Neutral Higgs bosons in the SU(3)(L)circle times U(1)(N) model

The SU(3)(L)circle times U(1)(N) electroweak model predicts new Higgs bosons beyond the one of the standard model. In this work we investigate the signature and production of neutral SU(3)(L)circle times U(1)(N) Higgs bosons in the e(-)e(+) Next Linear Collider and in the CERN Linear Collider . We compute the branching ratios of two of the SU(3)(L)circle times U(1)(N) neutral Higgs bosons and study the possibility to detect them and the Z' extra neutral boson of the model.

The connection between the university and the productive sector: technological transference

This paper analyzes the process of technological transfer from the university to the industry, firstly through a brief overview of the innovation role, and particularly of universities, according to various economic theories (Neoclassical Theory, Schumpeter and his followers, and Marxism) -- Next, the Bologna Process, a specific European case of technology transfer, is considered from empirical sources, official speeches, regulations and official documents -- Finally, the general trend of explicit relation in Argentina between the university and the productive sector is briefly analyzed from certain empirical evidence, official speeches and policies, in order to guide the understanding of this process in Latin America -- The main conclusion of the study aims to consider technological transfer as intrinsic and necessary for the contemporary capitalism

Local productive arrangements for biodiesel production in Brazil: Environmental assessment of small-holders integrated oleaginous crops management.

Sustainability assessments were carried out in small-holders? farms in four territories where productive arrangements have been organized for production of minor oleagi- nous crops under the Brazilian biodiesel program. The study aimed at checking local impacts of the biodiesel productive chains at the rural establishment scale, and pro- moting the environmental performance of the selected farms, henceforth proposed as sustainable management demonstration units. Assessments were carried out with the APOIA-NovoRural system, which integrates 62 objective and quantitative indicators re- lated to five sustainability dimensions: i) Landscape Ecology, ii) Environmental Quality (Atmosphere, Water and Soil), iii) Socio-cultural Values, iv) Economic Values and v) Management and Administration. The main results point out that, in general, the eco- logical dimensions of sustainability, that is, the Landscape Ecology and Atmosphere, Water, and Soil quality indicators, show adequate field conditions, seemingly not yet negatively affected by increases in chemical inputs and natural resources use predicted as important potential impacts of the agro-energy sector. The Economic Values indica- tors have been favorably influenced in the studied farms, due to a steadier demand and improved prices for the oleaginous crops. On the other hand, valuable positive conse- quences expected for favoring farmers? market insertion, such as improved Socio-cultural Values and Management & Administration indicators, are still opportunities to be ma-terialized. The Environmental Management Reports issued to the farmers, based on the presented sustainability assessment procedures, offer valuable documentation and com-munication means for consolidating the organizational influence of the local productive arrangements studied. These productive arrangements were shown to be determinant for the selection of crop associations and diversification, as well as for the provision of technical assistance and the stabilization of demand - conditions that promote value aggregation and income improvements, favoring small-holders? insertion in the market. More importantly, these locally organized productive arrangements have been shown to strongly influence the valorization of natural resources and environmental assets, which are fundamental if sustainable rural development is to take place under the emerging agro-energy scenario.

Hematology and productive performance of nile tilapia (Oreochromis niloticus) naturally infected with Flavobacterium columnare

Columnaris disease is one of the main causes of mortality in tilapia rearing and is responsible for large economic losses worldwide. Hematology is a tool that makes it possible to study organisms' physiological responses to pathogens. It may assist in making diagnoses and prognoses on diseases in fish populations. The hematological variables of nile tilapia were studied in specimens with a clinical diagnosis of columnaris disease and in specimens that were disease-free. The total erythrocyte count, hemoglobin rate, hematocrit percentage, mean corpuscular hemoglobin (MCH), mean corpuscular hemoglobin concentration (MCHC), mean corpuscular volume (MCV), organic defense blood cell percentages (leukocytes and thrombocytes) and hepatosomatic and splenosomatic index were determined. The results showed that there were changes in the erythrocytic series and in organic defense blood cells, in the fish infected with the bacterium, with reductions in erythrocytic variables and significant increases in the numbers of circulating lymphocytes and neutrophils.

Circle squared: an interactive environment

Circle Squared by David Lyons and Raz Ullah, brings together large-scale projected motion graphics and a dynamic soundscape to create a playful, digitally interactive artwork. The sounds are drawn from heightened and abstracted recordings of the printmaking process, and these – along with the changing CMYK colour palette – are triggered by audience interactions with sensors and projectors within the installation.

Equilibrium existence in the circle model with linear quadratic transport cost

We treat the problem of existence of a location-then-price equilibrium in the circle model with a linear quadratic type of transportation cost function which can be either convex or concave. We show the existence of a unique perfect equilibrium for the concave case when the linear and quadratic terms are equal and of a unique perfect equilibrium for the convex case when the linear term is equal to zero. Aside from these two cases, there are feasible locations by the firms for which no equilibrium in the price subgame exists. Finally, we provide a full taxonomy of the price equilibrium regions in terms of weights of the linear and quadratic terms in the cost function.

Healing wounds institutional strength, peacebuilding, and productive entrepreneurship – exploratory analysis on 23 departments of Colombia

Este estudio presenta un análisis exploratorio sobre la correlación entre la fortaleza institucional, las condiciones de paz, y el emprendimiento en una muestra de 23 departamentos en Colombia usando datos de 2014. Para llevar a cabo este objetivo se propusieron y construyeron tres índices siguiendo definiciones conceptuales seminales o estándares de evaluación internacional, a saber: 1) El Índice de Fortaleza Institucional, 2) El Índice de Construcción de Paz (construido a partir del índice de paz negativa y el índice de paz positiva) y 3) El Índice de Emprendimiento Productivo. Los resultados no muestran una correlación significativa entre todos los tres índices. Por un lado, existe una correlación significativa (p<0.05) entre los índices de fortaleza institucional y emprendimiento productivo. Por otro lado, existen correlaciones negativas no significativas entre los índices de paz positiva y fortaleza institucional, emprendimiento productivo y paz positiva y emprendimiento productivo y construcción de paz. En un segundo acercamiento, la población de los departamentos fue la variable con mayor número de correlaciones significativas (p<0.01) entre variables relacionadas con emprendimiento productivo, empleo, producto interno bruto, sofisticación industrial, innovación (patentes) y crimen. Finalmente, se discuten las conclusiones y las futuras investigaciones.

First reproductive and productive results on “Ribatejano pig”

The present trail aimed to study the effect of crossbreeding between Alentejano (AL) and Bísaro (BI) swine breeds (“Ribatejano pig”) on some reproductive and productive traits. Nine AL gilts and sows and six BI gilts were crossed with BI and AL boars, respectively. Mating and farrowing dates, prolificacy and litter size at 28d were registered for all sows. The pregnancy length of AL sows was shorter (111±0.4d vs 113.7±0.5d; p=0.002) than the observed on BI females. The BI gilts presented higher prolificacy rate than AL on both total born (11.0±1.0 vs 6.7±0.8; P=0.004) and born alive piglets (10.0±1.0 vs 6.7±0.8; p=0.026). The mortality rate was similar in both genotypes (p=0.255) being on average 12%, therefore at 28d after farrowing the litter size remained higher in BI sows (8.5±0.8 vs 6.1±0.6; p= 0.032). A subset of each genotype (4 gilts) was supervised during farrowing and lactation (until 28d) and piglets were weighed at birth, 24h and 28d of live. Farrowing length was not significantly different (p=0.253) between genotypes, averaging 97±22 min. When compared to ALBI (AL x BI) piglets, the BIAL (BI x AL) piglets were heavier at birth (1402±46g vs 1209±36g; p=0.002). Colostrum intake of piglets per kg of birth weight on the first 24h of life was similar between genotypes (p=0.735) being 289±15g for ALBI and 281±19g for BIAL piglets. The growth rate of piglets from birth to 28d and piglet weight at 28d was not different between genotypes (p=0.161 and p=0.091) averaging 195±6g and 6761±181g, respectively. Litter weight at 28d tended (P=0.06) to be higher on ALBI litters (56.6±4.0kg) than BIAL litters (43.2±4.0kg). This results obtained within the frame of Treasure project* are, at our knowledge, the first data of these crossbred piglets and could be used in future as reference for further studies and also for farmers that may try these cross on a commercial basis.

Productive performance and parasitological control of kids supplemented with umbu fruits (Spondias tuberosa Arruda).

Native fruits from Caatinga vegetation can be an important alternative to improve the productive performance of kids in the semi-arid region of Brazil. This work aimed to evaluate the effect of supplementation with Umbuzeiro fruits in natura over the weight gain and anthelmintic control of kids kept in Buffel grass pasture in the semi-arid zone of Pernambuco, Brazil. Twenty-four castrated, crossbreed kids were allocated into three treatments: 1) Control (n = 8) fed exclusively with Buffel grass; 2) Umbu 1x (n = 8) fed with fruits once a week and 3) Umbu 3x (n = 8) fed with fruits for three times a week. The following parameters were evaluated: variation of body weight, faecal egg counts (FEC) and coproculture. Overall, the average consumption of Umbu fruits in natura was 1.48 kg/animal/day, which corresponded to 133.5 g daily dry matter intake (DMI/animal/day). There were no significant difference (P>0.05) for any parameters evaluated. During the experimental period, the overall daily weight gain was variable between 108.75 to 116.70 g/animal/day and the average FEC was 436 eggs. In the present study, the goat kids supplemented with fresh umbu fruits showed a good productive performance, however the supplementation with umbu did not control the infestation of gastrointestinal nematodes in kids.
