Abstract: This research aimed to examine the progressive collapse of dual system building structures due to the loss of one or more structural elements that lead to successive collapse of other elements. Three cases of building structures were analyzed in this study using finite element software. Several columns on the first floor of the structure was removed and then the analysis was conducted to each structure until the progressive collapse existed. The nonlinear statics analysis was used to examine the location of the critical column while the linear statics analysis was carried out to find the demand capacity ratio, the bending moment ratio and robustness indicator as suggested by GSA 2003 and SNI 2847-2013. The results showed that the structure denoted in case 1 and case 2 that was loaded comply with GSA 2003 experienced the progressive collapse. On the other hand this phenomenon did not appear on the structure that was loaded in accordance with SNI 2847-2013. Furthermore, there was an increase in the bending moment capacity of the column/beam on all cases that were loaded comply with SNI 2847-2013 and GSA 2003.

The most frequent problem that occurred in a box culvert is sedimentation. Sediments can be transported by changes in the water flow velocity, which can be influenced by changes of depth, h, of the channel bed. This research studies the change in h1 to h2 = 1,1 h1, 1,3 h1, 1,5 h1, 1,8 h1, and 2 h1, by simulation using SSIIM 1 program. The graph of the grain size distribution shows that the sediment consists of 99% of sands and 1% of silt, which its diameter of d50 = 0.8 mm and d90 = 4 mm. The discharge is 0.328 m3/s. The results, the deeper of the bed channel changes, the slower the flow velocity. The bed shear stress in changing the bed channel is smaller than the critical bed shear stress, and it makes the sediment stays. Based on the results, the variation of h2 = 1,1 h1, is preferred in sediment management.

Keruntuhan geser pada balok beton bertulang tanpa tulangan geser merupakan keruntuhan yang sangat getas. Sejumlah besar penelitian eksperimental mengenai keruntuhan geser balok beton bertulang menunjukkan fakta bahwa kegagalan geser balok merupakan proses yang kompleks dan adalah efek dari berbagai parameter yang memberikan pengaruh signifikan, diantaranya kuat tekan beton (f′c), rasio bentang geser-tinggi efektif (a/d), rasio tulangan longitudinal (), dan tinggi efektif penampang (d). Oleh karena itu, upaya untuk memperoleh model prediksi yang mampu memberikan hasil yang paling mendekati mekanisme geser menjadi daya tarik kuat bagi para peneliti. Penelitian ini bertujuan untuk mengevaluasi dan membandingkan enam perumusan geser berdasarkan ACI 318, EC2, CSA A23.3, BS 8110, NZS 3101, dan CEB-FIP dengan data eksperimen kuat geser beton yang diperoleh dari literatur; mengusulkan suatu persamaan desain untuk memprediksi kekuatan geser beton (Vc) balok beton bertulang tanpa tulangan geser; serta merekomendasikan model usulan sebagai salah satu alternatif perhitungan geser bagi praktisi desain selain perumusan geser berdasarkan standar. Persamaan yang diusulkan berasal dari hasil analisis regresi dengan menggunakan 276 data hasil uji geser balok yang dikumpulkan dari 20 sumber dengan berbagai variabel yang mempengaruhi kekuatan geser. Kekuatan geser beton hasil eksperimen sebelumnya dibandingkan dengan model usulan dan ke-enam perumusan geser beton tersebut diatas. Hasil evaluasi ke-enam standar menunjukkan bahwa standar beton menurut CEB-FIP dan BS 8110 menunjukkan hasil prediksi yang lebih baik dan konservatif terhadap hasil tes daripada standar ACI 318-14, NZS 3101, CSA A23.3, dan EC2. Perumusan geser berdasarkan ACI 318-14, CEB-FIP dan BS 8110 menghasilkan prediksi kekuatan geser beton cenderung aman dibandingkan ke-tiga standar beton lainnya (NZS 3101, CSA A23.3, dan EC2). Dari hasil analisis, diusulkan dua persamaan kekuatan geser beton balok bentang pendek dan panjang tanpa tulangan geser yang dibatasi dengan rasio kelangsingan balok, a/d ≥ 2,5 dan 1,5 ≤ a/d < 2,5. Model usulan cukup akurat (applicable) memprediksi gaya geser beton Vc balok beton bertulang bentang pendek maupun panjang tanpa tulangan geser pada rentang variabel yang dipertimbangkan dalam penelitian ini.

Movilidad residencial y anclajes en la Zona Metropolitana del Valle de México: división socioespacial en las colonias populares periféricas
Authors: Valette Jean-François
Published: May 2022

En la metrópoli de México, como en otras partes, la movilidad residencial intraurbana es un motor importante de la reconfiguración de la división socioespacial. En las colonias populares la pobreza es predominante; sin embargo, esta característica resulta insuficiente para explicar dichos espacios. El objetivo del artículo es comprender los mecanismos de los anclajes residenciales, así como las recomposiciones socioespaciales que éstos implican. A través del análisis de datos censales y encuestas exploratorias, se pone énfasis en la articulación de los lugares y la variedad de las experiencias de sus habitantes, volviendo obsoletos los enfoques únicos en términos de relegación-consolidación sistemática, o fragmentación.
Philosophical Category of Integration as a Condition of Economic Systems Development
Authors: PUZANOVA Irina
Published: May 2022

The article analyzes the concept of integration in dialectic unity with differentiation by its application during the study of economic systems development, including supply chains. The differentiation is a problem, i.e. the nature of occurrence of a critical situation in the system stipulating the need to generate new goals for the interaction of its components; integration is a solution to a problem, the basis for the transition to a new stage of system development. The study results reveal that the main integration drivers are factors that ensure the complementarity and compatibility of system components. It is stated that the functionality is the first condition for integration, that is, the potential for the unhindered implementation of individual goals and objectives which are not destructive to the system. The homology is the second condition, which ensures the compatibility of system components. The integratedness is the third condition that can be defined as the degree of firmness of links between system parts on which the system stability and viability depend. The author notes the importance of permanent diagnostics of connections within and between the economic system and environment since inter-organizational links constitute a differentiation factor.

The study aims to determine the philosophical and methodological aspects of advanced vocational training for students at school. The article uses philosophical methods to identify the main approaches of modern philosophy to the problem of advanced vocational training. A set of empirical methods was applied: literature study, survey (oral and written). To achieve the goal, the following tasks were solved: considering approaches to the concept of advanced vocational training of schoolchildren; highlighting the main aspects of advanced vocational training of schoolchildren; studying the current condition of the arrangement of advanced vocational training of schoolchildren. The problem of this research lies in the issue of disclosing the structure of advanced vocational training. Four units were identified, by the development of which one can judge on the degree of orientation of the educational process in a school towards the vocational training of students. The results of a survey of schoolchildren revealed that the most developed unit of advanced vocational training is the formation of meta-subject competencies, taking into account the professional orientation of the student. Similarly, with meta-subject competencies, average indicators are observed in the assimilation of labour skills.

To maintain their competitive state, business entities need to transform the existing business model by integrating smart technologies, the Internet of Things and artificial intelligence into its basis. The emergence of new formal and informal institutions should regulate the rules of behaviour of economic agents in the digital economy. To this end, it is necessary to form and develop a legal framework that regulates the relationship between customers and owners of digital platforms. We believe that digital ecosystems will have a certain interest in the new society. Unlike traditional models of interaction between actors, digital ecosystems will create a single information field and a new form of constructive cooperation and coordination between participants in the virtual space. The state should become the initiator of creating this kind of digital ecosystem, which will make it possible to implement the mechanism of reasonable digital protectionism, the purpose of which will be to protect the interests of users and owners of digital platforms in cyberspace.

: Bu çalışmada ilkokul 3. ve 4. sınıf ders kitapları etkinliklerinin bilimsel süreç, yaşam ve mühendislik becerilerini kazandırması açısından incelenmesi amaçlanmıştır. Fen bilimleri ders kitabı etkinliklerinde bilimsel süreç, yaşam ve mühendislik becerilerine ne derece yer verildiğinin belirlenmesi amacıyla doküman incelemesi yöntemi kullanılmıştır. Çalışmanın örneklemini Millî Eğitim Bakanlığı Talim ve Terbiye Kurulu Başkanlığının kararıyla 2019-2020 öğretim yılından itibaren beş yıl süreyle kabul edilmiş 3. sınıflar için TUNA ve MEB yayıncılık, 4. sınıflar için MEB ve İPEKYOLU yayıncılık ders kitapları oluşturmaktadır. Çalışmada toplam 141 etkinlik incelenmiş olup veriler betimsel içerik analizi tekniği kullanılarak analiz edilmiştir. Çalışmadan elde edilen bulgular doğrultusunda 3 ve 4. sınıf için hazırlanan ders kitaplarının tüm yayınlar incelendiğinde becerileri kazandırma açısından yetersiz olduğu, yayınevleri arasında öğretim programında hedeflenen beceriler göz önüne alındığında etkinliklerin oranında anlamlı bir fark olmadığı görülmektedir. Fen bilimleri öğretim programının hedeflediği amacına ulaşabilmesi için ders kitaplarında yer verilen etkinliklerin bilgi düzeyinden sentez düzeyine çıkarılmasının etkinliklerin becerileri daha fazla kapsar hale gelmesine temel olacağı düşünülmektedir. Bu nedenle ders kitabındaki etkinliklerin oluşturulma sürecinde, bilimsel süreç, yaşam ve mühendislik tasarım becerilerinin kullanımını ve gelişimini odaklayan etkinlikler sahadaki öğretmen ve araştırmacılardan geri dönütler alınarak geliştirilmesi önerilerine yer verilmiştir.
Effect of Dune Sand as Sand Replacement on the Mechanical Properties of the Hybrid Fiber Reinforced Concrete
Authors: Dawood Abbas Oda , Jaber Ahmed Mjbel
Published: May 2022

This paper presents an experimental work to study the effect of dune sand as an alternative to sand on the mechanical properties of hybrid fiber reinforced concrete. 24 concrete mixes were prepared, 6 of them without fibers and containing different proportions of dune sand, and 18 concrete mixes with the same proportions of dune sand but containing long and short single and hybrid steel fibers. For the purpose of studying the properties of hybrid concrete, including measuring the workability of fresh concrete, examining the compressive strength, dry density, split tensile strength, Flexural strength, ultrasonic pulse velocity testing, water absorption of hardened concrete. The main parameters were the proportions of dune sand (20 %, 40 %, 60 %, 80 %, and 100 %) in addition to the ratio 0 % without dune sand. Two types of steel fibers were used: straight steel fibers (short) with a length of 13 mm and hook end steel fibers (long) with a length of 50 mm, It is added to concrete (single or hybrid) with a total volume ratio of 1 % of the concrete volume. The tests that were conducted showed that sand dunes affect the compressive strength, especially when the percentage increased by more than 40 %, where the compressive strength of concrete decreases by 39 % when the replacement ratio reaches 100 %, but it improves with the addition of single or hybrid fibers. Also, the workability from high to medium level decreases by 30 % with increasing dune sand content, the addition of steel fibers along with dune sand significantly reduced the workability. The tensile and flexural strength decreases with the increase in the sand dune rate, but at a lower rate than the compressive strength, which was 29.3 %, 21.1 % for splitting and flexural tensile strength, respectively. The addition of steel fibers improved the mechanical properties of the hybrid concrete, which can compensate for most of the lost strength due to the increase in sand dunes ratios. The study also showed that the use of long fibers (hook end) gives better results than straight fibers. But in the case of using hybrid fibers, we can get an improvement in the mechanical properties more than using one type of fiber.
The Struggle for Influence on the Roof of the World

The key research task addressed in this article is to identify, using the example of Tajikistan, the main methods of struggle for influence currently used by leading international actors. Tajikistan is considered both as an autonomous actor with significant internal sources of development, and as an object of influence from more powerful states. The article analyses the nature of the actions taken by the United States, China, and Russia to gain political, economic, and cultural influence in this Central Asian republic. These states act as investors and trade partners in Tajikistan, they gain influence in education by promoting the study of English, Chinese and Russian languages. While the Western investments tend to decrease, the United States retains its influence, primarily in the financial sector. It also attracts the most active, young, educated citizens of Tajikistan to US for permanent residence. Of all countries, China has the most consistent and effective investment strategy, which includes the allocation of investment loans to Tajikistan, the creation of infrastructure facilities through these loans by Chinese companies and labor. The gradual establishment of China's dominance in the economic sphere is accompanied by an increase in China's presence in education and culture. Russia is Tajikistan’s main trading partner, the most important security provider, and destination for a critical number of labor migrants. There is a fundamental difference in the approaches of Russia, China, and the United States to Tajikistan: the activities of Russia and China are focused on maintaining and strengthening stability in Tajikistan, the United States, in the context of their campaign of tough confrontation with Russia, is ready to assist in destabilizing the situation in Tajikistan, using Islamists for this purpose.
Peter The Great's Foreign Policy in the Assessments of Russian Conservatives of the 19th Century
Authors: Linkova E. V.
Published: May 2022

The article reconstructs the views of Russian conservatives on the Russia’s international position and foreign policy under Peter I. His military victories, and successes in diplomatic field made him popular among conservatives of the 19th century: N. Karamzin, F. Tutchev, M. Pogodin, S. Tatishchev, V. Lamansky, etc. In their studies they focused on Russia’s international posture in the late 17th– early 18th century, comparing the main features of Peter's diplomacy with his those of his descendants. The conservatives, while criticizing the emperor for undermining the tradition, imitating the West, and widening the socio-cultural rift in the society, highly appraised Peter’s foreign policy. They attributed the success to the foreign policy strategy based on national interests. This strategy and Peter’s personality fared better compared to the times of «palace coups», and personalities of Catherine II, Alexander I, and Nicholas I. Peter I «in his relations with foreign powers...was guided solely by the consciousness of our national benefits and needs, while strictly protecting the honor and dignity of the sovereign and the state». The conservatives criticized the emperor's 19th century heirs for what they saw as abandonment of national interests in favor of pan-European ones.
Proclamation of the All-Russian Empire – the Beginning of the Way to the Great Power Status
Authors: Artamonov V. A.
Published: May 2022

Many historians believe that Russia became a great power either as a result of the Poltava victory in 1709, or after the Nystadt Peace of 1721. It is difficult to agree with this. Peter the Great’s rule indeed produced a combat-ready regular army, a guard, an officer corps, a navy with shipyards, military bases, and coastal artillery. There was an upsurge in the metallurgical industry and mining. Schools with high-quality military and secular education, the Academy of Sciences, the Senate, and the Synod were established. St. Petersburg was founded. Talented and enterprising individuals were promoted to military, diplomatic and administrative posts. The main factor in the rise of the state was military modernization. The main geopolitical achievement of Peter I was the conquest of full access to the Baltic Sea. However, a limited resource base, military and diplomatic defeats and setbacks did not allow Russia to rise to the rank of a great power. The disasters of Narva in 1700 and on the Prut River in 1711 were painful. Russia lost access to the Sea of Azov, the city of Azov, city of Taganrog, the Azov squadron, shipyards and shipbuilding in the Voronezh Territory were lost. The damage from three treatises with the Ottomans in 1711-1713 was great. Russia has lost all of Zaporozhye. The demarcation of the borders of 1714 threw Russia back several hundred kilometers from the Black Sea region. In 1719, the Russian military force was squeezed out of Central Europe – from Mecklenburg. The sphere of influence of Russia after the victorious Peace of Nystad in 1721 was established only in Northern and Eastern Europe – in the Polish-Lithuanian Commonwealth, the Swedish and Danish-Norwegian kingdom, partly in Prussia. The tsar had no claims to hegemony in Europe and no claims to join the circle of the then great powers. Russia was not a great power like the Habsburg monarchy, France, Great Britain, and the Eurasian-African Ottoman Empire. Russia could not compare with the great powers of that time neither in terms of economic (industrial, financial) power, nor in terms of the intensity of expansionism. The entry of the Russian Empire into the system of international relations as one of the five great powers – France, Great Britain, Austria, Prussia, and Russia – occurred during the Seven Years War of 1756-1763. Another rise to great power took place during the reign of Catherine II. The apogee of greatness and the culmination of Russia's influence on European affairs was the Congress of Vienna in 1814-1815.

Aim. To synthesize hexahydrospiro[cyclopropane-1,10’-pyrido[1,2-c]quinazoline] and 2-λ5-benzo[f][1,4,2]diazaphosphepine derivatives – new N-P containing heterocyclic compounds with the 6-azaspiro[2.5]octane fragment.Results and discussion. A new analog of the powerful electrophilic reagent – “Alder dimer” ‒ was obtained from the interaction of triflic anhydride and spiro(4-cyclopropane) piperidinyl formamide, and further used to synthesize new Nʹ-PV- and PIII-substituted Νʹ-phenyl, Νʹʹ-hexahydro(azaspiro)octylformamidinium salts – precursors of acyclic N-phosphorylated diamino carbenes with a spiroamine group. It has been shown that acyclic N-phosphorylated diaminocarbenes are transient species affording various products. The structure of the final product is primarily determined by nature of the phosphorus-bearing substituent, namely a phosphoryl or phosphino-group. N-PV-substituted carbene undergoes a 1,2-phosphorus shift with the formation of (selenophosphoryl)formamidine in a high yield. For N-PIII-substituted carbene a compatible 1,3-H shift also occurs with the formation of an intermediate azomethine ylide converted into a new heterocyclic system – hexahydrospirocyclopropane -1,10’-pyrido[1,2-c]quinazoline. Under the action of acid an unexpected further expansion of the 6-member ring occurs with the formation of a diazepine derivative.Experimental part. The reaction of Alder reagent with N-PV-seleno phosphoryl arylamides afforded N-phosphorus substituted formamidinium salts, which are easily reduced to PIII analogues. In addition to the corresponding formamidines, the new N-phosphorylated spiroamine-containing polycyclic system was isolated from the reaction mixture formed by the deprotonation of such salts with a strong non-nucleophilic base.Conclusions. The Alder reagent approach allows synthesizing precursors of acyclic formamidine carbenes with the spiroamine group. Such carbenes are unstable. By converting these compounds N-PIII-substituted tetrahydropyrimidine and diazaphosphepine derivatives with the 6-azaspiro[2.5]octane fragment have been obtained for the first time.
Analisis Kehilangan Air Irigasi Saluran Sekunder pada Daerah Irigasi Dakaino

Published: May 2022

Abstrak

Irigasi merupakan bentuk kegiatan penyediaan pengambilan, pembagian, pemberian, dan penggunaan air untuk pertanian dengan menggunakan satu kesatuan saluran dan pembangunan berupa jaringan irigasi. Air yang mengalir dari saluran primer menuju ke sawah sering terjadi kehilangan air sehingga dalam perencanaan selalu dianggap bahwa seperempat sampai sepertiga dari jumlah air yang diambil akan hilang sebelum air itu sampai di sawah. Kehilangan air yang terjadi erat hubungannya dengan efisiensi. Besaran efisiensi dan kehilangan air berbanding terbalik. Bila angka kehilangan air naik maka efisiensi akan turun dan begitu pula sebaliknya. Sedangkan kehilangan air adalah selisih antara jumlah air yang diberikan dengan jumlah air yang digunakan.  Tujuan penelitian ini untuk menganalisis besarnya kehilangan debit air, nilai kekasaran, dan efesiensi saluran pada saluran D.I.  Dakaino. Daerah Irigasi (D.I) Dakaino yang merupakan salah satu Daerah Irigasi yang masuk dalam Wilayah Sungai Halmahera Timur. Terletak di Kecamatan Wasile Timur Kabupaten Halmahera Timur Provinsi Maluku Utara dengan luas areal layanan ± 7.547 Hektar. Penelitian ini dilakukan pada Saluran beton pracetak.

 

Abstract

Water Loss Due to Changes in Channel Roughness in the Dakaino Irrigation Area. Irrigation is a form of providing activities for taking, sharing, giving, and using water for agriculture by using a single channel and developing an irrigation network. Water that flows from the primary channel to the rice fields often loses water so that in the planning it is always assumed that a quarter to a third of the total water taken will be lost before the water reaches the fields. The water loss that occurs is closely related to efficiency. The amount of efficiency and water loss are inversely proportional. If the water loss rate increases, the efficiency will decrease and vice versa. Meanwhile, water loss is the difference between the amount of water supplied and the amount of water used. The purpose of this study was to analyze the amount of water discharge loss, roughness value, and channel efficiency in the D.I channel. Dakaino. Dakaino Irrigation Area (D.I) which is one of the irrigation areas included in the East Halmahera River Region. Located in East Wasile District, East Halmahera Regency, North Maluku Province with a service area of ± 7,547 hectares. This research was conducted on precast concrete channels.
