Scavenging is the consumption of carrion by living organisms. Often overlooked, it is common in all ecosystems. The assemblage of scavengers that act on carrion are important in maintaining this ecosystem service and are part of the necrobiome. Scavengers can be classified into distinct guilds comprised of vertebrates, invertebrates, and microorganisms whose collaborative roles operate efficiently when their community structure is diverse and intact. The goal of this thesis is to quantify how scavenger guilds can influence decay rates and how insect scavengers respond to the absence of competi

The structural, microstructural and electrical characterization of these samples confirmed the formation of one apatite-type lanthanum silicate-based phase and a significant enhancement of the grain boundary conductivity of these materials.

The aerosol removal has a fundamental role because aerosol has impact on human health, on visibility and act as a condensation center for cloud droplets and ice crystals, changing cloud properties (indirect e�ects on cli- mate).

In recent years, there has been recent increase in the deployment of wireless sensor networks. These sensors are typically powered by a battery which has limited life span. This problem can be overcomed by using energy scavenging or power harvesting which is the process of converting ambient energy from the environment into usable electrical energy. It can be used in applications such as remote patient monitoring, implantable sensors, machinery/equipment monitoring and so on.

Pyroelectric energy scavenging is the process of converting wasted energy from a system to power another one, based on the pyroelectric effect of piezoelectric materials. Pyroelectrically generated power is a function of the surface of material, the pyroelectric coefficient, and the temporal temperature gradient. In the current project, a simple model is developed to predict the power generation based on the temporal change in temperature of material. In addition, a model is validated with experimental measurements from several piezoelectric materials. It is shown that energy generation can be

Thermal scavenging is a unique behavior restricted to a few desert ant genera. Workers are among the most thermotolerant land animals known to this day, being able to survive body temperatures of sometimes more than 50°C for several minutes. Making use of their remarkable heat-hardiness, they search for food in plain day, a feat that other desert creatures cannot accomplish. They mostly feed on the corpses of heat-stricken, less tolerant arthropods that were unable to survive the blazing sun of the midday desert.

The effects of aerosol in the atmosphere account for some of the largest uncertainties in estimates of the human impact on climate. These effects depend not only on the total mass of aerosol, but also its size distribution, mixing state and vertical profile. Previous studies have suggested that both the size distribution and mixing state of aerosol may be strongly influenced by repeated cycling through non-precipitating cloud. The extent of this process is assessed in the HadGEM3–UKCA model; although fewer cycles are seen for all aerosol than in previous studies, the figure varies considerably

Resumo:

In biological systems, iron is extremely important due to its use in electron transport, redox centers, oxygen transport, dismutation of reactive oxygen species, and structural stabilization. Among bacteria, iron is essential for healthy growth and many mechanisms exist for its acquisition. A prominent example is the iron-regulated surface determinant (Isd) system, which is found in many pathogens including the causative agent of anthrax, Bacillus anthracis. In the Isd system of B. anthracis, the protein IsdX1 is responsible for scavenging heme from host hemoglobin so that iron can be acquired

Resumo:

Most current space robotics vehicles use solar energy as their prime energy source. In spherical robotic vehicles the use of solar cells is very restricted. Focusing on the particular problem, an improved method to generate electrical power will be developed; the innovation is the use of an internal pendulum-generator mechanism to generate electrical power while the ball is rolling. This concept will enable spherical robots on future long-duration planetary exploration missions. Through a developed proof-of-concept prototype, inspired by the Russian thistle plant, or tumbleweed, this thesis wi
