This present study was elucidated the cytological effects of maize due to ageing (storage) in different packaging material. This study revealed that the cytological anomalies in somatic cells of maize inbreds (CM-138 and CM-142) due to storage in jute and plastic bags. For the cytological impact of storage, inbreds were stored in jute and plastic bags for different periods i.e. 4, 8 and 12 mont...

BACKGROUND Although self-inflating bags are widely used for manual hyperinflation, they do not allow ventilation parameters, such as pressure or volume, to be set. We studied the ventilation performance of neonatal and pediatric self-inflating bags. METHODS We asked 22 physiotherapists to manually hyperinflate 2 lung models (neonatal and pediatric), using self-inflating bags from 3 manufactur...

Radon detectors are widely used for research and for monitoring indoor and outdoorradon. During some applications, detectors need to be enclosed in barrier bags which arecompletely transparent to radon. In other applications, radon detectors need to beenclosed in barrier bags that are opaque to radon. In certain applications, barrier bagsmay provide resistance to human manipulat...

In this paper, we formulate a new multi-graph learning task with only positive and unlabeled bags, where labels are only available for bags but not for individual graphs inside the bag. This problem setting raises significant challenges because bag-of-graph setting does not have features to directly represent graph data, and no negative bags exits for deriving discriminative classification mode...
