Nepenthes is a unique carnivores plant that can be found in Padat Karya forest, Krayan at the North Kalimantan. The existence of these plants can be used as a media of learning so that learning activities become more contextual. The aims of this study are 1) to know the diversity of Nepenthes in Padat Karya forest, 2) to determine the feasibility of learning media in the form of poster developed from the results of the Nepenthes diversity research. This research consisted of two stages. The first was research stage which involved inventory, identification, and diversity index determination of Nepenthes. The second stage was development research i.e developing the results gained from the first stage into poster form. The research and development model employed in this study was the modified-Borg and Gall (2006) model. There were five steps conducted, namely (1) need analysis, (2) planning, (3) develop the preliminary form of product, (4) preliminary field testing, and (5) main product revision. The results showed that the diversity index value of Nepenthes was categorized as ‘medium’. In addition, based on the validation and response obtained, the poster developed was feasible to be utilized as a learning media in senior high school.

The Katav-Ivanovsk transpression zone experienced at least two stages of tectonic deformations, and the sequence of deformations was approximately the same throughout the entire zone — from the Bakal-Satka fault in the south to the Suleimsky fault in the north. Three stages of the formation of parageneses were identified. The parageneses of the first and the second stages were formed in a pure shear environment, and the paragenesis of the third stage — in a simple shear environment. There are stylolites (S1) parallel to bedding, and mineral veins (V1) in the paragenesis of the first stage. Paragenesis of the second stage combines stylolites (S2), mineral veins (V2) and intergranular cleavage (S2). In paragenesis of the third stage were distinguished schistosity (S3), milonites (S3), cataclasites, mica packets (SC-textures), and the rotation structures of porphyroblasts.

Abstract The controls that affect the structure and timing of terminations are still poorly understood. We studied a tufa deposit from the Iberian Peninsula that covers Termination II (T-II) and whose chronology was synchronized to speleothem records. We used the same chronology to synchronize ocean sediments from the North Atlantic to correlate major climate events in a common timescale. We identify two stages within T-II. The first stage started with the increase of boreal summer integrated solar insolation, and during this stage three millennial climate oscillations were recorded. These oscillations resulted from complex ocean–atmosphere interactions in the Nordic seas, caused by the progressive decay of Northern Hemisphere ice-sheets. The second stage commenced after a glacial outburst that caused the collapse of the Thermohaline Circulation, a massive Heinrich event, and the onset of the Bipolar Seesaw Mechanism (BSM) that eventually permitted the completion of T-II. The pace of the millennial oscillations during the first stage of T-II controlled the onset of the second stage, when the termination became a non-reversible and global phenomenon that accelerated the deglaciation. During the last the two terminations, the BSM was triggered by different detailed climate interactions, which suggests the occurrence of different modes of terminations.

The main trends in the ethnic transformation of the post-Soviet space were set long before the collapse of the Soviet Union. The most striking example of this is the process of ethnic transformation in the macroregion, including the territory of the young states of Central Asia (Kazakhstan and the republics of Middle Asia). The aim of the study is to identify the main trends in the transformation of the ethnic space of the Central Asian macroregion over a 120-year interval. For this, a set of ethnic indicators (ethnic mosaic, homogeneity, concentration, etc.) were used, calculated according to the results of censuses and population counts, as well as the methods which have been created in Russian cultural geography. As a part of the study period, two stages were distinguished, characterized by directly opposite trends in the transformation of the ethnic space of the macroregion. The first stage lasted until the end of the 1950s. It was characterized by a decrease in the share of the titular nations of the republics as a result of a significant migration influx of the population from outside the macroregion, which led to an increase in the degree of multi-ethnicity of the territory. Since the 1960s an increase in the share of the titular nations of the republics began, which was a consequence of the demographic explosion of the indigenous population and the migration outflow of non-titular peoples of the republics, and the concentration of titular ethnic groups within their republics increased. The most significant ethnic restructuring throughout the period was experienced by Kazakhstan and the North of Kyrgyzstan. In the second stage the ethnic structure of the population has undergone a radical transformation of all large cities in the macroregion underwent.

Two Stages

The determination of the scope of the fiduciary duty of loyalty, when created by contract, is not a unitary process. It is raised following a multi-factorial enquiry, which considers the nature of the engagement, in a first stage. Here, no single factor is conclusive. It is then, in a separate, second stage, reduced by qualifying contractual terms, which are applied almost strictly logically. This second stage uses the contractual doctrines of interpretation and implication. However, since it is a form of the fiduciary doctrine of authorisation, those contractual doctrines are modified according to fiduciary principles. We argue this follows from the underlying nature of the fiduciary obligation as a way of resolving its internal tensions. While this division has not yet been fully recognised in the cases, the courts have been inching towards it. However, not fully recognising this inevitable division and eliding the two stages has led to defective reasoning and outcomes.

The trends in the official Russian arctic media discourse reflect a sustainable public interest to the issues of the Arctic national development, as well as to the geo-political situation and Russia’s military buildup in the North. The article analyzes the trends in the coverage of Arctic-related issues in the official Russian discourse by the example of “Rossiyskaya Gazeta” — the official print newspaper of RF government. The study covers the period of 2001–2018, which is characterized by topicality of arctic discourse. The dynamics of the discourse can be visibly divided into two stages. The first stage started in 2001 and finished in 2007 with the Russian expedition “Arctic-2007”, which planted the flag of the Russian Federation on the bottom of the Arctic Ocean. The discourse of the stage features low frequency of publications on the topic and neutral emotional text sentiment. The discourse of the second stage (2008–2018) exhibits a noticeably wider topical range of publications on Arctic-related issues, as well as their reactionary and agonic spirit. The analysis resulted in an inference that the publications on Arctic-related problems in the newspaper reflect the official position of RF authorities, and have a specific-reason character.

The article provides the results of the experiments on determination of optimal parameters for obtaining isolated proteins from grains of cultivated and wild pea for use in breeding for quality. The flour of pea varieties Sophia, Rodnik and wild accession k-3370 (Pisum sativum L. ssp. Elatius) were used in the experiment. Isolated pea proteins were obtained based on alkaline extraction and isoelectric precipitation. The experiments were carried out with the use of complete and fractional factorial plans with two levels of factors. Extraction and precipitation of protein were conducted in two stages. One hundred grams of flour were used for extraction. Influence of factors (variety, pH, duration of extraction) on the yield of isolated protein, extraction efficiency, crude protein and fat content in protein isolates was studied. All isolates were characterized by high content of crude protein (90.2-93.1 %). It was determined that increase of pH higher than eight led to enhancement of protein yield and decrease of crude protein content. The results obtained raise the possibility of effective extraction at decreased level of pH that prevents the formation of toxic chemicals. Increase of pH promoted fat accumulation in protein isolate especially at the second stage of extraction. Thus, obtaining protein isolates for evaluation of pea genetic resources should be conducted during a single cycle of extraction and precipitation. The experiments have not revealed significant differences between cultivated and wild pea as to the technology of extraction. The results of the studies are important for evaluation of pea genetic resources according to functional properties of protein isolates.

The paper presents an experimental dynamic analysis of the existing footbridge across the Berounka River in Dobřichovice town, Czech Republic. The experiment was realized in two stages. The main purpose of the first one was the vibration response determination of the footbridge induced by pedestrians. At first, the natural frequencies and mode shapes of its horizontal load-bearing structure were measured and then the footbridge was loaded by different groups of pedestrians. The response was observed and dynamic behaviour of the footbridge was evaluated. In the course of the second stage of the experiment, the dynamic response of the footbridge deck to pedestrian traffic was measured by two different methods using radar interferometry and classical approach realized by piezoelectric accelerometers. Basic objectives of the second stage were to evaluate the fundamental modal characteristics of the footbridge and to verify new approach to dynamic response measurement – radar interferometry realized by two synchronized radars.

Airport is a facility to accommodate arrivals and departures as well as aircraft movements that have the potential to cause noise impacts. This research was conducted to obtain opinions from the public regarding the noise that occurs around Husein Sastranegara Airport, Bandung, Indonesia. In addition, the determination of the airport noise area was also carried out using the Weighted Equivalent Continuous Perceived Noise Level (WECPNL) method. There are 12 measurement points, namely at distances of 100 m, 500 m, and 1500 m in each of the North, East, South, and West directions. Opinions regarding the noise that occurred were obtained from 150 respondents from the community around the airport. The results of the study can be concluded that the highest WECPNL index value is found on the 100 m runway, the WECPNL index value is 76.39, the 500 m distance the WECPNL index value is 62.71, and the 1500 m distance the WECPNL index value is 52.74. The results of the WECPNL index at Husein Sastranegara International Airport Bandung have a level 2 noise area where school buildings and settlements should not be allowed. The results of the interviews show that as many as 54% of respondents feel disturbed by the noise caused by the activities of Husein Sastranegara Airport.
