The efficacy of oxfendazole(OFZ) on Taenia hydatigena metacestodes, also called Cysticercus tenuicollis(C. tenuicollis), was studied in 648 raising pigs. This study was performed in Tumbes Department in Peru, an endemic area for cysticercosis. Pigs were randomized in two groups; untreated group(n = 142) did not receive any treatment and treated group(n = 506) received OFZ treatment at a single dose of 30 mg/kg body *** months after treatment, the pigs were necropsied. The prevalence of infection by C. tenuicollis among the pigs was 27.5%(39/142) and 2.0%(10/506) in untreated and treated groups, respectively. Untreated group was infested only with viable cysts, whereas treated group had no viable cysts. All the cysts found in treated group presented degeneration, with a thick membrane, and they contained milky fluid and fibrous tissue. A single dose of OFZ was effective against C. tenuicollis, thus providing an alternative drug for controlling this parasite in pigs.

Ammonia synthesis reactors operate in conditions of high pressure and high temperature. Consequently, the flow inside these reactors always presents interaction between components in the feed mixture. A modeling accounts these interactions with pressure, temperature and the molar fraction is essential to converter simulation more realistic. The compositional approach based on cubic equations of state provides the influences of the component of a gas mixture using mixing rules and binary interaction parameters. This multicomponent description makes the model more robust and reliable for properties mixture prediction. In this work, two models of ammonia synthesis reactors were simulated: adiabatic and autothermal. The fitted expression of Singh and Saraf was used. The adiabatic reactor model presented a maximum relative error of 1.6% in temperature and 11.4% in conversion while the autothermal reactor model presents a maximum error of 2.7% in temperature, when compared to plant data. Furthermore, a sensitivity analysis in input variables of both converter models was performed to predict operational limits and performance of the Models for Ammonia Reactor Simulation (MARS).

Links between institutional sectors and economic activities with National Accounting System of Mexico are studied used accounting multipliers. Key sectors had changed to strategic or leading as oil and gas extraction and dairy product manufacturing, i.e., Mexico went from a producer of goods to a service provider country, losing value added in their production chains. The mixed income is leading/independent economic activity for woman whose income is between 1 and 5 minimum wages. This is really important in the domestic economy through its impact on solidarity activities： providing care and support and providing food. Moreover, non-financial corporations and households of 10 or more minimum wages for income investing in strategic sectors such as retail trade and wholesale and manufacturing products derived from oil and coal. This is evidence of two Mexicos： the traditional and industrialized.

Today the most important challenge facing the pediatrician is the increasing prevalence of chronic diseases. With this regard, pediatricians play a key role in the management of these conditions. The closeness with the family, the knowledge of the clinical case and the care continuity allow the pediatrician to acquire a position of director of every case. When pathological events have a chronic feature, suddenly the quality of life of the whole family changes. For this reason the first communication of chronic disease is very important and the task of the pediatrician should be to provide a positive message to help the family in facing the difficulty of this new challenge. The bronchial asthma is the most common chronic disease worldwide. The incidence, the prevalence, and the mortality of the disease have increased in children over the past decades. These trends are particularly marked above all in preschool children. The success reached by Pediatricians is closely related to the compliance and the implementation of the therapy followed by the little patient and his family. With this regard authors, in this review, focus on the illustration of several strategies, based on the pediatrician’ skills and medicine documents, that can be used for the improvement of communication among pedia- trician-family and child, never forgetting the hu- man aspect of the same doctor, that should con- ciliate with the scientific knowledge in the taking care of a specific chronic disease.

Objectives: To project health outcomes for the period 2011-2031, in the Portuguese population aged 65 years and over, considering the expected changes in its demographic and educational structure. Methods: Demographic projections were produced using the multistate cohort component method. Logistic regression models were fitted to estimate current differences in health outcomes, using data from the Portuguese Health Survey. Such differences were applied to the projection results, in order to project the prevalence of “poor” self-reported health status, functional limitations and disability. Results: Our results point to a future improvement in the considered health outcomes. The prevalence of “poor” self-reported health status, functional limitations and disability will decrease in both genders, but will continue to be higher among women than men. Discussion: Beyond age and gender, other determinants of health, like education, should be considered when studying the possible evolution of health outcomes in an ageing population.

The electric power market is changing-it has passed from a regulated market, where the government of each country had the control of prices, to a deregulated market economy. Each company competes in order to get more *** and maximize its profits. This market is represented by a Stackelberg game with two firms, leader and follower, and the leader anticipates the reaction of the follower. The problem is formulated as a Mathematical Program with Complementarity Constraints (MPCC). It is shown that the constraint qualifications usually assumed to prove convergence of standard algorithms fail to hold for MPCC. To circumvent this, a reformulation for a nonlinear problem (NLP) is proposed. Numerical tests using the NEOS server platform are presented.

The present study reports effects of annealing treatment on the hardness of Ce75Al23Si2 rare earth-based metallic glasses (REMG). Then specimens were annealed at 100°C, 200°C, 250°C, 270°C, and 290°C five different temperatures for 30 minutes. After that, three different characteristic methods, including microindentation, X-ray Diffraction (XRD), and scanning electrical microscope (SEM) were conducted on the as received REMG sample and five annealed samples. XRD data demonstrate that the crystallization occurs in the sample at the annealing temperature as low as 200°C. The microindentation measurement shows that hardness of the REMG sample does not change at all before crystallization occurs in the sample and increases with the annealing temperature in the range of 200°C to 290°C. The average crystal size in the annealed samples was estimated using Debye-Scherrer equation to be 28-42 nm, in consistent with the SEM observation, indicating that nano-crystalline domains may give rise to the enhancement of hardness.
