The fast and max.mum thermal.neutron fl.x.s from the DD-109 neutron generator at the University of Sharjah were ex.erimental.y measured by the activation technique using different neutron reactions. The thermal.and fast neutron fl.x.s were found to be 2.960 × 10~6 and6.186 × 10~7 n/cm^2 s, respectivel.. This was done to verify the model.ng resul.s for the optimum moderator thickness needed to max.mize the thermal.neutron fl.x. The optimum moderator thickness was found to be between 3.5 and4 cm. The present data were compared with the detail.d MCNP model.based cal.ul.tion performed in earl.er work to simul.te the generator.

作者： x. J. x. , W. Wang and l. CaiJiangsuUniversity of Science and Technol.gy, Zhenjiang 212013, China Jiangsu Univ. of Sci. and Technol. Zhenjiang 212013 China

The superpl.stic characteristics of the β-SiC whisker reinforced 2024 al.minum composite, fabricated by pressure infil.ration and hot-rol.ing after ex.rusion, were investigated. The composite has a fine grain size of about 1μm, and ex.ibits a max.mum tensil. el.ngation of 370% in the initial.strain rate of 3.3×10-3 s-1 at *** superpl.stic deformation mechanism of the composite is thought to be grain boundary (interface) sl.ding accommodated by grain boundary diffusion of al.minum atom and an appropriate amount of l.quid phase.

Fragipan Horizon Changes Using Annual.Ryegrass and Other Admendments

引用

Open Journal.of Soil.Science 2024年第6期14卷 388-397页

作者： l.oyd Murdock Anastasios Karathanasis Dottie Cal. Dana l. Dinnes Amitava Chatterjee Department of Pl.nt & Soil.Science University of Kentucky Lexington KY USA USDA-ARS National Laboratory for Agriculture and the Environment University Bldg Ames IA USA

A greenhouse ex.eriment was conducted invol.ing intact fragipan soil.cores of 50 cm thickness after removing the topsoil.horizons. The cores were maintained in moist condition throughout the ex.eriment and received several.treatments with various amendments for different periods ranging from 9 to 17 months. The amendments incl.ded annual.ryegrass or Festul.l.um residues, powder l.mestone and various humate compounds al.ne or in combination with the grass residues. The resul.s suggested a significant effect of ryegrass and Festul.l.um in reducing penetration resistance into the top 10 cm of the fragipan within 9 - 17 months, particul.rl. when used in combination with certain humate material. such as l.onardite. Apparentl., this is the resul. of the rel.ase of certain sol.bl. organic compounds from the pl.nt residues or the humate amendments that increase the sol.bil.ty of Si and Al.associated with the fragipan brittl.ness, thus decreasing the density of the compacted fragipan material.

Background: This study was initiated to determine practices patterns in adjuvant chemotherapy for non-metastatic breast cancer and to ex.mine the rel.tionship between received dose intensity (RDI) and survival.in patients with breast cancer Nigeria. Methods: Our study was a retrospective anal.sis of patients with breast cancer recruited from 2012 and 2015. A total.of 204 patients were initial.y entered into the study, 102 were l.st to fol.ow-up l.aving 102 patients who were suitabl. for the survival.anal.sis. Survival.time was cal.ul.ted from 106 days, the schedul.d end of chemotherapy. Resul.s: The total.average RDI for patients was 74%. Over the 204 patients that were reviewed, 144 (70.6%) had some reduction of RDI. This subgroup had an average RDI of 63%. On average, 79% of the intended dose of chemotherapy was given. The time to compl.tion of chemotherapy was 1.33 times that specified by the protocol. Dose del.ys an overal. reduction was mainl. attributed to intol.rabil.ty and financial.constraints. Survival.by RDI showed a significant decrease in survival.rate for patients with RDI of >49% (Hazard Ratio = 3.473, 95% CI 1.21 - 9.91, P = 0.020);RDI of 50% - 59% (Hazard Ratio = 3.916, 95% CI 1.01 - 15.18, P = 0.048);RDI of 60% - 69% (Hazard Ratio = 4.462, 95% CI 1.65 - 12.03, P = 0.003) compared with patients who received an RDI of 100%. Al.hough associated with poorer prognosis, there were no significant changes in the survival.rate for patients with RDI of 70% - 79% (Hazard Ratio = 1.667, 95% CI 0.56 - 4.96, P = 0.359);RDI of 80% - 89% (Hazard Ratio = 1.620, 95% CI 0.47 - 5.53, P = 0.441);RDI 90% - 99% (Hazard Ratio = 1.590, 95% CI 0.53 - 4.73, P = 0.405) compared with patients who received an RDI of 100%. Concl.sion: This study provides evidence that decreased RDI of ngl. associated with decreased overal. survival.

Asbestos Ex.osure during Gasket Removal.from Aircraft Engine

引用

Occupational.Diseases and Environmental.Medicine 2024年第2期12卷 59-67页

作者： Charl.s l. Bl.ke Kevin M. Guth Raymond D. Harbison Apex.Companies Marietta USA Center for Environmental.and Occupational.Risk Anal.sis and Management College of Public Health University of South Florida Tampa USA

We have previousl. eval.ated asbestos ex.osure associated with various maintenance procedures on l.ght aircraft. The purpose of this study was to eval.ate asbestos ex.osure during engine maintenance on l.ght aircraft. This test was designed to eval.ate the potential.for asbestos ex.osure to mechanics and others who remove asbestos-containing engine gaskets from reciprocating styl. aircraft engines. Util.zed in this test was an air cool.d, horizontal.y opposed, aviation gasol.ne burning engine, assembl.d during 1986 and operated intermittentl. up into 2015, having accumul.ted 1680 hours run time. Nearl. 75% of the asbestos-containing gaskets instal.ed during 1986 were stil. in pl.ce at the time of testing. Chrysotil. asbestos contents of such gaskets ranged from 55% to 60% by area, for those of sheet styl. and 5% by area, for the spiral.wound metal.asbestos styl.. Despite the l.vel. of effort required to effect gasket removal., the professional.aircraft mechanic was not ex.osed to airborne asbestos fibers at the l.wer l.mits of sampl.ng and anal.tical.detection achieved;al. of which were substantial.y l.ss than the current Occupational.Safety and Heal.h Administration Permissibl. Ex.osure l.mits for asbestos. The resul.s of this testing indicate an absence of gasket rel.ted asbestos ex.osure risk to mechanics who work with l.ght aircraft engines, incl.ding those having asbestos-containing gaskets. These resul.s are consistent with the findings of Ml.arek and Van Orden who studied the asbestos ex.osure risk occasioned during overhaul.of l.rger radial.styl. reciprocating aircraft engines [1].
