root rot and vine decline caused by monosporascus cannonballus is a major challenge for melon production world-wide. in recent years, a disease suggested to be related to this pathogen was observed 1-2 weeks prior to harvest in many melon production areas across iran. in this study, melon plants with symptoms of chlorosis, wilting, decline and/or sudden death were collected from melon growing a...

Ecologic studies of cancer screening examine cancer mortality rates in relation to use of population screening. These studies can be confounded by treatment patterns or influenced by choice of outcome and time horizon. Interpretation can be complicated by uncertainty about when mortality differences might be expected. The authors examined these issues in an ecologic analysis of prostate-specifi...

Between 1950 and 1980, China experienced the most rapid sustained increase in life expectancy of any population in documented global history. We know of no study that has quantitatively assessed the relative importance of the various explanations proposed for this gain in survival. We have created and analysed a new, province-level panel data set spanning the decades between 1950 and 1980 by co...

In this study, ochratoxin A (OTA) occurrence in Argentinean musts, wines and dried vine fruits was evaluated, alongside with the performance of OchraStar(TM) columns for OTA extraction. In all the three matrices analyzed, the OchraStar(TM) columns showed good performance. The analysis of natural occurrence of OTA in the red must and the red wine samples showed low incidence with low levels of m...

Ground-based proximal sensing of vineyard features is gaining interest due to its ability to serve in even quite small plots with the advantage of being conducted concurrently with normal vineyard practices (i.e., spraying, pruning or soil tilling) with no dependence upon weather conditions, external services or law-imposed limitations. The purpose of the present work was to test performance of...

Decisions made during the establishment and reworking of permanent cordon arms may have long-term consequences on vineyard health longevity. This review aims to summarise several important considerations that must be taken into account maintenance. Commonly practiced training techniques such as wrapping developing tightly around wire result in a constriction vascular system, becoming worse over...

in order to investigate the effect of application methods of znso4 on qualitative, quantitative and correction of zinc deficiency in grapevine, an experiment was conducted in completely randomized block design with 10 treatments and 4 replications. treatments included control, trunk injection three levels 1.5, 3 and 5 g/l, spray in three levels 1.5, 3 and 5 g/l and soil application (soil drench...

Recently, several copula-based approaches have been proposed for modeling stationary multivariate time series. All of them are based on vine copulas, and they differ in the choice of the regular vine structure. In this article, we consider a copula autoregressive (COPAR) approach to model the dependence of unobserved multivariate factors resulting from two dynamic factor models. However, the pr...

In the early years of the twentieth century, enormous concern was focused on the relationship between the health of the child and the welfare of the nation. In 1902, Leslie Mackenzie and Matthew Hay informed the Royal Commission on Physical Training (Scotland) that large numbers of children in Aberdeen and Edinburgh were suffering from serious medical conditions which could pose a threat to the...
