Daily Fantasy sites engage in a legal war for survival
Over the past two years, the world has changed its perception of daily fantasy sports. FanDuel and DraftKings have taken the world by storm, making huge profits off even the casual fans desire to win money everyday, instead of just once at the end of a season. Lawmakers have noticed and are eager to regulate the business or ban it altogether, as seen in New York. What was once a weekend hobby is now a multi-billion dollar business. A business lawmakers say is just another form of gambling and doesn\u27t require skill
Evaluation of Precision Ingredient Inclusion on Production Efficiency Responses in Finishing Beef Cattle
Two randomized complete block design feedlot experiments were conducted over the course of two years. These experiments were conducted to investigate the effects of 1) evaluate the observed-to-expected ratio for ingredient inclusion using no commodity inclusion assistance technology or using commodity inclusion assistance technology; and 2) evaluate the influence that varying degrees (highly variable at random or 0.454 kg asfed tolerance for each ingredient) of accuracy on ingredient inclusion have on growth performance, carcass traits, efficiency of dietary NE utilization, and ingredient inventory management in finishing beef cattle. Experiment 1 used single source Black Angus heifers (n = 60; initial shrunk BW = 460 ± 26.2 kg). Experiment 2 used single source Charolais-Angus cross steers (n = 128; initial shrunk BW = 505 ± 32.1 kg). Heifers and steers were allotted to 1 of 2 dietary treatments: 1) 0.454 kg as-fed tolerance for each ingredient (CON), or 2) highly variable at random (VAR). In Exp. 1, applying a highly variable at random dietary inclusion did not affect ADG, dry matter intake (DMI), or feed conversion efficiency (P ≥ 0.15). There were no differences (P ³ 0.35) detected between treatments for HCW, dressing percentage, rib eye area, rib fat, USDA marbling score, KPH, yield grade, retail yield, empty body fat, or body weight at 28% estimated EBF. In Exp. 2, highly variable at random dietary inclusion showed an increase in (P £ 0.01) DMI and reduced (P £ 0.02) kg of gain to kg of feed (G:F) for VAR. However, no differences (P = 0.75) were detected between treatments for ADG. In addition, Net Energy for maintenance and gain was decreased (P £ 0.01) in VAR. Carcass characteristics for both treatments showed no treatment effect (P ³ 0.38) on HCW, dressing percentage, rib eye area, rib fat, KPH, Yield Grade, retail yield, empty body fat, or body weight at 28% estimated EBF. A tendency for increased USDA marbling score (P \u3e 0.08) was noted in VAR. Under the conditions of this experiment, randomly altering ingredient proportions negatively affected feed efficiency with no change in carcass characteristics
Avaliação da freqüência de Lasiodiplodia theobromae em plantas cítricas com sintomas típicos de descamamento eruptivo.
O fungo Lasiodiplodia theobromae (Pat.) Griffon & Maubl., é um patógeno comumente encontrado nas regiões tropicais e subtropicais. Capaz de infectar tecidos vegetais, isoladamente ou em associação com outros patógenos, pode causar sérios prejuízos a numerosas espécies cultivadas.Em paralelo aconteceram também os seguintes eventos: V Seminário de Pesquisa do Recôncavo da Bahia; V Seminário Estudantil de Pesquisa da UFRB; V Seminário da Pós-Graduação da UFRB; II Seminário Regional de Pesquisa da EBDA; 5ª Jornada Científica da Embrapa Mandioca e Fruticultura; VIII Seminário Estudantil de Pesquisa e Extensão da FAMAM; Semana de Ciência, Tecnologia e Inovação no Agronegócio; Fórum de Gestores de Iniciação Científica e Tecnológica da Bahia; II Simpósio Baiano de Defesa Agropecuária; I Semana de Educação Tutorial da UFRB
The derivations of some evolution algebras
In this work we investigate the derivations of n−dimensional complex
evolution algebras, depending on the rank of the appropriate matrices. For evolution
algebra with non-singular matrices we prove that the space of derivations is zero. The
spaces of derivations for evolution algebras with matrices of rank n−1 are described.Junta de Andalucía FQM-14

Electronic properties of SnO2-based ceramics with double function of varistor and humidity sensor
This is the post-print version of the article. The official published version can be obtained from the link below - Copyright @ 2010 AD-Tech.Tin dioxide based varistor ceramics SnO2-Co3O4-Nb2O5-Cr2O3-xCuO (x=0; 0.05; 0.1 and 0.5) were made and their electrical properties were studied. The highest nonlinearity coefficient and electric field (at current density 10-3 A cm-2) were obtained for 0.1 mol.% CuO addition. It was observed that low-field electrical conductivity is increased with relative humidity, therefore, materials obtained exhibit double function of varistor and humidity sensor. The highest humidity sensitivity coefficient is found for SnO2-Co3O4-Nb2O5-Cr2O3 ceramics (without CuO). Observed varistor and humidity-sensitive properties are explained in the frames of grain-boundary double Schottky barrier concept as a decrease of the barrier height with electric field or relative humidity. Using suggested simple theory and data obtained on isothermal capacitance relaxation, the energy of the grain-boundary monoenergetic trapping states were estimated. These values are less than found for activation energy of electrical conduction (as a measure of the barrier height). These observations confirm the barrier concept.This work is funded by the Royal Society, United Kingdom (2007R1/R26999)
