Resolution Imaging

Single molecule resolution in electron beam sensitive, uncoated, noncrystalline materials has been impossible except in thin Pt-C replicas ≤ 150Å) which are resistant to the electron beam destruction. Previously the granularity of metal film replicas limited their resolution to ≥ 20Å. This paper demonstrates that Pt-C film granularity and resolution are a function of the method of replication and other controllable factors. Low angle 20° rotary , 45° unidirectional and vertical 9.7±1 Å Pt-C films deposited on mica under the same conditions were compared in Fig. 1. Vertical replication had a 5A granularity (Fig. 1c), the highest resolution (table), and coated the whole surface. 45° replication had a 9Å granulartiy (Fig. 1b), a slightly poorer resolution (table) and did not coat the whole surface. 20° rotary replication was unsuitable for high resolution imaging with 20-25Å granularity (Fig. 1a) and resolution 2-3 times poorer (table). Resolution is defined here as the greatest distance for which the metal coat on two opposing faces just grow together, that is, two times the apparent film thickness on a single vertical surface.

Controllable Factors

A sense of personal control is an important resource that helps people maintain emotional stability and successfully negotiate their way through life. People foster their perceived control by focusing on reachable goals, creating new avenues for control, and accepting difficult-to-change circumstances. In general, perceived control need not be realistic in order to have beneficial effects, although in the area of health promotion, overestimating one's control can reduce the motivation to engage in protection. Research on ethnic differences in the benefits of a sense of personal control suggests that those from more collectivistic cultures or subcultures may be less benefited by a sense of personal control, relying instead on a socially derived sense of control. Successful interventions to enhance personal control include programs that bolster coping skills, give options and decisions to participants, and provide training that encourages attributions to controllable factors. Future research should further explore ethnic differences in the effects of personal control, the consequences of unrealistic control perceptions, and interventions to enhance the sense of control.

Single Jersey

This research investigates the effect of fiber, yarn and fabric variables on the bagging behavior of single jersey weft knitted fabrics interpreted in terms of bagging fatigue percentage. In order to estimate the optimum process conditions and to examine the individual effects of each controllable factor on a particular response, Taguchi's experimental design was used. The controllable factors considered in this research are blending ratio, yarn twist and count, fabric structure and fabric density. The findings show that fabric structure has the largest effect on the fabric bagging. Factor yarn twist is second and is followed by fabric density, blend ratio and yarn count. The optimum conditions to achieve the least bagging fatigue ratio were determined.

Robust Parameter

One of the key issues in robust parameter design is to configure the controllable factors to minimize the variance due to noise variables. However, it can sometimes happen that the number of control variables is greater than the number of noise variables. When this occurs, two important situations arise. One is that the variance due to noise variables can be brought down to zero The second is that multiple optimal control variable settings become available to the experimenter. A simultaneous confidence region for such a locus of points not only provides a region of uncertainty about such a solution, but also provides a statistical test of whether or not such points lie within the region of experimentation or a feasible region of operation. However, this situation requires a confidence region for the multiple-solution factor levels that provides proper simultaneous coverage. This requirement has not been previously recognized in the literature. In the case where the number of control variables is greater than the number of noise variables, we show how to construct critical values needed to maintain the simultaneous coverage rate. Two examples are provided as a demonstration of the practical need to adjust the critical values for simultaneous coverage.

This study study aimed to examine (a) adolescents’ attributions and emotions for their subjectively perceived good and bad relationships with their parents, (b) the association of the intuitive and attributional appraisals of the adolescent-parent relationship with the subsequent emotions, and (c) the role of the perceived importance of the good adolescent-parent relationship in the generation of attributions and emotions, and in the impact of attributions on emotions. The sample comprised 670 adolescents, both genders, aged 14-17 years old, representing various parental socioeconomic levels. The results showed that: (a) It was extremely important for the adolescents to have good relationships with their parents, (b) the perceived good adolescent-parent relationships were attributed to internal, stable and personal controllable factors, along with parent- and self-parent interactive- related factors, while the estimated as bad relationships were attributed to external, stable, personal uncontrollable and external controllable factors (parents’ negative properties), (c) the adolescents experienced intense positive and negative emotions (mainly, general / outcome- dependent) for the perceived good and bad relationships with their parents, respectively, (d) both intuitive and attributional appraisals of the relationship were associated with the emotions, particularly in the perceived bad adolescent-parent relationship, and (e) the relative strength of the association of the attributional dimensions with the emotions varied between the perceived good and bad adolescent-parent relationship and across the various emotions. Keywords: Adolescent-Parent Relationship, Attributions, Emotions, Intuitive Appraisal.

Paste Backfill

This paper presents in-stope measurements of total stress and pore-water pressure at strategic locations within three underground stopes at the Raleigh mine site (Western Australia) that were filled with cemented paste backfill (CPB). The three stopes were very similar in shape. Key differences among the stopes were the filling and resting schedules, the barricade drainage systems used, and the cement content of the CPB. Data from the stopes are compared to determine which controllable factors most significantly influence barricade pressures during and after filling. The most significant factor was the scheduling of rest periods between filling, with even very short pauses in filling dramatically reducing the rate of increase of pore-water pressure and total stress with increasing height of fill.

A qualitative design was used to explore the experience of positive adjustment following a heart attack. Ten men attending a cardiac rehabilitation programme completed in-depth semi-structured interviews. An overarching theme: ‘I was in control of it from the start’ emerged with six subthemes, relating to intrapersonal and interpersonal factors and processes. The subthemes reflected the importance of identifying controllable versus non-controllable factors and employing adaptive coping strategies.

Hydraulic fracturing with oriented perforations is an effective technology for reservoir stimulation for gas development in shale reservoirs. However, fracture reorientation during fracturing operation can affect the fracture conductivity and hinder the effective production of shale gas. In the present work, a numerical simulation model for investigating fracture reorientation during fracturing with oriented perforations was established, and it was verified to be suitable for all investigations in this paper. Based on this, factors (such as injection rate and fluid viscosity) affecting both of initiation and reorientation of the hydraulically induced fractures were investigated. The investigation results show that the fluid viscosity has little effect on initiation pressure of hydraulically induced fracture during fracturing operation, and the initiation pressure is mainly affected by perforation azimuth, injection rate and the stress difference. Moreover, the investigation results also show that perforation azimuth and difference between two horizontal principle stresses are the two most important factors affecting fracture reorientation. Based on the investigation results, the optimization of fracturing design can be achieved by adjusting some controllable factors. However, the regret is that the research object herein is a single fracture, and the interaction between fractures during fracturing operation needs to be further explored.

Physical And Chemical

The physical and chemical properties of materials are determined in part by microstructure. Grain orientation and size in polycrystalline aggregates affect, for example, yield strength, catalytic efficiency, chemisorption, physisorption, fracture and a host of other properties. The final grain morphology is often determined by thermal processing, addition of a second phase, deformation, etc. However, in order to effectively tailor the microstructure for specific applications, the mechanism and kinetics of grain growth must be known. Unfortunately, present theories predict grain growth kinetics (1–3) which often differ from experimental observation, have little predictive ability with respect to microstructure and are not easily generalized to account for experimentally controllable factors.
