The Pedagogic Capacity of Architecture the Macro Project University Citadel—University of Atlántico Barranquilla—Colombia  [PDF]
Carlos Bell Lemus, Mayra Alejandra Rivero Bueno
Open Journal of Civil Engineering (OJCE) , 2018, DOI: 10.4236/ojce.2018.82011
Abstract: Urban agenda nowadays puts pedestrians as the axis of urban design, and pedestrians are the most important thing in the city. The architect takes that idea and applies it in the project, and he focuses on prioritizing the pedestrian over the cars. Public spaces filled with green zones are a main element, water treatment is a design determinant, buildings use natural illumination as much as possible and culture and arts are reinforced through new scenarios.
Industria, puerto, ciudad (1870-1964): Configuración de Barranquilla
Bell-Lemus,Carlos;
Apuntes: Revista de Estudios sobre Patrimonio Cultural - Journal of Cultural Heritage Studies , 2008,
Abstract: the emergence of barranquilla as colombia's most important maritime and fluvial port at the beginning of the 20th century was the result of the need for connecting the young republic to global markets. this process took place throughout the second half of the 19th century and was consolidated with bocas de ceniza 's breakwater construction and ended with the strengthening and supremacy of buenaventura's port, which became connected to the main export destination when the panama channel was completed. during this evolution process, colombian government protectionist policies, barranquilla's comparative advantages due to its geographic location, its cultural genesis and the weaknesses of other transportation modes at the beginning of the 20th century defined the conditions for the city's emergence in terms of modern industrial adaptation, capitalist rationale and the notion of "progress". barranquilla's industrialization process left some interesting physical evidence that represents the efforts, attempts and paradigms that emerged from the architectural and urban discourse of the period in which modern industrialization was materialized in the city.
Long-Term Summary of Ryegrass Varieties and Ploidy Types in Mississippi  [PDF]
Joshua A. White, Rocky Lemus
American Journal of Plant Sciences (AJPS) , 2014, DOI: 10.4236/ajps.2014.521331
Abstract: Annual ryegrass (Lolium multiflourum) is the most important cool-season forage crop in Mississippi. It is seeded on more than 500,000 acres every year in the state and consequently seed companies intensely market the area with claims of superior genetic performance. Marketing literature observed in Mississippi focuses on the performance of tetraploid (4×) versus diploid (2×) with claims that 4× varieties provide better yield, disease resistance, and seedling vigor. These claims have rarely been substantiated on long-term performance variety trials. Archived Mississippi State forage variety test data from 1987 to 2012 were compiled for 10 diploid and tetraploid varieties grown at four physiographic locations (Starkville, Raymond, Newton, and Poplarville). Differences in the mean yields between 2× and 4× were only detected in Newton and Poplarville, where 2× varieties had a 4% yield advantage and 4× averaged 10% greater yields, respectively. Across the state, ryegrass yields for both ploidy levels increased over time (4×, R = 0.19931, P = 0.0105 & 2×, R = 0.18816, P = 0.0003), but correlations were variable by location. Biomass yields for both ploidy levels decreased over time in Starkville despite an increase in GDD (Growing Degree Days). With the exception of Raymond, year was the only factor influencing yield. The data suggest that ploidy level of ryegrass in Mississippi has minimal impact on seasonal yield production. However, genetic improvement other than polyploidy induction has increased yield over time.
Utilization of Annual Warm-Season Grasses as a Biofuel Source and Feedstock By-Product  [PDF]
Joshua A. White, Rocky Lemus
American Journal of Plant Sciences (AJPS) , 2014, DOI: 10.4236/ajps.2014.521342
Abstract: Annual warm-season grasses such as forage sorghum, sorghum × sudangrass hybrid and sundangrass are highly productive and valuable feed crops (rotational crop and silage). In addition, sugar in the stems of these warm-season grasses can be extracted and fermented, while the cellulose in the bagasse (pressed stalk) can be used for feedstock or cellulosic ethanol, making them versatile to both the forage and biofuel industry. Twelve annual warm-season grasses including forage sorghums, sudangrass, sorghum × sudangrass hybrid, and pearl millet were planted in 1.82 m × 3.35 m plots, harvested and treated as silage and hay before and after sap removal. Dry matter (DM) yield from a single harvest in 2011 and 2012 were collected and analyzed. Further analysis from the varieties includes evaluation for sap production, OBrix, crude protein (CP), Neutral Detergent Fiber (NDF), and Acid Detergent Fiber (ADF). Forage quality in silage was negatively affected by removing the sap before ensiling, producing quality similar to that of the hay samples. Sugar yields (SY) were not comparable to sweet sorghum yields reported in the literature, but when considering SY along with bagasse yield a few varieties may offer the potential as a dual purpose crop.
Alfalfa Establishment, Performance, and Persistence in Mississippi When Planted into a Bermudagrass Sward  [PDF]
Joshua A. White, Rocky Lemus
American Journal of Plant Sciences (AJPS) , 2015, DOI: 10.4236/ajps.2015.613224
Abstract: Alfalfa is a high quality forage that is not often utilized in the southeastern United States because of its perceived lack of adaptability to the area. However, the risk of growing alfalfa could be partially mitigated by its inclusion into an existing bermudagrass system that makes up a large portion of pastures and hay fields in Mississippi. Alfalfa was planted into an existing bermudagrass hay field at a rate of 17, 22, 28 and 39 kg·ha-1 in no-till and minimum till sod preparation and analyzed for three growing seasons. Tillage did not affect any of the variables observed but seeding rate and time affected DM (dry matter) yield, forage nutritive value and plot composition. The increasing alfalfa seeding rate increased alfalfa yield in the plot but this was isolated to only the first year. Dry matter yields decreased over the three years due to the decrease in alfalfa composition, but throughout the growing season DM yields increased after the first year suggesting bermudagrass recolonization within the plot. Forage nutritive value was positively affected with as little as 20% of the plot composed of alfalfa suggesting that even thinning stands by the third year might offer economic advantages.

Electronic Journal of Biotechnology , 2008,
Abstract: the genetic characterization of 117 peach and nectarine cultivars (prunus persica (l.) batsch) using microsatellite (ssr) markers is presented. analyzed genotypes include the complete list of cultivars under intellectual property (ip) protection in chile. one hundred and two out of the 117 cultivars under study could be identified using only 7 ssrs. other 5 cultivars were differentiated using 3 additional markers, but 5 pairs of genotypes were not differentiable. the average expected heterozygosity for the set of markers was 0.55, ranging from 0.28 in bppct-008 to 0.81 in cppct-022, with an f value of 0.37. a neighbor-joining dendrogram showed that, with few exceptions, peaches and nectarines clustered separately. these results are the basis for the development of a fingerprinting protocol for the unequivocal identification of most of the peach and nectarine cultivars officially registered in chile.

Abstract: tumor resistance to traditional cancer treatments poses an important challenge to modern science. thus, angiogenesis inhibition is an important emerging cancer treatment. many drugs are tested and corticosteroids have shown interesting results. herein we investigate the effect on microvessel density, survival time and tumoral volume of mice with ta3-mtx-r tumors. twenty six mice were inoculated with lxlo6 tumor cells, 4-5 days after injection, six mice were injected with pbs (group a) and twenty mice were treated with p-met (group b). all animals from group a died on day 22. group b was divided into bl (treated discontinued) and b2 (treated daily) and observed until day 88. all mice were processed for histo-immunohistochemical analysis and the blood vessels were counted. a decrease in microvessel density and tumoral volume and longer survival times were observed in the treated group. we propose that the antiangiogenic p-met effect explains, at least partially, its tumor inhibitory properties. as an important perspective, we will experimentally combine these strategies with those recently described by us with regard to the important antiangiogenic-antitumor effects of trypanosoma cruzi calreticulin. since the molecular targets of these strategies are most likely different, additive or synergic effects are envisaged.
