Roberto Massimo Lawley (1818–1881) was a non-academic naturalist who made a major contribution to the Tuscan scientific community of his time. He was involved in the foundation of two societies (Società Italiana di Malacologia, 1874–1899; Società Toscana di Scienze Naturali, 1874–today) and a publishing house (Biblioteca Malacologica Italiana). He first devoted himself to malacology, but Neogene fossil fishes became his main interest. Over the years, he gathered a huge private collection of fossils and produced 18 scientific papers, dealing mainly with fossil sharks. Subsequent revisers criticized his approach to fossil taxa: their observations were generally sound, but they failed to fully recognize Lawley's scientific merits. His scientific papers, new taxa established by him and eponymys are given in the Appendix.

The bibliography brings together more than 250 scientific papers and books written by Alwyne (Wyn) Wheeler over fifty years, from 1955–2006. This chronological list shows that from the beginning his research followed three themes: taxonomy of historically important fish collections; identification and distribution of the British and European fish fauna ; the status of British fishes in a changing environment. Until the mid-point in Wyn's career he published regularly on the identification of fish remains in archaeological sites in Britain and Europe. Wyn also wrote under an alias, Allan Cooper, and these have been listed separately. The bibliography concludes with a selection of the regular columns he contributed to angling magazines.

География это мировоззренческая наука. Сложившаяся за десятилетия структура курса обучения географии в российской средней школе знакома каждому из нас и состоит из четырёх этапов. В университете система обучения будущих учителей географии состоит из тех же самых этапов, однако, это не просто углублённое повторение школьной программы, это совершенно новый, более высокий уровень географического образования. Как на школьном, так и на университетском уровнях изменения происходят в масштабе тем и разделов отдельных этапов, но этапы остаются неизменными. Межэтапный уровень является предельным, его осознание не попадает в область рефлексии педагогов и методистов. Отсутствуют и научные труды по его анализу. В качестве метода исследования выступает диалектика, законы которой срабатывают в виде мировоззренческих формул. В школьном географическом образовании проблема формирования восприятия не проявляется чётко и поэтому не осознаётся. Проблемы начинают проявляться на межэтапном уровне. Мировоззренческая формула дихотомии перестала работать в виде противопоставления отраслевая география районная география, взаимодействие в этой бинарной оппозиции строилось по принципу отраслевой анализ региональный синтез. В разделах районной географии исчезли механизмы (энергопроизводственные циклы) и формы синтеза (природнотерриториальные и территориальнопроизводственные комплексы). Произошла утрата целесообразности изучения районной географии. Новых форм синтеза в постсоветское время на вооружение российской школьной и университетской географией принято не было. В университетском курсе, который был направлен на осознание диалектических знаний школьного курса и развитие их, невозможно провести рефлексию, так как основы географических знаний у абитуриентов бесформенные. Владение мировоззренческими формулами это вопрос отражения географической реальности. В переходе с уровня на уровень возрастает самостоятельность географического мышления и удаление от стереотипов, возрастает эвристический потенциал за счёт сочетания формул, которое даёт вариативность отражения географической реальности. Geography is a worldview science. The structure of the geography course in the Russian secondary school, which has developed over the decades, is familiar to each of us and consists of four stages. At the University, the system of teaching future teachers of geography consists of the same stages, however, it is not just an indepth repetition of the school curriculum, it is a completely new, higher level of geographical education. At both the school and University levels, changes occur in the scale of topics and sections of individual stages, but the stages remain the same. The interstage level is the limit, its awareness does not fall into the field of reflection of teachers and methodologists. There are no scientific papers on its analysis. The method of research is dialectics, the laws of which work in the form of worldview formulas. In school geographic education, the problem of perception formation is not clearly manifested and therefore is not realized. Problems begin to emerge at the interstage level. The worldview formula of dichotomy ceased to work in the form of the opposition sectoral geography regional geography, the interaction in this binary opposition was based on the principle of sectoral analysis regional synthesis. Mechanisms (energy production cycles) and forms of synthesis (naturalterritorial and territorialproduction complexes) have disappeared in the sections of the district geography. There was a loss of expediency of studying of regional geography. New forms of synthesis in the postSoviet period were not adopted by the Russian school and University geography. In the University course, which was aimed at understanding the dialectical knowledge of the school course and their development, it is impossible to reflect, as the basis of geographical knowledge of students formless. The possession of ideological formulas is the question of geographic reality. In the transition from level to level increases the independence of geographical thinking and the distance from stereotypes, heuristic potential increases due to the combination of formulas, which gives variability of reflection of geographical reality.

Parallel tiered and dynamic models of the fuzzy inference in expert-diagnostic software systems are considered, which knowledge bases are based on fuzzy rules. Tiered parallel and dynamic fuzzy inference procedures are developed that allow speed up of computations in the software system for evaluating the quality of scientific papers. Evaluations of the effectiveness of parallel tiered and dynamic schemes of computations are constructed with complex dependency graph between blocks of fuzzy Takagi – Sugeno rules. Comparative characteristic of the efficacy of parallel-stacked and dynamic models is carried out.

The article analyzes the influence of chemical composition of hythane (a mixture of natural gas with hydrogen) on pressure in an engine combustion chamber. A review of the literature has showed the relevance of using hythane in transport energy industry, and also revealed a number of scientific papers devoted to studying the effect of hythane on environmental and traction-dynamic characteristics of the engine. We have studied a single-cylinder spark-ignited internal combustion engine. In the experiments, the varying factors are: engine speed (600 and 900 min-1), excess air ratio and hydrogen concentration in natural gas which are 29, 47 and 58% (volume).The article shows that at idling engine speed maximum pressure in combustion chamber depends on excess air ratio and proportion hydrogen in the air-fuel mixture – the poorer air-fuel mixture and greater addition of hydrogen is, the more intense pressure increases. The positive effect of hydrogen on pressure is explained by the fact that addition of hydrogen contributes to increase in heat of combustion fuel and rate propagation of the flame. As a result, during combustion, more heat is released, and the fuel itself burns in a smaller volume. Thus, the addition of hydrogen can ensure stable combustion of a lean air-fuel mixture without loss of engine power. Moreover, the article shows that, despite the change in engine speed, addition of hydrogen, excess air ratio, type of fuel (natural gas and gasoline), there is a power-law dependence of the maximum pressure in engine cylinder on combustion chamber volume. Processing and analysis of the results of the foreign and domestic researchers have showed that patterns we discovered are applicable to engines of different designs, operating at different speeds and using different hydrocarbon fuels. The results research presented allow us to reduce the time and material costs when creating new power plants using hythane and meeting modern requirements for power, economy and toxicity.

According to the dominant view, the quality of individual scientific papers can be evaluated by the standard of the journal in which they are published. This paper attempts to demonstrate the limits of this view in the field of economics. According to our main findings, a publication frequently serves as a signal of high professional standards rather than as a source of information; referees and editors frequently reject good papers and accept bad ones; citation indices only partially balance the distortions deriving from the selection process; there are essential “entry costs” to the publication process. Moreover, financial interests of publishers may contradict scientific interests. As long as leading economists do not give voice to their dissatisfaction, there is no hope for any reform of the selection process.
