Liquefaction occurs in loose and saturated cohesionlesssoils subjected to strong ground motion caused by earthquakes,machine vibrations, ocean waves, blasting, etc. It is a source ofmajor damage to various types of structures. Under cyclic loadingthe pore water pressure in loose to medium dense, saturatedcohesionless soils increases and the effective stress decreases,leading to a degradation of the shear strength and of thestiffness. It appears as if some damage occurs in the material.Recently, ...

The importance of the early mother-child relationshipand the navigation of separation-individuation in toddlerhood haslong been recognized. This study explored these relationshipissues at the time of the "second individuation." Relationshipwith mother was examined as a predictor of late adolescentfunctioning in the areas of ego identity status, depression, andeating disturbances. 183 college students (114 females and 69males; mean age was 19.14) from two campuses completed a batteryof ...

Diarrhea, a serious outcome for patients, commonlyoccurs following institution of enteral feeding. One suggestedetiology for the problem is bacterial contamination of theenteral feeding solution. The purpose of this study was to extendprevious pilot research on the occurrence of bacterialcontamination and diarrhea in tube-fed ICU patients by comparingtwo enteral feeding protocols. The protocols compared were theroutine hospital protocol vs an aseptic protocol for thepreparation and maintenance o...

The climatic significance of Greenland is determined bytwo main facts: the thermal forcing of its ice sheet and itstopographic forcing near the middle of the North Atlantic stormtrack. The Greenland Ice Sheet boasts about 10 percent of theworlds freshwater and its melting contributes about 7 percent ofthe annual rise in global sea level.

The work described in this thesis describes stepstowards building a zeolite-membrane based photochemical assembly,which can be used for developing a hydrogen evolving artificialphotosynthetic system. We adopted the membrane system of naturalphotosynthesis in our artificial photosynthesis system toseparate photochemically generated redox species. Forphotochemical applications, membranes without any inter crystalpinholes and grain boundaries are preferred since these defectsintroduce non-shape sel...

It is common in geodetic and surveying networkadjustments to treat the rank deficient normal equations in a waythat produces zero variances for the so�Vcalled��control�� points. This is often done by placingconstraints on a minimum number of the unknown parameters,typically by assigning a zero variance to the a priori values ofthese parameters (coordinates). This approach may require thegeodetic engineer or analyst to make an arbitrary decision aboutwhich parameters to constrain, which may have ...

Organisms that produce many, small offspring generallyexhibit variable population size, owing to variation inproduction and survival of offspring. Using a life- historyapproach, we focused on ecological mechanisms underlying theproduction and survival of white crappie Pomoxis annularis, apopular North American sport fish exhibiting high variability inrecruitment to maturity (i.e., age-2). Offspring productionbegins with adult energy allocation to reproduction. Female whitecrappies initiate ovary...

Genomics offers new perspectives for the discovery ofnovel genes in the oomycetes, a unique group of eukaryoticmicrobes comprising saprophytes as well as pathogens of plantsand animals. Among the oomycetes, the most devastating plantpathogen is the potato and tomato late blight pathogenPhytophthora infestans. Currently tens of thousands of expressed sequence tags (ESTs)are available forP. infestans. The challenge of the post-genomic era is to link a sequence toa phenotype (functional genomics) w...

Carbonate buildups are a common facies in Middle andLate Paleozoic shelf and slope deposits worldwide. This facies,in general, has been the focus of numerous studies becausebuildups, as reef analogues, can provide a wealth ofpaleoenvironmental, paleobiological, and sedimentologicalinformation. Additionally, since carbonate buildups often serveas traps for petroleum, understanding their temporal and spatialdistribution as well as the dynamics associated with theirdeposition can be an economically...

Studies of modern storm processes indicate thatpost-mortem transport of benthic marine organisms is oftennegligible, suggesting that subfossil death assemblages maycommonly preserve spatial community structure with good fidelity,albeit time-averaged. To test the implication that the samefidelity is to be expected in ancient assemblages, the UpperOrdovician strata of the type Cincinnatian provide highlyfossiliferous, laterally extensive outcrops that are ideallysuited for assessing fine-scale spa...

This research discusses a solution to detection andavoidance of simulated potholes in the path of an autonomousvehicle operating in an unstructured environment. Potholeavoidance may be considered similar to other obstacle avoidanceexcept that the potholes are depressions rather than extrusionsfrom a surface. Simulated potholes were used in this research. Avision approach was used since the simulated potholes weresignificantly different visually from the background surface.Large potholes more tha...

Although oxygen isotopes have been widely used inpaleotemperature estimation, knowledge of Archean seawatertemperatures remains limited. It is widely documented that �_18O values in carbonates, phosphorites, and cherts are moredepleted with increasing age, a pattern due either to primarychanges in seawater �_18O or temperature, or to secondary alteration. Samples of theCarawine Dolomite, of late Archean age (2.5 Ga) of westernAustralia were analyzed with the goal of constraining Archeanseawater ...

Successions of carbonate to mixedcarbonate/siliciclastic rocks of Middle Ordovician age weredeposited in New York State and Ontario, Canada on the passiveedge of the westward advancing Taconic foreland basin. Thetransition from carbonate to siliciclastic sedimentation isthought to record the critical change from a passive to activetectonic margin. In addition to tectonic change, it has beensuggested that this stratigraphic interval also records anoverall transgressive series (Tippecanoe megasequ...

This dissertation presents a method to extract features salient to a mobile robot navigation task in a specific environment. The extraction process is bootstrapped by a human operators tele-operation and is based on the sensory-motor coordination principle.
