No full textWeb Services (WS) have emerged as a new component-based software develop-ment paradigm in a network-centric environment based on the Service-Oriented Architec-ture (SOA), the XML open standard description language, and HTTP transportation pro-tocol. Legacy software systems can incorporate WS technology in order to be reused and integrated in a distributed environment across heterogeneous platforms. While WS is gaining its momentum toward wide adoption in the software industry, there are two criti-cal issues yet to be addressed before its power is fully realized: (1) the migration of leg-acy distributed software systems toward WS applications and (2) the innovation of new infrastructures and languages in support of WS application development. The contribu-tion of this dissertation is in these two directions. First, a comprehensive, systematic, automatable, and language-neutral approach is presented toward reengineering legacy software systems to WS applications, rather than rewriting the whole legacy software system from scratch in an ad hoc, language-specific manner. It is noteworthy that this approach is not specific to reengineering WS applica-tions but can be generalized to reengineering legacy software systems to other applica
Insights into the Kinetics, Theoretical Model and Mechanism of Free Radical Synergistic Degradation of Micropollutants in UV/Peroxydisulfate Process
No full textThe degradation of acyclovir (ACY) and atenolol (ATL) in the UV/peroxydisulfate (UV/PDS) process has been systematically considered, focusing on the degradation kinetics, theoretical models, and reaction pathways via applying a microfluidic UV reaction system. The removal efficiencies of ACY and ATL were >94.8%, and the apparent degradation rate constants (kobs) were 0.0931 and 0.1938 min−1 at pH 6.0 in the UV/PDS system. The sulfate radical (SO4•−) and hydroxyl radical (•OH) were identified as the major reactive radicals. The pH-dependent reaction rate constants of ACY and ATL with •OH and SO4•− were measured via the competing kinetics. Meanwhile, the contributions of •OH and SO4•− for ACY and ATL degradation were calculated by the radical steady-state hypothesis, and the results revealed that SO4•− occupied a decisive position (>84.5%) for the elimination of ACY and ATL. The contribution of •OH became more significant with the increasing pH, while SO4•− was still dominant. Moreover, ACY and ATL degradation performance were systematically evaluated via the experiments and Kintecus model under different operational parameters (Cl−, Br−, HCO3−, NOM, etc.) in the UV/PDS process. Furthermore, the plausible reaction pathways of ACY and ATL were elucidated based on the Fukui function theory and ultra-performance liquid chromatography-tandem quadrupole time-of-flight mass spectrometry (UPLC-QTOF-MS) analysis. The UV/PDS process has been demonstrated to be an efficient and potential application for micropollutants mitigation

Voltammetric Determination of Acyclovir in Human Urine Using Ultra Trace Graphite and Glassy Carbon Electrodes
Full text linkAn electroanalytical method was developed for the direct quantitative determination of Acyclovir (Acy) in spiked human urine base on its oxidation behavior. The electrochemical oxidation and determination of Acy were easily carried out on ultra trace graphite electrode (UTGE) and glassy carbon electrode (GCE) using a variety of voltammetric techniques. The electrochemical measurements were carried out on these electrodes in various buffer solutions in the pH range of 3.66 to 9.08 by cyclic voltammetry (CV) and differential pulse voltammetry (DPV) techniques. The best results for the quantitative determination of Acy were obtained by DPV technique in 0.2 M acetate buffer (pH=4.66). In this acidic medium, one irreversible anodic peak was observed. The anodic peak current and peak potential depend on pH and scan rate were studied. The diffusion controlled nature of the peak was established. Acy was determined in the concentration range from 4x10(-6) to 7x10(-5) molL(-1) for UTGE and 2.0x10(-6) to 1.0x10(-4) molL(-1) for GCE by the applied electroanalytical procedure. Limit of detection (LOD) and limit of quantification (LOQ) were obtained as 1.0x10(-6) and 3.3x10(-6) molL(-1) on UTGE and 3.5x10(-7) and 1.2x10(-6) molL(-1) on GCE, respectively. Repeatability, precision and accuracy of the developed technique were checked by recovery studies in spiked urine.Scientific and Technical Research Council of Turkey (TUBITAK) [TBAG-2173, 102T062]The author gratefully acknowledges to the Scientific and Technical Research Council of Turkey (TUBITAK, Grant No: TBAG-2173; 102T062).

[[alternative]]Identification and physiological characterization of extracellular lipase producing bacteria isolated from the sewage
No full text[[abstract]]Three bacteria strains (I3a, II11 and II11') were isolated from the sewage by using a Mg medium which contained butter as the sole carbon source. Thesethree strains were identified as namely; Pseudomonas aeruginosa, Aeromonashydrophila and Acinetobacter baumanii. They were observed under the dark fieldmicroscope as morphologially rod-sheped, and their sizes examined were smallerthan E. coli. So, they were further identified and examined in more detail with electron microscope. The highest amount of lipase produced by P. aeruginosa I3a is at 30C, and itsoptimal growth pH is around 7. With p-nitrophenyl esters as its substrates, theenzyme shows a preference for C12 acy group. The enzyme activity was inhibited byHg2+ and Mn2+, but did not significantly affect by the Mg2+ and Ca2+. The highest amount of lipase produced by A. hydrophila II11 is at 30C, and they produced lipase better at pH6-pH8, this enzyme shows no preference for anysubstrate. The enzyme activity was inhibited by Hg2+, and not affect by Ca2+ andMn卻有促進作用. The highest amount of lipse produced by Acineto. baumanii II11' is at 37C, but30C is the optimal growth temperature. Its optimal pH of lipase producing is 8. The enzyme shows a preference for C4 acy group. The enzyme activity was inhibitedby Hg2+, Mg2+, and Mn2+, but did not significantly affect by the Ca2+. In classification, P. aeruginosa I3a is aerobes, A. hydrophila II11 is facutauiveanaerobes, and Acineto. baumanii II11' is aerobes. They possess alkaline lipases,however their optimal pH of lipase production are different. Besides, sensitivityof three enzyme to various temperatures are different.

Asclerobia alexandrae sp. nov. is characterized by the yellowish-grey forewing with a bright yellow ante-medial line edged with grey-brown raised scales proximally. The ante-medial line in A. sinensis is edged inwardly with yellowish-red raised scales, and with bright brown raised scales in A. tchahabarella. Middle segments of male antenna are almost square, 1.3× as wide as long in the new species (Fig. 19), but 2× as wide as long in A. sinensis (Fig. 20c). In male genitalia of a new species the apex of the saccus is almost truncate (angulate on sides). In related species (A. sinensis and A. tchahabarella) the saccus is rounded apically. The female genitalia of the new species are recognizable by a long segment VIII, which length is 2.2× its width, and long, straight papillae anales. In A. sinensis the length of segment VIII is 1.5× its width, papillae anales laterally have recess, shorter. Furthermore, the total length of the female genitalia (when fully extended posterior apophyses) is 7 mm in A. alexandrae sp. nov. in contrast to 5 mm in A. sinensis, of equally sized specimens (in this example 20 mm of wingspan). Description. Adult (Figs 1, 2, 7–19): wingspan 15.5–19.5 mm (♂♂), 14.5–23.5 mm (♀♀). Head, tegulae, patagium, thorax, labial palpus and antennae from light yellow to light or dark grey, thorax often darker. Labial palpus straight, approximately 2.5× as long as the diameter of the eye. Antennae in males filiform, flattened, covered with very short sparse hairs that are distinguishable only at high magnification (over 30×), with an unstable quantity, more often 4–6 barbs on 3–5 segments (Fig. 19); the barbs are formed by special strong scales, which can come off; sinuses are absent. The antennae of females less flattened, segments are almost square. Ground colour of the forewing from light yellow to dark grey. Ante-medial line bright yellow with grey-brown raised scales proximally. A black discal spot (or double discal spot) at 2/3 length on forewing. Hindwing grey, marginal line dark grey. Fringes of both fore- and hindwings grey. Abdomen grey-yellow. Legs light grey. Variation. In yellow specimens the basal area of forewings, apex and sometimes costa are grey. Male genitalia (Figs 27–29): uncus nearly as long as broad at base, gradually narrowed towards sharped apex, having the shape of an almost isosceles triangle. Gnathos 2× shorter than uncus, tapers towards a pointed and curved apex. Tegumen subrectangular, tapering in the distal half, with distinct transition to uncus, up to half the length has lobes on the sides. Valva parallel-sided at base, the remaining 2/3 narrowed. Cucullus pointed, weakly sclerotized, coveredwith shortdense setae. Costaseverely sclerotized, tapersevenly towards apex, with a characteristicelongated editum on 1/3 its length, the base of which is 2× the length. Sacculus strongly sclerotized, tapers evenly towards the apex, on average 1.6× less than the length of the costa. Juxta V- or U-shaped, proximally rounded, tips rounded and covered with long setae. Vinculum elongated, 1.4× longer than width at base, narrowing sharply to 2/3, where it has the narrowest point, then expands slightly again, the apex of the saccus almost truncate. Aedeagus wide, extends to the middle of tegumen, with a wide D-shaped false cornutus, which almost 2.5× shorter than the aedeagus. Culcita 1.3× as long as wide, with X-shaped sclerotization and with scale tufts, 1.5× longer than the length of culcita. Variation. The shape of the editum varies considerably (Figs 27a, 28a, 29a). Female genitalia (Figs 21–23): papillae anales subtriangular, sparsely covered with long hairs. Posterior apophyses straight, very long, on average 7× as long as the papillae anales. Anterior apophyses 1.7× shorter than the posterior apophyses and 4× as long as the papillae anales. Segment VIII on average 2.2× as long as wide, posterior margin straight; tergum VIII with a longitudinal, not sclerotized medial zone in the anterior half of the segment, anterior margin rounded; sternum VIII with broad anteromedial emargination. Ductus bursae as long as the apophyses anteriores, broad. Antrum of the same width as the segment VIII, short, ventrally sclerotized. Bursa copulatrix egg-shaped with distinct transition to ductus bursae, ductus seminalis and ductus bursae depart from the same side. The base of the ductus seminalis wide, evenlytapering distally, with a funnel-shaped sclerotization, which with an oblong process at the base. Bursa copulatrix with a semicircular cord consisting of spike-like signae. Variation. Anterior margin of tergum VIII varies from rounded to oviform, sometimes the edge is not evenly convex (Figs 21–23). Biology. According to label data, the specimens of the new species were collected on mountain steppes and sands by shaken off the bushes of Caragana bungei Ledeb., which is possible the host-plant of the larvae. The specimens from the type series were observed in late May and mid-June at an altitude of 1000–1100 m (vic. of Erzin and Altan-Els sands) and 1800–2100 m (vic. of Mugur-Aksy, Eastern Tannu-Ola mountain range). Remarks.All 37 dry female specimensof the newspecies have the terminal partof the female genitalia (segment VIII and ovipositor) more or less distinctly protruded from the end of abdomen. It is unclear, if it is the natural state for this species or just a result of applying of the killing agent. Distribution. Russia: Tyva Republic. Etymology. The new species is named in honour of Alexandra Kiryazieva, an amazing and wonderful woman, good friend, classmate and the author`s first love. Note. Type locality of the new species is the vicinity of Mugur-Aksy village (Mongun-Tayginsky district of Tyva Republic, 50°22’51”N, 90°25’59”E). However, the name “Mugur-Aksy” belongs not only to the village, but also to several tracts located in its vicinity at a distance of 3–17 km and an altitude of 1800–2000 m at the foot of the southern slope of the Tsagan-Shibetu mountain range. It is not clear from the labels where exactly the specimens from the type series (including the holotype) have been collected.Published as part of Yepishin, Viktor, 2021, Notes on the taxonomy of Palaearctic Asclerobia Roesler, 1969 (Lepidoptera Pyralidae: Phycitinae) with description of a new species, pp. 149-162 in Zootaxa 4963 (1) on pages 151-152, DOI: 10.11646/zootaxa.4963.1.7, http://zenodo.org/record/471998
