Abstract

In this work we present an analysis of production and signature of charged Higgs bosons $H_2^{\pm}$ in the version of the 3-3-1 model containing heavy leptons at the CLIC (Cern Linear Collider). The production rate is found to be significant for the direct production of $e^{-} e^{+} \rightarrow H_{2}^{+} H_{2}^{-}$. We also studied the possibility to identify it using their respective branching ratios., Comment: 16 pages, 9 Figures. arXiv admin note: substantial text overlap with arXiv:1408.5944; text overlap with arXiv:1311.0845, arXiv:1205.4042

Abstract

We present an analysis of production and signature of neutral Higgs bosons on the version of the 3-3-1 model containing heavy leptons at the Large Hadron Collider (LHC). The production rate is found to be significant with a clear signature ($\sqrt{s}=14$) TeV, showing that these scalars can be detected in this accelerator. We also studied the possibility to identify them using their respective branching ratios. Cross section are given for two collider energies, $\sqrt{s} =$ 8 TeV and 14 TeV. Event rates and significances are discussed for two possible values of integrated luminosity, 10 fb$^{-1}$ and 300 fb$^{-1}$., Comment: 27 pages 10 figures

Abstract

We studied the production and signatures of doubly charged Higgs bosons in the process $\gamma e^- \rightarrow H^{--}E^+$, where $E^+$ is a heavy lepton, at the $e^-e^+$ International Linear Collider (ILC) and CERN Linear Collider (CLIC). The intermediate photons are given by the Weizs$\ddot{a}$cker-Williams and laser backscattering distributions. We found that significant signatures are obtained by bremsstrahlung and backward Comptom scattering of laser. A clear signal can be obtained for doubly charged Higgs bosons, doubly charged gauge bosons and heavy leptons.

Abstract

En los últimos 30 años, la Zona Metropolitana de Guadalajara (ZMG) ha experimentado un acelerado crecimiento urbano-industrial, realidad traducida en contaminantes nocivos para la salud de la población. El objetivo de este trabajo fue analizar la concentración de dióxido de azufre (SO 2) y de nitrógeno (NO2) en el aire, así como, los iones hidrógeno (H+), sulfatos (SO 4-2) y nitratos (NO3-) durante la temporada de lluvias del año 2005. Mediante una red de estaciones de monitoreo, se obtuvieron resultados que revelaron acidez significativa al norte-noroeste y sureste. Las concentraciones máximas de SO4-2 ocurrieron al sureste y sur, mientras que, las de NO3- se localizaron al sur. Los niveles máximos de SO2 y NO2 sucedieron en el período seco, disminuyendo en el húmedo. Se observó mayor frecuencia de acidez por NO2 siendo el indicador principal las fuentes móviles.

Abstract

La hipoplasia del esmalte es un desarrono defectuoso o incompleto del tejido y se produce como una perturbación temporal en la formación de la matriz del esmalte; interesa tanto a la dentición primaria como a la permanente, y presenta una amplia variación en su aspecto clínico. Cuando se produce una perturbación en la etapa de calcificación del diente, se habla, no de hipoplasia, sino de hipocalcificación (6).

In the last 30 years, the Metropolitan Zone of Guadalajara (ZMG) has experienced a quick urban and industrial growth, situation which results in high rates of pollution and poor air quality harmful to the health of the population. The main purpose of this work was to analyze the SO2 and NO2 in the air, as well as ions H+, SO 4-2 and NO3- during the wet season of 2005. Results of the network of monitoring stations showed significant acidity in north-northwest and southeast of the study area. The maximum concentrations of SO 4-2 occurred in southeast and south, while the maximum NO3- was found in the south. Maximum levels of SO2 and NO2 occurred in the dry season, but it decreased in wet season. The higher frequency about acidity produced by NO2 is caused by mobile sources as the primary indicator.

Abstract

Mitotic and meiotic studies were performed on Allium fistulosum, A. cepa, their F1 hybrid, and ten selected backcross (BC)1 plants [(A. fistulosum x A. cepa) x (A. cepa)]. Each BC1 plant had at least one A. cepa isozyme allele (Pgi, Idh, or Adh). Chromosome morphology and behavior differed among plants. Meiocytes were observed with one, two, or three bridges and/ or fragments, indicating at least three paracentric inversions between A. fistulosum and A. cepa. Unusual crossing over and multivalent associations suggest that the 5F subtelocentric chromosome of A. fistulosum is involved in at least one translocation. The number of bridges and fragments and multivalent associations varied between the F1 hybrid and BC1 progenies. The F1 hybrid and all BC1 progenies were either sterile or had very little seed set. Fertility was not restored in any of the selected BC1 plants.

Abstract

An F2 population (Allium fistulosum x A. cepa) of 20plants, 10 BC1,[(A. fistulosum x A. cepa) x A. cepa], and 50 BC2 plants, [(A. fistulosum x A. cepa) x A. cepa] x A. cepa were studied cytogenetically and characterized for four isozyme alleles plus various morphological characteristics. All of the progenies were in A. fistulosum (the bunching onion) cytoplasm. In the F2 population we observed non-random chromosomal and allelic segregation, suppression of bulb onion allelic expression, and abnormalities in mitosis and meiosis. Most BC2 plants resembled A. cepa (the bulbing onion) morphologically, but anthers, filaments, pistils, and petals were abnormal. Only 3 plants, and these were most nearly like the F1 hybrid morphologically, produced any seeds.The data and observations support the hypothesis of nuclear-cytoplasmic incompatibility interactions between the bunching and bulb onion species.

Abstract

Previous studies demonstrated that it is possible to optimize Oreochromis mossambicus fry production in a recirculating system by means of supplemented diets with Artemia's cysts. In the present work, productive yields of Oreochromis niloticus, species kind highly cultured in México and worldwide, and O. mossambicus fry are reported in order to know the possible differences on growth and survival. Tilapia fry with a mean wet weight of 0.011 ± 0.002 and 0.017 ± 0.005 g(O. niloticus and O. mossambicus, respectively), were fed with a dietary inclusion of 10% of decapsulated Artemia cysts (QDS) in a starter commercial diet, during the first month of exogenous feeding after yolk absorption. Fry were reared in a recirculating system at a stocking density of 5 org/l (5000 org/m3). Diet was given at a daily feeding rate of 25% of body biomass, four times a day. Final mean weight and survival for O. niloticus and O. mossambicus were 1.31 ± 0.15 and 1.60 ± 0.22 g, and 90 % y 97.5 %, respectively. There were no significant differences (p > 0.05) in final yields (mean weight, length, biomass/l, daily weight gain, specific growth, feed conversion and survival) between species. The results suggests that an inclusion of 10% of QDS in the hatchery diet may improve growth performance of both Oreochomis species under similar management conditions. Technical and economic considerations should be carefully reviewed before using QDS at commercial level. [ABSTRACT FROM AUTHOR]

50. A Survey of Hepatitis B Virus and Hepatitis E Virus at the Human-Wildlife Interface in the Peruvian Amazon.

Author

Abstract

Hepatitis B virus (HBV) and Hepatitis E virus (HEV) are zoonotic pathogens posing significant health concerns in rural Amazonia, a region marked by high endemicity, poverty, and limited healthcare access. However, the epidemiology of HBV and HEV in this ecosystem remains underexplored. This study examines the circulation of HBV and HEV at the human-wildlife interface and identifies risk factors within an isolated Amazonian indigenous community reliant on hunting for subsistence. Antibodies against HBV core antigens (HBcAbs) were found in three wildlife species: Cuniculus paca (0.8%), Tayassu pecari (1.6%), and Mazama americana (4.1%), marking the first record of HBV antibodies in free-ranging wildlife in the Amazon. However, further research is necessary to identify circulating strains and their relation to human HBV. HBcAbs were also detected in 9.1% of human samples, confirming exposure to HBV in the region. HEV IgG antibodies were present in 17.1% of humans and were associated with higher age. All wildlife and domestic animal samples tested negative for HEV, but transmission through consumption of wild animals and contaminated water needs further investigation. The identified risk factors highlight the urgent need for measures to promote safer food handling, improved sanitation, hygiene, and practices related to contact with wild animals.
