Objective: To explore whether reasons for enrollment in a pediatric multidisciplinary weight management program (PMWMP) are associated with subsequent weight loss. Method: A retrospective analysis of obese adolescents (12-18 years old, body mass index [BMI] > 95th percentile) who enrolled in a PMWMP from April 2007 to March 2009, and had BMI measurements at weeks 1 and 12. Reasons for enrollment were obtained from parents’ responses to an enrollment questionnaire (which allowed selection of more than one reason). The most common reasons for enrollment were computed. Linear regression was used to explore associations between mean change in BMI and reasons for enrollment, controlling for demographic and anthropometric factors. Results: Most of the 90 adolescents who met the inclusion criteria were female (70%) and white (57%). Mean age was 14.5 years and mean initial BMI was 42 kg/m2. The most common reasons for enrolling in the PMWMP were due to concerns about adolescents’ physical health (96%), concerns about adolescents’ mental health (76%), and because of a physician recommendation (73%). The mean 12-week change in BMI showed a greater decrease for those who enrolled due to a physicians’ recommendation versus those who did not (−1.5 vs −0.5 kg/m2: P < .05). This finding remained significant even when controlling for the covariates of interest. Conclusions: A physician’s recommendation to join a PMWMP appears to be associated with greater weight loss among obese adolescents than other reasons for enrollment. Further research should explore how physician involvement affects long-term weight loss.

Abstract Tread wear rates during first wear measured by groove depth and weight changes do not always agree. Sometimes, the groove depth method shows a high rate and the weight loss method a low rate. Reported here are experiments designed to determine if grooves show depth changes without wear. Four tires were measured before mounting on a wheel, after mounting and inflation, and after inflation and storage. The mounted and inflated tires showed shallower shoulder grooves and deeper center grooves than the unmounted tires. In a second experiment, tires were measured immediately after a tread wear test and then stored mounted for two weeks before remeasuring. Each groove became deeper, and there was no change in the crown radius of any tire.

The inhibition efficiency (IE) of sodium molybdate (SM) in controlling corrosion of carbon steel in an aqueous solution containing 120 ppm of Cl-, in the absence and presence of Zn2+has been evaluated by weight-loss method. A synergistic effect exists between SM and Zn2+when the concentration of Zn2+is 25 ppm and above. Inhibition efficiencies obtained are greater than 85%. Antagonistic effect exists between SM and Zn2+when the concentration of Zn2+is 10 ppm and below. The SM-Zn2+system shows excellent IE up to third day. Above third day IE decreases. Acceleration of corrosion takes place. Excellent IE is shown at pH 5,7 and 12. At pH 9, IE decreases since Zn2+is precipitated as Zn(OH)2in the bulk of the solution. Polarization study reveals that SM-Zn2+system functions as a mixed inhibitor. FTIR spectra reveal that the protective film consists of Fe2+-SM complex and Zn(OH)2.

Erosion is a main failure of tubings and downhole tools in Changqing gas field. It is necessary to evaluate the erosion rate for the safety of tubing and strings. In this paper, the erosion of P110 steel, in the 0.2%wt guar gum fracturing fluid which contains sands, is investigated by weight loss method in the self-made jet experiment device. It is indicated that the erosion rate increases with the increment of slurry velocity exponentially. When the slurry velocity is in low velocity area, the electrochemical corrosion of dissolved oxygen dominates in erosion mechanism; when slurry velocity increases into middle velocity area, the weight loss is controlled by the synergism of corrosion-erosion; and when the slurry velocity increases into high velocity area, the weight loss rate is dominantly depended on erosion of particles. The results can provide guidelines for large-scale fracturing work of Changqing gas fields.

The aim of this study is to determine the corrosion effect of palm oil methyl ester (POME) on aluminium alloy 5083 (AA5083). The static immersion test was carried out at 60°C for 68 days according to ASTM G–31–72. The corrosion analysis was done by using weight loss method and electrochemical test. The result from weight loss method shows the decreasing in weight loss of AA5083 which signifies the ability of POME to reduce corrosion rate. The electrochemical test shows the decreasing in polarization resistance,Rp, while the corrosion current densities, Icorr, increase. The corrosion rate reduces from 2.250mpy to 0.1946mpy. The low concentration of fatty acid C18:2 and high anti oxidant element contributes to the reduction of corrosion rate of AA5083 in POME.

Introduction/Objectives: Weight gain concerns remain a barrier to tobacco cessation. Literature suggests that weight gain can occur after stopping tobacco, but continuing tobacco can have far worse outcomes. Limited information is available regarding weight gain in military personnel. The objective of this study was to evaluate weight change in veterans that stopped tobacco for a minimum of 12 months enrolled in a pharmacist managed telephone tobacco cessation clinic (PMTTCC). Methods: A retrospective analysis of veterans who had been tobacco-free for 12 months enrolled in a PMTTCC were included in this analysis. Primary outcomes were change in weight (kg) and body mass index (BMI) from baseline. Descriptive data were utilized where appropriate and paired t-tests were utilized for the primary outcomes. Results: Seventy-seven patients were screened and 10 were excluded. Sixty-seven veterans met inclusion criteria and were mostly male (91%, n = 61) and Caucasian (74.6%, n = 50). At 12 months post cessation, the mean weight gain was (1.81 kg ± 6.83, P = .03) and BMI (0.51 ± 2.23 kg/m2, P = .06). Conclusions: Veterans appeared to have minimal weight gain despite statistical significance and no statistical change with BMI after 12 months of being tobacco-free. Results suggest that the long-term weight gain is minimal, and a comprehensive tobacco cessation program can be helpful to improve weight outcomes.
