In recent years,there has been a growing need to understand how salinity affects microbial communities in agricultural *** and bacterial community diversities and structures were investigated by high-throughput sequencing analysis of their 16S rRNA in two arable soils with low electrical conductivity(EC)(2.3 and 2.6 dS m^(-1))and a saline soil(EC=17.6 dS m^(-1)).The dominant bacterial phyla in the soils were Proteobacteria(relative abundance(RA)=46.2%),followed by Acidobacteria(RA=13.1%)and Actinobacteria(RA=10.0%),whereas Serratia(RA=6.0%)and Bacillus(RA=4.0%)were the dominant bacterial *** Nitrososphaera(53.5%)was the dominant archaeal phylotype in the arable soils,whereas Nitrosopumilus(RA=0.4%)dominated in the saline *** archaeal and bacterial community structures were different between the soils and significantly correlated with soil sand,arsenic,barium,and antimony contents,but not with soil salinity.

Health 2018年第11期10卷 1554-1575页

作者： Giulia Savarese luna Carpinelli Pierpaolo Cavallo Maria Prosperina Vitale Department of Medicine and Surgery University of Salerno via Allende Baronissi (Sa) Italy Department of Phisic University of Salerno via Giovanni Paolo II n. 132 Fisciano (Sa) Italy Department of Economics and Statistics University of Salerno via Giovanni Paolo II n. 132 Fisciano (Sa) Italy

The present study examines the factorial structure and assesses the psychometric properties of the adapted multidimensional Health-Promoting Lifestyle Profile II Scale, considering a sample of Italian university students who participated to an online survey. The original 52-items Scale showed a high overall internal consistency. four of the six subscales were associated with good values of the Cronbach’s α coefficient, whereas two subscales had lower values. Hence corrected item-total correlation was calculated and 26 items that decreased the scale’s reliability were deleted. The remaining 26 items were first subjected to Principal Component Analysis that suggested a conceptually meaningful five-factor model. This result was further supported by the first-order confirmatory factor analysis, in which all the factor loadings were statistically significant. The internal consistency and the composite reliability for the reduced version of the Scale and its subscales have shown a good reliability for the measurement models. The multidimensionality of the scale was also confirmed by a second-order factor model.

The main objective of this study is to analyze through tripod strategy Peng, the basics of why the acquisition and sale of Grupo Modelo （which it is the largest brewer in Mexico with the highest market share） through analysis of the annual reports of the company. The analysis will be supported under three main theories： theory of industry, theory of resources and capabilities, and ultimately theory of institutions. The paper concludes with a compilation and analysis of information giving rise to answer the question why 6rupo Modelo sold？ And if have you had a positive result in the acquisition of Grupo Modelo by the company ABI？ The answer is yes. The sale price of the shares by Grupo Modelo was very high and it received an award of 30% over the closing price of the shares of the C series in 2012. So it was a good sale regarding previous observations.

fraser syndrome is a rare autosomal recessive multisystem disorder with a reported incidence of 0.043 per 10,000 live born infants and 1.1 in 10,000 stillbirths[1]. The condition is characterised by cryptophthalmos, cutaneous syndactyly, laryngeal and genitourinary malformations, craniofacial dysmorphism, orofacial clefting, musculoskeletal anomalies and mental retardation. The diagnosis can be made on prenatal scans, post natal clinical examination or on autopsy findings. We present a case of fraser syndrome and review of the ocular manifestations of this condition.
