No full textIxobrychiphilus n. gen. Zoobank: BEEDD67E-9954-4954-B469-32B6FE2B4ADE Diagnosis — Female: Small sized syringophilids (total body length 490 – 540). Gnathosoma. Hypostomal apex rounded, without protuberances. Lateral hypostomal teeth absent. Peritremes M-shaped with clearly visible chambers in each branch. Anterior tip of each movable cheliceral digit with 2 teeth. Stylophore rounded posteriorly. Idiosoma. Six pairs of propodonotal setae arranged 2-1-1-1-1. Setae d1 situated closer to d2 than to e2. Agenital series with 3 pairs of setae. Each pseudanal and genital series with 2 pairs of setae. All idiosomal setae smooth and whip-like. Legs. Legs I thicker than II. Antaxial and paraxial members claw pair subequal in size and shape, without basal angle. Apodemes I parallel, not fused to apodemes II. Legs with full complement of setae. Male: Unknown. Type species — Ixobrychiphilus wallacei n. sp. Etymology — The name " Ixobrychiphilus " is taken from the generic name of the host – Ixobrychus, and philus (Gr. phileo – lover of). Differential diagnosis — This new genus is morphologically similar to Niglarobia Kethley, 1970 associated with charadriiform birds. In females of both species, the lateral hypostomal teeth are absent; the apodemes I are parallel and not fused to the apodemes II; the stylophore is without large tip on the posterior margin. This new genus is distinguished by the following features: in females of Ixobrychiphilus, propodonotal setae are arranged 2-1-1- 1-1; legs I are thicker in comparison to legs II; legs I-IV are with full complement of setae, and claws of legs I-IV are without the basal angles. In females of Niglarobia, propodonotal setae are arranged 2-1- 1-2; legs I and II are equal in thickness; leg setae vsII are absent, and claws of legs I-IV are with the basal angles.Published as part of Skoracki, M., Zmudzinski, M. & Solarczyk, P., 2017, Ixobrychiphilus, a new genus of the family Syringophilidae (Acariformes: Prostigmata), pp. 269-273 in Acarologia 57 (2) on page 270, DOI: 10.1051/acarologia/20164155, http://zenodo.org/record/464026

Male. Not found. Type material. Female holotype and three female paratypes from the under-tail covert quill of the purplerumped sunbird Leptocoma zeylonica (Linnaeus) (host no. ZSM 11.1161/V188-9, male); SRI LANKA: Kahatagasdigiliya, 7 March 1911, coll. C.B. Haniel. Mites removed by M. Skoracki and M. Zmudzinski in 2017. Type material depository. All type specimens are deposited in the AMU, except 1 female paratype in the ZSM. Differential diagnosis. The new species, Neoaulonastus sidorchukae sp. nov., is morphologically most similar to Neoaulonastus cinnyris Klimovicova, Smolak, Njoroge & Hromada, 2014 described from Cinnyris mediocris Shelley (Nectariniidae) in Tanzania (Klimovicova et al. 2014). In females of both species, the infracapitulum and the stylophore are apunctate; the movable cheliceral digits are about 90 long; the propodonotal shield is with concave anterior margin, weakly sclerotized, and apunctate; setae vi and si are subequal in length; bases of setae se are situated anterior to the level of setal bases c1; the hysteronotal shield is fused to the pygidial shield; setae h1 and f1 are subequal in length; genital setae are about twice as long as pseudanal setae; all coxal fields are apunctate; and fan-like setae p’ and p” of legs III and IV have six tines. The new species differs from N. cinnyris by following features: in females of N. sidorchukae, each medial branch of peritremes has two chambers; setae c2 and d2 are 90–130 and 140–160 long, respectively; and the genital plate is absent. In females of N. cinnyris, each medial branch of peritremes has three chambers; setae c2 and d2 are 155–190 and 90–115 long, respectively; and the genital plate is present. Etymology. This species is named in honor of the prominent Russian acarologist and paleontologist Dr. Ekaterina (Katya) Sidorchuk (Paleontological Institute of the Russian Academy of Sciences, Moscow), who died in a tragic accident. Remarks. During the study, eight individuals of Leptocoma zeylonica were investigated, two of them were infested with Neoaulonastus sidorchukae sp. nov.

Atypical status of bovine spongiform encephalopathy in Poland: a molecular typing study
No full textThe aim of this study was to analyze molecular features of protease-resistant prion protein (PrPres) in Western blots of BSE cases diagnosed in Poland with respect to a possible atypical status. Confirmed cases were analyzed by Western blotting with several monoclonal antibodies directed at N-terminal and core epitopes of prion protein (PrP). Most cases showed the classical glycoprofile characterized by the dominance of the di- over the monoglycosylated PrPres band, yielding di-/mono- ratios well above 2 and by reactivity with antibodies having their epitopes in bovine PrP region 110-242 (C-type cases). Surprisingly, seven cases of BSE were atypical. Six were classified as L-type based on a slightly lower molecular mass (M-r) of the non- glycosylated band with respect to C-types and a conspicuously low di-/mono- ratio of glycosylated PrPres bands approaching unity. One case was classified as H-type because of a higher M-r of PrPres bands on the blot when compared with C-type cases. A characteristic epitope of H-type PrPres occurred in the 101-110 region of PrP for which only antibody 12B2 had a sufficient affinity. The occurrence of atypical cases only in animals 9 years of age and older raises questions about the mechanisms of prion diseases and the origin of BSE

Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods

Simulation of thermal plant optimization and hydraulic aspects of thermal distribution loops for large campuses
No full textFollowing an introduction, the author describes Texas A&M University and its utilities system. After that, the author presents how to construct simulation models for chilled water and heating hot water distribution systems. The simulation model was used in a $2.3 million Ross Street chilled water pipe replacement project at Texas A&M University. A second project conducted at the University of Texas at San Antonio was used as an example to demonstrate how to identify and design an optimal distribution system by using a simulation model. The author found that the minor losses of these closed loop thermal distribution systems are significantly higher than potable water distribution systems. In the second part of the report, the author presents the latest development of software called the Plant Optimization Program, which can simulate cogeneration plant operation, estimate its operation cost and provide optimized operation suggestions. The author also developed detailed simulation models for a gas turbine and heat recovery steam generator and identified significant potential savings. Finally, the author also used a steam turbine as an example to present a multi-regression method on constructing simulation models by using basic statistics and optimization algorithms. This report presents a survey of the author??s working experience at the Energy Systems Laboratory (ESL) at Texas A&M University during the period of January 2002 through March 2004. The purpose of the above work was to allow the author to become familiar with the practice of engineering. The result is that the author knows how to complete a project from start to finish and understands how both technical and nontechnical aspects of a project need to be considered in order to ensure a quality deliverable and bring a project to successful completion. This report concludes that the objectives of the internship were successfully accomplished and that the requirements for the degree of Degree of Engineering have been satisfied
