France in the Process of the Resolution of Conflicts on the African Continent
Authors: Smirnova Olga
Published: July 2019

Introduction. Historically, France has always had an impact on the African continent. Despite the independence of most French colonies in Africa, France managed to maintain its position in the region. The system called “Françafrique” was created. The first element of this system is economic cooperation, namely the fact, that Africa provides an opportunity to use its natural resources. Another important element is the military one. The White paper of France has repeatedly emphasized the strategic importance of Africa for the Fifth Republic. In the 2010s, the situation in the region deteriorated. France’s assistance in overcoming internal crises in Mali, Chad, Libya can be considered an evidence of the increasing role of France in conflict resolution, and that is the thing which is analyzed by the author in this work.

Methods and materials. While writing the article, both official documents of the French government and analytical works of famous French authors were used. Both general scientific methods (analysis, synthesis) and quantitative scientific methods (event analysis and content analysis) are used in the paper.

Analysis. The article is devoted to the activities of France on the African continent in the period from 2011 to 2017. A Special attention is paid to the role of France in the conflict resolution of Africa. In particular, the paper considers France’s support for the adoption of the UN resolution in response to the civil war in Libya in 2011 and military intervention in the country; military operations of the Fifth Republic in the Sahel zone – Serval operation and in the Central African Republic – Sangaris operation, military presence of France in Djibouti. The paper emphasizes the key provisions of the French policy towards the African continent aimed at the preservation of French influence in the region.

Results. In the article, the author comes to the following conclusions: France is not ready to abandon its military ambitions, it continues Barkhane operation, without stopping the fight against terrorism in the Sahel region; despite the competition from other countries (in particular, China and Japan), France’s military presence in Eastern Africa remains the same, France does not intend to leave the base in Djibouti.
New Data on the Chronology and Development of Cattle Breading During the Eneolithic and Early Bronze Age in the Southern Ural Region
Authors: Morgunova Nina , Roslyakova Natalia , Kulkova Marianna
Published: July 2019

Introduction. The article considers the features of cattle breeding and consumption of meat products in the Eneolithic cultures (the Samara culture) and the Early Bronze Age cultures (the Repin stage of the Pit Grave culture) on the territory of the Southern Urals (the Samara Trans-Volga region). The paper specifies the chronology of these cultures on the base of radiocarbon dating. The main site for the study was Turganik settlement located in the Southern Ural region (Orenburg region). Methods. More than 800 m2 of the settlement area was excavated. There were six paleosoil layers. Four upper layers were empty, without artifacts. The sixth layer contained Eneolithic finds. The fifth layer contained finds of the Early Bronze Age. The archaeozoological collection was analyzed in accordance with the methodological scheme developed by E.E. Antipina. For radiocarbon dating collagen was treated from bone samples on the base of the standard procedure and radiocarbon activity was measured by Quantulus 1220 low background scintillation counter. Analysis and Results. As a result 32 radiocarbon dates were obtained on animal bones and on organics from pottery of different types from different cultural layers of Turganik settlement. The Eneolithic complex includes ceramics, flint and bone tools. The paper specifies the finds of developed and later stages of the Samara culture. The artifacts of the second stage of the Samara culture were dated to 4900–4500 cal BC. The artifacts of the later stage belong to the period of 4300–3800 cal BC. We suggest that from the Early Eneolithic local people practiced cattle breeding without agriculture. Hunting played a secondary role and fishing was poorly developed. Beef was the main food in the people’s diet during the Eneolithic period. The Early Bronze Age assemblage includes ceramics of the Repin stage of the Pit Grave culture, stone macro-tools, flint arrowheads, items made of bones and copper, slags and scarps of copper ore. The technological analysis supported that ceramics belong to the Pit Grave culture. The layer age is from 3800 to 3300 cal BC. During the Repin stage the role of sheep breeding was increased and consumption of sheep meat prevailed in comparison with the Eneolithic period. This is an evidence of the transition to the nomadic form of stock breeding.
Forest Teams as an Alternative Service of the Mennonites in the Russian Empire Until 1914
Authors: Erokhina Ol’ga
Published: July 2019

Introduction. In the Russian Empire, the Mennonites, like German colonists, had numerous privileges, including they were not drafted for military service. This privilege was abolished after the Edict of 1874 was issued. However, they could not serve in the army due to their religious views.

Methods and materials. The source base of the topic under study includes mainly written materials. Therefore, to show how the “military service” of the Mennonites was organized in forest teams, we used materials from the archives of the Russian State Historical Archive (387, 1246, 1282, 1292). Based on the documentary material with the use of the historical systemic method, we restored the chronology of the negotiation process between the authorities and the Mennonites on the introduction of alternative service. The paper reveals the terms of the agreement between the Mennonites and the Russian authorities. The Mennonites were forced to agree with these conditions in order not to take up arms.

Analysis and Results. Based on the archival material, we found that the reaction from the Mennonites was immediate. On the one hand, they tried to establish a dialogue with the authorities on the resolution of an alternative civilian service, and on the other hand, many began to migrate to America. As a result, the Mennonites succeeded in obtaining the right to serve in forest teams and to submit to the Ministry of State Property. It was revealed that the subordination to the civil department instead of the military one changed their position from unranked soldiers to obligated workers. Therefore, they received monetary reward for their work. It was established that the Mennonite communities built and equipped barracks at their own expense; bought clothing and food; delivered the Mennonites to the place of service; paid rent for the ground areas allocated for agricultural needs to forest teams. A working day of obligated workers was strictly regulated and did not differ from the army one in fact. In the first half of the day, they always dealt with clearing and improvement of forests, and mainly with their protection. In their spare time the Mennonites played musical instruments and read books. In addition, they were necessarily taught reading and writing in Russian. Educational supplies were purchased at the expense of the team. Despite many difficulties in organizing and maintaining forest teams, many of the Mennonites performed their duties conscientiously and were encouraged by the ministry for good service more than once.
The Projects of Agricultural Diversity (The Lower Volga Region, the Kalmyk Region and the German Republic in the 20–30-s of the 20th c.)
Authors: Ivanova Tat’jana , Klejtman Aleksandr
Published: July 2019

Introduction. The analysis of agricultural diversity projects made on the materials of studies in the Lower Volga region, the Kalmyk Region and the German Republic allows to solve 2 problems. Firstly, it defines the possibilities of expanding the species of industrial crops, medicinal and aromatic herbs. Secondly, it suggests the idea to increase the distribution of certain farmlands (namely of the Volga-Akhtuba floodplain) by means of elaborating the directions of their development. The article contains the results of research works performed during the 20–30s of the 20th century on the territory of current Astrakhan, Volgograd, Saratov regions and the Republic of Kalmykia. The work evaluates the opportunities of using these territories for increasing gross regional product.

Methods and materials. The methods of the research: the principles of historicism and objectivity, analysis, synthesis, the historical and genetic method, the systematic approach. The works of N.I. Anisimov, V.P. Danilov, V.A. Ilinykh and others study collectivization, strengthening of agricultural material and technical resources. Since 90s of the 20th century the representatives of non-historical sciences have been studying the conditions of flora in different regions of Russia, the specifics of economic use of unique natural objects.

Analysis. The article gives the analysis of projects on cultivating new species of industrial, medicinal, aromatic crops, sericulture. The paper considers the plans of developing the Volga-Akhtuba flood plain as well. Using the previous experience improves modern developments.

Results. The authors came to the conclusion on the possibility of cultivating new industrial crops (sunflower, mustard, linen, tobacco, hemp, cotton, soy, castor bean, kenaf, peanut, poppy), medicinal and aromatic herbs and carried out zoning of planting, including with ensuring the complex use of the Volga-Akhtuba flood plain. An increased acreage for sericulture was planned. The population was distrustful to plans for cultivating new cultures. This was due to the lack of knowledge in agronomy and errors in the choice of planting material. The productivity became lower than at pilot farms. The reduction in research financing did not give the chance to overcome these negative factors. Besides, obtaining good results demanded irrigation, which passed in the Lower Volga region in the middle of the 20th century. Now using specified developments can become one of the directions of developing the agriculture of the Lower Volga region as the problems of conducting agriculturalproduction stated above become more surmountable on current material and technical resources. Earlier the crops under consideration were grown up in Ukraine, Uzbekistan, Kyrgyzstan. Now these states are independent, so it is reasonable to produce a larger range of agricultural products in Russian regions to improve food security.
Twelve tips for bringing competencies into continuing professional development: Curriculum mapping

Published: July 2019

This article was migrated. The article was marked as recommended. There is a growing worldwide awareness in the field of health professions education and research that a successful implementation of competency-based medical education (CBME) requires embracing all stages of professional development (from undergraduate, through residency to continuing education). However, despite increased levels of cognizance and even enthusiasm about the importance of the entire continuum for the ultimate goal of improved healthcare, much work still remains as CBME principles are not widely adopted in continuing professional development (CPD). Much has been written about the process of competency-based curriculum development (e.g., the formation and development of meaningful and measurable outcomes) in undergraduate studies and postgraduate training, but not in CPD. If we expect a CPD curriculum to integrate CBME, competencies must be developed and clearly specified how they will fit into a coherent and implementable curriculum structure. In this article, we describe existing practices some educational institutions have, including our experiences in the Office of CPD at the University of Ottawa, Canada, in designing a competency-based curriculum and provide 12 tips for those who begin their journey of organizing, developing, and implementing such curricula. We conclude that in order to translate a competency-based approach into CPD, educational programs will have to refine curricula across health professionals' education using curriculum mapping as an important tool of curriculum development and evaluation.
Experimental study on the seismic behaviour of reinforced concrete frames with different infill masonry
Authors: Wang Lei , Qian Kai , Fu Feng , Deng Xiao-Fang
Published: July 2019

Six half-scale, single-storey, one-bay frame specimens were tested to investigate the seismic behaviour of masonry-infilled reinforced concrete (RC) frames subjected to lateral loading. The variables investigated included the type of masonry infill and the types of openings. The crack patterns, failure modes, load–displacement hysteretic loops, stiffness degradation and energy dissipation capacity are presented and discussed. It was found that the infill wall (with or without openings) significantly improved the behaviour of the RC frame. Moreover, as expected, the frames infilled with higher strength masonry performed better than those infilled with relatively low-strength masonry. It was also found that openings may be a detriment to the stability of infill walls, with a concentric window opening found to have worse effects than an eccentric door opening. An analytical model is proposed to determine the load-resisting capacity of bare frames and infilled frames with reasonable accuracy.

Published: July 2019

En este trabajo se presenta la construcción de un prototipo de un sistema de monitorización de puertas y ventanas a través de una plataforma IoT. El objetivo fue diseñar un sistema que reporte a un servidor en la nube el cambio de estado, abierta o cerrada, de tres puertas y dos ventanas de la sala de equipos del centro de datos. Los cambios de estado son registrados por el servidor y por medio de una interfaz de usuario se muestran en línea los estados de las puertas y ventanas. La arquitectura del sistema se basa en una red inalámbrica de sensores integrada por un nodo central y cinco nodos de monitorización. Los nodos de monitorización están compuestos por una tarjeta PyBoard, dos sensores digitales de efecto Hall y una interfaz inalámbrica wifi. Al detectar un cambio de estado en puertas y ventanas, los nodos de monitorización lo notifican al nodo central, y este lo transmite al servidor por medio de un punto de acceso wifi. Cuando una puerta o ventana permanece abierta más de un período de tiempo configurable, se envía un mensaje SMS y de WhatsApp a un teléfono móvil. El alcance logrado en la transmisión wifi en la red fue 47 metros con línea de vista.

El calentamiento de agua en el sector residencial ecuatoriano se ha convertido en un espacio de investigación y desarrollo, debido al intento de mitigar el gasto corriente de las personas y a la vez contribuir de manera activa a los procesos de eficiencia energética que van tomando fuerza en el país. En el presente documento se muestra un análisis comparativo entre diferentes maneras de controlar la temperatura del agua para un sistema residencial utilizando un calentador eléctrico; se analizó la respuesta de un conversor AC/AC de control de fase directa que permite retrasar el ángulo de disparo de la onda de corriente alterna y la respuesta del control ON/OFF que activa o desactiva el calentador durante un número preestablecido de semiciclos de corriente alterna. Para las pruebas se instaló un prototipo de calentador eléctrico con un serpentín de 14 metros a base de resistencias eléctricas; con las respuestas de temperatura que se generan de cada conversor se procedió a identificar la función de transferencia de cada sistema ya que ambos difieren en su técnica de transmisión de calor y a la vez en su modelo matemático. Posteriormente se procedió a sintonizar un controlador PID para cada sistema, obteniendo buenos resultados de respuesta de temperatura en ambos casos, pero solo uno resultó eficiente en ahorro energético.

In this protocol we developed a method for the detection of the rearrangement of exons 9-12 of BRCA1 based on multiplex PCR. A multiplex PCR is performed for the detection of the normal and mutated alleles of exons 9-12 of BRCA1 gene, 500 and 900 base pairs respectively, and a second PCR for the detection of the mutated allele. Both PCRs are observed by means of electrophoresis in 1.5% agarose gel.

Industrial activities have a detrimental impact on the environment and health when high concentrations of pollutants are released. Phytoremediation is a natural method of utilizing plants to remove contaminants from the soil. The goal of this study was to investigate the ability ofCannabis sativaL. to sustainably grow and remediate abandoned coal mine land soils in Pennsylvania. In this study, six different varieties of industrial hemp (Fedora 17, Felina 32, Ferimon, Futura 75, Santhica 27, and USO 31) were grown on two different contaminated soil types and two commercial soils (Miracle-Gro Potting Mix and PRO-MIX HP Mycorrhizae High Porosity Grower Mix). Plants growing in all soil types were exposed to two environmental conditions (outside and in the greenhouse). Seed germination response and plant height indicated no significant differences among all hemp varieties grown in different soils, however on an average, the height of the plants grown in the greenhouse exceeded that of the plants grown outdoors. In addition, heavy metal analysis of Arsenic, Lead, Nickel, Mercury, and Cadmium was performed. The concentration of Nickel was 2.54 times greaterin the leaves of hemp grown in mine land soil outdoors when compared to greenhouse conditions. No differences were found between expression of heavy metal transporter genes. Secondary metabolite analysis of floral buds from hemp grown in mine land soil displayed a significant increase in the total Cannabidiol content (2.16%, 2.58%) when compared to Miracle-Gro control soil (1.08%, 1.6%) for outdoors and in the greenhouse, respectively. Molecular analysis using qRT-PCR indicated an 18-fold increase in the expression of the cannabidiolic acid synthasegene in plants grown on mine land soil.Thedata indicates a high tolerance to heavy metals as indicated from the physiological and metabolites analysis.

Buku teks Sejarah untuk SMA merupakan salah satu bentuk material yang digunakan untuk kepentingan pembelajaran di sekolah. Pembeljaran sejarah berfungsi untuk melestarikan memori kolektif dan nilai-nilai yang dianggap penting, salah satunya peduli lingkungan yang merupakan nilai penting dalam cara pandang ecocentris bagian dari green history. Penelitian ini bertujuan untuk mengungkap penggambaran dan representasi nilai green history dalam buku teks sejarah. Metode yang digunakan yaitu content analysis. Sumber data pada penelitian ini adalah buku teks Sejarah SMA kelas X berdasarkan kurikulum 2006 karya I Wayan Badrika yang diterbitkan oleh Erlangga. Hasil penelitian menunjukkan bahwa green history direpresentasikan dalam berbagai tema seperti kehidupan awal masyarakat Indonesia (masa berburu dan mengumpulkan makanan serta masa beternak dan bercocok tanam), dan peradaban kuno Asia-Afrika (Peradaban Sungai Shindu dan Gangga, Sungai Kuning, dan Sungai Eufrat dan Tigris). Green History perlu dipahami sebagai cara untuk mengembangkan pikiran peserta didik tentang pentingnya menjaga kelestarian lingkungan (understanding how nature sustains life) seperti pengambilan keputusan (decision making skills) di dalam melakukan berbagai tindakan di dalam kehidupan sehari-hari
KEMBALI KEPADA UNDANG-UNDANG DASAR 1945: DISKURSUS PEMBUKAAN UUD 1945 DALAM PERSPEKTIF SEJARAH
Authors: Pardi I Wayan
Published: July 2019

Tujuan penulisan artikel ini adalah 1) untuk mendeskripsikan dinamika perumusan Pembukaan Undang-Undang Dasar alenia ketiga pada tanggal 18 Agustus 1945, dan 2) untuk mendeskripsikan dinamika rumusan Pembukaan Undang-Undang Dasar alenia ketiga dari Republik Indonesia Serikat sampai Dekrit Presiden 5 Juli 1959. Metode yang digunakan dalam penulisan artikel ini adalah metode penulisan sejarah. Hasil temuan menunjukkan bahwa pada tanggal 18 Agustus 1945, atas usulan Mr. I Gusti Ketut Pudja Pembukaan Undang-Undang Dasar 1945 alenia ketiga yang berbunyi “Atas berkat Rahmat Allah…” telah diganti dengan “Atas berkat Rahmat Tuhan…”. Usulan tersebut juga tidak mendapatkan penolakan dari peserta sidang PPKI lainnya, sehingga Sukarno akhirnya mengesahkan Pembukaan tersebut di atas dengan persetujuan seluruh anggota sidang PPKI. Akan tetapi justru dalam Berita Republik Indonesia Tahun II No. 7 tanggal 15 Februari 1946 perubahan itu belum dilakukan. Oleh sebab itu, agar generasi selanjutnya tidak terkontaminasi oleh penyakit amnesia yang diderita pendahulunya, maka sudah seyogyanya Pembukaan Undang-Undang Dasar alenia ketiga harus segara dirubah menjadi “Atas berkat Rahmat Tuhan Yang Maha Esa”.

Gaza strip suffers from a serious shortage in water resources due to the continuous increase in population, life changes, political conditions and drought caused by climate change. Due to increased demand for water for domestic use, resulting accumulation of large quantities of wastewater in the treatment plant in Rafah. Therefore, reuse of treated wastewater is one of the most recently accepted approaches to save groundwater or domestic use. The aim of this research is to study the treated effluent quality from Rafah Treatment Plant, in addition to the effect of education level of the farmers on reusing treated wastewater for irrigation. A questionnaire was distributed to farmers to investigate the acceptance of using treated effluent for irrigation, meanwhile the effluent parameters tested were BOD, COD, TKN, NH4, NO3, P, Cd, Pb, and Cu accounted for 110, 250, 108, 127, 0.23, 17.9 mg/l, < 0.003, <0.001, and 19.9 µg/l. Most of reuse parameters were higher than the recommended levels for the effluent reuse based on the recommended Palestinian Standards for irrigation. About 80.7% of farmers accept using treated wastewater in irrigation and the Chi-square test analysis showed that, at P-value =0.00095 < α= 0.05, there is a close relationship between the educational level of farmers and the acceptance of using of treated wastewater in irrigation, as long as it is safe and healthy.

Petroleum is a mixture of hydrocarbon complexes with organic compounds from sulfur, oxygen, nitrogen and metal-containing compounds. These organic compounds can be used as substrate for bacterial growth. This study aimed to isolate and identify hydrocarbon degrading bacteria and phosphate solubilizing bacteria in oil-contaminated soil in Bojonegoro. This study used an exploration method to find each of the two types of hydrocarbon degrading bacteria and phosphate solubilizing bacteria from soil samples in Bojonegoro that contaminated by oil. Identification of isolates bacterial included macroscopic observations of bacteria, gram staining on bacterial cells and physiological tests. Macroscopic observations include the form of colonies, colony diameter, colony color, colony edge, and elevation. The physiological test using Microbact Identification System to determine the physiological characteristics of bacteria so that genera and types of bacteria can be known. The identification of organisms was based on changes in pH and use of the substrate. The results of data analysis were obtained from five types of bacteria from soil samples that contaminated by oil which were successfully isolated. After identification of species was done, four species of bacteria were obtained, namely Pseudomonas pseudomallei, Pseudomonas fluorescens-25, Flavobacterium odoratum, and Enterococcus sp.

This study has been conducted to investigate the flexural strength of Borassus Flabellifer Fiber/BFF reinforced polyester composite joint under static condition. Tests were carried out to study the flexural strength of double strap butt joint and single lap joint of BFF polyester composite. In addition, post observation of macroscope was used to map failure behavior. The results shown that the flexural strength of single lap joint is higher compared to double strap butt joint of  BFF polyester composite. The larger cross-sectional area and the existence of gap area could be the main reason for lower flexural strength generated by double strap butt joint of  BFF polyester composite. The failure of BFF polyester composite joints under flexural test indicated the brittle failure behaviour that fiber breakage was found to be the final failure mechanism which start with matrix cracking and fiber-matrix debonding failure mechanisms.

Trending topics in Twitter is a collection of certain topics that are widely discussed by users. This study aims to design a model and strategy for finding trending topics from data streams on Twitter. The research approach was carried out in four stages, namely twitter data collection, preprocessing data, data analysis with sequential K-Means clustering and information processing. Sequential K-Means is used because it can receive input data sequentially and the cluster center can be updated. Testing of the model is carried out in three scenarios where each scenario is distinguished between the amount of data, time and parameter values. After that, evaluation of the results of clustering will be done using the Dunn Index method. Trending topics twitter application were created using the R language and produce output in the form of histograms. There are five topics being the trending topics in New York before the new year. The topic of "Times" relates to the presence of a new year's celebration night concert in Times Square. The "Hours" topic deals with the calculation of time and seconds towards 2017. "Eve" and "Party" topics relate to celebrations and the topic "Resolution" relating to hope and change for New Yorkers in in 2017.

The article proposes to know how the formation of the national identity took place in the tutelary institutions of the first Francoism, during the stage of primary schooling, in the city of Madrid. To do this, a documentary collection of reports on practices and the statistics of the yearbooks of the National Institute of Statistics are used. Applying a historical-educational methodology, the texts and photographs of the archive are analyzed around three categories: national identity, educational practices, and the gender perspective. The results show the politicization and indoctrination to which the students were subjected in these centers, in which the symbology, the school subjects and the daily practices became tools to train in their own education of each sex and social class. The study advances the need to carry out new research with alternative sources and in other contexts in order to know how this education was lived by those who suffered the "protection" of National-Catholicism in the post-war tutelary institutions.
