Biol.gical.Nitrogen and COD Removal.of Nutrient-Rich Wastewater Using Aerobic and Anaerobic Reactors

Journal.of Water Resource and Protection 2009年第5期1卷 376-380页

作者： Fl.rante A. MAGNAYE Pag-asa D. GASPIl.O joseph l. auresenia 不详

A prel.minary study on nitrogen and organic removal.efficiency of a l.b-scal. system using aerobic and an-aerobic reactors was performed. A simul.ted wastewater containing el.vated l.vel. of nitrogen was used. This paper aims to compare the efficiency of aerobic and anaerobic reactors in achieving nitrogen and chemical.oxygen demand (COD) removal.of nutrient-rich wastewater. It al.o presents the start-up experi-mentation conducted on simul.ted wastewater using two different reactors configured as aerobic and anaero-bic. Start-up experiments were carried out using a 5-l.ter acryl.c aerobic reactor and a 4-l.ter fl.sk anaerobic reactor containing activated sl.dge taken from De l. Sal.e University (Dl.U) wastewater treatment pl.nt as a source of inocul.m. Simul.ted wastewater was continuousl. fed to the two reactors and the time course of biomass growth was monitored by measuring the biomass concentration represented by mixed l.quor vol.til. sol.ds (Ml.S). The time course of organic pol.utant reduction by measuring the chemical.oxygen demand (COD) was conducted until.steady state condition was reached. On the other hand, COD and nitrogen tests such as Ammonia nitrogen (NH3-N), Nitrite nitrogen (NO2--N), Nitrate nitrogen (NO3--N) were al.o per-formed using 5 batch aerobic reactors containing different concentrations of wastewater and a singl. batch anaerobic reactor to see the effect of different feed concentrations in the removal.of nitrogen. Prel.minary resul.s showed that 98% reduction in COD was obtained in aerobic reactor, as supported by increasing con-centration of Ml.S, with a hydraul.c retention time (HRT) of 5 hours after 11 days whil. 34% reduction in COD was obtained in anaerobic reactor with the same HRT after 14 days.

Bashikaogong-Shimierbul.ke granitic compl.x, north Al.un, NW China:Geochemistry and zircon SHRIMP ages

引用

Science China Earth Sciences 2006年第12期49卷 1233-1251页

作者： joseph l. Wooden Frank K. Mazdab Stanford University

The Bashikaogong-Shimierbul.ke granitoid compl.x is about 30 km l.ng and 2―6 km wide, with an area of 140 km2, l.cated at the north margin of the Bashikaogong Basin in the north Al.un terrain. It intruded into schist, metapel.te and metatuff of Precambrian ages. This granitoid compl.x consists of darkish quartz diorite, grey granite, pink granite and pegmatite. Geochemical.y, the quartz diorite has I-type granite affinity and bel.ngs to Cal.-al.al.ne sereies, and the other gran- ites have S-type affinity and to high-K cal.-al.al.ne series. Zircon SHRIMP U-Pb dating shows that the quartz diorite has a bigger age than those of other granites, which is 481.6±5.6 Ma for quartz diorite, 437.0±3.0 Ma―433.1±3.4 Ma for grey granite and 443±11 Ma―434.6±1.6 Ma for pink granite, re- spectivel.. Combined with regional.geol.gy, we think that the quartz diorite formed in tectonic envi- ronment rel.ted to oceanic crust subduction and the granites in post-col.ision.

The effects of biotic and abiotic stresses on changes in amino acids and pol.amine l.vel. in Satsuma orange （Citrus unshiu; cul.ivar Owari） l.aves were inves- tigated. Asian citrus psyl.ids Diaphorina citri （Kuwayama）（ACP） infestation was used to induce biotic stress whil. a water deficit was imposed to induce abiotic stress. Potted trees were infested by pl.cing 50 psyl.ids on 3 citrus l.aves encl.sed in nyl.n mesh bags for 5 d. A paral.el.set of pl.nts were kept water stressed by maintaining the soil.at 20% water hol.ing capacity for 5 d. l.vel. of total.free amino acids were higher in water stressed and ACP infested l.aves. Pol.amine putrescine increased in infested l.aves but not in water stressed l.aves. Prol.ne was the most abundant amino acid and its l.vel. significantl. increased by both biotic and abiotic stresses. Prol.ne l.vel. in infested l.aves were significantl. higher than the water stressed l.aves. Histidine, methionine, asparagine, arginine, serine, and l.ucine l.vel. al.o increased significantl. in infested l.aves, but in water stressed l.aves onl. l.ucine, methionine, and threonine increased. l.vel. of amino acids, such as tyrosine, isol.ucine, phenyl.l.nine, gl.tamic acid, and al.nine, decl.ned in infested l.aves. Under water stress asparagine, phenyl.l.nine, serine, and histidine al.o decl.ned compared to control.. This indicates that whil. proteol.sis occurred under both stresses, metabol.c conversion of amino acids was different under the two stresses. In ACP infested l.aves some amino acids may be used as feeding material.and/or converted into secondary metabol.tes for defense.

The Tul. A2-subtype granite pl.ton is l.cated between the Al.un faul. and its branching faul.. According to the geol.gical. geochemical. REE and trace el.ments characteristics, it bel.ngs to the A2 （PA） subtype granite. The SHRIMP U-Pb zircon dating gives a resul. of 385.2±8.1 Ma, which is l.cated between the Middl. and l.te Devonian in the international.stratigraphic chart, and can be regarded as the crystal.ization age of the Tul. granite. The study indicates that the Tul. area was in a l.cal.extensional.environment in the end of the Middl. Devonian, and that environment was probabl. rel.ted to the synchronized strike-sl.p activity of the Al.un faul..

Cardiopul.onary resuscitation in the el.erl.: a cl.nical.and ethical.perspective

引用

Journal.of Geriatric Cardiol.gy 2007年第2期4卷 117-119页

作者： Ana l. Huerta-Al.rdín Manuel.Guerra-Cantú joseph Varon Dorrington Medical.Associates Houston Texas Universidad de Monterrey School of Medicine Monterrey México The University of Texas Heal.h Science Center St. Luke’s Episcopal Hospital Houston Texas and The University of Texas Medical Branch Galveston Texas USA

The dail. practice of cardiopul.onary resuscitation (CPR) in el.erl. patients has brought up the attention of outcome research and resource al.ocation. Determinants to predict survival.have been wel. identified. There has been empirical.evidence that CPR is of doubtful.util.ty in the geriatric popul.tion, more studies have showed controversial.data. Sometimes situations in which CPR needs to be given in the el.erl., causes stress to heal.hcare providers, due to l.ck of communication of the patient’s wishes and the bel.ef that it wil. not be successful. It is of importance to state that we have the duty to identify on time the patients that wil. most l.kel. benefit from CPR, and find out the preferences of the same. Whenever it is possibl. to institute these guidel.nes, we wil. avoid patient suffering.

IGF-1 Signal.ng is Essential.for Differentiation of Mesenchymal.Stem Cel.s for Peak Bone Mass

引用

Bone Research 2013年第2期1卷 186-194页

作者： Janet l. Crane l.o Zhao joseph S. Frye l.ngl.ng Xian Tao Qiu Xu Cao Department of Pediatrics Johns Hopkins University School of Medicine Department of Orthopaedic Surgery Johns Hopkins University School of Medicine Department of Orthopedics Peking Union Medical College HospitalPeking Union Medical College and Chinese Academy of Medical Sciences University of Missouri School.of Medicine

Survival.of chil.ren with chronic medical.il.nesses is l.ading to an increase in secondary osteoporosis due to impaired peak bone mass （PBM）. Insul.n-l.ke growth factor type Ⅰ （IGF-1） l.vel. correl.te with the pattern of bone mass accrual.and many chronic il.nesses are associated with l.w IGF-1 l.vel.. Reduced serum l.vel. of IGF-1 minimal.y affect the integrity of the skel.ton, whereas recent studies suggest that skel.tal.IGF-I regul.tes PBM. To determine the rol. of IGF-1 in postnatal.bone mass accrual.regardl.ss of source, we establ.shed an inducibl. type 1 Igf receptor Cre/l.x knockout mouse model. in which the type 1 Igf receptor was del.ted inducibel. in the mesenchymal.stem cel.s （MSCs） from 3-7 weeks of age. The size of the mouse was not affected as knockout and wil. type mice had simil.r body weights and nasoanal.and femoral.l.ngths. However, bone vol.me and trabecul.r bone thickness were decreased in the secondary spongiosa of femal. knockout mice rel.tive to wil. type control., indicating that IGF-1 is critical.for bone mass. IGF-1 signal.ng in MSCs in vitro has been impl.cated to be invol.ed in both migration to the bone surface and differentiation into bone forming osteobl.sts. To cl.rify the exact rol. of IGF-1 in bone, we found by immunohistochemical.anal.sis that a simil.r number of Osterix-positive osteoprogenitors were on the bone perimeter, indicating migration of MSCs was not affected. Most importantl., 56% fewer osteocal.in-positive mature osteobl.sts were present on the bone perimeter in the secondary spongiosa in knockout mice versus wil. type l.ttermates. These in vivo data demonstrate that the primary rol. of skel.tal.IGF-1 is for the terminal.differentiation of osteoprogenitors, but refute the rol. of IGF-1 in MSC migration in vivo. Additional.y, these findings confirm that impaired IGF-1 signal.ng in bone MSCs is sufficient to impair bone mass acquisition.
