This paper uses Granger causality test techniques to investigate the causal order of the air-sea interactions between the anomalous NAO index and the NCAR/NCEP SST anomalies over the northern hemisphere. Compared to the simple lead/lagged correlation, the Granger causality analysis is generally more reliable since it ensures that any apparent oceanic influence upon the atmosphere is uniquely pr...

[1] We have analyzed the mean climate response pattern following large tropical volcanic eruptions back to the beginning of the 17th century using a combination of proxybased reconstructions and modern instrumental records of cold-season surface air temperature. Warm anomalies occur throughout northern Eurasia, while cool anomalies cover northern Africa and the Middle East, extending all the wa...

theories and the existing studies predict different the relationship between external financing and investing activities and the stock returns. but almost of them predict that there is negative relationship separately between financing and investing activities with stock returns. this study examined the assumption that there is a significantly negative relationship between external financing ac...

From October 1977 to December 1988, 108 neonates born with esophageal atresia (EA) and/or a tracheoesophageal fistula (TEF) were treated at the Bristol Royal Hospital for Sick Children. An incidence of I :4000-4500 live births was noted. 1I2.4% had the common- type anomaly, 5.5% had pure esophageal atresia, and 6.5% had an H-type anomaly. 2.8% had upper and lower fistulae and 2.8% had uppe...

Introduction: Infants born with congenital anomalies demand individualized nutritional evaluations and recommendations. The anatomical changes of neonatal surgical diseases create specific physiological constraints.Patients with different congenital anomalies have different nutritional support needs. It is essential to know the exact physiology of these anomalies in order to be able to manage a...

background: tobacco use has toxic effects on different organs. this study was carried out to assess the effect of indigenous tobacco both in smoking (bidi) and smokeless (gutkha, zarda and khaini) forms on buccal cells at chromosomal level, through assessment of different nuclear anomalies as biomarker. methods:this study was done on people living in durgapur and its adjacent areas, west bengal...

introduction: orofacial clefts are among the most common congenital anomalies. patients presenting with orofacial clefts often require surgery or other complex procedures. a cleft lip or palate can be a single anomaly or a part of multiple congenital anomalies. the reported prevalence of cleft disease and associated anomalies varies widely across the literature, and is dependent on the diagnost...

1. introduction the position of iran in the subtropical region that has made its arid and semiarid climate and the topographic diversity changes this trend of climate. therefore, climate hazards such as frost, flood, dust storm, drought, temperature anomalies, heavy rainfall, avalanches, snow, sleet, etc occur in iran. the northwest of iran experiences the above conditions following the arrival...
