Scavenger-Predator-Prey Model with Finite Resources
… each delving into the dynamics of predator-prey-scavenger interactions. The first segment of the thesis investigates the role of predator-taxis in pattern formation within predator-prey systems, as documented in the paper ”Generalized Holling III Functional Response: role of predator-taxis on …

A hybrid scavenger grid approach to intranet search
… may not be economically viable. A hybrid scavenger grid is proposed as an alternative architecture - it consists of a combination of dedicated and dynamic resources in the form of idle desktop workstations. From the dedicated resources, the architecture gets predictability and reliability …

Piezoelectric Micro Power Generator (PMPG) : a MEMS-based energy scavenger
As MEMS and smart material technologies begin to mature, their applications, such as medical implants and wireless communications are becoming more attractive. Traditionally, remote devices have used chemical batteries to supply their energy. However, batteries are no longer suitable for many of …

Role of scavenger receptor MARCO in particle uptake and lung inflammation
… the role of membrane glycoproteins called scavenger receptors in binding of environmental particles. The scavenger receptors are classified into different classes (A-H) based on their structure and function. Class A scavenger receptors are critical in uptake of variety of ligands such as …

The evolution of mating systems in black scavenger flies (Diptera: Sepsidae)
Black scavenger flies are characterized by sexual behaviours that are very unusual in insects. I have studied two of the most remarkable elements of their mating systems: the timing of copulations immediately after an oviposition bout (post-oviposition matings) and the males' escorting of …

The role of scavenger receptor B-I in hepatitis C virus attachment and entry.
… on at least three cellular entry factors: CD81, Scavenger Receptor B-I (SR-BI) and Claudin-1. SR-BI is a receptor for high density lipoprotein (HDL), it is predominantly expressed in the liver and steroidogenic tissue. HCV is believed to interact with SR-BI via the viral envelope protein E2, …

UNCOVERING THE EVOLUTION AND DEVELOPMENT OF A NOVEL ABDOMINAL APPENDAGE IN BLACK SCAVENGER FLIES (SEPSIDAE: DIPTERA)
I explore the evolution and development of a novelty in sepsid flies where males have recently evolved an elaborate brush-like appendage on the fourth abdominal segment that varies in shape and size across the family. A comparative analysis showed that male sepsids pay for more ornate 4th sternite …

Formaldehyde-MEA Triazine Based Hydrogen Sulfide Scavenger Behavior Study and Applications in the Oil and Gas Industry
… Triazine is one of the common H2S scavengers in use. The objective of this research was to review different chemistries and field applications applicable as H2S scavengers in oil and gas, understand the Formaldehyde-MEA Triazine’s properties and behaviors in the sweetening process, …

Effekte des oxidativen Stresses auf die Expression der Scavenger-Rezeptoren CD36 und SR-BI und des Transkriptionsfaktors PPARγ in Makrophagen
… von oxLDL auf die Expression der atherogenen Scavenger-Rezeptoren CD36, SR-BI, des Transkriptionsfaktors PPARγ und pro-inflammatorischer Zytokine zu untersuchen. Die durchgeführten Untersuchungen beruhen auf der Annahme, dass modifizierte LDL durch Induktion der genannten Scavenger-Rezeptoren …

Crayfish: Scavenger or deadly predator? Examining a potential predator-prey relationship between crayfish and benthic fish in aquatic food webs
Benthic food webs are complex and often poorly understood. Crayfish in particular play a key role in the transfer of energy to higher trophic levels, and can constitute the highest proportion of benthic invertebrate biomass in an aquatic system. Commonly referred to as a keystone species, crayfish …

Tissue specific regulation of the high density lipoprotein (HDL) receptor, scavenger receptor Class B, Type I (SR-BI) by the scaffold protein PDZK1
PDZK1 is a four PDZ-domain containing cytoplasmic adaptor protein that binds the Cterminus of the high-density lipoprotein (HDL) receptor SR-BI. Abolishing PDZK1 expression in PDZK1 knockout (KO) mice leads to a post-transcriptional, tissue-specific decrease in SR-BI protein level and an increase …
