BACKGROUND A high twinning rate and an increased risk of mortality among twins contribute to the high burden of infant mortality in Africa. This study examined the contribution of twins to neonatal and post-neonatal mortality in The Gambia, and evaluated factors that contribute to the excess mortality among twins. METHODS We analysed data from the Basse Health and Demographic Surveillance Sys...

Humulus lupulus is a dioecious twining herb, with an outstanding vertical development capacity. Hop plants are usually grown on trellises up to 4.5 6.0 m high, whose management requires intense use of water, fertilizers, pesticides, and labor. In semiarid Mediterranean areas, where native resources often scarce, the adoption low-trellis farming systems could be sustainable option for hop cultiv...

Arabidopsis spiral1 (spr1) mutants show a right-handed helical growth phenotype in roots and etiolated hypocotyls due to impaired directional growth of rapidly expanding cells. SPR1 encodes a small protein with as yet unknown biochemical functions, though its localization to cortical microtubules (MTs) suggests that SPR1 maintains directional cell expansion by regulating cortical MT functions. ...

neck and face, of a sort of papula), rather resembling urticaria, and about the size of an 8 anna piece, red apparently from scratching them : they are very itchy ; headache relieved. 5th.?One or two additional wheals have broke out, but most of the others are now disappearing; complains of a bitter taste in the mouth. 6th.?The eruption going off; much distresssd with cough in the night. 7th.?N...

Studies on twin pregnancy are uniquely important to Africa and particularly Nigeria where the highest incidence in the world exists. This study was designed to determine the trend, rate, and obstetric outcomes of twin deliveries in the University of Abuja Teaching Hospital, Gwagwalada. This was a retrospective study of twin deliveries in the hospital over a period of 10 years. During the study ...

The perennial and evergreen twining vine, Lonicera japonica is an important herbal medicine with great economic value. However, gene expression information for flowers and leaves of L. japonica remains elusive, which greatly impedes functional genomics research on this species. In this study, transcriptome profiles from leaves and flowers of L. japonica were examined using next-generation seque...

The authors research and develop a flapping wing type robotic fish (shark ray robot) with flexible tail fin as an advanced underwater vehicle. The flapping wing consists of multijoints mechanism to get lift force and rotation moment for high maneuvering characteristics of motion. The tail fin is designed by elastic oscillating system and developed to produce strong propulsion force for higher s...

Spiral phyllotactic patterning is the result of intricate auxin transport relationships in the shoot apical meristem (SAM) that act to place auxin maxima at the future sites of leaf initiation. Inherent to this process is a bias in auxin distribution in leaf primordia, such that increased auxin is found on the descending side of the leaf (toward the older neighbor) compared to the ascending sid...

Abstract This study develops a new phenomenological constitutive model to capture the unique evolving cyclic elastoplastic behaviours of hexagonal close-packed (HCP) sheet metals. is developed by adopting concepts multiple-yield surface approaches. Four deformation modes, including Monotonic Compression (MC), Tension (MT), Reverse (RC), and (RT), are considered represent hardening evolution mat...
