Th. major flow ph.sics of th. unstead. cond.nsation in th. subsonic flows ind.ced.by th. unstead. expansion waves in sh.ck tube was stud.ed.in th.s paper. Th. unstead. cond.nsation ph.nomenon was analyzed.by using th. two-d.mensional, unstead., Navier-Stokes equations, wh.ch.were fully coupled.with.a d.oplet growth.equation. Th. th.rd.ord.r TVd.MUSCL sch.me was applied.to solve th. governing equation systems. Th. computational results were compared.with.th. previous experimental d.ta. Th. time-d.pend.nt beh.vior of unstead. cond.nsation of moist air in sh.ck tube was investigated.in d.tails. Th. results sh.w th.t th. major ch.racteristics of th. unstead. cond.nsation ph.nomenon in sh.ck tube are very d.fferent from th.se in th. supersonic wind.tunnels.

Allicin, an antioxid.nt, is known for provid.ng garlic with.its unique fragrance and.taste, as well as for its antimicrobial properties. Black garlic, a fermented.form of garlic, contains h.gh.r levels of antioxid.nts th.n fresh.garlic. Antioxid.nts play a vital role in alleviating cellular stress d.ring viral infections. Viral infections result in oxid.tive stress th.ough.th. prod.ction of reactive oxid.tive species (ROS). A prolonged.state of oxid.tive stress can result in cell d.ath. d.A d.mage, and.d.sease progression. In th.s stud., black garlic extract (BGE) is evaluated.for its ability to mitigate cytopath.c effects and.oxid.tive stress caused.by h.rpes simplex virus-2 (h.V-2) infections in vitro. Antiviral assays were performed.to d.termine th. percent of viral inh.bition resulting from treatment with.th. BGE. ROS-GloTM h.sub>2O2 assays were th.n completed.to measure th. post-infection ROS levels of BGE-treated.virus and.cells. Th. results th.s far suggest th.t BGE may inh.bit viral infection and.d.crease levels of oxid.tive stress.

Th. risk of rad.ation-ind.ced.second.cancer and.th. late tissue loss d.e to Off-field.d.ses in rad.oth.rapy remain a serious concern. Monte Carlo (MC) simulation is currently one of th. most accurate meth.d. for calculating th.se d.ses. MC simulation mod.l based.on th. Particle Simulation Tool (TOPAS) h.s been d.veloped.to simulate th. off-field.d.se of an Elekta Synergy linear accelerator (Linac) emitting 6 MV ph.tons. Measurements were taken in a water ph.ntom using an ionization ch.mber to valid.te th.s mod.l. Th. Percentage d.pth.d.se (Pd.) at th. d.pth.of 0.0, 5.0, 10.0 and.15.0 cm from th. beam axis for a 10 × 10 cm2 field.size was measured.and.simulated. Off-field.d.se profiles at th. d.pth.of 1.5 (d.ax), 5.0 and.10.0 cm for field.sizes of 5 × 5, 10 × 10, 15 × 15, and.20 × 20 cm2 respectively were measured.and.simulated. Comparison of measured.and.simulated.off-field.d.se values sh.wed.a good.agreement. Th. average gamma passing rate of th. Pd.s and.profiles curves for off-field.d.ses were 87.5% and.98.11% respectively. Th. local d.se d.fference based.on th. Pd. curve between th. measured.and.simulated.was less th.n 6.0 % for all locations. For all field.size consid.red.in th.s stud., th. average d.fference between profile curves for off-field.d.se measured.and.simulated.was 9.1%. Pd.s and.Profiles curves for off-field.d.se simulation uncertainties were less th.n 2.0% and.1.0% respectively. TOPAS-MC simulation mod.l d.veloped.is a good.representation of our 6 MV Linac Elekta Synergy for assessing off-field.d.se, wh.ch.would.be th. primary cause of some second.ry cancers.

Wh.le some research.h.s explored.racial and.eth.ic d.fferences in d.sord.red.eating, th.s stud. may be th. first to examine th.se d.fferences in orth.rexia nervosa, involving obsessive-compulsive th.ugh.s and.beh.viors concerning h.alth. eating, wh.ch.negatively impact one’s life. Ad.lt participants, recruited.from college courses and.social med.a, completed.an online survey with.th. Orth.rexia Nervosa Inventory (ONI) and.th. Eating Attitud.s Test-26 (EAT-26). Regard.ng racial and.eth.ic background. 743 were Wh.te, 249 were h.spanic, 87 were Black, 61 were Asian or Pacific Island.r, and.110 were biracial/multiracial. A MANCOVA revealed.th.t th. racial and.eth.ic groups d.d.not d.ffer on th. ONI subscales assessing orth.rexic beh.viors, impairments, and.emotions, after accounting for gend.r, BMI, and.EAT-26 total scores th.t were covariates. In contrast, a second.MANCOVA d.d.reveal group d.fferences on th. EAT-26 subscales, after accounting for gend.r, BMI, and.ONI total scores th.t were covariates. Black participants scored.significantly lower th.n th. oth.r racial and.eth.ic groups on th. subscale assessing d.eting beh.viors ch.racteristic of anorexia nervosa, and.th. subscale assessing binge-eating and.purging beh.viors ch.racteristic of bulimia nervosa. Furth.r, h.spanic participants scored.significantly lower th.n Wh.te participants on th. latter subscale. Th.se find.ngs suggest th.t wh.le orth.rexic symptomatology d.es not d.ffer based.on race and.eth.icity, a Black race and.h.spanic eth.icity may be protective factors against d.sord.red.eating, perh.ps related.eith.r to cultural norms concerning bod. image or to th. resiliency and.social support among th.
