Ca2+ dependant synaptic modification
It has been assumed that Ca2+ influx of different duration and amplitude would generate different level of potentiation. The conventional protocols of generating LTP have been 1. tetanic stimulation of presynaptic cell, 2. theta burst stimulation of presynaptic cell, and 3. correlated stimulation …

Time dependant redundancy optimization
Three different time-dependent optimal reliability design models with a series-parallel system are formulated. An efficient heuristic procedure for each problem is elucidated, and the results are described. The redundancy optimization problem using the time-dependent reliability function is solved …

Automatic Dependant Surveillance-Broadcast Training
According to the Federal Aviation Administration (FAA), current delays in air traffic across the United States cost the country’s economy roughly 9.4 billion dollars annually. With air traffic expected to triple again over the next several decades, the FAA has been in the process of implementing …

Stretch-Dependant Tonic Force Maintenance in Rabbit Epigastric Artery
The contractile state of vascular smooth muscle (VSM) plays a key role in blood pressure regulation. Abnormal VSM contractility characterizes hypertension and understanding the regulatory mechanisms of VSM may provide some insights to specific treatment of hypertension. Upon muscle stimulation, …

Substrate dependant survivorship of Ecklonia maxima, in southern African kelp communities
Several south-western Cape Ecklonia maxima communities were examined to determine their basic demography and the effects of substrate selection. Overall percentage substrate composition, stipe lengths and substrate attachment for all kelps were recorded at four sites off the Cape Peninsula. …

Characterization and localization of a cyclic AMP dependant protein kinase from Dictyostelium discoideum
A developmentally regulated cyclic AMP-dependent protein kinase has been recently reported in Dictyostelium discoideum. This report describes some of the physical and kinetic properties of the cAMP-dependent holoenzyme and its subunits. Gel filtration data suggests a holoenzyme Mr of …

An analytical model of MAC protocol dependant power consumption in multi-hop ad hoc wireless sensor networks
Power efficiency is the most constraining requirement for viable operation of battery-powered networked sensors. Conventionally, dynamic power management (DPM) is used to put sensor nodes into different states such as active, idle, and sleep, each consuming a certain level of power. Within the …

Examination of 2-Oxoglutarate Dependant Dioxygenases Leading to the Production of Flavonols in <i>Arabidopsis thaliana</i>
… activities in animals. The 2-oxoglutarate-dependant dioxygenases(2-ODDs), flavonol synthase (FLS) and flavanone 3-hydroxylase (F3H), are essential for flavonol synthesis. The primary goal of this study has been to gain a deeper understanding of the biochemistry of these enzymes in …

MECHANICAL ABRASION AND ELECTROPORATION IN THE TRANSFORMATION OF INTACT PLEUROTUS OSTREATUS HYPHÆ and NUTRIENT-DEPENDANT RESISTANCE TO HYGROMYCIN B
<p>ABSTRACT 1: Abrasive treatment and subsequent electroporation of the basidiomycete Pleurotus ostreatus in a hypertonic buffer was investigated as a potential method of transforming of intact hyphæ. Mycelia, which are not capable of being transformed via electroporation due to interference by the …

Identification of Candidate Effector Proteins from Fusarium graminearum during Infection of Arabidopsis thaliana Using Proximity-Dependant Biotin Identification (BioID)
Fusarium graminearumis a fungal pathogen that causes Fusarium head blight (FHB) in cereal crops. Identifying proteins that are secreted from pathogens to overcome plant defenses and cause disease, collectively known as effectors, can reveal new targets for fungicides or other control …

Analytical behaviour of FRP strengthened reinforced concrete beams under low velocity impact load incorporating rate dependant material constitutive models
Since the 1980s, the use of fibre reinforced polymer (FRP) composites in strengthening and rehabilitation of existing reinforced and pre-stressed structures has gained popularity. Versatility, high strength to weight ratio, corrosion resistance, excellent creep and fatigue behaviour, and ease of …

Characterizing the Role of Gds1p in the Saccharomyces cerevisiae Environmental Stress Response
… target of NuA4. Gds1 protein level is dependant both on NuA4 and environmental stress and our analysis shows it to be involved in the nuclear exclusion of Msn2p in the absence of stress. Unstressed cells lacking GDS1 exhibit increased nuclear accumulation Msn2p and an increase in …

Novel hydrogel polymers
… The sequence distribution was found to be dependant on the structure and reactivity of the monomers. The EWC was found to be dependant on the water structuring groups present in the hydrogel, although the water binding abilities were modified by steric effects. The mechanical properties …

Vegetation survey of Namibia: conceptualisation and implementation of a nation-wide vegetation survey serving practical land management needs
The global human population is dependant on a variety of plant-based ecosystem services for its well-being, even for its very existence. The well-being, in fact, the very existence of man is dependant upon plant-based ecosystem services. Typical services derived from ecosystems encompass food …

The effect of applied fields on crystallisation
… hydrates. The resulting sucrose crystals were dependant on the type of field applied, the purity of the sucrose solution and the residence time within the applied field. The lactose study under static conditions provided similar results concluding that applied fields resulted in a more …
