Cruise Report ALKOR 438 [AL438] - Foraminiferal biomonitoring in the North Sea, May 29 - May 31, 2014, Kiel (Germany) - Kiel (Germany)
The aim of R/V Alkor cruise AL438 was to investigate the assemblage composition,
population density and distribution of Recent benthic foraminifera in the Elbe
estuary and southern North Sea. We focused on an assessment of the present state of
the ecosystems and a comparison with data from former decades. Our work resumed
investigations of the Geologisch-Paläontologisches Institut of Kiel University and the
Federal Hydrographic Office from 1960s till the 1980s, as well as topical studies to the
west of Helgoland. We revisited the same stations and took sediment samples with
historical and modern grab samplers, box corer, Minicorer and a gravity corer. These
samples were accomplished with samples from new stations in order to describe the
relationships of foraminiferal faunas living in the Helgoland mud area with those
inhabiting the surrounding sands. The sampling was accompanied with hydrographical
measurements and water sampling to document relevant environmental parameters.
The foraminiferal sampling was carried out for the first time following of the
FOraminiferal BIoMOnitoring group (FOBIMO) recommendations as much as possible,
in order to test the practicability of the guidelines. In total, 109 deployments at 37
stations were successfully accomplished
Применение моделей смешанного обучения в преподавании физической культуры в школе как условие трансформации системы образования
The strategic direction of the modern education system is digital transformation.
The procedure for the use of electronic educational resources is reflected in the regulatory
documents, as well as the concept of teaching the subject “Physical Education”. The
above necessitates the justification of the methodology of teaching physical education in
a general education organization, with the implementation of the blended learning model,
taking into account the optimal combination of the “strengths” of traditional education
(practice-oriented
format) using digital resources and platforms for mastering theoretical
material, control, self-analysis
of the acquired knowledge in the process of studying. In
the course of the study, a work program for basic general education (grades 5–9) was
developed using remote information technologies in the blended learning mode. In the
educational practice of the subject “Physical Education”, the models of blended learning
“flipped class” and “station rotation” are introduced. The results of the experimental work
showed positive dynamics and the possibility of implementing blended learning in the
process of the lesson “Physical Education”Стратегическим направлением современной системы образования
является цифровая трансформация. Порядок применения электронно-образовательных
ресурсов отражен в нормативных документах, а также концепции преподавания
учебного предмета «Физическая культура», что обусловливает необходимость
обоснования методики преподавания физической культуры в общеобразовательной
организации с учётом реализации модели смешанного обучения при оптимальном
сочетании «сильных» сторон традиционного обучения (практико-ориентированный
формат) с применением цифровых ресурсов и платформ для освоения теоретического
материала, контроля, самоанализа полученных знаний в процессе обучения. В ходе
исследования подготовлена рабочая программа основного общего образования (5–9
классы) с использованием информационных технологий в режиме смешанного
обучения. В образовательную практику предмета «Физическая культуры» внедрены
модели смешанного обучения «перевёрнутый класс» и «ротация станций». Результаты
экспериментальной работы показали положительную динамику и возможность
реализации смешанного обучения на уроках по физической культур
Multiyear data on benthic foraminifera in a glaciated fjord of Svalbard
Glaciers in the fjords of Svalbard have been receding over last decades. Tempelfjorden, a typical glaciated fjord in West Spitsbergen (78°24′06″ N, 17°02′30″ E), has been sampled in summer 1995 and 2001–2007 for modern benthic foraminifera. We have normalized the abundances and unified the taxonomy of all these published and unpublished data sets and then compiled the record of foraminiferal assemblages changing over years into a comprehensive database. The record includes data on living and dead abundances of benthic foraminiferal species in the surface sediments (0–2 cm) and downcore abundances of living foraminifera (only for 2004). This database portrays benthic foraminifera, this key group of microfossils, in a gradually changing Arctic environment
Application of Multi-Criteria Decision Analysis for Choice Geokhods Cutting Head
The article deals with the choice of cutterheads for Geokhod in the early development stages. Early development stages are characterized by the lack of quantitative characteristics, such as cutting forces, weight, feed forces, etc. In this case, the choice is made on the accordance of the cutterheads with the requirements for them. Under such conditions were determined the most appropriate method of multi-criteria analysis for the choice of the cutterheads – “ELECTRE III”. The results of the use of this method are established the most fully meet the requirements cutter heads: a rotary, drum, and head with fixed heads
The Helgoland Experiment - assessing the influence of methodologies on Recent benthic foraminiferal assemblage composition
Most recent benthic foraminiferal studies focus on species inventory and distribution and ecology. An integration of results from different studies is often hampered by the application of different methods. The influence of different sample treatments and analyses on the accuracy of faunal data is the subject of the present study. We compare preservation, staining, and preparation techniques to constrain the internal data variability as inferred by different methodologies. Variations produced by different persons analysing the same foraminiferal assemblage and consequences for the accuracy of foraminiferal data are addressed.
We retrieved a large surface sediment sample from the southeastern North Sea near Helgoland. Twelve replicate subsamples were taken and preserved with ethanol, ethanol - rose Bengal solution, or formaldehyde. Samples were then processed with standard methods. Some samples were stained after processing with an aqueous rose Bengal solution, or the foraminifera were concentrated by floatation. Coloration of specimens that were living at the time of sampling was different between samples where rose Bengal was added together with the ethanol and samples, which were stained after washing. In the latter case, only the last two or three chambers were impregnated. The sample preserved with formaldehyde showed dissolution features affecting both arenaceous and calcareous species. In particular, the outer shell layer of miliolids was corroded, calcareous cement of agglutinated tests was reduced, and pores of rotalids were enlarged. The population density reflecting the number of recognised, stained specimens was highly variable among different preservation, picking modes, and examinators. The accuracy of picking was in the range of ±4 % (1-sigma), while the reproducibility ranged from -44 to +26 % between different examinators, which also concerns the proportions of dominant species. There was no significant difference between wet and dry picking within the 95 % confidence limits, but samples that were stained later or concentrated by floatation generally yielded a lower number of specimens. Arenaceous species and miliolids were underrepresented in samples that were stained after washing and in the floatation concentrate while Stainforthia fusiformis was seemingly better recognised therein. More data and parallel investigations involving a larger number of specialists are needed to achieve a better comparability of faunal census data
Company’s management in case of emergency and ecological disaster
Emergency is the violation of normal living conditions and activities of people at the facility and a certain territory that arose as a result of an accident, catastrophe, natural disaster, epidemic, as well as the use of modern weapons by the enemy, which led to human casualties, damage to health and the environment, material losses. This article discusses the management of the work of enterprises and organizations in emergency, problems associated with natural emergencies (natural disasters). Emergency management involves the creation of a system consisting of a number of subsystems. The authors analyse the possible ways of solution the problem of the company’s management in emergency
TRENDS OF THE DEVELOPMENT OF HIGHER PHARMACEUTICAL EDUCATION
The dynamic development of the pharmaceutical industry in the Russian Federation is closely connected with training of qualified personnel, which in turn requires modernization of the education programs of higher professional education. Comparative analysis of the field, objects and kinds of professional activity, professional tasks of the pharmacist presented in the current Federal state educational standard (FSES HPE 3) and the new FSES HE 3+ in the specialty «pharmacy» allows to identify the main patterns and trends in the development of the Russian pharmaceutical education. Educational programs developed and implemented by institutions of higher vocational education must meet the requirements of employers for graduates with regard to the transfer of the domestic pharmaceutical industry to international standards
Intertidal foraminiferal fauna and the distribution of Elphidiidae at Chupa Inlet, western White Sea
The bright colouration of the cytoplasm in intertidal rotaliid foraminifera and their particle-gathering activity reliably reveals live specimens in fresh samples, without any fixatives or dyes applied. Using this approach, we demonstrate that live representatives of three rotaliid species, all belonging to the genus Elphidium, were common on intertidal mud and sand beaches. Two species, E. excavatum clavatum and E. albiumbilicatum, lived close to freshwater outflows, whereas E. williamsoni occupied beaches bathed by waters with normal salinity (surface 26–27‰ in the western White Sea). A least 13 species were found alive in the intertidal zone. Among non-calcareous foraminifera, Miliammina fusca, Ammotium cassis and Ovammina opaca were the most numerous
Particularities of the sustainable energy technologies and labour market in Russia
The energy sector is now experiencing a renaissance thanks to new opportunities offered by innovative technologies that are filling the market, for example in the field of storage and management of electrical energy. For the controlled development of distributed generation, maintaining the stability of the energy system while maintaining the price advantages of small generation, the speed of commissioning new power capacities and the scalability of the solutions used, a new subject of relations in the electricity market is proposed - an active energy complex. This is an energy system that is electrically connected within the general boundaries of the balance sheet membership, which includes energy receiving, generating, accumulating (if any), electric grid energy equipment and a control system for this energy system as a single complex in order to meet energy needs. There is a contradiction between the development of the labour market and the achievement of environmental well-being. On one hand, environmental pollution, depletion of natural capital has a negative impact on the state of the labour market, employment of the population, and on the other hand - activities to improve the environment, eliminate the accumulated environmental damage, the development of a market for environmental works, goods and services promote the expansion of employment, not only green, but general employment
