ues that introduce ±2.5% error in the estimated WED for subjects of 20-cm and 30-cm WED. CONCLUSIONS The stability in calibration results among CT scanners of the same vendor and over time demonstrated the feasibility of implementing WED estimation for routine clinical use.

Particularly, understanding foraging fidelity (i.e., returns to a particular plant species or area) is crucial for providing supportive habitats. Numerous approaches have been used to discern the movement and foraging of individual bees (reviewed by Mola & Williams 2019), ranging from highly technological to more traditional methods like mark-release-recapture experiments. While mark-recapture experiments are often hampered by low recapture rates, density dependence, and logistical constraints (Mola and Williams 2019), they can help us understand short-term local movement patterns (Dorchin et al. 2013) and fidelity (Ogilvie and Thomson 2016) of highly mobile organisms like bees.

The measurements of sample behavior for water-based formulations above 100°C is extremely challenging due to changes in material composition from the boiling of volatile ingredients. We have developed a high-sensitivity, pressurized starch pasting cell (up to 5 bar) which utilizes a design free of mechanical bearings and seals, resulting in an order-of-magnitude improvement in torque sensitivity (1 μN.m in oscillatory and 10 μN.m in shear flows) compared to traditional pressure cells. A pressurized atmosphere in the cell suppresses boiling of the volatile components, allowing the characterization of the structure-property relationships of the sample over a range of testing conditions (-5 to 150°C) which simulate industrial processing and storage conditions. This cell is employed to investigate the pasting properties of a commercial starch dispersed in water. In situ gelatinization of resses range from 0.25 to 6.5 Pa for ϕ between 0.05 and 0.15, with 0.05 being the minimum starch weight fraction for which there is any measurable yield stress. The yield stress and the paste viscosity both scale with starch particle weight fraction as (ϕ - ϕc ) m , where ϕc = 0.04 as no yield stress is observed for ϕ ≤ 0.04. The exponent, m, for yield stress is found to be in the range of 1.15-1.4 depending on the analytical method used and the definition of yield stress while for peak and breakdown viscosities it is noted to be 1.6 and 1.1, respectively. The Herschel-Bulkley model is found to fit the flow curves well. The starch pastes are found to exhibit shear-thinning and significant thixotropic behavior. © 2020 Wiley Periodicals, Inc.OBJECTIVE To characterize human papillomavirus (HPV) prevalence and distribution among female university students in Maputo, Mozambique, and evaluate the determinants of HPV infection. METHODS A cross-sectional study among 504 female university students between February and April 2017. Cervicovaginal self-collected samples were analyzed for HPV genotypes by polymerase chain reaction-restriction fragment length polymorphism and AnyplexTM II HPV28 Detection kit (Seegene®). selleck chemical RESULTS The prevalence of any HPV genotype was 28.6% (144/504). Single and multiple HPV infections were detected in 76 (15.1%) and 68 (13.5%) participants, respectively. Prevalence of high-risk HPV was significantly higher than that of low-risk HPV (P less then 0.001). HPV16 was the most frequent genotype, followed by HPV58, HPV66, HPV52, HPV18, HPV56, HPV61, and HPV70. The prevalence of genotypes covered by the bivalent, quadrivalent, and nonavalent vaccine was 14.3%, 15.9%, and 23.4%, respectively. Number of sexual partners over lifetime and in the past 12 months was associated with HPV infection (P less then 0.001 and P=0.039, respectively). CONCLUSIONS Knowledge of HPV genotype-specific prevalence among young women is important to set up strategies for HPV vaccination. The findings suggest that introduction of the nonavalent HPV vaccine might be the way forward in the present low-resource setting. In addition, self-sampling was useful for HPV detection and genotyping. This article is protected by copyright.

This study describes the root, rhizome and aerial stem xylem anatomy and functional anatomy of Canna indica, Cyperus papyrus and Phragmites communis grown on flooded substrates; and it aims to evaluate the relationship between the xylem anatomy and its cavitation resistance. To calculate the indexes of vulnerability, mesomorphy, collapse and relative hydraulic conductivity in the three organs mentioned, the diameter, number of vessels per mm2 , thickness of the walls and the length of the tracheal elements were recorded. In addition, the xylem specific conductivity of the aerial stem was measured with the pipette method, and its resistance to cavitation was determined experimentally by the air injection technique. The protoxylem is xeromorphic, it has longer vessel elements, smaller diameters, thin walls and scalariform perforation plates, whereas the metaxylem is mesomorphic, with shorter vessel elements, larger diameters, thicker walls and simple perforation plates. Both present low collapse resistance but have a high relative hydraulic conductivity. P. communis recorded the highest cavitation resistance, and the number of vessels per mm2 was related to xylem cavitation resistance in Canna indica and Cyperus papyrus. The experimental results of this investigation match partially the anatomical indexes and showed that the xylem of these species has a low specific conductivity and is more vulnerable to cavitation than that of other monocots. © 2020 Scandinavian Plant Physiology Society.
