Bread spread is one of the fundamental foods in human diets. Generally, cheese spread, butter, chocolate spread, and margarine are the most consumed. In the last decade, a new concept alimentary has been integrated, it was low fat spread or functional spread. This work is an attempt to formulate and optimize new low-fat spreads based on olive oil and honey using a response surface methodology box-benken design. To optimize its stability and its textural properties under the effects of three factors, beeswax content, stirring time, and stirring speed. Results revealed that the best mixture was the formulation that contained 1% beeswax, 79% honey, and 20% olive oil, formulated under 6.39 min of time stirring at 15,428 rpm speed. The beeswax was the major factor showing the highest effect on all the properties of spreads.

Numerical investigation of velocity ratio effect in combined wall and offset jet flows

引用

Journal of Hydrodynamics 2018年第6期30卷 1105-1119页

作者： Nidhal Hnaien salwa Marzouk Habib Ben Aissia Jacques Jay Unité de Métrologie et des systèmes énergétiques Ecole National d'ingénieurs de Monastir Tunisie Centre de Thermique de Lyon (CETHIL-UMR CNRS 5008) INSA de Lyon France

In the present work, we propose to numerically study a combined turbulent wall and offset jet flow(this combination will be denoted WOJ). Several turbulence models were tested in this study: the standard k-w, SST k-w, standard k-ε, RNG, and realizable k-ε model. A parametric study was performed to determine the effect of offset ratio H and the velocity ratio r on the longitudinal and transverse positions of the merge point(MP), the combined point(CP), the upper vortex center(UVC) and the lower vortex center(LVC). Correlations that predict the position of these characteristic points of the WOJ flow as a function of H and r have been provided. Results show that any increase in the velocity ratio causes a displacement of the MP, CP, UVC and LVC further upstream along the longitudinal direction. Concerning the transverse positions, the increase of velocity ratio results in a deviation of the merge point(MP) and the lower vortex center(LVC) toward the strong jet(LWJ) whereas the transverse position of combined point(CP) and the upper vortex center(UVC) is almost independent of the velocity ratio.

Indolent lung opacity: Ten years follow-up of pulmonary inflammatory pseudo-tumor

World Journal of Clinical Cases 2017年第2期5卷 61-66页

作者： Jad A Degheili Nadim A Kanj salwa A Koubaissi Mouhamad J Nasser Division of General Surgery Department of Surgery American University of Beirut-Medical Center Division of Pulmonary Critical Care and Sleep Medicine Department of Internal Medicine American University of Beirut-Medical Center Department of Internal Medicine American University of Beirut-Medical Center

Inflammatory pseudotumor(IPT) has always been considered a diagnostic challenge. Its rarity and resemblance to other more common pathological entities imposes that neither clinical nor radiological characteristics can lead to a definitive diagnosis. The surgical excision of the lesion is the ultimate approach for accurate diagnosis and cure. Moreover the true nature of IPT, its origin as a neoplastic entity or an overreactive inflammatory reaction to an unknown trigger, has been a long debated matter. Surgery remains the treatment of choice. IPT is mostly an indolent disease with minimal morbidity and mortality. Local invasion and metastasis predict a poor prognosis. We hereby present a unique case of pulmonary IPT that was surgically excised, but recurred contralaterally, shortly thereafter. Despite no medical or surgical treatment for ten years, the lesion has remained stable in size, with neither symptoms nor extra-pulmonary manifestations.

There are three major challenges for climatic data availability for Reference Evapotranspiration (ET0) calculations in Bosnia and Herzegovina:limited data availability,discontinuity of data records,and low station *** main objective of this study was to apply reliable methods to calculate and spatially distribute ET0,while considering the impact of the elevation.A 20 m spatial resolution map was created for mean ET0 values at monthly,vegetation period (April-September) and annual temporal resolution at municipality (143 municipalities),regional (4 regions) and national spatial resolutions.108 weather stations for the period 1961-2016 (56 years) were utilized for spatial interpolation of ET0 using kriging with external drift *** required elevation for ET0 estimation at each grid node was ext'acted from the digital elevation model of Bosnia and ***0 was calculated using FAO-56 PenmanMonteith,and in cases where only minimum and maximum temperature data were available the Hargreaves-Samani equation adjusted with locally appropriate empirical radiation coefficient was used.A gradual decrease of mean ET0 values from the southern to central and northern to central part of the country is *** the all seasons (monthly,vegetation and annually),the southern region has greater ET0 than the other three regions (north,west and central-east),which are *** long-term mean annual ET0 for Bosnia and Herzegovina is 716 mm,approximately 78% (559 mm) of which occurs during in the vegetation period.
