金亭岭金矿与萑香洼金矿矿床地球化学异常模型差异性初探

为了解金亭岭金矿床与萑香洼金矿矿床的烃类组分及微量元素异常展布特征,以期为以后找矿工作提供科学的参考依据,通过对两个矿床的地球化学特征、烃类组分、微量元素对比,建立了矿区的分带模型并做对比。对比得出两个矿床相同点为:在两个矿区的分带模型上可以清晰的发现在轴向上前缘晕均为烃类组分,矿中晕元素均含有Cu、Pb、Zn。这表明两个矿床的形成过程中均有有机质的存在,同时表明烃类组分结合微量元素的找矿方法在两个矿区都具有可行性。不同点:两个矿床微量元素异常的分布位置具有差异性,且烃类组分的最大分带指数也存在差异。这可能和元素自身的活动性及成矿时的物理化学条件、赋矿围岩性质、大地构造背景等差异不同引起的。     

辽西南部成矿规律及找矿

辽西南部的地质找矿工作20世纪50年代应用接触交代成矿理论进行找矿,70年代应用斑岩成矿理论进行找矿,在斑岩找矿工作获得的成果进入低谷期后,经过长期的研究、总结发现：无论是矽卡岩矿床和斑岩矿床都分布于特定的区域、构造位置。综合分析、总结辽西南部成矿规律,认为辽西南部金属矿产的产出为三大成矿带,七处成矿亚带,五个矿床集中区,二个潜在矿床集中区。辽宁有色地质局一0五队应用该成矿规律找到大杨树沟钼矿。继续通过对该成矿规律的研究认为：在大杨沟区及外围和明堂子大庄区也应有矿床产出。

The fibroblast-populated collagen microsphere assay of cell traction force--Part 2: Measurement of the cell traction parameter

In Part 1 of this work, we formulated and analyzed a mathematical model for our fibroblast-populated collagen microsphere (FPCM) assay of cell traction forces (Moon and Tranquillo, 1993). In this assay, the FPCM diameter decreases with time as the cells compact the gel by exerting traction on collagen fibrils. In Part 1 we demonstrated that the diameter reduction profiles for varied initial cell concentration and varied initial FPCM diameter are qualitatively consistent with the model predictions. We show here in Part 2 how predictions of a model similar to that of Part 1, along with the determination of the growth parameters of the cells and the viscoelastic parameters of the gel, allow us to estimate the magnitude of a cell traction parameter, the desired objective index of cell traction forces. The model is based on a monophasic continuum-mechanical theory of cell-extracellular matrix (ECM) mechanical interactions, with a species conservation equation for cells (1), a mass conservation equation for ECM (2), and a mechanical force balance for the cell/ECM composite (3). Using a constant-stress rheometer and a fluids spectrometer in creep and oscillatory shear modes, respectively, we establish and characterize the linear viscoelastic regime for the reconstituted type 1 collagen gel used in our FPCM traction assay and in other assays of cell-collagen mechanical interactions. Creep tests are performed on collagen gel specimens in a state resembling that in our FPCM traction assay (initially uncompacted, and therefore nearly isotropic and at a relatively low collagen concentration of 2.1 mg/ml), yielding measurements of the zero shear viscosity, mu 0 7.4 x 10(6) Poise), and the steady-state creep compliance, J0e. The shear modulus, G (155 dynes/cm2), is then determined from the inverse of J0e in the linear viscoelastic regime. Oscillatory shear tests are performed in strain sweep mode, indicating linear viscoelastic behavior up to shear strains of approximately 10 percent. We discuss the estimation of Poisson's ratio, v, which along with G and mu 0 specifies the assumed isotropic, linear viscoelastic stress tensor for the cell/collagen gel composite which appears in (3). The proliferation rate of fibroblasts in free floating collagen gel (appearing in (1)) is characterized by direct cell counting, yielding an estimate of the first-order growth rate constant, k (5.3 x 10(-6) s-1). These independently measured and estimated parameter values allow us to estimate that the cell traction parameter, tau 0, defined in the active stress tensor which also appears in (3), is in the range of 0.00007-0.0002 dyne.cm4/mg collagen.cell.(ABSTRACT TRUNCATED AT 400 WORDS)     

Electron dose calculation using multiple-scattering theory: a new theory of multiple scattering

Starting from the Boltzmann-Fokker-Planck transport equation, we have developed a new theory of multiple scattering which incorporates the advances already made with our Gaussian multiple-scattering theory for electron dose calculation. This incorporation has been accomplished in a natural way, by modifying the scattering power T and by adding a convolution term to the distribution-function equation of the Gaussian theory. Our previous results concerning increasing the accuracy of the small-angle approximation used and dealing with localized tissue inhomogeneities have thus been maintained, and we have arrived at a complete distribution function in both transverse spatial and angular variables. When integrated over the transverse angular variables, for a first-order small-angle approximation this distribution function for a pencil beam is essentially the same as the Moliere multiple-scattering distribution, which includes large-angle single scattering. For a water phantom, we have used comparisons with EGS4 Monte Carlo calculations to demonstrate the greatly increased accuracy of our new multiple-scattering theory over the Gaussian theory, which includes the usual Fermi-Eyges theory. We have also presented a fairly accurate Gaussian approximation to the pencil-beam dose profiles given by our new theory, which can be used in order to maintain the mathematical simplicity of the predictions of the Fermi-Eyges theory.     

Review of First impressions.

Reviews the book, First impressions, edited by Nalini Ambady and John J. Skowronski (see record 2008-09248-000). This book addresses the questions of how impressions are formed and their effects on thought, feeling, and behaviour. Its goal is to provide a comprehensive overview of the most recent theoretical approaches and empirical data that inform our understanding of perceivers’ immediate impressions of others. Edited by two leading investigators in the field and bringing together an impressive array of experts, the book is well organised and well written, offering a balance of classic and cutting-edge findings. The book is organised into four parts. Part 1 considers biological aspects of impression formation. Part 2 focuses on the factors that make first impressions more or less accurate. Part 3 addresses how facial cues—on their own or in conjunction with other cues—influence the contents or processes of impression formation. Part 4 focuses on how behavioural and environmental cues influence the contents or processes of impression formation. First impressions succeeds in its mandate to provide a broad overview of what we currently know about the processes and moderators involved in impression formation. In so doing, it fulfills an important role, in that no other volume currently exists to organise our knowledge about impression formation—arguably one of the most central topics in social psychology.

Review of Therapeutic communities for addictions: Readings in theory, research and practice.

Reviews the book, Therapeutic communities for addictions: Readings in theory, research and practice edited by George De Leon and James T. Ziegenfus Jr. (1986). The editors represent this collection of articles concerning therapeutic communities (TCs) and substance abuse as "a first." Its stated purpose is to educate "audiences within and outside of the field of addictions" about the relevancy of the TC as a rehabilitative model, to enhance the "credibility and efficacy" of the TC within the range of treatment models and services, and to stimulate dialogue and research among professionals. The first section of this three-part volume addresses the expression of the TC in its two main varieties: the self-help hierarchical model, widely used in the rehabilitation of substance abusers, and the democratic type, more commonly seen in the treatment of psychiatric patients. Part Two concerns the effectiveness of treatment outcomes and processes. Part Three elaborates on some issues previewed in Part Two. A balanced and comprehensive overview of the subject appears to have been accomplished through careful selection of the material. The authors have presented salient issues of theory, practice, research, and development of the TC model within a sociological framework. While this volume has broad appeal for practitioners, researchers, and students, it has special utility for the professional in the addictions field with limited exposure to this treatment modality.

Review of Decision processes.

Reviews the book "Decision processes", edited by R. M. Thrall, C. H. Coombs, and R. L. Davis (see record 1955-00120-000). This volume is a collection of papers from the University of Michigan summer seminar at Santa Monica. California, in 1952. This seminar, devoted to decision processes, had as participants mathematicians, statisticians, psychologists, economists, and philosophers. Most of Part I of this volume is devoted to a discussion of alternative decision criteria. Part II of this volume is concerned with learning theory. Part III is concerned with the utility function. Part IV contains a discussion of certain experimental studies of certain game situations. On the whole, this is a very important volume for decision theorists, but most of them wrote it, or were at least present at the seminar. Its value to working psychologists and economists is less clear. Most of these are working papers, theories about how one might build a theory.

Perceptions of Conflict and Support in Romantic Relationships: The Role of Attachment Anxiety.

Guided by attachment theory, a 2-part study was conducted to test how perceptions of relationship-based conflict and support are associated with relationship satisfaction/closeness and future quality. Dating partners completed diaries for 14 days (Part 1) and then were videotaped while discussing a major problem that occurred during the diary study (Part 2). Part 1 reveals that more anxiously attached individuals perceived more conflict with their dating partners and reported a tendency for conflicts to escalate in severity. Perceptions of daily relationship-based conflicts negatively impacted the perceived satisfaction/closeness and relationship futures of highly anxious individuals, whereas perceptions of greater daily support had positive effects. Part 2 reveals that highly anxious individuals appeared more distressed and escalated the severity of conflicts (rated by observers) and reported feeling more distressed. The authors discuss the unique features of attachment anxiety and how changing perceptions of relationship satisfaction/closeness and stability could erode commitment over time.
