Title of Document: RELIABILITY ASSESSMENT OF VOIDED MICROVIAS IN HIGH DENSITY INTERCONNECT PRINTED CIRCUIT BOARDS UNDER THERMO MECHANICAL STRESSES Roozbeh Bakhshi, Master of Science, 2013 Directed By: Professor Michael Pecht, Department of Mechanical Engineering Microvias allow signal and power transmission between layers in high density interconnection printed circuit boards. Presence of voidi...

Quanti-qualitative changes in Dinophysis and Alexatidrium populations from the Gulf of Venice NW Adriatic Sea were studied on a short time scale (44 h cycles). Under hydrographic conditions of marked thermo-haline stratification (July 1995), D. sacculus populations assembled in the surface waters (12 24 yt isopycnals). Division processes took place mostly in the early hours of the morning and a...

Two hardwood species, namely red oak and yellow-poplar, were separated into their bark, sapwood and heartwood components. The samples were tested for calorific value, specific gravity, proximate analysis, mineral composition, chemical composition, ultimate analysis, and thermo-chemical decomposition behavior. In addition, the thermo-chemical decomposition behaviors of cellulose, xylan, and lign...

Alpha amylase family is generally defined as a group of enzymes that can hydrolyse and transglycosylase α-(1, 4) or α-(1, 6) glycosidic bonds along with the preservation of anomeric configuration. For the comparative analysis of alpha amylase family, nucleotide sequences of seven thermo stable organisms of Kingdom Archea i.e. Pyrococcus furiosus (100-105°C), Kingdom Prokaryotes i.e. Bacillus li...

A new monolithic solution scheme for thermo-elasto-plasticity and thermo-elasto-plastic frictional contact with finite deformations and finite strains is presented. A key feature is the reformulation of all involved inequality constraints, namely those of Hill’s orthotropic yield criterion as well as the normal and tangential contact constraints, in terms of non-smooth nonlinear complementarity...

A thermo-anemometric flowmeter design and the principles of its work are presented in the article. A mathematical model of the temperature field in a stream of biofuel is proposed. This model allows one to determine the fuel consumption with high accuracy. Numerical modeling of the heater heat balance in the fuel flow of a thermo-anemometric flowmeter is conducted and the results are analyzed. ...

Injectable Hydrogels In article number 2101284 by Chien-Chi Lin and co-workers, a biocompatible pH/thermo dual responsive injectable hydrogel is synthesized reversible addition-fragmentation chain-transfer (RAFT) polymerization acylhdrazone click chemistry. Upon injection, sol-gel transition occurs rapidly at body temperature the porous hydrogels degrade slowly under mild acidic condition due t...

Aflatoxins, a group of extremely hazardous compounds because of their genotoxicity and carcinogenicity to human and animals, are commonly found in many tropical and subtropical regions. Ultraviolet (UV) irradiation is proven to be an effective method to reduce or detoxify aflatoxins. However, the degradation products of aflatoxins under UV irradiation and their safety or toxicity have not been ...

A thermo-sensitive imprinted polymer coating CdTe quantum dots was developed to prepare fluorescent thermo-sensitive protein-affinity materials, which exhibited high specific recognition ability towards target proteins.

We established the Arctic System Science/Thermokarst (ARCSS/TK) project in 2008 with the intent to use a systems approach to address hypotheses about how upland thermo-erosional features influence the structure and function of the foothill and mountainous landscape in the vicinity of the Brooks Range in arctic Alaska. We found that the common thermo-erosional features in this region are thaw sl...
