Closeness and conflict in children's friendships : relations with friendship stability, adjustment and sociometric status by Richard J Parker( Book )

1 edition published in 2011 in English and held by 2 WorldCat member libraries worldwide

Not many children report relationships with friends that are both close and conflictual. There is a paucity of research examining the trajectory of children's relationship closeness and conflict together over time. This is unfortunate because contentious relationships are related to cardiovascular problems, at least in young adults and because the trajectories of these two aspects of children's relationship quality over time is not understood. Therefore, two longitudinal data sets with younger (mean age 7.5 years at Time 1; four data points over 2 years) and older (mean age 9.9 years at Time 1; two data points over 1 year) children were studied. In both cohorts, measures of friendship quality and peer nominations of liking/disliking as well as overt and relational (older cohort) aggression were completed. Children who reported relationships high in both closeness and conflict were generally satisfied with their friendships; they were not more likely to end their friendships than were children who reported different levels of closeness and conflict (younger cohort). Both boys' and girls' relationship closeness increased over time according to growth curve analyses. The relationships of girls who remained in the same friendship, and who therefore provided ratings on the same friend at each time point, tended to increase in closeness at a different rate over time than the relationships of girls who provided ratings on different friends (younger cohort). Children who reported relationships high in closeness and in conflict were not more aggressive over time than were children who reported different levels of relationship closeness and conflict. However, girls' closeness and overt aggression tracked each other (increased) over time (younger cohort). Girls who reported low social support and negative interactions in their friendships increased the most in overt aggression over time (older cohort). Aggressive and nonaggressive children generally reported similar friendship quality (both cohorts), but the friendship closeness of chronically aggressive boys decreased over time (younger cohort). There were negligible friendship quality differences amongst the sociometric groups. The discussion centers on friendship quality changes in children's continuing friendships, the potential dire effects of turbulent friendships and the friendships of aggressive as well as controversial children

Surface Failure of Titanium Carbide Cermet and Silicon Carbide Balls in Rolling Contact at Temperatures to 2000 degrees F( Book )

2 editions published in 1964 in English and held by 1 WorldCat member library worldwide

The five-ball fatigue tester was used to study the behavior of nickel- bonded titanium carbide cermet and self-bonded silicon carbide balls under repeated stresses applied in rolling contact. Test conditions were 800 and 700 F, a contact angle of 200, and a shaft speed of 950 rpm with a mineral oil lubricant. The nickel-bonded titanium carbide - cermet balls were tested at maximum Hertz stresses from 400,000 to 550,000 psi, while the silicon carbide balls were tested at maximum Hertz stresses from 300,000 to 400,000 Psi. Failure appearance for both materials was unlike the fatigue pits found in bearing steels and a crystallized-glass ceramic. However, the pits were similar to those found in alumina balls (both hot pressed and cold pressed and sintered). A typical failure was a shallow eroded area less than 1 mil deep for the titanium carbide cermet and 3 to 5 mils for the silicon carbide. These failures evolved by progressing slowly from a very small pit to one spanning the running track width. Tests at 800 F with mineral oil lubrication over a range of stresses show that life varies inversely with stress to a power that ranges from 9.7 to 10.5 for the titanium carbide cermet and from 6.9 to 8.6 for the silicon carbide. The load capacity of the titanium carbide and silicon carbide balls was 3 and 1 percent, respectively, that of typical bearing steel balls, and 41 and 18 percent, respectively, that of hot-pressed alumina balls

Rolling-element fatigue life of AISI M-50 and 18-4-1 balls by Richard J Parker( Book )

2 editions published in 1978 in English and held by 1 WorldCat member library worldwide

Rolling-element fatigue studies were conducted with VIM-VAR AISI M-50, EFR 18-4-1, and VAR 18-4-1. Groups of 12.7-mm (1/2-in.) diameter balls of each material were tested in the five-ball fatigue tester. Test conditions included a load of 1540 N (347 lbf) giving a maximum Hertz stress of 5520 MPa (800 000 psi), a shaft speed of 10 700 rpm, and a contact angle of 30 deg. Tests were run at a race temperature of 339 K (150 deg F) with a type II ester (MIL-L-23699) lubricant. The rolling-element fatigue life of VIM-VAR AISI M-50 was not significantly different from that of EFR 18-4-1 or VAR 18-4-1 based on a statistical comparison of the test results

Surface Failure of Alumina Balls Due to Repeated Stresses Applied in Rolling Contact at Temperatures to 2000 degree F( Book )

2 editions published in 1964 in English and held by 1 WorldCat member library worldwide

The five-ball fatigue tester was used to study the behavior of alumina balls under repeated stresses applied in rolling contact. Hot-pressed and cold-pressed-and-sintered 1/2-inch alumina balls were tested at 800 and 7000 F, maximum Hertz stresses of 250,000 to 850,000 psi, a contact angle of 200, and a shaft speed of 950 rpm with a mineral oil lubricant. Failure appearance in alumina was unlike fatigue pits found in bearing steels and a crystallized-glass ceramic. A typical failure was a shallow eroded area approximately 1 mil deep progressing slowly from a very small pit to one spanning the track width. Failure appearance and rate of progression were similar for hot-pressed and cold-pressed-and- sintered alumina. Tests at 800 F with mineral oil lubrication over a range of stresses show that life varies inversely with stress raised to a power that ranges from 9.4 to 10.8 for the hot-pressed alumina and from 6.0 to 8.1 for cold-pressed-and- sintered alumina. The load capacity of hot-pressed alumina at 800 F was one-fifteenth that of a typical bearing steel, seven times that of cold-pressed- and-sintered alumina, and about 15 percent greater than a crystallized-glass ceramic

Effect of component differential hardnesses on residual stress and rolling-contact fatigue by Erwin V Zaretsky( )

1 edition published in 1965 in English and held by 0 WorldCat member libraries worldwide

Residual stress measurements were made in the zone of resolved shearing stress on five SAE 52100 upper test ball specimens with an average Rockwell C hardness of 63.2. These upper test ball specimens were run against lower test balls of nominal Rockwell C hardnesses of 60, 62, 63, 65, and 66 until either ft conditions included an or both components failed because of fatigue. Test conditions included an average race temperature of 150 F, a maximum (Hertz) compressive stress of 800,000 psi, and a highly purified naphthenic mineral oil lubricant. Fatigue lives of the upper test balls were compared with measured residual stresses in the subsurface zone of resolved shearing stress. The compressive residual stress induced in the upper test ball during running is a function of delta H, the hardness of the lower test balls minus the upper test ball hardness An interrelation is indicated among differences in com- ponent hardness, induced compressive residual stress, and fatigue life. Measured values of compressive residual stress within the zone of resolved maximum shearing stress ranged from 178,000 and 294,000 psi. The apparent maximum residual stress occurs above where delta H = 0
