Generalne Gubernatorstwo w raportach Służby Bezpieczeństwa Reichsführera SS
Authors: Przegiętka Marcin
Published: February 2020

Służba Bezpieczeństwa Reichsführera SS (SD) była organizacją wywiadowczą SS i NSDAP w III Rzeszy. Po przejęciu władzy przez NSDAP w Niemczech w 1933, rosły wpływy SD, która rozciągnęła swoją kontrolę na wszystkie najważniejsze stanowiska w aparacie bezpieczeństwa III Rzeszy. Od 1939 r. SD stała się częścią Głównego Urzędu Bezpieczeństwa Rzeszy (Reichssicherheitshauptamt; RSHA). Podlegały jej również grupy operacyjne Policji Bezpieczeństwa i SD, które działały w Polsce po niemieckiej inwazji (1 września 1939 r.). Podczas okupacji (m.in. w Generalnym Gubernatorstwie) SD stanowiła wsparcie dla Gestapo.SD odpowiadała za zbieranie informacji służących badaniu stosunku obywateli III Rzeszy i terytoriów okupowanych do władz Rzeszy, lecz również bieżących wydarzeń politycznych i przebiegu wojny. Opinie społeczeństwa Generalnego Gubernatorstwa (Polaków, Żydów, Ukraińców i Niemców) były nie tylko probierzem aktualnego stosunku ludności wobec władz Rzeszy, lecz również pozwalały na ocenę efektywności oficjalnej propagandy.

Pemeliharaan tanaman tomat membutuhkan perhatian khusus karena jika tanaman ini tidak mendapatkan kondisi atau keadaan yang baik maka tanaman ini tidak dapat tumbuh dengan baik, misalnya kondisi kelembaban tanah yang tidak sesuai maka tanaman akan lambat berbuah dan bahkan tidak berbuah sama sekali. Selain itu suhu ruangan yang ideal dan pencahayaan yang baik juga sangat diperlukan. Sangat sulit memenuhi kebutuhan tersebut jika hanya melakukan pemeliharaan secara manual dengan tenaga manusia seperti menyiram secara manual. Maka dari itu diperlukan sebuah sistem yang dapat mengendalikan dan memantau kelembaban tanah, suhu udara dan cahaya untuk pemeliharaan tanaman tomat. Dengan adanya sistem ini diharapkan dapat mengurangi resiko kegagalan dalam pemeliharaan tanaman tomat dan diharapkan dapat mengontrol dan memantau keadaan tanaman tomat itu sendiri, serta dapat meringankan pekerjaan manusia dalam proses pemeliharaan dikarenakan proses yang dilakukan secara otomatis. Sistem ini mengendalikan semua perangkat secara otomatis dikarenakan menggunakan sensor untuk membaca nilai yang ada pada sekitar, sensor kelembaban tanah berfungsi untuk membaca nilai kelembaban tanah dan sekaligus untuk mengatur kendali dari pompa air untuk melakukan penyiraman, sensor DHT22 berfungsi untuk membaca nilai suhu ruangan untuk mengatur pengoperasian fan dalam menstabilkan suhu ruangan agar tetap stabil di bawah 29oC yang sudah disesuaikan dengan kebutuhan tanaman suhu tomat, dan sensor LDR (Light Dependent Resistance) untuk membaca pancaran sinar matahari untuk mengatur saklar yang terhubung dengan lampu agar lampu dapat aktif dan tidak aktif secara otomatis hal ini dikarenakan tanaman tomat memerlukan pancaran sinar cahaya atau sinar matahari lebih dari 12 jam per harinya. Sistem ini dapat berfungsi sebagai pengendali dan pemantau untuk pemeliharaan tanaman tomat berdasarkan masukan dari masing-masing sensor.

The purpose of writing this research is to find out how the implementation of social responsibility press theory in the coverage of Central TVRI. In this study, the author only focuses on the forms of implementation of the theory of social  responsibility press which are carried out in the news. Data collection techniques used are observation, interview and documentation. The theory used in this study is the Social Responsibility Theory of the Press, and the concepts used are mass media, television, and TVRI as public service partners. From the findings, it can be concluded that there are a number of indicators that are the main principles of social responsibility that TVRI has implemented, namely accepting and fulfilling obligations to the community, providing space for the community to convey a viewpoint as a form of community control to build a better TVRI, avoid reporting which can divide unity and unity, but TVRI has so far not been able to manage its institutions independently without any political intervention because the existing regulations limit the space for TVRI. In the news that hit the public and the government TVRI could not present information that was neutral because of government factors as a form of interpretation of the country so that TVRI took a position as a media that presented news that did not become a control of power.

Implementation of Coulomb blockade transport on a semiconductor device simulator and its application to tunnel-FET-based quantum dot devices
Authors: Iizuka Shota , Asai Hidehiro , Hattori Junichi , Fukuda Koichi , Mori Takahiro
Published: February 2020

The quantum transport model describing the Coulomb blockade observed in semiconductor quantum dot devices is implemented on a semiconductor device simulator. The model considers tunnel path change with varying applied voltage, due to carrier redistribution with changing the voltage, in semiconductor quantum dot devices. We applied the model to simulate characteristics of tunnel-FET-based quantum dot devices. We observed two Coulomb oscillation peaks in OFF-state voltage region in gate-voltage-drain-current curves. Also, a so-called Coulomb diamond, which is shown in a mapping of current-voltage characteristics of quantum dot devices, is successfully observed. Finally, we discuss the tunnel path depending on applied voltages, which implies that the simulation with the model successfully considers carrier redistribution in semiconductor quantum dot devices.

Published: February 2020

The paper presents the results of our comprehensive studies of the saline rivers of the arid Prieltonie region based on hydrobiological surveys of plankton and bottom communities. We have compared two tables of the specific structure according to the results of observations at 13 river sites in 2013 and 2018, which included the numbers of hydrobionts of 94 different taxonomic groups of macrozoobenthos, meiobenthos and zooplankton. Using the method of joint inertia analysis, we have revealed a high statistical consistency of the data matrices, due to objective laws of the spatial distribution of aquatic organisms. A randomization test of the Procrustean correlation coefficient showed the statistical significance (p = 0.00026) of the conjugacy of both specific structures in the space of latent variables. At the same time, a certain trend was noted in the changes in the taxonomic composition of communities at individual stations over time under the conditions of dynamic abiotic factors. We have analyzed the dependence of the taxonomic structure of hydrobionts on a set of 30 abiotic environmental factors obtained during hydrobiological and hydrochemical monitoring of the studied river sections. Using canonical correlation analysis and the projection method on latent structures, a set of ordination diagrams was plotted to allow revealing peculiar “ecological niches” for each group of species with a certain set of characteristics of their biotopes. The plankton and bottom communities were shown to correlate quite well with each other, which indicates a close relationship between them, due to both biotic interactions and a mutually agreed response to changes in aquatic factors.

Published: February 2020

The data of floristic studies of 40 spring tracts of the Mangistau, Aktobe, Atyrau and West Kazakhstan regions of the Western Region of the Republic of Kazakhstan are presented. We have found that the studied flora is represented by 252 species, 167 genera and 55 families belonging to Equisetophyta, Pinophyta, and Magnoliophyta divisions. Taxonomic characterization of the flora showing the predominance of the Asteraceae and Poaceae families is provided. The predominance of perennial herbaceous plants in the flora of spring tracts was identified by the system of I. G. Serebryakov’s life forms. The predominance of steppe plants and weeds was revealed. Horological analysis showed the leading set of species with the Eurasian range type. Ecological characteristics highlighted the predominance of xerophytes and mesotrophic plants. 20 protected plant species listed in the Red Data Book of the Russian Federation and the Red Data Book of the Republic of Kazakhstan were identified. Analysis of the distribution of plants in the areas adjacent to the springs identified four grades of occurrence, namely: common species – 7; uncommon species – 17; rare species – 100; and very rare species – 128. The most common species found within the spring tract territories are related to weeds, such as Tripleurospermum perforatum (Merat) M. Lainz, Polygonum aviculare L., Taraxacum officinale Wigg., Lappula squarrosa (Retz.) Dumort., Plantago major L., Arctium lappa L., Xanthium strumarium L., Capsella bursa-pastoris (L.) Medik., Chenopodium album L., Convulvus arvensis L., Poa annua L., Bromus squarrosus L., Elytrigia repens (L.) Nevski. The Jaccard index (Kj) for the analyzed floras in pairwise comparison varies from 0.02 to 0.5, which shows the extreme heterogeneity of the specific composition.
Population Approach to Determination of the Borders and Number of Natural Plague Foci
Authors: Sludsky A. A. , Boiko A. V. , Lyapin M. N. , Tarasov M. A.
Published: February 2020

Population approach to determination of the borders and number of natural plague foci implies the specialists’ acceptance of the concept that the existence of a natural plague focus is always provided by a single population of the main carrier. Motivation for our discussion of such an approach was the data of a long-term study of the Hissar natural plague focus (Tadzhikistan). The area of the focus was only 300 km2 and its functioning was maintained by a single, relatively small population of Microtus carruthersi (Thomas, 1909) – the main carrier of plague. The Hissar mountain range territories adjacent to the focus have been surveyed for plague for more than 20 years, however, no plague agent (Yersinia pestis Lehmann, Neuman 1986) has been found, despite the complete identity of the species composition of rodents and fleas. Many of the known natural plague foci are significantly larger in size than the Hissar focus and inhabited by several populations of the main carrier. For instance, in the East-Caucasian high-mountain focus, covering the area of 23,500 km2 , five groups of common vole populations (the main carrier of plague) are distinguished (Microtus arvalis Pallas, 1778). In the Tuva mountain focus, the plague agent was detected in six populations of the main carrier – the long-tailed souslik (Spermophilus undulates Pallas, 1778). In the territory of the Mojynkumsky desert natural plague focus that occupies 93,000 km2 , 17 populations of the great gerbil (Rhombomus opimus Lichtenstein, 1823) were singled out. Similar data are available for a number of other foci. Revealingly, in different populations of the main carriers, genotype differences were identified, both in rodents and the plague agent, as well as asynchrony in the plague epizooty development. Thus, the plague parasitic coenosis, operating within the boundaries and in the territory of a single population of the main carrier, constitutes an autonomous, standalone natural focus. Therefore, the foci with several populations of the main carrier are, in fact, groups of autonomous foci with a close, similar biocoenotic structure. There are many more natural (autonomous) foci within the natural plague focality zone than is widely assumed.
Population Resilience of Small Mammals. Why it is Important and What it Depends On?
Authors: Shchipanov N. A.
Published: February 2020

Small mammals are an active component of ecosystems that supports energy and matter flows and they are responsible for both construction of and maintaining their habitat. Such activity is vital for human prosperity, as it supports the chemical and physical quality of the environment where the human is adapted as a biological species. The contemporary human activity has resulted in destruction of a number of natural habitats and, as a consequence, in drastic changes in the species abundance. Some species have become so abundant that pose problems for human health, agriculture, and industries. Some formerly common and even pest small mammals, on the contrary, have reduced in distribution and numbers and now fall in the category of vulnerable species. In both cases, ecologically-based management of populations is required to maintain an optimal abundance of various species. Effective ecologically-based management of populations could be based on the basic principles of population ecology. It implies our understanding of both external and internal factors affecting the population abundance. Here, I review some fundamental principles which could be applied to operational management of populations. Also, I focus on some specifics of population reactions which have been elaborated in the Russian ecological school. Based on the well-known principles of supporting the numbers of populations, I propose a classification of species in terms of their ability to provide and change the type of functions in local populations. My classification allows distinguishing three groups of species with predictable resilience of population. Fitted to various environmental instabilities, the species of these groups require different conservation tactics.

The structure of UWAN is problematic as the endeavors of underwater are totally disparate compared to terrestrial networks. A lot of factors which, includes the behavior of the wireless activities in underwater at the time of designing and modeling the original activities of wireless communication in underwater. Additionally, the data or signal transmission and fading losses are exceptionally high in UWAN than air. Thus, separation of communication channels is curiously inflexible to model for all purposes. The acoustic waves are the best disclosures for UWCN contrasted with other wave communication (Electromagnetic or Optical wave). The acoustics communication is demonstrated to be the best of UW in spite of the fact that they are restricted to channel allocation and bandwidth because of thermal_noise. Simultaneously acoustics_sound waves afford the sturdy communication everywhere, territory concerning separation and channel detachment appearing differently in relation to other communication techniques, because of its exceptional property has low attenuation in sound communication in underwater. In this proposal, the various parameters along with the mathematical model for multichannel communication of the acoustic_channel, attributes of acoustics, and various parameters investigated. Additionally, we investigate regulation techniques for acoustic systems that can be utilized in the transmitter and recipient.
