Weedy rice (Oryza sativa L.) is one of the major issues of rice cultivation worldwide. In Italy, it infests about 70% of the total rice area. Different Weedy Rice populations can be distinguished based on variable morphological and physiological traits; however, little is known about genetic differentiation and origin of Italian weedy rice populations. The objective of this study was to genetic...

Common wild rice (Oryza rufipogon), the wild relative of Asian cultivated rice (Oryza sativa), flaunts long, barbed awns, which are necessary for efficient propagation and dissemination of seeds. By contrast, O. sativa cultivars have been selected to be awnless or to harbor short, barbless awns, which facilitate seed processing and storage. The transition from long, barbed awns to short, barble...

department of Medicine in the Medical College of the University for one academic year. My first misgivings about the organisation I was to join came from the e*tremely vague and unbusinesslike way in which I | ^as called to this task, and from the obvious sense of fuddle which surrounded my appointment both before | arid after arrival. However, travel arrangements went smoothly and I was soon d...

Soil salinization requires developing genetically salt-tolerant and high-yielding genotypes, especially in semi-arid arid regions. In this study, two new Tunisian durum wheat cultivars, INRAT100 Dhahbi, were tested for the first time a semi-closed environment against salinity (0, 6 12 dS m-1). Dry weight of aerial root parts, plant height, number tillers per plant, spike awn length, grain yield...

BACKGROUND Many studies have emphasized on fetal pinna measurements and morphologic features to use this structure as an additional marker for fetal chromosomal anomaly. OBJECTIVES To assess relationship between fetal pinna length and gestation age and develop a nomogram. To assess relationship between fetal pinna length and head circumference and biparietal diameter. METHODS Fetal pinna me...

data collected in 2012 on 400 chickens were subjected to two-way analyses of variance to estimatebody weight, morphometric traits as well as the correlationbetween body weight and morphometric traitsin isa brown and ilorin ecotypechickens. the studied morphometric traits were comb length, beak length,head length, neck length, body length, wing length, shank length, thigh length, toe length, bre...

Injecting weight noise during training has been proposed for almost two decades as a simple technique to improve fault tolerance and generalization of a multilayer perceptron (MLP). However, little has been done regarding their convergence behaviors. Therefore, we presents in this paper the convergence proofs of two of these algorithms for MLPs. One is based on combining injecting multiplicativ...

Myosin Va (myoV) is a processive molecular motor that transports intracellular cargo along actin tracks with each head taking multiple 72-nm hand-over-hand steps. This stepping behavior was observed with a constitutively active, truncated myoV, in which the autoinhibitory interactions between the globular tail and motor domains (i.e., heads) that regulate the full-length molecule no longer exis...

This is a PDF file of an unedited manuscript that has been accepted for publication. As a service to our customers we are providing this early version of the manuscript. The manuscript will undergo copyediting, typesetting, and review of the resulting proof before it is published in its final form.
