Holotype and paratype are stored in ethanol and deposited in MZL; lllies, 1966: 389 (Skobeleva irani); Zwick, 1973: 229 (Filchneria irani); Sartori et al., 1990: 170 (Filchneria irani); Zwick, 1997: 495, fig. 7d (Filchneria irani); Mohammadian, 2008: 113–115, (Perlodes(Skobeleva) irani). Diagnosis. The male of F. irani is distinguished by the shape of the posterior margin of tergum 10, which is slightly elevated and its top smoothly rounded; the paraproctal sclerite is triangular and heavily sclerotized basally and along the outer edge, sclerotization narrowed distally, and indistinct at the apex. The female has a wide and short subgenital plate, its posterior margin slightly serrated; the lobes are poorly expressed, each lateral edge bears a small rounded protrusion directed to the side. Complementary description. Adult habitus. Color pattern of male and female on the head and pronotum is similar(Figs. 16,17, 20).Head is brown with pale spots.Most parts of clypeus are covered with a semicircular brownish spot; anterior edge, paired small spots on lateral clypeal margins near M-line bases, and small butterfly-shaped spot in front of anterior ocellus are pale. M-line brown, interocellar area brown, with a rather narrow longitudinal pale stripe slightly widened posteriorly. Occiput with transverse pale band extends along the epicranial stem and compound eyes (Figs. 16, 17, 20); a narrow and short black band surrounds each compound eye posterolaterally. Pronotum brown with pale median band widened posteriorly, anterior corners bear small pale spots, the pronotal rugosities are dark brown, sometimes indistinct (Figs. 17, 20). Male. Holotype. Brachypterous, wings not exceeding tergum 2 (Fig. 16). Coloration of abdominal terga corresponds to original description: large, yellowish quadrangular spot on sides of brown median line of terga 1–7 (Fig. 16). Dark medial line is obscured on terga 8–9, tergum 10 entirely yellowish. Tergum 7 bears two patches of sensilla basiconica on sides of dark medial line posteriorly; tergum 8 densely covered by sensilla basiconica posteromedially; the sensilla basiconica are also present on tergum 9, but they are solitary and scattered closer to the posterior tergal margin (Fig. 18). Posterior margin of tergum 10 slightly elevated, top smoothly rounded, dorsal surfaces covered with sensilla basiconica in the middle (Figs. 18, 19). Paraproct is triangular, wide at the base and narrowed to the apex. The paraproctal sclerite triangular, heavily sclerotized basally and along outer edge, narrowed to the apex, and indistinct; sclerotization along outer sclerite edge serrated, (Fig. 19); inner edge of paraproct is pale and membranous distally. Female. Paratype. Macropterous. Sternum 8 is dark brown in the anteromedian half, bears a pair of oblique, dark brown lateral sclerites surrounding a subgenital plate anterolaterally (Fig. 21). Subgenital plate wide and short, covering about one third of sternum 9; the posterior margin with a slight notch in the middle; the lobes are poorly expressed, enclosed with tiny, brown setae; each lobe at the lateral edge with a small, rounded, lateral protrusion, posterior half of subgenital plate brownish (Fig. 21). Sternum 9 is pale medially, with pair of rounded dark brown spots laterally extending to curve brown bands directed upward under the subgenital plate (Fig. 21). Sternum 10 pale with two small brown spots laterally. Paraprocts are triangular in shape, rounded at the apex. Egg. According to P. Zwick (1997) the egg measures 430×300 μm. Egg has almost parallel lateral margins before anterior pole, the anterior pole is arcuate, posterior one truncated, pedicel very short, the anchor plate flat, pan-shaped (Fig. 22). The chorion is not distinctive. Material examined. Holotype male, paratype female: Iran, prov. Ostan, Chaîne de l'Elbourz, Polur, 2800 m, 10.V. 1956. F. Schmid leg. (MZL). Distribution. Filchneria irani was collected by F. Schmid in northern Iran (Aubert 1964), in Polur village which is situated on the Haraz River in Mazandaran Province. The Haraz River originates from the east slope of Mount Damavand (5610 m asl), Central Elburz (Alborz) Mountain Range and flows in a relatively narrow valley into the Caspian Sea. Schmid has collected material until altitude 2800 m asl. This is the only record of F. irani, an apparently rare species, which is considered an endemic of the Elburz Mountains (Mohammadian 2008).Published as part of Teslenko, Valentina A. & Palatov, Dmitry M., 2023, Redescription of a few Filchneria Klapálek, 1908 (Plecoptera, Perlodidae) species on the type and fresh material, pp. 287-312 in Zootaxa 5277 (2) on pages 292-295, DOI: 10.11646/zootaxa.5277.2.3, http://zenodo.org/record/788983

Microtus irani Thomas 1921
No full textMicrotus irani Thomas, 1921 Microtus irani Thomas, 1921: 580. COMMON NAME. — Iranian Vole. HOLOTYPE. — Not traced. TYPE LOCALITY. — Bagh-i-Rezi, Shiraz, Fars Province, 5200 ft. DISTRIBUTION. — As currently recognized, this taxon is not endemic to Iran, however it probably should be retained due to the uncertainy of its distribution (Kryštufek 2017a, b) (C. William Kilpatrick comm. pers.). Kock et al. (1972) and Kock & Nadler (1983) expanded the range of this species to extend from Western Iran to Israel, a distribution perpetuated by others including Musser & Carleton (1993). Kryštufek & Kefelioğlu (2001) redescribed M. irani based on the holotype and three topotypes and restricted its known distribution back to the type locality. However, analysis of cytochrome b (Cytb) sequences (Kryštufek et al. 2009) suggested that M. irani also occurred in Balkusan, Turkey; and Kryštufek et al. (2010) recognized this taxon as a new subspecies (M. i. karamani). The range of M. i. karamani has been expanded to include Lebanon (Kryštufek et al. 2013) and western Iran (Mahmoudi et al. 2014). HABITAT. — Steppe in mountains, grasslands with clumps of bushes, cultivated fields, and orchards at elevations of 1000-2100 m (Kryštufek & Kefelioğlu 2001; Kryštufek 2017a). IUCN. — Data deficient. REFERENCES. — Thomas (1921); Ellerman (1948); Kock et al. (1972); Kock & Nadler (1983); Musser & Carleton (1993); Kryštufek & Kefelioğlu (2001); Kryštufek et al. (2009, 2010, 2013); Mahmoudi et al. (2014); Kryštufek (2017a). REMARK Included in M. sociialis (Pallas, 1773) by Lay (1967) following Ellerman (1948). Currently this taxon is proposed to contain three subspecies (irani Thomas, 1921, karamani Kryštufek, Vohralík, Zima, Koubinová & Bužan, 2010, and schidlovskii Argyropulo, 1933) with a distribution including areas of Iran, Iraq, Turkey, Lebanon, Syria, Georgia, and Armenia. However, the taxonomic scope and the distributions of these taxa are still poorly understood (Kryštufek 2017a).

Modeling adhesive contacts under mixed-mode loading
No full textExperiments show that when an adhesive contact is subjected to a tangential load the contact area reduces, symmetrically or asymmetrically, depending on whether the contact is under tension or compression. What happens after the onset of sliding is more difficult to be assessed because conducting experiments is rather complicated, especially under tensile loading. Here, we provide through numerical simulations, a complete picture of how the contact area and tractions of an adhesive circular smooth punch evolve under mixed-mode loading, before and after sliding. First, the Green's function molecular dynamics method is extended to include the description of the interfacial interactions between contacting bodies by means of traction–separation constitutive laws that enforce coupling between tension (or compression) and shear. Next, simulations are performed to model sliding of a circular smooth punch against a flat rigid substrate, under tension and compression. In line with the experimental observations, the reduction in the contact area during shear loading is found to be symmetric under tension and asymmetric under compression. In addition, under tensile loading, full detachment is observed at the onset of sliding with a non-zero value of the tangential force. After the onset of sliding and the occurrence of slip instability, the contact area abruptly increases (reattachment), under both tension and compression. For interfaces with high friction, the reattachment occurs only partially. However, a full reattachment is attainable when friction is low.(OLD) MSE-
Electronic transformation of government in the U.K.: a research agenda
No full textThis paper presents the findings of an exploratory research project into future
e-Government (electronic Government) initiatives. The Virtual Institute for
Electronic Government Research (VIEGO) project aimed at identifying and
further developing the research agenda of e-Government based on a solid
practical ground. As such, the paper offers a novel methodology in identifying
the road map for future e-Government initiatives based on a series of
workshops organised around the U.K. hosting a mixture of stakeholders
involving both academics and parishioners. The analysis of the VIEGO
workshops depicted that an e-Government research agenda involves a
combination of social, technological and organisational issues at both
governmental and individual citizen level, ultimately driven by empirical
case-based experience and active participation in e-Government processes.
Unlike other propositions for the future of e-Government offered in the e-
Government literature, raised research questions not only originated from an
analysis of e-Government literature but also on the outcome of brainstorming,
reflections and contemplations throughout the duration of the project

The extracted specimen is kept in the IBE with the same reference number.</p> <p> <b>Differential diagnosis.</b> 1.8–2.0 mm long. Habitus and coloration as in Fig. 1. Externally, the new species resembles <i>O. khuzestanicus</i> (Iran) and <i>O</i>. <i>wurayah</i> Jäch & Delgado (UAE). It differs from these species in the less coarsely granulate elytra, and from <i>O. khuzestanicus</i> also in the less densely punctate pronotum. Head and pronotum of <i>O</i>. <i>hivae</i> are usually more distinctly cupreous than in the two other species.</p> <p> In <i>Ochthebius puberulus</i>, which is obviously closely related with <i>O. khuzestanicus</i> and <i>O</i>. <i>wurayah</i> the elytra are not granulate.</p> <p> Aedeagus (Figs. 2 –3): distal lobe 370?400 µm long. It differs quite significantly from the three species mentioned above (see Jäch 1989, Jäch & Delgado 2010). Its distal lobe does not possess a long, strongly curved tube-like process. The distal lobe of the new species vaguely resembles <i>O</i>. <i>rectilobus</i> Jäch, 1989 (see Jäch 1989: Fig. 23) and <i>O</i>. <i>decianus</i> Orchymont, 1942 (see Jäch 1999: Fig. 19). However, the aedeagus of the new species is definitely longer and the distal lobe is wider. The distal lobe of <i>O. schoedli</i> Jäch, 1999 (see Jäch 1999: Fig. 18) is also somewhat similar but it is characterized by a subacute prominence on the dorsal margin, which is absent in the new species.</p> <p> <b>Sexual dimorphism</b>: Anterior margin of male labrum slightly upturned. Explanate margin of elytra of females wider than in males. Abdominal apex of female with blunt spines.</p> <p> <b>Variability.</b> Postocular emargination of pronotum and postocular tooth weakly or well developed. The density of the pronotal punctation also varies to some extent.</p> <p> Remarkably, the width and the outlines of distal lobe of <i>Ochthebius hivae</i> are very variable, even within the same population (see Fig. 3).</p> <p> <b>Discussion.</b> In most species of the <i>Ochthebius metallescens</i> group there is hardly any aedeagal variability. Thus the extraordinary variability of the shape of the distal lobe of <i>O. hivae</i> can be regarded as rather exceptional in this group. The specimen from Khairabad River is particularly devious, but there is little doubt that it belongs to the same species.</p> <p> <b>Distribution.</b> The new species is known from western Iran (Ilam Province and southeastern Khuzestan Province).</p> <p> <b>Etymology.</b> We take pleasure in naming this species for Hiva Naserzadeh (Insect Taxonomy Research Department, Iranian Research Institute of Plant Protection, Tehran, Iran), who collected the first specimens of this species in 2007.</p>Published as part of <i>Jäch, Manfred, Irani, Elham & Delgado, Juan A., 2013, Ochthebius hivae (Coleoptera: Hydraenidae) from western Iran, a new species of the O. metallescens group with remarkable aedeagal variability, pp. 195-199 in Zootaxa 3700 (1)</i> on pages 195-198, DOI: 10.11646/zootaxa.3700.1.9, <a href="http://zenodo.org/record/218203">http://zenodo.org/record/218203</a>
The Iranian vole Microtus irani occurs in Lebanon (Mammalia: Rodentia)
No full textWe studied 1140 bp cytochrome b sequences of social voles from three localities in Lebanon. The results were compared with published sequences representing seven species of social voles. New sequences from Lebanon clustered with reference samples of two species: M. guentheri and M. irani. While M. guentheri was already reported for Lebanon, M. irani is a new addition to the fauna of Lebanon, and the third known record for the species. Animals were collected in two localities above Tripolis at 855 m and 1430 m a.s.l., respectively. © Zoology in the Middle East, 2013.Anisimova M, 2006, SYST BIOL, V55, P539, DOI 10.1080-10635150600755453; Corbet G.

Developing a frame of reference for ex-ante IT/IS investment evaluation
No full textInvestment appraisal techniques are an integral part of many traditional capital budgeting processes. However, the adoption of Information Systems (IS) and the development of resulting infrastructures are being increasingly viewed on the basis of consumption. Consequently, decision-makers are now moving away from the confines of rigid capital budgeting processes, which have traditionally compared IS with non-IS-related investments. With this in mind, the authors seek to dissect investment appraisal from the broader capital budgeting process to allow a deeper understanding of the mechanics involved with IS justification. This analysis presents conflicting perspectives surrounding the scope and sensitivity of traditional appraisal methods. In contributing to this debate, the authors present taxonomies of IS benefit types and associated natures, and discuss the resulting implications of using traditional appraisal techniques during the IS planning and decision-making process. A frame of reference that can be used to navigate through the variety of appraisal methods available to decision-makers is presented and discussed. Taxonomies of appraisal techniques that are classified by their respective characteristics are also presented. Perspectives surrounding the degree of involvement that financial appraisal should play during decision making and the limitations surrounding investment appraisal techniques are identifie
Comparison of the chromosome banding patterns in three species of social voles (Microtus irani karamani, M. schidlovskii, M. anatolicus) from Turkey
No full textThe karyotypes of three species of social voles recently discovered in Turkey (Microtus irani karamani, M. schidlovskii, andM. anatolicus) were investigated. All specimens examined revealed similar karyotypes comprising 60 chromosomes in the diploid complement. All autosomes and the X chromosome were acrocentric. The subtelocentric Y chromosome was recorded in M. anatolicusbut it was acrocentric in the other species. Dark C-bands were observed in centromeric/pericentromeric areas of all the acrocentric autosomes. The X chromosome had a centromeric C-positive area and the Y chromosome was completely heterochromatic in all specimens examined. AgNORs were recorded in the pericentromeric region of seven autosome pairs in M. irani karamani, ten autosome pairs in M. schidlovskii, and eight autosome pairs of M. anatolicus. Differences in the NOR distribution between the species were quantified in a neighbor-joining tree. The individuals of M. anatolicus appeared as the basal branch in relation to the derived sister group of M. schidlovskii and M. irani karamani
