Lived Experiences of Diversity Visa Lottery Immigrants in the United States

Every year approximately 50,000 people immigrate to the United States through the avenue referred to as the Diversity Visa (DV) Lottery. In this article, the authors present a literature review of immigration to the U.S. through the DV Lottery, reflect on their own immigration histories, and utilize phenomenology to investigate and describe participant feelings, expectations, and experiences as DV Lottery immigrants. Participants experienced mixed feelings, including high expectations prior to and difficulties after immigrating to the U.S. Findings presented include (a) life experienced in the U.S.; (b) access to learning and training opportunities; and (c) recommended support future DV Lottery immigrants

Contenido de lisina y triptofano en genotipos de maíz de alta calidad proteica y normal

El objetivo de esta investigación fue medir la humedad, grasa, proteína, ceniza y carbohidratos totales en la semilla completa, y cuantificar la lisina y triptófano en la semilla entera, el endospermo y el germen en cuatro genotipos de maíz QPM (CMSQ993027, CMSQ993037, CMSQ983051, CMSQ983015) y dos testigos (Variedad Roque I, maíz blanco y SBS400, amarillo), además de estimar la digestibilidad in vitro de la proteína en la masa. Este trabajo se desarrollo en Celaya, Guanajuato, México, en 2005. El diseño experimental fue completamente al azar con seis tratamientos y tres repeticiones. Para grasa, ceniza y carbohidratos no existió diferencia significativa. La media de proteína en los cultivares de maíz QPM fue de 10.38 y 10.31, y para los cultivares testigos blanco y amarillo fue de 10.93. El contenido de lisina y triptófano en el endospermo del QPM V6 duplicó el de los maíces testigo. El QPM V6 presentó el mayor contenido de triptófano. La digestibilidad in vitro de la proteína en la masa de maíz testigo y del maíz QPM V6 fue de 68 y 70%, respectivamente, y de 78% en harina de maíz QPM V6 para ¿atole¿

Effect of nitrogen and phosphorus fertilization on phytic acid concentration and vigor of oat seed (var. Saia) in Mexico [Efecto de la fertilización nitrogenada y fosforada en el contenido de ácido fítico y vigor de la semilla de avena de la variedad Saia en México]

Oats cereal is a worldwide significant crop. It is grown in restrictive climates and in rainy regions of temperate areas. Cultivation of oats produces high forage yields and grain quality, which gives it a wide variety of uses as animal feed and human food. However, the physiological quality of oat seeds in Mexico faces problems, which impact both their import and export. Phytic acid concentration in the oat seed plays a very important role since it affects seed viability, its germination capacity and potential seedling vigor. The objective of this study was to determine the effect of chemical fertilization on the phytic acid concentration and vigor of oat seeds. The study was conducted at the Technological Institute of Roque (ITR) and the National Research Institute for Forestry, Agricultural and Livestock in Celaya, Guanajuato in 2004 and 2005. Effects of two factors were evaluated at four levels each. Factor A was nitrogen fertilization (60, 100, 140, and 180 kg/ha). Factor B was phosphorus fertiliza ion (40, 80, 120 and 160 kg/ha). Variables measured were phytic acid, protein and amino acid concentrations, and vigor of oat seeds. Results indicated a cubic effect from nitrogen fertilization, and a quadratic effect from phosphorus fertilization, on the phytic acid concentration of oat seeds. The same trends were observed in seed vigor. However, there were no statistical differences in protein concentration for any of the study factors. Amino acid and phytic acid concentrations were not significantly related
