A study of the relative proportions of coloured retinal oil droplets in the five Canadian grebe species and the American Coot was undertaken to evaluate the possibility of an ecological rationale to the pattern of variation in these proportions among the species. Statistical analysis suggests that there may be significant differences in these proportions among the six species studied, and that some species show significant heterogeneity among the nine sectors into which the retinas were divided. There was no significant association of oil droplet proportions in either Western or Red-necked grebes with two different lake types. Significantly greater mean total droplet densities were found in the Pied-billed Grebe and the American Coot than the other four grebes; the lowest droplet densities were shown by Western and Eared grebes. The finding of significant within-retina (among-sector) variation, and high levels of individual variation in some species throws into question reported values for other species where single samples have been taken from one or a few individuals.

Introduction: There are many reports of endophthalmitis following Anti- VEG F use in developed countries and from India, but there are none from Nepal yet. Therefore, the aim of this study was to report the prevalence and management of acute endophthalmitis after intravitreal injection of bevacizumab.Methods: This is a clinical, retrospective, non-comparative study, performed in Tilganga Institute of Ophthalmology, Kathmandu, Nepal from Jan 2015 till Dec 2016. All consecutive cases of intravitreal 1.25 mg of bevacizumab injections during the study period were collected from Bevacizumab registry of the operation theatre. A total number of endophthalmitis, following intravitreal bevacizumab injections were collected from Endophthalmitis registry. The statistical analysis was carried out by SPSS for percentage calculation and its 95% Confidence Interval (CI) calculation.Results: There were 4182 injections performed during the study period for various retinal conditions. Two eyes of two patients with acute postoperative endophthalmitis were identified in the first week following intravitreal injections of 1.25 mg bevacizumab among a total of 4128 injections with a prevalence of 0.048% (95% CI: 0.00 to 0.12.).Conclusions: The prevalence of acute endophthalmitis following intravitreal Bevacizumab in our retrospective series was 0.048% and was comparable with the other studies conducted elsewhere. Acute post-injection endophthalmitis following intravitreal bevacizumab can result in severe loss of vision. Therefore prompt recognition and treatment are important part of its management in such patients.

SummarySephadex gel filtration of human plasma gave results suggesting the presence of two proactivators of plasminogen, termed proactivators A and B.Activity resembling that of proactivator A was found in rabbit plasma, but not in guinea pig plasma.Plasminogen activators produced by the interaction of proactivator A of human plasma with streptokinase had no caseinolytic or TAMe esterolytic effect.Proactivator A can be separated in a form apparently free from plasminogen, as shown by the heated fibrin plate test and by immunological analysis. On the other hand, proactivator B concentrates prepared so far are contamined with plasminogen.Human proactivators appear to be far more susceptible to streptokinase than are rabbit proactivators.Inhibitors of the fibrinolysin system were observed in the plasmas of all 3 species. These inhibitors are not present in the euglobulin fraction of plasma. Sephadex fractionation of euglobulin fractions results in proactivator preparations that do not contain inhibitors.

This is the first comparative article to investigate commonalities in Ukrainian and Irish history, identity, and politics. The article analyzes the broader Ukrainian and Irish experience with Russia/Soviet Union in the first and Britain in the second instance, as well as the regional similarities in conflicts in the Donbas region of Eastern Ukraine and the six of the nine counties of Ulster that are Northern Ireland. The similarity in the Ukrainian and Irish experiences of treatment under Russian/Soviet and British rule is starker when we take into account the large differences in the sizes of their territories, populations, and economies. The five factors that are used for this comparative study include post-colonialism and the “Other,” religion, history and memory politics, language and identities, and attitudes toward Europe.

The article presents a contemporary view of the study of piyyut, demonstrating that Jewish poetry of late antiquity (in Hebrew and Aramaic) was closely related to Christian liturgical poetry (both Syriac and Greek) and Samaritan liturgy. These relations were expressed primarily by common poetic and prosodic characteristics, derived on the one hand from ancient Semitic poetry (mainly biblical poetry), and on the other from innovations of the period. The significant connections of content between the different genres of poetry reveal the importance of comparative study. Thus the poetry composed in late antiquity provides additional evidence for the lively cultural dialogue that took place at that time.

Abstract This paper explores intra-individual variation as a manifestation of language-internal multilingualism in the Central-Bavarian Austrian context. Based on speech data from children and adults in different contexts, we discuss different methods of measuring and analyzing inter-situational variation along the dialect and standard language spectrum. By contrasting measures of dialectality, on the one hand, and proportions of turns in dialect, standard language or intermediate/mixed forms on the other, we gain complementary insights not only into the individual dialect-standard repertoires but also into the consequences of different methodological choices. The results indicate that intra-individual variation is ubiquitous in adults and children and that individual repertoires need to be taken into account from the beginning of the language acquisition process. We suggest that while intra-individual variation can be attested through the use of various methods, the revealed level of granularity and the conclusions that can be drawn as to the individual repertoires on the dialect-standard spectrum largely depend on the measures used and their inherent assumptions and intrinsically necessary categorizations.

Neurofuzzy Systems

Systems of distributed generation have shown to be a remarkable alternative to a rational use of energy. Nevertheless, the proper functioning of them still manifests a range of challenges, including both the adequate energy dispatch depending on the variability of consumption and the interaction between generators. This paper describes the implementation of an adaptive neurofuzzy system for voltage control, regarding the changes observed in the consumption within the distribution system. The proposed design employs two neurofuzzy systems, one for the plant dynamics identification and the other for control purposes. This focus optimizes the controller using the model achieved through the identification of the plant, whose changes are produced by charge variation; consequently, this process is adaptively performed. The results show the performance of the adaptive neurofuzzy system via statistical analysis.

Purpose The purpose of this paper is to describe and analyze the rules on the formation of contracts under Korean law and the Contracts for the International Sale of Goods (CISG) in a comparative way and introduce the relevant proposed rules under the Amendment Draft of the Korean Civil Code (KCC). In addition, it attempts to compare and evaluate them in light of the discipline of comparative law. Design/methodology/approach In order to achieve the purposes of the study, it executes a comparative study of the rules as to the formation of contracts of the CISG, Korean law and the Amendment Draft of the KCC. The basic question for this comparative study is placed on whether a solution from one jurisdiction is more logical than the others and to what extent each jurisdiction has responded to protect the reasonable expectations of the parties in the rules as to the formation of contracts. Findings The comparative study finds that most of the rules under the CISG are quite plausible and logical and they are more or less well reflected in the proposals advanced by the KCC amendment committee. On the other hand, the other rules under the CISG which have brought criticisms in terms of their complexity and inconsistent case law invite us their revision or consistent interpretation. The drawbacks of the CISG have also been well responded in the Amendment Draft of the KCC. Nevertheless, it is quite unfortunate that the Amendment Draft of the KCC still has a rule that regards any purported performance with non-material alteration of the terms of an offer as an acceptance. Originality/value This study may provide legal and practical advice to both the seller and the buyer when they enter into a contract for international sales of goods. In addition, it may render us an insight into newly developed or developing rules in this area and show us how they interact with each other. Furthermore, it may be particularly useful in Korea where there is an ongoing discussion for revision of the KCC.

Nanoparticles of Ag with different sizes and structures were obtained and studied. Two methods for reductions of Ag ions were employed, chemical reduction by sodium borohydride and ethylene glycol. Cuboctahedral and icosahedral structures were obtained. Molecular simulations were carried out in order to evaluate the reactivity of both structures. On the other hand, the electrochemical activity and antibacterial effect (E. coli) of the cuboctahedral and icosahedral structures were measured experimentally. The results obtained by molecular simulation, cyclic voltammetry, and antibacterial effect were compared and discussed in this work.
