Abstract: to evaluate the nutritive value of hydroponics forage corn (hfc) and the effects on bovine weight change, it was carried out an experiment in experimental farm located in maracay, aragua state, venezuela at 463 masl, 10o17?n and 67o37?w. the total annual rainfall was 1,013 mm with a mean temperature of 26oc. the soils were loam texture with 12 ppm of phosphorous and ph 8.5. ten growing bovines crossbreed 5/8 holstein x brahman were used, separated in different corrals (five animals/corral), under a stalled system. two treatments were evaluated: control, animals fed with grass only, and animals fed with 70% grass plus 30% of hydroponics forage corn. the animals were previously fed with the experimental diets for a period of 7 days and then for seven continuous weeks. the variables were: nutritive value of the grass and the hfc, nitrogen content in blood and semen, and weight change. the design was a complete randomize, where each animal was a repetition. the results showed that the nutritive value of the hfc was higher than the grass with a high protein content in the leaves and the whole plant (33.5 and 19.4%, respectively) (p<0.01). also, higher mineral content was observed in the hfc. significant differences were observed (p<0.05) between treatments for the consumption and use of the hfc. the nitrogen content in blood and semen of the animals showed no significant differences (1.3 and 0.7%, respectively) from the control. the weight gain was higher in the animals that consumed grass plus hfc (1.123 g/animal/d). it is concluded that the hfc could be a feeding alternative for the growing bovines in stalled conditions as a supplement in the base diet.

Abstract: Objetivo: Determinar la utilidad de la -hormona gonadotropina coriónica en fluidos vaginales para el diagnóstico de rotura prematura de membranas. Método: Estudio prospectivo y comparativo en 120 gestantes sanas divididas en 2 grupos, con rotura prematura de membranas y sin ella. Se determinaron las concentraciones de esta hormona en fluidos vaginales. Ambiente: Sala de Partos. Maternidad "Concepción Palacios", Caracas. Resultados: Las concentraciones de -hormona gonadotropina coriónica en fluidos vaginales superiores a 17,10 mUI/mL se relacionaron con rotura prematura de membranas, sensibilidad de 98,33 %, especificidad de 93,33 %, valor de predicción positivo 93,65 % y valor de predicción negativo 98,54 %. Conclusiones: Las concentraciones elevadas de hormona -hormona gonadotropina coriónica en fluidos vaginales constituyen un método confiable para el diagnóstico de rotura prematura de membranas. Objective: To determine the utility of the high concentrations of the -chorionic gonadotropin hormone in vaginal fluids in the diagnosis of premature rupture of membranes. Methods: Prospective and comparative study in 120 healthy pregnant women divided into 2 groups, with and without premature rupture of membranes. The concentrations of this hormone in vaginal fluids were determined. Setting: Delivery room. "Maternidad Concepcion Palacios", Caracas. Results: The concentrations of -chorionic gonadotropin hormone in vaginal fluids higher than 17.10 mUI/mL are related with premature rupture of membranes, with a sensibility of 98.33 %, specificity of 93.33 %, positive predictive value of 93.65 % and negative predictive value of 98.54 %. Conclusions: The high concentrations of -chorionic gonadotropin hormone in vaginal fluids constitute a reliable method for the diagnosis of premature rupture of membranes.

“Fear” Is a Book of Fiction Mixed with Real Events  [PDF]
Freddy A. Paniagua
Open Journal of Political Science (OJPS) , 2019, DOI: 10.4236/ojps.2019.91006
Abstract: Several book reviews were published prior to the publication of “Fear: Trump in the White House” on September 11, 2018, with emphasis on “terrifying scenes” (e.g., John F, Kelly reportedly said that Trump is an “idiot”). These reviews, however, did not discuss two major problems in “Fear,” namely, the contexts (i.e., environments, locations, settings, etc.) in which dialogues in “Fear” occurred and the probability that Woodward’s “sources” were present in such contexts, as well as the probability that such “sources” remembered and then reported verbatim extensive dialogues between two or more individuals in “Fear,” because of the limited capacity of the human short-term memory. This commentary suggests that Woodward did not “fabricate” the contents of “Fear,” as claimed by some in the White House, but argues that Woodward honestly believed what his “sources” reported to him without questioning such “sources” regarding the two major problems in “Fear.”

Abstract: Background: Patient satisfaction is related to the quality of services received and the extent to which specific needs are met. Satisfied patients are likely to come back for the health services and recommend it to others. Objective: To assess and compare patients’ satisfaction with the quality of prenatal/antenatal care (QPC) services received at a tertiary and secondary health facility in Ibadan, Nigeria. Methods: A comparative cross sectional study used an interviewer administered questionnaire to assess and compare the quality of antenatal care among women who had antenatal care and delivered live baby in two government health facilities—Adeoyo Maternity Hospital (secondary health facility) and University College Hospital (tertiary health facility). A total of 500 women were interviewed within 48 hours post delivery and data obtained was analyzed with SPSS version 20. Results: The mean age was 29.7 (SD = 4.95) years. About half of the respondents had more than four antenatal visits, almost two-thirds (61.4%) were primipara, and 55.6% delivered per vagina. Almost all (98.4%) the women were very satisfied with the QPC received while a little above half (54.0%) received high QPC. Health facility and mode of delivery were found to be significantly associated with the satisfaction of the QPC. Factors predicting high QPC comparing the tertiary and secondary health facility are “availability” (OR = 0.341, 95%CI = 0.173 - 0.672) and “support and respect” (OR = 5.599, 95%CI = 3.621 - 8.659) of health care
Fuzzy classification of phantom parent groups in an animal model

Genetics Selection Evolution , 2009, DOI: 10.1186/1297-9686-41-42
Abstract: To avoid the downside of such distinct classification, a fuzzy logic approach is suggested. A phantom parent can be assigned to several genetic groups, with proportions between zero and one that sum to one. Rules were presented for assigning coefficients to the inverse of the relationship matrix for fuzzy-classified genetic groups. This approach was illustrated with simulated data from ten generations of mass selection. Observations and pedigree records were randomly deleted. Phantom parent groups were defined on the basis of gender and generation number. In one scenario, uncertainty about generation of birth was simulated for some animals with unknown parents. In the distinct classification, one of the two possible generations of birth was randomly chosen to assign phantom parents to genetic groups for animals with simulated uncertainty, whereas the phantom parents were assigned to both possible genetic groups in the fuzzy classification.The empirical prediction error variance (PEV) was somewhat lower for fuzzy-classified genetic groups. The ranking of animals with unknown parents was more correct and less variable across replicates in comparison with distinct genetic groups. In another scenario, each phantom parent was assigned to three groups, one pertaining to its gender, and two pertaining to the first and last generation, with proportion depending on the (true) generation of birth. Due to the lower number of groups, the empirical PEV of breeding values was smaller when genetic groups were fuzzy-classified.Fuzzy-classification provides the potential to describe the genetic level of unknown parents in a more parsimonious and structured manner, and thereby increases the precision of predicted breeding values.Historically, genetic groups have been included in genetic evaluation models to account for selection not described by known genetic relationships. Introduction of animal models, which makes is possible to account for known relationships in the genetic evalua
