To determine optimal processing conditions for preparation of a SBM that will result in optimal amino acid digestibilities, six lots of high protein SBM were produced under different toasting ...conditions. Specifically, the bed depth in the desolventizer-toaster (DT) was varied (11.4, 12.7, 14.0, 15.2, 17.8, and 20.3
cm). All soybeans were acquired from the same producer, and the preparation and extraction conditions were held constant for all lots. Protein quality indices were measured for each of the resultant SBMs. While the protein dispersability index (PDI) values suggested that all SBMs were adequately processed, the protein solubility in potassium hydroxide (KOH) data suggested that the SBMs produced at bed depths less than or equal to 14.0
cm were adequately processed while those produced at bed depths greater than or equal to 15.2
cm may have been overprocessed. The urease activity results, however, suggest that the SBMs produced at bed depths between 11.4 and 15.2
cm were underprocessed, and those at 17.8 or 20.3
cm were properly cooked. The SBMs then were fed to cecectomized roosters in order to determine true amino acid digestibilities by poultry. True digestibilities of histidine, tryptophan, cysteine, and proline increased (P<0.05) with increasing bed depth. All bed depths resulted in relatively high amino acid digestibilities. Producing SBM at a bed depth between 15.2 and 20.3
cm may result in an increased digestibility of some SBM amino acids by poultry.
We report the first observation of dijet events with a double Pomeron exchange topology produced in p collisions at sqrts = 1800 GeV. The events are characterized by a leading antiproton, two jets in ...the central pseudorapidity region, and a large rapidity gap on the outgoing proton side. We present results on jet kinematics and production rates, compare them with corresponding results from single diffractive and inclusive dijet production, and test factorization.
The circumstances of subtrochanteric fractures following the use of multiple pins for fixation of femoral neck fractures were reviewed in four women (age range, 67-94 years). Internal fixation by use ...of multiple pins in the proximal femur is a common orthopedic procedure. The pins, however, create a significant stress riser in the lateral subtrochanteric cortex. Subtrochanteric fracture has been reported after internal fixation of slipped capital femoral epiphysis with multiple conventional pins and, recently, after internal fixation of femoral neck fractures with large Garden screws.
Stress in the school environment of 269 elementary school children attending Grades 4, 5, and 6 of a metropolitan school district were assessed using the School Stress Questionnaire. The effects of ...sex, ethnic background (minority vs nonminority), type of classroom placement (regular education versus special education), and family structure (traditional versus nontraditional or divorced) were investigated. Children from nontraditional or divorced families had significantly higher school stress than children from intact families. The possibility that these results are a reflection of society's negative attitudes toward children living in nontraditional families is raised.
We present results from a measurement of double diffraction dissociation in pp collisions at the Fermilab Tevatron collider. The production cross section for events with a central pseudorapidity gap ...of width Deltaeta(0)>3 (overlapping eta = 0) is found to be 4.43+/-0.02(stat)+/-1.18(syst) mb 3.42+/-0.01(stat)+/-1.09(syst) mb at square root of (s) = 1800630 GeV. Our results are compared with previous measurements and with predictions based on Regge theory and factorization.
Little is known about the effects of gelling agents in canned dog food on nutrient digestibilities and fecal characteristics. Dogs were fed canned diets with either no gelling agent (control) or one ...of three gelling agents, wheat starch, a guar gum/carrageenan mixture (50:50), and a locust bean meal (LBM)/ carrageenan mixture (50:50) incorporated at two levels (0.2 and 0.5% of the diet on a wet weight basis). Six dogs were fed each diet in a 6 - 7 Youden square design. Dogs fed diets containing gelling agents had higher ileal digestibilities of OM (P = 0.05), fat (P < 0.01), GE (P = 0.02), and total amino acids (P = 0.04) and lower (P < 0.01) total tract DM digestibilities when compared to dogs fed the control diet. Fecal output by dogs fed the control diet, expressed on both an as-is (73.4g/d) and DM (45.6g/d) basis, was lower (P < 0.01) than for dogs fed gelling agent-containing diets (mean 102.3g/d as-is and 57.6g/d DM). Dogs fed the control diet also had lower ( P < 0.01) fecal DM percentages and higher (P = 0.02) fecal scores than dogs fed gelling agent-containing diets.
