Performance of Ingredients in a Soybean Whipped Topping
A liquid soybean whipped topping was developed; Illinois Soybean Beverage was used to substitute sodium caseinate as the protein source. Two-level fractional designs were shown to be efficient in systematically screening selected ingredients. Rapid cooling of the homogenized mix was the processing …

Shear and Peel Stresses at the Interface between Hollowcore Slabs and the Topping Concrete
… results in an uneven floor surface. A 50 mm topping concrete is commonly cast to level the floor surface. To avoid delamination, engineers require bonding agents to be applied on the hollowcore slab surface before pouring the topping concrete. The concrete topping can be used compositely with …

Topping The Queue: A Mixed Methods Exploration Of Principal Selection In Mississippi's Public School Districts
As a result of the competitive principal market and the varying qualities of a perfect job applicant, information is critical to job candidates, educational leadership program developers, and superintendents or members of school hiring committees. Informed by research from the fields of industry …

Vibration behaviour of pre-stressed precast hollow core floor with concrete topping thickness and boundary condition
… the low natural frequency with different topping thickness and boundary condition by the parametric study in observing its vibration behaviour pattern. The main issue in the actual design was the boundary condition between the PPHCF and l-beam, which precast is rested on l-beam without any …

Influence of cultivar, topping height, and harvest treatment on physical and chemical characteristics of flue-cured tobacco
… were compared across six cultivars and two topping heights with the objective of identifying tip grade tobacco. Agronomic and cured leaf chemistry data were collected. Cultivar had significant influences on yield, average price, grade index, and value in three growing seasons. NC 71 and RG …

Efficacy of Sucker Control Method and Effect of Topping Height on Axillary Bud Growth in Dark Fire-Cured Tobacco
The removal of terminal buds (topping) and sucker control are two practices that have an impact on yield and quality of dark tobacco (Nicotiana tabacum L.). Topping breaks apical dominance and encourages the growth of axillary buds (suckers). Following topping, growth regulator chemicals known as …

Influence of nitrogen rate, harvest frequency, lower leaf management, and chemical topping on mammoth cultivars of flue-cured tobacco
… tobacco. The feasibility of chemically topping two mammoth cultivars was also investigated. Increasing nitrogen rates increased values per hectere by $176 and total alkaloids by 0.5% in 1987. Increasing the number of harvest increased percentage lugs (X) and reducing sugars for stalk …

Effects of topping, stem density, and stage of vine cutting on canopy growth and tuber yield yield of potato (Solanum tuberosum L.)
… 1992, 1993, and 1994 to evaluate the effects of topping [(excising 2-3 cm from the terminal buds at 1 to 2 weeks after the date of plant emergence (WAE)], stage of vine cutting at ground level, and main stem density on canopy growth, tuber bulking rate, and tuber yields of potato. Topping (3 …

Influence of nitrogen fertilization and leaf management on nitrogen use efficiency and agronomic performance of mammoth cultivars of flue-cured tobacco
… to determine the effects of leaf number, time of topping, and nitrogen rate on yield, quality, and other agronomic characteristics. Nitrogen uptake, utilization, and use efficiencies decreased while nitrogen accumulation increased as nitrogen rates increased from 67 to 112 kg ha⁻¹. Mammoth …

Investigation of Concrete Mixtures to Reduce Differential Shrinkage Cracking in Composite Bridges
… thesis was to develop a concrete bridge deck topping mixture that resists the effects of differential shrinkage by decreasing shrinkage and increasing creep. . In addition, the amount of tensile creep that concrete experiences under long-term tensile stresses were quantified and compared to …

Crop manipulation to improve hybrid radish seed yield and quality : A thesis submitted in partial fulfilment of the requirements for the degree of Doctor of Philosophy at Lincoln University
… several plant growth retardants, and mechanical topping. In addition, the effect of lodging on radish seed yield was determined by mechanically supporting the crop. Lodging did not begin until after anthesis, but lodging reduced seed yield by around 21% through a reduction in all seed yield …

Systems analysis of a microfabricated storable bipropellant rocket engine
… tetroxide/hydrazine expander and decomposition topping cycles and hydrogen peroxide/ethanol and hydrogen peroxide/JP-7 decomposition topping cycles are feasible. It is shown that a 300 atm turbopump feed system is possible while further investigations on bearings and pump design are required to …

Effect of canopy manipulation and fermentation on grape aroma components
… isolation procedure. The influence of shoot topping to 10 or 20 nodes or ethephon application on grape aroma components was measured for three seasons. Canopy modification by both topping levels and ethephon treatment increased sunlight penetration into the canopy fruiting zone. Free volatile …

Factors affecting the population dynamics of the green peach aphid, Myzus persicae (Sulzer), on flue-cured tobacco in Virginia
… proportion of individuals occurring after topping of the crop. Cumulative proportional population growth models using degree-days were able to adequately describe growth of populations only on individual farms. Study of the within-plant distribution of GPA found that populations developed …

Strip-Tillage Production Systems for Tobacco
… for early season plant growth and time of topping. Starter fertilizer treatments increased tobacco root weight by 22% and leaf area up to 41%. Earlier topping was observed as a result of starter fertilizer with 23 and 6% more plants topped during the initial topping date in 1999 and 2000, …

Effect of canopy manipulation on rot incidence and rot metabolites of White Riesling (Vitis vinifera L.) grapes
… was also undertaken. The effect of shoot topping to 10 or 20 nodes or the application of ethephon on the incidence of grape rot was measured for three seasons. Canopy modification by both topping and ethephon treatment increased sunlight penetration into the fruiting zone. Fruit rot …

Nitrogen fertilization, nitrogen and nicotine content of burley tobacco
… uptake occurred during the month prior to topping. During the period prior to topping 74 percent of the total dry matter, 80 percent of the total nitrogen and 34 percent of the total nicotine accumulated in the shoots. Applying 2/3 of the 75 pounds of nitrogen per acre 21 days after …

Development of a Composite Concrete Bridge System for Short-to-Medium-Span Bridges
… T-beams finished with a cast-in-place concrete topping. The system offers enhanced performance against reflective cracking, and reduces the likelihood of cracking due to time dependent effects. The effects of transverse bending due to concentrated wheel loads are investigated with respect to …
