We introduce a theoretical framework for single-shot phase contrast imaging (PCI) measurements of spinor Bose-Einstein condensates (BECs). Our model allows for the simple calculation of the quantum backaction resulting from the measurement, and the amount of information that is read out. We find that there is an optimum time Gτ∼1/N for the light-matter interaction (G is the ac Stark shift frequency, N is the number of particles in the BEC), where the maximum amount of information can be read out from the BEC. A universal information-disturbance tradeoff law εFεG1/N2 is found where εF is the amount of backaction and εG is the estimation error. The PCI measurement can also be found to be a direct probe of the quantum fluctuations of the BEC, via the noise of the PCI signal. © 2014 American Physical Society.

The purpose of the study was to investigate the effect of interval and continuous training program on blood pressure and serum uric acid (SUA) levels in subjects with hypertension. Three hundred and fifty-seven male patients with mild to moderate systolic blood pressure (SBP) between 140 and 179 and diastolic blood pressure (DBP) between 90 and 109 mm Hg essential hypertension were age-matched and grouped into interval, continuous, and control groups. The interval (work:rest ratio of 1:1) and continuous groups were involved in an 8-week interval and continuous training program of 45-60 minutes, at intensities of 60-79% of heart rate maximum, whereas the control group remained sedentary during this period. SBP, DBP, maximum oxygen uptake (̇VO2max) and SUA concentration were assessed. One-way analysis of variance and Scheffe and Pearson correlation tests were used in data analysis. Findings of the study revealed significant effect of exercise training program on ̇VO 2max, SBP, DBP, and SUA. However, there was no significant difference between the interval and continuous groups. Changes in ̇VO2max negatively correlated with changes in SUA (r = 20.220) at p < 0.05. It was concluded that both moderate-intensity interval and continuous training programs are effective and neither seems superior to the other in the nonpharmacological management of hypertension and may prevent cardiovascular events through the downregulation of SUA in hypertension. Findings of the study support the recommendations of moderate-intensity interval and continuous training programs as adjuncts for nonpharmacological management of essential hypertension. © 2011 National Strength and Conditioning Association.

The purpose of the present study was to determine and compare the effect of interval and continuous training programs in the management of hypertension. Three hundred fifty-seven male patients with essential hypertension were age matched and grouped into interval, continuous, and control groups. The interval (n=140; 58.90±7.35 years) and continuous (n=112; 58.63±7.22 years) groups were involved in 8 weeks of interval (60%-79% maximum heart rate) and continuous (60%-79% maximum heart rate) programs of between 45 to 60 minutes, while the control group (n=105; 58.27±6.24 years) remained sedentary during this period. Findings of the study revealed significant effect of both training programs on maximum oxygen consumption, systolic blood pressure, diastolic blood pressure, heart rate, pulse pressure, and mean arterial pressure at P<.05. The maximum oxygen consumption significantly and negatively correlated with systolic blood pressure, diastolic blood pressure, rate-pressure product, pulse pressure, and mean arterial pressure at P<.01. It was concluded that both training programs are effective adjunct nonpharmacological management of hypertension. The recommendation of the paper was that both interval and continuous training programs should form part of the kit in the management of hypertension. © 2010 Wiley Periodicals, Inc..

Weight gains in pregnancy within the recommended guidelines are associated with healthy fetal and maternal outcomes; higher weight gains are associated with fetal macrosomia. This study was a systemic review of randomized controlled trials on the effect of aerobic training on maternal weight in pregnancy. The study data source was publications through May 2012 in the MEDLINE (PubMed) database. The citation lists of randomized controlled trials on the effect of aerobic training and maternal weight were extracted. Data on participants' characteristics, study quality, population, intervention, treatment outcome (maternal weight gain) were collected and analyzed. There were 11 randomized controlled studies using body weight (kg) as measure of treatment outcome. A total of 1177 subjects were recruited in the 11 studies. The mean± SD weight gain (kg) for the exercise (11.31± 7.44kg) and control (14.42± 6.60kg) groups; Meta-analysis result indicated significant effect of aerobic training on maternal weight (t= -7.580, p= .000) at p< 0.05. It was concluded that aerobic training is an effective tool in maternal weight gain control in pregnancy. More randomized controlled trials are warranted.

Hypertension remains a significant risk factor in cardiovascular morbidity and mortality. The purpose of the present study was to investigate the effects of 8 weeks interval training programme on blood pressure, aerobic capacity (VO max), indices of adiposity and marker of inflammation in black African men with essential hypertension. Two hundred and forty five (245) male subjects with stage 1 and 2 (systolic blood pressure [SBP] between 140-179 & diastolic blood pressure [DBP] between 90-109 mmHg) essential hypertension were age matched and grouped into experimental and control groups. The experimental (n=140; 58.90 ± 7.35 years) group involved in an 8 weeks interval training (60-79% HRmax) programme of between 45 and 60 minutes, while age-matched control hypertensive (n=105; 58.27±6.24 years) group remain sedentary during this period. All subjects in both groups were on antihypertensive drugs throughout the study period. Cardiovascular parameters (SBP, DBP) & VO max and percent body fat [%BF], waist to hip ratio [WHR] and C-reactive protein [CRP] were assessed. Independent t-test and Pearson correlation test were used in data analysis. Findings of the study revealed significant decreased effects of interval training programme on SBP, DBP, %BF, WHR and CRP and significant increased effect on VO max at p< 0.05. Also, changes in CRP as a result of exercise training significantly and positively correlated with changes in SBP, DBP, %BF, WHR, CRP and negatively correlated with VO max at p< 0.05.

Phytoremediation is the use of plants to extract, sequester or mineralize pollutants. This process is seen as an ecologically sound strategy for management of contaminated ecosystems. In this review, current status of several subsets of phytoremediation are discussed which includes: (a) Phytoextraction - which is a process in which high biomass pollutant accumulating plants are used to accumulate and transport pollutants from the soil to harvestable parts of plants. (b) Phytofiltration - which is a process in which plant roots are used to precipitate and concentrate pollutants from effluents. (c) Phytostabilization - here plants stabilize pollutants, thus rendering them harmless. (d) Phytovolatilization -plants absorb pollutants and convert them into gaseous components via transpiration. The advantages inherent in these technologies are also discussed. There is need for further understanding on the processes that affect pollutant availability, rhizosphere processes, pollutant uptake and sequestration. © 2010 Academic Journals.

Human immunodeficiency virus (HIV) and malaria co-infection has become an important public health problem in sub-Saharan Africa. Data on HIV and malaria interaction in Nigerian adults is scanty. We determined the prevalence of malaria parasitaemia in HIV-infected adults and further investigated the role of immune status in the HIV/malaria association. This was a cross-sectional study involving 100 newly-diagnosed HIV-infected adults and 100 age and sex-matched HIV negative controls. Malaria parasitaemia was diagnosed by blood film microscopy using Giemsa staining technique and was defined as the presence of malaria parasites irrespective of species or parasite density. HIV infection was confirmed by western blot assay and CD4 T-lymphocyte count of the HIV-infected patients was quantified by flow cytometry. The prevalence of malaria parasitaemia was higher in HIV-infected adults (24%) than in the controls (9%) (chi2 = 8.17, p = 0.04). Participants residing in rural areas had higher prevalence of malaria parasitaemia than urban dwellers both for HIV-infected patients (34.1% Vs. 16.1%, chi2 = 4.3, p = 0.04) and controls (18.4%, Vs. 6.5%, chi2 = 3.4, p = 0.04). HIV-infected male patients tended to have malaria parasitemia more than their female counterparts (33.3% Vs. 17.2%, chi2 = 3.4, p = 0.06). Among HIV-infected patients, the prevalence of malaria parasitaemia progressively increased at lower CD4 cell counts, 10.3% for CD4 cell count of = 500, 17.5% for 200-499 and 45.2% for < 200 cells/microL (chi2 = 11.5, p = 0.003). HIV is likely to fuel malaria infection in tropical countries where both diseases are endemic. Malaria control practices should be further intensified in HIV-infected populations.

As the price of chemical fertilizers in the Nigerian market continues to go high thereby making chemical fertilizers unreachable to peasant farmers and the urgent need to improve the fertility of the soils in which sweet potato (Ipomoea batatas) is grown, this investigation was carried out at Umudike, Southeastern Nigeria, to evaluate the comparative effect of Cow Dung (CD) and chemical fertilizer on soil properties, nutrient uptake and yield of sweet potato. The experiment was laid out in a randomized complete block design, with four replications. The treatments consisted of 4 t ha-1 CD, 400 t ha-1 NPK (15:15:15) fertilizer, 2 t ha-1 CD+200 kg ha-1 NPK fertilizer, 1 t ha-1 CD+300 kg ha-1 NPK fertilizer, 3 t ha-1 CD+100 kg ha-1 NPK fertilizer and control which did not receive any treatment. The result of the investigation showed that application of 3 t ha-1 CD+100 kg ha-1 NPK fertilizer improved Soil Organic Matter (SOM), available phosphorus, exchangeable cations, Effective Cation Exchange Capacity (ECEC) and base saturation more than other treatments. The treatments significantly (p = 0.05) improved nutrient uptake when compared to the control, but application of 3 t ha-1 CD+100 kg ha-1 NPK fertilizer recorded the highest values. The treatments improved the growth and yields of sweet potato more than the control with the highest tuber yield (8.91 ha-1) being produced with application of 3 t ha-1 CD + 100 kg ha-1 NPK fertilizer. Application of 3 t ha-1 CD+100 kg ha-1 NPK fertilizer is hereby recommended to farmers improvement of soil fertility and growth of sweet potato in this part of Nigeria. © 2010 Knowledgia Review, Malaysia.

This study aimed at assessing perceptions on use of ITNs in parts of the Imo River Basin, Nigeria and its implications in preventing malaria in pregnancy. Data was collected using focus group discussions, key informant interviews and structured questionnaires. Results showed high awareness on the benefits of ITNs. Factors affecting use of ITNs included its high cost, perceptions of chemicals used to treat them as having dangerous effects on pregnancy, low utilization of antenatal care, husband's lack of interest in malaria prevention and perceptions that adolescent girls are at low risk of getting malaria. The implications of these findings include demystifying the negative perceptions on the chemicals used for net treatment and subsidizing the cost of ITNs to increase access. These findings provide important lessons for malaria programmes that aim at increasing access to ITNs by pregnant women in developing countries.

The performance of hydroxypropyl methylcellulose (HPMC) as safe corrosion inhibitor for mild steel in aerated 0.5 M H2SO4 solution was appraised by weight loss, impedance and polarization measurements. Results indicate that HPMC functions as a good inhibitor in the studied environment and inhibition efficiency increased with increasing concentration of inhibitor and temperature. Time-dependent effect of the inhibition efficiency reveals that inhibition efficiency increased with time up to the fourth day after which it waned, but improved on addition of KI. The synergism parameter evaluated confirmed the synergistic effect of KI and HPMC. Impedance results clearly show that HPMC inhibited the corrosion reaction via adsorption onto the metal/solution interface following Freundlich adsorption isotherm. Polarization results indicate that HPMC acts as a mixed-type inhibitor with predominant cathodic effect. Theoretical study using density functional theory was employed to establish the correlation between the structure (molecular and electronic) and the inhibition efficiency. © 2014 Published by Elsevier Ltd.
