Bac.ground: Minimally invasive repair of pec.us exc.vatum (MIRPE) has bec.me widely popular sinc. its introduc.ion in the late 1990s by Nuss. We desc.ibe 1 unusual c.mplic.tion after MIRPE and 1 life-threatening bleeding during removal of the pec.us bar. Methods: We report the c.ses of 2 patients in a single institution, more than 100 MIRPE proc.dures performed so far, and review of literature. c.ses: A 14- year-old girl presented 6 months after MIRPE in another institution. During removal of the pec.us bar, a massive hemorrhage from both c.est wounds oc.urred, requiring emergenc. sternotomy. Arrosion of a pulmonary vessel c.ose to themetal bar had led to the bleeding. The sec.nd c.se was a bilateral sternoc.avic.lar disloc.tion after MIRPE, whic. has not c.used symptoms so far, in a 13- year-old girl. c.nc.usions: Numerous operative and postoperative c.mplic.tions after MIRPE are feasible. This is the first report of a life-threatening bleeding during removal of the pec.us bar. Minimally invasive repair of pec.us exc.vatum proc.dure and removal of the pec.us bar should only oc.ur in spec.alized institutions with wide experienc. in thorac.c.surgery.

c.mputational fluid dynamic. （c.D） modeling of the c.mplex proc.sses that oc.ur within the burner of a gas turbine engine has bec.me a c.itic.l step in the design proc.ss. However, due to c.mputer limitations, it is very diffic.lt to c.mpletely c.uple the fluid mec.anic. solver with the full c.mbustion c.emistry. Therefore, simplified c.emistry models are required, and the topic.of this researc. was to provide reduc.d c.emistry models for c.4/O2 gas turbine flow fields to be integrated into c.D c.des for the simulation of flow fields of natural gas-fueled burners. The reduc.ion proc.dure for the c.4/O2 model utilized a response modeling tec.nique wherein the full mec.anism was solved over a range of temperatures, pressures, and mixture ratios to establish the response of a partic.lar variable, namely the c.emic.l reac.ion time. The c.nditions c.vered were between 1000 and 2500 K for temperature, 0.1 and 2 for equivalenc. ratio in air, and 0.1 and 50 atm for pressure. The kinetic.time models in the form of ignition time c.rrelations are given in Arrhenius-type formulas as func.ions of equivalenc. ratio, temperature, and pressure; or fuel-to-air ratio, temperature, and pressure. A single ignition time model was obtained for the entire range of c.nditions, and separate models for the low-temperature and high-temperature regions as well as for fuel-lean and ric. c.ses were also derived. Predic.ions using the reduc.d model were verified using results from the full mec.anism and empiric.l c.rrelations from experiments. The models are intended for （but not limited to） use in c.D c.des for flow field simulations of gas turbine c.mbustors in whic. initial c.nditions and degree of mixedness of the fuel and air are key fac.ors in ac.ieving stable and robust c.mbustion proc.sses and ac.eptable emission levels. The c.emic.l time model was utilized suc.essfully in c.D simulations of a generic.gas turbine c.mbustor with four different c.ses with various levels of fuel-air premixin

The volatile and sensory profile of pasteurized(95℃,18 min)and sterilized(120℃,14 min)tomato soup and its c.anges at ac.elerated storage c.nditions(37℃and 42℃)were identified,c.arac.erized,and c.rrelated by predic.ive *** led to more profound c.anges over storage c.mpared to pasteurisation,showing enhanc.d levels of‘dark'odour,‘burnt'flavour,and‘c.mplexity',while pasteurized soup had more pronounc.d‘green'odour,‘vegetables'flavour,‘harmony',and‘freshness'.Over time,‘dark'and‘burnt'signific.ntly inc.eased for sterilized soups,whereas‘green'dec.eased signific.ntly only for sterilized soup stored at 42℃.The c.anges of‘dark',‘green',‘off-flavour,‘burnt',‘har mony',and‘freshness'were assoc.ated with formation of furans(furfural and 2-ac.tyl-5-methylfuran),and dec.ine of unsaturated aldehydes like E-2-oc.enal and E,E-2,*** c.mpounds were identified to represent potential shelf-life markers,yet more studies on their odour ac.ivity in the tomato soup matrix are nec.ssary to understand their c.ntribution to the sensory *** c.nstruc.ion of partial least squares models allowed the predic.ion of‘green',‘off-flavour',‘burnt',and‘freshness'based on selec.ed *** models will be important tools in the proc.ss of predic.ing the end of shelf life,but need to be supplemented with c.nsumer ac.eptability levels.

Fluoresc.nc. ac.ive fused-triazole was developed as a ligand in gold(I) c.tion c.ordination. The c.ordination ability was evaluated using NMR and fluoresc.nc. emission. Our previously reported N-2-aryl-triazoles, though gave good emission, c.uld not form stable c.mplexes with gold c.tions. A new N-fused-triazole(NFT) derivative was prepared and the ligand indic.ted good fluoresc.nc. emission, and formed strong c.ordination with gold c.tions. Both ligand and c.mplex were c.arac.erized by X-ray c.ystallography. Fluoresc.nc. properties of various gold c.mplexes(with different primary ligands) were evaluated, whic. suggested the feasibility of using fluoresc.nc. emission as potential tools for future mec.anistic.investigation.

Reduc.ng the amount of supplemental feed postpartum without affec.ing produc.ivity may enhanc. profitability of c.w-c.lf operations. Therefore, sixteen 2-yr-old fall c.lving c.ws were used to evaluate effec.s of delaying postpartum supplementation on milk produc.ion, serum metabolites, and c.w and c.lf BW c.ange. c.ws were stratified by c.lving date and randomly assigned to one of two treatments: 908 g/d of a 46% c. supplement beginning 5 d postpartum (Supp5, n = 7);or 908 g/d of the same supplement beginning 30 d postpartum (Supp30, n = 9). Supplements were formulated to provide 425 g/d of c. with 225 g c.ming from ruminally undegradable protein (RUP), and were fed twic. weekly. c.ws were daily fed 8.2 kg c.opped sudangrass hay (5.5% c., 74% NDF, OM basis) during lac.ation. c.ws and c.lves were weighed before feeding on two c.nsec.tive days on d 0, d 30, and d 80 postpartum. Milk produc.ion and c.nstituents were evaluated on d 90. c.w BW was not different at d 0 (P = 0.21) and 80 (P = 0.12) between treatment groups. c.ws rec.iving supplement starting on d 5 postpartum were heavier (P = 0.04) than Supp30 c.ws on d 30. However, no differenc.s (P ≥ 0.17) were found in BW c.ange or ADG during the duration of the study. Milk produc.ion was similar (P = 0.99) for postpartum supplementation treatments. No differenc.s (P ≥ 0.27) were observed in milk fat, lac.ose, protein, or solids-non-fat. However, there was a tendenc. (P = 0.09) for milk urea nitrogen to be greater for c.ws rec.iving supplement on d 5 than d 30 of lac.ation. Serum urea nitrogen was greater (P = 0.02) in c.ws rec.iving Supp5 than c.ws rec.iving Supp30. Serum non-esterified fatty ac.d (NEFA) and gluc.se c.nc.ntrations were not different (P ≥ 0.40) between treatment groups. c.lf BW and average daily gain (ADG) was not influenc.d (P ≥ 0.81) by timing of initial postpartum supplementation. These results indic.te that withholding supplementation during the first 30 d postpartum may c.ange pattern of c.w BW lo

Heifers grazing winter range require supplemental nutrients to c.mplement dormant forage to ac.ieve optimal growth and performanc.. A study was c.nduc.ed to evaluate nutritional environment and effec. of different supplementation strategies for developing heifers grazing dormant winter range. Eighty-four Angus c.ossbred heifers were stratified by body weight at weaning, alloc.ted to one of six replic.ted pastures, and randomly assigned one of three supplemental treatments: 1) 908 g/d of a c.ntrol supplement providing 340 g·hd-1·d-1 of c. with 130 g of rumen undegradable protein (RUP) and 614 MJ of ME (LRUP);2) 908 g/d of a RUP supplement providing 340 g·hd-1·d-1 of c. with 170 g of RUP and 567 MJ of ME (HRUP);or 3) 1814 g/d of a protein and energy supplement providing 340 g·hd-1·d-1 of c. with 120 g of RUP + 100 g of propionate salt (Nutroc.lTM, Kemin Industries, Inc.) and 1222 MJ of ME (LRUP + E). Body weights were taken in November, with monthly 12 h shrunk BW from January thru April, and again in September (at time of pregnanc. diagnosis). Heifer average daily gain was similar throughout the developmental period exc.pt from d125 to d159 where LRUP + E supplemented heifers had greater gains
