Bloating characteristics of east Texas clays

Bureau Publication GC6501 - to purchase a print copy please go to: https://store.beg.utexas.edu/geologic-circulars/383-gc6501.htmlIncidence of bloating among approximately 600 clay samples from East Texas, ranging in age from Gulfian (Late Cretaceous) to Recent, correlates principally with clay mineralogy-and pH--together an indication of bulk composition--and to a lesser extent with texture, loss on ignition, and content of nonclay refractory minerals. Clay-mineral and pH data permit prediction of bloating with an accuracy of about 80 percent. Montmorillonitic and illitic clays are the best bloaters; bloating occurs in more than 80 percent of clays consisting of less than 30 percent kaolinite, more than l 0 percent illite, and between 20 and 90 percent montmorillonite. Only 10 percent of the high-alumina clays (more than 50 percent kaolinite) bloat; these generally are plastic and carbonaceous. Value of pH is an index of the amount of certain flux and gas-forming materials in clays; accordingly, bloating incidence generally increases with increase in pH. Incidence of bloating also increases slightly with decrease in grain size, increase in plasticity, increase in loss on ignition, and decrease in content of nonclay refractory minerals.Bureau of Economic GeologyUT Librarie

Additive factors and stages of mental processes in task networks.

To perform a task a subject executes mental processes. An experimental manipulation, such as a change in stimulus intensity, is said to selectively influence a process if it changes the duration of that process leaving other process durations unchanged. For random process durations a definition of a factor selectively influencing a process by increments is given in terms of stochastic dominance (also called “the usual stochastic order”. A technique for analyzing reaction times, Sternberg\u27s Additive Factor Method, assumes all the processes are in series. When all processes are in series, each process is called a stage. With the Additive Factor Method, if two experimental factors selectively influence two different stages by increments, the factors will have additive effects on reaction time. An assumption of the Additive Factor Method is that if two experimental factors interact, then they influence the same stage. We consider sets of processes in which some pairs of processes are sequential and some are concurrent (i. e., the processes are partially ordered). We propose a natural definition of a stage for such sets of processes. For partially ordered processes, with our definition of a stage, if two experimental factors selectively influence two different processes by increments, each within a different stage, then the factors have additive effects. If each process selectively influenced by increments is in the same stage, then an interaction is possible, although not inevitable

Fostering Production of Pharmaceutical Products in Developing Countries

The ways in which pharmaceutical products are currently developed, manufactured, and distributed fail to meet the needs of developing countries. The recent emergence of new infectious diseases, the associated surge of healthcare nationalism, and the prevalence of substandard and falsified drugs have strengthened substantially the net benefits of augmenting the capacity of developing countries to produce such products locally. Most previous efforts to do so have foundered. The chance of success in the future would be maximized by the adoption of five strategies : (a) clarifying the zones of discretion created by the relevant treaties to ensure that local firms have the freedom to operate; (b) the use of “production triangles” (collaborations among developing-country governments, local firms, and developed-country pharmaceutical firms) to reduce regulatory impediments and to ensure that there exist adequate markets for locally produced products; (c) developing the human capital base in developing countries through initiatives such as an international apprenticeship system; (d) strengthening the legal and administrative apparatus for preventing the dissemination in developing countries of substandard and falsified drugs; and (e) reliance on regional economic communities to create economies of scale and to ensure that medicines are made available to all residents of all developing countries, while also stimulating competition among local firms. These strategies would both save many lives and strengthen the economic and social development of developing and least-developed countries

An Assessment of the Oil Resource Base of the United States

A select panel of oil resource analysts, convened in August 1992 by the Bureau of Economic Geology, The University of Texas at Austin, and the National Institute for Petroleum and Energy Research (NIPER) at the request of the U.S. Department of Energy, concludes that the remaining, recoverable volume of crude oil in the United States ranges from 99 to 204 billion barrels, inclusive of 25 billion barrels of oil carried as proved reserves by the Energy Information Administration at the end of 1991. The range in estimates reflects different assumptions of price and technology (including the geological ability to apply that technology). The lower estimate assumes a stable oil price of $20 per barrel (1992 dollars) with existing technology. The higher estimate assumes a price of$27 per barrel (1992 dollars) but with advanced technology. The range in estimates of the remaining resource base recoverable under the given assumptions is equivalent to 35 to 75 years of continued U.S. crude oil production at the current annual rate of 2.7 billion barrels.Bureau of Economic Geolog

Age-Related Differences in Vehicle Control and Eye Movement Patterns at Intersections: Older and Middle-Aged Drivers

Older drivers are at increased risk of intersection crashes. Previous work found that older drivers execute less frequent glances for detecting potential threats at intersections than middle-aged drivers. Yet, earlier work has also shown that an active training program doubled the frequency of these glances among older drivers, suggesting that these effects are not necessarily due to age-related functional declines. In light of findings, the current study sought to explore the ability of older drivers to coordinate their head and eye movements while simultaneously steering the vehicle as well as their glance behavior at intersections. In a driving simulator, older (M = 76 yrs) and middle-aged (M = 58 yrs) drivers completed different driving tasks: (1) travelling straight on a highway while scanning for peripheral information (a visual search task) and (2) navigating intersections with areas potential hazard. The results replicate that the older drivers did not execute glances for potential threats to the sides when turning at intersections as frequently as the middle-aged drivers. Furthermore, the results demonstrate costs of performing two concurrent tasks, highway driving and visual search task on the side displays: the older drivers performed more poorly on the visual search task and needed to correct their steering positions more compared to the middle-aged counterparts. The findings are consistent with the predictions and discussed in terms of a decoupling hypothesis, providing an account for the effects of the active training program

Outpatient Commitment: A Competency Based Justification

A recent survey of state statutes for outpatient commitment (Torrey and Kaplan, 1995) indicates that while thirty-five states and the District of Columbia have laws permitting outpatient commitment, Massachusetts is not one of them. Rather, Massachusetts uses a competency-based, substituted-decision-making model for the involuntary administration of medication in the community. To appreciate the Massachusetts model, it is important to understand how this court-ordered involuntary outpatient treatment fits into the overall scheme of outpatient commitment and how it is structured. A review of involuntary outpatient treatment (IOT) literature indicates that it is prudent to distinguish between outpatient commitment, conditional release, and conservatorship-guardianship (Torrey and Kaplan, 1995). Two states whose IOT is based on the guardianship process and is described in the literature are California and New Mexico. Lamb and Weinberger (1992, 1993) have discussed California’s use of guardians for the gravely disabled psychiatric outpatient, and Schneider-Braus (1986) has presented a single case report from New Mexico

Stochastic PERT networks as models of cognition: Derivation of the mean, variance, and distribution of reaction time using Order-of-Processing (OP) diagrams

It is frequently assumed that the mental activity which leads to a given response is made up of separable components or processes. One or more of the processes are assumed to contribute to the time required to respond. Computation of the mean, variance, and distribution of the reaction time is relatively straightforward when all processes are arranged in series or parallel. However, such is not the case when the processes have complex arrangements. A solution to a useful special case of the above problem is proposed. Specifically, it is shown that simple computations yield closed form expressions for the mean, variance, and distribution of reaction time when the processes can be arranged in a stochastic PERT network and when the durations of individual processes are sums of mutually independent, exponentially distributed random variables. The method of solution relies on the construction of an Order-of-Processing (OP) diagram from the original PERT network representation of behavior.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/25195/1/0000634.pd
