The purpose of this study was to develop an analytical model to predict the time required for cracking of concrete due to corrosion of the iron reinforcement. The concrete and cement specimens used for this study were batched with cover material ranging from 0.75 to 1.3 in (1.91 to 3.30 cm). The extent of cover material was not formulated into the model under the assumption that crack initiation would tend to produce visible cracking within a relatively short time period. The model was derived using both Hooke’s Law and the volume expansion induced by the corrosion oxides. Correlation achieved with specimen cracking data from the literature was relatively good with a 95% level of confidence. This model presents a key benefit to facility and infrastructure managers by enabling them to plan the time when corrosion mitigating actions are required. It also provides a significant convenience as the condition of the concrete structure or its environment changes over time. The only parameter that needs to be updated over time is the corrosion rate measurement. This single parameter captures the most influential impact that stems from several other parameters which tend to be required in models that are more mechanistically definitive.

综合业务公司在追求增长时总是利用两个传统战略：通过兼并和收购来扩张他们的业务组合，或通过有机增长来扩展各项业务。这两个战略现在看起来都颇具挑战性。首先是并购战略在大多数情况下注定充满风险和艰辛：BCG的研究显示，近三分之二的并购案对公司价值造成重创。另一方面，促进各个业务的有机增长虽然看起来非常重要，却不能产生足够的增长来满足公司（和股东）的总体目标。

Hepatitis E virus （HEV） infection is a common causeof acute clinical hepatitis worldwide. HEV is an RNAcontainingvirus and the only member of the genusHepevirus in the family Hepeviridae . Human HEV isclassified into four genotypes widely distributed acrossthe world. The virus is mainly transmitted via the fecaloralroute, and water-borne epidemics have becomecharacteristic of hepatitis E in developing countries,including those in Latin America. The zoonoticpotential of HEV is broadly recognized. Thus, thereis an urgent need to re-evaluate virus transmissionscenarios and to enforce epidemiological surveillancesystems. Additionally, it is known that HEV infections,initially defined as self-limiting, can also take chroniccourses in immunocompromised patients. Moreover,we recently reported a high seroprevalence of HEV insamples from cirrhotic patients with no other etiologicalagents present, suggesting the potential role of HEVin the development of chronic liver illness. In thisreview, HEV genomic variability, transmission, chronicinfectious course, zoonotic potential and treatmentare discussed. Focus is placed on the impact of HEVinfection in Latin America, to support the developmentof specific control strategies and the handling of thisimportant and typically imperceptible viral infection.

AIM: To investigate whether regional geography influences ethnic and gender trends for the development of gastric cancer(GC).METHODS: This retrospective analysis of the INVISION patient database at Louisiana State University Health Sciences Center-Shreveport(LSUHSC-S), a southern United States regional hospital, was performed from 2005-2011. Using the international statistical classification of diseases 9(ICD-9), inpatient, day surgery outpatient, and emergency outpatient diagnosis codes entered into medical records were used to identify GC patients. For each study year, the patients were evaluated for age, ethnicity, and gender, and each patient was counted only once throughout the study. Subsequent patient encounters were counted as visits and separated by inpatient and clinic visits. Complex or severe disease may require more frequent and intensive clinical management; therefore, we evaluated annual clinic visits as "surrogate markers" of disease severity. Finally, we studied the primary diagnosis for Helicobacter pylori(H. pylori) infection(ICD-9 code 41.86) as an additional factor that might increase the risk of ***: A total of 285 patients were diagnosed with GC at LSUHSC-S between 2005 and 2011. African Americans(181 patients, 89 males and 92 females, 63.5% of total patients) had significantly higher frequencies of GC diagnosis compared with non-Hispanic whites(104 patients, 54 males and 50 females, 36.5% of total patients), at a ratio of 1.74(P = 0.002). Within each ethnic group, men and women were diagnosed at approximately equal annual rates. Our findings differed significantly from United States national trends, which found that African American females and white females had lower risks for GC than their corresponding male counterparts. The United States national trend between 2005 and 2011 showed that African Americans males had a higher incidence of GC, with an annual mean(per 100000) of 16.31 ± 0.76 compared with white males(9 ± 0.1, P < 0.001),
