering from hypereutrophication.The findings of this work can be applied in any trophic study especially when it is entering or recovering from hypereutrophication

Curve-Fitting of Bioremediation of Polycyclic Aromatic Hydrocarbons (PAHs) By Co-Composting Using Roost Manure

In this work, ten polluted sites with oil were obtained from Niger Delta, mixed homogenously with compost manure and sent to FUGRO International Laboratory PortHarcourt Nigeria, for bioremediation experiments and analyses. The 4800g sample was divided into twelve (12) equal parts of 400g for bioremediation; 6 parts for the experiments and 6 parts for the control. Particular ringed PAH was isolatedly tested for bioremediation for each of the five ringed PAHs (1 to 5 rings) and the 800g sample was used for respiration test of compost incubation. It was found that the efficiency of bioremediation increased from one to three rings and decreased exponentially for the rest of the rings, showing that bioremediation is not effective for higher ring PAHs. It was also found that bioremediation yields best (optimum) result between two and three ringed PAHs. The respiration of the compost microorganisms improved during incubation by more than two-third i.e 67.7%. The result of this work can be used in bioremediation studies when trying to isolate or choose a particular ringed PAHs for such bioremediation job

Water Quality Impact of Flow Station Effluent in a Receiving Creek

The physicochemical quality of a crude oil flow station effluent and water of an effluent receiving creek were investigated. Samples were characterized by laboratory analysis. High concentrations of some toxicants exceeding environmental standards were observed in the effluent and water samples, which include BOD5 (544mg/L), COD (650mg/L), salinity (3162mg/L), copper (2.3mg/L), TDS (18900 mg/L), lead (0.51mg/L), and cadmium (0.04mg/L). The study underscored the need for proper treatment and monitoring of effluent to ensure compliance with statutory standard, before discharge into the environment to safeguard the ecosystem, as continued discharge of improperly treated effluent may compound the ecological problem of the receiving water environmen

Cigarette smoking disparities among sexual minority cancer survivors

AbstractObjectiveSexual minority (i.e., lesbian, gay, and bisexual) adults smoke cigarettes at higher rates than heterosexual adults. Smoking after receiving a cancer diagnosis is a major health concern, yet risk of continued smoking among sexual minority cancer survivors is as yet unknown. The current study examines current smoking among sexual minority vs. heterosexual adult cancer survivors.MethodData drawn from the 2010 Behavioral Risk Factor Surveillance System survey in five states (Alaska, California, Massachusetts, New Mexico, and Wisconsin) included items about sexual orientation, cancer diagnosis, and tobacco use. The analytic sample included 124 sexual minority and 248 propensity score matched heterosexual adult cancer survivors.ResultsBivariate analysis showed that sexual minority cancer survivors had twice the odds of current smoking as their heterosexual counterparts (OR=2.03, 95%CI:1.09–3.80). In exploratory analyses stratified by sex, sexual minority disparities in prevalence of smoking post-cancer showed a trend toward significance among females, not males.ConclusionThe current study offers preliminary evidence that sexual minority status is one variable among many that must be taken into account when assessing health behaviors post-cancer diagnosis. Future research should identify mechanisms leading from sexual minority status to increased rates of smoking and develop tailored smoking cessation interventions
