Abstract A 48-year-old man presented for evaluation of an expanding abdominal mass. Twenty years earlier, he had developed Fournier’s gangrene requiring extensive debridement. He underwent augmentation cystoplasty with a catheterizable stoma due to a proximal urethral stricture. Fifteen years later, he was found to have a 14 cm x 18 cm bladder augment calculus. Simpson obstetric forceps were passed into the augment to deliver a 1110 gram stone with minimal devitalization of the colonic augmentation tissue. This is the first report of stone management with obstetric forceps in an augmented bladder. The specimen itself is among More >

Abstract The objective of this study is to investigated thermal diffusion and radiation effects on unsteady free convection chemically reacting fluid flow past an accelerated infinite inclined plate with variable temperature and mass diffusion under the influence of uniform transverse magnetic field when the magnetic lines of force are fixed relative to the fluid or to the plate studied in two cases, (i) when magnetic field fixed relative to the fluid (K=0), (ii) and the magnetic field fixed relative to the plate (K=1) have been considered. A general exact solution of the dimensionless governing partial differential equation More >

Abstract In this paper, we investigated the influence of melting on mixed convection heat and mass transfer from the vertical flat plate in a non-Newtonian nanofluid saturated porous medium. The wall and the ambient medium are maintained at constant, but different, levels of temperature and concentration. The Ostwald–de Waele power-law model is used to characterize the non-Newtonian nanofluid behavior. A similarity solution for the transformed governing equations is obtained. The numerical computation is carried out for various values of the non-dimensional physical parameters. The variation of temperature, concentration, heat and mass transfer coefficients with the power-law More >

Abstract Spatial expansion of clonal plants and growth of their modules are of concern in the field of plant ecology. After measuring a large number of samples, we analyzed the module components and the growth patterns of vegetatively propagated Agropyron michnoi clones in the Songnen Plain on Northeast China. The results showed that the plasticity of clonal growth was large; the coefficients of variation of both extensive areas and the quantitative characters of modules were more than 20%. The numbers of ramets, seedlings, and buds and the cumulative length of the rhizomes showed exponentially and linearly increasing More >

Abstract In the production of cotton (Gossypium hirsutum L.), nitrogen fertilization is one of the most costly crop practices, but important to reach high yields. However, high nitrogen (N) content in plants does not always translate into a high fibre production. One way of assessing the efficiency of the N fertilizer is through the enzymatic activity of the nitrate reductase (NR). This is a key enzyme in N assimilation, whose activity is regulated by a number of endogenous and exogenous factors that determine yield. The aim of this study was to assess the effect of N fertilization… More >

Abstract Proteins are one of the major metabolites in biomass from microalgae that constitute the diet of marine organisms grown in aquaculture, and are essential for their growth. The quantity of this component is influenced by nutrients, temperature and light intensity, among others. We examined the growth, biomass production and protein of Chaetoceros muelleri with two sources of nitrogen (nitrate and urea) at three concentrations, using the medium f/2 (0.88 mol/L) (nitrates) as control. The treatments were the medium 2f (3.53 mol/L) and 4f (7.05 mol/L) with NO_3^-, and the medium f/2 (0.88 mol/L), 2f (3.53mol/L) and 4f More >

Abstract The effect of six phosphorus levels (0, 40, 80, 120, 160 and 200 kg/ha) on the duration of cumulative leaf area, biomass and agronomic yield was determined in the maize cultivars: Amarillo Almoloya, Cacahuacintle and Condor in 2010 and 2011. Such cultivars were sown in the Cerrillo Piedras Blancas Mexico. A completely randomized complete block design with factorial arrangement was utilized. High phosphorus levels (120, 160 and 200 kg/ha) positively affected the duration of cumulative leaf area; greatest values were obtained in Cacahuacintle. A greater duration of accumulated leaf area contributes to determine high values More >

Abstract A regression model was used to determine the relationship between aerial herbaceous biomass and vegetation coverage estimated by digital images. Four samplings (n=36 each date) of vegetation cover and herbaceous biomass were performed during the growing season in 2011 in a grassland dominated by Bouteloua gracilis in La Cieneguilla, Municipality of Villa Hidalgo, Durango. Average production of dry biomass was 37.36 ± 9.66 g/m², and mean vegetation cover 30.02%. Dry biomass data were tested for normality using the test of Kolmogorov Smirnov, finding a lack of fit. The data were subjected to a logarithmic transformation and the… More >

Abstract Pecan [Carya illinoensis (Wanngenh) K. Koch] is one of the most important nut crops in arid and semiarid regions of Mexico. Here, most pecans are grown in saline soils having poor permeability which are further degraded by the use of low-quality irrigation water. Salinity adversely affects both pecan nut quality and yield. Little work has been done to explore the physiological effects of salinity on native pecan trees. Here we examine physiological changes determined by exposure of pecan seedlings to sodium sulfate (Na₂SO₄) at four concentrations: 1000, 2000, 3000 and 4000 mg/L applied twice weekly over a… More >

Abstract A 67-year-old male patient presented with right scrotal swelling and underwent a right hydrocelectomy. A 1 cm paratesticular lesion was found within the hydrocele sac after entering the tunica vaginalis. Local excision grossly removed this in its entirety. Pathology returned as well differentiated papillary mesothelioma of the tunica vaginalis. Pathologic features and management options are discussed. More >
