The features of constructing a geostatic model (GSM) of the Akshabulak productive horizon in the composition of oil-saturated reservoirs Yu-0-0, Yu-0-1, Yu-0-2 and Yu-0-3 are considered. Modern approaches to the integration of the accumulated geological and geophysical data into the GSM require the necessary work, primarily such as sedimentological examination of the core and its integration with the results of logging and seismic data. The correct formulation of the problem, its support by the customer at all stages, due to which a close connection between the performed studies and production requests was ensured, were the key to obtaining a high-quality result when solving a seemingly ordinary modeling problem

Abstract Background Whole genome sequencing of cultured pathogens is the state of the art public health response for the bioinformatic source tracking of illness outbreaks. Quasimetagenomics can substantially reduce the amount of culturing needed before a high quality genome can be recovered. Highly accurate short read data is analyzed for single nucleotide polymorphisms and multi-locus sequence types to differentiate strains but cannot span many genomic repeats, resulting in highly fragmented assemblies. Long reads can span repeats, resulting in much more contiguous assemblies, but have lower accuracy than short reads. Results We evaluated the accuracy of Listeria monocytogenes assemblies from enrichments (quasimetagenomes) of naturally-contaminated ice cream using long read (Oxford Nanopore) and short read (Illumina) sequencing data. Accuracy of ten assembly approaches, over a range of sequencing depths, was evaluated by comparing sequence similarity of genes in assemblies to a complete reference genome. Long read assemblies reconstructed a circularized genome as well as a 71 kbp plasmid after 24 h of enrichment; however, high error rates prevented high fidelity gene assembly, even at 150X depth of coverage. Short read assemblies accurately reconstructed the core genes after 28 h of enrichment but produced highly fragmented genomes. Hybrid approaches demonstrated promising results but had biases based upon the initial assembly strategy. Short read assemblies scaffolded with long reads accurately assembled the core genes after just 24 h of enrichment, but were highly fragmented. Long read assemblies polished with short reads reconstructed a circularized genome and plasmid and assembled all the genes after 24 h enrichment but with less fidelity for the core genes than the short read assemblies. Conclusion The integration of long and short read sequencing of quasimetagenomes expedited the reconstruction of a high quality pathogen genome compared to either platform alone. A new and more complete level of information about genome structure, gene order and mobile elements can be added to the public health response by incorporating long read analyses with the standard short read WGS outbreak response.

A new scan-head structure for the scanning tunneling microscope (STM) is proposed, featuring high scan precision and rigidity. The core structure consists of a piezoelectric tube scanner of quadrant type (for XY scans) coaxially housed in a piezoelectric tube with single inner and outer electrodes (for Z scan). They are fixed at one end (called common end). A hollow tantalum shaft is coaxially housed in the XY-scan tube and they are mutually fixed at both ends. When the XY scanner scans, its free end will bring the shaft to scan and the tip which is coaxially inserted in the shaft at the common end will scan a smaller area if the tip protrudes short enough from the common end. The decoupled XY and Z scans are desired for less image distortion and the mechanically reduced scan range has the superiority of reducing the impact of the background electronic noise on the scanner and enhancing the tip positioning precision. High quality atomic resolution images are also shown.

MoldWizard is intended to reduce the time necessary to design complex mold tooling, such as this mold used to manufacture the plastic housings for high-quality nail guns. Depending on the complexity of a mold and its eventual use, the design process can require as many as 50 different steps, including tasks such as importing and cleaning up the CAD model of the part, adjusting its size for shrinkage, separating the core and cavity, generating mold bases, and adding sliders, inserts, and other standard components. Minco Tool & Mold uses Unigraphics to design molds like the one shown in the article for an automobile hubcap. Minco participated in the MoldWizard beta test program. A news group at the website let the test users communicate directly with each other. When beta testers had questions about how to use the program, they posted them in the news group and other testers would respond.

Due to the fact that our society lives in a state of criminality, this study theoretically attempts to show the value of research on the perpetrator's identity and the need to oppose criminality thereof. The purpose of the study is to understand one of the main components of the subject of criminology, which is the perpetrator's identity, to clarify his role and place in the opposing against criminality. The study applied the principle of social naturalism. It is proved that the study of the identity of the perpetrator on the basis of the principle of social naturalism opens up new opportunities in finding, more successful influence on the behavior of persons committing criminal offenses. Because it determines that the core of the perpetrator's identity is an arbitrariness and illusions complex. Liquidation of which will help increase efficiency in the development and implementation of measures to opposing criminality. Under implementing countermeasures, it is important to know on what aspects to focus on to prevent the mechanism of criminal behavior. It is the study of the perpetrator’s identity from the standpoint of socio-naturalistic criminology opens the way for a successful response to the causes and conditions that shape the perpetrator’s identity and contribute thereof to manifestation in the commission of a crime. The socio-naturalistic approach to the study of perpetrator’s identity allows the subjects of counteraction accordingly: develop countermeasures and respond to criminality in general. It is argued that the positive aspect in opposing criminality directly depends on the perpetrator’s identity because through the knowledge of the personal characteristics of those who commit illegal acts, criminogenic factors of crime are explained. These are two interdependent processes. Scientifically substantiated researches of the perpetrator’s identity give the chance to carry out, to correct opposition to criminality. Thus, there is a natural formula: an effective study of the perpetrator’s identity is equal to the effective opposition against criminality. It has been proven that effective research into the perpetrator’s identity is tied to a logical chain of solving extremely complex criminological problems, including the opposing against criminality. And the successful opposition to this socially negative phenomenon shows that there is an adequate influence on criminogenic factors that give rise to criminality, that is, that the developed measures to opposing criminality are effective. The close connection between the perpetrator’s identity and the opposition against criminality is that the perpetrator’s identity is central to the opposition against criminality, due to the fact that effective research on the perpetrator’s identity, it is possible to implement effective measures.

AbstractThis paper deals with the results of the author"s attempts to replicate the obsidian polyhedral cores and prismatic blades of Mesoamerica. Blades have been produced by the direct percussion, indirect percussion, and pressure methods. The pressure method using a chest crutch and a clamp produces cores and blades which are true replicas of aboriginal specimens. The importance of preforming the core and of platform preparation is stressed, and it is pointed out that, usually, actual removal of the blade offers few problems. However, to produce exhausted cores which show the perfection of aboriginal specimens and a large series of nearly identical blades requires good muscular coordination, high quality material, the establishment of patterns or rhythms of motor habits, and the absence of distractions. The author also discusses the difficulties of recovering from mistakes in manufacture.High-speed photography of prismatic blade removal, at 5,000 frames per second, has helped illustrate the behavior of the material and of the stoneworker. These photographs also indicate that under the present experimental and photographic conditions the author (Crabtree) is able to remove a prismatic blade from a core in about 1,250th of a second.

This work developed a well-bonded bcc/fcc bimetal interphase, which was produced by a two-step process involving diffusion bonding and conventional rolling. The high-quality interface maintained its integrity even at fracture. The earlier tensile instability in the core steel layer was constrained by the neighboring stable Cu layers on both sides, leading to extra strain hardening and consequently higher ductility. An increase in twin density or slip bands and shear deformation between the layers might be the primary causes for the observed hardening behaviors in the near-interface regions.

AbstractCOROT is a high precision wide field photometry experiment from space, funded in the framework of the CNES “Petites Missions” program (the PI is A. Baglin). It will observe approximately 30000 objects with mV between 4.5 and 15.5 over long observational periods (up to 150 d), with a time sampling between 1 s and 16 min, a precision of the order of 10−4 per measurement. The scientific objectives are stellar seismology and the search for telluric planets. The instrument and the core program have already been presented in several places. We here focus on a description of the characteristics of the data to be obtained with COROT. The large amount of high quality data collected by COROT will constitute rich material for several research programs beyond the core program as already defined (http://www.astrsp-mrs.fr/www/corot.html). A call for proposal of additional programs will be made during Northern Spring 2000.
