Abstract:

The estimation of velocity macro‐models by seismic reflection tomography is studied in three‐dimensions. Inversion techniques based on the kinematics of seismic data require an appropriate parameterization of the geological macro‐model, in particular as far as the velocity field is concerned. The step toward structurally complex geological models is achieved by exploiting a new approach to 3-D depth modeling: GOCAD. The peculiarities inherent to GOCAD triangulated surfaces and its associated discrete smooth interpolator (DSI) have led to the development of original ray‐tracing techniques. By e

In the analysis of the GOCAD SGrid model and the FLAC3D hexahedral mesh model, a method of converting the former to the latter is proposed, and the data conversion program is prepared based on VB.NET. The purpose of building complex models in FLAC3D quickly is achieved, and the FLAC3D simplifies the pre-processing largely. Finally, the feasibility of the method is verified by a practical project.

Abstract:

An approach towards integrated modelling of 3D geology and landslide susceptibility was performed with the application of GOCAD and GIS. Rock unit outcrops and orientation vectors were utilised in 3D geological modelling (geomodelling) whereas landslides and their causative variables were evaluated in the susceptibility model. Occurrence of landslides in the modelling site is the direct result of major rainstorms (extreme weather events) and their spatial localisation is greatly controlled by slope gradients, structural aspect of geological settings, and human interventions.

Mapping of the Cnoc nan Cuilean intrusion shows two main zones: a Mixed Syenite Zone (MZ) and a Massive Leucosyenite Zone (LZ), with a gradational contact. The MZ forms a lopolith, with multiple syenitic lithologies, including early basic melasyenites and later felsic leucosyenites. Leucosyenite melts mixed and mingled with melas

Activated sludge is the most widely used process for wastewater treatment. However basic properties such as floc structure or settling properties, still remain unknown. In order to describe activated sludge floc structure, four investigation methods were used: (i) size distribution analysis associated with sonication, (ii) transmission electron microscopy (iii) laser scanning confocal microscopy and fractal dimension analysis, and (iv) three dimensional modelling. The evolution of floc size distribution in dispersed samples was used to build a model of floc showing that the predominating micro

Abstract:

One of the key challenges to assist in the understanding of the potential impacts of coal seam gas (CSG) extraction is the development of robust geological and numerical models. In the Clarence-Moreton Basin, this task is complicated by the need to integrate shallow alluvial aquifers (typically less than 30 m thick) and deep bedrock aquifers, which can have a combined thickness of up to approximately 3,500–4,000 m in some parts of the basin. While shallow aquifers are not typically considered in petroleum reservoir studies, they are of great significance in the Australian government’s Bioregio

Abstract:

Improved genome-editing via oviductal nucleic acid delivery (i-GONAD) is a technique capable of inducing genomic changes in preimplantation embryos (zygotes) present within the oviduct of a pregnant female. i-GONAD involves intraoviductal injection of a solution containing genome-editing components via a glass micropipette under a dissecting microscope, followed by in vivo electroporation using tweezer-type electrodes. i-GONAD does not involve ex vivo handling of embryos (isolation of zygotes, microinjection or electroporation of zygotes, and egg transfer of the treated embryos to the oviducts

Abstract:

The reproductive cycle of the saucer scallop Amusium balloti was examined at three sites spanning a large part of the north-south range of the species on the western coast of Western Australia. Variations in gonad dry weight were highly cyclical, with minimum gonad weights in Shark Bay (25�S) occurring between January and March and maximum gonad weights occurring around July or August. The pattern of variation in gonad weight at the Abrolhos Islands (29�S) and Fremantle (32�S) was similarly cyclical, but the times of high and low gonad weights occurred at similar times at both sites and approx

Anthropogenic activities that tend to be exploitative in the mangrove ecosystem of Belawan are thought to have an impact on the biota associated with the ecosystem. One of the impacts is thought to be implied by mantis shrimp Cloridopsis scorpio (Latreile, 1828). The reproductive biology of the shrimp is the main object that needs to be studied in relation to the impacts. This study aims to determine the distribution of gonad maturity stage, gonad somatic index, and the length of the first mature of C. scorpio in the Mangrove Ecosystem of Belawan, North Sumatera.

Seasonal variations in the gonad index and the biochemical composition of gonad and gut tissue of the sea urchin, Paracentrotus lividus (Echinodermata: Echinoidea) were determined. Samples were collected from Lorbé (Galicia, north-western Spain) between November 1994 and October 1995. The gametogenic cycle of the sea urchin was annual, with a long, single spawning period from May to August 1995. Most of the biochemical components in gonad showed clear seasonal variation, which was related to the gonad cycle. The main component was protein, which ranged between 36 and 60% of the dry weight, wit

Abstract:

The adult ovaries and testes contain several specialized somatic cell types that support the differentiation of germ cells into mature gametes. Each of these cell types arise from mesodermal cells that constitute the embryonic gonad. To explore the mechanisms governing the development and differentiation of these cells, we focus on the formation of the gonad during Drosophila development. Using markers for the precursors of the somatic cells of the gonad, we identify discrete steps in the development of the gonad. Our results suggest the existence of different populations of gonadal precursors

The Caenorhabditis elegans LIN-26 protein is required to specify and/or maintain the fates of all non-neuronal ectodermal cells. Here we show that lin-26 is expressed until the somatic gonad primordium stage in all cells of the somatic gonad, except in distal tip cells, and later in all uterine cells. To determine if lin-26 functions in the somatic gonad, we have generated gonad-specific lin-26 alleles obtained by integration of lin-26 promoter deletion derivatives into a lin-26 null mutant background. In this way, we rescued the lethal phenotype imparted by lin-26 null mutations and uncovered
