This study develops an optim.l perform.nce m.nitoring m.tric for a hybrid free space optical and radio wireless network, the Outage Capacity Objective Function. The objective function—the dependence of hybrid channel outage capacity upon the error rate, jointly quantifies the effects of atm.spheric optical im.airm.nts on the perform.nce of the free space optical segm.nt as well as the effect of RF channel im.airm.nts on the radio frequency segm.nt. The objective function is developed from.the basic inform.tion-theoretic capacity of the optical and radio channels using the gam.a-gam.a m.del for optical fading and Ricean statistics for the radio channel fading. A sim.lation is perform.d by using the hybrid network. The objective function is shown to provide significantly im.roved sensitivity to degrading perform.nce trends and supports of proactive link failure prediction and m.tigation when com.ared to current thresholding techniques for signal quality m.trics.

Autotherm.l reform.ng (ATR) is one of the leading m.thods for hydrogen production from.hydrocar- bons. Liquefied petroleum.gas, with propane as the m.in com.onent, is a prom.sing fuel for on-board hydrogen producing system. in fuel cell vehicles and for dom.stic fuel cell power generation devices. In this article, propane ATR process is studied and operation conditions are optim.zed with PRO/Ⅱ? from.SIm.CI for proton exchange m.m.rane fuel cell application. In the ATR system.including water gas shift and preferential oxidation, heat in the hot stream. and cold stream. is controlled to be in balance. Different operation conditions are studied and drawn in contour plots. The region for ATR reform.ng with the highest efficiency can thus be identified. One operation point was chosen with the following process param.ters: feed tem.erature for the ATR reactor is 425℃, steam.to carbon ratio S/C is 2.08, air stoichiom.try is 0.256. Therm.l efficiency for the integrated system.is calculated to be as high as 84.0 % with 38.27 % H2 and 3.2μl·L-1 CO in the product gas.

Objective: Onychom.cosis is a diagnosis of fungal organism. in the nail unit. It frequently occurs in both the im.unocom.etent and im.unocom.rom.sed patient. A variant of onychom.cosis is proxiam. onychom.cosis that occurs on the m.st proxim.l aspect of the nail. Proxim.l onychom.cosis is known to be com.only associated with im.unocom.rom.sed status. Study Design: A case report of a veteran who presented a derm.tology clinic with com.laint of solitary nail discoloration that was recalcitrant to over-the-counter therapy including topical hydrogen peroxide and foot soaks without im.rovem.nt. Results and Conclusions: This individual case report dem.nstrates that pedal proxim.l onychom.cosis can be associated with non-derm.tophyte organism., identified as Fusarium.species, in im.unocom.etent individuals. The finding of pedal proxim.l onychom.cosis caused by a Fusarium.non-derm.tophytic m.ld has not been reported. The veteran was successfully cured of the condition with treatm.nt via oral terbinafine for a ninety-day course while m.nitoring patient’s liver function test for any com.lications.

采用微波加热合成法制备了CoTm.P/BP电化学氧还原催化剂。采用旋转圆盘电极(RDE)研究了BP2000碳载体经30%H2O2或6m.l·L-1HNO3化学预处理后对催化剂氧还原催化活性的影响,并且在PEm.料电池工作站上测试了不同CoTm.P/BP催化剂的燃料电池单电池性能。结果表明,碳载体经过化学预处理后催化剂性能有显著的提高,并且30%H2O2处理效果更好。采用IR、XRD和XPS进一步分析了载体化学预处理对催化剂活性影响的机理:IR结果表明预处理后载体表面羟基(-OH)等含氧基团增多;XRD分析表明900℃热处理后催化剂中有Co3C(101)和金属态Co(111)结构出现;XPS分析表明碳载体预处理后N原子表面浓度以及组分N1和CoⅢ相对比例升高,有利于Co-N4-C活性位的形成,然而组分N1,O1sCoⅢ和CoⅡ的结合能(BE)有所下降。

Integrated observation platform. have been set up to investigate consequences of global change within a terrestrial network of observatories （TERENO） in Germ.ny. The aim.of TERENO is to foster the understanding of water, energy, and m.tter fluxes in terrestrial system., as well as their biological and physical drivers. Part of the Lower Rhine Valley-Eifel observatory of TERENO is located within the Eifel National Park. Recently, the National Park forest m.nagem.nt started to prom.te the nat- ural regeneration of near-natural beech forest by rem.ving a significant proportion of the spruce forest that was established for tim.er production after World War II. Within this context, the effects of such a disturbance on forest ecosystem.functioning are currently investigated in a deforestation experim.nt in the Wtistebach catchm.nt, which is one of the key experim.ntal re- search sites within the Lower Rhine Valley-Eifel observatory. Here, we present the integrated observation system.of the Wiistebach test site to exem.larily dem.nstrate the terrestrial observatory concept of TERENO that allows for a detailed m.n- itoring of changes in hydrological and biogeochem.cal states and fluxes triggered by environm.ntal disturbances. We present the observation platform. and the soil sam.ling cam.aign, as well as prelim.nary results including an analysis of data con- sistency. We specifically highlight the capability of integrated datasets to enable im.roved process understanding of the post-deforestation changes in ecosystem.functioning.

We determ.ned whether telavancin is as active in experim.ntal im.unocom.etent m.rine pneum.coccal pneum.nia as is vancom.cin or ceftriaxone. Experim.ntal m.rine pneum.nia was established by intratracheal adm.nistration of Streptococcus pneum.niae. Four groups of anim.ls were studied, untreated and treated with vancom.cin (110 m./kg, bid, SQ), telavancin (40 m./kg, bid, SQ), or ceftriaxone (50 m./kg, bid, SQ) for 2 days. The untreated anim.ls had a m.an of 6.54 ± 0.82 log10 cfu/g lung. The vancom.cin-, telavancin-, and ceftriaxone-treated anim.ls had m.ans of 2.01 ± 0.02, 2.00 ± 0.00, and 2.00 ± 0.01 log10 cfu/g lung, respectively (p-values m.nt group versus the untreated group). In the m.del studied, telavancin was as active as vancom.cin and ceftriaxone in treating experim.ntal pneum.coccal pneum.nia in m.ce.

One of the inputs required by daily decision support tools for scheduling irrigation is the am.unt of water supplied by rainfall. In-field m.asurem.nts of daily precipitation are expensive or laborious, while m.asurem.nts from.gauges within a few kilom.ters are frequently not representative due to the high spatiotem.oral variability of precipitation. Online radarbased precipitation analyses from.NOAA’s National Weather Service (NWS) have obvious potential to provide the needed data, but are known to have varying degrees of accuracy with location and conditions. The NWS precipitation analysis is com.uted on a 4 km.× 4 km.grid, so differences should also be expected between the product and individual gauge m.asurem.nts under each grid cell. In order to test the utility of the NWS precipitation analysis in a daily irrigation scheduler, daily data were gathered in July 2012 from.18 weather stations under 2 NWS precapitation analysis grid cells across instru-m.nted research and production fields in the m.ssissippi Delta. Differences between individual station m.asurem.nts and the NWS precipitation analysis are exam.ned, and root-zone daily soil water deficits com.uted using both station data and the NWS precipitation analysis. Sub-grid spatial variability between gauge locations, and differences in precipitation between gauges and the gridded NWS analysis, are found to be sim.lar to those reported elsewhere. Differences between tim. series of soil water deficit com.uted using the two different precipitation data sources are noted, but prove to be of lim.ted im.act on the decision to irrigate or not to irrigate. It is also noted that profile-filling rainfalls lim.t the im.act of accum.lating error, resetting the m.deled soil water to “full”. Given the Delta-local practice of irrigating to replace full evapotranspirational water used, use of the NWS daily precipitation analysis data as input for a daily irrigation scheduler is judged not only acceptable, but also preferabl

Soil arthropods play an im.ortant role in nutrient cycling and m.intenance of soil structure, and their abundance and diversity provide an indication of the biological quality of soil. Land application of livestock m.nure provides crop nutrients and m.y also im.act the soil arthropod com.unity. This study was conducted to quantify soil arthropod abundance and diversity for a period of one year following swine m.nure application via broadcast or injection. Arthropods were extracted from.plot soil sam.les using Berlese funnels, identified and counted, and the QBS index (Qualità Biologica del Suolo) was calculated for each soil sam.le. Collem.ola (Hypogastruridae and Isotom.dae) populations were greater (p p in the injection treatm.nt com.ared to the broadcast and control treatm.nts. Acari populations and the QBS index were not significantly im.acted by m.nure application.
