Two Upper Triassic sphinctozoan sponges of the family Sebargasiidae were recovered from silicified residues collected in Hells Canyon, Oregon. These sponges areAmblysiphonellacf.A. steinmanni(Haas), known from the Tethys region, andColospongia whalenin. sp., an endemic species. The latter sponge was placed in the superfamily Porata by Seilacher (1962). The presence of well-preserved cribrate plates in this sponge, in addition to pores of the chamber walls, is a unique condition never before reported in any porate sphinctozoans. Aporate counterparts known primarily from the Triassic Alps have similar cribrate plates but lack the pores in the chamber walls. The sponges from Hells Canyon are associated with abundant bivalves and corals of marked Tethyan affinities and come from a displaced terrane known as the Wallowa Terrane. It was a tropical island arc, suspected to have paleogeographic relationships with Wrangellia; however, these sponges have not yet been found in any other Cordilleran terrane.

Introduction. To date there is a lack of studies dedicated to the objectification of the palpation data obtained by a specialist during the osteopathic examination. The issue of the evidence of the results of osteopathic correction still remains important. Search for instrumental methods allowing to register and to measure various palpation phenomena and manifestations of somatic dysfunctions is very relevant for the development of osteopathy as a science. It is also very important to find objective characteristics of these methods.Goal of research — to study viscoelastic characteristics of the soft tissues of the lower legs by palpation and instrumental methods before and after osteopathic correction.Materials and methods. 22 volunteers (12 women and 10 men) aged 18–23 years without complaints of the musculoskeletal system were examined. Osteopathic diagnostics and measurement of the viscoelastic properties of muscles were carried out by the method of vibration viscoelastometry before and after osteopathic correction.Results. Correlation analysis by Spearman showed that the subjective assessment of an osteopath positively correlated with both elasticity (r=0,43, p<0,05) and viscosity of soft issues (r=0,29, p<0,05). For the gastrocnemius muscle, this pattern was even more pronounced — for elasticity r=0,51, p<0,05, for viscosity =0,34, p<0,05. After osteopathic correction no changes in the elasticity of the soft tissues were observed. The viscosity of the tissues reduced, but in the projection of the gastrocnemius muscle, these changes were not statistically significant (p=0,12), whereas in the projection of the soleus muscle statistically significant changes (p=0,034) were observed.Conclusion. Changes in the viscoelastic properties of tissues demonstrated that the effects of osteopathic correction with the use of myofascial mobilization techniques, articulation mobilization techniques, and lymphatic drainage techniques were not obvious. The elasticity of soft tissues of the lower legs did not change, while the viscosity decreased, especially in the projection of the soleus muscles. This effect of the osteopathic correction can be associated with the effect of thixotropy — the transformation of gel-like intercellular substance into sol. Thus, the research showed that vibration viscoelastometry can be used for the objectifi cation of the condition of soft tissues and of the effects of osteopathic correction.

Tax Regulation

Subject. Under rapid changes in the external economic environment, new forms and methods of State regulation of oil and gas industries, especially, improving the taxation and tax regulation instruments become relevant. Objectives. The study aims to provide an original interpretation of methods of improving the tax administration of major taxpayers in the oil and gas sector applied at the present stage. Methods. I employ normative and holistic approaches to examine taxation efficiency in the oil and gas sector, general scientific and special methods of scientific cognition, i.e. retrospective, system analysis, observation, classification, instrumental methods of grouping, sampling, comparison and synthesis, as well as evolutionary and dynamic analysis. Results. I consider basic problems and solutions in the sphere of tax administration of major taxpayers of Russian oil and gas industries. The paper offers a package of measures and recommendations aimed at improving the efficiency of tax regulation, underpins the applied approach to tax administration of organizations operating in the oil and gas sector. Conclusions and Relevance. Our country needs a comprehensive program for tax administration of the entire technological cycle: from upstream operations to full-scale import substitution of consumer goods.

Taxonomic Key

Hornstedtia microcheila Ridl. (Zingiberaceae; Alpinioidieae; Alpinieae) is a poorly-known endemic species in the Philippines. It has not been collected again since its description in 1909. In 2017, however, the species was rediscovered in the Mt. Mandalagan Range, Patag, Silay City, Negros Occidental, after a lapse of over a century. A new, amended and extended description of H. microcheila based on this new collection is presented herein. Typification, colour photographs, distribution data, ecological details as well as a taxonomic key to the different Hornstedtia species in the Philippines are also provided.

The Taal Volcano Protected Landscape (TVPL) encompasses a prehistoric volcano caldera that caters to many documented endemic species. Although regarded as a unique area with the potential to house a diverse ecological community, biodiversity research in TVPL is still found wanting. The present paper aims to provide baseline information and increase research interests on the herpetofaunal diversity of TVPL, in light of its many undocumented terrestrial faunal species. Twelve study sites within the municipalities of Tanauan, Mataasnakahoy, and Balete were visited during survey trips from May to November 2015. A combination of transect and opportunistic sampling techniques were utilized, with morphometric data and sexual maturity recorded for each specimen collected. This preliminary survey provided 24 newly documented species of amphibians and reptiles occurring within TVPL. A total 10 frog species (from families Bufonidae, Ceratobatrachidae, Microhylidae, Dicroglossidae, Ranidae, and Rhacophoridae) and 14 reptile species (from families Agamidae, Gekkonidae, Scincidae, Varanidae, Acrochordidae, Colubridae, Elapidae, and Tryonychidae) were documented. Of the reptiles recorded, 3 are endemic species and widespread throughout the Philippines: Gekko mindorensis, Hydrosaurus pustulatus, and Draco spilopterus. Also recorded were the Philippine endemic frogs Kaloula picta and Limnonectes woodworthi along with the Luzon endemics Platymantis mimulus and Varanus marmoratus. The species-effort curve of amphibians showed a distinct plateau whereas the species-effort curve of reptiles has shown an increasing trend suggesting that additional sampling efforts should be done in the area to further increase knowledge of the TVPL herpetofaunal diversity.
