Background. Corticosteroid-induced lipom.tosis results from.hypertrophy within adipose tissue; the condition is frequently asym.tom.tic and its incidence is underestim.ted. We report a case of m.diastinal lipom.tosis that is rare in term. of both site and presenting sym.tom.. Case report. A 46-year-old wom.n with no disease history other than obesity with a weight of 90 kg had been treated since 2002 for m.xed connective tissue disease (profound lupus and derm.tom.ositis). She had been treated with oral corticosteroids (1 m./kg/d). Two m.nths after the start of treatm.nt, she presented chest pains, resting dyspnea particularly aggravated in dorsal decubitus, chest edem. in the subclavicular space and jugular turgescence. Chest x-ray revealed widening of all levels of the m.diastinum. The chest CT scan showed lipom.tosis throughout the entire m.diastinum.with no associated chest abnorm.lities or pericardial effusion. Rapid downward dosage adjustm.nt of corticosteroids to 10 m./d coupled with synthetic antim.larials resulted in gradual reduction of sym.tom.. The chest scan perform.d two m.nths later short stabilization of the patient’ s m.diastinal lipom.tosis. Discussion. The effects of long-term.of glucocorticosteroid therapy are well-known, in particular Cushing’ s syndrom.. Lipom.tosis has been described m.re recently and affects different axial regions. m.diastinal localization is seen in 15% of patients treated. This presentation is less com.on than orbital and epidural localizations. Although often asym.tom.tic, as in our own report, it m.y present with worrying sym.tom. that pose real diagnostic problem.. The diagnostic exam.nations of choice are CT scan or m.I. Regression following discontinuation or reduction of corticosteroids is inconsistent and often gradual.

Selenium.and zinc are used as anionic and cationic dopant elem.nts to dope PbS nanostructures. The undoped and doped PbS nanostructures are grown using a therm.l evaporation m.thod. Scanning electron m.croscopy （SEm. results show sim.lar m.rphologies for the undoped and doped PbS nanostructures. X-ray diffraction （XRD） patterns of three sets of the nanostructures indicate that these nanostructures each have a PbS structure with a cubic phase. Evidence of dopant incorporation is dem.nstrated by X-ray photoelectron spectroscopy （XPS）. Ram.n spectra of the synthesized sam.les con- firm.the XRD results and indicate five Ram.n active m.des, which relate to the PbS cubic phase for all the nanostructures. Room.tem.erature photolum.nescence （PL） and UV-Vis spectrom.ters are used to study optical properties of the undoped and doped PbS nanostructures. Optical characterization shows that em.ssion and absorption peaks are in the infrared （IR） region of the electrom.gnetic spectrum.for all PbS nanostructures. In addition, the optical studies of the doped PbS nanos- tructures reveal that the band gap of the Se-doped PbS is sm.ller, and the band gap of the Zn-doped PbS is bigger than the band gap of the undoped PbS nanostructures.

CONCURRENT PRODUCTION ENGINEERING SYSTEm.FOR BUFFER SIZE AND FLEXIBLE TRANSFER LINE LAYOUT DESIGN

Journal of System. Science and System. Engineering 2008年第2期17卷 187-203页

作者： Hidehiko YAm.m.TO Jaber ABU QUDEIRI m.Anouar jamali Intelligent m.nufacturing System. Laboratory Gifu UniversityJapan Departm.nt of Industrial Engineering University of Quebec at Trois-Rivers(UQTR)Canada

In this paper we propose a COncurrent Production Engineering System.（COPES） for the flexible transfer line （FTL） layout design in a restricted area. COPES first determ.nes the buffer size in front of the bay of each m.chine tool in the FTL and then initializes a com.uter aided design （CAD） system.to draw the FTL in a restricted area. We develop a set of m.dules system. which have been integrated into a single fram.work, in accordance with the practice of concurrent engineering. Concurrent engineering involves the cooperation of these activities. It＇s expected that the developed COPES can im.rove the cooperation between production engineers＇ and the plant designer. This can be done by enabling the production engineers＇ to m.ke better decision regarding FTL buffer size.

Three extraction m.thods, ultrasonic assisted extraction (USE), m.crowave assisted extraction (m.E), and conventional single extraction (CSE), in conjunction with the m.dified three-stage BCR sequential extraction procedure (SEP) were applied to exam.ne the contents of Cd, Cu, Cr, Ni, Pb and Zn from.lake sedim.nt sam.les, to know whether these techniques can reduce extraction tim. and im.rove reproducibility. The SEP and developed alternative single extrac- tion m.thods were validated by the analysis of certified reference m.terial BCR 601. By the use of optim.zed sonication and m.crowave conditions, steps 1, 2 and 3 of the BCR sequential extraction m.thods (excluding the hydrogen peroxide digestion in step 3, which was not perform.d with sonication and m.crowave) could be com.leted in 15-30 m.n and 60- 150 s, respectively. The recoveries of total extractable m.tal contents in BCR 601, obtained by three single extractions ranged from.93.3%-102%, 88.9%-104% and 81.2%-96.2% for CSE, USE and m.E, respectively. The precision of the single extraction m.thods was found in the range of 3.7%-9.4% for all m.tals (n = 6).

m.ddle Triassic carbonate sequences of Shotori Form.tion have a thickness of 70 m.and are deposited Robat-e-Kalm.rd region of Tabas city in Central Iran basin. Gradationally and conform.bly overlying Sorkh shale Form.tion, Shotori Form.tion, m.stly com.osed of m.dium.to thick dolom.tes (50 m., interbeded with thin lim. and sandstones, is disconform.ble by a laterite horizon at its upper boundary. This Form.tion m.inly consists of fine-to-coarsely crystalline dolom.tes. According to petrographic (fabric and grain size) and geochem.cal (elem.ntal analysis of Ca, m., Na, Sr, Fe, m.) evidence, five various types of dolom.tes were recognized in Shotori Form.tion. This variety results from.early and late diagenetic processes, triggering a change in dolom.tizing fluids and thereby form.ng various dolom.tes. Geochem.cal studies have revealed that the dolom.tes of Shotori Form.tion have form.d under m.teoric diagenesis and reducing conditions. Various dolom.tization m.chanism. are proposed for various types of dolom.tes;that is to say, Sabkha m.del is considered for type 1 dolom.te, m.xing zone m.del for type 2 and 3 dolom.tes and burial m.del for type 4 and 5 dolom.tes.

Use of Sewage Sludge After Lim.ng as Fertilizer for m.ize Growth

引用

Pedosphere 2008年第2期18卷 203-213页

作者： m.K.jamali T.G.KAZI m.B.ARAIN H.I.AFRIDI A.R.m.m.N N.JALBANI A.SHAH National Centre of Excellence in Analytical Chem.stry

The use of sewage sludge on agricultural land provides an alternative for its disposal. Therefore, the aim.of the present study was to evaluate the feasibility of using industrial sewage sludge produced in Pakistan, as an agricultural fertilizer. The agricultural soil am.nded with 250 g kg^-1 sewage sludge with or without lim. treatm.nt was used for the growth of the com.on local grain crop, m.ize （Zea m.ize）. The m.bility of the trace and toxic m.tals in the sludge sam.les was assessed by applying a m.dified BCR sequential extraction procedure. The single extraction procedure was com.rised of the application of a m.ld extractant （CaCl2） and water, for the estim.tion of the proportion of easily soluble m.tal fractions. To check the precision of the analytical results, the concentrations of trace and toxic m.tals in every step of the sequential extraction procedure were sum.ed up and com.ared with total m.tal concentrations. The plant-available m.tal contents, as indicated by the deionized water and 0.01 m.l L^-1 CaCl2 solution extraction fractions and the exchangeable fraction of the sequential extraction, decreased significantly （P 〈 0.05） with lim. application because of the reduced m.tal availability at a higher pH, except in the cases of Cd and Cu, whose m.bility was slightly increased. Sludge am.ndm.nt enhanced the dry weight yield of m.ize and the increase was m.re obvious for the soil with lim. treatm.nt. Lim.ng the sewage sludge reduced the trace and toxic m.tal contents in the grain tissues, except Cu and Cd, which were below the perm.ssible lim.ts of these m.tals. The present experim.nt dem.nstrates that lim.ng was an im.ortant factor in facilitating the growth of m.ize in sludge-am.nded soil.
