Rapid Model Import Tool (RMIT)

Our project is about developing a tool to implement conversion of 3D Computer Aided Design (CAD) models produced with software such as Delmia, 3DS Max, or Maya, into a size and format compatible with the Unity 3D environment. RMIT will be used to aid KSC engineering personnel in the design, development, testing, operations, and training on spacecraft, launch vehicles, facilities, and ground support equipment. For our project, we are using Blender, a free/open-source 3D graphics software, with the goal of developing, testing, and deploying a 3D CAD model converter tool. I worked on using Blender to import 3D CAD models exported from CATIA software into Collada file format. The Collada file format has file extension DAE. Importing the Collada DAE file as is into Blender, generates dots and dashes. In 3DS Max, there is an existing OpenCollada plugin and with that plugin, 3DS Max can import the DAE file successfully. But, Blender does not seem to have an OpenCollada plugin, so I worked on writing a new OpenCollada plugin for Blender. Since 3DS Max was able to display the image, I looked into comparing differences between the original DAE file and the DAE file exported from 3DS Max using the OpenCollada plugin. As Collada documents describing digital assets are XML files with file extension DAE, Collada files contains XML tags, making them easily modifiable. After some research, it appears that Blender does not like primitive 2D tags like tristrips and trifans. Changing those tags to polygons slightly improved the image, but the pieces were exploded. I found after further research comparing differences between the original file and the file exported from 3DS Max that the values inside the translate tags in the original file are scaled down by a factor of 25.4 in the exported file from 3DS Max, representing the millimeters to inches conversion (1 inch = 25.4 millimeters). After scaling down values inside all of the translate tags by 25.4, the exploded pieces stuck back in, but the image needed further improvement. I have been able to create a new plugin in Blender that takes the original DAE file, replaces the primitive 2D tags tristrips and trifans with polygons, scales down the values inside the translate tags by a factor of 25.4, and saves the changes into a temporary DAE file. After the temporary DAE file is imported into Blender, the temp file is then deleted, keeping the original DAE file intact. Starting with a DAE file that is exported using the NASA Enterprise Visualization Application (NEVA), a Collada exporter, from CATIA gives better results. NEVA is a Design Visualization product that is used for exporting 3D models from CATIA. With NEVA, the up axis is defined in the top-level node if navigation gravity is enabled. With that file, just replacing the primitive tags tristrips and trifans with polygons in yields a much improved image in Blender. As we identify more differences between the original DAE file and the DAE file exported from 3DS Max, this plugin can be improved further. Our goal is to have a model that is formatted and sized for import into Unity, and we are trying out different 3D programs to see which will work best

Certain abnormalities in millets induced by X-rays

1. Some of the recessive abnormalities induced by X-rays in E. coracana Gaertn. and Pennisetum typhoides S. & H. are described. 2. In E. coracana are described a chlorophyll deficiency in which the first two or three leaves are green and white banded, but the mature plant is fully green and two mutations effecting the panicle. In P. typhoides have been noted gappiness, tip-sterility, forking and goose-necking in the panicle, male-sterility, and weak-midribbed leaves all behaving as recessives. 3. While some of the plant characters in both these millets mutated easily, others showed no tendency to mutate. Thus in E. coracana the panicle shapes and chlorophyll factors mutated while the grain colour, length of glume and growth factors did not give any mutations, while in P. typhoides the greatest number of mutations were observed in the chlorophyll and panicle characters. 4. P.typhoides threw out more mutations than E. coracana and this is adduced to the diploidy of the former and the tetraploidy of the latter

Intending the Unintended: The Act of Building Agent-based Models as a Regular Source of Knowledge Generation

Poverty is a complex issue that is rarely conducive to analysis in laboratory or field experiments. Effective interventions that aim to decrease or eliminate poverty require an understanding of the intricate web of associated social issues. The need for this increased comprehension necessitates the use of alternative robust means of analysis: one such being agent-based modelling. The strengths of agent-based modelling to disaggregate complex social behaviours and understand them are well known. However, while people have explored how the modelling process can prove to be fruitful, the usually unintended insight gained and the knowledge engendered during the model design process goes largely unnoticed. In this paper, we aspire to show precisely how the model building process is critical in leading to unintended knowledge generation for modellers by drawing from three US based examples where agent-based modelling was used to aid research into the effects of interventions that address poverty and human development through programs and issues facing low-income families. With these examples, we illustrate some of the means to harness new knowledge generated. In our discussion, we also highlight the advantageous nature of agent-based model design as an independent source of knowledge generation

Improved synthesis of [ 11 C]methylaminobenzovesamicol

An efficient two‐step synthesis of the potential cholinergic neuronal mapping tracer [ 11 C]methylaminobenzovesamicol (MABV) is described. A tert ‐butoxycarbonyl protecting group was used to activate the aniline nitrogen of aminobenzovesamicol toward [ 11 C]methyl iodide methylation under basic conditions. Following labeling, the protecting group was removed by brief acid treatment and the final product was purified by normal phase HPLC. The decay corrected yields of MABV are in the range of 30‐70 %, based on 11 CO 2 , with a specific activity of 0.5‐1.5 Ci/ μmol and synthesis time of less than 45 minutes. This new route makes clinical scale doses of this interesting compound available for human positron emission tomography studies.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/90085/1/2580310402_ftp.pd

Modeling of the Aniline with Nitrobenzene Reaction by PM6 Method

Modeling of the aniline with nitrobenzene reaction was carried out by PM6 method with tetramethylammonium hydroxide. Calculated data prove that the stage of transfer of hydride ion from the p-[sigma]-complex to the acceptor, i.e. nitrobenzene or 4- nitrodiphenylamine determines the rate of aniline with nitrobenzene condensation. Herein, intermolecular transfer mechanism that has lower activation energy is the most likely one if compared with intramolecular mechanism. It is shown that tetramethylammonium cation can form ionic and ion-dipole complexes with the components of the reaction mixture and its field influences the distribution of electron density in the reactants and their reactivity

Unraveling the ECM-Immune Cell Crosstalk in Skin Diseases

The extracellular matrix (ECM) is a complex network of proteins and proteoglycans secreted by keratinocytes, fibroblasts and immune cells. The function of the skin ECM has expanded from being a scaffold that provides structural integrity, to a more dynamic entity that is constantly remodeled to maintain tissue homeostasis. The ECM functions as ligands for cell surface receptors such as integrins, dystroglycans, and toll-like receptors (TLRs) and regulate cellular signaling and immune cell dynamics. The ECM also acts as a sink for growth factors and cytokines, providing critical cues during epithelial morphogenesis. Dysregulation in the organization and deposition of ECMs lead to a plethora of pathophysiological conditions that are exacerbated by aberrant ECM-immune cell interactions. In this review, we focus on the interplay between ECM and immune cells in the context of skin diseases and also discuss state of the art therapies that target the key molecular players involved
