BACKGROUND AND AIMS Submergence is a recurring problem in the rice-producing rainfed lowlands of south and south-east Asia. Developing rice cultivars with tolerance of submergence and with agronomic and quality traits acceptable to farmers is a feasible approach to address this problem. The objectives of this study were to (a) develop mega varieties with Sub1 introgression that are submergence ...

This paper presented the findings of an experimental investigation into how common Portland cement concrete develops its compressive strength in a simple setting, such as Lahore, Pakistan. Ten cube specimens mix 1:1.5:3 was prepared with water-cement ratio 0.5 for each four curing techniques (air curing, water-submerged polythene by boiling) until testing ages 3, 7, 14, 21 and 28 days when thei...

Partial submergence of Oryza sativa deepwater rice elicits enhancement internodal elongation, referred to as response, conferred by three types genes, SNORKEL1/2 (SK1/2), SEMIDWARF1 (SD1), and ACCELERATOR OF INTERNODE ELONGATION 1 (ACE1). We investigated the presence expression these genes in African cultivated glaberrima relationship between response O. glaberrima. In 49 50 accessions tested, ...

The acronym CHARGE refers to a non-random clustering of congenital malformations whose cause remains unknown. To date, the dental features of CHARGE association are not well known. A brief review of the literature and a case in a 10-year old boy with the CHARGE association are presented. The patient had multiple dental anomalies including congenital absence of teeth, ectopic eruption, submergen...

Submerged tooth is the one that is depressed below the occlusal plane. Dental ankylosis is thought to be a major cause of submergence. Submerged deciduous teeth have the potential to cause malocclusion not only by prevention of their exfoliation and subsequent replacement by permanent teeth but also by causing tilting of proximal teeth and extrusion of opposing tooth. The purpose of this report...

Vortical flow formed by a submerged hydraulic jump may produce significant hydrodynamic lift and drag pressures on gate beneath the jump. In this study, an experimental setup equipped with multi-pressure sensors was used to measure fluctuating impact for different conditions characterized inlet Froude number submergence factor (S). Time-averaged instantaneous pressure coefficients are evaluated...
