Abstract:
Heritage monuments across the world are affected by a variety of physical and biological stresses. Damage to heritage monuments due to insects and pests is growing with increasing anthropogenic pressure and changing climatic conditions. Cave monuments are habitats to microbes, algae, fungi, and insects, and are unique biodiversity sites due to their low temperature, little to no sunlight, and high moisture conditions. This study takes stock of available information on important factors that facilitate the growth of insect pests and degrade heritage monuments. Ajanta Caves, a UNESCO world herit

Abstract:
This thesis concentrates on evolutionary costs and benefits of insect parental care. I use phylogenetic methods to test large-scale hypotheses, and field studies to test proximate hypotheses. Initially I look at the evolution of variation in the sex performing care, reconstructing transitions across insect evolutionary history. Consistent with theory, early insects had no care, and their descendants evolved either male care, or female care followed sometimes by biparental care. Secondly, I investigate parental care trade-offs. I find that in insects, care is associated positively with offsprin

It is well known that milling is a rotating and interrupted cutting process in which the milling cutter is made up of a number of inserts placed around its body and that each insert has the function of removing an amount of material from the workpiece per revolution.

Abstract:
Abstract Laser powder bed fusion (L-PBF) can make injection molding tools with conformal cooling channels that can reduce plastic part warpage and production cycle times. In this study, we define the design space in which L-PBF tools are economically and environmentally beneficial compared to traditional toolmaking methods. We develop mechanistic production cost, lead time, and cradle-to-grave life cycle assessment models of the cumulative energy demand (CED) and greenhouse gas (GHG) emissions associated with injection molding (IM) tool inserts made from tool steel using a Renishaw AM500Q L-PB

The ecological approach to the maintenance and care of perennial fruit plantations is being applied more and more. In agriculture, biological control of plant diseases and pests is one of the key measures for organic food production. Apple is the most commonly grown fruit species in Serbia. For the production of quality fruits, it is necessary, in addition to regular maintenance, to control pests in the orchard. Damage to apples is caused by several types of insects, the most important of which are: Cydia pomonella, Aphis pomi, Eriosoma lanigerum, Tropinota hirta, Anthonomus pomorum. Larvae an

Abstract:
This paper presents a case study examining the utility of design exemplar technology as a search and retrieval tool with respect to retrieving mold inserts for a tire manufacturing company. Limitations of using the geometric-based exemplar approach such as tediousness of authoring exemplars and time complexity are identified. These limitations are addressed by developing a new parametric-based exemplar approach. This approach calculates a set of maxima and minima based on the specifications of the query mold insert. The design exemplar is essentially useful to prototype the query mechanism. Ho

In order to improve the manufacturing efficiency and product quality of transparent and complex plastic knobs, a hot runner injection mold is introduced in this paper. Based on a shared hot runner system and a module combination of the mold holders, inserts and the beryllium-copper cored cooling components, an effective general model for hot runner injection molding is developed. The beryllium copper insert extrusion process is employed to copy with the requirements of great variety, high quality, low price and short producing cycle for knob products.

Abstract:
A major consideration in the development of biopesticides based on entomopathogenic fungi has been the virulence and pathogenicity in terms of mean time of mortality and mean lethal concentration against the target insect. Virulence factors as chitinases degrade insect chitin facilitating the hyphal penetration through the cuticle. In this sense, Beauveria bassiana chitinases are an important cuticle-degrading group of enzymes implicated in the pathogenesis to insects, with high potential to develop biotechnological tools for in pest control. The aim of this study was to characterize chitinase

Abstract:
Animal-associated microbiomes are critical to the well-being and proper functioning of the animal host, but only limited studies have examined in-sect microbiomes across different developmental stages. These studies revealed large shifts in microbiome communities, often because of significant shifts in diet during insects’ life cycle. Establishing insect colonies as model laboratory organisms and understanding how to properly feed and care for animals with complex and dynamic life cycles requires improved data. This study examined laboratory raised green June beetles (Cotinis nitida) captured

Abstract:
Viral haemorrhagic fevers (VHFs) are a group of severe illnesses caused by viruses that affect multiple organ systems and damage the cardiovascular system. VHFs include Ebola virus disease and Marburg virus disease. There is wide variation in how VHFs are diagnosed, how pathogenic they are, their geographic distribution, their known reservoirs (i.e., animals or insects that spread the disease) and the availability of vaccines or treatments. When using this Question Bank for a specific public health emergency in connection with an identified VHF, consider these factors in addition to an updated

Genetic and biochemical analysis of glucosinolate breakdown: The effects of indole-3-carbinol on plant physiology and development Glucosinolates are a class of defense-related secondary metabolites found in all crucifers, including important oilseed and vegetable crops in the Brassica genus and the well-studied model plant Arabidopsis thaliana. Upon tissue damage, such as that provided by insect feeding, glucosinolates are subjected to catalysis and spontaneous degradation to form a variety of breakdown products. These breakdown products typically have a deterrent effect on generalist herbivor

In conducting this research, we explored all combinations of tetraploid and diploid parents, in reciprocal combinations.
