Abstract: The demands for organically produced vegetable are increasing all over the world including Kuwait. Therefore, efforts are being made to develop an appropriate package of practices for organic greenhouse vegetable production under Kuwait's harsh climatic conditions. Several experiments were conducted to select suitable growing substrate for production of organic leafy vegetables like I...

SEQUENCE ORIGIN: Small RNA molecule U6 was isolated from the total cellular RNA of vegetative Phvsarnm microplasmodia (1) by preparative polyacrylamide electroshoresis (2,3). The molecule was radiolabeled in vitro to high-specific-activity using [ T>)-pCp and RNA-ligase, and sequenced by direct chemical methods as we previously described (3). In this sequencing process, pseudouridine scores as ...

Different models driven by remotely sensed vegetation indexes (VIs) and incident photosynthetically active radiation (PAR) were developed to estimate gross primary production (GPP) in a subalpine grassland equipped with an eddy covariance flux tower. Hyperspectral reflectance was collected using an automatic system designed for high temporal frequency acquisitions for three consecutive years, i...

Use of life-sustaining or invasive interventions in patients in a persistent vegetative state or who are terminally ill may only prolong the dying process. What constitutes futile intervention remains a point of controversy in the medical literature and in clinical practice. In clinical practice, controversy arises when the patient or proxy and the physician have discrepant values or goals of c...

Soviet Lysenkoism was the darkest period of modern science, and its main product — Michurinist biology — was a collection of absurd theories usually based on anecdotal observations or on a few badly designed experiments without proper controls and without any statistical evaluation of results. However, in the thirties and early forties, Lysenkoists also described (and misinterpreted) some inter...

Impervious surfaces (IS) are a key indicator of environmental quality, and mapping of urban IS is important for a wide range of applications including hydrological modelling, water management, urban and environmental planning and urban climate studies. This paper addresses the accuracy and applicability of vegetation indices (VI), from Landsat imagery, to estimate IS fractions for European citi...

Vegetation was added to a fully-developed sandy point bar in the meander of a 5 constructed stream. Significant changes in the flow structure and bed topography were observed. 6 As expected, the addition of vegetative resistance decreased the depth-averaged streamwise 7 velocity over the bar and increased it in the open region. In addition, the secondary circulation 8 increased in strength, but...

Herbaceous weed control (HWC) is prescribed for growing season control of vegetative competition in hardwood afforestation attempts on former agricultural areas. Without HWC, planted seedlings often exhibit poor growth and survival. While currently employed HWC methods are proven, there is a substantial void in research comparing HWC treatments spanning multiple years. A total of 4,320 bare-roo...
