Association of Socioeconomic Factors to Domestic Violence and Murder of Women: The Case of Yucatán, México  [PDF]
Yolanda Oliva Pea
Psychology (PSYCH) , 2016, DOI: 10.4236/psych.2016.714175
Abstract: Registration of deaths classified as femicide, is an issue that occupies a breach of law, and that in this matter inconsistencies and absences in the information generated persist and persist in popular culture a strong stigma that various social groups and affected (victims) lead to underreporting of gender violence. Documentary research that conducted to determine the association of geographic areas and social factors related to violence to women occurred in the state of Yucatan during 2004 to 2014. Of the major findings of this study are: there are significant differences in the presence of domestic violence with the economic sector with a value of the test statistic of 13,500 with two degrees of freedom, a significant difference with a P-value of 0.001 (P-value < 0.05) was obtained, and P-value 0.000 (P-value < 0.05) for the murders of women. Geospatial distribution shows that the municipalities highest number of cases reported are found in large cities, and related to the three sectors of economic activity. Geographical distribution is North, South and East of the state. We conclude that it is required to have a surveillance system for the prevention of gender violence, also provide therapy to both men and women who have lived or have used violence systematically and taught by trained and sensitive to provide such care staff, and thus prevent deaths from gender violence.
Microbiota and Mycotoxins in Trilinear Hybrid Maize Produced in Natural Environments at Central Region in Mexico  [PDF]
Pea Betancourt, Silvia Denise
Advances in Microbiology (AiM) , 2016, DOI: 10.4236/aim.2016.69066
Abstract: Mycotoxigenic fungi and mycotoxins in 3 inbred lines (hybrids resistant to corn ear rot) were identified in twenty samples. The maize (Zea mays) accessions were collected in five plots of two municipalities in High Valley, state of Hidalgo. The fungal population was determined with a microbiological dilution method used two culture media (PDA and ELA), for the detection of mycotoxins with thin layer chromatography with visual inspection in UV light and a direct competitive enzyme-linked immunosorbent (ELISA). The results showed high moisture content in all hybrids evaluated on an average of 38.3% and a 1.8 × 103 UFC/g fungus, values within the permitted limits by the Mexican legislation; however the most prevalent fungi were Fusarium sp. (76%), Alternaria sp. (14%), Penicillium sp. (4%) and Aspergillus sp. (5%), and the species Aspergillus nidulas, Aspergillus flavus, Fusarium verticillioides, Fusarium poae, and Penicillium ochraceum. The aflatoxin concentration was observed in a range from 2 to 13 ng/g and 370 to 660 ng/g to fumonisins. It is concluded that trilinear corn hybrids have a variety of pathogenic potential fungi. The two genetic hybrids showed levels of aflatoxins and fumonisin safe for human consumption, contrary to one hybrid, with a content not suitable for human consumption. A better understanding of genetic hybrids corn will improve predictive mycotoxin contamination.

Abstract: This paper is a continuation of [D. Pe\~{n}a Pe\~{n}a, On a sequence of monogenic polynomials satisfying the Appell condition whose first term is a non-constant function, arXiv:1102.1833], in which we prove that for every monogenic polynomial $\mathbf{P}_k(x)$ of degree $k$ in $\mathbb R^{m+1}$ there exists a sequence of monogenic polynomials $\{M_n(x)\}_{n\ge0}$ satisfying the Appell condition such that $M_0(x)=\mathbf{P}_k(x)$.
On a sequence of monogenic polynomials satisfying the Appell condition whose first term is a non-constant function
Dixan Pea Pea
Mathematics , 2011,
Abstract: In this paper we aim at constructing a sequence $\{\mathsf{M}_n^k(x)\}_{n\ge0}$ of $\mathbb R_{0,m}$-valued polynomials which are monogenic in $\mathbb R^{m+1}$ satisfying the Appell condition (i.e. the hypercomplex derivative of each polynomial in the sequence equals, up to a multiplicative constant, its preceding term) but whose first term $\mathsf{M}_0^k(x)=\mathbf{P}_k(\underline x)$ is a $\mathbb R_{0,m}$-valued homogeneous monogenic polynomial in $\mathbb R^m$ of degree $k$ and not a constant like in the classical case. The connection of this sequence with the so-called Fueter's theorem will also be discussed.
Neurovascular Evaluation in Eugonadal Men with Type 2 Diabetes Mellitus and Erectile Disfunction: A Comparative Study between Responders and Not Responders to Phosphodiesterase 5 Inhibitors  [PDF]

Abstract: The aim of our study was to evaluate functional alterations of the corpus cavernusum and its correlation with the lack of response to treatment with PDE5i in eugonadal patients with Type 2 Diabetes Mellitus and Erectile Dysfunction. In this prospective randomized study we included 157 patients. All were treated with 5 mg tadalafil daily and 100 mg sildenafil on demand and the response to treatment was assessed in 6 month by dividing them into 2 groups: G1: Good response. Significative improvement of erectile function according to IIEF-5, and G2: There was not an improvement with the treatment. At the end of the treatment we performed neurological and vascular studies to both groups. Also we performed CC-EMG in order to evaluate penile autonomic neuropathy. 82 patients were included in G1 and 75 in G2. The time evolution of the ED was 1.5 years for G1 and 5 years for G2. Average fasting glucose and glycosilated hemoglobin values were significantly higher in G2 than in G1. Also we observed significant differences in penile vascular parameters between both groups. Peripheral neuropathy parameters did not show differences between both groups. Cavernous smooth muscle electromyography showed asynchronous and asymetric potentials in G1 (minimal autonomic neuropathy) and denervation potentials in G2 characteristic of severe CC damage. It is concluded that vascular and autonomic alterations are causes of severe CC damage and lack of response to treatment with PDE5i in this population. Peripheral neuropathy is not part of this process.
Influence of Water Quality on the Variation Patterns of the Communities of Benthic Macroinvertebrates in the Lakes of the Central Highlands of Peru  [PDF]
María Custodio, Richard Pe?aloza
Open Journal of Marine Science (OJMS) , 2019, DOI: 10.4236/ojms.2019.91001
Abstract:
The influence of water quality on the variation patters of benthic macroin-vertebrate communities in the lakes in the central highlands of Peru was eva-luated. Samples of water and sediments were collected in 23 different sam-pling sites last 2017. The physiochemical variables of water quality deter-mined on site were: DO, TDS, EC, temperature and pH. The results obtained revealed that the physiochemical indicators are within the environmental quality standards for water, except COD and BOD5. Regarding the benthic macroinvertebrates, four phyla were identified wherein the most common is the phylum Arthropoda having the abundance and richness of taxa. The PCA reduced the variables to a few significant components that caused variation in water quality between lakes. The cluster analysis in relation to the relative abundance of benthic macroinvertibrates grouped the 22 sampling sites into three groups with the similar characteristics. The PCoA analysis of the ben-thic macroinvertebrate communities showed a clear separation of sites. The SIMPER analysis at the family-level showed the distribution of the most common species. Therefore, at a significance level of 0.01 it demonstrates that there are significant differences between the number of species and abun-dance of the areas that were evaluated.

Abstract: Para estimar la evapotranspiración de referencia (ETo) en la zona norte de Las Tunas en Cuba, se realizó un estudio en el que se comparó su dinámica en la zona y se comparó con la evapotranspiración potencial (ETp) medida en lisímetro. Se emplearon los métodos de Penman Monteith (PM), Turc (T), Hargreaves Samani (HS), Thorntwaite (Th), Blaney Criddle (BC) y Blaney Morin (BM). Las fórmulas que mejor reflejaron el comportamiento real de la evapotranspiración de referencia en el norte de Las Tunas fueron la de Hargreaves Samani, Penman Monteith, Turc y Blaney Morin. Se obtuvo una alta correlación directa entre la evapotranspiración de referencia calculada y las variables del clima: temperatura media, insolación y evaporación. Se obtuvieron ocho ecuaciones de regresión para el cálculo de la evapotranspiración de referencia, factibles de poder utilizarse en el cálculo de las necesidades hídricas de los cultivos en las condiciones del norte de Las Tunas.
