Type material: IOZ-CAS (holotype), paratypes in IOZ-CAS and PHMBL according to Melika et al. (2004). Distribution. Mainland China (Yunnan province, according to Melika et al. (2004) and Zhejiang province, according to Wang et al. (2010)). Also, from South Korea and Japan (Schwéger et al. 2015b: 62, Saphonecrus connatus section). ......continued on the next page * Quercus sections have been assigned following http://oaks.of.the.world.free.fr/liste.htm [Last entry date: July 2020] Biology. Unknown (Melika et al. 2004). According to Schwéger et al. (2015b), reared from leaf galls on Quercus dentata based on the notes about Saphonecrus connatus made by Sakagami (1949) and Abe et al. (2007). Remarks. Saphonecrus connatus is thought to be a trans-Palaearctic species and was recorded from Japan and South Korea (Sakagami 1949; Abe et al. 2007). However, these records may possibly be Saphonecrus chaodongzhui, a species that is closely related to S. connatus, according to Melika et al. (2004) (Schwéger et al. 2015b).Published as part of Lobato-Vila, Irene, Kang, Minjoon, Roca-Cusachs, Marcos, Kim, Ilkwon, Jung, Sunghoon & Pujade-Villar, Juli, 2020, Taxonomic assessment of the inquiline fauna (Hymenoptera: Cynipidae Synergini, Ceroptresini) reared from cynipid galls on oaks (Quercus spp.) from South Korea, pp. 179-198 in Zootaxa 4860 (2) on pages 182-185, DOI: 10.11646/zootaxa.4860.2.2, http://zenodo.org/record/441368

Integration of simulated moving bed chromatography and enzymatic racemization for the production of single enantiomers
No full textIntegration of enantioseparation by simulated moving bed (SMB) and mild enzymatic racemization enables the production of single enantiomers from a racemic mixture in theoretically 100% yield and hence overcomes the 50% yield limitation of conventional SMB processes. We implemented such a process consisting of a Chirobiotic TAG column-SMB, an amino acid racemase-containing enzyme membrane reactor, and a nanofiltration unit for concentration of the distomer-enriched SMB raffinate prior to racemization on lab-scale for the production of enantiopure D-methionine. The integrated process scheme was operated continuously for over 30 h without significant variations in product concentration and purity and with a yield of 93.5%, demonstrating the feasibility of this integrated process concept. Furthermore, a rational analysis of the integrated process on the basis of a short-cut model was conducted. The process model consists of a true moving bed equilibrium stage model to represent the SMB, a continuous stirred tank reactor model with reversible Michaelis–Menten kinetics to represent the enzyme membrane reactor, a nanofiltration model and feed node mass balances, and enabled the identification of optimal operating points (flow rate ratios, enzyme concentration) at a variety of process specifications and objectives. Optimal operating points were calculated for different cost distributions between the applied materials such as stationary phase, enzyme, solvent, and nanofiltration membrane. By assigning plausible pricing data and lifetimes to the respective materials, variable costs for the specific process considered in this work were estimated
Synergus chinensis Melika, Acs & Bechtold 2014
No full textSynergus chinensis Melika, Ács & Bechtold, 2014 Figs 123–133 This species was described from north-eastern China (Beijing Province, Mentougou District, 150 km NW of Beijing), reared from unknown cynipid acorn, leaf and bud galls (Melika et al. 2004). It was later found by one of the authors (GM) in South Korea (Abe et al. 2007). Kovalev (1965) mentioned S. gallaepomiformis (Boyer de Fonscolombe) for the Far East of Russia, which was reared from asexual galls of Andricus hakonensis (= A. symbioticus, = A. attractus). We strongly doubt this identification. On the basis of the adult description given by Kovalev, these specimens belong to S. chinensis (Abe et al. 2007). Synergus chinensis falls into a subclade with S. symbioticus and can be easily distinguished from the latter by some strong diagnostic characters given in the key and in the Diagnosis to S. symbioticus. Currently known from China, South Korea and Russia.Published as part of Schwéger, Szabina, Melika, George, Tang, Chang-Ti, Bihari, Péter, Bozsó, Miklós, Stone, Graham N., Nicholls, James A. & Pénzes, Zsolt, 2015, New species of cynipid inquilines of the genus Synergus (Hymenoptera: Cynipidae: Synergini) from the Eastern Palaearctic, pp. 451-497 in Zootaxa 3999 (4) on page 485, DOI: 10.11646/zootaxa.3999.4.1, http://zenodo.org/record/24368
Diffusive author(s), cohesive author: Analysis of S/N (1994)
No full textThis study indicates the ways in which various aspects of the author(s) are brought forth in Dumb type’s performance art, the S/N production. Previous research has suggested a non-hierarchical organization of Dumb type and the absence of a “privileged author” in Dumb type’s collaborative work, S/N. However, the results that I have investigated from member’s interviews on the creative process of S/N along with my analysis of the recorded images of S/N, indicate a different aspect of the author(s). First, S/N was created through, so to speak, the collective ideas of the members of Dumb type. Further, S/N has at least nine quotations from previous performances, installations, and printed writings, besides the work-in-progress technique. Explicating one of the “author functions” as given by Michel Foucault, each text has plural subjects of the author. However, it has been revealed from members’ interviews that Teiji Furuhashi had a decision-making role in selecting the members’ ideas within the performance. Since then, S/N has had plural subjects of creation; however, Furuhashi is one of the subjects of creation along with the “privileged author.” S/N has plural authors (diffusive authors) yet at the same time, it has a “privileged author,” Teiji Furuhashi (cohesive author)
Synergus xialongmeni Melika, Acs & Bechtold 2004
No full textSynergus xialongmeni Melika, Ács & Bechtold, 2004 Figs 134–144 Currently known only from China (Beijing Province, Mentougou District, 150 km NW of Beijing), reared from unknown cynipid acorn, leaf and bud galls (Melika et al. 2004). This species, together with S. belizinellus and S. ishikarii, forms a distinct subclade and morphologically with all three species show some similarity. Diagnostic characters for all three species are given in the key and also in the Diagnosis to S. ishikarii and S. belizinellus. Based on this research we can conclude that there are currently 17 valid species of Synergus in the Eastern Palaearctic, and two species with an uncertain status (Table 2). Total: 17 valid species and 2 with uncertain statusPublished as part of Schwéger, Szabina, Melika, George, Tang, Chang-Ti, Bihari, Péter, Bozsó, Miklós, Stone, Graham N., Nicholls, James A. & Pénzes, Zsolt, 2015, New species of cynipid inquilines of the genus Synergus (Hymenoptera: Cynipidae: Synergini) from the Eastern Palaearctic, pp. 451-497 in Zootaxa 3999 (4) on page 491, DOI: 10.11646/zootaxa.3999.4.1, http://zenodo.org/record/24368
Saphonecrus naiquanlini Melika, Acs and Bechtold 2004
No full textSaphonecrus naiquanlini Melika, Ács and Bechtold, 2004 Saphonecrus naiquanlini Melika, Ács and Bechtold in Melika et al. (2004). Acta Zool. Hung. 50: 334. Type material: IZCAS (holotype), paratypes in IZCAS and PHMBL. Diagnosis: Saphonecrus naiquanlini belongs to a group of species (S. shanzhukui, S. shirakashii and S. shirokashicola) characterized by having lateral pronotal carina and tarsal claws with a basal lobe. It differs from S. shirokashicola by the malar space being 0.6x as long as height of eye (0.5 in S. shirokashicola), POL 2.5x as long as OOL (2.0 in S. shirokashicola), notauli complete (incomplete, short, in S. shirokashicola) and female syntergite dorsodistally incised (not incised in S. shirokashicola). It differs from S. shirakashii by the transfacial distance being as long as height of eye (longer in S. shirakashii), POL 2.5x as long as OOL (3.0 in S. shirokashii) and mesoscutum with weak interrupted transversal carinae (delicately coriaceous to alutaceous in S. shirakashii). Lastly, it differs from S. shanzhukui by the malar space being 0.6x as long as height of eye (0.7 in S. shanzhukui), the vertex delicately coriaceous with very weak, delicate dense transverse rugae (alutaceous to smooth in S. shanzhukui), and OOL slightly longer than diameter of lateral ocellus (1.6 in S. shanzhukui). See also the key to species below. Distribution: Mainland China. Zhejiang Province (Melika et al. 2004; Wang et al. 2010). Biology: Unknown (Melika et al. 2004; Wang et al. 2010). Remarks: According to both the original description and drawings given in Melika et al. (2004: 332, 334), this species has the speculum smooth and shining, without striae, and POL 3.5x as long as OOL. However, the photos of one of the paratypes of S. naiquanlini provided by Schwéger et al. (2015b: 69) reveal that the speculum is completely striate, and that POL is at most 2.5x as long as OOL. Other differences observed between the photos provided by Schwéger et al. (2015b) and the original description are that the malar space is 0.6x as long as height of eye (0.5 in the original description) and F11 is almost 2.0x as long as F10 (1.3 in the original description). Furthermore, S. naiquanlini is keyed out twice in the morphological key provided by Schwéger et al. (2015b: 12): one for specimens measuring more than 2.5 mm in length and with the mesoscutum strongly transversely carinate, and the other for specimens spanning from 1.3–2.0 mm in length and with the mesoscutum coriaceous, without or with weak carinae. This species shows no size nor sculptural variability, with all the specimens belonging to the type series being 2.0 mm long and having the mesoscutum weakly carinate, according to the original description; so, the option for larger specimens with a stronger sculpture in the key is incorrect.Published as part of Lobato-Vila, Irene, Wang, Yiping, Melika, George, Guo, Rui, Ju, Xiaoxue & Pujade-Villar, Juli, 2021, A Taxonomic Review of the Gall Wasp Genus Saphonecrus Dalla-Torre and Kieffer and other Oak Cynipid Inquilines (Hymenoptera: Cynipidae) from Mainland China, with Updated Keys to Eastern Palaearctic and Oriental Species, pp. 1-25 in Zoological studies (Zool.
